case may be.

Notwithstanding the
foregoing, in connection with the purchase by Polypore or any Subsidiary of any
business, the term “Indebtedness” will exclude post-closing payment adjustments
to which the seller may become entitled to the extent such payment is
determined by a final closing balance sheet or such payment depends on the

thereafter becomes fixed and determined, the amount is paid within 60 days
thereafter.

For purposes hereof, the “maximum
fixed repurchase price” of any Disqualified Capital Stock which does not have a
fixed repurchase price shall be calculated in accordance with the terms of such
Disqualified Capital Stock as if such Disqualified Capital Stock were purchased
on any date on which Indebtedness shall be required to be determined pursuant
to this Agreement, and if such price is based upon, or measured by, the fair
market value of such Disqualified Capital Stock, such fair market value shall
be determined reasonably and in good faith by the Board of Directors of the
issuer of such Disqualified Capital Stock. For the purposes of calculating the
amount of Indebtedness of a Securitization Entity outstanding as of any date,
the face or notional amount of any interest in receivables or equipment that is
outstanding as of such date shall be deemed to be Indebtedness but any such
interests held by Affiliates of such Securitization Entity shall be excluded for
purposes of such calculation.

the last day of the next preceding Interest Period applicable to such
Eurocurrency Loan and ending one, two, three or six or (if agreed to by all

representations and warranties set forth herein and in the other Loan
documents, to make Incremental Term Loans to Polypore, in an aggregate
principal amount not to exceed its Incremental Term Loan Commitment.  Amounts paid or prepaid in respect of
Incremental Term Loans may not be reborrowed.

SECTION
2.2.  Loans.  (a) 
Each Loan (other than Swingline Loans) shall be made as part of a
Borrowing consisting of Loans made by the Lenders ratably in accordance with
their applicable Commitments; provided, however, that the failure
of any Lender to make any Loan shall not in itself relieve any other Lender of
its obligation to lend hereunder (it being understood, however, that no Lender
shall be responsible for the failure of any other Lender to make any Loan
required to be made by such other Lender). 
Except for Swingline Loans and Loans deemed made pursuant to
Section 2.2(f), the Loans comprising any Borrowing shall be in an
aggregate principal amount that is (i) (A) in the case of a Revolving
Borrowing, an integral multiple of $1,000,000 and not less than $1,000,000,
(B) in the case of a US$ Term Loan Borrowing or an Incremental Term Loan
Borrowing, an integral multiple of $1,000,000 and not less than $5,000,000
(except with respect to any Incremental Term Loan Borrowing, to the extent
otherwise provided in the related Incremental Term Loan Assumption Agreement)
and (C) in the case of a Euro Term Loan Borrowing, an integral multiple of €1,000,000
and not less than €5,000,000 or (ii) in the case of any Borrowing, equal
to the remaining available balance of the applicable Commitments.

(b)                                 Subject
to Section 2.8, each Borrowing shall be comprised entirely of Eurocurrency
Loans or, with respect to Loans denominated in Dollars, ABR Loans, as the
Borrower may request pursuant to Section 2.3.  Each Lender may at its option make any
Eurocurrency Loan by causing any domestic or foreign branch or Affiliate of
such Lender to make such Loan; provided,
that any exercise of such option shall not affect the obligation of the
Borrower to repay such Loan in accordance with the terms of this
Agreement.  Borrowings of more than one
Type may be outstanding at the same time; provided, however,
that the Borrower shall not be entitled to request any Borrowing that, if made,
would result in more than ten (10) Eurocurrency Borrowings outstanding
hereunder at any time.  For purposes of
the foregoing, Borrowings having different Interest Periods, regardless of
whether they commence on the same date, shall be considered separate
Borrowings.

 36
 

(c)                                  Except
with respect to Swingline Loans and Loans made pursuant to Section 2.2(f),
each Lender shall make each Loan to be made by it hereunder on the proposed
date thereof by wire transfer of immediately available funds to the Funding
Office not later than 12:00 (noon), Local Time, and the Administrative Agent
shall promptly transfer the amounts so received to the account designated by
the Borrower in the applicable Borrowing Request or, if a Borrowing shall not
occur on such date because any condition precedent herein specified shall not
have been met, return the amounts so received to the respective Lenders.

(d)                                 Unless
the Administrative Agent shall have received notice from a Lender prior to the
date of any Borrowing that such Lender will not make available to the
Administrative Agent such Lender’s portion of such Borrowing, the
Administrative Agent may assume that such Lender has made such portion
available to the Administrative Agent on the date of such Borrowing in
accordance with paragraph (c) above and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on such date a
corresponding amount.  If the
Administrative Agent shall have so made funds available then, to the extent
that such Lender shall not have made such portion available to the
Administrative Agent, such Lender and the Borrower severally agree to repay to
the Administrative Agent forthwith on demand such corresponding amount together
with interest thereon, for each day from the date such amount is made available
to the Borrower until the date such amount is repaid to the Administrative
Agent at (i) in the case of the Borrower, the interest rate applicable at the
time to the Loans comprising such Borrowing and (ii) in the case of such
Lender, a rate determined by the Administrative Agent to represent its cost of
overnight or short-term funds (which determination shall be conclusive absent
manifest error).  If such Lender shall
repay to the Administrative Agent such corresponding amount, such amount shall
constitute such Lender’s Loan as part of such Borrowing for purposes of this
Agreement.

(e)                                  Notwithstanding
any other provision of this Agreement, Polypore shall not be entitled to
request any Revolving Credit Borrowing if the Interest Period requested with
respect thereto would end after the Revolving Credit Maturity Date.

(f)                                    If
the Issuing Bank shall not have received from Polypore the payment required to
be made by Section 2.22(e) within the time specified in such Section, the
Issuing Bank will promptly notify the Administrative Agent of the L/C
Disbursement and the Administrative Agent will promptly notify each Revolving
Credit Lender of such L/C Disbursement and its Pro Rata Percentage
thereof.  Each Revolving Credit Lender
shall pay by wire transfer of immediately available funds to the Administrative
Agent not later than 2:00 p.m., New York City time, on such date (or, if such
Revolving Credit Lender shall have received such notice later than 12:00
(noon), New York City time, on any day, not later than 10:00 a.m., New York
City time, on the immediately following Business Day), an amount equal to such
Lender’s Pro Rata Percentage of such L/C Disbursement (it being understood that
such amount shall be deemed to constitute an ABR Revolving Loan of such Lender
and such payment shall be deemed to have reduced the L/C Exposure), and the
Administrative Agent will promptly pay to the Issuing Bank amounts so received
by it from the Revolving Credit Lenders. 
The Administrative Agent will promptly pay to the Issuing Bank any
amounts received by it from Polypore pursuant to Section 2.22(e) prior to
the time that any Revolving Credit Lender makes any payment pursuant to this
paragraph (f); any such amounts received by the Administrative Agent thereafter
will be promptly remitted by the Administrative Agent to the Revolving Credit
Lenders that shall have made such payments and to the Issuing Bank, as their
interests may appear.  If any Revolving
Credit Lender shall not have made its Pro Rata Percentage of such L/C
Disbursement available to the Administrative Agent as provided above, such
Lender and Polypore severally agree to pay interest on such amount, for each
day from and including the date such amount is required to be paid in
accordance with this paragraph to but excluding the date such amount is paid,
to the Administrative Agent for the account of the Issuing Bank at (i) in the
case of Polypore, a rate per annum equal to the interest rate applicable to
Revolving Loans pursuant to Section 2.6(a), and (ii) in the case of

 37
 

such Lender,
for the first such day, the Federal Funds Effective Rate, and for each day
thereafter, the Alternate Base Rate.

SECTION
2.3.  Borrowing Procedure.  In order to request a Borrowing (other than a
Swingline Loan or a deemed Borrowing pursuant to Section 2.2(f), as to
which this Section 2.3 shall not apply), the Borrower shall hand deliver
or fax to the Administrative Agent (or give telephonic notice promptly confirmed
by written notice) a duly completed Borrowing Request (a) in the case of a
Eurocurrency Borrowing, not later than 12:00 (noon), Local Time, three Business
Days before a proposed Borrowing, and (b) in the case of an ABR Borrowing, not
later than 12:00 (noon), New York City time, one Business Day before a proposed
Borrowing.  Each Borrowing Request shall
be irrevocable, shall be signed by or on behalf of the Borrower and shall
specify the following information: (i) whether the Borrowing then being requested
is to be a US$ Term Loan Borrowing, a Euro Term Loan Borrowing, an Incremental
Term Loan Borrowing or a Revolving Credit Borrowing, whether such Borrowing is
denominated in Dollars, and whether such Borrowing is to be a Eurocurrency
Borrowing or an ABR Borrowing; (ii) the date of such Borrowing (which
shall be a Business Day); (iii) the number and location of the account to
which funds are to be disbursed; (iv) the amount of such Borrowing; and
(v) if such Borrowing is to be a Eurocurrency Borrowing, the Interest
Period with respect thereto; provided, however, that,
notwithstanding any contrary specification in any Borrowing Request, each
requested Borrowing shall comply with the requirements set forth in
Section 2.2.  If no election as to
the Type of Borrowing is specified in any such notice, then the requested
Borrowing shall be an ABR Borrowing.  If
no Interest Period with respect to any Eurocurrency Borrowing is specified in
any such notice, then the Borrower shall be deemed to have selected an Interest
Period of one month’s duration.  The
Administrative Agent shall promptly advise the applicable Lenders of any notice
given pursuant to this Section 2.3 (and the contents thereof), and of each
Lender’s portion of the requested Borrowing.

SECTION
2.4.  Evidence of Debt;
Repayment of Loans. 
(a)  The Borrower hereby
unconditionally promises to pay to each Lender, through the Administrative
Agent, (i) the principal amount of each Term Loan of such Lender as
provided in Section 2.11 and (ii) the then unpaid principal amount of
each Revolving Loan of such Lender on the Revolving Credit Maturity Date.  Polypore hereby promises to pay to the
Swingline Lender the then unpaid principal amount of each Swingline Loan on the
Revolving Credit Maturity Date.

(b)                                 Each
Lender shall maintain in accordance with its usual practice an account or
accounts evidencing the indebtedness of the Borrower to such Lender resulting
from each Loan made by such Lender from time to time, including the amounts of
principal and interest payable and paid to such Lender from time to time under
this Agreement.

(c)                                  The
Administrative Agent shall maintain accounts in which it will record (i) the
amount of each Loan made hereunder, the Type thereof and, if applicable, the
Interest Period applicable thereto, (ii) the amount of any principal or
interest due and payable or to become due and payable from the Borrower to each
Lender hereunder and (iii) the amount of any sum received by the Administrative
Agent hereunder from the Borrower or any Guarantor and each Lender’s share
thereof.

(d)                                 The
entries made in the accounts maintained pursuant to paragraphs (b) and (c)
above shall be prima facie evidence of the
existence and amounts of the obligations therein recorded; provided, however, that the failure of any
Lender or the Administrative Agent to maintain such accounts or any error
therein shall not in any manner affect the obligations of the Borrower to repay
the Loans in accordance with their terms.

(e)                                  Any
Lender may request that Loans made by it hereunder be evidenced by a promissory
note.  In such event, the Borrower shall
execute and deliver to such Lender a promissory note payable to

 38
 

such Lender
and its registered assigns and in a form and substance reasonably acceptable to
the Administrative Agent and the Borrower. Notwithstanding any other provision
of this Agreement, in the event any Lender shall request and receive such a
promissory note, the interests represented by such note shall at all times
(including after any assignment of all or part of such interests pursuant to
Section 9.4) be represented by one or more promissory notes payable to the
payee named therein or its registered assigns.

SECTION
2.5.  Fees.  (a) 
Polypore agrees to pay to each Lender, through the Administrative Agent,
on the last Business Day of March, June, September and December in each year
and on each date on which any Commitment of such Lender shall expire or be
terminated as provided herein, a commitment fee (a “Commitment Fee”)
equal to 0.50% per annum on the daily unused amount of the Commitments of such
Lender (other than the Swingline Commitment) during the preceding quarter (or
other period commencing with the Restatement Effective Date or ending with the
Revolving Credit Maturity Date or the date on which the Commitments of such
Lender shall expire or be terminated); provided that any commitment fee
accrued with respect to any of the Commitments of a Defaulting Lender during
the period prior to the time such Lender became a Defaulting Lender and unpaid
at such time shall not be payable by Polypore so long as such Lender shall be a
Defaulting Lender except to the extent that such commitment fee shall otherwise
have been due and payable by Polypore prior to such time; and provided, further,
that no commitment fee shall accrue on any of the Commitments of a Defaulting
Lender so long as such Lender shall be a Defaulting Lender.  All Commitment Fees shall be computed on the
basis of the actual number of days elapsed in a year of 360 days.  The Commitment Fee due to each Lender shall
commence to accrue on the Restatement Effective Date and shall cease to accrue
on the date on which the Commitment of such Lender shall expire or be
terminated as provided herein.  For
purposes of calculating Commitment Fees only, no portion of the Revolving
Credit Commitments shall be deemed utilized as a result of outstanding
Swingline Loans.

(b)                                 Polypore
agrees to pay to the Administrative Agent, for its own account, the
administration fees set forth in the Fee Letter at the times and in the amounts
specified therein (the “Administrative
Agent Fees”).

(c)                                  Polypore
agrees to pay (i) to each Revolving Credit Lender, through the Administrative
Agent, on each Fee Payment Date a fee (an “L/C Participation Fee”) calculated on such Lender’s Pro Rata
Percentage of the daily aggregate L/C Exposure (excluding the portion thereof
attributable to unreimbursed L/C Disbursements) during the preceding quarter
(or shorter period commencing with the Restatement Effective Date or ending
with the Revolving Credit Maturity Date or the date on which all Letters of
Credit have been canceled or have expired and the Revolving Credit Commitments
of all Lenders shall have been terminated) at a rate per annum equal to the
Applicable Percentage from time to time used to determine the interest rate on
Revolving Credit Borrowings comprised of Eurocurrency Loans pursuant to
Section 2.6, and (ii) to the Issuing Bank, for its own account, a fronting
fee of 0.25% per annum on the undrawn and unexpired amount of each Letter of
Credit, payable quarterly in arrears on each Fee Payment Date after the
issuance date (the “Issuing Bank
Fees”).  All L/C Participation
Fees and Issuing Bank Fees shall be computed on the basis of the actual number
of days elapsed in a year of 360 days.

(d)                                 All
Fees shall be paid in Dollars on the dates due, in immediately available funds,
to the Administrative Agent for distribution, if and as appropriate, among the
Lenders, except that the Issuing Bank Fees shall be paid directly to the
Issuing Bank.  Once paid, none of the
Fees shall be refundable under any circumstances.

SECTION
2.6.  Interest on Loans.  (a) 
Subject to the provisions of Section 2.7, the Loans comprising each
ABR Borrowing, including each Swingline Loan, shall bear interest (computed on
the basis of the actual number of days elapsed over a year of 365 or 366 days,
as the case may be, when the Alternate Base Rate

 39
 

is determined by reference to the Prime Rate and over
a year of 360 days at all other times and calculated from and including the
date of such Borrowing to but excluding the date of repayment thereof) at a
rate per annum equal to the Alternate Base Rate plus the Applicable Percentage
in effect from time to time.

(b)                                 Subject
to the provisions of Section 2.7, the Loans comprising each Eurocurrency
Borrowing shall bear interest (computed on the basis of the actual number of
days elapsed over a year of 360 days) at a rate per annum equal to the
Eurocurrency Rate for the Interest Period in effect for such Borrowing plus the
Applicable Percentage in effect from time to time.

(c)                                  Interest
on each Loan shall be payable to the applicable Lenders, through the
Administrative Agent, on the Interest Payment Dates applicable to such Loan
except as otherwise provided in this Agreement.  The applicable Alternate Base Rate or
Eurocurrency Rate for each Interest Period or day within an Interest Period, as
the case may be, shall be determined by the Administrative Agent, and such
determination shall be conclusive absent manifest error.

SECTION
2.7.  Default Interest.  Any amount (whether of principal, interest,
Fees or otherwise) not paid when due hereunder or under any other Loan Document
shall bear interest, to the extent permitted by law (after as well as before
judgment), payable on demand, (a) in the case of principal, at the rate
otherwise applicable thereto pursuant to Section 2.6 plus 2.00% per annum
and (b) in all other cases, at a rate per annum (computed on the basis of the
actual number of days elapsed over a year of 365 or 366 days, as the case may
be, when determined by reference to the Prime Rate and over a year of 360 days
at all other times) equal to the rate that would be applicable to an ABR Term
Loan plus 2.00% per annum.

SECTION
2.8.  Alternate Rate of
Interest.  In the
event, and on each occasion, that on the day two Business Days prior to the
commencement of any Interest Period for a Eurocurrency Borrowing the
Administrative Agent shall have determined that dollar deposits in the
principal amounts of the Loans comprising such Borrowing are not generally
available in the London interbank market, or that the rates at which such
dollar deposits are being offered will not adequately and fairly reflect the
cost to a majority in interest of the Lenders participating or to participate
in such Loan of making or maintaining its Eurocurrency Loan during such
Interest Period, or that reasonable means do not exist for ascertaining the
Eurocurrency Rate, the Administrative Agent shall, as soon as practicable
thereafter, give written or fax notice of such determination to the Borrower
and the Lenders.  In the event of any
such determination, until the Administrative Agent shall have advised the
Borrower and the Lenders that the circumstances giving rise to such notice no
longer exist, any request by the Borrower for a Eurocurrency Borrowing pursuant
to Section 2.3 or 2.10 shall be deemed to be a request for an ABR
Borrowing.  Each determination by the
Administrative Agent under this Section 2.8 shall be conclusive absent
manifest error.

SECTION
2.9.  Termination and Reduction
of Commitments.  (a)  The US$ Term Loan Commitments and the Euro
Term Loan Commitments shall automatically terminate at 5:00 p.m., New York City
time, on the Restatement Effective Date. The Revolving Credit Commitments, the
Swingline Commitment and the L/C Commitment shall automatically terminate on
the Revolving Credit Maturity Date.

(b)                                 Upon
at least three Business Days’ prior irrevocable written or fax notice (or
telephonic notice promptly confirmed by written notice) to the Administrative
Agent, the Borrower may at any time in whole permanently terminate, or from
time to time in part permanently reduce, the Term Loan Commitments or the
Revolving Credit Commitments; provided, however, that
(i) each partial reduction of the Term Loan Commitments or the Revolving
Credit Commitments shall be in an integral multiple of $1,000,000 and in a
minimum amount of $1,000,000 and (ii) the Total Revolving Credit
Commitment shall not be reduced to an amount that is less than the Aggregate
Revolving Credit Exposure at the time.

 40

(c)                                  Each
reduction in the Term Loan Commitments or the Revolving Credit Commitments
hereunder shall be made ratably among the Lenders in accordance with their
respective applicable Commitments.  The
Borrower shall pay to the Administrative Agent for the account of the
applicable Lenders, on the date of termination of the Commitments of any Class,
all accrued and unpaid Commitment Fees relating to such Class to but excluding
the date of such termination.

SECTION
2.10.  Conversion and
Continuation of Borrowings.  The Borrower shall have the right at any time
upon prior irrevocable notice to the Administrative Agent (a) not later
than 12:00 (noon), New York City time, one Business Day prior to
conversion, to convert any Eurocurrency Borrowing denominated in Dollars into
an ABR Borrowing, (b) not later than 12:00 (noon), New York City time,
three Business Days prior to conversion or continuation, to convert any ABR
Borrowing into a Eurocurrency Borrowing denominated in Dollars or to continue
any Eurocurrency Borrowing as a Eurocurrency Borrowing for an additional
Interest Period, and (c) not later than 12:00 (noon), Local Time,
three Business Days prior to conversion, to convert the Interest Period with
respect to any Eurocurrency Borrowing to another permissible Interest Period,
subject in each case to the following:

(i)  
each conversion or continuation shall be made pro rata among the Lenders in
accordance with the respective principal amounts of the Loans comprising the
converted or continued Borrowing;

(ii)  
if less than all the outstanding principal amount of any Borrowing shall be
converted or continued, then each resulting Borrowing shall satisfy the
limitations specified in Sections 2.2(a) and 2.2(b) regarding the principal
amount and maximum number of Borrowings of the relevant Type;

(iii)  
each conversion shall be effected by each Lender and the Administrative Agent
by recording for the account of such Lender the new Loan of such Lender
resulting from such conversion and reducing the Loan (or portion thereof) of
such Lender being converted by an equivalent principal amount; accrued interest
on any Eurocurrency Loan (or portion thereof) being converted shall be paid by
the Borrower at the time of conversion;

(iv)  
if any Eurocurrency Borrowing is converted at a time other than the end of the
Interest Period applicable thereto, the Borrower shall pay, upon demand, any
amounts due to the Lenders pursuant to Section 2.15; and

(v)  
after the occurrence and during the continuance of a Default specified in clause
(b) or (c) of Article VII (without regard to any applicable grace period in
such clause (c)), no outstanding Loan denominated in Dollars may be converted
into, or continued as, a Eurocurrency Loan.

Each notice pursuant to this Section 2.10 shall be irrevocable
and shall refer to this Agreement and specify (i) the identity, currency
denomination and amount of the Borrowing that the Borrower requests be
converted or continued, (ii) whether such Borrowing is to be converted to or
continued as a Eurocurrency Borrowing or an ABR Borrowing, (iii) if such notice
requests a conversion, the date of such conversion (which shall be a Business
Day) and (iv) if such Borrowing is to be converted to or continued as a
Eurocurrency Borrowing, the Interest Period with respect thereto.  If no Interest Period is specified in any
such notice with respect to any conversion to or continuation as a Eurocurrency
Borrowing, the Borrower shall be deemed to have selected an Interest Period of one
month’s duration.  The Administrative
Agent shall advise the Lenders of any notice given pursuant to this Section
2.10 and of each Lender’s portion of any converted or continued Borrowing.  If the Borrower shall not have given notice
in accordance with this Section 2.10 to continue any Eurocurrency Borrowing
into a subsequent

 41
 

Interest
Period (and shall not otherwise have given notice in accordance with this
Section 2.10 to convert such Borrowing), such Borrowing shall, at the end of
the Interest Period applicable thereto (unless repaid pursuant to the terms
hereof), automatically be converted into an ABR Borrowing.

SECTION
2.11.  Repayment of Term Loan
Borrowings.  (a)  The
Borrower shall pay to the applicable Lenders, through the Administrative Agent,
on the dates set forth below, or if any such date is not a Business Day, on the
next preceding Business Day (each such date being called a “Repayment Date”),
a principal amount of the US$ Term Loans and Euro Term Loans (as adjusted from
time to time pursuant to Sections 2.11(c), 2.12, 2.13(e) and 2.23(d))
equal to such Lender’s US$ Term Percentage or Euro Term Percentage, as the case
may be, multiplied by a percentage of the original aggregate principal amount
of the US$ Term Loans or the Euro Term Loans, as applicable, as set forth below
(together in each case with accrued and unpaid interest on the principal amount
to be paid to but excluding the date of such payment):

shall pay to the Administrative Agent, for the account of the Lenders, on each
Incremental Term Loan Repayment Date, a principal amount of the Other Term
Loans (as adjusted from time to time pursuant to Sections 2.11(c), 2.12
and 2.13(e)) equal to the amount set forth for such date in the applicable
Incremental Term Loan Assumption Agreement, together in each case with accrued
and unpaid interest on the principal amount to be paid to but excluding the

(c)                                  In
the event and on each occasion that any Term Loan Commitment (other than any
Incremental Term Loan Commitment) shall be reduced or shall expire or terminate
other than as a result of the making of a Term Loan, the installments payable
on each Repayment Date shall be reduced pro rata by an aggregate amount equal
to the amount of such reduction, expiration or termination.

(d)                                 To
the extent not previously paid, all Term Loans shall be due and payable on the
Term Loan Maturity Date and all Incremental Term Loans shall be due and payable
on the applicable Incremental Term Loan Maturity Date, together in each case
with accrued and unpaid interest on the principal amount to be paid to but
excluding the date of payment.

(e)                                  Notwithstanding anything to the contrary in
this Section 2.11, if any Senior Subordinated Notes are outstanding on February
1, 2012, then, on February 1, 2012, all outstanding Term Loans shall
automatically become due and payable. 
Any Senior Subordinated Notes
that have been defeased in accordance with the Senior Subordinated Note
Indenture shall be deemed to be no longer outstanding for the purposes of this
paragraph.

(f)                                    All
repayments pursuant to this Section 2.11 shall be subject to Section 2.15, but
shall otherwise be without premium or penalty.

SECTION
2.12.  Optional Prepayments.  (a) 
The Borrower shall have the right at any time and from time to time to
prepay any Borrowing, in whole or in part, upon at least three Business Days’
prior written or fax notice (or telephonic notice promptly confirmed by written
notice) in the case of Eurocurrency Loans, or written or fax notice (or
telephonic notice promptly confirmed by written notice) at least one Business
Day prior to the date of prepayment in the case of ABR Loans, to the
Administrative Agent before 12:00 (noon), Local Time; provided, however,
that (i) each partial prepayment of Loans denominated in Dollars shall be in an
amount that is an integral multiple of $100,000 and not less than $500,000 and
(ii) each partial prepayment of Loans denominated in Euros shall be in an
amount that is an integral multiple of €100,000 and not less than €500,000.

(b)                                 Optional
prepayments of outstanding Term Loans under this Agreement shall be allocated
between Euro Term Loans and all other Term Loans as directed by Polypore (with
any amount allocated to such other Term Loans being applied ratably thereto),
and shall be applied to the installments thereof as directed by Polypore.

(c)                                  Each
notice of prepayment shall specify the prepayment date and the principal amount
and currency denomination of each Borrowing (or portion thereof) to be prepaid,
shall be irrevocable and shall commit the Borrower to prepay such Borrowing by
the amount stated therein on the date stated therein.  All prepayments under this Section 2.12 shall
be subject to Section 2.15 but otherwise without premium or penalty.  All prepayments under this Section 2.12 shall
be accompanied by accrued and unpaid interest on the principal amount to be
prepaid to but excluding the date of payment; provided, however,
that in the case of a prepayment of an ABR Revolving Loan or a Swingline Loan
that is not made in connection with a termination of the Revolving Credit
Commitments, the accrued and unpaid interest on the principal amount prepaid
shall be payable on the next scheduled Interest Payment Date with respect to
such ABR Revolving Loan or Swingline Loan.

SECTION 2.13.  Mandatory Prepayments.  (a)  In
the event of any termination of all the Revolving Credit Commitments, Polypore
shall, on the date of such termination, repay or prepay all its outstanding
Revolving Credit Borrowings and all outstanding Swingline Loans and replace all
outstanding Letters of Credit. If as a result of any partial reduction of the
Revolving Credit Commitments the Aggregate Revolving Credit Exposure would
exceed the Total Revolving Credit Commitment after giving effect thereto, then
Polypore shall, on the date of such reduction, repay or prepay Revolving Credit
Borrowings

 43
 

or Swingline Loans (or a combination thereof) and/or
replace outstanding Letters of Credit in an amount sufficient to eliminate such
excess.

(b)                                 Not
later than the third Business Day following the completion of any Asset Sale or
Recovery Event, the Borrower shall apply 100% of the Net Cash Proceeds received
with respect thereto to prepay outstanding Term Loans in accordance with
Section 2.13(e).

(c)                                  No
later than the earlier of (i) 90 days after the end of each fiscal year of
Polypore, commencing with the fiscal year ending on January 3, 2009, and (ii)
the date on which the financial statements with respect to such period are
delivered pursuant to Section 5.4(a), the Borrower shall prepay
outstanding Term Loans in accordance with Section 2.13(e) in an aggregate
principal amount equal to 50% of Excess Cash Flow for the fiscal year then
ended;  provided, however, that
in the event the Total Leverage Ratio at the end of such fiscal year was equal
to or less than 5.00 to 1.00 and greater than 4.00 to 1.00, then such amount
shall be reduced to 25% of such Excess Cash Flow and in the event the Total
Leverage Ratio at the end of such fiscal year was equal to or less than 4.00 to
1.00, no such prepayment shall be required.

(d)                                 In
the event that any Loan Party or any subsidiary of a Loan Party shall receive
Net Cash Proceeds from the issuance or other disposition of Indebtedness for
money borrowed (or similar transaction evidenced by bonds, debentures, notes or
similar instruments) of any Loan Party or any subsidiary of a Loan Party (other
than Indebtedness for money borrowed (or similar transaction evidenced by
bonds, debentures, notes or similar instruments) permitted pursuant to
Section 6.1, except for Indebtedness incurred under clause (xi) of the
definition of “Permitted Indebtedness”, for which a mandatory prepayment shall
be required), the Borrower shall, substantially simultaneously with (and in any
event not later than the third Business Day next following) the receipt of such
Net Cash Proceeds by such Loan Party or such subsidiary, apply an amount equal
to 100% of such Net Cash Proceeds to prepay outstanding Term Loans in
accordance with Section 2.13(e).

(e)                                  Mandatory
prepayments of outstanding Term Loans under this Agreement shall be allocated
between Euro Term Loans and all other Term Loans as directed by Polypore (with
any amount allocated to such other Term Loans being applied ratably thereto),
and shall be applied to the installments thereof as directed by Polypore.

(f)                                    The
Borrower shall deliver to the Administrative Agent, at the time of each
prepayment required under this Section 2.13, (i) a certificate signed by a
Financial Officer of the Borrower setting forth in reasonable detail the
calculation of the amount of such prepayment and (ii) to the extent
practicable, at least three days prior written notice of such prepayment.  Each notice of prepayment shall specify the
prepayment date, the Type of each Loan being prepaid and the principal amount
of each Loan (or portion thereof) to be prepaid.  All prepayments of Borrowings under this
Section 2.13 shall be subject to Section 2.15, but shall otherwise be without
premium or penalty.

SECTION 2.14.  Reserve Requirements; Change in Circumstances.  (a) 
Notwithstanding any other provision of this Agreement, if any Change in
Law shall impose, modify or deem applicable any reserve, special deposit or
similar requirement against assets of, deposits with or for the account of or
credit extended by any Lender or the Issuing Bank (except any such reserve
requirement which is reflected in the Eurocurrency Rate) or shall impose on
such Lender or the Issuing Bank or the London interbank market any other
condition affecting this Agreement or Eurocurrency Loans made by such Lender or
any Letter of Credit or participation therein, and the result of any of the
foregoing shall be to increase the cost to such Lender or the Issuing Bank of
making or maintaining any Eurocurrency Loan or increase the cost to any Lender
of issuing or maintaining any Letter of Credit or purchasing or maintaining a
participation therein or to reduce the amount of any sum received or receivable
by such Lender or the Issuing Bank

 44
 

hereunder (whether of principal, interest or
otherwise), in each case, by an amount deemed by such Lender or the Issuing
Bank to be material, then the Borrower will pay to such Lender or the Issuing
Bank, as the case may be, upon demand such additional amount or amounts as will
compensate such Lender or the Issuing Bank, as the case may be, for such
additional costs incurred or reduction suffered.

(b)                                 If
any Lender or the Issuing Bank shall have determined that any Change in Law
regarding capital adequacy has or would have the effect of reducing the rate of
return on such Lender’s or the Issuing Bank’s capital or on the capital of such
Lender’s or the Issuing Bank’s holding company, if any, as a consequence of
this Agreement or the Loans made or participations in Letters of Credit purchased
by such Lender pursuant hereto or the Letters of Credit issued by the Issuing
Bank pursuant hereto to a level below that which such Lender or the Issuing
Bank or such Lender’s or the Issuing Bank’s holding company could have achieved
but for such Change in Law (taking into consideration such Lender’s or the
Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s
holding company with respect to capital adequacy) by an amount deemed by such
Lender or the Issuing Bank to be material, then from time to time the Borrower
shall pay to such Lender or the Issuing Bank, as the case may be, such
additional amount or amounts as will compensate such Lender or the Issuing Bank
or such Lender’s or the Issuing Bank’s holding company for any such reduction
suffered.

(c)                                  A
certificate of a Lender or the Issuing Bank setting forth the amount or amounts
necessary to compensate such Lender or the Issuing Bank or its holding company,
as applicable, as specified in paragraph (a) or (b) above shall be delivered to
the Borrower and shall be conclusive absent manifest error.  The Borrower shall pay such Lender or the
Issuing Bank the amount shown as due on any such certificate delivered by it
within 10 days after its receipt of the same.

(d)                                 Failure
or delay on the part of any Lender or the Issuing Bank to demand compensation
for any increased costs or reduction in amounts received or receivable or
reduction in return on capital shall not constitute a waiver of such Lender’s
or the Issuing Bank’s right to demand such compensation; provided, that the Borrower shall not be under any obligation to
compensate any Lender or the Issuing Bank under paragraph (a) or (b) above with
respect to increased costs or reductions with respect to any period prior to the
date that is 180 days prior to such request if such Lender or the Issuing Bank
knew or could reasonably have been expected to know of the circumstances giving
rise to such increased costs or reductions and of the fact that such
circumstances would result in a claim for increased compensation by reason of
such increased costs or reductions; provided,  further, that the foregoing
limitation shall not apply to any increased costs or reductions arising out of
the retroactive application of any Change in Law within such 180-day
period.  The protection of this Section
shall be available to each Lender and the Issuing Bank regardless of any
possible contention of the invalidity or inapplicability of the Change in Law
that shall have occurred or been imposed.

SECTION 2.15.  Indemnity.  The Borrower shall indemnify each Lender
against any loss or expense that such Lender may sustain or incur as a
consequence of (a) any event, other than a default by such Lender in the
performance of its obligations hereunder, which results in (i) such Lender
receiving or being deemed to receive any amount on account of the principal of
any Eurocurrency Loan prior to the end of the Interest Period in effect
therefor, (ii) the conversion of any Eurocurrency Loan to an ABR Loan, or the conversion
of the Interest Period with respect to any Eurocurrency Loan, in each case
other than on the last day of the Interest Period in effect therefor, or (iii)
any Eurocurrency Loan to be made by such Lender (including any Eurocurrency
Loan to be made pursuant to a conversion or continuation under Section 2.10)
not being made after notice of such Loan shall have been given by the Borrower
hereunder (any of the events referred to in this clause (a) being called a “Breakage
Event”) or (b) any default in the making of any payment or prepayment
required to be made hereunder.  In the
case of any Breakage Event, such loss shall include an amount equal to the
excess, as reasonably determined by such Lender, of (i) its cost of obtaining
funds for the Eurocurrency Loan that is the subject of such Breakage Event for
the period from

 45
 

the date of such Breakage Event to the last day of the
Interest Period in effect (or that would have been in effect) for such Loan
over (ii) the amount of interest likely to be realized by such Lender in
redeploying the funds released or not utilized by reason of such Breakage Event
for such period, but such loss shall not, in any event, include any lost profit
or loss of applicable margin.  A certificate
of any Lender setting forth any amount or amounts which such Lender is entitled
to receive pursuant to this Section 2.15 shall be delivered to the Borrower and
shall be conclusive absent manifest error.

SECTION
2.16.  Pro Rata Treatment.  Each Borrowing, each payment or prepayment of
principal of any Borrowing, each payment of interest on the Loans, each payment
of the Commitment Fees or the L/C Participation Fees, each reduction of the
Term Loan Commitments or the Revolving Credit Commitments and each conversion
of any Borrowing to or continuation of any Borrowing as a Borrowing of any Type
shall be allocated pro rata among the Lenders in accordance with their
respective applicable Commitments (or, if such Commitments shall have expired
or been terminated, in accordance with the respective principal amounts of
their outstanding Loans or participations in L/C Disbursements, as
applicable).  Each Lender agrees that in
computing such Lender’s portion of any Borrowing to be made hereunder, the
Administrative Agent may, in its discretion, round each Lender’s percentage of
such Borrowing to the next higher or lower whole dollar amount.

SECTION
2.17.  Sharing of Setoffs.  Each Lender agrees that if it shall, through
the exercise of a right of banker’s lien, setoff or counterclaim against the
Borrower or any other Loan Party, or pursuant to a secured claim under Section
506 of Title 11 of the United States Code or other security or interest arising
from, or in lieu of, such secured claim, received by such Lender under any
applicable bankruptcy, insolvency or other similar law or otherwise, or by any
other means, obtain payment (voluntary or involuntary) in respect of any Loan
or L/C Disbursement as a result of which the unpaid portion of its Loans and
participations in L/C Disbursements shall be proportionately less than the
unpaid portion of the Loans and participations in L/C Disbursements of any
other Lender, it shall be deemed simultaneously to have purchased from such
other Lender at face value, and shall promptly pay to such other Lender the purchase
price for, a participation in the Loans and L/C Exposure of such other Lender,
so that the aggregate unpaid amount of the Loans and L/C Exposure and
participations in Loans and L/C Exposure held by each Lender shall be in the
same proportion to the aggregate unpaid amount of all Loans and L/C Exposure
then outstanding as the amount of its Loans and L/C Exposure prior to such
exercise of banker’s lien, setoff or counterclaim or other event was to the
amount of all Loans and L/C Exposure outstanding prior to such exercise of
banker’s lien, setoff or counterclaim or other event; provided, however,
that if any such purchase or purchases or adjustments shall be made pursuant to
this Section 2.17 and the payment giving rise thereto shall thereafter be
recovered, such purchase or purchases or adjustments shall be rescinded to the
extent of such recovery and the purchase price or prices or adjustment restored
without interest.  Polypore, Daramic
Holding and Holdings expressly consent to the foregoing arrangements and agree
that any Lender holding a participation in a Loan or L/C Disbursement deemed to
have been so purchased may exercise any and all rights of banker’s lien, setoff
or counterclaim with respect to any and all moneys owing by Polypore, Daramic
Holding and Holdings to such Lender by reason thereof as fully as if such
Lender had made a Loan directly to the Borrower in the amount of such
participation.

SECTION 2.18.  Payments.  (a) 
The Borrower shall make each payment (including principal of or interest
on any Borrowing or any L/C Disbursement or any Fees or other amounts)
hereunder and under any other Loan Document not later than 12:00 (noon), Local
Time, on the date when due in Dollars or Euros, as applicable, and in
immediately available funds, without setoff, defense or counterclaim.  Each such payment (other than (i) Issuing
Bank Fees, which shall be paid directly to the Issuing Bank, and (ii) principal
of and interest on Swingline Loans, which shall be paid directly to the
Swingline Lender except as otherwise provided in Section 2.20(e)) shall be made
to the Administrative Agent at the Funding Office, or at such other location as
the Administrative Agent shall notify the Borrower from time to time

 46
 

in accordance with Section 9.1.  The Administrative Agent shall distribute any
such payments received by it for the account of any other Person to the
appropriate recipient promptly following receipt thereof.

(b)                                 Except
as otherwise expressly provided herein, whenever any payment (including
principal of or interest on any Borrowing or any Fees or other amounts)
hereunder or under any other Loan Document shall become due, or otherwise would
occur, on a day that is not a Business Day, such payment may be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of interest or Fees, if applicable.

SECTION
2.19.  Taxes.  (a) 
Any and all payments by or on account of any obligation of the Borrower
or any Loan Party hereunder or under any other Loan Document shall be made free
and clear of and without deduction for any Indemnified Taxes or Other Taxes; provided,
that if the Borrower or any Loan Party shall be required to deduct any
Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable
shall be increased as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section)
the Administrative Agent or such Lender (as the case may be) receives an amount
equal to the sum it would have received had no such deductions been made, (ii)
the Borrower or such Loan Party shall make such deductions and (iii) the
Borrower or such Loan Party shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

(b)                                 In
addition, the Borrower shall pay any Other Taxes to the relevant Governmental
Authority in accordance with applicable law.

(c)                                  The
Borrower shall indemnify the Administrative Agent and each Lender, within 10
days after written demand therefor, for the full amount of any Indemnified
Taxes or Other Taxes paid by the Administrative Agent or such Lender, as the
case may be, on or with respect to any payment by or on account of any
obligation of the Borrower or any Loan Party hereunder or under any other Loan
Document (including Indemnified Taxes or Other Taxes imposed or asserted on or
attributable to amounts payable under this Section) and any penalties, interest
and reasonable expenses arising therefrom or with respect thereto (other than
penalties or interest attributable to (i) a failure or delay by the
Administrative Agent or such Lender, as applicable, in making such written
demand to the Borrower or (ii) the gross negligence or willful misconduct of
the Administrative Agent or such Lender, as applicable), whether or not such
Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted
by the relevant Governmental Authority. 
A certificate as to the amount of such payment or liability delivered to
the Borrower by a Lender, or by the Administrative Agent on its behalf or on
behalf of a Lender, shall be conclusive absent manifest error.

(d)                                 As
soon as practicable after any payment of Indemnified Taxes or Other Taxes by
the Borrower or any other Loan Party to a Governmental Authority, the Borrower
shall deliver to the Administrative Agent the original or a certified copy of a
receipt issued by such Governmental Authority evidencing such payment, a copy
of the return reporting such payment or other evidence of such payment
reasonably satisfactory to the Administrative Agent.

(e)                                  Any
Foreign Lender that is entitled to an exemption from or reduction of
withholding tax under the law of the jurisdiction in which the Borrower is
located, or any treaty to which such jurisdiction is a party, with respect to
payments under this Agreement shall deliver to the Borrower (with a copy to the
Administrative Agent), at the time or times prescribed by applicable law, such
properly completed and executed documentation prescribed by applicable law or
reasonably requested by the Borrower as will permit such payments to be made
without withholding or at a reduced rate.

 47
 

SECTION
2.20.  Assignment of
Commitments Under Certain Circumstances; Duty to Mitigate.  (a)  In
the event (i) any Lender or the Issuing Bank delivers a certificate requesting
compensation pursuant to Section 2.14, (ii) the Borrower is required to pay any
additional amount to any Lender or the Issuing Bank or any Governmental
Authority on account of any Lender or the Issuing Bank pursuant to Section
2.19, (iii) any Lender becomes a Defaulting Lender or (iv) any Lender refuses
to consent to any amendment, waiver or other modification of any Loan Document
requested by Polypore or Daramic Holding that requires the consent of a greater
percentage of the Lenders than the Required Lenders and such amendment, waiver
or other modification is consented to by the Required Lenders, Polypore or
Daramic Holding may, at its sole expense and effort (including with respect to
the processing and recordation fee referred to in Section 9.4(b)), upon notice
to such Lender or the Issuing Bank and the Administrative Agent, require such
Lender or the Issuing Bank to transfer and assign, without recourse,
representation or warranty, except as to warranty as to its ownership of the
assigned obligations (in accordance with and subject to the restrictions
contained in Section 9.4), all of its interests, rights and obligations under
this Agreement to an assignee that shall assume such assigned obligations and,
with respect to clause (iv) above, shall consent to such requested amendment,
waiver or other modification of any Loan Document (which assignee may be
another Lender, if a Lender accepts such assignment); provided that (x) such
assignment shall not conflict with any law, rule or regulation or order of any
court or other Governmental Authority having jurisdiction, (y) Polypore or
Daramic Holding shall have received the prior written consent of the
Administrative Agent (and, if a Revolving Credit Commitment is being assigned,
of the Issuing Bank and the Swingline Lender), which consent shall not
unreasonably be withheld, and (z) the Borrower or such assignee shall have paid
to the affected Lender or the Issuing Bank in immediately available funds an
amount equal to the sum of the principal of and interest accrued to the date of
such payment on the outstanding Loans or L/C Disbursements of such Lender or
the Issuing Bank plus all Fees and other amounts accrued for the account of
such Lender or the Issuing Bank hereunder (including any amounts under Section
2.14 and Section 2.15); provided, further, that, if prior to
any such transfer and assignment the circumstances or event that resulted in
such Lender’s or the Issuing Bank’s claim for compensation under
Section 2.14 or the amounts paid pursuant to Section 2.19, as the case may
be, cease to cause such Lender or the Issuing Bank to suffer increased costs or
reductions in amounts received or receivable or reduction in return on capital
or cease to result in amounts being payable under Section 2.19, as the case may
be (including as a result of any action taken by such Lender or the Issuing
Bank pursuant to paragraph (b) below), or if such Lender or the Issuing Bank
shall waive its right to claim further compensation under Section 2.14 in
respect of such circumstances or event or shall waive its right to further
payments under Section 2.19 in respect of such circumstances or event or shall
consent to the proposed amendment, waiver, consent or other modification, as
the case may be, then such Lender or the Issuing Bank shall not thereafter be
required to make any such transfer and assignment hereunder.

(b)                                 If
(i) any Lender or the Issuing Bank shall request compensation under
Section 2.14 or (ii) the Borrower is required to pay any additional amount
to any Lender or the Issuing Bank or any Governmental Authority on account of
any Lender or the Issuing Bank, pursuant to Section 2.19, then such Lender
or the Issuing Bank shall use reasonable efforts (which shall not require such
Lender or the Issuing Bank to incur an unreimbursed loss or unreimbursed cost
or expense or otherwise take any action inconsistent with its internal policies
or legal or regulatory restrictions or suffer any disadvantage or burden deemed
by it to be significant) (x) to file any certificate or document reasonably
requested in writing by the Borrower or (y) to assign its rights and delegate
and transfer its obligations hereunder to another of its offices, branches or
Affiliates, if such filing or assignment would reduce its claims for
compensation under Section 2.14 or would reduce amounts payable pursuant to
Section 2.19, as the case may be, in the future.  The Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender or the Issuing Bank in connection
with any such filing or assignment, delegation and transfer.

SECTION 2.21.  Swingline Loans.  (a)  Swingline
Commitment.  Subject to the terms and
conditions and relying upon the representations and warranties herein set
forth, the Swingline Lender agrees to make loans to

 48
 

Polypore at any time and from time to time on and
after the Restatement Effective Date and until the earlier of the Revolving
Credit Maturity Date and the termination of the Revolving Credit Commitments in
accordance with the terms hereof, in an aggregate principal amount at any time
outstanding that will not result in (i) the aggregate principal amount of all
Swingline Loans exceeding $10,000,000 in the aggregate or (ii) the Aggregate
Revolving Credit Exposure, after giving effect to any Swingline Loan, exceeding
the Total Revolving Credit Commitment. 
Each Swingline Loan shall be in a principal amount that is an integral
multiple of $100,000 and not less than $100,000.  The Swingline Commitment may be terminated or
reduced from time to time as provided herein. 
Within the foregoing limits, Polypore may borrow, pay or prepay and
reborrow Swingline Loans hereunder, subject to the terms, conditions and limitations
set forth herein.

(b)                                 Swingline Loan Borrowing Procedure.
Polypore shall notify the Swingline Lender by fax, or by telephone (confirmed
by fax), not later than 12:00 (noon), New York City time, on the day of a
proposed Swingline Loan.  Such notice
shall be delivered on a Business Day, shall be irrevocable and shall refer to
this Agreement and shall specify the requested date (which shall be a Business
Day) and amount of such Swingline Loan and the wire transfer instructions for
the account of Polypore to which the proceeds of such Swingline Loan should be
transferred. The Swingline Lender shall promptly make each Swingline Loan by
wire transfer to the account specified by Polypore in such request.

(c)                                  Prepayment.  Polypore shall have the right at any time and
from time to time to prepay any Swingline Loan, in whole or in part, upon
giving written or fax notice (or telephonic notice promptly confirmed by
written notice) to the Swingline Lender and to the Administrative Agent before
12:00 (noon), New York City time on the date of prepayment at the Swingline
Lender’s address for notices specified in Section 9.1.

(d)                                 Interest.  Each Swingline Loan shall be an ABR Loan and,
subject to the provisions of Section 2.7, shall bear interest at the rate
provided for the ABR Revolving Loans as provided in Section 2.6(a).

(e)                                  Participations.  The Swingline Lender may by written notice
given to the Administrative Agent not later than 11:00 a.m., New York City
time, on any Business Day require the Revolving Credit Lenders to acquire
participations on such Business Day in all or a portion of the Swingline Loans
outstanding.  Such notice shall specify
the aggregate amount of Swingline Loans in which the Revolving Credit Lenders
will participate.  The Administrative
Agent will, promptly upon receipt of such notice, give notice to each Revolving
Credit Lender, specifying in such notice such Lender’s Pro Rata Percentage of
such Swingline Loan or Loans.  In
furtherance of the foregoing, each Revolving Credit Lender hereby absolutely
and unconditionally agrees, upon receipt of notice as provided above, to pay to
the Administrative Agent, for the account of the Swingline Lender, such
Revolving Credit Lender’s Pro Rata Percentage of such Swingline Loan or
Loans.  Each Revolving Credit Lender
acknowledges and agrees that its obligation to acquire participations in
Swingline Loans pursuant to this paragraph is absolute and unconditional and
shall not be affected by any circumstance whatsoever, including the occurrence
and continuance of a Default or an Event of Default, and that each such payment
shall be made without any offset, abatement, withholding or reduction
whatsoever.  Each Revolving Credit Lender
shall comply with its obligation under this paragraph by wire transfer of
immediately available funds, in the same manner as provided in Section 2.2(c)
with respect to Loans made by such Lender (and Section 2.2(c) shall apply, mutatis mutandis, to the payment obligations of the Lenders)
and the Administrative Agent shall promptly pay to the Swingline Lender the
amounts so received by it from the Lenders. 
The Administrative Agent shall notify Polypore of any participations in
any Swingline Loan acquired pursuant to this paragraph and thereafter payments
in respect of such Swingline Loan shall be made to the Administrative Agent and
not to the Swingline Lender.  Any amounts
received by the Swingline Lender from Polypore (or other party on behalf of
Polypore) in respect of a Swingline Loan after receipt by the Swingline Lender
of the

 49
 

proceeds of a
sale of participations therein shall be promptly remitted to the Administrative
Agent; any such amounts received by the Administrative Agent shall be promptly
remitted by the Administrative Agent to the Lenders that shall have made their
payments pursuant to this paragraph and to the Swingline Lender, as their
interests may appear. The purchase of participations in a Swingline Loan
pursuant to this paragraph shall not relieve Polypore (or other party liable
for obligations of Polypore) of any default in the payment thereof.

SECTION
2.22.  Letters of Credit.  (a)  General.  Polypore may request the issuance of a Letter
of Credit denominated in Dollars or in an Alternative Currency for its own
account or for the account of any Subsidiary, in a form reasonably acceptable to
the Administrative Agent and the Issuing Bank, at any time and from time to
time while the Revolving Credit Commitments remain in effect.  This Section shall not be construed to impose
an obligation upon the Issuing Bank to issue any Letter of Credit that is
inconsistent with the terms and conditions of this Agreement.

(b)                                 Notice of Issuance, Amendment, Renewal,
Extension; Certain Conditions. 
In order to request the issuance of a Letter of Credit (or to amend,
renew or extend an existing Letter of Credit), Polypore shall hand deliver or
fax to the Issuing Bank and the Administrative Agent (reasonably in advance of
the requested date of issuance, amendment, renewal or extension) a notice
requesting the issuance of a Letter of Credit, or identifying the Letter of
Credit to be amended, renewed or extended, the date of issuance, amendment,
renewal or extension, the date on which such Letter of Credit is to expire
(which shall comply with paragraph (c) below), whether such Letter of Credit
shall be issued in Dollars or an Alternative Currency, the amount of such
Letter of Credit, the name and address of the beneficiary thereof and such
other information as shall be necessary to prepare such Letter of Credit. The
Issuing Bank shall promptly (i) notify the Administrative Agent in writing of
the amount and expiry date of each Letter of Credit issued by it and (ii)
provide a copy of each such Letter of Credit (and any amendments, renewals or
extensions thereof) to the Administrative Agent.  A Letter of Credit shall be issued, amended,
renewed or extended only if, and upon issuance, amendment, renewal or extension
of each Letter of Credit Polypore shall be deemed to represent and warrant
that, after giving effect to such issuance, amendment, renewal or extension (i)
the L/C Exposure shall not exceed $50,000,000, (ii) the Aggregate Alternative
Currency Exposure shall not exceed $50,000,000 and (iii) the Aggregate
Revolving Credit Exposure shall not exceed the Total Revolving Credit
Commitment.

(c)                                  Expiration Date.  Each Letter of Credit shall expire at the
close of business on the earlier of the date one year after the date of the
issuance of such Letter of Credit and the date that is five Business Days prior
to the Revolving Credit Maturity Date, unless such Letter of Credit expires by
its terms on an earlier date; provided,
that a Letter of Credit may, upon the request of Polypore, include a provision
whereby such Letter of Credit shall be renewed automatically for additional
consecutive periods of 12 months or less (but not beyond the date that is five
Business Days prior to the Revolving Credit Maturity Date) unless the Issuing
Bank notifies the beneficiary thereof at least 30 days prior to the
then-applicable expiration date that such Letter of Credit will not be renewed.

(d)                                 Participations.  By the issuance of a Letter of Credit and
without any further action on the part of the Issuing Bank or the Lenders, the
Issuing Bank hereby grants to each Revolving Credit Lender, and each such
Lender hereby acquires from the Issuing Bank, a participation in such Letter of
Credit equal to such Lender’s Pro Rata Percentage of the aggregate amount
available to be drawn under such Letter of Credit, effective upon the issuance
of such Letter of Credit.  In
consideration and in furtherance of the foregoing, each Revolving Credit Lender
hereby absolutely and unconditionally agrees to pay to the Administrative
Agent, for the account of the Issuing Bank, such Lender’s Pro Rata Percentage
of each L/C Disbursement made by the Issuing Bank and not reimbursed by
Polypore (or, if applicable, another party pursuant to its obligations under
any other Loan Document) forthwith on the date due as provided in
Section 2.2(f).  Each Revolving
Credit Lender acknowledges and agrees that its obligation to acquire

 50
 

participations
pursuant to this paragraph in respect of Letters of Credit is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including the occurrence and continuance of a Default or an Event of Default,
and that each such payment shall be made without any offset, abatement,
withholding or reduction whatsoever.

(e)                                  Reimbursement.  If the Issuing Bank shall make any L/C
Disbursement in respect of a Letter of Credit, Polypore shall pay to the
Administrative Agent (or directly to the Issuing Bank, with concurrent notice
to the Administrative Agent) an amount (in the currency in which the Letter of
Credit was denominated) equal to such L/C Disbursement not later than two hours
after Polypore shall have received notice from the Issuing Bank that payment of
such draft will be made, or, if Polypore shall have received such notice later
than 10:00 a.m., Local Time, on any Business Day, not later than 10:00 a.m.,
Local Time, on the immediately following Business Day.

(f)                                    Obligations Absolute.  Polypore’s obligations to reimburse L/C
Disbursements as provided in paragraph (e) above shall be absolute,
unconditional and irrevocable, and shall be performed strictly in accordance
with the terms of this Agreement, under any and all circumstances whatsoever,
and irrespective of:

(i)  
any lack of validity or enforceability of any Letter of Credit or any Loan
Document, or any term or provision therein;

(ii)  
any amendment or waiver of or any consent to departure from all or any of the
provisions of any Letter of Credit or any Loan Document;

(iii)  
the existence of any claim, setoff, defense or other right that Polypore, any
other party guaranteeing, or otherwise obligated with, Polypore, any Subsidiary
or other Affiliate thereof or any other Person may at any time have against the
beneficiary under any Letter of Credit, the Issuing Bank, the Administrative
Agent or any Lender or any other Person, whether in connection with this
Agreement, any other Loan Document or any other related or unrelated agreement
or transaction;

(iv)  
any draft or other document presented under a Letter of Credit proving to be
forged, fraudulent, invalid or insufficient in any respect or any statement
therein being untrue or inaccurate in any respect;

(v)  
payment by the Issuing Bank under a Letter of Credit against presentation of a
draft or other document that does not comply with the terms of such Letter of
Credit; and

(vi)  
any other act or omission to act or delay of any kind of the Issuing Bank, the
Lenders, the Administrative Agent or any other Person or any other event or
circumstance whatsoever, whether or not similar to any of the foregoing, that
might, but for the provisions of this Section, constitute a legal or equitable
discharge of Polypore’s obligations hereunder.

Without limiting
the generality of the foregoing, it is expressly understood and agreed that the
absolute and unconditional obligation of Polypore hereunder to reimburse L/C
Disbursements will not be excused by the gross negligence or willful misconduct
of the Issuing Bank.  However, the
foregoing shall not be construed to excuse the Issuing Bank from liability to
Polypore to the extent of any direct damages (as opposed to consequential
damages, claims in respect of which are hereby waived by Polypore to the extent
permitted by applicable law) suffered by Polypore that are caused by the
Issuing Bank’s gross negligence or willful misconduct in determining whether
drafts and other documents presented under a Letter of Credit comply with the
terms thereof; it is understood that the Issuing Bank may accept

 51
 

documents that appear on their face to be in order,
without responsibility for further investigation, regardless of any notice or
information to the contrary and, in making any payment under any Letter of
Credit (i) the Issuing Bank’s exclusive reliance on the documents presented to
it under such Letter of Credit as to any and all matters set forth therein,
including reliance on the amount of any draft presented under such Letter of
Credit, whether or not the amount due to the beneficiary thereunder equals the
amount of such draft and whether or not any document presented pursuant to such
Letter of Credit proves to be insufficient in any respect, if such document on
its face appears to be in order, and whether or not any other statement or any
other document presented pursuant to such Letter of Credit proves to be forged
or invalid or any statement therein proves to be inaccurate or untrue in any
respect whatsoever and (ii) any noncompliance in any immaterial respect of the
documents presented under such Letter of Credit with the terms thereof shall,
in each case, be deemed not to constitute willful misconduct or gross
negligence of the Issuing Bank.

(g)                                 Disbursement Procedures.  The Issuing Bank shall, promptly following
its receipt thereof, examine all documents purporting to represent a demand for
payment under a Letter of Credit.  The
Issuing Bank shall as promptly as possible give telephonic notification,
confirmed by fax, to the Administrative Agent and Polypore of such demand for
payment and whether the Issuing Bank has made or will make an L/C Disbursement
thereunder; provided,
that any failure to give or delay in giving such notice shall not relieve
Polypore of its obligation to reimburse the Issuing Bank and the Revolving
Credit Lenders with respect to any such L/C Disbursement.  The Administrative Agent shall promptly give
each Revolving Credit Lender notice thereof.

(h)                                 Interim Interest.  If the Issuing Bank shall make any L/C
Disbursement in respect of a Letter of Credit, then, unless Polypore shall
reimburse such L/C Disbursement in full on such date, the unpaid amount thereof
shall bear interest for the account of the Issuing Bank, for each day from and
including the date of such L/C Disbursement, to but excluding the earlier of
the date of payment by Polypore or the date on which interest shall commence to
accrue thereon as provided in Section 2.2(f), at the rate per annum that would
apply to such amount if such amount were an ABR Revolving Loan.

(i)                                     Resignation or Removal of the Issuing Bank.  The Issuing Bank may resign at any time by
giving 30 days’ prior written notice to the Administrative Agent, the Lenders
and Polypore, and may be removed at any time by Polypore by notice to the
Issuing Bank, the Administrative Agent and the Lenders.  Subject to the next succeeding paragraph,
upon the acceptance of any appointment as the Issuing Bank hereunder by a
Lender that shall agree to serve as successor Issuing Bank, such successor
shall succeed to and become vested with all the interests, rights and
obligations of the retiring Issuing Bank and the retiring Issuing Bank shall be
discharged from its obligations to issue additional Letters of Credit
hereunder.  At the time such removal or
resignation shall become effective, Polypore shall pay all accrued and unpaid
fees pursuant to Section 2.5(c)(ii).  The
acceptance of any appointment as the Issuing Bank hereunder by a successor
Lender shall be evidenced by an agreement entered into by such successor, in a
form satisfactory to Polypore and the Administrative Agent, and, from and after
the effective date of such agreement, (i) such successor Lender shall have all
the rights and obligations of the previous Issuing Bank under this Agreement
and the other Loan Documents and (ii) references herein and in the other Loan
Documents to the term “Issuing Bank” shall be deemed to refer to such successor
or to any previous Issuing Bank, or to such successor and all previous Issuing
Banks, as the context shall require. 
After the resignation or removal of the Issuing Bank hereunder, the
retiring Issuing Bank shall remain a party hereto and shall continue to have
all the rights and obligations of an Issuing Bank under this Agreement and the
other Loan Documents with respect to Letters of Credit issued by it prior to
such resignation or removal, but shall not be required to issue additional
Letters of Credit.

(j)                                     Cash Collateralization.  If any Event of Default shall occur and be continuing,
Polypore shall, on the Business Day it receives notice from the Administrative
Agent or the Required Lenders (or,

 52
 

if the
maturity of the Loans has been accelerated, Revolving Credit Lenders holding
participations in outstanding Letters of Credit representing greater than 50%
of the aggregate undrawn amount of all outstanding Letters of Credit) thereof
and of the amount to be deposited, deposit in an account with the
Administrative Agent, for the benefit of the Revolving Credit Lenders, an amount
in cash equal to the L/C Exposure as of such date; provided, however,
that the obligation to deposit such cash shall become effective immediately,
and such deposit shall become immediately due and payable, without demand or
other notice of any kind, upon the occurrence of any Event of Default with
respect to Polypore described in clause (g) or (h) of Article VII.  Such deposit shall be held by the
Administrative Agent as collateral for the payment and performance of the
Obligations.  The Administrative Agent
shall have exclusive dominion and control, including the exclusive right of
withdrawal, over such account.  Other
than any interest earned on the investment of such deposits in Permitted
Investments, which investments shall be made at the option and sole discretion
of the Administrative Agent, such deposits shall not bear interest.  Interest or profits, if any, on such
investments shall accumulate in such account. 
Moneys in such account shall (i) automatically be applied by the
Administrative Agent to reimburse the Issuing Bank for L/C Disbursements for
which it has not been reimbursed, (ii) be held for the satisfaction of the
reimbursement obligations of Polypore for the L/C Exposure at such time and
(iii) if the maturity of the Loans has been accelerated (but subject to the
consent of Revolving Credit Lenders holding participations in outstanding
Letters of Credit representing greater than 50% of the aggregate undrawn amount
of all outstanding Letters of Credit), be applied to satisfy the Obligations.  If Polypore is required to provide an amount
of cash collateral hereunder as a result of the occurrence of an Event of
Default, such amount (to the extent not applied as aforesaid) shall be returned
to Polypore within three Business Days after all Events of Default have been
cured or waived.

(k)                                  Additional Issuing Banks.  Polypore may, at any time and from time to
time with the consent of the Administrative Agent (which consent shall not be
unreasonably withheld) and such Lender, designate one or more additional
Lenders to act as an Issuing Bank under the terms of the Agreement.  Any Lender designated as an Issuing Bank
pursuant to this paragraph (k) shall be deemed to be an “Issuing Bank” (in
addition to being a Lender) in respect of Letters of Credit issued or to be
issued by such Lender, and, with respect to such Letters of Credit, such term
shall thereafter apply to the other Issuing Bank and such Lender.

SECTION
2.23.  Increase in Term Loan
Commitments.  (a)  Polypore may, by written notice to the Administrative
Agent from time to time, request Incremental Term Loan Commitments in an amount
not to exceed the Incremental Term Loan Amount from one or more Incremental
Term Lenders (which may include any existing Lender) willing to provide such
Incremental Term Loans in their own discretion; provided, that each
Incremental Term Lender, if not already a Lender hereunder, shall be subject to
the approval of the Administrative Agent (which approval shall not be
unreasonably withheld).  Such notice
shall set forth (i) the amount of the Incremental Term Loan Commitments
being requested (which shall be in minimum increments of $1,000,000 and a
minimum amount of $25,000,000 or equal to the remaining Incremental Term Loan
Amount), (ii) the date on which such Incremental Term Loan Commitments are
requested to become effective (which shall not be less than 10 Business Days
after the date of such notice) and (iii) whether such Incremental Term
Loan Commitments are to be Term Loan Commitments or commitments to make term
loans with terms different from the Term Loans (“Other Term Loans”).

(b)                                 Polypore
and each Incremental Term Lender shall execute and deliver to the
Administrative Agent an Incremental Term Loan Assumption Agreement and such
other documentation as the Administrative Agent shall reasonably specify to
evidence the Incremental Term Loan Commitment of such Incremental Term
Lender.  Each Incremental Term Loan
Assumption Agreement shall specify the terms of the Incremental Term Loans to
be made thereunder; provided,
that, without the prior written consent of the Required Lenders, (i) the
final maturity date of any Other Term Loans

 53
 

shall be no
earlier than the Term Loan Maturity Date, (ii) the average life to
maturity of any Other Term Loans shall be no shorter than the average life to
maturity of the Term Loans, (iii) any Other Term Loans shall be denominated in
Dollars and (iv) after giving pro  forma effect to the incurrence
thereof and any substantially concurrent use of proceeds thereof, the Senior
Leverage Ratio determined as of the last day of the most recent fiscal quarter
for which financial statements are available shall not exceed (x) 3.25 to 1.00
for any such fiscal quarter ending on or prior to June 30, 2008 or (y) 3.00 to
1.00 for any such fiscal quarter ending thereafter.  The Administrative Agent shall promptly
notify each Lender as to the effectiveness of each Incremental Term Loan
Assumption Agreement.  Each of the parties
hereto hereby agrees that, upon the effectiveness of any Incremental Term Loan
Assumption Agreement, this Agreement shall be amended to the extent (but only
to the extent) necessary to reflect the existence and terms of the Incremental
Term Loan Commitment evidenced thereby as provided for in Section 9.8(b).  Any such deemed amendment may be memorialized
in writing by the Administrative Agent with Polypore’s consent (not to be
unreasonably withheld) and furnished to the other parties hereto.

(c)                                  Notwithstanding
the foregoing, no Incremental Term Loan Commitment shall become effective under
this Section 2.23 unless (i) on the date of such effectiveness, the conditions
set forth in paragraphs (b) and (c) of Section 4.1 shall be satisfied and the
Administrative Agent shall have received a certificate to that effect dated
such date and executed by a Financial Officer of Polypore and (ii) the
Administrative Agent shall have received (with sufficient copies for each of
the Incremental Term Lenders) legal opinions, board resolutions and other
closing certificates and documentation consistent with those delivered on the
Restatement Effective Date under Section 4.2.

(d)                                 Each
of the parties hereto hereby agrees that the Administrative Agent may take any
and all action as may be reasonably necessary to ensure that all Incremental
Term Loans (other than Other Term Loans), when originally made, are included in
each Borrowing of outstanding Term Loans on a pro rata basis, and Polypore
agrees that Section 2.15 shall apply to any conversion of Eurocurrency
Term Loans to ABR Term Loans reasonably required by the Administrative Agent to
effect the foregoing.  In addition, to
the extent any Incremental Term Loans are not Other Term Loans, the scheduled
amortization payments under Sections 2.11(a) required to be made after the
making of such Incremental Term Loans shall be ratably increased by the
aggregate principal amount of such Incremental Term Loans.

ARTICLE
III

Representations and Warranties

Each of Holdings and Polypore represents and warrants
to the Administrative Agent, the Issuing Bank and each of the Lenders that:

SECTION
3.1.  Organization; Powers.  Each Group Member (a) is duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
organization, (b) has all requisite power and authority to own its property
and assets and to carry on its business as now conducted and as proposed to be
conducted, (c) is qualified to do business in, and is in good standing in,

Adverse Effect, and (d) has the power and authority to execute, deliver
and perform its obligations under each of the Loan Documents and each other
agreement or instrument contemplated hereby or thereby to which it is or will
be a party and, in the case of the Borrower, to borrow hereunder.

SECTION 3.2.  Authorization.  The Transactions (a) have been duly
authorized by all requisite corporate and, if required, stockholder action and
(b) will not (i) violate (A) any provision of law, statute, rule
or regulation, or of the certificate or articles of incorporation or other
constitutive documents or by-laws of any Group Member, (B) any order of
any Governmental Authority or (C) any provision of any indenture, material
agreement or other material instrument to which any Group Member is a party or
by which any

 54
 

of them or any of their property is or may be bound,
(ii) except as set forth on Schedule 3.2, be in conflict with, result in a
breach of or constitute (alone or with notice or lapse of time or both) a
default under, or give rise to any right to accelerate or to require the
prepayment, repurchase or redemption of any obligation under any such
indenture, material agreement or other material instrument or (iii) result
in the creation or imposition of any Lien upon or with respect to any property
or assets now owned or hereafter acquired by any Group Member (other than any
Lien created hereunder or under the Security Documents).

SECTION
3.3.  Enforceability.  This Agreement has been duly executed and
delivered by Holdings, Polypore and Daramic Holding and constitutes, and each
other Loan Document when executed and delivered by each Loan Party party
thereto will constitute, a legal, valid and binding obligation of such Loan
Party enforceable against such Loan Party in accordance with its terms.

SECTION
3.4.  Governmental Approvals.  No action, consent or approval of,
registration or filing with or any other action by any Governmental Authority
is or will be required in connection with the Transactions, except for
(a) the filing of Uniform Commercial Code financing statements and filings
with the United States Patent and Trademark Office and the United States
Copyright Office, (b) recordation of any Mortgages, (c) such as have been
made or obtained and are in full force and effect or which are not material to
the consummation of the Transactions and (d) those approvals, consents,
exemptions, authorizations or other actions, notices or filings, the failure of
which to obtain or make could not reasonably be expected to have a Material
Adverse Effect.

SECTION
3.5.  Financial Statements.  (a) 
Polypore has heretofore furnished to the Lenders (i) the
consolidated balance sheets and related statements of income, stockholders’
equity and cash flows of Polypore and its consolidated subsidiaries as of and
for the fiscal year ended December 30, 2006, audited by and accompanied by the
unqualified opinion of Ernst & Young LLP, independent public accountants
and (ii) the unaudited consolidated balance sheet and related statements
of income, stockholders’ equity and cash flows of Polypore and its consolidated
subsidiaries as of and for each fiscal quarter subsequent to December 30, 2006
ended 45 days before the Restatement Effective Date.  Such financial statements present fairly, in
all material respects, the financial condition and results of operations and
cash flows of Polypore and its consolidated subsidiaries as of such dates and
for such periods.  Such balance sheets
and the notes thereto disclose all material liabilities, direct or contingent,
of Polypore and its consolidated subsidiaries as of the dates thereof.  Such financial statements were prepared in
accordance with GAAP applied on a consistent basis, except that the unaudited
financial statements are subject to normal year-end adjustments and do not
contain notes thereto.

(b)                                 Polypore
has heretofore delivered to the Lenders the unaudited pro forma consolidated
balance sheet of Polypore and its consolidated subsidiaries at March 31, 2007,
prepared giving effect to the Transactions as if they had occurred on such
date.  Such pro forma financial
statements have been prepared in good faith by Polypore, based on the
assumptions used to prepare the pro forma financial information contained in
the Confidential Information Memorandum (which assumptions are believed by
Polypore on the Restatement Effective Date to be reasonable), are based on the
best information available to Polypore as of the date of delivery thereof,
accurately reflect, in all material respects, all adjustments required to be
made to give effect to the Transactions and present fairly, in all material
respects, on a pro forma basis the estimated consolidated financial position of
Polypore and its consolidated subsidiaries as of such date and for such
periods, assuming that the Transactions had actually occurred at such date or
at the beginning of such period, as the case may be.

SECTION 3.6.  No Material Adverse Change.  No event, change or condition has occurred
that has had, or could reasonably be expected to have, a material adverse
effect on the business, operations, assets, liabilities,

 55
 

financial condition or results of operations of the
Group Members, taken as a whole, since December 30, 2006.

SECTION
3.7.  Title to Properties;
Possession Under Leases. 
(a)  Each Group Member has good
and marketable title to, or valid leasehold interests in, all its material
properties and material assets, except for
minor defects in title that do not materially interfere with its ability to
conduct its business or to utilize such assets for their intended purposes and
Liens permitted by Section 6.2 and except where the failure to have such title
could not reasonably be expected to have, individually or in the aggregate, a Material
Adverse Effect.  All such material
properties and assets are free and clear of Liens, other than Liens expressly
permitted by Section 6.2.

(b)                                 Each
Group Member has complied with all material obligations due and payable or
required to be performed under all material leases to which it is a party and
all such material leases are in full force and effect.  Each Group Member enjoys peaceful and
undisturbed possession under all such leases, except where the failure to so
enjoy could not reasonably be expected to have a Material Adverse Effect.

SECTION
3.8.  Subsidiaries.  Schedule 3.8 sets forth as of the
Restatement Effective Date a list of all Subsidiaries and the percentage
ownership interest of Holdings or Polypore therein.  The shares of Capital Stock so indicated on
Schedule 3.8 are owned by Holdings or Polypore, directly or indirectly, free
and clear of all Liens (other than Liens created under the Security Documents).

SECTION
3.9.  Litigation; Compliance
with Laws.  (a)  There are not any actions, suits or
proceedings at law or in equity or by or before any Governmental Authority now
pending or, to the knowledge of Holdings or Polypore, threatened against or
affecting any Group Member or any business, property or rights of any such
Person (i) that involve any Loan Document or the Transactions or
(ii) as to which there is a reasonable possibility of an adverse
determination and that, if adversely determined, could reasonably be expected,
individually or in the aggregate, to result in a Material Adverse Effect.

(b)                                 No
Group Member nor any of their respective material properties or material assets
is in violation of, nor will the continued operation of their material
properties and material assets as currently conducted violate, any law, rule or
regulation (including any zoning, building, Environmental Law, ordinance, code
or approval or any building permits), or is in default with respect to any
judgment, writ, injunction, decree or order of any Governmental Authority,
where such violation or default could reasonably be expected to result in a
Material Adverse Effect.

SECTION
3.10.  Agreements.  (a)  No
Group Member is a party to any agreement or instrument or subject to any
corporate restriction that has resulted or could reasonably be expected to result
in a Material Adverse Effect.

(b)                                 No
Group Member is in default in any manner under any provision of any indenture
or other agreement or instrument evidencing Indebtedness, or any other
agreement or instrument to which it is a party or by which it or any of its
properties or assets are or may be bound, where such default could reasonably
be expected to result in a Material Adverse Effect.

SECTION
3.11.  Federal Reserve
Regulations.  (a)  No Group Member is engaged principally, or as
one of its important activities, in the business of extending credit for the
purpose of buying or carrying Margin Stock.

(b)                                 No
part of the proceeds of any Loan or any Letter of Credit will be used, whether
directly or indirectly, and whether immediately, incidentally or
ultimately, for any purpose that entails a violation

 56
 

of, or that is
inconsistent with, the provisions of the Regulations of the Board, including
Regulation T, U or X.

SECTION
3.12.  Investment Company Act.  No Group Member is an “investment company” as
defined in, or subject to regulation under, the Investment Company Act of 1940.

SECTION
3.13.  Use of Proceeds.  The Borrower will use the proceeds of the
Loans (other than any Incremental Term Loans) and will request the issuance of
Letters of Credit only for the purposes specified in Section 5.8.  The Borrower will use the proceeds of any
Incremental Term Loans solely as set forth in the applicable Incremental Term
Loan Assumption Agreement.

SECTION
3.14.  Tax Returns.  Each Group Member has filed or caused to be
filed all Federal and all material state, local and foreign tax returns or
materials required to have been filed by it and has paid or caused to be paid
all material taxes due and payable by it and all assessments received by it,
except taxes that are being contested in good faith by appropriate proceedings
and for which the relevant Group Member shall have set aside on its books
adequate reserves and except for taxes the nonpayment of which could not
reasonably be expected to have a Material Adverse Effect.

SECTION
3.15.  No Material
Misstatements. 
None of (a) the Confidential Information Memorandum or (b) any other
information, report, financial statement, exhibit or schedule furnished by or
on behalf of Holdings or Polypore to the Administrative Agent or any Lender in
connection with the negotiation of any Loan Document or included therein or
delivered pursuant thereto contained, which, in the case of clauses (a) and
(b), when taken as a whole and together with the representations and warranties
contained in this Agreement, contains or will contain any material misstatement
of fact or omitted, omits or will omit to state any material fact necessary to
make the statements therein, in the light of the circumstances under which they
were, are or will be made, not misleading; provided that to the extent any such
information, report, financial statement, exhibit or schedule was based upon or
constitutes a forecast or projection, each of Holdings and Polypore represents
only that it acted in good faith and utilized reasonable assumptions and due
care in the preparation of such information, report, financial statement,
exhibit or schedule and it is understood that actual results may differ from
forecasts and projections.

SECTION
3.16.  Employee Benefit Plans.  Each of Polypore and each of its ERISA
Affiliates is in compliance in all material respects with the applicable
provisions of ERISA and the Code and the regulations and published
interpretations thereunder.  No ERISA
Event has occurred or is reasonably expected to occur that, when taken together
with all other such ERISA Events, could reasonably be expected to result in a
Material Adverse Effect.  The present
value of all benefit liabilities under any underfunded Plan (based on the
assumptions used to fund such plan and when considered together with all such
underfunded Plans) did not, as of the last annual valuation dates applicable
thereto, exceed the fair market value of the assets of such underfunded Plans
by an amount that could reasonably be expected to result in a Material Adverse
Effect.

SECTION
3.17.  Environmental Matters.  (a) 
Except as set forth in Schedule 3.17 and except with respect to any
other matters that, individually or in the aggregate, could not reasonably be
expected to result in a Material Adverse Effect, no Group Member (i) has
failed to comply with any Environmental Law or to obtain, maintain or comply
with any permit, license or other approval required under any Environmental
Law, (ii) has become subject to any Environmental Liability,
(iii) has received notice of any claim with respect to any Environmental
Liability or (iv) knows of any basis for any Environmental Liability.

(b)                                 Since
the Restatement Effective Date, there has been no change in the status of the
matters disclosed on Schedule 3.17 that, individually or in the aggregate,
has resulted in, or could reasonably be expected to result in, a Material
Adverse Effect.

 57
 

SECTION
3.18.  Insurance.  Schedule 3.18 sets forth a true,
complete and correct description of all insurance maintained by Polypore or by
Polypore for its Subsidiaries as of the Restatement Effective Date.  As of each such date, such insurance is in
full force and effect and all premiums have been duly paid if due.  Polypore and its Subsidiaries have insurance
in such amounts and covering such risks and liabilities as are, when considered
in its entirety, in the good faith judgment of Polypore prudent in the ordinary
course of business of Polypore and its Subsidiaries.

SECTION
3.19.  Security Documents.  (a) 
The Guarantee and Collateral Agreement is effective to create in favor
of the Administrative Agent, for the ratable benefit of the Secured Parties, a
legal, valid and enforceable security interest in the Collateral (as defined in
the Guarantee and Collateral Agreement) and the proceeds thereof and
(i) if the Pledged Collateral (as defined in the Guarantee and Collateral
Agreement) has been delivered to the Administrative Agent, the Guarantee and
Collateral Agreement shall constitute a fully perfected first priority Lien on,
and security interest in, all right, title and interest of the Loan Parties in
such Pledged Collateral, in each case prior and superior in right to any other
Person, and (ii) if financing statements in appropriate form have been filed in
the offices specified on Schedule 3.19(a), the Lien created under the Guarantee
and Collateral Agreement will constitute a fully perfected Lien on, and
security interest in, all right, title and interest of the Loan Parties in all
such Collateral as to which a security interest may be perfected by such a
filing (other than Intellectual Property, as defined in the Guarantee and
Collateral Agreement), in each case prior and superior in right to any other
Person, other than with respect to Liens expressly permitted by Section 6.2.

(b)                                 If
the Guarantee and Collateral Agreement has been recorded with the United States
Patent and Trademark Office and the United States Copyright Office, and
financing statements in appropriate form have been filed in the offices
specified on Schedule 3.19(a), the Guarantee and Collateral Agreement shall
constitute a fully perfected Lien on, and security interest in, all right,
title and interest of the Loan Parties in the Intellectual Property (as defined
in the Guarantee and Collateral Agreement) in which a security interest may be
perfected by filing in the United States and its territories and possessions,
in each case prior and superior in right to any other Person (it being
understood that subsequent recordings in the United States Patent and Trademark
Office and the United States Copyright Office may be necessary to perfect a
Lien on registered trademarks, trademark applications and copyrights acquired
by the Loan Parties after the Restatement Effective Date).

(c)                                  The
Mortgages are effective to create in favor of the Administrative Agent, for the
ratable benefit of the Secured Parties, a legal, valid and enforceable Lien on
all of the Loan Parties’ right, title and interest in and to the Mortgaged
Property thereunder and the proceeds thereof, and if the Mortgages have been
filed in the offices specified on Schedule 3.19(d), the Mortgages shall
constitute a fully perfected Lien on, and security interest in, all right,
title and interest of the Loan Parties in such Mortgaged Property and the
proceeds thereof, in each case prior and superior in right to any other Person,
other than with respect to the rights of Persons pursuant to Liens expressly
permitted by Section 6.2.

SECTION
3.20.  Location of Real
Property and Leased Premises.  Schedule 3.20(a) lists completely and
correctly as of the Restatement Effective Date all domestic real property owned
by Polypore and the Subsidiaries and the addresses thereof.  Polypore and the Subsidiaries, as the case
may be, as of the Restatement Effective Date, own in fee all the real property
set forth on Schedule 3.20(a). 
Schedule 3.20(b) lists completely and correctly as of the Restatement
Effective Date all material domestic real property leased by Polypore and the
Subsidiaries and the addresses thereof. 
Polypore and the Subsidiaries, as the case may be, as of the Restatement
Effective Date, have valid leasehold interests in all the real property set
forth on Schedule 3.20(b).

SECTION 3.21.  Labor Matters.  As of the Restatement Effective Date, there
are no strikes, lockouts or slowdowns against any Group Member pending or, to
the knowledge of Holdings or Polypore, threatened.  The

 58
 

consummation of the Transactions will not give rise to
any right of termination or right of renegotiation on the part of any union
under any collective bargaining agreement to which any Group Member is
bound.  Except to the extent any of the
following, individually or in the aggregate, could not reasonably be expected
to have a Material Adverse Effect, (a) the hours worked by and payments made to
employees of each Group Member have not been in violation in any material
respect of the Fair Labor Standards Act or any other applicable Federal, state,
local or foreign law dealing with such matters and (b) all payments due from
any Group Member, or for which any claim may be made against any Group Member,
on account of wages and employee health and welfare insurance and other
benefits, have been paid or accrued as a liability on the books of such Group
Member.

SECTION
3.22.  Solvency.  Immediately after the consummation of the
Transactions to occur on the Restatement Effective Date and immediately
following the making of each Loan and after giving effect to the application of
the proceeds of each Loan, (a) the fair value of the assets of the Loan Parties
taken as a whole, at a fair valuation, will exceed their debts and liabilities,
subordinated, contingent or otherwise; (b) the present fair saleable value of
the property of the Loan Parties taken as a whole will be greater than the
amount that will be required to pay the probable liability of their debts and
other liabilities, subordinated, contingent or otherwise, as such debts and
other liabilities become absolute and matured; (c) the Loan Parties taken as a
whole will be able to pay their debts and liabilities, subordinated, contingent
or otherwise, as such debts and liabilities become absolute and matured; and
(d) the Loan Parties taken as a whole will not have unreasonably small capital
with which to conduct the business in which they are engaged as such business
is now conducted and is proposed to be conducted following the Restatement
Effective Date.

SECTION
3.23.  Senior Indebtedness.  The Obligations constitute “Senior
Indebtedness” under and as defined in the Senior Subordinated Note Indenture.

SECTION
3.24.  Certain Treasury
Regulation Matters. 
The Borrower does not intend to treat the Loans and related transactions
as being a “reportable” transaction (within the meaning of Treasury Regulation
1.6011-4).  The Borrower acknowledges
that the Administrative Agent and one or more of the Lenders may treat its
Loans as part of a transaction that is subject to Treasury Regulation Section
301.6112-1 to the extent that the Borrower’s application of the proceeds of the
Loans requires the same and the Administrative Agent and such Lender or
Lenders, as applicable, may, in connection therewith, maintain such lists and
other records as they may determine is required by such Treasury Regulation.

SECTION
3.25.  Foreign Assets Control
Regulations, Etc. 
None of the requesting or borrowing of the Loans, the requesting or
issuance, extension or renewal of any Letters of Credit or the use of the
proceeds of any thereof will violate the Trading With the Enemy Act (50 U.S.C.
§ 1 et seq., as amended) (the “Trading With the Enemy Act”) or any of
the foreign assets control regulations of the United States Treasury Department
(31 CFR, Subtitle B, Chapter V, as amended) (the “Foreign Assets Control
Regulations”) or any enabling legislation or executive order relating
thereto (which for the avoidance of doubt shall include, but shall not be
limited to (a) Executive Order 13224 of September 21, 2001 Blocking Property
and Prohibiting Transactions With Persons Who Commit, Threaten to Commit, or
Support Terrorism (66 Fed. Reg. 49079 (2001)) (the “Executive Order”)
and (b) the Patriot Act).  To the
knowledge of Polypore, neither Polypore nor any of its Subsidiaries (a) is a “blocked person” as described in the Executive
Order, the Trading With the Enemy Act or the Foreign Assets Control Regulations
or (b) engages transactions with any such “blocked person” blocked by such
order, law or regulation.

located is designated (i) a “flood hazard area” in any Flood Insurance Rate Map
published by the Federal Emergency Management Agency (or any successor agency),
obtain flood insurance in such total amount as the Administrative Agent or the

respect to any such tax, assessment, charge or levy so long as (a) the validity
or amount thereof shall be contested in good faith by appropriate proceedings
and Polypore shall have set aside on its books adequate reserves with respect
thereto in accordance with GAAP and such contest operates to suspend collection
of the contested obligation, tax, assessment or charge and enforcement of a
Lien and, in the case of a Mortgaged Property, there is no risk of forfeiture
of such property or (b) the nonpayment thereof could not reasonably be expected
to result in a Material Adverse Effect.

SECTION
5.4.  Financial Statements,
Reports, etc.  In
the case of Polypore, furnish to the Administrative Agent (either physically or

(d)                                 any

written notice of any change in (i) any Loan Party’s legal name, (ii) the
jurisdiction of organization or formation of any Loan Party, (iii) any Loan

Agent to continue at all times following such change to have a valid, legal and
perfected security interest in all the Collateral.  Holdings and Polypore also agree promptly to
notify the Administrative Agent if any material portion of the Collateral is
damaged or destroyed.

(b)                                 In

SECTION
5.7.  Maintaining Records;
Access to Properties and Inspections.  Keep proper books of record and account in
which full, true and correct entries in conformity with GAAP and all requirements
of law are made of all dealings and transactions in relation to its business
and activities.  Each Loan Party will,
and will cause each of its subsidiaries to, permit any representatives
designated by the Administrative Agent or any Lender to visit and inspect the
financial records and the properties of Holdings, Polypore or any Material
Subsidiary at reasonable times and as often as reasonably requested (but not,
except during the continuance of an Event of Default, more than two times per
fiscal year) and to make extracts from and copies of such financial records,
and permit any representatives designated by the Administrative Agent or any
Lender to discuss the affairs, finances and condition of Holdings, Polypore or
any Material Subsidiary with the officers thereof and independent accountants

entitled to have a representative present at all such discussions and to obtain

by the Administrative Agent or any Lender to any third party.

SECTION

financing statements, agreements and instruments, and take all further action
(including (i) filing Uniform Commercial Code and other financing statements,
mortgages and deeds of trust and (ii) delivering duly executed deposit account
control agreements as contemplated by, and within the time period referred to
in, the Guarantee and

 66
 

Collateral Agreement) that may be required under
applicable law, or that the Required Lenders or the Administrative Agent may
reasonably request, in order to effectuate the transactions contemplated by the
Loan Documents and in order to grant, preserve, protect and perfect the
validity and first priority of the security interests created or intended to be
created by the Security Documents. 
Polypore will cause any subsequently acquired or organized Domestic Subsidiary
(other than any Inactive Subsidiary) or any Domestic Subsidiary that ceases to
be an Inactive Subsidiary to become a Loan Party by executing the Guarantee and
Collateral Agreement and each other applicable Security Document in favor of
the Administrative Agent.   In addition,
subject to the last sentence of this Section 5.9, from time to time, Polypore
will, at its cost and expense, promptly secure the Obligations by pledging or
creating, or causing to be pledged or created, perfected security interests
with respect to such of its assets and properties as the Administrative Agent
or the Required Lenders shall designate (it being understood that it is the
intent of the parties that the Obligations shall be secured by substantially
all the assets of Polypore and its Subsidiaries (including real and other
properties acquired subsequent to the Restatement Effective Date, but excluding
real property with a value of less than $5,000,000, leasehold real property,
other immaterial leasehold property, and other Excluded Property (as defined in
the Guarantee and Collateral Agreement). 
Such security interests and Liens will be created under the Security
Documents and other security agreements, mortgages, deeds of trust and other
instruments and documents in form and substance satisfactory to the Administrative
Agent, and Polypore shall deliver or cause to be delivered to the Lenders all
such instruments and documents (including legal opinions, title insurance
policies and lien searches) as the Administrative Agent shall reasonably
request to evidence compliance with this Section 5.9.  Polypore agrees to provide such evidence as
the Administrative Agent shall reasonably request as to the perfection and
priority status of each such security interest and Lien.  In furtherance of the foregoing, Polypore will
give prompt notice to the Administrative Agent of the acquisition by it or any
of the Domestic Subsidiaries of any real property (or any interest in real
property) having a value in excess of $5,000,000.  The actions required under this Section 5.9
shall be taken with 30 days (or such later time as may be acceptable to the
Administrative Agent) after the event giving rise to the requirement to take
such action.  Notwithstanding the
foregoing, (x) the Administrative Agent shall not take a security interest in
those assets as to which the Administrative Agent shall determine, in its
reasonable discretion, that the cost of obtaining such Lien (including any
mortgage, stamp, intangibles or other tax) are excessive in relation to the
benefit to the Lenders of the security afforded thereby and (y) Liens required
to be granted pursuant to this Section 5.9 shall be subject to exceptions and
limitations consistent with those set forth in the Collateral Documents as in
effect on the Restatement Effective Date (to the extent appropriate in the
applicable jurisdiction).

SECTION
5.10.  Certain Treasury
Regulation Matters. 
In the event the Borrower determines to take any action inconsistent
with its intention as set forth in the first sentence of Section 3.24, it will
promptly notify the Administrative Agent thereof.

SECTION
5.11.  Hedging Agreements.  In the case of Polypore, maintain Hedging
Agreements with one or more Lenders (or Affiliates thereof) to the extent
necessary to provide that at least 50% of the aggregate principal amount of
Funded Debt of Polypore outstanding on the Restatement Effective Date is
subject to either a fixed interest rate or interest rate protection for a
period of not less than two years from the Restatement Effective Date, which
Hedging Agreements shall have terms and conditions reasonably satisfactory to
the Administrative Agent.

SECTION
5.12.  Environmental Laws.  Except, in each case, as would not,
individually or in the aggregate, have a Material Adverse Effect:

(a)  Comply in
all material respects with, and use reasonable efforts to ensure compliance in
all material respects by all tenants and subtenants, if any, with, all
applicable Environmental Laws, and obtain and comply in all material respects
with and maintain, and use reasonable efforts to ensure that all

 67
 

tenants and subtenants
obtain and comply in all material respects with and maintain, any and all
Environmental Permits required of them by any applicable Environmental
Laws.  For purposes of this Section
5.12(a), noncompliance with the foregoing shall be deemed not to constitute a
breach of this covenant, provided, that upon learning of any actual or
suspected noncompliance, Polypore shall promptly undertake reasonable efforts
to achieve compliance.

(b)                               Conduct
and complete in all material respects all investigations, studies, sampling and
testing, and all remedial, removal and other actions required to be undertaken
by any Group Member under Environmental Laws and promptly comply with all
orders and directives applicable to any Group Member of all Governmental
Authorities regarding Environmental Laws; provided, however, that
this covenant shall be deemed not violated if the relevant Group Member
promptly challenges in good faith any such order or directive in a manner
consistent with all applicable Environmental Laws and other Requirements of Law
and pursues such challenge or challenges diligently.

(c)                                Generate,
use, treat, store, release, dispose of, and otherwise manage Materials of
Environmental Concern in a manner that would not reasonably be expected to
result in a material liability to any Group Member or to materially affect any
real property owned or leased by any of them; and take reasonable efforts to
prevent any other Person from generating, using, treating, storing, releasing,
disposing of, or otherwise managing Materials of Environmental Concern in a
manner that could reasonably be expected to result in a material liability to,
or materially affect any real property owned or operated by, any Group Member.  For purposes of this Section 5.12(c),
noncompliance with the foregoing shall be deemed not to constitute a breach of
this covenant, provided, that, upon learning of any actual or suspected
noncompliance, Polypore shall promptly undertake reasonable efforts to remove
such Materials of Environmental Concern or otherwise remediate them in a manner
consistent with applicable Environmental Law.

(d)                               Maintain,
update as appropriate, and implement in all material respects an ongoing
program reasonably designed to ensure that all the properties and operations of
the Group Members are regularly and reasonably reviewed by competent
professionals to identify and promote compliance with and to reasonably and
prudently manage any liabilities or potential liabilities under any Environmental
Law that may affect any Group Member, including, without limitation, compliance
and liabilities relating to:  discharges
to air and water; acquisition, transportation, storage and use of hazardous
materials; waste disposal; repair, maintenance and improvement of properties;
employee health and safety; species protection; and recordkeeping.

ARTICLE
VI

Negative Covenants

Each of Holdings
and Polypore covenants and agrees with each Lender that, so long as this
Agreement shall remain in effect and until the Commitments have been terminated
and the principal of and interest on each Loan, all Fees and all other expenses
or amounts payable under any Loan Document have been paid in full and all
Letters of Credit have been cancelled or have expired and all amounts drawn
thereunder have been reimbursed in full, unless the Required Lenders (or, in
the case of Sections 6.10 and 6.11, the Required Revolving Lenders) shall
otherwise consent in writing, neither Holdings nor Polypore will, nor will they
cause or permit any of the Material Subsidiaries (or, in the case of Section
6.1, any of the Subsidiaries) to:

SECTION 6.1.  Indebtedness.  Directly
or indirectly, create, incur, issue, assume, guarantee, acquire, become liable,
contingently or otherwise, with respect to, or otherwise become responsible for
payment of (collectively, “incur”) any Indebtedness (other than Permitted
Indebtedness); provided,

 68
 

however, that if no Default or Event of Default shall
have occurred and be continuing at the time of or as a consequence of the
incurrence of any such Indebtedness, Polypore and the Guarantors may incur
Indebtedness (including Acquired Indebtedness), and Subsidiaries of Polypore
that are not Guarantors may incur Acquired Indebtedness in an aggregate amount
not to exceed $20,000,000 at any time outstanding, in each case if on the date
of the incurrence of such Indebtedness, after giving effect to the incurrence
thereof, the Consolidated Fixed Charge Coverage Ratio would have been greater
than 2.0 to 1.0.  The maximum amount of
Indebtedness that Polypore and its Subsidiaries may incur pursuant to this
covenant shall not be deemed to be exceeded, with respect to any outstanding
Indebtedness, solely as a result of fluctuations in the exchange rate of
currencies.  When calculating capacity
for the incurrence of additional Indebtedness by Polypore and its Subsidiaries
pursuant to this covenant the exchange rate of currencies shall be measured as
of the date of such calculation.

SECTION
6.2.  Liens.  Create, incur, assume or suffer to exist any
Lien on any property or assets (including Capital Stock or other securities of
any Person, including any Subsidiary) now owned or hereafter acquired by it or
on any income or revenues or rights in respect of any thereof, except:

not apply to any other property or assets of Polypore or any Subsidiary, (iii)

restrictions, easements, rights-of-way, restrictions on use of real property

property subject thereto or interfere with the ordinary conduct of the business
of Polypore or any of its Subsidiaries as currently operated;

SECTION
6.5.  Mergers, Consolidations
and Sales of Assets. 
(a)  In the case of Polypore, in a single
transaction or series of related transactions, consolidate or merge with or
into any Person, or sell, assign, transfer, lease, convey or otherwise dispose
of (or cause or permit any Subsidiary to sell, assign, transfer, lease, convey
or otherwise dispose of) all or substantially all of Polypore’s assets
(determined on a consolidated basis for Polypore and the Subsidiaries) to any
Person unless:

(i)  
either: (A) Polypore shall be the surviving or continuing corporation; or (B)
the Person (if other than Polypore) formed by such consolidation or into which
Polypore is merged or the Person which acquires by sale, assignment, transfer,
lease, conveyance or other disposition the properties and assets of Polypore
and of the Subsidiaries substantially as an entirety (the “Surviving Entity”):
(x) shall be a corporation organized and validly existing under the laws of the
United States of America or any State thereof or the District of Columbia; and
(y) shall expressly assume pursuant to supplements to the Loan Documents or
other documents or instruments in form reasonably satisfactory to the
Administrative Agent, executed and delivered to the Administrative Agent, the
Obligations;

(ii)  
except in the case of a merger of Polypore with or into a Wholly Owned
Subsidiary that is not a Securitization Entity or Unrestricted Subsidiary of
Polypore and except in the case of a merger entered into solely for the purpose
of reincorporating Polypore in another jurisdiction, immediately after giving
effect to such transaction and the assumption contemplated by clause (i)(B)(y)
above (including giving effect to any Indebtedness and Acquired Indebtedness
incurred in connection with or in respect of such transaction), Polypore or
such Surviving Entity, as the case may be, shall be able to incur at least
$1.00 of additional
Indebtedness (other than Permitted Indebtedness) pursuant to Section 6.1
hereof,

(iii)  
except in the case
of a merger of Polypore with or into a Wholly Owned Subsidiary that is
not a Securitization Entity or Unrestricted Subsidiary and except in the case of a merger entered into solely for the purpose
of reincorporating Polypore in another jurisdiction, immediately after giving
effect to such transaction and the assumption contemplated by clause (i)(B)(y)
above (including, without limitation, giving effect to any Indebtedness and
Acquired Indebtedness incurred and any Lien granted in connection with or in
respect of the transaction), no Default or Event of Default shall have occurred
or be continuing;

 73
 

(iv)  
Polypore or the Surviving Entity shall have delivered to the Administrative
Agent an Officers’ Certificate and an opinion of counsel, each stating that
such consolidation, merger, sale, assignment, transfer, lease, conveyance or
other disposition and, if supplements to the Loan Documents are required in
connection with such transaction, such supplements comply with the applicable
provisions of the Loan Documents and that all conditions precedent in this
Agreement relating to such transaction have been satisfied.

For purposes
of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a
single transaction or series of transactions) of all or substantially all of
the properties or assets of one or more Subsidiaries the Capital Stock of which
constitutes all or substantially all of the properties and assets of Polypore,
shall be deemed to be the transfer of all or substantially all of the
properties and assets of Polypore. However, transfer of assets (i) between or
among Polypore and the Subsidiaries, (ii) between and among Foreign
Subsidiaries or (iii) from Foreign Subsidiaries to Polypore or a Loan Party
will not be subject to this Section 6.5(a).

Notwithstanding
anything in this Section 6.5 to the contrary, the Merger may be consummated if,
and only if, (i) the Parent Notes shall have been paid in full, (ii) the
representations and warranties set forth in Article III hereof and in each
other Loan Document shall be true and correct in all material respects on and
as of the date of the Merger with the same effect as though made on and as of
such date, except to the extent such representations and warranties expressly
relate to an earlier date, in which case they shall be true and correct in all
material respects on and as of such earlier date and (iii) the other conditions
set forth in Section 6.5(a) have been satisfied.  For the purposes of this paragraph, in
determining whether a Default or Event of Default shall have occurred and be
continuing and whether the representations and warranties described in this
paragraph can be made, each transaction, circumstance or event relating to the
Parent or Holdings that is in existence at the time of the Merger shall be
deemed to be in existence with respect to Polypore.

Upon any
consolidation, combination or merger, or any transfer of all or substantially
all of the assets of Polypore in accordance with Section 6.5 hereof, in which
Polypore is not the continuing corporation, the successor Person formed by such
consolidation or into which Polypore is merged or to which such conveyance,
lease or transfer is made shall succeed to, and be substituted for, and may
exercise every right and power of Polypore under this Agreement and the other
Loan Documents with the same effect as if such surviving entity had been named
as such and that, in the event of a conveyance or transfer (but not a lease),
the conveyor or transferor (but not a lessor) shall be released from the
provisions of this Agreement and the other Loan Documents.

(b)                                 In
the case of any Guarantor, consolidate or merge with or into, or sell, assign,
transfer, lease, convey or otherwise dispose of, in a single transaction or
series of related transactions, all or substantially all of its assets to any
Person unless:

(i)  
(except in the case of such Guarantor that has been disposed of in its entirety
to another Person (other than to Polypore or an Affiliate of Polypore), whether
through a merger, consolidation or sale of Capital Stock or through the sale of
all or substantially all of its assets (such sale constituting the disposition
of such Guarantor in its entirety), if in connection therewith Polypore
provides an Officers’ Certificate to the Administrative Agent to the effect
that Polypore will comply with its obligations under Section 2.13 hereof in
respect of such disposition) the resulting, surviving or transferee Person (if
not such Guarantor) shall be a Person organized and validly existing under the
laws of the jurisdiction under which such Guarantor was organized or under the
laws of the United States of America, any State thereof or the District of
Columbia, and such Person shall expressly assume, pursuant to supplements to
the Loan Documents or other

 74
 

documents or instruments in form reasonably
satisfactory to the Administrative Agent, executed and delivered to the
Administrative Agent, the Guarantee of such Guarantor;

(ii)  
except in the case of a merger of such Guarantor with or into Polypore or
another Guarantor and except in the case of a merger entered into solely for
the purpose of reincorporating such Guarantor in another jurisdiction,
immediately after giving effect to such transaction and the assumption
contemplated by the immediately preceding clause (b)(i) (including, without
limitation, giving effect to any Indebtedness and Acquired Indebtedness
incurred and any Lien granted in connection with or in respect of the
transaction), no Default or Event of Default shall have occurred and be
continuing; and

(iii)  
Polypore shall have delivered to the Administrative Agent an Officers’
Certificate and an opinion of counsel, each stating that such consolidation,
merger, sale, assignment, transfer, lease, conveyance or other disposition and,
if supplements to the Loan Documents are required in connection with such
transaction, such supplements comply with the applicable provisions of the Loan
Documents and that all conditions precedent in this Agreement relating to such
transaction have been satisfied

In case of any
such consolidation, merger, sale or conveyance and upon the assumption by the
successor Person, by supplements to the Loan Documents, executed and delivered
to the Administrative Agent and reasonably satisfactory in form to the
Administrative Agent, of the Guarantee of the relevant Guarantor, such
successor Person shall succeed to and be substituted for the Guarantor with the
same effect as if it had been named herein as a Guarantor.

(c)                                  Consummate any Asset Sale unless
(i) such Asset Sale is for consideration at least 75% of which is cash or
Permitted Investments (other than in the case of a like-kind exchange or
trade-in of one asset for another asset used or useful in the business of
Polypore and its Subsidiaries) and (ii) such consideration is at least equal to
the fair market value of the assets being sold, transferred, leased or disposed
of.

SECTION
6.6.  Restricted Payments.  Declare
or make, or agree to declare or make, directly or indirectly, any Restricted
Payment (including pursuant to any Synthetic Purchase Agreement), or incur any

(b)                                 so
long as no Event of Default or Default shall have occurred and be continuing or

Holdings to enable Holdings to repurchase or make distributions to Parent to
enable it to) repurchase Capital Stock of Holdings or Parent owned by employees
of Holdings or Parent, Polypore or the Subsidiaries or make payments to
employees of Holdings or Parent, Polypore or the Subsidiaries upon termination
of employment of such employees (including as a result of retirement or
severance) in connection with the exercise of stock options, stock appreciation
rights or similar equity incentives or equity based incentives pursuant to
management incentive plans or in connection with the death or disability of
such employees in an aggregate amount not to exceed $5,000,000 in any fiscal
year (it being agreed that (i) any amount not utilized in any fiscal year may
be carried forward and utilized in any subsequent fiscal year, (ii) such amount
shall be increased by the amount of cash proceeds received by Holdings from the
sale of Capital Stock of Holdings or Parent to such employees after the
Restatement Effective Date to the extent such proceeds are contributed

 75
 

directly or
indirectly to Polypore as common equity and (iii) any proceeds of key man life
insurance actually received by Polypore or Holdings may be used or distributed
by Polypore or Holdings for purposes of such repurchases without regard to such
amount); provided, that after consummation of the Merger, all references
in this clause (b) to the Parent or Holdings shall be deemed to be references
to Polypore;

(c)                                  prior
to consummation of the Merger, Polypore and Holdings may make Restricted
Payments to Holdings and/or Parent (x)
the proceeds of which shall be applied by Holdings and/or the Parent (A) to pay its franchise taxes and other fees
required to maintain its corporate existence and (B) to pay out of pocket
general corporate and overhead expenses incurred by Holdings and/or the Parent
not to exceed in the case of this clause (B) (together with the total amount of
Investments made for such purpose under Section 6.4(j)) $5,000,000 during any
fiscal year of Polypore and (y) in the form of Tax Payments, to the
extent directly attributable to (or arising as a result of) the operations of
Polypore and the Subsidiaries; provided, however, that
(A) the amount of such dividends (together
with loans and advances made pursuant to Section 6.4(j) for the purpose of
funding Tax Payments) shall not exceed the amount that Polypore and the
Subsidiaries would be required to pay in respect of Federal, State and local
taxes were Polypore and the Subsidiaries to pay such taxes as stand-alone
taxpayers, (B) all Restricted Payments made to Holdings and/or Parent
pursuant to this clause (c) are used by Holdings and/or Parent for the purposes
specified herein within 20 days of the receipt thereof and (C) in the case of
any Restricted Payment made to Holdings pursuant to this clause (c), Holdings
owns, beneficially and of record, 100% of the issued and outstanding Capital
Stock of Polypore at the time of such Restricted Payment;

(d)                                 the
payment of any dividend or the consummation of any irrevocable redemption
within 60 days after the date of declaration of such dividend or notice of such
redemption if the dividend or payment of the redemption price, as the case may
be, would have been permitted on the date of declaration or notice;

(e)                                  any
Restricted Payment made out of the net cash proceeds of the substantially
concurrent sale of, or made by exchange for, Qualified Capital Stock of
Polypore (other than Capital Stock issued or sold to a Subsidiary of Polypore
or an employee stock ownership plan or to a trust established by Polypore or
any Subsidiary for the benefit of their respective employees) or a
substantially concurrent cash capital contribution received by Polypore from
its shareholders; provided, however, that the net cash proceeds
from such sale or such cash capital contribution (to the extent so used for
such Restricted Payment) shall be excluded from the calculation of the
Available Amount;

(f)                                    if
no Default or Event of Default shall have occurred and be continuing or would
occur as a consequence thereof, the declaration and payment of dividends to
holders of any class or series of Designated Preferred Stock (other than
Disqualified Capital Stock), issued after the Restatement Effective Date; provided
that, at the time of the declaration of such dividend, Polypore, after
giving effect to the payment of such dividend on a pro forma basis, would have
had a Consolidated Fixed Charge Coverage Ratio of at least 2.0 to 1.0;

(g)                                 payments
to Holdings for the purpose of permitting, and in an amount equal to the amount
required to permit, Holdings to redeem or repurchase Holdings’ common equity or
options in respect thereof, in each case in connection with the repurchase
provisions of employee stock option or stock purchase agreements or other agreements
to compensate management employees or upon the death, disability, retirement,
severance or termination of employment of management employees; provided
that all such redemptions or repurchases pursuant to this clause (g) shall not
exceed in any fiscal year the sum of (i) $5,000,000 plus (ii) any
amounts not utilized in any preceding fiscal year following the Restatement
Effective Date that were otherwise available under this clause for such
purchases (which aggregate

 76
 

amount shall
be increased by the amount of any net cash proceeds received from the sale
since the Restatement Effective Date of Capital Stock (other than Disqualified
Capital Stock) to members of Polypore’s management team that have not otherwise
been applied to the payment of Restricted Payments through application of the
Available Amount or clause (e) of this Section 6.6 and by the cash proceeds of
any “key-man” life insurance policies which are used to make such redemptions
or repurchases); provided, further, that the cancellation of Indebtedness
owing to Polypore from members of management of Polypore or any Subsidiary in
connection with any repurchase of Capital Stock of Holdings (or warrants or
options or rights to acquire such Capital Stock) will not be deemed to
constitute a Restricted Payment;

(h)                                 repurchases
of Capital Stock deemed to occur upon the exercise of stock options, warrants
or other convertible securities if such Capital Stock represents a portion of
the exercise price thereof;

(i)                                     payments
of dividends on Disqualified Capital Stock issued in compliance with Section

prior to the Merger, dividends, distributions or advances to Holdings or the
Parent to allow the Parent to pay dividends on its Common Stock), of up to 6%

Offering; and

(k)                                  in

of its Subsidiaries to, directly or indirectly, enter into or permit to occur
any transaction or series of related transactions (including, without
limitation, the purchase, sale, lease or exchange of any property or the
rendering of any service) with, or for the benefit of, any of its Affiliates
involving aggregate consideration in excess of $3,000,000 (an “Affiliate
Transaction”), other than Affiliate Transactions on terms that are not
materially less favorable than those that might reasonably have been obtained
in a comparable transaction at such time on an arm’s-length basis from a Person
that is not an Affiliate of Polypore; provided, however, that for a transaction or series of related
transactions with an aggregate value of $10,000,000 or more, at Polypore’s
option, either: (i) a majority of the disinterested members of the Board of
Directors of Polypore shall determine in good faith that such Affiliate
Transaction is on terms that are not materially less favorable than those that
might reasonably have been obtained in a comparable transaction at such time on
an arm’s-length basis from a Person that is not an Affiliate of Polypore, or
(ii) the Board of Directors of Polypore or any such Subsidiary party to such
Affiliate Transaction shall have received an opinion from a nationally recognized
investment banking, appraisal or accounting firm that such Affiliate
Transaction is either fair, from a financial standpoint, to Polypore and its
Subsidiaries or is on terms not materially less favorable than those that might
reasonably have been obtained in a comparable transaction at such time on an
arm’s-length basis from a Person that is not an Affiliate of Polypore; and provided, further,
that for an Affiliate Transaction with an aggregate value of $20,000,000 or
more the Board of Directors of Polypore or any such Subsidiary party to such
Affiliate Transaction shall have received a written opinion from a nationally
recognized investment banking, appraisal or accounting firm that such Affiliate
Transaction is either fair, from a financial standpoint, to Polypore and its
Subsidiaries or is on terns not materially less favorable than those that might
reasonably have been obtained in a comparable transaction at such time on an
arm’s-length basis from a Person that is not an Affiliate of Polypore.

 77

are not otherwise prohibited by this Agreement; (iii) any agreement as in
effect as of the Restatement Effective Date and described on Schedule 6.7 or
any amendment thereto or any transaction contemplated thereby (including
pursuant to any amendment thereto) or by any replacement agreement thereto so
long as any such amendment or replacement agreement is not more disadvantageous
to the Lenders in any material respect than the original agreement as in effect
on the Restatement Effective Date as determined in good faith by the Board of
Directors of Polypore; (iv) Restricted Payments or Investments (other than
Investments made pursuant to Section 6.4(l)) permitted by this Agreement; (v)
transactions effected as part of a Qualified Securitization Transaction; (vi)

agreements which it may enter into thereafter; provided, however, that the existence of, or the
performance by Polypore or any of its Subsidiaries of obligations under, any future
amendment to any such existing agreement or under any similar agreement entered
into after the Restatement Effective Date shall only be permitted by this
clause (ix) to the extent that the terms of any such amendment or new agreement
are not disadvantageous to the Lenders in any material respect; (x)
transactions permitted by, and complying with, the provisions of Section 6.5;

Polypore and Subsidiaries.  (a) 
With respect to Holdings, engage in any business activities or have any
assets or liabilities other than (i) its ownership of the Capital Stock of

Subordinated Note Indenture; Certain Payments of Subordinated Debt.  (a) 
Permit any supplement, modification or amendment of the Senior
Subordinated Note Indenture if the effect of such supplement, modification or
amendment as a whole would materially increase the obligations (including,

manner that would be, or could reasonably be expected to be, materially
detrimental to Polypore or  materially
adverse to the interests of the Lenders, as determined in good faith by
Polypore.

(b)                                 Make

provisions), in respect of, or pay, or offer or commit to pay, or directly or
indirectly (including pursuant to any Synthetic Purchase Agreement) redeem,
repurchase, retire or otherwise acquire for consideration, or set apart any sum
for the aforesaid purposes, any subordinated Indebtedness (provided, however, that the foregoing shall
not prohibit (i) any Refinancings of Indebtedness in accordance with Section
6.1, (ii) the conversion of any such Indebtedness into equity securities or
(iii) any such transaction funded with the Available Amount).

SECTION
6.10.  Capital Expenditures.  (a) 
Permit the aggregate amount of Capital Expenditures made by Polypore and
the Subsidiaries in any fiscal year of Polypore to exceed the sum of (i)
$60,000,000 and (ii) the Acquired CapEx Amount (the “CapEx Basket”).  For purposes of this Section 6.10, the “Acquired
CapEx Amount”, with respect to any Acquired Entity, shall equal the product
of (x) the aggregate amount of Capital Expenditures made by the Acquired Entity
in the two fiscal years prior to the date of the Permitted Acquisition and (y)
0.50.

(b)                                 The
amount of permitted Capital Expenditures set forth in paragraph (a) above
(as adjusted in accordance with the terms thereof) in respect of any fiscal
year (i) shall be increased (but not decreased) by the amount of unused
permitted Capital Expenditures for the two immediately preceding fiscal years; provided,
that Capital Expenditures made pursuant to this Section during any fiscal year
shall be deemed made, first, in respect of amounts carried over from the
fiscal year two years prior thereto pursuant to the preceding sentence, second,
in respect of amounts carried over from the immediately prior fiscal year
pursuant to the preceding sentence, and, third, in respect of amounts
permitted for such fiscal year as provided above and (ii) may, at the option of
Polypore, be increased by up to 50% of the CapEx Basket then in effect (in
which case there shall be a corresponding reduction in the CapEx Basket for the
next succeeding fiscal year).

(c)                                  In
addition to the foregoing, (i) Polypore and its Subsidiaries may make Capital
Expenditures in an aggregate amount not to exceed $10,000,000 during the term
of this Agreement, (ii) Polypore and its Subsidiaries may make Capital
Expenditures using the Available Amount and
(iii) if no Default or Event of Default shall have occurred and be

made within 365 days after receipt of such proceeds).

(d)                                 This
Section 6.10 shall automatically cease to be effective if the Revolving
Commitments have been terminated and all amounts owing in respect of the
Revolving Facility have been paid in full (or, in the case of Letters of
Credit, cash collateralized at 105% of
the face amount thereof).

SECTION

thereof or by acceleration thereof or otherwise;

(c)                                  default

Article VI; provided that the
failure to comply with the Financial Performance Covenant or the CapEx Covenant

respect of any Material Indebtedness, when and as the same shall become due and
payable, or (ii) any other event or condition occurs that results in any

on its or their behalf to cause any Material Indebtedness to become due, or to
require the prepayment, repurchase, redemption or defeasance thereof, prior to

which the insurer has been notified of such judgment or order and does not deny
coverage and of amounts covered by an indemnity from a Person that, in the
reasonable judgment of the Administrative Agent, is creditworthy) from a
party  shall be rendered against
Holdings, Polypore, any Material Subsidiary or any combination thereof and the
same shall remain undischarged for a period of 30 consecutive days during which
execution shall not be effectively stayed, or any action shall be legally taken
by a judgment creditor to levy upon assets or properties of Holdings, Polypore
or any Material Subsidiary to enforce any such judgment;

(j)                                     an

reasonably be expected to have a Material Adverse Effect;

(k)                                  any
Guarantee under the Guarantee and Collateral Agreement for any reason shall
cease to be in full force and effect (other than in accordance with its terms),
or any Guarantor shall deny in writing that it has any further liability under
the Guarantee and Collateral Agreement (other than as a result of the discharge
of such Guarantor in accordance with the terms of the Loan Documents);

 81
 

(l)                                     any
security interest in any material item of Collateral  purported
to be created by any Security Document shall cease to be, or shall be asserted
by Polypore or any other Loan Party not to be, a valid, perfected, first
priority (except as otherwise expressly provided in this Agreement or such
Security Document) security interest in the securities, assets or properties
covered thereby, except to the extent that any such loss of perfection or
priority results from the failure of the Administrative Agent to maintain
possession of certificates representing securities pledged under the Guarantee
and Collateral Agreement and except to the extent that such loss is covered by
a lender’s title insurance policy and the related insurer shall not have denied
or disclaimed in writing that such loss is covered by such title insurance
policy;

(m)                               the
Indebtedness under the Senior Subordinated Notes or any Guarantees thereof
shall cease, for any reason, to be validly subordinated to the Obligations, as
provided in the Senior Subordinated Note Indenture, or any Loan Party or any
Affiliate of any Loan Party shall so assert; or

(n)                                 there
shall have occurred a Change in Control;

then, and in every such event (other than an event
with respect to Holdings or Polypore described in paragraph (g) or (h) (i) -
(v) above), and at any time thereafter during the continuance of such event,
the Administrative Agent may, and at the request of the Required Lenders shall,
by notice to Polypore, take either or both of the following actions, at the
same or different times:  (i) terminate
forthwith the Commitments and (ii) declare the Loans then outstanding to be
forthwith due and payable in whole or in part, whereupon the principal of the
Loans so declared to be due and payable, together with accrued interest thereon
and any unpaid accrued Fees and all other liabilities of Polypore accrued
hereunder and under any other Loan Document, shall become forthwith due and
payable, without presentment, demand, protest or any other notice of any kind,
all of which are hereby expressly waived by Polypore, anything contained herein
or in any other Loan Document to the contrary notwithstanding; and in any event
with respect to Holdings, Polypore or Daramic Holding described in paragraph
(g) or (h) (i) - (v) above, the Commitments shall automatically terminate and
the principal of the Loans (or, in the case of any such event relating solely
to Daramic Holding, the Euro Term Loans) then outstanding, together with
accrued interest thereon and any unpaid accrued Fees and all other liabilities
of Polypore or Daramic Holding, as applicable, accrued hereunder and under any
other Loan Document, shall automatically become due and payable, without
presentment, demand, protest or any other notice of any kind, all of which are
hereby expressly waived by Polypore and Daramic Holding, anything contained
herein or in any other Loan Document to the contrary notwithstanding.

Notwithstanding anything to the contrary contained in
this Article VII, in the event that Polypore would otherwise fail to comply
with the requirements of Sections 6.11 (the “Financial Performance Covenant”) at the end of any fiscal
quarter, at any time within ten days after the date on which a compliance
certificate must be delivered for the end of such fiscal quarter, Polypore
shall have the right (the “Cure
Right”) to include the net cash proceeds of Permitted Cure
Securities (as defined below) received by Polypore during such period in the
calculation of Consolidated EBITDA to the extent provided below (provided
that (a) in each four
fiscal quarter period there shall be a period of at least one fiscal quarter
during which no Cure Right is exercised and (b) in each eight fiscal quarter
period there shall be a period of at least four fiscal quarters during which no
Cure Right is exercised), and upon the receipt by Polypore of such net
cash proceeds (which shall be in the form of a common equity contribution from
Holdings if such Permitted Cure Securities are issued by Holdings) (the “Cure Amount”), the Financial
Performance Covenant shall be recalculated giving effect to the following pro
forma adjustments:

(i)                     Consolidated
EBITDA shall be increased solely for the purpose of measuring the Financial
Performance Covenant and not for any other purpose under this Agreement, by an
amount equal to the Cure Amount; and

 82
 

(ii)                  if,
after giving effect to the foregoing recalculations, Polypore shall then be in
compliance with the requirements of all Financial Performance Covenant,
Polypore shall be deemed to have satisfied the requirements of the Financial
Performance Covenant as of the relevant date of determination with the same
effect as though there had been no failure to comply therewith at such date,
and the applicable breach or default of the Financial Performance Covenant that
would have otherwise occurred on such date but for the application of the
foregoing recalculations shall be deemed not to have occurred.

As used in this Article VII, the term “Permitted Cure Securities” shall
mean an equity security (which shall be deemed to include any common equity
contribution) of Holdings (or, after the Merger, Polypore) having no mandatory
redemption, repurchase, repayment or similar requirements prior to the
six-month anniversary of the Term Loan Maturity Date and upon which all
dividends or distributions, at the election of Holdings or Polypore, as
applicable, may be payable in additional shares of such equity security.

The Agents

SECTION
8.1.  Appointment.  Each Lender hereby irrevocably designates and
appoints the Administrative Agent as the agent of such Lender under this
Agreement and the other Loan Documents, and each such Lender irrevocably
authorizes the Administrative Agent, in such capacity, to take such action on
its behalf under the provisions of this Agreement and the other Loan Documents
and to exercise such powers and perform such duties as are expressly delegated
to the Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental
thereto.  Notwithstanding any provision
to the contrary elsewhere in this Agreement, the Administrative Agent shall not
have any duties or responsibilities, except those expressly set forth herein,
or any fiduciary relationship with any Lender, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Administrative Agent.

SECTION
8.2.  Delegation of Duties.  The Administrative Agent may execute any of
its duties under this Agreement and the other Loan Documents by or through
agents or attorneys-in-fact and shall be entitled to advice of
counsel concerning all matters pertaining to such duties.  The Administrative Agent shall not be
responsible for the negligence or misconduct of any agents or attorneys in-fact
selected by it with reasonable care.

SECTION
8.3.  Exculpatory Provisions.  Neither any Agent nor any of their respective
officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be (i) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or any
other Loan Document (except to the extent that any of the foregoing are found
by a final and nonappealable decision of a court of competent jurisdiction to
have resulted from its or such Person’s own gross negligence or willful
misconduct) or (ii) responsible in any manner to any of the Lenders for any
recitals, statements, representations or warranties made by any Loan Party or
any officer thereof contained in this Agreement or any other Loan Document or
in any certificate, report, statement or other document referred to or provided
for in, or received by the Agents under or in connection with, this Agreement
or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or any other Loan
Document or for any failure of any Loan Party a party thereto to perform its
obligations hereunder or thereunder.  The
Agents shall not be under any obligation to any Lender to ascertain or to
inquire as to the observance or performance of any of the agreements contained
in, or

 83
 

conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of any Loan Party.

SECTION
8.4.  Reliance by
Administrative Agent. 
The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any instrument, writing, resolution, notice,
consent, certificate, affidavit, letter, telecopy, telex or teletype message,
statement, order or other document or conversation believed by it to be genuine
and correct and to have been signed, sent or made by the proper Person or Persons
and upon advice and statements of legal counsel (including counsel to Holdings
or Polypore), independent accountants and other experts selected by the
Administrative Agent.  The Administrative
Agent may deem and treat the payee of any Note as the owner thereof for all
purposes unless a written notice of assignment, negotiation or transfer thereof
shall have been filed with the Administrative Agent.  The Administrative Agent shall be fully
justified in failing or refusing to take any action under this Agreement or any
other Loan Document unless it shall first receive such advice or concurrence of
the Required Lenders (or, if so specified by this Agreement, all Lenders) as it
deems appropriate or it shall first be indemnified to its satisfaction by the
Lenders against any and all liability and expense that may be incurred by it by
reason of taking or continuing to take any such action.  The Administrative Agent shall in all cases
be fully protected in acting, or in refraining from acting, under this Agreement
and the other Loan Documents in accordance with a request of the Required
Lenders (or, if so specified by this Agreement, all Lenders), and such request
and any action taken or failure to act pursuant thereto shall be binding upon
all the Lenders and all future holders of the Loans.

SECTION
8.5.  Notice of Default.  The Administrative Agent shall not be deemed
to have knowledge or notice of the occurrence of any Default or Event of
Default unless the Administrative Agent has received notice from a Lender,
Holdings or Polypore referring to this Agreement, describing such Default or
Event of Default and stating that such notice is a “notice of default”.  In the event that the Administrative Agent
receives such a notice, the Administrative Agent shall give notice thereof to
the Lenders.  The Administrative Agent
shall take such action with respect to such Default or Event of Default as
shall be reasonably directed by the Required Lenders (or, if so specified by
this Agreement, all Lenders); provided that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it
shall deem advisable in the best interests of the Lenders.

SECTION
8.6.  Non-Reliance on Agents
and Other Lenders. 
Each Lender expressly acknowledges that neither the Agents nor any of
their respective officers, directors, employees, agents, attorneys-in-fact
or affiliates have made any representations or warranties to it and that no act
by any Agent hereafter taken, including any review of the affairs of a Loan
Party or any affiliate of a Loan Party, shall be deemed to constitute any
representation or warranty by any Agent to any Lender.  Each Lender represents to the Agents that it
has, independently and without reliance upon any Agent or any other Lender, and
based on such documents and information as it has deemed appropriate, made its
own appraisal of and investigation into the business, operations, property,
financial and other condition and creditworthiness of the Loan Parties and
their affiliates and made its own decision to make its Loans hereunder and
enter into this Agreement.  Each Lender
also represents that it will, independently and without reliance upon any Agent
or any other Lender, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
appraisals and decisions in taking or not taking action under this Agreement
and the other Loan Documents, and to make such investigation as it deems
necessary to inform itself as to the business, operations, property, financial
and other condition and creditworthiness of the Loan Parties and their
affiliates.  Except for notices, reports
and other documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any
duty or responsibility to provide any Lender with any credit or other
information concerning the business, operations, property, condition (financial
or otherwise), prospects or creditworthiness of any

 84
 

Loan Party or any affiliate of a Loan Party that may
come into the possession of the Administrative Agent or any of its officers,
directors, employees, agents, attorneys-in-fact or affiliates.

SECTION
8.7.  Indemnification.  The Lenders agree to indemnify each Agent in
its capacity as such (to the extent not reimbursed by Holdings or Polypore and
without limiting the obligation of Holdings or Polypore to do so), ratably
according to their respective Aggregate Exposure Percentages in effect on the
date on which indemnification is sought under this Section (or, if
indemnification is sought after the date upon which the Commitments shall have
terminated and the Loans shall have been paid in full, ratably in accordance
with such Aggregate Exposure Percentages immediately prior to such date), from
and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind
whatsoever that may at any time (whether before or after the payment of the
Loans) be imposed on, incurred by or asserted against such Agent in any way
relating to or arising out of, the Commitments, this Agreement, any of the
other Loan Documents or any documents contemplated by or referred to herein or
therein or the transactions contemplated hereby or thereby or any action taken
or omitted by such Agent under or in connection with any of the foregoing; provided
that no Lender shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements that are found by a final and
nonappealable decision of a court of competent jurisdiction to have resulted
from such Agent’s gross negligence or willful misconduct.  The agreements in this Section shall survive
the payment of the Loans and all other amounts payable hereunder.

SECTION
8.8.  Agent in Its Individual
Capacity.  Each
Agent and its affiliates may make loans to, accept deposits from and generally
engage in any kind of business with any Loan Party as though such Agent were
not an Agent.  With respect to its Loans
made or renewed by it and with respect to any Letter of Credit issued or
participated in by it, each Agent shall have the same rights and powers under
this Agreement and the other Loan Documents as any Lender and may exercise the
same as though it were not an Agent, and the terms “Lender” and “Lenders” shall
include each Agent in its individual capacity.

SECTION
8.9.  Successor Administrative
Agent.  The
Administrative Agent may resign as Administrative Agent upon 10 days’ notice to
the Lenders and Polypore.  If the
Administrative Agent shall resign as Administrative Agent under this Agreement
and the other Loan Documents, then the Required Lenders shall appoint from
among the Lenders a successor agent for the Lenders, which successor agent
shall (unless an Event of Default under Section 7(b), (c), (g) or (h) with
respect to Polypore shall have occurred and be continuing) be subject to
approval by Polypore (which approval shall not be unreasonably withheld or
delayed), whereupon such successor agent shall succeed to the rights, powers
and duties of the Administrative Agent, and the term “Administrative Agent”
shall mean such successor agent effective upon such appointment and approval,
and the former Administrative Agent’s rights, powers and duties as
Administrative Agent shall be terminated, without any other or further act or
deed on the part of such former Administrative Agent or any of the parties to
this Agreement or any holders of the Loans. 
If no successor agent has accepted appointment as Administrative Agent
by the date that is 10 days following a retiring Administrative Agent’s notice
of resignation, the retiring Administrative Agent’s resignation shall
nevertheless thereupon become effective, and the Lenders shall assume and
perform all of the duties of the Administrative Agent hereunder until such
time, if any, as the Required Lenders appoint a successor agent as provided for
above.  After any retiring Administrative
Agent’s resignation as Administrative Agent, the provisions of this Article
VIII shall inure to its benefit as to any actions taken or omitted to be taken
by it while it was Administrative Agent under this Agreement and the other Loan
Documents.

SECTION
8.10.  Co-Documentation Agents
and Syndication Agent. 
Neither the Co-Documentation Agents nor the Syndication Agent shall have
any duties or responsibilities hereunder in its capacity as such.

(A)  Polypore, provided that no consent of
Polypore shall be required for an assignment to a Lender, an affiliate of a
Lender, an Approved Fund (as defined below) or, if an Event of Default has occurred
and is continuing, any other Person;

(B)  the Administrative Agent, provided
that no consent of the Administrative Agent shall be required for an assignment
of all or any portion of a Term Loan to a Lender, an Affiliate of a Lender or
an Approved Fund; and

(C)  the Issuing Bank, provided that no
consent of the Issuing Bank shall be required for an assignment of all or any
portion of a Term Loan.

(ii) 
Assignments shall be subject to the following additional conditions:

(A)  except in the case of an assignment to a
Lender, an affiliate of a Lender or an Approved Fund or an assignment of the
entire remaining amount of the assigning Lender’s Commitments or Loans under
any Facility, the amount of the Commitments or Loans of the assigning Lender
subject to each such assignment (determined as of the date the Assignment and
Assumption with respect to such assignment is delivered to the Administrative
Agent) shall not be less than $5,000,000 (or, in the case of (x) US$ Term Loans
and Incremental Term Loans, $1,000,000 or (y) Euro Term Loans, €1,000,000)
unless each of Polypore and the Administrative Agent otherwise consent, provided
that (1) no such consent of Polypore shall be required if an Event of Default
has occurred and is continuing and (2) such amounts shall be aggregated in
respect of each Lender and its affiliates or Approved Funds, if any;

(B)  the parties to each assignment shall execute
and deliver to the Administrative Agent an Assignment and Assumption, together
with a processing and recordation fee of $3,500; and

 87
 

(C)  the Assignee, if it shall not be a Lender,
shall deliver to the Administrative Agent an administrative questionnaire in which the Assignee designates one or more
credit contacts to whom all syndicate-level information (which may contain
material non-public information about Polypore and its Affiliates and their
related parties or their respective securities) will be made available and who
may receive such information in accordance with the assignee’s compliance
procedures and applicable laws, including Federal and state securities laws.

For the purposes of this Section 9.4, “Approved
Fund” means any Person (other than a natural person) that is engaged in
making, purchasing, holding or investing in bank loans and similar extensions
of credit in the ordinary course of its business and that is administered or
managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an
Affiliate of an entity that administers or manages a Lender.

(iii)  Subject
to acceptance and recording thereof pursuant to paragraph (b)(iv) below,
from and after the effective date specified in each Assignment and Assumption
the Assignee thereunder shall be a party hereto and, to the extent of the
interest assigned by such Assignment and Assumption, have the rights and
obligations of a Lender under this Agreement, and the assigning Lender
thereunder shall, to the extent of the interest assigned by such Assignment and
Assumption, be released from its obliga­tions under this Agreement (and, in the
case of an Assignment and Assumption covering all of the assigning Lender’s
rights and obligations under this Agreement, such Lender shall cease to be a
party hereto but shall continue to be entitled to the benefits of
Sections 2.14, 2.15, 2.19 and 9.5). 
Any assignment or transfer by a Lender of rights or obligations under
this Agreement that does not comply with this Section 9.4 shall be treated for
purposes of this Agreement as a sale by such Lender of a participation in such
rights and obligations in accordance with paragraph (c) of this Section.

(iv)  The
Administrative Agent, acting for this purpose as an agent of the Borrower,
shall maintain at one of its offices a copy of each Assignment and Assumption
delivered to it and a register for the recordation of the names and addresses
of the Lenders, and the Commitments of, and principal amount of the Loans and
L/C Obligations owing to, each Lender pursuant to the terms hereof from time to
time (the “Register”).  The
entries in the Register shall be conclusive, and the Borrower, the
Administrative Agent, the Issuing Bank and the Lenders may treat each Person
whose name is recorded in the Register pursuant to the terms hereof as a Lender
hereunder for all purposes of this Agreement, notwithstanding notice to the
contrary.

(v)  Upon its
receipt of a duly completed Assignment and Assumption executed by an assigning
Lender and an Assignee, the Assignee’s completed administrative questionnaire
(unless the Assignee shall already be a Lender hereunder), the processing and
recordation fee referred to in paragraph (b) of this Section and any
written consent to such assignment required by paragraph (b) of this Section,
the Administrative Agent shall accept such Assignment and Assumption and record
the information contained therein in the Register.  No assignment shall be effective for purposes
of this Agreement unless it has been recorded in the Register as provided in
this paragraph.

(c)          (i) 
Any Lender may, without the consent of Polypore or the Administrative
Agent, sell participations to one or more banks or other entities (a “Participant”)
in all or a portion of such Lender’s rights and obligations under this
Agreement (including all or a portion of its Commitments and the Loans owing to
it); provided that (A) such Lender’s obligations under this
Agreement shall remain unchanged, (B) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (C) the Borrower, the Administrative Agent, the Issuing Bank and the
other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender’s rights and obligations under this Agreement.  Any agreement pursuant to which a Lender
sells such a participation shall provide that such Lender shall retain the sole
right to enforce this Agreement and to approve any

 88
 

amendment, modification or waiver of any provision of this Agreement; provided
that such agreement may provide that such Lender will not, without the consent
of the Participant, agree to any amendment, modification or waiver that (1)
requires the consent of each Lender directly affected thereby pursuant to
Section 9.8(b) and (2) directly affects such Participant.  Subject to paragraph (c)(ii) of this Section,
Polypore agrees that each Participant shall be entitled to the benefits of
Sections 2.14, 2.15 and 2.19 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to paragraph (b) of this
Section.  To the extent permitted by law,
each Participant also shall be entitled to the benefits of Section 2.17 as
though it were a Lender, provided such Participant shall be subject to
Section 9.6 as though it were a Lender.

(ii)  A
Participant shall not be entitled to receive any greater payment under Section
2.14 or 2.19 than the applicable Lender would have been entitled to receive
with respect to the participation sold to such Participant, unless the sale of
the participation to such Participant is made with Polypore’s prior written
consent.  Any Participant that is a
Non-U.S. Lender shall not be entitled to the benefits of Section 2.19
unless such Participant complies with Section 2.19(e).

(d)                                 Any
Lender may at any time pledge or assign a security interest in all or any
portion of its rights under this Agreement to secure obligations of such
Lender, including any pledge or assignment to secure obligations to a Federal
Reserve Bank, and this Section shall not apply to any such pledge or assignment
of a security interest; provided that no such pledge or assignment of a
security interest shall release a Lender from any of its obligations hereunder
or substitute any such pledgee or Assignee for such Lender as a party hereto.

(e)                                  Notwithstanding
the foregoing, any Conduit Lender may assign any or all of the Loans it may
have funded hereunder to its designating Lender without the consent of Polypore
or the Administrative Agent and without regard to the limitations set forth in
Section 9.4(b).  Each of Holdings, the
Borrower, each Lender and the Administrative Agent hereby confirms that it will
not institute against a Conduit Lender or join any other Person in instituting
against a Conduit Lender any bankruptcy, reorganization, arrangement,
insolvency or liquidation proceeding under any state bankruptcy or similar law,
for one year and one day after the payment in full of the latest maturing
commercial paper note issued by such Conduit Lender; provided, however,
that each Lender designating any Conduit Lender hereby agrees to indemnify,
save and hold harmless each other party hereto for any loss, cost, damage or
expense arising out of its inability to institute such a proceeding against
such Conduit Lender during such period of forbearance.

SECTION
9.5.  Expenses; Indemnity.  (a) 
Polypore and Holdings agree, jointly and severally, to pay all
reasonable documented out-of-pocket expenses incurred by the Administrative
Agent, the Issuing Bank and the Swingline Lender in connection with the
syndication of the credit facilities provided for herein and the preparation
and administration of this Agreement and the other Loan Documents or in
connection with any amendments, modifications or waivers of the provisions
hereof or thereof (whether or not the transactions hereby or thereby
contemplated shall be consummated) or incurred by the Administrative Agent or
any Lender in connection with the enforcement or protection of its rights in
connection with this Agreement and the other Loan Documents or in connection
with the Loans made or Letters of Credit issued hereunder, including the
reasonable fees, charges and disbursements of Simpson Thacher & Bartlett
LLP, counsel for the Administrative Agent, and, in connection with any such
enforcement or protection, the fees, charges and disbursements of any other
counsel for the Administrative Agent or any Lender.

(b)                                 Polypore
and Holdings agree, jointly and severally, to indemnify the Administrative
Agent, each Lender, the Issuing Bank and each Related Party of any of the
foregoing Persons (each such Person being called an “Indemnitee”)
against, and to hold each Indemnitee harmless from, any and all

 89
 

losses,
claims, damages, liabilities and related expenses, including reasonable counsel
fees, charges and disbursements, incurred by or asserted against any Indemnitee
arising out of, in any way connected with, or as a result of (i) the execution
or delivery of this Agreement or any other Loan Document or any agreement or
instrument contemplated hereby or thereby, the performance by the parties
hereto or thereto of their respective obligations hereunder or thereunder or
the consummation of the Transactions and the other transactions contemplated
hereby or thereby, (ii) the use of the proceeds of the Loans or issuance of
Letters of Credit, (iii) any claim, litigation, investigation or proceeding
relating to any of the foregoing, whether or not any Indemnitee is a party
thereto, or (iv) any actual or alleged presence or Release of Hazardous
Materials on any property currently or formerly owned or operated by Polypore
or any of the Subsidiaries, or any Environmental Liability related in any way
to Polypore or the Subsidiaries; provided, that such indemnity shall
not, as to any Indemnitee, be available to the extent that such losses, claims,
damages, liabilities or related expenses are determined by a court of competent
jurisdiction by final and nonappealable judgment to have resulted from the
gross negligence or willful misconduct of such Indemnitee or for a breach of the Loan Documents by such
Indemnitee.

(c)                                  To
the extent that Holdings and Polypore fail to pay any amount required to be
paid by them to the Administrative Agent, the Issuing Bank or the Swingline
Lender under paragraph (a) or (b) of this Section, each Lender severally agrees
to pay to the Administrative Agent, the Issuing Bank or the Swingline Lender, as
the case may be, such Lender’s pro rata share (determined as of the time that
the applicable unreimbursed expense or indemnity payment is sought) of such
unpaid amount; provided, that the unreimbursed expense or indemnified
loss, claim, damage, liability or related expense, as the case may be, was
incurred by or asserted against the Administrative Agent, the Issuing Bank or
the Swingline Lender in its capacity as such. 
For purposes hereof, a Lender’s “pro rata share” shall be determined
based upon its share of the sum of the Aggregate Revolving Credit Exposure,
outstanding Term Loans and unused Commitments at the time.

(d)                                 To
the extent permitted by applicable law, neither Holdings nor Polypore shall
assert, and each hereby waives, any claim against any Indemnitee, on any theory
of liability, for special, indirect, consequential or punitive damages (as
opposed to direct or actual damages) arising out of, in connection with, or as
a result of, this Agreement or any agreement or instrument contemplated hereby,
the Transactions, any Loan or Letter of Credit or the use of the proceeds
thereof.

(e)                                  The
provisions of this Section 9.5 shall remain operative and in full force and
effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of any of
the Loans, the expiration of the Commitments, the expiration of any Letter of
Credit, the invalidity or unenforceability of any term or provision of this
Agreement or any other Loan Document, or any investigation made by or on behalf
of the Administrative Agent, any Lender or the Issuing Bank.  All amounts due under this Section 9.5 shall
be payable on written demand therefor.

SECTION
9.6.  Right of Setoff.  If an Event of Default shall have occurred
and be continuing, each Lender is hereby authorized at any time and from time
to time, except to the extent prohibited by law, to set off and apply any and
all deposits (general or special, time or demand, provisional or final) at any
time held and other indebtedness at any time owing by such Lender to or for the
credit or the account of Polypore, Daramic Holding or Holdings against any of
and all the obligations of Polypore, Daramic Holding or Holdings now or
hereafter existing under this Agreement and other Loan Documents held by such
Lender, irrespective of whether or not such Lender shall have made any demand
under this Agreement or such other Loan Document and although such obligations
may be unmatured.  The rights of each
Lender under this Section 9.6 are in addition to other rights and remedies
(including other rights of setoff) which such Lender may have.

 90
 

SECTION
9.7.  Applicable Law.  THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS
(OTHER THAN LETTERS OF CREDIT AND AS EXPRESSLY SET FORTH IN OTHER LOAN
DOCUMENTS) SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF
THE STATE OF NEW YORK.  EACH LETTER OF
CREDIT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED IN ACCORDANCE WITH, THE
LAWS OR RULES DESIGNATED IN SUCH LETTER OF CREDIT, OR IF NO SUCH LAWS OR RULES
ARE DESIGNATED, THE UNIFORM CUSTOMS AND PRACTICE FOR DOCUMENTARY CREDITS MOST
RECENTLY PUBLISHED AND IN EFFECT, ON THE DATE SUCH LETTER OF CREDIT WAS ISSUED,
BY THE INTERNATIONAL CHAMBER OF COMMERCE (THE “UNIFORM CUSTOMS”) AND, AS
TO MATTERS NOT GOVERNED BY THE UNIFORM CUSTOMS, THE LAWS OF THE STATE OF NEW
YORK.

SECTION
9.8.  Waivers; Amendment.  (a)  No
failure or delay of the Administrative Agent, any Lender or the Issuing Bank in
exercising any power or right hereunder or under any other Loan Document shall
operate as a waiver thereof, nor shall any single or partial exercise of any
such right or power, or any abandonment or discontinuance of steps to enforce
such a right or power, preclude any other or further exercise thereof or the
exercise of any other right or power. 
The rights and remedies of the Administrative Agent, the Issuing Bank
and the Lenders hereunder and under the other Loan Documents are cumulative and
are not exclusive of any rights or remedies that they would otherwise
have.  No waiver of any provision of this
Agreement or any other Loan Document or consent to any departure by Polypore or
any other Loan Party therefrom shall in any event be effective unless the same
shall be permitted by paragraph (b) below, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given.  No notice or demand on Polypore,
Daramic Holding or Holdings in any case shall entitle Polypore, Daramic Holding
or Holdings to any other or further notice or demand in similar or other
circumstances.

(b)                                 Neither
this Agreement nor any of the Security Documents nor any provision hereof or
thereof may be waived, amended or modified except pursuant to an agreement or
agreements in writing entered into by Polypore, Holdings, the Required Lenders
and, if directly affected thereby, Daramic Holding; provided, however, that (w) Polypore,
Holdings and the Administrative Agent may enter into an amendment to effect the
provisions of Section 2.23(b) upon the effectiveness of any Incremental Term
Loan Assumption Agreement (and any such amendment shall in any event be deemed
to have occurred upon such effectiveness); (x) no such agreement under this
Section 9.8(b) shall (i) decrease the principal amount of, or extend the
maturity of or any scheduled principal payment date or date for the payment of
any interest on any Loan or any date for reimbursement of an L/C Disbursement,
or waive or excuse any such payment or any part thereof, or decrease the rate
of interest on any Loan or L/C Disbursement, without the prior written consent
of each Lender directly affected thereby, (ii) increase or extend the
Commitment or decrease or extend the date for payment of any Fees of or any
other amount actually due and payable hereunder to any Lender without the prior
written consent of such Lender, (iii) amend or modify the pro rata requirements
of Section 2.16, the provisions of this Section 9.8, or release any Guarantor
or all or substantially all of the Collateral, without the prior written
consent of each Lender directly affected thereby, (iv) change the provisions of
any Loan Document in a manner that by its terms adversely affects the rights in
respect of payments due to Lenders holding Loans of one Class differently from
the rights of Lenders holding Loans of any other Class without the prior
written consent of Lenders holding a majority in interest of the outstanding
Loans and unused Commitments of each adversely affected Class, (v) amend,
modify or waive compliance by Holdings or Polypore with the provisions of
Section 4.1, as it relates to an Event of Default following a breach of any
provision of this Agreement without the prior written consent of the Required
Revolving Lenders, (vi) reduce the percentage contained in the definition of
the term “Required Lenders” without the prior written consent of each Lender or
reduce the percentage contained in the definition of the term “Required
Revolving Lenders” without the prior written consent of each Revolving Credit
Lender (it being understood that with the consent of the

 91
 

Required
Lenders, additional extensions of credit pursuant to this Agreement may be
included in the determination of the Required Lenders on substantially the same
basis as the Term Loan Commitments and Revolving Credit Commitments on the
Restatement Effective Date) or (vii) without the prior written consent of each
Lender directly affected thereby, amend the definition of the term “Interest
Period” in any way which would permit Interest Periods to be in excess of six
months without regard to availability to Lenders; (y) amendments, waivers and
other modifications may be made to Sections 6.10, 6.11 and the last two
paragraphs of Article VII with only the written consent of the Required
Revolving Lenders (unless an Event of Default under Section 6.10 or 6.11 has
occurred with respect to the Term Facility as provided in paragraph (d) of
Article VII, in which case this clause (y) shall cease to apply in respect of
such Event of Default); and (z) amendments, waivers and other modifications to
the definition of “Total Leverage Ratio” shall not affect the determination of
the Applicable Percentage for the Revolving Facility or the Term Loans without
the prior written consent of the Required Revolving Lenders or the holders of
more than 50% of the aggregate unpaid principal amount of the affected Term
Loans then outstanding, respectively; provided, further, that no such agreement shall amend, modify or otherwise affect
the rights or duties of the Administrative Agent, the Issuing Bank or the
Swingline Lender hereunder or under any other Loan Document without the prior
written consent of the Administrative Agent, the Issuing Bank or the Swingline
Lender.  Notwithstanding anything to the
contrary herein, no Defaulting Lender shall have any right to approve or
disapprove any amendment, waiver or consent hereunder, except that the
Commitment of such Lender may not be increased or extended without the consent
of such Lender (it being understood that any Commitments or Loans held or
deemed held by any Defaulting Lender shall be excluded for a vote of the
Lenders hereunder requiring any consent of the Lenders).

SECTION
9.9.  Interest Rate Limitation.  Notwithstanding anything herein to the
contrary, if at any time the interest rate applicable to any Loan or
participation in any L/C Disbursement, together with all fees, charges and
other amounts which are treated as interest on such Loan or participation in
such L/C Disbursement under applicable law (collectively the “Charges”),
shall exceed the maximum lawful rate (the “Maximum Rate”) which may be
contracted for, charged, taken, received or reserved by the Lender holding such
Loan or participation in accordance with applicable law, the rate of interest
payable in respect of such Loan or participation hereunder, together with all
Charges payable in respect thereof, shall be limited to the Maximum Rate and,
to the extent lawful, the interest and Charges that would have been payable in
respect of such Loan or participation but were not payable as a result of the
operation of this Section 9.9 shall be cumulated and the interest and Charges
payable to such Lender in respect of other Loans or participations or periods
shall be increased (but not above the Maximum Rate therefor) until such cumulated
amount, together with interest thereon at the Federal Funds Effective Rate to
the date of repayment, shall have been received by such Lender.

SECTION
9.10.  Entire Agreement.  This Agreement, the Fee Letter and the other
Loan Documents constitute the entire contract between the parties relative to
the subject matter hereof.  Any other
previous agreement among the parties with respect to the subject matter hereof
is superseded by this Agreement and the other Loan Documents.  Nothing in this Agreement or in the other
Loan Documents, expressed or implied, is intended to confer upon any Person
(other than the parties hereto and thereto, their respective successors and
assigns permitted hereunder (including any Affiliate of the Issuing Bank that
issues any Letter of Credit) and, to the extent expressly contemplated hereby,
the Related Parties of each of the Administrative Agent, the Issuing Bank and
the Lenders) any rights, remedies, obligations or liabilities under or by
reason of this Agreement or the other Loan Documents.

SECTION
9.11.  WAIVER OF JURY TRIAL.  EACH PARTY HERETO HEREBY WAIVES, TO THE
FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY
JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS.  EACH PARTY HERETO (A) CERTIFIES THAT NO
REPRESENTATIVE, AGENT

 92
 

OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED,
EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT
AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND
THE OTHER LOAN DOCUMENTS, AS APPLICABLE, BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS IN THIS SECTION 9.11.

SECTION
9.12.  Severability.  In the event any one or more of the
provisions contained in this Agreement or in any other Loan Document should be
held invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein and therein
shall not in any way be affected or impaired thereby (it being understood that
the invalidity of a particular provision in a particular jurisdiction shall not
in and of itself affect the validity of such provision in any other
jurisdiction).  The parties shall
endeavor in good-faith negotiations to replace the invalid, illegal or
unenforceable provisions with valid provisions the economic effect of which
comes as close as possible to that of the invalid, illegal or unenforceable
provisions.

SECTION
9.13.  Counterparts.  This Agreement may be executed in
counterparts (and by different parties hereto on different counterparts), each
of which shall constitute an original but all of which when taken together
shall constitute a single contract, and shall become effective as provided in
Section 9.3.  Delivery of an executed
signature page to this Agreement by facsimile transmission shall be as
effective as delivery of a manually signed counterpart of this Agreement.

SECTION
9.14.  Headings.  Article and Section headings and the Table of
Contents used herein are for convenience of reference only, are not part of
this Agreement and are not to affect the construction of, or to be taken into
consideration in interpreting, this Agreement.

SECTION
9.15.  Jurisdiction; Consent to
Service of Process. 
(a)  Each of Holdings, Polypore
and Daramic Holding hereby irrevocably and unconditionally submits, for itself
and its property, to the nonexclusive jurisdiction of any New York State court
or Federal court of the United States of America sitting in New York City, and
any appellate court from any thereof, in any action or proceeding arising out
of or relating to this Agreement or the other Loan Documents, or for
recognition or enforcement of any judgment, and each of the parties hereto
hereby irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in such New York State
or, to the extent permitted by law, in such Federal court.  Each of the parties hereto agrees that a
final judgment in any such action or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law.  Nothing in this
Agreement shall affect any right that the Administrative Agent, the Issuing
Bank or any Lender may otherwise have to bring any action or proceeding
relating to this Agreement or the other Loan Documents against Polypore,
Daramic Holding, Holdings or their respective properties in the courts of any
jurisdiction.

(b)                                 Each
of Holdings, Polypore and Daramic Holding hereby irrevocably and
unconditionally waives, to the fullest extent it may legally and effectively do
so, any objection which it may now or hereafter have to the laying of venue of
any suit, action or proceeding arising out of or relating to this Agreement or
the other Loan Documents in any New York State or Federal court.  Each of the parties hereto hereby irrevocably
waives, to the fullest extent permitted by law, the defense of an inconvenient
forum to the maintenance of such action or proceeding in any such court.

(c)                                  Each
of Holdings, Polypore and Daramic Holding irrevocably consents to service of
process in the manner provided for notices in Section 9.1.  Nothing in this Agreement will affect the
right of any party to this Agreement to serve process in any other manner
permitted by law.

 93
 

SECTION
9.16.  Confidentiality.  Each of the Administrative Agent, the Issuing
Bank and the Lenders agrees to maintain the confidentiality of the Information
(as defined below), except that Information may be disclosed (i) to its and its
Affiliates’ officers, directors, employees and agents, including accountants,
legal counsel and other advisors (it being understood that the Persons to whom
such disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential), (ii) to the
extent requested by any regulatory authority or quasi-regulatory authority
(such as the National Association of Insurance Commissioners), (iii) to the
extent required by applicable laws or regulations or by any subpoena or similar
legal process, (iv) in connection with the exercise of any remedies hereunder
or under the other Loan Documents or any suit, action or proceeding relating to
the enforcement of its rights hereunder or thereunder, (v) subject to an
agreement containing provisions substantially the same as those of this
Section 9.16, to (A) any actual or prospective assignee or pledgee of
or participant in any of its rights or obligations under this Agreement and the
other Loan Documents or (B) any actual or prospective counterparty (or its
advisors) to any swap or derivative transaction relating to Polypore or any
Subsidiary or any of their respective obligations, (vi) with the consent
of Polypore or (vii) to the extent such Information becomes publicly
available other than as a result of a breach of this Section 9.16.  For the purposes of this Section, “Information”
shall mean all information received from Polypore or Holdings and related to
Polypore or Holdings or their business, other than any such information that
was available to the Administrative Agent, the Issuing Bank or any Lender on a
nonconfidential basis prior to its disclosure by Polypore or Holdings; provided
that, in the case of Information received from Polypore or Holdings after the
Restatement Effective Date, such information is clearly identified at the time
of delivery as confidential.  Any Person
required to maintain the confidentiality of Information as provided in this
Section 9.16 shall be considered to have complied with its obligation to do so
if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord its own
confidential information.

Each Lender acknowledges
that information furnished to it pursuant to this Agreement or the other Loan
Documents may include material non-public information concerning Polypore and
its Affiliates and their related parties or their respective securities, and
confirms that it has developed compliance procedures regarding the use of
material non-public information and that it will handle such material
non-public information in accordance with those procedures and applicable law,
including Federal and state securities laws.

All information, including
requests for waivers and amendments, furnished by any Loan Party or the
Administrative Agent pursuant to, or in the course of administering, this
Agreement or the other Loan Documents will be syndicate-level information,
which may contain material non-public information about Polypore and its
Affiliates and their related parties or their respective securities.  Accordingly, each Lender represents to
Polypore and the Administrative Agent that it has identified in its
administrative questionnaire a credit contact who may receive information that
may contain material non-public information in accordance with its compliance
procedures and applicable law, including Federal and state securities laws.

SECTION
9.17.  USA Patriot Act.  Each
Lender hereby notifies the Borrower that pursuant to the requirements of the
USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001))
(the “Patriot Act”), it is required to obtain, verify and record
information that identifies the Borrower, which information includes the name
and address of the Borrower and other information that will allow such Lender
to identify the Borrower in accordance with the Act.

SECTION
9.18.  Releases of Guarantees
and Liens.  (a)
Notwithstanding anything to the contrary contained herein or in any other Loan
Document, the Administrative Agent is hereby irrevocably authorized by each
Lender (without requirement of notice to or consent of any Lender except as
expressly required by Section 9.8) to take any action requested by Polypore
having the effect of releasing any Collateral or guarantee

 94
 

obligations (i) to the extent necessary to permit
consummation of any transaction not prohibited by any Loan Document or that has
been consented to in accordance with Section 9.8 or (ii) under the
circumstances described in paragraph (b) below.

(b)  At such time as the Loans, the Reimbursement
Obligations and the other obligations under the Loan Documents (other than
obligations under or in respect of Hedging Agreements and Cash Management
Agreements) shall have been paid in full, the Commitments have been terminated
and no Letters of Credit shall be outstanding, the Collateral shall be released
from the Liens created by the Security Documents, and the Security Documents
and all obligations (other than those expressly stated to survive such
termination) of the Administrative Agent and each Loan Party under the Security
Documents shall terminate, all without delivery of any instrument or
performance of any act by any Person.

SECTION
9.19.  Judgment Currency.  (a) The Borrower’s obligations hereunder and
under the other Loan Documents to make payments in a specified currency (the “Obligation
Currency”) shall not be discharged or satisfied by any tender or recovery
pursuant to any judgment expressed in or converted into any currency other than
the Obligation Currency, except to the extent that such tender or recovery
results in the effective receipt by the Administrative Agent or a Lender of the
full amount of the Obligation Currency expressed to be payable to the
Administrative Agent or such Lender under this Agreement or the other Loan
Documents.  If, for the purpose of
obtaining or enforcing judgment against any Loan Party in any court or in any
jurisdiction, it becomes necessary to convert into or from any currency other
than the Obligation Currency (such other currency being hereinafter referred to
as the “Judgment Currency”) an amount due in the Obligation Currency,
the conversion shall be made, at the rate of exchange (as quoted by the
Administrative Agent or if the Administrative Agent does not quote a rate of
exchange on such currency, by a known dealer in such currency designated by the
Administrative Agent) determined, in each case, as of the Business Day
immediately preceding the date on which the judgment is given (such Business
Day being hereinafter referred to as the “Judgment Currency Conversion Date”).

(b)  If there is a change in the rate of exchange
prevailing between the Judgment Currency Conversion Date and the date of actual
payment of the amount due, the Borrower covenants and agrees to pay, or cause
to be paid, such additional amounts, if any (but in any event not a lesser
amount), as may be necessary to ensure that the amount paid in the Judgment
Currency, when converted at the rate of exchange prevailing on the date of
payment, will produce the amount of the Obligation Currency which could have
been purchased with the amount of Judgment Currency stipulated in the judgment
or judicial award at the rate of exchange prevailing on the Judgment Currency
Conversion Date.

(c)  For purposes of determining any rate of
exchange or currency equivalent for this Section, such amounts shall include
any premium and costs payable in connection with the purchase of the Obligation
Currency.

SECTION 9.20.   Taux
Effectif Global.   In order to comply with
the provisions of Articles L. 313-4 and L. 313-5 of the French Code monétaire et
financier, the effective global rate (“taux effectif global”) calculated in
accordance with the articles referred to above is as set out in a letter dated
the date of this Agreement from the Original Lenders to Daramic Holding
substantially in the form of Exhibit H. Such rate is given on an indicative
basis and shall not be binding on the Lenders in the future.
