        <footnote id="F1">Mr. Rosenblum became a director of ActiveCare, Inc. (the &quot;Company&quot;) on December 11, 2017.</footnote>
        <footnote id="F2">Pursuant to entering into a certain Securities Purchase Agreement dated December 11, 2017 (the &quot;SPA&quot;) with the Company, Mr. Rosenblum was issued a promissory note (the &quot;Note&quot;) by the Company for a principal sum of $52,631.58 due and payable within six months from issuance. In connection with entering into the SPA and purchase of the Note, the Company issued Mr. Rosenblum a warrant (the &quot;Warrant&quot;) to purchase common stock exercisable within five years of the Initial Exercise Date (as defined in the Warrant) as subject to adjustment, with an exercise price per share of Common Stock which shall be the lesser of (i) 80% of the per share price of common stock in the Private Placement (as defined therein), (ii) $3.00 per share, (iii) 80% of the unit, price offering price in the Private Placement (if applicable), or (iv) 80% of the exercise price of any warrants issued in the Private Placement, in each case subject to adjustment hereunder.</footnote>
        <footnote id="F3">The aggregate exercise price of the Warrant is $50,000. If the Company fails to repay the balance due under the Note on its maturity Mr. Rosenblum has the right, to convert all or part of the outstanding and unpaid principal sum and accrued interest (and any other fees) into shares of fully paid and non-assessable shares of Common Stock of the Company pursuant to the following conversion formula: number of shares receivable upon conversion equals the dollar amount being converted divided by the Conversion Price. The Conversion Price is the lesser of $3.00 (subject to adjustment for stock splits) or 60% of the lowest trade price in the 25 trading days.</footnote>
