--------------------------------------------------------------------------------

WHEREAS, Employee desires to enter into the New Employment Agreement and
continue to be eligible to receive Bonus Compensation and Equity Awards.
NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Employee agrees as follows:
1.    NON-USE OF EMPLOYER'S PROPERTY
All notes, reports, plans, published memoranda or other documents (in tangible
or electronic form) created, developed, generated or acquired by Employee, or to
which Employee otherwise has access, during the course of employment with
Employer, concerning or related to Employer’s business, whether or not
containing or relating to Confidential Information (as defined below), and all
tangible personal property of Employer entrusted to Employee or in Employee’s
direct or indirect possession or control, are solely the property of Employer,
and will be promptly delivered to Employer and not thereafter used by Employee
upon termination of Employee’s employment for any reason or no reason.
2.    NON-DISCLOSURE OF EMPLOYER'S CONFIDENTIAL INFORMATION
2.1    Confidential Information.  For purposes of this Agreement, “Confidential
Information” means any and all trade secrets and other confidential, proprietary
and/or non-public information of Employer, whether in tangible or electronic
form, that Employee creates, develops, generates or acquires, or to which
Employee otherwise has access, during the course of employment with Employer and
that Employer designates or treats as confidential through its policies,
practices or procedures. Confidential Information shall include, but is not
limited to, financial information and data; business and marketing plans,
practices and strategies; proprietary computer programs and other methods of
operation, techniques, systems and processes; intellectual property and other
research and development; statistical data and analyses; information concerning
Employer’s planned or pending investment products, acquisitions or divestitures;
personnel information, including the identity of officers and employees of
Employer, their responsibilities, competence, abilities and compensation;
financial, accounting and similar records of Employer and/or any fund or account
managed by Employer; current and prospective customer lists and information on
customers and prospective customers and their officers and other employees;
customer financial statements, investment objectives, the nature of their
investment portfolios and contractual agreements with Employer, and other
personal customer information; and other information received by Employer from
third parties in confidence or pursuant to a duty of confidentiality.
Notwithstanding the foregoing, Confidential Information shall not include
information which is in or hereafter enters the public domain through no fault
of Employee and without breach of any duty of confidentiality; information known
to Employee prior to first receipt of or access to such information in the
course of employment; or information rightfully received by Employee outside the
scope of employment from a third party who does not owe Employer a duty of
confidentiality with respect to such information.
2.2    Disclosure or Use.  Employee acknowledges and understands that Employer
has spent extensive time, effort and resources developing Confidential
Information and that, solely as a result

--------------------------------------------------------------------------------

of Employee’s employment with Employer, Employee has had and will continue to
have access to such Confidential Information. Employee further acknowledges and
understands that Employer has taken reasonable measures to protect and maintain
the secrecy of its Confidential Information. Accordingly, during the term of
Employee’s employment and thereafter, Employee agrees not to use or disclose any
Confidential Information except in furtherance of Employee’s duties for Employer
in the ordinary course of business and to otherwise comply with all policies of
Employer relating to the use and disclosure of Confidential Information. Upon
termination of employment with Employer for any reason or no reason, Employee
shall not, directly or indirectly, disclose, publish, communicate or use on
Employee’s behalf or another’s behalf, any Confidential Information.
2.3    Permitted Disclosure or Use.  To the extent applicable law requires a
finite duration, the foregoing restrictions on the disclosure or use of
Confidential Information shall apply for a period of five (5) years following
termination of Employee’s employment for any reason or no reason, unless such
information qualifies as a trade secret under applicable state or federal law or
Third Party Confidential Information, in which case the foregoing restrictions
shall continue for so long as the trade secrets remain secret and Employer
remains obligated to protect the Third-Party Confidential Information.
“Third-Party Confidential Information” means confidential and proprietary or
private information received by Employer from customers or other third-party
individuals or business entities in trust and confidence or pursuant to a duty
of confidentiality. If Employee is requested or becomes legally compelled to
make any disclosure that is otherwise prohibited by this Agreement, Employee
shall promptly notify Employer no later than fourteen (14) days prior to such
disclosure so that Employer may seek a protective order or other appropriate
relief if Employer deems such protection or remedy necessary. Subject to the
foregoing, Employee may furnish only that portion of the Confidential
Information that Employee is legally compelled or required by law to disclose.
However, nothing in this Agreement, any other agreement between Employee and
Employer or in any Employer policy applicable to Employee shall preclude
Employee from providing a federal or state governmental, regulatory or
administrative agency truthful information concerning a suspected violation of
the law without disclosure (in advance or otherwise) to Employer.
Notwithstanding anything herein to the contrary, under the Federal Defend Trade
Secrets Act of 2016, an individual may not be held criminally or civilly liable
under any Federal or State trade secret law for the disclosure of a trade secret
that (a) is made (1) in confidence to a Federal, State or local government
official, either directly or indirectly, or to an attorney; and (2) solely for
the purpose of reporting or investigating a suspected violation of law; or
(b) is made in a complaint or other document filed in a lawsuit or other
proceeding, if such filing is made under seal. An individual who files a lawsuit
for retaliation by an employer for reporting a suspected violation of law may
disclose the trade secret to the attorney of the individual and use the trade
secret information in the court proceeding if the individual files any document
containing the trade secret under seal and does not disclose the trade secret
except pursuant to court order. Nothing herein is intended, or should be
construed, to affect the immunities created by the Defend Trade Secrets Act of
2016.

--------------------------------------------------------------------------------

3.    NON-COMPETITION WITH THE EMPLOYEE
3.1    Non-Competition. Employee agrees that during the period of employment and
for the period ending one year after the last day of Employee’s employment with
Employer (the “Date of Termination”), Employee will not in any manner, directly
or indirectly (whether as an officer, director, employee, investor, consultant,
independent contractor or otherwise), engage or be engaged in, provide services
to, for or on behalf of, or assist any other person, firm, corporation or
enterprise in engaging or being engaged in, any business providing banking
products or services competitive with any banking product or service provided by
Employer in any geographic region or territory in which Employer maintains a
material banking or financial services business which provides such banking
products and services. In the event the Date of Termination occurs on or after
the date of a Change in Control (as defined in the New Employment Agreement),
the one year period set forth in the preceding sentence shall be extended to two
years.
3.2    Banking Products or Services. For purposes of this Section 3, “banking
products or services” are products or services of the type described in Item 1
of the most recent Form 10‑K filed by FMBI with the Securities and Exchange
Commission, which products and services shall include, but are not limited to,
deposit products and services, corporate and consumer lending products and
services, treasury management products and services and wealth management
products and services.
3.4    Geographic Territory. Employee acknowledges and agrees that the
geographic region or territory in which Employer maintains a material banking or
financial services business providing banking products or services is comprised
of the following areas: (a) the area within fifty (50) miles of Employer’s
corporate headquarters in Chicago, Illinois; and (b) the area within thirty
(30) miles of any branch or office of the Employer which, as of the Date of
Termination, was staffed with at least fifteen (15) employees engaged in banking
or other financial services.
3.5    Exception for Ownership of Publicly Traded Stock. Nothing herein shall
prohibit Employee from being a passive owner of not more than 1% of the
outstanding equity interest in any entity that is publicly traded, so long as
the Employee has no active participation in the business of such entity.
4.    NON-INTERFERENCE WITH EMPLOYER’S CUSTOMERS
Employee acknowledges and understands that Employer has spent extensive time,
effort and resources developing and maintaining personal contacts and
relationships with customers and that, solely as a result of his or her
employment with Employer, Employee has had and will continue to have direct
contact and dealings with, management or supervisory responsibility for, or
access to Confidential Information about, such customers. Therefore, during the
period of Employee’s employment with Employer and thereafter, without
interruption, for the period ending eighteen (18) months after the Date of
Termination (or two (2) years if the Date of Termination occurs on or after the
date of a Change in Control, as defined in the New Employment Agreement),
Employee agrees not to, directly or indirectly, for Employee’s own account or as
an agent, officer, director, owner, partner or consultant of any corporation,
firm, partnership, joint venture, syndicate, sole proprietorship or other
entity, solicit, call upon, contact, contract with, sell to or perform services

--------------------------------------------------------------------------------

for, or attempt to solicit, call upon, contact, contract with, sell to or
perform services for, any customers of Employer for the purpose of providing to
such customer banking products or services of any kind that are offered or
provided by Employer, or to assist any person, business or entity to do so. For
purposes of this provision, the term “customer” means any business, entity or
person which is or was a customer of Employer at any time during the period of
Employee’s employment with Employer and with respect to which Employee had
contact or supervisory responsibility in course of conducting business for
Employer or about whom Employee had access to and used Confidential Information,
other than any customer which has ceased to do business with Employer at least
six (6) months prior to the last day of Employee’s employment without any
inducement, encouragement or involvement of Employee.
5.    NON-SOLICITATION AND NO-HIRE OF EMPLOYER’S EMPLOYEES
Employee acknowledges and understands that Employer has spent extensive time,
effort and resources training and maintaining a stable workforce and that,
solely as a result of Employee’s employment with Employer, Employee has had and
will continue to have direct contact and dealings with employees of Employer.
Therefore, during the period of Employee’s employment with Employer and
thereafter, without interruption, for the period ending 18 months after the Date
of Termination (two years if the Date of Termination occurs on or after the date
of a Change in Control, as defined in the New Employment Agreement), Employee
agrees not to, directly or indirectly, for Employee’s own account or as an
agent, officer, director, owner, partner, or consultant of any corporation,
firm, partnership, joint venture, syndicate, sole proprietorship or other
entity: (a) solicit, induce, recruit or encourage, or attempt to solicit,
induce, recruit or encourage, any employee of Employer to leave the employ of
Employer, or to assist any other person, business or entity to do so; or
(b) hire or attempt to hire any employee of Employer, or assist any other
person, business or entity to do so. For purposes of this provision, the term
“employee” means any person who is or was an employee of Employer during the
period of Employee’s employment with Employer and with respect to which Employee
had contact or supervisory responsibility in the course of conducting business
for Employer or about whom Employee had access to and used Confidential
Information related to their performance or advancement potential, other than a
former employee who has not been employed by Employer for a period of at least
six (6) months prior to the last day of Employee’s employment without any
inducement, encouragement or involvement of Employee.
6.    NON-DISPARAGEMENT OF EMPLOYER
Employee acknowledges and understands that Employer’s good name and its goodwill
are extremely valuable and the result of the expenditure of substantial time,
effort and resources by Employer. Therefore, during the period of Employee’s
employment with Employer and thereafter, without interruption, for the period
ending two years after the Date of Termination, Employee agrees not to make, or
cause to be made, any statement or disclosure that disparages Employer, or any
director, officer or employee of Employer, or assist any other person, business
or entity to do so.

--------------------------------------------------------------------------------

7.    GENERAL PROVISIONS
7.1    No Inducements.  In agreeing to the protective covenants set forth herein

representations of Employer, or its officers or directors, other than the terms
and conditions specifically set forth in this Agreement.

Employer. Employee also acknowledges that, while Employee is eligible to earn
compensation, and to receive Bonus Compensation or Equity Awards, the payment of
such compensation and/or granting of any such Bonus Compensation and Equity
Awards, as the case may be, is subject to the terms and conditions of such Bonus

7.5    Equitable Relief.  Employee acknowledges that Employer will suffer
irreparable harm if Employee breaches or threatens to breach this Agreement and
that, in the event of Employee’s actual or threatened breach of this Agreement,
Employer will have no adequate remedy at law. Accordingly, Employee agrees that,
in addition to any other remedies at law or in equity available to Employer for

to specific performance or injunctive relief against Employee to prevent any
such actual or threatened breach without the necessity of posting a bond or
other security.

by the parties hereto and, in the case of Employer, such waiver, modification or
discharge has been authorized or approved by the Board of Directors or an
authorized officer of Employer. Any waiver of any breach of any kind or
character whatsoever shall not be construed as a continuing waiver of, or
consent to, any subsequent breach of this Agreement.
7.10    Headings.  The headings used in this Agreement are for convenience only
and are not part of its operative language. They shall not be used to affect the
construction of any provisions hereof.
7.11    Severability.  The provisions of this Agreement are severable and should
any provision hereof be void, voidable or unenforceable under applicable law,
such void, voidable or unenforceable provision shall not affect or invalidate
any other provision of this Agreement, which shall continue to govern the
relative rights and duties of the parties hereto as though the void, voidable or
unenforceable provision were not a part hereof.
7.12    “Blue Pencil Provision”.  In the event that any provision, or part
thereof, shall be declared by a court to exceed the maximum time period or scope
that the court deems to be enforceable, then the parties hereto expressly
authorize the court to modify such provision, or part thereof, so that it may be
enforced to the fullest extent permitted by law.
7.13    Other Agreements.  This Agreement is in addition to and supplements any
other written agreements between the parties that contain restrictive covenant
obligations. Notwithstanding the foregoing, this Agreement supersedes and
cancels the Confidentiality and Restrictive Covenants Agreement dated
