                          REGISTRATION RIGHTS AGREEMENT

THIS REGISTRATION RIGHTS AGREEMENT ("Agreement"), dated as of November 9, 2001,
is among INTEGRATED SECURITY SYSTEMS, INC., a Delaware corporation (the
"Company"), and C. A. RUNDELL, JR. ("Rundell").

                                   WITNESSETH:

         WHEREAS, the Company has issued to Rundell five-year warrants to
purchase 250,000 shares of Common Stock ("Common Stock", such shares together,
with all other shares of Common Stock heretofore or hereafter issued to Rundell
or issuable to Rundell upon conversion or exercise of the Company's securities,
hereinafter referred to as the "Registrable Shares");

         WHEREAS, the Registrable Shares have not been registered under the
Securities Act of 1933, as amended (the "1933 Act"), and the Company has agreed
to grant to Rundell certain registration rights with respect to the Registrable
Shares as set forth herein.

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

1. Demand Registration.

         (a) The Company hereby agrees to use its best efforts to register all
or any portion of the Registrable Shares on one (1) occasion upon receipt of a
written request from a holder (the "Holder" or "Holders") of record of the
Registrable Shares that the Company file a registration statement under the 1933
Act covering the registration of the Registrable Shares then outstanding. The
Company shall, within twenty (20) days of its receipt thereof, give written
notice of such request to all holders of record of Registrable Shares. The
Holders of said Registrable Shares shall then have fifteen (15) days from the
date of mailing of such notice by the Company to request that all or a portion
of their respective Registrable Shares be included in said registration.

         (b) If the Holders intend to distribute the Registrable Shares covered
by their request by means of an underwriting, they shall so advise the Company
as a part of their request made pursuant to this Agreement, and the Company
shall include such information in the written notice to the other Holders of
Registrable Shares referred to in Section 1(a) above. In such event, the right
of any Holder to include its Registrable Shares in such registration shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Shares in the underwriting (unless
otherwise mutually agreed by the Company, the underwriter, the Initiating Holder
and such Holder) is limited to the extent provided herein. All Holders proposing
to distribute their securities through such underwriting shall (together with
the Company as provided in Section 3(e) below) enter into an underwriting
agreement in customary form with the underwriter or underwriters selected for
such underwriting by mutual agreement of the Company and the Initiating Holder,
which agreement shall not be unreasonably withheld. Notwithstanding any other

                                       1
<PAGE>

provision of this Section 1, if the underwriter advises the Initiating Holder
and the Company in writing that marketing factors require a limitation of the
number of shares to be underwritten, then the Initiating Holder shall so advise
all Holders of Registrable Shares which would otherwise be underwritten pursuant
hereto, and the number of shares of Registrable Shares that may be included in
the underwriting shall be allocated on a pro rata basis among all Holders that
have requested to participate in such registration.

         (c) Each such registration shall remain effective for a period of one
hundred eighty (180) days, unless the Initiating Holder requests that such
registration be terminated prior to the expiration of such period.

         (d) If, after a registration statement becomes effective, the Company
advises the Holders that the registration statement is required to be amended
under applicable federal securities laws, the Holders shall suspend any further
sales of their Registrable Shares, until the Company advises them that the
registration statements has been amended, but not more than thirty (30) days.
The one hundred eighty (180)-day time period referred to in subsection (c)
during which the registration statement must be kept current after its effective
date shall be extended for an additional number of business days equal to the
number of business days during which the right to sell the Registrable Shares
was suspended pursuant to the preceding sentence.

         (e) the Company shall have the right to exclude an underwriter not
reasonably acceptable to it.

2. "Piggy-Back" Registration.

         If the Company proposes to register any of its capital stock under the
1933 Act in connection with the public offering of such securities for its own
account or for the account of its security Holders, other than Holders of
Registrable Shares pursuant hereto (a "Piggy-Back Registration Statement"),
except for (i) a registration relating solely to the sale of securities to
participants in the Company's stock plans or employee benefit plans or (ii) a
registration relating solely to an transaction for which Form S-4 may be used,
then:

         (a) the Company shall give written notice of such determination to each
Holder of Registrable Shares, and each such Holder shall have the right to
request, by written notice given to the Company within fifteen (15) days of the
date that such written notice was mailed by the Company to such Holder, that a
specific number of Registrable Shares held by such Holder be included in the
Piggy-Back Registration Statement (and related underwritten offering, if any);

         (b) If the Piggy-Back Registration Statement relates to an underwritten
offering, the notice given to each Holder shall specify the name or names of the
managing underwriter or underwriters for such offering. In addition, such notice
shall also specify the number of securities to be registered for the account of
the Company and for the account of its shareholders (other than the Holders of
Registrable Shares), if any;

         (c) If the Piggy-Back Registration Statement relates to an underwritten
offering, each Holder of Registrable Shares to be included therein must agree
(i) to sell such Holder's Registrable Shares on the same basis as provided in
the underwriting arrangement approved by the Company, and (ii) to timely
complete and execute all questionnaires, powers of attorney,

                                       2
<PAGE>

indemnities, hold-back agreements, underwriting agreements and other documents
required under the terms of such underwriting arrangements or by the SEC or by
any state securities regulatory body;

         (d) If the managing underwriter or underwriters for the underwritten
offering under the Piggy-Back Registration Statement determines in writing that
inclusion of all or any portion of the Registrable Shares in such offering would
materially and adversely affect the ability of the underwriters for such
offering to sell all of the securities requested to be included for sale in such
offering, the aggregate number of Registrable Shares that may be sold by the
Holders shall be limited to such number of Registrable Shares, if any, that the
managing underwriter or underwriters determine may be included therein without
such adverse effect, as provided below. If the number of securities proposed to
be sold in such underwritten offering exceeds the number of securities that may
be sold in such offering, there shall be included in the offering, first, up to
the maximum number of securities to be sold by the Company for its own account,
and, second, the balance, if any, of the Registrable Shares requested to be
included therein by the Holders;

         (e) Holders of Registrable Shares shall have the right to withdraw
their Registrable Shares from the Piggy-Back Registration Statement, but if the
same relates to an underwritten offering, they may only do so during the time
period and on the terms agreed upon among the underwriters for such underwritten
offering and the Holders of Registrable Shares;

         (f) The Holders will advise the Company at the time a registration
becomes effective whether the Registrable Shares included in the registration
will be underwritten or sold directly by the Holders;

         (g) All demand and piggy-back registration rights of the Holders shall
terminate when all of the Registrable Shares then outstanding may be sold
pursuant to Rule 144(k).

3. Obligations of the Company.

         Whenever required to effect the registration of any Registrable Shares
pursuant to this Agreement, the Company shall, as expeditiously as reasonably
possible:

              (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Shares and use all reasonable efforts to cause such
registration statement to become effective, and keep such registration statement
effective until the sooner of all such Registrable Shares having been
distributed, or until one hundred twenty (120) days have elapsed since such
registration statement became effective (subject to extension of this period as
provided below);

              (b) Prepare and file with the SEC such amendments and supplements
to such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
1933 Act with respect to the disposition of all securities covered by such
registration statement, or one hundred twenty (120) days have elapsed since such
registration statement became effective (subject to the extension of this period
as provided below);

              (c) Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
1933 Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Shares owned by them;

                                       3
<PAGE>

         (d) Use all reasonable efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify as a broker-dealer in any states or jurisdictions
or to do business or to file a general consent to service of process in any such
states or jurisdictions;

         (e) In the event of any underwritten public offering, enter into an
underwriting agreement with the managing underwriter of such offering, in usual
and customary form reasonably satisfactory to the Company and the Holders of a
majority of the Registrable Shares to be included in such offering;

         (f) Notify each Holder of Registrable Shares covered by such
registration statement, at any time when a prospectus relating thereto and
covered by such registration statement is required to be delivered under the
1933 Act, of the happening of any event as a result of which the prospectus
included in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing; and

         (g) In the event of the notification provided for in Section 3(f)
above, the Company shall use its best efforts to prepare and file with the SEC
(and to provide copies thereof to the Holders) as soon as reasonably possible an
amended prospectus complying with the 1933 Act, and the period during which the
prospectus referred to in the notice provided for in Section 3(f) above cannot
be used and the time period prior to the use of the amended prospectus referred
to in this Section 3(g) shall not be counted in the one hundred twenty (120)-day
period of this Section 3.

4. Furnish Information.

         (a) It shall be a condition precedent to the obligations of the Company
that the selling Holders shall furnish to the Company any and all information
reasonably requested by the Company, its officers, directors, employees,
counsel, agents or representatives, the underwriter or underwriters, if any, and
the SEC or any other Governmental Authority, including, but not limited to: (i)
such information regarding themselves, the Registrable Shares held by them, and
the intended method of disposition of such securities, as shall be required to
effect the registration of their Registrable Shares; and (ii) the identity of
and compensation to be paid to any proposed underwriter or broker-dealer to be
employed in connection therewith.

         (b) In connection with the preparation and filing of each registration
statement registering Registrable Shares under the 1933 Act, the Company shall
give the Holders of Registrable Shares on whose behalf such Registrable Shares
are to be registered and their underwriters, if any, and their respective
counsel and accountants, such access to copies of the Company's records and
documents and such opportunities to discuss the business of the Company with its
officers and the independent public accountants who have certified its financial
statements as shall be necessary or appropriate to conduct a due diligence
investigation, within the meaning of the 1933 Act.

                                       4

5. Expenses of Registration.

         All expenses, other than underwriting discounts and commissions
applicable to the Registrable Shares sold by selling Holders, incurred in
connection with the registration of the Registrable Shares pursuant to this
section, including, without limitation, all registration, filing and
qualification fees, printer's expenses, accounting and legal fees and expenses
of the Company and Holders, shall be borne by the Company.

6. Other Registration Rights.

         No registration rights have been granted by the Company, other than as
set forth on the filings made by the Company with the SEC. The Company shall not
grant any registration rights in the future, without the consent of Rundell.

7. Indemnification Regarding Registration Rights.

         If any Registrable Shares are included in a registration statement
pursuant to this Agreement:

         (a) To the extent permitted by law, the Company will indemnify and hold
harmless each Holder, the officers and directors of each Holder, any underwriter
(as defined in the 1933 Act) for such Holder and each person, if any, who
controls such Holder or underwriter within the meaning of the 1933 Act or the
Securities Exchange Act of 1934, as amended (the "1934 Act"), against any
losses, claims, damages, liabilities (joint or several) or any legal or other
costs and expenses reasonably incurred by them in connection with investigating
or defending any such loss, claim, damage, liability or action to which they may
become subject under the 1933 Act, the 1934 Act or state law, insofar as such
losses, claims, damages, costs, expenses or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements,
omissions or violations (each a "Violation"): (i) any untrue statement or
alleged untrue statement of a material fact with respect to the Company or its
securities contained in such registration statement, including any preliminary
prospectus or final prospectus contained therein or any amendments or
supplements therein; (ii) the omission or alleged omission to state therein a
material fact with respect to the Company or its securities required to be
stated therein or necessary to make the statements therein not misleading; or
(iii) any violation or alleged violation by the Company of the 1933 Act, the
1934 Act, any state securities law or any rule or regulation promulgated under
the 1933 Act, the 1934 Act or any state securities law. Notwithstanding the
foregoing, the indemnity agreement contained in this Section 7(a) shall not
apply and the Company shall not be liable in any such case for any such loss,
claim, damage, costs, expenses, liability or action to the extent that it arises
out of or is based upon a Violation which occurs in reliance upon and in
conformity with written information furnished expressly for use in connection
with such registration by any such Holder, underwriter or controlling person.

         (b) To the extent permitted by law, each Holder who participates in a
registration pursuant to the terms and conditions of this Agreement shall
indemnify and hold harmless the Company, each of its directors and officers who
have signed the registration statement, each Person, if any, who controls the
Company within the meaning of the 1933 Act, the 1934 Act, any state securities
law or any rule or regulation promulgated under the 1933 Act, the 1934 Act or
any state securities law, each of the Company's employees, agents, counsel and
representatives, any underwriter and any other Holder selling securities in such
registration statement, or any of its directors or officers, or any person who
controls such Holder, against any losses, claims, damages,

                                       5
<PAGE>

costs, expenses, liabilities (joint or several) to which the Company or any such
director, officer, controlling person, employee, agent, representative,
underwriter, or other such Holder, or director, officer or controlling person
thereof, may become subject, under the 1933 Act, the 1934 Act or other federal
or state law, only insofar as such losses, claims, damages, costs, expenses or
liabilities or actions in respect thereto arise out of or are based upon any
Violation, in each case only to the extent and only to the extent that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder expressly for use in connection with such. Each such
Holder will indemnify any legal or other expenses reasonably incurred by the
Company or any such director, officer, employee, agent representative,
controlling person, underwriter or other Holder, or officer, director or of any
controlling person thereof, in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this Section 7(b) shall not apply to amounts
paid in settlement of any such loss, claim, damage, costs, expenses, liability
or action if such settlement is effected without the prior written consent of
the Holder.

         (c) Promptly after receipt by an indemnified party under this Section 7
of notice of the commencement of any action (including any governmental action),
such indemnified party will, if a claim in respect thereof is to be made against
any indemnifying party under this Section 7, deliver to the indemnifying party a
written notice of the commencement thereof and the indemnifying party shall have
the right to participate in, and, to the extent the indemnifying party so
desires, jointly with any other indemnifying party similarly noticed, to assume
the defense thereof with counsel mutually satisfactory to the parties; provided,
however, that an indemnified party shall have the right to retain its own
counsel, with the reasonable fees and expenses of such counsel to be paid by the
indemnifying party, if representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or
potential conflict of interests between such indemnified party and any other
party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action shall not relieve the indemnifying party of its
obligations under this Section 7, except to the extent that the failure results
in a failure of actual notice to the indemnifying party and such indemnifying
party is materially prejudiced in its ability to defend such action solely as a
result of the failure to give such notice.

         (d) If the indemnification provided for in this Section 7 is
unavailable to an indemnified party under this Section 7 in respect of any
losses, claims, damages, costs, expenses, liabilities or actions referred to
herein, then each indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, costs, expenses, liabilities or
actions in such proportion as is appropriate to reflect the relative fault of
the Company, on the one hand and of the Holder, on the other, in connection with
the Violation that resulted in such losses, claims, damages, costs, expenses,
liabilities or actions. The relative fault of the Company, on the one hand, and
of the Holder, on the other, shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of the material fact or
the omission to state a material fact relates to information supplied by the
Company or by the Holder, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

         (e) The Company, on the one hand, and the Holders, on the other, agree
that it would not be just and equitable if contribution pursuant to this Section
7 were determined by a pro

                                       6
<PAGE>

rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an indemnified party as a result of
losses, claims, damages, costs, expenses, liabilities and actions referred to in
the immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any reasonable legal or other expenses incurred by
such indemnified party in connection with defending any such action or claim.
Notwithstanding the provisions of this Section 7, neither the Company nor the
Holders shall be required to contribute any amount in excess of the amount by
which the total price at which the securities were offered to the public exceeds
the amount of any damages which the Company or each such Holder has otherwise
been required to pay by reason of such Violation. No person guilty of fraudulent
misrepresentations (within the meaning of Section 11(f) of the 1933 Act) shall
be entitled to contribution from any person who is not guilty of such fraudulent
misrepresentation.

8. Reports Under the 1934 Act.

         So long as the Company has a class of securities registered pursuant to
Section 13 of the 1934 Act, with a view to making available to the Holders the
benefits of Rule 144 promulgated under the 1933 Act ("Rule 144") and any other
rule or regulation of the SEC that may at any time permit a Holder to sell
securities of the Company to the public without registration or pursuant to a
registration on Form S-3, if applicable, the Company agrees to use its
reasonable efforts to:

         (a) Make and keep public information available, as those terms are
understood and defined in Rule 144, at all times;

         (b) File with the SEC in a timely manner all reports and other
documents required of the Company under the 1933 Act and the 1934 Act;

         (c) Furnish to any Holder, so long as the Holder owns any Registrable
Shares, (i) forthwith upon request a copy of the most recent annual or quarterly
report of the Company and such other SEC reports and documents so filed by the
Company, and (ii) such other information (but not any opinion of counsel) as may
be reasonably requested by any Holder seeking to avail himself of any rule or
regulation of the SEC which permits the selling of any such securities without
registration or pursuant to such form.

9. Assignment of Registration Rights.

         Subject to the terms and conditions of this Agreement and the right to
cause the Company to register Registrable Shares pursuant to this Agreement may
be assigned by Holder to any transferee or assignee of such securities; provided
that said transferee or assignee is a transferee or assignee of at least ten
percent (10%) of the Registrable Shares and provided that the Company is, within
a reasonable time after such transfer, furnished with written notice of the name
and address of such transferee or assignee and the securities with respect to
which such registration rights are being assigned; and provided, further, that
such assignment shall be effective only if immediately following such transfer
the further disposition of such securities by the transferee or assignee is
restricted under the 1933 Act; it being the intention that so long as Holder
holds any Registrable Shares hereunder, either Holder or its transferee or
assignee of at least ten percent may exercise the registration rights hereunder.

                                       7
<PAGE>

10. Other Matters.

         (a) Each Holder of Registrable Shares hereby agrees by acquisition of
such Registrable Shares that, with respect to each offering of the Registrable
Shares, whether each Holder is offering such Registrable Shares in an
underwritten or nonunderwritten offering, such Holder will comply with
Regulation M or such other or additional anti-manipulation rules then in effect
until such offering has been completed, and in respect of any nonunderwritten
offering, in writing will inform the Company, any other Holders who are selling
shareholders, and any national securities exchange upon which the securities of
the Company are listed, that the Registrable Shares have been sold and will,
upon the Company's request, furnish the distribution list of the Registrable
Shares. In addition, upon the request of the Company, each Holder will supply
the Company with such documents and information as the Company may reasonably
request with respect to the subject matter set forth and described in this
Section 10.

         (b) Each Holder of Registrable Shares hereby agrees by acquisition of
such Registrable Shares that, upon receipt of any notice from the Company of the
happening of any event which makes any statement made in the registration
statement, the prospectus or any document incorporated therein by reference,
untrue in any material respect or which requires the making of any changes in
the registration statement, the prospectus or any document incorporated therein
by reference, in order to make the statements therein not misleading in any
material respect, such Holder will forthwith discontinue disposition of
Registrable Shares under the prospectus related to the applicable registration
statement until such Holder's receipt of the copies of the supplemented or
amended prospectus, or until it is advised in writing by the Company that the
use of the prospectus may be resumed, and has received copies of any additional
or supplemental filings which are incorporated by reference in the prospectus.

11. Waivers and Modifications.

         All modifications, consents, amendments or waivers (herein "Waivers")
of any provision of this Agreement shall be effective only if the same shall be
in writing by Rundell and then shall be effective only in the specific instance
and for the purpose for which given. No notice or demand given in any case shall
constitute a waiver of the right to take other action in the same, similar or
other instances without such notice or demand. No failure to exercise, and no
delay in exercising, on the part of Rundell, any right hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise thereof preclude
any other or further exercise thereof or the exercise any other right. The
rights of Rundell hereunder shall be in addition to all other rights provided by
law.

         12. Choice of Forum; Consent to Service of Process and Jurisdiction.

         Any suit, action or proceeding against the Company with respect to this
Agreement or any judgment entered by any court in respect thereof, may be
brought in the courts of the State of Texas, County of Dallas, or in the United
States federal courts located in the State of Texas, as Rundell in its sole
discretion may elect, and the Company hereby submits to the nonexclusive
jurisdiction of such courts for the purpose of any such suit, action or
proceeding. The Company hereby agrees that service of all writs, process and
summonses in any such suit, action or proceeding brought in the State of Texas
may be brought upon, and the Company hereby irrevocably appoints, the CT
Corporation System, Dallas, Texas, as its true and lawful attorney-in-fact in
the name, place

                                       8
<PAGE>

and stead of the Company to accept such service of any and all such writs,
process and summonses. The Company hereby irrevocably waives any objections
which it may now or hereafter have to the laying of venue of any suit, action or
proceeding arising out of or relating to this Agreement or any Note brought in
such courts, and hereby further irrevocably waives any claim that any such suit,
action or proceeding brought in any such court has been brought in any
inconvenient forum.

13. Invalid Provisions.

         If any provision of this Agreement is held to be illegal, invalid or
unenforceable under present or future laws during the term of this Agreement,
such provision shall be fully severable; this Agreement shall be construed and
enforced as if such illegal, invalid or unenforceable provision had never
comprised a part of this Agreement; and the remaining provisions of this
Agreement shall remain in full force and effect and shall not be affected by the
illegal, invalid or unenforceable provision or by its severance from this
Agreement. Furthermore, in lieu of each such illegal, invalid or unenforceable
provision shall be added as part of this Agreement a provision mutually
agreeable to the Company and Rundell as similar in terms to such illegal,
invalid or unenforceable provision as may be possible and be legal, valid and
enforceable. In the event the Company and Rundell are unable to agree upon a
provision to be added to this Agreement within a period of ten (10) business
days after a provision of this Agreement is held to be illegal, invalid or
unenforceable, then a provision acceptable to independent arbitrators, such to
be selected in accordance with the provisions of the American Arbitration
Association, as similar in terms to the illegal, invalid or unenforceable
provision as is possible and be legal, valid and enforceable shall be added
automatically to this Agreement. In either case, the effective date of the added
provision shall be the date upon which the prior provision was held to be
illegal, invalid or unenforceable.

14. Binding Effect.

         This Agreement shall be binding upon and inure to the benefit of the
Company and Rundell and their respective successors, assigns and legal
representatives; provided, however, that the Company may not, without the prior
written consent of Rundell, assign any rights, powers, duties or obligations
thereunder.

15. No Third Party Beneficiary.

         The parties do not intend the benefits of this Agreement to inure to
any third party, nor shall this Agreement be construed to make or render Rundell
liable to any materialman, supplier, contractor, subcontractor, purchaser or
lessee of any property owned by the Company, or for debts or claims accruing to
any such persons against the Company. Notwithstanding anything contained herein,
no conduct by any or all of the parties hereto, before or after signing this
Agreement, shall be construed as creating any right, claim or cause of action
against Rundell, or any of its officers, directors, agents or employees, in
favor of any materialman, supplier, contractor, subcontractor, purchaser or
lessee of any property owned by the Company, nor to any other person or entity
other than the Company.

                                       9

16. Entirety.

         This Agreement and any other documents or instruments issued or entered
into pursuant hereto and thereto contain the entire agreement between the
parties and supersede all prior agreements and understandings, written or oral
(if any), relating to the subject matter hereof and thereof.

17. Headings.

         Section headings are for convenience of reference only and, except as a
means of identification of reference, shall in no way affect the interpretation
of this Agreement.

18. Survival.

                              EMPLOYMENT AGREEMENT

SBS TECHNOLOGIES, INC. ("Company") and Dan Moore ("Employee") agree:

         1.       EMPLOYMENT. Company employs Employee for the period beginning
                  on the date of this Employment Agreement and ending upon
                  discharge or resignation of Employee (the "Employment
                  Period"). During the Employment Period, Employee will serve in
                  the capacities determined by the Company. Employee will devote
                  sufficient time and energies to the business of Company to
                  accomplish the duties assigned, will perform to the best of
                  Employee's ability all duties assigned to Employee by Company
                  and will devote Employee's best efforts to advance the
                  interests of Company. Employee will have the power and
                  authority determined by Company.

         2.       REIMBURSEMENT OF EXPENSES. Company recognizes that Employee in
                  performing Employee's duties hereunder, may be required to
                  spend sums of money in connection with those duties for the
                  benefit of Company. Employee may present to Company an
                  itemized voucher listing expenses paid by Employee in the
                  performance of Employee's duties on behalf of Company, and on
                  presentation of such itemized voucher, Company will reimburse
                  Employee for all reasonable expenses itemized thereon,
                  including, but not limited to, travel, meals, lodging,
                  entertainment, and promotion with respect to all activities
                  approved in advance by the Company. Employee may receive
                  advances from Company for anticipated expenses. Employee
                  agrees that the amount by which an advance exceeds actual
                  expenses ("Amount") will be promptly refunded to Company upon
                  determination by Company that it is due, that the Amount may
                  be deducted from any payments of any nature (including without
                  limitation salary) owed by Company to employee, and that the
                  Amount will constitute a debt from Employee to Company,
                  enforceable by Company in all respects as if Employee had
                  executed a promissory note or other instrument acknowledging
                  the debt, bearing interest at a rate of 10% per year from the
                  date repayment is due and payable in full on demand without
                  set-off or deduction.

         3.       SICK LEAVE AND DISABILITY. Employee will be entitled to sick
                  leave for the number of days determined by Company ("Sick
                  Leave"). Employee will be considered to be disabled during any
                  period in excess of Sick Leave during which Employee is unable
                  to work because of illness or incapacity ("Disability
                  Period"). Employee will be entitled to receive Employee's full
                  salary during Sick Leave and will be deemed to be on leave,
                  without pay, during the Disability Period. If Employee is
                  unable to work for a period in excess of 180 days, the
                  Employee, at the discretion of the Board of Directors of
                  Company, will be considered to have resigned. In no event will
                  Employee be entitled to payment or other compensation for
                  unused Sick Leave or Disability Period, unless required by law
                  or otherwise provided in a policy or employment manual adopted
                  by the Board of Directors of Company.

         4.       RESTRICTIONS. Employee may not during the Employment Period,
                  directly or indirectly, own, manage, operate, invest in,
                  control, be employed by, participate in, be a financial
                  sponsor of, or be connected in any manner with the ownership,
                  management, operation or control of any business which
                  competes with a business conducted by Company at any time
                  during the Employment Period or a business which Employee
                  knows, during the Employment Period, that Company intends to
                  conduct. The ownership restriction applies, however, only in
                  the Employee owns a beneficial interest of 5% or more the
                  capital or profits of the business.

         5.       RESIGNATION AND DISCHARGE. Employee may resign by giving two
                  weeks' written notice to Company before resigning. Employee's
                  death will constitute a voluntary resignation. Company

EMPLOYMENT AGREEMENT - PAGE 1

<PAGE>

                  may discharge Employee without cause upon two weeks' notice.
                  If the Employment Period is terminated by resignation or
                  discharge without cause, Employee will be paid Employee's
                  salary on a pro-rata basis through the effective date of
                  resignation or discharge ("Effective Date"), and if requested
                  by Company, employee will continue to render Employee's
                  services through the Effective Date. If Employee refuses, upon
                  Company's requests, or fails to render services competently
                  and in good faith to the Company's benefit through the
                  Effective Date, Company may deem the Effective Date to be the
                  date of refusal or failure, as the case may be. If during the
                  Employment Period, Employee violates any provision or
                  restriction or fails to perform any obligation contained in
                  this Employment Agreement or in any Company policy or Company
                  employment manual or practice, or, unless otherwise provided
                  by Company policy or Company employment manual, (a) is
                  reasonably believed by Company (i) to have failed to comply
                  with any employment or nondiscrimination or similar law,
                  regulation or policy, (ii) to abuse, as determined by the
                  Company, alcohol or to use drugs, (other than as prescribed by
                  Employee's physician), or (b) refuses to submit to testing for
                  alcohol or drugs, or (c) is reasonably believed by Company to
                  have committed or is charged with any felony or misdemeanor
                  (except minor traffic violations and similar offenses),
                  Company may immediately discharge Employee without liability
                  for salary after the date of the discharge and without any
                  other liability to Employee. In no event will Employee be
                  entitled, upon resignation or discharge with or without cause,
                  to payment for sick leave or similar benefits of any kind
                  unless required by law or otherwise provided in a policy or
                  employment manual adopted by the Board of Directors of
                  Company.

         6.       CONFIDENTIAL INFORMATION. Employee acknowledges and recognizes
                  that Employee is, or will be, employed by Company in a
                  confidential relationship and may receive and have access to
                  the confidential business information, customer names,
                  contracts and other customer data, business methods,
                  techniques and trade secrets of Company ("Confidential
                  Information"). Employee may develop ideas, conceptions,
                  inventions, processes, methods, products and improvements; and
                  Employee may receive disclosures of ideas, conceptions,
                  inventions, processes, methods, products and improvements made
                  by other employees of Company ("Company Inventions"). Employee
                  may participate with Company in improving and developing
                  Confidential Information and Company Inventions. Confidential
                  Information and Company Inventions developed on behalf of
                  Company are neither commonly known nor readily accessible to
                  others and are used by Company in its business to obtain a
                  competitive advantage over Company's competitors who do not
                  know or use the Confidential Information or Company
                  Inventions. Protection of the Confidential Information and
                  Company Inventions against unauthorized disclosure and use is
                  of critical importance to Company in maintaining its
                  competitive position. Employee agrees that Employee will not,
                  at any time, during or after the Employment Period, make any
                  independent use of, or disclose to any other person or
                  organization, except as authorized by Company in writing, any
                  Confidential Information or Company Inventions. Upon
                  termination of the Employment Period for any reason, Employee
                  shall promptly deliver to Company all drawings, manuals,
                  letters, notes, notebooks, reports, customer lists, customer
                  data, mailing lists, and all other materials and records of
                  any kind, and all copies thereof, that may be in the
                  possession of, or under the control of, Employee pertaining to
                  Company's business including any that contain any Confidential
                  Information or Company Inventions.

         7.       PERSONNEL POLICIES. Company's personnel policies apply to all
                  of Company's employees including Employee and describe
                  additional terms and conditions of employment of Employee.
                  Those terms and conditions, as they may be revised from time
                  to time by Company, are incorporated by reference into this
                  Employment Agreement. Company reserves the right to revise the
                  personnel policies from time to time, as Company deems
                  necessary. If any personnel policy provision conflicts with a
                  provision of this Employment Agreement, the terms of this
                  Employment Agreement shall govern.

         8.       ALCOHOL AND DRUG TESTING. Employee agrees to comply with and
                  submit to any Company program or policy for testing for
                  alcohol abuse or use of drugs.

         9.       BINDING EFFECT. This Employment Agreement constitutes the
                  entire understanding of the parties, may be modified only in
                  writing, is governed by laws of New Mexico, and will bind and
                  inure to the benefit of Employee and Employee's personal
                  representative and Company and Company's successors and
                  assigns.
