The Michigan Business Corporation Act also gives Mercantile broad powers to indemnify defined persons against expenses and reasonable settlement payments in connection with any action by or in the right of Mercantile, provided the person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to Mercantile's best interests, except that no indemnification may be made if that person is adjudged to be liable to Mercantile unless and only to the extent the court in which that action was brought determines upon application that, despite the adjudication, but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for reasonable expenses as the court deems proper. In addition, to the extent that any specified person is successful in the defense of any defined legal proceeding, Mercantile is required by the Michigan Business Corporation Act to indemnify him or her against expenses, including attorneys' fees that are actually and reasonably incurred in connection with the proceeding.</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 27pt;">Mercantile's Bylaws contain indemnification provisions concerning third party actions as well as actions in the right of Mercantile. The Bylaws provide that Mercantile shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of Mercantile) by reason of the fact that he or she is or was a director or officer of Mercantile or while serving as such a director or officer, is or was serving at the request of Mercantile as a director, officer, partner, trustee, employee or agent of another foreign or domestic corporation, partnership, joint venture, trust or other enterprise, whether for profit or not, against expenses (including attorney's fees), judgments, penalties, fees and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of Mercantile or its shareholders and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 27pt;">Federal Deposit Insurance Corporation regulations impose limitations on indemnification payments which could restrict, in certain circumstances, payments by Mercantile or its bank subsidiaries to their respective directors or officers otherwise permitted under the Michigan Business Corporation Act or the Michigan Banking Code.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 27pt;">With respect to derivative actions, the Bylaws provide that Mercantile shall indemnify any person who was or is a party to or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of Mercantile to procure a judgment in its favor by reason of the fact that he or she is or was a director or officer of Mercantile, or while serving as such a director or officer, is or was serving at the request of Mercantile as a director, officer, partner, trustee, employee or agent of another foreign or domestic corporation, partnership, joint venture, trust or other enterprise, whether for profit or not, against expenses (including attorney's fees) and amounts paid in settlement actually and reasonably incurred by him or her in connection with the action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of Mercantile or its shareholders. No indemnification is provided in the Bylaws in respect of any claim, issue or matter in which such person has been found liable to Mercantile except to the extent that a court of competent jurisdiction determines upon application that, despite the adjudication of liability but in view of all circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 27pt;">Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of Mercantile pursuant to the provisions discussed above or otherwise, Mercantile has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 27pt;">The Michigan Business Corporation Act permits Mercantile to purchase insurance on behalf of its directors and officers against liability arising out of their positions with Mercantile (or positions held with another entity at the request of Mercantile), whether or not the liabilities would be within the indemnification provisions described above.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 27pt;">Mercantile&#8217;s Articles of Incorporation and Bylaws provides that Mercantile may purchase and maintain insurance to protect itself and any such director, officer, or other person against any liability arising out of such service to Mercantile, whether or not Mercantile has the power to indemnify such person.</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 27pt;">Under an insurance policy maintained by Mercantile, its directors and officers are insured within the limits and subject to the limitations of the policy, against specified expenses in connection with the defense of specified claims, actions, suits or proceedings, and specified liabilities which might be imposed as a result of claims, actions, suits or proceedings, which may be brought against them by reason of being or having been directors and officers of Mercantile.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 27pt;">Section 209(1)(c) of the Michigan Business Corporation Act permits corporations to limit the personal liability of their directors in certain circumstances. However, under the Michigan Business Corporation Act, a corporation may not eliminate or limit a director's liability to the corporation or its shareholders for money damages for any action taken or any failure to take any action as a director for any of the following: (1) the amount of a financial benefit received by a director to which he or she is not entitled; (2) intentional infliction of harm on the corporation or its shareholders; (3) a violation of Section 551 of the Michigan Business Corporation Act; and (4) an intentional criminal act.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 27pt;">Mercantile's Articles of Incorporation provide that its directors shall not be personally liable to it or its shareholders for monetary damages for breach of fiduciary duty, except for liability (1) for any breach of the director's duty of loyalty to Mercantile or its shareholders; (2) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law; (3) for a violation of Section 551(1) of the Michigan Business Corporation Act; or (4) for any transaction from which the director derived any improper personal benefit. Under the Michigan Business Corporation Act, if prior to October 24, 1997 the articles of incorporation of a corporation contained a provision which, subject to exceptions, eliminated liability of a director as Mercantile's does, that provision is considered to eliminate liability of a director to the extent permitted in Section 209(1)(c) of the Michigan Business Corporation Act.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt; text-indent: 27pt;">Pursuant to Mercantile's Articles of Incorporation, if the Michigan Business Corporation Act is amended after the date of the Articles of Incorporation to authorize corporate action eliminating or limiting the personal liability of directors, then the liability of a director of Mercantile shall be eliminated or limited to the fullest extent permitted by the Michigan Business Corporation Act, as so amended.</p>

In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.</p>

Item 6.
Indemnification of Directors and Officers.
Indemnification
Sections 561-571 of the Michigan Business Corporation Act, as amended, grant Mercantile broad powers to indemnify any person in connection with legal proceedings brought against that person by reason of their present or past status as an officer or director of Mercantile, provided that the person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to Mercantile's best interests, and with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful. The Michigan Business Corporation Act also gives Mercantile broad powers to indemnify defined persons against expenses and reasonable settlement payments in connection with any action by or in the right of Mercantile, provided the person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to Mercantile's best interests, except that no indemnification may be made if that person is adjudged to be liable to Mercantile unless and only to the extent the court in which that action was brought determines upon application that, despite the adjudication, but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for reasonable expenses as the court deems proper. In addition, to the extent that any specified person is successful in the defense of any defined legal proceeding, Mercantile is required by the Michigan Business Corporation Act to indemnify him or her against expenses, including attorneys' fees that are actually and reasonably incurred in connection with the proceeding.
Mercantile's Articles of Incorporation provide that it shall indemnify its present and past directors, officers, and such other persons as the Board of Directors may authorize to the full extent permitted by law.
2
Mercantile's Bylaws contain indemnification provisions concerning third party actions as well as actions in the right of Mercantile. The Bylaws provide that Mercantile shall indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of Mercantile) by reason of the fact that he or she is or was a director or officer of Mercantile or while serving as such a director or officer, is or was serving at the request of Mercantile as a director, officer, partner, trustee, employee or agent of another foreign or domestic corporation, partnership, joint venture, trust or other enterprise, whether for profit or not, against expenses (including attorney's fees), judgments, penalties, fees and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action, suit or proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of Mercantile or its shareholders and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.
Federal Deposit Insurance Corporation regulations impose limitations on indemnification payments which could restrict, in certain circumstances, payments by Mercantile or its bank subsidiaries to their respective directors or officers otherwise permitted under the Michigan Business Corporation Act or the Michigan Banking Code.
With respect to derivative actions, the Bylaws provide that Mercantile shall indemnify any person who was or is a party to or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of Mercantile to procure a judgment in its favor by reason of the fact that he or she is or was a director or officer of Mercantile, or while serving as such a director or officer, is or was serving at the request of Mercantile as a director, officer, partner, trustee, employee or agent of another foreign or domestic corporation, partnership, joint venture, trust or other enterprise, whether for profit or not, against expenses (including attorney's fees) and amounts paid in settlement actually and reasonably incurred by him or her in connection with the action or suit if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of Mercantile or its shareholders. No indemnification is provided in the Bylaws in respect of any claim, issue or matter in which such person has been found liable to Mercantile except to the extent that a court of competent jurisdiction determines upon application that, despite the adjudication of liability but in view of all circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court shall deem proper.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of Mercantile pursuant to the provisions discussed above or otherwise, Mercantile has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.
Insurance
The Michigan Business Corporation Act permits Mercantile to purchase insurance on behalf of its directors and officers against liability arising out of their positions with Mercantile (or positions held with another entity at the request of Mercantile), whether or not the liabilities would be within the indemnification provisions described above.
Mercantile's Articles of Incorporation and Bylaws provides that Mercantile may purchase and maintain insurance to protect itself and any such director, officer, or other person against any liability arising out of such service to Mercantile, whether or not Mercantile has the power to indemnify such person.
3
Under an insurance policy maintained by Mercantile, its directors and officers are insured within the limits and subject to the limitations of the policy, against specified expenses in connection with the defense of specified claims, actions, suits or proceedings, and specified liabilities which might be imposed as a result of claims, actions, suits or proceedings, which may be brought against them by reason of being or having been directors and officers of Mercantile.
Limitation of Director Liability
Section 209(1)(c) of the Michigan Business Corporation Act permits corporations to limit the personal liability of their directors in certain circumstances. However, under the Michigan Business Corporation Act, a corporation may not eliminate or limit a director's liability to the corporation or its shareholders for money damages for any action taken or any failure to take any action as a director for any of the following: (1) the amount of a financial benefit received by a director to which he or she is not entitled; (2) intentional infliction of harm on the corporation or its shareholders; (3) a violation of Section 551 of the Michigan Business Corporation Act; and (4) an intentional criminal act.
Mercantile's Articles of Incorporation provide that its directors shall not be personally liable to it or its shareholders for monetary damages for breach of fiduciary duty, except for liability (1) for any breach of the director's duty of loyalty to Mercantile or its shareholders; (2) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law; (3) for a violation of Section 551(1) of the Michigan Business Corporation Act; or (4) for any transaction from which the director derived any improper personal benefit. Under the Michigan Business Corporation Act, if prior to October 24, 1997 the articles of incorporation of a corporation contained a provision which, subject to exceptions, eliminated liability of a director as Mercantile's does, that provision is considered to eliminate liability of a director to the extent permitted in Section 209(1)(c) of the Michigan Business Corporation Act.
Pursuant to Mercantile's Articles of Incorporation, if the Michigan Business Corporation Act is amended after the date of the Articles of Incorporation to authorize corporate action eliminating or limiting the personal liability of directors, then the liability of a director of Mercantile shall be eliminated or limited to the fullest extent permitted by the Michigan Business Corporation Act, as so amended.

Item 9.
Undertakings.
(a)
The undersigned registrant hereby undertakes:
(1)
To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)
To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;
(ii)
To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) (§ 230.424(b) of this chapter) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement.
(iii)
To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
provided, however
, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 (15 U.S.C. 78m or 78o(d)) that are incorporated by reference in the registration statement.
(2)
That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
5
(3)
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
(b)
The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(h)
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
