or (ii) the breach of any covenant prior to the Closing made by the Company

<PAGE>

action, suits, settlements and judgments of every nature, including the

         8.4    Indemnity Procedures.

                8.4.1 Claim and Dispute Procedures.

                (a) In the event that at any time or from time to time after the
Closing Date a person or entity entitled to indemnification pursuant to Section
8.2 or Section 8.3 (any such person or entity, an "Indemnitee") shall sustain
Damages against which such Indemnitee is indemnified under this Agreement, such
Indemnitee shall promptly provide written notice (a "Claim Notice") to each
party required to provide such indemnification (each such party, the
"Indemnitor") describing in reasonable detail the facts giving rise to any
claims for indemnification hereunder and shall include in such Claim Notice (if
then known) the amount or the method of computation of the amount of such claim
for indemnification; provided, that a Claim Notice in respect of any action at
law or suit in equity by or against a third party as to which indemnification
will be sought shall be given promptly after the Indemnitee receives written
notice of the commencement of such action or suit, but the failure so to notify
the Indemnitor shall not relieve it of any liability that it may have to any
Indemnitee, except to the extent the Indemnitor demonstrates that the defense of
such action is or has been prejudiced thereby.

                (b) If applicable, the Indemnitor shall have thirty days after
the receipt of any Claim Notice pursuant hereto to (i) agree to the amount or
method of determination set forth in the Claim Notice and to pay such amount to
such Indemnitee in immediately available funds or (ii) provide such Indemnitee
with notice that it disagrees with the amount or method of determination set
forth in the Claim Notice (the "Dispute Notice"). Within fifteen days after the
giving of the Dispute Notice, a representative of Indemnitor and such Indemnitee
shall negotiate in a bona fide attempt to resolve the matter. In the event that
the controversy is not resolved within thirty days of the giving of the Dispute
Notice, the controversy shall be resolved by a single arbitrator pursuant to
binding arbitration in San Francisco County, California, pursuant to the rules
and procedures of the Judicial Arbitration and Mediation Services ("JAMS"), San
Francisco, California.

                8.4.2 Third Party Claims. In case any proceeding shall be
brought against an Indemnitee and it shall give notice to the Indemnitor of the
commencement thereof in accordance with Section 8.4.1(a) above, the Indemnitor
shall be entitled to participate therein and, to the extent that it shall wish
(unless the Indemnitor is also a party to such proceeding and the Indemnitee
determines in good faith that joint representation would be inappropriate) to
assume the defense thereof with counsel which is reasonably satisfactory to such
Indemnitee and, after notice from the Indemnitor to such Indemnitee of its
election so to assume the defense thereof, the Indemnitor shall not be liable to
such Indemnitee under such Section for any fees of such

                                       24

<PAGE>

counsel or any other expenses with respect to the defense of such
proceeding, in each case, subsequently incurred by such Indemnitee in connection
with the defense thereof. If an Indemnitor assumes the defense of such
proceeding, (a) no compromise or settlement thereof may be effected by the
Indemnitor without the Indemnitee's reasonable consent unless (i) there is no
finding or admission of any violation by the Indemnitee of law or any violation
by the Indemnitee of the rights of any person or entity and no effect on any
other claims that may be made by the Indemnitee against the Indemnitee, and (ii)
the sole relief provided is monetary damages that are paid in full by the
Indemnitor; and (b) the Indemnitor shall have no liability with respect to any
compromise or settlement thereof effected without its consent (which shall not
be unreasonably withheld). If notice is given to an Indemnitor of the
commencement of any proceeding and it does not, within twenty (20) business days
after the Indemnitee's notice is given, give notice to the Indemnitee of its
election to assume the defense thereof, the Indemnitor shall be bound by any
determination made in such action or any compromise or settlement thereof
effected by the Indemenitee; provided, however, that any such determination,
compromise or settlement is made or taken in good faith, based upon the relevant
facts and circumstances. Notwithstanding the foregoing, if an Indemnitee
determines in good faith that there is a reasonable probability that a
proceeding may adversely affect it or its Affiliates, other than as a result of
monetary damages, such Indemnitee may, by notice to the Indemnitor, assume the
exclusive right to defend, compromise or settle such proceeding, but the
Indemnitor shall not be bound by any determination of a proceeding so defended
or any compromise or settlement thereof effected without its consent (which
shall not be unreasonably withheld.

         8.5    Exclusive Remedy. Subject to Section 8.6.4, conditioned upon
the occurrence of, and from and after, the Effective Time, the indemnification
obligations under this Agreement shall be the exclusive and sole remedy
available to the parties and shall be in lieu of any other remedies or rights
available to the parties, at law or in equity, with respect to any claims,
disputes, conflicts, damages or otherwise arising out of or related to this
Agreement and the Merger contemplated hereby. Nothing in this Section 8.5 or
elsewhere in this Agreement shall limit any party's rights or remedies, at law
or in equity, if the Effective Time does not occur or this Agreement is
terminated prior to the Effective Time, for any reason.

         8.6    Limitations on Indemnification.

                8.6.1 Except as set forth in Section 8.6.4, no indemnification
shall be payable pursuant to Section 8.2 or Section 8.3 after the Expiration
Date, except with respect to (i) claims made prior to the Expiration Date, but
not resolved by the Expiration Date and (ii) claims not subject to the
Expiration Date.

                8.6.2 Except as set forth in the next sentence and Section
8.6.4, Purchaser and its Affiliates shall not be entitled to recover Purchaser
Damages hereunder unless and until the aggregate Purchaser Damages exceed
$250,000 (the "Threshold Amount"), whereupon Purchaser shall be entitled to
recovery of all Purchaser Damages suffered or incurred by Purchaser and its
affiliates, including, without limitation, all such Purchaser Damages below the
Threshold Amount.

                8.6.3 Except as set forth in Section 8.6.4, (a) the aggregate
liability of the Company and Read-Rite for Purchaser Damages under Section 8.2.1
shall not exceed

                                       25

<PAGE>

$10,000,000, and (b) neither Read-Rite nor any Investor shall have any
liability for Purchaser Damages under Section 8.2.2 in excess of the portion of
the Consideration received by such Shareholder.

                8.6.4 Nothing in this Article 8 or elsewhere in this Agreement
shall limit, in any manner (whether by time, amount, procedure or otherwise),
any party's liability or responsibility, at law or in equity, due to or arising
from any intentional misrepresentation or fraud by such party. For the avoidance
of doubt, no party shall have any liability or responsibility for the fraud or
intentional misrepresentation of any other party.

         8.7    Application of Retained Consideration. From and after the
Effective Time, without limiting Read-Rite's liability for any Purchaser Damages
(or Purchaser's recourse therefore) for which Read-Rite is responsible under
Section 8.2.1 or Section 8.2.2, Purchaser may apply all or any portion of the
Retained Consideration in satisfaction of such Purchaser Damages. Purchaser and
Read-Rite agree that, as and when claims for such Purchaser Damages are resolved
in accordance with Section 8.4 above, such Purchaser Damages shall be satisfied
first from the Retained Consideration, if and to the extent the Retained
Consideration (or any portion thereof) continues to be (a) held by Purchaser in
accordance with the next sentence, and (b) not applied to other indemnification
obligations for Purchaser Damages. One (1) year after the Closing Date,
Purchaser shall pay to Read-Rite the Retained Consideration minus any portion
thereof then reasonably estimated by Purchaser to satisfy any then-outstanding
claims for Purchaser Damages. Any Retained Consideration retained by Purchaser
more than one (1) year after the Closing date (in accordance with the preceding
sentence), and not ultimately applied in satisfaction of Purchaser Damages shall
be promptly paid to Read-Rite.

                                   ARTICLE 9
                                  TERMINATION

                9.1.2 By Purchaser or the Company if

                (a) there shall be a final nonappealable order of a federal or
state court in effect that would prevent consummation of the Merger;

                (b) the Closing has not occurred on or prior to April 29, 2002,
for any reason other than the breach of any provision of this Agreement by (i)
the Purchaser, in the event of a termination by the Purchaser, or (ii) the
Company, Read-Rite or any Investor, in the event of a termination by the
Company; or

this Agreement pursuant to Section 9.1, this Agreement, except for the
provisions of Articles 8, 9 and 10 shall forthwith become void and be of no
effect, without any liability on the part of any party or its directors,
officers or stockholders. Notwithstanding the foregoing, nothing in this Section
9.2 shall relieve any party to this Agreement of liability for breach of this
Agreement.

                9.2.2 In the event of termination of this Agreement by the
Company pursuant to Section 9.1.2(c), but for no other reason, at the Company's
option, all principal and interest outstanding under the Loan (as defined in
that certain Loan Agreement dated as of April 10, 2002, between the Company and
the Purchaser), shall be converted into shares of Series B Preferred, at the
conversion rate of $0.25 per share. The Purchaser shall have all rights with
respect to such shares (including, without limitation, registration rights) as
it currently holds with respect to its current shares of Series B Preferred.

acknowledge and agree that any and all shares of Common Stock issuable upon

threatened breach.

         10.3   Finders and Brokers. Each party hereby represents and warrants
to the others that neither it nor its representatives have taken, nor will they

with any provision of this Agreement may be expressly waived in writing by (a)
Purchaser or (b) the Company, Read-Rite and the Investors, respectively, but
such waiver or failure to insist upon strict compliance with such provision
shall not operate as a waiver of, or estoppel with respect to, any subsequent or
other failure. No failure to exercise and no delay in exercising any right,
remedy, or power hereunder shall operate as a waiver thereof, nor shall any
single or partial exercise of any right, remedy, or power hereunder preclude any
other or further exercise thereof or the exercise of any other right, remedy, or
power provided herein or by law or in equity. The waiver by any party of

                                       28

<PAGE>

waiver of the act or condition itself.

expenses (including the fees of any attorneys, accountants, appraisers or others
engaged by such party) in connection with this Agreement and the transactions
