HARRINGTON (“Employee”).

RECITALS

A.Pursuant to Section 6.14 of that certain Agreement and Plan of Merger dated September 20, 2006 between First Busey and Main Street Trust, Inc., an Illinois corporation (“Main Street”), (the “Merger Agreement”), First Busey is entering into this Agreement with the Employee.

B.Employee will serve as the Chief Financial Officer and Executive Vice President of First Busey as of the Effective Date.

C.First Busey and Employee have made commitments to each other on a variety of important issues concerning her employment, including the performance that will be expected of her, the compensation that she will be paid, how long and under what circumstances she will remain employed, and the financial details relating to any decision that either Employee or First Busey might ever make to terminate this Agreement.

D.First Busey and Employee believe that the commitments they have made to each other should be memorialized in writing, and that is the purpose of this Agreement.

THEREFORE, First Busey and Employee agree as follows:

AGREEMENTS

1.Term and Automatic Renewal.  The term of this Agreement and Employee’s employment hereunder shall commence as of the Effective Date hereof and continue until December 31, 2007. On January 1, 2008 and each January 1 thereafter this Agreement and the term of Employee’s employment hereunder will automatically renew for one (1) additional year unless this Agreement and Employee’s employment hereunder are terminated in accordance with the provisions of Section 4.

2.Employment.  First Busey and Employee each confirm that Employee will be employed as the Chief Financial Officer and Executive Vice President of First Busey as of the Effective Date in accordance with the terms of this Agreement.

(a)Positions.  Subject to the terms of this Agreement, First Busey will employ Employee as the Chief Financial Officer and Executive Vice President of First Busey.

(b)Duties.  Employee’s duties, authority and responsibilities as the Chief Financial Officer and Executive Vice President of First Busey include and will continue to include all duties, authority and responsibilities customarily held by the Chief Financial Officer and Executive Vice President of bank holding companies, subject always to the charter and bylaw provisions and the policies of First Busey and the directions of its board of directors (the “Board”), and where applicable, of any of its subsidiaries.

(c)Care and Loyalty.  Employee will devote her best efforts and full business time, energy, skills and attention to the business and affairs of First Busey, and will faithfully and loyally discharge her duties to First Busey.

3.Compensation.  First Busey will compensate Employee for her services as follows during the term of this Agreement and her employment hereunder:

(a)Base Compensation.  Employee will receive an annual base salary of $145,000, subject to any increase made by First Busey as of January 1, 2007, through December 31, 2007.  Prior to January 1, 2008, the Board will review Employee’s base salary to determine whether it should be maintained at its then existing level or increased effective as of January 1, 2008.  Following the adjustment, if any, made as of January 1, 2008 the Board will review Employee’s base salary annually during the term of this Agreement to determine whether it should be maintained at its then existing level or increased; provided that Employee’s annual base salary after any such adjustment will not be lower than her base salary for the immediately preceding year.

(b)Performance Bonus.  First Busey will pay Employee a performance bonus at the end of each year.  Employee and the Board will establish mutually agreed upon performance criteria and will also establish the amount of the maximum bonus that Employee will receive for each year if she meets the performance criteria.  Nothing in this Agreement will preclude the Board from awarding Employee an annual bonus in any year that exceeds the maximum bonus amount established for that year.

(c)Profit Sharing Benefit.  Employee will receive an annual profit sharing benefit of up to 10% of the combined amount of her annual base salary and performance bonus.  The Board will decide the exact amount of this benefit annually within that range.  First Busey will contribute this benefit to First Busey’s tax-qualified retirement plans and/or its non tax-qualified deferred compensation programs for the account of Employee.  All such benefit payments will be determined and governed by the terms of the particular plan or program.

(d)Car Allowance.  First Busey will pay Employee a car allowance of $600 per month through December 31, 2007.  Commencing as of January 1, 2008, the car allowance will be subject to annual review by the Board and will be maintained or increased as the Board deems appropriate.  First Busey will also insure

2

Employee’s car at First Busey’s expense under First Busey’s general corporate automobile insurance program.

(e)Club Membership.  First Busey expects Employee to entertain clients and prospective clients of First Busey and Busey Bank at the country club to which she belongs, and thus will reimburse Employee’s dues for her country club membership in an amount not to exceed $4,800 per year through December 31, 2007.  Commencing as of January 1, 2008, this allowance will be subject to annual review by the Board and may be maintained or increased as the Board deems appropriate.

(f)Reimbursement of Expenses.  First Busey will reimburse Employee for all travel, entertainment and other out-of-pocket expenses that she reasonably and necessarily incurs in the performance of her duties.  Employee will document these expenses to the extent necessary to comply with all applicable laws and internal policies.

(g)Other Benefits.  Employee will be entitled to participate in all plans and benefits that are now or later made available by First Busey to its senior executives generally.

(h)Vacations.  Employee will receive at least twenty (20) days of paid vacation annually, subject to First Busey’s general vacation policy.

(i)Withholding.  Employee acknowledges that First Busey may withhold any applicable federal, state or local withholding or other taxes from payments that become due to her.

(j)Allocations.  Employee and First Busey intend that Employee will be a dual employee of First Busey and one or more of its subsidiaries, and that Employee will be devoting substantial time and attention to the affairs of the subsidiaries.  First Busey may allocate to Busey Bank, or any other of First Busey’s subsidiaries any portion of Employee’s salary, cash bonus and other compensation and benefits that First Busey and Busey Bank or any other of First Busey’s subsidiaries deem to be a lawful and appropriate allocation, but no such allocation will relieve First Busey of any of its obligations to Employee under this Agreement.

4.Term and Termination.

(a)Termination Without Cause.  Either First Busey or Employee may terminate this Agreement and Employee’s employment hereunder for any reason by delivering written notice of termination to the other party no less than ninety (90) days before the effective date of termination, which date will be specified in the notice of termination.

(b)Termination for Cause.  First Busey may terminate this Agreement and Employee’s employment hereunder for Cause by delivering written notice of

3

termination to Employee no less than thirty (30) days before the effective date of termination.  “Cause” for termination will exist if: (i) Employee engages in one or more unsafe and unsound banking practices or violations of a law, regulation or written policy of First Busey or any of its subsidiaries, which individually or together have or threaten to have a material and adverse effect on the financial condition of First Busey taken as a whole; (ii) Employee engages in a deliberate act of dishonesty involving the affairs of First Busey or any of its subsidiaries or commits a wilful and material violation of her fiduciary duties to First Busey or any of its subsidiaries; (iii) Employee is removed or suspended from banking pursuant to Section 8(e) of the Federal Deposit Insurance Act or any other applicable State or Federal law; or (iv) Employee commits a material breach of her obligations under this Agreement and fails to cure the breach within thirty (30) days after First Busey gives Employee written notice of the breach.  First Busey will specify the factual and legal basis for its belief that Cause for termination exists in the notice of termination.  If Employee so requests, First Busey will provide Employee with a reasonable opportunity prior to the effective date of termination to cure any correctable violation of law, regulation, policy or duty that First Busey has specified in the notice of termination, and to appear before the Board and any applicable governmental authority to dispute any facts that are alleged to constitute Cause for termination.

(c)Constructive Discharge.  If Employee is ever Constructively Discharged, she may terminate this Agreement and her employment hereunder by delivering written notice to First Busey no later than thirty (30) days before the effective date of termination.  “Constructive Discharge” means the occurrence of any one or more of the following: (i) Employee is not reelected to or is removed as Chief Financial Officer and Executive Vice President of First Busey; or (ii) First Busey fails to vest Employee with or removes from her the duties, responsibilities, authority or resources that she reasonably needs to competently perform her duties as the Chief Financial Officer and Executive Vice President of First Busey; or (iii) First Busey notifies Employee pursuant to Section 4(a) that it is terminating this Agreement; or (iv) First Busey changes the primary location of Employee’s employment to a place that is more than fifty (50) miles from Champaign, Illinois; or (v) First Busey otherwise commits a material breach of its obligations under this Agreement and fails to cure the breach within thirty (30) days after Employee gives First Busey written notice of the breach.

(d)Termination upon Change of Control.  Employee may terminate this Agreement and her employment hereunder for any reason within one (1) year after a Change of Control occurs by delivering written notice of termination to First Busey or its successor no less than thirty (30) days before the effective date of termination.  After one (1) year following the Change of Control, Employee may terminate this Agreement and her employment hereunder only in accordance with Section 4(a) or (c).

(i)A “Change of Control” will be deemed to have occurred if: a) any person (as such term is defined in Section 13(d) or 14(d) of the Securities

4

Exchange Act of 1934, as amended (the “1934 Act”)) acquires beneficial ownership (within the meaning of Rule 13d-3 promulgated under the 1934 Act) of 33% or more of the combined voting power of the then outstanding voting securities; or b) the individuals who were members of the Board on the Effective Date (the “Current Board Members”) cease for any reason to constitute a majority of the Board of First Busey or its successor; however, if the election or the nomination for election of any new director of First Busey or its successor is approved by a vote of a majority of the individuals who are Current Board Members, such new director shall, for the purposes of this Section 4(d)(i), be considered a Current Board Member; or c) First Busey’s stockholders approve (1) a merger or consolidation of First Busey or Busey Bank and the stockholders of First Busey immediately before such merger or consolidation do not, as a result of such merger or consolidation, own, directly or indirectly, more than 67% of the combined voting power of the then outstanding voting securities of the entity resulting from such merger or consolidation in substantially the same proportion as their ownership of the combined voting power of the outstanding securities of First Busey immediately before such merger or consolidation; or (2) a complete liquidation or dissolution or an agreement for the sale or other disposition of all or substantially all of the assets of First Busey or Busey Bank.

(ii)Notwithstanding and in lieu of Section 4(d)(i), a Change of Control will not be deemed to have occurred: a) solely because 33% or more of the combined voting power of the then outstanding voting securities of First Busey are acquired by (1) a trustee or other fiduciary holding securities under one or more employee benefit plans maintained for employees of First Busey or Busey Bank, or (2) any person pursuant to the will or trust of any existing stockholder of First Busey, or who is a member of the immediate family of such stockholder, or (3) any corporation which, immediately prior to such acquisition, is owned directly or indirectly by the stockholders in the same proportion as their ownership of stock immediately prior to such acquisition; (b) if Employee agrees in writing to waive a particular Change of Control for the purposes of this Agreement or (c) upon the consummation of the transactions contemplated by the Merger Agreement.

(e)Termination upon Disability.  First Busey will not terminate this Agreement and Employee’s employment hereunder if Employee becomes disabled within the meaning of First Busey’s then current employee disability program or, at First Busey’s election, as determined by a physician selected by First Busey, unless as a result of such disability, Employee is unable to perform her duties with the requisite level of skill and competence for a period of six (6) consecutive months.  Thereafter, First Busey may terminate this Agreement in accordance with Section 4(a).

5

(f)Termination upon Death.  This Agreement will terminate if Employee dies during the term of this Agreement, effective on the date of her death.  Any payments that are owing to Employee under this Agreement or otherwise at the time of her death will be made to whomever Employee may designate in writing as her beneficiary, or absent such a designation, to the executor or administrator of her estate.

(g)Severance Benefits.  First Busey will pay severance benefits to Employee as follows:

(i)If this Agreement and Employee’s employment hereunder are terminated by First Busey without Cause pursuant to Section 4(a), or by reason of Employee’s Constructive Discharge pursuant to Section 4(c), or due to Employee’s disability or death pursuant to Section 4(e) or 4(f), First Busey will pay Employee an amount equal to the sum of her then applicable annual base salary, plus the amount of the most recent performance bonus that First Busey awarded to Employee pursuant to Section 3(b) (collectively, the “Severance Payment”).  If the effective date of termination occurs before the last day of the then current term, the Severance Payment will also include the value of the contributions that would have been made to Employee or for her benefit under all applicable retirement and other employee benefit plans had she remained in First Busey’s employ through the last day of the then current term.  First Busey will also continue to provide Employee and her dependents, at the expense of First Busey, with continuing coverage under all existing life, health and disability programs for a period of one (1) year following the effective date of termination.  In addition, if Employee is terminated without Cause pursuant to Section 4(a), or by reason of Employee’s Constructive Discharge pursuant to Section 4(c), or due to Employee’ s disability or death pursuant to Section 4(e) or 4(f), within the eighteen (18) month period immediately preceding a Change of Control, then upon the Change of Control, First Busey or its successor will pay Employee the difference between the amount paid pursuant to this Section 4(g)(i) and the amount which would have been paid pursuant to Section 4(g)(ii) had Employee’s employment not earlier terminated.

(ii)If within one (1) year after a Change of Control occurs this Agreement and Employee’s employment hereunder are terminated by Employee pursuant to Section 4(a), (c) or (d), or this Agreement and Employee’s employment hereunder are terminated by First Busey or its successor pursuant to Section 4(a) or (b) in other words, if terminated for any reason after Change in Control, including if fired for Cause, severance will be paid either within the eighteen (18) month period immediately preceding a Change of Control or at any time after a Change of Control occurs, then First Busey or its successor will pay Employee an amount equal to the greater of Three Hundred Thousand Dollars ($300,000) or two (2) times the Severance Payment.  In this event, First Busey or its successor will also continue to provide Employee and her dependents, at the expense of

6

First Busey or its successor, with continuing coverage under all existing life, health and disability programs for a period of three (3) years following the effective date of termination.

(iii)All payments that become due to Employee under this Section 4(g) will be made in equal monthly installments unless First Busey elects to make those payments in one (1) lump sum.  First Busey will be obligated to make all payments that become due to Employee under this Section 4(g) whether or not she obtains other employment following termination or takes steps to mitigate any damages that she claims to have sustained as a result of termination.  The payments and other benefits provided for in this Section 4(g) are intended to supplement any compensation or other benefits that have accrued or vested with respect to Employee or her account as of the effective date of termination.

(iv)First Busey and Employee intend that no portion of any payment under this Agreement, or payments to or for the benefit of Employee under any other agreement or plan, be deemed to be an “Excess Parachute Payment” as defined in Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), or its successors.  It is agreed that the present value of any payments to or for the benefit of Employee in the nature of compensation, as determined by the legal counsel or certified public accountants for First Busey in accordance with Section 280G(d)(4) of the Code, receipt of which is contingent on the Change of Control of First Busey, and to which Section 280G of the Code applies (in aggregate “Total Payments”), shall not exceed an amount equal to one dollar ($1.00) less than the maximum amount which First Busey may pay without loss of deduction under Section 280G(a) of the Code.

(v)First Busey may elect to defer any payments that may become due to Employee under this Section 4(g) if, at the time the payments become due, First Busey is not in compliance with any regulatory-mandated minimum capital requirements or if making the payments would cause First Busey’s capital to fall below such minimum capital requirements.  In this event, First Busey will resume making the payments as soon as it can do so without violating such minimum capital requirements.

5.Confidentiality.  Employee acknowledges that the nature of her employment will require that she produce and have access to records, data, trade secrets and information that are not available to the public regarding First Busey and its subsidiaries and affiliates (“Confidential Information”).  Employee will hold in confidence and not directly or indirectly disclose any Confidential Information to third parties unless disclosure becomes reasonably necessary in connection with Employee’s performance of her duties hereunder, or the Confidential Information lawfully becomes available to the public from other sources, or she is authorized in writing by First Busey to disclose it, or she is required to make disclosure by a law or pursuant to the authority of any administrative agency or judicial body.  All Confidential Information and all other records, files,

7

documents and other materials or copies thereof relating to First Busey’s business that Employee prepares or uses will always be the sole property of First Busey.  Employee will promptly return all originals and copies of such Confidential Information and other records, files, documents and other materials to First Busey if her employment with First Busey is terminated for any reason.

6.Non-Competition Covenant.

(a)Restrictive Covenant.  First Busey and Employee have jointly reviewed the customer lists and operations of First Busey and agree that First Busey’s primary service area for its lending and deposit activities encompasses a fifty (50) mile radius from First Busey’s main office.  Employee agrees that, for a period of one (1) year after the termination of this Agreement, she will not, without First Busey’s prior written consent, directly or indirectly Compete with First Busey for the purposes of Section 6(a):

(i)“Compete” means directly or indirectly owning, managing, operating or controlling a Competitor, or directly or indirectly serving as an employee, officer or director of or a consultant to a Competitor, or soliciting or inducing any employee or agent of First Busey to terminate employment with First Busey and become employed by a Competitor.

(ii)“Competitor” means any person, firm, partnership, Corporation, trust or other entity that owns, controls or is a bank, savings and loan association, credit union or similar financial institution (a “Financial Institution”) that is physically located and conducts substantial lending and deposit taking activities within a fifty (50) mile radius of First Busey’s main office.

(b)Successors.  In the event that a successor to First Busey or Busey Bank succeeds to or assumes First Busey’s rights and obligations under this Agreement, Section 6(a) will apply only to the primary service area of First Busey as it existed immediately before the succession or assumption occurred and will not apply to any of the successor’s other offices.

(c)Investment Exception.  Section 6(a) will not prohibit Employee from directly or indirectly owning or acquiring any capital stock or similar securities that are listed on a securities exchange or quoted on the National Association of Securities Dealers Automated Quotation System and do not represent more than 5% of the outstanding capital stock of any Financial Institution.

(d)Injunctive Relief.  Employee agrees that a violation of this Section 6 would result in direct, immediate and irreparable harm to First Busey, and in such event, agrees that First Busey, in addition to its other right and remedies, would be entitled to injunctive relief enforcing the terms and provisions of this Section 6.

(b)Advancement of Expenses.  In the event that Employee becomes a party, or is threatened to be made a party, to any pending, threatened or completed action, suit or proceeding for which First Busey or any of its subsidiaries is permitted or required to indemnify her under this Agreement, any applicable bylaw or charter provision of First Busey or any of its subsidiaries, any resolution of First Busey or any of its subsidiaries, or any applicable statute, First Busey will, to the fullest extent permitted by law, advance all Expenses incurred by Employee in connection with the investigation, defense, settlement, or appeal of any threatened, pending or completed action, suit or proceeding, subject to receipt by First Busey of a written undertaking from Employee to reimburse First Busey for all Expenses actually paid by First Busey to or on behalf of Employee in the event it shall be ultimately determined that First Busey or any of its subsidiaries cannot lawfully indemnify Employee for such Expenses, and to assign to First Busey all rights of Employee to indemnification under any policy of directors’ and officers’ liability insurance to the extent of the amount of Expenses actually paid by First Busey to or on behalf of Employee.

(c)Litigation.  Unless precluded by an actual or potential conflict of interest, First Busey will have the right to recommend counsel to Employee to represent her in connection with any claim covered by this Section 7.  Further, Employee’s choice of counsel, her decision to contest or settle any such claim, and the terms and amount of the settlement of any such claim will be subject to First Busey’s prior written approval.

8.General Provisions.

9

purchaser or acquiror of all or substantially all of the business, assets or liabilities of First Busey or Busey Bank, whether by transfer, purchase, merger, consolidation, stock acquisition or otherwise, to assume and agree in writing to perform this Agreement and First Busey’s obligations hereunder in the same manner and to the same extent as First Busey would have been required to perform them if no such transaction had occurred.

(b)Entire Agreement; Survival.  This Agreement constitutes the entire agreement between Employee and First Busey concerning the subject matter hereof, and supersedes all prior negotiations, undertakings, agreements and arrangements with respect thereto, whether written or oral.  The provisions of this Agreement will be regarded as divisible and separate; if any provision is ever declared invalid or unenforceable, the validity and enforceability of the remaining provisions will not be affected.  This Agreement may not be amended or modified except by a writing signed by Employee and First Busey, and except for the employment obligations set forth in Section 2, all rights and obligations of Employee and First Busey hereunder shall survive the termination of this Agreement.  If the Merger Agreement terminates in accordance with its terms, this Agreement shall terminate and be null and void.
