2.       OPLINK'S RIGHTS AND OBLIGATIONS

(a)      PROMOTIONAL MATERIAL. Oplink shall be responsible for supplying

         event of an increase, the new products are not competitive with the
         other products then represented by Representative, (ii) in the event of
         a decrease, such decrease does not affect any of Oplink's outstanding
         obligation of delivery. Notwithstanding the foregoing, Representative
         may decline to sell any new products by so notifying Oplink in writing
         within twenty (20) days of receiving notice of product increase

         copy of such written notice shall be transmitted to Representative at
         the same time.

3.       REPRESENTATIVE'S RIGHTS AND OBLIGATIONS

(a)      REPRESENTATIVE'S OWN COST. The Representative shall pay all of its
         sales expenses, including any expense of its sub-agents, incurred in
         connection with the representation as herein contemplated.

(b)      RETURNS. Representative shall only, on behalf of Oplink, accept the
         return of Products, or make allowances with respect thereto, with the
         prior written approval of Oplink.

(c)      PERFORMANCE. Unless otherwise agreed in writing, Representative shall
         procure the annual target numbers of orders for Oplink as set forth in
         Exhibit C (the "Targets"). Failure to do so shall entitle Oplink to, at
         its sole discretion, convert Representative's exclusive status to
         non-exclusive or terminate this Agreement.

4.       COMMISSIONS:

(a)      CALCULATION. Oplink shall pay Representative a commission based on the
         total of the "net invoice price" of all commissionable orders received
         from the Territory. Such commission is fixed at the rate of 5%, which
         will remain until March 31, 2002.

(b)      DEFINITION OF NET INVOICE PRICE. The term "net invoice price" shall
         mean the price at which the Products are actually sold to the customer
         after excluding all shipping costs and any other allowances expressly
         granted to the customer by Oplink including, but not limited to, taxes,
         discounts, and insurance.

(c)      SPLIT OF COMMISSION. The parties recognize that sometimes the
         engineering jurisdiction and the ship to location are in different
         territories. In such cases, a 50/50 split commission will apply. In any
         territory where Oplink does not have a sales representative or
         distributor, Oplink shall be considered to be such sales representative
         or distributor with respect to commissions.

(d)      PAYMENT. Commissions are due and payable on or before the fifteenth
         (15th) day of the month following the month in which Oplink received
         payment from the customer.

5.       REPRESENTATIVE PERFORMING CONSIGNMENT FUNCTION

Oplink, in discussion with Representative, will together determine from time to
time if and when Representative will perform a consignment function.
Representative will agree to perform a consignment function for the sole purpose
of expediting delivery of a particular customer's product requirements as
governed by a blanket purchase order between Oplink and the customer. In such
circumstances, "consignment" shall be limited to holding Products on Oplink's
behalf, with Oplink retaining title, authority and exclusive control over such
Products(s). Representative shall only release such Products upon Oplink's
written authorization. Under no circumstance does Representative performing such
a consignment function for Oplink constitute a principal distributor
relationship.
