EXHIBIT 10.1 - EXECUTION COPY

                              SETTLEMENT AGREEMENT

         SETTLEMENT AGREEMENT, dated as of January 31, 2001, by and among
PLACEMENT 2000.COM, INC., a Delaware corporation (the "COMPANY"), AMERICAN
VANTAGE COMPANIES, a Nevada corporation ("AMERICAN VANTAGE") and MICHAEL
WOLOSHIN ("WOLOSHIN"). For purposes of this Agreement, an "AFFILIATE" of a
person is any person that controls, is controlled by, or is under common control
with such other person. A "PERSON" includes any natural person and any
corporation, partnership, joint venture, limited liability company, governmental
agency or other legal entity.

                                    RECITALS

         The Company, American Vantage and Woloshin entered into a Stock
Purchase Agreement, dated as of December 1, 1999 (the "PURCHASE AGREEMENT"),
pursuant to which American Vantage purchased shares of the Company's capital
stock such that after such purchase American Vantage owned eighty percent (80%)
of the Company's issued and outstanding common stock (collectively, the
"SHARES"). Under the Purchase Agreement, American Vantage agreed to deposit Five
Hundred Thousand Dollars ($500,000) in escrow pursuant to the terms of an Escrow
Agreement, dated as of December 1, 1999 (the "1999 ESCROW AGREEMENT"), among the
Company, American Vantage, and Security Trust Company of Nevada, as Escrow
Agent, pursuant to which the Escrow Agent agreed to disburse the Escrow Funds
(as defined in the 1999 Escrow Agreement) as provided in Section 1.1(a) of the
Purchase Agreement.

         Certain disputes have arisen between Woloshin and American Vantage as
to the Company's rights to the Escrow Funds and Woloshin's management and
operation of the Company. Accordingly, the parties have agreed to resolve such
disputes by providing that American Vantage will transfer the Shares to Woloshin
and pay him $125,000, American Vantage will cancel all stock options granted to
Woloshin, the parties and certain other persons will exchange general releases,
Woloshin and the Company will indemnify American Vantage against any and all
claims, and the parties will direct the Escrow Agent to distribute the Escrow
Funds to American Vantage under the 1999 Escrow Agreement, all in accordance
with the terms of this Agreement.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein set forth and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree as
follows:

1.       TRANSFER OF THE SHARES TO WOLOSHIN.

         Concurrently with the execution and delivery of this Agreement,
American Vantage is delivering to Woloshin one or more certificates representing
the Shares, together with Stock Powers duly executed in blank on behalf of
American Vantage. American Vantage hereby represents and warrants to Woloshin
that the Shares represent all of the capital stock that American Vantage owns in
the Company and that American Vantage does not own any warrants, options or
other rights to purchase, or any securities convertible into or exchangeable for
capital stock of the Company. American Vantage is transferring the Shares to
Woloshin free and clear of any liens, claims, encumbrances, or restrictions
whatsoever, other than those imposed on the transfer of the Shares under federal
and state securities laws.

2.       PAYMENT TO WOLOSHIN.

         Concurrently with the execution and delivery of this Agreement,
American Vantage is delivering to Woloshin a good check in the amount of One
Hundred Twenty-Five Thousand Dollars ($125,000), subject to collection.

3.       TERMINATION OF WOLOSHIN OPTIONS.

are null, void and of no effect. Concurrently with the execution and delivery of
this Agreement, Woloshin is delivering to American Vantage all original Option
Agreements representing the options granted to him by American Vantage.

hereby consents to such termination as provided in clause (ii) of Section 5.2 of
the 1999 Escrow Agreement. The Company, American Vantage, Woloshin and Cooper

6.      INDEMNIFICATION.

        (a)    Woloshin and the Company, jointly and severally, hereby agree to
indemnify, hold harmless and defend American Vantage and any subsidiaries and
Affiliates of American Vantage and any of their respective partners, members,
managers, directors, shareholders, officers, employees, attorneys, agents,
contractors, consultants and representatives (collectively, "AMERICAN VANTAGE
INDEMNIFIED PERSONS") from and against any and all demands, claims, actions or
causes of action, assessments, losses, damages, liabilities, judgments, costs
and expenses, including, without limitation, interest, penalties and reasonable
attorneys' fees and expenses (collectively, "CLAIMS") asserted against,
resulting to, imposed upon or incurred by the American Vantage Indemnified
Persons, directly or indirectly, by reason of or arising from (i) any act taken
by the Company or any of its representatives or any omission by the Company or
any of its representatives to take any act, regardless of when such act or
omission occurred or (ii) any Claim by a Company stockholder other than American
Vantage against such American Vantage Indemnified Person.

        (b)    The obligation of Woloshin or the Company, as applicable (the
"INDEMNIFYING PERSON"), to indemnify, hold harmless, defend and reimburse an
American Vantage Indemnified Person under Section 6(a) hereof with respect to
any claim for which such indemnification is sought (an "INDEMNIFICATION CLAIM")
is conditioned upon receiving from such American Vantage Indemnified Person
written notice of such Indemnification Claim promptly after such American
Vantage Indemnified Person becomes aware of such Indemnification Claim;
provided, however, that any delay in giving such notice shall not release an
Indemnifying Party from its obligations under this Section 6 except to the
extent and only to the extent that such American Vantage Indemnified Person was
prejudiced by such delay. The Indemnifying Person shall at its sole expense
defend, contest, settle or otherwise protect against any Claim (including
without limitation by taking reasonably necessary or appropriate action to
remediate) with legal counsel or other appropriate consultants or experts
(collectively, "EXPERTS") of its own selection that are reasonably satisfactory
to such American Vantage Indemnified Person. The Indemnified Person shall have
the right, but not the obligation, to (i) elect to defend, contest, settle or
otherwise protect against such claims with Experts of its own choice, (ii)
participate in the defense, contest, settlement or other protection of such
claims with Experts of its own choice, and (iii) assert any and all defenses,
cross claims or counterclaims it may have; provided, however, that such
election, participation and assertion shall be at the Indemnified Person's sole
cost and expense, notwithstanding anything in this Agreement to the contrary,
unless (x) the American Vantage Indemnified Person and Indemnifying Person have
agreed otherwise, (y) representation of both parties by the same Experts would
be inappropriate due to actual or potential differing interests between them or
(z) the Indemnifying Person fails to take reasonably necessary or appropriate
action and employ appropriate Experts that are reasonably satisfactory to the
American Vantage Indemnified Person within a reasonable period of time. The
Indemnifying Person shall not be liable for any settlement of an Indemnified
Claim effected without its prior written consent (which shall not be
unreasonably withheld, delayed or conditioned). The Indemnifying Person shall
not settle any Claim without the relevant American Vantage Indemnified Person's
prior written consent (which shall not be unreasonably withheld, conditioned or
delayed) unless the settlement includes an unconditional general release of such
American Vantage Indemnified Person from all Claims that are the subject matter
of the proceeding. The American Vantage Indemnified Person shall cooperate, and
shall cause each other American Vantage Indemnified Person to at all times
cooperate, in all reasonable ways with, make (subject to the assertion of
attorney-client and other applicable privileges) its respective relevant files
and records available for inspection and copying by, and make its employees
available or otherwise render reasonable assistance to, the Indemnifying Person
in its defense, contest, settlement or protection of any Indemnified Claim
subject to indemnification hereunder.

7.      AGREEMENT NOT TO SUE.

        (a)     In consideration of this Agreement, Woloshin and the Company
each agrees that he or it will not commence any action or proceeding against
American Vantage, any subsidiary or Affiliate thereof, or any of their
respective partners, members, managers, directors, shareholders, officers,
employees, attorneys, agents, contractors, consultants or representatives, in
any court of law or before any administrative agency or arbitration tribunal
based on any action or omission occurring prior to his execution and delivery of
this Agreement, whether arising out of the Purchase Agreement, the 1999 Escrow
Agreement, the Employment Agreement, dated as of December 1, 1999, between the
Company and Woloshin (the "EMPLOYMENT AGREEMENT"), the Non-Competition
Agreement, dated as of December 1, 1999, among American Vantage, the Company and
Woloshin (the "NON-COMPETITION AGREEMENT"), the Non-Qualified Stock Option
Agreement, dated as of December 1, 1999, between American
<PAGE>   4
Vantage and Woloshin (the "STOCK OPTION AGREEMENT"), or otherwise, including, in
the case of Woloshin, in connection with his being an officer, director,
employee or stockholder of the Company or American Vantage.

        (b)    In consideration of this Agreement, American Vantage agrees that
it will not commence any action or proceeding against Woloshin or the Company in
any court of law or before any administrative agency based on any action or
omission occurring prior to their execution and delivery of this Agreement,
whether arising out of the Purchase Agreement, the 1999 Escrow Agreement, the
Employment Agreement, the Non-Competition Agreement, the Stock Option Agreement,
or otherwise, including, in the case of Woloshin, in connection with his being
an officer, director, employee or stockholder of the Company or American
Vantage.

        (c)    Each of the parties hereto acknowledges and agrees that if he or
it (each, a "BREACHING PARTY") breaches, or threatens to commit a breach of, any
of the provisions of this Section 7 (the "AGREEMENT NOT TO Sue"), the other
party or parties (each, a "NON-BREACHING PARTY") shall have no adequate remedy
at law. Therefore, the Non-Breaching Party shall be entitled to enforce the
Agreement Not to Sue by temporary or permanent injunctive or mandatory relief
obtained in any court of competent jurisdiction without the necessity of proving
damages, posting any bond or other security, and without prejudice to any other
rights and remedies which may be available at law or in equity.

8.      PARTICIPATION IN EVCI JOINT VENTURE.

        If Company or any Affiliate of the Company or Woloshin enters into a
joint venture with Education Video Conferencing, Inc. or any Affiliate thereof,
whether through a corporation, partnership, limited liability company, or other
business entity or contractual relationship (the "EVCI JOINT VENTURE") within
one (1) year after the date hereof, Woloshin and the Company will cause the EVCI
Joint Venture to grant American Vantage or an Affiliate an option to purchase a
one-third (1/3) equity interest in the EVCI Joint Venture, such equity interest
to be the same as the equity interest of EVCI and the Company (or their
respective Affiliates). Such option will provide that American Vantage or its
Affiliate can exercise such option for a period of two years after the date of
grant and may purchase such equity interest for One Hundred Dollars ($100) and
will have customary anti-dilution provisions. In addition, Woloshin and the
Company will cause the EVCI Joint Venture to issue American Vantage a promissory
note in the principal amount of One Hundred Fifty-Five Thousand Dollars
($155,000), payable one (1) year after the EVCI Joint Venture is organized and
bearing interest at the prime rate.

                               GENERAL PROVISIONS

I. PURPOSE OF THE PLAN

      This Amended and Restated 1998 Stock Incentive Plan (the "Plan") is
intended to promote the interests of Discovery Laboratories, Inc., a Delaware
corporation, by providing eligible persons with the opportunity to acquire a
proprietary interest, or otherwise increase their proprietary interest, in the
Corporation as an incentive for them to remain in the service of the
Corporation.

      The Plan amends and restates the Corporation's 1998 Stock Incentive Plan
and shall serve as the successor to the Corporation's 1995 Stock Option Plan and
1993 Stock Option Plan (the "Predecessor Plans"). No further option grants shall
be made under the Predecessor Plans after the Initial Approval Date. All options
outstanding under the Predecessor Plans on the Initial Approval Date are
incorporated into the Plan and shall be treated as outstanding options under the
Plan. However, each outstanding option so incorporated shall continue to be
governed solely by the terms of the documents evidencing such option, and no
provision of the Plan shall be deemed to affect or otherwise modify the rights
or obligations of the holders of such incorporated options with respect to their
acquisition of shares of Common Stock.

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

II. STRUCTURE OF THE PLAN

      A. The Plan shall be divided into three separate equity programs:

                  (i) the Discretionary Option Grant Program under which
      eligible persons may, at the discretion of the Plan Administrator, be
      granted options to purchase shares of Common Stock,

                  (ii) 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), and

                  (iii) the Automatic Option Grant Program under which eligible
      non-employee board members shall automatically receive option grants at
      periodic intervals to purchase shares of Common Stock.

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

III. ADMINISTRATION OF THE PLAN

      A. The Board shall have authority to administer the Discretionary Option
Grant and Stock Issuance Programs with respect to Section 16 Insiders but may
delegate such authority to the Primary Committee. Administration of the
Discretionary Option Grant and Stock Issuance Programs with respect to all other
persons eligible to participate in those programs may, at the Board's
discretion, be vested in the Primary Committee or a Secondary Committee, or the
Board may retain the power to administer those programs with respect to all such
persons.

                                       1
<PAGE>

      B. Members of the Primary Committee or any Secondary Committee shall serve
for such period of time as the Board may determine and may be removed by the
Board at any time. The Board may also at any time terminate the functions of any
Secondary Committee and reassume all powers and authority previously delegated
to such committee.

      C. Each Plan Administrator shall, within the scope of its administrative
functions under the Plan, 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 Discretionary Option Grant and
Stock Issuance Programs and to make such determinations under, and issue such
interpretations of, the provisions of such programs and any outstanding options
or stock issuances thereunder as it may deem necessary or advisable. Decisions
of the Plan Administrator within the scope of its administrative functions under
the Plan shall be final and binding on all parties who have an interest in the
Discretionary Option Grant and Stock Issuance Programs under its jurisdiction or
any option or stock issuance thereunder.

      D. Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee. No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants or stock issuances under the
Plan.

IV. ELIGIBILITY

      A. The persons eligible to participate in the Discretionary Option Grant
and Stock Issuance Programs are as follows:

                  (i) Employees,

                  (ii) non-employee members of the Board or 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. Each Plan Administrator shall, within the scope of its administrative
jurisdiction under the Plan, have full authority to determine, (i) with respect
to the option grants under the Discretionary Option Grant Program, which
eligible persons are to receive option grants, the time or times when such
option 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 stock issuances, the time or times when such 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
for such shares.

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

      D. Only non-employee members of the Board shall be eligible to participate
in the Automatic Option Grant 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, including shares repurchased by the
Corporation on the open market. The maximum number of shares of Common Stock
reserved for issuance over the term of the Plan shall not exceed

                                       2
<PAGE>

3,000,000 shares. Such authorized share reserve is comprised of (i) the number
of shares which remained available for issuance under the Predecessor Plans as
of the Initial Approval Date, comprised of the shares subject to the outstanding
options incorporated into the 1998 Stock Incentive Plan upon its initial
approval by the stockholders of the Corporation and outstanding options issued
subsequent to the Initial Approval Date, but not in excess of the additional
shares which were otherwise available for future grant under the Predecessor
Plans as of the Initial Approval Date (403,162 shares in the aggregate), plus
(ii) an additional 1,022,566 shares which became issuable under the 1998 Stock
Incentive Plan on the Initial Approval Date plus (iii) an additional increase of
775,231 shares authorized by the Board on December 7, 1998, and approved by the
Corporation's stockholders at the 1999 Annual Meeting, plus (iv) an additional
increase of 799,041 shares authorized by the Board on March 17, 2000, subject to
approval by the Corporation's shareholders at the 2000 Annual Meeting.

      B. No one person participating in the Plan may receive options, separately
exercisable stock appreciation rights and direct stock issuances for more than
250,000 shares of Common Stock in the aggregate per calendar year, beginning
with the 1998 calendar year.

      C. Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plans) shall be
available for subsequent issuance under the Plan to the extent those options
expire or terminate for any reason prior to exercise in full. Unvested shares
issued under the Plan and subsequently cancelled or repurchased by the
Corporation, at the original issue price paid per share, pursuant 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. However, should the exercise
price of an option under the Plan be paid with shares of Common Stock or should
shares of Common Stock otherwise issuable under the Plan be withheld by the
Corporation in satisfaction of the withholding taxes incurred in connection with
the exercise of an option or the vesting of a stock issuance under the Plan,
then the number of shares of Common Stock available for issuance under the Plan
shall be reduced by the gross number of shares for which the option is exercised
or which vest under the stock issuance, and not by the net number of shares of
Common Stock issued to the holder of such option or stock issuance.

      D. If any change is 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, (ii)
the number and/or class of securities for which any one person may be granted
options, separately exercisable stock appreciation rights and direct stock
issuances under this Plan per calendar year, (iii) the number and/or class of
securities for which grants are subsequently to be made under the Automatic
Option Grant Program to new and continuing non-employee Board members, (iv) the
number and/or class of securities and the exercise price per share in effect
under each outstanding option under the Plan and (v) the number and/or class of
securities and price per share in effect under each outstanding option
incorporated into this Plan from the Predecessor Plan. Such adjustments to the
outstanding options are to be effected in a manner which shall preclude the
enlargement or dilution of rights and benefits under such options. The
adjustments determined by the Plan Administrator shall be final, binding and
conclusive.

                                   ARTICLE TWO
                       DISCRETIONARY 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.

                                       3
<PAGE>

      A. Exercise Price.

            1. The exercise price per share shall be fixed by the Plan
Administrator but shall not be less than one hundred percent (100%) 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 Five and
the documents evidencing the option, be payable in one or more of the forms
specified below:

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

                  (ii) 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

                  (iii) 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 written instructions to
      (a) 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) 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. 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) Any option outstanding at the time of the Optionee's
      cessation of Service for any reason shall remain exercisable for such
      period of time thereafter as shall be determined by the Plan Administrator
      and set forth in the documents evidencing the option, but no such option
      shall be exercisable after the expiration of the option term.

                  (ii) Any option exercisable in whole or in part by the
      Optionee at the time of death may be subsequently exercised by the
      personal representative of the Optionee's estate or by the person or
      persons to whom the option is transferred pursuant to the Optionee's will
      or in accordance with the laws of descent and distribution.

                  (iii) During the applicable post-Service exercise period, the
      option may not be exercised in the aggregate for more than the number of
      vested 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 to the extent the option is not otherwise at that
      time exercisable for vested shares.

                                       4
<PAGE>

                  (vi) Should the 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 complete 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 the Optionee's cessation of Service from the
      limited exercise 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
      had the Optionee continued in Service.

      D. Stockholder Rights. The holder of an option shall have no stockholder
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. Repurchase Rights. 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.

      F. Limited Transferability of Options. During the lifetime of the
Optionee, Incentive Options 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. However, a Non-Statutory Option
may, in connection with the Optionee's estate plan, be assigned in whole or in
part during the Optionee's lifetime to one or more members of the Optionee's
immediate family or to a trust established exclusively for one or more such
family members. The assigned portion may only be exercised by the person or
persons who acquire a proprietary interest in the option pursuant to the
assignment. The terms applicable to the assigned portion shall be the same as
those in effect for the option immediately prior to such assignment and shall be
set forth in such documents issued to the assignee as the Plan Administrator may
deem appropriate.

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
Articles One, Two and Five shall be applicable to Incentive Options. Options
which are specifically designated as Non-Statutory Options when issued under the
Plan shall not be subject to the terms of this Section II.

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

                                       5
<PAGE>

      B. 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 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.

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

III. CORPORATE TRANSACTION/CHANGE IN CONTROL

      A. In the event of any Corporate Transaction, each outstanding option
shall automatically accelerate so that each such option shall, immediately prior
to the effective date of the Corporate Transaction, become fully exercisable
with respect to the total number of shares of Common Stock at the time subject
to such option and may be exercised for any or all of those shares as
fully-vested shares of Common Stock. However, an outstanding option shall not so
accelerate if and to the extent: (i) such option is, in connection with the
Corporate Transaction, either to be assumed by the successor corporation (or
parent thereof) or to be replaced with a comparable option to purchase shares of
the capital stock of the successor corporation (or parent thereof), (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 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. The determination of
option comparability under clause (i) above shall be made by the Plan
Administrator, and its determination shall be final, binding and conclusive.

      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 to be 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. 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 of one or more
outstanding options upon the occurrence of a Corporate Transaction, whether or
not those options are to be assumed or replaced in the Corporate Transaction.

      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 to reflect such Corporate Transaction shall also be made to (i) the
exercise price payable per share under each outstanding option, provided the
aggregate exercise price payable for such securities shall remain the same, (ii)
the maximum number and/or class of securities available for issuance over the
remaining term of the Plan and (iii) the maximum number and/or class of
securities for which any one person may be granted stock options, separately
exercisable stock appreciation rights and direct stock issuances under the Plan
per calendar year.

                                       6
<PAGE>

      E. Notwithstanding Section III.A. of this Article Two, the Plan
Administrator shall have the discretionary authority, exercisable either at the
time the option is granted or at any time while the option remains outstanding,
to provide for the automatic acceleration of one or more outstanding options
under the Discretionary Option Grant Program upon the occurrence of a Corporate
Transaction, whether or not those options are to be assumed or replaced in the
Corporate Transaction. 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 Corporate Transaction shall
immediately terminate, and the shares subject to those terminated repurchase
rights shall accordingly vest in full, even in the event the options are to be
assumed.

      F. The Plan Administrator shall have full power and authority exercisable,
either at the time the option is granted or at any time while the option remains
outstanding, to provide for the automatic acceleration of one or more
outstanding options under the Discretionary Option Grant Program in the event
the Optionee's Service terminates 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 options are assumed or replaced
and do not otherwise accelerate. Any options so accelerated shall remain
exercisable for fully-vested 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, and the shares subject
to those terminated repurchase rights shall accordingly vest in full.

      G. The Plan Administrator shall have full power and authority, exercisable
either at the time the option is granted or at any time while the option remains
outstanding, to provide for the automatic acceleration of one or more
outstanding options under the Discretionary Option Grant Program upon (i) a
Change in Control or (ii) the termination of the Optionee's Service by reason of
an Involuntary Termination within a designated period (not to exceed eighteen
(18) months) following the effective date of such Change in Control. Each option
so accelerated shall remain exercisable for fully-vested 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 Optionee's cessation
of Service. 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 Change in Control or Involuntary Termination
shall immediately terminate, and the shares subject to those terminated
repurchase rights shall accordingly vest in full.

      H. The portion of any Incentive Option accelerated in connection with a
Corporate Transaction or Change in Control 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.

      I. The outstanding options 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 Discretionary Option
Grant Program (including outstanding options incorporated from the Predecessor
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 grant date.

V. STOCK APPRECIATION RIGHTS

      A. The Plan Administrator shall have full power and authority to grant to
selected Optionees tandem stock appreciation rights and/or limited stock
appreciation rights.

                                       7
<PAGE>

      B. The following terms shall govern the grant and exercise of tandem stock
appreciation rights:

                  (i) One or more Optionees may be granted the right,
      exercisable upon such terms as the Plan Administrator may establish, to
      elect between the exercise of the underlying option for shares of Common
      Stock and the surrender of that option in exchange for a distribution from
      the Corporation in an amount equal to the excess of (a) the Fair Market
      Value (on the option surrender date) of the number of shares in which the
      Optionee is at the time vested under the surrendered option (or
      surrendered portion thereof) over (b) the aggregate exercise price payable
      for such shares.

                  (ii) No such option surrender shall be effective unless it is
      approved by the Plan Administrator, either at the time of the actual
      option surrender or at any earlier time. If the surrender is so approved,
      then the distribution to which the Optionee shall be entitled may be made
      in shares of Common Stock valued at Fair Market Value on the option
      surrender date, in cash, or partly in shares and partly in cash, as the
      Plan Administrator shall in its sole discretion deem appropriate.

                  (iii) If the surrender of an option is not approved by the
      Plan Administrator, then the Optionee shall retain whatever rights the
      Optionee had under the surrendered option (or surrendered portion thereof)
      on the option surrender date and may exercise such rights at any time
      prior to the later of (a) five (5) business days after the receipt of the
      rejection notice or (b) the last day on which the option is otherwise
      exercisable in accordance with the terms of the documents evidencing such
      option, but in no event may such rights be exercised more than ten (10)
      years after the option grant date.

      C. The following terms shall govern the grant and exercise of limited
stock appreciation rights:

                  (i) One or more Section 16 Insiders may be granted limited
      stock appreciation rights with respect to their outstanding options.

                  (ii) Upon the occurrence of a Hostile Take-Over, each
      individual holding one or more options with such a limited stock
      appreciation right shall have the unconditional right (exercisable for a
      thirty (30)-day period following such Hostile Take-Over) to surrender each
      such option to the Corporation, to the extent the option is at the time
      exercisable for vested shares of Common Stock. In return for the
      surrendered option, the Optionee shall receive a cash distribution from
      the Corporation in an amount equal to the excess of (A) the Take-Over
      Price of the shares of Common Stock which are at the time vested under
      each surrendered option (or surrendered portion thereof) over (B) the
      aggregate exercise price payable for such shares. Such cash distribution
      shall be paid within five (5) days following the option surrender date.

                  (iii) The balance of the option (if any) shall remain
      outstanding and exercisable in accordance with the documents evidencing
      such option.

                                 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.

                                       8
<PAGE>

      A. Purchase Price.

            1. The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the issuance date.

            2. Subject to the provisions of Section I of Article Five, 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.

            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 stockholder 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 stockholder 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 the surrendered shares.

            5. The Plan Administrator may in its discretion waive the surrender
and cancellation of one or more unvested shares of Common Stock which would
otherwise occur upon the cessation of the Participant's Service or the
non-attainment of the performance objectives applicable to those shares. Such
waiver shall result in the immediate vesting of the Participant's interest in
the shares 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.

II. CORPORATE TRANSACTION/CHANGE IN CONTROL

      A. All of the Corporation's outstanding repurchase rights under the Stock
Issuance Program shall terminate automatically, and all 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 to be 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 in the Stock Issuance Agreement.

                                       9
<PAGE>

      B. The Plan Administrator shall have the discretion, exercisable either at
the time the unvested shares are issued or at any time while the Corporation's
repurchase right remains outstanding, to provide for the automatic termination
of one or more of those outstanding rights and the immediate vesting of the
shares of Common Stock subject to such rights upon the occurrence of a Corporate
Transaction.

      C. 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 remain outstanding under the Stock Issuance
Program, to provide that those rights shall automatically terminate in whole or
in part, and the shares of Common Stock subject to those terminated rights shall
immediately vest, in the event the Participant's Service should 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).

      D. 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 remain outstanding under the Stock Issuance
Program, to provide that those rights shall automatically terminate in whole or
in part, and the shares of Common Stock subject to those terminated rights shall
immediately vest upon (i) a Change in Control or (ii) the termination of the
Participant's Service by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of such Change in Control.

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.

                                  ARTICLE FOUR

                         AUTOMATIC OPTION GRANT PROGRAM

I. OPTION TERMS

      A. Grant Dates. Option grants shall be made on the dates specified below:

            1. Each individual who is first elected or appointed as a
non-employee Board member at any time after the Plan Effective Date shall
automatically be granted, on the date of such initial election or appointment, a
Non-Statutory Option to purchase 20,000 shares of Common Stock, provided that
individual has not previously been a director of or in the employ of the
Corporation or any Parent or Subsidiary.

            2. On the date of the 1998 Annual Meeting (the Stockholder Approval
Date) and on the date of each Annual Stockholders Meeting held after such date,
each individual who is to continue to serve as an Eligible Director, whether or
not that individual is standing for re-election to the Board at that particular
Annual Meeting, shall automatically be granted a Non-Statutory Option to
purchase 10,000 shares of Common Stock, provided that such amount shall be
increased to 20,000 shares for grants on or after the date of the 2000 Annual
Meeting, with respect to each Annual Stockholders Meeting, such individual has

                                       10
<PAGE>

served as a non-employee board member for at least six (6) months. There shall
be no limit on the number of such 10,000 or 20,000-share option grants any one
Eligible Director may receive over his or her period of Board Service, and
non-employee board members who have previously been a director of or in the
employ of the Corporation (or any Parent or Subsidiary) shall be eligible to
receive one or more such annual option grants over their period of continued
Board Service.

      B. Exercise Price.

            1. The exercise price per share shall be equal to sixty percent
(60%) of the Fair Market Value per share of Common Stock on the option grant
date.

            2. The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

      C. Option Term. Each option shall have a term of ten (10) years measured
from the option grant date.

      D. Exercise and Vesting of Options. Each option shall be immediately
exercisable for any or all of the option shares. However, any shares purchased
under the option shall be subject to repurchase by the Corporation, at the
exercise price paid per share, upon the Optionee's cessation of Board Service
prior to vesting in those shares. With respect to options granted on or after
the date of the 1998 annual stockholders' meeting, each option shall vest, and
the Corporation's repurchase right shall lapse, on the first anniversary of the
date of grant.

      E. Termination of Board Service. The following provisions shall govern the
exercise of any options held by the Optionee at the time the Optionee ceases to
serve as a Board member:

                  (i) The Optionee (or, in the event of the Optionee's death,
      the personal representative of the Optionee's estate or the person or
      persons to whom the option is transferred pursuant to the Optionee's will
      or in accordance with the laws of descent and distribution) shall have a
      twelve (12)-month period following the date of such cessation of Board
      Service in which to exercise each such option.

                  (ii) During the twelve (12)-month post-service exercise
      period, the option may not be exercised in the aggregate for more than the
      number of vested shares of Common Stock for which the option is
      exercisable at the time of the Optionee's cessation of Board Service.

                  (iii) Should the Optionee cease to serve as a Board member by
      reason of death or Permanent Disability, then all shares at the time
      subject to the option shall immediately vest so that such option may,
      during the twelve (12)-month exercise period following such cessation of
      Board Service, be exercised for all or any portion of those shares as
      fully-vested shares of Common Stock.

                  (iv) In no event shall the option remain exercisable after the
      expiration of the option term. Upon the expiration of the twelve
      (12)-month post-service 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 Board Service for any reason other than death or Permanent
      Disability, terminate and cease to be outstanding to the extent the option
      is not otherwise at that time exercisable for vested shares.

II. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

      A. In the event of any Corporate Transaction, the shares of Common Stock
at the time subject to each outstanding option but not otherwise vested 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 such option and may be
exercised for all or any portion of those shares as fully-vested shares of
Common Stock. Immediately following the consummation of the Corporate
Transaction, each automatic option grant shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

                                       11
<PAGE>

      B. In connection with any Change in Control, the shares of Common Stock at
the time subject to each outstanding option but not otherwise vested shall
automatically vest in full so that each such option shall, immediately prior to
the effective date of the Change in Control, become fully exercisable for all of
the shares of Common Stock at the time subject to such option and may be
exercised for all or any portion of those shares as fully-vested shares of
Common Stock. Each such option shall remain exercisable for such fully-vested
option shares until the expiration or sooner termination of the option term or
the surrender of the option in connection with a Hostile Take-Over.

      C. Upon the occurrence of a Hostile Take-Over, the Optionee shall have a
thirty (30)-day period in which to surrender to the Corporation each of his or
her outstanding automatic option grants. The Optionee shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to each surrendered option (whether or not the Optionee is otherwise at
the time vested in those shares) over (ii) the aggregate exercise price payable
for such shares. Such cash distribution shall be paid within five (5) days
following the surrender of the option to the Corporation. No approval or consent
of the Board or any Plan Administrator shall be required in connection with such
option surrender and cash distribution.

      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 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 grant of options under the Automatic Option Grant Program 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.

III. REMAINING TERMS

      The remaining terms of each option granted under the Automatic Option
Grant Program shall be the same as the terms in effect for option grants made
under the Discretionary Option Grant Program.

                                  ARTICLE FIVE

                                  MISCELLANEOUS

I. FINANCING

      The Plan Administrator may permit any Optionee or Participant to pay the
option exercise price under the Discretionary Option Grant Program or the
purchase price of shares issued under the Stock Issuance Program by delivering a
full-recourse, interest bearing promissory note payable in one or more
installments. The terms of any such promissory note (including the interest rate
and the terms of repayment) shall be established by the Plan Administrator in
its sole discretion. In no event may 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 purchased shares plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee or
the Participant in connection with the option exercise or share purchase.

                                       12

II. TAX WITHHOLDING

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

      B. The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan (other than the options granted or the shares issued under the Automatic
Option Grant Program) with the right to use shares of Common Stock in
satisfaction of all or part of the Taxes incurred by such holders in connection
with the exercise of their options or the vesting of their shares. Such right
may be provided to any such holder in either or both of the following formats:

            Stock Withholding: The election to have the Corporation withhold,
from the shares of Common Stock otherwise issuable upon the exercise of such
Non-Statutory Option or the vesting of such shares, a portion of those shares
with an aggregate Fair Market Value equal to the percentage of the Taxes (not to
exceed one hundred percent (100%)) designated by the holder.

            Stock Delivery: The election to deliver to the Corporation, at the
time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Taxes) with
an aggregate Fair Market Value equal to the percentage of the Taxes (not to
exceed one hundred percent (100%)) designated by the holder.

III. EFFECTIVE DATE AND TERM OF THE PLAN

no options granted under the Plan may be exercised, and no shares shall be
issued under the Plan, until the Stockholder Approval Date. If the Stockholder
Approval Date does not occur within twelve (12) months after the Plan Effective
Date, then all options previously granted under this Plan shall terminate and
cease to be outstanding, and no further options shall be granted and no shares
shall be issued under the Plan.

      B. One or more provisions of the Plan, including (without limitation) the
option/vesting acceleration provisions of Article Two relating to Corporate
Transactions and Changes in Control, may, in the Plan Administrator's
discretion, be extended to one or more options incorporated from the Predecessor
Plan on the Stockholder Approval Date which do not otherwise contain such
provisions.

the date on which all shares available for issuance under the Plan shall have
been issued as fully-vested shares or (iii) the termination of all outstanding
options in connection with a Corporate Transaction. Upon such plan termination,
all outstanding option grants and unvested stock issuances shall thereafter
continue to have force and effect in accordance with the provisions of the
documents evidencing such grants or issuances.

IV. 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
stock 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 stockholder approval
pursuant to applicable laws or regulations.

      B. Options to purchase shares of Common Stock may be granted under the
Discretionary Option Grant Programs and shares of Common Stock may be issued
under the Stock Issuance Program that are in each instance in excess of the
number of shares 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 stockholder approval of an amendment sufficiently increasing the
number of shares of Common Stock available for issuance under the Plan.

                                       13
<PAGE>

If such stockholder 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.

V. 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.

VI. REGULATORY APPROVALS

      A. The implementation of the Plan, the granting of any stock option under
the Plan and the issuance of any shares of Common Stock (i) upon the exercise of
any granted option or (ii) under the Stock Issuance Program shall be subject to
the Corporation's procurement of all approvals and permits required by
regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.

      B. No shares of Common Stock or other assets shall be issued or delivered
under the Plan unless and until there shall have been compliance with all
applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.

VII. NO EMPLOYMENT/SERVICE RIGHTS

      Nothing in the Plan shall confer upon the Optionee or the Participant any
right to continue in Service or Board 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 or Board Service at any time for any
reason, with or without cause.
