<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Boingoites,</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">This morning, Boingo filed definitive proxy materials, and a letter to our stockholders, urging them to vote for the reelection of two important Boingo board members, Chuck Boesenberg and Terry Jones. You can find a link to the press release, which includes the full letter to our stockholders, here.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">This proxy filing contains information that responds to the &#147;Ides Group,&#148; which includes four individual stockholders and an affiliated hedge fund,&nbsp;Ides Capital. The Ides Group owns approximately 0.4% of the outstanding shares of Boingo, but is asking for their two hand-picked nominees to be named to the Boingo Board of Directors.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">We are always interested in listening to the input and ideas of our stockholders, and we have been working diligently to avoid a costly proxy fight. However, despite our best attempts, we have been unable to reach an agreement with Ides Group - who won&#146;t even allow us to interview their candidates.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="font-size:10.0pt;margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Proxy fights can result in extra attention from the press</font> and can sometimes turn negative, so don&#146;t be surprised if you see Boingo appearing in the media more frequently or see negative comments about Boingo. Most importantly, don&#146;t be distracted by what you hear or read.</p>

<p style="margin:0in 0in .0001pt;"><b><font size="2" face="Times New Roman" style="font-size:10.0pt;font-weight:bold;">Cautionary Statement Regarding Forward-Looking Statements</font></b></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">This e-mail contains &#147;forward-looking statements&#148; that involves risks, uncertainties and assumptions. Forward-looking statements can be identified by words such as &#147;anticipates,&#148; &#147;intends,&#148; &#147;plans,&#148; &#147;seeks,&#148; &#147;believes,&#148; &#147;estimates,&#148; &#147;expects&#148; and similar references to future periods. These forward-looking statements include, among other statements, any statements regarding Boingo&#146;s strategic plans and operating results and the effectiveness of Boingo&#146;s Board in overseeing the execution of Boingo&#146;s strategic plans. Forward-looking statements are based on the Company&#146;s current expectations and assumptions regarding its business, the economy and other future conditions. Since forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. The Company&#146;s actual results may differ materially from those contemplated by the forward-looking statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements include our ability to maintain our existing and establish new relationships with venue partners, particularly key airport venue partners and military bases, our ability to maintain revenue growth and achieve profitability, our ability to execute on our strategic and business plans, our ability to successfully compete with new technologies and adapt to changes in the wireless industry, as well as other risks and uncertainties described more fully in documents filed with or furnished to the Securities and Exchange Commission (SEC), including Boingo&#146;s Form&nbsp;10-K for the year ended December&nbsp;31, 2015 filed with the SEC on March&nbsp;11, 2016. Any forward-looking statement made by Boingo in this e-mail speaks only as of the date on which it is made. Factors or events that could cause the Company&#146;s actual results to differ may emerge from time to time, and it is not possible for Boingo to predict all of them. Boingo undertakes no obligation to publicly update any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law.</font></p>
