(f) Each of Mr. Eggemeyer, Mr. Thomas, Mr. Merlo and Mr. Pietrzak is a citizen of the United States of America.

Item 3. Source and Amount of Funds or Other Consideration

The information in Items 4 and 6 is incorporated by reference.

As more fully described in Items 4 and 6 below, on December 13, 2016, the Company entered into an Agreement and Plan of Merger (the “Original Merger Agreement”) with Eastern Virginia Bankshares, Inc. (“EVBS”), as amended by Amendment No. 1 to Agreement and Plan of Merger (“Amendment No. 1”), and as further amended by Amendment No. 2 to Agreement and Plan of Merger (“Amendment No. 2”; the Original Merger Agreement, Amendment No. 1 and Amendment No. 2 shall be collectively referred to herein as the “Merger Agreement”). On June 23, 2017, pursuant to the Merger Agreement, EVBS merged with and into the Company (the “Merger”), with the Company being the surviving corporation.

Prior to the Merger, Fund IV owned (1) 1,061,225 shares of common stock of EVBS (“EVBS Common Stock”) and (2) 4,048,670 shares of non-voting mandatorily convertible non-cumulative preferred stock, Series B, of EVBS (“EVBS Preferred Stock” and together with EVBS Common Stock, the “EVBS Shares”), all of which Fund IV acquired pursuant to a Securities Purchase Agreement, dated March 26, 2013, by and between Fund IV and EVBS (the “2013 EVBS SPA”). The EVBS Shares were acquired by Fund IV using funds obtained from Fund IV’s general and limited partners, including the other Reporting Persons.

Pursuant to the Merger Agreement, upon the effectiveness of the Merger, each share of Fund IV’s EVBS Common Stock and EVBS Preferred Stock was canceled and converted into the right to receive 0.6313 shares of SONA Common Stock. Cash was paid in lieu of fractional shares. Accordingly, Fund IV now owns 3,225,876 shares of SONA Common Stock.

The foregoing references to and descriptions of the Merger Agreement and the 2013 EVBS SPA, and the transactions contemplated thereby, do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the full text of the Merger Agreement (including its amendments), attached hereto as Exhibits 2, 3 and 4 and incorporated herein by reference, and the full text of the 2013 EVBS SPA, attached hereto as Exhibit 5 and incorporated herein by reference.

CUSIP No. 843395104

SCHEDULE 13D

Item 4. Purpose of Transaction

The information in Items 3 and 6 is incorporated by reference.

Fund IV previously acquired the EVBS Shares in the ordinary course of business because of Fund IV’s belief that the EVBS Shares represented an attractive investment in accordance with Fund IV’s investment strategy.

Subject to the limitations imposed by applicable federal and state securities laws, the Reporting Persons may dispose of the SONA Common Stock from time to time, subject to market conditions and other investment considerations, and may cause the SONA Common Stock to be distributed in kind to investors. To the extent permitted by applicable bank regulatory limitations, each Reporting Person may directly or indirectly acquire additional shares of SONA Common Stock or associated rights or securities exercisable for or convertible into SONA Common Stock, depending upon an ongoing evaluation of its investment in the SONA Common Stock and securities exercisable for or convertible into SONA Common Stock, applicable legal restrictions, prevailing market conditions, liquidity requirements of such Reporting Person and/or investment considerations.

To the extent permitted under the passivity commitments that Fund IV has provided to the Board of Governors of the Federal Reserve System (the “Federal Reserve”) described in Item 6 below, and applicable laws, the Reporting Persons may engage in discussions with management, the Company’s board of directors, other stockholders of the Company and other relevant parties concerning the business, operations, composition of the board of directors, management, strategy and future plans of the Company.

The foregoing references to and descriptions of the Merger Agreement and the transactions contemplated thereby do not purport to be complete and are subject to, and are qualified in their entirety by reference to, the full text of the Merger Agreement (including its amendments), attached hereto as Exhibits 2, 3 and 4 and incorporated herein by reference.

Other than as described in this Item 4, each of the Reporting Persons has no present plans or proposals that relate to or would result in any of the events set forth in Items 4(a) through (j) of Schedule 13D. However, each of the Reporting Persons reserves the right to change its plans at any time, as it deems appropriate, in light of its ongoing evaluation of (i) its business and liquidity objectives; (ii) the Company’s financial condition, business, operations, competitive position, prospects and/or share price; (iii) industry, economic and/or securities markets conditions; (iv) alternative investment opportunities; and (v) other relevant factors.

(e) N/A.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

The information set forth in Items 3 and 4 is incorporated herein by reference.

On December 13, 2016, the Company and EVBS entered into the Merger Agreement. On June 23, 2017, pursuant to the Merger Agreement, EVBS merged with and into the Company, with the Company being the surviving corporation. Upon the effectiveness of the Merger, each of the 1,061,225 shares of EVBS Common Stock and 4,048,670 shares of EVBS Preferred Stock owned by Fund IV was canceled and converted into 0.6313 shares of SONA Common Stock. Cash was paid in lieu of fractional shares. Accordingly, Fund IV now owns 3,225,876 shares of SONA Common Stock.

The following is a description of certain rights and restrictions applicable to Fund IV.

Board Representation. Pursuant to the 2013 EVBS SPA, Fund IV was entitled to designate one person (the “Board Representative”) for election to the board of directors of EVBS and the board of directors of the Company’s banking subsidiary (“EVB”), for so long as Fund IV and its affiliates beneficially owned at least 5% of the outstanding shares of Common Stock (as calculated pursuant to the 2013 EVBS SPA) (the “Qualifying Ownership Interest”). The 2013 EVBS SPA also provided that for so long as Fund IV and its affiliates in the aggregate owned a Qualifying Ownership Interest, and did not have a Board Representative currently serving on the board of directors of EVBS and the board of directors of EVB, EVBS was required to, subject to applicable law, invite a person designated by Fund IV and reasonably acceptable to EVBS to attend meetings of the board of directors of EVBS and the board of directors of EVB in a nonvoting observer capacity (a “Board Observer”).

Following the Merger, Fund IV intends to designate J. Mikesell Thomas to serve as a Board Observer at meetings of the board of directors of SONA and the board of directors of SONA’s banking subsidiary.

Preemptive Rights. Pursuant to the 2013 EVBS SPA, Fund IV was granted preemptive rights in certain circumstances, subject to customary exceptions, providing Fund IV with the opportunity to acquire from EVBS, for the same price and on the same terms as such securities are proposed to be offered to others, such number of securities required to enable Fund IV to maintain its proportionate ownership interest in EVBS Common Stock upon the issuance by EVBS of new securities.

Passivity Commitments. In connection with the Merger Agreement, Fund IV made certain customary passivity commitments to the Federal Reserve to ensure that Fund IV and its affiliates will not, among other things, exercise or attempt to exercise a controlling influence over the management or policies of the Company or any of its subsidiaries.

Registered Securities. The securities issuable to Fund IV in accordance with the Merger Agreement have been registered under the Securities Act of 1933 pursuant to the registration statement on Form S-4 filed with the U.S. Securities and Exchange Commission on April 5, 2017, as amended by Amendment No. 1 to Form S-4 filed on May 8, 2017 and as further amended by Amendment No. 2 to Form S-4 filed on May 10, 2017, and declared effective on May 11, 2017.
