     This Agreement is made and entered into as of the 18th day of August, 2000,
by and among S2 Systems, Inc., a Delaware corporation (the "COMPANY"), those
individuals and entities listed on SCHEDULE 2.1 attached hereto ("PURCHASERS")
and, for the limited purposes set forth in SECTION 5 and SECTION 6 hereof, Tula
Holdings, LLC ("TULA"). Certain capitalized terms used in this Agreement are
defined in SECTION 12.1.

     In consideration of the mutual promises, covenants and conditions
hereinafter set forth, the parties hereby agree as follows:

SECTION 1. AUTHORIZATION OF CAPITAL STOCK.

     The Board of Directors of the Company (the "BOARD") has authorized the
filing of the Second Restated Certificate of Incorporation which includes, among
other things, the preferences and rights of the Series B Convertible Preferred
Stock (the "CERTIFICATE") in the form of EXHIBIT A attached hereto, creating a
new series of preferred stock consisting of 1,960,000 shares of Series B
Convertible Preferred Stock, par value $.01 per share (the "SERIES B PREFERRED
STOCK"). The terms, limitations and relative rights and preferences of the
Series B Preferred Stock are set forth in the Certificate.

SECTION 2. PURCHASE AND SALE OF STOCK.

     2.1. PURCHASERS OF SERIES B PREFERRED STOCK. Subject to the terms and
conditions set forth in this Agreement and in reliance upon the representations
set forth below, on the Closing Date (as defined below) the Company will sell to
Purchasers, and Purchasers will purchase from the Company at a purchase price
equal to $6.00 per share, 1,000,000 shares of Series B Preferred Stock for an
aggregate purchase price of $6,000,000. Such sale and purchase shall be effected
on the Closing Date by the Company executing and delivering to Purchasers, duly
registered in Purchasers' name, duly executed stock certificates evidencing the
Series B Preferred Stock to be purchased under this Agreement, against delivery
at Closing by Purchasers to the Company of an aggregate of $6,000,000 payable by
Purchasers. Each Purchaser will purchase the number of shares of Series B
Preferred Stock set forth on SCHEDULE 2.1 beside such Purchaser's name. At
Closing, each Purchaser will pay the amount set forth on SCHEDULE 2.1 beside
such Purchaser's name by transfer of such amount to the account of the Company
by wire transfer of immediately available funds. As soon as practicable
following Closing, the Company will deliver to each Purchaser a certificate
registered in the Purchaser's name evidencing the number of shares of Series B
Preferred Stock set forth opposite the Purchaser's name on SCHEDULE 2.1 dated as
of the Closing Date.

     2.2. CLOSING. The closing of the sale and purchase referred to in Section
2.1 (the "CLOSING") shall take place at 10:00 A.M., Central Standard time, on
August 18, 2000 or such other date as Purchasers and the Company may mutually
agree in writing (the "CLOSING DATE"), at the offices of S2 Systems, Inc., 4695
Preston Park Boulevard, 8th Floor, Plano, Texas 75093 or such other location as
Purchasers and the Company shall mutually select.

     2.3. ADDITIONAL CLOSINGS. The Purchasers hereby acknowledge and agree that
the Company may issue up to an additional 960,000 shares of Series B Preferred
Stock at a per share purchase price of not less than $6.00 to other purchasers
not a party to this Agreement, provided that the closing of the transactions
contemplated by the agreement for sale occurs not later than 15 business days
after the Closing Date. Any such purchaser shall become a party to this
Agreement. The Company confirms to each Purchaser that the Company will not
grant any purchaser of such additional shares of Series B Preferred Stock rights
which are greater than or in any respect different from the rights granted to
the Purchasers under this Agreement or the Certificate. As soon as practicable
after 15 business days after the Closing Date, the Company agrees to take all
reasonable action necessary to amend its certificate of incorporation to provide
that the Company is authorized to issue only such number of shares of Series B
Preferred Stock as have been purchased pursuant to this Agreement. The
Purchasers hereby waive any preemptive rights they may have with respect to any
issuance of Series B Preferred Stock in accordance with this SECTION 2.3.

SECTION 3. AMENDMENT TO SERIES B RIGHTS.

     3.1. AUTOMATIC AMENDMENT. Until March 31, 2001, if the Company issues
equity securities pursuant to a subsequent round of preferred stock financing
(the "SUBSEQUENT ROUND") with rights or preferences equal or superior to the
rights or preferences of the Series B Preferred Stock, determined as set forth
below, all of the

                                       1

<PAGE>

rights under the Series B Preferred Stock shall, subject to the limitations
set forth below, be amended to conform to the rights granted to the securities
issued in the Subsequent Round (the "RIGHTS AMENDMENT"). Notwithstanding the
preceding sentence, the Rights Amendment will not automatically occur unless
holders of a majority of the Series B Preferred Stock determine, in their
reasonable judgment that (i) at a minimum, each of the conversion, anti-dilution
and liquidation rights and preferences of the Subsequent Round, measured
independently of each other and all other rights, are equal or superior to each
of such comparable rights of the Series B Preferred Stock, and (ii) all other
material rights, including without limitation, dividend, registration, co-sale,
drag along, first refusal and the restrictive covenants, are, when viewed as a
whole, equal or superior to the rights of the Series B Preferred Stock. When
making the determination of whether the rights and preferences of the securities
issued in the Subsequent Round are equal or superior, the holders of the Series
B Preferred Stock shall not consider or compare the redemption rights and
preferences of the Series B Preferred Stock to those of the securities issued in
the Subsequent Round.

     3.2. VOLUNTARY AMENDMENT. If the rights of the securities issued in the
Subsequent Round are not equal or superior to the Series B Preferred Stock, as
determined pursuant to the provisions of Section 3.1, the holders of a majority
of the Series B Preferred Stock may nevertheless elect to effect the Rights
Amendment in the same way as contemplated by the automatic amendment provisions
above.

     3.3. DIVIDENDS. Subsequent to the effectiveness of the Rights Amendment,
dividends, if any, applicable to the securities issued in the Subsequent Round
shall be converted into a percentage amount and be applied to the Series B
Preferred Stock commencing with the effective date of the filing of the
certificate of incorporation relating to the Subsequent Round.

     3.4. AMENDMENT PROCEDURE.

     (a) Until the earlier to occur of March 31, 2001 or the closing of the
Subsequent Round, if the Company makes an offering of a Subsequent Round, it
shall notify the holders of the Series B Preferred Stock of the commencement of
such offering and shall promptly provide the holders of the Series B Preferred
Stock with the offering memorandum (if any) and other offering documents
utilized for such offering. The Company shall notify the holders of the Series B
Preferred Stock of the anticipated closing date of the Subsequent Round and give
such holders at least 15 days written notice prior to the closing date of the
Subsequent Round. At least 5 days prior to the closing date of the Subsequent
Round the holders of a majority of the Series B Preferred Stock shall deliver
written notice to the Company that, in their reasonable judgment, either (i) the
rights of the securities to be issued in the Subsequent Round are equal or
superior to those of the Series B Preferred Stock, or (ii) such rights are
inferior. If the holders determine such rights are inferior, such holders shall
deliver to the Company with such written notice a list all of the rights the
holders deem to be inferior and provide a written explanation, in reasonable
detail, setting forth the rationale for determining that such rights are
inferior.

     (b) If the rights of the securities to be issued in the Subsequent Round
are determined by a majority of the holders of the Series B Preferred Stock to
be equal or superior, or if determined to be inferior but a majority of the
holders of the Series B Preferred Stock elect to amend the rights of the Series
B Preferred Stock under the voluntary amendment provisions set forth above, then
all of the rights of the Series B Preferred Stock will be amended and evidenced
in appropriate certificates, agreements, instruments or other documents so as to
become as identical to the rights of the securities issued in the Subsequent
Round as is practicable. The Rights Amendment will become effective upon the
effectiveness of the certificate of incorporation respecting the securities
issued in the Subsequent Round filed with the Secretary of State of the state of
Delaware.

     (c) If the rights of the securities to be issued in the Subsequent Round
are determined by a majority of the holders of the Series B Preferred Stock to
be inferior to the rights of the Series B Preferred Stock and such holders
notify the Company that they do not elect to invoke the voluntary amendment
provisions set forth above, then the rights of the Series B Preferred Stock will
remain in full force and effect and shall be set forth in full without amendment
in the Certificate. Notwithstanding the preceding sentence, if the Company
disagrees with the determination by the majority of the Series B Preferred Stock
regarding the inferiority of the rights of the securities to be issued in the
Subsequent Round, then the Company and a majority of the holders of the Series B
Preferred Stock shall select a mutually agreeable third party to make an
independent determination, at the Company's expense, as to whether the rights of
the securities to be issued in the Subsequent Round are equal or superior to
those of the Series B Preferred Stock. The independent third party shall use the
criteria set forth in SECTION 3.1 to make its determination. The determination
of the third party shall be binding upon the parties hereto and, if such third
party determines that the rights of the securities to be issued in the
Subsequent Round are equal or superior, then the Rights Amendment shall be
effectuated and the rights of the Series B Preferred

                                       2
<PAGE>

Stock shall be amended as set forth above. If such third party determines
that the rights are inferior, then the rights of the Series B Preferred Stock
shall remain unchanged.

     3.5. FURTHER ACTIONS. The parties hereto agree to take all actions and
execute all documents that may be necessary or desirable to consummate the
Rights Amendment.

SECTION 4. VOTING.

    4.1. VOTING AS A GROUP. Subsequent to the effectiveness of the Rights
Amendment, if any item is put to a vote which may or is required to be made
separately by each series or class of equity securities, to the extent permitted
by applicable law, the Series B Preferred Stock shall vote with and be
considered a part of the series or class of securities issued in the Subsequent
Round. The voting of shares pursuant to this Agreement may be effected in
person, by proxy, by written consent, or in any other manner permitted by
applicable law, the Company's certificate of incorporation and the Company's
bylaws.

     4.2. VOTING AS A SERIES.

     (a) If, subsequent to the effectiveness of the Rights Amendment, the
holders of the Series B Preferred Stock are required by law to vote on any
matter as a separate class or series of securities, such holders agree that the
Company shall exercise the proxies granted the Company in SECTION 4.2(b) below
to vote the shares of Series B Preferred Stock in favor of the item put to a
vote in the same ratio as the holders of the series or class of securities
issued in the Subsequent Round, as adjusted and determined as follows:

        (i) for purposes of determining the total number of votes to be used in
the denominator, the number of votes represented by the voting rights of the
Series B Preferred Stock shall be added to the number of votes represented by
the voting rights of the series or class of securities issued in the Subsequent
Round, which votes were actually cast in the vote taken by the holders of the
securities issued in the Subsequent Round;

        (ii) the numerator shall equal the number of votes actually cast by the
holders of the securities issued in the Subsequent Round in favor of the item
plus the number of votes represented by the voting rights of the Series B
Preferred Stock that the holders of the Series B Preferred Stock have determined
to vote in favor of the item; and

        (iii) the numerator determined pursuant to subsection (ii) above shall
be divided by the denominator determined pursuant to subsection (i) above to
determine the ratio in which the shares of Series B Preferred Stock must be
voted in favor of the item submitted to a vote of the holders of the Series B
Preferred Stock.

     (b) The Purchasers and any Permitted Transferees hereby constitute and
appoint the Company as the Purchasers' and any Permitted Transferees' true and
lawful proxy, agent, and attorney-in-fact, with full power of substitution to
vote the shares of Series B Preferred Stock, solely in the event that the
holders of the Series B Preferred Stock are required by law to vote on any
matter as a separate class or series of securities subsequent to the
effectiveness of the Rights Amendment, pursuant to the provisions contained in
this SECTION 4. The Purchasers and any Permitted Transferees acknowledge that
such proxies shall be deemed coupled with an interest and are irrevocable for so
long as any shares of the Series B Preferred Stock remain outstanding. Except as
set forth in this SECTION 4, no proxy shall be deemed to be given by the holders
of the Series B Preferred Stock by virtue of this Agreement.

    4.3. LEGEND. Concurrently with the execution of this Agreement, there shall
be imprinted or otherwise placed on certificates representing the shares of the
Series B Preferred Stock the restrictive legend (the "LEGEND") set forth in
SECTION 11.3(c) of this Agreement. The Company agrees that during the term of
this Agreement (i) it will not remove the Legend, and will not permit such
Legend to be removed (upon registration of transfer, reissuance or otherwise),
from any such certificate and (ii) it will place the Legend on any new
certificate issued to represent the shares of Series B Preferred Stock
theretofore represented by a certificate carrying the Legend.

     4.4. BINDING ON SUCCESSORS. The provisions of this SECTION 4 shall be
binding upon the successors in interest to any of the shares of Series B
Preferred Stock. The Company shall not permit the transfer of any of the shares
of Series B Preferred Stock on its books or issue a new certificate representing
any of the shares of Series B Preferred Stock unless and until the person to
whom such security is to be transferred shall have executed a written agreement
pursuant to which such person becomes a party to this Agreement and agrees to be
bound by all the provisions hereof as if such person were a Purchaser.

                                       3

     4.5. SPECIFIC PERFORMANCE. The parties hereto hereby declare that it is
impossible to measure in money the damages which will accrue to a party hereto
or to their heirs, personal representatives, or assigns by reason of a failure
to perform any of the obligations under this SECTION 4 of the Agreement and
agree that the terms of this SECTION 4 of the Agreement shall be specifically
enforceable. If a party hereto or their heirs, personal representatives, or
assigns institutes any action or proceeding to specifically enforce the
provisions hereof, any person against whom such action or proceeding is brought
hereby waives the claim or defense therein that such party or such personal
representative has an adequate remedy at law, and such person shall not offer in
any such action or proceeding the claim or defense that such remedy at law
exists.

SECTION 5. REGISTRATION RIGHTS.

     If and to the extent the holders of shares of Series A Preferred Stock of
the Company receive registration rights with respect to their shares of Common
Stock of the Company, the holders of the Series B Preferred Stock shall be
granted piggyback registration rights with respect to the shares of Common Stock
of the Company into which the Series B Preferred Stock is convertible if the
Corporation registers for sale under the Act, some or all of the shares of its
Common Stock held by the holders of the Series A Preferred Stock pursuant to the
registration rights granted the holders of the shares of Series A Preferred
Stock. The amount of shares of Common Stock which may be registered on behalf of
the holders of Series B Preferred Stock relative to the total amount of shares
of Common Stock determined on a fully converted basis held by such holders shall
be in the same proportion as the amount of shares of Common Stock determined on
a fully converted basis registered on behalf of the holders of Series A
Preferred Stock bears to the total amount of Common Stock determined on a fully
converted basis held by the holders of the Series A Preferred Stock. Any
underwriter cutback shall be applied to maintain the proportion set forth in the
previous sentence.

SECTION 6. TRANSFER RESTRICTIONS.

     6.1. GENERAL PROHIBITION ON TRANSFERS; PERMITTED TRANSFERS.

        (a) Except as otherwise permitted hereby, each Purchaser shall not
directly or indirectly sell, assign, pledge or encumber or otherwise
transfer to any person (a "TRANSFEREE") any shares of Series B Preferred Stock
(or any shares of Common Stock received on conversion of the shares of Series B
Preferred Stock) (the "STOCK") unless such Purchaser has complied with all of
the terms of this Agreement. Any purported sale, assignment, pledge, encumbrance
or other transfer in violation of any provision of this Agreement shall be null
and void and shall not operate to transfer any interest or title to the
purported Transferee.

        (b) The restrictions contained in this Agreement with respect to
transfers by each Purchaser of shares of Stock shall not apply to: (i) a
transfer to an Affiliate of the Purchaser; and (ii) any transfer of Stock by the
Purchaser (A) pursuant to a merger or consolidation of the Purchaser with or
into another corporation or corporations, (B) pursuant to the winding up and
dissolution of the Purchaser, or (C) in, and pursuant to, the Initial Public
Offering (as defined in the Certificate); provided, however, that in clause (i),
each transferee shall, as a condition precedent to such transfer, agree in
writing to be bound by the provisions of this Agreement, and shall have all of
the rights and obligations of the Purchaser hereunder; provided, further, that
in each of the cases of (A) and (B) of clause (ii) hereon, the Purchaser's
shareholders of record as constituted immediately prior to such event will,
immediately after such event, hold less than a majority of the voting power of
the surviving or acquiring entity.

        (c) Under no circumstances will any Purchaser be permitted to sell
shares of Stock to any competitor of the Company or to any entity that owns
in excess of 5% of the equity of a competitor of the Company.

     6.2. RIGHT OF FIRST REFUSAL.

     (a) Except as otherwise permitted in SECTION 6.1(b), transfers of share of
Stock by each Purchaser shall not be permitted unless a Purchaser has complied
with this SECTION 6.2. If the Purchaser (the "PROPOSED SELLER") intends to sell
any of its shares of Stock pursuant to a bona-fide offer from an unaffiliated
third party (the "PROPOSED TRANSFEREE"), it shall give written notice (the
"SELLER'S NOTICE") to the Company and each of the holders of shares of Series A
Preferred Stock (collectively, the "HOLDERS") stating that the Proposed Seller
intends to make such a sale or transfer, identifying the Proposed Transferee,
specifying the number of shares of Stock proposed to be purchased or acquired
pursuant to the offer (the "FIRST REFUSAL SHARES"), and specifying the per share
purchase price that the Proposed Transferee has offered to pay for the First
Refusal Shares (the "SALE PRICE"). Such Seller's Notice shall constitute an
irrevocable offer to sell such First Refusal Shares. A

                                       4
<PAGE>

copy of the offer, if available, and a statement of the number of shares
held by each of the Holders shall be attached to the Seller's Notice.

        (1) Upon receipt of the Seller's Notice, the Company shall have the
exclusive option to purchase, upon delivery to the Proposed Seller within ten
days of its receipt of the Seller's Notice, all or any portion of the First
Refusal Shares. The Company shall deliver a notice (the "COMPANY NOTICE") to the
Proposed Seller and each of the Holders of its election to purchase or not to
purchase such First Refusal Shares within such ten-day period, together with
payment to the Proposed Seller of the Sale Price for such First Refusal Shares.
If the Company fails to deliver the Company Notice within such ten-day period,
the Company will be deemed to have elected not to purchase such First Refusal
Shares. To the extent that the Company does not elect to purchase all of the
First Refusal Shares, the Holders shall have the irrevocable and exclusive
option to purchase all, but not less than all, of the remaining First Refusal
Shares at the Sale Price. Each Holder, upon delivery to the Proposed Seller
within twenty days of its receipt of the Company's Notice, shall have the option
to purchase up to that number of the remaining First Refusal Shares equal to the
product of (A) the number of remaining First Refusal Shares multiplied by (B) a
fraction, the numerator of which shall be the number of shares of Common Stock
owned by such Holder (assuming full conversion and exercise of all convertible
and exercisable securities into Common Stock) and the denominator of which shall
be the number of shares of Common Stock owned by all of the Holders (assuming
full conversion and exercise of all convertible and exercisable securities into
Common Stock) (the "PROPORTIONATE SHARE"). Each Holder shall deliver to the
Proposed Seller a written notice within such twenty-day period stating whether
it elects to exercise its option under this SECTION 6.2(b) and the maximum
number of shares (up to all of such Holder's Proportionate Share) that it is
willing to purchase. Such notice shall constitute an irrevocable commitment to
purchase such shares. If the Holders do not purchase all of the remaining First
Refusal Shares, the Company shall have no right to purchase less than all of the
First Refusal Shares.

        (2) If a Holder does not elect to purchase its full Proportionate Share,
the Proposed Seller shall deliver another written notice to each Holder that has
elected to purchase its full Proportionate Share (a "FULLY EXERCISING HOLDER")
stating the number of unpurchased shares. Each Fully Exercising Holder shall be
entitled, by delivering written notice to the Proposed Seller within five days
following the delivery of such notice, to purchase up to all of the remaining
shares at the Sale Price. In the event of an oversubscription, the
oversubscribed amount shall be allocated among such Fully Exercising Holders
pro-rata based on the number of shares of Common Stock owned by each of them
(assuming full conversion and exercise of all convertible and exercisable
securities into Common Stock). The delivery of the notice of election under this
paragraph shall constitute an irrevocable commitment to purchase such shares.

        (3) Each Holder shall be entitled to assign its rights under this
SECTION 6.2 to any of its Affiliates.

        (4) If all of the First Refusal Shares are not elected to be purchased
pursuant to this SECTION 6.2, then, the Proposed Seller shall be free, for a
period of 90 days from the date of the Seller's Notice, to sell the First
Refusal Shares to the Proposed Transferee, at a price equal to or greater than
the Sale Price and upon terms no more favorable to the Proposed Transferee than
those specified in the Seller's Notice. Any transfer of the remaining First
Refusal Shares by the Proposed Seller after the end of such 90-day period or any
change in the terms of the sale set forth in the Seller's Notice that are more
favorable to the Proposed Transferee shall require the delivery of a new notice
of intent to transfer to the Company and each of the Holders and shall give rise
anew to the rights provided in the preceding paragraphs of ARTICLE 6.

     (b) If the Company or the Holders elect to purchase all of the First
Refusal Shares mentioned in the Seller's Notice, the Company or such Holder
shall have the right to purchase the First Refusal Shares for cash consideration
whether or not part or all of the consideration specified in the Seller's Notice
is other than cash. If part or all of the consideration to be paid for the First
Refusal Shares as stated in the Seller's Notice is other than cash, the price
stated in such Seller's Notice shall be deemed to be the sum of the cash
consideration, if any, specified in such Seller's Notice, plus the fair market
value of the non-cash consideration. The fair market value of the non-cash
consideration shall be determined by agreement of the Company and the Proposed
Seller. If such persons are unable to agree on a fair market value, the Company
and the Proposed Seller shall select a mutually agreeable third party to make an
independent determination, and its judgment as to the fair market value of such
non-cash consideration shall be binding upon the Proposed Seller, the Company
and the Holders.

                                       5

     6.3. DRAG-ALONG RIGHTS.

     (a) At any time after the Closing Date, the parties agree that in the event
holders of at least 50% of the Company's outstanding shares of capital stock
determined on a fully converted basis (the "DESIGNATED HOLDERS") shall at any
time propose to sell a minimum of 50% of the shares of capital stock in the
Company determined on a fully converted basis (collectively, the "EQUITY
SECURITIES"), owned by such Designated Holders, whether by sale, merger,
consolidation or otherwise, to an unaffiliated third party or group of
unaffiliated third parties for cash, cash equivalents or marketable securities
in a privately negotiated transaction, then the Designated Holders shall have
the right to require all of the Purchasers to participate in such transfer, and
such Purchasers shall be obligated to participate in the transfer with respect
to all of their capital stock in the Company, at the same consideration per
share, based upon the number of shares of Common Stock into which each series of
Preferred Stock may be converted, and on the same terms and conditions as the
Designated Holders.

     (b) If the Designated Holders elect to exercise their drag-along rights
under this Section 6.3, they shall do so by delivering a written notice of such
proposed transfer (a "DRAG-ALONG NOTICE") to each Purchaser no later than 30
days prior to the proposed closing thereof. Such notice shall make reference to
the obligations of the Purchasers hereunder and shall describe in reasonable
detail (i) the Equity Securities to be transferred by the Designated Holders,
(ii) the percentage ownership of Equity Securities then outstanding owned by the
Designated Holders, (iii) the person to whom such Equity Securities are proposed
to be transferred, (iv) the terms and conditions of the transfer, including the
consideration to be paid therefor and (v) the proposed date and location of the
closing of the transfer.

     (c) Each Purchaser participating in the transfer shall execute and deliver
such agreement, instruments and certificates as may be reasonably requested by
the proposed purchaser. At the closing of the transfer described in the
Drag-Along Notice, and pursuant to the terms and conditions thereof, each
Purchaser shall thereupon deliver at such closing the certificate or
certificates representing all of the Equity Securities held by it, duly endorsed
for transfer, and shall receive the net proceeds (after deduction of transfer
taxes and fees and other expenses directly attributable to the sale of such
Equity Securities by the Purchasers) allocable to the transfer thereof.

     6.4. TAG-ALONG RIGHTS.

     (a) At any time after the Closing Date, the parties agree that in the event
Designated Holders shall at any time propose to sell a minimum of 50% of the
Equity Securities, owned by such Designated Holders, whether by sale, merger,
consolidation or otherwise, to an unaffiliated third party or group of
unaffiliated third parties for cash, cash equivalents or marketable securities
in a privately negotiated transaction, then the Purchasers shall have the right
to participate in such transfer with respect to all of their capital stock in
the Company, at the same consideration per share, based upon the number of
shares of Common Stock into which each series of Preferred Stock may be
converted, and on the same terms and conditions as the Designated Holders. If
the Designated Holders elect to sell a minimum of 50% of their Equity
Securities, they shall deliver a written notice of such proposed transfer (a
"TAG-ALONG NOTICE") to each Purchaser no later than 30 days prior to the
proposed closing thereof. Such notice shall make reference to the rights of the
Purchasers hereunder and shall describe in reasonable detail (i) the Equity
Securities to be transferred by the Designated Holders, (ii) the percentage
ownership of Equity Securities then outstanding owned by the Designated Holders,
(iii) the person to whom such Equity Securities are proposed to be transferred,
(iv) the terms and conditions of the transfer, including the consideration to be
paid therefor and (v) the proposed date and location of the closing of the
transfer.

     (b) If the Purchasers elect to exercise their tag-along rights under this
Section 6.4, they shall do so by delivering a written notice of such election (a
"TAG-ALONG EXERCISE NOTICE") to each Designated Holder no later than 15 days
prior to the proposed closing thereof. Such notice shall make reference to the
rights of the Purchasers hereunder and shall describe in reasonable detail (i)
the Equity Securities to be transferred by the Purchasers and (ii) the
percentage ownership of Equity Securities then outstanding owned by the
Purchasers. To the extent one or more of the Purchasers exercises such right of
participation in accordance with the terms and conditions set forth in this
Section 6.4, the number of shares of Stock that the Designated Holders may sell
to the proposed transferee shall be correspondingly reduced. Each of the
Purchasers may elect to sell all or any part of that number of shares of Stock
of the Company held by such Purchaser equal to the product obtained by
multiplying (i) the aggregate number of shares to be sold in the proposed sale
by (ii) a fraction the numerator of which is the number of shares of Common
Stock at the time owned by such Purchaser (assuming full conversion and exercise
of all convertible and exercisable securities into Common Stock) and the
denominator of which is

                                       6
<PAGE>

the combined number of shares of Common Stock at the time owned by the
Designated Holders and all of the Purchasers electing to sell hereunder
(assuming full conversion and exercise of all convertible and exercisable
securities into Common Stock). If a Purchaser does not elect to exercise its
tag-along rights under this Section 6.4, the other Purchasers exercising their
tag-along rights shall be entitled to sell, in addition to the number of shares
determined above, the number of shares of Stock as the non-exercising Purchasers
could have sold on the exercise of their tag-along rights, apportioned among the
exercising Purchasers pro rata according to the number of shares of Common Stock
at the time owned by such exercising Purchaser (assuming full conversion and
exercise of all convertible and exercisable securities into Common Stock).

     (c) Each Purchaser participating in the transfer shall execute and deliver
such agreement, instruments and certificates as may be reasonably requested by
the proposed purchaser. At the closing of the transfer described in the
Tag-Along Notice, and pursuant to the terms and conditions thereof, each
Purchaser shall thereupon deliver at such closing the certificate or
certificates representing all of the Equity Securities held by it, duly endorsed
for transfer, and shall receive the net proceeds (after deduction of transfer
taxes and fees and other expenses directly attributable to the sale of such
Equity Securities by the Purchasers) allocable to the transfer thereof.

     6.5. LEGEND ON THE SHAREHOLDERS' STOCK. Each certificate representing
shares of Series B Preferred Stock now or hereafter owned by each Purchaser or
its permitted Transferees pursuant to clauses (i) through (ii) of Section 6.1(b)
shall be endorsed with the restrictive legend set forth in Section 11.3(b).

<PAGE>

     7.7. QUALIFICATION TO DO BUSINESS. The Company is qualified, licensed and
authorized to do business as a foreign corporation in each jurisdiction in which
it owns or leases any material property or in which the conduct of its business
requires it to so qualify or be so licensed, and such jurisdictions constitute
the only jurisdictions in which the conduct of the Company's business or the
nature of the property owned or leased by it require it to qualify to do
business as a foreign corporation, except where the failure to so qualify would
not have a Material Adverse Effect.

     7.8. ABSENCE OF DEFAULTS, CONFLICTS, ETC. The execution and delivery of
this Agreement, the authorization, issuance, offer and sale of the Series B
Preferred Stock contemplated by this Agreement, the adoption by the Company
of the Certificate and the fulfillment of the terms of such documents by the
Company does not (A) result in a breach of any of the terms, conditions or
provisions of, or constitute a default under, or permit the acceleration of
rights under or termination of, any material indenture, mortgage, deed of
trust, credit agreement, note or other evidence of indebtedness, instrument
or other agreement of the Company, or (B) violate the Present Certificate or
Bylaws of the Company, or any rule, regulation, writ, injunction, judgment,
decree, award or other action of any court or Federal or state or other
regulatory board or body or administrative agency having jurisdiction over
the Company or over its properties or businesses. No event has occurred and
no condition exists which, upon notice or the passage of time, or both, would
constitute a default under any such agreements and instruments or in any such
license, permit, rule, regulation, order or authorization to which the
Company is a party or by which it may be bound.

     7.9. DISCLOSURE MATERIALS, FINANCIAL STATEMENTS, MATERIAL LIABILITIES.

     (a) The Company has previously delivered to Purchasers certain materials
containing audited financial statements of the Company for the fiscal year ended
March 31, 2000 and unaudited financial statements for the quarter ended June 30,
2000 (the "FINANCIAL STATEMENTS"). Such Financial Statements, including the
notes thereto (if any), have been prepared from the books and records of the
Company, are true and correct and present fairly the financial position and the
results of operations and cash flows of the Company as at and for the periods
indicated, in each case, except that the unaudited financial statements do not
contain footnotes, in conformity with generally accepted accounting principles
("GAAP") consistently applied. The portions of the materials containing
financial projections and other forward-looking statements were prepared by the
Company in good faith based upon assumptions which the Company believes to be
reasonable in light of facts known to the Company.

     (b) Except as set forth in the Financial Statements, the Company has no
material liabilities or obligations, absolute or contingent, except (i)
obligations and liabilities incurred in the ordinary course of business since
the respective dates of such statements, or (ii) obligations which are not
required by GAAP to be reflected in the Financial Statements or such interim
statements.

     7.10. SECURITY INTERESTS. SCHEDULE 7.10 hereto sets forth (i) any material
lien, charge, security interest or encumbrance with respect to any of the
Company's indebtedness and (ii) a brief description of each instrument or
agreement governing such indebtedness. The Company has provided the Purchaser
with a complete and correct copy of each such instrument or agreement (including
all amendments, supplements or modifications thereto). No default exists with
respect to or under any such indebtedness or any instrument or agreement
relating thereto which default would reasonably be expected to have a material
adverse effect on the Company.

     7.11. ABSENCE OF CERTAIN DEVELOPMENTS. Other than as set forth on SCHEDULE
7.11, since June 30, 2000, there has been no (i) material adverse change in the
condition, financial or otherwise, of the Company or in its assets, liabilities,
properties or business, taken as a whole, (ii) declaration, setting aside or
payment of any dividend or other distribution with respect to the capital stock
of the Company or redemption of any share of capital stock of the Company, (iii)
material loss, destruction or damage to any property of the Company, whether or
not insured, (iv) acceleration or prepayment of any indebtedness for a material
amount of borrowed money or the refunding of any such indebtedness, (v) labor
trouble involving the Company or any material change in its personnel or the
terms and conditions of employment, (vi) waiver of any valuable right which
could reasonably be expected to have a material adverse effect on the business
or financial position of the Company, (vii) material loan or extension of credit
by the Company to any officer or employee of the Company (other than reasonable
travel advances) or (viii) acquisition or disposition of any material assets (or
any contract or arrangement therefor) otherwise than for fair value in the
ordinary course of business, or any other transaction by the Company otherwise
than for fair value in the ordinary course of business.

                                       9
<PAGE>

     7.12. CONTRACTS, AGREEMENTS. All material contracts, agreements and
understandings are in full force and effect and neither the Company nor any
other party thereto has received any notice of default or is in default, and no
condition now exists which, with notice or the lapse of time or both, would
render the Company or, to the knowledge of the Company, any other party, in
default under any material contracts, understandings or agreements to which the
Company is or may be a party. There are no disputes or proceedings relating to
any such material contract, understanding or agreement and the Company has not
received any notice or indication that any party to any such material contract,
understanding or agreement intends to cancel or terminate such contract,
understanding or agreement or intends to exercise or not exercise any options
under such material contract, understanding or agreement.

    7.13. COMPLIANCE WITH LAW. The Company has not been notified of any material
violation of any laws, ordinances, governmental rules or regulations to which it
is subject, including without limitation laws or regulations relating to the
environment or to occupational health and safety, and to its knowledge no
material expenditures are or will be required in order to cause its current
operations or properties to comply with any such law, ordinances, governmental
rules or regulations.

     7.14. PENDING ACTIONS. There is no action, suit, investigation or
proceeding pending or, to the knowledge of the Company threatened, against the
Company or any of its properties or assets by or before any court, arbitrator or
governmental authority which questions the validity of the Present Certificate,
the Agreement or the Certificate, or any action taken or to be taken pursuant
hereto or thereto, or which could reasonably be expected to have a Material
Adverse Effect, and the Company is not in default with respect to any judgment,
order, writ, injunction, decree or award applicable to it or its business or
properties.

     7.15. TAX MATTERS. The Company has completed and duly filed all Federal,
state, county and local tax returns required to have been filed by it and all
taxes which are shown on such returns have been paid (other than taxes contested
in good faith by appropriate proceeding). There are in effect no waivers of
applicable statutes of limitations with respect to taxes for any year. No tax
returns have been audited by taxing authorities.

     7.16. EMPLOYEES. Other than as set forth on SCHEDULE 7.16, the Company does
not have any employment contract with any of its employees (other than severance
or employment agreements terminable by the Company without premium or penalty on
notice of 30 days or less), or any collective bargaining agreements covering any
of its employees, nor has the Company been subject to any labor organization
activity. There are no material controversies or labor troubles pending or, to
the knowledge of the Company threatened, between the Company and any of its
employees. The Company has complied in all material respects with all applicable
federal and state laws and regulations respecting employment and employment
practices, terms and conditions of employment, wages and hours and other laws
related to employment. No key employee or consultant of the Company has within
the prior three months given any written notice to the Company that he or she
intends to leave the employ of the Company and, during such period, no such
employee or consultant has been terminated.

     7.17. EMPLOYEE BENEFIT PLANS. Other than as set forth in SCHEDULE 7.17, the
Company has not established, sponsored, maintained, made any contributions to or
been obligated by law to establish, maintain, sponsor or make any contributions
to any "employee pension benefit plan" or "employee welfare benefit plan" (as
such terms are defined in the Employee Retirement Income Security Act of 1974,
as amended ("ERISA")), including, without limitation, any "multi-employer plan."
Any such plans have been established and are being operated in compliance with
ERISA, and there exist no unfunded obligations of the Company with respect to
any such plan, except as could not reasonably be expected to have a Material
Adverse Effect. The Company has complied in all material respects with all
applicable laws relating to the employment of labor, including provisions
relating to wages, hours, equal opportunity, collective bargaining and the
payment of Social Security and other taxes, and with ERISA except to the extent
that noncompliance would not reasonably be expected to have a material adverse
effect on the Company, and the Company is not aware of any pending or threatened
claim against the Company with respect to the foregoing.

     7.18. INTELLECTUAL PROPERTY RIGHTS.

     (a) The Company owns, free and clear of all encumbrances, restrictions,
liens, security interests and charges, and has good and marketable title to, or
holds adequate licenses or otherwise possesses all such rights (or such rights
are in the public domain) as are necessary to use all patents (and applications
therefor), patent disclosures, trademarks, service marks, trade names,
copyrights (and applications therefor), inventions, discoveries, processes,
know-how, scientific, technical, engineering and marketing data, software code,
formulae and techniques used or proposed to be used, in or necessary for the
conduct of its business as now conducted or as

                                       10
<PAGE>

proposed to be conducted, except where the failure to have such rights
would not have a Material Adverse Effect.

     (b) The Company has not received written notice of any conflict or alleged
conflict with the rights of others pertaining to any of its tangible and
intangible assets. To the Company's knowledge, the Company's business, as
presently conducted, does not infringe upon or violate any intellectual property
rights or trade secrets of others in any material respect. To the Company's
knowledge, the Company has the right to use, free and clear of any rights or
claims of others, all intellectual property and trade secrets, processes,
customer lists and other rights to the extent reasonably necessary for the
conduct of the Company's business as presently conducted.

     (c) The Company is not currently obligated or under any existing liability
to make royalty or other payments to any owner of, licensor of, or other
claimant to, any patent, trademark, service name, trade name, copyright, or
other intangible asset, with respect to the use thereof or in connection with
the conduct of its business as now conducted, except where the failure to make
any such payments would not have a material adverse effect on the business or
financial position of the Company. To the Company's knowledge, no employee of
the Company is subject to any employment agreement or proprietary information
agreement which he or she had with a previous employer or any intellectual
property policy of such employer, which affects the rights of the Company to use
the technologies, patents, trademarks, trade secrets, service names, trade
names, copyrights, licenses and the like currently employed by the Company, or
is a party to or threatened by any litigation concerning any patents,
trademarks, trade secrets, service names, trade names, copyrights, licenses and
the like.

     7.19. TITLE TO TANGIBLE ASSETS; LEASEHOLD INTERESTS. Other than as set
forth in SCHEDULE 7.10, the Company has good and marketable title to its
tangible properties and assets and good title to all its leasehold estates, in
each case subject to no mortgage, pledge, lien, lease, encumbrance or charge,
other than, or resulting from, taxes which have not yet become delinquent and
minor liens and encumbrances which do not in any case materially detract from
the value of the property subject thereto or materially impair the operations of
the Company. The Company does not own any real property. Certain real property
used by the Company in the conduct of its business is held under lease, and the
Company is not aware of any pending or threatened claim or action by any lessor
of any such property to terminate or materially alter any such lease. Each lease
or agreement to which the Company is a party and pursuant to which the Company
holds properties and assets is a valid and subsisting agreement without any
material default of the Company thereunder and, to the best of the Company's
knowledge, without any material default thereunder of any other party thereto.
No event has occurred and is continuing which, with due notice or lapse of time
or both, would constitute a default or event of default by the Company under any
such lease or, to the best of the Company's knowledge, by any party thereto,
except for such defaults that would not individually or in the aggregate have a
Material Adverse Effect. The Company's possession of such property has not been
disturbed and, to the best of the Company's knowledge, no claim adverse to its
rights in such leasehold interests has been asserted against it.

     7.20. INSURANCE. The Company holds valid policies with reputable insurers
covering insurance in the amounts and type that the Company reasonably believes
is appropriate and customary for entities in the same or similar businesses to
that of the Company or that are otherwise required to be maintained by it and
with such deductibles or coinsurance as is customary, and such policies are in
full force and effect. The Company has timely filed claims with its insurers
with respect to all material matters and occurrences for which it believes it
has coverage. No notice of any termination or threatened termination of any of
such policies has been received by the Company and such policies are in full
force and effect.

     7.21. TRANSACTIONS WITH RELATED PARTIES. Except as disclosed on SCHEDULE
7.21, the Company is not a party to any agreement in excess of $100,000 with any
of its officers, stockholders or directors or any Affiliate of any of the
foregoing under which it: (i) leases any real or personal property (either to or
from such person), (ii) has incurred any debt for borrowed money or under which
it has lent money (other than routine travel advances), (iii) licenses
technology (either to or from such person), (iv) is obligated to purchase any
tangible or intangible asset from or sell such asset to such person, or (v)
purchases products or services from such person.

     7.22. INTEREST IN COMPETITORS. Neither the Company nor to its knowledge any
of its officers, has any interest, either by way of contract or by way of
investment (other than as holder of not more than 5% of the outstanding capital
stock of a publicly traded Person) or otherwise, directly or indirectly, in any
Person other than the Company that (i) provides any services or designs,
produces or sells any product or product lines or engages in any activity
similar to or competitive with any activity currently conducted or proposed to
be conducted by the Company or (ii) has any direct or indirect interest in any
asset or property, real or personal, tangible or intangible, of the Company.

                                       11

     7.23. REGISTRATION RIGHTS. Except for the contingent piggyback rights set
forth in this Agreement, the Company is not under any obligation to register any
of its securities under the Act.

     7.24. DISCLOSURE MATERIALS. The due diligence materials submitted to
Purchasers, when taken together with this Agreement and the Schedules hereto, do
not contain an untrue statement of a material fact or omit a material fact
necessary to make the statements contained therein not misleading. Any
disclosure on any Schedule attached hereto shall be deemed to constitute a
disclosure on all other Schedules to the extent applicable, unless such
disclosure could not reasonably be included on other Schedules from the context
of the disclosure.

     7.25. USE OF PROCEEDS. The net proceeds received by the Company from the
sale of shares of Series B Preferred Stock pursuant to this Agreement will be
used by the Company for general corporate purposes.

SECTION 8. REPRESENTATIONS AND WARRANTIES OF PURCHASERS.

Each Purchaser represents and warrants, severally and jointly, to the Company
that:

     8.1. AUTHORIZATION. The Purchaser has all requisite power, authority and
legal right to execute, deliver, enter into, consummate and perform this
Agreement. This Agreement constitutes the valid and binding obligation of
Purchaser, enforceable against Purchaser in accordance with its terms. The
execution, delivery and performance of this Agreement have been duly authorized
by all necessary action on the part of Purchaser and all consents of any third
parties that may be required to be obtained by Purchaser for the consummation of
the transactions contemplated by this Agreement have been obtained.

     8.2. INVESTMENT FOR OWN ACCOUNT. Purchaser is acquiring the Series B
Preferred Stock purchased under this Agreement (and will acquire the Common
Stock upon conversion of the Series B Preferred Stock) for its own account for
investment and not with a view towards the resale, transfer or distribution
thereof. Such Purchaser has no present intention of distributing such Series B
Preferred Stock (or the shares of the Common Stock acquired upon conversion of
the Series B Preferred Stock). No other Person has any right with respect to or
interest in the Series B Preferred Stock to be purchased by Purchaser, nor has
Purchaser agreed to give any Person any such interest or right in the future.

     8.3. OFFERING EXEMPTION. Purchaser understands that the shares of the
Series B Preferred Stock being purchased under this Agreement have not been
registered under the Act, nor qualified under any state securities laws, and
that the shares of Series B Preferred Stock are being offered and sold pursuant
to an exemption from such registration pursuant to Section 4(2) and Rule 506
promulgated under the Act and qualification based in part upon the
representations of such Purchaser contained herein.

     8.4. KNOWLEDGE AND EXPERIENCE; ABILITY TO BEAR ECONOMIC RISKS. Purchaser
has substantial knowledge and experience in financial and business matters, is
capable of evaluating the merits and risks of the investment contemplated by
this Agreement, and is able to bear the economic risk of its investment in the
Company (including a complete loss of its investment). Purchaser represents that
it is an accredited investor within the meaning of Regulation D under the Act.
Purchaser represents that it received due diligence materials and has had an
opportunity to discuss the Company's business management and financial affairs
with directors, officers and management of the Company. Purchaser has also had
the opportunity to ask questions of, and receive answers from, the Company and
its management regarding the terms and conditions of this investment.

     8.5. LIMITATIONS ON DISPOSITION. Purchaser recognizes that no public market
exists for the Series B Preferred Stock to be sold hereunder and the Common
Stock issuable upon conversion thereof, and no representation has been made to
Purchaser that any such public market will exist in the future. Purchaser
understands that it must bear the economic risk of this investment indefinitely
unless the Series B Preferred Stock (or the Common Stock issuable upon
conversion thereof) is registered pursuant to the Act or an exemption from such
registration is available, and unless the disposition of the Series B Preferred
Stock (or the Common Stock issuable upon conversion thereof) is qualified under
applicable state securities laws or an exemption from such qualification is
available (and evidence reasonably satisfactory to the Company is provided by
such Purchaser of the availability of such exemptions, including the delivery,
upon request, to the Company of an opinion of counsel to such Purchaser, which
opinion and counsel are reasonably satisfactory to the Company), and that,
except as provided herein, the Company has no obligation or present intention of
so registering the Series B Preferred Stock (or the Common Stock issuable upon
conversion thereof). Purchaser understands that there is no assurance that any
exemption from the Act will be available, or, if available, that such exemption
will allow it to dispose of or

                                       12
<PAGE>

otherwise transfer any or all of the Series B Preferred Stock or the Common
Stock issuable on conversion of the Series B Preferred Stock in the amounts or
at the times Purchaser might desire. Purchaser understands that at the present
time Rule 144 promulgated under the Act by the Securities and Exchange
Commission ("RULE 144") is not applicable to sales of the shares of Series B
Preferred Stock because such shares are not registered under Section 12 of the
Securities Exchange Act of 1934 (the "EXCHANGE ACT"), and there is not publicly
available the information concerning the Company specified in Rule 144.
Purchaser acknowledges that the Company is not presently under any obligation to
register under Section 12 of the Exchange Act or to make publicly available the
information specified in Rule 144 and that except as provided herein, is not
otherwise required to do so.

     8.6. NO GENERAL SOLICITATION. The Purchaser represents that at no time was
the Purchaser presented with or solicited by or through any leaflet, public
promotional meeting, advertisement or any other form of general or public
advertising or solicitation. In addition, the Purchaser acknowledges that there
has never been any representation, guaranty or warranty made by the Company or
any agent or representative of the Company as to the amount of or type of
consideration or profit, if any, to be realized as a result of any investment by
the Purchaser in the Series B Preferred Stock or the Common Stock issuable upon
conversion of the Series B Preferred Stock.

     8.7. PURCHASER INFORMATION. The Purchaser has discussed with his/her or its
legal, tax and financial advisors the suitability of an investment in the
Company for his/her or its particular tax and financial situation. All
information which he, she or it has provided to the Company concerning his, her
or its financial position is correct and complete as of the date of this
Agreement, and if there should be any material change in such information prior
to the Closing Date, the Purchaser agrees immediately to provide such
information to the Company and the Agent.

company or other entity, then the office or offices of Purchaser in which its
investment decision was made is located at the address or addresses of Purchaser

States, he, she or it understands that it is his/her or its responsibility to

and statement of cash flows of the Company as at the close of such quarter and
covering operations for such quarter, and the portion of the Company's fiscal

with such financial statements has been made in accordance with generally
accepted auditing standards, and accordingly included such tests of the
accounting records and such other auditing procedures as were considered
necessary in the circumstances.

CONFIDENTIALITY.

     (a) Each Purchaser covenants for itself, and, as applicable, for its
directors, officers, affiliates and partners, that it will use due care to
prevent its officers, directors, partners, employees, counsel, accountants and
other representatives from disclosing any information and other material
furnished under or in connection with this Agreement to persons other than their
respective authorized employees, counsel, accountants, stockholders, partners,
limited partners and other authorized representatives. Notwithstanding the
foregoing, if Purchasers are advised by such counsel that such disclosure or
delivery is required by law, regulation or judicial or administrative order,
then they may disclose or deliver such information after giving written notice
to the Company of such requirements. To the extent practicable, Purchasers shall
provide notice to the Company prior to disclosure or delivery required by law,
regulation or judicial or administrative order.

     For purposes of this SECTION 11.2(a), "DUE CARE" means at least the same

for purposes of the Exchange Act, Purchasers agree not to engage in any purchase
or sale of securities while in possession of such information and prior to the
time that such information is made generally known to the public and Purchasers
agree to use due care to prevent their officers, directors, partners, employees,
counsel and other representatives, who have been given access to such material,
nonpublic information, from engaging in any such purchase or sale during such
period.

     (c) Subject to the following sentence, any public disclosures, including
press releases, regarding this transaction or the investment by Bluestone in the
capital stock of the Company shall be mutually agreed upon by Bluestone and the
Company. Bluestone may, in its reasonable discretion, disclose such information
about the transactions contemplated hereby without prior approval of the Company
if, in the opinion of Bluestone's counsel, disclosure of such information is
required by law or rules of the Nasdaq Stock Market. Bluestone shall use all
reasonable efforts to give the Company prior notice of such disclosure. Both
parties may make such disclosures as appear reasonably necessary to employees,
agents, representatives, and service providers assisting it or otherwise
involved in this transaction who are covered by non-disclosure agreements and
who are on a "need to know" basis.

     11.3. RESALE OF SECURITIES.

     (a) Each Purchaser covenants that it will not sell or otherwise transfer
the Series B Preferred Stock (or any shares of Common Stock acquired upon the
conversion of shares of Series B Preferred Stock) except pursuant to an

of counsel reasonably satisfactory to the Company, qualifies as an exempt
transaction under the Act and the rules and regulations promulgated thereunder
and any applicable state securities laws, and such Purchaser will deliver to the
Company evidence reasonably satisfactory to the Company of the availability of
such exemptions, including the delivery, upon request, to the Company of an
opinion of counsel to such Purchaser.

     THIS AGREEMENT, made this 9th day of August, A. D., Two Thousand (2000)
between PARKERS CREEK, II, L.L.C., a New Jersey Limited Liability Company, with
offices at 365-B New Albany Road, Moorestown, New Jersey, 08057-1117, Party of
the First Part, hereinafter called "Landlord", and BLUESTONE SOFTWARE, INC., a
Delaware Corporation licensed to do business in the State of New Jersey, with
Corporate Offices located at Airport Business Park, 300 Stevens Drive, Lester,
Pennsylvania, 19029, Party of the Second Part, hereinafter called "Tenant".

     WITNESSETH, that in consideration of the covenants herein contained, the
Landlord does hereby demise, lease and let to the Tenant, and the Tenant does
hereby hire and rent from the Landlord, premises located at Briggs Road
Industrial Park, 6000 Irwin Road, Mount Laurel, New Jersey, 08054, consisting of
approximately 46,250 square feet. More particularly described on Exhibit "A"
attached hereto and made a part hereof.

     For a term of Seven (7) Years commencing November 1, 2000 (See Item
Twenty-Fifth) and expiring on October 31, 2007, at the base monthly rental as
follows:

     FORTY-EIGHT THOUSAND NINE HUNDRED FORTY-SEVEN AND 92/100 DOLLARS
     ($48,947.92) per month ($12.70 per square foot) for the period November 1,
     2000, through October 31, 2007; plus 1/12th of the estimated annual taxes
     and insurance, sewer and water, sprinkler standby and inspection fees,
     landscaping and yard maintenance, parking lot cleaning, striping and
     maintenance, etc., hereinafter called escrow expense, on the premises,
     monthly, currently estimated to be $9,635.42 per month ($2.50 per square
     foot). (SEE ITEM TWENTIETH).

     There shall be a late charge of $500.00 for each payment that shall not
have been received within ten (10) days of the due date. Rent is payable
monthly, in advance, on the first day of each and every month (except the first
month's rent as Tenant agrees to pay the first month's rent in advance upon
execution hereof) to Parkers Creek, II, L.L.C., at 365-B New Albany Road,
Moorestown, New Jersey, 08057-1117.

     As security for the faithful performance by Tenant of all the terms and
conditions upon the Tenant's part to be performed, Tenant will deposit an amount
equal to one month's rent and escrow expense equal to FIFTY-FIVE THOUSAND AND
00/100 DOLLARS ($55,000.00), which sum shall be returned to Tenant, without
interest, on the day set forth for the expiration of the term herein or any
extension herein provided, however, that Tenant has fully and faithfully carried
out all of the material terms, covenants, and conditions on its part to be
performed. Landlord shall have the right to apply any part of said deposit to
cure any default of Tenant and, if Landlord does so, Tenant shall deposit with
Landlord the amount so applied so that the Landlord shall have the full deposit
on hand at all times during the term of this Lease or any extension hereof.

     This Lease shall continue after the initial term unless and until
terminated by either party, which termination may be effected by either party
giving to the other party written notice thereof on or before ninety (90) days
prior to the termination of the Lease. In default of such notice, this Lease,
with all the conditions and covenants thereof, shall continue for the further
period of one (1) year, at a monthly rate equal to 115% of the last month's rent
payable hereunder, and shall continue so on from year to year unless and until
terminated by either party giving to the other party at least ninety (90) days
written notice of its intention to terminate said Lease prior to the expiration
of the current term. Provided, however, that if the Landlord shall have given
such written notice ninety (90) days prior to the expiration of any term hereby
created of its intention to change the terms and conditions of this Lease, and
Tenant shall hold over after the expiration of the time mentioned in such
notice, Tenant shall be considered Tenant under the terms and conditions
mentioned in such notice for such further period as Tenant may remain in
possession of the demised premises or until similar subsequent notice is given
by Landlord, again changing the said terms and conditions.

     FIRST. Landlord covenants to deliver possession of the demised premises to
Tenant on or before the beginning of the term substantially ready for occupancy
by Tenant free and clear of all tenancies and occupancies and to provide Tenant
with a copy of the current temporary or final Certificate of Occupancy
("Certificate") issued by the appropriate municipal authorities evidencing
Tenant's right to lawfully occupy the demised premises. Tenant agrees not to
occupy the premises until such time as a temporary or final Certificate is
issued. In the event that the demised premises and temporary Certificate have
not been so delivered to Tenant at the beginning of the term of this Lease as
herein provided, then the obligation of Tenant to pay rent shall abate until the
demised premises and temporary Certificate are so delivered to Tenant. In the
event a temporary

                                       1
<PAGE>

Certificate is issued, Landlord, at its expense, shall complete all work and
fulfill all requirements necessary for the municipality to issue a permanent
Certificate prior to the expiration of the temporary Certificate. Tenant hereby
covenants to pay upon due date thereof all rents or any changes herein included
as rent. If at any time the rent payable herein shall remain unpaid for a period
of ten (10) days after written notice is given by Landlord as herein provided,
or should the Tenant be declared insolvent or bankrupt, make an assignment for
the benefit of creditors, or if a receiver is appointed for all or substantially
all of Tenant's assets; then, at the option of the Landlord, the rent for the
balance of the term shall thereupon become due and payable and the Landlord
shall have the full power and authority to institute any action at law or equity
for the collection of said rent and the Landlord may declare the said term ended
and re-enter the demised premises.

     Tenant agrees that if at any time during the continuance of this Lease,
Tenant removes or attempts to remove Tenant's goods or property out of or from
the demised premises excepting in the ordinary course of business without first
having paid and satisfied Landlord in full for all rent which may become due
during the entire term of this Lease then, and in such case, such removal or
attempt to remove shall require that the whole rent for the said term then
remaining unpaid shall, at the option of the Landlord, be taken to be thereupon
due and payable and in arrears and Landlord shall have full power and authority
to institute any action at law or in equity for the collection of rents due or
to become due or to proceed by distress or any other process of law to collect
the same or, at the Landlord's option, may declare the said term ended and
re-enter the demised premises and every part thereof, and remove all persons or
things therefrom, or to proceed by action for the recovery thereof or otherwise.
All in accordance with the laws of the State of New Jersey.

     SECOND. Tenant shall not do, suffer to be done, keep, or suffer to be kept
anything in, upon or about the demised premises which will contravene Landlord's
policies insuring against loss or damage by fire or other hazards including, but
not limited to, public liability policies, or which will prevent Landlord from
procuring such policies in responsible companies licensed in New Jersey. If
anything be done, omitted to be done or suffered to be done by Tenant, kept or
suffered by Tenant to be kept in, upon or about the demised premises which shall
cause an increase in the rate of fire or other insurance from responsible
insurance company on the demised premises or adjacent premises of which the
demised premises is a part, then Tenant shall be responsible for the total of
such increase resulting from its use and/or occupancy.

     Landlord shall purchase and maintain hazard insurance on the building
comprising the demised premises ("Building") in an amount not less than the full
replacement cost of the Building. All proceeds of such insurance shall be
payable directly and solely to Landlord, its assigns or mortgages, and Tenant
shall have no interest therein or rights with respect thereto.

     THIRD. The Tenant shall pay all sums for electric and gas and the accounts
covering those utilities shall be placed in Tenant's name prior to occupancy. In
the event such utilities have not been transferred prior to occupancy, Tenant
shall reimburse Landlord for its pro rata share of same.

     Unless Tenant is occupying entire building, Tenant shall use, in common,
the parking facilities as provided for by Landlord, subject to such reasonable
rules and regulations for parking as Landlord may promulgate for all Tenants and
which Tenant is made aware. Tenant shall at all times comply with and fulfill
any requirements promulgated by any state, county, municipal authorities or
insurance carriers with respect to the use and/or occupancy of the demised
premises. No overnight parking of any unlicensed or unregistered vehicles.
Landlord reserves the right to restrict Tenant's parking to a maximum of
approximately 185 spaces. (See Item Thirty-Seventh).

     FOURTH. Tenant shall be permitted to make alterations to the demised
premises with the prior consent of Landlord, which shall not be unreasonably
withheld. All alterations shall: (a) be performed in a good and workmanlike
manner in conformity with all laws, regulations, rules, ordinances and other
requirements of all governmental authorities having jurisdiction; (b) be
commenced only after all required municipal and other governmental permits,
authorizations and approvals shall have been obtained by Tenant, at its own cost
and expense, provided that Landlord will promptly execute and return any
documents necessary to be signed by Landlord to obtain any such permits,
authorizations and approvals; (c) be of such a character as to not reduce the
value of the demised premises; (d) not impair or otherwise jeopardize, in any
way, the structural integrity of the Building; (e) not adversely affect the
structural components of the Building and (f) not adversely affect any of the
plumbing, electrical and HVAC systems within the Building. Tenant, with
Landlord's written approval, shall have the right to erect in and about the
demised premises such signs as may be reasonably necessary to identify and
advertise its occupancy and its business. The consent of the Landlord to the
foregoing shall not be unreasonably withheld.

                                       2
<PAGE>

     FIFTH. The Tenant shall pay all personal property taxes and other taxes and

the amount proposed by Kay Construction for the interior fit-out is excessive,
then Tenant may seek alternative bids or estimates for construction of the
Tenant Work by any responsible, bondable third party, general contractor or
sub-contractor. Any delay in the estimated time of completion of the building as
a result of the extended bidding process, finalizing contracts, obtaining
building permits, or contractor delays as a result of a successful bidder other
than Kay Construction will not delay the commencement date of the rent payment.

     Landlord shall not commence the Tenant Work until approval of the proposed
budget by Tenant, which approval shall not be unreasonably withheld.

     Landlord's Work (as hereinafter defined) includes completion of all
exterior site work, landscaping, paving, site lighting, including completion of
exterior entrance doors and windows in front and rear walls, concrete slab,
roof, three (3) overhead doors, underground electric service to the building
(Primary 800 AMP), secondary power terminated at electric meter, telephone
conduit to utility room, domestic water, fire sprinkler, installation of
sprinkler drops to ceiling height, fire sprinkler standby service water main to
sprinkler room, roof-top heating and air conditioning equipment and distribution
duct work excluding dedicated computer room special HVAC equipment, all at
Landlord's expense.

     Any additional windows or openings in either of the existing side (end)
walls shall be included within the Tenant Work.

     The balance of all Tenant required interior work including sheetrock walls,
floor covering, ceiling, mechanical and electrical systems, etc. are all part of
Landlord's fit-out allowance and the Tenant Work. The Landlord fit-out allowance
and Tenant Work do not include cubicles, artwork, decorating, etc. which shall
be done separately by Tenant.

     Within ten (10) days from execution hereof, Tenant will provide and
maintain either an irrevocable letter of credit, bond, guaranty or other
negotiable instrument acceptable to Landlord in the amount of any unreimbursed
interior fit-out expenses. The face amount of said instrument shall reduce by
approximately one-seventh (1/7th) annually.

     THIRTY-FIFTH. Upon execution of this Lease, the Tenant and Landlord will
commence to prepare a complete set of construction documents for the interior
fit-out of the space. The Landlord anticipates a Tenant fit-out construction
sequence of approximately 12 weeks from the receipt of the Mt. Laurel Township
approved construction plans and permits. The Landlord and Tenant hereby agree to
execute a Lease Modification Agreement following Tenant's occupancy reflecting
the actual occupancy date if different from November 1, 2000 and Lease shall be
modified to reflect the actual date premises is available for Tenants'
occupancy.

     Landlord shall perform, at its expense, subject to the limitations set
forth in Item Thirty-Fourth above, all of the work relating to the construction
and finishing of the demised premises in accordance with the Plans that are to
be approved and agreed to in writing by Tenant and Landlord ("Landlord's Work").

     Landlord represents to Tenant that for a period of one (1) year after the
commencement date that the Landlord's Work, the demised premises, and the
systems and equipment which are part of Landlord's Work, shall be in good
working order and condition and free from any and all defects. Tenant shall give
written notice to Landlord within such one (1) year period of any condition of
the demised premises which Tenant reasonably determines to be defective or other
than as represented by Landlord herein. Landlord will, within ten (10) days
after receipt of such notice from Tenant, repair any such defective condition at
Landlord's sole cost and expense. In addition, Landlord shall assign to Tenant
all warranties and/or guaranties with respect to the Landlord's Work. On the
commencement date, Landlord and Tenant shall inspect the demised premises and
prepare a list of minor and insubstantial construction items to be completed
("Punch List Items"). The Punch List Items shall be completed by the Landlord,
at its sole cost and expense, within thirty (30) days following the commencement
date.

     Notwithstanding anything to the contrary contained in this Lease, in the
event Landlord has not obtained the building permits and other zoning and/or
land development improvement approvals from all state and local governmental
authorities and/or instrumentalities necessary to commence construction of
Landlord's Work in accordance with the Plans within sixty (60) days following
execution of this Lease by both parties and delivery of Tenant's plans to
Landlord to be complete for approval by construction official in accordance with
municipal requirements, then either Landlord or Tenant shall have the right to
terminate this Lease upon written notice to the other, whereupon this Lease
shall become NULL AND VOID and neither party shall have any further obligations
hereunder.

     THIRTY-SIXTH. Provided Tenant is not and has not been in material default
for over thirty (30) days hereunder, and shall have formally notified Landlord
of its need for additional space in this area, Landlord shall first offer any
vacant space owned by Landlord in the immediate vicinity of leased premises to
Tenant herein

                                       10

prior to entering into a lease with a third party. If an existing tenant in the
building has a prior option to expand into adjacent space, this right of first
refusal shall be subject to the prior option.

     After notice to Tenant of available space, Tenant shall have five (5) days
to exercise its right hereunder or this right of first refusal for additional
space shall terminate.

     THIRTY-SEVENTH. The base design of the Site Plan for the proposed building
contained approximately 185 parking spaces as originally designed. The Tenant
has a future need for additional parking and upon the request of Tenant,
Landlord agrees to expand the parking lot to the area shown on Exhibit "A"
(Concept Site Plan) as "future parking and aisle area". The parties agree that
the Landlord will complete that area, which will provide not less than 75
additional parking spaces. Said work is to be done either concurrent with
completion of the fit-out or immediately after, whichever is the most
expeditious way to handle with Township officials, but in no event shall
construction of the additional parking commence later than thirty (30) days
following receipt of all required governmental approvals. Landlord agrees that
the additional cost of said parking area shall not exceed the estimated cost of
approximately $75,000.00. The cost of said work is to be divided equally between
the Landlord and Tenant. Landlord and Tenant agree that Tenant shall reimburse
Landlord for one-half (1/2) of the total cost of said work (not more than
$37,500.00) immediately upon completion and acceptance by the Township of said
parking area. In the event that the fit-out costs for the interior of the
building are less than $20.00 per square foot, the Tenant's share of the parking
lot cost may be included as part of the interior fit-out cost.

     THIRTY-EIGHTH. The final Lease execution by all parties to this Agreement
is contingent upon approval of the Business Grant by the New Jersey Economic
Development Authority. The Tenant hereunder is responsible for the application.
The Landlord shall not commence any portion of the plans, permits or Tenant
fit-out until such time as this contingency is satisfied or waived by the
Tenant.

     THIRTY-NINTH. This Lease sets forth all the covenants, promises,
agreements, conditions and understandings between the Landlord and the Tenant
concerning the leased premises and there are no covenants, promises, agreements,
conditions or understandings, either oral or written, between the parties other
than those set forth herein. Except as otherwise provided, no subsequent
alterations, amendments, changes or additions to this Lease Agreement shall be
binding upon the Landlord or Tenant unless reduced to writing and agreed to and
signed by an authorized representative of Landlord and an authorized officer of
Tenant. If any term or provision of this Lease Agreement is to any extent
invalid or unenforceable, the remaining terms and provisions of this Lease
Agreement will not be affected thereby, but each term and provision of this
Lease Agreement will be valid and be enforceable to the fullest extent permitted
by law.

     IN WITNESS WHEREOF, the parties hereto have caused these presents to be
signed by their corporate officers and caused the proper corporate seals to be
affixed, the day and year first above written.
