     Re:  Agreement of Purchase and Sale dated as of April 15, 1998, as
          amended (the "Agreement"), by and among JJ Acquisition Corp. (now
          Jeri-Jo Knitwear, Inc.), Norton McNaughton, Inc. (now McNaughton
          Apparel Group Inc.), Jeri-Jo Knitwear Inc., Jamie Scott, Inc. and the
          Stockholders of Jamie Scott, Inc.

Ladies and Gentlemen:

          Reference is made to the Agreement.  Capitalized terms used and not
defined below shall have the meanings assigned to such terms in the Agreement.
For good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto hereby amend the Agreement as set forth
below.

     (d) as follows:

          "(d)  Notwithstanding anything to the contrary contained herein,
          including without limitation the definition of "Earn Out Payment"
          contained herein, the Earn Out Payment otherwise payable hereunder
          shall be payable by the Purchaser and Norton as follows:

          (A)(i) At or before 3:00 p.m. on August 29, 2000 (time being of the
                 essence):

                (1)   the Purchaser and Norton shall pay $95,000,000 (the
                      "Initial Payment") to the Designees by wire transfer of
                      immediately available funds to a bank account(s)
                      designated by the Designees;

                (2)   Norton shall issue the Earn Out Payment Shares (as defined
                      below) and deliver to the Designees a certificate(s)
                      representing the Earn Out Payment Shares, which
                      certificate(s) shall not contain any legends under the
                      Securities Act of 1933, as amended, or other legends and

                      of the transactions contemplated hereby;
<PAGE>

                (3)    Norton shall issue and deliver the Note (as defined
                       below) to the Designees;

                (4)    Norton shall deliver to the Designees the documents
                       (except in respect of Section 5.03 as to agreements to
                       which Norton or the Purchaser are a party), in form and
                       substance reasonably satisfactory to counsel to the
                       Designees, which satisfy the Bring Down Obligation; and

                (5)(i) Section 7.14 shall terminate and be of no further force
                       and effect, (ii) the representations and warranties made
                       in this Agreement (except in Section 3.28, it being
                       agreed that clause (v) of Section 3.28 is to be read in
                       light of Section 7(ii) hereof) shall expire
                       (notwithstanding the provisions of Section 11.06(d)
                       hereof) and (iii) the options to purchase shares of
                       Norton Common Stock granted pursuant to Section 3.3 of
                       each of the Employment Agreements shall vest in full.

     (ii) As a condition to the Purchaser's and Norton's obligations under
     clause (A)(i) above, simultaneously with the delivery of the items set
     forth in clauses (A)(i)(1) through (A)(i)(4) above, the Stockholder
     Representative shall deliver the Earn Out Letter of Credit to Norton for
     cancellation.

     (B)(i) In the event that the last closing (the "New Financing Closing") of
     the New Financing shall occur on or before November 30, 2000, then the
     parties hereto agree that, notwithstanding the dispute provisions of
     Section 2.02(b)(iii) hereof (which shall have no force or effect), the Earn
     Out Payment shall be discounted and shall be fully satisfied by the payment
     (without claim or offset by Norton or the Purchaser) to the Designees of an
     aggregate of (i) $125,000,000 in cash (the "Cash Payment"), consisting of
     the Initial Payment payable as set forth in subsection (A)(i)(1) above and
     the balance of the Cash Payment payable as set forth in subsection (B)(ii)
     below, (ii) the issuance of 2,000,000 shares (valued at $13.00 per share)
     (the "Earn Out Payment Shares") of Norton Common Stock as set forth in
     subsection (A)(i)(2) above and (iii) the issuance by Norton of its
     unsecured subordinated note(s) (collectively, the "Note") as set forth in
     subsection (A)(i)(3) above containing the terms and conditions set forth in
     subsection (B)(iii) below.

     (ii) In the circumstances set forth in subsection (B)(i) above, on the date
     of the New Financing Closing the Purchaser and Norton shall pay to the
     Designees by wire transfer in immediately available funds to a bank
     account(s) designated by the Designees the remaining $30,000,000 of the
     Cash Payment.

     (iii)  The Note shall contain the following terms:

            (1)  the Note shall be in the aggregate principal amount of
                 $10,000,000;

            (2)  the Note shall have the following scheduled payments: (i) in an
                 amount equal to the lesser of the principal amount then
                 outstanding and the Excess Proceeds (as defined below) on the
                 date of the closing of an Underwritten Offering (as defined
                 below), (ii) $2,500,000 (or such lesser amount as shall at the
                 time be outstanding) on the first Business Day of each of
                 Norton's fiscal quarters following the payment in full of all
                 overadvances/term loans and (iii) in full on November 30, 2003;

            (3)  interest on the outstanding principal amount of the Note shall
                 be payable monthly in arrears at the same rate per annum in
                 effect from time to time as the rate payable on non-overadvance
                 revolving credit borrowings under the New Financing;

            (4)  the amounts owing under the Note shall be unsecured and shall
                 be subordinated to all of the amounts (including "post petition
                 interest") owing under (A) the Amended and Restated Financing
                 Agreement dated as of June 18, 1998, as heretofore amended and
                 as further amended from time to time, among Norton, the
                 Purchaser,
<PAGE>

                 Nationsbanc Commercial Corporation, The CIT Group/Commercial
                 Services, Inc., Fleet Bank NA and others, (B) any financing
                 agreement(s) relating to the New Financing (other than equity
                 financing) and (C) the Indenture (the "Indenture") dated as of
                 June 18, 1998, as heretofore supplemented and as further
                 supplemented from time to time, among Norton, the Subsidiary
                 Guarantors named in that Indenture and United States Trust
                 Company of New York as trustee (the items referred to in
                 clauses (A), (B) and (C) above, collectively the "Senior
                 Indebtedness"); such subordination to be on normal and
                 customary terms and conditions reasonably acceptable to the
                 parties hereto and to the holders of the Senior Indebtedness,
                 which shall include nonpayment on the Note during the
                 continuance of an event of default under any of the Senior
                 Indebtedness, but which shall permit interest on the Note to be
                 paid currently in cash other than during the continuance of an
                 event of default under any of the Senior Indebtedness (the
                 foregoing, collectively, the "Subordination");

            (5)  Norton may make prepayments on the Note without premium or
                 penalty at anytime and from time to time, such prepayments to
                 be applied first to the amount of accrued and unpaid interest
                 thereon through the date of such prepayment and second to
                 outstanding principal amount of the Note;

            (6)  in the event that Norton consummates an underwritten public
                 offering of Norton Common Stock while amounts under the Note
                 are outstanding (an "Underwritten Offering"), the proceeds from
                 that offering, after payment of all underwriting commissions
                 and discounts and all expenses of the offering and after the
                 payment in full of all overadvances/term loans under the New
                 Financing (the "Excess Proceeds"), shall be paid by Norton to
                 the Designees as a scheduled payment on the Note (to the extent
                 of amounts owing thereunder), which scheduled payment shall be
                 applied first to the amount of accrued and unpaid interest
                 thereon through the date of such prepayment and second to
                 outstanding principal of the Note; as used herein
                 "overadvances/term loans" shall mean the principal portion of
                 the New Financing which are term loans and/or which are in
                 excess of 85% of the eligible accounts receivable and 60% of
                 the eligible inventory of Norton and its subsidiaries;

            (7)  in the event that all overadvances/term loans under the New
                 Financing have been repaid in full, including pursuant to
                 clause (6) above, Norton shall make scheduled payments of
                 $2,500,000 on the Note, in the aggregate, or such lesser amount
                 as may be owing under the Note, on the first Business Day of
                 each of Norton's fiscal quarters following the date on which
                 the overadvances/term loans were repaid in full, until all
                 principal owing under the Note has been repaid in full;

            (8)  each Designee may declare the entire amount under the Note held
                 by such person due and owing after the occurrence and during
                 the continuance of an Event of Default (as defined below) under
                 the Note and, following such declaration (and as the Designees'
                 sole and exclusive remedy), at the election of such Designee
                 given within 15 Business Days after the occurrence of such
                 Event of Default (A) Norton shall issue a fraction of a share
                 of Norton Common Stock to the Designees for each dollar in
                 outstanding principal amount in default equal to one (1)
                 divided by the Market Price Factor and, in such case, the Note
                 shall be deemed paid in full; provided that in no event shall
                 the aggregate number of shares of Norton Common Stock issued to
                 a Designee exceed such Designee's Percentage Interest
                 multiplied by 2,230,000 shares of Norton Common Stock or (B)
                 the Note shall remain outstanding and due and payable, subject
                 to the Subordination, and no shares of Norton Common
<PAGE>

                 Stock shall be issued by Norton to the Designees (it being
                 understood and agreed to by the parties hereto that the failure
                 by any Designee so to deliver such election in a timely manner
                 shall terminate the right of such Designee to make such
                 election and shall grant Norton the right to make such election
                 on behalf of such Designee); the events of default (the "Events
                 of Default") under the Note shall be (a) subject to the terms
                 of the Subordination, failure by Norton to pay the principal of
                 or interest on the Note within five (5) Business Days' after
                 the due date therefor, (b) bankruptcy and insolvency events
                 relating to Norton and its subsidiaries (subject to normal
                 dismissal periods), (c) acceleration of any of the Senior
                 Indebtedness and (d) in a single or series of related
                 transactions, the sale of all or substantially all of the
                 assets of Norton or the sale by the holders thereof (whether by
                 merger or otherwise) of a majority of the voting capital stock
                 of Norton (determined on a fully diluted basis); Norton agrees
                 to notify the Designees of the occurrence of an Event of
                 Default; and

            (9)  the Note shall not contain any covenants of Norton other than
                 as set forth above and other than normal and customary
                 affirmative covenants covering compliance with laws,
                 preservation of existence, maintenance of books and records,
                 and maintenance of insurance.

     (C)(i)  In the event that the New Financing Closing shall not have occurred
     on or before November 30, 2000, then the parties hereto agree that,
     notwithstanding the dispute provisions of Section 2.02(b)(iii) hereof
     (which shall have no force or effect), the Earn Out Payment shall be
     discounted and shall be fully satisfied by the payment (without claim or
     offset by Norton or the Purchaser) to the Designees of an aggregate of (i)
     the Initial Payment as set forth by subsection (A)(i)(1) above, (ii) the
     Earn Out Payment Shares as set forth by subsection (A)(i)(2) above, (iii)
     the Note as set forth by subsection (A)(i)(3) above and (iv) on December 1,
     2000, $59,000,000 (the "Final Payment") in the manner set forth in
     subsection (C)(ii) below.

       (ii) The Final Payment shall be made by Norton to the Designees based
     upon their Percentage Interest and, at the election of Norton, in cash,
     shares of Norton Common Stock (the "Second Shares") and/or unsecured
     subordinated note(s) of Norton (collectively, the "Second Note") (with each
     Second Note to contain the same terms and conditions as the Note, except
     the principal amount thereof, except that the proviso contained in
     subsection (d)(B)(iii)(8)(A) shall not be applicable and except that the
     payment of the Note and the Second Note with Excess Proceeds shall be made
     on a pro-rata basis).  In connection with the payment of the Final Payment,
     each of the Second Shares shall be valued at the Market Price Factor
     determined as of the close of business on November 27, 2000.  It is
     understood and agreed by the parties hereto that the aggregate amount of
     the Final Payment shall be reduced by $1.967 for every $1.00 in cash paid
     by the Purchaser and Norton to the Designees after August 29, 2000 and in
     payment of the remaining $59,000,000 balance of the Earn Out Payment in the
     circumstances contemplated by this subsection (C).

       (iii)  Under the circumstances set forth in this subsection (C), Norton
     and the Purchaser hereby agree to reasonably cooperate with the Designees
     in connection with any filings required under the Hart-Scott-Rodino
     Antitrust Improvement Act of 1976 or under other statutes or regulatory
     provisions, and in the event that any such filings are required, the
     parties hereto understand and agree that any time periods set forth in this
     subsection (C) shall be extended in order to accommodate all applicable
     waiting periods and other filing requirements under such statutes and
     regulatory provisions.

       (iv) In connection with the issuance of Second Shares under this
     subsection (C), (a) the certificates representing such Second Shares shall
     not contain any legends under the Securities Act of 1933, as
<PAGE>

     amended, or other legends and shall not be subject to any stop order issued
     by Norton's transfer agent arising out of the transactions contemplated
     hereby and (b) Norton shall deliver to the Designees the documents (except
     in respect of Section 5.03 as to agreements to which Norton or the
     Purchaser are a party), in form and substance reasonably satisfactory to
     counsel to the Designees, which satisfy the Bring Down Obligation.

2.  Sections 2.04(a), (b) and (c) of the Agreement (other than relevant
definitions contained therein which are later used in the Agreement, except that
the term "Holder" is hereby amended to mean each of the several Designees) are
deleted and replaced with "Intentionally Deleted".

3.  Section 2.04(f) is amended by adding the following at the end thereof:

     "The Designees and Norton agree that, for the purpose of determining the
     reduction and allocation of Supplemental Registration Shares pursuant to
     this subsection (f) and the reduction and allocation of shares of Norton
     Common Stock otherwise to be included in the subject registration statement
     and beneficially owned by Sanford Greenberg, Jay Greenberg, Norton
     Sperling, Stuart Bregman, Howard Zwilling and the other sellers of the Miss
     Erika business (all being other persons holding "piggyback" registration
     rights in respect of Norton Common Stock) (the "Other Rights Persons"),
     such reduction and allocation shall occur pro-rata among Supplemental
     Registration Investors and Other Rights Persons and on a basis which takes
     into account shares of Norton Common Stock issuable pursuant to then
     currently exercisable options held by Supplemental Registration Investors
     and Other Rights Persons."

4.  Section 2.04(g) of the Agreement is amended by deleting clauses (i) and (ii)
thereof and replacing such clauses with "Intentionally Deleted".

5.  Section 14.01 of the Agreement is amended by adding the following
definitions as follows:

          "Designees" shall mean each of Leonard Schneider, Susan Schneider,
          Leslie Schneider and Scott Schneider (it being agreed that all
          references to "Designees" herein shall mean each of such persons on a
          several basis).

          "Market Price Factor" shall mean the lower of (i) $13.00 (as such
          number shall be adjusted for stock splits, stock dividends and similar
          events) and (ii) the Market Value (determined on the basis of a 20-
          Business Day average) of a share of Norton Common Stock on the date of
          the occurrence of an event of default under the Note and/or the Second
          Note (in the case of Section 2.02(d)(B)(iii)(8)(A)), or on November
          27, 2000 (in the case of Section 2.02(d)(C)(ii)).

          "New Financing" shall mean bank and/or other debt or equity financing
          arrangements to be entered into, if at all, by Norton and/or its
          subsidiaries in amounts and on terms and conditions (acceptable to
          Norton in its sole discretion) which enable the Purchaser and Norton
          to make the Earn Out Payment in the amount and in the manner described
          in Section 2.02(d)(B)(i) hereof.

6.  The parties hereto understand and agree that whenever herein the Purchaser
and/or Norton are required to deliver the Cash Payment (including the Initial
Payment), the Earn Out Payment Shares, the Note and/or the Final Payment (if
applicable) to the Designees in respect of the separate acquisitions by the
Purchaser of each of the Companies, the Purchaser and/or Norton, as applicable,
shall deliver the Designees' applicable Percentage Interest of the Cash Payment
(including the Initial Payment), the Earn Out Payment Shares, the Note and/or
the Final Payment (if applicable) to Leonard Schneider (the sole shareholder of
Jeri-Jo Knitwear, Inc.), and to Susan Schneider, Leslie Schneider and Scott
Schneider (as the shareholders of Jamie Scott, Inc.), respectively.
<PAGE>

7.  The Stockholders represent and warrant to Norton and the Purchaser that JJK
II, Inc. (formerly known as Jeri-Jo Knitwear, Inc.) and JJK III, Inc. (formerly
known as Jamie Scott, Inc.), heretofore parties to the Agreement, have been
liquidated and are no longer in existence.  Accordingly, the Stockholders agree
that the execution of this amendment by the Companies is not necessary.  In
addition, the Designees agree with Norton and the Purchaser that neither they
nor any of their affiliates or immediate family members shall publicly sell or
otherwise publicly transfer any shares of Norton Common Stock until the earlier
to occur of the New Financing Closing or November 30, 2000 (it being understood
and agreed by the Designees that notwithstanding anything to the contrary
contained herein, Norton may instruct its transfer agent to issue appropriate
stop orders in order to give effect to the foregoing agreement by the
Designees).

8.  Norton represents and warrants to the Designees that the Board of Directors
of Norton has waived the applicability of its Stockholders Rights Plan (the
"Plan") in respect of the Designees' ownership of Norton Common Stock as a
result of the consummation of the transactions contemplated by the Agreement and
the Employment Agreements, by resolving to amend the Plan to permit the
issuances of Norton Common Stock contemplated under the Agreement and the
Employment Agreements without causing the Plan to become effective with respect
to the Designees and the shares of Norton Common Stock issuable hereunder and
thereunder and issuable pursuant to options to acquire Norton Common Stock held
by the Designees.  Norton agrees to use its commercially reasonable efforts to
effect the New Financing.

9.  Except as amended by this amendment, the Agreement is ratified and confirmed
in all respects.  Nothing in this amendment shall confer or be deemed to confer
any right, remedy, benefit or entitlement on any third party (other than the
Designees).  This amendment shall be construed pursuant to and in accordance
with the laws of the State of New York, without regard to conflict of law
principles, and may be executed in counterparts, including by telecopy, each of

one and the same amendment.

10.  Notwithstanding anything to the contrary contained herein, in the event
that the Purchaser and Norton default under the provisions of Section
2.02(d)(A)(i) of the Agreement, (i) this amendment shall terminate (except the

that may occur as and when due), (C) in the event of any non-payment of such
amount as and when due the beneficiary under that certain Letter of Credit No.

Credit), and (D) such non-payment would be properly described by checking the
second certification box (respecting the "Second Amount") in submitting a
drawing Certificate substantially in the same form as Exhibit B annexed to such
Earn Out Letter of Credit.

<PAGE>

                                   ARTICLE 1

                             CREATION OF THE NOTES

     1.1  DESIGNATION OF SERIES.

     Pursuant to the terms hereof and Section 301 of the Indenture, the Company
hereby creates a series of Securities designated as the "3.25% Convertible

     The Notes shall not exceed U.S. $402,500,000 in aggregate principal amount,
and may, upon the execution and delivery of this First Supplemental Indenture or
from time to time thereafter, be executed by the Company and delivered to the

and Opinion of Counsel as contemplated by Section 303 of the Indenture.

     1.4  INTEREST.

     The Notes shall bear interest at a rate of 3.25% per annum, payable semi-
annually.  The Interest Payment Dates for the Notes shall be February  15 and
August 15 of each year, commencing February 15, 2001, with interest payable in
Dollars to Holders in whose names the Notes are registered at the close of
business on February 1 or August 1 of each year (each, a "Record Date"), or, if
such Record Date is not a Business Day, at the close of business of the
immediately succeeding Business Day.

     1.5  CERTIFICATE OF AUTHENTICATION.

     The Trustee's certificate of authentication to be borne on the Notes shall

     1.8  DISCHARGE OF INDENTURE; DEFEASANCE.

     The Notes shall not be subject to the provisions of Article XIII of the
Indenture.

     1.9  OTHER TERMS OF NOTES.

     The other terms of the Notes shall be as expressly set forth in Articles 2,
3, 4, 5, 6 and 7 hereof and Exhibit A hereto.

     The words "herein", "hereof" and "hereunder" and other words of similar
import refer to this First Supplemental Indenture as a whole and not to any
particular Article, Section or other subdivision.

                                   ARTICLE 2

                              CONVERSION OF NOTES

     2.1  CONVERSION PRIVILEGE.

     Subject to and upon compliance with the provisions of this Article 2, at
the option of the Holder thereof, any Note or any portion of the principal
amount thereof which is $1,000 or an integral multiple of $1,000, and which has
not previously been redeemed pursuant to Article 3 hereof or repurchased
pursuant to Article 4 hereof, may be converted into fully paid and nonassessable
shares of common stock of the Company, $0.01 par value per share (the "Common
Stock"), at the conversion rate, determined as hereinafter provided, in effect
at the time of conversion.  Such conversion right shall commence on the date of
original issuance of the Notes, and shall expire at the close of business on the
Business Day immediately preceding the  Stated Maturity.  In case a Note or
portion thereof is called for redemption, such conversion right in respect of
the Note or portion so called shall expire at the close of business on the
Business Day immediately preceding the Redemption Date, unless the Company
defaults in making the payment due upon redemption.  A Note in respect of which
a Holder has delivered a Repurchase Notice pursuant to Section 4.1 hereof may be
converted only if such Repurchase Notice is withdrawn in accordance with the
terms of such section, unless the Company defaults in the payment of the Change
of Control Repurchase Price.

     2.2  CONVERSION RATE.

     The rate at which shares of Common Stock shall be delivered upon conversion
(the "Conversion Rate") shall be initially 7.2446 shares of Common Stock for
each $1,000 principal amount of Notes.  The Conversion Rate shall be adjusted in
certain instances as provided in Section 2.5 hereof.  All calculations under
this Article 2 shall be made to the nearest cent or the nearest 1/100th of a
share, as the case may be.

                                       3
<PAGE>

     2.3  EXERCISE OF CONVERSION PRIVILEGE.

     In order to exercise the conversion privilege, the Holder of any Note to be
converted shall surrender such Note, duly endorsed or assigned to the Company or
in blank, at the Corporate Trust Office of the Trustee, located at 14 Wall
Street, 8th Floor, New York, New York 10005, Attn:  Corporate Trust
Administration, accompanied by a duly signed and completed written notice to the
Company at the Corporate Trust Office that the Holder elects to convert such
Note. Holders of Notes surrendered for conversion during the period from the
close of business on any Record Date immediately preceding any Interest Payment
Date to the opening of business on such Interest Payment Date shall (except in
the case of Notes or portions thereof which have been called for redemption or
in respect of which the Repurchase Notice delivered by the Holder has not been
withdrawn, the conversion rights of which would terminate during the period
between such Record Date and the close of business on such Interest Payment
Date) be entitled to receive the interest payable on such Interest Payment Date
on the principal amount of Notes being surrendered for conversion.  Such Notes
surrendered for conversion during the period from the close of business on any
Record Date immediately preceding any Interest Payment Date to the opening of
business on such Interest Payment Date shall (except in the case of Notes or
portions thereof which have been called for redemption or in respect of which
the Repurchase Notice delivered by the Holder has not been withdrawn, the
conversion rights of which would terminate during the period between such Record
Date and the close of business on such Interest Payment Date) be accompanied by
payment in immediately available funds or other funds acceptable to the Company
of an amount equal to the interest payable on such Interest Payment Date on the
principal amount of Notes being surrendered for conversion.  Except as set forth
above, no payment or adjustment shall be made upon any conversion on account of
any interest accrued on the Notes surrendered for conversion from the Interest
Payment Date preceding the day of conversion, or on account of any dividends on
the Common Stock issued upon conversion.  In addition, Holders shall not be
entitled to receive any dividends payable to holders of Common Stock as of any
record date before the close of business on the conversion date.  Notes shall be
deemed to have been converted immediately prior to the close of business on the
day of surrender of such Notes for conversion in accordance with the foregoing
provisions, and at such time the rights of the Holders of such Notes as Holders
shall cease, and the Person or Persons entitled to receive the Common Stock
issuable upon conversion shall be treated for all purposes as the record holder
or holders of such Common Stock at such time.  As promptly as practicable on or
after the conversion date, the Company shall issue and shall deliver to the
Trustee at its Corporate Trust Office a certificate or certificates for the
number of full shares of Common Stock issuable upon conversion, together with
payment in lieu of any fraction of a share thereof, as provided in Section 2.4
hereof, and the Trustee shall forward such certificate or certificates at the
addresses set forth in the written notices sent to the Company by the Holders
electing to convert their Notes.

     2.4  FRACTIONS OF COMMON STOCK SHARES.

     No fractional shares of Common Stock shall be issued upon conversion of the
Notes.  If more than one Note shall be surrendered for conversion at one time by
the same Holder, the number of full shares which shall be issuable upon
conversion thereof shall be computed on the basis of the aggregate principal
amount of the Notes so surrendered.  Instead of any fractional share of Common
Stock which would otherwise be issuable upon conversion of any Note or

                                       4
<PAGE>

Notes, the Company shall pay a cash adjustment in respect of such fraction in an
amount equal to the same fraction of the Market Price (determined by the Company
in accordance with the following paragraph) per share of Common Stock.

     For purposes of this Section 2.4, "Market Price" means the Sale Price (as
defined below) of the Common Stock on the date of conversion of the Notes or, if
such date is not a Trading Day (as defined below), then on the last Trading Day
prior to such date.  The "Sale Price" of the Common Stock on any date means the
closing per share sale price (or if no closing sale price is reported, the
average of the bid and ask prices or, if more than one in either case, the
average of the average bid and average ask prices) on such date as reported in
the composite transactions for the principal United States securities exchange
on which the Common Stock is traded or, if the Common Stock is not listed on a
United States national or regional stock exchange, as reported by the Nasdaq
National Market.  "Trading Day" means, in respect of any securities exchange or
securities market, each Monday, Tuesday, Wednesday, Thursday and Friday, other
than any day on which securities are not traded on the applicable securities
exchange or in the applicable securities market.

     2.5  ADJUSTMENT OF CONVERSION RATE.

     (1)  In case at any time after the date of the issuance of the Notes, the
Company shall pay or make a dividend or other distribution to the Common Stock
payable in shares of its Common Stock, the Conversion Rate in effect at the
opening of business on the day following the date fixed for the determination of
stockholders entitled to receive such dividend or other distribution shall be
increased by dividing such Conversion Rate by a fraction of which the numerator
shall be the number of shares of Common Stock outstanding at the close of
business on the date fixed for such determination and the denominator shall be
the sum of such number of shares and the total number of shares constituting
such dividend or other distribution, such increase to become effective
immediately after the opening of business on the day following the date fixed
for such determination. For the purposes of this paragraph (1), the number of
shares of Common Stock at any time outstanding shall not include shares held in
the treasury of the Company but shall include shares issuable in respect of
scrip certificates issued in lieu of fractions of shares of Common Stock. The
Company will not pay any dividend or make any distribution on shares of Common
Stock held in the treasury of the Company.

     (2)  Subject to paragraph (9) of this Section 2.5, in case at any time
after the date of the issuance of the Notes, the Company shall issue rights,
options or warrants to all holders of its Common Stock (other than any rights,
options or warrants that by their terms will also be issued to any Holder upon
conversion of a Note into Common Stock without any action required by the
Company or any other Person) entitling them to subscribe for or purchase shares
of Common Stock at a price per share less than the then current market price per
share (determined as provided in paragraph (9) of this Section 2.5) of the
Common Stock on the date fixed for the determination of stockholders entitled to
receive such rights, options or warrants (other than pursuant to a dividend
reinvestment plan), the Conversion Rate in effect at the opening of business on
the day following the date fixed for such determination shall be increased by
dividing such Conversion Rate by a fraction of which the numerator shall be the
number of shares of Common Stock outstanding at the close of business on the
date fixed for such determination plus the number of shares of Common Stock
which the aggregate of the offering

                                       5
<PAGE>

price of the total number of shares of Common Stock so offered for subscription
or purchase would purchase at the then current market price and the denominator
shall be the number of shares of Common Stock outstanding at the close of
business on the date fixed for such determination plus the number of shares of
Common Stock so offered for subscription or purchase, such increase to become
effective immediately after the opening of business on the day following the
date fixed for such determination. For the purposes of this paragraph (2), the
number of shares of Common Stock at any time outstanding shall not include
shares held in the treasury of the Company but shall include shares issuable in
respect of scrip certificates issued in lieu of fractions of shares of Common
Stock. The Company will not issue any rights, options or warrants in respect of
shares of Common Stock held in the treasury of the Company.

     (3)  In case at any time after the date of the issuance of the Notes,
outstanding shares of Common Stock shall be subdivided into a greater number of
shares of Common Stock, the Conversion Rate in effect at the opening of business
on the day following the day upon which such subdivision becomes effective shall
be proportionately increased, and, conversely, in case outstanding shares of
Common Stock shall be combined into a smaller number of shares of Common Stock,
the Conversion Rate in effect at the opening of business on the day following
the day upon which such combination becomes effective shall be proportionately
reduced, such reduction or increase, as the case may be, to become effective
immediately after the opening of business on the day following the day upon
which such subdivision or combination becomes effective.

     (4)  In case at any time after the date of the issuance of the Notes, the
Company shall, by dividend or otherwise, distribute to all holders of its Common
Stock, shares of any class of its capital stock, evidences of its indebtedness
or other assets (including securities, but excluding any rights, options or
warrants referred to in paragraph (2) of this Section 2.5, any dividend or
distribution paid exclusively in cash, any dividend or distribution referred to
in paragraph (1) of this Section 2.5 and distributions upon a merger or
consolidation to which Section 2.12 applies), the Conversion Rate shall be
adjusted so that the same shall equal the rate determined by dividing the
Conversion Rate in effect immediately prior to the close of business on the date
fixed for the determination of stockholders entitled to receive such
distribution by a fraction of which the numerator shall be the current market
price per share (determined as provided in paragraph (9) of this Section 2.5) of
the Common Stock on the date fixed for such determination less the then fair
market value (as determined by the Board of Directors, whose determination shall
be conclusive and described in a Board Resolution filed with the Trustee) of the
portion of the assets, shares of capital stock or evidences of indebtedness so
distributed applicable to one share of Common Stock and the denominator shall be
such current market price per share of the Common Stock, such adjustment to
become effective immediately prior to the opening of business on the day
following the date fixed for the determination of stockholders entitled to
receive such distribution. If the Board of Directors determines the fair market
value of any distribution for purposes of this paragraph (4) by reference to the
actual or when issued trading market for any securities comprising such
distribution, it must in doing so consider the prices in such market over the
same period used in computing the current market price per share pursuant to
paragraph (9) of this Section 2.5.

     (5)  In case at any time after the date of the issuance of the Notes, the
Company shall, by dividend or otherwise, distribute to all holders of its Common
Stock cash (excluding any cash

                                       6
<PAGE>

that is distributed upon a merger or consolidation to which Section 2.12 applies
or as part of a distribution referred to in paragraph (4) of this Section 2.5)
in an aggregate amount that, combined together with:

          (A)  the aggregate amount of any other 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 paragraph (5) has been made, and

          (B)  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 filed with the Trustee) 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 paragraph (6) of this Section
     2.5 has been made,

(the amount of such cash distribution together with the amounts described in
clauses (A) and (B) above being referred to herein as the "Aggregate Cash
Distribution Amount") exceeds 10% of the product of (I) the current market price
per share (determined as provided in paragraph (9) of this Section 2.5) of the
Common Stock on the date for the determination of holders of shares of Common
Stock entitled to receive such distribution, times (II) the number of shares of
Common Stock outstanding on such date (the amount by which the Aggregate Cash
Distribution Amount exceeds 10% of the product of the amounts described in
clauses (I) and (II) above being referred to herein as the "Excess Amount"),
then, and in each such case, immediately after the close of business on such
date for determination, the Conversion Rate shall be increased in accordance
with the following formula:

                             AC = CR/  M - (EA/O)
                                      ------------
                                           M
Where:

AC = the adjusted Conversion Rate.

CR = the Conversion Rate in effect immediately prior to the close of business on
the date fixed for determination of the stockholders entitled to receive the
distribution.

M = the current market price per share (determined as provided in paragraph (9)
of this Section 2.5) of the Common Stock on the date fixed for determination of
the stockholders entitled to receive the distribution.

EA = the Excess Amount.

O = the number of shares of Common Stock outstanding on the date fixed for
determination of the stockholders entitled to receive the distribution.

     (6)  In case at any time after the date of the issuance of the Notes, a
tender offer made by the Company or any Subsidiary for all or any portion of the
Common Stock shall expire and such tender offer (as it may be amended) 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 filed with the Trustee) that combined together with:

          (A)  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 filed with the Trustee), as
     of the expiration of such tender offer, of consideration payable in respect
     of any other tender offer, by the Company or any Subsidiary 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 this paragraph (6) has been made, and

          (B)  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 paragraph (5) of this Section 2.5 has been made, exceeds 10% of
     the product of (I) the current market price per share (determined as
     provided in paragraph (9) of this Section 2.5) of the Common Stock as of
     the last time (the "Expiration Time") tenders could have been made pursuant
     to such tender offer (as it may be amended), times (II) the number of
     shares of Common Stock outstanding (including any tendered shares) on the
     Expiration Time, 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 Rate shall be reduced in accordance with the following formula:

                             AC = CR/ (M x O) - C
                                      ------------
                                      M x (O - TS)

Where:

AC = the adjusted Conversion Rate.

CR = the Conversion Rate immediately prior to close of business on the date of
the Expiration Time.

M = the current market price per share (determined as provided in paragraph (9)
of this Section 2.5) of the Common Stock on the date of the Expiration Time.

O = the number of shares of Common Stock outstanding (including any tendered
shares) on the Expiration Time.

C = the amount of cash plus the fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution filed with the Trustee) of the aggregate consideration payable to
stockholders based on the acceptance (up to any maximum specified in the terms
of the tender offer) of Purchased Shares (as defined below).

TS = the number 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").

                                       8
<PAGE>

     (7)  The reclassification of Common Stock into securities other than Common
Stock (other than any reclassification upon a consolidation or merger to which
Section 2.12 applies) shall be deemed to involve (a) a distribution of such
securities other than Common Stock to all holders of Common Stock (and the
effective date of such reclassification shall be deemed to be "the date fixed
for the determination of stockholders entitled to receive such distribution" and
"the date fixed for such determination" within the meaning of paragraph (4) of
this Section 2.5), and (b) a subdivision or combination, as the case may be, of
the number of shares of Common Stock outstanding immediately prior to such
reclassification into the number of shares of Common Stock outstanding
immediately thereafter (and the effective date of such reclassification shall be
deemed to be "the day upon which such subdivision becomes effective" or "the day
upon which such combination becomes effective", as the case may be, and "the day
upon which such subdivision or combination becomes effective" within the meaning
of paragraph (3) of this Section 2.5).

     (8)  In case at any time after the date of the issuance of the Notes, the
Company shall issue rights or warrants to all holders of the Common Stock
entitling the holders thereof to subscribe for or purchase shares of Common
Stock (either initially or under certain circumstances), which rights or
warrants (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, in each case in clauses (i) through (iii) until the occurrence of
a specified event or events ("Trigger Event"), such rights or warrants shall for
purposes of this Section 2.5 not be deemed issued or distributed until the
occurrence of the earliest Trigger Event, whereupon such rights and warrants
shall be deemed to have been distributed and an appropriate adjustment (if any
is required) to the Conversion Rate shall be made under this Section 2.5. If any
such rights or warrants, including any such existing rights or warrants
distributed prior to the date of this Indenture are subject to subsequent
events, upon the occurrence of each of which such rights or warrants shall
become exercisable to purchase different securities, evidences of indebtedness
or other assets, then the occurrence of each such event shall be deemed to be
such date of issuance and record date with respect to new rights or warrants
(and a termination or expiration of the existing rights or warrants without
exercise by the holder thereof). In addition, in the event of any distribution
(or deemed distribution) of rights or warrants, or any Trigger Event with
respect thereto, that was counted for purposes of calculating a distribution
amount for which an adjustment to the Conversion Rate under this Section 2.5 was
made, (1) in the case of any such rights or warrant which shall all have been
redeemed or repurchased without exercise by any holders thereof, the Conversion
Rate 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 or holders of Common Stock with respect to such rights or
warrants (assuming such holder had retained such rights 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 or warrants which shall have expired or been
terminated without exercise by any holders thereof, the Conversion Rate shall be
readjusted as if such rights and warrants had not been issued.

     (9)  For the purpose of any computation under paragraphs (2), (4), (5) or
(6) of this Section 2.5, the current market price per share of Common Stock on
any date shall be deemed to be the average of the daily Sale Prices (as defined
in Section 2.4 hereof) of the Common Stock for the five consecutive Trading Days
(as defined in Section 2.4 hereof) selected by the Company commencing not more
than ten Trading Days before, and ending not later than the earlier of, the day
in question and the day before the "ex" date with respect to the issuance or
distribution requiring such computation. For purposes of this paragraph, the
term "ex" date, when used with respect to any issuance or distribution, means
the first date on which the Common Stock trades regular way in the applicable
securities market or on the applicable securities exchange without the right to
receive such issuance or distribution.

     (10) No adjustment in the Conversion Rate shall be required unless such
adjustment (plus any adjustments not previously made by reason of this paragraph
(10)) would require an increase or decrease of at least 1.0% in such rate;
provided, however, that any adjustments which by reason of this paragraph (10)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this paragraph (10) shall be
made to the nearest whole cent.

     (11) The Company may make such increases in the Conversion Rate, in
addition to those required by this Section 2.5, as it considers to be advisable
in order to avoid or diminish any income tax to any holders of shares of Common
Stock resulting from any dividend or distribution of stock or issuance of rights
or warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes or for any other reasons. The Company shall have the
power to resolve any ambiguity or correct any error in this paragraph (11) and
its decisions in so doing shall be final and conclusive.

     (12) To the extent permitted by applicable law, the Company from time to
time may increase the Conversion Rate by any amount for any period of time if
the period is at least 20 days, the increase is irrevocable during such period,
and the Board of Directors shall have made a determination that such increase
would be in the best interests of the Company, which determination shall be
conclusive. Whenever the Conversion Rate is increased pursuant to the preceding
sentence, the Company shall give notice of the increase to the Holders in the
manner provided for in Section 105 of the Indenture at least 15 days prior to
the date the increased Conversion Rate takes effect, and such notice shall state
the increased Conversion Rate and the period during which it will be in effect.

     (13) In the event that this Article 2 requires adjustments to the
Conversion Rate under more than one of Sections 2.5(1), 2.5(2), 2.5(4) or 2.5(5)
hereof, and the record dates for the distributions giving rise to such
adjustments shall occur on the same date, then such adjustments shall be made by
applying, first, the provisions of Section 2.5(4), second, the provisions of
Section 2.5(5), third, the provisions of Section 2.5(1) and, fourth, the
provisions of Section 2.5(2). After an adjustment to the Conversion Rate under
this Article 2, any subsequent event requiring an adjustment under this Article
2 shall cause an adjustment to the Conversion Rate as so adjusted. Whenever
successive adjustments to the Conversion Rate are called for pursuant to this
Article 2, such adjustments shall be made to the provisions of Section 2.5(9)
hereof as may be necessary or appropriate to effectuate the intent of this
Article 2 and to avoid unjust or inequitable results as determined in good faith
by the Board of Directors.

     2.6  NOTICE OF ADJUSTMENTS OF CONVERSION RATE.

     Whenever the Conversion Rate is adjusted as herein provided: (a) the
Company shall compute the adjusted Conversion Rate in accordance with Section
2.5 hereof and shall prepare an Officers' Certificate, one of the signatories of
which shall be the Treasurer or Chief Financial Officer of the Company, setting
forth the adjusted Conversion Rate (certified by the Company's independent
public accountants or other certified public accountant) and showing in
reasonable detail the facts upon which such adjustment is based, and such
certificate shall forthwith be filed with the Trustee at each office or agency
maintained for the purpose of conversion of Securities pursuant to Section 2.3
hereof; and (b) a notice stating that the Conversion Rate has been adjusted and
setting forth the adjusted Conversion Rate shall forthwith be required, and as
soon as practicable after it is required, such notice shall be given by the
Company to the Trustee and all Holders in the manner provided for in Section 105
of the Indenture.  The Trustee shall not be deemed to have notice of any change
in the Conversion Rate unless and until it receives the Officers' Certificate
provided for in the foregoing clause (a) setting forth such change.

     2.7  NOTICE OF CERTAIN CORPORATE ACTION.

     In case: (a) the Company shall declare a dividend or make any other
distribution that would require any adjustment pursuant to Section 2.5 hereof;
or (b) the Company shall authorize the granting to the holders of its Common
Stock of rights or warrants to subscribe for or purchase any shares of capital
stock of any class or of any other rights; or (c) of any reclassification of the
Common Stock of the Company, or of any consolidation or merger to which the
Company is a party and for which approval of any stockholders of the Company is
required or that is otherwise subject to Section 2.12 hereof, or of the
conveyance, lease, sale or transfer of all or substantially all of the assets of
the Company; or (d) of the voluntary or involuntary dissolution, liquidation or
winding up of the Company; then the Company shall cause to be filed at each
office or agency maintained for the purpose of conversion of Securities pursuant
to Section 2.3 hereof, and shall cause to be mailed to all Holders at their last
addresses as they shall appear in the register for the Securities, at least 20
days prior to the applicable record or effective date hereinafter specified, a
notice (which notice shall also be sent by release to Reuters Economic Services
and Bloomberg Business News as set forth in Section 105 of the Indenture)
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution, rights 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 or warrants are to be determined, or (y) the
date on which such reclassification, consolidation, merger, share exchange,
conveyance, lease, sale, transfer, dissolution, liquidation or winding up is
expected to become effective, and the date as of which it is expected that
holders of Common Stock of record shall be entitled to exchange their shares of
Common Stock for securities, cash or other property deliverable upon such
reclassification, consolidation, merger, share exchange, conveyance, lease,
sale, 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 described in clauses (a) through (d) of this Section 2.7.  If at
the time the Trustee shall not be the conversion agent, a copy of such notice
shall also forthwith be filed by the Company with the Trustee.  The Company
shall cause to be filed at the Corporate Trust Office and each office or agency
maintained for the purpose of conversion of Notes pursuant to Section 305 of the
Indenture, and shall cause to be provided to all Holders in accordance with
Section 105 of the Indenture, notice

                                       11
<PAGE>

of any tender offer by the Company or any Subsidiary for all or any portion of
the Common Stock at or about the time that such notice of tender offer is
provided to the public generally.

     2.8  COMPANY TO RESERVE COMMON STOCK.

     The Company shall at all times reserve and keep available, free from
preemptive rights, out of its authorized but unissued Common Stock, for the
purpose of effecting the conversion of Notes, the full number of shares of
Common Stock then issuable upon the conversion of all outstanding Notes.

     2.9  TAXES ON CONVERSIONS.

     The Company will pay any and all taxes that may be payable in respect of
the issue or delivery of shares of Common Stock on conversion of Notes pursuant
hereto.  The Company shall not, however, be required to pay any tax which may be
payable in respect of any transfer involved in the issue and delivery of shares
of Common Stock in a name other than that of the Holder of the Note or Notes to
be converted, and no such issue or delivery shall be made unless and until the
Person requesting such issue has paid to the Company the amount of any such tax,
or has established to the satisfaction of the Company that such tax has been
paid.

     2.10  COVENANT AS TO COMMON STOCK.

     The Company covenants that all shares of Common Stock which may be issued
upon conversion of Notes will upon issue be fully paid and nonassessable and,
except as provided in Section 2.9 hereof, the Company will pay all taxes, liens
and charges with respect to the issue thereof.

     The Company will endeavor promptly to comply with all Federal and state
securities laws regulating the issuance and delivery of shares of Common Stock
upon conversion of Notes, if any, and will use its best efforts to list or cause
to have quoted all such shares of Common Stock on each United States national
securities exchange or over-the-counter or other domestic market on which the
Common Stock is then listed or quoted.

     2.11  CANCELLATION OF CONVERTED SECURITIES.

     All Notes delivered for conversion shall be delivered to the Trustee to be
canceled by or at the direction of the Trustee, which shall dispose of the same
as provided in Section 309 of the Indenture.

     2.12  PROVISIONS IN CASE OF CONSOLIDATION, MERGER OR SALE OF ASSETS.

     In case of any merger, amalgamation, arrangement or consolidation of the
Company with or into any other Person, any merger of another Person into the
Company (other than a merger, amalgamation, arrangement or consolidation which
does not result in any reclassification, conversion, exchange or cancellation of
outstanding shares of Common Stock of the Company) or any conveyance, lease,
sale or transfer of all or substantially all of the assets of the Company, the
Person formed by or resulting from such merger, amalgamation, arrangement or

                                       12
<PAGE>

consolidation or which acquires such assets, as the case may be, shall execute
and deliver to the Trustee a supplemental indenture providing (in addition to
matters, if any, required by Section 801 of the Indenture) that the Holder of
each Note then outstanding shall have the right thereafter, during the period
such Note shall be convertible as specified in Section 2.1 hereof, to convert
such Note only into the kind and amount of securities, cash and other property
receivable upon such merger, amalgamation, arrangement, consolidation,
conveyance, lease, sale or transfer by a holder of the number of shares of
Common Stock of the Company into which such Note might have been converted
immediately prior to such merger, amalgamation, arrangement, consolidation,
conveyance, lease, sale or transfer, assuming such holder of Common Stock of the
Company (i) is not a Person with which the Company consolidated or into which
the Company merged or which merged into the Company or to which such sale or
transfer was made, as the case may be ("Constituent Person"), or an Affiliate of
a Constituent Person and (ii) failed to exercise its rights of election, if any,
as to the kind or amount of securities, cash and other property receivable upon
such merger, amalgamation, arrangement, consolidation, conveyance, lease, sale
or transfer (provided that if the kind or amount of securities, cash and other
property receivable upon such merger, amalgamation, arrangement, consolidation,
conveyance, lease, sale or transfer is not the same for each share of Common
Stock of the Company held immediately prior to such merger, amalgamation,
arrangement, consolidation, conveyance, lease, sale or transfer by other than a
Constituent Person or an Affiliate thereof and in respect of which such rights
of election shall not have been exercised ("Non-Electing Share"), then for the
purpose of this Section 2.12 the kind and amount of securities, cash and other
property receivable upon such merger, amalgamation, arrangement, consolidation,
conveyance, lease, sale or transfer by 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
which, for events subsequent to the effective date of such supplemental
indenture, shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 2.  The foregoing provisions of this
Section 2.12 shall similarly apply to successive mergers, amalgamations,
arrangements, consolidations, conveyances, leases, sales or transfers.  The
Company shall cause notice of the execution of such supplemental indenture to be
given to each Holder in the manner provided for in Section 105 of the Indenture.

     2.13  RIGHT OF HOLDERS TO CONVERT.

     The limitations set forth in Section 507 of the Indenture shall not apply
to the right of a Holder to bring a suit for the enforcement of such Holder's
right to convert Notes pursuant to this Article 2.

                                   ARTICLE 3

                              REDEMPTION OF NOTES

                                   ARTICLE 4

                       REPURCHASE OF NOTES AT THE OPTION
                    OF THE HOLDERS UPON A CHANGE OF CONTROL

     Pursuant to Section 2.2(8) of the Indenture, so long as any of the Notes
are outstanding, the following provisions shall be applicable to the Notes:

     4.1  REPURCHASE AT OPTION OF HOLDERS UPON CHANGE OF CONTROL.

          (a)  Upon the occurrence of a Change of Control (the date of such
occurrence, the "Change of Control Date"), the Company shall notify the Holders
of the Notes in writing of such occurrence in accordance with paragraph (b)
below, and shall make an offer to purchase (a "Change of Control Offer"), and
shall purchase, on a Business Day (a "Change of Control Purchase Date") not more
than 60 nor less than 30 days following the Change of Control Date all of the
then outstanding Notes validly tendered at a purchase price in cash equal to
100% of the principal amount thereof plus accrued interest, if any, to the
Change of Control Purchase Date (the "Change of Control Purchase Price").

          (b)  Notice of a Change of Control Offer (a "Change of Control
Notice") shall be sent, by first-class mail, postage prepaid, by the Company not
later than the 30th day after the Change of Control Date to the Holders of the
Notes at their last registered addresses with a copy to the Trustee and the
Paying Agent (and shall also be given by release made to Reuters Economic
Services and Bloomberg Business News as provided in Section 10.2 of the
Indenture). The Change of Control Offer shall remain open from the time of
delivery of the Change of Control Notice for at least 20 Business Days and until
5:00 p.m., New York City time, on the Business Day prior to the Change of
Control Purchase Date. The Change of Control Notice, which shall govern the
terms of the Change of Control Offer, shall include such disclosures as are
required by law and shall state:

                                       14
<PAGE>

          (i)    that the Change of Control Offer is being made pursuant to this
Section 4.1 and that any portion of the principal amount of Notes that is equal
to $1,000 or an integral multiple thereof, validly tendered into the Change of
Control Offer and not withdrawn, will be accepted for payment;

          (ii)   the cash purchase price (including the amount of accrued
interest, if any) for each Note, the Change of Control Purchase Date and the
date on which the Change of Control Offer expires;

          (iii)  that any Note not tendered for payment will continue to accrue
interest in accordance with the terms thereof;

          (iv)   that, unless the Company shall default in the payment of the
Change of Control Purchase Price, any Note accepted for payment pursuant to the
Change of Control Offer shall cease to accrue interest after the Change of
Control Purchase Date;

          (v)    that Holders electing to have Notes purchased pursuant to a
Change of Control Offer will be required to surrender their Notes to the Paying
Agent at the address (in New York City) specified in the Change of Control
Notice prior to 5:00 p.m., New York City time, on the Business Day prior to the
Change of Control Purchase Date and must complete an election notice as set
forth in Exhibit A or any form of letter of transmittal proposed by the Company
and reasonably acceptable to the Trustee and the Paying Agent;

          (vi)   that Holders of Notes will be entitled to withdraw their
election if the Paying Agent receives, not later than 5:00 p.m., New York City
time, on the Business Day prior to the Change of Control Purchase Date, a
facsimile transmission or letter setting forth the name of the Holder, the
principal amount of Notes the Holder delivered for purchase, the Note
certificate number (if any) and a statement that such Holder is withdrawing its
election to have such Notes purchased;

          (vii)  that Holders whose Notes are purchased only in part will be
issued Notes equal in principal amount to the unpurchased portion of the Notes
surrendered;

          (viii) the instructions that Holders must follow in order to tender
their Notes; and

          (ix)   information concerning the business of the Company, the most
recent annual and quarterly reports of the Company filed with the SEC pursuant
to the Exchange Act (or, if the Company is not then permitted to file any such
reports with the SEC, the comparable reports prepared pursuant to Section 4.2 of
the Indenture), a description of material developments in the Company's
business, information with respect to pro forma historical financial information
after giving effect to such Change of Control and such other information
concerning the circumstances and relevant facts regarding such Change of Control
Offer as would be material to a Holder of Notes in connection with the decision
of such Holder as to whether or not it should tender Notes pursuant to the
Change of Control Offer.

                                       15
<PAGE>

          (c)  To exercise a repurchase right pursuant to this Section 4.1, a
Holder shall deliver to the Trustee a written notice (a "Repurchase Notice") of
such Holder's exercise of such right, in accordance with the terms and
conditions set forth in the Change of Control Notice. Upon receipt by the
Trustee of a Repurchase Notice, the Holder of the Note in respect of which such
Repurchase Notice was given shall (unless such Repurchase Notice is withdrawn)
thereafter be entitled to receive solely the Change of Control Purchase Price
with respect to such Note. Notes in respect of which a Repurchase Notice has
been given by the Holder thereof may not be converted into shares of Common
Stock on or after the date of the delivery of such Repurchase Notice, unless
such Repurchase Notice has first been validly withdrawn as set forth in the
foregoing paragraph (b)(vi), unless the Company has defaulted in the payment of
the Change of Control Purchase Price.

          (d)  On the Change of Control Purchase Date, the Company shall (i)
accept for payment Notes or portions thereof validly tendered pursuant to the
Change of Control Offer, (ii) deposit with the Paying Agent (no later than 10:00
A.M. EST on the Change of Control Purchase Date) money, in immediately available
funds, sufficient to pay the purchase price of all Notes or portions thereof so
tendered and accepted and (iii) deliver to the Trustee the Notes so accepted
together with an Officers' Certificate setting forth the Notes or portions
thereof tendered to and accepted for payment by the Company. The Paying Agent
shall promptly mail or deliver to the Holders of Notes so accepted payment in an
amount equal to the purchase price, and the Trustee shall promptly authenticate
and mail or deliver to such Holders a new Note equal in principal amount to any
unpurchased portion to the Notes surrendered; provided that each such new Note
shall be issued in an original principal amount in denominations of $1,000 and
integral multiples thereof. Any Notes not validly tendered and not accepted by

Exchange Act at that time, the Company will comply with the requirements of Rule
14e-1 as then in effect with respect to such repurchase.

CUSIP No. 74406A AA 0

     PROVIDIAN FINANCIAL CORPORATION, a corporation duly organized and existing
under the laws of the State of Delaware (herein called the "Company", which term
includes any successor Person under the Indenture hereinafter defined), for
value received, hereby promises to pay to CEDE & CO., or registered assigns, the
principal sum of $___________  (____________ Dollars) on August 15, 2005, and to
pay interest thereon from August 23, 2000 or from the most recent Interest
Payment Date to which interest has been paid or duly provided for, semi-annually
on February 15 and August 15 in each year, commencing February 15, 2001, at the
rate of 3.25% per annum, until the principal hereof is paid or made available
for payment.

     The interest so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Indenture, be paid to the Person
in whose name this Note is registered at the close of business on the regular
record date for such interest, which shall be the 1st of February or 1st of
August, as the case may be, next preceding such Interest Payment Date or, if
such record date is not a Business Day, at the close of business of the
immediately succeeding Business Day.  A "Business Day" shall mean any day other
than a Saturday, Sunday, a federally recognized holiday or a day on which
banking institutions are not authorized or required by law or executive order to
be open in the State of New York.  Any such interest not so punctually paid or
duly provided for will forthwith cease to be payable to the Holder on such
regular record date and shall be paid to the Person in whose name this Note is
registered at the close of business on a subsequent special record date, which
date shall be the fifteenth day next preceding the date fixed by the Company for
the payment of defaulted interest or the next succeeding Business Day if such
date is not a Business Day.  At least 15 days before the special record date,
the Company shall mail or cause to be mailed to each Holder, with a copy to the

                                      A-1
<PAGE>

Trustee, a notice that states the special record date, the payment date, and the
amount of defaulted interest, and interest payable on such defaulted interest,
if any, to be paid.

     Payments of principal of and interest on this Note and any additional
payments due hereunder shall be made at the office or agency of the Company
maintained for that purpose in the Borough of Manhattan, The City of New York,
in such coin or currency of the United States of America as at the time of
payment is legal tender for payment of public and private debts; provided,
however, that at the option of the Company payment of interest may be made by
check mailed to the address of the Person entitled thereto as such address shall
appear in the register for the Notes maintained by the Registrar.

     Reference is hereby made to the further provisions of this Note set forth
on the reverse hereof, which further provisions shall for all purposes have the
same effect as if set forth at this place.

     Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof or an authenticating agent appointed
by the Company, by manual signature, this Note shall not be entitled to any

                           [FORM OF REVERSE OF NOTE]

     This Note is one of a duly authorized issue of securities of the Company
(herein called the "Notes"), issued and to be issued in one or more series under
an Indenture, dated as of May 1, 1999 (as supplemented by a First Supplemental
Indenture, dated as of August 23, 2000, the "Indenture"), between the Company
and Bank One Trust Company, N.A., as Trustee (herein called the "Trustee", which
term includes any successor trustee under the Indenture), and reference is
hereby made to the Indenture for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the
Trustee, and the Holders of the Notes and of the terms upon which the Notes are,
and are to be, authenticated and delivered.  This Note is one of the series
designated on the face hereof as "3.25% Convertible Senior Notes due August 15,
2005", limited in aggregate principal amount to $402,500,000.  All terms used in
this Note which are defined in the Indenture shall have the meanings assigned to
them in the Indenture.

     The Notes are subject to redemption, at the election of the Company, at any
time on or after August 20, 2003, as a whole or in part, upon not less than 30
nor more than 60 days' notice to the Holders (in the manner provided for in the
Indenture) prior to the Redemption Date at the following redemption prices
(expressed as percentages of the principal amount):

<TABLE>
<CAPTION>
        Redemption Date                                 Redemption Price:
        ---------------                                 ----------------
        <S>                                             <C>
        from August 20, 2003 until August 14, 2004            101.30%
        from August 15, 2004 until Stated Maturity            100.65%
</TABLE>

together in each case of any such redemption with accrued interest to the
Redemption Date; provided, however, that interest installments whose payment
date is on or prior to such Redemption Date will be payable to the Holders of
such Notes of record at the close of business on the relevant Record Dates
referred to on the face hereof, all as provided in the Indenture.

     No sinking fund is provided for the Notes.

     Subject to and upon compliance with the provisions of the Indenture, any
Note (or any portion of the principal amount thereof which is $1,000 or an
integral multiple of $1,000) which has not previously been redeemed or
repurchased, is convertible at the option of the Holder thereof, at any time
following the original issue date of the Notes and on or before the close of
business on the Business Day immediately preceding the Stated Maturity, into
fully paid and nonassessable shares of common stock of the Company, $0.01 par
value per share (the "Common Stock"), at an initial conversion rate (calculated
to the nearest 1/100 of a share) of 7.2446 shares of Common Stock for each
$1,000 principal amount of Note, or at the current adjusted conversion rate if
an adjustment has been made as provided in the Indenture.  In case the Notes or
a portion thereof are called for redemption, such conversion right in respect of
the Notes or portion so called shall expire at the close of business on the
Business Day immediately preceding the Redemption Date, unless the Company
defaults in making the payment due upon redemption.  A Note or portion thereof
in respect of which the Holder has delivered a Repurchase Notice may be
converted only if such notice is withdrawn in accordance with the terms of the
Indenture, unless the Company has defaulted in the payment of the Change of

                                      A-4
<PAGE>

Control Purchase Price.  The Holder of a Note surrendered for conversion during
the period from the close of business on any Record Date immediately preceding
any Interest Payment Date to the opening of business on such Interest Payment
Date shall (except in the case of a Note or portions thereof which have been
called for redemption or in respect of which the Repurchase Notice delivered by
the Holder has not been withdrawn, the conversion rights of which would
terminate during the period between such Record Date and the close of business
on such Interest Payment Date) be entitled to receive the interest payable on
such Interest Payment Date on the principal amount of the Note being surrendered
for conversion.  To convert this Note the Holder must (1) surrender this Note,
duly endorsed or assigned to the Company or in blank, provided that if such
surrender shall be made during the period from the close of business on any
Record Date immediately preceding any Interest Payment Date to the opening of
business on such Interest Payment Date shall (except in the case of Notes or
portions thereof which have been called for redemption or in respect of which
the Repurchase Notice delivered by the Holder has not been withdrawn, the
conversion rights of which would terminate during the period between such Record
Date and the close of business on such Interest Payment Date) also be
accompanied by payment in immediately available funds or other funds acceptable
to the Company of an amount equal to the interest payable on such Interest
Payment Date on the principal amount of the Note being surrendered for
conversion, and (2) complete and manually sign a conversion notice in
substantially the form attached hereto.  Except as set forth above, no payment
or adjustment shall be made upon any conversion on account of any interest
accrued hereon from the Interest Payment Date immediately preceding the day of
conversion, or on account of any dividends on the Common Stock issued on
conversion hereof.  In addition, the Holders shall not be entitled to receive
any dividends payable to holders of Common Stock as of any record date before
the close of business on the conversion date.  No fractional shares will be
issued on conversion, but instead of any fractional interest (calculated to the
nearest 1/100th of a share) the Company shall pay a cash adjustment as provided
in the Indenture.

     The Indenture provides that in the event of any merger, amalgamation,
arrangement or consolidation to which the Company is a party (other than one
that does not result in any reclassification, conversion, exchange or
cancellation of the Common Stock) or any conveyance, lease, sale or transfer of
all or substantially all of the assets of the Company, the Indenture shall be
amended, without the consent of any Holders of Notes, so that this Note, if then
outstanding, will be convertible thereafter, during the period this Note shall
be convertible as specified above, only into the kind and amount of securities,
cash and other property receivable upon such merger, amalgamation, arrangement,
consolidation, conveyance, lease, sale or transfer by a holder of the number of
shares of Common Stock of the Company into which this Note could have been
converted immediately prior to such merger, amalgamation, arrangement,
consolidation, conveyance, lease, sale or transfer (assuming such holder of
Common Stock is not a Constituent Person or an Affiliate of a Constituent
Person, failed to exercise any rights of election and received per share the
kind and amount received per share by a plurality of Non-Electing Shares).  No
adjustment in the Conversion Rate shall be made until such adjustment would
require an increase or decrease of at least one percent of such rate, provided
that any adjustment that would otherwise be made will be carried forward and
taken into account in the computation of any subsequent adjustment.

     Subject to and upon compliance with the provisions of the Indenture, upon
the occurrence of a Change of Control, the Company shall notify the Holders of
the Notes of such occurrence by

                                      A-5
<PAGE>

delivering a Change of Control Notice, shall make a Change of Control Offer and
shall purchase, on a Business Day not more than 60 nor less than 30 days
following the Change of Control Date (a "Change of Control Purchase Date") all
of the then outstanding Notes validly tendered at a purchase price in cash equal
to 100% of the principal amount thereof plus accrued interest, if any, to the
Change of Control Purchase Date (the "Change of Control Purchase Price"). The
Change of Control Offer shall remain open from the time of delivery of the
Change of Control Notice for at least 20 Business Days and until 5:00 p.m., New
York City time, on the Business Day prior to the Change of Control Purchase
Date. To exercise its repurchase right, a Holder shall deliver to the Trustee a
Repurchase Notice, in accordance with the terms and conditions set forth in the
Change of Control Notice. Upon receipt by the Trustee of a Repurchase Notice,
the Holder of the Note in respect of which such Repurchase Notice was given
shall (unless such Repurchase Notice is withdrawn) thereafter be entitled to
receive solely the Change of Control Purchase Price with respect to such Note
and, unless the Company has defaulted in the payment of the Change of Control
Purchase Price, any Note accepted for payment pursuant to the Change of Control
Offer shall cease to accrue interest after the Change of Control Purchase Date.
Holders of Notes will be entitled to withdraw their election if the Paying Agent
receives notice of such withdrawal not later than 5:00 p.m., New York City time,
on the Business Day prior to the Change of Control Purchase Date. Notes in
respect of which a Repurchase Notice has been given by the Holder thereof may
not be converted into shares of Common Stock on or after the date of the
delivery of such Repurchase Notice, unless such Repurchase Notice has first been
validly withdrawn in the manner provided for in the Indenture or unless the
Company has defaulted in the payment of the Change of Control Purchase Price.
Holders electing to have Notes purchased pursuant to a Change of Control Offer
will be required to surrender their Notes to the Paying Agent at the address (in
the Borough of Manhattan, The City of New York) specified in the Change of
Control Notice prior to 5:00 p.m., New York City time, on the Business Day prior
to the Change of Control Purchase Date and must complete any form of letter of
transmittal proposed by the Company and reasonably acceptable to the Trustee and
the Paying Agent. Any portion of the principal amount of Notes that is equal to
$1,000 or an integral multiple thereof, validly tendered into the Change of
Control Offer and not withdrawn, will be accepted for payment.

     In the event of redemption, repurchase or conversion of this Note in part
only, a new Note or Notes for the unredeemed, unrepurchased or unconverted
portion hereof will be issued in the name of the Holder hereof upon the
cancellation thereof.

     The provisions for defeasance and covenant defeasance set forth in Sections
1302 and 1303 of the Indenture, respectively, will not apply to the Notes.

     If an Event of Default with respect to the Notes shall occur and be
continuing, the principal of all the Notes may be declared due and payable in
the manner and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Notes under the Indenture at any
time by the Company and the Trustee with the consent of the Holders of 66 2/3%
in principal amount of the Notes at the time Outstanding.  The Indenture also
contains provisions permitting the Holders of a majority in principal amount of

the Notes at the time Outstanding, on behalf of the Holders of all Notes, to
waive compliance by the Company with certain provisions of the Indenture and
certain past defaults under the Indenture and their consequences.  Any such
consent or waiver by the Holder of this Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Note and of any Note issued
upon the registration of transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Note.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Note shall not have the right to institute any proceeding with respect
to the Indenture or for the appointment of a receiver or trustee or for any
other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Notes, the Holders of not less than 25% in principal amount of the Notes at the
time Outstanding shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity, and the Trustee shall not have received from the
Holders of a majority in principal amount of the Notes at the time Outstanding a
direction inconsistent with such request, and shall have failed to institute any
such proceeding, for 60 days after receipt of such notice, request and offer of
indemnity.  The foregoing shall not apply to any suit instituted by the Holder
of this Note for the enforcement of any payment of principal hereof or any
premium or interest hereon on or after the respective due dates expressed herein
or for the enforcement of the right to convert this Note as provided in the
Indenture.

     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 times, place and rate, and in the coin or currency, herein
prescribed or to convert this Note as provided in the Indenture.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Note is registrable in the Security Register, upon
surrender of this Note for registration of transfer at the office or agency of
the Company in any place where the principal of and any premium and interest on
this Note are payable, duly endorsed by, or accompanied by a written instrument
of transfer in form satisfactory to the Company and the Security Registrar duly
executed by, the Holder hereof or such Holder's attorney duly authorized in
writing, and thereupon one or more new Notes, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

     This Note is a Global Note and shall be exchangeable for Notes registered
in the names of Persons other than the Depositary with respect to this Global
Note or its nominee only if (A) such Depositary notifies the Company that it is
unwilling or unable to continue as Depositary for this Global Note or at any
time ceases to be a clearing agency registered as such under the Securities
Exchange Act of 1934, as amended, (B) the Company in its discretion executes and
delivers to the Trustee a Company Order that this Global Note shall be
exchangeable or (C) there shall have occurred and be continuing an Event of
Default with respect to the Notes.  If this Global Note is exchangeable pursuant
to the preceding sentence, it shall be exchangeable for Notes issuable in
denominations of $1,000 and any integral multiple of $1,000 in excess thereof,
registered in such names as such Depositary shall direct.

     The Notes are issuable only in registered form without coupons in
denominations of $1,000 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, the Notes are
exchangeable for a like aggregate principal amount of Notes of a different
authorized denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name this Note is registered as the owner hereof for all
purposes, whether or not this Note be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

     A director, officer, employee, stockholder or incorporator, as such, of the
Company shall not have any liability (except in the case of bad faith or willful
misconduct) for any obligations of the Company under the Notes or the Indenture
or for any claim based on, in respect of or by reason of such obligations or
their creations.  Each Holder by accepting a Note waives and releases all such
liability.  Such waiver and release are part of the consideration for the
issuance of the Notes.

     THE INDENTURE AND THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE
AND PERFORMED WITHIN THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF
CONFLICTS OF LAW.
