                FLOATING RATE SENIOR NOTE DUE SEPTEMBER 19, 2002

                                  GLOBAL NOTE

                                                                CUSIP 404119AB5

         HCA - THE HEALTHCARE COMPANY, a corporation duly organized and
existing under the laws of the State of Delaware (herein called the "Company,"
which term includes any successor corporation under the Indenture hereinafter
referred to), for value received, hereby promises to pay to Cede & Co., as the
nominee of The Depository Trust Company, or registered assigns, the principal
amount of One Hundred Million Dollars ($100,000,000), on September 19, 2002
(the "Maturity Date"), and to pay interest thereon from September 19, 2000 or
from the most recent Interest Payment Date to which interest has been paid or
duly provided for, quarterly in arrears on March 19, June 19, September 19 and
December 19 in each year, commencing December 19, 2000, at the rate of LIBOR
plus 1.50%, until the principal hereof is paid or made available for payment.

<PAGE>   2

         The calculation agent, initially the Trustee (hereinafter defined),
will calculate the interest rate on this Global Note. The interest rate will be
equal to LIBOR plus 1.50%. The interest rate in effect for the period from
September 19, 2000 to December 19, 2000, the initial Interest Reset Date (as
defined below), will be LIBOR, as determined on September 14, 2000, plus 1.50%
(the "Initial Interest Rate"). The calculation agent will reset the interest
rate on each Interest Payment Date (each such day an "Interest Reset Date").
The second London Business Day (as defined below) preceding an Interest Reset
Date will be the "Interest Determination Date" for that Interest Reset Date.
The interest rate in effect on each day that is not an Interest Reset Date will
be the interest rate determined as of the Interest Determination Date
pertaining to the immediately preceding Interest Reset Date. The interest rate
in effect on any day that is an Interest Reset Date will be the interest rate
determined as of the Interest Determination Date pertaining to that Interest
Reset Date, except that the interest rate in effect for the period from and
including September 19, 2000 to the first Interest Reset Date will be the
Initial Interest Rate. The amount of interest payable for any period will be
computed on the basis of a 360-day year for the actual number of days elapsed.
If any Interest Payment Date (other than the Stated Maturity hereof) would
otherwise be a day that is not a Business Day, the Interest Payment Date will
be postponed to the next succeeding Business Day. If the Stated Maturity hereof
is not a Business Day, then payment of principal and interest payable on such
date will be made on the next succeeding day which is a Business Day (and
without any interest or other payment in respect of any such delay), in each
case with the same force and effect as if made on such date. A "Business Day"
shall mean any day, except a Saturday, a Sunday or a legal holiday in the City
of New York on which banking institutions are authorized or required by law,
regulation or executive order to close; provided that the day is also a London
Business Day. "London Business Day" means any day on which dealings in United
States dollars are transacted in the London interbank market.

         The calculation agent will determine "LIBOR" in accordance with the
following provisions:

         (i)      With respect to any Interest Determination Date, LIBOR will be
the rate for deposits in United States dollars having a maturity of three
months commencing on the first day of the applicable Interest Period that
appears on Telerate Page 3750 as of 11:00 a.m., London time, on that Interest
Determination Date. If no rate appears, LIBOR for that Interest Determination
Date will be determined in accordance with the provisions described in (ii)
below.

         (ii)     With respect to an Interest Determination Date on which no
rate appears on Telerate Page 3750, as specified in (i) above, the calculation
agent will request the principal London offices of each of four major reference
banks in the London interbank market, as selected by the calculation agent, to
provide the calculation agent with its offered quotation for deposits in United
States dollars for the period of three months, commencing on the first day of
the applicable Interest Period, to prime banks in the London interbank market
at approximately 11:00 a.m., London time, on that Interest Determination Date
and in a principal amount that is representative for a single transaction in
United States dollars in that market at that time. If at least two quotations
are provided, then LIBOR on that Interest Determination Date will be the
arithmetic mean of those quotations. If fewer than two quotations are provided,
then LIBOR on the Interest Determination Date will be the arithmetic mean of
the rates quoted at approximately

                                       2
<PAGE>   3

11:00 a.m., in the City of New York, on the Interest Determination Date by
three major banks in the City of New York selected by the calculation agent for
loans in United States dollars to leading European banks, having a three-month
maturity and in a principal amount that is representative for a single
transaction in United States dollars in that market at that time; provided,
however, that if the banks selected by the calculation agent are not providing
quotations in the manner described by this sentence, LIBOR determined as of
that Interest Determination Date will be LIBOR in effect on that Interest
Determination Date.

         "Telerate Page 3750" means the display designated as "Page 3750" on
Bridge Telerate, Inc., or any successor service, for the purpose of displaying
the London interbank rates of major banks for United States dollars.

         "Interest Period" means the period from and including September 19,
2000, to, and excluding, the first Interest Payment Date thereafter and then
from, and including, the immediately preceding Interest Payment Date to which
interest has been paid or duly provided for to, but excluding, the next
Interest Payment Date or the Maturity hereof, as the case may be.

         The interest so payable, and punctually paid or duly provided for, on
any Interest Payment Date will, as provided in such Indenture, be paid to the
Person in whose name this Global Note is registered at the close of business on
the Regular Record Date for such interest, which shall be the fifteenth
calendar day immediately preceding the Interest Payment Date (whether or not a
Business Day). Any such interest not so punctually paid or duly provided for
will forthwith cease to be payable to the Holder on such Regular Record Date
and may either be paid to the Person in whose name this Global Note is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 10 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the
Securities of this series may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in said Indenture.

         Both principal of (and premium, if any) and interest on this Global
Note are payable in immediately available funds in any coin or currency of the
United States of America, which at the time of payment is legal tender for the
payment of public and private debts. Payments of principal and interest will be
made in the City of New York, at the Corporate Trust Office of Bank One Trust
Company, N.A., or at such other office or agency of the Company as the Company
shall designate pursuant to the Indenture referred to elsewhere herein.

         This Global Note is one of a duly authorized issue of debentures,
notes, bonds or other evidences of indebtedness of the Company (the
"Securities"), of the series hereinafter specified, issued or to be issued
under an Indenture dated as of December 16, 1993, as supplemented, as may be
amended by indentures supplemental thereto (the "Indenture"), duly executed and
delivered by the Company to Bank One Trust Company, N.A., the successor to The
First National Bank of Chicago, as trustee (the "Trustee"), to which Indenture
reference is hereby made for a description of the respective rights and duties
thereunder of the Trustee, the Company and the Holders of the Securities and
the terms upon which the Securities are, and are to be,

                                       3

authenticated and delivered. The Securities may be issued in one or more
series, which different series may be issued in various aggregate principal
amounts, may mature at different times, may bear interest at different rates,
may have different conversion prices (if any), may be subject to different
redemption provisions, may be subject to different sinking, purchase or
analogous funds, may be subject to different covenants and Events of Default
and may otherwise vary as in the Indenture provided. This Global Note,
Certificate R6, along with Global Note, Certificate R5, together represent a
Global Security representing the entire principal amount of a series of
Securities designated "Floating Rate Senior Notes Due September 19, 2002" (the
"Notes") issued under the Indenture. Unless otherwise provided herein, all
terms used in this Global Note, which are defined in the Indenture, shall have
the meanings assigned to them in the Indenture.

         The Notes are not redeemable. The Notes do not have a sinking fund.

         In case an Event of Default with respect to the Notes shall have
occurred and be continuing, the principal hereof may be declared, and upon such
declaration shall become, immediately due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture. The Indenture
provides that such declaration may in certain events be waived by the Holders
of a majority in principal amount of the Notes then Outstanding.

         Several banks and other financial institutions have provided the
Company with a $1.2 billion credit facility under a term loan agreement dated
as of March 13, 2000, as amended. The Company will be in default under the
Notes if a default occurs under that agreement (as it may be amended, modified,
extended, renewed or replaced from time to time) and that default results in an
acceleration of the maturity of the Company's indebtedness under that
agreement. A declaration of the acceleration of the maturity of the Notes for
this reason is subject to annulment if the default that caused acceleration of
the indebtedness under the agreement is cured or waived. The Company does not
need the consent of the Holders of the Notes to enter into any amendment,
modification, extension, renewal or replacement of the term loan agreement.
Such cross-default will no longer be applicable following the time, if ever, as
the Notes are rated Baa3 (or the equivalent) or higher by Moody's and BBB- (or
the equivalent) or higher by Standard & Poor's. "Moody's" means Moody's
Investors Service, Inc. and its successors. "Standard & Poor's" means Standard
and Poor's Ratings Services, a division of The McGraw-Hill Companies, Inc., and
its successors.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of not less than a majority in principal amount of
the Outstanding Securities of each series to be affected. It is also provided
in the Indenture that, prior to any declaration accelerating the maturity of
the Notes as a series, the Holders of a majority in aggregate principal amount
of the Securities of such series at the time Outstanding may on behalf of the
Holders of all of the Securities of such series waive any past default with
respect to the Securities of such series under the Indenture and its
consequences, except a default in the payment of the principal of, or interest
on, any of the Securities of such series.

         No reference herein to the Indenture and no provision of this Global
Note or of the Indenture (including the Company's right to defease and
discharge the Notes pursuant to Article Four and Article Fourteen of the
Indenture) shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of, and interest on, this
Global Note at the place, at the respective times, at the rate and in the coin
or currency herein prescribed.

         This Global Note shall be exchangeable for Securities registered in
the names of Persons other than the Depositary or its nominee only if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as
the Depositary or if at any time the Depositary ceases to be registered or in
good standing under the United States Securities Exchange Act of 1934, as
amended, and the Company fails to appoint a successor Depositary within 90 days
after the Company receives such notice or becomes aware of such event, (ii) the
Company executes and delivers to the Trustee a Company Order that this Global
Note shall be so exchangeable or (iii) there shall have occurred and be
continuing an Event of Default, or an event which, with the giving of notice or
the lapse of time, or both, would constitute an Event of Default, with respect
to the Notes. To the extent that this Global Note is exchangeable pursuant to
the preceding sentence, it shall be exchangeable for Notes registered in such
names as the Depositary shall direct.

         Except as provided in the immediately preceding paragraph, this Global
Note may not be transferred except as a whole by the Depositary to a nominee of
such Depositary or by a nominee of such Depositary to such Depositary or
another nominee of such Depositary or by such Depositary or any such nominee to
a successor of such Depositary or a nominee of such successor.

         Prior to due presentment for registration of transfer of this Global
Note, the Company, the Trustee and any agent of the Company or the Trustee may
deem and treat the Holder hereof as the absolute owner of this Global Note
(whether or not this Global Note shall be overdue and notwithstanding any
notation of ownership or other writing hereon), for the purpose of receiving
payment hereof or on account hereof (except as otherwise provided in the
Indenture), as herein provided, and for all other purposes, and neither the
Company nor the Trustee nor any Paying Agent nor any Security Registrar shall
be affected by any notice to the contrary. All payments made to or upon the
order of such Holder shall, to the extent of the sum or sums paid, effectually
satisfy and discharge liability for moneys payable on this Global Note.

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of this Global Note or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

         No recourse for the payment of the principal of, or interest on, this
Global Note, or for any claims based hereon or otherwise in respect hereof, and
no recourse under or upon any obligation, covenant or agreement of the Company
in the Indenture or any indenture supplemental thereto or in any Note or
because of the creation of any indebtedness represented thereby, shall be had
against any incorporator, stockholder, officer or director, as such, past,
present or future, of the Company, whether by virtue of any assessment or
penalty or otherwise,

                                       5
<PAGE>   6

all such liability being, by the acceptance hereof and as part of the
consideration for the issue hereof, expressly waived and released.

         Except as otherwise expressly provided in this Global Note, this
Global Note shall in all respects be entitled to all benefits, and subject to
the same terms and conditions, as definitive registered securities
authenticated and delivered under the Indenture.

         The Indenture and this Global Note shall be governed by and construed
in accordance with the laws of the State of New York.

         This Global Note shall not be valid or become obligatory for any
purpose until the certificate of authentication hereon shall have been signed
by the Trustee under the Indenture referred to on the reverse hereof.

TRUSTEE'S CERTIFICATE

This is one of the Securities

referred to in the within-

BANK ONE TRUST COMPANY, N.A.,
as Trustee

By: /s/ Sandra Whalen
   ----------------------------------------
Title: Authorized Officer
      -------------------------------------Exhibit 4.1

                            SONIC AUTOMOTIVE, INC.
                            1997 STOCK OPTION PLAN

                    Amended and Restated as of June 5, 2000

      1. Purposes of Plan. The purposes of the Plan, which shall be known as the
Sonic Automotive, Inc. 1997 Stock Option Plan and is hereinafter referred to as
the "Plan", are (i) to provide incentives for key employees, directors,
consultants and other individuals providing services to Sonic Automotive, Inc.
(the "Company") and its subsidiaries and other related entities (each of which
is referred to herein as a "Subsidiary") by encouraging their ownership of the
Class A Common Stock, $.01 par value per share, of the Company (the "Stock") and
(ii) to aid the Company in retaining such key employees, directors, consultants
and other individuals upon whose efforts the Company's success and future growth
depends, and attracting other such employees, directors, consultants and other
individuals.

      2. Administration. The Plan shall be administered by a committee of the
Board of Directors of the Company or subcommittee thereof (the "Committee"). The
Committee shall be appointed from time to time by the Board of Directors of the
Company (the "Board of Directors") and shall consist of not fewer than two of
its members. In the event that no such Committee exists or is appointed, then
the powers to be exercised by the Committee hereunder shall be exercised by the
Board of Directors.

      For purposes of administration, the Committee, subject to the terms of the
Plan, shall have plenary authority to establish such rules and regulations, to
make such determinations and interpretations, and to take such other
administrative actions, as it deems necessary or advisable. All determinations
and interpretations made by the Committee shall be final, conclusive and binding
on all persons, including those granted options hereunder ("Optionees") and
their legal representatives and beneficiaries.

      Notwithstanding any other provisions of the Plan, the Committee may impose
such conditions on any options as may be required to satisfy the requirements of
Rule 16b-3 of the Securities Exchange Act of 1934, as amended (the "Act") or
Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code").

      The Committee shall hold its meetings at such times and places as it may
determine. A majority of its members shall constitute a quorum. All
determinations of the Committee shall be made by a majority of its members. Any
decision or determination reduced to writing and signed by all members shall be
as effective as if it had been made by a majority vote at a meeting duly called
and held. The Committee may appoint a secretary (who need not be a member of the
Committee). No member of the Committee shall be liable for any act or omission
with respect to his service on the Committee, if he acts in good faith and in a
manner he reasonably believes to be in or not opposed to the best interests of
the Company.

      3. Stock Available for Options. There shall be available for options under
the Plan a total of 6,000,000 shares of Stock, subject to any adjustments which
may be made pursuant to Section 5(f) hereof. Shares of Stock used for purposes
of the Plan may be either authorized and unissued shares, or previously issued
shares held in the treasury of the Company, or both. Shares of Stock covered by
options which have
<PAGE>
terminated or expired prior to exercise, or which have been tendered as payment
upon exercise of other options pursuant to Section 5(c), shall be available for
further option grants hereunder.

      4. Eligibility. Options under the Plan may be granted to key employees of
the Company or any Subsidiary, including officers or directors of the Company or
any Subsidiary, and to consultants and other individuals providing services to
the Company or any Subsidiary. On and after June 5, 2000, options may no longer
be granted under this Plan to "non-employee directors" within the meaning of
Rule 16b-3 of the Act. Options may be granted to eligible persons whether or not
they hold or have held options previously granted under the Plan or otherwise
granted or assumed by the Company; provided, however, that the maximum number of
shares of Stock with respect to which options may be granted under the Plan to
any person during any calendar year shall be 500,000 shares of Stock (subject to
adjustment in the same manner as provided in Section 5(f) with respect to shares
of Stock subject to options then outstanding). In selecting recipients for
options, the Committee may take into consideration any factors it may deem
relevant, including its estimate of the individual's present and potential
contributions to the success of the Company and its Subsidiaries. Service as a
director, officer or consultant of or to the Company or any Subsidiary shall be
considered employment for purposes of the Plan (and the period of such service
shall be considered the period of employment for purposes of Section 5(d) of the
Plan); provided, however, that incentive stock options may be granted under the
Plan only to an individual who is an "employee" (as such term is used in Section
422 of the Code) of the Company or a Subsidiary which constitutes a "subsidiary
corporation" within the meaning of Section 424(f) of the Code.

      5. Terms and Conditions of Options. The Committee shall, in its
discretion, prescribe the terms and conditions of the options to be granted
hereunder, which terms and conditions need not be the same in each case, subject
to the following:

            (a) Option Price. The price at which each share of Stock may be
      purchased upon exercise of an option granted under the Plan shall be
      determined by the Committee in its discretion, but shall not be less than
      the fair market value per share of Stock on the date of grant of the
      option. In the case of any option intended to be an incentive stock option
      granted to an individual owning (directly or by attribution as provided in
      Section 424(d) of the Code), on the date of grant, stock possessing more
      than 10% of the total combined voting power of all classes of stock of the
      Company or any Subsidiary (which individual shall hereinafter be referred
      to as a "10% Stockholder"), the price at which each share of Stock may be
      purchased upon exercise of the option shall not be less than 110% of the
      fair market value per share of Stock on the date of grant of the option.
      The date of the grant of an option shall be the date specified by the
      Committee in its grant of the option. Except as otherwise provided in
      Section 5(f) of this Plan, the option price of an outstanding option under
      this Plan may not be repriced. Notwithstanding the foregoing, an option
      may be granted with an exercise price lower than that set forth above if
      such option is granted pursuant to an assumption or substitution for
      another option in a manner satisfying the provisions of Section 424(a) of
      the Code.

             For purposes of this Section 5(a), "fair market value" shall mean
      the last sale price regular way on the last trading day prior to the date
      of option grant, or, in case no sales take place on such date, the average
      of the closing high bid and low asked prices regular way, in either case
      on the principal national securities exchange on which the Stock is listed
      or admitted to trading, or if the

                                      2
<PAGE>
      Stock is not listed or admitted to trading on any national securities
      exchange, the last sale price reported on the National Market System of
      the National Association of Securities Dealers Automated Quotation system
      ("NASDAQ") on such date, or the average of the closing high bid and low
      asked prices of the Stock in the over-the-counter market reported on
      NASDAQ on such date, as furnished to the Committee by any New York Stock
      Exchange member selected from time to time by the Committee for such
      purpose. If there is no bid or asked price reported on any such date, the
      fair market value shall be determined by the Committee in accordance with
      the regulations promulgated under Section 2031 of the Code, or by any
      other appropriate method selected by the Committee.

            (b) Option Period. The period for exercise of an option shall be
      determined by the Committee in its discretion but in no event shall the
      exercise period be more than ten years from the date of grant, or in the
      case of an option intended to be an incentive stock option granted to a
      10% Stockholder, more than five years from the date of grant. Options may,
      in the discretion of the Committee, be made exercisable in installments
      during the option period. Any shares not purchased on any applicable
      installment date may be purchased thereafter at any time before the
      expiration of the option period, subject to Section 5(d) below.

            (c) Exercise of Options. In order to exercise an option, the
      Optionee shall deliver to the Company written notice specifying the number
      of shares of Stock to be purchased, together with full payment of the
      purchase price therefor; provided that, for the purpose of assisting an
      Optionee to exercise an option, the Company may make loans to the Optionee
      or guarantee loans made by third parties to the Optionee, on such terms
      and conditions as the Board of Directors may authorize. The purchase price
      may be paid in (i) cash (or a certified or bank cashier's check payable to
      the order of the Company); (ii) shares of Stock owned by the Optionee,
      (iii) nonstatutory options granted under the Plan and held by the Optionee
      (provided, however, that the purchase price of Stock acquired under an
      incentive stock option may not be paid in options); or (iv) any
      combination of the foregoing methods. Shares of Stock tendered in payment
      on the exercise of an option shall be valued at their fair market value
      determined as described in Section 5(a) above, provided that the date of
      determination shall be the date of exercise. The fair market value of
      options tendered in payment upon exercise of other options shall be the
      fair market value of the underlying Stock, determined as aforesaid, less
      the total exercise price of the options. In addition, at the request of
      the Optionee, and subject to applicable laws and regulations, the Company
      may (but shall not be required to) cooperate in a "cashless exercise" of
      an option (i.e., the assignment to the Company of the proceeds from a sale
      of Stock acquired upon exercise of the option or from the proceeds of a
      loan from a brokerage firm). If the Optionee so requests, shares of Stock
      purchased upon exercise of an option may be issued in the name of the
      Optionee or another person. An Optionee shall have none of the rights of a
      stockholder until the shares of Stock are issued to him.

            (d)   Effect of Termination of Employment.

                  (i) An option may not be exercised after the Optionee has
            ceased to be in the employ of the Company or any Subsidiary for any
            reason other than the Optionee's death, Disability or Involuntary
            Termination Without Cause. A cessation of employment, for purposes
            of incentive stock options only, shall be deemed to occur on the
            ninety-first day of a leave of absence unless the Optionee's
            reemployment rights are guaranteed by law or by contract. "Cause"
            shall mean any act, action or series of acts or actions or any
            omission,

                                      3
<PAGE>
            omissions, or series of omissions which result in, or which have the
            effect of resulting in, (i) the commission of a crime by the
            Optionee involving moral turpitude, which crime has a material
            adverse impact on the Company or any Subsidiary or which is intended
            to result in the personal enrichment of the Optionee at the expense
            of the Company or one of its Subsidiaries, (ii) a material violation
            of the Optionee's responsibilities, or the Optionee's gross
            negligence or willful misconduct, or (iii) the continuous, willful
            failure of the person in question to follow the reasonable
            directives of the Board of Directors. "Disability" shall mean the
            inability or failure of a person to perform those duties for the
            Company or any Subsidiary traditionally assigned to and performed by
            such person because of the person's then-existing physical or mental
            condition, impairment or incapacity. The fact of disability shall be
            determined by the Committee, which may consider such evidence as it
            considers desirable under the circumstances, the determination of
            which shall be final and binding upon all parties. "Involuntary
            Termination Without Cause" shall mean either (i) the dismissal of,
            or the request for the resignation of, a person, by court order,
            order of any court- appointed liquidator or trustee of the Company,
            or the order or request of any creditors' committee of the Company
            constituted under the federal bankruptcy laws, provided that such
            order or request contains no specific reference to Cause; or (ii)
            the dismissal of, or the request for the resignation of, a person,
            by a duly constituted corporate officer of the Company or any
            Subsidiary, or by the Board, for any reason other than for Cause.

                  (ii) During the three months after the date of the Optionee's
            Involuntary Termination Without Cause, the Optionee shall have the
            right to exercise the options granted under the Plan, but only to
            the extent the options were exercisable on the date of the cessation
            of the Optionee's employment.

                  (iii) During the twelve months after the Optionee's employment
            with the Company or any Subsidiary ceases as a result of the
            Optionee's Disability, the Optionee shall have the right to exercise
            the options granted under the Plan, but only to the extent the
            options were exercisable on the date of the cessation of the
            Optionee's employment.

                  (iv) In the event of the death of the Optionee while employed
            or, in the event of the death of the Optionee after cessation of
            employment described in subparagraph (ii) or (iii), above, but
            within the three-month or twelve-month period described in
            subparagraph (ii) or (iii), above, the options granted under the
            Plan shall be exercisable until the expiration of twelve months
            following the Optionee's death, but only to the extent the option
            was exercisable on the date of the cessation of the Optionee's
            employment. During such extended period, the option may be exercised
            by the person or persons to whom the deceased Optionee's rights
            under the Option Agreement shall pass by will or by the laws of
            descent and distribution. The provisions of this subparagraph (iv)
            shall apply to any outstanding options which are incentive stock
            options to the extent permitted by Sections 421 and 422(d) of the
            Code and such outstanding options in excess thereof shall,
            immediately upon the death of the Optionee, be treated for all
            purposes of the Plan as nonstatutory stock options and shall be
            exercisable as such as provided in this subparagraph (iv).

            In no event shall any option be exercisable beyond the applicable
      exercise period determined pursuant to Section 5(b) of the Plan. Nothing
      in the Plan or in any option granted pursuant to the Plan (in the absence
      of an express provision to the contrary) shall confer on any individual
      any right to continue in the employ of the Company or any Subsidiary or
      interfere in any way with the right of the Company or Subsidiary to
      terminate his employment at any time.

                                      4

            (e) Nontransferability of Options. Except as otherwise set forth
      herein, during the lifetime of an Optionee, options held by such Optionee
      shall be exercisable only by him, and no option shall be transferable
      other than by will or the laws of descent and distribution.
      Notwithstanding the foregoing, the Committee, in its absolute discretion,
      may grant nonstatutory stock options that may be transferred without
      consideration, in whole or in part, by the Optionee to (i) the Optionee's
      child, stepchild, grandchild, parent, stepparent, grandparent, spouse,
      former spouse, sibling, niece, nephew, mother-in-law, father-in-law,
      son-in-law, daughter-in-law, brother-in-law or sister-in-law, including
      adoptive relationships, or any person sharing the Optionee's household
      (other than a tenant or employee) ("Family Members"); (ii) a trust in
      which Family Members have more than 50% of the beneficial interest; (iii)
      a foundation in which Family Members (or the Optionee) control the
      management of assets; or (iv) any other entity in which Family Members (or
      the Optionee) own more than 50% of the voting interests. In all cases, the
      Committee must be notified in advance in writing of the terms of any
      proposed transfer to a permitted transferee and such transfers may occur
      only with the consent of and subject to the rules and conditions imposed
      by the Committee. The transferee and the transferred options shall
      continue to be subject to the same terms and conditions as were applicable
      immediately prior to the transfer. The provisions of the Plan, including,
      but not limited to, those set forth in Section 5(b) and (d), shall
      continue to apply with respect to the Optionee and the option shall be
      exercisable by the transferee only to the extent and for the periods
      specified herein and in any applicable option agreement. The Optionee
      shall remain subject to withholding taxes upon exercise of any transferred
      option by the transferee.

            (f) Adjustments for Change in Stock Subject to Plan. In the event of
      a reorganization, recapitalization, stock split, stock dividend,
      combination of shares, merger, consolidation, rights offering or any other
      change in the corporate structure or shares of the Company, unless the
      Committee should determine otherwise, corresponding adjustments
      automatically shall be made to the number and kind of shares available for
      issuance under this Plan, the number and kind of shares covered by
      outstanding options under this Plan, and the exercise price per share for
      outstanding options. In addition, the Committee may make such other
      adjustments as it determines to be equitable.

            (g) Acceleration of Exercisability of Options Upon Occurrence of
      Certain Events. In connection with any merger or consolidation in which
      the Company is not the surviving corporation and which results in the
      holders of the outstanding voting securities of the Company (determined
      immediately prior to such merger or consolidation) owning less than a
      majority of the outstanding voting securities of the surviving corporation
      (determined immediately following such merger or consolidation), or any
      sale or transfer by the Company of all or substantially all of its assets
      or any tender offer or exchange offer for or the acquisition, directly or
      indirectly, by any person or group of all or a majority of the
      then-outstanding voting securities of the Company, all outstanding options
      under the Plan shall become exercisable in full, notwithstanding any other
      provision of the Plan or of any outstanding options granted thereunder, on
      and after (i) the fifteenth day prior to the effective date of such
      merger, consolidation, sale, transfer or acquisition or (ii) the date of
      commencement of such tender offer or exchange offer, as the case may be.
      The provisions of the foregoing sentence shall apply to any outstanding
      options which are incentive stock options to the extent permitted by
      Section 422(d) of the Code and such outstanding options in excess thereof
      shall, immediately upon the occurrence of the event described in clause
      (i) or (ii) of the foregoing sentence, be treated for all purposes of the
      Plan as nonstatutory stock options and shall be immediately exercisable as
      such

                                      5
<PAGE>
      as provided in the foregoing sentence. Notwithstanding the foregoing, in
      no event shall any option be exercisable after the date of termination of
      the exercise period of such option determined pursuant to Sections 5(b)
      and 5(d).

            (h) Registration, Listing and Qualification of Shares of Stock. Each
      option shall be subject to the requirement that if at any time the Board
      of Directors shall determine that the registration, listing or
      qualification of shares of Stock covered thereby upon any securities
      exchange or under any federal or state law, or the consent or approval of
      any governmental regulatory body, is necessary or desirable as a condition
      of, or in connection with, the granting of such option or the purchase of
      shares of Stock thereunder, no such option may be exercised unless and
      until such registration, listing, qualification, consent or approval shall
      have been effected or obtained free of any conditions not acceptable to
      the Board of Directors. The Company may require that any person exercising
      an option shall make such representations and agreements and furnish such
      information as it deems appropriate to assure compliance with the
      foregoing or any other applicable legal requirement.

            (i) Other Terms and Conditions. The Committee may impose such other
      terms and conditions, not inconsistent with the terms hereof, on the grant
      or exercise of options, as it deems advisable.

            (j) Reload Options. If upon the exercise of an option granted under
      the Plan (the "Original Option") the Optionee pays the purchase price for
      the Original Option pursuant to Section 5(c) in whole or in part in shares
      of Stock owned by the Optionee for at least six months, the Company shall
      grant to the Optionee on the date of such exercise an additional option
      under the Plan (the "Reload Option") to purchase that number of shares of
      Stock equal to the number of shares of Stock so held for at least six
      months transferred to the Company in payment of the purchase price in the
      exercise of the Original Option. The price at which each share of Stock
      covered by the Reload Option may be purchased shall be the market value
      per share of Stock (as specified in Section 5(c)) on the date of exercise
      of the Original Option. The Reload Option shall not be exercisable until
      one year after the date the Reload Option is granted or after the
      expiration date of the Original Option. Upon the payment of the purchase
      price for a Reload Option granted hereunder in whole or in part in shares
      of Stock held for more than six months pursuant to Section 5(c), the
      Optionee is entitled to receive a further Reload Option in accordance with
      this Section 5(j). Shares of Stock covered by a Reload Option shall not
      reduce the number of shares of Stock available under the Plan pursuant to
      Section 3.

      6. Additional Provisions Applicable to Incentive Stock Options. The
Committee may, in its discretion, grant options under the Plan which constitute
"incentive stock options" within the meaning of Section 422 of the Code to
eligible employees of the Company and its "subsidiary corporations" within the
meaning of Section 424(f) of the Code, provided, however, that the aggregate
market value of the Stock (determined as of the date the incentive stock option
is granted) with respect to which incentive stock options are exercisable for
the first time by the Optionee during any calendar year shall not exceed
$100,000 or such other limitation set forth in Section 422(d) of the Code.

                                      6

      7. Effectiveness of Plan. The Plan became effective when it was adopted
and approved by the Board of Directors and the stockholders of the Company on
October 9, 1997. The Plan was amended and restated effective as of December 3,
1998 and again amended and restated effective as of June 8, 1999; provided,
however, that the amendments to Section 5(e) contained in the June 8, 1999
restatement also shall apply to all outstanding nonstatutory stock options under
the Plan as of June 8, 1999. This amendment and restatement of the Plan shall be
effective as of June 5, 2000, subject to approval by the stockholders of the
Company at the 2000 Annual Meeting of Stockholders.

      8. Amendment and Termination. The Board of Directors may at any time amend
the Plan or the terms of any option outstanding under the Plan; provided,
however, that, except as contemplated in Section 5(f), the Board of Directors
shall not, without approval by a majority of the votes cast by the stockholders
of the Company at a meeting of stockholders at which a proposal to amend the
Plan is voted upon, (i) increase the maximum number of shares of Stock for which
options may be granted under the Plan, or (ii) except as otherwise provided in
the Plan, amend the requirements as to the class of employees eligible to
receive options. The Board of Directors may terminate the Plan at any time.
Unless the Plan shall theretofore have been terminated, the Plan shall
terminate, and no option shall be granted hereunder after, October 9, 2007. No
amendment or termination of the Plan or any option outstanding under the Plan
may, without the consent of an Optionee, adversely affect the rights of such
Optionee under any option held by such Optionee.

      9. Withholding. It shall be a condition to the obligation of the Company
to issue shares of Stock upon exercise of an option that the Optionee (or any
beneficiary or person entitled to act under Section 5(d) hereof) remit to the
Company, or make arrangements satisfactory to the Company to pay through payroll
withholding or otherwise, such amount as may be requested by the Company to meet
any federal, state or local tax withholding obligations with respect to such
exercise. If the amount requested is not paid, the Company may refuse to issue
such shares of Stock.

      10. Other Actions. Nothing contained in the Plan shall be construed to
limit the authority of the Company to exercise its corporate rights and powers,
including, but not by way of limitation, the right of the Company to grant or
assume options for proper corporate purposes other than under the Plan with
respect to any employee or other person, firm, corporation or association.
