                     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
Corporation.

                  1.4      The parties desire to settle any and all disputes
presently existing between them in accordance with the provisions of this
Agreement.

         2.       CLOSING. The closing under this Agreement ("Closing") shall be
deemed to have occurred when (a) this Agreement has been duly executed and
delivered by all of the parties hereto and (b) all of the other conditions
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
before the Closing shall be deemed to have been taken and executed
simultaneously at the Closing and no such action shall be deemed taken nor any
such documents executed or delivered until all have been taken, executed and
delivered, unless waived by the party benefited by any condition, or agreed
otherwise by the parties in writing on or before the Closing. The parties agree
to use their best efforts to satisfy the conditions to Closing. If the Closing
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
the Closing occurs, Path 1 or the Berns Parties, if not then in breach or

<PAGE>

Agreement will constitute when executed, the valid and legally binding
obligations of Path 1 enforceable against Path 1 in accordance with their terms.

                  4.2      Neither the execution, delivery or performance of
this Agreement or any agreement, instrument or document required to be delivered
pursuant to this Agreement by Path 1, nor the consummation by Path 1 of the
transactions contemplated hereby and thereby, will, with or without the giving
of notice or lapse of time or both: (a) violate, conflict with or result in any
breach of any provision of the certificate of incorporation or bylaws of Path 1,

conditions or provisions of any contract or agreement to which Path 1 is a party
or, to the best knowledge of Path 1, by which it is bound, or (e) to the best
knowledge of Path 1, violate, conflict with or result in any breach of any law
applicable to Path 1.

         5.       MUTUAL GENERAL RELEASE.

                  5.1      Effective as of the Closing, and except for the
rights and obligations of the parties under this Agreement or any of the
documents delivered in connection with this Agreement, Path 1, Douglas A.
Palmer, Ronald D. Fellman, Roderick Adams and Paul Robinson (collectively, the

rights, claims, debts, contracts, liabilities, demands, obligations, costs,
charges, accounts, expenses, damages, actions and causes of action, of any kind
or nature whatsoever, which the releasor either had or now has or may hereafter
claim to have against the releasee by reason of any matter or thing whatsoever
occurring prior to the date hereof. The claims hereby released include, by way
of example and not by limitation, all claims directly or indirectly arising out
of, resulting from or relating in any way to the subject matter of the Lawsuit
or the Delaware Action, including but not limited to the filing, maintenance or
prosecution of the Lawsuit or the Delaware Action.

                  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,

representatives, insurers and attorneys.

                  5.5      Franklin Felber is not a party to, nor included

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.

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

any other person.
