         and Ajit Deora, the agreements referred to therein and the retention
         bonus program established in connection therewith.

         Section 2.3. TRANSFERS NOT EFFECTED ON OR PRIOR TO THE SEPARATION DATE.
To the extent any transfers contemplated by this Article II shall not have been
fully effected on or before the Separation Date, Phoenix and inSilicon shall
cooperate to effect such transfers as promptly as possible following the
Separation Date. Nothing herein shall be deemed to require the transfer of any
assets or the assignment or assumption of any Liabilities that by their terms or
by operation of law cannot be so transferred, assigned or assumed; PROVIDED,
HOWEVER, that any such asset shall be deemed a Semiconductor Intellectual
Property Asset for purposes of determining whether any Liability is a inSilicon
Liability or any benefit received related to the Business and should be held for
the benefit of inSilicon; and PROVIDED, FURTHER, that Phoenix and inSilicon and
their respective Affiliates shall cooperate in seeking to obtain any necessary
Consents for the transfer of all assets and the assignment or assumption of all
Liabilities as contemplated by this Article II. In the event that any transfer
of assets or assignment or assumption of Liabilities contemplated by this
Article II has not been consummated effective as of the Separation Date, (a) the
party retaining such assets shall thereafter hold such assets in trust for the
use and benefit of the party entitled thereto (at the expense of the party
entitled thereto); and (b) the party retaining such Liabilities shall thereafter
hold such Liabilities for the account of the party assuming such Liability or to
whom such Liability is to be assigned pursuant hereto (at the expense of the
party assuming such Liability or to whom such Liability is to be assigned), and
in each such case shall take such other actions as it may be commercially
reasonable for the Person to whom such asset is to be transferred to request in
order to place such Person, insofar as reasonably possible, in the same position
as if such asset had been transferred as contemplated hereby and so that all the
benefits and burdens relating to such Semiconductor Intellectual Property Assets
(or such Non-Semiconductor Intellectual Property Assets, as the case may be),
including possession, use, revenue, risk of loss, potential for gain, and
dominion, control and command over such assets, are to inure from and after the
Separation Date to inSilicon (or the Phoenix Group, as the case may be). As and
when any such asset or Liability becomes transferable, assignable or assumable,
as the case may be, such transfer, assignment or assumption, as the case may be,
shall be effected forthwith. Phoenix and inSilicon agree that, as of the
Separation Date, each party hereto shall be deemed to have acquired complete and
sole beneficial ownership over all of the assets, together with all of the
rights, powers and privileges incidental thereto, that such party is entitled to
acquire pursuant to the terms of this Agreement.

         Section 2.4. NO REPRESENTATIONS OR WARRANTIES; CONSENTS. (a) Each of
the parties hereto understands and agrees that no party hereto is, in this
Agreement representing or warranting in any way as to the value or freedom from
encumbrance of, or any other matter concerning, any assets of such party, or as
to the legal sufficiency to convey title to an asset transferred pursuant to
this Agreement, including, without limitation, any conveyancing or assumption
instruments. It is also agreed and understood that there are no warranties
whatsoever, express or implied, given by either party to this Agreement, as to
the condition, quality, merchantability or fitness of any of the assets,
businesses or other rights transferred or retained by the parties, as the case
may be, and all such assets, businesses and other rights shall be "as is, where
is" and "with all faults" (provided that the absence of warranties given by the
parties shall not negate the allocation of Liabilities under this Agreement and
shall have no effect on any manufacturers, sellers, or other third party
warranties that are intended to be transferred


                                      7
<PAGE>

with such assets), and inSilicon shall bear the economic and legal risks that
any conveyance shall prove to be insufficient to vest in it good and
marketable title, free and clear of any security interest, pledge, lien,
charge, claim, option, right to acquire, covenant, condition, restriction on
transfer or other encumbrance of any nature whatsoever. Notwithstanding the
foregoing, Phoenix represents and warrants to inSilicon that it has good and
marketable title to the Intellectual Property listed on Schedule 2.4(a).

         (b) Each party hereto understands and agrees that no party hereto is,
in this Agreement or any other agreement or document contemplated by this
Agreement or otherwise, representing or warranting in any way that the obtaining
of any Consents, the execution and delivery of any amendatory agreements and the
taking of any filings or applications contemplated by this Agreement will
satisfy the provisions of any or all applicable laws or judgments or other
instruments or agreements relating to such assets.

         Notwithstanding the foregoing, the parties shall use commercially
reasonable efforts in the United States (and best efforts in jurisdictions
outside the United States) to obtain all Consents (including such Consents as
may be required by any Governmental Authority). The parties shall also use
commercially reasonable efforts to make all filings and applications
contemplated by this Agreement, and shall take all such further actions as shall
be deemed reasonably necessary to preserve for each of Phoenix and inSilicon, to
the greatest extent reasonably feasible, consistent with this Agreement, the
economic and operational benefits of the allocation of assets and liabilities
provided for in this Agreement.

         Section 2.5. DOCUMENTS RELATING TO TRANSFER OF ASSETS AND ASSIGNMENT
AND ASSUMPTION OF LIABILITIES. In connection with the transfer of the
Semiconductor Intellectual Property Assets pursuant to Section 2.1 of this

         Section 3.2. REPRESENTATIONS AND WARRANTIES OF PHOENIX; LEGENDS. (a)
Phoenix hereby represents and warrants to inSilicon that:

                  (i)   The Securities to be acquired by Phoenix will be
         acquired for investment for Phoenix's own account, and not with a
         view to the resale or distribution of any part thereof, and that
         Phoenix has no present intention of selling, granting any
         participation in, or otherwise distributing the same in a manner
         contrary to applicable laws.

                  (ii)  The Securities have not been registered under the
         Securities Act, by reason of a specific exemption from the registration
         provisions of the Securities Act which depends upon, among other
         things, the bona fide nature of the investment intent and the accuracy
         of Phoenix's representations as expressed herein. Phoenix understands
         that the Securities are "restricted securities" under applicable U.S.
         federal and state securities laws and that, pursuant to these laws,
         Phoenix must hold the Securities indefinitely unless they are
         registered with the Securities and Exchange Commission and qualified by
         state authorities, or an exemption from such registration and
         qualification requirements is available.

         (b) LEGENDS. Phoenix understands that the Securities and any securities
issued in respect of or exchange for the Securities, may bear one or all of the
following legends:

         BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN
         ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION
         WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION
         MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED
         THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO INSILICON
         THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF
         1933."

                  (ii)  Any legend required by the Blue Sky laws of any state
         to the extent such laws are applicable to the shares represented by

                                   ARTICLE IV

                              RIGHT OF FIRST OFFER

         Section 4.1. GRANT OF RIGHT OF FIRST OFFER. Subject to the terms and
conditions specified in this Article IV, inSilicon hereby grants to Phoenix a
right of first offer with respect to future sales by inSilicon of inSilicon
Capital Stock. As long as Phoenix owns 50,000 shares of Series A Preferred Stock
(or the Common Stock issued upon conversion thereof) Phoenix may designate as
purchasers under such right itself or its Affiliates in such proportions as it
deems appropriate.

         Section 4.2. TERMS OF OFFER AND PURCHASE. Each time inSilicon proposes
to offer any shares of inSilicon Capital Stock, inSilicon shall first make an
offering of such inSilicon Capital Stock to Phoenix in accordance with the
following provisions:

         (a) inSilicon shall deliver a notice (the "Notice") to Phoenix stating
(i) its bona fide intention to offer such inSilicon Capital Stock, (ii) the
number of shares of such inSilicon Capital Stock to be offered, and (iii) the
price and terms, if any, upon which it proposes to offer such inSilicon Capital
Stock.

         (b) Within fifteen (15) calendar days after delivery of the Notice,
Phoenix may elect to purchase or obtain, at the price and on the terms specified
in the Notice, up to that portion of such inSilicon Capital Stock which equals
the proportion that the number of shares of Common Stock issued and held, or
issuable upon conversion and exercise of all convertible or exercisable
securities then held, by Phoenix bears to the total number of shares of Common
Stock then outstanding (assuming full conversion and exercise of all options,
warrants and convertible or exercisable securities). Such purchase shall be
completed at the same closing as that of any third party purchasers or at an
additional closing thereunder.

         (c) inSilicon may, during the forty five (45)-day period following the
expiration of the period provided in Section 4.2(b) hereof, offer the remaining
unsubscribed portion of the inSilicon Capital Stock to any Person or Persons at
a price not less than, and upon terms no more favorable to the offeree than
those specified in the Notice. If inSilicon does not enter into a Memorandum of
Understanding ("MOU") for the sale of the inSilicon Capital Stock within such
period, or if such agreement is not consummated within sixty (60) days following
the execution


                                      10
<PAGE>

of the MOU, the right provided hereunder shall be deemed to be revived and
such Stock shall not be offered unless first reoffered to Phoenix in
accordance herewith.

         (d) The right of first offer in this Article IV shall not be applicable
(i) to the issuance or sale of 2,700,000 shares of Common Stock (or options
therefor) to employees, consultants or directors pursuant to the 1999 Employee
Stock Option Plan approved by the Board of Directors; (ii) to the issuance of
securities in connection with a bona fide business acquisition of or by
inSilicon, whether by merger, consolidation, sale of assets, sale or exchange of
stock or otherwise; (iii) to the issuance of securities to financial
institutions or lessors in connection with commercial credit arrangements,
equipment financings, or similar transactions; (iv) to the shares issued upon
the conversion of the Series A Preferred Stock; (v) to the securities issued
pursuant to or after consummation of a Qualified IPO; (vi) to the issuance of
securities pursuant to the Warrant; or (vii) to securities issued pursuant to
stock splits, stock dividends or similar transactions.

                                   BRIDGE LOAN

         Section 5.1. REQUEST FOR ADVANCE. If from time to time prior to a
Qualified IPO, the Liabilities of inSilicon then due and payable shall exceed
its cash and cash equivalents (as determined under GAAP), inSilicon may require
Phoenix to provide to inSilicon up to an amount of cash equal to the amount by
which such Liabilities exceed such cash and cash equivalents (a "Shortfall
Amount") by delivering a request therefor to Phoenix (a "Shortfall Request").

         Section 5.2. ADVANCES BY INSILICON. Within two (2) business days after
delivery of a Shortfall Request, Phoenix shall deposit or cause to be deposited
into an account designated by inSilicon the Shortfall Amount set forth in the
Shortfall Request in immediately available funds.

         Section 5.3. INTEREST. Amounts advanced by Phoenix under Section 5.2
shall bear interest at the rate of 8% per annum, computed from the date of
deposit in the applicable inSilicon account to the date of repayment to Phoenix.

         Section 5.4. REPAYMENT. The principal amounts advanced by Phoenix under
Section 5.2 and/or interest thereon under Section 5.3 may be paid by inSilicon
to Phoenix at any time and from time to time, in whole or in part; PROVIDED,
THAT, all principal and interest that remains outstanding as of the date of the
closing of a Qualified IPO shall become due and payable to Phoenix concurrent
with the closing of the Qualified IPO.

waiver of any terms, provision or condition of or failure to exercise or delay
in exercising any rights or remedies under this Agreement, in any one or more
instances shall be deemed to be, or construed as, a further or continuing waiver
of any such term, provision, condition, right or remedy or as a waiver of any
other term, provision or condition of this Agreement. Notwithstanding the
foregoing, this Agreement may not be altered or amended, nor may rights
hereunder be waived by inSilicon after the closing of a Qualified IPO without
the affirmative vote or written consent of a majority of the directors of
inSilicon who are not Affiliates of Phoenix.

         Section 6.4. COUNTERPARTS. This Agreement may be executed in

accordance with, and governed by, the laws of the State of California, without
regard to the conflicts of law rules of such state.

         Section 6.6. ENTIRE AGREEMENT. This Agreement including the schedules

party which shall not be unreasonably withheld. This Agreement shall be
binding upon, and shall inure to the benefit of, the parties hereto and their

remedies upon any Person other than Phoenix and inSilicon.

which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof. Any such
prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction. Without prejudice
to any rights or remedies otherwise available to any party hereto, each party
hereto acknowledges that damages would be an inadequate remedy for any breach of
the provisions of this Agreement and agrees that the obligations of the parties
hereunder shall be specifically enforceable.
