                           (A)      prior to granting any rights to any Person
                                    pursuant to this Section 2.2(ii), Leitch
                                    shall provide written notice to Path 1
                                    identifying the Person to whom Leitch
                                    proposes to grant such rights (the "PROPOSED
                                    LICENSEE");

                           (B)      Path 1 may, within thirty (30) Calendar Days
                                    following the receipt of such notice, notify
                                    Leitch in writing that Leitch may not grant
                                    any rights to the Proposed Licensee,
                                    provided that Path 1 may only provide such
                                    notice to Leitch if, in Path 1's reasonable
                                    determination, there is a material and
                                    foreseeable likelihood that the Proposed
                                    Licensee's exercise of such rights shall
                                    have a material adverse effect on Path 1's
                                    commercial activities relating to the
                                    Non-Exclusive Market Use;

                           (C)      if Path 1 provides the notice referred to in
                                    Section 2.2(ii)(B) within thirty (30)
                                    Calendar Days following the receipt by Path
                                    1 of the notice provided by Leitch pursuant
                                    to Section 2.2(ii)(A), Leitch shall not be
                                    entitled to grant the rights to such Person
                                    pursuant to this Section 2.2(ii); and

                           (D)      if Path 1 does not provide the notice
                                    referred to in Section 2.2(ii)(B) within
                                    thirty (30) Calendar Days following the
                                    receipt by Path 1 of the notice provided by
                                    Leitch pursuant to Section 2.2(ii)(A),
                                    Leitch shall be entitled to grant the rights
                                    to such Person pursuant to this Section
                                    2.2(ii).

                  (iii)    During the period commencing on the first Calendar
                           Day following the expiry of the Exclusive Term and
                           continuing for the duration of the Term, Leitch shall
                           have the non-exclusive, worldwide right to make, have
                           made, sell, offer for sale, Sublicense, support,
                           maintain and otherwise exploit the TrueCircuit
                           Products in connection with commercial activities
                           directed to the Exclusive Market Use.

                  (iv)     During the Term, subject to any exclusive rights
                           granted by Path 1 in accordance with Section 2.4 and
                           the limitations thereon set forth in Section 2.4,
                           Leitch shall have the non-exclusive, worldwide right
                           to make, have made, sell, offer for sale, Sublicense,
                           support, maintain and otherwise exploit the
                           TrueCircuit Products in connection with commercial
                           activities relating to the Non-Exclusive Market Use.
                           The terms and conditions of this Agreement shall
                           apply to the exercise by Leitch of this right;
                           provided, however, the Parties agree to negotiate in
                           good faith such different or additional terms and
                           conditions governing the exercise by Leitch of this
                           right as may be commercially reasonable and
                           consistent with industry standard and which shall be
                           at least as favourable in all respects as the terms
                           and conditions extended to any other customer or
                           licensee of Path 1.

                  (v)      Leitch shall have no right to grant sublicenses under
                           this Agreement other than the rights specifically set
                           forth in Section 2.2 (ii) and the right to grant
                           Sublicenses specifically set forth in this Section
                           2.2.

         Leitch shall design and manufacture TrueCircuit Products in accordance
         with any reasonable quality and performance criteria provided by Path 1

         basis to Path 1 a reasonable number of samples of TrueCircuit Products
         for testing, together with instruction and service manuals. In the
         event that Path 1 shall provide Leitch with written notice that any
         TrueCircuit Product offered for sale by Leitch does not comply with
         such reasonable quality and performance criteria, Leitch shall, within
         one hundred twenty (120) days of receipt of such notice from Path 1,
         either a) remedy the noncompliance or b) suspend the sale of the same.
         In addition, Leitch shall include in its agreements with its Proposed

         2.4      RIGHT OF FIRST OFFER IN RESPECT OF PATH 1 INTELLECTUAL
                  PROPERTY

         Path 1 shall have the right to grant to an Arm's Length Licensee the
         exclusive right to use the Path 1 Intellectual Property to manufacture
         products and to sell such products in connection with commercial
         activities relating to any Non-Exclusive Market Use, provided that Path
         1 shall not grant any such exclusive right without first providing
         Leitch with the option to acquire that exclusive right in accordance
         with the following procedure:

                  (i)      Path 1 shall provide written notice to Leitch
                           specifying the major terms and conditions pursuant to
                           which Path 1 proposes to grant to Leitch the
                           exclusive right to use the Path 1 Intellectual
                           Property to manufacture products and to sell such
                           products in connection with commercial activities
                           relating to a Non-Exclusive Market Use (the "OFFER").
                           The terms and conditions proposed by Path 1 in the
                           Offer shall be reasonable, consistent with this
                           Agreement and consistent with industry standards;

                  (ii)     Leitch shall provide written notice to Path 1
                           indicating whether it rejects the Offer or whether it
                           wishes to negotiate the terms of the Offer with Path
                           1 within fourteen (14) Calendar Days of the date
                           Leitch receives such notice. If Leitch does not
                           respond to Path 1 within such fourteen (14) Calendar
                           Day period, Leitch shall be deemed to have rejected
                           the Offer and Path 1 shall be governed by the
                           provisions of Section 2.4(vi);

                  (iii)    if Leitch provides written notice to Path 1 that it
                           wishes to negotiate the terms of the Offer with Path
                           1 in accordance with Section 2.4(ii), then, for a
                           period of up to thirty (30) Calendar Days following
                           the date upon which Leitch received the Offer from
                           Path 1, Leitch and Path 1 shall negotiate exclusively
                           the terms upon which Leitch shall be exclusively
                           entitled to use the Path 1 Intellectual Property to
                           manufacture products and to sell

                           such products in connection with commercial
                           activities relating to such Non-Exclusive Market
                           Use based upon the terms and conditions set out in
                           the Offer. The Parties may extend this thirty (30)
                           Calendar Day exclusive negotiating period upon
                           mutual written agreement;

                  (iv)     if Leitch and Path 1 agree in writing to the terms
                           and conditions pursuant to which Leitch shall be
                           exclusively entitled to use the Path 1 Intellectual
                           Property to manufacture products and to sell such
                           products in connection with commercial activities
                           relating to such Non-Exclusive Market Use, then Path
                           1 shall grant such exclusive rights to Leitch;

                  (v)      if Leitch and Path 1 fail to agree in writing to the
                           terms and conditions pursuant to which Leitch shall
                           be exclusively entitled to use the Path 1
                           Intellectual Property to manufacture products and to
                           sell such products in connection with commercial
                           activities relating to such Non-Exclusive Market Use
                           or if Leitch notifies Path 1 in writing that it
                           rejects the Offer, then Leitch shall be deemed to
                           have rejected the Offer;

                  (vi)     if Leitch is deemed to have rejected the Offer
                           pursuant to Section 2.4(ii) or Section 2.4(v), then
                           Path 1 may grant the exclusive right to use the Path
                           1 Intellectual Property to manufacture products and
                           to sell such products in connection with commercial
                           activities relating to such Non-Exclusive Market Use
                           to any Arm's Length Licensee upon terms and
                           conditions which, taken as a whole, are not
                           materially more favourable than those offered to
                           Leitch, provided that Path 1 may not grant such
                           rights to any such Arm's Length Licensee later than
                           one hundred and eighty (180) Calendar Days after the
                           date that Leitch is deemed to have rejected the Offer
                           without Leitch's prior written consent. If Path 1

                           more favourable than those offered to Leitch, Path 1
                           must first offer such more favourable terms to Leitch
                           on an exclusive basis, and the Parties shall attempt

                           Arm's Length Licensee the exclusive right to use the

                           that, subject to Section 2.4(viii), it shall not
                           knowingly sell any TrueCircuit Products within the

         2.5      NETWORK OPERATING SYSTEM

         Path 1 shall develop a Network Operating System and shall enter into a

         a license to use, and sell and distribute sublicenses to use, the

         exploitation by Leitch of TrueCircuit Products in accordance with the
         terms of this Agreement. The Network Operating System shall be supplied
         in object code format only; however, Path 1 shall enter into a separate
         source code escrow agreement with Leitch and an escrow agent acceptable
         to both Leitch and Path 1. Such license agreement shall provide that
         Leitch shall pay to Path 1 a license fee in respect of the Network
         Operating System to be mutually agreed to by the Parties, which such
         license fee shall:

                  (i)      be consistent with similar license fees charged for
                           the right to use and exploit similar Technology in
                           the market segment in respect of which Leitch has the
                           right to use and exploit the Network Operating System
                           and be commercially reasonable based upon the value
                           of the market segment in respect of which Leitch has
                           the right to use and exploit the Network Operating
                           System, taking into account the market's size,
                           potential, competitive pressures and other
                           characteristics which affect its value;

                  (ii)     be at least as favourable to Leitch as the most
                           favourable license fee paid by any Person to Path 1
                           for similar license rights to use and exploit similar
                           Technology in a market segment similar to the market
                           segment in respect of which Leitch has the right to
                           use and exploit the Network Operating System; and

                  (iii)    subject to applicable competition or anti-trust laws,
                           be in an amount which, based on the characteristics
                           of the market in respect of which Leitch has the
                           right to use and exploit the Network Operating
                           System, enables Leitch to charge a price to its
                           customers for the Network Operating System which
                           includes a margin of no less than [****].

         In consideration of the rights granted by Path 1 to Leitch pursuant to
         Article 2, commencing on the first Business Day following the expiry of
         the Royalty-Free Period and continuing in respect of each consecutive
         three (3) month period thereafter, Leitch shall pay Path 1 a royalty in
         respect of each individual TrueCircuit Product sold by Leitch or any
         Leitch sublicensee for which Leitch or such Leitch sublicensee has
         received full payment during such three-month period which is equal to
         the lesser of:

                  3.1.1    [****]; and

                  3.1.2    [****] of the Net TrueCircuit Product
                           Revenue for such TrueCircuit Product.

         3.2      PAYMENT PROCESS AND REPORTING

         Within thirty (30) Calendar Days after the end of each three-month
         period in respect of which a royalty payment is due, Leitch shall
         provide to Path 1 a written report containing all relevant information
         upon which Leitch's calculation of the royalty due and payable is
         based. Within ten (10) Business Days after delivery of the report, Path
         1 shall render to Leitch an invoice indicating the amount of the
         royalty due for such period. All such royalty payments shall be due and
         payable by Leitch within thirty (30) Calendar Days following the
         receipt by Leitch of such invoice.

         3.3      TAXES

         Each Party shall be responsible for the payment of those taxes, duties,
         and levies levied on that Party from time to time in relation to such
         Party's performance pursuant to this Agreement. Where one Party is
         required to collect and remit taxes payable by the other Party, that
         Party shall so collect and remit such taxes. Without limiting the
         generality of the foregoing, Leitch shall be entitled to withhold from
         all fees payable to Path 1 hereunder all applicable withholding taxes
         and to remit same to all applicable taxing authorities as required by
         law.

         3.4      AUDIT

         Leitch will keep complete and accurate books and records containing
         information reasonably necessary for the purpose of determining the
         amount of royalties payable to Path 1 hereunder. At the request of Path
         1, such books and supporting data will be made available, upon
         reasonable notice during the Term of this Agreement and for a period of
         two (2) years after its termination or expiration, for inspection by an
         independent third party auditor selected by the Party requesting the
         audit and reasonably acceptable to Leitch. In the event any such audit
         reveals an error in the books and records relating to the royalties
         payable to Path 1, the overpayment or deficiency will be paid by the
         appropriate Party within thirty (30) calendar days after completion of
         the audit. The cost of such audit will be paid by the Party requesting
         the audit, provided that if such audit reveals an error adverse to the
         auditing Party in excess of ten percent (10%), Leitch will pay, in
         addition to the deficiency, the reasonable, documented fees and
         expenses of such auditor.

                  6.2.3    The Parties agree to follow the process set out in
                           this Section 6.2.3 in order to determine the minimum
                           Aggregate Annual Fees requirement applicable to the
                           sixth (6th) and each subsequent Exclusive Year. No
                           later than ninety (90) Calendar Days prior to the end
                           of the then-current Exclusive Year, the Parties shall
                           meet and negotiate in good faith the Aggregate Annual

                           Exclusive Year. The Parties agree that each such
                           Aggregate Annual Fees requirement shall be no less
                           than the Aggregate Annual Fees requirement applicable
                           to the preceding Exclusive Year and no greater than
                           one and one half (1.5) times the Aggregate Annual
                           Fees requirement applicable to the preceding
                           Exclusive Year.

                  6.2.4    Path 1 may reduce the Aggregate Annual Fees
                           requirement in any Exclusive Year or extend the
                           period of time in respect of which Leitch must

                           the Exclusive Year in the event that the actual
                           market conditions during such Exclusive Year are less
                           favourable than the forecasted market conditions for

                           performance (including through recourse to the

                           shall be considered resolved until both Parties have
                           agreed to the resolution in writing. The designated
                           Committee members shall mutually agree on the methods
                           by which they attempt to resolve any dispute such as,

                           be shared equally by the Parties.

                  8.4.2    In the event that each Party's designated Committee
                           members cannot resolve a dispute under the Agreement
                           as specified in Section 8.4.1 above, then each
                           Party's respective Presidents (or an equivalent or

                           Calendar Days of their initial conference. No dispute
                           shall be considered resolved until both Parties have
                           agreed to the resolution in writing. The respective
                           Presidents (or equivalents) shall mutually agree on
                           the methods by which they attempt to resolve any
                           dispute such as, for example, telephone and/or video
                           conferences, e-mail and fax communications, and/or
                           face to face meetings. The costs under this
                           Subsection 8.4.2 shall be shared equally by the
                           Parties.

                  8.4.3    In the event that each Party's respective Presidents
                           (or equivalents) cannot resolve a dispute under the
                           Agreement as specified in Subsection 8.4.2 above,
                           then the Parties shall resolve such dispute by
                           arbitration administered by the American Arbitration
                           Association under its Commercial Arbitration Rules,

         or cause to be done, made, executed or delivered, all such further
         acts, documents and things as the other Party hereto may reasonably
         require from time to time for the purpose of giving effect to this
         Agreement and shall use commercially reasonable efforts and take all
         such steps as may be reasonably within its power to implement to their
         full extent the provisions of this Agreement.

         9.6      SEVERABILITY

         Any provision of this Agreement which is invalid or unenforceable in
         any jurisdiction shall, as to that jurisdiction, be ineffective to the
         extent of such invalidity or unenforceability and shall be severed from
         the balance of this Agreement, all without affecting the remaining
         provisions of this Agreement or affecting the validity or
         enforceability of such provision in any other jurisdiction and
         appropriate amendments shall be made to this Agreement to put the Party
         who is disadvantaged by such invalidity or unenforceability in the same
         financial position as if no provision hereof were invalid or
         unenforceable. In the event that any portion of this Agreement shall
         have been so determined to be or become invalid or unenforceable (the
         "Offending Portion"), the Parties shall negotiate in good faith such
         changes to this Agreement as shall best preserve for the Parties the
         benefits and obligations of such Offending Portion.

         another Party. The waiver by a Party of any default, breach or
         non-compliance under this Agreement shall not operate as a waiver of

                     SETTLEMENT AGREEMENT AND MUTUAL RELEASE

         THIS SETTLEMENT AGREEMENT AND MUTUAL RELEASE ("Agreement") is made and
entered into on April 11, 2000 among PATH 1 NETWORK TECHNOLOGIES INC., a
Delaware corporation ("Path 1"), DOUGLAS A. PALMER, RONALD D. FELLMAN, RODERICK
ADAMS, PAUL ROBINSON, MICHAEL BERNS, JAMES BERNS, RONA BERNS and BERNS & BERNS,
who agree as follows:

         1.       RECITALS. This Agreement is made with reference to the
following facts:

                  1.1      On September 20, 1999, Path 1 filed, and there is now
pending, a lawsuit against Michael Berns, James Berns, Rona Berns, Berns & Berns
(collectively, the "Berns Parties") and Franklin Felber in the San Diego County
Superior Court, Case No. GIC 735665 (the "Lawsuit"). The Lawsuit relates in part
to 1,655,000 shares of Path 1 Class A Common Stock issued to James Berns and
Rona Berns (the "Berns Path 1 Shares"). Rona Berns has specially appeared to
contest personal jurisdiction over her in the Lawsuit.

                  1.2      On November 9, 1999, Michael Berns and James Berns,
and Franklin Felber, filed, and there is now pending, a lawsuit against Path 1
in the Delaware Court of Chancery in and for New Castle County (Civil Action No.
17562) for indemnification and advancement of defense expenses with respect to
the Lawsuit (the "Delaware Action").

                  1.3      James Berns and Rona Berns are renegotiating an
agreement to sell all of their Berns Path 1 Shares to Leitch Technology

listed in Sections 2.1 and 2.2 below have been satisfied or waived. All actions
to be taken and all documents to be executed and delivered by all parties at or

such documents executed or delivered until all have been taken, executed and

does not occur on or before April 11, 2000 or such later date as Path 1 and the
Berns Parties may agree to in writing, then at any time thereafter, but before

                  5.2      The foregoing mutual release constitutes a general
release and shall extend to all claims of every nature and kind whatsoever,
known or unknown, suspected or unsuspected, including, but not limited to, any
claims based on contract, tort, statute, breach of duty, bad faith, negligence,
or any other theory of liability.

                  5.3      The Path 1 Parties and the Berns Parties explicitly
waive any and all rights which they may have under the provisions of California
Civil Code section 1542, which section reads as follows:

                  A general release does not extend to 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.

                  5.4      The foregoing mutual release shall inure to the
benefit of and be binding upon the parties and their respective predecessors,
successors, assigns, heirs, executors,

                                       5

administrators, spouses, employees, agents, servants, partners, shareholders,
directors, officers, managers, parents and subsidiaries, affiliates, guarantors,
representatives, insurers and attorneys.

                  5.5      Franklin Felber is not a party to, nor included
within or benefitted by, the foregoing mutual release in this Section 5. Any
claims for indemnity or contribution that may be brought by any of the parties
to this Agreement (other than Path 1) as a result of claims brought (or that may
be brought) by Franklin Felber are not released in this Section 5.

         6.       COVENANT NOT TO SUE. Effective as of the Closing, the Path 1
Parties, on the one hand, and the Berns Parties, on the other hand, each agrees
to forever refrain and forebear from commencing, voluntarily assisting,
instituting or prosecuting any litigation, action, arbitration, administrative
or other proceeding of any kind against the other directly or indirectly arising
out of, resulting from or relating in any way to the subject matter of the
release contained in Section 5.

         7.       EXCLUSIONS. Notwithstanding the provisions of Sections 5 and
6, the releases and covenants not to sue contained therein shall not apply to
(a) the rights and obligations of the parties under this Agreement or any of the
documents delivered in connection with this Agreement, (b) claims by the parties
to this Agreement (other than Path 1) for indemnity or contribution arising out
of any action, claim or proceeding of any kind brought (or that may be brought)
by Franklin Felber, and (c) the rights and claims, if any, of the parties to
this Agreement against Jyra Research Inc. and/or Jyra Research Limited
(collectively, "Jyra") or of Jyra against the parties to this Agreement. This
Section 7 does not affect the indemnity provisions of Section 3 above.

         8.       NO LIABILITY ADMITTED. Each of the parties explicitly
acknowledges and agrees that this Agreement represents a settlement of disputed
claims and that by entering to this Agreement, no party admits or acknowledges
the existence of any liability or wrongdoing. The provisions of this Agreement
shall not be construed as an admission of liability or wrongdoing by any party.

         9.       ADVICE OF COUNSEL. In executing this Agreement, each party
represents and warrants to the other that he, she or it has relied upon the
legal advice of his, her or its own attorney, that the provisions of this
Agreement have been completely read and explained by his, her or its attorney,
and that the provisions of this Agreement are fully understood and voluntarily
accepted by him, her or it.

         10.      REPRESENTATIONS, WARRANTIES AND AGREEMENTS. In addition to the
representations, warranties and agreements contained elsewhere in this
Agreement, the Path 1 Parties, on the one hand, and the Berns Parties, on the
other hand, each hereby represents and warrants to and agrees with the others as
follows:

                  10.1     This Agreement and the execution, delivery and
performance hereof by them (a) have been duly authorized and approved by all
necessary action on their part and (b) do not require the consent or approval of
any other person.

                  10.2     Except for the assignment of claims by Douglas A.
Palmer and Ronald D. Fellman to Path 1 (all of whom are parties to this
Agreement and the mutual release in

                                       6

<PAGE>

Section 5), they have not heretofore assigned, transferred or pledged, or
purported to assign, transfer or pledge, voluntarily, involuntarily or by
operation of law, to any person, any interest in any of the claims released by
them under Section 5.

                  10.3     They agree to protect, defend, indemnify and hold
harmless the other parties from and against any and all claims, losses, damages,
liabilities and expenses, including attorneys' fees, arising from or on account
of any misrepresentation, breach of warranty or failure to perform any of their
representations, warranties, covenants or agreements contained in this
Agreement.

         11.      GENERAL PROVISIONS.

                  11.1     PUBLIC ANNOUNCEMENTS. Path 1 agrees to consult with
the Berns Parties before issuing any press release or otherwise making any
public statement (other than in reports required to be filed with the Securities
and Exchange Commission pursuant to federal securities laws) with respect to
this Agreement, the settlement of the Lawsuit or the Delaware Action or the sale
and purchase of the Berns Path 1 Shares. All press releases and other public
statements with respect to this Agreement, the settlement of the Lawsuit or the
Delaware Action or the sale and purchase of the Berns Path 1 Shares shall be
subject to the Berns Parties' prior written approval which shall not be
unreasonably withheld.

                  11.2     ATTORNEYS' FEES. In any action or proceeding
(including, but not limited to, arbitration, appellate and bankruptcy
proceedings) arising out of or relating to this Agreement or to the subject
matter, enforcement or breach hereof, the prevailing party shall be entitled to
reasonable attorneys' fees, costs and expenses (including, but not limited to,
litigation expenses such as expert witness fees, copying costs and postage,
delivery, telephone and telecopying charges). This provision applies to this
entire Agreement and shall survive any resulting judgment, which the parties
agree shall contain an explicit provision that attorneys' fees incurred in
enforcing the judgment shall be included as costs collectible by the prevailing
party judgment creditor.

                  11.3     INTEGRATION. This Agreement is intended to be and
constitutes the final, complete and exclusive agreement between the parties
regarding the subject matter of this Agreement and all prior or contemporaneous
agreements, understandings, representations and statements, oral or written, are
merged into and superseded by this Agreement. No parol or extrinsic evidence of
any kind and no course of dealing or usage of trade or course of performance
shall be used to vary, contradict, supplement or add to the terms of this
Agreement.

                  11.4     AMENDMENT. No amendment, modification, termination or
waiver of this Agreement or any of its provisions shall be valid unless the same
is in writing and signed by the party against which such amendment,
modification, termination or waiver is sought to be enforced.

                  11.5     WAIVER. No waiver of any breach of any provision or
condition of this Agreement shall be deemed a waiver of a breach of a similar or
dissimilar provision or condition at the same time or any prior or subsequent
time or of the provision or condition itself.

                                       7

Agreement and each of its provisions in which a time for performance is
specified.

                  11.7     BINDING EFFECT. This Agreement shall bind and inure
to the benefit of the parties hereto and their respective successors, assigns

other party shall have any rights under or be deemed a beneficiary of this
Agreement.

                  11.8     COOPERATION. Each party shall execute and deliver or
cause to be executed and delivered such further instruments and documents and
shall take such further action as may be reasonably required to effectuate the
provisions of this Agreement.

                  11.9     SURVIVAL. All representations, warranties, covenants
and agreements contained in this Agreement shall survive the execution and
delivery hereof, the Closing and any and all performances in accordance with

and construed and enforced in accordance with the laws of the State of
California.

                  11.11    WARRANTY OF AUTHORITY. The persons signing this
Agreement represent and warrant that they have the requisite authority to bind
the parties on whose behalf they are signing.

                  11.12    RULES OF CONSTRUCTION. The section headings contained
in this Agreement are for reference purposes only and shall not affect the
meaning or interpretation of this Agreement. References to a section without
further attribution shall refer to the sections of this Agreement. When
indicated by the context, each number, both singular and plural, includes all
numbers, and each gender includes all genders. As used herein, the terms
"include," "including" and similar terms shall be construed as if followed by
the words "without limitation;" the term "person" includes natural person, firm,
partnership, corporation, limited liability company, association and any other
private or public entity; and the term "provisions" shall be construed as if
followed by the words "covenants, agreements, representations, warranties,

                  11.13    SEVERABILITY. If any one or more of the provisions of
this Agreement shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Agreement and this Agreement shall
be construed as if such invalid, illegal or unenforceable provisions had never
been contained herein.

                  11.14    COUNTERPARTS. This Agreement may be executed in
multiple counterparts, each of which shall be deemed an original, but all of
which, together, shall constitute one and the same instrument.

                  11.15    INTERPRETATION OF AGREEMENT. This Agreement has been
negotiated at arm's length and each party has been represented by independent
legal counsel of his own choice and representing his own interests. Accordingly,
any rule of law (including, but not limited to,

                                       8

<PAGE>

California Civil Code Section 1654) or legal decision that would require
interpretation of any ambiguities in this Agreement against the party that has
drafted it is not applicable and is waived.

                  11.16    EQUITABLE REMEDIES. The parties agree that they would
be irreparably damaged if the provisions of this Agreement were not capable of
being specifically enforced. Accordingly, the parties agree that the provisions
of this Agreement shall be specifically enforceable, that any violation of any
provision of this Agreement may be enjoined or restrained and that such
equitable relief shall not in any way limit or deny any other remedy which the
parties may have under this Agreement or at law.

                  11.17    EFFECTIVENESS OF AGREEMENT. This Agreement shall
become effective when it has been executed and delivered by all of the parties
hereto. Facsimile signatures and delivery by facsimile transmission shall be
