                           SECOND AMENDED AND RESTATED
                           SECURITY AGREEMENT - PLEDGE
                    (AS THE SAME MAY BE AMENDED, MODIFIED OR
                SUPPLEMENTED FROM TIME TO TIME, THIS "AGREEMENT")

         Administaff, Inc., a Delaware corporation, whose address is 19001
Crescent Springs Drive, Kingwood, Montgomery County, Texas 77339 (herein
referred to as "Secured Party"); and Jerald L. Broussard and wife, Mary
Catherine Broussard, whose address is 707 Masters Way, Kingwood, Harris County,
Texas 77339 (herein referred to collectively as "Debtors"), agree as follows:

Section I. Creation of Security Interest.

         The Debtors hereby jointly and severally grant a security interest in,
and pledge to, Secured Party the "Collateral" (hereinafter defined) to secure
the performance and payment by Debtors of any and all indebtedness and
obligations now or hereafter owing by Debtors or either of them to Secured
Party, including, without limitation, pursuant to or under (i) that certain
Second Amended and Restated Promissory Note executed to be effective as of
September 4, 1995 in the original principal amount of $141,360.00 executed by
Debtors payable to the order of Secured Party (the "Promissory Note"); (ii) this
Agreement; and (iii) any and all "Other Documents" (hereinafter defined).

         The indebtedness and obligations of Debtors (or either of them) to
Secured Party secured by this Agreement are referred to herein as the "secured
indebtedness" or the "indebtedness secured hereby." The secured indebtedness
includes, without limitation, any and all attorney's fees now or hereafter owing
by Debtors to Secured Party.

Section II. Collateral.

         2.1 The collateral pledged by the Debtors to Secured Party pursuant to
the foregoing Section I hereof consists of (i) those shares of the common stock
issued by Secured Party described in Exhibit "A" attached hereto, (ii) those
other shares of the common stock issued by Secured Party and delivered by
Debtors or either of them unto Secured Party or its custody as contemplated by
Section 2.3 hereinbelow, and (iii) any and all shares and other rights received
by the Debtors or either of them from the issuer thereof in replacement,
substitution, or redemption of such shares described in the immediately
foregoing clauses (i) and (ii) or as a result of any share split or reverse
share split, together with any and all proceeds thereof, as the term "proceeds"
is defined by Article 9 of the Texas Business and Commerce Code (herein
collectively referred to as the "Collateral").

         2.2 Each of the Debtors shall deliver all certificates or other
instruments representing the Collateral to Secured Party, together with
appropriate instruments of transfer executed in blank, to be held by Secured
Party during the period that such items constitute Collateral under this
Agreement.



                                  Page 1 of 13

         2.3 Each of the Debtors hereby agrees with Secured Party that the
"Value" (hereinafter defined) of the Collateral shall at all times during the
term hereof be equal to at least 125% (the "Required Percentage") of the
indebtedness secured hereby from time to time, including both principal and
accrued, unpaid interest thereon, and all other costs, expenses and other
amounts owing under or pursuant to the Promissory Note, this Agreement and any
and all of the Other Documents (the product of the Required Percentage times the
indebtedness secured hereby from time to time, shall be referred to in this
Section 2.3 as the "Required Collateral Value"). Accordingly, the Debtors and
the Secured Party hereby agree as follows:

             (a) if at any time during the term hereof, the Value of the
         Collateral is less than the Required Collateral Value, each of the
         Debtors hereby jointly and severally agrees and obligates itself to
         deliver unto Secured Party or its custody such additional share
         certificates (the "Additional Shares") evidencing that number of shares
         of the common stock issued by Secured Party and owned by such Debtor as
         are sufficient so that, as of the applicable date of determination, the
         Value of the total number of shares held by Secured Party as Collateral
         hereunder shall be at least equal to the Required Collateral Value as
         determined as of such date.

             (b) if at any time during the term hereof, the Value of the
         Collateral is greater than the Required Collateral Value for a period
         of 89 consecutive days after the date of any such determination, then
         upon 30 days prior written request of the Debtors, the Secured Party
         agrees to release from the security interest of this Agreement a
         portion of the Shares (the "Excess Shares") so that the Value of the
         Collateral is equal to the Required Collateral Value as of the day that
         the Excess Shares are released; it being expressly agreed that, in the
         event the share certificates then held by Secured Party, either
         individually or in combination with other such share certificates, do
         not represent exactly the number of Excess Shares to be released,
         Secured Party shall have the right to, and is hereby directed and
         authorized by Debtors to, deliver such share certificates to the
         transfer agent of the issuer of the share certificates so that the
         issuer may issue two new certificates in exchange therefor, one
         representing the Excess Shares being released (which shall be delivered
         to the Debtors pursuant hereto) and one representing the remainder of
         the Shares of such share certificates to be continued to be held by
         Secured Party as Collateral hereunder.

         Each time that Additional Shares are delivered unto Secured Party or
         Secured Party releases any Excess Shares from the security hereof, the
         parties hereto agree to amend Exhibit "A" attached hereto accordingly.

             (c) For purposes of this Section 2.3, the Value of the Collateral
         on each day of determination shall be equal to the product of (i) the
         number of shares of common stock issued by Secured Party and which, on
         the relevant date of determination constitute Collateral hereunder
         times (ii) the closing price for such shares (on an individual basis)
         as quoted by the New York Stock Exchange (or successor thereto) at the
         close of business on 



                                  Page 2 of 13
   3

         the last trading day immediately preceding the relevant date of
         determination, as reported in the Wall Street Journal.

Section III. Payment Obligations of Debtors.

         Debtors hereby jointly and severally obligate themselves to pay to
Secured Party on written demand delivered by Secured Party to Debtors all
reasonable costs and expenses, including attorney's fees and other legal
expenses incurred or paid by Secured Party in exercising or protecting its
interests, rights and remedies under this Agreement, plus interest thereon from
date of demand until paid at the rate of ten percent (10%) per annum.

Section IV. Representations and Warranties.

         Debtors represent and warrant that:

         4.1 The Collateral is free from all liens, claims, demands, equities or
other security interests created or suffered by Debtors other than the interest
created by this Agreement.

         4.2 Debtors own the Collateral and have the right to pledge the same
and to transfer any interest therein; all consents required for the pledge of
the Collateral have been obtained; and Debtors warrant and will forever defend
their title to the Collateral against the claims and demands of all persons
whomsoever claiming or to claim the same or any part thereof.

         4.3 The execution, delivery and performance by Debtors of this
Agreement does not and will not contravene or violate any provision of any law,
rule, regulation, order, writ, judgment, injunction, decree, determination or
award presently in effect and applicable to Debtors or result in a breach of or
constitute a default (with or without the giving of notice or the lapse of time
or both) under any indenture or loan, credit or other agreement to which Debtors
or either of them are or is a party or by which Debtors or any of Debtors'
property may be bound or affected.

         4.4 This Agreement constitutes the legal, valid and binding obligation
of Debtors, enforceable against Debtors in accordance with its terms.

         4.5 No authorization, consent, approval, license, order or exemption
of, or filing or registration with, any court or governmental department,
commission, board, bureau, agency or instrumentality, domestic or foreign, is or
will be necessary to the valid execution, delivery or performance by Debtors of
this Agreement or to the enforcement hereof by Secured Party.

Section V. Covenants.

         5.1 Debtors covenant and agree with Secured Party as follows:



                                  Page 3 of 13
   4

             (a) Debtors will furnish to Secured Party such stock powers and
other instruments as may reasonably be required by Secured Party to facilitate
the transfer of the Collateral.

             (b) Debtors will cause to be paid prior to delinquency all taxes
and assessments hereafter levied or assessed against the Collateral, or any part
thereof, or against the Secured Party for or on account of the interest created
by this Agreement.

             (c) If the validity of this Agreement, any provision hereof, or the
priority of the security interest granted by this Agreement is challenged or
questioned, or if any legal proceedings are instituted with respect thereto,
Debtors will give prompt written notice thereof to Secured Party and, at
Debtors' own cost and expense, will take all necessary and proper steps for the
defense of such legal proceedings.

             (d) Debtors will on request of Secured Party (i) promptly correct
any defect or error which may be discovered in any instrument or document
executed by Debtors for the purpose of giving effect to this Agreement or of
fulfilling the obligations of Debtors under this Agreement; (ii) execute,
acknowledge, deliver and record or file such further instruments and documents
(including financing statements and continuation statements) and do such further
acts as may reasonably be necessary, desirable or proper to carry out more
effectively the purposes of this Agreement; and (iii) Debtors will pay all
reasonable costs connected with any of the foregoing.

             (e) Debtors will not sell, exchange, lend, assign, transfer or
otherwise dispose of all or any part of the Collateral or any interest therein,
or permit any of the foregoing, without the prior written consent of Secured
Party.

             (f) Debtors hereby obligate themselves, jointly and severally, to
pay (or reimburse Secured Party) for all reasonable filing fees, taxes,
brokerage fees and commissions, Uniform Commercial Code search fees, escrow
fees, attorney's fees, and all other costs and expense of every character
incurred by Secured Party in connection with this Agreement or the Collateral
and will reimburse Secured Party for all such expenses incurred by it. Debtors
hereby obligate themselves, jointly and severally, to pay (or reimburse Secured
Party) for its reasonable expenses and expenditures, including reasonable
attorney's fees and legal expenses, incurred or expended in connection with
Secured Party's rightful exercise of its rights and remedies hereunder and/or
Secured Party's protection of the Collateral and its security interest therein.
Amounts to be paid hereunder by Debtors to Secured Party will be payable upon
written demand from Secured Party delivered to Debtors and will bear interest
from date of demand until paid at the rate of ten percent (10%) per annum.

             (g) Debtors will furnish to Secured Party such information as
Secured Party may reasonably request with respect to the Collateral.

         5.2 If Debtors fail to perform any act (including the payment of money)
which this Agreement requires of Debtors, Secured Party, in Debtors' names or in
its own name, may, but is 



                                  Page 4 of 13
   5

not obligated to, perform or cause to be performed such act, and any expenses so
incurred by Secured Party will be payable by Debtors upon written demand from
Secured Party delivered to Debtors and will bear interest from date of demand
until paid at the rate of ten percent (10%) per annum.

Section VI. Voting Rights.

         Unless and until an "Event of Default" (hereinafter defined) occurs,
Debtors are entitled to exercise all voting and consensual powers and rights
relating to the Collateral or any part thereof for all purposes not inconsistent
with the terms of this Agreement.

Section VII. Event of Default.

         It will be an Event of Default under this Agreement if there occurs any
default in Debtors' performance of their obligations under this Agreement or in
the payment of any of the secured indebtedness when due or declared due which
default is not cured within fifteen (15) days following Debtors' receipt of
notice from Secured Party of such default (herein referred to as an "Event of
Default").

Section VIII. Remedies in Event of Default.

         8.1 Upon the occurrence of any Event of Default, and at any time
thereafter if such Event of Default has not been cured, Secured Party may, after
giving all notices required by law or this Agreement, sell the Collateral or any
part thereof in accordance with all applicable laws and regulations at public or
private sale or by sale at a broker's board or on a securities exchange. If (i)
the Collateral is sold at public sale or (ii) the Collateral is sold at a
private sale and is of a type customarily sold in a recognized market or is of a
type which is the subject of widely distributed standard price quotations,
Secured Party may be the purchaser of the Collateral and may apply the purchase
price therefor against the indebtedness secured hereby. Ten (10) days prior to
any public sale of the Collateral or ten (10) days prior to the date after which
the Collateral may be sold at private sale, Secured Party shall give to Debtors
at the address set forth herein notice of Secured Party's intention to make such
public or private sale. Such notice, in case of public sale, must state the time
and place fixed for the sale, and in case of sale at a broker's board or on a
securities exchange, must state the board or exchange at which such sale is to
be made and the day on which the Collateral or that portion thereof so being
sold will first be offered for sale at such board or exchange. Any such public
sale will be held at such time or times, during ordinary business hours and at
such place or places, as Secured Party may fix in the notice of such sale. At
any sale the Collateral may be sold in one lot as an entirety or in separate
parcels as Secured Party may determine. Secured Party will not be obligated to
make any sale pursuant to any such notice. If any part of the Collateral is sold
on credit or for future delivery, Secured Party will retain the Collateral so
sold until the full purchase price is paid by the purchaser thereof. If such
purchaser fails to pay for Collateral so sold, Secured Party may again act to
sell the Collateral in compliance with this Agreement and applicable law. Each
of the methods of disposition described in this Section are deemed to constitute
disposition in a commercially reasonable manner. Notwithstanding anything 



                                  Page 5 of 13
   6

to the contrary contained herein, the Federal Securities Act of 1933, as
amended, other applicable federal and state laws and regulations, and conditions
or limitations stated on the face or back of the certificates representing the
Collateral may impose restrictions or limitations on Secured Party's ability to
dispose of all or part of the Collateral in the enforcement of its rights and
remedies hereunder. Therefore, upon the occurrence of an Event of Default,
Secured Party is authorized to sell the Collateral or any part thereof at one or
more private sales at which the prospective bidders and purchasers are
restricted to persons who represent and warrant that they will purchase the
Collateral or a portion thereof for investment for their own accounts and not
with a view to distributing or reselling same, in a manner which will not
require that the Collateral, or any part thereof, be registered in accordance
with the Securities Act of 1933, as amended, or the rules and regulations
promulgated thereunder, or any other law of regulations, at the best price
reasonably obtainable by Secured Party at any such private sale or other
disposition in the manner mentioned above. Debtors agree (i) that if the Secured
Party sells the Collateral, or any portion thereof, at a private sale or sales
under this Section, Secured Party will have the right to rely upon the advice
and opinion of any member firm of a national securities exchange as to the best
price reasonably obtainable therefor upon such a private sale, and (ii) that in
the absence of fraud, sale of the Collateral or portion thereof at such price
will be conclusive evidence that Secured Party obtained the reasonable fair
market value.

         8.2 Upon the occurrence of any Event of Default, and at any time
thereafter, Secured Party shall have the rights of a secured party after default
under the Texas Business and Commerce Code, as modified by this Agreement. In
connection with the exercise of those rights or of any other rights of Secured
Party granted by this Agreement:

             (a) written notice given to Debtors as provided herein ten (10)
days prior to the date of public sale of the Collateral or prior to the date
after which private sale of the Collateral will be made constitutes reasonable
notice;

             (b) so long as any portion of the secured indebtedness remains
outstanding, sale by Secured Party of less than the whole of the Collateral will
not exhaust the rights of Secured Party hereunder, and Secured Party may make
successive sales hereunder until the whole of the Collateral shall be sold; and

             (c) Secured Party may appoint or delegate any one or more persons
as its agent to perform any act or acts necessary or incident to any sale held
by Secured Party, including the sending of notices and the conduct of sale, but
in the name and on behalf of Secured Party.

         8.3 The remedies provided for in this Agreement are cumulative of all
remedies provided for in any other agreement securing payment of the secured
indebtedness and all other applicable remedies existing at law or in equity, and
resort to any remedy provided for in this Agreement or under any other agreement
or by law will not prevent the concurrent or subsequent employment of any other
appropriate remedy or remedies.



                                  Page 6 of 13
   7

         8.4 Secured Party may resort to any security given by this Agreement or
to any other security now existing or hereafter given to secure the payment of
the secured indebtedness, in whole or in part, and in such portions and in such
order as may seem best to Secured Party, and no such action will in any manner
be considered as a waiver of any of the rights, benefits or security interest
evidenced by this Agreement.

Section IX. Additional Agreements.

         9.1 Upon the payment and performance in full of the secured
indebtedness, all of Secured Party's rights under this Agreement will terminate,
the Collateral will automatically be released from the security interest
evidenced hereby, and all documents and instruments filed in any public office
for the perfection of such security interest will be released, canceled and
terminated by Secured Party in due form at Debtors' cost.

         9.2 Secured Party may waive any default without waiving any other prior
or subsequent default. Secured Party may remedy any default without waiving the
default remedied. Failure alone by Secured Party to exercise any right, power or
remedy upon any default may not be construed as a waiver of such default or as a
waiver of the right to exercise any such right, power or remedy at a later date.
No single or partial exercise by Secured Party of any right, power or remedy
hereunder will, without more, exhaust the same or will preclude any other or
further exercise thereof. No modification or waiver of any provision hereof nor
consent to any departure by Debtors therefrom will be effective unless the same
is in writing and signed by Secured Party, and thensuch waiver or consent will
be effective only in the specific instances, for the purpose for which given and
to the extent therein specified. Acceptance by Secured Party of any payment in
an amount less than the amount then due on any secured indebtedness will be
deemed an acceptance on account only and will not in any way affect the
existence of a default hereunder.

         9.3 Secured Party may at any time and from time to time in writing (i)
waive compliance by Debtors with any covenant herein made by Debtors to the
extent and in the manner specified in such writing; (ii) release any part of the
Collateral, or any interest therein, from the security interest of this
Agreement; or (iii) release any party liable, either directly or indirectly, for
the secured indebtedness or for any covenant herein or in any other instrument
now or hereafter securing the payment of the secured indebtedness without
impairing or releasing the liability of any other party. No such act will in any
way impair the rights of Secured Party hereunder or impair or release the
liability of any party except to the extent specifically agreed by Secured Party
in such writing.

         9.4 The security interest and other rights of Secured Party hereunder
will not be impaired by any indulgence, moratorium or release granted by Secured
Party, including, but not limited to, (i) any renewal, extension or modification
which Secured Party may grant with respect to any secured indebtedness; (ii) any
surrender, compromise, release, renewal, extension, exchange or substitution
which Secured Party may grant in respect of any item of the Collateral, or any
part thereof or any interest therein, or (iii) any release or indulgence granted
to any endorser, guarantor or surety of any secured indebtedness.



                                  Page 7 of 13

         9.5 A carbon, photographic or other reproduction of this Agreement or
of any financing statement relating to this Agreement will be sufficient as a
financing statement.

         9.6 If ownership of the Collateral or any part thereof becomes vested
in a person other than Debtors, Secured Party may, without notice to Debtors,
deal with such successor or successors in interest with reference to this
Agreement and to the indebtedness secured hereby in the same manner as with
Debtors; provided, however, that the foregoing shall not limit, diminish, alter
or otherwise affect Debtors' covenants set forth in Section 5.1(e) hereinabove.
No sale of the Collateral, no forbearance on the part of Secured Party and no
extension of the time for the payment of the indebtedness secured hereby given
by Secured Party will operate to release, discharge, modify, change or affect,
in whole or in part, the liability of Debtors or any other person for the
payment of the indebtedness secured hereby, except as set forth in Section X
hereinbelow.

         9.7 Any notices, offers, approvals and other communications hereunder
must be in writing and, except when receipt is required to start the running of
a period of time, will be deemed given the second day after its mailing by one
party by certified or registered United States mail, postage prepaid and return
receipt requested, to the other party addressed as set forth in the first
paragraph of this Agreement. Any writing which may be mailed pursuant to the
foregoing may also be delivered by hand or transmitted by telegraph, telex or
telecopier and will be effective when received by the addressee. Either party
may, from time to time, specify as its address for purposes of this Agreement
any other address by giving ten (10) days' prior written notice thereof to the
other party.

         9.8 This Agreement is binding upon, and inures to the benefit of,
Secured Party, Debtors, and their respective heirs and assigns.

         9.9 If any term or provision of this Agreement or the application
hereof to any person or circumstance is invalid or unenforceable to any extent,
the remainder of this Agreement will not be affected thereby, and each term and
provision of this Agreement will be valid and in force to the fullest extent
permitted by law.

         9.10 Secured Party may, at any time after the occurrence of an Event of
Default, personally or by an agent designated by it, execute, sign, endorse,
transfer or deliver in the name of Debtors, notes, checks, drafts or other
instruments for the payment of money and receipts or any other documents
necessary to evidence, perfect and realize upon the security interests and
obligations of this Agreement. Any third party acting in good faith may rely on
the affidavit of Secured Party that an Event of Default has occurred for all
purposes under this Agreement and is released by Debtors from and against any
claim by Debtors for any action undertaken in such reliance.

         9.11 Secured Party's duty with respect to the care and custody of the
Collateral is solely to use reasonable care in the custody and preservation of
the Collateral in Secured Party's possession. Secured Party will not be
responsible in any way for any depreciation in the value of the Collateral, nor
does any duty or responsibility whatsoever rest upon Secured Party to act to
preserve 



                                  Page 8 of 13
   9

rights against prior parties or to enforce collection of the Collateral by legal
proceedings or otherwise, the duty of the Secured Party being solely to receive
collections, remittances and payments on such Collateral as and when made to
Secured Party. If Debtors instruct Secured Party, in writing or orally, to
deliver any or all of the Collateral to a broker or other third person, and
Secured Party agrees to do so, the following conditions are deemed conclusively
to be a part of Secured Party's agreement, whether or not they are specifically
mentioned to Debtors at the time of such agreement: (i) Secured Party assumes no
responsibility for verifying the genuineness or authenticity of the authority of
any person purporting to be a messenger, employee or representative of the
broker or other third person to whom Debtors have directed Secured Party to
deliver the Collateral, or the genuineness or authenticity of any document of
instructions delivered by any such person; (ii) by requesting any such delivery,
Debtors will be considered to have assumed all risk of loss as to the
Collateral; (iii) Secured Party's sole responsibility will be to deliver the
Collateral to the person purporting to be the broker or other third person
described by Debtors, or a messenger, employee or representative thereof, and
(iv) Secured Party and Debtors expressly agree that compliance by Secured Party
with the immediately foregoing clause (iii) constitutes reasonable care.

         9.12 The headings of the various subdivisions of this Agreement are for
convenience of reference only and do not define or limit any of the terms or
provisions hereof. All pronouns are deemed to refer to the masculine, feminine,
neuter, singular or plural as the identity of the person or persons referred to
may require. Terms used in this Agreement which are defined in the Texas
Business and Commerce Code are used with the meanings as therein defined.

         9.13 All obligations of Debtors hereunder shall be joint and several.

         9.14 This Agreement is governed by and will be construed in accordance
with the laws of the State of Texas and when and where applicable, the laws of
the United States of America.

         9.15 It is the intention of Debtors and Secured Party to comply
strictly with all applicable usury laws. Interest on the indebtedness secured
hereby, however denominated, shall not exceed the maximum amount of nonusurious
interest that may be contracted for, taken, reserved, charged, collected, or
received under applicable law; any interest collected or received in excess of
such maximum nonusurious amount shall be deemed a mistake and credited against
the unpaid principal balance then outstanding of the indebtedness secured hereby
or, if such indebtedness has been repaid in full, refunded to Debtors, and the
effective interest rate shall automatically be reduced to the maximum
nonusurious contract rate and amount allowed for such indebtedness under
applicable law. This provision shall override all demands and charges, the
effect of all prepayments, and all contrary provisions in this Agreement, the
instruments which evidence the indebtedness secured hereby, and any and all
other instruments, documents, or other agreements executed as security for such
indebtedness or otherwise in connection therewith, whether now existing or
hereafter executed.

Section X. Recourse Obligation.

         It is the express understanding of the Debtors and Secured Party that
any judgment for the repayment of the indebtedness secured hereby or interest
thereon will be enforced first against the Collateral and, second, only to the
extent that the indebtedness evidenced by the Promissory Note or interest
thereon is not satisfied by the Collateral, against the Debtors or either of
them personally or any property of the Debtors or either of them to the full
extent of such deficiency; in any action to collect any amount payable hereunder
or to enforce performance of any of the other provisions of this Agreement;
provided, however:

             (a) Nothing herein contained shall be construed as limiting or
         impairing the enforcement against the Collateral or otherwise
         prohibiting Secured Party from exercising any and all remedies which
         this Agreement, the Promissory Note, or any other document, instrument
         or other agreement executed as security for or otherwise in connection
         with the indebtedness secured hereby (herein referred to collectively
         as the "Other Documents") permit, so long as the exercise of any remedy
         shall only extend to execution against or recovery out of any property
         of Debtors or either of them in addition to the Collateral in any
         action to foreclose the security interest and pledge hereof or to
         collect any indebtedness secured hereby at such time as the Collateral
         is fully exhausted and then only to the extent any deficiency was not
