                     MASTER PROFESSIONAL SERVICES AGREEMENT
                              INIVISIBLE IT, INC.

This Master Software Professional Services Agreement (the "Agreement") is made
and entered into as of May 20, 2002 (the "Effective Date"), by and between
INVISIBLE IT, INC., a Delaware corporation ("INVISIBLE IT"), and ALIGN
TECHNOLOGY, INC., a Delaware corporation ("ALIGN").

In consideration of the covenants and conditions hereinafter set forth, ALIGN
and INVISIBLE IT agree as follows:

1.      Services. INVISIBLE IT shall perform services to be assigned to ALIGN as
        per Section 4 of this Agreement that are described on the Schedules as
        may be attached hereto from time to time by mutual written agreement of
        the parties (the "WORK") in accordance with the terms and conditions of
        this Agreement, and on the price, delivery dates and specifications
        described in the applicable Schedule for the WORK. The Schedules shall
        be in the form attached hereto and shall be signed by both parties,
        consecutively numbered (i.e., Schedule A-1, A-2, A-3, etc.), and
        attached to this Agreement. INVISIBLE IT is not obligated to perform any
        WORK hereunder and ALIGN has not contracted for any WORK unless and
        until a Schedule is executed by both parties and attached hereto.

2.      Payment. ALIGN shall pay INVISIBLE IT for the WORK as described on the
        applicable Schedule for such WORK. For fixed fee WORK ALIGN agrees to
        remit payment in advance of the performance of such WORK or on other
        terms agreeable to both parties. For hourly WORK, VISIBLE IT agrees to
        submit to ALIGN, invoices with a brief description of the WORK
        performed, total time expended and amounts due to INVISIBLE IT on
        bi-weekly intervals and ALIGN agrees to remit payment to INVISIBLE IT
        within thirty (30) days of receipt of a INVISIBLE IT invoice for hourly
        WORK.

3.      Non-Disclosure. Each party expressly undertakes to retain in confidence
        all information and know-how transmitted by the disclosing party to the
        receiving party and that has been designated as proprietary and/or
        confidential or that, by the nature of the circumstances surrounding the
        disclosure, ought in good faith to be treated as proprietary and/or
        confidential ("Confidential Information"), and the receiving party will
        make no use of such information and know-how except under the terms and
        during the existence of this Agreement. Each party's obligation under
        this Section 3 with respect to any particular information shall extend
        to the earlier of such time as such information is publicly available
        through no fault of the receiving party for five (5) year following
        termination of this Agreement. INVISIBLE IT certifies that it will
        comply with all applicable provisions of Insurance Portability and
        Accountability Act (HIPAA).

4.      Ownership of WORK; Assignment of Rights to ALIGN.

        (a) ALIGN agrees that all systems, programs, INVISIBLE IT specifications
            and other materials and hardware, and all intellectual property
            incorporated therein (collectively referred to as "INVISIBLE IT
            Information") owned by INVISIBLE IT or licensed to INVISIBLE IT by
            third parties prior to the execution of this Agreement and used in
            conjunction with the Services for ALIGN shall continue to belong to
            INVISIBLE IT or their third party licensors. To the extent that such
            INVISIBLE IT Information is incorporated into any work product or
            deliverable developed by INVISIBLE IT hereunder, INVISIBLE IT hereby
            grants to ALIGN a perpetual, irrevocable, nonexclusive worldwide
            royalty-free right to use, execute, reproduce, display, perform,
            distribute, modify, and prepare derivative works (collectively,
            "Distribute") and have Distributed, to and by third parties, such
            INVISIBLE IT Information in conjunction with such work product or
            deliverable, and modified version thereof.

        (b) INVISIBLE IT retains the rights of ownership of any system
            administration utilities developed for ALIGN to be used or granted
            to any other INVISIBLE IT client or customer provided they: (i) do

            not divulge any Confidential Information of ALIGN; and (ii) will not
            be granted or issued or used by any direct competitor of ALIGN
            (listed on Schedule B hereto and includes any orthodontic or dental
            companies, as updated from time to time by mutual written consent)
            during the term of this Agreement. Such system administration
            utilities be considered INVISIBLE IT Information and licensed to
            ALIGN as set forth in Section 4(a).

        (c) If INVISIBLE IT agrees in writing as to a particular deliverable for
            WORK for ALIGN, then such WORK shall be deemed specially ordered and
            commissioned by ALIGN and may be incorporated in existing ALIGN
            works as a compilation or collective work. In that case, INVISIBLE
            IT agrees that all copyrights in the WORK shall be owned by ALIGN
            and the WORK shall be a "work made for hire" for copyright purposes
            (the "ASSIGNED WORK").

        (d) INVISIBLE IT hereby assigns to ALIGN, its successors and assigns,
            all rights, title and interest in and to the ASSIGNED WORK
            including, without limitation, the following:

            (i)   any U.S. copyrights that INVISIBLE IT may possess or acquire
                  in the ASSIGNED WORK and all copyrights and equivalent rights
                  in the ASSIGNED WORK throughout the world, including all
                  renewals and extensions of such rights that may be secured
                  under the laws now or hereafter in force and effect in the
                  United States of America or in any other country or countries;

            (ii)  all rights in and to any inventions, ideas, designs, concepts,
                  techniques, discoveries, or improvements, whether or not
                  patentable, embodied in the ASSIGNED WORK or developed in the
                  course of INVISIBLE IT's creation of the ASSIGNED WORK,
                  including but not limited to all trade secrets, utility and
                  design patent rights and equivalent rights in and to such
                  inventions and designs throughout the world regardless of
                  whether or not legal protection for the ASSIGNED WORK is
                  sought;

            (iii) any documents, magnetically or optically encoded media, or
                  other materials created by INVISIBLE IT as part of the
                  ASSIGNED WORK under this Agreement; and

            (iv)  the right to sue for infringements which may occur before the
                  date of this Agreement, and to collect and retain damages from
                  any such infringements from the ASSIGNED WORK.

        (e) At ALIGN's expense, INVISIBLE IT shall execute and deliver such
            instruments and take such other action as may be requested by ALIGN
            to perfect or protect ALIGN's rights in the ASSIGNED WORK and to
            carry out the assignments contemplated in subparagraph (b) of this
            section. In this regard, INVISIBLE IT agrees to cooperate with ALIGN
            in the filing and prosecution of any copyright or patent
            applications that ALIGN may elect to file on the ASSIGNED WORK or
            inventions and designs relating to the ASSIGNED WORK. ALIGN
            acknowledges that INVISIBLE IT has taken no action to assist in the
            registration of the copyrights or the ASSIGNED WORK and will do so
            only as and when requested by ALIGN.

        (a)    To the best of its knowledge, the ASSIGNED WORK as delivered to

               under written obligations to assign all rights in the ASSIGNED
               WORK to INVISIBLE IT;

        (d)    The services provided by INVISIBLE IT shall be performed in a
               professional manner and shall be of a high grade, nature, and
               quality; and

        (e)    To the best of its knowledge, the WORK and the ASSIGNED WORK
               performed by INVISIBLE IT under this Agreement will be in

6.3     Process.

        (a)    If any action shall be brought against ALIGN or INVISIBLE IT for
               a INVISIBLE IT Claim or a ALIGN Claim, respectively, the
               indemnified party shall promptly notify the indemnifying party in
               writing, specifying the nature of the action and the total
               monetary amount sought or other such relief as is sought therein.
               The indemnified party shall cooperate with the indemnifying party
               at the indemnifying party's expense in all reasonable respects in
               connection with the defense of any such action. The indemnifying
               party may upon written notice thereof to the indemnified party
               undertake to conduct all proceedings or negotiations in
               connection therewith, assume the defense thereof, and if it so
               undertakes, it shall also undertake all other required steps or
               proceedings to settle or defend any such action, including the
               employment of counsel which shall be satisfactory to the
               indemnified party, and payment of all expenses. The indemnified
               party shall have the right to employ separate counsel and
               participate in the defense thereof. The indemnifying party shall
               reimburse the indemnified party upon demand for any payments made
               or loss suffered by it at any time after the date hereof, based
               upon the judgment of any court of competent jurisdiction or
               pursuant to a bona fide compromise or settlement of claims,
               demands, or actions, in respect to any damages to which the
               foregoing relates.

        (b)    If any WORK OR ASSIGNED WORK furnished hereunder is in any action
               held to constitute an infringement and its use is enjoined,
               INVISIBLE IT shall immediately and at its expense:

               (i)   procure for ALIGN the right to continue use, sale, and
                     marketing of the WORK or the ASSIGNED WORK; or

               (ii)  replace or modify the WORK or the ASSIGNED WORK with a
                     version of the WORK or the ASSIGNED WORK that is
                     non-infringing.

        If (i) or (ii) are not available to INVISIBLE IT, INVISIBLE IT shall
        refund to ALIGN all amounts paid to INVISIBLE IT by ALIGN hereunder for
        the particular WORK and/or for the particular ASSIGNED WORK.

6.4     Survival.

        The foregoing indemnity provision of this Section 6 shall survive any
        termination or expiration of this Agreement for a period of three (3)
        years.

7.      Termination.

        (a)    This Agreement shall commence as of the Effective Date and shall
               remain in force in perpetuity unless earlier terminated as set
               forth in Section 7(b).

        (b)    Termination for Cause. Either party may suspend performance
               and/or terminate (A) this Agreement or (B) a particular Schedule
               under this Agreement immediately upon written notice at any time
               if:

               (i)   The other party is in material breach of any material
                     warranty, term, condition or covenant of this Agreement,
                     other than those contained in Section 3, and fails to cure
                     that breach within thirty (30) days after written notice
                     thereof; or

               (ii)  The other party is in material breach of Section 3.

        (c)    ALIGN shall have the right to cancel any Schedule pursuant to the
               terms of such Schedule. Such terms may include cancellation fees,
               as the parties may agree, for a termination without cause. In the
               event ALIGN cancels a Schedule, ALIGN will provide INVISIBLE IT
               written notice of such cancellation. Upon receipt of such notice,
               INVISIBLE IT will discontinue all work thereunder. Except in
               cases of cancellation for cause as specified in Section 7(b) of
               this Agreement, ALIGN will pay for all work performed by
               INVISIBLE IT up until the date of receipt of the cancellation
               notice and cancellation fees, if any, specified in such Schedule.
               In the event of cancellation of a Schedule, upon request by
               ALIGN, INVISIBLE IT agrees to turn over to ALIGN all Assigned
               Work with respect to such Schedule within ten (10) days of
               payment of all outstanding amounts.

 9.     Arbitration.

        (a)    Except for injunctive relief sought pursuant to Section 3(c), all
               disputes arising out of or in connection with this Agreement,
               including any questions regarding its existence, validity, breach
               or termination, shall be finally settled by binding arbitration
               under the CPR Non-Administered Arbitration Rules ("Rules") of the
               CPR Institute for Dispute Resolution ("CPR") by a sole arbitrator
               in accordance with said Rules. The arbitration shall be governed
               by the United States Arbitration Act, 9 U.S.C. Section 1-16.

        (b)    Both parties shall agree on a sole arbitrator within 30 days.
               Should the two parties fail, within the above time-limit, to
               reach agreement on the arbitrator, the arbitrator shall be
               appointed by CPR under the applicable Rules ("Appointing
               Authority"). If there are two or more defendants, any nomination
               of an arbitrator by or on behalf of such defendants must be by
               joint agreement between them. If such defendants fail, within the
               time-limit fixed by the Appointing Authority, to agree on such
               joint nomination, the proceedings against each of them must be
               separated. The arbitrator must have sufficient experience in the
               software industry and in international business transactions.

        (c)    Notwithstanding the Rules, the parties (i) shall submit their
               dispute to the arbitrator within 2 months following their
               decision that they could not resolve their dispute, (ii) each
               party shall have no more than 2 days to present its case and
               (iii) the arbitrator shall be instructed to render its decision
               within 30 days following the conclusion of each party's
               presentation.

        (d)    The arbitrator shall specify the basis for its decision. The
               arbitrator shall not award any punitive damages. The decision of
               the arbitrator shall be considered as a final and binding
               resolution of the

               dispute,  shall not be  subject to appeal and may be entered as a
               judgment in any court of competent jurisdiction.

        (e)    The seat of arbitration shall be Santa Clara, California. The
               procedural law of this place shall apply where the Rules are
               silent, however no jury trial shall be allowed in the arbitration
               proceedings and discovery shall be limited as set forth in the
               Rules.

        (f)    The whole arbitration procedure shall be executed pursuant to a
               strict non disclosure agreement signed by the parties and the
               arbitrators agreeing to conduct such proceedings and maintaining
               in confidence all confidential information or trade secrets
               disclosed or produced in the course thereof. All press releases
               or public statements regarding the status of such proceedings
               shall be prepared jointly and only by the parties.

10.     Miscellaneous.

        (a)    INVISIBLE IT is an independent contractor for ALIGN, and nothing
               in this Agreement shall be construed as creating an
               employer-employee relationship, a partnership, or a joint venture
               between the parties.

        (b)    In the event taxes are required to be withheld on payments made
               hereunder by any U.S. (state or federal) or foreign government,
               ALIGN may deduct such taxes from the amount owed INVISIBLE IT and
               pay them to the appropriate taxing authority. ALIGN shall in turn
               promptly secure and deliver to INVISIBLE IT an official receipt
               for any taxes withheld. ALIGN will use reasonable efforts to
               minimize such taxes to the extent permissible under applicable
               law.

        (c)    This Agreement shall be construed and controlled by the laws of
               the State of California, Northern District. The federal and state
               courts within the State of California, Northern District, shall
               have exclusive jurisdiction to adjudicate any dispute arising
               with this Agreement and INVISIBLE IT hereby consents to such
               jurisdiction. In any action or suit to enforce any right or
               remedy under this Agreement or to interpret any provision of this
               Agreement, the prevailing party shall be entitled to recover its
               costs, including reasonable attorneys' fees.

        (d)    This Agreement does not constitute an offer by ALIGN and it shall
               not be effective until signed by both parties. This Agreement
               constitutes the entire agreement between the parties with respect
               to the WORK and all other subject matter hereof and merges all
               prior and contemporaneous communications. It shall not be
               modified except by a written agreement dated subsequent to the
               date of this Agreement and signed on behalf of INVISIBLE IT and
               ALIGN by their respective duly authorized representatives. Any
               Schedules attached to this Agreement must be signed on behalf of
               INVISIBLE IT and ALIGN by their respective duly authorized
               representatives. Schedules shall not act to amend this Agreement.
               The terms and conditions of this Agreement shall take precedence
               over any conflicting terms and conditions in any Schedule;
               provided, however, to the extent the terms and conditions of a
               particular Schedule so conflict with the terms and conditions of
               this Agreement, the terms and conditions of the Schedule shall
               take precedence only with respect to the Services under that
               Schedule.

        (e)    This Agreement may be assigned by ALIGN or by INVISIBLE IT with
               mutual prior written approval. Except as otherwise provided, this
               Agreement shall be binding upon and inure to the benefit of the
               parties' successors and lawful assigns.

        (f)    ALIGN and INVISIBLE IT mutually agree that they will use
               reasonable commercial efforts to not recruit and hire employees
               of the other party, assigned to work under this Agreement during
               their assignment under the applicable Schedule of this Agreement.
               Should either party solicit and hire an employee form the other,
               The hiring party shall pay a one-time, liquidated damage fee
               equal to fifty-five percent (55%) of such employee's offered
               annual salary. Each party agrees to pay any such employment fee
               within ten (10) days following the employee's commencement of
               employment.

        (g)    A service charge of one percent (1%) per month or the highest
               rate allowed by law shall apply to all overdue amounts owed to
               Supplier. ALIGN acknowledges that unpaid invoices may result in
               the interruption of services provided.

                    SETTLEMENT AGREEMENT AND MUTUAL RELEASE

     This Settlement Agreement and Mutual Release ("Agreement") is made and
entered into as of February 6, 2003, by and among GW Com, Inc., now known as
Byair, Inc. ("GW"), Intelecady, Inc. ("Intelecady"), James S. Lindsey
("Lindsey"), and Align Technology, Inc. ("Align").

                                  I. RECITALS

     1. On May 1, 2002, GW filed a complaint (the "Complaint") against Lindsey
and Align thereby initiating an action (the "Action") in the Santa Clara County
Superior Court numbered Case No. CV 807489.

     2. On August 1, 2002, Lindsey filed a cross-complaint (the
"Cross-Complaint") in the Action against GW and Intelecady.

     3. The Action arose out of a dispute between the parties relating to a
Lease (the "Lease") dated October 4, 1999 between Lindsey as Lessor and Golfpro
International, Inc. ("Golfpro") as Lessee for approximately 50,000 square feet
of space at 851 Martin Avenue, Santa Clara, California (the "Leased Premises");
a sublease (the "Sublease") dated April 17, 2000 between Golfpro as Sublessor
and GW as Sublessee for the Leased Premises; a Consent to Sublease (the
"Consent") dated on or about April 20, 2000 by and among Golfpro, GW, and
Lindsey; a Sub-Sublease (the "Sub-Sublease") dated July 27, 2000 between GW as
Sub-Sublessor and Align as Sub-Sublessee for a portion of the Leased Premises; a
proposed amendment (the "November Amendment") to the Sub-Sublease dated November
1, 2000 between GW and Align for an additional portion of the Leased Premises; a
proposed amendment (the "February Amendment") to the Sub-Sublease dated February
2001 between GW and Align for an additional portion of the Leased Premises. On
September 18, 2001, the United States Bankruptcy Court for the Northern District
of California approved Golfpro's Chapter 11 Plan of Reorganization including
Golfpro's assignment of its rights under the Lease, Sublease, and Consent to
Intelecady and Intelecady's assumption of the rights and obligations under such
agreements (the "Golfpro Assignment").

     4. GW holds in an account the sum of $188,000.00 earmarked for Align and
representing a cash security deposit paid by Align to GW pursuant to the
Sub-Sublease (the "Cash Security Deposit") which Align asserts must be returned
to Align pursuant to Civil Code section 1950.7.

     5. Lindsey has asserted claims against GW and Intelecady of approximately
S94,000.00 in connection with alterations to the Leased Premises that he asserts
were undertaken without his prior written consent.

                                        1

<PAGE>

     6. Align and Lindsey contend that each has incurred attorneys' fees and
costs in excess of $125,000 in connection with the Action.

     7. Align filed a motion under Code of Civil Procedure section 1030 in the
Action to secure recovery of the attorneys' fees and costs incurred by Align in
connection with the Action and Lindsey contends that he was in the process of
preparing a similar motion under Code of Civil Procedure section 1030 at the
time of this Agreement.

     8. The parties desire to resolve all claims and disputes related to the
Action, the Leased Premises, the Lease (except as set forth herein), the
Sublease, the Consent, the Sub-Sublease, the November Amendment, and the
February Amendment.

                                  II. AGREEMENT

     For good and valuable consideration, the parties agree as follows:

     1. The Recitals are incorporated herein and made a part of this Agreement.

     2. Intelecady hereby represents that Golfpro has assigned to it all of
Golfpro's rights under the Lease and the Sublease and that Intelecady is the
exclusive owner of any and all claims that Golfpro ever had under or relating to
the Lease, the Leased Premises, the Sublease, the Consent, the Sub-Sublease, the
November Amendment, or the February Amendment and that its releases herein are
effective to release Golfpro's claims to the same extent as they release
Intelecady's claims.

     3. Intelecady and GW hereby represent that GW has assigned to Intelecady
all of GW's rights under the Lease and the Sublease and that Intelecady is the
exclusive owner of any and all claims that GW ever had under or relating to the
Lease, the Leased Premises, the Sublease, the Consent, the Sub-Sublease, the
November Amendment, or the February Amendment and that Intelecady's releases
herein are effective to release GW's claims to the same extent as they release
Intelecady's claims.

     4. GW hereby represents that it is now known as Byair, Inc., and GW has the
authority to bind Byair, Inc. to the terms of this Agreement.

     5. No later than 5:00 p.m., on Monday, February 10, 2003, GW shall pay to
Align the sum of $188,000 by wire transfer to Align or in the form of Cashier's
Check delivered to the attention of Roger George at Align's offices at 821
Martin Avenue, Santa Clara, California, as and for a return of the Cash Security
Deposit.

     6. Concurrent with the execution of this Agreement, the parties hereto will
execute and cause to be filed a Request for Dismissal of the action in its
entirely with prejudice in the form attached hereto as Exhibit A.

Golfpro Assignment, the Leased Premises, the Lease, the Sublease, the Consent,
the Sub-Sublease, the November Amendment, and the February Amendment (the "GW
Released Matters").

     8. Except as to the obligations created by this Agreement, Intelecady for
itself and for its current and former employees, members, partners,
stockholders, directors, officers, parents, subsidiaries, predecessors,
affiliates, successors, assigns, agents and attorneys, hereby does absolutely
discharge and release Lindsey and his current and former employees, members,

predecessors, affiliates, successors, assigns, agents and attorneys, and Align
and its current and former employees, members, partners, stockholders,
directors, officers, parents, subsidiaries, predecessors, affiliates,
successors, assigns, agents and attorneys, from any and all liabilities, causes
of action and claims which do or may exist, whether known or unknown, suspected

     9. Except as to the obligations created by this Agreement and except as

former employees, members, partners, stockholders, directors, officers, parents,
subsidiaries, predecessors, affiliates, successors, assigns, agents and
attorneys, hereby does absolutely discharge and release GW and its current and
former employees, members, partners, stockholders, directors, officers, parents,
subsidiaries, predecessors, affiliates, successors, assigns, agents and
attorneys, and Intelecady and its current and former employees, members,
partners, stockholders, directors, officers, parents, subsidiaries,

                                        3

<PAGE>

assigns, agents and attorneys, and Intelecady and its current and former
employees, members, partners, stockholders, directors, officers, parents,
subsidiaries, predecessors, affiliates, successors, assigns, agents and
attorneys, from any and all liabilities, causes of action and claims which do or

limited to claims arising out of or in any way related to the Action, the
Golfpro Assignment, the Leased Premises, the Lease, the Sublease, the Consent,
the Sub-Sublease, the November Amendment, and the February Amendment (the "Align
Released Matters").

     11. Notwithstanding anything to the contrary in this Agreement, Lindsey is
not by this Agreement releasing his claims against Intelecady or GW for breach
of the Lease, the Sublease, or the Consent. Lindsey is hereby, however,
releasing Intelecady and GW from any claim that either or both are responsible
for the costs of removing from the Leased Premises alterations made to that
portion of the Leased Premises subject to the Align Sub-Sublease, including the
demising wall between such premises and the remaining Leased Premises, and
thereafter restoring such premises. Lindsey, GW, and Intelecady are concurrently
entering into another agreement entitled the "Lease Termination Agreement"
regarding the Lease, the Sublease, and the Consent and containing releases
thereto.

     12. Each of the parties to this Agreement warrants that it has not
assigned, conveyed, granted, transferred, or otherwise disposed of any of the
claims released by such party pursuant to this Agreement.

     13. Each party to this Agreement covenants and agrees that neither it nor
its current and former employees, members, partners, stockholders, directors,
officers, parents, subsidiaries, predecessors, affiliates, successors, assigns,
agents and attorneys will hereafter commence, maintain or prosecute any action
at law or otherwise, or assert any claim or charge against any other party or
such other partys' current and former employees, members, partners,
stockholders, directors, officers, parents, subsidiaries, predecessors,
affiliates, successors, assigns, agents and attorneys for damages or loss of any
kind or amount arising out of each party's Released Matters.

     14. Each party to this Agreement acknowledges that it may hereafter
discover facts different from or in addition to those now known or believed to
be true regarding the subject matter of the above and agree that this Agreement
shall remain in full force and effect, notwithstanding the existence of any such
different or additional facts. Each party to this Agreement acknowledges that it
has been informed by its counsel of the provisions of Section 1542 of the Civil
Code, and each party hereby waives any and all rights which it have or may have
under the provisions of Section 1542 of the Civil Code as now worded and as
hereafter amended, which section presently reads as follows:

     "A GENERAL RELEASE DOES NOT EXTEND TO ANY CLAIMS WHICH THE CREDITOR DOES
     NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE
     RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT
     WITH THE DEBTOR."

                                        4

<PAGE>

Each party waives and relinquishes any right or benefit which it has or may have
under any similar provision of the statutory or nonstatutory law of any
jurisdiction. Each party acknowledges that it is aware that it or its respective
attorneys and/or agents may hereafter discover facts in addition to or different
from those which it now knows or believes to exist with respect to the subject
matter of this Agreement, but that it is its intention hereby to fully, finally
and forever to settle and release all of its claims, disputes and differences,
known or unknown, suspected or unsuspected, which now exist or may exist
hereafter against each other party and such other party's current and former
employees, members, partners, stockholders, directors, officers, successors,
assigns, agents and attorneys, relating to the Released Matters, except as
provided for herein. This Release shall be and remain in effect as a full and
complete release as to the Released Matters notwithstanding the discovery or
existence of any such additional or different facts.

     15. Each party to this Agreement shall execute whatever documents may be
necessary and appropriate to carry out the intent and purpose of this Agreement.

     16. Nothing in this Agreement shall affect any party's right to conduct or
respond to discovery as to any matter in connection with any lawsuit or
proceeding.

     17. This Agreement is for the sole purpose of settling the Released Matters
and it is expressly understood and agreed that this Agreement does not
constitute or evidence any admission of any party of any liability or the truth
of any of the Released Matters. Accordingly, nothing in this Agreement shall be
construed as an admission of liability or wrongdoing on the part of any of the
parties hereto.

     18. This Agreement shall be binding upon and shall inure to the benefit of
the parties and their respective representatives, heirs, predecessors,
affiliates, successors and assigns.

     19. In the event that any of the terms of this Agreement are found to be
unenforceable by a court of competent jurisdiction, the remainder of this
Agreement shall not be affected thereby and shall remain in full force and
effect.

     20. This Agreement may be executed in any number of separate counterparts,
all of which, when taken together, shall constitute one and the same instrument,
admissible into evidence, notwithstanding the fact that all parties did not sign
the same counterpart. Delivery of an executed counterpart of this Agreement by
telefacsimile shall be equally as effective as delivery of a manually executed
counterpart hereof. Any party delivering an executed counterpart of this
Agreement by telefacsimile shall also deliver a manually executed counterpart
hereof, but the failure to deliver a manually executed counterpart hereof shall
not affect the validity, enforceability, and binding effect of this Agreement.

     21. The parties acknowledge that they have entered into this Agreement in
reliance on their own independent investigation and analysis of the facts
underlying the subject matter of the Agreement, and that, in executing this
Agreement, no representations, warranties or promises of any kind have been made
directly or indirectly to induce them to execute this Agreement other

                                        5

<PAGE>

than those that are expressly set forth herein, and that they have not relied on
any representations, warranties or promises of any kind other than those that
are expressly set forth herein.

     22. The parties acknowledge to each other that each was advised and
represented by independent legal counsel of each party's own choice throughout
all of the negotiations which preceded the execution of this Agreement and that
each such party has executed this Agreement after being so advised or receiving
such advice. The parties acknowledge that each party has executed this Agreement
without reliance upon any promise or representation of any person or persons
acting for or on behalf of the other, except as expressly set forth in this
Agreement. Each party further acknowledges that such party and such party's
counsel has had an adequate opportunity to make whatever investigation or
inquiry it may deem necessary or desirable in connection with the subject matter
of this Agreement prior to the execution of this Agreement. Each party and such
