LASHLEY (collectively, the “PL Capital Parties”) on behalf of themselves and
their affiliates, on the other hand. BFIN and the PL Capital Parties together,
collectively, shall be referred to in this Agreement as the “Parties”. In
consideration of the covenants, promises and undertakings set forth herein, and
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the Parties hereby agree as follows:
1.Board Membership.
Upon the execution of this Agreement, the Board of Directors of BFIN agrees (1)
to nominate John W. Palmer to serve as a director of BFIN in the class of
directors with terms expiring at BFIN’s 2020 Annual Meeting of stockholders or
until their successors are elected and qualified and (2) to include Mr. Palmer
as a nominee of the Board of Directors of BFIN on the slate of nominees
recommended by the Board of Directors of BFIN in BFIN’s proxy statement and
proxy card relating to the 2017 Annual Meeting of Stockholders. In addition and
as a condition to Mr. Palmer’s nomination for election as a director of BFIN,
Mr. Palmer and the PL Capital Parties agree to provide to BFIN in a timely
manner information required to be, or customarily disclosed for, BFIN’s
directors, candidates for directors, and their affiliates and representatives in
a proxy statement or other filings under applicable law, rules, regulations or
listing standards, information in connection with assessing eligibility,
independence and other criteria applicable to directors or satisfying compliance
and legal obligations, and such other information as reasonably requested by the
Company from time to time. At all times from and after the date of this
Agreement, BFIN’s Board of Directors will also appoint, at its discretion, all
other persons to fill any remaining director positions or vacancies on the BFIN
Board of Directors and Board committee positions; provided, that BFIN’s Board of
Directors acknowledges and agrees as follows: (i) it will consider, in good
faith, the appointment of Mr. Palmer to committees of the BFIN Board of
Directors; (ii) it will meet with Mr. Palmer following the filing of the BFIN’s
annual report on Form 10-K to discuss his goals and objectives as a director of
BFIN and otherwise to facilitate Mr. Palmer’s transition to service on the BFIN
Board of Directors; (iii) it will cause the Bank to continue to provide Mr.
Palmer electronic access to each “Meeting Book” and the related meeting
materials that are published to the Bank’s “NASDAQ Director’s Desk” site in
connection with meetings of the board of directors of the Bank held after such
election, provided that Mr. Palmer shall not be provided access to information
that would cause BFIN or the Bank to violate applicable laws or regulations; and
(iv) it will cause BFIN to provide Mr. Palmer the normal compensation paid to
similarly situated persons who serve as directors of BFIN only.
2.Standstill.
(i)The PL Capital Parties each acknowledge and represent that the investment in
BFIN is not intended to constitute a “controlling” investment for federal
banking law purposes and, accordingly, agree that during the Standstill Period
(as defined below), the PL Capital Parties and their affiliates or associates
(as defined in Rule 12b-2 promulgated pursuant to the Securities Exchange Act of
1934, as amended (the “Exchange Act”)) will not (and they will not assist or
encourage others to), directly or indirectly, in any manner, without prior
written approval of the Board of Directors of BFIN:
(1)acquire, offer or propose to acquire, solicit an offer to sell or agree to
acquire directly or indirectly, alone or in concert with others, by purchase,
tender, exchange, gift, through the acquisition of control of another person, by
joining a partnership, limited partnership or syndicate or other “group” (within
the meaning of such term in Section 13(d) of the Exchange Act) or otherwise, any
direct or indirect beneficial ownership (within the meaning of Rule 13d-3 under
the Exchange Act) or any direct or indirect interest in any securities or direct
or indirect rights, warrants or options to acquire, or securities convertible
into or exchangeable for (collectively, an “Acquisition”), any securities of
BFIN, such that as a result of such of such Acquisition, the PL Capital Parties
would maintain beneficial ownership in excess of 9.99% of the outstanding shares
of BFIN common stock;
(2)make, engage in, or in any way participate in, directly or indirectly, alone
or in concert with others, any “solicitation” of “proxies” or consents to vote
(as such terms are used in the proxy rules of the

Exchange Act) or seek to advise, encourage, or influence in any manner
whatsoever any person with respect to the voting of any securities of BFIN;
(3)form, join, encourage, influence, advise or in any way participate in a
“group” within the meaning of Section 13(d)(3) of the Exchange Act (other than a
group involving solely the PL Capital Parties) with respect to any securities of
BFIN (for the benefit of clarification and the avoidance of doubt, this
provision shall not prohibit changes in the membership of the group involving
the PL Capital Parties as long as any additional member(s) acknowledges and
agrees to be bound by the terms of this Agreement) or otherwise in any manner
agree, attempt, seek or propose to deposit any securities of BFIN in any voting
trust or similar arrangement, or subject any securities of BFIN to any
arrangement or agreement with respect to the voting thereof, except as expressly
set forth in this Agreement;

entity not a (a) party to this Agreement, (b) member of the BFIN Board of
Directors, (c) officer of BFIN or (d) a PL Capital Party affiliate (a “Third
Party”) that would knowingly result in such Third Party, together with its
affiliates and associates, owning, controlling or otherwise having any
beneficial or other ownership interest in the aggregate of more than 4.9% of the
shares of BFIN common stock outstanding at such time, except in a transaction
approved by the Board or in ordinary course public capital markets sale
transactions;
(7)otherwise act, alone or in concert with others, to seek to offer to BFIN or
any of its stockholders any business combination, restructuring,

or in concert with others, to control or change the management, Board of
Directors or policies of BFIN or the Bank or nominate any person as a director
of BFIN who is not nominated by the then incumbent directors (provided that if
there is a vacancy on the BFIN Board of Directors the PL Capital Parties may
submit suggestions on a confidential basis to the BFIN Board of Directors or the
Corporate Governance and Nominating Committee of the BFIN Board of Directors for
nominees to the Board of Directors pursuant to the nomination policy adopted by

to Section 12(g)(4) of the Exchange Act;
(10)make any statement or announcement that constitutes an ad hominem attack on,
or otherwise disparages or causes to be disparaged (a) any of the proposals
described in this Agreement or (b) BFIN or affiliates thereof, and any of its
current or former officers or directors;
(11)enter into any discussions, negotiations, agreements or understandings with
any Third Party with respect to any of the foregoing, or advise, assist,
