"Path 1 Class A Common Stock"), of the Company (all such 1,250,000 shares of
Path 1 Class A Common Stock being hereinafter referred to as the "Path 1
Shares") and the Company desires to sell all of the Path 1 Shares to Purchaser,
on the terms and subject to the conditions hereinafter set forth.

                  NOW, THEREFORE, in consideration of the foregoing and the
respective representations, warranties, covenants and agreements set forth
herein, the parties hereto agree as follows:

                                   ARTICLE I
                     PURCHASE AND SALE OF THE PATH 1 SHARES

                  1.1      PURCHASE AND SALE OF THE PATH 1 SHARES. Subject to
the terms and conditions of this Agreement and on the basis of the
representations, warranties, covenants and agreements herein contained, at the
Closing (as hereinafter defined), the Company agrees to sell, assign and convey

                  The Company hereby represents and warrants to Purchaser as

<PAGE>

                  2.1      ORGANIZATION AND QUALIFICATION; COMPANY SUBSIDIARIES.
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
business as a foreign corporation in all jurisdictions wherein it is required to

Company Material Adverse Effect. The Company does not have any subsidiaries
other than as set forth in Section 2.1 of the disclosure schedule delivered to
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, directly or indirectly, in any corporation, association,

is the Company bound by any agreement to acquire any such 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)
10,000,000 shares of Path 1 Class B Common Stock, of which, as of the date

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

employees or consultants of the Company, there are no outstanding options,
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

                  2.4      REPORTS; FINANCIAL STATEMENTS; UNDISCLOSED
LIABILITIES.

                           (a)      On March 23, 2000, the Company re-filed a
General Form for Registration of Securities on Form 10 (the "Form 10") with the
Securities and Exchange Commission (the "SEC") pursuant to the Securities
Exchange Act of 1934, as amended (the "Exchange Act"). On the re-filing date,
the Form 10 complied in all material respects with the applicable requirements
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
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading.

                           (b)      On the filing date, the financial statements
(including the related notes thereto) of the Company included in the Form 10
complied in all material respects with applicable accounting requirements and
the published rules and regulations of the SEC with respect thereto, were
prepared in conformity with generally accepted accounting principles ("GAAP")
applied on a consistent basis during the periods involved (except as otherwise
noted therein) and presented fairly in all material respects the financial
position of the Company as of their respective dates, and the results of its
operations and cash flows for the periods presented therein (subject, in the
case of the unaudited interim financial statements, to normal year-end
adjustments). As of the date of the Company's most recent regularly prepared
consolidated balance sheet, the Company had less than $10,000,000 of
consolidated total assets.

                           (c)      Except (i) as set forth in Section 2.4(c) of
the Company Disclosure Schedule, (ii) as set forth in the balance sheet of the
Company as of December 31, 1999 set forth in the Form 10 (the "Balance Sheet")
and (iii) for current liabilities and obligations incurred in the ordinary
course of business consistent with past practice since December 31, 1999 (and
not materially different in type or amount), the Company does not have 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.

                  2.5      ISSUANCE OF PATH 1 SHARES. When issued, sold and
delivered to Purchaser in accordance with the terms of this Agreement for the
consideration expressed herein, the Path 1 Shares shall be duly and validly
authorized, fully paid and non-assessable shares of Path 1 Class A Common Stock
free and clear of any restrictions on transfer, other than restrictions on
transfer under the Stockholders' Agreement or applicable state, foreign and
federal securities laws, and free and clear of any preemptive or similar rights.

                  2.6      ABSENCE OF CERTAIN CHANGES. Since the date of the
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
events or changes having, or reasonably likely to have, individually or in the
aggregate, a Company Material Adverse Effect.

from any taxing authority of any deficiency, claim or other dispute relating to
the payment or assessment of any Taxes for any period which remains unsettled at
the date hereof.

Disclosure Schedule, the Company enjoys peaceful and undisturbed possession
under all leases under which it is the lessee, and all said leases are valid and
subsisting and in full force and effect, except with respect to Permitted Liens,
or as could not reasonably be expected to have a Company Material Adverse
Effect.

                  2.9      TITLE TO ASSETS. Except as set forth in Section 2.9
of the Company Disclosure Schedule, the Company has good and merchantable title
to all of the properties and assets (tangible and intangible) which it owns and

properties and assets which it leases, licenses or uses in the operation of its
business as currently conducted, in any case, free and clear of all Liens,
except for Permitted Liens, or as could not reasonably be expected to have a
Company Material Adverse Effect.

any federal, state or foreign securities laws (all of which will be made or
obtained on or prior to the Closing) and except as set forth in Section 2.17 of
the Company Disclosure Schedule, no consents, approvals or authorizations of, or

enforceability is considered in a proceeding in equity or at law) and (iii) as

which it was made, in order to make the statements herein or therein not
misleading.

                  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

Purchaser.

                           (c)      The Company understands that, under the
existing rules of the SEC, the Company may be unable to sell the Leitch Shares
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
such sale pursuant to the Securities Act and applicable state securities laws or
an applicable exemption therefrom or (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 under the Securities Act
("Rule 144") or (iv) outside the United States in compliance with the
requirements of Rule 904 of Regulation S under the Securities Act ("Rule 904").

                           (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

                  transaction or part of a series of transactions which,
                  although in technical compliance with Regulation S, is part of
                  a plan or scheme to evade the registration requirements of the
                  Securities Act. Terms used herein have the meanings given to
                  them by Regulation S."

                                  ARTICLE III.

Incorporation or By-laws of Purchaser or (b) subject to receipt of regulatory
approvals and required filings under federal, state and provincial securities

Purchaser consists of: (i) an unlimited number of shares of Leitch Common
Shares, of which, as of the date hereof, 25,071,573 shares of Leitch Common

interim financial statements, to normal year-end adjustments).

                  3.5      ISSUANCE OF LEITCH SHARES. When issued, sold and
delivered in accordance with the terms of this Agreement for the consideration
expressed herein to the Company, the Leitch Shares shall be duly and validly

Stock Market to list the Leitch Common Shares thereon.

as are required under the Ontario Business Corporations Act and Canadian
securities laws, no consents, approvals or authorizations of, or filings with,
any Governmental Authority or any other person or entity are required in
connection with the execution and delivery of this Agreement by Purchaser and
the consummation of the Transactions contemplated hereby to be consummated by
Purchaser, except where the failure to obtain such consents, approvals, or
authorizations, or make such filings, would not have a Purchaser Material
Adverse Effect.

                  3.7      AUTHORITY. Purchaser has the requisite corporate
power and authority to execute and deliver this Agreement and to consummate the
Transactions. The execution, delivery and performance of this Agreement and the

this Agreement are hereinafter referred to as the "Purchaser Disclosure

Purchaser Disclosure Documents complied in all material respects with the

Purchaser in this Agreement and no statement by Purchaser contained in any
exhibit, disclosure schedule, or certificate contemplated by this Agreement

                  4.2      ALTERNATIVE PROPOSALS.

encourage, or initiate discussions or negotiations with, or provide any
information to, any Person (other than Purchaser, any of its Affiliates or

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,

advice from


                                       16

Proposal, or enter into any letter of interest, agreement or other arrangement

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

any proposal, discussion, negotiation or inquiry received by the Company
regarding any Takeover Proposal, and the Company will promptly communicate to

negotiation or inquiry) regarding any Takeover Proposal and the identity of the
party making such proposal or inquiry or engaging in such discussion or

information concerning the Company provided to any other Person which was not
previously provided to Purchaser. The Company will keep Purchaser informed of

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

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

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

communication from any

<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

release or other announcement with respect to this Agreement or the other
Transactions without prior consultation with the other parties, except in order

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

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

<PAGE>

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

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

                  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

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.

                  7.1      TERMINATION. This Agreement may be terminated and
the Transactions contemplated hereby may be abandoned at any time prior to
the Closing:

                           (i)      by mutual written consent of Purchaser
and the Company;

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

                           (iii)    by either the Company or Purchaser, if
there shall be any Applicable Law that makes consummation of the Transactions

decree shall become final and nonappealable;

                           (iv)     by either the Company or Purchaser, if
there has been a breach by the other party of any representation or warranty

                           (v)      by Purchaser if:

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

                                    (B)      any Person or "group" (within

                               (C)      if the Company receives a Takeover

Proposal after a reasonable amount of time (and in no event more than ten
Business Days following such receipt) has elapsed for the Company's Board of
Directors to review and make a recommendation with respect to such Takeover
Proposal or the Company has entered into an agreement with respect to a
Takeover Proposal.

                  7.2      EFFECT OF TERMINATION. In the event of the
termination of this Agreement as provided in Section 7.1 hereof, written
notice thereof shall forthwith be given to the other party or parties
specifying the provision hereof pursuant to which such termination is made,
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
earlier of termination of this Agreement, subject to Section 8.5 above, or
one year from the date of Closing. This Section 9.2 shall not limit any
covenant or agreement of the parties hereto which by its terms contemplates
performance after the Closing.

                  9.3      MODIFICATION OR AMENDMENT. Subject to the
compliance with Applicable Law, at any time prior to the Closing, the parties
hereto may modify or amend this Agreement, by written agreement executed and
delivered by duly authorized officers of the respective parties.

                  9.4      WAIVER OF CONDITIONS. Except as otherwise provided
in this Agreement, any failure of any of the parties to comply with any
obligation, covenant, agreement or condition herein may be waived by the
party or parties entitled to the benefits thereof only by a written


                                       26
<PAGE>

instrument signed by the party granting such waiver, but such waiver or
failure to insist upon strict compliance with such obligation, covenant,
agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure.

                  9.5      COUNTERPARTS. This Agreement may be executed in
two or more counterparts, all of which shall be considered one and the same
agreement and shall become effective when two or more counterparts have been
signed by each of the parties (including by telecopy) and delivered to the
other parties, it being understood that all parties need not sign the same
counterpart.

                  9.6      GOVERNING LAW. This Agreement shall be governed
by, and construed in accordance with, the laws of the State of Delaware
without giving effect to the principles of conflicts of law thereof.

                  9.7      JURISDICTION; WAIVER OF TRIAL BY JURY. THE PARTIES

PROCEEDING IN SUCH STATE ON THE BASIS OF FORUM NON CONVENIENS. THE PARTIES
FURTHER AGREE THAT ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO
THIS AGREEMENT SHALL BE BROUGHT ONLY IN A NEW YORK STATE OR UNITED STATES
FEDERAL COURT SITTING IN NEW YORK COUNTY.
