                                 LOAN AGREEMENT

      This Agreement is made and entered into this 4th day of April, 2003, by
and between Integrated Information Systems, Inc., a Delaware corporation (the
"Borrower"), and AnchorBank, fsb (the "Lender").

      In consideration of the mutual agreements herein contained, the Borrower
and the Lender hereby agree as follows:

                                    ARTICLE 1

                              LOAN AND MASTER NOTE

      1.1 Revolving Credit Facility; Master Note. Subject to the terms of this
Agreement, the Borrower may borrow from the Lender the sum of One Million and
no/100 Dollars ($1,000,000.00) (the "Credit Facility"). The Borrower shall not
exceed the loan limit set forth herein. In the event that any excess shall
occur, the Borrower shall immediately, without request, prepay outstanding loans
hereunder in an amount sufficient to eliminate such excess. The Credit Facility
availability under this Section shall be evidenced by a revolving credit note of
the Borrower payable to the order of the Lender in the principal amount of One
Million and no/100 Dollars ($1,000,000.00) dated as of the date hereof, in
substantially the form of Exhibit A attached hereto (the "Master Note"). The
Master Note shall be executed by the Borrower and delivered to the Lender prior
to the initial loan hereunder.

      1.2 Purpose. The purpose of the Credit Facility is to provide financing
for Borrower's operations.

      1.3 Borrowing Limits. The Master Note will evidence the total Credit
Facility availability that may be borrowed, repaid and reborrowed, subject to
the terms set forth herein. Although the Master Note shall be expressed to be
payable in the full amount of the commitment set forth herein, the Borrower
shall be obligated to pay only the amounts actually disbursed to the Borrower
hereunder, together with accrued interest on the outstanding balance thereof at
the rates and on the dates specified therein and such other charges provided for
herein.

                                   ARTICLE 2

                                   ARTICLE 3

                         REPRESENTATIONS AND WARRANTIES

      In order to induce the Lender to provide the Credit Facility as herein
provided, the Borrower represents and warrants to the Lender as follows on the
date hereof and on the date each Loan is made:

      3.1 Organization. The Borrower is a corporation duly organized under the
laws of the state of Delaware and has all requisite power and authority, to
conduct its business and to own its properties. The Borrower is duly qualified
to do business in all jurisdictions in which the Borrower has substantial
property or business operations.

      3.2 Authority. The execution, delivery and performance of this Agreement,
the Master Note and the Loan Documents are within the power of the Borrower,
have been duly authorized by all necessary action and do not and will not: (i)
require any consent or approval of any member of the Borrower (other than such
consents as have already been obtained); (ii) violate any provision of the
Certificate of Incorporation and Bylaws of the Borrower or of any law, rule,
regulation, order, writ, judgment, injunction, decree, determination or award
presently in effect having applicability to the Borrower; (iii) require the
consent or approval of, or filing or registration with, any governmental body,
agency or authority; or (iv) result in a breach of or constitute a default
under, or result in the imposition of any lien, charge or encumbrance upon any
property of the Borrower pursuant to any indenture or other agreement or
instrument under which the Borrower is a party, or by which it or its properties
may be bound or affected. This Agreement and the Loan Documents each constitute,
and the Loan Documents when delivered hereunder will constitute, legal, valid
and binding obligations of the Borrower enforceable against the Borrower in
accordance with their respective terms, except as enforceability may be limited
by applicable bankruptcy, insolvency, reorganization or similar laws affecting
the rights of creditors generally.

      3.3 Investment Company Act of 1940. The Borrower is not an "investment
company" or a company "controlled" by an "investment company" within the meaning
of the Investment Company Act of 1940, as amended.

      3.4 Lending Business. The Borrower is not engaged principally, or as one
of its important activities, in the business of extending credit for the purpose
of "purchasing" or "carrying" any "margin stock" (all as defined in Regulation U
of the Board of Governors of the Federal Reserve System, as amended from time to
time).

      3.5 Financial Statements. The financial statements of Borrower and
Guarantor as prepared and heretofore furnished to the Lender are correct and
complete and truly represent the financial condition of the Borrower and
Guarantor as of the date specified thereon and there has been no change in the
property, financial condition or business operations of the Borrower or
Guarantor which has had or will have a material adverse affect on the Borrower
or the Guarantor, as the case may be.

      3.6 Liens. The Borrower has good and indefeasible title to all of the
personal property subject to the Security Agreement, free and clear of all
liens, security interests, and encumbrances of any kind except for the lien of
Lender, and for the Permitted Liens, set forth on Schedule 3.6 hereto. All owned
and leased equipment and leased real property of the Borrower are in good
condition, repair, and working order,

                                       3
                                                                   April 4, 2003

ordinary wear and tear excepted, and, to the best of Borrower's knowledge and
belief, conform to all applicable laws, regulations, and ordinances.

      3.7 Contingent Liabilities. The Borrower has no guarantees or other
contingent liabilities outstanding, except those permitted by Section 4.2
hereof.

      3.8 Taxes. The Borrower has no material outstanding unpaid tax liability
(except for taxes which are currently accruing from current operations and
ownership of property, which are not delinquent), and no tax deficiencies have
been proposed or assessed against the Borrower, other than taxes included on
Schedule 3.10 which Borrower, acting in good faith, contests and shall take the
appropriate actions and proceedings to have discharged or paid.

      3.9 Absence of Litigation. Neither the Borrower nor Guarantor is a party
to any litigation or administrative proceeding, nor so far as is known by the
Borrower or Guarantor is any litigation or administrative proceeding threatened
against it or him, (i) which relates to the execution, delivery or performance
of this Agreement, the Note or any Loan Document, or (ii) which would, if
adversely determined, cause any material adverse change in the property,
financial condition or business operations of the Borrower or Guarantor, except
as set forth on Schedule 3.9 hereto.

      3.10 Absence of Default. No event has occurred which either of itself or
with the lapse of time or the giving of notice or both, would give any creditor
of the Borrower or any Guarantor the right to accelerate the maturity of any
indebtedness of the Borrower for borrowed money, except as set forth on Schedule
3.10 hereto. The Borrower is not in default under any lease, agreement or
instrument, or any law, rule, regulation, order, writ, injunction, decree,
determination or award, non-compliance with which would materially adversely
affect its property, financial condition or business operations, except as set
forth on Schedule 3.10 hereto.

      3.11 No Burdensome Agreements. Except as set forth on Schedule 3.11
hereto, the Borrower is not a party to any agreement, instrument or undertaking,
or subject to any other restriction, (i) which materially adversely affects or
to the best knowledge of Borrower, may in the future so affect the property,
financial condition or business operations of the Borrower, or (ii) under or
pursuant to which the Borrower is or will be required to place (or under which
any other person may place) a lien upon any of its properties securing
indebtedness either upon demand or upon the happening of a condition, with or
without such demand.

      3.12 Full Disclosure. No information, exhibit or report furnished by
Borrower or Guarantor to the Lender in connection with the negotiation or
execution of this Agreement contained any material misstatement of fact as of
the date when made or omitted to state a material fact or any fact necessary to
make the statements contained therein not materially misleading as of the date
when made.

      3.13 Environmental Matters. Borrower shall (a) at all times comply in all
material respects with all applicable Environmental Laws and (b) promptly take
any and all necessary remedial actions in response to the presence, storage,
use, disposal, transportation, or Release of any Hazardous Materials on, under,
or about any real property owned, leased, or operated by Borrower. In the event
that Borrower undertakes any remedial action with respect to any Hazardous
Material on, under, or about any real property, Borrower shall conduct and
complete such remedial action in compliance with all applicable Environmental
Laws and in accordance with the policies, orders, and directives of all federal,
state, and local governmental authorities, except when such Borrower's liability
for such presence, storage, use, disposal, transportation, or Release of any
Hazardous Material is being contested in good faith by such Borrower and
appropriate reserves therefore have been established. If Lender at any time has
a reasonable basis to believe that there may be a material violation of any
Environmental Law by Borrower, or any material liability arising thereunder or
related to a Release of Hazardous Materials on any real property owned, leased,
or operated by Borrower or a Release on real property adjacent to such real
property, then Borrower shall, upon the request of Lender, provide Lender with
all such reports, certificates, engineering studies, and other written material
or dates relating thereto as Lender may reasonably require.

                                                                   April 4, 2003

                               NEGATIVE COVENANTS

      While any part of the principal of or interest on the Master Note remains
unpaid, the Borrower shall not do any of the following, without the prior
written consent of the Lender:

      4.1 Judgments and Settlements of Borrower. Have a judgment or judgments
taken against it or enter into a settlement or settlements resolving the
disputes, which judgment(s) and settlement(s) (excluding any settlement with MCW
Brickyard Commercial, LLC) exceed Two Hundred Fifty Thousand and no/100 Dollars
($250,000.00) in the aggregate in any of Borrower's fiscal years.

      4.2 Contingent Liabilities. Guarantee or become a surety or otherwise
contingently liable (including, without limitation, liable by way of agreement,
contingent or otherwise, to purchase, or provide funds for payment, to supply
funds to or otherwise invest in the debtor or otherwise to assure the creditor
against loss) for any obligations of others, except pursuant to the deposit and
collection of checks and similar items in the ordinary course of business.

      4.3 Affiliates. Suffer or permit any transaction with any affiliate of
Borrower, except on terms not less favorable than would be usual and customary
in similar transactions with non-affiliated persons.

      4.4 Restrictions on Liens. Create or permit to be created or allowed to
exist any mortgage, pledge, encumbrance or other lien upon or security interest
in any property or assets now owned or hereafter acquired by the Borrower,
except Permitted Liens.

                                   ARTICLE 5

                              AFFIRMATIVE COVENANTS

maintain corporate existence, and all rights and franchises necessary or
desirable for the conduct of its business; (ii) comply with all applicable laws,
rules, regulations and ordinances, and all restrictions imposed by governmental
authorities, including those relating to environmental standards and controls;
and (iii) pay, before the same become delinquent and before penalties accrue
thereon, all taxes, assessments and other governmental charges against it or its
property, and all of its other liabilities, except to the extent and so long as
the same are being contested in good faith by appropriate proceedings in such
manner as not to cause any material adverse effect upon its property, financial
condition or business operations, with adequate reserves as determined in the
reasonable discretion of Borrower provided for such payments.

      5.2 Business Activities. Continue to carry on its business activities in
substantially the manner such activities are conducted on the date of this
Agreement and not make any material change in the nature of its business.

      5.3 Properties. Keep its properties (whether owned or leased) in good
condition, repair and working order, ordinary wear and tear and obsolescence
excepted, and make or cause to be made from time to time all necessary repairs

                                    DEFAULTS

      In the event that any one or more of the following events shall occur
(following the giving of any required notice, and the expiration of any required
cure period, each such event is referred to herein as an "Event of Default"):

      6.1 Default Under the Master Note. A default shall occur under the terms
of the Master Note or any other obligation owed by Borrower to Lender, whether
now or at any time hereafter existing, including but not limited to the Revised
and Restated Subordinated Note and obligations under the Business Manager
Agreement(R) and their related loan documents and the same shall continue for
ten (10) days after Lender gives written notice thereof to Borrower, except that
no notice of a payment default shall be required to be provided to Borrower.

      6.2 Default on Negative Covenants. Default by Borrower in the performance
or observance of any agreement, covenant, condition, provision or term contained
in Article 4 of this Agreement and the same shall continue for thirty (30) days

Guarantor in the performance or observance of any of the other agreements,
covenants, conditions, provisions or terms in this Agreement, the Loan
Documents, any other instrument or document evidencing or securing the Credit

security for any of Borrower's obligations to Lender, including, without
limitation, that General Business Security Agreement of even date herewith given
by Borrower to Lender.

      6.4 Representations or Statements False. Any representation or warranty
made by the Borrower or the Guarantor in any certificate or credit or security

any part of the principal of or interest on any indebtedness of or assumed by it
as and when due and payable (whether by fixed maturity or acceleration) or of
the rentals due under any lease or sub-lease, and such default shall not be
cured within the period or periods of grace, if any, specified in the
instruments governing such obligations; or default shall occur under any
evidence of, or any indenture, lease, sub-lease agreement or other instrument
governing, such obligation, and such default shall continue for a period of time
sufficient to permit the acceleration of the maturity of any such indebtedness
or the termination of such lease or sub-lease, except those obligations set
forth in Schedule 6.5 hereto.

      6.6 Validity. This Agreement, the Master Note, or any document required by
Article 2 shall, at any time after their respective execution and delivery, and
for any reason, cease to be in full force and effect or shall be declared null
and void, or be revoked or terminated, or the validity or enforceability thereof
or hereof shall be contested by the Borrower, Guarantor, or the Borrower or
Guarantor shall deny that it has any or further liability or obligation
thereunder or hereunder, as the case may be.

      (a)   As to any event of default under Section 6.1, 6.2, 6.3, 6.4, 6.5, or
            6.6, the Lender may immediately terminate its obligation to make any
            advances hereunder and/or declare the unpaid principal balance of
            the Master Note, together with all interest accrued thereon, to be
            immediately due and payable; and the unpaid principal balance of and
            accrued interest on the Master Note shall thereupon be due and
            payable all without presentment, demand, protest, or notice of any

            the imposition of a different rate of interest after maturity as set
            forth in such note.

                          REVOLVING CREDIT MASTER NOTE

$1,000,000.00                                                 Madison, Wisconsin
                                                                   April 4, 2003

      FOR VALUE RECEIVED, Integrated Information Systems, Inc., a Delaware
corporation (the "Borrower"), promises to pay to the order of AnchorBank, fsb
("Lender"), or the holder hereof, the principal sum of One Million and no/100
Dollars ($1,000,000.00), together with interest on the unpaid principal balance
from the date hereof, until paid, at the Prime Rate, per annum. As used herein,
the term "Prime Rate" shall mean the rate of interest used from time to time by
Lender as its prime rate for interest rate determinations. Borrower is advised
that the Prime Rate may not be the lowest rate of interest available to
customers of Lender. The rate of interest hereunder shall change on the first
(1st) day of each month to equal the Prime Rate then in effect, per annum.
Notwithstanding the foregoing, at no time during the term of this Note shall the
rate of interest hereunder be less than Five and Three-quarters Percent (5.75%),
per annum. Interest shall be calculated on the basis of the actual number of
days elapsed over a 360-day year. Disbursement of the proceeds of this Note
shall be made pursuant to the terms of that certain Revolving Credit Loan
Agreement of even date herewith executed by and between Lender and Borrower (the
"Loan Agreement"). Amounts under this Note may be borrowed, repaid, and
reborrowed during the term of this Note, on the terms set forth in the Loan
Agreement, provided no default exists hereunder or under the terms of any loan
documents between Lender and Borrower. All payments by Borrower shall be made in
lawful currency of the United States and in immediately available funds. Prior
to any default hereunder, Lender agrees to accept payment by check. Payments
hereunder shall be applied first to the payment of interest with the balance, if
any, to principal. The payment of the principal and interest hereunder shall be
due and payable at 25 West Main Street, Madison, Wisconsin 53703, or such other
place as Lender may designate, in writing, as follows:

1.    Commencing on the first (1st) day of the month following the date of this
      Note, and continuing thereafter on the first (1st) day of each month until
      the Maturity Date, Borrower shall make payments of interest only on the
      disbursed and outstanding principal balance hereunder.

2.    Unless sooner paid, the unpaid principal balance and all accrued interest
      thereon shall be paid in full on the first (1st) annual anniversary date
      of the date hereof (the "Maturity Date").

      If any installment under this Note is not received by Lender within ten
(10) calendar days after the installment is due, the undersigned shall pay to
the holder a late charge of Five Percent (5%) of such installment, such late
charge to be immediately due and payable without demand by Lender.

      If (i) Borrower fails to pay any installment of principal and/or interest
due hereunder as and when due, and such default continues for ten (10) days; or
(ii) an Event of Default shall occur under the Loan Agreement, Security
Agreements, or other loan documents between Borrower and Lender, and such Event
of Default is not cured within applicable cure periods, if any, then the entire
unpaid principal balance, plus accrued interest, shall, at the option of the
holder hereof and without notice, which is hereby expressly waived, mature and
be immediately due and payable. Failure to exercise this option following any
event above shall not constitute a waiver of the right to exercise the same at a
later time or upon the occurrence of any such subsequent event or events. During
any period in which Borrower is in default hereunder, this Note shall bear
interest at the rate of Five Percent (5%) per annum in excess of the Note rate
in effect immediately prior to the default from the date of such default until
such default is cured, or, if acceleration has occurred, until this Note has
been paid; provided, however, that such rate shall not exceed the highest rate
permitted by law; and further provided, that the default rate shall change with
each change in the interest rate under this Note as set forth above.

<PAGE>

      During the term of this Note, Borrower may prepay all or any part of the
principal balance hereunder without penalty or fee. Prepayments shall be applied
against the outstanding principal balance of this Note and shall not extend or
postpone the due date of any subsequent monthly installments or change the
amount of such installments, unless Lender shall agree otherwise in writing. As
used herein, the term prepayment shall include all voluntary payments and all
payments occurring as a result of the acceleration by Lender of the principal
amount of this Note but shall not include payments occurring because of the
application by Lender of insurance proceeds or condemnation awards to the
indebtedness evidenced hereby.

      From time to time, without affecting the obligation of the Borrower or the
successors or assigns of the Borrower to pay the outstanding principal balance
of this Note and observe the covenants of the Borrower contained herein, without
affecting the guarantee of any person, corporation, partnership or other entity
for payment of the outstanding principal balance of this Note, without giving
notice to or obtaining the consent of the Borrower, the successors or assigns of
the Borrower or guarantors, and without liability on the part of Lender, Lender
may, at its option, extend the time for payment of said outstanding principal
balance or any part thereof, reduce the payments thereon, release anyone liable
on any of said outstanding principal balance, accept a renewal of this Note,
modify the terms and time of payment of said outstanding principal balance, join
in any extension or subordination agreement, release any security given herefor,
take or release other or additional security, and agree in writing with the
Borrower, its successors or assigns, to modify the rate of interest or period of
amortization of this Note.

      Borrower and all others who may become liable for all or any part of this
obligation, agree hereby to be jointly and severally bound, and jointly and
severally waive and renounce presentment, protest, demand and notice of
presentment, notice of protest, notice of non-payment of the Note, notice of
dishonor and each and every other notice of any kind respecting this Note.
Borrower and all others who may become liable hereunder waive all lack of
diligence or delays in collection or endorsement hereof.

      Nothing contained herein nor in any transaction related hereto shall be
construed or shall so operate either presently or prospectively (a) to require
the payment of interest at a rate greater than is now lawful in such case to
contract for, but shall require payment of interest only to the extent of such
lawful rate, or (b) to require the payment or the doing of any act contrary to
law; but if any clause or provision herein contained shall otherwise so operate
to invalidate this Note and/or the transaction related hereto, in whole or in
part, then such clause(s) and provision(s) only shall be held for naught as
though not contained herein and the remainder of this Note shall remain
operative and in full force and effect.

      If for any reason interest in excess of the amount as limited in the
foregoing paragraph shall have been paid hereunder, whether by reason of
acceleration or otherwise, then in that event any such excess interest shall
constitute and be treated as a payment of principal hereunder and shall operate
to reduce such principal by the amount of such excess, or if in excess of the
principal indebtedness, such excess shall be refunded.

      This Note is secured by various assignments and agreements given by
Borrower to Lender as provided in the Loan Agreement (the "Security Documents")
and by various assignments and agreements previously provided by Borrower to
Lender.

      All of the covenants herein contained are joint and several and shall also
bind, and the benefits hereof shall also inure to, the respective successors and
permitted assigns of the parties hereto. Whenever used, the singular shall
include

<PAGE>

the plural, the plural the singular, and the use of any gender shall include all
genders. The term "Lender" shall include all subsequent holders of this Note.
This Note may be modified only in a writing executed by the Borrower and Lender.

      Borrower agrees that whenever this Note is placed in the hands of an
attorney for collection or to defend or enforce any of Lender's rights
hereunder, the undersigned shall pay to Lender its attorneys' fees, together
with all costs and other expenses incurred or paid Lender in connection
therewith including, without limitation, all pre-judgment and post-judgment
costs and expenses, including attorneys' fees.

      This Note and the Security Documents have all been negotiated and executed
in the State of Wisconsin. Accordingly, it is the intention of the parties that
this Note be governed by the laws of the State of Wisconsin.

      IN WITNESS WHEREOF, the Borrower has caused this Note to be executed in
Madison, Wisconsin as of the date first above written.
