STANDSTILL AGREEMENT

This STANDSTILL AGREEMENT is entered into on May 16, 2016 by and between Middlefield Banc Corp., an Ohio corporation (“Middlefield”), and Northwest Bancshares, Inc., a Maryland corporation (“Northwest”).

WHEREAS, Northwest is purchasing from Middlefield shares of Middlefield common stock,

WHEREAS, the purchase price for the shares is $33 per share,

WHEREAS, at completion of the purchase Northwest will not own more than 4.99% of the issued and outstanding shares of Middlefield voting stock, and

WHEREAS, it is a condition to Middlefield’s willingness to complete the transaction that Northwest enter into an agreement to refrain from acquiring ownership of more than 4.99% of Middlefield’s common stock and to refrain from taking specified other actions.

NOW, THEREFORE, in consideration of these premises, the representations, warranties, and covenants contained in this Standstill Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Middlefield and Northwest hereby agree as follows.

Section 1. Definitions. For purposes of any obligations imposed by this Standstill Agreement, the term Middlefield includes any person or entity that controls, is controlled by, or is under common control with Middlefield, and the term Northwest includes any person or entity that controls, is controlled by, or is under common control with Northwest.

Section 2. Standstill Provisions. (a) Except as expressly permitted in this Standstill Agreement, Northwest will not take any of the following actions and will not assist or encourage others to take any of the following actions, whether by providing financing or otherwise, and whether alone or in concert with others or as a part of a group (as the term “group” is defined under section 13(d)(3) of the Securities Exchange Act of 1934) –

1) seek to have a representative on the Middlefield board of directors, seek removal of any member of Middlefield’s board of directors, seek to have a representative on the board of directors of The Middlefield Banking Company, or seek removal of any member of the board of directors of The Middlefield Banking Company, or

2) propose, effect, or seek to participate in a merger or other business combination involving Middlefield or any of its subsidiaries, or

3) unless initiated by Middlefield, acquire record or beneficial ownership of more than 4.99% of Middlefield’s voting securities (and for this purpose the right to acquire ownership of Middlefield voting securities, whether through options, warrants, convertible securities, or otherwise, and regardless of whether exercisable, is considered the equivalent of actual ownership of Middlefield voting securities), or

3) seek to take any of the actions regarding Middlefield or regarding Middlefield common stock for which prior approval of the Federal Reserve Board or its staff is necessary, or

4) enter into discussions, negotiations, agreements, arrangements, or understandings with a third party for any of the foregoing, or make or disclose a proposal to amend or terminate any of the provisions of this section 2, or

(b) Without Middlefield’s prior written consent, Northwest will not, directly or indirectly, sell, transfer, or otherwise dispose of any interest in the shares acquired hereunder to any person that Northwest believes, after reasonable inquiry, would be beneficial owner after any such sale or transfer of more than 5% of the outstanding shares of Middlefield’s common stock.

(c) Northwest will be present, in person or by proxy, at any meeting of shareholders of Middlefield so that the common shares held by Northwest may be counted for the purpose of determining the existence of a quorum at such meeting.

(d) The provisions of sections 2(a), 2(b), and 2(c) of this Standstill Agreement terminate when Northwest no longer owns Middlefield common stock.

Section 6. Governing Law. This Standstill Agreement is governed and will be construed in accordance with the laws of the State of Ohio, without giving effect to applicable principles of conflict of laws.

Section 7. Severability. If any term or other provision of this Standstill Agreement is invalid, illegal, or incapable of being enforced by any law or public policy, all other terms and provisions of this Standstill Agreement nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby are not affected in any manner materially adverse to any party. Upon a determination that any term or other provision is invalid, illegal, or incapable of being enforced, the parties hereto will negotiate in good faith to modify this Standstill Agreement in order to carry out the original intent of the parties as closely as possible.

Section 8. Assignment; Amendments. (a) Neither this Standstill Agreement nor any of the rights, interests, or obligations hereunder may be assigned by Middlefield or by Northwest in whole or in part (whether by operation of law or otherwise) without advance written consent of the other party, and any attempt to make any such assignment without consent is null and void. Subject to the preceding sentence, this Standstill Agreement is binding upon, inures to the benefit of, and is enforceable by the parties and their respective successors and permitted assigns.

(b) No amendment or waiver of this Standstill Agreement is effective unless it is in writing and is signed by Middlefield and by Northwest.

Section 9. Enforcement. (a) Each of Middlefield and Northwest acknowledges that the other party will not have an adequate remedy at law for money damages if any of the covenants or agreements are not performed in accordance with the terms of this Standstill Agreement, and it is therefore agreed that each of Middlefield and Northwest, in addition to and without limiting any other remedy or right it may have, has the right to an injunction or other equitable relief in any court of competent jurisdiction, enjoining any actual or potential breach and enforcing specifically the terms and provisions hereof, and each of Middlefield and Northwest hereby waives (x) any and all defenses that it may have on the ground of lack of jurisdiction or competence of the court to grant an injunction or other equitable relief and (y) the need to post any bond that may be required for the granting of an injunction or other equitable relief.

(b) All rights, powers and remedies provided under this Standstill Agreement or otherwise available at law or in equity are cumulative and not alternative, and the exercise or beginning of the exercise of any thereof by any party does not preclude the simultaneous or later exercise of any other right, power, or remedy.

(c) In the event of litigation relating to this Standstill Agreement, if a court of competent jurisdiction determines that Northwest or its representatives have breached this Standstill Agreement, then Northwest shall be liable and pay to Middlefield the reasonable legal fees and costs incurred by Middlefield in connection with such litigation, including any appeal therefrom, as a court of competent jurisdiction may deem appropriate under the circumstances.
