                  (a) EXISTING DEBT. As of the date of this Agreement, the
         outstanding principal balance of the indebtedness under the Original
         Loan Documents is $7,509,582.15 and the accrued and unpaid interest
         thereunder is $1,243,665.18 (the "Existing Debt"). Borrower and Lender
         agree to allocate (i) $600,000.00 of such existing indebtedness to the
         Revolving Credit Facility (as defined below), (ii) $6,909,582.15 to the
         Term Loan (as defined below), and (iii) 1,243,665.18 to accrued and
         unpaid interest (the "Accrued Interest"). As of even date herewith, the
         balance of the Loans is $1,100,000.00. Borrower hereby acknowledges and
         agrees that no right of offset, defense, counterclaim, claim, causes of
         action or objection in favor of Borrower against Lender exists arising
         out of or with respect to any of the Existing Debt, the Accrued
         Interest, the Original Loan Documents, or with respect to any other
         documents or instruments now or heretofore evidencing, securing or in
         any way relating to any of the foregoing, and Borrower does hereby
         expressly waive, release and relinquish any and all such defenses,
         setoffs, claims, counterclaims and causes of action, if any, against
         Lender relating to the Existing Debt, the Accrued Interest or the
         Original Loan Documents.

                  (b) REVOLVING CREDIT FACILITY. Subject to the terms and
         conditions set forth in this Agreement and the other Loan Documents,
         Lender hereby agrees to lend to Borrower an aggregate sum not to exceed
         $2,000,000.00 (the "Revolving Credit Facility"), on a revolving basis
         from time to time during the period commencing on the date hereof and
         continuing until the earlier of (i) written demand for payment, (ii)
         the acceleration of the Indebtedness pursuant to the terms of this
         Agreement; or (iii) December 31, 2004 (the "Revolving Maturity Date").
         Provided that no Event of Default shall have occurred and be
         continuing, Lender will automatically renew the Revolving Credit
         Facility for a period of one (1) year from December 1, 2004 and for
         successive one year periods thereafter (but in no event beyond December
         31, 2006) unless Lender notifies Borrower within that the Revolving
         Credit Facility will not be renewed within thirty (30) days prior to
         such renewal date. If at any time the sum of the aggregate principal
         amount of Loans outstanding hereunder exceeds the Credit Facility (an
         "Overadvance"), Borrower shall immediately repay the amount of such
         Overadvance plus all accrued and unpaid interest thereon.
         Notwithstanding anything contained herein to the contrary, an
         Overadvance shall be considered a Loan and shall bear interest as such
         and be secured by this Agreement. Subject to the terms and conditions
         hereof, Borrower may borrow, repay and reborrow the Loans under the
         Revolving Credit Facility. All advances under this Agreement shall be
         collectively called the "Loans." Lender reserves the right to require
         Borrower to give Lender not less than one (1) Business Day prior notice
         of each Loan, specifying (i) the aggregate amount of such Loan, (ii)
         the requested date of such advance, and (ii) the purpose for such Loan.
         All Loans shall be in the sole discretion of Lender.

                  (c) TERM LOAN. Subject to the terms and conditions set forth
         in this Agreement and the other Loan Documents, Lender agrees to make
         available to Borrower a term loan credit facility (the "Term Loan")
         commencing on the date hereof and until the earlier of (i) the
         acceleration of the Indebtedness pursuant to the terms of this
         Agreement; or (ii) December 31, 2006 (the "Term Maturity Date") in a
         single advance and in an aggregate amount not to exceed $6,909,582.25.
         Borrower may not reborrow any sums prepaid under the Term Loan.

                  (d) MANDATORY PREPAYMENT OF TERM LOAN. Commencing on December
         31, 2003, within sixty (60) days after December 31 and June 30 of each
         calendar year (each such date, being a "Measuring Date"), Borrower
         shall prepay the Term Loan in an amount equal to (i) twenty-five
         percent (25%) of the Excess Cash Flow earned during the six (6) month
         period immediately preceding the Measuring Date, less (ii) the amount
         of any voluntary prepayments of the Term Loan during such prior three
         month period. All such prepayments shall be applied to payments due
         under the Term Loan in the inverse order of maturity.

                  (e) MANDATORY PREPAYMENT OF LOANS. Borrower shall prepay the
         Loans in an amount equal to $1,100,000 from the net proceeds of (i) any
         loan from a third party to Borrower or any subsidiary of Borrower, or
         (ii) the proceeds from any equity offering by Borrower or any
         subsidiary of Borrower.

                  (f) ACCRUED INTEREST. The Accrued Interest shall be paid in
         thirty-three (33) equal consecutive monthly installments commencing on
         April 30, 2004 and continuing on the last Business Day of each calendar
         month thereafter, with a final payment being made on the Term Maturity
         Date.

         3. PROMISSORY NOTES. The Revolving Credit Facility shall be evidenced
by a promissory note (such promissory note in the form of Exhibit B attached
hereto, together with any amendments, modifications, replacements,
substitutions, restatements, renewals, extensions and increases thereof, the
"Revolving Credit Note") duly executed by Borrower and payable to the order of
Lender, in form and substance acceptable to Lender. Interest on the Revolving
Credit Note shall accrue at the rate set forth therein. The principal of and
interest on the Revolving Credit Note shall be due and payable in accordance
with the terms and conditions set forth in the Revolving Credit Note and in this
Agreement. The Term Loan shall be evidenced by a promissory note (such
promissory note in the form of Exhibit C attached hereto, together with any
amendments, modifications, replacements, substitutions, restatements, renewals,
extensions and increases thereof, the "Term Note") duly executed by Borrower and
payable to the order of Lender, in form and substance acceptable to Lender.
Interest on the Term Note shall accrue at the rate set forth therein. The
principal of and interest on the Term Note shall be due and payable in
accordance with the terms and conditions set forth in the Term Note and in this
Agreement.

         4. COLLATERAL. As collateral and security for the Indebtedness,
Borrower hereby grants to Lender, its successors and assigns, a first priority
lien and security interest in and to the Collateral.

         5. REPRESENTATIONS AND WARRANTIES. Borrower hereby represents and
warrants, and upon each request for a Loan under the Revolving Credit Facility
or for the Term Loan represents and warrants to Lender as follows:

                  (a) EXISTENCE. Borrower is (i) duly organized, validly
         existing and in good standing under the laws of the State of Delaware,
         and (ii) duly qualified and licensed in all other states and
         jurisdictions where it is doing business, except where the failure to
         be so qualified or licensed would not (A) have a material adverse
         effect on Borrower, or (B) effect the enforceability of the lien
         granted Lender on the Collateral. Borrower has all requisite power and
         authority to execute and deliver the Loan Documents.

LOAN AND SECURITY AGREEMENT  - Page  6

<PAGE>

                  (b) BINDING OBLIGATIONS. The execution, delivery, and
         performance of the Loan Documents by Borrower have been duly authorized
         by all necessary action by Borrower, and constitute legal, valid and
         binding obligations of Borrower, enforceable in accordance with their
         respective terms, except as limited by bankruptcy, insolvency or
         similar laws of general application relating to the enforcement of
         creditors' rights and except to the extent specific remedies may
         generally be limited by equitable principles.

                  (c) NO CONSENT. The execution, delivery and performance of the
         Loan Documents, and the consummation of the transactions contemplated
         thereby, do not (i) conflict with, result in a violation of, or
         constitute a default under (1) any provision of its organizational
         document or other instrument binding upon Borrower, (2) any law,
         governmental regulation, court decree or order applicable to Borrower,
         or (3) any agreement, judgment, license, order or permit applicable to
         or binding upon Borrower, (ii) require the consent, approval or
         authorization of any third party, or (iii) result in or require the
         creation of any lien, charge or encumbrance upon any assets or
         properties of Borrower or of any person except as may be expressly
         contemplated in the Loan Documents.

                  (d) FINANCIAL CONDITION. Each financial statement of Borrower
         supplied to the Lender truly discloses and fairly presents Borrower's
         financial condition as of the date of each such statement. There has
         been no material adverse change in such financial condition or results
         of operations of Borrower subsequent to the date of the most recent
         financial statement supplied to the Lender.

                  (e) LITIGATION. There are no actions, suits or proceedings,
         pending or, to the knowledge of Borrower, threatened against or
         affecting Borrower, or the assets or properties of Borrower, before any
         court or governmental department, commission or board, which, if
         determined adversely, would have a material adverse effect on the
         financial condition, properties, or operations of Borrower.

                  (f) TAXES; GOVERNMENTAL CHARGES. Borrower has filed all
         federal, state and local tax reports and returns required by any law or
         regulation to be filed by it and has either duly paid all taxes, duties
         and charges indicated due on the basis of such returns and reports, or
         made adequate provision for the payment thereof, and the assessment of
         any material amount of additional taxes in excess of those paid and
         reported is not reasonably expected.

                  (g) OWNERSHIP AND LIENS. Borrower has good and marketable
         title to the Collateral free and clear of all liens, security
         interests, encumbrances or adverse claims, (other than the Permitted
         Liens). To Borrower's knowledge, no dispute, right of setoff,
         counterclaim or defense exists with respect to all or any part of the
         Collateral. Borrower has not executed any other security agreement
         currently affecting the Collateral and no effective financing statement
         or other instrument similar in effect covering all or any part of the
         Collateral is on file in any recording office.

                  (h) SECURITY INTEREST. Borrower has and will have at all times
         full right, power and authority to grant a security interest in the
         Collateral to Lender in the manner provided herein, free and clear of
         any lien, security interest or other charge or

         encumbrance other than for the Permitted Liens. This Agreement creates
         a legal, valid and binding security interest in favor of Lender in the
         Collateral securing the Indebtedness. Possession by Lender of certain
         types of Collateral from time to time or the filing of the financing
         statements delivered prior hereto or concurrently herewith by Borrower
         to Lender will perfect and establish the first priority of Lender's
         security interest hereunder in the Collateral other than for the
         Permitted Liens.

                  (i) LOCATION. Borrower's chief executive office and the office
         where the records concerning the Collateral are kept is at its address
         set forth on the signature page hereof. All Collateral shall be kept at
         such address and at such other locations as identified to Lender in
         writing from time-to-time.

                  (j) OPERATION OF BUSINESS. To the best of it's knowledge,
         Borrower possesses all licenses, permits, franchises, patents,
         copyrights, trademarks, and trade names, or rights thereto, to conduct
         business as now conducted and as presently proposed to be conducted,
         and Borrower is not in violation of any valid rights or others with
         respect to any of the foregoing.

         6. AFFIRMATIVE COVENANTS. Until all Indebtedness of Borrower under the
Loan Documents is fully paid and satisfied, and Lender has no further commitment
to lend hereunder, Borrower agrees and covenants that it will, unless Lender
shall otherwise consent in writing:

                  (a) ACCOUNTS AND RECORDS. Maintain its books and records in
         accordance with generally accepted accounting principles.

                  (b) RIGHT OF INSPECTION. Permit Lender to visit its properties
         and installations and to examine, audit and make and take away copies
         or reproductions of Borrower's books and records, at all reasonable
         times and upon prior written notice.

                  (c) RIGHT TO ADDITIONAL INFORMATION. Furnish Lender with such
         information and statements, lists of assets and liabilities, tax
         returns, and other reports with respect to Borrower's financial
         condition and business operations as Lender may reasonably request from
         time to time.

                  (d) COMPLIANCE WITH LAWS. Conduct its business in an orderly
         and efficient manner consistent with good business practices, and
         perform and comply with all applicable statutes, rules, regulations or
         ordinances imposed by any governmental unit upon Borrower, its
         businesses, operations and properties (including without limitation,
         all applicable environmental statutes, rules, regulations and
         ordinances), where the failure to perform or comply could have a
         material adverse effect on the business, operations or properties of
         Borrower.

                  (e) TAXES. Pay and discharge when due all of its indebtedness
         and obligations, including without limitation, all assessments, taxes,
         governmental charges, levies and liens, of every kind and nature,
         imposed upon Borrower or its properties, income, or profits, prior to
         the date on which penalties would attach, and all lawful claims that,
         if unpaid, might become a lien or charge upon any of Borrower's
         properties, income, or profits; provided, however, Borrower will not be
         required to pay and discharge any

LOAN AND SECURITY AGREEMENT  - Page  8

<PAGE>

         such assessment, tax, charge, levy, lien or claim so long as (i) the
         legality of the same shall be contested in good faith by appropriate
         judicial, administrative or other legal proceedings, and (ii) Borrower
         shall have established on its books adequate reserves with respect to
         such contested assessment, tax, charge, levy, lien or claim in
         accordance with generally accepted accounting principles, consistently
         applied.

                  (f) INSURANCE. Maintain insurance, including but not limited
         to, fire insurance, comprehensive property damage, public liability,
         worker's compensation, business interruption and other insurance deemed
         reasonably necessary. Borrower will, at its own expense, maintain
         insurance with respect to all Collateral in such amounts, against such
         risks, in such form and with such insurers, as shall be satisfactory to
         Lender from time to time. Each policy of insurance maintained by
         Borrower shall (i) name Borrower and Lender as insured parties
         thereunder (without any representation or warranty by or obligation
         upon Lender) as their interests may appear, (ii) contain the agreement
         by the insurer that any loss thereunder shall be payable to Lender
         notwithstanding any action, inaction or breach of representation or
         warranty by Borrower, (iii) provide that there shall be no recourse
         against Lender for payment of premiums or other amounts with respect
         thereto, and (iv) provide that at least thirty (30) days prior written
         notice of cancellation or of lapse shall be given to Lender by the
         insurer. Borrower will deliver to Lender original or duplicate policies
         of such insurance and, as often as Lender may reasonably request, a
         report of a reputable insurance broker with respect to such insurance.
         Borrower will also, at the request of Lender, duly execute and deliver
         instruments of assignment of such insurance policies and cause the
         respective insurers to acknowledge notice of such assignment. All
         insurance payments in respect of loss of or damage to any Collateral
         shall be paid to Lender and applied by Lender in accordance with the
         Loan Documents.

                  (g) NOTICE OF INDEBTEDNESS. Promptly inform Lender of the
         creation, incurrence or assumption by Borrower of any actual or
         contingent liabilities not permitted under this Agreement.

                  (h) NOTICE OF LITIGATION. Promptly after the commencement
         thereof, notify Lender of all actions, suits and proceedings before any
         court or any governmental department, commission or board in which
         Borrower is a plaintiff or defendant or any of the properties or assets
         of Borrower are the subject of such actions, suits or proceedings.

                  (i) NOTICE OF MATERIAL ADVERSE CHANGE. Promptly inform Lender
         of (i) any and all material adverse changes in Borrower's financial
         condition, and (ii) all claims made against Borrower that could
         materially affect the financial condition of Borrower.

                  (j) OWNERSHIP AND LIENS. Borrower will maintain good and
         marketable title to all Collateral free and clear of all liens,
         security interests, encumbrances or adverse claims, except for the
         security interest created by this Agreement or Permitted Liens.
         Borrower will cause any financing statement or other security
         instrument with respect to the Collateral to be terminated, except for
         Permitted Liens. Borrower will defend at its expense Lender's right,
         title and security interest in and to the Collateral against the claims
         of any third party.

LOAN AND SECURITY AGREEMENT  - Page  9

<PAGE>

                  (k) FURTHER ASSURANCES. Borrower will from time to time at its
         expense promptly execute and deliver all further instruments and
         documents and take all further action necessary or appropriate or that
         Lender may reasonably request in order (i) to perfect and protect the
         security interest created or purported to be created hereby and the
         priority of such security interest, (ii) to enable Lender to exercise
         and enforce its rights and remedies hereunder in respect of the
         Collateral, and (iii) to otherwise effect the purposes of this
         Agreement, including without limitation: (1) executing and filing such
         financing or continuation statements, or amendments thereto; and (2)
         furnishing to Lender from time to time statements and schedules further
         identifying and describing the Collateral and such other reports in
         connection with the Collateral, all in reasonable detail satisfactory
         to Lender..

                  (l) ACCOUNTS AND GENERAL INTANGIBLES. Borrower will, except as
         otherwise provided herein, collect, at Borrower's own expense, all
         amounts due or to become due under each of the accounts and general
         intangibles. In connection with such collections, Borrower may and, at
         Lender's direction, will take such action not otherwise forbidden
         herein as Borrower or Lender may deem reasonably necessary or advisable
         to enforce collection or performance of each of the accounts and
         general intangibles. Borrower will also duly perform and cause to be
         performed all of its material obligations with respect to the goods or
         services, the sale or lease or rendition of which gave rise or will
         give rise to each account and all of its obligations to be performed
         under or with respect to the general intangibles. Borrower also
         covenants and agrees to take any action and/or execute any documents
         that Lender may request in order to comply with the Federal Assignment
         of Claims Act, as amended.

                  (m) CHATTEL PAPER, DOCUMENTS AND INSTRUMENTS. Borrower will
         take such action as may be requested by Lender in order to cause any
         chattel paper, documents or instruments to be valid and enforceable and
         will cause all chattel paper to have only one original counterpart.
         Upon request by Lender, Borrower will deliver to Lender all originals
         of chattel paper, documents or instruments and will mark all chattel
         paper with a legend indicating that such chattel paper is subject to
         the security interest granted hereunder.

                  (n) MAINTENANCE OF EXISTENCE. Preserve and maintain its
         corporate existence and good standing in the jurisdiction of its
         organization, and qualify and remain qualified as a foreign entity in
         each jurisdiction in which such qualification is required.

                  (o) MAINTENANCE OF PROPERTIES. Maintain, keep, and preserve
         all of its properties (tangible and intangible) necessary or useful in
         the conduct of its business.

                  (p) CONDUCT OF BUSINESS. Continue to engage in an efficient
         and economical manner in a business of the same general type as now
         conducted by it on the date of this Agreement within Borrower's powers
         under organizational documents.

         7. NEGATIVE COVENANTS. Until all Indebtedness of Borrower under the
Loan Documents is fully paid and satisfied, and the Lender has no further
commitment to lend hereunder, Borrower will not, without the prior written
consent of Lender:

         Affiliate of Borrower. As used herein, the term "Affiliate" means any
         individual or entity directly or indirectly controlling, controlled by,
         or under common control with, another individual or entity.

                  (g) DIVIDENDS. Declare or pay any dividends on any equity

         disclosed to Lender, (2) sales of inventory in the ordinary course of
         business, and (3) the sale or other disposal of any item of equipment
         which is worn out or obsolete and which has been replaced by an item of

         in clauses (1) through (3) above shall automatically terminate upon the
         occurrence of an Event of Default.

                  (i) IMPAIRMENT OF SECURITY INTEREST. Take any action that
         would in any manner impair the value or enforceability of Lender's
         security interest in any Collateral.

         amend or modify any Collateral, except an adjustment, settlement,
         compromise, amendment or modification in good faith and in the ordinary
         course of business; provided, however, this exception shall
         automatically terminate upon the occurrence of an Event of Default.
         Borrower shall provide to Lender such information concerning (i) any
         adjustment, settlement, compromise, amendment or modification of any
         Collateral, and (ii) any claim asserted by any account debtor for

         Collateral, (iii) Borrower's chief executive office, or (iv) the state
         of Borrower's organization to a jurisdiction other than as represented
         herein unless Borrower shall have notified Lender in writing of such
         change at least sixty (60) days prior to the effective date of such
         change, and shall have first taken all action required by Lender for
         the purpose of further perfecting or protecting the security interest

         cash (except obligations of the U.S. government).

                  (o) CHANGES IN MANAGEMENT OR OWNERSHIP. Make any changes in
         management that might materially change the character or operating
         philosophy of Borrower.

         8. REPORTING REQUIREMENTS. Until the Indebtedness of Borrower under
this Agreement and the other Loan Documents is fully paid and satisfied, and the
Lender has no further commitment to lend hereunder, Borrower will, unless Lender
shall otherwise consent in writing, furnish to Lender:

         authorizes Lender to file, without the signature of Borrower, one or
         more financing or continuation statements, and amendments thereto,

         Commercial Code jurisdiction any initial financing statements and
         amendments thereto that (i) indicate the Collateral (A) as all assets
         of Borrower or words of similar effect, regardless of whether any
         particular asset comprised in the Collateral falls within the scope of
         Article or Chapter 9 of the Code, or (B) as being of an equal or lesser
         scope or with greater detail, and (ii) contain any other information

<PAGE>

                  (b) POWER OF ATTORNEY. Borrower hereby irrevocably appoints
         Lender as Borrower's attorney-in-fact, such power of attorney being
         coupled with an interest, with full authority in the place and stead of
         Borrower and in the name of Borrower or otherwise, from time to time in
         Lender's reasonable discretion, to take any action and to execute any
         instrument which Lender may deem necessary or appropriate to accomplish
         the purposes of this Agreement, including without limitation: (i) to
         obtain and adjust insurance required by Lender hereunder; (ii) to
         demand, collect, sue for, recover, compound, receive and give
         acquittance and receipts for moneys due and to become due under or in
         respect of the Collateral; (iii) to receive, endorse and collect any
         drafts or other instruments, documents and chattel paper in connection
         with clause (i) or (ii) above; and (iv) to file any claims or take any
         action or institute any proceedings which Lender may deem necessary or
         appropriate for the collection and/or preservation of the Collateral or
         otherwise to enforce the rights of Lender with respect to the
         Collateral.

                  (c) PERFORMANCE BY LENDER. If Borrower fails to perform any
         agreement or obligation provided herein, Lender may itself perform, or
         cause performance of, such agreement or obligation, and the expenses of
         Lender incurred in connection therewith shall be a part of the
         Indebtedness, secured by the Collateral and payable by Borrower on
         demand.

                  (d) BORROWER'S RECEIPT OF PROCEEDS. All amounts and proceeds
         (including instruments and writings) received by Borrower in respect of
         such accounts or general intangibles shall be received in trust for the
         benefit of Lender hereunder and, upon request of Lender, shall be
         segregated from other property of Borrower and shall be forthwith
         delivered to Lender in the same form as so received (with any necessary
         endorsement) and applied to the Indebtedness in accordance with the
         Loan Documents.

                  (e) NOTIFICATION OF ACCOUNT DEBTORS. Lender may at its
         reasonable discretion from time to time notify any or all obligors
         under any accounts or general intangibles (i) of Lender's security
         interest in such accounts or general intangibles and direct such
         obligors to make payment of all amounts due or to become due to
         Borrower thereunder directly to Lender, and (ii) to verify the accounts
         or general intangibles with such obligors. Lender shall have the right,
         at the expense of Borrower, to enforce collection of any such accounts
         or general intangibles and to adjust, settle or compromise the amount
         or payment thereof, in the same manner and to the same extent as
         Borrower.

         within sixty (60) days after the effective date thereof or it consents
         to or acquiesces in such appointment or possession; (iv) files a
         petition for relief under the United States Bankruptcy Code or any
         other present or future federal or state insolvency, Bankruptcy or
         similar laws (all of the foregoing hereinafter collectively called
         "Applicable Bankruptcy Law") or an involuntary petition for relief is

         which such judgment could be executed upon.

                  (i) The Collateral or any portion thereof is taken on
         execution or other process of law in any action against Borrower.

         declares a default thereunder or institutes foreclosure or other
         proceedings for the enforcement of its remedies thereunder.

LOAN AND SECURITY AGREEMENT  - Page  15

<PAGE>

                  (k) This Agreement shall at any time after its execution and
         delivery and for any reason cease (i) to create a valid and perfected
         first priority security interest in and to the property purported to be
         subject to this Agreement; or (ii) to be in full force and effect or
         shall be declared null and void, or the validity of enforceability
         hereof shall be contested by Borrower, or Borrower shall deny it has
         any further liability or obligation under this Agreement or the other
         Loan Documents.

Nothing contained in this Agreement shall be construed to limit the events of
default enumerated in any of the other Loan Documents and all such events of
default shall be cumulative.

         11.      REMEDIES AND RELATED RIGHTS. If an Event of Default shall have
occurred, and without limiting any other rights and remedies provided herein,
under any of the Loan Documents or otherwise available to Lender, Lender may
exercise one or more of the rights and remedies provided in this Section.

                  (a) REMEDIES. Upon the occurrence of any one or more of the
         foregoing Events of Default, (i) the entire unpaid balance of principal
         of the Notes, together with all accrued but unpaid interest thereon,
         and all other indebtedness owing to Lender by Borrower at such time
         shall, at the option of Lender, become immediately due and payable
         without further notice, demand, presentation, notice of dishonor,
         notice of intent to accelerate, notice of acceleration, protest or
         notice of protest of any kind, all of which are expressly waived by
         Borrower, and (ii) Lender may, at its option, cease further advances
         under the Notes and this Agreement; provided, however, concurrently and
         automatically with the occurrence of an Event of Default under
         Subsection 13(f): (i) further advances under the Notes and this
         Agreement, and (ii) the Notes and all other Indebtedness owing to
         Lender by Borrower at such time shall, without any action by Lender,
         become due and payable, without further notice, demand, presentation,
         notice of dishonor, notice of acceleration, notice of intent to
         accelerate, protest or notice of protest of any kind, all of which are
         expressly waived by Borrower. All rights and remedies of Lender set
         forth in this Agreement and in any of the other Loan Documents may also
         be exercised by Lender, at its option to be exercised in its sole
         discretion, upon the occurrence of an Event of Default, and not in
         substitution or diminution of any rights now or hereafter held by
         Lender under the terms of any other agreement.

                  (b) OTHER REMEDIES. Lender may from time to time at its
         discretion, without limitation and without notice except as expressly
         provided in any of the Loan Documents:

                           (i) exercise in respect of the Collateral all the
                  rights and remedies of a Lender under the Code (whether or not
                  the Code applies to the affected Collateral);

                           (ii) require Borrower to, and Borrower hereby agrees
                  that it will at its expense and upon request of Lender,
                  assemble the Collateral as directed by Lender and make it
                  available to Lender at a place to be designated by Lender
                  which is reasonably convenient to both parties;

LOAN AND SECURITY AGREEMENT  - Page  16

<PAGE>

                           (iii) reduce its claim to judgment or foreclose or
                  otherwise enforce, in whole or in part, the security interest
                  granted hereunder by any available judicial procedure;

                           (iv) sell or otherwise dispose of, at its office, on
                  the premises of Borrower or elsewhere, the Collateral, as a
                  unit or in parcels, by public or private proceedings, and by
                  way of one or more contracts (it being agreed that the sale or
                  other disposition of any part of the Collateral shall not
                  exhaust Lender's power of sale, but sales or other
                  dispositions may be made from time to time until all of the
                  Collateral has been sold or disposed of or until the
                  Indebtedness has been paid and performed in full), and at any
                  such sale or other disposition it shall not be necessary to
                  exhibit any of the Collateral;

                           (v) buy the Collateral, or any portion thereof, at
                  any public sale;

                           (vi) buy the Collateral, or any portion thereof, at
                  any private sale if the Collateral is of a type customarily
                  sold in a recognized market or is of a type which is the
                  subject of widely distributed standard price quotations;

                           (vii) apply for the appointment of a receiver for the
                  Collateral, and Borrower hereby consents to any such
                  appointment; and

                           (viii) at its option, retain the Collateral in
                  satisfaction of the Indebtedness whenever the circumstances
                  are such that Lender is entitled to do so under the Code or
                  otherwise.

                  Borrower agrees that in the event Borrower is entitled to
                  receive any notice under the Uniform Commercial Code, as it
                  exists in the state governing any such notice, of the sale or
                  other disposition of any Collateral, reasonable notice shall
                  be deemed given when such notice is deposited in a depository
                  receptacle under the care and custody of the United States
                  Postal Service, postage prepaid, at Borrower's address set
                  forth on the signature page hereof, five (5) days prior to the
                  date of any public sale, or after which a private sale, of any
                  of such Collateral is to be held. Lender shall not be
                  obligated to make any sale of Collateral regardless of notice
                  of sale having been given. Lender may adjourn any public or
                  private sale from time to time by announcement at the time and
                  place fixed therefor, and such sale may, without further
                  notice, be made at the time and place to which it was so
                  adjourned.

                  (c) APPLICATION OF PROCEEDS. If any Event of Default shall
         have occurred, Lender may at its discretion apply or use any cash held
         by Lender as Collateral, and any cash proceeds received by Lender in
         respect of any sale or other disposition of, collection from, or other
         realization upon, all or any part of the Collateral as follows in such
         order and manner as Lender may elect:

                           (i) to the repayment or reimbursement of the
                  reasonable costs and expenses (including, without limitation,
                  reasonable attorneys' fees and expenses) incurred by Lender in
                  connection with (1) the administration of the Loan Documents,
                  (2) the custody, preservation, use or operation of, or the
                  sale of, collection from, or other

LOAN AND SECURITY AGREEMENT  - Page  17

<PAGE>

                  realization upon, the Collateral, and (3) the exercise or
                  enforcement of any of the rights and remedies of Lender
                  hereunder;

                           (ii) to the payment or other satisfaction of any
                  liens and other encumbrances upon the Collateral;

                           (iii) to the satisfaction of the Indebtedness;

                           (iv) by holding such cash and proceeds as Collateral;

                           (v) to the payment of any other amounts required by
                  applicable law (including without limitation, Section
                  9.504(a)(3) of the Code or any other applicable statutory
                  provision); and

                           (vi) by delivery to Borrower or any other party
                  lawfully entitled to receive such cash or proceeds whether by
                  direction of a court of competent jurisdiction or otherwise.

                  (d) DEFICIENCY. In the event that the proceeds of any sale of,
         collection from, or other realization upon, all or any part of the
         Collateral by Lender are insufficient to pay all amounts to which
         Lender is legally entitled, Borrower and any party who guaranteed or is
         otherwise obligated to pay all or any portion of the Indebtedness shall
         be liable for the deficiency, together with interest thereon as
         provided in the Loan Documents.

                  (e) NON-JUDICIAL REMEDIES. In granting to Lender the power to
         enforce its rights hereunder without prior judicial process or judicial
         hearing, Borrower expressly waives, renounces and knowingly
         relinquishes any legal right which might otherwise require Lender to
         enforce its rights by judicial process. Borrower recognizes and
         concedes that non-judicial remedies are consistent with the usage of
         trade, are responsive to commercial necessity and are the result of a
         bargain at arm's length. Nothing herein is intended to prevent Lender
         or Borrower from resorting to judicial process at either party's
         option.

                  (f) OTHER RECOURSE. Borrower waives any right to require
         Lender to proceed against any third party, exhaust any Collateral or
         other security for the Indebtedness, or to have any third party joined
         with Borrower in any suit arising out of the Indebtedness or any of the
         Loan Documents, or pursue any other remedy available to Lender.
         Borrower further waives any and all notice of acceptance of this
         Agreement and of the creation, modification, rearrangement, renewal or
         extension of the Indebtedness. Borrower further waives any defense
         arising by reason of any disability or other defense of any third party
         or by reason of the cessation from any cause whatsoever of the
         liability of any third party. Until all of the Indebtedness shall have
         been paid in full, Borrower shall have no right of subrogation and
         Borrower waives the right to enforce any remedy which Lender has or may
         hereafter have against any third party, and waives any benefit of and
         any right to participate in any other security whatsoever now or
         hereafter held by Lender. Borrower authorizes Lender, and without
         notice or demand and without any reservation of rights against Borrower
         and without affecting Borrower's liability hereunder or on the

LOAN AND SECURITY AGREEMENT  - Page  18

<PAGE>

         Indebtedness to (i) take or hold any other property of any type from
         any third party as security for the Indebtedness, and exchange,
         enforce, waive and release any or all of such other property, (ii)
         apply such other property and direct the order or manner of sale
         thereof as Lender may in its discretion determine, (iii) renew, extend,
         accelerate, modify, compromise, settle or release any of the
         Indebtedness or other security for the Indebtedness, (iv) waive,
         enforce or modify any of the provisions of any of the Loan Documents
         executed by any third party, and (v) release or substitute any third
         party.

         12. INDEMNITY. Borrower hereby indemnifies and agrees to hold harmless
Lender, and its officers, directors, employees, agents and representatives (each
an "Indemnified Person") from and against any and all liabilities, obligations,
claims, losses, damages, penalties, actions, judgments, suits, costs, expenses
or disbursements of any kind or nature (collectively, the "Claims") which may be
imposed on, incurred by, or asserted against, any Indemnified Person arising in
connection with the Loan Documents, the Indebtedness or the Collateral
(including without limitation, the enforcement of the Loan Documents and the
defense of any Indemnified Person's actions and/or inactions in connection with
the Loan Documents). WITHOUT LIMITATION, THE FOREGOING INDEMNITIES SHALL APPLY
TO EACH INDEMNIFIED PERSON WITH RESPECT TO ANY CLAIMS WHICH IN WHOLE OR IN PART
ARE CAUSED BY OR ARISE OUT OF THE NEGLIGENCE OF SUCH AND/OR ANY OTHER
INDEMNIFIED PERSON, except to the limited extent the Claims against an
Indemnified Person are proximately caused by such Indemnified Person's gross
negligence or willful misconduct. If Borrower or any third party ever alleges
such gross negligence or willful misconduct by any Indemnified Person, the
indemnification provided for in this Section shall nonetheless be paid upon
demand, subject to later adjustment or reimbursement, until such time as a court
of competent jurisdiction enters a final judgment as to the extent and effect of
the alleged gross negligence or willful misconduct. The indemnification provided
for in this Section shall survive the termination of this Agreement and shall
extend and continue to benefit each individual or entity who is or has at any
time been an Indemnified Person hereunder.

         13. WAIVER AND AGREEMENT. Neither the failure nor any delay on the part
of Lender to exercise any right, power or privilege herein or under any of the
other Loan Documents shall operate as a waiver thereof, nor shall any single or
partial exercise of such right, power or privilege preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. No
waiver of any provision in this Agreement or in any of the other Loan Documents
and no departure by Borrower therefrom shall be effective unless the same shall
be in writing and signed by Lender, and then shall be effective only in the
specific instance and for the purpose for which given and to the extent
specified in such writing. No modification or amendment to this Agreement or to
any of the other Loan Documents shall be valid or effective unless the same is
signed by the party against whom it is sought to be enforced.

         14. BENEFITS. This Agreement shall be binding upon and inure to the
benefit of Lender and Borrower, and their respective successors and assigns,
provided, however, that Borrower may not, without the prior written consent of
Lender, assign any rights, powers, duties or obligations under this Agreement or
any of the other Loan Documents.

on the signature page hereof is located.

         17. INVALID PROVISIONS. If any provision of this Agreement or any of
the other Loan Documents are held to be illegal, invalid or unenforceable under
present or future laws, such provision shall be fully severable and the
remaining provisions of this Agreement or any of the other Loan Documents shall
remain in full force and effect and shall not be affected by the illegal,
invalid or unenforceable provision or by its severance.

         18. EXPENSES. Borrower shall pay all costs and expenses (including,
without limitation, reasonable attorneys' fees) in connection with (a) the
drafting and execution of the Loan Documents and the transactions contemplated
therein (b) any action required in the course of administration of the
indebtedness and obligations evidenced by the Loan Documents, and (c) any action
in the enforcement of Lender's rights upon the occurrence of an Event of
Default.

         19. PARTICIPATION OF THE LOANS. Borrower agrees that Lender may, at its
option, sell interests in the Loans and its rights under this Agreement to a
financial institution or institutions and, in connection with each such sale,
Lender may disclose any financial and other information available to Lender
concerning Borrower to each perspective purchaser subject to obtaining a
confidentiality agreement with each prospective purchaser prior to disclosing
Borrower's confidential information.

         20. CONFLICTS. In the event any term or provision hereof is
inconsistent with or conflicts with any provision of the other Loan Documents,
the terms and provisions contained in this Agreement shall be controlling.

         21. COUNTERPARTS. This Agreement may be separately executed in any
number of counterparts, each of which shall be an original, but all of which,
taken together, shall be deemed to constitute one and the same instrument.

                            (REVOLVING CREDIT NOTE)

$2,000,000.00                                                   October 15, 2003

         FOR VALUE RECEIVED, on or before the Revolving Maturity Date,
VIEWCAST.COM, INC. a Delaware corporation, OSPREY TECHNOLOGIES, INC., a Delaware
corporation, and VIDEOWARE, INC., a Delaware corporation (jointly and severally,
"Borrower"), promises to pay to the order of ARDINGER FAMILY PARTNERSHIP, LTD.
("Lender") at its offices at 1990 Lakepointe Drive, Lewisville, TX 75057 the
principal amount of TWO MILLION AND NO/100 DOLLARS ($2,000,000.00) or such which
is outstanding from time to time (the "Total Principal Amount") under this
promissory note ("Note"), together with interest on such portion of the Total
Principal Amount which has been advanced to Borrower from the date advanced
until paid at a rate per annum equal to the lesser of (a) the Maximum Rate (as
defined below), (b) a rate (the "Contract Rate") equal to the sum of (i) the
Prime Rate (as defined below), plus (ii) three percent (3%), or (c) nine and
one-half percent (9.50%), each change in the rate to be charged on this Note to
become effective without notice to Borrower on the effective date of each such
change in the Maximum Rate or the Prime Rate, as the case may be; provided,
however, that if at any time the Contract Rate shall exceed the Maximum Rate,
thereby causing the interest on this Note to be limited to the Maximum Rate,
then any subsequent reduction in the Prime Rate shall not reduce the rate of
interest on this Note below the Maximum Rate until the total amount of interest
accrued on this Note equals the amount of interest which would have accrued on
this Note if the Contract Rate had at all times been in effect.

         "Prime Rate" means the rate of interest per annum which is equal to the
variable rate of interest per annum equal to the prime rate as published from
time to time in the "Money Rates" table of The Wall Street Journal (Southwest
Edition) as of the date of this Note and as of the first Business Day of each
calendar year thereafter. If the prime rate is no longer published in the "Money
Rates" table of The Wall Street Journal (Southwest Edition), then Lender will
choose a substitute index that is based upon comparable information. "Maximum
Rate," means at the particular time in question the maximum rate of interest
that, under applicable law, may then be charged on this Note.

         The principal balance of and all accrued but unpaid interest on this
Note shall be due and payable as follows:

         (a)  Interest shall be due and payable on demand as it accrues; and

         (b) Thereafter, one (1) final installment of all outstanding principal
         and all accrued and unpaid interest hereunder shall be due and payable
         on the Revolving Maturity Date.

         This Note evidences Indebtedness from time to time owing by Borrower to
Lender pursuant to that certain Amended and Restated Loan and Security Agreement
dated as of October 15, 2003 by and between Borrower and Lender (as amended,
restated and modified from

Amended and Restated Promissory Note - Page 1

time to time, the "Loan Agreement"). The holder of this Note is entitled to the
benefits and security provided in the Loan Documents. This Note is the note
referred to in the Loan Agreement as the "Revolving Credit Note." Capitalized
terms not otherwise defined herein, shall have the same meanings as in the Loan
Agreement.

         Under the Loan Agreement, and pursuant to the terms thereof, Borrower
may request advances and make payments hereunder from time to time, provided
that it is understood and agreed that the aggregate principal amount outstanding
from time to time hereunder shall not at any time exceed the Total Principal
Amount. The unpaid balance of this Note shall increase and decrease with each
new advance or payment hereunder, as the case may be. This Note shall not be
deemed terminated or canceled prior to the Revolving Maturity Date set forth for
this Note, although the entire principal balance hereof may from time to time be
paid in full. Pursuant to the terms of the Loan Agreement, Borrower may borrow,
repay and reborrow hereunder. Unless otherwise agreed to in writing, or
otherwise required by applicable law, payments will be applied first to unpaid
accrued interest, then to principal, and any remaining amount to any unpaid
collection costs, delinquency charges and other charges; provided, however, upon
occurrence of another Event of Default, Lender reserves the right to apply
payments among principal, interest, delinquency charges, collection costs and
other charges, at its discretion. All payments of principal or interest on this
Note shall be made in lawful money of the United States of America in
immediately available funds, at the address of Lender indicated above, or such
other place as the holder of this Note shall designate in writing to Borrower.
If any payment of principal or interest on this Note shall become due on a day,
which is not a Business Day (as hereinafter defined), such payment shall be made
on the next succeeding Business Day and any such extension of time shall be
included in computing interest in connection with such payment. As used herein,
the term "Business Day" shall mean any day other than a Saturday, Sunday or any
other day on which national banking associations are authorized to be closed.
The books and records of Lender shall be prima facie evidence of all outstanding
principal and accrued and unpaid interest on this Note.

         Borrower agrees that upon the occurrence of any one or more Events of
Default the holder of this Note may, at its option, without further notice or
demand, (i) declare the outstanding principal balance of and accrued but unpaid
interest on this Note at once due and payable, (ii) foreclose all liens securing
payment hereof, (iii) pursue any and all other rights, remedies and resources
available to the holder hereof, including but not limited to any such rights,
remedies or resources under the Loan Documents, at law or in equity, or (iv)
pursue any combination of the foregoing.

         The failure to exercise the option to accelerate the maturity of this
Note or any other right, remedy or recourse available to the holder hereof upon
the occurrence of an Event of Default hereunder shall not constitute a waiver of
the right of the holder of this Note to exercise the same at that time or at any
subsequent time with respect to such Event of Default or any other Event of
Default. The rights, remedies and resources of the holder hereof, as provided in
this Note and in any of the other Loan Documents, shall be cumulative and
concurrent and may be pursued separately, successively or together as often as
occasion therefore shall arise, at the sole discretion of the holder hereof. The
acceptance by the holder hereof of any payment under this Note which is less
than the payment in full of all amounts due and payable at the time of such
payment shall not (i) constitute a waiver of or impair, reduce, release or
extinguish any right, remedy or recourse of the holder hereof, or nullify any
prior exercise of any such right, remedy

Amended and Restated Promissory Note - Page 2

<PAGE>

or recourse, or (ii) impair, reduce, release or extinguish the obligations of
any party liable under any of the Loan Documents as originally provided herein
or therein.

         This Note and all of the other Loan Documents are intended to be
performed in accordance with, and only to the extent permitted by, all
applicable usury laws. If any provision hereof or of any of the other Loan
Documents or the application thereof to any person or circumstance shall, for
any reason and to any extent, be invalid or unenforceable, neither the
application of such provision to any other person or circumstance nor the
remainder of the instrument in which such provision is contained shall be
affected thereby and shall be enforced to the greatest extent permitted by law.
It is expressly stipulated and agreed to be the intent of the holder hereof to
at all times comply with the usury and other applicable laws now or hereafter
governing the interest payable on the indebtedness evidenced by this Note. If
the applicable law is ever revised, repealed or judicially interpreted so as to
render usurious any amount called for under this Note or under any of the other
Loan Documents, or contracted for, charged, taken, reserved or received with
respect to the indebtedness evidenced by this Note, or if Lender's exercise of
the option to accelerate the Revolving Maturity of this Note, or if any
prepayment by Borrower results in Borrower having paid any interest in excess of
that permitted by law, then it is the express intent of Borrower and Lender that
all excess amounts theretofore collected by Lender be credited on the principal
balance of this Note (or, if this Note and all other indebtedness arising under
or pursuant to the other Loan Documents have been paid in full, refunded to
Borrower), and the provisions of this Note and the other Loan Documents
immediately be deemed reformed and the amounts thereafter collectable hereunder
and thereunder reduced, without the necessity of the execution of any new
document, so as to comply with the then applicable law, but so as to permit the
recovery of the fullest amount otherwise called for hereunder or thereunder. All
sums paid, or agreed to be paid, by Borrower for the use, forbearance,
detention, taking, charging, receiving or reserving of the indebtedness of
Borrower to Lender under this Note or arising under or pursuant to the other
Loan Documents shall, to the maximum extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full so that the rate or amount of interest on
account of such indebtedness does not exceed the usury ceiling from time to time
in effect and applicable to such indebtedness for so long as such indebtedness
is outstanding. To the extent federal law permits Lender to contract for, charge
or receive a greater amount of interest, Lender will rely on federal law instead
of the Texas Finance Code, as supplemented by Texas Credit Title for the purpose
of determining the Maximum Rate. Additionally, to the maximum extent permitted
by applicable law now or hereafter in effect, Lender may, at its option and from
time to time, implement any other method of computing the Maximum Rate under the
Texas Finance Code, as supplemented by Texas Credit Title, or under other
applicable law by giving notice, if required, to Borrower as provided by
applicable law now or hereafter in effect. Notwithstanding anything to the
contrary contained herein or in any of the other Loan Documents, it is not the
intention of Lender to accelerate the Revolving Maturity of any interest that
has not accrued at the time of such acceleration or to collect unearned interest
at the time of such acceleration.

         If this Note is placed in the hands of an attorney for collection, or
is collected in whole or in part by suit or through probate, bankruptcy or other
legal proceedings of any kind, Borrower agrees to pay, in addition to all other
sums payable hereunder, all costs and expenses of collection, including but not
limited to reasonable attorneys' fees.

further notice hereby agree to renewals, extensions, exchanges or releases of
collateral, taking of additional collateral, indulgences or partial payments,
either before or after Revolving Maturity.

EXTINGUISHMENT OF ALL AMOUNTS LEFT OWING AND UNPAID UNDER THAT CERTAIN

$6,909,582.25                                                   October 15, 2003

         FOR VALUE RECEIVED, on or before the Term Maturity Date, VIEWCAST.COM,
INC. a Delaware corporation, OSPREY TECHNOLOGIES, INC., a Delaware corporation,
and VIDEOWARE, INC., a Delaware corporation (jointly and severally, "Borrower"),
promises to pay to the order of ARDINGER FAMILY PARTNERSHIP, LTD. a Texas
partnership ("Lender") at its offices at 1990 Lakepointe Drive, Lewisville, TX
75057 the principal amount of SIX MILLION NINE HUNDRED AND NINE THOUSAND FIVE
HUNDRED AND EIGHTY-TWO AND 25/100 DOLLARS ($6,909,582.25) or such which is
outstanding from time to time (the "Total Principal Amount") under this
promissory note ("Note"), together with interest on the Total Principal Amount
from the date hereof until paid at a fluctuating rate per annum which shall from
be equal to the lesser of (a) the Maximum Rate (as defined below), (b) a rate
(the "Contract Rate") equal to the sum of (i) the Prime Rate (as defined below),
plus (ii) three percent (3%), or (c) nine and one-half percent (9.50%), each
change in the rate to be charged on this Note to become effective without notice
to Borrower on the effective date of each such change in the Maximum Rate or the
Prime Rate, as the case may be; provided, however, that if at any time the
Contract Rate shall exceed the Maximum Rate, thereby causing the interest on
this Note to be limited to the Maximum Rate, then any subsequent reduction in
the Prime Rate shall not reduce the rate of interest on this Note below the
Maximum Rate until the total amount of interest accrued on this Note equals the
amount of interest which would have accrued on this Note if the Contract Rate
had at all times been in effect.

         "Prime Rate" means the rate of interest per annum which is equal to the
variable rate of interest per annum equal to the prime rate as published from
time to time in the "Money Rates" table of The Wall Street Journal (Southwest
Edition) as of the date of this Note and as of the first Business Day of each
calendar year thereafter. If the prime rate is no longer published in the "Money
Rates" table of The Wall Street Journal (Southwest Edition), then Lender will
choose a substitute index that is based upon comparable information. "Maximum
Rate," means at the particular time in question the maximum rate of interest
that, under applicable law, may then be charged on this Note.

         The principal balance of and all accrued but unpaid interest on this
Note shall be due and payable as follows:

         (a) Thirty (33) consecutive monthly principal payments in the amount
         equal to a thirty (30) year amortization (monthly) of the Total
         Principal Amount outstanding as of the date of this Note shall be due
         and payable commencing on April 30, 2004 and continuing on the last day
         of each calendar month thereafter; and

         (b) One (1) final installment of all outstanding principal and all
         accrued and unpaid interest hereunder shall be due and payable on the
         Term Maturity Date.

At maturity (whether by acceleration or otherwise), Borrower must repay the
entire principal balance of this Note and unpaid interest then due. Lender is
under no obligation to refinance the

Promissory Note - Page 1

<PAGE>

Term Loan at that time. Borrower will, therefore, be required to make payment
out of other assets Borrower may own; or Borrower will have to find a lender
willing to lend Borrower the money at prevailing market rates, which may be
considerably higher than the interest rate on the Loan.

         This Note evidences Indebtedness owing by Borrower to Lender pursuant
to that certain Amended and Restated Loan and Security Agreement dated as of
October 15, 2003 by and between Borrower and Lender (as amended, restated and
modified from time to time, the "Loan Agreement"). The holder of this Note is
entitled to the benefits and security provided in the Loan Documents. This Note
is the note referred to in the Loan Agreement as the "Term Note." Capitalized
terms not otherwise defined herein, shall have the same meanings as in the Loan
Agreement. This Note may be prepaid in whole or in part at any time. This Note
is subject to the mandatory prepayment provisions set forth in the Loan
Agreement.

         Unless otherwise agreed to in writing, or otherwise required by
applicable law, payments will be applied first to unpaid accrued interest, then
to principal, and any remaining amount to any unpaid collection costs,
delinquency charges and other charges; provided, however, upon occurrence of
another Event of Default, Lender reserves the right to apply payments among
principal, interest, delinquency charges, collection costs and other charges, at
its discretion. All payments of principal or interest on this Note shall be made
in lawful money of the United States of America in immediately available funds,
at the address of Lender indicated above, or such other place as the holder of
this Note shall designate in writing to Borrower. If any payment of principal or
interest on this Note shall become due on a day, which is not a Business Day (as
hereinafter defined), such payment shall be made on the next succeeding Business
Day and any such extension of time shall be included in computing interest in
connection with such payment. As used herein, the term "Business Day" shall mean
any day other than a Saturday, Sunday or any other day on which national banking
associations are authorized to be closed. The books and records of Lender shall
be prima facie evidence of all outstanding principal and accrued and unpaid
interest on this Note.

         Borrower agrees that upon the occurrence of any one or more Events of
Default the holder of this Note may, at its option, without further notice or
demand, (i) declare the outstanding principal balance of and accrued but unpaid
interest on this Note at once due and payable, (ii) foreclose all liens securing
payment hereof, (iii) pursue any and all other rights, remedies and resources
available to the holder hereof, including but not limited to any such rights,
remedies or resources under the Loan Documents, at law or in equity, or (iv)
pursue any combination of the foregoing.

         The failure to exercise the option to accelerate the maturity of this
Note or any other right, remedy or recourse available to the holder hereof upon
the occurrence of an Event of Default hereunder shall not constitute a waiver of
the right of the holder of this Note to exercise the same at that time or at any
subsequent time with respect to such Event of Default or any other Event of
Default. The rights, remedies and resources of the holder hereof, as provided in
this Note and in any of the other Loan Documents, shall be cumulative and
concurrent and may be pursued separately, successively or together as often as
occasion therefore shall arise, at the sole discretion of the holder hereof. The
acceptance by the holder hereof of any payment under this Note which is less
than the payment in full of all amounts due and payable at the time of such
payment shall not (i) constitute a waiver of or impair, reduce, release or
extinguish any right,

remedy or recourse of the holder hereof, or nullify any prior exercise of any
such right, remedy or recourse, or (ii) impair, reduce, release or extinguish
the obligations of any party liable under any of the Loan Documents as
originally provided herein or therein.

         This Note and all of the other Loan Documents are intended to be
performed in accordance with, and only to the extent permitted by, all
applicable usury laws. If any provision hereof or of any of the other Loan
Documents or the application thereof to any person or circumstance shall, for
any reason and to any extent, be invalid or unenforceable, neither the
application of such provision to any other person or circumstance nor the
remainder of the instrument in which such provision is contained shall be
affected thereby and shall be enforced to the greatest extent permitted by law.
It is expressly stipulated and agreed to be the intent of the holder hereof to
at all times comply with the usury and other applicable laws now or hereafter
governing the interest payable on the indebtedness evidenced by this Note. If
the applicable law is ever revised, repealed or judicially interpreted so as to
render usurious any amount called for under this Note or under any of the other
Loan Documents, or contracted for, charged, taken, reserved or received with
respect to the indebtedness evidenced by this Note, or if Lender's exercise of
the option to accelerate the Term Maturity of this Note, or if any prepayment by
Borrower results in Borrower having paid any interest in excess of that
permitted by law, then it is the express intent of Borrower and Lender that all
excess amounts theretofore collected by Lender be credited on the principal
balance of this Note (or, if this Note and all other indebtedness arising under
or pursuant to the other Loan Documents have been paid in full, refunded to
Borrower), and the provisions of this Note and the other Loan Documents
immediately be deemed reformed and the amounts thereafter collectable hereunder
and thereunder reduced, without the necessity of the execution of any new
document, so as to comply with the then applicable law, but so as to permit the
recovery of the fullest amount otherwise called for hereunder or thereunder. All
sums paid, or agreed to be paid, by Borrower for the use, forbearance,
detention, taking, charging, receiving or reserving of the indebtedness of
Borrower to Lender under this Note or arising under or pursuant to the other
Loan Documents shall, to the maximum extent permitted by applicable law, be
amortized, prorated, allocated and spread throughout the full term of such
indebtedness until payment in full so that the rate or amount of interest on
account of such indebtedness does not exceed the usury ceiling from time to time
in effect and applicable to such indebtedness for so long as such indebtedness
is outstanding. To the extent federal law permits Lender to contract for, charge
or receive a greater amount of interest, Lender will rely on federal law instead
of the Texas Finance Code, as supplemented by Texas Credit Title for the purpose
of determining the Maximum Rate. Additionally, to the maximum extent permitted
by applicable law now or hereafter in effect, Lender may, at its option and from
time to time, implement any other method of computing the Maximum Rate under the
Texas Finance Code, as supplemented by Texas Credit Title, or under other
applicable law by giving notice, if required, to Borrower as provided by
applicable law now or hereafter in effect. Notwithstanding anything to the
contrary contained herein or in any of the other Loan Documents, it is not the
intention of Lender to accelerate the Term Maturity of any interest that has not
accrued at the time of such acceleration or to collect unearned interest at the
time of such acceleration.

         If this Note is placed in the hands of an attorney for collection, or
is collected in whole or in part by suit or through probate, bankruptcy or other
legal proceedings of any kind, Borrower agrees to pay, in addition to all other
sums payable hereunder, all costs and expenses of collection, including but not
limited to reasonable attorneys' fees.

                  AMENDED AND RESTATED PLEDGE AGREEMENT

         THIS PLEDGE AGREEMENT (as amended, modified or restated from
time-to-time, this "Agreement") is dated as of October 15, 2003, and entered
into by and between VIEWCAST.COM, INC., a Delaware corporation ("Borrower"), and
ARDINGER FAMILY PARTNERSHIP, LTD., ("Lender").

                                     PRELIMINARY STATEMENTS

         A. Borrower and Lender have entered into an Amended and Restated Loan
and Security Agreement of even date herewith (as amended, restated, supplemented
or otherwise modified from time-to-time, being the "Loan Agreement"). Terms
defined in the Loan Agreement and not otherwise defined herein being used herein
as therein defined.

         B. Borrower owns one hundred percent (100%) of the issued and
outstanding equity interests of the entities listed on Schedule I (each, a
"Company").

         C. It is a condition precedent to the making of Loans by Lender under
the Loan Agreement that the Indebtedness thereunder and pursuant to this
Agreement, shall be secured by the equity interests of the Companies.

         NOW, THEREFORE, in consideration of the premises and in order to induce
the Lenders to make Loans under the Loan Agreement and for other good and
valuable consideration, the receipt and adequacy of which are hereby
acknowledged, Borrower hereby agrees with Lender as follows:

         SECTION 1. Pledge of Security. Borrower hereby assigns and pledges to
Lender, and hereby grants to Lender, all of Borrower's right, title and interest
in and to the following (the "Pledged Collateral"):

                  (a) the equity interests described on Schedule I annexed
         hereto (the "Pledged Interests") and any certificates representing the
         Pledged Interests and any interest of Borrower in the entries on the
         books of each Company and of any financial intermediary pertaining to
         the Pledged Interests, and all dividends, distributions, cash,
         warrants, rights, instruments and other property or proceeds from time
         to time received, receivable or otherwise distributed in respect of or
         in exchange for any or all of the Pledged Interests;

                  (b) all additional securities of, and all securities
         convertible into and warrants, options and other rights to purchase or
         otherwise acquire, stock of any issuer of any of the Pledged Interests
         that from time to time are acquired by Borrower in any manner (which
         shares, securities, warrants, options and other rights shall be deemed
         to be part of the Pledged Interests), the certificates or other
         instruments representing such additional shares, securities, warrants,
         options or other rights and any interest of Borrower in the entries on
         the books of each Company and any financial intermediary pertaining to
         such additional shares, securities, warrants, options and other rights,
         and all dividends, distributions, cash, warrants, rights, instruments
         and other property or proceeds from time to time received, receivable
         or

PLEDGE AGREEMENT - Page 1

<PAGE>

         otherwise distributed in respect of or in exchange for any or all of
         such additional shares, securities, warrants, options or other rights;
         and

                  (c) to the extent not covered by clauses (a) through (b)
         above, all general intangibles (including causes of action) relating
         to, and all proceeds of, any or all of the foregoing Pledged
         Collateral.

For purposes of this Agreement: (i) the term "proceeds" means and includes
whatever is receivable or received when Pledged Collateral or proceeds thereof
are sold, exchanged, collected or otherwise disposed of, whether such
disposition is voluntary or involuntary, and includes, without limitation,
proceeds of any indemnity or guaranty payable to Borrower or Lender from time to
time with respect to any of the Pledged Collateral, and (ii) unless otherwise
defined herein or in the Loan Agreement, terms used in Article 9 of the Uniform
Commercial Code in the State of Texas are used herein as therein defined.

         SECTION 2. Security for Secured Indebtedness. This Agreement secures,
and the Pledged Collateral is collateral security for, the prompt payment or
performance in full when due, whether at stated maturity, by required
prepayment, declaration, acceleration, demand or otherwise (including the
payment of amounts that would become due but for the operation of the automatic
stay under Section 362(a) of the Bankruptcy Code), of:

         (a)      the Indebtedness (as defined in the Loan Agreement); and

         (b)      all Indebtedness of every nature of Borrower now or hereafter
                  existing under this Agreement and/or any other Loan Document
                  to which Borrower is a party;

the Indebtedness, together with all such Indebtedness of Borrower, being herein
called the "Secured Indebtedness".

         SECTION 3. Delivery of Pledged Collateral. All certificates or
instruments representing or evidencing the Pledged Collateral shall be delivered
to and held by or on behalf of Lender pursuant hereto and shall be in suitable
form for transfer by delivery or, as applicable, shall be accompanied by
Borrower's endorsement, where necessary, or duly executed instruments of
transfer or assignment in blank substantially in the form of Schedule III
annexed hereto, all in form and substance reasonably satisfactory to Lender.
Lender shall have the right, at any time, in its discretion and without notice
to Borrower, to transfer to or to register in the name of Lender or any of its
nominees any or all of the Pledged Collateral, subject only to the revocable
rights specified in Section 7(a) of this Agreement. In addition, Lender shall
have the right at any time to exchange certificates or instruments representing
or evidencing Pledged Collateral for certificates or instruments of smaller or
larger denominations.

         SECTION 4. Representations and Warranties. Borrower represents and
warrants as follows:

                  (a) Capitalization. The authorized capitalization of each
         Company is set forth on Schedule I attached hereto. Borrower is the
         record owner of the Pledged Collateral.

PLEDGE AGREEMENT - Page 2

<PAGE>

                  (b) Due Authorization, etc. of Pledged Interests. All of the
         Pledged Interests have been duly authorized and validly issued and are
         fully paid and non-assessable. There are no outstanding options,
         subscriptions, warrants or agreements by which either Company is bound
         calling for the issuance of shares of any class of its capital stock or
         for the issuance of any securities, convertible or exchangeable,
         actually or contingently, into shares of its capital stock.

                  (c) Ownership of Pledged Collateral. Borrower is the legal,
         record and beneficial owner of the Pledged Collateral free and clear of
         any Lien except for the security interest created by this Agreement.

                  (d) Perfection; Name; Locations. The pledge of the Pledged
         Collateral pursuant to this Agreement creates a valid and enforceable
         security interest in the Pledged Collateral, securing the payment of
         the Secured Indebtedness, except to the extent the enforceability
         thereof may be limited by applicable bankruptcy, insolvency,
         reorganization, moratorium or other similar laws generally affecting
         creditors' rights and by equitable principles regardless of whether
         enforceability is sought in equity or at law. Upon the delivery to
         Lender of certificates representing the Pledged Interests and the
         filing of a UCC-1 Financing Statement naming Borrower as debtor and
         Lender as Lender covering the Pledged Collateral in the office of the
         Department of State of Texas, the security interest created hereby
         shall constitute a perfected, first priority security interest upon the
         Pledged Collateral which shall be superior and prior to the rights of
         all third Persons now existing or hereafter arising.

                  (e) Description of Pledged Interests. The Pledged Interests
         constitute all of the issued and outstanding shares of stock of the
         Companies and there are no outstanding warrants, options or other
         rights to purchase, or other agreements outstanding with respect to, or
         property that is now or hereafter convertible into, or that requires
         the issuance or sale of, any Pledged Interests.

                  (f) Margin Regulations. The pledge of the Pledged Collateral
         pursuant to this Agreement does not violate Regulation T, U or X of the
         Board of Governors of the Federal Reserve System.

                  (g) Other Information. All information heretofore, herein or
         hereafter supplied to Lender by or on behalf of Borrower with respect
         to Borrower or the Pledged Collateral is accurate and complete in all
         material respects.

         SECTION 5. Transfers and Other Liens; Additional Pledged Collateral,
etc. Borrower shall:

                  (a) not, without the prior written consent of Lender, (i)
         sell, assign (by operation of law or otherwise) or otherwise dispose
         of, or grant any option with respect to, any of the Pledged Collateral,
         (ii) create or suffer to exist any Lien upon or with respect to any of
         the Pledged Collateral, except for the security interest under this
         Agreement, or (iii) permit any issuer of Pledged Interests to merge or
         consolidate;

PLEDGE AGREEMENT - Page 3

<PAGE>

                  (b) (i) cause each issuer of Pledged Interests not to issue
         any stock or other securities in addition to or in substitution for the
         Pledged Interests issued by such issuer, except to Borrower, and (ii)
         pledge hereunder, immediately upon its acquisition (directly or
         indirectly) thereof, any and all additional shares of stock or other
         securities of each issuer of Pledged Interests and any certificates or
         other instruments hereafter delivered which are described in Section
         1(b) of this Agreement;

                  (c) promptly deliver to Lender all written notices received by
         it with respect to the Pledged Collateral; and

                  (d) pay promptly when due all taxes, assessments and
         governmental charges or levies imposed upon, and all claims against,
         the Pledged Collateral, except to the extent the validity thereof is
         being contested in good faith and adequate reserves therefor have been
         established in accordance with generally accepted accounting
         principles; provided that Borrower shall in any event pay such taxes,
         assessments, charges, levies or claims not later than five days prior
         to the date of any proposed sale under any judgment, writ or warrant of
         attachment entered or filed against Borrower or any of the Pledged
         Collateral as a result of the failure to make such payment.

         SECTION 6.  Further Assurances; Pledge Amendments; Covenants.

                  (a) Borrower agrees that from time to time, at the expense of
         Borrower, Borrower will promptly execute and deliver all further
         instruments and documents, and take all further action, that may be
         necessary or desirable, or that Lender may request, in order to perfect
         and protect any security interest granted or purported to be granted
         hereby or to enable Lender to exercise and enforce its rights and
         remedies hereunder with respect to any Pledged Collateral. Without
         limiting the generality of the foregoing, Borrower will: (i) execute
         and file such financing or continuation statements, or amendments
         thereto, and such other instruments or notices, as may be necessary or
         desirable, or as Lender may request, in order to perfect and preserve
         the security interests granted or purported to be granted hereby and
         (ii) at Lender's request, appear in and defend any action or proceeding
         that may affect Borrower's title to or Lender's security interest in
         all or any part of the Pledged Collateral.

                  (b) Borrower further agrees that it will, upon obtaining any
         additional shares of stock or other securities required to be pledged
         hereunder as provided in Section 5(b) of this Agreement, promptly (and
         in any event within five Business Days) deliver to Lender a Pledge
         Amendment, duly executed by Borrower, in substantially the form of
         Schedule II annexed hereto (a "Pledge Amendment"), in respect of the
         additional certificates or instruments to be pledged pursuant to this
         Agreement. Borrower hereby authorizes Lender to attach each Pledge
         Amendment to this Agreement and agrees that all certificates or
         instruments listed on any Pledge Amendment delivered to Lender shall
         for all purposes hereunder be considered Pledged Collateral; provided
         that the failure of Borrower to execute a Pledge Amendment with respect
         to any additional certificates or instruments pledged pursuant to this
         Agreement shall not impair the security interest of Lender therein or
         otherwise adversely affect the rights and remedies of Lender hereunder
         with respect thereto.

PLEDGE AGREEMENT - Page 4

<PAGE>

                  (c) Borrower will give Lender thirty (30) days prior written
         notice of any change in Borrower's name, identity or corporate
         structure.

                  (d) Borrower will give Lender thirty (30) days prior written
         notice of any change in the location of its chief executive office and
         will execute such documentation and take such actions as Lender deems
         necessary to perfect and protect the security interests granted hereby.

         SECTION 7.  Voting Rights; Dividends; Etc.

                  (a) So long as no Event of Default shall have occurred and be
         continuing:

                  (i) Borrower shall be entitled to exercise any and all voting
         and other rights pertaining to the Pledged Collateral or any part
         thereof for any purpose not inconsistent with the terms of this
         Agreement or the Loan Agreement; provided, however, that Borrower shall
         not exercise or refrain from exercising any such right if Lender shall
         have notified Borrower that, in Lender's reasonable judgment, such
         action would have a material adverse effect on the value of the Pledged
         Collateral or any part thereof. It is understood, however, that neither
         (A) the voting by Borrower of any Pledged Interests for or Borrower' s
         consent to the election of directors at a regularly scheduled annual or
         other meeting of stockholders or with respect to incidental matters at
         any such meeting nor (B) Borrower's consent to or approval of any
         action otherwise permitted under this Agreement and under the Loan
         Agreement shall be deemed inconsistent with the terms of this Agreement
         within the meaning of this Section 7(a)(i), and no notice of any such
         voting or consent need be given to Lender.

                  (ii) Borrower shall be entitled to receive and retain, and to
         utilize free and clear of the lien of this Agreement, any and all
         dividends, distributions, interest or other amounts paid in respect of
         the Pledged Collateral; provided, however, that any and all

                           (A) dividends, distributions, interest or other
                  amounts paid or payable other than in express compliance with
                  the provisions of the Loan Agreement in respect of any Pledged
                  Collateral,

                           (B) dividends, distributions, interest and other
                  amounts paid or payable other than in cash in respect of, and
                  instruments and other property received, receivable or
                  otherwise distributed in respect of, or in exchange for, any
                  Pledged Collateral,

                           (C) dividends and other distributions paid or payable
                  in cash and/or in property in respect of any Pledged
                  Collateral in connection with a partial or total liquidation
                  or dissolution or in connection with a reduction of capital,
                  capital surplus or paid-in-surplus, and

                           (D) cash or property paid, payable or otherwise
                  distributed in respect of principal of or in redemption of or
                  in exchange for any Pledged Collateral,

PLEDGE AGREEMENT - Page 5

<PAGE>

         in each case shall be, and shall forthwith be delivered to Lender to
         hold as, Pledged Collateral and shall, if received by Borrower, be
         received in trust for the benefit of Lender, be segregated from the
         other property or funds of Borrower and be forthwith delivered to
         Lender as Pledged Collateral in the same form as so received (with all
         necessary endorsements).

                  (iii) Lender shall promptly execute and deliver (or cause to
         be executed and delivered) to Borrower all such proxies, dividend
         payment orders and other instruments as Borrower may from time to time
         reasonably request for the purpose of enabling Borrower to exercise the
         voting and other rights which it is entitled to exercise pursuant to
         paragraph (i) above and to receive the dividends, distributions,
         principal, interest or other payments which it is authorized to receive
         and retain pursuant to paragraph (ii) above.

                  (b) Upon the occurrence and during the continuation of an
         Event of Default:

                  (i) Upon written notice from Lender to Borrower, all rights of
         Borrower to exercise the voting and other rights which it would
         otherwise be entitled to exercise pursuant to Section 7(a)(i) of this
         Agreement shall cease, and all such rights shall thereupon become
         vested in Lender who shall thereupon have the sole right to exercise
         such voting and other rights.

                  (ii) All rights of Borrower to receive the payments which it
         would otherwise be authorized to receive and retain pursuant to Section
         7(a)(ii) of this Agreement shall cease, and all such rights shall
         thereupon become vested in Lender who shall thereupon have the sole
         right to receive and hold as Pledged Collateral such payments.

                  (iii) All dividends, distributions, principal, interest and
         other payments which are received by Borrower contrary to the
         provisions of paragraph (ii) of this Section 7(b) shall be received in
         trust for the benefit of Lender, shall be segregated from other funds
         of Borrower and shall forthwith be paid over to Lender as Pledged
         Collateral in the same form as so received (with any necessary
         endorsements).

                  (c) In order to permit Lender to exercise the voting and other
         rights which it may be entitled to exercise pursuant to Section 7(b)(i)
         of this Agreement and to receive all dividends and other distributions
         which it may be entitled to receive under Section 7(a)(ii) of this
         Agreement or Section 7(b)(ii) of this Agreement, Borrower shall
         promptly execute and deliver (or cause to be executed and delivered) to
         Lender all such proxies, dividend payment orders and other
         documentation as Lender may from time to time reasonably request.

         SECTION 8. Lender Appointed Attorney-in-Fact. Borrower hereby
irrevocably appoints Lender as Borrower' s attorney-in-fact, with full authority
in the place and stead of Borrower and in the name of Borrower, Lender or
otherwise, from time to time in Lender's discretion to take any action and to
execute any instrument that Lender may deem necessary or advisable to accomplish
the purposes of this Agreement, including without limitation:

                  (a) to file one or more financing or continuation statements,
         or amendments thereto, relative to all or any part of the Pledged
         Collateral without the signature of Borrower;

                  (b) after the occurrence and during the continuance of an
         Event of Default, to ask, demand, collect, sue for, recover, compound,
         receive and give acquittance and receipts for moneys due and to become
         due under or in respect of any of the Pledged Collateral which are of
         the type described in Sections 7(a)(ii)(A) through (D) of this
         Agreement, and to ask, demand, collect, sue for, recover, compound,
         receive and give acquittance and receipts for any other type of money
         due and to become due under or in respect of any of the Pledged
         Collateral;

                  (c) after the occurrence and during the continuance of an
         Event of Default, to receive, endorse, and collect any instruments made
         payable to Borrower representing any dividend, distribution, principal,
         interest or other payment or distribution in respect of the Pledged
         Collateral of the type described in Sections 7(a)(ii)(A) through (D) of
         this Agreement, or any part thereof, and to give full discharge for the
         same and to receive, endorse and collect any instruments made payable
         to Borrower representing any other type of dividend, distribution,
         principal, interest or other payment or distribution in respect of the
         Pledged Collateral or any part thereof and to give full discharge for
         the same; and

                  (d) after the occurrence and during the continuance of an
         Event of Default, to file any other claims or take any other action or
         institute any other proceedings that Lender may deem necessary or
         desirable for the collection of any of the Pledged Collateral or
         otherwise to enforce the rights of Lender with respect to any of the
         Pledged Collateral.

         SECTION 9. Lender May Perform. If Borrower fails to perform any
agreement contained herein, Lender may itself perform, or cause performance of,
such agreement, and the expenses of Lender incurred in connection therewith
shall be payable by Borrower under Section 13(b) of this Agreement.

         SECTION 10. Standard of Care. The powers conferred on Lender hereunder
are solely to protect its interest in the Pledged Collateral and shall not
impose any duty upon it to exercise any such powers. Except for the exercise of
reasonable care in the custody of any Pledged Collateral in its possession and
the accounting for moneys actually received by it hereunder, Lender shall have
no duty as to any Pledged Collateral, it being understood that Lender shall have
no responsibility for (a) ascertaining or taking action with respect to calls,
conversions, exchanges, maturities, tenders or other matters relating to any
Pledged Collateral, whether or not Lender has or is deemed to have knowledge of
such matters, (b) taking any necessary steps (other than steps taken in
accordance with the standard of care set forth above to maintain possession of
the Pledged Collateral) to preserve rights against any parties with respect to
any Pledged Collateral, (c) taking any necessary steps to

PLEDGE AGREEMENT - Page 7

<PAGE>

collect or realize upon the Secured Indebtedness or any guarantee therefor, or
any part thereof, or any of the Pledged Collateral, or (d) initiating any action
to protect the Pledged Collateral against the possibility of a decline in market
value. Lender shall be deemed to have exercised reasonable care in the custody
and preservation of Pledged Collateral in its possession if such Pledged
Collateral is accorded treatment substantially equal to that which Lender
accords its own property of a similar nature.

         SECTION 11.  Remedies.

                  (a) If any Event of Default shall have occurred and be
         continuing, Lender may exercise in respect of the Pledged Collateral,
         in addition to all other rights and remedies provided for herein or
         otherwise available to it, all the rights and remedies of a Lender on
         default under the Uniform Commercial Code as in effect in any relevant
         jurisdiction (the "Code") (whether or not the Code applies to the
         affected Pledged Collateral), and Lender may also in its sole
         discretion, without notice except as specified below, sell the Pledged
         Collateral or any part thereof in one or more parcels at public or
         private sale, at any exchange or broker's board or at any of Lender's
         offices or elsewhere, for cash, on credit or for future delivery, at
         such time or times and at such price or prices and upon such other
         terms as Lender may deem commercially reasonable, irrespective of the
         impact of any such sales on the market price of the Pledged Collateral.
         Lender may be the purchaser of any or all of the Pledged Collateral at
         any such sale and shall be entitled, for the purpose of bidding and
         making settlement or payment of the purchase price for all or any
         portion of the Pledged Collateral sold at any such public sale, to use
         and apply any of the Secured Indebtedness as a credit on account of the
         purchase price for any Pledged Collateral payable by Lender at such
         sale. Each purchaser at any such sale shall hold the property sold
         absolutely free from any claim or right on the part of Borrower, and
         Borrower hereby waives (to the extent permitted by applicable law) all
         rights of redemption, stay and/or appraisal which it now has or may at
         any time in the future have under any rule of law or statute now
         existing or hereafter enacted. Borrower agrees that, to the extent
         notice of sale shall be required by law, at least ten days' notice to
         Borrower of the time and place of any public sale or the time after
         which any private sale is to be made shall constitute reasonable
         notification. Lender shall not be obligated to make any sale of Pledged
         Collateral regardless of notice of sale having been given. Lender may
         adjourn any public or private sale from time to time by announcement at
         the time and place fixed therefor, and such sale may, without further
         notice, be made at the time and place to which it was so adjourned.
         Borrower hereby waives any claims against Lender arising by reason of
         the fact that the price at which any Pledged Collateral may have been
         sold at such a private sale was less than the price which might have
         been obtained at a public sale, even if Lender accepts the first offer
         received and does not offer such Pledged Collateral to more than one
         offeree. If the proceeds of any sale or other disposition of the
         Pledged Collateral are insufficient to pay all the Secured
         Indebtedness, Borrower shall be liable for the deficiency and the
         reasonable fees of any attorneys employed by Lender to collect such
         deficiency.

                  (b) Borrower recognizes that, by reason of certain
         prohibitions contained in the Securities Act of 1933, as from time to
         time amended (the "Securities Act"), and applicable state securities
         laws, Lender may be compelled, with respect to any sale of all or any
         part of

PLEDGE AGREEMENT - Page 8

<PAGE>

         the Pledged Interests conducted without prior registration or
         qualification of such Pledged Interests under the Securities Act and/or
         such state securities laws, to limit purchasers to those who will
         agree, among other things, to acquire the Pledged Interests for their
         own account, for investment and not with a view to the distribution or
         resale thereof. Borrower acknowledges that any such private sales may
         be at prices and on terms less favorable to Lender than those
         obtainable through a public sale without such restrictions (including,
         without limitation, a public offering made pursuant to a registration
         statement under the Securities Act) and, notwithstanding such
         circumstances, Borrower agrees that any such private sale shall be
         deemed to have been made in a commercially reasonable manner and that
         Lender shall have no obligation to engage in public sales and no
         obligation to delay the sale of any Pledged Interests for the period of
         time necessary to permit the issuer thereof to register it for a form
         of public sale requiring registration under the Securities Act or under
         applicable state securities laws, even if such issuer would, or should,
         agree to so register it.

                  (c) If Lender determines to exercise its right to sell any or
         all of the Pledged Interests, upon written request, Borrower shall and
         shall cause each issuer of any Pledged Interests to be sold hereunder
         from time to time to furnish to Lender all such information as Lender
         may reasonably request in order to determine the number of shares and
         other instruments included in the Pledged Interests which may be sold
         by Lender in exempt transactions under the Securities Act and the rules
         and regulations of the Securities and Exchange Commission thereunder,
         as the same are from time to time in effect.

         SECTION 12. Application of Proceeds. Except as expressly provided
elsewhere in this Agreement, all proceeds received by Lender in respect of any
sale of, collection from, or other realization upon all or any part of the
Pledged Collateral shall be applied by Lender in accordance with the provisions
of the Loan Agreement.

         SECTION 13.  Indemnity and Expenses.

                  (a) BORROWER AGREES TO INDEMNIFY LENDER FROM AND AGAINST ANY
         AND ALL CLAIMS, LOSSES AND LIABILITIES IN ANY WAY RELATING TO, GROWING
         OUT OF OR RESULTING FROM THIS AGREEMENT AND THE TRANSACTIONS
         CONTEMPLATED HEREBY (INCLUDING, WITHOUT LIMITATION, ENFORCEMENT OF THIS
         AGREEMENT), EXCEPT TO THE EXTENT SUCH CLAIMS, LOSSES OR LIABILITIES
         RESULT SOLELY FROM LENDER'S NEGLIGENCE, WILLFUL MISCONDUCT OR BREACH OF
         THE TERMS HEREOF AS FINALLY DETERMINED BY A COURT OF COMPETENT
         JURISDICTION.

                  (b) BORROWER WILL PAY TO LENDER UPON DEMAND THE AMOUNT OF ANY
         AND ALL COSTS AND EXPENSES, INCLUDING THE REASONABLE FEES AND EXPENSES
         OF ITS COUNSEL AND OF ANY EXPERTS AND AGENTS, THAT LENDER MAY INCUR IN
         CONNECTION WITH (I) THE ADMINISTRATION OF THIS AGREEMENT, (II) THE
         CUSTODY OR PRESERVATION OF, OR THE SALE OF, COLLECTION FROM, OR OTHER
         REALIZATION UPON, ANY OF THE PLEDGED COLLATERAL, (III) THE EXERCISE OR
         ENFORCEMENT OF ANY OF THE RIGHTS

PLEDGE AGREEMENT - Page 9

<PAGE>

         OF LENDER HEREUNDER, OR (IV) THE FAILURE BY BORROWER TO PERFORM OR
         OBSERVE ANY OF THE PROVISIONS HEREOF.

         SECTION 14. Continuing Security Interest. This Agreement shall create a
continuing security interest in the Pledged Collateral and shall (a) remain in
full force and effect until the indefeasible payment in full of all Secured
Indebtedness and the cancellation or termination of the commitment of Lender to
make Loan, (b) be binding upon Borrower, its successors and assigns, and (c)
inure, together with the rights and remedies of Lender hereunder, to the benefit
of Lender and its successors, transferees and assigns. Upon the indefeasible
payment in full of all Secured Indebtedness and the cancellation or termination
of the Commitments, the security interest granted hereby shall terminate and all
rights to the Pledged Collateral shall revert to Borrower. Upon any such
termination Lender will, at Borrower' s expense, execute and deliver to Borrower
such documents as Borrower shall reasonably request to evidence such termination
and Borrower shall be entitled to the return, upon its request and at its
expense, against receipt and without recourse to Lender, of so much of the
Pledged Collateral as shall not have been sold or otherwise applied pursuant to
the terms hereof.

         SECTION 15. Amendments; Etc. No amendment or waiver of any provision of
this Agreement, or consent to any departure by Borrower herefrom, shall in any
event be effective unless the same shall be in writing and signed by Lender, and
then such waiver or consent shall be effective only in the specific instance and
for the specific purpose for which it was given.

         SECTION 16. Notices. Any notice or other communication herein required
or permitted to be given shall be in writing and given in accordance with the
provisions of the Loan Agreement.

         SECTION 17. Failure or Indulgence Not Waiver; Remedies Cumulative. No
failure or delay on the part of Lender in the exercise of any power, right or
privilege hereunder shall impair such power, right or privilege or be construed
to be a waiver of any default or acquiescence therein, nor shall any single or
partial exercise of any such power, right or privilege preclude any other or
further exercise thereof or of any other power, right or privilege. All rights
and remedies existing under this Agreement are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

         SECTION 18. Action or Omission by Lender. Borrower hereby agrees that
the Liens of this Agreement are and shall remain in full force and effect until
payment in full of the Secured Indebtedness as fully and completely as if
Borrower had been the maker of the Notes irrespective of any circumstance or
occurrence which, if for any reason Borrower is deemed to be a surety or
guarantor of or with respect to all or any portion of the Secured Indebtedness,
might otherwise constitute a legal or equitable discharge of a surety or a
guarantor. Without limiting the generality of the foregoing, it is expressly
agreed by Borrower that Lender and/or any one or more of the Lenders may, in its
or their sole discretion, at any time and from time to time, with or without
consideration, and without notice to or authorization or consent from or
knowledge of Borrower, do or refrain from doing any one or more of the
following, in each case without releasing, diminishing, impairing, reducing or
in any way affecting the liability and the Indebtedness of Borrower hereunder:

                  (a) Extend the time for payment of all or any part of the
         Secured Indebtedness or renew all or any part of the Secured
         Indebtedness;

                  (c) Extend the time for the performance of or compliance with
         any covenant or agreement contained in any of the Loan Documents or in
         any other instrument, document or of writing at any time securing
         payment of the Notes or any of the Secured Indebtedness, or any part
         thereof, or waive or modify such performance or compliance;

                  (d) Accept other security for the payment of all or any
         portion of the Secured Indebtedness;

                  (e) Accept the guarantee of and/or the assumption or agreement
         to pay all or any portion of the Secured Indebtedness by any Person;

                  (f) Accelerate the maturity of the Secured Indebtedness, or
         any part thereof as provided herein or in any of the other Loan
         Documents;

                  (g) Modify, exchange, release, surrender, subordinate, allow
         substitution for, allow release of or otherwise deal with all or any
         part of any real property or tangible or intangible personal property
         at any time securing the payment or performance of all or any part of
         the Secured Indebtedness;

                  (h) Release or discharge any Person at any time so obligated
         from the obligation to pay all or any portion of the Secured
         Indebtedness or to perform any covenant or agreement under any of the
         Loan Documents or any other instrument, document or writing at any time
         evidencing, securing and/or guaranteeing the payment of all or any part
         of the Secured Indebtedness;

                  (i) Compromise, compound or settle with any Person at any time
         obligated to pay all or any portion of the Secured Indebtedness or to
         perform any covenant or agreement under any of the Loan Documents or
         any other instrument, document or writing at any time evidencing,
         securing and/or guaranteeing the payment of all or any part of the
         Secured Indebtedness on such terms as it may, in its sole discretion,
         determine;

                  (j) Enforce any and all of the rights or remedies of Lender
         under any of the Loan Documents or any other instrument, document,
         agreement or writing at any time evidencing, securing and/or
         guaranteeing payment of all or any part of the Secured Indebtedness, or
         otherwise existing at law or in equity, against all or any portion of
         any real property or tangible or intangible personal property at any
         time securing all or any portion of the Secured Indebtedness, or
         against Borrower or any other Person at any time obligated to pay all
         or any portion of the Secured Indebtedness or to perform any covenant
         or agreement under any of the Loan Documents or any other instrument,
         document or other writing at any time evidencing, securing and/or
         guaranteeing the payment of all or any portion of the Secured
         Indebtedness, or any one or more of the foregoing, jointly, severally
         or individually;

PLEDGE AGREEMENT - Page 11

<PAGE>

                  (k) Modify, amend, alter, supplement, change or terminate any
         of the Loan Documents or any other instrument, document or writing at
         any time evidencing, securing and/or guaranteeing the payment of all or
         any portion of the Secured Indebtedness, or any one or more of the
         provisions thereof, including the time, manner and place of payment of
         the indebtedness evidenced by the Notes, the rate of interest from time
         to time accruing thereon, and the amount of any installment payable
         thereunder; and

                  (l) Apply any moneys received, whether from Borrower or
         others, or from any collateral securing payment of all or any portion
         of the Secured Indebtedness, in payment of any part of the Secured
         Indebtedness in such manner upon the Secured Indebtedness (whether then
         due or not), as Lenders may, in their sole and exclusive discretion,
         determine, without in any way being required to marshall collateral or
         to apply all or any part of such moneys upon any particular part of the
         Secured Indebtedness;

it being expressly agreed that the Indebtedness of Borrower hereunder and the
Liens granted or created hereby are and shall be unconditional and absolute and
are and shall remain in full force and effect until payment in full of the
Secured Indebtedness. Nothing contained herein or in any of the Loan Documents
or in any other instrument, document or other writing at any time securing or
guaranteeing payment of the Secured Indebtedness, or any part thereof, and no
action taken or omitted to be taken by the Lender and/or any one or more of the
Lenders hereunder or otherwise taken or omitted to be taken by Lender and/or any
one or more of the Lenders shall in any way release, impair, diminish or affect
Indebtedness and liabilities of Borrower under this Agreement.

         SECTION 19. Express Waivers. Borrower hereby expressly waives, to the
fullest extent permitted by applicable law:

                  (a) Presentment for payment, demand for payment of all or any
         portion of the Secured Indebtedness or any installment thereof, protest
         and all notices (whether of demand, dishonor, non-payment,
         acceleration, intent to accelerate, or otherwise), with respect to the
         Secured Indebtedness;

                  (b) Diligence in collecting or in attempting to collect all or
         any part of the Secured Indebtedness and in the bringing of any suit or
         in the enforcing of any remedy;

                  (c) Notice of acceptance of this Agreement, notice of the
         incurring by Borrower or any other Person of all or any portion of the
         Secured Indebtedness, or of the failure of Borrower or any other Person
         to pay any of the Secured Indebtedness as they mature, or of any other
         occurrence or state of facts of any nature whatsoever;

                  (d) All rights to require Lender and/or any one or more of the
         Lenders (i) to proceed against Borrower or any other Person, (ii) to
         proceed against or exhaust any collateral at any time securing all or
         any part of the Secured Indebtedness, or (iii) to initiate or pursue
         any right or remedy it may now or hereinafter have against Borrower or
         any other Person;

PLEDGE AGREEMENT - Page 12

<PAGE>

                  (e) All defenses to sureties or guarantors at law or in equity
         other than the actual payment of indebtedness; and

                  (f) All defenses based upon questions as to the authenticity,
         validity, enforceability or legality of any of the Loan Documents or
         any instrument, document or other writing at any time evidencing or
         securing or guaranteeing all or any part of the Secured Indebtedness.

         SECTION 20. Regarding Collateral. It is specifically agreed that
neither Lender nor any Lender is or shall be required to retain, hold, protect,
exercise due care with respect to, perfect Liens or security interests in or
otherwise assure or safeguard any collateral or security of or for the Secured
Indebtedness. No exercise or nonexercise by Lender and/or any one or more of the
Lenders of any right or remedy of Lender and/or any one or more of the Lenders
shall in any way affect any of Borrower's Indebtedness hereunder or Lien of this
Agreement or give Borrower any recourse against Lender and/or any one or more of
the Lenders.

         SECTION 21. Dissolution, etc. The Indebtedness of Borrower hereunder
and the Liens of this Agreement shall continue notwithstanding the incapacity,
death, disability, dissolution or termination of any other Person. The failure
by Lender and/or any one or more of the Lenders to file or enforce a claim
against the estate (either in probate, administration, bankruptcy or other
proceeding) of such other Person shall not affect the liability of Borrower
hereunder nor shall Borrower be released from liability if recovery from any
other Person becomes barred by any statute of limitations or is otherwise
prevented.

         SECTION 22. Direct Recourse. Neither Lender nor any Lender shall be
required to pursue any other remedy before invoking the benefits of this
Agreement, and specifically neither Lender nor any Lender shall be required to
exhaust its remedies against any other Person or to proceed against any security
now or hereafter existing for the payment of any of the Secured Indebtedness. If
judicial action is instituted under this Agreement, such action may be
maintained by Lender and/or any one or more of the Lenders whether or not any
other Person is joined therein and whether or not separate action is brought
against any other Person liable for payment of all or any portion of the Secured
Indebtedness.

         SECTION 23. Ultra Vires. If all or any portion of the Secured
Indebtedness exceeds any amount permitted by law, or should any Person not be
liable for the payment of all or any portion of the Secured Indebtedness because
the creation of all or any portion of the Secured Indebtedness is ultra vires or
the officers creating the same acted in excess of their authority and for these
reasons all or any portion of the Secured Indebtedness cannot be enforced
against such Person, such facts shall in no manner affect the Indebtedness of
Borrower hereunder or the Liens of this Agreement.

         SECTION 24. Severability. In case any provision in or obligation under
this Agreement shall be invalid, illegal or unenforceable in any jurisdiction,
the validity, legality and enforceability of the remaining provisions or
Indebtedness, or of such provision or obligation in any other jurisdiction,
shall not in any way be affected or impaired thereby.

         SECTION 25. Headings. Section and subsection headings in this Agreement
are included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purpose or be given any substantive effect.

         SECTION 26. Governing Law; Terms. THIS AGREEMENT SHALL BE GOVERNED BY,
AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE
STATE OF TEXAS EXCEPT AS REQUIRED BY MANDATORY PROVISION OF LAW AND EXCEPT TO
THE EXTENT THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST HEREUNDER,
OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR PLEDGED COLLATERAL ARE
GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF TEXAS.

         SECTION 27. Counterparts. This Agreement may be executed in one or more
counterparts and by different parties hereto in separate counterparts, each of
which when so executed and delivered shall be deemed an original, but all such
counterparts together shall constitute but one and the same instrument;
signature pages may be detached from multiple separate counterparts and attached
to a single counterpart so that all signature pages are physically attached to
the same document.
