      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;On

      May 23, 2011, the Company acquired all of the outstanding

      capital stock of MFS in a transaction accounted for using the

      purchase method of accounting (the

      &amp;#8220;Acquisition&amp;#8221;).&amp;#160;&amp;#160;Since MFS&amp;#8217;s

      inception, its key personnel have had an important role in

      developing technologies to automate the process of biological

      pathogen detection.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1911"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;As

      consideration for the consummation of the Acquisition, the

      Company paid $250,000 to fund certain accounts payable of MFS

      (of which approximately $24,000 was paid to selling

      shareholders) and issued 95,000 shares of common stock of the

      Company (the &amp;#8220;Stock Consideration&amp;#8221;). The Company

      issued a total of 38,857 shares of common stock in 2011 to

      its advisors for brokerage services rendered in conjunction

      with the Acquisition. The Company incurred a charge in 2011

      of approximately $550,000 related to the direct costs of the

      Acquisition, consisting of the $365,000 value of the shares

      of common stock issued to its advisors and $185,000 of cash

      costs. The Company issued an additional 18,406 shares of

      common stock to the advisors during the first quarter of

      2012, pursuant to which a charge of approximately $69,000 was

      recorded.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1913"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;In

      connection with the Acquisition, the Company is also required

      to make certain earn-out payments, up to a maximum of

      $4,000,000 payable in shares of the Company&amp;#8217;s common

      stock, upon certain conditions over 2013 and 2014 (the

      &amp;#8220;Earn-Out Payment&amp;#8221;). There was also opportunity

      for the MFS sellers to achieve Earn-Out Payments in 2011 and

      2012.&amp;#160;&amp;#160;Targets were not met in either of these two

      years.&amp;#160;&amp;#160;The earn-out for years 2013-2014 is based

      on MFS achieving certain earnings targets for the respective

      year, subject to a maximum Earn-Out Payment of $2,000,000 per

      year and an overall cumulative maximum Earn-Out Payment of

      $4,000,000.&amp;#160;&amp;#160;Additionally, approximately two-thirds

      of the earn-out is capped at $8.00 per

      share.&amp;#160;&amp;#160;Further, the Company is prohibited from

      making any Earn-Out Payment until stockholder approval is

      obtained if the aggregate number of shares to be issued

      exceeds 19.99% of the Company&amp;#8217;s common stock

      outstanding immediately prior to the closing. In the event

      the Company is unable to obtain any required stockholder

      approval, the Company is obligated to pay the applicable

      Earn-Out Payment in cash to the sellers. In addition, the

      Company may pay any Earn-Out Payment in cash at its

      option.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 40pt; MARGIN: 0pt" id="PARA1915"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;The

      estimated purchase price of the Acquisition totaled

      approximately $1,653,000, comprised of (i) $24,000 in cash,

      (ii) Stock Consideration of $879,000 based on a stock price

      of $9.25 per share, and (iii) contingent consideration of

      approximately $750,000. The fair value of the contingent

      consideration was estimated based upon the present value of

      the probability-weighted expected future payouts under the

      earn-out arrangement. On October 31, 2011, the Company

      entered into an agreement with two of the selling MFS

      shareholders pursuant to which the two individuals waived

      their right to any earn-out compensation for 2011 in

      settlement of the closing working capital adjustment

      provisions of the purchase agreement.&lt;/font&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;On

      January 11, 2012, VeriTeQ Acquisition Corporation

      (&amp;#8220;VeriTeQ&amp;#8221;), which is owned and controlled by Mr.

      Silverman, our former Chairman and Chief Executive Officer,

      purchased all of the outstanding capital stock of PositiveID

      Animal Health (&amp;#8220;Animal Health&amp;#8221;) in exchange for a

      secured promissory note in the amount of $200,000 (the

      &amp;#8220;Note&amp;#8221;) and 4 million shares of common stock of

      VeriTeQ representing a 10% ownership interest, to which no

      value was ascribed. Our chief executive officer, Mr. Caragol,

      served on the Board of Directors of VeriTeQ until July 8,

      2013.&amp;#160;The Note accrues interest at 5% per annum.

      Payments under the Note were to begin on January 11, 2013 and

      are due and payable monthly, and the Note matures on January

      11, 2015. The Note is secured by substantially all of the

      assets of Animal Health pursuant to a Security Agreement

      dated January 11, 2012 (the &amp;#8220;VeriTeQ Security

      Agreement&amp;#8221;). The Company has not recorded the Note or

      any accrued interest in its consolidated balance sheet as of

      June 30, 2013, and currently plans to recognize the $200,000

      gain represented by the Note as the Note is collected. As of

      June 30, 2013, VeriTeQ had not yet made payment on the

      Note.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1921"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;In

      connection with the sale, the Company entered into a license

      agreement with VeriTeQ (the &amp;#8220;Original License

      Agreement&amp;#8221;) which grants VeriTeQ a non-exclusive,

      perpetual, non-transferable, license to utilize the

      Company&amp;#8217;s bio-sensor implantable radio frequency

      identification (RFID) device that is protected under United

      States Patent No. 7,125,382, &amp;#8220;Embedded Bio Sensor

      System&amp;#8221; (the &amp;#8220;Patent&amp;#8221;) for the purpose of

      designing and constructing, using, selling and offering to

      sell products or services related to the VeriChip business,

      but excluding the GlucoChip or any product or application

      involving blood glucose detection or diabetes

      management.&amp;#160;&amp;#160;Pursuant to the Original License

      Agreement, the Company was to receive royalties in the amount

      of 10% on all gross revenues arising out of or relating to

      VeriTeQ&amp;#8217;s sale of products, whether by license or

      otherwise, specifically relating to the Patent, and a royalty

      of 20% on gross revenues that are generated under the

      Development and Supply Agreement between the Company and

      Medical Components, Inc. (&amp;#8220;Medcomp&amp;#8221;) dated April

      2, 2009. The total cumulative royalty payments under the

      agreement with Medcomp will not exceed $600,000.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1923"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;The

      Company also entered into a shared services agreement with

      VeriTeQ on January 11, 2012 (the &amp;#8220;SSA&amp;#8221;), pursuant

      to which the Company agreed to provide certain services,

      including administrative, rent, accounting, business

      development and marketing, to VeriTeQ in exchange for $30,000

      per month. The SSA has also included working capital advances

      from time to time.&amp;#160;The term of the Shared Services

      Agreement commenced on January 23, 2012. The first payment

      for such services was not payable until VeriTeQ receives

      gross proceeds of a financing of at least $500,000. The

      balance due from VeriTeQ under the SSA, including certain

      expenses paid by the Company on behalf of VeriTeQ, totaled

      approximately $160,000 as of May 31, 2012, which was not

      recorded in the Company&amp;#8217;s balance sheet and was to be

      recorded on a cash basis as collected. On June 25, 2012, the

      level of resources provided under the SSA was reduced and the

      agreement was amended, pursuant to which all amounts owed to

      the Company under the SSA as of May 31, 2012 were converted

      into 2,285,779 shares of common stock of VeriTeQ, to which no

      value was ascribed. In addition, effective June 1, 2012, the

      monthly charge for the shared services under the SSA was

      reduced from $30,000 to $12,000.&amp;#160;&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1925"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;On

      June 26, 2012, the Original License Agreement was amended

      pursuant to which the license was converted from a

      non-exclusive license to an exclusive license, subject to

      VeriTeQ meeting certain minimum royalty requirements as

      follows: 2013 - $400,000; 2014 - $800,000; and 2015 and

      thereafter - $1,600,000.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1927"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;On

      August 28, 2012, the Company entered into an Asset Purchase

      Agreement (&amp;#8220;APA&amp;#8221;) with VeriTeQ (the

      &amp;#8220;VeriTeQ Asset Purchase Agreement&amp;#8221;), whereby

      VeriTeQ purchased all of the intellectual property, including

      patents and patents pending, related to the Company&amp;#8217;s

      embedded biosensor portfolio of intellectual property. There

      were no proceeds received in connection with this sale and

      the intellectual property had a book value of nil. Under the

      VeriTeQ APA, the Company is to receive royalties in the

      amount of ten percent (10%) on all gross revenues arising out

      of or relating to VeriTeQ&amp;#8217;s sale of products, whether

      by license or otherwise, specifically relating to the

      embedded biosensor intellectual property, to be calculated

      quarterly with royalty payments due within 30 days of each

      quarter end. In 2012, there are no minimum royalty

      requirements. Minimum royalty requirements thereafter, and

      through the remaining life of any of the patents and patents

      pending, are identical to the minimum royalties due under the

      Original License Agreement, as amended.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1929"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;Simultaneously

      with the VeriTeQ APA, the Company entered into a license

      agreement with VeriTeQ granting the Company an exclusive,

      perpetual, transferable, worldwide and royalty-free license

      to the Patent and patents pending that are a component of the

      GlucoChip in the fields of blood glucose monitoring and

      diabetes management. In connection with the VeriTeQ APA, the

      Original License Agreement, as amended June 26, 2012, was

      terminated. Also on August 28, 2012, the VeriTeQ Security

      Agreement was amended, pursuant to which the assets sold by

      the Company to VeriTeQ under the VeriTeQ APA and the related

      royalty payments were added as collateral under the VeriTeQ

      Security Agreement.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1931"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;On

      August 28, 2012, the SSA was further amended to align with

      the level of services being provided, pursuant to which,

      effective September 1, 2012, the monthly charge for the

      shared services under the SSA was reduced from $12,000 to

      $5,000.&amp;#160; As of December 31, 2012 and June 30, 2013,

      VeriTeQ owed the Company $138,000 and $ 273,000,

      respectively, for shared services and working capital

      advances, for which no revenue has been recorded.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p id="PARA1933" style="text-align: left; line-height: 1.25; margin: 0pt;"&gt;

      &lt;font style="font-family: Times New Roman, Times, serif; font-size: 10pt;"&gt;On

      July 8, 2013, the Company entered into a letter

      agreement&amp;#160;with VeriTeQ which amended certain terms of

      the SSA, the APA, and the Secured Promissory Note dated

      January 11, 2012. The letter agreement effectively terminates

      the SSA, including a payment of $63,000 toward the current

      outstanding balance for past shared services. The letter

      agreement also eliminates minimum royalties payable to

      PositiveID under the APA, with remedies for the Company to

      recover ownership or license of the underlying patents if

      VeriTeQ fails to meet certain sales levels. Further, the

      letter agreement amended the Secured Promissory Note, which

      has a current balance of $228,000, to include a conversion

      feature under which the Note may be repaid, at

      VeriTeQ&amp;#8217;s option, in equity in lieu of cash.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; MARGIN: 0pt" id="PARA1935"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;&lt;i&gt;License

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1937"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;In

      February 15, 2013, the Company entered into an agreement the

      (&amp;#8220;SGMC Agreement&amp;#8221;) with SGMC, Easy Check,

      Easy-Check Medical Diagnostic Technologies Ltd., an Israeli

      company, and Benjamin Atkin, an individual

      (&amp;#8220;Atkin&amp;#8221;), pursuant to which the Company licensed

      its &lt;i&gt;iglucose&lt;/i&gt;&amp;#8482; technology to SGMC for up to $2

      million based on potential future revenues of glucose test

      strips sold by SGMC.&amp;#160;&amp;#160;These revenues will range

      between $0.0025 and $0.005 per strip. A person with diabetes

      who tests three times per day will use over 1,000 strips per

      year.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1939"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;Pursuant

      to the SGMC Agreement, the Company granted SGMC an exclusive

      right and license to the intellectual property rights in the

      &lt;i&gt;iglucose&lt;/i&gt; patent applications; a non-exclusive right

      and license to use and make a &amp;#8220;white label&amp;#8221;

      version of the &lt;i&gt;iglucose&lt;/i&gt; websites; a non-exclusive

      right and license to use all documents relating to the

      &lt;i&gt;iglucose&lt;/i&gt; 510(k) application to the Food and Drug

      Administration of the United States Government; and an

      exclusive right and license to the &lt;i&gt;iglucose&lt;/i&gt; trademark.

      The Company has also agreed to transfer to SGMC all right,

      title, and interest in the www.iglucose.com and

      www.iglucose.net domain names.&lt;/font&gt;

    &lt;/p&gt;&lt;br/&gt;&lt;p style="TEXT-ALIGN: left; LINE-HEIGHT: 1.25; TEXT-INDENT: 45pt; MARGIN: 0pt" id="PARA1941"&gt;

      &lt;font style="FONT-FAMILY: Times New Roman, Times, serif; FONT-SIZE: 10pt"&gt;In

      consideration for the rights and licenses discussed above,

      and the transfer of the domain names, SGMC shall pay to the

      Company the amount set forth below for each glucose test

      strip sold by SGMC and any sublicensees of SGMC for which

      results are posted by SGMC via its communications servers

      (the &amp;#8220;Consideration&amp;#8221;):&lt;/font&gt;
