EXHIBIT 10.8
MANTECH INTERNATIONAL CORPORATION
STANDARD TERMS AND CONDITIONS FOR
RESTRICTED STOCK AWARDS
These Standard Terms and Conditions apply to any Restricted Shares granted under
the Management Incentive Plan of ManTech International Corporation (2011
Restatement) (the “Plan”), which are evidenced by a Term Sheet or an action of
the Committee that specifically refers to these Standard Terms and Conditions.
1.    Terms of Restricted Shares
ManTech International Corporation, a Delaware corporation (“ManTech”), has
granted to the Eligible Person named in the Term Sheet provided to such Eligible
Person (the “Term Sheet”) the number of Restricted Shares of ManTech’s Class A
Common Stock, $0.01 par value per share (the “Common Stock”), set forth in the
Term Sheet, subject to the restrictions and the other terms and conditions set
forth in the Term Sheet, these Standard Terms and Conditions, and the Plan (each
as amended from time to time).
2.    Vesting of Restricted Shares
The Restricted Shares shall be forfeitable and nontransferable until the
Restricted Shares become vested, as described in the Term Sheet. The vesting of
the Restricted Shares is subject to termination or acceleration as provided in
these Standard Terms and Conditions and the Plan. In addition to the vesting as
provided in the Term Sheet, the Restricted Shares will be subject to the
following provisions:
A.
Upon the date of a termination of employment with ManTech as a result of death
or disability, the Restricted Shares shall become fully vested.

B.
Upon the date of a termination of employment with ManTech for any reason other
than the death or disability, any Restricted Shares that are not yet vested as
of such termination date shall be forfeited back to ManTech, and the award shall
terminate as of such date

Once vested, the Restricted Shares shall be nonforfeitable and freely
transferable.
3.    Delivery of Restricted Shares
ManTech shall, as soon as administratively practicable after the Grant Date,
direct ManTech’s transfer agent for Common Stock to make a book entry record
reflecting issuance of the Restricted Shares, subject to the terms and
conditions of the Term Sheet, the Standard Terms and Conditions and the Plan.
ManTech shall record, or shall direct its transfer agent to record, ownership of
Restricted Shares so issued in the Eligible Person’s name (or, at the request of
such Eligible Person, in the Eligible Person’s and Eligible Persons’s spouse’s
names as community property or as joint tenants with right of survivorship). As
soon as practicable following the date on which the Restricted Shares become
nonforfeitable and fully transferable pursuant to Section 2 above, ManTech will
issue appropriate instructions to that effect to the transfer agent for Common
Stock.

Fractional shares may not be issued. ManTech shall not be obligated to deliver
any shares of Common Stock during any period when ManTech determines that the
vesting or delivery of the shares would violate any federal, state or other
applicable laws.

4.    Power of Attorney

As a condition of receiving the award of Restricted Shares, Eligible Person
appoints the Corporate Secretary of ManTech as his or her attorney in fact, with
full power of substitution, and authorizes him or her to provide instructions

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

to ManTech’s registrar and transfer agent for Common Stock as ManTech may deem
necessary or proper to comply with the intent and purposes of the Term Sheet,
these Standard Terms and Conditions and the Plan, including, upon the occurrence
of a forfeiture pursuant to Section 2 above, to notify the registrar and
transfer agent of the forfeiture of such shares, together with instructions to
cancel the shares forfeited. The registrar and transfer agent shall be entitled
to rely upon any notices and instructions delivered by Eligible Person’s
attorney in fact under the terms of this Section 4.

5.    Restrictions on Resales of Shares

ManTech may impose such restrictions, conditions or limitations as it determines
appropriate as to the timing and manner of any resales by the Eligible Person or
other subsequent transfers by the Eligible Person of any shares of Common Stock
that become nonforfeitable and freely transferable as a result of the vesting of
the Restricted Shares, including without limitation (a) restrictions under an
insider trading policy, (b) restrictions designed to delay and/or coordinate the
timing and manner of sales by Eligible Person and other shareholders and
(c) restrictions as to the use of a specified brokerage firm for such resales or
other transfers.

6.    Withholding Taxes

To the extent required by applicable federal, state, local or foreign law, the
Eligible Person shall make arrangements satisfactory to ManTech for the
satisfaction of any withholding tax obligations that arise by reason of the
grant or vesting of the Restricted Shares. Eligible Person may direct ManTech to
withhold the number of whole Restricted Shares otherwise deliverable to the
Eligible Person upon grant or vesting of the award that have an aggregate fair
market value (measured as of the applicable withholding date) equal to the
amount of any federal, state, or local income taxes that Eligible Person may be
subject to in connection with the grant or vesting of such shares. ManTech will
not withhold any fractional shares and if fractional share withholding would
result, Eligible Person shall make arrangements satisfactory to ManTech for
payment of the excess withholding amount in cash. ManTech shall not be required
to issue shares or to recognize the grant or vesting of such shares until such
obligations are satisfied.

7.    Non-Transferability of Restricted Shares

Unless otherwise provided by the Committee, the Eligible Person may not, prior
to the vesting of such shares, assign or transfer the Restricted Shares to
anyone other than by will or the laws of descent and distribution. ManTech may
cancel the Eligible Person’s award of Restricted Shares if the Eligible Person
attempts to assign or transfer it in a manner inconsistent with this Section 7.

8.    The Plan and Other Agreements

In addition to these Standard Terms and Conditions, the Eligible Person shall be
subject to the terms of the Plan, which are incorporated into these Standard
Terms and Conditions by this reference. Certain capitalized terms not otherwise
defined herein are defined in the Plan. The Term Sheet, these Standard Terms and
Conditions and the Plan constitute the entire understanding between the Eligible
Person and ManTech regarding the Restricted Shares. Any prior agreements,
commitments or negotiations concerning the Restricted Shares are superseded.

9.    Shareholder Rights; Dividends; No Right to Continued Service

Subject to the provisions of the Term Sheet, these Standard Terms and Conditions
and the Plan, Eligible Person shall have all of the rights of a holder of Common
Stock with respect to all of the Restricted Shares awarded to him or her, from
and after the Grant Date until the shares either vest or are forfeited,
including the right to vote such shares and to receive dividends or other
distributions paid thereon. Any cash dividends or other similar distributions
paid with respect to the Restricted Shares shall withheld and accumulated
without interest in an unfunded bookkeeping account for the Eligible Person,
which account shall be subject to the same restrictions to which the underlying
Restricted Shares are subject, and which shall be distributable in cash upon and
to the extent of the lapsing or removal of such restrictions, or forfeitable (as
the case may be) to ManTech upon and to the extent the underlying Restricted
Shares are forfeited. Nothing in the Plan, in the Term Sheet, these Standard
Terms and Conditions or any other instrument executed pursuant to the Plan shall
confer upon the Eligible Person any right to continue in ManTech’s employ or
service service or limit

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

in any way ManTech’s right to termination the Eligible Person’s employment at
any time for any reason.

11. General
In the event that any provision of these Standard Terms and Conditions is

limited to determining whether the Committee’s decision was arbitrary or
capricious. This lawsuit shall be the sole and exclusive review permitted of the
