               MASTER AGREEMENT FOR TREASURY MANAGEMENT SERVICES

This Master Agreement for Treasury Management Services ("Agreement") is entered
into this 11th day of June, 1999, between NORWEST BANK IOWA, NATIONAL
ASSOCIATION, (the "Bank") and the undersigned customer AEGlS Mortgage
Acceleration Corp (the "Company").

The Bank offers and provides certain treasury management services to its
commercial customers, and the Company anticipates that it will from time to time
engage the Bank to perform all or some treasury management services under this
Agreement (the "Services").

The Bank and the Company agree:

1.   Scope of the Services.  The Bank shall provide the Company with the
     ---------------------
     treasury management services requested in writing and Services agreed to by
     the Bank. The Services are described in general terms in separate writings
     which are specifically incorporated into this Agreement (the "Product
     Descriptions"). The Company agrees to the terms and conditions contained in
     the applicable Product Description(s); the Bank's user guide (the "Guide"),
     if any, for each Service it requests; and the Bank's terms and conditions
     applicable to each account affected by the Services (the "Account Terms").
     Delivery and use of a Service shall be conclusively deemed to be agreement
     to the provisions contained in the applicable Product Description and
     Guide. The Bank may amend a Product Description, a Guide, or the Account
     Terms from time to time upon fourteen (14) days prior written notice. The
     Company acknowledges receiving a copy of the Account Terms and of the
     Product Description and Guide, if any, for the Services it has initially
     requested.

2.   Performance of the Services.  The Bank shall perform the Services in
     ---------------------------
     accordance with reasonable commercial standards applicable to the Bank's
     business; in conformity with rules, regulations or laws governing the
     activities of the Bank; and in accordance with this Agreement.

3.   Term.  This Agreement shall continue in effect unless terminated by either
     ----
     party upon seven (7) days prior written notice. The Bank may immediately
     terminate this Agreement without notice to the Company if the Company
     files, or has filed against it, a petition under the U.S. Bankruptcy Code
     or a similar state or federal law. Each additional Service shall commence
     within a reasonable time after the Bank agrees to provide it and shall
     continue in effect until terminated by written notice or termination of
     this Agreement.

4.   Service Fees: Taxes; Invoice; Payment.  The Company agrees to pay the Bank
     -------------------------------------
     for the Services in accordance with the Bank's fee schedule(s). The Bank
     may



                                                                         Page 1
<PAGE>

     modify its fee schedule(s) at any time upon prior notice. The Company
     also agrees to pay an amount equal to any taxes applicable to the Services,
     however designated, exclusive of taxes based on the net income of the Bank.
     Except as otherwise agreed in writing, all fees and taxes shall be charged
     monthly against the Company's accrued earnings allowance. The Bank may
     debit the Company's account(s) with the Bank for, or may bill the Company
     and the Company agrees promptly to pay, any amount by which the fees or
     taxes exceed such earnings allowance.

5.   Liability: Indemnification.  The Bank shall be responsible only for
     --------------------------
     performing the Services as expressly provided for in this Agreement, and
     shall be liable only for material losses directly resulting solely from its
     own negligence or intentional misconduct in performing those Services.
     Neither the Bank nor the Company shall have any liability for failure to
     perform or delay in performing the Services if such failure or delay is due
     to circumstances beyond that party's reasonable control. Each party agrees
     to make reasonable efforts to prevent such occurrences. In no event shall
     the Bank have any liability for any consequential, special, punitive or
     indirect loss or damage. The Company shall promptly furnish proof of loss
     in written form to the Bank, and shall provide the Bank all reasonable
     assistance in recovering a loss. If the Company is reimbursed by or on
     behalf of the Bank, the Bank or its designee shall be subrogated to all
     rights of the Company. Except to the extent that the Bank is liable under
     the terms of this Agreement, the Company agrees to indemnify and hold the
     Bank, its directors, officers, employees and agents harmless from all
     claims, demands, judgments, and expenses (including their reasonable
     attorneys' fees and legal expenses) arising out of or in any way connected
     with the performance of the Services. The Company agrees that this
     indemnification shall survive termination of this Agreement.

6.   Affiliates.  Present and future Bank affiliates may from time to time
     ----------
     provide one or more Services under the terms of this Agreement. In that
     event, the Bank shall notify the Company that the affiliate has agreed to
     provide the Service(s), the term "Bank" shall include the affiliate with
     respect to the Service, the Bank and the affiliate may share any
     information helpful in providing the Service and liability with respect to
     the Service shall be limited solely to the affiliate(s) providing the
     Service. The Company acknowledges that its consent to the release of
     information is not a condition of doing business with the Bank or its
     affiliates.

7.   General.  The laws of the state in which the principal office of the
     -------
     particular Bank providing the Service is located shall govern for all
     purposes. This Agreement shall constitute the entire agreement between the
     Bank and the Company and supersede prior oral or written representations,
     conditions, warranties, understandings, proposals or agreements regarding
     the Services. Headings do not constitute a part of this Agreement. Any
     notice or other communication may be



                                                                          Page 2
<PAGE>

     sent to the Company at its then current address on file with the Bank. The
     Bank will have a reasonable time after receipt of any notice or other
     communication to act on it. No provision may be modified except in writing
     signed by the party against whom the modification is to be enforced. No
     waiver of any right on one occasion will be a waiver of the same or any
     other right on a subsequent occasion. The Bank or the Company may assign
     this Agreement to any successor by merger, consolidation or corporate
     reorganization. Any invalidity, in whole or in part, of any provision shall
     not affect the validity of any other provision. The Bank may, grant credit
     to the Company in connection with the Services, but is not required to do
     so. Delivery and use of an informational Service occurs when the
     information is provided. The Bank may, without notice, refuse to honor any
     payment, transfer or withdrawal order which would result in an overdraft,
     even if it has previously allowed overdrafts. The Bank may establish cut-
     off times, and may change those cut-off times upon reasonable notice to the
     Company. Unless specifically defined in the applicable Product Description
     or Guide, the term "banking day" means that part of a business day
     occurring prior to the cut off time stated in the Bank's funds availability
     policy, and the term "business day" means that part of every calendar day
     except Saturdays, Sundays and federal holidays, during which the Bank is
     open to the public for carrying on substantially all of its banking
     functions. The Bank may disclose any information which in its opinion
     facilitates the performance of a Service. The Bank may at any time use
     agents and/or independent contractors to provide all or any portion of a
     Service.

The parties have caused this Agreement to be executed and warrant that their
respective signatory, whose signature(s) appears below, has been and is on the
date of this Agreement duly authorized by all necessary action in accordance
with its governing instruments to execute this Agreement.

                 SECURITY PROCEDURE AGREEMENT FOR ACH SERVICE

This Security Procedure Agreement for ACH Service (the 'Agreement') is entered
into this 11th day of June, 1999 between NORWEST BANK IOWA, NATIONAL ASSOCIATION
(the "Bank") and the undersigned customer AEGIS Mortgage Acceleration Corp. (the
"Company").

The Bank and the Company have entered into a Master Agreement for Treasury
Management Services*, supplemented by a Product Description which governs the
ACH Service to be provided by the Bank.

The Bank and the Company agree:

1.   Security Procedure Selection.  The Company acknowledges that the Bank
     ----------------------------
     offers each of the security procedures described below for the purpose of
     verifying the authenticity of an instruction to originate an ACH electronic
     credit or debit entry (a "payment order") received by the Bank in the name
     of the Company. The Company refuses to have its payment orders verified by
     any security procedure other than the security procedure it has expressly
     designated. The Company has reviewed each of these security procedures and
     has determined that the following security procedure best meets its
     requirements, given the size, type and frequency of the payment orders it
     will issue to the Bank (check one):

     PI    SecurID - File Transmission - This procedure combines a card with a
           ---------------------------
           personal identification number (PIN) known only by the Company and
           the Bank. The card generates a random and unique security code every
           minute. The code combines with the PIN to provide a unique password
           every minute. The password must be presented with the ACH
           transmission and is used by the Bank to authenticate the identity of
           the Company.

     (TM)  Password - File Transmission - This procedure requires that a
           ----------------------------
           unique eight digit code seperately agreed upon in writing by the
           Company and the Bank be presented with the Company's ACH file. The
           Company may be required to change the code on a regular basis.

     (TM)  Password - Taped or Written Instructions - This procedure requires
           ----------------------------------------
           that the Company present taped or written instructions in a tamper
           proof container accompanied by a unique code seperately agreed upon
           in writing by the Company and the Bank.

Services. This document is incorporated under the Master Agreement for Cash
Management Services if one is already on file with Norwest.

                                                                          Page 1
<PAGE>

2.   Security Procedure Protection.  The Company and the Bank will preserve the
     -----------------------------
     confidentiality of the security procedure. If the Company becomes aware of
     a breach, or suspects that a breach may occur, it will immediately notify
     the Bank in a manner affording the Bank a reasonable opportunity to act on
     the information.

3.   Company Bound by Payment Orders.  The Company will be bound by any payment
     -------------------------------
     order, whether or not authorized, issued in its name and accepted by the
     Bank in compliance with the chosen security procedure.

4.   Inconsistency of Name and Number.  If a payment order describes (a) the
     --------------------------------
     receiver inconsistently by name and account number, payment may be made on
     the basis of the account number even if it identifies a person different
     from the named receiver, or (b) a participating financial institution
     inconsistently by name and identification number, the identification number
     may be relied upon as the proper identification of the financial
     institution.

The undersigned have caused this Agreement to be executed and warrant that their
respective signatory, whose signature(s) appears below, has been and is on date
of this Agreement date duly authorized by all necessary action in accordance
with its governing instruments to execute this Agreement.

                SUBLICENSE AGREEMENT FOR BANKTIES(R) ACH SERVICE

This Agreement is entered into this 11th day of June, 1999, ("Effective Date"),
by and between Norwest Bank Iowa, National Association, (the "Bank") and AEGIS

                                    RECITALS

WHEREAS, the Bank has sublicensed a certain software package from Politzer &
Haney ("P&H") entitled Auto Cash Version 2.01 ("ACT"), which constitutes the
"BankTIES ACH" software (the "Software"): and

WHEREAS, the Company desires to license the Software from the Bank for the
purpose of providing automated clearinghouse services (the "Services") through
the Bank; and

WHEREAS, the Bank and the Company have entered into an ACH Agreement for the
purposes of providing the Services (the "ACH Agreement"),

NOW, THEREFORE, the parties agree as follows:

1.   Use of Software.  The Software allows the Company to create and transmit to
     ---------------
     the Bank ACH transactions. The Bank hereby sublicenses the Software and the
     Documentation to the Company for the sole purpose of creating ACH
     transactions that will in all cases be transmitted to the Bank's host
     computer for processing and delivery to an Automated Clearing House ("ACH")
     or deposit to accounts maintained at the Bank ("on-us entries"). Each copy
     of the Software may be used on only one designated CPU and solely for the
     purpose described in this section. If, however, the Company's designated
     CPU becomes inoperative, the Company may use the Software on a temporary
     back-up CPU until the designated CPU again becomes operatonal.

2.   Tutorial System.  The Bank may choose to make available to the Company the
     ---------------
     Auto Cash Transfer Tutorial System (the "Tutorial System"). The Company
     agrees that the Tutorial System shall be used solely for use in the
     training of its employees in the use of the Software.

3.   Fee; Term.  Upon execution of this Agreement, the Company agrees to pay the
     ---------
     Bank a license as specified in the Bank's pricing schedule, receipt of
     which is hereby acknowledged by the Company. This Agreement shall commence
     on the Effective Date and shall remain in effect for the term of the ACH
     Agreement, unless canceled by either party upon prior written notice to the
     other party. Upon termination of this Agreement, the Company shall
     immediately return to the Bank all copies of the Software, the
     Documentation, and, if applicable, the Tutorial System.


                                                                         Page 3
<PAGE>

4.   Documentation.  The Bank will provide the Company with one copy of the
     -------------
     Software User Manual (the "Documentation"). Portions of the Documentation
     include documentation it has received from P&H. Those portions of the
     Documentation which have been received from P&H remain the property of P&H
     and are or may be copyrighted by P&H. All other portions of the
     Documentation remain the property of the Bank and are or may be copyrighted
     by the Bank.

5.   LIMITATION OF LIABILITY.  IN NO EVENT SHALL THE BANK BE LIABLE FOR ANY
     -----------------------
     INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES, INCLUDING BUT NOT
     LIMITED TO LOST DATA, PROGRAMS, PROFITS (ANTICIPATED, ACTUAL, OR
     OTHERWISE), OR BENEFITS RESULTING FROM USE OF, RELIANCE UPON, OR INABILITY
     TO USE THE SOFTWARE OR THE TUTORIAL SYSTEM, REGARDLESS OF WHETHER OR NOT
     THE BANK HAS BEEN INFORMED OF THE POSSIBILITY OF SUCH DAMAGES AND
     REGARDLESS OF WHETHER SUCH DAMAGES ARE BASED ON CONTRACT, TORT (INCLUDING
     NEGLIGENCE), STRICT LIABILITY, OR ANY OTHER THEORY OR FORM OF ACTION. IN NO
     EVENT SHALL THE BANK'S CUMULATIVE LIABILITY TO THE COMPANY IN RELATION TO
     THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY EXCEED A SUM EQUAL
     TO THE TOTAL LICENSE FEE ACTUALLY PAID TO THE BANK UNDER THIS AGREEMENT.

6.   WARRANTIES.  BOTH PARTIES ACKNOWLEDGE THAT THE BANK MAKES NO WARRANTIES,
     ----------
     EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE WARRANTIES OF
     MERCHANTABILITY AND OF FITNESS FOR A PARTICULAR PURPOSE. ADDITIONALLY, P&H
