                                            of Common Stock

                       WARRANT TO PURCHASE COMMON STOCK
                                      of
                         COMMAND SECURITY CORPORATION
                         Void after January 31, 2011
                           Issued February 1, 2001
                            Amended June 28, 2001

         This certifies that, for value received, Martin C. Blake, Jr. (the
"Holder"), is entitled, subject to the terms set forth below, at any time
before January 31, 2011 to purchase from Command Security Corporation, a New
York corporation (the "Company"), with its principal office at Route 55,
Lexington Park, Lagrangeville, NY 12540, Fifty Thousand (50,000) shares (the
"Shares") of common stock, $.0001 par value of the Company, upon surrender
hereof, at the principal office of the Company, with the Election to Purchase
form attached hereto duly executed, and simultaneous payment therefor in
lawful money of the United States, or otherwise as hereinafter provided, at a
price equal to $.75 per full Share. (Such price hereinafter referred to as
the "Purchase Price"). The Purchase Price, number and character of such
Shares are subject to adjustment as provided below, and the term "Shares"
shall mean, unless the context otherwise requires, the stock and other
securities and property at the time receivable upon the exercise of this
Warrant. The term "Warrant" as used herein shall include this Warrant and any
warrants delivered or deliverable in substitution or exchange thereof as
provided herein. This Warrant is an incentive stock option pursuant to the
Company's 2000 Stock Option Plan.

                                      1

<PAGE>

         1. (a) Exercise. This Warrant may be exercised at any time after May
1, 2004 or from time to time thereafter, on any business day for up to the
number of Shares called for hereby. This Warrant shall be exercised by
surrendering it at the principal office of the Company, with the Election to
Purchase form duly executed, together with payment in cash or by certified or
official bank check, payable to the order of the Company, of the sum obtained
by multiplying (i) the number of Shares indicated on the Election to Purchase
form by (ii) the appropriate Purchase Price. Subject to the prior written
consent of the Stock Option Committee (the "Committee"), which consent may be
withheld in the sole discretion of the Committee, the purchase price may be
paid in whole or in part through the surrender of previously acquired Shares
at their fair market value on the exercise date. In the event the Holder
ceases for any reason to be employed by the Company, this Warrant, to the
extent not previously exercised, shall terminate and become null and void
immediately upon such termination. This Warrant may be exercised for less
than the full number of Shares at the time called for hereby, but not for
less than 1,000 Shares unless the number of Shares called for on the face
thereof is less than 1,000 in which event the minimum number will be the
number of Shares called for on the face. Upon a partial exercise this Warrant
shall be surrendered, and a new Warrant of the same tenor and for the
purchase of the number of such Shares not purchased upon such exercise shall
be issued by the Company to Holder. A Warrant shall be deemed to have been
exercised immediately prior to the close of business on the date of its
surrender for exercise as provided above, and the person entitled to receive
the Shares issuable upon such exercise shall be treated for all purposes as
the holder of such Shares of record as of the close of business on such date.
As soon as practicable on or after such date, the Company shall issue and
deliver to the person or persons entitled to receive the same a certificate
or certificates for the number of full Shares issuable upon such exercise,
together with cash, in lieu of any fraction of a Share, equal to such
fraction of the current market value of one full Share. If surrendered by
mail, the date of surrender shall be the date the Warrant is mailed
consistent with the requirements for notice as described in Section 7.

         (b) Termination. This Warrant is subject to termination if
the Holder ceases to be an employee of the Company as provided under the
Company's 2000 Stock Option Plan.

         (c) Vesting. The Holder of this Warrant is further restricted in that
the Warrant may not be exercised unless and until the Company's Board of
Directors determines that the confidential targets for the Aviation Services
Division of the Company as stated in the Company's Business Plan dated March
13, 2000 and approved by the Board in November of 2000 shall have been
satisfied or waived by the Company's Board of Directors in its sole
discretion. This Board determination will be made by a vote within 30 days
after April 30, 2004. The Company's confidential targets have been made
accessible to the Holder on a confidential basis and the Holder has
acknowledged such on the receipt annexed hereto.

                                      2

<PAGE>

         2. Payment of Taxes. All Shares issued upon the exercise of this
Warrant shall be validly issued, fully paid and nonassessable, and the
Company shall pay any transfer taxes (excluding income tax, capital gains
tax, etc.) and other governmental charges that may be imposed in respect of
the issue or delivery thereof. The Company shall not be required, however, to
pay any tax or other charge imposed in connection with any transfer involved
in the issue of any certificate for Shares in any name other than that of the
registered Holder of the Warrant surrendered in connection with the purchase
of such Shares, and in such case the Company shall not be required to issue
or deliver any stock certificate until such tax or other charge has been paid
or it has been established to the Company's satisfaction that no tax or other
charge is due.

         3. Protection Against Dilution. The Shares covered by this Warrant
and the Purchase Price payable therefor shall be subject to appropriate
adjustment as follows:

         (a) If a Share dividend is declared on the Shares, or if an increase
or decrease has been effected in the number of outstanding Shares by reason
of subdivision of such Shares or combination of such Shares into a lesser
number, the number of Shares which may thereafter be purchased under this
Warrant shall be the number of Shares which would have been received by the
Holder on such dividend, subdivision or combination had the Holder been the
Holder of record of the number of Shares then under this Warrant but not
theretofore purchased and issued.

         (b) If there is any other capital reorganization or reclassification
of the stated capital of the Company, or any consolidation or merger of the
Company with any other corporation or corporations, or the sale or
distribution of all or substantially all of the Company's property and
assets, adequate provision shall be made by the Company so that there shall
remain and be substituted under this Warrant the Shares, securities, or
assets which would have been issuable or payable in respect of or in exchange
for the Shares then remaining under this Warrant and not theretofore
purchased and issued hereunder, as if the Holder of this Warrant had been the
owner of such Shares on the applicable record date.

         (c) If any of the events described in Sections 3(a) or (b) occur,
the Purchase Price shall be adjusted to that price determined by multiplying
the then current Purchase Price by a fraction (x) the numerator of which
shall be the total number of outstanding Shares immediately prior to such
event and (y) the denominator of which shall be the total number of
outstanding Shares immediately after such event.

         4. Loss or Mutilation. Upon receipt by the Company of evidence
satisfactory to it (in the exercise of reasonable discretion) of the
ownership of and the loss, theft, destruction or mutilation of any Warrant
and (in the case of mutilation) upon surrender and cancellation thereof, the
Company will execute and deliver in lieu thereof a new Warrant of like tenor.

                                      3

<PAGE>

         5. Reservation of Stock. The Company shall at all times reserve and
keep available for issue upon the exercise of Warrants such number of its
authorized but unissued Shares as will be sufficient to permit the exercise
in full of all outstanding Warrants.

         6. Restrictions on Transfer. In accordance with the Company's 2000
Stock Option Plan, this Warrant and all rights hereunder shall be
nontransferable and nonassignable by the Holder accept to the extent that the
representatives of the estate or the heirs of the deceased option Holder may
be permitted to exercise them, and during the Holder's lifetime shall be
exercisable only by the Holder.

         7. Notices. All notices and other communications from the Company to
the Holder of this Warrant shall be mailed by first-class registered or
certified mail, postage-prepaid, to the last address furnished to the Company
in writing by the Holder.

         8. No Rights as Shareholder; Limitation of Liability. This Warrant
shall not entitle any Holder hereof to any of the rights of a shareholder of
the Company. No provision hereof, in the absence of affirmative action by the
Holder hereof to purchase Shares, and no mere enumeration herein of the
rights or privileges of the Holder hereof, shall give rise to any liability
of such Holder for the purchase price of the Shares issuable on exercise of
this Warrant or as a shareholder of the Company, whether such liability is
asserted by the Company or by creditors of the Company. No provision of this
Warrant and no right or option granted or conferred hereunder shall in any
way limit, affect, or abridge the exercise by the Company of any of its
corporate rights or powers to revise its corporate targets, financial or
otherwise, to recapitalize, amend its certificate of incorporation,
reorganize, consolidate or merge with or into another corporation, to
transfer all or any part of its property or assets, or to exercise any other
of its corporate rights and powers.

         9. Change; Waiver. Neither this Warrant nor any term hereof may be
changed, waived, discharged or terminated orally but only by an instrument in
writing signed by the party against which enforcement of the change, waiver,
discharge or termination is sought.

         10. Headings. The headings in this Warrant are for purposes of
convenience in reference only, and shall not be deemed to constitute a part
thereof.

         11. Stock Option Plan. This Warrant is granted pursuant to the terms
of the Company's 2000 Stock Option Plan, the terms of which are incorporated
herein by reference, and the Warrant shall in all respects be interpreted in
accordance with the said Plan. The Committee shall construe and interpret the
Plan and this instrument, and its interpretations of determinations shall be
conclusive and binding on the parties hereto and any other person claiming an
interest hereunder, with respect to any issue arising hereunder or
thereunder.

                                      4

<PAGE>

         12. Employment. Neither the granting of this Warrant nor its
exercise shall be construed as the granting to the Holder of any right with
respect to continuance of employment. Except as may otherwise be limited by a
written agreement between the Company and the Holder, the right of the
Company to terminate at will the Holder's employment with it at any time
(whether by dismissal, discharge, retirement or otherwise) is specifically
reserved by the Company, as the employer and acknowledged by the Holder.

         13. Amendment. This Warrant may be amended by the Board or the
Committee at any time (i) if the Board of Directors or Committee determine in
their sole discretion that amendment is necessary or advisable in the light
of any addition to or change in the Internal Revenue Code or in the
regulations issued thereunder, or any federal or state securities law or
other law or regulation, which change occurs after the date hereof and by its
terms applies to the Warrant; or (ii) other than in the circumstances
described in clause (i), with the consent of the Holder.

         14. Law Governing. This Warrant is delivered in New York and shall
be construed and enforced in accordance with and governed by the laws of such
State.
