                        LIMITED RECOURSE PROMISSORY NOTE

$500,000.00                                                      August 13, 1999
                                                             Annandale, Virginia

         For value received, James W. MacIntyre, IV (the "Borrower") promises to
pay to OneSoft Corporation, a Delaware corporation (the "Lender") at the office
of Lender located at 7010 Little River Turnpike, Annandale, Virginia, or such
other place as the holder hereof shall designate by prior written notice to the
Borrower, on the third anniversary of the date hereof, as such date for payment
may be extended as hereinafter provided (as extended, if extended, the "Due
Date") the sum of $500,000.00, together with interest accruing to the Due Date
at the fixed rate of five and thirty-two one-hundredths percent (5.43%) per
annum or, if different on the date hereof, the Applicable Federal Rate (AFR) for
determining below-market interest rates for loans of such kind for purposes of
determining the taxability thereof under the Internal Revenue Code of 1986, as
amended, compounded annually; provided that recourse against the Borrower for
payment of this Limited Recourse Promissory Note ("this Note") or otherwise for
payment of the indebtedness represented hereby shall be limited exclusively to
recourse against the pledged collateral (the "Pledged Collateral") provided for
in the Pledge and Security Agreement of even date herewith to which the Borrower
and the Lender are parties and which secures payment of this Note (the "Pledge
Agreement") and the Borrower shall have no personal liability for or with
respect to the payment of this Note or such indebtedness, as to all of which the
Lender hereby holds the Borrower personally harmless except to the extent of
such exclusive recourse against the Pledged Collateral. Interest shall be
calculated on the basis of actual days elapsed and a 360-day year. All amounts
owing under this Note shall become immediately due and payable upon the
occurrence of an Event of Default. If there shall be an Event of Default and so
long as such Event of Default shall be continuing, interest on the unpaid
balance shall thereafter be payable on demand at a fluctuating rate per annum
equal to the greater of three percent in excess of the fixed rate stated above
and three percent in excess of the prime rate of interest as published in the
Wall Street Journal from time to time. This Note may be prepaid, as a whole or
in part, at any time and without penalty. For purposes of this Note, an "Event
of Default" shall mean (1) the failure of the Borrower to pay or otherwise
satisfy or cause to be paid or otherwise satisfied the principal of and interest
on this Note on the Due Date, (2) the voluntary filing by the Borrower of a
petition in bankruptcy or other action by the Borrower seeking the protection
from the Borrower's creditors under bankruptcy or insolvency laws, or (3) the
filing of an involuntary bankruptcy petition by creditors of the Borrower and
the failure of such petition to be dismissed, rescinded or otherwise rendered of
no further legal effect within sixty (60) days after filing.

         The Borrower hereby waives presentment, demand, notice, protest and all
other demands and notices in connection with the delivery, acceptance,
performance, default or enforcement hereof and consent that this Note may be
extended from time to time and that no such extension or other indulgence, and
no substitution, release or surrender of any of the Pledged Collateral shall
discharge or otherwise affect the recourse of the holder hereof against the
Pledged Collateral for payment of this Note. No delay or omission on the part of
the holder in exercising any right hereunder shall operate as a waiver of any
such right or of any other right hereunder

                                                                     /s/ FCH JWM
<PAGE>

and a waiver of any such right on any one occasion shall not be construed as a
bar to or waiver of any such right on any future occasion.

         Notwithstanding any other provision hereof or of the Pledge Agreement
to the contrary, the Due Date shall be extended to that date (which shall
thereupon become the Due Date), if any, which is later than the Due Date set
forth hereinabove and which is also the earlier of (1) earliest date following
the expiration of the 180-day period immediately following the date of
effectiveness of the registration statement filed with the Securities and
Exchange Commission for the Lender's initial public offering ("IPO") of its
equity securities in which gross proceeds to the Lender equal or exceed
$25,000,000.00 at an implied pre-IPO valuation of the Lender equaling or
exceeding $100,000,000.00 on which the Borrower shall be free of any and all
conditions, limitations or other restrictions (other than limitations under Rule
144 of the General Rules and Regulations of the Securities and Exchange
Commission) applicable to the public sale of shares of the Corporation's Common
Stock held by the Borrower, or (2) the earliest date coinciding with or
following the date on which (a) the Borrower receives cash or marketable
securities representing proceeds from the sale of the Lender or all or
substantially all of the Borrower's interest in the Lender, whether through a
sale of all or substantially all of the assets of the Lender, a merger, stock
sale or otherwise, or the dissolution of the Lender and (b) the Borrower shall
be free to dispose of such proceeds.

         This Note is not a negotiable instrument but may be assigned in writing
by the Lender or any subsequent holder hereof who or which shall have become
such through an assignment permitted hereby to any person or entity who or which
is an affiliate of the Lender or such holder; provided that, for purposes of
this Note, the term "affiliate" shall have the meaning ascribed thereto in Rule
12b-2 of the General Rules and Regulations of the Securities and Exchange
Commission. This Note shall be construed in accordance with and governed by the
law of The Commonwealth of Virginia.

undated powers and/or endorsements duly executed in blank, all as collateral
security for the payment and performance of the Note. All property at any time

                                                                     /s/ FCH JWM

shall not be liable for failure to collect or realize upon the Note or any
collateral security or guaranty thereof, or any part thereof, or for any delay
in so doing, nor shall Secured Party be under any obligation to take any action
whatsoever with regards thereto. Any or all shares of the Pledged Securities
held by the Secured Party hereunder may, if an Event of Default under the Note
has occurred and is continuing, and upon written notice by the Secured Party to

any time thereafter, without notice, exercise all voting and corporate rights of
any issuer of any and all rights of conversion, exchange, subscription or any
other rights, privileges or options pertaining to any shares of the Pledged
Securities as if the Secured Party were the absolute owner thereof, including,
without limitation, the right to exchange, at its discretion, any and all of the
Pledged Securities upon the merger, consolidation, reorganization,
recapitalization or other readjustment of any issuer of any such shares or upon
the exercise by and such issuer or the Secured Party of any right, privilege or
option pertaining to any shares of the Pledged Securities and, in connection
therewith, to deposit and deliver any and all of the Pledged Securities with any
committee, depository, transfer agent, registrar or other designated agency on
such terms and conditions as the Secured Party may reasonably determine.

                                                                     /s/ FCH JWM
<PAGE>

                  5.2 Secured Party as Attorney-in-Fact. The Secured Party is
                      ---------------------------------
hereby appointed the attorney-in-fact of the Pledgor for the purpose of carrying
out the provisions of this Pledge Agreement and taking any action and executing
any instruments, in the name of the Pledgor or otherwise, that the Secured Party
may reasonably deem necessary or advisable to accomplish the purposes hereof,
which appointment as attorney-in-fact is irrevocable and coupled with an
interest. Without limiting the generality of the foregoing, the Secured Party
shall, to the extent permitted hereunder, have the right and power, upon the
Secured Party's reasonable determination that such action is necessary or
desirable to preserve and protect its interest in the Pledged Collateral, to
receive, endorse and collect all checks and other orders for the payment of
money made payable to the Pledgor representing any dividend, interest payment or
other distribution payable or distributable with respect to the Pledged
Collateral or any part thereof and to give full discharge for the same.

                      --------------------------------
not have any obligation to protect, secure, perfect or insure any Pledged
Collateral at any time held as security for the Note other than to refrain from
acts or omissions constituting gross negligence or willful misconduct with
respect thereto.

SECTION 6. REMEDIES.

         If an Event of Default under the Note has occurred and is continuing,
then, and in any such event, the Secured Party may exercise, in addition to all
other rights and remedies granted to it in this Pledge Agreement and in any
other instrument or agreement securing, evidencing or relating to the Note, all
rights and remedies of a secured party under the Uniform Commercial Code or
other applicable law. Without limiting the generality of the foregoing, the
Pledgor expressly agrees that in any such event, the Secured Party, without
demand of performance or other demand, advertisement or notice of any kind
(except public notice of the time and place of public or private sale, with a
copy thereof to be delivered to the Pledgor) to or on the Pledgor or any other
person (all and each of which demands, advertisements and/or notices, except
such notice of public or private sale, are hereby expressly waived), may
forthwith collect, receive, appropriate and realize on the Pledged Collateral,
or any part thereof, and forthwith sell, assign, give option or options to
purchase, contract to sell or otherwise dispose of and deliver the Pledged
Collateral, or any part thereof, in one or more units, parcels, or lots at one
or more public or private sales, on any stock exchange or through any recognized
securities trading system, at any of the Secured Party's offices or elsewhere,
on such terms and conditions as it may reasonably deem advisable and at such
prices as it may reasonably deem appropriate, for cash or on credit or for
future delivery without assumption of any credit risk; provided that either the
Secured Party or the Pledgor upon any such sale or sales, public or private, may
purchase the whole or any part of the Pledged Collateral so sold. Any purchaser
at any such sale or sales shall acquire the property sold absolutely free from
any claim or right on the part of the Pledgor.

                                                                     /s/ FCH JWM

written request, defend the Secured Party's right, title and first-priority
security interest in and to the Pledged Securities and the proceeds thereof
against the claims and demands of all persons whomsoever;

                  7.2 Limitation on Transfers and Liens. He will not sell,
                      ---------------------------------
assign, transfer, exchange or otherwise dispose of, or grant any option with
respect to any of the Pledged Collateral, nor will he create, incur or permit to
exist any lien with respect to any of the Pledged Collateral (except for the
lien created by this Pledge Agreement) which is not by its express terms junior
in priority to the lien created by this Pledge Agreement; and

SECTION 8. FURTHER ASSURANCES.

         The Pledgor agrees that at anytime and from time to time, on the
written request of the Secured Party, the Pledgor will execute and deliver such
further documents and do such further acts and things as the Secured Party may
reasonably request in order to effectuate the purposes of this Pledge Agreement.

SECTION 9. NOTICES.

         Except as otherwise provided herein, all notices, requests and demands
to or upon a party hereto, to be effective, shall be in writing and shall be
sent by personal delivery, by overnight courier, by certified or registered

SECTION 10. SEVERABILITY.

         Wherever possible, each provision of this Pledge Agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Pledge Agreement shall be prohibited by or invalid
under applicable law, such provision shall be ineffective only to the extent of
such prohibition or invalidity, without invalidating the remainder of such
provision or the remaining provisions of this Pledge Agreement.

SECTION 11. NO WAIVER, CUMULATIVE REMEDIES.

         The Secured Party shall not by any act, delay, omission or otherwise be
deemed to have waived any of its rights or remedies hereunder, and no waiver
shall be valid unless in writing, signed by the Secured Party, and then only to
the extent therein set forth. A waiver of any right or remedy hereunder on any
occasion shall not be construed as a bar to any right or remedy that the Secured
Party would otherwise have on any future occasion. No failure to exercise nor
any delay in exercising, on the part of the Secured Party, any right, power or
privilege hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any right, power or privilege hereunder preclude any other
or further exercise of any right, power or privilege. The rights and remedies
herein provided are cumulative, may be exercised singly or concurrently and are
not exclusive of any rights or remedies provided by law to the Secured Party as
a secured party having a first-priority lien on the Pledged Collateral; provided
that the rights of the Secured Party with respect to the Pledged Collateral
hereunder or as provided by law to such a secured party shall be the Secured
Party's sole recourse for repayment of the loan secured hereby and the Secured
Party hereby acknowledges and agrees that it shall have no personal recourse
against the Pledgor or recourse against any of the Pledgor's property of any
kind or description other than the Pledged Collateral as aforesaid for the
repayment of such loan.

SECTION 12. NO ORAL MODIFICATION, SUCCESSORS, GOVERNING LAW.

         None of the terms or provisions of this Pledge Agreement may be waived,
altered, modified or amended except by an instrument in writing, duly executed
by the Secured Party. This Pledge Agreement and all obligations of the Pledgor
hereunder shall be binding on his successors and assigns and shall, together
with the rights and remedies of the Secured Party hereunder, inure to the
benefit of the Secured Party and its respective successors and assigns. This
Pledge Agreement shall be governed by, and construed and interpreted in
accordance with, the law of The Commonwealth of Virginia.

SECTION 13. TERMINATION.

         This Agreement shall terminate when the Note has been fully satisfied,
at which time the Secured Party shall reassign and deliver to the Pledgor,
against receipt, the Pledged Collateral, or such part thereof as shall not have
been sold or otherwise applied by Secured Party pursuant to

                                                                     /s/ FCH JWM
<PAGE>

the terms hereof, and shall still be held by it hereunder, together with
appropriate instruments of reassignment.

SECTION 14. COUNTERPARTS.

         This Pledge Agreement may be executed in any number of separate
counterparts, and all of said counterparts taken together shall be deemed to
constitute one and the same instrument.

SECTION 15. DESCRIPTIVE HEADINGS.

only and shall not define or limit the provisions hereof.

         IN WITNESS WHEREOF, the Pledgor and the Secured Party have executed and

     committed by ONESOFT,
     (iii) Failure by ONESOFT to comply with governmental laws and regulations;
     (iv) Infringement by ONESOFT of United States patents, United States
     copyrights, United States trademarks, United States trade secrets and other
     United States intellectual property rights.
     (v) This Subparagraph (a) shall not apply to claims arising as a result of
     CLIENT's improper use of ONESOFT's products or services or other
     deliverables under this Agreement.
(b) Indemnification by CLIENT. CLIENT will indemnify, defend and hold harmless
    -------------------------
ONESOFT from all costs (including reasonable attorneys' fees) arising from a
third party claim against ONESOFT based on an actual or alleged:
     (i) Failure by the CLIENT to perform its obligations under this Agreement;
     (ii) Breach of CLIENT's representations and warranties;
     (iii) Acts or omissions constituting negligence or willful misconduct,
     committed by CLIENT; or
     (iv) Failure by CLIENT to comply with governmental laws and regulations; or
     (v) Infringement by CLIENT (or any property or data provided by CLIENT) of
     any patent, copyright, trademark trade secret or other intellectual
     property right.
(c)  Notice of Claim. If a claim covered under this Paragraph 15 appears likely
     ---------------
or is made, the party against whom the claim is made (hereinafter referred to as
the "Indemnitee") will promptly provide the other party (hereinafter referred to
as the "Indemnitor") with notice of such claim. If a claim for infringement is
made, ONESOFT may elect to avoid the infringement by:
     (i) Obtaining the necessary rights for the Indemnitee to continue to use
     the data or software at issue; or
     (ii) Modifying the data or software at issue at its expense; or
     (iii) Terminating this Agreement, and/or Product Addendum(s) and/or
     licenses or Scope(s) of Work and/or Change Orders, and equitably adjusting
     the charges to the extent of such termination(s).

16. INJUNCTIVE RELIEF
The parties acknowledge that monetary damages may not be an adequate remedy if a
party breaches its obligations under Paragraphs 2(b) & (c), 9, 10 or 12, since
such breach will result in irreparable harm.  The parties therefore agree that,
in the event of any such breach, the non-breaching party shall be entitled to
appropriate mandatory or prohibitory injunctive relief against the breaching
party, in addition to any other remedies at law, in equity or under this
Agreement.  A party substantially prevailing in an action for injunctive relief
in connection with this Agreement shall be entitled to recover its costs
(including without limitation reasonable attorneys' fees) from the other party.

17.  TERMINATION
(a) Unless otherwise expressly provided for in this Agreement, either party may
terminate this Agreement or any Scope(s) of Work and/or Change Order(s) and/or
Product Addendum(s), and/or any related licenses granted hereunder or
thereunder, by giving the other party written notice to that effect, effective
on the date of receipt of such notice, if:
     (i) The other party enters into liquidation, whether or not voluntarily, or
     a receiver is appointed to all or any part of its assets, or the other
     party becomes bankrupt or insolvent or enters into any arrangement with its
     creditors, or takes or suffers any similar action in consequence of debt or
     becomes unable to pay its debts as they fall due; or
     (ii) The other party materially breaches this Agreement and fails to cure
     such breach to the non-breaching party's satisfaction within ten (10) days
     of having received written notice of such breach.
(b) ONESOFT may immediately terminate any part of this Agreement if CLIENT
materially breaches any of the provisions of Paragraphs 2(b) & (c), 4, 8, 9, 10,
or 12, of this Agreement.
(c) If a license granted by ONESOFT is terminated for any reason, CLIENT shall,
on the effective date of such termination, cease using any and all of the
subject matter of the license and CLIENT shall promptly deliver to ONESOFT all
copies of any and all of such subject matter and any related documentation, or
shall provide evidence, satisfactory to ONESOFT, that all such copies have been
destroyed.

18. FORCE MAJEURE AND ACTS OF GOD
A party shall be relieved from an obligation while a cause outside the
reasonable control of the party prevents the performance of such obligation.

19. RELATIONSHIP OF THE PARTIES; CONTENT
(a)   Nothing in this Agreement shall be construed as making a party an agent of
the other party, and neither party shall have the power to bind the other party
or to contract in the name of, or create a liability against, the other party.
Neither party shall be responsible for the acts or defaults of the other party
or any of the other party's employees or agents.  The parties are independent
contractors with respect to all matters arising under this Agreement.  Nothing
in this Agreement shall be deemed to establish a partnership, joint venture,
association or employment relationship between the parties.  With respect to its
employees, a party shall remain responsible, and shall indemnify and hold
harmless the other party, for the withholding and payment of all Federal, state
and local personal income, wage, earnings, occupation, social security, worker's
compensation, unemployment, sickness and disability insurance taxes, payroll
levies or employee benefit obligations

(b) If a Scope of Work permits CLIENT to re-sell ONESOFT Services to end-users
then the provisions of this Paragraph 19(b) shall apply to such Services,
however, the CLIENT acknowledges that the Scope of Work still governs the
relationship between ONESOFT and the CLIENT. CLIENT's relationship with any
end-user of the Services that may be distributed by CLIENT shall be governed
solely by an end-user Agreement (made available to ONESOFT upon request) that
provides at least the same protections to ONESOFT as this Agreement and the
Scope of Work provides. Any warranty provided by ONESOFT shall be solely for the
benefit of CLIENT. In no event shall any end-user of CLIENT services be
considered a third party beneficiary of any ONESOFT warranty. CLIENT shall
indemnify and hold ONESOFT harmless from any end- user claim. The CLIENT is
responsible for ensuring that third party end- users of the Services do not
impose unexpected workloads on the Services.
(c) The parties acknowledge that the Internet is neither owned nor controlled by
any one entity and that a third party may gain access to ONESOFT. Electronic
mail and other transmissions passing through ONESOFT or over the Internet are
not secure, and ONESOFT cannot guarantee the security or privacy or any of the
information or communications passing through ONESFOT. ONESOFT agrees to provide
commercially reasonable security consistent with its business practices and
facilities, including (without limitation) access control software,
identification protection, logon passwords and physical site security. In no
event however, will ONESOFT be liable for any loss or damage caused by a breach
of security by a third-party. ONESOFT will not intentionally monitor or disclose
any private electronic communications, except to the extent necessary to
identify or resolve system problems or as otherwise permitted or required by
law. ONESOFT does, however, reserve the right to monitor transmissions, other
than private electronic communications, as necessary to provide the Service and
otherwise to protect the rights and property of ONESOFT. Notwithstanding the
foregoing, ONESOFT does not assume any liability for any action or inaction with
respect to such communication or content posted or provided by an authorized or
unauthorized third party. ONESOFT is a distributor and not a publisher of
CLIENT's data or any other content provided by CLIENT or others (including end
users). Because communication of data and other content over the Internet occurs
in real time, ONESOFT cannot, and does not intend to, screen, police, edit, or
monitor communications and content. If ONESOFT is notified of any content that
allegedly violates its Client Guide, Email Authorized Use Policies, and/or is
otherwise unlawful, ONESOFT may investigate and remove or request the removal of
such content as it deems appropriate in good faith and in its sole discretion.
In no event will ONESOFT be liable for any loss or damage caused by a user's
reliance on any data or other content obtained through ONESOFT

20.  FURTHER ASSURANCES
The parties agree to do all such things and to execute such further documents as
may reasonably be required to give full effect to this Agreement.

21.  WAIVER
No waiver of any part of this Agreement shall be effective unless made in
writing by the waiving party.  No waiver of any breach of this Agreement shall
constitute a waiver of any other breach of the same, or any other provision, of
this Agreement.

22.  ENTIRE AGREEMENT AND CONSTRUCTION
This Agreement constitutes the entire agreement between the parties with respect
to the subject matter hereof and the parties agree that there are no other
representations, warranties or oral agreements relating to the subject matter of
this Agreement.  Headings are included in the Agreement for convenience only and
shall not affect the meaning or construction of this Agreement's provisions.

23.  AMENDMENT
This Agreement may be modified or amended only by means of a writing executed by
both parties.

24.  ASSIGNIBILITY AND RESALE
Rights under this Agreement shall not be assigned, sublicensed, encumbered by
security interest or otherwise transferred or resold by CLIENT (whether by
operation of law or otherwise) without the prior written consent of ONESOFT, and
any purported assignment, sublicense, encumbrance or other transfer of such
rights, in violation of this Agreement, shall be void.  An amalgamation,
acquisition, or merger of CLIENT by or with any person or entity who is not a
party to this Agreement shall be treated as an assignment of this Agreement that
is subject to the provisions of the next preceding sentence.  Notwithstanding
the foregoing, if a Scope of Work so provides, CLIENT may use the Services under
the Scope of Work in support of its internal business operations and may also
distribute such Services to unrelated third parties for their internal use (by
such third party organization's own personnel) and to ultimate end-users in the
public at large, subject to the terms, conditions and limitations of this
Agreement and such Scope of Work, and provided that CLIENT shall defend,
indemnify and hold ONESOFT harmless from all costs (including reasonable
attorneys' fees) arising from any claim by a third party user such Services.  In
connection with any acquisition, merger, consolidation or sale of assets to or
with another entity, ONESOFT may assign this Agreement.

25. COMPLIANCE WITH LAWS
CLIENT shall carry out the obligations contemplated by this Agreement and shall
otherwise deal with the subject matter hereof in compliance with all applicable
laws, rules and regulations, of all governmental authorities, including, without
limitation, the Export Act and any other legal restrictions on exports, and
shall obtain all permits and licenses required in connection with the subject
matter hereof.

26. SUCCESSORS AND ASSIGNS
This Agreement shall inure to the benefit of, and be binding upon the parties,
their successors and permitted assigns.

27. SEVERABILITY
If any provision, of this Agreement or a Product Addendum or Schedule or Scope
of Work or Change Order, is held to be unenforceable, all remaining provisions
thereof shall remain in full force and effect.

28. GENERAL PROVISIONS
(a) CLIENT shall not directly or indirectly solicit or offer employment to, or
directly or indirectly accept services by an employee or contractor of ONESOFT,
during the term of this Agreement and for two (2) years thereafter, without
consent of ONESOFT. For purposes of this Agreement, use of general employment
advertising and independent employment agencies, if not directed at ONESOFT
employees, shall not constitute solicitation.
(b) Each party (i) agrees to inform the other party of any information made
available to such other party that is classified or restricted data, (ii) if
given such information agrees to comply with the security requirements imposed
by any state or local government, or by the United States Government, and (iii)
if given such information agrees

return all copies of such information upon request.
(c) Each party warrants and represents that its participation in this Agreement
does not conflict with any contractual or other obligation of the party or

governmental authority, and shall promptly notify the other party if any such
conflict arises during the term of this Agreement.
(d) Each party shall maintain commercially reasonable and adequate insurance
protection covering its respective activities hereunder, including coverage for
statutory worker's compensation, comprehensive general liability for bodily
injury and tangible property damage, as well as adequate coverage for vehicles.

PRODUCT ADDENDUM #  **********
----------------

THIS PRODUCT ADDENDUM relates to OneSoft Managed Application and Services
Agreement Number: *********** (hereinafter "Agreement") as of June 18, 1999,
Capitalized terms not otherwise defined herein shall have the meanings ascribed
to them in the Agreement.

Each Software Product identified in the Quotation/Estimate in the attached
Schedule(s) A shall, upon execution of this Product Addendum, and subject to the
provisions of this Product Addendum and the Agreement, be deemed a Software
Product for purposes of the Agreement, for the term specified in the attached
Schedule(s), but in any event only for so long as: (a)(i) all related Recurring
Monthly Managed Application, Software Maintenance and Support Services (as
defined below) fees are and have been timely paid by CLIENT with respect to such
Software Product or (ii) the license for the Software Product is a perpetual
license; and (b) each limitation on the number of Processors, Servers, Sites,
Seats, Users and/or other limitations identified in the attached Schedule(s), if
any for each such Software Product, is and has been complied with by CLIENT with
respect to such Software Product. ONESOFT shall in no event have any obligation
to provide Software Maintenance or Support Services with respect to a Software
Product unless the installed Software Product is the then current Release.
Subject to the provisions of the Agreement and this Product Addendum, if a
license identified in Schedule A is designated as "perpetual" then such license
shall continue indefinitely unless terminated pursuant to the Agreement or this
Product Addendum.

Under this Product Addendum, CLIENT is receiving a license only for use with the
unit(s) of measure specified for each Software Product, and only for use on a
Server operated by ONESOFT, CLIENT, or CLIENT's designee inside the continental
United States. The Initial License fees (including the first year of Software
Maintenance and Installation fees), are listed for each Software Product on
Schedule A. For those Software Products that are to be managed on a Server
operated by ONESOFT, the monthly Managed Application and any additional Software
Maintenance and Support Services fees associated with each Software Product are
also listed on Schedule A. As long as all applicable fees are and have been
timely paid by CLIENT for each Software Product listed on Schedule A, ONESOFT
shall supply Software Maintenance and Support Services for the Software
Product(s) pursuant to the Agreement.

If the Software Products are not used on a Server operated by ONESOFT on a
Managed Application basis then Software Maintenance and Support Services fees
for any Renewal Support Year (defined as each yearly period beginning with the
first anniversary of the effective date of this Product Addendum), shall be
billed to the CLIENT at the rate of ***% of then-current ******** license fee
for each Software Product. If fees for Software Maintenance and Support Services
are not timely paid for a Renewal Support Year, Maintenance and Support Services
shall lapse and may only be re-instated if CLIENT pays all unpaid fees for each
Renewal Support Year (whether or not services were received) since the effective
date of this Product Addendum together with an additional fee equal to *******
(***%) percent of such unpaid fees.

For a Software Product licensed on a month-to-month basis, upon completion of
the related Managed Application term, the CLIENT has the option to purchase a
perpetual, non-exclusive object code license of such Software Product for a
discounted fee of ***% of the ********** for each Software Product.

Error Correction and Telephone Support Services Provisions
     ONESOFT shall provide a 24/7 toll free support number monitored by a
ONESOFT employee, to handle all customer inquiries. ONESOFT shall use reasonable
commercial efforts to correct or provide a usable work-around solution for any
reproducible material error in the Software Product(s) within a reasonable
period of time. Additionally, ONESOFT shall use reasonable commercial efforts to
provide technical support for its managed hardware that mechanically
malfunctions. ONESOFT agrees, if feasible, to the following response times when
such an error or malfunction is detected: 1) for Severe situations (those in
which the Customer is unable to conduct its normal Internet business
operations), *****************; 2) for Moderate situations (those in which the
Customer's System is substantially operational but requires a patch, workaround
or bug fix), **************; and 3) for Minor situations (those in which the
error or malfunction is merely an annoyance), **************.
     ONESOFT shall, during the hours of 8:00 a.m. to 8:00 p.m. in ONESOFT's home
office time zone on weekdays (exclusive of

                                       1

holidays), make reasonable knowledge base telephone support available to
CLIENT's Point of Contact identified in the Agreement, a Scope of Work, and/or
this Product Addendum, and other personnel of CLIENT who have been trained in
the use of the Software Product(s). ONESOFT reserves the right to require CLIENT
to reimburse ONESOFT for long distance telephone charges incurred by ONESOFT in
the provision of telephone support and for expenses associated with determining
if technical support was reasonably required by CLIENT.
     If ONESOFT, in its discretion, requests written verification of an error or
malfunction discovered by CLIENT, CLIENT shall promptly provide such
verification, by email, facsimile, or overnight mail, setting forth in
reasonable detail the respects in which the Software Product(s) fail to perform.
An error or malfunction shall be "material" if it represents a nonconformity
with ONESOFT's current published specifications for the Software Product(s) that
interferes with the usability of the Software Product(s). ONESOFT is not
obligated to fix errors that are not material. If applicable to a perpetual
license, and upon request, CLIENT shall provide ONESOFT remote access to
CLIENT's Server for the purpose of remote diagnostics.
     If applicable to a perpetual license, CLIENT will install the equipment and
software as required by ONESOFT to permit any of the Software Maintenance and
Support Services to be delivered electronically.
     CLIENT shall pay ONESOFT at ONESOFT'S then current time and material rates
for work of ONESOFT spent investigating an error or malfunction that ONESOFT
reasonably determines to have been caused by a modification to the Software
Product(s) not made nor authorized in writing by ONESOFT.

IN WITNESS WHEREOF, the parties have executed this Product Addendum effective as
of the date first written above.
