This AGREEMENT AND PLAN OF MERGER (the "AGREEMENT") is made and entered
into as of December 14, 1999 by and between UTStarcom, Inc., a Delaware

RECITALS

A. This Agreement contemplates a tax-free merger of the Company with
and into Buyer in a reorganization pursuant to Section 368(a)(1)(A) of the

B. The Boards of Directors of each of Buyer and Company believe it is
in the best interests of each company and their respective stockholders that the

NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
the parties agree as follows:

Effective Time (as defined in Section 1.4(a) below). The Buyer shall be the
corporation surviving the Merger.

1.2 THE CLOSING. The closing of the transactions contemplated by this
Agreement (the "CLOSING") shall take place at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇
▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇, Professional Corporation, in Palo Alto, California,
commencing at 10:00 a.m. local time on the second business day following the
satisfaction or waiver of all conditions to the obligations of the parties to
consummate the transactions contemplated hereby (other than conditions with
respect to actions the respective parties will take at the Closing itself) or
such other date and time as the parties may mutually determine (the "CLOSING
DATE").

1.3 ACTIONS AT THE CLOSING. At the Closing: (i) the Company will
deliver to the Buyer the various certificates, instruments, and documents as
required by Section 5.3 below; (ii) the Buyer will deliver to the Company the
various certificates, instruments, and documents as required by Section 5.2
below; (iii) the Buyer and the Company will file an agreement of merger with the
Secretary of State of the State of California and the Secretary of State of the
State of Delaware; and (iv) the Buyer will deliver to the stockholders of the
Company (the "STOCKHOLDERS") in the manner provided in

Section 1.5 below, the certificates evidencing the Buyer Shares (as defined
below) to be issued in the Merger.

1.4 EFFECT OF MERGER

(a) GENERAL. The Merger shall become effective at the time
(the "EFFECTIVE TIME") the Buyer and the Company file the agreement of merger
with the Secretary of State of the State of California and the Secretary of
State of the State of Delaware. The Merger shall have the effect set forth in
the Delaware General Corporation Law and the applicable laws of the State of
California. Without limiting the generality of the foregoing, and subject
thereto, at the Effective Time, all the property, rights, privileges, powers and
franchises of the Company shall vest in Buyer, and all debts, liabilities and
duties of the Company shall become the debts, liabilities and duties of Buyer.
The Buyer may, at any time after the Effective Time, take any action (including
executing and delivering any document) in the name and on behalf of the Company
in order to carry out and effectuate the transactions contemplated by this
Agreement.

(b) CERTIFICATE OF INCORPORATION. The Certificate of
Incorporation of the Buyer in effect at and as of the Effective Time will remain
the Certificate of Incorporation of the Buyer without any modification or
amendment resulting from the Merger.

(c) BYLAWS. The Bylaws of the Buyer in effect at and as of the
Effective Time will remain the Bylaws of the Buyer without any modification or
amendment resulting from the Merger.

(d) DIRECTORS AND OFFICERS. The directors and officers of the
Buyer in office at and as of the Effective Time will remain the directors and
officers of the Buyer (retaining their respective positions and terms of
office).

(e) CONVERSION OF COMPANY SHARES. At and as of the Effective
Time:

(i) Each outstanding share of Common Stock of the
Company ("COMPANY COMMON STOCKS") shall be cancelled and extinguished and be
converted automatically into the right to receive 0.4498070 shares of Series G
Preferred Stock, $0.0025 per value, of Buyer ("BUYER SHARES") (the ratio of
0.4498070 Buyer Shares to one (1) Company Common Stock is referred to herein as
the "COMMON STOCK CONVERSION RATIO").

(ii) Each outstanding share of Series B Preferred Stock
of the Company ("COMPANY SERIES B SHARES") shall be cancelled and extinguished
and be converted automatically into the right to receive 0.9335977 Buyer Shares
(the ratio of 0.9335977 Buyer Shares to one (1) Company Series B Share is
referred to herein as the "SERIES B CONVERSION RATIO")

The Common Stock Conversion Ratio and the Series B Conversion Ratio shall
be subject to equitable adjustment in the event of any stock split, stock
dividend, reverse stock split, or other change in the capital stock of the Buyer
prior to the Effective Time. The number of Buyer Shares

-2-

which shall be delivered to each Stockholder at the Closing is as set forth on
SCHEDULE 2.2(a) attached hereto. The aggregate number of Buyer Shares issuable
to the holders of Company Common Stock and Company Series B Shares
(collectively, the "COMPANY SHARES") pursuant to this Section 1.4(e) is
hereinafter referred to as the "MERGER CONSIDERATION". No Company Share shall
be deemed to be outstanding or to have any rights other than those set forth
above in this Section 1.4(e) after the Effective Time.

(f) NO FRACTIONAL SHARES. No fractional of a share of Buyer
Shares will be issued, but in lieu thereof, each holder of shares of Company
Capital Stock who would otherwise be entitled to a fraction of a share of Buyer
Shares (after aggregating all fractional shares of Buyer Common Stock to be
received by such holder) shall be entitled to receive from Buyer an amount of
cash (rounded to the nearest whole cent) equal to the product of (i) such
fraction, multiplied by (ii) $16.2605.

(g) COMPANY STOCK OPTIONS. At the Effective Time, all options
to purchase Company Common Stock then outstanding under the Company's 1997 Stock
Plan (the "OPTION PLAN") or otherwise shall be assumed by Buyer in accordance
with provisions described below:

(i) At the Effective Time, each outstanding option to
purchase shares of Company Common Stock (each a "COMPANY OPTION") under the
Option Plan or otherwise, whether vested or unvested, shall be, in connection
with the Merger, assumed by Buyer. Each Company Option so assumed by Buyer
under this Agreement shall continue to have, and be subject to, the same terms
and conditions set forth in the Option Plan and/or as provided in the respective
option agreements governing such Company Option immediately prior to the
Effective Time, except that such Company Option shall be exercisable for that
number of whole shares of the Buyer's Common Stock equal to the product of the
number of shares of Company Common Stock that were issuable upon exercise of
such Company Option immediately prior to the Effective Time multiplied by
0.4498070, rounded down (in the case of Company Options granted under the Option
Plan) to the nearest whole number of shares of the Buyer's Common Stock.

(ii) It is the intention of the parties that the Company
Options assumed by Buyer qualify following the Effective Time as incentive
stock options as defined in Section 422 of the Code to the extent the Company
Options qualified as incentive stock options immediately prior to the Effective
Time.

(h) BUYER SHARES. Each Buyer Share issued and outstanding at
and as of the Effective Time will remain issued and outstanding.

1.5 PROCEDURE FOR ISSUANCE OF BUYER SHARES.

(a) Promptly after the Effective Time, Buyer shall make
available to the Stockholders of the Company the Buyer Shares issuable to such
Stockholders pursuant to Section 1.4(e) in exchange for all of the outstanding
capital stock of the Company.

-3-

(b) The Buyer will not pay any dividend or make any
distribution on Buyer Shares (with a record date at or after the Effective
Time) to any Stockholder until such Stockholder surrenders for exchange his
certificates which formerly represented Company Shares. The Buyer instead will
hold such dividend in trust for the benefit of such Stockholder pending
surrender and exchange. In no event, however, will any Stockholder be entitled
to any interest or earnings on the dividend or distribution pending receipt.

1.6 CLOSING OF TRANSFER RECORDS. After the close of business on the
Closing Date, transfers of Company Shares outstanding prior to the Effective
Time shall not be made on the stock transfer books of the Company.

1.7 NO FURTHER OWNERSHIP RIGHTS IN COMPANY SHARES. All amounts paid
upon the surrender for exchange of the Company Shares in accordance with the
terms hereof shall be deemed to have been issued in full satisfaction of all
rights pertaining to such Company Shares, and there shall be no further
registration of transfers on the records of the Company of Company Shares which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, certificates are presented to the Buyer for any reason, they
shall be canceled and the Buyer Shares shall be delivered to the person
entitled thereto.

1.8 LOST, STOLEN OR DESTROYED CERTIFICATES. In the event any
certificates evidencing Company Shares shall have been lost, stolen or
destroyed, Buyer shall make payment in exchange for such lost, stolen or
destroyed certificates, upon the making of an affidavit of that fact by the
holder thereof, such amount, if any, as may be required pursuant to Section
1.5; PROVIDED, HOWEVER, that Buyer may, in its sole discretion and as a
condition precedent to the issuance thereof, require the owner of such lost,
stolen or destroyed certificates to deliver an agreement (in form and substance
satisfactory to it) to indemnify Buyer against any claim that may be made
against Buyer with respect to the certificates alleged to have been lost,
stolen or destroyed.

1.9 TAX AND ACCOUNTING TREATMENT. The Merger shall constitute a
tax-free transaction pursuant to Section 368(a)(1)(A) of the Internal Revenue
Code of 1986, as amended (the "Code"), and will be treated as a "purchase" for
financial accounting purposes.

1.10 TAKING OF NECESSARY ACTION; FURTHER ACTION. If, at any time
after the Effective Time, any further action is necessary or desirable to carry
out the purposes of this Agreement and to vest the Buyer with full right, title
and possession to all assets, property, rights, privileges, powers and
franchises of the Company, the officers and directors of the Company and Buyer
are fully authorized in the name of their respective corporations or otherwise
to take, and will take, all such lawful and necessary and/or desirable action.

Stockholders. The Company's Board of Directors and the Stockholders have
approved the Merger and this Agreement as required by applicable law. This
Agreement has been duly executed and delivered by the Company and constitutes

insolvency and the relief of debtors and rules of law governing specific
performance, injunctive relief or other equitable remedies. Except as set
forth on SCHEDULE 2.4, subject only to the approval of the Merger and this
Agreement by the Company's Stockholders, the execution and delivery of this
Agreement by the Company does not, and, as of the Effective Time, the
consummation of the transactions contemplated hereby will not, conflict with,
or result in any violation of, or default under (with or without notice or
lapse of time, or both), or give rise to a right of termination, cancellation
or acceleration of any obligation or loss of any benefit that would have a
Material Adverse Effect under (any such event, a "Conflict") (i) any provision
of the Certificate of Incorporation or Bylaws of the Company or (ii) any
mortgage, indenture, lease, contract or other agreement or instrument, permit,
concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to the Company or its properties or
assets. No consent, waiver, approval, order or authorization of, or
registration, declaration or filing with, any court, administrative agency or
commission or other federal, state, county, local or foreign governmental
authority, instrumentality, agency or Commission ("Governmental Entity") or any
third party (so as not to trigger any Conflict), is required by or with respect
to the Company in connection with the execution and delivery of this Agreement
or the consummation of the transactions contemplated hereby, except for the
filing of an agreement of merger with the California Secretary of State and the
Delaware Secretary of State and such other consents, waivers, authorizations,
filings, approvals and registrations which are set forth on SCHEDULE 2.4.

2.5 COMPANY FINANCIAL STATEMENTS. The Company has provided Buyer
with the Company's unaudited balance sheet as of September 30, 1999 and the
related unaudited profit and

-6-

loss statement for the twelve-month period then ended (collectively, the
"COMPANY FINANCIALS"). The Company Financials are true and correct in all
material respects and are consistent throughout the periods indicated and
consistent with each other. The Company Financials present fairly the
financial condition and operating results of the Company as of the dates and
during the periods indicated therein, subject to normal year-end adjustments,
which will not be material in amount or significance in the aggregate.

2.6 RESTRICTIONS ON BUSINESS ACTIVITIES. Other than the restrictions
contained in the agreements listed in the Disclosure Schedule, there is no
agreement (noncompete or otherwise), commitment, judgment, injunction, order or
decree to which the Company or any of the Stockholders are a party or otherwise
binding upon the Company or any of the Stockholders which has or reasonably
could be expected to have the effect of materially prohibiting or impairing any
business practice of the Company, any acquisition of property (tangible or
intangible) by the Company, the conduct of business by the Company or the
operation of the business of the Company by Buyer following the Effective Time.

2.7 TITLE OF PROPERTIES; ABSENCE OF LIENS AND ENCUMBRANCES; CONDITION
OF EQUIPMENT.

(a) The Company has good and valid title to, or, in the case
of leased properties and assets, valid leasehold interests in, all of its
tangible properties and assets, real, personal and mixed, used or held for use
in its business, free and clear of any Liens (as defined in Section 2.8(vii)),
except as reflected in the Company Financials or in the Disclosure Schedule and
except for liens for Taxes not yet due and payable and such imperfections of
title and encumbrances, if any, which are not material in character, amount or
extent, and which do not materially detract from the value, or materially
interfere with the present use, of the property subject thereto or affected
thereby.

(b) Except as described in the Disclosure Schedule, the
equipment (the "EQUIPMENT") owned or leased by the Company is, taken as a
whole, (i) adequate for the conduct of the business of the Company as currently
conducted and (ii) in good operating condition, regularly and properly
maintained, subject to normal wear and tear.

2.8 INTELLECTUAL PROPERTY. The Company has sufficient title and
ownership of patents, copyrights, trademarks, trade secrets, and all other
proprietary rights needed to conduct its business as proposed to be conducted.

There are no pending infringement claims regarding any third
party's patents, copyrights, trademarks, trade secrets or proprietary rights
and processes against the Company nor, to the best of the Company's knowledge,
is there any threat thereof or basis therefor. To the best of the Company's
knowledge, the Company is not infringing upon or otherwise acting adversely to,
and will not, by conducting its business as presently conducted, infringe upon
or otherwise act adversely to, the right or claimed right of any other person
with respect to any of the foregoing. The Company is not aware of any
violation by a third party of any of its patents, copyrights, trademarks, trade

-7-

secrets or other proprietary rights. The Company has taken reasonable security
measures to protect the secrecy, confidentiality and value of its proprietary
information.

The Company is not aware that any of its employees is obligated
under any contract (including licenses, covenants or commitments of any nature)
or other agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of the employee's best
efforts to promote the interests of the Company or that would conflict with the
Company's business as proposed to be conducted. Neither the execution nor
delivery of this Agreement, nor the carrying on of the Company's business by
the employees of the Company, will, to the Company's knowledge, conflict with
or result in a breach of the terms, conditions or provisions of, or constitute
a default under, any contract, covenant or instrument under which any of such
employees is now obligated. The Company does not believe it is or will be
necessary to utilize any inventions of any of its employees (or people it
currently intends to hire) made prior to their employment by the Company.

2.9 INTERESTED PARTY TRANSACTIONS. Except as set forth on SCHEDULE
2.9, no officer, director or Stockholder of the Company (nor any ancestor,
sibling, descendant or spouse of any of such persons, or any trust, partnership
or corporation in which any of such persons has an interest), has, directly or
indirectly, (i) an interest in any entity which furnished or sold, or furnishes
or sells, services or products that the Company furnishes or sells, or proposes
to furnish or sell, or (ii) an interest in any entity that purchases from or
sells or furnishes to, the Company, any goods or services or (iii) a beneficial
interest in any contract or agreement set forth in SCHEDULE 2.9; provided, that
ownership of no more than one percent (1%) of the outstanding voting stock of a
publicly traded corporation shall not be deemed an "interest in any entity" for
purposes of this SECTION 2.9.

2.10 GOVERNMENTAL AUTHORIZATION. SCHEDULE 2.10 accurately lists each
material consent, license, permit, grant or other authorization issued to the
Company by a Governmental Entity (i) pursuant to which the Company currently
operates or holds any interest in any of its properties or (ii) which is
required for the operation of its business or the holding of any such interest
(herein collectively called "COMPANY AUTHORIZATIONS"), which Company
Authorizations are in full force and effect and constitute all Company
Authorizations required to permit the Company to operate or conduct its
business substantially as it is currently and has been conducted or hold any
interest in its properties or assets.
