      THIS SECURITIES PURCHASE AGREEMENT (this "Agreement"), is made and entered
into by and among Integrated Information Systems, Inc., a Delaware corporation
(the "Company"), and the purchasers named on the attached Schedule A, as the
same may be supplemented from time to time (collectively the "Purchasers" and
each individually a "Purchaser"). With respect to the initial purchase and sale
of Shares hereunder, the effective date of this Agreement shall be April 4,
2003.

                                    RECITALS

      A. The Company wishes to issue and sell to one or more Purchasers up to
200,000 shares (the "Shares") of Series B 12% Convertible Preferred Stock par
value $0.001 per share (the "Preferred Stock"), at a per share purchase price of
$10.00.

      B. Each Purchaser wishes to purchase the Shares on the terms and subject
to the conditions set forth in this Agreement.

                                    AGREEMENT

      NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained in this Agreement and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, and intending to be
legally bound, the parties agree as follows:

      1. Sale of Shares.

            a. Issuance, Sale and Delivery of the Shares. Subject to the terms
and conditions hereof and in reliance upon the representations, warranties,
covenants and agreements contained herein, the Corporation hereby agrees to
issue and sell to the Purchasers, and each Purchaser hereby severally agrees to
purchase from the Corporation at a Closing (as hereinafter defined), the
aggregate number of Shares set forth opposite the name of such Purchaser under
the heading "Number of Preferred Shares" on Schedule A attached hereto. Each
Purchaser's Shares will be convertible into shares of the Company's $0.001 par
value common stock (the "Common Stock") as set forth in the Certificate of
Designation (as hereinafter defined).

            b. Closing. Each sale and purchase of any Shares shall take place at
a closing (each, a "Closing") at the Company's offices in Tempe, Arizona at such
date and time as may be mutually agreed upon by the Company and the Purchasers,
with the first Closing to take place on April 4, 2003 at 10:00 a.m.; provided,
however, that the obligations of the Purchasers hereunder are subject to:

                  (i) The Corporation's filing of a Certificate of Designation
with respect to the Preferred Stock in form and substance reasonably
satisfactory to the Purchasers (the "Certificate of Designation"); and

<PAGE>

                  (ii) The Corporation shall have executed and delivered to the
Purchasers a Registration Rights Agreement, in form and substance reasonably
satisfactory to the Purchasers (the "Registration Rights Agreement").

            c. Deliveries at Closing. Upon a purchase of Shares at a Closing,
the Corporation shall issue and deliver to each Purchaser a stock certificate
evidencing the Shares purchased at the Closing. As payment in full for the
Shares being purchased by it at the Closing, and against delivery of the
certificates for the Shares, each Purchaser shall deliver to the Corporation, by
official check or wire transfer, the "Aggregate Subscription Price" amount set
forth opposite the Purchaser's name on Schedule A. In addition to the initial
purchase of Shares hereunder, the Corporation and the purchaser identified on
Schedule A have agreed, at the Closing for such initial purchase and in
consideration for such purchaser agreeing to purchase Shares hereunder, to
exchange 40,000 shares of the Corporation's Series A 8% Convertible Preferred
Stock for 40,000 Shares of the Preferred Stock.

      2. Representations and Warranties of the Corporation. The Corporation
hereby represents and warrants to each Purchaser as follows:

authority to execute and deliver this Agreement, to perform all its obligations
hereunder, to issue, sell and deliver the Shares, and to issue and deliver the
shares of Common Stock issuable upon conversion of the Shares (the "Conversion
Shares").

            b. Authorization of Agreements and Validity.

                  (i) The execution and delivery by the Corporation of this
Agreement, the performance by the Corporation of its obligations hereunder, the
issuance, sale and delivery of the Shares and the issuance and delivery of the
Conversion Shares shall, prior to the Closing, be duly authorized by all
requisite corporate action and will not (x) violate (i) any provision of any

of the SEC with respect thereto, have been prepared in accordance with generally
accounting principles applied on a consistent basis during the periods involved
(except as may be indicated in the notes thereto or, in the case of the
unaudited statements, as permitted by Rule 10-01 of Regulation S-X promulgated
by the SEC) and fairly present (subject, in the case of the unaudited
statements, to normal, recurring audit adjustments, none of which will be
material) the consolidated financial position of the Corporation and its
consolidated subsidiaries as of the dates thereof and the consolidated results
of their operations and cash flows for the periods then ended.

severally represents and warrants to the Corporation that:

            a. the Purchaser is an "accredited investor" within the meaning of
Rule 501 of Regulation D under the Securities Act of 1933, as amended (the
"Securities Act");

            b. the Purchaser has sufficient knowledge and experience in
investing in companies similar to the Corporation so as to be able to evaluate
the risks and merits of its investment in the Corporation and it is able
financially to bear the risks thereof;

            c. the Shares and Conversion Shares being purchased by the Purchaser
are being acquired for the Purchaser's own account for the purpose of
investment;

            d. the Purchaser understands that (i) the Shares and the Conversion
Shares have not been registered under the Securities Act by reason of their
issuance in a transaction exempt from the registration requirements of the
Securities Act pursuant to Section 4(2) thereof or Rule 506 promulgated under
the Securities Act, (ii) the Shares and the Conversion Shares must be held
indefinitely unless a subsequent disposition thereof is registered under the
Securities Act or is exempt from such registration, (iii) the Shares and the
Conversion Shares will bear a legend to such effect, and (iv) the Corporation
will make a notation on its transfer books to such effect;

            e. no person has or will have, as a result of the transactions
contemplated by this Agreement, any right, interest or valid claim against or
upon the Corporation for any commission, fee or other compensation as a finder

      4. Covenants.

            a. Reservation of Conversion Shares. The Corporation shall at all
times reserve and keep available out of its authorized but unissued shares of
Common Stock, for the purpose of effecting the conversion of the Shares, such
number of its duly authorized shares of Common Stock as shall be sufficient to
effect the conversion of the Shares from time to time outstanding. If at any
time the number of authorized but unissued shares of Common Stock shall not be
sufficient to effect the conversion of the Shares, the Corporation will
forthwith take such corporate action as may be necessary to increase its
authorized but unissued shares of Common Stock to such number of shares as shall
be sufficient for such purposes. The Corporation will use reasonable efforts to
obtain any authorization, consent, approval or other action by or make any
filing with any court or administrative body that may be required under
applicable state securities laws in connection with the issuance of shares of
Common Stock upon conversion of the Shares. Without limiting the generality of
the foregoing, in the event that the number of Conversion Shares issuable upon
conversion of the Preferred Stock would exceed 19.99% of the Common Stock issued
and outstanding at the date of the first sale of Preferred Stock, a majority in
interest of the Purchasers may request, by delivering written notice to the
Corporation, that the Corporation call a special meeting of its stockholders to
approve the Corporation's issuance of the full number of Conversion Shares in
order that such issuance will comply with Marketplace Rule 4350(i) of The Nasdaq
Stock Market. Upon receipt of such request, the Corporation agrees to promptly
call such special meeting of its stockholders, and in connection therewith, to
promptly file a preliminary proxy statement with the Securities and Exchange
Commission and otherwise use all reasonable commercial efforts to obtain such
stockholder approval; provided, however, that the Purchasers shall not be
entitled to deliver a call for such a meeting for a period of one year after the
initial sale of Shares under this Agreement and that previously issued
Conversion Shares shall not be eligible to vote on the proposal.

            b. Registration Rights. The Corporation and the Purchasers shall
promptly negotiate in good faith, execute and deliver a registration rights
agreement in order to provide the Purchasers with "piggyback" registration
rights with respect to the sale of the Conversion Shares in two registrations,
with the Corporation paying the costs of the Purchasers for such registrations.

            c. Further Assurances. Prior to and following the Closing, the
Corporation and the Purchasers shall execute and deliver such documents, and
take such other action, as shall be reasonably requested by any other party
hereto to carry out the transactions contemplated by this Agreement.

      5. Miscellaneous.

            a. Expenses. Each party hereto will pay its own expenses in
connection with the transactions contemplated hereby.

            b. Brokerage. Each party hereto will indemnify and hold harmless the
others against and in respect of any claim for brokerage or other commissions
relative to this Agreement or to the transactions contemplated hereby, based in
any way on agreements,


                                       5
<PAGE>

arrangements or understandings made or claimed to have been made by such party
with any third party.

            c. Governing Law. This Agreement shall be governed by and construed
in accordance with the laws of the State of Arizona for all purposes and in all
respects, without regard to the conflict of law provisions of such state.

            d. Entire Agreement. This Agreement, the Registration Rights
Agreement and the Certificate of Designation constitute the sole and entire
agreement of the parties with respect to the subject matter hereof. Any exhibits
or schedules hereto or thereto are hereby incorporated herein by reference.

            e. Counterparts. This Agreement may be executed in counterparts,
each of which shall be deemed an original, but all of which together shall
constitute the same instrument. The Purchasers acknowledge that the Corporation
intends to offer shares of the Preferred Stock in a "minimum - maximum" private
placement, with a minimum of $200,000 and a maximum of $2,000,000 and that the
Corporation may take the purchase price directly into its operating accounts,
rather than placing funds in escrow, once the minimum has been satisfied. After
the first Closing, a Purchaser shall join in this Agreement by executing a
signature page hereto, will be deemed to have joined in this Agreement only as
of the date such signature page was executed, and such Purchaser shall deliver
the purchase price funds against delivery of the purchased Shares at a Closing
held in the manner set forth in Section 1.b, above. With each subsequent
purchase, the Corporation shall amend Schedule A and send the amended schedule
to each of the previous Purchasers.

            f. Amendments and Waivers. This Agreement may be amended or
modified, and provisions hereof may be waived, with the written consent of the
Corporation and the Purchasers.

            g. Titles and Subtitles. The titles and subtitles used in this
Agreement are for convenience only and are not to be considered in construing or
interpreting any term or provision of this Agreement.


      IN WITNESS WHEREOF, the Corporation and the Purchasers have executed this
Stock Purchase Agreement as of the date first above written.
