1.0 Introduction

1.1 Purpose

The ability of businesses in the LANXESS Inc. Bio-Industrial Park Sarnia (hereinafter, “BPS” and/or the “BPS site”) to coexist when engaging in activities at the BPS site depends on a shared understanding of orderly cooperation and a shared commitment to the protection of the health and safety of individuals and the environment.

The businesses located within BPS operate in close physical proximity and are, for the most part, integrated to services provided by LANXESS Inc. (“LANXESS”), which acts as the manager and operator of BPS (the “BPS Operator”). Given these circumstances and the parties’ resultant responsibilities, the BPS Operator is responsible for enforcing these rules (hereinafter, the “Rules” or “BPS Rules”). The goal is to protect member businesses and people within and outside BPS from certain hazards and to provide everyone at BPS with an appropriate working environment.

All businesses operating at BPS, as well as their employees, contractors, agents and visitors, are required to comply with all applicable laws and regulations. It is in everyone’s interest to operate their businesses safely and in an environmentally responsible manner and to consider the needs of others. Without limiting the generality of the foregoing, in order to protect people and the environment, businesses located within BPS are encouraged to adhere to the Chemistry Industry Association of Canada’s Responsible Care ® concepts

These Rules set forth the essential topics required for orderly coexistence and good relations between the businesses located within BPS who are, on account of an agreement with LANXESS Inc, subject to these Rule (hereinafter referred to collectively as “Member businesses” and individually as a “Member business”).

These Rules are mandatory for each Member business and for everyone under its control. Each Member business is responsible for ensuring that its employees, contractors, agents and visitors are made aware of and comply with these Rules.

These Rules include the attached schedules and requirements based on statutory obligations and, if applicable, existing agreements between the BPS Operator and Member businesses.

1.2 Services

For greater certainty, these Rules do not commit the BPS Operator to provide any services to any Member businesses, including, without limitation, services related to emergency response, water treatment, security, etc.

The BPS Operator provides various services to Member businesses under the terms and conditions of separately negotiated service agreements. Therefore, in the event of any inconsistency between these Rules and the terms and conditions of any service agreement dealing specifically with the issue or service in question, the terms and condition of the service agreement shall prevail. Where no service agreement exists between the BPS Operator and a Member business for any service mentioned herein, the BPS Operator is under no obligation to provide, and will not provide, such service.

1.3 Modifications

The purpose of these Rules is to establish and communicate uniform rules applicable to all Member businesses for the orderly operation and management of BPS and for the protection of the environment, property and assets and the health and safety of individuals (hereinafter the “Rule Purposes”).

*Confidential Treatment Requested

- 41 -

Accordingly, the BPS Operator reserves the right to revise, amend, delete and add to these Rules from time to time at its discretion, acting reasonably. However, prior to doing so, the BPS Operator will provide Member businesses’ twenty-one (21) days to provide their input in writing on the suggested revisions, amendments, additions and/or deletions to the Rules. The BPS Operator will consider Members businesses’ input but ultimately reserves the exclusive right, acting reasonably, to revise, amend, delete, and add to these Rules, provided that such amendments are in keeping with the Rule Purposes. The BPS Operator undertakes to provide Member businesses thirty (30) days advance notice prior to enforcing such revisions, amendments, deletions and additions.

d) introduction of new chemicals;

e) material change to the source(s) or nature of discharges or emissions to the environment; or

f) material change to the nature or location of any facilities, operations or activities;

on its site, each Member business shall provide the BPS Operator with written notice of such planned activity(ies), detailed layout, hazard and operability plans for such activity(ies) and a reasonable opportunity to comment on any health, safety and/or environmental issues arising from such planned activity(ies). Such notice shall include a detailed description of the planned activity(ies) as well as, if applicable, a listing of hazardous and flammable materials.

If the BPS Operator is not satisfied with the Member business’ planned activity(ies) due to concern that the proposed activity(ies) would impose a significant risk of Material Offsite Impact(s), the BPS Operator will advise the Member business of its concerns within thirty (30) days of its receipt of the aforementioned plans. The Member business shall provide a written response to the BPS Operator’s concerns within fifteen (15) days of receiving such concerns, and if, on the basis of Reasonable Professional Judgment, any changes sought by the BPS Operator and / or any other changes are reasonably necessary to ensure that no Material Offsite Impact is caused by the planned activity(ies), the Member business shall make such changes to its plans. If the Member business does not make such changes to its plans and proceeds with its planned activity(ies) contrary to the provisions of these Rules, the BPS Operator reserves the right to seek damages and, where damages would be inadequate due to the nature of the activity in question, seek injunctive relief to prohibit such activity(ies).

If there is a material risk that a Member business’ proposed activity(ies) could have an adverse impact on another Member business’ property, assets and/or personnel, the Member business shall also notify the other Member business and allow that business the opportunity to provide input on any health, safety and/or environmental issues of interest to it.

Prior to the disclosure of any confidential information for these purposes, a Member business and/or the BPS Operator may, as the case may be, require that an appropriate written confidentiality undertaking be executed between the parties.

Each Member business acknowledges and agrees that any of the aforementioned activities are its own, sole responsibility and that no review of such activity by the BPS Operator shall result in any loss, damages or liability to the BPS Operator, nor shall such review reduce the responsibility and obligations of the Member business arising from or in connection with its activity.

Each Member business is also asked to provide the BPS Operator with copies of any environmental applications and building permit applications. In the event of a new construction and/or expansion of a building/facility, the Member business and the BPS Operator shall, where applicable, discuss any impact of the activity on existing alarms and emergency response protocols.

3.3 Environmental Air Emissions Modeling and Coordination

The BPS Operator and Member businesses engage in activities requiring certain air emission approvals from governmental authorities, including the Ontario Ministry of Environment.

11.4 Utilities Emergency Steam & Electrical Load Shedding Schedule

11.4.1 TransAlta Steam Emergency Procedure

These are the four (4) states of operation pertaining to the supply of steam, each of which are described below.

The four states of operations are as follows:

i) N-1 and Stable

Under this state of operation, the TransAlta steam distribution system is stable. No communication to customers is required. However, each Member business is required to notify the BPS Operator’s Shift Engineer (“BPS Shift Engineer”) of any significant load changes in their consumption of steam.

ii) N-1 Lost or Steam Supply is Unstable

When TransAlta has lost N-1 reliability or operations are unstable or at risk, the Member businesses will be notified at the time of occurrence and at the beginning of every shift until the situation is over. No action is required by the Member business; however, each Member business must always notify the BPS Shift Engineer of any significant load changes in its consumption of steam.

*Confidential Treatment Requested

- 58 -

iii) STEP ONE STEAM EMERGENCY

This step occurs after TransAlta’s condensing steam turbine (TG861A/B) load has already been minimized or is shutdown and TransAlta’s 1400# header pressure is at 1000 psi and falling. The Member business will be notified and advised that “TransAlta is having a Step 1 Emergency, please take appropriate action.” The BPS Shift Engineer will notify the Member business when a Step 1 is cancelled. At a minimum, the BPS Shift Engineer will provide an update the Member businesses at the beginning of every shift until the emergency is over.

iv) STEP TWO STEAM EMERGENCY

In this situation, TransAlta has had significant failure and cannot maintain its 475# header. Each Member business will be notified and advised of the following:

“TransAlta is having a Step 2 Emergency, we will notify you as soon as it is over.” Each Member business shall begin shutdown of its steam-consuming units, or prepare for loss of steam supply, upon being provided such notice.

Definitions

“N-1 Reliability” means, with respect to TransAlta’s steam generation facilities, operating such facilities such that total firm customer steam load being supplied by such facilities at that time could be supplied by the remaining on-line steam capacity if the largest single steam generator was lost.

Emergency Communications

In the event of an emergency related to steam, Member businesses are asked to contact the BPS Operator by dialing 519-337-8251, extension 4272 (BPS Main Gate). Indicate the nature of your emergency to the BPS Plant Protection and they will put you in contact with the BPS Shift Engineer.

To facilitate emergency communications, Member businesses are invited to install in their own facilities, and preferably in their control rooms, a wireless emergency public announcement connected to the BPS Operator’s public announcement system. Member businesses wishing to do so are invited to contact the BPS Operator.

In the event of a Step One or Two Steam emergency, the BPS Shift Engineer, after notification from TransAlta Energy Corporation (“TransAlta”), will determine when the emergency step is over. Such communications with each Member business receiving steam under a separately negotiated service agreement shall be recorded and shall include the name of the Member business contact, what was said and the time the call was made. Each Member business is required to maintain communication with the BPS Shift Engineer throughout the situation and, in particular, is required to inform the BPS Shift Engineer when its steam consumption rates are interrupted or reduced for any reason and for any amount of time.

Steam Procedures Prior to Take

Prior to a Member business drawing steam for the first time, the Member business shall have established a contingency plan addressing situations where its steam consumption quantities are reduced for any reason and shall have entered into an understanding with the BPS Operator with respect to the amount the Member business may safely reduce its steam consumption and the timing to effect such reduction in the event of a Step One and Step Two Emergency.

General Communications

All communications pertaining to the supply (including interruption) of steam are to be made between the BPS Shift Engineer and the Member business.

11.4.2 Electrical Emergency Shedding

Background

The BPS Operator may supply electricity to a Member business pursuant to the terms and conditions of a separately negotiated service agreement. In the event that the consumption of electricity needs to be reduced due to shortage of supply, an emergency, or for any other reason, the BPS Shift Engineer will contact the Member business and communicate to what degree, if any, the Member business’ electricity consumption must be reduced and by when, all in accordance with the BPS’ Site Electrical Emergency Procedure.

Prior to a Member business drawing electricity for the first time from the BPS Operator, the Member business shall have established a contingency plan addressing situations where electricity supply is reduced or eliminated and, secondly, shall have entered into an understanding with the BPS Operator with respect to the amount of electricity consumption the Member business may safely reduce and the timing to effect such reduction.

11.5 Excavation on BPS Property Schedule

1. Whenever a Member business is planning an excavation on the BPS site, it must first obtain the BPS Manager’s written permission to do so, and must comply with the BPS HES SOP 0030 Excavation Standard (“BPS Excavation Standard”). The BPS Manager will not grant such permission unless he or she is satisfied that the safety measures taken are appropriate in each case.

2. The Member business shall contact the BPS Manager prior to starting any excavations that might affect the BPS site. The BPS Excavation Standard is available from the BPS Manager and is designed to generally highlight the requirements of the regulations under the Occupational Health and Safety Act as they apply to excavation activities on the BPS site. Responsibility for the health and safety of any Member business’ worker remains, at all times, with the employing Member business.

3. The Member business shall ensure that all its employees and contractors comply with the BPS Excavation Standard.

4. Prior to initiating any excavation (e.g. digging) on the BPS site, the Member business will be required to obtain a Locate Report and Site Excavation Release form from the BPS Operator. These forms are described in the BPS Excavation Standard.

5. The Member business shall also be required to obtain utility locates. The BPS Operator’s Plant Engineering department (“BPS Plant Engineering”) is responsible to confirm through a drawing search that all drawings used for excavation work are the most current, and will work with the Member business’ staff to this end.

6. The Member business shall ensure that all necessary procedures are properly carried out for the safety of personnel working in and around the excavation(s), and so that services and utilities (piping, telephone, fiber optic, electrical cables, etc.) are not damaged.

7. The Member business shall ensure that the correct safe work permits are used for any work on the BPS site. The Member business shall contact the BPS Manager to obtain the proper permits by calling 519-337-8251, ext. 4569.

8. PAYMENT

8.1 Fee Structure

For the supply of Steam hereunder, BioAmber Sarnia shall pay LANXESS the following fees:

(a) Payment for Delivered Steam

For Steam delivered to BioAmber Sarnia under this Agreement, BioAmber Sarnia shall pay LANXESS, on a monthly basis, for its Monthly Steam Take in the Month, a fee, payable in Canadian dollars, calculated as follows:

MT x FCT x LCN = fee payable

in which,

“MT” is BioAmber Sarnia’s Monthly Steam Take, measured in MMBtu

“FCT” is [***]

“LCN” is the LANXESS Cost of Natural Gas for such Month

(hereinafter, the “Monthly Fee”)

*Confidential Treatment Requested

- 75 -

(b) Take or Pay Fee

In addition to the Monthly Fee or, where applicable, Gas Deposit (defined below) owing to LANXESS, for any Month that BioAmber Sarnia takes less than the applicable Monthly Minimum Steam Take, BioAmber Sarnia shall make a cash payment to LANXESS (“Monthly Take or Pay Fee”). This Monthly Take or Pay Fee shall be calculated as follows: (Monthly Minimum Steam Take - Monthly Steam Take)* [***]*Monthly Dawn.

After the end of each Year, this fee will be recomputed. If BioAmber Sarnia’s Annual Steam Take for the Year exceeds the Annual Minimum Steam Take, then all the Monthly Take or Pay Fee payments made by BioAmber Sarnia for the Months during that Year shall be refunded to BioAmber Sarnia. If BioAmber Sarnia’s Annual Steam Take for the Year is less than the Annual Minimum Steam Take, then an amount owing will be computed as follows: (Annual Minimum Steam Take - Annual Steam Take)* [***]*Annual Dawn. If this amount exceeds the sum of the Monthly Take or Pay Fee payments made by BioAmber Sarnia for Months during that Year, then BioAmber Sarnia shall pay such difference to LANXESS. If this amount is less than the sum of the Monthly Take or Pay Fee payments made by BioAmber Sarnia for Months during that Year, then LANXESS shall pay the difference to BioAmber Sarnia.

(c) Alternative Calculation to Monthly Fee

At BioAmber’s option, upon first providing LANXESS at least six (6) months of written advance notice, BioAmber Sarnia may opt to pay LANXESS in natural gas in lieu of the financial Monthly Fee for its Monthly Steam Take; and if BioAmber Sarnia elects to do so:

(i) As BioAmber Sarnia takes Steam hereunder, it shall, at no cost to LANXESS, deliver natural gas of the quality specified by the natural gas transporter on a pass through basis to the burner tip at TransAlta for LANXESS’ account at a natural gas to Steam multiplier of [***] MMBtu natural gas (HHV)/MMBtu Steam multiplied by BioAmber Sarnia’s actual Steam take (Net Enthalpy) (hereinafter, “Gas Deposit”);

(ii) BioAmber Sarnia shall provide LANXESS with written confirmation of such Gas Deposits to LANXESS’ reasonable satisfaction; and

(iii) At the end of each Month, all Gas Deposits made by BioAmber Sarnia in the Month shall be totaled (hereinafter, “Total Monthly Gas Deposits”). If BioAmber Sarnia’s Total Monthly Gas Deposits for the Month is less than the product of BioAmber Sarnia’s Monthly Steam Take x [***], then BioAmber Sarnia shall pay LANXESS an amount calculated as follows:

Amount payable =

DF x FCT x LCN

in which,

“DF” is the difference, measured in MMBTu, between: (i) BioAmber Sarnia’s Monthly Steam Take x [***]; and (ii) BioAmber Sarnia’s Total Monthly Gas Deposits

“FCT” is [***]

“LCN” is the LANXESS Cost of Natural Gas for such Month

15.2 Amount of Indemnification

(a) In the event that pursuant to this Section 15 either Party (herein referred to as the “Indemnitor”) is required to indemnify the other (herein referred to as the “Indemnitee”) the amount which the Indemnitor shall be required to pay to the Indemnitee with respect to any Claim shall be, subject to all other provisions of this Article 15, the full amount of such Claim and all costs or expenses incurred in defending or dealing with such Claim.

(b) The amount of any indemnification otherwise due pursuant to this Section 15 shall be net of the present value of any tax benefits associated with such Claim to:

(i) BioAmber Sarnia or its Affiliates, as the case may be; or

(ii) LANXESS or its Affiliates, as the case may be.

For the purposes of this Section 15.2, the present value with respect to any tax benefit associated with a Claim shall be calculated on the basis of the Canadian Prime Rate, in effect at the time at which the Indemnitor indemnifies the Indemnitee with respect to such Claim.

15.3 Notice of Claim

(a) Promptly upon the discovery by the lndemnitee of the existence of a Claim to which this Article 15 applies, the Indemnitee shall notify the Indemnitor in writing of such Claim setting out, to the extent reasonably feasible, full and detailed particulars of the Claim including, without limitation, the nature of and specific basis for such Claim and the estimated amount of such Claim (which estimate shall not be conclusive of the final amount of such Claim).

(b) The following provisions shall apply to any Claim relating to environmental indemnities:

(i) the Indemnitee shall, and shall cause its Affiliates to, permit the Indemnitor and its Affiliates to participate in any negotiations with any Governmental Authorities or to take any other proceedings with respect to Governmental Authorities which may be necessary, or which the Indemnitor may deem appropriate, with a view to minimizing the cost of satisfying the Claim. The Indemnitor will use reasonable efforts to minimize disruption of the Indemnitee’s ongoing operation of its business and the continuance of permits, approvals or licenses necessary to such operation; and

(ii) the lndemnitee shall give the Indemnitor and its Affiliates and their consultants reasonable access, upon reasonable advance notice, to its facilities from time to time to study soil, air and water qualities if such studies are viewed as appropriate by the Indemnitor for the purposes of verification or satisfaction of any Claim.

(c) In the event that the Indemnitee fails to give to the Indemnitor the notice required by this Section 15 with respect to any Claim then, to the extent that the Indemnitor is materially prejudiced by such failure, the obligation of the Indemnitor to indemnify the Indemnitee pursuant to this Section 15 shall cease with respect to such Claim.

(d) In the event that the Indemnitee refuses to deliver to the Indemnitor any books, records or other documentation reasonably required by the Indemnitor in order to defend any Claim in connection with which the lndemnitee is seeking indemnification pursuant to this Section 15 then to the extent that the lndemnitor is materially prejudiced by such refusal, the obligation of the lndemnitor to indemnify the Indemnitee pursuant to this Section 15 shall cease with respect to such Claim.

15.4 Contest by Indemnifying Party

(a) The lndemnitor shall at all times have the right (but not the obligation), at its sole expense and with counsel of its choice, to investigate, dispute and contest (in the name of the Indemnitee, where necessary) any Claim for which the lndemnitor admits its liability, or is found to be liable, pursuant to this Section 15.

(b) In the event that the lndemnitor shall retain counsel pursuant to this Section 15.4, the Indemnitee shall have the right to retain its own counsel to the extent such Claim has been asserted against it or its Affiliates, but the fees and expense of such counsel shall be at the expense of such Indemnitee.

(c) The Indemnitee will fully co-operate and shall cause its Affiliates and each of their respective auditors, accountants, counsel and other representatives to fully cooperate where necessary with the lndemnitor and its counsel in any proceedings with respect to any such Claim being contested by the lndemnitor pursuant to this Section 15.4. The Indemnitee shall afford to the lndemnitor reasonable access to such records of the Indemnitee as relate to such Claims and to such employees of the lndemnitee as have knowledge of the matters relating to such Claims.

15.5 Settlement of Third Party Claims

(a) In the event that a third party makes a Claim against the Indemnitee and the Indemnitee wishes to settle such Claim on terms which are acceptable to the claimant, the Indemnitee shall disclose to the lndemnitor all terms and conditions of the proposed settlement. If the lndemnitor does not consent in writing to the terms and conditions of such settlement, such consent not to be unreasonably withheld or delayed, the Indemnitee may thereafter settle such claim with the third party on terms no less favourable than the proposed settlement and the lndemnitor shall indemnify the Indemnitee to the extent that the Indemnitee establishes that such settlement was reasonable.

(b) In the event that a third party makes a Claim against the Indemnitee and the lndemnitor wishes to settle such Claim on terms which are acceptable to the claimant, the lndemnitor shall disclose to the Indemnitee all terms and conditions of the proposed settlement. If the lndemnitee does not wish to settle such Claim, the lndemnitor shall be required to indemnify the Indemnitee only up to the amount for which the lndemnitor could have settled the Claim, less those costs and expenses reasonably incurred by lndemnitor from and after the date on which the terms of the proposed settlement were disclosed by lndemnitor to lndemnitee. Such amount shall not exceed the amount which the Indemnitee pays in settlement of such third party Claim.

15.6 Coordination of Indemnification Rights

(a) In the event that an Indemnitee has a right of recovery against any third party with respect to any Claim in connection with which a payment is made to such Indemnitee by an Indemnitor then: (a) such Indemnitor shall, to the extent of such payment, be subrogated to all of the rights of recovery of such Indemnitee against such third party with respect to such Claim; and (b) such Indemnitee shall, at the Indemnitor’s request and expense, execute all papers reasonably required and take all reasonable action necessary to secure such rights, including, but not limited to, the execution of such documents as are reasonably necessary to enable such Indemnitor to bring suit to enforce such rights.

*Confidential Treatment Requested

- 85 -

(b) The Indemnitor in its sole discretion and upon notice to the Indemnitee may elect to set off any amount payable to the Indemnitee by the Indemnitor against any amount payable by the Indemnitee to the Indemnitor and the Indemnitee shall be indemnified in the manner provided in this Section 15.6 for any indemnifiable amount not covered by such set off.

15.7 Indemnitor May Cure

The Indemnitor shall have the right to cure within a reasonable time and in a manner satisfactory to the Indemnitee, acting reasonably, any matter giving rise to a Claim, provided however, that any such cure shall not relieve or reduce any such Claim arising prior to, during or because of such cure to the extent that such cure is inadequate.

16.1 General

LANXESS’ obligation to provide Steam hereunder shall be limited to using its reasonable efforts to do so and, subject to this obligation, LANXESS shall not be responsible to BioAmber Sarnia or others for any elimination, delay or reduction in the provision of Steam for any reason whatever save and except for the negligence of LANXESS and those for whom it is in law responsible.

If BioAmber Sarnia requests LANXESS to do so, LANXESS agrees to make reasonable efforts to pursue any reasonably available remedies against TransAlta arising from TransAlta’s failure to supply LANXESS with any Steam required hereunder and to provide BioAmber Sarnia with its proportionate share of any net benefit realized from pursuing such remedies, provided that BioAmber Sarnia fully cooperates with LANXESS in, and pays its proportionate share of the cost of, pursuing such remedies, and indemnifies LANXESS from any losses, costs or liabilities associated therewith.

Notwithstanding any provision of this Agreement, neither Party shall in any circumstances whatsoever be liable hereunder to the other Party for indirect, exemplary, special, incidental or consequential or punitive damages including, without limitation, any such damages for loss of profits sustained or claimed by the other Party in connection with or arising out of this Agreement; provided however that nothing herein shall in any way limit the right of a Party to be indemnified by the other Party pursuant to Section 15 for a claim to the extent that such Party is seeking indemnity for a third party Claim for incidental or consequential or punitive damages including, without limitation, loss of profits.

16.4 Right to Claim Damages

Subject to such limitations as are set forth in this Agreement, upon the occurrence of any breach of this Agreement by a Party, or any negligent act or omission by a Party

in the performance of this Agreement or the exercise of its rights under this Agreement, the other Party shall have the right to make a claim against the defaulting Party for any costs, losses, damages, liabilities, penalties or expenses the other Party has suffered or incurred as a result of such breach or negligence. All such claims must be submitted in writing to the defaulting Party within one-hundred and twenty (120) days of the day when the claiming Party knew or reasonably ought to have known of all the facts required to make the claim. Subject to the Parties’ indemnity obligations under Section 15 hereof, neither Party shall be liable to the other for any claim of any kind hereunder exceeding the total Monthly Fees of the Steam purchased hereunder in the six (6) Months prior to the date of such claim.

16.5 No Tortious Liability

A Party’s remedies in respect of any cost, losses, damages, liabilities, penalties or expense of whatsoever nature arising from any negligent act or omission by the other Party in the performance of its obligations or the exercise of its rights under this Agreement shall be limited to such contractual remedies as such Party may have for breach of this Agreement and such Party shall not have any non-contractual remedies in respect of such costs, losses, damages, liabilities, penalties or expenses including without limitation, any remedies based on principles of negligence.

16.6 Rights and Remedies Cumulative

17. SPECIAL PROVISIONS

17.1 Restriction on Disposition

(a) During the Term, if LANXESS sells, leases, mortgages or otherwise disposes of to any Person any interest in the Steam Distribution System being used to supply Steam hereunder, LANXESS shall require, as a condition thereof, that such Person agrees with BioAmber Sarnia to be bound by the provisions of this Agreement.

(b) During the Term, BioAmber Sarnia shall not sell, lease, mortgage, charge, transfer or dispose of to any Person any interest in the BioAmber Sarnia Facility or the Property unless such Person has entered into an agreement with LANXESS, in form and content satisfactory to LANXESS, acting reasonably, for assumption of this Agreement.

17.2 Early Termination of Agreement For Failure to Build

(a) Despite the Term of this Agreement as set out in Section 3.1 herein, BioAmber Sarnia may terminate this Agreement, by providing seven (7) Business Days advance notice to LANXESS, within thirty (30) days after the occurrence of any of the following events:

20.3 Exclusions from Relief

No Party shall be entitled to the benefits of the provisions of this Article 20 under any of the following circumstances:

(a) if the failure to perform or comply with any of the covenants or obligations herein imposed upon it was caused by arrest or restraint by governments or governmental agencies or the order of any court and such arrest, restraint or order was the result of a breach by the Party claiming suspension of the term

- 91 -

of a permit, license, certificate or other authorization granted by a governmental or regulatory body having jurisdiction or of any applicable laws, regulations or orders;

The Transferee further covenants that if it should, at any time, discontinue use of any of the pipelines and facilities, it shall forthwith, at its own cost and expenses, remove same and restore the Easement Lands to their previous condition and the easement and rights granted shall thereupon be terminated. In the event the Transferee fails to so remove the pipeline and facilities and restore the Easement Lands to their previous condition within a reasonable time, the Transferor may do so at the cost and expense of the Transferee.

The Transferee covenants that it, its agents and contractors shall maintain, at all times during installation or repair of the pipelines and facilities the following comprehensive liability insurance (or such greater amount as the Transferor may reasonably require from time to time) to protect the Transferor and Transferee against loss or damage:

The Transferee covenants that upon completing any construction or other work on the Easement Lands it shall forthwith restore the Easement Lands to the same condition as prior to such construction work and remove all waste material from the Easement Lands. In the event the Transferee fails to so restore the Easement Lands to their previous condition or to remove all waste material, within a reasonable time following completion of the construction or other work, the Transferor may do so without Notice at the cost and expense of the Transferee.

The Transferee covenants that it shall submit complete and adequate design drawings and specifications to the Transferor and obtain written approval for such drawings and specifications from the Transferor prior to commencing construction of any pipelines and facilities or any

The easement and rights hereby granted are subject to the right of the Transferor and its successors and assigns to use the Easement Lands at all times for any purpose whatsoever, provided such use does not unreasonably interfere with the rights granted to the Transferee hereunder. In the event that the location of any of the pipelines and facilities on the Easement Lands, in the reasonable opinion of the Transferor, at any time interferes with the Transferor’s use of the Easement Lands or any of its other lands, the Transferee shall, at the Transferor’s cost and in accordance with reasonable Notice from the Transferor, modify or change the pipelines and facilities or relocate the pipelines and facilities to a new location provided by the Transferor, provided that such new location is satisfactory to the Transferee, acting reasonably.

APPENDIX 1

Remediation Work

Background

AMEC Environment & Infrastructure, a division of AMEC Americas Limited (AMEC), was jointly retained by the Purchaser and the Vendor. to conduct a Soil and Groundwater Assessment (SGA) of the property located at 1265 Vidal Street, Sarnia, Ontario. This Soil and Groundwater Assessment was carried out in accordance with the Terms of Reference as provided in AMEC proposal/work agreement dated 29 June 2011.

The results of this study were documented in the AMEC report entitled “SOIL & GROUNDWATER ASSESSMENT PROPOSED BIO-AMBER SITE - INDUSTRIAL PROPERTY BIO-INDUSTRIAL PARK 1265 VIDAL STREET - FORMER LANXESS NBR UNIT SARNIA, ON”, on December 8, 2011.

[***]

Objectives / Expectations

The presence of the contamination did not appear in any of the other borehole samples tested in the AMEC report. Given the anticipated localized nature of the PHC contamination, it is proposed the soil from an area of 3m x 3m and to a depth of 3 m be excavated as an initial stage and placed immediately in a roll-off bin and covered for temporary storage while the soil is characterized. The sides and base of the excavation will be examined for visual evidence of contamination. If there is no evidence of contamination then confirmatory soil samples will be collected as discussed below. If visual evidence indicates that further excavation is warranted, then the excavation work will continue. The excavation depth will not extend into the grey clay layer (~3.5m). Excavation beyond 75 m³ will not proceed without discussion and agreement by both Parties. The excavation will remain open while the confirmatory sampling is being conducted.

The excavated soil will be analyzed to determine its appropriate waste classification: a toxicity characteristic leaching protocol (TCLP) analysis will be conducted on a single composite sample from each roll-off bin used in the excavation. Any soil from the excavation will be disposed of off-site.

Upon determining that there is no visual evidence of contamination at the edges of the excavation, five soil samples will be collected for confirmation: one from each wall and one from the base of the pit. The samples will be analyzed for PHC (F1-F4). The soil samples will be collected and placed in laboratory-supplied sample bottles and submitted for analysis at Lambton Scientific. The analytical results will be compared to the Table 3 Standard as defined by the MOE. Should the PHC concentrations be below the Table 3 Standard, then the excavation will be backfilled. However, should any of the confirmatory samples indicated that further PHC contamination exists above the Table 3 Standard, then additional excavation will be conducted. As stated above, additional excavation work will not proceed beyond 75 m³ without discussion and agreement by both Parties.

*Confidential Treatment Requested

- 120 -

Backfill

Following the confirmation of the sampling results, the excavated area will be backfilled and compacted with clean fill. Suitable backfill material available from the Vendor’s clean soil stockpile north east of its Butyl unit will be used for backfill. The surface at excavated area will not be restored to its original condition prior to excavation, although it will be left in a tidy state.
