                                VALIDITY GUARANTY

                         Dated as of December ___, 2002

GREENFIELD COMMERCIAL CREDIT, L.L.C. ("Greenfield")

     THIS VALIDITY GUARANTY ("Guaranty"), effective as of the above date, sets
forth the terms and conditions upon which the undersigned (whether one or more
in number, referred to herein as "we," "us" or "our" and whom, if two or more in
number, shall be jointly and severally bound) agrees to guaranty certain
agreements entered into by you:

     1. Underlying Facts.

        (a) You have agreed to enter into a certain Loan and Security Agreement
of even date herewith (the "Agreement") with DIVERSIFIED CORPORATE RESOURCES,

loans against and be granted a security interest in various accounts receivable
of the Credit Parties ("Financed Accounts Receivable").

        (b) Borrower has executed and delivered to you the Agreement and other
documents executed in connection therewith (the "Loan Documents").

        (c) You require as a condition of entering into the Agreement that we

with the Credit Parties, we absolutely and unconditionally guarantee to you the

and obligations of any Credit Party to you which arise out of, and to the extent
of: (a) the failure of any Credit Party to remit funds it receives on any
Financed Accounts Receivable during the period of time prior to ten (10) days
from the date that you receive written notice from the Borrower that J. Michael
Moore ("Moore") is no longer an officer of the Borrower, and/or (b) any loss on
any Financed Accounts Receivable that is incurred due to the fraud or
misrepresentation of any Credit Party or any officers, directors, agents,
employees or representatives of any Credit Party (collectively, the
"Obligations"). In addition, we shall pay you all costs incurred, including
reasonable attorneys' fees, in enforcing payment and performance of this
Guaranty.

obligation is held by you as collateral security for the Obligations;

        (i) release or substitute collateral, guaranties or guarantors; and/or

        (j) amend the Agreement whether or not such amendment increases the
likelihood of our liability under this Guaranty.

     4. Our Waivers. We unconditionally and absolutely waive:

        (a) any obligation you may have to protect, secure or insure any of the
collateral given to secure the payment of the Obligations or to ensure any
Credit Party's compliance with any such obligation imposed on any Credit Party
under the Loan Documents;

        (b) any right to participate in any of the collateral given as security
for the payment under the terms of the Agreement;

as security for the Obligations;

        (j) any failure, neglect or omission on your part to realize upon or
protect the Obligations or any collateral given as security therefor;

        (k) any right to insist that you prosecute collection of the Obligations
or resort to any collateral given as security for the Obligations or to proceed
against any Credit Party or against any other guarantor or surety prior to
enforcing this Guaranty; provided, however, in your sole discretion you may,

                                       2

<PAGE>

either in a separate action or in an action pursuant to this Guaranty, pursue
your remedies against any Credit Party or any other guarantor or surety, without
affecting your rights under this Guaranty;

        (l) any right to participate in or direct such action or proceeding in
(k) above;

        (m) any right to notice of advances made to any Credit Party under the
Loan Documents;

        (n) any right relating to notice or any order, method or manner of

        (o) any right to insist that you disburse the full principal amount due
under the Loan Documents to any Credit Party or the order, method, manner or
amounts disbursed pursuant to the Loan Documents.

     5. Our Revocation. This Guaranty shall remain in full force and effect and
be binding upon us and shall inure to your benefit until thirty (30) days after
the date this Guaranty is expressly terminated by notice in writing delivered
personally to or received by registered mail by you at 1301 W. Long Lake, Suite
190, Troy, Michigan 48098, or such other address you specify in writing to us;
provided, however, that this Guaranty shall remain in full force and effect
regardless of such termination with respect to all Obligations in existence on
the date of such termination (including any subsequent extension, renewal,
modification, amendment or compromise thereof and all subsequently accruing
interest and other charges thereon) until all such Obligations are fully
satisfied and paid to you. In the absence of any termination of this Guaranty in
accordance with the provisions of this Section 5, we agree that until all
Obligations and our obligations under this Guaranty are satisfied, this Guaranty
shall remain in full force and effect notwithstanding that from time to time any
Credit Party may be free from all Obligations.

     6. Additional Waivers. We will not assert against you and do hereby
unconditionally and absolutely waive all defenses of any Credit Party and any
defenses we may have against you, including, but not limited to, defenses of
waiver, release, discharge, bankruptcy, statute of limitations, res judicata,
statute of frauds, anti-deficiency statute, fraud, fraudulent conveyance,
insolvency, lack of consideration, merger of claims under this Guaranty with the
Obligations, ultra vires acts, usury, illegality or unenforceability, any
defense which, under principles of guaranty, suretyship or other applicable law,
would operate to impair or diminish our liability under this Guaranty, any
set-off available against you by any Credit Party whether or not on account of a
related transaction, and we shall be and remain liable for any deficiency
remaining after foreclosure of any mortgage or any security interest securing
the Obligations notwithstanding any provisions of law that may prevent you from
enforcing such deficiency against any Credit Party.

     7. Effect of Bankruptcy. Our liability shall not be affected nor impaired
by any voluntary or involuntary dissolution, sale or other disposition of all or
substantially all of the collateral or assets of any Credit Party, receivership,
insolvency proceeding, bankruptcy, assignment for the benefit of creditors,
reorganization proceeding, arrangement, composition or readjustment of, or other
similar event or proceeding affecting any Credit Party or any of its assets and
that upon the institution of any of the above actions, at your sole discretion
and without notice thereof or demand therefor, our obligations hereunder shall
become due and payable and enforceable against us, whether or not the
Obligations are then due and payable.

                                       3

<PAGE>

     8.  Marshalling of Assets. We waive any defense or claim relating to any
obligation you may have to marshal the collateral or other assets of any Credit
Party for our benefit, and we agree that you shall be under no duty to marshal
the assets of any Credit Party for our benefit or any third party.

     9.  Absolute and Unconditional. No act or thing, except for payment in
full, which but for this provision might or could in law or in equity act as a
release of our liabilities, shall in any way affect or impair this Guaranty.
This shall be a continuing, absolute and unconditional Guaranty, and our
liability on this Guaranty shall be immediate. To the extent of my obligation
heeunder, you may have immediate recourse against us for full and immediate
payment and performance of the Obligations, or any part thereof, at any time
after the Obligations have not been paid or performed when due (whether by
acceleration or otherwise). Subject to Section 5 hereof, this Guaranty shall
remain in full force and effect until the Obligations have been paid in full
notwithstanding any change or modification of our relationship with any Credit
Party which exists as of the date hereof.

     10. Subordination. Except as herein otherwise provided, all indebtedness
and liability now or at any time or times hereafter owing to us by any Credit
Party is hereby subordinated to the Obligations and any payment of indebtedness
or liabilities of any Credit Party to us shall be held by us in trust for you,
segregated from other funds, and shall, immediately upon our receipt, be turned
over to you in the exact form received by us (duly endorsed to you, if
required), to be applied against the Obligations, whether matured or unmatured,
in such order as you may determine. This provision shall not be applicable to
the following: salary, bonuses, other forms of compensation or expense reports
earned by me or payable to me by the Borrower for any period of time prior to
the date that Lender gives the Borrwoer written notice that the Borrower is in
default under the Agreement.

     11. Subrogation. We waive any claim or other right which we may now have or
may hereafter acquire against any Credit Party or any other person that is
primarily or contingently liable on the obligations that arise from the
existence or performance of our obligations under this Guaranty, including,
without limitation, any right of subrogation, reimbursement, exoneration,
contribution, indemnification, any right to participate in any claim or remedy
you may have against any Credit Party or any collateral security therefor, which
you now have or hereafter acquire, whether or not such claim, remedy or right
arises in equity, or under contract, statute or common law. If any amount shall
be paid to us contrary to the terms of this Section 11, such amount shall be
held by us in trust for you, segregated from our other funds, and shall,
immediately upon receipt by us, be turned over to you in the exact form received
by us (duly endorsed to you, if required), to be applied against the
Obligations, whether matured or unmatured, in such order as you may determine.

     12. Set-Off. Upon the occurrence and continuation of a Default (as defined
in the Agreement) under the Loan Documents, and to the extent of my actual
liability under the terms of this Guaranty, we hereby authorize you at any time
and from time to time to set off and apply any deposit held and any other
indebtedness at any time owing by you to us or for our account against our
Obligations and liabilities to you.

     13. Reinstatement. This Guaranty shall continue to be effective or be
reinstated, as the case may be, if at any time any payment of all or any part of
the Obligations is rescinded or must otherwise be returned by you upon the
insolvency, bankruptcy, reorganization, liquidation or dissolution of any Credit
Party or otherwise, all as if such payment had not been made. If and to the
extent we have any obligations actually payable under this Guaranty, we hereby
indemnify and hold you harmless from and against all costs and expenses you may
incur, including reasonable attorneys' fees, in connection with the defense of a
bankruptcy preference action, fraudulent conveyance action, lien avoidance
action, or other action relating to your right to retain amounts previously paid
to you in respect of the Obligations, and for all costs and expenses you may
incur relating to the Obligations or the security therefor during any

                                       4

<PAGE>

applicable redemption period following the foreclosure of any mortgage or
security interest in any collateral, including but not limited to, taxes and
insurance costs in respect of such collateral, whether or not any Credit Party
would be liable to you for such costs and expenses.

     14. Your Reliance. We acknowledge that this Guaranty is executed in order
to induce you to enter into the Agreement and disburse the amounts due under the
Loan Documents with the intent that you will rely upon it in entering into the
Agreement and disbursing such amounts with the knowledge that you would not
enter into the Agreement or disburse such amounts but for execution of this
Guaranty. Disbursement of any part of the amounts due under the Loan Documents,
without any further action or notice, shall constitute conclusive evidence of
your reliance hereon.

     15. Representations and Covenants. Each of the undersigned hereby
represents and agrees as follows:

         (a) We are fully aware of the financial condition of each Credit Party
and deliver this Guaranty based solely upon our own independent investigation
and in no part upon any representation or statement made by you with respect
thereto. We are in a position to and hereby assume full responsibility for
obtaining any additional information concerning each Credit Party's financial
condition as we may deem material to our obligations hereunder. We are not
relying upon nor expecting you to furnish us any information in your possession
concerning each Credit Party's financial condition.

         (b) Other than proceeds paid to any Credit Party pursuant to the Loan
Documents which may be used by such Credit Party to pay us salary, bonuses or
dividends, none of those amounts will be used for (i) our personal, family or
household purposes, or (ii) to purchase or otherwise obtain title to residential
property which is security for our obligations under this Guaranty.

     16. Security. The performance of our obligations under this Guaranty is
unsecured, other than for such rights of set-off which you may have by virtue of
your holding our property.

     17. Miscellaneous.

         (a) No right or remedy conferred upon or reserved to you under this
Guaranty is intended to be exclusive of any other available remedy or remedies
but each and every remedy shall be cumulative and shall be in addition to every
other remedy given under this Guaranty, or the Loan Documents, or as may now or
hereafter exist at law or in equity. No waiver, amendment, release or

                                        5

<PAGE>

modification of this Guaranty shall be established by conduct, custom or course
of dealing, but only by an instrument in writing duly executed by you.

         (b) Whenever the context requires or permits the singular shall include
the plural, the plural shall include the singular and the masculine, feminine
and neuter shall be freely interchangeable.

         (c) This Guaranty is delivered in and made in, is executed with respect
to and shall in all respects be construed pursuant to and governed by the laws
of the State of Michigan.

         (d) This Guaranty and each and every part hereof, shall be binding on
us and our heirs, administrators, representatives and executors and shall inure
to your benefit, and your successors and assigns, including each and every
holder of the Note.

         (e) This Guaranty may be executed by one or more of the parties hereto
on any number of separate counterparts and all of the counterparts taken
together shall constitute one and the same instrument.

         (f) This Guaranty constitutes the joint and several obligation of each
guarantor of the Obligations, including the undersigned, and shall be fully
binding upon and enforceable against any or all of such parties or persons and
their sole and separate estates. Neither the death nor release of any guarantor
of the Obligations shall affect or release the joint and several liability of
any other person or party. You may at your option enforce this Guaranty against
one or more or all of the guarantors of the Obligations; provided you shall not
be required to resort to enforcement against each and every guarantor of the
Obligations and the failure to proceed against or join each and every of the
guarantors of the Obligations shall not affect the joint and several liability
of each of the guarantors of the Obligations.

         (g) This Guaranty is intended by us as a final expression of our
agreement and is intended as a complete statement of the terms and conditions to
which we are bound.

     18. Waiver of Jury Trial.

     Our legal counsel has advised us that (a) there may be a constitutional
right to a jury trial in connection with any claim, dispute or lawsuit arising
out of this Guaranty, and (b) such constitutional right may be waived. After
consultation with our counsel (which has included our counsel's review of this
Guaranty), we believe that it is in our best interest in this commercial
transaction to waive such right. Accordingly, we hereby waive our right to a
jury trial and further agree that the best forum for hearing any claim, dispute
or lawsuit, if any, arising in connection with this Guaranty or our relationship
with you, shall be a court of competent jurisdiction sitting without a jury.

     WE GIVE THIS GUARANTY FREELY AND VOLUNTARILY TO YOU WITHOUT ANY DURESS OR
COERCION. WE HAVE CONSULTED WITH COUNSEL AND WE HAVE CAREFULLY AND COMPLETELY
READ ALL OF THE TERMS AND PROVISIONS OF THIS GUARANTY.

                                                                    Exhibit 10.3

                             SUBORDINATION AGREEMENT

     THIS SUBORDINATION AGREEMENT ("Agreement") is made as of the ______ day of
December, 2002, by and among GREENFIELD COMMERCIAL CREDIT, L.L.C., a Michigan
limited liability company ("Lender"), Diversified Corporate Resources, Inc., a
Texas corporation, and Datatek Corporation, a Delaware corporation, Julia L.
Wesley and Michael P. Connolly (collectively "Creditor").

                                    RECITALS

     A.   As of the date hereof, Borrower is indebted to Creditor on the Junior
Indebtedness (as defined below).

     B.   Borrower is now borrowing, or proposes from time to time to borrow,
from Lender and Creditor has requested Lender to loan to Borrower, up to Three
Million Five Hundred Thousand and 00/100 Dollars ($3,500,000.00), pursuant to a
Loan and Security Agreement between Borrower and Lender ("Loan Agreement"). All
amounts owing to Lender under the Loan Agreement, as amended from time to time
(including any amendment increasing the principal balance above $3,500,000.00),
shall be referred to herein as the "Senior Indebtedness." The Senior
Indebtedness is due on demand.

     C.   The Senior Indebtedness is secured by security interests, mortgages,
liens, pledges, assignments and encumbrances ("Security Interests") on all
assets of Borrower.

     NOW THEREFORE, in consideration of the premises and for value received and
as an inducement to Lender to extend credit and lend money to Borrower, it is
jointly and severally agreed by the parties hereto as follows:

     1.   Any and all indebtedness of the Borrower to Creditor now existing or
hereafter created (the "Junior Indebtedness"), and the payment thereof by the
Borrower, shall be and is hereby postponed and subordinated to the prior payment
and satisfaction in full of the Senior Indebtedness. As used in this Agreement,
the term "indebtedness" shall mean any and all indebtedness, liabilities, and
obligations of every kind, nature and description, owed to Creditor by the
Borrower, whether direct or indirect, absolute or contingent, whether now due
and owing, or which may hereafter, from time to time, be or become due and owing
whether heretofore or hereafter created or arising, including all indebtedness
evidenced by any promissory note or notes now or hereafter executed and
delivered by the Borrower to such creditor and any and all renewals, extensions,
modifications, notations, replacements or refinancings thereof, and including,
without limitation, reasonable attorney fees, costs, and expenses incurred by
such creditor in connection with the enforcement of this Agreement and any
promissory note or notes referenced herein as well as any other obligations of
the Borrower.

     2.   The Senior Indebtedness shall be indefeasibly paid in full and
discharged before the Borrower may make or before Creditor may require any
payment as to the Junior Indebtedness; provided, however, that Lender agrees
that so long as no Demand or Default (as defined in the Loan Agreement) has
occurred, the Borrower may pay (but not prepay) to Creditor:

          (a)  each scheduled interest payment; and,

          (b)  each scheduled principal payment, if after taking account of any
simultaneous payment of interest pursuant to 2(a) above and such scheduled
principal payment, Borrower would have borrowing availability under the Loan
Agreement of not less than $1,000,000.00,

<PAGE>

according to the terms of the Junior Indebtedness Documents (as defined below)
as set forth on Exhibit A attached hereto.

     3.   The Junior Indebtedness is now and shall at all times hereafter be
unsecured. Creditor agrees that so long as the Senior Indebtedness is
outstanding, Creditor shall have no right to receive casualty or business
interruption insurance proceeds or condemnation proceeds, nor shall it have any
right to participate in or consent to the settlement of such proceeds.

     4.   In the event Creditor receives payment from the Borrower in violation
of this Agreement, whether such payment is in cash or otherwise, Creditor shall
be liable and accountable to Lender for such payment, shall be deemed to have
received such payment for the use and benefit of Lender, shall not commingle the
such payment with any other funds and shall pay over and deliver such payment to
Lender immediately upon receipt, to be applied upon the indebtedness of the
Borrower to Lender if in cash, and if in form other than cash, then as the same
is converted into cash.

     5.   This subordination by Creditor of the Junior Indebtedness shall
survive and remain in full force and effect in the event of any administration
of the property or affairs of the Borrower arising from any assignment for the
benefit of creditors, bankruptcy, receivership, liquidation or other like
proceeding. In the event the property or affairs of the Borrower are so
administered, indebtedness of the Borrower to Lender shall include interest
accrued subsequent to the date of the commencement of such administration until
the Senior Indebtedness is indefeasibly paid in full.

     6.   This Agreement shall continue to be effective, or be reinstated, as
the case may be, if at any time any payment to Lender is rescinded or returned
by Lender upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Borrower, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar office for the
Borrower or any substantial part of its property, or otherwise, all as though
such payment(s) had not been made. Creditor agrees to remit to Lender any
payment(s) received by Creditor after said rescinded or returned payment is
originally made by Lender.

     7.   Creditor shall not, without Lender's prior consent, (i) take any
action to obtain a judgment against Borrower, (ii) commence or join with any
other creditor or creditors of the Borrower in commencing any bankruptcy,
reorganization, receivership or insolvency proceeding against the Borrower,
(iii) exercise any other rights or remedies it may have under the Junior
Indebtedness Documents (as defined below), the Uniform Commercial Code or any
other applicable law with respect to any of the Borrower's assets or (iv) take
or permit any action prejudicial to or inconsistent with Lender's priority
position over Creditor that is created by this Agreement.

     8.   In the event the Borrower defaults on its obligations to Lender and,
as a result, Lender undertakes to enforce its security interests and liens in
any of the Borrower's assets, Creditor agrees that Creditor will not hinder,
delay or otherwise prevent Lender from taking any and all action which Lender
deems necessary to enforce its security interests and liens in any of the
Borrower's assets and to realize thereon.

     9.   In the event that the Borrower shall make payment of the Junior
Indebtedness in violation of this Agreement, whether such payment be in cash or
otherwise, then and in such event Lender shall be entitled to all of its
remedies for default set forth in the Loan Agreement including the right, at its
option and without notice, to declare all indebtedness of the Borrower to Lender
to be immediately due and payable notwithstanding the terms and conditions of
any note or other evidence thereof to the contrary.

     10.  Creditor and the Borrower represent to Lender that the Junior
Indebtedness is evidenced by the promissory notes listed on Exhibit A attached
hereto (the "Creditor Notes") without any

                                       2

<PAGE>

counterclaim, defense or offset. Creditor and the Borrower further represent to
Lender that said Junior Indebtedness is not evidenced by any notes or negotiable
instruments, other than the Creditor Notes. To the extent any Junior
Indebtedness subordinated by this Agreement is hereafter evidenced by a note or
negotiable instrument (also a "Creditor Note"), Creditor agrees to promptly,
upon receipt, deliver a copy of same to Lender.

     11.  Creditor agrees to endorse all Creditor Notes substantially as
follows:

          "The indebtedness hereby evidenced has been subordinated in favor of
          Greenfield Commercial Credit, L.L.C. ("Lender") by Subordination
          Agreement dated December ______, 2002, to which reference is hereby
          made, to secure all indebtedness now or hereafter owing by Diversified
          Corporate Resources, Inc., a Texas corporation, to the Lender."

     12.  Creditor represents, warrants and covenants to Lender that:

          (a)  It has not relied and will not rely on any representations or
information of any nature made by or received from Lender relating to the
Borrower in deciding to execute this Agreement;

          (b)  As of the date hereof, the total amount of the Junior
Indebtedness is $_________;

          (c)  A true and correct description of each document evidencing the
Junior Indebtedness, including the Creditor Note(s), is listed on Exhibit A
hereto, a true and accurate copy of each such document, including any amendments
thereto, is attached to Exhibit A, and, as of the date hereof, no documents or
agreement evidencing or otherwise relating to any Junior Indebtedness (the
"Junior Indebtedness Documents") exist except as set forth on Exhibit A;

          (d)  The Junior Indebtedness is unsecured;

          (e)  Creditor is the lawful owner of the Junior Indebtedness free and
clear of all liens and encumbrances, and it has not subordinated, encumbered,
assigned or transferred, and agrees that it will not subordinate, encumber,
assign or transfer at any time while this Agreement remains in effect, any
right, claim or interest of any kind in or to the Junior Indebtedness. Any
subordination, assignment or transfer in violation of this subparagraph
12(d)shall be null and void; and

          (f)  Creditor has received all consents and approvals required in
order for it to execute and deliver this Agreement.

     13.  Lender may at any time or times, in its discretion, (i) renew, extend
or otherwise modify the rate of interest on, the time and/or terms of payment
of, and/or any other of the terms and provisions relative to the Senior
Indebtedness or any of the other provisions of the Loan Agreement, (ii) lend
additional monies, extend additional credit and make other financial
accommodations to or for the account of the Borrower, (iii) waive or release any
collateral or guaranties which may be held as security for all or any part of
the Senior Indebtedness, and/or (iv) renew, extend, modify, amend, supplement
and/or restate any and all of Lender's agreements with the Borrower, including
the Loan Agreement, in any manner, in each case, without necessity of consent
from Creditor and without impairing or affecting this Agreement or any of
Lender's rights hereunder. Creditor shall provide Lender with copies of any
modifications or amendments to the Junior Indebtedness Documents promptly upon
the execution thereof.

     14.  Creditor hereby waives any rights it has or may have in the future to

Creditor also waives any right to be subrogated to the Senior Indebtedness
unless and until the Senior Indebtedness is indefeasibly paid in full.

     15.  Creditor agrees that it will not at any time directly or indirectly
contest the validity, perfection, priority or enforceability of any lien,
security interest, encumbrance or claim granted to Lender in or on the assets of
the Borrower, and hereby agrees not to hinder Lender or take a position adverse
to Lender in the defense of any action contesting the validity, perfection,
priority or enforceability of any such liens, security interests, encumbrances
or claims. Creditor further agrees that the provisions of this Agreement shall
remain in full force and effect notwithstanding a successful challenge to the
validity, perfection, priority or enforceability of all or any of the Senior
Indebtedness or the liens and security interests securing the Senior
Indebtedness.

     16.  This Agreement and the subordinations, agreements and priorities set
forth herein shall remain in full force and effect and Lender may make
extensions of credit to the Borrower in reliance upon this Agreement, until the
Senior Indebtedness has been indefeasibly paid in full, regardless of whether
any party hereto in the future seeks to rescind, revoke, amend, terminate or
reform, by litigation or otherwise, any part or all of this Agreement or any of
such party's respective agreements with the Borrower; and, Lender may hereafter
continue to grant to the Borrower renewals or extensions of time, and may
otherwise proceed in its sole discretion in the enforcement of the Senior
Indebtedness until all of said sums shall have been indefeasibly paid in full,
without in any manner impairing, lessening, or invalidating the force and effect
of this Agreement.

     17.  This Agreement shall be binding upon the parties hereto and their
respective heirs, executors, administrators, successors and assigns.

     18.  No delay, forbearance, or omission by Lender in the exercise of any
right or power accruing to it upon any default in the performance hereof by the
other parties hereto, shall impair any such right or power or shall be construed
to be a waiver of any such default or acquiescence therein. This Agreement may
be modified, and any of Lender's rights hereunder waived, only by an Agreement
in writing signed by Lender.

     19.  Upon the request of Lender, the Borrower and Creditor shall execute
and deliver such further documents and do such other acts as Lender may
reasonably request in order to effect fully the purpose of this Agreement.
