	 	Re:	Corporate Governance Agreement 

 Gentlemen: 

This Corporate Governance Agreement (the “Agreement”) will confirm the agreement among Atlantic Capital Bancshares, Inc., a Georgia
corporation (the “Company”), and Atlantic Capital Bank, a Georgia-chartered commercial bank (the “Bank”), on the one hand, and BCP Fund I Southeast Holdings LLC, a Delaware limited liability company (“Investor”), on the
other hand. In this Agreement, the boards of directors of the Company and the Bank (and any successor thereto as a result of the consummation of the transactions contemplated by the Merger Agreement (as such term is hereinafter defined)) are
sometimes referred to individually as a “Board” and collectively as the “Boards.” 
 Concurrently with entry into this
Agreement, the Company is entering into an Agreement and Plan of Merger of even date herewith (the “Merger Agreement”) between the Company and First Security Group, Inc., a Tennessee corporation (“First Security”). Pursuant to
the terms of the Merger Agreement, First Security will merge with and into the Company (the “Merger”), with the Company being the survivor thereof. Immediately thereafter, the Bank will merge (the “Bank Merger”) with and into
First Security’s wholly owned subsidiary, FSGBank, N.A., a national banking association (“FSGBank”), with FSGBank being the survivor thereof (the “Surviving Bank”). The Company, as the parent holding company for the
Surviving Bank, will take all necessary steps to enforce the obligations set forth herein of the Bank with respect to the Surviving Bank. In connection with the Merger and the Bank Merger, the Boards will be reorganized as provided in the Merger
Agreement. 
 As a condition to the consummation of the Merger, FSGI has required that certain stockholders of the Company, including the
Investor, enter into Support Agreements with FSGI, pursuant to which, subject to the terms and limitations set forth therein, such stockholders will be required to, among other things, vote their shares of stock in the Company in favor of the Merger
at any meeting of the stockholders of the Company held for that purpose. As a material inducement to the Investor to enter into and deliver a Support Agreement to FSGI, the Company has agreed to give the Investor certain rights as set forth herein.









	1.	Board Seats for Investor Nominees 

 (a) The Company and the Bank each agree to:

 (i) immediately upon Investor’s request upon or subsequent to the consummation of the Merger and the Bank Merger, to appoint one
(1) person nominated by Investor (the “Investor Nominee”) as provided in this Section 1 to serve as a director on its Board, subject to any required regulatory approvals and to the reasonable approval of the Company’s
Nominating Committee (the “Nominating Committee”) and the Bank’s Nominating Committee, as applicable, which approval shall not be unreasonably withheld, conditioned or delayed; and 

(ii) at each meeting of stockholders for election of directors at which the position to be occupied under this Agreement by the Investor
Nominee on any Board is to be determined by stockholder election, (A) cause the Investor Nominee to be recommended by the Nominating Committee for consideration by the Board and to be nominated by the Board for election as a director, subject
to the considerations described in clause (i); (B) recommend to its stockholders the election of the Investor Nominee, and use its reasonable best efforts to cause the election of the Investor Nominee to the Board, including soliciting proxies
for the election of the Investor Nominee to the same extent as it does, consistent with past practice, for any other Board nominee for election as a director; and (C) request each then-current member of such Board to vote as a stockholder for
approval of the Investor Nominee. 
 (b) Should for any reason a Board fail to nominate the Investor Nominee, without limiting any other
rights or remedies of Investor, the right of Investor to nominate an Investor Nominee shall remain in effect and Investor shall have the right to repropose one or more Investor Nominees to which this Agreement shall then apply. 

(c) In the event of the death, disability, resignation or removal of the Investor Nominee, the Company and the Bank shall cause the prompt
election to the Boards of a replacement director designated by Investor, subject to the requirements set forth in this Section 1, to fill the resulting vacancy, and such individual shall then be deemed the Investor Nominee for all purposes
under this Agreement. 
 (d) Any Investor Nominee shall be entitled to the same compensation and participation in Company and Bank
equity plans and the same indemnification as the other members of the Boards in connection with his or her role as a director, and each Investor Nominee shall be entitled to reimbursement for documented, reasonable out-of-pocket expenses incurred in
attending meetings of the Boards or any committees thereof. With respect to the indemnification of any Investor Nominee, the Company and the Bank, respectively, agree (i) that it is the indemnitor of first resort (i.e., its obligations
to any Investor Nominee are primary and any obligation of Investor or its Affiliates (other than, for the avoidance of doubt, the Company or the Bank) to advance expenses or to provide indemnification for the same expenses or liabilities incurred by
such person are secondary) with respect to any actions, costs (including reasonable attorneys’ fees), charges, losses, damages, expenses or other liabilities incurred or sustained arising in connection with or related to the execution by such
person of his or her duties as a director of the Company or the Bank, as the case may be, and (ii) that it irrevocably waives, relinquishes and releases Investor and its Affiliates from any and all claims for contribution, subrogation or any
other recovery of any kind in respect thereof.  

  
 2 








 (e) The Company or the Bank, as the case may be, shall notify each Investor Nominee of all
regular and special meetings of the Boards and shall notify each Investor Nominee of all regular and special meetings of any committee of the Boards of which the Investor Nominee is a member in accordance with the Company’s or the Bank’s
bylaws as then in effect. 
 (f) The Company or the Bank, as the case may be, shall provide each Investor Nominee with copies of all
notices, minutes, consents and other materials provided to the other members of the Boards or any committee thereof concurrently with the distribution of such materials to the other members. 

(g) Investor’s rights under this Section 1 shall terminate at such time as Investor (together with its Affiliates) ceases
(i) to Beneficially Own at least 25% of the shares of the common stock of the Company (as adjusted appropriately from time to time for any reorganization, recapitalization, stock dividend, stock split, reverse stock split or other like changes
in the Company’s capitalization), held by Investor or any of its Affiliates immediately following the consummation of the Merger (including any shares underlying any warrant to purchase common stock issued to Investor or its Affiliates), and
(ii) to be deemed by the Federal Reserve Board (or any Federal Reserve Bank) to be a bank holding company with respect to any bank of which the Company is a bank holding company (the “Termination Event”). Following the occurrence of
the Termination Event, upon the written request of the Boards, Investor shall use its reasonable best efforts to cause the Investor Nominee to resign from the Boards within thirty (30) calendar days thereafter. Investor shall inform the Company
if and when a Termination Event occurs. Notwithstanding the foregoing, any Investor Nominee then serving as a director shall continue to be entitled to the compensation, indemnification and expense reimbursement in connection with his or her service
as a director described in Section 1(d), and upon such Investor Nominee’s resignation or failure to stand for re-election, such Investor Nominee shall be entitled to the most favorable indemnification and expense reimbursement as other
former directors of the Boards. 
  

	2.	Board Observer 

 Upon the written request of Investor and in lieu of
Investor’s nomination of an Investor Nominee to serve on a Board, Investor will be entitled to designate a representative (the “Observer”) to receive a standing invitation to attend each of the meetings of such Board, and the
committees thereof, in the capacity of a nonvoting observer. The Observer shall be reasonably acceptable to the applicable Board. The appointment by Investor of an Observer shall not prevent Investor from nominating an Investor Nominee in lieu of
such Observer at a future time. The Observer shall agree to hold in confidence and trust and to act in a fiduciary manner with respect to all information provided to such person in his or her capacity as an Observer. The Company reserves the right
to withhold any information and to exclude the Observer from any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel or
result in disclosure of trade secrets or a conflict of interest. 

  
 3 








 Notwithstanding anything to the contrary contained herein, for the period between the date hereof
until the consummation of the Merger and the Bank Merger, Investor will be allowed to designate one representative to serve as an Observer during such period. Upon consummation of the Merger and the Bank Merger, the Observer will continue in such
capacity only to the extent that no Investor Nominee has been appointed to the Boards. 
 Consistent with Section 1(d), the Observer
shall be entitled to reimbursement for documented, reasonable out-of-pocket expenses incurred in attending meetings of the Boards or any committees thereof. 
  

	3.	Information Rights 

 Commencing as of the date of this Agreement, the Company and
the Bank will provide to Investor all information distributed to the members of either of the Boards or their respective committees, quarterly and annual audited and unaudited consolidated financial statements and copies of all reports required to
be filed under applicable law or under the terms of any outstanding debt instrument. Investor, after appropriate notification of management, may visit and inspect the Company’s and the Bank’s (and their respective subsidiaries’)
properties, books and records during normal business hours and at reasonable frequency. In addition, Investor may consult with management of the Company and the Bank and their respective subsidiaries on Investor’s views on matters relating to
the operation of the business thereof. The foregoing language shall not be deemed to limit any rights or fiduciary obligations of any Investor Nominee in his capacity as a member of the Boards. 

 

	4.	General Provisions 

 (a) Corporate Opportunities. Each of the
parties hereto acknowledges that Investor and its Affiliates and their related investment funds may review the business plans and related proprietary information of any enterprise, including enterprises that may have products or services which
compete directly or indirectly with those of the Company and its subsidiaries, and may trade in the securities of such enterprise. Investor, its Affiliates and their related investment funds shall not be precluded or in any way restricted from
investing or participating in any particular enterprise, or trading in the securities thereof, whether or not such enterprise has products or services that compete with those of the Company or any of its subsidiaries. Without limiting the generality
of the foregoing sentence, except as set forth below, the parties expressly acknowledge and agree that: (a) Investor and its Affiliates have the right to, and shall have no duty (contractual or otherwise) not to, directly or indirectly, engage
in the same or similar business activities or lines of business as the Company and its subsidiaries; and (b) in the event that Investor or any of its Affiliates acquires knowledge of a potential transaction or matter that may be a corporate
opportunity for the Company or any of its subsidiaries, Investor or its Affiliates shall have no duty (contractual or otherwise) to communicate or present such corporate opportunity to the Company or any of its subsidiaries, and, notwithstanding any
provision of this Agreement to the contrary, shall not be liable to the Company or any of its subsidiaries or any other stockholders of the Company for breach of any duty (contractual or otherwise) by reason of the fact that Investor, any of its
Affiliates or any of their related investment funds, directly or indirectly, pursues or acquires such opportunity for itself, directs such opportunity to another Person or does not present such opportunity to the Company or its subsidiaries. If an
Investor 

  
 4 








 
Nominee or an Observer initially acquires knowledge of a potential transaction or matter that is a corporate opportunity for the Company or any of its subsidiaries, such opportunity shall
belong to the Company or the applicable subsidiary, unless such corporate opportunity is offered to such Investor Nominee or Observer solely in his or her capacity as a representative of Investor or any of its Affiliates, in which case such
corporate opportunity shall belong to Investor or such Affiliate, as the case may be.  
 (b) Costs and Expenses. The Company
shall pay any and all reasonable fees and expenses, including reasonable attorneys’ fees, incurred by Investor in connection with any activity or action taken by Investor at the request of the Company or the Bank relating to the Merger or the
Bank Merger, including all requests to make, or assist the Company or the Bank in making, regulatory filings with any Person. 
 (c)
Assignment; Successor. The rights of Investor under this Agreement shall be personal to Investor and the transfer, assignment and/or conveyance of said rights from Investor to any other Person (other than in connection with a transfer of
securities to an Affiliate which assumes the obligations of Investor hereunder) is prohibited and shall be void and of no force or effect. This Agreement shall be binding upon the Surviving Bank, as the successor of the Bank pursuant to the Bank
Merger upon consummation of the transactions contemplated by the Purchase Agreement and the Merger Agreement, and any successor to the Company. 

(d) Equitable Performance. The Company and the Bank agree that Investor will not have an adequate remedy at law for a breach by the
Company or the Bank of this Agreement, and upon any such breach Investor shall be entitled to enforce this Agreement by injunction or with other equitable remedies. 

(e) Rights Non-Exclusive. The rights granted to Investor hereunder are not in substitution for, and shall not be deemed to be in
limitation of, any rights otherwise available to Investor as a holder of securities of the Company or pursuant to any other agreement with the Company or the Bank. 

(f) Governing Law. This Agreement and all transactions contemplated by this Agreement shall be governed by, and construed and enforced
in accordance with, the internal laws of the State of Georgia without regard to principles of conflicts of laws. 
 (g) Jurisdiction and
Venue. Any legal proceeding arising out of or relating to this Agreement shall be brought in the state or federal courts of the State of Georgia. Each party consents to the jurisdiction of such courts in any such legal proceeding and waives any
objection to the laying of venue of any such legal proceeding in such courts. Service of any court paper may be effected on such party by mail, as provided in this Agreement, or in such other manner as may be provided under applicable laws, rules of
procedure or local rules. 
 (h) Waiver of Jury Trial. TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT CANNOT BE WAIVED, EACH
PARTY HEREBY WAIVES AND COVENANTS THAT IT WILL NOT ASSERT (WHETHER AS PLAINTIFF, DEFENDANT, OR OTHERWISE) ANY RIGHT TO TRIAL BY JURY IN ANY FORUM IN RESPECT OF ANY ISSUE OR ACTION, CLAIM, CAUSE OF ACTION, OR SUIT (WHETHER IN


  
 5

INCIDENTAL TO THE TRANSACTIONS CONTEMPLATED HEREBY, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING. EACH PARTY ACKNOWLEDGES THAT IT HAS BEEN INFORMED BY THE OTHER PARTIES THAT THIS SECTION CONSTITUTES A MATERIAL INDUCEMENT UPON WHICH IT
IS RELYING, AND WILL RELY IN ENTERING INTO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF EACH SUCH PARTY TO
THE WAIVER OF ITS RIGHT TO TRIAL BY JURY. 
 (i) Entire Agreement. Except as otherwise expressly set forth herein, this Agreement,
together with the other documents and instruments referred to herein, embody the complete agreement and understanding among the parties hereto with respect to the subject matter hereof, and supersede and preempt any prior understandings, agreements,
or representations by or among the parties, written or oral, that may have related to the subject matter hereof in any way. 
 (j)
