PRELIMINARY PROSPECTUS

SUBJECT TO COMPLETION, DATED MAY 3, 2011

          We are distributing to our shareholders, free of charge, non-transferable subscription rights to purchase shares of our common stock. This is called the "rights offering." You will receive one right to purchase one share of common stock for each whole share of common stock that you hold of record as of 5:00 p.m., Eastern Time, on May 2, 2011. There is no over-subscription privilege. Shareholders who wish to purchase additional shares in the offering may submit an expression of interest to participate in the public offering. Subscription rights may not be sold, transferred or assigned to anyone else and will not be listed for trading on any stock exchange or trading market. We are offering for sale a total of 17,826,086 shares of common stock in the rights offering. The exercise of subscription rights is irrevocable and may not be cancelled or modified. We are also offering to sell to the public any shares offered but not sold in the rights offering. This is called the "public offering." The public offering and the rights offering are collectively referred to in this prospectus as the "offerings."

          We intend to use a portion of the net proceeds of the offerings to contribute to the capital of the Bank to increase the Bank's capital and regulatory capital ratios and for general corporate purposes, including funding organic loan growth and long-term strategic opportunities. A portion of the net proceeds of the offerings will be retained by the Company to pay its continuing operating expenses while the Company is unable to fund those expenses with dividends from the Bank.

          The purchase price for shares in the rights offering and in the public offering is $2.30 per share. Subscription rights will expire at 5:00 p.m., Eastern Time, on June 7, 2011, and the public offering will terminate at 5:00 p.m., Eastern Time, on June 20, 2011, unless we extend either or both offering periods in our discretion. Neither the rights offering nor the public offering is an underwritten offering. Our shares of common stock are being offered directly by us without the services of an underwriter or selling agent. Our common stock is traded on The Nasdaq Global Select Market under the ticker symbol "MCBC." The last reported sales price of our common stock on The Nasdaq Global Select Market on April 29, 2011 was $2.59 per share. The average of the last reported sale prices during the 30 trading days before May 2, 2011, the date on which our Board of Directors determined the offering price, was $2.70 per share. We intend to list the shares of common stock issued in the offerings on The Nasdaq Global Select Market under the same ticker symbol. We have engaged Registrar and Transfer Company to serve as subscription agent and Eagle Rock Proxy Advisors, LLC to serve as information agent for the rights offering. The subscription agent will hold in escrow the funds we receive from subscribers in the rights offering until we complete or cancel the rights offering.

          Investing in our common stock involves risks. The rights offering does not contain a minimum subscription condition. Shareholders who subscribe may continue to own shares in the Company when it and the Bank do not satisfy all minimum regulatory capital requirements. Failure to meet minimum regulatory capital requirements could result in significant enforcement actions against the Company and the Bank, including a regulatory takeover of the Bank, in which case shareholders would receive little if anything for their investment. See "Risk Factors" beginning on page 23.

          Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense. The shares of common stock are not savings accounts, deposits or other obligations of a bank or savings institution and are not insured by the Federal Deposit Insurance Corporation or any other government agency.

The date of this prospectus is May [•], 2011

          This summary highlights information contained elsewhere in, or incorporated by reference into, this prospectus. As a result, it does not contain all of the information that may be important to you or that you should consider before investing in our common stock. Before making an investment decision, you should read this entire prospectus, including the "Risk Factors" section, and the documents incorporated by reference into this prospectus, which are described below under "Incorporation of Certain Information by Reference" on page 54.

Overview

          Macatawa Bank Corporation is a Michigan corporation and a registered bank holding company. Macatawa's business is concentrated in a single industry segment - commercial banking. Through its wholly-owned subsidiary, Macatawa Bank, Macatawa offers a full range of commercial and personal banking services, including checking, savings and certificates of deposit accounts, cash management, safe deposit boxes, trust services and commercial, mortgage and consumer loans through its twenty-six branch offices and a lending and operation service facility in Ottawa County, Kent County and northern Allegan County, Michigan. Other services we offer include ATMs, internet banking, telephone banking and debit cards. Macatawa Bank provides various brokerage services, including discount brokerage through Infinex, personal financial planning and consultation regarding mutual funds.

          The Bank was formed in 1997 and until 2009 our strategy has been to profitably grow our business based upon our mission to attract clients who prefer to conduct business with a locally managed institution that demonstrates an active interest in their business and personal financial affairs, places high priority on local decision-making and contributes financial and employee support to community initiatives. Beginning in late 2009, our strategic direction and focus has turned from growth to improving our internal operations, including complying with the Consent Order, working out of problem loans and assets and returning the Company to profitable operations.

          At March 31, 2011, we had total assets of $1.56 billion, total loans of $1.15 billion, total deposits of $1.26 billion and shareholders' equity of $69.2 million. During the first quarter of 2011, we recognized net income of $1.3 million, compared to a net loss of $21.1 million in the first quarter of 2010. During the fourth quarter of 2010, we recognized net income of $835,000 compared to a net loss of $9.2 million in the fourth quarter of 2009. During the third quarter of 2010, we recognized net income of $703,000 compared to a net loss of $19.9 million in the third quarter of 2009. During the second quarter of 2010, we recognized net income of $1.7 million compared to a net loss of $30.4 million in the second quarter of 2009. This represents four consecutive quarters of profitability following six consecutive quarters of net losses.

          During 2008 and 2009, Macatawa reported operating losses of $38.9 million and $63.6 million, respectively. The losses for 2008 and 2009 were largely attributable to loan losses, lost interest on nonperforming assets and rising costs of administering problem assets associated with the rapid increase in problem loans and other real estate assets. Losses in 2009 included the establishment of a tax valuation allowance and losses in 2008 included the write-off of goodwill. The loan and problem asset related losses continued in the first quarter of 2010, as the Company reported a net loss of $21.1 million for that quarter.

          In February 2010, Macatawa Bank entered into a Consent Order with the Federal Deposit Insurance Corporation ("FDIC") and the Michigan Office of Financial and Insurance Regulation ("OFIR"), in which the Bank agreed to increase management and board oversight, improve process and controls, limit lending to certain borrowers, obtain regulatory approval of future dividends, and improve regulatory capital ratios. Please see "Consent Order with Macatawa Bank and its Regulators" below for more information regarding the Consent Order. In July 2010, the Company entered into a Written Agreement with the Federal Reserve Bank of Chicago ("FRB"). Among other things, the Written Agreement provides that the Company must take appropriate steps to utilize its financial and managerial resources to serve as a source of strength to Macatawa Bank and the Company may not declare or pay any dividends without the prior written consent of the FRB. Please see "Written Agreement with the Company and its Regulator" below for more information regarding the Written Agreement.

          The Board of Directors of Macatawa has significantly changed the strategic direction and focus of the Bank to improve its internal operations and to work out of its problem loans and assets. During the fourth quarter of 2009, the Macatawa Board of Directors elected a new independent Chairman of the Board. Macatawa has since worked

TABLE OF CONTENTS

          As a result of these efforts, the Company has achieved significantly improved results:

Our Capital Needs

          We need additional capital in order to take advantage of the opportunities that may be presented to us. Management believes that with additional capital, the Company will be able to act upon opportunities to improve its profitability and enhance its franchise and overall shareholder value. While additional capital will give us a tool we believe we can use to build shareholder value, we also need capital to comply with the terms of our regulatory Consent Order, to provide an increased ability to absorb potential future losses and to provide us with the foundation for future growth.

          At March 31, 2011, the Bank's Tier 1 Leverage Capital Ratio was 7.1% and the Total Risk Based Capital Ratio was 10.4%, which would ordinarily qualify the Bank as "well capitalized" under the regulatory capital standards absent the Consent Order. As of March 31, 2011, the Bank needed a capital injection of approximately $14.0 million to comply with the Tier 1 Leverage Capital Ratio requirement and needed a capital injection of approximately $7.1 million to comply with the Total Risk Based Capital Ratio requirement of the Consent Order. The amounts of capital needed may increase in the event of future losses and other events. Because the Bank is subject to the Consent Order, it cannot be categorized as "well capitalized," regardless of actual capital levels.

          At a Special Meeting of Shareholders held on March 25, 2011, our shareholders overwhelmingly approved a proposal to amend the Articles of Incorporation to increase the number of authorized shares of our common stock from 40,000,000 to 200,000,000. Over 84% of the shares voted on the proposal were voted for approval of the proposal. We believe that the results of the voting at the special meeting show that our shareholders support our plans to raise capital. The Company has sufficient authorized and unissued shares of common stock to complete the offerings.

Our Strengths

          Our focus on community banking and strong customer service has historically positioned us well in the markets that we serve and we believe those strengths will help position us for a return to sustained profitability. We have achieved strong pre-tax, pre-provision income through a stable and substantial core funding base, which has resulted in a comparatively strong net interest margin and expansion of core deposits in our markets. For additional information about our pre-tax, pre-provision income, see "Summary of Selected Consolidated Financial Information." Our key strengths include:

Risks We Face

          Investing in our common stock involves risks. See "Risk Factors" beginning on page 23 of this prospectus to read about risks you should carefully consider before buying our common stock.

Our Market Area

          Our primary market area includes Ottawa, Kent and northern Allegan Counties, all located in Western Michigan. This area includes two mid-sized cities, Grand Rapids and Holland, and rural areas. Grand Rapids is the second largest city in Michigan. Holland is the largest city in Ottawa County. Both cities and surrounding areas have a solid and diverse economic base, which includes health and life sciences, tourism, office furniture, automotive components and assemblies, pharmaceutical, transportation, equipment, food and construction supplies. Grand Valley State University, a 24,000-student regional university with nearly 2,000 employees, has its three main campuses in our market area. GVSU and several smaller colleges and university affiliates located in our market area help stabilize the local economy because they are not as sensitive to the fluctuations of the broader economy.

          While Michigan has the fifth highest seasonally adjusted unemployment rate in the United States (as of March 2011), the seasonally-adjusted unemployment rate decreased from 13.3% in March 2010 to 10.3% in March 2011 and the unadjusted employment rate decreased from 14.2% in March 2010 to 11.0% in March 2011. The Michigan March 2011 seasonally-adjusted unemployment rate of 10.3% was the lowest seasonally-adjusted monthly

TABLE OF CONTENTS

          University of Michigan economists project positive job gains of 64,600 during 2011 and 61,500 during 2012. University of Michigan economists also project that after turning positive again in 2010 at a rate of 2.8 percent, personal income growth will increase to 5.1 percent in 2011, returning to the 3 percent range in 2012.

          Of Michigan's 83 counties, Ottawa County had the 11th lowest unadjusted unemployment rate in the state and the 10th lowest unadjusted unemployment rate in Michigan's lower peninsula at 9.3% for March 2011. Ottawa County has maintained a lower monthly unadjusted unemployment rate than the State of Michigan as a whole throughout the last decade and continues to do so. Kent County tied for the 6th lowest unadjusted unemployment rate in both the state and Michigan's lower peninsula at 8.8% for March 2011. Kent County has maintained an equivalent or lower monthly unadjusted unemployment rate than the State of Michigan as a whole since December 2003 and continues to do so.

          It appears that the housing market in our primary market area is beginning to show signs of stabilization. Based on U.S. Census data, housing building permits in the Grand Rapids-Wyoming metropolitan area were up approximately 7.65% in 2010 compared to 2009. In the Holland-Grand Haven metropolitan area, housing building permits were up approximately 9.21% in 2010 compared to 2009.

          The Michigan Economic Activity Index equally weighs nine, seasonally adjusted coincident indicators of real economic activity that reflect activity in the construction, manufacturing and service sectors as well as job growth and consumer outlays. The index is measured on a scale of 110. The index rose one point in January 2011 to a level of 87, which is two points above the average for all of 2010 and 15 points above the index cycle low of 71.

          Kent County had a population of approximately 609,082 for 2010 and is projected to grow by approximately 1.91% from 2010-2015. Kent County had a median household income of approximately $47,684 for 2009, which was the sixteenth highest in the state. Ottawa County had a population of approximately 261,957 for 2009 and is projected to grow by approximately 7.19% from 2009-2020. Ottawa County had a median household income of approximately $52,107 for 2009, which was the ninth highest in the state. The Grand Rapids Combined Statistical Area had a population of approximately 1,331,964 for 2010 and is projected to grow by approximately 1.86% from 2010-2015.

          Following completion of the offerings, we believe we will be well-positioned to take advantage of growth opportunities in our market area. As many of our largest competitors have pulled back or reduced their lending efforts in our market area, we believe opportunities exist to increase our lending market share through organic growth. We continue to invest in our credit and lending teams, through both hiring experienced commercial lenders and additional underwriting and credit monitoring training of our employees.

Our Board of Directors

Strengthening Our Board of Directors and Board Oversight of the Company

          The Board of Directors is committed to fulfilling its responsibility to the shareholders of the Company to oversee the Company's overall performance and the integrity of our financial disclosures. We have made significant efforts to increase and improve Board oversight of the Company and governance of the Bank to build accountability, confidence and performance. We have also implemented changes to promote the independence and objectivity of the Board of Directors. These efforts have included:

TABLE OF CONTENTS

Our Executive Leadership Team

          The members of our leadership team have significant past experience working in senior positions at financial institutions or organizations. Our leadership team is able to leverage that experience to have a broader and sophisticated understanding of the financial services business and the financial markets. Our leadership team has structured our company to emulate certain aspects of larger financial institutions that we perceive to be beneficial to our business and clients without losing our community-based roots. Combined, our leadership team has over 170 years of banking and financial experience.

Our Strategy

          The Board of Directors of the Company has significantly changed the strategic direction and focus of the Bank to improve its internal operations and to work out of its problem loans and assets. During the fourth quarter of 2009, the Board of Directors elected a new, independent Chairman of the Board. The Company has since worked closely with its regulators at the FRB and the Bank's regulators at the FDIC and OFIR to put in place improved controls and procedures. The Board has implemented additional corporate governance practices and disciplined business and banking principles, and implemented more conservative lending principles that comply with regulatory standards, and appointed experienced and disciplined lending and compliance personnel. The focus of our management team has turned from growing our business to executing these disciplined business and banking procedures, limiting future losses, preserving capital and improving operational efficiencies.

          Despite the strain that a continuing soft economy places on the loan portfolio, the Company is committed to its efforts to mitigate future loan losses. Tangible steps have been taken to reduce exposure within certain credit concentrations, establish more conservative lending principles that comply with regulatory standards, implement new lending and compliance policies and procedures, and enhance problem loan identification and resolution plans. These steps include the following:

          The second, third and fourth quarters of 2010 and the first quarter of 2011 reflect progress made in implementing these plans. The following table highlights asset quality results achieved the past six quarters.

Regulatory Developments

Consent Order with Macatawa Bank and its Regulators

          On February 22, 2010, Macatawa Bank entered into a Consent Order (the "Consent Order") with the FDIC and OFIR, the primary banking regulators of the Bank. The Bank agreed to the terms of the Consent Order without admitting or denying any charges of unsafe or unsound banking practices. The Consent Order imposes no fines or penalties on the Bank. The Consent Order will remain in effect and enforceable until it is modified, terminated, suspended, or set aside by the FDIC and the OFIR. Macatawa Bank's customer deposits remain fully insured to the highest limit set by the FDIC. The Board of Directors views the requirements of the Consent Order as necessary components of its efforts to return Macatawa to profitability and pursue the long term success of Macatawa Bank for its shareholders, depositors, and customers.

          The Consent Order includes the following requirements, among others:

          The Company believes that, as of the date of this prospectus, the Bank was in compliance in all material respects with all of the provisions of the Consent Order, other than the minimum capital requirements.

TABLE OF CONTENTS

Written Agreement with the Company and its Regulator

          The Company has formally entered into a Written Agreement with the FRB with an effective date of July 23, 2010. Among other things, the Written Agreement provides that the Company:

          Each quarter we request approval from the FRB to make the next quarter's interest payment on our subordinated debt and are continuing to accrue the interest amounts due.

          Since the effective date of the Written Agreement, we have submitted our capital plan, cash flow projections and other reports in accordance with the timelines specified in the Written Agreement or agreed upon extensions. In addition, our senior management has met with and spoken to FRB representatives several times since the Written Agreement became effective. On November 15, 2010, we submitted a plan to maintain sufficient capital and have had several conversations with the FRB regarding the plan since that time. At the FRB's request, we submitted an updated draft of the capital plan on March 31, 2011. The FRB requested revisions to the draft capital plan and we submitted an updated draft incorporating those revisions on April 29, 2011. On February 11, 2011, we submitted to the FRB a written statement of the Company's planned sources and uses of cash for 2011. At the FRB's request, we submitted a plan for how the Company will meet its cash flow obligations for 2011 on March 31, 2011.

          Other than acceptance by the FRB of a capital plan and our plan for meeting cash flow obligations for 2011, the Company believes that, as of the date of this prospectus, it was in compliance in all material respects with all of the provisions of the Written Agreement.

Pending SEC Investigation

          We have been fully cooperating with the SEC, which is conducting a non-public fact-finding investigation into the circumstances surrounding the Company's restatement of earnings for the quarter ended June 30, 2008 and the Company's revision of its previously announced financial results for the quarter ended June 30, 2009. The SEC has not provided us with notice asserting that any violations of the securities laws have occurred, but there can be no

QUESTIONS AND ANSWERS RELATING TO THE OFFERINGS

What is the rights offering?

          We are distributing, at no charge, to holders of our common shares, non-transferable subscription rights to purchase our common shares. You will receive one subscription right for each common share you owned as of 5:00 p.m., Eastern Time, on May 2, 2011, the record date. The shares to be issued in the rights offering, like our existing common shares, are listed on The Nasdaq Global Select Market under the symbol "MCBC".

What is the subscription right?

          Each subscription right gives our shareholders the opportunity to purchase one share of our common stock at a subscription price of $2.30 per share. For example, if you owned 100 common shares as of May 2, 2011, you would have received 100 subscription rights and would have the right to purchase 100 common shares for $2.30 per share. You may exercise all or a portion of your subscription rights or you may choose not to exercise any subscription rights at all.

          If you are a registered holder of Macatawa Bank Corporation common stock, the number of shares of common stock you may purchase by exercising your subscription rights is indicated on the enclosed rights certificate. If you hold your shares in the name of a custodian bank, broker, dealer or other nominee, you will not receive a rights certificate. Instead, the Depositary Trust Company will issue rights to the nominee record holder for each common share that you own at the record date. If you are not contacted by your custodian bank, broker, dealer or other nominee, you should contact your nominee as soon as possible.

Is there an over-subscription privilege?

          No. If there are any shares that are offered but unsold in the rights offering, they will be offered in the public offering. Shareholders who wish to purchase a number of shares of common stock that is greater than the subscription rights issued to them may submit an expression of interest to purchase shares in the public offering. See "The Public Offering - How to Subscribe in the Public Offering" on page 51.

What is the public offering?

          We are also conducting an offering of common stock to the public, referred to as the public offering. In the public offering, we are offering for sale any shares not purchased in the rights offering, up to the total offering amount. The public offering will terminate at 5:00 p.m., Eastern Time, on June 20, 2011, unless we extend the offering period in our discretion. There is no guarantee that any shares will be available for purchase in the public offering.

Why are we conducting the offerings?

          We intend to use a portion of the net proceeds of the offerings to contribute to the capital of the Bank to increase the Bank's capital and regulatory capital ratios. As of March 31, 2011, the Bank needed a capital injection of approximately $14.0 million to comply with the Tier 1 Leverage Capital Ratio requirement and needed a capital injection of approximately $7.1 million to comply with the Total Risk Based Capital Ratio requirement of the Consent Order. We intend to retain a portion of the net proceeds at the Company to pay a portion of the Company's direct operating expenses while the Company is unable to fund those expenses with dividends from the Bank. Assuming all of the shares in the offerings are sold, the Company intends to contribute $30 million of the net proceeds from the offerings to the Bank. There is no assurance as to any particular level of proceeds from the offerings.

          Funds contributed to the Bank will be used by the Bank for general operating purposes which may include, among others, funding of loans, investment in securities, and payment of expenses. The proceeds of the offerings which are not contributed to the Bank will be used by the Company for general corporate purposes which may include, among others, payment of expenses, payment of interest on subordinated notes and trust preferred securities, and pursuing strategic opportunities which may be presented to the Company in the future.

          Our board of directors also considered several alternative capital raising methods prior to concluding that the rights offering, in conjunction with a public offering, was the appropriate option under the current circumstances. We believe that the offerings will strengthen our financial condition by generating additional cash and increasing our capital levels. It is possible that we will need to seek

How was the $2.30 per share subscription price determined?

          Our board of directors determined the terms of the offerings, including the subscription price, in its sole discretion on May 2, 2011. In determining the subscription price, the board of directors considered a number of factors, including:

          In conjunction with its review of these factors, the board of directors also reviewed our history and prospects, including our past and present earnings, our prospects for future earnings, and our current financial condition and regulatory status. The subscription price is not necessarily related to our book value, results of operations, cash flows, financial condition or net worth or any other established criteria of value and may or may not be considered the fair value of our common stock at the time the terms of the offerings were approved by our board of directors or during the offerings.

          A committee of the Board of Directors consisting only of independent directors who will not purchase shares in the offering ratified and approved the subscription price of $2.30 per share for the rights offering and the public offering.

How was the offering size determined?

          The Board of Directors determined that the Company's existing shareholders should have an opportunity to purchase substantially all of the shares of common stock that we are offering. The Board established the total offering size of $41 million by multiplying the offering price, as determined by the Board of Directors, by the approximate number of shares outstanding as of the May 2, 2011. A committee of the Board of Directors consisting only of independent directors who will not purchase shares in the offering ratified and approved the price, size and other aspects of the offerings.

          We do not expect that all shareholders will exercise all of their subscription rights. Any shares offered but not sold in the rights offering will be offered for sale in the public offering. The Board of Directors believes that even if the rights offering and the public offering are not fully subscribed, the offerings may be considered successful if we are able to address our capital needs. Please see "Our Capital Needs" on page 2.

Has our board of directors made a recommendation to our shareholders regarding the rights offering?

          No. Our board of directors is making no recommendation regarding your exercise of the subscription rights. Shareholders who exercise subscription rights risk investment loss on new money invested. We cannot predict the price at which our common shares will trade; therefore, we cannot assure you that the market price for our common shares will be above the subscription price or that anyone purchasing shares at the subscription price will be able to sell those shares in the future at the same price or a higher price. You are urged to make your decision based on your own assessment of our business and the rights offering and your ability to accept risk. See "Risk Factors" beginning on page 22 for a discussion of some of the risks involved in investing in our common shares.

Am I required to exercise all of the subscription rights I receive in the rights offering?

          No. You may exercise any number of your subscription rights, or you may choose not to exercise any subscription rights. If you do not exercise any subscription rights, the number of common shares you own will not change. However, if you choose not to exercise your subscription rights in full, your ownership interest measured as a percentage of our outstanding common shares will be diluted as a result of the rights offering.

TABLE OF CONTENTS

How soon must I act to exercise my subscription rights?

          If you received a rights certificate and elect to exercise any or all of your subscription rights, the subscription agent must receive your completed and signed rights certificate and full payment of the subscription price prior to the expiration of the rights offering, which is June 7, 2011, at 5:00 p.m., Eastern Time. If you hold your shares in the name of a custodian bank, broker, dealer or other nominee, your nominee may establish a deadline prior to 5:00 p.m., Eastern Time, on June 7, 2011, by which you must provide it with your instructions to exercise your subscription rights and payment for your shares. Our board of directors may, in its discretion, extend the rights offering one or more times. Our board of directors may cancel or amend the rights offering at any time. In the event that the rights offering is cancelled, all subscription payments received by the subscription agent will be returned, without interest, as soon as practicable.

          Although we will make reasonable attempts to provide this prospectus to holders of subscription rights, the rights offering and all subscription rights will expire at 5:00 p.m., Eastern Time on June 7, 2011 (unless extended), whether or not we have been able to locate each person entitled to subscription rights.

How do I exercise my subscription rights if I am a record shareholder?

          In certain cases, you may be required to provide additional documentation or signature guarantees.

          Please follow the delivery instructions on the rights certificate. Do not deliver rights offering documents to the Company or the Bank. You are solely responsible for completing delivery to the subscription agent of your subscription documents, rights certificate and payment. We urge you to allow sufficient time for delivery of your subscription materials to the subscription agent so that they are received by the subscription agent by 5:00 p.m., Eastern Time, on June 7, 2011.

          See "The Rights Offering - Exercising of Subscription Rights" on page 47.

What should I do if I want to participate in the rights offering, but my shares are held in the name of a custodian bank, broker, dealer or other nominee?

          If you hold your common shares through a custodian bank, broker, dealer or other nominee, then your nominee is the record holder of the shares you own. If you are not contacted by your nominee, you should contact your nominee as soon as possible. Your nominee must exercise the subscription rights on your behalf for the common shares you wish to purchase. You will not receive a rights certificate. Please follow the instructions of your nominee. Your nominee may establish a deadline that may be before the 5:00 p.m., Eastern Time, June 7, 2011 expiration date that we have established for the rights offering.

What should I do if I want to participate in the rights offering, but my shares are held in my account in the Company's 401(k) Plan?

          If you held shares of our common stock in your 401(k) Plan account as of the record date, you may exercise your subscription rights with respect to those shares of common stock by electing what amount (if any) of your subscription rights you would like to exercise by properly completing the rights certificate that is provided to you. You must return your properly completed form and payment to the subscription agent in the prescribed manner. For the purposes of the rights offering, you will be treated as a record shareholder, and any shares that you elect to purchase in the rights offering will be credited to you directly in book-entry form, and will not be credited to you in your 401(k) Plan account. You may not use funds in your 401(k) Plan account to purchase shares in the rights offering.

What should I do if I want to participate in the rights offering, but my subscription rights are held in my account in the Company's Employee Stock Purchase Plan?

          If you held shares of our common stock in your Macatawa Bank Employee Stock Purchase Plan account as of the record date, you may exercise your subscription rights with respect to those shares of common stock by electing what amount (if any) of your subscription rights you would like to exercise by properly completing the rights certificate that is provided to you. You must return your properly completed form and payment to the subscription

TABLE OF CONTENTS

May I transfer my subscription rights?

          No. You may not sell, transfer or assign your subscription rights to anyone. Subscription rights will not be listed on The Nasdaq Global Select Market or any other stock exchange or market. Rights certificates may only be completed by the shareholder who receives the certificate.

What form of payment is required to purchase shares in the rights offering?

          As described in the instructions accompanying the rights certificate, payments submitted to the subscription agent for shares in the rights offering must be made in full U.S. currency wire transfer or by personal check drawn on a U.S. bank payable to "Registrar and Transfer Company". If you send payment by personal check, payment will not be deemed to have been delivered to the subscription agent until the check has cleared. Please note that funds paid by personal check may take at least seven business days to clear, so you should submit your documents and personal check early enough to allow for clearance. See "The Rights Offering - Method of Payment" on page 48.

How do I purchase shares in the public offering?

          Prospective investors who wish to subscribe for shares in the public offering, including shareholders who wish to purchase more shares than entitled to in the rights offering, may complete the nonbinding expression of interest that accompanies this prospectus and return it to the Company before the expiration of the rights offering at 5:00 p.m., Eastern Time, on June 7, 2011, unless extended by us in our discretion.

          Expressions of interest are NOT binding on subscribers or the Company. Do NOT send payment for shares with an expression of interest. There can be no guarantee that any shares will be available for purchase in the public offering. Upon the completion of the rights offering, we will furnish to persons who have timely submitted an expression of interest a prospectus supplement that sets forth the results of the rights offering and the amount of unsubscribed shares accompanied by a subscription agreement. Upon receipt of the prospectus supplement, each subscriber will be asked to do the following:

          UPON RECEIPT BY US OF THE SUBSCRIPTION AGREEMENT, THE SUBSCRIPTION AGREEMENT WILL BECOME BINDING ON AND IRREVOCABLE BY THE SUBSCRIBER.

          Payment for shares purchased in the public offering must be made by wire transfer or certified check payable to Macatawa Bank Corporation. See "The Public Offering - How to Subscribe in the Public Offering" on page 51.

Are there any limits on the number of shares I may purchase in the offerings or own as a result of the offerings?

          We reserve the right to reject in whole or in part any or all exercise of subscription rights in the rights offering and any subscription in the public offering.

          A person, together with certain related persons and associates, may not purchase a number of shares such that upon completion of the offerings the person owns in excess of 4.9% of the Company's common stock outstanding. This limit is being imposed as a measure to help preserve the future availability of our deferred tax assets.

          We may elect not to sell shares of our common stock to any proposed purchaser in the rights offering or the public offering who, in our sole judgment, might be required to obtain prior clearance or approval from or submit a notice to any state or federal bank regulatory authority to acquire, own or control such shares if, as of the expiration of the rights offering or expiration of the public offering, as applicable, such clearance or approval has not been

          The Company may waive these limitations in its sole discretion. The Company reserves the right to allocate shares sold to investors in the public offering in its sole discretion and for any reason.

When will I receive my new shares?

          If you purchase common shares in the rights offering by submitting a rights certificate and payment, we will deliver your shares in book-entry form only or credit the account of the record holder against payment on or about June 10, 2011, subject to extensions and customary closing conditions. If you purchase shares in the public offering, we will deliver your shares in book-entry form only against payment on or about June 21, 2011, subject to extensions and customary closing conditions.

After I send in my payment and rights certificate, may I cancel my exercise of subscription rights?

          No. All exercises of subscription rights are irrevocable, unless the rights offering is terminated, even if you later learn information that you consider to be unfavorable to the exercise of your subscription rights. You should not exercise your subscription rights unless you are certain that you wish to purchase common shares in the rights offering.

If the offerings are not completed, will my subscription payment be refunded to me?

          Yes. The subscription agent will hold all funds it receives in a segregated bank account until completion of the rights offering. If the rights offering is not completed, all subscription payments received by the subscription agent will be returned, without interest, as soon as practicable. If your shares are held in the name of a custodian bank, broker, dealer or other nominee, it may take longer for you to receive the refund of your payment because the subscription agent will return payments through the record holder of your shares.

          If the public offering is not completed, the Company will return all payments received, without interest, as soon as practicable.

What fees or charges apply?

          We are not charging any fee or sales commission to issue subscription rights to you or to issue shares to you in the offerings (other than the subscription price). If you exercise subscription rights through a custodian bank, broker, dealer or other nominee, you are responsible for paying any fees your nominee may charge you.

Whom should I contact if I have other questions?

RISK FACTORS

          An investment in our common stock involves significant risks. You should consider carefully the risk factors included below and those discussed under the caption "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2010, together with all of the other information included in or incorporated by reference into this prospectus, before making a decision to invest in our common stock. This prospectus also contains forward-looking statements that involve risks and uncertainties. If any of the matters included in the following information about risk factors were to occur, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. In such case, you may lose all or a substantial part of your investment.

Risks Related To the Company's Business

Other than the last three quarters of 2010 and the first quarter of 2011, our results of operations have not been profitable in recent periods and we may incur additional losses during 2011.

          We were profitable in the second, third and fourth quarters of 2010 and the first quarter of 2011, but we had posted a high consolidated net loss in each of the preceding six consecutive quarters, and a total consolidated net loss during that time period of $123.5 million. Net income for the second quarter of 2010 was largely due to a $2.7 million gain on the sale of securities. Net income for the fourth quarter of 2010 was impacted by a $574,000 gain on the sale of a bank owned property. The last three quarters of 2010 and the first quarter of 2011 were positively affected by reductions in the allowance for loan losses. Total nonperforming assets as of March 31, 2011 remained high and related costs were also elevated. There is no assurance that our results of operations will stay profitable in the short term or at all. We have recorded provisions for loan losses of $22.5 million and $74.3 million, respectively, for the years ended December 31, 2010 and 2009. Costs associated with the administration and disposition of nonperforming assets were $15.4 million and $11.4 million, respectively, for the years ended December 31, 2010 and 2009. In light of the current economic environment, significant additional provisions for loan losses and nonperforming asset costs may yet be necessary. As a result, we may incur significant additional credit costs in 2011 or beyond, which could adversely impact our financial condition, results of operations, and the value of our common stock.

The Company's past operating results may not be indicative of its future operating results.

          The Company's strategic direction and focus has turned from growth to improving its internal operations, including complying with the Consent Order and the Written Agreement, working out of its problem loans and assets and returning the Company to profitable operations. The Company will not be able to achieve the historical rate of growth it experienced prior to the 2008 economic downturn, may not even be able to grow its business at all and may be forced to continue to shrink assets to maintain regulatory capital ratios. Various factors, many of which are discussed in more detail in the risk factors below, that may impede or prohibit the Company's ability to grow include the impact of elevated levels of nonperforming assets, the inability to maintain or access additional capital and liquidity sources, economic conditions, regulatory and legislative considerations and competition. If the Company experiences a significant decrease in its size, the Company's results of operations and financial condition could be adversely affected due to the percentage of its operating costs being fixed expenses.

Our elevated level of nonperforming assets and other problem loans could continue to have an adverse effect on the Company's results of operations and financial condition.

          Our nonperforming assets (which includes non-accrual loans, foreclosed properties and other accruing loans past due 90 days or more) were approximately $121.1 million at March 31, 2011. These elevated levels could continue to negatively impact operating results through higher loan losses, lost interest and higher costs to administer problem assets. Until these elevated levels of problem assets are reduced, the Company could continue to record operating losses that further materially deteriorate the Company's financial condition and reduce capital levels, further exposing the Company to additional risk factors discussed below.

TABLE OF CONTENTS

National, state and local economic conditions could have a material adverse effect on the Company's results of operations and financial condition.

          The results of operations for financial institutions, including our Bank, may be materially and adversely affected by changes in prevailing national, state and local economic conditions. Our profitability is heavily influenced by the quality of the Company's loan portfolio and the stability of the Company's deposits. Unlike larger national or regional banks that are more geographically diversified, the Company provides banking and financial services to customers primarily in Ottawa, Kent and Allegan Counties of Western Michigan. The local economic conditions in these areas have a significant impact on the demand for the Company's products and services, and the ability of the Company's customers to repay loans, the value of the collateral securing loans and the stability of the Company's deposit funding sources. A significant decline in general economic conditions, caused by inflation, recession, acts of terrorism, outbreak of hostilities or other international or domestic occurrences, unemployment, changes in securities, financial, capital or credit markets or other factors, could impact national and local economic conditions and have a material adverse effect on the Company's results of operations and financial condition.

Our credit losses could increase and our allowance for loan losses may not be adequate to cover actual loan losses.

          The risk of nonpayment of loans is inherent in all lending activities and nonpayment of loans may have a material adverse effect on our earnings and overall financial condition, and the value of our common stock. We make various assumptions and judgments about the collectability of our loan portfolio and provide an allowance for potential losses based on a number of factors. If our assumptions are wrong, our allowance for loan losses may not be sufficient to cover our losses, which could have an adverse affect on our operating results, and may cause us to increase the allowance in the future. The actual amount of future provisions for loan losses cannot now be determined and may exceed the amounts of past provisions. Federal banking regulators, as an integral part of their supervisory function, periodically review our allowance for loan losses. These regulatory agencies may require us to increase our provision for loan losses or to recognize further loan charge-offs based upon their judgments, which may be different from ours. Any increase in the allowance for loan losses could have a negative effect on our regulatory capital ratios, net income, financial condition and results of operations.

Macatawa Bank Corporation has only limited cash and cash equivalents available at the holding company level. If Macatawa Bank Corporation's cash and cash equivalents were to become exhausted, it would be unable to meet its financial obligations as they come due rendering it insolvent.

          Macatawa Bank Corporation has only limited cash and cash equivalents available at the holding company level. At April 30, 2011, Macatawa Bank Corporation had cash and cash equivalents of $125,000 and $579,000 at March 31, 2011 and December 31, 2010, respectively. In order to temporarily replenish Macatawa Bank Corporation's liquidity pending the offerings, we issued and sold a 2% Subordinated Note in the amount of $1 million to a director of the Company on April 21, 2011, bringing the balance of cash and equivalents to $1,066,971 at April 30, 2011. If completion of the offerings is materially delayed or does not occur, or if participation in the offerings is less than expected, Macatawa Bank Corporation's cash and cash equivalents could become exhausted, unless it is able to access additional funds through other capital raising efforts or other funding sources. If Macatawa Bank Corporation's cash and cash equivalents become exhausted, it would be unable to meet its financial obligations as they come due rendering it insolvent. If Macatawa Bank Corporation becomes insolvent, it could be subject to voluntary or involuntary bankruptcy or similar insolvency proceedings and its business, financial condition and results of operations would be materially and adversely affected.

If the condition of the Bank's loan portfolio worsens, its ability to borrow funds from the Federal Home Loan Bank and Federal Reserve Bank could be adversely affected, which could materially adversely affect the Bank's liquidity position.

          As part of its liquidity management, the Bank borrows funds from the Federal Home Loan Bank and has the ability to borrow from the Federal Reserve Bank. The borrowed funds are collateralized by certain investment securities and qualifying residential and commercial real estate loans. The Bank is permitted to borrow an amount of funds up to a certain percentage of the total investment securities and loans pledged as collateral. The Federal Home Loan Bank and Federal Reserve Bank will not accept as collateral any loan that is rated as a 5 or worse on our

TABLE OF CONTENTS

The Bank cannot accept, renew or roll over brokered deposits without a waiver from the FDIC, which could materially adversely affect the Bank's liquidity position.

          Because the Bank is subject to the Consent Order, the Bank cannot be categorized as "well-capitalized," regardless of actual capital levels. As of the date of this prospectus, the Bank was categorized as "adequately capitalized." As a result, the Bank cannot accept, renew or roll over any brokered deposit unless it has applied for and been granted a waiver of this prohibition by the FDIC. It is not likely that the Bank will be granted a waiver of this prohibition. At March 31, 2011, the Bank's brokered deposits totaled $42.6 million and represented 3% of deposits. All of the Bank's brokered deposits are scheduled to mature in 2011. If the Bank is not able to replace the funding required for maturing brokered deposits, the Bank's liquidity position could be materially adversely affected.

We are subject to liquidity risk in our operations, which could adversely affect our ability to fund various obligations.

          Liquidity risk is the possibility of being unable to meet obligations as they come due, pay deposits when withdrawn, and fund loan and investment opportunities as they arise because of an inability to liquidate assets or obtain adequate funding on a timely basis, at a reasonable cost and within acceptable risk tolerances. Liquidity is required to fund various obligations, including credit obligations to borrowers, mortgage originations, withdrawals by depositors, repayment of debt, operating expenses and capital expenditures. Liquidity of the Bank is derived primarily from retail deposit growth and retention, principal and interest payments on loans and investment securities, net cash provided from operation and access to other funding sources. Liquidity is essential to our business. We must maintain sufficient funds to respond to the needs of depositors and borrowers. An inability to raise funds through deposits, borrowings, the sale or pledging as collateral of loans and other assets could have a material adverse effect on our liquidity. An inability to retain the current level of deposits, including the loss of one or more of the Bank's larger deposit relationships, could have a material adverse effect on the Bank's liquidity. Our access to funding sources in amounts adequate to finance activities could be impaired by factors that affect us specifically or the financial services industry in general. Factors that could detrimentally impact our access to liquidity sources include a decrease in the level of the business activity due to a market down turn or regulatory action that limits or eliminates access to alternate funding sources, including brokered deposits discussed above. Our ability to borrow could also be impaired by factors that are nonspecific to the Company, such as severe disruption of the financial markets or negative expectations about the prospects for the financial services industry as a whole.

We are not in compliance with the Consent Order. This could result in enforcement action against us.

          The Bank is subject to the Consent Order with the FDIC and OFIR. The Bank is required to have and maintain a Tier 1 Leverage Capital Ratio of at least 8% and a Total Risk Based Capital Ratio of at least 11%. The Bank was not in compliance with these capital ratios at March 31, 2011. We are evaluating alternatives to reach and maintain the capital levels required by the Consent Order. Achievement of these capital levels could be impacted, positively or negatively, as a result of uncertainties, including, but not limited to, earnings levels, changing economic conditions, asset quality and property values. A failure to raise additional capital to satisfy the capital levels required by the Consent Order could materially adversely affect our ability to maintain our current level of assets and to further expand our operations through organic growth. In addition, the Bank could become subject to an enforcement action, which could result in removal of directors, officers, employees and institution affiliated parties, and the imposition of civil money penalties and even ultimately closure of the Bank.

          The Company believes that, as of the date of this prospectus, the Bank was in compliance in all material respects with all of the provisions of the Consent Order, other than the minimum capital requirements.

TABLE OF CONTENTS

Failure to comply with the Written Agreement could result in enforcement action against us.

          The Company is subject to the Written Agreement with the FRB. Under the Written Agreement, among other things, the Company must submit to the FRB an acceptable written plan to maintain sufficient capital on a consolidated basis and a written statement of the Company's planned sources and uses of cash for debt service, operating expenses, and other purposes for 2010 and subsequent years.

          Since the effective date of the Written Agreement, we have submitted our capital plan, cash flow projections and other reports in accordance with the timelines specified in the Written Agreement or agreed upon extensions. In addition, our senior management has met with and spoken to FRB representatives several times since the Written Agreement became effective. On November 15, 2010, we submitted a plan to maintain sufficient capital and have had several conversations with the FRB regarding the plan since that time. At the FRB's request, we submitted an updated draft of the capital plan on March 31, 2011. The FRB requested revisions to the draft capital plan and we submitted an updated draft incorporating those revisions on April 29, 2011. On February 11, 2011, we submitted to the FRB a written statement of the Company's planned sources and uses of cash for 2011. At the FRB's request, we submitted a plan for how the Company will meet its cash flow obligations for 2011 on March 31, 2011.

          Other than acceptance by the FRB of its capital plan and plan for meeting cash flow obligations for 2011, the Company believes that, as of the date of this prospectus, it was in compliance in all material respects with all of the provisions of the Written Agreement. The failure of the Company to comply with the terms of the Written Agreement could result in proceedings to enforce the Written Agreement. Such proceedings could result in removal of directors, officers, employees and institution affiliated parties, the imposition of civil money penalties and other adverse actions.

A pending SEC investigation may subject us to significant costs and could divert management attention.

          We have been fully cooperating with the SEC, which is conducting a non-public fact-finding investigation into the circumstances surrounding the Company's restatement of earnings for the quarter ended June 30, 2008 and the Company's revision of its previously announced financial results for the quarter ending June 30, 2009. The SEC has not provided us with notice asserting that any violations of the securities laws have occurred, but there can be no assurance as to the outcome of its investigation. We have already incurred, and expect to continue to incur, significant legal expenses arising from the investigation. If the SEC were to institute legal action, we could face fines and penalties in an amount that could be material and we could be required to take remedial actions determined by the SEC or a court.

Our construction and development lending has exposed us to significant risks and has resulted in a disproportionate amount of the increase in our provision for loan losses in recent periods.

          Construction and development loans consist of loans to commercial customers for the construction of their business facilities. They also include construction loans to builders and developers for the construction of one- to four-family residences and the development of one- to four-family lots, residential subdivisions, condominium developments and other commercial developments. This portfolio has been particularly adversely affected by job losses, declines in real estate value, declines in home sale volumes, and declines in new home building. Declining real estate values have resulted in sharp increases in losses, particularly in the land development and construction loan portfolios to residential developers. This type of lending is generally considered to have more complex credit risks than traditional single-family residential lending because the principal is concentrated in a limited number of loans with repayment dependent on the successful completion and sales of the related real estate project. Consequently, these loans are often more sensitive to adverse conditions in the real estate market or the general economy than other real estate loans. These loans are generally less predictable and more difficult to evaluate and monitor and collateral may be difficult to dispose of in a market decline. Additionally, we may experience significant construction loan losses if independent appraisers or project engineers inaccurately estimate the cost and value of construction loan projects. The Company curtailed this type of lending in 2008. During 2009 and 2010, the Company also made a significant effort to reduce its exposure to residential land development and other construction and development loans.

TABLE OF CONTENTS

          Construction and development loans have contributed disproportionately to the increase in our provisions for loan losses in recent periods. As of March 31, 2011, we had approximately $60.4 million in construction and development loans outstanding, or approximately 5.2% of our loan portfolio. Approximately $28.9 million, or 49.8%, of our net charge-offs during 2009 and approximately $9.2 million, or 31.0%, of our net charge-offs during 2010 were attributable to construction and development loans. Further deterioration in our construction and development loan portfolio could result in additional increases in the provision for loan losses and an increase in charge-offs, all of which could have a material adverse effect on our financial condition and results of operations.

We have significant exposure to risks associated with commercial and residential real estate.

          A substantial portion of our loan portfolio consists of commercial and residential real estate-related loans, including real estate development, construction and residential and commercial mortgage loans. As of March 31, 2011, we had approximately $625.7 million of commercial real estate loans outstanding, which represented approximately 54% of our loan portfolio. As of that same date, we had approximately $127.4 million in residential real estate loans outstanding, or approximately 11% of our loan portfolio. Consequently, real estate-related credit risks are a significant concern for us. The adverse consequences from real estate-related credit risks tend to be cyclical and are often driven by national economic developments that are not controllable or entirely foreseeable by us or our borrowers. General difficulties in our real estate markets have recently contributed to significant increases in our nonperforming loans, charge-offs, and decreases in our income.

Commercial loans may expose us to greater financial and credit risk than other loans.

          Our commercial loan portfolio, including commercial mortgages, was approximately $886.4 million at March 31, 2011, comprising approximately 77% of our total loan portfolio. Commercial loans generally carry larger loan balances and can involve a greater degree of financial and credit risk than other loans. Any significant failure to pay on time by our customers would hurt our earnings. The increased financial and credit risk associated with these types of loans are a result of several factors, including the concentration of principal in a limited number of loans and borrowers, the size of loan balances, the effects of general economic conditions on income-producing properties and the increased difficulty of evaluating and monitoring these types of loans. In addition, when underwriting a commercial or industrial loan, we may take a security interest in commercial real estate, and, in some instances upon a default by the borrower, we may foreclose on and take title to the property, which may lead to potential financial risks for us under applicable environmental laws. If hazardous substances were discovered on any of these properties, we may be liable to governmental agencies or third parties for the costs of remediation of the hazard, as well as for personal injury and property damage. Many environmental laws can impose liability regardless of whether we knew of, or were responsible for, the contamination.

Our loan portfolio has and will continue to be affected by the ongoing correction in residential real estate prices and reduced levels of home sales.

          Loans to residential developers involved in the development or sale of 1-4 family residential properties were approximately $60.4 million, $95.7 million, $153.3 million and $204.4 million at March 31, 2011, December 31, 2010, 2009 and 2008, respectively. There continues to be a general slowdown in the housing market in our market area, reflecting declining prices and excess inventories of houses to be sold. As a result, home builders have shown signs of financial deterioration. We expect the home builder market to continue to be volatile and anticipate continued pressure on the home builder segment. As we continue our on-going portfolio monitoring, we will make credit and reserve decisions based on the current conditions of the borrower or project combined with our expectations for the future. If the deterioration in the housing market continues, we could experience higher charge-offs and delinquencies in this portfolio.

We may face increasing pressure from historical purchasers of our residential mortgage loans to repurchase those loans or reimburse purchasers for losses related to those loans.

          We generally sell the fixed rate long-term residential mortgage loans we originate on the secondary market and retain adjustable rate mortgage loans for our portfolios. In response to the financial crisis, we believe that purchasers of residential mortgage loans, such as government sponsored entities, are increasing their efforts to seek to require sellers of residential mortgage loans to either repurchase loans previously sold or reimburse purchasers for

TABLE OF CONTENTS

          For the five-year period ended December 31, 2010, the Company has sold an aggregate of $533.1 million of residential mortgage loans on the secondary market. On March 1, 2011, the Company received a make-whole request for $45,000 related to one previously sold loan. This request was subsequently withdrawn. As of the date of this prospectus, the Company had no pending make whole requests or other claims for reimbursement, and had not realized any loss, related to residential mortgage loans sold on the secondary market during the five-year period ended December 31, 2010.

Changes in interest rates may negatively affect our earnings and the value of our assets.

          Our earnings and cash flows depend substantially upon our net interest income. Net interest income is the difference between interest income earned on interest-earnings assets, such as loans and investment securities, and interest expense paid on interest-bearing liabilities, such as deposits and borrowed funds. Interest rates are sensitive to many factors that are beyond our control, including general economic conditions, competition and policies of various governmental and regulatory agencies and, in particular, the policies of the Federal Reserve Board. Changes in monetary policy, including changes in interest rates, could influence not only the interest we receive on loans and investment securities and the amount of interest they pay on deposits and borrowings, but such changes could also affect: (i) our ability to originate loans and obtain deposits; (ii) the fair value of our financial assets and liabilities, including our securities portfolio; and (iii) the average duration of our interest-earning assets. This also includes the risk that interest-earning assets may be more responsive to changes in interest rates than interest-bearing liabilities, or vice versa (repricing risk), the risk that the individual interest rates or rates indices underlying various interest-earning assets and interest-bearing liabilities may not change in the same degree over a given time period (basis risk), and the risk of changing interest rate relationships across the spectrum of interest-earning asset and interest-bearing liability maturities (yield curve risk), including a prolonged flat or inverted yield curve environment. Any substantial, unexpected, prolonged change in market interest rates could have a material adverse affect on our financial condition and results of operations.

The Dodd-Frank Act may adversely impact the Company's results of operations, financial condition or liquidity.

          On July 21, 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Dodd-Frank Act"), was signed into law by President Obama. The Dodd-Frank Act represents a comprehensive overhaul of the financial services industry within the United States, establishes the new federal Bureau of Consumer Financial Protection (the "BCFP"), and will require the BCFP and other federal agencies to implement many new and significant rules and regulations. At this time, it is difficult to predict the extent to which the Dodd-Frank Act or the resulting rules and regulations will impact the Company's and the Bank's business. Compliance with these new laws and regulations will likely result in additional costs, which could be significant, and could adversely impact the Company's results of operations, financial condition or liquidity.

We are subject to significant government regulation, and any regulatory changes may adversely affect us.

          The banking industry is heavily regulated under both federal and state law. These regulations are primarily intended to protect customers, not our creditors or shareholders. We are subject to extensive regulation by the Federal Reserve, the FDIC and OFIR, in addition to other regulatory and self-regulatory organizations. Regulations affecting banks and financial services companies undergo continuous change, and we cannot predict the ultimate effect of such changes, which could have a material adverse effect on our profitability or financial condition.

TABLE OF CONTENTS

The Company could be adversely affected by the soundness of other financial institutions, including defaults by larger financial institutions.

          The Company's ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services institutions are interrelated as a result of credit, trading, clearing, counterparty or other relationships between financial institutions. The Company has exposure to multiple counterparties, and the Company routinely executes transactions with counterparties in the financial industry. As a result, defaults by, or even rumors or questions about, one or more financial services institutions, or the financial services industry generally, have led to market-wide liquidity problems and could lead to losses or defaults by the Company or by other institutions. This is sometimes referred to as "systemic risk" and may adversely affect financial intermediaries, such as clearing agencies, clearing houses, banks, securities firms and exchanges, with which the Company interacts on a daily basis, and therefore could adversely affect the Company.

The Bank may be required to pay additional insurance premiums to the FDIC, which could negatively impact earnings.

          Recent insured institution failures, as well as deterioration in banking and economic conditions, have significantly increased FDIC loss provisions, resulting in a decline in the designated reserve ratio to historical lows. The reserve ratio may continue to decline in the future. In addition, the limit on FDIC coverage has been increased to $250,000. These developments have caused the premiums assessed to the Bank by the FDIC to increase. Further, depending upon any future losses that the FDIC insurance fund may suffer, there can be no assurance that there will not be additional premium increases in order to replenish the fund. The FDIC may need to set a higher base rate schedule or impose special assessments due to future financial institution failures and updated failure and loss projections. Potentially higher FDIC assessment rates could have an adverse impact on our results of operations.

The proposed offerings may increase the risk of an "ownership change" for purposes of Section 382 of the Internal Revenue Code, which may materially impair our ability to use our net operating loss carryforward.

          Our ability to use our net operating loss carryforward to offset future taxable income will be limited if we experience an "ownership change" as defined in Section 382 of the Internal Revenue Code. In general, an ownership change will occur if there is a cumulative increase in our ownership by "5-percent shareholders" (as defined in the Code) that exceeds 50 percentage points over a rolling three-year period. A corporation that experiences an ownership change will generally be subject to an annual limitation on the use of its pre-ownership change deferred tax assets equal to the equity value of the corporation immediately before the ownership change, multiplied by the long-term tax-exempt rate, which is currently 4.47% for ownership changes occurring in February 2011.

          The offering could cause us to experience an "ownership change" as defined for U.S. federal income tax purposes. Even if the offerings do not cause us to experience an "ownership change," the issuance of our shares of common stock in the offerings materially increases the risk that we could experience an "ownership change" in the future. As a result, issuances or sales of common stock or other securities in the future, or certain other direct or indirect changes in ownership, could result in an "ownership change" under Section 382 of the Code. If an "ownership change" occurs, we could realize a permanent loss of a significant portion of our U.S. federal deferred tax assets (related to net operating loss carryforwards totaling $19.0 million at December 31, 2010) and lose certain built-in losses that have not been recognized for tax purposes. The amount of the permanent loss would depend on the size of the annual limitation (which is in part a function of our market capitalization at the time of an "ownership change") and the remaining carry forward period (U.S. federal net operating losses generally may be carried forward for a period of 20 years).

          Due to the losses incurred in recent years and in the first quarter of 2010, we continue to maintain a full valuation allowance on our entire deferred tax asset. If an "ownership change" had occurred on December 31, 2010, there would have been no direct financial impact because the asset is fully reserved. However, the ownership change would have affected the amount of valuation allowance we may be able to reverse in the future.

TABLE OF CONTENTS

We rely heavily on our management and other key personnel, and the loss of any of them may adversely affect our operations.

          We are and will continue to be dependent upon the services of our management team and other key personnel. Losing the services of one or more key members of our management team could adversely affect our operations.

Our controls and procedures may fail or be circumvented.

          Management regularly reviews and updates our internal controls, disclosure controls and procedures, and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. If we fail to identify and remediate control deficiencies, it is possible that a material misstatement of interim or annual financial statements will not be prevented or detected on a timely basis. In addition, any failure or circumvention of our other controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, results of operations and financial condition.

We may be a defendant in a variety of litigation and other actions, which may have a material adverse effect on our financial condition and results of operations.

          We may be involved from time to time in a variety of litigation arising out of our business. Our insurance may not cover all claims that may be asserted against us, and any claims asserted against us, regardless of merit or eventual outcome, may harm our reputation or cause us to incur unexpected expenses, which could be material in amount. Should the ultimate expenses, judgments or settlements in any litigation exceed our insurance coverage, they could have a material adverse effect on our financial condition and results of operations. In addition, we may not be able to obtain appropriate types or levels of insurance in the future, nor may it be able to obtain adequate replacement policies with acceptable terms, if at all.

Our future success is dependent on our ability to compete effectively in the highly competitive banking industry.

          We face substantial competition in all phases of our operations from a variety of different competitors. Our future growth and success will depend on our ability to compete effectively in this highly competitive environment. We compete for deposits, loans and other financial services with numerous Michigan-based and out-of-state banks, thrifts, credit unions and other financial institutions as well as other entities which provide financial services. Some of the financial institutions and financial services organizations with which we compete are not subject to the same degree of regulation as we are. Most of our competitors have been in business for many years, have established customer bases, are larger, and have substantially higher lending limits than we do. The financial services industry is also likely to become more competitive as further technological advances enable more companies to provide financial services.

Evaluation of investment securities for other-than-temporary impairment involves subjective determinations and could materially impact our results of operations and financial condition.

          The evaluation of impairments is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether declines in the fair value of investments should be recognized in current period earnings. The risks and uncertainties include changes in general economic conditions, the issuer's financial condition or future recovery prospects, the effects of changes in interest rates or credit spreads and the expected recovery period. Estimating future cash flows involves incorporating information received from third-party sources and making internal assumptions and judgments regarding the future performance of the underlying collateral and assessing the probability that an adverse change in future cash flows has occurred. The determination of the amount of other-than-temporary impairments is based upon our periodic evaluation and assessment of known and inherent risks associated with the respective asset class. Such evaluations and assessments are revised as conditions change and new information becomes available. Our management considers a wide range of factors about the security issuer and uses reasonable judgment in evaluating the cause of the decline in the estimated fair value of the security and in assessing the prospects for recovery. Inherent in management's evaluation of the security are assumptions and estimates about the operations of the issuer and its future earnings potential. Impairments to the

TABLE OF CONTENTS

We depend upon the accuracy and completeness of information about customers.

          In deciding whether to extend credit to customers, we may rely on information provided to us by our customers, including financial statements and other financial information. We may also rely on representations of customers as to the accuracy and completeness of that information and, with respect to financial statements, on reports of independent auditors. Our financial condition and results of operations could be negatively impacted to the extent that we extend credit in reliance on financial statements or other information provided by customers that is false or misleading.

We continually encounter technological change, and we may have fewer resources than our competitors to continue to invest in technological improvements.

          The banking industry is undergoing rapid technological changes with frequent introductions of new technology-driven products and services. In addition to better serving customers, the effective use of technology increases efficiency and enables financial institutions to reduce costs. Our future success will depend, in part, on our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience as well as to create additional efficiencies in our operations. Many of our competitors have substantially greater resources to invest in technological improvements. There can be no assurance that we will be able to effectively implement new technology-driven products and services or be successful in marketing such products and services to our customers.

Risks Associated With the Offerings and the Company's Stock

The future price of the shares of common stock may be less than the purchase price per share in the offerings.

          If you purchase shares of common stock in either offering, you may not be able to sell them later at or above the purchase price. The actual market price of our common stock could be subject to wide fluctuations in response to numerous factors, some of which are beyond our control. These factors include, among other things:

          Once you exercise your subscription rights or subscribe for shares in the public offering, you may not revoke your subscription. If you exercise your subscription rights or subscribe for shares in the public offering and, afterwards, the public trading market price of our shares of common stock decreases below the subscription price, you will have committed to buying shares of our common stock at a price above the prevailing market price and could have an immediate unrealized loss. We cannot assure you that the market price of our shares of common stock will not decline after you exercise your subscription rights or subscribe for shares in the public offering. Moreover, we cannot assure you that following the exercise of your subscription rights or subscription for shares in the public offering you will be able to sell your common stock at a price equal to or greater than the subscription price.

The subscription price determined for the offerings is not an indication of the fair value of our common stock.

          In determining the subscription price for the offerings, the board of directors considered a number of factors, including: the price at which shareholders and prospective shareholders might be purchase shares, historical and current trading prices for our common stock, the need for liquidity and capital and the desire to provide an opportunity to our shareholders to participate in the rights offering on a pro rata basis. In conjunction with its review

TABLE OF CONTENTS

The rights offering does not contain a minimum offering amount requirement. Your investment is subject to loss if we are unable to meet the capital requirements of the Consent Order.

          The rights offering does not contain a minimum subscription condition. Shareholders who subscribe could continue to own shares in the Company when it and the Bank do not satisfy all minimum regulatory capital requirements. A failure to meet minimum regulatory capital requirements could result in significant enforcement actions against the Company and the Bank, including a regulatory takeover of the Bank, in which case shareholders would receive little if anything for their investment.

The Company may issue additional shares of its common stock in the future, which could dilute a shareholder's ownership of common stock.

          The Company's articles of incorporation authorize its Board of Directors, without shareholder approval, to, among other things, issue additional shares of common or preferred stock. The issuance of any additional shares of common or preferred stock could be dilutive to a shareholder's ownership of Company common stock. The Company may offer additional shares of its common stock in exchange for its outstanding 11% Subordinated Notes due 2017 and may seek to issue additional shares of common stock in exchange for some or all outstanding shares of its preferred stock. In addition, the holder of the Company's 2% Subordinated Note due 2018 has a continuing right to convert the 2% Subordinated Note into shares of common stock in accordance with the terms of the 2% Subordinated Note. The holder also may purchase shares in the public offering and pay the cash price of any shares purchased by delivering the 2% Subordinated Note to the Company. The holder of the 2% Subordinated Note has informed the Company that he intends to purchase shares in the public offering and pay the cash price by delivering the 2% Subordinated Note to the Company.

          As of the date of this prospectus, subordinated notes (including the 11% Subordinated Notes and the 2% Subordinated Note) having an aggregate principal amount of $2,650,000 were outstanding. Other than the offerings, a possible exchange offer for the 11% Subordinated Notes, a possible exchange offer for preferred stock, and the possible conversion of the 2% Subordinated Note by the holder, the Company has no present plans to issue any additional shares of common stock.

          To the extent that the Company issues options or warrants to purchase common stock in the future and the options or warrants are exercised, the Company's shareholders may experience further dilution. Holders of shares of Company common stock have no preemptive rights that entitle holders to purchase their pro rata share of any offering of shares of any class or series and, therefore, shareholders may not be permitted to invest in future issuances of Company common or preferred stock.

          Because of its capital requirements, the Company may find it necessary to sell common stock to raise capital under circumstances and at prices which result in extreme dilution.

The offerings will dilute the ownership percentage of our existing shareholders and the ownership of our common stock may change significantly.

          We intend to raise significant capital through the offerings. Our directors and executive officers and individuals who reside in our markets currently hold a significant percentage of our common stock. Upon the successful completion of the offerings, the ownership percentage of existing shareholders will be diluted unless they purchase shares in the offerings in an amount proportional to their existing ownership. As a result, following the offerings, a significant portion of our common stock may be held by individuals and institutions outside of our market area whose interests may differ from our current shareholders. In addition, one or more individuals or institutions may seek to acquire a significant percentage of ownership in our common stock in the offerings, subject to any applicable regulatory approvals and the limitations set forth in this Prospectus. Those shareholders may have

TABLE OF CONTENTS

Exercise of our outstanding Warrants to purchase common stock or conversion of our outstanding preferred stock could substantially dilute a shareholder's ownership of common stock.

          We have issued Warrants to purchase a total of 1,478,811 shares of our common stock at an exercise price of $9.00 per share. Additional information about the Warrants may be found under the heading "Description of Capital Stock."

          We have outstanding 31,290 shares of Class A Preferred Stock, which are convertible into approximately 3,496,032 shares of our common stock at a conversion price of $8.95 per share. We have outstanding 2,600 shares of Class B Preferred Stock, which are convertible into approximately 433,333 shares of our common stock at a conversion price of $6.00 per share. Additional information about the preferred stock may be found under the heading "Description of Capital Stock."

          The exercise or conversion, in whole or in part, of these securities into shares of our common stock could substantially dilute a shareholder's ownership of common stock.

The Company's ability to pay dividends is limited and it may be unable to pay future dividends.

          We have suspended payment of dividends on our common and preferred stock in order to preserve capital and we do not expect to resume payment of dividends in the near term. Our ability to pay dividends is limited by regulatory restrictions and the need to maintain sufficient regulatory capital. The ability of the Bank to pay dividends to Macatawa Bank Corporation is limited by its obligation to maintain sufficient capital and by other general restrictions on dividends that are applicable to us. Under Michigan law, the Bank is restricted from paying dividends to the Company until its deficit retained earnings has been restored. The Bank had a retained deficit of approximately $37.9 million at March 31, 2011.

          In addition, the Company may not pay dividends on shares of common stock if the Company has not paid full cash dividends for the most recently completed dividend period for both the Series A and Series B Preferred Stock. Additional information on restrictions on payments of dividends by us may be found in Item 1 of the Company's Annual Report on Form 10-K for the year ended December 31, 2010 under the headings "Regulatory Developments" and "Supervision and Regulation," in Item 7 of that report under the under the heading "Capital Resources" included in "Management's Discussion and Analysis of Results of Operations and Financial Condition" and in Item 8 of that report in Notes 1 and 18 to the Consolidated Financial Statements, and is here incorporated by reference.

You may not revoke your subscription, but we may terminate the offerings.

          Once you have exercised your subscription rights or subscribed for shares in the public offering, you may not revoke the subscription even if you learn information about us that you consider to be unfavorable. We may terminate the offerings at our discretion. If we terminate either offering, we will not have any obligation to you with respect to the rights except to return any payment received, without interest or penalty.

Although publicly traded, our common stock has substantially less liquidity than the average liquidity of stocks listed on The Nasdaq Global Select Market.

          Although our common stock is listed for trading on The Nasdaq Global Select Market our common stock has substantially less liquidity than the average liquidity for companies listed on The Nasdaq Global Select Market. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the marketplace of willing buyers and sellers of our common stock at any given time. This marketplace depends on the individual decisions of investors and general economic and market conditions over which we have no control. This limited market may affect your ability to sell your shares on short notice, and the sale of a large

TABLE OF CONTENTS

The Company's common stock is not insured by any governmental entity.

          Our common stock is not a deposit account or other obligation of any bank and is not insured by the FDIC or any other governmental entity. Investment in Company common stock is subject to risk, including possible loss.

The Company may issue debt and equity securities that are senior to Company common stock as to distributions and in liquidation, which could negatively affect the value of Company common stock.

          The Company has in the past and may in the future increase its capital by entering into debt or debt-like financing or issuing debt or equity securities, which could include issuances of senior notes, subordinated notes, preferred stock or common stock. In the event of the Company's liquidation, its lenders and holders of its debt securities would receive a distribution of the Company's available assets before distributions to the holders of Company common stock. The Company's decision to incur debt and issue securities in future offerings will depend on market conditions and other factors beyond its control. The Company cannot predict or estimate the amount, timing or nature of its future offerings and debt financings. Future offerings could reduce the value of shares of Company common stock and dilute a shareholder's interest in the Company.

Our articles of incorporation and bylaws and Michigan laws contain certain provisions that could make a takeover more difficult.

          Our articles of incorporation and bylaws, and the laws of Michigan, include provisions which are designed to provide our Board of Directors with time to consider whether a hostile takeover offer is in our best interest and the best interests of our shareholders. These provisions could discourage potential acquisition proposals and could delay or prevent a change in control. The provisions also could diminish the opportunities for a holder of our common stock to participate in tender offers, including tender offers at a price above the then-current price for our common stock. These provisions could also prevent transactions in which our shareholders might otherwise receive a premium for their shares over then current market prices, and may limit the ability of our shareholders to approve transactions that they may deem to be in their best interests.

          The Michigan Business Corporation Act contains provisions intended to protect shareholders and prohibit or discourage certain types of hostile takeover activities. In addition to these provisions and the provisions of our articles of incorporation and by-laws, Federal law requires the Federal Reserve Board's approval prior to acquisition of "control" of a bank holding company. All of these provisions may have the effect of delaying or preventing a change in control at the company level without action by our shareholders, and therefore, could adversely affect the price of our common stock.

The Company will retain broad discretion in using the net proceeds from the offerings, and might not use the proceeds effectively.

          We intend to use a portion of the net proceeds of the offerings to contribute to the capital of the Bank to increase the Bank's capital and regulatory capital ratios and for general corporate purposes, including funding organic loan growth and long-term strategic opportunities. However, the Company has not designated the amount of net proceeds it will use for any particular purpose and the Company's management will retain broad discretion to allocate the net proceeds of the offerings. The net proceeds may be applied in ways with which some investors in the offerings may not agree. Moreover, the Company's management may use the proceeds for corporate purposes that may not increase our market value or make the Company more profitable. In addition, it may take the Company some time to effectively deploy the proceeds from the offerings. Until the proceeds are effectively deployed, the Company's return on equity and earnings per share may be negatively impacted.

TABLE OF CONTENTS

If, as a result of the offerings or otherwise, an entity holds as little as a 5% interest in our outstanding securities, that entity could, under certain circumstances, be subject to regulation as a "bank holding company."

          Any entity, including a "group" composed of natural persons, owning or controlling with the power to vote 25% or more of our outstanding securities, or 5% or more if the holder otherwise exercises a "controlling influence" over us, may be subject to regulation as a "bank holding company" in accordance with the Bank Holding Company Act of 1956, as amended (the "BHC Act"). In addition, any bank holding company or foreign bank with a U.S. presence may be required to obtain the approval of the Federal Reserve Board under the BHC Act to acquire or retain 5% or more of our outstanding securities. Becoming a bank holding company imposes statutory and regulatory restrictions and obligations, such as providing managerial and financial strength for its bank subsidiaries. Regulation as a bank holding company could require the holder to divest all or a portion of the holder's investment in our securities or those nonbanking investments that may be deemed impermissible or incompatible with bank holding company status, such as a material investment in a company unrelated to banking.

Any person not defined as a company by the BHC Act may be required to obtain the approval of the Federal Reserve Board under the Change in Bank Control Act of 1978, as amended, to acquire or retain 10% or more of our outstanding securities.

          Any person not otherwise defined as a company by the BHC Act and its implementing regulations may be required to obtain the approval of the Federal Reserve Board under the Change in Bank Control Act of 1978, as amended, to acquire or retain 10% or more of our outstanding securities. Applying to obtain this approval could result in a person incurring substantial costs and time delays. There can be no assurance that regulatory approval will be obtained.

FORWARD-LOOKING STATEMENTS

          This prospectus contains forward-looking statements that are based on management's beliefs, assumptions, current expectations, estimates and projections about the financial services industry, the economy, and Macatawa Bank Corporation. Forward-looking statements are identifiable by words or phrases such as "outlook" or "strategy," that an event or trend "may," "should," "will," "is likely," or is "probable" to occur or "continue" or "is scheduled" or "on track" or that the Company or its management "anticipates," "believes," "estimates," "plans," "forecasts," "intends," "predicts," "projects," or "expects" a particular result, or is "confident," "optimistic" or has an "opinion" that an event will occur, or other words or phrases such as "ongoing," "future," or "tend" and variations of such words and similar expressions. Such statements are based upon current beliefs and expectations and involve substantial risks and uncertainties which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These statements include, among others, statements related to real estate valuation, trends in credit quality metrics, economic and employment trends and projections, future levels of nonperforming loans, future levels of loan charge-offs, future levels of provisions for loan losses, the rate of asset dispositions, future capital levels, capital raising activities (including the successful completion of the offerings), dividends, future growth and funding sources, future liquidity levels, future profitability levels, our ability to comply with our Consent Order and Written Agreement, and the effects on earnings of changes in interest rates and the future level of other revenue sources. All of the information concerning interest rate sensitivity is forward-looking. All statements with references to future time periods are forward-looking.

          Management's determination of the provision and allowance for loan losses, the appropriate carrying value of intangible assets (including goodwill, mortgage servicing rights and tax deferred assets), other real estate owned and the fair value of investment securities (including whether any impairment on any investment security is temporary or other-than-temporary and the amount of any impairment) involves judgments that are inherently forward-looking. There can be no assurance that future loan losses will be limited to the amounts estimated. Our ability to fully comply with all of the provisions of our Consent Order and Written Agreement, improve regulatory capital ratios, raise additional capital, sell other real estate owned at its carrying value or at all, successfully implement new programs and initiatives, increase efficiencies, realize our deferred tax benefits, address regulatory issues, respond to declines in collateral values and credit quality, and improve profitability is not entirely within our control and is not assured. The future effect of changes in the financial and credit markets and the national and regional economy on the banking industry, generally, and on Macatawa Bank Corporation, specifically, are also inherently uncertain. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions ("risk factors") that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence. Therefore, actual results and outcomes may materially differ from what may be expressed or forecasted in such forward-looking statements. Macatawa Bank Corporation undertakes no obligation to update, clarify or revise forward-looking statements to reflect developments that occur or information obtained after the date of this prospectus.

          Risk factors include, but are not limited to, the risk factors described under "Risk Factors" beginning on page 23 of this prospectus and in "Item 1A - Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2010. These and other factors are representative of the risk factors that may emerge and could cause a difference between an ultimate outcome and a preceding forward-looking statement.

TABLE OF CONTENTS

USE OF PROCEEDS

          We estimate the net proceeds from the offerings, after estimated expenses, will be approximately $40.3 million. We intend to use a portion of the net proceeds of the offerings to contribute to the capital of the Bank to increase the Bank's capital and regulatory capital ratios. As of March 31, 2011, the Bank needed a capital injection of approximately $14.0 million to comply with the Tier 1 Leverage Capital Ratio requirement and needed a capital injection of approximately $7.1 million to comply with the Total Risk Based Capital Ratio requirement of the Consent Order. We intend to retain a portion of the net proceeds at the Company to pay a portion of the Company's direct operating expenses while the Company is unable to fund those expenses with dividends from the Bank. Assuming all of the shares in the offerings are sold, the Company intends to contribute $30.0 million of the net proceeds from the offerings to the Bank. There is no assurance as to any particular level of proceeds from the offerings.

          Funds contributed to the Bank will be used by the Bank for general operating purposes which may include, among others, funding of loans, investment in securities, and payment of expenses. The proceeds of the offerings which are not contributed to the Bank will be used by the Company for general corporate purposes which may include, among others, payment of expenses, payment of interest on subordinated notes and trust preferred securities, and pursuing strategic opportunities which may be presented to the Company in the future.

          In addition to the offerings, we are pursuing other strategies to comply with the capital requirements of the Consent Order. These include reducing operating costs, shrinking assets of the Bank without weakening its liquidity position, and preserving capital through suspension of dividends. Following is more information regarding these other strategies:

          There is no assurance that the offerings and these or other strategies to comply with the capital requirements of the Consent Order will be successful. See "Risk Factors."

CAPITALIZATION

          The following table sets forth our consolidated capitalization as of March 31, 2011 and our pro forma consolidated capitalization after giving effect to the receipt of net proceeds from the offerings, assuming in the alternative that the maximum amount of the offered shares are sold in the offerings (referred to below as the "100% participation scenario"), and that half of the offered shares are sold in the offerings (referred to below as the "50% participation scenario"). We are unable to predict the actual level of participation in the offerings. There is no assurance that we will achieve even the 50% participation scenario.

          The following unaudited information should be read in conjunction with our unaudited consolidated financial statements for the three months ended March 31, 2011, and related notes, included in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2011, and our audited consolidated financial statements for the year ended December 31, 2010, and related notes, included in our Annual Report on Form 10-K for the year ended December 31, 2010, which reports are incorporated by reference into this prospectus.
