                           KANA COMMUNICATIONS, INC.

                     1997 STOCK OPTION/STOCK ISSUANCE PLAN
                     -------------------------------------
                 (Amended and Restated as of October 8, 1997)


     I.   PURPOSES OF THE PLAN

          A.   This 1997 Stock Option/Stock Issuance Plan is intended to promote
the interests of Kana Communications, Inc., a California corporation, by
providing a method whereby eligible individuals who provide valuable services to
the Corporation (or any Parent or Subsidiary) may be offered incentives and
rewards which will encourage them to acquire a proprietary interest, or
otherwise increase their proprietary interest, in the Corporation and continue
to render services to the Corporation (or any Parent or Subsidiary).

          B.   Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

     II.  STRUCTURE OF THE PLAN

          A.   The Plan shall be divided into two (2) separate equity programs:

                    -    the Option Grant Program under which eligible persons
may, at the discretion of the Plan Administrator, be granted options to purchase
shares of Common Stock, and

                    -    the Stock Issuance Program under which eligible persons
may, at the discretion of the Plan Administrator, be issued shares of Common
Stock directly, either through the immediate purchase of such shares or as a
bonus for services rendered the Corporation (or any Parent or Subsidiary).

          B.   The provisions of Articles One and Four shall apply to both
equity programs under the Plan and shall accordingly govern the interests of all
persons under the Plan.

     III. ADMINISTRATION OF THE PLAN

          A.   The Plan shall be administered by the Board.  However, any or all
administrative functions otherwise exercisable by the Board may be delegated to
the Committee.  Members of the Committee shall serve for such period of time as
the Board may determine and shall be subject to removal by the Board at any
time.  The Board may also at any time terminate the functions of the Committee
and reassume all powers and authority previously delegated to the Committee.

          B.   The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Plan and to make
such determinations under, and issue such interpretations of,


the Plan and any outstanding options or stock issuances thereunder as it may
deem necessary or advisable. Decisions of the Plan Administrator shall be final
and binding on all parties who have an interest in the Plan or any option or
stock issuance thereunder.

     IV.  ELIGIBILITY

          A.   The persons eligible to participate in the Plan are as follows:

                    (i)   Employees,

                    (ii)  non-employee members of the Board or the non-employee
     members of the board of directors of any Parent or Subsidiary, and

                    (iii) consultants and other independent advisors who provide
     services to the Corporation (or any Parent or Subsidiary).

          B.   The Plan Administrator shall have full authority to determine,
(i) with respect to the grants under the Option Grant Program, which eligible
persons are to receive the option grants, the time or times when those grants
are to be made, the number of shares to be covered by each such grant, the
status of the granted option as either an Incentive Option or a Non-Statutory
Option, the time or times when each option is to become exercisable, the vesting
schedule (if any) applicable to the option shares and the maximum term for which
the option is to remain outstanding, and (ii) with respect to stock issuances
under the Stock Issuance Program, which eligible persons are to receive such
stock issuances, the time or times when those issuances are to be made, the
number of shares to be issued to each Participant, the vesting schedule (if any)
applicable to the issued shares and the consideration to be paid by the
Participant for such shares.

          C.   The Plan Administrator shall have the absolute discretion either
to grant options in accordance with the Option Grant Program or to effect stock
issuances in accordance with the Stock Issuance Program.

     V.   STOCK SUBJECT TO THE PLAN

          A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock.  The maximum number of shares of Common
Stock which may be issued over the term of the Plan shall not exceed 4,486,000
shares.  Such share reserve includes (i) 2,700,000 shares of Common Stock that
were initially reserved for issuance under the Plan and (ii) an additional
increase of 1,786,000 shares of Common Stock authorized by the Board on October
8, 1997, and subsequently approved by the shareholders on October 8, 1997.

          B.   Shares of Common Stock subject to outstanding options shall be
available for subsequent issuance under the Plan to the extent (i) the options
expire or terminate for any reason prior to exercise in full or (ii) the options
are cancelled in accordance with the cancellation-regrant provisions of Article
Two.  Unvested shares issued under the Plan and subsequently repurchased by the
Corporation, at the option exercise or direct issue price paid per share,
pursuant

                                       2.


to the Corporation's repurchase rights under the Plan shall be added back to the
number of shares of Common Stock reserved for issuance under the Plan and shall
accordingly be available for reissuance through one or more subsequent option
grants or direct stock issuances under the Plan.

          C.  Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and/or class of securities issuable
under the Plan and (ii) the number and/or class of securities and the exercise
price per share in effect under each outstanding option under the Plan in order
to prevent the dilution or enlargement of benefits thereunder.  The adjustments
determined by the Plan Administrator shall be final, binding and conclusive.  In
no event shall any such adjustments be made in connection with the conversion of
one or more outstanding shares of the Corporation's preferred stock into shares
of Common Stock.

                                       3.


                                  ARTICLE TWO

                             OPTION GRANT PROGRAM
                             --------------------

     I.   OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; provided, however, that each such document
                                    --------
shall comply with the terms specified below.  Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   Exercise Price.
               --------------

          1.   The exercise price per share shall be fixed by the Plan
Administrator in accordance with the following provisions:

                    (i)  The exercise price per share shall not be less than
     eighty-five percent (85%) of the Fair Market Value per share of Common
     Stock on the option grant date.

                    (ii) If the person to whom the option is granted is a 10%
     Shareholder, then the exercise price per share shall not be less than one
     hundred ten percent (110%) of the Fair Market Value per share of Common
     Stock on the option grant date.

          2.   The exercise price shall become immediately due upon exercise of
the option and shall, subject to the provisions of Section I of Article Four and
the documents evidencing the option, be payable in cash or check made payable to
the Corporation.  Should the Common Stock be registered under Section 12(g) of
the 1934 Act at the time the option is exercised, then the exercise price may
also be paid as follows:

                    (i)  in shares of Common Stock held for the requisite period
     necessary to avoid a charge to the Corporation's earnings for financial
     reporting purposes and valued at Fair Market Value on the Exercise Date, or

                                       4.


                    (ii)  to the extent the option is exercised for vested
     shares, through a special sale and remittance procedure pursuant to which
     the Optionee shall concurrently provide irrevocable instructions (A) to a
     Corporation-designated brokerage firm to effect the immediate sale of the
     purchased shares and remit to the Corporation, out of the sale proceeds
     available on the settlement date, sufficient funds to cover the aggregate
     exercise price payable for the purchased shares plus all applicable
     Federal, state and local income and employment taxes required to be
     withheld by the Corporation by reason of such exercise and (B) to the
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale.

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   Exercise and Term of Options.  Each option shall be exercisable
               ----------------------------
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option grant.  However, no option shall have a term in excess of
ten (10) years measured from the option grant date.

          C.   Effect of Termination of Service.
               --------------------------------

          1.   The following provisions shall govern the exercise of any options
held by the Optionee at the time of cessation of Service or death:

                    (i)   Should the Optionee cease to remain in Service for any
     reason other than death, Disability or Misconduct, then the Optionee shall
     have a period of three (3) months following the date of such cessation of
     Service during which to exercise each outstanding option held by such
     Optionee.

                    (ii)  Should Optionee's Service terminate by reason of
     Disability, then the Optionee shall have a period of twelve (12) months
     following the date of such cessation of Service during which to exercise
     each outstanding option held by such Optionee.

                    (iii) If the Optionee dies while holding an outstanding
     option, then the personal representative of his or her estate or the person
     or persons to whom the option is transferred pursuant to the Optionee's
     will or the laws of inheritance shall have a twelve (12)-month period
     following the date of the Optionee's death to exercise such option.

                    (iv)  Under no circumstances, however, shall any such option
     be exercisable after the specified expiration of the option term.

                    (v)   During the applicable post-Service exercise period,
     the option may not be exercised in the aggregate for more than the number
     of vested

                                       5.


     shares for which the option is exercisable on the date of the Optionee's
     cessation of Service. Upon the expiration of the applicable exercise period
     or (if earlier) upon the expiration of the option term, the option shall
     terminate and cease to be outstanding for any vested shares for which the
     option has not been exercised. However, the option shall, immediately upon
     the Optionee's cessation of Service, terminate and cease to be outstanding
     with respect to any and all option shares for which the option is not
     otherwise at the time exercisable or in which the Optionee is not otherwise
     at that time vested.

                    (vi)  Should Optionee's Service be terminated for
     Misconduct, then all outstanding options held by the Optionee shall
     terminate immediately and cease to remain outstanding.

          2.   The Plan Administrator shall have the discretion, exercisable
either at the time an option is granted or at any time while the option remains
outstanding, to:

                    (i)   extend the period of time for which the option is to
     remain exercisable following Optionee's cessation of Service or death from
     the limited period otherwise in effect for that option to such greater
     period of time as the Plan Administrator shall deem appropriate, but in no
     event beyond the expiration of the option term, and/or

                    (ii)  permit the option to be exercised, during the
     applicable post-Service exercise period, not only with respect to the
     number of vested shares of Common Stock for which such option is
     exercisable at the time of the Optionee's cessation of Service but also
     with respect to one or more additional installments in which the Optionee
     would have vested under the option had the Optionee continued in Service.

          D.   Shareholder Rights.  The holder of an option shall have no
               ------------------
shareholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

          E.   Unvested Shares.  The Plan Administrator shall have the
               ---------------
discretion to grant options which are exercisable for unvested shares of Common
Stock.  Should the Optionee cease Service while holding such unvested shares,
the Corporation shall have the right to repurchase, at the exercise price paid
per share, any or all of those unvested shares.  The terms upon which such
repurchase right shall be exercisable (including the period and procedure for
exercise and the appropriate vesting schedule for the purchased shares) shall be
established by the Plan Administrator and set forth in the document evidencing
such repurchase right.  The Plan Administrator may not impose a vesting schedule
upon the option grant or any shares of Common Stock subject to that option which
is more restrictive than twenty percent (20%) per year vesting, with the initial
vesting to occur not later than one (1) year after the option grant date.
However, such limitation shall not be applicable to any option grants made to
individuals who are officers of the Corporation, non-employee Board members or
independent consultants.

                                       6.


          F.   First Refusal Rights.  Until such time as the Common Stock is
               --------------------
first registered under Section 12(g) of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Optionee (or any successor in interest) of any shares of Common Stock issued
under the Plan.  Such right of first refusal shall be exercisable in accordance
with the terms established by the Plan Administrator and set forth in the
document evidencing such right.

          G.   Limited Transferability of Options.  During the lifetime of the
               ----------------------------------
Optionee, the option shall be exercisable only by the Optionee and shall not be
assignable or transferable other than by will or by the laws of descent and
distribution following the Optionee's death.

          H.   Withholding.  The Corporation's obligation to deliver shares of
               -----------
Common Stock upon the exercise of any options granted under the Plan shall be
subject to the satisfaction of all applicable Federal, state and local income
and employment tax withholding requirements.

     II.  INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of the Plan shall be applicable to Incentive Options.  Options which
are specifically designated as Non-Statutory Options shall not be subject to the
                                                           ---
terms of this Section II.

          A.   Eligibility.  Incentive Options may only be granted to Employees.
               -----------

          B.   Exercise Price.  The exercise price per share shall not be less
               --------------
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

          C.   Dollar Limitation.  The aggregate Fair Market Value of the shares
               -----------------
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one (1) calendar year
shall not exceed the sum of One Hundred Thousand Dollars ($100,000).  To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

          D.   10% Shareholder.  If any Employee to whom an Incentive Option is
               ---------------
granted is a 10% Shareholder, then the option term shall not exceed five (5)
years measured from the option grant date.

                                       7.


     III. CORPORATE TRANSACTION

          A.   The shares subject to each option outstanding under the Plan at
the time of a Corporate Transaction shall automatically vest in full so that
each such option shall, immediately prior to the effective date of the Corporate
Transaction, become fully exercisable for all of the shares of Common Stock at
the time subject to that option and may be exercised for any or all of those
shares as fully-vested shares of Common Stock.  However, the shares subject to
an outstanding option shall not vest on such an accelerated basis if and to the
extent:  (i) such option is assumed by the successor corporation (or parent
thereof) in the Corporate Transaction and the Corporation's repurchase rights
with respect to the unvested option shares are concurrently assigned to such
successor corporation (or parent thereof) or (ii) such option is to be replaced
with a cash incentive program of the successor corporation which preserves the
spread existing on the unvested option shares at the time of the Corporate
Transaction and provides for subsequent payout in accordance with the same
vesting schedule applicable to those unvested option shares or (iii) the
acceleration of such option is subject to other limitations imposed by the Plan
Administrator at the time of the option grant.

          B.   All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Corporate Transaction,
except to the extent: (i) those repurchase rights are assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.

          C.   Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction, had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the number and class of
securities available for issuance under the Plan following the consummation of
such Corporate Transaction and (ii) the exercise price payable per share under
each outstanding option, provided the aggregate exercise price payable for such
                         --------
securities shall remain the same.

          E.   The Plan Administrator shall have the discretion, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to provide for the automatic acceleration (in whole or in part) of
one or more outstanding options (and the immediate termination of the
Corporation's repurchase rights with respect to the shares subject to those
options) upon the occurrence of a Corporate Transaction, whether or not those
options are to be assumed in the Corporate Transaction.

                                       8.


          F.   The Plan Administrator shall also have full power and authority,
exercisable either at the time the option is granted or at any time while the
option remains outstanding, to structure such option so that the shares subject
to that option will automatically vest on an accelerated basis should the
Optionee's Service terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Corporate Transaction in which the option is assumed and the
repurchase rights applicable to those shares do not otherwise terminate.  Any
option so accelerated shall remain exercisable for the fully-vested option
shares until the earlier of (i) the expiration of the option term or (ii) the
                 -------
expiration of the one (1)-year period measured from the effective date of the
Involuntary Termination.  In addition, the Plan Administrator may provide that
one or more of the Corporation's outstanding repurchase rights with respect to
shares held by the Optionee at the time of such Involuntary Termination shall
immediately terminate on an accelerated basis, and the shares subject to those
terminated rights shall accordingly vest at that time.

          G.   The portion of any Incentive Option accelerated in connection
with a Corporate Transaction shall remain exercisable as an Incentive Option
only to the extent the applicable One Hundred Thousand Dollar limitation is not
exceeded.  To the extent such dollar limitation is exceeded, the accelerated
portion of such option shall be exercisable as a Non-Statutory Option under the
Federal tax laws.

          H.   The grant of options under the Plan shall in no way affect the
right of the Corporation to adjust, reclassify, reorganize or otherwise change
its capital or business structure or to merge, consolidate, dissolve, liquidate
or sell or transfer all or any part of its business or assets.

     IV.  CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Plan and to grant in
substitution therefor new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                                       9.


                                 ARTICLE THREE

                            STOCK ISSUANCE PROGRAM
                            ----------------------


     I.   STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.

          A.   Purchase Price.
               --------------

          1.   The purchase price per share shall be fixed by the Plan
Administrator but shall not be less than eighty-five percent (85%) of the Fair
Market Value per share of Common Stock on the issue date.  However, the purchase
price per share of Common Stock issued to a 10% Shareholder shall not be less
than one hundred and ten percent (110%) of such Fair Market Value.

          2.   Subject to the provisions of Section I of Article Four, shares of
Common Stock may be issued under the Stock Issuance Program for any of the
following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

               (i)  cash or check made payable to the Corporation, or

               (ii) past services rendered to the Corporation (or any Parent or
     Subsidiary).

          B.   Vesting Provisions.
               ------------------

          1.   Shares of Common Stock issued under the Stock Issuance Program
may, in the discretion of the Plan Administrator, be fully and immediately
vested upon issuance or may vest in one or more installments over the
Participant's period of Service or upon attainment of specified performance
objectives.  However, the Plan Administrator may not impose a vesting schedule
upon any stock issuance effected under the Stock Issuance Program which is more
restrictive than twenty percent (20%) per year vesting, with initial vesting to
occur not later than one (1) year after the issuance date.  Such limitation
shall not apply to any Common Stock issuances made to the officers of the
Corporation, non-employee Board members or independent consultants.

                                      10.


          2.   Any new, substituted or additional securities or other property
(including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock by reason of any stock dividend, stock split,
recapitalization, combination of shares, exchange of shares or other change
affecting the outstanding Common Stock as a class without the Corporation's
receipt of consideration shall be issued subject to (i) the same vesting
requirements applicable to the Participant's unvested shares of Common Stock and
(ii) such escrow arrangements as the Plan Administrator shall deem appropriate.

          3.   The Participant shall have full shareholder rights with respect
to any shares of Common Stock issued to the Participant under the Stock Issuance
Program, whether or not the Participant's interest in those shares is vested.
Accordingly, the Participant shall have the right to vote such shares and to
receive any regular cash dividends paid on such shares.

          4.   Should the Participant cease to remain in Service while holding
one or more unvested shares of Common Stock issued under the Stock Issuance
Program or should the performance objectives not be attained with respect to one
or more such unvested shares of Common Stock, then those shares shall be
immediately surrendered to the Corporation for cancellation, and the Participant
shall have no further shareholder rights with respect to those shares.  To the
extent the surrendered shares were previously issued to the Participant for
consideration paid in cash or cash equivalent (including the Participant's
purchase-money indebtedness), the Corporation shall repay to the Participant the
cash consideration paid for the surrendered shares and shall cancel the unpaid
principal balance of any outstanding purchase-money note of the Participant
attributable to such surrendered shares.

          5.   The Plan Administrator may in its discretion waive the surrender
and cancellation of one or more unvested shares of Common Stock (or other assets
attributable thereto) which would otherwise occur upon the non-completion of the
vesting schedule applicable to such shares.  Such waiver shall result in the
immediate vesting of the Participant's interest in the shares of Common Stock as
to which the waiver applies.  Such waiver may be effected at any time, whether
before or after the Participant's cessation of Service or the attainment or non-
attainment of the applicable performance objectives.

          C.   First Refusal Rights.  Until such time as the Common Stock is

first registered under Section 12(g) of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the

     II.  CORPORATE TRANSACTION

          A.   Upon the occurrence of a Corporate Transaction, all outstanding
repurchase rights under the Stock Issuance Program shall terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, except to the extent: (i) those repurchase
rights are assigned to the successor corporation (or parent thereof) in
connection with such Corporate Transaction or (ii) such accelerated vesting is
precluded by other limitations imposed by the Plan Administrator at the time the
repurchase right is issued.

          B.   The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase rights with respect to those shares remain
outstanding, to provide that those rights shall automatically terminate on an
accelerated basis, and the shares of Common Stock subject to those terminated
rights shall immediately vest, in the event the Participant's Service should
subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Corporate Transaction in which those repurchase rights are assigned
to the successor corporation (or parent thereof).

     III. SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

     I.   FINANCING

          The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price or the purchase price for shares issued to such person
under the Plan by delivering a full-recourse, interest-bearing promissory note
payable in one or more installments and secured by the purchased shares.
However, any promissory note delivered by a consultant must be secured by
collateral in addition to the purchased shares of Common Stock.  In no event
shall the maximum credit available to the Optionee or Participant exceed the sum
                                                                             ---
of (i) the aggregate option exercise price or purchase price payable for the

tax liability incurred by the Optionee or the Participant in connection with the
option exercise or share purchase.

     II.  EFFECTIVE DATE AND TERM OF PLAN

          A.   The Plan shall become effective upon adoption by the Board on May
22, 1997, but no option granted under the Plan may be exercised, and no shares
shall be issued under the Plan, until the Plan is approved by the Corporation's
shareholders.  If such shareholder approval is not obtained within twelve (12)
months after the date of the Board's adoption of the Plan, then all options
previously granted under the Plan shall terminate and cease to be outstanding,
and no further options shall be granted and no shares shall be issued under the
Plan.  Subject to such limitation, the Plan Administrator may grant options and
issue shares under the Plan at any time after the effective date of the Plan and
before the date fixed herein for termination of the Plan.

          B.   The Plan shall terminate upon the earliest to occur of (i) the
                                                 --------
expiration of the ten (10)-year period measured from the May 22, 1997 effective
date of the Plan, (ii) the date on which all shares available for issuance under
the Plan shall have been issued as vested shares or (iii) the termination of all
outstanding options in connection with a Corporate Transaction.  All options and
unvested stock issuances outstanding at that time under the Plan shall continue
to have full force and effect in accordance with the provisions of the documents
evidencing such options or issuances.

                                      13.


     III. AMENDMENT OF THE PLAN

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects.  However, no such amendment
or modification shall adversely affect the rights and obligations with respect
to options or unvested stock issuances at the time outstanding under the Plan
unless the Optionee or the Participant consents to such amendment or
modification.  In addition, certain amendments may require shareholder approval
pursuant to applicable laws and regulations.

          B.   The Plan was amended and restated by the Board on October 8, 1997
to increase the maximum number of shares of Common Stock authorized for issuance
over the term of the Plan by an additional 1,786,000 shares to 4,486,000 shares.
This amendment and restatement of the Plan was approved by the Company's
shareholders on October 8, 1997.

          C.   Options may be granted under the Option Grant Program and shares
may be issued under the Stock Issuance Program which are in each instance in
excess of the number of shares of Common Stock then available for issuance under
the Plan, provided any excess shares actually issued under those programs shall
be held in escrow until there is obtained shareholder approval of an amendment
sufficiently increasing the number of shares of Common Stock available for
issuance under the Plan.  If such shareholder approval is not obtained within
twelve (12) months after the date the first such excess issuances are made, then
(i) any unexercised options granted on the basis of such excess shares shall
terminate and cease to be outstanding and (ii) the Corporation shall promptly
refund to the Optionees and the Participants the exercise or purchase price paid
for any excess shares issued under the Plan and held in escrow, together with
interest (at the applicable Short Term Federal Rate) for the period the shares
were held in escrow, and such shares shall thereupon be automatically cancelled
and cease to be outstanding.

     IV.  USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

     V.   WITHHOLDING

          The Corporation's obligation to deliver shares of Common Stock upon
the exercise of any options or upon the issuance or vesting of any shares issued
under the Plan shall be subject to the satisfaction of all applicable Federal,
state and local income and employment tax withholding requirements.

     VI.  REGULATORY APPROVALS

          The implementation of the Plan, the granting of any options under the
Plan and the issuance of any shares of Common Stock (i) upon the exercise of any
option or (ii) under the Stock Issuance Program shall be subject to the
Corporation's procurement of all approvals and permits

                                      14.


required by regulatory authorities having jurisdiction over the Plan, the
options granted under it and the shares of Common Stock issued pursuant to it.

     VII.  NO EMPLOYMENT OR SERVICE RIGHTS

           Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

     VIII. FINANCIAL REPORTS

           The Corporation shall deliver a balance sheet and an income statement
