Both parties hereto acknowledge and agree that they are parties to that certain
Master Non-Disclosure Agreement numbered ****************, the "Master NDA"
pursuant to which they have exchanged confidential and/or proprietary
information under cover of various Confidential Information Transmittal Records
("CITR'S"). Both parties further acknowledge that the Raw Data developed
pursuant to PDF Solutions' services to Conexant under this Agreement shall be
deemed Confidential and shall not be disclosed. Both parties agree that this
Agreement shall not modify, alter or extinguish the Master NDA nor any CITR's
currently existing or to be executed in the future. The parties acknowledge and
agree that during the course of the performance of the mutual obligations
hereunder, each party will occasionally deliver to the other party certain
information (including proprietary information, technical data, trade secrets,
know-how, research, software, developments, inventions, processes, design flows,
methods, methodologies, formulas, algorithms, technologies, designs, drawings,
engineering, hardware configuration information, yield data or other similar
information, and related documentation and information) which the disclosing
party deems to be confidential or proprietary. Such information shall be
considered and treated hereunder as proprietary and other confidential
information if it is marked as "Confidential" or "Proprietary" (hereinafter
referred to as "CONFIDENTIAL INFORMATION"): (i) by stamp or legend if
communicated in writing or other tangible form, or (ii) orally at the time of
disclosure with a written confirmation within thirty days describing the
Confidential Information communicated orally. All restrictions as to use and
disclosure shall apply during such thirty day period. Any recipient of
Confidential Information disclosed pursuant to this Agreement shall hold the
Confidential Information in strictest confidence and shall protect the
Confidential Information by using the same degree of care, but no less than a
reasonable degree of care, to prevent the unauthorized use, disclosure,
dissemination or publication of the Confidential Information as the recipient
uses to protect its own comparable confidential and proprietary information. Any
permitted reproduction of Confidential Information shall contain all
confidential or proprietary legends which appear on the original. If the
disclosing party discloses any software, the recipient is prohibited from
disassembling, decompiling, reverse-engineering or otherwise attempting to
discover or disclose the disclosing party's software or methods or concepts
embodied in such software. Subject to the licenses granted in Section 4, upon
receipt of the written request of the disclosing party, the receiving party will
return, or give written certification of the destruction of all Confidential
Information in any tangible or digital form, including all copies thereof
whether on paper or in digital form, which are in the recipient's possession or
control. The recipient will immediately notify the disclosing party in the event
of any loss or unauthorized disclosure of Confidential Information. The above
restrictions on use and disclosure shall not apply to any Confidential
Information that: (1) is in the public domain or in the possession of the
recipient without restriction at the time of receipt under this Agreement
through no wrongful act or omission of the recipient, (2) is used or disclosed
with the prior written approval of the disclosing party, (3) is used or
disclosed after *** years from the date of expiration or earlier termination of
this Agreement, (4) is independently developed by the recipient without breach
of this Agreement which independent development is supported by reasonable
contemporary evidence, (5) becomes known to the recipient from a source other
than the disclosing party without breach of this

Agreement by the recipient or any other wrongful act or omission by recipient or
any third party; or (6) is required to be disclosed pursuant to law, provided
the recipient uses reasonable efforts to give the disclosing party reasonable
notice of such required disclosure sufficient to give the disclosing party the
opportunity to contest such disclosure. The obligations of confidentiality shall
survive the expiration or sooner termination of this Agreement for a period of
**************** thereafter. Disclosing party assumes no responsibility or
liability whatever under this Agreement for any use of Confidential Information
by the recipient or its customers or agents. Nothing in this Agreement shall
restrict recipient's discretion to transfer or assign its personnel, providing
the obligations of recipient under this Agreement are otherwise met. Each party
understands that the other party may currently or in the future be developing
information internally, or receiving information from third parties that may be
similar to the Confidential Information. Accordingly, nothing in this Agreement
will be construed as a representation or inference that either party will not
develop products, or have products developed for it, or enter into joint
ventures, alliances, or licensing arrangements that, without violation of this
Agreement, compete with the products or systems embodying the Confidential
Information. Further, subject to the provisions of Section 4, either party shall
be free to use for any purpose the "residuals" resulting from access to or work
with such Confidential Information, provided that such party shall maintain the
confidentiality of the Confidential Information as provided herein. The term
"RESIDUALS" means information in non-tangible form, which may be retained by
persons who have had access to the Confidential Information, including ideas,
concepts, know-how or techniques contained therein. Neither party shall have any
obligation to limit or restrict the assignment of such persons or to pay
royalties for any work resulting from the use of residuals. The parties do not
intend that any agency or partnership relationship be created between them by
this Agreement. Each party hereto recognizes and agrees that there is no
adequate remedy at law for a breach of this Section 5, that such a breach would
irreparably harm the disclosing party and that the disclosing party shall be
entitled to seek equitable relief (including, without limitation, injunctions)
with respect to any such breach or potential breach in addition to any other
remedies.

SECTION 6. REPRESENTATIONS AND WARRANTIES

        9.6 Force Majeure. Neither party shall be liable to the other party for
any loss, damage, or penalty arising from delay due to causes beyond its
reasonable control including acts of God, acts of government, war, riots, or
embargoes.

        9.7 Severability. If any term or provision of this Agreement is
determined to be invalid or unenforceable for any reason, it shall be adjusted
rather than voided, if possible, to achieve the intent of the parties to extent
possible. In any event, all other terms and provisions shall be deemed valid and
enforceable to the maximum extent possible.

        9.8 Insurance. PDF Solutions shall carry Workers' Compensation and
Comprehensive General Liability Insurance (including Products, Contractual, and
Automobile Liability) in such form as to protect PDF Solutions and Conexant,
their directors and officers, and the agents and employees as additional
insureds from any claims or omissions of PDF Solutions under this Agreement. PDF
Solutions shall furnish Conexant with a Certificate(s) of Insurance evidencing
limits of liability not less than *********** combined single limit per
occurrence for bodily injury, including death and property damages, prior to
performing any services on site at Conexant's facility. Such insurance shall be
primary and non-contributing to any insurance maintained or obtained by Conexant
and shall not be canceled or materially reduced without thirty (30) days
prior written notice to Conexant. PDF Solutions agrees to waive any rights of
subrogation PDF Solutions or PDF Solutions' insurers may have against Conexant
under applicable Workers' Compensation laws.

        9.9 Export Control Laws and Regulations. Each party, for itself and any
of its employees and agents who may be given access by such party to technical
information pursuant to the performance of the Services hereunder, acknowledges
its obligations to control access to such technical information and to ensure
that such access does not result in a violation of the U.S. Export Control Laws
and Regulations.

        9.10 Disputes. If any claim or controversy arises out of this Agreement,
the parties shall first make a good faith attempt to resolve the matter through
a designated executive officer. The officers having cognizance of the subject
matter of the Agreement for each of the parties shall first meet and make a good
faith attempt to resolve such controversy or claim. In the event such good faith
negotiation fails to settle any dispute within sixty (60) days from
notice of such dispute, the parties shall endeavor to resolve such dispute
arising out of this Agreement by mediation in either Santa Clara County, Orange
County or Los Angeles County California or at such other place as the parties
hereto mutually agree upon, in accordance with the Center for Public Resources
(CPR) Model Procedure for Mediation of a Business Dispute. Unless the parties
agree otherwise, the mediator will be selected from the CPR Panels of
Distinguished Neutrals and each party shall be responsible for its own costs
associated with such mediation. If the matter has not been resolved pursuant to
the aforementioned mediation procedure within sixty (60) days of the
initiation of such procedure, the controversy shall be settled by binding
arbitration by one or three arbitrators, (if three are used, each party shall
select one, and the third shall be selected by mutual agreement of the parties),
conducted in accordance with the Commercial Arbitration Rules of the American
Arbitration Association and judgment upon the award rendered by the
arbitrator(s) may be entered by


                                       13
<PAGE>   14

any court having jurisdiction thereof. The arbitrator(s) shall not be empowered
to award damages in excess of, and/or in addition to, actual damages, including
punitive damages, and the arbitrator(s) shall deliver a reasoned opinion in
connection with his/her/their decision. Nothing herein, however, shall prohibit
either party from seeking injunctive relief if such party would be substantially
prejudiced by a failure to act during the time that such good faith efforts are
being made to resolve the claim or controversy. In the event either party seeks
injunctive relief, the parties agree that jurisdiction will be before a state or
district court seated in either Santa Clara County, Orange County or Los Angeles
County, California. All deadlines in this Section 9.10 may be extended by mutual
agreement.

        9.11 Governing Law. This Agreement and any and all disputes arising
hereunder shall be governed by the internal laws of the State of California.
This Agreement is prepared and executed and shall be interpreted in the English
language only, and no translation of the Agreement into another language shall
have any effect. The parties agree that the United Nations Convention on
Contracts for the International Sale of Goods (1980) is specifically excluded
from and shall not apply to this Agreement.

        9.12 Waiver. The failure of any party hereto to enforce at any time any
of the provisions of this Agreement or to require at any time performance by the
other party of any of the provisions of this Agreement, or any part hereof,
shall not be construed to be a waiver of said provision or to effect the right
of any party to enforce each and every provision in accordance with the terms of
this Agreement.

        9.13 Interpretation. In the event that any term of the Scope of Services
conflicts with the terms of this Agreement, the terms of this Agreement shall
take precedence.

        9.14 Non-Solicitation. Conexant shall not actively solicit or influence
or attempt to influence any person employed by PDF Solutions to terminate or
otherwise cease his or her employment with PDF Solutions or become an employee
of Conexant. PDF Solutions shall not actively solicit or influence or attempt to
influence any person employed by Conexant to terminate or otherwise cease his or
her employment with Conexant or become an employee of PDF Solutions.

        9.15 Drafter. Neither party will be deemed the drafter of this
Agreement, which Agreement will be deemed to have been jointly prepared by the
parties. If this Agreement is ever construed, whether by a court or by an
arbitrator, such court or arbitrator will not construe this Agreement or any
provision hereof against any party as drafter.

        9.16 Entire Agreement. As noted in Section 5 relating to
confidentiality, the parties hereto have a separate confidentiality agreement in
place that will not be affected by this Agreement. The parties also acknowledge
that PDF Solutions is not providing or licensing to Conexant under this
Agreement any existing software programs or products and anticipate that they
will enter into a Software Evaluation and/or Software License Agreement related
to the subject matter hereof. Such agreement shall also not be affected by this
Agreement. Other than these specified agreements, this Agreement shall
constitute the entire agreement between the parties with respect to the subject
matter hereof and: (i) shall supersede all prior contemporaneous oral or written
communications, proposals and


                                       14
<PAGE>   15

representations with respect to its subject matter, and (ii) shall prevail over
any conflicting or additional terms of any statement of work, quote, order
acknowledgment or similar communication between the parties during the term of
this Agreement.

        9.17 Counterparts. This Agreement may be executed in counterparts, each
of which shall be deemed an original, but all of which together will constitute
one and the same instrument.

        9.18 Exhibits. Exhibits "A," "B" and "C" attached hereto are
incorporated herein by this reference as if fully set forth herein.

Conexant's historical ********** rates at *********** (with anticipated yield
improvement of **************** projections after ***********); and the
improvement of Conexant's yield ************** and management of ***********
products targeted **************************** (with anticipated yield
improvement above ******************************** *********** products).

Conexant agrees to pay three types of fees associated with the Services and
Technology: a *********** (the "FIXED FEE"), an *********** with conditions
described below (the "INCENTIVE FEE") and a variable Gainshare fee paid over
************************************** and calculated according to the Gainshare
Fee Calculation models defined below ("GAINSHARE FEE") (collectively referred to
as "FEES"). ***************** ***************************. Conexant shall not
have any liability to PDF Solutions for any Fees incurred in an amount in excess
of ***********.

PRODUCT VOLUME EXCLUDED FROM GAINSHARE FEE COGS REDUCTION CALCULATIONS

The following volume shall be excluded from the calculation of the defect
density for both **************************** and Conexant ********* ********
run at *******:

-   Pre-production lots
-   Engineering lots
-   Lots adversely affected by equipment failures or malfunctions.
-   Lots adversely affected by non-qualified PM adjustments. Non-qualified means
    equipment introduced not verified to process tolerances. Conexant and PDF
    Solutions agree to review the qualification process by ***********. Conexant
    may elect not to make any changes suggested by PDF Solutions that are deemed
    unreasonable or beyond Conexant's control.
-   Mis-processed lots or lots otherwise adversely affected by mishandling.
-   Products identified with yield issues that are not adequately addressed
    during the engineering phase and prematurely introduced into mass
    production for reasons beyond PDF Solutions' control. For products to be
    considered under this exclusion, products must be first identified by PDF
    Solutions during the engineering phase as products to be excluded from the
    calculations. In such an event, products will be excluded from the
    calculations for a grace period of ************** after date product is
    identified by PDF Solutions by written notice.

GAINSHARE FEE CALCULATION SCHEDULE

Gainshare Fee is to be calculated quarterly, but accumulated monthly. The
Gainshare Fee will be calculated during the months of (1)January, (2) April, (3)
July and (4) October for the prior three months. An example schedule is provided
to clarify the calculation dates. Each party will work together in good faith,
to determine and agree upon the appropriate Gainshare amount within the first
twenty (20) days of the stated month.

consolidation or merger of a party in which such party is not the continuing or
surviving corporation, or pursuant to which a material number of shares of such
party's common stock would be converted to cash, securities or other property;
(ii) any sale, exchange or other transfer (in one transaction or series of
related transactions) of all or substantially all the assets of such party;
(iii) any sale or other transfer of stock or assets, any consolidation or
merger, or any other transaction, that results in management or control of the
facility resting with a third party.
