                                  ARTICLE III

                    REPRESENTATIONS AND WARRANTIES OF SELLER

     Seller hereby represents and warrants to Buyer that the statements

Agreement throughout this Article 3).

     3.1 Organization. As of the date of this Agreement, Seller is a corporation
duly organized, validly existing and in good standing under the laws of the
State of Delaware. Seller intends to file a Certificate of Dissolution with the

     3.2 Authority. Seller has all requisite corporate power and authority to
enter into this Agreement, and, subject to obtaining the Stockholder Approval
(as defined in Section 8.2(d)), to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement, and the consummation of

corporate action on the part of Seller, and no further action is required on the
part of Seller to authorize this Agreement and the transactions contemplated
hereby, subject only to obtaining the Stockholder Approval (as defined in

     3.3 Title to and Condition of Acquired Assets.

           (a) Title to Acquired Assets. To Seller's knowledge, Seller has good
and marketable legal title to all the Acquired Assets purchased by Buyer herein,
which shall to Seller's knowledge at Closing be free and clear of all liens,
encumbrances and other liabilities or charges except for Permitted Liens unless
otherwise agreed to in writing by the Parties. The execution and delivery of
this Agreement, and the consummation of the transactions contemplated hereby,
will not result in a breach of any material term of material agreement or other
material instrument to which Seller is party or by which it is bound and to
Seller's knowledge will not result in the creation of a lien, charge or
encumbrance on, or give to others any interests or right in, any of the Acquired
Assets.

                                                                             -4-

<PAGE>

            (b) Condition of Assets. All tangible Acquired Assets purchased by
Buyer hereunder are in use and in good condition and have been constantly
maintained in good repair; and all said assets are in compliance with all
applicable laws and regulations.

            (a) To the knowledge of Seller, Seller is the sole and exclusive
owner of, and has good, clear and marketable title to, said Trademarks, Patents
or other Intellectual Property Rights listed in Schedule A as being owned by it,
and to Seller's knowledge, there are no claims, liens, restrictions or other
encumbrances on any of the Trademarks, Patents or other Intellectual Property
Rights which Seller owns or uses. Other than as disclosed on Schedule 3.4(a), to
Seller's knowledge, Seller is not in infringement of, nor has infringed, any
right whatsoever of any third party with respect to any Trademark, Patent or
other Intellectual Property Right in a manner which would have a material effect
on the value of the Acquired Assets as a whole.

            (b) To Seller's knowledge, Schedule A appended hereto accurately
sets forth and describes all the material governmental registrations, licenses
or permits obtained with respect to the Acquired Assets, including all
applications or registrations therefore. To whatever extent said registrations,
licenses or permits are assignable under law, Seller shall use its commercially
reasonable efforts, upon request from Buyer, to arrange for their transfer and
assignment to Buyer as soon as possible after Closing.

     3.5 Absence of Changes. Since May 31, 2002, there has not been any material
damage or destruction in the nature of a casualty or loss of any nature
whatsoever, whether covered by insurance or not, adversely affecting any
Acquired Assets purchased by Buyer hereunder.

     3.6 Use of the Seller Trade Marks and Name. At Closing Seller shall
transfer and convey to Buyer Seller's rights and registrations of all
trademarks, logos, service marks, copyrights, trade dress/packing designs (past,
present and those being conceived), and trade names listed on Schedule A in all
jurisdictions. To Seller's knowledge, there are no claims, liens, encumbrances
or other obligations or liabilities on such marks and names or the right to use
same, and the use of said Seller names does not and will not violate any right
or interest of any third party. Seller hereby renounces, surrenders and waives
all rights, title or interest to and in the use of said Seller names and/or any
names similar to the Seller names after Closing in U.S.A., R.O.C. and/or other
countries, forever and absolutely; provided however that nothing herein shall
require that Seller change its corporate name following the Closing and Seller
shall be entitled to continue to be known by, and use to the extent reasonably
necessary, its existing corporate name.

     3.7 Taxes. All national and local taxes including property and other taxes
affecting the Acquired Assets relevant thereto which are due and payable by
Seller through the Closing Date have been paid, or will at the Closing Date have
been paid in full by Seller, or if mutually agreed to in writing by Buyer and
Seller, may be paid directly by Buyer, with appropriate reductions from the
Purchase Price.

                                                                             -5-

     Either Party may send any notice, request, demand, claim, or other
communication hereunder to the intended recipient at the address set forth above
using any other means (including personal delivery, expedited courier, messenger
service, facsimile, telex, ordinary mail, or electronic mail), but no such
notice, request, demand, claim, or other communication shall be deemed to have
been duly given unless and until it actually is received by the intended
recipient. Either Party may change the address to which notices, requests,
demands, claims, and other communications hereunder are to be delivered by
giving the other Party notice in the manner herein set forth.

     12.8  Governing Law. This Agreement shall be exclusively governed by and
construed in accordance with the domestic laws of the State of California
without giving effect to any choice or conflict of law provision or rule
(whether of the State of California or any other jurisdiction) that would cause
the application of the laws of any jurisdiction other than the State of
California.

     12.9  Amendments and Waivers. No amendment of any provision of this
Agreement shall be valid unless the same shall be in writing and signed by Buyer
and Seller.

     12.10 Severability. Any term or provision of this Agreement that is invalid
or unenforceable in any situation in any jurisdiction shall not affect the
validity or enforceability of the remaining terms and provisions hereof or the
validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction.

     12.11 Expenses. Whether or not the Acquisition is consummated, all fees and
expenses incurred in connection with the Acquisition including, without
limitation, all legal, accounting, financial advisory, consulting and all other
fees and expenses of third parties incurred by a Party in connection with the
negotiation and effectuation of the terms and conditions of this Agreement and
the transactions contemplated hereby, shall be the obligation of the respective
Party incurring such fees and expenses.

                                                                            -16-

     12.12  Construction. The Parties have participated jointly in the
negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise favoring or disfavoring either Party by virtue of the authorship of any of
the provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean "including without limitation." The word "agreement"
when used herein shall be deemed in each case to mean any contract, commitment
or other agreement, whether oral or written, that is legally binding. Without
limiting the generality of the foregoing, the mere listing (or inclusion of a
copy) of a document or other item shall not be deemed adequate to disclose an
exception to a representation or warranty made herein (unless the representation
or warranty has to do with the existence of the document or other item itself).
The Parties intend that each representation, warranty and covenant contained
herein shall have independent significance. If either Party has breached any
representation, warranty or covenant contained herein in any respect, the fact
that there exists another representation, warranty or covenant relating to the
same subject matter (regardless of the relative levels of specificity) which the
Party has not breached shall not detract from or mitigate the fact that the
Party is in breach of the first representation, warranty or covenant.

     12.13  Incorporation of Exhibits and Schedules. The Exhibits and Schedules
identified in this Agreement are incorporated herein by reference and made a
part hereof.

     12.14  Other Remedies. Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a Party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon
such Party, and the exercise by a Party of any one remedy will not preclude the
exercise of any other remedy.

     12.15  Submission to Jurisdiction. Each of the Parties irrevocably consents
to the exclusive jurisdiction and venue of any state or federal court sitting in
Santa Clara County, California, in any action or proceeding arising out of or
relating to this Agreement and agrees that all claims in respect of the action
or proceeding may be heard and determined in any such court. Each of the Parties
waives any defense of inconvenient forum to the maintenance of any action or
proceeding so brought and waives any bond, surety, or other security that might
be required of any other party with respect thereto. Each Party agrees that a
final judgment in any action or proceeding so brought shall be conclusive and
may be enforced by suit on the judgment or in any other manner provided by law
or in equity.

                                                                            -17-

                (c)    All insurance policies in force with respect to Seller

                (d)    All judgments, awards or pending lawsuits, actions,
proceedings or litigation affecting the Acquired Assets with a brief description
of their nature or amounts:

         In November 2001, a complaint captioned Richmon v. Integrated Telecom
Express, Inc., No. 01-CV-10108 was filed in federal district court for the
Southern District of New York, on behalf of a putative class of persons who
purchased Seller's common stock between August 18, 2000 and December 6, 2000. An
amended complaint was filed in April 2002. The amended complaint generally
alleges that various investment bank underwriters engaged in improper and
undisclosed activities related to the allocation of shares in Seller's initial
public offering of securities and subsequently issued false and misleading
analyst reports. The complaint brings claims for violation of several provisions
of the Securities Act of 1933 and the Securities Exchange Act of 1934 against
those underwriters and also against Seller and various of Seller's present and
former officers and directors. Similar lawsuits concerning more than 300 other
companies' initial public offerings have been filed and coordinated as In re
Initial Public Offering Securities Litigation, No. 21 MC 92. Seller believes
that the claims against Seller are without merit and intends to defend this
lawsuit vigorously. While the outcome of these claims is currently not
determinable, Seller does not expect that the ultimate costs to resolve these
claims will have a material adverse effect on Seller's financial position,
results of operations or cash flows.

         In addition to the lawsuit mentioned above, from time to time, Seller
may become involved in litigation relating to claims arising from its ordinary
course of business. Seller is not currently a party to any material legal
proceeding of this nature.

                                                                             E-1
