ITEM 9.   SALES OF EQUITY SECURITIES PURSUANT TO REGULATION S.

    Pursuant to a purchase agreement (the "Purchase Agreement") dated October
7, 1997, among the Company and Bear, Stearns & Co. Inc. ("Bear, Stearns") and
Chase Securities Inc. ("Chase" and together with Bear, Stearns, the "Initial
Purchasers"), on October 14, 1997, the Company sold $150,000,000 ($130,000,000
plus $20,000,000 pursuant to the exercise of the over-allotment option granted
to the Initial Purchasers) aggregate principal amount of  Notes to the Initial
Purchasers at an initial offering price of 100% of the principal amount thereof,
less 2.825% gross commission.

    The Initial Purchasers advised the Company that the Notes were to be resold
at 100% of the principal amount thereof (i) to qualified institutional buyers in
reliance on Rule 144A under the Securities Act of 1933, as amended (the "Act"),
and to institutional "accredited investors" within the meaning of Rule
501(a)(1), (2), (3) or (7) under the Act, that agreed in writing to comply with
the transfer restrictions and other conditions set forth in the Purchase
Agreement and (ii) outside the United States to certain persons in reliance on
Regulation S under the Act.  The Initial Purchasers advised the Company that
$3,000,000 aggregate principal amount of Notes were sold outside the United
States to certain persons in reliance on Regulations S under the Act.

    In connection with sales of the Notes outside the United States, each
Initial Purchaser agreed that, except for sales described above, it would not
offer, sell or deliver the Notes to, or for the account or benefit of, U.S.
persons (as defined in Regulation S under the Act) (i) as part of such Initial
Purchaser's distribution at any time or (ii) otherwise until 40 days after the
later of the commencement of the offering of the Notes and the last closing date
with respect to the Notes, and that it would send to each dealer or distributor
to whom it sold such Notes during such period a confirmation or other notice
setting forth the restrictions on offers and sales of the Notes within the
United States or to, or for the account or benefit of, U.S. persons.

    The Notes were issued under an indenture, dated as of October 14, 1997 (the
"Indenture"), between the Company and The Bank of New York, as trustee.  The
Notes represent general unsecured subordinated obligations of the Company.  The
Notes are convertible into shares of the Company's Common Stock, par value $.01
per share (the "Common Stock"), at the option of the holder thereof, at any time
after 60 days following the latest date of original issuance thereof through
October 11, 2002, subject to prior redemption or repurchase, at an initial
conversion price of $55.335 per share.  The conversion price is subject to
adjustment (under formulae set forth in the Indenture) upon the occurrence of
certain events, including, but not limited to: (i) the issuance of Common Stock
as a dividend or distribution on the outstanding Common Stock; (ii) the issuance
to all holders of Common Stock of certain rights, options or warrants entitling
them (for a period expiring within 45 days after the date fixed for
determination of stockholders entitled to receive such rights, options or
warrants) to purchase Common Stock at less than the current market price; (iii)
certain 


                                       3

<PAGE>

subdivisions, combinations and reclassifications of Common Stock; (iv) 
certain defined distributions to all holders of Common Stock of capital stock 
of the Company (other than Common Stock) or evidences of indebtedness of the 
Company or assets; (v) certain cash distributions to all holders of Common 
Stock; and (vi) the purchase of Common Stock pursuant to a tender offer made 
by the Company or any of its subsidiaries in certain defined circumstances.

    Pursuant to a registration rights agreement (the "Registration Rights
Agreement") dated October 14, 1997, among the Company and the Initial
Purchasers, the Company has agreed to file with the Securities and Exchange
Commission a registration statement for an offering to be made on a continuous
basis pursuant to Rule 415 under the Act with respect to resales of the Notes
and the Common Stock issuable upon conversion of the Notes.  Upon the failure by
the Company to comply with certain of its obligations under the Registration
Rights Agreement, liquidated damages will be payable on certain of the Notes.

Dear Sirs:

         CellStar Corporation, a Delaware corporation (the "COMPANY"),
proposes, subject to the terms and conditions stated in this Purchase Agreement
(this "AGREEMENT"), to issue and sell to the several Initial Purchasers named in
Schedule I hereto (the "INITIAL PURCHASERS") an aggregate of $130,000,000
principal amount of its 5% Convertible Subordinated Notes due 2002 (the "FIRM
NOTES").  In addition, the Company proposes to grant to the Initial Purchasers
an option, for the sole purpose of covering over-allotments in connection with
the sale of the Firm Notes, to purchase up to an additional $20,000,000
principal amount of its 5% Convertible Subordinated Notes due 2002 (the
"OPTIONAL NOTES") as provided in Section 2 below.  The Firm Notes and any
Optional Notes purchased by the Initial Purchasers are referred to herein as the
"NOTES".

         The Notes are to be issued pursuant to an indenture to be dated as of
October 14, 1997 (the "INDENTURE") between the Company and The Bank of New York,
as trustee (the "TRUSTEE"), and, except as otherwise provided in the Indenture,
will be convertible into shares of the Company's common stock, par value $.01
per share (the "COMMON STOCK"), on the terms set forth therein. The holders of
the Notes will be entitled to certain registration rights provided under a
Registration Rights Agreement to be dated October 14, 1997 (the "REGISTRATION
RIGHTS AGREEMENT") between the Company and the Initial Purchasers.

circular dated October 7, 1997 (as supplemented or amended from time to time
with the written consent of the Company and Bear, Stearns & Co. Inc., as the

court decree, statutes, ordinances, rules, regulations, judgments or court
decrees) applicable to it or any of its assets or properties (whether owned or

environment of any Hazardous Material (as defined below) at any location,

or procedures), trademarks, service marks and trade names, computer programs,
technical data and information (collectively, the "INTELLECTUAL PROPERTY")
presently employed by them in connection with the businesses now operated by
them and, except as disclosed in the Offering Circular, the Company and its
subsidiaries have not received any notice of infringement of or conflict with
asserted rights of others with respect to any of the foregoing.  The use of the
Intellectual Property in connection with the business and operations of the

Subsidiaries or that are due and payable have been paid, other than those being
contested in good faith and for which adequate reserves have been provided or

to so pay would not have a Material Adverse Effect.  To the knowledge of the
Company, there are no material proposed additional tax assessments against the
Company or its Significant Subsidiaries or the assets or property of the Company
or its Significant Subsidiaries.

         (z)  As of the date hereof, no event has occurred nor has any
circumstance arisen which, had the Notes been issued on the date hereof, would
constitute a default or Event of Default (as defined in the Indenture).

         (aa) Neither the Company nor any of its affiliates has not taken and
will not take, directly or indirectly, any action designed to cause or result
in, or which constitutes or that might reasonably be expected to constitute, the
stabilization or manipulation of the price of the Notes to facilitate the sale
or resale of the Notes in contravention of Regulation M under the Securities Act
and the Exchange Act.

         (bb) Other than as disclosed in the Offering Circular, there are no
holders of securities of the Company who, by reason of the execution by the
Company of this Agreement or any other Transaction Agreement or the consummation
by the Company of the transactions contemplated hereby and thereby, have the
right to request or demand that the Company register under the Act or analogous
foreign laws and regulations securities held by them that have not been waived.

         (cc) When the Notes are issued and delivered pursuant to this
Agreement, the Notes will not be of the same class (within the meaning of Rule
144A of the Securities Act) as securities of the Company that are listed on a
national securities exchange registered under Section 6 of the Securities
Exchange Act of 1934, as amended (the "EXCHANGE ACT") or that are quoted in a
United States automated inter-dealer quotation system.

         (dd) (i) None of the Company or any of its "affiliates" (as such term
is defined in Rule 501(b) under the Securities Act) or any person acting on
behalf of any such person (excluding the Initial Purchasers and their respective
affiliates, as to whom this representation shall not apply) has engaged in any
directed selling efforts (as such term is defined in Regulation S) in the United
States with respect to the Notes, and (ii) each of the 


                                      10

<PAGE>

Company, its affiliates and each person acting on behalf of any of them 
(other than the Initial Purchasers and their respective affiliates, as to 
which no representation made) has complied with the offering restrictions 
requirement of Regulation S.

         (ee) None of the Company or any of its affiliates or any person acting
on behalf of any of them (excluding the Initial Purchasers and their respective
affiliates, as to whom this representation shall not apply) has sold, offered
for sale, solicited offers to buy or otherwise negotiated in respect of any
security (as such term is defined in the Securities Act) that is or may be
integrated with the sale of the Notes in a manner that would require
registration under the Securities Act.

and is in compliance in all material respects with the provisions of such
section.

         (gg) Subject to (i) compliance by the Initial Purchasers with the
procedures set forth in Section 3 hereof, (ii) the accuracy of the
representations and warranties of the Initial Purchasers in Section 3 hereof,

this Agreement and the Offering Circular by purchasers to whom the Initial
Purchasers initially resell Notes, and (iv) receipt by the purchasers to whom
the Initial Purchasers initially resell Notes of a copy of the Offering Circular
prior to such resale, it is not necessary, in connection with the offer, sale
and delivery of the Notes to the Initial Purchasers in the manner contemplated
by this Agreement and the Offering Circular, to register the Notes under the
Securities Act or to qualify the Indenture under the Trust Indenture Act of
1939, as amended.

         (hh) The shares of Common Stock issuable upon conversion of the Notes
have been duly authorized and, when issued in accordance with the terms of the
Notes and the Indenture, will be validly issued, fully paid and nonassessable
and will conform in all material respects to the description thereof contained
in the Offering Circular.  The shares of Common Stock issuable on conversion of
the Notes at the initial conversion price set forth in the Indenture have been
reserved for issuance and no further approval or authority of the shareholders
or the Board of Directors of the Company will be required for such issuance of
Common Stock.

         (ii) The Company is not, and upon consummation of the transactions
contemplated hereby will not be, subject to registration as an "investment
company" under the Investment Company Act of 1940, as amended.

         (jj) The execution and delivery of this Agreement and the other
Transaction Agreements will not result in any prohibited transaction within the
meaning of

<PAGE>

Section 406 of ERISA or Section 4975 of the Internal Revenue Code of 1986, as 
amended.  No employee benefit plan (as defined in Section 3(3) of ERISA) will 
be an obligor with respect to the Notes after taking into account the 
applicability, if at all, of Labor Regulation Section 2510.3-101.

         (kk) None of the execution, delivery and performance of this
Agreement, the issuance and sale of the Notes, the application of the proceeds
from the issuance and sale of the Notes and the consummation of the transactions
contemplated thereby as set forth in the Offering Circular, will violate
Regulations G, T, U or X promulgated by the Board of Governors of the Federal
Reserve System or analogous foreign laws and regulations.

         2.   PURCHASE, SALE AND DELIVERY OF THE NOTES.

         (a)  On the basis of the representations, warranties, covenants and
agreements herein contained, but subject to the terms and conditions herein set
forth, the Company agrees to sell to the Initial Purchasers, and the Initial
Purchasers, severally and not jointly, agree to purchase from the Company, the
principal amount of the Firm Notes set forth opposite their respective names in
Schedule I hereto at a purchase price equal to 100% of such principal amount
LESS a discount of 2.825% of such principal amount.  Payment of the purchase
price for, and delivery of, the Firm Notes will be made at the offices of Haynes
and Boone, LLP, 3100 NationsBank Plaza, 901 Main Street, Dallas, Texas 
75202-3789, at 8:00 a.m. (Dallas time) on October 14, 1997, unless postponed 
in accordance with Section 9 hereof, or at such other place, time and date as 
may be mutually agreed in writing between the Representative and the Company 
(the time and date of such payment and delivery being herein called the 
"CLOSING DATE").

         (b)  In addition, on the basis of the representations, warranties,
covenants and agreements herein contained, but subject to the terms and
conditions herein set forth, the Company hereby grants to the Initial Purchasers
the option to purchase, severally and not jointly, up to $20,000,000 aggregate
principal amount of Optional Notes, for the sole purpose of covering 
over-allotments in the sale of Firm Notes by the Initial Purchasers, at the 
same purchase price to be paid by the Initial Purchasers to the Company for 
the Firm Notes as set forth in Section 2(a).  This option may be exercised, 
in whole or in part, at any time and from time to time on or before the 30th 
day following the date of the Offering Circular, by written notice to the 
Company by the Representative on behalf of the Initial Purchasers.  Such 
notice shall set forth the aggregate principal amount of Optional Notes to be 
purchased pursuant to such exercise of the option and the date and time, as 
reasonably determined by the Representative, when the Optional Notes are to 
be delivered (each such date and time being herein sometimes referred to as 
an "ADDITIONAL CLOSING DATE"); 


                                      12

<PAGE>

PROVIDED that no additional Closing Date shall be earlier than (i) the 
Closing Date or (ii) the second full business day after the date on which the 
option shall have been exercised, nor later than the eighth full business day 
after the date on which the option shall have been exercised (unless such 
date and time are postponed in accordance with Section 9 hereof).  The 
principal amount of the Optional Notes to be purchased by each Initial 
Purchaser upon such exercise shall bear the same ratio to the aggregate 
principal amount of Optional Notes being purchased upon such exercise as the 
principal amount of Firm Notes set forth opposite the name of such Initial 
Purchaser in Schedule I hereto (or such number increased as set forth in 
Section 9 hereof) bears to the aggregate principal amount of Firm Notes, 
subject to such adjustments to eliminate fractional amounts as the 
Representative in its sole discretion may make.

         (c)  At or prior to the Closing Date and the Additional Closing Date
(if any) hereunder, the Company shall execute and deliver for authentication the
Notes to be purchased and sold on such date and shall deposit such Notes with
The Depositary Trust Company ("DTC") for the account or accounts of participants
in DTC (including Euroclear and CEDEL, as the case may be) purchasing beneficial
interests therein.  The Initial Purchasers shall pay or cause the purchase price
for such Notes to be paid to or upon the order of the Company by wire transfer
of same day funds against delivery of such Notes to or for the respective
accounts of the Initial Purchasers.  Certificates evidencing the Notes shall be
registered in the name of Cede & Co. as nominee for DTC or such other name or
names and in such authorized denominations as the Representative may request in
writing at least two full business days prior to the Closing Date or the
Additional Closing Date, as the case may be.  The Company will permit the
Representative to inspect such certificates at the offices of the Representative
at least one full business day prior to the Closing Date and the Additional
Closing Date, if any.

         3.   SUBSEQUENT OFFERS AND RESALES OF THE NOTES.  The Initial
Purchasers and the Company hereby establish and agree to observe the following
procedures in connection with the offer and sale of the Notes:

Offering Circular.  Except as contemplated by the Registration Rights Agreement,
the Notes have not been and will not be registered under the Securities Act. 
Each Initial Purchaser agrees that neither it nor any of its affiliates nor any
person acting on behalf of it or any such affiliate will take, and acknowledges
that the Company has not taken, any action that would constitute a public
offering of the Notes in any jurisdiction and further agrees that, with respect
to the offer or sale of any Notes or the delivery or distribution of any
Offering 


                                      13

with the offer or sale of the Notes.

         (c)  In connection with sales outside the United States, each Initial
Purchaser agrees that it will not offer, sell or deliver Notes (i) as part of
the distribution thereof at any time or (ii) otherwise until 40 days (subject to
extension as required by Regulation S in the event that Regulation S is amended
and such amendment is deemed applicable to the Notes) (the "RESTRICTED PERIOD")
after completion of the distribution, as determined by the Representative, to or
for the account or benefit of U.S. Persons (as defined in Regulation S).  Each
Initial Purchaser confirms that neither it nor any of its affiliates nor any
person acting on behalf of it or any such affiliate has engaged, and agrees that
neither it nor any of its affiliates will engage, in any "directed selling
efforts" (as such term is defined in Regulation S) with respect to the Notes or
the underlying Common Stock and that it, its affiliates and each such other
person has complied and will comply with the offering restrictions required by
Regulation S with respect to the Notes and the underlying Common Stock.

         (d)  Each of the Initial Purchasers acknowledges and agrees that it
has not and will not offer, sell or deliver the Notes in the United States or to

Regulation S), (ii) institutional buyers that are reasonably believed to be QIBs
and (iii) purchasers that are reasonably believed by the Initial Purchasers to
be Institutional Accredited Investors and that have executed and delivered to
the Representative a letter in the form of Annex A to the Offering Circular.

         (e)  Each Initial Purchaser agrees that, at or prior to confirmation
of a sale of Notes (other than a sale pursuant to Rule 144A), it will send to
each distributor, dealer or person receiving a selling concession, fee or other
remuneration that purchases Notes from the Initial Purchasers during the
Restricted Period a confirmation or notice to substantially the following
effect:

              "The Notes covered hereby have not been registered
              under the United States Securities Act of 1933, as amended
              (the "Securities Act") and may not be offered or sold within

<PAGE>

              the United States or to, or for the account or benefit of,
              "U.S. persons" (as defined in Regulation S under the
              Securities Act ("Regulation S")) (i) as part of their
              distribution at any time or (ii) otherwise until 40 days
              (subject to extension as required by Regulation S in the
              event that Regulation S is amended and such amendment is
              deemed applicable to the Notes) after the later of [the
              commencement of the offering of the Notes] and the [closing
              date], except in either case, for sales made (i) in
              accordance with Regulation S; (ii) to institutional buyers
              that are reasonably believed to be "qualified institutional
              buyers," as defined in, and in accordance with, Rule 144A
              under the Securities Act; or (iii) to purchasers that are
              reasonably believed to be institutional "accredited
              investors" as defined in Rule 501(a)(1), (2), (3) and (7) of
              Regulation D under the Securities Act."

         (f)  Each Initial Purchaser represents, warrants and agrees that (i)
it has not offered or sold and will not offer or sell Notes in the United
Kingdom, other than to persons whose ordinary activities involve them in
acquiring, holding, managing or disposing of investments (whether as principal
or agent) for the purposes of their businesses or otherwise in circumstances
that will not result in an offer to the public within the meaning of the Public
Offers of Securities Regulations 1995, (ii) it has complied and will comply with
all applicable provisions of the Public Offers of Securities Regulations 1995
and the Financial Services Act of 1986 with respect to anything done by it in
relation to the Notes in, from or otherwise involving the United Kingdom, and
(iii) it has only issued or passed on, and will only issue or pass on, to any
person in the United Kingdom any documents received by it in connection with the
issue of the Notes if the person is of a kind described in Article 11(c) of the
Financial Services Act of 1986 (Investment Advertisements) (Exemptions) Order
1988 or is a person to whom the documents may lawfully be issued or passed on. 
Each Initial Purchaser further agrees that it will not offer or sell any Notes
directly or indirectly in Japan or to any resident of Japan except (i) pursuant
to an exemption from the registration requirements of the Securities and
Exchange Law of Japan and (ii) in compliance with any applicable requirements of
Japanese law.  Each Initial Purchaser further agrees that it will not offer or
sell any Notes directly or indirectly in any province of Canada except in
compliance with all requirements of applicable securities laws and that it will

Closing Date, if any, any event shall have occurred as a result of which the
Offering Circular as then amended or supplemented would in the reasonable
judgment of the Initial Purchasers or the Company include 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 the light of the circumstances
under which they were made, not misleading, the Company will notify the
Representative promptly and prepare and deliver to the Representative on behalf
of the Initial Purchasers an amendment or supplement (in form and substance
satisfactory to the Initial Purchasers) which will correct such statement or

Company shall not be required in connection therewith to register or qualify as
a foreign corporation in any jurisdiction where it is not now so qualified or to
take any action that would subject it to general service of process or taxation,
or to take action, in each case, in any jurisdiction where it is not now so
subject.

         (c)  The Company will promptly deliver to the Initial Purchasers such
number of copies of the Offering Circular and all amendments thereof and
supplements thereto as the Representative reasonably may request.

rules and regulations of the National Association of Securities Dealers, Inc.,
relating to trading in the PORTAL Market.

         (f)  For a period of 90 days from the date of this Agreement, the
Company will not offer to sell, issue, sell, contract to sell, grant any option
for the sale of, or otherwise dispose of, directly or indirectly, any shares of
Common Stock or any securities convertible into or exchangeable or exercisable
for Common Stock (other than the Notes and other than pursuant to the exercise
of outstanding options and warrants, grants of options in the ordinary course of
business, and issuances in connection with acquisitions) or any rights to
acquire Common Stock, without the prior written consent of the Representative. 
In addition, the Company will obtain and deliver to the Representative

         (g)  So long as any of the Notes are "restricted securities" within
the meaning of Rule 144(a)(3) under the Securities Act, the Company will provide
to any holder of the Notes or to any prospective purchaser of the Notes
designated by any holder, upon request of such holder or prospective purchaser,
information required to be provided by Rule 144A(d)(4) of the Securities Act if
at the time of such request, the Company is not subject to the reporting
requirements under Section 13 or 15(d) of the Exchange Act.

         (h)  Except following the effectiveness of the Registration Statement,
None of the Company, its subsidiaries, its affiliates or any person acting on
behalf of any of them (other than the Initial Purchasers and their respective
affiliates, as to whom this undertaking by the Company shall not be deemed to
apply) will solicit any offer to buy or offer or sell the Notes by means of any
form of general solicitation or general advertising (as those terms are used in
Regulation D under the Securities Act) or in any manner involving a public
offering within the meaning of the Securities Act.

         (i)  None of the Company, its subsidiaries, its affiliates or any
person acting on behalf of any of them (other than the Initial Purchasers and
their respective affiliates, as to whom this undertaking by the Company shall
not be deemed to apply) will offer to sell, sell or solicit offers to buy or
otherwise negotiate in respect of the sale of any security (as defined in the
Securities Act) that would be integrated with the sale of the Notes so as to
require the registration of the Notes under the Securities Act.

         (j)  During the period of two years from and after the Closing Date,
none of the Company, its subsidiaries or its or their affiliates will resell any
Notes that may have been purchased or otherwise acquired by them, except in a

         (b)  At the Closing Date, the Initial Purchasers shall have received 
the opinion of Haynes and Boone, LLP, counsel for the Company, dated the 
Closing Date, addressed to the Initial Purchasers and in form and scope 
reasonably satisfactory to Weil, Gotshal & Manges LLP ("COUNSEL FOR THE 
INITIAL PURCHASERS"), to the effect that:

                 (i)  The Company and each Significant Subsidiary, other than

     full corporate power and authority to own, lease and operate its properties
     and conduct its business as described in the Offering Circular.

                (ii)  The Partnership has been duly organized and is validly

     contained in the Offering Circular under the heading "Description of
     Capital Stock."  The outstanding shares of the Company's Common Stock have
     been duly authorized and validly issued and are fully paid and
     nonassessable.  The shares of Common Stock initially issuable upon
     conversion of the Notes have been duly authorized and reserved for issuance
     upon such conversion and, when issued and delivered upon such conversion in
     accordance with the provisions of the Indenture (assuming payment for and
     delivery of the Notes in accordance with this Agreement), will be validly
     issued, fully paid and nonassessable and no further approval or authority
     of the shareholders or the Board of Directors of the Company will be
     required for such issuance.

                (iv)  Except as disclosed in the Offering Circular and any
     document incorporated by reference therein, and except for stock options
     outstanding under the Company's existing stock option plans, to the
     knowledge of such counsel there are no outstanding options, warrants or
     other rights calling for the issuance of, and no commitments or obligations
     on the part of the Company to issue, any shares of capital stock of the
     Company or any security convertible into or exchangeable for capital stock
     of the Company.

                                      20
<PAGE>

                 (v)  Except for those rights which have been waived in
     connection with the transactions contemplated by this Agreement, there are
     no preemptive rights to subscribe for or purchase shares of the Company's
     Common Stock provided in the Company's charter or bylaws or, to the
     knowledge of such counsel, in any agreement to which the Company is a
     party.

                (vi)  The Company has all requisite corporate power and
     authority to execute, deliver and perform its obligations under this
     Agreement and each of the other Transaction Agreements to which it is a
     party and to consummate the transactions contemplated thereby, including,
     without limitation, the corporate power and authority to issue, sell and
     deliver the Notes as provided herein.

     delivered by the Company.

              (viii)  The Indenture has been duly authorized, executed and
     delivered by the Company and, assuming due authorization, execution and
     delivery thereof by the Trustee, constitutes the legal, valid and binding
     obligation of the Company, enforceable against the Company in accordance
     with its terms, subject to applicable bankruptcy, insolvency, fraudulent
     conveyance, fraudulent transfer, reorganization, moratorium and similar
     laws affecting creditors' rights and remedies generally, and subject, as to
     enforceability, to general principles of equity, including principles of
     commercial reasonableness, good faith and fair dealing (regardless of
     whether enforcement is sought in a proceeding in equity or at law).

                (ix)  The Notes have been duly authorized, executed and
     issued by the Company and, assuming due authentication thereof by the
     Trustee, upon payment therefor and delivery thereof in accordance with this
     Agreement and the Indenture, will constitute the legal, valid and binding
     obligations of the Company enforceable against the Company in accordance
     with their terms and will be entitled to the benefits of the Indenture,
     subject to applicable bankruptcy, insolvency, fraudulent conveyance,
     fraudulent transfer, reorganization, moratorium and similar laws affecting
     creditors' rights and remedies generally, and subject, as to
     enforceability, to general principles of equity, including principles of
     commercial reasonableness, good faith and fair dealing (regardless of
     whether enforcement is sought in a proceeding in equity or at law).

                 (x)  The Registration Rights Agreement has been duly 
     authorized, executed and delivered by the Company and, assuming due
     authorization, execution and delivery thereof by the Initial Purchasers,
     constitutes the legal, valid 

                                      21
<PAGE>

     and binding obligation of the Company enforceable against the Company in 
     accordance with its terms, subject to applicable bankruptcy, insolvency, 
     fraudulent conveyance, fraudulent transfer, reorganization, moratorium and 
     similar laws affecting creditors' rights and remedies generally, and 
     subject, as to enforceability, to general principles of equity, including 
     principles of commercial reasonableness, good faith and fair dealing 
     (regardless of whether enforcement is sought in a proceeding in equity or 
     at law) and except as the enforceability of rights to indemnification 
     thereunder may be limited by federal or state securities laws or public 
     policy relating thereto and the right of a Holder to receive Liquidated 
     Damages may be limited to the amount of actual damages suffered by such 
     Holder.

                (xi)  The Notes, the Indenture and the Registration Rights
     Agreement conform as to legal matters in all material respects to the
     descriptions thereof contained in the Offering Circular.

               (xii)  The issue and sale of the Notes by the Company and the
     compliance by the Company with all of the provisions of this Agreement and
     the Registration Rights Agreement will not conflict with, violate the terms
     of or result in a default under any indenture, mortgage, deed of trust,
     loan agreement or other agreement or instrument filed or incorporated by
     reference as an exhibit to the Company's Annual Report on Form 10-K for the
     year ended November 30, 1996 (the "1996 FORM 10-K"), or its Quarterly
     Reports on Form 10-Q for the quarters ended February 28, 1997, May 31, 1997
     and August 31, 1997 or any material agreement entered into by the Company
     subsequent to August 31, 1997 of which such counsel has knowledge, except
     for conflicts, violations or defaults which have been waived, nor will such
     action violate the charter or bylaws of the Company or any federal or,
     solely with respect to the General Corporation Law of the State of
     Delaware, Delaware statute, rule or regulation applicable to the Company or
     violate any order known to such counsel issued by any governmental agency
     or body or court having jurisdiction over the Company or any of its
     subsidiaries or any of its or their respective properties.

              (xiii)  Except as have been obtained or made, no consent,
     approval, authorization, order, registration or qualification of or with
     any federal or, solely with respect to the General Corporation Law of the
     State of Delaware, Delaware governmental agency or body is required for the
     issue and sale of the Notes and the underlying Common Stock by the Company
     and compliance by the Company with the provisions of this Agreement and the
     Registration Rights Agreement, except for the registration of the Notes
     under the Securities Act (as to which no opinion is expressed in this
     paragraph) and qualification of the Indenture under the Trust 

                                      22
<PAGE>

     Indenture Act (as to which no opinion is expressed in this paragraph), and 
     such consents, approvals, authorizations, registrations or qualifications 
     as may be required under state securities or Blue Sky laws or the 
     securities laws of any jurisdiction outside the United States in connection
     with the purchase and resale of the Notes by the Initial Purchasers (as to 
     which no opinion is expressed).

               (xiv)  The statements made in the Offering Circular under the
     heading "Certain Tax Considerations," insofar as they purport to constitute
     summaries of matters of United States federal tax law and regulations or
     legal conclusions with respect thereto, constitute accurate summaries of
     the matters described therein in all material respects.

                (xv)  No registration under the Securities Act of the Notes
     or the shares of Common Stock issuable upon conversion of the Notes in
     accordance with the Indenture, and no qualification of the Indenture under
     the Trust Indenture Act of 1939, as amended, is required for the offer and
     sale of the Notes by the Company to the Initial Purchasers or the initial
     reoffer and resale of the Notes by the Initial Purchasers solely in the
     manner contemplated by the Offering Circular and this Agreement.

               (xvi)  Except as disclosed in the Offering Circular, to the
     knowledge of such counsel, no holders of securities of the Company have
     rights to require the registration of such securities because of the filing
     by the Company of the Shelf Registration Statement (as such term is defined
     in the Offering Circular) except such as have been validly waived.

              (xvii)  When the Notes are issued and delivered pursuant to
     this Agreement, no Notes will be of the same class (within the meaning of
     Rule 144A under the Act) as securities of the Company that are listed on a
     national securities exchange registered under Section 6 of the Exchange Act
     or that are quoted in a United States automated inter-dealer quotation
     system.

             (xviii)  Assuming the proceeds from the Offering are applied as
     described in the Offering Circular, none of the execution, delivery and
     performance of this Agreement, the issuance and sale of the Notes, the
     application of the proceeds from the issuance and sale of the Notes and the
     consummation of the transactions contemplated thereby as set forth in the
     Offering Circular, will violate Regulations G, T, U or X promulgated by the
     Board of Governors of the Federal Reserve System.

                                      23

In addition, such counsel shall state that such counsel has participated in 
conferences with officers and other representatives of the Company, 
representatives of the independent public accountants for the Company, 
representatives of the Initial Purchasers and Counsel for the Initial 
Purchasers at which the contents of the Offering Circular and related matters 
were discussed and, although such counsel did not independently verify such 
information and is not passing upon and does not assume any responsibility 
for the accuracy, completeness or fairness of the statements contained in the 
Offering Circular, on the basis of the foregoing (relying as to the factual 
matters upon the statements of officers and other representatives of the 
Company and public officials) no facts have come to such counsel's attention 
that caused such counsel to believe that the Offering Circular (other than 
the financial statements and notes thereto and other financial and accounting 
data included or incorporated by reference therein, or omitted therefrom, as 
to which such counsel need express no belief) at the date of the Offering 
Circular and as of the Closing Date contained or contains an untrue statement 
of a material fact or omitted or omits to state a material fact required to 
be stated therein or necessary to make the statements therein, in light of 
the circumstances under which they were made, not misleading.

         In rendering such opinion, such counsel may rely (x) as to matters 
involving the application of laws other than the laws of the United States 
and jurisdictions in which such counsel are admitted, to the extent such 
counsel may deem proper and to the extent specified in such opinion, if at 
all, upon an opinion or opinions (in form and substance reasonably 
satisfactory to Counsel for the Initial Purchasers) of other counsel, 
reasonably acceptable to Counsel for the Initial Purchasers, familiar with 
the applicable laws (it being understood, however, that with respect to the 
validity, binding effect and enforceability of the Indenture, the Notes and 
the Registration Rights Agreement, counsel may opine as if such instruments 
were governed by the laws of the State of Texas) and (y) as to matters of 
fact, to the extent they deem proper, on the representations and warranties 
of the Company and the Initial Purchasers contained herein, on certificates 
of responsible officers of the Company and certificates or other written 
statements of officers of departments of various jurisdictions having custody 
of documents respecting the corporate existence or good standing of the 
Company and its subsidiaries.

         (c)  All proceedings taken in connection with the sale of the Notes 
as herein contemplated shall be reasonably satisfactory in form and substance 
to the Initial Purchasers and to Counsel for the Initial Purchasers, and the 
Initial Purchasers shall have received from said Counsel for the Initial 
Purchasers a favorable opinion, dated as of the Closing Date with respect to 
the issuance and sale of the Notes, the Offering Circular and such other 
related matters as the Initial Purchasers may reasonably require, and the 
Company shall have furnished to Counsel for the Initial Purchasers such 
documents as they reasonably may request for the purpose of enabling them to 
pass upon such matters.

                                      24
<PAGE>

         (d)  At the Closing Date, the Initial Purchasers shall have received 
a certificate of the Chief Executive Officer and Chief Financial Officer of 
the Company, dated the Closing Date, to the effect that (i) as of the date 
hereof and as of the Closing Date, the representations and warranties of the 
Company set forth in Section 1 hereof are accurate in all material respects, 
(ii) as of the Closing Date, the obligations of the Company to be performed 
hereunder on or prior thereto have been duly performed in all material 
respects and (iii) subsequent to the respective dates as of which information 
is given in the Offering Circular, the Company and its subsidiaries have not 
sustained any material loss or interference with their respective businesses 
or properties from fire, flood, hurricane, accident or other calamity, 
whether or not covered by insurance, or from any labor dispute or any legal 
or governmental proceeding, and there has not been any material adverse 
change, or any development involving a material adverse change in the 
business, properties, operations, condition (financial or otherwise), or 
results of operations of the Company and its subsidiaries taken as a whole, 
except in each case as disclosed in the Offering Circular.

         (e)  At the time this Agreement is executed and at the Closing Date, 
the Initial Purchasers shall have received a letter from KPMG Peat Marwick 
LLP, independent accountants for the Company, dated, respectively, as of the 
date of this Agreement and as of the Closing Date and addressed to the 
Initial Purchasers, in form, scope and substance as shall have been 
previously agreed to by the Representative.

         (f)  Prior to the Closing Date, the Company shall have furnished to 
the Initial Purchasers such further information, certificates and documents 
as the Initial Purchasers may reasonably request.

         (g)  The Company shall have entered into the Indenture and the 
Registration Rights Agreement and the Initial Purchasers shall have received 
counterparts, conformed and executed, thereof.

         (h)  The Initial Purchasers shall have received from each person who 
is a director or executive officer (as defined in the proxy rules of the 
Securities and Exchange Commission) of the Company an agreement to the effect 
that during the period of 90 days from the date of the Offering Circular, 
such person will not, directly or indirectly, without the prior written 
consent of the Representative, offer to sell, sell, contract to sell, grant 
any option or rights to acquire or purchase any option to sell, or otherwise 
dispose of, any shares of Common Stock; PROVIDED, HOWEVER, that the foregoing 
restrictions shall not apply with respect to approximately 38,500 shares of 
Common Stock upon the exercise of certain employee stock options held by 
Michael Hedge, Richard White and A.S. Horng.  

                                      25
<PAGE>

         (i)  At the Closing Date, the Notes shall have been approved for 
quotation in the PORTAL Market.

         (j) Prior to the Closing Date, the Company shall have filed the 
Third Quarter Form 10-Q in substantially the same form as provided to the 
Initial Purchasers prior to the execution of this Agreement.

         If any of the conditions specified in this Section 6 shall not have 
been fulfilled in all material respects when and as required by this 
Agreement, or if any of the certificates, opinions, written statements or 
letters furnished to the Initial Purchasers or to Counsel for the Initial 
Purchasers pursuant to this Section 6 shall not be in all material respects 
reasonably satisfactory in form and scope to the Representative and to 
Counsel for the Initial Purchasers, all obligations of the Initial Purchasers 
hereunder may be canceled by the Representative at, or at any time prior to, 
the Closing Date and the obligations of the Initial Purchasers to purchase 
the Optional Notes may be canceled by the Representative at, or at any time 
prior to, the Additional Closing Date.  Notice of such cancellation shall be 
given to the Company in writing, or by telephone, telex or telegraph, 
confirmed in writing.

         7.   INDEMNIFICATION.

         (a)  The Company agrees to indemnify and hold harmless each Initial 
Purchaser and each person, if any, who controls any Initial Purchaser within 
the meaning of Section 15 of the Securities Act or Section 20(a) of the 
Securities Exchange Act of 1934, as amended (the "Exchange Act"), against any 
and all losses, liabilities, claims, damages and expenses whatsoever as 
incurred (including but not limited to reasonable attorneys' fees and 
expenses whatsoever incurred in investigating, preparing or defending against 
any litigation, commenced or threatened, or any claim whatsoever, and any and 
all amounts paid in settlement of any claim or litigation) (collectively, 
"LOSSES"), joint or several, to which they or any of them may become subject 
under the Securities Act, the Exchange Act or otherwise, insofar as such 
Losses (or actions in respect thereof) arise out of or are based upon any 
untrue statement or alleged untrue statement of a material fact contained in 
the Offering Circular or any related Preliminary Offering Circular or any 
amendment or supplement thereto 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, in light of the 
circumstances under which they were made, not misleading; PROVIDED, HOWEVER, 
that the Company will not be liable in any such case to the extent but only 
to the extent that any such Losses arise out of or are based upon any such 
untrue statement or alleged untrue statement or omission or alleged omission 
made therein in reliance upon and in conformity with written information 
furnished to the Company by 

                                      26
<PAGE>

or on behalf of any Initial Purchaser through the Representative expressly 
for use therein, and PROVIDED FURTHER, that the foregoing indemnity with 
respect to any untrue statement contained in or omission from a Preliminary 
Offering Circular or the Offering Circular shall not inure to the benefit of 
any Initial Purchaser (or any person controlling such Initial Purchaser) from 
whom the person asserting any such loss, liability, claim, damage or expense 
purchased any of the Notes if a copy of the Offering Circular (as then 
amended or supplemented if the Company shall have furnished any amendments or 
supplements thereto) was not sent or given by or on behalf of such Initial 
Purchaser to such person at or prior to the written confirmation of the sale 
of such Notes to such person, and if the Offering Circular (as so amended or 
supplemented) would have cured the defect giving rise to such loss, claim, 
damage or liability. This indemnity agreement will be in addition to any 
liability which the Company may otherwise have including under this Agreement.

         (b)  Each Initial Purchaser severally, and not jointly, agrees to 
indemnify and hold harmless the Company, each of the directors of the 
Company, each of the officers of the Company, and each other person, if any, 
who controls the Company within the meaning of Section 15 of the Securities 
Act or Section 20(a) of the Exchange Act, against any Losses whatsoever as 
incurred (including but not limited to reasonable attorneys' fees and any and 
all expenses whatsoever incurred in investigating, preparing or defending 
against any litigation, commenced or threatened, or any claim whatsoever, and 
any and all amounts paid in settlement of any claim or litigation), jointly 
or severally, to which they or any of them may become subject under the 
Securities Act, the Exchange Act or otherwise, insofar as such Losses (or 
actions in respect thereof) arise out of or are based upon any untrue 
statement or alleged untrue statement of a material fact contained in the 
Offering Circular, or any related Preliminary Offering Circular, or in any 
amendment thereof or supplement thereto, 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, in light of 
the circumstances under which they were made, not misleading, in each case to 
the extent, but only to the extent, that any such Losses arise out of or are 
based upon any such untrue statement or alleged untrue statement or omission 
or alleged omission made therein in reliance upon and in conformity with 
written information furnished to the Company by or on behalf of any Initial 
Purchaser through the Representative expressly for use therein; PROVIDED, 
HOWEVER, that in no case shall any Initial Purchaser be liable or responsible 
for any amount in excess of the discount applicable to the Notes purchased by 
such Initial Purchaser hereunder.  This indemnity will be in addition to any 
liability which any Initial Purchaser may otherwise have including under this 
Agreement.  The Company shall only be permitted to seek indemnity pursuant to 
this Section 7(b) or contribution pursuant to Section 8 from the Initial 
Purchasers for the statements set forth in the last paragraph of the cover 
page prior to the paragraph entitled "Special Cautionary Notice Regarding 
Forward Looking Statements" and in the eleventh, 

                                      27
<PAGE>

twelfth and fourteenth paragraphs under the caption "Plan of Distribution" in 
the Offering Circular.

         (c)  Promptly after receipt by an indemnified party under subsection 
(a) or (b) above of notice of the commencement of any action, such 
indemnified party shall, if a claim in respect thereof is to be made against 
the indemnifying party under such subsection, notify each party against whom 
indemnification is to be sought in writing of the commencement thereof (but 
the failure so to notify an indemnifying party shall not relieve it from any 
liability which it may have otherwise than under this Section 7 unless and to 
the extent that it has been prejudiced by such failure or from the forfeiture 
of rights and defenses).  In case any such action is brought against any 
indemnified party, and it notifies an indemnifying party of the commencement 
thereof, the indemnifying party will be entitled to participate therein, and 
to the extent it may elect by written notice delivered to the indemnified 
party promptly after receiving the aforesaid notice from such indemnified 
party, to assume the defense thereof with counsel reasonably satisfactory to 
such indemnified party.  Notwithstanding the foregoing, the indemnified party 
or parties shall have the right to employ its or their own counsel in any 
such case, but the fees and expenses of such counsel shall be at the expense 
of such indemnified party or parties unless (i) the employment of such 
counsel shall have been authorized in writing by one of the indemnifying 
parties in connection with the defense of such action, (ii) the indemnifying 
parties shall not have employed counsel to have charge of the defense of such 
action within a reasonable time after notice of commencement of the action, 
or (iii) such indemnified party or parties shall have reasonably concluded 
that there may be defenses available to it or them which are different from 
or additional to those available to one or all of the indemnifying parties 
(in which case the indemnifying parties shall not have the right to direct 
the defense of such action on behalf of the indemnified party or parties), in 
any of which events such fees and expenses shall be borne by the indemnifying 
parties.  In no event shall the indemnifying party be liable for the fees and 
expenses of more than one counsel in connection with any one such action or 
separate but similar related actions in the same jurisdiction arising out of 
the same general allegations or circumstances.  Anything in this subsection 
to the contrary notwithstanding, an indemnifying party shall not be liable 
for any settlement of any claim or action effected without its written 
consent; PROVIDED, HOWEVER, that such consent was not unreasonably withheld 
or delayed, and the indemnifying party agrees to indemnify and hold harmless 
any indemnified party from and against any Loss by reason of any settlement 
of any action effected with the indemnifying party's written consent.  The 
indemnifying party shall not, without the prior written consent of each 
indemnified party, settle or compromise or consent to the entry of a judgment 
in or otherwise seek to terminate any pending or threatened litigation or 
proceeding in respect of which indemnification or contribution may be sought 
hereunder (whether or not any indemnified party is a party thereto), unless 
such settlement, compromise, consent or 

                                      28
<PAGE>

termination includes an unconditional release of each indemnified party from 
all liability arising out of such action, claim, litigation or proceeding.

         8.   CONTRIBUTION.  In order to provide for contribution in 
circumstances in which the indemnification provided for in Section 7 hereof 
is for any reason held to be unavailable from any indemnifying party, or to 
any indemnified party, or is insufficient to hold harmless a party 
indemnified thereunder, the Company and the Initial Purchasers shall 
contribute to the aggregate losses, claims, damages, liabilities and expenses 
contemplated by such indemnification provision (including any investigation, 
legal and other expenses incurred in connection with, and any amount paid in 
settlement of, any action, suit or proceeding or any claims asserted, but 
after deducting in the case of losses, claims, damages, liabilities and 
expenses suffered by the Company any contribution received by the Company 
from persons, other than the Initial Purchasers, who may also be liable for 
contribution, including persons who control the Company within the meaning of 
Section 15 of the Securities Act or Section 20(a) of the Exchange Act, 
officers and directors of the Company) as incurred to which the Company and 
one or more of the Initial Purchasers may be subject, in such proportions as 
is appropriate to reflect the relative benefits received by the Company and 
the Initial Purchasers from the offering of the Notes or, if such allocation 
is not permitted by applicable law, in such proportion as is appropriate to 
reflect not only the relative benefits referred to above but also the 
relative fault of the Company and the Initial Purchasers in connection with 
the statements or omissions which resulted in such losses, claims, damages, 
liabilities or expenses, as well as any other relevant equitable 
considerations.  The relative benefits received by the Company and the 
Initial Purchasers shall be deemed to be in the same proportion as (x) the 
total proceeds from the offering (net of underwriting discounts and 
commissions but before deducting expenses) received by the Company and (y) 
the underwriting discounts and commissions received by the Initial Purchasers 
respectively.  The relative fault of the Company and of the Initial 
Purchasers shall be determined by reference to, among other things, whether 
the untrue or alleged untrue statement of a material fact or the omission or 
alleged omission to state a material fact relates to information supplied by 
the Company or the Initial Purchasers and the parties' relative intent, 
knowledge, access to information and opportunity to correct or prevent such 
statement or omission.  The Company and the Initial Purchasers agree that it 
would not be just and equitable if contribution pursuant to this Section 8 
were determined by pro rata allocation (even if the Initial Purchasers were 
treated as one entity for such purpose) or by any other method of allocation 
which does not take account of the equitable considerations referred to 
above.  Notwithstanding the provisions of this Section 8, (i) in no case 
shall any Initial Purchaser be liable or responsible for any amount in excess 
of the discount applicable to the Notes purchased by such Initial Purchaser 
hereunder, (ii) 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 

                                      29
<PAGE>

fraudulent misrepresentation and (iii) no Initial Purchaser shall be required 
to contribute any amount in excess of the amount by which the total price at 
which the Note purchased by it and sold in the Offering were offered to 
subsequent purchasers exceeds the amount of any damages that such Initial 
Purchaser has otherwise been required to pay by reason of such untrue or 
alleged untrue statement or omission or alleged omission.  For purposes of 
this Section 8, each person, if any, who controls an Initial Purchaser within 
the meaning of Section 15 of the Securities Act or Section 20(a) of the 
Exchange Act shall have the same rights to contribution as such Initial 
Purchaser, and each person, if any, who controls the Company within the 
meaning of Section 15 of the Securities Act or Section 20(a) of the Exchange 
Act, each officer and each director of the Company shall have the same rights 
to contribution as the Company, subject in each case to clauses (i) and (ii) 
of this Section 8.  Any party entitled to contribution will, promptly after 
receipt of notice of commencement of any action, suit or proceeding against 
such party in respect of which a claim for contribution may be made against 
another party or parties, notify each party or parties from whom contribution 
may be sought, but the omission to so notify such party or parties shall not 
relieve the party or parties from whom contribution may be sought from any 
obligation it or they may have under this Section 8 or otherwise.  No party 
shall be liable for contribution with respect to any action or claim settled 
without its consent; PROVIDED, HOWEVER, that such consent was not 
unreasonably withheld.

         9.   DEFAULT BY AN INITIAL PURCHASER.  If any of the Initial 
Purchasers shall fail at the Closing Date or Additional Closing Date to 
purchase the Notes which it is obligated to purchase under this Agreement 
(the "DEFAULTED NOTES"), the non-defaulting Initial Purchaser shall have the 
right, within 24 hours thereafter, to make arrangements for it to purchase 
all, but not less than all, of the Defaulted Notes upon the terms herein set 
forth; PROVIDED, HOWEVER, that if the non-defaulting Initial Purchaser shall 
not have completed such arrangements within such 24-hour period, then, upon 
the expiration of such 24-hour period, this Agreement shall terminate without 
liability on the part of the non-defaulting Initial Purchaser.

         No action taken pursuant to this Section shall relieve the 
defaulting Initial Purchaser from liability in respect of its default.

         In the event of any such default which does not result in a 
termination of this Agreement, either the non-defaulting Initial Purchaser or 
the Company shall have the right to postpone the Closing Date for a period 
not exceeding seven days in order to effect any required changes in the 
Offering Circular or in any other documents or arrangements.

         10.  SURVIVAL OF REPRESENTATIONS AND AGREEMENTS.  All 
representations and warranties, covenants and agreements of the Initial 
Purchasers and the Company 

                                      30
<PAGE>

contained in this Agreement, including the agreements contained in Section 5, 
the indemnity agreements contained in Section 7 and the contribution 
agreements contained in Section 8, shall remain operative and in full force 
and effect regardless of any investigation made by or on behalf of any 
Initial Purchasers or any agent, representative or controlling person thereof 
or by or on behalf of the Company, any of its officers and directors or any 
controlling person thereof, and shall survive delivery of and payment for the 
Notes to and by the Initial Purchasers.  The agreements contained in Sections 
5, 7, 8 and 11(c) hereof shall survive the termination of this Agreement, 
including termination pursuant to Section 9 or 11 hereof.

         11.  TERMINATION.

         (a)  The Representative shall have the right to terminate this 
Agreement at any time prior to the Closing Date or the obligations of the 
Initial Purchasers to purchase the Optional Notes at any time prior to the 
Additional Closing Date, as the case may be, if (i) any domestic or 
international event, act or occurrence shall have materially disrupted, or in 
the Representative's reasonable opinion will in the immediate future 
materially disrupt, the United States or international securities markets; or 
(ii) trading on the New York Stock Exchange shall have been suspended, or 
materially limited; or (iii) a banking moratorium shall have been declared by 
any United States federal or New York or Texas state authority or if any new 
restriction materially adversely affecting the distribution of the Firm Notes 
or the Optional Notes, as the case may be, shall have become effective; or 
(iv) any "nationally recognized statistical rating organization" (as defined 
for purposes of Rule 436(g) under the Securities Act) shall have announced 
that it is (A) downgrading its rating assigned to any class of the Company's 
debt securities or (B) reviewing any such rating with a view to possible 
downgrading or with negative implications; or (v) there shall have occurred 
any outbreak or escalation of hostilities involving the United States, or a 
declaration of war or national emergency by the United States, or any change 
in political, financial or economic conditions the effect of which is such, 
in the judgment of the Representative, to make it impracticable or 
inadvisable to proceed with the offering, sale and delivery of the Firm Notes 
or the Optional Notes, as the case may be, on the terms contemplated by the 
Offering Circular.

         (b)  Any notice of termination pursuant to this Section 11 shall be 
by telephone, telex, or telegraph, confirmed in writing by letter.

         (c)  If this Agreement shall be terminated pursuant to any of the 
provisions hereof (other than pursuant to Section 9 or 11(a) hereof), or if 
the sale of the Notes provided for herein is not consummated because any 
condition to the obligations of the Initial Purchasers set forth herein is 
not satisfied or because of any refusal, inability or 

                                      31
<PAGE>

failure on the part of the Company to perform any agreement herein or comply 
with any provision hereof, the Company will, upon demand by the 
Representative, reimburse the Initial Purchasers for all reasonable 
out-of-pocket expenses (including the reasonable fees and expenses of Counsel 
for the Initial Purchasers), incurred by the Initial Purchasers solely and 
directly in connection with the transactions contemplated by this Agreement, 
and thereafter the Company shall have no further liability to the Initial 
Purchaser.

         12.  NOTICE.  All communications hereunder, except as may be 
otherwise specifically provided herein, shall be in writing and shall be 
mailed, delivered, or telexed or telegraphed and confirmed in writing, (i) if 
to any of the Initial Purchasers, to such Initial Purchaser in care of Bear, 
Stearns & Co. Inc., 300 Crescent Court, Suite 200, Dallas, Texas 75201,

         13.  PARTIES.  This Agreement shall inure solely to the benefit of, 
and shall be binding upon, the Initial Purchasers and the Company and their 
respective successors and assigns, and no other person shall have or be 
deemed to have any legal or equitable right, remedy or claim under or in 
respect of or by virtue of this Agreement or any provision hereof.  The term 
"successors and assigns" shall not include a purchaser, in its capacity as 
such, of Notes from any of the Initial Purchasers.

         14.  GOVERNING LAW.  This Agreement shall be governed by the laws of 
the State of New York.

         15.  CAPTIONS.  The captions included in this Agreement are included

Global Notes or for definitive Notes only in accordance with the requirements
described in Section 2.5 below.

    Any of the Notes may have such letters, numbers or other marks of
identification and such notations, legends and endorsements as the officers
executing the same may approve (execution thereof to be conclusive evidence of
such approval) and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Notes may be listed, or to conform to usage.

specified therein and shall provide that it shall represent the aggregate amount
of outstanding Notes from time to time endorsed thereon and that the aggregate
amount of outstanding Notes represented 


                                      11

<PAGE>

thereby may from time to time be increased or reduced to reflect transfers or 
exchanges permitted hereby.  Any endorsement of a global Note to reflect the 
amount of any increase or decrease in the amount of outstanding Notes 
represented thereby shall be made by the Trustee or the Custodian, at the 
direction of the Trustee, in such manner and upon instructions given by the 
holder of such Notes in accordance with this Indenture.  Payment of principal 
of and interest and premium, if any, on any global Note shall be made to the 
holder of such Note.

    The terms and provisions contained in the forms of Notes attached as
Exhibits A, B and C hereto shall constitute, and are hereby expressly made, a
part of this Indenture and to the extent applicable, the Company and the
Trustee, by their execution and delivery of this Indenture, expressly agree to
such terms and provisions and to be bound thereby.

    2.3  DATE AND DENOMINATION OF NOTES; PAYMENTS OF INTEREST.  The Notes shall
be issuable in registered form without coupons in denominations of $1,000
principal amount and integral multiples thereof.  Every Note shall be dated the
date of its authentication, shall bear interest from October 14, 1997 and shall
be payable semiannually on each April 15 and October 15, commencing April 15,
1998, except as otherwise specified on the faces of the forms of Notes, attached
as Exhibits A, B and C hereto.

    The person in whose name any Note (or its Predecessor Note) is registered
at the close of business on any record date with respect to any interest payment
date (including any Note that is converted after the record date and on or
before the interest payment date) shall be entitled to receive the interest
payable on such interest payment date notwithstanding the cancellation of such
Note upon any transfer, exchange or conversion subsequent to the record date and
prior to such interest payment date.  Interest may, at the option of the
Company, be paid by check mailed to the address of such person as it appears on
the Note register; PROVIDED that, with respect to any holder of an interest in
any global Note, interest on such holder's Notes shall be paid by wire transfer
in immediately available funds to Cede, the nominee of the Depositary, as
registered owner of the Restricted Global Notes and the Regulation S Global
Note.  The term "record date" with respect to any interest payment date shall
mean the April 1 or October 1 preceding said April 15 or October 15 interest
payment dates, respectively.

    Interest on the Notes shall be computed on the basis of a 360-day year
composed of twelve 30-day months.

    Any interest on any Note that is payable, but is not paid or duly provided
for, on any said April 15 or October 15 (herein called "Defaulted Interest")
shall forthwith cease to be payable to the Holder on the relevant record date by
virtue of his, her or its having been such Holder; and 


                                      12

<PAGE>

such Defaulted Interest shall be paid by the Company, at its election in each 
case, as provided in clause (a) or (b) below:

         (a)  The Company may elect to make payment of any Defaulted Interest
    to the persons in whose names the Notes (or their respective Predecessor
    Notes) are registered at the close of business on a special record date for
    the payment of such Defaulted Interest, which shall be fixed in the
    following manner.  The Company shall notify the Trustee in writing of the
    amount of Defaulted Interest to be paid on each Note and the date of the
    payment (which shall be not less than 25 days after the receipt by the
    Trustee of such notice, unless the Trustee shall consent to an earlier
    date), and at the same time, the Company shall deposit with the Trustee an
    amount of money equal to the aggregate amount to be paid in respect of such
    Defaulted Interest or shall make arrangements satisfactory to the Trustee
    for such deposit prior to the date of the proposed payment, such money when
    deposited to be held in trust for the benefit of the persons entitled to
    such Defaulted Interest as in this clause provided.  Thereupon, the Trustee
    shall fix a special record date for the payment of such Defaulted Interest,
    which shall be not more than 15 days and not less than 10 days prior to the
    date of the payment and not less than 10 days after the receipt by the
    Trustee of the notice of the proposed payment.  The Trustee shall promptly
    notify the Company of such special record date and, in the name and at the
    expense of the Company, shall cause notice of the payment of such Defaulted
    Interest and the special record date therefor to be mailed, first-class
    postage prepaid, to each Holder at his address as it appears in the Note
    register, not less than 10 days prior to such special record date.  Notice
    of the proposed payment of such Defaulted Interest and the special record
    date therefor having been so mailed, such Defaulted Interest shall be paid
    to the persons in whose names the Notes (or their respective Predecessor
    Notes) were registered at the close of business on such special record date
    and shall no longer be payable pursuant to the following clause (b).

         (b)  The Company may make payment of any Defaulted Interest in any
    other lawful manner not inconsistent with the requirements of any
    securities exchange on which the Notes may be listed, and upon such notice
    as may be required by such exchange, if, after notice given by the Company
    to the Trustee of the proposed payment pursuant to this clause, such manner
    of payment shall be deemed practicable by the Trustee.

    2.4  EXECUTION OF NOTES.  The Notes shall be signed in the name and on
behalf of the Company by the signature of its Chief Executive Officer,
President, Chief Operating Officer or Chief Financial Officer and attested by
the signature of its Treasurer, Secretary or any of its Assistant Secretaries
(any of which signatures may be printed, engraved or otherwise reproduced


                                      13

<PAGE>

thereon, by facsimile or otherwise).  Only such Notes as shall bear thereon a
certificate of authentication substantially in the form set forth on forms of
Notes attached as Exhibits A, B and C hereto, manually executed by the Trustee
(or an authenticating agent appointed by the Trustee as provided by Section
16.14), shall be entitled to the benefits of this Indenture or be valid or
obligatory for any purpose.  Such certificate by the Trustee (or such an
authenticating agent) upon any Note executed by the Company shall be conclusive
evidence that the Note so authenticated has been duly authenticated and
delivered hereunder and that the holder is entitled to the benefits of this
Indenture.

    In case any officer of the Company who shall have signed any of the Notes
shall cease to be such officer before the Notes so signed shall have been
authenticated and delivered by the Trustee, or disposed of by the Company, such
Notes nevertheless may be authenticated and delivered or disposed of as though
the person who signed such Notes had not ceased to be such officer of the
Company; and any Note may be signed on behalf of the Company by such persons as,
at the actual date of the execution of such Note, shall be the proper officers
of the Company, although at the date of the execution of this Indenture any such
person was not such an officer.

    2.5  EXCHANGE AND REGISTRATION OF TRANSFER OF NOTES; RESTRICTIONS ON
TRANSFER; DEPOSITARY.

         (a)  The Company shall cause to be kept at the Corporate Trust Office
of the Trustee a register (the register maintained in such office and in any
other office or agency of the Company designated pursuant to Section 4.2 being
herein sometimes collectively referred to as the "Note register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Notes and of transfers of Notes.  Such Note
register shall be in written form or in any form capable of being converted into
written form within a reasonable period of time.  The Trustee is hereby
appointed "Note registrar" for the purpose of registering Notes and transfers of
Notes as herein provided.  The Company may appoint one or more co-registrars.

         Upon surrender for registration of transfer of any Note to the Note
registrar or any co-registrar and satisfaction of the requirements for such
transfer set forth in this Section 2.5, the Company shall execute, and the
Trustee shall authenticate and make available for delivery, in the name of the
designated transferee or transferees, one or more new Notes of any authorized
denominations and of a like aggregate principal amount and bearing such
restrictive legends as may be required by Section 2.5(d).

         Notes may be exchanged for other Notes of any authorized denominations
and of a like aggregate principal amount, upon surrender of the Notes to be
exchanged at any such 


                                      14

<PAGE>

office or agency.  Whenever any Notes are so surrendered for exchange, the 
Company shall execute, and the Trustee shall authenticate and make available 
for delivery, the Notes that the Holder making the exchange is entitled to 
receive.

         All Notes presented or surrendered for registration of transfer or for
exchange shall (if so required by the Company, the Trustee, the Note registrar
or any co-registrar) be duly endorsed, or be accompanied by a written instrument
of transfer in form satisfactory to the Trustee and the Company, executed by the
Holder thereof or his attorney duly authorized in writing.

         No service charge shall be charged to the Holder for any exchange or
registration of transfer of Notes, but the Company may require payment of a sum
sufficient to cover any tax, assessments or other governmental charges that may
be imposed in connection therewith.

         None of the Company, the Trustee, the Note registrar or any 
co-registrar shall be required to exchange or register a transfer of (a) any 
Notes for a period of 15 days next preceding the mailing of a notice of 
redemption, (b) any Notes called for redemption or, if a portion of any Note 
is selected or called for redemption, such portion thereof selected or called 
for redemption, (c) any Notes surrendered for conversion or, if a portion of 
any Note is surrendered for conversion, such portion thereof surrendered for 
conversion or (d) any Notes surrendered for repurchase pursuant to Section 
3.5 or, if a portion of any Note is surrendered for repurchase pursuant to 
Section 3.5, such portion thereof surrendered for repurchase pursuant to 
Section 3.5.

         All Notes issued upon any transfer or exchange of Notes shall be the
valid obligations of the Company, evidencing the same debt and entitled to the
same benefits under this Indenture as the Notes surrendered upon such
registration of transfer or exchange.

         (b)  So long as the Notes are eligible for book-entry settlement with
the Depositary, or unless otherwise required by law, all Notes to be traded on
the PORTAL Market shall be represented by the Restricted Global Notes registered
in the name of the Depositary or the nominee of the Depositary.  The transfer
and exchange of beneficial interests in any global Note that does not involve
the issuance of a definitive Note or the transfer of interests to another global
Note shall be effected through the Depositary (but not the Trustee or the
Custodian) in accordance with this Indenture (including the restrictions on
transfer set forth herein) and the procedures of the Depositary therefor. 
Neither the Trustee nor the Custodian (in such respective capacities) shall have
any responsibility for the transfer and exchange of beneficial interests in such
global Note that does not involve the issuance of a definitive Note or the
transfer of interests to another global Note.


                                      15

<PAGE>

         At any time at the request of the beneficial holder of an interest in
a global Note, such beneficial holder shall be entitled to obtain a definitive
Note upon written request to the Trustee and the Custodian in accordance with
the standing instructions and procedures existing between the Depositary and the
Custodian for the issuance thereof.  Upon receipt of any such request and a
certificate in a form agreed upon by the Company and Trustee (a "Definitive Note
Exchange Certificate"), the Trustee or the Custodian, at the direction of the
Trustee, shall cause, in accordance with the standing instructions and
procedures existing between the Depositary and the Custodian, the aggregate
principal amount of the global Note to be reduced and, following such reduction,
the Company shall execute and the Trustee shall authenticate and make available
for delivery to such beneficial holder (or its nominee) a Note or Notes in the
appropriate aggregate principal amount in the name of such beneficial holder (or
its nominee) and bearing such restrictive legends as may be required by this
Indenture.

         Any transfer of a beneficial interest in a global Note that cannot be
effected through book-entry settlement must be effected by the delivery to the
transferee (or its nominee) of a definitive Note or Notes registered in the name
of the transferee (or its nominee) on the books maintained by the Trustee.  With
respect to any such transfer and upon receipt of a Definitive Note Exchange
Certificate, the Trustee or the Custodian, at the direction of the Trustee,
shall cause, in accordance with the standing instructions and procedures
existing between the Depositary and the Custodian, the aggregate principal
amount of the global Note to be reduced and, following such reduction, the
Company shall execute and the Trustee shall authenticate and make available for
delivery to the transferee (or such transferee's nominee, as the case may be), a

the Trustee shall cancel such definitive Note or Notes and cause, or direct 
the Custodian to cause, in accordance with the standing instructions and 
procedures existing between the Depositary and the Custodian, the aggregate 
principal amount of Notes represented by the Rule 144A Global Note to be

credited a beneficial interest in the Institutional Accredited Investor Global
Note in an amount equal to the beneficial interest in the 144A Global Note to be
exchanged, and (2) an Institutional Accredited Investor Certificate, then the
Trustee, as Registrar, shall instruct the Depositary to reduce or cause to be

maturity of the applicable Institutional Accredited Investor Global Note by the

instructions, a beneficial interest in the Accredited Investor Global Note 
equal to the reduction in the aggregate principal amount at maturity of the 
144A Global Note, and to debit, or cause to be debited, from the account of 
the Person making such exchange or transfer the beneficial interest in the 
144A Global Note that is being exchanged or transferred.

         If a holder of a beneficial interest in the Institutional Accredited
Investor Global Note wishes at any time to exchange its interest in the
Institutional Accredited Investor Global Note for an interest in the Rule 144A
Global Note, or to transfer its interest in the Institutional Accredited
Investor Global Note to a person who wishes to take delivery thereof in the form

instructions a beneficial interest in the applicable 144A Global Note equal to
the reduction in the aggregate principal amount at maturity of such Accredited

Person making such transfer the beneficial interest in the Accredited Investor
Global Note that is being exchanged or transferred.

         If a Holder of a beneficial interest in either of the Restricted 
Global Notes wishes at any time to exchange its interest in such Restricted 
Global Notes for an interest in the Regulation S Global Note, whether before 
or after the expiration of the Restricted Period, or to transfer its interest 
in the Restricted Global Notes to a person who wishes to take delivery

<PAGE>

Regulation S Global Note in an amount equal to the beneficial interest in 
the Restricted Global Notes to be exchanged or transferred, (2) a written 
order given in accordance with the Depositary's procedures containing 
information regarding the Euroclear or Cedel account to be credited with such 
increase and the name of such account, and (3) a Regulation S Certificate, 
the Trustee, as transfer agent, shall promptly deliver appropriate 
instructions to the Depositary (via DWAC), its nominee, or the custodian for 
the Depositary, as the case may be, to reduce or reflect on its records a 
reduction of the relevant Restricted Global Notes by the aggregate principal 
amount of the beneficial interest in such Restricted Global Notes to be so 
exchanged or transferred from the relevant participant, and the Trustee, as 
transfer agent, shall promptly deliver appropriate instructions (via DWAC) to 
the Depositary, its nominee, or the custodian for the Depositary, as the case 
may be, concurrently with such reduction, to increase or reflect on its 
records an increase of the principal amount of such Regulation S Global Note 
by the aggregate principal amount of the beneficial interest in such 
Restricted Global Notes to be so exchanged or transferred, and to credit or 
cause to be credited to the account of the person specified in such 
instructions (who shall be Morgan Guaranty Trust Company of New York, 
Brussels office, as operator of Euroclear or Cedel or another agent member of 
Euroclear or Cedel, or both, as the case may be, acting for and on behalf of 
them) a beneficial interest in such Regulation S Global Note equal to the 
reduction in the principal amount of such Restricted Global Notes.

         If a holder of a beneficial interest in the Regulation S Global Note 
wishes at any time to exchange its interest in the Regulation S Global Note 
for an interest in the Restricted Global Notes, or to transfer its interest 
in the Regulation S Global Note to a person who wishes to take delivery 
thereof in the form of an interest in the Restricted Global Notes, such 
holder may, subject to the rules and procedures of Euroclear or Cedel and the 
Depositary, as the case may be, and to the requirements set forth in the 
following sentence, exchange or cause the exchange or transfer or cause the 
transfer of such interest for an equivalent beneficial interest in such 
Restricted Global Notes.  Upon receipt by the Trustee, as transfer agent, of 
(1) instructions given in accordance with the procedures of Euroclear or 
Cedel and the Depositary, as the case may be, from or on behalf of a 
beneficial owner of an interest in the Regulation S Global Note directing the 
Trustee, as transfer agent, to credit or cause to be credited a beneficial 
interest in the Restricted Global Notes in an amount equal to the beneficial 
interest in the Regulation S Global Note to be exchanged or transferred, (2) 
a written order given in accordance with the procedures of Euroclear or Cedel 
and the Depositary, as the case may be, containing information regarding the 
account with the Depositary to be credited with such increase and the name of 
such account, and (3) on or prior to the expiration of the Restricted Period 
and as applicable, either (i) a Rule 144A Certificate, or (ii) an 
Institutional Accredited Investor Certificate, as applicable, the Trustee, as 
transfer agent, shall promptly deliver (via DWAC) appropriate instructions to 
the Depositary, its nominee, or the custodian for the Depositary, as the case 
may be, to reduce or reflect on its records a reduction of the Regulation S 
Global Note by the aggregate principal 


                                      20

<PAGE>

amount of the beneficial interest in such Regulation S Global Note to be 
exchanged or transferred, and the Trustee, as transfer agent, shall promptly 
deliver (via DWAC) appropriate instructions to the Depositary, its nominee, 
or the custodian for the Depositary, as the case may be, concurrently with 
such reduction, to increase or reflect on its records an increase of the 
principal amount of the Restricted Global Notes by the aggregate principal 
amount of the beneficial interest in the Regulation S Global Note to be so 
exchanged or transferred, and to credit or cause to be credited to the 
account of the person specified in such instructions a beneficial interest in 
the Restricted Global Notes equal to the reduction in the principal amount of 
the Regulation S Global Note.  

         Any beneficial interest in one of the global Notes that is 
transferred to a person who takes delivery in the form of an interest in 
another global Note shall, upon transfer, cease to be an interest in the 
former global Note and become an interest in the latter global Note and, 
accordingly, shall thereafter be subject to all transfer restrictions and 
other procedures applicable to beneficial interests in such latter global 
Note for as long as it remains such an interest.

         Any global Note may be endorsed with or have incorporated in the 
text thereof such legends or recitals or changes not inconsistent with the 
provisions of this Indenture as may be required by the Custodian, the 
Depositary or by the National Association of Securities Dealers, Inc. in 
order for the Notes to be tradeable on the PORTAL Market or as may be 
required for the Notes to be tradeable on any market developed for trading of 
securities pursuant to Rule 144A or required to comply with any applicable 
law or any regulation thereunder or with Regulation S or with the rules and 
regulations of any securities exchange upon which the Notes may be listed or 
traded or to conform with any usage with respect thereto, or to indicate any 
special limitations or restrictions to which any particular Notes are subject.

         (d)  Every Note that bears or is required under this Section 2.5(d) 
to bear the legend set forth in this Section 2.5(d) (together with any Common 
Stock issued upon conversion of the Notes and required to bear the legend set 
forth in Section 2.5(e), collectively, the "Restricted Securities") shall be 
subject to the restrictions on transfer set forth in this Section 2.5(d), 
unless such restrictions on transfer shall have been waived by the written 
consent of the Company or removed in accordance with the provisions of 
Section 2.5(f), and the holder of each such Restricted Security, by such 
holder's acceptance thereof, agrees to be bound by such restrictions on 
transfer.  As used in this Section 2.5(d), the term "transfer" encompasses 
any sale, pledge, transfer or other disposition of any Restricted Security.

         Until two years after the later of the original issuance date of any 
Note and the last date on which the Company or an Affiliate of the Company 
was the owner of such Note, any certificate evidencing such Note (and all 
securities issued in exchange therefor or substitution 

                                       21

thereof, other than Common Stock, if any, issued upon conversion thereof, 
which shall bear the legend set forth in Section 2.5(e), if applicable) shall 
bear a legend in substantially the following form, unless otherwise agreed by 
the Company (with notice thereof to the Trustee):

         THE NOTE EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE U.S.
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
         STATE SECURITIES LAWS, AND MAY NOT BE OFFERED OR SOLD WITHIN THE
         UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS
         EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.  BY ACQUISITION HEREOF,
         THE HOLDER (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL
         BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS
         AN INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1),
         (2), (3) OR (7) UNDER THE SECURITIES ACT) (AN "INSTITUTIONAL
         ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S. PERSON AND IS ACQUIRING
         THE NOTE EVIDENCED HEREBY IN AN OFFSHORE TRANSACTION; (2) AGREES THAT
         IT WILL NOT PRIOR TO THE DATE THAT IS TWO YEARS AFTER THE LATER OF THE
         ORIGINAL ISSUANCE OF THE NOTE EVIDENCED HEREBY AND THE LAST DATE ON
         WHICH CELLSTAR CORPORATION (THE "COMPANY") OR ANY "AFFILIATE" (AS
         DEFINED IN RULE 144 UNDER THE SECURITIES ACT) OF THE COMPANY WAS THE
         OWNER OF THE NOTE (THE "RESTRICTION TERMINATION DATE") RESELL OR
         OTHERWISE TRANSFER THE NOTE EVIDENCED HEREBY OR THE COMMON STOCK
         ISSUABLE UPON CONVERSION OF SUCH NOTE EXCEPT (A) TO THE COMPANY OR ANY
         SUBSIDIARY THEREOF, (B) TO A QUALIFIED INSTITUTIONAL BUYER IN
         COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) TO AN
         INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH TRANSFER,
         FURNISHES TO THE BANK OF NEW YORK, AS TRUSTEE, A SIGNED LETTER
         CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE
         RESTRICTIONS ON TRANSFER OF THE NOTE EVIDENCED HEREBY (THE FORM OF
         WHICH LETTER CAN BE OBTAINED FROM SUCH TRUSTEE), (D) OUTSIDE THE
         UNITED STATES IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT,
         (E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144
         UNDER THE SECURITIES ACT (IF AVAILABLE) OR (F) PURSUANT TO A
         REGISTRATION STATEMENT WHICH HAS BEEN DECLARED 

                                       22
<PAGE>

         EFFECTIVE UNDER THE SECURITIES ACT; AND (3) AGREES THAT IT WILL 
         DELIVER TO EACH PERSON TO WHOM THE NOTE EVIDENCED HEREBY IS 
         TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  
         IN CONNECTION WITH ANY TRANSFER OF THE NOTE EVIDENCED HEREBY BEFORE 
         THE RESTRICTION TERMINATION DATE, THE HOLDER MUST CHECK THE 
         APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER
         OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE BANK OF NEW YORK, 
         AS TRUSTEE.  IF THE PROPOSED TRANSFER IS PURSUANT TO CLAUSE (B), (C), 
         (D) OR (E) ABOVE, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO 
         THE BANK OF NEW YORK, AS TRUSTEE, SUCH CERTIFICATIONS, LEGAL OPINIONS 
         OR OTHER INFORMATION AS THE COMPANY OR TRUSTEE MAY REASONABLY REQUIRE 
         TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION 
         FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION 
         REQUIREMENTS OF THE SECURITIES ACT.  THIS LEGEND WILL BE REMOVED UPON 
         THE RESTRICTION TERMINATION DATE.  AS USED HEREIN, THE TERMS "OFFSHORE
         TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS 
         GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

         Any Note (or security issued in exchange or substitution therefor) 
as to which such restrictions on transfer shall have expired in accordance 
with their terms may, upon satisfaction of the requirements of Section 2.5(f) 
and surrender of such Note for exchange to the Note registrar in accordance 
with the provisions of this Section 2.5, be exchanged for a new Note or 
Notes, of like tenor and aggregate principal amount, which shall not bear the 
restrictive legend required by this Section 2.5(d).

         Notwithstanding any other provisions of this Indenture (other than 
the provisions set forth in this Section 2.5(d)), a global Note may not be 
transferred as a whole except by the Depositary to a nominee of the 
Depositary or by a nominee of the Depositary to the Depositary or another 
nominee of the Depositary or by the Depositary or any such nominee to a 
successor Depositary or a nominee of such successor Depositary.

         The Depositary shall be a clearing agency registered under the 
Exchange Act.  The Company initially appoints The Depository Trust Company to 
act as Depositary with respect to the global Notes.  Initially, the global 
Notes shall be issued to the Depositary, 

                                       23
<PAGE>

registered in the name of Cede & Co., as the nominee of the Depositary, and 
deposited with the Trustee as Custodian for Cede & Co.

         If at any time the Depositary for the global Notes notifies the 
Company that it is unwilling or unable to continue as Depositary for such 
Notes, the Company may appoint a successor Depositary with respect to such 
Notes.  If a successor Depositary for the Notes is not appointed by the 
Company within 90 days after the Company receives such notice, the Company 
shall execute, and the Trustee, upon receipt of an Officers' Certificate for 
the authentication and delivery of Notes, shall authenticate and make 
available for delivery, Notes in definitive form, in an aggregate principal 
amount equal to the principal amount of the global Notes in exchange for such 
global Notes.

         Definitive Notes issued in exchange for all or a part of a global 
Note pursuant to this Section 2.5(d) shall be registered in such names and in 
such authorized denominations as the Depositary, pursuant to instructions 
from its direct or indirect participants or otherwise, shall instruct the 
Trustee.  Upon execution and authentication, the Trustee shall make available 
for delivery such definitive Notes to the persons in whose names such 
definitive Notes are so registered.

         At such time as all interests in global Notes have been redeemed, 
converted, repurchased or canceled, such global Notes shall be, upon receipt 
thereof, canceled by the Trustee in accordance with standing procedures and 
instructions existing between the Depositary and the Custodian.  At any time 
prior to such cancellation, if any interest in a global Note is exchanged for 
definitive Notes, redeemed, converted, canceled or transferred to a 
transferee who receives definitive Notes therefor or any definitive Note is 
exchanged or transferred for part of a global Note, the principal amount of 
such global Note shall, in accordance with the standing procedures and 
instructions existing between the Depositary and the Custodian, be reduced or 
increased, as the case may be, and an endorsement shall be made on such 
global Note by the Trustee or the Custodian, at the direction of the Trustee, 
to reflect such reduction or increase.

         The Company and the Trustee may for all purposes, including the 
making of payments due on the Notes, deal with the Depositary as the 
authorized representative of the Holders for the purposes of exercising the 
rights of Holders hereunder.  The rights of the owner of any beneficial 
interest in a global Note shall be limited to those established by law and 
agreements between such owners and depository participants or Euroclear and 
Cedel; provided that no such agreement shall give any rights to any person 
against the Company or the Trustee without the written consent of the parties 
so affected.  Multiple requests and directions from and votes of, the 
Depositary as holder of notes in book entry form with respect to any 
particular 

                                      24
<PAGE>

matter shall not be deemed inconsistent to the extent they do not represent 
an amount of notes in excess of those held in the name of the Depositary or 
its nominee.

         (e)  Until two years after the later of the original issuance date 
of any Note (other than any Note represented by the Regulation S Global Note) 
and the last date on which the Company or an Affiliate of the Company was the 
owner of such Note, any stock certificate representing Common Stock issued 
upon conversion of such Note shall bear a legend in substantially the 
following form, unless otherwise agreed by the Company (with written notice 
thereof to the Trustee and any transfer agent for the Common Stock):

         THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN REGISTERED UNDER THE

         UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S. PERSONS
         EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.  THE HOLDER HEREOF

         DATE"), (1) IT WILL NOT RESELL OR OTHERWISE TRANSFER THE COMMON STOCK
         EVIDENCED HEREBY EXCEPT (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF,

         TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT; AND (3) IT
         WILL DELIVER TO EACH PERSON TO WHOM THE COMMON STOCK EVIDENCED HEREBY
         IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. 
         THIS LEGEND WILL BE REMOVED UPON THE RESTRICTION TERMINATION DATE.  AS
         USED HEREIN, THE TERMS "UNITED STATES" AND "U.S. PERSON" HAVE THE
         MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

         Any such Common Stock as to which such restrictions on transfer 
shall have expired in accordance with their terms may, upon satisfaction of 
the requirements of Section 2.5(f) and surrender of the certificates 
representing such shares of Common Stock for exchange in accordance with the 
procedures of the transfer agent for the Common Stock, be exchanged for a new 
certificate or certificates for a like aggregate number of shares of Common 
Stock, which shall not bear the restrictive legend required by this Section 
2.5(e).

         (f)  Upon any sale or transfer of any Restricted Security (including 
any interest in a global Note) (i) that is effected pursuant to an effective 
registration statement under the Securities Act, (ii) that is effected 
pursuant to Rule 144 as promulgated under the Securities Act as determined by 
counsel to the Company or the Trustee or (iii) in connection with which the 
Trustee (or transfer agent for the Common Stock, in the case of shares of 
Common Stock) receives certificates and other information (including an 
opinion of counsel, if requested) reasonably acceptable to the Company and 
the Trustee (or such transfer agent, as the case may be) to the effect that 
such security shall no longer be subject to the resale restrictions under 
federal and state securities laws, then (A) in the case of a Restricted 
Security in definitive form, the Note registrar or co-registrar (or transfer 
agent, in the case of Common Stock) shall permit the holder thereof to 
exchange such Restricted Security for a security that does not bear the 
legends set forth in Section 2.5(d) or 2.5(e), as applicable, and shall 
rescind any such restrictions 

                                      26
<PAGE>

on transfer and (B) in the case of Restricted Securities represented by a 
global Note, such Note shall no longer be subject to the restrictions 
contained in the legend set forth in Section 2.5(d) (but still subject to the 
other provisions hereof).  In addition, any Note (or security issued in 
exchange or substitution therefor) or shares of Common Stock issued upon 
conversion of any Note, in either case, as to which the restrictions on 
transfer described in the legends set forth in Section 2.5(d) and 2.5(e), 
respectively, have expired by their terms, may, upon surrender thereof (in 
accordance with the terms of this Indenture in the case of Notes) together 
with such certifications and other information (including an opinion of 
counsel having substantial experience in practice under the Securities Act 
and otherwise reasonably acceptable to the Company, addressed to the Company 
and the Trustee and in a form acceptable to the Company, to the effect that 
the transfer of such Restricted Security has been made in compliance with 
Rule 144 or such successor provision) acceptable to the Company and the 
Trustee (or transfer agent, as the case may be) as either of them may 
reasonably require, be exchanged for a new Note or Notes of like tenor and 
aggregate principal amount (in the case of Notes), or a new certificate or 
certificates for a like aggregate number of shares of Common Stock (in the 
case of Common Stock), or a new certificate or other instrument of like tenor 
and amount (in the case of securities issued in exchange or substitution for 
Notes), which shall not bear the restrictive legends set forth in Sections 
2.5(d) and 2.5(e).

         (g)  Each holder of a Note agrees to indemnify the Company and the 
Trustee against any liability that may result from the transfer, exchange or 
assignment of such holder's Note in violation of any provision of this 
Indenture and/or applicable U.S. federal or state securities law.

         The Trustee shall have no obligation or duty to monitor, determine 
or inquire as to compliance with any restrictions on transfer imposed under 
this Indenture or under applicable law with respect to any transfer of any 
interest in any Note (including any transfers between or among Depositary 
Participants or beneficial owners of interests in any Global Note) other than 
to require delivery of such certificates and other documentation or evidence 
as are expressly required by, and to do so if and when expressly required by 
the terms of, this Indenture, and to examine the same to determine 
substantial compliance as to form with the express requirements hereof.

    2.6  MUTILATED, DESTROYED, LOST OR STOLEN NOTES.  In case any Note shall 
become mutilated or be destroyed, lost or stolen, the Company in its 
discretion may execute, and upon its request, the Trustee or an 
authenticating agent appointed by the Trustee shall authenticate and make 
available for delivery a new Note bearing a number not contemporaneously 
outstanding in exchange and substitution for the mutilated Note or in lieu of 
and in substitution for the Note so destroyed, lost or stolen.  The Company 
may charge such applicant for the expenses of the 

                                      27
<PAGE>

Company in replacing a Note.  In every case the applicant for a substituted 
Note shall furnish to the Company, to the Trustee and, if applicable, to such 
authenticating agent such security or indemnity as may be required by them to 
save each of them harmless from any loss, liability, cost or expense caused 
by or connected with such substitution, and in every case of destruction, 
loss or theft, the applicant shall also furnish to the Company, to the 
Trustee and, if applicable, to such authenticating agent evidence to their 
satisfaction of the destruction, loss or theft of such Note and of the 
ownership thereof.

    The Trustee or such authenticating agent may authenticate any such 
substituted Note and deliver the same upon the receipt of such security or 
indemnity as the Trustee, the Company and, if applicable, such authenticating 
agent may require.  Upon the issuance of any substituted Note, the Company 
may require the payment of a sum sufficient to cover any tax or other 
governmental charge that may be imposed in relation thereto and any other 
expenses connected therewith.  In case any Note that has matured or is about 
to mature or has been called for redemption or is about to be converted into 
Common Stock shall become mutilated or be destroyed, lost or stolen, the 
Company may, instead of issuing a substitute Note, pay or authorize the 
payment of or convert or authorize the conversion of the same (without 
surrender thereof, except in the case of a mutilated Note), as the case may 
be, if the applicant for such payment or conversion shall furnish to the 
Company, to the Trustee and, if applicable, to such authenticating agent such 
security or indemnity as may be required by them to save each of them 
harmless from any loss, liability, cost or expense caused by or connected 
with such substitution, and in case of destruction, loss or theft, evidence 
satisfactory to the Company, the Trustee and, if applicable, any paying agent 
or conversion agent of the destruction, loss or theft of such Note and of the 
ownership thereof.

    Every substitute Note issued pursuant to the provisions of this Section 
2.6 in lieu of any Note that is destroyed, lost or stolen shall constitute an 
additional contractual obligation of the Company, whether or not the 
destroyed, lost or stolen Note shall be enforceable by anyone, and shall be 
entitled to all the benefits of (but shall be subject to all the limitations 
set forth in) this Indenture equally and proportionately with any and all 
other Notes duly issued hereunder.  To the extent permitted by law, all Notes 
shall be held and owned upon the express condition that the foregoing 
provisions are exclusive with respect to the replacement or payment or 
conversion of mutilated, destroyed, lost or stolen Notes and shall preclude 
any and all other rights or remedies notwithstanding any law or statute 
existing or hereafter enacted to the contrary with respect to the replacement 
or payment or conversion of negotiable instruments or other securities 
without their surrender.

    2.7  TEMPORARY NOTES.  Pending the preparation of definitive Notes, the 
Company may execute and the Trustee or an authenticating agent appointed by 
the Trustee shall, upon 

                                      28
<PAGE>

written request of the Company, authenticate and make available for delivery 
temporary Notes (printed or lithographed).  Temporary Notes shall be issuable 
in any authorized denomination and shall be substantially in the form of the 
definitive Notes but with such omissions, insertions and variations as may be 
appropriate for temporary Notes, all as may be determined by the Company.  
Every such temporary Note shall be executed by the Company and authenticated 
by the Trustee or such authenticating agent upon the same conditions and in 
substantially the same manner, and with the same effect, as the definitive 
Notes.  Without unreasonable delay the Company shall execute and deliver to 
the Trustee or such authenticating agent definitive Notes (other than in the 
case of Notes in global form) and thereupon any or all temporary Notes (other 
than any such global Note) may be surrendered in exchange therefor, at each 
office or agency maintained by the Company pursuant to Section 4.2 and the 
Trustee or such authenticating agent shall authenticate and make available 
for delivery in exchange for such temporary Notes an equal aggregate 
principal amount of definitive Notes.  Such exchange shall be made by the 
Company at its own expense and without any charge therefor.  Until so 
exchanged, the temporary Notes shall in all respects be entitled to the same 
benefits and subject to the same limitations under this Indenture as 
definitive Notes authenticated and delivered hereunder.

    2.8  CANCELLATION OF NOTES PAID, ETC.  All Notes surrendered for the 
purpose of payment, redemption, conversion, exchange or registration of 
transfer shall, if surrendered to the Company or any paying agent or any Note 
registrar or any conversion agent, be surrendered to the Trustee and promptly 
canceled by it or, if surrendered to the Trustee, shall be promptly canceled 
by it and no Notes shall be issued in lieu thereof except as expressly 
permitted by any of the provisions of this Indenture.  If required by the 
Company, the Trustee shall return canceled Notes to the Company.  If the 
Company shall acquire any of the Notes, such acquisition shall not operate as 
a redemption or satisfaction of the indebtedness represented by such Notes 
unless and until the same are delivered to the Trustee for cancellation.

    2.9  CUSIP NUMBERS.  The Company in issuing the Notes may use "CUSIP" 
numbers (if then generally in use), and, if so, the Trustee shall use CUSIP 
numbers in notices of redemption as a convenience to holders; provided that 
any such notice may state that no representation is made as to the 
correctness of such numbers either as printed on the Notes or as contained in 
any notice of a redemption and that reliance may be placed only on the other 
identification numbers printed on the Notes, and any such redemption shall 
not be affected by any defect in or omission of such numbers.  The Company 
shall promptly notify the Trustee of any change in the CUSIP numbers.
                                       
                                      III

                                      29
<PAGE>

    3.1   REDEMPTION PRICES.  The Notes are not redeemable at the option of 
the Company prior to October 18, 2000.  At any time on or after that date, 
the Notes may be redeemed at the Company's option, upon notice as set forth 
in Section 3.2, in whole at any time or in part from time to time, at the 
optional redemption prices set forth below plus accrued and unpaid interest 
thereon to the applicable redemption date if redeemed after: 

                                                          Redemption 
Date                                                         Price
- ----                                                         -----
October 18, 2000                                              102%
October 15, 2001                                              101%

    3.2  NOTICE OF REDEMPTION; SELECTION OF NOTES.  In case the Company shall 
desire to exercise the right to redeem all or, as the case may be, any part 
of the Notes pursuant to Section 3.1, it shall fix a date for redemption and, 
in the case of any redemption pursuant to Section 3.1, it or, at its request 
accompanied by the proposed form of notice of redemption (which must be 
received by the Trustee at least ten days prior to the date the Trustee is 
requested to give notice as described below, unless a shorter period is 
agreed to by the Trustee), the Trustee in the name of and at the expense of 
the Company, shall publish a notice in THE WALL STREET JOURNAL and mail or 
cause to be mailed a notice of such redemption at least 30 and not more than 
60 days prior to the date fixed for redemption to the holders of Notes so to 
be redeemed as a whole or in part at their last addresses as the same appear 
on the Note register, provided that if the Company shall give such notice, it 
shall also give such notice, and notice of the Notes to be redeemed, to the 
Trustee.  Such mailing shall be by first class mail.  The notice, if mailed 
in the manner herein provided, shall be conclusively presumed to have been 
duly given, whether or not the holder receives such notice.  In any case, 
failure to give such notice by mail or any defect in the notice to the holder 
of any Note designated for redemption as a whole or in part shall not affect 
the validity of the proceedings for the redemption of any other Note.

    Each such notice of redemption shall identify the Notes to be redeemed 
(including CUSIP numbers), specify the aggregate principal amount of Notes to 
be redeemed, the date fixed for redemption, the redemption price at which 
Notes are to be redeemed, the place or places of payment, that payment shall 
be made upon presentation and surrender of such Notes, that interest accrued 
to the date fixed for redemption shall be paid as specified in said notice 
and that on and after said date, interest thereon or on the portion thereof 
to be redeemed shall cease to accrue.  Such notice shall also state the 
current Conversion Price and the date on which the right to convert such 
Notes or portions thereof into Common Stock shall expire.  If fewer than all 
the Notes are to be redeemed, the notice of redemption shall identify the 
Notes to be redeemed.  In case any Note is to be redeemed in part only, the 
notice of redemption shall state the portion of the principal amount thereof 
to be redeemed and shall state that on and after the date fixed for 

                                      30
<PAGE>

redemption, upon surrender of such Note, a new Note or Notes in principal 
amount equal to the unredeemed portion thereof shall be issued.

    On or prior to the Business Day prior to the redemption date specified in 
the notice of redemption given as provided in this Section 3.2, the Company 
shall deposit with the Trustee or with one or more paying agents (or, if the 
Company is acting as its own paying agent, set aside, segregate and hold in 
trust as provided in Section 4.4) an amount of money sufficient to redeem on 
the redemption date all the Notes so called for redemption (other than those 
theretofore surrendered for conversion into Common Stock) at the appropriate 
redemption price, together with accrued interest to the date fixed for 
redemption.  If any Note called for redemption is converted pursuant hereto, 
any money deposited with the Trustee or any paying agent or so segregated and 
held in trust for the redemption of such Note shall be paid to the Company 
upon its request or, if then held by the Company, shall be discharged from 
such trust. If fewer than all the Notes are to be redeemed, the Company shall 
give the Trustee written notice in the form of an Officers' Certificate not 
fewer than 45 days (or such shorter period of time as may be acceptable to 
the Trustee) prior to the redemption date as to the aggregate principal 
amount of Notes to be redeemed.

    If fewer than all the Notes are to be redeemed, the Trustee shall select 
the Notes or portions thereof to be redeemed (in principal amounts of $1,000 
or integral multiples thereof), by lot or, in its discretion, on a PRO RATA 
basis. If any Note selected for partial redemption is converted in part after 
such selection, the converted portion of such Note shall be deemed (so far as 
may be) to be the portion to be selected for redemption.  The Notes (or 
portions thereof) so selected shall be deemed duly selected for redemption 
for all purposes hereof, notwithstanding that any such Note is converted as a 
whole or in part before the mailing of the notice of redemption.

    Upon any redemption of less than all Notes, the Company and the Trustee 
may treat as outstanding any Notes surrendered for conversion during the 
period of 15 days next preceding the mailing of a notice of redemption and 
need not treat as outstanding any Note authenticated and delivered during 
such period in exchange for the unconverted portion of any Note converted in 
part during such period.

    3.3  PAYMENT OF NOTES CALLED FOR REDEMPTION.  If notice of redemption has 
been given as above provided, the Notes or portion of Notes with respect to 
which such notice has been given shall, unless converted into Common Stock 
pursuant to the terms hereof, become due and payable on the date and at the 
place or places stated in such notice at the applicable redemption price, 
together with interest thereon accrued to the date fixed for redemption, and 
on and after said date (unless the Company shall default in the payment of 
such Notes at the 

                                      31
<PAGE>

redemption price, together with interest thereon accrued to said date), 
interest on the Notes or portion of Notes so called for redemption shall 
cease to accrue, and such Notes shall cease after the close of business on 
the Business Day next preceding the date fixed for redemption to be 
convertible into Common Stock and, except as provided in Sections 7.6 and 
12.5, to be entitled to any benefit or security under this Indenture, and the 
holders thereof shall have no right in respect of such Notes except the right 
to receive the redemption price thereof and unpaid interest thereon to the 
date fixed for redemption.  On presentation and surrender of such Notes at a 
place of payment in said notice specified, the said Notes or the specified 
portions thereof shall be paid and redeemed by the Company at the applicable 
redemption price, together with interest accrued thereon to the date fixed 
for redemption; provided that any semi-annual payment of interest becoming 
due on the date fixed for redemption shall be payable to the holders of such 
Notes registered as such on the relevant record date subject to the terms and 
provisions of Section 2.3 hereof.

    Upon presentation of any Note redeemed in part only, the Company shall 
execute and the Trustee shall authenticate and make available for delivery to 
the holder thereof, at the expense of the Company, a new Note or Notes, of 
authorized denominations, in principal amount equal to the unredeemed portion 
of the Notes so presented.

    If any Note called for redemption shall not be so paid upon surrender 
thereof for redemption, the principal and premium, if any, shall, until paid 
or duly provided for, bear interest from the date fixed for redemption at the 
rate borne by the Note and such Note shall remain convertible into Common 
Stock until the principal and premium, if any, shall have been paid or duly 
provided for.

    3.4  CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION.  In connection with 
any redemption of Notes, the Company may arrange for the purchase and 
conversion of any Notes by an agreement with one or more investment bankers 
or other purchasers to purchase such Notes by such investment bankers or 
other purchasers paying to the Trustee in trust for the Holders, on or prior 
to the last Business Day prior to the date fixed for redemption, an amount 
not less than the applicable redemption price, together with interest accrued 
to the date fixed for redemption, of such Notes.  Notwithstanding anything to 
the contrary contained in this Article III, the obligation of the Company to 
pay the redemption price of such Notes, together with interest accrued to the 
date fixed for redemption, shall be deemed to be satisfied and discharged to 
the extent such amount is so paid by such purchasers.  If such an agreement 
is entered into, a copy of which shall be filed with the Trustee prior to the 
date fixed for redemption, any Notes not duly surrendered for conversion by 
the holders thereof may, at the option of the Company, be deemed, to the 
fullest extent permitted by law, acquired by such purchasers from such 
holders and (notwithstanding anything to the contrary contained in Article 
XIV) surrendered by such 

                                      32
<PAGE>

purchasers for conversion, all as of the time immediately prior to the close 
of business on the date fixed for redemption (and the right to convert any 
such Notes shall be deemed to have been extended through such time), subject 
to payment of the above amount as aforesaid.  At the direction of the 
Company, the Trustee shall hold and dispose of any such amount paid to it in 
the same manner as it would monies deposited with it by the Company for the 
redemption of Notes. Without the Trustee's prior written consent, no 
arrangement between the Company and such purchasers for the purchase and 
conversion of any Notes shall increase or otherwise affect any of the powers, 
duties, responsibilities or obligations of the Trustee as set forth in this 
Indenture, and the Company agrees to indemnify the Trustee from, and hold it 
harmless against, any loss, liability or expense arising out of or in 
connection with any such arrangement for the purchase and conversion of any 
Notes between the Company and such purchasers including the costs and 
expenses incurred by the Trustee in the defense of any claim or liability 
arising out of or in connection with the exercise or performance of any of 
its powers, duties, responsibilities or obligations under this Indenture.

    3.5  PURCHASE OF NOTES UPON A CHANGE OF CONTROL.

         (a)  If a Change of Control shall occur at any time, then each 
holder of Notes shall have the right to require that the Company repurchase 
such holder's Notes in whole or in part in integral multiples of $1,000 at a 
purchase price (the "Change of Control Purchase Price") in cash in an amount 
equal to 101% of the principal amount of such Notes, plus accrued and unpaid 
interest thereon, if any, to the purchase date (the "Change of Control 
Purchase Date") pursuant to the offer described below (the "Change of Control 
Offer") and in accordance with the other procedures set forth in this 
Indenture.

         (b)  Within 30 days following any Change of Control, unless the 
Company has given the Holders notice of its intention to redeem the Notes 
pursuant to Section 3.1, the Company shall notify the Trustee and give 
written notice of such Change of Control to each Holder of Notes, by 
first-class mail, postage prepaid, at the Holder's address appearing in the 
Note register, stating, among other things, (i) that a Change of Control has 
occurred, (ii) the Change of Control Purchase Price, (iii) the Change of 
Control Purchase Date (which shall be a Business Day no earlier than 30 days 
nor later than 60 days from the date such notice is mailed, or such later 
date as is necessary to comply with requirements under the Exchange Act), 
(iv) that any Note not tendered shall continue to accrue interest and to have 
all of the benefits of this Indenture, (v) that, unless the Company defaults 
in the payment of the Change of Control Purchase Price, any Notes accepted 
for payment pursuant to the Change of Control Offer shall cease to accrue 
interest after the Change of Control Purchase Date, (vi) that Holders 
electing to have any Notes purchased pursuant to a Change of Control Offer 
shall be required to surrender the Notes, with the form entitled "Option of 
Holder to Elect Purchase" on the reverse of the 

                                      33
<PAGE>

Notes completed, to the Company at the address specified in the notice prior 
to the close of business on the third Business Day preceding the Change of 
Control Purchase Date, (vii) that Holders shall be entitled to withdraw their 
election if the Company receives, not later than the close of business on the 
second Business Day preceding the Change of Control Purchase Date, a 
telegram, telex, facsimile transmission or letter setting forth the name of 
the Holder, the principal amount of Notes delivered for purchase, and a 
statement that such Holder is withdrawing his election to have such Notes 
purchased, and (viii) that Holders whose Notes are being purchased only in 
part shall be issued new Notes equal in principal amount to the unpurchased 
portion of the Notes surrendered, which unpurchased portion must be equal to 
$1,000 in principal amount or an integral multiple thereof.  Prior to being 
required to purchase any Notes pursuant to this Section 3.5 and prior to the 
mailing of the notice of the Change of Control to the Holders, but in any 
event within 30 days following any Change of Control, the Company shall 
either (i) repay in full all of the Designated Senior Indebtedness and 
terminate all commitments thereunder or offer to do so and repay the 
Designated Senior Indebtedness and terminate all commitments of each lender 
thereunder who accepted such offer or (ii) obtain the requisite consent under 
the Designated Senior Indebtedness to permit the repurchase of the Notes 
pursuant to this Section 3.5.  The Company shall comply with the requirements 
of Rule 13e-4 and 14e-1 under the Exchange Act and any other securities laws 
and regulations thereunder to the extent such laws and regulations are 
applicable in connection with the repurchase of the Notes in connection with 
a Change of Control.

         (c)  On the Change of Control Purchase Date, the Company shall, to 
the extent lawful, (i) accept for payment Notes or portions thereof tendered 
pursuant to the Change of Control Offer, (ii) deposit with the Trustee an 
amount equal to the Change of Control Purchase Price in respect of all Notes 
or portions thereof so tendered and (iii) deliver or cause to be delivered to 
the Trustee the Notes so accepted together with an Officers' Certificate 
stating the Notes or portions thereof tendered to the Company.  The Trustee 
shall promptly mail to each Holder of Notes so accepted payment in an amount 
equal to the purchase price of such Notes, and the Trustee shall promptly 
authenticate and mail to each Holder a new Note equal in principal amount to 
any unpurchased portion of the Notes surrendered, if any; provided that each 
such new Note shall be in a principal amount of $1,000 or an integral 
multiple thereof.  The Company shall publicly announce the results of the 
Change of Control Offer on or as soon as practicable after the Change of 
Control Payment Date.

         (d)  The term "Change in Control" shall mean an event or series of 
events as a result of which (i) any "person" or "group" (as such terms are 
used in Sections 13(d) and 14(d) of the Exchange Act), other than an Excluded 
Person (as defined below), acquires "beneficial ownership" (as determined in 
accordance with Rule 13d-3 under the Exchange Act), directly or indirectly, 
of more than fifty percent (50%) of the combined voting power of the then 

                                      34
<PAGE>

outstanding securities entitled to vote generally in elections of directors 
of the Company (the "Voting Stock") or (ii) the Company consolidates or 
merges with any other corporation or business entity, or conveys, transfers 
or leases all or substantially all of its assets to any person, unless the 
shareholders of the Company immediately before such transaction own, directly 
or indirectly, at least fifty-one percent (51%) of the combined voting power 
of the outstanding voting securities of the corporation resulting from such 
transaction in substantially the same proportion as their ownership of the 
Voting Stock immediately before such transaction; PROVIDED, that a Change of 
Control shall not be deemed to have occurred if either (i) the closing price 
per share of the Common Stock for any 5 trading days within the period of 10 
consecutive trading days ending immediately after the announcement of the 
Change in Control transaction shall equal or exceed 105% of the conversion 
price of the Notes in effect on the trading day on which such announcement is 
made or (ii) at least 90% of the consideration (determined on the date on 
which the Change of Control is triggered and excluding cash payments for 
fractional shares) in the Change of Control transaction consists of shares of 
common stock traded on a national securities exchange or quoted on the Nasdaq 
Stock Market and as a result of such transaction or transactions, the Notes 
become convertible solely into such common stock; PROVIDED, FURTHER, that no 
Change of Control shall be deemed to have occurred from a transfer of the 
Company's voting securities by Mr. Alan H. Goldfield ("Goldfield") to (v) a 
member of Goldfield's immediate family (determined in accordance with Rule 
16a-1(e) of the Exchange Act) either during Goldfield's lifetime or by will 
or the laws of descent and distribution; (w) any trust as to which Goldfield 
or a member of (or members) of his immediate family is the beneficiary; (x) 
any trust as to which Goldfield is the settlor with sole power to revoke; (y) 
any entity over which Goldfield has the power, directly or indirectly, to 
direct or cause the direction of the management and policies of the entity, 
whether through the ownership of voting securities, by contract or otherwise; 
or (z) any charitable trust, foundation or corporation under Section

                     PARTICULAR COVENANTS OF THE COMPANY

    4.1  PAYMENT OF PRINCIPAL, PREMIUM AND INTEREST.  The Company covenants 
and agrees that it shall duly and punctually pay or cause to be paid the 
principal of and premium, if any, and interest on each of the Notes at the 
places, at the respective times and in the manner provided herein and in the 
Notes.  Each installment of interest on the Notes due on any semi-annual 
interest payment date may be paid by (i) wire transfer in immediately 
available funds to the Depositary or its nominee, as registered owner of the 
Global Notes, or (ii) mailing checks for the interest payable to or upon the 
written order of the holders of definitive Notes entitled thereto as they 
shall appear on the Note register.  An installment of principal or interest 
shall be considered paid on the date due if the Trustee or paying agent 
(other than the Company, a subsidiary of the Company or any Affiliate of any 
of them) holds on that date money designated for and sufficient to pay the 
installment of principal or interest and is not prohibited from paying such 
money to the holders of the Notes pursuant to the terms of this Indenture.

    4.2  MAINTENANCE OF OFFICE OR AGENCY.  The Company shall maintain in the 
Borough of Manhattan, The City of New York, an office or agency where the 
Notes may be surrendered for registration of transfer or exchange or for 
presentation for payment or for conversion or redemption and where notices 
and demands to or upon the Company in respect of the Notes and this Indenture 
may be served.  The Company shall give prompt written notice to the Trustee 
of the location, and any change in the location, of such office or agency.  
If at any time the Company shall fail to maintain any such office or agency 
or shall fail to furnish the Trustee with the address thereof, such 
presentations, surrenders, notices and demands may be made or served at the 
Corporate Trust Office of the Trustee.

    The Company may also from time to time designate one or more other 
offices or agencies where the Notes may be presented or surrendered for any 
or all such purposes and may from time to time rescind such designations; 
provided that no such designation or rescission shall in any manner relieve 
the Company of its obligation to maintain an office or agency in the Borough 
of Manhattan, The City of New York, for such purposes.  The Company shall 
give prompt written notice to the Trustee of any such designation or 
rescission and of any change in the location of any such other office or 
agency.

    The Company hereby initially designates the Trustee as paying agent, Note 
registrar and conversion agent and each of the Corporate Trust Office of the 
Trustee and the office of The Bank of New York in the Borough of Manhattan, 
The City of New York, as one such office or agency of the Company for the 
purposes set forth in the first paragraph of this Section 4.2.

                                      36
<PAGE>

    So long as the Trustee is the Note registrar, the Trustee agrees to mail, 
or cause to be mailed, the notices set forth in Section 7.11(a) and the third 
paragraph of Section 7.12.

    4.3  APPOINTMENTS TO FILL VACANCIES IN TRUSTEE'S OFFICE.  The Company, 
whenever necessary to avoid or fill a vacancy in the office of Trustee, shall 
appoint, in the manner provided in Section 7.11, a Trustee, so that there 
shall at all times be a Trustee hereunder.

    4.4  PROVISIONS AS TO PAYING AGENT.

         (a)  If the Company shall appoint a paying agent other than the 
Trustee, or if the Trustee shall appoint such a paying agent, the Company or 
the Trustee, as the case may be, shall cause such paying agent to execute and 
deliver to the Trustee an instrument in which such agent shall agree with the 
Trustee, subject to the provisions of this Section 4.4:

              (1)  that it shall hold all sums held by it as such agent for the
    payment of the principal of, premium, if any, or interest on the Notes
    (whether such sums have been paid to it by the Company or by any other
    obligor on the Notes) in trust for the benefit of the holders of the Notes;

              (2)  that it shall give the Trustee notice of any failure by the
    Company (or by any other obligor on the Notes) to make any payment of the
    principal of, premium, if any, or interest on the Notes when the same shall
    be due and payable; and

              (3)  that at any time during the continuance of an Event of
    Default, upon request of the Trustee, it shall forthwith pay to the Trustee
    all sums so held in trust.

    The Company shall, before each due date of the principal of, premium, if 
any, or interest on the Notes, deposit with the paying agent a sum sufficient 
to pay such principal, premium, if any, or interest, and (unless such paying 
agent is the Trustee) the Company shall promptly notify the Trustee of any 
failure to take such action.

         (b)  If the Company shall act as its own paying agent, it shall, on 
or before each due date of the principal of, premium, if any, or interest on 
the Notes, set aside, segregate and hold in trust for the benefit of the 
holders of the Notes a sum sufficient to pay such principal, premium, if any, 
or interest so becoming due and shall notify the Trustee of any failure to 
take such action and of any failure by the Company (or any other obligor 
under the Notes) to make any payment of the principal of, premium, if any, or 
interest on the Notes when the same shall become due and payable.

                                      37
<PAGE>

         (c)  Anything in this Section 4.4 to the contrary notwithstanding, 
the Company may, at any time, for the purpose of obtaining a satisfaction and 
discharge of this Indenture, or for any other reason, pay or cause to be paid 
to the Trustee all sums held in trust by the Company or any paying agent 
hereunder as required by this Section 4.4, such sums to be held by the 
Trustee upon the trusts herein contained and upon such payment by the Company 
or any paying agent to the Trustee, the Company or such paying agent shall be 
released from all further liability with respect to such sums.

         (d)  Anything in this Section 4.4 to the contrary notwithstanding, 
the agreement to hold sums in trust as provided in this Section 4.4 is 
subject to Sections 12.3 and 12.4.

    4.5  CORPORATE EXISTENCE.  Subject to Article XI, the Company shall do or 
cause to be done all things necessary to preserve and keep in full force and 
effect (i) its corporate existence, and the corporate, partnership or other 
existence of any subsidiary of the Company, in accordance with the respective 
organizational documents (as the same may be amended from time to time) of 
the Company or any such subsidiary and (ii) the material rights (charter and 
statutory), licenses and franchises of the Company and its subsidiaries; 
provided that the Company shall not be required to preserve any such right, 
license or franchise, or the corporate, partnership or other existence of any 
of its subsidiaries if the Company shall determine in good faith that the 
preservation thereof is no longer desirable in the conduct of the business of 
the Company and its subsidiaries, taken as a whole, and that the loss thereof 
is not materially adverse to the Holders of the Notes.

    4.6  RULE 144A INFORMATION REQUIREMENT.  During the two-year period 
following the original issuance date of any Note and during the two-year 
period following the last date on which the Company or an Affiliate of the 
Company was the owner of any Note (or shares of Common Stock issued upon 
conversion of any Note), if the Company is subject neither to Section 13 nor 
Section 15(d) of the Exchange Act, the Company shall at the written request 
of any holder or beneficial holder of such Note (or shares of Common Stock 
issued upon conversion of Notes) provide to such holder or beneficial holder 
of such Note (or shares of Common Stock issued upon conversion of Notes) and 
any prospective transferee designated by such holder or beneficial holder of 
such Note (or shares of Common Stock issued upon conversion of Notes) such 
information, if any, required by Rule 144A(d)(4) under the Securities Act (so 
long as such information is required to permit such transfer under Rule 144A).

    4.7  STAY, EXTENSION AND USURY LAWS.  The Company covenants (to the 
extent that it may lawfully do so) that it shall not at any time insist upon, 
plead or in any manner whatsoever claim or take the benefit or advantage of, 
any stay, extension or usury law or other law that 

                                      38
<PAGE>

would prohibit or forgive the Company from paying all or any portion of the 
principal of, premium, if any, or interest on the Notes as contemplated 
herein, wherever enacted, now or at any time hereafter in force, or that may 
affect the covenants or the performance of this Indenture; and the Company 
(to the extent it may lawfully do so) hereby expressly waives all benefit or 
advantage of any such law, and covenants that it shall not, by resort to any 
such law, hinder, delay or impede the execution of any power herein granted 
to the Trustee, but shall suffer and permit the execution of every such power 
as though no such law has been enacted.

    4.8  COMPLIANCE STATEMENT; NOTICE OF DEFAULTS.

         (a)  The Company shall deliver to the Trustee within 90 days after 
the end of each fiscal year of the Company an Officer's Certificate stating 
whether or not to the best knowledge of the signers thereof the Company is in 
compliance (without regard to periods of grace or notice requirements) with 
all conditions and covenants under this Indenture, and if the Company shall 
not be in compliance, specifying such non-compliance and the nature and 
status thereof of which such signer may have knowledge.

         (b)  The Company shall file with the Trustee written notice of the 
occurrence of any default or Event of Default within ten days of its becoming 
aware of any such default or Event of Default.

    4.9  TAXES.  Except with respect to immaterial items, the Company shall 
pay or discharge or cause to be paid or discharged, before the same shall 
become delinquent, (i) all taxes, assessments and governmental charges 
(including withholding taxes and any penalties, interest and additions to 
taxes) levied or imposed upon the Company or its subsidiaries or upon the 
income, profits or property of the Company or any such subsidiary and (ii) 
all lawful claims for labor, materials and supplies that, if unpaid, might by 
law become a lien upon the property of the Company or any such subsidiary; 
provided that the Company shall not be required to pay or discharge or cause 
to be paid or discharged any such tax, assessment, charge or claim whose 
amount, applicability or validity is being contested in good faith by 
appropriate proceedings and for which disputed amounts adequate reserves have 
been made.

    4.10 INSURANCE.  The Company shall provide, or cause to be provided, for 
itself and its subsidiaries, insurance (including appropriate self-insurance) 
against loss or damage of the kinds customarily insured against by 
corporations similarly situated and owning like properties, including, but 
not limited to, products liability insurance and public liability insurance, 
with reputable insurers or with the government of the United States of 
America or an agency or instrumentality thereof, in such amounts with such 
deductibles and by such methods as shall be determined in good faith by the 
Company to be appropriate.

                         HOLDERS' LISTS AND REPORTS BY
                                  THE COMPANY

    5.1  HOLDERS' LISTS.  The Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of holders of Notes and shall otherwise comply with Trust Indenture
Act Section 312(a).  If the Trustee is not the Notes registrar, the Company
shall furnish to the Trustee on or before at least seven Business Days preceding
each interest payment date and at such other times as the Trustee may request in
writing a list in such form and as of such date as the Trustee reasonably may
require of the names and addresses of holders of Notes, and the Company shall
otherwise comply with Trust Indenture Act Section 312(a).

    5.2  REPORTS BY COMPANY.  The Company shall deliver to the Trustee within
15 days after it files the same with the Commission, copies of all reports and
information (or copies of such portions of any of the foregoing as the
Commission may by its rules and regulations prescribe), if any, which the
Company is required to file with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act or pursuant to the immediately following sentence.  So long
as at least $5,000,000 aggregate principal amount of Notes remain outstanding,
the Company shall file with the Commission such reports as may be required
pursuant to Section 13 of the Exchange Act in respect of a security registered
pursuant to Section 12 of the Exchange Act, regardless of whether the Company is
otherwise required to file such reports.  If the Company is not subject to the
reporting requirements of Section 13 or 15(d) of the Exchange Act (or otherwise
required to file reports pursuant to the immediately preceding sentence), the
Company shall deliver to the Trustee, within 15 days after it would have been
required to file such information with the Commission were it required to do so,
annual and quarterly financial statements, including any notes thereto (and, in
the case of a fiscal year end, an auditors' report by an independent certified
public accounting firm of established national reputation), and a "Management's
Discussion and Analysis of Financial Condition and Results of Operations," in
each case substantially equivalent to that which it would have been required to
include in such quarterly or annual reports, information, documents or other
reports if it had been subject to the requirements of Section 13 or 15(d) of the
Exchange Act.  The Company shall provide copies of the foregoing materials to
the Holders to the extent required by the Trust Indenture Act once this
Indenture has been qualified.  The Company shall also comply with the other
provisions of the Trust Indenture Act Section 314(a).

    Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the 


                                      40

<PAGE>

Company's compliance with any of its covenants hereunder (as to which the 
Trustee is entitled to rely exclusively on Officers' Certificates).

                            DEFAULTS AND REMEDIES

    6.1  EVENTS OF DEFAULT.  In case one or more of the following Events of
Default (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body) shall have occurred and be continuing:

         (a)  any default in the payment of the principal of or premium, if
    any, on the Notes when due at maturity, upon redemption or otherwise,
    including failure by the Company to purchase the Notes when required under
    Section 3.5 (whether or not such payment shall be prohibited by Article XV
    of this Indenture); or

         (b)  any default in the payment of any installment of interest on the
    Notes as and when the same shall become due and payable (whether or not
    such payment shall be prohibited by Article XV of this Indenture), and
    continuance of such default for a period of 30 days; or

         (c)  a failure on the part of the Company duly to observe or perform
    any other covenants or agreements on the part of the Company in this
    Indenture (other than a default in the performance or breach of a covenant
    or agreement that is specifically dealt with elsewhere in this Section 6.1)
    that continues for a period of 60 days after the date on which written
    notice of such failure, requiring the Company to remedy the same, shall
    have been given to the Company by the Trustee, or to the Company and a
    Responsible Officer of the Trustee, by the holders of at least 25% in
    aggregate principal amount of the Notes at the time outstanding determined
    in accordance with Section 8.4; or

         (d)  an event of default occurs under any mortgage, indenture or
    instrument under which there may be issued or by which there may be secured
    or evidenced any indebtedness for money borrowed by the Company or any of
    its subsidiaries (or the payment of which is guaranteed by the Company or
    any of its subsidiaries), whether such indebtedness or guarantee now exists
    or shall be created after the date hereof, which default (i) is caused by a
    failure to pay principal or interest on such indebtedness (a "Payment
    Default") at final maturity or (ii) results in the acceleration of such
    indebtedness prior to its expressed maturity and, in each case, the
    principal amount of 


                                      41

<PAGE>

    such indebtedness, together with the principal amount of any other such 
    indebtedness under which there has been a Payment Default or the maturity 
    of which has been so accelerated, aggregates $10 million or more and such 
    Payment Default shall not have been cured or such acceleration rescinded 
    within a 10 day period;

         (e)  any final judgments or decrees shall be entered by a court of
    competent jurisdiction against the Company or any subsidiary involving
    liabilities of $20 million or more (singly or in the aggregate) (after
    deducting the portion of such liabilities accepted by a reputable insurance
    company) and such final judgments or decrees shall not have been vacated,
    discharged, satisfied or stayed pending appeal within 60 days from the
    entry thereof;

         (f)  the Company or any "Significant Subsidiary" (as such term is
    defined in Rule 1-02 of Regulation S-X under the Securities Act) of the
    Company shall commence a voluntary case or other proceeding seeking
    liquidation, reorganization or other relief with respect to itself or its
    debts under any bankruptcy, insolvency or other similar law now or
    hereafter in effect, or seeking the appointment of a trustee, receiver,
    liquidator, custodian or other similar official of it or any substantial
    part of its property, or shall consent to any such relief or to the
    appointment of or taking possession by any such official in an involuntary
    case or other proceeding commenced against it or shall make a general
    assignment for the benefit of creditors or shall fail generally to pay its
    debts as they become due; or

         (g)  an involuntary case or other proceeding shall be commenced
    against the Company or any Significant Subsidiary of the Company seeking
    liquidation, reorganization or other relief with respect to it or its debts
    under any bankruptcy, insolvency or other similar law now or hereafter in
    effect or seeking the appointment of a trustee, receiver, liquidator,
    custodian or other similar official of it or any substantial part of its
    property, and such involuntary case or other proceeding shall remain
    undismissed and unstayed for a period of 60 consecutive days;

then, and in each and every such case (other than an Event of Default specified
in Section 6.1(f) or (g)), unless the principal of all of the Notes shall have
already become due and payable, either the Trustee or the holders of not less
than 25% in aggregate principal amount of the Notes then outstanding hereunder
determined in accordance with Section 8.4, by notice in writing to the Company
(and to the Trustee if given by Holders), may declare the principal of, premium,
if any, on the Notes and the interest accrued thereon to be due and payable
immediately, and upon any such declaration the same shall become and shall be
immediately due and payable, anything in this Indenture or in the Notes
contained to the contrary notwithstanding.  If an Event of Default 


                                      42

<PAGE>

specified in Section 6.1(f) or (g) occurs and is continuing, the principal 
of, premium, if any, all the Notes and the interest accrued thereon shall be 
immediately due and payable.  The foregoing provisions are subject to the 
conditions that if, at any time after the principal of the Notes shall have 
been so declared or become due and payable, and before any judgment or decree 
for the payment of the monies due shall have been obtained or entered as 
hereinafter provided, the Company shall pay or shall deposit with the Trustee 
a sum sufficient to pay all matured installments of interest upon all Notes 
and the principal of and premium, if any, on any and all Notes that shall 
have become due otherwise than by acceleration (with interest on overdue 
installments of interest (to the extent that payment of such interest is 
enforceable under applicable law) and on such principal and premium, if any, 
at the rate borne by the Notes, to the date of such payment or deposit) and 
amounts due to the Trustee pursuant to Section 7.7, and if any and all 
defaults under this Indenture, other than the nonpayment of principal of, 
premium, if any, and accrued interest on Notes that shall have become due by 
acceleration, shall have been cured or waived pursuant to Section 6.7, then 
and in every such case the holders of a majority in aggregate principal 
amount of the Notes then outstanding, by written notice to the Company and to 
the Trustee, may waive all defaults or Events of Default and rescind and 
annul such declaration and its consequences; but no such waiver or rescission 
and annulment shall extend to or shall affect any subsequent default or Event 
of Default, or shall impair any right consequent thereto.  The Company shall 
notify a Responsible Officer of the Trustee, promptly upon becoming aware 
thereof, of any Event of Default.

    In the event the payment of the Notes is accelerated pursuant to this
Section 6.1, the Company or the Trustee shall promptly notify the holders of the
Designated Senior Indebtedness or the Bank Representative.  The Company may not
pay the Notes upon such acceleration until at least five (5) business days
following receipt of notice of such acceleration by the Bank Representative or
any holder of Designated Senior Indebtedness and, thereafter, the Company may
pay the Notes only if so permitted by the provisions of Article XV hereof.

    In case the Trustee shall have proceeded to enforce any right under this
Indenture and such proceedings shall have been discontinued or abandoned because
of such waiver or rescission and annulment or for any other reason or shall have
been determined adversely to the Trustee, then and in every such case the
Company, the holders of Notes and the Trustee shall be restored respectively to
their several positions and rights hereunder, and all rights, remedies and
powers of the Company, the holders of Notes and the Trustee shall continue as
though no such proceeding had been taken.

    6.2  PAYMENTS OF NOTES ON DEFAULT; SUIT THEREFOR.  The Company covenants
that (a) in case default shall be made in the payment of any installment of
interest upon any of the Notes as and when the same shall become due and
payable, and such default shall have continued for a 


                                      43

<PAGE>

period of 45 days, or (b) in case default shall be made in the payment of the 
principal of or premium, if any, on any of the Notes as and when the same 
shall have become due and payable, whether at maturity of the Notes or in 
connection with any redemption, by declaration or otherwise, then, upon 
demand of the Trustee, the Company shall pay to the Trustee, for the benefit 
of the holders of the Notes, the whole amount that then shall have become due 
and payable on all such Notes for principal, premium, if any, or interest, or 
both, as the case may be, with interest upon the overdue principal, premium, 
if any, and (to the extent that payment of such interest is enforceable under 
applicable law) upon the overdue installments of interest at the rate borne 
by the Notes; and, in addition thereto, such further amount as shall be 
sufficient to cover the costs and expenses of collection, including 
reasonable compensation to the Trustee, its agents, attorneys and counsel, 
and any expenses or liabilities incurred by the Trustee hereunder other than 
through its negligence or bad faith.  Until such demand by the Trustee, the 
Company may pay the principal of and premium, if any, and interest on the 
Notes to the registered holders, whether or not the Notes are overdue.

    In case the Company shall fail forthwith to pay such amounts upon such
demand, the Trustee, in its own name and as trustee of an express trust, shall
be entitled and empowered to institute any actions or proceedings at law or in
equity for the collection of the sums so due and unpaid and may prosecute any
such action or proceeding to judgment or final decree, and may enforce any such
judgment or final decree against the Company or any other obligor on the Notes
and collect in the manner provided by law out of the property of the Company or
any other obligor on the Notes wherever situated the monies adjudged or decreed
to be payable.

    In the case there shall be pending proceedings for the bankruptcy or for
the reorganization of the Company or any other obligor on the Notes under Title
11 of the United States Code or any other applicable law, or in case a receiver,
assignee or trustee in bankruptcy or reorganization, liquidator, sequestrator or
similar official shall have been appointed for or taken possession of the
Company or such other obligor, the property of the Company or such other
obligor, or in the case of any other judicial proceedings relative to the
Company or such other obligor upon the Notes, or to the creditors or property of
the Company or such other obligor, the Trustee, irrespective of whether the
principal of the Notes shall then be due and payable as therein expressed or by
declaration or otherwise and irrespective of whether the Trustee shall have made
any demand pursuant to the provisions of this Section 6.2, shall be entitled and
empowered, by intervention in such proceedings or otherwise, to file and prove a
claim or claims for the whole amount of principal, premium, if any, and interest
owing and unpaid in respect of the Notes and, in case of any judicial
proceedings, to file such proofs of claim and other papers or documents as may
be necessary or advisable in order to have the claims of the Trustee and of the
Holders allowed in such judicial proceedings relative to the Company or any
other obligor on the Notes, its or their creditors, or its or their property and
to 


                                      44

<PAGE>

collect and receive any monies or other property payable or deliverable on 
any such claims and to distribute the same after the deduction of any amounts 
due the Trustee under Section 7.7; and any receiver, assignee or trustee in 
bankruptcy or reorganization, liquidator, custodian or similar official is 
hereby authorized by each of the Holders to make such payments to the Trustee 
and, in the event that the Trustee shall consent to the making of such 
payments directly to the Holders, to pay to the Trustee any amount due it for 
reasonable compensation, expenses, advances and disbursements, including 
counsel fees incurred by it up to the date of such distribution.  To the 
extent that such payment of reasonable compensation, expenses, advances and 
disbursements out of the estate in any such proceedings shall be denied for 
any reason, payment of the same shall be secured by a lien on, and shall be 
paid out of, any and all distributions, dividends, monies, securities and 
other property that the holders of the Notes may be entitled to receive in 
such proceedings, whether in liquidation or under any plan of reorganization 
or arrangement or otherwise.

    Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or adopt on behalf of any Holder any plan of
reorganization or arrangement affecting the Notes or the rights of any Holder,
or to authorize the Trustee to vote in respect of the claim of any Holder in any
such proceeding.

    All rights of action and of asserting claims under this Indenture, or under
any of the Notes, may be enforced by the Trustee without the possession of any
of the Notes or the production thereof on any trial or other proceeding relative
thereto, and any such suit or proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of
judgment shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the holders of the Notes.

    In any proceedings brought by the Trustee (and in any proceedings involving
the interpretation of any provision of this Indenture to which the Trustee shall
be a party), the Trustee shall be held to represent all the holders of the
Notes, and it shall not be necessary to make any holders of the Notes parties to
any such proceedings.

    6.3  APPLICATION OF MONIES COLLECTED BY TRUSTEE.  Any monies collected by
the Trustee pursuant to this Article VI shall be applied in the order following,
at the date or dates fixed by the Trustee for the distribution of such monies,
upon presentation of the several Notes and stamping thereon the payment, if only
partially paid, and upon surrender thereof, if fully paid:

    7.7;


                                      45

<PAGE>

         Second:  Subject to the provisions of Article XV, in case the
    principal of the outstanding Notes shall not have become due and be unpaid,
    to the payment of interest on the Notes in default in the order of the
    maturity of the installments of such interest, with interest (to the extent
    that such interest has been collected by the Trustee) upon the overdue
    installments of interest at the rate borne by the Notes, such payments to
    be made ratably to the persons entitled thereto; and

         Third:  Subject to the provisions of Article XV, in case the principal
    of the outstanding Notes shall have become due, by declaration or
    otherwise, and be unpaid, to the payment of the whole amount then holding
    and unpaid upon the Notes for principal, premium, if any, and interest,
    with interest on the overdue principal and premium, if any, and (to the
    extent that such interest has been collected by the Trustee) upon overdue
    installments of interest at the rate borne by the Notes; and in case such
    monies shall be insufficient to pay in full the whole amounts so due and
    unpaid upon the Notes, then to the payment of such principal, premium, if
    any, and interest without preference or priority of principal and premium,
    if any, over interest, or of interest over principal and premium, if any,
    or of any installment of interest over any other installment of interest,
    or of any Note over any other Note, ratably to the aggregate of such
    principal and premium, if any, and accrued and unpaid interest.

    6.4  PROCEEDINGS BY HOLDER.  No holder of any Note shall have any right by
virtue of or by availing of any provision of this Indenture to institute any
suit, action or proceeding in equity or at law upon or under or with respect to
this Indenture, or for the appointment of a receiver, trustee, liquidator,
custodian or other similar official, or for any other remedy hereunder, unless
such holder previously shall have given to the Trustee written notice of an
Event of Default and of the continuance thereof, as hereinbefore provided, and
unless also the holders of not less than 25% in aggregate principal amount of
the Notes then outstanding shall have made written request upon the Trustee to
institute such action, suit or proceeding in its own name as Trustee hereunder
and shall have offered to the Trustee such reasonable indemnity as it may
require against the costs, expenses and liabilities to be incurred therein or
thereby, and the Trustee for 60 days after its receipt of such notice, request
and offer of indemnity, shall have neglected or refused to institute any such
action, suit or proceeding, and no direction inconsistent with such written
request shall have been given to the Trustee pursuant to Section 6.7; it being
understood and intended, and being expressly covenanted by the taker and holder
of every Note with every other taker and holder and the Trustee, that no one or
more holders of Notes shall have any right in any manner whatever by virtue of
or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other holder of Notes, to obtain or seek to obtain
priority over or preference to any other such holder or to enforce any right
under this Indenture, except in the manner herein provided and for the equal,
ratable and common benefit 


                                      46

<PAGE>

of all holders of Notes (except as otherwise provided herein).  For the 
protection and enforcement of this Section 6.4, each and every Holder and the 
Trustee shall be entitled to such relief as can be given either at law or in 
equity.

    Notwithstanding any other provision of this Indenture and any provision of
any Note, the right of any holder of any Note to receive payment of the
principal of, premium, if any, and interest on such Note, on or after the
respective due dates expressed in such Note, or to institute suit for the
enforcement of any such payment on or after such respective dates against the
Company shall not be impaired or affected without the consent of such holder
except as otherwise set forth herein.

    Anything in this Indenture or the Notes to the contrary notwithstanding,
the holder of any Note, without the consent of either the Trustee or the holder
of any other Note, in his own behalf and for his own benefit, may enforce, and
may institute and maintain any proceeding suitable to enforce, his rights of
conversion as provided herein.

    6.5  PROCEEDINGS BY TRUSTEE.  In case of an Event of Default, the Trustee
may in its discretion proceed to protect and enforce the rights vested in it by
this Indenture by such appropriate judicial proceedings as the Trustee shall
deem most effectual to protect and enforce any of such rights, either by suit in
equity or by action at law or by proceeding in bankruptcy or otherwise, whether
for the specific enforcement of any covenant or agreement contained in this
Indenture or in aid of the exercise of any power granted in this Indenture or to
enforce any other legal or equitable right vested in the Trustee by this
Indenture or by law.

    6.6  REMEDIES CUMULATIVE AND CONTINUING.  Except as provided in Section
2.6, all powers and remedies given by this Article VI to the Trustee or to the
Holders shall, to the extent permitted by law, be deemed cumulative and not
exclusive of such powers and remedies or of any other powers and remedies
available to the Trustee or the holders of the Notes, by judicial proceedings or
otherwise, to enforce the performance or observance of the covenants and
agreements contained in this Indenture, and no delay or omission of the Trustee
or of any holder of any of the Notes to exercise any right or power accruing
upon any default or Event of Default occurring and continuing as aforesaid shall
impair any such right or power or shall be construed to be a waiver of any such
default or any acquiescence therein; and, subject to the provisions of Section
6.4, every power and remedy given by this Article VI or by law to the Trustee or
to the Holders may be exercised from time to time, and as often as shall be
deemed expedient, by the Trustee or by the Holders.

    6.7  DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY MAJORITY OF
HOLDERS.  The holders of a majority in aggregate principal amount of the Notes
at the time outstanding 


                                      47

<PAGE>

(determined in accordance with Section 8.4) shall have the right to direct 
the time, method and place of conducting any proceeding for any remedy 
available to the Trustee or exercising any trust or power conferred on the 
Trustee; provided that (a) such direction shall not be in conflict with any 
rule of law or with this Indenture and (b) the Trustee may take any other 
action deemed proper by the Trustee that is not inconsistent with such 
direction.  The holders of a majority in aggregate principal amount of the 
Notes at the time outstanding (determined in accordance with Section 8.4) may 
on behalf of the holders of all of the Notes waive any past default or Event 
of Default hereunder and its consequences except (i) a default in the payment 
of interest or premium, if any, on, or the principal of, the Notes, (ii) a 
failure by the Company to convert any Notes into Common Stock or (iii) a 
default in respect of a covenant or provision hereof that under Article X 
cannot be modified or amended without the consent of the holders of all Notes 
then outstanding.  Whenever any default or Event of Default hereunder shall 
have been waived as permitted by this Section 6.7, said default or Event of 
Default shall for all purposes of the Notes and this Indenture be deemed to 
have been cured and to be not continuing and the Company, the Trustee and the 
holders of the Notes shall be restored to their former positions and rights 
hereunder; but no such waiver shall extend to any subsequent or other default 
or Event of Default or impair any right consequent thereon.

    6.8  NOTICE OF DEFAULTS.  The Trustee shall, within 90 days after the
occurrence of a default, mail to all Holders, as the names and addresses of such
holders appear upon the Note register, notice of all defaults known to a
Responsible Officer, unless such defaults shall have been cured or waived before
the giving of such notice; provided that, except in the case of default in the
payment of the principal of, premium, if any, or interest on any of the Notes,
the Trustee shall be protected in withholding such notice if and so long as a
trust committee of directors and/or Responsible Officers of the Trustee in good
faith determine that the withholding of such notice is in the interests of the
Holders.

    6.9  UNDERTAKING TO PAY COSTS.  All parties to this Indenture agree, and
each holder of any Note by his acceptance thereof shall be deemed to have
agreed, that any court may, in its discretion, require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees and expenses, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses
made by such party litigant; provided that the provisions of this Section 6.9
shall not apply to any suit instituted by the Trustee, to any suit instituted by
any Holder or group of Holders holding in the aggregate more than 10% in
principal amount of the Notes at the time outstanding determined in accordance
with Section 8.4 or to any suit instituted by any Holder for the enforcement of
the payment of the principal of, premium, if any, or interest on any Note on 


                                      48

<PAGE>

or after the due date expressed in such Note or to any suit for the 
enforcement of the right to convert any Note in accordance with the 
provisions of Article XIV.

                                     VII

    7.1  DUTIES AND RESPONSIBILITIES OF TRUSTEE.

         (a)  If an Event of Default has occurred and is continuing, the
Trustee shall exercise the rights and powers vested in it by this Indenture and

exercise or use under the circumstances in the conduct of such person's own
affairs.

         (b)  Except during the continuance of an Event of Default:

              (1)  the Trustee need perform only those duties that are

              (2)  in the absence of bad faith on its part, the Trustee may
         conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements
         of this Indenture; provided that in the case of any such certificates
         or opinions that by any provision hereof are specifically required to
         be furnished to the Trustee, the Trustee shall be under a duty to
         examine the same to determine whether or not they conform to the
         requirements of this Indenture (but need not confirm or investigate
         the accuracy of mathematical calculations or other facts stated
         therein).  

         (c)  The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act or its own willful

         (b) of this Section 7.1;

              (2)  the Trustee shall not be liable for any error of judgment
         made in good faith by an officer of the Trustee unless it is proved

         and


                                      49

<PAGE>

              (3)  the Trustee shall not be liable with respect to any action
         it takes or omits to take in good faith in accordance with a direction

or power or extend or risk its own funds or otherwise incur any financial
liability unless it receives indemnity satisfactory to it against any loss,
liability or expense.

report dated as of such May 15 that complies with Trust Indenture Act Section
313(a).  The Trustee also shall comply with Trust Indenture Act Sections 313(b)
and 313(c).

    The Company shall promptly notify the Trustee in writing if the Notes

Trust Indenture Act Section 313(d), filed with the Commission and each stock
exchange, if any, on which the Notes are listed.

    7.3  RELIANCE ON DOCUMENTS, OPINIONS, ETC.  Except as otherwise provided in
Section 7.1:

         (a)  The Trustee may rely and shall be protected in acting upon any
    resolution, certificate, statement, instrument, opinion, report, notice,
    request, consent, order, bond, debenture, coupon or other paper or document
    believed by it in good faith to be genuine and to have been signed or
    presented by the proper party or parties;

         (b)  Any request, direction, order or demand of the Company mentioned
    herein shall be sufficiently evidenced by an Officers' Certificate (unless
    other evidence in respect thereof be herein specifically prescribed or

    Directors may be evidenced to the Trustee by a copy thereof certified by

    negligence on the part of any agent or attorney appointed by it with due
    care hereunder; no Depositary, Custodian or paying agent who is not the
    Trustee shall be deemed an agent of the Trustee, and the Trustee (in its
    capacity as Trustee) shall not be responsible for any act or omission by
    any such Depositary, Custodian or paying agent;

         (e)  The Trustee shall be under no obligation to exercise any of the
    rights or powers vested in it by the Indenture at the request or direction
    of any of the holders pursuant to this Indenture unless such holders have
    offered the Trustee reasonable security or indemnity against the costs,
    expenses and liabilities that would be incurred by it in compliance with
    such request or direction.

         (f)  Subject to the provisions of Section 7.1(c), the Trustee shall
    not be liable for any action it takes or omits to take in good faith that
    it believes to be authorized or within its rights or powers;

         (g)  In connection with any request to transfer or exchange any Note,
    the Trustee may request a direction (in the form of an Officers'
    Certificate) from the Company and an Opinion of Counsel with respect to
    compliance with any restrictions on transfer or exchange imposed by this
    Indenture, the Securities Act, other applicable law or the rules and
    regulations of any exchange on which the Notes or the capital stock may be
    traded, and the Trustee may rely and shall be protected in acting upon such
    direction and in accordance with such Officers' Certificate and Opinion of
    Counsel;

         (h)  The Trustee may rely and shall be fully protected in acting upon
    the determination and notice by the Company of the Conversion Price; and

         (i)  The Trustee shall not be deemed to have knowledge of any Event of

                                      51

<PAGE>

         (j)  the Trustee shall not be bound to make any investigation into the
    facts or matters stated in any resolution, certificate, statement,
    instrument, opinion, report, notice, request, direction, consent, order,
    bond, debenture, note, other evidence of indebtedness or other paper or
    document, but the Trustee, in its discretion, may make such further inquiry
    or investigation into such facts or matters as it may see fit, and, if the
    Trustee shall determine to make such further inquiry or investigation, it
    shall be entitled to examine the books, records and premises of the
    Company, personally or by agent or attorney at the sole cost of the Company
    and shall incur no liability or additional liability of any kind by reason
    of such inquiry or investigation.

    7.4  NO RESPONSIBILITY FOR RECITALS, ETC.  The recitals contained herein
and in the Notes (except in the Trustee's certificate of authentication) shall
be taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same.  The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Notes.  The Trustee shall not be accountable for the use or application by the
Company of any Notes or the proceeds of any Notes authenticated and delivered by
the Trustee in conformity with the provisions of this Indenture.

    7.5  TRUSTEE, PAYING AGENTS, CONVERSION AGENTS OR REGISTRAR MAY OWN NOTES. 
The Trustee, any paying agent, any conversion agent or any Note registrar, in
its individual or any other capacity, may become the owner or pledgee of Notes
with the same rights it would have if it were not Trustee, paying agent,
conversion agent or Note registrar.

    7.6  MONIES TO BE HELD IN TRUST.  Subject to the provisions of Section
12.4, all monies received by the Trustee shall, until used or applied as herein
provided, be held in trust for the purposes for which they were received.  Money
held by the Trustee in trust hereunder need not be segregated from other funds
except to the extent required by law.  The Trustee shall be under no liability
for interest on any money received by it hereunder except as may be agreed to in
writing from time to time by the Company and the Trustee.

    7.7  COMPENSATION AND EXPENSES OF TRUSTEE.  The Company covenants and
agrees to pay to the Trustee from time to time, and the Trustee shall be
entitled to, such compensation as the Company and the Trustee shall from time to
time agree in writing, for all services rendered by it hereunder in any capacity
(which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust), and the Company shall pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of all persons not
regularly in its employ) except any such expense, disbursement or advance as may
arise from 


                                      52

<PAGE>

its negligence or bad faith.  The Company also covenants to indemnify each of 
the Trustee or any predecessor Trustee in any capacity under this Indenture 
and its agents and any authenticating agent for, and to hold them harmless 
against, any and all loss, liability, damage, claim or expense, including 
taxes (other than taxes based on the income of the Trustee) incurred without 
negligence or bad faith on the part of the Trustee or such agent or 
authenticating agent, as the case may be, and arising out of or in connection 
with the acceptance or administration of this trust or in any other capacity 
hereunder, including the costs and expenses of defending themselves against 
any claim of liability in the premises.  The obligations of the Company under 
this Section 7.7 to compensate or indemnify the Trustee and to pay or 
reimburse the Trustee for expenses, disbursements and advances shall be 
secured by a lien prior to that of the Notes upon all property and funds held 
or collected by the Trustee as such, except funds held in trust for the 
benefit of the holders of particular Notes.  When the Trustee incurs expenses 
or renders services in connection with an Event of Default specified in 
Section 6.1(f) or Section 6.1(g), the expenses (including the reasonable 
charges and expenses of its counsel) and the compensation for the services 
are intended to constitute expenses of administration under any applicable 
Federal or state bankruptcy, insolvency or other similar law. The obligation 
of the Company under this Section shall survive the satisfaction and 
discharge of this Indenture.

    7.8  OFFICERS' CERTIFICATE AS EVIDENCE.  Except as otherwise provided in
Section 7.1, whenever in the administration of the provisions of this Indenture
the Trustee shall deem it necessary or desirable that a matter be proved or
established prior to taking or omitting any action hereunder, such matter
(unless other evidence in respect thereof be herein specifically prescribed)
may, in the absence of negligence or bad faith on the part of the Trustee, be
deemed to be conclusively proved and established by an Officers' Certificate
delivered to the Trustee, and such Officers' Certificate, in the absence of
negligence or bad faith on the part of the Trustee, shall be full warrant to the
Trustee for any action taken or omitted by it under the provisions of this
Indenture upon the faith thereof.

    7.9  CONFLICTING INTERESTS OF TRUSTEE.  In the event that the Trust
Indenture Act is applicable hereto, and if the Trustee has or shall acquire a
conflicting interest within the meaning of Trust Indenture Act Section 310(b)
and there exists an Event of Default hereunder (exclusive of any period of grace
or requirement of notice), the Trustee shall either eliminate such interest or
resign, to the extent and in the manner provided by, and subject to the
provisions of, the Trust Indenture Act and this Indenture.

    7.10 ELIGIBILITY OF TRUSTEE.  There shall at all times be a Trustee
hereunder that shall be a person that satisfies the requirements of Trust
Indenture Act Section 310(a)(1) and Section 310(a)(5) and that has a combined
capital and surplus of at least $50,000,000.  If such person publishes reports
of condition at least annually, pursuant to law or to the requirements of any


                                      53

<PAGE>

supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such person shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.  If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article VII.

    7.11 RESIGNATION OR REMOVAL OF TRUSTEE. 

         (a)  The Trustee may at any time resign by giving written notice of
such resignation to the Company; and the Company shall mail, or cause to be
mailed, notice thereof to the holders of Notes at their addresses as they shall
appear on the Note register.  Upon receiving such notice of resignation, the
Company shall promptly appoint a successor trustee by written instrument, in
duplicate, executed by order of the Board of Directors, one copy of which
instrument shall be delivered to the resigning Trustee and one copy to the
successor trustee. 

         (b)  In case at any time any of the following shall occur:

         (1)  the Trustee shall fail to comply with Section 7.9 after written
    request therefor by the Company or by any Holder who has been a BONA FIDE
    holder of a Note or Notes for at least six months; or

         (2)  the Trustee shall cease to be eligible in accordance with the
    provisions of Section 7.10 and shall fail to resign after written request
    therefor by the Company or by any such Holder; or

         (3)  the Trustee shall become incapable of acting, or shall be
    adjudged bankrupt or insolvent, or a receiver of the Trustee or of its
    property shall be appointed, or any public officer shall take charge or
    control of the Trustee or of its property or affairs for the purpose of
    rehabilitation, conservation or liquidation,

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors, one copy of which instrument shall be delivered to the
Trustee so removed and one copy to the successor trustee or any Holder who has
been a BONA FIDE holder of a Note or Notes for at least six months may, on
behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a
successor trustee.  Such court may thereupon, after such notice, if any, as it
may deem proper and prescribe, remove the Trustee and appoint a successor
trustee.


                                      54

<PAGE>

         (c)  The holders of a majority in aggregate principal amount of the
Notes at the time outstanding may at any time remove the Trustee and nominate a
successor trustee, which shall be deemed appointed as successor trustee unless
within ten days after notice to the Company of such nomination the Company
objects thereto, in which case the Trustee so removed or any Holder, upon the
terms and conditions and otherwise as provided in the next paragraph, may
petition any court of competent jurisdiction for an appointment of a successor
trustee.

         If no successor trustee shall have been so appointed and have accepted
appointment within 60 days after removal or the mailing of such notice of
resignation to the Holders, the Trustee resigning or being removed may petition
any court of competent jurisdiction for the appointment of a successor trustee,
or, in the case of either resignation or removal, any Holder who has been a BONA
FIDE holder of a Note or Notes for at least six months may, on behalf of himself
and all others similarly situated, petition any such court for the appointment
of a successor trustee.  Such court may thereupon, after such notice, if any, as
it may deem proper and prescribe, appoint a successor trustee.

         (d)  Any resignation or removal of the Trustee and appointment of a
successor trustee pursuant to any of the provisions of this Section 7.11 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 7.12.

    7.12 ACCEPTANCE BY SUCCESSOR TRUSTEE.  Any successor trustee appointed as
provided in Section 7.11 shall execute, acknowledge and deliver to the Company
and to its predecessor trustee an instrument accepting such appointment
hereunder, and thereupon, the resignation or removal of the predecessor trustee
shall become effective and such successor trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, duties and
obligations of its predecessor hereunder, with like effect as if originally
named as trustee herein; but on the written request of the Company or of the
successor trustee, the Trustee ceasing to act shall, upon payment of any amounts
then due it pursuant to the provisions of Section 7.7, execute and deliver an
instrument transferring to such successor trustee all the rights and powers of
the Trustee so ceasing to act.  Upon request of any such successor trustee, the
Company shall execute any and all instruments in writing for more fully and
certainly vesting in and confirming to such successor trustee all such rights
and powers.  Any Trustee ceasing to act shall, nevertheless, retain a lien upon
all property and funds held or collected by such trustee as such, except for
funds held in trust for the benefit of holders of particular Notes, to secure
any amounts then due it pursuant to the provisions of Section 7.7.


                                      55

<PAGE>

    No successor trustee shall accept appointment as provided in this Section
7.12 unless at the time of such acceptance such successor trustee shall be
qualified under the provisions of Section 7.9 and eligible under the provisions
of Section 7.10.

    Upon acceptance of appointment by a successor trustee as provided in this
Section 7.12, the Company shall mail or cause to be mailed notice of the
succession of such Trustee hereunder to the holders of Notes at their addresses
as they shall appear on the Note register.  If the Company fails to mail such
notice within ten days after acceptance of appointment by the successor trustee,
the successor trustee shall cause such notice to be mailed at the expense of the
Company.

    7.13 SUCCESSOR, BY MERGER, ETC.  Any corporation into which the Trustee may
be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to all or substantially all of
the corporate trust business of the Trustee, shall be the successor to the
Trustee hereunder, provided such corporation shall be qualified under the
provisions of Section 7.9 and eligible under the provisions of Section 7.10
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.

    7.14 LIMITATION ON RIGHTS OF TRUSTEE AS CREDITOR.  If and when the Trustee
shall be or become a creditor of the Company (or any other obligor upon the
Notes) and the Trust Indenture Act is applicable hereto, the Trustee shall be
subject to the provisions of Trust Indenture Act Section 311(a) or, if
applicable, Trust Indenture Act Section 311(b) regarding the collection of the
claims against the Company (or any such other obligor).

                                         VIII
                                CONCERNING THE HOLDERS

    8.1  ACTION BY HOLDERS.  Whenever in this Indenture it is provided that the
holders of a specified percentage in aggregate principal amount of the Notes may
take any action (including the making of any demand or request, the giving of
any notice, consent or waiver or the taking of any other action), the fact that
at the time of taking any such action, the holders of such specified percentage
have joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by Holders in person or by agent or proxy
appointed in writing, (b) by the record of the holders of Notes voting in favor
thereof at any meeting of Holders duly called and held in accordance with the
provisions of Article IX or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Holders.  Whenever the
Company or the Trustee solicits the taking of any action by the holders of the
Notes, the Company or the Trustee may fix in advance of such solicitation, a
date as the 


                                      56

<PAGE>

record date for determining holders entitled to take such action. The record 
date shall be not more than 15 days prior to the date of commencement of 
solicitation of such action.

    8.2  PROOF OF EXECUTION BY HOLDERS.  Subject to the provisions of Sections
7.1, 7.2 and 9.5, proof of the execution of any instrument by a Holder or by
agent or proxy shall be sufficient if made in accordance with such reasonable
rules and regulations as may be prescribed by the Trustee or in such manner as
shall be satisfactory to the Trustee.  The holding of Notes shall be proved by
the Note register or by a certificate of the Note registrar.

    The record of any Holders' meeting shall be proved in the manner provided
in Section 9.5.

    8.3  WHO ARE DEEMED ABSOLUTE OWNERS.  The Company, the Trustee, any paying
agent, any conversion agent and any Note registrar may deem the person in whose
name such Note shall be registered upon the books of the Company to be, and may
treat such person as, the absolute owner of such Note (whether or not such Note
shall be overdue and notwithstanding any notation of ownership or other writing
thereon) for the purpose of receiving payment of or on account of the principal
of, premium, if any, and interest on such Note, for conversion of such Note and
for all other purposes; and neither the Company nor the Trustee nor any paying
agent nor any conversion agent nor any Note registrar shall be affected by any
notice to the contrary.  All such payments so made to any holder for the time
being, or upon order of such holder, shall be valid and, to the extent of the
sum or sums so paid, effectual to satisfy and discharge the liability for monies
payable upon any such Note.

    The Depositary shall be deemed to be the owner of any global Note for all
purposes, including receipt of notices to Holders and payment of principal of,
premium, if any, and interest on the Notes.  None of the Company, the Trustee
(in its capacity as Trustee), any paying agent or the Note registrar (or 
co-registrar) shall have any responsibility for any aspect of the records 
relating to or payments made on account of beneficial interests of a global 
Note or for maintaining, supervising or reviewing any records relating to 
such beneficial ownership interests; provided that the foregoing shall not 
apply to the Trustee or any other person acting in its capacity as Custodian.

    8.4  COMPANY-OWNED NOTES DISREGARDED.  In determining whether the holders
of the requisite aggregate principal amount of Notes have concurred in any
direction, consent, waiver or other action under this Indenture, Notes that are
owned by the Company or any other obligor on the Notes or by any person directly
or indirectly controlling or controlled by or under direct or indirect common
control with the Company or any other obligor on the Notes shall be disregarded
and deemed not to be outstanding for the purpose of any such determination;


                                      57

<PAGE>

provided that for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, consent, waiver or other action,
only Notes that a Responsible Officer actually knows are so owned shall be so
disregarded.  Notes so owned that have been pledged in good faith may be
regarded as outstanding for the purposes of this Section 8.4 if the pledgee
shall establish to the satisfaction of the Trustee the pledger's right to vote
such Notes and that the pledgee is not the Company, any other obligor on the
Notes or a person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or any such other obligor. 
In the case of a dispute as to such right, any decision by the Trustee taken
upon the advice of counsel shall be full protection to the Trustee.  Upon
request of the Trustee, the Company shall furnish to the Trustee promptly an
Officers' Certificate listing and identifying all Notes, if any, known by the
Company to be owned or held by or for the account of any of the above described
persons; and subject to Section 7.1, the Trustee shall be entitled to accept
such Officers' Certificate as conclusive evidence of the facts therein set forth
and of the fact that all Notes not listed therein are outstanding for the
purpose of any such determination.

    8.5  REVOCATION OF CONSENTS, FUTURE HOLDERS BOUND.  At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 8.1, of
the taking of any action by the holders of the percentage in aggregate principal
amount of the Notes specified in this Indenture in connection with such action,
any holder of a Note that is shown by the evidence to be included in the Notes
the holders of which have consented to such action may, by filing written notice
with the Trustee at its Corporate Trust Office and upon proof of holding as
provided in Section 8.2, revoke such action so far as concerns such Note. 
Except as aforesaid, any such action taken by the holder of any Note shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Note and of any Notes issued in exchange or substitution therefor,
irrespective of whether any notation in regard thereto is made upon such Note or
any Note issued in exchange or substitution therefor.

                                          IX

                               SUPPLEMENTAL INDENTURES

    10.1 SUPPLEMENTAL INDENTURES WITHOUT CONSENT OF HOLDERS.  The Company, when
authorized by a Board Resolution, and the Trustee may from time to time and at
any time enter into an indenture or indentures supplemental hereto for one or
more of the following purposes:

         (a)  to make provision with respect to the conversion rights of the
    holders of Notes pursuant to the requirements of Section 14.6;

         (b)  subject to Article XV, to convey, transfer, assign, mortgage or
    pledge to the Trustee as security for the Notes, any property or assets;

         (c)  to evidence the succession of another person to the Company, or
    successive successions, and the assumption by the Successor Company of the
    covenants, agreements and obligations of the Company pursuant to Article
    XI;

         (d)  to add to the covenants of the Company such further covenants,
    restrictions or conditions as the Board of Directors and the Trustee shall
    consider to be for the benefit of the holders of Notes and to make the
    occurrence, or the occurrence and continuance, of a default in any such
    additional covenants, restrictions or conditions a default or an Event of
    Default permitting the enforcement of all or any of the several remedies
    provided in this Indenture as herein set forth; provided that in respect of
    any such additional covenant, restriction or condition, such supplemental
    indenture may provide for a particular period of grace after default (which
    period may be shorter or longer than that allowed in the case of other
    defaults) or may provide for an immediate enforcement upon such default or
    may limit the remedies available to the Trustee upon such default;

         (e)  to provide for the issuance under this Indenture of Notes in
    coupon form (including Notes registrable as to principal only) and to
    provide for exchangeability of such Notes with the Notes issued hereunder
    in fully registered form and to make all appropriate changes for such
    purpose;

         (f)  to cure any ambiguity or to correct or supplement any provision
    contained herein or in any supplemental indenture that may be defective or
    inconsistent with any other provision contained herein or in any
    supplemental indenture, or to make such other provisions in regard to
    matters or questions arising under this Indenture that shall not adversely
    affect the interests of the holders of the Notes;


                                      61

<PAGE>

         (g)  to evidence and provide for the acceptance of appointment
    hereunder by a successor Trustee with respect to the Notes; or

         (h)  to modify, eliminate or add to the provisions of this Indenture
    to such extent necessary to effect the qualification of this Indenture
    under the Trust Indenture Act (if applicable), or under any similar federal
    statute hereafter enacted (if applicable).

of any such supplemental indenture, to make any further appropriate agreements
and stipulations that may be therein contained and to accept the conveyance,
transfer and assignment of any property thereunder, but the Trustee shall not be
obligated to, but may in its discretion, enter into any supplemental indenture
that affects the Trustee's own rights, duties or immunities under this Indenture
or otherwise.

    Any supplemental indenture authorized by the provisions of this Section
10.1 may be executed by the Company and the Trustee without the consent of the
holders of any of the Notes at the time outstanding, notwithstanding any of the
provisions of Section 10.2.

(evidenced as provided in Article VIII) of the holders of not less than a
majority in aggregate principal amount of the Notes at the time outstanding, the

for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or any supplemental
indenture or of modifying in any manner the rights of the holders of the Notes;
provided that, without the consent of the holders of all Notes then outstanding,
no such supplemental indenture shall (i) extend the fixed maturity of any Note,
or reduce the rate or extend the time of payment of interest thereon, or reduce
the principal amount thereof or premium, if any, thereon or reduce any amount
payable on redemption thereof, alter the obligation of the Company to redeem the
Notes at the option of the holder upon the occurrence of a Change of Control or
impair or affect the right of any Holder to institute suit for the payment
thereof or make the principal thereof or interest or premium, if any, thereon
payable in any coin or currency other than that provided in the Notes, modify
the subordination provisions in a manner adverse to the holders of the Notes, or
impair the right to convert the Notes into Common Stock subject to the terms set
forth herein without the consent of the holder of each Note so affected or (ii)
reduce the aforesaid percentage of Notes, the holders of which are required to
consent to any such supplemental indenture.

    Upon the request of the Company, accompanied by a copy of a Board
Resolution certified by its Secretary or Assistant Secretary authorizing the
execution of any such 


                                      62

<PAGE>

supplemental indenture, and upon the filing with the Trustee of evidence of 
the consent of Holders as aforesaid, the Trustee shall join with the Company 
in the execution of such supplemental indenture unless such supplemental 
indenture affects the Trustee's own rights, duties or immunities under this 
Indenture or otherwise, in which case the Trustee may in its discretion, but 
shall not be obligated to, enter into such supplemental indenture.

    It shall not be necessary for the consent of the Holders under this Section
10.2 to approve the particular form of any proposed supplemental indenture, but
it shall be sufficient if such consent shall approve the substance thereof.

    10.3 EFFECT OF SUPPLEMENTAL INDENTURES.  Any supplemental indenture
executed pursuant to the provisions of this Article X shall comply with the
Trust Indenture Act, as then in effect, if such supplemental indenture is then
required to so comply.  Upon the execution of any supplemental indenture
pursuant to the provisions of this Article X, this Indenture shall be and be
deemed to be modified and amended in accordance therewith and the respective
rights, limitation of rights, obligations, duties and immunities under this
Indenture of the Trustee, the Company and the holders of Notes shall thereafter
be determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments and all the terms and conditions of any such
supplemental indenture shall be and be deemed to be part of the terms and
conditions of this Indenture for any and all purposes.

    10.4 NOTATION ON NOTES.  Notes authenticated and delivered after the
execution of any supplemental indenture pursuant to the provisions of this
Article X may bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture, but they need not do so.  If the
Company or the Trustee shall determine to add such a notation, new Notes so
modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any modification of this Indenture contained in any such
supplemental indenture may, at the Company's expense, be prepared and executed
by the Company, authenticated by the Trustee (or an authenticating agent duly
appointed by the Trustee pursuant to Section 16.14) and delivered in exchange
for the Notes then outstanding, upon surrender of such Notes then outstanding.

    10.5 EVIDENCE OF COMPLIANCE OF SUPPLEMENTAL INDENTURE TO BE FURNISHED
TRUSTEE.  The Trustee shall be furnished with and, subject to the provisions of
Sections 7.1 and 7.2, may rely upon an Officers' Certificate and an Opinion of
Counsel as conclusive evidence that any supplemental indenture executed pursuant
hereto complies with the requirements of this Article X.

                                  TRANSFER AND LEASE

    11.1 COMPANY MAY CONSOLIDATE, ETC. ON CERTAIN TERMS.  The Company shall not
consolidate with or merge with or into, or convey, transfer or lease all or
substantially all of its assets (determined on a consolidated basis) whether in
a single transaction or a series related transactions, to any person unless: (i)
either the Company is the resulting or surviving person or the person to whom
such assets are transferred (in each case, the "Successor Company") or the
Successor Company is a person organized and existing under the laws of the
United States or any State thereof or the District of Columbia, and the
Successor Company (if not the Company) expressly assumes by a supplemental
indenture, executed and delivered to the Trustee, in form satisfactory to the
Trustee, all the obligations of the Company under this Indenture and the Notes,
including the rights pursuant to Article XIV hereof, (ii) immediately after
giving effect to such transaction, no Event of Default has happened and is
continuing and (iii) the Company delivers to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation,
merger or transfer and such supplemental indenture (if any) comply with this
Indenture.

    11.2 SUCCESSOR COMPANY TO BE SUBSTITUTED.  In case of any such
consolidation, merger, sale, conveyance, transfer or lease and upon the
assumption by the Successor Company, by supplemental indenture, executed and
delivered to the Trustee and satisfactory in form to the Trustee, of the due and
punctual payment of the principal of, premium, if any, and interest on all of
the Notes and the due and punctual performance of all of the covenants and
conditions of this Indenture to be performed by the Company, such Successor
Company shall succeed to and be substituted for the Company, with the same
effect as if it had been named herein as the party hereto.  When a Surviving
Person duly assumes all the obligations of the Company pursuant to their
Indenture and the Notes, the predecessor shall be released from all such
obligation.

    11.3 OPINION OF COUNSEL TO BE GIVEN TO TRUSTEE.  The Trustee subject to
Sections 7.1 and 7.2, shall receive an Officers' Certificate and an Opinion of
Counsel as conclusive evidence that any such consolidation, merger, sale,
conveyance, transfer or lease and any such assumption complies with the
provisions of this Article XI.

                       SATISFACTION AND DISCHARGE OF INDENTURE;
                                   UNCLAIMED MONEYS

    12.1 LEGAL DEFEASANCE AND COVENANT DEFEASANCE OF THE NOTES.

         (a)  The Company may, at its option by Board Resolution, at any time,
with respect to the Notes, elect to have either paragraph (b) or paragraph (c)
below be applied to the outstanding Notes upon compliance with the conditions
set forth in paragraph (d).

         (b)  Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (b), the Company shall be deemed to have been
released and discharged from its obligations with respect to the outstanding
Notes on the date the conditions set forth below are satisfied (hereinafter,
"legal defeasance").  For this purpose, such legal defeasance means that the
Company shall be deemed to have paid and discharged the entire indebtedness
represented by the outstanding Notes, which shall thereafter be deemed to be
"outstanding" only for the purposes of the Sections of and matters under this
Indenture referred to in clauses (i) and (ii) below and to have satisfied all
its other obligations under such Notes and this Indenture insofar as such Notes
are concerned, except for the following, which shall survive until otherwise
terminated or discharged hereunder: (i) the rights of holders of outstanding
Notes to receive solely from the trust fund described in paragraph (d) below and
as more fully set forth in such paragraph, payments in respect of the principal
of, premium, if any, and interest on such Notes when such payments are due and
(ii) obligations listed in Section 12.3.

         (c)  Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (c), the Company shall be released and discharged
from its obligations under any covenant contained in Article XI and Section 3.5
with respect to the outstanding Notes on and after the date the conditions set
forth in paragraph (d) are satisfied (hereinafter, "covenant defeasance"), and
the Notes shall thereafter be deemed to be not "outstanding" for the purpose of
any direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder.  For this
purpose, such covenant defeasance means that, with respect to the outstanding
Notes, the Company may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such covenant,
whether directly or indirectly, by reason of any reference elsewhere herein to
any such covenant or by reason of any reference in any such covenant to any
other provision herein or in any other document, and such omission to comply
shall not constitute a Default or an Event of Default under Section 6.1, but,
except as specified above, the remainder of this Indenture and such Notes shall
be unaffected thereby.


                                      65

<PAGE>

         (d)  The following shall be the conditions to application of either
paragraph (b) or paragraph (c) above to the outstanding Notes:

            (i)  The Company shall have irrevocably deposited in trust with
    the Trustee, pursuant to an irrevocable trust and security agreement in
    form and substance satisfactory to the Trustee, cash or U.S. Government
    Obligations maturing as to principal and interest at such times, or a
    combination thereof, in such amounts as are sufficient, without
    consideration of the reinvestment of such interest and after payment of all
    federal, state and local taxes or other charges or assessments in respect
    thereof payable by the Trustee, in the opinion of a nationally recognized
    firm of independent public accountants expressed in a written certification
    thereof (in form and substance reasonably satisfactory to the Trustee)
    delivered to the Trustee, to pay the principal of, premium, if any, and
    interest on the outstanding Notes on the dates on which any such payments
    are due and payable in accordance with the terms of this Indenture and of
    the Notes;

           (ii)  (A)  No Event of Default shall have occurred or be
    continuing on the date of such deposit, and (B) no Default or Event of
    Default under Section 6.1(f) or 6.1(g) shall occur on or before the 123rd
    day after the date of such deposit;

          (iii)  Such deposit shall not result in a Default under this
    Indenture or a breach or violation of, or constitute a default under, any
    other instrument or agreement to which the Company is a party or by which
    it or its property is bound;

           (iv)  In the case of a legal defeasance under paragraph (b) above,
    the Company has delivered to the Trustee an Opinion of Counsel stating that
    (A) the Company has received from, or there has been published by, the
    Internal Revenue Service a ruling or (B) since the date of this Indenture,
    there has been a change in the applicable federal income tax law, in either
    case to the effect that, and based thereon such opinion shall confirm that,
    the holders of the Notes shall not recognize income, gain or loss for
    federal income tax purposes as a result of such deposit, defeasance and
    discharge and shall be subject to federal income tax on the same amounts
    and in the same manner and at the same times as would have been the case if
    such deposit, defeasance and discharge had not occurred; and, in the case
    of a covenant defeasance under paragraph (c) above, the Company shall
    deliver to the Trustee an Officers' Certificate and an Opinion of Counsel,
    in form and substance reasonably satisfactory to the Trustee, to the effect
    that holders of the Notes shall not recognize income, gain or loss for
    federal income tax purposes as a result of such deposit and defeasance and
    shall be subject to federal income tax on the same amounts, in the same
    manner and at the same times as would have been the case if such deposit
    and defeasance had not occurred;


                                      66

            (v)  The holders shall have a perfected security interest under
    applicable law in the cash or U.S. Government Obligations deposited
    pursuant to Section 12.1(d)(i) above;

           (vi)  The Company shall have delivered to the Trustee an Opinion
    of Counsel, in form and substance reasonably satisfactory to the Trustee,
    to the effect that, after the passage of 123 days following the deposit,
    the trust funds shall not be subject to any applicable bankruptcy,
    insolvency, reorganization or similar law affecting creditors' rights
    generally;

          (vii)  Such defeasance shall not cause the Trustee to have a
    conflicting interest with respect to any securities of the Company; and

         (viii)  The Company has delivered to the Trustee an Officers'
    Certificate and an Opinion of Counsel, each stating that all conditions
    precedent specified herein relating to the defeasance contemplated by this
    Section 12.1 have been complied with;

provided, that no deposit under clause (i) shall be effective to terminate the
obligations of the Company under the Notes or this Indenture prior to the
passage of 123 days following such deposit.

    12.2 TERMINATION OF OBLIGATIONS UPON CANCELLATION OF THE NOTES.  In
addition to the Company's rights under Section 12.1, the Company may terminate
all of its obligations under this Indenture (subject to Section 12.3) when:

         (a)  (i) all Notes theretofore authenticated and delivered (other than
    Notes that have been destroyed, lost or stolen and that have been replaced
    or paid as provided in Section 2.6) have been delivered to the Trustee for
    cancellation; and

              (ii) the Company has paid or caused to be paid all other sums
    payable hereunder and under the Notes by the Company; or

         (b)  (i)  the Notes not previously delivered to the Trustee for
    cancellation shall have become due and payable or are by their terms to
    become due and payable within one year or are to be called for redemption
    under arrangements satisfactory to the Trustee upon delivery of notice,
    (ii) the Company shall have irrevocably deposited with the Trustee, as
    trust funds, cash, in an amount sufficient to pay principal of and interest
    on the outstanding Notes, to maturity or redemption, as the case may be,
    (iii) such deposit shall not result in a breach or violation of, or
    constitute a default under, any agreement or instrument pursuant to which
    the Company is a party or by which it or its property is 


                                      67

<PAGE>

    bound and (iv) the Company has delivered to the Trustee an Officers' 
    Certificate and an Opinion of Counsel, each stating that all conditions
    related to such defeasance have been complied with.

    12.3 SURVIVAL OF CERTAIN OBLIGATIONS.  Notwithstanding the satisfaction and
discharge of this Indenture and of the Notes referred to in Section 12.1 or
12.2, the respective obligations of the Company and the Trustee under Sections
2.3, 2.4, 2.5, 2.6, 3.1, 4.2, 5.1, 6.4, 6.9, 7.6, 7.11, 12.5, 12.6, 12.7,
Articles XIV and XV shall survive until the Notes are no longer outstanding, and
thereafter, the obligations of the Company and the Trustee under Sections 6.9,
7.6, 12.5, 12.6 and 12.7 shall survive.  Nothing contained in this Article XII
shall abrogate any of the rights, obligations or duties of the Trustee under
this Indenture.

    12.4 ACKNOWLEDGMENT OF DISCHARGE BY TRUSTEE.  Subject to Section 12.7,
after (i) the conditions of Section 12.1 or 12.2 have been satisfied, (ii) the
Company has paid or caused to be paid all other sums payable hereunder by the
Company and (iii) the Company has delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent referred to in clause (i) above relating to the satisfaction and
discharge of this Indenture have been complied with, the Trustee upon written
request shall acknowledge in writing the discharge of the Company's obligations
under this Indenture except for those surviving obligations specified in Section
12.3.

    12.5 APPLICATION OF TRUST ASSETS.  The Trustee shall hold any cash or U.S.
Government Obligations deposited with it in the irrevocable trust established
pursuant to Section 12.1 or 12.2, as the case may be.  The Trustee shall apply
the deposited cash or the U.S. Government Obligations, together with earnings
thereon in accordance with this Indenture and the terms of the irrevocable trust
agreement established pursuant to Section 12.1 or 12.2, as the case may be, to
the payment of principal of, premium, if any, and interest on the Notes.  The
cash or U.S. Government Obligations so held in trust and deposited with the
Trustee in compliance with Section 12.1 or 12.2, as the case may be, shall not
be part of the trust estate under this Indenture, but shall constitute a
separate trust fund for the benefit of all holders entitled thereto.  Except as
specifically provided herein, the Trustee shall not be requested to invest any
amounts held by it for the benefit of the holders or pay interest on uninvested
amounts to any holder.

    The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 12.1 hereof or Section 12.2 hereof or the
principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the holders of outstanding
Notes.

<PAGE>

    12.6 REPAYMENT TO THE COMPANY; UNCLAIMED MONEY.  Subject to applicable laws
governing escheat of such property, and upon termination of the trust
established pursuant to Section 12.1 hereof or 12.2 hereof, as the case may be,
the Trustee shall promptly pay to the Company upon written request any excess
cash or U.S. Government Obligations held by them.  Additionally, if amounts for
the payment of principal, premium, if any, or interest remains unclaimed for two
years, the Trustee shall, upon written request, pay such amounts back to the
Company forthwith.  Thereafter, all liability of the Trustee with respect to
such amounts shall cease.  After payment to the Company, holders entitled to
such payment must look to the Company for such payment as general creditors
unless an applicable abandoned property law designates another person.

    12.7 REINSTATEMENT.  If the Trustee is unable to apply any cash or U.S.
Government Obligations in accordance with Section 12.1 or 12.2 by reason of any
legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, the Company's obligations under this Indenture and the Notes shall
be revived and reinstated as though no deposit had occurred pursuant to Section
12.1 or 12.2 until such time as the Trustee is permitted to apply all such cash
or U.S. Government Obligations in accordance with Section 12.1 or 12.2, as the
case may be; provided that if the Company makes any payment of principal of,
premium, if any, or interest on any Notes following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the holders of
such Notes to receive such payment from the amounts held by the Trustee.

                                      XIII
                     IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                              OFFICERS AND DIRECTORS

    13.1 INDENTURE AND NOTES SOLELY CORPORATE OBLIGATIONS.  No recourse for the
payment of the principal of, or premium, if any, or interest on any Note, or for
any claim based thereon or otherwise in respect thereof, and no recourse under
or upon any obligation, covenant or agreement of the Company in this Indenture
or in any supplemental indenture or in any Note, or because of the creation of
any indebtedness represented thereby, shall be had against any incorporator,
stockholder, officer or director, as such, past, present or future, of the
Company or of any successor entity, either directly or through the Company or
any successor entity, whether by virtue of any constitution, statute or rule of
law, or by the enforcement of any assessment or penalty or otherwise; it being
expressly understood that all such liability is hereby expressly waived and
released as a condition of, and as a consideration for, the execution of this
Indenture and the issuance of the Notes.

                                 CONVERSION OF NOTES

    14.1 RIGHT TO CONVERT.  Subject to and upon compliance with the provisions
of this Indenture, the holder of any Note shall have the right, at the option of
such holder, at any time after 60 days following the latest date of original
issuance of the Notes and prior to the close of business on October 11, 2002
(except that, with respect to any Note or portion of a Note that shall be called
for redemption or delivered for repurchase, such right shall terminate, except
as provided in the fourth paragraph of Section 14.2, immediately prior to the
close of business on the last Business Day prior to the date fixed for
redemption of such Note or portion of a Note unless the Company shall default in
payment due upon redemption thereof) to convert the principal amount of any such
Note, or any portion of such principal amount that is $1,000 or an integral
multiple thereof, into that number of fully paid and nonassessable shares of
Common Stock (as such shares shall then be constituted) obtained by dividing the
aggregate principal amount of the Notes or portion thereof surrendered for
conversion by the Conversion Price in effect at such time rounded to the nearest
1/100th of a share (with .005 being rolled upward), by surrender of the Note so
to be converted in whole or in part in the manner provided in Section 14.2.  A
Note (or portion thereof) in respect of which a Holder is exercising its option
to require repurchase upon a Change of Control pursuant to Section 3.5 of this
Indenture may only be converted if such Holder withdraws its election to
exercise such redemption option in accordance with the terms of this Indenture.
A holder of Notes is not entitled to any rights of a holder of Common Stock
until such holder has converted such holder's Notes to Common Stock and only to
the extent such Notes are deemed to have been converted to Common Stock under
this Article XIV.

    14.2 EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF COMMON STOCK ON
CONVERSION; NO ADJUSTMENT FOR INTEREST OR DIVIDENDS.  In order to exercise the
conversion privilege with respect to any Note in definitive form, the holder of
any such Note to be converted in whole or in part shall surrender such Note,
duly endorsed, at an office or agency maintained by the Company pursuant to
Section 4.2, accompanied by the funds, if any, required by the penultimate
paragraph of this Section 14.2, and shall give written notice of conversion in
the form provided on the form of Note (or such other notice that is acceptable
to the Company) to the office or agency that the holder elects to convert such
Note or the portion thereof specified in said notice.  Such notice shall also
state the name or names (with address) in which the certificate or certificates
for shares of Common Stock that shall be issuable on such conversion shall be
issued and shall be accompanied by transfer taxes, if required pursuant to
Section 14.7.  Each such Note surrendered for conversion shall, unless the
shares issuable on conversion are to be issued in the name of the holder of such
Note as it appears on the Note register, be duly endorsed by, or be accompanied
by instruments of transfer in form satisfactory to the Company duly executed by,
the holder or his duly authorized attorney.


                                      70

<PAGE>

    In order to exercise the conversion privilege with respect to any 
interest in a global Note, the beneficial holder must complete the 
appropriate instruction form for conversion pursuant to the Depositary's 
book-entry conversion program and follow the other procedures set forth in 
such program.

    As promptly as practicable after satisfaction of the requirements for 
conversion set forth above, subject to compliance with any restrictions on 
transfer if shares issuable on conversion are to be issued in a name other 
than that of the Holder (as if such transfer were a transfer of the Note or 
Notes (or portion thereof) so converted), the Company shall issue and shall 
deliver to such holder at the office or agency maintained by the Company for 
such purpose pursuant to Section 4.2, a certificate or certificates for the 
number of full shares issuable upon the conversion of such Note or portion 
thereof in accordance with the provisions of this Article XIV and a check or 
cash in respect of any fractional interest in respect of a share of Common 
Stock arising upon such conversion, as provided in Section 14.3. In case any 
Note of a denomination greater than $1,000 shall be surrendered for partial 
conversion, and subject to Section 2.3, the Company shall execute and the 
Trustee shall authenticate and make available for delivery to the holder of 
the Note so surrendered, without charge to him, a new Note or Notes in 
authorized denominations in an aggregate principal amount equal to the 
unconverted portion of the surrendered Note.

    Each conversion shall be deemed to have been effected as to any such Note 
(or portion thereof) on the date on which the requirements set forth above in 
this Section 14.2 have been satisfied as to such Note (or portion thereof), 
and the person in whose name any certificate or certificates for shares of 
Common Stock shall be issuable upon such conversion shall be deemed to have 
become on said date the holder of record of the shares represented thereby; 
provided that any such surrender on any date when the stock transfer books of 
the Company shall be closed shall constitute the person in whose name the 
certificates are to be issued as the record holder thereof for all purposes 
on the next succeeding day on which such stock transfer books are open, but 
such conversion shall be at the Conversion Price in effect on the date upon 
which such Note shall have been surrendered.

    Any Note or portion thereof surrendered for conversion during the period 
from the close of business on the record date for any interest payment date 
through the opening of business on the next succeeding interest payment date 
shall (unless such Note or portion thereof being converted shall have been 
called for redemption on a date during the period from the close of business 
on or after any record date to the close of business on the business day 
following the corresponding payment date) be accompanied by payment, in funds 
acceptable to the Company, of an amount equal to the interest otherwise 
payable on such interest payment date on the principal amount being 
converted; provided that no such payment need be made if there shall exist at 
the time of conversion a default in the payment of interest on the Notes.  An 
amount 

                                      71
<PAGE>

equal to such payment shall be paid by the Company on such interest payment 
date to the holder of such Note at the close of business on such record date; 
provided that if the Company shall default in the payment of interest on such 
interest payment date, such amount shall be paid to the person who made such 
required payment.  The interest payment with respect to a Note called for 
redemption on a date during the period from the close of business on or after 
the record date and before the close of business on the business day 
following the corresponding interest payment date shall be payable on the 
corresponding interest payment date to the registered Holder at the close of 
business on that record date (notwithstanding the conversion of such Note 
after the close of business on the record date and before the close of 
business on the corresponding interest payment date) and a Holder who elects 
to convert need not include funds equal to the interest paid. Except as 
provided above in this Section 14.2, no adjustment shall be made for interest 
accrued on any Note converted or for dividends on any shares issued upon the 
conversion of such Note as provided in this Article XIV.

    Upon the conversion of an interest in a global Note, the Trustee, or the 
Custodian at the direction of the Trustee, shall make a notation on such 
global Note as to the reduction in the principal amount represented thereby.

    14.3 CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES.  No fractional shares of 
Common Stock or scrip representing fractional shares shall be issued upon 
conversion of Notes.  If more than one Note shall be surrendered for 
conversion at one time by the same holder, the number of fully paid and 
non-assessable shares of Common Stock issuable upon conversion of a Note 
shall be determined by dividing the aggregate principal amount of the Note or 
portion thereof surrendered for conversion by the Conversion Price in effect 
at such time.  The aggregate number of shares of Common Stock issuable upon 
conversion shall be rounded to the nearest 1/100th of a share (with .005 
being rolled upward).  If any fractional share of stock would be issuable 
upon the conversion of any Note or Notes, the Company shall make an 
adjustment therefor in cash at the current market value thereof.  The current 
market value of a share of Common Stock shall be determined by multiplying 
the fractional share by the Closing Price on the Trading Day immediately 
preceding the date on which the Notes (or specified portions thereof) are 
deemed to have been converted.

    14.4 CONVERSION PRICE.  The Conversion Price shall be as specified in the 
forms of Notes (herein called the "Conversion Price") attached as Exhibits A, 
B and C hereto, subject to adjustment as provided in this Article XIV.

    14.5 ADJUSTMENT OF CONVERSION PRICE.  The Conversion Price shall be 
adjusted from time to time by the Company as follows:

                                      72
<PAGE>

         (a)  In case the Company shall (i) pay a dividend or make a 
    distribution on its Common Stock in shares of its Common Stock, (ii) 
    subdivide or split its outstanding Common Stock into a greater number of 
    shares, (iii) combine its outstanding Common Stock into a smaller number 
    of shares or (iv) issue any shares of capital stock by reclassification 
    of its Common Stock, the conversion price in effect immediately prior 
    thereto shall be adjusted so that the Holder of any Notes thereafter 
    surrendered for conversion shall be entitled to receive the number of 
    shares of Common Stock of the Company which such Holder would have owned 
    or have been entitled to receive after the occurrence of any of the 
    events described above had such Notes been surrendered for conversion 
    immediately prior to the occurrence of such event or the record date 
    therefor, which is earlier. An adjustment made pursuant to this 
    subsection (a) shall become effective immediately after the close of 
    business on the record date for determination of stockholders entitled 
    to receive such dividend or distribution in the case of a dividend or 
    distribution (except as provided in Section 14.5(c)) and shall become 
    effective immediately after the close of business on the effective date 
    in the case of a subdivision, split, combination or reclassification.  
    Any shares of Common Stock issuable in payment of a dividend shall be 
    deemed to have been issued immediately prior to the close of business on 
    the record date for such dividend for purposes of calculating the number 
    of outstanding shares of Common Stock under this Section 14.5(a) and 
    Section 14.5(b).
    
         (b)  In case the Company shall issue rights, options or warrants to 
    all holders of its outstanding shares of Common Stock entitling them 
    (for a period expiring within 45 days after the date fixed for 
    determination of stockholders entitled to receive such rights, options 
    or warrants) to subscribe for or purchase shares of Common Stock at a 
    price per share less than the Current Market Price (as defined in 
    Section 14.5(f)) on the Record Date fixed for determination of 
    stockholders entitled to receive such rights, options or warrants, the 
    Conversion Price shall be adjusted so that the same shall equal the 
    price determined by multiplying the Conversion Price in effect at the 
    opening of business on the date after the Record Date by a fraction the 
    numerator of which shall be the number of shares of Common Stock 
    outstanding at the close of business on the Record Date plus the number 
    of shares that the aggregate offering price of the total number of 
    shares so offered would purchase at such Current Market Price, and the 
    denominator of which shall be the number of shares of Common Stock 
    outstanding on the close of business on the Record Date plus the total 
    number of additional shares of Common Stock so offered for subscription 
    or purchase.  Such adjustment shall become effective immediately after 
    the opening of business on the day following the Record Date fixed for 
    determination of stockholders entitled to receive such rights, options 
    or warrants.  To the extent that shares of Common Stock are not 
    delivered after the expiration or termination of such rights, options or 
    warrants, the Conversion Price shall 

                                      73
<PAGE>

    be readjusted to the Conversion Price that would then be in effect had the 
    adjustments made upon the issuance of such rights, options or warrants been
    made on the basis of delivery of only the number of shares of Common Stock 
    actually delivered.  In the event that such rights, options or warrants are
    not so issued, the Conversion Price shall again be adjusted to be the 
    Conversion Price that would then be in effect if such date fixed for the 
    determination of stockholders entitled to receive such rights, options 
    or warrants had not been fixed.  In determining whether any rights, 
    options or warrants entitle the holders to subscribe for or purchase 
    shares of Common Stock at less than such Current Market Price, and in 
    determining the aggregate offering price of such shares of Common Stock, 
    there shall be taken into account any consideration received for such 
    rights, options or warrants, the value of such consideration, if other 
    than cash, to be determined by the Board of Directors.
    
         (c)  In case the Company shall, by dividend or otherwise, 
    distribute to all holders of its Common Stock shares of any class of 
    capital stock of the Company (other than any dividends or distributions 
    to which Section 14.5(a) applies) or evidences of its indebtedness or 
    assets (including securities, but excluding any rights, options or 
    warrants referred to in Section 14.5(b), and excluding any dividend or 
    distribution (x) in connection with the liquidation, dissolution or 
    winding-up of the Company, whether voluntary or involuntary, (y) 
    exclusively in cash or (z) referred to in Section 14.5(a) (any of the 
    foregoing hereinafter in this Section 14.5(c) called the "Securities")), 
    then, in each such case, the Conversion Price shall be reduced so that 
    the same shall be equal to the price determined by multiplying the 
    Conversion Price in effect immediately prior to the close of business on 
    the Record Date (as defined in Section 14.5(f)) with respect to such 
    distribution by a fraction of which the numerator shall be the Current 
    Market Price (determined as provided in Section 14.5(f)) on such date 
    less the fair market value (as determined by the Board of Directors, 
    whose determination shall be conclusive and described in a Board 
    Resolution) on such date of the portion of the Securities so distributed 
    applicable to one share of Common Stock and the denominator shall be 
    such Current Market Price, such reduction to become effective 
    immediately prior to the opening of business on the day following the 
    Record Date; provided that in the event the then fair market value (as 
    so determined) of the portion of the Securities so distributed 
    applicable to one share of Common Stock is equal to or greater than the 
    Current Market Price on the Record Date, in lieu of the foregoing 
    adjustment, adequate provision shall be made so that each Holder shall 
    have the right to receive upon conversion the amount of Securities such 
    holder would have received had such holder converted each Note on such 
    date.  In the event that such dividend or distribution is not so paid or 
    made, the Conversion Price shall again be adjusted to be the Conversion 
    Price that would then be in effect if such dividend or distribution had 
    not been declared.  If the Board of Directors 

                                      74
<PAGE>

    determines the fair market value of any distribution for purposes of this 
    Section 14.5(c) by reference to the actual or when issued trading market 
    for any securities comprising all or part of such distribution, it must in 
    doing so consider the prices in such market over the same period used in 
    computing the Current Market Price pursuant to Section 14.5(f) to the 
    extent possible.
    
         Notwithstanding the foregoing provisions of this Section 14.5(c), 
    no adjustment shall be made hereunder for any distribution of Securities 
    if the Company makes proper provision so that each Holder who converts a 
    Note (or any portion thereof) after the date fixed for determination of 
    stockholders entitled to receive such distribution shall be entitled to 
    receive upon such conversion, in addition to the shares of Common Stock 
    issuable upon such conversion, the amount and kind of Securities that 
    such holder would have been entitled to receive if such holder had, 
    immediately prior to such determination date, converted such Note into 
    Common Stock; provided that, with respect to any Securities that are 
    convertible, exchangeable or exercisable, the foregoing provision shall 
    only apply to the extent (and so long as) the Securities receivable upon 
    conversion of such Note would be convertible, exchangeable or 
    exercisable, as applicable, without any loss of rights or privileges for 
    a period of at least 60 days following conversion of such Note.
    
         Rights, options or warrants distributed by the Company to all 
    holders of Common Stock entitling the holders thereof to subscribe for 
    or purchase shares of the Company's capital stock (either initially or 
    under certain circumstances), which rights, options or warrants, until 
    the occurrence of a specified event or events (the "Trigger Event") (i) 
    are deemed to be transferred with such shares of Common Stock, (ii) are 
    not exercisable and (iii) are also issued in respect of future issuances 
    of Common Stock, shall not be deemed distributed for purposes of this 
    Section 14.5(c) (and no adjustment to the Conversion Price under Section 
    14.5(c) shall be required) until the occurrence of the earliest Trigger 
    Event.  In addition, in the event of any distribution of rights, options 
    or warrants, or any Trigger Event with respect thereto, that shall have 
    resulted in an adjustment to the Conversion Price under this Section 
    14.5(c), (1) in the case of any such rights, options or warrants that 
    shall all have been redeemed or repurchased without exercise by any 
    holders thereof, the Conversion Price shall be readjusted upon such 
    final redemption or repurchase to give effect to such distribution or 
    Trigger Event, as the case may be, as though it were a cash 
    distribution, equal to the per share redemption or repurchase price 
    received by a holder of Common Stock with respect to such rights, 
    options or warrants (assuming such holder had retained such rights, 
    options or warrants), made to all holders of Common Stock as of the date 
    of such redemption or repurchase, and (2) in the case of such rights, 
    options or warrants all of which shall have expired or 

                                      75
<PAGE>

    been terminated without exercise by any holder thereof, the Conversion 
    Price shall be readjusted as if such issuance had not occurred.
    
         For purposes of this Section 14.5(c) and Sections 14.5(a) and (b), 
    any dividend or distribution to which this Section 14.5(c) is applicable 
    that also includes shares of Common Stock, or rights, options or 
    warrants to subscribe for or purchase shares of Common Stock (or both), 
    shall be deemed instead to be (1) a dividend or distribution of the 
    evidences of indebtedness, assets or shares of capital stock other than 
    such shares of Common Stock or rights, options or warrants (and any 
    Conversion Price reduction required by this Section 14.5(c) with respect 
    to such dividend or distribution shall then be made) immediately 
    followed by (2) a dividend or distribution of such shares of Common 
    Stock or such rights, options or warrants (and any further Conversion 
    Price reduction required by Sections 14.5(a) and (b) with respect to 
    such dividend or distribution shall then be made) except (A) the Record 
    Date of such dividend or distribution shall be substituted as "the 
    record date fixed for determination of stockholders entitled to receive 
    such dividend or distribution" and "the record date fixed for 
    determination" within the meaning of Sections 14.5(a) and (b) and (B) 
    any shares of Common Stock included in such dividend or distribution 
    shall not be deemed outstanding shares of Common Stock within the 
    meaning of the last sentence of Section 14.5(a).
    
         (d)  In case the Company shall, by dividend or otherwise, 
    distribute to all holders of its Common Stock cash (excluding any cash 
    that is distributed upon a merger or consolidation to which Section 14.6 
    applies or as part of a distribution referred to in Section 14.5(c) for 
    which an adjustment to the Conversion Price is provided therein) in an 
    aggregate amount that, combined together with (1) the aggregate amount 
    of any other such distributions to all holders of its Common Stock made 
    exclusively in cash within the 12 months preceding the date of payment 
    of such distribution, and in respect of which no adjustment pursuant to 
    this Section 14.5(d) has been made, and (2) the aggregate of any cash 
    plus the fair market value (as determined by the Board of Directors, 
    whose determination shall be conclusive and described in a Board 
    Resolution) of consideration payable in respect of any tender offer, by 
    the Company or any of its subsidiaries for all or any portion of the 
    Common Stock concluded within the 12 months preceding the date of 
    payment of such distribution, and in respect of which no adjustment 
    pursuant to Section 14.5(e) has been made, exceeds 20.0% of the product 
    of the Current Market Price (determined as provided in Section 14.5(f)) 
    on the Record Date with respect to such distribution times the number of 
    shares of Common Stock outstanding on such Record Date, then, and in 
    each such case, immediately after the close of business on such Record 
    Date, unless the Company elects to reserve such cash for distribution to 
    the holders of the Notes upon the conversion of the Notes so that any 
    such holder converting Notes shall 

                                      76
<PAGE>

    receive upon such conversion, in addition to the shares of Common Stock 
    to which such holder is entitled, the amount of cash which such holder 
    would have received if such holder had, immediately prior to the Record 
    Date for such distribution of cash, converted its Notes into Common 
    Stock, the Conversion Price shall be reduced so that the same shall 
    equal the price determined by multiplying the Conversion Price in effect 
    immediately prior to the close of business on such Record Date by a 
    fraction (i) the numerator of which shall be equal to the Current Market 
    Price on the Record Date less an amount equal to the quotient of (x) the 
    excess of such combined amount over such 20.0% and (y) the number of 
    shares of Common Stock outstanding on the Record Date and (ii) the 
    denominator of which shall be equal to the Current Market Price on such 
    date; provided that in the event the portion of the cash so distributed 
    applicable to one share of Common Stock is equal to or greater than the 
    Current Market Price of the Common Stock on the Record Date, in lieu of 
    the foregoing adjustment, adequate provision shall be made so that each 
    Holder shall have the right to receive upon conversion the amount of 
    cash such holder would have received had such holder converted each Note 
    on the Record Date.  In the event that such dividend or distribution is 
    not so paid or made, the Conversion Price shall again be adjusted to be 
    the Conversion Price that would then be in effect if such dividend or 
    distribution had not been declared.
    
         (e)  In case a tender offer made by the Company or any of its 
    subsidiaries for all or any portion of the Common Stock shall expire and 
    such tender offer (as amended upon the expiration thereof) shall require 
    the payment to stockholders (based on the acceptance (up to any maximum 
    specified in the terms of the tender offer) of Purchased Shares (as 
    defined below)) of an aggregate consideration having a fair market value 
    (as determined by the Board of Directors, whose determination shall be 
    conclusive and described in a Board Resolution) that combined together 
    with (1) the aggregate of the cash plus the fair market value (as 
    determined by the Board of Directors, whose determination shall be 
    conclusive and described in a Board Resolution), as of the expiration of 
    such tender offer, of consideration payable in respect of any other 
    tender offer, by the Company or any of its subsidiaries for all or any 
    portion of the Common Stock expiring within the 12 months preceding the 
    expiration of such tender offer, and in respect of which no adjustment 
    pursuant to Section 14.5(e) has been made, and (2) the aggregate amount 
    of any distributions to all holders of the Company's Common Stock made 
    exclusively in cash within 12 months preceding the expiration of such 
    tender offer, and in respect of which no adjustment pursuant to Section 
    14.5 (d) has been made, exceeds 20.0% of the product of the Current 
    Market Price (determined as provided in Section 14.5(f)) as of the last 
    time (the "Expiration Time") tenders could have been made pursuant to 
    such tender offer (as it may be amended) times the number of shares of 
    Common Stock outstanding (including any tendered shares) on the 
    Expiration Time, 

                                      77
<PAGE>

    then, and in each such case, immediately prior to the opening of business 
    on the day after the date of the Expiration Time, the Conversion Price 
    shall be adjusted so that the same shall equal the price determined by 
    multiplying the Conversion Price in effect immediately prior to close of 
    business on the date of the Expiration Time by a fraction of which the 
    numerator shall be the number of shares of Common Stock outstanding 
    (including any tendered shares) on the Expiration Time multiplied by the 
    Current Market Price of the Common Stock on the Trading Day next succeeding
    the Expiration Time and the denominator shall be the sum of (x) the fair 
    market value (determined as aforesaid) of the aggregate consideration 
    payable to stockholders based on the acceptance (up to any maximum 
    specified in the terms of the tender offer) of all shares validly tendered 
    and not withdrawn as of the Expiration Time (the shares deemed so accepted,
    up to any such maximum, being referred to as the "Purchased Shares") and 
    (y) the product of the number of shares of Common Stock outstanding (less 
    any Purchased Shares) on the Expiration Time and the Current Market Price 
    of the Common Stock on the Trading Day next succeeding the Expiration Time,
    such reduction to become effective immediately prior to the opening of 
    business on the day following the Expiration Time.  In the event that the 
    Company is obligated to purchase shares pursuant to any such tender offer, 
    but the Company is permanently prevented by applicable law from effecting 
    any such purchases or all such purchases are rescinded, the Conversion 
    Price shall again be adjusted to be the Conversion Price that would then 
    be in effect if such tender offer had not been made.

         (f)  For purposes of this Section 14.5, the following terms shall 
    have the meaning indicated:

              (1)  "Closing Price" with respect to any securities on any day
         shall mean the closing sale price regular way on such day or, in case
         no such sale takes place on such day, the average of the reported
         closing bid and asked prices, regular way, in each case on the New
         York Stock Exchange, or, if such security is not listed or admitted to
         trading on such Exchange, on the principal national security exchange
         or quotation system on which such security is quoted or listed or
         admitted to trading, or, if not quoted or listed or admitted to
         trading on any national securities exchange or quotation system, the
         average of the closing bid and asked prices of such security on the
         over-the-counter market on the day in question as reported by the
         National Quotation Bureau Incorporated, or a similar generally
         accepted reporting service, or if not so available, in such manner as
         furnished by any New York Stock Exchange member firm selected from
         time to time by the Board of Directors for that purpose, or a price
         determined in good faith by the Board of Directors, whose
         determination shall be conclusive and described in a Board Resolution.

                                      78
<PAGE>

              (2)  "Current Market Price" shall mean the average of the daily
         Closing Prices per share of Common Stock for the ten consecutive
         Trading Days immediately prior to the date in question; provided that
         (1) if the "ex" date (as hereinafter defined) for any event (other
         than the issuance or distribution or Change of Control requiring such
         computation) that requires an adjustment to the Conversion Price
         pursuant to Section 14.5(a), (b), (c), (d) or (e) occurs during such
         ten consecutive Trading Days, the Closing Price for each Trading Day
         prior to the "ex" date for such other event shall be adjusted by
         multiplying such Closing Price by the same fraction by which the
         Conversion Price is so required to be adjusted as a result of such
         other event, (2) if the "ex" date for any event (other than the
         issuance, distribution or Change of Control requiring such
         computation) that requires an adjustment to the Conversion Price
         pursuant to Section 14.5(a), (b), (c), (d) or (e) occurs on or after
         the "ex" date for the issuance or distribution requiring such
         computation and prior to the day in question, the Closing Price for
         each Trading Day on and after the "ex" date for such other event shall
         be adjusted by multiplying such Closing Price by the reciprocal of the
         fraction by which the Conversion Price is so required to be adjusted
         as a result of such other event and (3) if the "ex" date for the
         issuance, distribution or Change of Control requiring such computation
         is prior to the day in question, after taking into account any
         adjustment required pursuant to clause (1) or (2) of this proviso, the
         Closing Price for each Trading Day on or after such "ex" date shall be
         adjusted by adding thereto the amount of any cash and the fair market
         value (as determined by the Board of Directors in a manner consistent
         with any determination of such value for purposes of Section 14.5(d)
         or (e), whose determination shall be conclusive and described in a
         Board Resolution) of the evidences of indebtedness, shares of capital
         stock or assets being distributed applicable to one share of Common
         Stock as of the close of business on the day before such "ex" date. 
         For purposes of any computation under Section 14.5(e), the Current
         Market Price of the Common Stock on any date shall be deemed to be the
         average of the daily Closing Prices per share of Common Stock for such
         day and the next two succeeding Trading Days; provided that if the
         "ex" date for any event (other than the tender or exchange offer
         requiring such computation) that requires an adjustment to the
         Conversion Price pursuant to Section 14.5(a), (b), (c), (d) or (e)
         occurs on or after the Expiration Time for the tender or exchange
         offer requiring such computation and prior to the day in question, the
         Closing Price for each Trading Day on and after the "ex" date for such
         other event shall be adjusted by multiplying such Closing Price by the
         reciprocal of the fraction by which the Conversion Price is so
         required to be adjusted as a result of such other event.  For purposes
         of this 

                                      79
<PAGE>

         paragraph, the term "ex" date, (1) when used with respect to any 
         issuance or distribution, means the first date on which the Common
         Stock trades regular way on the relevant exchange or in the relevant
         market from which the Closing Price was obtained without the right to
         receive such issuance or distribution, (2) when used with respect to
         any subdivision or combination of shares of Common Stock, means the
         first date on which the Common Stock trades regular way on such
         exchange or in such market after the time at which such subdivision or
         combination becomes effective and (3) when used with respect to any
         tender or exchange offer means the first date on which the Common
         Stock trades regular way on such exchange or in such market after the
         expiration of such offer.  Notwithstanding the foregoing, whenever
         successive adjustments to the Conversion Price are called for pursuant
         to this Section 14.5, such adjustments shall be made to the Current
         Market Price as may be necessary or appropriate to effectuate the
         intent of this Section 14.5 and to avoid unjust or inequitable results
         as determined in good faith by the Board of Directors.

              (3)  "fair market value" shall mean the amount that a willing
         buyer would pay a willing seller in an arm's-length transaction.

              (4)  "Record Date" shall mean, with respect to any dividend,
         distribution or other transaction or event in which the holders of
         Common Stock have the right to receive any cash, securities or other
         property or in which the Common Stock (or other applicable security)
         is exchanged for or converted into any combination of cash, securities
         or other property, the date fixed for determination of stockholders
         entitled to receive such cash, securities or other property (whether
         such date is fixed by the Board of Directors or by statute, contract
         or otherwise).

              (5)  "Trading Day" shall mean (x) if the applicable security is
         listed or admitted for trading on the New York Stock Exchange or
         another national security exchange, a day on which the New York Stock
         Exchange or such other national security exchange is open for business
         or (y) if the applicable security is quoted on the Nasdaq National
         Market, a day on which trades may be made thereon or (z) if the
         applicable security is not so listed, admitted for trading or quoted,
         any day other than a Saturday or Sunday or a day on which banking
         institutions in the State of New York are authorized or obligated by
         law or executive order to close.

                                      80
<PAGE>

         (g)  The Company may make such reductions in the Conversion Price, 
    in addition to those required by Sections 14.5(a), (b), (c), (d) and 
    (e), as the Board of Directors considers to be advisable to avoid or 
    diminish any income tax to holders of Common Stock or rights to purchase 
    Common Stock resulting from any dividend or distribution of stock (or 
    rights to acquire stock) or from any event treated as such for income 
    tax purposes.  To the extent permitted by applicable law, the Company 
    from time to time may reduce the Conversion Price by any amount for any 
    period of time if the period is at least 20 days, the reduction is 
    irrevocable during the period and the Board of Directors shall have made 
    a determination that such reduction would be in the best interests of 
    the Company, which determination shall be conclusive and described in a 
    Board Resolution. Whenever the Conversion Price is reduced pursuant to 
    the preceding sentence, the Company shall mail to all holders of record 
    of the Notes a notice of the reduction at least 15 days prior to the 
    date the reduced Conversion Price takes effect, and such notice shall 
    state the reduced Conversion Price and the period it shall be in effect.
    
         (h)  No adjustment in the Conversion Price shall be required unless 
    such adjustment would require an increase or decrease of at least 1% in 
    such price; provided that any adjustments that by reason of this Section 
    14.5(h) are not required to be made shall be carried forward and taken 
    into account in any subsequent adjustment.  All calculations under this 
    Article XIV shall be made by the Company and shall be made to the 
    nearest 1/100 (with 0.005 being rolled upward).
    
         No adjustment need be made for rights to purchase Common Stock 
    pursuant to a Company plan for reinvestment of dividends or interest.
    
         No adjustment need be made for a change in the par value, or to or 
    from no par value, of the Common Stock.
    
         To the extent the Notes become convertible into cash, assets, 
    property or securities (other than Common Stock of the Company), no 
    adjustment need be made thereafter as to the cash, assets, property or 
    such securities (except as such securities may otherwise by their terms 
    provide), and interest shall not accrue on such cash.
    
         (i)  Whenever the Conversion Price is adjusted as herein provided, 
    the Company shall promptly file with the Trustee and any conversion 
    agent other than the Trustee an Officers' Certificate setting forth the 
    Conversion Price after such adjustment and setting forth a brief 
    statement of the facts requiring such adjustment.  Promptly after 
    delivery of such certificate, the Company shall prepare a notice of such 
    adjustment of the Conversion Price setting forth the adjusted Conversion 
    Price and the date on which each 

                                      81
<PAGE>

    adjustment becomes effective and shall mail such notice of such adjustment 
    of the Conversion Price to the holder of each Note at his last address 
    appearing on the Note register provided for in Section 2.5, within 20 days 
    after execution thereof.  Failure to deliver such notice shall not effect 
    the legality or validity of any such adjustment.
    
         (j)  In any case in which this Section 14.5 provides that an 
    adjustment shall become effective immediately after a Record Date for an 
    event, the Company may defer until the occurrence of such event (i) 
    issuing to the holder of any Note converted after such Record Date and 
    before the occurrence of such event the additional shares of Common 
    Stock issuable upon such conversion by reason of the adjustment required 
    by such event over and above the Common Stock issuable upon such 
    conversion before giving effect to such adjustment and (ii) paying to 
    such holder any amount in cash in lieu of any fraction pursuant to 
    Section 14.3.

    14.6 EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE.  If any 
of the following events occur, namely (i) any reclassification or change of 
outstanding shares of Common Stock (other than a change in par value, or to 
or from no par value, as a result of a subdivision or combination), (ii) any 
consolidation, merger or combination of the Company with another corporation 
as a result of which holders of Common Stock shall be entitled to receive 
stock, securities or other property or assets (including cash) with respect 
to or in exchange for such Common Stock or (iii) any sale or conveyance of 
the properties and assets of the Company as, or substantially as, an entirety 
(determined on a consolidated basis) to any other corporation as a result of 
which holders of Common Stock shall be entitled to receive stock, securities 
or other property or assets (including cash) with respect to or in exchange 
for such Common Stock, then the Company or the successor or purchasing 
corporation, as the case may be, shall execute with the Trustee a 
supplemental indenture (which shall comply with the Trust Indenture Act as in 
force at the date of execution of such supplemental indenture if such 
supplemental indenture is then required to so comply) providing that the 
Notes shall be convertible into the kind and amount of shares of stock and 
other securities or property or assets (including cash) receivable upon such 
reclassification, change, consolidation, merger, combination, sale or 
conveyance by a holder of a number of shares of Common Stock issuable upon 
conversion of such Notes (assuming, for such purposes, a sufficient number of 
authorized shares of Common Stock available to convert all such Notes) 
immediately prior to such reclassification, change, consolidation, merger, 
combination, sale or conveyance, assuming such holder of Common Stock did not 
exercise his rights of election, if any, as to the kind or amount of 
securities, cash or other property receivable upon such reclassification, 
change, consolidation, merger, combination, sale or conveyance (provided 
that, if the kind or amount of securities, cash or other property receivable 
upon such reclassification, change, consolidation, merger, combination, sale 
or conveyance is not the same for each share of Common Stock in respect of 
which such rights

                                      82
<PAGE>

of election shall not have been exercised ("non-electing share"), then for 
the purposes of this Section 14.6 the kind and amount of securities, cash or 
other property receivable upon such reclassification, change, consolidation, 
merger, combination, sale or conveyance for each non-electing share shall be 
deemed to be the kind and amount so receivable per share by a plurality of 
the non-electing shares).  Such supplemental indenture shall provide for 
adjustments that shall be as nearly equivalent as may be practicable to the 
adjustments provided for in this Article XIV.

    The Company shall cause notice of the execution of such supplemental 
indenture to be mailed to each holder of Notes, at his address appearing on 
the Note register provided for in Section 2.5, within 20 days after execution 
thereof.  Failure to deliver such notice shall not affect the legality or 
validity of such supplemental indenture.

    The above provisions of this Section 14.6 shall similarly apply to 
successive reclassifications, changes, consolidations, mergers, combinations, 
sales and conveyances.

    14.7 TAXES ON SHARES ISSUED.  The issuance of stock certificates on 
conversions of Notes shall be made without charge to the converting Holder 
for any transfer or similar tax in respect of the issue thereof.  The Company 
shall not, however, be required to pay any tax that may be payable in respect 
of any transfer involved in the issue and delivery of stock in any name other 
than that of the holder of any Note converted, and the Company shall not be 
required to issue or deliver any such stock certificate unless and until the 
person or persons requesting the issuance thereof shall have paid to the 
Company the amount of such tax or shall have established to the satisfaction 
of the Company that such tax has been paid.

    14.8 RESERVATION OF SHARES; SHARES TO BE FULLY PAID; LISTING OF COMMON 
STOCK.  The Company shall provide, free from preemptive rights, out of its 
authorized but unissued shares or shares held in treasury, sufficient shares 
to provide for the conversion of the Notes from time to time as such Notes 
are presented for conversion.

    Before taking any action that would cause an adjustment reducing the 
Conversion Price below the then par value, if any, of the shares of Common 
Stock issuable upon conversion of the Notes, the Company shall take all 
corporate action that may, in the opinion of its counsel, be necessary in 
order that the Company may validly and legally issue shares of such Common 
Stock at such adjusted Conversion Price.

    The Company covenants that all shares of Common Stock that may be issued 
upon conversion of Notes shall, upon issuance, be fully paid and 
nonassessable by the Company and free from all taxes, liens and charges with 
respect to the issuance thereof.

                                      83
<PAGE>

    The Company further covenants that it shall, if permitted by the rules of 
each securities exchange upon which the Common Stock is listed, list and keep 
listed, so long as the Common Stock shall be so listed on such exchanges, all 
Common Stock issuable upon conversion of the Notes.

    14.9 RESPONSIBILITY OF TRUSTEE.  The Trustee and any other conversion 
agent shall not at any time be under any duty or responsibility to any holder 
of Notes to determine whether any facts exist that may require any adjustment 
of the Conversion Price, or with respect to the nature or extent or 
calculation of any such adjustment when made, or with respect to the method 
employed, or herein or in any supplemental indenture provided to be employed, 
in making the same.  The Trustee and any other conversion agent shall not be 
accountable with respect to the validity or value (or the kind or amount) of 
any shares of Common Stock, or of any securities or property, that may at any 
time be issued or delivered upon the conversion of any Note; and the Trustee 
and any other conversion agent make no representations with respect thereto.  
Subject to the provisions of Section 7.1, neither the Trustee nor any 
conversion agent shall be responsible for any failure of the Company to 
issue, transfer or deliver any shares of Common Stock or stock certificates 
or other securities or property or cash upon the surrender of any debenture 
for the purpose of conversion or to comply with any of the duties, 
responsibilities or covenants of the Company contained in this Article XIV.  
Without limiting the generality of the foregoing, neither the Trustee nor any 
conversion agent shall be under any responsibility to determine whether a 
supplemental indenture under Section 14.6 hereof need to be entered into or 
the correctness of any provisions contained in any supplemental indenture 
entered into pursuant to Section 14.6 relating either to the kind or amount 
of shares of stock or securities or property (including cash) receivable by 
Holders upon the conversion of their Notes after any event referred to in 
such Section 14.6 or to any adjustment to be made with respect thereto, but, 
subject to the provisions of Section 7.1, may accept as conclusive evidence 
of the correctness of any such provisions, and shall be protected in relying 
upon, the Officers' Certificate (which the Company shall be obligated to file 
with the Trustee prior to the execution of any such supplemental indenture) 
with respect thereto.

    14.10     NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS.  In case:

         (a)  the Company makes any distribution or dividend that would require
    an adjustment in the Conversion Price pursuant to Section 14.5; or

         (b)  the Company takes any action that would require a supplemental
    indenture pursuant to Section 14.6; or

                                      84
<PAGE>

         (c)  of the voluntary or involuntary dissolution, liquidation or
    winding-up of the Company,

the Company shall cause to be filed with the Trustee and to be mailed to each 
holder of Notes at his address appearing on the Note register, as promptly as 
possible but in any event at least 15 days prior to the applicable date 
hereinafter specified, a notice stating (x) the date on which a record date 
is to be taken for the purpose of such dividend, distribution, rights, 
options or warrants, or, if a record is not to be taken, the date as of which 
the holders of Common Stock of record to be entitled to such dividend, 
distribution, rights, options or warrants are to be determined or (y) the 
date on which such reclassification, change, consolidation, merger, sale, 
conveyance, transfer, dissolution, liquidation or winding-up is expected to 
become effective or occur and the date as of which it is expected that 
holders of record of Common Stock shall be entitled to exchange their Common 
Stock for securities or other property deliverable upon such 
reclassification, change, consolidation, merger, sale, conveyance, transfer, 
dissolution, liquidation or winding-up.  Neither the failure to give such 
notice nor any defect therein shall affect the legality or validity of the 
proceedings referenced in clauses (a) through (c) of this Section 14.10.

                                      XV

    15.1 AGREEMENT TO SUBORDINATE.  The Company agrees, and each Holder by 
accepting a Note agrees, that the indebtedness evidenced by the Notes is 
subordinated in right of payment, to the extent and in the manner provided in

that the subordination is for the benefit of the holders of Senior 
Indebtedness.

    at all times constitute the holders of a majority in outstanding principal

    outstanding on the date hereof or hereafter incurred, assumed, arising,

    whether or not contingent, of the Company for money borrowed evidenced by
    notes or other written obligations, (b) any foreign exchange contract,

    which any such indebtedness described in clauses (a) through (g) is
    created, issued, assumed or guaranteed expressly provides that such
    indebtedness is not senior or superior in right of payment to the Notes;
    PROVIDED, 

                                      86
<PAGE>

    HOWEVER, that the following shall not constitute Senior Indebtedness:  
    (i) any indebtedness or obligation of the Company in respect of the Notes, 
    (ii) any indebtedness of the Company to any of its subsidiaries or other 
    Affiliates; (iii) any indebtedness that is subordinated or junior in any 
    respect to any other indebtedness of the Company other than indebtedness 
    described in clauses (a) through (g) above; and (iv) any indebtedness 
    incurred for the purchase of goods or materials in the ordinary course of 
    business.

    For the purposes of this Indenture, Senior Indebtedness shall not be 
deemed to have been paid in full until the holders of the Senior Indebtedness 
shall have indefeasibly received payment in full in cash or cash equivalents 
of all Senior Indebtedness; provided that if any holder of Senior 
Indebtedness agrees to accept payment in full of such Senior Indebtedness for 
consideration other than cash, such holder shall be deemed to have 
indefeasibly received payment in full of such Senior Indebtedness.  The 
provisions of this Article XV shall continue to be effective or be 
reinstated, as the case may be, if at any time any payment of any of the 
Senior Indebtedness is rescinded or must otherwise be returned by any holder 
of Senior Indebtedness upon the insolvency, bankruptcy or organization of the 
Company or otherwise, all as though such payment had not been made.

    A distribution may consist of cash, cash equivalents, securities or other 
property, by set-off or otherwise.

    15.3 LIQUIDATION; DISSOLUTION; BANKRUPTCY.  Upon any distribution to 
creditors of the Company in a liquidation or dissolution of the Company or in 
a bankruptcy, reorganization, insolvency, receivership or similar proceeding 
related to the Company or its property, in an assignment for the benefit of 
creditors or any marshalling of the Company's assets and liabilities, (a) 
holders of Senior Indebtedness shall first be entitled to receive payment in 
full, in cash or cash equivalents, of all amounts due or to become due 
thereon before Holders shall be entitled to receive any payment or 
distribution of any kind or character, whether in cash, cash equivalent, 
property or securities, on or in respect of the Obligations, or for the 
acquisition of any of the Notes for cash, cash equivalents, property or 
securities; and (b) until all Senior Indebtedness (as provided in clause (a) 
above) is paid in full, in cash or cash equivalents, any payment or 
distribution to which Holders would be entitled but for this Article shall be 
made to holders of Senior Indebtedness, as their interests may appear.

    15.4 DEFAULT ON SENIOR INDEBTEDNESS.  The Company may not make any 
payment upon or in respect of the Notes and may not acquire from the Trustee 
or any Holder any Note for cash, cash equivalents, property, securities or 
otherwise until all Senior Indebtedness has been paid in full, in cash or 
cash equivalents, if:

                                      87
<PAGE>

         (a)  a Payment Default with respect to any Senior Indebtedness
    occurs and is continuing beyond any applicable period of grace; or 

         (b)  a default occurs and is continuing with respect to any
    Senior Indebtedness resulting in the acceleration of maturity of all
    or any portion of such Senior Indebtedness.  No payment on any of the
    Obligations shall be made if, and the Company shall not acquire any
    Notes while, any other default (a "nonpayment default") occurs and is
    continuing (or would occur upon any payment or distribution with
    respect to the Obligations) with respect to Senior Indebtedness that
    permits holders of the Senior Indebtedness as to which such default
    relates to accelerate its maturity and the Trustee receives a notice
    of such default (a "Payment Blockage Notice") from the Bank
    Representative or Representative or Representatives of holders of at
    least a majority in principal amount of Senior Indebtedness then
    outstanding.

    The Company may and shall resume payments on and distributions in respect 
of the Notes and may acquire them upon the earlier of:

         (a)  in the case of a Payment Default, upon the date on which the 
    default is cured or waived, or

         (b)  in the case of a nonpayment default, 179 days after the date on
    which the applicable Payment Blockage Notice is received (or sooner, if
    such default is cured or waived), unless the maturity of such Senior
    Indebtedness has been accelerated.  No new period of payment blockage may
    be commenced by a creditor within 360 days after the receipt by the Trustee
    of any prior Payment Blockage Notice by or on behalf of such creditor.  No
    non-payment default that existed or was continuing on the date of delivery
    of any Payment Blockage Notice to the Trustee shall be, or be made, the
    basis for a subsequent Payment Blockage Notice, unless such non-payment
    default shall have been cured or waived for a period of not less than 90
    consecutive days,

if this Article XV otherwise permits the payment, distribution or acquisition 
at the time of such payment or acquisition.

    15.5 WHEN DISTRIBUTION MUST BE PAID OVER.  In the event that the Trustee 
(or paying agent if other than the Trustee) or any Holder receives any 
payment of principal or interest with respect to the Obligations at a time 
when such payment is prohibited by Section 15.3 or 15.4 hereof, 

                                      88
<PAGE>

such payment shall be held by the Trustee (or paying agent if other than the 
Trustee) or such Holder, in trust for the benefit of, and immediately shall 
be paid over and delivered, upon written request, to, the holders of Senior 
Indebtedness as their interests may appear or their Representative under the 
indenture or other agreement (if any) pursuant to which Senior Indebtedness 
may have been issued, as their respective interests may appear, for 
application to the payment of all Senior Indebtedness remaining unpaid to the 
extent necessary to pay all Senior Indebtedness in full, in cash or cash 
equivalents, in accordance with its terms, after giving effect to any 
concurrent payment or distribution to or for the holders of Senior 
Indebtedness.

    With respect to the holders of Senior Indebtedness, the Trustee 
undertakes to perform only such obligations on the part of the Trustee as are 
specifically set forth in this Article XV, and no implied covenants or 
obligations with respect to the holders of Senior Indebtedness shall be read 
into this Indenture against the Trustee.  The Trustee shall not be deemed to 
owe any fiduciary duty to the holders of Senior Indebtedness and shall not be 
liable to any such holders if the Trustee shall pay over or distribute to or 
on behalf of Holders or the Company or any other person money or assets to 
which any holders of Senior Indebtedness shall be entitled by virtue of this 
Article XV, except if such payment is made as a result of the willful 
misconduct or gross negligence of the Trustee.

    15.6 NOTICE BY COMPANY.  The Company shall promptly notify the Trustee 
and the paying agent of any facts known to the Company that would cause a 
payment of any principal or interest with respect to the Notes to violate 
this Article XV, but failure to give such notice shall not affect the 
subordination of the Obligations to the Senior Indebtedness as provided in 
this Article XV.

    15.7 SUBROGATION.  After all Senior Indebtedness is paid in full and 
until the Notes are paid in full, Holders shall be subrogated (equally and 
ratably with all other Indebtedness pari passu with the Notes) to the rights 
of holders of Senior Indebtedness to receive distributions applicable to 
Senior Indebtedness to the extent that distributions otherwise payable to the 
Holders have been applied to the payment of Senior Indebtedness.  A 
distribution made under this Article XV to holders of Senior Indebtedness 
that otherwise would have been made to Holders is not, as between the Company 
and Holders, a payment by the Company on the Notes.

    15.8 RELATIVE RIGHTS.  This Article XV defines the relative rights of 
Holders and holders of Senior Indebtedness.  Nothing in this Indenture shall:

         (a)  impair, as between the Company and the Holders, the obligation of
    the Company, which is absolute and unconditional, to pay principal of,
    premium, if any, and interest on the Notes in accordance with their terms;

                                      89
<PAGE>

         (b)  affect the relative rights of Holders and creditors of the
    Company other than their rights in relation to holders of Senior
    Indebtedness; or

         (c)  prevent the Trustee or any Holder from exercising its available
    remedies upon a default or Event of Default, subject to the rights of
    holders and owners of Senior Indebtedness to receive distributions and
    payments otherwise payable to Holders.

    If the Company fails because of this Article XV to pay principal of, 
premium, if any, or interest on a Note on the due date, the failure is still 
a default or Event of Default. 

    15.9 SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.  No right of any 
holder of Senior Indebtedness to enforce the subordination of the Obligations 
shall be impaired by any act or failure to act by the Company or any holder 
of Notes or by the failure of the Company or any holder of Notes to comply 
with this Indenture. 

    15.10     DISTRIBUTION OR NOTICE TO REPRESENTATIVE.  Whenever a 
distribution is to be made or a notice given to holders of Senior 
Indebtedness, the distribution may be made and the notice given to their 
Representative. 

    Upon any payment or distribution of assets of the Company referred to in 
this Article XV, the Trustee and the Holders shall be entitled to rely upon 
any order or decree made by any court of competent jurisdiction or upon any 
certificate of such Representative or of the liquidating trustee or agent or 
other person making any distribution to the Trustee or to the Holders for the 
purpose of ascertaining the persons entitled to participate in such 
distribution, the holders of the Senior Indebtedness and other indebtedness 
of the Company, the amount thereof or payable thereon, the amount or amounts 
paid or distributed thereon and all other facts pertinent thereto or to this 
Article XV.

    15.11     RIGHTS OF TRUSTEE AND PAYING AGENT.  Notwithstanding the 
provisions of this Article XV or any other provision of this Indenture, the 
Trustee shall not be charged with knowledge of the existence of any facts 
that would prohibit the making of any payment or distribution by the Trustee, 
and the Trustee and the paying agent may continue to make payments on the 
Notes, unless the Trustee shall have received at its Corporate Trust Office 
at least three Business Days prior to the date of such payment written notice 
of facts that would cause the payment of any principal, premium, if any, and 
interest with respect to the Notes to violate this Article XV.  Only the 
Company or a Representative may give the notice.  Nothing in this Article XV 
shall impair the claims of, or payments to, the Trustee under or pursuant to 
Section 7.7 hereof.

                                      90
<PAGE>

    The Trustee shall be entitled to rely on the delivery to it of a written 
notice by a person representing such person to be a holder of Senior 
Indebtedness (or a trustee or agent on behalf of such holder) to establish 
that such notice has been given by a holder of Senior Indebtedness (or a 
trustee or agent on behalf of any such holder).  In the event that the 
Trustee determines in good faith that further evidence is required with 
respect to the right of any person as a holder of Senior Indebtedness to 
participate in any payment or distribution pursuant to this Article XV, the 
Trustee may request such person to furnish evidence to the reasonable 
satisfaction of the Trustee as to the amount of Senior Indebtedness held by 
such person, the extent to which such person is entitled to participate in 
such payment or distribution and any other facts pertinent to the rights of 
such person under this Article XV, and if such evidence is not furnished, the 
Trustee may defer any payment which it may be required to make for the 
benefit of such person pursuant to the terms of this Indenture pending 
judicial determination as to the rights of such person to receive such 
payment.

    The Trustee in its individual or any other capacity may hold Senior 
Indebtedness with the same rights it would have if it were not Trustee.  Any 
paying agent, any authenticating agent, any conversion agent, any Note 
registrar and their successors may do the same with like rights.

    15.12     AUTHORIZATION TO EFFECT SUBORDINATION.  Each holder of a Note 
by the holder's acceptance thereof authorizes and directs the Trustee on the 
holder's behalf to take such action as may be necessary or appropriate to 
effectuate the subordination as provided in this Article XV and appoints the 
Trustee to act as the holder's attorney-in-fact for any and all such 
purposes. Without limiting the foregoing, each Representative is hereby 
irrevocably authorized and empowered (in its own name or in the name of the 
Holders or the Trustee or otherwise), but shall have no obligation, to 
demand, sue for, collect and receive every payment or distribution referred 
to in Section 15.3 above and give acquittance therefor and to file claims and 
proofs of claim and take such other action as it may deem necessary or 
advisable for the exercise or enforcement of any of the rights or interests 
of the holders or owners of the Senior Indebtedness hereunder; provided that 
for purposes of this Section 15.12 holders or owners of Senior Indebtedness 
may act only through such Representative.

    15.13     CONVERSIONS NOT DEEMED PAYMENT.  For the purposes of this 
Article XV only, the issuance and delivery of Common Stock upon conversion of 
the Notes in accordance with Article XIV shall not be deemed to constitute a 
payment or distribution on account of the principal of or interest on the 
Notes or on account of the purchase or other acquisition of Notes.  Nothing 
contained in this Article or elsewhere in this Indenture or in the Notes is 
intended to or shall impair, as among the Company, its creditors other than 
holders of Senior Indebtedness and the holders, the right, which is absolute 
and unconditional, of the holder of any Note to convert such Note in 
accordance with Article XIV.

                                      91

    15.14     AMENDMENTS.  The provisions of this Article XV shall not be 
amended or modified without the written consent of the holders of Senior 
Indebtedness.

                                     XVI
                           MISCELLANEOUS PROVISIONS

    16.1 POOLING OF INTERESTS.  The Company desires to preserve its ability

the pooling-of-interests method where appropriate, and the provisions of this 
Indenture shall be interpreted accordingly.

stipulations, promises and agreements in this Indenture made by the Company

provision of this Indenture authorized or required to be done or performed by 
any board (including the Board of Directors), committee or officer of the 
Company shall and may be done and performed with like force and effect by the 
like board, committee or officer of any corporation that shall at the time be 
the lawful sole successor of the Company.

    16.4 ADDRESSES FOR NOTICES, ETC.  Any notice or demand that by any 
provision of this Indenture is required or permitted to be given or served by

been sufficiently given or made, for all purposes if given or served by being

another address is filed by the Company with the Trustee) to CellStar

different addresses for subsequent notices or communications.

                                      92
<PAGE>

    Any notice or communication mailed to a Holder shall be mailed to him by 
first class mail, postage prepaid, at the address of such Holder as it 
appears on the Note register and shall be sufficiently given to such Holder 
if so mailed within the time prescribed.

    Failure to mail a notice or communication to a Holder or any defect in it 
shall not affect its sufficiency with respect to other Holders.  If a notice 
or communication is mailed in the manner provided above, it is duly given, 
whether or not the addressee receives it.

    16.5 COMMUNICATIONS BY HOLDERS WITH OTHER HOLDERS.  Holders may 
communicate pursuant to Trust Indenture Act Section 312(b) with other Holders 
with respect to their rights under this Indenture or the Notes.  The Company, 
the Trustee, the Note registrar and any other person shall have the 
protection of Trust Indenture Act Section 312(c).

    16.6 GOVERNING LAW.  This Indenture and each Note shall be deemed to be a

examination or investigation upon which the statement or opinion contained in 
such certificate or opinion is based, (3) a statement that, in the opinion of 
such person, he has made such examination or investigation as is necessary to 
enable him to express an informed opinion as to whether or not such covenant 
or condition has been complied with and (4) a statement as to whether or not, 
in the opinion of such person, such condition or covenant has been complied 
with.

    16.8 LEGAL HOLIDAYS.  In any case where any interest payment date, date 
fixed for redemption, stated maturity or Change of Control Purchase Date of 
any Note or the last date on which a Holder has the right to convert his 
Notes shall not be a Business Day, then

<PAGE>

(notwithstanding any other provision of this Indenture or of the Notes)

interest shall accrue for the period from and after such interest payment 
date, date fixed for redemption, Change of Control Purchase Date or stated 
maturity, as the case may be.

    16.9 NO SECURITY INTEREST CREATED.  Nothing in this Indenture or in the 
Notes, expressed or implied, shall be construed to constitute a security 
interest under the Uniform Commercial Code or similar legislation, as now or 
hereafter enacted and in effect, in any jurisdiction where property of the 
Company or its subsidiaries is located.

    16.10     TRUST INDENTURE ACT.  This Indenture is hereby made subject to, 
and shall be governed by, the provisions of the Trust Indenture Act required

connection with the original issuance thereof and transfers and exchanges of

fully to all intents and purposes as though the authenticating agent had been 
expressly authorized by this Indenture and those Sections to authenticate and 
deliver Notes.  For all purposes of this Indenture, the authentication and 
delivery of Notes by the authenticating agent shall be deemed to be 

                                      94
<PAGE>

authentication and delivery of such Notes "by the Trustee" and a certificate 
of authentication executed on behalf of the Trustee by an authenticating 
agent shall be deemed to satisfy any requirement hereunder or in the Notes 
for the Trustee's certificate of authentication.  Such authenticating agent 
shall at all times be a person eligible to serve as Trustee hereunder 
pursuant to Section 7.10.

    Any corporation into which any authenticating agent may be merged or 
converted or with which it may be consolidated, or any corporation resulting 
from any merger, consolidation or conversion to which any authenticating 
agent shall be a party, or any corporation succeeding to the corporate trust 
business of any authenticating agent, shall be the successor of the 
authenticating agent hereunder, if such successor company is otherwise 
eligible under this Section, without the execution or filing of any paper or 
any further act on the part of the parties hereto or the authenticating agent 
or such successor company.

    Any authenticating agent may at any time resign by giving written notice 
of resignation to the Trustee and to the Company.  The Trustee may at any 
time terminate the agency of any authenticating agent by giving written 
notice of termination to such authenticating agent and to the Company.  Upon 
receiving such a notice of resignation or upon such a termination, or in case 
at any time any authenticating agent shall cease to be eligible under this 
Section, the Trustee shall promptly appoint a successor authenticating agent 
(which may be the Trustee), shall give written notice of such appointment to 
the Company and shall mail notice of such appointment to all holders of Notes 
as the names and addresses of such holders appear on the Note register.

    The Company agrees to pay to the authenticating agent from time to time 
reasonable compensation for its services.

    The provisions of Sections 7.3, 7.4, 7.5, 8.3 and this Section 16.14 
shall be applicable to any authenticating agent.

    16.15     EXECUTION IN COUNTERPARTS.  This Indenture may be executed in 
any number of counterparts, each of which shall be an original, but such 
counterparts shall together constitute but one and the same instrument.

2.  SHELF REGISTRATION

    (a)  The Company hereby agrees to use all reasonable efforts to:

         (i)   file with the Commission no later than the Targeted Filing Date,
    a registration statement for an offering to be made on a continuous basis
    pursuant to Rule 415 under the Securities Act (or any successor provision
    thereto) covering all of the Transfer Restricted Securities (the "SHELF
    REGISTRATION STATEMENT"); and

         (ii)  cause the Shelf Registration Statement to be declared effective
    pursuant to the Securities Act by the Effectiveness Target Date, and use
    all reasonable efforts to keep the Shelf Registration Statement
    continuously effective and available for resale of the Transfer Restricted
    Securities under the Securities Act for the period (the "EFFECTIVENESS
    PERIOD") ending on the earlier of (A) the date that is two years after the
    date on which all the Notes are issued (including those issued pursuant to
    the over-allotment option granted to the Initial Purchasers in the Purchase
    Agreement) to the Initial Purchasers, (B) the date on which there ceases to
    be outstanding any Transfer Restricted Securities, and (C) the date on
    which the Company receives an opinion from its legal counsel ("COMPANY
    COUNSEL") to the effect that all Transfer Restricted Securities can be
    freely traded without the continued effectiveness of the Shelf Registration
    Statement.


                                       5

<PAGE>

    (b)  The Company may require each Holder of Transfer Restricted Securities
as to which any registration is being effected to furnish to the Company, within
20 Business Days after written request therefor has been made by the Company,
such information regarding the distribution of such Holder's Transfer Restricted
Securities as is required by law to be disclosed in the Shelf Registration
Statement (the "REQUISITE INFORMATION"), such information to be solicited
substantially in the form of the questionnaire attached to the Offering Circular
as Annex B.

         The Company shall file prospectus supplements pursuant to Rule 424
under the Securities Act (or any successor provision thereto) to amend or
supplement the Shelf Registration Statement to include in the Shelf Registration
Statement the Requisite Information as to each Holder (and the Transfer
Restricted Securities held by such Holder) that provides notice to the Company
of the Requisite Information.  The Company shall file such a prospectus
supplement with the Commission no less than once every twenty Business Days if
during such period the Company receives notice from any Holder which includes
the Requisite Information with respect to any such Holder; provided, however,
that in the event the Company receives notice from any Holders which includes
the Requisite Information with respect to such Holders and such Requisite
Information pertains to at least $1,000,000 principal amount of Notes and/or a
comparable amount of underlying Common Stock, the Company shall file such a
prospectus supplement with the Commission within ten Business Days of the
receipt of such notice.  The Company shall provide each Holder a copy of such
Prospectus as so amended or supplemented containing the Requisite Information
within three Business Days of filing such Prospectus with the Commission in
order to permit such Holder to comply with the prospectus delivery requirements
of the Securities Act in a timely manner with respect to any proposed
disposition of such Holder's Transfer Restricted Securities.

         No Holder shall be entitled to use the Prospectus unless and until
such Holder shall have furnished the information required by this Section 2(b)
in accordance with the first or second paragraph hereof and such information
with respect to such Holder shall have been included in the Prospectus.  If any
information furnished to the Company by a Holder for inclusion in the Shelf
Registration Statement or the Prospectus becomes materially misleading, such
Holder agrees (i) to furnish promptly to the Company all information required to
be disclosed in such Shelf Registration Statement in order to make the
information previously furnished to the Company not materially misleading and
(ii) to stop selling or offering for sale Transfer Restricted Securities
pursuant to the Shelf Registration Statement until such Holder's receipt of the
copies of a supplemented or amended Prospectus as contemplated by Section
4(b)(xi) hereof.

3.  LIQUIDATED DAMAGES

    (a)  The Company and the Initial Purchasers agree that the Holders of
Transfer Restricted Securities will suffer damages if the Company fails to
fulfill its obligations pursuant to Section 2 hereof and that it would not be
possible to ascertain the extent of such damages.  Accordingly, the Company
hereby agrees to pay liquidated damages ("LIQUIDATED DAMAGES") to each Holder of
Transfer Restricted Securities under the circumstances and to the extent set
forth below:

         (i)   if the Shelf Registration Statement has not been filed with the
    Commission on or prior to the Targeted Filing Date; or

         (ii)  if the Shelf Registration Statement is not declared effective by
    the Commission on or prior to the Effectiveness Target Date; or

         (iii) if, at any time during the Effectiveness Period for a period
    of time which shall exceed 60 days in the aggregate in any 360-day period,
    the Shelf Registration Statement has been declared effective by the
    Commission and such Shelf Registration Statement ceases to be effective
    (without being succeeded on the same day by a post-effective amendment to
    such Shelf Registration Statement that cures such failure and that is
    immediately declared effective) or use of the Prospectus is suspended
    pursuant to Section 4(c); 

(any of the foregoing, a "REGISTRATION DEFAULT").  In the event of any such
Registration Default, the Company shall pay as the sole remedy Liquidated
Damages to each Holder of Transfer Restricted Securities accruing at a rate
equal to 25 basis points (0.25%) per annum on (A) where such Transfer Restricted
Securities are Notes, the aggregate principal amount of such Notes held by such
Holder and (B) where such Transfer Restricted Securities are shares of Common
Stock issued upon conversion of Notes, the aggregate principal amount of Notes
that were converted into such shares, which rate shall in any case increase by
an additional 25 basis points (0.25%) per annum on the first day of any
subsequent 90-day period that the Registration Default remains uncured up to a
maximum rate equal to 100 basis points (1.0%) per annum.  Following the cure of
all Registration Defaults relating to any Transfer Restricted Securities, the
accrual of Liquidated Damages with respect to such Transfer Restricted
Securities will cease (without in any way limiting the effect of any subsequent
Registration Default).  A Registration Default under clause (i) above shall be
cured on the date that the Shelf Registration Statement is filed with the
Commission; a Registration Default under clause (ii) above shall be cured on the
date that the Shelf Registration Statement is declared effective by the
Commission; and a Registration Default under clause (iii) above shall be cured
on the date a post-effective amendment to the Shelf 


                                       7

<PAGE>

Registration Statement is declared effective or suspension of the use of the 
Prospectus is withdrawn.

    (b)  The Company shall notify the Trustee of a Registration Default within
one Business Day after each and every date on which such a Registration Default
occurs.  Liquidated Damages shall be paid by the Company to the Record Holders
on each Damages Payment Date in accordance with the procedures required by the
Indenture for the payment of interest to the various Holders of the Notes, in
the case of the Notes, or by mailing checks to their registered addresses as
they appear in the register of the Company for the Common Stock, in the case of
the Common Stock; PROVIDED, HOWEVER, that any Liquidated Damages accrued with
respect to any Note or portion thereof called for redemption on a redemption
date, repurchased in connection with a Change of Control Offer (as defined in
the Indenture) on a repurchase date, or converted into Common Stock on a
conversion date after which the Record Holders have been determined and prior to
the Damages Payment Date, shall, in any such event, be paid instead to the
holder who submitted such Note or portion thereof for redemption, repurchase or
conversion.  Each obligation to pay Liquidated Damages shall be deemed to
commence accruing on the date of the applicable Registration Default and to
cease accruing when all Registration Defaults have been cured.

    (c)  All of the Company's obligations set forth in this Section 3 which are
outstanding with respect to any Transfer Restricted Securities at the time such
security ceases to be a Transfer Restricted Security shall survive until such
time as all such obligations with respect to such security have been satisfied
in full.

    (d)  Any payments due and payable pursuant to this Section 3 shall be
subject to the provisions of Article XV of the Indenture as if such payments
were additional interest on the Notes.

4.  REGISTRATION PROCEDURES

    (a)  The parties hereto agree that the Transfer Restricted Securities shall
not be sold in any Underwritten Offering and the Company shall in no event be
required to cooperate with or pay for any Underwritten Offering.

    (b)  In connection with the Shelf Registration Statement and any Prospectus
required by this Agreement, during the Effectiveness Period the Company shall:

         (i)   use all reasonable efforts to keep the Shelf Registration
    Statement continuously effective for the Effectiveness Period; upon the
    occurrence of any event that would cause the Shelf Registration Statement
    or the Prospectus contained therein (A) to 


                                       8

<PAGE>

    contain a material misstatement or omission or (B) to not be effective or 
    to not be usable for resales of Transfer Restricted Securities during the
    Effectiveness Period, the Company shall in the case of clause (A) file 
    promptly an appropriate amendment to the Shelf Registration Statement or a
    supplement to the Prospectus correcting any such misstatement or omission,
    and, in the case of either clause (A) or (B), use all reasonable efforts to
    cause such amendment, if applicable, to be declared effective or the Shelf
    Registration Statement and the related Prospectus to become usable for their
    intended purposes as soon as practicable thereafter;

         (ii)  furnish to each of the Initial Purchasers and to counsel for the
    Initial Purchasers, before filing with the Commission, copies of the Shelf
    Registration Statement and the Prospectus included therein, and any 
    pre-effective amendments thereof, which documents shall be subject to the
    review of the Initial Purchasers and such counsel for a period of at least
    five Business Days; and shall consider any requests for additions to or
    modifications of the Shelf Registration Statement and the Prospectus,
    included therein and any pre-effective amendments thereto reasonably made
    by any Initial Purchaser or counsel for the Initial Purchasers;

         (iii) use all reasonable efforts to prepare and file with the
    Commission such amendments and post-effective amendments to the Shelf
    Registration Statement as may be necessary to keep the Shelf Registration
    Statement effective during the Effectiveness Period; use all reasonable
    efforts to cause the Prospectus to be supplemented by any required
    Prospectus supplement within the time period specified in Section 2(b)
    hereof, and as so supplemented, cause the Prospectus to be filed pursuant
    to Rule 424 under the Securities Act and to comply fully with the
    applicable provisions of Rule 424 under the  Securities Act in a timely
    manner; and use all reasonable efforts to comply with the provisions of the
    Securities Act with respect to the disposition of all securities covered by
    the Shelf Registration Statement during the Effectiveness Period in
    accordance with the intended method or methods of distribution by the
    sellers thereof set forth in the Shelf Registration Statement or supplement
    to the Prospectus;

         (iv) use all reasonable efforts to notify the selling Holders promptly
    and, if requested by such Persons, to confirm such advice in writing, (A)
    when the Prospectus, any Prospectus supplement or any post-effective
    amendment to the Shelf Registration Statement applicable to such Holder has
    been filed, and, with respect to the Shelf Registration Statement or any
    post-effective amendment thereto, when the same has become effective, (B)
    of any request by the Commission for amendments to the Shelf Registration
    Statement or amendments or supplements to the Prospectus or for additional
    information relating thereto, (C) of the issuance by the Commission of any
    stop order 


                                       9

<PAGE>

    suspending the effectiveness of the Shelf Registration Statement under 
    the Securities Act or of the suspension by any state securities commission
    of the qualification of the Transfer Restricted Securities for offering or
    sale in any jurisdiction or of the initiation of any proceeding for any of 
    the preceding purposes or (D) of the existence of any fact or of the 
    happening of any event (but not the substance or details of any such fact 
    or event) that makes untrue any statement of a material fact made in the 
    Shelf Registration Statement, the Prospectus, any amendment or supplement 
    thereto or any document incorporated by reference therein, or that requires
    the making of any additions to or changes in the Shelf Registration 
    Statement or the Prospectus in order to make the statements therein not 
    misleading;

         (v)   if at any time the Commission shall issue any stop order
    suspending the effectiveness of the Shelf Registration Statement, or any
    state securities commission shall issue an order suspending the
    qualification or exemption from qualification of the Transfer Restricted
    Securities under state securities or Blue Sky laws, use all reasonable
    efforts to obtain the withdrawal or lifting of such order at the earliest
    possible time;

         (vi)  if requested by any selling Holder, within the time period
    specified in Section 2(b) hereof, use all reasonable efforts to incorporate
    in the Shelf Registration Statement or Prospectus, pursuant to a supplement
    or post-effective amendment, if necessary, such Requisite Information as
    such selling Holders request to have included therein, and use all
    reasonable efforts to make all required filings of any such Prospectus
    supplement or post-effective amendment as soon as practicable after the
    Company is notified of the matters to be incorporated in such Prospectus
    supplement or post-effective amendment; PROVIDED, HOWEVER, that the Company
    shall not be required to take any action pursuant to this Section 4(b)(vi)
    that would, in the opinion of Company Counsel, violate applicable law or to
    include information to which the Company reasonably objects;

         (vii) deliver to each selling Holder, without charge, as many
    copies of the Shelf Registration Statement and the Prospectus (including
    each preliminary prospectus intended for public distribution) (including
    documents incorporated by reference therein and exhibits thereto) and any
    amendment or supplement thereto as such selling Holder reasonably may
    request; subject to Section 4(c) below, the Company hereby consents to the
    use of the Prospectus and any amendment or supplement thereto by each of
    the selling Holders in connection with the offering and the sale of the
    Transfer Restricted Securities covered by the Prospectus or any amendment
    or supplement thereto in conformity with the Plan of Distribution set forth
    in the Prospectus and in compliance with all applicable laws and this
    Agreement;


                                      10

<PAGE>

         (viii) take all such other actions in connection therewith as are
    reasonable and customary in order to expedite or facilitate the disposition
    of the Transfer Restricted Securities pursuant to the Shelf Registration
    Statement contemplated by this Agreement, all to such extent as may be
    reasonably requested by any Initial Purchaser or by any Holder of Transfer
    Restricted Securities in connection with any sale or resale pursuant to the
    Shelf Registration Statement contemplated by this Agreement;

         (ix)   prior to any public offering of Transfer Restricted Securities,
    cooperate with the selling Holders, and their respective counsel in
    connection with the registration and qualification of the Transfer
    Restricted Securities under the securities or Blue Sky laws of such
    domestic jurisdictions as the selling Holders may reasonably request; and
    do any and all other acts or things reasonably necessary or advisable to
    enable the disposition in such jurisdictions of the Transfer Restricted
    Securities covered by the Shelf Registration Statement; PROVIDED, HOWEVER,
    that in no event shall the Company be obligated to (i) qualify as a foreign
    corporation or as a dealer in securities in any jurisdiction where it is
    not now so qualified, (ii) file any general consent to service of process
    in any jurisdiction where it is not as of the date hereof so subject or
    (iii) subject itself to taxation in any jurisdiction if it is not so
    subject;

         (x)    cooperate with the selling Holders to facilitate the timely
    preparation and delivery of certificates representing Transfer Restricted
    Securities to be sold and not bearing any restrictive legends; and enable
    such Transfer Restricted Securities to be in such denominations and
    registered in such names as the selling Holders may request, provided that
    such request is made at least two Business Days prior to any sale of
    Transfer Restricted Securities;

         (xi)   as soon as reasonably practicable after the occurrence of any
    fact or event of the kind described in Section 4(b)(iv)(D) above, use all
    reasonable efforts to prepare a supplement or post-effective amendment to
    the Shelf Registration Statement or related Prospectus or any document
    incorporated therein by reference or file any other required document so
    that, as thereafter delivered to the purchasers of Transfer Restricted
    Securities, the Prospectus shall not contain an untrue statement of a
    material fact or omit to state any material fact necessary, to make the
    statements made therein not misleading in the light of the circumstances in
    which they were made; PROVIDED, HOWEVER, that notwithstanding anything to
    the contrary herein, the Company shall not be required to prepare and file
    such a supplement or post-effective amendment or document if the fact no
    longer exists;


                                      11

<PAGE>


         (xii)  provide a CUSIP number for all Notes (which shall be a
    separate number for any Notes that are not Transfer Restricted Securities)
    not later than the effective date of the Shelf Registration Statement and
    provide the Trustee under the Indenture with printed certificates for the
    Notes that are in a form eligible for deposit with The Depository Trust
    Company;

         (xiii) make generally available to its security holders, in a
    regular filing on Form 10-Q or Form 10-K, a consolidated earnings statement
    meeting the requirements of Rule 158 under the Securities Act (which need
    not be audited) for the twelve-month period commencing after the effective
    date of the Shelf Registration Statement;

         (xiv)  cause the Indenture to be qualified under the TIA not later
    than the effective date of the Shelf Registration Statement and, in
    connection therewith, cooperate with the Trustee and the Holders to effect
    such changes to the Indenture as may be required for such Indenture to be
    so qualified in accordance with the terms of the TIA, and execute, and use
    all reasonable efforts to cause the Trustee to execute, all documents that
    may be required to effect such changes and all other forms and documents
    required to be filed with the Commission to enable such Indenture to be so
    qualified in a timely manner;

         (xv)   cause the Common Stock covered by the Shelf Registration
    Statement to be listed on the Nasdaq Stock Market or such other national
    securities exchange or automated quotation system on which the Common Stock
    is then listed or quoted; and

         (xvi)  provide promptly to each Holder upon request any document
    filed with the Commission pursuant to the requirements of Section 13 and
    Section 15 of the Exchange Act.

    (c)  Each Holder agrees by acquisition of a Transfer Restricted Security
that, upon receipt of any notice from the Company of the existence of any fact
or event of the kind described in Section 4(b)(iv)(D) hereof, such Holder shall:
(i) keep the fact of such notice confidential and (ii) stop selling or offering
for sale Transfer Restricted Securities pursuant to the Shelf Registration
Statement until such Holder's receipt of the copies of a supplemented or amended
Prospectus as contemplated by Section 4(b)(xi) hereof, or until it receives
advice in writing from the Company that the use of the Prospectus may be
resumed, and has received copies of any additional or supplemental filings that
are incorporated by reference in the Prospectus.  If so directed by the Company,
each Holder shall deliver to the Company (at the expense of the Company) all
copies, other than permanent file copies then in such Holder's possession, of
the Prospectus covering such Transfer Restricted Securities that was current at
the time of receipt of such notice.


                                      12

<PAGE>

    (d)  Notwithstanding any provision of this Agreement to the contrary, it
shall not be a breach or violation of any obligation of the Company hereunder if
the Company fails to take any action otherwise required hereunder because, in
its reasonable determination, such action would require the Company to disclose
material, non-public information that the Company has a BONA FIDE business or
legal reason for not disclosing regardless of whether the Company caused such
material, non-public information to exist; PROVIDED, that any suspension of the
use of the Prospectus included in the Shelf Registration Statement as a result
of this Section 4(d) shall not effect the Company's obligation to pay Liquidated
Damages pursuant to Section 3.

    (e)  The Company shall have no obligation to keep a Prospectus usable or to
give notice that a Prospectus is not usable by a particular Holder to the extent
such Prospectus is not usable by such Holder because current Requisite
Information with respect to such Holder is not included therein because such
Holder has not provided such information to the Company in accordance with
Section 2(b).

5.  REGISTRATION EXPENSES

    The following expenses incident to the Company's performance of or
compliance with this Agreement shall be borne by the Company regardless of
whether the Shelf Registration Statement becomes effective: (i) all registration
and filing fees and expenses; (ii) all fees and expenses associated with
compliance with federal securities and state Blue Sky or securities laws; (iii)
all expenses of printing of copying (including printing of any certificates
evidencing the Notes and copying of Prospectuses), messenger and delivery
services and telephone; (iv) all fees and disbursements of Company Counsel; (v)
all application and filing fees in connection with listing any securities on a
national securities exchange or automated quotation system; and (vi) all fees
and disbursements of independent certified public accountants of the Company
(including the expenses of any special audit and comfort letters required by or
incident to such performance).

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

6.  INDEMNIFICATION

         (a)  The Company agrees to indemnify and hold harmless (i) each Holder
and (ii) each person, if any, who controls (within the meaning of Section 15 of
the Securities Act or Section 20(a) of the Exchange Act) any Holder (any of the
persons referred to in this clause (ii) being hereinafter referred to as a
"CONTROLLING PERSON") and (iii) the respective officers, directors, 


                                      13

<PAGE>

partners, employees, representatives and agents of any Holder or any 
controlling person (any person referred to in clause (i), (ii) or (iii) may 
hereinafter be referred to as an "INDEMNIFIED HOLDER"), to the fullest extent 
lawful, from and against any and all losses, liabilities, claims, damages and 
expenses whatsoever as incurred (including but not limited to reasonable 
attorneys' fees and expenses whatsoever incurred in investigating, preparing 
or defending against any litigation, commenced or threatened, or any claim 
whatsoever, and any and all amounts paid in settlement of any claim or 
litigation) (collectively, "LOSSES"), joint or several, to which they or any 
of them may become subject under the Securities Act, the Exchange Act or 
otherwise, insofar as such Losses (or actions in respect thereof) arise out 
of or are based upon any untrue statement or alleged untrue statement of a 
material fact contained in the Shelf Registration Statement or Prospectus or 
any amendment or supplement thereto 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, in light of the 
circumstances under which they were made, not misleading; PROVIDED, HOWEVER, 
that the Company will not be liable in any such case to the extent but only 
to the extent that any such Losses arise out of or are based upon any such 
untrue statement or alleged untrue statement or omission or alleged omission 
made therein in reliance upon and in conformity with written information 
furnished to the Company by any Holder for use therein; and provided further, 
however, that the foregoing indemnity shall not inure to the benefit of any 
Indemnified Holder if the person asserting such Loss (A) purchased a Transfer 
Restricted Security and the Indemnified Holder, or someone acting on the 
Indemnified Holder's behalf, did not deliver to such person at or prior to 
the written confirmation of the sale of such Transfer Restricted Security a 
Prospectus (as then amended or supplemented, if the company furnishes any 
amendments or supplements thereto) and if the Prospectus (as so amended or 
supplemented) would have cured the defect giving rise to such loss, 
liability, claim, damage or expense; or (B) received a Prospectus or an 
amendment or supplement thereto in violation of Section 4(c) of this 
Agreement if such violation caused such Loss.  The Company shall notify the 
Holders promptly of the institution, threat or assertion of any claim, 
proceeding (including any governmental investigation) or litigation in 
connection with the matters addressed by this Agreement that involves the 
company or any Indemnified Holder.

         (b)  In case any action or proceeding (including, without limitation,
any governmental or regulatory investigation or proceeding) shall be brought or
asserted against any of the Indemnified Holders with respect to which indemnity
may be sought against the Company, such Indemnified Holder (or the Indemnified
Holder controlled by such controlling person) shall promptly notify the Company
in writing (PROVIDED that the failure to give such notice shall not relieve the
Company of its obligations pursuant to this Agreement except to the extent the
Company is prejudiced by such failure).  In case any such action is brought
against an Indemnified Holder, and it notifies the Company of the commencement
thereof, the Company will be entitled to participate therein, and to the extent
it elects by written notice delivered to the Indemnified Holder 


                                      14

<PAGE>

promptly after receiving the aforesaid notice from such Indemnified Holder, 
to assume and control the defense thereof with counsel reasonably 
satisfactory to such Indemnified Holder.  Notwithstanding the foregoing, the 
Indemnified Holder shall have the right to employ separate counsel in any 
such action and participate in the defense thereof, but the fees and expenses 
of such counsel shall be at the expense of such Indemnified Holder, PROVIDED 
that the fees and expenses of such counsel shall be at the expense of the 
Company if (i) the Company has failed to assume the defense and employ 
counsel reasonably satisfactory to the Holders or (ii) the named parties to 
any such action (including any impleaded parties) include such Indemnified 
Holder and the Company and such Indemnified Holder shall have reasonably 
concluded that there may be one or more legal defenses available to it that 
are different from or in addition to those available to the Company; 
PROVIDED, FURTHER, that the Company shall not in such event be responsible 
hereunder for the fees and expenses of more than one firm of separate 
counsel, which firm shall be designated by the Holders and shall be subject 
to the Company's approval, not to be unreasonably withheld, in connection 
with any action or separate but related actions in the same jurisdiction, in 
addition to any local counsel.  The Company shall not be liable for any 
settlement of any such action or proceeding effected without the Company's 
prior written consent, which consent shall not be unreasonably withheld or 
delayed, and the Company agrees to indemnify and hold harmless any 
Indemnified Holder from and against any Loss by reason of any settlement of 
any action effected with the Company's written consent.  The Company shall 
not, without the prior written consent of each Indemnified Holder, settle or 
compromise or consent to the entry of a judgment in or otherwise seek to 
terminate any pending or threatened litigation or proceeding in respect of 
which indemnification or contribution may be sought hereunder (whether or not 
any Indemnified Holder is a party thereto), unless such settlement, 
compromise, consent or termination includes an unconditional release of each 
Indemnified Holder from all liability arising out of such action, claim, 
litigation or proceeding.

         (c)  Each Holder of Transfer Restricted Securities agrees, severally
and not jointly, to indemnify and hold harmless the Company, its directors, its
officers, and any person controlling (within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act) the Company, and the
respective officers, directors, partners, employees, representatives and agents
of each such person, to the same extent as the foregoing indemnity from the
Company to each of the Indemnified Holders, but only with respect to claims and
actions based on information relating to such Holder furnished in writing by
such Holder for use in the Shelf Registration Statement or Prospectus.  In case
any action or proceeding shall be brought against any of Company or its
directors or officers or any such controlling person in respect of which
indemnity may be sought against a Holder of Transfer Restricted Securities, such
Holder shall have the rights and duties given the Company, and each of the
Company or its directors or officers of such controlling person shall have the
rights and duties given to each Holder by the preceding paragraph.  In no event
shall the liability of any selling Holder hereunder be greater in amount than


                                      15

<PAGE>

the dollar amount of the proceeds received by such Holder upon the sale of the
securities registered pursuant to provisions hereof giving rise to such
indemnification obligation.

7.  CONTRIBUTION.  

    If the indemnification provided for in Section 6 hereof is unavailable to a
party entitled to indemnification in respect of any Losses referred to therein,
then each indemnifying party, in lieu of indemnifying such indemnified party,
shall contribute to the amount paid or payable by such indemnified party as a
result of such Losses (i) in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Holders on the
other hand from their sale of Transfer Restricted Securities or (ii) if such
allocation is not permitted by applicable law, the relative fault of the Company
on the one hand and of the Indemnified Holder on the other in connection with
the statements or omissions that resulted in such Losses as well as any other
relevant equitable considerations.  The relative fault of the Company on the one
hand of the Indemnified Holder on the other shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Company, or by the Indemnified Holder and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The indemnity and contribution
obligations of each indemnifying party set forth herein shall be in addition to
any liability or obligation such indemnifying party may otherwise have to any
indemnified party, including under this Agreement.

8.  RULE 144A

    The Company hereby agrees with each Holder, during the Effectiveness
Period, to make available to any Holder or beneficial owner of Transfer
Restricted Securities in connection with any sale thereof and any prospective
purchase of such Transfer Restricted Securities from such Holder or beneficial
owner, any information required to be supplied to a Holder by Rule 144A(d)(4)
under the Securities Act (so long as such information is required to permit such
transfer under Rule 144A) in order to permit and sales of such Transfer
Restricted Securities pursuant to Rule 144A.

9.  MISCELLANEOUS

    (a)  REMEDIES.  Each party agrees that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by such party
of the provisions of this Agreement and hereby agrees to waive the defense in
any action for specific performance that a remedy at law would be adequate;
PROVIDED; HOWEVER, that the parties hereto acknowledge and 


                                      16

Liquidated Damages as provided in Section 3 hereto.

    (b)  NO INCONSISTENT AGREEMENTS.  The Company shall not, on or after the
date of this Agreement, enter into any agreement with respect to its securities
that is inconsistent with the rights granted to the Holders in this Agreement or

Holders hereunder are not inconsistent with the rights granted to the holders of
the Company's securities under any agreement in effect on the date hereof.

    (c)  AMENDMENTS AND WAIVERS.  The provisions of this Agreement may not be
amended, modified or supplemented, and waivers or consents to or departures from

                                 CELLSTAR CORPORATION

                      5% Convertible Subordinated Notes Due 2002

         This Note is one of a duly authorized issue of Notes of the Company,
designated as its 5% Convertible Subordinated Notes Due 2002 (herein called the
"Notes"), limited to the aggregate principal amount of $150,000,000 all issued
or to be issued under and pursuant to an Indenture dated as of October 14, 1997
(the "Indenture"), between the Company and The Bank of New York, as trustee (the
"Trustee"), to which Indenture and all indentures supplemental thereto reference
is hereby made for a complete description of the rights, limitations of rights,
obligations, duties and immunities thereunder of the Trustee, the Company and
the holders of the Notes.  Each Note is subject to, and qualified by, all such
terms as set forth in the Indenture, certain of which are summarized hereon and
each holder of a Note is referred to the corresponding provisions of the
Indenture for a complete statement of such terms.  To the extent that there is
any inconsistency between the summary provisions set forth in the Notes and the
Indenture, the provisions of the Indenture shall govern.  Capitalized terms used
but not defined in this Note shall have the meanings ascribed to them in the
Indenture.

         In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest on all Notes may be declared, and upon said declaration shall become,
due and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture.

         The payment of principal of, premium, if any, and interest on the
Notes will, to the extent set forth in the Indenture, be subordinated in right
of payment to the prior payment in full of all Senior Indebtedness (as defined
in the Indenture).  Upon any distribution to creditors of the Company in a
liquidation or dissolution of the Company or in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding relating to the Company or its
property, in an assignment for the benefit of creditors or any marshalling of
the Company's assets and liabilities, (a) holders of Senior Indebtedness shall
be entitled to receive payment in full, in cash or cash equivalents, of all
amounts due or to become due thereon before Holders shall be entitled to receive
any payment or dsitribution of any kind or character, whether in cash, cash
equivalents, property, or securities, on or in respect of the Obligations, 


                                      A-5

<PAGE>

or for the acquisition of any of the Notes for cash, cash equivalents, 
property or securities and (b) until all Senior Indebtedness (as provided in 
clause (a) above) is paid in full, in cash or cash equivalents, any payment 
or distribution to which Holders would be entitled but for the subordination 
provisions of the Indenture shall be made to holders of Senior Indebtedness, 
as their interests may appear.  

         The Company may not make any payment upon or in respect of the Notes
and may not acquire from the Trustee or any Holder any Note for cash, cash
equivalents, property, securities or otherwise until all Senior Indebtedness has
been paid in full, in cash or cash equivalents, if: (a) a Payment Default with
respect to any Senior Indebtedness occurs and is continuing beyond any
applicable period of grace; or (b) a default occurs and is continuing with
respect to any Senior Indebtedness resulting in the acceleration of maturity of
all or any portion of such Senior Indebtedness.  No payment on any of the
Obligations shall be made if, and the Company shall not acquire any Notes while,
any other default (a "nonpayment default") occurs and is continuing (or would
occur upon any payment or distribution with respect to the Obligations) with
respect to Senior Indebtedness that permits holders of the Senior Indebtedness
as to which such default relates to accelerate its maturity and the Trustee
receives a notice of such default (a "Payment Blockage Notice") from the Bank
Representative, Representative or Representatives of holders of at least a
majority in principal amount of Senior Indebtedness then outstanding.

         In the event that the Trustee (or paying agent if other than the
Trustee) or any holder of the Notes receives any payment of principal or
interest with respect to the Notes at a time when such payment is prohibited
under the Indenture, such payment shall be held in trust for the benefit of, and
immediately shall be paid over and delivered to, the holders of Senior
Indebtedness or their Representative as their respective interests may appear. 
After all Senior Indebtedness is paid in full and until the Notes are paid in
full, the holders of the Notes shall be subrogated (equally and ratably with all
other Indebtedness pari passu with the Notes) to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the Notes have
been applied to the payment of Senior Indebtedness.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding, evidenced as
provided in the 


                                      A-6

<PAGE>

Indenture to execute supplemental indentures adding any provisions to or 
changing in any manner or eliminating any of the provisions of the Indenture 
or of any supplemental indenture or modifying in any manner the rights of the 
holders of the Notes; provided that no such supplemental indenture shall (i) 
extend the fixed maturity of any Note, or reduce the rate or extend the time 
of payment of interest thereon, or reduce the principal amount thereof or 
premium, if any, thereon, or reduce any amount payable on redemption thereof, 
alter the obligation of the Company to redeem the Notes at the option of the 
holders upon the occurrence of a Change of Control or impair or affect the 
right of any Holder to institute suit for the payment thereof, or make the 
principal thereof or interest or premium, if any, thereon payable in any coin 
or currency other than that provided in the Notes, modify the subordination 
provisions in a manner adverse to the holders of the Notes, or impair the 
right to convert the Notes into Common Stock subject to the terms set forth 
in the Indenture without the consent of the holder of each Note so affected 
or (ii) reduce the aforesaid percentage of Notes, the holders of which are 
required to consent to any such supplemental indenture, without the consent 
of the holders of all Notes then outstanding.  It is also provided in the 
Indenture that the holders of a majority in aggregate principal amount of the 
Notes at the time outstanding may on behalf of the holders of all of the 
Notes waive any past default or Event of Default under the Indenture and its 
consequences except a default in the payment of interest or any premium on or 
the principal of any of the Notes, a failure by the Company to convert any 
Notes into Common Stock of the Company or a default in respect of a covenant 
or provision of the Indenture that under Article X thereof cannot be modified 
or amended without the consent of the holders of all Notes then outstanding.  
Any such consent or waiver by the holder of this Note (unless revoked as 
provided in the Indenture) shall be conclusive and binding upon such holder 
and upon all future holders and owners of this Note and any Notes that may be 
issued in exchange or substitution hereof, irrespective of whether or not any 
notation thereof is made upon this Note or such other Notes.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the place, at the respective times, at the rate and in the coin
or currency herein prescribed.

         Interest on the Notes shall be computed on the basis of a 360-day year
composed of twelve 30-day months.


                                      A-7

         The Notes are issuable in registered form without coupons in
denominations of $1,000 principal amount and integral multiples thereof.  At the
office or agency of the Company referred to on the face hereof, and in the
manner and subject to the limitations provided in the Indenture, without payment
of any service charge but with payment of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in connection with
any registration or exchange of Notes, Notes may be exchanged for a like
aggregate principal amount of Notes of other authorized denominations.

         The Notes are not redeemable at the option of the Company prior to
October 18, 2000.  At any time on or after that date, the Notes may be redeemed
at the Company's option, upon notice as set forth in the Indenture, in whole at
any time or in part from time to time, at the optional redemption prices set
forth below, together with accrued interest to the date fixed for redemption.

         If redeemed after:
                                                          Redemption

- --------------------------------------------------------------------
- --------------------------------------------------------------------

         If a Change of Control (as defined in the Indenture) shall occur at
any time, then each holder of Notes shall have the right to require that the
Company purchase such holder's Notes in whole or in part in integral multiples
of $1,000, at a purchase price in cash in an amount equal to 101% of the
principal amount of such Notes, plus accrued and unpaid interest, if any, to the
repurchase date pursuant to an offer to be made by the Company and in accordance
with the procedures set forth in the Indenture.

         Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after 60 days following the latest date of
original issuance of the Notes and prior to the close of business on October 11,
2002, or, as to all or any portion hereof called for redemption, prior to the
close of business on the last business day prior to the date fixed for
redemption (unless the Company shall default in payment due upon redemption
thereof), to convert the principal hereof or any portion of such principal that
is $1,000 or an integral multiple thereof, into that number of fully paid and
non-assessable shares of Company's Common Stock, as said shares shall be
constituted at the date of conversion, obtained by dividing the principal amount
of this Note or portion thereof to be converted by the 


                                    A-8

<PAGE>

conversion price of $55.335 or such conversion price as adjusted from time to 
time as provided in the Indenture, upon surrender of this Note, together with 
a conversion notice as provided in the Indenture, to the Company at the 
office or agency of the Company maintained for that purpose in the Borough of 
Manhattan, The City of New York, or at the option of such holder, the 
Corporate Trust Office of the Trustee, and, unless the shares issuable on 
conversion are to be issued in the same name as this Note, duly endorsed by, 
or accompanied by instruments of transfer in form satisfactory to the Company 
duly executed by, the holder or by his duly authorized attorney.  No 
adjustment in respect of interest or dividends will be made upon any 
conversion; provided that if this Note shall be surrendered for conversion 
during the period from the close of business on any record date for the 
payment of interest through the opening of business on the corresponding 
interest payment date, this Note (unless it or the portion being converted 
shall have been called for redemption) must be accompanied by an amount, in 
funds acceptable to the Company, equal to the interest payable on such 
interest payment date on the principal amount being converted.  The interest 
payment with respect to a Note called for redemption on a date during the 
period from the close of business on or after any record date to the close of 
business on the business day following the corresponding payment date will be 
payable on the corresponding interest payment date to the registered Holder 
at the close of business on that record date (notwithstanding the conversion 
of such Note before the close of business on the corresponding interest 
payment date) and a Holder who elects to convert need not include funds equal 
to the interest paid.  No fractional shares will be issued upon any 
conversion, but an adjustment in cash will be made, as provided in the 
Indenture, in respect of any fraction of a share that would otherwise be 
issuable upon the surrender of any Note or Notes for conversion.

         Upon due presentment for registration of transfer of this Note at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, or at the option of the holder of this Note, at the Corporate Trust Office
of the Trustee, a new Note or Notes of authorized denominations for an equal
aggregate principal amount will be issued in the name of the transferee in
exchange thereof, subject to the conditions and limitations provided in the
Indenture, without charge except for any tax, assessment or other governmental
charge imposed in connection therewith.

         The Company, the Trustee, any authenticating agent, any paying agent,
any conversion agent and any Note registrar may deem and treat the registered
holder hereof as the absolute owner of this Note (whether or not this 


                                    A-9

<PAGE>

Note shall be overdue and notwithstanding any notation of ownership or other 
writing hereon made by anyone other than the Company or any Note registrar), 
for the purpose of receiving payment hereof, or on account hereof, for the 
conversion hereof and for all other purposes, and neither the Company nor the 
Trustee nor any authenticating agent nor any paying agent nor any conversion 
agent nor any Note registrar shall be affected by any notice to the contrary. 
All payments made to or upon the order of such registered holder shall, to 
the extent of the sum or sums paid, satisfy and discharge liability for 
monies payable on this Note.

         No recourse for the payment of the principal of or any premium or
interest on this Note, or for any claim based hereon or otherwise in respect
hereof, and no recourse under or upon any obligation, covenant or agreement of
the Company in the Indenture or any indenture supplemental thereto or in any
Note, or because of the creation of any indebtedness represented thereby, shall

                  5% Convertible Subordinated Notes Due 2002

         This Restricted Global Note is one of a duly authorized issue of 
Notes of the Company, designated as its 5% Convertible Subordinated Notes Due 
2002 (herein called the "Notes"), limited to the aggregate principal amount 
of $150,000,000 all issued or to be issued under and pursuant to an Indenture 
dated as of October 14, 1997 (the "Indenture"), between the Company and The 
Bank of New York, as trustee (the "Trustee"), to which Indenture and all 
indentures supplemental thereto reference is hereby made for a complete 
description of the rights, limitations of rights, obligations, duties and 
immunities thereunder of the Trustee, the Company and the holders of the 
Notes.  Each Note is subject to, and qualified by, all such terms as set 
forth in the Indenture, certain of which are summarized hereon and each 
holder of a Note is referred to the corresponding provisions of the Indenture 
for a complete statement of such terms.  To the extent that there is any 
inconsistency between the summary provisions set forth in the Notes and the 
Indenture, the provisions of the Indenture shall govern. Capitalized terms 
used but not defined in this Note shall have the meanings ascribed to them in 
the Indenture.

         In case an Event of Default (as defined in the Indenture) shall have 
occurred and be continuing, the principal of, premium, if any, and accrued 
interest on all Notes may be declared, and upon said declaration shall 
become, due and payable, in the manner, with the effect and subject to the 
conditions provided in the Indenture.

         The payment of principal of, premium, if any, and interest on the 
Notes will, to the extent set forth in the Indenture, be subordinated in 
right of payment to the prior payment in full of all Senior Indebtedness (as 
defined in the Indenture).  Upon any distribution to creditors of the Company 
in a liquidation or dissolution of the Company or in a bankruptcy, 
reorganization, insolvency, receivership or similar proceeding relating to 
the Company or its property, in an assignment for the benefit of creditors or 
any marshalling of the Company's assets and liabilities, (a) holders of 
Senior Indebtedness shall be entitled to receive payment in full, in cash or 
cash equivalents, of all amounts due or to become due thereon before Holders 
shall be entitled to receive any payment or distribution of any kind or 
character, whether in 

                                       6
<PAGE>

cash, cash equivalents, property, or securities, on or in respect of the 
Obligations, or for the acquisition of any of the Notes for cash, cash 
equivalents, property or securities and (b) until all Senior Indebtedness (as 
provided in clause (a) above) is paid in full, in cash or cash equivalents, 
any payment or distribution to which Holders would be entitled but for the 
subordination provisions of the Indenture shall be made to holders of Senior 
Indebtedness, as their interests may appear.  

         The Company may not make any payment upon or in respect of the Notes 
and may not acquire from the Trustee or any Holder any Note for cash, cash 
equivalents, property, securities or otherwise until all Senior Indebtedness 
has been paid in full, in cash or cash equivalents, if: (a) a Payment 
Default with respect to any Senior Indebtedness occurs and is continuing 
beyond any applicable period of grace; or (b) a default occurs and is 
continuing with respect to any Senior Indebtedness resulting in the 
acceleration of maturity of all or any portion of such Senior Indebtedness.  
No payment on any of the Obligations shall be made if, and the Company shall 
not acquire any Notes while, any other default (a "nonpayment default") 
occurs and is continuing (or would occur upon any payment or distribution 
with respect to the Obligations) with respect to Senior Indebtedness that 
permits holders of the Senior Indebtedness as to which such default relates 
to accelerate its maturity and the Trustee receives a notice of such default 
(a "Payment Blockage Notice") from the Bank Representative, Representative or 
Representatives of holders of at least a majority in principal amount of 
Senior Indebtedness then outstanding.

         In the event that the Trustee (or paying agent if other than the 
Trustee) or any holder of the Notes receives any payment of principal or 
interest with respect to the Notes at a time when such payment is prohibited 
under the Indenture, such payment shall be held in trust for the benefit of, 
and shall immediately be paid over and delivered to, the holders of Senior 
Indebtedness or their Representative as their respective interests may 
appear. After all Senior Indebtedness is paid in full and until the Notes are 
paid in full, the holders of the Notes shall be subrogated (equally and 
ratably with all other Indebtedness pari passu with the Notes) to the rights 
of holders of Senior Indebtedness to receive distributions applicable to 
Senior Indebtedness to the extent that distributions otherwise payable to the 
holders of the Notes have been applied to the payment of Senior Indebtedness.

         The Indenture contains provisions permitting the Company and the 
Trustee, with the consent of the holders of not less than a majority in 
aggregate 

                                       7

principal amount of the Notes at the time outstanding, evidenced as provided 
in the Indenture to execute supplemental indentures adding any provisions to 
or changing in any manner or eliminating any of the provisions of the 
Indenture or of any supplemental indenture or modifying in any manner the 
rights of the holders of the Notes; provided that no such supplemental 
indenture shall (i) extend the fixed maturity of any Note, or reduce the rate 
or extend the time of payment of interest thereon, or reduce the principal 
amount thereof or premium, if any, thereon, or reduce any amount payable on 
redemption thereof, alter the obligation of the Company to redeem the Notes 
at the option of the holders upon the occurrence of a Change of Control or 
impair or affect the right of any Holder to institute suit for the payment 
thereof, or make the principal thereof or interest or premium, if any, 
thereon payable in any coin or currency other than that provided in the 
Notes, modify the subordination provisions in a manner adverse to the holders 
of the Notes, or impair the right to convert the Notes into Common Stock 
subject to the terms set forth in the Indenture without the consent of the 
holder of each Note so affected or (ii) reduce the aforesaid percentage of 
Notes, the holders of which are required to consent to any such supplemental 
indenture, without the consent of the holders of all Notes then outstanding.  
It is also provided in the Indenture that the holders of a majority in 
aggregate principal amount of the Notes at the time outstanding may on behalf 
of the holders of all of the Notes waive any past default or Event of Default 
under the Indenture and its consequences except a default in the payment of 
interest or any premium on or the principal of any of the Notes, a failure by 
the Company to convert any Notes into Common Stock of the Company or a 
default in respect of a covenant or provision of the Indenture that under 
Article X thereof cannot be modified or amended without the consent of the 
holders of all Notes then outstanding.  Any such consent or waiver by the 
holder of this Note (unless revoked as provided in the Indenture) shall be 
conclusive and binding upon such holder and upon all future holders and 
owners of this Note and any Notes that may be issued in exchange or 
substitution hereof, irrespective of whether or not any notation thereof is 
made upon this Note or such other Notes.

         No reference herein to the Indenture and no provision of this Note 
or of the Indenture shall alter or impair the obligation of the Company, 
which is absolute and unconditional, to pay the principal of and any premium 
and interest on this Note at the place, at the respective times, at the rate 
and in the coin or currency herein prescribed.

         Interest on the Notes shall be computed on the basis of a 360-day 
year composed of twelve 30-day months.

                                       8

         The Notes are issuable in registered form without coupons in 
denominations of $1,000 principal amount and integral multiples thereof.  At 
the office or agency of the Company referred to on the face hereof, and in 
the manner and subject to the limitations provided in the Indenture, without 
payment of any service charge but with payment of a sum sufficient to cover 
any tax, assessment or other governmental charge that may be imposed in 
connection with any registration or exchange of Notes, Notes may be exchanged 
for a like aggregate principal amount of Notes of other authorized 
denominations.

         The Notes are not redeemable at the option of the Company prior to 
October 18, 2000.  At any time on or after that date, the Notes may be 
redeemed at the Company's option, upon notice as set forth in the Indenture, 
in whole at any time or in part from time to time, at the optional redemption 
prices set forth below, together with accrued interest to the date fixed for 
redemption.

         If redeemed after:

October 18, 2000                                                       102%

- ------------------------------------------------------------------------------
- ------------------------------------------------------------------------------

         If a Change of Control (as defined in the Indenture) shall occur at 
any time, then each holder of Notes shall have the right to require that the 
Company purchase such holder's Notes in whole or in part in integral 
multiples of $1,000, at a purchase price in cash in an amount equal to 101% 
of the principal amount of such Notes, plus accrued and unpaid interest, if 
any, to the repurchase date pursuant to an offer to be made by the Company 
and in accordance with the procedures set forth in the Indenture.

         Subject to the provisions of the Indenture, the holder hereof has 
the right, at its option, at any time after 60 days following the latest date 
of original issuance of the Notes and prior to the close of business on 
October 11, 2002, or, as to all or any portion hereof called for redemption, 
prior to the close of business on the last business day prior to the date 
fixed for redemption (unless the Company shall default in payment due upon 
redemption thereof), to convert the principal hereof or any portion of such 
principal that is $1,000 or an integral multiple thereof, into that number of 
fully paid and non-assessable shares of the Company's Common Stock, as said 
shares shall be constituted at the date of conversion, obtained by dividing 
the principal amount of this Note or portion thereof to be converted by the 

                                       9
<PAGE>

conversion price of $55.335 or such conversion price as adjusted from time to 
time as provided in the Indenture, upon surrender of this Note, together with 
a conversion notice as provided in the Indenture, to the Company at the 
office or agency of the Company maintained for that purpose in the Borough of 
Manhattan, The City of New York, or at the option of such holder, the 
Corporate Trust Office of the Trustee, and, unless the shares issuable on 
conversion are to be issued in the same name as this Note, duly endorsed by, 
or accompanied by instruments of transfer in form satisfactory to the Company 
duly executed by, the holder or by his duly authorized attorney.  No 
adjustment in respect of interest or dividends will be made upon any 
conversion; provided that if this Note shall be surrendered for conversion 
during the period from the close of business on any record date for the 
payment of interest through the opening of business on the corresponding 
interest payment date, this Note (unless it or the portion being converted 
shall have been called for redemption) must be accompanied by an amount, in 
funds acceptable to the Company, equal to the interest payable on such 
interest payment date on the principal amount being converted.  The interest 
payment with respect to a Note called for redemption on a date during the 
period from the close of business on or after any record date to the close of 
business on the business day following the corresponding payment date will be 
payable on the corresponding interest payment date to the registered Holder 
at the close of business on that record date (notwithstanding the conversion 
of such Note before the close of business on the corresponding interest 
payment date) and a Holder who elects to convert need not include funds equal 
to the interest paid.  No fractional shares will be issued upon any 
conversion, but an adjustment in cash will be made, as provided in the 
Indenture, in respect of any fraction of a share that would otherwise be 
issuable upon the surrender of any Note or Notes for conversion.

         Upon due presentment for registration of transfer of this Note at 
the office or agency of the Company in the Borough of Manhattan, The City of 
New York, or at the option of the holder of this Note, at the Corporate Trust 
Office of the Trustee, a new Note or Notes of authorized denominations for an 
equal aggregate principal amount will be issued in the name of the transferee 
in exchange thereof, subject to the conditions and limitations provided in 
the Indenture, without charge except for any tax, assessment or other 
governmental charge imposed in connection therewith.

         The Company, the Trustee, any authenticating agent, any paying 
agent, any conversion agent and any Note registrar may deem and treat the 
registered holder hereof as the absolute owner of this Note (whether or not 
this Note shall be overdue 

                                      10

and notwithstanding any notation of ownership or other writing hereon made by 
anyone other than the Company or any Note registrar), for the purpose of 
receiving payment hereof, or on account hereof, for the conversion hereof and 
for all other purposes, and neither the Company nor the Trustee nor any 
authenticating agent nor any paying agent nor any conversion agent nor any 
Note registrar shall be affected by any notice to the contrary.  All payments 
made to or upon the order of such registered holder shall, to the extent of 
the sum or sums paid, satisfy and discharge liability for monies payable on 
this Note.

         No recourse for the payment of the principal of or any premium or 
interest on this Note, or for any claim based hereon or otherwise in respect 
hereof, and no recourse under or upon any obligation, covenant or agreement 
of the Company in the Indenture or any indenture supplemental thereto or in 
any Note, or because of the creation of any indebtedness represented thereby, 
shall be had against any incorporator, stockholder, officer or director, as 
such, past, present or future, of the Company or of any Successor Company, 
either directly or through the Company or any Successor Company, whether by 
virtue of any constitution, statute or rule of law or by the enforcement of 
any assessment or penalty or otherwise, all such liability being, by the 
acceptance hereof and as part of the consideration for the issue hereof, 
expressly waived and released.

                  5% Convertible Subordinated Notes Due 2002

         This Restricted Global Note is one of a duly authorized issue of Notes
of the Company, designated as its 5% Convertible Subordinated Notes Due 2002
(herein called the "Notes"), limited to the aggregate principal amount of
$150,000,000 all issued or to be issued under and pursuant to an Indenture dated
as of October 14, 1997 (the "Indenture"), between the Company and The Bank of
New York, as trustee (the "Trustee"), to which Indenture and all indentures
supplemental thereto reference is hereby made for a complete description of the
rights, limitations of rights, obligations, duties and immunities thereunder of
the Trustee, the Company and the holders of the Notes.  Each Note is subject to,
and qualified by, all such terms as set forth in the Indenture, certain of which
are summarized hereon and each holder of a Note is referred to the corresponding
provisions of the Indenture for a complete statement of such terms.  To the
extent that there is any inconsistency between the summary provisions set forth
in the Notes and the Indenture, the provisions of the Indenture shall govern. 
Capitalized terms used but not defined in this Note shall have the meanings
ascribed to them in the Indenture.

         In case an Event of Default (as defined in the Indenture) shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest on all Notes may be declared, and upon said declaration shall become,
due and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture.

         The payment of principal of, premium, if any, and interest on the
Notes will, to the extent set forth in the Indenture, be subordinated in right
of payment to the prior payment in full of all Senior Indebtedness (as defined
in the Indenture).  Upon any distribution to creditors of the Company in a
liquidation or dissolution of the Company or in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding relating to the Company or its
property, in an assignment for the benefit of creditors or any marshalling of
the Company's assets and liabilities, (a) holders of Senior Indebtedness shall
be entitled to receive payment in full, in cash or cash equivalents, of all
amounts due or to become due thereon before Holders shall be entitled to receive
any payment or distribution of any kind or character, whether in 


                                       6

<PAGE>

cash, cash equivalents, property, or securities, on or in respect of the 
Obligations, or for the acquisition of any of the Notes for cash, cash 
equivalents, property or securities and (b) until all Senior Indebtedness (as 
provided in clause (a) above) is paid in full, in cash or cash equivalents, 
any payment or distribution to which Holders would be entitled but for the 
subordination provisions of the Indenture shall be made to holders of Senior 
Indebtedness, as their interests may appear.  

         The Company may not make any payment upon or in respect of the Notes
and may not acquire from the Trustee or any Holder any Note for cash, cash
equivalents, property, securities or otherwise until all Senior Indebtedness has
been paid in full, in cash or cash equivalents, if:   (a) a Payment Default
with respect to any Senior Indebtedness occurs and is continuing beyond any
applicable period of grace; or (b) a default occurs and is continuing with
respect to any Senior Indebtedness resulting in the acceleration of maturity of
all or any portion of such Senior Indebtedness.  No payment on any of the
Obligations shall be made if, and the Company shall not acquire any Notes while,
any other default (a "nonpayment default") occurs and is continuing (or would
occur upon any payment or distribution with respect to the Obligations) with
respect to Senior Indebtedness that permits holders of the Senior Indebtedness
as to which such default relates to accelerate its maturity and the Trustee
receives a notice of such default (a "Payment Blockage Notice") from the Bank
Representative, Representative or Representatives of holders of at least a
majority in principal amount of Senior Indebtedness then outstanding.

         In the event that the Trustee (or paying agent if other than the
Trustee) or any holder of the Notes receives any payment of principal or
interest with respect to the Notes at a time when such payment is prohibited
under the Indenture, such payment shall be held in trust for the benefit of, and
shall immediately be paid over and delivered to, the holders of Senior
Indebtedness or their Representative as their respective interests may appear. 
After all Senior Indebtedness is paid in full and until the Notes are paid in
full, the holders of the Notes shall be subrogated (equally and ratably with all
other Indebtedness pari passu with the Notes) to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the Notes have
been applied to the payment of Senior Indebtedness.


                                       7

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate principal amount of the Notes at the time outstanding, evidenced as
provided in the Indenture to execute supplemental indentures adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of any supplemental indenture or modifying in any manner the
rights of the holders of the Notes; provided that no such supplemental indenture
shall (i) extend the fixed maturity of any Note, or reduce the rate or extend
the time of payment of interest thereon, or reduce the principal amount thereof
or premium, if any, thereon, or reduce any amount payable on redemption thereof,
alter the obligation of the Company to redeem the Notes at the option of the
holders upon the occurrence of a Change of Control or impair or affect the right
of any Holder to institute suit for the payment thereof, or make the principal
thereof or interest or premium, if any, thereon payable in any coin or currency
other than that provided in the Notes, modify the subordination provisions in a
manner adverse to the holders of the Notes, or impair the right to convert the
Notes into Common Stock subject to the terms set forth in the Indenture without
the consent of the holder of each Note so affected or (ii) reduce the aforesaid
percentage of Notes, the holders of which are required to consent to any such
supplemental indenture, without the consent of the holders of all Notes then
outstanding.  It is also provided in the Indenture that the holders of a
majority in aggregate principal amount of the Notes at the time outstanding may
on behalf of the holders of all of the Notes waive any past default or Event of
Default under the Indenture and its consequences except a default in the payment
of interest or any premium on or the principal of any of the Notes, a failure by
the Company to convert any Notes into Common Stock of the Company or a default
in respect of a covenant or provision of the Indenture that under Article X
thereof cannot be modified or amended without the consent of the holders of all
Notes then outstanding.  Any such consent or waiver by the holder of this Note
(unless revoked as provided in the Indenture) shall be conclusive and binding
upon such holder and upon all future holders and owners of this Note and any
Notes that may be issued in exchange or substitution hereof, irrespective of
whether or not any notation thereof is made upon this Note or such other Notes.

         No reference herein to the Indenture and no provision of this Note or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and any premium and interest
on this Note at the place, at the respective times, at the rate and in the coin
or currency herein prescribed.


                                       8

<PAGE>

         Interest on the Notes shall be computed on the basis of a 360-day year
composed of twelve 30-day months.

         The Notes are issuable in registered form without coupons in
denominations of $1,000 principal amount and integral multiples thereof.  At the
office or agency of the Company referred to on the face hereof, and in the
manner and subject to the limitations provided in the Indenture, without payment
of any service charge but with payment of a sum sufficient to cover any tax,
assessment or other governmental charge that may be imposed in connection with
any registration or exchange of Notes, Notes may be exchanged for a like
aggregate principal amount of Notes of other authorized denominations.

         The Notes are not redeemable at the option of the Company prior to
October 18, 2000.  At any time on or after that date, the Notes may be redeemed
at the Company's option, upon notice as set forth in the Indenture, in whole at
any time or in part from time to time, at the optional redemption prices set
forth below, together with accrued interest to the date fixed for redemption.

         If redeemed after: 

                                                                Redemption
Date                                                              Price
- ----                                                            ----------
October 18, 2000...........................................        102%
October 15, 2001...........................................        101%
- --------------------------------------------------------------------------
- --------------------------------------------------------------------------

         If a Change of Control (as defined in the Indenture) shall occur at
any time, then each holder of Notes shall have the right to require that the
Company purchase such holder's Notes in whole or in part in integral multiples
of $1,000, at a purchase price in cash in an amount equal to 101% of the
principal amount of such Notes, plus accrued and unpaid interest, if any, to the
repurchase date pursuant to an offer to be made by the Company and in accordance
with the procedures set forth in the Indenture.

         Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after 60 days following the latest date of
original issuance of the Notes and prior to the close of business on October 11,
2002, or, as to all or any portion hereof called for redemption, prior to the
close of business on the last business date prior to the date fixed for
redemption (unless the Company shall default in payment due upon redemption
thereof), to convert the principal hereof or any portion of such principal that
is $1,000 or an integral multiple thereof, 


                                       9

<PAGE>

into that number of fully paid and non-assessable shares of the Company's 
Common Stock, as said shares shall be constituted at the date of conversion, 
obtained by dividing the principal amount of this Note or portion thereof to 
be converted by the conversion price of $55.335 or such conversion price as 
adjusted from time to time as provided in the Indenture, upon surrender of 
this Note, together with a conversion notice as provided in the Indenture, to 
the Company at the office or agency of the Company maintained for that 
purpose in the Borough of Manhattan, The City of New York, or at the option 
of such holder, the Corporate Trust Office of the Trustee, and, unless the 
shares issuable on conversion are to be issued in the same name as this Note, 
duly endorsed by, or accompanied by instruments of transfer in form 
satisfactory to the Company duly executed by, the holder or by his duly 
authorized attorney.  No adjustment in respect of interest or dividends will 
be made upon any conversion; provided that if this Note shall be surrendered 
for conversion during the period from the close of business on any record 
date for the payment of interest through the opening of business on the 
corresponding interest payment date, this Note (unless it or the portion 
being converted shall have been called for redemption) must be accompanied by 
an amount, in funds acceptable to the Company, equal to the interest payable 
on such interest payment date on the principal amount being converted.  The 
interest payment with respect to a Note called for redemption on a date 
during the period from the close of business on or after any record date to 
the close of business on the business day following the corresponding payment 
date will be payable on the corresponding interest payment date to the 
registered Holder at the close of business on that record date 
(notwithstanding the conversion of such Note before the close of business on 
the  corresponding interest payment date) and a Holder who elects to convert 
need not include funds equal to the interest paid.  No fractional shares will 
be issued upon any conversion, but an adjustment in cash will be made, as 
provided in the Indenture, in respect of any fraction of a share that would 
otherwise be issuable upon the surrender of any Note or Notes for conversion.

         Upon due presentment for registration of transfer of this Note at the
office or agency of the Company in the Borough of Manhattan, The City of New
York, or at the option of the holder of this Note, at the Corporate Trust Office
of the Trustee, a new Note or Notes of authorized denominations for an equal
aggregate principal amount will be issued in the name of the transferee in
exchange thereof, subject to the conditions and limitations provided in the
Indenture, without charge except for any tax, assessment or other governmental
charge imposed in connection therewith.

                            CELLSTAR CORPORATION

                 5% Convertible Subordinated Notes Due 2002

         This Regulation S Global Note is one of a duly authorized issue of
Notes of the Company, designated as its 5% Convertible Subordinated Notes Due
2002 (herein called the "Notes"), limited to the aggregate principal amount of
$150,000,000 all issued or to be issued under and pursuant to an Indenture dated
as of October 14, 1997 (the "Indenture"), between the Company and The Bank of
New York, as trustee (the "Trustee"), to which Indenture and all indentures
supplemental thereto reference is hereby made for a complete description of the
rights, limitations of rights, obligations, duties and immunities thereunder of
the Trustee, the Company and the holders of the Notes.  Each Note is subject to,
and qualified by, all such terms as set forth in the Indenture, certain of which
are summarized hereon and each holder of a Note is referred to the corresponding
provisions of the Indenture for a complete statement of such terms.  To the
extent that there is any inconsistency between the summary provisions set forth
in the Notes and the Indenture, the provisions of the Indenture shall govern.
Capitalized terms used but not defined in this Note shall have the meanings
ascribed to them in the Indenture.

         In case an Event of Default (as defined in the Indenture) shall have
occurred and be continuing, the principal of, premium, if any, and accrued
interest on all Notes may be declared, and upon said declaration shall become,
due and payable, in the manner, with the effect and subject to the conditions
provided in the Indenture.

         The payment of principal of, premium, if any, and interest on the
Notes will, to the extent set forth in the Indenture, be subordinated in right
of payment to the prior payment in full of all Senior Indebtedness (as defined
in the Indenture).  Upon any distribution to creditors of the Company in a
liquidation or dissolution of the Company or in a bankruptcy, reorganization,
insolvency, receivership or similar proceeding relating to the Company or its
property, in an assignment for the benefit of creditors or any marshalling of
the Company's assets and liabilities, (a) holders of Senior Indebtedness shall
be entitled to receive payment in full, in cash or cash equivalents, of all
amounts due or to become due thereon before Holders shall be entitled to receive
any payment or distribution of any kind or character, whether in 

                                     6
<PAGE>

cash, cash equivalents, property, or securities, on or in respect of the 
Obligations, or for the acquisition of any of the Notes for cash, cash 
equivalents, property or securities and (b) until all Senior Indebtedness (as 
provided in clause (a) above) is paid in full, in cash or cash equivalents, 
any payment or distribution to which Holders would be entitled but for the 
subordination provisions of the Indenture shall be made to holders of Senior 
Indebtedness, as their interests may appear.

         The Company may not make any payment upon or in respect of the Notes
and may not acquire from the Trustee or any Holder any Note for cash, cash
equivalents, property, securities or otherwise until all Senior Indebtedness 
has been paid in full, in cash or cash equivalents, if: (a) a Payment Default
with respect to any Senior Indebtedness occurs and is continuing beyond any
applicable period of grace; or (b) a default occurs and is continuing with
respect to any Senior Indebtedness resulting in the acceleration of maturity of
all or any portion of such Senior Indebtedness.  No payment on any of the
Obligations shall be made if, and the Company shall not acquire any Notes while,
any other default (a "nonpayment default") occurs and is continuing (or would
occur upon any payment or distribution with respect to the Obligations) with
respect to Senior Indebtedness that permits holders of the Senior Indebtedness
as to which such default relates to accelerate its maturity and the Trustee
receives a notice of such default (a "Payment Blockage Notice") from the Bank
Representative, Representative or Representatives of holders of at least a
majority in principal amount of Senior Indebtedness then outstanding.

         In the event that the Trustee (or paying agent if other than the
Trustee) or any holder of the Notes receives any payment of principal or
interest with respect to the Notes at a time when such payment is prohibited
under the Indenture, such payment shall be held in trust for the benefit of, and
shall be immediately paid over and delivered to, the holders of Senior
Indebtedness or their representative as their respective interests may appear.
After all Senior Indebtedness is paid in full and until the Notes are paid in
full, the holders of the Notes shall be subrogated (equally and ratably with all
other Indebtedness pari passu with the Notes) to the rights of holders of Senior
Indebtedness to receive distributions applicable to Senior Indebtedness to the
extent that distributions otherwise payable to the holders of the Notes have
been applied to the payment of Senior Indebtedness.

         The Indenture contains provisions permitting the Company and the
Trustee, with the consent of the holders of not less than a majority in
aggregate 

                                     7
<PAGE>

principal amount of the Notes at the time outstanding, evidenced as provided 
in the Indenture to execute supplemental indentures adding any provisions to 
or changing in any manner or eliminating any of the provisions of the 
Indenture or of any supplemental indenture or modifying in any manner the 
rights of the holders of the Notes; provided that no such supplemental 
indenture shall (i) extend the fixed maturity of any Note, or reduce the rate 
or extend the time of payment of interest thereon, or reduce the principal 
amount thereof or premium, if any, thereon, or reduce any amount payable on 
redemption thereof, alter the obligation of the Company to redeem the Notes 
at the option of the holders upon the occurrence of a Change of Control or 
impair or affect the right of any Holder to institute suit for the payment 
thereof, or make the principal thereof or interest or premium, if any, 
thereon payable in any coin or currency other than that provided in the 
Notes, modify the subordination provisions in a manner adverse to the holders 
of the Notes, or impair the right to convert the Notes into Common Stock 
subject to the terms set forth in the Indenture without the consent of the 
holder of each Note so affected or (ii) reduce the aforesaid percentage of 
Notes, the holders of which are required to consent to any such supplemental 
indenture, without the consent of the holders of all Notes then outstanding.  
It is also provided in the Indenture that the holders of a majority in

of the holders of all of the Notes waive any past default or Event of Default 
under the Indenture and its consequences except a default in the payment of 
interest or any premium on or the principal of any of the Notes, a failure by 
the Company to convert any Notes into Common Stock of the Company or a 
default in respect of a covenant or provision of the Indenture that under 
Article X thereof cannot be modified or amended without the consent of the 
holders of all Notes then outstanding.  Any such consent or waiver by the 
holder of this Note (unless revoked as provided in the Indenture) shall be 
conclusive and binding upon such holder and upon all future holders and 
owners of this Note and any Notes that may be issued in exchange or 
substitution hereof, irrespective of whether or not any notation thereof is

or currency herein prescribed.

         The Notes are issuable in registered form without coupons in 
denominations of $1,000 principal amount and integral multiples thereof.  At 
the office or agency of the Company referred to on the face hereof, and in 
the manner and subject to the limitations provided in the Indenture, without 
payment of any service charge but with payment of a sum sufficient to cover 
any tax, assessment or other governmental charge that may be imposed in 
connection with any registration or exchange of Notes, Notes may be exchanged 
for a like aggregate principal amount of Notes of other authorized 
denominations.

         The Notes are not redeemable at the option of the Company prior to 
October 18, 2000.  At any time on or after that date, the Notes may be 
redeemed at the Company's option, upon notice as set forth in the Indenture, 
in whole at any time or in part from time to time, at the optional redemption 
prices set forth below, together with accrued interest to the date fixed for 
redemption.

         If redeemed after: 

                                                                 Redemption

         If a Change of Control (as defined in the Indenture) shall occur at 
any time, then each holder of Notes shall have the right to require that the 
Company purchase such holder's Notes in whole or in part in integral 
multiples of $1,000, at a purchase price in cash in an amount equal to 101% 
of the principal amount of such Notes, plus accrued and unpaid interest, if 
any, to the repurchase date pursuant to an offer to be made by the Company 
and in accordance with the procedures set forth in the Indenture.

         Subject to the provisions of the Indenture, the holder hereof has 
the right, at its option, at any time after 60 days following the latest date 
of original issuance of the Notes and prior to the close of business on 
October 11, 2002, or, as to all or any portion hereof called for redemption, 
prior to the close of business on the last business day prior to the date 
fixed for redemption (unless the Company shall default in payment due upon 
redemption thereof), to convert the principal hereof or any portion of such 
principal that is $1,000 or an integral multiple thereof, into that number of 
fully paid and non-assessable shares of the Company's Common Stock, as said 
shares shall be constituted at the date of conversion, obtained by dividing 
the principal amount of this Note or portion thereof to be converted by the 

                                       9
<PAGE>

conversion price of $55.335 or such conversion price as adjusted from time to 
time as provided in the Indenture, upon surrender of this Note, together with 
a conversion notice as provided in the Indenture, to the Company at the 
office or agency of the Company maintained for that purpose in the Borough of 
Manhattan, The City of New York, or at the option of such holder, the 
Corporate Trust Office of the Trustee, and, unless the shares issuable on 
conversion are to be issued in the same name as this Note, duly endorsed by, 
or accompanied by instruments of transfer in form satisfactory to the Company 
duly executed by, the holder or by his duly authorized attorney.  No 
adjustment in respect of interest or dividends will be made upon any 
conversion; provided that if this Note shall be surrendered for conversion 
during the period from the close of business on any record date for the 
payment of interest through the opening of business on the corresponding 
interest payment date, this Note (unless it or the portion being converted 
shall have been called for redemption) must be accompanied by an amount, in 
funds acceptable to the Company, equal to the interest payable on such 
interest payment date on the principal amount being converted.  The interest 
payment with respect to a Note called for redemption on a date during the 
period from the close of business on or after any record date to the close of 
business on the business day following the corresponding payment date will be 
payable on the corresponding interest payment date to the registered Holder 
at the close of business on that record date (notwithstanding the conversion 
of such Note before the close of business on the corresponding interest 
payment date) and a Holder who elects to convert need not include funds equal 
to the interest paid.  No fractional shares will be issued upon any 
conversion, but an adjustment in cash will be made, as provided in the 
Indenture, in respect of any fraction of a share that would otherwise be 
issuable upon the surrender of any Note or Notes for conversion.

         Upon due presentment for registration of transfer of this Note at 
the office or agency of the Company in the Borough of Manhattan, The City of 
New York, or at the option of the holder of this Note, at the Corporate Trust 
Office of the Trustee, a new Note or Notes of authorized denominations for an 
equal aggregate principal amount will be issued in the name of the transferee 
in exchange thereof, subject to the conditions and limitations provided in 
the Indenture, without charge except for any tax, assessment or other 
governmental charge imposed in connection therewith.

         The Company, the Trustee, any authenticating agent, any paying 
agent, any conversion agent and any Note registrar may deem and treat the 
registered holder hereof as the absolute owner of this Note (whether or not 
this Note shall be overdue and notwithstanding any notation of ownership or 
other 

                                      10

writing hereon made by anyone other than the Company or any Note registrar), 
for the purpose of receiving payment hereof, or on account hereof, for the 
conversion hereof and for all other purposes, and neither the Company nor the 
Trustee nor any authenticating agent nor any paying agent nor any conversion 
agent nor any Note registrar shall be affected by any notice to the contrary. 
 All payments made to or upon the order of such registered holder shall, to 
the extent of the sum or sums paid, satisfy and discharge liability for 
monies payable on this Note.

         No recourse for the payment of the principal of or any premium or 
interest on this Note, or for any claim based hereon or otherwise in respect 
hereof, and no recourse under or upon any obligation, covenant or agreement 
of the Company in the Indenture or any indenture supplemental thereto or in 
any Note, or because of the creation of any indebtedness represented thereby, 
shall be had against any incorporator, stockholder, officer or director, as 
such, past, present or future, of the Company or of any Successor Company, 
either directly or through the Company or any Successor Company, whether by 
virtue of any constitution, statute or rule of law or by the enforcement of 
any assessment or penalty or otherwise, all such liability being, by the 
acceptance hereof and as part of the consideration for the issue hereof, 
expressly waived and released.
