     option exercises are dependent on the future performance of the Company,
     overall market conditions and the optionees' continued employment through
     the vesting period. The amounts reflected in this table may not be
     achieved.

(2)  The Company granted options to purchase an aggregate of 698,803 shares of
     Common Stock during the year.

(3)  All options were granted at an exercise price equal to the fair market
     value of the Common Stock on the date of grant.

(4)  The option is fully exercisable from the date of grant, subject to the
     Company's right to repurchase any unvested shares at the original purchase
     price upon the optionee's termination as an employee. The shares vests in
     48 equal monthly installments from the date of grant.

     Market on December 31, 1999, less the exercise price.

(2)  All options are fully exercisable, subject to the Company's right to

     thereof) vest over a period of four years from the date of grant.

COMPENSATION OF DIRECTORS

         Directors receive quarterly fees of $3,000 as compensation for their
services as members of the Board of Directors. In addition, directors receive
fees of $500 for each Board or committee meeting attended.

         The Company's 1995 Outside Directors Stock Option Plan (the "Directors
Plan") provides for formula-based grants of options to non-employee directors.
Under the Directors Plan, each non-employee director of the Company is
automatically granted a nonstatutory stock option to purchase 20,000 shares of
Common Stock (an "Initial Option") on the date on which such person first
becomes a non-employee director of the Company. Thereafter, on the date
immediately following each annual stockholders' meeting, each non-employee
director who is reelected at the meeting to an additional term is granted an
additional option to purchase 4,800 shares of Common Stock (an "Annual Option")
if, on such date, he has served on the Board of Directors for at least six
months. The Directors Plan provides that each Initial Option shall become
exercisable in installments as to one-fourth of the total number shares subject
to the option on each of the first, second, third and fourth anniversaries of
the date of grant, and each Annual Option shall become exercisable in full one
year after the date of grant, subject to the director's continuous service. The
exercise price per share of all options granted under the Directors Plan shall
be equal to the fair market value of a share of the Company's Common Stock on
the date of grant. Options granted under the Directors Plan have a term of ten
years.

(1)  Beneficial ownership is determined in accordance with the rules of the
     Securities and Exchange Commission. In computing the number of shares
     beneficially owned by a person and the percentage ownership of that person,
     shares of Common Stock subject to options or warrants held by that person
     that are currently exercisable, or will become exercisable within 60 days
     after March 31, 2000, are deemed outstanding. Such shares, however, are not
     deemed outstanding for purposes of computing the percentage ownership of
     any other person. In general, options granted under the 1993 Stock Option
     Plan are fully exercisable from the date of grant, subject to the Company's
     right to repurchase any unvested shares at the original exercise price in
     the event of termination of the optionee's employment. Unless otherwise
     indicated in the footnotes to this table, the persons and entities named in
     the table have sole voting and sole investment power with respect to all
     shares beneficially owned, subject to community property laws where
     applicable.

ITEM 13.      CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         We have entered into the transactions and arrangements with Oren
Semiconductor, Inc. described below. Oren was a subsidiary of ours until January
1996, when it was spun off to our stockholders. Elron Electronics Industries
Ltd., our largest stockholder, and The Israel Corporation, which until recently
was a beneficial owner of more than 5% of our outstanding shares of common
stock, are each principal stockholders of Oren. Additionally, several of our
directors are stockholders of Oren and two of our directors, Levy Gerzberg and
Uzia Galil, are also members of Oren's board of directors.

EXPENSES INCURRED ON BEHALF OF OREN

         From the time of the spin-off through September 1998, we advanced a
substantial portion of Oren's operating expenses related to its operations in
the United States, all of which were later reimbursed by Oren. These expenses
included payroll, employee benefits, professional fees and other operating
expenses. Until September 1997, we permitted Oren to occupy a portion of our
Santa Clara facility, for which Oren reimbursed us for a pro rata portion of our
monthly facility cost. Since October 1998, we have shared our facility in Japan
with Oren, in return for which Oren reimburses us for total operating cost
related to that facility. The expenses we incurred on Oren's behalf during the
years ended December 31, 1997, 1998 and 1999 were $405,000, $403,000 and
$146,000.

TECHNOLOGY LICENSE AGREEMENT

         In March 1999, we entered into a technology license agreement with
Oren pursuant to which we granted Oren a worldwide nonexclusive license to
incorporate a Zoran video decoder core in products sold by Oren to end users,
resellers and original equipment manufacturers and to incorporate our core
into Oren's own cores for license to third parties. The license agreement
grants Oren similar rights to any updates to our core that we develop or
release within one year after the date of the agreement. In return for this
license, Oren agreed to pay us nonrefundable license and maintenance fees
totaling $400,000, of which $200,000 has been paid to date. Oren also agreed
to pay us royalties and maintenance fees, based on the number of units
incorporating our core that are sold by Oren or by licensees of its cores,
and additional royalties based on any nonrefundable fee paid to Oren for the
license of any core that incorporates the core we licensed to Oren. To date,
Oren has not paid any royalties or related maintenance fees. The initial term
of the license agreement is two years, and it will be automatically renewed
for three additional one-year terms unless either party elects otherwise at
least 30 days prior to a renewal date. The agreement may be terminated by
either party in the event of a material breach by the other party or by us in
the event of Oren's insolvency. The terms of the license agreement are
comparable to similar agreements that we have entered into with unrelated
third parties based on arm's-length negotiations.

SHORT-TERM LOAN

         In April 1999, we made a loan of $350,000 to Oren. The loan bore simple
interest at the rate of 7% per year and had a term of three months. The loan was
repaid in full in July 1999.
