Dear Stockholder:
   
  You are cordially invited to attend the Annual Meeting of Stockholders (the
"Paradigm Annual Meeting") of Paradigm Technology, Inc. ("Paradigm") which
will be held at 694 Tasman Drive, Milpitas, California 95035, on Tuesday,
August 4, 1998 at 9:00 a.m., local time.     
   
  At the Paradigm Annual Meeting, you will be asked to consider and vote upon
the issuance of shares of Paradigm common stock, par value $.01 per share
("Paradigm Common Stock"), in order to effect the proposed merger of Paradigm
Enterprises, Inc., a wholly-owned subsidiary of Paradigm ("Merger
Subsidiary"), with and into IXYS Corporation ("IXYS") pursuant to an Agreement
and Plan of Merger and Reorganization, dated as of March 6, 1998, as amended
(the "Merger Agreement"), among Paradigm, Merger Subsidiary and IXYS. In
addition, you will be asked to consider and vote upon an amendment to the
Restated Certificate of Incorporation to (i) effectuate a fifteen-for-one
reverse stock split, such that every fifteen shares of Paradigm Common Stock
shall be combined into one share (it should be noted that Paradigm
stockholders, at a Special Meeting of Stockholders held on May 1, 1998,
approved a ten-for-one reverse stock split such that every ten shares of
Paradigm Common Stock were combined into one share), (ii) increase the number
of authorized shares of Paradigm Common Stock to 40,000,000 and (iii) change
the name of Paradigm to IXYS Corporation. At the Paradigm Annual Meeting, you
will also be asked to (i) elect three directors to the Board of Directors of
Paradigm (the "Paradigm Board") to hold office until the next annual meeting
of stockholders or until their respective successors have been duly elected
and qualified, (ii) to approve the amendment to Paradigm's 1994 Stock Option
Plan (the "1994 Plan") to increase the aggregate number of shares of Paradigm
Common Stock authorized for issuance under such plan by 115,000 post-split
shares and to increase the number of shares of Paradigm Common Stock that can
be made subject to options in any fiscal year to 35,000 post-split shares, and
(iii) to ratify the appointment of PricewaterhouseCoopers LLP as independent
accountants of Paradigm for the fiscal year ending December 31, 1998. The
foregoing proposals are described more fully in the accompanying Joint Proxy
Statement/Prospectus, and a copy of the Merger Agreement is attached as Annex
A to the Joint Proxy Statement/Prospectus.     
 
  Pursuant to the Merger Agreement, Merger Subsidiary will be merged with and
into IXYS (the "Merger"), and the separate existence of Merger Subsidiary
shall cease. IXYS will continue as the surviving corporation in the Merger. At
that time, each outstanding share of common stock of IXYS, par value $.001 per
share ("IXYS Common Stock"), Series A Preferred Stock of IXYS, par value $.001
per share ("IXYS Series A Preferred Stock"), and Series B Preferred Stock of
IXYS, par value $.001 per share ("IXYS Series B Preferred Stock," and with the
IXYS Series A Preferred Stock, the "IXYS Preferred Stock") (the IXYS Common
Stock and the IXYS Preferred Stock, collectively, the "IXYS Capital Stock"),
will be converted into the right to receive a fraction of a share of Paradigm
Common Stock equal to the greater of two ratios (the "Exchange Ratio"). The
first ratio provides that, upon the Merger, the holders of IXYS Capital Stock
and options and warrants to purchase IXYS Common Stock will hold 95% of the
fully diluted capitalization of Paradigm and that the holders of capital
stock, options and warrants of Paradigm will hold 5% of the fully diluted
capitalization of Paradigm. (As used herein, fully diluted capitalization
means the sum of the number of shares of common stock, preferred stock,
warrants, options and other rights outstanding). The second ratio provides
that the value associated with the fully diluted capitalization of IXYS at the
time of the consummation of the Merger be at least $150 million, based upon
the average of the closing prices of Paradigm Common Stock for the ten trading
days ending (and including) the trading day two business days prior to the
date of the Paradigm Annual Meeting.
 
  Each outstanding option and warrant to purchase IXYS Common Stock will be
converted into a right to purchase that number of shares of Paradigm Common
Stock determined by multiplying the number of shares of IXYS Common Stock
subject thereto by the Exchange Ratio, at an exercise price equal to the
exercise price thereof divided by the Exchange Ratio.
<PAGE>
 
  Consummation of the proposed Merger is subject to, among other things,
approval by the holders of Paradigm Common Stock, IXYS Capital Stock and IXYS
Preferred Stock and upon satisfaction or waiver of the other conditions under
the Merger Agreement. The Merger will be consummated shortly after such
stockholder approvals are obtained and the other conditions to the Merger are
satisfied or waived. If the requisite approvals of the stockholders of
Paradigm and IXYS are received and the other conditions are satisfied or
waived, the Merger is expected to be consummated in August 1998.
 
  Approval of the reverse stock split, the increase in the number of shares of
Paradigm Common Stock authorized for issuance and the name change each
requires the affirmative vote of holders of a majority of the outstanding
shares of Paradigm Common Stock entitled to vote. Approval of the issuance of
Paradigm Common Stock in connection with the Merger, approval of the amendment
to the 1994 Plan and ratification of Paradigm's independent accountants each
requires the affirmative vote of holders of a majority of the outstanding
shares of Paradigm Common Stock present in person or by proxy at the Paradigm
Annual Meeting that vote on any such proposal. Director nominees receiving the
highest number of affirmative votes up to the number of directors to be
elected will be elected.
 
  Stockholders are urged to review carefully the information contained in the
Joint Proxy Statement/Prospectus prior to deciding how to vote their shares at
the Paradigm Annual Meeting.
 
  THE PARADIGM BOARD HAS UNANIMOUSLY DETERMINED THAT THE MERGER AGREEMENT AND
THE TRANSACTIONS CONTEMPLATED THEREBY ARE FAIR TO, AND IN THE BEST INTERESTS
OF, PARADIGM STOCKHOLDERS. ACCORDINGLY, THE PARADIGM BOARD HAS UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND THE MERGER, AND RECOMMENDS A VOTE FOR
APPROVAL OF THE ISSUANCE OF SHARES OF PARADIGM COMMON STOCK PURSUANT TO THE
MERGER AGREEMENT BY THE STOCKHOLDERS OF PARADIGM. THE PARADIGM BOARD ALSO
UNANIMOUSLY RECOMMENDS A VOTE FOR APPROVAL OF EACH OF THE OTHER PROPOSALS
DESCRIBED HEREIN AND FOR EACH OF THE NOMINEES FOR DIRECTOR.
 
  Whether or not you expect to attend the Paradigm Annual Meeting in person,
please complete, sign and promptly return the enclosed proxy card in the
enclosed postage-prepaid envelope to assure representation of your shares. You
may revoke your proxy at any time before it has been voted, and if you attend

Dear Stockholder:
   
  You are cordially invited to attend the Special Meeting of Stockholders (the
"IXYS Special Meeting") of IXYS Corporation ("IXYS") which will be held at
3540 Bassett Street, Santa Clara, California 95054, Tuesday, August 4, 1998,
at 9:00 a.m., local time.     
 
  At the IXYS Special Meeting, you will be asked to consider and vote upon the
approval and adoption of the Agreement and Plan of Merger and Reorganization,
dated as of March 6, 1998, as amended (the "Merger Agreement"), among Paradigm
Technology, Inc. ("Paradigm"), Paradigm Enterprises, Inc., a wholly-owned
subsidiary of Paradigm ("Merger Subsidiary"), and IXYS. The foregoing proposal
is described more fully in the accompanying Joint Proxy Statement/Prospectus,
and a copy of the Merger Agreement is attached as Annex A to the Joint Proxy
Statement/Prospectus.
 
  Pursuant to the Merger Agreement, Merger Subsidiary will be merged with and
into IXYS (the "Merger"), and the separate existence of Merger Subsidiary
shall cease. IXYS will continue as the surviving corporation in the Merger. At
that time, each outstanding share of common stock of IXYS, par value $.001 per
share ("IXYS Common Stock"), Series A Preferred Stock of IXYS, par value $.001
per share ("IXYS Series A Preferred Stock"), and Series B Preferred Stock of
IXYS, par value $.001 per share ("IXYS Series B Preferred Stock," and with the
IXYS Series A Preferred Stock, the "IXYS Preferred Stock") (the IXYS Common
Stock and the IXYS Preferred Stock, collectively, the "IXYS Capital Stock"),
will be converted into the right to receive a fraction of a share of common
stock of Paradigm, par value $.01 per share ("Paradigm Common Stock"), equal
to the greater of two ratios (the "Exchange Ratio"). The first ratio provides
that upon the Merger, the holders of IXYS Capital Stock and options and
warrants to purchase IXYS Common Stock will hold 95% of the fully diluted
capitalization of Paradigm and that the holders of capital stock, options and
warrants of Paradigm will hold 5% of the fully diluted capitalization of
Paradigm. (As used herein, fully diluted capitalization means the sum of the
number of shares of common stock, preferred stock, warrants, options and other
rights outstanding). The second ratio provides that the value associated with
the fully diluted capitalization of IXYS at the time of the consummation of
the Merger be at least $150 million, based upon the average of the closing
prices of Paradigm Common Stock for the ten trading days ending (and
including) the trading day two business days prior to the date of Paradigm's
meeting of stockholders.
 
  Each outstanding option and warrant to purchase IXYS Common Stock will be
converted into a right to purchase that number of shares of Paradigm Common
Stock determined by multiplying the number of shares of IXYS Common Stock
subject thereto by the Exchange Ratio, at an exercise price equal to the
exercise price thereof divided by the Exchange Ratio.
 
  Consummation of the proposed Merger is subject to, among other things,
approval by the holders of IXYS Capital Stock, IXYS Preferred Stock and
Paradigm Common Stock and upon satisfaction or waiver of the other conditions
under the Merger Agreement. The Merger will be consummated shortly after such
stockholder approvals are obtained and the other conditions to the Merger are
satisfied or waived. If the requisite approvals of the stockholders of
Paradigm and IXYS are received and the other conditions are satisfied or
waived, the Merger is expected to be consummated in August 1998.
 
  You will also be asked at the IXYS Special Meeting to consider and approve
the adoption of an amendment to the IXYS Certificate of Incorporation to
provide that the Merger does not constitute a liquidation under the IXYS
Certificate of Incorporation.
<PAGE>
 
  The approval and adoption of the Merger Agreement and approval of the Merger
and the approval of the amendment to the IXYS Certificate of Incorporation
each requires the affirmative vote of holders of a majority of the outstanding
shares of IXYS Capital Stock entitled to vote, voting together as a single
class, and the affirmative vote of holders of a majority of the outstanding
shares of IXYS Preferred Stock.
 
  Stockholders are urged to review carefully the information contained in the
Joint Proxy Statement/Prospectus prior to deciding how to vote their shares at
the IXYS Special Meeting.
 
  THE IXYS BOARD OF DIRECTORS HAS UNANIMOUSLY DETERMINED THAT THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY ARE FAIR TO, AND IN THE
BEST INTERESTS OF, IXYS STOCKHOLDERS. ACCORDINGLY, THE IXYS BOARD OF DIRECTORS
HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND APPROVED THE MERGER, AND
UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF IXYS VOTE FOR APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT AND APPROVAL OF THE MERGER. THE IXYS BOARD
ALSO UNANIMOUSLY RECOMMENDS A VOTE FOR APPROVAL OF THE AMENDMENT TO THE IXYS
CERTIFICATE OF INCORPORATION.
 
  Whether or not you expect to attend the IXYS Special Meeting in person,
please complete, sign and promptly return the enclosed proxy card in the
enclosed postage-prepaid envelope to assure representation of your shares. You
may revoke your proxy at any time before it has been voted, and if you attend

returned your proxy card. Your prompt cooperation will be greatly appreciated.

                         ANNUAL MEETING OF STOCKHOLDERS
                          OF PARADIGM TECHNOLOGY, INC.
 
                        SPECIAL MEETING OF STOCKHOLDERS
                              OF IXYS CORPORATION
 
                                   PROSPECTUS
                           PARADIGM TECHNOLOGY, INC.
                               38,041,470 SHARES
                     COMMON STOCK, PAR VALUE $.01 PER SHARE
 
  This Joint Proxy Statement/Prospectus (the "Joint Proxy
Statement/Prospectus") is being furnished to the stockholders of Paradigm
Technology, Inc., a Delaware corporation ("Paradigm"), in connection with the
solicitation of proxies by the Board of Directors of Paradigm (the "Paradigm
Board") for use at Paradigm's Annual Meeting of Stockholders or any
adjournments or postponements thereof (the "Paradigm Annual Meeting"). The
Paradigm Annual Meeting is being called to consider and vote upon a proposal to
approve the issuance of shares of common stock of Paradigm, par value $.01 per
share ("Paradigm Common Stock"), by Paradigm in connection with the Merger (as
defined below). The stockholders of Paradigm will also consider and vote upon
other proposals at the Paradigm Annual Meeting which are discussed in detail in
this Joint Proxy Statement/Prospectus.
 
  This Joint Proxy Statement/Prospectus is also being furnished to the
stockholders of IXYS Corporation, a Delaware corporation ("IXYS"), in
connection with the solicitation of proxies by the Board of Directors of IXYS
(the "IXYS Board") for use at IXYS' Special Meeting of Stockholders or any
adjournments or postponements thereof (the "IXYS Special Meeting"). The IXYS
Special Meeting is being called to consider and vote upon (i) a proposal to
adopt and approve the Agreement and Plan of Merger and Reorganization, dated as
of March 6, 1998, as amended, among Paradigm, Paradigm Enterprises, Inc., a
Delaware corporation and wholly-owned subsidiary of Paradigm ("Merger
Subsidiary"), and IXYS (the "Merger Agreement"), and to approve the merger of
Merger Subsidiary with and into IXYS (the "Merger"); and (ii) a proposal to
amend the IXYS Certificate of Incorporation to provide that the Merger does not
constitute a liquidation under the IXYS Certificate of Incorporation.
 
  Upon consummation of the Merger, IXYS will become a wholly-owned subsidiary
of Paradigm and each outstanding share of common stock of IXYS, par value $.001
per share ("IXYS Common Stock"), Series A Preferred Stock of IXYS, par value
$.001 per share ("IXYS Series A Preferred Stock"), and Series B Preferred Stock
of IXYS, par value $.001 per share ("IXYS Series B Preferred Stock," and
together with the IXYS Series A Preferred Stock, the "IXYS Preferred Stock,"
and together with the IXYS Common Stock, the "IXYS Capital Stock") (except for
any such shares held by IXYS or any subsidiary of IXYS (or held by IXYS as
treasury stock) and any such shares held by Paradigm or any subsidiary of
Paradigm), will be converted into the right to receive a fraction of a share of
Paradigm Common Stock equal to the greater of two ratios (the "Exchange Ratio"
as further defined herein). The first ratio provides that upon the Merger, the
holders of IXYS Capital Stock and options and warrants to purchase IXYS Common
Stock will hold 95% of the fully diluted capitalization of the Combined Company
(as hereinafter defined), and the holders of capital stock, options and
warrants of Paradigm will hold 5% of the fully diluted capitalization of the
 
                                                        (continued on next page)
 
  THE ABOVE MATTERS ARE DISCUSSED IN DETAIL IN THIS JOINT PROXY
STATEMENT/PROSPECTUS. STOCKHOLDERS OF PARADIGM AND IXYS ARE STRONGLY URGED TO
READ AND CONSIDER CAREFULLY THIS JOINT PROXY STATEMENT/ PROSPECTUS IN ITS
ENTIRETY, INCLUDING THE MATTERS REFERRED TO UNDER "RISK FACTORS" BEGINNING ON
PAGE 18.
 
  THE SHARES OF PARADIGM COMMON STOCK TO BE ISSUED IN CONNECTION WITH THE
MERGER HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE
COMMISSION (THE "COMMISSION") OR ANY STATE SECURITIES COMMISSION, NOR HAS THE
COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR
ADEQUACY OF THIS JOINT PROXY STATEMENT/PROSPECTUS. ANY REPRESENTATION TO THE
CONTRARY IS A CRIMINAL OFFENSE.
       
    The date of this Joint Proxy Statement/Prospectus is July 7, 1998.

Combined Company. (As used herein, fully diluted capitalization means the sum
of the number of shares of common stock, preferred stock, warrants, options
and other rights outstanding). The second ratio provides that the value
associated with the fully diluted capitalization of IXYS at the time of the
consummation of the Merger be at least $150 million, based upon the average of
the closing prices of Paradigm Common Stock for the ten trading days ending
(and including) the trading day two business days prior to the date of the
Paradigm Annual Meeting. Holders of IXYS Capital Stock will receive cash in
lieu of any fractional shares of Paradigm Common Stock to which such
stockholders would otherwise have been entitled. Paradigm may be referred to
as the "Combined Company" when the entity being described is Paradigm as it
shall exist following the Merger. As of June 16, 1998, the latest practicable
date prior to the distribution of this Joint Proxy Statement/Prospectus, the
exchange ratio used for purposes of this Joint Proxy Statement/Prospectus is
the second exchange ratio involving the valuation of IXYS' fully diluted
capitalization. At the Assumed Exchange Ratio, as hereinafter defined, the
exchange ratio would be 0.038876. Because the exchange ratio applied at the
Closing of the Merger depends on fluctuating market conditions, the
stockholders of IXYS and Paradigm will not know which exchange ratio will be
used until immediately prior to the time when the Certificate of Merger is
filed with the Delaware Secretary of State (the "Effective Time").
Consequently, the stockholders of IXYS and Paradigm will not know the exchange
ratio at the time of the respective stockholder meetings. However, following
the close of market on the day two business days before the date of the
stockholder meetings, the stockholders of IXYS may obtain information
regarding the exchange ratio, the minimum number of shares of Paradigm Common
Stock they will receive upon conversion of their IXYS Capital Stock and
procedures to amend their proxies by calling the following toll free phone
number: (800) 931-3323.     
 
  Upon the effectiveness of the Merger, each outstanding option to purchase
IXYS Common Stock (an "IXYS Option") will be converted into an option to
purchase that number of shares of Paradigm Common Stock determined by
multiplying the number of shares of IXYS Common Stock subject to such IXYS
Option immediately prior to the effective time of the Merger by the Exchange
Ratio, rounded down to the nearest whole share, at an exercise price equal to
the exercise price of such option at the time of the Merger divided by the
Exchange Ratio, rounded up to the nearest hundredth of a cent.
   
  In addition, after the effectiveness of the Merger, each outstanding warrant
to purchase IXYS Common Stock (an "IXYS Warrant") will be converted into a
warrant to purchase that number of shares of Paradigm Common Stock determined
by multiplying the number of shares of IXYS Common Stock subject to such IXYS
Warrant immediately prior to the effective time of the Merger by the Exchange
Ratio, rounded down to the nearest whole share, at an exercise price equal to
the exercise price of such warrant at the time of the Merger divided by the
Exchange Ratio, rounded up to the nearest hundredth of a cent. As a
consequence of the Merger, the current holders of IXYS Capital Stock, IXYS
Options and IXYS Warrants will hold approximately 97% of the fully diluted
capitalization of the Combined Company after the Merger, and the former
holders of Paradigm Common Stock, options and warrants will hold the remaining
3% of the fully diluted capitalization of the Combined Company.     
   
  The respective obligations of Paradigm, IXYS and Merger Subsidiary to
consummate the Merger and otherwise consummate the transactions contemplated
by the Merger Agreement are subject to the satisfaction or waiver (where
permissible) of certain conditions set forth in the Merger Agreement. These
conditions include, but are not limited to, the approval by Paradigm
stockholders of the issuance of Paradigm Common Stock in connection with the
Merger, a reverse stock split of Paradigm Common Stock, the increase of the
number of authorized shares of Paradigm Common Stock, the name change of
Paradigm, the approval and adoption by IXYS stockholders of the Merger
Agreement and approval of the Merger, and conversion of the outstanding 5%
Series A Convertible Redeemable Preferred Stock (the "Paradigm Series A
Preferred Stock"), 5% Series B Convertible Redeemable Preferred Stock (the
"Paradigm Series B Preferred Stock"), and 5% Series C Convertible Preferred
Stock (the "Paradigm Series C Preferred Stock") (collectively, the "Paradigm
Preferred Stock") into shares of Paradigm Common Stock. The Merger will be
consummated shortly after such stockholder approvals are obtained and the
other conditions to the consummation of the Merger are satisfied or waived. It
is currently anticipated that the Merger will be consummated in August 1998.
Under Delaware law, holders of IXYS Capital Stock who are entitled to vote at
the IXYS Special Meeting and who, prior to the IXYS Special Meeting, properly
demand appraisal rights and vote against or abstain from voting with respect
to the adoption and approval of the Merger Agreement and the approval of the
Merger, have the right to require the surviving corporation to purchase their
shares for "fair value," if the Merger is consummated. Stockholders of
Paradigm are not entitled to appraisal rights under Delaware law in connection
with the Merger.     
 
  All expenses related to Paradigm's solicitation of proxies, including the
cost of mailing this Joint Proxy Statement/Prospectus to the Paradigm
stockholders, will be borne by Paradigm. All expenses related to IXYS'
solicitation of proxies, including the cost of mailing this Joint Proxy
Statement/Prospectus to the IXYS stockholders, will be borne by IXYS.
 
  This Joint Proxy Statement/Prospectus also constitutes the Prospectus of
Paradigm with respect to the issuance of Paradigm Common Stock in connection
with the Merger.
   
  This Joint Proxy Statement/Prospectus and the accompanying forms of proxy
are first being mailed to stockholders of Paradigm and IXYS on or about July
9, 1998.     
 
  All information contained herein concerning Paradigm has been furnished by
Paradigm, and all information contained herein concerning IXYS has been
furnished by IXYS.

semiconductor market that require medium to high power semiconductors, with a
particular emphasis on "higher power" semiconductors, which are semiconductors
capable of processing greater than 500 watts of power.
 
  IXYS was initially incorporated in California in April 1983 and
reincorporated in Delaware in December 1995. IXYS' principal executive offices
are located at 3540 Bassett Street, Santa Clara, California 95054. Its
telephone number is (408) 982-0700.
 
PARADIGM ENTERPRISES, INC.
 
  Merger Subsidiary is a corporation recently organized as a wholly-owned
subsidiary of Paradigm for the purpose of effecting the Merger. Merger
Subsidiary has no material assets and has not engaged in any activities except
in connection with the Merger. Merger Subsidiary is a Delaware corporation, and
its principal executive offices are located at 694 Tasman Drive, Milpitas,
California 95035. Its telephone number is (408) 954-0500.
 
                            THE STOCKHOLDER MEETINGS
 
PARADIGM ANNUAL MEETING
   
  The Paradigm Annual Meeting will be held at the principal executive offices
of Paradigm located at 694 Tasman Drive, Milpitas, California 95035, on August
4, 1998 at 9:00 a.m. local time. The purpose of the Paradigm Annual Meeting is
to vote upon proposals to: (i) approve the issuance of Paradigm Common Stock in
    
                                       1
<PAGE>
 
   
connection with the Merger pursuant to the Merger Agreement (the "Issuance
Proposal"); (ii) to approve an amendment to Paradigm's Restated Certificate of
Incorporation (the "Paradigm Certificate of Incorporation") to effectuate a
fifteen-for-one reverse stock split, such that every fifteen shares shall be
combined into one share (the "Reverse Stock Split Proposal"); (iii) to approve
an amendment to the Paradigm Certificate of Incorporation to increase the
number of authorized shares of Paradigm Common Stock to 40,000,000 (the
"Increased Authorization Proposal"); (iv) to approve an amendment to the
Paradigm Certificate of Incorporation to change the name of Paradigm to IXYS
Corporation (the "Name Change Proposal"); (v) to elect three directors to the
Paradigm Board to hold office until the next annual meeting of stockholders or
until their respective successors have been duly elected and qualified (the
"Directors Proposal"); (vi) to approve the amendment to Paradigm's 1994 Stock
Option Plan (the "1994 Plan") to increase the aggregate number of shares of
Paradigm Common Stock authorized for issuance under such plan by 115,000 post-
split shares and to increase the number of shares of Paradigm Common Stock that
can be made subject to options in any fiscal year to 35,000 post-split shares
(the "Stock Plan Proposal"); and (vii) to ratify the appointment of
PricewaterhouseCoopers LLP as independent accountants of Paradigm for the
fiscal year ending December 31, 1998 (the "Ratification Proposal").     
 
  Only Paradigm stockholders of record at the close of business on June 19,
1998 (the "Paradigm Record Date") will be entitled to receive notice of and to
vote at the Paradigm Annual Meeting or any adjournment or postponement thereof.
As of the Paradigm Record Date, there were 262 stockholders of record holding
an aggregate of approximately 1,779,401 shares of Paradigm Common Stock. Each
share of Paradigm Common Stock entitles the holder thereof to one vote on any
matter that may properly come before the Paradigm Annual Meeting. The presence
in person or by properly executed proxy of holders of a majority of the issued
and outstanding shares of Paradigm Common Stock is necessary to constitute a
quorum at the Paradigm Annual Meeting. Approval of the Issuance Proposal and
the Stock Plan Proposal and the ratification of Paradigm's independent
accountants requires approval by the affirmative vote of a majority of the
shares present or represented by proxy and voting on the proposal. Approval of
the Reverse Stock Split Proposal, the Increased Authorization Proposal and the
Name Change Proposal requires the affirmative vote of the holders of a majority
of the outstanding shares of Paradigm Common Stock entitled to vote. Director
nominees receiving the highest number of affirmative votes up to the number of
directors to be elected will be elected.
 
  This Joint Proxy Statement/Prospectus and accompanying Notice of Annual
Meeting of Stockholders were mailed to all Paradigm's stockholders of record as
of the Paradigm Record Date and constitute notice of the Paradigm Annual
Meeting in conformity with the requirements of the Delaware General Corporation
Law (the "DGCL").
 
IXYS SPECIAL MEETING
   
  The IXYS Special Meeting will be held at the principal executive offices of
IXYS located at 3540 Bassett Street, Santa Clara, California 95054, on August
4, 1998, at 9:00 a.m., local time. The purpose of the IXYS Special Meeting is
to vote upon (i) a proposal to adopt and to approve the Merger Agreement and to
approve the Merger (the "Merger Proposal") and (ii) a proposal to amend the
IXYS Certificate of Incorporation to provide that the Merger does not
constitute a liquidation under the IXYS Certificate of Incorporation (the "IXYS
Certificate Proposal").     
 
  Only IXYS stockholders of record at the close of business on June 16, 1998
(the "IXYS Record Date") will be entitled to receive notice of and to vote at
the IXYS Special Meeting or any adjournment or postponement thereof. As of the
IXYS Record Date, there were 94 stockholders of record holding an aggregate of
approximately 72,211,873 shares of IXYS Common Stock, and 234 stockholders of
record holding an aggregate of approximately 111,409,363 shares of IXYS
Preferred Stock. Each share of IXYS Capital Stock entitles the holder thereof
to one vote on any matter that may properly come before the IXYS Special
Meeting. The presence in person or by properly executed proxy of holders of a
majority of the issued and outstanding shares of IXYS
 
                                       2
<PAGE>
 
Capital Stock is necessary to constitute a quorum at the IXYS Special Meeting.
The approval of the Merger Proposal and the IXYS Certificate Proposal each
requires the affirmative vote of a majority of the outstanding shares of IXYS
Capital Stock, entitled to vote, voting together as a single class, and the
affirmative vote of a majority of the outstanding shares of IXYS Preferred
Stock entitled to vote.
 
  Pursuant to that certain Voting Agreement (the "Voting Agreement"), dated as
of March 6, 1998, by and between Paradigm and Dr. Nathan Zommer, Chief
Executive Officer and Chairman of the Board of IXYS, Dr. Zommer has agreed
that, prior to the earlier of (i) the date upon which the Merger Agreement is
validly terminated or (ii) the date upon which the Merger becomes effective
(the "Expiration Date"), he will vote all of his IXYS Capital Stock,
representing approximately 30.90% of the shares of IXYS Capital Stock issued
and outstanding as of the IXYS Record Date, in favor of approval of the Merger
Proposal. In addition, Dr. Zommer has delivered to Paradigm an irrevocable
proxy with respect to such vote. See "The Merger Proposal and the Issuance
Proposal--Voting Agreement."
 
  As of the IXYS Record Date, the directors, executive officers and affiliates
of IXYS owned or had voting control over an aggregate of 155,853,329 shares of
IXYS Capital Stock, representing approximately 84.88% of the votes entitled to
be cast at the IXYS Special Meeting. Each of the directors, executive officers
and affiliates of IXYS has advised IXYS that he intends to vote or direct the
vote of all outstanding shares of IXYS Capital Stock over which he has voting
control in favor of the approval of the Merger Proposal.
 
  This Joint Proxy Statement/Prospectus and accompanying Notice of Special
Meeting of Stockholders were mailed to all IXYS stockholders of record as of
the IXYS Record Date and constitute notice of the IXYS Special Meeting in
conformity with the requirements of the DGCL.
 
                                   THE MERGER
 
GENERAL
 
  At the Effective Time, Merger Subsidiary will merge with and into IXYS, the
separate existence of Merger Subsidiary will cease and IXYS will continue as
the surviving corporation in the Merger (the "Surviving Corporation") and will
be a wholly-owned subsidiary of Paradigm. Paradigm's name shall be changed to
IXYS Corporation following the Merger. It is presently contemplated that the
Effective Time will occur as soon as practicable after the requisite approvals
of the stockholders of Paradigm and IXYS are obtained and other conditions to
the Merger set forth in the Merger Agreement are satisfied. It is currently
anticipated, assuming all requisite consents and approvals are received and all
conditions are satisfied or waived, that the Effective Time will occur in
August 1998. In addition, the Merger Agreement provides that, subject to the
terms and conditions thereof, at the Effective Time, the following will occur:
 
  Conversion of IXYS Capital Stock. Subject to the provisions contained in the
Merger Agreement relating to payment of cash in lieu of fractional shares, each
share of IXYS Capital Stock then outstanding will be converted into the right
to receive shares of Paradigm Common Stock based on the Exchange Ratio (as
defined below) (subject to adjustment as appropriate to reflect any stock
split, stock dividend, reverse stock split, reclassification, recapitalization
or other similar transaction involving the Paradigm Common Stock or the IXYS
Capital Stock between the date of the Merger Agreement and the effective time
of the Merger).
 
  The ratio for the exchange of each share of IXYS Capital Stock for Paradigm
Common Stock in the Merger (the "Exchange Ratio") shall be the greater of two
ratios. The two ratios will be evaluated, and the greater of the two ratios
will be determined and fixed, immediately prior to the Effective Time. The
first ratio (the "Percentage Formula Ratio") will be determined according to
the following formula:
 
                                   A = 19 X B
                                       ------
                                          C
 
                                       3
<PAGE>
 
 
where "A" is the Percentage Formula Ratio, "B" is the fully diluted
capitalization of Paradigm, immediately prior to the Effective Time and having
given effect to the reverse stock split contemplated by the Reverse Stock Split
Proposal (the "Reverse Stock Split"), expressed as the sum of (x) the number of
shares of Paradigm Common Stock outstanding, (y) the number of shares of
Paradigm Common Stock into which the outstanding Paradigm Preferred Stock
converts and (z) the aggregate number of shares of Paradigm Common Stock for
which outstanding warrants, options or other rights to acquire Paradigm Common
Stock are exercisable (the "Paradigm Fully Diluted Capitalization") and "C" is
the fully diluted capitalization of IXYS immediately prior to the Effective
Time, expressed as the sum of (A) the number of shares of IXYS Common Stock
outstanding, (B) the number of shares of IXYS Common Stock issuable upon
conversion of the outstanding shares of IXYS Preferred Stock and (C) the
aggregate number of shares of IXYS Common Stock for which outstanding warrants,
options or other rights to acquire IXYS Common Stock are exercisable (the "IXYS
Fully Diluted Capitalization").
   
  Assuming that the Paradigm Fully Diluted Capitalization is 223,128 and the
IXYS Fully Diluted Capitalization is 208,350,429, the Exchange Ratio as
calculated under the Percentage Formula Ratio is approximately 0.020348, which
is the result of 223,128 ("B" under the Percentage Formula Ratio) multiplied by
19 and divided by 208,350,429 ("C" under the Percentage Formula Ratio). If this
ratio is less than the ratio under the Valuation Formula, the Valuation Formula
Ratio would be used.     
 
  The second ratio (the "Valuation Formula Ratio") will be determined according
to the following formula:
 
                                D = $150,000,000
                                    ------------
                                      (E x C)
 
where "D" is the Valuation Formula Ratio, "E" is the average of the closing
sale prices of Paradigm Common Stock for the ten trading days ending (and
including) the trading day two business days prior to the date of the Paradigm
Annual Meeting (appropriately adjusted to reflect the Reverse Stock Split) and
"C" is the IXYS Fully Diluted Capitalization.
 
  For illustrative purposes only, the table below sets forth examples
estimating the Exchange Ratio for several alternative values of Paradigm Common
Stock:

- --------
  (1) Stock price based on fluctuating stock prices for illustrative
      purposes.
     
  (2) Based on the proposed 15-for-1 reverse stock split. Please note that
      where the initial stock price of Paradigm Common Stock was less than
      $3.311107 per share, the Valuation Formula Ratio was used because the
      value of the total number of shares the IXYS stockholders would receive
      under the Percentage Formula Ratio (in using that price) would have
      been less than $150 million. Conversely, if the initial stock price of
      Paradigm was more than $3.311107 per share, then the Percentage Formula
      Ratio was used. Therefore, all exchange ratio calculations made based
      on initial stock prices of Paradigm that were above $3.311107 were
      calculated using the Percentage Formula Ratio and all exchange ratio
      calculations made based on initial stock prices of Paradigm that were
      below $3.311107 were calculated using the Valuation Formula Ratio.
      Therefore, the "benchmark" stock price is $3.311107.     
   
  For each value of Paradigm Common Stock set forth in the foregoing table, the
table assumes that the outstanding shares of Paradigm Preferred Stock are
converted into Paradigm Common Stock in accordance with the terms of the
Paradigm Certificate of Incorporation based upon a five (5) day closing bid
price average equivalent to the value set forth for Paradigm Common Stock in
the table. The number of shares of Paradigm Common Stock issuable upon
conversion of the Paradigm Preferred Stock is subject to adjustment depending
on the date of the conversion thereof, and could be materially less or more
than such estimated amount depending on factors which cannot be predicted by
Paradigm, including, among other things, the future market price of Paradigm
Common Stock. Additionally, for each value of Paradigm Common Stock set forth
in the foregoing table, the table assumes that the ten (10) day average of
closing sale prices for Paradigm Common Stock to be used in the Valuation
Formula Ratio is equivalent to the value set forth in the table. Additionally,
the table assumes (i) a variable number of shares representing a Paradigm Fully
Diluted Capitalization which, as of June 16, 1998, was 223,128 shares and (ii)
an IXYS Fully Diluted Capitalization of 208,350,429 shares, based on securities
outstanding on June 16, 1998 (collectively, the "Exchange Ratio Assumptions").
Finally, the table assumes the Reverse Stock Split has taken place.
Consequently, at any given value for Paradigm Common Stock in the table, the
actual Exchange Ratio will vary from the number set forth in the table if the
averages of the closing sale prices of Paradigm Common Stock differ from one
another or the price of Paradigm Common Stock at the Effective Time or if the
fully diluted capitalization of either company at the Effective Time varies
from the amount assumed herein. See "The Merger Agreement--Merger
Consideration." Therefore, the actual value of the consideration and the number
of shares to be issued by Paradigm may differ from the value of the
consideration and the number of shares to be issued in accordance with the
Assumed Exchange Ratio. The number of shares to be issued in connection with
the Valuation Formula Ratio (if such exchange ratio is used) will not be
determined until immediately preceding the Annual Stockholder Meeting of
Paradigm and the number of shares to be issued in connection with the
Percentage Formula Ratio (if such exchange ratio is used) will not be
determined until immediately prior to the Effective Time. In both instances,
fluctuating market conditions relating to Paradigm's trading price are a factor
and may cause the final exchange ratio to be different from the Assumed
Exchange Ratio.     
 
  Fluctuations in Paradigm's Stock Price. The trading price of Paradigm's
Common Stock is subject to fluctuations. The trading price over the preceding
ninety (90) day period prior to May 1, 1998 ranged from a high of $0.781 to a
low of $0.25. During the period from May 4, 1998, the date Paradigm's ten-for-
one reverse stock split was effectuated, and June 16, 1998, Paradigm's Common
Stock traded from a high of $2.150 to a low of $0.875. Paradigm's stock price
is subject to continued fluctuations and may fluctuate drastically during the
period between stockholder approval and the Effective Time. There is always the
risk that Paradigm's stock price may drop significantly during this period,
which will have an impact on the Exchange Ratio. The Exchange Ratio will
increase for the benefit of the IXYS stockholders with any decline in
Paradigm's stock price.
 
  IXYS Stock Options; IXYS Warrants. At the Effective Time, each then
outstanding IXYS Option will be converted into an option to purchase Paradigm
Common Stock based on the Exchange Ratio. All rights with
 
                                       5
<PAGE>
 
respect to then outstanding IXYS Warrants shall be converted into and become
rights with respect to Paradigm Common Stock based on the Exchange Ratio. The
terms of the conversion of shares of IXYS Capital Stock into Paradigm Common
Stock and the conversion of IXYS Options and IXYS Warrants into options to
purchase shares of Paradigm are described in detail in "The Merger Agreement--
Stock Options; Warrants."
 
EFFECTIVE TIME OF THE MERGER; CLOSING DATE
 
  The Merger will become effective upon the filing of a Certificate of Merger
with the Secretary of State of the State of Delaware or at such later time as
may be specified in the Merger Agreement (the "Effective Time"). The
consummation of the transactions contemplated by the Merger Agreement will take
place on a date to be agreed upon by Paradigm and IXYS (the "Closing Date"),
which will be no later than the fifth business day after the satisfaction or
waiver of all of the conditions to closing set forth in the Merger Agreement.
Assuming that all of the conditions to the Merger are satisfied or waived, it
is anticipated that the Merger will be consummated in August 1998.
 
STOCK OWNERSHIP FOLLOWING THE MERGER
   
  Assuming the Exchange Ratio Assumptions, the occurrence of the Reverse Stock
Split and a price per share of Paradigm Common Stock of $18.519 (after the
occurrence of the Reverse Stock Split), an exchange ratio of 0.038876 (the
"Assumed Exchange Ratio") would result. At the Assumed Exchange Ratio and based
upon the foregoing assumptions, an aggregate of approximately 7,138,459 shares
of Common Stock of the Combined Company will be issued to holders of IXYS
Capital Stock and an additional approximately 961,372 shares of Common Stock of
the Combined Company will be issuable to holders of options and warrants
exercisable for IXYS Capital Stock. Based upon the number of shares of Paradigm
Common Stock issued and outstanding as of the Paradigm Record Date, and after
giving effect to the additional shares of Paradigm Common Stock that are
proposed to be issued in the Merger and assuming the Valuation Formula Ratio is
applicable, the former holders of IXYS Capital Stock would hold approximately
97.1% of the Combined Company's total issued and outstanding shares and the
former stockholders of Paradigm will hold the balance of the Combined Company's
total issued and outstanding shares, estimated to be approximately 2.9%. A
continued decline in the price of Paradigm's Common Stock will cause the
percentage of shares of the Combined Company to be held by former Paradigm
stockholders to decline. See "The Merger Agreement--Merger Consideration."     
 
PARADIGM'S REASONS FOR THE MERGER
 
  The Paradigm Board considered a wide variety of information and a number of
factors in connection with its evaluation of the proposed Merger and the Merger
Agreement, and determined that the Merger provides an opportunity that serves
the best interests of Paradigm and its stockholders. The Paradigm Board
believes that the Merger may result in a number of benefits to Paradigm and its
stockholders, including, among other benefits, the following:
 
  .  By combining IXYS' capability in power semiconductors and Paradigm's
     capability in high performance integrated circuits, Paradigm and IXYS
     together will have the potential to develop new products with higher
     value that each company would not separately be able to produce.
 
  .  The proposed Merger will help insulate Paradigm from adverse market
     conditions based on current market conditions for SRAMs, the intense
     competition, and lower than desired selling prices, by improving
     Paradigm's cost structure through consolidation and Paradigm's sales
     channels by adding IXYS' distribution channels in countries where
     Paradigm does not have a strong market presence.
 
  .  Paradigm will be in a better position to sell SRAM products to current
     IXYS customers who are not current Paradigm customers. This will
     therefore, provide Paradigm an opportunity to increase revenue.
 
  .  Paradigm's recent operating results, revenue level and current financial
     condition necessitates additional funding. The proposed Merger will
     provide such funding, which the Paradigm Board believes is a better
     alternative than additional equity financings.

RECOMMENDATION OF THE PARADIGM BOARD
 
  THE PARADIGM BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE
MERGER, AND RECOMMENDS A VOTE FOR APPROVAL OF THE ISSUANCE PROPOSAL BY THE
STOCKHOLDERS OF PARADIGM. THE PARADIGM BOARD ALSO UNANIMOUSLY RECOMMENDS A VOTE
FOR APPROVAL OF THE REVERSE STOCK SPLIT PROPOSAL, FOR APPROVAL OF THE INCREASED
AUTHORIZATION PROPOSAL, FOR APPROVAL OF THE NAME CHANGE PROPOSAL, FOR EACH
NOMINEE FOR DIRECTOR, FOR APPROVAL OF THE STOCK PLAN PROPOSAL, AND FOR
RATIFICATION OF THE INDEPENDENT ACCOUNTANTS.
 
OPINION OF FINANCIAL ADVISOR TO PARADIGM
 
  Alliant Partners LLP ("Alliant Partners ") delivered its opinion dated March
5, 1998 (the "Alliant Partners Opinion") to the Paradigm Board that, as of the
date of such opinion, the consideration to be paid to IXYS stockholders by
Paradigm was fair from a financial point of view to the Paradigm stockholders.
The full text of the Alliant Partners Opinion, which sets forth, among other
things, assumptions made, procedures followed, matters considered and
limitations on the scope of the review undertaken in connection with the
Alliant Partners Opinion, is attached hereto as Annex B and is incorporated
herein by reference. The Alliant Partners Opinion does not constitute a
recommendation as to how any holder of Paradigm Common Stock should vote at the
Paradigm Annual Meeting. Paradigm stockholders are urged to, and should, read
the Alliant Partners Opinion in its entirety. See "The Merger Proposal and the
Issuance Proposal--Opinion of Financial Advisor to Paradigm."
 
IXYS' REASONS FOR THE MERGER
 
  The IXYS Board considered a wide variety of information and a number of
factors in connection with its evaluation of the proposed Merger and the Merger
Agreement, and determined that the Merger provides an opportunity that serves
the best interests of IXYS and its stockholders. The IXYS Board believes that
the Merger may result in a number of benefits to IXYS and its stockholders,
including, among other benefits, the following:
 
  .  The combination of the technologies and product development resources of
     IXYS and Paradigm should enable IXYS to respond more effectively to the
     rapid technological change in, and continuing emergence of, power
     management control products; the technical know-how and design
     capabilities of the designers who design for Paradigm will allow IXYS to
     develop a new line of power management control products.
 
  .  In the Merger, IXYS stockholders will receive securities traded in an
     active trading market, the Nasdaq SmallCap Market, thereby permitting
     the stockholders to obtain liquidity for their investments, in contrast
     to the illiquid nature of their present holdings of IXYS Capital Stock.
 
  .  IXYS currently manufactures and designs various die sizes under 3 to 4
     micron design rules. Paradigm designs and markets die sizes at submicron
     design rules. IXYS believes that the Combined Company's ability to
     operate under a wide spectrum of process technologies, including
     submicron design rules not currently addressed by IXYS, is expected to
     enhance IXYS' ability to service its existing customer base as well as
     to expand into different customer bases.
 
  .  The Merger is expected to provide IXYS with an expanded customer base,
     and product development resources to support its current marketing,
     sales and distribution efforts; Paradigm's products are marketed,
     distributed and sold in applications and market segments not currently
     served by IXYS.
 
  .  The Merger will result in the Combined Company having an expanded base
     of intellectual property.
 
  See "The Merger Proposal and the Issuance Proposal--IXYS' Reasons for the
Merger."

RECOMMENDATION OF THE IXYS BOARD
 
  THE IXYS BOARD HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND THE MERGER,
AND RECOMMENDS A VOTE FOR ADOPTION AND APPROVAL OF THE MERGER PROPOSAL BY THE
STOCKHOLDERS OF IXYS. THE IXYS BOARD ALSO UNANIMOUSLY RECOMMENDS A VOTE FOR THE
IXYS CERTIFICATE PROPOSAL.
 
EXCHANGE OF IXYS STOCK CERTIFICATES
 
  As soon as reasonably practicable after the Effective Time, ChaseMellon
Shareholder Services, L.L.C. (the "Exchange Agent") will mail to the holders of
IXYS Capital Stock (i) a letter of transmittal (the "Letter of Transmittal")
with respect to the surrender of valid certificates representing shares of IXYS
Capital Stock (the "IXYS Stock Certificates") in exchange for certificates
representing Paradigm Common Stock and (ii) instructions for use of the Letter
of Transmittal. IXYS STOCKHOLDERS SHOULD NOT SURRENDER THEIR STOCK CERTIFICATES
FOR EXCHANGE UNTIL SUCH INSTRUCTIONS AND LETTER OF TRANSMITTAL ARE RECEIVED.
Although holders of IXYS Capital Stock are encouraged to surrender their stock
certificates for exchange promptly after the consummation of the Merger, there
is no deadline for holders of IXYS Capital Stock to surrender their stock
certificates in exchange for certificates representing the common stock of the
Combined Company. See "The Merger Agreement--Conversion of Shares; Procedures
for Exchange of Certificates."
 
NON-SOLICITATION
 
  Pursuant to the Merger Agreement, IXYS and Paradigm each have agreed not to
directly or indirectly take certain actions that may encourage an Acquisition
Proposal (as defined under "The Merger Agreement--Covenants"). However, IXYS
and Paradigm may each furnish information and enter into discussions or
negotiations in response to a bona fide, unsolicited Acquisition Proposal if
and only to the extent that the board of directors of the company receiving the
proposal determines in good faith that the Acquisition Proposal is financially
superior to the terms of the Merger, that financing for such Acquisition
Proposal is reasonably likely to be obtained, and that failure to take such
action would create a substantial risk of liability for breach of its fiduciary
obligations to IXYS' or Paradigm's respective stockholders under applicable
law. See "The Merger Agreement--Non-Solicitation."
 
MANAGEMENT AFTER THE MERGER
 
  At the Effective Time, all directors and executive officers of Paradigm shall
resign from their respective positions as director or executive officer (but
not as employee), except for Mr. Kochman who shall remain as a director of the
Combined Company. At the Effective Time, Dr. Zommer, Mr. Agbayani and Dr. Karg
will be appointed to the board of directors of the Combined Company. It is
currently expected that the executive officers of IXYS will serve after the
Effective Time as the executive officers of the Combined Company. See "The
Merger Agreement--Corporate Matters."
 
CONDITIONS TO THE MERGER
   
  The respective obligations of Paradigm, IXYS and Merger Subsidiary to
consummate the Merger are subject to the satisfaction or waiver of certain
conditions set forth in the Merger Agreement. These conditions include, among
others: (i) the approval by Paradigm's stockholders of the Issuance Proposal,
the fifteen-for-one reverse stock split, the Increased Authorization Proposal
and the Name Change Proposal, (ii) the conversion of all outstanding shares of
Paradigm Preferred Stock into Paradigm Common Stock (the "Paradigm Preferred

(the parties have already received notice of early termination of such     
 
                                       8
<PAGE>
 
waiting period from the Federal Trade Commission (the "FTC")), and (v) the

Common Stock to be issued in the Merger. See "The Merger Agreement--Conditions
to the Merger."
 
  In addition to the obligations set forth above, the obligations of Paradigm

or prior to the Closing, of the following conditions, among others: (i) the
representations and warranties of IXYS, when made and as of the Closing Date,
shall be accurate in all material respects; (ii) compliance with or performance
of all of the covenants or obligations required by the Merger Agreement to be
complied with and performed by IXYS at or prior to the Closing, in each case in
all material respects; (iii) receipt of a legal opinion of Cooley Godward LLP,
legal counsel to IXYS ("Cooley Godward"), (iv) receipt of all material consents
required to be obtained by IXYS; and (v) the absence of a material adverse
change with respect to IXYS. See "The Merger Agreement--Conditions to the
Merger."
 
  In addition to the obligations set forth above, the obligations of IXYS to
effect the Merger are subject to the satisfaction, at or prior to the Closing,
of the following conditions, among others: (i) the representations and
warranties of Paradigm and Merger Subsidiary, when made and as of the Closing
Date, shall be accurate in all material respects; (ii) compliance with or
performance of all of the covenants or obligations required by the Merger
Agreement to be complied with and performed by Paradigm at or prior to the

opinions; (iv) the absence of a material adverse change with respect to
Paradigm; (v) the trading of Paradigm Common Stock on the Nasdaq SmallCap
Market; (vi) limitations on appraisal rights available under Section 262 of the
DGCL to the IXYS stockholders; (vii) the absence of certain pending or
threatened legal proceedings; and (viii) receipt of all material consents
required to be obtained by Paradigm. See "The Merger Agreement--Conditions to
the Merger."
 
TERMINATION
 
  The Merger Agreement may be terminated at any time prior to the Effective
Time (i) by the mutual written consent of Paradigm and IXYS; (ii) by either
Paradigm or IXYS if the Merger shall not have been consummated by August 14,
1998; (iii) by either Paradigm or IXYS if a court or other governmental body
shall have issued a final and nonappealable order prohibiting the Merger; (iv)
by either Paradigm or IXYS if either such company's stockholders shall not have
approved the transactions contemplated by the Merger at the applicable
stockholders' meeting; (v) by IXYS if one or more of certain triggering events
relating to the implementation of the Merger by Paradigm or its acquisition by
a person other than IXYS occurs; (vi) by either Paradigm or IXYS if the other's
representations and warranties set forth in the Merger Agreement shall be or
shall have become materially inaccurate or if the other shall have breached any
covenant set forth in the Merger Agreement and if such inaccuracy or breach is
not curable. See "The Merger Agreement--Expenses and Termination Fees."
 
EXPENSES AND TERMINATION FEES
 
  Subject to certain conditions, if the Merger Agreement is terminated because
of the failure to obtain the necessary approvals of the stockholders of
Paradigm or the occurrence of a triggering event relating to the implementation
of the Merger by Paradigm or its acquisition by a person other than IXYS, and
Paradigm enters into another merger or similar transaction within six months
from the date of such termination, then upon consummation of such transaction,
Paradigm will be required to pay IXYS $500,000. If the Merger Agreement is
terminated because of the failure to obtain the necessary approvals of the
stockholders of IXYS, then IXYS will be required to pay Paradigm $500,000. See
"The Merger Agreement--Expenses and Termination Fees."
 
  In a separate agreement, Asea Brown Boveri, Inc. ("ABB Inc.") and Asea Brown
Boveri AG ("ABB AG" and together with ABB Inc., "ABB") agreed that if IXYS were
required to pay the termination fee described
 
                                       9
<PAGE>
 
above, ABB would reimburse IXYS in an amount not to exceed $500,000 so long as
(i) IXYS did not, on or prior to the date on which ABB was required to vote its
shares on the Merger Proposal, waive any rights IXYS may have not to consummate
the Merger because of Paradigm's failure to meet the condition relating to the
absence of any material adverse change with respect to Paradigm and (ii) Dr.
Zommer had voted all of the shares of IXYS Capital Stock owned by him in favor
of the Merger Proposal.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  Officers and Directors of Paradigm. Certain members of Paradigm's management
and the Paradigm Board may be deemed to have certain interests in the Merger
that are in addition to their interests as stockholders of Paradigm generally.
The interest of Paradigm's management and the Paradigm Board are as described
in"--Employment/Severance Arrangement" and "Other Information Regarding
Paradigm--Certain Relationships and Related Transactions." Other than as set
forth in "--Employment/Severance Arrangement," "Other Information Regarding
Paradigm--Certain Relationships and Related Transactions" and "Security
Ownership of Certain Beneficial Owners and Management of Paradigm" no other
benefits will be received by the Paradigm executive officers and directors. The
Paradigm Board was aware of these interests and considered them, among other
matters, in approving the Merger Agreement and the transactions contemplated
thereby. See "The Merger Proposal and the Issuance Proposal--Interests of
Certain Persons in the Merger."
 
  Indemnification and Insurance. The Merger Agreement provides that all rights
to indemnification existing in favor of the persons serving as directors and
officers of Paradigm as of the date of the Merger Agreement for acts or
omissions occurring prior to the Effective Time, as provided in Paradigm's
Certificate of Incorporation and Bylaws and in certain indemnification
agreements between Paradigm and such directors and officers, will survive the
Merger, and that Paradigm will cause the Surviving Corporation to perform its
obligations arising thereunder for at least six years from the Effective Time.
Subject to certain limitations, Paradigm has also agreed to cause the Combined
Company to maintain in effect for three years after the Effective Time the
policy of directors' and officers' liability insurance in existence at the date
of the Merger Agreement for the benefit of persons serving as directors and
officers of Paradigm as of such date. Such limitations include the fact that
the Combined Company shall not be required to maintain the directors' and
officers' liability insurance in existence as of the date of the Merger
Agreement if equivalent coverage is provided to such directors and officers
under another policy of directors' and officers' liability insurance. Further,
if  coverage is provided to such persons under another policy of officers' and
directors' liability insurances,  the Combined Company shall not be required to
expend in any one year an amount in excess of 150% of the annual premium
currently paid by Paradigm for such insurance, and if the annual premiums of
such insurance coverage exceed 150% of the annual premium currently paid by
Paradigm for such insurance, the Combined Company shall be obligated to obtain
a policy with the greatest coverage available for a cost not exceeding such
amount. See "The Merger Agreement--Indemnification and Insurance."
 
  Employment/Severance Arrangement. Each of Messrs. David Campbell and Richard
Morley (collectively the "Executives" and each an "Executive") have entered
into Executive Compensation Agreements with Paradigm, dated March 6, 1998 (the
"Executive Compensation Agreement"), which provide that if the Executive's
employment with the Combined Company is terminated without "cause" within six
months following the Effective Date, such Executive would be paid, in a single
lump sum payment, two months of salary at the rate in effect on the date of the
Executive Compensation Agreement. Messrs. Campbell and Morley are entitled to
two months of annual base salary for an aggregate of $10,834 and $25,000,
respectively, if they are terminated without "cause" within six months of the
Effective Date. See "The Merger Proposal and the Issuance Proposal--Interests
of Certain Persons in the Merger."
 
  Election as Director. Pursuant to the Merger Agreement, Mr. Kochman, who is
currently a director of Paradigm, will be nominated as a management nominee for
election to the Paradigm Board and shall remain as a director of the Combined
Company after the Merger. Mr. Kochman is also a managing partner and director
of
 
                                       10
<PAGE>
 
Alliant Partners, financial advisor to Paradigm. However, Mr. Kochman will not
derive any economic benefit from Alliant Partners' representation of Paradigm
in connection with the Merger. See "The Merger Proposal and the Issuance
Proposal--Interests of Certain Persons in the Merger."
 
  Officers and Directors of IXYS. Certain members of IXYS' management and Board
of Directors may be deemed to have certain interests in the Merger that are in
addition to their interests as stockholders of IXYS generally. The IXYS Board
was aware of these interests and considered them, among other matters, in
approving the Merger Agreement and the transactions contemplated thereby. At
the Effective Time, Dr. Zommer, Mr. Agbayani and Dr. Karg will be appointed to
the board of directors of the Combined Company. It is currently expected that
the executive officers of IXYS will serve after the Effective Time as the
executive officers of the Combined Company. In addition to the benefits
described below, the officers and directors of IXYS will benefit on the same
basis with respect to their stock and option holdings of IXYS as other holders
of IXYS Capital Stock and options exercisable for IXYS Common Stock. See
"Security Ownership of Certain Beneficial Owners and Management of IXYS."
 
  Indemnification and Insurance. The Merger Agreement provides that Paradigm
will cause the Surviving Corporation to perform its obligations under the IXYS
Certificate of Incorporation and Bylaws for at least six years from the
Effective Time. Subject to certain limitations, Paradigm has also agreed to
cause the Combined Company to maintain in effect for three years after the
Effective Time the policy of directors' and officers' liability insurance in
existence at the date of the Merger Agreement. Such limitations include the
fact that the Combined Company shall not be required to maintain the liability
insurance in existence as of the date of the Merger Agreement if equivalent
coverage is provided to such directors and officers under another policy of
officers' and directors' liability insurance. Further,  the Combined Company
shall not be required to expend in any one year an amount in excess of 150% of
the annual premium currently paid by Paradigm for such insurance, and if the
annual premiums of such insurance coverage exceed 150% of the annual premium
currently paid by Paradigm for such insurance, the Combined Company shall be
obligated to obtain a policy with the greatest coverage available for a cost
not exceeding such amount. See "The Merger Agreement--Indemnification and
Insurance."
 
  Registration Rights Agreement. In addition, as a condition to the
consummation of the Merger, two of IXYS' principal stockholders, Asea Brown
Boveri Inc. ("ABB Inc.") and Asea Brown Boveri AG ("ABB AG"), shall enter into
a Registration and Stockholder Rights Agreement (the "Registration Rights
Agreement") with Paradigm on or prior to the Effective Time. Dr. Rolf Karg is
an officer of ABB AG and a director of IXYS. Pursuant to the Registration
Rights Agreement, ABB AG and ABB, Inc. will be entitled to certain rights with
respect to registration of the Paradigm Common Stock they receive pursuant to
the Merger under the Securities Act. See "The Merger Proposal and the Issuance
Proposal--Interests of Certain Persons in the Merger."
 
REGULATORY MATTERS
 
  Paradigm and IXYS are not aware of any governmental or regulatory
requirements relating to the consummation of the Merger, other than compliance
with applicable federal and state securities laws and the HSR Act. On May 13,
1998, Paradigm and ABB filed a notification with the FTC and the Antitrust
Division of the Department of Justice (the "Antitrust Division") pursuant to
the HSR Act. They have subsequently received a notice of early termination of
such waiting period from the FTC. See "The Merger Proposal and the Issuance
Proposal--Regulatory Matters."
 
MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
  The Merger is expected to be a tax-free reorganization for federal income tax
purposes under Section 368(a) of the Internal Revenue Code of 1986, as amended
(the "Code"), so that no gain or loss will be recognized by the IXYS
stockholders on the exchange of IXYS Capital Stock for common stock of the
Combined Company,
 
                                       11
<PAGE>
 
except to the extent that IXYS stockholders receive cash in lieu of fractional
shares or in payment for shares as to which appraisal rights have been
perfected. Neither IXYS nor Paradigm will obtain a ruling from the Internal
Revenue Service as to the tax consequences of the Merger. As a condition to
IXYS' obligation to consummate the Merger, IXYS must receive an opinion at the
Effective Time from its legal counsel (or alternatively from Paradigm's legal
counsel) to the effect that the Merger will be treated as a tax-free
reorganization for federal income tax purposes. See "The Merger Proposal and
the Issuance Proposal--Material Federal Income Tax Consequences."
 
ANTICIPATED ACCOUNTING TREATMENT
 
  The Merger is intended to be accounted for as a "purchase" of Paradigm by
IXYS for financial reporting purposes in accordance with generally accepted
accounting principles ("GAAP"). Following the Merger, the Combined Company will
report on the basis of IXYS' historical financial statements and the fiscal
year end will be March 31. See "The Merger Proposal and the Issuance Proposal--
Anticipated Accounting Treatment."
 
APPRAISAL RIGHTS
 
  Under Delaware law, holders of IXYS Capital Stock who, prior to the IXYS
Special Meeting, properly demand appraisal and vote against or abstain from
voting with respect to the Merger Proposal, if entitled to vote at the IXYS
Special Meeting, have the right to require the Surviving Corporation to
purchase their shares for their "fair value," if the Merger is consummated. To
exercise such appraisal rights, such stockholders must comply with all
applicable procedural requirements. Stockholders of Paradigm are not entitled
to appraisal rights under Delaware law in connection with the Merger. See "The
Merger Proposal and the Issuance Proposal--Appraisal Rights" and Annex C to
this Joint Proxy Statement/Prospectus.

                                  RISK FACTORS
 
  The Merger and an investment in securities of Paradigm involve certain risks
and uncertainties, including risks relating to the integration of Paradigm and
IXYS, risks relating to the respective businesses of Paradigm and IXYS and
other risks and uncertainties discussed under "Risk Factors" and elsewhere in
this Joint Proxy Statement/Prospectus. See "Risk Factors."
 
                           MARKETS AND MARKET PRICES
   
  The following table sets forth the closing price per share of Paradigm Common
Stock as reported on the Nasdaq SmallCap Market under the symbol "PRDM" on (i)
March 6, 1998, the last trading day preceding public announcement of the
Merger, and (ii) July 2, 1998, the last trading day prior to the date of
printing of this Joint Proxy Statement/Prospectus. The equivalent IXYS per
share price at each specified date represents the closing price of a share of
Paradigm Common Stock on such date multiplied by an assumed exchange ratio
based on the Exchange Ratio Assumptions. See "The Merger Agreement--Merger
Consideration" and "--Stock Options; Warrants."

  Because the market price of Paradigm Common Stock is subject to fluctuation
and the Exchange Ratio is not fixed, the market value of the shares of Paradigm
Common Stock that holders of IXYS Capital Stock will receive in the Merger may
increase or decrease prior to the Effective Time. Stockholders of Paradigm and
IXYS are urged to obtain current market quotations for Paradigm Common Stock.
 
  There has been no public market for the IXYS Capital Stock.
 
                                DIVIDEND POLICY
 
  Neither Paradigm nor IXYS has declared or paid any cash dividends on any
series of its capital stock during any period for which information is provided
in this Joint Proxy Statement/Prospectus. Following the Merger, the Combined
Company does not intend to declare or pay any cash dividends in the foreseeable
future.

(1) The Paradigm historical book value is computed by dividing stockholders
    equity by the number of shares of Paradigm Common Stock outstanding at the
    end of the period (1,160,100 at December 31, 1997 and 1,779,401 at March
    31, 1998, respectively).
   
(2) Based upon the Assumed Exchange Ratio of 0.038876 of Paradigm Common Stock
    for each share of IXYS Capital Stock after giving effect to the Reverse
    Stock Split.     
(3) The IXYS historical book value is computed by dividing stockholders' equity
    by the number of shares of IXYS Common Stock outstanding at the end of the
    period. For IXYS, all shares of IXYS Preferred Stock are assumed to convert
    into IXYS Common Stock on a one-for-one basis.
   
(4) The IXYS pro forma equivalent per share amounts are calculated by
    multiplying the Paradigm combined pro forma per share amounts by the
    Assumed Exchange Ratio of 0.038876.     
 
Note: Comparative per share amounts could vary significantly as a result of
     changes in the Exchange Ratio (see pages 3 through 5 for additional
     discussion on the alternative ratios).

                                 RISK FACTORS
 
  This Joint Proxy Statement/Prospectus contains forward-looking statements
(including those set forth or referenced in "The Merger Proposal and the
Issuance Proposal--Background of the Merger," "--IXYS' Reasons for the
Merger," and "--Paradigm's Reasons for the Merger") that involve risks and
uncertainties. Paradigm's and IXYS' actual results may differ materially from
those anticipated in these forward-looking statements as a result of certain
risks and uncertainties, including risks relating to: (a) the integration of
Paradigm and IXYS; (b) the business of the Combined Company, including risks
relating to the impact of competitive products and pricing, the timely
development and market acceptance of new products and upgrades to existing
products, availability and cost of products from suppliers, industry wide
shifts in supply and demand for semiconductor products, or foreign currency
fluctuations, government actions and the overall condition of the
semiconductor industry; (c) the risk that the potential benefits of the Merger
might not be realized and the possibility that the Merger might adversely
affect the Combined Company's relationship with certain its respective
customers; and (d) other matters set forth in this section and elsewhere in
this Joint Proxy Statement/Prospectus. In addition to the other information in
this Joint Proxy Statement/Prospectus, the following factors should be
considered carefully (i) by IXYS stockholders in evaluating an investment in
the shares of Paradigm Common Stock offered by this Joint Proxy
Statement/Prospectus and (ii) by Paradigm stockholders in considering the
Issuance Proposal.
 
RISKS RELATING TO THE MERGER
   
  Dependence Upon IXYS Business, Operations and Management. This transaction
is a "reverse merger acquisition" in which the former stockholders, warrant
holders and optionees of IXYS will acquire a majority interest in the Combined
Company and will own, or have the right to acquire, approximately 97% of the
Combined Company. After the Merger, Paradigm stockholders, warrant holders and
optionees will own, or have the right to acquire, approximately 3% of the
Combined Company. In addition, following the Merger, the Combined Company's
business, operations and management will consist largely of the business,
operations and management of IXYS as existing prior to the Merger. Paradigm
stockholders should be aware that the Merger represents the investment of
substantially all of Paradigm's existing resources into a new and different
line of business, and that the Combined Company's future performance will be
largely dependent upon (and subject to the risks relating to) IXYS' business,
strategy, operations, management and personnel. Although Paradigm and IXYS
believe that the Combined Company will be able to realize value from
Paradigm's tangible and intangible assets after the Merger, there can be no
assurance that the Combined Company will be able to do so. In addition, there
can be no assurance that stockholders of Paradigm and IXYS would have achieved
greater returns on their investment if Paradigm and IXYS were to remain
independent companies.     
   
  Shares Eligible for Future Sale. In excess of 80% of Paradigm's currently
outstanding shares (as of June 16, 1998) are freely tradable (subject to
volume limitations applicable to affiliates). If the Merger is consummated at
an Assumed Exchange Ratio of 0.038876, after giving effect to the Reverse
Stock Split, Paradigm will issue to securityholders of IXYS approximately
7,138,459 shares of Paradigm Common Stock. Substantial sales of shares of
Paradigm Common Stock could occur after the Merger. Immediately upon
consummation of the Merger, all of the shares issuable in the Merger will be
freely-tradable (subject to volume limitations and other restrictions of Rules
144 and 145 under the Securities Act for persons who are affiliates of the
Combined Company following the Merger or who were affiliates of IXYS prior to
the Merger). Based on an Assumed Exchange Ratio of 0.038876, the number of
shares subject to IXYS Options and IXYS Warrants outstanding as of June 16,
1998 and Paradigm's intent to file a registration statement with respect to
the shares of Paradigm Common Stock underlying IXYS Options prior to the
Merger, approximately 961,372 additional shares could be sold upon the
exercise of IXYS Options and IXYS Warrants. See "The Merger Proposal and the
Issuance Proposal--Interests of Certain Persons" and "--Comparison of
Stockholders' Rights." In addition, prior to the consummation of the Merger,
Paradigm intends to provide for the acceleration of the vesting schedule for
all existing holders of Paradigm stock options. The number of freely tradeable
shares of Paradigm Common Stock will therefore increase based on the number of
option holders who choose to exercise their options. Future     
 
                                      18
<PAGE>
 
sales of a substantial number of shares of Paradigm Common Stock could
adversely affect or cause substantial fluctuations in the market price of
Paradigm Common Stock.
 
  Uncertainty Relating to Integration. The Merger involves the integration of
two companies that have previously operated independently. Such integration
will require significant effort from each company, including the coordination
of their research and development and sales and marketing efforts. There can
be no assurance that the Combined Company will integrate the respective
operations of Paradigm and IXYS without encountering difficulties or
experiencing the loss of IXYS or Paradigm personnel or that the benefits
expected from such integration will be realized. The diversion of the
attention of management and any difficulties encountered in the transition
process (including the interruption of, or a loss of momentum in, IXYS'
activities, problems associated with integration of management information and
reporting systems, and delays in implementation of consolidation plans) could
have an adverse impact on the Combined Company's ability to realize
anticipated synergies from the Merger.
 
  Incurrence of Significant Transaction Charges. Paradigm expects to incur
charges to operations currently estimated to be approximately $625,000. IXYS
expects to incur costs of approximately $800,000. These costs are to reflect
direct transaction costs, primarily for investment banking, legal and
accounting fees. This amount is a preliminary estimate and is therefore
subject to change. Additional unanticipated expenses may be incurred relating
to the integration of the businesses of Paradigm and IXYS. Currently, there
are no anticipated material costs in integrating IXYS and Paradigm. Although
it is expected that the elimination of duplicative expenses as well as other
efficiencies related to the integration of the business of the two companies
may offset additional expenses over time, there can be no assurance that such
net benefit will be achieved in the near term, or at all. There can be no
assurance that combining the business of Paradigm with the businesses of IXYS,
even if achieved in an efficient and effective manner, will result in combined
results of operations and financial condition superior to what would have been
achieved by each company independently.
 
  Rights of Holders of IXYS Capital Stock Following the Merger. Following the
Merger, holders of IXYS Capital Stock outstanding as of the Effective Time
will become holders of Paradigm Common Stock. Certain differences exist
between the rights of stockholders of IXYS under IXYS' Amended and Restated
Certificate of Incorporation and IXYS' Bylaws and the rights of stockholders
of Paradigm under Paradigm's Restated Certificate of Incorporation and
Paradigm's Bylaws. See "Comparison of Stockholders' Rights."
 
RISKS RELATING TO THE BUSINESS OF PARADIGM
 
  Uncertainty of Future Profitability; Need for Additional Funds. Paradigm's
recent operations have consumed substantial amounts of cash and have generated
net losses. Paradigm believes that it will require additional cash infusions
from private placements or other equity financings to meet Paradigm's
projected working capital and other cash requirements in 1998. The sale or
issuance of additional equity or convertible debt securities could result in
additional dilution to Paradigm's stockholders. There can be no assurance that
additional financing, if required, will be available when needed or, if
available, will be on terms acceptable to Paradigm.
 
  Continuing Losses and Doubtful Ability to Continue as a Going Concern. As a
result of Paradigm's net losses, and Paradigm's dependence on additional
financing, Paradigm's independent accountants' report on Paradigm's December
31, 1997 financial statements includes an explanatory paragraph indicating
that these matters raise a substantial doubt about Paradigm's ability to
continue as a going concern. Paradigm is seeking to raise additional equity.
However, there can be no assurance that Paradigm's efforts will be successful.
 
  Dilution of Common Stock. The issuance of additional shares of Common Stock
upon conversion of the Series A Preferred Stock, Series B Preferred Stock and
Series C Preferred Stock will have a dilutive effect on the Common Stock
outstanding prior to such issuances.
 
  Fluctuations in Quarterly Results. Paradigm has experienced significant
quarterly fluctuations in operating results and anticipates that these
fluctuations will continue. These fluctuations have been caused by a number of
 
                                      19
<PAGE>
 
factors, including changes in manufacturing yields by contracted
manufacturers, changes in the mix of products sold, the timing of new product
introductions by Paradigm or its competitors, cancellation or delays of
purchases of Paradigm's products, the gain or loss of significant customers,
the cyclical nature of the semiconductor industry and the consequent
fluctuations in customer demand for Paradigm's devices and the products into
which they are incorporated, and competitive pressures on prices. A decline in
demand in the markets served by Paradigm, lack of success in developing new
markets or new products, or increased research and development expenses
relating to new product introductions could have a material adverse effect on
Paradigm. Moreover, because Paradigm sets spending levels in advance of each
quarter based, in part, on expectations of product orders and shipments during
that quarter, a shortfall in revenue in any particular quarter as compared to
Paradigm's plan could have a material adverse effect on Paradigm.
 
  Declining SRAM Prices. Beginning in late 1995 and continuing into 1996, 1997
and 1998, the market for certain SRAM devices experienced a significant excess
supply relative to demand, which resulted in a significant downward trend in
prices. The market for Paradigm's products could continue to experience a
downward trend in pricing which could adversely affect Paradigm's operating
results. Paradigm's ability to maintain or increase revenues in light of the
current downward trend in product prices will be highly dependent upon its
ability to increase unit sales volumes of existing products and to introduce
and sell new products in quantities sufficient to compensate for the
anticipated declines in average selling prices of existing products. Declining
average selling prices will also adversely affect Paradigm's gross margins
unless Paradigm is able to reduce its costs per unit to offset such declines.
There can be no assurance that Paradigm will be able to increase unit sales
volumes, introduce and sell new products or reduce its costs per unit.
 
  The semiconductor industry is highly cyclical and has been subject to
significant economic downturns at various times, characterized by diminished
product demand, production overcapacity and accelerated erosion of average
selling prices. During 1996 and throughout 1997, the market for certain SRAM
devices experienced an excess supply relative to demand which resulted in a
significant downward trend in prices. Paradigm expects to continue to
experience a downward trend in pricing which could adversely affect Paradigm's
operating margins. The selling prices that Paradigm is able to command for its
products are highly dependent on industry-wide production capacity and demand,
and as a consequence Paradigm could experience rapid erosion in product
pricing which is not within the control of Paradigm and which could adversely
effect Paradigm's operating results. Paradigm expects that additional SRAM
production capacity will become increasingly available in the foreseeable
future, and such additional capacity may adversely affect Paradigm's margins
and competitive position. In addition, Paradigm may experience period-to-
period fluctuations in operating results because of general semiconductor
industry conditions, overall economic conditions, or other factors. Paradigm's
business is also subject to the risks associated with the imposition of
legislation and regulations relating to the import or export of semiconductor
products.
 
  Risks Relating to Low-Priced Stocks. Prior to August 22, 1997, Paradigm's
Common Stock was listed on the Nasdaq National Market (the "NNM"). In order
for continued listing on the NNM, however, Paradigm was required to, maintain
(1) $4,000,000 in net tangible assets because it has sustained losses from
continuing operations and/or net losses in three of its four most recent
fiscal years, (2) a $2,000,000 market value of the public float, (3)
$1,000,000 in total capital and surplus, (4) a minimum bid price of $1.00 per
share and (5) two market-makers. As of June 30, 1997, Paradigm was not in
compliance with items (1) and (4) above.
 
  On July 15, 1997, the Nasdaq Stock Market ("Nasdaq") staff notified Paradigm
of a bid price deficiency and provided a 90-day grace period within which to
regain compliance with this requirement. On August 8, 1997, Nasdaq, based on a
review of Paradigm's trading history from July 8 to August 8, 1997, indicated
that Paradigm had regained compliance with the minimum closing bid price
requirement of $1.00. On August 20, 1997, Nasdaq informed Paradigm that due to
its failure to comply with the terms of the maintenance qualifications
exception granted to Paradigm, Paradigm's Common Stock would be removed from
the NNM and listed on the SmallCap Market ("SCM") effective August 22, 1997,
pursuant to a waiver to the initial inclusion bid price requirement.
 
 
                                      20
<PAGE>
 
  On August 22, 1997, Paradigm announced that effective on such date
Paradigm's Common Stock, formerly listed on the NNM, would be listed on the
SCM, pursuant to a waiver to the initial inclusion bid price requirement.
Paradigm's continued listing on the SCM is contingent upon Paradigm meeting
the maintenance requirements.
 
  Substantial changes in Nasdaq initial listing and maintenance requirements
became effective on February 23, 1998. These changes materially enhance the
quantitative threshold criteria necessary to qualify for initial entry and
continued listing on Nasdaq. In addition, corporate governance requirements,
formerly applicable to the NNM for the first time, have been extended to the
SCM. These changes require that companies listed on the SCM maintain (i)
$2,000,000 in net tangible assets (total assets less total liabilities and
goodwill), a market capitalization of $35,000,000, or $500,000 in net income
for two of the last three years, (ii) a $1,000,000 market value for the public
float, (iii) two market-makers, and (iv) a minimum bid price of $1.00 per
share.
 
  After the new maintenance requirements became effective, Paradigm was
notified that it was not in compliance with the new minimum bid price
requirement and that Paradigm would have 90-calendar days, which expired May
28, 1998, in order to regain compliance. Paradigm may regain compliance if its
securities trade at or above the minimum bid price requirement for at least
ten consecutive trade days. If after 90 days Paradigm has not regained
compliance, Nasdaq will issue a delisting letter and Paradigm may request a
hearing at that time, which will generally stay delisting until the hearing
has been completed. Paradigm stockholders, at a Special Meeting of
Stockholders held on May 1, 1998, approved a ten-for-one reverse stock split
of Paradigm's Common Stock such that every ten shares were combined into one
share of Common Stock, par value $.01 per share. The stock split increased the
price per share of Paradigm's Common Stock sufficiently to bring such price
over $1.00 per share for a period of more than ten trading days. No assurances
can be made that such stock will continue to trade above $1.00 per share or
that Paradigm will be in compliance with the Nasdaq listing requirements.
 
  If Paradigm's securities are delisted from Nasdaq, trading, if any, of
Paradigm's securities would thereafter have to be conducted in the non-Nasdaq
over-the-counter market. In such event, an investor could find it more
difficult to dispose of, or to obtain accurate quotations as to the market
value of, Paradigm's securities. In addition, if the Common Stock were to
become delisted from trading on Nasdaq and the trading price of the Common
Stock were to remain below $5.00 per share, trading in Paradigm's Common Stock
would also be subject to the requirements of certain rules promulgated under
the Securities Exchange Act of 1934, as amended (the "Exchange Act"), which
require additional disclosure by broker-dealers in connection with any trades
involving a stock defined as a penny stock (generally, any non-Nasdaq equity
security that has a market price of less than $5.00 per share, subject to
certain exceptions.) The additional burdens imposed upon broker-dealers by
such requirements could discourage broker-dealers from effecting transactions
in the Common Stock, which could severely limit the market liquidity of the
Common Stock and the ability of investors to trade Paradigm's Common Stock.
See "--Risks Relating to Low-Priced Stock; Possible Effect of "Penny Stock'
Rules on Liquidity for Paradigm's Securities." Paradigm's Common Stock
continues to be below the $1.00 minimum bid price requirement. If Paradigm's
securities remain below the minimum bid price requirement, it could result in
Paradigm's securities being delisted from Nasdaq. There can be no assurances
that Paradigm's securities will meet the minimum bid price requirements or any
of the other continued listing requirements in the future.
 
  Risks Relating to Low-Priced Stock; Possible Effect of "Penny Stock" Rules
on Liquidity for Paradigm's Securities. If Paradigm's securities were not
listed on a national securities exchange nor listed on a qualified automated
quotation system, they may become subject to Rule 15g-9 under the Exchange
Act, which imposes additional sales practice requirements on broker-dealers
that sell such securities to persons other than established customers and
"accredited investors" (generally, individuals with a net worth in excess of
$1,000,000 or annual incomes exceeding $200,000 or $300,000 together with
their spouse). For transactions covered by Rule 15g-9, a broker-dealer must
make a special suitability determination for the purchaser and have received
the purchaser's written consent to the transaction prior to sale.
Consequently, such Rule may affect the ability of broker-dealers to sell
Paradigm's securities and may affect the ability of purchasers to sell any of
Paradigm's securities in the secondary market.
 
 
                                      21

  The Commission has adopted regulations that define a "penny stock" to be any
equity security that has a market price (as therein defined) of less than
$5.00 per share or with an exercise price of less than $5.00 per share,
subject to certain exceptions. For any transaction involving a penny stock,
unless exempt, the rules require delivery, prior to any transaction in a penny
stock, of a disclosure schedule prepared by the Commission relating to the
penny stock market. Disclosure is also required to be made about sales
commissions payable to both the broker-dealer and the registered
representative and current quotations for the securities. Finally, monthly
statements are required to be sent disclosing recent price information for the
penny stock held in the account and information on the limited market in penny
stock.
 
  The foregoing required penny stock restrictions will not apply to Paradigm's
securities if Paradigm meets certain minimum net tangible assets or average
revenue criteria. If applicable, there can be no assurance that Paradigm's
securities will qualify for exemption from the penny stock restrictions. In
any event, even if Paradigm's securities were exempt from such restrictions,
Paradigm would remain subject to Section 15(b)(6) of the Exchange Act, which
gives the Commission the authority to restrict any person from participating
in a distribution of penny stock, if the Commission finds that such a
restriction would be in the public interest.
 
  If Paradigm's securities were subject to the rules on penny stocks, the
market liquidity for Paradigm's securities could be materially adversely
affected.
 
  Dependence on New Products and Technologies. The market for Paradigm's
products is characterized by rapidly changing technology, short product life
cycles, cyclical oversupply and rapid price erosion. Average selling prices
for many of Paradigm's products have generally decreased over the products'
life cycles in the past and are expected to decrease in the future.
Accordingly, Paradigm's future success will depend, in part, on its ability to
develop and introduce on a timely basis new products and enhanced versions of
its existing products which incorporate advanced features and command higher
prices. The success of new product introductions and enhancements to existing
products depends on several factors, including Paradigm's ability to develop
and implement new product designs, achievement of acceptable production yields
and market acceptance of customers' end products. In the past, Paradigm has
experienced delays in the development of certain new and enhanced products.
Based upon the increasing complexity of both modified versions of existing
products and planned new products, such delays could occur again in the
future. Further, the cost of development can be significant and is difficult
to forecast. In addition, there can be no assurance that any new or enhanced
products will achieve or maintain market acceptance. If Paradigm is unable to
design, develop and introduce competitive products or to develop new or
modified designs on a timely basis, Paradigm's operating results will be
materially adversely affected.
 
  Dependence on Foundries and Other Third Parties. Paradigm is in the process
of seeking wafer supply from other offshore foundries, and anticipates that it
will conduct business with other foundries by delivering written purchase
orders specifying the particular product ordered, quantity, price, delivery
date and shipping terms and, therefore, such foundries will not be obligated
to supply products to Paradigm for any specific period, in any specific
quantity or at any specified price, except as may be provided in a particular
purchase order. Reliance on outside foundries involves several risks,
including constraints or delays in timely delivery of Paradigm's products,
reduced control over delivery schedules, quality assurance, potential costs
and loss of production due to seismic activity, weather conditions and other
factors. To the extent a foundry terminates its relationship with Paradigm, or
should Paradigm's supply from a foundry be interrupted or terminated for any
other reason, Paradigm may not have a sufficient amount of time to replace the
supply of products manufactured by the foundry. Should Paradigm be unable to
obtain a sufficient supply of products to enable it to meet demand, it could
be required to allocate available supply of its products among its customers.
Until recently, there has been a worldwide shortage of advanced process
technology foundry capacity and there can be no assurance that Paradigm will
obtain sufficient foundry capacity to meet customer demand in the future,
particularly if that demand should increase. Paradigm is continuously
evaluating potential new sources of supply. However, the qualification process
and the production ramp-up for additional foundries could take longer than
anticipated, and there can be no assurance that such sources will be able or
willing to satisfy Paradigm's requirements on a timely basis or at acceptable
quality or per unit prices.
 
                                      22
<PAGE>
 
  Constraints or delays in the supply of Paradigm's products, whether because
of capacity constraints, unexpected disruptions at the current or future
foundries or assembly houses, delays in obtaining additional production at the
existing foundry or in obtaining production from new foundries, shortages of
raw materials or other reasons, could result in the loss of customers and
other material adverse effects on Paradigm's operating results, including
effects that may result should Paradigm be forced to purchase products from
higher cost foundries or pay expediting charges to obtain additional supply.
 
  Litigation. On August 12, 1996, a securities class action lawsuit was filed
in Santa Clara County Superior Court against Paradigm and Michael Gulett,
Robert McClelland, Richard A. Veldhouse and Chiang Lam (the "Paradigm
Defendants") and PaineWebber, Inc. The class alleged by plaintiffs consisted
of purchasers of Paradigm Common Stock from November 20, 1995 to March 22,
1996, inclusive (the "Class Period"). The complaint alleges negligent
misrepresentation, fraud and deceit, breach of fiduciary duty and violations
of certain provisions of the California Corporate Securities Law and Civil
Code. The plaintiffs seek an unspecified amount of compensatory and punitive
damages. Plaintiffs allege, among other things, that the Paradigm Defendants
wrongfully represented that Paradigm would have protection against adverse
market conditions in the semiconductor market based on Paradigm's focus on
high speed, high performance semiconductor products. Plaintiffs allege that
the Paradigm Defendants made these alleged misrepresentations to enable: (i)
insiders to sell their shares at a profit, (ii) Paradigm's stock price to be
positioned for a secondary offering of 243,250 shares of stock (which was
later withdrawn) and (iii) Paradigm to acquire NewLogic (which acquisition was
later accomplished in exchange for 31,439 shares of Paradigm's Common Stock
and cash). Plaintiffs allege defendants McClelland, McDonald and Veldhouse
respectively acquired 55, 54 and 63 shares of the Company's stock on January
2, 1996 at a price of $114.80 per share and sold all of the stock on the same
day at a price of $135.00 per share. Plaintiffs further allege (i) defendant
McClelland sold 700 shares of Paradigm's stock on or about February 22, 1996
at a price of $145.00 per share, (ii) defendant Lam sold 313 shares of
Paradigm's stock on or about February 23, 1996 at a price of $150.00 per
share, which Shares were acquired by exercise of options on January 2, 1996 at
a price of $5.00 per share and (iii) defendant McClelland sold 100 shares of
the Company's stock on February 26, 1996 at a price of $165.00. The Paradigm
Defendants intend to vigorously defend the action. On September 30, 1996, the
Paradigm Defendants filed a demurrer seeking to have plaintiffs' entire
complaint dismissed with prejudice. On December 12, 1996, the Court sustained
the demurrer as to all of the causes of action against Michael Gulett and as
to all causes of actions, except for violation of certain provisions of the
California Corporate Securities Law, against the remaining Paradigm
Defendants. The Court, however, granted plaintiffs leave to amend the
complaint to attempt to cure the defects which caused the Court to sustain the
demurrer. Plaintiffs failed to amend within the allotted time. On January 8,
1997, the Paradigm Defendants filed an answer to the complaint denying any
liability for the acts and damages alleged by the plaintiffs. Plaintiffs have
since served the Paradigm Defendants with discovery requests for production of
documents and interrogatories, to which the Paradigm Defendants have
responded. Plaintiffs have also subpoenaed documents from various third
parties. The Paradigm Defendants have served the plaintiffs with an initial
set of discovery requests, to which plaintiffs have responded. The Paradigm
Defendants also took the depositions of the named plaintiffs on April 9, 1997.
On January 15, 1997, plaintiffs filed a motion to certify the matter as a
class action. Plaintiffs sought by their motion to certify a nationwide class
of those who purchased Paradigm's stock during the Class Period. After several
hearings and continuances, on February 9, 1998 the Court certified a class
consisting only of California purchasers of Paradigm's stock during the Class
Period. On April 9, 1998, the Court granted Plaintiffs' motion to amend their
complaint to incorporate factual allegations derived from the May 19, 1997
action described below. The Paradigm Defendants' have filed a demurrer in
response to the amended complaint, which is set for hearing on August 6, 1998.
There can be no assurance that Paradigm will be successful in the defense of
this action. If unsuccessful in the defense of any such claim, Paradigm's
business, operating results and cash flows could be materially adversely
affected.
 
  On February 21, 1997, an additional purported class action lawsuit was filed
in Santa Clara County Superior Court against Paradigm and Michael Gulett,
Robert McClelland, Richard A. Veldhouse, Chiang Lam, PaineWebber, Inc. and
Smith Barney (the "Paradigm Defendants"), with causes of action and factual
allegations essentially identical to those of the August 12, 1996 class action
lawsuit. Prior to the hearing on the Paradigm
 
                                      23
<PAGE>
 
Defendants' demurrer to the initial complaint, plaintiff amended his complaint
to incorporate factual allegations derived from the May 19, 1997 lawsuit
described below. The Paradigm Defendants filed a demurrer to the amended
complaint, which was heard on September 9, 1997. On September 10, 1997, the
Court issued an order sustaining the Paradigm Defendants' demurrer as to all
causes of action without leave to amend. A judgment in favor of the Paradigm
Defendants dismissing the entire complaint was entered by the Court on
September 23, 1997. Plaintiff has appealed the decision and filed a brief in
support of his appeal. The Paradigm Defendants' responsive brief was filed
March 30, 1998. There can be no assurances that Paradigm will be successful in
defeating the appeal. If unsuccessful in defeating the appeal, Paradigm's
business, operating results and cash flows could be materially adversely
affected.
 
  On May 19, 1997, three former employees of Paradigm, Thomas Campbell, James
Zulliger and Mark Wagenhals, filed an action in Santa Clara County Superior
Court. The complaint names as defendants Paradigm, Michael Gulett, Richard
Veldhouse, Dennis McDonald and Chiang Lam. Plaintiffs filed with the complaint
a notice that they consider their case related legally and factually to the
August 12, 1996 class action lawsuit described above. The complaint alleges
fraud, breach of fiduciary duty and violations of certain provisions of the
California Corporate Securities Law and Civil Code. Plaintiffs allege that
they purchased Paradigm's stock at allegedly inflated prices and were damaged
thereby. The plaintiffs sought an unspecified amount of compensatory,
rescissory and/or punitive damages. Defendants responded to the complaint on
September 12, 1997 by filing a demurrer as to all causes of action. Prior to
the hearing on the demurrer, Plaintiffs amended their complaint to identify
two allegedly fraudulent sale transactions. In particular, Plaintiffs allege
that Paradigm reported a sale of $1,650,000 worth of products to NexGen, Inc.,
one of Paradigm's customers, that was not a legitimate sale. Plaintiffs allege
that the order was sent to the shipping floor during the evening shift on
December 31, 1995, to be out before midnight, was included in year-end sales
and was returned, apparently untouched, in April 1996. In addition, plaintiffs
allege that on March 31, 1996, Paradigm shipped $1,440,080 worth of products
to Arco, one of Paradigm's distributors, that was not a legitimate order.
Plaintiffs allege this shipment was later returned untouched for full credit.
Defendants filed a demurrer as to all causes of action in the amended
complaint, which was heard on April 2, 1998. That same day, the Court issued
its order sustaining the demurrer on multiple grounds, but granted Plaintiffs
leave to amend the complaint by May 15, 1998. Defendants' filed a demurrer in
response to the second amended complaint, which is set for hearing on
September 3, 1998. Plaintiffs have served Paradigm and two of the individual
defendants with requests for production of documents, to which Paradigm and
the individual defendants have responded. Plaintiffs also took the deposition
of a third party on April 23, 1998. Paradigm has served plaintiff with form
interrogatories, to which they have responded. Paradigm also took the
Plaintiffs' depositions on April 20-22, 1998. The deposition of one of the
plaintiffs is continuing. There can be no assurance that Paradigm will be
successful in defense of this action. If unsuccessful in the defense of any
such claim, Paradigm's business, operating results and cash flows could be
materially adversely affected.
 
  On May 19, 1998, an additional securities class action lawsuit was filed in
the United States District Court for the Northern District of California
against Paradigm and Michael Gulett, Robert McClelland, Richard A. Veldhouse
and Chiang Lam. The complaint alleges violations of section 10(b) of the
Exchange Act, Securities and Exchange Commission Rule 10b-5 and section 20(a)
of the Exchange Act. Plaintiff alleges the same class and the same substantive
factual allegations that are contained in the August 12, 1996 action as
amended. Plaintiffs seek an unspecified amount of compensatory and punitive
damages. The Paradigm Defendants intend to vigorously defend the action.
Defendants' response to the complaint is due to be filed on July 27, 1998.
There can be no assurances that Paradigm will be successful in the defense of
this action. If unsuccessful in the defense of any such claim, Paradigm's
business, operating results and cash flows could be materially adversely
affected.
 
  Paradigm is involved in various other litigation and potential claims. Due
to the inherent uncertainty of litigation, management is not able to
reasonably estimate losses that may be incurred in relation to this
litigation. However, based on the facts presently known, management believes
that the resolution of these matters will not have a material adverse impact
on the results of operations or the financial position of Paradigm.
 
                                      24

  Product and Customer Concentration; Dependence on Telecommunications and
Computer Industries. Currently, substantially all of Paradigm's sales are
derived from the sale of SRAM products. Substantially all of Paradigm's
products are incorporated into telecommunications and computer-related
products. The telecommunications and computer industries have recently
experienced strong unit sales growth, which has increased demand for
integrated circuits, including the memory products offered by Paradigm.
However, industries have from time to time experienced cyclical, depressed
business conditions. Such industry downturns have historically resulted in
reduced product demand and declining average selling prices. Paradigm's
business and operating results could be materially and adversely affected by a
downturn in the telecommunications or computer industries in the future.
 
  Competition. The semiconductor industry is intensely competitive and is
characterized by rapidly changing technology, short product life cycles,
cyclical oversupply and rapid price erosion. Paradigm competes with large
domestic and international semiconductor companies, most of which have
substantially greater financial, technical, marketing, distribution and other
resources than Paradigm. Paradigm's principal competitors in the high
performance SRAM market include Motorola and Micron Technology. Other
competitors in the SRAM market include Alliance Semiconductor, Cypress
Semiconductor, Integrated Device Technology, Integrated Silicon Solution,
Samsung and numerous other large and emerging semiconductor companies. In
addition, other manufacturers can be expected to enter the high speed, high
density SRAM market.
 
  The ability of Paradigm to compete successfully depends on many elements
outside its control, including the rate at which customers incorporate
Paradigm's products into their systems, the success of such customers in
selling those systems, Paradigm's protection of its intellectual property, the
number, nature and success of its competitors and their product introductions,
and general market and economic conditions. In addition, Paradigm's success
will depend in large part on its ability to develop, introduce and manufacture
in a timely manner products that compete effectively on the basis of product
features (including speed, density, die size and packaging), availability,
quality, reliability and price, together with other factors including the
availability of sufficient manufacturing capacity and the adequacy of
production yields. There is no assurance that Paradigm will be able to compete
successfully in the future.
 
  Strategic Relationships; Potential Competition. Paradigm, pursuant to
certain licenses of its technology, has entered into strategic relationships
with NKK. Paradigm has had a long-standing business relationship with NKK
which began in October 1992. Paradigm, NKK and affiliates of NKK entered into
several equity and debt transactions which provided start-up and development
funding to Paradigm. Given the long-standing relationship, Paradigm and NKK
entered into three technology license and development agreements which provide
for NKK to supply Paradigm a specified number of 1M SRAMs for three years.
These agreements provided funding to Paradigm.
 
  Paradigm's business relationship with Atmel began in April 1995 when
pursuant to certain agreements, Atmel purchased a substantial number of shares
of Paradigm's capital stock from Paradigm, certain stockholders of Paradigm
who had been unsecured creditors of Paradigm as of the reorganization and from
Paradigm's equipment lessors. Atmel also acquired certain warrants to purchase
shares of Paradigm's Common Stock. In 1995, Paradigm and Atmel entered into a
five-year License and Manufacturing Agreement pursuant to which Atmel would
provide the capacity to manufacture wafers at its wafer manufacturing
facility. Paradigm entered into such agreement with Atmel because Atmel
provided Paradigm with significant wafer manufacturing capacity when such
capacity was in short supply.
 
  Paradigm previously licensed the design and process technology for
substantially all of its products at such time, including certain of its 256K,
1M and 4M products, to NKK as a source of revenue. Paradigm has not licensed
any of its current products to NKK. In the future, Paradigm may compete with
NKK with respect to all of such products in certain Pacific Rim countries,
North America and Europe and, as to certain of its 256K and 1M products, in
the rest of the world. In 1995, NKK commenced production of products using
Paradigm's design and process technologies, and therefore may become a more
significant competitor of Paradigm. Any such competition with NKK could
adversely affect Paradigm. Paradigm has also licensed to Atmel the right to
produce
 
                                      25
<PAGE>
 
certain of its SRAM products which provided significant wafer manufacturing
capacity. As a result, Paradigm is likely to compete with Atmel with respect
to such products. Because Atmel has greater resources than Paradigm and has
foundry capacity, any such competition could adversely affect Paradigm. To the
extent that Paradigm enters into similar arrangements with other companies, it
may compete with such companies as well.
 
  Dependence on Patents, Licenses and Intellectual Property; Potential
Litigation. Paradigm intends to continue to pursue patent, trade secret, and
mask work protection for its semiconductor process technologies and designs.
To that end, Paradigm has obtained certain patents and patent licenses and
intends to continue to seek patents on its inventions and manufacturing
processes, as appropriate. The process of seeking patent protection can be
long and expensive, and there is no assurance that patents will be issued from
currently pending or future applications or that, if patents are issued, they
will be of sufficient scope or strength to provide meaningful protection or
any commercial advantage to Paradigm. In particular, there can be no assurance
that any patents held by Paradigm will not be challenged, invalidated or
circumvented, or that the rights granted thereunder will provide competitive
advantage to Paradigm. Paradigm also relies on trade secret protection for its
technology, in part through confidentiality agreements with its employees,
consultants and third parties. There can be no assurance that these agreements
will not be breached, that Paradigm will have adequate remedies for any
breach, or that Paradigm's trade secrets will not otherwise become known to or
independently developed by others. In addition, the laws of certain
territories in which Paradigm's products are or may be developed, manufactured
or sold may not protect Paradigm's products and intellectual property rights
to the same extent as the laws of the United States.
 
  There has been substantial litigation regarding patent and other
intellectual property rights in the semiconductor industry. In the future,
litigation may be necessary to enforce patents issued to Paradigm, to protect
trade secrets or know-how owned by Paradigm, or to defend Paradigm against
claimed infringement of the rights of others and to determine the scope and
validity of the proprietary rights of others. Paradigm has from time to time
received, and may in the future receive, communications alleging possible
infringement of patents or other intellectual property rights of others. Any
such litigation could result in substantial cost to and diversion of effort by
Paradigm, which could have a material adverse effect on Paradigm. Further,
adverse determinations in such litigation could result in Paradigm's loss of
proprietary rights, subject Paradigm to significant liabilities to third
parties, require Paradigm to seek licenses from third parties or prevent
Paradigm from manufacturing or selling its products, any of which could have a
material adverse effect on Paradigm.
 
  International Operations; Currency Fluctuations. A significant portion of
Paradigm's sales are attributable to sales outside the United States,
primarily in Asia and Europe. In fiscal 1997, Asia and Europe accounted for
approximately 7% and 5%, respectively, of Paradigm's revenues. Paradigm
expects that international sales will continue to represent a significant
portion of its sales. Paradigm currently conducts business in Singapore,
Japan, Taiwan, Hong Kong, United Kingdom, Belgium, Sweden, France, Germany and
Israel. In addition, Paradigm expects that a significant portion of its
products will be manufactured by independent third parties in Asia. Therefore,
Paradigm is subject to the risks of conducting business internationally, and
both manufacturing and sales of Paradigm's products may be adversely affected
by political and economic conditions abroad. Protectionist trade legislation
in either the United States or foreign countries, such as a change in the
current tariff structures, export compliance laws or other trade policies,
could adversely affect Paradigm's ability to have products manufactured or
sell products in foreign markets. Paradigm cannot predict whether quotas,
duties, taxes or other charges or restrictions will be imposed by the United
States, Hong Kong, Japan, Taiwan or other countries upon the importation or
exportation of Paradigm's products in the future, or what effect any such
actions would have on its relationship with NKK or other manufacturing
sources, or its general business, financial condition and results of
operations. In addition, there can be no assurance that Paradigm will not be
adversely affected by currency fluctuations in the future. The prices for
Paradigm's products are denominated in U.S. dollars and all of Paradigm's
business transactions are in U.S. dollars. Accordingly, any increase in the
value of the dollar as compared to currencies in Paradigm's principal overseas
markets would increase the foreign currency-denominated sales prices of
Paradigm's products, which may negatively affect Paradigm's sales in those
markets. Paradigm has not entered into any agreements or instruments to hedge
the risk of foreign
 
                                      26
<PAGE>
 
currency fluctuations. Currency fluctuations in the future may also increase
the manufacturing costs of Paradigm's products. Although Paradigm has not to
date experienced any material adverse effect on its operations as a result of
such international risks, there can be no assurance that such factors will not
adversely impact Paradigm's general business, financial condition and results
of operations.
 
  Employees. Paradigm's future success will be heavily dependent upon its
ability to attract and retain qualified technical, managerial, marketing and
financial personnel. Paradigm has experienced a high degree of turnover in
personnel, including at the senior and middle management levels. The
competition for such personnel is intense and includes companies with
substantially greater financial and other resources to offer such personnel.
Recently, Paradigm has had to significantly reduce its work staff. There can
be no assurance that Paradigm will be able to attract and retain the necessary
personnel, and any failure to do so could have a material adverse effect on
Paradigm.
 
  Potential Volatility of Stock Price. The trading price of Paradigm's Common
Stock is subject to wide fluctuations in response to variations in operating
results of Paradigm and other semiconductor companies, actual or anticipated
announcements of technical innovations or new products by Paradigm or its
competitors, general conditions in the semiconductor industry and the
worldwide economy, and other events or factors. Paradigm's stock traded from a
high of $372.50 in August 1995 to a low of $0.563 in June 1998 (after giving
effect to the ten-for-one reverse stock split). In addition, the stock market
has in the past experienced extreme price and volume fluctuations,
particularly affecting the market prices for many high technology companies,
and these fluctuations have often been unrelated to the operating performance
of the specific companies. These market fluctuations may adversely affect the
market price of the Paradigm Common Stock.
 
  Antitakeover Effect of Certain Charter Provisions. Certain provisions of
Paradigm's Certificate of Incorporation and Bylaws and of Delaware law could
discourage potential acquisition proposals and could delay or prevent a change
in control of Paradigm. Such provisions could diminish the opportunities for a
stockholder to participate in tender offers, including tender offers at a
price above the then current market value of the Common Stock. Such provisions
may also inhibit fluctuations in the market price of the Common Stock that
could result from take-over attempts. In addition, the Board of Directors,
without further stockholder approval, may issue Preferred Stock that could
have the effect of delaying or preventing a change in control of Paradigm. The
issuance of Preferred Stock could also adversely affect the voting power of
the holders of Common Stock, including the loss of voting control to others.
 
  Year 2000. The Year 2000 issue arises because most computer hardware and
software was developed without considering the impact of the upcoming change
in the century. The hardware and software were originally designed to accept
two-digit entries rather than four-digit entries in the date code field. As a
result, certain computer systems and software packages will not be able to
correctly interpret dates beyond December 31, 1999 and thus, will interpret
dates beginning January 1, 2000 to represent January 1, 1900. This could
potentially result in computer failure or miscalculations, causing operating
disruptions, including among other things, a temporary inability to process
transactions, send invoices or engage in other ordinary activities.
 
  Paradigm has evaluated all of its computer software and database software to
identify modifications, if any, that may be required to address Year 2000
issues. Paradigm does not believe there is significant risk associated with
the Year 2000 problem. Paradigm primarily uses third-party software programs
written and updated by outside firms. Paradigm intends to test all of its
software programs during 1998 to ensure that each will work in conjunction
with the other after December 31, 1999. If unforeseeable problems arise during
the testing phase, Paradigm intends to have them corrected prior to the end of
the 1998 calendar year. Paradigm does not expect the financial cost associated
with any required modifications to have a material adverse impact on
Paradigm's results, operations or financial condition. Paradigm also relies on
third parties to ship its products. Paradigm is currently investigating
whether such third parties are Year 2000 compliant. Paradigm does not expect
that failure on the part of any third party to be Year 2000 compliant will
have a material adverse impact on its business, results of operations or
financial condition.

RISKS RELATING TO THE BUSINESS OF IXYS
 
  Please see page 123 for a glossary that defines certain technical terms used
throughout the descriptions of IXYS' risk factors and business.
 
  Factors Affecting Operating Results. IXYS' quarterly and annual operating
results are affected by a wide variety of factors that could materially
adversely affect revenues and profitability, including IXYS' ability to
introduce new products and technologies on a timely basis; the level of orders
received which can be shipped in a quarter; availability of foundry capacity
and raw materials; the timing of investments in research and development,
including tooling expenses associated with product development and pre-
production; competitive pressures on selling prices; the timing and
cancellation of customer orders; the timing and provision of pricing
projections and returns from certain distributors; fluctuations in yields;
changes in product mix; introduction of products and technologies by IXYS'
competitors; foreign currency fluctuations; cyclicality of the semiconductor
industry; seasonality; and whether IXYS' customers buy from a distributor or
directly from IXYS. IXYS markets its products to various industries including
the computers and peripherals, industrial machinery and equipment,
telecommunications, transportation, medical and other industries. A downturn
in any of IXYS' markets could materially adversely affect IXYS' business,
financial condition and results of operations. Sudden shortages of raw
materials or production capacity constraints can lead producers to allocate
available supplies or capacity to customers with resources greater than those
of IXYS, which could interrupt IXYS' ability to meet its production
obligations. Historically, average selling prices in the integrated circuits
("IC") and power semiconductor industries have decreased over the life of a
product, and as a result, the average selling prices of IXYS' products may be
subject to significant pricing pressures in the future.
 
  Customer orders typically can be canceled or rescheduled without significant
penalty to the customer. As a result, backlog may not be indicative of sales
for any future period. IXYS typically plans its production and inventory
levels based on forecasts of customer demand, which are highly unpredictable
and can fluctuate substantially. Because IXYS is continuing to increase its
operating expenses for personnel and new product development and for inventory
in anticipation of increasing sales levels, operating results would be
adversely affected if increased sales are not achieved. In addition, a large
part of IXYS' expenses are fixed and difficult to reduce in response to any
revenue shortfalls. From time to time, in response to anticipated long lead
times to obtain inventory and materials from its foundries, IXYS may order in
advance of anticipated customer demand, which might result in excess inventory
levels if expected orders fail to materialize or other factors render the
customer's product less marketable.
 
  As a result of the foregoing or other factors, IXYS may experience material
fluctuations in future operating results on a quarterly or annual basis which
could materially and adversely affect its business, financial condition and
results of operations. Due to the foregoing factors, it is likely that in some
period, IXYS' revenues or operating results will be below the expectations of
public market analysts and investors. In such event, the price of the IXYS
Common Stock would likely be materially adversely affected.
 
  Manufacturing. IXYS manufactures its products in manufacturing facilities
which are owned and operated by IXYS and by utilizing outside wafer foundries
and independent subcontract assembly facilities. The fabrication of discrete
and integrated circuits is a highly complex and precise process. Minute levels
of contaminants in the manufacturing environment, difficulties in the
fabrication process, defects in the masks used to print circuits on a wafer,
manufacturing equipment failure, wafer breakage or other factors can cause a
substantial percentage of wafers to be rejected or numerous die on each wafer
to be nonfunctional. In the event that IXYS increases its manufacturing
output, there can be no assurance that IXYS will not experience a decrease in
manufacturing yields. Moreover, there can be no assurance that IXYS in general
will be able to maintain acceptable manufacturing yields in the future. To the
extent IXYS does not achieve acceptable manufacturing yields or experiences
product shipment delays, its business, financial condition and results of
operations would be materially and adversely affected. To achieve adequate
production yields, IXYS may need to expand its existing facilities. There can
be no assurance that IXYS will be able to cost-effectively expand its existing
 
                                      28
<PAGE>
 
facilities in a timely manner, if at all, or achieve adequate production
yields from such expanded facilities. If IXYS fails to cost-effectively expand
its existing facility in a timely manner, its business, financial condition
and results of operations may be adversely affected. See "IXYS Business--
Manufacturing."
 
  Dependence on Third Parties for Wafer Fabrication and Assembly. Forty-four
percent (44%) of the revenue in fiscal year 1998 came from wafers acquired
from outside foundries. Dependency on outside foundries is expected to grow.
IXYS has arrangements with five wafer foundries, of which two foundries
provide 99% of the wafers provided to IXYS by outside foundries. IXYS has a
supply agreement with one of these foundries, Samsung Electronics Co.
("Samsung"). There can be no assurance that this agreement will be extended
beyond its current terms. IXYS expects that it will continue to rely
significantly on outside foundries in the future. There are significant risks
associated with IXYS' reliance on outside foundries, including the lack of
assured supply of an adequate quantity of semiconductor devices, control over
delivery schedules and limited control over quality assurance, manufacturing
yields and production costs. IXYS' foundries may from time to time experience
lower than anticipated manufacturing yields, particularly in connection with
the introduction of new products and the installation and start-up of new
process technologies. There can be no assurance that IXYS' foundries will not
experience lower than expected manufacturing yields in the future which could
materially and adversely affect IXYS' business, financial condition and
results of operations.
 
  The ability of each foundry to provide semiconductor devices to IXYS is
limited by the foundry's available capacity. Therefore, IXYS' foundry
suppliers could choose to prioritize capacity for other customers or uses or
reduce or eliminate deliveries to IXYS on short notice. Accordingly, there is
no assurance that IXYS' foundries will allocate sufficient capacity to satisfy
IXYS' requirements. In addition, IXYS has been, and expects in the future to
be, particularly dependent upon a limited number of foundries for its power
MOSFET requirements. To address foundry capacity constraints, other
semiconductor suppliers that rely on third-party foundries have utilized
various arrangements, including equity investments in or loans to independent
wafer manufacturers in exchange for guaranteed production capacity, joint
ventures to own and operate foundries or take or pay contracts that commit a
company to purchase specified quantities of wafers over extended periods.
While IXYS is not currently a party to any such arrangements, it may be
required to enter into such arrangements in the future, and there can be no
assurance that it will be successful in this regard. Any such arrangements
could require IXYS to commit substantial capital and grant licenses to its
technology. The need to commit substantial capital may require IXYS to obtain
additional debt or equity financing, which could result in dilution to IXYS'
stockholders. There can be no assurance that such additional financing, if
required, will be available when needed or, if available, will be obtained on
terms acceptable to IXYS.
 
  There can be no assurance that material disruptions in supply will not occur
in the future. In such event, IXYS may have to identify and secure additional
foundry capacity and may be unable to identify or secure additional foundry
capacity from another manufacturer, particularly at the levels that IXYS
currently anticipates such foundries to provide. Even if such capacity is
available from another manufacturer, the qualification process could take six
months or longer. If IXYS were unable to qualify alternative manufacturing
sources for existing or new products in a timely manner or if such sources
were unable to produce semiconductor devices with acceptable manufacturing
yields and at acceptable prices, IXYS' business, financial condition and
results of operations would be materially and adversely affected.
 
  IXYS relies on independent subcontract assembly facilities for its discrete
and IC product requirements. IXYS' reliance on independent assemblers may
subject IXYS to supply constraints and longer manufacturing cycle times, which
could delay deliveries of IXYS' products to its customers. IXYS has from time
to time experienced competition from other manufacturers seeking assembly of
circuits by independent contractors, which could further constrain supply.
Such constraints or delays might result in the loss of customers, limitations
or reductions in IXYS' revenues or other material adverse effects on IXYS'
business, financial condition or results of operations. Although IXYS
currently believes that alternative assembly sources could be obtained, there
can be no assurance that such alternative sources could be quickly obtained or
obtained at acceptable prices. Failure to obtain such alternative assembly
sources in a timely manner, or at all, would have a material adverse effect on
IXYS' business, financial condition and results of operations. IXYS' reliance
on independent
 
                                      29
<PAGE>
 
assemblers involves a number of other risks, including reduced control over
quality assurance and costs. The inability of such third parties to deliver
products of acceptable quality and at an acceptable cost could have a material
adverse effect on IXYS' business, financial condition and results of
operations. See "IXYS Business--Manufacturing."
 
  Dependence on Suppliers. IXYS purchases silicon wafers from Sumitomo Sitix
Silicon, Inc., Epitech and Wacker AG, with whom IXYS does not have long term
supply agreements. Any of these suppliers could eliminate or terminate IXYS'
supply of wafers at any time. IXYS' reliance on a limited number of suppliers
involves several risks, including potential inability to obtain an adequate
supply of silicon wafers and reduced control over the price, timely delivery,
reliability and quality of the silicon wafers. There can be no assurance that
problems will not occur in the future with suppliers.
 
  The silicon wafers used as starting material for power semiconductors are
different from the type of silicon wafers used for ICs. Power semiconductors
require silicon wafers with thicker layers for higher voltage blocking
capability. In addition, the IC industry has been moving toward the use of 8"
and larger diameter wafers, which require large capital equipment expenditures
from silicon wafer suppliers and IC manufacturers. Currently, the power
semiconductor industry generally uses 4" and 5" wafers, although IXYS
anticipates that the power semiconductor industry will move toward 6" wafers
for at least some applications. To the extent the power semiconductor industry
moves toward the use of larger wafer sizes, IXYS or its suppliers will be
required to invest in the processing equipment necessary for these larger
diameter wafers. Power semiconductor manufacturers currently rely on the
availability of smaller diameter silicon wafers for their needs, and there is
a risk that silicon wafer suppliers will move to larger diameter wafers to
cater to the IC industry, thus limiting the supply of the more economical 4"
and 5" wafers and forcing IXYS to make the large capital expenditures
necessary for processing the larger diameter wafers. The unavailability of 4"
and 5" silicon wafers in sufficient quantities to meet IXYS' manufacturing
needs, or an increase in the price of such wafers as a result of shortages in
their supply, would have a material adverse effect on IXYS' business,
financial condition and results of operations.
 
  Because of IXYS' limited inventory of raw materials and tight manufacturing
cycles, unanticipated interruptions of supply, which have occurred
periodically in the past, could have a material adverse effect on IXYS'
business, financial condition and results of operations.
 
  Competition. The power semiconductor industry is intensely competitive and
is characterized by price competition, technological change, limited
fabrication capacity, international competition and manufacturing yield
problems. The ability of IXYS to compete successfully in this evolving
industry depends on factors both within and outside its control, including
success in designing and subcontracting the manufacture of new products that
implement new technologies, protection of Company products by effective
utilization of intellectual property laws, product quality, reliability,
price, efficiency of production, the pace at which customers incorporate IXYS'
power semiconductors into their products, success of competitors' products and
general economic conditions.
 
  IXYS encounters differing degrees of competition for its various products,
depending upon the type of product and the particular market served. Many of
IXYS' competitors are larger companies with greater financial, technical and
marketing resources than IXYS. The competitive factors in the market for IXYS'
products include overall functional performance of the products, quality,
price, reliability, breadth and availability of products, delivery time to the
customer and service. IXYS' primary competitors include Advanced Power
Technology, Fuji, International Rectifier, Harris Corporation, Motorola, Inc.,
Powerex, Inc., SGS-Thomson Microelectronics, Siemens AG and Toshiba
Corporation. Certain of these competitors may benefit from established
customer relationships that provide them with a competitive advantage. New
entrants could also attempt to obtain a share of the market for IXYS' current
and future products. There can be no assurance that IXYS will continue to be
able to compete successfully against current or new competitors or new
technologies in the future. See "IXYS Business--Competition."

  Management of International Operations; Fluctuation in Exchange Ratios. IXYS
operates a manufacturing facility in Lampertheim, Germany, relies on foundry
and assembly facilities in Asia and Europe and conducts a substantial portion
of its operations outside the United States. In fiscal 1996, 1997 and 1998,
foreign sales accounted for approximately 66%, 62% and 63%, respectively, of
IXYS' total revenues. IXYS anticipates that foreign sales will continue to
account for a significant percentage of its revenues. A significant portion of
IXYS' total revenues will therefore be subject to risks associated with
foreign operations, including unexpected changes in, and the burden of
complying with, a wide variety of legal and regulatory requirements and policy
changes, changes in tariffs, exchange rates and other barriers, political and
economic instability, difficulties in accounts receivable collection,
difficulties in managing distributors or representatives, difficulties in
staffing and managing foreign operations, difficulties in protecting IXYS'
intellectual property overseas, seasonality of sales and potentially adverse
tax consequences. IXYS is also subject to risks associated with regulations
relating to the import and export of high technology products. IXYS cannot
predict whether quotas, duties, taxes or other charges or restrictions upon
the importation or exportation of IXYS' products in the future will be
implemented by the United States or any other country. IXYS' sales of products
manufactured in, and salaries of its personnel at, its Lampertheim facility
are denominated in German marks. Fluctuations in the German mark against the
United States dollar have had, and could in the future have, a significant
impact on the Company's balance sheet and results of operations. The Company's
net income has in the past and could in the future vary significantly
depending on fluctuations in the German mark against the United States dollar.
IXYS currently does not enter into foreign currency hedging transactions.
Fluctuations in currency exchange rates has caused, and could in the future
cause, IXYS' products to become relatively more expensive to customers in a
particular country, leading to a reduction in sales or profitability in that
country. To the extent that IXYS expands its international operations or
changes its pricing practices to denominate prices in other foreign
currencies, IXYS will be exposed to even greater risks of currency
fluctuations. There can be no assurance that any of these factors will not
have a material adverse effect on IXYS' business, financial condition and
results of operations. See "IXYS Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "IXYS Business--
Environmental Matters."
 
  Management of Growth. To effectively manage its future growth, if any, IXYS
will need to implement a variety of new or expanded business and financial
systems, procedures and controls, including the improvement of its accounting,
manufacturing and other internal management systems. Currently, IXYS is in the
process of implementing a new comprehensive management information system
addressing all operational functions, including, sales, inventory, and
engineering functions. There can be no assurance that the implementation of
such systems, procedures and controls can be completed successfully, or
without disruption of IXYS' operations. Expansion of IXYS could significantly
strain IXYS' management, financial and other resources. In particular, if IXYS
seeks to increase its manufacturing capacity, it may be necessary for IXYS to
efficiently allocate any increased capacity among its products and to react to
changing market conditions, and the failure to do so would have a material
adverse effect on IXYS' business, financial condition and results of
operations. See "IXYS Business--Manufacturing."
 
  In addition, IXYS has hired and will be required to hire in the future
substantial numbers of new employees, particularly additional management
personnel. The market for such personnel has become increasingly competitive,
and the inability of IXYS to recruit, train and retain adequate numbers of
qualified personnel would adversely affect IXYS' ability to manufacture and
sell its products.
 
  As IXYS may be required to design and manufacture its products in larger
volumes, it may become more difficult for IXYS to maintain its standards of
quality and reliability, and delivery times for its products may grow longer.
Further, if IXYS is unable to expand its manufacturing capacity to meet
demand, the placement of a large order requiring the delivery of products
during a particular period might deter other customers from placing orders
with IXYS that would require development and delivery of products during the
same period.
 
  There can be no assurance that IXYS' systems, procedures, controls and
personnel will be adequate to support IXYS' operations. Failure to manage
IXYS' growth effectively could have a material adverse effect on IXYS'
business, financial condition and results of operations. See "IXYS Business--
Employees" and "--Management."
 
                                      31
<PAGE>
 
  Dependence on Patents and Proprietary Technology. IXYS relies on a
combination of patent rights, copyrights and trade secrets to protect the
proprietary elements of its products. However, there can be no assurance that
such measures will provide adequate protection for IXYS' trade secrets or
other proprietary information, that disputes with respect to the ownership of
its intellectual property rights will not arise, that IXYS' trade secrets or
proprietary technology will not otherwise become known or be independently
developed by competitors or that IXYS can otherwise meaningfully protect its
intellectual property rights. IXYS' policy is to file patent applications to
protect technology, inventions and improvements that are important to its
business. There can be no assurance that patents will issue from any of IXYS'
pending applications or that any claims allowed from existing or pending
patents will be sufficiently broad to protect IXYS' technology. While IXYS
intends to protect its intellectual property rights vigorously, there can be
no assurance that any patents held by IXYS will not be challenged, invalidated
or circumvented, or that the rights granted thereunder will provide
competitive advantages to IXYS. Furthermore, there can be no assurance that
others will not develop similar products, duplicate IXYS' products or design
around the patents owned by IXYS.
 
  IXYS also seeks to protect its trade secrets and proprietary technology, in
part, through confidentiality agreements with employees, consultants and other
parties. There can be no assurance that these agreements will not be breached,
that IXYS will have adequate remedies for any breach, or that IXYS' trade
secrets will not otherwise become known to or independently developed by
others. In addition, there can be no assurance that foreign intellectual
property laws will adequately protect IXYS' proprietary rights abroad.
 
  The assertion of claims for infringement of intellectual property rights is
common in the semiconductor industry. There can be no assurance that any
infringement claims (or claims for indemnification resulting from infringement
claims against third parties, such as customers) or claims that IXYS' patents
are invalid will not be asserted against IXYS. If infringement claims are
asserted against IXYS, IXYS may seek to obtain a license of such third party's
intellectual property rights, which may not be available under reasonable
terms or at all. If an IXYS product is found to infringe a patent, a court may
grant an injunction to prevent making, selling or using the product in the
applicable country. Litigation may be necessary to defend against claims made
by third parties, enforce patents issued to IXYS, protect trade secrets or
know-how owned by IXYS. Any such litigation could result in substantial costs
and diversion of resources and could have a material adverse effect on IXYS'
business, financial condition and results of operations. See "IXYS Business--
Patents and Licenses."
 
  Effect of Government Regulations. Power semiconductors with operating
voltages above 40 volts are subject, in some applications, to industry
regulations intended to address the safety, reliability and quality of the
products and to address environmental considerations. These regulations relate
to processes, design, materials and assembly. For example, in the United
States some high voltage products are required to pass Underwriters Laboratory
("UL") recognition for voltage isolation and fire hazard tests. Sales of power
semiconductors outside of the United States are subject to international
regulatory requirements that vary from country to country. Products used in
Europe may be required to be qualified under the Verband Deutscher
Elektrotechniker ("VDE") regulations. The process of obtaining and maintaining
required regulatory clearances can be lengthy, expensive and uncertain. The
time required to obtain approval for sale internationally may be longer or
shorter than that required for U.S. approval, and the requirements may differ.
In addition, 5% of IXYS' revenues in fiscal 1998 were derived from the sale of
products included in medical devices that are subject to extensive regulation
by numerous governmental authorities in the United States and internationally,
including the U.S. Food and Drug Administration (the "FDA"). The FDA and
certain foreign regulatory authorities impose numerous requirements with which
medical device manufacturers must comply, including adherence to Good
Manufacturing Practices ("GMP") regulations and similar regulations in other
countries, which include testing, control and documentation requirements.
Ongoing compliance with GMP and other applicable regulatory requirements is
monitored through periodic inspections by federal and state agencies,
including the FDA, and by comparable agencies in other countries. Failure to
comply with applicable regulatory requirements could result in, among other
things, the inability to include IXYS' products in approved medical devices.
Delays in receipt of or failure to receive required approvals or clearances,
the loss of previously obtained approvals or clearances, or failure to comply
with existing or future regulatory requirements would have a material adverse
effect on IXYS' business, financial condition and results of operations.
 
                                      32
<PAGE>
 
  Technological Change. The power semiconductor industry is subject to
technological change and evolving industry standards. To remain competitive,
IXYS must continue to devote significant resources to the development of new
products and new process technologies. In addition, new product announcements,
introductions or enhancements by IXYS' competitors could cause a decline in
sales or loss of market acceptance of IXYS' existing products. Because new
product development commitments must be made well in advance of sales, new
product decisions must anticipate advances in power semiconductor
manufacturing. There can be no assurance that IXYS will be able to identify
new product opportunities successfully and develop and bring to market such
new products, that IXYS will be able to respond effectively to new
technological changes or new product announcements by others or that IXYS' new
products will be accepted by the market.
 
  The markets for products incorporating power semiconductors are subject to
technological change, and there can be no assurance that as such markets
change IXYS' product offerings will remain current and suitable for them.
Certain of IXYS' new products are incorporated into a customer's products or
systems in the design stage. The value of any design win largely depends upon
the commercial success of the customer's product and on the extent to which
the design of the customer's electronic system accommodates incorporation of
components manufactured by IXYS' competitors. In addition, products or systems
may be subsequently redesigned so that they no longer require IXYS' products.
No assurance can be given that IXYS will achieve design wins or that any
design win will result in future revenues. The failure of IXYS to achieve
design wins could materially and adversely affect IXYS' business, financial
condition and results of operations. In addition, there can be no assurance
that IXYS' competitors will not develop new technologies that are
substantially equivalent or superior to IXYS' technologies or that IXYS will
be successful in enhancing existing processes or developing new technologies.
See "IXYS Business--Research and Development" and "--Competition."
 
  Dependence on Key Personnel. IXYS is dependent upon a limited number of key
management, sales and technical personnel. IXYS' future success will depend in
part upon its ability to attract and retain highly qualified personnel. IXYS
faces competition for such personnel from other companies and other
organizations. As a result, there can be no assurance that IXYS will be
successful in hiring or retaining qualified personnel. Subject to the terms of
certain employment agreements, officers and other key personnel could leave
the employ of IXYS with little or no prior notice. Loss of key personnel, such
as Dr. Zommer, Chief Executive Officer, and Mr. Agbayani, Vice President of
Finance and Administration, especially if such loss is without advance notice,
or the inability to hire or retain qualified personnel could have a material
adverse effect on IXYS' business, financial condition and results of
operations. See "IXYS Business--Employees," "--Management" and "Other
Information Regarding IXYS--Employment Contracts" for a description of
employment contracts with certain key employees.
 
  Environmental Regulations. IXYS is subject to a variety of federal, state
and local laws, rules and regulations, and IXYS GmbH is subject to laws, rules
and regulations in Germany, related to the use, storage, handling, discharge
and disposal of certain chemicals and gases used in IXYS' manufacturing
process. Any of those regulations could require IXYS to acquire equipment or
to incur substantial other expenses to comply with environmental regulations.
If substantial additional expenses were incurred by IXYS, product costs could
significantly increase, thus materially adversely affecting IXYS' business,
financial condition and results of operations. IXYS believes that its
activities conform to present environmental regulations. Increasing public
attention has, however, been focused on the environmental impact of
semiconductor operations. While IXYS has not experienced any materially
adverse effects on its operations from environmental regulations, there can be
no assurance that changes in such regulations will not impose the need for
additional capital equipment or other requirements or restrict IXYS' ability
to expand its operations. Although IXYS believes it is currently in compliance
with applicable environmental laws, any failure by IXYS to comply with present
or future environmental laws rules and regulations could result in fines being
imposed on IXYS, suspension of production or cessation of operations, any of
which could have a material adverse effect on IXYS' business, financial
condition and results of operations. IXYS' business, financial condition and
results of operations would be subject to similar effects as a result of
comparable laws and regulations in Germany. See "IXYS Business-- Environmental
Matters."

  IXYS' Lampertheim facility is located in an industrial area in which there
is known environmental contamination. Although IXYS is not aware of any soil
or groundwater contamination at its facility, there can be no assurance that
IXYS' business, financial condition and results of operations will not be
materially adversely affected by this situation.
 
  Potential Volatility of Stock Price. There has been no public market for the
IXYS Common Stock. Although the Combined Company intends to apply to have the
Combined Company's common stock approved for quotation on the Nasdaq SmallCap
Market, there can be no assurance that such approval will be received or that
an active trading market will develop for the Combined Company's common stock
or, if one does develop, that it will be maintained. Factors such as
fluctuation in the Combined Company's operating results, announcements of
technological innovations or new products by the Combined Company or its
competitors and general market conditions may have a significant effect on the
market price of the Combined Company's common stock. In addition, in recent
years the stock market in general, and the market for shares of small
capitalization and high technology stocks in particular, have experienced
extreme price fluctuations, which have often been unrelated to the operating
performance of affected companies.
 
  Financial Exposure to Product Liability Claims. IXYS faces the risk of
financial exposure to product liability claims alleging that the use of
devices which incorporate IXYS' products resulted in adverse effects.
Approximately 5% of IXYS' net revenues in fiscal 1998 were derived from sales
of products used in medical devices. Product liability risks may exist with
respect to these medical devices even with respect to those medical devices
that have received, or in the future may receive, regulatory approval for
commercial sale. See "Effect of Regulations." IXYS does not currently carry
product liability insurance, and there can be no assurance that IXYS will
avoid significant product liability claims. A successful claim brought against
IXYS could have a material adverse effect on IXYS' business, financial
condition and results of operations.
 
  Impact of Year 2000. The Year 2000 will impact computer programs written
using two digits rather than four digits to define the applicable year. Any
programs with time-sensitive software may recognize a date using "00" as the
year 1900 rather than the year 2000. This could result in a system failure or
miscalculations causing disruptions of operation, including a temporary
inability to process transactions, send invoices or engage in other ordinary
activities. This problem largely affects software programs written years ago,
before the issue came to prominence.
 
  IXYS is completing the process of identifying the programs and
infrastructure that could be affected by the Year 2000 issue and has developed
an implementation plan to resolve the issue. The plan includes (i)
implementation of a new management information system intended to address
IXYS' operational functions, including sales, inventory, and engineering
functions, and (ii) the replacement of certain equipment and software with new
equipment and software designed to recognize the turn of the century and
intended to be Year 2000 compliant. The plan is currently expected to result
in non-recurring expenses over the next 1 1/2 years of approximately $750,000
in aggregate. IXYS currently anticipates the implementation plan to be
completed by the end of calendar year 1998.

                 THE MERGER PROPOSAL AND THE ISSUANCE PROPOSAL
 
  This section of the Joint Proxy Statement/Prospectus describes certain
aspects of the Merger. The description does not purport to be complete and is
qualified by reference to the Merger Agreement, which is attached as Annex 1
hereto and is incorporated by reference herein.
 
BACKGROUND
 
  During the summer of 1996, in response to the dramatic changes occurring in
the SRAM industry, the Paradigm Board started to consider and evaluate various
strategic alliances, including possible mergers with companies that could
compliment Paradigm's capabilities. In July 1996, Paradigm retained Alliant
Partners (formerly Bentley Hall Von Gehr International), an investment banking
firm, to explore possible strategic alternatives for Paradigm, including
strategic alliances, mergers and asset sales. From July 1996 to August 1996,
Alliant Partners contacted many semiconductor companies to ascertain their
interest in an acquisition, merger or other strategic relationship with
Paradigm. During that period, Paradigm engaged in discussions with three
companies. None of these discussions resulted in a definitive agreement for a
strategic alliance, a merger with or acquisition of Paradigm.
 
  Due to a variety of business reasons, in the fall of 1996, Paradigm
management decided to sell its wafer fabrication facility and dramatically
reduce fixed costs by transitioning the company into a fabless semiconductor
company. The wafer fabrication facility was sold in November 1996 to Orbit
Semiconductor, Inc.
 
  Through the first part of 1997, Alliant Partners continued to seek strategic
alternatives for Paradigm. In June 1997, Paradigm entered into discussions
with a foreign investment group that expressed an interest in investing in
Paradigm and providing access to strategic alliances with related
semiconductor companies. This interest was discussed at a Paradigm Board
meeting on July 29, 1997. Management was directed to continue negotiations
with this foreign investment group, and detailed due diligence ensued. After a
number of discussions, the foreign investment group decided not to pursue
further negotiations with Paradigm, and in August 1997 discussions between
Paradigm and the foreign investment group ceased.
 
  In September 1997, James Kochman, managing partner and director of Alliant
Partners, introduced Paradigm to IXYS, which had expressed an interest in a
business combination with Paradigm. Alliant Partners had held prior meetings
with IXYS' management and was aware of their interest in a strategic merger
with a small, public semiconductor company. On September 26, 1997, at the
instigation of Mr. Kochman, David Campbell, Chief Financial Officer of
Paradigm, Dr. Nathan Zommer, Chief Executive Officer and President of IXYS,
Arnold Agbayani, Chief Financial Officer and Vice President of IXYS, and
Michael Gulett, Chief Executive Officer and President of Paradigm, met to
discuss the possibility of a business combination of IXYS and Paradigm. On
October 3, 1997, Dr. Zommer, Mr. Agbayani, Howard Slayen of Coopers & Lybrand
L.L.P. ("Coopers"), Charles Cozean, an associate at Alliant Partners, Mr.
Gulett, and Mr. Kochman, convened to discuss further the terms for a possible
business combination, including, among other things, the exchange ratio and
the structure of the transaction.
 
  On October 6, 1997, IXYS management presented to the IXYS Board the
possibility of a business combination with Paradigm. The IXYS Board authorized
IXYS officers and management to continue negotiations and discussions with
Paradigm. The Paradigm management similarly presented its discussions with
IXYS to the Paradigm Board on October 15, 1997. The Paradigm Board authorized
management to continue to negotiate a business combination with IXYS.
 
  On October 7, 1997, Dr. Zommer, Mr. Gulett, and Mr. Agbayani met to discuss
additional details for a possible merger of the two companies, including
financial and personnel issues. During October 1997, management from IXYS and
management from Paradigm visited each other's business sites to conduct due
diligence. During this period, the stock price of Paradigm fluctuated around
$1.25 (prior to the ten-for-one reverse stock split effectuated on May 1,
1998), and the parties discussed the issuance of approximately 120 million
shares by Paradigm to the IXYS stockholders.
 
                                      39
<PAGE>
 
  During the period from September to October 1997, Paradigm management also
had various discussions with two semiconductor memory companies about the
possibility of a merger transaction. Paradigm's discussions with one of the
companies never resulted in any material negotiations regarding transaction
terms. For reasons not known to Paradigm, such company decided not to pursue a
merger transaction with Paradigm after initial discussions between the
parties. Paradigm engaged in negotiations over basic transaction terms with
the other company, and the parties conducted preliminary due diligence on each
other. However, after such preliminary discussions, the other company chose,
as a strategic matter, to complete an initial public offering rather than to
acquire Paradigm.
 
  On October 15, 1997, a draft merger agreement from IXYS was presented to
Paradigm and its advisors. Between October 1 and October 15, 1997, the stock
price of Paradigm was trading between the range of $1.18 to $1.313 (prior to
the ten-for-one reverse stock split effectuated on May 1, 1998), and the
proposed issuance of 120 million shares by Paradigm to the IXYS stockholders
became unacceptable to IXYS. In October 1997, Paradigm proposed a revised
exchange ratio that would provide the IXYS stockholders with a 92% interest in
the Combined Company, with Paradigm stockholders owning the remaining 8% of
the Combined Company. The IXYS management rejected this proposal, and, in
November 1997, after numerous discussions, Paradigm and IXYS elected to cease
negotiations due to a failure to agree on a price.
 
  In early December 1997, Paradigm management entered into discussions with a
foreign semiconductor company about the possibility of an equity investment in
Paradigm combined with a strategic alliance on product development, product
licensing and marketing and sales. Detailed due diligence was conducted by
both parties. A potential agreement to develop a close strategic alliance with
such foreign semiconductor company was presented at a Paradigm Board meeting
on December 12, 1997 and discussed in detail at various Paradigm Board
meetings. In mid-January 1998, such foreign semiconductor company decided to
cease discussions with Paradigm because of the changes in their business due
to the currency crisis in Asia.
 
  On February 2, 1998, Thomas Bentley, a partner at Alliant Partners,
contacted Mr. Agbayani to renew discussions with IXYS regarding a possible
merger transaction and discussed, among other things, the nature of the
consideration that might be paid to the IXYS stockholders. In addition, Mr.
Bentley presented a new potential exchange ratio. Based on the presentation by
Mr. Bentley, Mr. Agbayani agreed to engage in further discussions with
Paradigm.
 
  On February 5, 1998, Mr. Agbayani and Mr. Bentley discussed terms of a
potential business combination. From February 2, 1998 through March 1998,
representatives of IXYS and Paradigm conducted due diligence review of each
other's business, financial, market, technical and other information, material
contracts and other due diligence materials. The senior management of each
company made numerous visits to the other company's facilities. During this
period, the senior management of IXYS and Paradigm had further discussions
regarding the exchange ratio to be applied in the Merger. Because Paradigm's
stock price was trading at approximately $0.50 during this period (prior to
the ten-for-one reverse stock split effectuated on May 1, 1998), Paradigm
proposed a new exchange ratio that would provide the IXYS stockholders a 95%
interest in the Combined Company. Further, Paradigm suggested that an
alternative exchange ratio be used if the shares to be received by the IXYS
stockholders under the first exchange ratio would be valued at less than $150
million. This alternative exchange ratio would guarantee a valuation of the
IXYS Fully Diluted Capitalization at $150 million. IXYS management considered,
but did not agree upon, Paradigm's new proposal at that time.
 
  The Paradigm Board met on February 6, 1998 to review the status of the
proposed Merger with IXYS.
 
  On February 10, 17, 26, and 27, 1998, representatives of IXYS, including
IXYS' legal counsel, met with representatives of Paradigm, including
Paradigm's legal counsel and financial advisor, to discuss the results of the
parties' due diligence investigations, the principal terms of the proposed
Merger and the terms of a draft Merger Agreement, and the severance
arrangements of certain executives of Paradigm.
 
                                      40
<PAGE>
 
  On February 19, 1998, the IXYS Board held a special meeting to consider the
terms, including Paradigm's new proposed exchange ratios, of the proposed
Merger and reviewed with its legal counsel a draft Merger Agreement. Legal
counsel and management also updated the IXYS Board concerning the due
diligence conducted to date. The IXYS Board recommended at that time that
further due diligence be conducted.
 
  On March 5, 1998, the IXYS Board held a special telephonic meeting to
consider the proposed Merger with Paradigm. Members of IXYS' senior management
and IXYS' legal counsel discussed various aspects of the proposed Merger.
Following such discussions, the IXYS Board voted unanimously (i) to approve
the Merger and the Merger Agreement and the related documents for the
transaction as presented to them, and (ii) to recommend that the IXYS
stockholders vote to approve and adopt the Merger Agreement and to approve the
Merger. See "--IXYS' Reasons for the Merger."
 
  On March 5, 1998, the Paradigm Board held a special meeting. At that
meeting, Paradigm's counsel reviewed for the Paradigm Board the proposed
Merger Agreement. Alliant Partners made a financial presentation regarding the
financial terms of the proposed Merger. Alliant Partners' discussion included
a discussion of certain analyses described under "--Opinion of Paradigm's
Financial Advisor." The terms of the Merger Agreement and the Merger were then
discussed among the directors. After these discussions, Alliant Partners
rendered its oral opinion, subsequently confirmed in writing, that the
consideration to be paid in the Merger was fair from a financial point of view
to Paradigm and its stockholders. The Paradigm Board then unanimously voted
(i) to approve the Merger Agreement and the Merger pending resolution of
certain issues and to direct the officers of Paradigm to negotiate the issues
and to finalize the terms of the Merger Agreement and the Merger and (ii) to
recommend that the Paradigm stockholders vote to approve the Issuance
Proposal. See "--Paradigm's Reasons for the Merger."
 
  On March 6, 1998, legal counsel for IXYS and Paradigm and financial advisor
for Paradigm, together with members of management of IXYS and Paradigm,
negotiated and finalized the terms of the Merger Agreement. The Merger
Agreement was executed by all relevant parties after the close of market on
March 6, 1998, and a joint public announcement of the proposed transaction was
made prior to the opening of market on March 9, 1998.
 
PARADIGM'S REASONS FOR THE MERGER
 
  The Paradigm Board considered a wide variety of information and a number of
factors in connection with its evaluation of the proposed Merger and the
Merger Agreement, and determined that the Merger provides an opportunity that
serves the best interests of Paradigm and its stockholders. The Paradigm Board
believes that the Merger may result in a number of benefits to Paradigm and
its stockholders, including, among other benefits, the following:
 
  .  By combining IXYS' capability in power semiconductors and Paradigm's
     capability in high performance integrated circuits, Paradigm and IXYS
     together will have the potential to develop new products with higher
     value that each company would not separately be able to produce.
 
  .  The proposed Merger will help insulate Paradigm from adverse market
     conditions based on current market conditions for SRAMs, the intense
     competition, and lower than desired selling prices, by improving
     Paradigm's cost structure through consolidation and Paradigm's sales
     channels through IXYS' distribution channels in countries where Paradigm
     does not have a strong market presence.
 
  .  Paradigm will be in a better position to sell SRAM products to current
     IXYS customers who are not current Paradigm customers. This will
     therefore, improve Paradigm's opportunity to increase revenue.
 
  .  Paradigm's recent operating results, revenue level and current financial
     condition necessitates additional funding. The proposed Merger will
     provide such funding, which the Paradigm Board believes is a better
     alternative than additional equity financings.
 
                                      41
<PAGE>
 
  In addition to the reasons set forth above, in the course of its
deliberations concerning the Merger, the Paradigm Board consulted with
Paradigm's management, legal counsel and accountants and reviewed a number of
other factors relevant to the Merger, including:
 
  .  Information concerning the business, assets, operations, properties,
     management, financial condition, operating results, competitive position
     and prospects of IXYS and Paradigm.
 
  .  Other alternatives available to Paradigm in the short and long-term to
     achieve Paradigm's funding and other strategic objectives, including the
     availability of public and private financing and a range of business
     combinations.
 
  .  Paradigm's belief that the management styles and corporate cultures of
     the two companies would be complementary.
 
  .  Reports from management and legal counsel concerning the specific terms
     of the Merger Agreement and ancillary documents, including the
     obligation of Paradigm not to solicit or encourage other acquisition
     proposals, the topping fee provisions, the circumstances under which
     either Paradigm or IXYS can terminate the Merger Agreement and the
     closing conditions to the Merger.
 
  The Paradigm Board also considered a number of potentially negative factors
in its deliberations concerning the Merger, including:
 
  .  The possibility of management disruption associated with the Merger and
     the risk that key technical and management personnel of Paradigm or IXYS
     might not continue with the Combined Company.
 
  .  The possibility that the Merger might adversely affect Paradigm's or
     IXYS' relationship with certain of their respective customers.
 
  .  The risk that the potential benefits of the Merger might not be
     realized.
 
  .  The possibility that the Merger might preclude other potential strategic
     transactions by Paradigm.
 
  .  The other risks described above under "Risk Factors."
 
  The Paradigm Board concluded, however, that the benefits of the transaction
to Paradigm and its stockholders outweighed the risks associated with the
foregoing factors.
 
  The foregoing discussion of the information and factors considered by the
Paradigm Board is not intended to be exhaustive but is believed to include all
material factors considered by the Paradigm Board. In view of the wide variety
of factors considered by the Paradigm Board, the Paradigm Board did not find
it practicable to quantify or otherwise assign relative weight to the specific
factors considered. However, after taking into account all of the factors set
forth above, the Paradigm Board unanimously agreed that the Merger Agreement
and the Merger were fair to, and in the best interests of, Paradigm and its
stockholders and that Paradigm should proceed with the Merger.
 
RECOMMENDATION OF THE PARADIGM BOARD
 
  FOR THE REASONS DISCUSSED ABOVE, THE PARADIGM BOARD HAS UNANIMOUSLY APPROVED
THE MERGER AGREEMENT AND THE MERGER AND HAS DETERMINED THAT THE MERGER
AGREEMENT AND THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, PARADIGM
AND THE PARADIGM STOCKHOLDERS. ACCORDINGLY, THE PARADIGM BOARD HAS UNANIMOUSLY
RECOMMENDED THAT THE PARADIGM STOCKHOLDERS VOTE FOR APPROVAL OF THE ISSUANCE
PROPOSAL.
 
PARADIGM VOTE NECESSARY TO APPROVE THE PROPOSAL
 
  Each holder of Paradigm Common Stock is entitled to one vote per share held.
The holders of a majority of the shares of the Paradigm Common Stock issued
and outstanding constitute a quorum. The affirmative vote of holders of a
majority of the outstanding shares of Paradigm Common Stock is required for
approval of the
 
                                      42
<PAGE>
 
Issuance Proposal. In the event that a quorum is not present or represented at
the Paradigm Annual Meeting, the stockholders entitled to vote at the meeting
present in person or by proxy shall have power to adjourn the Paradigm Annual
Meeting until a quorum shall be present or represented. Proxies solicited by
the Paradigm Board will be voted for approval of the Issuance Proposal, unless
otherwise instructed.
 
  A stockholder voting through a proxy who abstains with respect to approval
of the Issuance Proposal shall be considered to have cast a negative vote with
respect to the Issuance Proposal, but shall be treated as present and entitled
to vote on the approval of the Reverse Stock Split Proposal, Increased
Authorization Proposal, Name Proposal, Stock Plan Proposal, Directors Proposal
and Ratification Proposal at the Paradigm Annual Meeting; provided, however,
that a stockholder (including a broker) who does not give authority to a proxy
to vote on the approval of the other proposals shall not be considered present
and entitled to vote on the other proposals.
 
IXYS' REASONS FOR THE MERGER
 
  The IXYS Board has unanimously determined that the Merger Agreement and the
Merger are fair to, and in the best interests of, IXYS and its stockholders.
In reaching its determination, the IXYS Board consulted with IXYS' management,
as well as its consultants, and gave significant consideration to a number of
factors bearing on its decision. The following are reasons why the IXYS Board
believes the Merger will be beneficial to IXYS and its stockholders:
 
  .  The combination of the technologies and product development resources of
     IXYS and Paradigm should enable IXYS to respond more effectively to the
     rapid technological change in, and continuing emergence of, power
     management control products; the technical know-how and design
     capabilities of the designers who design for Paradigm will allow IXYS to
     develop a new line of power management control products.
 
  .  In the Merger, IXYS stockholders will receive securities traded in an
     active trading market, the Nasdaq SmallCap Market, thereby permitting
     the stockholders to obtain liquidity for their investments, in contrast
     to the illiquid nature of their present holdings of IXYS Capital Stock.
 
  .  IXYS currently manufactures and designs various die sizes under 3 to 4
     micron design rules. Paradigm designs and markets die sizes at submicron
     design rules. IXYS believes that the Combined Company's ability to
     operate under a wide spectrum of process technologies, including
     submicron design rules not currently addressed by IXYS, is expected to
     enhance IXYS' ability to service its existing customer base as well as
     to expand into different customer bases.
 
  .  The Merger is expected to provide IXYS with an expanded customer base
     and product development resources to support its current marketing,
     sales and distribution efforts; Paradigm's products are marketed,
     distributed and sold in applications and market segments not currently
     served by IXYS.
 
  .  The Merger will provide IXYS with a publicly traded security to serve as
     a currency for strategic transactions, including acquisitions and
     strategic partnerships.
 
  .  The Merger will result in the Combined Company having an expanded base
     of intellectual property.
 
  In addition to the reasons set forth above, in the course of its
deliberations concerning the Merger, the IXYS Board consulted with IXYS'
management, legal counsel and accountants and reviewed a number of other
factors relevant to the Merger, including:
 
  .  Information concerning the business, assets, operations, properties,
     management, financial condition, operating results, competitive position
     and prospects of IXYS and Paradigm.
 
  .  The historical price and volume trading data for the Paradigm Common
     Stock as well as the composition of Paradigm's stockholder base.
 
  .  Other alternatives available to IXYS in the short and long-term to
     achieve IXYS' funding, liquidity and other strategic objectives,
     including the availability of public and private financing and a range
     of business combinations.
 
                                      43
<PAGE>
 
  .  IXYS' belief that the management styles and corporate cultures of the
     two companies would be complementary.
 
  .  The expectation that the Merger will be tax deferred for federal income
     tax purposes to IXYS' stockholders.
 
  .  Reports from management and legal counsel concerning the specific terms
     of the Merger Agreement and ancillary documents, including the
     obligation of Paradigm not to solicit or encourage other acquisition
     proposals, the topping fee provisions, the circumstances under which
     either Paradigm or IXYS can terminate the Merger Agreement and the
     closing conditions to the Merger.
 
  The IXYS Board also considered a number of potentially negative factors in
its deliberations concerning the Merger, including:
 
  .  The possibility of management disruption associated with the Merger and
     the risk that key technical and management personnel of Paradigm or IXYS
     might not continue with the combined company.
 
  .  The possibility that the Merger might adversely affect Paradigm's or
     IXYS' relationship with certain of their respective customers.
 
  .  The risk that the potential benefits of the Merger might not be
     realized.
 
  .  The possibility that the Merger might preclude other potential strategic
     transactions by IXYS.
 
  .  The other risks described above under "Risk Factors".
 
  The IXYS Board concluded, however, that the benefits of the transaction to
IXYS and its stockholders outweighed the risks associated with the foregoing
factors.
 
  The foregoing discussion of the information and factors considered by the
IXYS Board is not intended to be exhaustive but is believed to include all
material factors considered by the IXYS Board. In view of the wide variety of
factors considered by the IXYS Board, the IXYS Board did not find it
practicable to quantify or otherwise assign relative weight to the specific
factors considered. However, after taking into account all of the factors set
forth above, the IXYS Board unanimously agreed that the Merger Agreement and
the Merger were fair to, and in the best interests of, IXYS and its
stockholders and that IXYS should proceed with the Merger.
 
RECOMMENDATION OF THE IXYS BOARD
 
  FOR THE REASONS DISCUSSED ABOVE, THE IXYS BOARD HAS APPROVED THE MERGER
AGREEMENT AND THE MERGER AND HAS DETERMINED THAT THE MERGER AGREEMENT AND THE
MERGER ARE FAIR TO, AND IN THE BEST INTERESTS OF, IXYS AND THE IXYS
STOCKHOLDERS. ACCORDINGLY, THE IXYS BOARD HAS UNANIMOUSLY RECOMMENDED THAT THE
IXYS STOCKHOLDERS VOTE FOR APPROVAL OF THE MERGER PROPOSAL.
 
IXYS VOTE NECESSARY TO APPROVE THE PROPOSAL
 
  Each holder of IXYS Capital Stock is entitled to one vote per share held.
The holders of a majority of the shares of the IXYS Capital Stock issued and
outstanding constitute a quorum. The affirmative vote of holders of a majority
of the outstanding shares of IXYS Capital Stock entitled to vote, voting
together as a single class and the affirmative vote of holders of a majority
of the outstanding shares of IXYS Preferred Stock entitled to vote, are
required for approval of the Merger Proposal. In the event that a quorum is
not present or represented at the IXYS Special Meeting, the stockholders
entitled to vote at the meeting present in person or by proxy shall have power
to adjourn the IXYS Special Meeting until a quorum shall be present or
represented. Proxies solicited by the IXYS Board will be voted for approval of
the Merger Proposal, unless otherwise instructed.
 
  A stockholder voting through a proxy who abstains with respect to approval
of the Merger Proposal shall be considered to have cast a negative vote with
respect to the Merger Proposal, but shall be treated as present and entitled
to vote on the approval of the IXYS Certificate Proposal at the IXYS Special
Meeting; provided,
 
                                      44

however, that a stockholder (including a broker) who does not give authority
to a proxy to vote on the approval of the other proposals shall not be
considered present and entitled to vote on the other proposal.
 
OPINION OF FINANCIAL ADVISOR TO PARADIGM
 
  Paradigm retained Alliant Partners, an investment banking firm which
performed investment banking services for Paradigm during fiscal 1997, to
render a fairness opinion letter in connection with the Merger. Alliant
Partners was selected by the Paradigm Board to provide a written opinion (the
"Alliant Partners Opinion") based on Alliant Partners' qualifications,
expertise and reputation.
 
  Paradigm engaged Alliant Partners to act as its financial advisor to render
an opinion as to the fairness, from a financial point of view, to Paradigm
stockholders of the consideration to be paid for IXYS in connection with the
Merger. Alliant Partners rendered its oral opinion, subsequently confirmed in
writing, on March 5, 1998, to the Paradigm Board that, as of such date, the
consideration to be paid by Paradigm pursuant to the Merger Agreement is fair
to Paradigm's stockholders, from a financial point of view. No limitations
were placed on Alliant Partners by the Paradigm Board with respect to the
investigation made or the procedures followed in preparing and rendering its
opinion.
 
  In its review of the Merger, and in arriving at its opinion, Alliant
Partners, among other things: (i) reviewed the financial statements of IXYS
for recent years, interim periods to date, projections for future years and
certain other relevant financial and operating data of IXYS made available to
Alliant Partners; (ii) discussed with certain members of the management of
Paradigm and IXYS, the business, financial condition and prospects of IXYS;
(iii) reviewed and discussed with management of Paradigm and IXYS the
strategic rationale for, and the potential benefits of, the Merger; (iv)
reviewed the recent reported prices and trading activity and compared certain
financial information of other companies engaged in businesses which Alliant
Partners considered comparable to those of IXYS; (v) reviewed the financial
terms, to the extent publicly available, of certain comparable merger and
acquisition transactions; (vi) reviewed the projected financial statements and
projected cash flows of IXYS in a discounted cash flow analysis; (vii)
analyzed the relative contribution each company would make to the proposed
Combined Company's financial statements; (viii) examined Paradigm's financial
position, their plans and their ability to operate as a going concern; (ix)
reviewed the Merger Agreement; (x) discussed the tax and accounting treatment
of the Merger with IXYS' management and IXYS' consultants; and (xi) performed
such other analyses and examinations and considered such other information,
financial studies, analyses and investigations and financial, economic and
market data as Alliant Partners deemed relevant.
 
  Alliant Partners did not independently verify any of the information
concerning IXYS considered in connection with their review of the Merger and,
for purposes of its opinion, Alliant Partners assumed and relied upon the
accuracy and completeness of all such information. In connection with its
opinion, Alliant Partners did not prepare or obtain any independent evaluation
or appraisal of any of the assets or liabilities of IXYS. For purposes of
their opinion, Alliant Partners assumed that the Merger would qualify as a
tax-free reorganization for the stockholders of IXYS and that the Merger would
be accounted for as a purchase accounting transaction. Alliant Partners'
opinion is necessarily based upon market, economic, financial and other
conditions as they exist and can be evaluated as of the date of the opinion
and any subsequent change in such conditions would require a reevaluation of
such opinion.
 
  The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. The
summary of the Alliant Partners analyses set forth below does not purport to
be a complete description of the presentation by Alliant Partners to the
Paradigm Board. Accordingly, Alliant Partners believes that its analyses and
the summary set forth below must be considered as a whole. Selecting portions
of its analyses, without considering all factors and analyses, could create an
incomplete view of the processes underlying the analyses set forth in the
Alliant Partners presentation to the Paradigm Board and its opinion. In
performing its analyses, Alliant Partners made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of IXYS. The analyses
performed by Alliant Partners (and summarized below) are not necessarily
indicative of
 
                                      45
<PAGE>
 
actual values beyond these specific facts on this date or of actual future
results, which may be significantly more or less favorable than suggested by
such analyses.
 
  The following is a brief summary of material financial analyses performed by
Alliant Partners in connection with providing its written opinion to the
Paradigm Board dated March 5, 1998:
 
  Valuation Summary. Based upon the financial information provided to Alliant
Partners, the financial performance of IXYS and Paradigm, and the current
semiconductor market conditions, Alliant Partners rendered its opinion that
the value of IXYS, from a financial point of view, is $167 million, with the
range between $142 million and $192 million. The value of the consideration to
be paid for IXYS, calculated as $177 million at the time the fairness opinion
was rendered, is within in the range Alliant Partners determined to be fair
from a financial point of view.
 
  The valuation for IXYS was derived from a weighted average calculation of
four valuation methodologies: Relative Contribution, Public Market
Comparables, Related Industry M&A Transactions, and Discounted Cash Flow (see
below for results of each method).
 
  The Relative Contribution and the Public Market Comparables methodologies
were weighted at 40% each because Alliant Partners believed these
methodologies were significantly more relevant than the Related Industry M&A
Transactions and Discounted Cash Flow. The Relative Contribution methodology
evaluates IXYS' direct contribution to the Combined Company while the Public
Market Comparables methodology evaluates current market value of semiconductor
companies as a going concern.
 
  The Related Industry M&A Transactions methodology was weighted at 10%
because the transactions in the M&A population were mostly accounted for as
pooling of interest transactions while the Paradigm and IXYS transaction was
accounted for as purchase accounting. The transaction accounting method
generally has an impact on the acquiror's decision regarding the amount of
consideration to be paid in a merger or acquisition. Higher prices may be paid
in pooling transactions because the acquiror is not required to recognize
goodwill that could, in the short term, dilute the acquiror's earnings per
share. The Discounted Cash Flow methodology was weighted at 10% because such
methodology derives its value from uncertain future projections and not on
historical results. In this transaction, historical results played a
significant role in valuation.
 
  Public Market Comparables. Alliant Partners reviewed and compared selected
historical and projected financial information of IXYS corresponding financial
information and ratios of publicly traded companies which Alliant Partners
deemed to be comparable in many respects to IXYS. Such data and ratios
included the market value, revenue, net earnings, cash and debt of each
company. The Public Market Comparables were companies which manufactured
memory semiconductor products or personal computer semiconductor products.
Companies used as public comparables included International Rectifier, Linear
Technology, Micrel, Microsemi, Siliconix, Supertex, Telcom Semiconductor, and
Unitrode. Alliant Partners used the average of the comparables' last twelve
months revenue multiples and the average of the comparables' last twelve
months earnings multiples to determine the value of IXYS. Alliant Partners
analyzed the projected operating performance of IXYS, compared it to the last
twelve month operating performance of the comparable companies, and made
appropriate adjustments to the last twelve months revenue and earnings
multiples. Alliant Partners utilized the financial projections for IXYS's
fiscal year ending March 31, 1998 multiplied by the adjusted average of the
comparable companies' last twelve months revenue and earnings multiples. The
public market comparables valuation was $165 million, with a range between
$140 million and $190 million.
 
  Related Industry Transactions. Alliant Partners compared the proposed merger
with selected comparable completed merger and acquisition transactions. In the
population of merger and acquisition transactions, the companies manufactured
memory semiconductor products or personal computer semiconductor products.
These transactions included: Benchmarq Microelectronics acquired by Unitrode,
BKC Semiconductors acquired by Microsemi, Raytheon Semiconductor acquired by
Fairchild Semiconductor, Edge Semiconductor acquired by Semtech, Chips &
Technologies acquired by Intel, Cyrix acquired by National Semiconductor, and
Lite-On
 
                                      46
<PAGE>
 
Power Semiconductor acquired by Vishay International. This analysis of the
selected transactions derived an average for the consideration paid as a
multiple of latest twelve month revenues and an average for the consideration
paid as a multiple of earnings. Alliant Partners utilized the financial
projections for IXYS' fiscal year ending March 31, 1998 multiplied by the
average of the merger and acquisition transactions revenues and earnings
multiples. The related industry transaction valuation was $125 million with a
range between $106 million and $143 million.
 
  Discounted Cash Flow. Alliant Partners analyzed IXYS based on a discounted
cash flow analysis of the projected financial performance of IXYS. The
discounted cash flow analysis determined the after-tax cash flows generated
through IXYS' fiscal year of 2000. Alliant Partners used three years of
projected financial statements for IXYS, provided by the management of IXYS,
derived the after-tax cash flows, and discounted the cash flows using a
discount rate appropriate for a company with performance, technological,
manufacturing, and operational risks similar to IXYS. The final discounted
cash flow also included a terminal value reflecting the value of the business
at the end of year three. The discounted cash flow valuation was $175 million
with a range between $149 million and $201 million.
 
  Relative Contribution. Alliant Partners utilized a comparative analysis of
IXYS' and Paradigm's financial contribution in relation to the total
financials of the proposed combined company. The relative contribution
analysis includes an income statement contribution analysis. In addition, the
relative contribution analysis includes a balance sheet contribution analysis.
The income statement and balance sheet relative contribution analysis were
then averaged to determine the final overall relative contribution. The
relative contribution valuation was $177 million with a range between $151
million and $204 million.
 
  Alliant Partners, as part of its investment banking business, is regularly
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, corporate restructurings, corporate partnerings and
strategic alliances.
 
  Pursuant to the terms of an engagement letter by and between Paradigm and
Alliant Partners, dated December 2, 1996, and a subsequent letter agreement
dated January 13, 1998, Paradigm has agreed to pay Alliant Partners a
transaction fee of $225,000, upon consummation of the Merger, and an
additional $100,000 for rendering the Alliant Partners Opinion. Paradigm has
also agreed to reimburse Alliant Partners for certain of its reasonable out-
of-pocket expenses and to indemnify it against certain liabilities relating to
or arising out of services performed by Alliant Partners as financial advisor
to Paradigm.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  Officers and Directors of Paradigm. Certain members of Paradigm's management
and Board of Directors may be deemed to have certain interests in the Merger
that are in addition to their interests as stockholders of Paradigm generally.
The interest of Paradigm's management and the Paradigm Board are as described
in""--Employment/Severance Arrangement" and "Other Information Regarding
Paradigm--Certain Relationships and Related Transactions." Other than as set
forth in "--Employment/Severance Arrangement" and "Other Information Regarding
Paradigm--Certain Relationships and Related Transactions" and "Security
Ownership of Certain Beneficial Owners and Management of Paradigm," no other
benefit will be received by the Paradigm executive officers and directors. The
Paradigm Board was aware of these interests and considered them, among other
matters, in approving the Merger Agreement and the transactions contemplated
thereby.
 
  Indemnification and Insurance. The Merger Agreement provides that all rights
to indemnification existing in favor of the persons serving as directors and
officers of Paradigm as of the date of the Merger Agreement for acts or
omissions occurring prior to the Effective Time, as provided in Paradigm's
Certificate of Incorporation and Bylaws and in certain indemnification
agreements between Paradigm and such directors and officers, will survive the
Merger, and that Paradigm will cause the Surviving Corporation to perform its
obligations arising thereunder for at least six years from the Effective Time.
Subject to certain limitations, Paradigm has also agreed to cause the Combined
Company to maintain in effect for three years after the Effective Time the
policy of
 
                                      47
<PAGE>
 
directors' and officers' liability insurance in existence at the date of the
Merger Agreement for the benefit of persons serving as directors and officers
of Paradigm as of such date. Such limitations include the fact that the
Combined Company shall not be required to maintain the directors' and
officers' liability insurance in existence as of the date of the Merger
Agreement if equivalent coverage is provided to such directors and officers
under another policy of directors' and officers' liability insurance. Further,
if coverage is provided to such persons under another policy of officers' and
directors' liability insurance,  the Combined Company shall not be required to
expend in any one year an amount in excess of 150% of the annual premium
currently paid by Paradigm for such insurance, and if the annual premiums of
such insurance coverage exceed 150% of the annual premium currently paid by
Paradigm for such insurance, the Combined Company shall be obligated to obtain
a policy with the greatest coverage available for a cost not exceeding such
amount. See "The Merger Agreement--Indemnification and Insurance."
 
  Employment/Severance Arrangement. Each of Messrs. Campbell and Morley have
entered into Executive Compensation Agreements with Paradigm which provide
that if the Executive's employment with the Combined Company is terminated
without "cause" within six months following the Effective Time, such Executive
would be paid, in a single lump sum payment, two months of salary at the rate
in effect on the date of the Executive Compensation Agreement. Messrs.
Campbell and Morley are entitled to two months of annual base salary for an
aggregate of $10,834 and $25,000, respectively, if they are terminated without
"cause" within six months of the Effective Time.
 
  Election as Director. Pursuant to the Merger Agreement, Mr. Kochman, who is
currently a director of Paradigm, will be nominated as a management nominee
for election to the Paradigm Board and shall remain as a director of the
Combined Company after the Merger. Mr. Kochman is also a managing partner and
director of Alliant Partners. However, Mr. Kochman will not derive any
economic benefit from Alliant Partners' representation of Paradigm in
connection with the Merger.
 
  Officers and Directors of IXYS. Certain members of IXYS' management and
Board of Directors may be deemed to have certain interests in the Merger that
are in addition to their interests as stockholders of IXYS generally. The IXYS
Board was aware of these interests and considered them, among other matters,
in approving the Merger Agreement and the transactions contemplated thereby.
At the Effective Time, Dr. Zommer, Mr. Agbayani and Dr. Karg will be appointed
to the board of directors of the Combined Company. It is currently expected
that the executive officers of IXYS will serve after the Effective Time as the
executive officers of the Combined Company. In addition to the benefits
described below, the officers and directors of IXYS will benefit on the same
basis with respect to their stock and option holdings of IXYS as other holders
of IXYS Capital Stock and options exercisable for IXYS Common Stock. See
"Security Ownership of Certain Beneficial Owners and Management of IXYS."
 
  Indemnification and Insurance. The Merger Agreement provides that Paradigm
will cause the Surviving Corporation to perform its obligations arising under
IXYS' Certificate of Incorporation and Bylaws for at least six years from the
Effective Time. Subject to certain limitations, Paradigm has also agreed to
cause the Combined Company to maintain in effect for three years after the
Effective Time the policy of directors' and officers' liability insurance in
existence at the date of the Merger Agreement for the benefit of persons
serving as directors and officers of Paradigm as of such date. Such
limitations include the fact that the Combined Company shall not be required
to maintain the directors' and officers' liability insurance in existence as
of the date of the Merger Agreement if equivalent coverage is provided to such
directors and officers under another policy of directors' and officers'
liability insurance. Further, if coverage is provided to such persons under
another policy of officers' and directors' liability insurance, the Combined
Company shall not be required to expend in any one year an amount in excess of
150% of the annual premium currently paid by Paradigm for such insurance, and
if the annual premiums of such insurance coverage exceed 150% of the annual
premium currently paid by Paradigm for such insurance, the Combined Company
shall be obligated to obtain a policy with the greatest coverage available for
a cost not exceeding such amount. See "The Merger Agreement--Indemnification
and Insurance."

  Registration Rights Agreement. As a condition to the consummation of the
Merger, two of IXYS' principal stockholders, ABB, Inc. and ABB AG
(collectively "ABB"), shall enter into the Registration Rights Agreement with
Paradigm on or prior to the Effective Time. Dr. Karg is an officer of ABB AG
and a director of IXYS. Pursuant to the Registration Rights Agreement, ABB
will be entitled to certain rights with respect to registration of the
Paradigm Common Stock it receives pursuant to the Merger (the "Merger Shares")
under the Securities Act. If the Combined Company proposes to register any of
its securities under the Securities Act, either for its own account or for the
account of other security holders after the Effective Time (the "Company
Registration"), ABB will be entitled to notice of the registration and will be
entitled to include the Merger Shares therein, except, among other conditions,
that (i) the underwriters have the right to limit the number of such Merger
Shares included in the Company Registration, and (ii) except with respect to
any one offering after the first Company Registration, in no event may the
underwriters reduce the securities of ABB included in the Company Registration
below 25% of the total amount of securities in the offering. In addition, ABB
may require the Combined Company to file a registration statement under the
Securities Act with respect to its Merger Shares, and the Combined Company
would be required to use its reasonable best efforts to effect the
registration, subject to certain restrictions and limitations. Further, under
the Registration Rights Agreement, ABB may require the Combined Company to
register its shares on Form S-3 when such form is available to the Combined
Company, subject to certain conditions and limitations. The Registration
Rights Agreement also provides ABB with certain inspection rights and rights
to attend Board of Directors meetings of the Combined Company provided that,
at the time of such board meetings, ABB holds more than 10% of the outstanding
shares of common stock of the Combined Company.
 
VOTING AGREEMENT
 
  Pursuant to the Voting Agreement, Dr. Zommer, who owned in the aggregate
issued and outstanding shares of IXYS Capital Stock representing approximately
30.90% of the shares of IXYS Capital Stock issued and outstanding as of the
IXYS Record Date, has agreed that, prior to the Expiration Date, he will vote
his shares of IXYS Common Stock in favor of: (i) the Merger; (ii) the
execution and delivery by IXYS of the Merger Agreement; (iii) the adoption and
approval of the terms of the Merger Agreement; and (iv) each of the other
actions contemplated by the Merger Agreement and any action required in
furtherance thereof. Dr. Zommer has also delivered to Paradigm an irrevocable
proxy with respect to the matters covered by the Voting Agreement. In
addition, subject to certain exceptions, Dr. Zommer has agreed not to transfer
any IXYS Capital Stock owned by him unless and until the proposed transferee
of such IXYS Capital Stock shall have (i) executed a counterpart of the Voting
Agreement and the corresponding irrevocable proxy and (ii) agreed to hold such
IXYS Capital Stock subject to all of the terms and conditions of the Voting
Agreement.
 
AFFILIATE AGREEMENTS
 
  Under the Merger Agreement, IXYS will deliver to Paradigm an agreement
executed by each person who could reasonably be determined to be an
"affiliate" of IXYS, as such term is defined in Rule 145 promulgated under the
Securities Act (an "Affiliate"), that generally requires such person, for the
one year period following consummation of the Merger, to sell shares to the
public only in accordance with the volume restrictions and manner of sale
restrictions of Rule 144. These restrictions generally require that sales to
the public be made only through unsolicited "brokers' transactions" or in
transactions directly with a "market maker," as such terms are defined in Rule
144. Additionally, the number of shares to be sold by an Affiliate (together
with certain related persons and certain persons acting in concert) within any
three-month period for purposes of Rule 145 may not exceed the greater of 1%
of the outstanding shares of common stock of the Combined Company or the
average weekly trading volume of such stock during the four calendar weeks
preceding such sale. One year after the Effective Time, an Affiliate would be
able to sell such common stock of the Combined Company without such sale or
volume limitations provided that the Combined Company was current with its
Exchange Act informational filings and such Affiliate was not then an
Affiliate of the Combined Company. This requirement will lapse if the SEC
repeals the provisions currently contained in Rule 145(c) in a manner that
would apply to this transaction.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
  The following discussion summarizes the material federal income tax
considerations of the Merger that are generally applicable to holders of IXYS
Capital Stock. This discussion assumes that holders of shares of IXYS Capital
Stock hold such shares as capital assets. This discussion is based on
currently existing provisions of the Code, existing Treasury Regulations
thereunder and current administrative rulings and court decisions, all of
which are subject to change. Any such change, which may or may not be
retroactive, could alter the tax consequences to the IXYS stockholders.
 
  IXYS stockholders should be aware that this discussion does not deal with
all federal income tax considerations that may be relevant to particular IXYS
stockholders in light of their particular circumstances, such as stockholders
who are dealers in securities, banks, insurance companies or tax-exempt
organizations, who are subject to the alternative minimum tax provisions of
the Code, who are non-United States persons, who acquired their shares in
connection with stock option or stock purchase plans or in other compensatory
transactions or who hold their shares as a hedge or as part of a hedging,
straddle, conversion or other risk reduction transaction. In addition, the
following discussion does not address the tax consequences of the Merger under
foreign, state or local tax laws or the tax consequences of transactions
effectuated prior to or after the Merger (whether or not such transactions are
in connection with the Merger).
 
  It is the opinion of Cooley Godward LLP ("Cooley Godward"), counsel to IXYS,
and Pillsbury Madison & Sutro LLP ("Pillsbury"), counsel to Paradigm, that the
Merger will constitute a reorganization (a "Reorganization") pursuant to
Section 368(a) of the Code (collectively, the "Tax Opinions"). In addition,
IXYS' obligation to consummate the Merger is conditioned on the receipt by
IXYS of an opinion from Cooley Godward, confirming that the Merger will
constitute a Reorganization (the "Closing Opinion"). Such condition will not
be waived without a resolicitation of the IXYS' stockholders' consent. Cooley
Godward has advised IXYS that it currently expects to be able to deliver such
Closing Opinion. See "The Merger Agreement--Conditions to of the Merger--IXYS'
Conditions." The Tax Opinions and Closing Opinion (i) will not be binding on
the Internal Revenue Service (the "IRS") nor preclude the IRS from adopting a
contrary position, (ii) will be based on the assumptions discussed below, as
well as representations received from Paradigm, Merger Subsidiary and IXYS,
(iii) will be based on the assumption that the Merger will be consummated in
accordance with the terms of the Merger Agreement and (iv) will be subject to
the limitations discussed below. Neither Paradigm nor IXYS has requested, or
will request, a ruling from the IRS with regard to any of the federal income
tax consequences of the Merger. The Tax Opinions and Closing Opinion assume
and are conditioned upon (i) the truth and accuracy of the statements,
covenants, representations and warranties contained in the Merger Agreement,
in the representations received from Paradigm, Merger Subsidiary and IXYS to
support the Tax Opinions and Closing Opinion (the "Tax Representations") and
in all other instruments and documents related to the formation, organization
and operation of Paradigm, Merger Subsidiary and IXYS examined by and relied
upon by Cooley Godward and Pillsbury in connection with the Merger; (ii) that
original documents submitted to such counsel are authentic, documents
submitted to such counsel as copies conform to the original documents, and
that all such documents have been (or will be by the Effective Time) duly and
validly executed and delivered where due execution and delivery are a
prerequisite to the effectiveness thereof; (iii) that all covenants contained
in the Merger Agreement and in the Tax Representations are performed without
waiver or breach of any material provision thereof; and (iv) that any
representation or statement made "to the best of knowledge" or similarly
qualified is correct without such qualification.
 
  Subject to the limitations and qualifications referred to herein and in the
Tax Opinions and Closing Opinion, it is the opinion of Cooley Godward and
Pillsbury that as a result of the Merger's qualifying as a Reorganization, the
following U.S. federal income tax consequences will result:
 
  .  No gain or loss will be recognized for federal income tax purposes by
     the holders of IXYS Capital Stock upon the receipt of common stock of
     the Combined Company solely in exchange for such IXYS Capital Stock in
     the Merger (except to the extent that cash is received in lieu of
     fractional shares).
 
                                      50
<PAGE>
 
  .  The aggregate tax basis of the common stock of the Combined Company so
     received by IXYS stockholders in the Merger (including any fractional
     shares of common stock of the Combined Company not actually received)
     will be the same as the aggregate tax basis of the IXYS Capital Stock
     surrendered in exchange therefor.
 
  .  The holding period of the common stock of the Combined Company so
     received by each IXYS stockholder in the Merger will include the holding
     period of the shares of IXYS Capital Stock surrendered in exchange
     therefor.
 
  .  Cash payments received by holders of IXYS Capital Stock in lieu of
     fractional shares of common stock of the Combined Company will be
     treated as if such fractional shares had been issued in the Merger and
     then redeemed by Paradigm. An IXYS stockholder receiving such cash will
     recognize gain or loss upon such payment, measured by the difference (if
     any) between the amount of cash received and the basis allocated to such
     fractional share. The gain or loss should be capital gain or loss,
     provided that each such fractional share of common stock of the Combined
     Company was held as a capital asset at the Effective Time of the Merger.
 
  .  A holder of IXYS Capital Stock who exercises appraisal rights with
     respect to a share of IXYS Capital Stock and receives a cash payment for
     such shares generally should recognize capital gain or loss measured by
     the difference between the stockholder's basis in such share and the
     amount of cash received, provided that such payment is not "essentially
     equivalent to a dividend" within the meaning of Section 302 of the Code
     nor has the effect of a distribution of a dividend within the meaning of
     Section 356(a)(2) of the Code after giving effect to the constructive
     ownership rules of the Code (collectively, a "Dividend Equivalent
     Transaction"). A sale of shares pursuant to an exercise of appraisal
     rights generally will not be a Dividend Equivalent Transaction if, as a
     result of such exercise, the stockholder exercising the appraisal rights
     owns no shares of capital stock of the Combined Company (either actually
     or constructively within the meaning of Section 318 of the Code)
     immediately after the Merger.
 
  A successful IRS challenge to the Reorganization status of the Merger could
result in significant adverse tax consequences to IXYS stockholders. An IXYS
stockholder would recognize gain or loss with respect to each share of IXYS
Capital Stock surrendered equal to the difference between the stockholder's
basis in such share and the fair market value, as of the Effective Time, of
the common stock of the Combined Company received in exchange therefor. In
such event, a stockholder's aggregate basis in the common stock of the
Combined Company so received would equal its fair market value, and the
stockholder's holding period for such stock would begin the day after the
Merger is consummated.
 
  Even if the Merger qualifies as a Reorganization, a recipient of common
stock of the Combined Company would recognize income to the extent that, for
example, any such shares were determined to have been received in exchange for
services, to satisfy obligations or in consideration for anything other than
the IXYS Capital Stock surrendered. In addition, to the extent that an IXYS
stockholder were treated as receiving (directly or indirectly) consideration
other than common stock of the Combined Company in exchange for such
stockholder's IXYS Capital Stock, gain, if any, would have to be recognized.
 
  Certain noncorporate IXYS stockholders may be subject to backup withholding
at a rate of 31% on cash payments received in lieu of a fractional share
interest in common stock of the Combined Company. Backup withholding will not
apply, however, to a stockholder who furnishes a correct taxpayer
identification number ("TIN") and certifies that he, she or it is not subject
to backup withholding on the substitute Form W-9 included in the Letter of
Transmittal, who provides a certificate of foreign status on Form W-8, or who
is otherwise exempt from backup withholding. A stockholder who fails to
provide the correct TIN on Form W-9 may be subject to a $50 penalty imposed by
the IRS.
 
  Each IXYS stockholder will be required to retain records and file with such
holder's U.S. federal income tax return a statement setting forth certain
facts relating to the Merger.

  THE PRECEDING DISCUSSION DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR
DISCUSSION OF ALL POTENTIAL TAX EFFECTS RELEVANT TO THE MERGER. THUS, HOLDERS
OF IXYS CAPITAL STOCK ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING TAX RETURN
REPORTING REQUIREMENTS, THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL
AND OTHER APPLICABLE TAX LAWS AND THE EFFECTS OF ANY PROPOSED CHANGES IN THE
TAX LAWS.
 
ANTICIPATED ACCOUNTING TREATMENT
 
  In the proposed transaction, Paradigm will be acquiring all of the
outstanding shares of IXYS stock and the combination will be accounted for
under the purchase method of accounting. However, for financial accounting
purposes the transaction will be accounted for as a "reverse merger" and IXYS'
historical financial statements will be the financial statements of the post-
merger Combined Company. Under the purchase method of accounting, Paradigm's
results of operations will be combined with those of IXYS from and after the
Effective Time, and Paradigm's specific tangible and identifiable intangible
assets and liabilities will be recorded in IXYS' financial statements at their
respective fair values at the Effective Time. The excess of the purchase price
over the fair value of Paradigm's specific tangible and identifiable
intangible assets and liabilities will be recorded as goodwill and amortized
over a period not expected to exceed three years. The fiscal year end of the
Combined Company will be March 31.
 
REGULATORY MATTERS
 
  Paradigm and IXYS are not aware of any governmental or regulatory
requirements relating to the consummation of the Merger, other than compliance
with the HSR Act. Under the HSR Act and the rules promulgated thereunder by
the FTC, the Merger may not be consummated until notifications have been given
and certain information has been furnished to the FTC and the Antitrust
Division and specified waiting period requirements have been satisfied or
early termination of the waiting period is granted at the request of Paradigm
and IXYS. On May 13, 1998, Paradigm and ABB filed notification and report
forms under the HSR Act with the FTC and the Antitrust Division. They have
subsequently received a notice of early termination of such waiting period
from the FTC.
 
RIGHTS OF APPRAISAL
 
  If the Merger is consummated, stockholders of IXYS who make the demand
described below with respect to their shares, who continuously are the record
holders of such shares through the Effective Time, who otherwise comply with
the statutory requirements of Section 262 of the DGCL (a copy of which Section
is attached as Annex C to this Joint Proxy Statement/Prospectus) and who
neither vote in favor of the Merger Agreement nor consent thereto in writing
will be entitled to an appraisal by the Delaware Court of Chancery (the
"Delaware Court") of the fair value of their shares of IXYS Capital Stock.
Except as set forth herein, stockholders of IXYS will not be entitled to
appraisal rights in connection with the Merger. Holders of Paradigm Common
Stock do not have rights of appraisal under Section 262 in connection with the
Merger because Paradigm is not a constituent corporation in the Merger.
 
  A holder of shares of IXYS Capital Stock wishing to exercise dissenters'
rights of appraisal must, before the taking of the vote on the Merger at the
IXYS Special Meeting, deliver to IXYS a written demand for appraisal of such
shares. A demand for appraisal will be sufficient if it reasonably informs
IXYS of the identity of the stockholder and that the stockholder intends
thereby to demand the appraisal of his or her shares. A proxy or vote against
the Merger shall not constitute such a demand. A failure to vote against the
Merger shall not constitute waiver of appraisal rights.
 
  Within 10 days after the Effective Time, the Surviving Corporation shall
notify each stockholder of IXYS who has satisfied the foregoing conditions and
not voted in favor of the Merger as of the date on which the
 
                                      52
<PAGE>
 
Merger became effective. Within 120 days after the Effective Time, either the
Surviving Corporation or any stockholder who has complied with the required
conditions of Section 262 may file a petition in the Delaware Court, with a
copy served on the Surviving Corporation in the case of a petition filed by a
stockholder, demanding a determination of the fair value of the shares of all
dissenting stockholders. There is no present intent on the part of the
Surviving Corporation to file an appraisal petition and stockholders seeking
to exercise appraisal rights should not assume that the Surviving Corporation
will file such a petition or that the Surviving Corporation will initiate any
negotiations with respect to the fair value of such shares. Accordingly,
stockholders who desire to have their shares appraised should initiate any
petitions necessary for the perfection of their appraisal rights within the
time periods and in the manner prescribed in Section 262. Within 120 days
after the Effective Time, any stockholder who has theretofore complied with
the applicable provisions of Section 262 will be entitled, upon written
request, to receive from the Surviving Corporation, a statement setting forth
the aggregate number of shares of IXYS Capital Stock not voted in favor of the
Merger and the number of shares of IXYS Capital Stock with respect to which
demands for appraisal have been received by IXYS and the aggregate number of
holders of such shares. Such statement must be mailed within 10 days after the
written request therefor has been received by the Surviving Corporation or
within 10 days after expiration of the period for the delivery of demands for
appraisal, whichever is later.
 
  If a petition for an appraisal is timely filed, at the hearing on such
petition, the Delaware Court will determine which stockholders are entitled to
appraisal rights. The Delaware Court may require the stockholders who have
demanded an appraisal for their shares and who hold stock represented by
certificates to submit their certificates of stock to the Register in Chancery
for notation thereon of the pendency of the appraisal proceedings; and if any
stockholder fails to comply with such direction, the Delaware Court may
dismiss the proceedings as to such stockholder. Where proceedings are not
dismissed, the Delaware Court will appraise the shares of IXYS Capital Stock
owned by such stockholders, determining the fair value of such shares
exclusive of any element of value arising from the accomplishment or
expectation of the Merger, together with a fair rate of interest, if any, to
be paid upon the amount determined to be the fair value. In determining fair
value, the Delaware Court is to take into account all relevant factors. In
Weinberger v. UOP Inc., the Delaware Supreme Court discussed the factors that
could be considered in determining fair value in an appraisal proceeding,
stating that "proof of value by any techniques or methods which are generally
considered acceptable in the financial community and otherwise admissible in
court" should be considered, and that "fair price obviously requires
consideration of all relevant factors involving the value of a company." The
Delaware Supreme Court stated that in making this determination of fair value
the court must consider market value, asset value, dividends, earnings
prospects, the nature of the enterprise and any other facts which could be
ascertained as of the date of the merger which throw light on future prospects
of the merged corporation. In Weinberger, the Delaware Supreme Court stated
that "elements of future value, including the nature of the enterprise, which
are known or susceptible of proof as of the date of the merger and not the
product of speculation, may be considered." However, the court noted that, in
determining fair value under Section 262, "the speculative elements of value
that may arise from the "accomplishment' or "expectation' of the merger are
excluded."
 
  Holders of shares of IXYS Capital Stock considering seeking appraisal should
recognize that the fair value of their shares determined under Section 262
could be more than, the same as or less than the consideration they are
entitled to receive pursuant to the Merger Agreement if they do not seek
appraisal of their shares. The cost of the appraisal proceeding may be
determined by the Delaware Court and taxed against the parties as the Delaware
Court deems equitable in the circumstances. Upon application of a dissenting
stockholder of IXYS, the Delaware Court may order that all or a portion of the
expenses incurred by any dissenting stockholder in connection with the
appraisal proceeding, including without limitation, reasonable attorney's fees
and the fees and expenses of experts, be charged pro rata against the value of
all shares of stock entitled to appraisal.
 
  From and after the Effective Time, no stockholder who has demanded appraisal
rights in compliance with the requirements of Section 262 of the DGCL will be
entitled to vote such stock for any purpose or to receive payment of dividends
or other distributions on the stock (except dividends or other distributions
that were payable to record holders prior to the Effective Time).
 
                                      53
<PAGE>
 
  At any time within 60 days after the Effective Time, any stockholder will
have the right to withdraw such demand for appraisal and to accept the terms
offered in the Merger; after this period, the stockholder may withdraw such
demand for appraisal only with the consent of the Surviving Corporation. If no
petition for appraisal is filed with the Delaware Court within 120 days after
the Effective Time, stockholders' rights to appraisal will cease, and all
holders of shares of IXYS Capital Stock will be entitled to receive the
consideration offered pursuant to the Merger Agreement. Inasmuch as the
Surviving Corporation has no obligation to file such a petition, and the
Surviving Corporation has no present intention to do so, any holder of shares
of IXYS Capital Stock who desires such a petition to be filed is advised to
file it on a timely basis. No petition timely filed in the Delaware Court of
Chancery demanding appraisal shall be dismissed as to any stockholder without
the approval of the Delaware Court, and such approval may be conditioned upon
such terms as the Delaware Court deems just.
 
  The foregoing is only a summary of Section 262, and is qualified in its
entirety by reference to the provisions thereof, the full text of which is set
forth as Annex C to this Joint Proxy Statement/Prospectus. Each stockholder of
IXYS is urged to read carefully the full text of Section 262.
 
NO PARADIGM APPRAISAL RIGHTS
 
  Holders of Paradigm Common Stock are not entitled to appraisal rights under
the DGCL because Paradigm is not a constituent corporation to the Merger
Agreement under the DGCL.
 
RESALE OF PARADIGM COMMON STOCK
 
  The Paradigm Common Stock issued in connection with the Merger will be
freely transferable, except that shares issued to any IXYS stockholder who is
an Affiliate of IXYS or who becomes an Affiliate of the Combined Company are
subject to certain restrictions on resale. An Affiliate is defined generally
as including, without limitation, directors, certain executive officers and
certain other persons who control a company. Certain stockholders of IXYS who
may be deemed to be Affiliates have executed agreements that prohibit the
sale, transfer or other disposition of common stock of the Combined Company
received by such stockholders in the Merger, except where such sale, transfer
or other disposition (i) is effected pursuant to an effective registration
statement under the Securities Act, (ii) is made in conformity with the
requirements of Rule 145 under the Securities Act, (iii) is made in reliance
upon a written opinion of counsel that such sale, transfer or other
disposition is exempt from registration under the Securities Act, or (iv) is
made in reliance upon the written advice from an authorized representative of
the Commission to the effect that the Commission would take no action with
respect to such sale, transfer or other disposition. See "--Affiliate
Agreements."
 
MANAGEMENT AFTER THE MERGER
 
  At the Effective Time, all directors and executive officers of Paradigm
shall resign from their respective positions as director or executive officer
(but not as employee), except for Mr. Kochman who shall remain as a director
of the Combined Company. At the Effective Time, Dr. Zommer, Mr. Agbayani and
Dr. Karg will be appointed to the board of directors of the Combined Company.
It is currently expected that the executive officers of IXYS will serve after
the Effective Time as the executive officers of the Combined Company.
 
          THE PARADIGM BOARD RECOMMENDS A VOTE "FOR" THE APPROVAL OF
                            THE ISSUANCE PROPOSAL.
 
            THE IXYS BOARD RECOMMENDS A VOTE "FOR" THE APPROVAL OF
                             THE MERGER PROPOSAL.

                             THE MERGER AGREEMENT
 
GENERAL
 
  The following is a summary of the material provisions of the Merger
Agreement, a copy of which is attached as Annex 1 to this Joint Proxy
Statement/Prospectus and is incorporated herein by reference. However, the
following is not a complete statement of all provisions of the Merger
Agreement and related agreements. Statements made in this Joint Proxy
Statement/Prospectus with respect to the terms of the Merger Agreement and
such related agreements are qualified in their respective entireties by
reference to the more detailed information set forth in the Merger Agreement
and such related agreements.
 
  The Merger Agreement provides for the merger of Merger Subsidiary with and
into IXYS. As a result of the Merger, Merger Subsidiary will cease to exist,
IXYS will become a wholly-owned subsidiary of Paradigm and the former
stockholders of IXYS will become the holders of a majority of the outstanding
shares of Paradigm Common Stock. IXYS will continue as the surviving
corporation of the Merger (the "Surviving Corporation") and will retain all of
its separate corporate existence, with all its purposes, objects, rights,
privileges, powers and franchises unaffected by the Merger. Merger Subsidiary
has been formed solely for the purpose of effecting the Merger, and there will
be no other activity in Merger Subsidiary. The Merger will become effective
upon the filing of a Certificate of Merger with the Delaware Secretary of
State. Such filing is anticipated to take place as soon as practicable after
the approval of the Merger Proposal by the IXYS stockholders and approval of
the Issuance Proposal, Reverse Stock Split Proposal, Increased Authorization
Proposal and Name Change Proposal by the Paradigm stockholders, subject to the
satisfaction or waiver of the other conditions to the Merger. It is currently
anticipated that the Merger will be consummated, and the Effective Time will
occur, in August 1998. There can be no assurance, however, that the conditions
to the Merger will be satisfied by such date, or at all, or that the Merger
Agreement will not be terminated. See "--Conditions to the Merger" and "The
Merger Proposal and the Issuance Proposal--Regulatory Matters."
 
MERGER CONSIDERATION
 
  IXYS Capital Stock. Subject to the provisions contained in the Merger
Agreement relating to the payment of cash in lieu of fractional shares, at the
Effective Time, each share of IXYS Capital Stock then outstanding (except for
any such shares held by IXYS as treasury stock and any shares held by Paradigm
or any subsidiary of Paradigm or IXYS) will be converted into the right to
receive Paradigm Common Stock based on the Exchange Ratio.
 
  The Exchange Ratio shall be the greater of two ratios. The two ratios will
be evaluated, and the greater of the two ratios will be determined and fixed,
immediately prior to the Effective Time. The Percentage Formula Ratio will be
determined according to the following formula:
 
                                  A = 19 X  B
                                      -------
                                         C
 
where "A" is the Percentage Formula Ratio, "B" is the fully diluted
capitalization of Paradigm, immediately prior to the Effective Time and having
given effect to the Reverse Stock Split, expressed as the sum of (x) the
number of shares of Paradigm Common Stock outstanding, (y) the number of
shares of Paradigm Common Stock into which the outstanding Paradigm Preferred
Stock converts and (z) the aggregate number of shares of Paradigm Common Stock
for which outstanding warrants, options or other rights to acquire Paradigm
Common Stock are exercisable and "C" is the fully diluted capitalization of
IXYS immediately prior to the Effective Time, expressed as the sum of (A) the
number of shares of IXYS Common Stock outstanding, (B) the number of shares of
IXYS Common Stock issuable upon conversion of the outstanding shares of IXYS
Preferred Stock and (C) the aggregate number of shares of IXYS Common Stock
for which outstanding warrants, options or other rights to acquire IXYS Common
Stock are exercisable.
 
                                      55
<PAGE>
 
  The Valuation Formula Ratio will be determined according to the following
formula:
 
                               D = $150,000,000
                                    ---------
                                     (E X C)
 
where "D" is the Valuation Formula Ratio, "E" is the average of the closing
sale prices of Paradigm Common Stock for the ten trading days ending (and
including) the trading day two business days prior to the date of the Paradigm
Annual Meeting (appropriately adjusted to reflect the Reverse Stock Split) and
"C" is the IXYS Fully Diluted Capitalization.
 
  For illustrative purposes only, the table below sets forth examples
estimating the Exchange Ratio for several alternative values of Paradigm
Common Stock.

</TABLE>    
  --------
  (1) Stock price based on fluctuating stock prices for illustrative
      purposes.
     
  (2) Based on the proposed 15-for-1 reverse stock split. Please note that
      where the initial stock price of Paradigm Common Stock was less than
      $3.311107 per share, the Valuation Formula Ratio was used because the
      value of the total number of shares the IXYS stockholders would receive
      under the Percentage Formula Ratio (in using that price) would have
      been less than $150 million. Conversely, if the initial stock price of
      Paradigm was more than $3.311107 per share, then the Percentage Formula
      Ratio was used. Therefore, all exchange ratio calculations made based
      on initial stock prices of Paradigm that were above $3.311107 were
      calculated using the Percentage Formula Ratio and all exchange ratio
      calculations made based on initial stock prices of Paradigm that were
      below $3.311107 were calculated using the Valuation Formula Ratio.
      Therefore, the "benchmark" stock price is $3.311107 per share.     
 
  For each value of Paradigm Common Stock set forth in the foregoing table,
the table assumes that the outstanding shares of Paradigm Preferred Stock are
converted into Paradigm Common Stock in accordance with the terms of the
Paradigm Certificate of Incorporation based upon a five (5) day closing bid
price average equivalent to the value set forth for Paradigm Common Stock in
the table. The number of shares of Paradigm Common Stock issuable upon
conversion of the Paradigm Preferred Stock is subject to adjustment depending
on the date of the conversion thereof, and could be materially less or more
than such estimated amount depending
 
                                      56
<PAGE>
 
   
on factors which cannot be predicted by Paradigm, including, among other
things, the future market price of Paradigm Common Stock. Additionally, for
each value of Paradigm Common Stock set forth in the foregoing table, the
table assumes that the ten (10) day average of closing sale prices for
Paradigm Common Stock to be used in the Valuation Formula Ratio is equivalent
to the value set forth in the table. Additionally, the table assumes (i) a
variable number of shares representing the Paradigm Fully Diluted
Capitalization which, as of June 16, 1998, was 223,128 shares and (ii) an IXYS
Fully Diluted Capitalization of 208,350,429 shares, based on securities
outstanding on June 16, 1998. Finally, the table assumes the Reverse Stock
Split has taken place (collectively, the "Exchange Ratio Assumptions").
Consequently, at any given value for Paradigm Common Stock in the table, the
actual Exchange Ratio will vary from the number set forth in the table if the
averages of the closing sale prices of Paradigm Common Stock differ from one
another or the price of Paradigm Common Stock at the Effective Time or if the
fully diluted capitalization of either company at the Effective Time varies
from the amount assumed herein. The actual value of the consideration and the
number of shares to be issued by Paradigm may differ from the value of the
consideration and the number of shares to be issued in accordance with the
Assumed Exchange Ratio. The number of shares to be issued in connection with
the Valuation Formula Ratio (if such exchange ratio is used) will not be
determined until immediately preceding the Annual Stockholder Meeting of
Paradigm and the number of shares to be issued in connection with the
Percentage Formula Ratio (if such exchange ratio is used) will not be
determined until immediately prior to the Effective Time. In both instances,
fluctuating market conditions relating to Paradigm's trading price are a
factor and may cause the final exchange ratio to be different from the Assumed
Exchange Ratio.     
 
  As of June 16, 1998, the value of the IXYS Fully Diluted Capitalization
would be less than $150 million if the Percentage Formula Ratio were used.
Therefore, in accordance with the Merger Agreement, the Valuation Formula
Ratio was used to calculate the Assumed Exchange Ratio instead of the
Percentage Formula Ratio.
 
  No Fractional Shares. No fractional shares of Paradigm Common Stock will be
issued in connection with the Merger, and no certificates or scrip for any
such fractional shares will be issued. In lieu of such fractional shares, any
holder of IXYS Capital Stock who would otherwise be entitled to receive a
fraction of a share of Paradigm Capital Stock (after aggregating all
fractional shares of Paradigm Common Stock issuable to such holder) will, upon
surrender of such holder's stock certificate(s) representing IXYS Capital
Stock to the Exchange Agent, be paid in cash the dollar amount (rounded to the
nearest whole cent), without interest, determined by multiplying such fraction
by the closing price of a share of Paradigm Common Stock on the Nasdaq
SmallCap Market on the date the Merger becomes effective.
 
STOCK OPTIONS; WARRANTS
 
  Stock Options. At the Effective Time, all rights with respect to IXYS Common
Stock in connection with IXYS Options then outstanding shall be converted into
and become rights with respect to Paradigm Common Stock, and each such option
shall be assumed by Paradigm and continue to have, and be subject to, the same
terms and conditions, including any restriction on the exercise of any such
option, except that (i) each such option assumed by Paradigm may be
exercisable solely for shares of Paradigm Common Stock; (ii) the number of
shares of Paradigm Common Stock subject to each such option shall be equal to
the number of shares of IXYS Common Stock subject to such option immediately
prior to the Effective Time multiplied by the Exchange Ratio and rounded down
to the nearest whole share (with cash, less the applicable exercise price,
being payable for any fraction of a share); and (iii) the exercise price per
share under each such option shall equal the exercise price immediately prior
to the Effective Time divided by the Exchange Ratio and rounding up to the
nearest hundredth of a cent. After the Effective Time, Paradigm will file with
the Commission, no later than 30 days after the date on which the Registration
Statement on Form S-4 becomes effective, a Registration Statement on Form S-8
relating to the shares of Paradigm Common Stock issuable with respect to the
assumed IXYS Options.
 
  Warrants. At the Effective Time, all rights with respect to IXYS Warrants
then outstanding shall be converted into and become rights with respect to
Paradigm Common Stock, and Paradigm shall assume each such IXYS Warrant in
accordance with the terms of the Warrant by which it is evidenced, except that
(i) each such IXYS Warrant assumed by Paradigm may be exercised solely for
shares of Paradigm Common Stock;
 
                                      57
<PAGE>
 
(ii) the number of shares of Paradigm Common Stock subject to each such IXYS
Warrant shall be equal to the number of shares of IXYS Common Stock subject to
such IXYS Warrant immediately prior to the Effective Time multiplied by the
Exchange Ratio, rounding down to the nearest whole share (with cash, less the
applicable exercise price, being payable for any fraction of a share); and
(iii) the per share exercise price under each such IXYS Warrant shall be
adjusted by dividing the per share exercise price under such IXYS Warrant by
the Exchange Ratio and rounding up to the nearest hundredth of a cent.
 
STOCK OWNERSHIP FOLLOWING THE MERGER
   
  Assuming the Exchange Ratio Assumptions, the occurrence of the Reverse Stock
Split and a price per share of Paradigm Common Stock of $18.519 (after the
Reverse Stock Split), the Assumed Exchange Ratio based on the Valuation
Formula Ratio of 0.038876 would result. At the Assumed Exchange Ratio and
based upon the foregoing assumptions, an aggregate of approximately 7,138,459
shares of Common Stock of the Combined Company will be issued to holders of
IXYS Common Stock and an additional approximately 961,372 shares of Common
Stock of the Combined Company will be issuable to holders of options and
warrants exercisable for IXYS Capital Stock. Based upon the number of shares
of Paradigm Common Stock issued and outstanding as of the Paradigm Record
Date, and after giving effect to the Reverse Stock Split and the additional
shares of Paradigm Common Stock that are proposed to be issued in the Merger
and assuming the Valuation Formula Exchange Ratio is applicable (and assuming
no exercise of outstanding options to purchase Paradigm Common Stock or IXYS
Common Stock), the former holders of IXYS Capital Stock would hold
approximately 97.1% of the Combined Company's total issued and outstanding
shares and the former stockholders of Paradigm will hold the balance of the
Combined Company's total issued and outstanding shares, estimated to be
approximately 2.9%.     
 
CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES
 
  As soon as reasonably practicable after the Effective Time, the Exchange
Agent will mail to the registered holders of IXYS Common Stock (i) the Letter
of Transmittal and (ii) instructions for use of the Letter of Transmittal in
effecting the surrender of IXYS Stock Certificates in exchange for
certificates representing Paradigm Common Stock. Upon surrender of an IXYS
Stock Certificate to the Exchange Agent for exchange, together with a duly
executed Letter of Transmittal and such other documents as may be reasonably
required by the Exchange Agent or Paradigm, the holder of such IXYS Stock
Certificate shall be entitled to receive in exchange therefor a certificate
representing the whole number of shares of Paradigm Common Stock that such
holder has the right to receive. No fractional shares of Paradigm Common Stock
will be issued in connection with the Merger, and no certificates for any such
fractional shares will be issued. After the Effective Time and until
surrendered as provided above, such certificates shall be deemed to represent
only the right to receive certificates representing the number of shares of
Paradigm Common Stock into which the shares of IXYS Capital Stock formerly
represented by such IXYS stock certificates were converted in the Merger and a
cash payment in lieu of any fractional shares. See "--No Fractional Shares."
Although holders of IXYS Capital Stock are encouraged to surrender their stock
certificates for exchange promptly after the consummation of the Merger, there
is no deadline for holders of IXYS Capital Stock to surrender their stock
certificates in exchange for certificates representing the common stock of the
Combined Company.
 
  IXYS STOCKHOLDERS ARE REQUESTED NOT TO SURRENDER THEIR IXYS STOCK
CERTIFICATES FOR EXCHANGE UNTIL SUCH TRANSMITTAL LETTER AND INSTRUCTIONS ARE
RECEIVED BY THEM.
 
EFFECT ON CERTIFICATES
 
  At the Effective Time, (i) all shares of IXYS Common Stock outstanding
immediately prior to the Effective Time will automatically be canceled and
retired and will cease to exist, and all holders of certificates representing
shares of IXYS Common Stock that were outstanding immediately prior to the
Effective Time will cease to have any rights as stockholders of IXYS, and (ii)
the stock transfer books of IXYS will be closed with respect to all
 
                                      58
<PAGE>
 
shares of IXYS Common Stock outstanding immediately prior to the Effective
Time. No further transfer of any such shares of IXYS Capital Stock will be
made on such stock transfer books after the Effective Time. If, after the
Effective Time, an IXYS Stock Certificate is presented to the Exchange Agent
(or to IXYS or Paradigm), such IXYS Stock Certificate will be canceled and
will be exchanged as provided above under the caption "--Conversion of Shares;
Procedures for Exchange of Certificates."
 
CORPORATE MATTERS
 
  As of the Effective Time, the Certificate of Incorporation of the Surviving
Corporation will be amended and restated to conform to the form of certificate
of incorporation attached to the Merger Agreement, and the Bylaws of the
Surviving Corporation will be the Bylaws of IXYS as in effect immediately
prior to the Effective Time. The Merger Agreement provides that concurrently
with the Effective Time, certain directors and officers of Paradigm will
resign and the directors of the Combined Company immediately after the
Effective Time shall be Messrs. Zommer, Karg, Agbayani and Kochman, and the
officers of the Combined Company immediately after the Effective Time shall be
the officers of IXYS, occupying corresponding positions at the Combined
Company.

  In addition, Paradigm shall maintain in effect for a period of three years
after the Effective Time the policy of officers' and directors' liability
insurance maintained by Paradigm on the date of the Merger Agreement, with
coverage in the amount and scope, subject to certain limitations, at least as
favorable as the Paradigm's existing directors' and officers' liability
insurance coverage. Such limitations include the fact that the Combined
Company shall not be required to maintain the directors' and officers'
liability insurance as of the date of the Merger Agreement if equivalent
coverage is provided to such directors and officers under another policy of
directors' and officers' liability insurance. Further, if  coverage is
provided to such persons under another policy of officers' and directors'
liability insurance, the Combined Company shall not be required to expend in
any one year an amount in excess of 150% of the annual premium currently paid
by Paradigm for such insurance, and if the annual premiums of such insurance
coverage exceed 150% of the annual premium currently paid by Paradigm for such
insurance, the Combined Company shall be obligated to obtain a policy with the
greatest coverage available for a cost not exceeding such amount. See "The
Merger Agreement--Indemnification and Insurance."

    (x) there shall not be any pending or threatened legal proceeding in
  which there is a reasonable possibility of an outcome that would have a
  materially adverse effect on IXYS or Paradigm;
 
    (xi) all Paradigm tax returns due to be filed on or before the Closing
  Date shall have been filed and shall have been prepared in all material
  respects in compliance with all applicable legal requirements; and
 
    (iv) all material consents required to be obtained by Paradigm in
  connection with the Merger shall have been obtained by Paradigm and shall
  be in full force and effect.
 
  Although IXYS does not currently expect to waive any of the conditions as
set forth in the Merger Agreement, IXYS would consider waiving the following
conditions (as described above) in order to consummate the Merger: (i), (ii),
(iv) with respect to the Affiliate Agreements, the legal opinion of Pillsbury,
and the certificate executed by the Chief Executive Officer, (vii), (x), and
(xi). The parties do not currently expect to amend the registration statement
and resolicit proxies if such conditions are waived unless the event giving
rise to such waiver would materially and adversely affect the stockholders of
Paradigm or IXYS or give rise to a materially altered transaction.

TERMINATION
 
  The Merger Agreement may be terminated prior to the Effective Time:
 
    (i) by mutual written consent of Paradigm and IXYS;
 
    (ii) by either Paradigm or IXYS if the Merger shall not have been
  consummated by August 14, 1998 (unless the failure to consummate the Merger
  is attributable to a failure on the part of the party seeking to terminate
  the Merger Agreement to perform any material obligation required to be
  performed by such party at or prior to the Effective Time);
 
    (iii) by either Paradigm or IXYS if a court of competent jurisdiction or

  been adopted at such Paradigm Annual Meeting (or in the case of the sixty-
  for-one reverse stock split, in conjunction with any prior Paradigm
  stockholder meeting following the date of the Merger Agreement) by the
  Paradigm stockholders;     
 
    (vi) by IXYS (at any time prior to the adoption of the Merger Agreement
  by the Paradigm Required Vote) if a Triggering Event shall have occurred;
 
    (vii) by Paradigm if any of IXYS' representations and warranties
  contained in the Merger Agreement shall be or shall have become materially
  inaccurate, or if any of IXYS' covenants contained in the Merger Agreement
  shall have been breached in any material respect; provided, however, that
  if an inaccuracy in IXYS' representations and warranties or a breach of a
  covenant by IXYS is curable by IXYS and IXYS is continuing to exercise all
  reasonable efforts to cure such inaccuracy or breach, then Paradigm may not
  terminate the Merger Agreement on account of such inaccuracy or breach; or
 
    (viii) by IXYS if any of Paradigm's representations and warranties
  contained in the Merger Agreement shall be or shall have become materially
  inaccurate, or if any of Paradigm's covenants contained in the Merger
  Agreement shall have been breached in any material respect; provided,
  however, that if an inaccuracy in Paradigm's representations and warranties
  or a breach of a covenant by Paradigm is curable by Paradigm and Paradigm
  is continuing to exercise all reasonable efforts to cure such inaccuracy or
  breach, then IXYS may not terminate the Merger Agreement on account of such
  inaccuracy or breach.
 
EXPENSES AND TERMINATION FEES
 
  All fees and expenses incurred in connection with the Merger Agreement and
the transactions contemplated by the Merger Agreement shall be paid by the
party incurring such expenses, whether or not the Merger is consummated;
provided, however, (i) if the Merger Agreement is terminated by Paradigm or
IXYS because the Issuance Proposal, the Reverse Stock Split Proposal, the
Increase Authorization Proposal or the Name Change Proposal has not been
adopted at the Paradigm Annual Meeting or the Paradigm Preferred Stock
Conversion has not been effectuated, or if the Merger Agreement is terminated
by IXYS because a Triggering Event has occurred, and (ii) if prior to the date
six months after the date of such termination, (A) Paradigm enters into any
agreement involving an Acquisition Transaction, (B) a tender offer, an
exchange offer, or a share exchange is commenced that would constitute an
Acquisition Transaction if completed or (C) an Acquisition Transaction is
otherwise consummated (each, the "Alternate Transaction") then, upon
consummation of such Alternate Transaction, Paradigm shall pay to IXYS, in
cash, a nonrefundable fee in the amount of $500,000. If the Merger Agreement
is terminated by Paradigm or IXYS because the Merger Agreement shall not have
been adopted at the IXYS Special Meeting, then IXYS shall pay to Paradigm a
nonrefundable fee in the amount of $500,000 to cover Paradigm's expenses in
connection with the proposed transaction.

  In a separate agreement, ABB agreed that if IXYS were required to pay the
termination fee described above, ABB would reimburse IXYS in an amount not to
exceed $500,000 if (i) IXYS did not, on or prior to the date on which ABB was
required to vote its shares on the Merger Agreement, waive any rights IXYS may
have not to consummate the Merger because of Paradigm's failure to meet the
condition relating to the absence of any material adverse change with respect
to Paradigm and (ii) Dr. Zommer had voted all of the shares of IXYS Capital
Stock owned by him in favor of the Merger Proposal.
 
AMENDMENT OF THE MERGER AGREEMENT
 
  The Merger Agreement may be amended in writing with the approval of the

of the Merger; provided, however, that after such approval, no amendment shall
be made which requires further approval of IXYS' stockholders or Paradigm's
stockholders without such stockholder approval.

                       THE REVERSE STOCK SPLIT PROPOSAL
                     
                  APPROVAL OF A FIFTEEN-FOR-ONE REVERSE     
                    STOCK SPLIT OF PARADIGM'S COMMON STOCK
 
INTRODUCTION
   
  In June 1998, the Paradigm Board approved, subject to stockholders' approval
solicited hereby, a proposal to amend Paradigm's Certificate of Incorporation
to effectuate a reverse stock split of Paradigm's Common Stock in a ratio of
fifteen-for-one (such that every fifteen shares shall be combined into one
share).     
   
  The directors propose to amend Paradigm's Certificate of Incorporation to
reclassify the Paradigm Common Stock to effectuate a fifteen-for-one reverse
stock split, par value $.01 per share, such that for every fifteen (15) pre-
amendment common shares held by a stockholder, such holder would be entitled
to one (1) post-amendment common share, fractional shares being rounded up to
the nearest full post-amendment share, and outstanding warrants and options to
purchase stock being adjusted accordingly. The Reverse Stock Split will become
effective upon the filing with the Secretary of State of Delaware of an
amendment to Paradigm's Certificate of Incorporation.     
   
  Adjustments to the corporate financial statements to reflect the
reclassification and reverse split are expected to be minimal. The immediate
effect in the market would be expected to increase the trading price per share
fifteenfold, and to decrease the number of post-amendment shares involved in a
trade to one-fifteenth of the pre-amendment number of shares that would have
been involved in an identical trade. Outstanding pre-amendment shares of
Paradigm Common Stock of approximately 1,779,401 would become approximately
118,627 outstanding post-amendment shares.     
 
PURPOSE OF REVERSE STOCK SPLIT
   
  One of the conditions to IXYS' obligation to consummate the Merger as set
forth in the Merger Agreement is that Paradigm effect a one hundred-fifty-for-
one reverse stock split in one or more steps. Paradigm's stockholders
approved, at a Paradigm Special Meeting of Stockholders, a ten-for-one reverse
stock split. The Paradigm Special Meeting was held on May 1, 1998. In
conjunction with the ten-for-one reverse stock split, the proposed fifteen-
for-one reverse stock split as set forth in this Reverse Stock Split Proposal,
if approved, fulfills Paradigm's obligations under the Merger Agreement.     
 
  Holders of Paradigm Common Stock have no preemptive or other subscription
rights.
 
PRINCIPAL EFFECTS OF THE REVERSE STOCK SPLIT
 
  If the stockholders approve the Reverse Stock Split Proposal, Paradigm's
Certificate of Incorporation will be amended to replace the existing provision
relating to Paradigm's authorized capital with the following provision.
Accordingly, the last sentence of the second paragraph of Article IV(B) of the
Certificate of Incorporation shall be amended to read as follows:
     
    "Each fifteen (15) shares of the Common Stock of the Corporation issued
  as of the date and time immediately preceding [insert Date which Amended
  Certificate is filed], the effective date of a reverse stock split (the
  "Split Effective Date") shall be automatically changed and reclassified, as
  of the Split Effective Date and, without further action, into one (1) fully
  paid and nonassessable share of Common Stock of the Corporation; provided,
  however, that any fractional interest resulting from such change and
  classification shall be rounded upward to the nearest whole share."     
 
  If the stockholders approve the Reverse Stock Split Proposal, the above
amendment to Paradigm's Certificate of Incorporation shall become effective
upon the filing of an amendment to the Certificate of Incorporation with the
Delaware Secretary of State.
 
                                      67
<PAGE>
 
   
  The proposed Reverse Stock Split (without giving effect to the Merger) will
not affect any stockholder's proportionate equity interest in Paradigm or the
rights, preferences, privileges or priorities of any stockholder, other than
an adjustment which may occur due to the rounding up of fractional shares. The
proposed Reverse Stock Split, however, may result in a stockholder incurring
greater trading costs due to some stockholders becoming holders of less than
one hundred (100) shares of Paradigm Common Stock. Likewise, the proposed
Reverse Stock Split (without giving effect to the Merger) will not affect the
total stockholders' equity of Paradigm or any components of stockholders'
equity as reflected on the financial statements of Paradigm except (i) to
change the numbers of the issued and outstanding shares of capital stock and
(ii) for an adjustment which will occur due to the costs incurred by Paradigm
in connection with this Joint Proxy Statement/Prospectus and the
implementation of such of the proposals as are approved by the stockholders.
However, because the number of shares of capital stock that Paradigm is
authorized to issue will not be decreased in proportion to the fifteen-for-one
reverse stock split, the number of shares which are authorized but unissued,
and the percentage of ownership of Paradigm represented by such shares if they
are issued in the future in the discretion of the Paradigm Board, effectively
will be increased.     
 
EFFECT OF THE REVERSE STOCK SPLIT
 
  The following table illustrates the principal effects on Paradigm's capital
stock of the Reverse Stock Split:

(2) Excludes approximately (i) 133,834 shares issuable upon exercise of
    outstanding options (approximately 8,922 shares after the Reverse Stock
    Split), (ii) 39,500 shares issuable upon exercise of outstanding warrants
    (approximately 2,634 shares after the Reverse Stock Split), each as of
    June 16, 1998 and (iii) 112 shares of Paradigm Preferred Stock which are
    convertible into approximately 1,394,172 shares of Paradigm Common Stock
    (approximately 92,945 shares after the Reverse Stock Split).     
 
EXCHANGE OF SHARES; NO FRACTIONAL SHARES
   
  Pursuant to the proposed Reverse Stock Split, every fifteen (15) shares of
issued Paradigm Common Stock would be converted and reclassified into one (1)
share of post-split Paradigm Common Stock, and any fractional interests
resulting from such reclassification would be rounded upward to the nearest
whole share. For example, a holder of one hundred (100) shares prior to the
Split Effective Date would be the holder of seven (7) shares at the Split
Effective Date, and the holder of thirty (30) shares prior to the Split
Effective Date would be the holder of two (2) shares at the Split Effective
Date. All shares held by a stockholder will be aggregated and one new stock
certificate will be issued, unless the transfer agent is otherwise notified by
the stockholder. The proposed Reverse Stock Split would become effective
immediately following the Split Effective Date. Stockholders will be notified
on or after the Split Effective Date that the Reverse Stock Split has been
effected. Paradigm's transfer agent, ChaseMellon Shareholder Services, L.L.C.
will act as Paradigm's exchange agent (the "Exchange Agent") for stockholders
in implementing the exchange of their certificates.     
 
  As soon as practicable after the Split Effective Date, stockholders will be
notified and provided the opportunity (but shall not be obligated) to
surrender their certificates to the Exchange Agent in exchange for
 
                                      68
<PAGE>
 
certificates representing post-split Paradigm Common Stock. Stockholders will
not receive certificates for shares of post-split Paradigm Common Stock unless
and until the certificates representing their shares of pre-split Paradigm
Common Stock are surrendered and they provide such evidence of ownership of
such shares as Paradigm or the Exchange Agent may require. Stockholders should
not forward their certificates to the Exchange Agent until they have received
notice from Paradigm that the Reverse Stock Split has become effective.
Beginning on the Split Effective Date, each certificate representing shares of
Paradigm's pre-split Common Stock will be deemed for all corporate purposes to
evidence ownership of the appropriate number of shares of post-split Paradigm
Common Stock.
 
  No service charge will be payable by stockholders in connection with the
exchange of certificates, all costs of which will be borne and paid by
Paradigm.
 
CHANGE OF CONVERSION RATIO FOR CONVERTIBLE PREFERRED STOCK AND NOTICE TO
HOLDERS OF SUCH STOCK
   
  Pursuant to the authority conferred on it by the Paradigm Certificate of
Incorporation, the Paradigm Board adopted certain resolutions dated January 9,
1997, July 11, 1997 and November 14, 1997, respectively (the "Board
Resolutions"), pursuant to which Paradigm issued Paradigm Series A Preferred
Stock, Paradigm Series B Preferred Stock, and Paradigm Series C Preferred
Stock. The Paradigm Series A Preferred Stock, Paradigm Series B Preferred
Stock and Paradigm Series C Preferred Stock are all convertible into shares of
Paradigm Common Stock as is determined by dividing (A) the sum of (1) $10,000
plus (2) the amount of all accrued but unpaid or accumulated dividends on the
shares of Paradigm Preferred Stock being converted by (B) the conversion price
in effect at the time of conversion for each of the Paradigm Series A
Preferred Stock, the Paradigm Series B Preferred Stock and the Paradigm Series
C Preferred Stock. The conversion price is equal to the lower of (i) $337.50,
$206.25 and $88.50 for the Paradigm Series A Preferred Stock, Paradigm Series
B Preferred Stock and Paradigm Series C Preferred Stock, respectively (after
the Reverse Stock Split) or (ii) eighty-two percent (82%) of the average
closing bid price of a share of Paradigm Common Stock as quoted on the Nasdaq
SmallCap Market (or such other national or regional securities exchange or
automated quotations system upon which the Paradigm Common Stock is listed and
primarily traded) over the five (5) consecutive trading days immediately
preceding the date of the conversion.     
 
  In accordance with the terms of those Board Resolutions, the conversion
ratios for Paradigm Series A Preferred Stock, Paradigm Series B Preferred
Stock and Paradigm Series C Preferred Stock will be adjusted concurrently with
the Split Effective Date so that the record owner of Paradigm Series A
Preferred Stock, Paradigm Series B Preferred Stock and Paradigm Series C
Preferred Stock shall be entitled to receive upon exercise of such conversion
the number of shares of Paradigm Common Stock that he would have owned or been
entitled to receive after the Reverse Stock Split had such holder exercised
his or her option to convert immediately prior to the Split Effective Date.
Paradigm will send to each record owner of Paradigm Series A Preferred Stock,
Paradigm Series B Preferred Stock and Paradigm Series C Preferred Stock,
notice of such adjustments.
 
MATERIAL FEDERAL INCOME TAX CONSEQUENCES
 
  The following discussion summarizes the material federal income tax
considerations of the Reverse Stock Split that are generally applicable to
holders of Paradigm Common Stock. This discussion is based on currently
existing provisions of the Code, existing Treasury Regulations thereunder and
current administrative rulings and court decisions, all of which are subject
to change. Any such change, which may or may not be retroactive, could alter
the tax consequences to the Paradigm stockholders.
 
  Paradigm stockholders should be aware that this discussion does not deal
with all federal income tax considerations that may be relevant to particular
Paradigm stockholders in light of their particular circumstances, such as
stockholders who are dealers in securities, banks, insurance companies or tax-
exempt organizations, who are subject to the alternative minimum tax
provisions of the Code, who are non-United States persons, who
 
                                      69
<PAGE>
 
acquired their shares in connection with stock option or stock purchase plans
or in other compensatory transactions or who hold their shares as a hedge or
as part of a hedging, straddle, conversion or other risk reduction
transaction. In addition, the following discussion does not address the tax
consequences of the Reverse Stock Split under foreign, state or local tax laws
or the tax consequences of transactions effectuated prior to or after the
Reverse Stock Split (whether or not such transactions are in connection with
the Reverse Stock Split).
 
  It is the opinion of Pillsbury that if the Reverse Stock Split is carried
out in accordance with its description herein, the Reverse Stock Split will
constitute a Reorganization pursuant to section 368(a) of the Code and that,
accordingly, for U.S. federal income tax purposes:
 
  .  Neither Paradigm nor the holders of Paradigm Common Stock will recognize
     any gain or loss upon the exchange of Paradigm Common Stock for a
     reduced number of shares of Paradigm Common Stock.
 
  .  Holders of Paradigm Preferred Stock will recognize no income, gain or
     loss as a result of the changes to the conversion ratios for such stock
     incident to the Reverse Stock Split.
 
  .  The aggregate tax basis for computing gain or loss of Paradigm Common
     Stock to be issued as a result of the Reverse Stock Split will be the
     same as the stockholder's aggregate tax basis in the Paradigm Common
     Stock surrendered in exchange therefor.
 
  .  The holding period of Paradigm Common Stock to be issued as a result of
     the Reverse Stock Split will include the holding period for the shares
     of Paradigm Common Stock surrendered in exchange therefor, provided that
     such shares of stock were held by the stockholder as capital assets on
     the Split Effective Date.
 
  THE PRECEDING DISCUSSION DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR
DISCUSSION OF ALL POTENTIAL TAX EFFECTS RELEVANT TO THE REVERSE STOCK SPLIT.
THUS, HOLDERS OF PARADIGM COMMON STOCK ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM OF THE REVERSE STOCK
SPLIT, INCLUDING TAX RETURN REPORTING REQUIREMENTS, THE APPLICABILITY AND
EFFECT OF FEDERAL, STATE, LOCAL AND OTHER APPLICABLE TAX LAWS AND THE EFFECTS
OF ANY PROPOSED CHANGES IN THE TAX LAWS.
 
VOTE NECESSARY TO APPROVE THE PROPOSAL
 
  Each holder of Paradigm Common Stock is entitled to one vote per share held.
The holders of a majority of the shares of the Paradigm Common Stock issued
and outstanding shall constitute a quorum. The affirmative vote of holders of
a majority of the outstanding shares of Paradigm Common Stock is required for
approval of the Reverse Stock Split Proposal. In the event that a quorum is
not present or represented by proxy at the Paradigm Annual Meeting, the
stockholders entitled to vote at the meeting present in person or by proxy
shall have power to adjourn the Paradigm Annual Meeting until a quorum shall
be present or represented. Proxies solicited by the Paradigm Board will be
voted for approval of the Reverse Stock Split Proposal, unless otherwise
instructed.
 
  A stockholder voting through a proxy who abstains with respect to approval
of the Reverse Stock Split Proposal shall be considered to have cast a
negative vote with respect to the Reverse Stock Split Proposal, but shall be
treated as present and entitled to vote on the approval of the other proposals
presented to the stockholders of the Paradigm Annual Meeting; provided,
however, that a stockholder (including a broker) who does not give authority
to a proxy to vote on the approval of the other Proposals shall not be
considered present and entitled to vote on the other Proposals.
 
  In the event that the Reverse Stock Split Proposal is approved by the
Paradigm stockholders and the Merger Proposal and the Issuance Proposal is not
approved by the Paradigm stockholders, Paradigm will take no action to
implement the Reverse Stock Split Proposal.

                     THE INCREASED AUTHORIZATION PROPOSAL
           APPROVAL TO AMEND PARADIGM'S CERTIFICATE OF INCORPORATION
          TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF COMMON STOCK
 
INTRODUCTION
 
  Paradigm's Certificate of Incorporation currently authorizes the issuance of
twenty-five million (25,000,000) shares of Paradigm Common Stock and five
million (5,000,000) shares of Paradigm Preferred Stock, each par value $.01
per share. The Paradigm Board in March 1998, adopted a resolution proposing
that the Paradigm Certificate of Incorporation be amended to increase the
authorized number of shares of Paradigm Common Stock to forty million
(40,000,000), par value $.01 per share, subject to stockholder approval of the
amendment.
 
  As of June 16, 1998, Paradigm had approximately 1,779,401 shares of Paradigm
Common Stock outstanding and approximately 149,800 shares reserved for
issuance under Paradigm's employee stock plans, of which, currently,
approximately 133,834 are covered by outstanding options and approximately
4,250 are available for grant or purchase. Paradigm has also reserved 39,500
shares of Paradigm Common Stock issuable upon exercise of outstanding warrants
and approximately 1,394,172 shares of Paradigm Common Stock based upon what
Paradigm projected as of June 16, 1998 to be the approximate number of
Paradigm Common Stock shares to be issued upon conversion of Paradigm
Preferred Stock. Based upon the foregoing number of outstanding and reserved
shares of Paradigm Common Stock, Paradigm currently has approximately
21,637,127 shares remaining available for other purposes.
 
PROPOSED AMENDMENT TO THE PARADIGM CERTIFICATE OF INCORPORATION
 
  The Paradigm Board has adopted resolutions setting forth (i) the proposed
amendment to the first and second paragraphs of Article IV of Paradigm's
Certificate of Incorporation (the "Amendment"); (ii) the advisability of the
Amendment; and (iii) a call for submission of the Amendment for approval by
Paradigm's stockholders at the Paradigm Annual Meeting.
 
  The following is the text of the first and second paragraphs of Article IV
of the Paradigm Certificate of Incorporation, as proposed to be amended:
 
    "(A) This Corporation is authorized to issue 45,000,000 shares of its
  Capital Stock, which shall be divided into two classes known as "Common
  Stock' and "Preferred Stock,' respectively.
 
    (B) The total number of shares of Common Stock which this Corporation is
  authorized to issue is 40,000,000. The total number of shares of Preferred
  Stock which this Corporation is authorized to issue is 5,000,000. All of
  the shares of Common Stock and Preferred Stock shall have a par value of
  $.01 per share."
 
PURPOSE AND EFFECT OF THE PROPOSED AMENDMENT
 
  One of the conditions to IXYS' obligation to consummate the Merger as set
forth in the Merger Agreement is that Paradigm increase the authorized number
of shares of Paradigm Common Stock. The Paradigm Board believes that the
availability of additional authorized but unissued shares will provide
Paradigm with the ability to fulfill its obligations under existing agreements
by enabling it to fully convert all of the outstanding shares of Paradigm
Preferred Stock. It will also provide Paradigm with the flexibility to issue
Paradigm Common Stock for other proper corporate purposes which may be
identified in the future, such as to raise equity capital and to adopt
additional employee benefit plans or reserve additional shares for issuance
under such plans. Paradigm does not currently have plans to issue any shares
of Common Stock, other than the shares issued pursuant to the Merger.
 
  No additional action or authorization by Paradigm's stockholders would be
necessary prior to the issuance of such additional shares, unless required by
applicable law or the rules of any stock exchange or national securities
association trading system on which the Paradigm Common Stock is then listed
or quoted. Paradigm reserves the right to seek a further increase in
authorized shares from time to time in the future as considered appropriate by
the Paradigm Board.
 
  Under Paradigm's Certificate of Incorporation, Paradigm's stockholders do
not have preemptive rights with respect to Paradigm Common Stock. Thus, should
the Paradigm Board elect to issue additional shares of Paradigm Common Stock,
existing stockholders would not have any preferential rights to purchase such
shares. In addition, if the Paradigm Board elects to issue additional shares
of Paradigm Common Stock, such issuance could have a dilutive effect on the
earnings per share, voting power, and share holdings of current stockholders.
 
                                      72
<PAGE>
 
  The proposed Amendment to increase the authorized number of shares of
Paradigm Common Stock could, under certain circumstances, have an anti-
takeover effect, although this is not the intention of this proposal. For
example, in the event of a hostile attempt to take over control of Paradigm,
it may be possible for Paradigm to endeavor to impede the attempt by issuing
shares of the Paradigm Common Stock, thereby diluting the voting power of the
other outstanding shares and increasing the potential cost to acquire control
of Paradigm. The Amendment therefore may have the effect of discouraging
unsolicited takeover attempts. By potentially discouraging initiation of any
such unsolicited takeover attempt, the proposed Amendment may limit the
opportunity for Paradigm's stockholders to dispose of their shares at the
higher price generally available in takeover attempts or that may be available
under a merger proposal. The proposed Amendment may have the effect of
permitting Paradigm's current management, including the current Paradigm
Board, to retain its position, and place it in a better position to resist
changes that stockholders may wish to make if they are dissatisfied with the
conduct of Paradigm's business. However, the Paradigm Board is not aware of
any attempt to take control of Paradigm other than as described in this Joint
Proxy Statement/Prospectus, and the Paradigm Board has not presented this
proposal with the intent that it be utilized as a type of anti-takeover
device.
 
  If the proposed Amendment to increase the authorized number of shares of
Paradigm Common Stock is approved and the Reverse Stock Split as set forth in
the Reverse Stock Split Proposal is approved, the Paradigm Board will both
effectuate the Reverse Stock Split and increase the authorized number of
Paradigm Common Stock (the number of Paradigm Common Stock authorized will
increase to 40,000,000). If, on the other hand, the Reverse Stock Split is
approved but the proposed Amendment to increase to the authorized number of
shares of Paradigm Common Stock is not approved, it will have the effect of
authorizing the Paradigm Board to amend the Paradigm Certificate of
Incorporation to effectuate the Reverse Stock Split only (the authorized
number of shares of Paradigm Common Stock will remain 25,000,000). However, if
the Reverse Stock Split Proposal is not approved and the proposed Amendment to
increase the authorized number of shares of Paradigm Common Stock is approved,
it will have the effect of authorizing the Paradigm Board to amend the
Paradigm Certificate of Incorporation to only increase the authorized number

                           THE NAME CHANGE PROPOSAL
 
          APPROVAL TO AMEND THE PARADIGM CERTIFICATE OF INCORPORATION
                        TO CHANGE THE NAME OF PARADIGM
 
INTRODUCTION
 
  The Paradigm Board has determined that it is advisable to change Paradigm's
name to "IXYS Corporation", and in March 1998, voted to recommend that the
stockholders adopt an amendment to Paradigm's Certificate of Incorporation
effecting the proposed name change.
 
PURPOSE OF THE PROPOSED NAME CHANGE
 
  One of the conditions of the Merger Agreement is that Paradigm change its
name to "IXYS Corporation", which Paradigm believes will minimize confusion
when identifying the post-Merger business entity.
 
PRINCIPAL EFFECTS OF THE PROPOSED NAME CHANGE
 
  Paradigm Common Stock is currently traded on the Nasdaq SmallCap Market
under the symbol PRDM. If the proposed name change is approved by the
stockholders, the Common Stock of the Combined Company will trade under the
new symbol IXYS. There will be no interruption in trading due to the name
change or the symbol change.
 
VOTE NECESSARY TO APPROVE THE PROPOSAL
 
  Each holder of Paradigm Common Stock is entitled to one vote per share held.
The holders of a majority of the shares of Paradigm Common Stock issued and
outstanding shall constitute a quorum. The affirmative vote of holders of a
majority of the outstanding shares of Paradigm Common Stock is required for
approval of the Name Change Proposal. In the event that a quorum is not
present or represented at the Annual Meeting, the stockholders entitled to
vote at the meeting represented in person or by proxy shall have power to
adjourn the Paradigm Annual Meeting until a quorum shall be present or
represented. Proxies solicited by the Paradigm Board will be voted for
approval of the Name Change Proposal, unless otherwise instructed.
 
  A stockholder voting through a proxy who abstains with respect to approval
of the Name Change Proposal shall be considered to have cast a negative vote
with respect to the Name Change Proposal, but shall be treated as present and
entitled to vote on the approval of the other Proposals presented to the
stockholders at the Paradigm Annual Meeting; provided, however, that a
stockholder (including a broker) who does not give authority to a proxy to
vote on the approval of the other Proposals shall not be considered present
and entitled to vote on the other Proposals.
 
  In the event that the Name Change Proposal is approved by the Paradigm
stockholders and the Merger Proposal and the Issuance Proposal is not approved
by the Paradigm stockholders, Paradigm will take no action to implement the
Name Change Proposal.
 
RECOMMENDATION OF THE PARADIGM BOARD
 
  The Paradigm Board recommends a vote "FOR" the proposal to amend Paradigm's
Certificate of Incorporation to change its name to IXYS Corporation. Unless a
contrary choice is specified, proxies solicited by the Paradigm Board will be
voted FOR approval of the amendment to the Paradigm Certificate of
Incorporation to change Paradigm's name to IXYS Corporation.
 
  THE PARADIGM BOARD RECOMMENDS A VOTE "FOR" THE APPROVAL OF THE NAME CHANGE
                                   PROPOSAL.

the grant of options to Outside Directors pursuant to a nondiscretionary,
automatic grant mechanism, whereby each Outside Director is granted an option
at fair market value to purchase 313 shares of Common Stock on the date of
each Annual Meeting of Stockholders, provided such director is re-elected.
These options vest over four years at the rate of 25% per year so long as the
optionee remains an Outside Director of Paradigm. Each new Outside Director
who joins the Paradigm Board is automatically granted an option at fair market
value to purchase 1,250 shares of Common Stock upon the date on which such
person first becomes an Outside Director. These options vest over four years
at the rate of 25% per year.

(3) Amounts represent hypothetical gains that could be achieved for the

    are based on assumed rates of stock appreciation of 5% and 10% compounded
    annually from the date the respective options were granted to their
    expiration date and are not presented to forecast possible future
    appreciation, if any, in the price of the Paradigm Common Stock. The gains
    shown are net of the option exercise price, but do not include deductions
    for taxes or other expenses associated with the exercise of the options or
    the sale of the underlying shares. The actual gains, if any, on the stock
    option exercises will depend on the future performance of the Paradigm
    Common Stock, the optionee's continued employment through applicable
    resting periods and the date on which the options are exercised.

  Mr. Gulett resigned on June 15, 1998 pursuant to a resignation agreement
with Paradigm (the "Resignation Agreement"). The Resignation Agreement
provided that Mr. Gulett's existing employment contract was terminated, and in
lieu of any payments under the employment contract he would receive (i) nine
months of salary continuation, (ii) continuation of group health and welfare
benefit coverages for up to 18 months following termination (with early
termination of benefit coverages upon Mr. Gulett's obtaining comparable
benefit coverages), (iii) full vesting of Mr. Gulett's outstanding options,
and the extension of the terms of the outstanding options until June 15, 2001,
(iv) repricing of Mr. Gulett's outstanding options to an exercise price of
$0.01 per share at the Effective Date and (v) the grant of a new option to
purchase 32,000 shares of Paradigm Common Stock at an exercise price of $0.01
per share which, at the Effective Time, will be fully vested and will have a
three year term.
 
  Mr. Boswell and Paradigm entered into a letter agreement (the "Boswell
Agreement") as of June 19, 1998. Pursuant to the Boswell Agreement, Mr.
Boswell ceased accruing salary and vacation as of June 19, 1998, but will
remain an employee through the Effective Time. Following the Effective Time,
Mr. Boswell will be paid his accrued vacation and severance totaling two
months' base salary over approximately five months. The Boswell Agreement
provides that Mr. Boswell's stock options will be eligible for any repricing
or other adjustments applicable to active employees through the Effective Time
and will be fully vested at the Effective Time.
 
OPTION REPRICING
 
  In February 1997, the Paradigm Board agreed that additional incentives were
needed since many of Paradigm's employees and directors held stock options
with grants priced significantly higher than the fair market value of Paradigm
Common Stock. Therefore, Paradigm implemented a program whereby option holders
could exchange higher priced option shares for the same number of lower priced
option shares. The new options were issued on February 3, 1997 at the then
fair market value of $20.625 per share. Executive officers must remain active
on Paradigm's payroll until August 3, 1997 to exercise their new options. All
executive officers and directors holding options were eligible to participate
in this program. The total options owned by directors and executive officers
prior to the repricing represented 5% and 35%, respectively. Data for
executive officers and directors who were eligible to reprice options are
shown in the first table entitled "Ten-Year Option Repricings."
 
  In March 1998, the Paradigm Board agreed that in order to provide incentives
to its employees and directors, repricing of outstanding options was needed to
align the option exercise price more closely with the fair market value of the
underlying Paradigm Common Stock as determined by the market place. Therefore,
Paradigm implemented a program whereby option holders could exchange higher
priced option shares for the same number of lower priced option shares. The
new shares were issued on March 6, 1998 at $3.187 per share, which is 85% of
the fair market value of $3.75. Executive officers must remain active on
Paradigm's payroll to exercise their new options. All executive officers and
directors holding options were eligible to participate in this program. The
total options owned by directors and executive officers prior to the repricing
represented 3% and 64%, respectively. Data for executive officers and
directors who were eligible to reprice shares are shown in the second table
entitled "Ten-Year Option Repricings."

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Commission requires disclosure where an executive officer of a company
served or serves as a director or on the compensation committee of another
entity and an executive officer of such other entity served or serves as a
director or on the compensation committee of the company. Michael Gulett,
Paradigm's former President, Chief Executive Officer and director,
participated in Paradigm Board meetings where compensation and stock option
matters were discussed. Decisions as to executive compensation are made by the
Compensation Committee and the Stock Option Committee. During fiscal year
1997, the Compensation Committee and the Stock Option Committee were comprised
entirely of non-employee directors. Such committees did not meet during fiscal
year 1997.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
  NKK. During the years ended December 31, 1995, 1996 and 1997, Paradigm
purchased product with a value of $3,237,000, $6,111,000 and $2,667,000,
respectively, from NKK Corporation ("NKK"). There was no amount due NKK at
December 31, 1996 or December 31, 1997.
 
  In April 1995, NKK and Paradigm modified their previous technology license
and development agreements. This 1995 agreement provides for payment of
royalties to Paradigm by NKK on certain quantities of 1M SRAM's sold and, with
certain exceptions, cancels further obligations of each party to deliver
technology improvements or design updates to the other.
 
  On April 28, 1995, pursuant to certain agreements with certain of Paradigm's
stockholders, Atmel Corporation ("Atmel") acquired 42,500 shares of common
stock from Paradigm, 30,000 shares of common stock from certain stockholders
of Paradigm who had been unsecured creditors of Paradigm as of the
reorganization, and 12,805 shares of common stock from Paradigm's equipment
lessors all of which shares were purchased at a price of $80.00 per share (the
"Atmel Stock"). Atmel also acquired certain warrants to purchase 17,500 shares
of common stock at an exercise price of $10.00 per share, for a purchase price
of $70.00 per share subject to the warrants. In connection with these
transactions, Paradigm entered into an Agreement with Atmel (the "Stock
Purchase Agreement") pursuant to which Atmel agreed to certain transfer
restrictions for a period of three years. Atmel agreed not to increase its
beneficial ownership above 19.9% of the voting power of Paradigm on a fully
diluted basis for a period of five years from the date of the Stock Purchase
Agreement. The foregoing restrictions terminate on the date on which a person
or entity acquires more than 50% of the voting power of Paradigm. On April 28,
1995, Atmel also entered into a Licensing and Manufacturing Agreement (the
"Agreement") with Paradigm. This Agreement provides Atmel with a nonexclusive,
royalty bearing license to manufacture, use and sell certain of Paradigm's
products. The royalty fee is based on a percentage of the average selling
price of the products sold. In addition, under the Agreement, a certain wafer
manufacturing capacity per week has been made available to Paradigm by Atmel.
The Agreement does not include a purchase commitment by Paradigm. However, to
the extent Paradigm provides Atmel with its three-month demand forecast, it is
committed to purchase the three-month forecasted quantities. No obligation to
purchase wafers existed as of December 31, 1997. The price of the wafers has
been fixed at the current fair market value. The Agreement expires on April
28, 2000. There were no purchases from Atmel in 1997, and there was no amount
due Atmel at December 31, 1997. The value of product purchased from Atmel in
the year ended December 31, 1996 was $429,000 of which $140,000 is included in
the accounts payable, related party balance at December 31, 1996.
 
  Alliant Partners LLP. James L. Kochman, a director of Paradigm, is a partner
of Alliant Partners LLP ("Alliant") (formerly Bentley, Hall, Von Gehr
International), an investment banking firm which performed investment banking
services for Paradigm during the twelve (12) months ended December 31, 1997.
Compensation to Alliant during 1997 was $6,000, which did not exceed 5% of
Alliant's consolidated gross revenues for its most recent fiscal year.
Paradigm retained Alliant to render a fairness opinion letter in connection
with the Merger. Alliant may also perform investment banking services for
Paradigm from time to time in the future.

COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT
 
  Section 16(a) of the Securities Exchange Act of 1934 (the "Exchange Act")
and the rules of the Securities and Exchange Commission (the "Commission")
thereunder require Paradigm's directors, executive officers and 10% beneficial
owners to file reports of their ownership and changes in ownership of Common
Stock with the Commission. Personnel of Paradigm generally prepare these
reports on the basis of information obtained from Paradigm's directors and
officers. Based on such information, Paradigm believes that all reports
required by Section 16(a) of the Exchange Act to be filed by its directors and
executive officers during the last fiscal year were filed on time, except that
Dennis McDonald inadvertently filed a Form 3 late relating to the acquisition
of Common Stock in January 1997, James Boswell inadvertently filed a Form 3
and Form 5 late relating to grants of nonstatutory stock options in July 1997
and November 1997. Although each is a greater than 10% beneficial owner of
Paradigm's Common Stock, Paradigm believes that Vintage Products, Inc. and
Lyford Ltd. made no filings required by Section 16(a) of the Exchange Act.
 
BOARD REPORT ON COMPENSATION
 
  The Executive Compensation Committee of the Paradigm Board did not meet in
1997. Due to the poor financial performance of Paradigm in 1997, all executive
officers voluntarily reduced their salary during 1997 in exchange for stock
option grants with an exercise price set at the then fair market value, and an
aggregate exercise price equal to the amount of such reduction, and no bonuses
were paid.
 
  Base salary for Mr. Gulett, former President and Chief Executive Officer,
for fiscal 1997 was $243,408, consisting of (i) $255,000 in base salary that
was negotiated as part of his Employment Agreement dated August 26, 1996, as
amended, less (ii) $25,500 of salary waived by Mr. Gulett for a six month
period, with part of such period continuing into fiscal 1998. The factors and
criteria used to set Mr. Gulett's compensation were (i) his individual
performance and contributions to the Company; (ii) the financial results of
the Company, including pre-tax profit; and (iii) the compensation of executive
officers employed by companies in similar industries with similar revenue
levels.
 
  Effective February 3, 1997, and March 5, 1998, the Board approved the
repricing of Mr. Gulett's stock options covering 4,000 and 6,500 shares,
respectively (restated for the ten-for-one reverse stock split effectuated on
May 1, 1998), as described in the Ten-Year Option Repricings Table. Effective
August 18, 1998, the Board approved an option grant to Mr. Gulett to purchase
2,550 shares (restated for the ten-for-one reverse stock split effectuated on
May 1, 1998) of Common Stock in connection with his waiver of $25,500 in
salary.
 
  In February 1997, the Paradigm Board agreed that additional incentives were
needed since many of Paradigm's employees and directors held stock options
with grants priced significantly higher than the fair market value of Paradigm
Common Stock. Therefore, Paradigm implemented a program whereby option holders
could exchange higher priced option shares for the same number of lower priced
option shares. The new options were issued on February 3, 1997 at the then
fair market value of $20.625 per share. Executive officers must have remained
active on Paradigm's payroll until August 3, 1997 to exercise their new
options. All executive officers and directors holding options were eligible to
participate in this program. Data for executive officers and directors who
were eligible to reprice options are shown in the first table entitled "Ten
Year Option Repricings."
 
  In December 1997, certain of Paradigm's current executive officers received
stock options in amounts which are set forth in Paradigm's Summary
Compensation Table in this Joint Proxy Statement/Prospectus. Stock options
were granted to these executive officers on the basis of each such executive's
anticipated future performance and contributions to Paradigm. The stock option
grants were designed to align more closely the interest of the executives with
the interests of the stockholders.
 
  Since the compensation of Paradigm's executive officers does not exceed
$1,000,000 for any single officer, Paradigm does not have a policy regarding
qualifying compensation under Section 162(m) of the Code.

                            THE STOCK PLAN PROPOSAL
 
            APPROVAL OF THE AMENDMENT TO THE 1994 STOCK OPTION PLAN
 
INTRODUCTION
   
  The 1994 Stock Option Plan of Paradigm was adopted by the Paradigm Board in
June 1994 and approved by the stockholders at the 1996 Annual Meeting. In
April 1998, the Paradigm Board amended and restated the 1994 Stock Option Plan
(the "1994 Plan") to (i) increase the number of shares available for grant
thereunder to employees, independent contractors and advisors by 100,000
shares (after the Reverse Stock Split described in the Reverse Stock Split
Proposal), which would be available for incentive stock options subject to
approval by stockholders, (ii) increase the number of shares available for
grant thereunder to non-employee directors by 15,000 shares (after the Reverse
Stock Split described in the Reverse Stock Split Proposal), which would be
available for nonqualified statutory options, (iii) provide that non-employee
directors who are employed by stockholders of the Combined Company who hold
more than 5% of the outstanding shares of common stock of the Combined Company
shall not be eligible to receive non-discretionary grants of stock options
under the 1994 Plan and (iv) increase the number of shares that can be made
subject to options in any fiscal year to 35,000 (after the Reverse Stock
Split).     
 
  The text of the 1994 Plan is set forth in Annex D of this Joint Proxy
Statement/Prospectus. The following is a brief summary of portions of the 1994
Plan's features and does not purport to be complete. It is subject to and
qualified in its entirety by reference to Annex D.
 
PURPOSE OF THE PROPOSED AMENDMENTS TO THE 1994 PLAN
 
  After the Effective Time, the post-Merger entity will require additional
shares of common stock to grant stock options to current and new employees and
new non-employee directors in the future. The increase in the number of shares
of common stock available for grant under the 1994 Plan will provide
sufficient shares to enable management to grant such options in the
foreseeable future.
 
SHARES SUBJECT TO THE 1994 PLAN
   
  Prior to the amendment and restatement of the 1994 Plan, there are 149,800
shares of Paradigm Common Stock (approximately 9,987 shares after the Reverse
Stock Split described in the Reverse Stock Split Proposal) authorized for
option grants. Upon approval of this amendment by the stockholders, there will
be a total of 264,800 shares authorized under the 1994 Plan (after the Reverse
Stock Split described in the Reverse Stock Split Proposal). The authorized
shares issuable in connection with the 1994 Plan are subject to adjustment in
the event of stock splits, stock dividends and other situations.     
   
  As of June 16, 1998, Paradigm had options outstanding under the 1994 Plan to
purchase an aggregate of 133,834 shares of Paradigm Common Stock
(approximately 8,922 shares after the Reverse Stock Split described in the
Reverse Stock Split Proposal), at an exercise price of $3.187 per share, or a
weighted average per share exercise price of $3.187. If any option granted
under the 1994 Plan expires or terminates for any reason without having been
exercised in full, then the unpurchased shares subject to that option will
once again be available for additional option grants. As of June 16, 1998, a
total of 4,250 (approximately 284 shares after the Reverse Stock Split
described in the Reverse Stock Split Proposal) shares of Paradigm Common Stock
were available for future issuance under the 1994 Plan to executive officers
and employees and a total of 11,250 shares of Paradigm Common Stock
(approximately 750 shares after the Reverse Stock Split described in the
Reverse Stock Split Proposal) were available for future issuance under the
1994 Plan to non-employee directors.     
 
PARTICIPANTS
 
  Any person who is an employee (including an officer or director) of, or
independent contractor or advisor to, Paradigm is eligible to receive options
under the 1994 Plan. Optionees will be selected by the Stock Option Committee
or in the alternative, the Paradigm Board.
 
                                      87
<PAGE>
 
  The 1994 Plan also provides for automatic grants for non-employee directors.
Non-employee directors will automatically receive nonstatutory options to
purchase 1,563 shares of Paradigm Common Stock (after the Reverse Stock Split
described in the Reverse Stock Split Proposal) for every regular annual
meeting after which they remain on the Board. Each new non-employee director
who joins the Paradigm Board is automatically granted an option to purchase
6,250 shares of Paradigm Common Stock (after the Reverse Stock Split described
in the Reverse Stock Split Proposal) upon the date on which such person first
becomes a non-employee director. The non-employee director options will have
ten (10) year terms and will be exercisable ratably at twenty-five percent
(25%) a year from the date of the annual meeting of stockholders on which date
the options are granted.
 
FEDERAL TAX INFORMATION
 
  The following discussion of the federal income tax consequences of the 1994
Plan is intended to be a summary of applicable federal law. Foreign, state and
local tax consequences may differ. Because the federal income tax rules
governing options and related payments are complex and subject to frequent
change, optionees are advised to consult their tax advisors prior to exercise
of options or dispositions of stock acquired pursuant to option exercise.
 
  Incentive Stock Options ("ISOs") and Nonqualified Stock Options ("NSOs") are
treated differently for federal income tax purposes. ISOs are intended to
comply with the requirements of Section 422 of the Code. NSOs need not comply
with such requirements.
 
  An employee is not taxed on the grant or exercise of an ISO. The difference
between the exercise price and the fair market value of the shares on the
exercise date will, however, be a preference item for purposes of the
alternative minimum tax. If an optionee holds the shares acquired upon
exercise of an ISO for at least two years following grant and at least one
year following exercise, the optionee's gain, if any, upon a subsequent
disposition of such shares is taxed at capital gains rates. The measure of the
gain is the difference between the proceeds received on disposition and the
optionee's basis in the shares (which generally equals the exercise price). If
an optionee disposes of stock acquired pursuant to exercise of an ISO before
satisfying the one- and two-year holding periods described above, the optionee
will recognize both ordinary income and capital gain in the year of
disposition. The amount of the ordinary income will be the lesser of (i) the
amount realized on disposition less the optionee's adjusted basis in the stock
(usually the exercise price) or (ii) the difference between the fair market
value of the stock on the exercise date and the exercise price. The balance of
the consideration received on such a disposition will be taxed at capital
gains rates if the stock had been held for at least one year following
exercise of the ISO. Paradigm is not entitled to an income tax deduction on
the grant or exercise of an ISO or on the optionee's disposition of the shares
after satisfying the holding period requirement described above. If the
holding periods are not satisfied, Paradigm will be entitled to a deduction in
the year the optionee disposes of the shares, in an amount equal to the
ordinary income recognized by the optionee.
 
  An optionee is not taxed on the grant of an NSO. On exercise, however, the
optionee recognizes ordinary income equal to the difference between the
exercise price and the fair market value of the shares on the date of
exercise. Paradigm is entitled to an income tax deduction in the year of
exercise in the amount recognized by the optionee as ordinary income. Any gain
on subsequent disposition of the shares is capital gain. Paradigm does not
receive a deduction for this gain.
 
VOTE NECESSARY TO APPROVE THE PROPOSAL
 
  Each holder of Paradigm Common Stock is entitled to one vote per share held.
The holders of a majority of the shares of the Paradigm Common Stock issued
and outstanding shall constitute a quorum. The affirmative vote of holders of
a majority of the outstanding shares of Common Stock voting on the Stock Plan
Proposal at the duly convened Paradigm Annual Meeting is required for approval
of the amendment to increase the number of shares issuable under the 1994
Plan. In the event that a quorum is not present or represented at the Paradigm
Annual Meeting, the stockholders entitled to vote at the meeting present in
person or by proxy shall have power
 
                                      88
<PAGE>
 
to adjourn the Paradigm Annual Meeting until a quorum shall be present or
represented. Proxies solicited by the Paradigm Board will be voted for
approval of the Stock Plan Proposal, unless otherwise instructed.
 
  A stockholder voting through a proxy who abstains with respect to approval
of the Stock Plan Proposal shall be considered to have cast a negative vote
with respect to the Stock Plan Proposal, but shall be treated as present and
entitled to vote on the approval of the other Proposals presented to the
stockholders at the Paradigm Annual Meeting; provided, however, that a
stockholder (including a broker) who does not give authority to a proxy to
vote on the approval of the other Proposals shall not be considered present
and entitled to vote on the other Proposals.
 
  In the event that the Stock Plan Proposal is approved by the Paradigm
stockholders and the Merger Proposal and Issuance Proposal is not approved by
the Paradigm stockholders, Paradigm will take no action to implement the Stock
Plan Proposal.
 
RECOMMENDATION OF THE PARADIGM BOARD
 
  The Paradigm Board recommends a vote "FOR" the proposal to amend the 1994
Plan to increase the number of shares issuable thereunder. Unless a contrary
choice is specified, proxies solicited by the Paradigm Board will be voted FOR
approval of the amendment to the 1994 Plan to increase the number of shares
issuable thereunder.
 
   THE PARADIGM BOARD RECOMMENDS A VOTE "FOR" THE APPROVAL OF THE STOCK PLAN
                                   PROPOSAL.

                    RATIFICATION OF INDEPENDENT ACCOUNTANTS
   
  The Board has approved the retention of PricewaterhouseCoopers LLP as
independent accountants for Paradigm until revoked by further action.
PricewaterhouseCoopers LLP (formerly Price Waterhouse LLP) has been Paradigm's
independent accountants since June 1994.     
   
  The stockholders are asked to ratify the designation of
PricewaterhouseCoopers LLP as independent accountants for Paradigm for the
fiscal year ending December 31, 1998. A representative of
PricewaterhouseCoopers LLP is expected to be present at the Paradigm Annual
Meeting to make a statement if he or she desires to do so, and such
representative is expected to be available to respond to appropriate
questions.     
   
  Should the stockholders fail to ratify the designation of
PricewaterhouseCoopers LLP as independent accountants, retention of the firm
for the fiscal year ending December 31, 1998 will be reconsidered by the
Board. If the Merger is consummated, then historical financial statements of
IXYS shall become the historical financial statements of the Combined Company
following the Merger. PricewaterhouseCoopers LLP will be the independent
accountants of the Combined Company.     
   
  Unless marked to the contrary, proxies received will be voted "FOR"
ratification of the designation of PricewaterhouseCoopers LLP as independent
accountants for Paradigm's fiscal year ending December 31, 1998.     
 
  Ratification of Paradigm's independent accountants requires the affirmative
vote of holders of a majority of the outstanding shares of Paradigm Common
Stock present in person or by proxy at the Paradigm Annual Meeting that vote
on such proposal.
 
           THE BOARD OF DIRECTORS OF PARADIGM UNANIMOUSLY RECOMMENDS
       A VOTE "FOR" RATIFICATION OF PARADIGM'S INDEPENDENT ACCOUNTANTS.

                         THE IXYS CERTIFICATE PROPOSAL
 
  The Certificate of Incorporation of IXYS Corporation (the "IXYS
Certificate") currently provides that any merger of IXYS with or into any
other corporation in which the stockholders of IXYS own less than 50% of
IXYS's voting power immediately after such merger shall be considered a
liquidation under the IXYS Certificate. In a liquidation, the holders of IXYS
Preferred Stock would be entitled to be paid their respective liquidation
preferences, which would require the payment of $37,556,000 in cash. Although
the stockholders of IXYS will own more than 50% of the voting power of the
Combined Company immediately after the Merger, because of the structure of the
transaction, they will not own any shares of IXYS itself after the Merger,
which will instead be owned by the Combined Company. The structure was
selected to permit the stockholders of IXYS to hold shares in a public company
and to avoid merging IXYS directly into Paradigm, whereby IXYS would disappear
as a corporation. IXYS and Paradigm do not intend by virtue of the Merger to
cause the payment of the liquidation preferences of the IXYS Preferred Stock.
To avoid any inference that the Merger could be construed as a liquidation
under the IXYS Certificate, it is proposed that the following Paragraph e. be
added at the end of Section 3 of Paragraph E. of Article IV of the IXYS
Certificate:
 
  "e. Notwithstanding anything in this Section 3 to the contrary, neither a
merger of the Corporation with Paradigm Enterprises, Inc., a Delaware
corporation, nor a transfer of voting power in connection with such merger
shall be considered a liquidation under this Section."
 
  By approving the foregoing amendment to the IXYS Certificate, the
stockholders of IXYS will also approve a change in the name of IXYS to "IXYS
USA, Inc." The Combined Company will be renamed "IXYS Corporation" upon
consummation of the Merger.
 
VOTE NECESSARY TO APPROVE THE PROPOSAL
 
  Each holder of IXYS Capital Stock is entitled to one vote per share held.
The holders of a majority of the issued and outstanding shares of IXYS Capital
Stock shall constitute a quorum. The affirmative vote of holders of a majority
of the outstanding shares of IXYS Capital Stock, voting together as a single
class, and the affirmative vote of a majority of the outstanding shares of
IXYS Preferred Stock, voting together as a single class, are required for
approval of the IXYS Certificate Proposal. In the event that a quorum is not
present or represented at the IXYS Special Meeting, the stockholders entitled
to vote at the meeting present in person or by proxy shall have power to
adjourn the IXYS Annual Meeting until a quorum shall be present or
represented.
 
  A stockholder voting through a proxy who abstains with respect to approval
of the IXYS Certificate Proposal shall be considered to have cast a negative
vote with respect to the IXYS Certificate Proposal, but shall be treated as
present and entitled to vote on the Merger Proposal at the IXYS Special
Meeting; provided, however, that a stockholder (including a broker) who does
not give authority to a proxy to vote on approval of the Merger Proposal shall
not be considered present and entitled to vote on the Merger Proposal.
 
RECOMMENDATION OF THE IXYS BOARD
 
  The IXYS Board recommends a vote "FOR" the proposal to amend IXYS'
Certificate of Incorporation to avoid any inference that the Merger could be
construed as a liquidation under the IXYS Certificate of Incorporation. Unless
a contrary choice is specified, proxies solicited by the IXYS Board will be
voted FOR approval of the IXYS Certificate Proposal.
 
    THE IXYS BOARD RECOMMENDS A VOTE "FOR" APPROVAL OF THE IXYS CERTIFICATE
                                   PROPOSAL

         UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION
 
  The following unaudited pro forma condensed combined financial statements
give effect to the proposed merger of Paradigm and IXYS using the purchase
method of accounting in accordance with generally accepted accounting
principles. IXYS is considered the accounting acquiror. The unaudited pro
forma condensed combined financial statements are based on the respective
historical financial statements which are included elsewhere in this Joint
Proxy Statement/Prospectus. The unaudited pro forma condensed combined balance
sheets assume that the Merger took place on March 31, 1998 and combine
Paradigm's March 31, 1998 historical balance sheet with IXYS' March 31, 1998
historical consolidated balance sheet. The unaudited pro forma condensed
combined statements of operations assume that the Merger took place as of
January 1, 1997 for the twelve months ended December 31, 1997 and combine IXYS
consolidated statements of operations for the three months ended March 31,
1997 (unaudited) and the nine months ended December 31, 1997 (unaudited) with
Paradigm's historical results of operations for the twelve months ended
December 31, 1997. The unaudited pro forma condensed combined statements of
operations for the three months ended March 31, 1998 combine Paradigm's
condensed statement of operations for the three months ended March 31, 1998
(unaudited) with IXYS' condensed consolidated statement of income for the same
period (unaudited). The unaudited pro forma condensed combined financial
statements are based on the estimates and assumptions set forth in the notes
to such statements. The pro forma adjustments are based on a preliminary
valuation of Paradigm that has yet to be finalized, made in connection with
the development of the pro forma information for illustrative purposes to
comply with the disclosure requirements of the Commission. The pro forma
adjustments included in the unaudited pro forma condensed combined financial
information may be revised upon the finalization of the valuation of the net
assets acquired by IXYS. The unaudited pro forma condensed combined financial
statements do not purport to be indicative of the results of operations for
future periods or the combined financial position or results that would have
been realized had the companies been a single entity during these periods.
These unaudited pro forma condensed combined financial statements should be
read in conjunction with the historical consolidated financial statements and
the related notes thereto of Paradigm and IXYS, which are included elsewhere
herein. See "Index to Financial Statements."

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED STATEMENTS OF OPERATIONS:
 
(1) Adjustment reflects the amortization of the amount of the purchase price
    allocated to identified intangible assets over 12 months ending December
    31, 1997 and 3 months ending March 31, 1998. Intangibles are being
    amortized over 2 years.
   
(2) Shares used in the per share calculation reflect 7.1 million shares issued
    to IXYS stockholders as if they were outstanding from the beginning of
    each period presented and Paradigm shares following the reverse stock
    splits. IXYS shares are calculated using 111,409,363 shares of preferred
    stock and 72,211,873 shares of common stock converted at the exchange
    ratio of 0.038876 per share.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED BALANCE SHEET:
 
(1) Reflects allocation of a portion of the estimated purchase price of $3.6
    million to identified intangible assets and the related deferred tax
    liability. The total purchase price of $3.6 million was calculated based
    on the market price of Paradigm Common Stock at the assumed date of the
    transaction ($0.875 per share at June 16, 1998) multiplied by Paradigm's
    total stock outstanding (1,779,401 shares of common stock and 1,394,172
    shares of common stock issuable upon conversion of preferred stock) and
    includes approximately $800,000 of transaction related costs born by IXYS.
    The excess of the purchase price over the net assets of Paradigm has been
    allocated to current products ($182), workforce and other identified
    intangibles ($211), and in-process research and development ($1,108).
    IXYS' management estimates that the net book value of Paradigm's fixed
    assets approximate their fair value at the purchase date.
(2) Reflects the conversion of IXYS mandatorily redeemable convertible
    preferred stock into IXYS Common Stock at the date of the transaction.
(3) Reflects the impact on stockholders' equity of the anticipated write-off
    of in-process research and development in the amount of $1,108, net of
    income tax effects. Amount is initially recorded in paid-in capital and
    then is expensed into accumulated deficit.

                               PARADIGM BUSINESS
 
  The discussion in this Joint Proxy Statement/Prospectus contains forward-
looking statements which involve risks and uncertainties. Paradigm's actual
results could differ materially from those discussed in the forward-looking
statements. Factors that could cause or contribute to such differences
include, without limitation, those discussed in this section and in the
sections entitled "Risk Factors" and "Paradigm Management's Discussion and
Analysis of Financial Condition and Results of Operations," as well as those
discussed elsewhere in this Joint Proxy Statement/Prospectus.
 
GENERAL
 
  Paradigm designs and markets high speed, high density static random access
memory ("SRAM") semiconductor devices to meet the needs of advanced
telecommunications devices, networks, workstations, high performance PCs,
advanced modems and complex military/aerospace applications. Paradigm focuses
on high performance, 10 nanosecond ("ns") and faster SRAMs. For the year ended
December 31, 1997, 10ns and faster SRAMs accounted for approximately 49% of
Paradigm's sales. Using a combination of innovative process architecture and
design know-how, Paradigm was one of the first companies to introduce high
speed CMOS SRAMs for three successive generations of product densities: 256
kilobit ("K"), one megabit ("M"), and 4M. Paradigm's customers in 1997
included Iomega, IKOS, Samsung and Motorola.
 
RECENT DEVELOPMENTS
 
  The SRAM business is highly cyclical and has been subject to significant
downturns at various times that have been characterized by diminished product
demand, production overcapacity, and accelerated erosion of average selling
prices. During the latter part of 1995 continuing into 1996, 1997 and the
first three months of 1998, the market for certain SRAM devices experienced an
excess supply relative to demand which resulted in a significant downward
trend in prices.
 
  The selling prices that Paradigm is able to command for its products are
highly dependent on industry-wide production capacity and demand. In this
regard, Paradigm did experience rapid erosion in product pricing in 1996, 1997
and during the first three months of 1998 which was not within the control of
Paradigm. Paradigm could continue to experience a downward trend in pricing
which could adversely affect Paradigm's operating results.
 
  Paradigm's recent operations have consumed substantial amounts of cash.
During 1997, Paradigm completed the private placement of Series A Preferred
Stock, Series B Preferred Stock, and Series C Preferred Stock for aggregate
net proceeds of approximately $4,673,000. Paradigm believes that it will
require additional cash infusion from similar private placements of equity or
other sources of liquidity, such as asset sales and equipment financing to
meet Paradigm's projected working capital and other cash requirements. The
sale of additional equity or other securities could result in additional
dilution to Paradigm's stockholders. There can be no assurance that such
additional financing, if required, can be obtained on acceptable terms, if at
all.
 
  As a result of these circumstances, Paradigm's independent accountants'
opinion on Paradigm's December 31, 1997 financial statements includes an
explanatory paragraph indicating that these matters raise a substantial doubt
about Paradigm's ability to continue as a going concern.
 
  On March 6, 1998, Paradigm entered into a definitive merger agreement
providing for the acquisition of all of the outstanding capital stock of IXYS
Corporation ("IXYS") in exchange for Common Stock of Paradigm. The exchange
ratio in the Merger for the IXYS equity securities will be the greater of two
ratios. The first ratio provides that upon the Merger the holders of equity
securities of IXYS hold 95% of the fully diluted capitalization of the
combined company and that the holders of equity securities of Paradigm will
hold 5% of the fully diluted capitalization of the combined company. (As used
herein, fully diluted capitalization means
 
                                      95
<PAGE>
 
the sum of the number of shares of common stock outstanding and issuable upon
exercise or conversion of all outstanding preferred stock, warrants, options
and other rights.) The second ratio provides that the value associated with
the fully diluted capitalization of IXYS, at the time of the consummation of
the Merger, be at least $150 million, based on an average of the closing
prices of Paradigm's Common Stock prior to Paradigm's stockholders meeting.
Consummation of the Merger requries the approval of Paradigm's and IXYS'
stockholders and various regulatory agency approvals. If approved, the
transaction is anticipated to be accounted for as a purchase of Paradigm by
IXYS for financial reporting purposes.
 
  On May 1, 1998, Paradigm's stockholders approved a ten-for-one reverse stock
split of Paradigm's common stock, such that every ten shares shall be combined
into one share of common stock. All prior period common shares and per share
data in this Joint Proxy Statement/Prospectus have been restated to reflect
this reverse stock split.
 
INDUSTRY BACKGROUND
 
  Virtually all digital electronic systems, including cellular telephones,
workstations, PCs and modems, contain memory devices. Over the past decade,
the drive to reduce the size and increase the speed and functionality of
electronic systems has required concurrent increases in the density and speed
of memory devices used in these systems. The most widely used memory devices
are dynamic random access memories ("DRAMs") and SRAMs. DRAMs are commercially
available with higher densities than SRAMs, while SRAMs generally are capable
of significantly higher speeds than DRAMs of comparable density. SRAMs achieve
this speed advantage principally by incorporating more transistors in each
memory cell, rendering SRAMs larger and more costly to manufacture. Until
recently, DRAMs have produced acceptable performance levels at a lower cost
and reduced size compared to SRAMs. However, the increased computing speeds of
digital signal processors contained in advanced telecommunications equipment
and recently introduced processors, such as Intel's Pentium and the PowerPC,
have exceeded the ability of DRAMs to provide timely access to data. For
example, to take advantage of the significantly increased performance
capabilities of these new processors in high performance PCs, SRAMs are often
used as cache memory between the processor and the DRAM main memory. The cache
memory stores the most frequently or most recently used data from the DRAM
main memory, enabling quicker access by the processor. When SRAMs are used to
provide access to a high percentage of the information the processor requests,
data access speeds can be greatly enhanced.
 
  The vast majority of SRAMs currently sold are industry standard asynchronous
SRAMs that have only relatively simple interface logic and are required to
operate only at normal commercial temperatures. Synchronous SRAMs, which
operate at the same clock speed as the processor, are more complex and
difficult to produce than asynchronous SRAMs because they combine SRAM memory
with additional logic. Synchronous burst mode SRAMs permit high-end
processors, such as the Pentium and PowerPC, to access data more quickly by
allowing data bits to be transferred in blocks rather than one bit at a time.
Both synchronous and asynchronous SRAMs vary in performance features, such as
speed, density and temperature tolerance, which enable them to support various
high-end applications. In addition, the demand for reduced power consumption
in electronic products has resulted in an increasing demand for low voltage
SRAM devices.
 
  Dataquest Incorporated, an information technology research firm, estimates
that the worldwide market for SRAM products will grow from $6.7 billion in
1996 to $8.9 billion in 1999, with the market for sub-20ns SRAMs growing from
$2.0 billion to $2.5 billion over the same period. In addition to high
performance PCs, SRAMs are used in a variety of other electronics products. In
commercial communications, SRAMs are used in both cellular base stations and
digital cellular telephones. SRAMs are also increasingly used in high speed
communication networks, such as Ethernet and FDDI-based networks. In military
and aerospace systems, SRAMs can also provide the high performance memory
required by fast military processors. For example, high speed military
computers utilize high performance SRAMs in pattern recognition and command,
control and communication applications embedded in today's advanced electronic
weapons, planes and satellites.

PARADIGM'S PRODUCTS
 
  Paradigm designs, manufactures and sells a broad range of SRAM products with
various density, speed, configuration, temperature range and packaging options
for a wide range of commercial, industrial and military applications.
Paradigm's products range in density from 256K to 4M. Paradigm's fastest
products currently achieve 7ns access times, and for the year ended December
31, 1997, 10ns and faster SRAMs accounted for 49% of Paradigm's sales. The
majority of Paradigm's products are available in two levels of power
consumption, standard and low, and three temperature ranges, commercial,
industrial and military. Paradigm also offers its products in a wide variety
of packaging options to accommodate various product features and cost
considerations. Paradigm designs its SRAM packages and pinouts to meet the
standards prescribed by the Joint Electron Device Engineering Council
("JEDEC").
 
  Asynchronous SRAMs. Paradigm's asynchronous SRAM products include high speed
256K, 1M and 4M CMOS SRAMs. They are available in a variety of configurations
and commercial and industrial temperature range versions, as well as military
versions manufactured to comply with the most recent military specifications.
 
  SRAM Modules. Paradigm offers SRAM modules in which multiple SRAMs are
connected and grouped on a printed circuit board and sold as a single unit.
Paradigm module offerings are designed to support the specific needs of the PC
cache market and the requirements for JEDEC standard SRAM modules. Paradigm's
PC cache module offerings include Intel COAST compliant modules and modules
which support PowerPC CHRP based designs. The JEDEC standard module product
offerings include modules ranging in size from 750K to 8M. These modules are
used in a variety of applications including networking, communications,
digital signal processing ("DSP") boards and memory testers.
 
  Products Under Development. Timely development and introduction of new
products are essential to maintaining Paradigm's competitive position.
Paradigm works closely with leading electronics manufacturers in order to
anticipate and develop future generations of high performance SRAMs required
by these customers. Paradigm's current design development objectives include
very fast SRAM products for the telecommunications, networking and
military/aerospace industries. Products currently under development include:
asynchronous, low voltage and high-speed SRAMs; and special configuration
SRAMs for cellular phone and modem applications. In addition, by working
closely with customers, Paradigm is developing a line of module offerings.
Paradigm believes that these modules will provide high quality, high value
SRAM-based industry standard products, as well as custom solutions. In
addition to new product development, Paradigm is focused on redesigning
existing products to reduce manufacturing costs, increase yields, and increase
the speeds of its products.
 
  The SRAM business is highly cyclical and has been subject to significant
downturns at various times that have been characterized by diminished product
demand, production over-capacity and accelerated erosion of average selling
prices. During the latter part of 1996 and throughout 1997, the market for
certain SRAM devices experienced an excess supply relative to demand which
resulted in a significant downward trend in prices. Paradigm expects such
downward price trend to continue. See "Risk Factors--Semiconductor Industry;
SRAM Market."
 
  The selling prices that Paradigm is able to command for its products are
highly dependent on industry-wide production capacity and demand. In this
regard, Paradigm did experience rapid erosion in product pricing during 1996
and 1997 which was not within the control of Paradigm. Paradigm could continue
to experience a downward trend in pricing which could adversely effect
Paradigm's operating results. See "Risk Factors--Semiconductor Industry; SRAM
Market."
 
  Paradigm's future success will depend, in part, on its ability to offset
expected price erosion through manufacturing cost savings, yield improvements
and developing and introducing on a timely basis new products and enhanced
versions of existing products which incorporate advanced features and command
higher prices.

CUSTOMERS AND APPLICATIONS
 
  Recent market trends, such as the rapid expansion of telecommunications,
graphics, multimedia and networking applications and the proliferation of
high-end workstations and PCs, have resulted in significant demand for high
performance SRAMs. Paradigm has targeted this higher performance segment of
the SRAM market, where it believes critical performance criteria such as speed
and temperature tolerance are more highly valued.
 
  For the year ended December 31, 1997, Paradigm's sales of products to
Samsung, IKOS, All American and Iomega accounted for 16%, 16%, 15% and 10% of
sales, respectively.
 
SALES AND MARKETING
 
  Paradigm sells its products in North America through a combination of a
direct sales force, independent sales representatives and distributors. Direct
sales personnel are responsible for calling on key accounts in North America
and coordinating the activities of Paradigm's sales representatives. Paradigm
has a sales manager in each of its regional sales offices in Dallas, Chicago
and Milpitas. Paradigm sells its products in Asia and Europe through a network
of distributors and independent sales representatives. Paradigm intends to
expand the size of its direct sales force and the number of outside sales
representatives to provide additional customer service and broaden its
customer base.
 
  Paradigm's sales representatives and distributors are not subject to minimum
purchase requirements and can discontinue marketing Paradigm's products at any
time. Paradigm's distributors are permitted to return to Paradigm any or all
of the products purchased by them and are offered price protection. As is
standard in the semiconductor industry, distributors are granted a credit for
the difference, at the time of a price reduction, between the price they were
originally charged for the products in inventory and the reduced price which
Paradigm subsequently charges distributors. From time to time, distributors
are also granted credit on an individual basis for Company-approved price
reductions on specific transactions, usually to meet competitive prices.
Paradigm believes that its relations with it sales representatives and
distributors are good.
 
  Paradigm believes that customer service and technical support are important
competitive factors in selling to key customers. Paradigm emphasizes on-time
delivery and quick responses to the demand changes of its customers. Paradigm
has trained employees of its sales representatives and distributors to provide
technical support, with Paradigm technical support engineers available to
provide assistance with more difficult questions.
 
BACKLOG
 
  Paradigm's backlog includes all purchase orders that have been received,
accepted and scheduled for delivery. Paradigm counts in its backlog only those
orders which it believes will be shipped within the next six months. Most
orders in backlog are subject to delivery rescheduling, price renegotiations
and cancellation at the option of the purchaser, usually without penalty. As a
result, although backlog may be useful for scheduling production, it may not
be a reliable measure of sales for future periods. As of December 31, 1997,
Paradigm's backlog was approximately $2.7 million.
 
MANUFACTURING
 
  On November 15, 1996, Paradigm sold its Wafer Fab to Orbit. Paradigm
conducts business with two offshore wafer foundries by delivering written
purchase orders specifying the particular product ordered, quantity, price,
delivery date and shipping terms and, therefore, such foundries are not
obligated to supply products to Paradigm for any specific period, in any
specific quantity or at any specified price, except as may be provided in a
particular purchase order. Reliance on outside foundries involves several
risks, including constraints or delays in timely delivery of Paradigm's
products, reduced control over delivery schedules, quality assurance,
potential costs and loss of production due to seismic activity, weather
conditions and other factors. To the extent a foundry terminates its
relationship with Paradigm, or should Paradigm's supply from a foundry be
 
                                      98
<PAGE>
 
interrupted or terminated for any other reason, Paradigm may not have a
sufficient amount of time to replace the supply of products manufactured by
the foundry. Should Paradigm be unable to obtain a sufficient supply of
products to enable it to meet demand, it could be required to allocate
available supply of its products among its customers. Currently, there is no
shortage of supply, however, until late 1995, there had been a worldwide
shortage of advanced process technology foundry capacity and there can be no
assurance that there will not be such a shortage in the future. If such a
shortage occurs, there can be no assurance that Paradigm will be able to
obtain sufficient foundry capacity to meet customer demand in the future.
Paradigm is continuously evaluating potential new sources of supply. However,
the qualification process and the production ramp-up for additional foundries
could take longer than anticipated, and there can be no assurance that such
sources will be able or willing to satisfy Paradigm's requirements on a timely
basis or at acceptable quality or per unit prices.
 
  Constraints or delays in the supply of Paradigm's products, whether because
of capacity constraints, unexpected disruptions at the current or future
foundries or assembly houses, delays in obtaining additional production at the
existing foundry or in obtaining production from new foundries, shortages of
raw materials, or other reasons, could result in the loss of customers and
other material adverse effects on Paradigm's operating results, including
effects that may result should Paradigm be forced to purchase products from
higher cost foundries or pay expediting charges to obtain additional supply.
See "Risk Factors--Risks Related to the Business of Paradigm."
 
STRATEGIC RELATIONSHIPS
 
  NKK Corporation. Under several technology license and development
agreements, the first two of which were executed in December 1990, Paradigm
and NKK Corporation ("NKK") entered into various product development and
technology licensing relationships, resulting in Paradigm's successful
transfer of its 0.6 micron process technology to NKK's wafer fabrication
facility in Japan. These relationships were modified on April 13, 1995 by an
agreement (the "NKK Agreement") which significantly simplified the
relationship between the parties and substantially ended each party's
obligation to disclose or deliver technological improvements to the other.
Under the NKK Agreement, NKK has agreed to supply Paradigm with a significant
quantity of 1M SRAMs of Paradigm's design each month for a three year period
in exchange for additional and expanded license rights with respect to certain
proprietary technology. However, Paradigm is under no obligation to purchase
the 1M SRAMs under the NKK Agreement. In effect, the NKK Agreement provides
Paradigm with an important, discretionary ability to increase capacity on an
as-needed basis. Therefore, Paradigm's rights under the NKK Agreement will not
be affected if it does not purchase the 1M SRAMs contemplated by the NKK
Agreement. Paradigm began shipping SRAMs produced by NKK during the fourth
quarter of 1995. The NKK Agreement also rescinded NKK's right to restrict
Paradigm from entering into other foundry relationships or granting additional
licenses for Paradigm's products. The NKK Agreement will automatically
terminate upon completion of the joint development work contemplated by the
Agreement and may be terminated upon default by either party. Paradigm
believes that if the NKK Agreement were terminated it would not have a
material adverse effect on Paradigm's results, operations or financial
condition. See "--Factors That May Affect Future Results" and "--Strategic
Relationships; Potential Competition."
 
COMPETITION
 
  The semiconductor industry is intensely competitive and is characterized by
rapidly changing technology, short product life cycles, cyclical oversupply
and rapid price erosion. Paradigm competes with large domestic and
international semiconductor companies, most of which have substantially
greater financial, technical, marketing, distribution and other resources than
Paradigm. Paradigm's principal competitors in the high performance SRAM market
include Motorola and Samsung. Other competitors in the SRAM market include
Alliance Semiconductor, Cypress Semiconductor, Integrated Device Technology,
Integrated Silicon Solution and numerous other large and emerging
semiconductor companies. In addition, other manufacturers can be expected to
enter the high speed, high density SRAM market. In 1995, NKK commenced
production of products using Paradigm's design and process technologies, and
therefore may become a more significant competitor of Paradigm. Paradigm has
also licensed to Atmel the right to produce certain of its SRAM products, and
as a result
 
                                      99
<PAGE>
 
may compete with Atmel with respect to such products. Because both NKK and
Atmel have greater resources than Paradigm and have foundry capacity, any such
competition could adversely affect Paradigm. To the extent that Paradigm
enters into similar arrangements with other companies, it may compete with
such companies as well. See "--Strategic Relationships; Potential Competition"
and "Risk Factors--Risks Related to the Business of Paradigm."
 
  The ability of Paradigm to compete successfully depends on elements outside
its control, including the rate at which customers incorporate Paradigm's
products into their systems, the success of such customers in selling those
systems, Paradigm's protection of its intellectual property, the number,
nature and success of its competitors and their product introductions and
general market and economic conditions. In addition, Paradigm's success will
depend in large part on its ability to develop, introduce and manufacture in a
timely manner products that compete effectively on the basis of product
features (including speed, density, die size, and packaging), availability,
quality, reliability and price, together with other factors including the
availability of sufficient manufacturing capacity and the adequacy of
production yields. There can be no assurance that Paradigm will be able to
compete successfully in the future. See "Risk Factors--Risks Related to the
Business of Paradigm."
 
PATENTS AND LICENSED TECHNOLOGY
 
  Paradigm seeks to protect its proprietary technology by filing applications
to obtain patents in the United States and foreign countries and by
registering its circuit designs pursuant to the U.S. Semiconductor Chip
Protection Act of 1984. Paradigm also relies on trade secrets and confidential
technological know-how in the conduct of its business. As of December 31,
1997, Paradigm held 17 U.S. patents and one Canadian patent, and had four U.S.
and 15 foreign patent applications pending. Paradigm believes that its patent
portfolio strengthens its negotiating position with respect to technology
ownership disputes that may occur in the future.
 
  Paradigm intends to continue to pursue patent, trade secret, and mask work
protection for its semiconductor process technologies and designs. To that
end, Paradigm has obtained certain patents and patent licenses and intends to
continue to seek patents on its inventions, as appropriate. The process of
seeking patent protection can be long and expensive, and there is no assurance
that patents will be issued from currently pending or future applications or
that, if patents are issued, they will be of sufficient scope or strength to
provide meaningful protection or any commercial advantage to Paradigm. In
particular, there can be no assurance that any patents held by Paradigm will
not be challenged, invalidated or circumvented, or that the rights granted
thereunder will provide competitive advantage to Paradigm. Paradigm also
relies on trade secret protection for its technology, in part through
confidentiality agreements with its employees, consultants and third parties.
There can be no assurance that these agreements will be fully effective or
will not be breached, that Paradigm will have adequate remedies for any
breach, or that Paradigm's trade secrets will not otherwise become known to or
independently developed by others. In addition, the laws of certain countries
in which Paradigm's products are or may be developed, manufactured or sold may
not protect Paradigm's products and intellectual property rights to the same
extent as the laws of the United States. See "Risk Factors--Risks Related to
the Business of Paradigm."
 
  There has been substantial litigation regarding patent and other
intellectual property rights in the semiconductor industry. In the future,
litigation may be necessary to enforce patents issued to Paradigm, to protect
trade secrets or know-how owned by Paradigm, or to defend Paradigm against
claimed infringement of the rights of others and to determine the scope and
validity of the proprietary rights of others. Paradigm has from time to time
received, and may in the future receive, communications alleging possible
infringement of patents or other intellectual property rights of others. Any
such litigation could result in substantial cost to and diversion of effort by
Paradigm, which could have a material adverse effect on Paradigm. Further,
adverse determinations in such litigation could result in Paradigm's loss of
proprietary rights, subject Paradigm to significant liabilities to third
parties, require Paradigm to seek licenses from third parties or prevent
Paradigm from manufacturing or selling its products, any of which could have a
material adverse effect on Paradigm. See "Risk Factors--Risks Related to the
Business of Paradigm."

  In December 1990, as part of an agreement terminating a strategic
relationship with AT&T, Paradigm entered into a nonexclusive license agreement
with AT&T giving Paradigm a license to use all AT&T-owned, semiconductor-
related patents over a period of eight years. Under the agreement, Paradigm
agreed to pay AT&T a royalty of 0.75% of revenue for each product produced by
Paradigm. Under the same agreement, Paradigm licensed to AT&T its poly-iso
structure for a similar royalty.
 
  Paradigm has also entered into certain license agreements with NKK. See "--
Strategic Relationships."
 
ENVIRONMENTAL MATTERS
 
  Paradigm believes that compliance with federal, state and local provisions
regulating the discharge of materials into the environment or otherwise
relating to the protection of the environment will not have a material effect
upon its capital expenditures, operations or competitive position.
 
EMPLOYEES
 
  As of December 31, 1997, Paradigm had 21 employees, of whom 2 were engaged
in research and development and engineering, 5 in marketing, sales and
customer support, 6 in manufacturing, 4 in finance and 4 in administration.
Paradigm's employees are not represented by a collective bargaining
organization and Paradigm has never experienced a work stoppage. Paradigm
believes that its employee relations are good. See "Risk Factors--Risks
Related to the Business of Paradigm."
 
PROPERTIES
 
  Paradigm leases its 20,000 square foot principal facility in Milpitas,
California pursuant to a lease that expires in January 2002. Paradigm also has
domestic sales offices in the Chicago and Dallas metropolitan areas. Paradigm
believes that the size of its existing facility is adequate to meet its
current needs.
 
FACTORS THAT MAY AFFECT FUTURE RESULTS
 
  The operations and business prospects of Paradigm are subject to certain
qualifications based on potential business risks faced by Paradigm. This Joint
Proxy Statement/Prospectus should be reviewed in light of the potential
effects of events that may occur as outlined in the risk factors presented in
the section titled "Risk Factors."

   PARADIGM MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS
 
  This Joint Proxy Statement/Prospectus contains forward-looking statements
that involve risks and uncertainties. Paradigm's actual results may differ
materially from the results discussed in such forward-looking statements.
Factors that may cause such a difference include, but are not limited to,
those discussed in "Risk Factors."
 
OVERVIEW
 
  Paradigm was founded in January 1987 and focused its initial development
efforts primarily on high speed 256K and 1M SRAMs, producing its first
prototype product in 1988. In July 1989, Paradigm began operating its wafer
fabrication facility in San Jose, California and in April 1990 shipped its
first commercial products, high speed 256K SRAMs. In July 1990 and October
1993, respectively, Paradigm began shipping 1M SRAMs and limited quantities of
4M SRAMs. On November 15, 1996, Paradigm sold its fabrication facility to
Orbit. See "Sale of Wafer Fabrication Facility."
 
  From its inception through the Paradigm Reorganization in June 1994,
Paradigm incurred substantial operating losses as it developed its technology
and manufacturing processes. During this period, Paradigm incurred significant
indebtedness to fund its operations, including capital expenditures associated
with its wafer fabrication facility. This increasing indebtedness resulted in
a significant increase in interest expense, which negatively impacted cash
flow. In addition, Paradigm incurred operating losses due to manufacturing
inefficiencies and a less than optimal sales mix that was comprised primarily
of customers in lower margin markets. Specifically, prior to the Paradigm
Reorganization, many of Paradigm's suppliers temporarily suspended shipments
or demanded payment in cash prior to delivery of products. In addition, due to
Paradigm's urgent cash needs, it sold the majority of its high performance
SRAM products into lower margin commodity markets, resulting in reduced sales
and lower margins than would otherwise have been achievable. In January 1994,
Paradigm concluded that it could not meet its debt obligations and began to
develop a plan for restructuring its debt and capital structure. See "--
Chapter 11 Reorganization."
 
  Prior to the Paradigm Reorganization, Paradigm's new management team adopted
a strategy of focusing on emerging markets for higher performance asynchronous
and synchronous SRAMs and specialty products. This emphasis on the higher end
of the SRAM market was facilitated by the Paradigm Reorganization, which gave
Paradigm the financial flexibility and time to target high-end markets for its
high performance products. As a result of Paradigm's change in marketing
strategy, Paradigm made a transition from a customer base composed largely of
contract manufacturers to one increasingly represented by market leading
product developers, resulting in increased sales to Paradigm's targeted
markets in the telecommunications, networking, workstation, high performance
PC and military/aerospace industries.
 
  Beginning in late 1995 and continuing through 1997, Paradigm has experienced
significant decreases in average selling prices for certain products. Such
price decreases have had an adverse effect on Paradigm's operating results.
Accordingly, Paradigm's ability to maintain or increase revenues will be
highly dependent upon its ability to increase unit sales volumes of existing
products and to introduce and sell new products in quantities sufficient to
compensate for the anticipated declines in average selling prices of existing
products. Declining average selling prices will also adversely affect
Paradigm's gross margins unless Paradigm is able to reduce its costs per unit
to offset such declines.
 
  Paradigm's recent operations have consumed substantial amounts of cash.
During 1997, Paradigm completed the private placement of Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock for aggregate net
proceeds of approximately $4,673,000. Paradigm believes that it will require
additional cash infusion from similar private placements of equity or other
sources of liquidity, such as asset sales and equipment financing to meet
Paradigm's projected working capital and other cash requirements. Absent
additional cash infusion from private placements of equity or other sources of
liquidity, such as asset sales and
 
                                      102
<PAGE>
 
equipment financing, Paradigm's continued existence is in substantial doubt.
Management does not believe it is likely to achieve any of the alternatives
set forth above. The sale of additional equity or other securities could
result in additional dilution to Paradigm's stockholders. There can be no
assurance that such additional financing, if required, can be obtained on
acceptable terms, if at all.
 
  As a result of these circumstances, Paradigm's independent accountants'
opinion on Paradigm's December 31, 1997 financial statements includes an
explanatory paragraph indicating that these matters raise a substantial doubt
about Paradigm's ability to continue as a going concern.
 
  Management's plans for Paradigm's continued existence is to consummate the
pending merger with IXYS Corporation ("IXYS"). On March 6, 1998, Paradigm
entered into a definitive merger agreement providing for the acquisition of
all of the outstanding capital stock of IXYS in exchange for Common Stock of
Paradigm. The exchange ratio in the Merger for the IXYS equity securities will
be the greater of two ratios. The first ratio provides that upon the Merger
the holders of equity securities of IXYS hold 95% of the fully diluted
capitalization of the combined company and that the holders of equity
securities of Paradigm will hold 5% of the fully diluted capitalization of the
combined company. (As used herein, fully diluted capitalization means the sum
of the number of shares of common stock outstanding and issuable upon exercise
or conversion of all outstanding preferred stock, warrants, options and other
rights.) The second ratio provides that the value associated with the fully
diluted capitalization of IXYS, at the time of the consummation of the Merger,
be at least $150 million, based upon an average of the closing prices of
Paradigm's Common Stock prior to Paradigm's stockholders meeting. Consummation
of the merger requires the approval of Paradigm's and IXYS' stockholders and
various regulatory agency approvals. If approved, the transaction is
anticipated to be accounted for as a purchase of Paradigm by IXYS for
financial reporting purposes.
 
CHAPTER 11 REORGANIZATION
 
  On February 23, 1994, Paradigm entered into a letter of intent with ACMA
Limited ("ACMA") and a letter of intent with National Semiconductor
Corporation ("NSC") to restructure its obligations and provide additional
capital to Paradigm. On March 30, 1994 and pursuant to the ACMA letter of
intent, Paradigm filed in the United States Bankruptcy Court for the Northern
District of California (the "Court") a voluntary petition for reorganization
under Chapter 11 of the U.S. Bankruptcy Code. On April 7, 1994, Paradigm filed
its initial Plan of Reorganization with the Court. On May 24, 1994, after
further negotiations between Paradigm and the Official Committee of Unsecured
Creditors in its bankruptcy proceeding, Paradigm filed its Third Amended Joint
Plan of Reorganization (the "Plan"). On June 7, 1994, the Court confirmed the
Plan, which became effective on June 21, 1994.
 
  The Plan provided for the elimination of a significant portion of Paradigm's
indebtedness and a significant reduction in its interest expense. At the time
of filing of Paradigm's Chapter 11 proceeding, Paradigm's indebtedness,
consisting of bank and other borrowings, capital lease obligations and trade
payables, amounted to $33.9 million, and Paradigm had an accumulated deficit
of $52.7 million. The Plan provided for a substantial restructuring of this
indebtedness through reduction or elimination of certain amounts owed, based
on the order of priority of claims in the Paradigm Reorganization.
Accordingly, bank borrowings and secured borrowings were repaid in full,
capital lease obligations were restructured, and holders of trade payables and
other unsecured borrowings received cash in the amount of 5% of allowed
claims, promissory notes in the amount of 25% of allowed claims, and shares of
Paradigm Common Stock equal to 8.5% of the capital stock of Paradigm on a
fully diluted basis. Under the Plan, the rights and interests of Paradigm's
equity holders at that time were terminated. In addition, pursuant to letters
of intent with Paradigm, ACMA and NSC purchased shares of preferred stock of
Paradigm for an aggregate purchase price of $6.0 million.
 
  In connection with the Paradigm Reorganization, Paradigm's basis of
accounting for financial reporting purposes changed, effective June 21, 1994,
as follows: (i) Paradigm's assets and liabilities reflect a reorganization
value generally approximating the fair value of Paradigm as a going concern on
an unleveraged basis, (ii) Paradigm's accumulated deficit was eliminated, and
(iii) Paradigm's capital structure was adjusted to reflect
 
                                      103
<PAGE>
 
consummation of the Plan. Accordingly, Paradigm's results of operations after
June 20, 1994 are not comparable to the results of operations prior to that
date, and the results of operations for the periods from April 1, 1994 to June
20, 1994 and from June 21, 1994 to December 31, 1994 have not been aggregated.
Further, the financial position of Paradigm on or after June 21, 1994 is not
comparable to its financial position at any date prior thereto.
 
SALE OF WAFER FABRICATION FACILITY
 
  In fiscal 1996, Paradigm adopted a strategy of having its products
manufactured at outside foundries to provide greater flexibility and lower
fixed costs. In that respect, on November 15, 1996, Paradigm sold its Fab to
Orbit. Following the sale of the Fab, Paradigm and Orbit entered into a Wafer
Manufacturing Agreement whereby Orbit supplied a quantity of wafers to
Paradigm over a specified period of time.
 
  Orbit paid to Paradigm aggregate consideration of $20,000,000 consisting of
$6.7 million in cash, assumption of $7.5 million of indebtedness associated
with and secured by the Fab, and promissory notes in the aggregate principal
amounts of $5.8 million. Paradigm recorded a loss of $4.6 million in the
quarter ended December 31, 1996 as a result of the sale of its wafer
fabrication facility. This charge included the excess of the net book value of
leasehold improvements, wafer fabrication equipment, fabrication work in
process inventory and other assets sold to Orbit over the proceeds received
from Orbit, an accrual for professional fees, a reserve for an adverse
purchase commitment related to the wafer manufacturing agreement and accruals
for other costs. See Note 11 of Notes to Financial Statements.
 
  In connection with the sale of the Fab, substantially all of the 109
employees associated with the Fab were terminated and became employees of
Orbit. No severance payments were made to employees transferred to Orbit.
 
  Paradigm also implemented a reduction in the work force of approximately 35
employees and took a charge of approximately $150,000 in the fourth quarter of
1997 associated with severance payments and other related costs.
 
COMPARISON OF RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 1997 TO
THE YEAR ENDED DECEMBER 31, 1996
 
  Sales. Sales decreased by 46% to $12.4 million in the year ended December
31, 1997, from $23.2 million in the year ended December 31, 1996. Paradigm
experienced a significant downward trend in pricing during 1997 and 1996,
caused by an excess supply relative to demand for certain SRAM products.
Paradigm expects the downward price trend in the industry to continue. The
decrease in unit prices was offset by a higher volume of units shipped in 1997
compared to 1996. Unit shipments increased by 33% from 1996 to 1997.
 
  The SRAM business is highly cyclical and has been subject to significant
downturns at various times. These downturns have been characterized by
diminished product demand, production overcapacity, intense competition and
accelerated erosion of average selling prices.
 
  Gross Profit. Gross profit increased to a profit of $503,000 in the year
ended December 31, 1997, from a loss of $(13.2) million in the year ended
December 31, 1996. As a percentage of sales, gross profit in the year ended
December 31, 1997 was 4%, compared to (57%) for the year ended December 31,
1996. The increase in gross profit resulted primarily from the implementation
of a strict company-wide cost reduction program which enabled Paradigm to
reduce its external wafer fabrication subcontract costs and internal test and
assembly costs. During the year ended December 31, 1997, in response to the
continuing erosion of average selling prices, Paradigm made lower of cost or
market provisions of $650,000. During the year ended December 31, 1996,
Paradigm provided lower of cost or market provisions of $2,475,000 and write-
offs of $3,325,000 related to older generation SRAM products to reflect
reduced product demand and current industry pricing trends.
 
  Research and Development. Research and development expenses decreased by 45%
to $3.4 million in the year ended December 31, 1997, from $6.2 million in the
year ended December 31, 1996. The decrease in
 
                                      104
<PAGE>
 
expenses in 1997 resulted from headcount reductions, the decision in early
1997 to shut down product development associated with the NewLogic acquisition
made in 1996, and a more direct focus on core SRAM products and markets. As a
percent of sales, research and development expenses were approximately 27% in
1997 and 1996.
 
  Selling and Administrative. Selling, general and administrative expenses
decreased by 48% to $4.9 million in the year ended December 31, 1997, from
$9.5 million in the year ended December 31, 1996. The decrease resulted from
headcount reductions and Paradigm's cost reduction program implemented in mid-
1997.
 
  Other Operating Expenses. Paradigm recorded a loss of $4.6 million in the
year ended December 31, 1996 as a result of the sale of its wafer fabrication
facility. This charge included the excess of the net book value of leasehold
improvements, wafer fabrication equipment, fabrication work in process
inventory and other assets sold to Orbit over the proceeds received from
Orbit, an accrual for professional fees incurred to complete the transaction,
a reserve for an adverse purchase commitment related to the wafer
manufacturing agreement and accruals for other estimated costs to be incurred.
 
  In June 1996, Paradigm acquired, through a stock purchase and merger
transaction, NewLogic, a company which developed and manufactured logic
designs with large memory arrays. In exchange for its purchase of the NewLogic
capital stock, Paradigm issued 31,439 shares of Paradigm's common stock, with
a market value of approximately $2,656,000, and approximately $825,000 in
cash. In addition, Paradigm incurred transaction costs of approximately
$237,000. The fair value of NewLogic's tangible net assets at the date of
acquisition was a deficit of $373,000. Approximately $3,841,000 of the
purchase price in excess of the fair market value of the net tangible assets
was allocated to in-process technology which Paradigm wrote off in the quarter
ended June 30, 1996. Approximately $250,000 was allocated to other
intangibles. The unamortized balance of these other intangibles was written
off in connection of the shut-down of NewLogic in early 1997.
 
  Interest Expense. Interest expense decreased to $370,000 in the year ended
December 31, 1997, from $1.1 million in the year ended December 31, 1996. The
decrease reflects the reduced level of debt in 1997 following the repayment of
certain outstanding debt in 1996, and Paradigm's efforts to reduce its
operating expenses and capital equipment spending in 1997.
 
  Other (Income) Expense, Net. For the year ended December 31, 1997, other
expenses, net, mainly consisted of losses on sales of, and write offs of,
equipment. For the year ended December 31, 1996, other income, net, reflected
interest income earned on the remaining portion of net proceeds of Paradigm's
1995 public offering and a gain on the sale of certain fixed assets.
 
  Taxes. Paradigm has a tax year that ends in March. In 1997 and 1996,
Paradigm's effective tax rates were 0% and (3%), respectively. The 1996 tax
benefit reflects the benefit at the statutory rate of the operating losses
reduced by valuation allowances on tax losses not recognized due to the
uncertainty of realizing the benefit of these losses. No net benefit was
recognized in 1997.
 
COMPARISON OF RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 1996 TO
THE YEAR ENDED DECEMBER 31, 1995
 
  Sales. Sales decreased by 55% to $23.2 million in the year ended December
31, 1996 from $51.9 million in the year ended December 31, 1995. Paradigm
experienced a significant downward trend in pricing during 1996 that was
caused by an excess supply relative to demand for certain SRAM devices.
Paradigm expects this downward price trend to continue. In addition, Paradigm
shipped lower volumes of units in 1996 compared to 1995. Unit shipments
declined 48% from 1995 to 1996.
 
  The SRAM business is highly cyclical and has been subject to significant
downturns at various times that have been characterized by diminished product
demand, production overcapacity, and accelerated erosion of average selling
prices.
 
 
                                      105
<PAGE>
 
  Gross Profit. Gross profit decreased from $20.9 million in the year ended
December 31, 1995 to a loss of ($13.2) million in the year ended December 31,
1996 and, as a percentage of sales, from 40% to (57%), respectively. The
decrease in gross profit resulted principally from industry-wide pricing
pressures experienced by Paradigm in 1996 caused by an oversupply in the SRAM
marketplace. These pricing pressures directly impacted profits as average
selling prices for Paradigm's products declined during the year ended December
31, 1996 when compared to 1995. In addition, during 1996 Paradigm provided
lower of cost or market provisions of $2,475,000 and write-offs of $3,325,000
related to older generation SRAM products to reflect reduced product demand
and current industry pricing trends.
 
  Paradigm's conversion of its internal fabrication facility from five-inch to
six-inch wafer manufacturing was completed in 1996 and caused temporary
declines in output and reductions in yield. This facility was sold in November
1996 to provide Paradigm increased flexibility and lower fixed costs.
 
  Research and Development. Research and development expenses increased by 35%
to $6.2 million in the year ended December 31, 1996, from $4.6 million in the
year ended December 31, 1995. As a percentage of sales, research and
development expenses have increased from 9% in 1995 to 27% in 1996. Increased
expenses result primarily from increased headcount required to support
Paradigm's co-development activities with Atmel, new product development and
other development activities. In addition, research and development expenses
increased in 1996 as a result of Paradigm's acquisition of NewLogic in June
1996. Research and development expenses, as a percentage of revenue, have also
increased as a result of the decline in revenue in 1996 compared to 1995.
 
  In June 1996, Paradigm acquired NewLogic with the strategy to expand
Paradigm's product line beyond SRAMs. In early 1997, Paradigm believed that it
was in Paradigm's best interest to shut down the NewLogic operation and focus
on Paradigm's core SRAM products and markets.
 
  Selling, General and Administrative. Selling, general and administrative
expenses increased by 17% to $9.5 million in the year ended December 31, 1996
from $8.1 million in the year ended December 31, 1995. Selling, general and
administrative expenses include approximately $1.4 million in bad debt expense
in 1996 compared to $.1 million in 1995 due to financial problems at several
of Paradigm's customers.
 
  Interest Expense. Interest expense decreased to $1.1 million in the year
ended December 31, 1996, from $1.4 million in the year ended December 31,
1995. This decrease in interest expense reflects repayment of certain
outstanding debt by Paradigm from the proceeds of its initial public offering,
which was subsequently replaced in 1996 with new debt at lower interest rates.
See "--Liquidity and Capital Resources."
 
  Other Income, Net. For the years ended December 31, 1996 and December 31,
1995, other income, net, reflects interest income earned on the investment of
the net proceeds to Paradigm from its initial public offering. In addition,
other income in 1996 includes a gain on the sale of fixed assets.
 
  Taxes. Paradigm has a tax year that ends in March. Paradigm's tax provision
for the resultant nine month tax period ended December 31, 1995 reflected the
statutory rate reduced by net operating loss benefits and other credits. The
amount of net operating loss Paradigm may utilize in any year is limited due
to the change of ownership which occurred as a result of the Paradigm
Reorganization. Paradigm incurred a net loss for its tax year ended March 31,
1995 and thus no provision has been reflected in the quarters in the period
from the reorganization through March 31, 1995. In 1996 Paradigm's effective
tax rate was (3%) which reflects the benefit of the statutory rate of the
operating loss reduced by tax losses not recognized due to the uncertainty of
realizing the benefit of these losses.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  During the year ended December 31, 1997, Paradigm's operating, investing and
financing activities used $126,000 of cash, compared to using cash of $3.4
million during the year ended December 31, 1996, and generating cash of $3.9
million during the year ended December 31, 1995.
 
                                      106
<PAGE>
 
  During the year ended December 31, 1997, $5.3 million of cash was used in
operations, compared to the use of $15.6 million of cash during the year ended
December 31, 1996 and $8.1 million in cash generated from operations in 1995.
The $5.3 million of cash used by operations during the year ended December 31,
1997, was mainly attributed to the net loss for the year of $8.9 million and a
reduction of accounts payable and other liabilities of $4.2 million, offset by
non-cash charges of $1.7 million for depreciation and amortization, a loss of
$1.7 million on the sale of and write off of fixed assets, a reduction in
other assets of $4.3 million, including $3.1 million related to the sale of
the wafer fabrication facility in 1996 and proceeds from a refund of Federal
income taxes of $1.2 million. The $15.6 million of cash used by operations
during the year ended December 31, 1996, was mainly attributable to the net
loss for the year of $36.4 million and a reduction in other liabilities of
$3.7 million, offset by non-cash charges of $5.7 million for depreciation and
amortization, the write-off of in-process technology associated with the New
Logic acquisition of $3.8 million, a loss of $4.6 million on the sale of
Paradigm's wafer fabrication facility and a reduction of $6.1 million in
accounts receivable that reflects the lower sales volume in 1996 compared to
1995. The $8.1 million of cash generated from operations during the year ended
December 31, 1995, was mainly attributable to the net profit for the year of
$5.3 million and an increase in accounts payable of $3.5 million as Paradigm
re-established its relationship with suppliers subsequent to the Paradigm
Reorganization in 1994, and other liabilities (primarily income taxes payable)
of $3.0 million. In addition, an increase of $5.7 million in accounts
receivable was offset by non-cash charges of $5.1 million for depreciation and
amortization.
 
  Investing activities generated $506,000 in 1997, compared to $9.7 million
generated in 1996, and $30.8 million used in 1995. Funds generated in 1997 are
primarily attributable to proceeds from the sale of fixed assets. In 1996, the
sale of $19.9 million of short-term investments funded Paradigm's conversion
of its wafer fabrication facility to 6" wafers ($14 million). In 1995, $18.7
million of short-term investments were purchased from the net proceeds of
Paradigm's initial public offering in June of 1995. In addition, $13.7 million
was used to convert the wafer fabrication facility to 6" wafers and expand
Paradigm's test floor.
 
  Cash generated from financing activities amounted to $4.6 million during the
year ended December 31, 1997, and resulted primarily from the issuance of
Paradigm Series A, B, and C Preferred Stock. Cash generated from financing
activities in the amount of $2.5 million in 1996 resulted primarily from an
increase of $2.0 million in borrowings from Paradigm's line of credit and the
issuance of $11.3 million of notes payable, offset by $11.6 million of
payments made on notes payable. Cash provided from financing activities in
1995 amounted to $26.8 million and is mainly attributable to Paradigm's
initial public offering on June 28, 1995, which provided net proceeds to
Paradigm of approximately $28.3 million, and issuance of notes payable ($9.3
million), partially offset by payments on capital leases ($7.7 million) and
the decrease in a line of credit ($4.6 million). In addition, in April 1995
Paradigm sold a total of 42,500 shares of Common Stock to Atmel for an equity
investment of $3.4 million.
 
  In November 1996, Paradigm replaced an existing line of credit with a new
line of credit from Greyrock Business Credit with a borrowing limit of $6
million of which $513,000 was available at December 31, 1996. Borrowings under
this line of credit were limited to up to 80% of eligible receivables and
interest was at the greater of LIBOR plus 5.25% or 9%. At December 31, 1996,
the outstanding balance under this line of credit was $2.0 million.
 
  In October 1997, Paradigm renewed its line of credit with Greyrock Business
Credit, with certain modifications. Borrowing was limited to the lesser of $5
million or the sum of (a) 80% of the amount of eligible receivables owing from
original equipment manufacturers; plus (b) 50% of the amount of eligible
receivables owing from distributors. The interest rate remained unchanged from
the November 1996 agreement. The line of credit is subject to renewal again in
October 1998, unless prior notice is given by either party to terminate the
agreement. The line of credit is secured by Paradigm's trade receivables,
inventory, equipment and general intangibles. Paradigm cannot incur additional
debt or pledge assets without the prior approval of Greyrock Business Credit.
At December 31, 1997, the outstanding balance under the line of credit was
$1.7 million.

  In November 1996, Paradigm sold its wafer fabrication operations to Orbit.
Orbit assumed $7.5 million of outstanding borrowings with the CIT Group that
were secured by wafer fabrication equipment that was purchased. Paradigm used
approximately $2.2 million of the cash proceeds from the sale of the wafer
fabrication facility to pay off existing borrowings under lines of credit.
 
  Paradigm's recent operations have consumed substantial amounts of cash.
During 1997, Paradigm completed the private placement of Paradigm Series A
Preferred Stock, Series B Preferred Stock, and Series C Preferred Stock for
aggregate net proceeds of approximately $4,673,000. (See Note 7 of Notes to
Financial Statements.) Paradigm believes that it will require additional cash
infusion from similar private placements of equity or other sources of
liquidity, such as asset sales and equipment financing to meet Paradigm's
projected working capital and other cash requirements. The sale of additional
equity or other securities could result in additional dilution to Paradigm's
stockholders. There can be no assurance that such additional financing, if
required, can be obtained on acceptable terms, if at all.
 
  On March 6, 1998, Paradigm entered into a definitive merger agreement
providing for the acquisition of all of the outstanding capital stock of IXYS
in exchange for Paradigm Common Stock. Consummation of the Merger requires the
approval of Paradigm's and IXYS' stockholders and various regulatory
approvals. If approved, the transaction is anticipated to be accounted for as
a purchase of Paradigm by IXYS for financial reporting purposes.
 
RESULTS OF OPERATIONS--THREE MONTHS ENDED MARCH 29, 1998 COMPARED TO MARCH 31,
1997
 
 Sales
 
  Paradigm's net sales of $1.9 million for the three month period ended March
29, 1998 decreased 46% from sales of $3.6 million in corresponding period in
fiscal year 1997. Paradigm has continued to experience a significant downward
trend in pricing that began in late 1995 in addition to lower volumes of units
shipped when compared to 1997. The reduced selling prices of Paradigm's
products and reduced unit shipments are both principally a result of the
significant excess supply of SRAM devices relative to demand that the SRAM
market has been experiencing since late 1995.
 
  The SRAM business is highly cyclical and has been subject to significant
downturns at various times that have been characterized by diminished product
demand, production overcapacity, and accelerated erosion of average selling
prices. During the latter part of 1995, continuing into 1996, 1997 and 1998,
the market for SRAM devices experienced an excess supply relative to demand
which resulted in a significant downward trend in prices. Paradigm could
continue to experience a downward trend in pricing which could adversely
affect Paradigm's operating results.
 
 Gross Profit
 
  Gross profit of $144,000 for the three month period ended March 29, 1998
decreased 44% from gross profit of $258,000 for the comparable period in
fiscal 1997. Paradigm continues to experience industry-wide pricing pressures
caused by an oversupply in the worldwide SRAM marketplace. These pricing
pressures directly impacted profits as average selling prices of Paradigm's
products declined during the quarter ended March 29, 1998 when compared to the
comparable periods in 1997.
 
  Paradigm's future needs for wafers will need to be supplied by third
parties. Constraints or delays in the supply of Paradigm's products, whether
because of capacity constraints, unexpected disruptions at the current or
future foundries or assembly houses, delays in obtaining additional production
at the existing foundry or in obtaining production from new foundries,
shortages of raw materials, or other reasons, could result in the loss of
customers and other material adverse effects on Paradigm's operating results,
including effects that may result should Paradigm be forced to purchase
products from higher cost foundries or pay expediting charges to obtain
additional supply.

<PAGE>
 
 Research and Development
 
  Research and development expenses decreased to $304,000 in the three month
period ended March 29, 1998 from $1.2 million in the corresponding period in
fiscal 1997. As a percentage of revenues, these expenses have decreased to 16%
in the three month period ended March 29, 1998 from 33% in the corresponding
period of 1997. This decrease is due to the shutdown of NewLogic and other
cost cutting measures implemented by Paradigm.
 
 Selling, General and Administrative
 
  Selling, general and administrative expenses were $744,000 in the three
month period ended March 29, 1998 compared to $1.6 million in the comparable
period in 1997. This decline is attributable to the cost cutting measures
implemented by Paradigm.
 
 Interest Expense, Net
 
  Interest expense, net, of $71,000, for the three month period ended March
29, 1998 compares to $42,000 in the corresponding period in fiscal 1997. This
increase in net interest expense for the three month period in 1998 reflects
higher average outstanding debit balances.
 
 Taxes
 
  Paradigm provides for income taxes during interim reporting periods based
upon an estimated annual tax rate. During the three month period ended March
29, 1998, Paradigm recorded a loss for tax purposes. Paradigm has net
operating loss carryforwards to offset future regular and alternative minimum
taxable income. Paradigm's net operating loss carryforwards expire through
2011, if not utilized.
 
LIQUIDITY AND CAPITAL RESOURCES--MARCH 29, 1998
 
  Paradigm's operating, investing and financing activities used $243,000 in
cash in the three month period ended March 29, 1998 compared to generating
$768,000 of cash in the comparable period in 1997. Operating activities
provided $215,000 in cash in 1998 compared to a use of $736,000 of cash in
1997. This increase of $951,000 is primarily due to a smaller net loss as a
result of reductions in operating expenses and a decrease in accounts
receivable balances.
 
  There were no investing activities in the 1998 period compared to fixed
asset purchases of $261,000 in the 1997 period. This is due to the fact that
Paradigm has successfully transferred its manufacturing and testing activities
to outside foundries and sub contractors.
 
  Financing activities used $458,000 in the 1998 period compared to providing
$1.8 million in the 1997 period. Borrowing under Paradigm's line of credit
decreased by $680,000 in the 1998 period compared to the 1997 period. This is
due to lower revenue in the 1998 period compared to the 1997 period and a
change in the terms of the line of credit agreement with Greyrock Business
Credit.
 
  In November 1996, Paradigm replaced an existing line of credit with a line
of credit from Greyrock Business Credit with a borrowing limit of $6,000,000.
Borrowings under this new line of credit with Greyrock Business Credit were
limited to up to 80% of eligible receivables and interest was at the greater
of LIBOR plus 5.25% or 9%.
 
  In October 1997, Paradigm renewed its line of credit with Greyrock Business
Credit with certain modifications. Borrowing was limited to the lesser of $5
million or the sum of (a) 80% of the amount of eligible receivables owing from
original equipment manufacturers; plus (b) 70% of the amount of eligible
receivables owing from distributors. The interest rate remained unchanged from
the November 1996 agreement.
 
 
                                      109
<PAGE>
 
  In January 1998, Paradigm amended its line of credit with Greyrock Business
credit to limit borrowing to the lesser of $5 million or the sum of (a) 80% of
the amount of eligible receivables owing from original equipment
manufacturers; plus (b) 50% of the amount of eligible receivables owing from
distributors. The interest rate remained unchanged from the November 1996
agreement. At March 29, 1998, the outstanding balance under this line of
credit was approximately $1.3 million. The line of credit is secured by
Paradigm's trade receivables, inventory, equipment and general intangibles.
 
  Paradigm's recent operations have consumed substantial amounts of cash.
During 1997, Paradigm completed the private placement of Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock for aggregate net
proceeds of approximately $4,673,000. Paradigm believes that it will require
additional cash infusion from similar private placements of equity or other
sources of liquidity, such as asset sales and equipment financing to meet
Paradigm's projected working capital and other cash requirements. The sale of
additional equity or other securities could result in additional dilution to
Paradigm's stockholders. There can be assurance that such additional
financing, if required, can be obtained on acceptable terms, if at all.
 
  As a result of these circumstances, Paradigm's independent accountants'
opinion on Paradigm's December 31, 1997 financial statements includes an
explanatory paragraph indicating that these matters raise a substantial doubt
about Paradigm's ability to continue as a going concern.
 
  On March 6, 1998, Paradigm entered into a definitive merger agreement
providing for the acquisition of all of the outstanding capital stock of IXYS
Corporation ("IXYS") in exchange for Common Stock of Paradigm. The exchange
ratio in the Merger for the IXYS equity securities will be the greater of two
ratios. The first ratio provides that upon the Merger the holders of equity
securities of IXYS hold 95% of the fully diluted capitalization of the
combined company and that the holders of equity securities of Paradigm will
hold 5% of the fully diluted capitalization of the combined company. (As used
herein, fully diluted capitalization means the sum of the number of shares of
common stock outstanding and issuable upon exercise or conversion of all
outstanding preferred stock, warrants, options and other rights.) The second
ratio provides that the value associated with the fully diluted capitalization
of IXYS, at the time of the consummation of the Merger, be at least $150
million, based upon an average of the closing prices of Paradigm's Common
Stock prior to Paradigm's stockholders meeting. Consummation of the merger
requires the approval of Paradigm's and IXYS' stockholders and various
regulatory agency approvals. If approved, the transaction is anticipated to be
accounted for as a purchase of Paradigm by IXYS for financial reporting
purposes.
 
LITIGATION--SEE "RISK FACTORS."
 
FACTORS AFFECTING FUTURE RESULTS
 
  Paradigm's operating results have been, and in the future may be, subject to
fluctuations due to a wide variety of factors, including the timing of new
product and process technology, announcements and introductions by Paradigm or
its competitors, competitive pricing pressures, fluctuations in manufacturing
yields, changes in the mix of products sold, availability and costs of raw
materials, industry-wide shifts in the supply of and demand for SRAMs,
intellectual property disputes and litigation, and other risks, including
risks disclosed in this Joint Proxy Statement/Prospectus and other filings
with the Commission. There can be no assurance that Paradigm will be able to
effectively compete in the future against existing or potential competitors or
that Paradigm's operating results or financial condition will not continue to
be adversely affected by increased price competition.
 
  The semiconductor industry is highly cyclical and has been subject to
significant down-turns at various times and by diminished product demand,
production overcapacity and accelerated erosion of average selling prices.
During 1996 and 1997, Paradigm experienced, and expects it will continue to
experience, significant decreases in selling prices for its SRAM products.
Such price decreases could have a material adverse effect on Paradigm's
operating results.

RECENT ACCOUNTING PRONOUNCEMENTS
 
  In June 1997, the FASB issued SFAS 130, "Reporting Comprehensive Income."
SFAS 130 establishes standards for reporting comprehensive income and its
components in a financial statement. Comprehensive income as defined includes
all changes in equity (net assets) during a period from non-owner sources.
Examples of items to be included in comprehensive income, which are excluded
from net income, include foreign currency translation adjustment and
unrealized gain/loss on available for sale securities. The disclosure
prescribed by SFAS must be made beginning with the first quarter of fiscal
1998 and will have no impact on Paradigm's financial position or results of
operations.
 
  In June 1997, the FASB issued SFAS 131, "Disclosure about Segments of an
Enterprise and Related Information." This statement establishes standards for
the way companies report information about operating segments in annual
financial statements. It also establishes standards for related disclosures
about products and services, geographic areas, and major customers. The
disclosures prescribed by SFAS 131 are effective in fiscal 1998.

                                 IXYS BUSINESS
 
GENERAL
 
  IXYS designs, develops and markets power semiconductors used primarily in
controlling energy in motor drives, power conversion (including
uninterruptible power supplies ("UPS") and switch mode power supplies
("SMPS")) and medical electronics. IXYS' power semiconductors convert
electricity at relatively high voltage and current levels to create efficient
power as required by a specific application. IXYS' target market includes
segments of the power semiconductor market that require medium to high power
semiconductors, with a particular emphasis on higher power semiconductors,
which IXYS considers to be those capable of processing greater than 500 watts
of power. IXYS offers a broad line of power semiconductors, including power
MOSFETs, insulated gate bipolar transistors ("IGBTs"), thyristors (silicon
controlled rectifiers or "SCRs") and rectifiers, including fast recovery
epitaxial diodes ("FREDs"). A glossary of relevant technical terms is set
forth at the end of this section of the Joint Proxy Statement/Prospectus.
 
  IXYS' major customers include Still GmbH, Rockwell International
Corporation, Emerson Electric Company, Eurotherm Ltd. (U.K.), Medtronics Inc.,
ABB, Guidant Corporation, General Signal, Alpha Technology and Siemens AG.
 
  There has been no public market for the IXYS Capital Stock. IXYS has not
declared or paid any cash dividends on any series of its capital stock during
any period for which information is provided in this Joint Proxy
Statement/Prospectus. Following the Merger, the Combined Company does not
intend to declare or pay any cash dividends in the foreseeable future.
 
BACKGROUND
 
  As the world enters the 21st century, demand for electricity is forecasted
to increase faster than demand for other forms of energy. Electrical energy is
demanded worldwide at an increasing rate due to (i) the introduction of new
technologies that require electricity, including computers, telecommunications
equipment, industrial machinery and automation and transportation, (ii) the
increased use of electrical processes in industry and transportation, (iii)
the increasing energy demands of electrical products requiring greater power
than more traditional electrical products because of the additional features
provided by these products and (iv) the economic development of emerging third
world countries, including China which industry sources report is expected to
more than double its electrical consumption from 1990 to 2010. As a result of
these and other factors, the U.S. Department of Energy reports that worldwide
electrical power consumption is expected to increase from approximately 11.4
trillion kilowatt hours in 1995 to approximately 20 trillion kilowatt hours in
2015.
 
  The increasing demand for electrical energy, government regulation requiring
energy efficiency and social and environmental concerns have caused an
increased demand for energy efficiency. Government regulations are also
imposing efficiency requirements on products and equipment. For example, the
European Community has adopted the IEC-555 standard that regulates the
efficiency of certain power supplies and has effectively required SMPS
manufacturers to incorporate power factor correction ("PFC") circuits, which
require power semiconductors, in their higher power supplies. Finally,
environmental concerns related to pollution and the depletion of natural
resources further support the demand for energy efficiency.
 
  In addition to the demand for energy efficiency, electrical products in all
markets are becoming increasingly sophisticated, offering "intelligence"
through the use of microprocessors and additional components. The integration
of microprocessors into such products as home appliances, office equipment and
industrial controls will continue as products gain "intelligence." As a result
of the introduction of microprocessors and integrated circuits, products
require increasingly sophisticated power supplies that are capable of
providing precisely regulated power (free of spikes and surges) as required by
a specific application. This must be done without adding to the existing size
of the product or equipment, thereby putting pressure on power supply
designers to improve efficiency (i.e., increase the power output of power
supplies without increasing their size). Additionally,
 
                                      112
<PAGE>
 
uninterruptible power operation is a requirement for such applications as
intranet and internet servers, telecommunications, hospitals and financial
institution equipment.
 
ROLE OF POWER SEMICONDUCTORS
 
  Power semiconductors address the demand for energy efficiency and are
essential for providing the precisely regulated power required by
sophisticated electrical products and equipment. Power semiconductors process
and control the electrical energy generated by electrical utilities to provide
efficient power systems and precisely regulated power as required by a
specific application. Most equipment needs to process the voltage level and
frequency delivered by the utility to derive the required power at specific
voltage, current and frequency levels, and power semiconductors help provide
this function. Power semiconductors (i) convert or "rectify" alternating
current ("AC") power delivered by electrical utilities to direct current
("DC") power which is useable by most equipment; (ii) convert DC power at a
certain voltage level to DC power at a different voltage level to meet the
specific voltage requirement for an application; (iii) invert DC power to high
frequency AC power to permit the processing of power with substantially
smaller electronic components and (iv) rectify high frequency AC power from
SMPS to meet the specific DC voltage required by an application. Energy
efficiency is obtained in part through efficient power control designs. As a
result, the power semiconductors that perform the task of controlling and
regulating the power in equipment are required to perform with a high degree
of efficiency, with minimal wasting of energy.
 
POWER SEMICONDUCTOR APPLICATIONS
 
  Power semiconductors are used in controlling energy in motor drives and
power conversion systems, including SMPS and UPS. Motor drive controls
regulate the voltage, current and frequency of power to a motor to control the
speed, torque, position, efficiency and other features of a motor. A SMPS
efficiently converts power as provided by electrical utilities to meet the
specific voltage requirements of an application. A UPS provides a short term
backup of electricity to the power supply in the case of an interruption of
power from the primary source of electricity.
 
  Power semiconductors can be classified based upon the amount of power that
they are capable of handling. Generally, IXYS views lower power semiconductors
as those capable of handling less than 500 watts of power. lower power
semiconductors are used in small motor drives, UPS and SMPS for personal
computers, telephones, automotive electronics, stereo equipment and battery
operated tools and equipment.
 
  IXYS views higher power semiconductors as those capable of handling power in
excess of 500 watts. Industrial and commercial motor drive control
applications for higher power semiconductors include robotics, machine tools,
pumps, heating, ventilation and air conditioning systems ("HVAC"), appliances
and transportation systems. Applications for higher power semiconductors in
SMPS include mainframe and workstation computers, instrumentation and
telecommunications. Applications for higher power semiconductors in UPS
include power back-up for hospitals, financial institutions, mainframes,
workstations, local area networks, communications systems and industrial
equipment.
 
POWER SEMICONDUCTOR MARKET
 
  The power semiconductor market consists of power transistors (including
IGBTs and power MOSFETs), rectifiers and thyristors. According to World
Semiconductor Trade Statistics ("WSTS"), the worldwide market for power
semiconductors in 1997 was $8.2 billion and is projected to increase to $9.1
billion in 1998. IXYS believes that growth in the power semiconductor market
is driven in part by the need for an increased number of power semiconductors
for a given application as power control requirements become more
sophisticated, the increased number of end-user applications for power
semiconductors and the resulting higher dollar value of power semiconductors
included in products and equipment.
 
  WSTS indicate that worldwide sales of IGBTs, substantially all of which are
higher power semiconductors, and power MOSFETs, a substantial portion of which
are higher power semiconductors, were projected to grow
 
                                      113
<PAGE>
 
from approximately $2.6 billion in 1995 to $2.8 billion in 1997 to $3.4
billion in 1998. Sales of power MOSFETs and IGBTs are experiencing stronger
growth than other segments of the power semiconductor market as these products
are used to replace traditional bipolar transistors, such as rectifiers and
thyristors. In addition to the relatively fast rate of growth for power
MOSFETs and IGBTs, IXYS believes that FREDs will grow at higher growth rates
than standard diodes since they are required in the same faster switching
circuits in which power MOSFETs and IGBTs are included. In fact, almost all
IGBTs included in motor drives require a FRED, and SMPS with PFCs require a
FRED as a boost diode or as an output rectifier.
 
IXYS APPROACH
 
  Since its inception, IXYS has focused on the higher power segment of the
power semiconductor market and has focused its product development and
marketing efforts on the specific needs of customers in this segment of the
market. In contrast to most other competitors in the power semiconductor
market, including large international companies, IXYS is focused almost
exclusively on the design, manufacture and marketing of power semiconductors,
with a particular emphasis on higher power semiconductors. Approximately 90%
of the IXYS' sales in fiscal 1998 were of higher power products. Through its
broad product line and range of packaging options, its ability to mobilize its
focused organization (which includes a wide range of technical capabilities)
quickly to bring new products to the market and its ability to collaborate
with its customers in the development of products designed to meet their
needs, IXYS has become a leader in the higher power semiconductor market.
 
IXYS STRATEGY
 
  IXYS intends to build a leadership position within its targeted higher power
segment of the power semiconductor market by pursuing the following business
strategies:
 
 Maintain Technological Leadership Within Higher Power Market
 
  IXYS intends to maintain its technological leadership with respect to higher
power semiconductors by focusing its scientific expertise on the development
of these semiconductors. This expertise encompasses a wide range of technical
capabilities, including physics, mechanical engineering, chemistry, circuit
design and material science capabilities. IXYS also intends to use its
expertise with respect to semiconductor packaging and assembly to develop
technologically advanced packaging of its higher power semiconductors.
 
 Target Rapid Growth Applications Within the Higher Power Market
 
  IXYS' strategy is to target markets by evaluating the growth of those
markets and IXYS' ability to establish a leadership position in them based
upon its technological capabilities, the level of competition in the markets
and the overall performance of the products offered by competitors. For
example, IXYS has targeted the market for power supplies used in servers,
which IXYS believes represents an attractive market, and has focused its
efforts on providing power semiconductors for this application. IXYS intends
to pursue this element of its strategy through the development of new
technology and products for high growth markets and the packaging of its
existing technology into products tailored to new high growth applications.
 
 Offer Broad Range of Higher Power Products
 
  IXYS' product line is targeted at the higher power segment of the power
semiconductor market across a broad range of functionality and price. IXYS
offers a comprehensive range of power semiconductors that allows it to provide
an appropriate solution to its customers' power semiconductor needs from its
range of standard products. IXYS' product line allows its customers to
purchase a substantial portion of their power semiconductor needs from a
single supplier. IXYS intends to continue to offer a wide array of products by
developing additional products that offer improvements over current products
or address new applications.
 
 
                                      114
<PAGE>
 
 Promote Product Development Collaborations
 
  IXYS seeks to enter into collaborative arrangements with leaders in
attractive end-user markets in order to optimize IXYS products for use by
these customers in their products. IXYS' strategy is to leverage these
collaborative arrangements into sales to other manufacturers of end-user
products in these markets. For example, in 1988 IXYS targeted the
defibrillator market and continues to be the leading supplier of IGBTs for
this application. IXYS has leveraged its relationships with the two
implantable defibrillator market leaders to include other IXYS products,
including power MOSFETs and thyristors, in their products. IXYS believes that
its ability to provide technical assistance with respect to the design of
hardware and software systems by its customers encourages the incorporation of
its devices in products manufactured by its customers. IXYS believes that it
has gained a reputation for strong product development collaborations, which
has contributed to the inclusion of its semiconductors in products designed by
its customers, and intends to expand its efforts in this area.
 
 Maintain Balance Between Internal and External Manufacturing
 
  IXYS intends to take advantage of its combination of in-house wafer
fabrication facilities and its foundry relationships to maximize its
manufacturing efficiency and flexibility. IXYS believes that its in-house
manufacturing capabilities enable it to lower its manufacturing cost with
respect to certain products, bring products to the market more quickly than
would be possible if IXYS were required to rely exclusively on outside
foundries, retain certain proprietary aspects of its process technology and
more quickly introduce new process innovations. In particular, IXYS continues
to fabricate its 1,600 volt and greater power MOS devices at its Lampertheim
facility to better protect its process technologies with respect to the
fabrication of these products. IXYS also believes that its in-house wafer
fabrication facilities provide it with a significant competitive advantage
because the fabrication facilities permit close collaborations between design
and process engineers in the development of new products. In addition to
maintaining its own fabrication facilities, IXYS establishes alliances with
selected foundries for wafer fabrication. This approach allows IXYS to reduce
substantial capital spending and manufacturing overhead expenses, obtain
competitive pricing and technologies and optimize production schedules while
retaining the flexibility to shift the production of its products to a
different or additional foundries for cost or performance reasons. IXYS'
product designs enable the production of its devices at multiple foundries
using well-established and cost-effective processes. IXYS intends to continue
to strategically expand its in-house manufacturing capabilities while
continuing its significant reliance on outside foundries which permit IXYS to
reduce its exposure to the large capital expenditures required for increasing
in-house manufacturing capacity.
 
PRODUCTS AND APPLICATIONS
 
  IXYS' products perform any of the four functions performed by power
semiconductors:
 
  .  Conversion or "rectification" of power delivered by electrical utilities
     to DC power which is useable by most equipment ("input rectification")
 
  .  Conversion of DC power at a certain voltage level to DC power at a
     different voltage level to meet the specific voltage requirement for an
     application
 
  .  Inversion of DC power to high frequency AC power to permit the
     processing of power with substantially smaller electronic components
 
  .  Rectification of high frequency AC power from SMPS to meet the specific
     DC voltage required by an application ("output rectification")
 
  IXYS designs, develops and markets power semiconductors used primarily in
controlling energy in motor drives, power conversion (including UPS and SMPS)
and medical devices, sales of which represented 39%, 38% and 5% of IXYS'
revenues in fiscal 1998, respectively.
 
  An SMPS converts AC power to regulated DC power. AC power is converted to
high voltage DC power through input rectifiers and is then switched to a very
high frequency AC. The AC power is then stepped down to a different voltage
and converted through output rectification to produce the required DC power.
 
                                      115
<PAGE>
 
  A UPS continues to supply AC power to electronic equipment in the event of
an electrical utility power failure. A UPS consists of an SMPS, battery
chargers, a semiconductor transfer switch to activate the UPS and an inverter
to invert DC battery power to AC power.
 
  IXYS' principal products are power MOSFETs, IGBTs, FREDs, thyristors and
other rectifiers. During fiscal 1998, power MOS products (including MOSFETs
and IGBTs), rectifiers, FREDs and thyristors constituted approximately 44%,
15%, 14% and 23% of IXYS' revenues, respectively. IXYS also markets DCB
substrates for use with power semiconductors and integrated circuits. IXYS'
power semiconductors are sold separately and are also packaged in high power
modules that frequently consist of multiple semiconductor die. IXYS believes
that the packaging of its modules constitutes an important element of IXYS'
products, as packaging determines how much power can be controlled and the
reliability of the module.
 
  The following table summarizes the primary categories of uses for power
semiconductors, the IXYS products used in each category, the end-user
applications served by these products and representative customers of IXYS for
each application.

 Power MOS Transistors
 
  Power MOS transistors offer significant benefits over traditional bipolar
transistors. Power MOS transistors operate at much greater switching speed,
which allows the design of smaller and less costly end products, due primarily
to the smaller and less expensive additional peripheral components required at
higher switching frequencies. Power MOS transistors are activated by voltage
rather than current (compared to bipolar transistors), so they require less
external circuitry to operate, making them more compatible with IC controls.
They also offer more reliable long-term performance and are more rugged,
permitting them to better withstand adverse operating conditions. In addition,
power MOSFETs and IGBTs compare favorably to bipolar power transistors on a
system price/performance basis.
 
  Power MOSFETs. A power MOSFET (metal oxide silicon field effect transistor)
is a switch controlled by voltage at its gate. Power MOSFETs are used in
combination with passive components to vary the amperage and frequency of
electricity by switching on and off at high frequency.
 
 
                                      116
<PAGE>
 
  IXYS' power MOSFETs are focused on higher voltage applications (ranging from
60 to 1,100 volts) and have on-state resistance among the lowest available for
a given die size and voltage. Lower on-state resistance results in increased
efficiency of a power semiconductor device. IXYS believes that as the power
requirements of workstations, servers and other computers increase as the
result of larger and more powerful microprocessors, disk drives and CD/ROMs,
the designers of power supplies will increasingly demand higher power MOSFETs,
particularly to address the greater power requirements of the equipment
without increasing the physical size of the power supply incorporated into the
equipment.
 
  Power MOSFETs have improved the volumetric efficiency of SMPS by allowing
faster switching frequencies (in some cases into the megahertz range),
dramatically reducing the size of associated components such as power
transformers and capacitors. IXYS' power MOSFETs are used primarily in SMPS
and UPS. The prices of IXYS' power MOSFETs vary depending on the quantity
ordered and the packaging of the semiconductors and generally range for
moderate quantities from $5 to $150.
 
  IGBTs. IGBTs (insulated gate bipolar transistors) also are used as switches.
IGBTs have achieved many of the advantages of power MOSFETs and of traditional
bipolar technology by combining the voltage controlled switching features of
power MOSFETs with the superior conductivity and energy efficiency of bipolar
transistors. IGBTs serve the same functions as power MOSFETs, but have
different features, which make their use preferable in certain applications.
For a given semiconductor die size, IGBTs can operate at higher currents and
voltages, making them a more cost effective device compared to power MOSFETs
for high energy applications. The principal tradeoff of IGBTs compared to
power MOSFETs is the switching speed of IGBTs, which is slower than that of
power MOSFETs. IGBTs are seldom used in applications where very fast switching
is required, including SMPS operating at speeds over 150 kilohertz.
 
  An IGBT is the most cost-effective technology used in AC variable speed
motor drives due to its ability to efficiently switch higher power. IGBTs
allow drives to operate at faster frequencies, thereby reducing system cost,
simplifying drive electronics, increasing efficiency and reducing noise. IXYS'
IGBTs are used principally in AC motor drives and defibrillators. The prices
of IXYS' IGBTs vary depending on the quantity ordered and the packaging of the
semiconductors and generally range for moderate quantities from $1 to $120.
 
 Bipolar Products
 
  Rectifiers. Rectifiers convert AC power to DC power and are used primarily
in input and output rectification and inverters. IXYS' rectifiers are used in
DC and AC motor drives, power supplies, lighting and heating controls and
welding. The prices of IXYS' rectifiers vary depending on the quantity ordered
and the packaging of the semiconductors and generally range for moderate
quantities from $1 to $120.
 
  A newer subset of IXYS' rectifier product group is a very fast switching
device known as a FRED (fast recovery epitaxial diode). FREDs limit spikes in
voltage across the power switch to reduce power dissipation and
electromagnetic interference. Because most IGBTs require a FRED to address its
output, FRED sales are expected to move in concert with IGBTs. IXYS' FREDs are
used principally in AC motor drives and power supplies. The prices of IXYS'
FREDs vary depending on the quantity ordered and the packaging of the
semiconductors and generally range for moderate quantities from $0.50 to $55.
 
  Thyristors. Thyristors are switches that can be turned on by a controlled
signal and are turned off only when the output current is reduced to zero,
which occurs in the flow of AC power. Thyristors are preferred over power
MOSFETs and IGBTs in high-voltage, low-frequency AC applications because their
on-state resistance is lower than the on-state resistance of power MOSFETs and
IGBTs. Thyristors also represent the most cost-effective solution in many AC
motor control and amplifier applications.
 
  IXYS' thyristors are used in motor drives, power supplies, lighting and
heating controls and welding. The prices of IXYS' thyristors vary depending on
the quantity ordered and the packaging of the semiconductors and generally
range for moderate quantities from $1 to $250.
 
                                      117

 Other Products
 
  IXYS markets its patented DCB (direct copper bond) substrates to a variety
of customers, including those in the power semiconductor industry, and uses
DCB in the manufacturing of its modules. DCB technology cost-effectively
provides excellent thermal transfer while maintaining high electrical
isolation. It addresses thermal fatigue and die cracking problems encountered
by manufacturers of power semiconductor modules utilizing traditional copper
base plates. The prices of IXYS' DCB products vary and generally range for
moderate quantities from $1.00 to $5.50.
 
  IXYS also markets integrated circuits that have applications associated with
power semiconductors, such as high voltage current regulators, motion
controllers, digital pulse width modulators and power MOSFET/IGBT drivers.
 
SALES AND MARKETING
 
  IXYS sells its products by means of a worldwide selling organization that
includes direct sales personnel, independent representatives and distributors
managed through IXYS' California and Germany offices. IXYS employs 21 people
in its sales and marketing efforts, including 5 in marketing, 7 in sales and 9
in customer support and service. IXYS currently uses 15 independent sales
representative organizations and 7 distributors in North America. IXYS
currently uses 7 independent sales representative organizations and 42
distributors and stocking representatives in the rest of the world. In fiscal
1998, net revenues derived from North American and international sales
represented approximately 37% and 63%, respectively, of IXYS' net revenues,
with approximately 53% of IXYS' net revenues derived from sales to Europe and
the Middle East and 10% of IXYS' net revenues derived from sales to Asia. No
single customer accounted for more than 10% of IXYS' net revenues in fiscal
1998.
 
  In addition to new products developed for general use in target markets,
IXYS custom designs and manufactures products in which product design efforts
are coordinated with manufacturers. Custom products are achieved through IXYS'
wide selection of products and packaging options. IXYS provides product
samples and works directly with manufacturers in designing end-user products
using IXYS' semiconductors. Specific products are then delivered to the
manufacturers.
 
  IXYS markets its services and programs through advertisements, technical
articles and press releases that appear regularly in a variety of trade
publications, as well as through the dissemination of Company brochures, data
sheets and technical manuals. Additionally, IXYS participates in industry
trade shows on a regular basis. IXYS has also initiated a presence on the
Internet with a worldwide web page enabling engineers to access and download
technical information and data sheets.
 
  The majority of IXYS' revenues are derived from international sales.
International sales are subject to certain risks, including unexpected changes
in regulatory requirements, fluctuations in exchange rates, tariffs and other
barriers, political and economic instability, difficulties in staffing and
managing foreign subsidiary operations and potentially adverse tax
consequences.
 
  During fiscal 1996, 1997 and 1998, sales to independent distributors and
stocking representatives accounted for approximately 43%, 46% and 46% of net
revenues, respectively. Some of these distributors and stocking
representatives have a limited right to return unsold products to IXYS, and
there can be no assurance that such returns will not have a material adverse
effect on IXYS. These independent distributors and stocking representatives
generally are not subject to any minimum purchase requirements and can
discontinue marketing IXYS' products at any time upon proper notice.
Accordingly, IXYS must compete for the focus and sales efforts of its
distributors and stocking representatives. There can be no assurance that
IXYS' distributors and stocking representatives will continue to distribute
IXYS' products or do so successfully. Although IXYS believes that other
channels of distribution would be available if IXYS were to lose the services
of one or more of its independent distributors or stock representatives, there
can be no assurance that such loss would not have an adverse effect on its
results of operations.

RESEARCH AND DEVELOPMENT
 
  The ability of IXYS to successfully compete in the power semiconductor
market will be substantially dependent on its ability to design, develop and
introduce to the market on a timely basis new products offering technological
improvements. IXYS is a pioneer in technology with respect to higher power
IGBTs, IGBT modules and DCB and introduced the power semiconductor industry's
first 800 volt, 50 ampere IGBT and an IGBT and FRED combination high power
discrete device. While the time from sampling to volume production of new
power semiconductors products can take up to 18 months, power semiconductors
also have a product lifetime exceeding an average of 10 years. In fiscal 1998,
sales of products introduced within the last 4 years constituted approximately
20% of total net revenues. In fiscal 1998, IXYS introduced over 145 new part
types. During fiscal 1997 and 1998, IXYS' research and development expenses
were approximately $3.4 million and $3.3 million, respectively, and, at March
31, 1998, IXYS employed 18 people in engineering and research and development
activities. IXYS expects that it will continue to spend substantial funds on
research and development activities.
 
  IXYS is engaged in ongoing research and development efforts focused on
enhancements to existing products and the development of new products.
Currently, IXYS is pursuing research and development projects with respect to
increasing the voltage operating range of its MOS products beyond 1,800 volts,
improving the thermal conductivity of its DCB products, increasing the voltage
ratings of its bipolar products beyond 2,200 volts, developing 500 kilowatt
IGBT modules, developing a complete range of bipolar MOS products capable of
handling 1,400 to 2,000 volts and improving its multiple die module assembly
technology. Research and development activities are conducted in collaboration
with manufacturing activities to help expedite new products from the
development phase to manufacturing and more quickly implement new process
technologies.
 
  From time to time, IXYS has entered into agreements with customers to
develop specific products for inclusion in the customer's end product.
Pursuant to such agreements, the non-recurring engineering cost associated
with such development work, which is treated by IXYS as research, development
and engineering expense, is generally reimbursed by the customer. IXYS'
research and development efforts also include participation in technology
joint ventures with universities and research institutions. These joint
ventures allow research and development activities that would otherwise
require potentially cost prohibitive capital expenditures since the necessary
capital equipment is often available at research institutes and universities.
Through these joint ventures, IXYS is able to maximize its range of research
and development activities without defusing the focus of its in-house research
and development work and reduce its research and development costs. Research
and development projects currently being pursued through research institutes
or universities include MOS process simplification, new starting silicon wafer
development and new "higher power' semiconductor packaging and process
simplification.
 
  There can be no assurance that IXYS will be able to identify new products
successfully and develop and bring to market such new products or that IXYS
will be able to respond effectively to new technological changes or new
product announcements by others. There also can be no assurance that IXYS' new
products will be accepted by the market. Moreover, the end markets for IXYS'
products are subject to rapid technological change and there can be no
assurance that as such markets change IXYS' product offerings will remain
current and suitable for them.
 
PATENTS AND LICENSES
 
  IXYS holds 32 patents, including 27 which have been filed in the U.S. and 5
that have been filed in international jurisdictions. IXYS also has 17 patent
applications pending in the United States and 31 pending in international
jurisdictions. IXYS relies on a combination of patent rights, copyrights and
trade secrets to protect the proprietary elements of its products. IXYS'
policy is to file patent applications to protect technology, inventions and
improvements that are important to its business. There can be no assurance
that patents will issue from any of IXYS' pending applications or that any
claims allowed from existing or pending patents will be sufficiently broad to
protect IXYS' technology. While IXYS intends to protect its intellectual
property rights
 
                                      119
<PAGE>
 
vigorously, there can be no assurance that any patents held by IXYS will not
be challenged, invalidated or circumvented, or that the rights granted
thereunder will provide competitive advantages to IXYS.
 
  IXYS also seeks to protect its trade secrets and proprietary technology, in
part, through confidentiality agreements with employees, consultants and other
parties. There can be no assurance that these agreements will not be breached,
that IXYS will have adequate remedies for any breach, or that IXYS' trade
secrets will not otherwise become known to or independently developed by
others. In addition, the laws of some foreign countries do not protect IXYS'
proprietary rights to the same extent as the laws of the United States.
 
  While IXYS believes that its intellectual property rights are valuable, IXYS
also believes that, because of the rapid pace of technological change in the
industry, factors such as innovative skills, technical expertise, the ability
to adapt quickly to new technologies and evolving customer requirements,
product support and customer relations are of greater competitive
significance.
 
MANUFACTURING
 
  The production of IXYS' products is a highly complex and precise process.
IXYS manufactures its products in manufacturing facilities which are owned and
operated by IXYS and by utilizing outside wafer foundries and subcontract
assembly facilities. IXYS divides its manufacturing operations into two key
areas: wafer fabrication and assembly.
 
  Wafer Fabrication. IXYS owns an approximately 170,000 square foot
manufacturing facility in Lampertheim, Germany at which it manufactures
rectifiers and thyristors. IXYS has also retained the manufacturing of its
1,600 volt and higher power MOS devices at this facility in order to protect
its process technologies with respect to the fabrication of these products. In
addition to the Lampertheim facility, IXYS has an approximately 20,000 square
foot manufacturing facility in Santa Clara. IXYS designs and tests
substantially all of its IGBT and power MOSFET wafers in Santa Clara,
California and designs and tests its bipolar and custom MOS modules in
Lampertheim, Germany. IXYS believes that its in-house manufacturing
capabilities enable it to lower its manufacturing cost with respect to certain
products, bring products to the market more quickly than would be possible if
IXYS were required to rely exclusively on outside foundries, retain certain
proprietary aspects of its process technology and more quickly introduce new
process innovations.
 
  In addition to maintaining its own fabrication facility, IXYS establishes
alliances with selected foundries for wafer fabrication. This approach allows
IXYS to reduce substantial capital spending and manufacturing overhead
expenses, obtain competitive pricing and technologies and optimize production
schedules while retaining the flexibility to shift the production of its
products to a different or additional foundries for cost or performance
reasons. IXYS' product designs enable the production of its devices at
multiple foundries using well-established and cost-effective processes.
 
  IXYS relied on outside foundries for 44% of its wafer fabrication
requirements in fiscal 1998, and dependency on outside foundries is expected
to grow. IXYS has arrangements with five wafer foundries, of which two
foundries provide 99% of the wafers provided to IXYS by outside foundries.
IXYS has a supply agreement with one foundry, Samsung. Other than the
commitment with respect to the next two months' demand to be delivered
monthly, there are no obligations on the part of IXYS to order any minimum
quantities. See "Risk Factors--Risks Relating to the Business of IXYS--
Dependence on Third Parties for Wafer Fabrication and Assembly."
 
  Wafer fabrication of power semiconductors generally employs process
technology and equipment already proven in IC manufacturing. Power
semiconductors are manufactured using fabrication equipment that is one or
more generations behind the equipment used to fabricate state-of-the-art ICs.
Used fabrication equipment can be obtained at prices substantially less than
the original cost of such equipment or than the cost of current, state-of-the-
art equipment. Consequently, the fabrication of power semiconductors is less
capital intensive than the fabrication of ICs.
 
                                      120
<PAGE>
 
  Minute levels of contaminants in the manufacturing environment, difficulties
in the fabrication process, defects in the masks used to print circuits on a
wafer, manufacturing equipment failure, wafer breakage or other factors can
cause a substantial percentage of wafers to be rejected or numerous die on
each wafer to be nonfunctional. In the event that IXYS increases its
manufacturing output, there can be no assurance that IXYS will not experience
a decrease in manufacturing yields. Moreover, there can be no assurance that
IXYS in general will be able to maintain acceptable manufacturing yields in
the future. To the extent IXYS does not achieve acceptable manufacturing
yields or experiences product shipment delays, its business, financial
condition and results of operations would be materially and adversely
affected.
 
  There are significant risks associated with IXYS' reliance on outside
foundries, including the lack of assured supply of an adequate quantity of
semiconductor devices, control over delivery schedules and limited control
over quality assurance, manufacturing yields and production costs. IXYS'
foundries may from time to time experience lower than anticipated
manufacturing yields, particularly in connection with the introduction of new
products and the installation and start-up of new process technologies. There
can be no assurance that IXYS' foundries will not experience lower than
expected manufacturing yields in the future, which could materially and
adversely affect IXYS' business, financial condition and results of
operations.
 
  Although from time to time certain materials, including silicon wafers, have
been in short supply, to date IXYS has not experienced substantial delays in
obtaining raw materials which have materially adversely affected production.
There can be no assurance that IXYS will not experience such delays in the
future. As is typical in the industry, IXYS must allow for significant lead
time in delivery of its materials. See "Risk Factors--Dependence on
Suppliers."
 
  Packaging and Assembly. Generally, each die on IXYS' wafers is electrically
tested for performance, and most of the wafers are subsequently sent to
independent subcontract assembly facilities. Packaging or assembly is the
sequence of production steps that divide the wafer into individual chips and
enclose the chips in external structures (termed packages) that make them
useable in a circuit. Discrete manufacturing involves the assembly and
packaging of single die devices. Module manufacturing involves the assembly of
multiple devices within a single package. The resulting packages vary in
configuration, but all have leads which are used to mount the package through
holes in the customer's printed circuit boards.
 
  IXYS has equipment at, or manufacturing supply agreements with, assembly
subcontractors located in the Philippines, Portugal and Thailand in order to
take advantage of low assembly costs. Approximately 40% of IXYS' products are
assembled at these assembly facilities. Following assembly, IXYS' products are
returned to Santa Clara or Germany for testing and final inspection prior to
shipment to customers. IXYS' reliance on independent assemblers may subject
IXYS to supply constraints and longer manufacturing cycle times. IXYS from
time to time has experienced competition with respect to these contractors
from other manufacturers seeking assembly of circuits by independent
contractors. Although IXYS currently believes that alternative assembly
sources could be obtained, there can be no assurance that such alternative
sources could be quickly obtained. Foreign assembly is subject to risks
normally associated with foreign operations, including changes in local
governmental policies and the imposition of export controls or increased
import tariffs. See "Risk Factors".
 
COMPETITION
 
  The power semiconductor industry is intensely competitive and is
characterized by price competition, technological change, limited fabrication
capacity, international competition and manufacturing yield problems. The
ability of IXYS to compete successfully in its evolving industry depends on
factors both within and outside its control, including success in designing
and subcontracting the manufacture of new products that implement new
technologies, protection of Company products by effective utilization of
intellectual property laws, product quality, reliability, price, efficiency of
production, the pace at which customers incorporate IXYS' power semiconductors
into their products, success of competitors' products and general economic
conditions.
 
 
                                      121
<PAGE>
 
  IXYS encounters differing degrees of competition for its various products,
depending upon the type of product and the particular market served. Many of
IXYS' competitors are larger companies with greater technical, financial and
marketing resources than IXYS. The competitive factors in the market for IXYS'
products include overall functional performance of the products, quality,
price, reliability, breadth and availability of products, delivery time to the
customer and service.
 
  IXYS believes that it is able to effectively compete in the power
semiconductor market, and in the higher power segment of this market in
particular, because of (i) its broad product line in the higher power segment,
(ii) its ability to focus its technical resources on the development of higher
power semiconductors, (iii) its ability to target new market opportunities and
extensions of existing power semiconductor applications more quickly than may
be possible by a larger, more diversified organization and (iv) its ability
and willingness to collaborate with customers to provide custom products. IXYS
believes that it is one of only a few companies focused on the development and
marketing of higher power semiconductors capable of performing all of the
basic functions of power semiconductors.
 
  In the power MOSFET market, IXYS' competitors include Advanced Power
Technology, Inc. ("APT"), International Rectifier Corporation ("I.R."), Harris
Corporation ("Harris"), Motorola, Inc. ("Motorola") and SGS-Thomson
Microelectronics ("SGS"). IXYS targets the higher power segment of the MOSFET
market rather than the lower voltage, lower current segment of the market
dominated by IXYS' larger competitors. Currently, IXYS competes most directly
in this market with APT. IXYS believes that it is able to effectively compete
against APT by offering a wider range of products, improved body diode
performance at voltages over 500 volts and a greater number of high current
module packaging options.
 
  With respect to the IGBT market, IXYS competes primarily with Toshiba
Corporation, I.R., Harris, Siemens AG, Fuji Electric Company and Powerex, Inc.
("Powerex"). IXYS believes that its relatively quick time to market and its
package and product enhancements provide it with a competitive advantage over
most of its competitors.
 
  With respect to the FRED market, IXYS competes primarily with I.R., Harris,
Motorola and SGS. IXYS believes that FRED product performance is circuit
dependent but that in many chases, competitive products can be virtually
interchangeable. FREDs are necessary components of IGBT-based systems, and
IXYS' ability to package FREDs with IGBTs in one package without compromising
the performance of the IGBT allows it to be competitive with other larger
suppliers.
 
  IXYS' thyristors, standard diodes and thyristor/diode modules compete
primarily with the products of I.R., Eupec GmbH, Semikron International and
Powerex. As opposed to the market for IXYS' other products, this market tends
to be driven primarily by price and product availability. Therefore, IXYS
competes in this market through guaranteed inventory programs, custom
products, custom module capability and selective competitive pricing. See
"Risk Factors".
 
BACKLOG
 
  As of March 31, 1998, IXYS' backlog of orders was approximately $24.2
million, as compared with $25.3 million as of March 31, 1997. Backlog
represents firm orders anticipated to be shipped within the next 12 months.
IXYS' business and, to a large extent, that of the entire semiconductor
industry is characterized by short-term order and shipment schedules. Since
orders constituting IXYS' current backlog are subject to changes in delivery
schedules or to cancellation at the option of the purchaser without
significant penalty, backlog is not necessarily an indication of future
revenue.
 
EMPLOYEES
 
  As of March 31, 1998, IXYS employed 315 full-time employees, of whom 18 were
primarily engagedin engineering and research and development activities, 28 in
marketing, sales and customer support, 251 in
 
                                      122
<PAGE>
 
manufacturing and 18 in administration and finance. A high percentage of the
employees have advanced degrees, including 13 Ph.D.s. IXYS' future success
will be greatly dependent upon its ability to attract, motivate and retain
technical, marketing, sales and management personnel who are in great demand
in the semiconductor industry. Certain employees at IXYS' Lampertheim facility
are subject to collective bargaining agreements. IXYS believes that its
employee relations are good.
 
FACILITIES
 
  IXYS' administrative, marketing, development and manufacturing facilities
are located in Santa Clara, California and Lampertheim, Germany. The Santa
Clara facility consists of approximately 20,000 square feet under a lease
which expires in December 1998. IXYS has an option to extend the lease for
five years. The base rent under this lease is approximately $169,500 per year.
The Lampertheim facility, which is owned by IXYS, consists of approximately
170,000 square feet. IXYS believes that its current facilities will be
adequate through at least fiscal 1999 and that suitable additional space will
be available in the future as needed on commercially reasonably terms.
 
ENVIRONMENTAL MATTERS
 
  IXYS is subject to a variety of federal, state and local laws, rules and
regulations, and IXYS GmbH is subject to laws, rules and regulations in
Germany, related to the use, storage, handling, discharge and disposal of
certain chemicals and gases used in IXYS' manufacturing process. Any of those
regulations could require IXYS to acquire equipment or to incur substantial
other expenses to comply with environmental regulations. If substantial
additional expenses were incurred by IXYS, product costs could significantly
increase, thus materially adversely affecting IXYS' business, financial
condition and results of operations. IXYS believes that its activities conform
to present environmental regulations. Increasing public attention has,
however, been focused on the environmental impact of semiconductor operations.
While IXYS has not experienced any materially adverse effects on its
operations from environmental regulations, there can be no assurance that
changes in such regulations will not impose the need for additional capital
equipment or other requirements or restrict IXYS' ability to expand its
operations. Any failure by IXYS to comply with present or future environmental
laws rules and regulations could result in fines being imposed on IXYS,
suspension of production or cessation of operations, any of which could have a
material adverse effect on IXYS' business, financial condition and results of
operations. IXYS' business, financial condition and results of operations
would be subject to similar effects as a result of comparable laws and
regulations in Germany. See "Risk Factors--Risks Related to the Business of
IXYS."
 
  IXYS' leased Lampertheim facility is located in an industrial area in which
there is known environmental contamination. In connection with the purchase of
the Lampertheim facility, IXYS conducted an environmental assessment of the
site, and no material contamination under German law was found on the
Lampertheim facility premises. There can be no assurance that IXYS' business,
financial condition and results of operations will not be materially adversely
affected by this situation. See "Risk Factors--Risks Related to the Business
of IXYS."

 IXYS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
                                 OF OPERATIONS
 
  The following discussion of the financial condition and results of
operations of IXYS should be read in conjunction with the consolidated
financial statements and the related notes thereto included herein. The
discussion in this Joint Proxy Statement/Prospectus contains forward-looking
statements that involve risks and uncertainties. IXYS' actual results may
differ materially from the results discussed in the forward-looking
statements. Factors that could cause or contribute such differences include,
without limitation, those discussed in this section and the sections entitled
"Risk Factors" and "IXYS Business" as well as those discussed elsewhere in
this Joint Proxy Statement/Prospectus.
 
OVERVIEW
 
  IXYS was founded in 1983 to design, develop and market power semiconductors
used primarily in controlling energy in motor drives and power conversion.
IXYS' target market includes segments of the power semiconductor market that
require medium to higher power semiconductors, with a particular emphasis on
higher power semiconductors, which are those capable of processing greater
than 500 watts of power.
 
  IXYS has been an innovator in power MOS semiconductor products and
technologies since its inception. IXYS pioneered the high voltage, high
current MOSFET and IGBT technologies and was the industry's first developer
and manufacturer of a 1,000 volt, 100 amp IGBT, which has proven to be
superior in reliability and performance to traditional bipolar Darlington
transistors.
 
  In 1989, IXYS acquired the ABB AG power semiconductor operation in
Lampertheim, Germany from Zurich-based ABB, a world leader in power
generation, transmission, distribution equipment, industrial controls and
motor drives. Now called IXYS Semiconductor GmbH, the power semiconductor
operation in Lampertheim is recognized for pioneering work in DCB packaging
technology. The group also developed a line of FREDs that significantly reduce
energy losses in motor control and UPS applications. IXYS Semiconductor GmbH
provides IXYS with a strong foothold in the European Community ("EC") and
positions IXYS to take advantage of tariff and import incentives to EC-based
entities.
 
  In January 1993, in answer to continuing operational losses, IXYS underwent
a reorganization of its upper level management structure. Subsequent cost
cutting in its US operations as well as in its Lampertheim facility allowed
IXYS to operate more efficiently and achieve profitability.
 
  In 1995, IXYS reincorporated in Delaware. Also in 1995, ABB AG converted
approximately $10.5 million in debt owed to it by IXYS into IXYS Series B
Preferred Stock.
 
  In January 1998, IXYS completed the purchase of the Lampertheim facility
previously leased from ABB AG. This facility is approximately 170,000 square
feet and houses IXYS' Lampertheim offices and manufacturing operations. ABB AG
leases some office space in this facility. IXYS feels that the Lampertheim
facility is sufficient to serve its needs in the module and bipolar product
lines for the foreseeable future.
 
RESULTS OF OPERATIONS--YEARS ENDED MARCH 31, 1998 AND MARCH 31, 1997
 
  Net Revenue. IXYS' net revenues for fiscal 1998 were $56.9 million, a 2.9%
increase from revenue of $55.3 million in 1997. The increase is primarily
related to an increase of approximately 12% in units shipped in 1998 as
compared to 1997, offset by a 10% decrease in average selling prices.
International net revenue represents $35.8 million for fiscal 1998 or 63% of
total net revenue as compared to $34.3 million for fiscal 1997 or 62% of net
revenue.
 
  Gross Margin. IXYS' gross margin for 1998 was 33% as compared to 38% in
1997. The decrease in gross margin is due to average selling prices which, in
response to competition, declined at a faster rate than IXYS' ability to
reduce its costs.International gross margin for 1998 was 25% as compared to
35% in 1997. Domestic gross margin for 1998 was 42% as compared 44% in 1997.
 
                                      125

  Research, Development and Engineering ("R&D"). For the fiscal year ended
1998 R&D was $3.3 million or 5.8% of net revenues, as compared to $3.0
million, or 5.4%, for fiscal year 1997. R&D expenses increase was due to
higher engineering headcount in 1998.
 
  Selling, General, Administrative Expenses ("SG&A"). For the fiscal year
1998, SG&A was $8.4 million (14.8% of net sales) as compared to $9.0 million
(16.3% of net sales) in fiscal year 1997. In absolute dollars, SG&A decreased
by $600,000 reflecting significantly lower costs associated with IXYS' defense
of a patent claim made by Harris Corporation (the "Harris Matter"), which was
settled in fiscal 1998.
 
  Interest Expense. During 1998, interest expense was $431,000 compared to
$116,000 in 1997. The increase in interest expense is due to higher average
borrowings in 1998 as compared to 1997.
 
  Other Income (Expense), Net. Other income in fiscal 1998 includes $3.7
million attributable to the settlement of the Harris Matter.
 
  Provision/Benefit For Income Taxes. The 1998 provision for income taxes
reflected an effective tax rate of 41.0% in 1998 compared to 47.2% in 1997.
IXYS' effective tax rate approximates statutory foreign and US federal and
state rates.
 
  Net Income. IXYS had net income of $6.1 million, or $0.03 per share on a
diluted basis, for 1998 compared to $4.4 million, or $0.02 per share on a
diluted basis, for 1997. The increase in net income is primarily attributed to
other income of $3.7 million which represents the proceeds from the settlement
of the Harris Matter.
 
FISCAL YEARS ENDED MARCH 31, 1997 AND 1996
 
  Net Revenue. IXYS' net revenues for fiscal 1997 were $55.3 million, a 3.7%
decrease from net revenues of $57.4 million in fiscal 1996. The decrease is
primarily related to lower demand and therefore fewer units shipped in 1997 as
compared to 1996, primarily in Europe. International net revenue represents
$34.3 million for fiscal 1997 or 62% of total net revenue as compared to $37.7
million for fiscal 1996 or 66% of net revenue.
 
  Gross Margin. IXYS' gross margin in each of fiscal 1997 and fiscal 1996 was
approximately 38%. International gross margin for 1997 was 35% as compared to
33% in 1996. Domestic gross margin for 1997 was 44% as compared to 48% in
1996.
 
  Research, Development and Engineering Expenses. For fiscal 1997, R&D
expenses were $3.0 million, or 5.9% of net revenues, as compared to $3.4
million, or 6.0% of net revenues for fiscal 1996. The decrease in R&D expenses
from 1996 to 1997 was the result of lower engineering headcount in 1997.
 
  Selling, General, Administrative Expenses. For fiscal 1997, SG&A was $8.9
million, or 16.1% of net revenues, as compared to $9.4 million, or 16.4% of
net revenues, in fiscal 1996. SG&A decreased by $500,000 from 1996 to 1997
reflecting declining costs associated with IXYS' defense of the litigation
involving the Harris Matter.
 
  Interest Expense. During fiscal 1997, interest expense was $116,000 compared
to $78,000 in fiscal 1996.
 
  Provision Benefit for Income Taxes. The fiscal 1997 provision for income
taxes of $3.9 million reflected an effective tax rate of 47.2% in 1997
compared to a tax benefit of $4.3 million in fiscal 1996. The benefit in 1996
reflects the reversal of the deferred tax valuation allowance, based on
management's opinion that it is more likely than not that the net deferred tax
asset will be realized in the future. IXYS' effective tax rate approximates
statutory foreign and U.S. federal and state rates.
 
 
                                      126
<PAGE>
 
  Net Income. IXYS had net income of $4.4 million, or $0.02 per share on a
diluted basis, for fiscal 1997 compared to $11.6 million, or $0.09 per share
on a diluted basis, for fiscal 1996. The decrease in net income from 1996 to
1997 is primarily attributable to the income tax benefit of $4.3 million
applicable to 1996 and the income tax provision of $3.9 million applicable to
1997.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  IXYS has financed its operations to date through the private sale of equity,
lease financing, and bank borrowings. As of March 31, 1998, cash and cash
equivalents were $9.6 million, an increase of $3.0 million from cash and cash
equivalents of $6.6 million at March 31, 1997. The increase in cash and cash
equivalents was primarily due to cash generated from operations of $3.3
million.
 
  Line of credit facilities available to IXYS are as follows: A line of credit
with a U.S. bank that as of March 31, 1998 consists of a $5.0 million
commitment amount which is available through August 1999. The line bears
interest at the bank's prime rate (8.50% at March 31, 1998). The line is
collateralized by certain assets and contains certain general and financial
covenants which include provisions stating that IXYS cannot incur additional
debt or pledge assets without the prior approval of such bank. At March 31,
1998, IXYS had drawn $2.1 million against such line of credit.
 
  As of March 31, 1998, IXYS had cash deposits with a financial institution in
the amount of $950,000, which is restricted as to use and represents
compensating balances on future discounted acceptances and letters of credit.
 
  During February 1997, IXYS entered into an agreement to purchase the
property on which the German subsidiary operates for DM 13,250,000 (U.S. $7.9
million at March 31, 1997). The purchase closed in January, 1998. The purchase
price was entirely financed by a loan from a bank in Germany with principal
and interest payable over twelve years at a fixed interest rate of 5.4% per
annum until August 2001, and at Market rates thereafter.
 
  The accounts receivable at March 31, 1998 were 22% greater than the accounts
receivable at March 31, 1997 as a consequence of greater revenues during the
period immediately preceding March 31, 1998 as compared to the period
immediately preceding March 31, 1997. The inventories at March 31, 1998 were
47% greater than the inventories at March 31, 1997 as a consequence of
expectations for increased orders deliverable during the period immediately
following March 31, 1998 as compared to expectations for the period
immediately following March 31, 1997 and as a consequence of relatively
depressed inventory levels at March 31, 1997. Plant and equipment at March 31,
1998 increased 212% as compared to March 31, 1997, as a result of the purchase
of the facility in Germany.
 
  IXYS evaluates the acquisition of businesses, products or technologies that
complement IXYS' business. Any such transactions, if consummated, may use a
portion of the IXYS working capital or require the issuance of equity
securities which may result in further dilution to the IXYS stockholders.
 
  IXYS believes that cash generated from operations, if any, and banking
facilities will be sufficient to meet its cash requirements through fiscal
1999. To the extent that funds generated from operations, together with
banking facilities are insufficient to meet its capital requirements, IXYS
will be required to raise additional funds. No assurance can be given that
additional financing will be available or, if available, that it will be
available on acceptable terms. The lack of such financing, if needed, would
have a material adverse effect on IXYS' business, financial condition and
results of operations.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
  In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130 (SFAS 130), "Reporting Comprehensive
Income." This statement establishes requirements for disclosure of
comprehensive income and becomes effective for IXYS for fiscal year 1999, with
reclassification of earlier financial statements for comparative purposes.
Comprehensive income generally
 
                                      127
<PAGE>
 
represents all changes in stockholders' equity except those resulting from
investments or contributions by stockholders. IXYS is evaluating alternative
formats for presenting this information, but does not expect this
pronouncement to materially impact IXYS' results of operations.
 
  In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131 (SFAS 131), "Disclosures about Segments
of an Enterprise and Related Information". This statement establishes
standards for disclosure about operating segments in annual financial
statements and selected information in interim financial reports. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. This statement supersedes Statement of
Financial Accounting Standards No. 14, "Financial Reporting for Segments of a
Business Enterprise." The new standard becomes effective for IXYS' fiscal year
1999, and requires that comparative information from earlier years be restated
to conform to the requirements of this standard. IXYS is evaluating the
requirements of SFAS 131 and the effects, if any, on IXYS' current reporting
and disclosures.

                      COMPARISON OF STOCKHOLDERS' RIGHTS
 
  The following is a summary of certain material differences between the
rights of holders of Paradigm Common Stock and Paradigm Preferred Stock on the
one hand and IXYS Common Stock and IXYS Preferred Stock on the other. Because
each of Paradigm and IXYS is organized under the laws of Delaware, these
differences arise from various provisions of the Restated Certificate of
Incorporation (the "Paradigm Certificate") and the Bylaws (the "Paradigm
Bylaws") of Paradigm, and the Restated Certificate of Incorporation (the "IXYS
Certificate") and the Bylaws (the "IXYS Bylaws") of IXYS. The following
discussion is meant only to summarize certain of such differences and does not
purport to be complete. Copies of the Paradigm Certificate and the Paradigm
Bylaws may be obtained from Paradigm. See "Available Information."
 
VOTING
 
  Paradigm. Except as otherwise required by law, the holders of shares of
Paradigm Common Stock are entitled to one vote for each share held. Except as
otherwise set forth in the Paradigm Certificate, the holders of shares of
Paradigm Preferred Stock are not entitled to vote, but would be entitled to
one vote for each share of Paradigm Common Stock issued upon conversion of the
Paradigm Preferred Stock.
 
  IXYS. Except as otherwise required by law, the holders of shares of IXYS
Preferred Stock and IXYS Common Stock are entitled to one vote for each share
held. Except as otherwise set forth in the IXYS Certificate or under
applicable law, the holders of shares of IXYS Preferred Stock are entitled to
vote together with the IXYS Common Stock as a single class on all actions to
be taken by the stockholders of IXYS, and each share of IXYS Preferred Stock
entitles the holder to such number of votes per share as shall equal the
number of whole shares of IXYS Common Stock into which each share is
convertible.
 
DIRECTORS
 
  Paradigm. The Paradigm Bylaws provide that the number of Paradigm directors
shall be determined from time to time by resolution of the Paradigm Board
(which currently sets the size of the Paradigm Board at three (3) directors),
and the initial Paradigm Board shall consist of four (4) directors. The
Paradigm directors shall be elected at the annual meeting or any special
meeting of the Paradigm stockholders and each director so elected shall hold
office until the next annual meeting and until his or her successor is duly
elected and qualified or until his earlier resignation or removal. Unless
otherwise restricted by statute, the Paradigm Certificate or the Paradigm
Bylaws, any director or the entire Paradigm Board may be removed, with or
without cause, by the holders of at least a majority of the shares entitled to
vote at an election of directors. Vacancies may be filled by a majority of the
remaining directors, though less than a quorum, or by a sole remaining
director, unless otherwise provided in the Paradigm Certificate. The Paradigm
stockholders may elect a director or directors at any time to fill any vacancy
or vacancies not filled by the Paradigm directors.
 
  IXYS. The IXYS Bylaws provide that the IXYS Board shall consist of three (3)
members, which number can be amended from time to time by the IXYS Board. The
IXYS Certificate does not divide the IXYS Board into separate classes. The
IXYS directors shall be elected at the annual meeting of IXYS stockholders,
and each director so elected shall hold office until the next annual meeting
and until his or her successor is duly elected and qualified or until his or
her earlier resignation or removal. The IXYS Bylaws provide that no reduction
of the number of directors shall have the effect of removing a director before
his or her term expires. A director may be removed with cause by the holders
of a majority of the shares then entitled to vote at an election of directors,
or without cause by the affirmative note of the holders of at least sixty-six
and two-thirds percent (66 2/3%) of the shares then entitled to vote at an
election of directors. In addition, the IXYS Bylaws provide that vacancies in
the IXYS Board may be filled by the vote of a majority of the remaining
members of the IXYS Board, even though less than a quorum of the IXYS Board,
and that vacancies resulting from resignations may be filled by the vote of a
majority of the directors then in office (including the resigning director).

LIABILITY OF OFFICERS AND DIRECTORS; INDEMNIFICATION
 
  Paradigm. The Paradigm Certificate provides that a Paradigm director shall
not be personally liable, to the fullest extent permitted by the DGCL, to
Paradigm or its stockholders for monetary damages for breach of fiduciary duty
as a Paradigm director, except for liability for any breach of the director's
duty of loyalty to Paradigm or its stockholders, for acts or omissions not in
good faith or which involved intentional misconduct or a knowing violation of
the law, under section 174 of the DGCL, or for any transaction from which the
Paradigm director derived an improper personal benefit. Any repeal or
modification of the foregoing provisions by the Paradigm stockholders will not
adversely affect any right or protection of a Paradigm director existing at
the time of such repeal or modification. In addition to the indemnification
provided for under the Paradigm Certificate, each Paradigm executive officer
and director has entered into Indemnification Agreements with Paradigm.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling Paradigm
pursuant to the foregoing provisions, Paradigm has been informed that in the
opinion of the SEC such indemnification is against public policy as expressed
in the Securities Act and is therefore unenforceable.
 
  IXYS. The IXYS Certificate provides that an IXYS director shall not be
personally liable, to the fullest extent permitted by the DGCL, to IXYS or its
stockholders for monetary damages for breach of fiduciary duty as an IXYS
director, except for liability for any breach of the director's duty of
loyalty to Paradigm or its stockholders, for act or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
under section 174 of the DGCL or for any transaction from which the director
derived an improper personal benefit. Any repeal or modification of the
foregoing provisions by the IXYS stockholders shall not adversely affect any
right or protection of an IXYS director existing at the time of the alleged
occurrence or any action or omission to act giving rise to liability.
 
SPECIAL MEETINGS; WRITTEN CONSENTS
 
  Paradigm. Special meetings of the Paradigm stockholders may be called for
any purpose or purposes, unless otherwise prescribed by the statute or by the
Paradigm Certificate, at the request of the Chairman of the Paradigm Board,
the President or the Paradigm Board or by any one Paradigm stockholder holding
not less than twenty percent (20%) of the voting power of Paradigm. Such

other than the IXYS Board, the request shall be in writing, and such request
shall specify the purpose or purposes of the proposed meeting. Business
transacted at any special meeting of IXYS stockholders shall be limited to the
purposes stated in the notice. The IXYS stockholders are not permitted to take
any action by written consent after the closing of a qualified initial public
offering of IXYS shares.

date. In connection with the 1995 Management Stock Awards, an aggregate of
67,565,000 shares of IXYS Common Stock were granted at a price of $0.013 per
share to the IXYS Executives. Such shares were paid for by the IXYS Executives
with recourse promissory notes and vest on a five-year schedule. As of January
1, 1998, Dr. Zommer's and Mr. Agbayani's shares had fully vested. As of
December 31, 1997, 1,140,708 shares remain unvested for Mr. Fassler, 1,140,708
shares remain unvested for Mr. Ingram and 1,052,962 shares remain unvested for
Mr. Kane. Mr. Hirsch resigned from his employment with IXYS on December 8,
1997.

  On November 12, 1996, IXYS entered into a loan agreement with Dr. Zommer in
the amount of $75,294.38 for the purpose of assisting Dr. Zommer in acquiring
a personal residence (the "Loan"). As of February 17, 1998, $75,294 remained
outstanding under the Loan. In connection with the Loan, Dr. Zommer and IXYS
entered into a Stock Pledge Agreement whereby Dr. Zommer granted IXYS a first
priority security interest in any and all shares of IXYS Common Stock owned or
acquired by him. IXYS may collect on such collateral in the event Dr. Zommer
defaults on the Loan.
 
  In January 1998, IXYS completed its purchase from ABB AG certain real
property and building facilities located in Lampertheim, Germany. Such real
property is currently used by IXYS' subsidiary, IXYS Semiconductor GmbH, for
its operations. IXYS paid approximately 13.250 million deutschmarks for such
real property pursuant to an agreement with ABB AG dated as of February 26,
1997.
 
  ABB AG serves as a distributor for IXYS throughout Europe on substantially
the same terms and conditions as those entered into by IXYS with its other
distributors. In addition, ABB AG is a customer of IXYS and has purchased
semiconductor devices from IXYS. Sales to ABB AG account for less than 5% of
IXYS' total sales.
 
  Dr. Rolf Karg, who is an executive officer of ABB AG, has served as a
director of IXYS since May 17, 1996.
 
  IXYS believes that the foregoing transactions were in its best interests and
were on terms no less favorable to IXYS than could be obtained from
unaffiliated third parties.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
 of Paradigm Technology, Inc.
 
  In our opinion, the accompanying balance sheets and the related statements
of operations, of stockholders' equity and of cash flows present fairly, in
all material respects, the financial position of Paradigm Technology, Inc. at
December 31, 1996 and 1997, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of Paradigm's management; our responsibility
is to express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.
 
  The accompanying financial statements have been prepared assuming that
Paradigm will continue as a going concern. As discussed in Note 1 to the
financial statements, Paradigm has suffered recurring losses from operations
and will require additional cash to fund 1998 operations. These matters raise
substantial doubt about its ability to continue as a going concern.
Management's plans in regard to these matters are described in Note 1. The
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1--PARADIGM AND ITS BUSINESS:
 
  Paradigm Technology, Inc. ("Paradigm" or the "Company") was originally
incorporated in California in January 1987. Pursuant to the May 24, 1994,
Third Amended Joint Plan of Reorganization (the "Plan") under Chapter 11 of
the United States Bankruptcy Code, amended Articles of Incorporation were
filed. On June 7, 1994, the Court confirmed the Plan, which became effective
on June 21, 1994. Paradigm reincorporated in Delaware effective June 22, 1995,
which involved the exchange of Paradigm's post-Reorganization common and
preferred stock into shares of the Delaware Company stock. Pursuant to the
reincorporation, Paradigm has authorized 25,000,000 shares of $0.01 par value
common stock and 5,000,000 shares of $0.01 par value preferred stock.
 
  Paradigm markets high speed, high density Static Random Access Memory
("SRAM") products for uses in telecommunication devices, workstations and high
performance PCs to OEMs and distributors in the United States, Europe and the
Far East.
 
  The SRAM business is highly cyclical and has been subject to significant
downturns at various times that have been characterized by diminished product
demand, production overcapacity, and accelerated erosion of average selling
prices. From the latter part of 1995 through 1997, the market for certain SRAM
devices experienced an excess supply relative to demand which resulted in a
significant downward trend in prices.
 
  The selling price that Paradigm is able to command for its products is
highly dependent on industry-wide production capacity and demand. In this
regard, Paradigm did experience rapid erosion in product pricing during 1996
and 1997 which was not within the control of Paradigm. Paradigm could continue
to experience a downward trend in product pricing which could further
adversely effect Paradigm's operating results.
 
  Paradigm's recent operations have consumed substantial amounts of cash.
During 1997, Paradigm completed the private placement of Series A Preferred
Stock, Series B Preferred Stock, and Series C Preferred Stock for net proceeds
of approximately $4,673,000. Paradigm believes that it will require additional
cash infusion from similar or related private placements and other sources of
liquidity, such as asset sales and equipment financing to meet Paradigm's
projected working capital and other cash requirements in 1998. See Note 13.
 
NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
REVERSE STOCK SPLIT
 
  Share information for all periods has been retroactively adjusted to reflect
a 10-for-1 reverse stock split of common stock effected on May 1, 1998.
 
BASIS OF PRESENTATION
 
  The preparation of these financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could vary from those
estimates.
 
CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
  Paradigm considers all highly liquid investments purchased with an initial
maturity of 90 days or less to be cash equivalents and investments with
original maturities of greater than 90 days to be short-term investments.
Paradigm accounts for its short-term investments in accordance with Statement
of Financial Accounting Standards No. 115, "Accounting for Certain Investments
in Debt and Equity Securities" ("SFAS 115"). As of December 31, 1996 and 1997,
Paradigm had no short-term investments.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
CONCENTRATION OF CREDIT RISK
 
  Export sales, primarily to Europe and the Far East, represent 28%, 25%, and
12% of total sales for the years ended December 31, 1995, December 31, 1996,
and December 31, 1997, respectively. Paradigm's sales have been denominated in
U.S. dollars.
 
  Paradigm performs ongoing credit evaluations of its customers and generally
does not require collateral. The following table summarizes the percentage of
net sales to significant customers:

     Customer F ..................................      --        --        10%
</TABLE>
 
  As of December 31, 1996, accounts receivable from three customers accounted
for approximately 16%, 17% and 18% of total gross accounts receivable,
respectively. As of December 31, 1997, accounts receivable from three
customers accounted for approximately 25%, 25%, and 15% of total gross
accounts receivable, respectively. Paradigm maintains allowances for potential
credit losses based upon expected collectibility of all accounts receivable.
 
INVENTORY
 
  Inventory is stated at the lower of cost (determined on a first-in, first-
out method) or market.
 
PROPERTY AND EQUIPMENT
 
  Property and equipment are stated at cost, net of certain equipment
impairment charges. Depreciation is computed using the straight-line method
over estimated useful lives of three to five years. Leasehold improvements are
amortized over the shorter of the lease term or the estimated useful life.
 
  Pursuant to Statement of Financial Accounting Standards No. 121, "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to be
disposed of" ("SFAS 121"), Paradigm reviews long-lived assets, including the
identifiable intangible assets and goodwill and will record impairment charges
whenever events or changes in circumstances indicate the carrying amount of
the assets may not be fully recoverable.
 
REVENUE RECOGNITION
 
  Revenue from product sales is generally recognized upon shipment and a
reserve is provided for estimated returns. Paradigm's sales to distributors
are made under agreements allowing certain rights of return and price
protection on products unsold by the distributors. Accordingly, Paradigm
defers recognition of revenue on such sales until the products are sold by the
distributors.
 
RESEARCH AND DEVELOPMENT
 
  Research and development expenses are charged to the statement of operations
as incurred.
 
STOCK BASED COMPENSATION
 
  Statement of Financial Accounting Standards No. 123, "Accounting for Stock-
Based Compensation" ("SFAS 123"), encourages, but does not require companies
to record compensation cost for stock-based employee compensation plans based
on the fair value of options granted. Paradigm has chosen to continue to

                           PARADIGM TECHNOLOGY, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
account for stock-based compensation using the intrinsic value method
prescribed in Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees." Accordingly, compensation for stock options is
measured as the excess, if any, of the quoted market price of Paradigm's stock
at the date of the grant over the amount an employee must pay to acquire the
stock. Paradigm provides additional pro forma disclosures as required by FAS
123.
 
NET INCOME (LOSS) PER SHARE
 
  During the quarter ended December 31, 1997, Paradigm adopted Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128").
SFAS 128 requires presentation of both Basic EPS and Diluted EPS. Basic EPS is
computed by dividing net income available to common stockholders (numerator)
by the weighted average number of common shares outstanding (denominator)
during the period. Diluted EPS gives effect to all dilutive potential common
shares outstanding during a period. In computing Diluted EPS, the average
price for the period is used in determining the number of shares assumed to be
purchased from exercise of stock options, warrants and Convertible Preferred
Stock. Net income (loss) per share for all prior periods presented has been
restated to conform to the provisions of SFAS 128.
 
  Following is a reconciliation of the numerators and denominators of the
Basic and Diluted EPS computations for the periods presented below:

</TABLE>
 
  Options to purchase 112,900 shares of common stock at prices ranging from
$2.50 to $20.60 per share were outstanding during 1997 and approximately
1,067,000 shares issuable on the conversion of the 257 shares of Convertible
Preferred Stock, based on the conversion factor at December 31, 1997, were not
included in the computation of diluted EPS because the inclusion of such
options and shares would have been antidilutive.
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
  In June 1997, the FASB issued SFAS 130, "Reporting Comprehensive Income."
SFAS 130 establishes standards for reporting comprehensive income and its
components in a financial statement. Comprehensive income as defined includes
all changes in equity (net assets) during a period from non-owner sources.
Examples of items to be included in comprehensive income, which are excluded
from net income, include foreign currency translation adjustment and
unrealized gain/loss on available for sale securities. The disclosure
prescribed by SFAS must be made beginning with the first quarter of fiscal
1998 and will have no impact on Paradigm's financial position or results of
operations.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
  In June 1997, the FASB issued SFAS 131, "Disclosure about Segments of an
Enterprise and Related Information." This statement establishes standards for
the way companies report information about operating segments in annual
financial statements. It also establishes standards for related disclosures
about products and services, geographic areas, and major customers. The
disclosures prescribed by SFAS 131 are effective in fiscal 1998.

NOTE 4--RELATED PARTY TRANSACTIONS:
 
  As a result of Paradigm's 1994 reorganization, certain of Paradigm's
creditors became stockholders. Transactions with stockholders consist of the
following:
 
  During the years ended December 31, 1995, 1996 and 1997, Paradigm purchased
product with a value of $3,237,000, $6,111,000 and $2,667,000, respectively,
from NKK Corporation ("NKK"). There was no amount due NKK at December 31, 1996
or December 31, 1997.
 
  In April 1995, NKK and Paradigm modified their previous technology license
and development agreements. This 1995 agreement provides for payment of
royalties to Paradigm by NKK on certain quantities of 1M SRAM's sold and, with
certain exceptions, cancels further obligations of each party to deliver
technology improvements or design updates to the other.
 
  On April 28, 1995, pursuant to certain agreements with certain of Paradigm's
stockholders, Atmel Corporation ("Atmel") acquired 42,500 shares of common
stock from Paradigm, 30,000 shares of common stock from certain stockholders
of Paradigm who had been unsecured creditors of Paradigm as of the
reorganization, and 12,805 shares of common stock from Paradigm's equipment
lessors all of which shares were purchased at a price of $80.00 per share (the
"Atmel Stock"). Atmel also acquired certain warrants to purchase
 
                                     F-10
<PAGE>
 
                           PARADIGM TECHNOLOGY, INC.
 
                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
17,500 shares of common stock at an exercise price of $10.00 per share, for a
purchase price of $70.00 per share subject to the warrants. In connection with
these transactions, Paradigm entered into an Agreement with Atmel (the "Stock
Purchase Agreement") pursuant to which Atmel agreed to certain transfer
restrictions for a period of three years. Atmel also agreed to certain
standstill provisions, including an agreement not to increase its beneficial
ownership above 19.9% of the voting power of Paradigm on a fully diluted basis
for a period of five years from the date of the Stock Purchase Agreement. The
foregoing restrictions terminate on the date on which a person or entity
acquires more than 50% of the voting power of Paradigm. In addition, Atmel
agreed that, for a period of ten years from the date of the Stock Purchase
Agreement, it will vote the Atmel Stock in proportion to the votes cast by the
other stockholders of Paradigm, except with respect to certain material
events. The voting and standstill restrictions terminate at such time as Atmel
beneficially owns less than 5% of the common stock of Paradigm. On April 28,
1995, Atmel also entered into a Licensing and Manufacturing Agreement (the
"Agreement") with Paradigm. This Agreement provides Atmel with a nonexclusive,
royalty bearing license to manufacture, use and sell certain of Paradigm's
products. The royalty fee is based on a percentage of the average selling
price of the products sold. In addition, under the Agreement, a certain wafer
manufacturing capacity per week has been made available to Paradigm by Atmel.
The Agreement does not include a purchase commitment by Paradigm. However, to
the extent Paradigm provides Atmel with its three-month demand forecast, it is
committed to purchase the three-month forecasted quantities. No obligation to
purchase wafers existed as of December 31, 1997. The price of the wafers has
been fixed at the current fair market value. The Agreement expires on April
28, 2000. There were no purchases from Atmel in 1997, and there was no amount
due Atmel at December 31, 1997. The value of product purchased from Atmel in
the year ended December 31, 1996 was $429,000 of which $140,000 is included in
the accounts payable, related party balance at December 31, 1996.
 
NOTE 5--LINE OF CREDIT AND DEBT OBLIGATIONS:
 
  In November 1996, Paradigm replaced an existing line of credit with a new
line of credit from Greyrock Business Credit with a borrowing limit of
$6,000,000. Borrowings under this line of credit were limited to 80% of
eligible receivables and interest was at the greater of LIBOR plus 5.25% or
9%. At December 31, 1996, the outstanding balance under this line of credit
was $2,015,000.
 
  In October 1997, Paradigm renewed its line of credit with Greyrock Business
Credit. Borrowing is limited to the lesser of $5,000,000 or the sum of (a) 80%
of the amount of eligible receivables owing from original equipment
manufacturers; plus (b) 70% of the amount of eligible receivables owing from
distributors. The interest rate remained unchanged from the November 1996
agreement. The line of credit is subject to renewal again in October 1998,
unless prior notice is given by either party to terminate the agreement. The
line of credit is secured by Paradigm's trade receivables, inventory,
equipment and general intangibles. At December 31, 1997, the outstanding
balance under the line of credit was $1,719,000.
 
  Debt obligations aggregating $534,000 consist of outstanding promissory
notes which bear interest at rates ranging from 8.0% to 19.8% at December 31,
1997, and are repayable at various dates through 1999. These notes are secured
by the related equipment purchased.
 
NOTE 6--NEWLOGIC ACQUISITION:
 
  In June 1996, Paradigm acquired, through a stock purchase and merger
transaction, NewLogic, a company which develops and manufactures logic designs
with large memory arrays. In exchange for its purchase of the NewLogic capital
stock, Paradigm issued 31,439 shares of Paradigm's common stock, with a market
value of approximately $2,656,000, and approximately $825,000 in cash. In
addition, Paradigm incurred transaction costs of approximately $237,000. The
fair value of NewLogic's tangible net assets at the date of acquisition was a
deficit of $373,000. Approximately $3,841,000 of the purchase price in excess
of the fair market value of the net
 
                                     F-11

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
tangible assets was allocated to in-process technology which Paradigm wrote
off in the quarter ended June 30, 1996. Approximately $250,000 was allocated
to other intangibles. The unamortized balance of these other intangibles was
written off in connection of the shutdown of NewLogic in early 1997.
 
  Paradigm accounted for this acquisition using the purchase method of
accounting and accordingly, the results of operations and cash flows of the
acquisition were included only from the date of acquisition. Excluding the
$3,841,000 write-off of purchased in-process technology, the pro forma impact
on Paradigm's results of operations had the acquisition been consummated on
January 1, 1995 was not materially different from the results presented in the
accompanying statement of operations.
 
NOTE 7--CONVERTIBLE PREFERRED STOCK:
 
  On January 23, 1997, Paradigm sold a total of 200 shares of Series A
Preferred Stock in a private placement, at a price of $10,000 per share, for
total proceeds (net of payments to third parties) of approximately $1,880,000.
The Series A Preferred Stock includes cumulative dividends at 5% per annum.
The Series A Preferred Stock also includes an embedded discount on conversion
which was accreted from the issuance date through April 23, 1997, the date
upon which the Series A Preferred Stock became convertible. The accretion of
the embedded discount and the cumulative dividends were treated as a charge to
accumulated deficit. Also in connection with the sale of the Series A
Preferred Stock Paradigm issued a warrant to purchase 15,000 shares of its
Common Stock for $41.25 per share. The warrant is exercisable until January
22, 2000. Paradigm valued these warrants at $67,000 using the Black/Scholes
option pricing model.
 
  The Series A Preferred Stock is convertible at the option of the holder into
the number of fully paid and non-assessable shares of Common Stock as is
determined by dividing (A) the sum of (1) $10,000 plus (2) the amount of all
accrued but unpaid or accumulated dividends on the shares of Series A
Preferred Stock being converted by (B) the Series A Conversion Price in effect
at the time of conversion. The "Series A Conversion Price" is equal to the
lower of (i) $22.50 or (ii) eighty-two percent (82%) of the average closing
bid price of a share of Common Stock as quoted on the SCM (or quoted on such
other national or regional securities exchange or automated quotation system
upon which the Common Stock is listed and principally traded) over the five
(5) consecutive trading days immediately preceding the date of notice of
conversion of the Series A Preferred Stock. During 1997, the holders of the
Series A Preferred Stock converted 149 shares of the Series A Preferred Stock
into 239,605 shares of Paradigm's Common Stock. As of December 31, 1997, there
were 51 shares of the Series A Preferred Stock outstanding.
 
  On July 22, 1997, Paradigm sold a total of 200 shares of Series B Preferred
Stock in a private placement at a price of $10,000 per share, for total
proceeds (net of payments to third parties) of approximately $1,870,000. The
Series B Preferred Stock includes cumulative dividends at 5% per annum. The
Series B Preferred Stock also includes an embedded discount on conversion
which was accreted from the issuance date through September 10, 1997, the date
upon which the Series B Preferred Stock became convertible. The accretion of
the embedded discount and the cumulative dividends have been treated as a
charge to accumulated deficit.
 
  The Series B Preferred Stock is convertible at the option of the holder into
the number of fully paid and non-assessable shares of Common Stock as is
determined by dividing (A) the sum of (1) $10,000 plus (2) the amount of all
accrued but unpaid or accumulated dividends on the shares of Series B
Preferred Stock being converted by (B) the Series B Conversion Price in effect
at the time of conversion. The "Series B Conversion Price" will be equal to
the lower of (i) $13.75 or (ii) eighty-two percent (82%) of the average
closing bid price of a share of Common Stock as quoted on the SCM (or quoted
on such other national or regional securities exchange or automated quotation
system upon which the Common Stock is listed and principally traded) over the
five (5) consecutive trading days immediately preceding the date of notice of
conversion of the Series B

Preferred Stock. During 1997, the holders of the Series B Preferred Stock
converted 94 shares of the Series B Preferred Stock into 136,040 shares of
Paradigm's Common Stock. As of December 31, 1997, there were 106 shares of the
Series B Preferred Stock outstanding.
 
  The Series A Preferred Stock and Series B Preferred Stock agreements
contained restrictions on the number of shares of Common Stock that were
issuable on the conversion of the Series A Preferred Stock and Series B
Preferred Stock. Shares of Preferred Stock which were not convertible as a
result of these restrictions were redeemable by Paradigm for cash. On
September 26, 1997 at a Special Meeting of Shareholders, the Stockholders
approved the elimination of the restrictions on the number of shares of Common
Stock issuable on the conversion of the Series A Preferred Stock and Series B
Preferred Stock.
 
  On November 27, 1997, Paradigm sold a total of 100 shares of Series C
Preferred Stock in a private placement at a price of $10,000 per share, for
total proceeds (net of payments to third parties) of approximately $923,000.
The Series C Preferred Stock includes cumulative dividends at 5% per annum.
The Series C Preferred Stock also includes an embedded discount on conversion
which was accreted from the issuance date through January 27, 1998, the date
upon which the Series C Preferred Stock became convertible. The accretion of
the embedded discount and the cumulative dividends have been treated as a
charge to accumulated deficit.
 
  The Series C Preferred Stock is convertible at the option of the holder into
the number of fully paid and non-assessable shares of Common Stock as is
determined by dividing (A) the sum of (1) $10,000 plus (2) the amount of all
accrued but unpaid or accumulated dividends on the shares of Series C
Preferred Stock being converted by (B) the Series C Conversion Price in effect
at the time of conversion. The "Series C Conversion Price" will be equal to
the lower of (i) $5.90 or (ii) eighty-two percent (82%) of the average closing
bid price of a share of Common Stock as quoted on the SCM (or quoted on such
other national or regional securities exchange or automated quotation system
upon which the Common Stock is listed and principally traded) over the five
(5) consecutive trading days immediately preceding the date of notice of
conversion of the Series C Preferred Stock. During 1997, none of the Series C
Preferred Stock was converted into shares of Paradigm's Common Stock.
 
NOTE 8--STOCK COMPENSATION PLANS:
 
  The 1994 Stock Option Plan ("Option Plan") was established on June 21, 1994.
Under the Option Plan, the maximum aggregate number of shares which may be
issued under the Option Plan upon exercise of options is 149,800 shares
(subject to a 3% increase each January 1st). Nonstatutory stock options may be
granted to employees, outside directors and consultants, whereas incentive
stock options can only be granted to employees. Options are generally granted
at fair market value subject to the following:
 
    (a) With respect to options granted to an employee who, at the time of
  the grant owns stock representing more than 10% of the voting power of all
  classes of stock of Paradigm or any parent or subsidiary, the per share
  exercise price shall be no less than 110% of the fair market value on the
  date of the grant for incentive and nonstatutory stock options.
 
    (b) With respect to options granted to any employee other than described
  in the preceding paragraph, the exercise price shall be no less than 100%
  for incentive stock options and 85% for nonstatutory stock options of the
  fair market value on the date of the grant.
 
  The Option Plan separately reserves 15,000 shares of common stock for option
grants to outside directors. Grant of options to Paradigm's outside directors
are made upon appointment to the Board of Directors and in annual increments
thereafter. The exercise price of options granted is the fair market value at
the date of grant.

  In April 1995, the board of directors of Paradigm adopted the Paradigm
Technology, Inc. Employee Stock Purchase Plan (the "ESPP") to provide
employees of Paradigm with an opportunity to purchase common stock through
payroll deductions. The ESPP became effective upon the closing of Paradigm's
initial public offering in July 1995. Under the ESPP, 25,000 shares of common
stock have been reserved for issuance to full-time employees employed with
Paradigm for at least three consecutive months.

  Under the ESPP, the purchase price of the common stock will be equal to 85%
of the lower of (i) the market price of common stock immediately before the
beginning of the applicable participation period or (ii) the market price of
common stock at the time of purchase. In general, each participation period is
24 months long, with a new participation period beginning every six months.
During 1996 and 1997, 7,678 and 2,500 shares were issued under the plan. The
fair value of the employee's purchase rights was estimated using the Black-
Scholes model with the following assumptions for 1995, 1996 and 1997,
respectively; dividend yield of 0% in all years; an expected life of two years
for each purchase period; expected volatility of 48%, 50% and 168%; and risk
free interest rates of 6.2%, 6.3% and 6.2%. The weighted-average fair value of
these purchase rights granted in 1995, 1996 and 1997 was $53.70, $47.80 and
$18.70, respectively.
 
  Had compensation expense for Paradigm's stock-based compensation plans been

  Paradigm's effective tax rate for 1995, 1996 and 1997 was 29%, (3%) and
(0%), respectively. This rate differs from the federal statutory rate due
principally to the following:

  Paradigm has established a valuation allowance equal to its deferred tax
assets on the basis that realization of such assets is not probable.
Management's assessment is based on Paradigm's current net operating losses.
 
  The Tax Reform Act of 1986 limits the use of net operating loss and tax
credit carryforwards in certain situations where changes occur in the stock
ownership of a company. Paradigm experienced ownership changes as a result of
the Reorganization of Paradigm in 1994. As a result of the conversion of
Preferred Stock to Common Stock, Paradigm experienced a change in ownership
subsequent to December 31, 1997. As a result of this change in ownership,
approximately $4 million of net operating losses will be available to Paradigm
through 2012.
 
NOTE 10--CAPITAL LEASE OBLIGATIONS AND COMMITMENTS:
 
  In December 1996, Paradigm entered into an agreement to lease its new
principal administrative facility under an operating lease expiring in 2002.

1997 are as follows (in thousands):

NOTE 11--SALE OF WAFER FABRICATION FACILITY:
 
  Paradigm recorded a loss of $4.6 million in the quarter ended December 31,
1996 as a result of the sale of its wafer fabrication facility. This charge
included the excess of the net book value of leasehold improvements, wafer
fabrication equipment, fabrication work in process inventory and other assets
sold to Orbit Semiconductor, Inc. ("Orbit") over the proceeds received from
Orbit, professional fees, a reserve for an adverse purchase commitment related
to the wafer manufacturing agreement and accruals for other estimated costs.
 
  Orbit paid to Paradigm aggregate consideration of $20 million consisting of
$6.7 million in cash, assumption of $7.5 million of indebtedness associated
with and secured by the Fab, and promissory notes in the principal amounts of
$4.8 million and $1.0 million.
 
  The $4.8 million promissory note was issued in connection with a wafer
supply agreement that required Orbit to supply Paradigm with approximately
9,750 of certain fabricated wafers through May 1997 at $500 per wafer
purchased by Paradigm. In accordance with the terms of the promissory note and
wafer supply agreement, for each wafer purchased from Orbit no cash payment
was required to be made, however, the amount of the promissory note receivable
was reduced by $500 for each wafer purchased. Accordingly, as Paradigm
purchased wafers from Orbit, the outstanding balance of the promissory note
receivable was reduced and inventory was recorded. No balance remained on this
note at December 31, 1997.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
  The $1.0 million promissory note was held in escrow to satisfy certain
representation and warranties made by Paradigm. In July 1997, Paradigm
negotiated an accelerated payment on the $1.0 million promissory note held in
escrow. As part of the agreement, Paradigm allowed Orbit to retain $250,000
for repairs on equipment purchased as part of the Fab sale and certain
additional amounts for other matters, and Paradigm received a net payment of
$750,000 in 1997. No balance remained on this note at December 31, 1997.
 
  In connection with the sale of the Fab, substantially all of the 109
employees associated with the Fab were terminated and became employees of
Orbit. No severance payments were made to employees transferred to Orbit.
 
NOTE 12--LITIGATION:
 
  On August 12, 1996, a securities class action lawsuit was filed in Santa
Clara County Superior Court against Paradigm and certain of its officers and
directors (the "Paradigm Defendants") and PaineWebber, Inc. The class alleged
by plaintiffs consisted of purchasers of Paradigm's Common Stock from November
20, 1995 to March 22, 1996, inclusive (the "Class Period"). The complaint
alleges negligent misrepresentation, fraud and deceit, breach of fiduciary
duty, and violations of certain provisions of the California Corporate
Securities Law and Civil Code. The plaintiffs seek an unspecified amount of
compensatory and punitive damages. Plaintiffs allege, among other things, that
the Paradigm Defendants wrongfully represented that Paradigm would have
protection against adverse market conditions in the semiconductor market based
on Paradigm's focus on high speed, high performance semiconductor products.
The Paradigm Defendants intend to vigorously defend the action. On September
30, 1996, the Paradigm Defendants filed a demurrer seeking to have plaintiffs'
entire complaint dismissed with prejudice. On December 12, 1996, the Court
sustained the demurrer as to all of the causes of action against Michael
Gulett and as to all causes of actions, except for violation of certain
provisions of the California Corporate Securities Law, against the remaining
Paradigm Defendants. The Court, however, granted plaintiffs leave to amend the
complaint to attempt to cure the defects which caused the Court to sustain the
demurrer. Plaintiffs failed to amend within the allotted time. On January 8,
1997, the Paradigm Defendants filed an answer to the complaint denying any
liability for the acts and damages alleged by the plaintiffs. Plaintiffs have
since served the Paradigm Defendants with discovery requests for production of
documents and interrogatories, to which the Paradigm Defendants have
responded. Plaintiffs have also subpoenaed documents from various third
parties. The Paradigm Defendants have served the plaintiffs with an initial
set of discovery requests, to which plaintiffs have responded. The Paradigm
Defendants also took the depositions of the named plaintiffs on April 9, 1997.
On January 15, 1997, plaintiffs filed a motion to certify the matter as a
class action. Plaintiffs sought by their motion to certify a nationwide class
of those who purchased Paradigm's stock during the Class Period. After several
hearings and continuances, on February 9, 1998 the Court certified a class
consisting only of California purchasers of Paradigm's stock during the Class
Period. Plaintiffs have set a hearing date of April 9, 1998 for a motion to
amend their complaint to incorporate factual allegations derived from the
February 21, 1997 action described below. There can be no assurance that
Paradigm will be successful in the defense of this action. Even if Paradigm is
successful in such defense, it may incur substantial legal fees and other
expenses related to this claim. If unsuccessful in the defense of any such
claim, Paradigm's business, operating results and cash flows could be
materially adversely affected.
 
  On February 21, 1997, an additional purported class action lawsuit was filed
in Santa Clara County Superior Court against Paradigm and certain of its
officers and directors, with causes of action and factual allegations
essentially identical to those of the August 12, 1996 class action lawsuit.
This second class action is asserted against the same Paradigm Defendants,
PaineWebber, Inc. and Smith Barney. Prior to the hearing on the Paradigm
Defendants' demurrer to the initial complaint, plaintiff amended his complaint
to incorporate factual allegations derived from the May 19, 1997 lawsuit
described below. The Paradigm Defendants filed a demurrer to the amended
complaint, which was heard on September 9, 1997. On September 10, 1997, the
Court issued an order sustaining the Paradigm Defendants' demurrer as to all
causes of action without leave to amend. A judgment in favor of the Paradigm
Defendants dismissing the entire complaint was entered by the Court on

September 23, 1997. Plaintiffs have appealed the decision and filed a brief in
support of its appeal. The Paradigm Defendants' responsive brief is due to be
filed March 30, 1998. There can be no assurances that Paradigm will be
successful in defeating the appeal. Even if Paradigm is successful in
defeating the appeal, it may incur substantial legal fees and other expenses
related to this appeal. If unsuccessful in defeating the appeal, Paradigm's
business operating results and cash flows could be materially adversely
affected.
 
  On May 19, 1997, several former employees of Paradigm filed an action in
Santa Clara County Superior Court. The complaint names as defendants Paradigm,
Michael Gulett, Richard Veldhouse, Dennis McDonald and Chiang Lam. Plaintiffs
filed with the complaint a notice that they consider their case related
legally and factually to the August 12, 1996 class action lawsuit described
above. The Complaint alleges fraud, breach of fiduciary duty and violations of
certain provisions of the California Corporate Securities Law and Civil Code.
Plaintiffs allege that they purchased Paradigm's stock at allegedly inflated
prices and were damaged thereby. The plaintiffs seek an unspecified amount of
compensatory, rescissory and/or punitive damages. Defendants responded to the
complaint on September 12, 1997 by filing a demurrer as to all causes of
action. Prior to the hearing on the demurrer, Plaintiffs amended their
complaint to identify two allegedly fraudulent sale transactions. On February
20, 1998, defendants filed a demurrer as to all causes of action in the
amended complaint, which is set to be heard April 2, 1998. Plaintiffs have
served Paradigm and two of the individual defendants with requests for
production of documents, to which Paradigm and the individual defendants have
responded. Paradigm has served plaintiff with form interrogatories, to which
they have responded. There can be no assurance that Paradigm will be
successful in such defense. Even if Paradigm is successful in such defense, it
may incur substantial legal fees and other expenses related to this claim. If
unsuccessful in the defense of any such claim, Paradigm's business, operating
results and cash flows could be materially adversely affected.
 
  Paradigm is involved in various other litigation and potential claims which
management believes, based on facts presently known, will not have a material
adverse effect on the results of operations or the financial position of
Paradigm.

  On March 6, 1998, Paradigm entered into a definitive merger agreement
providing for the acquisition of all of the outstanding capital stock of IXYS
Corporation ("IXYS") in exchange for Common Stock of Paradigm. The exchange
ratio in the Merger for the IXYS equity securities will be the greater of two
ratios. The first ratio provides that upon the Merger the holders of equity
securities of IXYS hold 95% of the fully diluted capitalization of the
combined company and that the holders of equity securities of Paradigm will
hold 5% of the fully diluted capitalization of the combined company. (As used
herein, fully diluted capitalization means the sum of the number of shares of
common stock outstanding and issuable upon exercise or conversion of all
outstanding preferred stock, warrants, options and other rights.) The second
ratio provides that the value associated with the fully diluted capitalization
of IXYS, at the time of the consummation of the Merger, be at least $150
million, based upon an average of the closing prices of Paradigm's Common
Stock prior to Paradigm's stockholders meeting. Consummation of the merger
requires the approval of Paradigm's and IXYS' stockholders and various
regulatory approvals. If approved, the transaction is anticipated to be
accounted for as a purchase of Paradigm by IXYS for financial reporting
purposes.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
NOTE 1: BASIS OF PRESENTATION
 
  The unaudited condensed financial statements have been prepared by Paradigm
Technology, Inc. ("Paradigm" or the "Company"), pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information and
footnote disclosures, normally included in financial statements prepared in
accordance with generally accepted accounting principles, have been condensed
or omitted pursuant to such rules and regulations.
 
  In the opinion of management, the unaudited interim condensed financial
statements included herein have been prepared on the same basis as the
December 31, 1997 audited financial statements, contained in the Company's
annual report on Form 10-K filed on March 24, 1998 and include all
adjustments, consisting of only normal recurring adjustments, necessary to
fairly state the information set forth therein. Results for the three month
period ended March 29, 1998 are not necessarily indicative of the results to
be expected for the entire year.
 
  The preparation of the interim condensed financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that effect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities as of the date
of the interim condensed consolidated financial statements and the reported
amounts of revenue and expenses during the report period. Actual results could
differ from estimates.
 
  The Company markets high speed high density Static Random Access Memory
("SRAM") products for uses in telecommunication devices, workstations and high
performance personal computers to Original Equipment Manufacturers and
distributors in the United States, Europe and the Far East.
 
  The SRAM business is highly cyclical and has been subject to significant
downturns at various times that have been characterized by diminished product
demand, production overcapacity, and accelerated erosion of average selling
prices. During the latter part of 1995 continuing into 1996, 1997 and the
first three months of 1998, the market for certain SRAM devices experienced an
excess supply relative to demand which resulted in a significant downward
trend in prices.
 
  The selling prices that the Company is able to command for its products are
highly dependent on industry-wide production capacity and demand. In this
regard, the Company did experience rapid erosion in product pricing in 1996,
1997 and during the first three months of 1998 which was not within the
control of the Company. The Company could continue to experience a downward
trend in pricing which could adversely affect the Company's operating results.
 
  The Company's recent operations have consumed substantial amounts of cash.
During 1997, the Company completed the private placement of Series A Preferred
Stock, Series B Preferred Stock, and Series C Preferred Stock for aggregate
net proceeds of approximately $4,673,000. The Company believes that it will
require additional cash infusion from similar private placements of equity or
other sources of liquidity, such as asset sales and equipment financing to
meet the Company's projected working capital and other cash requirements. The
sale of additional equity or other securities could result in additional
dilution to the Company's stockholders. There can be no assurance that such
additional financing, if required, can be obtained on acceptable terms, if at
all.
 
  As a result of these circumstances, the Company's independent accountants'
opinion on the Company's December 31, 1997 financial statements includes an
explanatory paragraph indicating that these matters raise a substantial doubt
about the Company's ability to continue as a going concern.

             NOTES TO CONDENSED FINANCIAL STATEMENTS--(CONTINUED)
                                  (UNAUDITED)
 
 
  On March 6, 1998, the Company entered into a definitive merger agreement
providing for the acquisition of all of the outstanding capital stock of IXYS
Corporation ("IXYS") in exchange for Common Stock of the Company. The exchange
ratio in the Merger for the IXYS equity securities will be the greater of two
ratios. The first ratio provides that upon the Merger the holders of equity
securities of IXYS hold 95% of the fully diluted capitalization of the
combined company and that the holders of equity securities of the Company will
hold 5% of the fully diluted capitalization of the combined company. (As used
herein, fully diluted capitalization means the sum of the number of shares of
common stock outstanding and issuable upon exercise or conversion of all
outstanding preferred stock, warrants, options and other rights.) The second
ratio provides that the value associated with the fully diluted capitalization
of IXYS, at the time of the consummation of the Merger, be at least $150
million, based upon an average of the closing prices of the Company's Common
Stock prior to the Company's stockholders meeting. Consummation of the merger
requires the approval of the Company's and IXYS' stockholders and various
regulatory agency approvals. If approved, the transaction is anticipated to be
accounted for as a purchase of the Company by IXYS for financial reporting
purposes.
 
  This report on Form 10-Q for the quarter ended March 29, 1998 should be read
in conjunction with the audited financial statements as of December 31, 1997,
and the notes thereto included in the Company's Annual Report on Form 10-K
filed on March 24, 1998.
 
NOTE 2: REVERSE STOCK SPLIT
 
  On May 1, 1998, the Company's stockholders approved a 10-for-1 reverse stock
split of the Company's common stock, such that every 10 shares shall be
combined into one share of common stock. All prior period common shares and
per share data in these condensed financial statements have been restated to
reflect this stock split.
 
NOTE 3: NET INCOME (LOSS) PER SHARE
 
  During the quarter ended December 31, 1997, the Company adopted Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128").
SFAS 128 requires presentation of both Basic EPS and Diluted EPS. Basic EPS is
computed by dividing net income available to common stockholders (numerator)
by the weighted average number of common shares outstanding (denominator)
during the period. Diluted EPS gives effect to all dilutive potential common
shares outstanding during a period. In computing Diluted EPS, the average
price for the period is used in determining the number of shares assumed to be
purchased from exercise of stock options, warrants and Convertible Preferred
Stock. Net income (loss) per share for all prior periods presented has been
restated to conform to the provisions of SFAS 128.

NOTE 5: LITIGATION
 
  On August 12, 1996, a securities class action lawsuit was filed in Santa
Clara County Superior Court against the Company and certain of its officers
and directors (the "Paradigm Defendants") and PaineWebber, Inc. The class
alleged by plaintiffs consisted of purchasers of the Company's Common Stock
from November 20, 1995 to March 22, 1996, inclusive (the "Class Period"). The
complaint alleged negligent misrepresentation, fraud and deceit, breach of
fiduciary duty and violations of certain provisions of the California
Corporate Securities Law and Civil Code. The plaintiffs seek an unspecified
amount of compensatory and punitive damages. Plaintiffs allege, among other
things, that the Paradigm Defendants wrongfully represented that the Company
would have protection against adverse market conditions in the semiconductor
market based on the Company's focus on high speed, high performance
semiconductor products. The Paradigm Defendants intend to vigorously defend
the action. On September 30, 1996, the Paradigm Defendants filed a demurrer
seeking to have plaintiffs' entire complaint dismissed with prejudice. On
December 12, 1996, the Court sustained the demurrer as to all of the causes of
action against Michael Gulett and as to all causes of actions, except for
violation of certain provisions of the California Corporate Securities Law,
against the remaining Paradigm Defendants. The Court, however, granted
plaintiffs leave to amend the complaint to attempt to cure the defects which
caused the Court to sustain the demurrer. Plaintiffs failed to amend within
the allotted time. On January 8, 1997, the Paradigm Defendants filed an answer
to the complaint denying any liability for the acts and damages alleged by the
plaintiffs. Plaintiffs have since served the Paradigm Defendants with
discovery requests for production of documents and interrogatories, to which
the Paradigm Defendants have responded. Plaintiffs have also subpoenaed
documents from various third parties. The Paradigm Defendants have served the
plaintiffs with an initial set of discovery requests, to which Plaintiffs have
responded. The Paradigm Defendants also took the depositions of the named
plaintiffs on April 9, 1997. On January 15, 1997, plaintiffs filed a motion to
certify the matter as a class action. Plaintiffs sought by their motion to
certify a nationwide class of those who purchased the Company's stock during
the Class Period. After several hearings and continuances, on February 9, 1998
the Court certified a class consisting only of California purchasers of the
Company's stock during the Class Period. On April 9, 1998, the Court granted
plaintiff's motion to amend their complaint to incorporate factual allegations
derived from the May 19, 1997 action described below. There can be no
assurance that the Company will be successful in the defense of this action.
Even if Paradigm is successful in such defense, it may incur substantial legal
fees and other expenses related to this claim. If unsuccessful in the defense
of any such claim, the Company's business, operating results and cash flows
could be materially adversely affected.
 
  On February 21, 1997, an additional purported class action lawsuit was filed
in Santa Clara County Superior Court against the Company and certain of its
officers and directors, with causes of action and factual allegations
essentially identical to those of the August 12, 1996 class action lawsuit.
This second class action is asserted against the same Paradigm Defendants,
PaineWebber, Inc. and Smith Barney. Prior to the hearing on the Paradigm
Defendants' demurrer to the initial complaint, Plaintiff amended his complaint
to incorporate factual allegations derived from the May 19, 1997 lawsuit
described below. The Paradigm Defendants filed a demurrer to the amended
complaint, which was heard on September 9, 1997. On September 10, 1997, the
Court issued an order sustaining the Paradigm Defendants' demurrer as to all
causes of action without leave to amend. A judgment in favor of the Paradigm
Defendants dismissing the entire complaint was entered by the Court on
September 23, 1997. Plaintiff has appealed the decision and filed a brief in
support of his appeal. The Paradigm Defendants' responsive brief was filed on
March 30, 1998. There can be no assurances that the Company will be successful
in defeating the appeal. Even if Paradigm is successful in defeating the
appeal, it may incur substantial legal fees and other expenses related to this
appeal. If unsuccessful in defeating the appeal, the Company's business,
operating results and cash flows could be materially adversely affected.
 
  On May 19, 1997, three former employees of the Company filed an action in
Santa Clara County Superior Court. The complaint names as defendants the
Company, Michael Gulett, Richard Veldhouse, Dennis McDonald

and Chiang Lam. Plaintiffs filed with the complaint a notice that they
consider their case related legally and factually to the August 12, 1996 class
action lawsuit described above. The Complaint alleges fraud, breach of
fiduciary duty and violations of certain provisions of the California
Corporate Securities Law and Civil Code. Plaintiffs allege that they purchased
the Company's stock at allegedly inflated prices and were damaged thereby. The
plaintiffs seek an unspecified amount of compensatory, rescissory and/or
punitive damages. Defendants responded to the complaint on September 12, 1997
by filing a demurrer as to all causes of action. Prior to the hearing on the
demurrer, Plaintiffs amended their complaint to identify two allegedly
fraudulent sale transactions. Defendants filed a demurrer as to all causes of
action in the amended complaint, which was heard on April 2, 1998. That same
day, the Court issued its order sustaining the demurrer on multiple grounds,
but granted plaintiffs leave to amend the complaint by May 15, 1998.
Plaintiffs have served the Company and two of the individual defendants with
requests for production of documents, to which the Company and the individual
defendants have responded. Plaintiffs also took the deposition of a third
party on April 23, 1998. The Company has served plaintiffs with form
interrogatories and requests for production of documents, to which they have
responded. The Company also took plaintiffs' depositions on April 20-22, 1998.
The deposition of one of the plaintiffs is continuing. There can be no
assurance that the Company will be successful in the defense of this action.
Even if Paradigm is successful in such defense, it may incur substantial legal
fees and other expenses related to this claim. If unsuccessful in the defense
of any such claim, the Company's business, operating results and cash flows
could be materially adversely affected.
 
  The Company is involved in various other litigation and potential claims.
Due to the inherent uncertainty of litigation, management is not able to
reasonably estimate losses that may be incurred in relation to this
litigation. However, based on the facts presently known, management believes
that the resolution of these matters will not have a material adverse impact
on the results of operations or the financial position of the Company.

NOTE 7: OPTION REPRICING
 
  In March 1998, the Company's Board agreed that in order to provide
incentives to its employees and directors, repricing of outstanding options
was needed to align the option exercise price more closely with the fair
market value of the underlying Common Stock as determined by the marketplace.
Therefore, the Company implemented a program whereby option holders could
exchange higher priced option shares for the same number of lower priced
option shares. The new options were issued on March 6, 1998 at $3.187 per
share, which is 85% of the fair market value of $3.75. Executive officers must
remain active on the Company's payroll to exercise their new options. All
executive officers and directors holding options were eligible to participate
in this program. A total of approximately 118,000 shares were repriced which
will result in compensation expense aggregating $67,000, which will be
recorded over the remaining vesting period of the repriced options.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
IXYS Corporation and Subsidiary
 
  We have audited the accompanying consolidated balance sheets of IXYS
Corporation and Subsidiary as of March 31, 1997 and 1998, and the related
consolidated statements of income, stockholders' deficit and cash flows for
each of the three years in the period ended March 31, 1998. These financial
statements are the responsibility of IXYS' management. Our responsibility is
to express an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of IXYS
Corporation and Subsidiary as of March 31, 1997 and 1998, and the consolidated
results of their operations and their cash flows for each of the three years
in the period ended March 31, 1998, in conformity with generally accepted
accounting principles.

                               IXYS CORPORATION
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. FORMATION AND BUSINESS OF IXYS:
 
  IXYS Corporation designs, develops and markets power semiconductors used
primarily in controlling energy in motor drives, power conversion (including
uninterruptible power supplies (UPS) and switch mode power supplies (SMPS))
and medical electronics. IXYS' power semiconductors convert electricity at
relatively high voltage and current levels to create efficient power as
required by a specific application. IXYS' target market includes segments of
the power semiconductor market that require medium to high power
semiconductors, with a particular emphasis on higher power semiconductors.
IXYS sells power semiconductors, including power MOSFETs, insulated gate
bipolar transistors (IGBTs), thyristors (silicon controlled rectifiers
or"SCRs") and rectifiers, including fast recovery epitaxial diodes (FREDs).
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
 Principles of Consolidation:
 
  The consolidated financial statements include the accounts of IXYS and its
wholly-owned subsidiary, IXYS Semiconductor GmbH (IXYS GmbH). All material
intercompany accounts and transactions have been eliminated.
 
 Use of Estimates:
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could materially differ from IXYS' estimates.
 
 Foreign Currency Translation:
 
  The local currency is considered to be the functional currency of the
operations of IXYS GmbH. Accordingly, assets and liabilities are translated at
the exchange rate in effect at year-end and revenues and expenses are
translated at average rates during the year. Adjustments resulting from the
translation of the accounts of IXYS GmbH into U.S. dollars are included in
cumulative translation adjustment, a separate component of stockholders'
deficit. Foreign currency transaction gains and losses are included as a
component of other income and expense.
 
 Cash Equivalents:
 
  IXYS considers all highly liquid investments with original or remaining
maturities of three months or less at the time of purchase to be cash
equivalents.
 
 Inventories:
 
  Inventories, consisting primarily of bipolar devices, transistors, diodes
and integrated circuits, are stated at the lower of cost or market. Cost is
determined on a standard cost basis which approximates actual costs determined
on a first-in, first-out (FIFO) method.
 
 Plant and Equipment:
 
  Plant and equipment, including equipment under capital leases, is stated at
cost less accumulated depreciation and amortization. Depreciation or
amortization is computed using the straight-line method over estimated useful
lives of three to five years for equipment and twenty years for buildings.
Upon disposal, the

                               IXYS CORPORATION
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
assets and related accumulated depreciation are removed from IXYS' accounts
and the resulting gains or losses are reflected in the statements of income.
The Company's policy is to regularly review the carrying value of specialized
assets to evaluate the remaining life and recoverability of such equipment in
light of current market conditions.
 
 Product Warranty:
 
  Expected future product warranty expense is recorded when the product is
sold.
 
 Revenue Recognition:
 
  Revenue from product sales is recognized upon shipment and is reflected net
of an allowance for estimated returns and discounts.
 
 Advertising:
 
  IXYS expenses advertising as the costs are incurred. Advertising expense for
the years ended March 31, 1996, 1997 and 1998 was $288,000, $268,000 and
$408,000, respectively.
 
 Research and Development:
 
  Research and development costs are charged to operations as incurred.
 
 Income Taxes:
 
  IXYS accounts for income taxes under the liability method whereby deferred
tax assets and liabilities are determined based on differences between
financial reporting and tax bases of assets and liabilities and are measured
using the enacted tax rates and laws that will be in effect when the
differences are expected to reverse.
 
 Net Income Per Share:
 
  IXYS has adopted Statement of Financial Accounting Standards No. 128 (SFAS
128), "Earnings per Share," which is effective for all periods ending after
December 15, 1997. SFAS 128 requires dual presentation of basic and diluted
earnings per share (EPS) for complex capital structures on the face of the
Statement of Income. Basic EPS is computed by dividing net income by the
weighted-average number of common shares outstanding for the period. Diluted
EPS reflects the potential dilution from the exercise or conversion of other
securities into common stock.
 
 Recent Accounting Pronouncements:
 
  In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130 (SFAS 130), "Reporting Comprehensive
Income." This statement establishes requirements for disclosure of
comprehensive income and becomes effective for IXYS for fiscal year 1999, with
reclassification of earlier financial statements for comparative purposes.
Comprehensive income generally represents all changes in stockholders' equity
except those resulting from investments or contributions by stockholders. IXYS
is evaluating alternative formats for presenting this information, but does
not expect this pronouncement to materially impact IXYS' results of
operations.
 
  In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131 (SFAS 131), "Disclosures about Segments
of an Enterprise and Related Information". This statement establishes
standards for disclosure about operating segments in annual financial
statements and

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
selected information in interim financial reports. It also establishes
standards for related disclosures about products and services, geographic
areas and major customers. This statement supersedes Statement of Financial
Accounting Standards No. 14, "Financial Reporting for Segments of a Business
Enterprise." The new standard becomes effective for the Company's fiscal year
1999, and requires that comparative information from earlier years be restated
to conform to the requirements of this standard. IXYS is evaluating the
requirements of SFAS 131 and the effects, if any, on IXYS' current reporting
and disclosures.
 
 Business Risks:
 
  IXYS manufactures approximately 70% of its wafers, an integral component of
its products, in its wholly owned facility in Germany. IXYS purchases the
remaining 30% of its wafers from two other suppliers. There can be no
assurance that material disruptions in supply will not occur in the future. In
such event, IXYS may have to identify and secure additional foundry capacity
and may be unable to identify or secure additional foundry capacity from
another manufacturer, particularly at the levels that IXYS currently
anticipates such foundries to provide. Even if such capacity is available from
another manufacturer, the qualification process could take six months or
longer. If IXYS were unable to qualify alternative manufacturing sources for
existing or new products in a timely manner or if such sources were unable to
produce semiconductor devices with acceptable manufacturing yields and at
acceptable prices, IXYS' business, financial condition and results of
operations would be materially and adversely affected.
 
   Included in IXYS' consolidated balance sheet at March 31, 1998 are the net
assets, at book value, of IXYS' manufacturing operation in Germany, which
total approximately $5.7 million.
 
 Concentration of Credit Risk:
 
  IXYS invests its excess cash primarily in short-term time deposit accounts
with a major German bank and money market accounts with a U.S. bank. These
securities typically mature within ninety days and bear minimal credit risk.
IXYS has not experienced any losses on such investments.
 
  IXYS sells its products primarily to distributors and original equipment
manufacturers in the United States and in Europe. IXYS performs ongoing credit
evaluations of its customers and generally does not require collateral. An
allowance for potential credit losses is maintained by IXYS and such losses
have not been material.
 
 Fair Value of Financial Instruments:
 
  Carrying amounts of certain of IXYS' financial instruments including cash
and cash equivalents, accounts receivable, other assets, accounts payable and
other accrued liabilities approximate fair value due to their short
maturities. Based on borrowing rates currently available to IXYS for loans
with similar terms, the carrying value of notes payable to bank and notes
receivable from shareholders approximate fair value.

  Note payable to bank at March 31, 1997 consists of a $2,500,000 loan from a
U.S. bank which was due in January 1998. IXYS repaid the loan at its scheduled
maturity date.
 
  In December 1997, IXYS entered into a loan and security agreement with a
U.S. bank to borrow up to an aggregate amount not to exceed $5 million. The
loan bears interest at the bank's prime rate (8.50% at March 31, 1998),
payable monthly, and matures in August 1999. The loan is collateralized by
certain assets and contains certain general and financial covenants, including
a requirement that IXYS remain solvent and able to pay its debts as they
become due. At March 31, 1998, IXYS has drawn $2,100,000 against the loan.
IXYS was in violation of a financial ratio covenant during the period from
January 1, 1998 through March 31, 1998 and, subsequent to year end, received a
waiver of the default from the bank through August 31, 1998. However, as it is
probable that the condition leading to the default will not be corrected prior
to August 31, 1998, IXYS has reclassified the entire amount outstanding at
March 31, 1998 as current.
 
  In February 1997, the Company entered into a loan agreement with a German
bank to finance the acquisition of the Lampertheim facility (the "Facility")
from Asea Brown Boveri Aktiengesellschaft (ABB), a stockholder. The loan was
for the total amount of DM 13,250,000 ($7,175,000 at March 31, 1998), payable
in monthly installments of DM 125,226 ($67,800 at March 31, 1998) and is due
no later than October 31, 2009. The loan, which is collateralized by the
Facility, bears interest at the annual rate of 5.40% through August 2001, at
which time the interest rate will be adjusted to market rates in accordance
with the terms of the loan agreement. The acquisition of the Facility closed
in January 1998, at which time the proceeds were drawn against the loan. At
March 31, 1998, the amount outstanding under the loan agreement was DM
13,050,000 ($7,068,000).
 
  IXYS leases certain equipment under capital lease arrangements expiring
through fiscal 2001 at interest rates of 4.9% to 6.3%.
 
  Future minimum payments under capital lease obligations and notes payable

  Rent expense, including rent expense to ABB for IXYS' main manufacturing
facility, for fiscal years ended March 31, 1996, 1997 and 1998 amounted to
$594,000, $410,000 and $571,000, respectively.
 
  At March 31, 1997, IXYS had outstanding Discounted Acceptances totaling
$617,018 with a financial institution. The Discounted Acceptances were issued
in support of obligations to a vendor for inventory receipts prior to March
31, 1997. IXYS also had outstanding letters of credit totaling $139,000 with a
financial institution which were issued in support of inventory to be received
subsequent to March 31, 1997. At March 31, 1998, IXYS had no outstanding
Discounted Acceptances or letters of credit. As of March 31, 1997 and 1998,
IXYS had cash deposits with a financial institution of $1,591,000 and
$950,000, respectively, which were restricted as to use and represent
compensating balances for current or future Discounted Acceptances and letters
of credit.
 
 Contingencies:
 
  In February 1997, in U.S. District Court, a judgment was entered against
IXYS for $3.65 million related to the sale of products that infringed certain
patents. IXYS paid $3.13 million of the $3.65 million judgment in 1997 and
filed an appeal in U.S. Federal Court. Through the appeal process, IXYS
accrued the unpaid portion of the judgment and was accruing royalty expense in
accordance with the Court's judgment. At March 31, 1997, IXYS was holding
approximately $575,000 in an escrow account for payment of the balance of the
judgment.
 
  In December 1997, IXYS entered into a settlement agreement with the
plaintiff, whereby there would be no liability to IXYS. The agreement is
subject to ratification by the U.S. District Court, and during 1998, the
plaintiff returned the $3.13 million payment plus interest which is included
in other income on the consolidated statements of income.

  Each share of Series A and B preferred stock is convertible into common
stock on a one-for-one basis, respectively, subject to adjustment for certain
changes in common stock.
 
  Conversion of the Series A and B preferred stock is at the preferred
stockholder's option, except that conversion is automatic on the closing of a
public offering of IXYS' common stock which meets certain net proceeds and
per-share amounts. IXYS shall reserve and keep available out of its authorized
but unissued common stock such number of shares of common stock as shall from
time to time be sufficient to effect conversion of Series A and B preferred
stock.
 
  The holders of Series A and B preferred stock may receive noncumulative
dividends when and as declared by the Board of Directors at the rate of $.0177
and $.0096, respectively, per annum in preference to holders of common stock.
As of March 31, 1998, no dividends have been declared or are payable. The
holders of preferred stock have certain registration rights.
 
  Holders of Series A and B preferred stock are entitled to the number of
votes equal to the number of shares of common stock into which the preferred
shares are convertible and have the right of first refusal to purchase, pro
rata, all or any part of new securities (as defined) which may be offered for
sale by IXYS.
 
  On December 31, 1998 and on each December 31st thereafter, IXYS has the
obligation to redeem one-fourth of the Series A and B preferred stock at a
total price of $.739 and $.138 per share, respectively, plus any unpaid
dividends, if declared. $9,300,000 has been reclassified as the current
portion of the mandatorily redeemable preferred stock.
 
  In the event of liquidation of IXYS, holders of Series A and B preferred

 Stock Purchase and Incentive Stock Option Plans:
 
  IXYS has a 1989 Stock Option Plan (the Plan) under which incentive stock
options may be granted to key employees at prices not less than fair market
value at the time of grant, while supplemental stock options may be granted to
key employees, directors and consultants at prices not less than 85% of fair
market value at the time of grant. The options once granted expire ten years
from the date of grant. The Board of Directors has the full power to determine
the provisions of each option issued under both plans.

  In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standard No. 123 (SFAS 123), "Accounting for Stock-
Based Compensation," which was effective for IXYS' fiscal year 1997. SFAS 123
allows companies to either account for stock-based compensation under the new
provisions of SFAS 123 or under the provisions of Accounting Principles Board
Opinion No. 25 (APB 25), "Accounting for Stock Issued to Employees," but
requires pro forma disclosure in the footnotes to the financial statements as
if the measurement provisions of SFAS 123 had been adopted.

  IXYS has continued to account for its stock based compensation under the
Plan in accordance with APB 25. Accordingly, no compensation expense has been
recognized for stock options granted under the Plan. Had compensation cost for
the Plan been determined based on the fair value at the grant date for awards
in fiscal years 1996, 1997 and 1998 consistent with the provisions of SFAS No.
123, IXYS' net income and net income per share for fiscal years 1996, 1997 and
1998 would have decreased to the pro forma amounts indicated below (in

  In future years, annual compensation expense will vary relative to the
vesting of options granted in those future years.
 
  In accordance with the provisions of SFAS 123, the fair value of each option
is estimated using the minimum value method allowable for non-public companies
and using the following assumptions used for grants during the years ended
March 31, 1996 and 1997; dividend yield of 0%, volatility of 0%, risk-free
interest rates of between 5.23% to 6.67% at the date of grant and an expected
term of four years. The weighted-average fair value of options granted during
1996 and 1997 was $0.078 and $0.094 per share, respectively. There were no
stock options granted in fiscal year 1998.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
  Federal net operating loss carryforwards of approximately $7,400,000 expire
in the years 1999 through 2010. Federal research and development credits of
approximately $500,000 expire in the years 1999 through 2009.
 
  Based on its recent history of profitability, IXYS considers it more likely
than not that it will realize the benefit from its net deferred tax assets.
The amount of the deferred tax asset considered realizable could be reduced if
estimates of future taxable income declines significantly. The future
utilization of IXYS' net operating loss carryforwards may be subject to
limitation as a result of any future changes in ownership.
 
13. FOREIGN OPERATIONS:
 
  IXYS' foreign operations consist of those of its subsidiary IXYS GmbH in

15. ACQUISITION AND MERGER:
 
  In March 1998, IXYS signed a definitive agreement to acquire and merge with
Paradigm Technologies, Inc. (Paradigm), a company that designs and markets
fast SRAM products. The acquisition will be structured as a reverse merger
where Paradigm will issue shares to all IXYS stockholders in exchange for IXYS
shares. At the conclusion of the merger, IXYS stockholders will hold
approximately 98% of the Combined Company. For financial accounting purposes,
IXYS will be the surviving company and the historic financial information will
be that of IXYS.

                              AGREEMENT AND PLAN
                         OF MERGER AND REORGANIZATION
 
  This Agreement And Plan Of Merger And Reorganization (this "Agreement") is
made and entered into as of March 6, 1998 by and among: Paradigm Technology,
Inc., a Delaware corporation ("Parent"); Paradigm Enterprises, Inc., a
Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub");
and Ixys Corporation, a Delaware corporation (the "Company"). Certain
capitalized terms used in this Agreement but not defined herein are defined in
Exhibit A.
 
                                   RECITALS
 
  A. Parent, Merger Sub and the Company intend to effect a merger of Merger
Sub with and into the Company in accordance with this Agreement and the
Delaware General Corporation Law (the "Merger"). Upon consummation of the
Merger, Merger Sub will cease to exist, and the Company will become a wholly
owned subsidiary of Parent.
 
  B. It is intended that the Merger qualify as a tax free reorganization
within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"). For financial reporting purposes, it is intended that
the Merger be accounted for as a "purchase."
 
  C. The respective boards of directors of Parent, Merger Sub and the Company
have approved this Agreement and the Merger.
 
                                   AGREEMENT
 
  The parties to this Agreement, intending to be legally bound, agree as
follows:
 
SECTION 1. DESCRIPTION OF TRANSACTION
 
  1.1 MERGER OF MERGER SUB INTO THE COMPANY. Upon the terms and subject to the
conditions set forth in this Agreement, at the Effective Time (as defined in
Section 1.3), Merger Sub shall be merged with and into the Company, and the
separate existence of Merger Sub shall cease. The Company will continue as the
surviving corporation in the Merger (the "Surviving Corporation").
 
  1.2 EFFECT OF THE MERGER. The Merger shall have the effects set forth in
this Agreement and in the applicable provisions of the Delaware General
Corporation Law (the "DGCL").
 
  1.3 CLOSING; EFFECTIVE TIME. The consummation of the transactions
contemplated by this Agreement (the "Closing") shall take place at the offices
of Cooley Godward LLP, Five Palo Alto Square, 3000 El Camino Real, Palo Alto,
California, at 10:00 a.m. on a date to be agreed upon by Parent and the
Company (the "Closing Date"), which (subject to the satisfaction or waiver of
the conditions set forth in Sections 7 and 8) shall be no later than the fifth
business day after satisfaction of the latest to occur of the conditions set
forth in Sections 7.4, 7.5, 7.7, 8.4, 8.5 and 8.12. Contemporaneously with or
as promptly as practicable after the Closing, the parties shall cause a
properly executed certificate of merger conforming to the requirements of the
DGCL (the "Certificate of Merger") to be filed with the Secretary of State of
the State of Delaware. The Merger shall take effect at the time the
Certificate of Merger is filed with the Secretary of State of the State of
Delaware (the "Effective Time").
 
  1.4 CERTIFICATE OF INCORPORATION AND BYLAWS; DIRECTORS AND OFFICERS. Unless
otherwise determined by the Company prior to the Effective Time:
 
    (a) the Certificate of Incorporation of the Surviving Corporation shall
  be amended and restated as of the Effective Time to conform to Exhibit B;
 
                                      A-1
<PAGE>
 
    (b) the Bylaws of the Surviving Corporation shall be amended and restated
  as of the Effective Time to conform to the Bylaws of the Company; and
 
    (c) the directors and officers of the Surviving Corporation immediately
  after the Effective Time shall be the respective individuals set forth on
  Exhibit C.
 
  1.5 CONVERSION OF SHARES.
 
  (a) Subject to Sections 1.5(d) and 1.8, at the Effective Time, by virtue of
the Merger and without any further action on the part of Parent, Merger Sub,
the Company or any stockholder of the Company:
 
    (i) any shares of Company Capital Stock then held by the Company or any
  subsidiary of the Company (or held in the Company's treasury) shall be
  canceled and retired and shall cease to exist, and no consideration shall
  be delivered in exchange therefor;
 
    (ii) any shares of Company Capital Stock then held by Parent or Merger
  Sub, or any other subsidiary of Parent, shall be canceled and retired and
  shall cease to exist, and no consideration shall be delivered in exchange
  therefor;
 
    (iii) except as provided in clauses "(i)" and "(ii)" above and subject to
  Sections 1.5(b)(iv), 1.5(d), and 1.8 each share of Company Common Stock
  then outstanding shall be converted into the right to receive a fraction of
  a share of Parent Common Stock equal to the Exchange Ratio;
 
    (iv) except as provided in clauses "(i)" and "(ii)" above and subject to
  Sections 1.5(b)(iv), 1.5(d), and 1.8 each share of Company Preferred Stock
  then outstanding shall be converted into the right to receive a fraction of
  a share of Parent Common Stock equal to the Exchange Ratio; and
 
    (v) each share of the common stock, par value $0.001 per share, of Merger
  Sub then outstanding shall be converted into one share of common stock of
  the Surviving Corporation.
 
  (b) The "Exchange Ratio" shall be the greater of (A) the Percentage Formula
Ratio or (B) the Valuation Formula Ratio. The Exchange Ratio shall be
expressed to six digits to the right of the decimal place.
 
    (i) As used herein, the "Percentage Formula Ratio" shall be determined
  according to the following formula:
 
                                    19 x B
                                     -----
                                 A =
                                       C
 
  , where "A" is the Percentage Formula Ratio, expressed to six digits to the
  right of the decimal place, "B" is the fully diluted capitalization of
  Parent, immediately prior to the Effective Time and having given effect to
  the Reverse Stock Split, expressed as the sum of (x) the number of shares
  of Parent Common Stock outstanding, (y) the number of shares of Parent
  Common Stock into which the outstanding Parent Preferred Stock converts
  pursuant to the Parent Preferred Stock Conversion and (z) the aggregate
  number of shares of Parent Common Stock for which outstanding warrants,
  options or other rights to acquire Parent Common Stock are exercisable and
  "C" is the fully diluted capitalization of the Company immediately prior to
  the Effective Time, expressed as the sum of (A) the number of shares of
  Company Common Stock outstanding, (B) the number of shares of Company
  Common Stock issuable upon conversion of the outstanding shares of Company
  Preferred Stock and (C) the aggregate number of shares of Company Common
  Stock for which outstanding warrants, options or other rights to acquire
  Company Common Stock are exercisable (such fully diluted capitalization
  being referred to herein as the "Company Fully Diluted Capitalization").
 
    (ii) As used herein, the "Valuation Formula Ratio" shall be determined
  according to the following formula:
 
                                 $150,000,000
                                   ---------
                               D =
                                    (E x C)
 
  , where "D" is the Valuation Formula Ratio, expressed to six digits to the
  right of the decimal place, "E" is the average of the closing sale prices
  of Parent Common Stock for the ten trading days ending (and
 
                                      A-2
<PAGE>
 
  including) the trading day two business days prior to the date of the
  Parent Stockholders' Meeting, adjusted to reflect the Reverse Stock Split,
  and "C" is the Company Fully Diluted Capitalization.
 
    (iii) If, between the date of this Agreement and the Effective Time, the
  outstanding shares of Company Capital Stock or Parent Common Stock are
  changed into a different number or class of shares by reason of any stock
  split, stock dividend, reverse stock split, reclassification,
  recapitalization or other similar, then the Exchange Ratio shall be
  appropriately adjusted. The Exchange Ratio already contemplates the Reverse
  Stock Split, and to the extent the Reverse Stock Split is implemented, no
  further adjustments to the Exchange Ratio are required.
 
  (c) If any shares of Company Common Stock outstanding immediately prior to
the Effective Time are unvested or are subject to a repurchase option, risk of
forfeiture or other condition under any applicable restricted stock purchase
agreement or other agreement with the Company or under which the Company has
any rights, then the shares of Parent Common Stock issued in exchange for such
shares of Company Common Stock will also be unvested and subject to the same
repurchase option, risk of forfeiture or other condition, and the certificates
representing such shares of Parent Common Stock may accordingly be marked with
appropriate legends. The Company shall take all action that may be necessary
to ensure that, from and after the Effective Time, Parent is entitled to
exercise any such repurchase option or other right set forth in any such
restricted stock purchase agreement or other agreement.
 
  (d) No fractional shares of Parent Common Stock shall be issued in
connection with the Merger, and no certificates or scrip for any such
fractional shares shall be issued. Any holder of Company Capital Stock who
would otherwise be entitled to receive a fraction of a share of Parent Common
Stock (after aggregating all fractional shares of Parent Common Stock issuable
to such holder) shall, in lieu of such fraction of a share and, upon surrender
of such holder's Company Stock Certificate(s) (as defined in Section 1.6), be
paid in cash the dollar amount (rounded to the nearest whole cent), without
interest, determined by multiplying such fraction by the closing price of a
share of Parent Common Stock as reported by the Nasdaq National Market on the
date the Merger becomes effective.
 
  (e) At the Effective Time, all rights with respect to Company Common Stock
under each Company Option then outstanding under the Company Plans (as defined
in Section 2.3(b)) shall be converted into and become rights with respect to
Parent Common Stock, and Parent shall assume each such Company Option in
accordance with the terms (as in effect as of the date of this Agreement) of
the Company Plan under which it was issued and the stock option agreement by
which it is evidenced. From and after the Effective Time, (i) each Company
Option assumed by Parent may be exercised solely for shares of Parent Common
Stock, (ii) the number of shares of Parent Common Stock subject to each such
Company Option shall be equal to the number of shares of Company Common Stock
subject to such Company Option immediately prior to the Effective Time
multiplied by the Exchange Ratio, rounding down to the nearest whole share
(with cash, less the applicable exercise price, being payable for any fraction
of a share), (iii) the per share exercise price under each such Company Option
shall be adjusted by dividing the per share exercise price under such Company
Option by the Exchange Ratio and rounding up to the nearest hundredth of a
cent and (iv) any restriction on the exercise of any such Company Option shall
continue in full force and effect and the term, exercisability, vesting
schedule and other provisions of such Company Option shall otherwise remain
unchanged; provided, however, that each Company Option assumed by Parent in
accordance with this Section 1.5(e) shall, in accordance with its terms, be
subject to further adjustment as appropriate to reflect any stock split, stock
dividend, reverse stock split, reclassification, recapitalization or other
similar transaction subsequent to the Effective Time. Parent shall file with
the SEC, no later than 30 days after the date on which the Form S-4
Registration Statement becomes effective (and in any event prior to the
Merger), a registration statement on Form S-8 relating to the shares of Parent
Common Stock issuable with respect to the Company Options and the Company
Plans assumed by Parent in accordance with this Section 1.5(e).
 
  (f) At the Effective Time, all rights with respect to Company Warrants then
outstanding shall be converted into and become rights with respect to Parent
Common Stock, and Parent shall assume each such Company
 
                                      A-3
<PAGE>
 
Warrant in accordance with the terms (as in effect as of the date of this
Agreement) of the Warrant by which it is evidenced. From and after the
Effective Time, (i) each Company Warrant assumed by Parent may be exercised
solely for shares of Parent Common Stock, (ii) the number of shares of Parent
Common Stock subject to each such Company Warrant shall be equal to the number
of shares of Company Common Stock subject to such Company Warrant immediately
prior to the Effective Time multiplied by the Exchange Ratio, rounding down to
the nearest whole share (with cash, less the applicable exercise price, being
payable for any fraction of a share), and (iii) the per share exercise price
under each such Company Warrant shall be adjusted by dividing the per share
exercise price under such Company Warrant by the Exchange Ratio and rounding
up to the nearest hundredth of a cent; provided, however, that each Company
Warrant assumed by Parent in accordance with this Section 1.5(f) shall, in
accordance with its terms, be subject to further adjustment as appropriate to
reflect any stock split, stock dividend, reverse stock split,
reclassification, recapitalization or other similar transaction subsequent to
the Effective Time.
 
  1.6 CLOSING OF THE COMPANY'S TRANSFER BOOKS. At The Effective Time: (a) All
Shares Of Company Capital Outstanding Immediately Prior To The Effective Time
Shall Automatically Be Canceled And Retired And Shall Cease To Exist, And All
Holders Of Certificates Representing Shares Of Company Capital Stock That Were
Outstanding Immediately Prior To The Effective Time Shall Cease To Have Any
Rights As Stockholders Of The Company; And (b) The Stock Transfer Books Of The
Company Shall Be Closed With Respect To All Shares Of Company Capital Stock
Outstanding Immediately Prior To The Effective Time. No Further Transfer Of
Any Such Shares Of Company Capital Stock Shall Be Made On Such Stock Transfer
Books After The Effective Time. If, After The Effective Time, A Valid
Certificate Previously Representing Any Shares Of Company Capital Stock (a
"company Stock Certificate") Is Presented To The Exchange Agent (as Defined In
Section 1.7) Or To The Surviving Corporation Or Parent, Such Company Stock
Certificate Shall Be Canceled And Shall Be Exchanged As Provided In Section
1.7.
 
  1.7 EXCHANGE OF CERTIFICATES.
 
  (a) On or prior to the Closing Date, ChaseMellon Shareholder Services, LLC
shall act as exchange agent in the Merger (the "Exchange Agent"). Promptly
after the Effective Time, Parent shall deposit with the Exchange Agent (i)
blank certificates representing the shares of Parent Common Stock issuable
pursuant to this Section 1 and (ii) cash sufficient to make payments in lieu
of fractional shares in accordance with Section 1.5(d). The shares of Parent
Common Stock and cash amounts so deposited with the Exchange Agent, together
with any dividends or distributions received by the Exchange Agent with
respect to such shares, are referred to collectively as the "Exchange Fund."
 
  (b) As soon as reasonably practicable after the Effective Time, the Exchange
Agent will mail to the holders of Company Stock Certificates (i) a letter of
transmittal in customary form and containing such provisions as Parent may
reasonably specify (including a provision confirming that delivery of Company
Stock Certificates shall be effected, and risk of loss and title to Company
Stock Certificates shall pass, only upon delivery of such Company Stock
Certificates to the Exchange Agent) and (ii) instructions for use in effecting
the surrender of Company Stock Certificates in exchange for certificates
representing Parent Common Stock. Upon surrender of a Company Stock
Certificate to the Exchange Agent for exchange, together with a duly executed
letter of transmittal and such other documents as may be reasonably required
by the Exchange Agent or Parent, (1) the holder of such Company Stock
Certificate shall be entitled to receive in exchange therefor a certificate
representing the number of whole shares of Parent Common Stock that such
holder has the right to receive pursuant to the provisions of Section 1.5 (and
cash in lieu of any fractional share of Parent Common Stock in accordance with
Section 1.5(d)), and (2) the Company Stock Certificate so surrendered shall be
canceled. Until surrendered as contemplated by this Section 1.7, each Company
Stock Certificate shall be deemed, from and after the Effective Time, to
represent only the right to receive shares of Parent Common Stock (and cash in
lieu of any fractional share of Parent Common Stock) as contemplated by this
Section 1. If any Company Stock Certificate shall have been lost, stolen or
destroyed, Parent may, in its discretion and as a condition precedent to the
issuance of any certificate representing Parent Common Stock, require the
owner of such lost, stolen or destroyed Company Stock Certificate to provide
an appropriate affidavit (but in no event a surety bond) as
 
                                      A-4
<PAGE>
 
indemnity against any claim that may be made against the Exchange Agent,
Parent or the Surviving Corporation with respect to such Company Stock
Certificate.
 
  (c) No dividends or other distributions declared or made with respect to
Parent Common Stock with a record date after the Effective Time shall be paid
to the holder of any unsurrendered Company Stock Certificate with respect to
the shares of Parent Common Stock represented thereby until such holder
surrenders such Company Stock Certificate in accordance with this Section 1.7
(at which time such holder shall be entitled, subject to the effect of
applicable escheat or similar laws, to receive all such dividends and
distributions, without interest).
 
  (d) Any portion of the Exchange Fund that remains undistributed to holders
of Company Stock Certificates as of the date 180 days after the date on which
the Merger becomes effective shall be delivered to Parent upon demand, and any
holders of Company Stock Certificates who have not theretofore surrendered
their Company Stock Certificates in accordance with this Section 1.7 shall
thereafter look only to Parent for satisfaction of their claims for Parent
Common Stock, cash in lieu of fractional shares of Parent Common Stock and any
dividends or distributions with respect to Parent Common Stock.
 
  (e) Each of the Exchange Agent, Parent and the Surviving Corporation shall
be entitled to deduct and withhold from any consideration payable or otherwise
deliverable pursuant to this Agreement to any holder or former holder of
Company Capital Stock such amounts as may be required to be deducted or
withheld therefrom under the Code or any provision of state, local or foreign
tax law or under any other applicable Legal Requirement. To the extent such
amounts are so deducted or withheld, such amounts shall be treated for all
purposes under this Agreement as having been paid to the Person to whom such
amounts would otherwise have been paid.
 
  (f) Neither Parent nor the Surviving Corporation shall be liable to any
holder or former holder of Company Capital Stock or to any other Person with
respect to any shares of Parent Common Stock (or dividends or distributions
with respect thereto), or for any cash amounts, delivered to any public
official pursuant to any applicable abandoned property law, escheat law or
similar Legal Requirement.

accurate list of all real property, leaseholds, or other interests in real
property owned by Parent (all such property owned by Parent being referred to

by Parent being referred to herein as the "Parent Leased Real Property").
Parent holds the leasehold interests of the Parent Leased Real Property under
the real property leases described in Part 3.6 of the Parent Disclosure
Schedule.
 
  (b) Parent owns, and has good, valid and marketable title to, all assets
purported to be owned by it, including: (i) all assets reflected on the Parent
Audited Balance Sheet; (ii) all other assets reflected in the books and

identified on Part 3.6 of the Parent Disclosure Schedule. All of said assets
are owned by Parent free and clear of any Encumbrances, except for (1) any
lien for current taxes not yet due and payable, (2) minor liens that have
arisen in the ordinary course of business and that do not (in any case or in
the aggregate) materially detract from the value of the assets subject thereto
or materially impair the operations of Parent and (3) liens described in Part
3.6 of the Parent Disclosure Schedule. All buildings, plants, and structures
owned or leased by Parent lie wholly within the boundaries of the real
property owned or leased by Parent and do not encroach upon the property of,
or otherwise conflict with the property rights of, any other Person.
 
  3.7 RECEIVABLES; INVENTORY.

Balance Sheet, consists of a quality and quantity usable and salable in the

consultants and independent contractors to Parent who are or were involved in,
or who have contributed to, the creation or development of any material Parent
Proprietary Asset have executed and delivered to Parent an agreement
(containing no exceptions to or exclusions from the scope of its coverage)
that is substantially identical to the form of Consultant Confidential
Information and Invention Assignment Agreement previously delivered by Parent
to the Company. No current or former employee, officer, director, stockholder,
consultant or independent contractor has any right, claim or interest in or
with respect to any Parent Proprietary Asset. Parent has not disclosed or
delivered to any Person, or permitted the disclosure or delivery to any escrow
agent or other Person, of the source code, or any portion or aspect of the
source code, or any proprietary information or algorithm contained in any
source code, of any Parent Proprietary Asset.
 
  (c) To the best knowledge of Parent: (i) all patents, trademarks, service
marks and copyrights held by Parent are valid, enforceable and subsisting;

Person) infringes, misappropriates or conflicts with any Proprietary Asset
owned or used by any other Person; (iii) none of the products that are or have
been designed, created, developed, assembled, manufactured or sold by Parent

unauthorized use of, and Parent has not received any notice or other
communication (in writing or otherwise) of any actual, alleged, possible or
potential infringement, misappropriation or unlawful or unauthorized use of,
any Proprietary Asset owned or used by any other Person; (iv) no other Person
is infringing, misappropriating or making any unlawful or unauthorized use of,
and no Proprietary Asset owned or used by any other Person infringes or

to exploit fully any material Parent Proprietary Assets or to transact
business in any market or geographical area or with any Person.

recent determination letter received from the Internal Revenue Service with
respect to such Parent Plan (if such Parent Plan is intended to be qualified
under Section 401(a) of the Code).
 
  (e) Parent is not and has never been required to be treated as a single
employer with any ERISA Affiliate. Parent has never been a member of an
"affiliated service group" within the meaning of Section 414(m) of the Code
with any other Person within the United States. Neither Parent nor any ERISA
Affiliate has ever made a complete or partial withdrawal from a multiemployer
plan, as such term is defined in Section 3(37) of ERISA, that is maintained
within the United States, resulting in "withdrawal liability," as such term is
defined in Section 4201 of ERISA (without regard to subsequent reduction or
waiver of such liability under either Section 4207 or 4208 of ERISA).
 
  (f) Neither Parent nor any ERISA Affiliate has any plan or commitment to
create any additional Parent Welfare Plans or Parent Pension Plans, or to
modify or change any existing Parent Welfare Plan or Parent Pension Plan
(other than to comply with applicable law) in a manner that would affect any
employee of Parent or any ERISA Affiliate.
 
  (g) Except as set forth in Part 3.16(k) of the Parent Disclosure Schedule,
no Parent Plan provides death, medical or health benefits (whether or not
insured) with respect to any current or former employee of Parent or any ERISA
Affiliate after any such employee's termination of service (other than benefit
coverage mandated by applicable law, including coverage provided pursuant to
COBRA).
 
  (h) With respect to any Parent Plan constituting a group health plan within
the meaning of Section 4980B(g)(2) of the Code or Section 607(1) of ERISA, the
provisions of COBRA have been complied with in all material respects.
 
  (i) Each of the Parent Plans has been operated and administered in all
material respects in accordance with applicable Legal Requirements, including
but not limited to ERISA and the Code.
 
                                     A-27
<PAGE>
 
  (j) Each of the Parent Plans intended to be qualified under Section 401(a)
of the Code has received a favorable determination as to its qualification
from the Internal Revenue Service, and nothing has occurred that would
adversely affect such qualification.
 
  (k) Except as set forth in Part 3.16(k) of the Parent Disclosure Schedule,
neither the execution, delivery or performance of this Agreement, nor the
consummation of the Merger or any of the other transactions contemplated by
this Agreement, will result in any payment (including any bonus, golden
parachute or severance payment) to any current or former employee or director
of Parent (whether or not under any Parent Plan), or materially increase the
benefits payable under any Parent Plan, or result in any acceleration of the
time of payment or vesting of any such benefits.
 
  (l) Part 3.16(l) of the Parent Disclosure Schedule contains a list of all
salaried employees of Parent located in the United States or any ERISA
Affiliate as of the date of this Agreement whose salaries are in excess of
$150,000 per year, and correctly reflects, in all material respects, their
salaries, any other compensation payable to them (including compensation
payable pursuant to bonus, deferred compensation or commission arrangements),
their dates of employment and their positions. Neither Parent nor any ERISA
Affiliate is a party to any collective bargaining agreement or other Contract
with a labor union involving any of its employees located in the United
States. There has not been, is not now pending, and no Person has threatened
to commence any slowdown, work stoppage, labor or dispute or union organizing
activity or any similar activity or dispute in the United States affecting
Parent or any ERISA Affiliates or their employees. All of the employees of
Parent and any ERISA Affiliates are "at will" employees.
 
  (m) Part 3.16(m) of the Parent Disclosure Schedule identifies each employee
of Parent or any ERISA Affiliate who is not fully available to perform work
because of disability or other leave and sets forth the basis of such leave
and the anticipated date of return to full service.
 
  (n) Parent and each ERISA Affiliate are in compliance in all material
respects with all applicable Legal Requirements and Contracts relating to
employment, employment practices, wages, bonuses and terms and conditions of
employment, including employee compensation matters.
 
  (o) Parent has good labor relations, and Parent has no knowledge of any
facts indicating that (i) the consummation of the Merger or any of the other
transactions contemplated by this Agreement will have a material adverse
effect on the labor relations of Parent, or that (ii) any of the key employees
of Parent intends to terminate his or her employment with Parent.
 
  3.17 ENVIRONMENTAL MATTERS.
 
  (a) Except as set forth in Part 3.17(a) of the Parent Disclosure Schedule,
Parent is, and at all times has been, in compliance in all material respects
with all applicable Environmental Laws, which compliance includes (i) the
possession by Parent of all permits and other Governmental Authorizations
required under applicable Environmental Laws, and (ii) compliance with the
terms and conditions thereof (and the violation of which would have a Material
Adverse Effect).
 
  (b) Except as set forth in Part 3.17(b) of the Parent Disclosure Schedule,
Parent has not received any notice or other communication (in writing or
otherwise), whether from a Governmental Body, citizens group, employee or
otherwise, that alleges that Parent is not in compliance with any
Environmental Law or is or may be required to undertake or bear any
Environmental Liabilities. To the best knowledge of Parent, there are no
circumstances that may prevent or interfere with the compliance by Parent with
any Environmental Law or that may require Parent to undertake or bear any
Environmental Liabilities in the future (other than routine Environmental
Liabilities incurred in the ordinary course of business consistent with past
practices) with respect to any Parent Property, any other property or
otherwise. To the best knowledge of Parent, no current or prior owner of any
Parent Property has received any notice or other communication (in writing or
otherwise), whether from a Government Body, citizens group, employee or
otherwise, that alleges that such current or prior owner or Parent
 
                                     A-28
<PAGE>
 
has not been or is not in compliance with any Environmental Law or is or may
be required to undertake or bear any Environmental Liabilities.
 
  (c) (i) To the best knowledge of Parent all Parent Property and all surface
water, groundwater and soil associated with such Parent Property and (ii) to
the knowledge of Parent without independent investigation, all Property to
which Parent has sent any Material of Environmental Concern are free of any
material environmental contamination by any Material of Environmental Concern
in any concentration that may require any costs of investigation, response,
removal or remedial action.
 
  (d) Parent has delivered to the Company true and complete copies and results
of any reports, studies, analyses, tests, or monitoring possessed or initiated
by Parent pertaining to Materials of Environmental Concern in, on, or under
any Parent Property, or concerning compliance by Parent, or any other Person
for whose conduct it is or may be held responsible, with Environmental Laws.
 
  (e) For purposes of this Section 3.17, "Parent Property" shall include any
property, parcel or facility now or heretofore owned, leased, used or
controlled by Parent or geologically or hydrologically adjoining any such
property, parcel or facility.
 
  3.18 INSURANCE. Parent has delivered to the Company a copy of each material
insurance policy and each material self insurance program relating to the
business, assets or operations of Parent in the United States. Each such
insurance policy is in full force and effect. Since December 31, 1994, Parent
has not received any notice or other communication regarding any actual or
possible (a) cancellation or invalidation of any insurance policy, (b) refusal
of any coverage or rejection of any material claim under any insurance policy,
or (c) material adjustment in the amount of the premiums payable with respect
to any insurance policy. Except as set forth in Part 3.18 of the Parent
Disclosure Schedule, there is no pending claim (including any workers'
compensation claim) under or based upon any insurance policy applicable to the
business, assets or operations of Parent.
 
  3.19 TRANSACTIONS WITH AFFILIATES. Except as set forth in the Parent SEC
Reports, since the date of Parent's last proxy statement filed with the SEC,
no event has occurred that would be required to be reported by Parent pursuant
to Item 404 of Regulation S-K promulgated by the SEC. Part 3.19 of the Parent
Disclosure Schedule identifies each person who is an "affiliate" (as that term
is used in Rule 145 under the Securities Act) of Parent as of the date of this
Agreement.
 
  3.20 LEGAL PROCEEDINGS; ORDERS.
 
  (a) Except as set forth in Part 3.20 of the Parent Disclosure Schedule,
there is no pending Legal Proceeding, and (to the best knowledge of Parent) no
Person has threatened to commence any Legal Proceeding: (i) that involves
Parent or any of the assets owned or used by Parent; or (ii) that challenges,
or that may have the effect of preventing, delaying, making illegal or
otherwise interfering with, the Merger or any of the other transactions
contemplated by this Agreement. To the best knowledge of Parent, no event has
occurred, and no claim, dispute or other condition or circumstance exists,
that will, or that could reasonably be expected to, give rise to or serve as a
basis for the commencement of any such Legal Proceeding.
 
  (b) There is no material order, writ, injunction, judgment or decree to
which Parent, or any of the assets owned or used by Parent, is subject. To the
best knowledge of Parent, no officer or key employee of Parent is subject to
any order, writ, injunction, judgment or decree that prohibits such officer or
other employee from engaging in or continuing any conduct, activity or
practice relating to the business of Parent.
 
  3.21 AUTHORITY; BINDING NATURE OF AGREEMENT. Parent and Merger Sub have the
absolute and unrestricted right, power and authority to enter into and to
perform their obligations under this Agreement. The Board of Directors of
Parent (at a meeting duly called and held) has (a) unanimously determined that
the Merger is advisable and fair and in the best interests of the Company and
its stockholders, (b) unanimously authorized and approved the execution,
delivery and performance of this Agreement by Parent and has unanimously

authorized Parent Common Stock, and (c) unanimously recommended the adoption
of this Agreement by the holders of Parent Common Stock and directed that this
Agreement be submitted for consideration by Parent's stockholders at the

enforceable against them in accordance with its terms, subject to (i) laws of
general application relating to bankruptcy, insolvency and the relief of
debtors, and (ii) rules of law governing specific performance, injunctive
relief and other equitable remedies.
 
  3.22 SECTION 203 OF THE DGCL NOT APPLICABLE. As of the date hereof and at

shall have violated any of the restrictions set forth in this Section 5.3(a),
(2) the Board of Directors of Parent concludes in good faith, based upon the
advice of its outside legal counsel, that failure to do so would create a
substantial risk of liability for breach of its fiduciary obligations to

nonpublic information to, or entering into discussions with, such Person,
Parent gives the Company written notice of the identity of such Person and of
Parent's intention to furnish nonpublic information to, or enter into
discussions with, such Person, and Parent receives from such Person an

Person by or on behalf of Parent, and (4) prior to furnishing any such

(the "Reverse Stock Split Ratio"), such that, in one or more steps, each one
hundred fifty (150) outstanding shares of Parent Common Stock shall be

Stockholders' Meeting, contain any untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary in order
to make the statements therein, in the light of the circumstances under which
they are made, not misleading. The Joint Proxy Statement/Prospectus will

  6.5 INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
  (a) From and after the Effective Time, Parent will cause the Surviving
Corporation to fulfill and honor in all respects the obligations of the
Company pursuant to (i) each indemnification agreement currently in effect
between Parent and each person who is or was a director or officer of Parent
at or prior to the Effective Time and (ii) any indemnification provision under
the Company's Certificate of Incorporation or By-Laws and any indemnification
provision under Parent's Certificate of Incorporation or By-Laws, all as is in
effect on the date hereof (the persons to be indemnified pursuant to the
agreements or provisions referred to in this Section 6.5(a) shall be referred
to as, collectively, the "Indemnified Parties"). The Certificate of
Incorporation and By-Laws of the Surviving Corporation shall contain the
provisions with respect to indemnification and exculpation from liability set
forth in the Company's Certificate of Incorporation and By-Laws on the date of
this Agreement, which provisions shall not be amended, repealed or otherwise
modified for a period of six years after the Effective Time in any manner that
would adversely affect the rights thereunder of any Indemnified Party.
 
  (b) Without limiting the provisions of Section 6.5(a), during the period
ending six years after the Effective Time, Parent will indemnify and hold
harmless each Indemnified Party against and from any costs or expenses
(including reasonable attorneys' fees), judgments, fines, losses, claims,
damages, liabilities and amounts paid in settlement in connection with any
claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, to the extent such claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, to the extent such claim, action, suit, proceeding or
investigation arises out of or pertains to (1) any action or omission or
alleged action or omission in his or her capacity as a director or officer of
the Company, Parent or any of their subsidiaries (regardless of whether such
action or omission, or alleged action or omission, occurred prior to, on or
after the Closing Date) or (2) any of the transactions contemplated by this
Agreement, in each case to the full extent a corporation is permitted under
the DGCL to indemnify its own directors and officers, as the case may be;
provided, however, that if, at any time prior to the sixth anniversary of the
Effective Time, any Indemnified Party delivers to Parent a written notice
asserting a claim for indemnification under this Section 6.5(b), then the
claim asserted in such notice shall survive the sixth anniversary of the
Effective Time until such time as such claim is fully and finally resolved. In
the event of any such claim, action, suit, proceeding or investigation, (i)
Parent will have the right to control the defense thereof after the Effective
Time (it being understood that, by electing to control the defense thereof,
Parent will be deemed to have waived any right to object to the indemnified
Parties' entitlements to indemnification hereunder with respect thereto), (ii)
any counsel retained by the Indemnified Parties with respect to the defense
thereof for any period after the Effective Time must be reasonably
satisfactory to Parent, and (iii) after the Effective Time, Parent will pay
the reasonable fees and expenses of such counsel, promptly after statements
therefor are received (provided that in the event that any Indemnified Party
is not entitled to indemnification hereunder, any amounts advanced on his or
her behalf shall be remitted to the Surviving Corporation); provided, however,
that neither Parent nor the Surviving Corporation nor any Indemnified Party,
will be liable for any settlement effected without its express written
consent. The Indemnified Parties as a group may retain only one law firm (in
addition to local counsel) to represent them with respect to any single action
unless counsel for any Indemnified Party determines in good faith that, under
applicable standards of professional conduct, a conflict exists or is
reasonably likely to arise on any material issue between the positions of any
two or more Indemnified Parties. Notwithstanding anything to the contrary
contained in this Section 6.5(b) or elsewhere in this Agreement, Parent agrees
that it will not settle or compromise or consent to the entry of any judgment
or otherwise seek termination with respect to any claim, action, suit,
proceeding or investigation for which indemnification may be sought under this
Agreement unless such settlement, compromise, consent or termination includes
an unconditional release of all Indemnified Parties from all liability arising
out of such claim, action, suit, proceeding or investigation. Without limiting
the foregoing, in any case in which approval of or a determination by the
Surviving Corporation is required to effectuate any indemnification, the
Indemnified Parties will conclusively be deemed to have met the applicable
standards for indemnification with respect to any actions or omissions of such
Indemnified Parties as an officer or director of the Company or Parent on or
prior to the Effective Time relating to any of the transactions contemplated
by this Agreement.
 
                                     A-39
<PAGE>
 
  (c) Parent and the Surviving Corporation jointly and severally agree to pay
all expenses, including attorneys' fees, that may be incurred by the
Indemnified Parties in enforcing the indemnity and other obligations provided
for in this Section 6.5.
 
  (d) Parent shall maintain in effect for a period of three years after the
Effective Time the policy of officers' and directors' liability insurance
maintained by Parent on the date of this Agreement, with coverage in amount
and scope at least as favorable as the Parent's existing directors' and
officers' liability insurance coverage, provided that such policy shall not be
required to be maintained if equivalent coverage is provided to such Persons
under another policy of officers' and directors' liability insurance; and
provided further that in no event shall Parent be required to expend in any
one year an amount in excess of 150% of the annual premium currently paid by
Parent for such insurance; and provided further, that if the annual premiums
of such insurance coverage exceed such amount, Parent shall be obligated to
obtain a policy with the greatest coverage available for a cost not exceeding
such amount.
 
  (e) This Section 6.5 shall survive the consummation of the Merger and the
Effective Time, is intended to benefit and may be enforced by the Company,
Parent, the Surviving Corporation and the Indemnified Parties, and shall be
binding on all successors and assigns of Parent and the Surviving Corporation.
 
  6.6 ADDITIONAL AGREEMENTS.

reasonable efforts to take, or cause to be taken, all actions necessary to

Section 6.6(b), each party to this Agreement (i) shall make all filings (if

Agreement, (ii) shall use all reasonable efforts to obtain each Consent (if
any) required to be obtained (pursuant to any applicable Legal Requirement or
Contract, or otherwise) by such party in connection with the Merger or any of
the other transactions contemplated by this Agreement, and (iii) shall use all
reasonable efforts to lift any restraint, injunction or other legal bar to the
Merger. Each party shall promptly deliver to the other party a copy of each
such filing made, each such notice given and each such Consent obtained by
such party during the Pre-Closing Period.
 
  (b) Notwithstanding anything to the contrary contained in this Agreement,
neither Parent nor the Company shall have any obligation under this Agreement

to license or otherwise make available to any Person any technology, software
or other Proprietary Asset; (iv) to hold separate any assets or operations
(either before or after the Closing Date); or (v) to make any commitment (to
any Governmental Body or otherwise) regarding its future operations.
 
  6.7 DISCLOSURE. Parent and the Company shall consult with each other before
issuing any press release or otherwise making any public statement with
respect to the Merger or any of the other transactions contemplated by this
Agreement. Without limiting the generality of the foregoing, neither party
shall, nor shall permit any of its Representatives to, make any disclosure
regarding the Merger or any of the other transactions contemplated by this
Agreement unless (a) the other party shall have approved such disclosure or
(b) the party making such disclosure shall have been advised in writing by its
outside legal counsel that such disclosure is required by applicable law.
 
  6.8 AFFILIATE AGREEMENTS. The Company shall use all reasonable efforts to
cause each Person identified in Part 2.19 of the Acquired Corporation
Disclosure Schedule and each other Person who is or becomes an "affiliate" (as

execute and deliver to Parent, prior to the date of the mailing of the Joint
Proxy Statement/Prospectus to the Company's stockholders, an Affiliate
Agreement in the form of Exhibit D.

resignation of each officer and director of Parent, other than the resignation

entered into by an employee of Parent, and which is delivered by such employee
at the request of the Company, shall be considered for all purposes a

  6.12 REGISTRATION RIGHTS AGREEMENT. Parent shall execute and enter into a
Registration and Stockholder Rights Agreement, in the form of Exhibit G, with

  1.2 DEMAND REGISTRATION
 
  (a) If at any time after the date hereof, the Company shall receive a
written request from the Stockholder that the Company file a registration
statement under the Act covering the registration of at least twenty five
percent (25%) of the Registrable Securities then outstanding (or a lesser
percent if the anticipated aggregate offering price, net of underwriting
discounts and commissions, would exceed $5,000,000), then the Company shall:
 
    (i) effect as soon as practicable, and in any event within 90 days after
  receipt of such request, the registration under the Act of all Registrable
  Securities which the Stockholder request to be registered.

<PAGE>
 
  (b) If the Stockholder intends to distribute the Registrable Securities
covered by its request by means of an underwriting, it shall so advise the
Company as a part of its request made pursuant to subsection 1.2(a). The
underwriter or underwriters will be selected by the Stockholder and shall be
reasonably acceptable to the Company. The Stockholder (together with the
Company as provided in subsection 1.4(e)) shall enter into an underwriting

  (c) The Company shall not be obligated to effect, or to take any action to
effect, any registration pursuant to this Section 1.2:
 
    (i) if more than one registration has been effected pursuant to this
  Section 1.2 in any preceding twelve (12) month period and such registration

  have been declared or ordered effective overall;
 
    (ii) During the period starting with the date thirty (30) days prior to

  by the Chairman of the Board stating that in the good faith judgment of the

securities under the Act in connection with the public offering of such
securities solely for cash (other than a registration relating solely to the
sale of securities to participants in a Company employee benefit plan, a
registration on any form which does not include substantially the same
information as would be required to be included in a registration statement
covering the sale of the Registrable Securities or a registration in which the
only Common Stock being registered is Common Stock issuable upon conversion of
debt securities which are also being registered), the Company shall, at such
time, promptly give the Stockholder written notice of such registration. Upon
the written request of the Stockholder given within twenty (20) days after
mailing of such notice by the Company in accordance with Section 3.5, the
Company shall, subject to the provisions of Section 1.7, cause to be
registered under the Act all of the Registrable Securities that the
Stockholder has requested to be registered.

securities in such registration. The Registration Expenses of such withdrawn
registration shall be borne by the Company in accordance with Section 1.6
hereof.
 
  1.4 OBLIGATIONS OF THE COMPANY. Whenever required under this Section 1 to
effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:
 
    (a) Prepare and file with the SEC a registration statement with respect
  to such Registrable Securities and use its reasonable best efforts to cause
  such registration statement to become effective, and, upon the request of
  the Stockholder, keep such registration statement effective for a period of
  up to one hundred twenty (120) days or until the distribution contemplated
  in the Registration Statement has been completed;
 
                                     A-55

  provided, however, that such 120-day period shall be extended for a period
  of time equal to the period the Stockholder refrains from selling any
  securities included in such registration at the request of an underwriter
  of Common Stock (or other securities) of the Company.
 
    (b) Prepare and file with the SEC such amendments and supplements to such
  registration statement and the prospectus used in connection with such
  registration statement as may be necessary to comply with the provisions of
  the Act with respect to the disposition of all securities covered by such
  registration statement; provided that, except as to a registration
  statement and prospectus pursuant to Section 1.3 hereof, the Company shall
  not file any amendment or supplement to such registration statement or
  prospectus to which the Stockholder shall have reasonably objected on the
  grounds that such amendment or supplement does not comply in all material
  respects with the requirements of the Act, having been furnished with a
  copy thereof at the earliest practicable date.
 
    (c) Furnish to the Stockholder such numbers of copies of a prospectus,
  including a preliminary prospectus, in conformity with the requirements of
  the Act, and such other documents as the Stockholder may reasonably request
  in order to facilitate the disposition of Registrable Securities owned by
  the Stockholder.
 
    (d) Use its reasonable best efforts to register and qualify the
  securities covered by such registration statement under such other
  securities or Blue Sky laws of such jurisdictions as shall be reasonably
  requested by the Stockholder; provided that the Company shall not be
  required in connection therewith or as a condition thereto to qualify to do
  business or to file a general Consent to service of process in any such
  states or jurisdictions, unless the Company is already subject to service
  in such jurisdiction and except as may be required by the Act.
 
    (e) In the event of any underwritten public offering, enter into and
  perform its obligations under an underwriting agreement, in usual and
  customary form, with the managing underwriter of such offering. The
  Stockholder participating in such underwriting shall also enter into and
  perform its obligations under such an agreement.
 
    (f) Notify the Stockholder at any time when a prospectus relating to the
  registration of Registrable Securities is required to be delivered under
  the Act of the happening of any event as a result of which the prospectus
  included in such registration statement, as then in effect, includes an
  untrue statement of a material fact or omits to state a material fact
  required to be stated therein or necessary to make the statements therein
  not misleading in the light of the circumstances then existing.
 
    (g) Cause all such Registrable Securities registered pursuant hereunder
  to be listed on each securities exchange on which similar securities issued
  by the Company are then listed.
 
    (h) Provide a transfer agent and registrar for all Registrable Securities
  registered pursuant hereunder and a CUSIP number for all such Registrable
  securities, in each case not later than the effective date of such
  registration.
 
    (i) Use its reasonable best efforts to furnish, at the request of the
  Stockholder, on the date that such Registrable Securities are delivered to
  the underwriters for sale in connection with a registration pursuant to
  this Section 1, if such securities are being sold through underwriters, or,
  if such securities are not being sold through underwriters, on the date
  that the registration statement with respect to such securities becomes
  effective, (i) an opinion, dated such date, of the counsel representing the
  Company for the purposes of such registration, in form and substance as is
  customarily given to underwriters in an underwritten public offering,
  addressed to the underwriters, if any, and to the Stockholder and (ii) a
  letter dated such date, from the independent certified public accountants
  of the Company, in form and substance as is customarily given by
  independent certified public accountants to underwriters in an underwritten
  public offering, addressed to the underwriters, if any, and, if permitted
  by applicable accounting standards, to the Stockholder (or if delivery of
  such letter is not permitted by applicable accounting standards, deliver to
  the Stockholder a copy of such letter addressed to the underwriters, if
  any).
 
  1.5 EXPENSES OF DEMAND REGISTRATION AND S-3 REGISTRATION. All expenses,
other than underwriting discounts and commissions, incurred in connection with
the first registration pursuant to this Agreement (other
 
                                     A-56
<PAGE>
 
than pursuant to Section 1.3) and related filings or qualifications, including

printers' and accounting fees, and the reasonable fees and disbursements of
counsel for the Company (collectively, the "Registration Expenses") shall be
borne as follows: (i) the Company shall pay the lesser of (A) fifty percent
(50%) of the Registration Expenses or (B) $100,000, and (ii) the Stockholder
shall pay the remaining Registration Expenses. The Stockholder shall pay (i)
one hundred percent (100%) of all Registration Expenses incurred following the

expenses incurred in connection with any registration, filing or qualification
of Registrable Securities with respect to the registrations pursuant to
Section 1.3 for the Stockholder (which right may be assigned as provided in

qualification fees, printers and accounting fees relating or apportionable
thereto but excluding underwriting discounts and commissions relating to
Registrable Securities. The fees and disbursements of any counsel retained by
the Stockholder in connection with any such registrations shall be paid by the
Stockholder.
 
  1.7 UNDERWRITING REQUIREMENTS. In connection with any offering involving an
underwriting of shares of the Company's capital stock, the Company shall not
be required under Section 1.3 to include any of the Stockholder's securities
in such underwriting unless the Stockholder accepts the terms of the
underwriting as agreed upon between the Company and the underwriters selected
by it (or by other persons entitled to select the underwriters), and then only
in such quantity as the underwriters determine in their sole discretion will
not, jeopardize the success of the offering by the Company. If the total
amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters determine in their sole
discretion is compatible with the success of the offering, then the Company
shall be required to include in the offering only that number of such
securities, including Registrable Securities, which the underwriters determine
in their sole discretion will not jeopardize the success of the offering (the
securities so included to be apportioned pro rata among the selling
stockholders according to the total amount of securities entitled to be
included therein owned by each selling stockholder or in such other
proportions as shall mutually be agreed to by such selling stockholders) but,
except with respect to any one offering pursuant to Section 1.3 following the
first such offering pursuant to Section 1.3 to occur after the closing date of
the Merger, in no event shall the amount of securities of the Stockholder
included in the offering be reduced below twenty five percent (25%) of the
total amount of securities included in such offering. For purposes of the
preceding parenthetical concerning apportionment, for any selling stockholder
which is a Stockholder of Registrable Securities and which is a partnership or
corporation, the partners, retired partners and stockholders of such
Stockholder, or the estates and family members of any such partners and
retired partners and any trusts for the benefit of any of the foregoing
persons shall be deemed to be a single "selling stockholder", and any pro-rata
reduction with respect to such "selling stockholder" shall be based upon the
aggregate amount of shares carrying registration rights owned by all entities
and individuals included in such "selling stockholder", as defined in this
sentence.
 
  1.8 INDEMNIFICATION. In the event any Registrable Securities are included in
a registration statement under this Section 1:
 
    (a) To the extent permitted by law, the Company will indemnify and hold
  harmless the Stockholder, any underwriter (as defined in the Act) for the
  Stockholder and each person, if any, who controls the Stockholder or
  underwriter within the meaning of the Act or the 1934 Act, against any
  losses, claims, damages, or liabilities (joint or several) to which they
  may become subject under the Act, or the 1934 Act or other federal or state
  law, insofar as such losses, claims, damages, or liabilities (or actions in
  respect thereof) arise out of or are based upon any of the following
  statements, omissions or violations (collectively a "Violation"): (i) any
  untrue statement or alleged untrue statement of a material fact contained
  in such registration statement, including any preliminary prospectus or
  final prospectus contained therein or any amendments or supplements
  thereto, (ii) the omission or alleged omission to state therein a material
  fact

  not misleading, or (iii) any violation or alleged violation by the Company
  of the Act, the 1934 Act, any state securities law or any rule or

  securities law; and the Company will reimburse the Stockholder, underwriter
  or controlling person, as incurred, any legal or other expenses reasonably
  incurred by them in connection with investigating or defending any such
  loss, claim, damage, liability, or action; provided, however, that the
  indemnity agreement contained in this subsection 1.8(a) shall not apply to
  amounts paid in settlement of any such loss, claim, damage, liability, or
  action if such settlement is effected without the consent of the Company
  (which consent shall not be unreasonably withheld), nor shall the Company
  be liable in any such case for any such loss, claim, damage, liability, or
  action to the extent that it arises out of or is based upon a Violation
  which occurs in reliance upon and in conformity with written information
  furnished expressly for use in connection with such registration by such
  Stockholder, underwriter or controlling person.
 
    (b) To the extent permitted by law, each Stockholder will indemnify and
  hold harmless the Company, each of its directors, each of its officers who
  has signed the registration statement, each person, if any, who controls
  the Company within the meaning of the Act, any underwriter, any other
  selling stockholder in such registration statement and any controlling
  person of any such underwriter or other selling stockholder, against any
  losses, claims, damages, or liabilities (joint or several) to which any of
  the foregoing persons may become subject, under the Act, or the 1934 Act or
  other federal or state-law, insofar as such losses, claims, damages, or
  liabilities (or actions in respect thereto) arise out of or are based upon

  such Violation occurs in reliance upon and in conformity with written
  information furnished by such Stockholder expressly for use in connection
  with such registration; and such Stockholder will reimburse, as incurred,
  any legal or other expenses reasonably incurred by any person intended to
  be indemnified pursuant to this subsection 1.8(b), in connection with
  investigating or defending any such loss, claim, damage, liability, or
  action; provided, however, that the indemnity agreement contained in this
  subsection 1.8(b) shall not apply to amounts paid in settlement of any such
  loss, claim, damage, liability or action if such settlement is effected
  without the consent of the Stockholder (which consent shall not be
  unreasonably withheld); provided, that, in no event shall any indemnity
  under this subsection 1.8(b) exceed the gross proceeds from the offering
  received by the Stockholder.
 
    (c) Promptly after receipt by an indemnified party under this Section 1.8
  of notice of the commencement of any action (including any governmental
  action), such indemnified party will, if a claim in respect thereof is to
  be made against any indemnifying party under this Section 1.8, deliver to
  the indemnifying party a written notice of the commencement thereof and the
  indemnifying party shall have the right to participate in, and, to the
  extent the indemnifying party so desires, jointly with any other
  indemnifying party similarly noticed, to assume the defense thereof with
  counsel mutually satisfactory to the parties; provided, however, that an
  indemnified party (together with all other indemnified parties which may be
  represented without conflict by one counsel) shall have the right to retain
  one separate counsel, with the fees and expenses to be paid by the
  indemnifying party, 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 such indemnified party and
  any other party represented by such counsel in such proceeding. The failure
  to deliver written notice to the indemnifying party within a reasonable
  time of the commencement of any such action, if prejudicial to its ability
  to defend such action, shall relieve such indemnifying party of any
  liability to the indemnified party under this Section 1.8, but the omission
  so to deliver written notice to the indemnifying party will not relieve it
  of any liability that it may have to any indemnified party otherwise than
  under this Section 1.8.
 
    (d) If the indemnification provided for in this Section 1.8 is held by a
  court of competent jurisdiction to be unavailable to an indemnified party
  with respect to any loss, liability, claim, damage, or expense referred to
  therein, then the indemnifying party, in lieu of indemnifying such
  indemnified party hereunder, shall, to the extent permitted by law,
  contribute to the amount paid or payable by such indemnified party as a
  result of such loss, liability, claim, damage, or expense in such
  proportion as is appropriate to reflect the relative fault of the
  indemnifying party on the one hand and of the indemnified party on the
  other in
 
                                     A-58
<PAGE>
 
  connection with the Violation(s) that resulted in such loss, liability,
  claim, damage, or expense as well as any other relevant equitable
  considerations. The relative fault of the indemnifying party and of the
  indemnified party shall be determined by reference to, among other things,
  whether the untrue or alleged untrue statement of a material fact or the
  omission to state a material fact relates to information supplied by the
  indemnifying party or by the indemnified party and the parties' relative
  intent, knowledge, access to information, and opportunity to correct or
  prevent such statement or omission.
 
    (e) Notwithstanding the foregoing, to the extent that the provisions on
  indemnification and contribution contained in the underwriting agreement
  entered into in connection with the underwritten public offering are in
  conflict with the foregoing provisions, the provisions in the underwriting
  agreement shall control.
 
    (f) The obligations of the Company and the Stockholder under this Section
  1.8 shall survive the completion of any offering of Registrable Securities
  in a registration statement under this Section 1, and the termination of
  this Agreement.
 
  1.9 REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934. With a view to making
available to the Stockholder the benefits of Rule 145 promulgated under the
Act and any other rule or regulation of the SEC that may at any time permit a
Stockholder to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to:
 
    (a) make and keep public information available, as those terms are
  understood and defined in SEC Rule 144, at all times;
 
    (b) take such action as is necessary to enable the Stockholder to utilize
  Form S-3 for the sale of its Registrable Securities;
 
    (c) file with the SEC in a timely manner all reports and other documents
  required of the Company under the Act and the 1934 Act; and
 
    (d) furnish to the Stockholder, so long as the Stockholder owns any
  Registrable Securities, forthwith upon request (i) a written statement by
  the Company that it has complied with the reporting requirements of SEC
  Rule 144, the Act and the 1934 Act, or that it qualifies as a registrant
  whose securities may be resold pursuant to Form S-3 (at any time when it so
  qualifies), (ii) a copy of the most recent annual or quarterly report of
  the Company and such other reports and documents so filed by the Company,
  and (iii) such other information as may be reasonably requested in availing
  the Stockholder of any rule or regulation of the SEC which permits the
  selling of any such securities without registration or pursuant to such
  form.
 
  1.10 FORM S-3 REGISTRATION. In case the Company shall receive from the
Stockholder a written request that the Company effect a registration on Form
S-3 and any related qualification or compliance with respect to all or a part
of the Registrable Securities owned by the Stockholder, the Company will:
 
    (a) as soon as practicable, effect such registration and all such
  qualifications and compliances as may be so requested and as would permit
  or facilitate the sale and distribution of all or such portion of the
  Stockholder's Registrable Securities as are specified in such request;
  provided, however, that the Company shall not be obligated to effect any
  such registration, qualification or compliance, pursuant to this section
  1.10: (A) if Form S-3 is not available for such offering by the
  Stockholder; (B) if the Stockholder proposes to sell Registrable Securities
  and such other securities (if any) at an aggregate price to the public (net
  of any underwriters' discounts or commissions) of less than $500,000; (C)
  if the Company has, within the twelve (12) month period preceding the date
  of such request, already effected two (2) registrations on Form S-3 for the
  Stockholder pursuant to this Section 1.10 or has already effected four (4)
  registrations under this Agreement for the Stockholder (exclusive of
  registrations pursuant to Section 1.3), (D) if the Company shall furnish to
  the Stockholder a certificate signed by the Chairman of the Board of
  Directors of the Company stating that in the good faith judgment of the
  Board of Directors of the Company, it would be seriously detrimental to the
  Company and its stockholders for such Form S-3 Registration to be effected
  at such time, in which event the Company shall have the right to defer the
  filing of the Form S-3 registration statement for a period of not more than
  ninety (90) days after receipt of the request of the Stockholder under this
  Section 1.10; provided, however, that such right to delay a request,
  whether pursuant to this Section 1.10 or
 
                                     A-59
<PAGE>
 
  Section 1.2, shall be exercised by the Company not more than once in any
  twelve (12) month period, or (D) in any particular jurisdiction in which
  the Company would be required to qualify to do business or to execute a
  general consent to service of process in effecting such registration,
  qualification or compliance.
 
    (b) Subject to the foregoing, (i) the Company shall file a registration
  statement covering the Registrable Securities and other securities so
  requested to be registered as soon as practicable after receipt of the
  request or requests of the Stockholder; and (ii) if requested by the
  Stockholder, in a transaction constituting (1) a private placement under
  Section 3(b) or 4(2) of the Act, or (2) under Rule 144A under the Act, the
  Company shall undertake to register such shares after the conclusion of
  such placement to permit such shares freely to be tradeable by the
  purchasers thereof.
 
    (c) The Company shall use its reasonable best efforts to keep any such
  registration described in Section 1.10(b) above , as the case may be,
  continuously effective for the period beginning on the date on which such
  registration is declared effective and ending on the first to occur of (A)
  one hundred twenty (120) days thereafter and (B) on the first date that all
  such Registrable Securities have been sold. During the period during which
  any such registration is effective, the Company shall supplement or make
  amendments to such registration, if required by the Act or if reasonably
  requested by the Stockholder or an underwriter of Registrable Securities,
  including to reflect any specific plan of distribution or method of sale,
  and shall use its reasonable best efforts to have such supplements and
  amendments declared effective as soon as practicable after filing.
 
    (d) Registrations effected pursuant to this Section 1.10 shall not be
  counted as registrations effected pursuant to Sections 1.2 or 1.3 herein.
 
  1.11 ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the Company to
register Registrable Securities pursuant to this Section 1 may be assigned
(but only with all related obligations) by the Stockholder to one or more
transferees or assignees of such securities who hold, pursuant to such
assignment(s), a number of Registrable Securities constituting in excess of
five percent (5%) of the outstanding shares of the Common Stock of the
Company, provided: (a) the Company is, within ten (10) days after any such
transfer, furnished with written notice of the name and address of such
transferees or assignees and the securities with respect to which such
registration rights are being assigned; (b) such transferees or assignees
agrees in writing to be bound by and subject to the terms and conditions of
this Agreement, including without limitation the provisions of Section 1.13
below; and (c) such assignment shall be effective only if immediately
following such transfer the further disposition of such securities by the
transferees or assignees is restricted under the Act. In the event of any
assignment by the Stockholder pursuant to this Section 1.11, any right of the
Stockholder hereunder may only be exercised by written instrument executed by
the holders of at least thirty percent (30%) of the Registrable Securities
then outstanding (the "Written Instrument") and the Company may rely on the
Written Instrument in effecting such right or rights to register Registrable
Securities pursuant to Section 1. Upon any proper assignment of registration
rights in accordance with this Section 1.11, any reduction (pursuant to
Section 1.7) in the participation among holders of Registrable Securities in
any registration subject to Section 1.7 shall, unless the Stockholder and such
other holders of Registrable Securities notify the Company of their agreement
otherwise, be allocated among such holders pro rata in accordance with their
respective holdings of Registrable Securities.
 
  1.12 LIMITATIONS ON SUBSEQUENT REGISTRATION RIGHTS. From and after the date
of this Agreement, the Company shall not, without the prior written consent of
the Stockholder, enter into any agreement with any stockholder or prospective
stockholder of any securities of the Company which would allow such
stockholder or prospective stockholder (a) to include such securities in any
registration filed under Section 1.2 hereof, unless under the terms of such
agreement, such stockholder or prospective stockholder may include such
securities in any such registration only to the extent that the inclusion of
his securities will not reduce the amount of the Registrable Securities of the
Stockholder which is included or (b) to make a demand registration which could
result in such registration statement being declared effective within one
hundred twenty (120) days of the effective date of any registration effected
pursuant to Section 1.2.
 
  1.13 TERMINATION OF REGISTRATION RIGHTS. The rights to registration set
forth in this Section 1 shall terminate as to any particular Registrable
Securities when (i) such Registrable Securities shall have been
 
                                     A-60
<PAGE>
 
effectively registered under the Act and sold by the Stockholder in accordance
with such registration, (ii) such Registrable Securities shall have been sold
in compliance with Rule 145 promulgated under the Act, or (iii) the date which
is four years after the earliest to occur of, after the Closing date of the
Merger, the date of initial listing of the Common Stock of the Company on (1)
the Nasdaq National Market System, (2) the American Stock Exchange, or (3) the
New York Stock Exchange.
 
  1.14 DELAY OF REGISTRATION; FURNISHING INFORMATION.
 
  (a) It shall be a condition precedent to the obligations of the Company to
take any action pursuant to Section 1.2, 1.3 or 1.10 that the Stockholder
shall furnish to the Company such information regarding itself, the
Registrable Securities held by the Stockholder and the intended method of
disposition of such securities as shall be required to effect the registration
of the Stockholder's Registrable Securities.
 
II. COVENANTS
 
  2.1 BOARD OF DIRECTOR MEETINGS. As long as the Stockholder owns not less
than ten percent (10%) of the total number of outstanding shares of Common
Stock of the Company, (A) the Company shall, to the extent that the
Stockholder does not then have a representative as a member of the Board of
Directors of the Company, invite a representative of the Stockholder to attend
all meetings of its Board of Directors in a nonvoting observer capacity and,
in this respect, shall give such representative copies of all notices,
minutes, consents, and other materials that it provides to its directors at
the same time as provided to its directors; provided, however, that such
representative and the Stockholder shall agree to hold in confidence and trust
and to act in a fiduciary manner for the benefit of the stockholders of the
Company with respect to all information so provided, and (B) upon receipt of
the agenda for a meeting of the Board of Directors of the Company or at any
other time, the Stockholder may submit to the Company for discussion and
consideration at the next subsequent meeting of the Board of Directors such
matters as the Stockholder in its sole discretion shall determine.
Notwithstanding the foregoing, the Company may exclude the Stockholder or its
representatives from any deliberation of the Board of Directors if the
Chairman of the Board of Directors delivers, prior to the date of such
deliberation, a letter to the Stockholder stating that legal counsel to the
Company has advised the Board of Directors that such exclusion is necessary to
preserve attorney client privilege.
 
  2.2 INSPECTION AND COOPERATION. As long as the Stockholder owns not less
than ten percent (10%) of the total number of outstanding shares of Common
Stock of the Company, the Company shall permit the Stockholder and its
representatives (including but not limited to accounting, legal and financial
advisors) to visit and inspect the Company's properties, to examine its books
of account and records and to discuss the Company's affairs, finances and
accounts with its officers, all at such reasonable times as may be requested
by the Stockholder for the purpose of evaluating its investment in the
Company. In addition, in connection with any attempt by the Stockholder to
sell some or all of the shares of Common Stock it owns in the Company to a
potential purchaser (a "Potential Purchaser"), in a private transaction, the
Company shall permit the Potential Purchaser and its representatives
(including but not limited to accounting, legal and financial advisors) to
visit and inspect the Company's properties, to examine its books of account
and records and to discuss the Company's affairs, finances and accounts with
its officers, all at such reasonable times as may be requested by the
Stockholder and Potential Purchaser, provided that such Potential Purchaser
enters into a confidentiality agreement containing customary terms and
conditions for an agreement of that type; provided, that the Company shall not
be obligated under this Section 2.2 with respect to a direct competitor of the
Company.
 
  2.3 CONFIDENTIALITY. The Stockholder agrees to use, and to use its
reasonable best efforts to cause its employees and its authorized
representatives to use the same degree of care as the Stockholder uses to
protect its own confidential information and to keep confidential any
information furnished to it which the Company reasonably identifies as being
confidential or proprietary (so long as such information is not in the public
domain). The Stockholder further agrees not to use, and to cause its
representatives and employees not to use any such confidential information for
any purpose other than to evaluate the Stockholder's investment in the
Company.

March 5, 1998
 
Board of Directors
Paradigm Technology, Inc.
694 Tasman Drive
Milpitas, CA 95035
 
Gentlemen:
 
  You have requested our opinion as to the fairness, from a financial point of
view, to the shareholders of Paradigm Technology ("Paradigm"), Inc., for the
acquisition of IXYS, Inc., as of March 5, 1998 through the issuance of
405,059,347 new common shares of Paradigm.
 
  Alliant Partners, as part of its investment banking business, is regularly
engaged in the valuation of businesses and their securities in connection with
private placements, mergers and acquisitions, and corporate partnering
transactions. Alliant Partners has received fees from Paradigm for previous
engagements.
 
  In arriving at our opinion, we have reviewed financial and other information
that was publicly available or furnished to us by Paradigm and IXYS. We also
have reviewed certain internal financial reports and forecasts for Paradigm
and IXYS prepared by their respective managements and have held discussions
with members of the senior management of Paradigm and IXYS regarding the
historic and current business operations and future prospects, including their
expectations for certain strategic benefits of the transaction. We have also
noted that the Going Concern issues raised by Paradigm's auditors. In
addition, we have compared certain financial data of IXYS with those of
various other companies engaged in businesses we considered comparable and
whose securities are traded in public markets, reviewed the overall risks
presented by the business plan, reviewed prices paid in certain other similar
business transactions and conducted such other financial studies, analyses and
investigations as we deemed appropriate for purposes of this opinion.
 
  We have assumed, without independent verification, the accuracy,
completeness and fairness of all of the financial and other information
regarding IXYS and Paradigm that has been provided to us by them and their
representatives. We did not make any independent evaluation of IXYS' or
Paradigm's businesses nor did we review any of their corporate records.
 
  Based on the foregoing and such other factors as we deem relevant, we are of
the opinion as of the date hereof, that the IXYS company valuation of 95% of
the post transaction combined company shares through the issuance of
405,059,347 new common shares of Paradigm using an exchange ratio of 1.956020
is fair, from a financial point of view, to the Paradigm shareholders.
 
Sincerely Yours,
 
Alliant Partners

    described in the foregoing subparagraphs a., b. and c. of this
    paragraph.
 
    (3) In the event all of the stock of a subsidiary Delaware corporation
  party to a merger effected under sec. 253 of this title is not owned by the
  parent corporation immediately prior to the merger, appraisal rights shall
  be available for the shares of the subsidiary Delaware corporation.
 
  (c) Any corporation may provide in its certificate of incorporation that

of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.
 
  (d) Appraisal rights shall be perfected as follows:
 
    (1) If a proposed merger or consolidation for which appraisal rights are
  provided under this section is to be submitted for approval at a meeting of
  stockholders, the corporation, not less than 20 days prior to the meeting,
  shall notify each of its stockholders who was such on the record date for
  such meeting with respect to shares for which appraisal rights are
  available pursuant to subsections (b) or (c) hereof that appraisal rights
  are available for any or all of the shares of the constituent corporations,
  and shall include in such notice a copy of this section. Each stockholder
  electing to demand the appraisal of his shares shall deliver to the
  corporation, before the taking of the vote on the merger or consolidation,
  a written demand for appraisal of his shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of his shares. A proxy or vote against the merger or
  consolidation shall not constitute such a demand. A stockholder electing to
  take such action must do so by a separate written demand as herein
  provided. Within 10 days after the effective date of such merger or
  consolidation, the surviving or resulting corporation shall notify each
  stockholder of each constituent corporation who has complied with this
  subsection and has not voted in favor of or consented to the merger or
  consolidation of the date that the merger or consolidation has become
  effective; or
 
    (2) If the merger or consolidation was approved pursuant to (S)228 or
  (S)253 of this title, each constituent corporation, either before the
  effective date of the merger or consolidation or within ten days
  thereafter, shall notify each of the holders of any class or series of
  stock of such constituent corporation who are entitled to appraisal rights
  of the approval of the merger or consolidation and that appraisal rights
  are available for any or all shares of such class or series of stock of
  such constituent corporation, and shall include in such notice a copy of
  this section; provided that, if the notice is given on or after the
  effective date of the merger or consolidation, such notice shall be given
  by the surviving or resulting corporation to all such holders of any class
  or series of stock of a constituent corporation that are entitled to
  appraisal rights. Such notice may, and, if given on or after the effective
  date of the merger or consolidation, shall, also notify such stockholders
  of the effective date of the merger or consolidation. Any stockholder
  entitled to appraisal rights may, within 20 days after the date of mailing
  of such notice, demand in writing from the surviving or resulting
  corporation the appraisal of such holder's shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of such holder's shares. If such notice did not notify
  stockholders of the effective date of the merger or consolidation, either
  (i) each such constituent corporation shall send a second notice before the
  effective date of the merger or consolidation notifying each of the holders
  of any class or series of stock of such constituent corporation that are
  entitled to appraisal rights of the effective date of the merger or
  consolidation or (ii) the surviving or resulting corporation shall send
  such a second notice to all such holders on or within 10 days after such
  effective date; provided, however, that is such second notice is sent more
  than 20 days following the sending of the first notice, such second notice
  need only be sent to each stockholder who is entitled to appraisal rights
  and who has demanded appraisal of such holder's shares in accordance with
  this subsection. An affidavit of the secretary or assistant secretary or of
  the transfer agent of the corporation that is required to give either
  notice that such notice has been given shall, in the absence of fraud, be
  prima facie evidence of the facts stated therein. For purposes of
  determining the stockholders entitled to receive either notice, each
  constituent corporation may fix, in advance, a record date that shall be
  not more than 10 days prior to the date the notice is given, provided, that
  if the notice is given on or after the effective date of the merger or
  consolidation, the record date shall be such effective date. If no record
  date is fixed and the notice is given prior to the effective date, the
  record date shall be the close of business on the day next preceding the
  day on which the notice is given.

  (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied
with subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger
or consolidation, any stockholder shall have the right to withdraw his demand
for appraisal and to accept the terms offered upon the merger or
consolidation. Within 120 days after the effective date of the merger or
consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which
demands for appraisal have been received and the aggregate number of holders
of such shares. Such written statement shall be mailed to the stockholder
within 10 days after his written request for such a statement is received by
the surviving or resulting corporation or within 10 days after expiration of
the period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.
 
  (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.
 
  (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates
to submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.
 
  (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court
may, in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on
the list filed by the surviving or resulting corporation pursuant to
subsection (f) of this section and who has submitted his certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that he is not entitled to
appraisal rights under this section.
 
  (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of
the certificates representing such stock. The Court's decree may be enforced
as other decrees in the Court of
 
                                      C-3
<PAGE>
 
Chancery may be enforced, whether such surviving or resulting corporation be a
corporation of this State or of any state.
 
  (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
  (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection
(d) of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation);
provided, however, that if no petition for an appraisal shall be filed within
the time provided in subsection (e) of this section, or if such stockholder
shall deliver to the surviving or resulting corporation a written withdrawal
of his demand for an appraisal and an acceptance of the merger or
consolidation, either within 60 days after the effective date of the merger or
consolidation as provided in subsection (e) of this section or thereafter with
the written approval of the corporation, then the right of such stockholder to
an appraisal shall cease. Notwithstanding the foregoing, no appraisal
proceeding in the Court of Chancery shall be dismissed as to any stockholder
without the approval of the Court, and such approval may be conditioned upon
such terms as the Court deems just.
 
  (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation. (Last amended by Ch. 299, L.
'96, eff. 2-1-96 and Ch. 349, L. '96, eff. 7-1-96.)

  1. ESTABLISHMENT AND PURPOSE.
 
  The Plan was established in 1994 to offer selected employees and consultants
an opportunity to acquire a proprietary interest in the success of the
Company, or to increase such interest, by purchasing Shares of the Company's
Common Stock. The Plan provides for the grant of Options to purchase Shares.
Options granted under the Plan may include Nonstatutory Options as well as
ISOs intended to qualify under Code section 422.
   
  The Plan is being amended and restated effective as of the merger of
Paradigm Enterprises, Inc. with and into IXYS Corporation (the "Merger") to
reserve an additional 225,000 Shares (15,000 Shares after the reverse stock
splits occurring prior to and at the time of the Merger) for the grant of
options to Outside Directors and an additional 1,500,000 Shares (100,000
Shares after the reverse stock splits occurring prior to and at the time of
the Merger) for the grant of options to persons other than Outside Directors
and to increase the number of shares that can be made subject to options in
any fiscal year to 35,000 (after the reverse stock splits occurring prior to
and at the time of the Merger).

Optionees by the Committee. In addition, only individuals who are employed as
common-law employees by the Company or a Subsidiary shall be eligible for the

  the conclusion of each regular annual meeting of the Company's shareholders
  following the annual meeting at which they were appointed, each Outside
  Director who will continue serving as a member of the Board thereafter
  shall receive a Nonstatutory Option to purchase 3,125 Shares (after the
  reverse stock split occurring at the time of the Merger) (subject to
  adjustment under Section 8). All such Nonstatutory Options shall vest and
  become exercisable at the rate of 25% upon each one-year anniversary of the
  date the option is granted to the Outside Director.
 
    (iv) All Nonstatutory Options granted to an Outside Director under this
  Section 4(b) shall also become exercisable in full in the event of (A) the
  termination of such Outside Director's service because of death or Total
  and Permanent Disability or (B) a Change in Control of the Company.
 
    (v) Subject to (ii) above, the Exercise Price of all Nonstatutory Options
  granted to an Outside Director under this Section 4(b) shall be equal to
  100% of the Fair Market Value of a Share on the date of grant, payable in
  one of the forms described in Sections 7(a), (b) and (c).
 
    (vi) All Nonstatutory Options granted to an Outside Director under this
  Section 4(b) shall terminate on the earliest of (A) the 10th anniversary of
  the date of grant of such Nonstatutory Options, (B) the date 90 days after
  the termination of such Outside Director's service for any reason other
  than death, Total and Permanent Disability or voluntary retirement as an
  Outside Director at or after the age of 60, or (C) the date 12 months after
  the termination of such Outside Director's service because of death, Total
  and Permanent Disability or voluntary retirement as an Outside Director at
  or after the age of 60.
   
  (c) Limitation On Grants. No Employee shall be granted Options to purchase
in excess of 35,000 Shares during any fiscal year (after the reverse stock
splits occurring prior to and at the time of the Merger).     
 
  (d) Ten Percent Shareholders. An Employee who owns more than 10 percent of
the total combined voting power of all classes of outstanding stock of the
Company or any of its Subsidiaries shall not be eligible for the grant of an
ISO unless such grant satisfies the requirements of Code section 422(c)(5).
 
  (e) Attribution Rules. For purposes of Subsection (d) above, in determining
stock ownership, an Employee shall be deemed to own the stock owned, directly
or indirectly, by or for his brothers, sisters, spouse, ancestors and lineal
descendants. Stock owned, directly or indirectly, by or for a corporation,
partnership, estate or trust shall be deemed to be owned proportionately by or
for its shareholders, partners or beneficiaries.
 
  (f) Outstanding Stock. For purposes of Subsection (d) above, "outstanding
stock" shall include all stock actually issued and outstanding immediately
after the grant. "Outstanding stock" shall not include shares authorized for
issuance under outstanding options held by the Employee or by any other
person.
 
  5. STOCK SUBJECT TO PLAN.
   
  (a) Basic Limitation. Shares offered under the Plan shall be authorized but
unissued Shares or treasury Shares. The aggregate number of Shares which may
be issued under the Plan upon exercise of Options shall not exceed 234,800
Shares, of which 149,800 Shares are reserved for issuance prior to the Merger
and prior to the reverse stock splits occurring prior to and at the time of
the Merger (9,987 post-split Shares) and 100,000 additional post-split Shares
are reserved for issuance effective as of the Merger, for a total of 109,987
Shares after the reverse stock splits occurring prior to and at the time of
the Merger. Of that, an aggregate of 26,250 Shares are reserved for issuance
exclusively for grants to Outside Directors, as hereinafter defined, (the
"Director Shares"), of which 11,250 Shares are reserved for issuance prior to
the Merger and prior to the reverse stock splits occurring prior to and at the
time of the Merger (284 post-split Shares) and 15,000 additional post-split
Shares are reserved for issuance effective as of the Merger, for a total of
15,750 shares after the reverse stock splits occurring prior to and at the
time of the Merger. The Director Shares shall be reserved exclusively for
grants of Options to Outside Directors described in Section 4(b), and such
Option grants to Outside Directors     
 
                                      D-4
<PAGE>
 
   
described in Section 4(b) shall be limited to such Shares. On each January 1
for the remaining term of the Plan, and as of the closing of the Merger, the
aggregate number of Shares which may be issued under the Plan to individuals
other than Outside Directors shall be increased by a number of Shares equal to
3.0 percent of the total number of Shares of the Common Stock of the Company
outstanding at the end of the most recently effected increase in the number of
Shares available for issuance under the Plan. Any Shares that have been
reserved but not issued as Shares or Options during any calendar year shall
remain available for grant during any subsequent calendar year.
Notwithstanding the foregoing, no more than 234,800 Shares (15,654 Shares
after the reverse stock split occurring at the time of the Merger) shall be
available for the grant of ISOs for the remaining term of the Plan. The
aggregate number of Shares which may be issued under the Plan shall at all
times be subject to adjustment pursuant to Section 8. The number of Shares
which are subject to Options outstanding at any time under the Plan shall not
exceed the number of Shares which then remain available for issuance under the
Plan. The Company, during the term of the Plan, shall at all times reserve and
keep available sufficient Shares to satisfy the requirements of the Plan.     
 
  (b) Additional Shares. In the event that any outstanding Option for any
reason expires or is canceled or otherwise terminated, the Shares allocable to
the unexercised portion of such Option shall again be available for the
purposes of the Plan.
 
  6. TERMS AND CONDITIONS OF OPTIONS.
 
  (a) Stock Option Agreement. Each grant of an Option under the Plan shall be
evidenced by a Stock Option Agreement between the Optionee and the Company.
Such Option shall be subject to all applicable terms and conditions of the
Plan and may be subject to any other terms and conditions which are not
inconsistent with the Plan and which the Committee deems appropriate for
inclusion in a Stock Option Agreement. The provisions of the various Stock
Option Agreements entered into under the Plan need not be identical.
 
  (b) Number of Shares. Each Stock Option Agreement shall specify the number
of Shares that are subject to the Option and shall provide for the adjustment
of such number in accordance with Section 8. The Stock Option Agreement shall
also specify whether the Option is an ISO or a Nonstatutory Option.
 
  (c) Exercise Price. Each Stock Option Agreement shall specify the Exercise
Price. The Exercise Price of an ISO shall not be less than 100 percent of the
Fair Market Value of a Share on the date of grant, except as otherwise
provided in Section 4(d). Subject to the preceding sentence, the Exercise
Price under any Option shall be determined by the Committee at its sole
discretion. The Exercise Price shall be payable in one of the forms described
in Sections 7(a), (b) and (c).
 
  (d) Withholding Taxes. As a condition to the exercise of an Option, the
Optionee shall make such arrangements as the Committee may require for the
satisfaction of any federal, state or local withholding tax obligations that
may arise in connection with such exercise. The Optionee shall also make such
arrangements as the Committee may require for the satisfaction of any federal,
state or local withholding tax obligations that may arise in connection with
the disposition of Shares acquired by exercising an Option.
 
  (e) Exercisability and Term. Each Stock Option Agreement shall specify the
date when all or any installment of the Option is to become exercisable. The
Stock Option Agreement shall also specify the term of the Option. The term
shall not exceed 10 years from the date of grant, except as otherwise provided
in Section 4(d). Subject to the preceding three sentences, the Committee at
its sole discretion shall determine when all or any installment of an Option
is to become exercisable and when an Option is to expire.
 
  (f) Nontransferability. During an Optionee's lifetime, his Option(s) shall
be exercisable only by him and shall not be transferable, unless the Option
agreement otherwise provides. In the event of an Optionee's death, his
Option(s) shall not be transferable other than by will, beneficiary
designation or by the laws of descent and distribution.
 
  (g) Exercise of Options Upon Termination of Service. Each Stock Option
Agreement shall set forth the extent to which the Optionee shall have the
right to exercise the Option following termination of the Optionee's Service
with the Company and its Subsidiaries, and the right to exercise the Option of
any executors or
 
                                      D-5
<PAGE>
 
administrators of the Optionee's estate or any person who has acquired such
Option(s) directly from the Optionee by beneficiary designation, bequest or
inheritance. Such provisions shall be determined in the sole discretion of the
Committee, need not be uniform among all Options issued pursuant to the Plan,
and may reflect distinctions based on the reasons for termination of Service.
 
  (h) No Rights as a Stockholder. An Optionee, or a transferee of an Optionee,
shall have no rights as a stockholder with respect to any Shares covered by
his Option until the date of the issuance of a stock certificate for such
Shares. No adjustments shall be made, except as provided in Section 8.
 
  (i) Modification, Extension and Renewal of Options. Within the limitations
of the Plan, the Committee may cancel, modify, extend or renew outstanding
Options or may accept the cancellation of outstanding Options (to the extent
not previously exercised) in return for the grant of new Options at the same
or a different price. The foregoing notwithstanding, no modification of an
Option shall, without the consent of the Optionee, impair his rights or
increase his obligations under such Option.
 
  (j) Restrictions on Transfer of Shares. Any Shares issued upon exercise of
an Option shall be subject to such special forfeiture conditions, rights of
repurchase, rights of first refusal and other transfer restrictions as the
Committee may determine. Such restrictions shall be set forth in the
applicable Stock Option Agreement and shall apply in addition to any general
restrictions that may apply to all holders of Shares.
 
  7. PAYMENT FOR SHARES.
 
  (a) General Rule. The entire Exercise Price of Shares issued under the Plan
shall be payable in lawful money of the United States of America at the time
when such options are exercised, except as provided in Subsections (b) and (c)
below.
 
  (b) Surrender of Stock. To the extent that a Stock Option Agreement so
provides, payment may be made all or in part with Shares which have already
been owned by the Optionee or his representative for more than the maximum
number of months required by the Committee and which are surrendered to the
Company in good form for transfer. Such Shares shall be valued at their Fair
Market Value on the date when the new Shares are purchased under the Plan.
 
  (c) Cashless Exercise. To the extent that a Stock Option Agreement so
provides, payment may be made all or in part by delivery (on a form prescribed
by the Committee) of an irrevocable direction to a securities broker to sell
Shares and to deliver all or part of the sale proceeds to the Company in
payment of the aggregate Exercise Price.
 
  8. ADJUSTMENT OF SHARES.
 
  (a) General. In the event of a subdivision of the outstanding Stock, a
declaration of a dividend payable in Shares, a declaration of a dividend
payable in a form other than Shares in an amount that has a material effect on
the value of Shares, a combination or consolidation of the outstanding Stock
(by reclassification or otherwise) into a lesser number of Shares, a
recapitalization or a similar occurrence, the Committee shall make appropriate
adjustments in one or more of (i) the number of Shares available for future
grants under Section 5, (ii) the number of Shares covered by each outstanding
Option or (iii) the Exercise Price under each outstanding Option.
 
  (b) Reorganizations. In the event that the Company is a party to a merger or
other reorganization, outstanding Options shall be subject to the agreement of
merger or reorganization. Such agreement may provide for the assumption of
outstanding Options by the surviving corporation or its parent or for their
continuation by the Company (if the Company is a surviving corporation);
provided, however, that if assumption or continuation of the outstanding
Options is not provided by such agreement then the Committee shall have the
option of offering the payment of a cash settlement equal to the difference
between the amount to be paid for one Share under such agreement and the
Exercise Price, in all cases without the Optionees' consent.
 
 
                                      D-6
<PAGE>
 
  (c) Reservation of Rights. Except as provided in this Section 8, an Optionee
shall have no rights by reason of any subdivision or consolidation of shares
of stock of any class, the payment of any dividend or any other increase or
decrease in the number of shares of stock of any class. Any issue by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall not affect, and no adjustment by reason thereof
shall be made with respect to, the number or Exercise Price of Shares subject
to an Option. The grant of an Option pursuant to the Plan shall not affect in
any way the right or power of the Company to make adjustments,
reclassifications, reorganizations or changes of its capital or business
structure, to merge or consolidate or to dissolve, liquidate, sell or transfer
all or any part of its business or assets.
 
  9. LEGAL AND REGULATORY REQUIREMENTS.
 
  Shares shall not be issued under the Plan unless the issuance and delivery
of such Shares complies with (or is exempt from) all applicable requirements
of law, including (without limitation) the Securities Act of 1933, as amended,
the rules and regulations promulgated thereunder, state securities laws and
regulations and the regulations of any stock exchange on which the Company's
securities may then be listed, and the Company has obtained the approval or
favorable ruling from any governmental agency which the Company determines is
necessary or advisable.
 
  10. NO EMPLOYMENT RIGHTS.
 
  No provision of the Plan, nor any Option granted under the Plan, shall be
construed to give any person any right to become, to be treated as, or to
remain an Employee. The Company and its Subsidiaries reserve the right to
terminate any person's Service at any time and for any reason.
 
  11. DURATION AND AMENDMENTS.
 
  (a) Term of the Plan. The amended and restated Plan, as set forth herein,
shall become effective as of the date first set forth above, subject to the
approval of the Company's stockholders. In the event that the stockholders
fail to approve this amended and restated Plan within 12 months of its
adoption by the Board of Directors, the Plan as in effect prior to this
amendment and restatement shall continue in effect, and any additional Option
grants shall be deemed made pursuant to the terms of the Plan as in effect
prior to this amendment and restatement. The Plan shall terminate
automatically 10 years after its original adoption by the Board of Directors
and may be terminated on any earlier date pursuant to Subsection (b) below.
 
  (b) Right to Amend or Terminate the Plan. The Board of Directors may amend
the Plan at any time and from time to time except that the provisions of
Section 4(b) relating to the amount, price and timing of the Option grants to
Outside Directors shall not be amended more than once in any six-month period
after the Plan becomes effective, except as may be required by the Code or
ERISA. Rights and obligations under any Option granted before amendment of the
Plan shall not be materially altered, or impaired adversely, by such
amendment, except with consent of the person to whom the Option was granted.
An amendment of the Plan shall be subject to the approval of the Company's
stockholders only to the extent required by applicable laws, regulations or
rules.
 
  (c) Effect of Amendment or Termination. No Shares shall be issued or sold
under the Plan after the termination thereof, except upon exercise of an
Option granted prior to such termination. The termination of the Plan, or any
amendment thereof, shall not affect any Share previously issued or any Option
previously granted under the Plan.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 ("Section 145") of the DGCL provides generally and in pertinent
part that a Delaware corporation may indemnify its directors, officers,
employees and agents against expenses (including attorneys' fees), judgments,
fines and settlements actually and reasonably incurred by them in connection
with any civil, criminal, administrative or investigative action, suit or
proceeding (except actions by or in the right of the corporation), if, they
acted in good faith and in a manner they reasonably believed to be in, or not
opposed to, the best interests of the corporation, and, with respect to any
criminal suit or proceeding, they had no reasonable cause to believe their
conduct was unlawful. Section 145 further provides that, in connection with
the defense or settlement of any action by or in the right of the corporation,
a Delaware corporation may indemnify its directors, officers, employees and
agents against expenses actually and reasonably incurred by them if they acted
in good faith and in a manner they reasonably believed to be in, or not
opposed to, the best interests of the corporation, except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation,
absent a determination by a court that such indemnity is proper. Section 145
further permits a Delaware corporation to grant its directors, officers,
employees and agents additional rights of indemnification through bylaw
provisions and otherwise.
 
  Section 145 further permits a Delaware corporation to purchase and maintain
insurance on behalf of any persons who are or were directors, officers,
employees or agents of the corporation, or are or were serving at the request
of the corporation as directors, officers, employees or agents of another
corporation, partnership, joint venture, trust or other enterprise against any
liability asserted against them and incurred by them in any such capacity, or
arising out of their status as such, whether or not the corporation would have
the power to indemnify them against such liability under the other provisions
of Section 145.
 
  Section 102(b)(7) of the DGCL provides that a certificate of incorporation
may contain a provision eliminating or limiting the personal liability of a
director to the corporation or its stockholders for monetary damages for
breach of fiduciary duty as a director, provided that such provision shall not
eliminate or limit the liability of a director (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 DGCL (relating to
liability for unauthorized acquisitions or redemptions of, or dividends on,
capital stock) or (iv) for any transaction from which the director derived an
improper personal benefit.
 
  The Restated Certificate of Incorporation of Paradigm provides for the
indemnification of its directors and officers to the fullest extent provided
by the DGCL.
 
  In addition, Article VII of Paradigm's Restated Certificate of Incorporation
provides, in part, as follows:
 
  "To the fullest extent permitted by the Delaware General Corporation Law, a
  director of the Corporation shall not be personally liable to the
  Corporation or its stockholders for monetary damages for beach of fiduciary
  duty as a director, except for liability (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 Delaware
  General Corporation Law, or (iv) for any transaction from which the
  director derived an improper personal benefit."

ITEM 22. UNDERTAKINGS.
 
  The undersigned registrant hereby undertakes:
 
    (1) To file, during any period in which offers or sales are being made, a
  post-effective amendment to this registration statement:
 
      (i) To include any prospectus required by section 10(a)(3) of the
    Securities Act of 1933;
 
      (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in the registration statement. Notwithstanding the foregoing, any
    increase or decrease in volume of securities offered (if the total
    dollar value of securities offered would not exceed that which was
    registered) and any deviation from the low or high end of the estimated
    maximum offering range may be reflected in the form of prospectus filed
    with the Commission pursuant to Rule 424(b) if, in the aggregate, the
    changes in volume and price represent no more than a 20% change in the
    maximum aggregate offering price set forth in the "Calculation of
    Registration Fee" table in the effective registration statement.
 
      (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the registration statement or
    any material change to such information in the registration statement.
 
    (2) That, for the purpose of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
    (3) To remove from registration by means of post-effective amendment any
  of the securities being registered which remain unsold at the termination
  of the offering.
 
    (4) That prior to any public reoffering of the securities registered
  hereunder through the use of a prospectus which is a part of this
  registration statement, by any person or party who is deemed to be an
  underwriter within the meaning of Rule 145(c), the issuer undertakes that
  such reoffering prospectus will contain the information called for by the
  applicable registration form with respect to reofferings by persons who may
  be deemed underwriters, in addition to the information called for by the
  other items of the applicable form.
 
    (5) That every prospectus (i) that is filed pursuant to paragraph (4)
  immediately preceding, or (ii) that purports to meet the requirements of
  section 10(a)(3) of the Act and is used in connection with an offering of
  securities subject to Rule 415, will be filed as a part of an amendment to
  the registration statement and will not be used until such amendment is
  effective, and that, for purposes of determining any liability under the
  Securities Act of 1933, each such post-effective amendment shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the
registrant in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
it is against public policy as expressed in the Act and will be governed by
the final adjudication of such issue.

Paradigm Technology, Inc.
694 Tasman Drive
Milpitas, CA 95035
 
Ladies and Gentlemen:
   
  This opinion is being delivered to you in connection with the filing with
the Securities and Exchange Commission of a Registration Statement on Form S-4
(the "Registration Statement") through which Paradigm Technology, Inc.
("Paradigm"), a Delaware corporation, is registering under the Securities Act
of 1933, as amended, shares of its common stock, par value $0.01 (the
"Paradigm Common Stock") and in which is described the proposed (i) plan of
reorganization that would result in the merger (the "Merger") of Paradigm
Enterprises, Inc. ("Merger Subsidiary"), a Delaware corporation and a wholly
owned subsidiary of Paradigm, with and into IXYS Corporation, a Delaware
corporation ("IXYS"), and (ii) subsequent change by Paradigm of its name to
IXYS Corporation. The proposed plan (the "Plan") is set forth in the Agreement
and Plan of Merger and Reorganization (the "Merger Agreement") dated as of
March 6, 1998, as amended on April 10, 1998, May 29, 1998 and July 1, 1998,
among Paradigm, Merger Subsidiary and IXYS. We understand, and the opinions
rendered herein assume, that the facts surrounding the Merger are and will be
as follows:     
 
  Paradigm designs and markets high speed, high density static random access
memory semiconductor devices to meet the needs of advanced telecommunications
devices, networks, workstations, high performance PCs, advanced modems and
complex military and aerospace applications. The authorized capital stock of
Paradigm consists of 25 million shares of Paradigm Common Stock and 5 million
shares of preferred stock, $0.01 par value (the "Preferred Stock"); as of the
date of the Merger Agreement, there were issued and outstanding 14,881,039
shares of Paradigm Common Stock, 30 shares of Preferred Stock designated
Series A, 68 shares of Preferred Stock designated Series B and 85 shares of
Preferred Stock designated Series C. Paradigm Common Stock is listed on the
Nasdaq SmallCap Market.
 
  The authorized capital stock of Merger Subsidiary consists of 1,000 shares
of common stock, par value $0.01, 100 of which are issued and outstanding and
owned by Paradigm.
 
  IXYS designs, develops and markets a broad spectrum of power semiconductors
used primarily in controlling energy in motor drives, power conversion
(including uninterruptible power supplies and switch mode power supplies) and
medical devices. The authorized capital stock of IXYS consists of 250 million
shares of IXYS Common Stock and 116 million shares of preferred stock, $0.001
par value (41.2 million of which have been designated "Series A Preferred
Stock" and 74,382,633 of which have been designated "Series B Preferred
Stock"); the IXYS Common Stock, Series A Preferred Stock and Series B
Preferred Stock are referred to herein collectively as the "IXYS Capital
Stock." As of the date of the Merger Agreement, there were issued and
outstanding 72,557,485 shares of Paradigm Common Stock, 37,026,730 shares of
Series A Preferred Stock and 74,382,633 shares of Series B Preferred Stock.
 
  The managements of Paradigm and IXYS have determined that the proposed
Merger will be in the best interests of their companies and stockholders.
Paradigm management believes that Paradigm will benefit from the potential to
develop with IXYS new products based on the two companies' existing
technologies, from increased insulation from adverse market conditions for
Paradigm's existing products and from access to current
<PAGE>
 
IXYS customers not already Paradigm customers. IXYS management believes IXYS
will benefit from the combination of the two companies' technologies by being
able to respond more effectively to technological change in and continuing
emergence of power management control products and from an expanded customer
base.
   
  Under the Plan, prior to the Merger (i) there will be a 15-for-one reverse
stock split of the Paradigm Common Stock, (ii) the number of authorized shares
of Paradigm Common Stock will be increased, (iii) the Preferred Stock will be
converted into shares of Paradigm Common Stock and (iv) the Paradigm
stockholders will approve the change of Paradigm's name to IXYS Corporation.
Also under the Plan, Merger Subsidiary will merge with and into IXYS in
accordance with Delaware law. Upon the effectiveness of the Merger (the
"Effective Time"), the following will occur:     
 
    1. IXYS will be the surviving corporation, and the separate existence of
  Merger Subsidiary will cease.
 
    2. Each issued and outstanding share of capital stock of Merger
  Subsidiary will be converted into one share of common stock of IXYS, the
  corporation surviving the Merger.
 
    3. Each share of IXYS Capital Stock which is outstanding immediately
  prior to the Merger, except for shares held by dissenters perfecting their
  appraisal rights, will be converted into shares of Paradigm Common Stock at
  the "Exchange Ratio." The Exchange Ratio will be established such that the
  former holders of IXYS Capital Stock will hold Paradigm Common Stock
  representing the greater of (i) 95 percent of the outstanding Paradigm
  Common Stock on a fully diluted basis or (ii) a valuation of $150 million.
 
    4. No fractional shares will be issued to holders of IXYS Capital Stock;
  each holder of IXYS Capital Stock otherwise entitled to a fractional
  interest in a share of Paradigm Common Stock will receive an amount of cash
  equal to the product obtained by multiplying such fractional share interest
  by the closing price of Paradigm Common Stock as reported by the Nasdaq
  SmallCap Market on the day of the Effective Time.
 
    5. Holders of shares of IXYS Capital Stock perfecting their dissenters'
  rights will be entitled to receive cash.
 
    6. Each outstanding option or warrant to acquire IXYS Capital Stock which
  has not been exercised by its holder prior to the Merger will be converted
  into an option or warrant to acquire, at a price per share equal to the
  exercise price specified in such option or warrant divided by the Exchange
  Ratio (with the resulting exercise price rounded up to the nearest
  hundredth of a cent), that number of shares of Paradigm Common Stock equal
  to the product of the number of shares of IXYS Capital Stock formerly
  subject to the option or warrant and the Exchange Ratio (with the resulting
  number of shares rounded down to the nearest whole share).
 
  For purposes of rendering this opinion we have examined and are relying upon
(without any independent investigation or review) the truth, correctness and
completeness at all relevant times of the statements, covenants,
representations and warranties contained in the Merger Agreement, letters
dated June 26, 1998 delivered to us by Paradigm, Merger Subsidiary and IXYS
containing their respective tax-related representations (the "Tax
Representation Letters") and such other instruments and documents as we have
deemed necessary.
 
  Further, for purposes of rendering this opinion we have made the following
assumptions (without any independent investigation or review):
 
    (a) Original documents submitted to us (including signatures) are
  authentic, documents submitted to us as copies conform to the original
  documents and all such documents either have been or will be by the
  Effective Time duly and validly executed and delivered where such
  execution and delivery are prerequisites to effectiveness;
 
    (b) All representations, warranties and statements made or agreed to
  by Paradigm, Merger Subsidiary and IXYS and by their respective
  managements, officers and directors in connection with the Merger,
  including but not limited to those set forth in the Merger Agreement
  and the Tax Representation Letters are true, correct and complete at
  all relevant time;
 
                                       2
<PAGE>
 
    (c) All covenants contained in the Merger Agreement and Tax
  Representation Letters will be performed without waiver or breach of
  any material provision; and
 
    (d) Any representation or statement made "to the best knowledge" or
  similarly qualified is correct without such qualification.
 
  Based solely on the information, understandings and assumptions and subject
to the limitations contained herein, we are of the opinion that the Merger
will constitute a reorganization within the meaning of Internal Revenue Code
section 368(a)(1). Accordingly, and again based solely on the information,
understandings and assumptions and subject to the limitations contained
herein, we are further of the opinion that, for federal income tax purposes:
 
    (i) no gain or loss will be recognized by holders of IXYS Capital Stock
  who exchange their IXYS Capital Stock for Paradigm Common Stock pursuant to
  the Merger, except with respect to cash received in lieu of fractional
  shares;
 
    (ii) the aggregate tax basis of Paradigm Common Stock received as a
  result of the Merger will be the same as the stockholder's aggregate tax
  basis in the IXYS Capital Stock surrendered in the exchange (reduced by any
  basis allocable to fractional shares for which cash is received);
 
    (iii) the holding period of Paradigm Common Stock received in exchange
  for IXYS Capital Stock in the Merger will include the holding period of
  such IXYS Capital Stock, provided the shares of IXYS Capital Stock are
  capital assets in the hands of the holder thereof at the Effective Time;
 
    (iv) a holder of IXYS Capital Stock receiving cash in the Merger in lieu
  of a fractional interest in Paradigm Common Stock will be treated as if
  such holder actually received such fractional share interest which was
  subsequently redeemed by Paradigm, resulting in the recognition of gain or
  loss (capital gain or loss if the IXYS Capital Stock giving rise to such
  fractional interest is held as a capital asset within the meaning of
  Section 1221 of the Code), measured by the difference between the amount of
  cash received and the basis of the IXYS Capital Stock allocable to such
  fractional interest; and
 
    (v) a holder of IXYS Capital Stock exercising appraisal rights and
  receiving a cash payment therefor will generally recognize gain or loss
  (capital gain or loss if such IXYS Capital Stock is held as a capital asset
  within the meaning of Section 1221 of the Code) measured by the difference
  between the amount of cash received and the basis of such IXYS Capital
  Stock, as long as such payment neither is "essentially equivalent to a
  dividend" within the meaning of Section 302 of the Code nor has the effect
  of distribution of a dividend within the meaning of Section 356(a)(2) of
  the Code.
 
  In addition, in our opinion the discussion under the caption "The Merger
Proposal and the Issuance Proposal--Material Federal Income Tax Consequences"
in the Registration Statement,insofar as it relates to statements of law and
legal conclusions, is correct in all material respects.
 
  The opinions expressed herein are based upon laws, judicial decisions and
administrative regulations, rulings and practice, all as in effect on the date
hereof and all of which are subject to change, either on a prospective or
retroactive basis. New developments in any such administrative matters, court
decisions, legislative changes, or changes in the facts, assumptions or other
information upon which our opinions are based may have an adverse effect on
the legal or tax consequences described herein, and we do not accept any
responsibility for updating or revising our opinions in consequence of any
such new development or changes. No opinion is expressed about the federal tax
treatment of the proposed Merger under other provisions of the Internal
Revenue Code, about the federal income tax treatment of any conditions
existing at the time of, or effects resulting from, the proposed Merger that
are not specifically covered by the above opinions, nor about tax effects of
the proposed Merger other than the federal income tax treatment thereof. In
particular, but not by way of limitation, we express no opinion regarding the
tax consequences of the proposed Merger (including the opinions set forth
above) that may be applicable to a particular stockholder or securityholder of
IXYS in light of personal circumstances or to certain types of stockholders or
securityholders subject to special treatment under the federal income tax laws
such as life insurance companies, dealers in securities, taxpayers subject to
the alternative minimum tax, banks, tax-exempt organizations, non-United
States persons and stockholders who acquired their IXYS shares pursuant to the
exercise of options or otherwise as compensation or who hold their IXYS shares
as part of a straddle or risk reduction transaction.

                      [LETTERHEAD OF COOLEY GODWARD LLP]
   
July 6, 1998     
 
IXYS Corporation
3540 Bassett Street
Santa Clara, CA 95054-2704
 
Ladies and Gentlemen:
   
  This opinion is being delivered to you in connection with the Form S-4
Registration Statement (the "Registration Statement") filed pursuant to the
Agreement and Plan of Merger and Reorganization dated as of March 6, 1998, as
amended on April 10, 1998, May 29, 1998 and July 1, 1998 (the "Reorganization
Agreement") by and among Paradigm Technology, Inc., a Delaware corporation
("Parent"), Paradigm Enterprises, Inc., a Delaware corporation and wholly
owned subsidiary of Parent ("Merger Sub"), and IXYS Corporation, a Delaware
corporation (the "Company").     
 
  Except as otherwise provided, capitalized terms used but not defined herein
shall have the meanings set forth in the Reorganization Agreement. All section
references, unless otherwise indicated, are to the Internal Revenue Code of
1986, as amended (the "Code").
 
  We have acted as counsel to the Company in connection with the Merger. As
such, and for the purpose of rendering this opinion, we have examined, and are
relying upon (without any independent investigation or review thereof) the
truth and accuracy, at all relevant times, of the statements, covenants,
representations and warranties contained in, the following documents
(including all exhibits and schedules attached thereto):
 
    (a) the Reorganization Agreement;
 
    (b) those certain tax representation letters dated June 26, 1998
  delivered to us by Parent, Merger Sub and the Company containing certain
  representations of Parent, Merger Sub and the Company (the "Tax
  Representation Letters"); and
 
    (c) such other instruments and documents related to the formation,
  organization and operation of Parent, Merger Sub and the Company and
  related to the consummation of the Merger and the other transactions
  contemplated by the Reorganization Agreement as we have deemed necessary or
  appropriate.
 
  In connection with rendering this opinion, we have assumed (without any
independent investigation or review thereof) that:
 
    (a) Original documents submitted to us (including signatures thereto) are
  authentic, documents submitted to us as copies conform to the original
  documents, and that all such documents have been (or
<PAGE>
 
  will be by the Effective Time) duly and validly executed and delivered
  where due execution and delivery are a prerequisite to the effectiveness
  thereof;
 
    (b) All representations, warranties and statements made or agreed to by
  Parent, Merger Sub and the Company, their managements, employees, officers
  and directors in connection with the Merger, including, but not limited to,
  those set forth in the Reorganization Agreement (including the exhibits
  thereto) and the Tax Representation Letters are true and accurate at all
  relevant times;
 
    (c) All covenants contained in the Reorganization Agreement (including
  exhibits thereto) and the Tax Representation Letters are performed without
  waiver or breach of any material provision thereof; and
 
    (d) Any representation or statement made "to the best of knowledge" or
  similarly qualified is correct without such qualification.
 
  Based on our examination of the foregoing items and subject to the
limitations, qualifications, assumptions and caveats set forth herein, we are
of the opinion that, for federal income tax purposes, the Merger will be a
reorganization within the meaning of Section 368(a)(1) of the Code and the
following federal income tax consequences will result:
 
  . No gain or loss will be recognized for federal income tax purposes by the
    holders of Company Capital Stock upon the receipt of Parent Common Stock
    solely in exchange for such Company Capital Stock in the Merger (except
    to the extent, if any, that cash is received in lieu of fractional
    shares).
 
  . The aggregate tax basis of the Parent Common Stock so received by Company
    stockholders in the Merger (including any fractional shares of Parent
    Common Stock not actually received) will be the same as the aggregate tax
    basis of the Company Capital Stock surrendered in exchange therefor.
 
  . The holding period of the Parent Common Stock so received by each Company
    stockholder in the Merger will include the holding period of the shares
    of Company Capital Stock surrendered in exchange therefor.
 
  . Cash payments received by holders of Company Capital Stock in lieu of
    fractional shares of Parent Common Stock will be treated as if such
    fractional shares had been issued in the Merger and then redeemed by
    Parent. A Company stockholder receiving such cash will recognize gain or
    loss upon such payment, measured by the difference (if any) between the
    amount of cash received and the basis allocated to such fractional share.
    The gain or loss should be capital gain or loss, provided that each such
    fractional share of Parent Common Stock was held as a capital asset at
    the Effective Time of the Merger.
 
  . A holder of Company Capital Stock who exercises appraisal rights with
    respect to a share of Company Capital Stock and receives a cash payment
    for such share generally should recognize capital gain or loss (if such
    share was held as a capital asset at the Effective Time of the Merger)
    measured by the difference between the stockholder's basis in such share
    and the amount of cash received, provided that such payment is not
    "essentially equivalent to a dividend" within the meaning of Section 302
    of the Code nor has the effect of a distribution of a dividend within the
    meaning of Section 356(a)(2) of the Code after giving effect to the
    constructive ownership rules of the Code (collectively, a "Dividend
    Equivalent Transaction"). A sale of shares pursuant to an exercise of
    appraisal rights generally will not be a Dividend Equivalent Transaction
    if, as a result of such exercise, the stockholder exercising the
    appraisal rights owns no shares of capital stock of Parent (either
    actually or constructively within the meaning of Section 318 of the Code)
    immediately after the Merger.
 
  In addition to your request for our opinion on this specific matter of
federal income tax law, you have asked us to review the discussion of federal
income tax issues contained in the Registration Statement. We have reviewed
the discussion entitled "Material Federal Income Tax Consequences" contained
in the Registration Statement and believe that, insofar as it relates to
statements of law and legal conclusions, is correct in all material respects.
 
  We consent to the reference to our firm under the captions "Material Federal
Income Tax Consequences" and "Legal Opinions" in the Proxy Statement included
in the Registration Statement and to the filing of this opinion as an exhibit
to the Proxy Statement and to the Registration Statement.

  This opinion does not address the various state, local or foreign tax
consequences that may result from the Merger or the other transactions
contemplated by the Reorganization Agreement. In addition, no opinion is
expressed as to any federal income tax consequence of the Merger or the other
transactions contemplated by the Reorganization Agreement except as
specifically set forth herein, and this opinion may not be relied upon except
with respect to the consequences specifically discussed herein. No opinion is
expressed as to the federal income tax treatment that may be relevant to a
particular investor in light of personal circumstances or to certain types of
investors subject to special treatment under the federal income tax laws (for
example, life insurance companies, dealers in securities, taxpayers subject to
the alternative minimum tax, banks, tax-exempt organizations, non-United
States persons, and stockholders who acquired their shares of Company Capital
Stock pursuant to the exercise of options or otherwise as compensation or who
hold their Company Capital Stock as part of a straddle or risk reduction
transaction).
 
  No opinion is expressed as to any transaction other than the Merger as
described in the Reorganization Agreement, or as to any other transaction
whatsoever, including the Merger, if all of the transactions described in the
Reorganization Agreement are not consummated in accordance with the terms of
the Reorganization Agreement and without waiver of any material provision
thereof. To the extent that any of the representations, warranties, statements
and assumptions material to our opinion and upon which we have relied are not
accurate and complete in all material respects at all relevant times, our
opinion would be adversely affected and should not be relied upon.
 
  This opinion only represents our best judgment as to the federal income tax
consequences of the Merger and is not binding on the Internal Revenue Service
or any court of law, tribunal, administrative agency or other governmental
body. The conclusions are based on the Code, existing judicial decisions,
administration regulations and published rulings. No assurance can be given
that future legislative, judicial or administrative changes or interpretations
would not adversely affect the accuracy of the conclusions stated herein.
Nevertheless, by rendering this opinion, we undertake no responsibility to
advise you of any new developments in the application or interpretation of the

Paradigm Technology, Inc.

Milpitas, CA 95035
 
Ladies and Gentlemen:
   
  This opinion is being delivered to you in connection with the filing with
the Securities and Exchange Commission of a Registration Statement on Form S-4
(the "Registration Statement") through which Paradigm Technology, Inc.
("Paradigm"), a Delaware corporation, is, among other things, soliciting the
approval of its stockholders of a proposed 15-for-one reverse stock split (the
"Reverse Stock Split") of its common stock, par value $0.01 (the "Paradigm
Common Stock"). If so approved, the Reverse Stock Split, which is described in
more detail under the caption "The Reverse Stock Split Proposal" in the
Registration Statement, will result in every 15 shares of Paradigm Common
Stock being converted into one share of Paradigm Common Stock with any
fractional share interest being rounded up to the nearest whole share.
Capitalized terms used but not otherwise defined herein shall have the
meanings ascribed to them in the Registration Statement.     
 
  Assuming that the Reverse Stock Split is carried out in accordance with its
description in the Registration Statement under the caption "The Reverse Stock
Split Proposal," we are of the opinion that the Reverse Stock Split will
constitute a reorganization within the meaning of Internal Revenue Code
section 368(a)(1) and that, accordingly, for federal income tax purposes:
 
    (i) neither Paradigm nor the holders of Paradigm Common Stock will
  recognize any gain or loss upon the exchange of Paradigm Common Stock for a
  reduced number of shares of Paradigm Common Stock;
 
    (ii) holders of Paradigm Preferred Stock will recognize no income, gain
  or loss as a result of the changes to the conversion ratios for such stock
  incident to the Reverse Stock Split;
 
    (iii) the aggregate tax basis for computing gain or loss of Paradigm
  Common Stock to be issued as a result of the Reverse Stock Split will be
  the same as the stockholder's aggregate tax basis in the Paradigm Common
  Stock surrendered in exchange therefor; and
 
    (iv) the holding period of Paradigm Common stock to be issued as a result
  of the Reverse Stock Split will include the holding period of the Paradigm
  Common Stock surrendered in exchange therefor, provided the shares of
  Paradigm Common Stock are capital assets in the hands of the holder thereof
  on the Split Effective Date.
 
  In addition, in our opinion the discussion under the caption "The Reverse
Stock Split Proposal--Material Federal Income Tax Consequences" in the
Registration Statement, insofar as it relates to statements of law and legal
conclusions, is correct in all material respects.
 
  The opinions expressed herein are based upon laws, judicial decisions and
administrative regulations, rulings and practice, all as in effect on the date
hereof and all of which are subject to change, either on a prospective or
retroactive basis. New developments in any such administrative matters, court
decisions, legislative changes, or changes in the facts, assumptions or other
information upon which our opinions are based may have an adverse effect on
the legal or tax consequences described herein, and we do not accept any
responsibility for updating or revising our opinions in consequence of any
such new development or changes.

No opinion is expressed about the federal tax treatment of the proposed
Reverse Stock Split under other provisions of the Internal Revenue Code, about
the federal income tax treatment of any conditions existing at the time of, or
effects resulting from, the proposed Reverse Stock Split that are not
specifically covered by the above opinions, nor about tax effects of the
proposed Reverse Stock Split other than the federal income tax treatment
thereof. In particular, but not by way of limitation, we express no opinion
regarding the tax consequences of the proposed Reverse Stock Split (including
the opinions set forth above) that may be applicable to a particular
stockholder or securityholder of Paradigm in light of personal circumstances
or to certain types of stockholders or securityholders subject to special
treatment under the federal income tax laws such as life insurance companies,
dealers in securities, taxpayers subject to the alternative minimum tax,
banks, tax-exempt organizations, non-United States persons and stockholders
who acquired their Paradigm shares pursuant to the exercise of options or
otherwise as compensation or who hold their Paradigm shares as part of a
straddle or risk reduction transaction.
 
  This opinion is intended solely for the purpose of including this opinion as
an exhibit to the Registration Statement. It may not be relied upon for any
other purpose by any person or entity, other than Paradigm and the Paradigm
stockholders, and may not be made available to any other person or entity
without our written consent. We hereby consent to the filing of this opinion
as an exhibit to the Registration Statement and further consent to the use of
our name under the caption "The Reverse Stock Split Proposal--Material Federal
Income Tax Consequences" in the Registration Statement.

                         EXECUTIVE EMPLOYMENT AGREEMENT
                         ------------------------------

This First Amended Executive Employment Agreement (the "Agreement") is entered
into by and between IXYS Corporation (the "Company"), a Delaware corporation,
and Nathan Zommer ("Executive"), effective as of July 1, 1998 (the
    -------------                                                     
"Effective Date").

                              W I T N E S S E T H

WHEREAS, the Company and Executive are parties to that certain Executive
Employment Agreement effective as of January 1, 1995, which is modified and

employment of Executive under mutually satisfactory terms and conditions, and
the Executive desires to be employed by the Company, under the terms and
conditions herein.

NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as
follows:

1.  EMPLOYMENT BY THE COMPANY.  The Company hereby employs Executive to render
full-time services to the Company as its Chief Executive Officer.  Executive
shall have responsibilities, duties and authorities that are customarily
associated with such position, and such duties that are assigned by the
Company's Board of Directors (the "Board").

2.  COMPENSATION, VACATION AND BENEFITS.

    2.1  The Company agrees to pay Executive an annual base salary in the 
    amount of $285,000, payable every two weeks. In addition, the Company agrees
    to pay Executive an annual bonus equal to forty percent (40%) of Executive's
    annual base salary. The executive's performance, and his base salary and
    bonus arrangement will be reviewed by the Board from time to time.

    2.2  Executive's paychecks will be distributed pursuant to ordinary business
    practice, and shall be subject to ordinary payroll deductions and tax
    withholdings. The Company also agrees to provide Executive with benefits
    consistent with Company policy for senior executives. Details about these
    benefits are set forth in the employee handbook and summary plan
    descriptions, copies of which have been provided to Executive.

    2.3  In addition to the benefits provided to Executive pursuant to 
    subsections 2.1 and 2.2 hereof, the Company shall:

         (a)  pay, or reimburse Executive, for all reasonable costs of a yearly 
         medical exam of Executive by a physician of his choice;

         amount of $1,000,000 on the life of the Executive payable to such
         beneficiary or beneficiaries as Executive may designate from time to
         time;

         (c)  pay, or reimburse Executive, for the services of a personal tax 
         and/or investment advisor, not to exceed $1,000 per year; and

         (d)  provide Executive with a car of such make and model as Executive 
         and Board shall agree is commensurate with Executive's position with
         the Company, including insurance for such car and reasonable
         maintenance thereof; provided, however, that Executive shall at all
         times (i) comply with all policies of the Company from time to time in
         effect with respect to the maintenance and operation of motor vehicles,
         and (ii) maintain a valid driver's license.

3.  EMPLOYEE HANDBOOK.  By signing this Agreement, Executive acknowledges that
he has received and read the Company's employee handbook.  Executive agrees to
abide by all company policies and procedures.  Notwithstanding the foregoing, if
there shall be any conflict between this Agreement and such employee handbook,
the terms of this Agreement shall govern.

4.  INCENTIVE BONUS.

    4.1  CHANGE OF CONTROL.  For purposes of this Agreement, a Change of Control
    shall mean:

         (a)  any reorganization, consolidation or merger of the Company in 
         which the Company is not the surviving corporation or pursuant to which
         shares of the Company's voting stock would be converted into cash,
         securities or other property, in either case other than a merger of the
         Company in which the holders of the Company's voting stock immediately
         prior to the merger have the same proportionate ownership of voting
         stock of the surviving corporation immediately after the merger;

         (b)  the sale, exchange or other transfer (in one transaction 
         or a series of related transactions) to a third party not affiliated as
         of the date of this Agreement with the Company of at least twenty
         percent (20%) of the voting stock of the Company within a one-year
         period; or

         (c)  the sale, lease, exchange or other transfer (in one transaction 
         or a series of related transactions) of all, or substantially all, of
         the assets of the Company.

    4.2  BONUS. In the event of an Acquisition or a Change in Control, other 
    than the Merger, during Executive's active employment hereunder, he shall be
    entitled to receive a cash bonus equal to three times his then annual base
    salary, payable immediately after the closing of the transaction or the
    series of transactions effecting the Change of Control.

                                       2.

5.  TERMINATION OF EMPLOYMENT.

    5.1  TERM.  The initial term of this Agreement is from the date hereof until
    January 31, 2004.

    5.2  COMPANY INITIATED TERMINATION.

         (a)  In the event the Company terminates Executive's employment 
         without cause, Executive shall receive as severance a one-time payment
         equal to one month of his then annual salary multiplied by the number
         of calendar years (a fraction of a year shall be paid on a prorated
         basis), but not to exceed a total of twelve months, of Executive's
         service with the Company, payable within fifteen (15) days of such
         termination. No other benefits or payments shall be provided, except as
         expressly provided herein.

         (b)  In the event Executive's employment is terminated at any time 
         with cause, all of Executive's compensation and benefits will cease
         immediately, and Executive shall not be entitled to any severance
         benefits and all other benefits provided hereunder shall cease as of
         such termination. For purposes of this Agreement, "cause" shall mean
         (i) conviction of any felony or any crime involving moral turpitude or
         dishonesty; (ii) participation in a fraud or act of dishonesty against
         the Company; (iii) willful breach of the Company's policies; (iv)
         intentional damage to the Company's property; or (v) breach of this
         Agreement, the Proprietary Information Agreement, or any other
         agreements with the Company including, but not limited to agreements
         regarding confidentiality or proprietary information. Physical or
         mental disability shall not constitute "cause". Failure to accomplish
         corporate financial and management goals shall not constitute "cause".

         (c)  For purposes of this Agreement, "good reason" for voluntary 
         termination shall mean: (i) reduction of Executive's rate of salary
         compensation as in effect immediately prior to the Change of Control;
         (ii) failure to provide a package of welfare benefit plans which, taken
         as a whole, provide substantially similar benefits to those in which
         Executive is entitled to participate immediately prior to the Change of
         Control (except that employee contributions may be raised to the extent
         of any cost increases imposed by third parties) or any action by the
         Company which would adversely affect Executive's participation or
         reduce Executive's benefits under any of such plans; (iii) change in
         Executive's responsibilities, authority, titles or offices resulting in
         diminution of position, excluding for this purpose an isolated,
         insubstantial and inadvertent action not taken in bad faith which is
         remedied by the Company promptly after notice thereof is given by
         Executive; (iv) request that Executive relocate to a worksite that is
         more than 35 miles from his prior worksite, unless Executive accepts
         such relocation opportunity; (v) material reduction in duties; (vi)
         failure or refusal of the successor company to assume the Company's
         obligations under this Agreement; or (vii) material breach by the
         Company or any successor company of any of the material provisions of
         this Agreement.

         (d)  In the event Executive suffers and continues to suffer a 
         disability that renders him unable to perform the essential functions
         of his position, for three months within any six-month period
         ("Disability"), the Company shall, for

                                       3.
<PAGE>
 
         twelve months commencing at the conclusion of such three-month period
         of disability, (i) continue to pay Executive his annual base salary and
         (ii) maintain life insurance in the manner and in the amount set forth
         in Section 2.3(b) (ii) hereof. If upon the conclusion of the twelve-
         month period, Executive remains unable to perform the essential
         functions of the job, or the Company has no suitable vacant position
         for him, Executive's employment shall be terminated.

         (e) In the event of Executive's termination of employment hereunder
         either by the Company without cause, or by Executive for good reason,
         but not for reasons of Disability or death, within one year following a
         Change of Control other than the Merger, he shall be entitled to
         receive a cash payment equal to three times his average total annual
         cash compensation, including base salary and bonus, of the prior three
         years. The average of the prior three years ("Average") shall be
         computed by dividing by three the sum of all cash compensation he
         received from the Company during the three years prior to the
         termination.

         (f)  In the event of Executive's termination of employment hereunder 
         either by the Company without cause, or by Executive for good reason,
         but not for reasons of Disability or death, within one year following a
         Change of Control other than the Merger, Executive shall continue to
         receive all employment benefits as defined in Sections 2.2 and 2.3
         above, or their equivalent where benefit plan participation by
         Executive is not available, for eighteen (18) months following the
         termination.

         (g)  In the event of Executive's termination of employment hereunder 
         either by the Company without cause, or by Executive for good reason,
         but not for reasons of Disability or death, within one year following a
         Change of Control other than the Merger, the vesting of all shares of
         Company stock covered by options granted to Executive to purchase such
         Company shares, shall be accelerated such that all unvested such shares
         shall become vested as of the termination date.

         (h)  The incentive bonus in Section 4.2, and the severance pay in 
         Section 5.2(a), and the Change of Control severance pay in Section
         5.2(e) are intended to be cumulative. Executive may become entitled to
         receive more than one such benefit based on the same or related events.

         (i)  Except as expressly provided herein, Executive will not be 
         entitled to any other compensation, severance, pay-in-lieu of notice or
         any such compensation.

    5.3  EXECUTIVE INITIATED TERMINATION.  Executive may voluntarily terminate 
    his employment with the Company at any time by giving the Board 30 days
    written notice. In the event Executive voluntarily terminates his employment
    with the Company, all of Executive's compensation and benefits will cease as
    of such termination date. Executive acknowledges that he will not receive
    any severance pay or benefits, except as defined in the Employee Handbook,
    and except as specified in this Agreement at Section 5.2(e) if applicable,
    upon such voluntary termination.

                                       4.

6.  NOTICES.  All notices, requests, consents and other communications required
or permitted to be given hereunder shall be in writing and shall be deemed to
have been duly given if personally delivered or delivered by registered or
certified mail (return receipt requested), or private overnight mail (delivery
confirmed by such service, to the address listed below, or to such other address
as either party shall designate by notice in writing to the other in accordance
herein):

               IXYS Corporation
               3540 Bassett Street
               Santa Clara, CA  95054

               989 Covington Road
               Los Altos, California  94024

7.  ARBITRATION.  To ensure rapid and economical resolution of any and all
disputes which may arise under this Agreement, the Company and Executive each
agree that any and all disputes or controversies, whether of law or fact of any
nature whatsoever (including, but not limited to, all state and federal
statutory and discrimination claims), arising from or regarding the
interpretation, performance, enforcement or breach of this Agreement shall be
resolved by final and binding arbitration under the procedures set forth in
Exhibit A to this Agreement and the then existing Judicial Arbitration and
Mediation Services Rules of Practice and Procedure (except insofar as they are
inconsistent with the procedures set forth in Exhibit A).

8.  CERTAIN REDUCTIONS IN PAYMENTS OR BENEFITS. EXECUTIVE AND THE COMPANY HEREBY
AGREE AS FOLLOWS:

    8.1  Anything in this Agreement to the contrary notwithstanding, in the 
    event that any payment, distribution or other benefit provided by the
    Company to or for the benefit of Executive (whether paid or payable or
    provided or to be provided pursuant to the terms of this Agreement or
    otherwise) ("Payments") would (i) constitute a "parachute payment" within
    the meaning of Section 280G of the Internal Revenue Code (the "Code"), and
    (ii) but for this Section 8, be subject to the excise tax imposed by Section
    4999 of the Code (the "Excise Tax"), then, in accordance with this Section
    8, such Payments shall be reduced to the maximum amount that would result in
    no portion of the payments being subject to the Excise Tax, but only if and
    to the extent that such a reduction would result in Executive's receipt of
    Payments that are greater than the net amount Executive would receive (after
    application of the Excise Tax) if no reduction is made. The amount of
    required reduction, if any, shall be the smallest amount so that Executive's
    net proceeds with respect to the Payments (after taking into account payment
    of any Excise Tax and all federal, state and local income, employment or
    other taxes) shall be maximized. If, notwithstanding any reduction described
    in this Section 8 (or in the absence of any such reduction), the IRS
    determines that a Payment is subject to the Excise Tax (or subject to a
    different amount of the Excise Tax than determined by the Company or
    Executive), then Section 8.3 shall apply. If the Excise Tax is not
    eliminated pursuant to this Section 8, Executive shall pay the Excise Tax.

    8.2  All determinations required to be made under this Section 8 shall be 
    made by the Company's independent auditors. Such auditors shall provide
    detailed supporting

                                       5.
<PAGE>
 
    calculations both to the Company and Executive. Any such determination by
    the Company's independent auditors shall be binding upon the Company and
    Executive. Executive shall determine which and how much of the Payments,
    including without limitation any option acceleration benefits provided under
    this Agreement or otherwise ("Option Benefits"), shall be eliminated or
    reduced consistent with the requirements of this Section 8, provided that,
    if Executive does not make such determination within ten business days of
    the receipt of the calculations made by the Company's independent auditors,
    the Company shall elect which and how much of the Option Benefits or other
    Payments, as the case may be, shall be eliminated or reduced consistent with
    the requirements of this Section 8 and shall notify Executive promptly of
    such election. Within five business days thereafter, the Company shall pay
    to or distribute to or for the benefit of Executive such amounts as are then
    due to Executive under this Agreement.

    8.3  As a result of the uncertainty in the application of Section 280G of 
    the Code at the time of the initial determination by the Company's
    independent auditors hereunder, it is possible that Option Benefits or other
    Payments, as the case may be, will have been made by the Company which
    should not have been made ("Overpayment") or that additional Option Benefits
    or other Payments, as the case may be, which will not have been made by the
    Company could have been made ("Underpayment"), in each case, consistent with
    the calculations required to be made hereunder. In the event that the
    Company's independent auditors, based upon the assertion of a deficiency by
    the IRS against Executive or the Company which the Company's independent
    auditors believe has a high probability of success, determine that an
    Overpayment has been made, any such Overpayment paid or distributed by the
    Company to or for the benefit of Executive shall be treated for all purposes
    as a loan ab initio to Executive which Executive shall repay to the Company
    together with interest at the applicable federal rate provided for in
    Section 7872(f)(2) of the Code; provided, however, that no such loan shall
    be deemed to have been made and no amount shall be payable by Executive to
    the Company if and to the extent such deemed loan and payment would not
    either reduce the amount on which Executive is subject to tax under Section
    1 and Section 4999 of the Code or generate a refund of such taxes. In the
    event that the Company's independent auditors, based upon controlling
    precedent or other substantial authority, determine that an Underpayment has
    occurred, any such Underpayment shall be promptly paid by the Company to or
    for the benefit of Executive together with interest at the applicable
    federal rate provided for in Section 7872(f)(2) of the Code.

9.  CERTAIN DEFERRAL OF PAYMENTS. Notwithstanding the other provisions of this
Agreement, to the extent that any amounts payable to Executive pursuant to this
Agreement would not be deductible by the Company for federal income tax purposes
on account of the limitations of Section 162(m) of the Code, the Company may
defer payment of such amounts to the earliest one or more subsequent calendar
years in which the payment of such amounts would be deductible by the Company.

10.  GENERAL.

     10.1  ENTIRE AGREEMENT.  This Agreement sets forth the complete, final and
     exclusive embodiment of the entire agreement between Executive and the
     Company with respect to the subject matter hereof. This Agreement is
     entered into without reliance upon any promise, warranty or representation,
     written or oral, other than those expressly contained herein, and it
     supersedes any other such promises, warranties, representations or
     agreements.

                                       6.

     10.2  SEVERABILITY.  If any provision of this Agreement shall be held by 
     a court of competent jurisdiction to be excessively broad as to duration,
     activity or subject, it shall be deemed to extend only over the maximum
     duration, activity and/or subject as to which such provision shall be
     valid and enforceable under applicable law. If any provisions shall, for
     any reason, be held by a court of competent jurisdiction to be invalid,
     illegal or unenforceable, such invalidity, illegality or unenforceability
     shall not affect any other provision of this agreement, but this agreement
     shall be construed as if such invalid, illegal or unenforceable provision
     had never been contained herein.

     10.3  SUCCESSORS AND ASSIGNS.  This Agreement shall bind the heirs, 
     personal representatives, assigns, executors and administrators of each
     party, and inure to the benefit of each party, its heirs, successors and
     assigns. However, because of the unique and personal nature of Executive's
     duties under this Agreement, Executive agrees not to delegate the
     performance of his duties under this Agreement without the prior consent
     of the Board.

     10.4  APPLICABLE LAW.  This Agreement shall be deemed to have been 
     entered into and shall be construed in accordance with the laws of the
     state of California as applied to contracts made and to be performed
     entirely within California.

     10.5  HEADINGS.  The section headings contained herein are for reference
     purposes only and shall not in any way affect the meaning or interpretation
     of this Agreement.

     10.6  COUNTERPARTS.  This Agreement may be executed in two counterparts, 
     each of which shall be deemed an original, all of which together shall
     constitute one and the same instrument.

IN WITNESS WHEREOF, the parties have duly authorized and caused this Executive
Employment Agreement to be executed as follows:

Agreement or the termination of this Agreement shall be resolved by binding
arbitration in the manner described below.

2.   A party intending to seek resolution of any dispute under the Agreement by

which demand shall contain a brief statement of the issues to be resolved.

3.   The arbitration shall be conducted by a mutually acceptable retired judge
from the panel of Judicial Arbitration and Mediation Services, Inc. ("JAMS"). At
the request of either party, arbitration proceedings will be conducted in the
utmost secrecy and, in such case, all documents, testimony and records shall be
received, heard and maintained by the arbitrator in secrecy under seal,
available for inspection only by the parties t the arbitration, their respective
attorneys, and their respective expert consultants or witnesses who shall agree,

maintain such information in secrecy, and make no use of such information except
for the purposes of arbitration, unless compelled by legal process.

4.   The arbitrator is required to disclose any circumstances that might
preclude the arbitrator from rendering an objective and impartial determination.
In the event the parties cannot mutually agree upon the selection of a JAMS
ARBITRATOR, THE President and vice president of JAMS shall designate the
arbitrator.

5.   The party demanding arbitration shall promptly request that JAMS conduct a
scheduling conference within 15 days of the date of the that party's written
demand for arbitration or on the first available date thereafter on the
arbitrator's calendar. The arbitration hearing shall be held within 30 available

resolution of the arbitration.

6.   Discovery shall be conducted as follows: (a) prior to the arbitration any
party may make a written demands for lists of the witnesses to be called and the
documents to be introduced at the hearing; (b) the lists must be served within
15 days of the date of receipt of the demand, or one day prior to the
arbitration, whichever is earlier; and (c) each party may take no more than two
dispositions (pursuant to the procedure set forth in the California Code of
Civil Procedure) with a maximum of five hours of examination time per
deposition, and no other form of pre-arbitration discovery shall be permitted.

7.   It is the intent of the parties that the Federal Arbitration Act ("FAA")
shall apply to the enforcement of this provision unless it is held inapplicable
by a court with jurisdiction over the dispute, in which event the California
Arbitration Act ("CAA") shall apply.

8.   The arbitrator shall apply  California law, including the California
Evidence Code, and shall be able to decree any and all relief of an equitable
nature, including but not limited to such relief as a temporary restraining
order, a preliminary injunction, a permanent injunction, or replevin of Company
property.  The arbitrator shall also be able to award actual, general or
consequential damages, but shall not award any other form of damage (e.g.,
punitive damages).

9.   Each party shall pay its pro rata share of the arbitrator's fees and
expenses, in addition to other expenses of the arbitration approved by the
arbitrator, pending the resolution of the arbitration.  The arbitrator shall
have authority to award the payment of such fees and expenses to the prevailing
party, as appropriate in the discretion of the arbitrator.  Each party shall pay
its own attorneys' fees, witness fees and other expenses incurred for its own
benefit.

10.  The arbitrator shall render a written award setting forth the reasons for
his or her decision.  The decree or judgment of an award by the arbitrator may
be entered and enforced in any court having jurisdiction over the parties.  The
award of the arbitrator shall be final and binding upon the parties without
appeal or review except as permitted by the FAA, or if the FAA is not
applicable, as permitted by the CAA.

                              W I T N E S S E T H

         shares of the Company's voting stock would be converted into cash,
         securities or other property, in either case other than a merger of the

         stock of the surviving corporation immediately after the merger; or

         (b)  the sale, exchange or other transfer (in one transaction or a
         series of related transactions) to a third party not affiliated as of

         (20%) of the voting stock of the Company within a one-year period; or

5.  TERMINATION OF EMPLOYMENT.

    5.1  TERM.  The initial term of this Agreement is from the date hereof until
    January 31, 2004.

    5.2  COMPANY INITIATED TERMINATION.

         (a)  In the event the Company terminates Executive's employment without
         cause, Executive shall receive as severance a one-time payment equal to
         one month of his then annual salary multiplied by the number of
         calendar years (a fraction of a year shall be paid on a prorated
         basis), but not to exceed a total of twelve months, of Executive's
         service with the Company, payable within fifteen (15) days of such
         termination. No other benefits or payments shall be provided, except as
         expressly provided herein.

         (b)  In the event Executive's employment is terminated at any time with
         cause, all of Executive's compensation and benefits will cease
         immediately, and Executive shall not be entitled to any severance
         benefits and all other benefits provided hereunder shall cease as of
         such termination. For purposes of this Agreement, "cause" shall mean
         (i) conviction of any felony or any crime involving moral turpitude or
         dishonesty; (ii) participation in a fraud or act of dishonesty against
         the Company; (iii) willful breach of the Company's policies; (iv)
         intentional damage to the Company's property; or (v) breach of this
         Agreement, the Proprietary Information Agreement, or any other
         agreements with the Company including, but not limited to agreements
         regarding confidentiality or proprietary information. Physical or
         mental disability shall not constitute "cause". Failure to accomplish
         corporate financial and management goals shall not constitute "cause".

         (c)  For purposes of this Agreement, "good reason" for voluntary
         termination shall mean: (i) reduction of Executive's rate of salary
         compensation as in effect immediately prior to the Change of Control;
         (ii) failure to provide a package of welfare benefit plans which, taken
         as a whole, provide substantially similar benefits to those in which
         Executive is entitled to participate immediately prior to the Change of
         Control (except that employee contributions may be raised to the extent
         of any cost increases imposed by third parties) or any action by the
         Company which would adversely affect Executive's participation or
         reduce Executive's benefits under any of such plans; (iii) change in
         Executive's responsibilities, authority, titles or offices resulting in
         diminution of position, excluding for this purpose an isolated,
         insubstantial and inadvertent action not taken in bad faith which is
         remedied by the Company promptly after notice thereof is given by
         Executive; (iv) request that Executive relocate to a worksite that is
         more than 35 miles from his prior worksite, unless Executive accepts
         such relocation opportunity; (v) material reduction in duties; (vi)
         failure or refusal of the successor company to assume the Company's
         obligations under this Agreement; or (vii) material breach by the
         Company or any successor company of any of the material provisions of
         this Agreement.

         (d)  In the event Executive suffers and continues to suffer a
         disability that renders him unable to perform the essential functions
         of his position, for three months within any six-month period
         ("Disability"), the Company shall, for 

                                       3.
<PAGE>
 
         twelve months commencing at the conclusion of such three-month period
         of disability, (i) continue to pay Executive his annual base salary and
         (ii) maintain life insurance in the manner and in the amount set forth
         in Section 2.3(b) (ii) hereof. If upon the conclusion of the twelve-
         month period, Executive remains unable to perform the essential
         functions of the job, or the Company has no suitable vacant position
         for him, Executive's employment shall be terminated.

         (e)  In the event of Executive's termination of employment hereunder
         either by the Company without cause, or by Executive for good reason,
         but not for reasons of Disability or death, within one year following a
         Change of Control other than the Merger, he shall be entitled to
         receive a cash payment equal to three times his average total annual
         cash compensation, including base salary and bonus, of the prior three
         years. The average of the prior three years ("Average") shall be
         computed by dividing by three the sum of all cash compensation he
         received from the Company during the three years prior to the
         termination.

         (f)  In the event of Executive's termination of employment hereunder
         either by the Company without cause, or by Executive for good reason,
         but not for reasons of Disability or death, within one year following a
         Change of Control other than the Merger, Executive shall continue to
         receive all employment benefits as defined in Sections 2.2 and 2.3
         above, or their equivalent where benefit plan participation by
         Executive is not available, for eighteen (18) months following the
         termination.

         (g)  In the event of Executive's termination of employment hereunder
         either by the Company without cause, or by Executive for good reason,
         but not for reasons of Disability or death, within one year following a
         Change of Control other than the Merger, the vesting of all shares of
         Company stock covered by options granted to Executive to purchase such
         Company shares, shall be accelerated such that all unvested such shares
         shall become vested as of the termination date.

         (h)  The incentive bonus in Section 4.2, and the severance pay in
         Section 5.2(a), and the Change of Control severance pay in Section
         5.2(e) are intended to be cumulative. Executive may become entitled to
         receive more than one such benefit based on the same or related events.

         (i)  Except as expressly provided herein, Executive will not be
         entitled to any other compensation, severance, pay-in-lieu of notice or
         any such compensation.

    5.3  EXECUTIVE INITIATED TERMINATION.  Executive may voluntarily terminate
    his employment with the Company at any time by giving the Board 30 days
    written notice. In the event Executive voluntarily terminates his employment
    with the Company, all of Executive's compensation and benefits will cease as
    of such termination date. Executive acknowledges that he will not receive
    any severance pay or benefits, except as defined in the Employee Handbook,
    and except as specified in this Agreement at Section 5.2(e) if applicable,
    upon such voluntary termination.

6.  NOTICES.  All notices, requests, consents and other communications required
or permitted to be given hereunder shall be in writing and shall be deemed to

confirmed by such service, to the address listed below, or to such other address
as either party shall designate by notice in writing to the other in accordance
herein):

               Gilroy, CA  95020

7.  ARBITRATION.  To ensure rapid and economical resolution of any and all
disputes which may arise under this Agreement, the Company and Executive each
agree that any and all disputes or controversies, whether of law or fact of any
nature whatsoever (including, but not limited to, all state and federal
statutory and discrimination claims), arising from or regarding the
interpretation, performance, enforcement or breach of this Agreement shall be
resolved by final and binding arbitration under the procedures set forth in
Exhibit A to this Agreement and the then existing Judicial Arbitration and
Mediation Services Rules of Practice and Procedure (except insofar as they are
inconsistent with the procedures set forth in Exhibit A).

8.  CERTAIN REDUCTIONS IN PAYMENTS OR BENEFITS. Executive and the Company hereby
agree as follows:

    8.1  Anything in this Agreement to the contrary notwithstanding, in the
    event that any payment, distribution or other benefit provided by the
    Company to or for the benefit of Executive (whether paid or payable or
    provided or to be provided pursuant to the terms of this Agreement or
    otherwise) ("Payments") would (i) constitute a "parachute payment" within
    the meaning of Section 280G of the Internal Revenue Code (the "Code"), and
    (ii) but for this Section 8, be subject to the excise tax imposed by Section
    4999 of the Code (the "Excise Tax"), then, in accordance with this Section
    8, such Payments shall be reduced to the maximum amount that would result in
    no portion of the payments being subject to the Excise Tax, but only if and
    to the extent that such a reduction would result in Executive's receipt of
    Payments that are greater than the net amount Executive would receive (after
    application of the Excise Tax) if no reduction is made. The amount of
    required reduction, if any, shall be the smallest amount so that Executive's
    net proceeds with respect to the Payments (after taking into account payment
    of any Excise Tax and all federal, state and local income, employment or
    other taxes) shall be maximized. If, notwithstanding any reduction described
    in this Section 8 (or in the absence of any such reduction), the IRS
    determines that a Payment is subject to the Excise Tax (or subject to a
    different amount of the Excise Tax than determined by the Company or
    Executive), then Section ) 8.3 shall apply. If the Excise Tax is not
    eliminated pursuant to this Section 8, Executive shall pay the Excise Tax.

    8.2  All determinations required to be made under this Section 8 shall be
    made by the Company's independent auditors. Such auditors shall provide
    detailed supporting 

                                       5.

    calculations both to the Company and Executive. Any such determination by
    the Company's independent auditors shall be binding upon the Company and
    Executive. Executive shall determine which and how much of the Payments,
    including without limitation any option acceleration benefits provided under
    this Agreement or otherwise ("Option Benefits"), shall be eliminated or
    reduced consistent with the requirements of this Section 8, provided that,
    if Executive does not make such determination within ten business days of
    the receipt of the calculations made by the Company's independent auditors,
    the Company shall elect which and how much of the Option Benefits or other
    Payments, as the case may be, shall be eliminated or reduced consistent with
    the requirements of this Section 8 and shall notify Executive promptly of
    such election. Within five business days thereafter, the Company shall pay
    to or distribute to or for the benefit of Executive such amounts as are then
    due to Executive under this Agreement.

    8.3  As a result of the uncertainty in the application of Section 280G of
    the Code at the time of the initial determination by the Company's
    independent auditors hereunder, it is possible that Option Benefits or other
    Payments, as the case may be, will have been made by the Company which
    should not have been made ("Overpayment") or that additional Option Benefits
    or other Payments, as the case may be, which will not have been made by the
    Company could have been made ("Underpayment"), in each case, consistent with
    the calculations required to be made hereunder. In the event that the
    Company's independent auditors, based upon the assertion of a deficiency by
    the IRS against Executive or the Company which the Company's independent
    auditors believe has a high probability of success, determine that an
    Overpayment has been made, any such Overpayment paid or distributed by the
    Company to or for the benefit of Executive shall be treated for all purposes
    as a loan ab initio to Executive which Executive shall repay to the Company
    together with interest at the applicable federal rate provided for in
    Section 7872(f)(2) of the Code; provided, however, that no such loan shall
    be deemed to have been made and no amount shall be payable by Executive to
    the Company if and to the extent such deemed loan and payment would not
    either reduce the amount on which Executive is subject to tax under Section
    1 and Section 4999 of the Code or generate a refund of such taxes. In the
    event that the Company's independent auditors, based upon controlling
    precedent or other substantial authority, determine that an Underpayment has
    occurred, any such Underpayment shall be promptly paid by the Company to or
    for the benefit of Executive together with interest at the applicable
    federal rate provided for in Section 7872(f)(2) of the Code.

9.  CERTAIN DEFERRAL OF PAYMENTS. Notwithstanding the other provisions of this
    Agreement, to the extent that any amounts payable to Executive pursuant to
    this Agreement would not be deductible by the Company for federal income tax
    purposes on account of the limitations of Section 162(m) of the Code, the
    Company may defer payment of such amounts to the earliest one or more
    subsequent calendar years in which the payment of such amounts would be
    deductible by the Company.

10.  GENERAL.

     10.1  ENTIRE AGREEMENT.  This Agreement sets forth the complete, final and
     exclusive embodiment of the entire agreement between Executive and the
     Company with respect to the subject matter hereof. This Agreement is
     entered into without reliance upon any promise, warranty or representation,
     written or oral, other than those expressly contained herein, and it
     supersedes any other such promises, warranties, representations or
     agreements.

                                       6.

     10.2  SEVERABILITY.  If any provision of this Agreement shall be held by a
     court of competent jurisdiction to be excessively broad as to duration,
     activity or subject, it shall be deemed to extend only over the maximum
     duration, activity and/or subject as to which such provision shall be valid
     and enforceable under applicable law. If any provisions shall, for any
     reason, be held by a court of competent jurisdiction to be invalid, illegal
     or unenforceable, such invalidity, illegality or unenforceability shall not
     affect any other provision of this agreement, but this agreement shall be
     construed as if such invalid, illegal or unenforceable provision had never
     been contained herein.

     10.3  SUCCESSORS AND ASSIGNS.  This Agreement shall bind the heirs,
     personal representatives, assigns, executors and administrators of each
     party, and inure to the benefit of each party, its heirs, successors and
     assigns. However, because of the unique and personal nature of Executive's
     duties under this Agreement, Executive agrees not to delegate the
     performance of his duties under this Agreement without the prior consent of
     the Board.

     10.4  APPLICABLE LAW.  This Agreement shall be deemed to have been entered
     into and shall be construed in accordance with the laws of the state of
     California as applied to contracts made and to be performed entirely within
     California.

     10.5  HEADINGS.  The section headings contained herein are for reference
     purposes only and shall not in any way affect the meaning or interpretation
     of this Agreement.

     10.6  COUNTERPARTS.  This Agreement may be executed in two counterparts,
     each of which shall be deemed an original, all of which together shall
     constitute one and the same instrument.

IN WITNESS WHEREOF, the parties have duly authorized and caused this Executive
Employment Agreement to be executed as follows:

                             ARBITRATION PROCEDURE


1.   The parties agree that any dispute that arises in connection with this
Agreement or the termination of this Agreement shall be resolved by binding
arbitration in the manner described below.

2.   A party intending to seek resolution of any dispute under the Agreement by
arbitration shall provide a written demand for arbitration to the other party,
which demand shall contain a brief statement of the issues to be resolved.

3.   The arbitration shall be conducted by a mutually acceptable retired judge
from the panel of Judicial Arbitration and Mediation Services, Inc. ("JAMS"). At
the request of either party, arbitration proceedings will be conducted in the
utmost secrecy and, in such case, all documents, testimony and records shall be
received, heard and maintained by the arbitrator in secrecy under seal,
available for inspection only by the parties t the arbitration, their respective
attorneys, and their respective expert consultants or witnesses who shall agree,
in advance and in writing, to receive all such information confidentially and to
maintain such information in secrecy, and make no use of such information except
for the purposes of arbitration, unless compelled by legal process.

4.   The arbitrator is required to disclose any circumstances that might
preclude the arbitrator from rendering an objective and impartial determination.
In the event the parties cannot mutually agree upon the selection of a JAMS
ARBITRATOR, THE President and vice president of JAMS shall designate the
arbitrator.

5.   The party demanding arbitration shall promptly request that JAMS conduct a
scheduling conference within 15 days of the date of the that party's written
demand for arbitration or on the first available date thereafter on the
arbitrator's calendar. The arbitration hearing shall be held within 30 available
date thereafter on the arbitrator's calendar. Nothing in this paragraph shall
prevent a party from seeking temporary equitable relief at any time, from JAMS
or any court of competent jurisdiction, to prevent irreparable harm pending the
resolution of the arbitration.

6.   Discovery shall be conducted as follows: (a) prior to the arbitration any
party may make a written demands for lists of the witnesses to be called and the
documents to be introduced at the hearing; (b) the lists must be served within
15 days of the date of receipt of the demand, or one day prior to the
arbitration, whichever is earlier; and (c) each party may take no more than two
dispositions (pursuant to the procedure set forth in the California Code of
Civil Procedure) with a maximum of five hours of examination time per
deposition, and no other form of pre-arbitration discovery shall be permitted.

7.   It is the intent of the parties that the Federal Arbitration Act ("FAA")
shall apply to the enforcement of this provision unless it is held inapplicable
by a court with jurisdiction over the dispute, in which event the California
Arbitration Act ("CAA") shall apply.

8.   The arbitrator shall apply California law, including the California
Evidence Code, and shall be able to decree any and all relief of an equitable
nature, including but not limited to such relief as a temporary restraining
order, a preliminary injunction, a permanent injunction, or replevin of Company
property.  The arbitrator shall also be able to award actual, general or
consequential damages, but shall not award any other form of damage (e.g.,
punitive damages).

                                       8.

9.   Each party shall pay its pro rata share of the arbitrator's fees and
expenses, in addition to other expenses of the arbitration approved by the
arbitrator, pending the resolution of the arbitration.  The arbitrator shall
have authority to award the payment of such fees and expenses to the prevailing
party, as appropriate in the discretion of the arbitrator.  Each party shall pay
its own attorneys' fees, witness fees and other expenses incurred for its own
benefit.

10.  The arbitrator shall render a written award setting forth the reasons for
his or her decision.  The decree or judgment of an award by the arbitrator may
be entered and enforced in any court having jurisdiction over the parties.  The
award of the arbitrator shall be final and binding upon the parties without
appeal or review except as permitted by the FAA, or if the FAA is not
applicable, as permitted by the CAA.
