                                                 Form To Be Used For Option Plan
                                                 -------------------------------
                                                                   For Employees
                                                                   -------------

                             STOCK OPTION AGREEMENT

          THIS AGREEMENT, dated as of              , is made by and between
                                      -------------
RoTech Healthcare Inc., a Delaware corporation (the "Company"), and
                (the "Optionee").
---------------

          WHEREAS, the Optionee has been selected by the Board of Directors of
the Company (the "Board") or a committee thereof (including any compensation
committee created by the Board) to receive a grant of stock options under the
RoTech Healthcare Inc. Common Stock Option Plan (the "Plan").

          NOW, THEREFORE, in consideration of the Optionee's employment with the
Company, the Company and the Optionee agree as follows:

     1.   Definitions.
          -----------

          Any capitalized term not defined herein shall have the meaning set
forth in the Plan.

     2.   Grant of Option.
          ---------------

          (a) Grant: Grant Date. Subject to the terms and conditions hereof, the
              -----------------
Company hereby grants to the Optionee as of              (the "Grant Date") an
                                            ------------
option to purchase up to            Shares of the Company's common stock at an
                         ----------
exercise price of $               per Share.
                   --------------

          (b) Adjustments in Option. In the event that the outstanding Shares
              ---------------------
subject to the Option are changed into or exchanged for a different number or
kind of shares or securities of the Company, or of another corporation, by
reason of reorganization merger or other subdivision, consolidation,
recapitalization, reclassification, stock split, issuance of warrants, stock
dividend or combination of shares or similar event, the Board shall make an
appropriate and equitable adjustment in the Option so that the Optionee's
proportionate interest shall be maintained as before the occurrence of such
event, provided that any such adjustment shall be consistent with the provisions
of the Optionee's employment agreement, if applicable.

          (c) Form of Option. [Board must determine whether options are to be
              --------------
Incentive Stock Options, Nonqualified Stock Options, or a combination thereof,
and this provision must so state.]

          (d) Term. The Option shall expire on the tenth anniversary of the
              ----
Grant Date, or such earlier time as provided in Section 2(g) of this Agreement.
[If grant is an Incentive Stock Option to a Ten Percent Shareholder, the Option
shall expire on the fifth anniversary of the Grant Date or such earlier time as
provided in Section 2(g) of this Agreement.]

<PAGE>

          (e) Vesting. (i) The Option shall become vested and exercisable with
              -------
respect to one-quarter (25%) of the original aggregate number of Shares
purchasable upon exercise of such Option on each of the first four anniversaries
of the Grant Date, so that the Optionee shall be fully vested on the fourth
anniversary of the Grant Date. (ii) In the event of a Change in Control,
Optionee will be deemed to have become vested automatically in one-half (50%) to
one hundred percent (100%) of the Shares, such percentage to be determined in
the sole discretion of the Board. (iii) In the event of consummation of an
Initial Public Offering, one-quarter (25%) of the original aggregate number of
Shares purchasable upon exercise of such Option will be deemed to have vested.
(For purposes of illustration, assuming a Participant were granted at the
beginning of Year 1 an Option to purchase one hundred thousand (100,000) Shares
and at the end of Year 2 the Company were to consummate an Initial Public
Offering, such Option would vest and become exercisable as follows: (x)
twenty-five thousand (25,000) Shares at the end of Year 1, (y) twenty-five
thousand (25,000) Shares at the end of Year 2 (each as provided in clause (i)
above) and (z) an additional twenty-five thousand (25,000) Shares in Year 2 (as
provided in clause (iii) above). The remaining twenty-five thousand (25,000)
Shares would vest and become exercisable at the end of Year 3 (as provided in
clause (i) above).)

          (f) Exercise. The Optionee may exercise an Option in whole or in part
              --------
at any time by delivering written notice of such exercise to the Secretary of
the Company specifying the number of Shares as to which the Option is being
exercised, and enclosing payment for the aggregate exercise price of the Shares
with respect to which the Option is being exercised. Such payment shall be made
(i) in cash or by check, (ii) if approved by the Board, by the delivery of
Shares previously owned by the Optionee for at least six (6) months prior to
such exercise, duly endorsed for transfer to the Company, with a Fair Market
Value on the date of delivery equal to the aggregate exercise price of the
Shares with respect to which the Option is being exercised, (iii) by directing
the Company to subtract from the number of Shares underlying the Option, that
number of Shares having a Fair Market Value equal to the exercise price (or
portion thereof) required to be paid, or (iv) solely at a time when the Shares
are publicly-traded, pursuant to a "cashless exercise" of the Option pursuant to
the establishment of procedures whereby the Participant, by a properly executed
written notice, directs (A) an immediate market sale or margin loan respecting
all or a part of the Shares to which he is entitled upon exercise pursuant to an
extension of credit by the Company to the Participant, (B) the delivery of the
Shares from the Company directly to a brokerage firm and (C) the delivery of the
exercise price from sale or margin loan proceeds from the brokerage firm
directly to the Company, or (v) any combination of the foregoing approved by the
Board, in its sole discretion. Partial exercise shall be for whole Shares only
and shall not be for less than one hundred (100) Shares unless the number of
Shares purchased constitutes the total number of Shares then remaining subject
to the Option or the Board permits such smaller exercise in its sole discretion.

          (g) Exercise Following Termination of Employment. In the event the
              --------------------------------------------
Optionee's termination of employment is for Cause, the Option, whether
exercisable or nonexercisable, at such time, shall be deemed to have terminated
as of the day preceding such termination of employment. If such termination of
employment is for any reason other than Cause, any outstanding portion of the
Option that has not become exercisable shall terminate on the date of such
termination of employment, unless provided otherwise by the Board, in its sole
discretion. Any outstanding exercisable portion of an Option shall be
exercisable for the following periods:

                                     -2-

<PAGE>

               (A) If the Optionee's termination of employment is due to death,
retirement on or after age 65, or Disability, such exercisable portion of such
Option shall remain exercisable for its term, and shall thereafter terminate and
be of no further force or effect. Any Options that are not exercisable at such
time shall be of no further force or effect.

               (B) In all other cases, the Option shall be exercisable for
[      ] days following such termination of employment.

          (h) Nontransferability. The Option shall not be transferable other
              ------------------
than by will or the laws of descent and distribution, and no transfer so
effected shall be effective to bind the Company unless the Company has been
furnished with written notice thereof and a copy of the will and/or such other
evidence as the Board may deem necessary to establish the validity of the
transfer and the acceptance by the transferee or transferees of the terms and
conditions of the Option; provided, however, that, in the discretion of the
Board, Options may be transferred pursuant to a Qualified Domestic Relations
Order (within the meaning of the Code). [In addition, an Optionee may transfer
Options that are not Incentive Stock Options to his or her Immediate Family
Members.]

          (i) Conditions to Issuance of Stock Certificates.
              --------------------------------------------

               (1) The Shares deliverable upon the exercise of the Option, or
any portion thereof, may be either previously authorized but unissued Shares or
issued Shares which have been reacquired by the Company. Such Shares shall be
fully paid and non-assessable. The stock certificates evidencing the Shares
shall bear such legends restricting transferability as the Board deems necessary
or advisable.

               (2) The Company shall not be required to issue or deliver any
certificate or certificates for Shares deliverable upon any exercise of the
Option prior to fulfillment of all of the following conditions:

               (A) The completion of any registration or other qualification of
such Shares under any state or federal law or under rulings or regulations of
the Securities and Exchange Commission or of any other governmental regulatory
body, or the obtaining of approval or other clearance from any state or federal
governmental agency which the Board shall, in its sole discretion, deem
necessary or advisable.

               (B) If, in its sole discretion, the Board deems it necessary or
advisable, the execution by the Optionee of a written representation and
agreement, in a form satisfactory to the Board, in which the Optionee represents
that the Shares acquired by the Optionee upon exercise are being acquired for
investment and not with a view toward distribution thereof.

          (j) Rights as Stockholder. The Optionee shall not be, nor have any of
              ---------------------
the rights or privileges of, a stockholder of the Company in respect of any
Shares purchasable upon the exercise of the Option unless and until certificates
representing such Shares have been issued by the Company.

     3.   Miscellaneous.
          -------------

interpret or revoke any such rules. All actions taken and all interpretations
and determinations made by the Board shall be final and binding upon the
Optionee, the Company, and all other interested persons.

          (b) Withholding of Taxes. No later than the date as of which an amount
              --------------------
first becomes includible in the gross income of the Optionee for federal income
tax purposes with respect to an Option granted under this Agreement, the
Optionee shall pay to the Company, or the Optionee (or his designated
beneficiary) shall make arrangements satisfactory to the Company regarding the
payment of, any federal, estate, or local taxes of any kind required by law or
the Company to be withheld with respect to such amount. The obligations of the
Company under this Agreement shall be conditioned on such payment or
arrangements, and the Company shall, to the extent permitted by law, have the
right to deduct any such taxes from any payment of any kind otherwise due to the
Optionee.

          (c) No Right to Continued Employment. Nothing in this Agreement or in
              --------------------------------
the Plan shall confer upon the Optionee any right to continue in the employ of
the Company or shall interfere with or restrict in any way the rights of the
Company, which are hereby expressly reserved, to discharge the Optionee at any
time for any reason whatsoever, with or without Cause.

          (d) Entire Agreement; Amendment. This Agreement, and the Plan,
              ---------------------------

                              PATRON SYSTEMS, INC.
                             STOCK OPTION AGREEMENT

specifying the number of whole shares of Stock to be purchased and by
accompanying such notice with payment therefor in full (or by arranging for such
payment to the Company's satisfaction) (i) in cash or (ii) if the Stock has been
registered under the Securities Act and is publicly traded, (A) in cash, (B) by
delivery (either actual delivery or by attestation procedures established by the
Company) of previously owned whole shares of Stock (which the Optionee has held
for at least six months prior to the delivery of such shares or which the
Optionee purchased on the open market and in each case for which the Optionee
has good title, free and clear of all liens and encumbrances) having an
aggregate Fair Market Value, determined as of the date of exercise, equal to the
aggregate purchase price payable pursuant to the Option by reason of such
exercise, (C) if legally permissible, in cash by a broker-dealer acceptable to
the Company to whom the Optionee has submitted an irrevocable notice of exercise
or (D) by a combination of (A) and (B), and (2) by executing such documents as
the Company may reasonably request. Any fraction of a share of Stock which would
be required to pay such purchase price shall be disregarded and the remaining
amount due shall be

                                       2

<PAGE>

paid in cash. No certificate representing a share of Stock shall be issued or
delivered until the full purchase price therefor and any withholding taxes
thereon, as described in Section 3.3, have been paid (or arrangement made for
such payment to the Company's satisfaction). If shares of Stock have not been
registered under the Securities Act at the time the Option is exercised, if
requested by the Company the Optionee shall concurrently with the exercise of
the Option deliver to the Company an executed Investment Representation
Statement in the form attached hereto as Exhibit B.

     2.4. Termination of Option. (a) In no event may the Option be exercised
after it terminates as set forth in this Section 2.4. The Option shall
terminate, to the extent not earlier terminated pursuant to Section 2.2 or
earlier exercised pursuant to Section 2.3, at 5:00 p.m. Central time on the
Expiration Date.

     (b)  In the event that rights to purchase all or a portion of the shares of
Stock subject to the Option expire or are exercised, cancelled or forfeited, the
Optionee shall, upon the Company's request, promptly return this Agreement to
the Company for full or partial cancellation, as the case may be. Such
cancellation shall be effective regardless of whether the Optionee returns this
Agreement. If the Optionee continues to have rights to purchase shares of Stock
hereunder, the Company shall, within 10 days of the Optionee's delivery of this
Agreement to the Company, either (i) mark this Agreement to indicate the extent
to which the Option has expired or been exercised, cancelled or forfeited or
(ii) issue to the Optionee a substitute stock option agreement applicable to
such rights, which agreement shall otherwise be substantially similar to this
Agreement in form and substance.

     3.   Additional Terms and Conditions of Option.

     3.1. Transferability of Option; Transferability of Stock. (a) The Option
may not be transferred other than (i) by will or the laws of descent and
distribution, (ii) pursuant to the beneficiary designation procedures set forth
in Section 4.4 or (iii) by gift to a Permitted Transferee. During the Optionee's
lifetime the Option is exercisable only by the Optionee (or the Optionee's Legal
Representative) or a Permitted Transferee (or a Permitted Transferee's Legal
Representative). Except to the extent permitted by the second preceding
sentence, the Option may not be sold, transferred, assigned, pledged,
hypothecated, encumbered or otherwise disposed of (whether by operation of law
or otherwise) or be subject to execution, attachment or similar process. Upon
any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or
otherwise dispose of the Option, the Option and all rights hereunder shall
immediately become null and void.

     (b)  The shares of Stock purchased pursuant to the exercise of the Option
shall be subject to transfer restrictions and repurchase by the Company upon
such terms and conditions as set forth in the Exercise Notice and Share
Repurchase Agreement.

     3.2. Investment Representation. The Optionee hereby represents and
covenants that (a) any share of Stock purchased upon exercise of the Option will
be purchased for investment and not with a view to the distribution thereof
within the meaning of the Securities Act, unless such purchase has been
registered under the Securities Act and any applicable state securities laws;
(b) any subsequent sale of any such share shall be made either pursuant to an
effective registration statement under the Securities Act and any applicable
state securities laws, or pursuant to an exemption from registration under the
Securities Act and such

                                       3

<PAGE>

state securities laws; and (c) if requested by the Company, the Optionee shall
submit a written statement, in a form satisfactory to the Company, to the effect
that such representation (x) is true and correct as of the date of purchase of
any shares hereunder or (y) is true and correct as of the date of any sale of
any such shares, as applicable. As a further condition precedent to any exercise
of the Option, the Optionee shall comply with all regulations and requirements
of any regulatory authority having control of or supervision over the issuance
or delivery of the shares and, in connection therewith, shall execute any
documents which the Board shall in its sole discretion deem necessary or
advisable.

     3.3. Withholding Taxes. (a) As a condition precedent to the issuance or
delivery of Stock upon exercise of the Option, the Optionee shall, upon request
by the Company, pay to the Company in addition to the purchase price of the
shares, such amount as the Company may be required, under all applicable
Federal, state, local or other laws or regulations, to withhold and pay over as
income or other withholding taxes (the "Required Tax Payments") with respect to
such exercise of the Option. If the Optionee shall fail to advance the Required
Tax Payments after request by the Company, the Company may, in its discretion,
deduct any Required Tax Payments from any amount then or thereafter payable by
the Company to the Optionee.

     (b)  The Optionee shall satisfy his or her obligation to advance the
Required Tax Payments by means of (i) a cash payment to the Company or (ii) if
the Stock has been registered under the Securities Act and is publicly traded,
(A) a cash payment to the Company, (B) delivery to the Company (either actual
delivery or by attestation procedures established by the Company) of whole
shares of Stock having an aggregate Fair Market Value, determined as of the date
the obligation to withhold or pay taxes first arises in connection with the
Option (the "Tax Date"), equal to the Required Tax Payments, (C) authorizing the
Company to withhold whole shares of Stock which would otherwise be delivered
upon exercise of the Option having an aggregate Fair Market Value, determined as
of the Tax Date, equal to the Required Tax Payments, (D) if legally permissible,
a cash payment by a broker-dealer acceptable to the Company to whom the Optionee
has submitted an irrevocable notice of exercise or (E) any combination of (A),
(B) and (C). Shares of Stock to be delivered or withheld may not have a Fair
Market Value in excess of the amount determined by applying the minimum
statutory withholding rate. Any fraction of a share of Stock which would be
required to satisfy any such obligation shall be disregarded and the remaining
amount due shall be paid in cash. No certificate representing a share of Stock
shall be issued or delivered until the Required Tax Payments have been paid (or
arrangement made for such payment to the Company's satisfaction).

     3.4. Adjustment. In the event of any stock split, stock dividend,
recapitalization, reorganization, merger, consolidation, combination, exchange
of shares, liquidation, spin-off or other similar change in capitalization or
event, or any distribution to holders of Stock other than a regular cash
dividend, the number and class of securities subject to the Option and the
purchase price per security shall be appropriately adjusted by the Board
(including pursuant to a substitution), such adjustment to be made without an
increase in the aggregate purchase price. If any adjustment would result in a
fractional security being subject to the Option, the Company shall pay the
Optionee, in connection with the first exercise of the Option in whole or in
part occurring after such adjustment, an amount in cash determined by
multiplying (i) the fraction of such security (rounded to the nearest hundredth)
by (ii) the excess, if any, of (A) the Fair Market Value on the exercise date
over (B) the exercise price of the

                                       4

<PAGE>

Option. The decision of the Board regarding any such adjustment shall be final,
binding and conclusive.

     3.5.  Compliance with Applicable Law. The Option is subject to the
condition that if the listing, registration or qualification of the shares
subject to the Option upon any securities exchange or under any law, or the
consent or approval of any governmental body, or the taking of any other action
is necessary or desirable as a condition of, or in connection with, the purchase
or delivery of shares hereunder, the Option may not be exercised, in whole or in
part, and such shares shall not be delivered, unless such listing, registration,
qualification, consent, approval or other action shall have been effected or
obtained, free of any conditions not acceptable to the Company. The Company may
require that certificates evidencing shares of Stock delivered pursuant to the
exercise of the Option bear a legend indicating (i) that the sale, transfer or
other disposition thereof by the holder is prohibited except in compliance with
the Securities Act and the rules and regulations thereunder and (ii) such other
restrictions, if any, specified in the Exercise Notice and Share Repurchase
Agreement.

     3.6.  Delivery of Certificates. Upon the exercise of the Option, in whole
or in part, the Company shall deliver or cause to be delivered, subject to the
conditions of this Agreement, one or more certificates representing the number
of shares purchased against full payment therefor. The Company shall pay all
original issue or transfer taxes and all fees and expenses incident to such
delivery, except as otherwise provided in Section 3.3.

     3.7.  Option Confers No Right as Stockholder. The Optionee shall not be
entitled to any privileges of ownership with respect to any shares of Stock or
other equity security subject to the Option unless and until such shares are
purchased and delivered upon the exercise of the Option, in whole or in part,
and the Optionee becomes a stockholder of record with respect to such delivered
shares. The Optionee shall be subject to and bound by all of the terms and
conditions of any other agreement between the Company and the Optionee regarding
the shares of Stock purchased hereunder, including without limitation the
Exercise Notice and Share Repurchase Agreement.

     3.8.  Option Confers No Right to Continued Employment. In no event shall
the granting of the Option or its acceptance by the Optionee, or any provision
of this Agreement, give or be deemed to give the Optionee any right to continued
employment by the Company or any subsidiary or affiliate of the Company.

     3.9.  Decisions of Board. The Board shall have the right to resolve all
questions which may arise in connection with the Option or its exercise. Any
interpretation, determination or other action made or taken by the Board
regarding this Agreement shall be final, binding and conclusive.

     3.10. Company to Reserve Shares. The Company shall at all times prior to
the expiration or termination of the Option reserve and keep available, either
in its treasury or out of its authorized but unissued shares of Stock, the full
number of shares subject to the Option from time to time.

     3.11.  Change in Control.

     (a) (1) Notwithstanding any provision in this Agreement, in the event of a
Change in Control pursuant to Section (b)(3) or (4) below in connection with
which the holders of Stock receive shares of common stock that are registered
under Section 12 of the Exchange Act, the Option shall immediately become
exercisable in full and there shall be substituted for each share of Stock
subject to the Option, the number and class of shares into which each
outstanding share of Stock shall be converted pursuant to such Change in
Control. In the event of any such substitution, the purchase price per share
shall be appropriately adjusted by the Board (whose determination shall be
final, binding and conclusive), such adjustment to be made without an increase
in the aggregate purchase price.

     (2) Notwithstanding any provision in this Agreement, in the event of a
Change in Control pursuant to Section (b)(1) or (2) below, or in the event of a
Change in Control pursuant to Section (b)(3) or (4) below in connection with
which the holders of Stock receive consideration other than shares of common
stock that are registered under Section 12 of the Exchange Act, the Option shall
be surrendered to the Company and immediately canceled by the Company, and the
Optionee shall receive, within ten days of the occurrence of a Change in
Control, a cash payment from the Company in an amount equal to (i) the number of
shares of Stock then subject to the Option, multiplied by the excess, if any, of
the greater of (A) the highest per share price offered to stockholders of the
Company in any transaction whereby the Change in Control takes place or (B) the
Fair Market Value of a share of Stock on the date of occurrence of the Change in
Control, over the purchase price per share of Stock subject to the Option.

on or after December 31, 2002:

corporation controlled by the Company) shall become the beneficial owner of 40%
or more of the Outstanding Common Stock or 40% or more of the Outstanding Voting
Securities by reason of an acquisition by the Company, and such Person shall,
after such acquisition by the Company, become the beneficial owner of any

                 Exercise Notice and Share Repurchase Agreement

Patron Systems, Inc.

Attention:  Patrick J. Allin, Chief Executive Officer

     1.   Exercise of Option. Effective as of today, ___________, 20___, the
undersigned ("Optionee") hereby elects to exercise Optionee's option to purchase
_____ shares of the common stock, $.01 par value per share (the "Shares") of
Patron Systems, Inc. (the "Company") under and pursuant to the Patron Systems,
Inc. Stock Option Agreement dated ________, 20___ (the "Option Agreement").

     2.   Delivery of Payment. Optionee herewith delivers to the Company the
full purchase price of the Shares, as set forth in the Option Agreement.

     3.   Representations of Optionee. Optionee acknowledges that Optionee has
received, read and understands this Exercise Notice and Share Repurchase
Agreement (this "Agreement") and the Option Agreement and agrees to abide by and
be bound by their terms and conditions.

     4.   Rights as Shareholder. Until the issuance of the Shares (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 shareholder shall exist with respect to the Shares subject to
the Option, notwithstanding the exercise of the Option. The Shares shall be
issued to the Optionee as soon as practicable after the Option is exercised. No
adjustment shall be made for a dividend or other right for which the record date
is prior to the date of issuance.

     5.   Right of First Refusal. Before any Option Shares held by the Optionee
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Option Shares on the terms and conditions set forth in this Section
(the "Right of First Refusal").

     (a)  Notice of Proposed Transfer. The Holder of the Option Shares shall
deliver to the Company a written notice (the "Notice") stating: (i) the Holder's
bona fide intention to sell or otherwise transfer such Option Shares; (ii) the
name of each proposed purchaser or other transferee (the "Proposed Transferee");
(iii) the number of Option Shares to be transferred to each Proposed Transferee;
and (iv) the bona fide cash price or other consideration for which the Holder
proposes to transfer the Option Shares (the "Offered Price"), and the Holder
shall offer the Option Shares at the Offered Price to the Company or its
assignee(s).

<PAGE>

     (b)  Exercise of Right of First Refusal. At any time within ninety (90)
days after receipt of the Notice, the Company and/or its assignee(s) may, by
giving written notice to the Holder, elect to purchase some or all of the Option
Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.

     (c)  Purchase Price. The purchase price (the "Purchase Price") for the
Option Shares purchased by the Company or its assignee(s) under this Section
shall be the Offered Price. If the Offered Price includes consideration other
than cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

     (d)  Payment. Payment of the Purchase Price shall be made, at the option of
the Company or its assignee(s), in cash (by check), by cancellation of all or a
portion of any outstanding indebtedness of the Holder to the Company (or, in the
case of repurchase by an assignee, to the assignee), or by any combination
thereof within 90 days after receipt of the Notice or in such other manner and
at such other time mutually agreeable to the parties.

     (e)  Holder's Right to Transfer. If all of the Option Shares proposed in
the Notice to be transferred to a given Proposed Transferee are not purchased by
the Company and/or its assignee(s) as provided in this Section, then the Holder
may sell or otherwise transfer such Option Shares to that Proposed Transferee at
the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 120 days after the date of the Notice, that any
such sale or other transfer is effected in accordance with any applicable
securities laws and that the Proposed Transferee agrees in writing that the
provisions of this Section shall continue to apply to the Option Shares in the
hands of such Proposed Transferee. If the Option Shares described in the Notice
are not transferred to the Proposed Transferee within such period, a new Notice
shall be given to the Company, and the Company and/or its assignees shall again
be offered the Right of First Refusal before any Option Shares held by the
Holder may be sold or otherwise transferred.

     6.  Share Repurchase. (a) If the Optionee's employment with the Company
terminates for any reason or if the Optionee breaches any covenant set forth in
any employment, noncompetition, nonsolicitation, confidentiality, inventions or
similar agreement between the Company and the Optionee (an "Employment
Agreement") at any time, the Company or its assignee shall have the right (but
not the obligation) in its sole discretion to repurchase any or all of the
Option Shares held by such Optionee (the "Share Repurchase Option"). If the
Company or its assignee repurchases any Option Shares pursuant to this Section,
it shall pay to the Optionee or his or her Legal Representative a purchase price
equal to: (i) in the case of the Optionee's termination of employment for any
reason other than Cause, the Fair Market Value of such Option Shares as of the
date the Company or its assignee elects to repurchase such Option Shares; and
(ii) in the case of the Optionee's termination of employment for Cause or the
Optionee's breach of an Employment Agreement, the lesser of the exercise price,
as adjusted pursuant to Section 3.4 of the Option Agreement, and the Fair Market
Value of the Option Shares as of the date the Company or its assignee elects to
repurchase such Option Shares.

     (a)  The right of the Company or its assignee to repurchase such Option
Shares shall expire 90 days after the date of the Optionee's termination of
employment or breach, as

                                      A-2

<PAGE>

applicable, or, if later, 90 days after the date the Option is exercised. The
repurchase rights shall be in addition to any other rights or remedies that the
Company or its assignee may have under this Agreement or otherwise. If the
Company or its assignee elects to repurchase any Option Shares pursuant to this
Section, (i) the Company or its assignee shall deliver to the Optionee, within
the 90-day period described in this Section, a notice setting forth the number
of Option Shares which it has elected to repurchase and (ii) the Optionee shall
deliver to the Company a certificate or certificates for the Option Shares being
repurchased, duly endorsed or otherwise in proper form for transfer, against
payment of the required repurchase price in cash (by check).

     7.  Termination of Right of First Refusal and Share Repurchase Option. The
Right of First Refusal and Share Repurchase Option, as set forth in Sections 5
and 6 hereof, shall terminate as to any Option Shares upon the first sale of
shares of common stock of the Company to the general public pursuant to a
registration statement filed with and declared effective by the Securities and
Exchange Commission under the Securities Act.

                   Patron Systems, Inc. Stock Option Agreement

                       Investment Representation Statement

Optionee:                  Richard Linting

Company:                   Patron Systems, Inc.

Security:                  Common Stock, $.01 par value

Number of Shares:          _____________________

Aggregate Exercise Price:  _____________________

Date:                      _____________________

In connection with the purchase of the above-listed Securities, the undersigned
Optionee represents to the Company the following:

     (a)  Optionee is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities. Optionee is
acquiring these Securities for investment for Optionee's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

     (b)  Optionee acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Optionee's
investment intent as expressed herein. In this connection, Optionee understands
that, in the view of the Securities and Exchange Commission, the statutory basis
for such exemption may be unavailable if Optionee's representation was
predicated solely upon a present intention to hold these Securities for the
minimum capital gains period specified under tax statutes, for a deferred sale,
for or until an increase or decrease in the market price of the Securities, or
for a period of one year or any other fixed period in the future. Optionee
further understands that: (i) the Securities must be held indefinitely unless
they are subsequently registered under the Securities Act or an exemption from
such registration is available; (ii) the Company is under no obligation to
register the Securities; and (iii) the certificate evidencing the Securities
will be imprinted with a legend which prohibits the transfer of the Securities
unless they are registered or such registration is not required in the opinion
of counsel satisfactory to the Company, and any other legend required under
applicable state securities laws.

     (c)  Optionee is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions. Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Option to the Optionee, the exercise will be
exempt from registration under the Securities Act. In the event the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer
period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of certain of the
conditions specified by Rule 144, including: (1) the resale being made through a
broker in an unsolicited "broker's transaction" or in transactions directly with
a market maker (as said term is defined under the Securities Exchange Act of
1934); and, in the case of an affiliate, (2) the availability of certain public
information about the Company, (3) the amount of Securities being sold during
any three month period not exceeding the limitations specified in Rule 144(e)
and (4) the timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of the grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than one year after the later of the date the Securities were
sold by the Company or the date the Securities were sold by an affiliate of the
Company, within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than one year, the satisfaction of the conditions set forth in
sections (1), (2), (3) and (4) of the paragraph immediately above.

     (d)  Optionee further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and other than pursuant to Rules
144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk. Optionee understands that no assurances can be given that any
such other registration exemption will be available in such event.

                                             Signature of Optionee:

                                             ___________________________________
