                   ADDITIONAL TERMS OF THE SECURITY AGREEMENT

GENERALLY - This agreement secures this note and any other debt I have with you,
now or later. However, it will not secure other debts if you fail this security
agreement or if you fail to give any required notice of the right of rescission.
If property described in this agreement is located in another state, this
agreement may also, in some circumstances, be governed by the law of the state
in which the Property is located. All locations referenced to "this note" or
"this agreement" or "this loan" shall mean this Universal Note and Security
Agreement.

<PAGE>

OWNERSHIP AND DUTIES TOWARD PROPERTY: I represent that I own all of the
Property, or to the extent, this is a purchase money security interest, I will
acquire ownership of the Property with the proceeds of the loan. I will defend
it against any other claim. Your claim to the Property is ahead of the claims of
any other creditor. I agree to do whatever you require to protect the loan your
security interest and to keep your claim in the Property ahead of the claims of
other creditors. I will not do anything to harm your position.

I will keep books, records, and accounts about the Property and my business in
general. I will let you examine these records at any reasonable time. I will
prepare any report or accounting you request, which deals with the Property.

I will keep the Property in my possession and will keep it in good repair and
use it only for the purpose(s) described on page 1 of this written permission. I
represent that I am the original owner of the Property and, if I am not, that I
have provided you with a list of prior owners of the Property.

I will keep the Property at my address listed on page 1 of this agreement,
unless we agree I may keep it at another location. If the Property is to be used
in another state, I will give you a list of those states. I will not try to sell
the Property unless it is inventory or I receive your written permission to do
so. If I sell the Property I will have the payment made payable to the order of
you and me.

I will pay all taxes and charges on the Property as they become due. You have
the right of reasonable access in order to inspect the Property. I will
immediately inform you of any loss or damage to the Property.

If I fail to perform any of my duties under this security agreement, or any
mortgage, deed of trust, lien or other security interest, you may without notice
to me perform the duties or cause them to be performed. Your right to perform
for me shall not create an obligation to perform and your failure to perform
will not preclude you from exercising any of your other rights under the law or
this security agreement.

PURCHASE MONEY SECURITY INTEREST - For the sole purpose of determining the
extent of a purchase money security interest arising under this security
agreement: (a) payments on any non-purchase money loan also secured by this
agreement will not be deemed to apply to the Purchase Money Loan, and (b)
payments on the Purchase Money Loan will be deemed to apply first to the
non-purchase money portion of the loan, if any, and then to the purchase money
obligations in the order in which the items of collateral were acquired or if
acquired at the same time, in the order selected by you. No security interest
will be terminated by application of this formula. "Purchase Money Loan" means
any loan the proceeds of which, in whole or in part, are used to acquire any
collateral securing the loan and all extensions, renewals, consolidations and
refinancing of such loan.

PAYMENTS BY LENDER - You are authorized to pay, on my behalf, charges I am or
may become obligated to pay to preserve or protect the secured property (such as
property insurance premiums). You may treat those payments as advances and add
them to the unpaid principal under the note secured by this agreement or you may
demand immediate payment of the amount advanced. INSURANCE - I agree to buy
insurance on the Property against the risks and for the amounts you require and
to furnish you continuing proof of coverage. I will have the insurance company
name you as loss payee on any such policy. You may require added security if you
agree that insurance proceeds may be used to repair or replace the Property. I
will buy insurance from a firm licensed to do business in the state where the
property is located. The firm will be reasonably acceptable to you. The
insurance will remain in force until the Property is released from this
agreement. If I fail to buy or maintain the insurance (or fail to name you as
loss payee) you may purchase it yourself.
WARRANTIES AND REPRESENTATIONS - If this agreement includes accounts, I will not
settle any account for less than its full value without your written permission.
I will collect all accounts until you tell me otherwise. I will keep in trust
for you the proceeds from all the accounts and any goods which are returned to
me or which I take back. I will not mix them with any other property of mine. I
will deliver them to you at your request. If you ask me to pay you the full
price on any returned items or items retaken by myself, I will do so.
         If this agreement covers inventory, I will not dispose of it except in
my ordinary course of business at the fair market value for the Property, or at
a minimum price established between you and me.
         If this agreement covers farm products I will provide you, at your
request, a written list of the buyers, commission merchants, or selling agents
to or through whom I may sell my farm products. In addition to those parties
named on this written list, I authorize you to notify at your sole discretion
any additional parties regarding your security interest in my farm products. I
remain subject to all applicable penalties for selling my farm products in
violation of my agreement with you and the Food Security Act. In this paragraph
the terms farm products, buyers, commission merchants and selling agents have
the meanings given to the in the Federal Food Security Act of 1985.

<PAGE>

REMEDIES - I will be in default on this security agreement if I am in default on
any note this agreement secures or if I fail to keep any promise contained in
the terms of this agreement. If I default, you have all of the rights and
remedies provided in the note and under the Uniform Commercial Code. You may
required me to make the secured property available to you at a place which is
reasonably convenient. You may take possession of the secured property and sell
it as provided by law. The proceeds will be applied first to your expenses and
then to the debt. I agree that 10 days written notice sent to my last known
address by first class mail will be reasonable notice under the Uniform
Commercial Code. My current address is on page 1. I agree to inform you in
writing of any change of my address. You may demand immediate payment of the
debt(s) if the debtor is not a natural person and without your prior written
consent; (1) a beneficial interest in the debtor is sold or transferred, or (2)
there is a change in either the identity or number of members of a partnership,
or (3) there is a change in ownership of more than 25 percent of the voting
stock of a corporation.
FILING - A carbon, photographic or other reproduction of this security agreement
or the financing statement covering the Property described in this agreement may
be used as a financing statement where allowed by law. Where permitted by laws,
you may file a financing statement which does not contain my signature, covering
the Property secured by this agreement.

                          ADDITIONAL TERMS OF THE NOTE

DEFINITIONS - As used on pages 1, 2, and 3, "terms" means the terms that apply
to this load. "I", "me", or "my" means each Borrower who signs this note and
each other person or legal entity (including guarantors, endorsers, and
sureties) who agrees to pay this note (together referred to as "us"). "You" or
"your" means the Lender and its successors and assigns.
APPLICABLE LAW - The laws of the United States and, to the extent not
inconsistent therewith, the laws of the state of Alabama. Any term of this
agreement, which is contrary to applicable laws, will not be effective, unless
the law permits you and me to agree to such a variation. If any provision of
this agreement cannot be enforced according to its terms, this fact will not
affect the enforceability of the remainder of this agreement. No modification of
this note or any agreement securing this note is effective unless the
modification is in writing and signed by you and me. Time is of the essence in
this agreement.
PAYMENTS - Each payment of principal and interest I make on this note will first
reduce the amount I owe you for charges, which are neither interest nor
principal. The remainder of each payment will then reduce accrued unpaid
interest, and then unpaid principal. If you and I agree to a different
application of payments, we will describe our agreement on this note. I may
prepay a part of, or the entire balance of this loan without penalty, unless we
specify to the contrary on this note. Any partial prepayment will not excuse or
reduce any later scheduled payment until this note is paid in full (unless, when
I make the prepayment, you and I agree in writing to the contrary).
INTEREST - Interest accrues on the principal remaining unpaid from time to time,
until paid in full. If I receive the principal in more than one advance, each
advance will start to earn interest only when I receive the advance. The
interest rate in effect on this note at any given time will apply to the entire
principal sum outstanding at that time. Notwithstanding anything to the
contrary, I don not agree to pay and you do not intend to charge any rate of
interest that is higher than the maximum rate of interest you could charge under
applicable law for the extension of credit that is agreed to in this note
(either before or after maturity). If any notice of interest accrual is sent and
is in error, we mutually agree to correct it, and if you actually collect more
interest than allowed by law and this agreement, you agree to refund it to me.
INDEX RATE - The index will serve only as a device for setting the interest rate
on this note. You do not guarantee by selecting this index or the margin, that
the interest rate on this note will be the same rate you charge on any other
loans or class of loans you make to me or other borrowers.
POST MATURITY DATE - For purposes of deciding when the "Post Maturity Rate"
(shown on page 1) applies, the term "maturity" means the date of the last
scheduled payment indicated on page 1 of this note or the date you accelerate
payment on the note, whichever is earlier.
SINGLE ADVANCE LOAND - If this is a single advance loan, you and I expect that
you will make only one advance of principal. However, you may add other amounts
to the principal if you make any payments described in the "PAYMENTS BY LENDER"
paragraph herein.
MULTIPLE ADVANCE LOANS - If this is a multiple advance loan, you and I expect
that you will make more than one advance of principal. If this is closed end
credit, repaying a part of the principal will not entitle me to additional
credit.
SET-OFF - I agree that you may set off any amount due and payable under this
note against any right I have to receive money from you.

          "Right to receive money from you" means:

          (1)  any deposit account balance I have with you;
          (2)  any money owed to me on an item presented to you or in your
               possession for collection or exchange; and
          (3)  any repurchase agreement or other nondeposit obligation.

         "Any amount due and payable under this note" means the total amount of
which you are entitled to demand payment under the terms of this note at the
time you set off. This total includes any balance the due date for which you
properly accelerate under this note.
         If my right to receive money from you is also owned by someone who has
not agreed to pay this note, your right of set-off will apply to my interest in
the obligation and to any other amounts I could withdraw on my sole request or
endorsement. Your right of set-off does not apply to an account or other
obligation where my rights are only as a representative. It also does not apply
to any Individual Retirement Account or other tax-deferred retirement account.
         You will not be liable for the dishonor of any check when the dishonor
occurs because you set off this debt against any of my accounts. I agree to hold
you harmless from any such claims arising as a result of your exercise of your
right to set-off.
DEFAULT - I will be in default if any one or more of the following occur:

     (1)  I fail to make a payment on time or in the amount due; (2) I fail to
          keep the Property insured, if required; (3) I fail to pay, r keep any
          promise, on any debt or agreement I have with you; (4) any other
          creditor of mine attempts to collect any debt I owe him through court
          proceedings; (5) I die, am declared incompetent, make an assignment
          for the benefit of creditors, or become insolvent (either because my
          liabilities exceed my assets or I am unable to pay my debts as they
          become due); (6) I make any written statement or provide any financial
          information that is untrue or inaccurate at the time it was provided;
          (7) I do or fail to do something which causes you to believe you will
          have difficulty collecting the amount I owe you; (8) any collateral
          securing this note is used in a manner or for a purpose which
          threatens confiscation by a legal authority; (9) I change my name or
          assume an additional name without first notifying you before making
          such a change; (10) I fail to plant, cultivate and harvest crops in
          due season; (11) any loan proceeds are used for a purpose that will
          contribute to excessive erosion of highly erodible land or the
          conversion of wetlands to produce and agricultural commodity, as
          further explained 7 C.F.R. Part 1940, Subpart G, Exhibit M.

REMEDIES - If I am in default on this note you have, but are not limited to, the
following the following remedies:

     (1)  You may demand immediate payment of all I owe you under this note
          (principal, accrued unpaid interest and other accrued unpaid charges).
     (2)  You may set off this debt against any right I have to the payment of
          money from you, subject to the terms of the "SET-OFF" paragraph
          herein.
     (3)  You may demand security, additional security, or additional parties to
          be obligated to pay this note as a condition for not using any other
          remedy.
     (4)  You may refuse to make advances to me or allow purchases on credit by
          me.
     (5)  You may use any remedy you have under state or federal law.
     (6)  You may make use of any remedy given to you in any agreement securing
          this note.

     By selecting any one or more of these remedies you do not give up your
right to use later any other remedy. By waiving your right to declare an event
to be a default, you do not waive your right to consider later the event a
default if it continues or happens again.

COLLECTION COSTS AND ATTORNEYS' FEES - I agree to pay you all reasonable costs
you incur to collect this debt or realize on any security. This includes, if the
amount financed is more than $300.00 your reasonable attorneys' fees of up to
15% of the unpaid debt if you refer collection of the note to an attorney who is
not your salaried employee. This provision also shall apply if I file a petition
or any other claim for relief under any bankruptcy rule or laws of the United
States, or if such petition or other claim for relief is filed against me by
another.

WAIVER - I give up my rights to required you to do certain things.  I will not
require you to:

       (1) demand payment of amounts due (presentment)
       (2) obtain official certification of nonpayment (protest); or
       (3) give notice that amounts due have not been paid (notice of dishonor).

     I waive any defenses I have based on surety ship or impairment of
collateral to the extent permitted by law, I also waive all personal property
exemptions in the property securing this loan. OBLIGATIONS INDEPENDENT - I
understand that I must pay this note even if someone else has also agreed to pay
it (by, for example, signing this form or a separate guarantee or endorsement).
You may sue me alone, or anyone else who is obligated on this note, or any
number of us together, to collect this note. You may without notice release any
party to this agreement without releasing any other party. If you give up any of
your rights, with or without notice, it will not affect my duty to pay this
note. Any extension of new credit to any of us, or renewal of this note by all
or less than all of us will not release me from my duty to pay it. (Of course,
you are entitled to only one payment in full.) I agree that you may at your
option extend this note or the debt represented by this note, or any portion of
the note or debt, from time to time without limit or notice and for any term
without affecting my liability for payment of the note. I will not assign my
obligation under this agreement without your prior written approval. CREDIT
INFORMATION - I agree and authorize you to obtain credit information about me
from time to time (for example, by requesting a credit report) and to report to
others your credit experience with me (such as a credit reporting agency). I
agree to provide you, upon request, any financial statement or information you
may deem necessary. I warrant that the financial statements and information I
provide to you are or will be accurate, correct and complete.

SIGNATURES: I AGREE TO THE TERMS OF THIS NOTE (INCLUDING THOSE ON PAGES 1, 2,
AND 3). I have received a copy on today's date.

       Nothing in this Agreement is a commitment to make future loans or
       advances.

 SECURITY INTEREST. To secure the payment and performance of the Secured Debts,
     Debtor gives Secured Party a security interest in all of the Property

GENERAL PROVISIONS. Each Debtor's obligations under this Agreement are
independent of the obligations of any other Debtor. Secured Party may sue each
Debtor individually or together with any other Debtor. Secured Party may release
any part of the Property and Debtor will remain obligated under this Agreement.
The duties and benefits of this Agreement will bind the successors and assigns
of Debtor and Secured Party. No modification of this Agreement is effective
unless made in writing and signed by Debtor and Secured Party. Whenever used,
the plural includes the singular and the singular includes the plural. Time is
of the essence.
APPLICABLE LAW. This Agreement is governed by the laws of the state in
which Secured Party is located. In the event of a dispute, the exclusive forum,
venue, and place of jurisdiction will be the state in which Secured Party is
located, unless otherwise required by law. If any provision of this Agreement is
unenforceable by law, the unenforceable provision will be severed and the
remaining provisions will still be enforceable.
NAME AND LOCATION. Debtor's name indicated on page 1 is Debtor's exact
legal name. If Debtor is an individual, Debtor's address is Debtor's principal
residence. If Debtor is not an individual, Debtor's address is the location of
Debtor's chief executive offices or sole place of business. If Debtor is an
entity organized and registered under state law, Debtor has provided Debtor's
state of registration on page 1. Debtor will provide verification of
registration and location upon Secured Party's request. Debtor will provide
Secured Party with at least 30 days notice prior to any change in Debtor's name,
address, or state of organization or registration.
WARRANTIES AND REPRESENTATIONS. Debtor has the right, authority, and
power to enter into this Agreement. The execution and delivery of this Agreement
will not violate any agreement governing Debtor or Debtor's property, or to
which Debtor is a party. Debtor makes the following warranties and
representations which continue as long as this Agreement is in effect:
(1) Debtor is duly organized and validly existing in all jurisdictions in which
    Debtor does business;
(2) the execution and performance of the terms of this Agreement have been duly
    authorized, have received all necessary governmental approval, and will not
    violate any provision of law or order;
(3) other than previously disclosed to Secured Party, Debtor has not changed
    Debtor's name or principal place of business within the last 10 years and
    has not used any other trade or fictitious name; and
(4) Debtor does not and will not use any other name without Secured Party's
    prior written consent.
Debtor owns all of the Property, and Secured Party's claim to die
Property is ahead of the claims of any other creditor, except as otherwise
agreed and disclosed to Secured Party prior to any advance on the Secured Debts.
The Property has not been used for any purpose that would violate any laws or
subject the Property to forfeiture or seizure.
DUTIES TOWARD PROPERTY. Debtor will protect the Property and Secured
Party's interest against any competing claim. Except as otherwise agreed. Debtor
will keep the Property in Debtor's possession at the address indicated on page 1
of this Agreement. Debtor will keep the Property in good repair and use the
Property only for purposes specified on page 1. Debtor will not use the Property
in violation of any law and will pay all taxes and assessments levied or
assessed against the Property. Secured Party has the right of reasonable access
to inspect the Property, including the right to require Debtor to assemble and
make the Property available to Secured Party. Debtor will immediately notify
Secured Party of any loss or damage to the Property. Debtor will prepare and
keep books, records, and accounts about the Property and Debtor's business, to
which Debtor will allow Secured Party reasonable access. Debtor will not sell,
offer to sell, license, lease, or otherwise transfer or encumber the Property
without Secured Party's prior written consent. Any disposition of the Property
will violate Secured Party's rights, unless the Property is inventory sold in
the ordinary course of business at fair market value. If the Property includes
chattel paper or instruments, either as original collateral or as proceeds of
the Property, Debtor will record Secured Party's interest on die face of the
chattel paper or instruments. If the Property includes accounts, Debtor will not
settle any account for less than the full value, dispose of the accounts by
assignment, or make any material change in the terms of any account without
Secured Party's prior written consent. Debtor will collect all accounts in the
ordinary course of business, unless otherwise required by Secured Party. Debtor
will keep the proceeds of the accounts, and any goods returned to Debtor, in
trust for Secured Party and will not commingle the proceeds or returned goods
with any of Debtor's other property. Secured Parry has the right to require
Debtor to pay Secured Parry the full price on any returned items. Secured Party
may require account debtors to make payments under the accounts directly to
Secured Party. Debtor will deliver the accounts to Secured Party at Secured
Party's request. Debtor will give Secured Party all statements, reports,
certificates, lists of account debtors (showing names, addresses, and amounts
owing), invoices applicable to each account, and any other data pertaining to
the accounts as Secured Party requests.
If the Property includes farm products, Debtor will provide Secured
Party with a list of the buyers, commission merchants, and selling agents to or
through whom Debtor may sell the farm products. Debtor authorizes Secured Party
to notify any additional parties regarding Secured Party's interest in die
Debtor's farm products, unless prohibited by law. Debtor agrees to plant,
cultivate, and harvest crops in due season. Debtor will not use any loan
proceeds for a purpose that will contribute to excessive erosion of highly
erodible land or to the conversion of wetlands to produce an agricultural
commodity, as explained by federal law. If Debtor pledges the Property to
Secured Party (delivers the Property into the possession or control of Secured
Party or a designated third party), Debtor will, upon receipt, deliver any
proceeds and products of the Property to Secured Party. Debtor will provide
Secured Party with any notices, documents, financial statements, reports, and
other information relating to the Property Debtor receives as the owner of the
Property. PERFECTION OF SECURITY INTEREST. Debtor authorizes Secured Party to
file a financing statement covering the Property. Debtor will comply with,
facilitate, and otherwise assist Secured Party in connection with obtaining
possession or control over the Property for purposes of perfecting Secured
Party's interest under the Uniform Commercial Code.
INSURANCE. Debtor agrees to keep the Property insured against the risks
reasonably associated with the Property until the Property is released from this
Agreement. Debtor will maintain this insurance in the amounts Secured Party
requires. Debtor may choose the insurance company, subject to Secured Party's
approval, which will not be unreasonably withheld. Debtor will have the
insurance provider name Secured Party as loss payee on the insurance policy.
Debtor will give Secured Party and the insurance provider immediate notice of
any loss. Secured Party may apply the insurance proceeds toward the Secured
Debts. Secured Party may require additional security as a condition of
permitting any insurance proceeds to be used to repair or replace the Property.
If Secured Party acquires the Property in damaged condition, Debtor's rights to
any insurance policies and proceeds will pass to Secured Party to the extent of
the Secured Debts. Debtor will immediately notify Secured Party of the
cancellation or termination of insurance. If Debtor fails to keep die Property
insured, or fails to provide Secured Party with proof of insurance, Secured
Party may obtain insurance to protect Secured Party's interest in the Property.
The insurance may include coverages not originally required of Debtor, may be
written by a company other than one Debtor would choose, and may be written at a
higher rate than Debtor could obtain if Debtor purchased the insurance.
AUTHORITY TO PERFORM. Debtor authorizes Secured Party to do anything Secured
Party deems reasonably necessary to protect the Property and Secured Party's
interest in the Property. If Debtor fails to perform any of Debtor's duties
under this Agreement, Secured Party is authorized, without notice to Debtor, to
perform the duties or cause them to be performed. These authorizations include,
but are not limited to, permission to pay for the repair, maintenance, and
preservation of the Property and take any action to realize the value of the
Property. Secured Party's authority to perform for Debtor does not create an
obligation to perform, and Secured Party's failure to perform will not preclude
Secured Party from exercising any other rights under the law or this Agreement.
If Secured Party performs for Debtor, Secured Party will use reasonable care.
Reasonable care will not include any steps necessary to preserve rights against
prior parties or any duty to take action in connection with the management of
the Property. If Secured Party comes into possession of the Property, Secured
Party will preserve and protect the Property to the extent required by law.
Secured Party's duty of care with respect to the Property will be satisfied if
Secured Party exercises reasonable care in the safekeeping of the Property or in
the selection of a third parry in possession of the Property. Secured Party may
enforce the obligations of an account debtor or other person obligated on the
Property. Secured Party may exercise Debtor's rights with respect to the account
debtor's or other person's obligations to make payment or otherwise render
performance to Debtor, and enforce any security interest that secures such
obligations.
PURCHASE MONEY SECURITY INTEREST. If the Property includes items
purchased with the Secured Debts, the Property purchased with the Secured Debts
will remain subject to Secured Party's security interest until the Secured Debts
are paid in full. Payments on any non-purchase money loan also secured by this
Agreement will not be applied to the purchase money loan. Payments on the
purchase money loan will be applied first to the non-purchase money portion of
the loan, if any, and then to the purchase money portion in the order in which
the purchase money Property was acquired. If the purchase money Property was
acquired at the same time, payments will be applied in the order Secured Party
selects. No security interest will be terminated by application of this formula.
DEFAULT. Debtor will be in default if:
(1) Debtor (or Borrower, if not the same) fails to make a payment in full when
    due;
(2) Debtor fails to perform any condition or keep any covenant on this or any
    debt or agreement Debtor has with Secured Party;
(3) a default occurs under the terms of any instrument or agreement evidencing
    or pertaining to the Secured Debts;
(4) anything else happens that either causes Secured Party to reasonably believe
    that Secured Party will have difficulty in collecting the Secured Debts or
    significantly impairs the value of the Property.
REMEDIES. After Debtor defaults, and after Secured Party gives any
legally required notice and opportunity to cure the default, Secured Party may
at Secured Party's option do any one or more of the following:
(1)  make all or any part of the Secured Debts immediately due and accrue
     interest at the highest post-maturity interest rate;
(2)  require Debtor to gamer the Property and make it available to Secured Party
     in a reasonable fashion;
(3)  enter upon Debtor's premises and take possession of all or any part of
     Debtor's property for purposes of preserving the Property or its value and
     use and operate Debtor's property to protect Secured Party's interest, all
     without payment or compensation to Debtor;
(4)  use any remedy allowed by state or federal law, or provided in any
     agreement evidencing or pertaining to the Secured Debts.
If Secured Party repossesses the Property or enforces the obligations
of an account debtor, Secured Party may keep or dispose of the Property as
provided by law. Secured Party will apply the proceeds of any collection or
disposition first to Secured Party's expenses of enforcement, which includes
reasonable attorneys' fees and legal expenses to the extent not prohibited by
law, and men to the Secured Debts. Debtor (or Borrower, if not the same) will be
liable for the deficiency, if any. By choosing any one or more of these
remedies, Secured Party does not give up the right to use any other remedy.
Secured Party does not waive a default by not using a remedy.
WAIVER. Debtor waives all claims for damages caused by Secured Party's
acts or omissions where Secured Party acts in good faith.
NOTICE AND ADDITIONAL DOCUMENTS. Where notice is required, Debtor
agrees that 10 days prior written notice will be reasonable notice to Debtor
under the Uniform Commercial Code. Notice to one party is notice to all parties.
Debtor agrees to sign, deliver, and file any additional documents and
certifications Secured Party considers necessary to perfect, continue, or
preserve Debtor's obligations under this Agreement and to confirm Secured
Party's hen status on the Property.EXHIBIT 10.2

                      SECURITY AND SUBORDINATION AGREEMENT

          THIS SECURITY AGREEMENT (the "Agreement") is dated effective as of
 January 3, 2005, between DIGITAL FUSION, INC., a Delaware corporation (the
 "Debtor"), MICHAEL W. WICKS (the "Secured Party"), and FIRST COMMERCIAL BANK OF
 HUNTSVILLE ("FCB").

                                    ARTICLE 1
                                   BACKGROUND

          The Secured Party has agreed to make a loan to the Debtor as evidenced
 by a Convertible Promissory Note in the principal amount of $2,700,000, dated
 as of January 3, 2005 (the "Note").

          The Debtor has agreed to grant the Secured Party a security interest
 in property currently owned or later acquired by the Debtor to secure the
 prompt payment and performance of all liabilities, obligations, and
 indebtedness of the Debtor under the Note.

          The parties further acknowledge that the Debtor has entered into a
 lending transaction with FCB and has granted a security interest, in part, to
 all Accounts of the Debtor, which shall include the Accounts which are proceeds
 of the consulting contracts contained herein.

          The parties acknowledge that, unless and until an event of default
 shall have occurred hereunder, FCB shall have a first priority security
 interest on such Accounts regardless of whether they are proceeds of the
 consulting contracts of the customers, and the Secured Party hereby
 subordinates its security interest granted herein to FCB and Accounts, as more
 particularly set out herein.

                                    ARTICLE 2
                                     TERMS

          In consideration of the foregoing, the Secured Party and the Debtor
agree as follows:

          Section 2.1 Grant of Security Interest. To secure the due and punctual
 payment of the obligations under the Note and all extensions or renewals of the
 Note, including without limitation all costs and expenses (including reasonable
 attorneys' fees) incurred in collecting amounts due, the Debtor does hereby
 grant, bargain sell and convey to the Secured Party a security interest in all
 consulting contracts ("Consulting Contracts") between Summit Research
 Corporation ("Summit") and the customers listed on Exhibit "A" ("Customers"),
 whether such contracts are currently in effect or subsequently entered into
 between either Summit and such customers or Debtor and such Customers (all such
 Consulting Contracts are hereinafter collectively referred to as the
 "Collateral"), together with all proceeds (including insurance, contract and
 tort claims) and products of all of the foregoing Collateral.

          Section 2.2     Subordination of Grant of Security Interest.

                  (a) As a material inducement to FCB to lend money to Debtor
and to secure the due and punctual payment of the obligations due to FCB,
Secured Party agrees that, except as

<PAGE>

provided herein, so long as Debtor's indebtedness to FCB remains outstanding,
Secured Party's interest in Accounts (if any) as this term is defined herein
shall be subordinate to that of FCB's security interest in such Accounts.
Further, except as specifically provided herein, Secured Party agrees that so
long as Debtor's indebtedness to FCB remains outstanding, Secured Party will not
take any legal action for the collection of any part of Debtor's Accounts.
Except as set forth in paragraph (b) of this Section 2.2, the Secured Party
agrees that in the event it receives any payment relating to the Collateral it
will hold the same in trust for and immediately pay over to FCB any such
amounts.

         (b) Notwithstanding anything to the contrary contained herein, upon the
occurrence of any event of default hereunder or under the Note, Secured Party
shall notify FCB in writing of such default, and FCB shall have a period of
thirty (30) days from the date of receipt of such notice within which, at its
option, to completely cure such default by Debtor. Upon receipt by FCB of
written notice of the occurrence of an event of default under the Note and in
the event FCB elects not to cure such default as provided herein, FCB agrees
that it will immediately upon expiration of such thirty (30) day period take all
action necessary to release of record its prior security interest in the
Collateral. Secured Party agrees that, in the event FCB elects not to cure any
event of default, any monies it receives resulting from the Collateral and
related to any work performed thereunder prior to the date two (2) business days
after FCB receives written notice that an event of default has occurred (the
"Notification Date") under the Note shall be held for the benefit of FCB and
shall be immediately paid over to FCB. Likewise, FCB agrees that any monies it
receives resulting from the Collateral and related to any work performed
thereunder after the Notification Date shall be held for the benefit of Secured
Party and shall be immediately paid over to Secured Party Secured Party agrees
that in the event an election is made and contracts are reassigned to him, that
he will assist, through commercially reasonable efforts, in the collection of
accounts receivable which have been properly pledged to FCB, including, but not
limited to, providing follow-up service which would be required under said
contracts in order to allow said amounts to be collected and paid to FCB;
however, that nothing contained herein shall operate to make Secured Party a
guarantor of FCB's ability to recover any such payments.

         (c) All "Accounts" (as defined by the Alabama version of the Uniform
Commercial Code), includes accounts whether now owned or hereafter acquired by
Debtor and whether now existing or hereafter arising, and all proceeds of the
foregoing, whether cash or non-cash.

          Section 2.3 Representations and Warranties. The Debtor represents and
warrants as follows:

         (a) The execution, delivery and performance of this Agreement are
within the Debtor's corporate powers, have been duly authorized, are not in
contravention of law or the terms of the Debtor's charter or bylaws, or any
indenture, agreement, or undertaking to which the Debtor is a party or by which
it is bound.

         (b) On demand, the Debtor will execute and deliver to the Secured Party
such financing statements and other papers, and do all acts, as in the
reasonable judgment of the

                                       2

<PAGE>

 Secured Party may be necessary or appropriate to establish and maintain a valid
and prior security interest in the Collateral.

         (c) The Debtor will pay when due all taxes and assessments and will
discharge any liens on or affecting the Collateral or its use. If the Debtor
fails so to do, the Secured Party may at its option pay or discharge the same,
unless the Debtor is contesting such taxes, assessments, or liens, and the
Debtor will reimburse the Secured Party on demand for any such payment, and if
payment is delayed then with interest, which shall begin to accrue beginning
five business days after the date of demand at the highest rate allowable by
law.

         (d) No Adverse Liens. Except for any security interest specifically set
forth on an addendum attached hereto, and except for the security interest
granted hereby, the Debtor is or (with respect to Collateral not presently owned
by Debtor will be) the lawful owner of all Collateral free from any adverse
lien, security interest, or encumbrance, and shall have full right to pledge,
sell, assign, or transfer the same to Secured Party. Debtor will defend the
Collateral against all claims and demands of all persons at any time claiming
the same or any interest therein.

         (e) Financing Statements. No financing statement covering any
Collateral or any proceeds thereof is on file in any public office, except for
financing statements specifically set forth on an addendum attached hereto, if
any, and except for the financing statements executed by Debtor and Secured
Party. At the Secured Party's request, the Debtor will join with Secured Party
in executing one or more financing statements pursuant to the Code in form
satisfactory to the Secured Party, and will pay the cost of filing the same in
all public offices wherever filing is deemed by the Secured Party to be
necessary or desirable. The Debtor authorizes the Secured Party to prepare and
to file financing statements covering the Collateral signed only by the Secured
Party and to sign the Debtor's signature to such financing statements in
jurisdictions where Debtor's signature is required. The Debtor promises to pay
the Secured Party the fees incurred in filing the financing statements,
including but not limited to mortgage recording taxes payable in connection with
filings on fixtures, which fees shall become part of the Liabilities secured by
this Agreement.

         (f) Inspection of Collateral and Records. The Secured Party may examine
and inspect the Collateral and records and documents related to the Collateral
at any time, wherever located.

         (g) Assignment or Sale. Debtor, its agents, servants, or employees will
not sell, assign, or offer to sell or assign or otherwise transfer the
Collateral, either in whole or in part, or any interest therein without the
written consent of the Secured Party.

          Section 2.4 Default. The Debtor will be in default on the occurrence
 of any of the following events or conditions (hereafter called an "Event of
 Default"):

         (a) Any default by the Debtor under the Note;

         (b) The failure of Debtor to perform any of the agreements of the
Debtor contained in this Agreement within thirty (30) days of the date of
receipt by Debtor of written notice of such failure;

                                       3

<PAGE>

         (c) The filing of any petition under the Bankruptcy Code, or any
similar federal or state statute, by or against the Debtor, which action shall
not have been discharged within 60 days after filed;

         (d) The filing of an application for the appointment of a receiver for,
the making of a general assignment for the benefit of creditors by, or the
insolvency of the Debtor, which filing is not discharged within 60 days after
the date filed; or

         (e) The taking of possession of any substantial part of the property of
the Debtor at the instance of any governmental authority.

         Section 2.5 Remedies on Default. On occurrence of an Event of Default,
the Secured Party may, at any time after the Event of Default, declare all or
any of the obligations under the Note immediately due and payable. The Secured
Party will have, in addition to all its other rights and remedies, the rights
and remedies of a secured party under the Uniform Commercial Code. In exercising
its remedies, the Secured Party shall comply with all applicable requirements of
the Uniform Commercial Code, including the exercise of commercial reasonableness
in connection with any disposition of the Collateral. The remedies of the
Secured Party under this Agreement are cumulative, and the exercise of any one
or more of them shall not constitute a general election of remedies.
Notwithstanding the foregoing, in the event the gross revenue generated by the
Collateral for the twelve (12) month period prior to the date of any Event of
Default is less than $8,000,000, then the Secured Party's sole remedy for a
default under the Note, including the collection of any principal and interest
due thereunder, but excluding any fees, costs or expenses incurred in collecting
such amounts, shall be the foreclosure upon the Collateral. In the event the
gross revenue generated by the Collateral over such period exceeds $8,000,000,
then, in addition to any other remedies available to him, Secured Party shall
also have a claim directly against the Debtor for payment of any and all amounts
due under the Note or hereunder.

         Section 2.6 Waiver. No act, delay, omission, or course of dealing
between the Secured Party and the Debtor shall be a waiver of any of the Secured
Party's rights or remedies under this Agreement, and no waiver, change,
modification, or discharge in whole or in part of this Agreement or of any
obligation will be effective unless in a writing signed by the Secured Party. A
waiver by the Secured Party of any rights or remedies under the terms of this
Agreement or with respect to any obligation on any occasion will not be a bar to
the exercise of any right or remedy on any subsequent occasion. All rights and
remedies of the Secured Party hereunder are cumulative and may be exercised
singly or concurrently, and the exercise of any one or more of them will not be
a waiver of any other.

         Section 2.7 Power of Attorney. The Debtor appoints the Secured Party as
its attorney, with power to execute such documents on the Debtor's behalf and to
supply any omitted information and correct patent errors in any documents
executed by the Debtor or on the Debtor's behalf; to file financing statements
against the Debtor covering the Collateral; to sign the Debtor's name on public
records or on any assignment or transfer document necessary in order to transfer
ownership of or title to the Collateral to Secured Party; and to do all other
things the Secured Party deems necessary, appropriate or convenient, in his sole
discretion, to carry out this Agreement. The Debtor ratifies and approves all
acts of the attorney and neither the Secured

                                       4

<PAGE>

Party nor the attorney will be liable for any acts of commission or
omission, nor for any error of judgment or mistake of fact or law. This power
being coupled with an interest, is irrevocable so long as any amount under the
Note remains unpaid. Notwithstanding the foregoing, the Secured Party will not
exercise any rights contemplated by this paragraph unless an Event of Default
has occurred and the Debtor otherwise fails (following the request of the
Secured Party) to execute any such documents, supply any such information,
correct any such errors, sign the Debtor's name on any such financing statements
or do such other things as the Secured Party may deem necessary to carry out
this Agreement.

         Section 2.8 Assignment of Note. If at any time or times by sale,
assignment, negotiation, pledge, or otherwise, Secured Party transfers any or
all of the Note, such transfer shall, unless otherwise specified in writing,
carry with it Secured Party's rights and remedies under this Agreement with
respect to such Note transferred, and the transferee shall become vested with
such rights and remedies whether or not they are specifically referred to in the
transfer; provided, however, Secured Parties assignment of any of the Note to
Steven L. Thornton shall not include any of Secured Party's rights and remedies
under this Agreement. If and to the extent Secured Party retains any of the
Note, Secured Party shall continue to have the rights and remedies herein set
forth with respect thereto.

         Section 2.9 Notice. All notices, requests, demands, claims and other
communications under this Agreement shall be in writing, and sent (a) by
registered or certified mail, return receipt requested, postage prepaid, or (b)
by nationally recognized overnight courier, to the intended recipient as set
