AGREEMENT AND PLAN OF MERGER

This Agreement and Plan of Merger (this "Agreement") is made and entered into as of November 1, 2001, by and among Applied Digital Solutions, Inc., a Missouri corporation ("ADSX "), Digital Angel Corporation, a Delaware corporation and wholly owned subsidiary of ADSX ("DA"), Medical Advisory Systems, Inc., a Delaware corporation ("MAS"), and Acquisition Subsidiary, Inc., a Delaware corporation and wholly owned subsidiary of MAS ("Acquisition Subsidiary").

Recitals

A. ADSX currently owns approximately 16.5% of the issued and outstanding capital stock of MAS and is now the single largest stockholder in MAS. ADSX currently controls two of the seven board seats of the Board of Directors of MAS. ADSX and MAS have discussed and considered the benefits to their respective stockholders of the transactions contemplated by this Agreement. The Board of Directors of MAS has appointed a Special Committee of Directors for purposes of considering the transactions contemplated by this Agreement.

B. The Board of Directors of MAS and the Board of Directors of ADSX have analyzed and determined that the value of DA and the Other Subsidiaries (herein defined) is approximately $150,000,000, which equates to a value of each share of the issued and outstanding capital stock of MAS of $8, prior to the effect of outstanding DA Options (herein defined), notwithstanding the current market price of such stock.

C. The Board of Directors of MAS has approved and deems it advisable and in the best interests of MAS and its stockholders to consummate (i) the merger of Acquisition Subsidiary with and into DA provided for herein (the "Merger"), pursuant to which the issued and outstanding shares of DA owned by ADSX will be converted into 18,750,000 shares of MAS common stock, and (ii) the contribution by ADSX of its ownership interest in the common stock of certain subsidiaries of ADSX, as set forth in Exhibit A hereto and incorporated herein by reference (collectively the "Other Subsidiaries"), to MAS (the "Contribution") (the Merger and the Contribution, collectively, the "Transaction"), upon the terms and subject to the conditions set forth herein. The Boards of Directors of Acquisition Subsidiary, ADSX and DA have approved and deem it advisable and in the best interests of their respective companies and their respective stockholders to consummate the Merger and the Contribution upon the terms and subject to the conditions set forth herein. The Special Committee of the Board of Directors of MAS has determined that the Transaction and the Transaction Consideration (as defined below) are fair to the stockholders of MAS excluding the stockholders set forth on Exhibit B (the "Interested Stockholders") (the stockholders of MAS excluding the Interested Stockholders are referred to herein as the "Public Stockholders").

D. For federal income tax purposes, it is intended that the Merger be treated as a reorganization under Section 368 of the Internal Revenue Code of 1986, as amended, and the rules and regulations promulgated thereunder (the "Code") and that the Contribution be treated as a tax free contribution under Section 351 of the Code.

E. ADSX, DA, MAS and Acquisition Subsidiary desire to make certain representations, warranties, covenants and agreements in connection with the Transaction.

NOW, THEREFORE, in consideration of the foregoing, and of the representations, warranties, covenants and agreements contained herein, the parties hereto agree as follows:

The date on which the Closing occurs is hereinafter referred to as the "Closing Date."

(d) As soon as practicable following the Closing, the parties shall (i) file with the Secretary of State of Delaware a certificate of merger with respect to the Merger (the "Certificate of Merger") in such form as is required by and executed in accordance with the DGCL and (ii) make all other filings or recordings required under the laws of Delaware in order to effect the purposes of this Agreement. The Merger shall become effective at the date and time of the filing of the Certificate of Merger (or such other date and time as may be agreed to by ADSX and MAS and specified in the Certificate of Merger as may be permitted by the DGCL). The consummation of the Contribution shall be conditioned on the consummation of the Merger. The time at which the Merger becomes effective is referred to in this Agreement as the "Effective Time."

The officers of DA immediately prior to the Effective Time shall continue as the officers of the Surviving Corporation and after the Effective Time until such time as their successors shall be duly elected or appointed in accordance with the laws of Delaware or until their earlier death, resignation or removal.

1.3. Articles of Incorporation and Bylaws. The articles of incorporation and bylaws of DA immediately prior to the Effective Time shall be the articles of incorporation and bylaws of the Surviving Corporation as of the Effective Time.

1.4. Certificate of MAS. Immediately prior to or at the Effective Time, and subject to the terms and conditions of this Agreement and the DGCL, MAS shall cause the Amended and Restated Certificate of Incorporation of MAS to be amended and restated to change the name of MAS to "Digital Angel Corporation" and to increase the number of authorized shares of common stock to 95,000,000 shares by filing appropriate documentation (the "MAS Charter Amendment") with the Secretary of State of the State of Delaware.

ARTICLE II.

AND DA

2.1. MAS Common Stock. Each share of the common stock of MAS outstanding immediately prior to the Effective Time shall be unaffected by the Merger.

2.2. Conversion of DA Stock. (a) Subject to the provisions of this Agreement, pursuant to the Merger, at the Effective Time each issued and outstanding share of common stock, par value $.00005 per share, of DA ("DA Common Stock"), shall be immediately converted into 0.9375 fully paid, nonassessable and newly issued shares of MAS common stock, $0.005 par value ("MAS Common Stock"), or an aggregate of 18,750,000 shares of MAS Common Stock (assuming no exercise of DA Options prior to the Closing), free and clear of all security interests, claims and restrictions. The shares of MAS Common Stock to be issued to ADSX in the Merger shall be referred to as the "Transaction Consideration." As a result of the issuance of Transaction Consideration, MAS shall become a majority owned subsidiary of ADSX and the Surviving Corporation and the Other Subsidiaries shall become subsidiaries of MAS and second-tier subsidiaries, of ADSX.

2.4 Conversion of Acquisition Subsidiary Stock. At the Effective Time, by virtue of the Merger and without any action on the part of any of the parties, each share of the common stock of Acquisition Subsidiary outstanding immediately prior to the Effective Time shall become one share of common stock of the Surviving Corporation of the Merger.

REPRESENTATIONS AND WARRANTIES OF MAS

MAS represents and warrants to ADSX that the statements contained in this Article III are true and correct, except as set forth in the disclosure schedule delivered by MAS to ADSX and attached hereto and incorporated herein by reference (the "MAS Disclosure Schedule") or as otherwise expressly contemplated by this Agreement.

3.1. Organization and Good Standing. MAS is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware. Each of the subsidiaries of MAS, including Acquisition Subsidiary (each an "MAS Subsidiary" and collectively, the "MAS Subsidiaries"), is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation. Each of MAS and the MAS Subsidiaries is qualified to do business as a foreign corporation in each jurisdiction in which the failure to be so qualified would have an MAS Material Adverse Effect. For purposes of this Agreement, "MAS Material Adverse Effect" shall mean a material adverse effect on (i) the business, assets, condition (financial or otherwise), properties, liabilities, or the results of operations of MAS and the MAS Subsidiaries, taken as a whole, provided, however, that no change or effect arising out of or in connection with or resulting from any of the following shall be deemed by it or by themselves, either alone or in combination, to constitute or contribute to an MAS Material Adverse Effect: (A) general economic conditions or changes therein, (B) financial market conditions or fluctuations, or (C) any action, change, effect, circumstances or condition expressly required by this Agreement or directly and demonstrably attributable to the execution, performance or announcement of this Agreement or the transactions contemplated hereby; (ii) the ability of MAS or Acquisition Subsidiary to perform its obligations set forth in this Agreement; or (iii) the ability of MAS or Acquisition Subsidiary to timely consummate the transactions contemplated by this Agreement. MAS and the MAS Subsidiaries have all corporate power and all governmental licenses, authorizations, consents and approvals required to carry on their respective businesses as now being conducted and necessary to own, operate and lease their properties and assets except where the failure to have such power, licenses, authorizations, consents and approvals would not have an MAS Material Adverse Effect.

3.2. Capitalization. As of the date hereof, the authorized capital stock of MAS consists of 10,000,000 shares of MAS Common Stock and 1,000,000 shares of preferred stock, par value $1.75 per share. Of such authorized shares, as of the date hereof, there are issued and outstanding 5,121,230 shares of MAS Common Stock, 50,000 shares of MAS Common Stock are issued and held in the treasury of MAS, no shares of preferred stock have been designated or issued, or are outstanding and no other capital stock of MAS is issued or outstanding.

Of such authorized shares, as of the date hereof, there are issued and outstanding 10 shares of Acquisition Subsidiary Common Stock, no shares of Acquisition Subsidiary Common Stock are issued and held in the treasury of MAS and no other capital stock of Acquisition Subsidiary is issued or outstanding. All issued and outstanding shares of MAS Common Stock and Acquisition Subsidiary Common Stock are duly authorized, validly issued and outstanding, fully paid and nonassessable and were issued free of preemptive rights in compliance with applicable corporate and securities Laws (as hereinafter defined). Except as set forth in the MAS Disclosure Schedule, as of the date hereof there are no outstanding rights, including stock appreciation rights, subscriptions, warrants, puts, calls, unsatisfied preemptive rights, options or other agreements of any kind relating to, or the value of which is tied to the value of, any of the outstanding, authorized but not issued, unauthorized or treasury shares of the capital stock or any other security of MAS or Acquisition Subsidiary, and there is no authorized or outstanding security of any kind convertible into or exchangeable for any such capital stock or other security. All of the outstanding rights, including stock appreciation rights, subscriptions, warrants, puts, calls, unsatisfied preemptive rights, options or other agreements of any kind relating to, or the value of which is tied to the value of, any of the outstanding, authorized but not issued, unauthorized or treasury shares of the capital stock or any other security of MAS or Acquisition Subsidiary have been duly authorized and issued in accordance with all applicable Law. Except as set forth in the MAS Disclosure Schedule, there are no security interests, claims or restrictions upon the transfer of or otherwise pertaining to the securities (including, but not limited to, the ability to pay dividends thereon) of MAS and the MAS Subsidiaries or the ownership thereof other than those imposed by the Securities Act of 1933, as amended, and the rules and regulations thereunder (the "Securities Act"), the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (the "Exchange Act"), applicable state securities Laws or applicable corporate Law.

3.3. Subsidiaries. Each MAS Subsidiary is wholly owned by MAS and all of the capital stock and other interests of the MAS Subsidiaries so held by MAS are directly or indirectly owned by it, free and clear of any claim, lien, encumbrance, security interest or agreement with respect thereto. All of the outstanding shares of capital stock in each of the MAS Subsidiaries directly or indirectly held by MAS are duly authorized, validly issued and outstanding, fully paid and nonassessable and were issued free of preemptive rights in compliance with applicable corporate and securities Laws. There are no irrevocable proxies or similar obligations with respect to such capital stock of the MAS Subsidiaries held by MAS and no equity securities or other interests of any of the MAS Subsidiaries are or may become required to be issued or purchased by reason of any options, warrants, rights to subscribe to, puts, calls or commitments of any character whatsoever relating to, or securities or rights convertible into or exchangeable for, shares of any capital stock of any MAS Subsidiary, and there are no contracts, commitments, understandings or arrangements by which any MAS Subsidiary is bound to issue additional shares of its capital stock, or options, warrants or rights to purchase or acquire any additional shares of its capital stock or securities convertible into or exchangeable for such shares. Acquisition Subsidiary is directly and wholly owned by MAS and was recently organized under Delaware law solely for purposes of the Transaction. Acquisition Subsidiary has no assets or liabilities and has not engaged in any business or activities other than as contemplated by this Agreement.

3.4. Authorization; Binding Agreement. (a) MAS and Acquisition Subsidiary each have all requisite corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby.

This Agreement has been duly and validly executed and delivered by MAS and Acquisition Subsidiary and constitutes the legal, valid and binding agreements of MAS and Acquisition Subsidiary, enforceable against each of MAS and Acquisition Subsidiary in accordance with its terms, except to the extent that enforceability thereof may be limited by applicable bankruptcy, insolvency, reorganization or other similar laws affecting the enforcement of creditors' rights generally and by principles of equity ("Enforceability Exceptions").

(b) The only vote of any class or series of capital stock of MAS necessary to adopt or approve the Charter Amendment is a majority of the outstanding shares of MAS Common Stock. The only vote of any class or series of capital stock of MAS necessary to adopt or approve the Merger, this Agreement and the transactions contemplated by this Agreement is at least 66 2/3% of the outstanding shares of MAS Common Stock which are not owned by the Interested Stockholders.

3.5. Governmental Approvals. No consent, approval, waiver or authorization of, notice to or declaration or filing with ("Consent") any nation or government, any state or other political subdivision thereof, any person, authority or body exercising executive, legislative, judicial, regulatory or administrative functions of or pertaining to government including, without limitation, any governmental or regulatory authority, agency, department, board, commission or instrumentality, any court, tribunal or arbitrator and any self-regulatory organization ("Governmental Authority") on the part of MAS or any of the MAS Subsidiaries is required in connection with the execution or delivery by MAS of this Agreement or the consummation of the transactions contemplated hereby other than (i) the filing of the Certificate of Merger and the MAS Charter Amendment with the Secretary of State of the State of Delaware in accordance with the DGCL, (ii) the filing of the definitive Proxy Statement (as defined herein) with the Securities and Exchange Commission ("SEC"), and (iii) such other Consents the failure of which to obtain will not have an MAS Material Adverse Effect.

3.6. No Violations. The execution and delivery of this Agreement, the consummation of the transactions contemplated hereby and compliance by MAS with any of the provisions hereof will not (i) conflict with or result in any breach of any provision of the Articles and/or Certificate of Incorporation or Bylaws or other governing instruments of MAS or any of the MAS Subsidiaries, (ii) require any Consent under or result in a violation or breach of, or constitute (with or without due notice or lapse of time or both) a default (or give rise to any right of termination, cancellation or acceleration or augment the performance required) under any of the terms, conditions or provisions of any MAS Material Contract (as hereinafter defined) or other material obligation to which MAS or any MAS Subsidiary is a party or by which any of them or any of their properties or assets may be bound, (iii) result in the creation or imposition of any lien or encumbrance of any kind upon any of the assets of MAS or any MAS Subsidiary, or (iv) subject to obtaining the Consents from Governmental Authorities referred to in Section 3.5, above, contravene any applicable provision of any constitution, treaty, statute, law, code, rule, regulation, ordinance, policy or order of any Governmental Authority or other matters having the force of law including, but not limited to, any orders, decisions, injunctions, judgments, awards and decrees of or agreements with any court or other Governmental Authority ("Law") currently in effect to which MAS or any MAS Subsidiary or its or any of their respective assets or properties are subject, except in the case of clauses (ii), (iii) and (iv) above, for any deviations from the foregoing which do not or would not reasonably be expected to have an MAS Material Adverse Effect.

3.7. Securities Filings and Litigation. (a) MAS has made available to ADSX true and complete copies of (i) its Annual Reports on Form 10-K or Form 10-KSB, as amended, for the years ended October 31, 1998, 1999 and 2000, as filed with the SEC, (ii) its proxy statements relating to all of the meetings of stockholders (whether annual or special) of MAS since October 31, 1998, as filed with the SEC, and (iii) all other reports, statements and registration statements and amendments thereto (including, without limitation, Quarterly Reports on Form 10-Q or Form 10-QSB and Current Reports on Form 8-K, as amended) filed by MAS with the SEC since October 31, 1998. The reports and statements set forth in clauses (i) through (iii), above, and those subsequently provided or required to be provided pursuant to this section, are referred to collectively herein as the "MAS Securities Filings." As of their respective dates, or as of the date of the last amendment thereof, if amended after filing, none of the MAS Securities Filings (including all schedules thereto and disclosure documents incorporated by reference therein), contained or, as to MAS Securities Filings subsequent to the date hereof, will contain any untrue statement of a material fact or omitted or, as to MAS Securities Filings subsequent to the date hereof, will omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Each of the MAS Securities Filings was filed in a timely manner and at the time of filing or as of the date of the last amendment thereof, if amended after filing, complied or, as to MAS Securities Filings subsequent to the date hereof, will comply in all material respects with the Exchange Act or the Securities Act, as applicable.

(b) There is no action, cause of action, claim, demand, suit, proceeding, citation, summons, subpoena, inquiry or investigation of any nature, civil, criminal, regulatory or otherwise, in law or in equity, by or before any court, tribunal, arbitrator or other Governmental Authority ("Litigation") pending or, to the knowledge of MAS, threatened against MAS or any of its subsidiaries, any officer, director, employee or agent thereof, in his or her capacity as such, or as a fiduciary with respect to any Benefit Plan (as defined herein) of MAS or any of its subsidiaries or otherwise relating to MAS or any of its subsidiaries or the securities of any of them, or any properties or rights of MAS or any of its subsidiaries or any Benefit Plan of MAS or any of its subsidiaries which is required to be described in any MAS Securities Filing that is not so described. No event has occurred as a consequence of which MAS would be required to file a Current Report on Form 8-K pursuant to the requirements of the Exchange Act as to which such a report has not been timely filed with the SEC. Any reports, statements and registration statements and amendments thereof (including, without limitation, Annual Reports on Form 10-K or Form 10-KSB, Quarterly Reports on Form 10-Q or Form 10-QSB and Current Reports on Form 8-K, as amended) filed by MAS with the SEC after the date hereof shall be provided to ADSX on or prior to the date of such filing.

3.9. Absence of Certain Changes.

                 (b)        (1) by MAS (provided that MAS is not then in material breach of any representation, warranty, covenant or other agreement contained herein), if there has been a breach by ADSX or DA of any of their representations, warranties, covenants or agreements contained in this Agreement, or any such representation and warranty shall have become untrue, in any such case such that the conditions set forth in Section 8.2.1 or Section 8.2.2 will not be satisfied and, in either such case, such breach or condition has not been promptly cured within 30 days following receipt by ADSX of written notice of such breach; (2) by ADSX (provided that ADSX is not then in material breach of any representation, warranty, covenant or other agreement contained herein), if there has been a breach by MAS or Acquisition Subsidiary of any of its representations, warranties, covenants or agreements contained in this Agreement, or any such representation and warranty shall have become untrue, in any such case such that the conditions set forth in Section 8.3.1 or Section 8.3.2 will not be satisfied and such breach or condition has not been promptly cured within 30 days following receipt by MAS of written notice of such breach;
