           Notes to Unaudited Pro Forma Consolidated Financial Statements

(1)  The unaudited pro forma condensed consolidated balance sheet as of June 30,
     1998 gives retroactive effect to the sale of the Company's design services
     business assets as if such transaction had taken place on June 30, 1998. 
     The unaudited pro forma condensed consolidated statement of operations for
     the year ended December 31, 1997 and for the six months ended June 30, 1998
     gives retroactive effect to the sale of the Company's design services
     business assets as if such transaction had taken place on January 1, 1997. 
     Accordingly, the "pro forma" columns exclude the accounts of the design
     services business.  The unaudited pro forma condensed consolidated
     statements of operations exclude the $5.0 million gain on the transaction
     but include interest income on the proceeds of the sale as if the funds
     were available for investment beginning January 1997.

(2)  The net proceeds from the sale were deposited in the Company's bank
     accounts and will be used for general working capital purposes.  In
     November 1997 the Company issued 1,000,000 shares of Series B Convertible
     Preferred Stock for $4,583,000.  Each share is convertible into 4.5825
     shares of Common Stock plus the amount of accrued and unpaid dividends at
     the option of the holder.  The Preferred Stock agreement defines Events of
     Noncompliance, which includes a delisting of the Company's stock from
     Nasdaq National Market System.  On the occurrence of an Event of
     Noncompliance, the Preferred Stock becomes redeemable at the option of the
     holder or convertible at 75% of the stated conversion ratio.  On July 16,
     1998 the Company's listing was moved to the Nasdaq SmallCap Market,
     accordingly the redeemable and convertible Preferred Stock is classified as
     mezzanine financing separate from stockholders equity.

     2.   REPRESENTATIONS AND WARRANTIES OF PURCHASER

          The Purchaser represents and warrants to the Company that: 

          2.1  NO GOVERNMENT RECOMMENDATION OR APPROVAL.  The Purchaser 
understands that no United States federal or state agency, or similar agency 
of any other country, has passed upon or made any recommendation or  
endorsement of the Company or the offering of the Preferred Stock.

          2.2  INTENT.  The Purchaser is purchasing the Preferred Stock for 
its own account and not with a view towards distribution and the Purchaser 
has no present arrangement (whether or not legally binding) at any time to 
sell the Shares to or through any person or entity; provided, however, that 
by making the representations herein, the Purchaser does not agree to hold 
the Shares for any minimum or other specific term and reserves the right to 
dispose of the Shares at any time in accordance with Federal and state 
securities laws applicable to such disposition. The Purchaser understands 
that the Shares must be held indefinitely unless such Shares are subsequently 
registered under the Securities Act or an exemption from registration is 
available. The Purchaser has been advised or is aware of the provisions of 
Rule 144  promulgated under the Securities Act. 

          2.3  SOPHISTICATED INVESTOR.  The Purchaser is a sophisticated 
investor (as described in Rule 506(b)(2)(ii) of Regulation D) and an 
accredited investor (as defined in Rule 501 of Regulation D), and the 
Purchaser has such experience in business and financial matters that it is 
capable of evaluating the merits and risks of an investment in the Preferred 
Stock. The Purchaser acknowledges that the investment in the Preferred Stock 
is speculative and involves a high degree of risk.

          2.4  INDEPENDENT INVESTIGATION.  The Purchaser, in making its 
decision to purchase the Preferred Stock subscribed for hereunder, has relied 
upon an independent investigation made by it and/or its representatives and 
has not relied on any oral or written representations or assurances from the 
Company or any representative or agent of the Company, other than as set 
forth in this Agreement and in the public filings of the Company.  Prior to 
the date hereof, the Purchaser has been furnished with and has reviewed the 
Company's latest proxy statement and Annual Report on Form 10-K sent to the 
Company's stockholders and all documents filed by the Company since March 31, 
1998 pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Securities 
Exchange Act of 1934, as amended (the "Exchange Act"), (such documents are 
collectively referred to in this Agreement as the "Exchange Act Reports"). 
The Purchaser has had a reasonable opportunity to ask questions of and 
receive answers from the Company concerning the Company and the offering of 
securities and has received satisfactory answers to all inquiries it has 


                                       4
<PAGE>
made with respect to the Company and the Shares.  The Purchaser acknowledges 
the price and terms of the Shares offered hereby have been determined by 
negotiation based, in part, on the market price for the Common Stock, and 
does not necessarily bear any relationship to the assets, book value or 
potential performance of the Company or any other recognized criteria of 
value.

          2.5  AUTHORITY.  This Agreement has been duly authorized and 
validly executed, and delivered by the Purchaser and is a valid and binding 
agreement enforceable in accordance with its terms, subject to general 
principles of equity and to bankruptcy or other laws affecting the 
enforcement of creditors' rights generally.

          2.6  NO LEGAL ADVICE FROM COMPANY.  The Purchaser acknowledges that 
it has had the opportunity to review this Agreement and the transactions 
contemplated by this Agreement with his or its own legal counsel and tax 
advisors.  Except for any statements or representations of the Company made 
in this Agreement and in the Exchange Act Reports, the Purchaser is relying 
solely on such counsel and advisors and not on any statements or 
representations of the Company or any of its representative or agents for 
legal, tax or investment advice with respect to this investment, the 
transactions contemplated by this Agreement or the securities laws of any  
jurisdiction.

          2.7  NO BROKERS.  The Purchaser has taken no action which would 
give rise to any claim by any person for brokerage commission, finder's fees 
or similar payments by the Company relating to this Agreement or the 
transactions contemplated hereby.

corporate action, and no further consent or authorization of the Company or 
its Board of Directors or stockholders is required, (iii) this Agreement and

is not being conducted in violation of any law, ordinance or regulations of 
any governmental entity, except for possible violations which either singly 
or in the aggregate do not and will not have a Material Adverse Change.  The 
Company is not required under Federal, state or local law, rule or regulation 
in the United States to obtain any consent, authorization or order of, or

Company as of the dates thereof and the results of operations and cash flows 
for the periods then ended (subject, in the case of unaudited statements, to 
normal year-end audit adjustments which in the aggregate will not be

governmental inquiry or investigation, pending, or, to the best of the

of enabling the Company to satisfy any obligation to issue shares of its 
Common Stock upon conversion of the Preferred Stock.  The number of shares so 
reserved shall be increased to reflect stock splits and stock dividends and 
distributions.

          4.3  LISTING OF SHARES.  The Company hereby agrees, promptly 
following the Closing, to take such action to cause the shares of Common 
Stock issuable upon conversion of the Preferred Stock to be listed on the

Common Stock traded on any principal stock exchange or market, it will 
include the shares of Common Stock issuable upon conversion of the Preferred 
Stock in such application and will take such other action as is necessary or 
desirable to cause the Shares to be listed on such other exchange or market 
as promptly as possible.

          4.4  EXCHANGE ACT REGISTRATION.  The Company will cause its Common 
Stock to continue to be registered under Section 12(g) or 12(b) of the 
Exchange Act, will comply in all respects with its reporting and filing 
obligations under the Exchange Act, and will not take any action or file any 
document (whether or not permitted by the Exchange Act or the rules

other restrictions.

          4.6  CORPORATE EXISTENCE.  The Company will take all steps

          4.7  RIGHT OF FIRST REFUSAL

               (a)  Until such time as the earlier of (i) the date that the 
Company first reports Annual Net Income (as defined below) of Fifteen Million 
Dollars ($15,000,000) and (ii) the date that the Purchaser owns less than 
1,000,000 shares (subject to appropriate adjustment for any stock dividend, 
stock split, combination or similar recapitalization) of common stock, or 
common stock issuable upon conversion of Preferred Stock, the Purchaser shall 
have the right of first refusal to purchase all or part of its pro rata share 
of any New Securities (as defined below) which the Company may, from time to 
time, propose to sell and issue, subject to the terms and conditions set 
forth below.  The Purchaser's pro rata share, for purposes of this Section 
4.7, shall equal a fraction, the numerator of which is the sum of (1) the 
number of shares of common stock then held by such Purchaser, (2) the number 
of shares of common stock issuable upon conversion or exercise of shares 


                                      11

stock then outstanding, (2) the number of shares of common stock issuable 
upon conversion or exercise of then outstanding preferred stock, and (3) the 
total number of shares of common stock issuable upon conversion or exercise 
of all then outstanding convertible securities, options, rights and warrants. 
"Annual Net Income", as used herein, means the net income of the Company for 
a full fiscal year as reported in the Company's audited financial statements 
for such year, adjusted, however, by excluding from revenue for such fiscal 
year any extraordinary or non-recurring revenue and any up-front license fees 
which entitle the licensee-payor to license rights for a period in excess of 
one year.

               (b)  "New Securities" shall mean any shares of capital stock 
of the Company whether now authorized or not, and rights, options or warrants 
to purchase capital stock, and securities of any type whatsoever which are, 
or may become, convertible into capital stock; provided, however, that the 
term "New Securities" does not include:

                    (i)       shares of Preferred Stock issued or issuable to 
the Purchaser pursuant to the terms of this Agreement or the shares of common 
stock issued or issuable upon conversion of such securities;

Preferred Stock; 

                    (iii)     securities issued for the acquisition of 
another corporation by the Company by merger, purchase of substantially all 
the assets of such  corporation or another reorganization resulting in the 
ownership by the Company of not less than a majority of the voting power of 
such corporation;

                    (iv)      shares of common stock issued or issuable to 
directors or employees of or consultants to the Company pursuant to a plan or 
arrangement approved by a majority of the members of the Company's Board of 
Directors then in office; 

                    (v)       shares of common stock issued or issuable to 
Halifax Fund L.P. or Capital Ventures International or their permitted 
transferees, pursuant to warrants outstanding on the date hereof;

                    (vi)      shares of common stock issued or issuable to 
Benjamin Huberman, James Fiebiger and Ton Tanke or their permitted 
transferees, pursuant to warrants outstanding on the date hereof;

                    (vii)     shares of common stock issued or issuable to 
Siemens Aktiengesellschaft ("Siemens"), pursuant to Section 5.1 of that 
certain License Agreement between the Company and Siemens dated October 22, 
1997, or upon the exercise of warrants to purchase shares of common stock 
outstanding on the date hereof;

conversion of shares of the Company's Series B Convertible Preferred Stock; 

                    (ix)      shares of common stock issued or issuable to 
holders of Series B Convertible Preferred Stock pursuant to Section 4.8 of 
the Series B Agreement; or

                    (x)       securities issued as a result of any stock 
split, stock dividend or reclassification of common stock, distributable on a 
pro rata basis to all  holders of common stock.

               (c)  In the event the Company intends to issue New Securities, 
it shall give the Purchaser written notice of such intention, describing the 
type of New Securities to be issued, the price thereof and the general terms 
upon which the Company proposes to effect such issuance.  The Purchaser shall 
have 15 days from the date of its receipt of any such notice to agree to 
purchase all or part of its pro rata share of New Securities for the price 
and upon the general terms and conditions specified in the Company's notice 
by giving written notice to the Company stating the quantity of New 
Securities to be so purchased.  In the event the Purchaser elects not to 
purchase all of its pro rata share of New Securities, the Company may issue 
the New Securities described in the Company's notice within 45 days after the 
expiration of such 15-day period, for the price and upon the general terms 
and conditions specified in the Company's notice to the Purchaser. 

          4.8  SALE OF SHARES UNDER RULE 144.  From and after the Closing, at 
the request of any holder of Shares (or other Registrable Securities (as

in compliance with Rule 144 under the Securities Act, the Company shall (a) 
promptly furnish to such holder a written statement as to its compliance with 
the filing requirements of the SEC as set forth in Rule 144, as the same may 
be amended from time to time, and (b) make such additional filings of reports 
with the SEC as will enable the holders of Registrable Securities to make 
sales thereof pursuant to such Rule.  The Company shall provide its transfer 
agent with appropriate instructions and/or opinions of counsel in order for 
any restrictive legend contained on the certificates for the Shares (or other 
Registrable Securities) to be removed when appropriate and for such holders 
to sell, transfer and/or dispose of the Registrable Securities in accordance 
with Rule 144.

                            REGISTRATION RIGHTS AGREEMENT

     THIS REGISTRATION RIGHTS AGREEMENT ("Registration Rights Agreement"), 
entered into as of August 14, 1998, among GateField Corporation, a Delaware 
corporation with offices at 47100 Bayside Parkway, Fremont, California 94538 
(the "Company"), and the party listed on Exhibit A (the "Purchaser").
                                          
                                W I T N E S S E T H:

     WHEREAS, pursuant to a Stock Purchase Agreement, dated as of August 14, 
1998 (the "Stock Purchase Agreement"), by and between the Company and the 
Purchaser, the Company has agreed to sell and such Purchaser has agreed to 
purchase 300,000 shares of the Company's Series C Convertible Preferred 
Stock, $.10 par value (the "Preferred Stock"), convertible into up to 
2,000,000 shares of Common Stock (the "Shares"). 

     WHEREAS, pursuant to the terms of, and in partial consideration for, the 
Purchaser's agreement to enter into the Stock Purchase Agreement, the Company 
has agreed to provide the Purchaser with certain rights with respect to the 
registration of the Shares under the Securities Act of 1933, as amended (the 
"Securities Act");

     NOW, THEREFORE, in consideration of the mutual promises, 
representations, warranties, covenants and conditions set forth herein, the 
Company and the Purchaser agree as follows:

     1.   CERTAIN DEFINITIONS.  As used in this Registration Rights 
Agreement, the following terms shall have the following respective meanings. 
Other terms used herein which are defined in the Stock Purchase Agreement, 
shall have the same meanings herein as they do in the Stock Purchase 
Agreement.

     "Commission" or "SEC" shall mean the Securities and Exchange Commission, 
or any other Federal agency at the time administering the Securities Act. 

     "Holder" shall include the Purchaser and any transferee of Preferred 
Stock, Shares or Registrable Securities which have not been sold to the 
public, to whom the registration rights covered by this Registration Rights 
Agreement have been transferred in compliance with Section 12 of this 
Registration Rights Agreement.

     "Registrable Securities" shall mean: (i) the Shares, (ii) any shares of 
Common Stock, and any other securities, acquired by the Purchaser pursuant to 
Section 4.7 of the Stock Purchase Agreement, and (iii) and any other shares 
of common stock issued in respect of such shares (because of stock splits, 
stock dividends, reclassifications, recapitalizations, or similar events).  
Wherever reference is made in this Registration Rights Agreement to a request 
or consent of holders of a certain percentage 


<PAGE>

of Registrable Securities, the determination of such percentage shall include 
shares of common stock issuable upon conversion of the Preferred Stock even 
if such conversion has not yet been effected.

     The terms "register," "registered" and "registration" shall refer to a 
registration effected by preparing and filing a registration statement with 
the Commission in compliance with the Securities Act and applicable rules and 
regulations thereunder, and the declaration or ordering of the effectiveness 
of such registration statement.

     "Registration Expenses" shall mean all expenses to be incurred by the 
Company in connection with the Purchaser's exercise of its registration 
rights under this Registration Rights Agreement, including, without 
limitation, all registration and filing fees, printing expenses, fees and 
disbursements of counsel for the Company, blue sky fees and expenses and the 
expenses of any special audits incident to or required by any such 
registration (but excluding the compensation of regular employees of the 
Company, which shall be paid in any event by the Company).

     "Registration Statement" shall mean a registration statement filed by 
the Company with the Commission for a public offering and sale of Common 
Stock (other than a registration statement on Form S-8 or Form S-4, or their 
successors, or any other form for a similar limited purpose, or any 
registration statement covering only securities proposed to be issued in 
exchange for securities or assets of another corporation). 

     "Regulation D" shall mean Regulation D as promulgated pursuant to the 
Securities Act, and as subsequently amended. 

     "Selling Expenses" shall mean all underwriting discounts and selling 
commissions, if any, applicable to the sale of Registrable Securities and all 
fees and disbursements of counsel for the Holder not included within 
"Registration Expenses."

     2.   THE REGISTRATION REQUIREMENTS.  If and when requested by the 
Holders holding in the aggregate at least 30% of the Registrable Securities 
then held by the Holders, but not before August 14, 1999 the Company shall 
file, and use its reasonable best efforts to cause to become effective, as 
promptly as possible and in no event later than 60 days after the date of 
such request, one Registration Statement covering the resale of all the 
Registrable Securities requested by the Holders to be included in such 
registration and shall take all action necessary to qualify the Registrable 
Securities requested by the Holders to be included in such registration under 
state "blue sky" laws as hereinafter provided; PROVIDED, HOWEVER, that the 
Company shall not be required to effect such registrations on more than one 
occasion.  The Company shall use its reasonable best efforts to effect the 
registration contemplated by the foregoing (including, without limitation, 
the execution of an undertaking to file amendments and post-effective 
amendments, appropriate qualification under and compliance with applicable 
blue sky or other state securities laws and appropriate compliance with 
applicable regulations issued under the Securities Act) and as would permit 
or facilitate the sale and distribution of all the Registrable Securities in 
all states reasonably 


<PAGE>
requested by the Holders for purposes of maximizing the proceeds realizable 
by the Holders from such sale and distribution.  Such reasonable best efforts 
by the Company shall include, without limitation, the following:

          (a)  The Company shall file (i) Registration Statements with the 
Commission under the Securities Act registering the Registrable Securities 
for public sale and shall use its reasonable best efforts to cause such 
Registration Statements to become and remain effective for the period of 
time set forth in Section 6 hereof, subject to the provisions of Section 7 
hereof; (ii) such blue sky filings as shall be reasonably requested to permit 
such sales PROVIDED, HOWEVER, that the  Company shall not be required to 
register the Registrable Securities in any jurisdiction that would subject it 
to general service of process in any such jurisdiction where it is not then 
so subject or subject the Company to any tax in any such jurisdiction where 
it is not then so subject or require the Company to qualify to do business in 
any  jurisdiction where it is not then so qualified; and (iii) any required  
filings with the National Association of Securities Dealers, Inc.  ("NASD") 
or exchange where the Registrable Securities are traded; all  as soon as 
practicable after demand is made pursuant to this Section 2.  The Company 
shall use its reasonable best efforts to have the  Registration Statements 
and other filings declared effective as soon thereafter as may be 
practicable.  

          (b)  The Company shall enter into such customary agreements 
(including a customary underwriting agreement with the underwriter or  
underwriters, if any) and take all such other reasonable actions in 
connection therewith in order to expedite or facilitate the disposition of 
such Registrable Securities and in such connection, if the Registrable 
Securities are to be sold in an underwritten offering, the Company shall:  

               (i)       make such representations and warranties to the 
Holders and the underwriter or underwriters in form and substance and scope 
as are customarily made by issuers to underwriters in secondary underwritten 
offerings;

               (ii)      cause to be delivered to the sellers of Registrable 
Securities and the underwriter or underwriters opinions of general counsel to 
the Company, dated the effective day (or in the case of an underwritten 
offering, dated the date of delivery of any Registrable Securities sold 
pursuant thereto) of the applicable Registration Statement, which counsel and 
opinions (in form, scope and substance), shall be reasonably satisfactory to 
the managing underwriter or underwriters and the appointed representative or 
counsel of the Holders, addressed to the Holders and each underwriter 
covering the matters customarily covered in opinions requested in secondary 
underwritten offerings and such other matters as may be reasonably requested 
by the Holders; 

               (iii)     cause to be delivered, immediately prior to the 
effectiveness of the applicable Registration Statement (and at the time of 
delivery of any Registrable Securities sold pursuant thereto), letters from 
the Company's independent certified public accountants addressed to the 
Holders and each underwriter stating that such accountants are independent 
public accountants 


                                       3
<PAGE>
within the meaning of the Securities Act and the applicable published rules 
and regulations thereunder, and otherwise in customary form and covering such 
financial and accounting matters as are customarily covered by letters of the 
independent certified public accountants delivered in connection with 
secondary underwritten public offerings; 

               (iv)      if an underwriting agreement is entered into, use 
its best efforts to cause the same to set forth indemnification and 
contribution provisions and procedures which are no less favorable to the 
Holders and the Company than those contemplated by Sections 8 and 9 of this 
Registration Rights Agreement with respect to all parties to be indemnified 
pursuant to such sections; and 

               (v)       deliver such documents and certificates as may be 
reasonably requested by the Holders of the Registrable Securities being sold 
or the managing underwriter or underwriters to evidence compliance with 
clause (i) above and with any customary conditions contained in the 
underwriting agreement, if any, or other agreement entered into by the 
Company; the foregoing in this Section 2(b) shall be done at each closing 
under  any such underwriting or similar agreement or as to the extent 
required thereunder. 

          (c)  The Company shall make available for inspection and review by 
the Holders, a representative or representatives of the Holders, any 
underwriter participating in any disposition pursuant to a Registration 
Statement, and any attorney or accountant retained by such Holders or  
underwriter, any such Registration Statement or amendment or supplement or 
any blue sky, NASD or other filing, all financial and other records, 
pertinent corporate documents and properties of the Company, as they may 
reasonably request for the purpose, and cause the Company's officers, 
directors and employees to supply all information reasonably requested by any 
such representative, underwriter, attorney or accountant in connection with 
such Registration Statement; PROVIDED, HOWEVER, that the Holders shall first 
agree in writing with the Company that any information that is reasonably and 
in good faith designated by the Company in writing as confidential at the 
time of delivery of such information shall be kept confidential by the 
Holders and that the Holders will use reasonable efforts to cause its 
representatives and such other persons so to keep such information 
confidential, unless (i) disclosure of such information is required by court 
or administrative order or is necessary to respond to inquiries of regulatory 
authorities, (ii) disclosure of such information is required by law 
(including any disclosure requirements pursuant to Federal securities  laws 
in connection with the filing of any Registration Statement or the use of any 
prospectus referred to in this Registration Rights Agreement), (iii) such 
information becomes generally available to the  public, other than as a 
result of a disclosure or failure to safeguard by any such person, (iv) such 
information becomes available to any such  person from a source other than 
the Company and such source, to the knowledge of such persons, is not bound 
by a confidentiality agreement with the Company, or (v) such information was 
known to or is developed by such persons without reference to such 
confidential information of the Company.


                                       4 
<PAGE>
     3.   UNDERWRITTEN DISTRIBUTION.  If the Holders intend to distribute the 
Registrable Securities covered by a Registration Statement by means of an 
underwriting, the Holders shall so advise the Company and, subject to the 
provisions of Section 7 hereof, within 30 days of the date thereof and 
without limiting the generality of the other provisions hereof, the Company 
will prepare and file such amendment or amendments to the Registration 
Statement and make such other filings as may be necessary or appropriate to 
effect any such underwritten distribution.

     4.   MULTIPLE HOLDERS.  Except as specifically provided herein, if there 
is more than one Holder, such Holders shall act with respect to their rights 
under this Agreement according to the vote of a majority-in-interest.

     5.   EXPENSES OF REGISTRATION.  All Registration Expenses incurred in 
connection with any registration, qualification or compliance pursuant to 
this Registration Rights Agreement shall be borne by the Company, and all 
Selling Expenses shall be borne by the Holders.

     6.   REGISTRATION PROCEDURES.  In the case of each registration effected 
by the Company pursuant to this Registration Rights Agreement, the Company 
will keep the Holders advised in writing as to initiation of each 
registration and as to the completion thereof.  At its expense, the Company 
will use its reasonable best efforts to:

          (a)  Keep such registration effective for the period ending (i) 
sixty (60) months after the Registration Statement is declared effective by 
the Commission; or (ii) when the Holders have completed the  distribution of 
the Registrable Securities described in the Registration Statement relating 
thereto, whichever first occurs; and

          (b)  Furnish such number of prospectuses and other documents 
incident thereto as the Holders from time to time may reasonably request.

     7.   SUSPENSION OF USE OF REGISTRATION STATEMENT.  The Holders agree 
that, upon receipt of any notice from the Company of (A) the happening of any 
event which makes any statements made in the Registration Statement(s) or 
related prospectus(es) filed pursuant to this Registration Rights Agreement, 
or any document incorporated or deemed to be incorporated therein by 
reference, untrue in any material respect or which requires the making of any 
changes in such Registration Statement(s) or prospectus(es) so that, in the 
case of such Registration Statement(s), it will not contain any untrue 
statement of a material fact or omit to state any material fact required to 
be stated therein or necessary to make the statements therein, in light of 
the circumstance under which they were made, not misleading or (B) that, in 
the judgment of the Company's Board of Directors, it is advisable to suspend 
use of the prospectus(es) for a discrete period of time due to pending 
corporate developments which are or may be material to the Company but have 
not been disclosed in the Registration Statement(s) or in relevant public 
filings with the SEC, or (C) the SEC has issued a stop order suspending the 
effectiveness of the Registration Statement(s), the Holders will forthwith 
discontinue disposition of such shares covered by such Registration 
Statement(s) or 


                                       5
<PAGE>
prospectus(es) until it is advised in writing by the Company that use of the 
applicable prospectus may be resumed, and has received copies of any 
additional or supplemented filings that are incorporated or deemed to be 
incorporated by reference in such prospectus(es).  The Company shall use all 
reasonable best efforts to insure that the use of the prospectus(es) may be 
resumed as soon as practicable, and in any event shall not be entitled to 
require the Holders to suspend use of the prospectus(es) for more than thirty 
(30) consecutive days on any one occasion, more than forty-five (45) 
consecutive days in the aggregate on two occasions which are not at least 
ninety (90) days apart or more than an aggregate of sixty (60) days in any 
twelve month period.

     8.   INDEMNIFICATION.

          (a)  COMPANY INDEMNITY.  The Company will indemnify each of the 
Holders, each of their respective officers, directors, trustees and partners, 
and each person controlling any Holder within the meaning of Section 15 of 
the Securities Act and the rules and regulations thereunder, with respect to 
which registration, qualification or compliance has been effected pursuant to 
this Registration Rights Agreement, and each underwriter, if any, and each 
person who controls, within the meaning of Section 15 of the Securities Act 
and the rules and regulations thereunder, any underwriter, against all 
claims, losses, damages and liabilities (or actions in respect thereof) 
arising out of or based on any untrue statement (or alleged untrue statement) 
of a material fact contained in any prospectus, offering circular or other 
document (including any related Registration Statement, notification or the 
like) incident to any such registration, qualification or compliance, or 
based on any omission (or alleged omission) to state therein a material fact 
required to be stated therein or necessary to make the statements therein not 
misleading, or any violation by the Company of the Securities Act or any 
state securities law or in either case, any rule or regulation thereunder 
applicable to the Company and relating to action or inaction required of the 
Company in connection with any such registration, qualification or 
compliance, and will reimburse each Holder, each of their respective 
officers, directors, trustees and partners, and each person controlling any 
Holder, each such underwriter and each person who controls any such 
underwriter, for any legal and any other expenses reasonably incurred in 
connection with investigating and defending any such claim, loss, damage, 
liability or action, provided that the Company will not be liable in any such 
case to the extent that any such claim, loss, damage, liability or expense 
arises out of or is based on any untrue statement or omission (or alleged 
untrue statement or omission) based upon written information furnished to the 
Company by the Holder or the underwriter and stated to be specifically for 
use therein. The indemnity contained in this Section 8(a) shall not apply to 
amounts paid by the Holders in settlement of any such loss, claim, damage, 
liability or action if such settlement if effected without the consent of the 
Company (which consent will not be unreasonably withheld).

          (b)  HOLDER INDEMNITY.  The Holders will, if Registrable Securities 
held by them are included in the securities as to which such registration, 
qualification or compliance is being effected, indemnify the Company, each of 
its directors, officers, partners, and each underwriter, if any, of the 
Company's securities covered by such a registration statement, each person 
who controls 


                                       6
<PAGE>
the Company or such underwriter within the meaning of Section 15 of the 
Securities Act and the rules and regulations thereunder (a "Control Person"), 
against all claims, losses, damages and liabilities (or actions in respect 
thereof) arising out of or based on any untrue statement (or alleged untrue 
statement) of a material fact contained in any such registration statement, 
prospectus, offering circular or other document, or any omission (or alleged 
omission) to state therein a material fact required to be stated therein or 
necessary to make the statement therein not misleading, and will reimburse 
the Company and its directors, officers and partners, underwriters or Control 
Persons for any legal or any other expenses reasonably incurred in connection 
with investigating or defending any such claim, loss, damage, liability or 
action, in each case to the extent, but only to the extent, that such untrue 
statement (or alleged untrue statement) or omission (or alleged omission) is 
made in such Registration Statement, prospectus, offering circular or other 
document in reliance upon and in conformity with written information 
furnished to the Company by the Holders and stated to be specifically for use 
therein; provided, however, that (i) the obligations of a Holder shall not 
apply to amounts paid in settlement of any such claims, losses, damages or 
liabilities if such settlement is effected without the consent of such Holder 
(which consent shall not be unreasonably withheld) and (ii) the obligation 
each selling Holder shall be limited to an amount equal to the proceeds to 
such Holder from the Registrable Securities sold in connection with such 
registration.

          (c)  PROCEDURE.  Each party entitled to indemnification under this 
Section 8 (the "Indemnified Party") shall give notice to the party required 
to provide indemnification (the "Indemnifying Party") promptly after such 
Indemnified Party has actual knowledge of any claims as to which indemnity 
may be sought, and shall permit the Indemnifying Party to assume the defense 
of any such claim in any obligation resulting therefrom, provided that 
counsel for the Indemnifying Party, who shall conduct the defense of such 
claim or any litigation resulting therefrom, shall be approved by the 
Indemnified Party (whose approval shall not be unreasonably withheld), and 
the Indemnified Party may participate in such defense at such party's 
expense, and provided further that the Indemnifying Party shall pay such 
expense if representation of such Indemnified Party by the counsel retained 
by the Indemnifying Party would be inappropriate due  to actual or potential 
differing interests between the Indemnified Party and any other party 
represented by such counsel in such proceeding.  The failure of any 
Indemnified Party to give notice as provided herein shall not relieve the 
Indemnifying Party of its obligations under this Section 8 except to the 
extent that the Indemnifying Party is actually prejudiced by such failure to 
provide notice.  No Indemnifying Party, in the defense of any such claim or 
litigation, shall, except with the consent of each Indemnified Party, consent 
to entry of any judgment or enter into any settlement which does not include 
as an unconditional term thereof the giving by the claimant or plaintiff to 
such Indemnified Party of a release from all liability in respect to such 
claim or litigation.  Each Indemnified Party shall furnish such information 
regarding itself of the claim in question as an Indemnifying Party may 
reasonably request in writing and as shall be reasonably required in 
connection with the defense of such claim and litigation resulting therefrom.


                                       7

     9.   CONTRIBUTION.  If the indemnification provided for in Section 8 of 
this Registration Rights Agreement is held by a court of competent 
jurisdiction to be unavailable to the Indemnified Parties in respect of any 
losses, claims, damages or liabilities referred to herein, then each such 
Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall 
contribute to the amount paid or payable by such Indemnified Party as a 
result of such losses, claims, damages or liabilities (i) as between the 
Company on the one hand and the Indemnified Parties on the other, in such 
proportion as is appropriate to reflect the relative benefits received by the 
Company on the one hand and the Indemnified Parties, as the case may be, on 
the other from the offering of the Registrable Securities, or (ii) if such 
allocation is not permitted by applicable law, in such proportion as is 
appropriate to reflect not only such relative benefits but also the relative 
fault of the Company on the one hand and of the Indemnified Parties, as the 
case may be, on the other, in connection with the statements or omissions 
which resulted in such losses, claims, damages or liabilities, as well as any 
other relevant equitable considerations. In no event shall the obligation of 
any Indemnifying Party to contribute under this Section 9 exceed the amount 
that such Indemnifying Party would have been obligated to pay by way of 
indemnification if the Indemnification provided for under Section 8(a) or 
8(b) of this Registration Rights Agreement had been available under the 
circumstances. The Company and the Holders agree that it would not be just 
and equitable if contribution pursuant to this Section 9 were determined by 
pro rata allocation (even if the Indemnified Parties were treated as one 
entity for such purpose) or by any other method of allocation which does not 
take account of the equitable considerations referred to in the immediately 
preceding paragraphs. The amount paid or payable by an Indemnified Party as a 
result of the losses, claims, damages and liabilities referred to in the 
immediately preceding paragraphs shall be deemed to include, subject to the 
eliminations set forth above, any legal or other expenses reasonably incurred 
by such Indemnified Party in connection with investigating or defending any 
such action or claim. Notwithstanding the provisions of this Section 9, no 
Indemnified Party shall be required to contribute any amount in excess of the 
amount by which (i) in the case of the Holder, the net proceeds received by 
the Holder from the sale of Registrable Securities or (ii) in the case of an 
underwriter, the total price at which the Registrable Securities purchased by 
it and distributed to the public were offered to the public exceeds, in any 
such case, the amount of any damages that the Holder or underwriter has 
otherwise been required to pay by reason of such untrue or alleged untrue 
statement or omission or alleged omission.  No person guilty of fraudulent 
misrepresentation (within the meaning of Section 11(f) of the Securities Act) 
shall be entitled to contribution from any person who was not guilty of such 
fraudulent misrepresentation.

     10.  SURVIVAL.  The indemnity and contribution agreements contained in 
Sections 8 and 9 of this Registration Rights Agreement and the 
representations and warranties of the Company referred to in Section 2(b)(i) 
of this Registration Rights Agreement shall remain operative and in full 
force and effect regardless of (i) any termination of this Registration 
Rights Agreement or any underwriting agreement, (ii) any investigation made 
by or on behalf of the Company, and (iii) the consummation of the sale or 
successive resales of the Registrable Securities.


                                       8
<PAGE>
     11.  INFORMATION BY A HOLDER AND ANY UNDERWRITERS.  Each Holder and the
underwriters, if any, shall furnish to the Company, within twenty (20) business
days of the Company's request therefor, such information regarding such Holder
or underwriters, as the case may be, and the distribution proposed by such
Holder or underwriters, as the Company may reasonably request in writing as
shall be reasonably required in connection with any registration, qualification
or compliance referred to in this Registration Rights Agreement.

     12.  TRANSFER OR ASSIGNMENT OF REGISTRATION RIGHTS.  This Registration 
Rights Agreement, and the rights and obligations of a Holder hereunder, may 
be assigned by such Holder to any person or entity to which Shares are 
transferred by such Holder, and such transferee shall be deemed a "Holder" 
for purposes of this Registration Rights Agreement; provided that the 
transferee provides written notice of such assignment to the Company and 
agrees to be subject to all restrictions and obligations of this Registration 
Rights Agreement.

     13.  TERMINATION OF REGISTRATION RIGHTS.  The right of any Holder to 
request registration pursuant to Section 2 hereof shall terminate upon the 
earlier of (i) six (6) years from the date hereof or (ii) the date upon which 
all Registrable Securities have been sold to the public through a 
Registration Statement pursuant to Section 2 hereof or pursuant to Rule 144 
of the Securities Act.

     14.  MISCELLANEOUS.

          (a)  ENTIRE AGREEMENT.  This Registration Rights Agreement contains

subject matter hereof, and may not be amended, a provision hereunder waived,

Company and (ii) the holders of a majority of the Registrable Securities 
hereunder.  Any amendment, modification, termination or waiver effected in 
accordance with this Section 14(a) shall be binding upon each holder of any 
Registrable Securities then outstanding and each future holder of any such 
Registrable Securities of the Company.

          (b)  NOTICES.  Any notice or other communication given or permitted

                               GATEFIELD CORPORATION


TIMOTHY SAXE AND MICHAEL J. KUCHA hereby certify that:

The original Certificate of Incorporation was filed with the Secretary of

     TWO:    They are the duly elected and acting President and Secretary,

of Incorporation were duly adopted by the Corporation's Board of Directors in

Delaware.  This restatement of the Corporation's Certificate of Incorporation 
restates and integrates but does not further amend the provisions of the

provisions of this Restated Certificate of Incorporation.  The Certificate of 
Incorporation of GateField Corporation is hereby restated in accordance with 
Section 245 of the General Corporation Law of the State of Delaware to read 
as follows:
                                          
                                        I.
                                          

     The name of the corporation is GATEFIELD CORPORATION.
                                          
                                        II.

     The nature of the business or purposes to be conducted or promoted is:

     To engage in any lawful act or activity for which corporations may be

all classes of stock, of which, 65,000,000 shall be shares of Common Stock 
with a par value of $.10 per share and 2,000,000 shall be shares of series

<PAGE>

C.   The Board of Directors is authorized to issue series preferred stock 
from time to time in one or more series.  Each series shall be distinctively 
designated. Except as otherwise stated and expressed pursuant to the 
provisions of this Article, all series of series preferred stock shall rank 
equally and be identical in all respects.  The resolution or resolutions 
providing for the issue of series preferred stock shall specify the voting 
powers, if any, and the designations, preferences and relative, 
participating, optional or other special rights, and the qualifications, 
limitations, or restrictions thereof, of such series, including, but not 
limited to:

     1.   the number of shares to constitute the series and the distinctive 
designation thereof;

     2.   the voting powers, full or limited, or no voting powers;

     3.   the redemption price or prices, if any, and the terms and 
conditions on which shares of such series shall be redeemable at the option 
of the holders thereof or of the Corporation or on the occurrence of a 
specified event;

     4.   the rate of dividends payable on shares of such series; the 
conditions on which and the times when such dividends are payable; the 
preference to, or the relation to, the payment of the dividends on any other 
class or classes or any other series of stock, whether cumulative or 
non-cumulative, and, if cumulative, the dates from which dividends on shares 
of such series shall be cumulative.

     5.   the rights of shares of such series upon the liquidation, 
dissolution or winding up of, or upon any distribution of the assets of, the 
Corporation;

     6.   the rights, if any, of the holders of shares of such series or of 
the Corporation to convert such shares into, or exchange such shares for, 
shares of any other class or classes or of any other series of the same or 
any other class or classes of stock of the Corporation, or the conversion or 
exchange of shares of such series into such other shares upon the occurrence 
of a specified event; and the price or prices or the rates of exchange and 
the adjustments at which such shares shall be convertible or exchangeable; 
and any other terms and conditions of such conversion or exchange; and

     7.   the sinking fund requirements, if any, be applied to the purchase 
or redemption of shares of such series, including the amount of such fund or 
funds and the manner of application.

D.   The rights, preferences and privileges of the Series B Preferred Stock 
are as follows:

     1.   DIVIDENDS.

          a.   The holders of shares of Series B Preferred Stock shall be 
entitled to receive dividends of $0.137475 per share per annum (subject to 
appropriate adjustment in the event of any stock dividend, stock split, 
combination or other similar recapitalization affecting such shares), payable 
when and as declared by the Board of Directors of the Corporation.  The right 
to receive dividends on Series B Preferred Stock shall accrue and shall be 
cumulative from the date of issuance of each share of Series B Preferred 
Stock, whether or not declared.

          b.   The Corporation shall not declare or pay any distributions (as 
defined below) on shares of Common Stock until the holders of the Series B 
Preferred Stock then outstanding shall have first received a distribution at 
the rate specified in paragraph (a) of this Section 1.

          c.   For purposes of this Section 1, unless the context requires 
otherwise, "distribution" shall mean the transfer of cash or property without 
consideration, whether by way of 

                                       2.
<PAGE>

dividend or otherwise, payable other than in Common Stock or other securities 
of the Corporation, or the purchase or redemption of shares of the 
Corporation (other than repurchases of Common Stock held by employees or 
directors of, or consultants to, the Corporation upon termination of their 
employment or services pursuant to agreements providing for such repurchase 
at a price equal to the original issue price of such shares and other than 
redemptions in liquidation or dissolution of the Corporation) for cash or 
property, including any such transfer, purchase or redemption by a subsidiary 
of this Corporation.

     2.   LIQUIDATION, DISSOLUTION OR WINDING UP; CERTAIN MERGERS, 
CONSOLIDATIONS AND ASSET SALES.

          a.   In the event of any voluntary or involuntary liquidation, 
dissolution or winding up of the Corporation, including any insolvency or 
bankruptcy proceeding affecting the Company which is not dismissed within 
sixty (60) days of the filing thereof, the holders of shares of Series B 
Preferred Stock then outstanding shall be entitled to be paid out of the 
assets of the Corporation available for distribution to its stockholders, 
before any payment shall be made to the holders of Common Stock or any other 
class or series of stock ranking on liquidation junior to the Series B 
Preferred Stock (such Common Stock and other stock being collectively 
referred to as "Junior Stock") by reason of their ownership thereof, an 
amount equal to the greater of (i) $9.165 per share (subject to appropriate 
adjustment in the event of any stock dividend, stock split, combination or 
other similar recapitalization affecting such shares), plus any accrued and 
unpaid dividends, whether declared or not, or (ii) such amount per share as 
would have been payable had each such share been converted into Common Stock 
pursuant to Section 4 immediately prior to such liquidation, dissolution or 
winding up.  If upon any such liquidation, dissolution or winding up of the 
Corporation the remaining assets of the Corporation available for 
distribution to its stockholders shall be insufficient to pay the holders of 
shares of Series B Preferred Stock the full amount to which they shall be 
entitled, the holders of shares of Series B Preferred Stock and any class or 
series of stock ranking on liquidation on a parity with the Series B 
Preferred Stock shall share ratably in any distribution of the remaining 
assets and funds of the Corporation in proportion to the respective amounts 
which would otherwise be payable in respect of the shares held by them upon 
such distribution if all amounts payable on or with respect to such shares 
were paid in full.

          b.   After the payment of all preferential amounts required to be 
paid to the holders of Series B Preferred Stock and any other class or series 
of stock of the Corporation ranking on liquidation on a parity with the 
Series B Preferred Stock, upon the dissolution, liquidation or winding up of 
the Corporation, the holders of shares of Junior Stock then outstanding shall 
be entitled to receive the remaining assets and funds of the Corporation 
available for distribution to its stockholders.  

          c.   In the event of any merger or consolidation of the Corporation 
into or with another corporation (except one in which the holders of capital 
stock of the Corporation immediately prior to such merger or consolidation  
continue to hold at least  80% by voting power of the capital stock of the 
surviving corporation), or the sale of all or substantially all the assets of 
the Corporation, if the holders of at least 51% of the then outstanding 
shares of Series B Preferred Stock so elect by giving written notice thereof 
to the Corporation at least three days before the effective date of such 
event, then such merger, consolidation or asset sale shall be deemed to be a 
liquidation of the Corporation, and all consideration payable to the 
stockholders of the Corporation (in the case of a merger or consolidation), 
or all consideration payable to the Corporation, together with all other 
available assets of the Corporation (in the case of an asset sale), shall be 
distributed to the holders of capital stock of the Corporation in accordance 
with Subsections 2(a) and 2(b) above.  The Corporation shall promptly provide 
to the holders of shares of Series B Preferred Stock such information 
concerning the terms of such merger, consolidation or asset sale and the 
value of the assets of the Corporation as may reasonably be requested by the 
holders of Series B Preferred Stock in order to assist them in determining 
whether to make such an election.  If the holders of the Series B Preferred 
Stock make such an election, the Corporation shall use 

                                       3.
<PAGE>

its best efforts to amend the agreement or plan of merger or consolidation to 
adjust the rate at which the shares of capital stock of the Corporation are 
converted into or exchanged for cash, new securities or other property to 
give effect to such election.  The amount deemed distributed to the holders 
of Series B Preferred Stock upon any such merger or consolidation shall be 
the cash or the value of the property, rights or securities distributed to 
such holders by the acquiring person, firm or other entity.  The value of 
such property, rights or other securities shall be determined in good faith 
by the Board of Directors of the Corporation.  If no notice of the election 
permitted by this Subsection (c) is given, the provisions of Subsection 4(h) 
shall apply.

     3.   VOTING.

          a.   Each holder of outstanding shares of Series B Preferred Stock 
shall be entitled to the number of votes equal to the number of whole shares 
of Common Stock into which the shares of Series B Preferred Stock held by 
such holder are then convertible (as adjusted from time to time pursuant to 
Section 4 hereof), at each meeting of stockholders of the Corporation (and 
written actions of stockholders in lieu of meetings) with respect to any and 
all matters presented to the stockholders of the Corporation for their action 
or consideration.  Except as provided by law, by the provisions of Subsection 
3(b) or Subsection 3(c) below or by the provisions establishing any other 
series of Preferred Stock, holders of Series B Preferred Stock and of any 
other outstanding series of Preferred Stock shall vote together with the 
holders of Common Stock as a single class.  

          b.   The Corporation shall not amend, alter or repeal the 
preferences, special rights or other powers of the Series B Preferred Stock 
so as to affect adversely the Series B Preferred Stock, without the written 
consent or affirmative vote of the holders of a majority of the then 
outstanding shares of Series B Preferred Stock, given in writing or by vote 
at a meeting, consenting or voting (as the case may be) separately as a 
class.  For this purpose, without limiting the generality of the foregoing, 
the authorization of any shares of capital stock on a parity with, or with 
priority or preference over, the Series B Preferred Stock as to the right to 
receive either dividends or amounts distributable upon liquidation, 
dissolution or winding up of the Corporation shall be deemed to affect 
adversely the Series B Preferred Stock.

          c.   In addition to any other rights provided by law, so long as at 
least 500,000 shares of Series B Preferred Stock shall be outstanding 
(subject to appropriate adjustment in the event of any stock dividend, stock 
split, combination or other similar recapitalization affecting such shares), 
the Corporation shall not, without first obtaining the affirmative vote or 
written consent of the holders of not less than 50% of the then outstanding 
shares of Series B Preferred Stock: 

               (i)   Amend or repeal any provision of, or add any provision 
to, the Corporation's Certificate of Incorporation or By-Laws, if such action 
would adversely affect the preferences, rights, privileges or powers of, or 
the restrictions provided for the benefit of, Series B Preferred Stock; 

               (ii)  Authorize or issue any new or existing class or classes 
or series of capital stock, EXCLUDING, HOWEVER, shares of Common Stock issued 
(A) for a per share consideration greater than the Conversion Price (as 
defined in Section 4(a)), or (B) upon the exercise of options and warrants to 
acquire Common Stock which were outstanding prior to the Original Issue Date 
(as defined in Section 4(d)), other than the stock warrant to acquire Common 
Stock granted to Siemens Aktiengesellschaft ("Siemens") pursuant to Section 
5.2 of that certain License Agreement, dated as of October 22, 1997, between 
the Company and Siemens; 

               (iii) Authorize or issue shares of stock of any class or any 
bonds, debentures, 

                                       4.
<PAGE>

notes or other obligations convertible into or exchangeable for, or having 
rights to purchase, any shares of stock of the Corporation; 

               (iv)  Reclassify any Common Stock or any new or existing class 
or classes or series of capital stock; 

               (v)   Pay or declare any dividend or distribution on any 
shares of its capital stock (except dividends payable solely in shares of 
Common Stock), or apply any of its assets to the redemption, retirement, 
purchase or acquisition, directly or indirectly, through subsidiaries or 
otherwise, of any shares or its capital stock; or

               (vi)  Issue any options, warrants or other securities 
exercisable or exchangeable for or convertible into shares of stock of the 
Corporation, EXCLUDING, HOWEVER, options and warrants to purchase Common 
Stock for a per share consideration (including for this purpose the 
consideration paid for any such warrants plus the consideration, if any, paid 
upon the acquisition of such shares of Common Stock) of greater than the 
Conversion Price (as defined in Section 4(a)).

     4.   OPTIONAL CONVERSION.  The holders of the Series B Preferred Stock 
shall have conversion rights as follows (the "Conversion Rights"):

          a.   RIGHT TO CONVERT.  Each share of Series B Preferred Stock 
shall be convertible, at the option of the holder thereof, at any time and 
from time to time, and without the payment of additional consideration by the 
holder thereof, into such number of fully paid and nonassessable shares of 
Common Stock as is determined by dividing $4.5825 by the Conversion Price (as 
defined below) in effect at the time of conversion.  The "Conversion Price" 
shall initially be $1.00 per share or if the election is made to reduce the 
Conversion Price pursuant to the provisions of Section 5(a) hereof, $.75 per 
share.  Such initial Conversion Price, and the rate at which shares of Series 
B Preferred Stock may be converted into shares of Common Stock, shall be 
subject to adjustment as provided below.  In addition, any accrued and unpaid 
dividends in respect of shares of Series B Preferred Stock surrendered for 
conversion shall be convertible into such number of fully paid and 
nonassessable shares of Common Stock as is determined by dividing the 
aggregate dollar amount of such accrued and unpaid dividends by the 
Conversion Price.  

     In the event of a notice of redemption of any shares of Series B 
Preferred Stock pursuant to Section 5 hereof, the Conversion Rights of the 
shares designated for redemption shall terminate at the close of business on 
the fifth business day preceding the date fixed for redemption, unless the 
redemption price is not paid when due, in which case the Conversion Rights 
for such shares shall continue until such price is paid in full.  In the 
event of a liquidation of the Corporation, the Conversion Rights shall 
terminate at the close of business on the first full day preceding the date 
fixed for the payment of any amounts distributable on liquidation to the 
holders of Series B Preferred Stock.
                    
          b.   FRACTIONAL SHARES.  No fractional shares of Common Stock shall 
be issued upon conversion of the Series B Preferred Stock.  In lieu of any 
fractional shares to which the holder would otherwise be entitled, the 
Corporation shall pay cash equal to such fraction multiplied by the then 
effective Conversion Price.

          c.   MECHANICS OF CONVERSION.

               (i)  In order for a holder of Series B Preferred Stock to 
convert shares of Series B Preferred Stock into shares of Common Stock, such 
holder shall surrender the certificate or certificates for such shares of 
Series B Preferred Stock, at the office of the transfer agent for the Series 
B Preferred Stock (or at the principal office of the Corporation if the 
Corporation serves as its own transfer 

                                       5.
<PAGE>

agent), together with written notice that such holder elects to convert all 
or any number of the shares of the Series B Preferred Stock represented by 
such certificate or certificates.  Such notice shall state such holder's name 
or the names of the nominees in which such holder wishes the certificate or 
certificates for shares of Common Stock to be issued.  If required by the 
Corporation, certificates surrendered for conversion shall be endorsed or 
accompanied by a written instrument or instruments of transfer, in form 
satisfactory to the Corporation, duly executed by the registered holder or 
his or its attorney duly authorized in writing.  The date of receipt of such 
certificates and notice by the transfer agent (or by the Corporation if the 
Corporation serves as its own transfer agent) shall be the conversion date 
("Conversion Date").  The Corporation shall, as soon as practicable after the 
Conversion Date, issue and deliver at such office to such holder of Series B 
Preferred Stock, or to his or its nominees, a certificate or certificates for 
the number of shares of Common Stock to which such holder shall be entitled, 
together with cash in lieu of any fraction of a share.  

               (ii)  The Corporation shall at all times when the Series B 
Preferred Stock shall be outstanding, reserve and keep available out of its 
authorized but unissued stock, for the purpose of effecting the conversion of 
the Series B Preferred Stock, such number of its duly authorized shares of 
Common Stock as shall from time to time be sufficient to effect the 
conversion of all outstanding Series B Preferred Stock.  Before taking any 
action which would cause an adjustment reducing the Conversion Price below 
the then par value of the shares of Common Stock issuable upon conversion of 
the Series B Preferred Stock, the Corporation will take any corporate action 
which may, in the opinion of its counsel, be necessary in order that the 
Corporation may validly and legally issue fully paid and nonassessable shares 
of Common Stock at such adjusted Conversion Price.  

               (iii) Upon any such conversion, all accrued and unpaid 
dividends on the shares of Series B Preferred Stock surrendered for 
conversion shall be paid to the holders thereof.  

               (iv)  All shares of Series B Preferred Stock which shall have 
been surrendered for conversion as herein provided shall no longer be deemed 
to be outstanding and all rights with respect to such shares, including the 
rights, if any, to receive notices and to vote, shall immediately cease and 
terminate on the Conversion Date, except only the right of the holders 
thereof to receive shares of Common Stock in exchange therefor and payment of 
any dividends declared but unpaid thereon.  Any shares of Series B Preferred 
Stock so converted shall be retired and cancelled and shall not be reissued, 
and the Corporation (without the need for stockholder action) may from time 
to time take such appropriate action as may be necessary to reduce the 
authorized Series B Preferred Stock accordingly.  

               (v)   The Corporation shall pay any and all issue and other 
taxes that may be payable in respect of any issuance or delivery of shares of 
Common Stock upon conversion of shares of Series B Preferred Stock pursuant 
to this Section 4.  The Corporation shall not, however, be required to pay 
any tax which may be payable in respect of any transfer involved in the 
issuance and delivery of shares of Common Stock in a name other than that in 
which the shares of Series B Preferred Stock so converted were registered, 
and no such issuance or delivery shall be made unless and until the person or 
entity requesting such issuance has paid to the Corporation the amount of any 
such tax or has established, to the satisfaction of the Corporation, that 
such tax has been paid.

          d.   ADJUSTMENT FOR STOCK SPLITS AND COMBINATIONS.  If the 
Corporation shall at any time or from time to time after the date on which a 
share of Series B Preferred Stock was first issued ("Original Issue Date") 
effect a subdivision of the outstanding Common Stock, the Conversion Price 
then in effect immediately before that subdivision shall be proportionately 
decreased.  If the Corporation shall at any time or from time to time after 
the Original Issue Date combine the outstanding shares of Common Stock, the 
Conversion Price then in effect immediately before the combination shall be 
proportionately increased.  Any adjustment under this paragraph shall become 
effective at the close of business on the 

                                       6.
<PAGE>

date the subdivision or combination becomes effective.

          e.   ADJUSTMENT FOR CERTAIN DIVIDENDS AND DISTRIBUTIONS.  In the 
event the Corporation at any time, or from time to time after the Original 
Issue Date shall make or issue, or fix a record date for the determination of 
holders of Common Stock entitled to receive, a dividend or other distribution 
payable in additional shares of Common Stock, then and in each such event the 
Conversion Price for the Series B Preferred Stock then in effect shall be 
decreased as of the time of such issuance or, in the event such a record date 
shall have been fixed, as of the close of business on such record date, by 
multiplying the Conversion Price for the Series B Preferred Stock then in 
effect by a fraction:

               (i)   the numerator of which shall be the total number of 
shares of Common Stock issued and outstanding immediately prior to the time 
of such issuance or the close of business on such record date, and 

               (ii)  the denominator of which shall be the total number of 
shares of Common Stock issued and outstanding immediately prior to the time 
of such issuance or the close of business on such record date plus the number 
of shares of Common Stock issuable in payment of such dividend or 
distribution; provided, however, if such record date shall have been fixed 
and such dividend is not fully paid or if such distribution is not fully made 
on the date fixed therefor, the Conversion Price for the Series B Preferred 
Stock shall be recomputed accordingly as of the close of business on such 
record date and thereafter the Conversion Price for the Series B Preferred 
Stock shall be adjusted pursuant to this paragraph as of the time of actual 
payment of such dividends or distributions; and provided further, however, 
that no such adjustment shall be made if the holders of Series B Preferred 
Stock simultaneously receive a dividend or other distribution of shares of 
Common Stock in a number equal to the number of shares of Common Stock as 
they would have received if all outstanding shares of Series B Preferred 
Stock had been converted into Common Stock on the date of such event.

          f.   ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS.  In the 
event the Corporation at any time or from time to time after the Original 
Issue Date for the Series B Preferred Stock shall make or issue, or fix a 
record date for the determination of holders of Common Stock entitled to 
receive, a dividend or other distribution payable in securities of the 
Corporation other than shares of Common Stock, then and in each such event 
provision shall be made so that the holders of the Series B Preferred Stock 
shall receive upon conversion thereof in addition to the number of shares of 
Common Stock receivable thereupon, the amount of securities of the 
Corporation that they would have received had the Series B 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 conversion date, retained such securities receivable by them as aforesaid 
during such period, giving application to all adjustments called for during 
such period under this paragraph with respect to the rights of the holders of 
the Series B Preferred Stock; and provided further, however, that no such 
adjustment shall be made if the holders of Series B Preferred Stock 
simultaneously receive a dividend or other distribution of such securities in 
an amount equal to the amount of such securities as they would have received 
if all outstanding shares of Series B Preferred Stock had been converted into 
Common Stock on the date of such event.  

          g.   ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE OR SUBSTITUTION.  If 
the Common Stock issuable upon the conversion of the Series B Preferred Stock 
shall be changed into the same or a different number of shares of any class 
or classes of stock, whether by capital reorganization, reclassification, or 
otherwise (other than a subdivision or combination of shares or stock 
dividend provided for above, or a reorganization, merger, consolidation, or 
sale of assets provided for below), then and in each such event the holder of 
each such share of Series B Preferred Stock shall have the right thereafter 
to convert such share into the kind and amount of shares of stock and other 
securities and property receivable upon such reorganization, 
reclassification, or other change, by holders of the number 

                                       7.
<PAGE>

of shares of Common Stock into which such shares of Series B Preferred Stock 
might have been converted immediately prior to such reorganization, 
reclassification, or change, all subject to further adjustment as provided 
herein.  

          h.   ADJUSTMENT FOR MERGER OR REORGANIZATION, ETC.  In case of any 
consolidation or merger of the Corporation with or into another corporation 
or the sale of all or substantially all of the assets of the Corporation to 
another corporation (other than a consolidation, merger or sale which is 
covered by Subsection 2(c)), each share of Series B Preferred Stock shall 
thereafter be convertible (or shall be converted into a security which shall 
be convertible) into the kind and amount of shares of stock or other 
securities or property to which a holder of the number of shares of Common 
Stock of the Corporation deliverable upon conversion of such Series B 
Preferred Stock would have been entitled upon such consolidation, merger or 
sale; and, in such case, appropriate adjustment (as determined in good faith 
by the Board of Directors) shall be made in the application of the provisions 
in this Section 4 set forth with respect to the rights and interest 
thereafter of the holders of the Series B Preferred Stock, to the end that 
the provisions set forth in this Section 4 (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 of 
stock or other property thereafter deliverable upon the conversion of the 
Series B Preferred Stock.

          i.   NO IMPAIRMENT.  The Corporation will not, by amendment of its 
Certificate 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 the 
Corporation, but will at all times in good faith assist in the carrying out 
of all the provisions of this Section 4 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 B Preferred Stock against impairment.

          j.   CERTIFICATE AS TO ADJUSTMENTS.  Upon the occurrence of each 
adjustment or readjustment of the Conversion Price pursuant to this Section 
4, the Corporation at its expense shall promptly compute such adjustment or 
readjustment in accordance with the terms hereof and furnish to each holder 
of Series B Preferred Stock a certificate setting forth such adjustment or 
readjustment and showing in detail the facts upon which such adjustment or 
readjustment is based. The Corporation shall, upon the written request at any 
time of any holder of Series B Preferred Stock, furnish or cause to be 
furnished to such holder a similar certificate setting forth (i) such 
adjustments and readjustments, (ii) the Conversion Price then in effect, and 
(iii) the number of shares of Common Stock and the amount, if any, of other 
property which then would be received upon the conversion of Series B 
Preferred Stock.  

          k.   NOTICE OF RECORD DATE.  In the event: 

               (i)    that the Corporation declares a dividend (or any other 
distribution) on its Common Stock payable in Common Stock or other securities 
of the Corporation; 

               (ii)   that the Corporation subdivides or combines its 
outstanding shares of Common Stock; 

               (iii)  of any reclassification of the Common Stock of the 
Corporation (other than a subdivision or combination of its outstanding 
shares of Common Stock or a stock dividend or stock distribution thereon), or 
of any consolidation or merger of the Corporation into or with another 
corporation, or of the sale of all or substantially all of the assets of the 
Corporation; or 

               (iv)   of the involuntary or voluntary dissolution, 
liquidation or winding up of 

                                       8.
<PAGE>

the Corporation; then the Corporation shall cause to be filed at its 
principal office or at the office of the transfer agent of the Series B 
Preferred Stock, and shall cause to be mailed to the holders of the Series B 
Preferred Stock at their last addresses as shown on the records of the 
Corporation or such transfer agent, at least ten days prior to the date 
specified in (A) below or twenty days before the date specified in (B) below, 
a notice stating 

                    (a)  the record date of such dividend, distribution, 
subdivision or combination, 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, distribution, subdivision or combination are to be determined, or 

                    (b)  the date on which such reclassification, 
consolidation, merger, sale, dissolution, liquidation or winding up is 
expected to become effective, 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 or other property deliverable upon such 
reclassification, consolidation, merger, sale, dissolution or winding up.

     5.   REDEMPTION FOR FAILURE TO OBTAIN STOCKHOLDER APPROVAL AND EVENT OF 
NONCOMPLIANCE.

          a.   In the event that:

               (i)   the Corporation's stockholders do not, prior to December 
19, 1997, approve (x) an amendment to the Corporation's Certificate of 
Incorporation providing for the classification of the Board of Directors of 
the Corporation into three classes, with members of each class serving 
staggered three-year terms, and the election of one Director designated by 
the holders of Series B Preferred Stock as a Class II Director with an 
initial term of two years and one Director designated by the holders of 
Series B Preferred Stock as a Class III Director with an initial term of 
three years, (y) an amendment to the Company's Certificate of Incorporation 
providing for the increase in the number of shares of authorized Common Stock 
from 40,000,000 to 65,000,000 and (z) the sale to Idanta Partners Ltd., the 
Dunn Family Trust and the Perscilla Faily Trust of shares of Common Stock 
which, together with the shares of Series B Preferred Stock owned by such 
entities, represent more than twenty percent (20%) of the Company's 
outstanding Common Stock (on an as-converted basis), or

               (ii)  an Event of Noncompliance (as defined below) occurs, the 
holders of at least 51% of the then outstanding shares of Series B Preferred 
Stock may elect to either (A) cause the Company to redeem the shares of 
Series B Preferred Stock, in whole or in part, at a redemption price equal to 
$4.5825 per share plus accrued and unpaid dividends thereon (subject to 
adjustment for stock splits, stock dividends, combinations or similar 
recapitalizations affecting such shares) in cash for each share of Series B 
Preferred Stock then redeemed (the "Redemption Price") or (B) reduce the 
Conversion Price as to all shares of Series B Preferred Stock from $1.00 to 
$.75 per share.  If the election is made to reduce the Conversion Price, it 
shall be evidenced by a written notice delivered to the Company by such 
holders and such reduction shall automatically be effective on the date of 
delivery of such notice to the Company.

          b.   At least fifteen (15) days prior to the date fixed by holders 
electing to redeem their shares of Series B Preferred Stock ("Redeeming 
Holders"), for any redemption of Series B Preferred Stock (hereinafter the 
"Redemption Date"), the Redeeming Holders shall send the Corporation written 
notice that notifies the Corporation of their election to redeem such shares, 
specifying the Redemption Date and the number of shares to be redeemed and 
calling upon the Corporation to pay the Redemption Price (such notice 
hereinafter referred to as the "Redemption Notice"). On or prior to the 
Redemption Date, each Redeeming Holder shall surrender his or its certificate 
or certificates representing such shares 

                                       9.
<PAGE>

to the Corporation, and thereupon the Redemption Price of such shares shall 
be payable to the order of the person whose name appears on such certificate 
or certificates as the owner thereof and each surrendered certificate shall 
be cancelled.  In the event less than all the shares represented by any such 
certificate are redeemed, a new certificate shall be issued representing the 
unredeemed shares.  From and after the Redemption Date, unless there shall 
have been a default in payment of the Redemption Price, all rights of the 
holders of the Series B Preferred Stock designated for redemption in the 
Redemption Notice as holders of Series B Preferred Stock of the Corporation 
(except the right to receive the Redemption Price without interest upon 
surrender of their certificate or certificates) shall cease with respect to 
such shares, and such shares shall not thereafter be transferred on the books 
of the Corporation or be deemed to be outstanding for any purpose whatsoever.

          c.   "Event of Noncompliance", as used herein, means any of the
following:

               (i)    Any of the representations or warranties made by the 
Corporation in the Stock Purchase Agreement between the Corporation and the 
purchaser of the Series B Preferred Stock dated November 10, 1997 ("Stock 
Purchase Agreement"), or in any certificate or financial or other written 
statements of the Corporation furnished by or on behalf of the Corporation in 
connection with the execution and delivery of the Stock Purchase Agreement 
and the closings of the purchase of the securities contemplated thereby shall 
be false or (when taken together with other information furnished by or on 
behalf of the Corporation, including reports and/or filings made with the 
Securities and Exchange Commission) misleading in any material respect at the 
time made; or

               (ii)   The Corporation shall fail to perform or observe any 
covenant or agreement in the Stock Purchase Agreement, or any other covenant, 
term, provision, condition, agreement or obligations of the Corporation under 
the terms hereof and such failure shall continue uncured for a period of ten 
(10) business days after notice from any holder of Series B Preferred Stock 
of such failure; or (iii)  The Corporation shall (i) become insolvent; (ii) 
admit in writing its inability to pay its debts generally as they mature; 
(iii) make a general assignment for the benefit of creditors or commence 
proceedings for its dissolution; or (iv) apply for or consent to the 
appointment of a trustee, liquidator or receiver for it or for a substantial 
part of its property or business; or

               (iii)  A trustee, liquidator or receiver shall be appointed 
for the Corporation or for a substantial part of its property or business 
without its consent and shall not be discharged within sixty (60) days after 
such appointment; or

               (iv)   Any governmental agency or any court of competent 
jurisdiction at the instance of any governmental agency shall assume custody 
or control of the whole or any substantial portion of the properties or 
assets of the Corporation and shall not be dismissed within sixty (60) days 
thereafter; or 

               (v)    Any money judgment, writ or warrant of attachment, or 
similar process in excess of Five Hundred Thousand Dollars ($500,000) in the 
aggregate shall be entered or filed against the Corporation or any of its 
properties or other assets and shall remain unpaid, unvacated, unbonded and 
unstayed for a period of forty-five (45) days or in any event later than ten 
(10) days prior to the date of any proposed sale thereunder; or 

               (vi)   Bankruptcy, reorganization, insolvency or liquidation 
proceedings or other proceedings, or relief under any bankruptcy law or any 
law for the relief of debt shall be instituted by or against the Corporation 
and, if instituted against the Corporation, shall not be dismissed within 
sixty (60) days after such institution or the Corporation shall by any action 
or answer approve of, consent to, or acquiesce in any such proceedings or 
admit to any material allegations of, or default in answering a 

                                       10.
<PAGE>

petition filed in, any such proceeding; or

               (vii)  If prior to full conversion or redemption of the Series 
B Preferred Stock, trading in the shares of the Common Stock on the Nasdaq 
National Market shall be suspended for a period of five (5) consecutive 
trading days, other than as a result of the suspension of trading in 
securities in general, or if such shares are delisted and not relisted on the 
Nasdaq National Market within thirty (30) days thereafter; or 

               (viii) If the Corporation has not, if requested by the holders 
of Series B Preferred Stock to do so, in accordance with the Registration 
Rights Agreement between the Corporation and the holders of the Series B 
Preferred Stock, caused a registration statement relating to the resale of 
the Common Stock issuable upon conversion of the Series B Preferred Stock to 
be filed with the Securities and Exchange Commission and used its best 
efforts after such filing to cause said registration statement to be declared 
effective, as promptly as possible and in no event later than 60 days after 
request by such holders, by the Securities and Exchange Commission.  

     6.   REDEMPTION FOR FAILURE TO RESERVE SUFFICIENT SHARES OF COMMON STOCK.

          a.   In the event that at any time after October 31, 1999 all 
outstanding shares of Series B Preferred Stock cannot be fully converted into 
Common Stock at any time because the Corporation has failed to reserve or 
otherwise provide a sufficient number of shares of Common Stock to effect 
such conversion, the holders of at least 51% of the then outstanding shares 
of Series B Preferred Stock may elect to cause the Company to redeem the 
shares of Series B Preferred Stock, in whole or in part, at a redemption 
price per share (the "Section 6 Redemption Price") equal to the greater of 
(i) the Redemption Price and (ii) the result obtained by multiplying the Fair 
Market Value per share of Common Stock (as defined below) by the number of 
shares of Common Stock into which each share of Series B Preferred may then 
be converted.

          b.   The "Fair Market Value per share of Common Stock" shall be 
deemed to be the last reported sale price per share of Common Stock on a 
national securities exchange, the Nasdaq National Market, or another 
nationally recognized exchange or trading system on the date immediately 
preceding the date of delivery of the Section 6 Redemption Notice; or, if no 
such price is reported on such date, such price on the next preceding trading 
day on which such price is reported.  

          c.   Holders electing to redeem their shares of Series B Preferred 
Stock pursuant to this Section 6 (the "Section 6 Redeeming Holders"), shall 
send the Corporation written notice that notifies the Corporation of their 
election to redeem such shares in accordance with this Section 6, specifying 
the date (not less than ten days after the date of delivery of such notice) 
fixed by the Section 6 Redeeming Holders for the redemption of Series B 
Preferred Stock (hereinafter the "Section 6 Redemption Date"), and the number 
of shares to be redeemed and calling upon the Corporation to pay the Section 
6 Redemption Price (such notice hereinafter referred to as the "Section 6 
Redemption Notice").

          d.   On or prior to the Section 6 Redemption Date, each Section 6 
Redeeming Holder shall surrender his or its certificate or certificates 
representing such shares to the Corporation, and thereupon the Section 6 
Redemption Price of such shares shall be payable to the order of the person 
whose name appears on such certificate or certificates as the owner thereof 
and each surrendered certificate shall be cancelled.  In the event less than 
all the shares represented by any such certificate are redeemed, a new 
certificate shall be issued representing the unredeemed shares.  From and 
after the Section 6 Redemption Date, unless there shall have been a default 
in payment of the Section 6 Redemption Price, all rights of the holders of 
the Series B Preferred Stock designated for redemption in the Section 6 
Redemption Notice as holders of Series B Preferred Stock of the Corporation 
(except the 

                                       11.
<PAGE>

right to receive the Section 6 Redemption Price without interest upon 
surrender of their certificate or certificates) shall cease with respect to 
such shares, and such shares shall not thereafter be transferred on the books 
of the Corporation or be deemed to be outstanding for any purpose whatsoever.

E.   The rights, preferences and privileges of the Series C Preferred Stock 
are as follows:

     1.   DIVIDENDS.

          a.   The holders of shares of Series C Preferred Stock shall be 
entitled to receive dividends of $0.30 per share per annum (subject to 
appropriate adjustment in the event of any stock dividend, stock split, 
combination or other similar recapitalization affecting such shares), payable 
only when, as and if declared by the Board of Directors.  Such dividends 
shall not be cumulative and no right to such dividends shall accrue to the 
holders of shares of Series C Preferred Stock unless declared by the Board of 
Directors.

          b.   The Corporation shall not declare or pay any distributions (as 
defined below) on shares of Common Stock unless the Corporation has paid or 
set apart dividends with respect to the Series C Preferred Stock equal in the 
aggregate to not less than the total amount of dividends which would have 
been payable with respect to the shares of Series C Preferred Stock from 
their respective dates of issuance if dividends under paragraph (a) of this 
Section 1 were mandatory and cumulative.

          c.   For purposes of this Section 1, unless the context requires 
otherwise, "distribution" shall mean the transfer of cash or property without 
consideration, whether by way of dividend or otherwise, payable other than in 
Common Stock or other securities of the Corporation, or the purchase or 
redemption of shares of the Corporation (other than repurchases of Common 
Stock held by employees or directors of, or consultants to, the Corporation 
upon termination of their employment or services pursuant to agreements 
providing for such repurchase at a price equal to the original issue price of 
such shares and other than redemptions in liquidation or dissolution of the 
Corporation) for cash or property, including any such transfer, purchase or 
redemption by a subsidiary of this Corporation.

     2.   LIQUIDATION, DISSOLUTION OR WINDING UP; CERTAIN MERGERS, 
CONSOLIDATIONS AND ASSET SALES.

          a.   In the event of any voluntary or involuntary liquidation, 
dissolution or winding up of the Corporation, including any insolvency or 
bankruptcy proceeding affecting the Company which is not dismissed within 
sixty (60) days of the filing thereof, the holders of shares of Series C 
Preferred Stock then outstanding shall be entitled to be paid out of the 
assets of the Corporation available for distribution to its stockholders, 
after and subject to the payment in full of all amounts required to be 
distributed to the holders of Series B Convertible Preferred Stock (the 
"Series B Preferred Stock") and the holders of any other class or series of 
stock of the Corporation ranking on liquidation prior and in preference to 
the Series C Preferred Stock, but before any payment shall be made to the 
holders of Common Stock or any other class or series of stock ranking on 
liquidation junior to the Series C Preferred Stock (such Common Stock and 
other stock being collectively referred to as "Junior Stock") by reason of 
their ownership thereof, an amount equal to the greater of (i) $10.00 per 
share (subject to appropriate adjustment in the event of any stock dividend, 
stock split, combination or other similar recapitalization affecting such 
shares), plus any declared and unpaid dividends, or (ii) such amount per 
share as would have been payable had each such share been converted into 
Common Stock pursuant to Section 4 immediately prior to such liquidation, 
dissolution or winding up.  If upon any such liquidation, dissolution or 
winding up of the Corporation the remaining assets of the Corporation 
available for distribution to its stockholders shall be insufficient to pay 
the holders of shares of Series C Preferred Stock the full amount to which 
they shall be entitled, the holders of shares of Series C Preferred Stock and 

                                       12.
<PAGE>

any class or series of stock ranking on liquidation on a parity with the 
Series C Preferred Stock shall share ratably in any distribution of the 
remaining assets and funds of the Corporation in proportion to the respective 
amounts which would otherwise be payable in respect of the shares held by 
them upon such distribution if all amounts payable on or with respect to such 
shares were paid in full.

          b.   After the payment of all preferential amounts required to be 
paid to the holders of Series B Preferred Stock, the holders of any other 
class or series of stock of the Corporation ranking on liquidation on a 
parity with the Series B Preferred Stock, the holders of Series C Preferred 
Stock and the holders of any other class or series of stock of the 
Corporation ranking on liquidation on a parity with the Series C Preferred 
Stock, upon the dissolution, liquidation or winding up of the Corporation, 
the holders of shares of Junior Stock then outstanding shall be entitled to 
receive the remaining assets and funds of the Corporation available for 
distribution to its stockholders.  

          c.   In the event of any merger or consolidation of the Corporation 
into or with another corporation (except one in which the holders of capital 
stock of the Corporation immediately prior to such merger or consolidation 
continue to hold at least 80% by voting power of the capital stock of the 
surviving corporation), or the sale of all or substantially all the assets of 
the Corporation, if the holders of at least 51% of the then outstanding 
shares of Series B Preferred Stock so elect by giving written notice thereof 
to the Corporation at least three days before the effective date of such 
event, then such merger, consolidation or asset sale shall be deemed to be a 
liquidation of the Corporation, and all consideration payable to the 
stockholders of the Corporation (in the case of a merger or consolidation), 
or all consideration payable to the Corporation, together with all other 
available assets of the Corporation (in the case of an asset sale), shall be 
distributed to the holders of capital stock of the Corporation in accordance 
with Subsections 2(a) and 2(b) above.  The Corporation shall promptly provide 
to the holders of shares of Series C Preferred Stock such information 
concerning the terms of such merger, consolidation or asset sale and the 
value of the assets of the Corporation as may reasonably be requested by the 
holders of Series C Preferred Stock.  If the holders of the Series B 
Preferred Stock make such an election, the Corporation shall use its best 
efforts to amend the agreement or plan of merger or consolidation to adjust 
the rate at which the shares of capital stock of the Corporation are 
converted into or exchanged for cash, new securities or other property to 
give effect to such election.  The amount deemed distributed to the holders 
of Series C Preferred Stock upon any such merger or consolidation shall be 
the cash or the value of the property, rights or securities distributed to 
such holders by the acquiring person, firm or other entity.  The value of 
such property, rights or other securities shall be determined in good faith 
by the Board of Directors of the Corporation.  If no notice of the election 
permitted by this Subsection (c) is given, the provisions of Subsection 4(h) 
shall apply.

     3.   VOTING.

          a.   Each holder of outstanding shares of Series C Preferred Stock 
shall be entitled to the number of votes equal to the number of whole shares 
of Common Stock into which the shares of Series C Preferred Stock held by 
such holder are then convertible (as adjusted from time to time pursuant to 
Section 4 hereof), at each meeting of stockholders of the Corporation (and 
written actions of stockholders in lieu of meetings) with respect to any and 
all matters presented to the stockholders of the Corporation for their action 
or consideration.  Except as provided by law, by the provisions of Subsection 
3(b) or Subsection 3(c) below or by the provisions establishing any other 
series of Preferred Stock, holders of Series C Preferred Stock and of any 
other outstanding series of Preferred Stock shall vote together with the 
holders of Common Stock as a single class.

          b.   The Corporation shall not amend, alter or repeal the 
preferences, special rights or other powers of the Series C Preferred Stock 
so as to affect adversely the Series C Preferred Stock without the written 
consent or affirmative vote of the holders of a majority of the then 
outstanding shares 

                                       13.
<PAGE>

of Series C Preferred Stock given in writing or by vote at a meeting, 
consenting or voting (as the case may be) separately as a class.  For this 
purpose, without limiting the generality of the foregoing, the authorization 
of any shares of capital stock on a parity with, or with priority or 
preference over, the Series C Preferred Stock as to the right to receive 
either dividends or amounts distributable upon liquidation, dissolution or 
winding up of the Corporation shall be deemed to affect adversely the Series 
C Preferred Stock.

     4.   OPTIONAL CONVERSION.  The holders of the Series C Preferred Stock 
shall have conversion rights as follows (the "Conversion Rights"): 

          a.   RIGHT TO CONVERT.  Each share of Series C Preferred Stock 
shall be convertible, at the option of the holder thereof, at any time and 
from time to time, and without the payment of additional consideration by the 
holder thereof, into such number of fully paid and nonassessable shares of 
Common Stock as is determined by dividing $10.00 by the Conversion Price (as 
defined below) in effect at the time of conversion.  The "Conversion Price" 
shall initially be $1.50 per share.  Such initial Conversion Price, and the 
rate at which shares of Series C Preferred Stock may be converted into shares 
of Common Stock, shall be subject to adjustment as provided below.  In 
addition, any declared and unpaid dividends in respect of shares of Series C 
Preferred Stock surrendered for conversion shall be convertible into such 
number of fully paid and nonassessable shares of Common Stock as is 
determined by dividing the aggregate dollar amount of such declared and 
unpaid dividends by the Conversion Price.

     In the event of a notice of redemption of any shares of Series C 
Preferred Stock pursuant to Section 5 hereof, the Conversion Rights of the 
shares designated for redemption shall terminate at the close of business on 
the fifth business day preceding the date fixed for redemption, unless the 
redemption price is not paid when due, in which case the Conversion Rights 
for such shares shall continue until such price is paid in full.  In the 
event of a liquidation of the Corporation, the Conversion Rights shall 
terminate at the close of business on the first full day preceding the date 
fixed for the payment of any amounts distributable on liquidation to the 
holders of Series C Preferred Stock.

          b.   FRACTIONAL SHARES.  No fractional shares of Common Stock shall 
be issued upon conversion of the Series C Preferred Stock.  In lieu of any 
fractional shares to which the holder would otherwise be entitled, the 
Corporation shall pay cash equal to such fraction multiplied by the then 
effective Conversion Price.

          c.   MECHANICS OF CONVERSION.

               (i)   In order for a holder of Series C Preferred Stock to 
convert shares of Series C Preferred Stock into shares of Common Stock, such 
holder shall surrender the certificate or certificates for such shares of 
Series C Preferred Stock, at the office of the transfer agent for the Series 
C Preferred Stock (or at the principal office of the Corporation if the 
Corporation serves as its own transfer agent), together with written notice 
that such holder elects to convert all or any number of the shares of the 
Series C Preferred Stock represented by such certificate or certificates.  
Such notice shall state such holder's name or the names of the nominees in 
which such holder wishes the certificate or certificates for shares of Common 
Stock to be issued.  If required by the Corporation, certificates surrendered 
for conversion shall be endorsed or accompanied by a written instrument or 
instruments of transfer, in form satisfactory to the Corporation, duly 
executed by the registered holder or his or its attorney duly authorized in 
writing.  The date of receipt of such certificates and notice by the transfer 
agent (or by the Corporation if the Corporation serves as its own transfer 
agent) shall be the conversion date ("Conversion Date").  The Corporation 
shall, as soon as practicable after the Conversion Date, issue and deliver at 
such office to such holder of Series C Preferred Stock, or to his or its 
nominees, a certificate or certificates for the number of shares of Common 
Stock to which such holder shall be entitled, together with cash in lieu 

                                       14.
<PAGE>

of any fraction of a share.

               (ii)  The Corporation shall at all times when the Series C 
Preferred Stock shall be outstanding, reserve and keep available out of its 
authorized but unissued stock, for the purpose of effecting the conversion of 
the Series C Preferred Stock, such number of its duly authorized shares of 
Common Stock as shall from time to time be sufficient to effect the 
conversion of all outstanding Series C Preferred Stock.  Before taking any 
action which would cause an adjustment reducing the Conversion Price below 
the then par value of the shares of Common Stock issuable upon conversion of 
the Series C Preferred Stock, the Corporation will take any corporate action 
which may, in the opinion of its counsel, be necessary in order that the 
Corporation may validly and legally issue fully paid and nonassessable shares 
of Common Stock at such adjusted Conversion Price.

               (iii) Subject to Subsection 4(a) above, upon any such 
conversion, all declared and unpaid dividends on the shares of Series C 
Preferred Stock surrendered for conversion shall be paid to the holders 
thereof.  

               (iv)  All shares of Series C Preferred Stock which shall have 
been surrendered for conversion as herein provided shall no longer be deemed 
to be outstanding and all rights with respect to such shares, including the 
rights, if any, to receive notices and to vote, shall immediately cease and 
terminate on the Conversion Date, except only the right of the holders 
thereof to receive shares of Common Stock in exchange therefor and payment of 
any dividends declared but unpaid thereon.  Any shares of Series C Preferred 
Stock so converted shall be retired and canceled and shall not be reissued, 
and the Corporation (without the need for stockholder action) may from time 
to time take such appropriate action as may be necessary to reduce the 
authorized Series C Preferred Stock accordingly.

               (v)   The Corporation shall pay any and all issue and other 
taxes that may be payable in respect of any issuance or delivery of shares of 
Common Stock upon conversion of shares of Series C Preferred Stock pursuant 
to this Section 4.  The Corporation shall not, however, be required to pay 
any tax which may be payable in respect of any transfer involved in the 
issuance and delivery of shares of Common Stock in a name other than that in 
which the shares of Series C Preferred Stock so converted were registered, 
and no such issuance or delivery shall be made unless and until the person or 
entity requesting such issuance has paid to the Corporation the amount of any 
such tax or has established, to the satisfaction of the Corporation, that 
such tax has been paid.

          d.   ADJUSTMENT FOR STOCK SPLITS AND COMBINATIONS.  If the 
Corporation shall at any time or from time to time after the date on which a 
share of Series C Preferred Stock was first issued ("Original Issue Date") 
effect a subdivision of the outstanding Common Stock, the Conversion Price 
then in effect immediately before that subdivision shall be proportionately 
decreased.  If the Corporation shall at any time or from time to time after 
the Original Issue Date combine the outstanding shares of Common Stock, the 
Conversion Price then in effect immediately before the combination shall be 
proportionately increased.  Any adjustment under this paragraph shall become 
effective at the close of business on the date the subdivision or combination 
becomes effective.

          e.   ADJUSTMENT FOR CERTAIN DIVIDENDS AND DISTRIBUTIONS.  In the 
event the Corporation at any time, or from time to time after the Original 
Issue Date shall make or issue, or fix a record date for the determination of 
holders of Common Stock entitled to receive, a dividend or other distribution 
payable in additional shares of Common Stock, then and in each such event the 
Conversion Price for the Series C Preferred Stock then in effect shall be 
decreased as of the time of such issuance or, in the event such a record date 
shall have been fixed, as of the close of business on such record date, by 
multiplying the Conversion Price for the Series C Preferred Stock then in 
effect by a fraction:

                                       15.
<PAGE>

               (i)   the numerator of which shall be the total number of 
shares of Common Stock issued and outstanding immediately prior to the time 
of such issuance or the close of business on such record date, and  

               (ii)  the denominator of which shall be the total number of 
shares of Common Stock issued and outstanding immediately prior to the time 
of such issuance or the close of business on such record date plus the number 
of shares of Common Stock issuable in payment of such dividend or 
distribution; provided, however, if such record date shall have been fixed 
and such dividend is not fully paid or if such distribution is not fully made 
on the date fixed therefor, the Conversion Price for the Series C Preferred 
Stock shall be recomputed accordingly as of the close of business on such 
record date and thereafter the Conversion Price for the Series C Preferred 
Stock shall be adjusted pursuant to this paragraph as of the time of actual 
payment of such dividends or distributions; and provided further, however, 
that no such adjustment shall be made if the holders of Series C Preferred 
Stock simultaneously receive a dividend or other distribution of shares of 
Common Stock in a number equal to the number of shares of Common Stock as 
they would have received if all outstanding shares of Series C Preferred 
Stock had been converted into Common Stock on the date of such event.

          f.   ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS.  In the 
event the Corporation at any time or from time to time after the Original 
Issue Date for the Series C Preferred Stock shall make or issue, or fix a 
record date for the determination of holders of Common Stock entitled to 
receive, a dividend or other distribution payable in securities of the 
Corporation other than shares of Common Stock, then and in each such event 
provision shall be made so that the holders of the Series C Preferred Stock 
shall receive upon conversion thereof in addition to the number of shares of 
Common Stock receivable thereupon, the amount of securities of the 
Corporation that they would have received had the Series C 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 conversion date, retained such securities receivable by them as aforesaid 
during such period, giving application to all adjustments called for during 
such period under this paragraph with respect to the rights of the holders of 
the Series C Preferred Stock; and provided further, however, that no such 
adjustment shall be made if the holders of Series C Preferred Stock 
simultaneously receive a dividend or other distribution of such securities in 
an amount equal to the amount of such securities as they would have received 
if all outstanding shares of Series C Preferred Stock had been converted into 
Common Stock on the date of such event.

          g.   ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE OR SUBSTITUTION.  If 
the Common Stock issuable upon the conversion of the Series C Preferred Stock 
shall be changed into the same or a different number of shares of any class 
or classes of stock, whether by capital reorganization, reclassification, or 
otherwise (other than a subdivision or combination of shares or stock 
dividend provided for above, or a reorganization, merger, consolidation, or 
sale of assets provided for below or in Subsection 2(c) hereof), then and in 
each such event the holder of each such share of Series C Preferred Stock 
shall have the right thereafter to convert each such share into the kind and 
amount of shares of stock and other securities and property receivable upon 
such reorganization, reclassification, or other change, by holders of the 
number of shares of Common Stock into which such shares of Series C Preferred 
Stock might have been converted immediately prior to such reorganization, 
reclassification, or change, all subject to further adjustment as provided 
herein.

          h.   ADJUSTMENT FOR MERGER OR REORGANIZATION, ETC.  In case of any 
consolidation or merger of the Corporation with or into another corporation 
or the sale of all or substantially all of the assets of the Corporation to 
another corporation (other than a consolidation, merger or sale which is 
covered by Subsection 2(c)), each share of Series C Preferred Stock shall 
thereafter be convertible (or shall be converted into a security which shall 
be convertible) into the kind and amount of shares of stock or other 
securities or property to which a holder of the number of shares of Common 
Stock of the 

                                       16.
<PAGE>

Corporation deliverable upon conversion of such Series C Preferred Stock 
would have been entitled upon such consolidation, merger or sale; and, in 
such case, appropriate adjustment (as determined in good faith by the Board 
of Directors) shall be made in the application of the provisions in this 
Section 4 set forth with respect to the rights and interest thereafter of the 
holders of the Series C Preferred Stock, to the end that the provisions set 
forth in this Section 4 (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 of stock or other 
property thereafter deliverable upon the conversion of the Series C Preferred 
Stock.

          i.   NO IMPAIRMENT.  Without the consent of the holders of a 
majority of the Series C Preferred Stock the Corporation will not, by 
amendment of its Certificate 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 the Corporation, but will at all times in good faith assist in 
the carrying out of all the provisions of this Section 4 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 C Preferred Stock against 
impairment.  

          j.   CERTIFICATE AS TO ADJUSTMENTS.  Upon the occurrence of each 
adjustment or readjustment of the Conversion Price pursuant to this Section 
4, the Corporation at its expense shall promptly compute such adjustment or 
readjustment in accordance with the terms hereof and furnish to each holder 
of Series C Preferred Stock a certificate setting forth such adjustment or 
readjustment and showing in detail the facts upon which such adjustment or 
readjustment is based. The Corporation shall, upon the written request at any 
time of any holder of Series C Preferred Stock, furnish or cause to be 
furnished to such holder a similar certificate setting forth (i) such 
adjustments and readjustments, (ii) the Conversion Price then in effect, and 
(iii) the number of shares of Common Stock and the amount, if any, of other 
property which then would be received upon the conversion of Series C 
Preferred Stock.

          k.   NOTICE OF RECORD DATE.  In the event:

               (i)   that the Corporation declares a dividend (or any other 
distribution) on its Common Stock payable in Common Stock or other securities 
of the Corporation; 

               (ii)  that the Corporation subdivides or combines its 
outstanding shares of Common Stock;

               (iii) of any reclassification of the Common Stock of the  
Corporation (other than a subdivision or combination of its outstanding 
shares of Common Stock or a stock dividend or stock distribution thereon), or 
of any consolidation or merger of the Corporation into or with another 
corporation, or of the sale of all or substantially all of the assets of the 
Corporation; or

               (iv)  of the involuntary or voluntary dissolution, liquidation 
or winding up of the Corporation; 

               then the Corporation shall cause to be filed at its principal 
office or at the office of the transfer agent of the Series C Preferred 
Stock, and shall cause to be mailed to the holders of the Series C Preferred 
Stock at their last addresses as shown on the records of the Corporation or 
such transfer agent, at least ten days prior to the date specified in (A) 
below or twenty days before the date specified in (B) below, a notice stating

                    (a)  the record date of such dividend, distribution, 
subdivision or 

                                       17.
<PAGE>

combination, 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, 
distribution, subdivision or combination are to be determined, or

                    (b)  the date on which such reclassification, 
consolidation, merger, sale, dissolution, liquidation or winding up is 
expected to become effective, 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 or other property deliverable upon such 
reclassification, consolidation, merger, sale, dissolution or winding up.

     1.   REDEMPTION IN EVENT OF SERIES B PREFERRED STOCK REDEMPTION.

          (a)  In the event that holders of at least 51% of the Company's 
Series B Preferred stock elect to redeem any Series B Preferred Stock 
pursuant to Section 5 of the Certificate of Designations of the Series B 
Preferred Stock of the Company, the holders of at least 51% of the then 
outstanding shares of Series C Preferred Stock may elect to either cause the 
Company to redeem the shares of Series C Preferred Stock, in whole or in 
part, at a redemption price equal to $10.00 per share plus declared and 
unpaid dividends thereon (subject to adjustment for stock splits, stock 
dividends, combinations or similar recapitalizations affecting such shares) 
in cash for each share of Series C Preferred Stock then redeemed (the 
"Redemption Price"), PROVIDED, HOWEVER, that the holders of shares of Series 
C Preferred Stock shall not be entitled to cause the Company to redeem the 
shares of Series C Preferred Stock until the holders of shares of Series B 
Preferred Stock entitled to cause the Company to redeem the shares of Series 
B Preferred Stock and electing to so cause the Company to redeem the shares 
of Series B Preferred Stock have received their full redemption price for the 
shares they have elected to have redeemed.

          (b)  At least fifteen (15) days prior to the date fixed by holders 
electing to redeem their shares of Series C Preferred Stock ("Redeeming 
Holders"), for any redemption of Series C Preferred Stock (hereinafter the 
"Redemption Date"), the Redeeming Holders shall send the Corporation written 
notice that notifies the Corporation of their election to redeem such shares, 
specifying the Redemption Date and the number of shares to be redeemed and 
calling upon the Corporation to pay the Redemption Price (such notice 
hereinafter referred to as the "Redemption Notice").  On or prior to the 
Redemption Date, each Redeeming Holder shall surrender his or its certificate 
or certificates representing such shares to the Corporation, and thereupon 
the Redemption Price of such shares shall be payable to the order of the 
person whose name appears on such certificate or certificates as the owner 
thereof and each surrendered certificate shall be canceled.  In the event 
less than all the shares represented by any such certificate are redeemed, a 
new certificate shall be issued representing the unredeemed shares.  From and 
after the Redemption Date, unless there shall have been a default in payment 
of the Redemption Price, all rights of the holders of the Series C Preferred 
Stock designated for redemption in the Redemption Notice as holders of Series 
C Preferred Stock of the Corporation (except the right to receive the 
Redemption Price without interest upon surrender of their certificate or 
certificates) shall cease with respect to such shares, and such shares shall 
not thereafter be transferred on the books of the Corporation or be deemed to 
be outstanding for any purpose whatsoever.
                                          
                                       V.

     The Corporation is to have perpetual existence.


                                          
                                       VII.

     In furtherance and not in limitation of the powers conferred by statute, 
and by this Certificate of Incorporation, the Board of Directors is hereby 
expressly authorized to make, alter or repeal the By-Laws of the Corporation.

                                          
                                       VIII.
     
     Meetings of stockholders may be held within or without the State of 
Delaware, as the By-Laws may provide.  The books of the Corporation may be 
kept (subject to any provision contained in the statutes) outside the State 
of Delaware at such place or places as may be designated from time to time by 
the Board of Directors or in the By-Laws of the Corporation.  Elections of 
directors need not be by written ballot unless the By-Laws of the Corporation 
shall so provide.


                                        IX.
     
     The Corporation reserves the right to amend, alter, change or repeal any 
provision contained in this Certificate of Incorporation, in the manner now 
or hereafter prescribed by statute, and all rights conferred upon 
stockholders herein are granted subject to this reservation.

                                         X.

     No Director of the Corporation shall be personally liable to the 
Corporation or its stockholders for monetary damages for breach of fiduciary 
duty by such Director as a Director, provided, however, that this Article 10 
shall not eliminate or limit the liability of a Director to the extent 
provided by applicable law (i) for any breach of the Director's duty of 
loyalty to the Corporation or its stockholders, (ii) for acts or omissions 
not in good faith or which involve intentional misconduct or a knowing 
violation of law; (iii) under Section 174 of the General Corporation Law of 
the State of Delaware, or (iv) for any transaction from which the Director 
derived an improper personal benefit. No amendment to or repeal of this 
Article 10 shall apply to or have any effect on the liability or alleged 
liability of any Director of the Corporation for or with respect to any acts 
or omissions of such Director occurring prior to such amendment or repeal.

                                          
                                        XI.

     This Article 11 is inserted for the management of the business and for the
conduct of the affairs of the Corporation.


A.   NUMBER OF DIRECTORS.  The number of directors of the Corporation shall 
not be less than three.  The exact number of directors within the limitations 
specified in the preceding sentence shall be fixed from time to time pursuant 
to a resolution adopted by the Board of Directors.  

B.   CLASSES OF DIRECTORS.  The Board of Directors shall be and is divided 
into three classes: 

                                       19.
<PAGE>

Class I, Class II and Class III.  No one class shall have more than one 
director more than any other class.  If a fraction is contained in the 
quotient arrived at by dividing the authorized number of directors by three, 
then, if such fraction is one-third, the extra director shall be a member of 
Class I, and if such a fraction is two-thirds, one of the extra directors 
shall be a member of Class II, unless otherwise provided for from time to 
time by resolution adopted by a majority of the Board of Directors.

C.   TERMS OF OFFICE.  Each director shall serve for a term ending on the 
date of the third annual meeting following the annual meeting at which such 
director was elected; provided, that each initial director in Class I shall 
serve for a term ending on the date of the annual meeting next following the 
end of the Corporation's fiscal year ending December 31, 1997; each initial 
director in Class 11 shall serve for a term ending on the date of the annual 
meeting next following the end of the Corporation's fiscal year ending 
December 31, 1998; and each initial director in Class III shall serve for a 
term ending on the date of the annual meeting next following the fiscal year 
ending December 31, 1999; and provided further, that the term of each 
director shall continue until the election and qualification of his successor 
and shall be subject to his earlier death, resignation or removal.

D.   ALLOCATION OF DIRECTORS AMONG CLASSES IN THE EVENT OF INCREASES OR 
DECREASES IN THE NUMBER OF DIRECTORS.  In the event of any increase or 
decrease in the authorized number of directors, (i) each director then 
serving as such shall nevertheless continue as a director of the class of 
which he is a member until the expiration of his current term, subject to his 
earlier death, resignation or removal, and (ii) the newly created or 
eliminated directorships resulting from such increase or decrease shall be 
apportioned by the Board of Directors among the three classes of director in 
accordance with the provisions of Article XI(B) above.

E.   QUORUM; ACTION AT MEETING.  A majority of the total number of directors 
then in office shall constitute a quorum at all meetings of the Board of 
Directors.  In the event one or more of the directors shall be disqualified 
to vote at any meeting, then the required quorum shall be reduced by one for 
each such director so disqualified; PROVIDED, HOWEVER, that in no case shall 
less than one-third of the number of directors fixed pursuant to ArticleXI(A) 
above constitute a quorum. If at any meeting of the Board of Directors there 
shall be less than such a quorum, a majority of those present may adjourn the 
meeting from time to time.  Every act or decision done or made by a majority 
of the directors present at a meeting duly held at which a quorum is present 
shall be regarded as the act of the Board of Directors unless a greater 
number is required by law, by the By-Laws of the Corporation or by this 
Certificate of Incorporation.

F.   REMOVAL.  If and for so long as the Board of Directors is classified

can be manufactured using the Product Technology and the test program 
according to section 2.4 of this Agreement, GateField shall order and pay and 
Siemens shall deliver an agreed upon number of engineering lots of Wafers in 
accordance with Exhibits 5 and 6.  The verification is completed, when 
GateField demonstrates that Wafers out of engineering lots with parametric 
splits which are tested with the testprogramme according to section 2.4 of 
this Agreement are capable of reasonable and stable chip probe yields and 
Siemens agrees that such chip probe yields are reasonable in comparison to 
the probe yields of Siemens' own products manufactured with the Product 
Technology.

          2.3.3     For the purpose of qualification as specified in Exhibit 
4 GateField shall order and pay and Siemens shall deliver an agreed upon 
number of lots of Wafers in accordance with Exhibits 5 and 6.  Such Wafers

however, that if failures occur due to reasons, for which GateField is 
responsible, Siemens shall be paid 100% of the Wafer price as more specified 
in Exhibit 5.  GateField shall in accordance with an agreed schedule deliver 
to Siemens the documents and reports as defined in Exhibit 4.

          2.3.4     Prior to completion of the qualification, GateField may, 
in accordance with Exhibits 5 and 6, send Siemens a written request that 
Siemens provides Wafers out of "Risk Starts."  Within five business days of 
such Risk Start requests, Siemens will notify GateField whether Siemens 
accepts or refuses such Risk Start request(s).  If Siemens accepts such Risk 
Start, Siemens will provide these Wafers out of Risk Starts to GateField at 
the prices as more specified in Exhibit 5.  Notwithstanding anything to the 
contrary, if Siemens does not accept such Risk Start requests and GateField 
nevertheless wishes to start such Risk Wafers, GateField may send Siemens a 
binding purchase order according to Exhibit 6 for such Risk Start Wafers.


                                       3.

<PAGE>

If GateField sends Siemens such an order, Siemens will process these Wafers 
out of Risk Starts as required under this Agreement, and, once Sie1mens 
starts such Risk Start Wafers pursuant to such a purchase order, GateField 
shall be responsible to pay 100% of the Wafer price as described in Exhibit 5.

          2.3.5     During qualification, as specified in Exhibit 4, 
GateField may stop production of Wafers for any or all GateField Integrated 
Circuit Products by giving written notice to Siemens.  Siemens will stop 
production at suitable production steps following completion of the process 
step at which the Wafer reside at the time of Siemens' receipt of such 
notification.  Siemens shall invoice and GateField shall pay for all Wafers 
started prior to Siemens receiving such notice. Prices for such Wafers will 
be based on the stage of production of the Wafers as defined in Exhibit 5.

          2.3.6     Changes of a Product Technology or of the manufacturing 
processes of a Product Technology may be carried out in accordance with the 
Process Change Notification Procedure as defined in Exhibit 4.

          2.3.7     In case a re-qualification of the Product Technology 
according to this Section 2.3 is necessary Siemens shall provide GateField 
with the necessary Wafers for such re-qualification free of charge.

          2.3.8     The specifications and requirements specified in Exhibits 
4 can only be modified upon mutual written agreement between Siemens and 
GateField.

          2.3.9     If GateField determines that modifications to the 
specifications of Integrated Circuit Products are required, including 
modifications to mask tooling or a Product Technology, Siemens shall perform 
such modifications at GateField' cost which shall be fair and reasonable, 
provided that modifications to a Product Technology shall require Siemens' 
consent in advance.  The parties will negotiate adjustment to production 
price and delivery schedule in advance if price or delivery schedule are 
affected by such modifications. 

     2.4  TESTING CAPABILITY

          2.4.1     The testing of Wafers will be carried out by Siemens or 
any of its Subsidiaries or will be carried out for Siemens under contractual 
agreements. 

          2.4.2     Siemens may subcontract to a third party to test the 
Wafers in accordance with this Agreement for Siemens.  Prior to any 
subcontracting Siemens shall be obliged to conclude a written agreement with 
its subcontractor stipulating its obligations not less severe as laid down in 
this Agreement, especially with regard to nondisclosure and the use of the 
Product Information Package.  After such an agreement has been concluded 
between Siemens and its subcontractor Siemens 

               (a)  will notify GateField in writing of its intention to have 
the Wafers tested by the subcontractor and

               (b)  may provide the subcontractor with the necessary parts of 
the Product Information Package.

          2.4.3     For the purpose of testing the Wafers, GateField will 
provide for each Integrated Circuit Product a testprogramme and additional 
test information as more specified in Exhibit 3.

          2.4.4     The pricing of Wafer testing is based on hourly rates as 
described in Exhibit 5.  In case adaptions to the test programme become 
necessary Siemens will send a quotation to GateField concerning such 
adaptions.  In addition Siemens will send a quotation to GateField for the 
first set of probecard and loadboard (the later if different from 
standard-loadboards) for each Integrated Circuit Product.

          2.4.5     If Siemens wants to transfer the testing of Wafers to a 
location different from the location where the initial set up of the 
testprogramme was performed by GateField, Siemens shall be responsible for 
the transfer and setting up of the testing capability at the new location and 
shall provide correlation Wafers to GateField fee of charge.

          2.4.6     In case GateField is interested to perform the testing of 
Wafers of subcontract the testing of Wafers to a third party under its own 
responsibility, Siemens is willing to negotiate the terms and conditions of 
such option.

3.   PRODUCTION, FORECAST/ORDERING

     3.1  Upon written notice from GateField of successful completion of the 
qualification as described in Section 2 and having received a purchase order 
from GateField, Siemens or any of its Subsidiaries shall deliver Wafers 
according to the terms of this Agreement and as described in more detail in 
Exhibit 1, 4, 5, and 6.

     3.2  The business for each Integrated Circuit Product will be conducted 
in two phases.  In phase 1, forecasting, ordering as well as pricing will be 
based on Wafers.  In phase 2, the pricing will change to Good Dies, as more 
specified in Exhibit 5, ordering, delivery and forecasting will remain on 
Wafer base.

     3.3  As a basis for a mutual cooperation, both parties will define a 
model which extends the mutual commitment with respect to number of Wafers to 
be purchased by GateField and to be delivered by Siemens beyond the timeframe 
of individual purchase orders.  Such model shall be applied, if the volume 
ordered by GateField for all Integrated Circuit Products exceeds one thousand 
(1000) Wafers out per month for more than 3 consecutive months.

     3.4  GateField and Siemens agree on the forecast and ordering procedure 
in accordance with Exhibit 6.

     3.5  GateField may at any time add or substitute integrated circuits 
similar to the Integrated Circuit Products listed in Exhibit 1 to be 
manufactured and delivered under this Agreement with reasonable prior written 
notice.  A similar integrated circuit is one which is manufactured using the 
same Product Technology as Integrated Circuit Products, and in accordance 
with the same qualification plan as and with risk start quantities comparable 
to GateField Integrated Circuit Products currently manufactured under this 
Agreement.  Section 3.5 applies for such added or substituted Integrated 
Circuit Product only if engineering splits have proven, that such Integrated 
Circuit Product is capable of reasonable chip probe yields. 


                                       5.

<PAGE>


     3.6  In order to ensure traceability, processing and delivery of Wafers 
shall be performed lot by lot, unless agreed upon otherwise.  Production 
Wafer lots shall not have requirements for splitting neither for parameters 
nor for production stops.

     3.7  In the case of technical problems arising in the manufacturing of 
Wafers, especially with regard to yield, quality and reliability, Siemens 
shall inform GateField forthwith in writing.  Notwithstanding any right 
GateField may have, GateField will assist Siemens to identify the root cause 
of the above mentioned problems.

     3.8  Both parties shall immediately advise one another whenever they 
have reason to believe that Wafers may not conform to the applicable 
specifications.

     3.9  In case any technical problem, defect or malfunction should occur, 
which Siemens will be informed about, Siemens will immediately start 
investigations and supply a first substantiated answer or status report 
within ten (10) working-days after receipt of GateField' notification of such 
matter.  Such investigations may require GateField' support according to 
Section 3.7.

     3.10 GateField may stop production of Wafers for any or all GateField 
Integrated Circuit Products by giving written notice to Siemens.  Siemens 
will stop production at the next suitable process step following completion 
of the process step at which the Wafer reside at the time of Siemens' receipt 
of written notification.

     If such stop of production is due to any reason(s) not attributable to a 
failure by Siemens to fulfil its obligations under this Agreement; Siemens 
shall invoice and GateField shall pay for the Wafers as stated in Exhibit 5.

     If such stop of production is due to reasons attributable to a failure 
by Siemens to fulfill its obligations under this Agreement, only those wafers 
which meet the criteria applicable to production Wafers pursuant to Section 
2.3.3 and delivered and invoiced to GateField shall be paid for by GateField 
with 100% of the Wafer price as specified for Production Wafers in Exhibit 5.

     Notwithstanding anything to the contrary, and subject to the terms of 
this Section 3.10 with respect to payment, Siemens may, at its discretion and 
expense, elect to proceed with production as to which GateField has requested 
a stop by providing GateField advance written notice of the Wafers involved.

     3.11 Siemens shall cooperate with GateField in order to continuously 
improve the outgoing quality by agreed upon quality improvements programs.

     3.12 If Siemens wants to terminate the manufacturing of Wafers using a 
specific Product Technology, Siemens will notify GateField thereof in writing 
six (6) months prior to the planned termination of manufacturing.  In such 
case GateField may order and Siemens will deliver the remaining end of life 
demand for such Wafers according to the terms of this Agreement.

9.   INTELLECTUAL PROPERTY INDEMNITY

     9.1  It is GateField' responsibility to defend or to otherwise solve at 
GateField' expense any dispute arising from a claim that the Integrated 
Circuit Products infringe a third party's patent, trademark, copyright, mask 
work rights, trade secret or other intellectual properties (hereafter 
referred to as "Protective Rights") due to the GateField Product Information 
Package and incorporated in Integrated Circuit Products processed by Siemens.

     9.2  If a third party raises legally justifiable claims against 
GateField for infringement of Protective Rights by the Product Technology or 
the manufacturing processes of the Product Technology used by Siemens or its 
Subsidiaries to process the Wafers or the information provided according to 
Section 2.1.1, Siemens will, at its own cost, obtain for GateField a right to 
use the Wafers and sell the Integrated Circuit Products. If it should prove 
impossible to do so under financially acceptable conditions, Siemens may 
choose to modify the Product Technology or the manufacturing processes of the 
Product Technology used by Siemens or its Subsidiaries to process the Wafers 
or the information provided according to Section 2.1.1 so that it no longer 
infringes the Protective Rights, or will take back the Wafers and reimburse 
the price paid to Siemens.

     9.3  The obligations on Siemens identified under section 9.2 above will 
apply only if GateField advises Siemens without delay in writing of any 
claims for such infringement of Protective Rights, does not accept any such 
claim, and conducts any discussions, including out-of-court settlement, only 
in agreement with Siemens.

     9.4  The above liability shall be the sole and exclusive remedies 
between the parties with respect to intellectual property indemnity.

10.  EXPORT REGULATIONS

     10.1  GateField' Product Information Package as well as supplies to be 
performed under this Agreement are subject to governmental export 
regulations. Consequently, these obligations may be subject to the approval 
by the respective governmental authorities. 

     10.2  Both parities will comply with their respective governmental law 
and regulations.

11.  ASSIGNMENT

     11.1  Neither party shall delegate any obligations under this Agreement 
or assign this Agreement or any interest or rights hereunder without the 
prior written consent of the other, except incident to the sales or transfer 
of substantially all of such party's business.

     11.2  Siemens may have discharged its obligations covered under this 
Agreement by its Subsidiaries, provided however, that any assignment or 
delegation by Siemens to any of its Subsidiaries shall not relieve Siemens of 
ultimate responsibility for the performance of its obligations under this 
Agreement.
