                     (As amended and restated May 15, 1993)

     This Amended and Restated Registration Rights Agreement (this "Agreement")
is entered into as of the 15th day of May, 1993, and amends and restates in full
the Registration Rights Agreement originally entered into as of the 13th day of
June, 1991 by and among Tessera, Inc. (formerly IST Associates Inc.), a Delaware
corporation (the "Company") and the undersigned or identified holders of
securities of the Company.

                                  WITNESSETH:

     WHEREAS, the investors set forth on Schedule A hereto (the "Prior
Investors") are the owners of shares of common stock, par value $.01 per share
of the Company (the "Common Stock");

     WHEREAS, the investors set forth on Schedule B hereto (the "Prior
Warrantholders") are the holders of warrants, dated June 15, 1990 (the "1990
Warrants"), to purchase shares of Common Stock (the "1990 Warrant Shares");

     WHEREAS, the investors set forth in Schedule C hereto (the "Preferred
Investors") have acquired shares of the Company's Series A 10% Cumulative
Convertible Preferred Stock, par value $.01 per share and Series B 10%
Cumulative Convertible Preferred Stock, par value $.01 per share (the "Series B
Preferred Stock" and, together with the Series A Preferred Stock, the "Preferred
Stock"), and each such share of Preferred Stock is initially convertible into
one share of Common Stock (the "Conversion Share"), pursuant to that certain
Stock Purchase Agreement as of June 13, 1991 (the "Stock Purchase Agreement") by
and among the Company and the Preferred Investors;

     WHEREAS, certain investors set forth on Schedule D hereto (the "New
Warrantholders") have or are concurrently contemplating acquiring from the

<PAGE>   2
     NOW, THEREFORE, in consideration of the mutual promises and covenants
herein contained and for the other good and valuable consideration, the
Investors and the Company agree as follows:

     1. Demand Registration Rights.

     (a) From time to time, upon the demand in writing of one or more Venture
Investors or any transferees or assignees of such Venture Investors (the
"Transferees") to have any or all of the Conversion Shares (including, for
purposes hereof, shares of Common Stock issued upon conversion of the Preferred
Warrant Shares, if and when they are issued) and/or the 1990 Warrant Shares or
the New Warrant Shares (if and when they are issued) (collectively, the "Warrant
Shares" and, together with the Conversion Shares, the "Venture Shares") which
they own or have the right to acquire offered to the public pursuant to a bona
fide underwritten public offering, the Company shall give written notice of such
demand promptly to all of the Investors and Transferees providing such Investors
or Transferees with the opportunity to participate in such demand registration.
Such Investors and Transferees shall notify the Company, within fifteen (15)
days of receipt of such notice from the Company, whether they desire to have any
or all of the Conversion Shares, Warrant Shares or shares of Common Stock
(collectively, "Shares") which they own or have the right to acquire, included
in such public offering. The right of the Prior Investors to participate in such
registration is subject to Section 1(d). The Company will thereafter diligently
prepare, file and process to effectiveness a registration statement under the
Securities Act of 1933 (the "1933 Act") (on and in compliance with such
applicable registration forms as may be designated by the Venture Investors or
Transferees holding a majority of the Venture Shares to be included therein) and
any amendments or supplements required to be filed to ensure that such
registration remains effective under the 1933 Act, to permit the Investors and
Transferees or any of them, to offer and sell to the public the number of Shares
demanded to be registered. The Company shall file the aforesaid registration
statement as soon as reasonably practicable, and in any event, within forty-five
(45) days following receipt of such written request if the Company has
previously consummated a public offering of the Common Stock, otherwise within
ninety (90) days following receipt of such written request. The Company shall
use its best efforts to cause the registration statement to become and remain
effective until the earlier of the sale of all the Shares included in the
registration statement or the expiration of one hundred eighty (180) days from
the effective date thereof.

                                     - 2 -
<PAGE>   3
     (b)  Notwithstanding the foregoing:

          (i)  The Company shall not be required to comply with the demand for
registration pursuant to Section 1(a), unless such demand is for the
registration of at least one-third of the total number of Conversion Shares
issued under the Stock Purchase Agreement or pursuant to exercise of the
Preferred Warrants (if and when issued) and Warrant Shares issued pursuant to
exercise of the 1990 Warrants and the New Warrants (if and when issued).

          (ii) The Company shall not be required to cause a registration
statement pursuant to Section 1(a) to become effective prior to sixty (60) days
following the effective date of a registration statement initiated by the
Company.

     (c)  Subject to any generally applicable blue sky requirements with respect
to the allocation of expenses, in the case of (i) the first two demand
registrations under this Section 1, (ii) any demand registration in which the
Company includes securities to be registered and (iii) any demand registration
that can be effected on Form S-3 or any successor form (up to a maximum of two
Form S-3 registrations per year), the Company shall bear all costs and expenses
of the registration statement (and all amendments and supplements thereto)
required to effect such registration, including legal, printing, and accounting
expenses, and Securities and Exchange Commission ("SEC") filing fees and blue
sky fees and expenses, but the Company shall have no obligation to pay or
otherwise bear any portion of (i) transfer taxes payable on account of the
transfers of the Shares, or (ii) any underwriter's commission, discounts and
expenses attributable to the Shares being offered and sold by the Investors or
the Transferees. A demand registration which does not become effective or does
not result in the registration and sale of at least ninety percent (90%) of the
Venture Shares demanded to be registered by the Venture Investors and
Transferees, shall not be deemed a demand registration for purposes hereof.

     (d)  If, at the time of the first demand registration, the Company has not
consummated an underwritten public offering, such demand registration shall be
made through an underwriter. If a demand registration under this Section 1 is to
be made through an underwriter, the Venture Investors and Transferees selling a
majority of the Venture Shares being sold thereunder shall have the right to
designate the lead underwriter. In the event the managing underwriter for such
offering and sale advises that the number of shares proposed to be sold in any
such offering pursuant to this Section 1 is greater than the number of shares
which the underwriter believes feasible to sell at that time, at the price and
upon the terms

                                     - 3 -
<PAGE>   4
approved by or on behalf of Venture Investors and Transferees holding a majority
of the Venture shares to be included in such registration statement, then the
number of shares which the underwriter believes may be sold shall be allocated
in the following order; (i) in full to the Venture Investors and the
Transferees, pro rata according to the number of Venture Shares owned by them,
then (ii) if there is any balance of available shares, in full to the Prior
Investors (pro rata according to the number of Shares owned by them), and (iii)
if there is any balance of available shares, in full to the Company, in the
event that the offering is not underwritten, the Prior Investors and the Company
shall be precluded from selling any shares pursuant to a registration statement
under Section 1 hereof until all of the Venture Shares included in such
registration statement by the Venture Investors and Transferees have been sold.

     2. Piggy-Back Registration Rights. On each occasion, if any, following the
date hereof that the Company contemplates filing with the SEC a registration
statement under the 1933 Act relating in whole or in part to the primary offer
and sale of shares of Common Stock, other than a registration statement which
exclusively relates to the registration statement under an employee stock
option, bonus or other compensation plan (and other than a demand registration
pursuant to section 1), the Company shall so notify the Investors and the
Transferees in writing of its intention to do so at least thirty (30) days prior
to the filing of each such registration statement. Each Investor and Transferee
who gives written notice to the company, within fifteen (15) days of receipt of
such notice from the Company, of such Investor's or Transferee's desire to have
any of its Shares included in such registration statement, may, subject to the
provisions of this Section 2, have its Shares so included. The Company shall
file any required amendments of or supplements to any registration statement
filed pursuant to this Section 2 and otherwise use its best efforts to insure
that such registration statement remains in effect under the 1933 Act until the
earlier of the sale of all of this Shares included in the registration or the
expiration of one hundred eighty (180) days from the effective date thereof,
subject to Section 3. The Company shall, subject to any generally applicable
blue sky requirements with respect to allocation of expenses, bear all costs and
expenses in connection with the registration statement and sale of any such
Shares other than the expenses which would be borne by the selling shareholders
in a demand registration pursuant to Section 1(c) hereof. Notwithstanding the
foregoing, if the managing underwriter of any such offering determines that the
number of shares proposed to be sold by the company and/or by the Investors and
the Transferees is greater than the number of shares which the underwriter
believes feasible to sell at that time, at the price and upon the terms approved
by the company, then the number of shares which the underwriter believes may be
sold shall be

                                      -4-
<PAGE>   5
allocated in the following order: (i) primary shares being offered by the
Company and (ii) pro rata among the Investors and the Transferees, according to
the number of Shares owned by them.

     3.   Additional Covenants Concerning Sale of Shares. If permitted by
applicable law and regulations, the Company at the request of any Investor or
Transferee whose Shares are included in any registration statement filed by the
Company, shall file such amendments and/or supplements to such registration
statement, and take such other steps, as may be required to maintain such
registration statement in effect, and to keep the information therein current,
so long as any of the Shares included therein remain unsold. In connection with
any registration statement referred to in this Agreement, the Company shall
furnish to each Investor or Transferee whose Shares are included therein (or to
any broker or other person at its request) a reasonable number of copies of
such registration statement, each amendment and supplement thereto and each
document included therein, and such number of copies of the then current
prospectus included therein as they may from time to time reasonably request.

     4.   Blue Sky Provisions. The Company, at its expense, shall cause any of
the Shares included in a registration statement referred to in this Agreement
to be qualified under the laws of such number of jurisdictions as the Investors
and Transferees, or the managing underwriter named therein, may reasonably
designate, and the Company will continue such qualifications in effect so long
as maybe necessary to comply with all applicable laws regulating sales of
securities.

     5.   Advertising the Investors and the Transferees. In connection with any
registration statement referred to in this Agreement, the Company will promptly
advise each Investor and each Transferee whose Shares are included therein, and
confirm such advice in writing (i) when the registration statement has become
effective, (ii) upon the filing of any amendment or supplement to the
registration statement becomes effective, and (iv) of any request by the SEC
for any amendment or supplement to the registration statement or prospectus or
for additional information. If at any time the SEC should institute or threaten
to institute any proceeding for the purpose of issuing, or should issue, a stop
order suspending the effectiveness of the registration statement, the Company
will promptly notify the Investors and Transferees whose Shares are included in
such registration statement, and will use its best efforts to prevent the
issuance of any such stop order or to obtain the withdrawal thereof as soon as
possible; and the Company will advise the Investors and the Transferees
promptly of any order to communication of any public board or body addressed

                                     - 5 -
<PAGE>   6
to the Company suspending or threatening to suspend the qualification of any
shares of Common Stock for sale in any jurisdiction.

      6.    Indemnification.

            (a)   With respect to the registration rights described in Section 1
and 2 hereof, the Company hereby agrees to indemnify, hold harmless and defend
each Investor and each Transferee and each person, if any, who is deemed a
controlling person of any such Investor or Transferee within the meaning of the
1933 Act, against any and all losses, claims, damages, liabilities and expenses
(including legal and other expenses incurred in investigating and defending
against the same), to which they, or any of them, may become subject under the
1933 Act or other statute or common law, arising out of or based upon (i) any
alleged untrue statement of a material fact contained in any registration
statement, preliminary prospectus or prospectus included therein, or any
amendment thereof or supplement thereto, or (ii) the alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements contained therein not misleading; provided, however, that the
indemnity contained in this Section 6(a) shall not apply to any such alleged
untrue statement or omission made in reliance upon and in conformity with the
information furnished in writing to the Company by or on behalf of such Investor
or Transferee. As soon as practicable after the receipt by any Investor or
Transferee of notice of claim or action against any of the Investors and
Transferees in respect of which indemnity may be sought from the Company
hereunder, such Investor or Transferee shall notify the Company thereof in
writing, and the Company shall assume the defense of such claim or action (and
the cost thereof) by counsel of its own choosing, who shall be reasonably
satisfactory to a majority in interest of the Investors and Transferees.

            (b)   Each Investor, severally but not jointly, hereby agrees, and
each Transferee, by exercising its registration rights under this Agreement
shall be deemed to agree, to indemnify, hold harmless and defend the Company,
its directors and officers, and each person, if any, who is deemed a
controlling person of the Company within the meaning of the 1933 Act, and each
other Investor and Transferee against any and all loses, claims, damages,
liabilities and expenses (including reasonable legal or other expenses incurred
investigating and defending against the same), to which they or any of them may
become subject under the 1933 Act or other statute or common law, arising out
of or based upon (i) alleged untrue statement of a material fact contained in
any such registration statement or preliminary prospectus or prospectus
included therein, or any amendment thereof or supplement thereto, or (ii) the
alleged

                                      - 6 -
<PAGE>   7

omission to state therein a material fact required to be stated therein or
necessary to make the statements contained therein not misleading; provided,
however, that the indemnity contained in this Section 6(b) shall apply in each
case only to the extent such statement or omission was made in reliance upon
and in conformity with written information furnished to the Company by or on
behalf of such Investor or Transferee in connection with the preparation of the
registration statement. The Company, and any other person in respect of which
indemnity may be sought from an Investor or Transferee hereunder, shall, as
soon as practicable after the receipt of notice of any claim or action against
the Company or such other person or entity, notify such Investor or Transferee
thereof in writing, and such Investor and Transferee shall assume the defense
of any such claim or action (and the cost thereof) by counsel of its own
choosing, who shall be reasonably satisfactory to a majority in interest of the
Investors and Transferees.

     7. Registration under Securities Exchange Act of 1934. If the Company
shall at any time have completed a public offering of shares of Common Stock,
it shall thereafter take such steps as may be necessary to register the Common
Stock under Section 12 of the Securities Exchange Act of 1934, to maintain such
status, and to file with the SEC all current reports and other information as
may be necessary to enable the Investors or the Transferees to effect sales of
Shares in reliance upon Rule 144 under the 1933 Act.

     8. Entire Agreement. This Agreement, together with all Schedules hereto,
constitutes the entire agreement among the parties pertaining to the subject
matter hereof and supersedes all prior agreement, understandings, registrations
and discussions, whether written or oral, of the parties.

     9. Successors and Assigns. All terms, covenants, obligations and
undertakings in this Agreement shall be binding upon and inure to the benefit
of the Company, the Investors, and each of their respective successors,
assigns, transferees, heirs, distributees and personal representatives;
provided, however that Company may not assign its obligations hereunder.

     10. Amendments, Modifications, Waivers and Discharges. Neither this
Agreement nor any provisions hereunder may be amended, modified, waived or
discharged unless such amendment, modification, waiver of discharge is agreed
to in writing, duly subscribed and acknowledged with the same formality as this
Agreement, and signed by Investors holding at least fifty-one percent (51%) in
aggregate interest of the Shares then issued and outstanding, subject to
Section 17 hereof. Any waiver of a right, term or provision hereunder by the
Investors shall not be deemed a continuing waiver and shall not prevent the
Investors

                                     - 7 -

or any of them) from thereafter enforcing such right, term, or provision, and
the failure of the Investors (or any of them) to insist in one or more
instances upon strict performance by the Company of any of the terms and
provisions of this agreement shall not be construed as a waiver or
relinquishment for the future of any such right, term or provision, but the
same shall continue in full force and effect.

delivered in the State of New York, and the validity and interpretation hereof

unenforceable under applicable law shall be, if possible, modified or altered
to conform to such applicable law, or if not possible, shall be deemed to be

                           INDEMNIFICATION AGREEMENT

        THIS INDEMNIFICATION AGREEMENT ("Agreement") is made as of this ___ day
of _______________, 2000 by and between TESSERA, INC., a Delaware corporation
(the "Company"), and __________________________ ("Indemnitee").

        WHEREAS, the Company and Indemnitee recognize the increasing difficulty
in obtaining directors' and officers' liability insurance, the significant
increases in the cost of such insurance and the general reductions in the
coverage of such insurance;

        WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting officers and directors
to expensive litigation risks at the same time as the availability and coverage
of liability insurance has been severely limited;

        WHEREAS, Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other officers and
directors of the Company may not be willing to continue to serve as officers and
directors without additional protection; and

        WHEREAS, the Company desires to attract and retain the services of
highly qualified individuals, such as Indemnitee, to serve as officers and
directors of the Company and to indemnify its officers and directors so as to
provide them with the maximum protection permitted by law.

        NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

        1.      INDEMNIFICATION.

               (a) Third Party Proceedings. The Company shall indemnify
Indemnitee if Indemnitee is or was a party or is threatened to be made a party
to any threatened, pending or completed action or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the Company) by reason of the fact that Indemnitee is or was a
director, officer, employee or agent of the Company, or any subsidiary of the
Company, by reason of any action or inaction on the part of Indemnitee while an
officer or director or by reason of the fact that Indemnitee is or was serving
at the request of the Company as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) actually and reasonably incurred by
Indemnitee in connection with such action or proceeding if Indemnitee acted in
good faith and in a manner Indemnitee believed to be in the best interests of
the Company, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe Indemnitee's conduct was unlawful. The termination
of any action or proceeding by judgment, order, settlement, conviction, or upon
a plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that (i) Indemnitee did not act in good faith and in a manner which
Indemnitee reasonably believed to be in the best interests of the Company, or
(ii) with respect to any criminal action or proceeding, Indemnitee had
reasonable cause to believe that Indemnitee's conduct was unlawful.

<PAGE>   2

               (b) Proceedings By or in the Right of the Company. The Company
shall indemnify Indemnitee if Indemnitee was or is a party or is threatened to
be made a party to any threatened, pending or completed action or proceeding by
or in the right of the Company or any subsidiary of the Company to procure a
judgment in its favor by reason of the fact that Indemnitee is or was a
director, officer, employee or agent of the Company, or any subsidiary of the
Company, by reason of any action or inaction on the part of Indemnitee while an
officer or director or by reason of the fact that Indemnitee is or was serving
at the request of the Company as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees) and, to the fullest extent
permitted by law, amounts paid in settlement, in each case to the extent
actually and reasonably incurred by Indemnitee in connection with the defense or
settlement of such action or proceeding if Indemnitee acted in good faith and in
a manner Indemnitee believed to be in the best interests of the Company and its
shareholders.

        2.      EXPENSES; INDEMNIFICATION PROCEDURE.

               (a) Advancement of Expenses. The Company shall advance all
expenses incurred by Indemnitee in connection with the investigation, defense,
settlement or appeal of any civil or criminal action or proceeding referenced in
Section 1(a) or (b) hereof (but not amounts actually paid in settlement of any
such action or proceeding). Indemnitee hereby undertakes to repay such amounts
advanced only if, and to the extent that, it shall ultimately be determined that
Indemnitee is not entitled to be indemnified by the Company as authorized
hereby. The advances to be made hereunder shall be paid by the Company to
Indemnitee within twenty (20) days following delivery of a written request
therefor by Indemnitee to the Company.

               (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a
condition precedent to his right to be indemnified under this Agreement, give
the Company notice in writing as soon as practicable of any claim made against
Indemnitee for which indemnification will or could be sought under this
Agreement. Notice to the Company shall be directed to the Chief Executive
Officer of the Company at the address shown on the signature page of this
Agreement (or such other address as the Company shall designate in writing to
Indemnitee). Notice shall be deemed received three business days after the date
postmarked if sent by domestic certified or registered mail, properly addressed;
otherwise notice shall be deemed received when such notice shall actually be
received by the Company. In addition, Indemnitee shall give the Company such
information and cooperation as it may reasonably require and as shall be within
Indemnitee's power.

               (c) Procedure. Any indemnification provided for in Section 1
shall be made no later than forty-five (45) days after receipt of the written
request of Indemnitee. If a claim under this Agreement, under any statute, or
under any provision of the Company's Articles of Incorporation or By-laws
providing for indemnification, is not paid in full by the Company within
forty-five (45) days after a written request for payment thereof has first been
received by the Company, Indemnitee may, but need not, at any time thereafter
bring an action against the Company to recover the unpaid amount of the claim
and, subject to Section 13 of this Agreement, Indemnitee shall also be entitled
to be paid for the expenses (including attorneys' fees) of bringing such action.
It shall be a defense to any such action (other than an action brought to
enforce a claim for expenses incurred in connection with any action or
proceeding in advance of its final disposition) that Indemnitee has not met the
standards of conduct which make it permissible under applicable law for the
Company to

                                      -2-
<PAGE>   3

indemnify Indemnitee for the amount claimed, and Indemnitee shall be entitled to
receive interim payments of expenses pursuant to Subsection 2(a) unless and
until such defense may be finally adjudicated by court order or judgment from
which no further right of appeal exists. It is the parties' intention that if
the Company contests Indemnitee's right to indemnification, the question of
Indemnitee's right to indemnification shall be for the court to decide, and
neither the failure of the Company (including its Board of Directors, any
committee or subgroup of the Board of Directors, independent legal counsel, or
its shareholders) to have made a determination that indemnification of
Indemnitee is proper in the circumstances because Indemnitee has met the
applicable standard of conduct required by applicable law, nor an actual
determination by the Company (including its Board of Directors, any committee or
subgroup of the Board of Directors, independent legal counsel, or its
shareholders) that Indemnitee has not met such applicable standard of conduct,
shall create a presumption that Indemnitee has or has not met the applicable
standard of conduct.

               (d) Notice to Insurers. If, at the time of the receipt of a
notice of a claim pursuant to Section 2(b) hereof, the Company has director and
officer liability insurance in effect, the Company shall give prompt notice of
the commencement of such proceeding to the insurers in accordance with the
procedures set forth in the respective policies. The Company shall thereafter
take all necessary or desirable action to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such proceeding in
accordance with the terms of such policies.

               (e) Selection of Counsel. In the event the Company shall be
obligated under Section 2(a) hereof to pay the expenses of any proceeding
against Indemnitee, the Company, if appropriate, shall be entitled to assume the
defense of such proceeding, with counsel approved by Indemnitee, which approval
shall not be unreasonably withheld, upon the delivery to Indemnitee of written
notice of its election so to do. After delivery of such notice, approval of such
counsel by Indemnitee and the retention of such counsel by the Company, the
Company will not be liable to Indemnitee under this Agreement for any fees of
counsel subsequently incurred by Indemnitee with respect to the same proceeding,
provided that (i) Indemnitee shall have the right to employ his counsel in any
such proceeding at Indemnitee's expense; and (ii) if (A) the employment of
counsel by Indemnitee has been previously authorized by the Company, (B)
Indemnitee shall have reasonably concluded that there may be a conflict of
interest between the Company and Indemnitee in the conduct of any such defense
or (C) the Company shall not, in fact, have employed counsel to assume the
defense of such proceeding, then the fees and expenses of Indemnitee's counsel
shall be at the expense of the Company.

        3.      ADDITIONAL INDEMNIFICATION RIGHTS; NONEXCLUSIVITY.

               (a) Scope. Notwithstanding any other provision of this Agreement,
the Company hereby agrees to indemnify the Indemnitee to the fullest extent
permitted by law, notwithstanding that such indemnification is not specifically
authorized by the other provisions of this Agreement, the Company's Articles of
Incorporation, the Company's By-laws or by statute. In the event of any change,
after the date of this Agreement, in any applicable law, statute or rule which
expands the right of a California corporation to indemnify a member of its board
of directors, an officer or other corporate agent, such changes shall be, ipso
facto, within the purview of Indemnitee's rights and Company's obligations,
under this Agreement. In the event of any change in any applicable law, statute
or rule which narrows the right of a California corporation to indemnify a
member of its

                                      -3-
<PAGE>   4

Board of Directors, an officer or other corporate agent, such changes, to the
extent required by such law, statute or rule to be applied to this Agreement,
shall have the effect on this Agreement and the parties' rights and obligations
hereunder as is required by such law, statute or rule.

               (b) Nonexclusivity. The indemnification provided by this
Agreement shall not be deemed exclusive of any rights to which Indemnitee may be
entitled under the Company's Articles of Incorporation, its By-laws, any
agreement, any vote of shareholders or disinterested directors, the California
General Corporation Law, or otherwise, both as to action in Indemnitee's
official capacity and as to action in another capacity while holding such
office. The indemnification provided under this Agreement shall continue as to
Indemnitee for any action taken or not taken while serving in an indemnified
capacity even though he may have ceased to serve in such capacity at the time of
any action or other covered proceeding.

        4. PARTIAL INDEMNIFICATION. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of the expenses, judgments, fines or penalties actually or reasonably
incurred by him in the investigation, defense, appeal or settlement of any civil
or criminal action or proceeding, but not, however, for the total amount
thereof, the Company shall nevertheless indemnify Indemnitee for the portion of
such expenses, judgments, fines or penalties to which Indemnitee is entitled.

        5. MUTUAL ACKNOWLEDGMENT. Both the Company and Indemnitee acknowledge
that in certain instances, Federal law or applicable public policy may prohibit
the Company from indemnifying its directors and officers under this Agreement or
otherwise. Indemnitee understands and acknowledges that the Company has
undertaken or may be required in the future to undertake with the Securities and
Exchange Commission to submit the question of indemnification to a court in
certain circumstances for a determination of the Company's right under public
policy to indemnify Indemnitee.

        6. DIRECTORS' AND OFFICERS' LIABILITY INSURANCE. The Company shall, from
time to time, make the good faith determination whether or not it is practicable
for the Company to obtain and maintain a policy or policies of insurance with
reputable insurance companies providing the officers and directors of the
Company with coverage for losses from wrongful acts, or to ensure the Company's
performance of its indemnification obligations under this Agreement. Among other
considerations, the Company will weigh the costs of obtaining such insurance
coverage against the protection afforded by such coverage. In all policies of
directors' and officers' liability insurance, Indemnitee shall be named as an
insured in such a manner as to provide Indemnitee the same rights and benefits
as are accorded to the most favorably insured of the Company's directors, if
Indemnitee is a director; or of the Company's officers, if Indemnitee is not a
director of the Company but is an officer; or of the Company's key employees, if
Indemnitee is not an officer or director but is a key employee. Notwithstanding
the foregoing, the Company shall have no obligation to obtain or maintain such
insurance if the Company determines in good faith that such insurance is not
reasonably available, if the premium costs for such insurance are
disproportionate to the amount of coverage provided, if the coverage provided by
such insurance is limited by exclusions so as to provide an insufficient
benefit, or if Indemnitee is covered by similar insurance maintained by a
subsidiary or parent of the Company.

                                      -4-
<PAGE>   5

        7. SEVERABILITY. Nothing in this Agreement is intended to require or
shall be construed as requiring the Company to do or fail to do any act in
violation of applicable law. The Company's inability, pursuant to court order,
to perform its obligations under this Agreement shall not constitute a breach of
this Agreement. The provisions of this Agreement shall be severable as provided
in this Section 7. If this Agreement or any portion hereof shall be invalidated
on any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify Indemnitee to the full extent permitted by any applicable
portion of this Agreement that shall not have been invalidated, and the balance
of this Agreement not so invalidated shall be enforceable in accordance with its
terms.

        8. EXCEPTIONS. Any other provision herein to the contrary
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

               (a) Excluded Acts. To indemnify Indemnitee for any acts or
omissions or transactions from which a director may not be relieved of liability
under the California General Corporation Law.

               (b) Claims Initiated by Indemnitee. To indemnify or advance
expenses to Indemnitee with respect to proceedings or claims initiated or
brought voluntarily by Indemnitee and not by way of defense, except with respect
to proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other statute or law or otherwise as required under
Section 317 of the California General Corporation Law, but such indemnification
or advancement of expenses may be provided by the Company in specific cases if
the Board of Directors has approved the initiation or bringing of such suit; or

               (c) Lack of Good Faith. To indemnify Indemnitee for any expenses
incurred by the Indemnitee with respect to any proceeding instituted by
Indemnitee to enforce or interpret this Agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
Indemnitee in such proceeding was not made in good faith or was frivolous; or

               (d) Insured Claims. To indemnify Indemnitee for expenses or
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA excise taxes or penalties, and amounts paid in settlement) which
have been paid directly to Indemnitee by an insurance carrier under a policy of
directors' and officers' liability insurance maintained by the Company; or

               (e) Claims Under Section 16(b). To indemnify Indemnitee for
expenses and the payment of profits arising from the purchase and sale by
Indemnitee of securities in violation of Section 16(b) of the Securities
Exchange Act of 1934, as amended, or any similar successor statute.

        9. EFFECTIVENESS OF AGREEMENT. To the extent that the indemnification
permitted under the terms of certain provisions of this Agreement exceeds the
scope of the indemnification expressly permitted by Section 317 of the
California General Corporation Law, such provisions shall not be effective
unless and until the Company's Articles of Incorporation authorize such
additional rights of indemnification. In all other respects, the balance of this
Agreement shall be effective as of the date set forth on the first page and may
apply to acts or omissions of Indemnitee which occurred prior to such date if
Indemnitee was an officer, director, employee or other agent of the Company, or
was

                                      -5-
<PAGE>   6

serving at the request of the Company as a director, officer, employee or agent
of another corporation, partnership, joint venture, trust or other enterprise,
at the time such act or omission occurred.

        10.     CONSTRUCTION OF CERTAIN PHRASES.

               (a) For purposes of this Agreement, references to the "Company"
shall also include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, employees or
agents, so that if Indemnitee is or was a director, officer, employee or agent
of such constituent corporation, or is or was serving at the request of such
constituent corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, Indemnitee
shall stand in the same position under the provisions of this Agreement with
respect to the resulting or surviving corporation as Indemnitee would have with
respect to such constituent corporation if its separate existence had continued.

               (b) For purposes of this Agreement, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on Indemnitee with respect to an employee
benefit plan; and references to "serving at the request of the Company" shall
include any service as a director, officer, employee or agent of the Company
which imposes duties on, or involves services by, such director, officer,
employee or agent with respect to an employee benefit plan, its participants, or
beneficiaries.

        11. COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall constitute an original.

        12. SUCCESSORS AND ASSIGNS. This Agreement shall be binding upon the
Company and its successors and assigns, and shall inure to the benefit of
Indemnitee and Indemnitee's estate, heirs, legal representatives and assigns.

        13. ATTORNEYS' FEES. In the event that any action is instituted by
Indemnitee under this Agreement to enforce or interpret any of the terms hereof,
Indemnitee shall be entitled to be paid all costs and expenses, including
reasonable attorneys' fees, incurred by Indemnitee with respect to such action,
unless as a part of such action, a court of competent jurisdiction determines
that each of the material assertions made by Indemnitee as a basis for such
action were not made in good faith or were frivolous. In the event of an action
instituted by or in the name of the Company under this Agreement or to enforce
or interpret any of the terms of this Agreement, Indemnitee shall be entitled to
be paid all costs and expenses, including reasonable attorneys' fees, incurred
by Indemnitee in defense of such action (including with respect to Indemnitee's
counterclaims and cross-claims made in such action), unless as a part of such
action the court determines that each of Indemnitee's material defenses to such
action were made in bad faith or were frivolous.

        14. NOTICE. All notices, requests, demands and other communications
under this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and receipted for by the party addressee, on the date of such
receipt, or (ii) if mailed by domestic certified or

                                      -6-
<PAGE>   7

registered mail with postage prepaid, on the third business day after the date
postmarked. Addresses for notice to either party are as shown on the signature
page of this Agreement, or as subsequently modified by written notice.

        15. CONSENT TO JURISDICTION. The Company and Indemnitee each hereby
irrevocably consent to the jurisdiction of the courts of the State of California
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be brought only in the state courts of the State of California.

        16. CHOICE OF LAW. This Agreement shall be governed by and its
provisions construed in accordance with the laws of the State of California as
applied to contracts between California residents entered into and to be
performed entirely within California.
