                          PREFERENCES AND PRIVILEGES OF

                       SERIES A CONVERTIBLE PREFERRED STOCK

                                        OF

                                   GENUS, INC.


     The undersigned, Mary F. Bobel and Mario M. Rosati, do hereby certify that:

     H.   They are the duly elected and acting Executive Vice President and 
Chief Financial Officer, and Secretary, respectively, of Genus, Inc., a 
California corporation (the "Corporation").

     I.   Pursuant to the authority conferred upon the Board of Directors by 
the Restated Articles of Incorporation of the Corporation, the said Board of 
Directors on January 26, 1998, adopted the following resolution creating a 
series of 100,000 shares of Preferred Stock designated as Series A 
Convertible Preferred Stock:

     "RESOLVED, that pursuant to the authority vested in the Board of 
Directors of the Corporation by the Restated Articles of Incorporation, the 
Board of Directors does hereby provide for the issue of a series of Preferred 
Stock of the Corporation to be designated "Series A Convertible Preferred 
Stock" initially consisting of 100,000 shares, and to the extent that the 
designations, powers, preferences and relative and other special rights and 
the qualifications, limitations and restrictions of the Series A Convertible 
Preferred Stock are not stated and expressed in the Restated Articles of 
Incorporation, does hereby fix and herein state and express such 
designations, powers, preferences and relative and other special rights and 
the qualifications, limitations and restrictions thereof, as follows (all 
terms used herein which are defined in the Restated Articles of Incorporation 
shall be deemed to have the meanings provided therein):

     
          Section 1.     DESIGNATION, AMOUNT AND PAR VALUE.  The series of 
preferred stock shall be designated as 6% Series A Convertible Preferred 
Stock (the "PREFERRED STOCK"), and the number of shares so designated shall 
be 100,000.  Each share of Preferred Stock shall have no par value and a 
stated value of $50.00 per share (the "STATED VALUE").

          Section 2.     DIVIDENDS.

          (a)  Each Holder of Preferred Stock ("HOLDER") shall be entitled to 
receive, when and as declared by the Board of Directors out of funds legally 
available therefor, and the Company shall pay, cumulative dividends at the 
rate per share (as a percentage of the Stated Value per share) equal to 6% 
per annum, payable, in cash or shares of Common Stock (as defined in Section 
8) at (subject to the terms and conditions set fort herein) the option of the 
Company.  Dividends on the Preferred Stock shall be due and payable on each 
yearly anniversary of the Original Issue Date (each a "DIVIDEND PAYMENT 
DATE"), and any dividends not paid on any Dividend Payment Date shall accrue 
and shall be due and payable upon conversion of the Preferred Stock.  No 
dividends shall be due and payable for any partial year period for which the 
Dividend Payment Date has not yet occurred.  A party that holds shares of 
Preferred Stock on a Dividend Payment Date will be entitled to receive such 
dividend payment and any other accrued and unpaid dividends which accrued 
prior to such Dividend Payment Date, without regard to any sale or 
disposition of such 



Preferred Stock subsequent to the applicable record date. All overdue accrued 
and unpaid dividends and other amounts due herewith shall entail a late fee 
at the rate of 15% per annum (to accrue daily, from the date such dividend is 
due hereunder through and including the date of payment).  Except as 
otherwise provided herein, if at any time the Company pays less than the 
total amount of dividends then accrued on account of the Preferred Stock or 
on account of the Company's 6% Series B Convertible Preferred Stock (which 
would be the next series of preferred stock authorized by the Board of 
Directors pursuant to the proper filing of a Certificate of Determination 
setting forth the rights, preferences and privileges of such series) (the 
"SERIES B PREFERRED STOCK"), if issued, which may be purchased pursuant to 
the Purchase Agreement,  such payment shall be distributed ratably among the 
Holders and the holders of the Series B Preferred Stock (the "PREFERRED 
HOLDERS") based upon the number of shares held by each Preferred Holder.  The 
Company shall provide the Holders notice of its intention to pay dividends in 
cash or shares of Common Stock not less than 10 Trading Days prior to the 
Dividend Payment Date for so long as shares of Preferred Stock are 
outstanding. If dividends are paid in shares of Common Stock, the number of 
shares of Common Stock payable as such dividend to each Holder shall be equal 
to the cash amount of such dividend payable to such Holder on such Dividend 
Payment Date divided by the closing bid price of the Common Stock on the 
Trading Day prior to such Dividend Payment Date ("DIVIDEND CONVERSION 
PRICE"), further provided that the Dividend Conversion Price shall not be 
less than $3.47.     

          (b)  Notwithstanding anything to the contrary contained herein, the 
Company may not issue shares of Common Stock in payment of dividends (and 
must deliver cash in respect thereof) on the Preferred Stock if:

               (i)   the number of shares of Common Stock at the time 
authorized, unissued and unreserved for all purposes is insufficient to pay 
such dividends in shares of Common Stock;

               (ii)  the shares of Common Stock to be issued in respect of 
such dividends are not registered for resale pursuant to an effective 
registration statement that names the recipient of such dividend as a selling 
stockholder thereunder (unless such registration statement is not declared 
effective solely as a result of the actions of the recipient of such dividend 
or if such recipient has failed to provide the Company with the necessary 
selling shareholder information to be included in such registration 
statement) and may not be sold without volume restrictions pursuant to Rule 
144 promulgated under the Securities Act of 1933, as amended (the "SECURITIES 
ACT"), as determined by counsel to the Company pursuant to a written opinion 
letter, addressed to the Company's transfer agent in the form and substance 
acceptable to the Holder;

               (iii) the shares of Common Stock to be issued in respect of 
such dividends are not listed on the Nasdaq Stock Market or any other 
exchange or quotation system on which the Common Stock is then listed for 
trading; 

               (iv)  the Company has failed to timely satisfy its obligations 
pursuant to any Conversion Notice (as defined in Section 5(a)(ii)). 
 
          (c)  So long as any Preferred Stock shall remain outstanding, 
neither the Company nor any subsidiary thereof shall redeem, purchase or 
otherwise acquire directly or indirectly any Junior Securities (as defined in 
Section 8), nor shall the Company directly or indirectly pay or declare any 
dividend or make any distribution (other than a dividend or distribution 
described in Section 5) upon, nor shall any distribution be made in respect 
of, any Junior Securities, nor shall any monies be set aside for or applied 
to the purchase or redemption (through a sinking fund or otherwise) of any 
Junior Securities or shares pari passu with the Preferred Stock, except for 
repurchases effected by the Company on the open market, pursuant to a direct 
stock purchase plan.


                                      -2-



          Section 3.     VOTING RIGHTS.

          (a)  Except as otherwise provided herein and as otherwise required 
by law, the Preferred Stock shall have no voting rights.  However, so long as 
any shares of Preferred Stock are outstanding, the Company shall not and 
shall cause its subsidiaries not to, without the affirmative vote of the 
Holders of all of the shares of the Preferred Stock then outstanding,(a) 
alter or change adversely the powers, preferences or rights given to the 
Preferred Stock, (b) alter or amend this Certificate of Determination, (c) 
authorize or create any class of stock ranking as to dividends or 
distribution of assets upon a Liquidation (as defined in Section 4) or 
otherwise senior to or pari passu with the Preferred Stock, except for any 
series of Preferred Stock issued and sold in accordance with the Purchase 
Agreement, (d) amend its Articles of Incorporation, bylaws or other charter 
documents so as to affect adversely any rights of any Holders, (e) increase 
the authorized number of shares of Preferred Stock and (f) enter into any 
agreement with respect to the foregoing.
 
          (b)(i)     If the Company shall have defaulted on any of its 
conversion obligations, registration obligations or payment obligations 
hereunder, and such default has continued for 180 days, then on the 181st day 
of the continuance of such default, without the requirement of any additional 
action by the Company's Board of Directors or stockholders, the fixed number 
of directors constituting the Company's Board of Directors shall be 
automatically increased, pursuant to the authority of the Board of Directors 
to adjust the fixed number of directors within the authorized minimum and 
maximum numbers as stated in the Company's Bylaws, by one directorship and 
the Preferred Holders, voting together as a single class, shall be entitled 
to elect the director to fill the resulting vacancy on the Company's Board of 
Directors.  At elections for such director, each Preferred Holder shall be 
entitled to one vote for each share of Preferred Stock or Series B Preferred 
Stock held. Such right to vote as a single class to elect directors shall, 
when vested, continue until all defaults which triggered such right have been 
completely cured, and when so cured such right to elect such director 
separately as a separate class shall cease.

               (ii)  Whenever such voting right shall have vested, such right 
may be exercised initially either, at a special meeting of the Preferred 
Holders called as hereinafter provided or at any annual meeting of 
stockholders held for the purpose of electing directors, and thereafter at 
such meetings or by the written consent of such holders pursuant to the 
California Corporations Code.

               (iii) At any time when the voting right granted by this 
Section 3(b) shall have vested in the Preferred Holders entitled to vote 
thereon, and if such right shall not already have been initially exercised, 
an officer of the Corporation shall, upon written request of Preferred 
Holders of record of 10% in the aggregate, of shares of Preferred Stock and 
Series B Preferred Stock then outstanding, addressed to the Chief Financial 
Officer of the Corporation, call a special meeting of Preferred Holders.  
Such meeting shall be held at the earliest practicable date upon the notice 
required for annual meetings of stockholders at the place for holding annual 
meetings of stockholders of the Corporation or, if none, at a place 
designated by the Chief Financial Officer of the Corporation.  If notice of 
such meeting is not mailed within 30 days after such written request is 
mailed to the Chief Financial Officer of the Corporation, by registered mail, 
addressed to the Chief Financial Officer of the Corporation at its principal 
office (such mailing to be evidenced by the registry receipt issued by the 
postal authorities), then the Preferred Holders of record of 10% of the 
shares of the Preferred Stock and the Series B Preferred Stock then 
outstanding may designate in writing any person to call such meeting at the 
expense of the Corporation, and such meeting may be called by such person so 
designated upon the notice required for annual meetings of stockholders and 
shall be held at the same place as is elsewhere provided in this paragraph 
3(b)(iii).  Any Preferred Holder that would be entitled to vote at such 
meeting shall have access to the stock record books of the Corporation for 
the purpose of causing a meeting of stockholders to be called pursuant to the 
provisions of this paragraph 3(b)(iii).  Notwithstanding the provisions of 
this paragraph, however, no such special meeting shall be called or held 
during a period within 30 days immediately preceding the date fixed for the 
Corporation's next annual meeting of stockholders. 


                                      -3-



               (iv) The directors elected pursuant to this paragraph 3(b) 
shall serve until the next annual meeting or until their respective 
successors shall be elected and shall qualify, unless earlier terminated as 
set forth below.  Any director elected by the Preferred Holders may be 
removed by, and shall not be removed otherwise than by, the vote of the 
Preferred Holders of a majority of the outstanding shares of the Preferred 
Stock and the Series B Preferred Stock who were entitled to participate in 
such election of directors, voting as a special class, at a meeting called 
for such purpose or by written consent as permitted by law and the Articles 
of Incorporation and By-laws of the Corporation.  If the office of the 
director elected by the Preferred Holders, voting as a class, becomes vacant 
by reason of death, resignation, retirement, disqualification or removal from 
office or otherwise, the Preferred Holders in accordance with the above 
procedures, voting as a class, shall elect a successor director who shall 
hold office for the unexpired term in respect of which such vacancy occurred. 
Upon any termination of the right of the Preferred Holders to vote for 
directors as herein provided, the term of office of all directors then in 
office elected by the Preferred Holders, voting as a class, shall terminate 
immediately.  Whenever the terms of office of the directors elected by the 
Preferred Holders shall have expired, the number of directors shall be such 
number as may be provided for pursuant to the By-laws of the Corporation 
irrespective of any increase made pursuant to the provisions of this Section 
3(b).

               (v)  So long as any shares of Preferred Stock or Series B 
Preferred Stock are outstanding, the By-laws shall contain no provisions that 
would restrict the exercise, by the Preferred Holders of the right to elect 
directors under the circumstances provided in Section 3(b)(i) above.     

          Section 4.     LIQUIDATION.  Upon any liquidation, dissolution or 
winding-up of the Company, whether voluntary or involuntary (a 
"LIQUIDATION"), the Holders shall be entitled to receive out of the assets of 
the Company, whether such assets are capital or surplus, for each share of 
Preferred Stock an amount equal to the Stated Value plus all due but unpaid 
dividends per share, whether declared or not, before any distribution or 
payment shall be made to the holders of any Junior Securities, and if the 
assets of the Company shall be insufficient to pay in full such amounts, then 
the entire assets to be distributed to the Holders of Preferred Stock shall 
be distributed among the Preferred Holders ratably in accordance with the 
respective amounts that would be payable on such shares if all amounts 
payable thereon were paid in full.  A sale, conveyance or disposition of all 
or substantially all of the assets of the Company or the effectuation by the 
Company of a transaction or series of related transactions in which more than 
50% of the voting power of the Company is disposed of, or a consolidation or 
merger of the Company with or into any other company or companies shall not 
be treated as a Liquidation, but instead shall be subject to the provisions 
of Section 5.  The Company shall mail written notice of any such Liquidation, 
not less than 45 days prior to the payment date stated therein, to each 
record Holder of Preferred Stock.

          Section 5.     CONVERSION.

          (a)(i)  Each share of Preferred Stock shall be convertible into 
shares of Common Stock (subject to reduction pursuant to Section 5(a)(iii) 
and Section 3.16 of the Purchase Agreement) at the Conversion Ratio (as 
defined in Section 8) at the option of the Holder in whole or in part at any 
time after the Original Issue Date.  The Holders shall effect conversions by 
surrendering the certificate or certificates representing the shares of 
Preferred Stock to be converted to the Company, or its agent, together with 
the form of conversion notice attached hereto as EXHIBIT A (the "HOLDER 
CONVERSION NOTICE").  Each Holder Conversion Notice shall specify the number 
of shares of Preferred Stock to be converted and the date on which such 
conversion is to be effected, which date may not be prior to the date the 
Holder delivers such Holder Conversion Notice by facsimile (the "HOLDER 
CONVERSION DATE").  If no Holder Conversion Date is specified in a Holder 
Conversion Notice, the Holder Conversion Date shall be the date that the 
Holder Conversion Notice is deemed delivered pursuant to Section 5(h).  
Subject to Sections 5(b) and 5(a)(iii) hereof, each Holder Conversion Notice, 
once given, shall be irrevocable.  If the Holder is converting less than all 
shares of Preferred Stock represented by the certificate or certificates 
tendered by the Holder with the Holder 


                                      -4-



Conversion Notice, or if a conversion hereunder cannot be effected in full 
for any reason, the Company shall promptly deliver to such Holder (in the 
manner and within the time set forth in Section 5(b)) a certificate for such 
number of shares as have not been converted.

               (ii)  On the second anniversary of the Original Issue Date or 
thereafter, the Company may require the conversion of all, but not less than 
all, of the then outstanding and unconverted shares of Preferred Stock with 
such conversion being effectuated at the Conversion Price then in effect 
(subject to reduction pursuant to Section 5(a)(iii)) by delivering to the 
Holder of such shares to be converted a notice in the form attached hereto as 
EXHIBIT B (the "COMPANY CONVERSION NOTICE"), PROVIDED, that, no such 
conversion is permitted unless at the time of the delivery of the Company 
Conversion Notice and on the Company Conversion Date (as defined below), (a) 
the Company shall have complied in all material respects with its obligations 
under the Registration Rights Agreement, (b) the Company was at the time of 
the issuance of the Preferred Stock and the Company is at the time of the 
conversion of the Preferred Stock a "listed corporation" as defined in 
subdivision (d) of Section 301.5 of the California Corporations Code, (c) the 
shares of Common Stock issuable upon such conversion are listed for trading 
on the Nasdaq Stock Market or any other exchange or quotation system on which 
the Common Stock is then listed for trading as such is defined by subdivision 
(d) of Section 301.5 of the California Corporations Code, (d) the Company is 
in compliance with all of its obligations under this Certificate of 
Determination, the Purchase Agreement and the Registration Rights Agreement, 
and (e) the closing bid price of the Common Stock for at least 20 of the 30 
Trading Days immediately preceding the date of the Company Conversion Notice 
shall have been at least 150% of the Conversion Price on the Original Issue 
Date.  Each Company Conversion Notice shall specify the date on which such 
conversion is to be effected, which date may not be prior to the day after 
the Company delivers such Company Conversion Notice by facsimile or later 
than 10 Trading Days subsequent to such delivery (the "COMPANY CONVERSION 
DATE").  If no Company Conversion Date is specified in a Company Conversion 
Notice, the Company Conversion Date shall be the date that the Company 
Conversion Notice is deemed delivered pursuant to Section 5(h).  A Holder 
Conversion Date and a Company Conversion Date are sometimes referred to 
herein as the "CONVERSION DATE" and a Holder Conversion Notice and a Company 
Conversion Notice are sometimes referred to as a "CONVERSION NOTICE."  Any 
conversion pursuant to this Section 5(a)(ii) shall be subject to Section 5(b) 
with respect to consequences of the Company's failure to deliver shares of 
Common Stock in respect of a conversion under this Section.  If a conversion 
hereunder cannot be effected in full for any reason, the Company shall 
promptly deliver to such tendering Holder (in the manner and within the time 
set forth in Section 5(b)) a certificate for such number of shares of 
Preferred Stock as have not been converted.

               (iii)  If on the Conversion Date applicable to any conversion, 
(A) the Common Stock is then listed for trading on the Nasdaq Stock Market, 
the American Stock Exchange or the Nasdaq SmallCap Market, (B) the Conversion 
Price then in effect is such that the aggregate number of shares of Common 
Stock that would then be issuable upon conversion of all outstanding shares 
of Preferred Stock and Series B Preferred Stock, if issued, together with any 
shares of Common Stock previously issued upon conversion of Preferred Stock 
or Series B Preferred Stock, if issued, and in respect of payment of 
dividends hereunder or thereunder and shares of Common Stock issuable upon 
the exercise of Warrants, would equal or exceed 19.999% of the number of 
shares of Common Stock outstanding on the Original Issue Date (the "ISSUABLE 
MAXIMUM"), and (C) the Company has not previously obtained Shareholder 
Approval (as defined below), then the Company shall deliver to the Holder 
seeking conversion a notice within two Trading Days of receiving such 
conversion request of the Company's intention to either (1) issue to any 
Holder so requesting conversion of Preferred Stock its pro rata portion of 
the Issuable Maximum in the same ratio that the number of shares of Preferred 
Stock held by any such Holder bears to all shares of Preferred Stock then 
outstanding and, with respect to any shares of Common Stock that otherwise 
would have been issuable to such Holder in respect of the Conversion Notice 
at issue or in respect of payment of dividends hereunder in excess of the 
Issuable Maximum, the Holder may require the Company to, as promptly as 
possible, but in no event later than 60 days after notice from such Holder 
convene a meeting of the holders of the Common Stock and use its best efforts 
to obtain the Shareholder Approval; provided that in no event shall such 
meeting be required to occur prior to May 31, 1998, or (2) redeem as 


                                      -5-



soon as reasonably possible, but in any event within seven days of such 
notice, from funds legally available therefor at the time of such redemption, 
the balance of the Preferred Stock subject to such Conversion Notice at a 
price per share equal to the product of (i) the average Per Share Market 
Value for the five (5) Trading Days immediately preceding (x) the Conversion 
Date or (y) the date of payment in full by the Company of such redemption 
price, whichever is greater, and (ii) the Conversion Ratio calculated on the 
Conversion Date; PROVIDED, HOWEVER, that if the Holder has requested that the 
Company obtain Shareholder Approval under clause (1) above and the Company 
fails for any reason to obtain such Shareholder Approval within the time 
period set forth in clause (1) above, the Company shall be obligated to 
redeem as promptly as reasonably possible but in any event within seven days 
of such failure the Preferred Stock not converted as a result of the 
provisions of this Section in accordance with the provisions of clause (2) 
above.  If the Company is obligated to redeem shares of Preferred Stock 
pursuant to this Section and the Company fails for any reason to pay the 
redemption price within the time periods set forth above, the Company will 
pay a late fee on such redemption price at a rate of 15% per annum to the 
converting Holder of Preferred Stock, accruing from the Conversion Date until 
the redemption price plus any accrued late fees thereon is paid in full.  The 
entire redemption price, including late fees thereon, shall be paid in cash. 
"SHAREHOLDER APPROVAL" means the approval by a majority of the total votes 
cast on the proposal, in person or by proxy, at a meeting of the shareholders 
of the Company held in accordance with the Company's Articles of 
Incorporation and by-laws, of the issuance by the Company of shares of Common 
Stock exceeding the Issuable Maximum as a consequence of the conversion of 
Preferred Stock and exercise of the Warrants into Common Stock at a price 
less than the greater of the book or market value on the Original Issue Date 
as and to the extent required pursuant to Rule 4460(i) of the Nasdaq Stock 
Market or Rule 713 of the American Stock Exchange (or any successor or 
replacement provision thereof), as applicable.

          (b)  Not later than three Trading Days after any Conversion Date, 
the Company will deliver to the Holder (i) a certificate or certificates 
which shall be free of restrictive legends and trading restrictions (other 
than those required by Section 3.1(b) of the Purchase Agreement) representing 
the number of shares of Common Stock being acquired upon the conversion of 
shares of Preferred Stock (subject to reduction pursuant to Section 5(a)(iii) 
and Section 3.16 of the Purchase Agreement), (ii) one or more certificates 
representing the number of shares of Preferred Stock not converted, (iii) a 
bank check in the amount of accrued and unpaid dividends, if any (if the 
Company has elected to pay accrued dividends in cash) and (iv) if the Company 
has elected to pay accrued dividends in shares of Common Stock, certificates, 
which shall be free of restrictive legends and trading restrictions (other 
than those required by Section 3.1 (b) of the Purchase Agreement), 
representing such number of Shares of Common Stock as equals such dividend 
divided by the Conversion Price on the Dividend Payment Date; PROVIDED, 
HOWEVER, that the Company shall not be obligated to issue certificates 
evidencing the shares of Common Stock issuable upon conversion of any shares 
of Preferred Stock until certificates evidencing such shares of Preferred 
Stock are either delivered for conversion to the Company or any transfer 
agent for the Preferred Stock or Common Stock, or the Holder of such 
Preferred Stock notifies the Company that such certificates have been lost, 
stolen or destroyed and provides a bond (or other adequate security) 
reasonably satisfactory to the Company to indemnify the Company from any loss 
incurred by it in connection therewith.  The Company shall, upon request of 
the Holder, use its best efforts to deliver any certificate or certificates 
required to be delivered by the Company under this Section electronically 
through the Depository Trust Corporation or another established clearing 
corporation performing similar functions, if available.  If in the case of 
any Conversion Notice such certificate or certificates, including for 
purposes hereof, any shares of Common Stock to be issued on the Conversion 
Date on account of accrued but unpaid dividends hereunder, are not delivered 
to or as directed by the applicable Holder by the third Trading Day after the 
Conversion Date, the Holder shall be entitled by written notice to the 
Company at any time on or before its receipt of such certificate or 
certificates thereafter, to rescind such conversion, in which event the 
Company shall immediately return the certificates representing the shares of 
Preferred Stock tendered for conversion.  If the Company fails to deliver to 
the Holder such certificate or certificates pursuant to this Section, 
including for purposes hereof, any shares of Common Stock to be issued on the 
Conversion Date on account of accrued but unpaid dividends hereunder, on or 
prior to the third Trading Day after the Conversion Date, the Company shall 
pay to such Holder, in cash, as liquidated damages and not as a 


                                      -6-



penalty, $5,000 for each day after such third Trading Day until such 
certificates are delivered.  If the Company fails to deliver to the Holder 
such certificate or certificates pursuant to this Section prior to the 10th 
day after the Conversion Date, the Company shall, at the Holder's option (i) 
redeem, from funds legally available therefor at the time of such redemption, 
such number of shares of Preferred Stock then held by such Holder, as 
requested by such Holder, and (ii) pay all accrued but unpaid dividends on 
account of the Preferred Stock for which the Company shall have failed to 
issue Common Stock certificates hereunder, in cash.  The redemption price 
shall be equal to the sum of (A) the aggregate of all accrued but unpaid 
dividends, plus (B) the number of shares of Preferred Stock then held by such 
Holder multiplied by (1) the average Per Share Market Value for the five (5) 
Trading Days immediately preceding (x) the Conversion Date or (y) the date of 
payment in full by the Company of such prepayment price, whichever is 
greater, multiplied by, (2) the Conversion Ratio calculated on the Conversion 
Date.  If the Holder has requested that the Company redeem shares of 
Preferred Stock pursuant to this Section and the Company fails for any reason 
to pay the redemption price under (2) above within seven days after such 
notice is deemed delivered pursuant to Section 5(i), the Company will pay a 
late fee on the redemption price at a rate of 15% per annum, in cash to such 
Holder, accruing from such seventh day until the redemption price and any 
accrued late fees thereon is paid in full.  Nothing herein shall limit a 
Holder's right to pursue actual damages for the Company's failure to deliver 
certificates representing shares of Common Stock upon conversion within the 
period specified herein (including, without limitation, damages relating to 
any purchase of shares of Common Stock by such Holder to make delivery on a 
sale effected in anticipation of receiving certificates representing shares 
of Common Stock upon conversion, such damages to be in an amount equal to (A) 
the aggregate amount paid by such Holder for the shares of Common Stock so 
purchased MINUS (B) the aggregate amount of net proceeds, if any, received by 
such Holder from the sale of the shares of Common Stock issued by the Company 
pursuant to such conversion), and such Holder shall have the right to pursue 
all remedies available to it at law or in equity (including, without 
limitation, a decree of specific performance and/or injunctive relief).

          (c)(i)    The conversion price for each share of Preferred Stock 
(the "CONVERSION PRICE") in effect on any Conversion Date shall be the lesser 
of (a) 110% of the Per Share Market Value for the Trading Day immediately 
preceding the Original Issue Date (the "INITIAL CONVERSION PRICE") provided 
that the Initial Conversion Price shall not be less than $3.47 or (b) 82% of 
the average of fifteen (15) closing bid prices of the Common Stock on the 
Nasdaq Stock Market or other market or exchange on which the Common Stock is 
then listed or traded, during the forty five (45) Trading Days prior to the 
date of the applicable Conversion Notice, which fifteen closing bid prices 
shall be chosen by the Holder converting such shares of Preferred Stock; 
PROVIDED, HOWEVER, that, (a) if the Underlying Shares Registration Statement 
(as defined in the Registration Rights Agreement) is not filed on or prior to 
March 15, 1998, or (b) the Company fails to file with the Commission a 
request for acceleration in accordance with Rule 12d1-2 promulgated under the 
Securities Exchange Act of 1934, as amended, within five (5) days of the date 
that the Company is notified (orally or in writing, whichever is earlier) by 
the Commission that an Underlying Shares Registration Statement will not be 
"reviewed," or not subject to further review, or (c) if the Underlying Shares 
Registration Statement is not declared effective by the Commission on or 
prior to the 90th day after the Original Issue Date, or (d) if such 
Underlying Shares Registration Statement is filed with and declared effective 
by the Commission but thereafter ceases to be effective as to all Registrable 
Securities (as such term is defined in the Registration Rights Agreement) at 
any time prior to the expiration of the "EFFECTIVENESS PERIOD" (as such term 
as defined in the Registration Rights Agreement), without being succeeded 
within 10 Trading Days by a subsequent Underlying Shares Registration 
Statement filed with and declared effective by the Commission, or (e) if 
trading in the Common Stock shall be suspended for more than three (3) 
consecutive Trading Days or five (5) Trading Days in the aggregate, or (f) if 
the conversion rights of the Holders are suspended for any reason, or (g) if 
the Company breaches in a material respect any covenant or other material 
term or condition to this Agreement, the Purchase Agreement (other than a 
representation or warranty contained therein), the Warrants, the Registration 
Rights Agreement or any other agreement, document, certificate or other 
instrument delivered in connection with the transactions contemplated 
thereby, and such breach continues for a period of thirty (30) days after 
written notice thereof to the Company, or (h) 


                                      -7-



if the Company is required to convene a shareholders meeting pursuant to 
Section 5(a)(iii) and fails to convene a meeting of shareholders within the 
time periods specified in Section 5(a)(iii) or does so convene a meeting of 
shareholders within such time period but fails to obtain Shareholder Approval 
at such meeting, or (i) if the Company has breached Section 3(p) of the 
Registration Rights Agreement (any such failure or breach being referred to 
as an "EVENT," and for purposes of clauses (a), (c) and (f) the date on which 
such Event occurs, or for purposes of clause (b) the date on which such five 
(5) day period is exceeded, or for purposes of clause (d) the date which such 
10 Trading Day-period is exceeded, or for purposes of clause (e) the date on 
which such three Trading Day period is exceeded, or for clause (g) the date 
on which such thirty (30) day period is exceeded, being referred to as "EVENT 
DATE"), the Conversion Price shall be decreased by 2% each month (i.e., the 
Conversion Price would decrease by 2% as of the Event Date and an additional 
2% as of each monthly anniversary of the Event Date) until the earlier to 
occur of the second month anniversary after the Event Date and such time as 
the applicable Event is cured.  Commencing the second month anniversary after 
the Event Date, the Company shall pay to the Holders $50,000 (each Holder 
being entitled to receive such portion of such amount as equals its pro rata 
portion of the Preferred Stock then outstanding) in cash as liquidated 
damages, and not as a penalty on the first day of each monthly anniversary of 
the Event Date until such time as the applicable Event, is cured.  Any 
decrease in the Conversion Price pursuant to this Section shall continue 
notwithstanding the fact that the Event causing such decrease has been 
subsequently cured.  

               (ii)  If the Company, at any time while any shares of 
Preferred Stock are outstanding, shall (a) pay a stock dividend or otherwise 
make a distribution or distributions on shares of its Junior Securities or 
pari passu securities (other than with respect to the Series B Preferred 
Stock) payable in shares of Common Stock, (b) subdivide outstanding shares of 
Common Stock into a larger number of shares, (c) combine outstanding shares 
of Common Stock into a smaller number of shares, or (d) issue by 
reclassification of shares of Common Stock any shares of capital stock of the 
Company, the Initial Conversion Price shall be multiplied by a fraction of 
which the numerator shall be the number of shares of Common Stock outstanding 
before such event and of which the denominator shall be the number of shares 
of Common Stock outstanding after such event.  Any adjustment made pursuant 
to this Section 5(c)(ii) shall become effective immediately after the record 
date for the determination of stockholders entitled to receive such dividend 
or distribution and shall become effective immediately after the effective 
date in the case of a subdivision, combination or re-classification.

               (iii) If the Company, at any time while any shares of 
Preferred Stock are outstanding, shall issue rights or warrants to all 
holders of Common Stock entitling them to subscribe for or purchase shares of 
Common Stock at a price per share less than the Per Share Market Value of 
Common Stock at the record date mentioned below, the Initial Conversion Price 
shall be multiplied by a fraction, of which the denominator shall be the 
number of shares of Common Stock (excluding treasury shares, if any) 
outstanding on the date of issuance of such rights or warrants plus the 
number of additional shares of Common Stock offered for subscription or 
purchase, and of which the numerator shall be the number of shares of Common 
Stock  outstanding on the date of issuance of such rights or warrants plus 
the number of shares which the aggregate offering price of the total number 
of shares so offered would purchase at such Per Share Market Value.  Such 
adjustment shall be made whenever such rights or warrants are issued, and 
shall become effective immediately after the record date for the 
determination of stockholders entitled to receive such rights or warrants.  
However, upon the expiration of any right or warrant to purchase Common Stock 
the issuance of which resulted in an adjustment in the Initial Conversion 
Price pursuant to this Section 5(c)(iii), the Initial Conversion Price shall 
immediately upon such expiration be recomputed, and effective immediately 
upon such expiration, be increased to the price which it would have been (but 
reflecting any other adjustments in the Initial Conversion Price made 
pursuant to the provisions of this SECTION 5 after the issuance of such 
rights or warrants) had the adjustment of the Initial Conversion Price made 
upon the issuance of such rights or warrants been made on the basis of that 
number of shares of Common Stock actually purchased upon the exercise of such 
rights or warrants.

                                      -8-



               (iv)  If the Company, at any time while shares of Preferred 
Stock are outstanding, shall distribute to all holders of Common Stock (and 
not to Holders of Preferred Stock) evidences of its indebtedness or assets or 
rights or warrants to subscribe for or purchase any security (excluding those 
referred to in Sections 5(c)(ii) and (iii) above), then in each such case the 
Conversion Price at which each share of Preferred Stock shall thereafter be 
convertible shall be determined by multiplying the Conversion Price in effect 
immediately prior to the record date fixed for determination of stockholders 
entitled to receive such distribution by a fraction of which the denominator 
shall be the Per Share Market Value of Common Stock determined as of the 
record date mentioned above, and of which the numerator shall be such Per 
Share Market Value of the Common Stock on such record date less the then fair 
market value at such record date of the portion of such assets or evidence of 
indebtedness so distributed applicable to one outstanding share of Common 
Stock as determined by the Board of Directors in good faith; PROVIDED, 
HOWEVER, that in the event of a distribution exceeding ten percent (10%) of 
the net assets of the Company, if the Holders of a majority in interest of 
the Preferred Stock dispute such valuation, such fair market value shall be 
determined by a nationally recognized or major regional investment banking 
firm or firm of independent certified public accountants of recognized 
standing (which may be the firm that regularly examines the financial 
statements of the Company) (an "APPRAISER") selected in good faith by the 
Holders of a majority in interest of the shares of Preferred Stock then 
outstanding; and PROVIDED, FURTHER, that the Company, after receipt of the 
determination by such Appraiser shall have the right to select an additional 
Appraiser, in good faith, in which case the fair market value shall be equal 
to the average of the determinations by each such Appraiser.  In either case 
the adjustments shall be described in a statement provided to the Holders of 
Preferred Stock of the portion of assets or evidences of indebtedness so 
distributed or such subscription rights applicable to one share of Common 
Stock. Such adjustment shall be made whenever any such distribution is made 
and shall become effective immediately after the record date mentioned above.

               (v)   All calculations under this SECTION 5 shall be made to 
the nearest cent or the nearest 1/100th of a share, as the case may be.

               (vi)  Whenever the Conversion Price is adjusted pursuant to 
Section 5(c)(i),(ii),(iii) or (iv), the Company shall promptly mail to each 
Holder of Preferred Stock, a notice setting forth the Conversion Price after 
such adjustment and setting forth a brief statement of the facts requiring 
such adjustment.

               (vii) In case of any reclassification of the Common Stock, any 
consolidation or merger of the Company with or into another person pursuant 
to which (i) a majority of the Company's Board of Directors will not 
constitute a majority of the board of directors of the surviving entity or 
(ii) less than 50% of the outstanding shares of the capital stock of the 
surviving entity will be held by the same shareholders of the Company prior 
to such reclassification, consolidation or merger, the sale or transfer of 
all or substantially all of the assets of the Company or any compulsory share 
exchange pursuant to which the Common Stock is converted into other 
securities, cash or property, the Holders of the Preferred Stock then 
outstanding shall have the right thereafter to convert such shares only into 
the shares of stock and other securities, cash and property receivable upon 
or deemed to be held by holders of Common Stock following such 
reclassification, consolidation, merger, sale, transfer or share exchange, 
and the Holders of the Preferred Stock shall be entitled upon such event to 
receive such amount of securities, cash or property as the shares of the 
Common Stock of the Company into which such shares of Preferred Stock could 
have been converted immediately prior to such reclassification, 
consolidation, merger, sale, transfer or share exchange would have been 
entitled; PROVIDED, HOWEVER, that if such reclassification, consolidation or 
merger is (i) approved by the Company's Board of Directors, and (ii) would 
not prevent the Company from obtaining a pooling of interest treatment as 
evidenced by a certificate to this effect provided to the Holder by the 
Company's independent accountants, each Holder shall have the option to 
require the Company to redeem, from funds legally available therefor at the 
time of such redemption, its shares of Preferred Stock at a price per share 
equal to the product of (i) the average Per Share Market Value for the five 
(5) Trading Days immediately preceding (1) the effective date, the date of 
the closing or the date of the announcement, as the case may be, of the 
reclassification, consolidation, merger, sale, transfer or share 

                                      -9-



exchange the triggering such redemption right or (2) the date of payment in 
full by the Company of the redemption price hereunder, whichever is greater, 
and (ii) the Conversion Ratio calculated on the date of the closing or the 
effective date, as the case may be, of the reclassification, consolidation, 
merger, sale, transfer or share exchange triggering such redemption right, as 
the case may be.  The entire redemption price shall be paid in cash, and the 
terms of payment of such redemption price shall be subject to the provisions 
set forth in Section 6(b).  The terms of any such consolidation, merger, 
sale, transfer or share exchange shall include such terms so as to continue 
to give to the Holder of Preferred Stock the right to receive the securities, 
cash or property set forth in this Section 5(c)(vii) upon any conversion or 
redemption following such consolidation, merger, sale, transfer or share 
exchange.  This provision shall similarly apply to successive 
reclassifications, consolidations, mergers, sales, transfers or share 
exchanges.

               (viii)    If:

                    A.   the Company shall declare a dividend (or any other
                         distribution) on its Common Stock; or

                    B.   the Company shall declare a special nonrecurring cash
                         dividend on or a redemption of its Common Stock; or

                    C.   the Company shall authorize the granting to all holders
                         of the Common Stock rights or warrants to subscribe for
                         or purchase any shares of capital stock of any class or
                         of any rights; or

                    D.   the approval of any stockholders of the Company shall
                         be required in connection with any reclassification of
                         the Common Stock of the Company, any consolidation or
                         merger to which the Company is a party, any sale or
                         transfer of all or substantially all of the assets of
                         the Company, of any compulsory share of exchange
                         whereby the Common Stock is converted into other
                         securities, cash or property; or

                    E.   the Company shall authorize the voluntary or
                         involuntary dissolution, liquidation or winding up of
                         the affairs of the Company;

then the Company shall cause to be filed at each office or agency maintained 
for the purpose of conversion of Preferred Stock, and shall cause to be 
mailed to the Holders of Preferred Stock at their last addresses as they 
shall appear upon the stock books of the Company, at least 20 calendar days 
prior to the applicable record or effective date hereinafter specified, a 
notice stating (x) the date on which a record is to be taken for the purpose 
of such dividend, distribution, redemption, rights or warrants, or if a 
record is not to be taken, the date as of which the holders of Common Stock 
of record to be entitled to such dividend, distributions, redemption, rights 
or warrants are to be determined or (y) the date on which such 
reclassification, consolidation, merger, sale, transfer or share exchange is 
expected to become effective or close, and the date as of which it is 
expected that holders of Common Stock of record shall be entitled to exchange 
their shares of Common Stock for securities, cash or other property 
deliverable upon such reclassification, consolidation, merger, sale, transfer 
or share exchange; PROVIDED, HOWEVER, that the failure to mail such notice or 
any defect therein or in the mailing thereof shall not affect the validity of 
the corporate action required to be specified in such notice.  Holders are 
entitled to convert shares of Preferred Stock during the 20-day period 
commencing the date of such notice to the effective date of the event 
triggering such notice. 

               (ix) If the Company (i) makes a public announcement that it 
intends to enter into a Change of Control Transaction (as defined below) or 
(ii) any person, group or entity (including the Company, but 


                                      -10-



excluding a Holder or any affiliate of a Holder) publicly announces a bona 
fide tender offer, exchange offer or other transaction to purchase 50% or 
more of the Common Stock (such announcement being referred to herein as a 
"MAJOR ANNOUNCEMENT" and the date on which a Major Announcement is made, the 
"ANNOUNCEMENT DATE"), then, in the event that a Holder seeks to convert 
shares of Preferred Stock on or following the Announcement Date, the 
Conversion Price shall, effective upon the Announcement Date and continuing 
through the earlier to occur of the consummation of the proposed transaction 
or tender offer, exchange offer or other transaction and the Abandonment Date 
(as defined below), be equal to the lower of (x) the average Per Share Market 
Value on the five Trading Days immediately preceding (but not including) the 
Announcement Date and (y) the Conversion Price in effect on the Conversion 
Date for such Preferred Stock.  "ABANDONMENT DATE" means with respect to any 
proposed transaction or tender offer, exchange offer or other transaction for 
which a public announcement as contemplated by this paragraph has been made, 
the date upon which the Company (in the case of clause (i) above) or the 
person, group or entity (in the case of clause (ii) above) publicly announces 
the termination or abandonment of the proposed transaction or tender offer, 
exchange offer or another transaction which caused this paragraph to become 
operative.  

          (d)  The Company covenants that it will at all times reserve and 
keep available out of its authorized and unissued Common Stock solely for the 
purpose of issuance upon conversion of Preferred Stock and payment of 
dividends on Preferred Stock, each as herein provided, free from preemptive 
rights or any other actual contingent purchase rights of persons other than 
the Holders of Preferred Stock, not less than such number of shares of Common 
Stock as shall (subject to any additional requirements of the Company as to 
reservation of such shares set forth in the Purchase Agreement) be issuable 
(taking into account the adjustments and restrictions of Section 5(a) and 
Section 5(c)) upon the conversion of all outstanding shares of Preferred 
Stock and payment of dividends hereunder.  The Company covenants that all 
shares of Common Stock that shall be so issuable shall, upon issue, be duly 
and validly authorized, issued and fully paid and nonassessable.

          (e)  Upon a conversion hereunder the Company shall not be required 
to issue stock certificates representing fractions of shares of Common Stock, 
but may if otherwise permitted, make a cash payment in respect of any final 
fraction of a share based on the Per Share Market Value at such time.  If the 
Company elects not, or is unable, to make such a cash payment, the Holder of 
a share of Preferred Stock shall be entitled to receive, in lieu of the final 
fraction of a share, one whole share of Common Stock.

          (f)  The issuance of certificates for shares of Common Stock on 
conversion of Preferred Stock shall be made without charge to the Holders 
thereof for any documentary stamp or similar taxes that may be payable in 
respect of the issue or delivery of such certificate, provided that the 
Company shall not be required to pay any tax that may be payable in respect 
of any transfer involved in the issuance and delivery of any such certificate 
upon conversion in a name other than that of the Holder of such shares of 
Preferred Stock so converted and the Company shall not be required to issue 
or deliver such certificates unless or until the person or persons requesting 
the issuance thereof shall have paid to the Company the amount of such tax or 
shall have established to the satisfaction of the Company that such tax has 
been paid.

          (g)  Shares of Preferred Stock converted into Common Stock shall be 
canceled and shall have the status of authorized but unissued shares of 
undesignated stock.

          (h)  Any and all notices or other communications or deliveries to 
be provided by the Holders of the Preferred Stock hereunder, including, 
without limitation, any Conversion Notice, shall be in writing and delivered 
personally, by facsimile or sent by a nationally recognized overnight courier 
service, addressed to the attention of the Chief Executive Officer of the 
Company at the facsimile telephone number or address of the principal place 
of business of the Company as set forth in the Purchase Agreement.  Any and 
all notices or other communications or deliveries to be provided by the 
Company hereunder shall be in writing and delivered personally, by facsimile 
or sent 


                                      -11-



by a nationally recognized overnight courier service, addressed to each 
Holder of Preferred Stock at the facsimile telephone number or address of 
such Holder appearing on the books of the Company, or if no such facsimile 
telephone number or address appears, at the principal place of business of 
the Holder.  Any notice or other communication or deliveries hereunder shall 
be deemed given and effective on the earliest of (i) the date of 
transmission, if such notice or communication is delivered via facsimile at 
the facsimile telephone number specified in this Section prior to 8:00 p.m. 
(Eastern Standard Time), (ii) the date after the date of transmission, if 
such notice or communication is delivered via facsimile at the facsimile 
telephone number specified in this Section later than 8:00 p.m. (Eastern 
Standard Time) on any date and earlier than 11:59 p.m. (Eastern Standard 
Time) on such date, (iii) upon receipt, if sent by a nationally recognized 
overnight courier service, or (iv) upon actual receipt by the party to whom 
such notice is required to be given.  

          Section 6.     REDEMPTIONS.  

          (a) All outstanding and unconverted shares of Preferred Stock on 
the fifth anniversary of the Original Issue Date may be redeemed at any time 
thereafter by the Company pursuant to this Section 6(a), from funds legally 
available therefor at a price per share equal to the product of (i) the 
average Per Share Market Value for the five (5) Trading Days immediately 
preceding (1) the fifth anniversary of the Original Issue Date or (2) the 
date of payment in full by the Company of the redemption price hereunder, 
whichever is greater, and (ii) the Conversion Ratio calculated on the fifth 
anniversary of the Original Issue Date.  Thereafter, all shares of Preferred 
Stock shall cease to be outstanding and shall have the status of authorized 
but undesignated stock.  The entire redemption price shall be paid in cash.

          (b) If any portion of the applicable redemption price under Section 
6(a) shall not be paid by the Company within seven (7) calendar days after 
the date due, late fees shall accrue thereon at the rate of 15% per annum 
until the redemption price plus all such late fees are paid in full (which 
amount shall be paid as liquidated damages and not as a penalty).  In 
addition, if any portion of such redemption price remains unpaid for more 
than 7 calendar days after the date due, the Holder of the Preferred Stock 
subject to such redemption may elect, by written notice to the Company given 
within 30 days after the date due, to either (i) demand conversion in 
accordance with the formula and the time frame therefor set forth in Section 
5 of all of the shares of Preferred Stock for which such redemption price, 
plus accrued liquidated damages thereof, has not been paid in full (the 
"UNPAID REDEMPTION SHARES"), in which event the Per Share Market Price for 
such shares shall be the lower of the Per Share Market Price calculated on 
the date such redemption price was originally due and the Per Share Market 
Price as of the Holder's written demand for conversion, or (ii) invalidate AB 
INITIO such redemption, notwithstanding anything herein contained to the 
contrary.  If the Holder elects option (i) above, the Company shall within 
three (3) Trading Days of its receipt of such election deliver to the Holder 
the shares of Common Stock issuable upon conversion of the Unpaid Redemption 
Shares subject to such Holder conversion demand and otherwise perform its 
obligations hereunder with respect thereto; or, if the Holder elects option 
(ii) above, the Company shall promptly, and in any event not later than three 
(3) Trading Days from receipt of Holder's notice of such election, return to 
the Holder all of the Unpaid Redemption Shares.  

          Section 7.     PAYMENT RESTRICTIONS.  Notwithstanding any provision 
to the contrary contained herein, if payment of any amounts payable by the 
Company to the Holders hereunder, including, without limitations, any amounts 
payable as dividends, penalties or upon redemption of Preferred Stock would 
be prohibited in the absence of consent from Sumitomo Bank of California 
pursuant to the Company's Credit Agreement dated August 15, 1997 with 
Sumitomo Bank of California, as the same may be amended, supplemented, 
superseded or replaced from time to time, or any replacement facility, then 
the Company shall use its best efforts to obtain such consent as promptly as 
practicable after any such payment is required, and any amounts payable by 
the Company with respect to its obligation to pay any such dividends, 
penalties, or redemption payments shall continue to accrue until such 


                                      -12-



consent is obtained.  Nothing contained in this Section 7 shall be construed 
as a waiver by the Holders of any rights they may have hereunder.
