                                  COMMON STOCK
                                ($0.50 PAR VALUE)

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

     This prospectus ("Prospectus") relates to the offering from time to time by
certain stockholders (the "Selling Stockholders") of 6,048,387 shares (the
"Shares") of Common Stock, $0.50 par value per share, of National Semiconductor
Corporation ("National" or the "Company") which are issuable upon conversion of
the Company's outstanding 6 1/2% Convertible Subordinated Notes due 2002 (the
"Notes").  The Company will not receive any proceeds from the Offering.

     The Selling Stockholders directly, or through agents, dealers,
underwriters, or market makers, may offer and sell from time to time all or any
part of the Shares in amounts and on terms to be determined at the time of sale.
To the extent required, the specific Shares to be sold, the names of the Selling
Stockholders, the respective purchase price and public offering price, the names
of any such agent, dealer or underwriter, and any applicable commission or
discount with respect to a particular offer will be set forth in an accompanying
Prospectus Supplement.  Offers or sales of the Shares have not been registered
or qualified under the laws of any country other than the United States.  See
"Plan of Distribution."

     The aggregate proceeds to the Selling Stockholders from the sale of the
Shares will be the purchase price of the Shares sold less the aggregate agents'
commissions and underwriters' discounts, if any.  By agreement, the Company will
pay substantially all of the expenses incident to the registration of the
Shares, except for underwriting discounts and selling commissions associated
with the sale of the Shares, all of which shall be paid by the Selling
Stockholders.  See "Plan of Distribution" herein for a description of
indemnification arrangements for the Selling Stockholders.

     The closing price of the Company's Common Stock as reported on the New York
Stock Exchange, Inc. on October 24, 1995, was $26.00 per share.

     On October 24, 1995 the last reported sale price for the Common Stock on
the NYSE Composite Transactions Tape was $26.00 per share.

     The Company has not paid any cash dividends on its Common Stock and has
no plans to pay cash dividends on its Common Stock in the foreseeable future.
Although the Company's loan agreements do not directly limit the payment of
dividends on the Company's Common Stock and Preferred Stock, these agreements
require the Company to comply with certain financial covenants that are
affected by dividend payments. At May 28, 1995, under the most restrictive
covenant, no more than $238.5 million was available for payment of dividends
on the Company's Common Stock.

(1)  Fiscal 1991, 1993, 1994 and 1995 were 52-week years whereas fiscal 1992 was
     a 53-week year.

(2)  Beginning in the quarter ended August 27, 1995, the Company reclassified as
     other income, net, certain non-operating items that were previously
     reported as selling, general and administrative expenses. Such items
     included net intellectual property income and gain on sale of investments,
     net. Prior periods have been restated to conform to the fiscal 1996
     presentation. The effect of such restatement was to reduce previously
     reported operating income or increase previously reported operating loss by
     $6.3 million, $21.6 million, $27.1 million, $18.1 million and $30.6 million
     for the fiscal years ended May 26, 1991, May 31, 1992, May 30, 1993,
     May 29, 1994 and May 28, 1995, respectively, and by $4.8 million,
     $4.0 million, $7.4 million, $14.4 million for the three month periods ended
     August 28, 1994, November 27, 1994, February 26, 1995, and May 28, 1995,
     respectively. The reclassifications had no impact on previously reported
     net income.

(3)  For the purpose of calculating the ratio of earnings to fixed charges,
     (i) earnings consist of income before income taxes and before cumulative
     effect of accounting change, plus fixed charges and (ii) fixed charges
     consist of interest expense incurred, amortization of debt expense and the
     portion of rental expense deemed by the Company to be representative of the
     interest factor of rental payments under operating leases. Earnings were
     inadequate to cover fixed charges by $149.0 million and $117.0 million in
     the fiscal years ended May 26, 1991 and May 31, 1992, respectively. The pro
     forma ratio of earnings to fixed charges reflects the interest expense on
     the Notes, as if the Notes had been issued at the beginning of the
     respective periods presented.

                                 USE OF PROCEEDS

     The Company will not receive any proceeds from the sale of Common Stock by
the Selling Stockholders.



                              SELLING STOCKHOLDERS

     The Selling Stockholders will have received their shares upon conversion
of the 6-1/2% Convertible Subordinated Notes Due 2002 of the Company (the
"Notes"). In connection with the issuance of the Notes, the Company agreed to
file a registration statement with the Commission covering the resale of the
Shares issuable upon conversion of the Notes and to indemnify each Selling
Stockholder against claims made against them arising out of, among other
things, statements made in such registration statement.  In addition, the
Company agreed to cause this registration statement to remain effective for
the earlier of three years or until all of the Shares are sold. The Company
has undertaken to distribute, as necessary, one or more Prospectus
Supplements which will set forth, to the extent required, the specific number
of Shares to be sold, the names of the Selling Stockholders, the respective
purchase price, the name of any dealers, agents or underwriters and any
applicable commission or discount with respect to a particular offer.

                          DESCRIPTION OF CAPITAL STOCK

     The authorized capital stock of the Company consists of 300,000,000 shares
of Common Stock, $0.50 par value, and 1,000,000 shares of Preferred Stock, $0.50
par value. As of August 27, 1995, 123,388,745 shares of Common Stock were
outstanding, and 345,000 shares of $32.50 Convertible Preferred Stock and
3,450,000 Depositary Shares associated with the $32.50 Convertible Preferred
Stock were outstanding.

COMMON STOCK

     Each share of Common Stock entitles the holder to one vote on matters
submitted to a vote of the stockholders (cumulative voting may be invoked in
connection with the election of directors), and, subject to the prior
preferences of the Company's Preferred Stock, a pro rata share of assets
remaining available for distribution to stockholders upon a liquidation of the
Company. Dividends may be paid to the holders of the Common Stock when and if
declared by the Board of Directors out of funds legally available therefor, and
after payment of dividends and sinking fund payments on outstanding Preferred
Stock, if any. The Company has not paid any cash dividends on its Common Stock.
The Common Stock is not convertible and has no preemptive rights. There are no
redemption provisions with respect to the Common Stock. All of the outstanding
shares of Common Stock are, and the shares of Common Stock issuable upon
conversion of the Notes will be, fully paid and non-assessable.

     The transfer agent and registrar for the Company's Common Stock is The
First National Bank of Boston.

PREFERRED STOCK

     The Company's Certificate of Incorporation and Bylaws provide that
Preferred Stock may be issued from time-to-time in one or more series. The
Company's Board of Directors has authority to fix or alter the dividend rights,
dividend rate, conversion rights, voting rights, rights and terms of redemption
(including sinking fund provisions), redemption prices, and liquidation
preferences of any wholly unissued series of Preferred Stock, as well as the
number of shares constituting any such unissued series and the designation
thereof, and to increase or decrease the number of shares of any outstanding
series (but not below the number of shares of such series then outstanding),
without any further vote or action by the Company's stockholders.

 $32.50 CONVERTIBLE PREFERRED STOCK.  The Company issued 345,000 shares of
$32.50 Convertible Preferred Stock, $0.50 par value (the "Convertible Preferred
Shares") in October 1992. All Convertible Preferred Shares are currently held by
a Depositary, which has issued Depositary Shares at the rate of 10 Depositary
Shares for each Convertible Preferred Share held by the Depositary. Each owner
of a Depositary Share is entitled, proportionately, to all of the rights and
preferences of a holder of one-tenth of a Convertible Preferred Share. The
liquidation preference of each Convertible Preferred Share is $500 plus unpaid
dividends. The Convertible Preferred Shares are convertible at any time at the
option of the holder into Common Stock at the rate of 35.273 shares of Common
Stock for each Convertible Preferred Share. On or after November 1, 1995, and if
the closing price of the Company's Common Stock on the New York Stock Exchange
exceeds $17.72 for twenty trading days within any period of thirty consecutive
trading days, the Convertible Preferred Shares are redeemable, in whole or in
part, at the option of the Company for the number of shares of Common Stock as
are issuable at a conversion rate of 35.273 shares of Common Stock for each
Convertible Preferred Share. The Convertible Preferred Shares are not entitled
to the benefit of any sinking fund. Dividends on the Convertible Preferred
Shares at an annual rate of $32.50 per share are cumulative and payable
quarterly in arrears, when and as declared by the Company's Board of Directors.
Holders of Convertible Preferred Shares are entitled to limited voting rights.

 PREFERRED STOCK RIGHTS AGREEMENT.  On August 5, 1988 the Board of Directors of
the Company approved a Preferred Stock Rights Agreement and declared a dividend
distribution payable August 19, 1988 of one Preferred Share Purchase Right (the
"Rights") for each share of its Common Stock outstanding on August 19, 1988 and
each share of its Common Stock issued thereafter (subject to certain
limitations).

     Currently, the Rights trade with the shares of Common Stock. When the
Rights become exercisable, each Right will entitle the holder to buy one
one-thousandth of a share of Series A Junior Participating Preferred Stock, $.50

                                       10

par value, at an exercise price of $60 per one one-thousandth of a share. The
Rights will become exercisable and will trade separately from the Common Stock
on the earlier of (i) 10 days following a public announcement that a person or
group has acquired, or obtained the right to acquire, beneficial ownership of
20% or more of the outstanding Common Stock, or (ii) 10 days (unless postponed
by action of the Board of Directors) following the commencement or announcement
of a tender offer or exchange offer which, if consummated, would result in the
beneficial ownership by a person or group of 20% or more of the Company's
outstanding Common Stock.

     In general, if any person or group acquires 30% or more of the Company's
Common Stock without approval of the Company's Board of Directors, each Right
not held by the acquiring person will entitle its holder to purchase $120 worth
of the Company's Common Stock for an effective purchase price of $60. If, after
any person or group acquires 30% or more of the Company's Common Stock without
the approval of the Board of Directors, the Company is acquired in a merger or
other business combination transaction, each Right not held by the acquiring
person would entitle its holder to purchase $120 worth of the common stock of
the acquiring company for $60. Under certain conditions, the Company may elect
to redeem the Rights for $.01 per Right or cause the exchange of each Right not
held by the acquiring person for one share of the Company's Common Stock.
Additionally, the exercise price, number of Rights, and number of shares of
Series A Junior Participating Preferred or Common Stock that may be acquired for
the exercise price are subject to adjustment from time to time to prevent
dilution. The Rights expire on August 8, 1998, unless previously exchanged or
redeemed as described above or terminated in connection with an acquisition of
the Company by consolidation or merger which is approved by the Board of
Directors and satisfies certain conditions.

     The Rights may have the effect of rendering more difficult or discouraging
an acquisition of the Company deemed undesirable by the Board of Directors by
causing substantial dilution to a person or group that attempts to acquire the
Company on terms or in a manner not approved by the Company's Board of
Directors, except pursuant to an offer conditioned upon the negation, purchase
or redemption of the Rights.

     The description above is qualified in its entirety by reference to the
Rights Agreement dated as of August 8, 1988.

DELAWARE GENERAL CORPORATION LAW SECTION 203

     As a corporation organized under the laws of the State of Delaware, the
Company is subject to Section 203 of the Delaware General Corporation Law, which
restricts certain business combinations between the Company and an "interested
stockholder" (in general, a stockholder owning 15% or more of the Company's
outstanding voting stock) or such stockholder's affiliates or associates for a
period of three years following the date on which the stockholder becomes an
"interested stockholder." The restrictions do not apply if (i) prior to an
interested stockholder becoming such, the Board of Directors approves either the
business combination or the transaction in which the stockholder becomes an
interested stockholder, (ii) upon consummation of the transaction in which such
stockholder becomes an interested stockholder, such interested stockholder owns
at least 85% of the voting stock of the Company outstanding at the time the
transaction commenced (excluding shares owned by certain employee stock
ownership plans and persons who are both directors and officers of the Company),
or (iii) on or subsequent to the date an interested stockholder becomes such,
the business combination is both approved by the Board of Directors and
authorized at an annual or special meeting of the Company's stockholders (and
not by written consent) by the affirmative vote of at least 66 2/3% of the
outstanding voting stock not owned by the interested stockholder.

                              PLAN OF DISTRIBUTION

     The Shares may be sold from time to time by any of the Selling Stockholders
or by donees or transferees, directly or through underwriters, dealers or
agents, who may receive compensation in the form of underwriting discounts,
concessions or commissions from the Selling Stockholders or the purchasers of
Shares for whom they may act as agent.  The Shares or any part of the Shares may
be sold in amounts and on terms to be determined at the time of sale, including,
without limitation, block trades, in the over-the-counter market, through an
exchange or otherwise, at negotiated prices or at or relating to quoted market
prices then prevailing. The Selling Stockholders reserve the sole right to
accept and, together with any agent of the Selling Stockholders, to reject in
whole or in part any proposed purchase of the Shares. The Selling Stockholders
will pay any sales commissions or other seller's compensation applicable to such
transactions.

     To the extent required, the amount of the Shares to be sold, purchase
prices, public offering prices, the names of any agents, dealers or
underwriters, and any applicable commissions or discounts with respect to a
particular offer will be set forth by the Company in a Prospectus Supplement
accompanying this Prospectus or, if appropriate, a post-effective amendment to
the Registration Statement. The Selling Stockholders and agents who execute
orders on their behalf may be deemed to be underwriters as that term is defined
in Section 2(11) of the Securities Act and a portion of any proceeds of sales
and discounts, commissions or other seller's compensation may be deemed to be
underwriting compensation for purposes of the Securities Act.

     Offers or sales of the Shares have not been registered or qualified under
the laws of any country, other than the United States.  To comply with certain
states' securities laws, if applicable, the Shares will be offered or sold in
such jurisdictions only through registered or licensed brokers or dealers.  In
addition, in certain states the Shares may not be offered or sold unless they
have been registered or qualified for sale in such states or an exemption from
registration or qualification is available and is complied with.

     Under applicable rules and regulations under the Exchange Act any person
engaged in a distribution of the Shares may not simultaneously engage in
market-making activities with respect to such Shares for a period of two to nine
business days prior to the commencement of such distribution.  In addition to
and without limiting the foregoing, each Selling Stockholder and any other
person participating in a distribution will be subject to applicable provisions
of the Exchange Act and the rules and regulations thereunder, including without
limitation Rules 10b-2, 10b-6 and 10b-7, which provisions may limit the timing
of purchases and sales of any of the Shares by the Selling Stockholders or any
such other person.  All of the foregoing may affect the marketability of the
Shares and the brokers' and dealers' ability to engage in market-making
activities with respect to the Shares.

     Pursuant to an agreement with the Selling Stockholders, the Company will
pay substantially all of the expenses incident to the registration of the
Shares, estimated to be approximately $75,000.  Under agreements entered into
with the Company, the Selling Stockholders will be indemnified by the Company
against certain civil liabilities, including liabilities under the Securities
Act.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 102(b)(7) of the Delaware General Corporation Law permits a

of its directors shall be limited to the fullest extent permitted by applicable
law.

     Section 145 of the Delaware General Corporation Law contains provisions
permitting corporations to indemnify any person who is or was a director,
officer, employee or agent of the corporation, or who is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, in
accordance with the provisions set forth therein.  The Bylaws of the Company
generally provide for indemnification of such persons to the fullest extent
allowed by applicable law.

ITEM 17.  UNDERTAKINGS.

          The undersigned registrant hereby undertakes:

               (1)   To file, during any period in which offers or sales are
          being made, a post-effective amendment to this registration statement:

               (i)   To include any prospectus required by section 10(a)(3) of
                     the Securities Act of 1933, as amended (the "Securities
                     Act");

               (ii)  To reflect in the prospectus any facts or events arising
                     after the effective date of the registration statement (or
                     the most recent post-effective amendment thereof which,
                     individually or in the aggregate, represent a fundamental
                     change in the information set forth in the registration
                     statement;

               (iii) To include any material information with respect to the
                     plan of distribution not previously disclosed in the
                     registration statement or any material change to such
                     information in the registration statement;

          Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
     apply if the information required to be included in a post-effective
     amendment by those paragraphs is contained in periodic reports filed by the
     Company pursuant to section 13 or section 15(d) of the Securities Exchange
     Act of 1934, as amended (the "Exchange Act"), that are incorporated by
     reference in the registration statement.

          (2)  That, for the purpose of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered therein, and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

          (3)  To remove from registration by means of a post-effective
     amendment any of the securities being registered which remain unsold at the
     termination of the offering.

     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

"Purchasers") $225,000,000 principal amount of its 6 1/2% Convertible
Subordinated Notes due 2002 (the "Firm Offered Securities") to be issued

the right to purchase such 6 1/2% Convertible Subordinated Notes due 2002

     The Offered Securities will be convertible, on the terms and subject to the

     The Securities will be offered without being registered under the
Securities Act of 1933, as amended (the "Securities Act"), in reliance on
exemptions therefrom.

     In connection with the sale of the Offered Securities, the Company has

          (r)  In the ordinary course of its business, the Company conducts a
periodic review of the effect of Environmental Laws on the business, operations
and properties of the Company and its subsidiaries, in the course of which it
identifies and evaluates associated costs and liabilities (including, without
limitation, any capital or operating expenditures required for clean-up, closure
of properties or compliance with Environmental Laws or any permit, license or
approval, any related constraints on operating activities and any potential
liabilities to third parties).  On the basis of such review, the Company has
reasonably concluded that such associated costs and liabilities would not,
singly or in the aggregate, have a material adverse effect on the Company and
its subsidiaries, taken as a whole.

          (s)  The Company and each of its subsidiaries owns or possesses or has
adequate licenses or rights to use all patents, patent rights, licenses,
inventions, copyrights, know-how (including trade secrets and other unpatented

authorizations and trade names necessary (in any material respect) to the
conduct of the business as now operated by them, except such as are not material
to the business of the Company and its subsidiaries taken as a whole.  The
Company or any of its subsidiaries has no knowledge of any material infringement
by it of trademarks, trade name rights, patent rights, mask works, copyrights,
licenses, trade secrets or similar rights of others and neither the Company or
any of its subsidiaries has received any notice of infringement of or conflict
with asserted rights of others with respect to any of the foregoing which, in
either case, singly or in the aggregate, would have a material adverse effect on
the Company and its subsidiaries, taken as a whole, and except those which have
been resolved through a licensing or other similar arrangement which, singularly
or in the aggregate, did not have a material adverse effect on the Company and
its subsidiaries, taken as a whole.

          (t)  The Company has complied with all provisions of Section 517.075,
Florida Statutes (Chapter 92-198, Laws of Florida).

          (u)  The Company and each of its subsidiaries maintain a system of
internal accounting controls sufficient to provide reasonable assurance that
(i) transactions are executed in accordance with management's general or
specific authorizations; (ii) transactions are recorded as necessary to permit
preparation of financial statements in conformity with generally accepted
accounting principles and to maintain asset accountability; (iii) access to
assets is permitted only in accordance with management's general or specific
authorization; and (iv) the recorded


                                       -6-

<PAGE>

accountability for assets is compared with the existing assets at reasonable
intervals and appropriate action is taken with respect to any differences.

          (v)  No material labor dispute with the employees of the Company or
any of its subsidiaries exists or, to the best knowledge of the Company, is
imminent; and the Company is not aware of any existing, threatened or imminent
labor disturbance by the employees of any of its principal suppliers,
manufacturers or contractors that could result in any material adverse change in
the condition, financial or otherwise, or in the earnings, business or
operations of the Company and its subsidiaries, taken as a whole.

          (w)  None of the Company, its Affiliates or any person acting on its
or their behalf (other than the Purchasers) has engaged in any directed selling
efforts (as that term is defined in Regulation S under the Securities Act
("Regulation S") with respect to the Offered Securities and the Company and its
Affiliates and any person acting on its or their behalf (other than the
Purchasers) has complied with the offering restrictions requirement of
Regulation S.

          (x)  The Offered Securities satisfy the requirements set forth in
Rule 144A(d) (3) under the Securities Act.

     2.   OFFERING.  You have advised the Company that the Purchasers will make
an offering of the Offered Securities purchased by the Purchasers hereunder on
the terms to be set forth in the Final Memorandum, as soon as practicable after
this Agreement is entered into as in your judgment is advisable.

     3.   PURCHASE AND DELIVERY.  The Company hereby agrees to sell to the
several Purchasers, and the Purchasers, upon the basis of the representations
and warranties herein contained, but subject to the conditions hereinafter
stated, agree, severally and not jointly, to purchase from the Company the
respective principal amount of Offered Securities set forth in Schedule I hereto
opposite their names at a purchase price of 98.0% of the principal amount
thereof plus accrued interest, if any, from September 27, 1995 to the date of
payment and delivery.

     On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company agrees to sell
to the Purchasers the Additional Offered Securities, and the Purchasers shall
have a one-time right to purchase, severally and not jointly, up to $33,750,000

delivery. Additional Offered Securities may be purchased as provided in this
Section 3 solely for the purpose of covering over-allotments made in connection
with the offering of the Firm Offered Securities.  If any Additional Offered
Securities are to be purchased, each Purchaser agrees, severally and not
jointly, to purchase the number of Additional Offered Securities (subject to
such adjustments to eliminate fractional shares as the Manager shall determine)
that bears the same proportion to the total number of Additional Offered
Securities to be purchased as the number of Firm Offered Securities set forth in
Schedule I opposite the name of such Purchaser bears to the total number of Firm
Offered Securities.

     The Company agrees that without your prior written consent, it will not
offer, pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase, or otherwise transfer or dispose of, directly or indirectly, any
shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock, or enter into any swap or similar agreement that
transfers, in whole or in part, the economic risk of ownership of the Common
Stock for a period of 90 days after the date of this Agreement, other than (i)
the Offered Securities to be sold hereunder, (ii) the Underlying Securities,
(iii) options to purchase shares of Common Stock, shares of Common Stock issued
by the Company upon the exercise of such options and shares of Common Stock
issuable under the Company' s existing employee benefit plans, (iv) Common Stock
issuable upon redemption of the $40.00 Convertible Exchangeable Preferred
Shares, and (v) purchases of Common Stock pursuant to the Company's existing
stock purchase program.  The Company agrees to give notice to its directors and
executive officers promptly following the date hereof (but in no event later
than the Closing Date) of the restrictions imposed by the Board of Directors of
the Company pursuant to the minutes referred to in Section 4(f) below.  The

or solicit offers to buy or otherwise negotiate in respect of any security (as
defined in the


                                      -12-

Securities Act) which could be integrated with the sale of the Offered

Act of such Securities.

          (g)  Not to solicit any offer to buy or offer or sell the Offered
Securities 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 Section 4(2) of the
Securities Act.

          (h)  While any of the Securities remain "restricted securities" within
the meaning of the Securities Act, to make available, upon request, to any
seller of such Securities the information specified in Rule 144A(d) (4) under

          (j)  To use its best efforts to permit the Offered Securities to be

trading in the PORTAL Market.

          (k)  None of the Company, its Affiliates or any person acting on its
or their behalf (other than the Purchasers) will engage in any directed selling
efforts (as that term is defined in Regulation S) with respect to the Offered
Securities, and the Company and its Affiliates and each person acting on its or
their behalf (other than the Purchasers) will comply with the offering
restrictions of Regulation S.

          (l)   The Company will not resell any of the Securities.

     6.   OFFERING OF SECURITIES; RESTRICTIONS ON TRANSFER.

          (a)  Each Purchaser, severally and not jointly, represents and
warrants that such Purchaser is a qualified institutional buyer as defined in

jointly, agrees with the Company that (a) it will not solicit offers for, or

of Section 4(2) of the Securities Act and (b) it will solicit offers for such
Offered Securities only from, and will offer such Offered


                                      -13-

Securities only to, persons that it reasonably believes (A) in the case of
offers inside the United States, (i) to be QIBs or (ii) to be institutional

Securities Act ("institutional accredited investors") that, prior to their
purchase of the Offered Securities, deliver to such Purchaser a letter
containing the representations and agreements set forth in Annex A to the
Memorandum and (B) in the case of offers outside the United States, to be
persons other than U.S. persons ("foreign purchasers," which term shall include
dealers or other professional fiduciaries in the United States acting on a
discretionary basis for foreign beneficial owners (other than an estate or
trust)) that, in each case, in purchasing such Offered Securities are deemed to
have represented and agreed as provided in Exhibit D.

          (b)  Each Purchaser, severally and not jointly, represents, warrants,
and agrees with respect to offers and sales outside the United States that:

               (i)  it understands that no action has been or will be taken in
     any jurisdiction by such Purchaser that would permit a public offering of
     the Offered Securities, or possession or distribution of either Memorandum
     or any other offering or publicity material relating to the Offered
     Securities, in any country or jurisdiction where action for that purpose is
     required;

               (ii) such Purchaser will comply with all applicable laws and
     regulations in each jurisdiction in which it acquires, offers, sells or
     delivers Offered Securities or has in its possession or distributes either
     Memorandum or any such other material, in all cases at its own expense;

               (iii)     the Offered Securities have not been and will not be
     registered under the Securities Act and may not be offered or sold within
     the United States or to, or for the account or benefit of, U.S. persons
     except in accordance with Regulation S under the Securities Act or pursuant
     to another exemption from the registration requirements of the Securities
     Act;

               (iv) such Purchaser has offered the Offered Securities and will
     offer and sell the Offered Securities (A) as part of their distribution at
     any time and (B) otherwise until 40 days after the later of the
     commencement of the Offering and the Closing Date, only in accordance with
     Rule 903 of Regulation S.  Accordingly, neither such Purchaser, its
     Affiliates nor any persons acting on its or their behalf have engaged or
     will engage in any directed selling efforts (within the meaning of
     Regulation S) with respect to the Offered Securities, and any such
     Purchaser, its Affiliates and any such persons have


                                      -14-

<PAGE>

     complied and will comply with the offering restrictions requirement of
     Regulation S;

               (v)  such Purchaser has (1) not offered or sold and will not
     offer or sell any Offered Securities to persons in the United Kingdom
     except to persons whose ordinary activities involve them in acquiring,
     holding, managing or disposing of investments (as principal or agent) for
     the purposes of their businesses or otherwise in circumstances which have
     not required and will not result in an offer to the public in the United
     Kingdom within the meaning of the Public Offers of Securities Regulations
     1995 (the "Regulations"); (2) complied and will comply with all applicable
     provisions of the Financial Services Act 1986 and the Regulations with
     respect to anything done by it in relation to the Offered Securities in,
     from or otherwise involving the United Kingdom; and (3) only issued or
     passed on and will only issue or pass on to any person in the United
     Kingdom any document received by it in connection with the issue of the
     Offered Securities if that person is of a kind described in Article 11(d)
     of the Financial Services Act 1986 (Investment Advertisements) (Exemptions)
     Order 1995 or is a person to whom such document may otherwise lawfully be
     issued or passed on.

               (vi) such Purchaser understands that the Offered Securities have
     not been and will not be registered under the Securities and Exchange Law
     of Japan, and represents that it has not offered or sold, and agrees that
     it will not offer or sell, any Offered Securities, directly or indirectly
     in Japan or to or from 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 other applicable requirements
     of Japanese law; and

              (vii) such Purchaser agrees that, at or prior to confirmation of
     sales of the Offered Securities, it will have sent to each distributor,
     dealer or person receiving a selling concession, fee or other remuneration
     that purchases Offered Securities from it during the restricted period a
     confirmation or notice to substantially the following effect:

          The Securities covered hereby have not been registered under the U.S.
          Securities Act of 1933 (the "Securities Act") and may not be offered
          and sold within the United States or to, or for the account or benefit
          of, U.S. persons (i) as part of their distribution at any time or (ii)
          otherwise until 40 days after the later of the commencement of the
          offering and the closing date, except in either case in accordance
          with Regulation S (or


                                      -15-

<PAGE>

Rule 144A if available) under the Securities Act.  Terms used above have the
meaning given to them by Regulation S.

Terms used in this Section 6 have the meanings given to them by Regulation S.

     7.   INDEMNIFICATION AND CONTRIBUTION.

          (a)  The Company agrees to indemnify and hold harmless each Purchaser,
and each person, if any, who controls such Purchaser within the meaning of
either Section 15 of the Securities Act or Section 20 of the Exchange Act, or is
under common control with, or is controlled by, such Purchaser, from and against
any and all losses, claims, damages and liabilities (including, without
limitation, any legal or other expenses reasonably incurred by any Purchaser or
any such controlling of affiliated person in connection with defending or
investigating any such action or claim) caused by any untrue statement or
alleged untrue statement of a material fact contained in either Memorandum (as
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto), or caused by any omission or alleged omission to state
therein a material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading, except insofar as
such losses, claims, damages or liabilities are caused by any such untrue
statement or omission or alleged untrue statement or omission based upon
information relating to any Purchaser furnished to the Company in writing by
such Purchaser through you expressly for use therein.

          (b)  Each Purchaser agrees, severally and not jointly, to indemnify
and hold harmless the Company, its directors, its officers and each person, if
any, who controls the Company within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to such Purchaser, but only with reference
to information relating to such Purchaser furnished to the Company in writing by
such Purchaser through you expressly for use in either Memorandum or any
amendments or supplements thereto.

          (c)  In case any proceeding (including any governmental investigation)
shall be instituted involving any person in respect of which indemnity may be
sought pursuant to either paragraph (a) or (b) above, such person (the
"indemnified party") shall promptly notify the person against whom such
indemnity may be sought (the "indemnifying party") in writing and the
indemnifying party, upon request of the indemnified party, shall retain counsel
reasonably satisfactory to the indemnified party to represent the indemnified
party and any others the


                                      -16-

<PAGE>

indemnifying party may designate in such proceeding and shall pay the fees and
disbursements of such counsel related to such proceeding.  In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying party and the indemnified
party shall have mutually agreed to the retention of such counsel or (ii) the
named parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them.  It is understood that the indemnifying party
shall not, in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
(in addition to any local counsel) for all such indemnified parties and that all
such fees and expenses shall be reimbursed as they are incurred.  Such firm
shall be designated in writing by Morgan Stanley & Co. Incorporated in the case
of parties indemnified pursuant to paragraph (a) above and by the Company in the
case of parties indemnified pursuant to paragraph (b) above. The indemnifying
party shall not be liable for any settlement of any proceeding effected without
its written consent, but if settled with such consent or if there be a final
judgment for the plaintiff, the indemnifying party agrees to indemnify the
indemnified party from and against any loss or liability by reason of such
settlement or judgment.  Notwithstanding the foregoing sentence, if at any time
an indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel as contemplated by the second
and third sentences of this paragraph, the indemnifying party agrees that it
shall be liable for any settlement of any proceeding effected without its
written consent if (i) such settlement is entered into more than 30 days after
receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement.  No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement of any pending or threatened proceeding in respect of which any
indemnified party is or could have been a party and indemnity could have been
sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims
that are the subject matter of such proceeding.

          (d)  To the extent the indemnification provided for in paragraph (a)
or (b) of this Section 7 is unavailable to an indemnified party or insufficient
in respect of any losses, claims, damages or liabilities, then each indemnifying
party under such paragraph, in lieu of indemnifying such indemnified party
thereunder, shall contribute to the amount paid or payable by such indemnified
party as a result


                                      -17-

<PAGE>

of such losses, claims, damages or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company on the one
hand and the Purchasers on the other hand from the offering of such Offered
Securities or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Company on the one hand and the Purchasers on the other hand in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, as well as any other relevant equitable
considerations.  The relative benefits received by the Company on the one hand
and the Purchasers on the other hand in connection with the offering of such
Offered Securities shall be deemed to be in the same respective proportions as
the net proceeds from the offering of such Offered Securities (before deducting
expenses) received by the Company and the total discounts and commissions
received by the Purchasers in respect thereof, in each case as set forth in the
Final Memorandum, bear to the aggregate offering price of such Offered
Securities.  The relative fault of the Company on the one hand and of the
Purchasers on the other hand 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 Purchasers and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission.  The Purchasers' respective obligations to contribute
pursuant to this Section 7 are several in proportion to the respective principal
amount of Offered Securities they have purchased hereunder, and not joint.

          (e)  The Company and the Purchasers agree that it would not be just or
equitable if contribution pursuant to this Section 7 were determined by  PRO
RATA allocation (even if the Purchasers were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in paragraph (d) above.  The amount paid or
payable by an indemnified party as a result of the losses, claims, damages and
liabilities referred to in paragraph (d) above shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim.  Notwithstanding the provisions of this
Section 7, no Purchaser shall be required to contribute any amount in excess of
the amount by which the total price at which the Offered Securities resold by it
in the initial placement of such Offered Securities were offered to investors
exceeds the amount of any damages that such Purchaser has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission.  No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to


                                      -18-

<PAGE>

contribution from any person who was not guilty of such fraudulent
misrepresentation.  The indemnity and contribution provisions contained in this
Section 7 and the representations and warranties of the Company contained in
this Agreement shall remain operative and in full force and effect regardless of
(i) any termination of this Agreement, (ii) any investigation made by or on
behalf of the Purchasers or any person controlling the Purchasers or by or on
behalf of the Company, its officers or directors or any person controlling the
Company and (iii) acceptance of and payment for any of the Offered Securities.
The remedies provided for in this Section 7 are not exclusive and shall not
limit any rights or remedies which may otherwise be available to any indemnified
party at law or in equity.

     8.   TERMINATION.  This Agreement shall be subject to termination by notice
given by you to the Company, if (a) after the execution and delivery of this
Agreement and prior to the Closing Date or the Option Closing Date, as the case
may be, (i) trading generally shall have been suspended or materially limited on
or by, as the case may be, any of the New York Stock Exchange, the American
Stock Exchange, the National Association of Securities Dealers, Inc., the
Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the
Chicago Board of Trade, (ii) trading of any securities of the Company shall have
been suspended on any exchange or in any over-the-counter market, (iii) a
general moratorium on commercial banking activities in New York shall have been
declared by either Federal or New York State authorities or (iv) there shall
have occurred any outbreak or escalation of hostilities or any change in
financial markets or any calamity or crisis that, in your judgment, is material
and adverse and (b) in the case of any of the events specified in clauses (a)
(i) through (iv), such event singly or together with any other such event makes
it, in your judgment, impracticable to market the Offered Securities on the
terms and in the manner contemplated in the Final Memorandum.

     9.   MISCELLANEOUS.  If, on the Closing Date, or the Option Closing Date,
as the case may be, any one or more of the Purchasers shall fail or refuse to
purchase Offered Securities that it or they have agreed to purchase hereunder on
such date, and the aggregate principal amount of Offered Securities which such
defaulting Purchaser or Purchasers agreed but failed or refused to purchase is
not more than one-tenth of the aggregate principal amount of Offered Securities
to be purchased on such date, the other Purchasers shall be obligated severally
in the proportions that the principal amount of Firm Offered Securities set
forth opposite their respective names in Schedule I bears to the aggregate
principal amount of Firm Offered Securities set forth opposite the names of all
such non-defaulting Purchasers, or in such other proportions as you may specify,
to purchase the Offered Securities which such defaulting Purchaser or Purchasers
agreed but failed or refused to purchase on such


                                      -19-

<PAGE>

date; PROVIDED that in no event shall the principal amount of Offered Securities
that any Purchaser has agreed to purchase pursuant to Section 3 be increased
pursuant to this Section 9 by an amount in excess of one-ninth of such principal
amount of Offered Securities without the written consent of such Purchaser. If,
on the Closing Date or the Option Closing Date, as the case may be, any
Purchaser or Purchasers shall fail or refuse to purchase Offered Securities
which it or they have agreed to purchase hereunder on such date and the
aggregate principal amount of Offered Securities with respect to which such
default occurs is more than one-tenth of the aggregate principal amount of
Offered Securities to be purchased on such date and arrangements satisfactory to
you and the Company for the purchase of such Offered Securities are not made
within 36 hours after such default, this Agreement shall terminate without
liability on the part of any non-defaulting Purchaser or of the Company.  In any
such case either you or the Company shall have the right to postpone the Closing
Date, or the Option Closing Date, as the case may be, but in no event for longer
than seven days, in order that the required changes, if any, in the Final
Memorandum or in any other documents or arrangements may be effected.  Any
action taken under this paragraph shall not relieve any defaulting Purchaser
from liability in respect of any default of such Purchaser under this Agreement.

     This Agreement may be signed in any number of counterparts, each of which
shall be an original, with the same effect as if the signatures thereto and
hereto were upon the same instrument.

     If this Agreement shall be terminated by the Purchasers, or any of them,
because of any failure or refusal on the part of the Company to comply with the
terms or to fulfill any of the conditions of this Agreement, or if for any
reason the Company shall be unable to perform its obligations under this
Agreement, the Company will reimburse the Purchasers or such Purchasers as have
so terminated this Agreement with respect to themselves, severally, for all out-
of-pocket expenses (including the fees and disbursements of their counsel)
reasonably incurred by such Purchasers in connection with this Agreement or the
offering contemplated hereunder.

     This Agreement shall be governed by and construed in accordance with the
internal laws of the State of New York.

     The headings of the sections of this Agreement have been inserted for
convenience of reference only and shall not be deemed a part of this Agreement.

                           OPINION OF LATHAM & WATKINS

     and is a valid and binding agreement of the Company enforceable in
     accordance with its terms except as (x) the enforceability thereof may be
     limited by bankruptcy, insolvency or similar laws affecting creditors'
     rights generally and (y) rights of acceleration, if applicable, and the
     availability of equitable remedies may be limited by equitable principles
     of general applicability.

          4.   The Registration Rights Agreement has been duly authorized,

     to register the Offered Securities or the Underlying Securities under the
     Securities Act of 1933 or to qualify the Indenture under the Trust
     Indenture Act of 1939, it being understood that no opinion is expressed as
     to any subsequent resale of any Offered Security or Share.

          With respect to paragraph 11 above, counsel may state that his opinion
and belief are based upon his participation in the preparation of the Final
Memorandum (and any amendments or supplements thereto) and documents
incorporated therein by reference and review and discussion of the contents

       the expense of the Company, shall cause notice of the proposed payment
       of such Defaulted Interest and the special record date therefor to be
       mailed, first-class postage prepaid, to each Noteholder as of such
       special record date at his address as it appears in the Note register,
       not less than ten (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 (2).

          (2)  The Company may make payment of any Defaulted Interest in any
       other lawful manner not inconsistent with the requirements of any
       securities exchange and automated quotation system on which the Notes may
       be listed or designated for issuance, and upon such notice as may be
       required by such exchange and automated quotation system, 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.

     Section 2.4    EXECUTION OF NOTES.  The Notes shall be signed in the name
and on behalf of the Company by the facsimile signature of its President, any
Executive or Senior Vice President or any Vice President (whether or not
designated by a number or numbers or word or words added before or after the
title "Vice President") and attested by the facsimile signature of its Secretary
or any of its Assistant Secretaries (which may be printed, engraved or otherwise
reproduced thereon, by facsimile or otherwise).  Only such Notes as shall bear
thereon a certificate of authentication substantially in the form set forth on
the form of Note attached as Exhibit A hereto, manually executed by the Trustee
(or an authenticating agent appointed by the Trustee as provided by Section
16.11), 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


                                      -11-
<PAGE>

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.

       Section 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
     a register (the register maintained in such office and in any other office
     or agency of the Company designated pursuant to Section 5.2 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.  The
     Note register shall be in written form or in any form capable of being
     converted into written form within a reasonably prompt 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 in accordance with Section 5.2.

          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 deliver, 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 this Indenture.

          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 office or agency maintained by the Company pursuant
     to Section 5.2.  Whenever any Notes are so surrendered for exchange, the
     Company shall execute, and the Trustee shall authenticate and deliver, the
     Notes which the Noteholder making the exchange is entitled to receive
     bearing registration numbers not contemporaneously outstanding.

          All Notes issued upon any registration of 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.

          All Notes presented or surrendered for registration of transfer or for
     exchange, redemption or conversion shall (if so required by the Company or
     the Note registrar) be duly endorsed, or be accompanied by a written
     instrument or


                                      -12-
<PAGE>

     instruments of transfer in form satisfactory to the Company, and the Notes
     shall be duly executed by the Noteholder thereof or his attorney duly
     authorized in writing.

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

          Neither the Company nor the Trustee nor any Note registrar or any
     Company-registrar shall be required to exchange or register a transfer of
     (a) any Notes for a period of fifteen (15) days next preceding any
     selection of Notes to be redeemed or (b) any Notes or portions thereof
     selected or called for redemption pursuant to Article III or (c) any Notes
     or portion thereof surrendered for conversion pursuant to Article XV.

          (b)  So long as the Notes are eligible for book-entry settlement with
     the Depositary, unless otherwise required by law, all Notes to be traded on
     the PORTAL Market or to a Person who is not a U.S. Person (as defined in
     Regulation S) who is acquiring the Note in an offshore transaction (a "Non-
     U.S. Person") in accordance with Regulation S shall be represented by a
     Note in global form registered in the name of the Depositary or the nominee
     of the Depositary. The transfer and exchange of beneficial interests in
     such Note in global form, which does not involve the issuance of a Note in
     definitive form, shall be effected through the Depositary, in accordance
     with this Indenture (including the restrictions on transfer set forth
     herein) and the procedures of the Depositary therefor.

          At any time at the request of the beneficial holder of an interest in
     a Note in global form to obtain a Note in definitive form, 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 Custodian and Depositary
     for the issuance thereof.  Upon receipt of any such request, the Trustee,
     or the Custodian at the direction of the Trustee, will cause, in accordance
     with the standing instructions and procedures existing between the
     Depositary and the Custodian, the aggregate principal amount of the Note in
     global form to be reduced by the principal amount of the definitive Note
     issued upon such request to such beneficial holder and, following such
     reduction, the Company will execute and the Trustee will authenticate and
     deliver to such beneficial holder (or its nominee) a definitive 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 Note in global form which
     cannot be effected through book-entry settlement must be effected by the
     delivery to the


                                      -13-
<PAGE>

     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 Note
     registrar in accordance with the transfer restrictions set forth herein.
     With respect to any such transfer, the Trustee, or the Custodian at the
     direction of the Trustee, will cause, in accordance with the standing
     instructions and procedures existing between the Depositary and the
     Custodian, the aggregate principal amount of the Note in global form to be
     reduced by the principal amount of the beneficial interest in the Note in
     global form being transferred and, following such reduction, the Company
     will execute and the Trustee will authenticate and deliver to the
     transferee (or such transferee's nominee, as the case may be), a Note or
     Notes in the appropriate aggregate principal amount in the name of such
     transferee (or its nominee) and bearing such restrictive legends as may be
     required by this Indenture.

          (c)  So long as the Notes are eligible for book-entry settlement, or
     unless otherwise required by law, upon any transfer of a definitive Note to
     a QIB in accordance with Rule 144A or a Non-U.S. Person in accordance with
     Regulation S, and upon receipt of the definitive Note or Notes being so
     transferred, together with a certification from the transferor that the
     transferee is a QIB or a Non-U.S. Person (or other evidence satisfactory to
     the Trustee), the Trustee shall make, or direct the Custodian to make, an
     endorsement on the Note in global form to reflect an increase in the
     aggregate principal amount of the Notes represented by the Note in global
     form, and 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 Note
     in global form to be increased accordingly; PROVIDED that no definitive
     Note, or portion thereof, in respect of which the Company or an Affiliate
     of the Company held any beneficial interest shall be included in such Note
     in global form until such definitive Note is freely tradable in accordance
     with Rule 144(k); PROVIDED FURTHER that the Trustee shall issue Notes in
     definitive form upon any transfer of a beneficial interest in the Note
     in global form to the Company or an Affiliate of the Company.

          Any Note in global form 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 other market developed for
     trading of securities pursuant to Rule 144A or Regulation S under the
     Securities Act or required to comply with any applicable law or any
     regulation thereunder or with the rules and regulations of any securities
     exchange or automated quotation system 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.


                                      -14-
<PAGE>

          (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) (including those set forth in the legend set forth below) unless
     such restrictions on transfer shall be waived by written consent of the
     Company, and the holder of each such Restricted Note, by such Noteholder's
     acceptance thereof, agrees to be bound by all such restrictions on
     transfer.  As used in Sections 2.5(d) and 2.5(e), the term "transfer"
     encompasses any sale, pledge, transfer or other disposition whatsoever of
     any Restricted Security.

          Until three (3) years after the original issuance date of any Note,
     any certificate evidencing such Note (and all securities issued in exchange
     therefor or substitution 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 in writing, with written
     notice thereof to the Trustee:

          THE NOTE EVIDENCED HEREBY HAS NOT BEEN AND WILL NOT BE
          REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED
          (THE "SECURITIES ACT") OR ANY STATE SECURITIES LAWS, AND,
          ACCORDINGLY, 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 ITS
          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) ("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 WITHIN THREE YEARS
          AFTER THE ORIGINAL ISSUANCE OF THE NOTE EVIDENCED HEREBY
          RESELL OR OTHERWISE TRANSFER THE NOTE EVIDENCED HEREBY OR
          THE COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH NOTE
          EXCEPT (A) TO NATIONAL SEMICONDUCTOR CORPORATION OR ANY
          SUBSIDIARY THEREOF, (B) INSIDE THE UNITED

          STATES TO A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH
          RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE UNITED
          STATES TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR
          TO SUCH TRANSFER, FURNISHES TO THE FIRST NATIONAL BANK OF
          BOSTON, AS TRUSTEE (OR A SUCCESSOR TRUSTEE, AS APPLICABLE),
          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 THE COMPANY), (D) OUTSIDE THE UNITED STATES IN
          COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT, OR (E)
          PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE
          144 UNDER THE SECURITIES ACT (IF AVAILABLE); 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 WITHIN THREE YEARS AFTER THE
          ORIGINAL ISSUANCE OF SUCH NOTE, 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 FIRST NATIONAL BANK OF BOSTON, AS TRUSTEE (OR A
          SUCCESSOR TRUSTEE, AS APPLICABLE). IF THE PROPOSED
          TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR , THE
          HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE FIRST
          NATIONAL BANK OF BOSTON, AS TRUSTEE (OR A SUCCESSOR TRUSTEE,
          AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS OR OTHER
          INFORMATION AS IT 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 ANY TRANSFER OF THE NOTE EVIDENCED HEREBY AFTER
          THE EXPIRATION OF THREE YEARS FROM THE ORIGINAL ISSUANCE OF
          THE NOTE EVIDENCED HEREBY. AS


                                      -16-
<PAGE>

          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 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 Note in global form may not
     be transferred as a whole or in part 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 Notes in global form. Initially,
     the global Note shall be issued to the Depositary, registered in the name
     of Cede & Co., as the nominee of the Depositary, and deposited with the
     Custodian for Cede & Co.

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

          If a definitive Note is issued in exchange for any portion of a Note
     in global form after the close of business at the office or agency where
     such exchange occurs on any record date and before the opening of business
     at such office or agency on the next succeeding interest payment date,
     interest will not be payable on such interest payment date in respect of
     such Note, but will be payable on such interest payment date only to the
     person to whom interest in respect of such portion of such Note in global
     form is payable in accordance with the provisions of this Indenture.


                                      -17-
<PAGE>

          Definitive Notes issued in exchange for all or a part of a Note in
     global form pursuant to this Section 2.5 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
     deliver such definitive Notes to the persons in whose names such definitive
     Notes are so registered.

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

          (e) Until three (3) years after the original issuance date of any
     Note, any stock certificate representing Common Stock issued upon
     conversion of such Note shall bear a legend in substantially the following
     form, unless such Common Stock has been sold pursuant to a registration
     statement that has been declared effective under the Securities Act (and
     which continues to be effective at the time of such transfer) or such
     Common Stock has been issued upon conversion of Notes that have been
     transferred pursuant to a registration statement that has been declared
     effective under the Securities Act, or unless otherwise agreed by the
     Company in writing with written notice thereof to the transfer agent:

          THE COMMON STOCK EVIDENCED HEREBY HAS NOT BEEN AND WILL NOT
          BE REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS
          AMENDED (THE "SECURITIES ACT") OR ANY STATE SECURITIES LAWS,
          AND, ACCORDINGLY, 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. THE
          HOLDER HEREOF AGREES THAT UNTIL THE EXPIRATION OF THREE
          YEARS AFTER THE ORIGINAL ISSUANCE OF THE NOTE UPON THE
          CONVERSION OF

          CORPORATION OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED
          STATES TO A "QUALIFIED INSTITUTIONAL BUYER" (AS DEFINED IN
          RULE 144A UNDER THE SECURITIES ACT) IN COMPLIANCE WITH RULE

          ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(A)(1), (2), (3)
          OR (7) UNDER THE SECURITIES ACT) THAT, PRIOR TO SUCH
          TRANSFER, FURNISHES TO THE FIRST NATIONAL BANK OF BOSTON, AS
          TRANSFER AGENT (OR A SUCCESSOR TRANSFER AGENT, AS
          APPLICABLE), A SIGNED LETTER CONTAINING CERTAIN
          REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS
          ON TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY (THE FORM
          OF WHICH LETTER CAN BE OBTAINED FROM SUCH TRANSFER AGENT (OR
          A SUCCESSOR TRANSFER AGENT, AS APPLICABLE)), (D) OUTSIDE THE
          UNITED STATES IN COMPLIANCE WITH RULE 904 UNDER THE

          REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT
          (IF AVAILABLE), OR (F) PURSUANT TO A REGISTRATION STATEMENT
          WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE SECURITIES ACT
          (AND WHICH CONTINUES TO BE EFFECTIVE AT THE TIME OF SUCH
          TRANSFER); (2) PRIOR TO SUCH TRANSFER (OTHER THAN A TRANSFER
          PURSUANT TO CLAUSE 1(F) ABOVE), IT WILL FURNISH THE FIRST
          NATIONAL BANK OF BOSTON, AS TRANSFER AGENT (OR A SUCCESSOR
          TRANSFER AGENT, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL
          OPINIONS OR OTHER INFORMATION AS IT 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 AND (3) IT

          TO CLAUSE 1(F) ABOVE) A NOTICE SUBSTANTIALLY TO THE EFFECT
          OF THIS LEGEND. THIS LEGEND WILL BE REMOVED UPON THE EARLIER
          OF THE TRANSFER OF THE COMMON STOCK EVIDENCED HEREBY
          PURSUANT TO CLAUSE 1(F) ABOVE OR UPON ANY TRANSFER OF THE
          COMMON STOCK EVIDENCED HEREBY AFTER THE EXPIRATION OF THREE
          YEARS FROM THE ORIGINAL ISSUANCE OF THE NOTE UPON THE
          CONVERSION OF WHICH THE COMMON STOCK EVIDENCED HEREBY WAS
          ISSUED OR UPON THE EARLIER SATISFACTION OF THE FIRST
          NATIONAL BANK OF BOSTON, AS TRANSFER AGENT (OR A SUCCESSOR
          TRANSFER AGENT, AS APPLICABLE), THAT THE COMMON STOCK HAS
          BEEN OR IS BEING OFFERED AND SOLD IN COMPLIANCE WITH RULE
          904 UNDER THE SECURITIES ACT. 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 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 number of
     shares of Common Stock, which shall not bear the restrictive legend
     required by this Section 2.5(e).

          (f) Any certificate evidencing a Note that has been transferred to an
     Affiliate of the Company within three years after the original issuance
     date of the Note, as evidenced by a notation on the Assignment Form for
     such transfer or in the representation letter delivered in respect thereof,
     shall, until three years after the last date on which the Company or any
     Affiliate of the Company was an owner of such Note, bear a legend in
     substantially the following form, unless otherwise agreed by the Company
     (with written 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"), AND, ACCORDINGLY, 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 ITS ACQUISITION HEREOF, THE HOLDER AGREES (1) THAT IT
          WILL NOT RESELL OR OTHERWISE TRANSFER THE NOTE EVIDENCED
          HEREBY OR THE


                                      -20-
<PAGE>

          COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH NOTE EXCEPT
          (A) TO NATIONAL SEMICONDUCTOR CORPORATION OR ANY SUBSIDIARY
          THEREOF, (B) IN A TRANSACTION REGISTERED UNDER THE
          SECURITIES ACT OR (C) PURSUANT TO THE EXEMPTION FROM
          REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT
          (IF AVAILABLE) AND (2) THAT IT WILL DELIVER TO EACH PERSON
          TO WHOM THE NOTE EVIDENCED HEREBY IS TRANSFERRED A NOTICE
          SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. THIS LEGEND
          SHALL BE REMOVED UPON THE TRANSFER OF THE NOTE EVIDENCED
          HEREBY OR THE COMMON STOCK ISSUABLE UPON CONVERSION OF SUCH
          NOTE PURSUANT TO THE IMMEDIATELY PRECEDING SENTENCE. IF THE
          PROPOSED TRANSFER IS PURSUANT TO THE EXEMPTION FROM
          REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT,
          THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE
          FIRST NATIONAL BANK OF BOSTON, AS TRUSTEE (OR A SUCCESSOR
          TRUSTEE, AS APPLICABLE), SUCH CERTIFICATIONS, LEGAL OPINIONS
          OR OTHER INFORMATION AS THE COMPANY 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. 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 stock certificate representing Common Stock issued upon conversion
     of such Note shall also bear a legend in substantially the form indicated
     above, unless otherwise agreed by the Company (with written notice thereof
     to the Trustee).

          (g) Notwithstanding any provision of Section 2.5 to the contrary, in
     the event Rule 144(k) as promulgated under the Securities Act (or any
     successor rule) is amended to shorten the three-year period under Rule
     144(k) (or the corresponding period under any successor rule), from and
     after receipt by the Trustee of the Officers' Certificate and Opinion of
     Counsel provided for in this Section 2.5(g), (i) the references in the
     first sentence of the second paragraph of Section 2.5(d) to "three (3)
     years" and in the restrictive legend set forth in such paragraph
     to "THREE YEARS" shall be deemed for all purposes hereof to be references
     to such shorter period, (ii) the references in the first paragraph of
     Section 2.5(e) to "three (3) years" and in the restrictive legend set forth
     in such paragraph

                                      -21-
<PAGE>

     to "THREE YEARS" shall be deemed for all purposes hereof
     to be references to such shorter period and (iii) all corresponding
     references in the Notes and the restrictive legends thereon shall be deemed
     for all purposes hereof to be references to such shorter period, provided
     that such changes shall not become effective if they are otherwise
     prohibited by, or would otherwise cause a violation of, the then-applicable
     federal securities laws. As soon as practicable after the Company has
     knowledge of the effectiveness of any such amendment, the Company shall
     provide to the Trustee an Officers' Certificate and Opinion of Counsel
     informing the Trustee of the effectiveness of such amendment and the
     effectiveness of the foregoing changes to Sections 2.5(d) and 2.5(e) and
     the Notes. This Section 2.5(g) shall apply to successive amendments to Rule
     144(k) (or any successor rule) shortening the holding period thereunder.

     Section 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 deliver, 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.  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 for 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 which 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 for 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


                                      -22-
<PAGE>

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
by virtue of the fact that any Note 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 found at any time, 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.

     Section 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 the written request of the Company,
authenticate and deliver temporary Notes (printed or lithographed).  Temporary
Notes shall be issuable in any authorized denomination, and 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 will 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 Note in global form) may be surrendered in exchange
therefor, at each office or agency maintained by the Company pursuant to Section
5.2 and the Trustee or such authenticating agent shall authenticate and deliver
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.

     Section 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.  The Trustee shall destroy canceled
Notes (unless the Company directs it to do otherwise) and, after such


                                      -23-
<PAGE>

destruction, shall, if requested by the Company, deliver a certificate of such
destruction 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.


                                   ARTICLE III

                               REDEMPTION OF NOTES

       Section 3.1    REDEMPTION PRICES.  The Company may not redeem the Notes
prior to October 3, 1998.  On or after such date, the Company may, at its
option, redeem all or from time to time any part of the Notes on any date prior
to maturity, upon notice as set forth in Section 3.2, and at the optional
redemption prices set forth in the form of Note attached as Exhibit A hereto,
together with accrued interest to, but excluding, the date fixed for redemption.

     Section 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 it or, at its request, the Trustee in the name of and at the
expense of the Company, shall 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 written notice, and
written 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 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 will be made upon presentation and surrender of such Notes, that
interest accrued to the date fixed for redemption will be paid as specified in
said notice, and that on and after said date interest thereon or on the portion
thereof to be redeemed will 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 will 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


                                      -24-
<PAGE>

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

       On or prior to the redemption date specified in the notice of redemption
given as provided in this Section 3.2, the Company will 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 5.4)
an amount of money sufficient to redeem on the redemption date all the Notes (or
portions thereof) so called for redemption (other than those theretofore
surrendered for conversion into Common Stock) at the appropriate redemption
price, together with accrued interest to, but excluding, the date fixed for
redemption; PROVIDED that if such payment is made on the redemption date it must
be received by the Trustee or paying agent, as the case may be, by 10:00 a.m.
New York City time, on such date.  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 will give the Trustee written notice in the form of an Officers'
Certificate not fewer than forty-five (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 (but need not) treat as outstanding any Notes surrendered for conversion
during the period of fifteen (15) days next preceding the mailing of a notice of
redemption and may (but 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.

       Section 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 (but
excluding) date and at the place or places stated in such notice at the
applicable redemption price, together with interest accrued to (but excluding)
the date fixed for redemption, and on and after said date


                                      -25-
<PAGE>

(unless the Company shall default in the payment of such Notes at the redemption
price, together with interest 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 8.5 and 13.4, 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 to (but excluding) 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 (but excluding) the date fixed for redemption; PROVIDED that, if the
applicable redemption date is an interest payment date, the semi-annual payment
of interest becoming due on such date 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 deliver 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.

       Notwithstanding the foregoing, the Trustee shall not redeem any Notes or
mail any notice of optional redemption during the continuance of a default in
payment of interest or premium on the Notes or of any Event of Default of which,
in the case of any Event of Default other than under Sections 7.1(a) or 7.1(b),
a Responsible Officer of the Trustee has knowledge.  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.

       Section 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 paying to the Trustee in
trust for the Noteholders, on or before the date fixed for redemption, an amount
not less than the applicable redemption price, together with interest accrued to
(but excluding) 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 (but excluding) 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 will be filed
with the Trustee prior to the date fixed for redemption, any Notes not duly
surrendered for conversion by the holders


                                      -26-
<PAGE>

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 XV) surrendered
by such purchasers for conversion, all as of immediately prior to the close of
business on the date fixed for redemption (and the right to convert any such
Notes shall be 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 to which the
Trustee has not consented in writing, 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.

       Section 3.5    REDEMPTION AT OPTION OF HOLDERS.

          (a) If there shall occur a Fundamental Change, then each Noteholder
     shall have the right, at such holder's option, to require the Company to
     redeem all of such holder's Notes, or any portion thereof that is an
     integral multiple of $1,000 principal amount, on the date (the "Repurchase
     Date") that is 30 days after the date of the Company Notice (as defined in
     Section 3.5(b) below) of such Fundamental Change (or, if such 30th day is
     not a Business Day, the next succeeding Business Day). Such repayment shall
     be made at the following prices (expressed as percentages of the principal
     amount) in the event of a Fundamental Change occurring during the 12-month
     period beginning August 15:

<TABLE>
<CAPTION>

          Year        Percentage             Year           Percentage
    --------------    ----------          ----------        ----------
    <S>               <C>                 <C>               <C>
    1995 . . . . .     106.500%              1999            102.786%
    1996 . . . . .     105.571               2000            101.857

    1998 . . . . .     103.714
</TABLE>

and 100% at November 1, 2002; PROVIDED that if the Applicable Price with respect
to the Fundamental Change is less than the Reference Market Price, the Company
shall redeem such Notes at a price equal to the foregoing redemption price
multiplied by the fraction obtained by dividing the Applicable Price by the
Reference Market Price; PROVIDED that if such repayment date is April 1 or


                                      -27-
<PAGE>

October 1, then the interest payable on such date shall be paid to the holder of
record of the Note on the next preceding March 15 or September 15.  In each
case, the Company shall also pay to such holders accrued interest to, but
excluding, the Repurchase Date on the redeemed Notes.

     Upon presentation of any Note redeemed in part only, the Company shall
execute and the Trustee shall authenticate and deliver 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.

     (b)  On or before the tenth day after the occurrence of a Fundamental
Change, the Company, or, at its request (which must be received by the Trustee
at least five Business Days prior to the date the Trustee is requested to give
notice as described below), the Trustee in the name of and at the expense of the
Company, shall mail or cause to be mailed to all holders of record on the date
of the Fundamental Change a notice (the "Company Notice") of the occurrence of
such Fundamental Change and of the redemption right at the option of the holders
arising as a result thereof.  Such notice shall be mailed in the manner and with
the effect set forth in the first paragraph of Section 3.2.  The Company shall
also deliver a copy of the Company Notice to the Trustee at such time as it is
mailed to Noteholders.

     Each Company Notice shall specify the circumstances constituting the
Fundamental Change, the Repurchase Date, the price at which the Company shall be
obligated to redeem Notes, the latest time on the Repurchase Date by which the
holder must exercise the redemption right (the "Fundamental Change Expiration
Time"), that the holder shall have the right to withdraw any Notes surrendered
prior to the Fundamental Change Expiration Time, a description of the procedure
which a Noteholder must follow to exercise such redemption right and to withdraw
any surrendered Notes, the place or places where the holder is to surrender such
holder's Notes, and the amount of interest accrued on each Note to the
Repurchase Date.

     No failure of the Company to give the foregoing notices and no defect
therein shall limit the Noteholders' redemption rights or affect the validity of
the proceedings for the repurchase of the Notes pursuant to this Section 3.5.

     (c)  For a Note to be so repaid at the option of the holder, the Company
must receive 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, such Note with the form entitled "Option to
Elect Repayment Upon A Fundamental Change" on the reverse thereof duly
completed, together with such Notes duly endorsed for transfer, on or before the
Fundamental


                                      -28-
<PAGE>

Change Expiration Time.  All questions as to the validity, eligibility
(including time of receipt) and acceptance of any Note for repayment shall be
determined by the Company, whose determination shall be final and binding absent
manifest error.

     (d)  On or prior to the Repurchase Date, the Company will 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
5.4) an amount of money sufficient to repay on the Repurchase Date all the Notes
to be repaid on such date at the appropriate redemption price, together with
accrued interest to (but excluding) the Repurchase Date; provided that if such
payment is made on the Repurchase Date it must be received by the Trustee or
paying agent, as the case may be, by 10:00 a.m. New York City time, on such
date.  Payment for Notes surrendered for redemption (and not withdrawn) prior to
the Fundamental Change Expiration Time will be made promptly (but in no event
more than three Business Days) following the Repurchase Date by mailing checks
for the amount payable to the holders of such Notes entitled thereto as they
shall appear on the registry books of the Company.


                                   ARTICLE IV

                             SUBORDINATION OF NOTES

     Section 4.1    AGREEMENT OF SUBORDINATION.  The Company covenants and
agrees, and each holder of Notes issued hereunder by his acceptance thereof
likewise covenants and agrees, that all Notes shall be issued subject to the
provisions of this Article IV; and each Person holding any Note, whether upon
original issue or upon transfer, assignment or exchange thereof, accepts and
agrees to be bound by such provisions.

     The payment of the principal of, premium, if any, and interest on all Notes
(including, but not limited to, the redemption price with respect to the Notes
to be called for redemption in accordance with Section 3.2 or submitted for
redemption in accordance with Section 3.5, as the case may be, as provided in
the Indenture) issued hereunder shall, to the extent and in the manner
hereinafter set forth, be subordinated and subject in right of payment to the
prior payment in full of all Senior Indebtedness, whether outstanding at the
date of this Indenture or thereafter incurred.

     No provision of this Article IV shall prevent the occurrence of any default
or Event of Default hereunder.

     Section 4.2    PAYMENTS TO NOTEHOLDERS.  In the event and during the
continuation of any default in the payment of principal, premium, interest or
any other payment due on any Senior Indebtedness (or, in the case of Senior
Indebtedness for which there is a period


                                      -29-
<PAGE>

of grace, in the event of such a default that continues beyond the period of
grace, if any, specified in the instrument or lease evidencing such Senior
Indebtedness), then, unless and until such default shall have been cured or
waived or shall have ceased to exist, no payment shall be made by the Company
with respect to the principal of, or premium, if any, or interest on the Notes
(including, but not limited to, the redemption price with respect to the Notes
to be called for redemption in accordance with Section 3.2 or submitted for
redemption in accordance with Section 3.5, as the case may be, as provided in
the Indenture) except payments made pursuant to Article XIII from monies
deposited with the Trustee pursuant thereto prior to the happening of such
default.

     Upon any payment by the Company, or distribution of assets of the Company
of any kind or character, whether in cash, property or securities, to creditors
upon any dissolution or winding-up or liquidation or reorganization of the
Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due or to become due upon all
Senior Indebtedness shall first be paid in full in money or money's worth, or
payment thereof provided for in money or money's worth, before any payment is
made on account of the principal (and premium, if any) or interest on the Notes
(except payments made pursuant to Article XIII from monies deposited with the
Trustee pursuant thereto prior to the happening of such dissolution, winding-up,
liquidation or reorganization); and upon any such dissolution or winding-up or
liquidation or reorganization of the Company or bankruptcy, insolvency,
receivership or other proceeding, any payment by the Company, or distribution of
assets of the Company of any kind or character, whether in cash, property or
securities, to which the holders of the Notes or the Trustee would be entitled,
except for the provision of this Article IV, shall (except as aforesaid) be paid
by the Company or by any receiver, trustee in bankruptcy, liquidating trustee,
agent or other Person making such payment or distribution, or by the holders of
the Notes or by the Trustee under this Indenture if received by them or it,
directly to the holders of Senior Indebtedness (pro rata to such holders on the
basis of the respective amounts of Senior Indebtedness held by such holders, or
as otherwise required by law or a court order) or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any Senior Indebtedness may have been issued,
as their respective interests may appear, to the extent necessary to pay all
Senior Indebtedness in full, in money or money's worth, after giving effect to
any concurrent payment or distribution to or for the holders of Senior
Indebtedness, before any payment or distribution is made to the holders of the
Notes or to the Trustee.

     In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities (including, without limitation, by way of setoff or
otherwise), prohibited by the foregoing, shall be received by the Trustee or the
holders of the Notes before all Senior Indebtedness is paid in full in money or
money's worth, or provision is made for such payment in money or money's worth
in accordance with its terms, such payment or distribution shall be held


                                       30
<PAGE>

in trust for the benefit of and shall be paid over or delivered to the holders
of Senior Indebtedness or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing any Senior Indebtedness may have been issued, as their respective
interests may appear, as calculated by the Company, for application to the
payment of all Senior Indebtedness remaining unpaid to the extent necessary to
pay all Senior Indebtedness in full in money or money's worth, after giving
effect to any concurrent payment or distribution to or for the holders of such
Senior Indebtedness.

       For purposes of this Article IV, the words, "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article IV with respect
to the Notes to the payment of all Senior Indebtedness which may at the time be
outstanding; PROVIDED that (i) the Senior Indebtedness is assumed by the new
corporation, if any, resulting from any reorganization or readjustment, and (ii)
the rights of the holders of Senior Indebtedness (other than leases which are
not assumed by the Company or the new corporation, as the case may be) are not,
without the consent of such holders, altered by such reorganization or
readjustment.  The consolidation of the Company with, or the merger of the
Company into, another corporation or the liquidation or dissolution of the
Company following the conveyance or transfer of its property as an entirety, or
substantially as an entirety, to another corporation upon the terms and
conditions provided for in Article XII shall not be deemed a dissolution,
winding-up, liquidation or reorganization for the purposes of this Section 4.2
if such other corporation shall, as a part of such consolidation, merger,
conveyance or transfer, comply with the conditions stated in Article XII.
Nothing in this Section 4.2 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 8.6.  This Section 4.2 shall be subject to
the further provisions of Section 4.5.

       Section 4.3    SUBROGATION OF NOTES.  Subject to the payment in full of
all Senior Indebtedness, the rights of the holders of the Notes shall be
subrogated to the extent of the payments or distributions made to the holders of
such Senior Indebtedness pursuant to the provisions of this Article IV (equally
and ratably with the holders of all indebtedness of the Company which by its
express terms is subordinated to other indebtedness of the Company to
substantially the same extent as the Notes are subordinated and is entitled to
like rights of subrogation) to the rights of the holders of Senior Indebtedness
to receive payments or distributions of cash, property or securities of the
Company applicable to the Senior Indebtedness until the principal of (and
premium, if any) and interest on the Notes shall be paid in full; and, for the
purposes of such subrogation, no payments or distributions to the holders of the
Senior Indebtedness of any cash, property or securities to which the holders of
the Notes or the Trustee would be entitled except for the provisions of this
Article IV, and no payment over pursuant to the provisions of this Article IV,
to or for the benefit of the holders of Senior Indebtedness by holders of the


                                      -31-
<PAGE>

Notes or the Trustee, shall, as between the Company, its creditors other than
holders of Senior Indebtedness, and the holders of the Notes, be deemed to be a
payment by the Company to or on account of the Senior Indebtedness; and no
payments or distributions of cash, property or securities to or for the benefit
of the holders of the Notes pursuant to the subrogation provisions of this
Article IV, which would otherwise have been paid to the holders of Senior
Indebtedness shall be deemed to be a payment by the Company to or for the
account of the Notes.  It is understood that the provisions of this Article IV
are and are intended solely for the purposes of defining the relative rights of
the holders of the Notes, on the one hand, and the holders of the Senior
Indebtedness, on the other hand.

       Nothing contained in this Article IV or elsewhere in this Indenture or in
the Notes is intended to or shall impair, as among the Company, its creditors
other than the holders of Senior Indebtedness, and the holders of the Notes, the
obligation of the Company, which is absolute and unconditional, to pay to the
holders of the Notes the principal of (and premium, if any) and interest on the
Notes as and when the same shall become due and payable in accordance with their
terms, or is intended to or shall affect the relative rights of the holders of
the Notes and creditors of the Company other than the holders of the Senior
Indebtedness, nor shall anything herein or therein prevent the Trustee or the
holder of any Note from exercising all remedies otherwise permitted by
applicable law upon default under this Indenture, subject to the rights, if any,
under this Article IV of the holders of Senior Indebtedness in respect of cash,
property or securities of the Company received upon the exercise of any such
remedy.

       Upon any payment or distribution of assets of the Company referred to in
this Article IV, the Trustee, subject to the provisions of Section 8.1, and the
holders of the Notes shall be entitled to rely upon any order or decree made by
any court of competent jurisdiction in which such bankruptcy, dissolution,
winding-up, liquidation or reorganization proceedings are pending, or a
certificate of the receiver, trustee in bankruptcy, liquidating trustee, agent
or other person making such payment or distribution, delivered to the Trustee or
to the holders of the Notes, 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 and all other facts pertinent thereto or to this Article IV.


       Section 4.4    AUTHORIZATION BY NOTEHOLDERS.  Each holder of a Note by
his acceptance thereof authorizes and directs the Trustee in his behalf to take
such action as may be necessary or appropriate to effectuate the subordination
provided in this Article IV and appoints the Trustee his attorney-in-fact for
any and all such purposes.

       Section 4.5    NOTICE TO TRUSTEE.  The Company shall give prompt written
notice in the form of an Officers' Certificate to a Responsible Officer of the
Trustee and to any paying agent of any fact known to the Company which would
prohibit the making of any payment of monies to or by the Trustee or any paying
agent in respect of the Notes


                                      -32-
<PAGE>

pursuant to the provisions of this Article IV.  Notwithstanding the provisions
of this Article IV or any other provision of this Indenture, the Trustee shall
not be charged with knowledge of the existence of any facts which would prohibit
the making of any payment of monies to or by the Trustee in respect of the Notes
pursuant to the provisions of this Article IV, unless and until a Responsible
Officer of the Trustee shall have received written notice thereof at the
Corporate Trust Office from the Company (in the form of an Officers'
Certificate) or a holder or holders of Senior Indebtedness or from any trustee
thereof; and before the receipt of any such written notice, the Trustee, subject
to the provisions of Section 8.1, shall be entitled in all respects to assume
that no such facts exist; PROVIDED that if on a date not fewer than two Business
Days prior to the date upon which by the terms hereof any such monies may become
payable for any purpose (including, without limitation, the payment of the
principal of, or premium, if any, or interest on any Note) the Trustee shall not
have received, with respect to such monies, the notice provided for in this
Section 4.5, then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such monies and to
apply the same to the purpose for which they were received, and shall not be
affected by any notice to the contrary which may be received by it on or after
such prior date.

       Notwithstanding anything to the contrary hereinbefore set forth, nothing
shall prevent (a) any payment by the Company or the Trustee to the Noteholders
of amounts in connection with a redemption of Notes (including a redemption
pursuant to Section 3.5) if (i) notice of such redemption has been given
pursuant to Article III prior to the receipt by the Trustee of written notice as
aforesaid, and (ii) such notice of redemption is given not earlier than sixty
(60) days before the redemption date or (b) any payment by the Trustee to the
Noteholders of monies deposited with it pursuant to Section 13.1.

       The Trustee, subject to the provisions of Section 8.1, shall be entitled
to rely on the delivery to it of a written notice by a person representing
himself to be a holder of Senior Indebtedness (or a trustee on behalf of such
holder) to establish that such notice has been given by a holder of Senior
Indebtedness or a trustee on behalf of any such holder or holders.  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 IV, 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 IV, and if such evidence is not furnished the Trustee
may defer any payment to such person pending judicial determination as to the
right of such person to receive such payment.

       Section 4.6    TRUSTEE'S RELATION TO SENIOR INDEBTEDNESS.  The Trustee in
its individual capacity shall be entitled to all the rights set forth in this
Article IV in respect of any Senior Indebtedness at any time held by it, to the
same extent as any other holder of


                                      -33-
<PAGE>

Senior Indebtedness, and nothing in Section 8.13 or elsewhere in this Indenture
shall deprive the Trustee of any of its rights as such holder.

       With respect to the holders of Senior Indebtedness, the Trustee
undertakes to perform or to observe only such of its covenants and obligations
as are specifically set forth in this Article IV, 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, subject to the
provisions of Section 8.1, the Trustee shall not be liable to any holder of
Senior Indebtedness if it shall pay over or deliver to holders of Notes, the
Company or any other person money or assets to which any holder of Senior
Indebtedness shall be entitled by virtue of this Article IV or otherwise.

       Section 4.7    NO IMPAIRMENT OF SUBORDINATION.  No right of any present
or future holder of any Senior Indebtedness to enforce subordination as herein
provided shall at any time in any way be prejudiced or impaired by any act or
failure to act on the part of the Company or by any act or failure to act, in
good faith, by any such holder, or by any noncompliance by the Company with the
terms, provisions and covenants of this Indenture, regardless of any knowledge
thereof which any such holder may have or otherwise be charged with.

       Section 4.8    CERTAIN CONVERSIONS DEEMED PAYMENT.  For the purposes of
this Article IV only, (1) the issuance and delivery of junior securities upon
conversion of Notes in accordance with Article XV shall not be deemed to
constitute a payment or distribution on account of the principal of (or premium,
if any) or interest on Notes or on account of the purchase or other acquisition
of Notes, and (2) the payment, issuance or delivery of cash, property or
securities (other than junior securities) upon conversion of a Note shall be
deemed to constitute payment on account of the principal of such Note.  For the
purposes of this Section 4.8, the term "junior securities" means (a) shares of
any stock of any class of the Company, or (b) securities of the Company which
are subordinated in right of payment to all Senior Indebtedness which may be
outstanding at the time of issuance or delivery of such securities to
substantially the same extent as, or to a greater extent than, the Notes are so
subordinated as provided in this Article.  Nothing contained in this Article IV
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 Noteholders, the right, which is absolute and unconditional, of the
Holder of any Note to convert such Note in accordance with Article XV.

       Section 4.9    ARTICLE APPLICABLE TO PAYING AGENTS.  If at any time any
paying agent other than the Trustee shall have been appointed by the Company and
be then acting hereunder, the term "Trustee" as used in this Article shall
(unless the context otherwise requires) be construed as extending to and
including such paying agent within its meaning as fully for all intents and
purposes as if such paying agent were named in this Article in


                                      -34-
<PAGE>

addition to or in place of the Trustee; PROVIDED, HOWEVER, that the first
paragraph of Section 4.5 shall not apply to the Company or any Affiliate of the
Company if it or such Affiliate acts as paying agent.


                                    ARTICLE V

appear on the registry books of the Company; PROVIDED, that; with respect to any
holder of Notes with an aggregate principal amount equal to or in excess of

Notes shall be paid by wire transfer in immediately available funds in
accordance with the wire transfer instructions supplied by such holder to the
Trustee and paying agent (if different from the Trustee).

       Section 5.2    MAINTENANCE OF OFFICE OR AGENCY.  The Company will
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 will give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency not
designated or appointed by the Trustee.  If at any time the Company shall fail
to maintain any such required 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 or the office of the
Trustee in the Borough of Manhattan, The City of New York.

       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 will give prompt written
notice to any such designation or rescission and of any change in the location
of any such other office or agency.

              the Notes when the same shall be due and payable; and

the extent that it may lawfully do so) that it shall not at any time insist

       Company.  The Company will notify the Trustee within a reasonable time
       when the Notes are listed on any stock exchange and automated quotation
       system.

       Section 6.4    REPORTS BY COMPANY.  The Company shall file with the
Trustee (and the Commission if at any time after the Indenture becomes qualified
under the Trust Indenture Act), and transmit to holders of Notes, such
information, documents and other reports and such summaries thereof, as may be
required pursuant to the Trust Indenture Act at the times and in the manner
provided pursuant to such Act; PROVIDED that any such information, documents or
reports required to be filed with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act shall be filed with the Trustee within 15 days after the
same is so required to be filed with the Commission.

                                   ARTICLE VII


                     REMEDIES OF THE TRUSTEE AND NOTEHOLDERS
                             ON AN EVENT OF DEFAULT

       Section 7.1    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)  default in the payment of any installment of interest
       (including, without limitation, any interest payable as liquidated
       damages under the Registration Rights Agreement) upon any of the Notes as
       and when the same shall become due and payable, and continuance of such
       default for a period of thirty (30) days, whether or not such payment is
       permitted under Article IV hereof; or

              (b)  default in the payment of the principal of and premium, if
       any, on any of the Notes as and when the same shall become due and
       payable either at maturity or in connection with any redemption pursuant
       to Article III, by acceleration or otherwise, whether or not such payment
       is permitted under Article IV hereof; or

              (c)  failure on the part of the Company duly to observe or perform
       any other of the covenants or agreements on the part of the Company in
       the Notes or in this Indenture (other than a covenant or agreement a
       default in whose performance or whose breach is elsewhere in this Section
       7.1 specifically dealt with) continued for a period of sixty (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 percent in aggregate principal amount of the
       Notes at the time outstanding determined in accordance with Section 9.4;
       or

              (d) 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


                                      -40-
<PAGE>

              (e)  an involuntary case or other proceeding shall be commenced
       against 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
       ninety (90) consecutive days;

then, and in each and every such case (other than an Event of Default specified
in Section 7.1(d) or (e)), 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 percent in aggregate principal amount of the Notes then outstanding
hereunder determined in accordance with Section 9.4, by notice in writing to the
Company (and to the Trustee if given by Noteholders), may declare the principal
of all 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 specified in
Section 7.1(d) or (e) occurs, the principal of all the Notes and the interest
accrued thereon shall be immediately and automatically due and payable without
necessity of further action.  This provision, however, is subject to the
conditions that if, at any time after the principal of the Notes shall have been
so declared 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 which 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
8.6, and if any and all defaults under this Indenture, other than the nonpayment
of principal of and premium, if any, and accrued interest on Notes which shall
have become due by acceleration, shall have been cured or waived pursuant to
Section 7.7 -- 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 thereon.  The Company
shall notify a Responsible Officer of the Trustee, promptly upon becoming aware
thereof, of any Event of Default.

       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


                                      -41-
<PAGE>

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.

       Section 7.2    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 period of thirty
(30) 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 or under this Indenture declaration or otherwise -- then,
upon demand of the Trustee, the Company will 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 and premium, if any, or interest, or
both, as the case may be, with interest upon the overdue principal and 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


                                      -42-
<PAGE>

to the provisions of this Section 7.2, 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 Noteholders
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
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 8.6; and any receiver, assignee or trustee in
bankruptcy or reorganization, liquidator, custodian or similar official is
hereby authorized by each of the Noteholders 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 Noteholders, 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
which 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 Noteholder any plan of
reorganization or arrangement affecting the Notes or the rights of any
Noteholder, or to authorize the Trustee to vote in respect of the claim of any
Noteholder 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.

       Section 7.3      APPLICATION OF MONIES COLLECTED BY TRUSTEE.  Any monies
collected by the Trustee pursuant to this Article VII 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


                                      -43-
<PAGE>

the several Notes, and stamping thereon the payment, if only partially paid, and
upon surrender thereof, if fully paid:

              First:  To the payment of all amounts due the Trustee under
       Section 8.6;

              Second:  Subject to the provisions of Article IV, 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;

              Third:  Subject to the provisions of Article IV, 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 owing
       and unpaid upon the Notes for principal and 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
       and 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; and

              Fourth:  Subject to the provisions of Article IV, to the payment
       of the remainder, if any, to the Company or any other person lawfully
       entitled thereto.

       Section 7.4    PROCEEDINGS BY NOTEHOLDER.  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 percent 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 sixty (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


                                      -44-
<PAGE>

Section 7.7; 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, or 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 of all holders of Notes
(except as otherwise provided herein).  For the protection and enforcement of
this Section 7.4, each and every Noteholder 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 and 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.

       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.

       Section 7.5    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.

       Section 7.6    REMEDIES CUMULATIVE AND CONTINUING.  Except as provided in
Section 2.6, all powers and remedies given by this Article VII to the Trustee or
to the Noteholders shall, to the extent permitted by law, be deemed cumulative
and not exclusive of any thereof 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
7.4, every power and remedy given by this Article VII or by law to the Trustee
or to the Noteholders may be


                                      -45-
<PAGE>


exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Noteholders.

       Section 7.7    DIRECTION OF PROCEEDINGS AND WAIVER OF DEFAULTS BY
MAJORITY OF NOTEHOLDERS.  The holders of a majority in aggregate principal
amount of the Notes at the time outstanding determined in accordance with
Section 9.4 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, HOWEVER, 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 which
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 9.4 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,
(iii) a default in the payment of redemption price pursuant to Article III or
(iv) a default in respect of a covenant or provisions hereof which under Article
XI cannot be modified or amended without the consent of the holders of all Notes
then outstanding. Upon any such waiver 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.  Whenever any default or Event
of Default hereunder shall have been waived as permitted by this Section 7.7,
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; but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent thereon.

       Section 7.8    NOTICE OF DEFAULTS.  The Trustee shall, within ninety (90)
days after it has knowledge of the occurrence of a default, mail to all
Noteholders, 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; and
PROVIDED that, except in the case of default in the payment of the principal of,
or 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 Noteholders.

       Section 7.9    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,


                                      -46-
<PAGE>

including reasonable attorneys' fees, 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 7.9 (to the
extent permitted by law) shall not apply to any suit instituted by the Trustee,
to any suit instituted by any Noteholder, or group of Noteholders, holding in
the aggregate more than ten percent in principal amount of the Notes at the time
outstanding determined in accordance with Section 9.4, or to any suit instituted
by any Noteholder for the enforcement of the payment of the principal of or
premium, if any, or interest on any Note on 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 XV.


                                  ARTICLE VIII

                             CONCERNING THE TRUSTEE

       Section 8.1    DUTIES AND RESPONSIBILITIES OF TRUSTEE.  The Trustee,
prior to the occurrence of an Event of Default and after the curing of all
Events of Default which may have occurred, undertakes to perform such duties and
only such duties as are specifically set forth in this Indenture.  In case an
Event of Default has occurred (which has not been cured or waived) the Trustee
shall exercise such of the rights and powers vested in it by this Indenture, and
use the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his own affairs.

       No provision of this Indenture shall be construed to relieve the Trustee
from liability for its own negligent action, its own negligent failure to act or
its own willful misconduct, except that

              (a)  prior to the occurrence of an Event of Default and after the
       curing or waiving of all Events of Default which may have occurred:

                    (1)  the duties and obligations of the Trustee shall be
              determined solely by the express provisions of this Indenture and
              the Trust Indenture Act, and the Trustee shall not be liable
              except for the performance of such duties and obligations as are
              specifically set forth in this Indenture and no implied covenants
              or obligations shall be read into this Indenture and the
              Trust Indenture Act against the Trustee; and

                    (2)  in the absence of bad faith and willful misconduct on
              the part of the Trustee, the Trustee may conclusively rely, as to
              the truth of the statements and the correctness of the opinions
              expressed therein, upon any certificates or opinions furnished to
              the Trustee and conforming to the requirements of this Indenture;
              but, in the case of any such certificates or


                                      -47-
<PAGE>

              opinions which by any provisions 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;

              (b)  the Trustee shall not be liable for any error of judgment
       made in good faith by a Responsible Officer or Officers of the Trustee,
       unless the Trustee was negligent in ascertaining the pertinent facts;

              (c)  the Trustee shall not be liable with respect to any action
       taken or omitted to be taken by it in good faith in accordance with the
       direction of the holders of not less than a majority in principal amount
       of the Notes at the time outstanding determined as provided in Section
       9.4 relating to the time, method and place of conducting any proceeding
       for any remedy available to the Trustee, or exercising any trust or power
       conferred upon the Trustee, under this Indenture; and

              (d)  whether or not therein provided, every provision of this
       Indenture relating to the conduct or affecting the liability of, or
       affording protection to, the Trustee shall be subject to the provisions
       of this Section.

       None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there is reasonable ground for believing that the
repayment of such funds or adequate indemnity against such risk or liability is
not reasonably assured to it.

       Section 8.2    RELIANCE ON DOCUMENTS, OPINIONS. ETC.  Except as otherwise
provided in Section 8.1:

              (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, note, 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); and any resolution of the Board of Directors
       may be evidenced to the Trustee by a copy thereof certified by the
       Secretary or an Assistant Secretary of the Company;

              (c)  the Trustee may consult with counsel and any advice or
       Opinion of Counsel shall be full and complete authorization and
       protection in respect of any


                                      -48-
<PAGE>

       action taken or omitted by it hereunder in good faith and in accordance
       with such advice or Opinion of Counsel;

              (d)  the Trustee shall be under no obligation to exercise any of
       the rights or powers vested in it by this Indenture at the request, order
       or direction of any of the Noteholders pursuant to the provisions of this
       Indenture, unless such Noteholders shall have offered to the Trustee
       reasonable security or indemnity against the costs, expenses and
       liabilities which may be incurred therein or thereby;

              (e)  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 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; PROVIDED, HOWEVER, that if the
       payment within a reasonable time to the Trustee of the costs, expenses or
       liabilities likely to be incurred by it in the making of such
       investigation is, in the opinion of the Trustee, not reasonably assured
       to the Trustee by the security afforded to it by the terms of this
       Indenture, the Trustee may require reasonable indemnity against such
       expenses or liability as a condition to so proceeding; the reasonable
       expenses of every such examination shall be paid by the Company or, if
       paid by the Trustee or any predecessor Trustee, shall be repaid by the
       Company upon demand; and

              (f)  the Trustee may execute any of the trusts or powers hereunder
       or perform any duties hereunder either directly or by or through agents
       or attorneys and the Trustee shall not be responsible for any misconduct
       or negligence on the part of any agent or attorney appointed by it with
       due care hereunder.

       Section 8.3    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.

       Section 8.4    TRUSTEE, PAYING AGENTS, CONVERSION AGENTS OR REGISTRAR MAY
OWN NOTES.  The Trustee, any paying agent, any conversion agent or 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.

       Section 8.5    MONIES TO BE HELD IN TRUST.  Subject to the provisions of
Section 13.4, 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 from time to time by the Company and the Trustee.

       Section 8.6    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, reasonable compensation 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
will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances reasonably 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 its negligence, willful misconduct, recklessness or
bad faith.  The Company also covenants to indemnify the Trustee in any capacity
under this Indenture and its agents and any authenticating agent for, and to
hold them harmless against, any loss, liability or expense incurred without
negligence, willful misconduct, recklessness, 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 8.6 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.  The obligation of the Company under this
Section shall survive the satisfaction and discharge of this Indenture.

       When the Trustee and its agents and any authenticating agent incur
expenses or render services after an Event of Default specified in Section
7.1(d) or (e) occurs, the expenses and the compensation for the services are
intended to constitute expenses of administration under any bankruptcy,
insolvency or similar laws.

       Section 8.7    OFFICERS' CERTIFICATE AS EVIDENCE.  Except as otherwise
provided in Section 8.1, 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, willful misconduct, recklessness,
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.

       Section 8.8    CONFLICTING INTERESTS OF TRUSTEE.  If the Trustee has or
shall acquire a conflicting interest within the meaning of the Trust Indenture
Act, 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.

       Section 8.9    ELIGIBILITY OF TRUSTEE.  There shall at all times be a
Trustee hereunder which shall be a Person that is eligible pursuant to the Trust
Indenture Act to act as such and 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 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.

       Section 8.10   RESIGNATION OR REMOVAL OF TRUSTEE.

              (a)  The Trustee may at any time resign by giving written notice
       of such resignation to the Company and to the holders of Notes.  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.
       If no successor trustee shall have been so appointed and have accepted
       appointment sixty (60) days after the mailing of such notice of
       resignation to the Noteholders, the resigning Trustee may petition any
       court of competent jurisdiction for the appointment of a successor
       trustee, or any Noteholder who has been a bona fide holder of a Note or
       Notes for at least six months may, subject to the provisions of Section
       7.9, 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.

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

                    (1)  the Trustee shall fail to comply with Section 8.8 after
              written request therefor by the Company or by any Noteholder 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 8.9 and shall fail to resign after
              written request therefor by the Company or by any such Noteholder;
              or


                                      -51-
<PAGE>

                    (3)  the Trustee shall become incapable of acting, or shall
              be adjudged a 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, subject to the provisions of Section 7.9, any Noteholder 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.

              (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 (10) days after notice to the Company of such
       nomination the Company objects thereto, in which case the Trustee so
       removed or any Noteholder, upon the terms and conditions and otherwise as
       in Section 8.10(a) provided, may petition any court of competent
       jurisdiction for an appointment of 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
       8.10 shall become effective upon acceptance of appointment by the
       successor trustee as provided in Section 8.11.

       Section 8.11   ACCEPTANCE BY SUCCESSOR TRUSTEE.  Any successor trustee
appointed as provided in Section 8.10 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, nevertheless, 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
8.6, 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,


                                       -52
<PAGE>

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 8.6.

       No successor trustee shall accept appointment as provided in this Section
8.11 unless at the time of such acceptance such successor trustee shall be
qualified under the provisions of Section 8.8 and be eligible under the
provisions of Section 8.9.

       Upon acceptance of appointment by a successor trustee as provided in this
Section 8.11, each of the Company and the former trustee 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 (10) 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.

       Section 8.12   SUCCESSION 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 trust business of the Trustee, shall be the successor to the Trustee
hereunder without the execution or filing of any paper or any further act on the
part of any of the parties hereto, provided that in the case of any corporation
succeeding to all or substantially all of the trust business of the Trustee such
corporation shall be qualified under the provisions of Section 8.8 and eligible
under the provisions of Section 8.9.

       In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture, any of the Notes shall have been authenticated
but not delivered, any such successor to the Trustee may adopt the certificate
of authentication of any predecessor trustee or authenticating agent appointed
by such predecessor trustee, and deliver such Notes so authenticated; and in
case at that time any of the Notes shall not have been authenticated, any
successor to the Trustee or an authenticating agent appointed by such successor
trustee may authenticate such Notes either in the name of any predecessor
trustee hereunder or in the name of the successor trustee; and in all such cases
such certificates shall have the full force which it is anywhere in the Notes or
in this Indenture provided that the certificate of the Trustee shall have;
PROVIDED, HOWEVER, that the right to adopt the certificate of authentication of
any predecessor Trustee or authenticate Notes in the name of any predecessor
Trustee shall apply only to its successor or successors by merger, conversion or
consolidation.

       Section 8.13   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), the Trustee shall be subject to the provisions of the Trust
Indenture Act regarding the collection of the claims against the Company (or any
such other obligor).

                           CONCERNING THE NOTEHOLDERS

       Section 9.1    ACTION BY NOTEHOLDERS.  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 Noteholders
in person or by agent or proxy appointed in writing, or (b) by the record of the
holders of Notes voting in favor thereof at any meeting of Noteholders duly
called and held in accordance with the provisions of Article X, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of Noteholders.  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 record date for determining holders
entitled to take such action.  The record date shall be not more than fifteen
(15) days prior to the date of commencement of solicitation of such action.

       Section 9.2    PROOF OF EXECUTION BY NOTEHOLDERS.  Subject to the
provisions of Sections 8.1, 8.2 and 10.5, proof of the execution of any
instrument by a Noteholder or his 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 registry of such Notes or by a
certificate of the Note registrar.

      The record of any Noteholders' meeting shall be proved in the manner
provided in Section 10.6.

       Section 9.3    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 Note register to be,
and may treat him 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 his order, 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.

       Section 9.4    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
which 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; 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 which a Responsible Officer knows are so owned shall be so
disregarded.  Notes so owned which have been pledged in good faith may be
regarded as outstanding for the purposes of this Section 9.4 if the pledgee
shall establish to the satisfaction of the Trustee the pledgee'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 8.1, 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.

       Section 9.5    REVOCATION OF CONSENTS: FUTURE HOLDERS BOUND.  At any time
prior to (but not after) the evidencing to the Trustee, as provided in Section
9.1, 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 which 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 9.2, 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.

Notes held or represented by him; PROVIDED, HOWEVER, that no vote shall be cast

affidavits by one or more persons having knowledge of the facts setting forth a

     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, HOWEVER, 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

     purpose;

          (f)  to cure any ambiguity or to correct or supplement any provision
     contained herein or in any supplemental indenture which 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 which shall not
     materially adversely affect the interests of the holders of the Notes;

     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 as shall be necessary to effect the qualifications of this
     Indenture under the Trust Indenture Act, or under any similar federal
     statute hereafter enacted.

of any such supplemental indenture, to make any further appropriate agreements
and stipulations which 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

     Section 11.3  EFFECT OF SUPPLEMENTAL INDENTURE.  Any supplemental indenture
executed pursuant to the provisions of this Article XI shall comply with the
Trust Indenture Act, as then in effect; PROVIDED that this Section 11.3 shall

the Trust Indenture Act prior to the time such qualification is in fact required
under the terms of the Trust Indenture Act or the Indenture has been qualified

acknowledgment by any party to such supplemental indenture that any such
qualification is required prior to the time such qualification is in
fact required under the terms of the Trust Indenture Act or the Indenture has
been qualified under the Trust Indenture Act.  Upon the execution of any

of the Trustee and the Board of Directors, to any modification of this Indenture

Notes then outstanding.

     Section 11.5   EVIDENCE OF COMPLIANCE OF SUPPLEMENTAL INDENTURE TO BE

                CONSOLIDATION, MERGER, SALE, CONVEYANCE AND LEASE

     Section 12.1   COMPANY MAY CONSOLIDATE ETC. ON CERTAIN TERMS.  Subject to
the provisions of Section 12.2, nothing contained in this Indenture or in any
of the Notes shall prevent any consolidation or merger of the Company with
or into any other corporation or

                                      -61-

<PAGE>

corporations (whether or not affiliated with the Company), or successive
consolidations or mergers in which the Company or its successor or successors
shall be a party or parties, or shall prevent any sale, conveyance or lease (or
successive sales, conveyances or leases) of all or substantially all of the
property of the Company, to any other corporation (whether or not affiliated
with the Company), authorized to acquire and operate the same and which shall be
organized under the laws of the United States of America, any state thereof or
the District of Columbia; PROVIDED, that upon any such consolidation, merger,
sale, conveyance or lease, the due and punctual payment of the principal of and
premium, if any, and interest on all of the Notes, according to their tenor, and
the due and punctual performance and observance of all of the covenants and
conditions of this Indenture to be performed by the Company, shall be expressly
assumed, by supplemental indenture satisfactory in form to the Trustee, executed
and delivered to the Trustee by the corporation (if other than the Company)
formed by such consolidation, or into which the Company shall have been merged,
or by the corporation which shall have acquired or leased such property, and
such supplemental indenture shall provide for the applicable conversion rights
set forth in Section 15.6.

     Section 12.2   SUCCESSOR CORPORATION TO BE SUBSTITUTED.  In case of any
such consolidation, merger, sale, conveyance or lease and upon the assumption by
the successor corporation, 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 and 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
corporation shall succeed to and be substituted for the Company, with the same
effect as if it had been named herein as the party of the first part.  Such
successor corporation thereupon may cause to be signed, and may issue either in
its own name or in the name of National Semiconductor Corporation any or all of
the Notes issuable hereunder which theretofore shall not have been signed by the
Company and delivered to the Trustee; and, upon the order of such successor
corporation instead of the Company and subject to all the terms, conditions and
limitations in this Indenture prescribed, the Trustee shall authenticate and
shall deliver, or cause to be authenticated and delivered, any Notes which
previously shall have been signed and delivered by theofficers of the Company to
the Trustee for authentication, and any Notes which such successor corporation
thereafter shall cause to be signed and delivered to the Trustee for that
purpose.  All the Notes so issued shall in all respects have the same legal rank
and benefit under this Indenture as the Notes theretofore or thereafter issued
in accordance with the terms of this Indenture as though all of such Notes had
been issued at the date ofthe execution hereof.  In the event of any such
consolidation, merger, sale, conveyance or lease, the person named as the
"Company" in the first paragraph of this Indenture or any successor which shall
thereafter have become such in the manner prescribed in this Article XII may be
dissolved, wound up and liquidated at any time thereafter and suchperson shall
be released from its liabilities as obligor and maker of the Notes and from its
obligations under this Indenture.

                                      -62-

      In case of any such consolidation, merger, sale, conveyance or lease, such
changes in phraseology and form (but not in substance) may be made in the Notes
thereafter to be issued as may be appropriate.

     Section 12.3   OPINION OF COUNSEL TO BE GIVEN TRUSTEE.  The Trustee,
subject to Sections 8.1 and 8.2, shall receive an Officers' Certificate and an
Opinion of Counsel as conclusive evidence that any such consolidation, merger,
sale, conveyance or lease and any such assumption complies with the provisions
of this Article XII.

                     SATISFACTION AND DISCHARGE OF INDENTURE

     Section 13.1   DISCHARGE OF INDENTURE.  When (a) the Company shall deliver
to the Trustee for cancellation all Notes theretofore authenticated (other than
any Notes which have been destroyed, lost or stolen and in lieu of or in
substitution for which other Notes shall have been authenticated and delivered)
and not theretofore canceled, or (b) all the Notes not theretofore canceled or
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 within one year under arrangements satisfactory to the Trustee
for the giving of notice of redemption, and the Company shall deposit with the
Trustee, in trust, funds sufficient to pay at maturity or upon redemption of all
of the Notes (other than any Notes which shall have been mutilated, destroyed,
lost or stolen and in lieu of or in substitution for which other Notes shall
have been authenticated and delivered) not theretofore canceled or delivered to
the Trustee for cancellation, including principal and premium, if any, and
interest due or to become due to such date of maturity or redemption date, as
the case may be, and if in either case the Company shall also pay or cause to be
paid all other sums payable hereunder by the Company, then this Indenture shall
cease to be of further effect (except as to (i) remaining rights of registration
of transfer, substitution and exchange and conversion of Notes, (ii) rights
hereunder of Noteholders to receive payments of principal of and premium, if
any, and interest on, the Notes and the other rights, duties and obligations of
Noteholders, as beneficiaries hereof with respect to the amounts, if any, so
deposited with the Trustee and (iii) the rights, obligations and immunities of
the Trustee hereunder), and the Trustee, on demand of the Company accompanied by
an Officers' Certificate and an Opinion of Counsel as required by Section 16.5
and at the cost and expense of the Company, shall execute proper instruments
acknowledging satisfaction of and discharging this Indenture; the Company,
however, hereby agreeing to reimburse the Trustee for any costs or expenses
thereafter reasonably and properly incurred by the Trustee and to compensate the
Trustee for any services thereafter reasonably and properly rendered by the
Trustee in connection with this Indenture or the Notes.

to Article IV and Section 13.4, all monies deposited with the Trustee pursuant
to Section 13.1 shall be held in trust and applied by it to the payment, either
directly or through any paying agent (including the Company if acting as its own
paying agent), to the holders of the particular Notes for the payment or
redemption of which such monies havebeen deposited with the Trustee, of all sums
due and to become due thereon for principal and interest and premium, if any.

     Section 13.3   PAYING AGENT TO REPAY MONIES HELD.  Upon the satisfaction
and discharge of this Indenture, all monies then held by any paying agent of the

it or paid to the Trustee, and thereupon such paying agent shall be released
from all further liability with respect to such monies.

     Section 13.4   RETURN OF UNCLAIMED MONIES.  Subject to the requirements of
applicable law, any monies deposited with or paid to the Trustee for payment of
the principal of, premium, if any, or interest on Notes and not applied but

upon which the principal of, premium, if any, or interest on such Notes, as
the case may be, shall have become due and payable, shall be repaid to
the Company by the Trustee on demand and all liability of the Trustee
shall thereupon cease with respect to such monies; and the holder of any of
the Notes shall thereafter look only to the Company for any payment which
such holder may be entitled to collect unless an applicable abandoned
property law designates another Person.

     Section 13.5   REINSTATEMENT.  If the Trustee or the paying agent is unable
to apply any money in accordance with Section 13.2 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 13.1 until such time as the Trustee
or the paying agent is permitted to apply all such money in accordance
with Section 13.2; PROVIDED, HOWEVER,  that if the Company makes any payment of
interest on or principal of any Note 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 money held by the Trustee or paying
agent.

                                   ARTICLE XIV

                    IMMUNITY OF INCORPORATORS, STOCKHOLDERS,
                             OFFICERS AND DIRECTORS

     Section 14.1   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, employee, agent, officer, or director or subsidiary,
as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, 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 issue of the Notes.


                                   ARTICLE XV

                               CONVERSION OF NOTES

     Section 15.1   RIGHT TO CONVERT.  Subject to and upon compliance with the
provisions of this Indenture, the holder of any Note shall have the right, at
his option, at any time after sixty (60) days following the latest date of
original issuance of the Notes and prior to the close of business on October 1,
2002 (except that, with respect to any Note or portion of a Note which shall be
called for redemption, such right shall terminate, except as provided in Section
15.2 or Section 3.4, at the close of business on the Business Day next preceding
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 which
is $1,000 or an integral multiple thereof, into that number of fully paid and
non-assessable shares of Common Stock (as such shares shall then be constituted)
obtained by dividing the principal amount of the Note or portion thereof
surrendered for conversion by the Conversion Price in effect at such time, by
surrender of the Note so to be converted in whole or in part in the manner
provided, together with any required funds, in Section 15.2. A holder of Notes
is not entitled to any rights of a holder of Common Stock until such holder has
converted his Notes to Common Stock, and only to the extent such Notes are
deemed to have been converted to Common Stock under this Article XV.

     Section 15.2   EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF COMMON STOCK
ON CONVERSION; NO ADJUSTMENT FOR INTEREST OR DIVIDENDS.  In order to exercise
the conversion

                                      -65-

<PAGE>

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
5.2, accompanied by the funds, if any, required by the penultimate paragraph of
this Section 15.2, and shall give written notice of conversion in the form
provided on the Notes (or such other notice which 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 or addresses) in which the certificate or certificates
for shares of Common Stock which shall be issuable on such conversion shall be
issued, and shall be accompanied by transfer taxes, if required pursuant to
Section 15.7.  Each such Note surrendered for conversion shall, unless the
shares issuable on conversion are to be issued in the same name as the
registration of such Note, 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.

      In order to exercise the conversion privilege with respect to any interest
in a Note in global form, the beneficial holder must complete the appropriate
instruction form for conversion pursuant to the Depository's book-entry
conversion program, deliver by book-entry delivery an interest in such Note in
global form, furnish appropriate endorsements and transfer documents if required
by the Company or the Trustee or conversion agent, and pay the funds, if any,
required by this Section 15.2 and any transfer taxes if required pursuant to
Section 15.7.

     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 Noteholder (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 5.2, a certificate or certificates for the number of full
shares of Common Stock issuable upon the conversion of such Note or portion
thereof in accordance with the provisions of this Article 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 15.3.  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 deliver 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 15.2 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

                                      -66-

<PAGE>

the shares represented thereby; PROVIDED, HOWEVER, 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 be 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 to
the close of business on the Business Day next preceding the following interest
payment date shall (unless such Note or portion thereof being converted shall
have been called for redemption during the period from the close of business on
such record date to the close of business on the Business Day next preceding the
following interest payment date) be accompanied by payment, in New York Clearing
House funds or other 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, HOWEVER, 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.  Except as provided above in this Section 15.2, 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.

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

     Section 15.3   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 full shares which shall
be issuable upon conversion shall be computed on the basis of the aggregate
principal amount of the Notes (or specified portions thereof to the extent
permitted hereby) so surrendered.  If any fractional share of stock would be
issuable upon the conversion of any Note or Notes, the Company shall make an
adjustment and payment therefor in cash at the current market value thereof to
the holder of Notes.  The current market value of a share of Common Stock shall
be the Closing Price on the first Business Day immediately preceding the day on
which the Notes (or specified portions thereof) are deemed to have been
converted and such Closing Price shall be determined as provided in Section
15.5(g).

     Section 15.4   CONVERSION PRICE.  The conversion price shall be as
specified in the form of Note (herein called the "Conversion Price") attached as
Exhibit A hereto, subject to adjustment as provided in this Article XV.

                                      -67-

<PAGE>

     Section 15.5   ADJUSTMENT OF CONVERSION PRICE.  The Conversion Price shall
be adjusted from time to time by the Company as follows:

          (a)  In case the Company shall hereafter pay a dividend or make a
     distribution to all holders of the outstanding Common Stock in shares of
     Common Stock, the Conversion Price in effect at the opening of business on
     the date following the date fixed for the determination of stockholders
     entitled to receive such dividend or other distribution shall be reduced by
     multiplying such Conversion Price 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 reduction to become
     effective immediately after the opening of business on the day following
     the date fixed for such determination. The Company will not pay any
     dividend or make any distribution on shares of Common Stock held in the
     treasury of the Company. If any dividend or distribution of the type
     described in this Section 15.5(a) is declared but not so paid or made, the
     Conversion Price shall again be adjusted to the Conversion Price which
     would then be in effect if such dividend or distribution had not been
     declared.

          (b)  In case the Company shall issue rights 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 or warrants) to subscribe for
     or purchase shares of Common Stock at a price per share less than the
     Current Market Price (as defined below) on the date fixed for determination
     of stockholders entitled to receive such rights or warrants, 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 the date
     fixed for determination of stockholders entitled to receive such rights or
     warrants 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
     determination of stockholders entitled to receive such rights and warrants
     plus the number of shares which the aggregate offering price of the total
     number of shares so offered would purchase at such Current Market Price,
     and of which the denominator shall be the number of shares of Common Stock
     outstanding on the date fixed for determination of stockholders entitled to
     receive such rights and warrants plus the total number of additional shares
     of Common Stock offered for subscription or purchase. Such adjustment shall
     be successively made whenever any such rights and warrants are issued, and
     shall become effective immediately after the opening of business on the day
     following the date fixed for determination of stockholders entitled to
     receive such rights or warrants. To the extent that shares of Common Stock
     are not delivered after the expiration of such rights or warrants, the
     Conversion Price shall be readjusted to the Conversion Price which would
     then

                                      -68-

<PAGE>

     be in effect had the adjustments made upon the issuance of such rights 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 or warrants
     are not so issued, the Conversion Price shall again be adjusted to be the
     Conversion Price which would then be in effect if such date fixed for the
     determination of stockholders entitled to receive such rights or warrants
     had not been fixed. In determining whether any rights 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 by the Company for such rights or warrants, the
     value of such consideration, if other than cash, to be determined by the
     Board of Directors.

          (c)  In case outstanding shares of Common Stock shall be subdivided
     into a greater number of shares of Common Stock, the Conversion Price in
     effect at the opening of business on the day following the day upon which
     such subdivision becomes effective shall be proportionately reduced, and
     conversely, in case outstanding shares of Common Stock shall be combined
     into a smaller number of shares of Common Stock, the Conversion Price in
     effect at the opening of business on the day following the day upon which
     such combination becomes effective shall be proportionately increased, 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.


          (d)  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
     15.5(a) applies) or evidences of its indebtedness or assets (including
     securities, but excluding any rights or warrants referred to in Section
     15.5(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) paid exclusively in cash or (z) referred to
     in Section 15.5(a) (any of the foregoing hereinafter in this Section
     15.5(d) called the "Securities")), then, in each such case (unless the
     Company elects to reserve such Securities for distribution to the
     Noteholders upon the conversion of the Notes so that any such holder
     converting Notes will receive upon such conversion, in addition to the
     shares of Common Stock to which such holder is entitled, the amount and
     kind of such Securities which such holder would have received if such
     holder had converted its Notes into Common Stock immediately prior to the
     Record Date (as defined in Section 15.5(h) for such distribution of the
     Securities)), the Conversion Price shall be reduced so that the same shall
     be equal to the price determined by multiplying the Conversion Price in
     effect on the Record Date with respect to such distribution by a fraction
     of which the numerator shall be the Current Market Price per share of the
     Common Stock on such Record Date less the fair market value (as determined
     by the Board of

                                      -69-

<PAGE>

     Directors, whose determination shall be conclusive, and described in a
     resolution of the Board of Directors) on the Record Date of the portion of
     the Securities so distributed applicable to one share of Common Stock and
     the denominator shall be the Current Market Price per share of the Common
     Stock, such reduction to become effective immediately prior to the opening
     of business on the day following such Record Date; PROVIDED, HOWEVER, 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 of the Common Stock on
     the Record Date, in lieu of the foregoing adjustment, adequate provision
     shall be made so that each Noteholder shall have the right to receive upon
     conversion the amount of Securities 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 which would then be in effect
     if such dividend or distribution had not been declared. If the Board of
     Directors determines the fair market value of any distribution for purposes
     of this Section 15.5(d) by reference to the actual or when issued trading
     market for any securities, it must in doing so consider the prices in such
     market over the same period used in computing the Current Market Price of
     the Common Stock.

          The Company will promptly amend the Rights Agreement (in no event
     later than October 31, 1995) (the "Rights Agreement Amendment") to provide
     that, upon conversion of any Note or portion thereof, the Noteholder will
     receive, in addition to the Common Stock issuable upon such conversion, the
     Rights which would have attached to such shares of Common Stock if the
     Rights had not become separated from the Common Stock pursuant to the
     provisions of the Rights Agreement. In the event that the Company
     implements any new stockholders' rights plan (a "New Rights Agreement"),
     such New Rights Agreement shall provide that upon conversion of the Notes
     the holders will receive, in addition to the Common Stock issuable upon
     such conversion, the rights (whether or not such rights have separated from
     Common Stock at the time of the conversion) issuable pursuant to the New
     Rights Agreement.

          Rights 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 or warrants, until the occurrence of a
     specified event or events ("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
     be deemed not to have been distributed for purposes of this Section 15.5
     (and no adjustment to the Conversion Price under this Section 15.5 will be
     required) until the occurrence of the earliest Trigger Event, whereupon
     such rights and warrants shall be deemed to have been distributed and an
     appropriate

                                      -70-

<PAGE>

     adjustment (if any is required) to the Conversion Price shall be made under
     this Section 15.5(d). If any such right or warrant, including any such
     existing rights or warrants distributed prior to the date of this
     Indenture, are subject to events, upon the occurrence of which such rights
     or warrants become exercisable to purchase different securities, evidences
     of indebtedness or other assets, then the date of the occurrence of any and
     each such event shall be deemed to be the date of distribution and record
     date with respect to new rights or warrants with such rights (and a
     termination or expiration of the existing rights or warrants without
     exercise by any of the holders thereof). In addition, in the event of any
     distribution (or deemed distribution) of rights or warrants, or any Trigger
     Event or other event (of the type described in the preceding sentence) with
     respect thereto that was counted for purposes of calculating a distribution
     amount for which an adjustment to the Conversion Price under this Section
     15.5 was made, (1) in the case of any such rights or warrants which 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 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 Price
     shall be readjusted as if such rights and warrants had not been issued.

          For purposes of this Section 15.5(d) and Sections 15.5(a) and (b), any
     dividend or distribution to which this Section 15.5(d) is applicable that
     also includes shares of Common Stock, or rights 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 or warrants (and any Conversion Price reduction required by this
     Section 15.5(d) 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 or warrants (and any further Conversion
     Price reduction required by Sections 15.5(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 date fixed for
     the determination of stockholders entitled to receive such dividend or
     other distribution" and "the date fixed for such determination" within the
     meaning of Sections 15.5(a) and (b) and (B) any shares of Common Stock
     included in such dividend or distribution shall not be deemed "outstanding
     at the close of business on the date fixed for such determination" within
     the meaning of Section 15.5(a).

                                      -71-

<PAGE>

          (e)  In case the Company shall, by dividend or otherwise, distribute
     to all holders of its Common Stock cash (excluding (x) any quarterly cash
     dividend on the Common Stock to the extent the aggregate cash dividend per
     share of Common Stock in any fiscal quarter does not exceed the greater of
     (A) the amount per share of Common Stock of the next preceding quarterly
     cash dividend on the Common Stock to the extent that such preceding
     quarterly dividend did not require any adjustment of the Conversion Price
     pursuant to this Section 15.5(e) (as adjusted to reflect subdivisions or
     combinations of the Common Stock), and (B) 3.75% of the arithmetic average
     of the Closing Price (determined as set forth in Section 15.5(h)) during
     the ten Trading Days (as defined in Section 15.5(h)) immediately prior to
     the date of declaration of such dividend, and (y) any dividend or
     distribution in connection with the liquidation, dissolution or winding up
     of the Company, whether voluntary or involuntary), then, in such case, 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 of which the
     numerator shall be the Current Market Price of the Common Stock on the
     Record Date less the amount of cash so distributed (and not excluded as
     provided above) applicable to one share of Common Stock and the denominator
     shall be such Current Market Price of the Common Stock, such reduction to
     be effective immediately prior to the opening of business on the day
     following the Record Date; PROVIDED, HOWEVER, 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 Noteholder 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 which would then be in effect
     if such dividend or distribution had not been declared. If any adjustment
     is required to be made as set forth in this Section 15.5(e) as a result of
     a distribution that is a quarterly dividend, such adjustment shall be based
     upon the amount by which such distribution exceeds the amount of the
     quarterly cash dividend permitted to be excluded pursuant hereto. If an
     adjustment is required to be made as set forth in this Section 15.5(e)
     above as a result of a distribution that is not a quarterly dividend, such
     adjustment shall be based upon the full amount of the distribution.

          (f)  In case a tender or exchange offer made by the Company or any
     subsidiary of the Company for all or any portion of the Common Stock shall
     expire and such tender or exchange offer (as amended upon the expiration
     thereof) shall require the payment to stockholders of consideration per
     share of Common Stock having a fair market value (as determined by the
     Board of Directors, whose determination shall be conclusive and described
     in a resolution of the Board if

                                      -72-

<PAGE>

     Directors) that as of the last time (the "Expiration Time") tenders or
     exchanges may be made pursuant to such tender or exchange offer (as it may
     be amended) that exceeds the Current Market Price of the Common Stock on
     the Trading Day next succeeding the Expiration Time, 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
     Expiration Time by a fraction of which the numerator shall be the number of
     shares of Common Stock outstanding (including any tendered or exchanged
     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 shareholders based
     on the acceptance (up to any maximum specified in the terms of the tender
     or exchange offer) of all shares validly tendered or exchanged 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 or
     exchange 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 which
     would then be in effect if such tender or exchange offer had not been made.

          (g)  In case of a tender or exchange offer made by a person other than
     the Company or any Subsidiary for an amount which increases the offeror's
     ownership of Common Stock to more than 25% of the Common Stock outstanding
     and shall involve the payment by such person of consideration per share of
     Common Stock having a fair market value (as determined by the Board of
     Directors, whose determination shall be conclusive, and described in a
     resolution of the Board of Directors) at the last time (the "Expiration
     Time") tenders or exchanges may be made pursuant to such tender or exchange
     offer (as it shall have been amended) that exceeds the Current Market Price
     of the Common Stock on the Trading Day next succeeding the Expiration Time,
     and in which, as of the Expiration Time the Board of Directors is not
     recommending rejection of the offer, 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 Expiration Time by a
     fraction of which the numerator shall be the number of shares of Common
     Stock outstanding (including any tendered or exchanged 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


                                      -73-

<PAGE>

     payable to stockholders based on the acceptance (up to any maximum
     specified in the terms of the tender or exchange offer) of all shares
     validly tendered or exchanged 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 such person is obligated to purchase
     shares pursuant to any such tender or exchange offer, but such person 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 which would then be in effect if such
     tender or exchange offer had not been made. Notwithstanding the foregoing,
     the adjustment described in this Section 15.5(g) shall not be made if, as
     of the Expiration Time, the offering documents with respect to such offer
     disclose a plan or intention to cause the Company to engage in any
     transaction described in Article XII.

          (h)  For purposes of this Section 15.5, 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 or, to the extent
          permitted by applicable law, a duly authorized committee thereof,
          whose determination shall be conclusive.

               (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,
          HOWEVER, that (1) if the "ex" date (as hereinafter defined) for any
          event (other than the issuance or distribution or Fundamental Change
          requiring such

                                      -74-

<PAGE>

          computation) that requires an adjustment to the Conversion Price
          pursuant to Section 15.5(a), (b), (c), (d), (e), (f) or (g) 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 Fundamental Change requiring such
          computation) that requires an adjustment to the Conversion Price
          pursuant to Section 15.5(a), (b), (c), (d), (e), (f) or (g) 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 Fundamental Change 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 or, to the
          extent permitted by applicable law, a duly authorized committee
          thereof in a manner consistent with any determination of such value
          for purposes of Section 15.5(d), (f) or (g), whose determination shall
          be conclusive and described in a resolution of the Board of Directors
          or such duly authorized committee thereof, as the case may be) 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 15.5(f) or (g), 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, HOWEVER, 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 15.5(a), (b), (c), (d), (e), (f) or (g) 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 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

                                      -75-

<PAGE>

          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
          Time of such offer.

               (3)  "fair market value" shall mean the amount which 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 shareholders
          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 another 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 on 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.

          (i)  The Company may make such reductions in the Conversion Price, in
     addition to those required by Sections 15.5 (a), (b), (c), (d), (e), (f)
     and (g), 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 twenty (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. Whenever the Conversion
     Price is reduced pursuant to the preceding

                                      -76-

<PAGE>

     sentence, the Company shall mail to holders of record of the Notes a notice
     of the reduction at least fifteen (15) days prior to the date the reduced
     Conversion Price takes effect, and such notice shall state the reduced
     Conversion Price and the period during which it will be in effect.

          (j)  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, HOWEVER, that any adjustments which by reason of this
     Section 15.5(j) are not required to be made shall be carried forward and
     taken into account in any subsequent adjustment. All calculations under
     this Article XV shall be made by the Company and shall be made to the
     nearest cent or to the nearest one hundredth of a share, as the case may
     be. No adjustment need be made for rights to purchase Common Stock pursuant
     to a Company plan for reinvestment of dividends or interest. To the extent
     the Notes become convertible into cash, assets, property or securities
     (other than capital stock of the Company), no adjustment need be made
     thereafter as to the cash, assets, property or such securities. Interest
     will not accrue on the cash.

          (k)  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 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 of
     this Indenture, within 20 days after execution thereof. Failure to deliver
     such notice shall not affect the legality or validity of any such
     adjustment.

          (l)  In any case in which this Section 15.5 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 15.3.

          (m)  For purposes of this Section 15.5, 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

                                      -77-

<PAGE>

     dividend or make any distribution on shares of Common Stock held in the
     treasury of the Company.

     Section 15.6   EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE.
If any of the following events occur, namely (i) any reclassification or change
of the outstanding shares of Common Stock (other than a subdivision or
combination to which Section 15.5(c) applies), (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 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) providing that such Note 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
consolidation, merger, statutory exchange, sale or conveyance (provided that, if
the kind or amount of securities, cash or other property receivable upon such
consolidation, merger, statutory exchange, sale or conveyance is not the same
for each share of Common Stock in respect of which such rights of election shall
not have been exercised ("nonelecting share")), then for the purposes of this
Section 15.6 the kind and amount of securities, cash or other property
receivable upon such consolidation, merger, statutory exchange, 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 which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this
Article.

     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 of this Indenture, within twenty (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 shall similarly apply to successive
reclassifications, changes, consolidations, mergers, combinations, sales and
conveyances.

                                      -78-

<PAGE>

     If this Section 15.6 applies to any event or occurrence, Section 15.5 shall
not apply.

     Section 15.7   TAXES ON SHARES ISSUED.  The issue of stock certificates on
conversions of Notes shall be made without charge to the converting Noteholder
for any tax in respect of the issue thereof.  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 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
issue 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.

     Section 15.8   RESERVATION OF SHARES; SHARES TO BE FULLY PAID; COMPLIANCE
WITH GOVERNMENTAL REQUIREMENTS; 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 of Common Stock to provide for the
conversion of the Notes from time to time as such Notes are presented for
conversion.

     Before taking any action which 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 will take all corporate
action which 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 which may be issued
upon conversion of Notes will upon issue be fully paid and non-assessable by the
Company and free from all taxes, liens and charges with respect to the issue
thereof.

     The Company covenants that if any shares of Common Stock to be provided for
the purpose of conversion of Notes hereunder require registration with or
approval of any governmental authority under any federal or state law before
such shares may be validly issued upon conversion, the Company will in good
faith and as expeditiously as possible endeavor to secure such registration or
approval, as the case may be.

     The Company further covenants that if at any time the Common Stock shall be
listed on the New York Stock Exchange or any other national securities exchange
or automated quotation system the Company will, if permitted by the rules of
such exchange or automated quotation system, list and keep listed, so long as
the Common Stock shall be so listed on such exchange or automated quotation
system, all Common Stock issuable upon conversion of the Notes.

     Section 15.9   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 which may require any
adjustment of the Conversion

                                      -79-

<PAGE>

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, which 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
8.1, 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 Note for the purpose of conversion or to comply with any of the duties,
responsibilities or covenants of the Company contained in this Article.  Without
limiting the generality of the foregoing, neither the Trustee nor any conversion
agent shall be under any responsibility to determine the correctness of any
provisions contained in any supplemental indenture entered into pursuant to
Section 15.6 relating either to the kind or amount of shares of stock or
securities or property (including cash) receivable by Noteholders upon
the conversion of their Notes after any event referred to in such Section 15.6
or to any adjustment to be made with respect thereto, but, subject to the
provisions of Section 8.1, 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.

     Section 15.10  NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS.  In case:

          (a)  the Company shall declare a dividend (or any other distribution)
     on its Common Stock that would require an adjustment in the Conversion
     Price pursuant to Section 15.5; 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 share
     of any class or any other rights or warrants; or

          (c)  of any reclassification or reorganization of the Common Stock of
     the Company (other than a subdivision or combination of its outstanding
     Common Stock, or a change in par value, or from par value to no par value,
     or from no par value to par value), or of any consolidation or merger to
     which the Company is a party and for which approval of any shareholders of
     the Company is required, or of the 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;

                                      -80-

<PAGE>
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 provided for in
Section 2.5 of this Indenture, as promptly as possible but in any event at least
fifteen (15) days prior to the applicable date hereinafter specified, a notice
stating (x) the date on which a record is to be taken for the purpose of such
dividend, distribution or 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 or rights are to be determined, or (y) the date
on which such reclassification, consolidation, merger, sale, 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 Common Stock of record
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding-up.  Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such
dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up.

including under Sections 2.4, 2.5, 2.6, 2.7, 3.3 and 3.5, as 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 authentication and
delivery of such Notes "by the Trustee" and a certificate of authentication
executed on behalf of the Trustee by an

                                      -83-

<PAGE>

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 8.9.

     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 corporation is otherwise eligible under this
Section 16.11, 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
corporation.

     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 Trustee agrees to pay to the authenticating agent from time to time
reasonable compensation for its services (to the extent pre-approved by the
Company in writing), and the Trustee shall be entitled to be reimbursed for such
pre-approved payments, subject to Section 8.6.

     The provisions of Sections 8.2, 8.3, 8.4, 9.3 and this Section 16.11 shall
be applicable to any authenticating agent.

                            [FORM OF REVERSE OF NOTE]

                       National Semiconductor Corporation

                  6 1/2% CONVERTIBLE SUBORDINATED NOTE DUE 2002


     This Note is one of a duly authorized issue of Notes of the Company,
designated as its 6 1/2% Convertible Subordinated Notes due 2002 (herein called
the "Notes"), limited to the aggregate principal amount of $258,750,000, all
issued or to be issued under and pursuant to an Indenture dated as of September
15, 1995 (herein called the "Indenture"), between the Company and The First
National Bank of Boston, as trustee (herein called the "Trustee"), to which the
Indenture and all indentures supplemental thereto reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the holders of the Notes.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of 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 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 in the
Indenture provided, 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, HOWEVER, 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,
or impair or affect the right of any Noteholder 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 Note, or
modify the provisions of the Indenture with respect to the subordination of the
Notes in a manner adverse to the Noteholders in any material respect, or impair
or change the obligation of the Company to make redemption of any Note upon the
happening of a Fundamental Change in a manner adverse to the holder of the
Notes, or impair the right to convert the Notes into Common Stock subject to the
terms set forth in the Indenture, including Section 15.6 thereof, 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, prior to any
declaration accelerating the maturity of the Notes, 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

                                       -5-

<PAGE>

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 default in the payment of redemption price pursuant to Article III or a
failure by the Company to convert any Notes into Common Stock of the Company.
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 which may be
issued in exchange or substitute hereof, irrespective of whether or not any
notation thereof is made upon this Note or such other Notes.

     The indebtedness evidenced by the Notes is, to the extent and in the manner
provided in the Indenture, expressly subordinate and subject in right of payment
to the prior payment in full of all Senior Indebtedness of the Company, as
defined in the Indenture, whether outstanding at the date of the Indenture or
thereafter incurred, and this Note is issued subject to the provisions of the
Indenture with respect to such subordination.  Each holder of this Note, by
accepting the same, agrees to and shall be bound by such provisions and
authorizes the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination so provided and appoints the Trustee
his attorney-in-fact for such purpose.

     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 year of twelve
30-day months.

     The Notes are issuable in registered form without coupons in denominations
of $1,000 and any integral multiple of $1,000.  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 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 will not be redeemable at the option of the Company prior to
October 3, 1998.  On or after such date and prior to maturity the Notes may be
redeemed at the option of the Company as a whole, or from time to time in part,
upon mailing a notice of such redemption not less than 30 nor more than 60 days
before the date fixed for redemption to the holders of Notes at their last
registered addresses, all as provided in the Indenture, at the following
optional redemption prices (expressed as percentages of the principal amount),
together in each case with accrued interest to, but excluding, the date fixed
for redemption.

the holder of record on the next preceding March 15 or September 15,
respectively.

     The Notes are not subject to redemption through the operation of any
sinking fund.

     If a Fundamental Change (as defined in the Indenture) occurs at any time
prior to October 1, 2002, the Notes will be redeemable on the 30th day after
notice thereof at the option of the holder.  Such payment shall be made at the
following prices (expressed as percentages of the principal amount) in the event
of a Fundamental Change occurring during the 12-month period beginning October

and 100% at October 1, 2002; provided in each case that if the Applicable Price
(as defined in the Indenture) is less than the Reference Market Price (as
defined in the Indenture), the Company shall redeem such Notes at a price equal
to the foregoing repayment price multiplied by the fraction obtained by dividing
the Applicable Price by the Reference Market Price.  In each case, the Company
shall also pay accrued interest, if any, on such Notes to, but excluding, the
repayment date; PROVIDED that if such repayment date is April 1 or October 1,
then the interest payable on such date shall be paid to the holder of record of
the Note on the next preceding March 15 or September 15.  The Company shall mail
to all holders of record of the Notes a notice of the occurrence of a
Fundamental Change and of the redemption right arising as a result thereof on or
before the 10th day after the occurrence of such Fundamental Change.  For a Note
to be so repaid at the option of the holder, the Company must receive at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City

                                       -7-

<PAGE>

of New York, such Note with the form entitled "Option to Elect Repayment Upon a
Fundamental Change" on the reverse thereof duly completed, together with such
Notes duly endorsed for transfer, on or before the 30th day after the date of
such notice (or if such 30th day is not a Business Day, the immediately
preceding Business Day).

     Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after 60 days following original issuance of
the Notes and prior to the close of business on October 1, 2002, or, as to all
or any portion hereof called for redemption, prior to the close of business on
the Business Day immediately preceding 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 which is $1,000 or an integral
multiple thereof, into that number of 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
conversion price of $42.78 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, 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, HOWEVER, 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 to the close of business on the Business
Day preceding the interest payment date, this Note (unless it or the portion
being converted shall have been called for redemption during the period from the
close of business on any record date for the payment of interest to the close of
business on the Business Day preceding the interest payment date) must be
accompanied by an amount, in New York Clearing House funds or other funds
acceptable to the Company, equal to the interest payable on such interest
payment date on the principal amount being converted.  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 which would
otherwise be issuable upon the surrender of any Note or Notes for conversion.

     Any Notes called for redemption, unless surrendered for conversion on or
before the close of business on the date fixed for redemption, may be deemed to
be purchased from the holder of such Notes at an amount equal to the applicable
redemption price, together with accrued interest to the date fixed for
redemption, by one or more investment bankers or other purchasers who may agree
with the Company to purchase such Notes from the holders thereof and convert
them into Common Stock of the Company and to make payment for such Notes as
aforesaid to the Trustee in trust for such holders.

<PAGE>


     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, a new Note or Notes of authorized denominations for an equal aggregate
principal amount will be issued to the transferee in exchange thereof, subject
to the limitations provided in the Indenture, without charge except for any tax
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 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 other
authenticating agent nor any paying agent nor any other 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, employee, agent, officer or director or
subsidiary, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, 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.

     Terms used in this Note and defined in the Indenture are used herein as
therein defined.

days following the latest date of original issuance of the Notes (the "Filing
Date"), a Registration Statement for an offering to be made on a continuous
basis pursuant to Rule 415 of the Securities Act (a "Shelf Registration")
registering the resale from time to time by Holders thereof of all of the
Registrable Securities upon and following conversion of the Notes (the "Initial
Shelf Registration").   The Initial Shelf Registration shall be on Form S-3 or
another appropriate form permitting registration of such Registrable Securities
for resale by such Holders in the manner or manners designated by them
(including, without limitation, one or more Underwritten


                                       -4-
<PAGE>

Offerings).   The Company shall use its reasonable efforts to cause the Initial
Shelf Registration to be declared effective under the Securities Act as soon as
practicable and to keep the Initial Shelf Registration continuously effective
under the Securities Act until the earlier of the expiration of the
Effectiveness Period or the date a Subsequent Shelf Registration, as defined
below, covering all of the Registrable Securities has been declared effective
under the Securities Act.

          (b)  If the Initial Shelf Registration or any Subsequent Shelf
Registration, as defined below, ceases to be effective for any reason at any
time during the Effectiveness Period (other than because all Registrable
Securities registered thereunder shall have been sold or shall have ceased to be
Registrable Securities), the Company shall use its best efforts to obtain the
prompt withdrawal of any order suspending the effectiveness thereof, and in any
event shall within thirty (30) days of such cessation of effectiveness amend the
Shelf Registration in a manner reasonably expected to obtain the withdrawal of
the order suspending the effectiveness thereof, or file an additional Shelf
Registration covering all of the Registrable Securities (a "Subsequent Shelf
Registration").  If a Subsequent Shelf Registration is filed, the Company shall
use its best efforts to cause the Subsequent Shelf Registration to be declared
effective as soon as practicable after such filing and to keep such Registration
Statement continuously effective until the end of the Effectiveness Period.

          (c)  The Company shall supplement and amend the Shelf Registration if
required by the rules, regulations or instructions applicable to the
registration form used by the Company for such Shelf Registration, if required
by the Securities Act, or if reasonably requested by the Initial Purchasers or
by the Trustee on behalf of the Holders of the Registrable Securities covered by
such Registration Statement or by any Managing Underwriter of such Registrable
Securities.

          (d)  Each Holder of Registrable Securities agrees that if Holder
wishes to sell its Registrable Securities pursuant to a Shelf Registration and
related Prospectus, it will do so only in accordance with this Section 2(d).
Each Holder of Registrable Securities agrees to give written notice to the
Company at least three Business Days prior to any intended distribution of
Registrable Securities under the Shelf Registration, which notice shall specify
the date on which such Holder intends to begin such distribution and any
information with respect to such Holder and the intended distribution of
Registrable Securities by such Holder required to amend or supplement the
Registration Statement with respect to such intended distribution of Registrable
Securities by such Holder.   As soon as practicable after the date such notice
is provided, and in any event within two Business Days after such date, the
Company shall either:


                                       -5-
<PAGE>


               (i)   (A)  prepare and file with the Commission a post-effective
amendment to the Shelf Registration or a supplement to the related Prospectus or
a supplement or amendment to any document incorporated therein by reference or
file any other required document so that such Registration Statement will not
contain an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading, and so that, as thereafter delivered to purchasers of the
Registrable Securities being sold thereunder, such Prospectus will not contain
an untrue statement of a material fact or omit to state a material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading; (B) provide the
Holders of the Registrable Securities who gave such notice copies of any
documents filed pursuant to Section 2(d)(i)(A); and (C) inform each such Holder
that the Company has complied with its obligations in Section 2(d)(i)(A) (or
that, if the Company has filed a post-effective amendment to the Shelf
Registration which has not yet been declared effective, the Company will notify
each such Holder to that effect, will use its best efforts to secure the
effectiveness of such post-effective amendment and will immediately notify each
such Holder pursuant to Section 2(d)(i)(A) hereof when the amendment has become
effective); each Holder who has given notice of intention to distribute such
Holder's Registrable Securities in accordance with Section 2(d) hereof (a
"Notice Holder") will sell all or any or such Registrable Securities pursuant to
the Shelf Registration and related Prospectus only during the 45-day period
commencing with the date on which the Company gives notice, pursuant to Section
2(d)(i)(A), that the Registration Statement and Prospectus may be used for such
purpose (such 45-day period is referred to as a "Selling Period").   The Notice
Holders will not sell any Restricted Securities pursuant to such Registration
Statement or Prospectus after such Selling Period without giving a new notice of
intention to sell pursuant to Section 2(d) hereof and receiving a further notice
from the Company pursuant to Section 2(d)(i)(A) hereof.

               (ii)   in the event (A) of the happening of any event of the kind
described in Section 3(e)(ii), 3(e)(iii), 3(e)(iv), 3(e)(v) or 3(e)(vi) hereof
or (B) that, in the judgment of the Company, it is advisable to suspend use of
the Prospectus for a discrete period of time due to pending material corporate
developments or similar material events that have not yet been publicly
disclosed and as to which the Company believes public disclosure will be
prejudicial to the Company, the Company shall deliver a certificate in writing,
signed by its Chief Executive Officer, Chief Financial Officer or General
Counsel, to the Notice Holders, the Special Counsel and the Managing
Underwriters, if any, to the effect of the foregoing and, upon receipt of such
certificate, each such Notice Holder's Selling Period will not commence until


                                       -6-
<PAGE>

such Notice Holder's receipt of copies of the supplemented or amended Prospectus
provided for in Section 2(d)(i)(A) hereof, or until it is advised in writing by
the Company that the Prospectus may be used, and has received copies of any
additional or supplemental filings that are incorporated or deemed incorporated
by reference in such Prospectus.   The Company will use its best efforts to
ensure that the use of the Prospectus may be resumed, and the Selling Period
will commence, as soon as practicable and, in the case of a pending development
or event referred to in Section 2(d)(ii)(B) hereof, as soon as the earlier of
(x) public disclosure of such pending material corporate development or similar
material event or (y) in the judgment of the Company, public disclosure of such
material corporate development or similar material event would not be
prejudicial to the Company.   Notwithstanding the foregoing, the Company shall
not under any circumstances be entitled to exercise its right under this Section
2(d)(ii) to defer the commencement of a Selling Period more than one (1) time in
any three (3) month period or two (2) times in any twelve (12) month period, and
the period in which a Selling Period is suspended shall not exceed fifteen (15)
days unless the Company shall deliver to such Notice Holders a second notice to
the effect set forth above, which shall have the effect of extending the period
during which such Selling Period is deferred by up to an additional fifteen (15)
days, or such shorter period of time as is specified in such second notice.   In
no event shall the Company be permitted to extend the period during which such
Selling Period is deferred from and after the date a Notice Holder provides
notice to the Company in accordance with this Section 2(d) of its intention to
distribute Registrable Securities (a "Deferral Period") beyond such thirty (30)
day period.

          (e)  The parties hereto agree that the Holders of Registrable
Securities will suffer damages, and that it would not be feasible to ascertain
the extent of such damages with precision, if (i) the Initial Shelf Registration
has not been filed on or prior to the Filing Date, (ii) prior to the end of the
Effectiveness Period, the SEC shall have issued a stop order suspending the
effectiveness of the Shelf Registration or proceedings have been initiated with
respect to the Shelf Registration under Section 8(d) or 8(e) of the Securities
Act, (iii) the aggregate number of days in any one Deferral Period exceeds the
periods permitted pursuant to Section 2(d)(ii) hereof or (iv) the number of
Deferral Periods exceeds the number permitted pursuant to Section 2(d)(ii)
hereof (each of the events of a type described in any of the foregoing clauses
(i) through (iv) are individually referred to herein as an "Event", and the
Filing Date in the case of clause (i), the date on which the effectiveness of
the Shelf Registration has been suspended or proceedings with respect to the
Shelf Registration under Section 8(d) or 8(e) of the Securities Act have been
commenced in the case of clause (ii), the date on which the duration of a
Deferral Period exceeds the periods permitted by Section 2(d)(ii) hereof in the
case of clause (iii), and the date of the


                                       -7-
<PAGE>

commencement of a Deferral Period that causes the limit on the number of
Deferral Periods under Section 2(d)(ii) hereof to be exceeded in the case of
clause (iv), being referred to herein as an "Event Date").  Events shall be
deemed to continue until the "Event Termination" which shall be the following
dates with respect to the respective types of Events:  the date the Initial
Registration Statement is filed in the case of an Event of the type described in
clause (i), the date that all stop orders suspending effectiveness of the Shelf
Registration have been removed and the proceedings initiated with respect to the
Shelf Registration under Section 8(d) or (e) of the Securities Act have
terminated, as the case may be, in the case of Events of the types described in
clause (ii), termination of the Deferral Period which caused the periods
permitted by Section 2(d)(ii) to be exceeded in the case of the commencement of
an Event of the type described in clause (iii), and termination of the Deferral
Period the commencement of which caused the number of Deferral Periods permitted
by Section 2(d)(ii) to be exceeded in the case of Events of the type described
in clause (iv).

          Accordingly, upon the occurrence of any Event and until such time as
there are no Events which have occurred and are continuing (a "Damages Accrual
Period"), commencing on the Event Date on which such Damages Accrual Period
began, the Company agrees to pay, as liquidated damages, and not as a penalty,
an additional amount (the "Liquidated Damages Amount"):  (A)(i) to each holder
of a Note that is a Notice Holder, accruing at a rate equal to one-half of one
percent per annum (50 basis points) on the aggregate principal amount of Notes
held by such Notice Holder and (ii) to each holder of Common Stock that is a
Notice Holder, accruing at a rate equal to one-half of one percent per annum (50
basis points) calculated on an amount equal to the product of (x) the Conversion
Price (as defined in the Indenture), times (y) the number of shares of Common
Stock held by such holder; and (B) if the Damages Accrual Period continues for
in excess of thirty (30) days, from and after the end of such third (30) day
period until the end of the applicable Event Period, (i) to each holder of a
Note (whether or not a Notice Holder), accruing at a rate equal to one-half of
one percent per annum (50 basis points) on the aggregate principal amount of
Notes held by such holder and (ii) to each holder of Common Stock (whether or
not a Notice Holder), accruing at a rate equal to one-half of one percent per
annum (50 basis points) calculated on an amount equal to the product of (x) the
applicable Conversion Price (as defined in the Indenture), times (y) the number
of shares of Common Stock held by such holder.  Notwithstanding the foregoing,
no Liquidated Damages Amounts shall accrue under clause (A) for the preceding
sentence during any period for which Liquidated Damages Amounts accrue under
clause (B) of the foregoing sentence or as to any Registrable Securities from
and after the earlier of (x) the date such securities are no longer Registrable
Securities, and (y) expiration of the Effectiveness Period.  The rate


                                       -8-
<PAGE>

of accrual of the Liquidated Damages Amount with respect to any period shall not
exceed the rate provided for in this paragraph notwithstanding the occurrence of
multiple concurrent Events.

          The Company shall pay the liquidated damages due on any Notes or
Common Stock by depositing with the Trustee under the Indenture, in trust, for
the benefit of the holders of Notes or Common Stock or Notice Holder, as the
case may be, entitled thereto, at least one business day prior to the applicable
payment date, sums sufficient to pay the liquidated damages accrued or accruing
since the last preceding payment date through such payment date.  For these
purposes, subject to the proviso set forth in the next sentence, payment dates
will be the same dates as the interest payment dates with respect to the Notes
under the Indenture.   The Liquidated Damages Amount due shall be payable to the
holder of Registrable Securities entitled thereto on such payment date to the
holders of record thereof on the applicable record date (corresponding to the
record dates for interest payments on the Notes), provided that accrued
Liquidated Damages Amounts shall be paid on the applicable redemption date upon
the redemption of any Note (to the extent accrued with respect to such Note)
and, in the event of redemption of all Notes, shall also be paid on such
redemption date to the holders of Common Stock (to the extent accrued with
respect to such Common Stock).   The Trustee shall be entitled, on behalf of the
holders of Notes, Common Stock and Notice Holder, to seek any available remedy
for the enforcement of this Agreement, including for the payment of such
liquidated damages.  Notwithstanding the foregoing, the parties agree that the
sole damages payable for a violation of the terms of this Agreement with respect
to which liquidated damages are expressly provided shall be such liquidated
damages.  Nothing shall preclude a Notice Holder or holder of Registrable
Securities from pursuing or obtaining specific performance or other equitable
relief with respect to this Agreement.

     All of the Company's obligations set forth in this Section 2(e) which are
outstanding with respect to any Registrable Securities at the time such security
ceases to be a Registrable Security shall survive until such time as all such
obligations with respect to such security have been satisfied in full
(notwithstanding termination of the Agreement pursuant to Section 8(o)).

          The parties hereto agree that the liquidated damages provided for in
this Section 2(e) constitute a reasonable estimate of the damages that may be
incurred by holders of Registrable Securities (other than the Initial
Purchasers) by reason of the failure of the Shelf Registration to be filed or
declared effective or unavailable


                                       -9-

(absolutely or as a practical matter) for effecting resales of Registrable
Securities, as the case may be, in accordance with the provisions hereof.

     3.   REGISTRATION PROCEDURES.  In connection with the Company's
registration obligations under Section 2 hereof, the Company shall effect such
registrations to permit the sale of the Registrable Securities in accordance
with the intended method or methods of disposition thereof, and pursuant thereto
the Company shall as expeditiously as possible:

          (a)  Prepare and file with the SEC a Registration Statement or
Registration Statements on any appropriate form under the Securities Act
available for the sale of the Registrable Securities by the Holders thereof in
accordance with the intended method or methods of distribution thereof, and use
its reasonable efforts to cause each such Registration Statement to become
effective and remain effective as provided herein; PROVIDED, that before filing
any such Registration Statement or Prospectus or any amendments or supplements
thereto (other than documents that would be incorporated or deemed to be
incorporated therein by reference and that the Company is required by applicable
securities laws or stock exchange requirements to file) the Company shall
furnish to the Initial Purchasers, the Special Counsel and the Managing
Underwriters of such offering, if any, copies of all such documents proposed to
be filed, which documents will be subject to the review of the Initial
Purchasers, the Special Counsel and such Managing Underwriters, and the Company
shall not file any such Registration Statement or amendment thereto or any
Prospectus or any supplement thereto (other than such documents which, upon
filing, would be incorporated or deemed to be incorporated by reference therein
and that the Company is required by applicable securities laws or stock exchange
requirements to file) to which the Holders of a majority of the Registrable
Securities covered by such Registration Statement, the Initial Purchasers or the
Special Counsel shall reasonably object in writing within two full Business
Days.

          (b)  Prepare and file with the SEC such amendments and post-effective
amendments to each Registration Statement as may be necessary to keep such
Registration Statement continuously effective for the applicable period
specified in Section 2; cause the related Prospectus to be supplemented by any
required Prospectus supplement, and as so supplemented to be filed pursuant to
Rule 424 (or any similar provisions then in force) under the Securities Act; and
comply with the provisions of the Securities Act with respect to the disposition
of all securities covered by such Registration Statement during the applicable
period in accordance with the intended methods of disposition by the sellers
thereof set forth in such Registration Statement as so amended or such
Prospectus as so supplemented.


                                      -10-
<PAGE>

          (c)  Notify the selling Holders, the Initial Purchasers, the Special
Counsel and the Managing Underwriters, if any,  promptly, and (if requested by
any such person) confirm such notice in writing, (i) when a Prospectus, any
Prospectus supplement, a Registration Statement or a post-effective amendment to
a Registration Statement has been filed with the SEC, and, with respect to a
Registration Statement or any post-effective amendment, when the same has become
effective, (ii) of any request by the SEC or any other federal or state
governmental authority for amendments or supplements to a Registration Statement
or related Prospectus or for additional information, (iii) of the issuance by
the SEC or any other federal or state governmental authority of any stop order
suspending the effectiveness of a Registration Statement or the initiation or
threatening of any proceedings for that purpose, (iv) of the receipt by the
Company of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction or the initiation or threatening of any proceeding for such
purpose, (v) of the existence of any fact or happening of any event which makes
any statement of a material fact in such Registration Statement or related
Prospectus or any document incorporated or deemed to be incorporated therein by
reference untrue or which would require the making of any changes in the
Registration Statement or Prospectus in order that, in the case of the
Registration Statement, it will not contain any 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 not misleading, and that in the case of
the Prospectus, it will not contain any untrue statement of a material fact or
omit to state any 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, and (vi) of the
Company's determination that a post-effective amendment to a Registration
Statement would be appropriate.

          (d)  Use its best efforts to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement, or the lifting of any
suspension of the qualification (or exemption from qualification) of any of the
Registrable Securities for sale in any jurisdiction, at the earliest possible
moment.

          (e)  If reasonably requested by the Initial Purchasers, the Special
Counsel, the Managing Underwriters, if any, or the Holders of a majority of the
Registrable Securities being sold, (i) promptly incorporate in a Prospectus
supplement or post-effective amendment to a Registration Statement such
information as the Initial Purchaser, the Special Counsel, the Managing
Underwriters, if any, or such Holders, in connection with any offering of
Registrable Securities, agree should be included therein as required by
applicable law, and (ii) make all required filings of


                                      -11-
<PAGE>

such Prospectus supplement or such post-effective amendment as soon as
practicable after the Company has received notification of the matters to be
incorporated in such Prospectus supplement or post-effective amendment;
PROVIDED, that the Company shall not be required to take any actions under this
Section 3(e) that are not, in the reasonable opinion of counsel for the Company,
in compliance with applicable law.

          (f)  Furnish to each selling Holder, the Special Counsel and the
Initial Purchasers, and each Managing Underwriter, if any, without charge, at
least one conformed copy of the Registration Statement or Statements and any
amendment thereto, including financial statements but excluding schedules, all
documents incorporated or deemed to be incorporated therein by reference and all
exhibits (unless requested in writing by such holder, counsel, Initial
Purchasers or underwriter).

          (g)  Deliver to each selling Holder, the Special Counsel and the
Initial Purchasers and each Managing Underwriter, if any, in connection with any
offering of Registrable Securities, without charge, as many copies of the
Prospectus or Prospectuses relating to such Registrable Securities (including
each preliminary prospectus) and any amendment or supplement thereto as such
persons may reasonably request; and the Company hereby consents to the use of
such Prospectus or each amendment or supplement thereto by each of the selling
Holders of Registrable Securities and the Underwriters, if any, in connection
with any offering and sale of the Registrable Securities covered by such
Prospectus or any amendment or supplement thereto.

          (h)  Prior to any public offering of Registrable Securities, to
register or qualify or cooperate with the selling Holders, the Managing
Underwriters, if any, and the Special Counsel in connection with the
registration or qualification (or exemption from such registration or
qualification) of such Registrable Securities for offer and sale under the
securities or Blue Sky laws of such jurisdictions within the United States as
any selling Holder or Managing Underwriter reasonably requests in writing; keep
each such registration or qualification (or exemption therefrom) effective
during the period such Registration Statement is required to be kept effective
and do any and all other acts or things necessary or advisable to enable the
disposition in such jurisdictions of the Registrable Securities covered by the
applicable Registration Statement; PROVIDED, that the Company will not be
required to (i) qualify generally to do business in any jurisdiction where it is
not then so qualified or (ii) take any action that would subject it to general
service of process in suits or to taxation in any such jurisdiction where it is
not then so subject.


                                      -12-
<PAGE>

          (i)  Cause the Registrable Securities covered by the applicable
Registration Statement to be registered with or approved by such other
governmental agencies or authorities within the United States, except as may be
required solely as a consequence of the nature of such selling Holder, in which
case the Company will cooperate in all reasonable respects with the filing of
such Registration Statement and the granting of such approvals, as may be
necessary to enable the selling Holder or Holders thereof or the Managing
Underwriters, if any, to consummate the disposition of such Registrable
Securities.

          (j)  During any Selling Period (other than during a Deferral Period),
immediately upon the existence of any fact or the occurrence of any event as a
result of which a Registration Statement shall contain any 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 not misleading, or a Prospectus
shall contain any 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, promptly prepare and file a post-effective amendment to each
Registration Statement or a supplement to the related Prospectus or any document
incorporated therein by reference or file any other required document (such as a
Current Report on Form 8-K) that would be incorporated by reference into the
Registration Statement so that the Registration Statement shall not contain any
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 not misleading,
and so that the Prospectus will not contain any untrue statement of a material
fact or omit to state any 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, as
thereafter delivered to the purchasers of the Registrable Securities being sold
thereunder, and, in the case of a post-effective amendment to a Registration
Statement, use its best efforts to cause it to become effective as soon as
practicable.

          (k)  Enter into such agreements (including, in the event of an
Underwritten Offering, an underwriting agreement in form, scope and substance as
is customary in Underwritten Offerings) and take all such other actions in
connection therewith (including, in the event of an underwritten offering, those
reasonably requested by the Managing Underwriters, if any, or the Holders of a
majority of the Registrable Securities being sold) in order to expedite or
facilitate the disposition of such Registrable Securities and in such
connection, whether or not an underwriting agreement is entered into, and if the
registration is an underwritten registration, (i)


                                      -13-
<PAGE>

make such representations and warranties, subject to the Company's ability to do
so, to the Holders of such Registrable Securities and the underwriters with
respect to the business of the Company and its subsidiaries, the Registration
Statement, Prospectus and documents incorporated by reference or deemed
incorporated by reference, if any, in each case, in form, substance and scope as
are customarily made by issuers to underwriters in underwritten offerings and
confirm the same if and when requested; (ii) use its reasonable efforts to
obtain opinions of counsel to the Company and updates thereof (which counsel and
opinions (in form, scope and substance) shall be reasonably satisfactory to the
Managing Underwriters, if any, Special Counsel and the Holders of a majority of
the Registrable Securities being sold) addressed to each of the underwriters
covering the matters customarily covered in opinions requested in underwritten
offerings and such other matters as may be reasonably requested by such Special
Counsel and Managing Underwriters; (iii) use its reasonable efforts to obtain
"cold comfort" letters and updates thereof from the independent certified public
accountants of the Company (and, if necessary, any other certified public
accountants of any subsidiary of the Company or any business acquired or to be
acquired by the Company for which financial statements and financial data is, or
is required to be, included in the Registration Statement), addressed to each of
the Managing Underwriters, if any, such letters to be in customary form and
covering matters of the type customarily covered in "cold comfort" letters in
connection with Underwritten Offerings; and (iv) deliver such documents and
certificates as may be reasonably requested by the holders of a majority of the
Registrable Securities being sold, the Special Counsel and the Managing
Underwriters, if any, to evidence the continued validity of the representations
and warranties of the Company and its subsidiaries made pursuant to clause (i)
above and to evidence compliance with any customary conditions contained in the
underwriting agreement or other agreement entered into by the Company.   The
above shall be done at each closing under such underwriting or similar agreement
as and to the extent required thereunder.

          (l)  If requested in connection with a disposition of Registrable
Securities pursuant to a Registration Statement, make available for inspection
by a representative of the Holders of Registrable Securities being sold, any
Managing Underwriter participating in any disposition of Registrable Securities,
if any, and any attorney or accountant retained by such selling holders or
underwriter, financial and other records, pertinent corporate documents and
properties of the Company and its subsidiaries, and cause the executive
officers, directors and employees of the Company and its subsidiaries to supply
all information reasonably requested by any such representative, Managing
Underwriter, attorney or accountant in connection with such disposition; subject
to reasonable assurances by each such person that such


                                      -14-
<PAGE>


information will only be used in connection with matters relating to such
Registration Statement.

          (m)  Comply with all applicable rules and regulations of the SEC and
make generally available to its securityholders earning statements (which need
not be audited) satisfying the provisions of Section 11(a) of the Securities Act
and Rule 158 thereunder (or any similar rule promulgated under the Securities
Act) no later than 45 days after the end of any 12-month period (or 90 days
after the end of any 12-month period if such period is a fiscal year) (i)
commencing at the end of any fiscal quarter in which Registrable Securities are
sold to underwriters in a firm commitment or best efforts underwritten offering,
and (ii) if not sold to underwriters in such an offering, commencing on the
first day of the first fiscal quarter of the Company commencing after the
effective date of a Registration Statement, which statements shall cover said
12-month periods.

          (n)  Cooperate with the selling holders of Registrable Securities to
facilitate the timely preparation and delivery of certificates representing
Registrable Securities to be sold and not bearing any restrictive legends; and
enable such Registrable Securities to be in such denominations and registered in
such names as the holders may request.

          (o)  Provide a CUSIP number for all Registrable Securities not later
than the effective date of the Registration Statement and provide the Trustee
under the Indenture and the transfer agent for the Common Stock with printed
certificates for the Registrable Securities which are in a form eligible for
deposit with the Depository Trust Company.

          (p)  Cause all Registrable Securities covered by the Registration
Statement to be listed on each securities exchange or quotation system on which
the Company's Common Stock is then listed no later than the date the
Registration Statement is declared effective and, in connection therewith, to
the extent applicable, to make such filings under the Exchange Act (e.g., the
filing of a Registration Statement on Form 8-A) and to have such filings
declared effective thereunder.

          (q)  Cooperate and assist in any filings required to be made with the
National Association of Securities Dealers, Inc.

     4.   HOLDER'S OBLIGATIONS.  Each Holder agrees, by acquisition of the Notes
and Registrable Securities, that no Holder of Registrable Securities shall be
entitled to sell any of such Registrable Securities pursuant to a Registration
Statement or to


                                      -15-
<PAGE>

receive a Prospectus relating thereto, unless such Holder has furnished the
Company with the notice required pursuant to Section 2(d) hereof (including the
information required to accompany such notice) and, promptly after the Company's
request, such other information regarding such Holder and the distribution of
such Registrable Securities as the Company may from time to time reasonably
request.  The Company may exclude from such registration the Registrable
Securities of any Holder who does not furnish such information provided above
for so long as such information is not so furnished.  Each Holder of Registrable
Securities as to which any Registration Statement is being effected agrees
promptly to furnish to the Company all information required to be disclosed in
order to make the information previously furnished to the Company by such Holder
not misleading.  Any sale of any Registrable Securities by any Holder shall
constitute a representation and warranty by such Holder that the information
relating to such Holder and its plan of distribution is as set forth in the
Prospectus delivered by such Holder in connection with such disposition, that
such Prospectus does not as of the time of such sale contain any untrue
statement of a material fact relating to such Holder or its plan of distribution
and that such Prospectus does not as of the time of such sale omit to state any
material fact relating to such Holder or its plan of distribution necessary to
make the statements in such Prospectus, in light of the circumstances under
which they were made, not misleading.

     5.   REGISTRATION EXPENSES.  All fees and expenses incident to the
Company's performance of or compliance with this Agreement shall be borne by the
Company whether or not any of the Registration Statements become effective.
Such fees and expenses shall include, without limitation, (i) all registration
and filing fees (including, without limitation, fees and expenses (x) with
respect to filings required to be made with the National Association of
Securities Dealers, Inc. and (y) of compliance with federal securities or Blue
Sky laws (including, without limitation, fees and disbursements of Special
Counsel in connection with Blue Sky qualifications of the Registrable Securities
laws of such jurisdictions as the Managing Underwriters, if any, or Holders of a
majority of the Registrable Securities being sold may designate), (ii) printing
expenses (including, without limitation, expenses of printing certificates for
Registrable Securities in a form eligible for deposit with The Depository Trust
Company and of printing prospectuses if the printing of prospectuses is
requested by the Special Counsel or the holders of a majority of the Registrable
Securities included in any Registration Statement), (iii) messenger, telephone
and delivery expenses, (iv) reasonable fees and disbursements of counsel for the
Company and the Special Counsel in connection with the Shelf Registration
(provided that the Company shall not be liable for the fees and expenses of more
than one separate firm for all parties participating in any transaction
hereunder),  (v)


                                      -16-
<PAGE>

fees and disbursements of all independent certified public accountants referred
to in Section 3(k)(iii) hereof (including the expenses of any special audit and
"cold comfort" letters required by or incident to such performance) and (vi)
Securities Act liability insurance obtained by the Company in its sole
discretion.  In addition, the Company shall pay its internal expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expense of any annual
audit, the fees and expenses incurred in connection with the listing of the
securities to be registered on any securities exchange on which similar
securities issued by the Company are then listed and the fees and expenses of
any person, including special experts, retained by the Company.  Notwithstanding
the provisions of this Section 5, each seller of Registrable Securities shall
pay all registration expenses to the extent that the Company is prohibited by
applicable Blue Sky laws from paying for or on behalf of such seller of
Registrable Securities.

     6.   INDEMNIFICATION.

          (a)  INDEMNIFICATION BY THE COMPANY.  The Company shall indemnify and
hold harmless each Holder and each person, if any, who controls any Holder
(within the meaning of either Section 15 of the Securities Act or Section 20(a)
of the Exchange Act) from and against all losses, liabilities, claims, damages
and expenses (including, without limitation, any legal or other expenses
reasonably incurred in connection with defending or investigating any such
action or claim) (collectively, "Losses"), arising out of or based upon any
untrue statement or alleged untrue statement of a material fact contained in any
Registration Statement or Prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or based upon any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, except
insofar as such Losses arise out of or based upon the information relating to
any Holder furnished to the Company in writing by such Holder expressly for use
therein; PROVIDED, that the Company shall not be liable to any holder of
Registrable Securities (or any person controlling such Holder) to the extent
that any such Losses arise out of or are based upon an untrue statement or
alleged untrue statement or omission or alleged omission made in any preliminary
prospectus if either (A) (i) such Holder failed to send or deliver a copy of the
Prospectus with or prior to the delivery of written confirmation of the sale by
such Holder to the person asserting the claim from which such Losses arise and
(ii) the Prospectus would have corrected such untrue statement or alleged untrue
statement or such omission or alleged omission, or (B) (x) such untrue statement
or alleged untrue statement, omission or alleged omission is corrected in an
amendment or supplement to the Prospectus and (y) having previously been
furnished by or on behalf of the Company


                                      -17-
<PAGE>

with copies of the Prospectus as so amended or supplemented, such holder
thereafter fails to deliver such Prospectus as so amended or supplemented, with
or prior to the delivery of written confirmation of the sale of a Registrable
Security to the person asserting the claim from which such Losses arise.  The
Company shall also indemnify each underwriter and each person who controls such
person (within the meaning of Section 15 of the Securities Act or Section 20(a)
of the Exchange Act) to the same extent and with the same limitations as
provided above with respect to the indemnification of the holders of Registrable
Securities.

          (b)  INDEMNIFICATION BY HOLDER OF REGISTRABLE SECURITIES.  Each Holder
agrees severally and not jointly to indemnify and hold harmless the Company, its
directors, its officers who sign a Registration Statement, and each person, if
any, who controls the Company (within the meaning of either Section 15 of the
Securities Act or Section 20 of the Exchange Act), from and against all losses
arising out of or based upon any untrue statement of a material fact contained
in any Registration Statement, Prospectus or preliminary prospectus or arising
out of or based upon any omission of a material fact required to be stated
therein or necessary to make the statements therein not misleading, to the
extent, but only to the extent, that such untrue statement or omission is
contained in any information relating to such Holder so furnished in writing by
such Holder to the Company expressly for use in such Registration Statement or
Prospectus.  In no event shall the liability of any selling holder of
Registrable Securities hereunder be greater in amount than the dollar amount of
the proceeds received by such holder upon the sale of the Registrable Securities
giving rise to such indemnification obligation.

          (c)  CONDUCT OF INDEMNIFICATION PROCEEDINGS.  In case any proceeding
(including any governmental investigation) shall be instituted involving any
person in respect of which indemnity may be sought pursuant to either of the two
preceding paragraphs, such person (the "indemnified party") shall promptly
notify the person against whom such indemnity may be sought (the "indemnifying
party") in writing and the indemnifying party, upon request of the indemnified
party, shall retain counsel reasonably satisfactory to the indemnified party to
represent the indemnified party and any others the indemnifying party may
designate in such proceeding and shall pay the fees and disbursements of such
counsel related to such proceeding.  In any such proceeding, any indemnified
party shall have the right to retain its own counsel, but the fees and expenses
of such counsel shall be at the expense of such indemnified party unless (i) the
indemnifying party and the indemnified party shall have mutually agreed to the
retention of such counsel or (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same


                                      -18-
<PAGE>

counsel would be inappropriate due to actual or potential differing interests
between them.  It is understood that the indemnifying party shall not, in
respect of the legal expenses of any indemnified party in connection with any
proceeding or related proceedings in the same jurisdiction, be liable for (a)
the fees and expenses of more than one separate firm (in addition to any local
counsel) for all Holders and all persons, if any, who control any Holder within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act, and (b) the fees and expenses of more than one separate firm (in
addition to any local counsel) for the Company, its directors, its officers who
sign a Registration Statement and each person, if any, who controls the Company
within the meaning of either such Section, and that all such fees and expenses
shall be reimbursed as they are incurred.  In the case of any such separate firm
for the Company, and such directors, officers and control persons of the
Company, such firm shall be designated in writing by the Company.  The
indemnifying party shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent or if
there be a final judgment for the plaintiff, the indemnifying party agrees to
indemnify the indemnified party from and against any loss or liability by reason
of such settlement or judgment.   Notwithstanding the foregoing sentence, if at
any time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel as contemplated
by the second and third sentences of this paragraph, the indemnifying party
agrees that it shall be liable for any settlement of any proceeding effected
without its written consent if (i) such settlement is entered into more than 30
days after receipt by such indemnifying party of the aforesaid request and (ii)
such indemnifying party shall not have reimbursed the indemnified party in
accordance with such request prior to the date of such settlement.  No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in respect
of which any indemnified party is or could have been a party and indemnity could
have been sought hereunder by such indemnified party, unless such settlement
includes an unconditional release of such indemnified party from all liability
on claims that are the subject matter of such proceeding.

          (d)  CONTRIBUTION.  If the indemnification provided for in this
Section 6 is unavailable to an indemnified party under Section 6(a) or 6(b)
hereof in respect of any Losses or is insufficient to hold such indemnified
party harmless, then each applicable 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 indemnifying party
or parties on the one hand and the indemnified party or parties on the other
hand or (ii) if the allocation provided by clause (i) above


                                      -19-
<PAGE>

is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the indemnifying party or parties on the one hand and of
the indemnified party or parties on the other hand in connection with the
statements or omissions that resulted in such Losses, as well as any other
relevant equitable considerations.  Benefits received by the Company shall be
deemed to be equal to the total net proceeds from the initial placement (before
deducting expenses) of the Notes pursuant to the Placement Agreement. Benefits
received by the Initial Purchasers shall be deemed to be equal to the total
purchase discounts and commissions received by them pursuant to the Placement
Agreement and benefits received by any other Holders shall be deemed to be equal
to the value of receiving Notes registered under the Securities Act.  Benefits
received by any underwriter shall be deemed to be equal to the total
underwriting discounts and commissions, as set forth on the cover page of the
Prospectus forming a part of the Registration Statement which resulted in such
Losses.  The relative fault of the Holders on the one hand and the Company on
the other hand 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
Holders or by the Company and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Holders' respective obligations to contribute pursuant to this paragraph are
several in proportion to the respective number of Registrable Securities they
have sold pursuant to a Registration Statement, and not joint

     The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6(d) were determined by PRO RATA
allocation or by any other method or allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an indemnified party as a result of the Losses
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim.  Notwithstanding this Section 6(d), an
indemnifying party that is a selling Holder of Registrable Securities shall not
be required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities sold by such indemnifying party and
distributed to the public were offered to the public exceeds the amount of any
damages which such indemnifying party has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission.  No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of


                                      -20-
<PAGE>

the Securities Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.

     The indemnity, contribution and expense reimbursement obligations of the
Company hereunder shall be in addition to any liability the Company may
otherwise have hereunder, under the Placement Agreement or otherwise.  The
provisions of this Section 6 shall survive so long as Registrable Securities
remain outstanding, notwithstanding any transfer of the Registrable Securities
by any holder or any termination of this Agreement.

     The indemnity and contribution provisions contained in this Section 6 shall
remain operative and in full force and effect regardless of (i) any termination
of this Agreement, (ii) any investigation made by or on behalf of any Holder or
any person controlling any Holder, or the Company, its officers or directors or
any person controlling the Company and (iii) the sale of any Registrable
Securities by any Holder.

     7.   INFORMATION REQUIREMENTS.

          (a)  The Company shall file the reports required to be filed by it
under the Securities Act and the Exchange Act, and if at any time the Company is
not required to file such reports, it will, upon the request of any holder of
Registrable Securities, make publicly available other information so long as
necessary to permit sales pursuant to Rule 144 and Rule 144A under the
Securities Act.  The Company further covenants that it will cooperate with any
holder of Registrable Securities and take such further reasonable action as any
holder of Registrable Securities may reasonably request (including, without
limitation making such reasonable representations as any such holder may
reasonably request), all to the extent required from time to time to enable such
holder to sell Registrable Securities without registration under the Securities
Act within the limitation of the exemptions provided by Rule 144 and Rule 144A
under the Securities Act.  Upon the request of any holder of Registrable
Securities, the Company shall deliver to such holder a written statement as to
whether it has complied with such filing requirements.  Notwithstanding the
foregoing, nothing in this Section 7 shall be deemed to require the Company to
register any of its securities under any section of the Exchange Act.

          (b)  The Company shall file the reports required to be filed by it
under the Exchange Act and shall comply with all other requirements set forth in
the instructions to Form S-3 in order to allow the Company to be eligible to
file registration statements on Form S-3 after September 30, 1995.

     8.   MISCELLANEOUS.

          (a)  REMEDIES.  In the event of a breach by the Company of its
obligations under this Agreement, each holder of Registrable Securities, in
addition to being entitled to exercise all rights granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under this Agreement, PROVIDED that the sole damages payable for a violation of
the terms of this Agreement for which liquidated damages are expressly provided
pursuant to Section 2(e) hereof shall be such liquidated damages.  The Company
agrees that monetary damages would not be adequate compensation for any loss
incurred by reason of a breach by it of any of the provisions of this Agreement
and hereby further agrees that, in the event of any action for specific
performance in respect of such breach, it shall waive the defense that a remedy
at law would be adequate.

          (b)  NO CONFLICTING AGREEMENTS.  The Company has not, as of the date
hereof, and shall not, on or after the date of this Agreement, enter into any
agreement with respect to its securities which conflicts with the rights granted
to the holders of Registrable Securities in this Agreement.  The Company
represents and warrants that the rights granted to the holders of Registrable
Securities hereunder do not in any way conflict with the rights granted to the
holders of the Company's securities under any other agreements.

          (c)  AMENDMENTS AND WAIVERS.  The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the Company has obtained the written consent of holders
of a majority of the then outstanding Common Stock constituting Registrable
Securities (with holders of Notes deemed to be the holders, for purposes of this
Section, of the number of outstanding shares of Common Stock into which such
Notes are convertible).  Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of holders of Registrable Securities whose securities
are being sold pursuant to a Registration Statement and that does not directly
or indirectly affect the rights of other holders of Registrable Securities may
be given by holders of at least a majority of the Registrable Securities being
sold by such holders; PROVIDED, that the provisions of this sentence may not be
amended, modified, or supplemented except in accordance with the provisions of
the immediately preceding sentence.

          (d)  NOTICES.  All notices and other communications provided for or
permitted hereunder shall be made in writing and shall be deemed given (i) when

defined in Rule 405 under the Securities Act) (other than the Initial Purchasers
or subsequent holders of Registrable Securities if such subsequent holders are
deemed to be such affiliates solely by reason of their holdings of such
Registrable Securities) shall not be counted in determining whether such consent
or approval was given by the holders of such required percentage.

          (g)  SUCCESSORS AND ASSIGNS.   Any person who purchases any
Registerable Securities from an Initial Purchaser shall be deemed, for purposes
of this Agreement, to be an assignee of such Initial Purchaser.  This Agreement

                       National Semiconductor Corporation

                  6-1/2% CONVERTIBLE SUBORDINATED NOTE DUE 2002


     This Note is one of a duly authorized issue of Notes of the Company,
designated as its 6-1/2% Convertible Subordinated Notes due 2002 (herein called
the "Notes"), limited to the aggregate principal amount of $258,750,000, all
issued or to be issued under and pursuant to an Indenture dated as of September
15, 1995 (herein called the "Indenture"), between the Company and The First
National Bank of Boston, as trustee (herein called the "Trustee"), to which the
Indenture and all indentures supplemental thereto reference is hereby made for a
description of the rights, limitations of rights, obligations, duties and
immunities thereunder of the Trustee, the Company and the holders of the Notes.

     In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of 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 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 in the
Indenture provided, 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, HOWEVER, 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,
or impair or affect the right of any Noteholder 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 Note, or
modify the provisions of the Indenture with respect to the subordination of the
Notes in a manner adverse to the Noteholders in any material respect, or impair
or change the obligation of the Company to make redemption of any Note upon the
happening of a Fundamental Change in a manner adverse to the holder of the
Notes, or impair the right to convert the Notes into Common Stock subject to the
terms set forth in the Indenture, including Section 15.6 thereof, 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, prior to any
declaration accelerating the maturity of the Notes, 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

                                       -5-

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 default in the payment of redemption price pursuant to Article III or a
failure by the Company to convert any Notes into Common Stock of the Company.
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 which may be
issued in exchange or substitute hereof, irrespective of whether or not any
notation thereof is made upon this Note or such other Notes.

     The indebtedness evidenced by the Notes is, to the extent and in the manner
provided in the Indenture, expressly subordinate and subject in right of payment
to the prior payment in full of all Senior Indebtedness of the Company, as
defined in the Indenture, whether outstanding at the date of the Indenture or
thereafter incurred, and this Note is issued subject to the provisions of the
Indenture with respect to such subordination.  Each holder of this Note, by
accepting the same, agrees to and shall be bound by such provisions and
authorizes the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination so provided and appoints the Trustee
his attorney-in- fact for such purpose.

     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 year of twelve
30-day months.

     The Notes are issuable in registered form without coupons in denominations
of $1,000 and any integral multiple of $1,000.  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 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 will not be redeemable at the option of the Company prior to
October 3, 1998.  On or after such date and prior to maturity the Notes may be
redeemed at the option of the Company as a whole, or from time to time in part,
upon mailing a notice of such redemption not less than 30 nor more than 60 days
before the date fixed for redemption to the holders of Notes at their last
registered addresses, all as provided in the Indenture, at the following
optional redemption prices (expressed as percentages of the principal amount),
together in each case with accrued interest to, but excluding, the date fixed
for redemption.

the holder of record on the next preceding March 15 or September 15,
respectively.

     The Notes are not subject to redemption through the operation of any
sinking fund.


     If a Fundamental Change (as defined in the Indenture) occurs at any time
prior to October 1, 2002, the Notes will be redeemable on the 30th day after
notice thereof at the option of the holder.  Such payment shall be made at the
following prices (expressed as percentages of the principal amount) in the event
of a Fundamental Change occurring during the 12-month period beginning October
1:

and 100% at October 1, 2002; provided in each case that if the Applicable Price
(as defined in the Indenture) is less than the Reference Market Price (as
defined in the Indenture), the Company shall redeem such Notes at a price equal
to the foregoing repayment price multiplied by the fraction obtained by dividing
the Applicable Price by the Reference Market Price.  In each case, the Company
shall also pay accrued interest, if any, on such Notes to, but excluding, the
repayment date; PROVIDED that if such repayment date is April 1 or October 1,
then the interest payable on such date shall be paid to the holder of record of
the Note on the next preceding March 15 or September 15.  The Company shall mail
to all holders of record of the Notes a notice of the occurrence of a
Fundamental Change and of the redemption right arising as a result thereof on or
before the 10th day after the occurrence of such Fundamental Change.  For a Note
to be so repaid at the option of the holder, the Company must receive at the
office or agency of the Company maintained for that purpose in the Borough of
Manhattan, The City

                                       -7-
<PAGE>

of New York, such Note with the form entitled "Option to Elect Repayment Upon a
Fundamental Change" on the reverse thereof duly completed, together with such
Notes duly endorsed for transfer, on or before the 30th day after the date of
such notice (or if such 30th day is not a Business Day, the immediately
preceding Business Day).

     Subject to the provisions of the Indenture, the holder hereof has the
right, at its option, at any time after 60 days following original issuance of
the Notes and prior to the close of business on October 1, 2002, or, as to all
or any portion hereof called for redemption, prior to the close of business on
the Business Day immediately preceding 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 which is $1,000 or an integral
multiple thereof, into that number of 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
conversion price of $42.78 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, 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, HOWEVER, 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 to the close of business on the Business
Day preceding the interest payment date, this Note (unless it or the portion
being converted shall have been called for redemption during the period from the
close of business on any record date for the payment of interest to the close of
business on the Business Day preceding the interest payment date) must be
accompanied by an amount, in New York Clearing House funds or other funds
acceptable to the Company, equal to the interest payable on such interest
payment date on the principal amount being converted.  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 which would
otherwise be issuable upon the surrender of any Note or Notes for conversion.

     Any Notes called for redemption, unless surrendered for conversion on or
before the close of business on the date fixed for redemption, may be deemed to
be purchased from the holder of such Notes at an amount equal to the applicable
redemption price, together with accrued interest to the date fixed for
redemption, by one or more investment bankers or other purchasers who may agree
with the Company to purchase such Notes from the holders thereof and convert
them into Common Stock of the Company and to make payment for such Notes as
aforesaid to the Trustee in trust for such holders.

     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, a new Note or Notes of authorized denominations for an equal aggregate
principal amount will be issued to the transferee in exchange thereof, subject
to the limitations provided in the Indenture, without charge except for any tax
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 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 other
authenticating agent nor any paying agent nor any other 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, employee, agent, officer or director or
subsidiary, as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, 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.

     Terms used in this Note and defined in the Indenture are used herein as
therein defined.

    Re:  Registration Statement on Form S-3 of
         6,048,387 Shares of Common Stock, par value $0.50 per share
         -----------------------------------------------------------


Ladies and Gentlemen:

   In connection with the registration of 6,048,387 shares of common stock of
National Semiconductor Corporation, a Delaware corporation (the "Company"),
par value $0.50 per share (the "Shares"), under the Securities Act of 1933,
as amended (the "Act"), by the Company, pursuant to a Registration
Statement on Form S-3 filed with the Securities and Exchange Commission (the
"Commission") on October 25, 1995 (the "Registration Statement"), you
have requested our opinion with respect to the matters set forth below. The
Shares are issuable upon the conversion of the Company's 6-1/2% Convertible
Subordinated Notes due 2002 issued pursuant to an Indenture dated September 15,
1995 (the "Indenture") between the Company and The First National Bank of
Boston.

   In our capacity as your counsel in connection with such registration, we
are familiar with the proceedings taken and proposed to be taken by the
Company in connection with the authorization, issuance and sale of the Shares
and, for the purposes of this opinion, have assumed such proceedings will be
timely completed in the manner presently proposed. In addition, we have made
such legal and factual examinations and inquiries, including an examination
of originals or copies certified or otherwise identified to our satisfaction
of such documents, corporate records and instruments, as we have deemed
necessary or appropriate for purposes of this opinion.

   In our examination, we have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals, and the
conformity to authentic original documents of all documents submitted to us
as copies.

   We are opining herein as to the effect on the subject transaction only of
the internal laws of the State of California and the General Corporation Law
of the State of Delaware, and we express no opinion with respect to the
applicability thereto, or the effect thereon, of the laws of any other
jurisdiction or in the case of Delaware, any other laws, or as to any matters
of municipal law or the laws of any other local agencies within any state.

   Subject to the foregoing, it is our opinion that the Shares have been duly
authorized, and, upon issuance, delivery and payment therefor in the manner
contemplated by the Registration Statement and the Indenture, will be validly
issued, fully paid and nonassessable.

   We consent to your filing this opinion as an exhibit to the Registration
Statement and to the reference to our firm contained under the heading "Legal
Opinion."


                                           Very truly yours,
