This Consulting Agreement, dated as of July 21, 2000 (the "Agreement"), by and

1-  CONTRACT START DATE

    July 21, 2000.

2-  CONTRACT EXPIRATION DATE

    January 20, 2001, unless terminated in accordance with provisions stated in
    this Contract.

3-  SPECIFIC DUTIES

    EFR agrees to provide the best efforts of Edward F. Rogers ("Consultant") to
    provide advice and counsel on a broad range of subjects as requested by
    Authoriszor's President & CEO ("President") to whom the Consultant will
    report.

    During the term of this Agreement, the EFR and Authoriszor hereby agree that
    the Consultant will have no authority to bind Authoriszor or its
    subsidiaries with regard to any obligation or liability or waive or promise
    of any right or claim of Authoriszor or its subsidiaries in any manner
    whatsoever; and the Consultant shall not perform any executive duties or
    responsibilities, including any decision-making responsibilities with
    respect to the business of Authoriszor.

4-  WORK DAYS

    EFR and Authoriszor agree that the Consultant will spend a minimum of 10
    days per month performing consulting services to Authoriszor. The Consultant
    and the President will meet at the beginning of each month to determine the
    activity and the days required by the Consultant for that month. If they
    both agree that more than 10 days are required to complete the assigned
    tasks,

    Authoriszor will agree to pay for additional days at the agreed upon rate
    per day of $3,000 ($2,000 in cash, $1,000 in restricted stock). The
    President will confirm the monthly days scheduled, if it is more than 10
    days, in writing the same day the meeting is held. If during any month, days
    beyond the agreed to days are required for any reason, Authoriszor and EFR
    must agree to the additional days in writing.

5-  INVOICING

    EFR will invoice Authoriszor on the first business day of each month for
    Consultant's services provided in the prior month.

6-  PAYMENT

    Authoriszor agrees to pay EFR no later than the 10th day of the month the
    invoice is dated.

7-  CASH COMPENSATION

    Authoriszor agrees to pay EFR two thousand dollars ($2,000.00) per day for
    each day of consulting services provided by Consultant, as agreed to by
    Authoriszor and EFR.

8-  RESTRICTED SHARES

    Authoriszor agrees to deliver to EFR in January 2001 the earned shares
    certificate of Authoriszor's common stock with the restriction that these
    shares must not be sold, traded or exchanged, for a period of twelve (12)
    months after the Expiration Date of this contract. In the event that
    Authoriszor has a change in ownership of more than 50% in a single
    transaction or series of transactions, the share restrictions will be lifted
    and these shares will have the same rights as all the common shares. The

    METHOD OF DETERMINING NUMBER OF RESTRICTED SHARES

    The method agreed to by Authoriszor and EFR for the number of restricted
    shares is to establish a value of $1,000 per day times the number of days of
    consulting services provided in each month in order to determine the total
    dollar value per week/month. The per share price for each restricted share
    issued shall be calculated weekly for the days worked in that week and will
    be the last reported sales price of the Authoriszor's common stock on the
    NASDAQ National Market System at the close of business on the last business
    day of the week in the week the Consultant's services were performed.

    CALCULATION

    The number of Restricted Shares can be calculated by multiplying the number
    of consulting service days in the week by $1,000 to determine the total
    restricted value in that week.

    The total restricted value divided by last reported sales price at the close
    of business on the last day of the week the services were performed will
    equal the number of restricted shares for that week.

    Each week, the last business day of which falls in a particular month, can
    then be totaled to arrive at the monthly aggregation and also the total
    contract amount.

    The total aggregate of the Restricted Shares will be delivered to EFR in
    January 2001.

9-  STOCK OPTIONS

    In addition to the Cash Compensation and Restricted Stock, Authoriszor will
    grant to EFR an option to purchase 100,002 shares of common stock of
    Authoriszor. The options will vest on a monthly pro rated basis (i.e. 16,667
    per month) as long as this Agreement is
<PAGE>

Edward F. Rogers

Page 4


    in effect. The options will be exercisable over a three-year period
    commencing on the six-month anniversary of the expiration date of this
    agreement. In the event Authoriszor has a change in ownership of more than
    50% in a single transaction or a series of transactions, the option share
    restrictions will be lifted and the shares will vest and be immediately
    exercisable. The grant of this option is contingent upon execution by the
    Consultant of an investment letter in the form attached hereto as Exhibit B.

    OPTION SHARE PRICE

    The exercise price for the options issued to EFR shall be $7.75 per share,
    the NASDAQ National Market System stock price at the close of business on
    the business day immediately preceding the Start Date of this contract.

10- EXPENSES

    Authoriszor will reimburse EFR for all of the Consultant's reasonable
    business related expenses incurred in the performance of this agreement.
    Authoriszor agrees to pay directly for all of the Consultant's living
    accommodations and provide a $50.00 per day meal allowance when Consultant
    is working in the Burlington, Massachusetts office. In addition, Authoriszor
    will also pay all reasonable related business expenses incurred by
    Consultant in the performance of services for Authoriszor outside of
    Burlington, MA.

11- DATA AND INFORMATION

    obtains or compiles during this Agreement shall be the sole property of
    Authoriszor. The Consultant agrees that all works or authorship that are
    made by the Consultant within the scope of this engagement by Authoriszor

dated as of _______, 2000, by and between the Company and EFR LLC ("EFR") and
the sole member of EFR, Edward F. Rogers ("Rogers," together with EFR, the

with a view to or for resale in connection with any distribution or public
offering thereof, within the meaning of any applicable securities laws and

such registration is available.

4.   The Consultant (i) has received all the information it has deemed necessary
to make an informed investment decision with respect to an acquisition of the
Shares; (ii) understands that the Company is subject to the reporting
requirements of the Securities Exchange Act of 1934, as amended (the "Exchange

          STATEMENT UNDER THE ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION
          UNDER THE SECURITIES ACT, THE AVAILABILITY OF WHICH IS TO BE
          ESTABLISHED TO THE SATISFACTION OF THE COMPANY.

the Company is relying upon the representations made herein as the basis for
your claiming the exemption.

9.   In the event the Shares or any portion thereof are subsequently
transferred, the Consultant agrees to execute, deliver and file all such papers,
documents and instruments as may be required by the SEC and any state securities
commission to qualify the transfer for an exemption from registration under the
Securities Act, or any applicable state securities laws, respectively, to the
extent that such papers, documents and instruments may be necessary or
appropriate for such transfer.  The Consultant agrees to furnish the Company
with a copy of all such papers, documents and instruments, and, in addition,
will furnish the Company with any other information that the Company may
reasonably require to ensure that no subsequent transfer or disposition of the
Shares is in violation of the Securities Act or any applicable state securities
laws.
<PAGE>

10.  The Consultant further acknowledges that it is aware that stop-transfer
instructions shall be given to the transfer agent of the Shares to prevent any
unauthorized or illegal transfer of the Shares.

11.  For purposes hereof, the term resale includes any transfer for value
including the mortgage, pledge, or hypothecation of such Shares.

12.  This investment letter shall be binding upon the Consultant's successors
and assigns and shall inure to the benefit of your successors and assigns.
