MIDSOUTH BANCORP, INC.
INCENTIVE STOCK OPTION AGREEMENT

THIS INCENTIVE STOCK OPTION AGREEMENT (“Agreement”), dated as of
_________________ (the “Date of Grant”), between MidSouth Bancorp, Inc.
(“MidSouth”) and _________________ (the “Optionee”).

1.           Grant of Incentive Stock Option.  MidSouth, through the
Compensation Committee of its Board of Directors (“Committee”), hereby grants to
the Optionee, as of the Date of Grant, an option to purchase up to ______ shares
of Common Stock for $_____ per share.  The Option is intended to be, and shall
be treated as, an “incentive stock option” under Sections 421 and 422 of the
Internal Revenue Code of 1986, as amended (the “Code").

2.           Term and Exercise.  Unless a shorter period is provided by the
Committee or as otherwise provided herein or in the MidSouth 2007 Omnibus
Incentive Compensation Plan (the "Plan"), during the first year from the Date of
Grant, the Option may not be exercised; during the second year, the Option may
be exercised with respect to up to 20% of the total number of shares covered;
during the third year, up to 40% of the shares; during the fourth year, up to
60% of the shares; during the fifth year, up to 80% of the shares; and during
the sixth and each subsequent year until ten years from the Date of Grant, up to
100% of the total number of shares covered.  Notwithstanding the foregoing, the
Option shall become immediately exercisable in full upon Optionee’s death,
disability or retirement while employed by MidSouth or any subsidiary
thereof.  No fractional shares shall be issued as a result of the exercise of
this Option.  No Option shall be exercisable after ten years from the Date of
Grant.

3.           Termination of Option.  Upon the tenth anniversary of the Date of
Grant this Option shall terminate, regardless of the extent to which it is
exercisable before that date and regardless of the next sentence.  In addition,
upon termination of the Optionee’s employment, the Option, to the extent not
previously exercised, shall terminate 90 days from such termination, except that
upon termination of the Optionee’s employment by reason of death, disability or
retirement, it may be exercised within six months from the date thereof by the
Optionee or the executor or administrator of the deceased Optionee’s estate or
by a person receiving the Option by will or under the laws of descent and
distribution of the state in which the Optionee resided.  Notwithstanding any
other provisions hereof, if the Optionee shall (i) commit any act of malfeasance
or wrongdoing materially affecting MidSouth or any subsidiary thereof, or (ii)
compete with MidSouth or any subsidiary thereof, or (iii) engage in conduct that
would warrant the Optionee’s discharge for cause (excluding general
dissatisfaction with the performance of the Optionee’s duties, but including any
act of disloyalty or any conduct clearly tending to bring discredit upon
MidSouth or any subsidiary thereof ), then any unexercised portion of the Option
shall terminate and be void (whether or not the option is exercisable at such
time).

4.           Exercise of Option.  The Optionee may exercise the Option with
respect to all or any part of the number of Option shares then exercisable in
the manner specified in Section 6.5 of the Plan.  On the exercise date or as
soon thereafter as is reasonable practicable, MidSouth shall cause to be
delivered to the Optionee, a certificate or certificates for the Option shares
then being purchased upon full payment for such Option shares, subject to the
condition of Section 11.4 of the Plan.  If the Optionee fails to pay for any of
the Option shares specified in the notice of exercise, or fails to accept
delivery thereof, the Optionee’s right to purchase such shares may be terminated
by MidSouth.  The date specified in the Optionee’s notice of exercise as the
date of exercise shall be deemed to be the date of exercise of the Option,
provided that payment in full for the Option shares to be purchased upon such
exercise shall have been received by such date.

5.           No rights as a Stockholder.  Neither the Optionee nor any personal
representative shall be, or shall have any of the rights and privileges of, a
stockholder of MidSouth with respect to any shares purchasable upon the exercise
of this Option, in whole or in part, prior to the issuance of certificates for
shares of Common Stock to such person.

6.           Transferability.  No Option shall be transferable except as
specified in Section 11.2 of the Plan. Only the Optionee may exercise this
Option during the Optionee’s lifetime.

7.           No Rights of Employment.  Neither the granting of this Option nor
its exercise shall be construed as granting to the Optionee any right with
respect to continuance of employment with MidSouth or any subsidiary
thereof.  Except as may otherwise be limited by a written agreement between
MidSouth and the Optionee, the right of MidSouth or any subsidiary thereof  to
terminate at will the Optionee’s employment at any time (whether by dismissal,
discharge, retirement or otherwise) is specifically reserved by MidSouth or any
subsidiary thereof.

8.           Amendment of Option.  The Committee may, without further action by
the stockholders and without the consent of or further consideration from the
Optionee, amend, condition or modify this Option in respect to changes in
securities or other laws or rules, regulations or regulatory interpretations
thereof applicable to the Option or to comply with stock exchange rules or
requirements.  The Committee may amend this Option otherwise with the written
consent of the Optionee.

9.           Notice.  Any notice to MidSouth hereunder shall be addressed to it
in care of its secretary at 102 Versailles Boulevard, Lafayette, Louisiana
70501, any notice to the Optionee shall be addressed to the Optionee at the
current address shown on the payroll records of MidSouth.  Any notice shall be
deemed to be duly given if and when properly addressed and posted by registered
or certified mail, postage prepaid.

10.           Incorporation of Plan by Reference.  The Option is granted
pursuant to the terms of the Plan, which are incorporated herein by reference,
and the Option shall in all respects be interpreted in accordance with the
Plan.  The Committee shall interpret and construe the Plan and this Agreement,
and its interpretations and determinations shall be conclusive and binding on
the parties and any other person claiming an interest hereunder, with respect to
any issue arising hereunder or thereunder. All terms used herein and not
otherwise defined shall have the meanings assigned to them in the Plan.
