                EMPLOYEE NONDISCLOSURE AND DEVELOPMENTS AGREEMENT
                -------------------------------------------------

In consideration and as a condition of my employment or continued employment by
NEON Systems, Inc. (the "Company"), I hereby agree with the Company as follows:

1. I will not at any time, whether during or after the termination of my
employment, reveal to any person or entity any of the trade secrets or
confidential information concerning the organization, business or finances of
the Company or of any third party which the Company is under an obligation to
keep confidential ( including but not limited to trade secrets or confidential
information respecting inventions, products, designs, methods, know-how,
techniques, systems, processes, software programs, works of authorship, customer
lists, projects, plans and proposals), except as may be required in the ordinary
course of performing my duties as an employee of the Company, and I shall keep
secret all matters entrusted to me and shall not use or attempt to use any such
information in any manner which may injure or cause loss or may be calculated to
injure or cause loss whether directly or indirectly to the Company.

Further, I agree that during my employment I shall not make, use or permit to be
used any notes, memoranda, reports, lists, records, drawings, sketches,
specifications, software programs, data, documentation or other materials of any
nature relating to concerning any of its dealings or affairs otherwise than for
the benefit of the Company. I further agree that I shall not, after the
termination of my employment, use or permit to be used any such notes,
memoranda, reports, lists, records, drawings, sketches, specifications, software
programs, data documentation or other materials, it being agreed that all of the
foregoing shall be and remain the sole and exclusive property of the Company and
that immediately upon the termination of my employment I shall deliver all of
the foregoing, and all copies thereof, to the Company, at its main office.

2. If at any time or times during my employment, I shall (either alone or with
others) make, conceive, discover or reduce to practice any invention,
modification, discovery, design, development, improvement, process, software
program, work of authorship, documentation, formula, data, technique, know-how,
secret or intellectual property right whatsoever or any interest therein
(whether or not patentable or registrable under copyright or similar statutes or
subject to analogous protection ) (herein called "Developments") that (a)
relates to the business of the Company or any customer of or supplier to the
Company or any of the products or services being developed, manufactured or sold
by the Company or which may be used in relation therewith, (b) results from
tasks assigned me by the company or (c) results from the use of premises or
personal property (whether tangible or intangible) owned, leased or contracted
for by the Company and its assigns, and I shall promptly disclose to the Company
(or any persons designated by it) each such Development and hereby assign any
rights I may have or acquire in the Developments and benefits without further
compensation and shall communicate, without cost or delay, and without
publishing the same, all available information relating thereto (with all
necessary plans and models) to the Company.

Upon disclosure of each Development to the Company, I will, during my employment
and at any time thereafter, at the request and cost of the Company, sign,
execute, make and do all such deeds, documents, acts and things as the Company
and its duly authorized agents may reasonably require:

(a) to apply for, obtain and vest in the name of the Company alone (unless the
Company otherwise directs) letters patent, copyrights or other analogous
protection in any country throughout the world and when so obtained or vested to
renew and restore the same; and

(b) to defend any opposition proceedings in respect of such applications and any
opposition proceedings or petitions or applications for revocation of such
letters patent, copyright or other analogous protection.

                                     Page 1

<PAGE>

In the event the Company is unable, after reasonable effort, to secure my
signature on any letters patent, copyright or other analogous protection
relating to a Development, whether because of my physical or mental incapacity
or for any other reason whatsoever, I hereby irrevocably designate and appoint
the Company and its duly authorized officers and agents as my agent and
attorney-in-fact, to act for and in my behalf and stead to execute and file any
such application or applications and to do all other lawfully permitted acts to
further the prosecution and issuance of letters patent, copyright or other
analogous protection thereon with the same legal force and effect as if executed
by me.

3. I agree that any breach of this Agreement by me will cause irreparable damage
to the Company and that in the event of such breach the Company shall have, in
addition to any and all remedies of law, the right to an injunction, specific
performance or other equitable relief to prevent the violation of my obligations
hereunder.

4. I understand that this Agreement does not create an obligation on the Company
or any other person or entity to continue my employment.

5. I represent that the Developments identified in the pages, if any, attached
hereto comprise all the unpatented and uncopyrighted Developments which I have
made or conceived prior to my employment by the Company, which Developments are
excluded from this Agreement. I understand that it is only necessary to list the
title and purpose of such Developments but not details thereof.

6. In order to provide for an expeditious resolution of any "Covered Dispute"
   (as such term is defined in paragraph (a) below), I agree to the mandatory
   mediation and arbitration procedure set forth below (the "Procedure"):

          (a) The term "Covered Dispute" shall mean and include, subject to
   paragraph (b) below, any dispute that may arise between the Company and me
   relating to my employment or any termination of my employment and any dispute
   that may arise between the Company and me relating to this Agreement. Subject
   to paragraph (b) below, "Covered Disputes" shall include, without limitation,
   (i) any dispute regarding the arbitrability of any matter hereunder and (ii)
   any claim that could be asserted in court or before an administrative agency
   or claims as to which I have an alleged cause of action, including without
   limitation claims for breach of any contract or covenant (express or
   implied), tort claims, claims for discrimination (including but not limited
   to discrimination based on sex, pregnancy, race, national or ethnic origin,
   age, religion, creed, marital status, sexual orientation, mental or physical
   disability or medical condition or other characteristics protected by
   statute), claims for wrongful discharge, violations of confidentiality or
   breaches of trade secrets, and/or claims for violation of any federal, state
   or other governmental law, statue, regulation or ordinance, and whether based
   on statute or common law. Covered Disputes include all such claims whether
   made against the Company, any of its subsidiary or affiliated entities, or
   the individual officers or directors thereof (in an official or personal
   capacity).

                                     Page 2

<PAGE>

          (b) Notwithstanding any other provision of this Section 6, the
   following claims shall not be "Covered Disputes" and shall not be subject to
   the Procedure: (i) claims for workers' compensation benefits; (ii) claims for
   unemployment compensation benefits; (iii) claims by the Company for
   injunctive and/or other equitable relief, including but not limited to such
   claims for unfair competition and/or the use or unauthorized disclosure of
   trade secrets or confidential information, as to which the Company may seek
   and obtain relief from a court of competent jurisdiction; and (iv) a claim
   based upon the Company's current, successor or future employee benefits
   and/or welfare plans that contain an appeal procedure or other procedure for
   the resolution of disputes under the Plan.

          (c) Under the Procedure, Covered Disputes must (after appropriate
   attempts to resolve the dispute internally through the Company's management)
   be submitted for resolution by non-binding mediation and, if needed,
   mandatory arbitration.

          (d) I acknowledge that my agreement to the Procedure is given in
   exchange for rights to which I am not otherwise entitled - namely, the more
   expeditious resolution of disputes, my employment or continued employment by
   the Company, and my being provided access to confidential information and
   trade secrets of the company, whether now or hereafter existing or developed,
   as may be required or permitted by the Company in the ordinary course of
   performing my duties as an employee of the Company. In exchange for my
   agreement to the Procedure, the Company likewise is agreeing to the use of
   mediation and arbitration as the exclusive forum for resolving Covered
   Disputes. Therefore, both the Company and I shall be precluded from bringing
   or raising in court or another forum any Covered Dispute.

          (e) I agree with the Company that any Covered Dispute must be
   submitted for non-binding mediation before a neutral third party and (if
   necessary) for final and binding resolution by a private and impartial
   arbitrator, to be jointly selected by the Company and me.

          (f) As a prerequisite for submitting a Covered Dispute to mediation
   and (if necessary) arbitration, I agree to make good-faith efforts to resolve
   the Covered Dispute internally on an informal basis through the Company's
   management channels appropriate to the circumstances of that individual
   dispute. All disputes shall initially be referred to the President of the
   Company. Only when such internal efforts fail my I submit an employment
   dispute to mediation and (if necessary) final and binding arbitration under
   the terms of the Procedure.

          (g) If efforts at informal resolution fail, I agree that Covered
   Disputes must first be submitted for non-binding mediation before a neutral
   third party. Mediation is an informal process where the parties to a dispute
   meet in an attempt to reach a voluntary resolution, using the third party as
   a facilitator. Mediation shall be conducted and administered by the American
   Arbitration Association ("AAA") under its Employment Mediation Rules, which
   are incorporated herein by reference.

          (h) If a Covered Dispute remains unresolved at the conclusion of the
   mediation process, I agree that either I or the Company may submit the
   dispute for resolution by final binding arbitration under the Procedure. The
   arbitration will be conducted under the Employment Dispute Resolution Rules
   of the AAA, as amended and effective on June 1, 1996, and as such Rules may
   be amended from time to time after the date hereof. These Rules, incorporated
   by reference herein, include (but are not limited to) the procedures for the
   joint selection of an impartial arbitrator and for the hearing of evidence
   before the arbitrator. The arbitrator shall have the authority to allow for
   appropriate discovery and exchange of information prior to a hearing,
   including (but not limited to) production of documents, information requests,
   depositions and subpoenas. I acknowledge that I may obtain a copy of the
   complete AAA Employment Dispute Resolution Rules from the Business Manager.

<PAGE>

          (i) I agree that any conflict between the rules and procedures set
   forth in the AAA Rules and those set forth in this Agreement shall be
   resolved in favor of those in this Agreement. The burden of proof at an
   arbitration shall at all times be upon the party seeking relief. In reaching
   his or her decision, the arbitrator shall apply the governing substantive law
   applicable to the claim(s), cause(s) of action and defense(s) asserted by the
   parties as applicable in the State of Texas or other applicable jurisdiction.
   The arbitrator shall have the power to award all remedies that could be
   awarded by a court or administrative agency in accordance with the governing
   and applicable substantive law.

          (j) I agree that, with respect to any Covered Dispute, the aggrieved
   party must give written notice of any claim to the other party within three
   months of the date the aggrieved first knew or should have known of the facts
   giving rise to the claim; otherwise, the claim shall be void and deemed
   waived. The written notice shall describe the nature of all claims asserted
   and the facts upon which such claims are based and shall be mailed to the
   other party by certified or registered mail, return receipt requested. Any
   such notice mailed to the Company shall be addressed to the President of the
   Company.

          (k) Any mediation or arbitration conducted pursuant to the Procedure
   shall take place in Sugar Land, Texas unless an alternative location is
   chosen by the mutual agreement of the parties. The arbitrator shall render a
   decision and award within 30 days after the close of arbitration hearing or
   at any later time on which the parties may agree. The award shall be in
   writing and signed and dated by the arbitrator and shall contain express
   findings of fact and the basis for the award.

          (l) I agree the Company and I will share equally the AAA
   administrative fees and the fees and expenses of any and all mediators and
   arbitrators. All other costs and expenses associated with the arbitration,
   including, without limitation, the parties' respective attorneys fees, shall
   be borne by the party incurring the expense.

          (m) Judgment upon the award rendered by the arbitrator may be entered
   in any court having jurisdiction. The award may be vacated or modified only
   on the grounds specified in the U.S. Arbitration Act or other applicable law.

          I further agree that the Procedure does not in any way alter my status
   as an at-will employee of the Company. Accordingly, I acknowledge that I am,
   and the Company is, always free to terminate the employment relationship at
   any time for any lawful reason (with or without cause), and my employment is
   not for any specific or definite duration.

   7. Any waiver by the Company of a breach of any provision of this Agreement
   shall not operate or be construed as a waiver of any subsequent breach of
   such provision or any other provision hereof.

   8. I hereby agree that each provision herein shall be treated as a separate
   and independent clause, and the unenforceability of any one clause shall in
   no way impair the enforceability of any of the other clauses herein.
   Moreover, if one or more of the provisions contained in this Agreement shall
   for any reason be held to be excessively broad as to scope, activity, subject
   or otherwise so as to be unenforceable at law, such provision or provisions
   shall be construed by the appropriate judicial body by limiting or reducing
   it or them, so as to be enforceable to the maximum extent compatible with the
   applicable law as it shall then appear.

   9. My obligations under this Agreement shall survive the termination of my
   employment regardless of the manner of such termination and shall be binding
   upon my heirs, executors, administrators and legal representatives.

   10. The term "Company" shall include NEON Systems, Inc. and any of its
   subsidiaries, subdivisions or affiliates. The Company shall have the right to
   assign this Agreement to its successors and assigns, and all covenants and
   agreements hereunder shall inure to the benefit of and be enforceable by said
   successors or assigns.

   11. This Agreement shall be governed by and construed in accordance with the
   laws of Texas.

Stock pursuant to Section 11 of the Plan, as evidenced by a Notice of Grant.

             (ee)      "Subsidiary" means a "subsidiary corporation," whether
                        ----------
now or hereafter existing, as defined in Section 424(f) of the Code.

     3.      Stock Subject to the Plan. Subject to the provisions of Section 13
             -------------------------
of the Plan, the maximum aggregate number of Shares that may be sold under the
Plan is 2,000,000 Shares plus (a) any Shares which have been reserved but not
issued under the Company's 1999 Long-Term Incentive Plan (the "1999 Plan") as of
the date of stockholder approval of this Plan, (b) any Shares returned to the
1999 Plan as a result of termination of options or repurchase of Shares issued
under the 1999 Plan and (c) an annual increase to be added on the first day of
the Company's fiscal year beginning April 1, 2003, equal to the lesser of (i)
750,000 Shares, (ii) 5% of the outstanding Shares on such date or (iii) an
amount determined by the Board. The Shares may be authorized, but unissued, or
reacquired Common Stock.

             If an Option or Stock Purchase Right expires or becomes
unexercisable without having been exercised in full, or is surrendered pursuant
to an Option Exchange Program, the unpurchased Shares which were subject thereto
shall become available for future grant or sale under the Plan (unless the Plan
has terminated); provided, however, that Shares that have actually been issued
under the Plan, whether upon exercise of an Option or Stock Purchase Right,
shall not be returned to the Plan and shall not become available for future
distribution under the Plan, except that if Shares of Restricted Stock are
repurchased by the Company at their original purchase price, such Shares shall
become available for future grant under the Plan.

     4.      Administration of the Plan.
             --------------------------
             (a)       Procedure.
                       ---------
                        (i)     Multiple Administrative Bodies. Different
                                ------------------------------
Committees with respect to different groups of Employees may administer the
Plan.

                       (ii)     Section 162(m). To the extent that the
                                --------------
Administrator determines it to be desirable to qualify Options granted hereunder
as "performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administered by a Committee of two or more "outside
directors" within the meaning of Section 162(m) of the Code.

                      (iii)     Rule 16b-3. To the extent desirable to qualify
                                ----------
transactions hereunder as exempt under Rule 16b-3, the transactions contemplated
hereunder shall be structured to satisfy the requirements for exemption under
Rule 16b-3, including having the Plan administered by a Committee comprised
solely of "Non-Employee Directors" within the meaning of Rule 16b-3(b)(3).

                       (iv)     Other Administration. Other than as provided
                                --------------------
above, the Plan shall be administered by (A) the Board or (B) a Committee, which
committee shall be constituted to satisfy Applicable Laws.

             (b)       Powers of the Administrator. Subject to the provisions of
                       ---------------------------
the Plan, and in the case of a Committee, subject to the specific duties
delegated by the Board to such Committee, the Administrator shall have the
authority, in its discretion:

                       (i)     to determine the Fair Market Value;

                      (ii)     to select the Employees to whom Options and Stock
Purchase Rights may be granted hereunder;

                     (iii)     to determine the number of shares of Common
Stock to be covered by each Option and Stock Purchase Right granted hereunder;

                      (iv)     to approve forms of agreement for use under the
Plan;

                       (v)     to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any Option or Stock Purchase Right
granted hereunder. Such terms and conditions include, but are not limited to,
the exercise price, the time or times when Options or Stock Purchase Rights may
be exercised (which may be based on performance criteria), any vesting
acceleration or waiver of forfeiture restrictions, and any restriction or
limitation regarding any Option or Stock Purchase Right or the shares of Common
Stock relating thereto, based in each case on such factors as the Administrator,
in its sole discretion, shall determine;

                      (vi)     to reduce the exercise price of any Option or
Stock Purchase Right to the then current Fair Market Value if the Fair Market
Value of the Common Stock covered by such Option or Stock Purchase Right shall
have declined since the date the Option or Stock Purchase Right was granted;

                     (vii)     to institute an Option Exchange Program;

                    (viii)     to construe and interpret the terms of the Plan
and awards granted pursuant to the Plan;

                      (ix)     to establish, amend and rescind rules and
regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of satisfying applicable foreign laws;

                                      -4-

<PAGE>

                       (x)     to modify or amend each Option or Stock Purchase
Right (subject to Section 15(c) of the Plan), including the discretionary
authority to extend the post-termination exercisability period of Options longer
than is otherwise provided for in the Plan;

                      (xi)     to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option or Stock Purchase Right that number of Shares
having a Fair Market Value equal to the minimum amount required to be withheld.
The Fair Market Value of the Shares to be withheld shall be determined on the
date that the amount of tax to be withheld is to be determined. All elections by
an Optionee to have Shares withheld for this purpose shall be made in such form
and under such conditions as the Administrator may deem necessary or advisable;

                     (xii)     to authorize any person to execute on behalf of
the Company any instrument required to effect the grant of an Option or Stock
Purchase Right previously granted by the Administrator;

                    (xiii)     to correct any defect, supply any omission, or
reconcile any inconsistency in the Plan, or in any Option Agreement, in a manner
and to the extent it shall deem necessary, all of which determinations and
interpretations made by the Administrator shall be conclusive and binding on all
Optionees, any other holders of Options and on their legal representatives and
beneficiaries;

                     (xiv)     except to the extent prohibited by, or
impermissible in order to obtain treatment desired by the Administrator under,
applicable law or rule, to allocate or delegate all or any portion of its powers
and responsibilities to any one or more of its members or to any person(s)
selected by it, subject to revocation or modification by the Administrator of
such allocation or delegation; and

                      (xv)     to make all other determinations deemed
necessary or advisable for administering the Plan.

             (c)       Effect of Administrator's Decision. The Administrator's
                       ----------------------------------
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options or Stock Purchase Rights.

     5.      Eligibility. Incentive Stock Options, Nonstatutory Stock Options
             -----------
and Stock Purchase Rights may only be granted to Employees.

     6.      Limitations.
             -----------
             (a)       Each Option shall be designated in the Option Agreement
as either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

             (b)       Neither the Plan nor any Option or Stock Purchase Right
shall confer upon an Optionee any right with respect to continuing the
Optionee's relationship as an Employee with the Company, nor shall they
interfere in any way with the Optionee's right or the Company's right to
terminate such relationship at any time, with or without cause.

             (c)       The following limitations shall apply to grants of
Options:

                         (i)    No Employee shall be granted, in any fiscal year
of the Company, Options to purchase more than 500,000 Shares.

                        (ii)    The foregoing limitation shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 13.

                                      -5-

<PAGE>

                       (iii)    If an Option is cancelled in the same fiscal
year of the Company in which it was granted (other than in connection with a
transaction described in Section 13), the cancelled Option will be counted
against the limit set forth in subsection (i) above. For this purpose, if the
exercise price of an Option is reduced, the transaction will be treated as a
cancellation of the Option and the grant of a new Option.

     7.      Term of Plan. Subject to Section 19 of the Plan, the Plan shall
             ------------
become effective upon its adoption by the Board. It shall continue in effect for
a term of ten (10) years unless terminated earlier under Section 15 of the Plan.

     8.      Term of Option. The term of each Option shall be stated in the
             --------------
Option Agreement. In the case of an Incentive Stock Option, the term shall be
ten (10) years from the date of grant or such shorter term as may be provided in
the Option Agreement. Moreover, in the case of an Incentive Stock Option granted
to an Optionee who, at the time the Incentive Stock Option is granted, owns
stock representing more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
term of the Incentive Stock Option shall be five (5) years from the date of
grant or such shorter term as may be provided in the Option Agreement.

     9.      Option Exercise Price and Consideration.
             ---------------------------------------

             (a)       Exercise Price. The per share exercise price for the
                       --------------
Shares to be issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

                         (i)    In the case of an Incentive Stock Option

                                (A)    granted to an Employee who, at the time
the Incentive Stock Option is granted, owns stock representing more than ten
percent (10%) of the voting power of all classes of stock of the Company or any
Parent or Subsidiary, the per Share exercise price shall be no less than 110% of
the Fair Market Value per Share on the date of grant.

                                (B)    granted to any Employee other than an
Employee described in paragraph (A) immediately above, the per Share exercise
price shall be no less than 100% of the Fair Market Value per Share on the date
of grant.

                        (ii)    In the case of a Nonstatutory Stock Option, the
per Share exercise price shall be determined by the Administrator. In the case
of a Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                       (iii)    Notwithstanding the foregoing, Options may be
granted with a per Share exercise price of less than 100% of the Fair Market
Value per Share on the date of grant pursuant to a merger or other corporate
transaction.

             (b)       Waiting Period and Exercise Dates. At the time an Option
                       ---------------------------------
is granted, the Administrator shall fix the period within which the Option may
be exercised and shall determine any conditions that must be satisfied before
the Option may be exercised.

             (c)       Form of Consideration. The Administrator shall determine
                       ---------------------
the acceptable form of consideration for exercising an Option, including the
method of payment. In the case of an Incentive Stock Option, the Administrator
shall determine the acceptable form of consideration at the time of grant. Such
consideration may consist entirely of:

                         (i)    cash;

                        (ii)    check;

                       (iii)    promissory note;

                                      -6-

<PAGE>

                        (iv)    other Shares, provided such Shares (A) if
acquired directly or indirectly from the Company, have been owned by the
Optionee for more than six (6) months on the date of surrender, and (B) have a
Fair Market Value on the date of surrender equal to the aggregate exercise price
of the Shares as to which said Option shall be exercised;

                         (v)    consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the
Plan;

                        (vi)    a reduction in the amount of any Company
liability to the Optionee, including any liability attributable to the
Optionee's participation in any Company-sponsored deferred compensation program
or arrangement;

                       (vii)    such other consideration and method of payment
for the issuance of Shares to the extent permitted by Applicable Laws; or

                      (viii)    any combination of the foregoing methods of
payment.

     10.     Exercise of Option.
             ------------------

             (a)       Procedure for Exercise; Rights as a Stockholder. Any
                       -----------------------------------------------
Option granted hereunder shall be exercisable according to the terms of the Plan
and at such times and under such conditions as determined by the Administrator
and set forth in the Option Agreement. Unless the Administrator provides
otherwise, vesting of Options granted hereunder shall be suspended during any
unpaid leave of absence. An Option may not be exercised for a fraction of a
Share.

                       An Option shall be deemed exercised when the Company
receives: (i) written or electronic notice of exercise (in accordance with the
Option Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised and any
withholding taxes the Company is required to withhold or arrangements for the
payment of such taxes, satisfactory to the Company, have been made. Full payment
may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse or
in the name of a family trust of which the Optionee is a trustee. Until the
Shares are issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a stockholder shall exist with
respect to the Optioned Stock, notwithstanding the exercise of the Option. The
Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised; provided that if the Company shall be advised by counsel
that certain requirements under the Federal, state or foreign securities laws
must be met before Shares may be issued under this Plan, the Company shall
notify all persons who have been issued Options, and the Company shall have no
liability for failure to issue Shares under any exercise of Options because of
delay while such requirements are being met or the inability of the Company to
comply with such requirements. No adjustment will be made for a dividend or
other right for which the record date is prior to the date the Shares are
issued, except as provided in Section 13 of the Plan.

                       Exercising an Option in any manner shall decrease the
number of Shares thereafter available, both for purposes of the Plan and for
sale under the Option, by the number of Shares as to which the Option is
exercised.

             (b)       Termination of Relationship as an Employee. If an
                       ------------------------------------------
Optionee ceases to be an Employee, other than upon the Optionee's death or
Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination (but in no event later
than the expiration of the term of such Option as set forth in the Option
Agreement). If, on the date of termination, the Optionee is not vested as to his
or her entire Option, the Shares covered by the unvested portion of the Option
shall revert to the Plan. If, after termination, the Optionee does not exercise
his or her

                                      -7-

<PAGE>

Option within the time specified herein, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

             (c)       Disability of Optionee. If an Optionee ceases to be an
                       ----------------------
Employee as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option Agreement
to the extent the Option is vested on the date of termination (but in no event
later than the expiration of the term of such Option as set forth in the Option
Agreement). In the absence of a specified time in the Option Agreement, the
Option shall remain exercisable for twelve (12) months following the Optionee's
termination (but in no event later than the expiration of the term of such
Option as set forth in the Option Agreement). If, on the date of termination,
the Optionee is not vested as to his or her entire Option, the Shares covered by
the unvested portion of the Option shall revert to the Plan. If, after
termination, the Optionee does not exercise his or her Option within the time
specified herein, the Option shall terminate, and the Shares covered by such
Option shall revert to the Plan.

             (d)       Death of Optionee. If an Optionee dies, the Option may be
                       -----------------
exercised following the Optionee's death within such period of time as is
specified in the Option Agreement to the extent that the Option is vested on the
date of death (but in no event may the Option be exercised later than the
expiration of the term of such Option as set forth in the Option Agreement), by
the Optionee's designated beneficiary, provided such beneficiary has been
designated prior to the Optionee's death in a form acceptable to the
Administrator. If no such beneficiary has been designated by the Optionee, then
such Option may be exercised by the personal representative of the Optionee's
estate or by the person(s) to whom the Option is transferred pursuant to the
Optionee's will or in accordance with the laws of descent and distribution. In
the absence of a specified time in the Option Agreement, the Option shall remain
exercisable for twelve (12) months following the Optionee's death (but in no
event later than the expiration of the term of such Option as set forth in the
Option Agreement). If, at the time of death, the Optionee is not vested as to
his or her entire Option, the Shares covered by the unvested portion of the
Option shall immediately revert to the Plan. If the Option is not so exercised
within the time specified herein, the Option shall terminate, and the Shares
covered by such Option shall revert to the Plan.

     11.     Stock Purchase Rights.
             ---------------------

             (a)       Rights to Purchase. Stock Purchase Rights may be issued
                       ------------------
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan. After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing or electronically, by means of a Notice of Grant,
of the terms, conditions and restrictions related to the offer, including the
number of Shares that the offeree shall be entitled to purchase, the price to be
paid, and the time within which the offeree must accept such offer. The offer
shall be accepted by execution of a Restricted Stock Purchase Agreement in the
form determined by the Administrator.

             (b)       Repurchase Option. Unless the Administrator determines
                       -----------------
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's employment with the Company, its Parent and Subsidiaries for any
reason (including death or Disability). The purchase price for Shares
repurchased pursuant to the Restricted Stock Purchase Agreement shall be the
original price paid by the purchaser and may be paid by cancellation of any
indebtedness of the purchaser to the Company. The repurchase option shall lapse
at a rate determined by the Administrator.

             (c)       Other Provisions. The Restricted Stock Purchase Agreement
                       ----------------
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion,
including tax withholding rights and obligations.

             (d)       Rights as a Stockholder. Once the Stock Purchase Right is
                       -----------------------
exercised, the purchaser shall have the rights equivalent to those of a
stockholder, and shall be a stockholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 13
of the Plan.

     12.     Transferability of Options and Stock Purchase Rights. Unless
             ----------------------------------------------------
determined otherwise by the Administrator with respect to Nonstatutory Stock
Options, an Option or Stock Purchase Right may not be sold, pledged,

                                      -8-

<PAGE>

assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee. If the Administrator makes an
Option or Stock Purchase Right transferable, such Option or Stock Purchase Right
shall contain such additional terms and conditions as the Administrator deems
appropriate.

     13.     Adjustments Upon Changes in Capitalization, Dissolution, Merger or
             ------------------------------------------------------------------
Change in Control.
-----------------

             (a)       Changes in Capitalization. Subject to any required action
                       -------------------------
by the stockholders of the Company, the number of shares of Common Stock that
have been authorized for issuance under the Plan but as to which no Options or
Stock Purchase Rights have yet been granted or which have been returned to the
Plan upon cancellation or expiration of an Option or Stock Purchase Right, the
number of Shares that may be added annually to the Shares reserved under the
Plan (pursuant to Section 3(c)(i)) and the number of Shares as well as the price
per share of Common Stock covered by each such outstanding Option or Stock
Purchase Right, shall be proportionately adjusted for any increase or decrease
in the number of issued shares of Common Stock resulting from a stock split,
reverse stock split, stock dividend, combination or reclassification of the
Common Stock, or any other increase or decrease in the number of issued shares
of Common Stock effected without receipt of consideration by the Company;
provided, however, that conversion of any convertible securities of the Company
shall not be deemed to have been "effected without receipt of consideration."
Such adjustment shall be made by the Board, whose determination in that respect
shall be final, binding and conclusive. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
of Common Stock subject to an Option or Stock Purchase Right.

             (b)       Dissolution or Liquidation. In the event of the proposed
                       --------------------------
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option or Stock Purchase Right shall lapse
as to all such Shares, provided the proposed dissolution or liquidation takes
place at the time and in the manner contemplated. To the extent it has not been
previously exercised, an Option or Stock Purchase Right will terminate
immediately prior to the consummation of such proposed action.

             (c)       Merger or Change in Control. In the event of a merger of
                       ---------------------------
the Company with or into another corporation, or a Change in Control, each
outstanding Option and Stock Purchase Right shall be assumed or an equivalent
option or right substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the Option or Stock Purchase
Right, the Optionee shall fully vest in and have the right to exercise the
Option or Stock Purchase Right as to all of the Optioned Stock, including Shares
as to which it would not otherwise be vested or exercisable. If an Option or
Stock Purchase Right becomes fully vested and exercisable in lieu of assumption
or substitution in the event of a merger or Change in Control, the Administrator
shall notify the Optionee in writing or electronically that the Option or Stock
Purchase Right shall be fully vested and exercisable for a period of fifteen
(15) days from the date of such notice, and the Option or Stock Purchase Right
shall terminate upon the expiration of such period.

                       For the purposes of this subsection (c), the Option or
Stock Purchase Right shall be considered assumed if, following the merger or
Change in Control, the option or right confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option or Stock Purchase Right
immediately prior to the merger or Change in Control, the consideration (whether
stock, cash, or other securities or property) received in the merger or Change
in Control by holders of Common Stock for each Share held on the effective date
of the transaction (and if holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the merger or
Change in Control is not solely common stock of the successor corporation or its
Parent, the Administrator may, with the consent of the successor corporation,
provide for the consideration to be received upon the exercise of the Option or
Stock Purchase Right, for each Share of Optioned Stock subject to the Option or
Stock Purchase Right, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or Change in Control.

date as is determined by the Administrator. Notice of the determination shall

stockholder approval of any Plan amendment to the extent necessary and desirable
to comply with Applicable Laws.

             (c)       Effect of Amendment or Termination. No amendment,
                       ----------------------------------
alteration, suspension or termination of the Plan shall impair the rights of any
Optionee, unless mutually agreed otherwise between the Optionee and the
Administrator, which agreement must be in writing and signed by the Optionee and
the Company. Termination of the Plan shall not affect the Administrator's or
the Company's ability to exercise the powers granted to it hereunder with
respect to Options and Stock Purchase Rights granted under the Plan prior to the
date of such termination.

     16.     Conditions Upon Issuance of Shares.
             ----------------------------------

                       ----------------
the exercise of an Option or Stock Purchase Right unless the exercise of such
Option or Stock Purchase Right and the issuance and delivery of such Shares
shall comply with Applicable Laws and shall be further subject to the approval
of counsel for the Company with respect to such compliance.

                       --------------------------
exercise of an Option or Stock Purchase Right, the Company may require the
person exercising such Option or Stock Purchase Right to represent and warrant

investment and without any present intention to sell or distribute such Shares
if, in the opinion of counsel for the Company, such a representation is
required.

     17.     Inability to Obtain Authority. The inability of the Company to
             -----------------------------
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite
authority shall not have been obtained.

     18.     Reservation of Shares. The Company, during the term of this Plan,
             ---------------------
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

     19.     Stockholder Approval. The Plan shall be subject to approval by the
             --------------------
stockholders of the Company within twelve (12) months after the date the Plan is
adopted. Such stockholder approval shall be obtained in the manner and to the
degree required under Applicable Laws. No Option shall become exercisable or
Stock Purchase Right vested prior to such stockholder approval and in the event
such stockholder approval is not obtained, all awards granted under the Plan
shall be automatically cancelled.
