                                PROXY STATEMENT

                        Annual Meeting of Shareholders
                           to be held April 19, 1999

      This Proxy Statement is being furnished to the common shareholders of
Cass Commercial Corporation (the "Company") on or about March 22, 1999 in
connection with the solicitation of proxies on behalf of the Board of
Directors of the Company for use at the annual meeting of shareholders (the
"Annual Meeting") to be held on April 19, 1999 at the time and place and for
the purposes set forth in the accompanying Notice of Annual Meeting, and at
any adjournment or postponement of that meeting.

      Holders of shares of common stock, par value $.50 per share ("Shares"
or the "Common Stock"), of the Company at its close of business on March 5,
1999, (the "Record Date") are entitled to receive notice of and vote at the
Annual Meeting.  On the Record Date, 3,873,711 shares of Common Stock were
outstanding.  Holders of Common Stock (the "Shareholders") are entitled to
one vote per share of Common Stock they held of record on the Record Date on
each matter that may properly come before the Annual Meeting.

      A plurality of the votes of Shareholders cast at the Annual Meeting is
required for the election of each director.  Ratification of the selection of
independent accountants requires the affirmative vote of holders of a
majority of the shares of Common Stock voted.  The proposed amendment to the
1995 Performance-Based Stock Option Plan requires the affirmative vote of
shareholders holding a majority of the shares of Common Stock voted at the
meeting.  Abstentions and broker non-votes are counted in the number of
shares present in person or represented by proxy for purposes of determining
whether a quorum is present, but not for purposes of election of directors,
ratification of the selection of independent accountants or approval of the
proposed amendments to the 1995 Performance-Based Stock Option Plan.

      Management of the Company ("Management"), together with members of the
Board of Directors of the Company, in the aggregate, directly or indirectly
controlled approximately 21.5% of the Common Stock outstanding on the Record
Date.

      Shareholders of record on the Record Date are entitled to cast their
votes in person or by properly executed proxy at the Annual Meeting.  The
presence, in person or by properly executed proxy, of a majority of the
Common Stock outstanding on the Record Date is necessary to constitute a
quorum at the Annual Meeting.  If a quorum is not present at the time the
Annual Meeting is convened the Company may adjourn or postpone the Annual
Meeting.

      All Common Stock represented at the Annual Meeting by properly executed
proxies received prior to or at the Annual Meeting and not properly revoked
will be voted at the Annual Meeting in accordance with the instructions
indicated in such proxies.  If no instructions are indicated, such proxies
will be voted FOR the election of the Board's director nominees, FOR the
              ---                                                ---
ratification of the selection of independent accountants and FOR the approval
                                                             ---
of amendments to the 1995 Performance-Based Stock Option Plan.  The Board of
Directors of the Company does not know of any matters, other than the matters
described in the Notice of Annual Meeting attached to this Proxy Statement,
that will come before the Annual Meeting.

      Any proxy given pursuant to this solicitation may be revoked by the
person giving it at any time before it is voted.  Proxies may be revoked by
(i) filing with the Secretary of the Company, at or before the Annual
Meeting, a written notice of revocation bearing a date later than the date of
the proxy, (ii) duly executing and dating a subsequent proxy relating to the
Common Stock and delivering it to the Secretary of the Company at or before
the Annual Meeting, or (iii) attending the Annual Meeting and voting in
person (although attendance at the Annual Meeting will not in and of itself
constitute a revocation of a proxy). Any written notice revoking a proxy
should be sent to:  Corporate Secretary, Cass Commercial Corporation, 13001
Hollenberg Drive, Bridgeton, Missouri 63044 (telephone number (314)
506-5500).

      The proxies are solicited by the Board of Directors of the Company.  In
addition to the use of the mails, proxies may be solicited personally or by
telephone or facsimile transmission, by directors, officers or regular
employees of the Company or persons employed by the Company for the purpose
of soliciting proxies.  It is contemplated that brokerage houses, custodians,
nominees and fiduciaries will be requested to forward the soliciting material
to the beneficial owners of Common Stock held of record by such persons, and
will be reimbursed by the Company for expenses incurred therewith.  The cost
of solicitation of proxies will be borne by the Company.

      The Company has two wholly-owned subsidiaries; Cass Commercial Bank
("Cass Bank") and Cass Information Systems, Inc. ("CIS").

             The date of this Proxy Statement is March 22, 1999.

STOCK OPTION PLAN / STOCK BONUS PLAN

      During May 1995, the Company's Board of Directors established the 1995
Performance-Based Stock Option Plan (the Option Plan) and the 1995 Restricted
Stock Bonus Plan (the Bonus Plan).  These plans were adopted to aid the
Company in securing and retaining qualified personnel.

      The Option Plan provides for the granting of options on up to 400,000
shares of the Company's common stock.  As of December 31, 1998, 95,400, 6,000
and 8,500 options were outstanding at exercise prices of $10.32, $20.36 and
$25.45, respectively.  Of these shares 25,960 were exercisable with a
weighted average exercise price of $10.32.  These options vest over a period
not to exceed seven years, but the vesting period can be accelerated based on
the Company's attainment of certain financial operating performance criteria.
Shareholders are asked to vote on amendments to the Option Plan at the Annual
Meeting.

      The Bonus Plan provides for the issuance of up to 100,000 shares of the
Company's common stock.  As of December 31, 1998, an aggregate of 35,000
shares of the Company's common stock had been awarded to six participants.
Interest in the shares of common stock awarded under the Bonus Plan vest over
a three year period.  Common stock awarded under the Bonus Plan is accounted
for through the establishment of a contra shareholders' equity account.  This
contra shareholders' equity account is amortized against income over the
vesting period of the stock awards.

                             OPTION GRANTS IN 1998

      There were no options granted to any of the above named executive
officers in 1998.

DEFINED BENEFIT RETIREMENT PLANS


RETIREMENT PLAN FOR EMPLOYEES OF CASS COMMERCIAL CORPORATION

      All officers of the Company and subsidiaries are participants in the
Retirement Plan for Employees of Cass Commercial Corporation, which covers
all full-time employees.  Upon retirement, participants in the plan will
begin to receive monthly payments equal to one-twelfth of the sum of:

      (a)   .9% of Final Average Earnings multiplied by the number
            of years of participation, plus

      (b)   .5% of Final Average Earnings in excess of Covered
            Compensation multiplied by years of participation.

      Final Average Earnings is defined as the average annual total
compensation for the five consecutive years of highest earnings during the
last ten years of employment.  Covered Compensation is the average of the
maximum social security taxable wage bases in effect for each calendar year
during the 35-year period ending with the year in which retirement age is
attained under the Social Security Act.  Earnings covered by the Plan equal
total compensation as reported in the Summary Compensation Table including
any amounts deferred under the Cass Commercial Corporation 401(k) Plan plus
any noncash compensation reported on Internal Revenue Service Form W-2.

      Normal retirement under the Plan commences at age 65.  At normal
retirement the years of participation under the Plan for the executive
officers listed in the Compensation Table would be as follows: Mr.
Collett-41; Mr. Brunngraber-41; Mr. Bouchein-13.

      The following table shows the estimated annual benefits payable at
retirement, assuming a straight-life annuity with 120 months guaranteed.

<F1>  Estimated benefit calculation assumes retirement at age 65 in the year
      2000 with no increase in the maximum social security taxable wage base
      after 1998.

<F2>  Estimated benefits would be subject to Internal Revenue Service maximum
      retirement limitations in effect at the retirement date.  The maximum
      compensation that may be recognized for determining benefits in 1998 is
      $160,000.


SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

      In addition to the above defined benefit plan, in 1998 the Company
established the Cass Commercial Corporation Supplemental Retirement Plan,
which covers key executive officers of the Company.  This supplemental plan
was designed to provide additional retirement benefits to key executives
whose benefits are limited by the Internal Revenue Service under the
Company's qualified plan.

                                    -8-

      Upon retirement, participants in the plan will receive monthly payments
equal to one twelfth of 70% of Final Average Earnings and reduced
proportionately for length of service less than 25 years and
reduced by the participant's:

      (a)   Qualified retirement plan benefit,

      (b)   Primary social security benefit, and

      (c)   401(k) hypothetical annuity

      Final Average Earnings, normal retirement age and years of
participation at normal retirement of Mr. Collett, Mr. Brunngraber and Mr.
Bouchein are the same as under the Retirement Plan for Employees of Cass
Commercial Corporation.

DEFINED CONTRIBUTION SAVINGS PLAN

      All full-time employees of the Company and subsidiaries are eligible to
participate in the Cass Commercial Corporation 401(k) Plan.  Employees may
voluntarily defer up to 15% of pre-tax earnings subject to the IRS maximum
limitation which was $10,000 for 1998.  Voluntary deferrals contributed to
the 401(k) Plan by the Executive Officers are included in Annual Salary
Compensation in the Summary Compensation Table.  The Company matches 50% of
the first 3% of employee contributions, subject to IRS limitations.  Amounts
contributed to the Plan in 1998, for the benefit of the Executive Officers,
are included in Other Compensation in the Summary Compensation Table.  Each
Executive Officer is fully vested in Company contributions.

BOARD COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

      The Compensation Committee of the Board of Directors (the "Committee")
is composed of three independent directors, one of which serves as chairman
of the Committee.  The Committee administers the Executive Compensation
Program of the Company and none of the members have been or are an employee
of the Company or of any of its subsidiaries.  All material items relative to
Executive Compensation or any benefit compensation for the entire Company
must be analyzed, reviewed and approved by the Compensation Committee.  While
the Committee may seek input occasionally from the Chief Executive Officer,
the Chief Financial Officer or the Director of Human Resources, all matters
are independently resolved and decided without the presence or voting of any
officer of the Company or its subsidiaries. The Compensation Committee of the
Board is also responsible for recommending salary levels for executive
officers to the Board of Directors of the Company and recommending the
overall levels of salary compensation for the entire corporation.

      The Committee's philosophy with regard to executive compensation has
been to seek to provide programs which will allow the Company to acquire and
maintain competent executive officers and to attract and maintain other
management personnel with the capabilities and requirements determined
necessary to continue to lead the Company in meeting its objectives and in
furthering its growth and profitability. It is further the philosophy of the
Committee to constantly upgrade the caliber of performance of the Company's
staff and reward its people in accordance with the results that are
accomplished. The Committee believes that total compensation should be
related to profits and to the performance of the Company.  For this reason, a
significant component of the compensation of the Company's executives is tied
to an incentive bonus plan that is directly related to the Company's pre-tax
earnings.  Most of the executives received increases in 1998 bonuses due to
the improved level of profits achieved.

      The Committee generally seeks to maintain salaries at the mid-point
levels of competitive peer groups.  Bonuses are available to all personnel in
the Company based upon the level of profits before taxes achieved by the
Company.  These bonuses are distributed on the basis of merit.  Performance
is measured on the basis of several factors deemed relevant to performance
and bonuses are distributed on the basis of these evaluations.  The
determination of bonuses for the Company's executive officers is a subjective
process which utilizes no specific performance criteria, but which does
consider growth in the Company's profits, resources, and the quality of the
Company's operations, as well as adherence to regulatory requirements.

      The Committee utilizes the services of Peter R. Johnson & Company of
West Chester, Pennsylvania in determining the levels of peer compensation
within its industry.  Additionally, the Committee utilizes the services of
Towers Perrin for evaluation of the compensation of its three top executive
positions.  The Committee considers stock options and grants to be a
significant motivational tool for rewarding its executive officers and senior
management.  Stock awards provided under the Company's stock option plan are
granted primarily on the basis of performance of the Company, performance of
the individual operating subsidiaries, the relationship of the Company's
performance to other companies in its peer group, and the recommendation of
the CEO.  No new stock incentive programs were provided in 1998.  The company
utilizes the services of Towers Perrin in determining appropriate stock
incentive and compensation and annually reviews information from other
compensation sources for other bank holding companies and companies
performing in industries similar to those of its operating subsidiaries.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      Some of the directors and officers of the Company and of the Bank, and
members of their immediate families and firms and corporations with which
they are associated, have had transactions with the Bank, including borrowing
and investments in depository accounts.  All such loans and investments have
been made in the ordinary course of business, have been made on substantially
the same terms, including interest rates paid or charged and collateral
required, as those prevailing at the same time for comparable transactions
with unaffiliated persons, and did not involve more than the normal risk of
collectibility or present other unfavorable features.  As of December 31,
1998, the aggregate amount of all loans and available credit to officers and
directors of the Company and to firms and corporations in which they have at
least a 10% beneficial interest was approximately $3.4 million, which
represented approximately 5.9% of the Company's consolidated shareholders'
equity at that date.

      Bruce E. Woodruff, a director and shareholder of the Company, is of
counsel to the law firm of Armstrong Teasdale LLP, counsel to the Company and
subsidiaries.

SECTION 16(a) BENEFICIAL OWNERSHIP COMPLIANCE

      To the Company's knowledge, based solely on review of copies of such
reports furnished to the Company and written representations that no other
reports were required, during 1998 all Section 16(a) filing requirements were
complied with by all persons who, during the year, were directors, officers
or holders of 10% or more of the Company's shares.


                       AMENDMENTS TO THE COMPANY'S 1995
                      PERFORMANCE-BASED STOCK OPTION PLAN

      Subject to shareholder approval, the Company's Board of Directors
amended the Cass Commercial Corporation 1995 Performance-Based Stock Option
Plan effective January 19, 1999, to permit the granting of incentive stock
options under the Option Plan in addition to the non-qualified stock options
previously provided under the Option Plan.

      The purposes of the Option Plan are to aid the Company and its
subsidiaries, Cass Commercial Bank and Cass Information Systems, Inc. in
securing and retaining qualified personnel by making it possible to offer
them an increased incentive, in the form of a proprietary interest in the
Company, to join or continue in the service of the Company or its
subsidiaries and increase their efforts for its welfare.  The Board of
Directors believes stock options have played a critical role in recent years
in motivating Company management to build a growing, highly competitive
business, while also delivering a consistently strong financial performance
record with corresponding stock appreciation.

      The Option Plan was originally approved by the Company's shareholders
on April 22, 1996.  As originally adopted, the Option Plan permitted the
granting of only non-qualified stock options.  A holder of a non-qualified
stock option who exercises the option recognizes ordinary income at the time
of exercise, in an amount equal to the fair value of the shares at the time
of exercise less the exercise price, and the Company receives a corresponding
tax deduction.  Therefore, to exercise a non-qualified option, the holder
must not only pay the exercise price of the shares but a significant amount
of income tax.  The tax cost to an employee who exercises a non-qualified
stock option significantly reduces the benefit of the option to the employee.

      The amendments permit the Compensation Committee to grant incentive
stock options under the Option Plan as an alternative to non-qualified stock
options.  An optionee does not realize any income upon the exercise of an
incentive stock option, nor does the company receive any deduction.  If the
stock is not sold or gifted for at least two years after the option grant and
at least one year after the exercise, no ordinary income is realized with
respect to the disposition.  The Optionee's tax basis in the shares is the
exercise price, and any gain or loss to the Optionee is a capital gain or
loss.  However, if the stock is disposed of before then, the tax effects of
the exercise and sale are similar to what they would be if the option had
been a non-qualified option.

      Because of the favorable tax treatment to the optionee, the Board of
Directors believes that being able to grant incentive stock options as an
alternative to non-qualified stock options gives the Compensation Committee
more flexibility in offering options as incentives, and also believes that
the increased incentive to the Company's employees outweighs the loss of tax
benefits to the Company.

      The amendments also permit directors of the Company, as well as
employees, to be granted non-qualified stock options under the Option Plan.
Previously, directors who were not also employees of the Company were not
eligible to participate in the Option Plan.  By law, directors who are not
employees are not eligible to receive incentive stock options.  The Board
believes that permitting directors to receive options under the Option Plan
will tend to align their interests more closely with the interests of the
shareholders and provide an additional incentive for Board members.

      The full text of the Option Plan as amended is attached to this Proxy
Statement as Exhibit I.

      MANAGEMENT OF THE COMPANY RECOMMENDS VOTING FOR APPROVAL OF THE
AMENDMENTS TO THE OPTION PLAN.

Shares only (i) on or after the Vesting Date with respect to such Option

       5.4     Possibility of Accelerated Vesting.  The Vesting Date with
respect to all Option Shares shall be subject to acceleration as follows:
               (i)     Each Option shall be eligible to be considered for
       accelerated vesting beginning with the annual determinations of NI
       Growth and ROA Differential made in the second calendar year after the
       Option is granted, so that the earliest possible Vesting Date for any
       Option Shares shall be the first Business Day in January of the third
       year after it is granted.
               (ii)    As early in each calendar year as the necessary
       information is available, the Compensation Committee shall calculate
       NI Growth and ROA Differential for each entity required, calculating
       the percentages in each case to two decimal places (i.e. 1/100 of 1%).
               (iii)   Using the applicable Performance Matrix, the Compensation
       Committee shall then determine, for each Option eligible for
       accelerated vesting, the percentage (if any) of Option Shares which
       shall be subject to an accelerated Vesting Date, calculating such
       percentage to one decimal place (i.e. 1/10 of 1%).  The applicable
       Performance Matrix shall be the Performance Matrix for the Optionee's
       employer, except that (A) in the case of Options granted to employees
       of CIS, the CCC Performance Matrix and the CIS Performance Matrix
       shall both be used, and the two resulting percentages shall be
       averaged, and (B) in the case of Options granted to employees of Cass
       Bank, the CCC Performance Matrix and the Cass Bank Performance Matrix
       shall both be used, and the two resulting percentages shall be
       averaged.  No more than 30% of the Option Shares shall be subject to
       accelerated vesting in any year.
               (iv)    The percentages so obtained shall be multiplied by the
       total original number of Option Shares, and the Vesting Date for the
       resulting number of Option Shares shall be accelerated from the
       original Vesting Date to the first Business Day in January of the
       calendar year following the year in which the determination was made.
               (v)     The Compensation Committee shall promptly notify each
       Optionee of the percentage and number of Option Shares as to which the
       Vesting Date shall have been accelerated, and the resulting Vesting
       Date for such Option Shares.
               (Example of timing:  With respect to Options granted in 1995,
                -----------------
               the first calculations shall be made in 1997, with NI Growth
               calculated on net income growth from 1993 to 1996 and ROA
               Differential calculated over the years 1994 through 1996; the
               Vesting Date for the resulting number of Option Shares shall be
               accelerated from January 2, 2002 to January 2, 1998.)
       5.5     Automatic Acceleration of Vesting in the Event of a Change in
Control.  The Vesting Date shall be automatically accelerated, and all
Options then outstanding under this Plan shall become immediately exercisable
in full upon the first to occur of (i) a Change in Control, or (ii) the
approval by the Board of a Change in Control, or (iii) 10 days before the
record date, if any, for determining the shareholders of the Company eligible
to vote on a proposed Change in Control, or (iv) 10 days before the last date
for determining the shareholders of the Company eligible to participate in
any Change in Control in which the Company's common stock would be sold,
exchanged or converted for or into cash, property or other securities;
provided that if (A) the Company remains in existence and continues to carry
on its business following the Change in Control, and (B) the Common Stock
continues to be listed for trading with the Nasdaq Stock Market after the
Change in Control, and (C) after the Change in Control, no person or group of
persons acting in concert possesses more than a majority of the voting power
for the election of directors of the Company, then such acceleration of the
Vesting Date shall occur only if and to the extent that acceleration of the
Vesting Date is provided for in an individual Option Agreement.  A Change in
Control shall not extend the Expiration Date of an Option except as provided
in an individual Option Agreement.

       6.      DURATION OF PLAN.
               ----------------
       Options may be granted under this Plan from the date of its adoption
by the Board until the effective date of its termination by the Board, but
Options granted prior to termination of this Plan shall remain effective
thereafter in accordance with their terms.  However, no Incentive Stock
Option may be granted more than ten years after the date the Plan was
originally adopted by the Board.

       7.      ADMINISTRATION OF PLAN.
               ----------------------
       7.1     The Compensation Committee shall have the power to interpret
the Plan and to make rules and establish procedures for making the various
calculations called for hereunder and otherwise for carrying out the Plan.
Any such interpretations, rules or procedures, and any decisions by the
Compensation Committee or the Board as to the persons eligible to receive
Options and the terms thereof, shall be conclusive on the Company, its
subsidiaries and their respective successors and assigns, and on the Optionee
and his or her heirs, personal and legal representatives and assigns.
       7.2     The Board may amend or terminate the Plan at any time, or
modify the terms of any individual Option Agreement, in its discretion;
however, no amendment or termination shall adversely affect the rights of an
Optionee under any Option then in effect, except as the Company and the
Optionee may otherwise agree.

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

                      NONQUALIFIED STOCK OPTION AGREEMENT
                      -----------------------------------

       THIS NONQUALIFIED STOCK OPTION AGREEMENT is entered into as of
- -------------, 19--, between Cass Commercial Corporation, a Missouri
corporation (the "Company"), and

                   -------------------------- (the "Optionee").

       WHEREAS, the Company has deemed it to be in its best interests to
promote the loyalty and facilitate the retention of its employees and the
employees of its subsidiaries in the service of the Company and its
subsidiaries, by offering such employees an increased incentive to continue
in the service of the Company and its subsidiaries and increase their efforts
for its welfare, and

       WHEREAS, in furtherance of the above purposes the Optionee's employer
has adopted the Company's 1995 Performance-Based Stock Option Plan, and has
determined to afford the Optionee an opportunity to purchase shares of common
stock of the Company pursuant to the Plan as hereafter described,

       NOW, THEREFORE, in consideration of the premises and for other good
and valuable consideration, the parties hereto do hereby agree as follows:

       1.      Definitions.  Capitalized terms not otherwise defined herein
               -----------
shall have the same meanings as they are given in the Plan.

       2.      Grant of Option.  The Company hereby grants to the Optionee an
               ---------------
Option to purchase all or any part of the number of shares of its Common
Stock set forth below (the "Option Shares"), at the purchase price set forth
below and on the other terms and conditions herein set forth.

                  TOTAL NUMBER OF OPTION SHARES:  --------

                  PURCHASE PRICE PER OPTION SHARE:  $-----

       3.      Dates When Option Exercisable.
               -----------------------------

       (a)     Except to the extent vesting is accelerated as provided in the
Plan or this Option Agreement, the Option shall vest and first become
exercisable on the following date:

                  INITIAL VESTING DATE:  JANUARY --, ----;

       (b)     Except to the extent expiration is extended as provided in the
Plan, the Option shall expire, to the extent it has not already been
exercised, at the regularly scheduled closing time of the Company's main
business office on the following date:

                  INITIAL EXPIRATION DATE:  JANUARY --, ----;

       (c)     The Company will notify the Optionee of any acceleration of the
Vesting Date or any extension of the Expiration Date as provided in the Plan,
and the reason therefor.

       (d)     Except as provided in paragraphs 3(e) and 3(f), the Option may
be exercised only if the Optionee shall have continuously served as an
employee of the Company or any of its subsidiaries from the date hereof to
and including the date of exercise.  It is expressly understood and agreed
that nothing herein is intended or shall be construed as an employment
contract or as implying any obligation on the part of the Optionee's employer
to continue the Optionee's employment for any period of time after the date
hereof.  If the Optionee is a director who is not an employee of the Company,
Cass Bank or CIS on the date of grant, then for purposes of this paragraph
and paragraphs 3(e) and 3(f), employment shall include service as a director
and termination of employment shall include the expiration of the Optionee's
term as director unless the Optionee has been reelected to a successive term.

       (e)     Notwithstanding paragraphs 3(b) and 3(d), in the event of the
death of the Optionee or termination of the Optionee's employment by reason
of his or her disability or incapacity, the Option may be exercised (but only
to the extent it was exercisable on the date of the Optionee's death or of
such termination of employment), by the Optionee's personal representative,
heir, legatee, trustee, conservator (if any) or guardian (if any),
respectively, in the manner set forth below, for a period of six (6) months
after the date of the Optionee's death or of such termination of employment.


 23

       (f)     Notwithstanding paragraph 3(d), if the Optionee's employment is
terminated by the Company other than for Cause during the period beginning
upon the first to occur of (i) a Change in Control, or (ii) the approval by
the Board of a Change in Control, or (iii) 10 days before the record date, if
any, for determining the shareholders of the Company eligible to vote on a
proposed Change in Control, or (iv) 10 days before the last date for
determining the shareholders of the Company eligible to participate in any
Change in Control in which the Company's common stock would be sold,
exchanged or converted for or into cash, property or other securities, and
ending upon the first to occur of (A) two (2) years after such Change in
Control is effected, or (B) the date such proposed Change in Control is
abandoned by the parties, then (I) to the extent the Option was not
theretofore exercisable, the Vesting Date shall be accelerated as to all
Option Shares and the Option shall be exercisable in full, and (II) the
Option may be exercised (but only to the extent it was exercisable on the
date of termination of the Optionee's employment) by the Optionee or the
Optionee's personal representative, trustee, conservator (if any) or guardian
(if any), respectively, in the manner set forth below, for a period of six
(6) months after the date of such termination of employment; and if such
Change in Control or any subsequent event has resulted in the sale, exchange
or conversion of the Common Stock for or into cash, property or other
securities, then upon exercise the Optionee shall receive in lieu of Common
Stock the cash, property or other securities which the Optionee would have
received had the Optionee exercised the Option in full 10 days before the
last date for determining the shareholders of the Company eligible to
participate in such Change in Control.  For purposes of this paragraph,
"Cause" means only conduct which is finally adjudged to be knowingly
fraudulent, deliberately dishonest or intentional misconduct.  The
Compensation Committee shall make the determination of whether Cause exists
in any particular case, and if it believes that Cause may exist it shall
provide the Optionee with notice of the reasons the Committee believes Cause
may exist and shall give the Optionee the opportunity to respond to the
allegation that Cause exists.

       4.      Method of Exercising Option.  The Optionee, or his or her
               ---------------------------
representative as permitted by paragraph 3(e) above, may exercise the Option
hereby granted on one or more occasions at his or her discretion, on each
occasion for all or any part of the Shares for which the Option is then
exercisable, by each time delivering to the main business office of the
Company, addressed to the attention of its Chief Executive Officer or
Secretary, (i) a written notice stating his or her election to exercise the
Option and the number of Option Shares to be purchased, together with (ii)
any combination of (A) cash or (B) check or (C) shares of Common Stock with
such endorsements or other transfer documentation as the Company may require,
aggregating full payment of the purchase price of the Option Shares then
being purchased plus the amount of any Federal and state withholding taxes
payable by the Company or any of its subsidiaries as a result of such
exercise; provided that shares of Common Stock may not be used in payment of
withholding taxes.  Shares of Common Stock used to exercise an Option shall
be valued at their Fair Market Value on the date of exercise.  The Option
shall be deemed to be exercised only upon receipt of such notice and payment.
The Company will advise the Optionee, upon the Optionee's reasonable prior
request, of the required amount of such taxes.

       5.      Non-Transferability of Option.  The Option may be exercised
               -----------------------------
only by the Optionee, or as permitted by paragraph 3(e) above.  The rights
granted by this Option may not be assigned, transferred, pledged or
hypothecated in any way, other than by will or by operation of law, and shall
not be subject to execution, attachment or similar process.  In the event of
the bankruptcy of the Optionee, or in the event of any prohibited assignment,
transfer, pledge, hypothecation or other disposition of the Option, or in the
event of the levy of any execution, attachment or similar process upon the
Option, the Option shall automatically expire and shall be null and void.
Notwithstanding the foregoing, however, with prior notice to the Company the
rights granted by this Option may be transferred between the Optionee in his
or her personal capacity and the Optionee as trustee of a trust (A) of which
the Optionee is both sole trustee and sole beneficiary during his or her
lifetime, and (B) all of which is treated under subpart E of Part I of
Subchapter J of Chapter 1 of Subtitle A of the Internal Revenue Code of 1986,
as amended, as owned by the Optionee.

       6.      Share Adjustments.  In the event of any stock dividend on,
               -----------------
reclassification, splitup or combination of, or other change in, the
Company's common stock, then the number or kind of Option Shares shall be
correspondingly added to, reclassified, increased, diminished or changed
proportionately, without increase or decrease in the aggregate purchase price
of all Option Shares.

       7.      No Rights of Optionee as Shareholder.  The Optionee shall have
               ------------------------------------
no rights respecting this Option or the Option Shares except as expressly set
forth herein or in the Plan, a copy of which the Optionee hereby acknowledges
having received; and the Optionee shall have no rights as a shareholder with
respect to any Option Shares until this Option has been duly exercised as to
such Option Shares in accordance with the terms hereof.  The grant of this
Option shall not affect in any way the right or power of the Company to make
adjustments, reclassifications, reorganizations or changes of its common
stock or its capital or business structure, or to merge or to consolidate, or
to dissolve or liquidate, or to sell or transfer any or all of its business
or assets.

       8.      General.  The Company shall at all times during the term of
               -------
this Option reserve and keep available a number of shares of common stock
equal to the number of Option Shares, and shall pay any original issue or
transfer taxes with respect to

                                    -2-
 24

the issue of Option Shares pursuant hereto and all other fees and expenses
necessarily incurred by the Company incurred in connection therewith.


IN WITNESS WHEREOF, the parties have executed this Nonqualified Stock Option
Agreement as of the date first above written.

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

of the Option, or in the event of the levy of any execution, attachment or
similar process upon the Option, the Option shall automatically expire and

common stock, then the number or kind of Option Shares shall be correspondingly

herein or in the Plan, a copy of which the Optionee hereby acknowledges having
received; and the Optionee shall have no rights as a shareholder with respect to
any Option Shares until this Option has been duly exercised as to such Option
Shares in accordance with the terms hereof.  The grant of this Option shall not
affect in any way the right or power of the Company to make adjustments,
reclassifications, reorganizations or changes of its common stock or its capital
or business structure, or to merge or to consolidate, or to dissolve or
liquidate, or to sell or transfer any or all of its business or assets.
