this Consent Decree

is made

by and between

the United States

of America,

at the request

and
on behalf

of the Administratorof

the United States Environmental Protection Agency (“EPA”),

the State

of Delaware Department

of Natural Resources

and Environmental Control,

the South Carolina Department

of Health

& Environmental
Control,

the Chattanooga- Hamilton County

Air Pollution Control Board (collectively “Plaintiffs”)

and IN VISTA

S.à
r.l (“INVISTA”). Whereas, Plaintiffs,

by and through
their undersigned counsel,
have simultaneously

filed Complaints

and lodged

this Consent Decree against INVISTA. Whereas,

IN VISTA

is

a privately-owned
integrated
fibers
and polymers company registered

as

a foreign limited liability company

in the State

of Delaware

and headquartered

in Wichita, Kansas. Whereas,

on April

30, 2004 (the “Closing Date”),

E.I.
du Pont

de Nemours

and Company and INVISTA finalized

the sale
of the DuPont Textiles

& Interiors assets

to INVISTA

S.à r.l. The transaction involved

over forty sites worldwide. Twelve facilities
were located

in the United States, specifically

at: Athens,

GA; Calhoun,

GA; Camden,

SC; Chattanooga,

TN; Dalton,

GA; Kinston,

NC; LaPorte,

TX; Martinsville,

VA; Orange,

TX; Seaford,

DE; Victoria,

TX; and Waynesboro,

VA (“Acquired Facilities”). Whereas,

EPA recognizes

the critical

role
of environmental
auditing

in protecting human health

and the environment

by identif’ing, correcting,

and ultimately preventing violations

of environmental

laws, particularly

by responsible corporate citizens

and new owners. Whereas,

as

a result

of the identification

and disclosure

of certain pre-Closing

Date environmental noncompliance

existing

at some

of the Acquired Facilities, INVISTA

and EPA

in July and August
2004 agreed
that, pursuant

to EPA’s Policy

on Incentives

for Self-Policing: Discovery, Disclosure, Correction,

and Prevention

of Violations,

65 Fed. Reg. 19618 (Apr.

11, 2000) (“EPA’s Audit Policy”),

IN VISTA would continue implementation

of its Compliance Assurance Management
System (“CAMS”)

and conduct audits

at the Acquired Facilities (hereinafter referred

to as the “Corporate

Audit Agreement”).

In order

to avail itself

of the benefits afforded under EPA’s Audit Policy,

IN VISTA entered

into the Corporate
Audit Agreement

and was required thereunder

to complete environmental compliance

audits

in addition

to continued implementation

of its CAMS

at the Acquired Facilities covering

the following statutes

and implementing regulations thereof, corresponding

state

or local laws and regulations,

and any permits issued under these laws (hereinafter referred

to collectively

as “Environmental Requirements”):

the Emergency Planning

and Community Right-to-Know

Act (EPCRA),

42 U.S.C.

§ 11001

to 11050;

the Clean Water Act(CWA),

42 U.S.C.

§ 1251

to 1387;

the Resource Conservation

and Recovery

Act (RCRA),

42 U.S.C.

§ 6901

to 6992k;

the Federal Insecticide, Fungicide,

and Rodenticide

Act (FIFRA),

7 U.S.C.

§ 136

to l36y; Section 103(a)

of the Comprehensive Environmental Response, Compensation,

and Liability

Act (CERCLA),

42 U.S.C.

§ 9603(a);

the Safe Drinking Water
Act (SDWA),

42 U.S.C.

§ 300f

to 300j-26;

and the Clean
Air Act (CAA),

42 U.S.C.

§ 7401

to 7671q. 1Whereas,

over
the course

of 33 months, INVISTA conducted

23 comprehensive

and
22 focused environmental

audits examining

the pie- and post-Closing

I)ate compliance

of the Acquired Facilities

with
the Environmental Requirements.

During

and upon completion

of those audits, consistent

with EPA’s Audit Policy, INVISTA timely disclosed

the violations identified in Appendices

A, B, and

C. Whereas

for the findings contained

in Appendices

A, B, and

C, the Plaintiffs performed reviews

of INVISTA’s quarterly

and final reports submitted pursuant

to the Corporate
Audit Agreement,

which detailed

the auditors’ factual, technical,

and legal findings.

The Plaintiffs’ review
also included

site visits

to three Acquired Facilities

that were related

to the findings

of violation

and consideration

of appropriate remedies,

a series

of technical meetings,

legal and technical correspondence regarding

the findings

of violations

and consideration

of appropriate remedies, supplemental information requests,

and

a review

of information

and site-specific

data submitted

by INVISTA

in response

to Plaintiffs’ requests.
After that review

the Plaintiffs determined,

based

on the foregoing,

that violations

of Environmental Requirements

had occurred as set forth

in Appendices

A, B, and

C. Whereas,
based upon
the results

of those audits,

the United States alleges

that violations of Environmental Requirements

have taken place

at IN VISTA’s Acquired Facilities

as set forth in Appendices

A, B, and

C, and that
IN VISTA

has certified

that
all violations

in Appendix

A have been corrected. Whereas,

due

to significant complexities requiring further investigation, analysis,

and potential corrective actions, INVISTA

and EPA have agreed

tO resolve RCRA

and CWA disclosures pertaining

to the wastewater treatment

and conveyance systems

at INVISTA’s LaPorte, Orange,

and Victoria-facilities

in

a future agreement,

if necessary,

with the understanding

that this Consent Decree
shall not prevent
such disclosures

from receiving coverage under EPA’s Audit Policy. Whereas,
based

on the representations

by INVISTA,

EPA
has determined

that the violations

as set forth

in Appendices

A, B, and

C have met the conditions

of EPA’s Audit Policy and are appropriate

for resolution

in accordance

with
the Policy. Whereas,
based upon
the results

of the audits,

the United States,

the State

of Delaware Department

of Natural Resources

and Environmental
Control,

the South Carolina Department

of Health

& Environmental
Control,

and the Chattanooga-Hamilton

County

Air Pollution Control Board allege
that violations

of certain Clean

Air Act programs

and their implementing

federal, state, and/or local regulations

have been and/or

are continuing

to take place

at certain

of INVISTA’s Acquired Facilities, including:

the Nonattainment

New Source Review and/or Prevention

of Significant Deterioration programs (NNSRIPSD),

42 U.S.C.

§ 7412;
and Leak Detection

and Repair (LDAR) requirements

42 U.S.C.

§ 7411-7412. Whereas,

the Plaintiffs

and
IN VISTA
wish

to resolve

the violations

of Environmental Requirements

that
IN VISTA

has already corrected

or

is required

to correct under
this Decree

by 2 q)-..— .-. —

that SCR

is not feasible,

as defined

in Subparagraph

18.i,

to treat combined liquid/gas wastes

at the Victoria Boilers,

and EPA agrees pursuant

to Subparagraph

18.j, IN VISTA may,

at any time after December

31, 2012, re-route

the Low Boiler Waste streams
from Boiler(s)

7 and/or

in accordance

with optimum operating parameters

for minimizing

NO emissions

that were identified during

the Optimization

Period

for Boilers

7 and/or

8 under Subparagraph 21.a. “Feasibility” Determination.

For purposes

of this Paragraph,

the feasibility

of SCR shall

be determined

based only

on the following criteria: If the data collected during

the Study indicate

that the catalyst

in

a fulL-scale

SCR
for the relevant liquid/gas

or,
as applicable,

gasonly boiler would need

to be replaced

at

a rate
of more than once per 12-month period

in order

to maintain

a NO removal efficiency greater
than that
of SNCR,
then SCR

is considered infeasible

for the purpose

of this Paragraph

18; ii.

If the data collected during

the Study indicate

that

a full-scale

SCR for the relevant liquid/gas

or,
as applicable, gas-nly boiler would require space velocity

of less than 7,000 hf’, then SCR

is considered infeasible

for the purpose

of this Paragraph

18; or iii.

If the data collected during

the Study indicate

that the amount

of catalyst required

in

a fuH-scale

SCR
for the relevant liquid/gas

or, as applicable, gas-only boiler would create

a back pressure

that exceeds

the current structurallmechanical

limitations

of the boiler, then SCR

is considered infeasible

for the purpose

that INVISTA intends

to place

on the “delay

of repair”

list, under applicable regulations: i. TNVISTA

shall require sign-off

by the unit supervisor within thirty (30) days

of identif’ing

that

a piece

of equipment

is leaking

at

a rate greater
than the applicable

leak definition

and that such equipment qualifies

for delayed repair under applicable regulations; ii.

IN VISTA
shall include equipment

that

is placed

on the “delay

of repair”

list

in IN VISTA’s regular LDAR monitoring; iii. INVISTA

shall use

its best efforts

to isolate

and repair centrifugal pumps identi fled

as leaking

at

a rate
of 2,000 ppm

or greater;

and iv. Beginning

no later than
six (6) months
from the Date

of Lodging of the Consent Decree,

on valves subject

to the LDAR Regulations,

other than control valves

and pressure relief valves, that are leaking

at

a rate
of 10,000 ppm

or greater, INVISTA

will use

a “drill and tap”

or equivalent method

for fixing such leaking valves, unless INVISTA

can demonstrate

that there

is

a safety, mechanical,

or adverse environmental
concern posed

by attempting to repair

the leak

in this manner. INVISTA

will perform

the first “drill
and tap”
(or equivalent
repair method) within fifteen
(15) days,
and

a second attempt

(if necessary)
within thirty (30) days after
the leak

is detected.

If

a new method develops

for repairing such valves,

IN VISTA

will advise EPA prior

to implementing

the use of such new method

in place

of drill and tap for repairs required under
this Decree. 78. Chronic Leakers.

A valve shall

be classified

as

a “chronic leaker” under
this Paragraph

if
it leaks above 5,000 ppm twice

in any consecutive

four
(4) quarters

after the Entry Date, unless

the valve
has not leaked

in the twelve
(12) consecutive quarters
prior

to the relevant process

unit turnaround. Following

the identification

of

a “chronic leaker” non-control

valve, TN VISTA
shall replace, repack,

or perform similarly effective repairs

on the chronic leaker during

the next process

unit turnaround. 79. Alternate

a result

of dispute resolution. INVISTA

shall

be liable

for stipulated penalties

for its failure thereafter

to complete

the work

with the extended

or modified schedule.: 119.
The Court shall decide

all disputes pursuant

to applicable principles

of law for resolving

such disputes.

In their initial filings with the Court under Paragraph

116, the disputing Parties shall state their respective positions

as to the applicable standard

of law for resolving

the particular dispute. 120.
