                                REORGANIZATION

     This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made and
entered into as of October 5, 2000 by and among Centillium Communications, Inc.,
a Delaware corporation ("Parent"), Eugene Acquisition Corp., a Delaware
corporation and a wholly-owned subsidiary of Parent ("Sub"), vEngines, Inc., a
Delaware corporation (the "Company"), and the Principal Stockholders, as defined
below).

                                  BACKGROUND

     A.   The Boards of Directors of each of Parent, Sub and the Company believe
it is in the best interests of their respective companies and the stockholders
of their respective companies that Parent acquire the Company through the
statutory merger of Sub with and into the Company (the "Merger") and, in
furtherance thereof, have approved the Merger.

     B.   Pursuant to the Merger, among other things, all of the issued and
outstanding capital stock of the Company shall be converted into the right to
receive the consideration upon the terms and conditions set forth herein.

     C.   The Company, on the one hand, and Parent and Sub, on the other hand,
desire to make certain representations, warranties, covenants and other
agreements in connection with the Merger.

     D.   Concurrently with the execution and delivery of this Agreement, as
material inducements to Parent and Sub to enter into this Agreement, (i) certain
stockholders of the Company (the "Principal Stockholders") are entering into a
Voting Agreement, in the form attached as Exhibit A (the "Company Voting
                                          ---------
Agreement"), with Parent, and (ii) certain key employees of the Company are
entering into Noncompetition Agreements, in the form attached as Exhibit B (the
                                                                 ---------
"Noncompetition Agreements").

     E.   The parties intend, by executing this Agreement, to adopt a plan of
reorganization within the meaning of Section 368 of the Internal Revenue Code of
1986, as amended (the "Code").

     NOW, THEREFORE, the parties agree as follows:
<PAGE>

     1.1  The Merger.  At the Effective Time (as defined below) and subject to
and upon the terms and conditions of this Agreement and the applicable
provisions of the Delaware General Corporation Law (the "Delaware Law"), Sub
shall be merged with and into the Company, the separate corporate existence of
Sub shall cease and the Company shall continue as the surviving corporation and
as a wholly-owned subsidiary of Parent. The surviving corporation after the
Merger is sometimes referred to as the "Surviving Corporation."

     1.2  Effective Time.  Unless this Agreement is terminated earlier pursuant
          --------------
to Section 8.1, the closing of the Merger (the "Closing") will take place within
two (2) business days, subject to the provisions set forth in Section 8.1(e),
following satisfaction or waiver of the conditions set forth in Article VI
hereof, at the offices of Wilson Sonsini Goodrich & Rosati, Professional
Corporation, 650 Page Mill Road, Palo Alto, California, unless another time
and/or place is mutually agreed upon in writing by Parent and the Company. The
date upon which the Closing actually occurs shall be referred to as the "Closing
Date." On the Closing Date, the parties shall cause the Merger to be consummated
by filing an Certificate of Merger (or like instrument), in substantially the
form attached hereto as Exhibit C, with the Secretary of State of the State of
                        ---------
Delaware (the "Certificate of Merger"), in accordance with the applicable
provisions of Delaware Law (the time of acceptance by the Secretary of State of
the State of Delaware of such filing shall be referred to as the "Effective
Time").

     1.3  Effect of the Merger.  At the Effective Time, the effect of the Merger
          --------------------
shall be as provided in the applicable provisions of Delaware Law. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, except as otherwise agreed to pursuant to the terms of this Agreement, all
the property, rights, privileges, powers and franchises of the Company and Sub
shall vest in the Surviving Corporation, and all debts, liabilities and duties
of the Company and Sub shall become the debts, liabilities and duties of the
Surviving Corporation.

     1.4  Certificate of Incorporation and Bylaws.
          ---------------------------------------

          (a)  Unless otherwise determined by Parent prior to the Effective
Time, the Certificate of Incorporation of Sub shall be amended and restated as
set forth in Exhibit D, and shall be the Certificate of Incorporation of the
             ---------
Surviving Corporation at the Effective Time until thereafter amended in
accordance with Delaware Law and as provided in such Certificate of
Incorporation, provided, that no such amendment or restatement shall diminish
any right of indemnification extended to the Company's current directors under
the Company's Certificate of Incorporation as in effect on the date hereof.

                                      -2-
<PAGE>

          (b)  Unless otherwise determined by Parent prior to the Effective
Time, the Bylaws of Sub, as in effect immediately prior to the Effective Time,
shall be the Bylaws of the Surviving Corporation at the Effective Time until
thereafter amended in accordance with Delaware Law and such Bylaws, provided,
that no right of indemnification extended to the directors or officers of the
Company incumbent as of the date hereof under the Bylaws of the Company as in
effect on the date hereof shall be curtailed or diminished thereby.

     1.5  Directors and Officers.  Unless otherwise determined by Parent prior
          ----------------------
to the Effective Time, the directors and officers of Sub immediately prior to
the Effective Time shall be the directors and officers of the Surviving
Corporation immediately after the Effective Time, in accordance with the
provisions of Delaware Law and the Certificate of Incorporation and Bylaws of
the Surviving Corporation, until their respective successors are duly elected or
appointed and qualified.

Transaction Stock Price shall be equal to the Signing Stock Price.

                      (2)   If the Closing Stock Price is greater than 1.1

the Closing Stock Price divided by 1.1.

                      (3)   If the Closing Stock Price is less than 0.9
multiplied by the Signing Stock Price, then the Transaction Stock Price shall be

               (iv)   "Closing Stock Price" is the average of the closing prices
on the Nasdaq National Market of the Parent Common Stock for the twenty (20)

          (d)  Assumption of Company Options to Purchase Common Capital Stock.
               --------------------------------------------------------------

               (i)    At the Effective Time, each Company Option, whether vested
or unvested, granted under the Plan shall be deemed to constitute an option (an
"Assumed Option") to acquire, on the same terms and conditions as were
applicable under the Company Option, a number of shares of Parent Common Stock
equal to the number of shares of Company Common Stock that could have been
purchased under the Company Option multiplied by the Exchange Ratio (with the
resulting number of shares being rounded to the nearest whole share), at a price
per share of Parent Common Stock equal to the option exercise price (rounded up
to the nearest whole cent) of the Company Option divided by the Exchange Ratio;
provided, however, that in the case of any
--------

                                      -5-
<PAGE>

Assumed Option to which Section 422 of the Code applies ("Incentive Stock
Options"), the option price, the number of shares purchasable pursuant to such
option and the terms and conditions of exercise of such options shall be
determined in order to comply with Section 424(a) of the code.

cash (rounded to the nearest whole cent) equal to the product of (i) such
fraction, multiplied by (ii) the Transaction Stock Price.

repurchase option by the Company, risk of forfeiture or other condition under

only be entitled to such rights as are provided by Delaware Law, and, to the
extent applicable in accordance with California law.

          (b)  Notwithstanding the provisions of Section 1.8(a) hereof, if any
holder of Dissenting Shares shall effectively withdraw or lose (through failure
to perfect or otherwise) such holder's appraisal rights under Delaware Law, and,
to the extent applicable in accordance with California law, then, as of the
later of the Effective Time and the occurrence of such event, such holder's

provided, however, that on behalf of the Stockholders, Parent shall deposit into
the Escrow Fund (as defined in Section 7.2(b)) a number of shares of Parent

Escrow Amount out of the aggregate number of shares of Parent Common Stock
otherwise issuable to the Stockholders pursuant to Section 1.6.

          (c)  Exchange Procedures. As promptly as practicable after the
               -------------------

deemed from and after the Effective Time, for all corporate purposes other than
the payment of dividends, to evidence the ownership of the number of full shares
of Parent Common Stock into which such shares of Company Capital Stock shall
have been so converted. To the extent all outstanding original stock
certificates of the Company are delivered at Closing, Parent shall forward such
stock certificates directly to the Exchange Agent for cancellation, and in
exchange therefor shall issue certificate(s) representing the applicable number
of whole shares of Parent Common Stock.

          (d)  Distributions With Respect to Unexchanged Shares. No dividends or
               ------------------------------------------------
other distributions declared or made after the Effective Time with respect to
Parent Common Stock with a record date after the Effective Time will be paid to
the holder of any unsurrendered Certificates with respect to the shares of

to the record holder thereof, without interest, certificate(s) representing
whole shares of Parent Common Stock issued in exchange therefor.

          (e)  Transfers of Ownership. If any certificate for shares of Parent

issuance thereof that the Certificates so surrendered will be properly endorsed

other taxes required by reason of the issuance of a certificate for shares of

agent designated by it that such tax has been paid or is not payable.

Certificate pursuant to Section 1.9(c) prior to that time, shall be delivered to

          ----------------------------------------------------
Parent Common Stock paid in respect of the surrender for exchange of shares of
Company Capital Stock in accordance with the terms hereof (including any cash

to be full satisfaction of all rights pertaining to such shares of Company
Capital Stock, and there shall be no further registration of transfers on the
records of the Surviving Corporation of shares of Company Capital Stock which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates are presented to the Surviving Corporation for any
reason, they shall be canceled and exchanged as provided in this Article I.

   1.11   Lost, Stolen or Destroyed Certificates.  In the event any certificates
          --------------------------------------
evidencing shares of Company Capital Stock shall have been lost, stolen or
destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or
destroyed certificates, upon the making of an affidavit of that fact by the

necessary to correct any statement in any earlier communication with respect to

delivered by the Principal Stockholder (excluding those entered into as an
authorized and qualified representative on behalf of the Company) in connection
with the Merger and the transactions contemplated thereby to which the Principal
Stockholder is a party or otherwise bound.

      (b)   Escrow Fund.  As security for the indemnity provided for in Section
            -----------
7.2(a) above and by virtue of this Agreement and the Certificate of Merger, the
Company and the Escrow Stockholders will be deemed to have received (subject to
the conditions of this Section 7.2) and deposited with the Escrow Agent the
Escrow Amount (plus any additional shares as may be issued in respect of any
stock split, stock dividend or recapitalization effected by Parent after the
Effective Time with respect to the Escrow Amount) without any act of the Company
or the Escrow Stockholders.  The Escrow Amount shall be available to compensate
the Indemnified Parties for any claims by such Parties for any Losses suffered
or incurred by them and for which they are entitled to

                                     -51-
<PAGE>

recovery under this Article VII. As promptly as practicable after the Effective
Time, the Escrow Amount, without any act of the Escrow Stockholders, will be
deposited with Imperial Bank, as Escrow Agent (or other institution acceptable
to Parent and the Stockholder Representative (as defined in Section 7.2(h) below
and the preamble above)), such deposit of the Escrow Amount to constitute an
escrow fund (the "Escrow Fund") to be governed by the terms set forth herein.
The Escrow Agent may execute this Agreement following the date hereof and prior
to the Effective Time, and such later execution, if so executed after the date
hereof, shall not affect the binding nature of this Agreement as of the date
hereof between the other signatories hereto. Notwithstanding any provision of
this Agreement to the contrary (except as set forth in Section 5.5 and 7.2(m)),
after the Effective Time, no Indemnified Party shall be entitled to
indemnification or to obtain any proceeds from the Escrow Fund or to otherwise
recover any amount unless and until one or more Officer's Certificate (as
defined in Section 7.2(e) below) identifying Losses in excess of $100,000 in the
aggregate (the "Basket Amount") has or have been delivered to the Escrow Agent
as provided in Section 7.2(e) below, in which case, subject to subsections (f)
and (g) of this Section 7.2, an Indemnified Party shall be entitled to recover
all Losses including the Basket Amount; provided, however, legal fees incurred
by the Stockholder Representative to the extent set forth in Section 7.2(h)(ii)
and indemnity claims of the stockholder Representative thereunder, as provided
in Section 7.2(m), and any amounts required to be paid by the Parent or the
Surviving Corporation holders of Company Capital Stock with respect to
Dissenting Shares, shall not be subject to such Basket Amount.

     (c)  Escrow Period; Distribution upon Termination of Escrow Period. Subject
          -------------------------------------------------------------
to the following requirements, the Escrow Fund shall be in existence immediately
following the Effective Time and shall terminate at 5:00 p.m., P.D.T., on the
day prior to the 12-month anniversary of the Closing Date (the "Escrow Period"),
at which time the Escrow Agent shall distribute the Escrow Fund to the Escrow
Stockholders; provided, however, that the Escrow Period shall not terminate with
respect to, and the Escrow Agent shall retain in the Escrow Fund, any amount
which, in the reasonable judgment of Parent is necessary to satisfy any then
pending and unsatisfied claims specified in any Officer's Certificate (as
defined in Section 7.2(e)(i) delivered to the Escrow Agent (and to the
Stockholder Representative pursuant to Section 7.2(f)) prior to 12-month
anniversary of the Closing Date the with respect to facts and circumstances
existing prior to the 12-month anniversary of the Closing Date.  As soon as all
such claims have been resolved, the Escrow Agent shall deliver to the Escrow
Stockholders the remaining portion of the Escrow Fund, if any, not required to
satisfy such claims. Deliveries of Escrow Amounts to the Escrow Stockholders
pursuant to this Section 7.2(c) shall be made in proportion to their respective
original contributions to the Escrow Fund as determined pursuant to Section
1.9(b).

     (d)  Protection of Escrow Fund; Distribution of Interest from Escrow Fund.
          --------------------------------------------------------------------

           (i)  The Escrow Agent shall hold and safeguard the Escrow Fund during
the Escrow Period, shall treat such fund as a trust fund in accordance with the
terms of this Agreement and not as the property of Parent and shall hold and
dispose of the Escrow Fund only in accordance with the terms hereof and of the
Escrow Agreement.

                                     -52-
<PAGE>

          (ii)   Any shares of Parent Common Stock or other equity securities
issued or distributed by Parent (including shares issued upon a stock split)
("New Shares") in respect of Parent Common Stock in the Escrow Fund which have
not been released from the Escrow Fund shall be added to the Escrow Fund and
become a part thereof.  New Shares issued in respect of shares of Parent Common
Stock which have been released from the Escrow Fund shall not be added to the
Escrow Fund but shall be distributed to the record holders thereof.  Cash
dividends on Parent Common Stock shall not be added to the Escrow Fund but shall
be distributed to the record holders thereof.

          (iii)  Each Escrow Stockholder shall have voting rights and the right
to distributions of dividends with respect to the shares of Parent Common Stock
contributed to the Escrow Fund by such Escrow Stockholder (and on any voting
securities added to the Escrow Fund in respect of such shares of Parent Common
Stock), as determined pursuant to Section 1.9(b).

     (e)  Claims Upon Escrow Fund.
          -----------------------

          (i)    Upon receipt by the Escrow Agent at any time on or before the
before the last date of the Escrow Period of a certificate signed by any officer
of Parent (an "Officer's Certificate"): (A) stating that an Indemnified Party
has paid, sustained or properly accrued or reasonably anticipates that it will
have to pay, sustain or accrue Losses in a stated amount, and (B) specifying in
reasonable detail the individual items of Losses included in the amount so
stated, the date each such item was paid, sustained or properly accrued, or the
basis for such anticipated liability, and the nature of the misrepresentation,
breach of warranty or covenant or other indemnity to which such item is related,
the Escrow Agent shall, subject to the provisions of Section 7.2(f) and Section
7.2(g) below, deliver to the Indemnified Party out of the Escrow Fund, as
promptly as practicable, shares of Parent Common Stock held in the Escrow Fund
in an amount equal to such Losses. Shares of the Escrow Stockholders contributed
to the Escrow Fund in accordance with Section 1.9(b) shall be delivered to
Parent out of the Escrow Fund pro rata based on each Escrow Stockholder's
contribution to the Escrow Fund.

          (ii)   For the purposes of determining the number of shares of Parent
Common Stock to be delivered to an Indemnified Party out of the Escrow Fund
pursuant to this Article VII, the shares of Parent Common Stock shall be valued
at the Transaction Stock Price.

     (f)  Objections to Claims.  At the time of delivery of any Officer's
          --------------------
Certificate to the Escrow Agent, a duplicate copy of such certificate shall be
delivered to the Stockholder Representative and for a period of 30 days after
such delivery, the Escrow Agent shall make no delivery to any Indemnified Party
of any Escrow Amounts pursuant to Section 7.2(e)(i) or any other provision
hereof. After the expiration of such 30-day period, the Escrow Agent shall make
delivery of shares of Parent Common Stock from the Escrow Fund in accordance
with Section 7.2(e) hereof, provided that no such payment or delivery may be
made if the Stockholder Representative shall object in a written statement to
the claim made in the Officer's Certificate, and such statement shall have been
delivered to the Escrow Agent prior to the expiration of such 30-day period.

                                     -53-
<PAGE>

     (g)  Resolution of Conflicts; Arbitration.
          ------------------------------------

          (i)   In case the Stockholder Representative shall object in writing
to any claim or claims made in any Officer's Certificate within 30 days after
delivery of such Certificate, the Stockholder Representative and Parent shall
attempt in good faith to agree upon the rights of the respective parties with
respect to each of such claims. If the Stockholder Representative and Parent
should so agree, a memorandum setting forth such agreement shall be prepared and
signed by both parties and delivered to the Escrow Agent. The Escrow Agent shall
be entitled to rely on such memorandum and distribute shares of Parent Common
Stock from the Escrow Fund in accordance with the terms thereof.

          (ii)  If no such agreement can be reached after good faith
negotiation, either Parent or the Stockholder Representative may after ten (10)
business days demand arbitration of the matter; provided, however, that if the
amount of the Loss at issue is the subject of pending litigation with a third
party, arbitration shall not be commenced until (A) such amount is ascertained
or (B) both parties agree to arbitration. In either such event the matter shall
be settled by binding arbitration in San Jose, California under the American
Arbitration Association (the "AAA") International Arbitration Rules and
Supplemental Procedures for Large Complex Disputes. A single, neutral arbitrator
(the "Arbitrator") shall be appointed by the AAA within ten (10) days after the
demand is submitted for arbitration. The parties shall have seven (7) days to
object in writing to the appointment of the Arbitrator, the sole basis for
objection being an actual conflict of interest. The AAA, in its sole discretion,
shall determine within seven (7) days the validity of any objection to the
appointment of the Arbitrator based on an actual conflict of interest. The
parties shall use their commercially reasonable efforts to cooperate with each
other in causing the arbitration to be held in as efficient and expeditious a
manner as practicable, including but not limited to, providing such documents
and making available such of their personnel as the Arbitrator may request, so
that the Arbitrator's decision on the matter may be timely. The Arbitrator shall
have the power to decide all questions of arbitrability. The Arbitrator shall
render a decision on the matter within fifty (50) days after being appointed to
serve as Arbitrator, unless the parties otherwise agree in writing or the
Arbitrator makes a finding that the party has carried the burden of showing good
cause for a longer period. The parties to the arbitration may apply to any court
of competent jurisdiction for a temporary restraining order, preliminary
injunction or other interim or conservatory relief, as necessary, without breach
of this arbitration provision and without any abridgement of the powers of the
Arbitrator, but shall not otherwise have the right to remove the proceeding to a
court of law or equity or supersede the arbitration by a judicial proceeding
except by mutual consent. The parties hereto agree that, any provision of
applicable law notwithstanding, they will not request and the Arbitrator shall
have no authority to award punitive or exemplary damages against any party.
Judgment on the award rendered by the Arbitrator may be entered in any court
having jurisdiction thereof. The Escrow Agent shall be entitled to act in
accordance with such judgment and make or withhold payments out of the Escrow
Fund in accordance therewith. The Arbitrator may award to the prevailing party,
if any, as determined by the Arbitrator, all of its reasonable costs and fees,
including without limitation AAA administrative fees, Arbitrator fees and
attorney's fees.

     (h)  Stockholder Representative of the Stockholders; Power of Attorney.
          -----------------------------------------------------------------

          (i)   In the event that the Merger is approved, effective upon such
vote, and without the further act of any Stockholder, Tushar Dave shall be
appointed as agent and attorney-in-fact for each Stockholder (except such
Stockholders, if any, as shall have perfected their appraisal or dissenters'
rights under Delaware Law), for and on behalf of the Stockholders, to give and
receive notices and communications, to authorize delivery to an Indemnified
Party of shares of Parent Common Stock from the Escrow Fund in satisfaction of
claims by an Indemnified Party, to object to such deliveries, to agree to,
negotiate, enter into settlements and compromises of, and demand arbitration and
comply with orders of courts and awards of arbitrators with respect to such
claims, and to take all actions necessary or appropriate in the judgment of
Stockholder Representative for the accomplishment of the foregoing.  The
Stockholder Representative shall have the right to resign and such agency may be
changed by the Stockholders from time to time upon not less than 30 days prior
written notice to Parent; provided, however, that the Stockholder Representative
may not be removed unless holders of a majority in interest of the Escrow Fund
agree to such removal and to the identity of the substituted agent.  Any vacancy
in the position of Stockholder Representative may be filled by approval of the
holders of a majority in interest of the Escrow Fund.  No bond shall be required
of the Stockholder Representative, and the Stockholder Representative shall not
receive compensation for his or her services, except as shall be approved by the
majority in interest of the Escrow Stockholders pursuant to Section 7.2(m), from
amounts distributed from the Escrow Fund thereunder.  Notices or communications
to or from the Stockholder Representative shall constitute notice to or from
each of the Stockholders.

          (ii)  The Stockholder Representative shall not be liable for any act
done or omitted hereunder as Stockholder Representative while acting in good
faith and in the exercise of reasonable judgment.  The Stockholder
Representative shall have the right to retain and consult legal counsel and any
act done or omitted by the Stockholder Representative pursuant to the advice of
counsel shall be deemed in good faith and reasonable judgment.  The Escrow
Stockholders on whose behalf the Escrow Amount was contributed to the Escrow
Fund shall severally indemnify from the Escrow Fund as provided in Section
7.2(m) the Stockholder Representative and hold the Stockholder Representative
harmless against any loss, liability or expense incurred without negligence or
bad faith on the part of the Stockholder Representative and arising out of or in
connection with the acceptance or administration of the Stockholder
Representative's duties hereunder, including the reasonable fees and expenses of
any legal counsel retained by the Stockholder Representative not to exceed an
aggregate of 1/21 of the Escrow Amount.

     (i)  Actions of the Stockholder Representative.  A decision, act, consent
          -----------------------------------------
or instruction of the Stockholder Representative authorized hereunder, including
but not limited to an extension or waiver of this Agreement pursuant to Section
8.4 hereof, shall constitute a decision of all the Stockholders and shall be
final, binding and conclusive upon each such Stockholder, and the Escrow Agent
and Parent may rely upon any such decision, act, consent or instruction of the
Stockholder Representative as being the decision, act, consent or instruction of
each and every such Stockholder.  The Escrow Agent and Parent (and any
Indemnified Party) are hereby relieved from

                                     -55-
<PAGE>

any liability to any person for any acts done by them in accordance with such
decision, act, consent or instruction of the Stockholder Representative.

     (j)  Third-Party Claims.  In the event Parent becomes aware of a third
          ------------------
party claim which Parent believes may result in a demand against the Escrow
Fund, Parent shall notify the Stockholder Representative of such claim, and the
Stockholder Representative, as representative for the Escrow Stockholders, shall
be entitled, at its expense, to participate in, but not to determine or conduct,
the defense of such claim. Parent shall have the right in its sole discretion to
conduct the defense of and settle any such claim; provided, however, that except
with the written consent of the Stockholder Representative, no settlement of any
such claim with third party claimants shall be determinative of the amount of
Losses relating to such matter. In the event that the Stockholder Representative
has consented to any such settlement, neither the Stockholder Representative nor
any of the Escrow Stockholders shall have the power or authority to object under
any provision of this Article VII to the amount of any claim by Parent against
the Escrow Fund with respect to such settlement.

     (k)  Escrow Agent's Duties.
          ---------------------

          (i)    The Escrow Agent shall be obligated only for the performance of
such duties as are specifically set forth herein, and as set forth in any
additional written escrow instructions consistent with this Agreement which the
Escrow Agent may receive after the date of this Agreement which are signed by an
officer of Parent and the Stockholder Representative, and may rely and shall be
protected in relying or refraining from acting on any instrument reasonably
believed to be genuine and to have been signed or presented by the proper party
or parties.  The Escrow Agent shall not be liable for any act done or omitted
hereunder as Escrow Agent while acting in good faith and in the exercise of
reasonable judgment, and any act done or omitted pursuant to the advice of
counsel shall be conclusive evidence of such good faith.

          (ii)   The Escrow Agent is hereby expressly authorized to comply with
and obey orders, judgments or decrees of any court of law, notwithstanding any
notices, warnings or other communications from any party or any other person to
the contrary.  In case the Escrow Agent obeys or complies with any such order,
judgment or decree of any court, the Escrow Agent shall not be liable to any of
the parties hereto or to any other person by reason of such compliance,
notwithstanding any such order, judgment or decree being subsequently reversed,
modified, annulled, set aside, vacated or found to have been entered without
jurisdiction.

          (iii)  The Escrow Agent shall not be liable in any respect on account
of the identity, authority or rights of the parties executing or delivering or
purporting to execute or deliver this Agreement or any documents or papers
deposited or called for hereunder.

          (iv)   The Escrow Agent shall not be liable for the expiration of any
rights under any statute of limitations with respect to this Agreement or any
documents deposited with the Escrow Agent.

                                     -56-
<PAGE>

          (v)    In performing any duties under the Agreement, the Escrow Agent
shall not be liable to any party for damages, losses, or expenses, except for
gross negligence or willful misconduct on the part of the Escrow Agent.  The
Escrow Agent shall not incur any such liability for (A) any act or failure to
act made or omitted in good faith, or (B) any action taken or omitted in
reliance upon any instrument, including any written statement or affidavit
provided for in this Agreement that the Escrow Agent shall in good faith believe
to be genuine, nor will the Escrow Agent be liable or responsible for forgeries,
fraud, impersonations, or determining the scope of any representative authority.
In addition, the Escrow Agent may consult with the legal counsel in connection
with Escrow Agent's duties under this Agreement and shall be fully protected in
any act taken, suffered, or permitted by him/her in good faith in accordance
with the advice of counsel.  The Escrow Agent is not responsible for determining
and verifying the authority of any person acting or purporting to act on behalf
of any party to this Agreement.

          (vi)   If any controversy arises between the parties to this
Agreement, or with any other party, concerning the subject matter of this
Agreement, its terms or conditions, the Escrow Agent will not be required to
determine the controversy or to take any action regarding it. The Escrow Agent
may hold all documents and shares of Parent Common Stock and may wait for
settlement of any such controversy by final appropriate legal proceedings or
other means as, in the Escrow Agent's good faith discretion, the Escrow Agent
may be required, despite what may be set forth elsewhere in this Agreement. In
such event, the Escrow Agent will not be liable for damage. Furthermore, the
Escrow Agent may at its option, file an action of interpleader requiring the
parties to answer and litigate any claims and rights among themselves. The
Escrow Agent is authorized to deposit with the clerk of the court all documents
and shares of Parent Common Stock held in escrow, except all cost, expenses,
charges and reasonable attorney fees incurred by the Escrow Agent due to the
interpleader action and which the parties jointly and severally agree to pay.
Upon such action, the Escrow Agent shall be fully released and discharged of and
from all obligations and liability imposed by the terms of this Agreement.

          (vii)  The parties and their respective successors and assigns agree
jointly and severally to indemnify and hold Escrow Agent harmless against any
and all losses, claims, damages, liabilities, and expenses, including reasonable
costs of investigation, counsel fees, and disbursements that may be imposed on
Escrow Agent or incurred by Escrow Agent in connection with the performance of
its duties under this Agreement, including but not limited to any litigation
arising from this Agreement or involving its subject matter, other than arising
out of its negligence or willful misconduct.

          (viii) The Escrow Agent may resign at any time upon giving at least 30
days written notice to the parties; provided, however, that no such resignation
shall become effective until the appointment of a successor escrow agent which
shall be accomplished as follows: Parent and the Stockholder Representative
shall use their commercially reasonable efforts to mutually agree on a successor
escrow agent within 30 days after receiving such notice. If the parties fail to
agree upon a successor escrow agent within such time, the Escrow Agent shall
have the right to appoint a successor escrow agent authorized to do business in
the State of California. The successor escrow

                                     -57-
<PAGE>

agent shall execute and deliver an instrument accepting such appointment and it
shall, without further acts, be vested with all the estates, properties, rights,
powers, and duties of the predecessor escrow agent as if originally named as
escrow agent. The former Escrow Agent thereupon shall be discharged from any
further duties and liability under this Agreement.

          (l)  Fees.  All fees of the Escrow Agent for performance of its duties
               ----
hereunder shall be paid by Parent in accordance with the standard fee schedule
of the Escrow Agent.  It is understood that the fees and usual charges agreed
upon for services of the Escrow Agent shall be considered compensation for
ordinary services as contemplated by this Agreement.  In the event that the
conditions of this Agreement are not promptly fulfilled, or if the Escrow Agent
renders any service not provided for in this Agreement, or if the parties
request a substantial modification of its terms, or if any controversy arises,
or if the Escrow Agent is made a party to, or intervenes in, any litigation
pertaining to the Escrow Fund or its subject matter, the Escrow Agent shall be
reasonably compensated for such extraordinary services and reimbursed for all
costs, attorney's fees, and expenses occasioned by such default, delay,
controversy or litigation.

          (m)  Stockholder Representative Fees.  At the written request of the
               -------------------------------
Stockholder Representative, the Escrow Agent shall as promptly as practicable,
deliver to the Stockholder Representative, in his capacity as such, out of the
Escrow Fund, subject to the maximum aggregate amount of 1/21th of the Escrow
Amount, shares of Parent Common Stock held in the Escrow Fund in an amount equal
to the amount requested by the Stockholder Representative. The Stockholder
Representative shall deliver his written request to the Escrow Agent, with a
copy to Parent. The amount of such distribution shall not be subject to the
Basket Amount. At the request of the Stockholder Representative, Parent shall
facilitate and shall cause its transfer agent to facilitate the sale of the
shares so distributed in a broker's transaction at the market and shall allow
the proceeds thereof, net of costs of sale, to be delivered to the Stockholder
Representative. The Stockholder Representative shall hold the shares or proceeds
thereof so distributed in trust for distribution to the Escrow Stockholders pro
rata or for payment of applicable costs, fees or expenses at such time as the
Stockholder's Representative shall deem appropriate or as determined by vote of
the majority in interest of the Escrow Stockholders.

inaccuracies in the representations and warranties made to such party contained
herein or in any document delivered pursuant hereto, and (iii) waive compliance
with any of the agreements or conditions for the benefit of such party contained

signed by the Stockholder Representative shall be binding upon and effective
against all Stockholders (including the Principal Stockholders) whether or not
they have signed such extension or waiver.

(d) or (e), Parent will immediately invest $1,000,000 in the Company (the
"Parent Investment") pursuant to a convertible promissory note and a warrant,
which shall be on substantially the same terms as the ICICI Notes or, if there
are no ICICI Notes, then such convertible promissory note and warrant shall have
the principal terms set forth on Exhibit H (the "Convertible Note and Warrant")
                                 ---------
and shall be subject to documentation and other terms and conditions reasonably

          (b)  Within ten (10) days following the date of this Agreement, funds
for the Parent Investment (the "Investment Escrow Amount"), shall be deposited
with Imperial Bank, as the Investment Escrow Agent (or other institution
acceptable to Parent and Stockholder Representative), such deposit of the
Investment Escrow Amount to constitute an escrow fund (the "Investment Escrow
Fund") to be governed by terms set forth in Section 8.5(d).

          (c)  The Investment Escrow Amount shall be released to the Company
from the Investment Escrow Fund immediately upon the satisfaction of all of the
following conditions:

               (i)   The Parent shall have terminated this Agreement pursuant to
either Section 8.1(b), (c) (d) or (e).

               (ii)  There shall not have occurred any violation of the

Parent unless vetoed as provided therein), and such Convertible Note and Warrant
shall be in full force and effect.

true and correct as of such date) shall fail to be true and correct in all
material respects (except for representations and warranties qualified by
materiality which shall be correct in all respects) on and as of the date of
release of the Investment Escrow Fund as though such representations and
warranties were made on and as of the date of release of the Investment Fund,
then the Convertible Note and Warrant delivered in consideration of the Parent
Investment shall provide for a conversion discount (in the case of the note) and
the exercise price (in the case of the warrant) that is thirty percent (30%)
more favorable to Parent than to the corresponding terms in the ICICI Notes and

damages and the Parent shall have no further liability to the Company or any of
its stockholders, and the Company, the Indian Subsidiary and the Principal
Stockholders shall be released from all liability to Parent and Sub, in each
case under this Agreement except with respect to the surviving provisions hereof
as provided in Section 8.2.

          (g)  All interest accrued on the Investment Escrow Amount shall be
paid by the Investment Escrow Agent to the Parent upon release of the Investment
Escrow Fund.

<PAGE>

Investment Escrow Agent shall be considered compensation for ordinary services
as contemplated by this Agreement. In the event that the conditions of this
Agreement are not promptly fulfilled, or if the Investment Escrow Agent renders
any service not provided for in this Agreement, or if the parties request a
substantial modification of its terms, or if any controversy arises, or if the
Investment Escrow Agent is made a party to, or intervenes in, any litigation
pertaining to the Investment Escrow Fund or its subject matter, the Investment
Escrow Agent shall be reasonably compensated for such extraordinary services and
reimbursed for all costs, attorney's fees, and expenses occasioned by such
default, delay, controversy or litigation.

          (j)  Investment Escrow Agent's Duties.
               --------------------------------

               (i)   The Investment Escrow Agent shall be obligated only for the
performance of such duties as are specifically set forth herein, and as set
forth in any additional written escrow instructions consistent with this
Agreement which the Investment Escrow Agent may receive after the date of this
Agreement which are signed by an officer of Parent and the Stockholder
Representative, and may rely and shall be protected in relying or refraining
from acting on any instrument reasonably believed to be genuine and to have been
signed or presented by the proper party or parties. The Investment Escrow Agent
shall not be liable for any act done or omitted hereunder as Investment Escrow
Agent while acting in good faith and in the exercise of reasonable judgment, and
any act done or omitted pursuant to the advice of counsel shall be conclusive
evidence of such good faith.

               (ii)  The Investment Escrow Agent is hereby expressly authorized
to comply with and obey orders, judgments or decrees of any court of law,
notwithstanding any notices, warnings or other communications from any party or
any other person to the contrary. In case the Investment Escrow Agent obeys or
complies with any such order, judgment or decree of any court, the Investment
Escrow Agent shall not be liable to any of the parties hereto or to any other
person by reason of such compliance, notwithstanding any such order, judgment or
decree being subsequently reversed, modified, annulled, set aside, vacated or
found to have been entered without jurisdiction.

               (iii) The Investment Escrow Agent shall not be liable in any
respect on account of the identity, authority or rights of the parties executing
or delivering or purporting to execute or deliver this Agreement or any
documents or papers deposited or called for hereunder.

expiration of any rights under any statute of limitations with respect to this
Agreement or any documents deposited with the Investment Escrow Agent.

expenses, except for gross negligence or willful misconduct on the part of the
Investment Escrow Agent. The Investment Escrow Agent shall not incur any such
liability for (A) any act or failure to act made or omitted in good faith, or
(B) any action taken or omitted in reliance upon any instrument, including any

<PAGE>

affidavit provided for in this Agreement that the Investment Escrow Agent shall
in good faith believe to be genuine, nor will the Investment Escrow Agent be
liable or responsible for forgeries, fraud, impersonations, or determining the
scope of any representative authority. In addition, the Investment Escrow Agent
may consult with the legal counsel in connection with Investment Escrow Agent's
duties under this Agreement and shall be fully protected in any act taken,
suffered, or permitted by him/her in good faith in accordance with the advice of
counsel. The Investment Escrow Agent is not responsible for determining and
verifying the authority of any person acting or purporting to act on behalf of
any party to this Agreement.

               (vi)   If any controversy arises between the parties to this
Agreement, or with any other party, concerning the subject matter of this
Agreement, its terms or conditions, the Investment Escrow Agent will not be
required to determine the controversy or to take any action regarding it. The
Investment Escrow Agent may hold all documents and funds of the Parent and may
wait for settlement of any such controversy by final appropriate legal
proceedings or other means as, in the Investment Escrow Agent's discretion, the
Investment Escrow Agent may be required, despite what may be set forth elsewhere
in this Agreement. In such event, the Investment Escrow Agent will not be liable
for damage. Furthermore, the Investment Escrow Agent may at its option, file an
action of interpleader requiring the parties to answer and litigate any claims
and rights among themselves. The Investment Escrow Agent is authorized to
deposit with the clerk of the court all documents and funds of the Parent held
in escrow, except all cost, expenses, charges and reasonable attorney fees
incurred by the Investment Escrow Agent due to the interpleader action and which
the parties jointly and severally agree to pay. Upon such action, the Investment
Escrow Agent shall be fully released and discharged of and from all obligations
and liability imposed by the terms of this Agreement.

               (vii)  The parties and their respective successors and assigns
agree jointly and severally to indemnify and hold Investment Escrow Agent
harmless against any and all losses, claims, damages, liabilities, and expenses,
including reasonable costs of investigation, counsel fees, and disbursements
that may be imposed on Investment Escrow Agent or incurred by Escrow Agent in
connection with the performance of its duties under this Agreement, including
but not limited to any litigation arising from this Agreement or involving its
subject matter, other than arising out of its negligence or willful misconduct.

               (viii) The Investment Escrow Agent may resign at any time upon
giving at least 30 days written notice to the parties; provided, however, that
no such resignation shall become effective until the appointment of a successor
escrow agent which shall be accomplished as follows: Parent and the Stockholder
Representative shall use their commercially reasonable efforts to mutually agree
on a successor escrow agent within 30 days after receiving such notice. If the
parties fail to agree upon a successor escrow agent within such time, the
Investment Escrow Agent shall have the right to appoint a successor escrow agent
authorized to do business in the State of California. The successor escrow agent
shall execute and deliver an instrument accepting such appointment and it shall,
without further acts, be vested with all the estates, properties, rights,
powers, and duties of the predecessor escrow agent as if originally named as
escrow agent. The

                                     -64-
<PAGE>

former Investment Escrow Agent thereupon shall be discharged from any further
duties and liability under this Agreement.

           [SIGNATURE PAGE TO AGREEMENT AND PLAN OF REORGANIZATION]
<PAGE>

                                Amendment No. 1

     This Amendment No. 1 (the "Amendment") is entered into as of this 19/th/
day of December 2000.  The Amendment is to that certain Agreement and Plan of
Reorganization, dated as of October 5, 2000, by and among Centillium
Communications, Inc., Eugene Acquisition Corp., vEngines, Inc. and the Principal
Stockholders (the "Agreement").  Capitalized terms used in this Amendment
without definition have the same meanings specified in the Agreement, unless the
context requires otherwise, and section references used in this Amendment refer
to Sections of the Agreement.

                                  Background

     A.  Section 8.1(e) of the Agreement provides Centillium the right to
terminate the Agreement, by notice to vEngines at a prescribed time, if the
average of the closing prices of the Parent Common Stock on the Nasdaq National
Market have been below $46.00 per share for a specified period.  The termination
right is subject to a right of vEngines to require Centillium to proceed with
the Closing (subject to other closing conditions set forth in the Agreement),
upon providing written notice of vEngines' intent to proceed with the Closing
upon the understanding that the Transaction Stock Price will be set at $51.11,
notwithstanding any calculation to the contrary under Section 1.6(c)(iv).

     B.  The parties desire to amend the Agreement to provide that the
Transaction Stock Price will be set at $51.11 and that the termination right of
Centillium set forth in Section 8.1(e) is deleted and is null and void.

     Therefore, the parties agree to amend the Agreement as follows:

     1.   Section 1.6(c)(iii) is amended and restated to read in its entirety as
follows: ""The Transaction Stock Price" is $51.11."

     2.   Section 1.6(c)(iv) and (v) are deleted in their entirety.

     3.   Parent's termination right under Section 8.1(e) is eliminated and is
          null and void.

     4.   Except as explicitly amended by this Agreement, all other terms and
conditions of the Agreement remain in full force and effect.  This Amendment may

                                      -2-
<PAGE>

be executed in counterparts, each of which shall be deemed an original and all
of which shall constitute one instrument.

       In Witness Whereof, the parties execute this Amendment as of the date
first written above.
