<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;The Delaware General Corporation Law (the "DGCL") permits a corporation to indemnify officers, directors, employees and agents for actions taken
in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interests of the corporation, and with respect to any criminal action, which they had no reasonable cause
to believe was unlawful. The DGCL provides that a corporation may advance expenses of defense (upon receipt of a written undertaking to reimburse the corporation if indemnification is not appropriate)
and must reimburse a successful defendant for expenses, including attorney's fees, actually and reasonably incurred, and permits a corporation to purchase and maintain liability insurance for its
directors and officers. The DGCL provides that indemnification may not be made for any claim, issue or matters as to which a person has been adjudged by a court of competent jurisdiction, after
exhaustion of all appeals therefrom, to be liable to the corporation, unless and only to the extent a court determines that the person is entitled to indemnity for such expenses as the court deems
proper. </FONT></P>

<P><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;The
Certificate of Incorporation of the Company (the "Certificate") provides that each person who is involved in any actual or threatened action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he or she is or was a director of the Company, or is or was serving at the request of the Company as a director of another
corporation or of a partnership, joint venture, trust, or other enterprise, will be indemnified by the Company, and that each person who is so involved by reason of the fact that he or she was an
officer, agent of the Company, or is or was serving at the request of the Company as an officer, agent or employee of another corporation, or of a partnership, joint venture, trust or other
enterprise, may be indemnified by the Company in accordance with the DGCL. The indemnification rights conferred by the Certificate are not exclusive of any other right to which persons seeking
indemnification may be entitled under any law, bylaw, agreement, vote </FONT></P>

as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Company, the Company has
been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful
defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by
the final adjudication of such issue. </FONT></P>

The documents listed in (a) through (c) below are incorporated by reference in this Registration Statement, and all documents subsequently filed
by North American Scientific, Inc. (the "Company") pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, 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 thereof from the date of filing of such documents:
(a)
The
Company's annual report on Form 10-K for the year ended October 31, 2000.
(b)
The
Company's quarterly reports on Form 10-Q for the quarters ended January 31, 2001 and April 30, 2001.
(c)
The
description of the Company's Common Stock which is contained in the Registration Statement on Form 10-SB filed August 22, 1995, File

The validity of the shares of Common Stock offered hereby will be passed upon by D'Ancona & Pflaum LLC, Chicago, Illinois. Mr. Allan J. Reich, a

Company's Common Stock, which ownership is not material.
Item 6. Indemnification of Directors and Officers.
The Delaware General Corporation Law (the "DGCL") permits a corporation to indemnify officers, directors, employees and agents for actions taken
in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interests of the corporation, and with respect to any criminal action, which they had no reasonable cause
to believe was unlawful. The DGCL provides that a corporation may advance expenses of defense (upon receipt of a written undertaking to reimburse the corporation if indemnification is not appropriate)
and must reimburse a successful defendant for expenses, including attorney's fees, actually and reasonably incurred, and permits a corporation to purchase and maintain liability insurance for its
directors and officers. The DGCL provides that indemnification may not be made for any claim, issue or matters as to which a person has been adjudged by a court of competent jurisdiction, after
exhaustion of all appeals therefrom, to be liable to the corporation, unless and only to the extent a court determines that the person is entitled to indemnity for such expenses as the court deems
proper.
The
Certificate of Incorporation of the Company (the "Certificate") provides that each person who is involved in any actual or threatened action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he or she is or was a director of the Company, or is or was serving at the request of the Company as a director of another
corporation or of a partnership, joint venture, trust, or other enterprise, will be indemnified by the Company, and that each person who is so involved by reason of the fact that he or she was an
officer, agent of the Company, or is or was serving at the request of the Company as an officer, agent or employee of another corporation, or of a partnership, joint venture, trust or other
enterprise, may be indemnified by the Company in accordance with the DGCL. The indemnification rights conferred by the Certificate are not exclusive of any other right to which persons seeking
indemnification may be entitled under any law, bylaw, agreement, vote
of stockholders or disinterested directors or otherwise. The Company has purchased and maintains insurance on behalf of its directors, officers, employees and agents.
Item 7. Exemption from Registration Claimed.
Not Applicable.
Item 8. Exhibits.
4.1
Certificate
of Incorporation of the Corporation, incorporated by reference to Exhibit 3(i) of the Company's Registration Statement on
Form 10-SB, filed August 22, 1995.

Item 9. Undertakings.
The Company hereby undertakes:
(1)
To
file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
(i)
To
include any prospectus required by section 10(a)(3) of the Securities Act of 1933;
(ii)
To
reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement;
(iii)
To
include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;
Provided, however
, that paragraphs (1)(i) and 1(ii) do not apply if the registration statement is on Form S-3,
Form S-8 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports
filed by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.
(2)
That,
for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
(3)
To
remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
The
Company hereby undertakes that, for the purposes of determining any liability under the Securities Act of 1933, each filing of the Company's annual report pursuant to
section 13(a) or
section 15(d) of the Securities 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.
Insofar
as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Company, the Company has
been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful
defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Company will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by
the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all the
requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of
