<P STYLE="font: 13pt Garamond, Times, Serif; margin: 0">On behalf of Acacia Research Corporation (&ldquo;Acacia&rdquo;, NASDAQ: ACTG),
we are pleased to submit this proposal to acquire Spok Holdings, Inc. (&ldquo;Spok&rdquo; or the &ldquo;Company&rdquo;) for $10.75 per
share in cash, representing approximately $155 million in total enterprise value. There are no financing contingencies to our offer and
Acacia is prepared to move expeditiously to complete a transaction.</P>

<P STYLE="font: 13pt Garamond, Times, Serif; margin: 0">&nbsp;</P>

<P STYLE="font: 13pt Garamond, Times, Serif; margin: 0">Our all-cash offer represents a substantial and highly compelling premium for
shareholders that is 36.9% greater than the Company&rsquo;s unaffected closing price on August 30, 2021 and a premium of 35.0% to the
Company&rsquo;s 30-day volume-weighted average price per share as of August 30, 2021. In our view, this proposal is in the best interests
of the Company and its shareholders, and we would like to begin discussions with you on bringing Spok into the Acacia family.</P>

<P STYLE="font: 13pt Garamond, Times, Serif; margin: 0">&nbsp;</P>

<P STYLE="font: 13pt Garamond, Times, Serif; margin: 0">Acacia is a publicly traded company with a broad mandate to acquire operating
businesses in the technology, healthcare, industrial and certain financial services sectors. Acacia is well-capitalized, with more than
$780 million in available capital, including $528.5 million in cash and securities on its balance sheet and unused committed financing
of more than $255 million through our partnership with Starboard Value LP, a leading investment manager.</P>

<P STYLE="font: 13pt Garamond, Times, Serif; margin: 0">&nbsp;</P>

<P STYLE="font: 13pt Garamond, Times, Serif; margin: 0">Further, Acacia owns approximately 6.5% of the outstanding common stock of the
Company. As you know, in light of our substantial ownership stake, we are required to publicly disclose this letter and its contents.</P>

<P STYLE="font: 13pt Garamond, Times, Serif; margin: 0">&nbsp;</P>

<P STYLE="font: 13pt Garamond, Times, Serif; margin: 0">We have been studying Spok for some time and look forward to getting to know you
better as we pursue the proposed transaction.</P>
