         3.09     Proprietary Rights.
                  ------------------

                  (a) Schedule 2.01 hereto contains a complete and correct list
of all Intellectual Property owned or used by Seller and each Seller Sub (other
than generally available "off-the-shelf" computer software), as well as all
registrations thereof and applications therefor, and each license and agreement
relating thereto. Except as indicated on Schedule 2.01, all of Seller's and
Seller Subs' patents, patent applications, registered trademarks, trademark
applications, registered copyrights and any other intellectual property subject
to application and/or registration issued by any state, government or other
public legal entity included in the Intellectual Property are valid and in full
force and effect and remain in good standing with all fees and filings paid as
of the date hereof and consummation of the transaction contemplated hereby will
not alter or impair any such rights. To the knowledge of Seller and each of the
Seller Subs, except as set forth on Schedule 3.09 hereto, there is no violation
by others of any right of Seller or any Seller Sub (and to the extent utilized
in the Business, Seller) with respect to any Intellectual Property, and Seller
and any of the Seller Subs is not infringing upon, misappropriating or violating
any third party's rights that would pertain to the Business. No proceedings have
been instituted or are pending or, to the knowledge of Seller or any of the
Seller Subs, threatened, nor any claims made alleging any such violation or
challenging or questioning the validity, enforceability or effectiveness of the
Intellectual Property. Neither Seller nor any of the Seller Subs have entered
into any agreement to indemnify any other person against any charge of
infringement of any Intellectual Property, other than indemnification provisions
contained in standard sales or license agreements to end users arising in the
ordinary course of business, the forms of which are attached hereto on Schedule
3.09(a).

                  (b) The Intellectual Property contains only those items and
rights which are: (i) owned by Seller or any Seller Sub; (ii) in the public
domain; or (iii) rightfully used by Seller or any Seller Sub pursuant to a valid
and enforceable license or other agreement (the "Licensed Intellectual
                                                 ---------------------
Property"), the parties, date, term and subject matter of each such license or
--------
other agreement (each, a "License Agreement") being set forth on Schedule
                          -----------------
3.09(b). Seller and each Seller Sub owns all right, title and interest in and to
the Intellectual Property, or has valid and sufficient licenses to all rights in
the Intellectual Property necessary to carry out Seller's and the Seller Subs
respective current Business activities free and clear of all liens, claims and
encumbrances, including without limitation, to the extent required to carry out
such activities, rights to make, use, reproduce, modify, adopt, create
derivative works based on, translate,

                                       11

<PAGE>

distribute (directly and indirectly), transmit, display and perform publicly,
license, rent and lease and, except with respect to the Licensed Intellectual
Property, assign and sell, the Intellectual Property. Seller and the Seller Subs
are the exclusive owners of all Trademark Rights used in connection with the
operation or conduct of the business of Seller and the Seller Subs, including
the provision of any services by Seller or any of the Seller Subs.

                  (c) Schedule 3.09(c) contains a true and complete list of all
software programs owned or used by Seller and each of the Seller Subs, other
than software programs which are readily commercially available or for which
substitutes are available from more than one source (the "Software Programs").
                                                          -----------------
Seller and each Seller Sub, as the case may be, owns full and unencumbered right
and good and marketable title to such Software Programs which it owns, free and
clear of all mortgages, pledges, liens, security interests, conditional sales
agreements, encumbrances or charges of any kind. Seller and the Seller Subs have
full and unrestricted rights to use the Software Programs that they license
pursuant to the License Agreements.

                  (d) The Software Programs are free of any disabling codes that
may be used to access, modify, delete, damage or disable any Systems (as defined
below) or that may result in impaired usage thereof or damage thereto. Seller
and the Seller Subs have taken reasonable steps and implemented reasonable
procedures to ensure that its internal computer systems used in connection with
the Business consisting of hardware, software, databases or embedded control
systems ("Systems") are free from disabling codes. The Systems' components used
          -------
in connection with the Business obtained by Seller or any Seller Sub from third
party suppliers are, to the best of knowledge of Seller or any Seller Sub, free
of any disabling codes that may, or may be used to, access, modify, delete,
damage or disable any of the Systems or that might result in damage thereto.
Except as may be set forth in Schedule 3.09(d), Seller and each of the Seller
Subs have in place appropriate disaster recovery plans and procedures and has
taken reasonable steps to safeguard their Systems and restrict unauthorized
access thereto. Seller and each Seller Sub have provided, or will provide prior
to the Closing, to Buyer an accurate list of all errors or "bugs" in the
Software Programs which are contained in the computer databases which Seller and
the Seller Subs maintain for the purpose of tracking errors and "bugs" in the
Software Programs.

                  (e) Neither Seller nor any of the Seller Subs is a party to
any agreement pursuant to which any third party has any right to manufacture,
reproduce, distribute, market or exploit any of the Intellectual Property or any
adaptations, translations, or derivative works based on the Intellectual
Property or any portion thereof. Except with respect to the rights of third
parties to any Licensed Intellectual Property, no third party has rights to
manufacture, reproduce, distribute, market or exploit any works or materials of
any portion of the Intellectual Property if such portion of the Intellectual
Property constitutes a "derivative work" (as that term is defined in the United
States Copyright Act, Title 17, U.S.C. Section 101) of an underlying work of
authorship. Except as set forth in Schedule 3.09(e), neither Seller nor any
of the Seller Subs owe nor will owe any royalties or other payment to third
parties in respect of the Intellectual Property. All royalties or other payments
that have accrued prior to the Closing Date have been paid.

                  (f) All designs, drawings, specifications, source code, object
code, documentation, flow charts and diagrams incorporating, embodying or
reflecting any of the Intellectual Property at any stage of their development
were written, developed and created

                                       12

<PAGE>

solely and exclusively by employees of Seller or the Seller Subs without the
assistance of any third party or entity or were created by third parties who
assigned ownership of their rights to Seller or Seller Subs pursuant to valid
and enforceable consultant confidentiality and invention assignment agreements.
Seller and each of the Seller Subs have at all times treated the Intellectual
Property as containing trade secrets and have not disclosed or otherwise dealt
with such items in such a manner as to cause the loss of such trade secrets by
release into the public domain, including without limitation, the use of
confidentiality agreements with all of its employees having access to the
Intellectual Property and the use of licenses with all individuals or entities
provided access to the Intellectual Property containing provisions restricting
copying and prohibiting decompiling or disassembly of the Intellectual Property.
Given the nature of the Business, to the knowledge of Seller and each Seller
Sub, no employee of Seller or any of the Seller Subs is in violation of any term
of any employment contract, patent disclosure agreement or any other contract or
agreement with respect to (i) the Intellectual Property or (ii) the relationship
of any such employee with Seller, any Seller Sub or any other party. No current
officer, director, employee, consultant or independent contractor of Seller or
any of the Seller Subs has and, to the knowledge of the Seller and each of the
Seller Subs, no former officer, director, stockholder, employee, consultant or
independent contractor has any right, claim or interest in or with respect to
any Intellectual Property.

         3.10 Books and Records. All of the books and records of Seller and each
              -----------------
Seller Sub relating to the Purchased Assets have been made available to Buyer
prior to the execution of this Agreement and contain a true and complete record,
in all material respects, of the business, operations, financial condition,
results of operations, assets and liabilities relating to the Purchased Assets.
Neither Seller nor any Seller Sub has any books and records recorded, stored,
maintained, operated or otherwise wholly or partly dependent upon or held by any
means (including any electronic, mechanical or photographic process, whether
computerized or not) that are not under the exclusive ownership and direct
control of Seller or the respective Seller Sub.

accordance with their respective terms, except as may be limited by any

general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

         4.03     Non-Contravention. The execution, delivery and
                  -----------------

                                   Article V

                            COVENANTS OF the parties

         5.01     Best Efforts; Further Assurances.
                  --------------------------------

                  (a) Subject to the terms and conditions of this Agreement and
except as otherwise set forth in this Agreement, each party will use its best
efforts to take, or cause to be taken, all actions and to do, or cause to be
done, all things necessary or desirable under applicable laws and regulations to
consummate the transactions contemplated by this Agreement. Seller (for itself
and or behalf of all Seller Subs who will be transferring Purchased Assets) and
Buyer each agree to execute and deliver such other documents, certificates,
agreements and other writings and to take such other actions as may be necessary
or desirable in order to consummate or implement expeditiously the transactions
contemplated by this Agreement and to vest in Buyer title to the Purchased
Assets as provided herein. Promptly after the Closing Date, but no more than
thirty calendar days thereafter, to the extent permitted under applicable law,
Seller will provide Buyer with copies of all forms of agreements, including
those individually amended by hand or otherwise, related to the Option Assets.

                  (b) Seller (for itself and or behalf of all Seller Subs who
will be transferring Purchased Assets) hereby constitutes and appoints,
effective as of the Closing Date, Buyer and its successors and assigns as the
true and lawful attorney of Seller with full power of substitution in the name
of Buyer or in the name of Seller, but for the benefit of Buyer, except as
otherwise contemplated hereby, (i) to collect for the account of Buyer any items
of Purchased Assets and (ii) to institute and prosecute all proceedings which
Buyer may in its sole discretion deem proper in order to assert or enforce any
right, title or interest in, to or under the Purchased Assets, and to defend or
compromise any and all actions, suits or proceedings in respect of the Purchased

                                       14

<PAGE>

Assets. Buyer shall be entitled to retain for its account any amounts collected
pursuant to the foregoing powers, including any amounts payable as interest in
respect thereof.

         5.02     Certain Filings. Seller and Buyer shall cooperate with one
                  ---------------
another and shall use all reasonable efforts and take all reasonable steps to
obtain all consents, approvals, waivers or other documents from any third
parties, including any governmental authorities, and make all filings,
registrations and other notifications, as may be required to consummate the
transactions contemplated by this Agreement and, in taking such actions or
making any such filings, furnishing information required in connection therewith
and seeking timely to obtain any such actions, consents, approvals or waivers.

         5.03     Confidentiality. The parties hereto shall comply with, and
                  ---------------
shall cause their respective Representatives to comply with, all of their
respective obligations under the Confidentiality Agreement with respect to the
information disclosed pursuant to this Agreement provided however, that, the
parties shall be permitted to make such disclosures as they shall reasonably
determine are, and to the extent, required by law.

         5.04     Covenant Not To Compete.
                  -----------------------

                  (a) Seller and each Seller Sub covenant and agree that, except
as permitted under this Section 5.04, for a period of three years after the
Closing Date, it will not, and, in the case of Seller, will cause its
Subsidiaries not to, engage in the Business anywhere in the world other than the
United States of America, its territories and possessions and the Excluded
Territories; provided, however, that (i) nothing herein shall be construed to
prevent Seller from owning as a passive investor up to five percent (5%) in any
person that engages in the Business, and (ii) Seller's having entered into the
Excluded Agreement shall not constitute a violation of this Section 5.04.

                  (b) It is the desire and intent of the parties that the
provisions of this Section 5.04 shall be enforced to the fullest extent
permitted under the laws and public policies of each jurisdiction in which
enforcement is sought. If any court determines that any provision of this
Section 5.04 is unenforceable, such court shall have the power to reduce the
duration or scope of such provision, as the case may be, or terminate such
provision and, in reduced form, such provision shall be enforceable; it is the
intention of the parties that the foregoing restrictions shall not be
terminated, unless so terminated by a court, but shall be deemed amended to the
extent required to render them valid and enforceable, such amendment to only
apply with respect to the operation of this Section 5.04 in the jurisdiction of
the court that has made the adjudication.

                  (c) The parties acknowledge and agree that the restrictions
contained in this Section 5.04 are a reasonable and necessary protection of the
immediate interest of Buyer, and any violation of these restrictions would cause
substantial injury to Buyer and Buyer would not have entered into this Agreement
without receiving the additional consideration offered by Seller and the Seller
Subs in binding itself to these restrictions. In the event of a breach or a
threatened breach by Seller or any of its Subs of these restrictions, Buyer
shall be entitled to apply to any court of competent jurisdiction for an
injunction restraining such person from such breach or threatened breach
(without the necessity of providing the inadequacy of money damages as a
remedy); provided, however, that the right to apply for injunctive relief shall
not be construed as

                                       15

<PAGE>

prohibiting Buyer from pursuing any other available remedies for such breach or
threatened breach.

         5.05     Mail and Communications. Seller will promptly remit to Buyer
                  -----------------------
any mail or other communications received by Seller relating to the Business or
the Purchased Assets and any invoices received by Seller relating to Assumed
Liabilities which are received by Seller from and after the Closing Date. Buyer
will promptly remit to Seller any mail or other communications, including,
without limitation, any written inquiries and payments received by Buyer
relating to the Excluded Assets or to any business or activity of Seller other
than the Business, and any invoices received by Buyer relating to liabilities of
Seller other than the Assumed Liabilities which are received by Buyer from and
after the Closing Date.

         5.06     Public Announcements. Buyer and Seller shall consult with each
                  --------------------
other before issuing any press release concerning this Agreement or the
transactions contemplated hereby or otherwise making any public statements with
respect to this Agreement or the transactions contemplated hereby, and shall not
issue any such press release or make any such public statement without the prior
written consent of the other (which shall not be unreasonably withheld), except
to the extent required by applicable Law or the requirements of the rules and
regulations of the SEC or the NNM, in which case the issuing party shall use all
reasonable efforts to consult with the other party before issuing any such
release or making any such public statement. The initial press release
concerning the transactions contemplated hereby shall be a joint press release
approved by the parties to this Agreement.

         5.07     Taxes.
                  -----

                  (a) Seller shall pay all Taxes imposed upon Seller. Seller
shall also pay, or reimburse Buyer for, all Taxes imposed on Buyer or any
affiliate of Buyer and any Taxes to which the Purchased Assets are subject or
for which a lien, claim or encumbrance can be placed upon the Purchased Assets
but only in each case to the extent that any such Taxes relate to periods (or
portions thereof) ending on or prior to the Closing Date or transactions or
events occurring on or prior to the Closing Date and only to the extent related
to the Business and including any sales or transfer taxes pertaining to the
Acquisition regardless of which party may be the legal obligor under applicable
law. Liability for any Taxes that Seller is required to satisfy pursuant to this
Section 5.07 shall not constitute or be treated as Assumed Liabilities.

                  (b) With respect to state and local ad valorem taxes on the
Purchased Assets (whether personal or real, owned or leased) for the current Tax
year, Seller shall be responsible for the payment of all such Taxes for the
period up to and including the Closing Date and Buyer shall be responsible for
the payment of all such Taxes for the period after the Closing Date. For all
purposes of this Agreement, (i) all such Taxes assessed on an annual basis shall
be prorated on the assumption that an equal amount of Tax applies to each day of
the year, regardless of how installment payments are billed or made and (ii) any
supplemental property Taxes or assessments which arise out of a revaluation of a
Purchased Asset which revaluation would not have occurred except for the change
in ownership of the Purchased Asset shall be allocated to periods after the
Closing Date and shall accordingly be borne by Buyer.

                                       16

<PAGE>


               (c)  Buyer agrees to take all actions reasonably requested by
Seller to minimize any sales, use and other transfer taxes and fees incurred in
connection with the assignment, conveyance, transfer and/or delivery of the
Purchased Assets hereunder (collectively, the "Sales Taxes"), including, without
limitation the transfer via means of electronic transmission of all assets
capable of being so transmitted. Buyer further agrees to deliver all
certificates reasonably requested by Seller to verify the fact of such
electronic transmissions or other actions. Seller shall be responsible for the
payment of the amount of any Sales Taxes.

         5.08  Cooperation and Records Retention. Seller and Buyer shall (i)
               ---------------------------------
each provide the other with such assistance as may reasonably be requested by
them in connection with the preparation of any Tax Returns, or in connection
with any audit or other examination by any taxing authority or any judicial or
administrative proceedings relating to liability for Taxes, (ii) each retain and
provide the other, with any records or other information which may be relevant
to any such Tax Return, audit or examination, proceeding or determination, and
(iii) each provide the other with any final determination of any such audit or
examination, proceeding or determination that affects any amount required to be
shown on any Tax Return of the other for any period. Without limiting the
generality of the foregoing, Seller and Buyer shall retain, until the applicable
statute of limitations (including any extensions) have expired, copies of all
Tax Returns, supporting work schedules and other records or information which
may be relevant to such Tax Returns for all tax periods or portions thereof
ending before or including the Closing Date and shall not destroy or otherwise
dispose of any such records without first providing the other party with a
reasonable opportunity to review and copy the same. Buyer shall keep the
original copies of the records and, at Seller's expense, shall provide copies of
the records to Seller upon Seller's request.
