                            SECTION 5. - WARRANTIES

        5.1 AS-DOCUMENTED WARRANTY. MobiNetix warrants to FSG that until
Software Acceptance is achieved under the License Agreement, each Unit
purchased will perform in accordance with the Specifications therefor,
including any engineering changes that may be implemented by MobiNetix from
time to time during such period in respect of the applicable model of Units
(this warranty being referred to herein as the "AS-DOCUMENTED WARRANTY"). FSG's
sole remedy upon the failure of any Unit to comply with the as-documented
warranty will be to obtain, repair or a replacement of such Unit or the
Software component thereof. Notwithstanding the foregoing, it shall be a
MobiNetix event of default under SECTION 10.3(ii), if any single shipment of
Units fails to achieve Acceptance as a result of the failure of this warranty.

        5.2 PHYSICAL WARRANTY. For purposes of this SECTION 5.2, the warranty
period as to each Unit shall continue for thirty-six (36) months commencing (i)
as to all Units in a shipment of Units that achieved Shipment Acceptance, at
the time such shipment is received at the designated FSG location, and (ii) as
to all Units in a shipment of Units that fails to achieve Shipment Acceptance,
at such time as the replacement shipment achieves Shipment Acceptance (if FSG
does not exercise its right to terminate this Agreement pursuant to SECTION
10.2). MobiNetix warrants to FSG that, during the warranty period, each Unit
provided by


                                                                          Page 7
<PAGE>   8
MobiNetix will be free from defects in materials and workmanship. MobiNetix's
obligation in respect of this warranty during the initial ninety (90) days of
the applicable warranty period, is to replace or repair all Units that fail to
achieve Unit Acceptance, whether or not contained within a shipment of Units
that has failed to achieve Shipment Acceptance, and all such Units that
subsequently fail to perform. Except as stated in the immediately preceding
sentence, MobiNetix's obligation in respect of this warranty after the
expiration of such ninety (90) day period as to each Unit shall be to provide
all the requisite parts only during the warranty period, the parties having
agreed that the purchase price per Unit payable by FSG relieves MobiNetix of
its obligation to provide the requisite labor during the remaining thirty-three
(33) months of the warranty period. Upon the failure of any Unit to comply with
this warranty, FSG's sole remedy will be to obtain the repair or replacement of
such Unit, provided that any replacement made of individual Units contained
within a shipment of Units that has achieved Shipment Acceptance shall not
extend the warranty period specified above. Notwithstanding the foregoing, it
shall be a MobiNetix event of default under SECTION 10.3(ii), if any single
shipment of Units fails to achieve Shipment Acceptance as a result of the
failure of this warranty. The warranty contained in this SECTION 5.2 shall not
apply to defects resulting from abuse by non-MobiNetix personnel, vandalism,
acts of God or other perils.

        5.3 PARTS INVENTORY WARRANTY. As early as practicable after the date
hereof, MobiNetix shall deliver to FSG's facility known as the Tampa National
Rework Center, (i) an inventory of warranty parts that is deemed adequate for
the purpose of ensuring the fulfillment of MobiNetix's warranty obligations
under SECTION 5 in respect of the Initial Units, and (ii) all documentation and
schematics available, including test routines. [*] MobiNetix shall replenish
parts withdrawn from inventory within fifteen (15) days after receipt of FSG's
notice and ensure the continuous maintenance of an inventory of parts as
required by this Section for so long as MobiNetix has any obligations pursuant
to SECTION 5.2. From time to time the parties shall review the actual needs of
FSG for parts and adjust the required inventory quantity as necessary.

trade name or similar proprietary right conferred by common law or by any
statute that is alleged to have occurred because of systems, services, software
or other products provided or work performed by MobiNetix, and to indemnify
FSG, as Indemnitee, against any court-awarded damages, liabilities, costs and
expenses for such infringement or misappropriation. In the event FSG is
enjoined by reason of any infringement claim, or is believed likely by FSG to
become the subject of a meritorious infringement claim, MobiNetix shall, at its
expense, either:

          (i)    procure the right to continue to use the affected system,
                 service, software or other product or any component thereof,
                 as contemplated hereunder,

          (ii)   replace or modify the affected system, service, software, or
                 other product, or any component thereof, to permit the
                 performance of such function or to render use of the affected
                 system, service, software or other product, or any component
                 thereof, non-infringing while performing substantially the same
                 functions without substantial degradation of performance, or

          (iii)  if any of the options stated in clauses (i) or (ii) above is
                 not reasonably available, refund to FSG the entire purchase
                 price paid by FSG for the affected system, software or product,
                 including the purchase price paid for any system, software or
                 product that is not directly the subject of the infringement
                 claim but is rendered unusable as a result of the


                                                                         Page 13
<PAGE>   14
                  discontinuance of the availability of the affected system,
                  product or software.

        8.3   CONDUCT OF LITIGATION. In the event a claim or judicial action is
brought or threatened against the Indemnitee with respect to matters covered by
SECTIONS 8.1 or 8.2, the Indemnitor shall pay the costs and damages awarded in
any such claim or action or the cost of settling such claim or action and the
Indemnitor shall have the right to defend such claim or action at its expense
and to control the defense and settlement, provided, that the Indemnitee shall
have the right to participate in such defense and negotiations using counsel at
its own expense and Indemnitor shall obtain Indemnitee's consent, which shall
not be unreasonably withheld, prior to entering into a settlement or compromise
or consenting to any injunctive relief with respect to such claim or action. The
obligations of the Indemnitor hereunder are subject to its receiving prompt
notice of any claims for indemnification, and the Indemnitee reasonably
cooperating in the defense thereof.

        8.4     LIMITATION OF LIABILITY. Subject to the indemnification
obligations contained in SECTIONS 8.1 and 8.2, neither party will be liable for
any claim or demand against the other, its officers, directors, partners,
principal, members, managers, employees, agents or representatives by any third
party nor for any amounts representing loss of profit, loss of business or
special indirect, incidental, consequential or punitive damages, even if such
party has been advised of the possibility of such damages, or damages that could
have been avoided, using reasonable diligence, by the other party. Subject to
the indemnification obligations of the parties contained in SECTIONS 8.1 and
8.2, each party's liability for any reason whatsoever arising under or relating
to this Agreement, regardless of the form of the cause of action, whether in
contract, statute or tort (including negligence) or otherwise, shall  in no
event exceed in the aggregate an amount equivalent to (i) in the case of
MobiNetix, the amounts actually received by MobiNetix from FSG hereunder, or
(ii) in the case of FSG, the amounts paid to MobiNetix by FSG hereunder.

        8.5     EXCUSE FOR NON-PERFORMANCE. To the extent that and only for so
long as one party (the "DEFAULTING PARTY") fails to perform an obligation which
failure prevents or renders impracticable the performance of an obligation by
the other party (the "NON-DEFAULTING PARTY") the non-defaulting party shall be
excused from such performance, provided that the non-defaulting party shall (i)
notify the defaulting party if possible and as soon as practicable 


                                                                         Page 14
<PAGE>   15
describing the default and explaining how the non-defaulting party's
performance has been affected; (ii) use reasonable efforts to mitigate the
effect of the defaulting party's failure; and (iii) perform its obligations
hereunder to the extent reasonably practicable. The defaulting party shall use
diligent, uninterrupted efforts to cure its default and eliminate the effects
thereof.

                        SECTION 9. - DISPUTE RESOLUTION

     Any dispute between the parties arising out of or relating to this
Agreement, including with respect to the interpretation of any provision of
this Agreement, conformance or non-conformance of the Units and performance by
MobiNetix or FSG hereunder, shall be resolved as provided in this SECTION 9.

     9.1  INFORMAL DISPUTE RESOLUTION. Prior to the initiation of formal
dispute resolution procedures, the parties shall first attempt to resolve their
dispute informally, as follows:

         (i)   Upon the written request of either party containing a short
               statement as to the nature of the dispute and the requesting
               party's position with respect thereto, each party shall appoint a
               designated representative who does not devote substantially all
               of his or her time to performance under this Agreement, whose
               task it will be to meet for the purpose of endeavoring to resolve
               such dispute.

         (ii)  The designated representatives shall meet as often as the parties
               reasonably deem necessary in order to gather and furnish to the
               other all information with respect to the dispute which the
               parties believe to be appropriate and germane in connection with
               the resolution of the dispute. The representatives shall discuss
               and attempt to resolve the dispute without the necessity of any
               formal proceeding.

         (iii) During the course of discussion, all reasonable requests made by
               one party to another for nonprivileged information reasonably
               related to this Agreement shall be honored in order that each of
               the parties may be fully advised of the other's position.


                                                                         Page 16
<PAGE>   16
     (iv) Formal proceedings for the resolution of the dispute pursuant to
          Section 9.2 or 9.3 shall not be commenced until the earlier of:

          (a)  either of the designated representatives concludes in good faith
               that amicable resolution through continued negotiation of the
               dispute does not appear likely and so stating in a notice to the
               other designated representative or in a joint declaration signed
               by each of them; or

          (b)  thirty (30) days after the initial written request to appoint a
               designated representative pursuant to SECTION 9.1(i)(this period
               shall be deemed to run notwithstanding any claim that the process
               described in this SECTION 9.1 was not followed or completed).

This SECTION 9.1 shall not be construed to prevent a party from instituting,
and a party is authorized to institute, formal proceedings earlier to avoid the
expiration of any applicable limitations period, or to preserve a superior
position with respect to other creditors, or as provided in SECTIONS 9.3.

     9.2  ARBITRATION. If the parties are unable to resolve a dispute as
provided in SECTION 9.1, then such dispute may be submitted to mandatory and
binding arbitration pursuant to the following conditions:

          (i)  Agreement to Arbitrate. Provided the parties specifically agree
               in writing signed by authorized representatives specifically
               referencing this SECTION 9.2 to submit to arbitration, any
               dispute, claim, or controversy relating in any way to this
               Agreement may be settled by arbitration in San Francisco,
               California, in accordance with the Commercial Arbitration Rules
               of the American Arbitration Association (the "AAA").

          (ii) Award, Expenses. The award of the arbitrator shall be final and
               binding on the parties, and judgment thereon may be entered in
               any court of competent jurisdiction. Each party to the
               arbitration shall pay an equal part of the deposit fixed by the
               AAA. Notwithstanding the determination of the arbitrator (i) all
               costs associated with the arbitration and imposed by the AAA or
               the arbitrator shall be borne equally by each party to the
               arbitration, and (ii) each party to the arbitration shall be
               responsible for its

                                                                         Page 16

               own attorneys' fees and other professional fees incurred in
               connection with the arbitration.

     9.3  LITIGATION.

               (i)      Immediate Injunctive Relief. If a party makes a good
                        faith determination that a breach of the terms of this
                        Agreement by the other party is such that a temporary
                        restraining order or other injunctive relief is the only
                        appropriate and adequate remedy, such party shall be
                        authorized to seek immediate injunctive relief without
                        regard to SECTION 9.1 OR 9.2.

               (ii)     Litigation in Lieu of Arbitration. So long as no
                        arbitration proceeding has been commenced by one party
                        and accepted by the other party as provided in SECTION
                        9.2(i), after the dispute resolution procedure set forth
                        in SECTION 9.1 has been complied with, either party
                        shall be authorized to initiate litigation in order to
                        resolve the dispute.

               (iii)    Jurisdiction. The Parties consent to venue in Atlanta,
                        Georgia or in San Francisco, California and to the
                        exclusive jurisdiction of competent state or federal
                        courts in California for all litigation which may be
                        brought, subject to any requirement for informal dispute
                        resolution hereunder or prior agreement of the parties
                        to arbitrate, with respect to the terms of, and the
                        transactions and relationships contemplated by, this
                        Agreement.

     9.4  CONTINUED PERFORMANCE. Each party agrees to continue performing its
obligations under this Agreement while any dispute is being resolved except to
the extent the issue in dispute precludes performance provided that any dispute
over payment shall not be deemed to preclude performance.

     9.5  WAIVER OF JURY TRIAL.

     EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE
UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND
THEREFORE EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT
MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY
ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE PERFORMANCE OF THE SERVICES.

VOLUNTARILY, AND (iii) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT
BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION

SECTION 10.4.

        10.3    EVENT OF DEFAULT. It shall be an event of default if any of the
following shall occur and be continuing:

                (i)     FSG shall fail to pay any sum required to be paid
                        hereunder and not disputed and such failure continues
                        for thirty (30) days following receipt by FSG of
                        MobilNetix's notice of non-payment;

                (ii)    Either party shall fail to perform any covenant or
                        obligation hereunder or under the License Agreement, or
                        any representation or warranty of either party shall
                        fail, and any such failure continues for thirty (30)
                        days following receipt by such defaulting party of a
                        notice of default from the other, provided, that, prior
                        to an event of default hereunder being deemed to arise
                        for purposes of SECTION 6.4, and only for purposes of
                        SECTION 6.4, if such failure cannot reasonably be cured
                        within thirty (30) days and the defaulting party has
                        commenced and is diligently proceeding to cure the
                        default, the defaulting party shall have an additional
                        period, as reasonably necessary and by agreement of the
                        parties, to cure the default;

                                                                         Page 18
<PAGE>   19
          (iii)  Any party shall not pay its debts as they become due or shall
                 make a general assignment for the benefit of its creditors, or
                 any proceeding shall be instituted by or against such party
                 seeking to adjudicate it a bankrupt or insolvent, or seeking
                 liquidation, reorganization, adjustment or other relief under
                 any law relating to bankruptcy or reorganization, or seeking an
                 order for relief or the appointment of a receiver, trustee or
                 other similar official for a substantial part of its property
                 and such proceeding has not been stayed or dismissed within
                 sixty (60) days; or 

          (iv)   Any of the conditions that could result in a release of the
                 Escrow Materials pursuant to SECTION 6 occur.

     10.4 FORCE MAJEURE.

          (i)    No party shall be liable for any default or delay in the
                 performance of its obligations under this Agreement if and to
                 the extent such default or delay is caused, directly or
                 indirectly by: (a) fire, flood, earthquake, elements of nature
                 or acts of God; (b) riots, civil disorders, rebellions or
                 revolutions in any country; or (c) any other cause beyond the
                 reasonable control of such party, including electronic
                 failures, provided the non-performing party is without fault in
                 causing such default or delay, and such default or delay could
                 not have been prevented by reasonable precautions and cannot
                 reasonably be circumvented by the non-performing party through
                 the use of alternate sources, workaround plans or other means.
                 Notwithstanding the foregoing, the failure of MobiNetix's
                 warranty relating to Year 2000 compliance as contained in
                 SECTION 5.3 shall not be excused as a "force majeure" event.

          (ii)   In such event the non-performing party shall be excused from
                 further performance or observance of the obligation(s) so
                 affected for as long as such circumstances prevail and such
                 party continues to use its commercially reasonable efforts to
                 recommence performance or observance whenever and to whatever
                 extent possible without delay. Any party so delayed in its
                 performance shall immediately notify the party to whom
                 performance is due by telephone (to be confirmed in writing
                 within

                                                                         Page 19
<PAGE>   20
                 two (2) days of the inception of such delay) and describe at a
                 reasonable level of detail the circumstances causing such
                 delay.

          (iii)  If any force majeure event substantially prevents, hinders
                 or delays performance hereunder for more than sixty (60) days,
                 then FSG may terminate this Agreement. MobiNetix shall not have
                 the right to any additional payments from FSG for costs or
                 expenses incurred by MobiNetix as a result of any force majeure
                 occurrence.

all of the assets of FSG. MobiNetix may not assign this Agreement, or any of its
other interests herein without the prior written consent of FSG except as

reason of an assignment for the benefit of creditors, or (ii) a change in the
ownership structure or control of MobiNetix, including the merger or
consolidation of MobiNetix with or into another entity, then FSG shall have the

unconditional right and option to terminate this Agreement, provided, that FSG
may not withhold its consent to terminate this Agreement if any of the events
described in subclauses (i) or (ii) above do not, in FSG's reasonable sole
judgment, result in either (x) an adverse change in the financial condition of

purposes hereof will be deemed to be the resignation, removal or absence of the
persons currently holding the positions of CEO, CFO, Senior Program Manager

and such other senior personnel who currently are equity owners of MobiNetix
and actively engaged in its business operations as employees), or (z) the

FSG's parent, Federated Department Stores, Inc. MobiNetix shall inform FSG of
any and all such assignments or changes in control or structure, including any
other substantive changes in the structure of its business within thirty (30)
days after the occurrence of such event.

     11.4  RELATIONSHIP OF PARTIES.  In performing under this Agreement, the
parties are acting as independent contractors and this Agreement shall not be
construed as imposing liability upon one party for the acts or omissions of the
other or as providing either party with the right, power or authority to impose
any duty or obligation on the other except as expressly provided herein.

     11.5  COMPLIANCE WITH LAWS.  Each party agrees that it shall obtain all
licenses and other governmental authorizations and approvals required for the

                           PREFERRED ESCROW AGREEMENT

                         Account Number_________________


This Agreement is effective March 17, 1998 among Data Securities International,
Inc. ("DSI"), MobiNetix Systems Inc. ("Depositor") and Federated Systems Group
Inc. ("Preferred Beneficiary"), who collectively may be referred to in this
Agreement as "the parties."

A.      Depositor and Preferred Beneficiary have entered or will enter into a
license agreement, development agreement, and/or other agreement regarding
certain proprietary technology of Depositor (referred to in this Agreement as
"the license agreement").

B.      Depositor desires to avoid disclosure of its proprietary technology
except under certain limited circumstances.

C.      The availability of the proprietary technology of Depositor is critical
to Preferred Beneficiary in the conduct of its business and, therefore,
Preferred Beneficiary needs access to the proprietary technology under certain
limited circumstances.

D.      Depositor and Preferred Beneficiary desire to establish an escrow with
DSI to provide for the retention, administration and controlled access of the
proprietary technology materials of Depositor.

E.      The parties desire this Agreement to be supplementary to the license
agreement pursuant to 11 United States [Bankruptcy] Code, Section 365(n).


ARTICLE 1 -- DEPOSITS

1.1     Obligation to Make Deposit. Upon the signing of this Agreement by the
parties, Depositor shall deliver to DSI the proprietary information and other
materials ("deposit materials") required to be deposited by the license
agreement or, if the license agreement does not identify the materials to be
deposited with DSI, then such materials will be identified on an Exhibit A. If
Exhibit A is applicable, it is to be prepared and signed by Depositor and
Preferred Beneficiary. DSI shall have no obligation with respect to the
preparation, signing or delivery of Exhibit A.

1.2     Identification of Tangible Media. Prior to the delivery of the deposit
materials to DSI, Depositor shall conspicuously label for identification each
document, magnetic tape, disk, or other tangible media upon which the deposit
materials are written or stored, Additionally, Depositor shall complete Exhibit
B to this Agreement by listing each such tangible media by the item label
description, the type of media and the quantity. The Exhibit B must be signed by
Depositor and delivered to DSI with the deposit materials. Unless and until
Depositor makes the initial deposit with DSI, DSI shall have no obligation with
respect to this Agreement, except the obligation to notify the parties regarding
the status of the deposit account as required in Section 2.2 below.


<PAGE>   32
1.3     Deposit Inspection. When DSI receives the deposit materials and the
Exhibit B, DSI will conduct a deposit inspection by visually matching the
labeling of the tangible media containing the deposit materials to the item
descriptions and quantity listed on the Exhibit B. In addition to the deposit
inspection, Preferred Beneficiary may elect to cause a verification of the
deposit materials in accordance with Section 1.6 below.

1.4     Acceptance of Deposit. At completion of the deposit inspection, if DSI
determines that the labeling of the tangible media matches the item descriptions
and quantity on Exhibit B, DSI will date and sign the Exhibit B and mail a copy
thereof to Depositor and Preferred Beneficiary. If DSI determines that the
labeling does not match the item descriptions or quantity on the Exhibit B, DSI
will (a) note the discrepancies in writing on the Exhibit B; (b) date and sign
the Exhibit B with the exceptions noted; and (c) provide a copy of the Exhibit B
to Depositor and Preferred Beneficiary. DSI's acceptance of the deposit occurs
upon the signing of the Exhibit B by DSI. Delivery of the signed Exhibit B to
Preferred Beneficiary is Preferred Beneficiary's notice that the deposit
materials have been received and accepted by DSI.

1.5     Depositor's Representations. Depositor represents as follows:

        a.      Depositor lawfully possesses all of the deposit materials
                deposited with DSI;

        b.      With respect to all of the deposit materials, Depositor has the
                right and authority to grant to DSI and Preferred Beneficiary
                the rights as provided in this Agreement;

        c.      The deposit materials are not subject to any lien or other
                encumbrance;

        d.      The deposit materials consist of the proprietary information and
                other materials identified either in the license agreement or
                Exhibit A, as the case may be; and


        e.      The deposit materials are readable and useable in their current
                form or, if the deposit materials are encrypted, the decryption
                tools and decryption keys have also been deposited.

1.6     Verification. Preferred Beneficiary shall have the right, at Preferred
Beneficiary's expense, to cause a verification of any deposit materials. A
verification determines, in different levels of detail, the accuracy,
completeness, sufficiency and quality of the deposit materials. If a
verification is elected after the deposit materials have been delivered to DSI,
then only DSI, or at DSI's election an independent person or company selected
and supervised by DSI, may perform the verification.

1.7     Deposit Updates. Unless otherwise provided by the license agreement,
Depositor shall update the deposit materials within 60 days of each release of a
new version of the product which is subject to the license agreement. Such
updates will be added to the existing deposit. All deposit updates shall be
listed on a new Exhibit B and the new Exhibit B shall be signed by Depositor.
Each Exhibit B will be held and maintained separately within the escrow account.
An independent record will be created which will document the activity for each
Exhibit B. The processing of all deposit updates shall be in accordance with
Sections 1.2 through 1.6 above. All references in this Agreement to the deposit
materials shall include the initial deposit materials and any updates.

DSI shall not disclose the content of this Agreement to any third party. If DSI
receives a subpoena or other order of a court or other judicial tribunal
pertaining to the disclosure or release of the deposit materials, DSI will
immediately notify the parties to this Agreement. It shall be the responsibility
of Depositor and/or Preferred Beneficiary to challenge any such order; provided,
however, that DSI does not waive its rights to present its position with respect
to any such order. DSI will not be required to disobey any court or other
judicial tribunal order. (See Section 7.5 below for notices of requested 
orders.)

2.2     Status Reports. DSI will issue to Depositor and Preferred Beneficiary a
report profiling the account history at least semi-annually. DSI may provide
copies of the account history pertaining to this Agreement upon the request of
any party to this Agreement.

2.3     Audit Rights. During the term of this Agreement, Depositor and Preferred

3.1     Title to Media. Depositor hereby transfers to DSI the title to the media
upon which the proprietary information and materials are written or stored.
However, this transfer does not include the ownership of the proprietary

the hardware and/or software needed.

to transfer the deposit materials to Preferred Beneficiary upon any release of
the deposit materials for use by Preferred Beneficiary in accordance with

Agreement, DSI shall not transfer the deposit materials.

                pursuant to the license agreement; or

        b.      Depositor's failure to continue to do business in the ordinary
                course.

Preferred Beneficiary that there is a dispute to be resolved pursuant to the
Dispute Resolution section (Section 7.3) of this Agreement. Subject to Section
5.2, DSI will continue to store the deposit materials without release pending

Beneficiary. However, DSI is entitled to receive any fees due DSI before making
the release. This Agreement will terminate upon the release of the deposit
materials held by DS1.

4.5     Right to Use Following Release. Unless otherwise provided in the license
agreement, upon release of the deposit materials in accordance with this Article
4, Preferred Beneficiary shall have the right to use the deposit materials for

confidentiality of the released deposit materials.

        d.      The obligation to pay DSI any fees and expenses due;

        e.      The provisions of Article 7; and

applicable to the services provided. DSI shall notify the party responsible for

written notice, request, or instruction has the authority to do so. DSI shall
not be responsible for failure to act as a result of causes beyond the
reasonable control of DSI.

                         SYSTEMS ACQUISITION AGREEMENT
                                        

        AMENDMENT, dated as of March 20, 1998 (this "Amendment"), to the
Systems Acquisition Agreement, dated as of March 16, 1998 (the "Agreement"), by
and between MobiNetix Systems, Inc. ("MobiNetix") and Federated Systems Group,

                        3.3     PURCHASE PRICE ADVANCE. Notwithstanding anything
                to the contrary herein contained, (i) FSG has paid to MobiNetix
                $5,000,160 as the purchase price for the first 11,364 Initial
                Units to be purchased by FSG hereunder; (ii) the provisions of
                Section 3.2 (other than the second sentence of such Section)
                shall not apply to the first [*] Initial Units so purchased;
                and (iii) without intending to limit the generality or effect of
                the second sentence of Section 3.2, with respect to any Unit
                delivered by MobiNetix in respect of its obligations with
                respect to the first [*] Initial Units to be purchased by FSG
                hereunder that subsequently fails to achieve Unit Acceptance,
                FSG may offset amounts paid to MobiNetix as the purchase price
                for such Initial Units as set forth in clause (i) above against
                any other payment required to be made by FSG hereunder. In the
                event that [*] Initial Units shall not have achieved Unit
                Acceptance prior to the termination of this Agreement, (i) as
                promptly as practicable following such termination, MobiNetix
                will pay FSG an amount equal to (a) $5,000,160 less (b) the
                product of (1) [*] and (2) the number of Initial Units that
                either (A) have achieved Unit Acceptance or (B) are included in
                a shipment that has achieved Shipment Acceptance and (ii)
                thereafter MobiNetix shall promptly reimburse FSG [*] for each
                Initial Unit that subsequently fails to achieve Unit Acceptance.
                The provisions of the immediately preceding sentence of this
                Section 3.3 shall survive the termination of this Agreement.

        Section 2. CONTINUED EFFECTIVENESS. Except as specifically amended
