                      MASTER CONSULTING SERVICES AGREEMENT

This Master Consulting Services Agreement (this "Agreement" which term shall
also include all Work Orders) is made this 14th day of September, 1999 between
INTEGRATED INFORMATION SYSTEMS, INC. ("IIS") located at 1560 W. Fountainhead
Parkway, Suite 200, Tempe, Arizona 85282 and REALINK.COM, CORPORATION, a
Delaware corporation ("Client") located at 617 South Rockford Drive, Tempe,
Arizona 85281. This Agreement sets forth the terms and conditions under which
IIS will provide services and/or materials to Client.

ARTICLE I  DEFINITIONS.

The following terms shall have the following meanings in this Agreement and all
attached Work Orders:

1.   "Project" shall mean the totality of services and materials IIS provides to
     Client pursuant to a Work Order.

2.   "Scope of Work" shall mean the specific services to be rendered by IIS to
     Client in furtherance of a Project as defined in a Work Order.

3.   "Work Order(s)" shall mean the document(s) that: (i) is numbered for
     identification; (ii) details the Scope of Work to be performed by IIS
     including all applicable deliverables or other materials to be provided;
     and (iii) specifies the applicable hourly rate or fixed price for
     performing the Scope of Work. A new Work Order will be required for each
     new Project. Each Work Order shall be effective, incorporated into, and
     form a part of this Agreement when executed by IIS and Client.

ARTICLE II  STAFFING.

1.   IIS agrees to furnish consultants qualified to render services in
     accordance with the Scope of Work set forth in a Work Order. IIS will use
     reasonable efforts to ensure the continuity of its consultants assigned to
     a Project but shall have discretion to replace or change members of its
     staff working on a Project provided that replacement personnel do not
     result in added cost to Client or delay in a Project.

ARTICLE III  FEES.

1.   IIS will bill Client at the rate(s) or in the amount specified in the
     applicable Work Order for services and materials rendered by IIS.

2.   Client shall be invoiced for expenses incurred by IIS in rendering services
     to Client including travel, meals, hotels, car rentals, special insurance
     required by Client, mileage, and other applicable expenses. Any individual
     expense in excess of $300.00 shall require the prior approval of Client.
     IIS's fees do not include any taxes, duties, tariffs or other governmental
     charges or expenses imposed in connection with this Agreement and such
     taxes shall be billed to Client.

3.   IIS's standard hours of operation are Monday through Friday (excluding all
     holidays) 8:30 a.m. to 5:30 p.m. For Work Orders performed on an hourly
     basis, services rendered by IIS on holidays or during non-standard hours of
     operation shall be billed at one and one-half the rates set forth in the
     applicable Work Order. Work during non-standard hours is subject to the
     prior approval of Client.

ARTICLE IV BILLING AND PAYMENT FOR SERVICES.

1.   IIS shall send a written invoice to Client for services rendered and
     materials provided every two weeks. Invoices are due upon receipt. Invoices
     not paid in full within thirty (30) days of the invoice date shall accrue
     interest at the rate of one and one-half percent (1.5%) per month until
     paid in full except as to those invoices (or portions of invoices) under
     dispute as set forth in subparagraph 2 below. Any amount outstanding for
     more than forty-five (45) days after the date of invoice shall constitute a
     material breach of this Agreement by Client.

2.   If Client has objection to a charge set forth in an invoice, Client shall
     send written notice of its objection to IIS, and the reasons therefor,
     within twenty (20) days of the date of the invoice being objected to. Upon
     receipt of an objection, IIS shall undertake to provide Client with back-up
     documentation to support its charge for the services and/or materials in
     dispute. If Client does not object to an invoice in writing within twenty
     (20) days of the invoice date, Client shall have accepted the charges set
     forth therein. Any disputed amounts shall not affect payment of
     non-disputed charges and expenses.

ARTICLE V  TERMINATION.

1.   Client shall have the right to terminate this Agreement and/or any Work
     Order upon fifteen (15) days' prior written notice to IIS. Client agrees to
     pay IIS for services performed up to the effective date of termination.
     Notice of termination of any Work Order shall not be considered notice of
     termination of this Agreement unless specifically stated in the notice.

2.   IIS shall have the right to terminate this Agreement and/or any Work Order
     upon fifteen (15) days' prior written notice to Client provided that IIS
     shall provide all services and materials to Client that Client has paid for
     prior to IIS's notice of termination.

3.   IIS shall have the right to terminate this Agreement and/or suspend its
     services upon three (3) days' prior written notice to Client if any IIS
     invoices remain unpaid thirty (30) days after the invoice date.

4.   Either party shall have the right to terminate this Agreement upon a
     material breach by the other party.

ARTICLE VI  NON-SOLICITATION.

1.   IIS has invested significant resources in the hiring, education,
     development, and training of its employees. Accordingly, Client agrees that
     during the term of this Agreement, and for a period of twelve (12) months
     following the termination of this Agreement, Client will not directly or
     indirectly: (i) hire or employ any of IIS's employees, consultants, or
     staff; (ii) hire or employ any former employee of IIS unless such former
     employee has not been employed by IIS for at least six (6) months; (iii)
     make an offer to or solicit any of IIS's employees to terminate their
     employment with IIS; (iv) solicit or receive any services from any of IIS's
     employees excluding the services such employees are rendering to Client in
     connection with this Agreement; or (v) use, solicit, or receive the
     services of any former IIS employee if such employee leaves the employment
     of IIS and thereafter becomes employed by any third party that is rendering
     services to Client.

2.   The parties agree that a breach of this provision will result in damages to
     IIS that are difficult to ascertain with certainty. Accordingly, in the
     event of a breach of this provision, IIS shall have the right to:

     (a)  Apply for a temporary restraining order, temporary injunction,
          permanent injunction, or other provisional remedy (collectively
          "Provisional Remedy") in any court or forum of its choosing. If IIS
          does choose to commence an action in court, the parties waive their
          right to a trial by jury;

     (b)  Receive fixed monetary damages for violation of this non-solicitation
          provision in the amount of three (3) times the annual salary IIS was
          paying to such employee(s) before a violation of this provision was
          discovered by IIS;

     (c)  Collect all costs and damages associated with a violation of this
          provision within two (2) weeks of a court's or arbitrator's
          finding/order that Client violated this non-solicitation provision
          (the "Finding"). The damages will be due even if there exists in such
          suit (or other action) issues that were not resolved by the Finding.
          Such damages shall be provable by affidavit of an IIS officer or
          employee with pertinent knowledge. A Finding can be made following:
          (i) any evidentiary hearing; (ii) any motion to dismiss; (iii) any
          hearing in connection with IIS's application for a Provisional Remedy;
          (iv) any motion for summary judgment; (v) a trial, arbitration, or
          other similar dispositive hearing; or (vi) at any other time after
          suit is initiated by IIS.

ARTICLE VII  CONFIDENTIALITY.

1.   The parties agree to retain in confidence all information transmitted to it
     by the other party pursuant to this Agreement that the disclosing party
     identifies as being proprietary and/or confidential or that, by the nature
     of the circumstances surrounding the disclosure, ought in good faith to be
     treated as proprietary and/or confidential ("Confidential Information").
     Confidential Information includes, but is not limited to: business plans
     and designs; customer, vendor, and partner lists; this Agreement and all
     Work Orders (including IIS rates); technical, financial and business
     information and models; proposed business deals, reports, plans, and market
     projections; and software programs, data, source code, and other technical
     information. The parties will not make use of such Confidential Information
     except under the terms and during the existence of this Agreement. Neither
     party will disclose to any third person any Confidential Information
     without the express consent of the other party.

                                       2

2.   Confidential Information does not include information that is: (a) already
     in the possession of the receiving party or is known by the receiving party
     at the time of receiving the same without breach of any duty owed to the
     disclosing party; (b) publicly known through no wrongful act of the
     receiving party; (c) rightfully received from a third party, provided the
     receiving party complies with any restrictions imposed by any such third
     party; or (d) disclosed by the receiving party pursuant to a requirement of
     a court order, governmental agency or other applicable law or regulation or
     disclosed in connection with any dispute resolution under this Agreement.

ARTICLE VIII LIMITATIONS.

1.   IIS makes no warranties with respect to products provided or services
     rendered pursuant to this Agreement and disclaims all warranties, express
     or implied, including, without limitation, warranties of merchantability,
     fitness for a particular purpose, title, and non-infringement.

2.   IIS shall not be liable for any incidental, special, punitive, indirect, or
     consequential damages, lost or inaccurate data, business interruption, or
     lost profits under any contract, tort (including negligence), strict
     liability, breach of warranty, or other legal or equitable theory, even if
     the remedies provided for in this Agreement fail of their essential purpose
     and even if IIS has been advised of the possibility or probability of such
     damages. IIS's liability to Client shall not exceed the amount actually
     paid by Client to IIS pursuant to the applicable Work Order giving rise to
     the dispute.

ARTICLE X INDEMNIFICATION.

1.   IIS agrees to defend Client against, and pay the amount of any adverse
     final judgment (or settlement to which IIS consents) resulting from third
     party claim(s) that the computer code or materials (other than a
     commercial/off-the-shelf product or pre-existing work of Client) developed
     by IIS and provided to Client pursuant to the terms of this Agreement
     ("Developments") infringe any United States copyright; provided that IIS is
     notified promptly in writing of the claim, has the opportunity to assume
     sole control over its defense or settlement, and Client provides reasonable
     assistance in the defense of the same.

2.   In the event IIS or Client receives information concerning a copyright
     infringement claim related to the Developments, IIS may, at its expense,
     either: (i) procure for Client the right to continue to use the alleged
     infringing Developments; or (ii) replace or modify the Developments to make
     them non-infringing, in which case Client shall thereupon cease use or
     distribution of the alleged infringing Developments.

3.   IIS shall have no liability for any infringement claim based on Client's:
     (i) specifications, directions, or requirements provided to IIS for such
     Developments; (ii) manufacture, marketing, distribution, or use of any
     Developments after written notice that Client should cease such activity
     due to such a claim; (iii) combination of any Developments with a software
     or hardware product, program, or data not supplied by IIS; or (iv)
     adaptation, enhancement, or modification of any Developments not performed
     by IIS.

4.   Client agrees to defend IIS against, and pay the amount of any adverse
     final judgment (or settlement to which Client consents) in connection with
     any claims arising under Section 3 above, or claims arising out of the
     distribution, marketing, or use of the Developments; provided that Client
     is notified promptly in writing of any such claim, and has the opportunity
     to assume sole control over its defense or settlement, and IIS provides
     reasonable assistance in the defense of the same.

5.   Client shall indemnify and hold IIS harmless from and against any and all
     claims or causes of action against IIS to the extent such claim or action
     is based on a claim that an IIS employee or consultant performing services
     at the offices or premises of Client was subject to any physical injury,
     mental injury, discriminatory conduct, harassment, or any other actionable
     activity by Client, an employee or consultant of Client, or any third party
     on Client's premises. Client shall pay the costs and damages, including
     attorneys' fees, in respect of such claim provided the Client is given
     notice in writing of such claim. Client shall control the defense of such
     action.

ARTICLE XI OWNERSHIP AND LICENSE.

A.   General Provisions.

     1.   Any commercial off-the-shelf product of IIS or a third party
          ("Commercial Product") which is provided pursuant to this Agreement
          shall be licensed to Client according to the terms of the end user
          license agreement accompanying such product.

     2.   All rights in any Code, Documentation, Deliverables, software,
          modules, or other specifications developed by or for IIS or Client
          independently of this Agreement that are provided pursuant to this
          Agreement (hereinafter "Pre-Existing Work") shall remain the sole
          property of the party providing the Pre-Existing Work. IIS hereby
          grants Client a non-exclusive, perpetual, fully paid-up license to
          use, reproduce and modify the Source Code of the IIS Pre-Existing Work
          solely for Client's internal use in connection with the Custom
          Application. Client hereby grants IIS a non-exclusive license to use,
          reproduce and modify any Pre-Existing Work of Client in connection
          with the Project.

     3.   All rights in any Code, Documentation, or the Custom Application
          (other than a Commercial Product or Pre-Existing Work) developed by
          IIS and provided to Client in the course of performance of this
          Agreement (collectively "Developments") shall be owned by Client and
          IIS. Client's ownership rights, however, shall not vest until Client
          makes all payments to IIS as required by this Agreement. Each party
          shall be free to use, enhance, and modify the Developments without any
          obligation of accounting or payment of royalties. Client shall use
          Developments for its internal purposes only and shall not sell,
          market, distribute, or license the Developments to any third party.
          Each party shall be the sole owner of any modifications that it makes
          based upon Developments.

     4.   After all IIS Deliverable Invoices and Project Invoices have been paid
          and the Warranty period has expired, IIS shall provide Client with the
          Source Code for the Custom Application which Client may modify or
          enhance for its internal purposes.

     5.   IIS may sublicense the rights granted hereunder. All rights not
          expressly granted are reserved to the parties.


ARTICLE XII MISCELLANEOUS PROVISIONS.

1.   Entire Agreement. This Agreement is a complete and exclusive statement of
     all the terms and conditions of the agreement among the parties with
     respect to the subject matter hereof. This Agreement supersedes and
     terminates any previously existing negotiations, understandings, and
     agreements that may exist between the parties. This Agreement shall not be
     varied, supplemented, qualified or interpreted by any prior course of
     dealing between the parties hereto or by any usage of trade.

2.   Headings. Headings and captions in this Agreement are for convenience only
     and are not to be used to interpret this Agreement.

3.   Severability. If any provision of this Agreement is found to be illegal or
     unenforceable, then, notwithstanding such finding, this Agreement shall
     remain in full force and effect and such provision shall be deemed stricken
     or modified to the minimum extent necessary to make it enforceable;
     provided, however, that the intent of the parties when entering into this
     Agreement is maintained.

4.   Assignment. This Agreement and any rights or obligations hereunder shall
     not be assigned by contract or operation of law without the prior written
     agreement of both parties except in such case where all or substantially
     all of the assets or stock of a party to this Agreement is sold to a third
     party and such third party agrees in writing to be bound by the terms and
     conditions of this Agreement. Upon prior consent of Client, IIS may use
     subcontractors to perform services for Client in connection with a Project.

5.   Amendment and Waiver. Except as otherwise expressly provided herein, this
     Agreement may only be amended or modified in a writing signed by both
     parties. The failure of either party to enforce its rights under this
     Agreement at any time for any period shall not be construed as a waiver of
     such rights and shall not be deemed a waiver of any right of either party
     to insist upon the strict performance of this Agreement.

6.   Independent Contractor. IIS shall act as an independent contractor and
     shall be responsible for all social security, unemployment, workers'
     compensation, and other withholding taxes for all of its employees.

7.   Force Majeure. Except for Client's obligation to pay for services/materials
     rendered by IIS, if either party is prevented from complying, either
     totally or in part, with any of the terms or provisions of this Agreement
     by reason of fire, flood, storm, strike, lockout, or other labor trouble,
     riot, war, rebellion, accident or other acts of God, then upon written
     notice to the other party, the requirements of this Agreement, or the
     affected provisions hereof to the extent affected, shall be suspended
     during the period of such disability. During such period, the party not
     prevented from complying may seek to have its needs (which would otherwise
     be met hereunder) met by others without liability hereunder. The party
     prevented from complying shall make all reasonable efforts to remove such
     disability within thirty (30) days of giving such notice.

8.   Compliance with Laws. IIS and Client shall comply with all applicable laws
     and regulations with respect to this Agreement. Client acknowledges that
     the services provided by IIS and the related software and other materials
     are subject to United States export control laws and regulations and Client
     confirms that it will not export or re-export them, directly or indirectly,
     either to: (i) any countries that are subject to U.S. export restrictions

     Libya, North Korea, Syria, and Sudan), or to any national of any such
     country; or (ii) any end-user whom Client knows or has reason to know will
     utilize them in the design, development, or production of nuclear,
     chemical, or biological weapons; or (iii) any end-user who has been
     prohibited from participating in U.S. export transactions by any federal
     agency of the U.S. government.

9.   Governing Law. This Agreement shall be construed pursuant to the laws of
     the State of Arizona. Unless waived by IIS, the exclusive jurisdiction and
     venue of any action related to this Agreement, including the enforcement of
     any arbitration award, shall be the Maricopa County Superior Court, Arizona
     and the parties submit to the jurisdiction and venue of such court for the
     purpose of any such action.

10.  Arbitration. Any dispute, claimed breach, or controversy arising out of or
     in relation to this Agreement shall be settled by binding arbitration in
     Phoenix, Arizona in accordance with the then-prevailing Commercial
     Arbitration Rules of the American Arbitration Association by a single
     arbitrator mutually agreed upon by both parties, and applying Arizona state
     law without regard to the conflicts of law provisions thereof, or if
     applicable, U.S. federal law. The arbitration award shall be final and
     binding upon the parties. Notwithstanding the foregoing, either party shall
     have the right to seek and obtain appropriate equitable and Provisional
     Remedies exclusively in Maricopa County Superior Court, Arizona.

11.  Remedies. The rights and remedies of a party set forth herein with respect
     to the failure of the other to comply with the terms of this Agreement
     (including, without limitation, rights of termination of this Agreement)

     remedies, and the aggrieved party shall in all events be entitled to seek
     whatever additional remedies may be available in law or in equity.

12.  Attorneys' Fees. The prevailing party in any action that arises out of this
     Agreement shall be entitled to recover costs and expenses including,
