                        PATH 1 NETWORK TECHNOLOGIES INC.

                      1999 STOCK OPTION/STOCK ISSUANCE PLAN

                                   ARTICLE 1

                               GENERAL PROVISIONS

         I.       PURPOSE OF THE PLAN

                  This 1999 Stock Option/Stock Issuance Plan is intended to
promote the interests of Path 1 Network Technologies Inc., a Delaware
corporation, by providing eligible persons in the Corporation's employ or
service with the opportunity to acquire a proprietary interest, or otherwise
increase their proprietary interest, in the Corporation as an incentive for them
to continue in such employ or service.

                  Capitalized terms herein shall have the meanings assigned to
such terms in the attached Appendix.

         II.      STRUCTURE OF THE PLAN

                  A. The Plan shall be divided into two separate equity
programs:

                                    (i) the Option Grant Program under which
eligible persons may, at the discretion of the Plan Administrator, be granted
options to purchase shares of Common Stock, and

                                    (ii) the Stock Issuance Program under which
eligible persons may, at the discretion of the Plan Administrator, be issued
shares of Common Stock directly, either through the immediate purchase of such
shares or as a bonus for services rendered the Corporation (or any Parent or
Subsidiary).

                  B. The provisions of Articles One and Four shall apply to both
equity programs under the Plan and shall accordingly govern the interests of all
persons under the Plan.

         III.     ADMINISTRATION OF THE PLAN

                  A. The Plan shall be administered by the Board. However, any
or all administrative functions otherwise exercisable by the Board may be
delegated to the Committee. Members of the Committee shall serve for such period
of time as the Board may determine and shall be subject to removal by the Board
at any time. The Board may also at any time terminate the functions of the
Committee and reassume all powers and authority previously delegated to the
Committee.

                  B. The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for

<PAGE>

proper administration of the Plan and to make such determinations under, and
issue such interpretations of, the Plan and any outstanding options or stock
issuances thereunder as it may deem necessary or advisable. Decisions of the
Plan Administrator shall be final and binding on all parties who have an
interest in the Plan or any option or stock issuance thereunder.

         IV.      ELIGIBILITY

                  A. The persons eligible to participate in the Plan are as
follows:

                                    (i)  Employees,

                                    (ii) non-employee members of the Board or
the non-employee members of the board of directors of any Parent or Subsidiary,
and

                                    (iii) consultants and other independent
advisors who provide services to the Corporation (or any Parent or Subsidiary).

                  B. The Plan Administrator shall have full authority to
determine, (i) with respect to the grants made under the Option Grant Program,
which eligible persons are to receive the option grants, the time or times when
those grants are to be made, the number of shares to be covered by each such
grant, the status of the granted option as either an Incentive Option or a
Non-Statutory Option, the time or times when each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding, and (ii) with
respect to stock issuances made under the Stock Issuance Program, which eligible
persons are to receive such stock issuances, the time or times when those
issuances are to be made, the number of shares to be issued to each Participant,
the vesting schedule (if any) applicable to the issued shares and the
consideration to be paid by the Participant for such shares.

                  C. The Plan Administrator shall have the absolute discretion
either to grant options in accordance with the Option Grant Program or to effect
stock issuances in accordance with the Stock Issuance Program.

         V.       STOCK SUBJECT TO THE PLAN

                  A. The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock. The maximum number of shares
of Common Stock which may be issued over the term of the Plan shall not exceed
2,500,000 shares.

                  B. Shares of Common Stock subject to outstanding options shall
be available for subsequent issuance under the Plan to the extent (i) the
options expire or terminate for any reason prior to exercise in full or (ii) the
options are cancelled in accordance with the cancellation-regrant provisions of
Article Two. Unvested shares issued under the Plan and subsequently repurchased
by the Corporation, at the option exercise or direct issue price paid per share,
pursuant to the Corporation's repurchase rights under the Plan shall be added
back to the number of shares of Common Stock reserved for issuance under the
Plan and shall accordingly be

<PAGE>

available for reissuance through one or more subsequent option grants or direct
stock issuances under the Plan.

                  C. Should any change be made to the Common Stock by reason of
any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and/or class of securities
issuable under the Plan and (ii) the number and/or class of securities and the
exercise price per share in effect under each outstanding option in order to
prevent the dilution or enlargement of benefits thereunder. The adjustments
determined by the Plan Administrator shall be final, binding and conclusive.

                                   ARTICLE 2

                              OPTION GRANT PROGRAM

         I.       OPTION TERMS

                  Each option shall be evidenced by one or more documents in the
form approved by the Plan Administrator; PROVIDED, however, that each such
document shall comply with the terms specified below. Each document evidencing
an Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to Incentive Options.

                  A.       EXERCISE PRICE.

                           1. The exercise  price per share shall be fixed by
the Plan Administrator at the time of grant.

                           2. The exercise price shall become immediately due
upon exercise of the option and shall, subject to the provisions of Section I of
Article Four and the documents evidencing the option, be payable in cash or
check made payable to the Corporation. Should the Common Stock be registered
under Section 12 of the 1934 Act at the time the option is exercised, then the
exercise price may also be paid as follows:

                                    (i) in shares of Common Stock held for the
requisite period necessary to avoid a charge to the Corporation's earnings for
financial reporting purposes and valued at Fair Market Value on the Exercise
Date, or

                                    (ii) to the extent the option is exercised
for vested shares, through a special sale and remittance procedure pursuant to
which the Optionee shall concurrently provide irrevocable instructions (A) to a
Corporation-designated brokerage firm to effect the immediate sale of the
purchased shares and remit to the Corporation, out of the sale proceeds
available on the settlement date, sufficient funds to cover the aggregate
exercise price payable for the purchased shares plus all applicable Federal,
state and local income and employment taxes required to be withheld by the
Corporation by reason of such

<PAGE>

exercise and (B) to the Corporation to deliver the certificates for the
purchased shares directly to such brokerage firm in order to complete the sale.

                  Except to the extent such sale and remittance procedure is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

                  B. EXERCISE AND TERM OF OPTIONS.

                  Each option shall be exercisable at such time or times,
during such period and for such number of shares as shall be determined by
the Plan Administrator and set forth in the documents evidencing the option
grant. However, no option shall have a term in excess of ten (10) years
measured from the option grant date.

                  C. EFFECT OF TERMINATION OF SERVICE.

                           1. The following provisions shall govern the exercise
of any options held by the Optionee at the time of cessation of Service or
death:

                                    (i) Should the Optionee cease to remain in
Service for any reason other than death, Disability or Misconduct, then the
Optionee shall have a period of three months following the date of such
cessation of Service during which to exercise each outstanding option held by
such Optionee.

                                    (ii) Should Optionee's Service terminate by
reason of Disability, then the Optionee shall have a period of twelve (12)
months following the date of such cessation of Service during which to exercise
each outstanding option held by such Optionee.

                                    (iii) If the Optionee dies while holding an
outstanding option, then the personal representative of his or her estate or the
person or persons to whom the option is transferred pursuant to the Optionee's
will or the laws of inheritance shall have a twelve (12)-month period following
the date of the Optionee's death to exercise such option.

                                    (iv) Under no circumstances, however, shall
any such option be exercisable after the specified expiration of the option
term.

                                    (v) During the applicable post-Service
exercise period, the option may not be exercised in the aggregate for more than
the number of vested shares for which the option is exercisable on the date of
the Optionee's cessation of Service. Upon the expiration of the applicable
exercise period or (if earlier) upon the expiration of the option term, the
option shall terminate and cease to be outstanding for any vested shares for
which the option has not been exercised. However, the option shall, immediately
upon the Optionee's cessation of Service, terminate and cease to be outstanding
with respect to any and all option shares for which the option is not otherwise
at the time exercisable or in which the Optionee is not otherwise at that time
vested.

                                    (vi) Should Optionee's Service be terminated
for Misconduct, then all

<PAGE>

outstanding options held by the Optionee shall terminate immediately and cease
to remain outstanding.

                           2. The Plan Administrator shall have the discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

                                    (i) extend the period of time for which the
option is to remain exercisable following Optionee's cessation of Service or
death from the limited period otherwise in effect for that option to such
greater period of time as the Plan Administrator shall deem appropriate, but in
no event beyond the expiration of the option term, and/or

                                    (ii) permit the option to be exercised,
during the applicable post-Service exercise period, not only with respect to the
number of vested shares of Common Stock for which such option is exercisable at
the time of the Optionee's cessation of Service but also with respect to one or
more additional installments in which the Optionee would have vested under the
option had the Optionee continued in Service.

                  D. STOCKHOLDER RIGHTS.

                  The holder of an option shall have no stockholder rights with
respect to the shares subject to the option until such person shall have
exercised the option, paid the exercise price and become the recordholder of the
purchased shares.

                  E. UNVESTED SHARES.

                  The Plan Administrator shall have the discretion to grant
options which are exercisable for unvested shares of Common Stock. Should the
Optionee cease Service while holding such unvested shares, the Corporation shall
have the right to repurchase, at the exercise price paid per share, any or all
of those unvested shares. The terms upon which such repurchase right shall be
exercisable (including the period and procedure for exercise and the appropriate
vesting schedule for the purchased shares) shall be established by the Plan
Administrator and set forth in the document evidencing such repurchase right.
The Plan Administrator may not impose a vesting schedule upon any option grant
or the shares of Common Stock subject to that option which is more restrictive
than twenty percent (20%) per year vesting, with the initial vesting to occur
not later than one year after the option grant date. However, such limitation
shall not be applicable to any option grants made to individuals who are
officers of the Corporation, non-employee Board members or independent
consultants.

                  F. LIMITED TRANSFERABILITY OF OPTIONS.

                  During the lifetime of the Optionee, Incentive Options shall
be exercisable only by the Optionee and shall not be assignable or transferable
other than by will or by the laws of descent and distribution following the
Optionee's death. Non-Statutory Options may, to the extent permitted by the Plan
Administrator, be assigned in whole or in part during the Optionee's lifetime to
one or more members of the Optionee's immediate family or to a trust established
exclusively for one or more such family members. The terms applicable to the
assigned portion

<PAGE>

shall be the same as those in effect for the option immediately prior to such
assignment and shall be set forth in such documents issued to the assignee as
the Plan Administrator may deem appropriate.

         II.      INCENTIVE OPTIONS

                  The terms specified below shall be applicable to all Incentive
Options. Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Four shall be applicable to Incentive
Options. Options which are specifically designated as Non-Statutory Options
shall NOT be subject to the terms of this Section II.

                  A. ELIGIBILITY.

                  Incentive Options may only be granted to Employees.

                  B. EXERCISE PRICE.

                  The exercise price per share shall not be less than one
hundred percent (100%) of the Fair Market Value per share of Common Stock on the
option grant date.

                  C. DOLLAR LIMITATION.

                  The aggregate Fair Market Value of the shares of Common Stock
(determined as of the respective date or dates of grant) for which one or more
options granted to any Employee under the Plan (or any other option plan of the
Corporation or any Parent or Subsidiary) may for the first time become
exercisable as Incentive Options during any one calendar year shall not exceed
the sum of One Hundred Thousand Dollars ($100,000). To the extent the Employee
holds two or more such options which become exercisable for the first time in
the same calendar year, the foregoing limitation on the exercisability of such
options as Incentive Options shall be applied on the basis of the order in which
such options are granted.

                  D. 10% STOCKHOLDER.

                  If any Employee to whom an Incentive Option is granted is a
10% Stockholder, then the option term shall not exceed five years measured from
the option grant date and the exercise price per share shall not be less than
one hundred ten percent (110%) of the Fair Market Value per share of Common
Stock on the option grant date.

         III.     CORPORATE TRANSACTION

                  A. The Plan does not provide for automatic acceleration of
unvested shares in the event of a Corporate Transaction, although the Plan
Administrator has discretion to grant individual options which so provide. In
the event of a Corporate Transaction, all options shall be assumed or equivalent
options shall be substituted by the successor corporation (or other entity) or a
parent or subsidiary of such successor corporation (or other entity). If such
successor does not agree to assume the options or to substitute equivalent
options therefor, unless the Plan Administration shall determine otherwise, such
options will expire upon such event.

<PAGE>

                  B. In the event of the proposed dissolution or liquidation of
the Company, the Plan Administrator shall notify each Optionee at least thirty
(30) days prior to such proposed action. To the extent not previously exercised,
all options will terminate immediately prior to consummation of such proposed
action.

                  C. Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction, had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the number and class of
securities available for issuance under the Plan following the consummation of
such Corporate Transaction and (ii) the exercise price payable per share under
each outstanding option, PROVIDED the aggregate exercise price payable for such
securities shall remain the same.

                  D. The grant of options under the Plan shall in no way affect
the right of the Corporation to adjust, reclassify, reorganize or otherwise
change its capital or business structure or to merge, consolidate, dissolve,
liquidate or sell or transfer all or any part of its business or assets.

         IV.      CANCELLATION AND REGRANT OF OPTIONS

                  The Plan Administrator shall have the authority to effect, at
any time and from time to time, with the consent of the affected option holders,
the cancellation of any or all outstanding options under the Plan and to grant
in substitution therefor new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                                   ARTICLE 3

                             STOCK ISSUANCE PROGRAM

         I.       STOCK ISSUANCE TERMS

                  Shares of Common Stock may be issued under the Stock Issuance
Program through direct and immediate issuances without any intervening option
grants. Each such stock issuance shall be evidenced by a Stock Issuance
Agreement which complies with the terms specified below.

                  A.       PURCHASE PRICE.

                           1.       The  purchase  price per  share  shall be
fixed by the Plan  Administrator but shall not be less than the par value per
share of Common Stock.

                           2. Subject to the provisions of Section I of Article
Four, shares of Common Stock may be issued under the Stock Issuance Program for
any of the following items of consideration which the Plan Administrator may
deem appropriate in each individual instance:

<PAGE>

                                    (i)  cash or check made payable to the
Corporation, or

                                    (ii) past services rendered to the
Corporation (or any Parent or Subsidiary).

                  B.       VESTING PROVISIONS.

                           1. Shares of Common Stock issued under the Stock
Issuance Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives. However, the Plan Administrator may not impose a vesting schedule
upon any stock issuance effected under the Stock Issuance Program which is more
restrictive than twenty percent (20%) per year vesting, with initial vesting to
occur not later than one year after the issuance date. Such limitation shall not
apply to any Common Stock issuances made to the officers of the Corporation,
non-employee Board members or independent consultants.

                           2. Any new, substituted or additional securities or
other property (including money paid other than as a regular cash dividend)
which the Participant may have the right to receive with respect to the
Participant's unvested shares of Common Stock by reason of any stock dividend,
stock split, recapitalization, combination of shares, exchange of shares or
other change affecting the outstanding Common Stock as a series or class without
the Corporation's receipt of consideration shall be issued subject to (i) the
same vesting requirements applicable to the Participant's unvested shares of
Common Stock and (ii) such escrow arrangements as the Plan Administrator shall
deem appropriate.

                           3. The Participant shall have full stockholder rights
with respect to any shares of Common Stock issued to the Participant under the
Stock Issuance Program, whether or not the Participant's interest in those
shares is vested. Accordingly, the Participant shall have the right to vote such
shares and to receive any regular cash dividends paid on such shares.

                           4. Should the Participant cease to remain in Service
while holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares. To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to such surrendered shares.

                           5. The Plan Administrator may in its discretion waive
the surrender and cancellation of one or more unvested shares of Common Stock
(or other assets attributable thereto) which would otherwise occur upon the
non-completion of the vesting schedule applicable to those shares. Such waiver
shall result in the immediate vesting of the Participant's

<PAGE>

interest in the shares of Common Stock as to which the waiver applies. Such
waiver may be effected at any time (including prospective effectuation, in the
Stock Issuance Agreement or in any other written agreement), whether before or
after the Participant's cessation of Service or the attainment or non-attainment
of the applicable performance objectives.

         II.      CORPORATE TRANSACTION

                  The Plan does not provide for automatic acceleration of
unvested shares in the event of a Corporate Transaction, although the Plan
Administrator has discretion to award individual stock issuances which so
provide.

         III.     SHARE ESCROW/LEGENDS

                  Unvested shares may, in the Plan Administrator's discretion,
be held in escrow by the Corporation until the Participant's interest in such
shares vests or may be issued directly to the Participant with restrictive
legends on the certificates evidencing those unvested shares.

                                   ARTICLE 4

                                  MISCELLANEOUS

         I.       FINANCING

                  The Plan Administrator may permit any Optionee or Participant
to pay the option exercise price under the Option Grant Program or the purchase
price for shares issued under the Stock Issuance Program by delivering a
full-recourse, interest bearing promissory note payable in one or more
installments and secured by the purchased shares. The terms of any such
promissory note (including the interest rate and the terms of repayment) shall
be established by the Plan Administrator in its sole discretion. In no event may
the maximum credit available to the Optionee or Participant exceed the sum of
(i) the aggregate option exercise price or purchase price payable for the
purchased shares (less the par value of those shares) plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee or
the Participant in connection with the option exercise or share purchase.

         II.      EFFECTIVE DATE AND TERM OF PLAN

                  A. The Plan shall become effective when adopted by the Board,
but no option granted under the Plan may be exercised, and no shares shall be
issued under the Plan, until the Plan is approved by the Corporation's
stockholders. If such stockholder approval is not obtained within twelve (12)
months after the date of the Board's adoption of the Plan, then all options
previously granted under the Plan shall terminate and cease to be outstanding,
and no further options shall be granted and no shares shall be issued under the
Plan. Subject to such limitation, the Plan Administrator may grant options and
issue shares under the Plan at any time after the effective date of the Plan and
before the date fixed herein for termination of the Plan.

                  B. The Plan shall terminate upon the EARLIEST of (i) the
expiration of the ten (10)-year

<PAGE>

period measured from the date the Plan is adopted by the Board, (ii) the date on
which all shares available for issuance under the Plan shall have been issued as
vested shares or (iii) the termination of all outstanding options in connection
with a Corporate Transaction. All options and unvested stock issuances
outstanding at the time of a clause (i) termination event shall continue to have
full force and effect in accordance with the provisions of the documents
evidencing those options or issuances.

         III.     AMENDMENT OF THE PLAN

                  A. The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects. However, no such
amendment or modification shall adversely affect the rights and obligations with
respect to options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
pursuant to applicable laws and regulations.

                  B. Options may be granted under the Option Grant Program and
shares may be issued under the Stock Issuance Program which are in each instance
in excess of the number of shares of Common Stock then available for issuance
under the Plan, provided any excess shares actually issued under those programs
shall be held in escrow until there is obtained stockholder approval of an
amendment sufficiently increasing the number of shares of Common Stock available
for issuance under the Plan. If such stockholder approval is not obtained within
twelve (12) months after the date the first such excess grants or issuances are
made, then (i) any unexercised options granted on the basis of such excess
shares shall terminate and cease to be outstanding and (ii) the Corporation
shall promptly refund to the Optionees and the Participants the exercise or
purchase price paid for any excess shares issued under the Plan and held in
escrow, together with interest (at the applicable Short Term Federal Rate) for
the period the shares were held in escrow, and such shares shall thereupon be
automatically cancelled and cease to be outstanding.

         IV.      USE OF PROCEEDS

                  Any cash proceeds received by the Corporation from the sale of

The Company is a corporation validly existing and in good standing under the
laws of the State of Delaware, and has all requisite corporate power and
authority to own, operate and lease its assets and properties and to conduct the
businesses in which it is now engaged. The Company is duly qualified to transact

Purchaser by the Company concurrently with the execution hereof (the "Company
Disclosure Schedule"). The Company does not own any capital stock or other

proprietary interest.

                  2.2      CONFLICTS. Neither the execution and delivery of this
Agreement by the Company, nor the consummation of the transactions contemplated
hereby (the "Transactions") to be consummated by the Company, (a) violates any
provision of the Certificate of Incorporation or By-laws of the Company or (b)
constitutes a violation of any Applicable Law. Except as set forth in Section
2.2 of the Company Disclosure Schedule, neither the execution and delivery of
this Agreement by the Company, nor the consummation of the Transactions
contemplated hereby to be consummated by the Company, violates, conflicts with,
results in any breach of any of the terms of, or results in the termination of
or the creation of any Lien pursuant to the terms of any material agreement,
instrument, or contract to which the Company is a party or by which it is bound,
except where such violation, conflict, breach, termination or Lien would not
have a Company Material Adverse Effect.

                  2.3      CAPITALIZATION. The authorized capital stock of the
Company consists of: (i) 20,000,000 shares of Path 1 Class A Common Stock, of
which, as of the date hereof, 6,462,651 shares were issued and outstanding, (ii)

the same number of shares of Path 1 Class A Common Stock, (ii) 642,996 options
to purchase the same number of shares of Path 1 Class B Common Stock and (iii)
up to a maximum of 650,000 options to purchase the same number of shares of Path

warrants, rights, convertible or exchangeable securities, proxy or stockholders'
agreements or agreements of any kind for the purchase or acquisition from, or
issuance by, the Company of any of its securities. Except for the Stockholders'
Agreement, there are no outstanding agreements or other arrangements to which
the Company is a party concerning the voting of any shares of capital stock of
the Company or which obligate the Company to redeem or otherwise acquire from
any Person any shares of capital stock of the Company. All outstanding shares of

                           (a)      On March 23, 2000, the Company re-filed a
General Form for Registration of Securities on Form 10 (the "Form 10") with the

of the Exchange Act, and the published rules and regulations of the SEC
thereunder. The Form 10 will not, on the effective date thereof, contain any

material liabilities or obligations of any nature (whether accrued, absolute,
contingent or otherwise) required by GAAP to be recognized or disclosed on a
balance sheet of the Company or in the notes thereto.

Balance Sheet, (i) the Company has conducted its business in the ordinary and
usual course consistent with past practice, and (ii) there has not occurred any

                  2.23     INVESTMENT. Without limiting the effect of Article
VIII hereof:

                           (a)      The Company understands that Purchaser
proposes to issue and deliver to the Company the Leitch Shares pursuant to this
Agreement without registration under the Securities Act of 1933, as amended (the
"Securities Act") or under any other Applicable Law; that for such purpose
Purchaser will rely upon the Company's representations and warranties contained
herein; and that registration under the Securities Act may be required if such
representations and warranties are not correct.

                           (b)      The Company has received such information
relating to the business and affairs of Purchaser which could reasonably be
deemed necessary or appropriate by the Company, and all additional information
which is necessary to verify the accuracy of the information so received. The
Company has had the opportunity to ask questions of and receive answers from
Purchaser concerning the business and affairs of Purchaser and concerning terms
and conditions of the Transactions. On the basis of the foregoing, the Company

issued to the Company pursuant to this Agreement, except to the extent that such
shares may be sold (i) pursuant to an effective registration statement covering

purchaser who shall be subject to the same restrictions on any resale or (iii)

                           (d)      The Company is not relying on Purchaser
respecting the financial, tax and other economic considerations of an investment
in the Leitch Shares issued to the Company pursuant to this Agreement, and the
Company has relied on the advice of, or has consulted with, its own advisors.

                           (e)      The Company is familiar with the provisions
of Rule 144 and Rule 904 and the limitations upon the availability and
applicability of such rules.

                           (f)      The Company is an "accredited investor"
within the meaning of Regulation D under the Securities Act and is a
sophisticated investor familiar with the type of risks inherent in the
acquisition of restricted securities such as the Leitch Shares issued to the
Company pursuant to this Agreement, and its financial position is such that it
can afford to retain such shares for an indefinite period of time without
realizing any direct or indirect cash return on its investment.

                           (g)      The Company has such knowledge and
experience in financial, tax and business matters so as to enable it to utilize
the information made available to it in connection with the issuance of the
Leitch Shares issued to the Company pursuant to this Agreement to evaluate the
merits and risks of an investment in such shares and to make an informed
investment decision with respect thereto.

                           (h)      The Company is acquiring the Leitch Shares
issued to the Company pursuant to this Agreement as an investment for its
account, and without any present view towards the resale or other distribution
thereof.

                           (i)      The Company has been independently advised
as to or is aware of the restrictions with respect to trading in the Leitch
Shares imposed by applicable securities legislation in the jurisdiction in which
it resides and confirms that no representation has been made respecting such
restrictions with respect to trading in the Leitch Shares.

                           (j)      The Company acknowledges that the Leitch
Shares are not qualified for distribution to the public in Canada. The Company
certifies that (a) the Company is not a Canadian resident nor acting for the
account or benefit of a Canadian resident; (b) the Leitch Shares were not
offered to the Company in Canada, and the Company was, at the time of agreeing
to sell the Path 1 Shares, and is outside Canada; and (c) for a period ending 40
days after the date of issuance of the Leitch Shares to the Company, the Company
will not resell the Leitch Shares to any Canadian resident or in Canada and,
thereafter, any resale by the Company to a Canadian resident or in Canada will
be made in accordance with applicable securities laws of the provinces and
territories of Canada.

                  2.24     LEGEND. Each certificate representing Leitch Shares
issued to the Company pursuant to this Agreement, shall contain upon its face or
upon the reverse side thereof a legend to the following effect:

                  "These securities have not been registered under the
                  Securities Act of 1933, as amended (the "Securities Act"), or
                  qualified for distribution to the public in Canada or
                  qualified under state securities laws and may not be sold,
                  pledged, or otherwise

                                       8

                  transferred unless (a) covered by an effective registration
                  statement under the Securities Act, and qualified under
                  applicable state securities laws; (b) sold outside the United
                  States in accordance with Rule 904 of Regulation S under the
                  Securities Act; (c) pursuant to an exemption from registration
                  under the Securities Act provided by Rule 144 thereunder, if
                  available; or (d) in compliance with certain other procedures
                  satisfactory to Leitch Technology Corporation upon the
                  furnishing to Leitch Technology Corporation of an opinion from
                  counsel of recognized national standing in form and substance
                  satisfactory to Leitch Technology Corporation to the effect
                  that no registration or qualification is legally required for
                  such transfer. The holder hereof, by acquiring such
                  securities, agrees for the benefit of Leitch Technology
                  Corporation that for a period ending 40 days after the date of
                  the issuance of those securities by Leitch Technology
                  Corporation, the holder will not resell those securities to
                  any Canadian resident or in Canada. Delivery of this
                  certificate may not constitute "good delivery" in settlement
                  of transactions on the Toronto Stock Exchange. A new
                  certificate, bearing no legend, delivery of which will
                  constitute "good delivery", may be obtained from Leitch
                  Technology Corporation's Transfer Agent in connection with a
                  sale made pursuant to Rule 904 of Regulation S at a time
                  Leitch Technology Corporation is a "foreign private issuer" as
                  defined in Rule 405 under the Securities Act upon delivery of
                  this certificate after 40 days after the issuance of the
                  securities by Leitch Technology Corporation and a duly
                  executed declaration, in a form satisfactory to such Transfer
                  Agent and Leitch Technology Corporation, to the effect that
                  (A) the sale of the securities represented hereby is being
                  made in compliance with Rule 904 of Regulation S under the
                  Securities Act; and (B) certifying that (1) the buyer is not
                  an "Affiliate" (as defined in Rule 405 under the Securities
                  Act) of Leitch Technology Corporation; (2) the offer of such
                  securities was not made to a person in the United States and
                  either (x) at the time the buy order was originated, the buyer
                  was outside the United States, or Path 1 Network Technologies,
                  Inc. and any person acting on its behalf reasonably believe
                  that the buyer was outside the United States, or (y) the
                  transaction was executed on or through the facilities of the
                  Toronto Stock Exchange and neither Path 1 Network
                  Technologies, Inc. nor any person acting its behalf knows that
                  the transaction has been prearranged with a buyer in the
                  United States; (3) neither Path 1 Network Technologies, Inc.
                  nor any person acting on its behalf engaged in any directed
                  selling efforts in connection with the offer and sale of such
                  securities; (4) the sale is bona fide and not for the purpose
                  of "washing off" resale restrictions imposed because the
                  securities are "restricted securities"; and (5) the sale is
                  not a

                  Securities Act. Terms used herein have the meanings given to

connection with the execution and delivery of this Agreement by Purchaser and
the consummation of the Transactions contemplated hereby to be consummated by

Adverse Effect.

power and authority to execute and deliver this Agreement and to consummate the
Transactions. The execution, delivery and performance of this Agreement and the

except that the enforcement hereof may be limited (i) by bankruptcy, insolvency,
reorganization, moratorium or other similar laws now or hereafter in effect
relating to creditors' rights generally, (ii) by general principles of equity
(regardless of whether enforceability is considered in a proceeding in equity or

Purchaser Disclosure Documents complied in all material respects with the
requirements of the Ontario Securities Act, the rules and regulations of
Governmental Authorities under the Ontario Securities Act, other Applicable Law,
and the Exchange Filing Requirements. As of their filing dates or effective
dates (whichever is later), none of the Purchaser Disclosure Documents contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading.

                  3.9      FULL DISCLOSURE. No representation or warranty by
Purchaser in this Agreement and no statement by Purchaser contained in any
exhibit, disclosure schedule, or certificate contemplated by this Agreement
contains or will contain any untrue statement of material fact or omits or will
omit to state any material fact necessary, in light of the circumstances under
which it was made, in order to make the statements herein or therein not
misleading.

                  3.10     INVESTMENT. Without limiting the effect of Article
VIII hereof:

                           (a)      Purchaser understands that the Company
proposes to issue and deliver to Purchaser Path 1 Shares pursuant to this
Agreement without registration under the Securities Act; that for such purpose
the Company will rely upon Purchaser's representations and warranties contained
herein; and that registration under the Securities Act may be required if such
representations and warranties are not correct.

                           (b)      Purchaser has received such information
relating to the business and affairs of the Company which Purchaser has
requested, and all additional information which Purchaser has considered
necessary to verify the accuracy of the information so received. Purchaser has
had the opportunity to ask questions of and receive answers from the Company
concerning the business and affairs of the Company and concerning terms and
conditions of the Transactions. On the basis of the foregoing, Purchaser is
familiar with the operations, business plans and financial condition of the
Company.

                           (c)      Purchaser understands that, under the
existing rules of the SEC, Purchaser may be unable to sell the Path 1 Shares
issued to Purchaser pursuant to this Agreement, except to the extent that such
shares may be sold (i) pursuant to an effective registration statement covering
such sale pursuant to the Securities Act and applicable state securities laws or
an applicable exemption therefrom, (ii) in a bona fide private placement to a
purchaser who shall be subject to the same restrictions on any resale or (iii)
subject to the restrictions contained in Rule 144.

                           (d)      Purchaser is not relying on the Company
respecting the financial, tax and other economic considerations of an investment
in the Path 1 Shares issued to Purchaser pursuant to this Agreement, and
Purchaser has relied on the advice of, or has consulted with, its own advisors.

                                       12
<PAGE>

                           (e)      Purchaser is familiar with the provisions of
Rule 144 and the limitations upon the availability and applicability of such
rules.

                           (f)      Purchaser is an "accredited investor" within
the meaning of Regulation D under the Securities Act and is a sophisticated
investor familiar with the type of risks inherent in the acquisition of
restricted securities such as the Path 1 Shares issued to Purchaser pursuant to
this Agreement, and its financial position is such that it can afford to retain
such shares for an indefinite period of time without realizing any direct or
indirect cash return on its investment.

                           (g)      Purchaser has such knowledge and experience
in financial, tax and business matters so as to enable it to utilize the
information made available to it in connection with the issuance of the Path 1
Shares issued to Purchaser pursuant to this Agreement to evaluate the merits and
risks of an investment in such shares and to make an informed investment
decision with respect thereto.

                           (h)      Purchaser is acquiring the Path 1 Shares
issued to Purchaser pursuant to this Agreement as an investment for its account,
and without any present view towards the resale or other distribution thereof.

                           (i)      Purchaser has been independently advised as
to or is aware of the restrictions with respect to trading in the Path 1 Shares
imposed by applicable securities legislation in the jurisdiction in which it
resides and confirms that no representation has been made respecting such
restrictions with respect to trading in the Path 1 Shares.

                  3.11     LEGEND. Each certificate representing Path 1 Shares
issued to Purchaser pursuant to this Agreement, shall contain upon its face or
upon the reverse side thereof a legend as required by the Stockholders'
Agreement.

                  3.12     BROKERS AND FINDERS. Other than Yorkton Securities
Inc., Purchaser has not employed any investment banker, broker, finder, advisor,
consultant or intermediary in connection with the Transactions which would be
entitled to any investment banking, brokerage, finder's, advisory or similar fee
or commission in connection with this Agreement or the Transactions and the
Company does not, nor will it, have any obligation to pay Yorkton Securities
Inc. any fee or commission in connection with this Agreement or the consummation
of the Transactions.

                  3.13     LEITCH SHARES. Assuming (i) the accuracy of the
Company's representations and warranties as set forth in Section 2.23 hereof,
(ii) the Company's compliance with the requirements contained in the legend as
set forth in Section 2.24 hereof and (iii) that the Company does not hold, alone
or in combination with others, more than 20% of the outstanding voting
securities of Purchaser and does not otherwise hold a sufficient number of any
securities of Purchaser which would affect materially the control of Purchaser,
then the Leitch Shares will be freely tradeable through an appropriately
registered dealer in Canada.

                  4.2      ALTERNATIVE PROPOSALS.

                           (a)      Neither the Company nor any Affiliate shall

accountants, not to), directly or indirectly, solicit, participate in,
encourage, or initiate discussions or negotiations with, or provide any
information to, any Person (other than Purchaser, any of its Affiliates or
representatives) concerning or which would reasonably facilitate or be expected
to lead to any Takeover Proposal, except that nothing contained in this Section
4.2 or any other provision hereof shall prohibit the Company or the Company's
Board of Directors from making such disclosure to the Company's stockholders as,
in the good faith judgment of the Company's Board of Directors, after receiving
advice from

                                       16
<PAGE>

outside counsel, is required under Applicable Law, provided that the Company may
not, approve or recommend, or propose to approve or recommend, any Takeover
Proposal, or enter into any letter of interest, agreement or other arrangement
with respect to any Takeover Proposal. Upon execution of this Agreement, the
Company will immediately cease any existing activities, discussions or
negotiations with any Persons conducted heretofore with respect to any of the
foregoing. Notwithstanding the foregoing, prior to the Closing, the Company may
furnish information concerning its business, properties or assets to any Person
or group and may negotiate and participate in discussions and negotiations with
such Person or group concerning a Takeover Proposal if: the Company's Board of
Directors determines in good faith, after consultation with outside legal
counsel that such action is necessary for it to comply with its fiduciary duty
under Applicable Law.

                  The Company will promptly notify Purchaser of the existence of
any proposal, discussion, negotiation or inquiry received by the Company
regarding any Takeover Proposal, and the Company will promptly communicate to
Purchaser the terms of any proposal, discussion, negotiation or inquiry which it

materials received by the Company in connection with such proposal, discussion,
negotiation or inquiry) regarding any Takeover Proposal and the identity of the
party making such proposal or inquiry or engaging in such discussion or
negotiation. The Company will promptly provide to Purchaser any non-public
information concerning the Company provided to any other Person which was not
previously provided to Purchaser. The Company will keep Purchaser informed of
the status and details of any such Takeover Proposal and of any amendments or
proposed amendments to any Takeover Proposal and will promptly (but in no case
later than 24 hours) notify Purchaser of any determination by the Company's
Board of Directors that it is considering accepting a Takeover Proposal.

                  4.3      REASONABLE BEST EFFORTS.

                           (i)      Prior to the Closing, upon the terms and

advisable (subject to any Applicable Law) to consummate the Transactions as
promptly as practicable including, but not limited to (i) the preparation and
filing of all forms, registrations and notices required to be filed to
consummate the Transactions and the taking of such actions as are necessary to
obtain any requisite approvals, consents, orders, exemptions or waivers by any
third party or Governmental Entity and (ii) the satisfaction of the other
parties' conditions to effect the Transactions. In addition, no party hereto
shall take any action after the date hereof that would reasonably be expected to
delay the obtaining of, or result in not obtaining, any permission, approval or
consent from any Governmental Entity necessary to be obtained prior to the
Closing.

                           (b)      Prior to the Closing, subject to Applicable
Law, each party shall promptly consult with the other parties hereto with
respect to, provide any necessary information with respect to, and provide the
other parties (or their respective counsel) with copies of, all filings made by
such party with any Governmental Entity or any other information supplied by
such party to a Governmental Entity in connection with this Agreement, and the
Transactions. Each party hereto shall promptly inform the other parties of any
communication from any

                                       17
<PAGE>

Governmental Entity regarding any of the Transactions. If any party hereto or
Affiliate thereof receives a request for additional information or documentary
material from any such Governmental Entity with respect to any of the
Transactions, then such party shall endeavor in good faith to make, or cause to
be made, as soon as reasonably practicable and after consultation with the other
parties, an appropriate response in compliance with such request.

                           (c)      Notwithstanding the foregoing, nothing
contained in this Agreement shall be deemed to require the Company or Purchaser
to commence any litigation against any Person in order to facilitate the
consummation of any of the Transactions or, except for the Company, to defend
against any litigation brought by any Governmental Entity seeking to prevent the
consummation of any of the Transactions.

                  4.4      PURCHASER ACCESS TO INFORMATION. Upon reasonable
notice, the Company shall, afford to the officers, employees, accountants,
counsel, financing sources and other representatives of Purchaser, access,

concerning its business, properties and personnel as Purchaser may reasonably
request. Until the Closing, unless otherwise required by Applicable Law or in
order to comply with disclosure requirements applicable to any filings or
communications with Governmental Entities and stock exchanges, Purchaser will

of their respective Affiliates shall issue or cause the publication of any press
release or other announcement with respect to this Agreement or the other
Transactions without prior consultation with the other parties, except in order
to comply with fiduciary obligations or as may be required by Applicable law,
the rules and regulations of any national or other securities exchange or
over-the-counter market or by any listing agreement with a national or other
securities exchange or over-the-counter market.

                  4.6      NOTIFICATION OF CERTAIN MATTERS.The Company shall
give prompt notice to Purchaser of (i) the occurrence or non-occurrence of any
event known to the Company which would cause any representation or warranty of
the Company contained in this Agreement to be untrue or inaccurate in any
material respect at or prior to the Closing and (ii) any material failure of the
Company to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by such Person hereunder; PROVIDED, HOWEVER, that the
delivery of any notice pursuant to this Section 4.6 shall not limit or otherwise
affect the remedies available hereunder to the party receiving such notice.

                           (b)      Purchaser shall give prompt notice to the
Company of (i) the occurrence or non-occurrence of any event known to Purchaser
which would cause any representation or warranty of Purchaser contained in this
Agreement to be untrue or inaccurate in

                                       18
<PAGE>

any material respect at or prior to the Closing and (ii) any material failure of
Purchaser to comply with or satisfy any covenant, condition or agreement to be
complied with or satisfied by it hereunder; PROVIDED, HOWEVER, that the delivery
of any notice pursuant to this Section 4.6 shall not limit or otherwise affect
the remedies available hereunder to the party receiving such notice.

                  4.7      STOCK EXCHANGE LISTINGS AND FORM 10. Purchaser shall
use its reasonable best efforts to promptly cause the Leitch Shares to be issued
pursuant to this Agreement to be approved for listing on The Toronto Stock
Exchange, subject to official notice of issuance, prior to the Closing, and, if
such listing shall not have occurred prior to the Closing, Purchaser shall use
its reasonable best efforts to cause such shares to be listed on The Toronto
Stock Exchange within 90 days after the Closing.

                           (b)      Purchaser shall use its reasonable best
efforts to cause the Leitch Shares to be issued pursuant to this Agreement to be
approved for listing on The Nasdaq Stock Market as soon as reasonably
practicable after the Closing.

                           (c)      The Company shall use its reasonable best
efforts to cause the Form 10 to be declared effective by the SEC as soon as
reasonably practicable after the Closing.

                  4.8      COMPANY DISCLOSURE SCHEDULE. The Company shall
deliver to Purchaser the Company Disclosure Schedule no later than 5:00 P.M.
(San Diego time) on April 14, 2000. Purchaser shall notify the Company of (a)
its acceptance of the Company Disclosure Schedule or (b) its rejection of the
Company Disclosure Schedule, in any case, within three (3) Business Days after
receipt thereof, provided, however, that Purchaser may reject the Company
Disclosure Schedule only in accordance with Section 6.2(viii) hereof.

                  4.9      REGISTRATION RIGHTS. In the event that the Leitch
Shares are not freely tradeable after 40 days after the date of issuance of the
Leitch Shares to the Company and the Company has used its best efforts to ensure
that the assumptions described above in Section 2.23 at the time of resale are
correct and the Company has used its best efforts to comply with the
requirements as set out in the legend in section 2.24, the Company, upon written
notice to Purchaser, may require Purchaser to use its reasonable best efforts to
qualify all, but not less than all, of the Leitch Shares for distribution in
Ontario (the "Distribution"), subject to the following terms and conditions:

                           (a)      Purchaser will so qualify the Leitch Shares
for Distribution by way of a secondary offering only, or if Purchaser shall
determine in its sole discretion, by way of a primary offering and secondary
offering.

                           (b)      The Company agrees that it will comply with
all regulatory requirements in connection with the Distribution and agrees to
furnish to Purchaser and any underwriters all necessary, normal and customary
documents and information required in connection with the Distribution.

                           (c)      The rights of the Company to qualification
pursuant to this Section shall be conditioned upon the Company's participation
in any underwriting relating to the Distribution. The Company shall (together
with Purchaser) enter into an underwriting agreement in normal and customary
form with the underwriter or underwriters selected by Purchaser.

                                       19
<PAGE>

Notwithstanding any provision of this Section, if the underwriter, in its sole
discretion, determines that marketing factors require a limitation of the number
of securities to be underwritten, the underwriter may exclude some or all of the
Leitch Shares for which the Company seeks qualification from inclusion in the
Distribution. The Company may not request Purchaser qualify some or all of the
Leitch Shares excluded from the Distribution under this Section 4.9(c) more than
once in any 12 month period.

                           (d)      If Purchaser shall furnish to the Company, a
certificate signed by the Chief Executive Officer of Purchaser stating that, in
the good faith judgement of the board of directors of Purchaser, it would be
seriously detrimental to Purchaser and its shareholders for the Leitch Shares to
be qualified for Distribution and it its therefore in the best interests of
Purchaser to defer the qualification of the Leitch Shares, then Purchaser may
delay the qualification of the Leitch Shares, once but not more than once, for a
period not in excess of one hundred twenty (120) days.

                           (e)      Purchaser shall have no obligation under
this Section 4.9 to qualify for distribution any Leitch Shares if Purchaser
shall deliver to the Company an opinion of its Canadian counsel to the effect
that the proposed sale or disposition for which qualification was requested does
not require qualification under applicable Ontario laws.

                           (f)      The costs and expenses (other than
underwriting discounts or commissions and fees and disbursements of counsel of
the Company) relating to the Distribution, and of all other actions that
Purchaser is required to take or effect pursuant to this Section 4.9, shall be
paid by Purchaser.

                           (i)      by mutual written consent of Purchaser

                           (ii)     by either the Company or Purchaser, if
the Closing has not occurred by June 30, 2000 (provided that the right to

                           (v)      by Purchaser if:

                                    (A)      there shall have been a material
breach of any provision of Section 4.2;

Proposal or the Company has entered into an agreement with respect to a
Takeover Proposal.

and this Agreement shall forthwith become null and void, and there shall be
no liability on the part of Purchaser, the Company or their respective
directors, officers, employees, representatives, agents, advisors or
stockholders other than the obligations pursuant to this Section 7.2, except
that the agreements contained in Article IX hereof shall survive the
termination hereof. Nothing contained in this Section 7.2 or in Article VIII
shall relieve any party from liability for fraud or for willful breach of
this Agreement.

                                  ARTICLE VIII.
                                 INDEMNIFICATION

                  8.1      INDEMNITY. Subject to the terms and conditions of
this Article VIII, from and after the Closing, the Company shall indemnify
and hold harmless Purchaser from and against any and all Damages resulting
from or arising out of any misrepresentation, breach or failure of any
representation or warranty made by the Company in this Agreement; and (b)
subject to the terms and conditions of this Article VIII, from and after the
Closing, Purchaser shall indemnify and hold harmless the Company from and
against any and all Damages resulting from or arising out of any
misrepresentation, breach or failure of any representation or warranty made
by Purchaser in this Agreement.

                  8.2      LIMITATION ON INDEMNITY

                           (a)      Neither the Company nor Purchaser shall
have liability for amounts payable pursuant to their respective
indemnification obligations in this Article VIII until the total of all
Damages incurred by Purchaser or the Company, respectively, exceeds Two
Hundred and Fifty Thousand Dollars (U.S. $250,000) in the aggregate (the
"Threshold Amount"), after which the indemnification obligations of the
Company or Purchaser, as the case may be, shall, subject to subsection (b)
below, only include all such Damages in excess of the Threshold Amount.

                           (b)      Neither the Company nor Purchaser shall
have liability pursuant to its indemnification obligations in this Article
VIII to the extent that the total of all Damages suffered by Purchaser or the
Company, respectively, exceeds an aggregate of Ten Million Dollars
($10,000,000).

                  8.3      PROCEDURE. With respect to any Damages, whether a
claim, the commencement of any proceeding, any written demand, or the
occurrence of any other

                                       25
<PAGE>

similar event, any of which may constitute a separate matter or series of
matters ("Indemnification Matter") against which Purchaser or the Company (such
applicable party referred to as the "Indemnitee") is indemnified under this
Article VIII:

                           (a)      Within 30 days after the Indemnitee
receives written notice pertaining to the demand or proceeding underlying
such Indemnification Matter, or, if such Indemnification Matter does not
involve a third party demand or claim, within 30 days after the Indemnitee
first has actual knowledge of such Indemnification Matter, the Indemnitee
shall give notice to the Company or Purchaser, as the case may be, of the
nature of such Indemnification Matter and the amount demanded or claimed in
connection therewith. Such notice shall be a condition precedent to any
indemnification liability under this Article VIII, but the Indemnitee shall
not lose its right to indemnification other than under this Article VIII as a
result of the failure to give such notice in a timely manner.

                  8.4      REMEDIES. Notwithstanding anything in this
Agreement to the contrary, following the Closing, the rights of
indemnification under this Article VIII are the sole and exclusive remedy of
Purchaser or the Company, as the case may be, with respect to any and all
matters covered in Section 8.1 above, except that, notwithstanding the
foregoing and Section 8.5 below, Purchaser or the Company, as the case may
be, shall be entitled to all remedies which are available under Applicable
Law for fraudulent conduct and under Section 10(b) of the Exchange Act and
the rules and regulations of the SEC thereunder.

                  8.5      TIME LIMIT. Damages to be indemnified under this
Article VIII must be claimed within one year after the Closing, except for
Damages resulting from or arising out of Indemnification Matters for which
proper notice under Section 8.3 above shall have been given prior to the
expiration of such one-year period.

                                  ARTICLE IX.
                            MISCELLANEOUS AND GENERAL

                  9.1      PAYMENT OF EXPENSES AND OTHER PAYMENTS.. All fees
and expenses incurred in connection with this Agreement and the Transactions
shall be paid by the party incurring such fees or expenses, whether or not
the Transactions are consummated.

                  9.2      SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The
representations and warranties made herein shall not survive beyond the
