<P align="left" style="font-size: 10pt">Item&nbsp;6. Indemnification of Directors and Officers.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Komag&#146;s Certificate of Incorporation limits the liability of directors to
the maximum extent permitted by Delaware law. Delaware law provides that
directors of a company will not be personally liable for monetary damages for
breach of their fiduciary duties as directors, except for liability (i)&nbsp;for any
breach of their duty of loyalty to the company or its stockholders, (ii)&nbsp;for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (iii)&nbsp;for unlawful payments of dividends or
unlawful stock repurchases or redemptions as provided in Section&nbsp;174 of the
Delaware General Corporation Law, or (iv)&nbsp;for any transaction from which the
director derived an improper personal benefit.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Komag&#146;s Bylaws provide that Komag shall indemnify its officers and
directors and may indemnify its employees and other agents to the fullest
extent permitted by law. Komag believes that indemnification under its Bylaws
covers at least negligence and gross negligence on the part of indemnified
parties. Komag&#146;s Bylaws also permit it to secure insurance on behalf of any
officer, director, employee or other agent for any liability arising out of his
or her actions in such capacity, regardless of whether the provisions of the
General Corporation Law of Delaware would permit indemnification.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Komag has entered into agreements to indemnify its directors and officers,
in addition to the indemnification provided for under Delaware law, and in
Komag&#146;s Certificate of Incorporation and Bylaws. These agreements, among other
things, indemnify Komag&#146;s directors and officers for certain expenses
(including attorneys&#146; fees), judgments, fines and settlement amounts incurred
by any such person in any action or proceeding, including any action by or in
the right of Komag, arising out of such person&#146;s services as a director or
officer of Komag, any subsidiary of Komag, or any other company or enterprise
to which the person provides services at the request of Komag. Komag believes
that these provisions and agreements are necessary to attract and retain
qualified persons as directors and officers.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The limited liability and indemnification provisions in our Certificate of
Incorporation and Bylaws may discourage stockholders from bringing a lawsuit
against our directors for breach of their fiduciary duty and may reduce the
likelihood of derivative litigation against our directors and officers, even
though a derivative action, if successful,

This Registration Statement shall also cover any additional shares of Common Stock which become issuable
under the Registrant's 2002 Qualified Stock Plan (the "Plan") by reason of any stock dividend, stock split,
recapitalization or any other similar transaction effected without the Registrant's receipt of consideration
which results in an increase in the number of outstanding shares of the Registrant's Common Stock.

The Proposed Maximum Offering Price Per Share was estimated in part pursuant to Rule 457(h) under the
Securities Act, and, in part, pursuant to Rule 457(c) under the Securities Act. With respect to 650,000 shares
which are subject to outstanding options to purchase Common Stock under the Plan, the Proposed Maximum Offering
Price Per Share was estimated pursuant to Rule 457(c) whereby the per share price was determined by reference to
the average of the high and low prices for the Common Stock as reported by The Nasdaq National Market on June
15, 2004, which average was $15.10.

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT
Item 3. Incorporation of Documents by Reference.
The following documents and information previously filed with the
Securities and Exchange Commission by Komag, Incorporated ("Komag") are hereby
incorporated by reference into this Registration Statement and, pursuant to
Rule 428 promulgated under the Securities Act of 1933, as amended, into the
Prospectuses relating to this Registration Statement:
(1)
Komag's Form 10-K Annual Report for the fiscal year ended
December 28, 2003, and Quarterly Report on Form 10-Q for the
quarter ended April 4, 2004.
All documents subsequently filed by Komag pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended, prior
to the filing of a post-effective amendment which indicates that all securities
offered have been sold or which deregisters all securities then remaining
unsold, shall be deemed to be incorporated by reference in this registration
statement and to be part hereof from the date of filing such documents.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
Komag's Certificate of Incorporation limits the liability of directors to
the maximum extent permitted by Delaware law. Delaware law provides that
directors of a company will not be personally liable for monetary damages for
breach of their fiduciary duties as directors, except for liability (i) for any
breach of their duty of loyalty to the company or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or
a knowing violation of law, (iii) for unlawful payments of dividends or
unlawful stock repurchases or redemptions as provided in Section 174 of the
Delaware General Corporation Law, or (iv) for any transaction from which the
director derived an improper personal benefit.
Komag's Bylaws provide that Komag shall indemnify its officers and
directors and may indemnify its employees and other agents to the fullest
extent permitted by law. Komag believes that indemnification under its Bylaws
covers at least negligence and gross negligence on the part of indemnified
parties. Komag's Bylaws also permit it to secure insurance on behalf of any
officer, director, employee or other agent for any liability arising out of his
or her actions in such capacity, regardless of whether the provisions of the
General Corporation Law of Delaware would permit indemnification.
Komag has entered into agreements to indemnify its directors and officers,
in addition to the indemnification provided for under Delaware law, and in
Komag's Certificate of Incorporation and Bylaws. These agreements, among other
things, indemnify Komag's directors and officers for certain expenses
(including attorneys' fees), judgments, fines and settlement amounts incurred
by any such person in any action or proceeding, including any action by or in
the right of Komag, arising out of such person's services as a director or
officer of Komag, any subsidiary of Komag, or any other company or enterprise
to which the person provides services at the request of Komag. Komag believes
that these provisions and agreements are necessary to attract and retain
qualified persons as directors and officers.
The limited liability and indemnification provisions in our Certificate of
Incorporation and Bylaws may discourage stockholders from bringing a lawsuit
against our directors for breach of their fiduciary duty and may reduce the
likelihood of derivative litigation against our directors and officers, even
though a derivative action, if successful,

might otherwise benefit us and our stockholders. Moreover, a
stockholder's investment in us may be adversely affected to the extent we pay
the costs of settlement or damage awards against our directors and officers
under these indemnification provisions.

Item 9. Undertakings.
(1)
Komag hereby undertakes:
(a)
To file, during any period in which offers or sales
are being made, a post-effective amendment to this registration
statement to include any material information with respect to
the plan of distribution not previously disclosed in the
registration statement or any material change to such
information in the registration statement.
(b)
That, for the purpose of determining any liability
under the Securities Act of 1933, as amended, each such
post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered
therein, and the offering of such securities at that time shall
be deemed to be the initial bona fide offering thereof.
(c)
To remove from registration by means of
post-effective amendment any of the securities being registered
which remain unsold at the termination of the offering.
(2)
Komag hereby undertakes that, for purposes of determining
any liability under the Securities Act 1933, as amended, each
filing of Komag's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act of 1934, as amended,
(and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act of
1934) that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of
such securities at that time shall be deemed to be the initial bona
fide offering thereof.
(3)
Insofar as indemnification for liabilities arising under
the Securities Act of 1933, as amended, may be permitted to
directors, officers and controlling persons of Komag pursuant to
the Delaware General Corporation Law, the Certificate of
Incorporation or the Bylaws of Komag, indemnification agreements
entered into between Komag and its officers and directors, or
otherwise, Komag has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against
public policy as expressed in the Securities Act of 1933, as
amended, and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the
payment by Komag of expenses incurred or paid by a director,
officer or controlling person in the successful defense of any
action, suit or
II-2

proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered hereunder,
Komag will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act of 1933, as
amended, and will be governed by the final adjudication of such
issue.
