         The amount of each Annual Contingent Payment shall be an amount equal
         to seventy-five percent (75%) of the product of: (i) a fraction, the
         numerator of which shall be the actual amount of Net Operating Profit
         and the denominator of which shall be the Target Net Operating Profit
         for that same fiscal year set forth in the table above, multiplied by
         (ii) the amount of the Payout for the Applicable Fiscal Year as set
         forth in the table above as well as any Holdback from the prior year.
         If the Net Operating Profit is greater than the Target Net Operating
         Profit for any Applicable Fiscal Year, the Annual Contingent Payment
         shall not exceed the payout for each Applicable Fiscal Year @ 100% of
         Target indicated in the table above.   Example: If the actual amount
         of the Net Operating Profit for 1999 is $400,000 and the Target Net
         Operating Profit for 1999 is $500,000, the amount of the Annual
         Contingent Payment for 1999 would be $450,000 =
         75%X($400,000/$500,000)X($750,000).  If the actual amount of the Net
         Operating Profit during 2000 is $400,000 and the Target Net Operating
         Profit for 2000 is $600,000, the amount of the Annual Contingent
         Payment for 2000 would be $525,000 =
         75%X($400,000/$600,000)X($750,000) PLUS $150,000, the Holdback from
         the previous Applicable Fiscal Year.  The entire amount of the Annual
         Contingent Payment for 2003 will be paid on or before the 90th day
         after the end of the twelve month period ended December 31, 2003.

1.5      ALLOCATION OF PURCHASE PRICE.  The allocation of the Purchase Price
         shall be agreed to by the Purchaser and the Sellers and shall be as
         set forth on a schedule to be prepared by the Sellers and agreed to by
         the parties within thirty (30) days from the date hereof.  The
         Purchaser and the Sellers agree to use such allocation in reporting
         the terms of the transactions contemplated by this Agreement to the
         United States Internal Revenue Service and any other relevant taxing
         authority and shall take all reasonable steps to minimize the taxes to
         be incurred so long as each such step is in the best interest of each
         party.

1.6      EXCLUDED LIABILITIES.  Notwithstanding the Assumed Contracts referred
         to in Article 1.2(c) above, the Purchaser shall not assume or agree to
         perform, pay or discharge, and the Sellers will remain unconditionally
         liable for, all obligations, liabilities and commitments (fixed or
         contingent) of the Sellers and the RF-ID Technology Business other
         than the Assumed Contracts including, without limitation, the
         following, whether now in existence or hereafter arising after the
         date hereof from actions taken or circumstances existing on or prior
         to the date hereof: (i) any special severance or termination payment
         to any of the Sellers' employees who are terminated by the Sellers;
         (ii) any liability or claim with respect to accidents, occurrences,
         acts or omissions arising prior to the Closing, (iii) all worker's
         compensation claims and all litigation claims, income tax or other tax
         liabilities; (iv) all liabilities incurred in connection with the
         violation or asserted violation of any occupational safety, wage,
         health, welfare, employee benefit or environmental laws or
         regulations; (v) all products liability claims and (vi) all other
         contracts and liabilities of any kind or nature of the Sellers or the
         RF-ID Technology Business.  Notwithstanding the foregoing, the
         Purchaser shall pay the Sellers' rent at its Dulles, Virginia,
         facility for three (3) months following the Closing.  The Purchaser,
         however, is not assuming any other obligation of the Sellers under the
         terms of that lease or any other to which the Sellers are a party.

         written consent of the Purchaser, except (i) any information or
         document required to be disclosed by law or (ii) information that
         becomes public knowledge through means other than an act of either the
         Sellers or the Shareholders.

2.5      NON-COMPETITION.

                 (a)      Coverage.  The Sellers and the Shareholders each
         hereby acknowledge that the Purchaser conducts Purchaser Activities
         throughout the Territory, and acknowledges that to protect adequately
         the interest of Purchaser in the practice of the RF-ID Technology
         after the date of this Agreement, it is essential that any noncompete
         covenant with respect thereto cover all Purchaser Activities and the
         entire Territory.

                 (b)      Covenant.  During the applicable Noncompete Period,
         the Sellers and the Shareholders shall not in any manner (other than
         as an employee of or a consultant to the Purchaser or any affiliate of
         Purchaser), directly or by assisting others, engage in, have an equity
         or profit interest in, or render services (of an executive, marketing,
         manufacturing, research and development, administrative, financial or
         consulting nature) to any business that conducts any of the Purchaser
         Activities in the Territory.  Notwithstanding anything herein to the
         contrary, nothing in this Agreement shall prevent or prohibit the
         Sellers or a Shareholder from owning (i) not more than 5% of a class
         of equity securities issued by any entity listed on any national
         securities exchange or interdealer quotation system or (ii) shares of
         stock of Access Control Technologies, Inc.

2.6      NONSOLICITATION OF EMPLOYEES AND CUSTOMERS.  During the
Nonsolicitation Period, the Sellers and the Shareholders shall not in any

         customers, for purposes of providing products or services that are
         competitive with the Purchaser Activities; or

                 (b)      recruit or hire away or attempt to recruit or hire
         away, on his behalf or on behalf of any other person, firm or

         products or services that are competitive with the Purchaser
         Activities.

For the purposes of this section, a person shall be considered an employee at
the time of solicitation or recruitment if they were an employee of the
Purchaser or one of its affiliates during the 45 day period prior to such
solicitation or recruitment.

2.7      ACKNOWLEDGMENT.  The Sellers, the Shareholders and the Purchaser each
acknowledge and agree that the covenants set forth in Sections 2.3, 2.4, 2.5
and 2.6 are reasonable as to time, scope and territory given the Purchaser's
need to protect its Trade Secrets, Confidential Information and its substantial
investment in its customer base, particularly given (i) the complexity and
competitive nature of the Purchaser's business and (ii) that each Shareholder
has sufficient skills to find alternative, commensurate employment or
consulting work that would not violate Sections 2.3, 2.4, 2.5 or 2.6.

2.8      FURTHER ASSURANCES.  Each party hereto from time to time hereafter at
any other party's request and without further consideration shall execute and
deliver to such other party such instruments of transfer, conveyance and
assignment in addition to those delivered pursuant to this Agreement as shall
be reasonably requested to transfer, convey and assign more effectively the
RF-ID Technology Assets  to the Purchaser, the costs of which shall be paid by
the requesting party.

2.9      RESTRICTIONS ON TRANSFERABILITY OF AXSI SHARES.  Subject to the terms
of Article 3.1.16(b), the Sellers hereby agree not to sell, transfer or
otherwise encumber any of the AXSI Shares until the first anniversary of the
Closing.  After the first anniversary of the Closing, the Sellers shall, at
their option, be permitted to sell 100,000 shares of the AXSI Shares and an
additional 100,000 shares of AXSI Shares after each of the second through
fourth anniversary dates of the Closing.  Notwithstanding the foregoing,
nothing herein shall prevent (i) the Sellers from distributing the AXSI Shares
to the Shareholders or (ii) the Shareholders from distributing the AXSI Shares
to family members to either satisfy existing obligations to such family members
or for estate planning purposes or (iii) the Sellers from distributing the AXSI
Shares to certain creditors approved in writing by the Purchaser.  Upon the
written request of the Sellers or the Shareholders following the Closing, the
Purchaser shall use its reasonable best efforts to cause its transfer agent to
collect and distribute replacement stock certificates to each transferee
according to the written instructions of Sellers or any Shareholder so long as
the transfers contemplated by such instructions are permitted under applicable
law.

2.10     AVAILABILITY OF RULE 144.  The Purchaser shall take all commercially
reasonable steps to file future reports with the Securities and Exchange
Commission on a timely basis and otherwise satisfy the prerequisites to permit
the Sellers to utilize Rule 144 with respect to the AXSI Shares when otherwise
permitted to sell in accordance with Article 2.9 of this Agreement.

2.11     DEFAULT ON CONTINGENT PAYMENTS.  If Purchaser fails to make a
contingent payment when due and such failure shall have remained unremedied for
a period of ten (10) business days or more after the date on which Purchaser
receives a default notice from the Sellers or any Shareholder, then (i) the
Sellers shall receive a non-exclusive license to practice the RF-ID Technology,
(ii) the Employment Agreements and Noncompete, Nonsolicitation and
Confidentiality Agreements, except for the confidentiality provisions of such
agreements, shall be null and void and of no further force or effect, (iii) the

purchase RF-ID Technology products from the Purchaser's suppliers.  Nothing in
this Article 2.11 shall relieve Purchaser of its obligations to make the
contingent payments.

                                     OF THE

The Sellers and the Shareholders, jointly and severally, hereby represent,

         business is now conducted. Each Seller is duly licensed, qualified or
         domesticated as a foreign corporation in the jurisdictions disclosed
         on Schedule 3.1.1, which are all jurisdictions where the character of
         the property owned by them or the nature of the business transacted by
         them makes such license, qualification or domestication necessary,
         except where the lack of qualification would not have a Material
         Adverse Effect.  For purposes of this Agreement, the term "Material
         Adverse Effect" shall mean an act, omission or a circumstance of any
         kind whatsoever that has a material and adverse effect on the
         business, financial condition, operations, results of operations or
         future prospects of the Sellers.

         3.1.2   EXECUTION AND ENFORCEABILITY.  The Sellers have full corporate
         power and authority to enter into and perform this Agreement and each
         other agreement, instrument, and document required to be executed by
         the Sellers in connection herewith.  The execution, delivery, and
         performance of this Agreement and such other agreements, instruments,
         and documents have been duly authorized by the board of directors of
         the Sellers and the Shareholders.  This Agreement has been duly and
         validly executed and delivered by the Sellers and the Shareholders and
         constitutes a valid and binding obligation of the Sellers and the
         Shareholders enforceable in accordance with its terms, except as such
         enforceability may be limited by bankruptcy, insolvency or other laws
         affecting creditors' rights generally or general principles of equity
         (regardless of whether such enforceability is considered in a
         proceeding in equity or at law).

         3.1.3   ABSENCE OF RESTRICTIONS AND CONFLICTS.  Except as disclosed on
         Schedule 3.1.3, the execution, delivery and performance of this
         Agreement, the consummation of the transactions contemplated by this
         Agreement and the fulfillment of and compliance with the terms and
         conditions of this Agreement do not, with or without the passing of
         time or the giving of notice or both, violate or conflict with,
         constitute a breach of or default under, result in the loss of any
         benefit under, or permit the acceleration of any obligation under, (a)
         any term or provision of the charter documents or bylaws of the
         Sellers, (b) any judgment, decree or order of any court or

         local statute, law, rule or regulation applicable to the Sellers or
         the Shareholders, or (d) any instrument, contract or other agreement
         to which the Sellers or any Shareholder is a party, or by which any of
         them or any of their respective properties is bound, or result in the
         creation of any lien, security interest, charge, or encumbrance upon
         any of such properties.

         3.1.4   CONSENTS AND APPROVALS.  To the knowledge of the Sellers and
         the Shareholders, no filing with, and no permit, authorization,
         consent or approval of any governmental authority or any other person
         is necessary for the consummation by the Sellers or the Shareholders
         of the transactions contemplated by this Agreement, including, without
         limitation, any actions or notices that must be filed by any party to
         this Agreement pursuant to the bulk sales laws of the State of
         Virginia.

         3.1.5   LEGAL PROCEEDINGS; COMPLIANCE WITH LAWS.  Except as disclosed
         on Schedule 3.1.5, there are no suits, actions, claims, proceedings or

         administrative or governmental body.  No inquiry, action, or
         proceeding has been asserted, instituted or, to the best knowledge of

         the carrying out of the transactions contemplated by this Agreement or
         to challenge the validity of such transactions or any part thereof or
         seeking damages on account thereof.  To the knowledge of the Sellers
         and the Shareholders, there is no basis for any such valid claim or
         action or any other claims or actions which would, or could reasonably
         be expected to (individually or in the aggregate), have a Material
         Adverse Effect on the business, operations, or financial condition of
         the Sellers or result in a material liability of the Sellers.  The
         Sellers are not and have not been in violation of any applicable
         local, state or federal law, ordinance, regulation, order or decree or
         any other requirement of any governmental body, agency, authority or
         court other than a violation which would reasonably not be expected to
         have a Material Adverse Effect on the Sellers.  The Sellers have all

         infringe upon any Proprietary Rights of any third party.  Except as
         set forth on Schedule 3.1.9, the Sellers have not granted to any third
         parties exclusive licenses or options to obtain exclusive licenses
         under any of the Intellectual Property owned by the Sellers listed on
         Schedule 3.1.9.  Except as set forth on Schedule 3.1.9, the Sellers
         have given no indemnification in connection with any patent,
         trademark, copyright or other Proprietary Right as to any product
         made, used or sold by any third party.  Except as set forth on
         Schedule 3.1.9, there are no pending or, to the knowledge of the
         Sellers and the Shareholders, threatened claims, proceedings or
         actions against the Sellers or any of its licensors that could have a
         Material Adverse Effect on the Sellers' Proprietary Rights or that
         could limit the Sellers' right to use any patent, trademark,  trade
         name, service mark or copyrighted material or to make, have made, sell
         or use any product, process, service, method, substance, part, or
         other material in connection with its business.  Except as set forth
         on Schedule 3.1.9, there is no infringement by or claim of
         infringement against any third party of any Proprietary Rights of the
         Sellers which could be likely to have a Material Adverse Effect on the
         Sellers' RF-ID Technology Business, operations, condition (financial
         or otherwise), or assets.

         3.1.10  YEAR 2000 COMPLIANCE.  The Sellers have reviewed the RF-ID
         Technology with a view to assessing whether it will, in the receipt,
         transmission, processing, manipulation, storage, retrieval,
         retransmission or other utilization of data, be vulnerable to any
         significant risk that computer hardware, software or any equipment
         containing embedded microchips used in the RF-ID Technology Business
         will not, in the case of dates or time periods occurring after
         December 31, 1999, function at least as effectively as in the case of
         dates or time periods occurring prior to January 1, 2000.  The Sellers
         have taken all action necessary to assure that there will be no
         Material Adverse Effect to the RF-ID Technology by reason of the
         advent of the year 2000.   The Sellers represent and warrant that the
         RF-ID Technology is and shall remain century compliant.  "Century
         Compliant" means that the RF-ID Technology is capable and will remain
         capable of providing accurate results using data having date ranges
         spanning the twentieth (20th) and twenty first (21st) centuries (the
         Y2K Period).  Without limiting the generality of the foregoing, the
         Sellers represent and warrant that the RF-ID Technology can currently
         and shall, during the Y2K Period, continue to (a) manage and
         manipulate data involving all dates within the Y2K Period (including
         the fact that the year 2000 is a leap year) without functional or data
         abnormality related to such dates; (b) manage and manipulate data
         involving all dates within the Y2K Period without inaccurate results
         related to such dates; (c) have user interfaces and data fields
         formatted to distinguish between dates within the Y2K Period;





                                      -13-
<PAGE>   15

         and (d) store all core application data in a format that includes
         indications of the millennium, century, and decade as well as the
         actual year.  This representation and warranty of the Sellers shall
         not be applicable in the event the RF-ID Technology is integrated with
         any other system to the extent that noncompliance or inconsistency
         with the Y2K operational representations made in this Article result
         from functionality wholly resident without the system integrated with
         the RF-ID Technology.

         3.1.11  CONTRACTS AND COMMITMENTS.

                 (a)      For purposes of this Agreement, "Contract" means any
         contract, agreement, promissory note, debt instrument, lease, license,
         commitment, arrangement, undertaking or understanding to which the
         Sellers are a party or bound or to which it or its property is
         subject, whether written or oral and including each and every
         amendment, modification or supplement to any of them. Except for
         Contracts listed on another Schedule to this Agreement, each Assumed
         Contract is listed on Schedule 3.1.11(a) of this Agreement, other than
         contracts, agreements, commitments, arrangements, undertakings or
         understandings:

                 (i)      for the purchase or rental of materials and supplies
                          by the Sellers entered into in the ordinary and usual
                          course of business which do not individually exceed
                          $5,000 (treating each purchase order as a separate
                          agreement) and which are reasonably expected to be
                          fully performed within six months of their respective
                          dates; or

                 (ii)     for the purchase of services by the Sellers entered
                          into in the ordinary and usual course of business
                          which do not individually involve an amount in excess
                          of $5,000 and which are reasonably expected to be
                          fully performed within six months of their respective
                          dates.

                 (b)      Except as set forth on Schedule 3.1.11(b), the
         Sellers have not, directly or indirectly, purchased, leased from
         others or otherwise acquired any property or obtained any services
         from, or sold, leased to others or otherwise disposed of any property
         or furnished any services to, or otherwise dealt with (except with
         respect to remuneration for services rendered as a director, officer
         or employee of the Sellers), in the ordinary course of business or
         otherwise, (i) any shareholder of the Sellers or (ii) any person, firm
         or corporation which, directly or indirectly, alone or together with
         others, controls, is controlled by or is under common control with the
         Sellers or Shareholder.  Except as set forth on Schedule 3.1.11(b),
         the Sellers do not owe any amount to, or have any contract with or
         commitment to, its Shareholders, directors, officers, employees or
         consultants (other than compensation for current services not yet due
         and payable and reimbursement of expenses arising in the ordinary
         course of business), and none of such persons owes any amount to the
         Sellers.

                 (c)      Except as set forth on Schedule 3.1.11(c), all of the
         Contracts are valid and binding, and are in full force and effect and
         are enforceable in accordance with their terms, except as such
         enforceability may be limited by bankruptcy, insolvency,
         reorganization or similar laws affecting creditor's rights generally.
         Neither the Sellers nor the Shareholders have any knowledge of any
         pending or threatened bankruptcy, insolvency or similar proceeding
         with respect to any party to any Contract, and to the knowledge of the
         Sellers and the Shareholders no event has occurred which (whether with
         or without notice, lapse of time or the happening or occurrence of any
         other event) would constitute a default thereunder by the Sellers or
         any other party thereto.  The Sellers have duly





                                      -14-
<PAGE>   16

         complied with all material provisions of every Contract to which it is
         a party and is not in default as to any such Contract. No condition or
         state of facts exists that, with notice or the passage of time, or
         both, would constitute a default by the Sellers under any Contract,
         except for Contracts the default of which would not have a Material
         Adverse Effect  on the financial condition of the Sellers.  The
         Sellers have not waived any material right under any Contract.  Except
         as set forth on Schedule 3.1.11(c), the Sellers have not guaranteed
         any obligations of any other person.

         3.1.12  BROKERS' AND FINDERS' FEES.  Except for Kabot and Associates,
         neither the Sellers nor anyone acting on its behalf has done anything
         to cause or incur any liability to any party for any brokers' or
         finders' fees or the like in connection with this Agreement or any
         transaction contemplated hereby.

         3.1.13  NONDISCLOSED PAYMENTS.  Neither the Sellers nor any of its
         officers or directors, nor anyone acting on behalf of it, have made or
         received any material payments not correctly categorized and fully
         disclosed in the books and records of the Sellers in connection with
         or in any way relating to or affecting the RF-ID Technology Business.

         3.1.14  RELATED PARTY TRANSACTIONS.  Schedule 3.1.14 of this Agreement
         sets forth every business relationship (other than normal employment
         relationships with employees other than officers, directors,
         Shareholders, and Affiliates (as defined below) or members of their
         families), between the Sellers on the one hand, and any of the Sellers
         officers, directors, employees and Affiliates, Shareholders, or
         members of their families (or any entity in which any of them has a
         material financial interest, directly or indirectly), including a
         complete and accurate description of the compensation, benefits,
         expense reimbursement and other arrangements between the Sellers and
         any such person or entity. Except as set forth in Schedule 3.1.14,
         none of such parties (other than the Sellers) own any assets which are
         used in the Sellers' business, or is engaged in any business which
         competes with the Sellers' business. As used herein, an ''Affiliate"
         shall mean any person or entity which controls the Sellers, which the
         Sellers control, or which is under common control with the Sellers.
         For purposes of the preceding sentence, the term "Control" means the
         power, direct or indirect, to direct or cause the direction of the
         management and policies of a person or entity by voting securities,
         contract or otherwise.

         3.1.15  CERTAIN CONSENTS.  To the best of Sellers' knowledge, there
         are no consents, waivers or approvals required to be executed and/or
         obtained from third parties in connection with the execution, delivery
         and performance of this Agreement and the transactions contemplated
         hereby.

         3.1.16  REPRESENTATIONS AND UNDERSTANDINGS OF THE SHAREHOLDERS AND THE
         SELLERS. Each Shareholder and Seller represents and warrants the
         following:

                 (a)      Information Regarding the Purchaser.  The Purchaser
         has delivered to each Shareholder and Sellers a true and complete copy
         of (i) Purchaser's Annual Report on Form 10-KSB for the year ended
         December 31, 1997, (ii) Purchaser's definitive proxy statement
         relating to its 1998 annual shareholders meeting and (iii) all other
         filings (other than preliminary registration and proxy statements)
         made by the Purchaser with the Securities and Exchange Commission
         between December 1, 1997 and the date hereof (collectively, the "SEC
         Documents").  In addition to the SEC Documents, the Purchaser has
         provided each Shareholder and Sellers with opportunities to become
         familiar with





                                      -15-
<PAGE>   17

         the business, financial condition, management, prospects and
         operations of the Purchaser, including reasonable opportunities to ask
         questions of, receive answers from and obtain information regarding
         the Purchaser and its business which is material to each Shareholder's
         and Sellers' investment decision.

                 (b)      Shares Not Registered; Indefinite Holding.  Each
         Shareholder has been advised by the Purchaser, and understand, that:
         (i) each Shareholder and Seller must bear the economic risk of an
         investment in the AXSI Shares for an indefinite period of time because
         the AXSI Shares have not been registered under the Securities Act of
         1933, as amended (the "Securities Act") or any applicable state
         securities laws; and (ii) the Purchaser is under no obligation to
         register the AXSI Shares under such laws.  As a result, the AXSI
         Shares must be held by the Sellers and the Shareholders until they are
         subsequently registered under applicable securities laws, or an
         exemption from such registration is available for the transfer of the
         AXSI Shares.  Accordingly, except as permitted by Article 2.9 of this
         Agreement, each Shareholder and Seller agree not to offer, sell,
         pledge, hypothecate or otherwise transfer or dispose of any of the
         AXSI Shares in the absence of an effective registration statement
         under the Securities Act and applicable state securities laws covering
         such disposition, or an opinion of counsel, satisfactory to the
         Purchaser and its counsel, to the effect that such registration is not
         required in respect of such transfer or disposition.  Each Shareholder
         and Seller represent that the AXSI Shares are being acquired solely
         for each of the Shareholder's and Seller's own account for investment
         and not with a view toward, or for resale in connection with, any
         "distribution" (as that term is used in the Securities Act and the
         Rules and Regulations thereunder) of all or any portion thereof.
         Because the AXSI Shares have not been registered under applicable
         securities laws, each  Shareholder and Seller hereby acknowledges that
         the AXSI Shares cannot be readily sold and, accordingly, the
         Shareholders may not be able to sell or dispose of the AXSI Shares for
         an indefinite period of time.

                 (c)      Legends on Certificates.  Each Shareholder and Seller
         further understand that the certificates for the AXSI Shares shall
         bear legends in substantially the following form:

                 These securities represented hereby have not been registered
         under the Securities Act of 1933, or applicable state securities laws,
         nor the securities laws of any other jurisdiction.  They may not be
         sold or transferred in the absence of an effective registration
         statement under those securities laws or pursuant to an exemption
         therefrom.

                 (d)      "Private Offering" Exemption;  Reliance on
         Representations.  The Sellers and the Shareholders understand that the
         offer and sale of the AXSI Shares are not being registered under the
         Securities Act or applicable state securities laws in reliance on the
         so-called "private offering" exemption provided by Section 4(2) of the
         Securities Act and/or Regulation D promulgated pursuant to the
         Securities Act, and similar exemptions under applicable state
         securities laws, and that the Purchaser is basing its reliance on that
         exemption in part on the representations, warranties, statements and
         agreements contained herein.

         3.1.17  REPRESENTATIONS AND WARRANTIES TRUE.  No representation or
         warranty of the Sellers or any Shareholder contained in this
         Agreement, the disclosure schedules or any other agreement,
         instrument, certificate or other writing delivered by or on behalf of
         any Shareholder or the Sellers pursuant to this Agreement or any other
         agreement or in connection with the transactions





                                      -16-
<PAGE>   18

         contemplated herein or therein contains any untrue statement of a
         material fact or omits (or will omit) to state a material fact
         necessary to make the statements contained herein and therein not
         misleading.  To the Sellers' and the Shareholders' knowledge, there is
         no  fact which adversely affects, or in the future may adversely
         affect, the assets, properties affairs, results of operations,
         condition (financial or otherwise), or prospects of the RF-ID
         Technology Business which has not been or is not disclosed in the
         Agreement, the disclosure schedules or in any other instruments,
         certificates, agreements or writing furnished to the Purchaser by or
         on behalf of the Shareholders or the Sellers pursuant to this
         Agreement or otherwise in connection with this Agreement.

                                  ARTICLE IV.
                         REPRESENTATIONS AND WARRANTIES
                                     OF THE
                                   PURCHASER

4.       REPRESENTATIONS AND WARRANTIES OF PURCHASER.  Purchaser hereby

         4.1     ORGANIZATION.  Purchaser is a corporation duly organized,
         validly existing and in good standing under the laws of the State of
         Delaware and is duly qualified to do business as a foreign corporation
         in each jurisdiction where the conduct of its business so requires,
         except where the failure to so qualify would not have a Material
         Adverse Effect on the Sellers' business, financial condition or
         results of operations taken as a whole.

         4.2     CERTAIN PROCEEDINGS. There is no pending action, arbitration,
         audit, hearing, investigation, litigation, or suit (whether civil,
         criminal, administrative, investigative, or informal) commenced,
         brought, conducted, or heard by or before, or otherwise involving, any
         governmental body or arbitrator that has been commenced against
         Purchaser and that challenges, or may have the effect of preventing,
         delaying, making illegal, or otherwise interfering with, any of the
         transactions contemplated in this Agreement.

         4.3     BROKERS AND FINDERS FEES.  Neither Purchaser nor anyone acting
         on its behalf has done anything to cause or incur any liability to any
         party for any brokers' or finders' fees or the like in connection with
         this Agreement or any transaction contemplated hereby.

         4.4     EXECUTION AND ENFORCEABILITY.  The Purchaser has full
         corporate power and authority to enter into and perform this Agreement

         executed and delivered by the Purchaser and constitutes a valid and
         binding obligation of the Purchaser enforceable in accordance with its
         terms, except as such enforceability may be limited by bankruptcy,
         insolvency or other laws affecting creditors' rights generally or
         general principles of equity (regardless of whether such
         enforceability is considered in a proceeding in equity or at law).

         4.5     ABSENCE OF RESTRICTIONS AND CONFLICTS.  The execution,
         delivery and performance of this Agreement, the consummation of the
         transactions contemplated by this Agreement and the

         fulfillment of and compliance with the terms and conditions of this
         Agreement do not, with or without the passing of time or the giving of
         notice or both, violate or conflict with, constitute a breach of or
         default under, result in the loss of any benefit under, or permit the
         acceleration of any obligation under, (a) any term or provision of the
         charter documents or bylaws of the Purchaser, (b) any judgment, decree
         or order of any court or governmental authority or agency to which the
         Purchaser is a party or by which the Purchaser or any of his
         respective properties is bound, (c) any federal, state, county or
         local statute, law, rule or regulation applicable to the Purchaser, or
         (d) any instrument, contract or other agreement to which the Purchaser
         is a party, or by which it or any of its respective properties is
         bound, or result in the creation of any lien, security interest,
         charge, or encumbrance upon any of such properties.

         4.6     AXSI SHARES.  At the time of issuance and any exchanges or
         transfers permitted by Article 2.9 of this Agreement, the AXSI Shares
         to be delivered to the Sellers pursuant to this Agreement will be duly
         authorized, validly issued, fully paid, nonassessable, free of any
         liens or encumbrances, and not subject to any preemptive rights or
         rights of first refusal created by statute or the Certificate of
         Incorporation or Bylaws of Purchaser or any contract or arrangement.
         The AXSI Shares will be issued in compliance with all applicable
         federal and state securities laws.  The Purchaser has all requisite
         corporate authority to issue the AXSI Shares to the Sellers.

         4.7     CERTAIN CONSENTS.  To the best of the Purchaser's knowledge,
         there are no consents, waivers or approvals required to be executed
         and/or obtained from third parties in connection with the execution,
         delivery and performance of this Agreement and the transactions
         contemplated hereby.

         4.8     NASDAQ LISTING.  The Purchaser's common stock is currently
         listed on the Nasdaq SmallCap Market and the Purchaser is currently in
         compliance with the listing requirements of the Nasdaq SmallCap Market
         which are applicable to the Purchaser.

         4.9     CAPITAL RESOURCES.  The Purchaser will continue to seek
         working capital resources to satisfy its working capital requirements.
         However, there can be no assurances and the Purchaser is not making
         any representations or warranties, that the Purchaser will be
         successful in securing any such funding on terms satisfactory to the
         Company, or any terms.

                                   ARTICLE V.
                   CONDITIONS TO OBLIGATIONS OF THE PURCHASER

5.       CONDITIONS TO OBLIGATIONS OF THE PURCHASER.  All obligations of the
Purchaser hereunder to consummate the transactions contemplated herein at the
Closing are subject to the fulfillment and satisfaction of each of the
following conditions on or prior to the Closing by the Sellers and the
Shareholders, any or all of which may be waived in whole or in part by the
Purchaser, provided that no such waiver shall be effective unless it is set
forth in a writing executed by the Purchaser.

         5.1     REPRESENTATIONS AND WARRANTIES.  The representations and
         warranties of the Sellers and the Shareholders contained in this

                                INDEMNIFICATION

         7.1     INDEMNIFICATION OBLIGATIONS.  From and after the date hereof,
and subject to the limitations and conditions set out herein, the Shareholders
and the Sellers shall indemnify and hold harmless the Purchaser, its
subsidiaries and affiliates, and each of their respective officers, directors,
employees, agents and representatives and each of the heirs, executors,
successors and assigns of any of the foregoing (collectively, the "Purchaser
Indemnified Parties") from, against and in respect of any and all claims,
liabilities, obligations, losses, costs, expenses, penalties, fines and other
judgments (at equity or at law) and damages (including, without limitation,
amounts paid in settlement, costs of investigation and reasonable attorneys'
fees and expenses) by reason of, or arising out of:

                 (a)      any breach or inaccuracy of any representation,
warranty, covenant, agreement or undertaking made by any Shareholder or the
Sellers in this Agreement or in any other agreement or certificate delivered by
any Shareholder or the Sellers to the Purchaser in connection with the matters
contemplated hereby or pursuant to the provisions hereof;

                 (b)      all liabilities and obligations of, or claims,
demands or actions against, the Purchaser or the RF-ID Technology Assets of any
nature whatsoever, whether known or unknown, accrued, absolute, contingent or
otherwise, existing as of the date hereof, which are not disclosed in this
Agreement or the Schedules to this Agreement, including, without limitation:
(i) any tax liabilities (to the extent not so reflected or reserved against)
accrued in respect of, or measured by the Sellers' income for any period or

claims or liabilities arising out of any act or omission of the Sellers or any

defective, or allegedly defective, goods or services; and

                 (c)      all liabilities or obligations of, or any claims,

losses, costs, expenses, penalties, fines and





                                      -21-
<PAGE>   23

damages of the Purchaser Indemnified Parties described in this Section as to
which the Purchaser Indemnified Parties are entitled to indemnification are
hereinafter collectively referred to as "Purchaser Losses."

         7.2     INDEMNIFICATION PROCEDURES.

                 (a)      Promptly after receipt by a Purchaser Indemnified
Party of notice by a third party of any complaint or the commencement of any
action or proceeding with respect to which indemnification is being sought
hereunder, such Purchaser Indemnified Party shall notify the Sellers and the
Shareholders of such complaint or the commencement of such action or
proceeding; provided, however, that the failure to so notify the Shareholders
and the Sellers shall relieve the Shareholders and the Sellers from liability
which the Shareholders and the Sellers may have hereunder with respect to such
claim if, but only if, and only to the extent that, such failure to notify the
Shareholders and the Sellers results in the forfeiture by or prejudice to the
Shareholders and the Sellers of rights and defenses otherwise available to the
Shareholders and the Sellers with respect to such claim.  The Shareholders and
the Sellers shall each have the right, upon written notice to the Purchaser
Indemnified Party, to assume the defense of such action or proceeding,
including the employment of counsel reasonably satisfactory to the Purchaser
Indemnified Party and the payment of the fees and disbursements of such
counsel, unless the Purchaser Indemnified Party shall have been advised by
counsel that representation of the Purchaser Indemnified Party and the
Shareholders and the Sellers by the same counsel would be inappropriate due to
differing interests.  In the event, however, that the Shareholders and the
Sellers decline or fail to assume the defense of the action or proceeding or to
employ counsel reasonably satisfactory to the Purchaser Indemnified Party, in
either case within ten (10) business days of receiving notice of a claim
against the Purchaser Indemnified Party, or in the event that counsel to the
Purchaser Indemnified Party shall have advised it that representation by the
Shareholders' and the Sellers' counsel is inappropriate then such Purchaser
Indemnified Party may employ counsel to represent or defend it in any such
action or proceeding and the Shareholders and the Sellers shall pay the
reasonable fees and disbursements of such counsel as incurred; provided,
however, that the Shareholders and the Sellers shall not be required to pay the
fees and disbursements of more than one counsel for all Purchaser Indemnified
Parties in any jurisdiction in any single action or proceeding.  In any action
or proceeding with respect to which indemnification is being sought hereunder,
the Purchaser Indemnified Party or the Shareholders and the Sellers, whichever
is not assuming the defense of such action, shall have the right to participate
in such litigation and to retain its own counsel at such party's own expense.
The Shareholders and the Sellers or the Purchaser Indemnified Party, as the
case may be, shall at all times use reasonable efforts to keep the other party
reasonably apprised of the status of the defense of any action, the defense of
which it is maintaining, and such other party shall cooperate in good faith
with the Shareholders and the Sellers or the Purchaser Indemnified Party, as
the case may be, with respect to the defense of any such action.
Notwithstanding the terms of this Section 7.2, the Sellers or the Shareholders
may pursue any claim against a third party with respect to which
indemnification is being sought hereunder, if the Sellers or the Shareholders
first pays to the Purchaser the full amount of the claim for Purchaser Losses
asserted by the Purchaser.

                 (b)      No Purchaser Indemnified Party may settle or
compromise any claim or consent to the entry of any judgment with respect to
which indemnification is being sought hereunder without the prior written
consent of Shareholder, unless such settlement, compromise or consent includes
an unconditional release of the Sellers and each Shareholder from all liability
arising out of such claim or unless the Sellers and each Shareholder has failed
to assume the defense of the action or proceeding.  Neither the Sellers or any
Shareholder may, without the prior written consent of the Purchaser Indemnified
Party, settle or compromise any claim or consent to the entry of any judgment
with respect to which indemnification is being sought





                                      -22-
<PAGE>   24

hereunder unless such settlement, compromise or consent includes an
unconditional release of the Purchaser Indemnified Party from all liability
arising out of such claim and does not contain any equitable order, judgment or
term which in any manner affects, restrains or interferes with the business of
the Purchaser Indemnified Party or any of the Purchaser Indemnified Party's
respective affiliates.

         7.3     PAYMENT.  Subject only to the $20,000 threshold set forth in
Section 7.4 below, the Purchaser may proceed against the Purchase Price to
satisfy any claims for Purchaser Losses prior to the first anniversary of the
Closing, including any claims which are asserted before the first anniversary
of the Closing, but not resolved prior to that date; provided, however, that a
promissory note in an amount not to exceed $85,000, which Sellers intend to
assign to the Juliet E. Briggs Trust, the successor-in-interest by assignment
from Mortgage One Financial Centers, Inc. in satisfaction of certain
obligations of the Sellers to such party shall not be available to the
Purchaser to satisfy claims for Purchaser Losses.  From and after the first
anniversary of the Closing, however, the Purchaser may only satisfy claims for
Purchaser Losses by reducing the balance of the contingent payments, unless
the` Sellers or the Shareholders object to such claims in the manner provided
in this Agreement.  After the third anniversary of the Closing Date, Purchaser
may only proceed against the Shareholders and the Sellers for any claim for
Purchaser Losses relating to the representations and warranties set forth in
Sections 3.1.8, 3.1.9, 3.1.10 and 3.1.11 of this Agreement if the balance of
the contingent payments which are due the Sellers are insufficient to satisfy
Purchaser Losses for those claims.  If the Sellers or any Shareholder objects
to any claim made by the Purchaser under this Agreement, the matter shall be
resolved by arbitration in accordance with the terms of this Agreement, as the
case may be.

         7.4     LIMITATION OF INDEMNIFICATION.  The indemnification by the
Shareholders and the Sellers and their respective liabilities under this
Agreement shall be limited as follows: (i) the Purchaser shall not be entitled
to any payment from the Shareholders or the Sellers under the indemnification
set forth in this Agreement unless and until the total claims for the Purchaser
under the indemnification equal or exceed TWENTY THOUSAND DOLLARS ($20,000), at
which point the Purchaser shall be entitled to claim for indemnification
dollar-for-dollar for all such damages in excess of $20,000; and (ii) after the
first anniversary date of the Closing Date, only the amount of any future
contingent payments shall be available to satisfy claims for Purchaser Losses
unless any such claim is asserted by Purchaser relating to a breach of the
representations and warranties set forth in Sections 3.1.8, 3.1.9, 3.1.10 and
3.1.11 of this Agreement.

         7.5     SURVIVAL OF REPRESENTATIONS AND WARRANTIES.  The
representations, warranties, covenants, agreements and indemnifications made by
each of the parties contained in this Agreement or in any writing delivered
pursuant to the provisions of this Agreement shall survive the investigation
heretofore or hereafter made by the Purchaser and the consummation of the
transactions contemplated herein and shall continue in full force and effect
for the period (the "Survival Period") beginning on the Closing Date and
continuing and including the first business day after the expiration of three
(3) years from and after the Closing date; provided that, representations and
warranties contained in Sections 3.1.8, 3.1.9, 3.1.10 and 3.1.11 shall survive
for the period of the applicable statute of limitations.  The survival period
shall be extended automatically to include any time period necessary to resolve
a claim for indemnification which was made before expiration of the Survival
Period but not resolved prior to its expiration; provided, however, that any
such extension shall apply only as to claims asserted and not so resolved
within the Survival Period.  Without limiting the generality of the foregoing,
the Sellers and the Shareholders each specifically acknowledge that the
representations, warranties, covenants and agreements set forth herein are not
affected in any way by Purchaser's review of any of the Sellers' minute books,
stock books or corporate records of any sort, by any





                                      -23-
<PAGE>   25

prior discussions among Purchaser, the Sellers and the Shareholders or by any
investigation heretofore or hereafter made by, or on behalf of, Purchaser.

party of the performance of any act shall not constitute a waiver of the
performance of any other act or an identical act required to be performed at a
later time.

         8.10    ARBITRATION; LEGAL PROCEEDINGS.

                 (a)      Except as provided in Article 2, the parties shall
         attempt in good faith to resolve any dispute arising out of or
         relating to this Agreement, the breach, termination or validity hereof
         or the transactions contemplated herein promptly by negotiation
         between the Shareholders and a representative of Purchaser and Sellers
         who has authority to settle the controversy. Either the Shareholder,
         Sellers or Purchaser may give the other written notice that a dispute
         exists (a "Notice of Dispute"). The Notice of Dispute shall include a
         statement of such party's position and, in the case





                                      -25-

         of Purchaser and Sellers, the name and title of the representative who
         will represent the Purchaser and the Sellers. Within ten (10) days of
         the delivery of the Notice of Dispute, the Shareholders and the
         executive representing Purchaser and the Sellers shall meet at a
         mutually acceptable time and place, and thereafter as long as they
         reasonably deem necessary, to attempt to resolve the dispute. All
         documents and other information or data on which each party relies
         concerning the dispute shall be furnished or made available on
         reasonable terms to the other party at or before the first meeting of
         the parties as provided by this paragraph.

                 (b)      Except as provided in Article 2, any controversy or
         claim arising out of or relating to this Agreement, the breach,
         termination or validity hereof, or the transactions contemplated
         herein, if not settled by negotiation as provided in paragraph (a) of
         this Article 8.10, shall be settled by arbitration in accordance with
         the Commercial Arbitration Rules ("CAR") of the American Arbitration
         Association ("AAA"), by three arbitrators from the AAA panel of
         arbitrators.  Either party may initiate arbitration twenty (20) days
         following the delivery of a Notice of Dispute if the dispute has not
         then been settled by negotiation, or sooner if the other party fails
         to participate in negotiation in accordance with paragraph (a) above.
         The three arbitrators shall be appointed as provided by the CAR,
         Selection of Arbitrators by the parties. The arbitration procedure
         shall be governed by the United States Arbitration Act, 9 U.S.C.
         Section 1-16, and the award rendered by the arbitrator shall be final
         and binding on the parties and may be entered in any court having
         jurisdiction thereof, subject to the court's authority to modify or
         review the award as provided in the Act.

                 (c)      It is the intent of the parties that any arbitration
         shall be concluded as quickly as reasonably practicable. Unless the
         parties otherwise agree, once commenced, the hearing on the disputed
         matters shall be held four days a week until concluded, with each
         hearing date to begin at 9:00 a.m. and to conclude at 5:00 p.m. The
         arbitrators shall use all reasonable efforts to issue the final award
         or awards within a period of five business days after closure of the
         proceedings. Failure of  the arbitrators to meet the time limits of
         this Section 8.10(c) shall not be a basis for challenging the award.

                 (d)      Each party shall bear its own costs and pay one-half
         of the fees and expenses of the arbitrators.

         8.11    RELIANCE ON COUNSEL AND OTHER ADVISORS.  Each party has
consulted such legal, financial, technical or other experts as it deems
necessary or desirable before entering into this Agreement. Each party
represents and warrants that it has read, knows, understands and agrees with
the terms and conditions of this Agreement.

         8.12    INJUNCTIVE RELIEF.  The parties to this Agreement hereby agree
that any remedy at law for any breach of the provisions contained in this
Agreement shall be inadequate and that any party, to the extent permitted by
applicable law, shall be entitled to injunction relief in addition to any other
remedy such party might have under this Agreement.

         8.13    SEVERABILITY.  If a judicial or arbitral determination is made
that any of the provisions of this Agreement constitutes an unreasonable or
otherwise unenforceable restriction against the Sellers or the Shareholders,
the provisions of this Agreement shall be rendered void only to the extent that
such judicial or arbitral determination finds such provisions to be
unreasonable or otherwise unenforceable with respect





                                      -26-

to Shareholders or the Sellers.  In this regard, the parties hereby agree that
any judicial or arbitral authority construing Article 2 of this Agreement shall
be empowered to sever any portion of the Territory, any prohibited business
activity or any time period from the coverage of this Agreement and to apply
the provisions of Article 2 of this Agreement to the remaining portion of the
Territory, the remaining business activities and the remaining time period not
so severed by such judicial or arbitral authority.   The time period during
which the prohibitions set forth in Sections 2.4, 2.5, 2.6 and 2.7 of this
Agreement shall apply shall be tolled and suspended with respect to the Sellers
and the Shareholders for a period equal to the aggregate quantity of time
during which the Sellers and the Shareholders violate such prohibitions in any
respect.


         IN WITNESS WHEREOF, each of the parties hereto has executed this
Agreement.
