OBLIGATIONS OF GRANTOR.  Grantor warrants and covenants to Lender as follows:

     Perfection of Security Interest. Grantor agrees to execute such financing
statement and to take whatever other actions are requested by Lender to perfect
and continue Lender's security interest in the Collateral. Upon request of
Lender, Grantor will deliver to Lender any and all of the documents evidencing
or constituting the Collateral, and Grantor will note Lender's interest upon any
and all chattel paper if not delivered to Lender for possession by Lender.
Grantor hereby appoints Lender as its irrevocable attorney-in-fact for the
purpose of executing any documents necessary to perfect or to continue the
security interest granted in this Agreement. Lender may at any time, and without
further authorization from Grantor, file a carbon, photographic or other
reproduction of any financing statement or of this Agreement for use as a
financing statement. Grantor will reimburse Lender for all expenses for the
perfection and the continuation of the perfection of Lender's security interest
in the Collateral. Grantor promptly will notify Lender before any change in
Grantor's name including any change to the assumed business names of Grantor.
This is a continuing Security Agreement and will continue in effect even though
all or any part of the Indebtedness is paid in full and even though for a period
of time Grantor may not be indebted to Lender.

     No Violations. The execution and delivery of this Agreement will not
violate any law or agreement governing Grantor or to which Grantor is a party,
and its certificate or articles of incorporation and bylaws do not prohibit any
term or condition of this Agreement.

     Enforceability of Collateral. To the extent the Collateral consists of
accounts, chattel paper, or general intangibles, the Collateral is enforceable
in accordance with its terms, is genuine, and complies with applicable laws
concerning form, content and manner of preparation and execution, and all
persons appearing to be obligated on the Collateral have authority and capacity
to contract and are in fact obligated as they appear to be on the Collateral.

     Location of the Collateral. Grantor, upon request of Lender, will deliver
to Lender in form satisfactory to Lender a schedule of real properties and
Collateral locations relating to Grantor's operations, including without
limitation the following: (a) all real property owned or being purchased by
Grantor; (b) all real property being rented or leased by Grantor; (c) all
storage facilities owned, rented, leased, or being used by Grantor; and (d) all
other properties where Collateral is or may be located. Except in the ordinary
course of its business, Grantor shall not remove the Collateral from its
existing locations without the prior written consent of Lender.

     Removal of Collateral. Grantor shall keep the Collateral (or to the extent
the Collateral consists of intangible property such as accounts, the records
concerning the Collateral) at Grantor's address shown above, or at such other
locations as are acceptable to Lender. Except in the ordinary course of its
business, including the sales of inventory, Grantor shall not remove the
Collateral from its existing locations without the prior written

<PAGE>

consent of Lender. To the extent that the Collateral consists of vehicles, or
other titled property, Grantor shall not take or permit any action which would
require application for certificates of title for the vehicles outside the State
of Texas, without the prior written consent of Lender.

     Transactions Involving Collateral. Except for inventory sold or accounts
collected in the ordinary course of Grantor's business, Grantor shall not sell,
offer to sell, or otherwise transfer or dispose of the Collateral. While Grantor
is not in default under this Agreement, Grantor may sell inventory, but only in
the ordinary course of its business and only to buyers who qualify as a buyer in
the ordinary course of business. A sale in the ordinary course of Grantor's
business does not include a transfer in partial or total satisfaction of a debt
or any bulk sale. Grantor shall not pledge, mortgage, encumber or otherwise
permit the Collateral to be subject to any lien, security interest, encumbrance,
or charge, other than the security interest provided for in this Agreement,
without the prior written consent of Lender. This includes security interests
even if junior in right to the security interests granted under this Agreement.
Unless waived by Lender, all proceeds from any disposition of the Collateral
(for whatever reason) shall be held in trust for Lender and shall not be
commingled with any other funds; provided however, this requirement shall not
constitute consent by Lender to any sale or other disposition. Upon receipt,
Grantor shall immediately deliver any such proceeds to Lender.

     Title. Grantor represents and warrants to Lender that it holds good and
marketable title to the Collateral, free and clear of all liens and encumbrances
except for the lien of this Agreement. No financing statement covering any of
the Collateral is on file in any public office other than those which reflect
the security interest created by this Agreement or to which Lender has
specifically consented. Grantor shall defend Lender's rights to the Collateral
against the claims and demands of all other persons.

     Collateral Schedules and Locations. Insofar as the Collateral consists of
inventory, Grantor shall deliver to Lender, as often as Lender shall require,
such lists, descriptions, and designations of such Collateral as Lender may
require to identify the nature, extent, and location of such Collateral. Such
information shall be submitted for Grantor and each of its subsidiaries or
related companies.

     Maintenance and Inspection of Collateral. Grantor shall maintain all
tangible Collateral in good condition and repair. Grantor will not commit or
permit damage to or destruction of the Collateral or any part of the Collateral.
Lender and its designated representatives and agents shall have the right at all
reasonable times to examine, inspect, and audit the Collateral wherever located.
Grantor shall immediately notify Lender of all cases involving the return,
rejection, repossession, loss or damage of or to any Collateral; of any request
for credit or adjustment or of any other dispute arising with respect to the
Collateral; and generally of all happenings and events affecting the Collateral
or the value or the amount of the Collateral.

     Taxes, Assessments and Liens. Grantor will pay when due all taxes,
assessments and liens upon the Collateral, its use or operation, upon this
Agreement, upon any promissory note or notes evidencing the Indebtedness, or
upon any of the other Related Documents. Grantor may withhold any such payment
or may elect to contest any lien if Grantor is in good faith conducting an
appropriate proceeding to contest the obligation to pay and so long as Lender's
interest in the Collateral is not jeopardized in Lender's

<PAGE>

sole opinion. If the Collateral is subjected to a lien which is not discharged
within fifteen (15) days, Grantor shall deposit with Lender cash, a sufficient
corporate surety bond or other security satisfactory to Lender in an amount
adequate to provide for the discharge of the lien plus any interest, costs,
attorneys' fees or other charges that could accrue as a result of foreclosure or
sale of the Collateral. In any contest Grantor shall defend itself and Lender
and shall satisfy any final adverse judgment before enforcement against the
Collateral. Grantor shall name Lender as an additional obligee under any surety
bond furnished in the contest proceedings.

     Compliance with Governmental Requirements. Grantor shall comply promptly
with all laws, ordinances, rules and regulations of all governmental
authorities, nor or hereafter in effect, applicable to the ownership,
production, disposition, or use of the Collateral. Grantor may contest in good
faith any such law, ordinance or regulation and withhold compliance during any
proceeding, including appropriate appeals, so long as Lender's interest in the
Collateral, in Lender's opinion, is not jeopardized.

     Hazardous Substances. Grantor represents and warrants that the Collateral
never has been, and never will be so long as this Agreement remains a lien on
the Collateral, used for the generation, manufacture, storage, transportation,
treatment, disposal, release or threatened release of any hazardous waste or
substance, as those terms are defined in the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980, as amended, 42 U.S.C. Section
9601, et seq. ("CERCLA"), the Superfund Amendments and Reauthorization Act of
1986, Pub. L. No. 99-499 ("SARA"), the Hazardous Materials Transportation Act,
49 U.S.C. Section 1801, et seq., the Resource Conversation and Recovery Act, 42
U.S.C. Section 6901, et seq., or other applicable state or Federal laws, rules,
or regulations adopted pursuant to any of the foregoing. The terms "hazardous
waste" and "hazardous substance" shall also include, without limitation,
petroleum and petroleum by-products or any fraction thereof and asbestos. The
representations and warranties contained herein are based on Grantor's due
diligence in investigating the Collateral for hazardous wastes and substances.
Grantor hereby (a) releases and waives any future claims against Lender for
indemnity or contribution in the event Grantor becomes liable for cleanup or
other costs under any such laws, and (b) agrees to indemnify and hold harmless
Lender against any and all claims and losses resulting from a breach of this
provision of this Agreement. This obligation to indemnify shall survive the
payment of the Indebtedness and the satisfaction of this Agreement.

     Maintenance of Casualty Insurance. Grantor shall procure and maintain all
risks insurance, including without limitation fire, theft and liability coverage
together with such other insurance as Lender may require with respect to the
Collateral, in form, amounts, coverages and basis reasonably acceptable to
Lender. GRANTOR MAY FURNISH THE REQUIRED INSURANCE WHETHER THROUGH EXISTING
POLICIES OWNED OR CONTROLLED BY GRANTOR OR THROUGH EQUIVALENT INSURANCE FROM ANY
INSURANCE COMPANY AUTHORIZED TO TRANSACT BUSINESS IN THE STATE OF TEXAS. If
Grantor fails to provide any required insurance or fails to continue such
insurance in force, Lender may, but shall not be required to, do so at Grantor's
expense, and the cost of the insurance will be added to the Indebtedness. If any
such insurance is procured by Lender at a rate or charge not fixed or approved
by the State Board of Insurance, Grantor will be so notified, and Grantor will
have the option for five (5) days of furnishing equivalent insurance through any
insurer authorized to transact business in Texas. Grantor, upon request of
Lender, will deliver to Lender from time to time the policies or certificates of

<PAGE>

insurance in form satisfactory to Lender, including stipulations that coverages
will not be cancelled or diminished without at least (10) days' prior written
notice to Lender and not including any disclaimer of the insurer's liability for
failure to give such a notice. Each insurance policy also shall include an
endorsement providing that coverage in favor of Lender will not be impaired in
any way by any act, omission or default of Grantor or any other person. In
connection with all policies covering assets in which Lender holds or is offered
a security interest, Grantor will provide Lender with such loss payable or other
endorsements as Lender may require. If Grantor at any time fails to obtain or
maintain any insurance as required under this Agreement, Lender may (but shall
not be obligated to) obtain such insurance as Lender deems appropriate,
including if it so chooses "single interest insurance," which will cover only
Lender's interest in the Collateral.

     Application of Insurance Proceeds. Grantor shall promptly notify Lender of
any loss or damage to the Collateral. Lender may make proof of loss if Grantor
fails to do so within fifteen (15) days of the casualty. All proceeds of any
insurance on the Collateral, including accrued proceeds thereon, shall be held
by Lender as part of the Collateral. If Lender consents to repair or replacement
of the damaged or destroyed Collateral, Lender shall, upon satisfactory proof of
expenditure, pay or reimburse Grantor from the proceeds for the reasonable cost
of repair or restoration. If Lender does not consent to repair or replacement of
the Collaeral, Lender shall retain a sufficient amount of the proceeds to pay
all of the Indebtedness, and shall pay the balance to Grantor. Any proceeds
which have not been disbursed within six (6) months after their receipt and
which Grantor has not committed to the repair or restoration of the Collateral
shall be used to prepay the Indebtedness.

     Insurance Reserves. Lender may require Grantor to maintain with Lender
reserves for payment of insurance premiums, which reserves shall be created by
monthly payments from Grantor of a sum estimated by Lender to be sufficient to
produce, at least fifteen (15) days before the premium due date, amounts at
least equal to the insurance premiums to be paid. If fifteen (15) days before
payment is due, the reserve funds are insufficient, Grantor shall upon demand
pay any deficiency to Lender. The reserve funds shall be held by Lender as a
general deposit and shall constitute a non-interest-bearing account which Lender
may satisfy by payment of the insurance premiums required to be paid by Grantor
as they become due. Lender does not hold the reserve funds in trust for Grantor,
and Lender is not the agent of Grantor for payment of the insurance premiums
required to be paid by Grantor. The responsibility for the payment of premiums
shall remain Grantor's sole responsibility.

     Insurance Reports. Grantor, upon request of Lender, shall furnish to Lender
reports on each existing policy of insurance showing such information as Lender
may reasonably request including the following: (1) the name of the insurer; (b)
the risks insured; (c) the amount of the policy; (d) the property insured; (c)
the then current value on the basis of which insurance has been obtained and the
manner of determining that value; and (f) the expiration date of the policy. In
addition, grantor shall upon request by Lender (however not more often than
annually) have an independent appraiser satisfactory to Lender determine, as
applicable, the cash value or replacement cost of the Collateral.

Grantor's Right to Possession. Until default, Grantor may have possession of the
tangible personal property and beneficial use of all the Collateral and

<PAGE>

may use it in any lawful manner not inconsistent with this Agreement or the
Related Documents, provided that Grantor's right to possession and beneficial
use shall not apply to any Collateral where possession of the Collateral by
Lender is required by law to perfect Lender's security interest in such
Collateral. If Lender at any time has possession of any Collateral, whether
before or after an Event of Default, Lender shall be deemed to have exercised
reasonable care in the custody and preservation of the Collateral. If Lender
takes such action for that purpose as Grantor shall request or as Lender, in
Lender's sole discretion, shall deem appropriate under the circumstances, but
failure to honor any request by Grantor shall not of itself be deemed to be a
failure to exercise reasonable care. Lender shall not be required to take any
steps necessary to preserve any rights in the Collateral against prior parties,
nor to protect, preserve or maintain any security interest given to secure the
Indebtedness.

Expenditures by Lender. If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without limitation
all taxes, liens, security interests, encumbrances, and other claims, at any
time levied or placed on the Collateral. Lender also may (but shall not be
obligated to) pay all costs for insuring, maintaining and preserving the
Collateral. All such expenditures incurred or paid by Lender for such purposes
will then bear interest at the Note rate from the date incurred or paid by
Lender to the date of repayment by Grantor. All such expenses shall become a
part of the Indebtedness and, at Lender's option, will (a) be payable on demand,
(b) be added to the balance of the Note and be apportioned among and be payable
with any installment payments to become due during either (i) the term of any
applicable insurance policy or (ii) the remaining term of the Note, or (c) be
treated as a balloon payment which will be due and payable at the Note's
maturity. This Agreement also will secure payment of these amounts. Such right
shall be in addition to all other rights and remedies to which Lender may be
entitled upon the occurrence of an Event of Default.

Events of Default. Each of the following shall constitute an Event of Default
under this Agreement:

     Default on Indebtedness. Failure of Grantor to make any payment when due on
the Indebtedness.

     Other Defaults. Failure of Grantor to comply with or to perform any other
term, obligation, covenant or condition contained in this Agreement of in any of
the Related Documents or in any other agreement between Lender and Grantor.

     Default in Favor of Third Parties. Should Borrower or any Grantor default
under any loan, extension of credit, security agreement, purchase or sales
agreement, or any other agreement, in favor of any other creditor or person that
may materially affect any of Borrower's property or Borrower's or Grantor's
ability to repay the Loans or perform their respective obligations under this
Agreement or any of the Related Documents.

     False Statements. Any warranty, representation or statement made or
furnished to Lender by or on behalf of Grantor under this Agreement, the Note or
the Related Documents is false or misleading in any material respect, either now
or at the time made or furnished.

<PAGE>

     Defective Collateralization. This Agreement or any of the Related Documents
ceases to be in full force and effect (including failure of any collateral
documents to create a valid and perfected security interest or lien) at any time
and for any reason.

     Insolvency. The dissolution or termination of Grantor's existence as a
going business, the insolvency of Grantor, the appointment of a receiver for any
part of Grantor's property, any assignment for the benefit of creditors, and
type of creditor workout, or the commencement of any proceeding under any
bankruptcy or insolvency laws by or against Grantor.

     Creditor or Forfeiture Proceedings. Commencement of foreclosure or
forfeiture proceedings, whether by judicial proceeding, self-help, repossession
or any other method, by any Creditor of Grantor or by any governmental agency
against the Collateral or any other collateral securing the Indebtedness. This
includes a garnishment of any of Grantor's deposit accounts with Lender.

     Events Affecting Guarantor. Any of the preceding events occurs with respect
to any Guarantor of any of the Indebtedness or such Guarantor dies or becomes
incompetent.

     Adverse Change. A material adverse change occurs in Grantor's financial
condition, or Lender believes the prospect of payment or performance of the
Indebtedness is impaired.

     Insecurity.  Lender, in good faith, deems itself insecure.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the Texas Uniform Commercial Code. In addition and without
limitation, Lender may exercise any one or more of the following rights and
remedies:

     Accelerate Indebtedness. Lender may declare the entire Indebtedness
immediately due and payable, without notice.

     Assemble Collateral. Lender may require Grantor to deliver to Lender all or
any portion of the Collateral and any and all certificates of title and other
documents relating to the Collateral. Lender may require Grantor to assemble the
Collateral and make it available to Lender at a place to be designated by
Lender. Lender also shall have full power to enter, provided Lender does so
without a breach of the peace or a trespass, upon the property of Grantor to
take possession of and remove the Collateral. If the Collateral contains other
goods not covered by this Agreement at the time of the repossession, Grantor
agrees Lender may take such other goods, provided that Lender makes reasonable
efforts to return them to Grantor after repossession.

     Sell the Collateral. Lender shall have full power to sell, lease, transfer,
or otherwise deal with the Collateral or proceeds thereof in its own name or
that of Grantor. Lender may sell the Collateral at public auction or private
sale. Unless the Collateral threatens to decline speedily in value or is of a
type customarily sold on a recognized market, Lender will give Grantor
reasonable notice of the time after which any private sale or any other intended
disposition of the Collateral is to be made. The requirements of reasonable
notice shall be met if such notice is given at least ten (10) days before the
time of the sale or disposition. All expenses

<PAGE>

relating to the disposition of the Collateral, including without limitation the
expenses of retaking, holding, insuring, preparing for sale and selling the
Collateral, shall become a part of the Indebtedness secured by this Agreement
and shall be payable on demand, with interest at the Note rate from date of
expenditure until repaid.

     Appoint Receiver. To the extent permitted by applicable law, Lender shall
have the following rights and remedies regarding the appointment of a receiver:
(a) Lender may have a receiver appointed as a matter of right, (b) the receiver
may be an employee of Lender and may serve without bond, and (c) all fees of the
receiver and his or her attorney shall become part of the Indebtedness secured
by this Agreement and shall be payable on demand, with interest at the Note rate
from date of expenditure until repaid.

     Collect Revenues, Apply Accounts. Lender, either itself or through a
receiver, may collect the payments, rents, income, and revenues from the
Collateral. Lender may at any time in its discretion transfer any Collateral
into its own name or that of its nominee and receive the payments, rents,
income, and revenues therefrom and hold the same as security for the
Indebtedness or apply it to payment of the Indebtedness in such order of
preference as Lender may determine. Insofar as the Collateral consists of
accounts, general intangibles, insurance policies, instruments, chattel paper,
choses in action, or similar property, Lender may demand, collect, receipt for,
settle, compromise, adjust, sue for, foreclose, or realize on the Collateral as
Lender may determine, whether or not Indebtedness or Collateral is then due. For
these purposes, Lender may, on behalf of and in the name of Grantor, receive,
open and dispose of mail addressed to Grantor; change any address to which mail
and payments are to be sent; and endorse notes, checks, drafts, money orders,
documents of title, instruments and items pertaining to payment, shipment, or
storage of any Collateral. To facilitate collection, Lender may notify account
debtors and obligors on any Collateral to make payments directly to Lender.

     Obtain Deficiency. If Lender chooses to sell any or all of the Collateral,
Lender may obtain a judgment against Grantor for any deficiency remaining on the
Indebtedness due to Lender after application of all amounts received from the
exercise of the rights provided in this Agreement. Grantor shall be liable for a
deficiency even if the transaction described in this subsection is a sale of
accounts or chattel paper.

     Other Rights and Remedies. Lender shall have all the rights and remedies of
a secured creditor under the provisions of the Uniform Commercial Code, as may
be amended from time to time. In addition, Lender shall have and may exercise
any or all other rights and remedies it may have available at law, in equity, or
otherwise.

     Cumulative Remedies. All of Lender's rights and remedies, whether evidenced
by this Agreement or the Related Documents or by any other writing, shall be
cumulative and may be exercised singularly or concurrently. Election by Lender
to pursue any remedy shall not exclude pursuit of any other remedy, and an
election to make expenditures or to take action to perform an obligation of
Grantor under this Agreement, after Grantor's failure to perform, shall not
affect Lender's right to declare a default and to exercise its remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Agreement:

     Severability. If a court of competent jurisdiction finds any provision of
this Agreement to be invalid or unenforceable as to any person or circumstance,
such finding shall not render that provision invalid or unenforceable as to any
other persons or circumstances. If feasible, any such offending provision shall
be deemed to be modified to be within the limits of enforceability or validity;
however, if the offending provision cannot be so modified, it shall be stricken
and all other provisions of this Agreement in all other respects shall remain
valid and enforceable.

     Successor Interests. Subject to the limitations set forth above on transfer
of the Collateral, this Agreement shall be binding upon and inure to the benefit
of the parties, their successors and assigns.

     Waiver. Lender shall not be deemed to have waived any rights under this
Agreement unless such waiver is given in writing and signed by Lender. No delay
or omission on the part of Lender in exercising any right shall operate as a
waiver of such right or any other right. A waiver by Lender of a provision of
this Agreement shall not prejudice or constitute a waiver of Lender's right
otherwise to demand strict compliance with that provision or any other provision
of this Agreement. No prior waiver by lender, nor any course of dealing between
Lender and Grantor, shall constitute a waiver of any of Lender's rights or of
any of Grantor's obligations as to any future transactions. Whenever the consent
of Lender is required under this Agreement, the granting of such consent by
Lender in any instance shall not constitute continuing consent to subsequent
instances where such consent is required and in all cases such consent may be
granted or withheld in the sole discretion of Lender.

        Re:  GlobalSCAPE, Inc. 1998 Stock Option Plan (the "998 Stock Option

Dear [NAME]:

under which GlobalSCAPE granted you an option to purchase [AMOUNT] shares of
GlobalSCAPE common stock for $0.10 per share under the terms of the 1998 Stock

        On February 8, 2000 you and GlobalSCAPE signed a letter under which

        Effective May 8, 2000 GlobalSCAPE completed  a stock split of its
common stock.

        In consideration for your execution of the Release and Indemnity
Agreement dated December 19, 2000, GlobalSCAPE has reinstated your Option, and
has adjusted the number of shares subject to your option to [AMOUNT] with an
exercise price of $0.0132 per share, to vest in thirds on the same schedule as
stated in the [DATE] letter, to wit:

        [AMOUNT]  vesting on [DATE]
        [AMOUNT]  vesting on [DATE]
        [AMOUNT]  vesting on [DATE]

                                        Sincerely,

Agreed:                                 GlobalSCAPE, Inc.
