                  INDENTURE SUPPLEMENT NO. 9 ("Indenture Supplement"), dated as
of January 11, 2002, between CENTEX CORPORATION, a Nevada corporation (together
with its successors and assigns as provided in the Indenture referred to below,
the "Company"), and JPMORGAN CHASE BANK, a New York banking corporation
(formerly, The Chase Manhattan Bank, successor to Chase Bank of Texas, National
Association) (together with its successors in trust thereunder as provided in
the Indenture referred to below, the "Trustee"), as trustee under an Indenture
dated as of October 1, 1998 (the "Indenture").

                              PRELIMINARY STATEMENT

                  Section 2.02 of the Indenture provides, among other things,
that the Company may, when authorized by its Board of Directors, and the Trustee
may at any time and from time to time, enter into a series supplement to the
Indenture for the purpose of authorizing one or more Series of Senior Debt
Securities and to specify certain terms of each such Series of Senior Debt
Securities. The Board of Directors of the Company has duly authorized the
creation of a Series of Senior Debt Securities to be known as the Company's
7 1/2% Notes due 2012 (the "Notes"), and the Company and the Trustee are
executing and delivering this Indenture Supplement in order to provide for the
issuance of the Notes.

                                   ARTICLE ONE

                                   Definitions

                  Except to the extent such terms are otherwise defined in this
Indenture Supplement or the context clearly requires otherwise, all terms used
in this Indenture Supplement which are defined in the Indenture or the form of
Note attached hereto as Exhibit A, either directly or by reference therein,
shall have the meanings assigned to them therein.

                  As used in this Indenture Supplement, the following terms
shall have the following meanings:

call for redemption or otherwise.

                  The term "Stated Maturity" means, when used with respect to

the date specified in such Note as the fixed date upon which the principal of
such Note or such installment of interest is due and payable.

                                   ARTICLE TWO

                         Terms and Issuance of the Notes

                  Section 2.01. Issuance and Designation. A Series of Senior
Debt Securities which shall be designated as the Company's "7 1/2% Notes due
2012" shall be executed, authenticated and delivered in accordance with the
provisions of, and shall in all respects be subject to, the terms, conditions
and covenants of, the Indenture and this Indenture Supplement (including the
form of Note set forth in Exhibit A). The aggregate principal amount of the
Notes which may be authenticated and delivered under this Indenture Supplement
shall not, except as permitted by the provisions of the Indenture, exceed
$350,000,000, provided that the Company may, without the consent of the Holders
of the Notes, reopen this Series and issue additional Notes under the Indenture
and this Indenture Supplement in addition to the $350,000,000 of Notes
authorized as of the date hereof.

                  Section 2.02. Form and Other Terms of Notes; Incorporation of
Terms. The Notes shall be substantially in the form attached hereto as Exhibit
A. The terms of such Notes are herein incorporated by reference and are part of
this Indenture Supplement.

                  Section 2.03. Place and Method of Payment. The place of
payment in respect of the Notes will be at the principal office or agency of the
Company in Dallas, Texas or at the office or place of business of the Trustee or
its successor in trust under the Indenture, which, at the date hereof, is
located at Chase Global Trust, 450 W. 33rd Street, 15th Floor, New York, New
York 10001. Payments in respect of principal or premium, if any, on Notes will
be made only against surrender of such Notes at such office. Payments of
interest on each Interest Payment Date with respect to each Note will be made to
the Person in whose name such Note is registered at the close of business on the
Regular Record Date immediately preceding such Interest Payment Date by U.S.
dollar check drawn on a bank in the City of New York or, for Holders of at least
$1,000,000 of Notes, by wire transfer to a dollar account maintained by the
payee with a bank in the United States; provided that a written request from
such Holder to such effect

                                       3
<PAGE>

designating such account is received by the Trustee or the Paying Agent no later
than 30 calendar days preceding such Interest Payment Date. Unless such
designation is revoked, any such designation made by such Holder with respect to
such Note payable to such Holder will remain in effect with respect to any
further interest payments with respect to such Note payable to such Holder. The
Company will pay any administrative costs imposed by banks in connection with
making interest payments by wire transfer.

                  So long as the Depositary continues to make its "Same-Day
Funds Settlement System" available to the Company, payments due on Notes
represented by a Global Security registered in the name of the Depositary or its
nominee will be made in immediately available funds to the Depositary or its
nominee, as the case may be, as the registered owner of the Global Security
representing such Notes. The Company expects that the Depositary or its nominee,
upon receipt of any payment, will credit immediately participants' accounts with
payments in same-day funds in amounts proportionate to their respective
beneficial interests in such payments, as shown on the records of the Depositary
or its nominee. The Company also expects that payments by participants and
indirect participants to owners of beneficial interests in such Global Security
held through such Persons will be governed by standing instructions and
customary practices, as is now the case with securities registered in the name
of nominees for such customers, and will be the responsibility of such
participants and indirect participants.

                                  ARTICLE THREE

                              Additional Covenants

                  Section 3.01. Limitation on Liens. The following provisions
shall apply to the Notes:

                  (a) The Company will not itself, and will not permit any of
         its subsidiaries (other than Centex Financial Services, Inc. and its
         subsidiaries) to, issue, assume or guarantee any indebtedness for
         borrowed money ("Indebtedness") if such borrowed money is secured by a
         mortgage, pledge, security interest, lien or other encumbrance (any
         such mortgage, pledge, security interest, lien or other encumbrance
         being hereinafter in this Section 3.01 referred to as a "Lien") on or
         with respect to any of the properties or assets of the Company or any
         such subsidiary or on any shares of capital stock or other equity
         interests of any subsidiary that owns properties or assets (other than
         Centex Financial Services, Inc. and its subsidiaries), whether, in each
         case, owned at the date of this Indenture Supplement or thereafter
         acquired, unless the Company makes effective provision whereby the
         Notes are secured by such Lien equally and ratably with any and all
         other borrowed money thereby secured; provided, however, that the
         foregoing restrictions shall not be applicable to:

                           (i) any Lien existing on any of the Company's
                  properties or assets or shares of capital stock or other
                  equity interests at the date of this Indenture Supplement;

                                       4
<PAGE>

                           (ii) any Lien created by a subsidiary of the Company
                  in favor of the Company or any wholly-owned subsidiary;

                           (iii) any Lien on any property or asset of any
                  corporation or other entity (or on any accession or
                  improvement to such asset or any proceeds thereof) existing at
                  the time such corporation or other entity becomes a subsidiary
                  of the Company or is merged or consolidated with or into the
                  Company or any of its subsidiaries;

                           (iv) any Lien on any property or asset existing at
                  the time of acquisition thereof (or on any accession or
                  improvement to such property or asset or any proceeds thereof)
                  by the Company or any of its subsidiaries;

                           (v) any Lien on any property or asset (or on any
                  accession or improvement to such property or asset or any
                  proceeds thereof) securing Indebtedness incurred or assumed
                  for the purpose of financing all or any part of the cost of
                  acquiring such property or asset or the making of any
                  improvement thereof; provided that such Lien attaches to such
                  property or asset concurrently with or within 180 days after
                  the acquisition thereof or the making of such improvement;

                           (vi) any Lien incurred in connection with pollution
                  control, industrial revenue or any similar financing;

                           (vii) any Lien arising out of the refinancing,
                  extension, renewal or replacement of any of the Liens
                  permitted by any of clauses (i) through (vi) above; provided
                  that the principal amount of the Indebtedness secured by the
                  Lien being refinanced, extended, reviewed or replaced is not
                  increased and is not secured by any additional properties or
                  assets; and

                           (viii) any Lien imposed by law.

                  (b) Notwithstanding the provisions of subsection (a) of this
         Section 3.01, the Company or any of its subsidiaries may issue, assume
         or guarantee Indebtedness secured by a Lien which would otherwise be
         subject to the foregoing restrictions in an aggregate amount which,
         together with all other such secured borrowings of the Company and its
         subsidiaries and the Attributable Debt (as defined below) in respect of
         Sale and Lease-Back Transactions (as defined in Section 3.02) existing
         at such time (other than Sale and Lease-Back Transactions not subject
         to the limitation contained in Section 3.02), does not at the time
         exceed twenty percent (20%) of the Consolidated Net Tangible Assets of
         the Company and its subsidiaries, as shown on the audited consolidated
         balance sheet contained in the latest annual report to stockholders of
         the Company. The term "Attributable Debt" as used in this paragraph
         shall mean, as of any particular time, the present value of the
         obligation of a lessee for rental payments during the remaining term of
         any lease (including any period for which such lease has been extended
         or may, at the option of the lessor, be extended).

<PAGE>

                  Section 3.02. Limitation on Sale and Lease-Back Transactions.
The Company will not, nor will it permit any of its subsidiaries to, enter into
any arrangement with any Person (other than the Company) providing for the
leasing by the Company or a subsidiary of any of its properties or assets
(except for temporary leases for a term of not more than three (3) years and
except for sales and leases of model homes), which property or asset has been or
is to be sold or transferred by the Company or such subsidiary to such Person
(herein referred to as a "Sale and Lease-Back Transaction"), unless (a) the net
proceeds to the Company or such subsidiary from such sale or transfer equal or
exceed the fair value (as determined by the Board of Directors, the Chairman of
the Board, the Vice Chairman, the President or the principal financial officer
of the Company) of the property or asset so leased, (b) the Company or such
subsidiary would be entitled to incur Indebtedness secured by a Lien on the
property or asset to be leased pursuant to Section 3.01, (c) the Company shall,
and in any such case the Company covenants that it will, apply an amount equal
to the fair value (as determined by the Board of Directors, the Chairman of the
Board, the Vice Chairman, the President or the principal financial officer of
the Company) of the property or asset so leased to the retirement (other than
any mandatory retirement), within 180 days of the effective date of any such
Sale and Lease-Back Transaction, of Funded Indebtedness of the Company, (d) such
Sale and Lease-Back Transaction relates to a sale which occurred within 180 days
from the date of acquisition of such property or asset by the Company or a
subsidiary or the date of the completion of construction or commencement of full
operations on such property, whichever is later, or (e) such transaction was
consummated prior to the date of this Indenture Supplement.

                                  ARTICLE FOUR

                                   Defeasance

                  Section 4.01. Option to Effect Legal Defeasance or Covenant
Defeasance. The Company may, at any time, with respect to the Notes, elect to
have either Section 13.01 of the Indenture or Section 4.03 of this Indenture
Supplement be applied to all outstanding Notes upon compliance with the
conditions set forth in Article Thirteen of the Indenture and below in this
Article Four.

                  Section 4.02. Legal Defeasance. Upon the Company's exercise
under Section 4.01 of the option applicable to Section 13.01 of the Indenture,
the Company may terminate its obligations under the Notes, the Indenture and
this Indenture Supplement by complying with the terms and conditions of Section
13.01 of the Indenture; provided, however, that the Opinion of Counsel delivered
to the Trustee will also state that either (A) the Company has received from, or
there has been published by, the Internal Revenue Service, a ruling or (B) since
the date hereof, there has been a change in the applicable federal income tax
law, in either case to the effect that, and based thereon such Opinion of
Counsel shall confirm that, the Holders of the outstanding Notes will not
recognize income, gain or loss for federal income tax purposes as a result of
such defeasance and will be subject to federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance had not occurred.

                                       6
<PAGE>

                  Section 4.03. Covenant Defeasance. Upon the Company's exercise
under Section 4.01 of the option applicable to this Section 4.03, the Company
shall be released from its obligations under the covenants contained in Article
Three of this Indenture Supplement with respect to the outstanding Notes on and
after the date the conditions set forth below are satisfied ("Covenant
Defeasance"), and the Notes shall thereafter be deemed not "outstanding" for the
purposes of any direction, waiver, consent or declaration or act of Holders (and
the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed "outstanding" for all other purposes hereunder (it being
understood that such Notes shall not be deemed outstanding for accounting
purposes). For this purpose, such Covenant Defeasance means that, with respect
to the outstanding Notes, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default, but, except as
specified above, the remainder of the Indenture and such Notes shall be
unaffected thereby. In addition, the Company's exercise under Section 4.01 of
the option applicable to this Section 4.03 shall not constitute an Event of
Default.

                  Section 4.04. Conditions to Covenant Defeasance. The following
shall be the conditions to the application of Section 4.03 to the outstanding
Notes:

                  (1) the Company shall irrevocably have deposited or caused to
         be deposited with the Trustee under the terms of an irrevocable trust
         agreement in form and substance satisfactory to the Trustee, as trust
         funds in trust solely for the benefit of the Holders of such Notes for
         that purpose, money or direct non-callable obligations of, or
         non-callable obligations guaranteed by, the United States of America
         for the payment of which guarantee or obligation the full faith and
         credit of the United States is pledged ("U.S. Government Obligations")
         maturing as to principal and interest in such amounts and at such times
         as are sufficient, as verified in a Certificate of a Firm of
         Independent Public Accountants, without consideration of any
         reinvestment of such interest, to pay principal of and interest on the
         outstanding Notes to maturity or redemption as the case may be,
         provided that the Trustee or any paying agent shall have been
         irrevocably instructed to apply such money or the proceeds of such U.S.
         Government Obligations to the payment of said principal and interest
         with respect to the Notes. The Company may make an irrevocable deposit
         pursuant to this Section 4.04 only if at such time the Company shall
         have delivered to the Trustee and any such paying agent an Officers'
         Certificate and an Opinion of Counsel, each stating that all conditions
         herein precedent to the satisfaction and discharge of this Indenture
         have been complied with and the Opinion of Counsel further states that
         the making of such deposit (i) does not contravene or violate any
         provision of any indenture, mortgage, loan agreement or other similar
         agreement known to such counsel to which the Company is a party or by
         which it or any of its property is bound, (ii) does not require
         registration by the deposit referred to above under the Investment
         Company Act of 1940, as amended, and (iii) to the effect that the
         Holders of the outstanding Notes will not recognize income, gain or
         loss for federal income tax purposes as a result of such defeasance and
         will be subject to federal income tax in the

         same amount, in the same manner and at the same times as would have
         been the case if such defeasance had not occurred.

                  (2) Notwithstanding the foregoing paragraph, the Company's
         obligations in Sections 2.06, 2.08, 5.01, 5.02, 5.05, 6.01, 8.06, 8.10,
         13.04 and 13.05 of the Indenture shall survive until the Notes are no
         longer outstanding. Thereafter, the Company's obligations in Sections
         8.06, 13.04 and 13.05 of the Indenture shall survive.

                  Centex Corporation, a corporation duly organized and existing

                            [FORM OF REVERSE OF NOTE]

                  This Note is one of a duly authorized issue of Senior Debt
Securities of the Company designated as its ___% Notes due 20__ (herein called
the "Notes"), issued and to be issued in one or more Series under an Indenture
dated as of October 1, 1998 (herein called the "Indenture") between the Company
and JPMorgan Chase Bank (f/k/a The Chase Manhattan Bank), as Trustee (herein
called the "Trustee," which term includes any successor Trustee under the
Indenture), to which Indenture and all indentures supplemental thereto
(including the Indenture Supplement dated as of _______ ___, 2002 which
authorizes the Notes) reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee and the Holders of the Notes, and of the terms upon which the Notes
are, and are to be, authenticated and delivered.

                  All terms used in this Note which are defined in the Indenture
or in any indenture supplemental thereto but are not defined in this Note shall
have the meanings assigned to them in the Indenture or in any indenture
supplemental thereto.

                  The indebtedness evidenced by the Notes is, to the extent and
in the manner provided in the Indenture and the Indenture Supplement, senior in
right of payment to certain indebtedness of the Company.

                  Interest on this Note will be payable on the Interest Payment
Date or Interest Payment Dates as specified on the face hereof and, in either
case, on the Maturity Date. Unless otherwise specified on the face hereof,
payments on this Note with respect to any particular Interest Payment Date or
the Maturity Date will include interest accrued from and including
______________, 2002, or from and including the most recent Interest Payment
Date to which interest has been paid or duly provided for, to but excluding the
particular Interest Payment Date or the Maturity Date. Interest on this Note
will be computed and paid on the basis of a 360-day year of twelve 30-day
months.

                  If an Interest Payment Date or the Maturity Date for this Note
falls on a day that is not a business day, payment of principal, premium, if
any, and interest to be made on such day with respect to this Note will be made
on the next succeeding day that is a business day with the same force and effect
as if made on the due date, and no additional interest will be payable on the
date of payment for the period from and after the due date as a result of such
delayed payment.

                  The Notes will be redeemable, in whole or in part, from time
to time at the option of the Company, on any date (a "Redemption Date") at a
redemption price equal to the greater of (a) 100% of the principal amount of the
Notes to be redeemed and (b) the sum of the present values of the Remaining
Scheduled Payments (as hereinafter defined) of principal and interest thereon
(exclusive of interest accrued to such Redemption Date) discounted to such
Redemption Date on a semiannual basis (assuming a 360-day year consisting of
twelve 30-day months) at the Treasury Rate (as hereinafter defined) plus ___
basis points, plus accrued and unpaid interest on the principal amount being
redeemed to such Redemption Date; provided, however, that installments of
interest on the Notes that are due and payable on an Interest Payment Date
falling on or prior to the relevant Redemption Date shall be payable to the
Holders of such Notes,

                                       4
<PAGE>

registered as such at the close of business on the relevant Regular Record Date
or Special Record Date, as the case may be, according to their terms and the
provisions of the Indenture.

                  "Comparable Treasury Issue" means the United States Treasury
security selected by the Independent Investment Banker (as hereinafter defined)
as having a maturity comparable to the remaining term of the Notes to be
redeemed that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities
of comparable maturity to the remaining term of the Notes.

                  "Comparable Treasury Price" means, with respect to any
Redemption Date, (1) the average of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
on the third business day preceding such Redemption Date, as set forth in the
daily statistical release (or any successor release) published by the Federal
Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for U.S.
Government Securities" or (2) if such release (or any successor release) is not
published or does not contain such prices on such business day, (A) the average
of the Reference Treasury Dealer Quotations (as hereinafter defined) for such
Redemption Date, after excluding the highest and lowest such Reference Treasury
Dealer Quotations, or (B) if the Trustee obtains fewer than four such Reference
Treasury Dealer Quotations, the average of all such Quotations.

                  "Independent Investment Banker" means J.P. Morgan Securities
Inc. or Salomon Smith Barney Inc.

                  "Reference Treasury Dealer" means J.P. Morgan Securities Inc.
or Salomon Smith Barney Inc. and their respective successors and, at the option
of the Company, other primary U.S. government securities dealers in New York
City selected by the Company.

                  "Reference Treasury Dealer Quotations" means, with respect to
the Reference Treasury Dealer and any Redemption Date, the average, as
determined by the Trustee, of the bid and asked prices for the Comparable
Treasury Issue (expressed in each case as a percentage of its principal amount)
quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m.,
New York City time, on the third business day preceding such Redemption Date.

                  "Remaining Scheduled Payments" means, with respect to any
Note, the remaining scheduled payments of the principal thereof to be redeemed
and interest thereon that would be due after the related Redemption Date but for
such redemption; provided, however, that, if such Redemption Date is not an
Interest Payment Date with respect to such Note, the amount of the next
succeeding scheduled interest payment thereon will be reduced by the amount of
interest accrued thereon to such Redemption Date.

                  "Treasury Rate" means, with respect to any Redemption Date for
the Notes, the rate per annum equal to the semi-annual equivalent yield to
maturity of the Comparable Treasury Issue, calculated using a price for the
Comparable Treasury Issue (expressed as a percentage of its principal amount)
equal to the Comparable Treasury Price for such Redemption Date.

                  Notice of any redemption by the Company will be mailed at
least 30 days but not more than 60 days before any Redemption Date to each
Holder of Notes to be redeemed. If less

                                       5
<PAGE>

than all the Notes are to be redeemed at the option of the Company, the Trustee
shall select the Notes to be redeemed in whole or in part by random lot.

                  This Note is not subject to a sinking fund. Holders of Notes
will not be permitted to require the Company to redeem or repurchase the Notes
at their option.

                  In case an Event of Default shall have occurred and be
continuing with respect to the Notes, the principal hereof may be declared, and
upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture. The Indenture
provides that in certain events such declaration and its consequences may be
waived by the Holders of a majority in aggregate principal amount of the Notes
then outstanding. An Event of Default with respect to the Senior Debt Security
of any other Series issued under the Indenture, including the failure to make
any payment of principal or interest with respect thereto when and as due, will
not necessarily be an Event of Default with respect to the Notes.

                  The Indenture, as supplemented by the Indenture Supplement
relating to the Notes, 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 Notes, or reduce the
principal amount thereof, or reduce the rate or extend the time of payment of
interest thereon, or reduce any premium payable on the redemption thereof,
without the consent of the Holder of each Note so affected, or (ii) reduce the
aforesaid percentage of Notes, the consent of the Holders of which is required
for any such supplemental indenture, without the consent of the Holders of all
Notes then outstanding. The Indenture also provides that the Holders of a
majority in aggregate principal amount of the Notes at the time outstanding may
on behalf of the Holders of all the Notes waive any past default under the
Indenture and its consequences, except a default in the payment of the principal
of or premium, if any, or interest on any of the Notes. 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 of any Note issued in exchange or substitution herefor,
whether or not any notation of such consent or waiver is made upon this Note.

                  As set forth in, and subject to, the provisions of the
Indenture, no Holder of any Note will have any right to institute any proceeding
with respect to the Indenture or for any remedy thereunder, unless such Holder
shall have previously given to the Trustee written notice of default in respect
of the Notes and of the continuance thereof, and unless 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 or
proceedings in its own name as Trustee hereunder and shall have furnished to the
Trustee such reasonable indemnity as it may require, and the Trustee shall have
failed to institute such proceeding within 60 calendar days; provided, however,
that such limitations do not apply to a suit instituted by the Holder hereof for

                                       6

the enforcement of payment of the principal of and any premium or interest on

transfer at the office or agency maintained by the Company for such purpose,
duly endorsed by, or accompanied by a written instrument of transfer in form

transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

                  The Company, the Trustee, any paying agent and any Senior Debt
Security Registrar for the Notes may deem and treat the 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 such Senior Debt Security Registrar), for the
purpose of receiving payment hereof or on account hereof and for all other
purposes, and neither the Company nor the Trustee nor any paying agent nor any
such Senior Debt Security Registrar shall be affected by any notice to the
contrary.

                  No recourse shall be had for the payment of the principal of,
or premium, if any, or interest on, this Note, or for any claim based hereon or
otherwise in respect hereof, or based on or in respect of the Indenture or any
indenture supplemental thereto, against any incorporator, stockholder, officer
or director, as such, past, present or future, of the Company or of 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.

3.       TERM.

         The initial term of this Agreement shall be from March 1, 2001 until
February 28, 2003 unless sooner terminated in accordance with the provisions
herein regarding termination. Subject to earlier termination as provided herein,
the initial term of this Agreement shall be automatically extended for one (1)
year from March 1, 2003, unless either the Employee or the Company gives written
notice to the other six months or more prior to February 28, 2003.

4.       COMPENSATION.

         (a) Base Salary. For all services rendered by the Employee under this
Agreement, the Company shall pay the Employee a base salary of $350,000 per
year. Such salary shall be payable in equal monthly installments in accordance
with the customary payroll policies of the Company in effect at the time such
payment is made, or as otherwise mutually agreed upon. Effective as of March 1
of each year during the term hereof, the Compensation Committee of the Company
shall review Employee's performance for the prior fiscal year and make such
adjustments in base salary from time to time at their discretion as the Employee
and the Company may agree.

         (b) Annual Bonus. Effective for the Company's fiscal year ending
February 28, 2002 and continuing with respect to each subsequent fiscal year
thereafter during the term of this Agreement, the Company will pay Employee an
annual bonus equal to the sum of (a) the mathematical product of Employee's base
salary pursuant to Subsection 4(a) for such fiscal year multiplied by the
Applicable Revenue Bonus Percentage and (b) the mathematical product of the
Employee's base salary pursuant to Subsection 4(a) for such fiscal year
multiplied by the Applicable EPS Bonus Percentage. Employee's bonus pursuant to
this Subsection 4(b) shall be earned as of the end of the Company's fiscal year
and payable within five days after the Company's receipt of its audited annual
financial statements. The formula set forth herein for determining annual
bonuses shall be adjusted from time to time when and if there occur stock splits
or other changes in capital structure which result in an increase or decrease in
outstanding capital stock of more than 25%.

         (c) Bonus. In addition to the Employee's annual base salary and other
benefits provided for in this Agreement, the Company may pay to the Employee on
an annual basis a discretionary bonus in an amount to be approved by the Board
of Directors of the Company; provided, however, in no event shall the bonus
payable hereunder, if any, exceed Employee's annual base salary provided for in
Section 4(a).

         (d) Benefits. The Employee shall be entitled to participate in or
receive benefits under any employee benefit plan or arrangement made available
by the Company in the future to its executive officers and key management
personnel, subject to and on a basis consistent with the terms, conditions and
overall administration of such plan or arrangement. Nothing paid to the Employee
under any plan or arrangement presently in effect or made available in the
future shall be deemed to be in lieu of the salary and bonuses payable to the
Employee pursuant to Subsections 4(a), (b) and (c).

         (e) Stock Option. In consideration of the Employee's execution of the
Old Agreement, the Company granted effective June 26, 2000 options to purchase
an aggregate of 500,000 shares of the Company's Common Stock to the Employee
pursuant to the Company's 1990 Incentive Stock Option Plan and 1999 Stock Option
Plan. The exercise price for such options was based on the price

2000, June 26, 2001, December 26, 2001, and June 26, 2002. The options are

the 1990 Incentive Stock Option Plan and nonqualified stock options to purchase

5.       POSITION, DUTIES, EXTENT OF SERVICES AND SITUS.

         (a) Position and Duties. Employee shall serve as the Chairman of the
Board, Chief Executive Officer and President of the Company, accountable only to
the Board of Directors of the Company and, subject to the authority of such
board, shall have supervision and control over, and responsibility for, the
general management and operation of the Company and shall have such other powers
and duties as may from time to time be prescribed by such board, provided that
such duties are reasonable and customary for a chairman of the board, chief
executive officer and president of a public company.

         (b) Extent of Services and Situs. The Employee shall devote
substantially all of his business time, attention, and energy to the business
and affairs of the Company and shall not during the term of his employment under
this Agreement engage in any other business activity which could constitute a
conflict of interest, whether or not such business activity is pursued for gain,
profit, or other pecuniary advantage. This shall not be construed as preventing
the Employee from managing his current investments or investing his assets in
such form or manner as will not require any services on the part of the Employee
in the operation and the affairs of the companies in which such investments are
made, subject to the provisions of Sections 6 and 27. The Employee shall not be
required to change the principal place of his employment to a location which is
more than 15 miles further away from his principal residence than such principal
place of employment at the time of the execution of this Agreement:

6.       COVENANT NOT TO COMPETE.

         (a) The Employee acknowledges that (i) as a result of his position and
tenure with the Company he has received and will continue to receive specialized
and unique training and knowledge concerning the Company, its business, its
customers and the industry in which it competes, (ii) the Company's business, in
large part, depends upon its exclusive possession and use of the Proprietary
Information (as defined in Section 27), (iii) the Company is entitled to
protection against the unauthorized disclosure or use by Employee of the
Proprietary Information or the training and knowledge received by the Employee
and (iv) he has received in this Agreement good and valuable consideration for
the covenants he is making in this Section 6 and in Section 27. The Company and
the Employee acknowledge and agree that the covenants contained in this Section
6 and in Section 27 are reasonably necessary for the protection of the Company
and are reasonably limited with respect to the activities they prohibit, their
duration, their geographical scope and their effects on the Employee and the
public. The parties acknowledge that the purpose and effect of the covenants are
to protect the Company from unfair competition by the Employee.

         (b) Except as provided in the last sentence of this Section 6(b),
during the period in which the Employee renders services to the Company under
this Agreement and for eighteen (18) months thereafter, the Employee shall not,
without the written consent of the Company, own, manage, operate, control, serve
as an officer, director, employee, partner or consultant of or be connected in
any way with or have any interest in any corporation, partnership,
proprietorship or other entity which carries on business activities in
competition with the Company's activities in any state of the United States or
in any foreign country in which the Company has sold or installed its products
or systems

                                       7
<PAGE>

or has definitive plans to sell or install its products at any time prior to or
at the time of the date of termination of the Employee's employment; except that
the Employee may own up to 1% of the shares of any publicly-owned corporation,
provided that none of his other relationships with such corporation violates
such covenant. Notwithstanding the foregoing, the provisions of this Section 6
shall not apply if the Employee's employment with the Company under this
Agreement is terminated (i) by the Company, unless the Employee is terminated in
accordance with Section 7 or for Cause in accordance with Subsection 9.1(a) or
9.2(a), or (ii) at the election of the Employee prior to the Triggering Date
after the occurrence of an Event of Default which has not been waived in writing
or on or after the Triggering Date for Good Reason.

         (c) The Company and the Employee hereby agree that in the event that
the noncompetition covenants contained herein should be held by any court or
other constituted legal authority of competent jurisdiction to be effective in
any particular area or jurisdiction only if said covenants are modified to limit
their duration, geographical area or scope, then the parties hereto will
consider Section 6 to be amended and modified with respect to that particular
area or jurisdiction so as to comply with the order of any such court or other
constituted legal authority and, as to all other jurisdictions or political
subdivisions thereof, the noncompetition covenants contained herein will remain
in full force and effect as originally written. The Company and the Employee
further agree that in the event that the noncompetition covenants contained
herein should be held by any court or other constituted legal authority of
competent jurisdiction to be void or otherwise unenforceable in any particular
area or jurisdiction notwithstanding the operation of this Section 6(c), then
the parties hereto will consider this Section 6 to be amended and modified so as
to eliminate therefrom that particular area or jurisdiction as to which such
noncompetition covenants are so held void or otherwise unenforceable, and, as to
all other areas and jurisdictions covered by the noncompetition covenants, the
terms and provisions hereof shall remain in full force and effect as originally
written.

         (d) Employee recognizes and acknowledges that the Company would suffer
irreparable harm and substantial loss if Employee violated any of the terms and
provisions of this Section 6 or Section 27 and that the actual damages which
might be sustained by the Company as the result of any breach of this Section 6
or Section 27 would be difficult to ascertain. Employee agrees, at the election
of the Company and in addition to, and not in lieu of, the Company's right to
terminate Employee's employment and to seek all other remedies and damages which
the Company may have at law and/or equity for such breach, that the Company
shall be entitled to an injunction restraining Employee from breaching any of
the terms or provisions of this Section 6 or Section 27.

7.       COMPENSATION IN THE EVENT OF DISABILITY.

         (a) Disability. If the Employee becomes disabled during the term of
this Agreement the Company shall cause to be paid to the Employee an amount
equal to his base salary in effect at the time of disability under Subsection
4(a), for the shorter of the duration of the disability or the remainder of the
term of this Agreement and, subject to the provisions of Sections 22 and 25,
with no liability on its part for further payments to the Employee during the
duration of the disability. Subject to Subsection 7(b) below, full compensation
shall be reinstituted upon his return to employment and resumption of his
duties. For purposes of this Subsection 7(a) the Employee shall be deemed
"disabled" when he is unable, for a period of 90 consecutive days, to perform
his normal duties of employment due to bodily injury or disease or any other
physical or mental disability.

                                       8
<PAGE>

         (b) Complete Disability. The Company shall have the right to terminate
the Employee's employment under this Agreement prior to the expiration of the
term upon the "Complete Disability" of the Employee as hereinafter defined
(provided, however, that the obligations of the Company under Subsection 7(a)
shall not terminate). The term "Complete Disability" as used in this Subsection
7(b) shall mean (i) the total inability of the Employee, due to bodily injury or
disease or any other physical or mental incapacity, to perform the services
provided for hereunder for a period of 120 days, in the aggregate, within any
given period of 180 consecutive days during the term of this Agreement, and (ii)
where such inability will, in the opinion of a qualified physician (reasonably
acceptable to Employee), be permanent and continuous during the remainder of his
life.

8.       COMPENSATION IN THE EVENT OF DEATH.

         If the Employee dies during the term of his employment, the Company
shall pay to such person as the Employee shall designate in a notice filed with
the Company, or, if no such person shall be designated, to his estate as a death
benefit, his base salary in effect at the time of his death pursuant to
Subsection 4(a), in equal semi-monthly installments on the first and fifteenth
day of each month immediately succeeding his death, for a period of months (not
exceeding 12) determined by multiplying the number of complete 12-month periods
of employment of the Employee by the Company (whether pursuant to an employment
agreement or not) by two, in addition to any payments the Employee's spouse,
beneficiaries, or estate may be entitled to receive pursuant to any pension or
employee benefit plan or life insurance policy maintained by the Company, and,
except for any obligations of the Company under Sections 22 and 25, all other
obligations of the Company hereunder shall cease at the time of the Employee's
death.

9.       TERMINATION.

         9.1 Termination Prior to the Triggering Date. (a) Upon at least 30
days' prior written notice to the Employee and prior to the Triggering Date, the
Company may terminate the Employee's employment with the Company under this
Agreement only for Cause or in accordance with Section 7 and, subject to the
provisions of Sections 7, 22 and 25, with no liability on its part for further
payments to the Employee. The Company may effect a termination for Cause
pursuant to this Subsection 9.1(a) only by the affirmative vote of a majority of
the members of the Board of Directors of the Company. In voting upon such
termination for Cause, if the Employee is also a member of the Board of
Directors of the Company, then he may not vote on, and will not be considered
present for any purpose with respect to, a matter presented to the Board of
Directors of the Company pursuant to this Subsection 9.1(a).

         (b) Prior to the Triggering Date, the Employee may terminate his
employment with the Company under this Agreement by giving at least 90 days'
prior written notice of his desire to terminate employment to the Board of
Directors of the Company. If the Employee's employment with the Company under
this Agreement is terminated pursuant to this Subsection 9.1(b), the Employee
will continue to accrue and receive his base salary in effect at the time
pursuant to Subsection 4(a) through the date of termination with no liability on
the part of the Company for further payments to the Employee, subject to the
provisions of Sections 22 and 25.

                                       9
<PAGE>

         (c) Prior to the Triggering Date, if the Employee's employment with the
Company is terminated by the Company without Cause or if the Employee terminates
his employment with the Company following the occurrence of an Event of Default
which has not been waived in writing by the Employee, the Employee will continue
to accrue and receive his base salary in effect at the time pursuant to
Subsection 4(a) through the date of termination and will be entitled to receive
the benefits provided for under Subsection 10.1 (unless the Employee's
employment is terminated in accordance with Section 7) with no liability on the
part of the Company for further payments to the Employee, subject to the
provisions of Sections 7, 22 and 25.

         9.2 Termination On or After the Triggering Date. (a) Upon at least 30
days' prior written notice to the Employee and on or after the Triggering Date,
the Company may terminate the Employee's employment with the Company under this
Agreement only for Cause or in accordance with Section 7 and, subject to the
provisions of Sections 7, 22 and 25, with no liability on its part for further
payments to the Employee. The Company may effect a termination for Cause
pursuant to this Subsection 9.2(a) only by the affirmative vote of two-thirds of
the members of the Board of Directors of the Company. In voting upon such
termination for Cause, if the Employee is also a member of the Board of
Directors of the Company, then he may not vote on, and will not be considered
present for any purpose with respect to, a matter presented to the Board of
Directors of the Company pursuant to this Subsection 9.2(a).

         (b) On or after the Triggering Date, if the Employee's employment with
the Company is terminated by the Company without Cause or if the Employee
terminates his employment with the Company for Good Reason, the Employee will
continue to accrue and receive his base salary in effect at the time pursuant to
Subsection 4(a) through the date of termination and will be entitled to receive
the payments and benefits provided for under Subsections 10.2 and 10.3 (unless
the Employee's employment is terminated in accordance with Section 7) with no
liability on the part of the Company for further payments to the Employee,
subject to the provisions of Sections 7, 22 and 25.

         (c) On or after the Triggering Date, the Employee may, in his sole and
absolute discretion and without any prior approval by the Board of Directors of
the Company, and upon twelve months' prior written notice to the Board of
Directors of the Company, terminate his employment with the Company under this
Agreement for any reason whatsoever. If the Employee's employment with the
Company under this Agreement is terminated pursuant to this Subsection 9.2(c),
the Employee will continue to accrue and receive his base salary in effect at
the time pursuant to Subsection 4(a) through the date of termination and will be
entitled to receive the benefits provided for under Subsections 10.2 and 10.3

10.      COMPENSATION AFTER CERTAIN TERMINATIONS.

         10.1 Remaining Compensation. If the Employee's employment with the
Company is terminated (whether such termination is by the Employee or by the
Company) at any time prior to the Triggering Date for any reason other than (a)
termination by the Company for Cause in accordance with Subsection 9.1(a); (b)
termination by the Company in accordance with Section 7; (c) the Employee's
death; or (d) termination at the election of the Employee pursuant to Subsection
9.1(b) then, within five days after the date of such termination, (i) the
Remaining Compensation (as herein defined) which would have been paid to the
Employee during the remainder of the term of this Agreement if termination had
not occurred shall become due and payable and shall be paid to the Employee in a
single lump sum in cash, and (ii) all stock options granted to Employee pursuant
to Subsection 4(e) hereof which are not then exercisable shall, notwithstanding
the provisions of any other agreement, become immediately exercisable and shall
remain exercisable until they are exercised or until they otherwise would
expire. For purposes of this Subsection 10.1, the "Remaining Compensation" shall
mean the annual base salary payable to the Employee pursuant to Subsection 4 (a)
at the time of termination plus an amount representing the value of all employee
benefits including, without limitation, any unearned annual bonuses described in
Subsection 4 (b), discretionary bonuses and incentive compensation under plans
then in effect. For these purposes, the value of any unearned annual bonuses and
all of such other employee benefits shall be deemed to be equal to 12 months
base salary payable to the Employee pursuant to Subsection 4(a) at the time his
employment is terminated.

         10.2 Post Triggering Date Severance Payment. If the Employee's
employment with the Company is terminated (whether such termination is by the
Employee or by the Company) at any time on or within three years after the
Triggering Date for any reason other than (a) termination by the Company for
Cause in accordance with Subsection 9.2(a) or (b) termination by the Company in
accordance with Section 7 or (c) the Employee's death or (d) termination at the
election of the Employee other than termination for Good Reason without
compliance with the retirements of Section 9.2(c), then, within five days after
the date of such termination, the Company shall pay the Employee a lump sum
amount in cash equal to 2.99 times the Annualized Compensation Amount.

         10.3 Gross-Up Payment. In the event that (i) the Employee becomes
entitled to the payments provided under Section 10.2 of this Agreement (the
"Change in Control Payments") and any of the Change in Control Payments will be
subject to the tax (the "Excise Tax") imposed by Section 4999 of the Internal
Revenue Code of 1986, as amended (the "Code"), or any successor provision, or
(ii) any payments or benefits received or to be received by the Employee
pursuant to the terms of any other plan, arrangement or agreement (the "Benefit
Payments") will be subject to the Excise Tax, the Company shall pay to the
Employee an additional amount (the "Gross-Up Payment") such that the net amount
retained by the Employee, after deduction of any Excise Tax on the Change in
Control Payments and the Benefit Payments, and any federal, state and local
income tax and Excise Tax upon the payment provided for by this Section 10.3,
shall be equal to the Change in Control Payments and the Benefit Payments,
provided, however, that in determining the amount of the Gross-Up Payment, any
Excise Tax on the Change in Control Payments and the Benefit Payments shall be
determined using a rate no higher than 20%. For purposes of determining whether
any of the Change in Control Payments or the Benefit Payments will be subject to
the Excise Tax and the amount of such Excise Tax, (i) any payments or benefits
received or to be received by the

                                       11
<PAGE>

Employee in connection with a change in control of the Company or the Employee's
termination of employment (whether pursuant to the terms of this agreement or
any other plan, arrangement or agreement with the Company, any person whose
actions result in change in control or any person affiliated with the Company or
such persons) shall be treated as "parachute payments" within the meaning of
Section 280G(b) (2) of the Code, and all "excess parachute payments" within the
meaning of Section 280G(b) (1) shall be treated as subject to the Excise Tax,
unless in the opinion of tax counsel selected by the Company's independent
auditors and acceptable to the Employee such payments or benefits (in whole or
in part) do not constitute parachute payments, or such excess payments (in whole
or in part) represent reasonable compensation for services actually rendered
within the meaning of Section 280G(b) (4) of the Code, (ii) the amount of the
Change in Control Payments and the Benefit Payments that shall be treated as
subject to the Excise Tax shall be equal to the lesser of (A) the total amount
of the Change in Control Payments and the Benefit Payments or (B) the amount of
excess parachute payments within the meaning of Sections 280G(b)(1) and (4)
(after applying clause (i), above) and (iii) the value of any non-cash benefits
or any deferred payment or benefit shall be determined by the Company's
independent auditors in accordance with the principles of Sections 280G(d)(3)
and (4) of the Code. For purposes of determining the amount of the Gross-Up
Payment, the Employee shall be deemed to pay federal income taxes at the highest
marginal rate of federal income taxation in the calendar year in which the
Gross-Up Payment is to be made and state and local income taxes at the highest
marginal rates of taxation in the state and locality of the Employee's residence
on the date of termination, net of the maximum reduction in federal income taxes
which could be obtained from deduction of such state and local taxes. In the
event that the Excise Tax is subsequently determined to be less than the amount
taken into account hereunder at the time of termination of the Employee's
employment, the Employee shall repay to the Company at that time that the amount
of such reduction in Excise Tax is finally determined the portion of the
Gross-Up Payment attributable to such reduction plus interest on the amount of
such repayment at the rate provided in Section 1274(b)(2)(B) of the Code. In the
event that the Excise Tax is determined to exceed the amount taken into account
hereunder at the time of the termination of the Employee's employment (including
by reason of any payment the existence or amount of which cannot be determined
at the time of the Gross-Up Payment), the Company shall make an additional
gross-up payment to the Employee in respect of such excess (plus any interest
payable with respect to such excess) at the time that the amount of such excess
is finally determined.

11.      MITIGATION.

         The Employee shall not be required to mitigate the amount of any
payment provided for in this Agreement by seeking other employment or otherwise,
nor shall the amount of any payment provided for in this Agreement be reduced by
any compensation earned by the Employee as the result of employment by another
employer after the date of termination of Employee's employment with the
Company, or otherwise.

12.      ENTIRE AGREEMENT.

         This Agreement embodies the entire agreement and understanding between

Company shall be permitted to assign this Agreement to any corporation or other
business entity succeeding to substantially all of the business and assets of
the Company by merger, consolidation, sale of assets, or otherwise, if the
Company obtains the assumption of this Agreement by such successor. Failure by
the Company to obtain such assumption prior to the effectiveness of such
succession shall be a breach of this Agreement and shall entitle the Employee to
receive compensation from the Company under this Agreement in the same amount

terminated his employment after the Triggering Date, and, for purposes of
implementing the foregoing, the date on which any such succession becomes

together constitute one and the same instrument. The terms of this Agreement
shall become binding upon each party from and after the time that he or it
executed a copy hereof. In like manner, from and after the time that any party
executes a consent or other document, such consent or other document shall be
binding upon such parties.

24.      WITHHOLDING OF TAXES.

27.      ASSIGNMENT, PROTECTION AND CONFIDENTIALITY OF PROPRIETARY INFORMATION.

Employee acknowledges and agrees that all items of the Company's Proprietary
Information constitute valuable, special and unique assets and trade secrets of
its business, which provide to the Company a competitive advantage over others
who do not have access thereto and access to which is essential to the
performance of Employee's duties hereunder. Employee shall not, during the term
of this Agreement or thereafter, use or disclose any Proprietary Information
that is not otherwise publicly available, in whole or in part, for his benefit
or for the benefit of any other person or party, except for the Company. As used
herein, "Proprietary Information" includes, but is not limited to, customer
lists and prices, whether current or prospective, product designs or other
product information, experimental developments and other research and
development information, testing processes, marketing studies and research
activities, and any other trade secrets concerning the Company, its
shareholders, officers, directors, employees, business prospects, customers,
transactions, finances, affairs, opportunities, operations, properties or
assets. The Employee further agrees that all inventions, devices, compounds,
processes, formulas, techniques, improvements and modifications which he may
develop, in whole or in part, during the term of his employment or through or
with the facilities, equipment or resources of the Company shall be and remain
the sole and exclusive property of the Company. The Employee agrees to deliver
to the Company at any time the Company may request, all memoranda, notes, plans,
records, reports, and other documents (including copies thereof and all
embodiments thereof whether in computerized form or any other medium) relating
to the business or affairs of the Company or its subsidiaries which he may then
possess or have under his control. Employee shall maintain in good condition all
tangible and other forms of Proprietary Information in Employee's custody or
control until his obligations under the preceding sentence are satisfied.
Employee agrees to execute all documents and take such other actions as may be
required to comply with this Section.
