subject to the terms and conditions herein set forth, such amount to Borrower.
Such borrowings shall be evidenced by one or more Senior Secured Promissory
Notes (each, a "Note" and collectively, the "Notes"), in the form attached

     B. As security for Borrower's obligations to Lender under this Security
Agreement, the Notes and any other agreement between Borrower and Lender,

            ---------------------------

     Borrower shall pay to Lender, at its office at the address specified in the
Notes, or such other address as Lender specifies in writing, all amounts payable
to it in respect of the principal of or interest on the Notes.

SECTION 5.  AFFIRMATIVE COVENANTS REGARDING THE COLLATERAL.
            ----------------------------------------------

     Borrower covenants and agrees that so long as any portion of the
Indebtedness is unpaid and as long as any of the Obligations are outstanding it
will comply with the following covenants:

     (a) Location; Inspection. All of the Collateral shall be located at the
         --------------------
address (the "Collateral Location") shown on the Schedule 1 to each Note and
shall not be moved without Lender's prior written consent unless held
temporarily off site under Borrower's strict supervision and control. All of the
records regarding the Collateral shall be located at 4200 Six Forks Road,
Raleigh, NC 27609. Lender shall have the right to inspect Collateral, including
records relating thereto, and Borrower's books and records at any time (upon
reasonable notification) during regular business hours, such books and records
to be maintained in accordance with generally accepted accounting principles.
Borrower shall be responsible for all labor, material and freight charges
incurred in connection with any removal or relocation of Collateral which is
requested by Borrower and consented to by Lender, as well as for any charges due
to the installation or moving of the Collateral. Payments under the Notes and
under this Security Agreement shall continue during any period in which the
Collateral is in transit during a relocation. Lender or its agent shall mark and
label Collateral, which labels (to be provided by Lender) shall state that such
Collateral is subject to a security interest of Lender, and Borrower shall keep
such labels on the Collateral as so labeled.

     (b) Collateral Maintenance. Borrower will reasonably permit Lender to
         ----------------------
inspect such item of Collateral and its maintenance records. Borrower will at
its sole expense comply with all applicable laws, rules, regulations,
requirements and orders with respect to the use, maintenance, repair, condition,
storage and operation of each item of Collateral. Except as required herein,
Borrower will not make any addition or improvement to any item of Collateral
that is not readily removable without causing material damage to any item or
impairing its original value or utility. Any addition or improvement that is so
required or cannot be so removed will immediately become Collateral of Lender.

     (c) Service and Repair. Borrower will at its sole expense maintain and
         ------------------
service and repair each item of Collateral in a manner consistent with prudent
industry practice and Borrower's own practice so that such item of Collateral is
at all times (i) in the same condition as when delivered to Borrower, except for
ordinary wear and tear, and (ii) in good operating order for the function
intended by its manufacturer's warranties and recommendations.

                                      -3-
<PAGE>

     (d) Loss or Damage. Borrower assumes the entire risk of loss to the
         --------------
Collateral through use, operation or otherwise. Borrower hereby indemnifies and
holds harmless Lender from and against all claims, loss of Loan payments, costs,
damages, and expenses relating to or resulting from any loss, damage or
destruction of the Collateral, any such occurrence being hereinafter called a
"Casualty Occurrence." Following a Casualty Occurrence, Borrower shall, thirty
(30) days after such Casualty Occurrence, pay to Lender an amount equal to the
Balance Due (as defined below) for each item of Collateral. The Balance Due for
each item is the sum of: (i) all amounts for each item which may be then due or
accrued to the payment date, plus (ii) as of such payment date, an amount equal
to the product of the fraction specified below times the sum of all remaining
payments under the respective Note, including the amount of any mandatory or
optional payment required or permitted to be paid by Borrower to Lender at the
maturity of the Note. The numerator of the fraction shall be the Collateral
Value (as set forth on the applicable schedule) of the item and the denominator
shall be the aggregate Collateral Value of all items under the Note. Upon the
making of such payments, Lender shall release such item of Collateral from its
lien hereunder.

     Notwithstanding the above, within thirty (30) days following a Casualty
Occurrence, Borrower may replace any item of Collateral which has suffered a
Casualty Occurrence with Collateral acceptable to Lender in its complete
discretion and, in such event, the provisions of the previous paragraph shall
not apply. Borrower's tender of such Collateral shall constitute a
representation and warranty that it is free of all liens, claims and
encumbrances, and otherwise qualifies as Collateral under this Security
Agreement. Following such tender, Lender shall have a first security interest in
such Collateral.

     (e) Insurance. Borrower at its expense shall keep the Collateral insured
         ---------
against all risks for the value of the Collateral and in no event for less than
the amount payable following a Casualty Event (as provided in Section 5(d)).
Such insurance shall provide for (i) property damage insurance naming Lender or
any assignee as loss payee and (ii) public liability coverage naming Lender as
an additional insured or any assignee in an amount not less than $1,000,000 per
occurrence, with a $2,000,000 cap. Borrower will provide Lender and any assignee
of Lender with a certificate of insurance from the insurer evidencing Lender's
or such assignee's interest in the policy of insurance. Such insurance shall
cover any Casualty Occurrence to any unit of Collateral. Notwithstanding
anything in Section 5(d) or this Section 5(e) to the contrary, this Security
Agreement and Borrower's obligations hereunder shall remain in full force and
effect with respect to any unit of Collateral which is not subject to a Casualty
Occurrence.

SECTION 6.  MISCELLANEOUS AFFIRMATIVE COVENANTS.
            -----------------------------------

     So long as any portion of the Indebtedness is unpaid and as long as any of
the Obligations are outstanding Borrower will:

     (a) duly pay all governmental taxes and assessments at the time they become
due and payable;

     (b) comply with all applicable governmental laws, rules and regulations;

     (c) maintain Lender's security interest in the Collateral as a first and
prior perfected security interest;

     (d) furnish Lender with its annual audited financial statements within
ninety (90) days following the end of Borrower's fiscal year and within thirty
(30) days of the

                                      -4-
<PAGE>

end of each month a financial statement for that month prepared by Borrower, all
of which shall be certified by an officer of Borrower as true and correct and
shall be prepared in accordance with generally accepted accounting principles
consistently applied, and such other information as Lender may reasonably
request;

     (e) promptly (but in no event more than five (5) days after the occurrence
of such event) notify Lender of any material adverse change in Borrower's
condition during the commitment period and of the occurrence of any Event of
Default; and

     (f) take all steps deemed by Lender reasonable or advisable to validate or
perfect the security interest of Lender in the Collateral.

SECTION 7.  INDEMNITIES.
            -----------

     (a) General. Borrower will protect, indemnify and save harmless Lender and
         -------
any assignees on an after-tax basis from and against all liabilities,
obligations, claims, damages, penalties, causes of action, costs and expenses
(including reasonable attorneys' fees and expenses), imposed upon or incurred by
or asserted against Lender or any assignee of Lender by Borrower or any third
party by reason of the occurrence or existence (or alleged occurrence or
existence) of any act or event relating to or caused by any portion of the

transportation, including without limitation, consequential or special damages
of any kind, any failure on the part of Borrower to perform or comply with any
of the terms of this Security Agreement or the Notes, claims for latent or other
defects, claims for patent, trademark or copyright infringement and claims for
personal injury, death or property damage, including those based on Lender's
negligence or strict liability in tort and excluding only those based on
Lender's gross negligence or willful misconduct. In the event that any action,
suit or proceeding is brought against Lender by reason of any such occurrence,
Borrower, upon Lender's request, will, at Borrower's expense, resist and defend
such action, suit or proceeding or cause the same to be resisted and defended by
counsel designated by Lender.

     (b) Tax Indemnity. Borrower agrees to reimburse Lender (or pay directly if
         -------------
instructed by Lender) and any assignee of Lender for, and to indemnify and hold
Lender and any assignee harmless from, all fees (including, but not limited to,
license, documentation, recording and registration fees), and all sales, use,
gross receipts, personal property, occupational, value added or other taxes,
levies, imposts, duties, assessments, charges, or withholdings of any nature
whatsoever, together with any penalties, fines, additions to tax, or interest
thereon (the foregoing collectively "Impositions"), except same as may be
attributable to Lender's income, arising at any time prior to or during the term
of any Notes or of this Security Agreement, or upon termination or early
termination of this Security Agreement and levied or imposed upon Lender
directly or otherwise by any Federal, state or local government in the United
States or by any foreign country or foreign or international taxing authority
upon or with respect to (i) the Collateral, (ii) the exportation, importation,
registration, purchase, ownership, delivery, leasing, possession, use,
operation, storage, maintenance, repair, return, sale, transfer of title, or
other disposition thereof, (iii) the rentals, receipts, or earnings arising from
the Collateral, or any disposition of the rights to such rentals, receipts, or
earnings, (iv) any payment pursuant to this Security Agreement or the Notes, or
(v) this Security Agreement, the Notes or any transaction or any part hereof or
thereof.

     (c) Survivability. Borrower's obligations under this Section 7 shall
         -------------
survive the payment in full of all the Indebtedness and the performance of all
Obligations with

                                      -5-
<PAGE>

respect to acts or events occurring or alleged to have occurred prior to the
payment in full of all the Indebtedness and the performance of all Obligations.

SECTION 8.  RELEASE OF LIENS.
            ----------------

     Upon payment of all of the Indebtedness and performance of all of the
Obligations, Lender shall execute UCC termination statements and such other
documents as Borrower shall reasonably require to evidence the release of
Lender's lien relating to the Collateral.

SECTION 9.  ASSIGNMENT.
            ----------

     WITHOUT LENDER'S PRIOR WRITTEN CONSENT, BORROWER SHALL NOT (a) ASSIGN,
TRANSFER, PLEDGE, HYPOTHECATE OR OTHERWISE DISPOSE OF THIS SECURITY AGREEMENT,
ANY COLLATERAL, OR ANY INTEREST THEREIN, (b) LEASE OR LEND COLLATERAL OR PERMIT
IT TO BE USED BY ANYONE OTHER THAN BORROWER OR BORROWER'S EMPLOYEES, AGENTS,
CONTRACTORS, CONSULTANTS AND CUSTOMERS ALL UNDER CLOSE SUPERVISION AND CONTROL,
OR (c) MERGE INTO, CONSOLIDATE WITH OR CONVEY OR TRANSFER ITS PROPERTIES
SUBSTANTIALLY AS AN ENTIRETY TO ANY OTHER PERSON OR ENTITY. Lender may assign
any of the Notes, this Security Agreement or its security interest in any or all
Collateral, or any or all of the above, in whole or in part to one or more
assignees or secured parties without notice to Borrower. If Borrower is given
notice of such assignment it agrees to acknowledge receipt thereof in writing
and Borrower shall execute such additional documentation as Lender's assignee
shall reasonably require. Each such assignee and/or secured party shall have all
of the rights, but (except as provided in Section 9 hereof) none of the
obligations, of Lender under this Security Agreement, unless it expressly agrees
to assume such obligations in writing. Borrower shall not assert against any
assignee and/or secured party any defense, counterclaim or offset that Borrower
may have against Lender. Notwithstanding any such assignment, and providing no
Event of Default has occurred and is continuing, Lender, or its assignees,
secured parties, or their agents or assigns, shall not interfere with Borrower's
right to quietly enjoy use of Collateral subject to the terms and conditions of
this Security Agreement. Subject to the foregoing, the Notes and this Security
Agreement shall inure to the benefit of, and are binding upon, the successors
and assignees of the parties hereto.

SECTION 10.  DEFAULT.
             -------

     (a) Events of Default. Any of the following events or conditions shall
         -----------------
constitute an "Event of Default" hereunder: (i) Borrower's failure to pay any
monies due to Lender hereunder or under any Note beyond the tenth (10th) day
after the same is due; (ii) Borrower's failure to comply with its obligations
under Section 5(e) or Section 9; (iii) any representation or warranty of
Borrower made in this Security Agreement or the Notes or in any other agreement,
statement or certificate furnished to Lender in connection with this Security
Agreement or the Notes shall prove to have been incorrect in any material
respect when made or given; (iv) Borrower's failure to comply with or perform
any term, covenant or condition of this Security Agreement or any Note or under
any other agreement between Borrower and Lender or under any lease of real
property covering the location of the Equipment if such failure to comply or
perform is not cured by Borrower within five (5) days after Borrower knows of
the noncompliance or nonperformance or notice from Lender; (v) seizure of any of
the Collateral under legal process; (vi) the filing by or against Borrower or
any guarantor under any guaranty executed in connection with this Security
Agreement ("Guarantor") of a petition for reorganization or liquidation under
the Bankruptcy Code or any amendment thereto or under any other insolvency law
providing for the relief of debtors; (vii) the voluntary or involuntary making
of an assignment of a substantial portion of its assets by Borrower or by any
Guarantor for the benefit of its creditors, the appointment of a receiver or
trustee for Borrower or any Guarantor or for

                                      -6-
<PAGE>

any of Borrower's or Guarantor's assets, the institution by or against Borrower
or any Guarantor of any formal or informal proceeding for dissolution,
liquidation, settlement of claims against or winding up of the affairs of
Borrower or any Guarantor provided that in the case of all such involuntary
proceedings, same are not dismissed within sixty (60) days after commencement;
(viii) the making by Borrower or by any Guarantor under any Guaranty executed in
connection with this Loan of a transfer of all or a material portion of
Borrower's or Guarantor's assets or inventory not in the ordinary course of
business.

     (b) Remedies. If any Event of Default has occurred, Lender may in its sole
         --------
discretion exercise one or more of the following remedies with respect to any or
all of the Collateral: (i) declare due any or all of the aggregate sum of all
remaining payments under the Notes, including the amount of any mandatory or
optional payment required or permitted to be paid by Borrower to Lender at the
maturity of the Notes ("Remaining Payments"); (ii) proceed by court action to
enforce Borrower's performance of the Notes and this Security Agreement or to
recover all damages and expenses incurred by Lender by reason of an Event of
Default; (iii) without court order or prior demand, enter upon the premises
where the Collateral is located and take immediate possession of and remove it
without liability of Lender to Borrower or any other person or entity; (iv)
terminate this Security Agreement and sell the Collateral at public or private
sale, or otherwise dispose of, hold, use or lease any or all of the Collateral;
or (v) exercise any other right or remedy available to it under applicable law.
If Lender has declared due any or all of the Remaining Payments, Borrower will
pay immediately to Lender (a) the Remaining Payments, (b) all amounts which may
be then due or accrued, and (c) all other amounts due under this Security
Agreement and under the Notes (Lender's Return, as referred to below, means the
amounts described in clauses (a), (b) and (c) above). The net proceeds of any
sale or lease of such Collateral will be credited against Lender's Return. The
net proceeds of a sale of the Collateral pursuant to this Section 11(b) is
defined as the sales price of the Collateral less selling expenses, including,
without limitation, costs of remarketing the Collateral and all refurbishing
costs and commissions paid with respect to such remarketing. The net proceeds of
a lease of the Collateral pursuant to this Section 11(b) is defined as the
amount equal to the rental payments due under such lease (discounted at a rate
per annum equal to the discount rate for 13-week Treasury Bills as of the date
on which Lender notifies Borrower that this Security Agreement is terminated
(the "Termination Date") (as such rate is reported in the Money Rates column in
the Wall Street Journal) or the Termination Date or, if the Wall Street Journal
    -------------------                                     -------------------
is not published on such date or the next date after the Termination Date that
the Wall Street Journal is published (the "Discount Rate")) plus the residual
    -------------------
value of the Collateral at the end of the basic term of such lease, as
reasonably determined by Lender, and discounted at the Discount Rate.

     In addition to the foregoing remedies, Lender may:

     Apply the security deposit pledged to Lender pursuant to Section 16,
including all interest paid thereon, (A) to compensate Lender for losses or
damages sustained as a result of such Event of Default; and/or (B) to reimburse
Lender for costs and expenses, including reasonable attorney's fees, incurred by
Lender in connection with such failure to perform, whether or not litigation or
other judicial proceedings are commenced. Any surplus remaining thereafter shall
be retained by Lender as security hereunder.

     Borrower agrees to pay all reasonable internal and out-of-pocket costs of
Lender incurred in enforcement of this Security Agreement, the Notes or any
instrument or agreement required under this Security Agreement, including, but
not limited to, direct overhead costs of Lender allocated to the estimated time
spent by its employees (and the employees of its affiliates, including counsel
who are employees of Lender or its affiliates) and outside counsel legal fees
and litigation expenses and fees of collection

                                     -7-
<PAGE>

agencies ("Remedy Expenses"). At Lender's request, Borrower shall assemble the
Collateral and make it available to Lender at such time and location as Lender
may designate. Borrower waives any right it may have to redeem the Collateral.

     Declaration that any or all amounts under this Security Agreement and/or
the Notes are immediately due and payable shall not terminate this Security
Agreement or any of the Notes unless Lender so notifies Borrower in writing.
Notwithstanding Section 11 herein, any amount required to be paid under this
section shall accrue interest at a rate of 23% per annum, or the highest rate of
interest permitted by applicable law, whichever is less, accruing from the date
the amounts are payable hereunder until such amounts are paid. All such remedies
are cumulative and may be enforced separately or concurrently.

     In addition to the foregoing remedies, if an Event of Default hereunder
shall have occurred and be continuing, Lender shall have the right to cause its
representative or representatives to attend any meeting of Borrower's Board of
Directors or any committee thereof. In such case, Borrower shall provide Lender
with the same notice of any such Board or committee meeting that is given to the
members of Borrower's Board or committee thereof.

     (c) Application of Proceeds. The proceeds of any sale of all or any part of
         -----------------------
the Collateral and the proceeds of any remedy afforded to Lender by this
Security Agreement shall be paid to and applied as follows:

     First, to the payment of reasonable costs and expenses of suit or
     -----
foreclosure, if any, and of the sale, if any, including, without limitation,
refurbishing costs, costs of remarketing and commissions related to remarketing,
all Remedy Expenses, all expenses, liabilities and advances incurred or made
pursuant to this Security Agreement or any Note by Lender in connection with
foreclosure, suit, sale or enforcement of this Security Agreement or the Notes,
and taxes, assessments or liens superior to Lender's security interest granted
by this Security Agreement;

     Second, to the payment of all other amounts not described in item Third
     ------                                                            -----
below due under this Security Agreement and all Notes;

     Third, to pay Lender an amount equal to Lender's Return, to the extent not
     -----
previously paid by Borrower; and

     Fourth, to the payment of any surplus to Borrower or to whomever may
     ------
lawfully be entitled to receive it.

     (d) Effect of Delay; Waiver; Foreclosure on Collateral. No delay or
         --------------------------------------------------
omission of Lender, in exercising any right or power arising from any Event of
Default shall prevent Lender from exercising that right or power if the Event of
Default continues. No waiver of an Event of Default, whether full or partial, by
Lender or such holder shall be taken to extend to any subsequent Event of
Default, or to impair the rights of Lender in respect of any damages suffered as
a result of the Event of Default. The giving, taking or enforcement of any other
or additional security, collateral or guaranty for the payment or discharge of
the Indebtedness and performance of the Obligations shall in no way operate to
prejudice, waive or affect the security interest created by this Security
Agreement or any rights, powers or remedies exercised hereunder or thereunder.
Lender shall not be required first to foreclose on the Collateral prior to

Agreement or under any Note.

SECTION 11.  LATE PAYMENTS.
             -------------

     Borrower shall pay Lender an amount equal to the greater of 5% of all
amounts owed Lender by Borrower which are not paid when due taking into account
applicable grace periods or $100, but in no event an amount greater than the
highest rate permitted by applicable law. If such amounts have not been received
by Lender at Lender's place of business or by Lender's designated agent by the
date such amounts are due under this Security Agreement or the Notes, Lender
shall bill Borrower for such charges. Borrower acknowledges that invoices for
amounts due hereunder or under the Notes are sent by Lender for Borrower's
convenience only. Borrower's non-receipt of an invoice will not relieve Borrower
of its obligation to make payments hereunder or under the Notes.

SECTION 12.  PAYMENTS BY LENDER.
             ------------------

     If Borrower shall fail to make any payment or perform any act required
hereunder (including, but not limited to, maintenance of any insurance required
by Section 5(e)), then Lender may, but shall not be required to, after such
notice to Borrower as is reasonable under the circumstances, make such payment
or perform such act with the same effect as if made or performed by Borrower.
Borrower will upon demand reimburse Lender for all sums paid and all costs and
expenses incurred in connection with the performance of any such act.

SECTION 13.  FINANCING STATEMENTS.
             --------------------

     Borrower will execute all financing statements pursuant to the Uniform
Commercial Code and all such other documents reasonably requested by Lender to
perfect Lender's security interests hereunder. Borrower authorizes Lender to
file financing statements signed only by Lender (where such authorization is
permitted by law) at all places where Lender deems necessary.

SECTION 14.  NATURE OF TRANSACTION.
             ---------------------

     Lender makes no representation whatsoever, express or implied, concerning
the legal character of the transaction evidenced hereby, for tax or any other
purpose.

SECTION 15  ADDITIONAL SECURITY.
            -------------------

     For each Note executed by Borrower hereunder, before Lender's funding of
the Note, Borrower shall provide to Lender, as security for the timely
performance and payment by Borrower of its obligations hereunder, cash in a
dollar amount equal to the last monthly payment amount ("Additional Security").
Provided (a) no Event of Default hereunder has occurred and is continuing, (b)
Lender is satisfied that Borrower has theretofore continuously performed
according to its Business Plan, and (c) Lender has timely received from Borrower
all Monthly Note Payments, then Lender shall apply the Additional Security to
Borrower's additional interest compensation election set forth in the Note.

If an Event of Default by Borrower occurs hereunder, the amount of the
Additional Security then retained by Lender, together with any interest thereon,
shall be applied against the amount of Borrower's default obligation. In such
event, Lender may apply all or part of the Additional Security for the following
purposes:

(a) to compensate Lender for losses or damages sustained as a result of such
Event of Default; and/or

                                      -9-
<PAGE>

(b) to reimburse Lender for costs and expenses, including reasonable attorney's
fees, incurred by Lender in connection with such failure to perform, whether or
not litigation or other judicial proceedings are commenced. Any surplus
remaining thereafter shall be retained by Lender as security hereunder. Provided
no Event of Default has occurred and is continuing under this Loan, upon payment
by Borrower of all obligations under the Note, any Additional Security, if any,
held by Lender for such Note shall be returned to Borrower.

SECTION 16.  COMMITMENT FEE.
             --------------

     Borrower has paid to Lender a commitment fee ("Fee") of $5,000.00. The Fee
shall be applied by Lender first to reimburse Lender for all out-of-pocket UCC
and other search costs, and all appraisal fees incurred by Lender, and then
proportionally to the first monthly payment for each Note hereunder in the
proportion that the Collateral Value for such Note bears to Lender's entire
commitment. However, the portion of the Fee which is not applied to such monthly
payments shall be non-refundable.

SECTION 17.  MISCELLANEOUS.
             -------------

     (a) Borrower shall provide Lender with such corporate resolutions,
financial statements, opinions of counsel and other documents as Lender shall
reasonably request from time to time. (b) Borrower represents that the
Collateral hereunder is used solely for business purposes. (c) Time is of the
essence with respect to this Security Agreement. (d) All notices hereunder shall
be in writing, sent by registered or certified mail, return receipt requested or
by reliable messenger or delivery service, and shall be directed, as the case
may be, to Lender at 2401 Kerner Boulevard, San Rafael, California 94901,
Attention: Lease Administration and to Borrower at 4200 Six Forks Road, Raleigh,
NC 27609, Attention: J. Nicholas Riehle. Such notices shall be effective on
receipt if delivered personally, five days after dispatch if mailed and one
business day after dispatch if sent by courier service. (e) Borrower
acknowledges that Borrower has read this Security Agreement and the Notes,
understands them and agrees to be bound by their terms and further agrees that
this Security Agreement and the Notes constitute the entire agreement between
Lender and Borrower with respect to the subject matter hereof and supersede all
previous agreements, promises, or representations. (f) This Security Agreement
and the Notes may not be changed, altered or modified except by an instrument
signed by an officer or authorized representative of Lender and Borrower. (g)
Any failure of Lender to require strict performance by Borrower or any waiver by
Lender of any provision herein or in a Note shall not be construed as a consent
or waiver of any other breach of the same or any other provision. (h) If any
provision of this Security Agreement or a Note is held invalid, such invalidity
shall not affect any other provisions hereof or thereof. (i) The obligations of
Borrower to pay the Indebtedness and perform the Obligations shall survive the
expiration or earlier termination of this Security Agreement or the Notes until
all Obligations of Borrower to Lender have been met and all liabilities of
Borrower to Lender and any assignee have been paid in full. (j) Borrower will
notify Lender at least 30 days before changing its name, principal place of
business or chief executive office. (k) Borrower will, at its expense, promptly
execute and deliver to Lender such documents and assurances (including financing
statements) and take such further action as Lender may reasonably request in
order to carry out the intent of this Security Agreement and Lender's rights and
remedies. (l) Borrower hereby appoints Lender (and each of Lender's officers,
employees or agents designated by Lender), with full power of substitution by
Lender, as Borrower's attorney, with power to execute and deliver on Borrower's
behalf financing statements and other documents necessary to perfect and/or give
notice of Lender's security interest in any of the Collateral.

SECTION 18.  JURISDICTION AND WAIVER OF JURY TRIAL.
             -------------------------------------

     This Security Agreement and the Notes shall be governed by and construed
under the laws of the State of California, excluding principles of conflicts of
laws. It is agreed that exclusive jurisdiction and venue for any legal action
between the parties arising out of or relating to this Security Agreement or a
Note shall be in the Superior Court for Marin County, California, or, in cases
where federal diversity jurisdiction is available, in the United States District
Court for the Northern District of California situated in San Francisco.
BORROWER, TO THE EXTENT IT MAY LAWFULLY DO SO, HEREBY WAIVES ITS RIGHT TO TRIAL
BY JURY IN ANY ACTION BROUGHT ON OR WITH RESPECT TO THIS SECURITY AGREEMENT, ANY
NOTE, ANY SECURITY DOCUMENTS, OR ANY OTHER AGREEMENTS EXECUTED IN CONNECTION
HEREWITH.

SECTION 19. END OF LOAN POSITION.
            --------------------

Provided no Event of Default has occurred and is continuing, Lender hereby
grants to Borrower the additional interest compensation options or requirements
("End of Loan Position") set forth in each Note. Borrower shall elect one of
such options or requirements by giving Lessor at least 90 days' written notice
thereof prior to the expiration of the initial term of the first Note to the
Loan which shall be an election of Borrower's End of Loan Position for all, but
not less than all, of the Collateral under all Notes to the Loan. Fair market
value shall be determined in a commercially reasonable manner by Lender for the
Collateral under all Notes prior to the first Note's expiration.

IN WITNESS WHEREOF, Borrower and Lender have caused this Security Agreement to
be executed as of the date and year first above written.

                                                         San Rafael, California

     FOR VALUE RECEIVED, the undersigned, HAHT SOFTWARE, INC., a North Carolina

interest on the decreasing balance of this principal amount until the principal
is fully repaid. Principal and interest shall be payable in consecutive monthly

Note. If Borrower fails to timely make the payment required under (a) above,
Borrower shall be deemed to have elected (b).

     Borrower shall pay to Lender an amount equal to the greater of 10% of all
amounts owed Lender by Borrower which are not paid when due or $100, but in no
event an amount greater than the highest rate permitted by applicable law.

     Payments of principal and interest hereunder shall be made in lawful money
of the United States of America at the offices of Lender at 2401 Kerner
