Subsequent to the Merger, IBG would affect the merger of Collin Bank with and into Independent Bank, a Texas state banking association and wholly-owned subsidiary of IBG, with Independent Bank continuing as the surviving bank (the &#8220;</font><font style="font-family:inherit;font-size:12pt;font-style:italic;">Bank Merger</font><font style="font-family:inherit;font-size:12pt;">&#8221;).  </font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;"><br></font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">Pursuant to the terms of the Merger Agreement, the holders of all of the issued and outstanding shares of Collin Bank common stock (the &#8220;</font><font style="font-family:inherit;font-size:12pt;font-style:italic;">Collin Common Stock</font><font style="font-family:inherit;font-size:12pt;">&#8221;) would receive consideration equal to approximately $10.00 per share of Collin Common Stock, which would be payable approximately 65% in cash (the &#8220;</font><font style="font-family:inherit;font-size:12pt;font-style:italic;">Cash Consideration</font><font style="font-family:inherit;font-size:12pt;">&#8221;), and approximately 35% payable in shares of the common stock of IBG (the &#8220;</font><font style="font-family:inherit;font-size:12pt;font-style:italic;">IBG Merger Consideration Shares</font><font style="font-family:inherit;font-size:12pt;">&#8221;), although the aggregate number of IBG Merger Consideration Shares issued will not exceed 300,000 shares.  Based on the number of shares of Collin Bank stock currently outstanding, the amount of total consideration to be paid by Independent Bank Group is currently valued at approximately $29.1 million.  The number of IBG Merger Consideration Shares to be issued to the Collin Bank shareholders in the Merger will be determined at the effective time of the Merger, and will be calculated based upon the average of the daily average sale price per share of IBG common stock on the NASDAQ Global Market for the 20 consecutive trading days ending and including the third trading day preceding the closing date of the Merger Agreement.  The Merger Agreement sets forth certain adjustments that would occur to the amount of the Cash Consideration in the event the total number of IBG Merger Consideration Shares would exceed 300,000 shares.</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;"><br></font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">The Merger is expected to close during the fourth quarter of 2013, subject to the effectiveness of IBG&#8217;s Form S-4 Registration Statement with the Securities and Exchange Commission, the receipt of regulatory approvals, approval of Collin Bank&#8217;s shareholders, and the satisfaction of other customary closing conditions.

Moreover, the parties to the Merger Agreement may be subject to a contractual standard of materiality that may be different from what may be viewed as material to shareholders of IBG or Collin Bank or may have been used for the purpose of allocating risk between IBG, together with its direct and indirect subsidiaries, and Collin Bank rather than for the purpose of establishing matters as facts. For the foregoing reasons, no one should rely on such representations, warranties, covenants or other terms, provisions or conditions as statements of factual information regarding IBG or Collin Bank at the time they were made or otherwise. </font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;"><br></font></div><br><div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:312px;font-size:8pt;"><font style="font-family:inherit;font-size:8pt;">&#160;&#160;&#160;&#160;</font></div></div><hr style="page-break-after:always"><a name="s5AD3065EF44334BFA140F34C500822DD"></a><div></div><br><div style="line-height:120%;padding-bottom:16px;text-align:center;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;font-weight:bold;">SIGNATURES</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.</font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;"><br></font></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">Dated:  July 19, 2013.</font></div><div style="line-height:120%;padding-bottom:32px;text-align:left;text-indent:276px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">INDEPENDENT BANK GROUP, INC.</font></div><div style="line-height:120%;padding-left:282px;font-size:12pt;"><div style="padding-left:0px;text-indent:0px;line-height:normal;padding-top:10px;"><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;font-size:10pt;width:55.769230769230774%;border-collapse:collapse;text-align:left;"><tr><td colspan="2"></td></tr><tr><td width="21%"></td><td width="79%"></td></tr><tr><td style="vertical-align:top;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">By:</font></div></td><td style="vertical-align:top;border-bottom:1px solid #000000;padding-left:2px;padding-top:2px;padding-bottom:2px;padding-right:2px;"><div style="text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">/s/ David R.

Item 1.01.    Entry Into a Material Definitive Agreement.
On July 18, 2013, Independent Bank Group, Inc. ("
IBG
") entered into an Agreement and Plan of Reorganization (the "
Merger Agreement
") with Collin Bank, a Texas state banking association ("
Collin Bank
"), pursuant to which IBGCB Acquisition Corporation, a proposed Texas corporation and wholly-owned subsidiary of IBG ("
Newco
"), would merge with and into Collin Bank and Collin Bank would continue as the surviving entity (the "
Merger
").  Subsequent to the Merger, IBG would affect the merger of Collin Bank with and into Independent Bank, a Texas state banking association and wholly-owned subsidiary of IBG, with Independent Bank continuing as the surviving bank (the "
Bank Merger
").
Pursuant to the terms of the Merger Agreement, the holders of all of the issued and outstanding shares of Collin Bank common stock (the "
Collin Common Stock
") would receive consideration equal to approximately $10.00 per share of Collin Common Stock, which would be payable approximately 65% in cash (the "
Cash Consideration
"), and approximately 35% payable in shares of the common stock of IBG (the "
IBG Merger Consideration Shares
"), although the aggregate number of IBG Merger Consideration Shares issued will not exceed 300,000 shares.  Based on the number of shares of Collin Bank stock currently outstanding, the amount of total consideration to be paid by Independent Bank Group is currently valued at approximately $29.1 million.  The number of IBG Merger Consideration Shares to be issued to the Collin Bank shareholders in the Merger will be determined at the effective time of the Merger, and will be calculated based upon the average of the daily average sale price per share of IBG common stock on the NASDAQ Global Market for the 20 consecutive trading days ending and including the third trading day preceding the closing date of the Merger Agreement.  The Merger Agreement sets forth certain adjustments that would occur to the amount of the Cash Consideration in the event the total number of IBG Merger Consideration Shares would exceed 300,000 shares.
The Merger is expected to close during the fourth quarter of 2013, subject to the effectiveness of IBG's Form S-4 Registration Statement with the Securities and Exchange Commission, the receipt of regulatory approvals, approval of Collin Bank's shareholders, and the satisfaction of other customary closing conditions.  The Merger has been approved by the Boards of Directors of IBG and Collin Bank.

IBG's press release, dated July 19, 2013, announcing the proposed transaction disclosed herein is filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.
