               ---------
 
               (a)  The holders of shares of Series A Preferred Stock shall be
entitled to receive dividends, out of any assets legally available therefor,
prior and in preference to any declaration or payment of any dividend (payable
other than in shares of Common Stock or other securities and rights convertible
into or entitling the holder thereof to receive, directly or indirectly,
additional shares of Common Stock of this Corporation) on the Common Stock of
this Corporation, cash dividends at the annual rate of $0.48 per share, payable
if when and as declared by the board of directors. Such dividends shall not be
cumulative.
 
               (b)  After dividends on the Series A Preferred Stock shall have
been declared and paid or set apart, if the board of directors shall elect to
declare additional dividends out of funds legally available therefor, such
additional dividends shall be declared in equal amounts per share on all shares
of Series A Preferred Stock and Common Stock.
 
          2.   Liquidation Preference.
               ----------------------
 
               (a)  (i)  For the purposes of this Section 2(a), the following
definitions shall apply:
 
                         (1)  "Common Share Purchase Price" means $3.00 per
share (subject to adjustment for splits, dividends, combinations,
reclassifications, and the like);
 
                         (2)  "Distributable Assets" means the aggregate dollar
value of all assets available for distribution upon a Liquidation;
 
                         (3)  "Distributable Assets per Share" means the number
calculated by dividing the Distributable Assets by the Total Shares;
 
                         (4)  "PCT" means the number calculated by dividing $24
minus Distributable Assets per Share by $8.00;
 
                         (5)  "Series A Purchase Price" means $8.00 per share
(subject to adjustment for splits, dividends, combinations, reclassifications
and the like);
 
                         (6)  "Total Shares" means the sum of the number of
actually issued and outstanding shares of Common Stock and the number of shares
of Common Stock issuable upon the conversion of all actually issued and
outstanding shares of preferred stock including all shares of Series A Preferred
Stock as of the record date fixed by the Board of Directors in connection with
such Liquidation.
 
                                       2.

 
               (ii)   In the event of any voluntary or involuntary liquidation,
dissolution or winding up ("Liquidation") of the Corporation, the holders of
shares of Series A Preferred Stock then outstanding shall be entitled to be
paid, out of the assets of the Corporation available for distribution to its
shareholders, before any payment shall be made in respect of the Corporation's
Common Stock, an amount per share equal to all declared and unpaid dividends
thereon, if any, to the date fixed for distribution, plus a preference amount
determined according to the following table:
 
          Distributable                  Preference per Share of
          Assets per Share               Series A Preferred Stock
          ----------------               ------------------------
 
          Less than $16                  Series A Purchase Price
 
          Greater than or equal
          to $16, but less than
          or equal to $24                PCT x Series A Purchase Price
 
          Greater than $24               $0
 
          If, upon any Liquidation of the Corporation, the assets of the
Corporation available for distribution to its shareholders shall be insufficient
to pay the holders of the Series A Preferred Stock the full amounts to which
they shall be entitled, all assets of the Corporation available for distribution
shall be distributed ratably to the holders of the Series A Preferred Stock.
 
               (iii)  In the event that the quotient obtained by dividing (a)
the difference between (1) the Distributable Assets and (2) the aggregate
preferential amount, if any, due the holders of Series A Preferred Stock as set
forth in Section 2(a)(ii) above (the "Aggregate Series A Preference Amount") by
(b) the number of actually issued and outstanding shares of Common Stock (the
"Total Common Shares") is less than or equal to the Common Share Purchase Price,
after setting apart or paying in full the preferential amounts, if any, due the
holders of Series A Preferred Stock as set forth in Section 2(a)(ii) above, the
remaining assets of the Corporation available for distribution to shareholders,
if any, shall be distributed to the holders of Common Stock, each such actually
issued and outstanding share of Common Stock entitling the holder thereof to
receive an equal portion of such remaining assets.
 
               (iv)   In the event that the quotient obtained by dividing (a)
the difference between (1) the Distributable Assets and (2) the Aggregate Series
A Preference Amount by (b) the Total Common Shares is greater than the Common
Share Purchase Price, after setting apart and paying in full the preferential
amounts, if any, due the holders of Series A Preferred Stock as set forth in
Section 2(a)(ii) above the remaining assets of the Corporation available for
distribution to shareholders, if any, shall be distributed to the holders of
Series A Preferred Stock and Common Stock, with

                                       3.

 
the amount of such distribution for each share of Series A Preferred Stock being
equal to the amount of such distribution for each share of Common Stock (each
such issued and outstanding share of Common Stock entitling the holder thereof
to receive an equal portion of such remaining assets) multiplied by the number
of shares of Common Stock into which such share of Series A Preferred Stock is
convertible as of the date fixed for such distribution, subject to completion of
the following distributions before such participating distribution:

                    (x)  first, each holder of a share of Common Stock shall
have received, pursuant to this Section 2(a)(iv), an amount equal to the Common
Share Purchase Price before any holder of Series A Preferred Stock shall be
entitled to participate in any pro rata distribution pursuant to this Section
2(a)(iv); and
 
                    (y)  second, after such payment has been made pursuant to
subparagraph (iv) (x) immediately above, each holder of Series A Preferred Stock
shall have received, pursuant to this Section 2(a)(iv), an amount equal to the
Common Share Purchase Price before any holder of Common Stock shall be entitled
to participate further in any pro rata distribution pursuant to this Section
2(a)(iv).

               (b)  A consolidation or merger of this Corporation or an
affiliated corporation with or into any other corporation or corporations, a
sale of all or substantially all of the assets of this Corporation in one or
more related transactions, or the effectuation by this Corporation of a
transaction or series of related transactions whereby, in each case, more than
50% of the voting power of this Corporation is disposed of (excluding a
reincorporation merger) (collectively, an "Acquisition Transaction") may, upon
the election of holders of a majority of the outstanding shares of Series A
Preferred Stock in writing to this Corporation, be treated as a Liquidation for
purposes of this Section 2.
 
               (c)  In the event this Corporation shall propose to take any
action of the type described in subsection (a) or (b) of this Section 2, this
Corporation shall, within ten (10) days after the date the board of directors
approves such action or twenty (20) days prior to any shareholders' meeting
called to approve such action, whichever is earlier, give each holder of shares
of the Series A Preferred Stock written notice of the proposed action. Such
written notice shall describe the material terms and conditions of such proposed
action, including a description of the stock, cash and property to be received
by the holders of shares of the Series A Preferred Stock upon consummation of
the proposed action and the proposed date of delivery thereof. If any material
change in the facts set forth in the notice shall occur, this Corporation shall
promptly give written notice to each holder of shares of the Series A Preferred
Stock of such material change.

                                       4.

 
               (d)  This Corporation shall not consummate any proposed action of
the type described in subsection (a) or (b) of this Section 2 before the
expiration of thirty (30) days after the mailing of the initial written notice
or ten (10) days after the mailing of any subsequent written notice, whichever
is later; provided, however, that any such 30-day or 10-day period may be
shortened upon the written consent of the holders of a majority of the
outstanding shares of the Series A Preferred Stock.
 
               (e)  If this Corporation shall propose to take any action of the
type described in subsection (a) or (b) of this Section 2 which will involve the
distribution of assets or properties other than cash, this Corporation shall
promptly engage, at its expense, independent competent appraisers whose findings
must be acceptable to the Series A Director Designee (as defined herein) to
determine the value of the assets or properties to be distributed to the holders
of shares of the Series A Preferred Stock and the Common Stock. This Corporation
shall, upon receipt of such appraiser's valuation, give prompt written notice of
the appraiser's valuation to each holder of shares of the Series A Preferred
Stock.

          3.   Redemption.
               ----------
 
               (a)  (i)    Subject to the terms and conditions of this Section
3, to the extent that any outstanding shares of Series A Preferred Stock have
not been redeemed and that any outstanding shares of Series A Preferred Stock
have not been converted into Common Stock prior to the fifth anniversary of the
date on which this Corporation first issues shares of Series A Preferred Stock
(the "Original Issue Date"), this Corporation shall, solely at the option of the
holders of at least a majority of the shares of Series A Preferred Stock, upon
receiving, at any time prior to the fifth anniversary of the Original Issue
Date, a written request for the redemption of Series A Preferred Stock signed by
holders owning a majority of the then outstanding shares of Series A Preferred
Stock, redeem in cash at the Redemption Price (as defined below) on the fifth
anniversary of the Original Issue Date a number of shares of Series A Preferred
Stock equal to 50% of such shares that are outstanding on such date and on the
sixth anniversary of the Original Issue Date the remaining number of shares of
Series A Preferred Stock that are outstanding on such date, resulting in the
redemption or conversion to Common Stock as provided in Section 5 of all
outstanding shares of Series A Preferred Stock.

                    (ii)   Upon the receipt of a written redemption request
referenced in Section 3(a)(i) above, this Corporation shall give written notice
by mail, postage prepaid, to the holders of the Series A Preferred Stock then
outstanding to be redeemed that all shares of Series A Preferred Stock will be
redeemed on such redemption dates as specified in subsection 3(a) for a cash
price equal to $8.00 per share (adjusted for any dividends, subdivisions,
combinations or reclassifications and the like with respect to such shares) plus
an amount equal to any declared but unpaid dividends on each such share of
Series A Preferred Stock (the "Redemption Price"). The notice

                                       5.

 
shall further call upon each such holder to surrender to this Corporation on or
before such redemption date at the place designated in the notice such holder's
certificate or certificates representing such holder's pro rata portion of the
shares to be redeemed and shall state that, in lieu of redemption, a holder may,
prior to either such redemption date, convert its Series A Preferred Stock into
Common Stock in accordance with Section 5 below.  On or after such redemption
date, each holder of shares of Series A Preferred Stock called for redemption
shall surrender the certificate evidencing such shares to this Corporation,
except that such number of shares shall be reduced by the number of shares which
have been converted into Common Stock between the date of the written redemption
request and such redemption date, at the place designated in such notice and
shall thereupon be entitled to receive payment of the Redemption Price.

               (b)  From and after the relevant redemption date, unless there
shall have been a default in payment of the appropriate redemption price, all
rights of the holders with respect to such redeemed shares of Series A Preferred
Stock (except the right to receive on the Closing Date the Redemption Price with
interest upon surrender of the stock certificates) shall cease and such shares
shall not thereafter be transferred on the books of this Corporation or be
deemed to be outstanding for any purpose whatsoever.
 
               (c)  If the funds of this Corporation legally available for
redemption of shares of Series A Preferred Stock on the relevant redemption date
are insufficient to redeem the total number of shares of Series A Preferred
Stock to be redeemed on such date, this Corporation shall use those funds which
are legally available to redeem in cash the maximum possible number of such
shares ratably among the holders of such shares to be redeemed. The shares of
Series A Preferred Stock not redeemed shall remain outstanding and shall be
entitled to all the rights and preferences provided herein. At any time
thereafter when additional funds of this Corporation are legally available for
the redemption of shares of Series A Preferred Stock, such funds will
immediately be used to redeem the balance of the shares which this Corporation
has become obligated to redeem on the relevant redemption date but which it has
not redeemed.
 
               (d)  Although this Corporation and the holders of the Series A
Preferred Stock expect this Corporation will have sufficient funds to effect
each such redemption, if this Corporation lacks legally sufficient funds and
assets at the time of request to effect the timely redemption of the shares of
Series A Preferred Stock that are subject to redemption, then this Corporation
shall pay, on each six-month anniversary following the first applicable
redemption date and each subsequent six-month anniversary date until the overdue
redemption payment is made in full, a dividend on the aggregate overdue
redemption payment in an amount equal to the product of the aggregate overdue
redemption payment from time to time outstanding during the six months preceding
such six-month anniversary and the greater of 12% or 5% over the "reference

                                       6.

 
rate" of the Bank of America, NT & SA, from time to time in effect ("Prime
Rate"), but in no event at a rate higher than that permitted by applicable law.

               (e)  On or prior to the first redemption date, this Corporation
shall deposit with a bank or trust company in San Francisco, California having a
capital and surplus of at least $100,000,000, as a trust fund, a sum equal to
the aggregate Redemption Price for all shares of Series A Preferred Stock called
for redemption and not yet redeemed, with irrevocable instructions and authority
to the bank or trust company to pay, on or after the redemption date, the
Redemption Price to the holders upon the surrender of their share certificates.
From and after the date of such deposit, the shares so called for redemption
shall be redeemed. The deposit shall constitute full payment of the shares to
their holders, and from and after the date of the deposit, the shares shall be
deemed to be no longer outstanding, all dividends with respect to such shares
shall cease to accrue and the holders thereof shall cease to be shareholders
with respect to such shares and shall have no rights with respect thereto except
the right to receive from the bank or trust company payment of the Redemption
Price of the shares, without interest, upon surrender of their certificates
therefor, and the right to convert such shares as provided for herein.

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

               (a)  For so long as at least 250,000 shares of Series A Preferred
Stock remain outstanding, the holders of Series A Preferred Stock, voting as a
separate class, shall be entitled to elect one director. Such director shall be
the candidate receiving the highest number of affirmative votes of the
outstanding shares of Series A Preferred Stock (the "Series A Director
Designee") with votes cast against such candidate and votes withheld having no
legal effect. The election of a director by the Series A Preferred Stock shall
occur at the annual meeting of holders of capital stock or at any special
meeting of holders of Series A Preferred Stock called by holders of a majority
of the outstanding shares of Series A Preferred Stock or by the written consent
of all such holders. If the person elected by the holders of Series A Preferred
Stock should cease to be a director for any reason, the vacancy shall only be
filled by the vote or written consent of holders of a majority of the
outstanding shares of Series A Preferred Stock. The holder of each share 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 share of such series of Series
A Preferred Stock could be converted on the record date for the vote or consent
of shareholders and shall vote with holders of the Common Stock upon any matter
submitted to a vote of shareholders, except for the election of directors and
those matters required by law to be submitted to a class vote or pursuant to the
protective provisions set forth herein. The right of the holders of Series A
Preferred Stock to vote, as a separate class, to elect the Series A Director
Designee shall expire on the closing date of the Corporation's initial public
offering.

                                       7.

 
               (b)  Holders of the outstanding shares of Common Stock shall be
entitled to elect the remaining directors of the Corporation.
 
          5.   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 any time after the date of
issuance of such share at the office of this Corporation or any transfer agent
for such shares, into such number of fully paid and nonassessable shares of
Common Stock as is determined by dividing $8.00 (subject to adjustment for any
splits, dividends, subdivisions, combinations, reclassifications and the like
with respect to such shares) (the "Series A Purchase Price") by the Conversion
Price at the time in effect for such share. The initial Conversion Price per
share shall be the Series A Purchase Price. The Conversion Price shall be
subject to the adjustments set forth below.
 
                    (ii)   Each share of Series A Preferred Stock shall
automatically be converted into shares of Common Stock as determined from time
to time, (a) at the then effective Conversion Price immediately upon the closing
of an underwritten public offering covering this Corporation's Common Stock at a
minimum gross offering price of $9.00 per share (subject to adjustment for any
splits, dividends, subdivisions, combinations, reclassifications and the like
with respect to such shares) in which this Corporation receives $20,000,000 or
more in net proceeds after deduction of expenses relating to such offering; or
(b) upon this Corporation's receipt of the written consent of the holders of at
least two-thirds of the then outstanding shares of Series A Preferred Stock to
the conversion of all then outstanding Series A Preferred Stock under this
Section.

                    (iii)  No fractional shares of Common Stock shall be issued
upon conversion of Series A Preferred Stock. Any fractional share of Common
Stock (based on the aggregate number of shares of Series A Preferred Stock the
holder is converting at the time) shall be redeemed for the then effective
Conversion Price payable as promptly as possible whenever funds are legally
available therefor.

               (b)  Mechanics of Conversion.  Before any holder of Series A
                    -----------------------
Preferred Stock shall be entitled to convert the same into shares of Common
Stock, he or it shall surrender the certificate therefor, duly endorsed, at the
office of this Corporation or of any transfer agent for the Series A Preferred
Stock, and shall give written notice to this Corporation at such office that he
elects to convert the same. This Corporation shall, as soon as practicable
thereafter, issue and deliver at such office to such holder of Series A
Preferred Stock a certificate or certificates for the number of shares of Common
Stock to which he or it shall be entitled as aforesaid. Such

                                       8.

 
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 entitled to receive the shares of Common Stock
issuable upon such conversion shall be treated for all purposes as the record
holder of such shares of Common Stock on such date.  If the conversion is in
connection with an underwritten offering of securities pursuant to the
Securities Act of 1933, as amended, the conversion may, at the option of any
holder tendering shares of Series A Preferred Stock for conversion, be
conditioned upon the closing with the underwriters of the sale of securities
pursuant to such offering, in which event the person(s) entitled to receive the
Common Stock upon conversion of the Series A Preferred Stock shall not be deemed
to have converted such Series A Preferred Stock until immediately prior to the
closing of such sale of securities.

               (c)  Adjustments to Conversion Price.
                    -------------------------------

                  (i)    Adjustments to Conversion Price Upon Certain Public
                         ---------------------------------------------------
Offerings.  In the event of an underwritten public offering covering this
- ---------
Corporation's Common Stock at a gross offering price to the Corporation of less
than $12.00 per share (subject to adjustment for any splits, dividends,
subdivisions, combinations, reclassifications and the like with respect to such
shares), the Conversion Price shall be adjusted in accordance with the following
table (each of which per share price shall be subject to adjustment for any
splits, dividends, subdivisions, combinations, reclassifications and the like
with respect to such shares):

                                                              EFFECTIVE
PUBLIC OFFERING PRICE PER SHARE ("OFFERING PRICE")        CONVERSION PRICE
- --------------------------------------------------        ----------------

     Greater than $11.00 but less
     than $12.00                                         $7.75 (except as set
                                                               in (c)(ii) below)
     Greater than $10.00 but less
     than or equal to $11.00                             $7.10

     Less than or equal to $10.00                        $6.80

                    (ii)   Notwithstanding the foregoing, the Conversion Price
with respect to an Offering Price greater than $11.00 per share but less than
$12.00 per share shall be determined as follows: if such offering with such
valuation is consummated within one year from the original issuance of the
Series A Preferred Stock, the Conversion Price shall be $7.75 per share. If such
offering with such valuation is consummated more than one year from such
original issuance date, the Conversion Price shall be $7.60 per share.

                                       9.

 
                    (iii)  Adjustments for Stock Dividends, Subdivisions,
                           ----------------------------------------------
Combinations or Consolidation of Common Stock.  In the event of a dividend on
- ---------------------------------------------
shares of Common Stock paid in shares of Common Stock or in the event the
outstanding shares of Common stock shall be subdivided (by stock split or
otherwise), into a greater number of shares, the Conversion Price then in effect
shall, concurrently with the record date of such stock dividend or the
effectiveness of such subdivision, be proportionately decreased. In the event
the outstanding shares of Common Stock shall be combined or consolidated, by
reclassification or otherwise, into a lesser number of shares of Common, the
Conversion Price then in effect shall, concurrently with the effectiveness of
such combination or consolidation, be proportionately increased.

                    (iv)   Adjustments for Other Distributions.  In the event
                           -----------------------------------
this Corporation at any time or from time to time makes, or fixes a record date
for the determination of holders of Common Stock entitled to receive any
distribution payable in securities of this Corporation other than shares of
Common Stock, then and in each such event provision shall be made so that the
holders of Series A Preferred Stock shall receive upon conversion thereof, in
addition to the number of shares of Common Stock receivable thereupon, the
amount of securities of this Corporation which they would have received had
their Series A Preferred Stock been converted into Common Stock on the date of
such event and had they thereafter, during the period from the date of such
event to and including the date of conversion, retained such securities
receivable by them as aforesaid during such period, subject to all other
adjustments called for during such period under this Section 5 with respect to
the rights of the holders of the Series A Preferred Stock.

                    (v)    Adjustments for Reorganization, Reclassification,
                           -------------------------------------------------
Exchange and Subdivisions.  If the shares of Common Stock issuable upon
- -------------------------
conversion of the Series A Preferred Stock shall be changed into the same or a
different number of shares of any other class or classes of stock or other
securities or property whether by reorganization, reclassification or otherwise
(other than a subdivision or combination of shares provided for above), the
Conversion Price then in effect shall, concurrently with the effectiveness of
such reorganization or reclassification, be proportionately adjusted such that
the Series A Preferred Stock shall be convertible into, in lieu of the number of
shares of Common Stock which the holders would otherwise have been entitled to
receive, a number of shares of such other class or classes of stock or
securities or other property equivalent to the number of shares of Common Stock
that would have been subject to receipt by the holders upon conversion of the
Series A Preferred Stock immediately before such event; and, in any such case,
appropriate adjustment (as determined by the board of directors) shall be made
in the application of the provisions herein set forth with respect to the rights
and interest thereafter of the holders of the Series A Preferred Stock, to the
end that the provisions set forth herein (including provisions with respect to
changes in and other adjustments of the Conversion Price) shall thereafter be
applicable, as nearly as reasonably may be, in relation to any shares

                                      10.

 
of stock or other property thereafter deliverable upon the conversion of the
Series A Preferred Stock.
 
               (d)  No Impairment.  This Corporation will not, by amendment of
                    -------------
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, 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 this Corporation but will at all times in good faith assist in the
carrying out of all the provisions of this Section 5 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.
 
               (e)  Certificate as to Adjustments.  Upon the occurrence of each
                    -----------------------------
adjustment or readjustment of the Conversion Price pursuant to this Section 5,
this Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
Series A Preferred Stock a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. This Corporation shall, upon the written request at any
time of any holder of Series A Preferred Stock, furnish or cause to be furnished
to such holder a like certificate setting forth (i) such adjustments and
readjustments, (ii) the Conversion Price at the time in effect, and (iii) the
number of shares of Common Stock and the amount, if any; of other property which
at the time would be received upon the conversion of Series A Preferred Stock.

Corporation shall at all times reserve and keep available out of its authorized

conversion of the shares of the Series A Preferred Stock such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all then outstanding shares of the Series A Preferred Stock; and
if at any time the number of authorized but unissued shares of Common Stock
shall not be sufficient to effect the conversion of all then outstanding shares
of the Series A Preferred Stock, this Corporation will take such corporate
action as may, be necessary to increase its authorized but unissued shares of
Common Stock to such number of shares as shall be sufficient for such purpose.
