               ----------------------
any of its Common Stock for its own account under the Act for a public offering
for cash (other than a registration relating to a Rule 145 transaction or
employee benefit plans or any other registration which is not appropriate for
the registration of Shares), the Company shall give the Purchaser written notice
of its intent to do so. Upon the written request of the Purchaser given within
15 days after receipt of such notice, the Company will use its best efforts to
cause to be included in such registration all of the Shares which the Purchaser
requests to be registered.

          6.2  Expenses. All expenses incurred in connection with any
               --------
registrations under Section 6.1 (excluding underwriting commissions and

               -------------------------
involving an underwriting of shares being issued by the Company, the Company
shall not be required under Section 6.1 to include any of the Shares unless the
Purchasers accept and agree to the terms of the underwriters selected by the
Company. If the total number of shares of the Company's stock which the
Purchaser and any other persons entitled to include shares of stock in a Company
registration (the "Other Participants") request to be included in any offering
involving an underwriting

                                       11


of shares being issued by the Company (the "Requested Shares") exceeds the
number which the underwriters reasonably believe is compatible with the success
of the offering, then the Company shall only be required to include in the
offering so many Requested Shares as the underwriters believe will not
jeopardize the success of the offering (the Requested Shares to be included
shall be apportioned among the Purchasers and the Other Participants pro rata
according to the number of shares owned by each Purchaser or Other Participant
indicating a desire to participate in such offering); provided, however, that
with respect any offering other than the Company's initial public offering, that
notwithstanding the underwriter's discretion set forth above, a minimum of

               ---------------------------
Company with such information as the Company may request in writing and as shall
be required in connection with any registration under this Article 6 and shall
agree to indemnify the Company and the underwriters of such offering against any
claim or loss resulting from the inaccuracy of such information provided, and on
the condition, that the Company shall agree to provide Purchaser with
indemnification for all other information contained in the registration
statement relating to such registration on usual and customary terms for
offerings of such nature.

          6.5  Definitions. For purposes of this Article 6 the following

a Purchaser to whom the Shares may be subsequently transferred; provided that
the transferor shall specifically transfer its rights under this Article 6 to
such transferee and that such transferee holds more than 250,000 Shares.

          (b)  "Shares" shall mean and include any shares of Common Stock issued
or issuable upon conversion of the Series A Preferred Stock sold in accordance
with this Agreement or any

                                       12


shares of Common Stock issued in respect of such Shares pursuant to any stock
split, dividend, recapitalization and the like.

SECTION 7. RIGHT OF FIRST REFUSAL

          7.1  The Right. The Company will notify the Purchasers and the Founder
               ---------
of any intended offering of New Securities (as defined below) to be undertaken
by the Company after the date of this Agreement and prior to termination of the
right provided herein pursuant to Section 7.3 below. The Purchasers and the
Founder shall have the right of first refusal to participate pro rata in such
offering of New Securities based upon their then existing ownership percentage
in the Company.

          7.2  Notice. The Company shall give to the Purchasers and the Founder
               ------
written notice of the proposed offer to sell and issue any of the New
Securities, which written notice shall contain the terms of such proposed sale
in reasonable detail and shall be delivered to the Purchasers and the Founder at
least thirty (30) days prior to the date such securities are proposed to be sold
and issued to any third party. The Purchasers and the Founder shall have the
right to exercise the right of first refusal granted them pursuant to Section
7.1 above by giving written notice thereof to the Company within fifteen (15)
days after receipt of the Company's notice, specifying the amount of securities
which such person desires to purchase. Failure to so notify the Company within
such period shall be deemed an election not to participate.

          7.3  Termination. The rights granted by this Section 7 shall terminate
               -----------
upon either of the following:

          (a) as to each Purchaser or the Founder, the failure of such person to
exercise its rights under this Article 7 in full with respect to a prior
offering of New Securities; or

          (b) the effectiveness of (and shall not apply to the shares subject
to) a registration statement under the Securities Act on Form S-1, S-2, S-3, SB-
1 or SB-2 (or similar form containing substantially the same information)
covering a firm commitment underwriting of the Company's securities; or

          (c) the closing of a transaction by which the Company is merged into
or acquired by another corporation and in which the shareholders of the Company
hold less than 50% of the voting power of the surviving corporation (and shall
not apply to such transaction).

                                       13


          7.4  Definitions. For purposes of this Article 7, the following shall

rights, options, warrants or other debt, equity or hybrid securities
exchangeable for or convertible into shares of Common Stock which the Company
intends to offer, sell or issue after the date of this Agreement except for such
securities which are (i) exchanged for the securities of another corporation as
a result of a statutory merger or consolidation; (ii) issued to another
corporation in exchange for all or substantially all of the assets of such other
corporation; or (iii) shares of Common Stock (or securities convertible into or
rights to acquire shares of Common Stock) issued to fulfill any obligation of
the Company under any existing or future stock option, bonus or other employee
or consultant incentive arrangement or plan for the benefit of the employees,
consultants or directors of the Company.

          (b) For purposes of determining the Founder's "percentage interest" in
the Company, the Founder's holdings of shares of Series A Preferred Stock,
Common Stock and vested options to purchase Common Stock, if any, shall be
aggregated.

          7.5  Transferability. A Purchaser's right to purchase New Securities

under the terms of this Article 7 shall be nontransferable.

                                      OF

                         ARTICLES OF INCORPORATION OF

                              ARTEST CORPORATION

          Jen Kao and Chia Yin Kao certify that:

          1.  They are the President and Secretary, respectively, of Artest
Corporation, a California corporation.

          2.  Article IV of the Articles of Incorporation of this corporation is
amended and restated to read in its entirety, as follows:


                                  "Article IV

          This corporation is authorized to issue two classes of shares
designated "Series A Preferred Stock" and "Common Stock," respectively. The
total number of shares which this corporation shall have the authority to issue
is Thirty Eight Million (38,000,000). The number of shares of Series A
Preferred Stock authorized to be issued is Fourteen Million (14,000,000), and
the number of shares of Common Stock authorized to be issued is Twenty Four
Million (24,000,000).

          A statement of the rights, preferences, privileges and restrictions
granted to or imposed on the Series A Preferred Stock and the holders thereof is
as follows:

          1.  Dividends.
              ---------

          (a) Preference. The holders of outstanding Series A Preferred Stock
              ----------
shall be entitled to receive, when and as declared by the Board of Directors,
out of any assets at the time legally available therefor, dividends in cash at
the rate of $0.08 per share per annum before any dividend is paid on Common
Stock. The right to such dividends on shares of Series A Preferred Stock shall
not be cumulative. Such dividend is payable when and as the Board of Directors
may from time to time determine. Dividends or distributions (other than
dividends payable solely in shares of Common Stock) may be declared and paid
upon shares of Common Stock only if dividends shall have been paid on or
declared and set apart upon all shares of Series A Preferred Stock.

                                       1


          (b) Non-Cash Dividends. In the event this corporation shall declare a
              ------------------
distribution payable in securities of other persons, evidences of indebtedness
issued by this corporation or other persons, assets (excluding cash dividends)
or options or rights to purchase any such securities or evidences of
indebtedness, then, in each such case the holders of the Series A Preferred
Stock shall be entitled to a proportionate share of any such distribution as
though the holders of the Series A Preferred Stock were the holders of the
number of shares of Common Stock of the corporation into which their respective
shares of Series A Preferred Stock are convertible as of the record date fixed
for the determination of the holders of Common Stock of the corporation entitled
to receive such distribution.

          (c) Consent to Certain Repurchases. As authorized by Section 402.5(c)
              ------------------------------
of the California Corporations Code, Sections 502, 503 and 506 of the California
Corporations Code shall not apply with respect to distributions (as defined in
Section 166 of the California Corporations Code) made by the Company in
connection with the repurchase of shares of Common Stock issued to or held by
employees, consultants, officers and directors upon termination of their
employment or services pursuant to agreements providing for the right of said
repurchase.

          2.  Liquidation Distributions.
              -------------------------

          (a) Series A Preference. In the event of any liquidation, dissolution
              -------------------
or winding up of the corporation, either voluntary or involuntary, the holders
of the Series A Preferred Stock shall be entitled to receive, prior and in
preference to any distribution of any of the assets or surplus funds of the
corporation to the holders of the Common Stock by reason of their ownership
thereof, the amount of One dollar ($ 1.00) per share. If upon the occurrence of
such event the assets and funds thus distributed among the holders of the Series
A Preferred Stock shall be insufficient to permit the payment to such holders of
the full preferential amount, then the entire assets and funds of the
corporation legally available for distribution shall be distributed ratably
among the holders of the Series A Preferred Stock.

          (b) Distributions on Common. After payment has been made to the
              -----------------------
holders of the Series A Preferred Stock of the full amounts to which they shall
be entitled as set forth in subsection (a) above, the remaining assets of the
corporation available for distribution to shareholders shall be distributed
among the holders of Common Stock pro rata based upon the number of shares of
Common Stock held by each such holder.

                                       2


          (c) Reorganization. For purposes of this Section 2, a liquidation,
              --------------
dissolution or winding up of the Company shall be deemed to be occasioned by, or
to include, (A) the acquisition of the Company by another entity by means of any
transaction or series of related transactions (including, without limitation,
any reorganization, merger or consolidation but excluding any merger effected
exclusively for the purpose of changing the domicile of the Company) that
results in the transfer of fifty percent (50%) or more of the outstanding voting
power of the Company; or (B) a sale of all or substantially all of the assets of
the Company.

          3.  Conversion. The holders of the Series A Preferred Stock shall have
              ----------
conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.
               ----------------

               (i)   Each share of Series A Preferred Stock shall be
convertible, at the option of the holder thereof, at the office of the
corporation or any transfer agent for the Series A Preferred Stock, into Common
Stock. The initial rate upon which the Series A Preferred Stock shall be
convertible into shares of Common Stock shall be one share of Common Stock for
each share of Series A Preferred Stock converted, subject to adjustment as
provided herein. (The number of shares of Common Stock into which each share of
Series A Preferred Stock may be converted is hereinafter referred to as the
"Conversion Rate".)

               (ii)  Each share of Series A Preferred Stock shall automatically
be converted into shares of Common Stock at the then effective Conversion Rate
immediately upon either (A) the consummation of the corporation's sale of Common
Stock pursuant to a registration statement under the Securities Act of 1933, as
amended, pursuant to an underwritten firm commitment public offering or (B) upon
the written consent to such conversion of holders of more than 50% of the
outstanding shares of Series A Preferred Stock, whichever first shall occur.

               (iii) No fractional shares of Common Stock shall be issued upon
conversion of any Series A Preferred Stock and if any shares of Series A
Preferred Stock surrendered for conversion would otherwise result in a
fractional share of Common Stock, such fractional share shall be redeemed for
the then fair market value thereof as reasonably determined by the corporation's
Board of Directors, payable as promptly as possible whenever funds are legally
available therefor. If more than one share of Series A Preferred Stock is
surrendered for

                                       3


conversion at any one time by the same holder, the number of full shares of
Common Stock to be issued upon conversion shall be computed on the basis of the
aggregate number of shares of Series A Preferred Stock so surrendered.

          (b) Mechanics of Conversion. Before any holder of Series A Preferred
              -----------------------
Stock shall be entitled to convert the same into shares of Common Stock, such
holder shall surrender the certificate or certificates therefor, duly endorsed,
at the office of the corporation or of any transfer agent for the Series A
Preferred Stock, and shall give written notice to the corporation at such office
that such holder elects to convert the same and shall state therein the name or
names in which such holder wishes the certificate or certificates for shares of
Common Stock to be issued. The corporation shall, as soon as practicable
thereafter, issue and deliver at such office to such holder of Series A
Preferred Stock, or to such holder's nominee or nominees, a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled as aforesaid. Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
shares of Series A Preferred Stock to be converted, and the person or persons
entitled to receive the shares of Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder or holders of such shares
of Common Stock on such date.

          (c) Adjustment of Conversion Rate for Combinations or Consolidations
              ----------------------------------------------------------------
of Common Stock. In the event the corporation at any time or from time to time
- ---------------
effects a subdivision or combination of its outstanding Common Stock into a
greater or lesser number of shares without a proportionate and corresponding
subdivision or combination of the Series A Preferred Stock, then and in each
such event the Conversion Rate for the Series A Preferred Stock shall be
increased or decreased proportionately.

          (d) No Impairment. The corporation will not, by amendment of its
              -------------
Articles of Incorporation or through any reorganization, re-capitalization,
transfer of assets, merger, dissolution, issue or sale of securities or any
other voluntary action, avoid or seek to avoid the observance or performance of
any of the terms to be observed or performed hereunder by the corporation, but
will at all times in good faith assist in the carrying out of all the provisions
of this section 3 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of the
Series A Preferred Stock against impairment.

                                       4


          4.   Voting Rights.
               -------------

          (a)  General. Each holder of shares of the Series A Preferred Stock
               -------
shall be entitled to the number of votes equal to the number of shares of Common
Stock into which such shares of Series A Preferred Stock could be converted on
the record date for the vote or consent of shareholders and shall have voting
rights and powers equal to the voting rights and powers of the Common Stock. The
holder of each share of the Series A Preferred Stock shall be entitled to notice
of any shareholders' meeting in accordance with the Bylaws of the corporation
and shall vote with holders of the Common Stock upon the election of directors
and upon any other matter submitted to a vote of shareholders, except those
matters required by law to be submitted to a class vote. Fractional votes by the
holders of Series A Preferred Stock shall not, however, be permitted and any
fractional voting rights resulting from the above formula (after aggregating all
shares into which shares of Series A Preferred Stock held by each holder could
be converted) shall be rounded to the nearest whole number.

          (b)  Special Voting Rights. In addition to any other rights provided
               ---------------------
by law, so long as shares of Series A Preferred Stock are outstanding, the
corporation shall not without first obtaining the affirmative vote or written
consent of the holders of not less than a majority of the then outstanding
shares of the Series A Preferred Stock:

               (i)   sell, convey, or otherwise dispose of or encumber all or
substantially all of its property or business or merge into or consolidate with
any other corporation (other than a wholly owned subsidiary corporation) or
effect any transaction or series of transaction in which 50% of the voting power
of the corporation is disposed of;

               (ii)  amend or repeal any provision of, or add any provision to,
this Corporation's Articles of Incorporation if such action would alter or
change the preferences, rights, privileges or powers of, or the restrictions
provided for the benefit of, the Series A Preferred Stock;

               (iii) amend or repeal any provision of, or add any provision to,
this Corporation's Articles of Incorporation if such action would increase the
number of authorized shares of Series A Preferred Stock or the number of
authorized shares of Common Stock;

               (iv)  authorize or issue shares of any class of stock not
authorized herein having any preference or priority as

                                       5


to dividends or assets superior to or on a parity with any such preference or
priority of the Series A Preferred Stock or authorize or issue any bonds,
debentures, notes or other obligations convertible into or exchangeable for, or
having option rights to purchase, any shares of stock of this Corporation other
than Common Stock; or

               (v)  reclassify any shares of Common Stock and any other shares
of this Corporation other than the Series A Preferred Stock into shares having
any preference or priority as to dividends or assets superior to or on a parity
with any such preference or priority of the Series A Preferred Stock."

          3.   The foregoing Amendment of Articles of Incorporation has been
duly approved by the Board of Directors of this Corporation.

          4.   The foregoing Amendment of the Articles of Incorporation has been
approved by the required vote of shareholders in accordance with Sections 902
and 903 of the Corporations Code. The total number of outstanding shares of
Common Stock of the corporation is 5,240,000. The number of shares voting in
favor of the amendment equaled or exceeded the vote required. The percentage
vote required was more than 50% of the outstanding shares of Common Stock.
