Dear Ramon:

Sorry for the delay. I am committed to supplying Grifols with *** liters of
plasma in calendar year 2001 and I continue to believe that the current
plasma price for delivery in 2001 is US *** per liter (non-pcr tested);
however, I would like to propose the following:

     Base Price per liter = US ***
     30 day inventory hold
     payment 30 days from date of shipment

Pricing adjustment: using a base Euro/Dollar exchange rate of .855, for every
5% improvement in the Euro against the dollar exchange rate the price would
increase by US $.50 adjusted quarterly.

If you have any questions, I will be in the office the rest of the week.

Best regards,

/s/ Barry

From:
Ramon Riera             Subject: Your fax of November 6, 2000

Dear Barry:

I acknowledge receipt with thanks of your fax of November 06 in which you
state your final offer for *** liters of plasma for calendar year 2001 at
USDL. ***/liter.

In this regard, I confirm that we have decided to accept your quotation
although it involves an important increase in costs and furthermore the
current exchange rate between USDL. and euro entails an unfavourable
situation. Nevertheless, we appreciate your efforts and understand that your
final proposal is reasonable under the current circumstances and, therefore,
acceptable.

On the other hand, we assume that further discussions concerning additional
quantities of plasma are postponed.

Finally, we would like to thank you for your continued willingness and
collaboration.

Best regards,
GRUPO GRIFOLS, S.A.

1    DISTRIBUTION AGREEMENT DECLARATIONS

     THIS AGREEMENT is made and entered into on this 15th day of March by and
     between HPL INC., a corporation organized and existing under the laws of
     the UNITED STATES OF AMERICA with its principal place of business at
     2033 GATEWAY PLACE, SAN JOSE, CA 95110 (hereafter "Supplier") and CANON
     SALES CO., INC., a corporation organized and existing under the laws of
     Japan, with its principal place of business at 22-12-23, KONAN,
     MINATO-KU, TOKYO 108-0075, JAPAN (hereafter "Distributor").

     WHEREAS, Supplier is the owner of certain computer programs and is the
     provider of related service Products, for use in the semiconductor
     industry (the "Products"), which Products are more particularly described
     in Exhibit A attached hereto; and wishes to expand its market for the
     Products in the geographical areas (the "Territories") set forth in
     Exhibit B attached hereto;

     WHEREAS, Supplier wishes to appoint Distributor and Distributor wishes
     to accept such appointment, as the independent, exclusive (except for
     possible direct OEM customers of supplier as described herein)
     distributor of the Products in the Territories on the terms and
     conditions set forth herein; and

     WHEREAS, Distributor wishes to assign this Agreement to those of its
     subsidiaries and affiliates in the respective Territories more
     particularly described in Exhibit B attached hereto and Supplier
     acknowledges the benefits of that assignment.

     NOW, THEREFORE, Supplier and Distributor agree as follows:

2    APPOINTMENT OF DISTRIBUTOR; TERMS OF PRODUCT AND SERVICES SALES

2.1  Appointment and Exclusive Right

     Subject to all of the terms and conditions of this Agreement, Supplier
     hereby appoints Distributor, and Distributor hereby accepts such
     appointment, an exclusive right to solicit and collect orders for
     licensed use of the Products by others ("Licensed Users") within the
     Territories. Said exclusivity, however, shall not apply to sale to and
     licensed use of the Products by customers of Supplier OEM customers,
     which sell Product use licenses as standard or optional elements of
     either hardware or software Products under an OEM agreement with
     Supplier. An OEM (Original Equipment Manufacturer) is defined as an
     entity that purchases products and incorporates them into their own
     products. For example, HP bundles Supplier's BitMapView with their
     Agilent Versatest Series.

2.2  Limited Agent Authority of Distributor

     Distributor shall hold itself out to customers only as a limited agent
     of Supplier. Distributor shall have no authority to accept on behalf of
     Supplier any offer except as provided herein. Distributor shall make no
     warranties with respect to the Products which exceed the Warranties made
     by Supplier, except as by written agreement by Supplier.

2.3  Supplier Obligations Regarding Customers in Territories Assigned to
     Distributor

     Supplier shall not sell the Products directly to end-use customers in
     the Territories. Supplier shall refer to Distributor, within two weeks,
     all orders and inquiries relating to the Products

[*]  CERTAIN INFORMATION IN THIS EXHIBIT HAS BEEN OMITTED AND FILED
SEPARATELY WITH THE COMMISSION. CONFIDENTIAL TREATMENT HAS BEEN REQUESTED WITH
RESPECT TO THE OMITTED PORTIONS.

                                                                       Page 5
<PAGE>

     originating from within or outside the Territories to the extent such
     orders or inquiries relate to Products destined for use within the
     Territories.

2.4  Limitations Regarding Customers Outside Territories Assigned to Distributor

     Distributor shall not sell the Products directly to customers outside
     the Territories and shall refer to Supplier within two weeks all orders
     and inquiries relating to the Products originating from within or
     outside the Territories to the extent such orders or inquiries relate to
     Products destined for use outside the Territories. In the event of
     purchase of Products by customer inside the Territories for use outside
     the Territories Distributor will be compensated for sales process
     portion of the sales as specified in Exhibit E.

2.5  Limitations on Products Purchased Outside Territories

     In any License Agreements outside the Territories subsequent to the date
     of this Agreement, Supplier will require that the Products purchased
     elsewhere may not be installed within the Territories of this Agreement
     without appropriate compensation to Distributor as provided in Exhibit E.

2.6  Supplier Obligations Regarding Distribution Conflict

     In negotiation or renegotiations of any agreement with any of its other
     distributors, agents or employees subsequent to the date of this
     Agreement, Supplier will insist upon a covenant that such other
     distributor, agent or employee will not seek customers or establish a
     branch or maintain any distribution outlet in conflict with the terms of
     this Agreement during the term of this Agreement.

2.7  Product Rights and Restrictions

     Distributor recognizes and agrees that the Products and all
     reproductions thereof, or any parts hereof, including all translations
     and derivatives, are and shall be the exclusive and confidential
     property and trade secrets of Supplier. Distributor may not alter the
     Products without the prior written permission of Supplier. Neither the
     Products nor any parts thereof shall be copied or modified by
     Distributor for any purpose outside the scope of this Agreement.

2.8  Transfer Price

     The Transfer Price paid by Distributor to Supplier for Products,
     licenses and services shall be determined by standard discount terms
     applied as a function of customer purchase order price (for standard
     software Products) as compared to the suggested international list
     prices published by Supplier as described in Exhibit A. Supplier
     Suggested International List Prices shall generally apply and discount
     terms to Distributor shall be reviewed and considered for adjustment as
     described in Exhibit A. Supplier may make changes to its Supplier
     Suggested International List Price schedule at any time upon 30 days
     written notice to Distributor. However, outstanding customer quotations
     based upon the price list in effect prior to a price change shall be
     honored for up to 90 days from the date of notice of the price change.

                                                                       Page 6
<PAGE>

2.9  Distributor Pricing to Customers in the Territories

     Prices charged customers for standard Products sold by Distributor in
     the Territories shall be at the discretion of Distributor. Price
     quotations shall include, in addition to prices for standard Product
     software licenses all Distributor and Supplier Support costs not
     otherwise quoted as a separate line item for the customer. All support
     services required by Distributor on behalf of the licensed customer
     shall be the financial responsibility of the Distributor except as
     otherwise noted and agreed by Supplier and Distributor in writing in
     conjunction with specific customer cases.

2.10 Payment Collection

     Distributor shall collect full payment for the orders received and will
     pay Supplier the Supplier's portion in US Dollars, as set out in Exhibit
     A attached hereto. Distributor agrees to pay Supplier portion in
     electronic transfer within 30 days of shipment of Product to Distributor.

2.11 Tax Collection and Tax Payment Responsibilities of Distributor

     All orders quoted by Distributor shall include value added tax (V.A.T.)
     as required by the local government as well as any and all import and/or
     export taxes levied by any government which imposes taxes on the
     transaction or shipment and delivery processes. The responsibility for
     collecting these taxes and any other local taxes or duties imposed, and
     the subsequent payment to the government responsible for the taxation
     belongs entirely with Distributor, and Supplier will in no way be
     involved with this process or liable for any unpaid taxes. Appropriate
     uplift of prices quoted and charged customers above the "International
     Price" in order to cover all taxes imposed is the sole responsibility of
     the Distributor. "International Prices" provided by Supplier are to be
     always taken as exclusive of all taxes.

2.12 New Products Notification and Information to Distributor

     Supplier shall provide written notice of any new Product to be released.
     Supplier will provide sufficient information to update Product (as
     described in Exhibit A) and price lists and will not unreasonably
     withhold agreement on such changes as reflected in updated Distributor
     Pricing Schedule. Updated Product price list will be sent to Distributor
     the earlier of the following two scenarios: market conditions change
     significantly or quarterly (every 3 months). Product price list is an
     addendum and should not be part of the Distributor Agreement.

2.13 Notification, Information and Support Regarding Products Withdrawn

     Supplier shall provide written notice of any Product to be withdrawn
     from Supplier's Marketing Program. Supplier shall maintain support for
     said withdrawn Product for three years following the effective date of
     withdrawal from marketing, provided the customer has maintained an
     on-going service and maintenance agreement with Distributor on an
     uninterrupted basis.

2.14 Purchase Orders

     Purchase orders from the customer for the Products in the Territories
     are to be addressed to Distributor. Distributor shall in turn place a
     purchase order with Supplier for the amount of the Supplier's portion,
     and Supplier will ship the Products to the Distributor except as

     on an annualized basis with details enumerated for one year out and
     generalized trends and goals for the second and third year of the three
     year planning period. In addition, the detailed annual plans are

                      EXHIBIT A. STANDARD PRODUCTS PRICING

A_1. SUPPLIER SUGGESTED INTERNATIONAL LIST PRICES AND DISTRIBUTOR DISCOUNTS

Supplier shall provide Distributor with a price list specifying the Suggested
International List Price of licenses to utilize its Products. In addition,
Supplier shall provide guidelines as to pricing for support services (such as
mandatory first year technical support, premium levels of technical support,
data integration and installation) and its support Products (turnkey
services, paid evaluations, etc.).

Supplier shall assist Distributor in preparation of Customer price quotations
as required. Distributor may request that quotations for a given set of
customer requirements be prepared by Supplier or Distributor may prepare a
proposed customer quotation and request that Supplier sales support or
marketing personnel check and validate the quotation in question. Negotiation
appropriate to assure the sale, meet competitive challenges and set discount
or other incentives in place shall be the joint responsibility of the
Supplier and Distributor.

Subject to the foregoing, the wholesale price paid for Product or license
fees by Distributor will be calculated according to the end customer purchase
order price and the suggested international list price (SILP) as follows:

<TABLE>
<CAPTION>
             CUSTOMER PURCHASE
                ORDER PRICE                    DISCOUNT TO SUPPLIER
             -----------------                 --------------------
             <S>                               <C>
             SILP+[***]% or more               [***]%
             SILP-[***]% to SILP+[***]%        [***]%
             (SILP-[***]%) to (SILP-[***]%)    [***]%
             Less than (SILP-[***]%)           Negotiated and only by written agreement
</TABLE>

Generally, discounts (if any) which are made available to customers are
applicable to software license fees only. Discounts specifically shall not
apply to support programs, data integration, installation, custom software
development, or hardware. Distributor discounts for support Products and
services are to be specified in the Support Plan for the Territories to be
completed as specified in Exhibit C. All prices provided to Distributor by
Supplier shall be in constant US Dollars.

A_2. PLAN AND PROCESS FOR REVIEW AND REVISION OF PRICING.

Pricing reviews will take place on an annual basis or as mutually agreed to
by the Companies. In the event of a market or business stimulus judged to
require pricing action according to the judgment of either company, a written
request and proposal for pricing review shall be made to the other company
and such request shall be reasonably honored. In the event that pricing
consistent with the current transfer price is not appropriate to the
prevailing competitive environment, the parties will meet to discuss revised
pricing. The principle shall be that if gross margin is reduced in response
to a competitive situation, the parties share the reduction.

evaluation, sale, installation and post-installation support may be spread
across territorial boundaries and shared among multiple distribution and
support partners. In such an event, the terms of revenue sharing should be
agreed among all partners in writing. However, the general approach for split
of software license revenue credit among distributors shall proceed along the
following guidelines:

<TABLE>
<S>                                                             <C>
Original Product sales presentations and demonstrations         [***]%

Secondary, localized Product sales and presentations process    [***]%
</TABLE>

(In the event that both processes are deemed equal in magnitude and decision
impact a total of 30% shall be split evenly between the distributors).

<TABLE>
<S>                                                             <C>
Customer Order Submittal Support and Acceptance Processing      [***]%
Including Development of Acceptance Criteria and Payment
Terms and Conditions

Local Installation and Acceptance                               [***]%

On-going Warranty, Maintenance and Application Support          [***]%
</TABLE>

Revenue for services, support and hardware generally will be credited to the
Distributor in the territory in which the Supplier software is installed
except as otherwise specified by written agreement among Supplier and
Distributors involved in the multi-national transaction. Supplier vs.
Distributors portions of this revenue shall be governed by the discount price
structure defined in Exhibit A.
