Common Stock&#x201d;), of the registrant, Neighborhood Intelligence, Inc. (&#x201c;NXH&#x201d;), to
be issued upon the completion of the transactions contemplated by that certain
Agreement and Plan of Merger, dated as of June 16, 2026 (as amended by the Amendment
thereto, dated as of August 14, 2026, the &#x201c;Merger Agreement,&#x201d; and such
transactions collectively, the &#x201c;Merger&#x201d;), by and among NXH, Fathom Merger Sub,
Inc. and Fathom Holdings Inc. (&#x201c;Fathom&#x201d;). This number is estimated solely for
the purpose of calculating the registration fee and is based on (i) 36,597,960,
the estimated maximum number of shares of common stock, no par value per share
(&#x201c;Fathom Common Stock&#x201d;), of Fathom issued and outstanding or issuable or
expected to be exchanged (including in respect of Fathom restricted stock,
restricted stock units and performance stock units outstanding as of the
initial filing of this registration statement) in connection with the Merger,
multiplied by (ii) 0.2236, the initial exchange ratio under the Merger
Agreement. &lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt;&lt;table style="font-size: 12pt; border-spacing: 0px; border-collapse: collapse; width: 100%;"&gt; &lt;tr style="height: 0px; font-size: 0px;"&gt;&lt;td style="width: 1%;"&gt;&#160;&lt;/td&gt;&lt;td style="width: 99%;"&gt;&#160;&lt;/td&gt;&lt;/tr&gt;&lt;tr style="vertical-align: top;"&gt; &lt;td style="padding: 0px 0pt;"&gt; &lt;div style="margin-bottom: 4pt;"&gt;&lt;span style="font-size: 10.0pt;"&gt;(2)&lt;/span&gt; &lt;/div&gt; &lt;/td&gt; &lt;td style="padding: 0px 5.4pt; text-align: left; font-size: 10pt;"&gt; &lt;div style="margin-bottom: 4pt;"&gt; Estimated solely for
purposes of calculating the registration fee pursuant to Rules 457(c) and
457(f)(1) under the Securities Act of 1933, as amended. The proposed maximum
aggregate offering price $25,984,551.60 of the shares of NXH Common Stock was calculated based
upon the market value of shares of NXH Common Stock and is equal to the product
of (i) $0.71, the average of the high and low prices of a share of &lt;span style="mso-spacerun:yes"&gt;&#160;&lt;/span&gt;Fathom Common Stock as reported on the Nasdaq Capital
Market on August 12, 2026, and (ii) 36,597,960, the estimated maximum number of
shares of Fathom Common Stock issued and outstanding or issuable or expected to
be exchanged (including in respect of Fathom restricted stock, restricted stock
units and performance stock units outstanding as of the initial filing of this
