                               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 __, 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

                                       1.



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;

        (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:

                                   A = 19 x B
                                       ------
                                          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:

                                D = $150,000,000
                                    ------------
                                       (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 including) the trading day two
business days prior to the date of the Parent Stockholders' Meeting,
appropriately adjusted to reflect the completion of 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 

                                       3.



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 Warrant in
accordance with the terms (as in effect as of 

                                       4.



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 

                                       5.



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 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.

                                       6.



        1.8  Appraisal Rights. Notwithstanding anything to the contrary
contained in this Agreement, any shares of Company Capital Stock for which, as
of the Effective Time, "appraisal rights" within the meaning of Section 262 of
the DGCL shall have been perfected, shall not be converted into or represent the
right to receive Parent Common Stock in accordance with Section 1.5 (or cash in
lieu of fractional shares in accordance with Section 1.5(d)), and the holder or
holders of such shares shall be entitled only to such rights as may be granted
to such holder or holders in Section 262 of the DGCL; PROVIDED, HOWEVER, if any
holders of such shares shall lose its appraisal rights, then, as of the later of
the Effective Time or the loss of such rights, such shares shall automatically
be converted into and shall represent only the right to receive (upon the
surrender of the certificate or certificates representing such shares) Parent
Common Stock in accordance with Section 1.5 (and cash in lieu of fractional
shares in accordance with Section 1.5(d)).

        1.9  Tax Consequences. For federal income tax purposes, the Merger
is intended to constitute a reorganization within the meaning of Section 368 of
the Code. The parties to this Agreement hereby adopt this Agreement as a "plan
of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of
the United States Treasury Regulations.

        1.10  Accounting Consequences. For financial reporting purposes,
the Merger is intended to be accounted for as a "purchase."

        1.11  Further Action. If, at any time after the Effective Time,
any further action is determined by Parent to be necessary or desirable to carry
out the purposes of this Agreement or to vest the Surviving Corporation with
full right, title and possession of and to all rights and property of Merger Sub
and the Company, the officers and directors of the Surviving Corporation and
Parent shall be fully authorized (in the name of Merger Sub, in the name of the
Company and otherwise) to take such action.

        2.6  Title to Assets.

        (a)  Part 2.6 of the Acquired Corporation Disclosure Schedule contains a
complete and accurate list of all real property, leaseholds, or other interests
in real property owned by the Acquired Corporations (all such property owned by

Encumbrances, except for (1) any lien for current taxes not yet due and payable,

        2.7  Receivables; Inventory.

        (a) All existing accounts receivable of the Acquired Corporations

not yet been collected and those accounts receivable that have arisen since

transactions entered into in the ordinary course of business and (ii), to the
best of the Company's knowledge, except as set forth in Part 2.7(a) of the
Acquired Corporation Disclosure Schedule, will be collected in full, without any

quantity usable and salable in the ordinary course of business, except for
obsolete items and items of below-standard quality, all of which have been

Interim Balance Sheet. All inventories not written off have been priced at the
lower of cost or net realizable value on a first in, first out basis. The
quantities of each item of inventory (whether raw materials, work-in-process or
finished goods) are not excessive, but are reasonable in the present
circumstances of the Acquired Corporations.

        2.8  Buildings, Equipment; Leasehold. The buildings, plants,

Disclosure Schedule identifies and provides a brief description of any ongoing
royalty or payment obligations in excess of $10,000 with respect to, each
Proprietary Asset that is licensed or otherwise made available to any of the

licensed to any of the Acquired Corporations under any third party software
license generally available to the public at a price per central processing unit
less than $5,000), and identifies the Contract under which such Proprietary
Asset is being licensed or otherwise made available to such Acquired
Corporation. To the Company's knowledge, the Acquired Corporations have good,

of all Encumbrances, except for (i) any lien for current taxes not yet due and
payable and (ii) minor 

                                      12.

assets subject thereto or materially impair the operations of any of the
Acquired Corporations. The Acquired Corporations have a valid right to use,
license and otherwise exploit all Proprietary Assets identified in Part
2.9(a)(ii) of the Acquired Corporation Disclosure Schedule. Except as set forth
in Part 2.9(a)(iii) of the Acquired Corporation Disclosure Schedule, none of the

Proprietary Asset.

        (b) Each of the Acquired Corporations has taken reasonable measures and
precautions to protect and maintain the confidentiality, secrecy and value of
all material Acquired Corporation Proprietary Assets (except Acquired
Corporation Proprietary Assets whose value would be unimpaired by disclosure).
Without limiting the generality of the foregoing, except as set forth in Part
2.9(b) of the Acquired Corporation Disclosure Schedule, (i) all current
employees of the Acquired Corporations who are or were involved in, or who have
contributed to, the creation or development of any material Acquired Corporation
Proprietary Asset have executed and delivered to the Company an agreement that
is substantially identical to the form of Confidential Information and Invention
Assignment Agreement previously delivered by the Company to Parent and (ii) all
current consultants and independent contractors to the Acquired Corporations who
are or were involved in, or who have contributed to, the creation or development
of any Acquired Corporation Proprietary Asset have executed and delivered to the
Company 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 the Company to Parent. No current or former employee, officer, director,
stockholder, consultant or independent contractor has any right, claim or
interest in or with respect to any Acquired Corporation Proprietary Asset. None
of the Acquired Corporations has 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

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

business has been and is being conducted. Parent has not (i) licensed any of the
material Parent Proprietary Assets to any Person on an exclusive basis, or (ii)

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.

                                      36.



        (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.

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

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 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

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.

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,

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)

operations of Parent.

                                      38.

interfering with, the Merger or any of the other transactions contemplated by

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

contemplated by this Agreement, and to submit promptly any additional
information requested by any such Governmental Body. Without limiting the
generality of the foregoing, Parent shall, and the Company shall use reasonable
efforts to cause Asea Brown Boveri AG ("ABB") to, prepare and file the
notifications required under the HSR Act in connection with the Merger. The
Company and Parent shall respond as promptly as practicable to (a) any inquiries
or requests received from the Federal Trade Commission or the Department of
Justice for additional information or documentation and (b) any inquiries or
requests received from any state attorney general or other Governmental Body in
connection with antitrust or related matters. The Company and Parent shall (1)
give each other prompt notice of the commencement of any Legal Proceeding by or
before any Governmental Body with respect to the Merger or any of the other
transactions contemplated by this Agreement, (2) keep the other party informed
as to the status of any such Legal Proceeding, and (3) promptly inform the other
party of any communication to or from the Federal Trade Commission, the
Department of Justice or any other Governmental Body regarding the Merger. To
the extent within their control, the Company and Parent will consult and
cooperate with one another, and will consider in good faith the views of one
another, in connection with any analysis, appearance, presentation, memorandum,
brief, argument, opinion or proposal made or submitted in connection with any
Legal Proceeding under or relating to the HSR Act or any other federal or state
antitrust or fair trade law. In addition, except as may be prohibited by any
Governmental Body or by any Legal Requirement, to the extent permitted by ABB,
in connection with any Legal Proceeding under or relating to the HSR Act or any
other federal or state antitrust or fair trade law or any other similar Legal
Proceeding, each of the Company and Parent agrees to permit authorized
Representatives of the other party to be present at each meeting or conference
relating to any such Legal Proceeding and to have access to and be consulted in
connection with any document, opinion or proposal made or submitted to any
Governmental Body in connection with any such Legal Proceeding.

        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 

                                      51.



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.

                                      52.



        (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.

Agreement, (ii) shall use all reasonable efforts to obtain each Consent (if any)

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 (i) to dispose of any assets; (ii) to discontinue offering any
product; (iii) 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 

                                      53.

Section 6.9(a).

        (c) Parent and the Company shall use all reasonable efforts prior to the
Effective Time to cause the Merger to qualify as a tax free reorganization under
Section 368(a) of the Code.

        (d) Following delivery of the tax representation letters pursuant to
Section 6.9(a), each of Parent and the Company shall use its reasonable efforts
to cause Pillsbury Madison & Sutro LLP and Cooley Godward LLP, respectively, to
deliver promptly to it a legal opinion satisfying the requirements of Item 601
of Regulation S-K promulgated under the Securities Act. In rendering such
opinions, each of such counsel shall be entitled to rely on the tax
representation letters delivered pursuant to Section 6.9(a).

        6.10  Corporate Governance.

employee at the request of the Company, shall be considered for all purposes a
termination of such employee without cause. A resignation by an individual as a
director or officer of Parent shall not, in and of itself, constitute a
resignation as an employee as described in this Section 6.11.

                                      54.

                                       II.

        The address, including street, number, city, and county, of the
registered office of the corporation in the State of Delaware is 32 Loockerman
Square, Suite L-100, City of Dover, 19901, County of Kent; and the name of the

The Prentice-Hall Corporation System, Inc.

                                      III.

        The purpose of this corporation is to engage in any lawful act or
activity for which a corporation may be organized under the Delaware General
Corporation Law.

                                       IV.

        1. This corporation is authorized to issue one class of stock to be

one-tenth of one cent ($0.001).

                                       V.

        For the management of the business and for the conduct of the affairs of
the corporation, and in further definition, limitation and regulation of the
powers of the corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:

        1. The management of the business and the conduct of the affairs of the
corporation shall be vested in its Board of Directors. The number of directors
which shall constitute the whole Board of Directors shall be fixed by the Board
of Directors in the manner provided in the Bylaws.

        2. The Board of Directors may from time to time make, amend, supplement
or repeal the Bylaws; provided, however, that the stockholders may change or
repeal any Bylaw adopted by the Board of Directors by the affirmative vote of
the holders of a majority of the voting power of all of the then outstanding
shares of the capital stock of the corporation (considered for this purpose as
one class); and, provided further, that no amendment or supplement to the Bylaws
adopted by the Board of Directors shall vary or conflict with any amendment or
supplement thus adopted by the stockholders.

        3. The directors of the corporation need not be elected by written
ballot unless the Bylaws so provide.

Law as the same exists or as may hereafter be amended, no director of the
corporation shall be personally liable to the corporation or its stockholders
for monetary damages for breach 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 involved 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. If the Delaware
General Corporation law is amended after approval by the stockholders of this
Article to authorize corporate action further eliminating or limiting the
personal liability of directors, then the liability of a director shall be
eliminated or limited to the fullest extent permitted by the Delaware General
Corporation law, as so amended.

        2. Neither any amendment nor repeal of this Article VI, nor the adoption
of any provisions of the Corporation's Certificate of Incorporation inconsistent
with this Article VI, shall eliminate or reduce the effect on this Article VI,
in respect of any matter occurring, or any action, suite, claim or proceeding
accruing or arising or that, but for this Article VI, would accrue or arise,
prior to such amendment, repeal, or adoption of an inconsistent provision.

                               AFFILIATE AGREEMENT


        THIS AFFILIATE AGREEMENT is being executed and delivered as of
___________________, 1998 by ____________________ ("Stockholder") in favor of
and for the benefit of Paradigm Technology, Inc., a Delaware corporation
("Parent").

                                    RECITALS

        A. Stockholder is a Stockholder and is an officer and director of IXYS
Corporation, a Delaware corporation (the "Company").

        B. Parent, the Company, and Paradigm Enterprises, Inc., a Delaware
corporation and a wholly owned subsidiary of Parent ("Merger Sub"), have entered
into an Agreement and Plan of Merger and Reorganization dated as of March ___,
1998 (the "Merger Agreement"), providing for the merger of Merger Sub into the
Company (the "Merger"). The Merger Agreement contemplates that, upon
consummation of the Merger, (i) holders of shares of the capital stock of the
Company will receive shares of common stock of Parent ("Parent Common Stock") in
exchange for their shares of capital stock of the Company and (ii) the Company
will become a wholly owned subsidiary of Parent. It is accordingly contemplated
that Stockholder will receive shares of Parent Common Stock in the Merger.

        C. Stockholder understands that the Parent Common Stock being issued in
the Merger will be issued pursuant to a registration statement on Form S-4, and
that Stockholder may be deemed an "affiliate" of Parent as such term is defined
for purposes of paragraphs (c) and (d) of Rule 145 of the General Rules and
Regulations of the Securities and Exchange Commission ("Rule 145") under the
Securities Act of 1933, as amended (the "Act"), and, as such, Stockholder may
only transfer, sell or dispose of such Parent Common Stock in accordance with
this Affiliate Agreement and Rule 145.

                                    AGREEMENT

        1. REPRESENTATIONS AND WARRANTIES. Stockholder represents and warrants
to Parent as follows:

        a.  Stockholder is the holder and "beneficial owner" (as defined in
Rule 13d-3 under the Securities Exchange Act of 1934, as amended) of the number
and class of shares of capital stock of the Company set forth beneath
Stockholder's signature on the signature page hereof (the "Company Shares"), and
Stockholder has good and valid title to the Company Shares, free and clear of
any liens, pledges, security interests, adverse claims, equities, options,
proxies, charges, encumbrances or restrictions of any nature.

                                       1.



        b.  Stockholder has carefully read this Affiliate Agreement, and to
the extent Stockholder felt necessary, has discussed with counsel the
limitations imposed on Stockholder's ability to sell, transfer or otherwise
dispose of the shares of Parent Common Stock that Stockholder is to receive in
the Merger (the "Parent Shares"). Stockholder fully understands the limitations
this Affiliate Agreement places upon Stockholder's ability to sell, transfer or
otherwise dispose of the Parent Shares.

        c. Stockholder understands that the representations, warranties and
covenants set forth in this Affiliate Agreement will be relied upon by Parent
and its counsel for purposes of determining whether Parent should proceed with
the Merger and for various other purposes.

        2. PROHIBITIONS AGAINST TRANSFER. Stockholder agrees that Stockholder
shall not effect any sale, transfer or other disposition of any Parent Shares
unless:

        a.  such sale, transfer or other disposition is effected pursuant to
an effective registration statement under the Act;

        b. such sale, transfer or other disposition is made in conformity
with the requirements of Rule 145 under the Act, as evidenced by a broker's
letter and a representation letter executed by Stockholder (satisfactory in form
and content to Parent) stating that such requirements have been met;

        c.  counsel reasonably satisfactory to Parent shall have advised
Parent in a written opinion letter (satisfactory in form and content to Parent),
upon which Parent may rely, that such sale, transfer or other disposition will
be exempt from registration under the Act; or

        d.  an authorized representative of the SEC shall have rendered
written advice to Stockholder to the effect that the SEC would take no action,
or that the staff of the SEC would not recommend that the SEC take action, with
respect to such sale, transfer or other disposition, and a copy of such written
advice and all other related communications with the SEC shall have been
delivered to Parent.

        3. STOP TRANSFER INSTRUCTIONS; LEGEND.

        Stockholder acknowledges and agrees that (a) stop transfer instructions
will be given to Parent's transfer agent with respect to the Parent Shares, and
(b) each certificate representing any of such shares shall bear a legend
identical or similar in effect to the following legend (together with any other
legend or legends required by applicable state securities laws or otherwise):

               "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED

Stockholder set forth in this Affiliate Agreement shall be construed as
independent of any other agreement or arrangement between Stockholder, on the
one hand, and the Company or Parent, on the other. The existence of any claim or
cause of action by Stockholder against the Company or Parent shall not
constitute a defense to the enforcement of any of such covenants or obligations
against Stockholder.

        5.  SPECIFIC PERFORMANCE. Stockholder agrees that in the event of
any breach or threatened breach by Stockholder of any covenant, obligation or
other provision contained in this Affiliate Agreement, Parent shall be entitled

and performance of such covenant, obligation or other provision; and (b) an

for, any loss, damage, injury, decline in value, lost opportunity, liability,
exposure, claim, demand, settlement, judgment, award, fine, penalty, tax, fee,
charge, cost or expense of any nature (whether or not relating to a third party
claim) which is directly or indirectly suffered or incurred at any time by
Parent or any of Parent's affiliates or to which Parent or any of Parent's
affiliates otherwise becomes subject and that arises from any inaccuracy in or

RE:     MERGER PURSUANT TO THE AGREEMENT AND PLAN OF MERGER AND REORGANIZATION
        (THE "MERGER AGREEMENT") DATED __________, 1998, 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"), AND THE RELATED CERTIFICATE OF MERGER BETWEEN MERGER
        SUB AND THE COMPANY (THE "CERTIFICATE OF MERGER").

Gentlemen:

This letter is supplied to you in connection with your rendering of opinions
regarding certain federal income tax consequences of the Merger. Unless
otherwise indicated, capitalized terms not defined herein have the meanings set
forth in the Merger Agreement. The Merger Agreement and the Certificate of
Merger, including exhibits and schedules attached thereto, are collectively
referred to as the "AGREEMENTS."

After consulting with their counsel and auditors regarding the meaning of and
factual support for the following representations, the undersigned hereby
certify and represent that the following facts are now true and will continue to
be true as of the Effective Time of the Merger and thereafter where relevant:

        1. Pursuant to the Merger, Merger Sub will merge with and into the
Company, and the Company will acquire all of the assets and liabilities of
Merger Sub. Specifically, the assets transferred to the Company pursuant to the
Merger will represent at least ninety percent (90%) of the fair market value of
the net assets and at least seventy percent (70%) of the fair market value of
the gross assets held by Merger Sub immediately prior to the Merger. In
addition, at least ninety percent (90%) of the fair market value of the net
assets and at least seventy percent (70%) of the fair market value of the gross
assets held by the Company immediately prior to the Merger will continue to be
held by the Company immediately after the Merger. For the purpose of determining
the percentage of the Company's and Merger Sub's net and gross assets held by
the Company immediately following the Merger, the following assets will be
treated as property held by Merger Sub or the Company, as the case may be,
immediately prior but not subsequent to the Merger: (i) assets disposed of by
the Company or Merger Sub (other than assets transferred from Merger Sub to the
Company in the Merger) prior to or subsequent to the Merger and in contemplation
thereof (including without limitation any asset disposed of by the Company,
other than in the ordinary course of business, pursuant to a plan or intent
existing 



during the period ending at the Effective Time of the Merger and beginning with
the commencement of negotiations (whether formal or informal) with Parent
regarding the Merger (the "PRE-MERGER PERIOD"); (ii) assets used by the Company
or Merger Sub to pay stockholders perfecting appraisal rights or other expenses
or liabilities incurred in connection with the Merger and (iii) assets used to
make distribution, redemption or other payments in respect of stock of the
Company or rights to acquire such stock (including payments treated as such for
tax purposes) that are made in contemplation of the Merger or that are related
thereto;

        2. Parent's principal reasons for participating in the Merger are bona
fide business purposes not related to taxes;

        3. Prior to the Merger, Parent will be in "CONTROL" of Merger Sub. As
used in this letter, "CONTROL" shall consist of direct ownership of shares of
stock possessing at least eighty percent (80%) of the total combined voting
power of all classes of stock entitled to vote and at least eighty percent (80%)
of the total number of shares of all other classes of stock of the corporation.
For purposes of determining Control, a person shall not be considered to own
shares of voting stock if rights to vote such shares (or to restrict or
otherwise control the voting of such shares) are held by a third party
(including a voting trust) other than an agent of such person;

        4. In the Merger, shares of stock of the Company representing Control of
the Company will be exchanged solely for shares of Parent Common Stock. For
purposes of this paragraph, shares of stock of the Company exchanged in the
Merger for cash and other property (including, without limitation, cash paid to
stockholders of the Company perfecting appraisal rights, if any, or in lieu of
fractional shares of Parent Common Stock) will be treated as shares of stock of
the Company outstanding on the date of the Merger but not exchanged for shares
of Parent Common Stock;

        5. Parent has no plan or intention to cause the Company to issue
additional shares of stock after the Merger, or take any other action, that
would result in Parent losing Control of the Company;

        6. Parent has no plan or intention to reacquire any of its stock issued
pursuant to the Merger;

        7. Except for transfers described in both Section 368(a)(2)(C) of the
Code and Treasury Regulation Section 1.368-2(j)(4), Parent has no plan or
intention to: (a) liquidate the Company; (b) merge the Company with or into
another corporation including Parent or its affiliates; (c) sell, distribute or
otherwise dispose of the stock of the Company, to cause the Company to sell or
otherwise dispose of the stock of the Company; or (d) cause the Company to sell
or otherwise dispose of any of its assets or of any assets acquired from Merger
Sub, except for dispositions made in the ordinary course of business or payment
of expenses incurred by the Company pursuant to the Merger;

        8. In the Merger, Merger Sub will have no liabilities assumed by the
Company and will not transfer to the Company any assets subject to liabilities,
except to the extent incurred in connection with the transactions contemplated
by the Agreements;

                                       2.



        9. Parent intends that, following the Merger, the Company will continue
its historic business or use a significant portion of its historic business
assets in a business;

        10. During the past five (5) years, none of the outstanding shares of
capital stock of the Company, including the right to acquire or vote any such
shares have, directly or indirectly, been owned by Parent or affiliates of
Parent;

        11. Parent is not an investment Company within the meaning of Section
368(a)(F)(iii) and (iv) of the Code;

        12. No stockholder of the Company is acting as agent for Parent in
connection with the Merger or the approval thereof; Parent will not reimburse
any stockholder of the Company for any stock of the Company such stockholder may
have purchased or for other obligations such stockholder may have incurred; 

        13. Neither Parent nor Merger Sub is, or will be at the Effective Time
of the Merger, under the jurisdiction of a court in a Title 11 or similar case
within the meaning of Section 368(a)(3)(A) of the Code;

        14. Except for repurchases or redemptions of Parent Common Stock that
are consistent with past practices and pursuant to pre-existing purchase
programs that were not created or modified in connection with the Merger,
neither Merger Sub nor Parent nor any "RELATED PERSON" of Merger Sub or Parent
(as such term is defined by Treasury Regulation Section 1.368-1(e)(3)) will
repurchase or redeem any of the Parent Common Stock to be issued to the
stockholders of the Company in connection with the Merger;

        15. Except with respect to (i) payments of cash to stockholders of the
Company perfecting appraisal rights and (ii) payments of cash to stockholders of
the Company in lieu of fractional shares of Parent Common Stock, one hundred
percent (100%) of the stock of the Company outstanding immediately prior to the
Merger will be exchanged solely for Parent Common Stock. Thus, except as set
forth in the preceding sentence, Merger Sub and Parent intend that no
consideration be paid or received (directly or indirectly, actually or
constructively) for stock of the Company other than Parent Common Stock;

        16. The total fair market value of all consideration other than Parent
Common Stock received by stockholders of the Company in the Merger (including,
without limitation, cash paid to stockholders of the Company perfecting
appraisal rights) will be less than ten percent (10%) of the aggregate fair
market value of stock of the Company outstanding immediately prior to the
Merger;

        17. The fair market value of the Parent Common Stock received by each
stockholder of the Company will be approximately equal to the fair market value
of the stock of the Company surrendered in exchange therefor, and the aggregate
consideration received by stockholders of the Company in exchange for their
stock of the Company will be approximately equal to the fair market value of all
of the outstanding shares of stock of the Company immediately prior to the
Merger;

                                       3.



        18. Each of Merger Sub, Parent, the Company and each stockholder of the
Company will each pay separately his, her or its own expenses relating to the
Merger;

        19. There is no intercorporate indebtedness existing between Parent and
the Company or between Merger Sub and the Company that was issued, acquired or
will be settled at a discount as a result of the Merger, and Parent will assume
no liabilities of the Company or any stockholder of the Company in connection
with the Merger;

        20. The terms of the Merger Agreement and the agreements related thereto
are the product of arm's length negotiations;

        21. None of the compensation received by any stockholder-employee of the
Company will be separate consideration for, or allocable to, any of their shares
of stock of the Company; none of the shares of Parent Common Stock received by
any stockholder-employee of the Company will be separate consideration for, or
allocable to, any employment agreement or any covenants not to compete; and the
compensation paid to any stockholder-employee of the Company will be for
services actually rendered and will be commensurate with amounts paid to third
parties bargaining at arm's length for similar services;

        22. The payment of cash in lieu of fractional shares of Parent Common
Stock is solely for the purpose of avoiding the expense and inconvenience to
Parent of issuing fractional shares and does not represent separately
bargained-for consideration. The total cash consideration that will be paid in
the transaction to the Company stockholders instead of issuing fractional shares
of Parent Common Stock will not exceed one percent (1%) of the total
consideration that will be issued in the transaction to the Company stockholders
in exchange for their shares of Company Capital Stock. The fractional share
interests of each Company stockholder will be aggregated, and no Company
stockholder will receive cash in an amount equal to or greater than the value of
one full share of Parent Common Stock;

        23. With respect to each instance, if any, in which shares of stock of
the Company have been purchased by a stockholder of Parent (a "STOCKHOLDER")
during the Pre-Merger Period (a "STOCK PURCHASE"): (i) the Stock Purchase was
made by such Stockholder not as a representative of Parent; (ii) the purchase
price paid by such Stockholder pursuant to the Stock Purchase was not advanced,
and will not be reimbursed, either directly or indirectly, by Parent; (iii) at
no time was such Stockholder or any other party required or obligated to
surrender to Parent the Company Capital Stock acquired in the Stock Purchase,
and neither such Stockholder nor any other party will be required to surrender
to Parent the Parent Common Stock for which such shares of stock of the Company
will be exchanged in the Merger; and (iv) the Stock Purchase was not a formal or
informal condition to consummation of the Merger; and

        24. Parent and Merger Sub are authorized to make all of the
representations set forth herein.

The undersigned recognize that (i) your opinions will be based on the
representations set forth herein and on the statements contained in the
Agreements and documents related thereto, and (ii) your opinions will be subject
to certain limitations and qualifications including that they may not be relied
upon if any such representations are not accurate in all material respects.

                                       4.



The undersigned recognize that your opinions will not address any tax
consequences of the Merger or any action taken in connection therewith except as
expressly set forth in such opinions.

RE:     MERGER PURSUANT TO THE AGREEMENT AND PLAN OF MERGER AND REORGANIZATION
        (THE "MERGER AGREEMENT"), DATED ___________, 1998, 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"), AND THE RELATED CERTIFICATE OF MERGER BETWEEN THE
        COMPANY AND MERGER SUB (THE "CERTIFICATE OF MERGER").

Gentlemen:

This letter is supplied to you in connection with your rendering of opinions
regarding certain federal income tax consequences of the Merger. Unless
otherwise indicated, capitalized terms not defined herein have the meanings set
forth in the Merger Agreement or the Certificate of Merger. The Merger Agreement
and the Certificate of Merger, including exhibits and schedules attached
thereto, are collectively referred to as the "AGREEMENTS."

After consulting with its counsel and auditors regarding the meaning of and
factual support for the following representations, the undersigned hereby
certifies and represents that the following facts are now true and will continue
to be true as of the Effective Time of the Merger and thereafter where relevant:

        1. Pursuant to the Merger, Merger Sub will merge with and into the
Company, and the Company will acquire all of the assets and liabilities of
Merger Sub. Specifically, the assets transferred to the Company pursuant to the
Merger will represent at least ninety percent (90%) of the fair market value of
the net assets and at least seventy percent (70%) of the fair market value of
the gross assets held by Merger Sub immediately prior to the Merger. In
addition, at least ninety percent (90%) of the fair market value of the net
assets and at least seventy percent (70%) of the fair market value of the gross
assets held by the Company immediately prior to the Merger will continue to be
held by the Company immediately after the Merger. For the purpose of determining
the percentage of the Company's and Merger Sub's net and gross assets held by
the Company immediately following the Merger, the following assets will be
treated as property held by Merger Sub or the Company, as the case may be,
immediately prior but not subsequent to the Merger: (i) assets disposed of by
the Company or Merger Sub (other than assets transferred from Merger Sub to the
Company in the Merger) prior to or subsequent to the Merger and in contemplation
thereof (including without limitation any asset disposed of by the 

                                       1.



Company, other than in the ordinary course of business, pursuant to a plan or
intent existing during the period ending on the Effective Time of the Merger and
beginning with the commencement of negotiations (whether formal or informal)
with Parent regarding the Merger (the "PRE-MERGER PERIOD"); (ii) assets used by
the Company or Merger Sub to pay stockholders perfecting appraisal rights or
other expenses or liabilities incurred in connection with the Merger and (iii)
assets used to make distribution, redemption or other payments in respect of
stock of the Company or rights to acquire such stock (including payments treated
as such for tax purposes) that are made in contemplation of the Merger or that
are related thereto;

        2. Other than in the ordinary course of business or pursuant to its
obligations under the Agreements, the Company has made no transfer of any of its
assets (including any distribution of assets with respect to, or in redemption
of, stock) in contemplation of the Merger or during the Pre-Merger Period;

        3. The Company's principal reasons for participating in the Merger are
bona fide business purposes unrelated to taxes;

        4. On the Effective Time of the Merger, the Company will have no
outstanding equity interests other than those disclosed in Section 2.3 of the
Merger Agreement. At the time of the Merger, except as specified in the Merger
Agreement, the Company will have no outstanding warrants, options, or
convertible securities or any other type of right outstanding pursuant to which
any person could acquire shares of the Company Capital Stock or any other equity
interest in the Company, other than those disclosed in Section 2.3 of the Merger
Agreement or the Disclosure Schedule with respect thereto;

        5. In the Merger, shares of stock of the Company representing "CONTROL"
of the Company will be exchanged solely for shares of voting stock of Parent. At
the Effective Time of the Merger, there will exist no rights to acquire the
Company Capital Stock or to vote (or restrict or otherwise control the vote of)
shares of stock of the Company which, if exercised, would affect Parent's
acquisition and retention of control of the Company. For purposes of this
paragraph, shares of the stock of Company exchanged in the Merger for cash and
other property (including, without limitation, cash paid to stockholders of the
Company perfecting appraisal rights, if any, or in lieu of fractional shares of
Parent Common Stock) will be treated as shares of stock of the Company
outstanding on the date of the Merger but not exchanged for shares of voting
stock of Parent. As used in this letter, "CONTROL" shall consist of direct
ownership of shares of stock possessing at least eighty percent (80%) of the
total combined voting power of shares of all classes of stock entitled to vote
and at least eighty percent (80%) of the total number of shares of all other
classes of stock of the corporation. For purposes of determining Control, a
person shall not be considered to own shares of voting stock if rights to vote
such shares (or to restrict or otherwise control the voting of such shares) are
held by a third party (including a voting trust) other than an agent of such
person;

        6. The total fair market value of all consideration other than shares of
Parent Common Stock received by stockholders of the Company in the Merger
(including, without limitation, cash paid to Company stockholders perfecting
appraisal rights or in lieu of fractional shares of Parent Common Stock) will be
less than ten percent (10%) of the aggregate fair market value of shares of
stock of the Company outstanding immediately prior to the Merger;

                                       2.



        7. The Company has no plan or intention to issue additional shares of
stock after the Merger, or take any other action, that would result in Parent
losing Control of the Company;

        8. Except for transfers described in both Section 368(a)(2)(C) of the
Code and Treasury Regulation Section 1.368-2(j)(4), the Company has no plan or
intention to sell or otherwise dispose of any of its assets or of any of the
assets acquired from Merger Sub in the Merger except for dispositions made in
the ordinary course of business or to pay expenses incurred by the Company
pursuant to the Merger;

        9. The Company intends to continue its historic business or use a
significant portion of its historic business assets in a business following the
Merger;

        10. The liabilities of the Company have been incurred by the Company in
the ordinary course of its business;

        11. The fair market value of the Company's assets will, on the Effective
Time of the Merger, exceed the aggregate liabilities of the Company plus the
amount of liabilities, if any, to which such assets are subject;

        12. The Company is not and will not be on the Effective Time of the
Merger an "INVESTMENT COMPANY" within the meaning of Section 368(a)(2)(F)(iii)
and (iv) of the Code;

        13. The Company is not and will not be on the Effective Time of the
Merger under the jurisdiction of a court in a Title 11 or similar case within
the meaning of Section 368(a)(3)(A) of the Code;

        14. The Company has made no extraordinary distributions within the
meaning of Temporary Federal Treasury Regulation Section 1.368-1T(e) with
respect to its stock, prior to and in connection with the Merger;

        15. The Company has not redeemed and no "RELATED PERSON" with respect to
the Company, as such term is defined by Treasury Regulation Section
1.368-1(e)(3), (without regard to Section 1.368-1(e)(3)(i)(a)), has purchased
any Company Capital Stock prior to and in connection with the Merger;

        16. Except with respect to (i) payments of cash to stockholders of the
Company in lieu of fractional shares of Parent Common Stock, and (ii) payments
of cash to stockholders of the Company perfecting appraisal rights, one hundred
percent (100%) of the shares of stock of the Company outstanding immediately
prior to the Merger will be exchanged solely for shares of Parent Common Stock.
Thus, except as set forth in the preceding sentence, the Company intends that no
consideration be paid or received (directly or indirectly, actually or
constructively) for shares of stock of the Company other than shares of Parent
Common Stock;

        17. The fair market value of the shares of Parent Common Stock received
by each stockholder of the Company will be approximately equal to the fair
market value of the shares of stock of the Company surrendered in exchange
therefor and the aggregate consideration received by stockholders of the Company
in exchange for their shares of stock of the Company will be 

                                       3.



approximately equal to the fair market value of all of the outstanding shares 
of stock of the Company immediately prior to the Merger;

        18. Each of Merger Sub, Parent, the Company and each stockholder of the
Company will each pay separately his, her or its own expenses relating to the
Merger;

        19. There is no intercorporate indebtedness existing between Parent and
the Company or between Merger Sub and the Company that was issued, acquired, or
will be settled at a discount as a result of the Merger; Parent will assume no
liabilities of the Company or any stockholder of the Company in connection with
the Merger;

        20. The terms of the Merger Agreement and the other agreements relating
thereto are the product of arm's length negotiations;

        21. None of the compensation received by any stockholder-employees of
the Company will be separate consideration for, or allocable to, any of their
shares of stock of the Company; none of the shares of Parent Common Stock
received by any stockholder-employees of the Company will be separate
consideration for, or allocable to, any employment agreement or any covenants
not to compete; and the compensation paid to any stockholder-employees of the
Company will be for services actually rendered and will be commensurate with
amounts paid to third parties bargaining at arm's length for similar services;

        22. With respect to each instance, if any, in which shares of stock of
the Company have been purchased by a stockholder of Parent (a "Stockholder")
during the Pre-Merger period (a "Stock Purchase"): (i) to the best knowledge of
the Company, (A) the Stock Purchase was made by such Stockholder on its own
behalf, rather than as a representative, or for the benefit, of Parent, (B) the
Stock Purchase was entered into solely to satisfy the separate interests of such
Stockholder and the seller, and (C) the purchase price paid by such Stockholder
pursuant to the Stock Purchase was the product of arm's length negotiations; and
(ii) the Stock Purchase was not a formal or informal condition to consummation
of the Merger; and

        23. The Company is authorized to make all of the representations set
forth herein.

        The undersigned recognizes that (i) your opinions will be based on the
representations set forth herein and on the statements contained in the
Agreements and documents related thereto, and (ii) your opinions will be subject
to certain limitations and qualifications including that they may not be relied
upon if any such representations are not accurate in all material respects.

Notwithstanding anything herein to the contrary, the undersigned makes no
representations regarding any actions or conduct of the Company pursuant to
Parent's exercise of control over the Company after the Merger.

                                       4.




The undersigned recognizes that your opinions will not address any tax
consequences of the Merger or any action taken in connection therewith except as
expressly set forth in such opinions.

                                             Very truly yours,


                                             IXYS CORPORATION,
                                             a Delaware corporation

                                    EXHIBIT G

                  REGISTRATION AND STOCKHOLDER RIGHTS AGREEMENT

Paradigm Technology, Inc., a Delaware corporation (the "Company"), and Asea
Brown Boveri A.G., a corporation formed under the laws of Germany and Asea Brown
Boveri, Inc., a Delaware corporation (collectively, the "Stockholder").


                                 R E C I T A L S

          WHEREAS, the Company, IXYS Corporation, a Delaware corporation
("IXYS") and Paradigm Enterprises, Inc., a Delaware corporation and wholly owned
subsidiary of the Company ("Merger Sub"), have entered into an Agreement and
Plan of Merger and Reorganization dated as of March 6, 1998 (the "Merger
Agreement"), pursuant to which Merger Sub will be merged with and into IXYS with
IXYS as the surviving corporation (the "Merger");

          WHEREAS, pursuant to the terms of the Merger, the Stockholder's shares
of common stock of IXYS, par value $0.001 per share, will be exchanged for the
right to receive shares of the common stock of the Company, par value $0.01;

          WHEREAS, in connection with the Merger and pursuant to the Merger
Agreement, the Company has agreed to provide the Stockholder with certain
registration rights as set forth herein.

     NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

     I. REGISTRATION RIGHTS. The Company covenants and agrees as follows:

          1.1 DEFINITIONS. For purposes of this Section 1:

               (a) The term "Act" means the Securities Act of 1933, as amended.

               (b) The term "Form S-3" means such form under the Act as in
effect on the date hereof or any registration form under the Act subsequently
adopted by the SEC which permits inclusion or incorporation of substantial
information by reference to other documents filed by the Company with the SEC.

               (c) The term "1934 Act" shall mean the Securities Exchange Act of
1934, as amended.



               (d) The term "register," "registered," and "registration" refer
to a registration effected by preparing and filing a registration statement or
similar document in compliance with the Act, and the declaration or ordering of
effectiveness of such registration statement or document.

               (e) The term "Registrable Securities" means (i) all or any shares
of Common Stock received by the Stockholder in connection with the Merger (all
such Shares, the "Merger Shares"), (ii) any shares of Common Stock issued as a
dividend or distribution with respect to, or in exchange for, or in replacement
of, the Merger Shares, and (iii) any shares of Common Stock issuable upon the
conversion or exercise of any warrant or right.

               (f) The term "SEC" shall mean the Securities and Exchange
Commission.

          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.

               (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 agreement in
customary form with the underwriter or underwriters selected for such
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 has been declared or ordered effective, or more than two such
     registrations have been declared or ordered effective overall;

                    (ii) During the period starting with the date thirty (30)
     days prior to the Company's good faith estimate of the date of filing of,
     and ending on a date
                                       2



     ninety (90) days after the effective date of, a registration subject to
     Section 1.3 hereof; provided that the Company is actively employing in good
     faith all reasonable efforts to cause such registration statement to become
     effective;

                    (iii) If the Stockholder proposes to dispose of shares of
     Registrable Securities that may be immediately registered on Form S-3
     pursuant to a request made pursuant to Section 1.10 below; or

                    (iv) if the Company shall furnish to the Stockholder a
     certificate signed by the Chairman of the Board 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
     registration statement to be effected at such time, in which event the
     Company shall have the right to defer such filing for a period of not more
     than ninety (90) days after receipt of the request of the Stockholder;
     provided that such right to delay a request, whether pursuant to this
     Section 1.2 or Section 1.10, shall be exercised by the Company not more
     than once in any twelve (12) month period.

          1.3 COMPANY REGISTRATION.

               (a) If (but without any obligation to do so) the Company proposes
to register (including for this purpose a registration effected by the Company
for stockholders other than the Stockholder) any of its stock or other
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.

               (b) The Company shall have the right to terminate or withdraw any
registration initiated by it under this Section 1.3 prior to the effectiveness
of such registration whether or not the Stockholder has elected to include
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:

                                       3



               (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; 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.

                                       4



               (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 than
pursuant to Section 1.3) and related filings or qualifications, including
(without limitation) all registration, filing and qualification fees, 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 first such
registration, (ii) the fees and disbursements of any counsel retained by it in
connection with any such registrations, and (iii) any underwriting discounts or
commissions payable with respect to any Registrable Securities sold by it.

          1.6 EXPENSES OF COMPANY REGISTRATION. The Company shall bear and pay
all 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 Section 1.11), including (without limitation) all registration,
filing, and 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.

                                       5



          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 required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act,

                                       6



any state securities law or any rule or regulation promulgated under the Act or
the 1934 Act or any state 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 any Violation, in each case
to the extent (and only to the extent) that 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

                                       7



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 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;

                                       8



               (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 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)
                                       9



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
                                       10



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 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

                                       11



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.

          2.4 NO ASSIGNMENT. The rights of the Stockholder under Sections 2.1
and 2.2 may not be assigned by the Stockholder without the consent of the
Company.

     III. REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company hereby represents and warrants to Stockholder as follows:

          3.1 REQUISITE CONSENTS; NONVIOLATION.

               (a) The Company has obtained all consents, approvals or
authorizations of any third party that would be required as a result of the

                                       12


               (b) The Company further represents and warrants that the
execution and delivery of this Agreement by the Company and the consummation of
the transactions contemplated by this Agreement will not (a) require the
consent, approval or authorization of any third party, other than the Obtained
Consents, or (b) constitute a default under, violate or conflict with or permit
any third party to modify, terminate, accelerate or rescind any term or
provision of, any contract, agreement, arrangement or understanding to which the
Company is a party or by which the Company is bound or to which the Company is
subject.

          3.2 AUTHORITY FOR AGREEMENT. All corporate and other proceedings
required to be taken by or on behalf of the Company to authorize the Company to
enter into and carry out this Agreement have been duly and properly taken. This
Agreement has been duly executed and delivered by the Company and is valid and
binding upon the Company, subject as to enforceability, to bankruptcy,
insolvency, reorganization and other laws of general applicability relating to

IXYS Corporation

Santa Clara, CA 95054
Attn:  Dr. Nathan Zommer

        Re:    Agreement and Plan of Merger and Reorganization

Ladies and Gentlemen:

        We have acted as counsel to Paradigm Technology, Inc., a Delaware
corporation (the "Parent") and Paradigm Enterprises, Inc., a Delaware
corporation (the "Merger Sub") in connection with the Agreement and Plan of
Merger and Reorganization (the "Merger Agreement"), dated as of March __, 1998,
by and among the Parent, Merger Sub and IXYS Corporation (the "Company"). This
opinion is provided to you in satisfaction of the requirement set forth in
Section 8.8(d) of the Merger Agreement. Terms not otherwise defined herein have
the meanings given to them in the Merger Agreement.

        We have served as counsel to the Parent since 1994, although our
representation has been limited to those matters referred to us by the Parent.
We have represented Merger Sub since its formation. We have also acted as
counsel to Paradigm and Merger Sub with respect to the preparation, execution
and delivery of the Merger Agreement, and are familiar with the proceedings
taken by the Parent and Merger Sub in connection therewith.

        In connection with this opinion, we have examined executed copies of the
Merger Agreement (including exhibits and schedules thereto), records of
proceedings of the directors and stockholders of the Parent and Merger Sub, the
Certificate of Incorporation and Bylaws of the Parent and Merger Sub and such
other documents and certificates of public officials and representatives of the
Parent and Merger Sub as we have deemed necessary as a basis for the opinions
expressed herein. As to questions of fact material to such opinions, we have,
when relevant facts were not independently established, relied solely upon
certificates, statements and representations of the officers of the Parent and
Merger Sub.

        Based upon and subject to the qualifications set forth herein, it is our
opinion that:

        1. The Parent is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of Delaware, and has full requisite
corporate power and authority to conduct its business as and to the extent now
conducted and to own, use and lease its assets and properties. The Parent is
qualified to transact business in the State of California.

        2. The Merger Sub is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Delaware, and has full
requisite corporate power and authority to conduct its business as and to the
extent now conducted and to own, use and lease its assets and properties.

        3. The Parent has full corporate power and authority to enter into the
Merger Agreement, to perform its obligations thereunder and to consummate the
transactions contemplated thereby. The execution, delivery and performance of
the Merger Agreement by Parent, and the consummation by the Parent of the
transactions contemplated thereby, have been duly and validly approved by the
Board of Directors of the Parent and by the stockholders of the Parent. The
Merger Agreement has been duly and validly authorized, executed and delivered by
the Parent and constitutes the legal, valid and binding obligation of the Parent
enforceable against the Parent in accordance with its terms.

        4. The Merger Sub has full corporate power and authority to enter into
the Merger Agreement, to perform its obligations thereunder and to consummate
the transactions contemplated thereby. The execution, delivery and performance
of the Merger Agreement by the Merger Sub, and the consummation by the Merger
Sub of the transactions contemplated thereby, have been duly and validly
approved by the Board of Directors of the Merger Sub and by the stockholder of
the Merger Sub. The Merger Agreement has been duly and validly authorized,
executed and delivered by the Merger Sub and constitutes the legal, valid and
binding obligation of the Merger Sub enforceable against the Merger Sub in
accordance with its terms.

        5. The execution, delivery and performance of the Merger Agreement and
the transactions contemplated thereby by the Parent do not violate any provision
of the Restated Certificate of Incorporation, as amended, to date, or By-Laws,
as amended to date, of the Parent and do not violate or contravene any
governmental statute, rule or regulation applicable to the Parent.

        6. The execution, delivery and performance of the Merger Agreement and
the transactions contemplated thereby by the Merger Sub do not violate any
provision of the Certificate of Incorporation, as amended to date, or By-Laws,
as amended to date, of the Merger Sub and do not violate or contravene any
governmental statute, rule or regulation applicable to the Merger Sub.

        7. To our knowledge, there is no consent, approval, authorization,
order, registration, qualification or filing of or with any court or any
regulatory authority or other governmental body (either foreign or domestic)
required by the Parent or Merger Sub or with respect to their assets or
properties or otherwise for the consummation of the transactions contemplated by
the Merger Agreement that has not been obtained or waived, except for (i) such
consents, approvals, authorizations, registration or qualifications as may be
required under state securities or Blue Sky laws in connection with the offer
and sale of the Parent's Common Stock pursuant to the Merger Agreement, which
are not required to be made until after the Effective Time and (ii) acceptance
for filing of the Certificate of Merger by the Secretary of State of Delaware.

        8. To our knowledge, other than as set forth in the Merger Agreement
(including the Parent Disclosure Schedule), there are no actions, suits,
arbitrations or proceedings pending or overtly threatened against the Parent or
any of its assets or properties which seek to prohibit, restrain or enjoin the
transactions contemplated by the Merger Agreement and the Certificate of Merger.

        9. The Form S-4 Registration Statement has become effective under the
Securities Act, and to our knowledge, no stop order proceeding with respect
thereto has been instituted or threatened by the Securities and Exchange
Commission.

        10. The shares of the Parent Common Stock to be issued in connection
with the Merger will be, upon filing of the Certificate of Merger with the
Secretary of State of the State of Delaware and upon issuance pursuant to the
terms of the Merger Agreement, be duly authorized, validly issued, fully paid
and nonassessable and free of preemptive or similar rights contained in the
Certificate of Incorporation or By-Laws of the Parent. Assuming the Company
Options to be assumed by the Parent in the Merger were valid and binding
obligations of the Company prior to the assumption thereof by the Parent, such
Company Options will represent valid and binding obligations of the Parent when
assumed by the Parent in accordance with the terms of the Merger Agreement. The
shares of the Parent Common Stock issuable upon exercise of the Company Options,
when issued in accordance with the respective terms of such Company Options,
will be duly authorized, validly issued, fully paid and nonassessable.

        The foregoing opinions are subject to such matters as are set forth in
the Merger Agreement and the following qualifications:

        Our opinions in paragraphs 3, 4 and 10 above are subject to and limited
by: (i) the effect of bankruptcy, insolvency, reorganization, receivership,
conservatorship, arrangement, fraudulent transfer, moratorium or other similar
laws affecting or relating to the rights of creditors generally; (ii) the rules
governing the availability of specific performance, injunctive relief or other
equitable remedies and general principles of equity, regardless of whether
considered in a proceeding in equity or at law; (iii) the effect of applicable
court decisions invoking statutes or principles of equity, which have held that
certain covenants and provisions of agreements are unenforceable where the
breach of such covenants or provisions imposes restrictions or

______________ ___, 1998

burdens upon an obligor, and it cannot be demonstrated that the enforcement of
such restrictions or burdens is necessary for the protection of the creditors,
or which have held that the creditor's enforcement of such covenants or
provisions under the circumstances would violate the creditor's covenants of
good faith and fair dealing implied under law; (iv) limitations under federal or
state securities laws or public policy relating thereto with respect to rights
to indemnification or contribution; and (v) the effect of statutes and rules of
law which cannot be waived prospectively by an obligor. We express no opinion
regarding Section 9.3 of the Merger Agreement.

        We have assumed the genuineness of all signatures, the authenticity of
all documents submitted to us as originals, the conformity to original documents
of all documents submitted to us as photostatic or telecopied originals, the
legal capacity of all natural persons, and, as to documents executed by entities
other than the Parent or Merger Sub, that each such entity has complied with any
applicable requirement to file returns and pay taxes under applicable California
law and had the power to enter into and perform its obligations thereunder, and
that such documents have been duly authorized, executed and delivered by, and
are binding upon and enforceable against, such entities.

        We assume that you know of no agreements, understandings or negotiations
between the parties not set forth in the Merger Agreement that would modify the
terms or rights and obligations of the parties thereunder.

        This opinion is limited in all respects to matters governed by the laws
of the State of California, the General Corporation Law, as amended, of the
State of Delaware and the laws of the United States, and we express no opinion
concerning the laws or regulations of any other jurisdiction or jurisdictions.
We express no opinion as to the effect on the transaction of the antitrust laws
of California, Delaware or the United States.

        Whenever a statement herein is qualified by "to our knowledge," "we are
not aware" or similar phrase, it is limited to specific matters referred to us
by the Parent or Merger Sub, and indicates that in the course of our
representation of the Parent or Merger Sub no information that would give us
current actual knowledge of the inaccuracy of such statement has come to the
attention of the attorneys in this firm who have rendered legal services in
connection with this transaction. We have not made any special or independent
investigation to determine the accuracy of such statement, except as expressly
described herein.

        This opinion is being delivered to you by us as counsel to the Parent
and Merger Sub and may not be delivered to or relied upon by any other person
without our express written approval.

                                             Very truly yours,


E-05247
