Dear Shareholder:

   
         You are cordially invited to attend the Annual Meeting of Shareholders

offices of the Company, Suite 270, 2105 Hamilton Avenue, San Jose, California

the appointment of independent auditors, the Shareholders will be considering
and acting upon a proposal to approve the sale of the Company's research and
development operations, including the assets and contracts related thereto, and
the grant of a non-exclusive license to the Company's intellectual property,
including the Company's rights in patents, technology and software, pursuant to
the terms and conditions of the Agreement for Purchase and Sale of Assets, dated
as of March 29, 1996, by and between Read-Rite Corporation ("Read-Rite") and the
Company (the "Proposed Transaction").
    

         Details of the Proposed Transaction and the other proposals and other
important information concerning the Company appear in the accompanying Proxy

FAVOR OF APPROVING THE PROPOSED TRANSACTION.

         YOUR VOTE IS VERY IMPORTANT TO THE COMPANY.

         As a condition to consummating the Proposed Transaction, the Proposed
Transaction must be approved by the affirmative vote of holders of at least a

                                    ( DATE )

         THIS PROXY STATEMENT IS FURNISHED TO THE HOLDERS OF COMMON STOCK AND
PREFERRED STOCK OF CENSTOR CORP. (THE "COMPANY" OR "CENSTOR") IN CONNECTION WITH
THE SOLICITATION BY THE BOARD OF DIRECTORS OF THE COMPANY OF PROXIES IN THE FORM
ENCLOSED TO BE VOTED AT AN ANNUAL MEETING OF SHAREHOLDERS OF THE COMPANY TO BE
HELD AT THE COMPANY'S OFFICES, SUITE 270, 2105 HAMILTON AVENUE, AT 11 A.M. ON
(DATE), 1996 (THE "ANNUAL MEETING"). THIS PROXY STATEMENT AND THE ACCOMPANYING
FORM OF PROXY ARE BEING MAILED TO THE SHAREHOLDERS ON OR ABOUT ( DATE ), 1996
AND THE COMPANY IS BEARING THE COST OF THIS SOLICITATION.
    

                             PURPOSE OF THE MEETING

         At the Annual Meeting, the Shareholders of the Company (the
"Shareholders") will be asked to consider and act upon the following proposals:

         1. To elect five (5) directors to serve for the ensuing year and until
         their successors are elected;

         2. To ratify the appointment of Ernst & Young LLP as the Company's
         independent auditors for the fiscal year ending June 30, 1996;

         3. To approve the sale of the Company's research and development
         operations, including the assets and contracts related thereto, and the
         grant of a non-exclusive license to the Company's intellectual
         property, including the Company's rights in patents, technology and
         software, pursuant to the terms and conditions of the Agreement for
         Purchase and Sale of Assets, dated as of March 29, 1996 (the "Asset
         Sale Agreement"), by and between Read-Rite Corporation ("Read-Rite")
         and the Company and the transactions contemplated thereby
         (collectively, the "Proposed Transaction"); and

         4. To transact such other business as may properly come before the
         Annual Meeting and any adjournment thereof.

                                  VOTING RIGHTS

   
         Shareholders of record of the Company as of the close of business on
May 31, 1996 have the right to receive notice of and to vote at the Annual
Meeting. On May 31, 1996, the Company had issued and outstanding 24,291,151
shares of capital stock entitled to vote, consisting of 9,303,344 shares of
Common Stock, 6,617,299 shares of Series A Preferred Stock and 8,370,508 shares
of Series B Preferred Stock. Each share of Common Stock, Series A Preferred
Stock and Series B Preferred Stock is entitled to one vote. For action to be
taken at the Annual Meeting, the majority of the shares entitled to vote must be
represented at the meeting in person or by proxy.
    

         While the Company's Restated Articles of Incorporation authorize the
holders of the Company's Series B Preferred stock voting as a separate class to
elect one member of the Company's Board of Directors, to date, the holders of
the Series B Preferred Stock have not chosen to do so. Therefore, the holders of
Preferred Stock and Common Stock, voting together as a single class, will elect
all the members of the Board of Directors.
<PAGE>   6
         Every Shareholder voting for the election of directors may cumulate
such Shareholder's votes and give one candidate a number of votes equal to the
number of directors to be elected multiplied by the number of votes to which the
Shareholder's shares are entitled, or distribute the Shareholder's votes on the
same principle among as many candidates as the Shareholder thinks fit, provided
that votes cannot be cast for more than the number of directors to be elected.
However, no Shareholder shall be entitled to cumulate votes unless such
candidate's name has been placed in nomination prior to the voting and the
Shareholder, or any other Shareholder, has given notice at the meeting prior to
the voting of his or her intention to cumulate his or her votes.

         Consummation of the Proposed Transaction requires the affirmative vote
of a majority of the shares of Common Stock and Preferred Stock voting together
as a single class. Certain Shareholders of the Company have granted Read-Rite an
irrevocable proxy to vote their shares in favor of approving the Proposed
Transaction. The Shareholders that granted such proxies currently hold a
majority of the outstanding shares of capital stock with voting rights and, if
such shares are voted in accordance with the proxy, the proposal to approve the
Proposed Transaction will be adopted by the Shareholders of the Company.

                                     PROXIES

         Proxies for use at the Annual Meeting are being solicited by the Board
of Directors of the Company from its Shareholders.

   
         Shares represented by properly executed proxies received by the Company
will be voted at the Annual Meeting in accordance with the instructions thereon.
Shares represented by executed proxies received by the Company with no
instructions will be voted in favor of all proposals set forth in the Notice of
Meeting. The Company intends to include abstentions as present or represented
for purposes of establishing a quorum for the transaction of business.
Abstentions are counted as votes against a proposal for purpose of determining
whether or not a proposal has been approved.
    

         Any person giving a proxy in the form accompanying this Proxy Statement
has the power to revoke it at any time before its exercise by (i) filing with
the Assistant Secretary of the Company a signed written statement revoking his
or her proxy or (ii) submitting an executed proxy bearing a date later than that
of the proxy being revoked. A proxy may also be revoked by attending the Annual
Meeting and voting in person. Attendance at the Annual Meeting will not by
itself constitute the revocation of a proxy.

         No persons have been authorized to give any information or to make any
representations other than those contained in this Proxy Statement in connection
with the solicitation of proxies and, if given or made, such information or
representations must not be relied upon as having been authorized by the Company
or any other person. This Proxy Statement does not constitute the solicitation
of a proxy in any jurisdiction to any person to whom it is not lawful to make
any such solicitation in such jurisdiction. The delivery of this Proxy Statement
does not, under any circumstances, create an implication that there has been no
change in the affairs of the Company since the date hereof or that the
information herein is correct as of any time subsequent to its date.

         ALL INFORMATION CONTAINED IN THIS PROXY STATEMENT RELATING TO READ-RITE
HAS BEEN PROVIDED BY READ-RITE AND THE COMPANY DOES NOT WARRANT THE ACCURACY OR
COMPLETENESS OF INFORMATION RELATING TO READ-RITE.

   
         The approximate date on which this Proxy Statement is being mailed to
the Company's Shareholders is (Date), 1996. This Proxy Statement is accompanied
by (a) the form of proxy card to be signed and returned in the enclosed
envelope, (b) the 1995 Annual Report of the Company, which consists of the
Company's Form 10-K for the year ended June 30, 1995, as amended by the Form
10-K/A Amendment No. 2 dated December 13, 1995, (c) a letter to the Shareholders
from the President, (d) the Company's quarterly report on Form 10-Q for the
quarter ended March 31, 1996, (e) pro-forma financial statements (included in
Appendix C to the Proxy Statement) and (f) Notice of Annual Meeting.

                           FORWARD LOOKING STATEMENTS

         The statements in this Proxy Statement that relate to future plans,
events or performance are forward-looking statements. Actual results could
differ materially due to a variety of important factors, including for example,
Read-Rite's ability to perform under the terms of the Proposed Transaction, the
Company's ability to develop its portfolio of licenses, failure of the Company's
licensees to perform under existing or future licenses, the development of
competing technology and the risks associated with protecting the Company's
intellectual property rights from adverse claims. Readers are cautioned not to
place undue reliance on these forward-looking statements, which speak only as of
the date hereof. The Company undertakes no obligation to publicly release the
result of any revisions to these forward looking statements that may be made to
reflect events or circumstances after the date hereof or to reflect the
occurrence of unanticipated events.

                                        thereto, on the closing date described
                                        in the Asset Sale Agreement (the
                                        "Closing").

                                        Additionally, as a condition to
                                        consummation of the Asset Sale

                                        property, including the Company's rights
                                        in patents, technology and software.

   
                                        The Company is not selling any of its
                                        assets relating to the technology,
                                        patents, know-how or any of its
                                        proprietary information. The Company
                                        will retain ownership of the technology
                                        and related patents developed during the
                                        past fourteen (14) years through the
                                        investment of $97.3 million in equity
                                        and debt financing through March 31,
                                        1996. After the consummation of the
                                        Proposed Transaction, the Company will
                                        no longer have technology development
                                        operations or the obligation to fund
                                        such operations. Such funding has
                                        recently required the Company to expend
                                        approximately $1.0 million per month;
                                        this represents two-thirds of the
                                        Company's total cash requirements. The
                                        Company currently owns 16 domestic
                                        patents, 10 foreign patents, has applied
                                        for an additional 10 patents and
                                        intends, through its own in-house patent
                                        attorney, to convert the remainder of
                                        its intellectual property into
                                        licensable patents and to develop
                                        royalty income from its licensees during
                                        the next several years. The Company is
                                        not selling any assets necessary to
                                        continue such licensing operations.
                                        Historically all of the Company's
                                        revenues have been derived from the
                                        grant of licenses. See "Proposal 3: The
                                        Proposed Transaction - Background"

                                        the Proposed Transaction be approved by
                                        the affirmative vote of at least the

                                        Certain Shareholders of the Company have
                                        granted Read-Rite an irrevocable proxy
                                        to vote their shares in favor of
                                        approving the Proposed Transaction;
                                        these Shareholders are: Brentwood

                                        Cottrell. In aggregate, such
                                        Shareholders' common equivalent voting
                                        shares exceed 14 million and represent
                                        approximately 58% of the total
                                        outstanding common equivalent voting
                                        shares of the Company. If Read-Rite
                                        votes in accordance with these proxies,
                                        approval of the Proposed Transaction is
                                        virtually guaranteed.

                                        require Read-Rite to pay an aggregate

                                        the Close) (the "Final Payment") (such
                                        amounts include payment for granting of

                                        subject to reduction in an amount equal
                                        to (a) 50% of the amount outstanding
                                        March 29, 1996 under a promissory note
                                        in the principal amount of $900,000 in
                                        favor of Read-Rite, plus (b) 50% of
                                        certain employee compensation expenses
                                        accrued or paid by Read-Rite through
                                        March 29, 1996, plus (c) 50% of accrued
                                        but unpaid expenses of the Company from
                                        February 2, 1996 through March 29, 1996,
                                        less (d) certain prepaid expenses of the
                                        Company outstanding on March 29, 1996,
                                        less (e) certain expenses of the Company
                                        incurred through the Closing, including
                                        accounting, legal and other expenses
                                        related to the Proposed Transaction
                                        ("Seller Expenses"). Seller Expenses are
                                        defined and discussed in greater detail
                                        in the section entitled " Proposal 3:
                                        The Proposed Transaction - Purchase
                                        Price" (page 22). The downward
                                        adjustments to the purchase price
                                        through March 29, 1996 are estimated to
                                        be $857,000.
    

                                        The Final Payment is subject to
                                        reduction for any claims by Read-Rite
                                        for damages in the event the Company
                                        breaches the Asset Sale Agreement or
                                        License Agreement.

   
                                        In addition, Read-Rite will lend to the
                                        Company up to $1,550,000 to finance the
                                        Company's operations and certain ongoing
                                        business expenses through the Closing
                                        ("Bridge Notes"). Amounts borrowed from
                                        Read-Rite under the Bridge Notes that
                                        are used to pay, or are accrued for,
                                        expenses after March 29, 1996 and before
                                        the Closing related to the assets and
                                        contracts transferred to Read-Rite
                                        (including for example, equipment lease
                                        payments, building rent, utilities and
                                        other related expenses) will be forgiven
                                        as of the Closing. As of May 31, 1996
                                        the balance owing on the Bridge Notes is
                                        $ 1,300,000, excluding interest. It is
                                        anticipated that the Company will
                                        require the entire $1,550,000 of the
                                        Bridge Notes to be drawn down by the
                                        Close.
    

                                        Of the net proceeds from the Proposed
                                        Transaction, the Company expects to use
                                        approximately $ 6.4 million to pay down
                                        obligations estimated to be due as of
                                        the

                                        for payment to Denki Kagaku Kogyo Co.,
                                        Ltd. ("Denka") by July 31, 1996, and
                                        $1.0 million plus accrued interest, at
                                        11%, for payment of obligations to
                                        certain Shareholders who have loaned the
                                        Company operating funds, of which
                                        $546,675, plus accrued interest, is due
                                        at the Closing and the remainder due
                                        nine months after the Closing. The
                                        remainder of the proceeds, if any, will
                                        be used for general working capital
                                        purposes with respect to the Company's
                                        remaining business operations. The
                                        Company has no present intention to pay
                                        any dividend to Shareholders or to
                                        otherwise distribute to its Shareholders
                                        any proceeds received from the Proposed
                                        Transaction.

ADVISER                                 Gehr International, has rendered a
                                        written opinion that the consideration
                                        to be received by the Company in the
                                        Proposed Transaction is fair from a

                                        agreements, covenants and conditions
                                        required to be performed under the Asset

                                        Sale Agreement are contingent upon
                                        Read-Rite and the Company consummating
                                        the License Agreement.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         The Company has entered into the following transactions with its
officers and directors since July 1, 1994:

         In September 1990, Harold J. Hamilton, a retired executive officer and
a past director of the Company, exercised stock options as to 244,821 shares of
the Company's Common Stock and, in lieu of payment to the Company for such
exercise, Mr. Hamilton delivered to the Company a promissory note in the
principal amount of $71,500. The note, the total principal amount of which is
still outstanding, was subsequently amended to change the interest rate,
currently bears interest at the rate of 5.38% per annum and is due September 21,
2000.

         In September 1990, Edwin V.W. Zschau, a current director of the
Company, exercised stock options as to 283,092 shares of the Company's Common
Stock and in lieu of payment to the Company for such exercise, Dr. Zschau
delivered to the Company a promissory note in the principal amount of $82,500.
The note, the total principal amount of which is still outstanding, was
subsequently amended to change the interest rate, currently bears interest at
the rate of 5.38% per annum and is due April 23, 1997.

         The Company's Bylaws provide that the Company is required to indemnify
its officers and directors to the fullest extent permitted by California law,
including those circumstances in which indemnification would otherwise be
discretionary, and that the Company is required to advance expenses to its
officers and directors as incurred. Further, the Company has entered into
indemnification agreements with its officers and directors. The Company believes
that its charter and bylaw provisions and indemnification agreements are
necessary to attract and retain qualified persons as directors and officers.

         The Company believes that all of the transactions set forth above were
made on terms no less favorable to the Company than could have been obtained
from unaffiliated third parties. All future transactions between the Company and
its officers, directors, principal Shareholders and affiliates will be approved
by a majority of the Board of Directors, including a majority of the independent
and disinterested outside directors on the Board of Directors, and will be on
terms no less favorable to the Company than could be obtained from unaffiliated
third parties.

<PAGE>   18
         In December 1995, Edwin V.W. Zschau, a current director of the Company,
entered into a one year consulting agreement with the Company, whereby the
Company would pay Dr. Zschau $7,500 per month for up to three days service per
month to help develop and implement the Company's financing strategy as well as
for participation as a member of the Company's Board of Directors. Dr. Zschau
subsequently worked 30 days on behalf of the Company during the period December
1995 through March 1996, culminating with the Company entering into a Letter of
Intent with Read-Rite. The Company's Board agreed to modify this agreement to
pay Dr. Zschau $75,000 for the 30 days of work through March 31, 1996, and to
terminate any future payments for consulting on financial strategy issues. Dr.
Zschau will be paid for attendance at Board of Director's meetings (See
"Director Compensation".)

   
         On January 31, 1996 and subsequently amended on April 2, 1996, the
Company's Board of Directors approved a six month performance bonus
(approximately $137,500) to be paid semi-monthly commencing April 23, 1996, for
Garrett A. Garrettson. Dr. Garrettson has resigned as President and Chief
Executive Officer effective April 22, 1996. See "Proposal 1: Election of
Directors" (pages 9-10).

COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT

         Section 16(a) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), requires the Company's directors and executive officers, and
persons who own more than ten percent of a class of a registered class of the
Company's equity securities, to file reports of ownership on Form 3 and changes
in ownership on Form 4 or 5 with the Securities and Exchange Commission and the
National Association of Securities Dealers. Such officers, directors and ten
percent Shareholders are also required by Securities and Exchange Commission
rules to furnish the Company with copies of all Section 16(a) forms that they
file.

         Based solely on its review of copies of such reports received or
written representations from certain reporting persons, the Company believes
that, during the fiscal year ended June 30, 1995, there has been no failure by
any of its officers, directors or ten percent Shareholders to file on a timely
basis any reports required by Section 16(a).
    

                                   PROPOSAL 2:

               RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

         The Board of Directors has appointed Ernst & Young LLP, the Company's
independent auditors, to audit the Company's consolidated financial statements
for its fiscal year ending June 30, 1996, and further recommends that
Shareholders vote for ratification of such appointment. In the event of a
negative vote on such ratification, the Board of Directors will reconsider its
selection. The Board of Directors recommends that Shareholders vote "FOR"
approval and ratification of such selection.

         A representative of Ernst & Young LLP is expected to be available at
the Annual Meeting to make a statement if such representative desires to do so
and to respond to appropriate questions.

                                   PROPOSAL 3:

                            THE PROPOSED TRANSACTION

GENERAL

         Pursuant to the terms of the Asset Sale Agreement, the Company will
sell to Read-Rite most of its physical assets and assign its rights and
obligations to Read-Rite under its existing contracts related to its research
and development operations, including its lease agreement for its facilities at
530 Race Street, San Jose, California and its other lease agreements.

   
         The Company is not selling any of its assets relating to the
technology, patents, know-how or any of its proprietary information.
Consummation of the Asset Sale Agreement is conditioned upon the Company and
Read-Rite executing the License Agreement, which provides that the Company will
grant to Read-Rite a non-exclusive license covering the Company's intellectual
property, including the Company's rights in patents, technology and software.
The Company will retain ownership of the technology and related patents
developed during the past fourteen (14) years at a cost of $97.3 million in
equity and debt financing through March 31, 1996. The Company currently owns 16
domestic patents, 10 foreign patents, has an additional 10 U.S. patent
applications pending and intends, through its in-house patent attorney, to
convert the remainder of its intellectual property into licensable patents and
to develop royalty income from its licensees during the next several years.

    

         The Company is not selling any assets necessary to continue such
licensing operations. The detailed terms of, and conditions to, the Proposed
Transaction are contained in the Asset Sale Agreement. The statements made in
this Proxy Statement with respect to the terms of the Proposed Transaction and
related transactions are qualified in their entirety by reference to the more
complete information set forth in the Asset Sale Agreement, a copy of which is
attached to this Proxy Statement as Appendix A and which is incorporated herein
by reference.

BACKGROUND

   
         The Company was formed in 1981 to develop perpendicular recording
technology and to manufacture head and disk components for disk drives. The
Company subsequently shifted the focus of its development efforts from flying
perpendicular to contact perpendicular and most recently to longitudinal contact
recording technology. To date, the Company's principal source of revenue has
been license fees from disk drive manufacturers. While the Company's license
agreements typically provide for on-going royalty payments by the licensees
based upon sales of products incorporating the Company's technology, to date
none of the Company's licensees has commercialized products using the Company's
technology and the Company has received no recurring royalty revenue. The
Company has not been profitable in any fiscal period since inception and as of
March 31, 1996 had an accumulated deficit of $106.1 million. There can be no
assurance that the Company will achieve or sustain significant revenues or
profitability in the future.
    

         Since 1989, Censtor's primary strategy has been to develop critical
enabling technologies for the disk drive industry, protect those technologies
with a portfolio of patents as well as carefully protecting its proprietary
know-how, and to license its technology to disk drive manufacturers. Last year
Censtor attempted to provide, via its subsidiary, Contact Recording Technology,
Inc., ("CRT") an assured low cost source of heads to those licensees so that
products embodying the technology could be shipped in volume. The Company's goal
was to establish its technology as a main stream choice for high capacity disk
drives in general and small form factor disk drives in particular. As recently
as December 1995, Censtor's operating plans for 1996 calendar year called for
continued development of contact longitudinal recording technology and
improvements to the head/disk interface to reduce wear and improve storage
performance as well as delivering sample components in evaluation quantities to
existing and prospective licensees.

   
         During 1994 and 1995, Censtor developed a contact longitudinal head and
head-disk interface technology that enabled the Company to sell three additional
licenses to hard disk drive manufacturers, which generated interest among
several licensees in using the technology. Censtor worked diligently during 1995
to obtain financing from venture capital investors to secure the funds necessary
to complete the product engineering of Censtor's contact recording heads and to
put those components into volume production through CRT. The Company projected
1996 cash requirements totaling $35 -
    


                                       18

40 million to complete the development and to implement initial manufacturing
operations. This amount consisted of $10 - 15 million in new equity and $25
million in new equipment lease (debt) financing. The Company attempted
throughout calendar year 1995 to secure financing for such new manufacturing
operations. In so doing, Company's management and Board of Directors expended a
substantial amount of time and effort attempting to secure this financing.
During this time, Silicon Valley Bank loaned the Company $1.0 million based on
the expression of confidence by existing investors that they would invest $1.0
million. The Company was not successful in its efforts to raise the necessary
equity financing from existing investors. Most existing venture capital
investors could not invest new funds since these older partnerships had no
remaining uninvested funds.

         The Company received a non-binding offer for a portion of the necessary
equity financing in December 1995 from a venture capital firm that had not
previously invested in the Company. The firm subsequently elected not to make
the investment. The main reasons cited by this and other potential new investors
were their assessment of high financial risk, high future requirements for
additional equity financing and the possibility that the Company would not be
able to implement volume manufacturing quickly enough to satisfy potential
customer requirements. The Company was therefore unable to attract enough
venture capital to develop manufacturing operations.

         On January 2, 1996 existing investors loaned the Company $1.0 million
(referenced in the footnotes to the Financial Statements contained in the
Company's 10K/A Amendment No. 2), that they had previously committed. This
enabled the Company to continue operations until an alternative could be
obtained. The Company subsequently drew down on a weekly basis the entire $1.0
million.

         The Board of Directors held weekly telephonic Board of Directors
Meetings (starting in the third calendar quarter of 1995) which included
interested large Shareholders or their advisors, in which various financing
alternatives were discussed. Large investors (other than members of the Board of
Directors) who attended many of these meetings included Gary Morgenthaler
(Morgenthaler Partners) Jos Henkens (Advanced Technology Ventures), Renee Baker
(Nippon Enterprise Development Corporation), Richard Kramlich (New Enterprise
Associates), Bob Pavey (Morgenthaler Ventures), Bill Lamkin (Paine Webber, Inc.)
and David Dicioccio, Managing Director (Paine Webber, Inc.). Alternatives
including investment from U.S. venture capital companies, the sale of new
licenses, seeking investment from U.S. investment firms as well as in Japan,
Singapore and Taiwan and offering the sale of equity in the Company or its
manufacturing subsidiary to several magnetic head component manufacturing and
disk drive manufacturing companies. The Company's management team, as well as
the Board of Directors and large investors, pursued these alternatives through
telephone calls and domestic and international meetings over a period of seven
months. The Company approached its existing manufacturing partners, Daido Steel,
Marubeni, and Kabool to request them to increase their financial support through
additional investment. After several direct meetings with executives from these
three partners by mid January 1996 these partners declined to provide additional
direct investment to Censtor or its subsidiary (CRT). The Company was not able
to secure a firm commitment from any of these alternatives.

         In addition to the magnetic head and disk drive manufacturing companies
mentioned elsewhere, the Company held initial discussions with Pacven Walden
Management Co.; Allen Patricof & Co.; Helix Investments; U.S. Venture Partners;
Mohr Davidow Ventures; Integral Capital Partners; Burr, Egan, Deleage & Co.;
Singapore Technologies; Vertex Management (Singapore); Seagate; Silmag (France);
Economic Development Board of Singapore; Paine Webber; JAFCO (Japan); Arthur
Rock and Co.; G.E. Capital and others. Ultimately, these firms were not
interested in making an investment in the Company or its manufacturing
subsidiary.
    
         The delay and ultimate inability to attract sufficient equity from new
sources caused the Company to delay making the investments needed for both pilot
production and volume production of Censtor heads. At the same time, prospective
customers had shifted their implementation plans for Censtor's components from
niche market products to mainstream products, leading them to focus on
established high volume head manufacturers for their component supply rather
than the Company.

   
         In order to put Censtor's technology into high volume manufacturing in
1996, the Company also investigated modifying its planar head transducer design
and fabrication processes to produce a high density head using a pseudo-contact
slider (a flying head having a tail containing the recording element which drags
or intermittently contacts the media). Because of the Company's inability to
obtain the necessary financing to support this modification, the Company
abandoned this modification effort, (since the necessary equipment and technical
employees had been transferred to Read-

Rite as part of the Proposed Transaction, the Company does not currently plan to
develop manufacturing or production operations).

         These and other considerations led the Censtor Board of Directors in
early January 1996 to approve a major change in Censtor's business strategy and
to restructure its operations consistent with that new strategy. The Company
began in early January to concentrate its efforts to seek investment from its
licensees and potential customers. After meetings with top management at Maxtor
and Western Digital, Company management decided it should seek a business
relationship with established magnetic recording head suppliers. Western Digital
suggested to Read-Rite, a large independent manufacturer of magnetic recording
heads, that it should negotiate a business relationship with Censtor. The
Company's management and Board of Directors also contacted Silmag, AMC and FDK
(Japan) as alternative partners to Read-Rite. Solomon Brothers investment
bankers assisted in a business proposal to AMC whereby AMC would invest in or
buy Censtor or its manufacturing subsidiary. By the end of January 1996, no
positive interest was indicated by magnetic head manufacturing companies other
than Read-Rite and the Company began negotiations with Read-Rite in January 
1996.

         The meetings between Read-Rite and Censtor commenced on Monday, January
8, 1996 during which Dr. Garrettson, then President & CEO of the Company and
Cyril Yansouni, Chairman & Chief Executive Officer of Read-Rite met to discuss a
proposal that Dr. Garrettson had presented by telephone several days earlier.
After this meeting, Mr. Yansouni considered whether Read-Rite would be
interested in pursuing a business relationship with the Company. The Company and
Read-Rite held a subsequent meeting by telephone on Friday, January 12, 1996
attended by Dr. Garrettson, Russell Krapf (then Senior V.P. of the Company), Ed
Zschau, a member of the Company's Board of Directors along with Cyril Yansouni
and Rex Jackson, V.P. & General Counsel, both from Read-Rite. During this
telephonic meeting, Read-Rite expressed interest in negotiating a business
relationship whereby Read-Rite, although not willing to make a direct investment
in Censtor or its manufacturing subsidiary, was interested in acquiring most of
the physical assets and key employees of the Company. After further discussion
regarding Censtor's obligations and Read-Rite's valuation of the Company's
intellectual property, Read-Rite expressed an interest in licensing the
Company's technology, hiring the Company's Research and Development employees
and purchasing the specific equipment necessary to develop and manufacture
samples of magnetic heads incorporating the Company's technology. From January
15-28, 1996, Read-Rite and the Company held almost daily meetings, and the
Company was in daily contact with members of the Company's Board of Directors to
further evaluate a potential transaction and to negotiate terms of a proposed
transaction.

         On January 26, 1996, the Company held a telephonic Board of Directors
Meeting; the entire Board of Directors was present as well as representatives
from large investors including Paine Webber, New Enterprise Associates and
Nippon Enterprise Development, and in addition the Company's senior management,
Russell Krapf and Wil Cochran, consultant. The Company's outside counsel,
Michael G. Taylor of Wilson Sonsini Goodrich & Rosati also attended the meeting
by telephone. First the Board was notified by Dr. Garrettson that Read-Rite had
decided to proceed with negotiations with the Company. The board reviewed the
status of the Read-Rite negotiations as well as discussed the lack of any other
offers from any source and the Company's immediate need for a cash infusion to
sustain operations. The Board of Directors discussed that they had authorized by
resolution at the January 19, 1996 Board of Directors meeting, duly voted and
approved, for the Company's management and Ed Zschau, member of the Board, to
negotiate the Proposed Transaction. Dr. Garrettson gave further details of the
Company's position including that the Company was insisting that Read-Rite
assume all debt obligations on all physical assets of the company, thereby
significantly reducing the Company's cash requirements going forward.

         The negotiations between the Company and Read-Rite led to a Letter of
Intent being signed on February 2, 1996. After further negotiations regarding 
representations and warranties, assumption of the Company's leaselines by 
Read-Rite, Read-Rite loans to the Company to fund its operations until the
Close, personnel matters relating to the transferred employees to Read-Rite,
negotiations regarding the non-exclusive license for use of the Company's
intellectual property and other matters, the Company entered into the Asset Sale
Agreement on March 29, 1996 with Read-Rite.

The Proposed Transaction was reviewed by the Advisor (an independent
investment banking firm) to confirm its fairness to the Company and its
Shareholders.

Certain key elements of the proposed transaction are as follows:

    
         o        Read-Rite hired Censtor's product development team as of
                  February 5, 1996.

   
         o        Read-Rite will assume, as of the Closing, Censtor's lease
                  obligations for the building and equipment (approximately
                  $934,000 as of March 31, 1996) and will purchase the
                  used equipment (with a net book value of approximately
                  $125,601 as of March 31, 1996) that Censtor owns.
    

         o        Censtor will continue to pay the expenses in support of patent
                  prosecution and licensing activities.

   
         o        Read-Rite will have a non-exclusive paid-up license to
                  Censtor's technology invented prior to the date of the Closing
                  (know-how and patents, including patents from applications
                  that are pending or that may be filed in the future) to
                  manufacture or sell products to any customers world-wide.
    

         o        Censtor will retain ownership of all of its patents and
                  know-how existing as of the Closing and will continue to be
                  able to sell non-exclusive licenses to this intellectual
                  property to any company world-wide. Censtor will not have a
                  license to improvements to the technology that Read-Rite
                  invents.

         o        Censtor will continue to have reasonable access to former
                  Censtor employees for the purpose of prosecuting patents on
                  Censtor's inventions.

         o        For the intellectual property license and the used equipment,
                  Read-Rite will pay Censtor a total of approximately $9.0
                  million in four installments (see "Purchase Price below").

   
         Denka holds approximately $14.3 million of the Company's preferred and
convertible debt including accrued interest of $4.3 million as of March 31,
1996. In an unrelated transaction dated February 22, 1996, Denka and the Company
have entered into two agreements entitled "Amendment to Terms of Debentures" and
"Fifth Amendment to Manufacturing License Agreement" (collectively, the
"Amendments"). In the Amendment to Terms of Debentures, the Company is obligated
to pay $2.0 million against the outstanding accrued interest by July 31, 1996
and use its best efforts consistent with good business practices, subject to
certain conditions, to pay the remaining outstanding principal and accrued
interest on September 30, 1996. Notwithstanding the amounts paid, any
remaining interest shall be forgiven, on September 30, 1996. Additionally, in
consideration of executing and delivering the Fifth Amendment to Manufacturing
License Agreement, Denka has agreed to forgive the remaining principal balance
(due in September 1997 and January 1998) in return for increasing from 1% to 5%
Denka's portion of the royalties Censtor may receive from its present and
future licenses through the year 2001, and subject to the repayments above. An
analysis was performed by the Company that compared the amount of debt to be
forgiven by Denka with the amount of the increased royalty sharing that would be
paid by the Company to Denka. Based on the results of the analysis, the
Amendments were deemed to be in the interest of the Company by the Board of
Directors.


         As a result of the negotiations with Read-Rite and Denka, Censtor has
the opportunity to eliminate approximately $18.0 million in short and long term
obligations by using $6.4 million of the anticipated proceeds from the Proposed
Transaction to modify and partially satisfy obligations to Denka and to continue
operating as a licensing company with a patent portfolio that the Company
intends to grow in size, relevance and value. Removal of the obligations to
Denka, which are senior to the preferred stock, has been an essential part of
management's strategy to maximize Shareholder return from future licensing
revenues, since the interest being accrued on such obligations would be a
significant drain on future earnings.
    

                                       21
<PAGE>   26
   
         Prior to the Proposed Transaction, the Company has licensed its
technology on a non-exclusive basis to six companies for use in disk drives and
has signed a letter of intent with an additional licensee. These licenses have
so far returned the Company approximately $22.0 million in license fees and
non-refundable advance payments. The Company intends to focus its future
business after consummation of the Proposed Transaction on creating royalties
from these existing licenses and to negotiate new licenses with the remaining
companies in the disk drive industry based on the technology that the Company
has previously developed.

         Although the Read-Rite license diminishes the scope of Censtor's
licensing opportunity, it may increase royalties from the Company's licensing 
program because the license to Read-Rite may makes it possible for Read-Rite 
to bring products, based on Censtor technology, to market in high volume 
without Censtor having to make the investment to do so. By doing this, the 
Company's technology has a higher probability of being available in larger 
volume products in the market place. Other magnetic head manufacturers may 
want to license the Company's technology as a competitive response to Read-Rite.

PURCHASE PRICE

         The terms of the Proposed Transaction require Read-Rite to pay an
aggregate purchase price of $9,025,000, up to $6,525,000 of which will be paid
to the Company on the Closing, subject to certain adjustments (the "Initial
Payment"), and up to $2,500,000 (to be made in three payments, $250,000 on
November 15, 1996, $250,000 on December 13, 1996 and $2.0 million nine months
after Closing) (the "Final Payment") (such amounts include payment for granting
of the license pursuant to the License Agreement). The Initial Payment is
subject to reduction in an amount equal to (a) 50% of the amount outstanding as
of March 29, 1996 under a promissory note in the principal amount of $900,000 in
favor of Read-Rite, plus (b) 50% of certain employee compensation expenses
accrued or paid by Read-Rite through March 29, 1996, plus (c) 50% of accrued but
unpaid expenses of the Company from February 2, 1996 through March 29, 1996,
less (d) certain prepaid expenses of the Company outstanding on March 29, 1996,
less (e) certain expenses of the Company incurred through the Closing, including
accounting, legal and other expenses related to the Proposed Transaction
("Seller Expenses"). The adjustment to the Initial Payment is estimated to be
$857,000. Seller Expenses are limited in that they include legal and accounting
fees, patent filing and maintenance fees, salaries and benefits, workers'
compensation expenses, certain accrued interest and amounts owed to Read-Rite
and they must adhere to generally accepted accounting principles consistently
applied and be subject to the mutual review and agreement of Read-Rite and the
Company.
    

         The Final Payment is subject to reduction for amounts held back by
Read-Rite for damages in the event the Company breaches the Asset Sale Agreement
or License Agreement.

   
         In addition, Read-Rite will loan to the Company up to $1,550,000 to
finance the Company's operations and certain ongoing business expenses through
the Closing (the "Bridge Notes"). Amounts borrowed from Read-Rite under the
Bridge Notes that are used to pay, or are accrued for, expenses after March 29,
1996 and before the Closing, related to the Assets and contracts being
transferred to Read-Rite (including for example, equipment lease payments,
building rent, utilities and other related expenses) will be forgiven as of the
Closing.

ASSETS TO BE SOLD AND RETAINED BY THE COMPANY

         The assets of the Company to be sold to Read-Rite are non-income
producing and consist of all machinery, tooling, computer hardware, software and
other equipment and all furnishings, furniture, office supplies, leasehold
improvements, fixtures and other tangible property of the Company related to the
Company's research and development operations; prepaid expenses related to the
contracts to be assumed by Read-Rite; copies of all books, records, accounts,
correspondence and production records related to the assets to be sold and the
business related to the assets to be sold to Read-Rite; copies of all
manufacturing and technical documentation related to the assets to be sold to
Read-Rite or used by the Company in the conduct of the business related to the
assets to be sold to Read-Rite; and all other assets of the Company which are
not expressly retained by the Company. Assets retained by the Company include
the Company's cash

    

                                       22
<PAGE>   27

or cash equivalents; all know-how, intellectual property,
copyrights, trade secrets, patents and patent applications, that are owned,
controlled, acquired or otherwise licensable by the Company.

INTELLECTUAL PROPERTY TO BE RETAINED FOR LICENSING BY THE COMPANY

         Censtor will retain ownership of the intellectual property it has
developed over the years, including issued and pending patents, trade secrets,
software, know-how and trademarks. The Company currently owns approximately 16
United States patents and 10 foreign patents relating to the magnetic data
storage industry, with 10 domestic and numerous foreign patent applications
forthwith. Due in part to the Company's pioneering work in technologies such as
contact recording, it is believed that certain patents and/or patent
applications in the patent portfolio may have significance for the hard disk
drive industry.

         Read-Rite will be granted, as a part of the Proposed Transaction, a
non-exclusive license to the intellectual property as detailed in this document.
If Read-Rite is successful in volume production and sales of products
incorporating the Company's technology, the licensing value of the Company's
Intellectual Property may increase, as other entities may emulate Read-Rite and
move into technological areas covered by the Company's patents. The Company
hopes that may promote royalty payments by the Company's existing licensees as
well as encouraging the sale of new licenses. Moreover, divestiture of
manufacturing and sales operations by the Company may possibly strengthen the
Company's licensing position by reducing the need for cross-licensing and
decreasing the threat of an infringement countersuit upon enforcement of the
Company's patents.


   
DISPUTE RESOLUTION

         Management of Read-Rite and the Company will initially attempt to
resolve any material disagreements which might arise from implementing the
Proposed Transaction without assistance of an arbitrator or court. If this
proves unsuccessful, the Asset Sale Agreement dictates resolution by several
stages starting with good faith negotiation of the parties to the agreement and
culminating in binding arbitration under the commercial rules of the American
Arbitration Association. Any arbitration must be held in Santa Clara,
California.
    

SHAREHOLDER APPROVAL

         The Asset Sale Agreement requires Shareholder approval as a condition
to the Closing. The affirmative vote of a majority of the shares of the
Company's Common Stock and Preferred Stock outstanding at the Record Date is
therefore being sought to approve the Proposed Transaction.

CERTAIN INFORMATION CONCERNING READ-RITE

   
         Read-Rite, a public company, is one of the world's leading independent
manufacturer of recording heads, head gimbal assemblies (HGAs) and head stack
assemblies (HSAs) for disk drives and magnetoresistive heads for
quarter-inch-cartridge tape drives. With headquarters in Milpitas, California
and operations in Japan, Thailand, Malaysia, the Philippines and Singapore, the
company employs more than 24,000 people. For Fiscal 1995, Read-Rite reported
sales of more than $1.0 billion, during the most recent quarter (ending March
31, 1996), Read-Rite reported sales exceeding $258.0 million and profits of 
$1.3 million. Additionally, Read-Rite had $189.0 million in cash, cash
equivalents and short term securities at quarter end. Based on these results,
Company management believes that Read-Rite will be able to pay $9,025,000 of the
aggregate purchase price, to the Company. Read-Rite's Common Stock is traded on
the NASDAQ National Market. Prior to the Proposed Transaction, Read-Rite and the
Company had no affiliation.
    

OPINION OF FINANCIAL ADVISOR

   
         Von Gehr International (the "Advisor") was retained by the Company on
February 23, 1996 to render to the Company its opinion as to the fairness, from
a financial point of view, to the Company's Board of Directors and Shareholders
of the consideration to be received by the Company, pursuant to the Proposed
Transaction with Read-Rite. (See "Background" above on pages 18-23.) The Advisor
was not contacted by any other party concerning alternative transactions to the
Proposed Transaction. The Advisor has rendered a written opinion dated March 29,
1996 to the Company's Board of Directors to the effect that, as of such date,
the payment in cash by Read-Rite to the Company of the
    


                                       23
<PAGE>   28
Purchase Price and License Fee, as set forth in the Asset Sale Agreement and
License Agreement, respectively, are fair, from a financial point of view, to
the Shareholders of the Company. The full text of the written opinion of the
Advisor is attached to this Proxy Statement as Appendix B. Such opinion should
be read in its entirety for a description of the matters considered, assumptions
made and limits of review by the Advisor in arriving at its opinion.
   

         In arriving at its opinion, the Advisor reviewed a copy of the
definitive Asset Sale Agreement (including Exhibits thereto) and reviewed
historical financial information about the Company as well as product and other
information furnished to it by the Company. The Advisor also held discussions
with members of the Company's senior management regarding the historic and
current business operations and future risks and prospects of the Company,
including their expectation for certain strategic benefits of the Proposed
Transaction. (See "Recommendation of the Board of Directors" on page 5.) The
Advisor did not receive any material, including forecast information from
Read-Rite. As part of these discussions, the Advisor reviewed other types of
sale transactions contemplated by the Company over the preceding twenty-four
months and carefully reviewed the circumstances surrounding the contemplated
financing transaction that failed to close in December 1995 and subsequent
attempts to finance or sell the Company. Read-Rite's offer to acquire certain
assets of the Company was in fact the only offer received by the Company.

         In deriving its fairness opinion, the Advisor considered the value of
the Company and its assets by comparing the contemplated transactions with
Read-Rite to other technology licensing transactions including the Company's
prior licensing transactions and other financial studies, analyses and
investigations the Advisor deemed appropriate for purposes of its opinion.
Specifically the Advisor compared the benefits to be received by the Company
from Read-Rite as part of the contemplated transactions including cash payments,
assumption of liabilities and the cost avoidance of continuing to develop the
technology, as compared to the expected net present value of executing a
standard license agreement with Read-Rite and determined that the contemplated
transactions provided superior economic benefits. The Advisor compared the
benefits of the contemplated transactions with a variety of other technology
licensing agreements including Ethical's licensing transaction with Elan,
Imatron's licensing transaction with Siemens and Ecogen's licensing transaction
with Monsanto and determined that the considerations provided by Read-Rite to
the Company were favorable to the other transactions reviewed, based on a ratio
of anticipated future profits to front end cash payments. Additionally, the
Advisor compared the ratio of transaction considerations provided and related
transaction expenses with that of 33 technology licensing transactions and
determined that the ratio of the contemplated transactions materially exceeded
the mean of the 33 transactions considered. In considering alternatives to
maximize Shareholder value, the Advisor also analyzed liquidating the Company as
an alternative to sale of certain of its research and development assets to
Read-Rite. The Advisor concluded that the cost of an orderly liquidation of
these assets of the Company would decrease substantially the resulting value to
the Shareholders compared to that realizable for the Proposed Transaction. Based
on all the above and the prospect of continuing operating losses, the Advisor
concluded that consummating the Transaction as quickly as possible would
maximize Shareholder value. In the opinion rendered, the Advisor did not provide
a valuation range for the Proposed Transaction.


         The Advisor considered a wide range of alternative methods to validate
the fairness of the transaction through analysis. In researching recent
transactions, no other deals were identified that were directly comparable to
the transaction contemplated and after careful consideration the Advisor
determined that the opinion should be based on four different analyses and
considerations as follows:

         1. Comparison of the benefits received by Censtor from Read-Rite
including cash payments, assumption of liabilities, and most importantly, the
cost avoidance of continuing to develop the technology as compared to the future
potential of executing a "standard" licensing agreement between the parties.

         Under this approach, market share information was compiled on Read-Rite
and used as a basis for determining the anticipated net present value of the
royalty stream should Censtor have executed a traditional license under which a
front end payment would have been made, plus a royalty paid over time. The
result was compared to the benefit received by Censtor.

         Key assumptions were: (i) a license with Read-Rite would have included
a $2.0 million front end payment and a royalty of 1% of sales commencing in
1997; (ii) additional investment of $16.5 million is required to commercialize
the Censtor technology (based on information provided by the Company); (iii) had
the Company suspended operations, it
    

                                       24
<PAGE>   29
   
would have incurred personnel termination liabilities of approximately $500,000;
and (iv) the Company did not provide forecasts beyond the year 2000, royalties
beyond that time were extrapolated based on a standard diffusion curve,

         The results of this analysis indicated that the transaction benefit
received by the Company was $26.4 million, comparing favorably to the $10.45
million net present value estimated should the Company have entered into a
standard licensing agreement with Read-Rite. The calculation for the net present
value of the royalty stream included a 15% risk factor and a 12% capital cost.

         2. Comparison of the transaction with other publicly disclosed
non-exclusive licensing transactions under which ratios were calculated for the
considerations provided to the licensor as a function of anticipated benefits by
the licensee. Licensing transactions identified in this analysis were as
follows:

                  Imatron transaction with Siemens
                  Ethical transaction with Elan
                  Araid transaction with Hoechst
                  Ecogen transaction with Monsanto
                  NPS Pharmaceutical transaction with Amgen
                  ICN Pharmaceutical transaction with Schering Plough

         A ratio was developed for each of the referenced transactions of the
future profit anticipated as a result of the transaction cost. The highest ratio
(the most favorable to the licensee) was the Ethical/Elan transaction with a
ratio of 47.4, with the lowest ratio (most favorable to the licensor) being
Imatron/Siemens transaction at 12.5. The average of the six transactions was
determined to be 28.1. Using the same methodology, the Proposed Transaction was
calculated to be 21.9, well below the average of the licensing transaction
population, and therefore, favorable to the Company, the licensor.

         3. Comparison of the transaction, based on a ratio of the consideration
provided as a function of transaction costs, when compared to other licenses
granted by the Company and a mean ratio of 33 contracts for technology
considerations as a function of transfer cost (the "Ratio") as compiled by
Francis Bibault (Professor , Lyon GSB) in a paper titled "Technology Pricing;
Principles to Strategy".

         Key assumptions included in this analysis were that the Read-Rite
considerations include (i) initial payments and development cost avoidance of
$25.9 million and (ii) the Company's previous licensing transactions included
royalties for a 17 year period and transaction costs of $16.5 million investment
required to commercialize the technology (see estimate previously referenced).

         Using the methodology described in the above cited paper , the Ratio of
the Proposed Transaction was calculated to be 129.5, reflecting $25.9 million
benefit divided by transaction costs estimated to be $200,000. Dr. Bibault's
publication concluded that the mean Ratio for 33 such transactions analyzed was
116.2. Since the Proposed Transaction Ratio exceeds the mean reflected in the
analysis, the Advisor concluded that this approach provided further support to
its fairness of the transaction, from a financial point of view.
    

         The Advisor did not make any independent valuation of the Company's
assets or intellectual property nor did it review any of the Company's corporate
records. In addition, the Advisor assumed, without independent verification, the
accuracy, completeness and fairness of all the financial statements, product
information, marketing strategies and other information regarding the Company
that was provided to the Advisor by the Company and its representatives. The
Company believes the Advisor's lack of independent verification of its
historical financial statements is justified and reasonable under the
circumstances, since the annual financial statements of the Company provided to
the Advisor were audited by Ernst & Young LLP, the Company's independent
auditors. The audited statements covered all but the interim period from July
1995 through March 29, 1996, the date the opinion was issued. Except as
described above, neither the Company nor any affiliate provided instructions to
the Advisor or imposed any limitations on the scope of the Advisor's
investigation.

         Neither the Advisor nor any of its principals or affiliates has or,
over the past two years, has had any material relationship with the Company or
Read-Rite, other than the Advisor's engagement by the Company, described above,
to render an opinion regarding the fairness of the contemplated transaction.
(See "Background" on pages 16-18.)

         For the Advisor's services related to rendering of its written fairness
opinion referred to above in connection with the Proposed Transaction, the
Company has agreed to pay the Advisor a single fee of $35,000. The Company has
agreed to indemnify and hold the Advisor harmless from certain liabilities,
including liabilities under the federal securities laws, and has agreed to
reimburse the Advisor for its reasonable out-of-pocket expenses incurred in
connection with its services, which are estimated to be less than $100.

INTEREST OF MANAGEMENT IN THE TRANSACTION

   
         The Company's management is not affected by this transaction except
that Robert Hempstead, Censtor's Chief Technical Officer, has resigned from
Censtor and was subsequently hired, along with 83 other Censtor employees, by
Read-Rite on February 5, 1996. Dr. Hempstead subsequently resigned from
Read-Rite. It is not contemplated that any other of the Company's management
will become employees of Read-Rite as a result of this transaction.
    

EFFECT ON EMPLOYEES

         As of February 5, 1996, 84 of the 89 employees of the Company became
employees of Read-Rite for the purposes of operating the assets and developing
the technology being transferred to Read-Rite pursuant to the terms of the Asset
Sale Agreement. The remaining four employees (Russell Krapf, Sabine Austin, Mark
Lauer, and Elizabeth Harmon) are continuing to be employed by the Company to
continue the Company's licensing operations. (Garry Garrettson, Censtor's
President has resigned effective April 22, 1996; he will continue to serve on
the Board of Directors if he is elected by the Shareholders.)

APPLICATION OF SALE PROCEEDS

   
         Of the net proceeds from the Proposed Transaction, the Company expects
to use approximately $6.4 million to pay down obligations estimated to be due as
of the Closing, including a $2.0 million escrow for the July 31, 1996 Denka
payment and $1,000,000 plus interest, will be used to pay obligations to certain
Shareholders of which $546,675, plus accrued interest is due at the Closing. 
The following two tables detail the application of anticipated proceeds 
related to the Proposed Transaction and the Shareholders whose notes will be 
repaid from the proceeds of the sale. The remainder of the proceeds, if
any, will be used for general working capital purposes with respect to its
remaining business operations. The Company has no present intent to pay a
dividend to Shareholders or to otherwise distribute to its Shareholders any
proceeds received from the Proposed Transaction.

         The use of net proceeds is estimated as follows:

CERTAIN FEDERAL INCOME TAX CONSEQUENCES

   
         For tax purposes, the Company will recognize income or gain as a result
of the Proposed Transaction. Notwithstanding, the Company determined that it
will not have to pay any income tax related to the Proposed Transaction because
of any income or gain will be offset by current year net operating loss or prior
year net operating loss carry forwards.

         Additionally, the Company determined that the Proposed Transaction will
not have any federal income tax consequences to the Shareholders.
    

RECOMMENDATION OF THE BOARD OF DIRECTORS

         The Company's Board retained the Advisor to provide an opinion to the
Board of Directors regarding the fairness, from a financial point of view, of
the Asset Sale Agreement. The Advisor provides financial advisory services
associated with mergers, acquisitions and strategic partnering for emerging
growth companies. Since the Advisor was founded in 1990, it has completed over
50 such assignments. The Advisor is located in Palo Alto, California. In
addition, the Company's Board of Directors unanimously determined that the terms
of the Proposed Transaction are fair and in the best interest of the Company and
its Shareholders and recommends a vote in favor of the Proposed Transaction. In
the course of reaching its decision to approve the Proposed Transaction, the
Board consulted with its legal and financial advisors as well as the Company's
management and considered the following factors:

   
         (1) The Board's desire to focus the Company's resources on developing
             its proprietary technology through patents and licensing of its
             proprietary technology where it believes that the Company has
             greater asset value, competitive advantage and probability of
             success. The Board has determined that the risk and cost of raising
             the necessary capital to pursue the manufacture of magnetic heads
             using the Company's technology is prohibitive. The Board has
             therefore adopted a strategy of capitalizing on its proprietary
             technology through further patent protection of its existing
             technology and licensing of that protected technology.

         (2) The anticipated positive effects upon the Company's balance sheet
             and results of operations from the use of the net proceeds
             therefrom to retire indebtedness and expand the Company's licensing
             capabilities. Among other factors considered by the Board of
             Directors were the positive effects of using $6.4 million of the
             anticipated proceeds from the Proposed Transaction, which based on
             the agreement entered into with the debt holder will eliminate
             substantially all of the Company's short and long-term debt,
             currently approximately $18.0 million, (comprised approximately of
             Denka ($14.3 million), Silicon Valley Bank ($1.0 million),
             Shareholder loan ($1.0 million), equipment leasing contracts
             ($0.9 million), and trade payables ($0.8 million)), which would
             result in annual interest savings of

    

                                       27
<PAGE>   32
   
             approximately $1.2 million. In addition, the Proposed Transaction
             would allow the Company to eliminate a rapidly deteriorating asset
             and earnings base, substitute the Company's relatively illiquid
             assets for cash, and recraft its infrastructure to create a more
             efficient business with lower ongoing costs and at the same time no
             loss of jobs. The Board felt that this model would have a better
             prospect of increasing Shareholder value because the Company, with
             limited resources, would be directly focused on two objectives: (1)
             increasing the patent portfolio of intellectual property, the
             Company's most valuable asset and (2) licensing the intellectual
             property to create a royalty stream.

         (3) The absence of any serious offers from any other third parties
             regarding a possible acquisition of the Company's assets or a
             possible merger with the Company. The Board had been involved in
             ongoing discussions with management regarding the prospects of
             raising equity financing, debt financing, merger and acquisition;
             additionally, the Board had been in discussions with potential
             equity investors such as Allen Patricof, US Venture Partners,
             Pacven Walden Management, Integral Capital Partners, Burr Egan,
             Deleage, Paine Webber, JAFCO (Japan) and others. Management and the
             Board tried unsuccessfully for seven months to raise additional
             capital for the Company. The Board concluded that there were no
             offers other than Read-Rite forthcoming.

         (4) The opinion of the Advisor, that the purchase price is fair, from a
             financial point of view, to the Company and its Shareholders. The
             Advisor reviewed its opinion in detail with the Board of Directors
             and asked questions with respect to the various methodologies used,
             the details of other licensing agreements used, the background and
             experience base of the Advisor as well as other questions regarding
             the analysis performed by the Advisor.

         (5) The willingness of Read-Rite to continue to employ the Company's
             work force. The Board discussed the potential liability of laying
             off the employees that were employed by Read-Rite. The Board felt
             that the Shareholders were better served by avoiding the
             termination expenses involved and utilizing the funds instead to
             perfect the intellectual property and finding additional licensees
             of the Company's technology.

         Considering all of the above factors, the Board of Directors concluded
that the Company should become tightly focused on licensing its proprietary
technology and that it is likely that in an increasingly competitive environment
the physical assets to be sold and the technology to be licensed would not have
a value higher than that which existed at the time that the Proposed Transaction
was approved by the Company's Board. In addition, management, with its intimate
knowledge of the physical assets to be sold and the technology to be licensed
(on a non-exclusive basis) and with the assistance and advice of the Advisor,
had concluded that it was unlikely that any purchaser other than Read-Rite would
be willing to pay a price higher than that to be received in the Proposed
Transaction and communicated this to the Board of Directors. The Board did not
independently establish a value for the Proposed Transaction, but based on all
the above factors determined that the Proposed Transaction was fair and
reasonable to the Company and its Shareholders. The Board did not assign a
weight for the individual factors considered in evaluating the Proposed
Transaction. See "Proposal Three: The Proposed Transaction - Background" (pages
18-23), above.

                              AVAILABLE INFORMATION

         The Company is subject to the information requirements of the

against the portion of the Purchase Price to be paid to Seller on the Closing
Date any Loan Adjustment Amount (as defined in Section 3.3 hereof) and all
Seller Expenses (as defined in Section 3.4 hereof).

            3.3 Initial Loan to Seller. In connection with that certain Letter
of Intent between Seller and Buyer dated February 2, 1996 (the "Letter

certain Promissory Notes dated February 2, 1996, February 29, 1996 and March 22,
1996 (collectively, the "Promissory Notes"). The amount of principal, interest
and other amounts outstanding from time to time under the Promissory Notes is
hereafter referred to as the "Loan Amount." Seller agrees that all amounts
loaned to it by Buyer pursuant to the Promissory Notes have been used and will
be used by Seller as operating funds in the normal and ordinary course of
business. The "Loan Adjustment Amount" shall equal (i) fifty percent (50%) of
the Loan Amount outstanding on the date hereof plus (ii) fifty percent (50%) of
the Compensation accrued or paid by Buyer with respect to the Employees through

1996) plus (iii) fifty percent (50%) of all accrued but unpaid expenses of
Seller for the period beginning on February 2, 1996 through the date hereof less
(iv) all prepaid expenses of Seller outstanding on the date hereof to the extent
Seller can demonstrate that such expenses were paid from amounts borrowed from
Buyer pursuant to the Promissory Notes. The determination of any accrued amounts
or prepaid expenses shall be made in accordance with generally accepted
accounting principles consistently applied, and shall be subject to the mutual
review and agreement of Seller and Buyer. Buyer hereby agrees with Seller that
any Loan Amount outstanding as of the Closing Date less the Loan Adjustment
Amount shall be forgiven as of the Closing Date and shall constitute additional
consideration paid by Buyer to Seller hereunder. The Loan Adjustment Amount
shall be 


                                      -5-
<PAGE>   42
computed by Buyer, and Buyer shall deliver a copy of such computation to Seller
on or prior to the Closing Date.

            3.4 Additional Loan to Seller. Upon the execution and delivery of
this Agreement, Buyer shall agree to loan Seller up to an additional $800,000,
such loan to be evidenced by a promissory note in the form attached hereto as
Exhibit B (the "Bridge Note"). Buyer acknowledges that the proceeds of any loans
obtained by Seller from Buyer pursuant to the Bridge Note may be used to fund
ongoing costs incurred by Seller in the usual and ordinary course of its
business, including without limitation Seller's accounting, legal and other
costs related to the transactions contemplated hereby and costs associated with
the Assumed Contracts. For purposes hereof, Seller and Buyer agree that any
expenses of Seller related to the period subsequent to the date hereof which are
paid or accrued but unpaid pursuant to the terms of the Assumed Contracts,
including any lease payments, property taxes, insurance, utilities or
maintenance charges (whether incurred to preserve the Facility of Seller
referenced in the Lease Agreement, any Asset being leased pursuant to those
Equipment Lease Agreements which constitute Assumed Contracts, or any of the
other Assets) are referred to herein as "Nonseller Expenses." All other expenses
of any kind whatsoever paid or accrued by Seller, including without limitation
legal and accounting fees, patent filing and maintenance fees, salaries and
benefits, workers' compensation expenses, any accrued interest under the Bridge
Note and any amounts owed by Seller to Buyer under the Bridge Note which were
not used by Seller to pay Nonseller Expenses are referred to herein as "Seller
Expenses." At the Closing, Buyer shall be entitled to credit against the amount
of the Purchase Price to be paid by Buyer to Seller the full amount of any
Seller Expenses, and any other amount due under the Bridge Note shall be
forgiven by Buyer and shall constitute additional consideration paid by Buyer to
Seller hereunder. The determination of any accrued amounts hereunder shall be
made in accordance with generally accepted accounting principles consistently
applied, and shall be subject to the mutual review and agreement of Seller and
Buyer.

            3.5 Assumed Liabilities. On the Closing Date, Buyer shall assume and
agree thereafter to pay, perform and discharge only Seller's obligations under
the Lease Agreement and the Equipment Lease Agreements to which Seller is a
party and which are specifically listed on Schedule 3.5 hereto (collectively,
the "Assumed Contracts") and no others, but only to the extent they remain
unpaid and unperformed on the Closing Date and excluding any such obligations or
liabilities based on any actions by Seller or any failure by Seller to perform
its obligations under the Assumed Contracts prior to the Closing Date (the
"Assumed Liabilities"). Except for the Assumed Liabilities and as contemplated
by Section 8.6 hereof, Buyer shall not assume, directly or indirectly, or have
any responsibility for any Liability of Seller, and Seller shall retain all
Liabilities arising from the operation of the Assets and the related business
prior to the Closing Date, other than the Assumed Liabilities. Without limiting
the foregoing, Buyer shall not directly or indirectly, assume or have any 
responsibility for any liability for any Compensation or other Liabilities 
related to the employment of the Employees by the Seller prior to February 5, 
1996.

            3.6 Tax Allocation. The parties agree to allocate the purchase price
for the Assets in accordance with a schedule that Buyer shall prepare and
deliver to Seller at the Closing (the "Allocation Schedule"). The Allocation
Schedule shall be subject to Seller's approval, which shall not 


                                      -6-
<PAGE>   43
be withheld unreasonably. Buyer and Seller agree that they will prepare and file
their federal and any state or local income tax returns based on the purchase
price allocation contained in the Allocation Schedule and agree not to take a
reporting position inconsistent therewith. This allocation is intended to comply
with Section 1060 of the Internal Revenue Code of 1986, as amended (the "Code"),
and Buyer and Seller hereby agree to prepare and file all notices or other
filings required pursuant to such section and hereby further agree that all such
notices or filings will be based on the allocation contained in the Allocation

the Disclosure Schedule attached hereto as Exhibit E, which schedule shall
specifically reference the Sections of this Agreement to which the disclosure
therein applies, Seller represents and warrants to Buyer as of the date of this
Agreement and as of the Closing Date as follows:

                (a) Organization, Standing and Qualification. Seller is a

of California. Seller has all requisite corporate power and authority and is
entitled to carry on its business as it is now being conducted, and to own,
lease or operate the properties owned, leased and operated by it in the places
where such business is now conducted and where the Assets and its other
properties are now owned, leased or operated. Seller is qualified to do business
as a foreign corporation in all jurisdictions where such qualification is
required for the conduct of its business, except where the failure to be so
qualified would not have a material adverse effect on Seller or the Assets.

                (b) Execution, Delivery and Performance. Neither the execution
and delivery nor the performance of this Agreement by Seller will, with or
without the giving of notice or the passage of time, or both, conflict with,
result in a default, right to accelerate or loss of rights under, or result in
the creation of any lien, charge or encumbrance pursuant to any provisions of
Seller's Articles of Incorporation or Bylaws, or any franchise, mortgage, deed
of trust, lease, license, agreement (including each of the Assumed Contracts) or
understanding, or conflict with, result in a default, right to accelerate or
loss of rights under, or result in the creation of any lien, charge or
encumbrance pursuant to any law, ordinance, rule or regulation, or any order,

provide Buyer with such assistance as may be required in connection with the

providing such assistance and (b) retain and provide Buyer with all records or
other information that may be relevant to the preparation of any Returns, or the
conduct of any audit or examination, or other Tax proceeding by a Governmental
Body or otherwise. Seller shall retain all relevant documents, including prior
year's Returns, supporting work schedules and other records or information that
may be relevant to such returns and shall not destroy or otherwise dispose of
any such records without the prior written consent of Buyer.

                (e) Claims and Litigation. No Claim (including warranty claims),
legal action, suit, arbitration, governmental investigation or other legal,
regulatory or administrative proceeding is pending against Seller related to the
Assets, nor to the best of Seller's knowledge is there any threat thereof

Agreement, and to the best of Seller's knowledge there is no basis for any such
Claim, suit or other proceeding.

any Hazardous Substance at the Facility, or the air, soil, groundwater or
surface water thereof, in violation of Environmental Law.

                    (iii) The Disclosure Schedule accurately describes all of
the Environmental Permits currently held by the Seller and such Environmental
Permits are all of the Environmental Permits necessary for the continued conduct
of any Hazardous Substance Activity of the Seller as such activities are

conditions of any Environmental Permit which is or has been in force with
respect to its Hazardous Substances Activities. No circumstances exist which
could cause any Environmental Permit to be revoked, modified, or rendered
non-renewable upon payment of the permit fee or which could impose upon Seller
the obligation to obtain any additional Environmental Permit. All Environmental
Permits and all other consents and clearances required by any Environmental Law
or any agreement to which Seller is bound as a condition to the performance and
enforcement of this Agreement, including without limitation, all environmental
clearances or "closure" obligations required by any Governmental Body have been

<PAGE>   48
                    (iv) In the best of Seller's knowledge, there is no fact or
circumstance which presently or with the passing of time could involve the
Facility in any proceeding concerning an Environmental Liability or impose upon
the Facility or Buyer any Environmental Liability.

                    (v)  Seller has delivered to Buyer all records concerning 
its Hazardous Substance Activities and all environmental audits and
environmental assessments of the Facility conducted at the request of, or

the Closing Date, none of the Assets shall be disposed of. All tangible personal
property, including machinery, equipment and fixtures, included in the Assets
is, and at the Closing Date will be, in good operating condition and repair,
ordinary wear and tear and routine maintenance excepted. The present use of

affecting Seller or its business concerning any Employee. Seller has no
Liabilities to any Employee or beneficiary of an Employee.

supplement the Proxy Statement.

                (n) Vote Required. The affirmative votes of the holders of a
majority of the shares of Seller's Common Stock and Preferred Stock outstanding

the transactions contemplated hereby.

                (o) Board Approval. The Board of Directors of Seller has
unanimously (i) approved this Agreement and the transactions contemplated

certificate furnished pursuant to this Agreement, contains or will contain any
untrue statement of a material fact at the Closing Date, or omits or will omit

                                      -14-
<PAGE>   51
            6.3 Discharge of Liabilities. From and after the date hereof, Seller
shall discharge when due all Liabilities of Seller, provided that upon the
Closing, Buyer shall be responsible for all Assumed Liabilities.

            6.4 Access to Information. Between the date of this Agreement and
the Closing Date, Seller shall give Buyer and its authorized representatives
reasonable access during normal working hours to Seller's facilities and
properties, and its books and records, shall permit Buyer to make inspections

as Buyer may from time to time reasonably request.

            6.5 Hiring of Employees. Seller acknowledges and agrees that with
Seller's consent, each of the Employees became employed by Buyer on February 5,
1996. Seller further acknowledges and agrees that the Employees were hired by
Buyer at Seller's request. In Seller, on behalf of itself, its shareholders,
officers and directors and anyone claiming by or through Seller, hereby releases
and forever discharges Seller and all of its subsidiaries, officers, directors,
employees, agents and anyone acting by or through Buyer from any and all Claims,
demands, torts, causes or action or claims for relief of whatever kind or
nature, whether known or unknown, which Seller may have or which may hereafter
be asserted or accrue against the Release Parties, or any of them, resulting
from or in any way relating to Buyer's hiring of the Employees.

            6.6 No Other Negotiations. From and after the date of this Agreement
until the earlier of the Closing Date or the termination of this Agreement in
accordance with its terms, Seller shall not, directly or indirectly (i) solicit,
initiate discussion or engage in negotiations with any person (whether such
negotiations are initiated by Seller or otherwise) or take any other action
intended or designed to facilitate the efforts of any person, other than Buyer,
relating to the possible acquisition of Seller or any of its subsidiaries
(whether by way of merger, purchase of capital stock, purchase of assets or
otherwise) or any of its or their capital stock or any material portion of its
or their assets (with any such efforts by any such person, including a firm
proposal to make such an acquisition, to be referred to as an "Acquisition
Proposal"), (ii) provide non-public information with respect to Seller or any of
its subsidiaries to any person, other than Buyer, relating to a possible
Acquisition Proposal by any person, other than Buyer, (iii) enter into an
agreement with any person, other than Buyer, providing for a possible
Acquisition Proposal, or (iv) make or authorize any statement, recommen dation
or solicitation in support of any possible Acquisition Proposal by any person
other than Buyer. If Seller or any of its subsidiaries receives any unsolicited
offer or proposal to enter negotiations relating to an Acquisition Proposal,
Seller shall immediately notify Buyer thereof, including infor mation as to the
identity of the party making any such offer or proposal and the specific terms
of such offer or proposal, as the case may be. Seller recognizes and
acknowledges that a breach of this Section 6.6 may cause irreparable and
material loss and damage to Buyer as to which Buyer may not have an adequate
remedy at law or in damages and that, accordingly, Seller agrees that the
issuance of an injunction or other equitable remedy is the appropriate remedy
for any such breach. Notwith standing the foregoing, in the event that Seller
receives a bona fide, unsolicited proposal relating to an Acquisition Proposal
by any person other than Buyer, which proposal, in the reasonable good faith
judgment of Seller's Board of Directors, is financially more favorable to the
shareholders of Seller than the terms of this Agreement (a "Superior Proposal"),
Seller's Board of Directors may engage in 

                                      -15-
<PAGE>   52
discussions or negotiations with (but not soliciting or initiating such
discussions or negotiations or encouraging inquiries or the making of an
Acquisition Proposal by any third party other than the party making the Superior
Proposal) the party making the Superior Proposal if Seller's Board of Directors
determines in good faith, based on the written advice of outside legal counsel,
that such action is required by reason of the fiduciary duties of the members of
Seller's Board of Directors to Seller's shareholders under applicable law;
provided that in such event Seller notifies Buyer of such determination by the
Seller's Board of Directors and provides Buyer with a true and complete copy of
the Superior Proposal received from such third party, if the Superior Proposal
is in writing, or a complete written summary thereof, if it is not in writing,
and provides Buyer with all documents containing or referring to non-public
information of Seller that are supplied to such third party.

            6.7 Proxy Statement. As promptly as practicable after the execution
of this Agreement, Seller shall prepare, and file with the Securities and
Exchange Commission, preliminary proxy materials relating to the approval of the
transactions contemplated hereby by the shareholders of Seller. The Proxy
Statement shall include the recommendation of the Board of Directors of Seller
in favor of the transactions contemplated hereby.

            6.8 Meetings of Shareholders. Seller shall promptly after the date
hereof take all action necessary in accordance with law and its Articles of
Incorporation and Bylaws to convene the Shareholders Meeting on or prior to
April 5, 1996 or as soon thereafter as is practicable. Seller shall use its best
efforts to solicit from its shareholders proxies in favor of the transactions
contemplated thereby and shall take all other action necessary or advisable to
secure the vote or consent of shareholders required to effect the transactions
contemplated thereby.

            6.9 Public Disclosure. Seller and Buyer shall consult with each
other before issuing any press release or otherwise making any public statement
or making any other public (or non-confidential) disclosure regarding the terms
of this Agreement and the transactions contemplated hereby, and neither shall
issue any such press release or make any such statement or disclosure without
the prior approval of the other (which approval shall not be unreasonably
withheld), except as may be required by law.

            6.10 Consents. Promptly after the date hereof, Seller and Buyer
shall consult with each other regarding the actions which are required to be
taken to cause the Assumed Contracts to be transferred to Buyer on the Closing
Date. Subject to such consultations, Seller shall promptly apply for or
otherwise seek, and use its best efforts to obtain, all consents and approvals
required to be obtained by it for the consummation of the transactions
contemplated hereby and shall use its best efforts to obtain all necessary
consents, waivers and approvals under any of the Assumed Contracts in connection
with the transaction for the assignment thereof or otherwise.

            6.11 Voting Agreements. Prior to or concurrently with the execution
of this Agreement, each of Seller's shareholders named in Schedule 6.11 hereto
shall have executed and delivered to Buyer a Voting Agreement substantially in
the form of Exhibit F attached hereto.

            6.12 Buyer Subsidiary as Party. Seller acknowledges that Buyer may
create or use a subsidiary corporation that is wholly-owned directly or
indirectly by Buyer (a "Buyer Subsidiary") to own and operate the Assets after
the Closing Date. To the extent Buyer determines to create the Buyer Subsidiary
prior to the Closing Date, Seller agrees that the Buyer Subsidiary shall be
substi tuted for Buyer for the purpose of exercising those rights and performing
those obligations of Buyer as Buyer shall designate. Following the Closing Date
and the transfer of the Assets to the Buyer Subsidiary, the Buyer Subsidiary
shall be substituted for Buyer for the purpose of such sections. The creation or
use by Buyer of the Buyer Subsidiary pursuant to this Section 6.12, shall not
serve to (i) excuse Buyer as a primary obligor with respect to any obligation
delegated to the Buyer Subsidiary; or (ii) limit in any manner the right of
Buyer to directly enforce any rights hereunder that Buyer may have delegated to
the Buyer Subsidiary.

            6.13 Release of Liens. On or prior to the Closing Date, all Liens on
the Assets and Seller's intellectual property, including but not limited to, (i)
those in favor of Silicon Valley Bank, (ii) those in favor of the investors
listed or described on the Disclosure Schedule and (iii) those otherwise listed
or referred to in the Disclosure Schedule; shall have been released or all such
actions as may be required in the sole judgment of Buyer to cause the release of
such Liens shall have been taken.

            6.14 Release of Denka Liens. On or prior to the Closing Date, Seller
shall have deposited in escrow with its legal counsel, all amounts as are
required to satisfy any obligations of Seller to Denka necessary to obtain a
release of all Liens on the Assets and Seller's intellectual property in favor
of Denka, all as further detailed in Section 2.3.3 of the License Agreement.
Seller further covenants and agrees with Buyer that Seller will take all such
further actions as may be required in the sole judgment of Buyer to cause all
Liens in favor of Denka to be released on or prior to July 31, 1996.


                                    SECTION 7

temporary restraining order), decree or ruling or taken any other action
restraining, enjoining or otherwise prohibiting the transactions contemplated
hereby and such order, decree, ruling or other action shall have become final

Section 7.2 hereof, at Buyer's election, Buyer and Seller shall enter into a
Limited License Agreement in substantially the form attached hereto as Exhibit
G (the "Limited License Agreement") and Buyer shall have the right to continue
to employ all of the Employees. In connection with the payment to be made by
Buyer to Seller pursuant to the Limited License Agreement, the amount of such
payment shall be reduced by the full amount of the Loan Adjustment Amount (as
defined in Section 3.3 hereof).

                (b) If this Agreement is terminated pursuant to Section 7.3
hereof or in connection with a Superior Proposal (as defined in Section 6.6
hereof), at Buyer's election, Buyer shall have the right to continue to employee
all of the Employees and Buyer and Seller shall enter into the Limited License
Agreement. In such event, Buyer shall not be obligated to make any payment to
Seller under the Limited License Agreement. In addition, Seller shall be
obligated to repay all amounts which Seller has borrowed from Buyer pursuant to
the Promissory Notes, the Bridge Note or otherwise.

                (c) If this Agreement is terminated pursuant to Section 7.4
hereof, Buyer agrees that any and all amounts due and payable by Seller to Buyer
pursuant to the Promissory Notes, the Bridge Note or otherwise shall be
discharged and canceled. In such event, Buyer shall have the right to continue
to employ all of the Employees and, at Buyer's election, Buyer and Seller shall
enter into the Limited License Agreement.


                                    SECTION 8

         8. HOLDBACK OF FINAL PAYMENT; INDEMNIFICATION

            8.1 Holdback of Final Payment. The payments referenced in Section
3.1(ii) and (iii) above (the "Interim Payments") and the Final Payment shall be
retained by Buyer as security to compensate Buyer for any loss, expense,
liability or other damage, including attorneys' fees, to the extent of the
amount of such loss, expense, liability or other damage (collectively "Damages")
that Buyer has incurred or reasonably anticipates incurring by reason of the
breach by Seller of any representation, warranty, covenant or agreement of, or
misrepresentation by, Seller contained in this Agreement or in the License
Agreement. In the case of a third party claim, any indemnification for Damages
hereunder shall be offset or reduced by any amount actually recovered by Buyer
pursuant to counterclaims made by it directly relating to the facts giving rise
to such third party claims. Nothing in this Agreement shall limit the liability
(i) of Seller for any breach of any representation, warranty or 


                                      -18-
<PAGE>   55
covenant if the Closing does not occur, or (ii) of any shareholder of Seller in
connection with any breach by such shareholder of the Voting Agreement signed by
such shareholder in connection with this Agreement.

            8.2 Claims upon Final Payment.

                (a) Subject to the other provisions of this Section 8, the
Interim Payments and the Final Payment shall be paid by Buyer to Seller on the
respective payment dates set forth in Section 3.1; provided, however, that Buyer
shall have no obligation to pay to Seller such portion of such payments which,
in the reasonable judgment of Buyer, subject to the objection of the Seller and
the subsequent arbitration of the matter in the manner provided below, is
necessary to satisfy any unsatisfied claims specified in any Officer's
Certificate theretofore delivered to the Seller on or prior to the relevant
payment date until such claims have been resolved. As soon as all such claims
have been resolved, the Buyer shall deliver to Seller the remaining portion of
the applicable payment not required to satisfy such claims.

                (b) Upon receipt by the Seller on or before the applicable
payment date of a certificate signed by any officer of Buyer (an "Officer's
Certificate"):

                    (i)  stating that Damages exist or are reasonably 
anticipated to exist and specifying in reasonable detail the individual items as
to which Damages relate, the date each such item was paid, or properly accrued
or arose, and the nature of the misrepresentation, breach of warranty or claim
to which such item is related, then

                    (ii) the applicable payment shall be reduced dollar for
dollar in an amount equal to such Damages.

                (c) The Officer's Certificate shall be delivered within a
reasonable time after Buyer concludes that it has a claim for Damages for which
it will seek recovery and concerning which it has the information required to be
stated in the Officer's Certificate.

            8.3 Objections to Claims. Upon the expiration of a thirty (30) day
period following delivery of the Officer's Certificate by Buyer to Seller, the
amount of the applicable payment shall be deemed to be reduced by the amount of
the Damages unless Seller shall object in a written statement delivered to the
Buyer prior to the expiration of such thirty (30) day period. Notwithstanding
anything herein to the contrary, Seller shall not be liable for any claims for
Damages unless the aggregate amount of such Damages exceeds $50,000.00 or unless
the amount of any individual claim for Damages exceeds $25,000.00, provided that
in either such case Buyer shall be entitled to recover for its entire claim once
either such threshold is met. Except as set forth in Section 4.2 of this
Agreement, the holdback provisions contained in this Section 8 shall be deemed
to be the exclusive remedy of Buyer in the event of any breach by Seller of any
representation or warranty contained herein (or in any certificates or documents
delivered pursuant hereto), except for (i) claims relating to fraud or willful
concealment or willful misrepresentation by Seller, (ii) any claim 


                                      -19-
<PAGE>   56
or action by Buyer under the License Agreement and (iii) any claim or action by
Buyer related to Seller's obligations under Section 6.16 hereof.

            8.4 Resolution of Conflicts, Arbitration.

                (i)   In case the Seller shall so object in writing to any claim
or claims by Buyer made in any Officer's Certificate, Buyer shall have thirty
(30) days to respond in a written statement to the objection of the Seller. If
after such thirty (30) day period there remains a dispute as to any claims, the
Seller and Buyer shall attempt in good faith for thirty (30) days to agree upon
the rights of the respective parties with respect to each of such claims. If the
Seller and Buyer should so agree, a memorandum setting forth such agreement
shall be prepared and signed by both parties.

                (ii)  If no such agreement can be reached after good faith
negotiation, either Buyer or the Seller may, by written notice to the other,
demand arbitration of the matter unless the amount of the damage or loss is at
issue in pending litigation with a third party, in which event arbitration shall
not be commenced until such amount is ascertained or both parties agree to
arbitration; and in either such event the matter shall be settled by arbitration
conducted by three (3) arbitrators. Within fifteen (15) days after such written
notice is sent, Buyer and the Seller shall each select one (1) arbitrator, and
the two (2) arbitrators so selected shall select a third arbitrator. The
decision of the arbitrators as to the validity and amount of any claim in such
Officer's Certificate shall be binding and conclusive upon the parties to this
Agreement.

                (iii) Judgment upon any award rendered by the arbitrators may be
entered in any court having jurisdiction. Any such arbitration shall be held in
Santa Clara, California under the commercial rules then in effect of the
American Arbitration Association. For purposes of this Section 8.4, in any
arbitration hereunder in which any claim or the amount thereof stated in the
Officer's Certificate is at issue, Buyer shall be deemed to be the
Non-Prevailing Party unless the arbitrators award Buyer more than one-half (1/2)
of the amount in dispute, plus any amounts not in dispute; in that event, Seller
shall be deemed to be the Non-Prevailing Party. The Non-Prevailing Party to an
arbitration shall pay its own expenses, the fees of each arbitrator, the
administrative fee of the American Arbitration Association, and the expenses,
including without limitation, attorneys' fees and costs, reasonably incurred by
the other party to the arbitration.

            8.5 Third-Party Claims. In the event Buyer becomes aware of a
third-party claim which Buyer believes may result in a claim against the Final
Payment, Buyer shall notify the Seller of such claim, and the Seller shall be
entitled, its expense, to participate in any defense of such claim. Buyer may
not effect the settlement of any such claim without the consent of the Seller,
which consent shall not be unreasonably withheld. In the event that the Seller
has consented to any such settlement, the Seller shall have no power or
authority to object under any provision of this Section 8 to the amount of any
claim by Buyer against the Interim Payments or the Final Payment for indemnity
with respect to such settlement.

            8.6 Conduct of the Business of the Assets. Seller acknowledges and
agrees that at Seller's request and with Seller's informed consent, Buyer has
agreed to operate the Assets in place at 

                                      -20-
<PAGE>   57
the Facility from February 5, 1996 until the Closing Date. Accordingly, Seller
and Buyer hereby agree that Buyer shall not be entitled to recover for any
Damages resulting from the actions of Buyer or any employee of Buyer to the
extent that any such action results in the breach by Seller of any
representation, warranty, covenant or agreement of Seller contained in this
Agreement nor shall such actions by Buyer constitute a breach by Seller of any
covenant or agreement hereunder or of any representation or warranty of Seller
hereunder.


                                    SECTION 9

         9. MISCELLANEOUS.

            9.1 Absence of Third Party Beneficiary Rights. No provisions of this

other person or entity unless specifically provided otherwise herein, and,
except as so provided, all provisions hereof will be personal solely between the
parties to this Agreement.

            9.2 Further Assurances. Each party agrees to cooperate fully with
the other party and to execute such further instruments, documents and
agreements and to give such further written assurances and to make physical

Buyer from and after the date hereof as may be reasonably requested to evidence

            9.3 Changes, Waivers, Etc. Neither this Agreement nor any provision
hereof may be amended, changed, waived, discharged or terminated orally, except

March 29, 1996

Board of Directors
Censtor Corporation
530 Race Street
San Jose, CA  95126

Gentlemen:

You have requested our opinion as to the fairness, from a financial point of
view, to the shareholders of Censtor Corporation ("Censtor") of the
consideration to be paid by Read-Rite Corporation ("RRC") in the transactions
between Censtor and RRC as set forth in the Agreement for Purchase and Sale of
Assets dated March 29, 1996 and License Agreements attached as exhibits thereto
(the "Agreements").

Von Gehr International, as part of its investment banking business, is regularly
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions and corporate partnering transactions.

In arriving at our opinion, we have reviewed the Agreements and also have
reviewed financial, product and other information that was furnished to us by
Censtor. We also have held discussions with members of the senior managements of
Censtor and RRC regarding the historic and current business operations and
future risks and prospects of their respective companies including their
expectations for certain strategic benefits of the transaction. We reviewed the
basic structure of the technology licenses previously granted by Censtor, and in
addition, have analyzed consideration provided in certain other similar
licensing transactions, and conducted such other financial studies, analyses and
investigations as we deemed appropriate for purposes of this opinion.

We have assumed, without independent verification, the accuracy, completeness
and fairness of all of the financial statements, product information, marketing
strategies and other information regarding Censtor which have been provided to
us by the Company and its representatives. We did not make any independent
evaluation of Censtor's assets or technologies, nor did we independently review
any of their corporate records.
<PAGE>   62
Censtor Corporation                                                       Page 2
Board of Directors                                                March 29, 1996


Based on the foregoing and such other factors as we deem relevant, we are of the
opinion as of the date hereof, that the payment of $9,025,000 plus additional
considerations including forgiveness of approximately 50% of the $800,000 loan
provided by RRC to Censtor and assumption of the outstanding lease obligations
of approximately $1,300,000 in exchange for all of the "hard" assets (machinery,
equipment, etc.) of the Company (subject to non material defined exclusions) and
a fully paid up non exclusive license to Censtor's intellectual property, as set
forth in the Agreements, is fair, from a financial point of view, to Censtor
shareholders.

Sincerely Yours,


/s/ VON GEHR INTERNATIONAL

                  UNAUDITED PRO FORMA CONDENSED FINANCIAL DATA

         The following unaudited pro forma condensed balance sheet at March 31,
1996, and unaudited pro forma condensed statements of operations for the year
ended June 30, 1995 and the nine months ended March 31, 1996 give pro forma
effect to the estimated financial effects of the Asset Sale Agreement (the
"Agreement") with Read-Rite. The pro forma condensed balance sheet as of March
31, 1996 gives pro forma effect to the Agreement as if such transactions were
consummated on that date. The pro forma condensed statements of operations for
the year ended June 30, 1995 and the nine months ended March 31, 1996, present
the results of operations of Censtor as if the Agreement occurred on July 1,
1994. The pro forma information is based on the historical financial statements
of Censtor giving effect to the assumptions and adjustments set forth in the
accompanying notes.

         The unaudited pro forma condensed financial data have been prepared by
Censtor management and are not necessarily indicative of how the Company's
balance sheet and results of operations would have been presented had the
transaction with Read-Rite actually been consummated at the assumed dates, nor
are they necessarily indicative of the presentation of the Company's balance
sheet and results of operations for any future period. The unaudited pro forma
condensed financial data should be read in conjunction with the financial
statements and related notes thereto and Management's Discussion and Analysis of
Financial Condition and Results of Operations incorporated herein by reference.

NOTES TO UNAUDITED PRO-FORMA CONDENSED FINANCIAL DATA

(A)  Prior to the consummation of the Agreement, the Company was primarily
     engaged in research and development activities and providing technological
     assistance and support to its licensees. In conjunction with the Agreement,
     substantially all of the Company's employees, including all of its research
     and development employees, were transferred to Read-Rite. Accordingly,
     research and development expenses and a significant portion of selling,
     general and administrative expenses would not have been incurred. Without a
     research and development department to provide ongoing technological
     assistance and support to its licensees, the non-refundable license fees
     (and any related withholding tax) would have been recognized when the
     license fees were received.

(B)  No interest income is reflected on the cash transferred to the Company by
     Read-Rite.

(C)  The Company expects a reduction in interest expense following the
     assumption of the capital leases by Read-Rite as part of the Agreement and
     due to the use of $2,000,000 of the sale proceeds to repay a portion of the
     subordinated debentures.

(D)  Reflects the transfer of the majority of the Company's tangible fixed
     assets to Read-Rite and the assumption by Read-Rite of the associated
     capital leases in accordance with the agreement. A gain of $698,274 arises
     on the sale of the equipment and transfer of the assembled workforce.

(E)  The Company will receive gross consideration of $9,025,000 in connection
     with the Agreement. The gross consideration will be reduced by
     approximately $1,600,000 of the $2,450,000 total expected to be outstanding
     at the Closing with respect to an existing note payable of $900,000 to
     Read-Rite and an additional $1,550,000 bridge loan from Read-Rite received
     or to be received under terms of the Agreement. The remaining amounts
     received under the notes, (about $850,000), will be used to pay certain
     expenses incurred up to the Closing relating to the employees transferred
     and the physical assets to be sold to Read-Rite and these amounts will be
     forgiven. The Company estimates that it will receive net consideration of
     $8,125,000 of which $5,625,000 will be received at the Closing. The net
     consideration will be used as follows:

                                                       $2,500,000

     Further, following the assumption by Read-Rite of the capital leases, the
     restrictions over $94,450 of the Company's cash will be released.

(F)  Deferred revenue relates to the license fee received or due from Read-Rite.
     Under the terms of the Agreement, Censtor shall continue to file patent
     applications and maintain and defend the patents during the term of the
     Agreement.

     Censtor has granted Read-Rite a security interest in its intellectual
     property to secure certain obligations and warranties with respect to the
     intellectual property for a period of six years following the effective
     date of the Agreement. After the third year after the effective date of the
     Agreement, Censtor may terminate the security interest by depositing $4.0
     million in an escrow account. Such amount is reduced by $1.0 million in
     each of the succeeding two years, and the escrow terminates the following
     year.

     Management believes that all of the license fee may not be realized due to
     amounts which will have to be paid out of the escrow fund or amounts which
     will have to be paid prior to the establishment of the escrow. Accordingly,
     $4.0 million of the license fee will be recognized ratably over the first
     three years following the effective date of the agreement, which
     approximates the time period during which Censtor expects to be incurring
     costs to maintain its patents and which also reflects management estimate
     of the reduction in potential exposure from the effective date of the
     Agreement until the establishment of the escrow fund. Subsequent amounts
     will be recognized as the escrow fund is reduced. Therefore, the pro forma
     statement of operations include revenue recognized on the license of
     $1,333,333 and $1,000,000 for the year ended June 30, 1995 and the nine
     months ended March 31, 1996, respectively.
