Enrollment Date shall be eligible to participate in the Plan.

            (b) Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) to the extent that,
immediately after the grant, such Employee (or any other person whose stock
would be attributed to such Employee pursuant to Section 424(d) of the Code)
would own capital stock of the Company and/or hold outstanding options to
purchase such stock possessing five percent (5%) or more of the total combined
voting power or value of all classes of the capital stock of the Company or of
any Subsidiary, or (ii) to the extent that his or her rights to purchase stock

accrues at a rate which exceeds Twenty-Five Thousand Dollars ($25,000) worth of
stock (determined at the fair market value of the shares at the time such option
is granted) for each calendar year in which such option is outstanding at any
time.

        4. Offering Periods. The Plan shall be implemented by consecutive
Offering Periods with a new Offering Period commencing on the first Trading Day
on or after May 15 and November 15 each year, or on such other date as the Board
shall determine, and continuing thereafter until terminated in accordance with
Section 20 hereof; provided, however, that the first Offering Period under the
Plan shall commence with the first Trading Day on or after the date on which the
Securities and Exchange Commission declares the Company's Registration Statement
effective and ending on the last Trading Day on or before May 14, 2001. The
Board shall have the power to change the duration of Offering Periods (including
the commencement dates thereof) with respect to future offerings without
stockholder approval if such change is announced at least five (5) days prior to
the scheduled beginning of the first Offering Period to be affected thereafter.

        5. Participation.

            (a) An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
of Exhibit A to this Plan and filing it with the Company's payroll office prior
to the applicable Enrollment Date.

            (b) Payroll deductions for a participant shall commence on the first
payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

        6. Payroll Deductions.

            (a) At the time a participant files his or her subscription
agreement, he or she shall elect to have payroll deductions made on each pay day

Compensation which he or she receives on each pay day during the Offering
Period.

            (b) All payroll deductions made for a participant shall be credited
to his or her account under the Plan and shall be withheld in whole percentages
only. A participant may not make any additional payments into such account.

                                      -3-
<PAGE>   4

            (c) A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions during the Offering Period by completing or filing
with the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

            (d) Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to zero percent (0%) at any time during an
Offering Period. Payroll deductions shall recommence at the rate provided in
such participant's subscription agreement at the beginning of the first Offering
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10 hereof.

            (e) At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

        7. Grant of Option. On the Enrollment Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase on the Exercise Date of such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Offering Period more than 3,000
shares (subject to any adjustment pursuant to Section 19), and provided further
that such purchase shall be subject to the limitations set forth in Sections
3(b) and 12 hereof. Exercise of the option shall occur as provided in Section 8
hereof, unless the participant has withdrawn pursuant to Section 10 hereof. The
Option shall expire on the last day of the Offering Period.

        8. Exercise of Option. Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Offering Period, subject to earlier withdrawal by the participant as provided in
Section 10 hereof. Any other monies left over in a participant's account

                                      -4-
<PAGE>   5

after the Exercise Date shall be returned to the participant. During a
participant's lifetime, a participant's option to purchase shares hereunder is
exercisable only by him or her.

        9. Delivery. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, the shares purchased upon exercise of his or
her option.

        10. Withdrawal.

            (a) A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company in
the form of Exhibit B to this Plan. All of the participant's payroll deductions
credited to his or her account shall be paid to such participant promptly after
receipt of notice of withdrawal and such participant's option for the Offering
Period shall be automatically terminated, and no further payroll deductions for
the purchase of shares shall be made for such Offering Period. If a participant
withdraws from an Offering Period, payroll deductions shall not resume at the
beginning of the succeeding Offering Period unless the participant delivers to
the Company a new subscription agreement.

            (b) A participant's withdrawal from an Offering Period shall not
have any effect upon his or her eligibility to participate in any similar plan
which may hereafter be adopted by the Company or in succeeding Offering Periods
which commence after the termination of the Offering Period from which the
participant withdraws.

        11. Termination of Employment. Upon a participant's ceasing to be an
Employee for any reason, he or she shall be deemed to have elected to withdraw
from the Plan and the payroll deductions credited to such participant's account
during the Offering Period but not yet used to exercise the option shall be
returned to such participant or, in the case of his or her death, to the person
or persons entitled thereto under Section 15 hereof, and such participant's
option shall be automatically terminated. The preceding sentence
notwithstanding, a participant who receives payment in lieu of notice of
termination of employment shall be treated as continuing to be an Employee for
the participant's customary number of hours per week of employment during the
period in which the participant is subject to such payment in lieu of notice.

        12. Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

        13. Stock.

            (a) Subject to adjustment upon changes in capitalization of the
Company as provided in Section 19 hereof, the maximum number of shares of the
Company's Common Stock which shall be made available for sale under the Plan
shall be 300,000 shares, plus an annual increase to be added on the first day of
the Company's fiscal year beginning in 2001 equal to the lesser of (i) 400,000
shares, (ii) 1% of the outstanding shares on such date, or (iii) a lesser amount
determined by the Board. If, on a given Exercise Date, the number of shares with
respect to which options are to be exercised exceeds the number of shares then
available under the Plan, the Company shall make a pro rata allocation of the
shares remaining available for purchase in as uniform a manner as shall be
practicable and as it shall determine to be equitable.

                                      -5-
<PAGE>   6

            (b) The participant shall have no interest or voting right in shares
covered by his option until such option has been exercised.

            (c) Shares to be delivered to a participant under the Plan shall be
registered in the name of the participant or in the name of the participant and
his or her spouse.

        14. Administration. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

        15. Designation of Beneficiary.

            (a) A participant may file a written designation of a beneficiary
who is to receive any shares and cash, if any, from the participant's account
under the Plan in the event of such participant's death subsequent to an
Exercise Date on which the option is exercised but prior to delivery to such
participant of such shares and cash. In addition, a participant may file a
written designation of a beneficiary who is to receive any cash from the
participant's account under the Plan in the event of such participant's death
prior to exercise of the option. If a participant is married and the designated
beneficiary is not the spouse, spousal consent shall be required for such
designation to be effective.

            (b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

        16. Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

        17. Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

        18. Reports. Individual accounts shall be maintained for each
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

                                      -6-

        19. Adjustments Upon Changes in Capitalization, Dissolution,
Liquidation, Merger or Asset Sale.

            (a) Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the Reserves, the maximum number of shares each
participant may purchase per Offering Period (pursuant to Section 7), as well as
the price per share and the number of shares of Common Stock covered by each
option under the Plan which has not yet been exercised shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an option.

            (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The New
Exercise Date shall be before the date of the Company's proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

            (c) Merger or Asset Sale. In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the option, the Offering Period
then in progress shall be shortened by setting a new Exercise Date (the "New
Exercise Date"). The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

                                      -7-
<PAGE>   8

        20. Amendment or Termination.

            (a) The Board of Directors of the Company may at any time and for
any reason terminate or amend the Plan. Except as provided in Section 19 hereof,
no such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Offering Period or the Plan
is in the best interests of the Company and its stockholders. Except as provided
in Section 19 and Section 20 hereof, no amendment may make any change in any
option theretofore granted which adversely affects the rights of any
participant. To the extent necessary to comply with Section 423 of the Code (or
any other applicable law, regulation or stock exchange rule), the Company shall
obtain shareholder approval in such a manner and to such a degree as required.

            (b) Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

            (c) In the event the Board determines that the ongoing operation of
the Plan may result in unfavorable financial accounting consequences, the Board
may, in its discretion and, to the extent necessary or desirable, modify or
amend the Plan to reduce or eliminate such accounting consequence including, but
not limited to:

                (i)altering the Purchase Price for any Offering Period including
an Offering Period underway at the time of the change in Purchase Price;

                (ii) shortening any Offering Period so that Offering Period ends
on a new Exercise Date, including an Offering Period underway at the time of the
Board action; and

                (iii) allocating shares.

        Such modifications or amendments shall not require stockholder approval
or the consent of any Plan participants.

        21. Notices. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

        22. Conditions Upon Issuance of Shares. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without

                                      -8-
<PAGE>   9

limitation, the Securities Act of 1933, as amended, the Securities Exchange Act
of 1934, as amended, the rules and regulations promulgated thereunder, and the
requirements of any stock exchange upon which the shares may then be listed, and
shall be further subject to the approval of counsel for the Company with respect
to such compliance.

        As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

        23. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 20 hereof.

        any disposition of shares and I will make adequate provision for
        Federal, state or other tax withholding obligations, if any, which arise
        upon the disposition of the Common Stock. The Company may, but will not
        be obligated to, withhold from my compensation the amount necessary to

        disposition of Common Stock by me. If I dispose of such shares at any
        time after the expiration of the 2-year holding period, I understand
        that I will be treated for federal income tax purposes as having
        received income only at the time of such disposition, and that such
        income will be taxed as ordinary income only to the extent of an amount
        equal to the lesser of (1) the excess of the fair market value of the
        shares at the time of such disposition over the purchase price which I
        paid for the shares, or (2) 15% of the fair market value of the shares
        on the first day of the Offering Period. The remainder of the gain, if
        any, recognized on such disposition will be taxed as capital gain.

of the royalties listed in Paragraph III.B. herein for the lesser of five (5)
additional years or the life of the last expiring issued patent licensed under
this Agreement's Paragraph II.A; or

                        b.      Licensee may elect to permit the Agreement to
expire in accordance with its terms (including termination of any payments of
royalties to Tessera and termination of any rights of Licensee to use further
any Tessera Patent licensed hereunder).

        B.      Paid-up license. Upon expiration of the five year separate
Patent License Agreement under Paragraph X.A2.a., Licensee shall have a fully
paid-up and perpetual license to the issued, non-expired patents which are the
subject matter of and under the terms of said separate Patent License Agreement.

        C.      Termination for Breach. Either party may terminate this
Agreement due to the other party's breach of this Agreement, such as failure to
perform its duties, obligations, or responsibilities herein (including, without
limitation, failure to pay royalties and provide reports as set forth herein).
The parties agree that such breach will cause substantial damages to the party
not in breach. Therefore, the non-breaching party may terminate this Agreement
if such breach is not cured within sixty (60) days of notice thereof.

        D.      Termination for Assignment. In the event that (i) a party either
sells or assigns substantially all of its assets or business to a third party or

entitled to vote for directors of such party ("Selling Party"), the Selling
Party shall notify the other party of such sale or assignment of assets or the
third party's acquisition. In any case of sale, assignment or acquisition, the
Selling Party shall provide to the other party a written confirmation from such
third party stating that such third party shall expressly undertake all the
terms and conditions of this Agreement to be performed by Selling Party. In the
event that such assignee/transferee does not fulfill obligations under this
Agreement, the other party shall reserve a right to terminate this Agreement.

        E.      Termination for Bankruptcy. In the event that one party becomes
bankrupt, permanently ceases doing business, makes an assignment for the benefit
of its creditors, commits an act of bankruptcy, commences any bankruptcy
proceedings or other proceedings in the nature of bankruptcy proceedings, or has
commenced against it any bankruptcy proceedings or other proceedings in the
nature of bankruptcy proceedings that are not dismissed within sixty (60) days,
then the other party shall have the right to terminate this Agreement
immediately upon its notice. Upon such termination the non-bankrupt party shall
have an option to terminate the obligations of both the parties to transfer or
license Technology, Technical Information, Tessera Patent, or Licensee's
Improvement that is filed after the date of termination for bankruptcy, with the
parties retaining all rights to use any Technical Information and Technology
transferred prior to such termination and/or Tessera Patent and Patent covering
any inventions in Licensee's Improvements, to the extent licensed hereunder,
just prior to such termination for bankruptcy, all such rights remaining in full
force and good standing, subject to continuation of the royalty payments as
stipulated in Paragraph III hereof.

        XIV.    NON-DISCLOSURE:

        A.      The parties agree that all confidential information disclosed
either orally or in writing by one party to the other pursuant to this Agreement
shall, for a period of eight (8) years from the date of first receipt of this
information, not be used except in accordance with the rights and licenses
granted pursuant to this Agreement and shall be maintained in confidence by the
receiving party, provided, however, that such information is designated and
marked as being confidential in nature by the disclosing party at the time of
disclosure to the receiving party and provided further that such information, if
disclosed orally, is reduced to writing, marked as being confidential, and
delivered to the receiving party within thirty (30) days after such disclosure.
Such Confidential Information may be disclosed only to employees of the
receiving party who have a specific need to know such information for the
purpose of the disclosing party. Notwithstanding the foregoing provisions of
this Paragraph:

                1.      The receiving party's obligation with respect to keeping
information confidential shall terminate with respect to any part of such
information which appears in issued patents or printed publications or which
ceases to be confidential or enters the public domain through no fault of the
receiving party;

                2.      The receiving party shall not be precluded from
disclosing or making any use whatsoever of any information which it can show was
in its possession prior to the disclosure made by the furnishing party or which
subsequently lawfully came into the receiving party's possession through
channels independent of the furnishing party or which was developed completely
independent of information provided to receiving party hereunder;

                3.      For the purpose of keeping information confidential the
receiving party shall use efforts commensurate with those which it employs for
the protection of corresponding information of its own, but not less than a
reasonable degree of care to prevent unauthorized use, disclosure,
dissemination, or publication of information transferred hereunder;

                4.      The receiving party shall not be liable for any
disclosure resulting from the sale of any product or component; and

                5.      The receiving party may disclose confidential
information of the party to the receiving party's Suppliers or vendors where
necessary for the manufacture, use or sale of products by the receiving party,
as provided for in Paragraph IX (Supplier).

        B.      The parties hereto shall consult with each other from time to
time and mutually approve promotional materials, including samples, technical
data, or otherwise containing any proprietary and/or confidential information of
the parties, for disclosure to customers by either party or jointly under a
mutually agreeable and reciprocal non-disclosure agreement. Notwithstanding the
parties' obligations hereunder with respect to timely reports and/or disclosures
to the other containing confidential information, breach of this Paragraph XIV
by either party shall be deemed sufficient cause for the other party to
terminate any further obligation to make confidential disclosures to the
breaching party without limiting any other remedy at law. If such a breach
occurs, the non-breaching party shall send a written notification to the
breaching party. The

                                       11
<PAGE>   12

TESSERA CONFIDENTIAL

breaching party will then have fifteen (15) days from the mailing date of the
notification within which to mitigate the effects of the wrongful disclosure
amounting to a breach hereunder. If such actions are sufficient to mitigate the
effects of the wrongful disclosure, the obligation of the Nonbreaching party to
make confidential disclosures shall resume.

        XV.     INDEMNITY:

        A.      Licensee agrees to defend, indemnify and hold Tessera harmless
from and against any and all damages, liabilities, costs and expenses (including
reasonable attorneys' fees and expenses) arising out of or related to
Licensee's use of the Technology. Notwithstanding, Licensee shall not be
required to defend or help defend the validity of any Tessera Patent.

        B.      Tessera agrees to defend, indemnify and hold Licensee harmless
from and against any and all damages, liabilities, costs and expenses (including
reasonable attorney's fees and expenses) arising out of or related to Tessera's
use of Licensee Improvements. Notwithstanding, Tessera shall not be required to
defend or help defend the validity of any Licensee Patent.

nonpayment of royalties, the location of the arbitration shall be San Jose,

RE: Amendment Letter - Change in Definition of "Licensee"

Dear Kevin:

As mentioned in my June 16, 1997 letter to you, Tessera is requesting a
modification to the TCC License Agreement so that Anam (Korea) and Amkor/Anam
(Philippines) are expressly covered under the terms of the Agreement pursuant to
the Affiliate Agreement that both have signed with Tessera. The proposed
modification to the introductory paragraph of the Agreement is as follows:

       "This Agreement is entered into as of this 9th day of May, 1996, between
       TESSERA, INC., a corporation organized under the laws of Delaware
       ("Tessera") and AMKOR ELECTRONICS, INC. a corporation organized under the
       laws of Pennsylvania and its Affiliates ("Licensee") with reference to
       the following facts:"

If you agree with the above revision, please have an authorized representative
of Amkor sign the both copies of this amendment letter

Best regards,
