&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;LEGAL MATTERS&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;From time to time, claims are made against us in the ordinary course
of business, which could result in litigation. Claims and associated litigation are subject to inherent uncertainties and unfavorable
outcomes could occur, such as monetary damages, fines, penalties or injunctions prohibiting us from selling one or more products
or engaging in other activities.&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;The occurrence of an unfavorable outcome in any specific period could
have a material adverse effect on our results of operations for that period or future periods. Other than as mentioned here, we
are not presently a party to any pending or threatened legal proceedings.&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-indent: 0.5in"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;On July 5, 2012, Gemini Master Fund, Ltd., a Cayman Islands company
(&amp;#34;Gemini&amp;#34;), filed a complaint against the Company in the Supreme Court of the State of New York, County of New York,
entitled Gemini Master Fund Ltd. v. Aethlon Medical, Inc., Index No. 652358/2012 (the &amp;#34;Complaint&amp;#34;).&amp;#160;&amp;#160;In the
Complaint, Gemini is seeking relief both in the form of money damages and delivery of shares of the Company's common stock. The
Complaint alleges, among other things, that the Company is in default of a certain promissory note originally issued to Gemini
on February 12, 2010 by failing to pay the note in full and by failing to honor certain requests by Gemini to convert principal
and interest under the note into shares of the Company's common stock.&amp;#160;&amp;#160; The Complaint also alleges that the Company
failed to issue shares upon the presentation of an exercise notice under a warrant originally issued to Gemini on November 22,
2010. The lawsuit also alleges that the Company should have issued shares pursuant to the exercise of a warrant issued in 2009.
The Company believes that it has defenses to the claims asserted and it continues to vigorously defend the lawsuit, which is in
the late discovery stage. No trial date has yet been set. There can be no assurances, however, that the litigation will be decided
in the Company's favor as to all, or any part, of Gemini's Complaint. An adverse decision in the litigation could have an adverse
effect on the Company's operations and could be dilutive to the Company's shareholders.&lt;/p&gt;</NonNumbericText><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat></Cell></Cells><ElementDataType>nonnum:textBlockItemType</ElementDataType><SimpleDataType>na</SimpleDataType><ElementDefenition>The entire disclosure for commitments and contingencies.</ElementDefenition><ElementReferences>Reference 1: http://www.xbrl.org/2003/role/presentationRef
