is or was serving at the request of the Registrant, (ii)&nbsp;any actual, alleged or suspected
act or failure to act by the indemnitee in respect of any business, transaction,
communication, filing, disclosure or other activity of the Registrant or any other entity
or enterprise referred to in clause (i)&nbsp;above, or (iii)&nbsp;the indemnitee&#146;s status as a
current or former director, officer, employee or agent of the Registrant or as a current or
former director, officer, employee, member, manager, trustee or agent of the Registrant or
any other entity or enterprise referred to in clause (i)&nbsp;above or any actual, alleged or
suspected act or failure to act by the indemnitee in connection with any obligation or
restriction imposed upon the indemnitee by reason of such status. The indemnification
agreements provide that the indemnitee shall have the right to advancement by the
Registrant prior to the final disposition of any indemnifiable claim of any and all actual
and reasonable expenses relating to, arising out of or resulting from any indemnifiable
claim paid or incurred by the indemnitee. For the duration of an indemnitee&#146;s service as a
director and/or officer of the Registrant and for a reasonable period of time thereafter,
which such period may be determined by the Registrant in its sole discretion, the
Registrant is obligated to use commercially reasonable efforts (taking into account the
scope and amount of coverage available relative to the cost thereof) to cause to be
maintained in effect policies of directors&#146; and officers&#146; liability insurance providing
coverage for directors and/or officers of the Registrant that is substantially comparable
in scope and amount to that provided by the Registrant&#146;s current policies of directors&#146; and
officers&#146; liability insurance.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">The Registrant also maintains a directors and officers insurance policy pursuant to which
its directors and officers are insured against liability for actions in their capacity as

Item 6.
Indemnification of Directors and Officers.
Delaware law and the Registrant's Certificate of Incorporation provide that the Registrant
will, under certain situations, indemnify any director, officer, employee or agent of
Polypore International, Inc. made or threatened to be made a party to a proceeding, by
reason of the former or present official capacity of the person, against judgments,
penalties, fines, settlements and reasonable expenses, including attorney's fees, incurred
by the person in connection with the proceeding if certain statutory standards are met. Any
such person is also entitled, subject to certain limitations, to payment or reimbursement of
reasonable expenses in advance of the final disposition of the proceeding. A proceeding
means a threatened, pending or completed civil, criminal, administrative, arbitration or
investigative proceeding, including one by or in the right of Polypore International, Inc.
Reference is made to Section 145 of the Delaware General Corporation Law for a full
statement of these indemnification rights.
The Registrant has entered into director and officer indemnification agreements with
certain of its directors and officers. The indemnification agreements provide that the
Registrant will indemnify, defend and hold harmless the indemnitees, to the fullest extent
permitted or required by the laws of the State of Delaware, against any and all claims
based upon, arising out of or resulting from (i) any actual, alleged or suspected act or
failure to act by the indemnitee in his or her capacity as a director, officer, employee or
agent of the Registrant or as a director, officer, employee, member, manager, trustee or
agent of any other corporation, limited liability company, partnership, joint venture,
trust or other entity or enterprise, whether or not for profit, as to which the indemnitee
is or was serving at the request of the Registrant, (ii) any actual, alleged or suspected
act or failure to act by the indemnitee in respect of any business, transaction,
communication, filing, disclosure or other activity of the Registrant or any other entity
or enterprise referred to in clause (i) above, or (iii) the indemnitee's status as a
current or former director, officer, employee or agent of the Registrant or as a current or
former director, officer, employee, member, manager, trustee or agent of the Registrant or
any other entity or enterprise referred to in clause (i) above or any actual, alleged or
suspected act or failure to act by the indemnitee in connection with any obligation or
restriction imposed upon the indemnitee by reason of such status. The indemnification
agreements provide that the indemnitee shall have the right to advancement by the
Registrant prior to the final disposition of any indemnifiable claim of any and all actual
and reasonable expenses relating to, arising out of or resulting from any indemnifiable
claim paid or incurred by the indemnitee. For the duration of an indemnitee's service as a
director and/or officer of the Registrant and for a reasonable period of time thereafter,
which such period may be determined by the Registrant in its sole discretion, the
Registrant is obligated to use commercially reasonable efforts (taking into account the
scope and amount of coverage available relative to the cost thereof) to cause to be
maintained in effect policies of directors' and officers' liability insurance providing
coverage for directors and/or officers of the Registrant that is substantially comparable
in scope and amount to that provided by the Registrant's current policies of directors' and
officers' liability insurance.
The Registrant also maintains a directors and officers insurance policy pursuant to which
its directors and officers are insured against liability for actions in their capacity as
directors and officers.

Undertakings.
(a)
The undersigned Registrant 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 this Registration Statement (or most recent
post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth
in this Registration Statement. Notwithstanding the foregoing, any
increase or decrease in the volume of securities offered (if the total
dollar value of securities offered would not exceed that which was
registered) and any deviation from the low or high end of the estimated
maximum offering range may be reflected in the form of prospectus filed
with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than a 20 percent change
in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement; and
(iii)
To include any material information with respect to the
plan of distribution not previously disclosed in this Registration
Statement or any material change to such information in this
Registration Statement;
3
Table of Contents
Provided, however
, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if
the information required to be included in a post-effective amendment by those paragraphs
is contained in reports filed with or furnished to the Commission by the Registrant
pursuant to Section 13 or Section 15(d) of the Exchange Act 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.
(b)
The undersigned Registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Registrant's annual report
pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to Section 15(d) of
the Exchange Act) 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.
(c)
Insofar as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the Registrant pursuant to
the foregoing provisions, or otherwise, the Registrant has been advised that in the
opinion of the Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the Registrant of
expenses incurred or paid by a director, officer or controlling person of the
Registrant 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 Registrant 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 and will be governed by the final adjudication of such issue.
