PERSONAL AND CONFIDENTIAL

Mr. Matthew
Murphy

Dear Matt,

I refer to recent discussions in relation and
write to confirm the basis on which you (Murphy) will be seconded from Material Sciences Corporation (MSC) to Material Sciences (Shanghai) Trading Co., Ltd. The terms and conditions outlined in this letter of understanding
(Agreement) will be in effect only for the period of your employment on this assignment.



|1. | Employment and Duties.
|-- | ----------------------

You will be seconded from US Company, based in
Elk Grove Village, IL to Material Sciences (Shanghai) Trading Co., Ltd based in Shanghai, China, in the role of Vice President  China Sales & Marketing reporting to the MSC Chief Executive Officer. In such capacity, you will perform
such duties in relation to the business of Material Sciences Corporation and any affiliates of Material Sciences Corporation as may from time to time be assigned to you by senior management of Material Sciences Corporation or Material Sciences
(Shanghai) Trading Co., Ltd. You shall travel to other locations at such times as may be appropriate for the performance of your duties under this Agreement. In the event this international assignment is extended or a new assignment occurs, a new
agreement shall be executed. The new agreement will take into account the conditions that exist at the newly contemplated assignment location. You are subject to reassignment to any of the Material Sciences Corporation locations throughout the
world. Such reassignment will depend on the future needs of Material Sciences Corporation.

During your international assignment, you shall have any
authority to negotiate on behalf Material Sciences Corporation, to modify or accept contracts on behalf of Material Sciences Corporation, to otherwise bind Material Sciences Corporation to any contract with any third party and to conduct any
business in the name of or on behalf of Material Sciences Corporation.



|2. | Term.
|-- | -----

This assignment will begin June 7, 2008 and shall continue
for a period of up to three (3) years, unless sooner terminated by either party upon thirty days prior written notice. In the event MSC provides notice to Murphy, and Murphys spouse is still employed in China as an expatriate, MSC in its
notice to Murphy will provide six (6) months forewarning of the anticipated end of assignment date.



---

Regardless of any statement contained in this Agreement, Material Sciences Corporation shall have the
right to terminate your employment at any time for Cause as defined in section 8, upon thirty days prior written notice to you. The term of assignment may be extended by mutual agreement of the parties. Please note that all benefits
provided in this Agreement cease upon your return to the United States.

During any period that you are on assignment outside of China,
this Agreement and your employment by Material Sciences Corporation are subject to the proper and timely processing of passport, visa, work permit and other related documents, as well as medical and host country government clearances, required of
you in connection with such international assignment.



|3. | Compensation.
|-- | -------------

The elements of this
Agreement are based on MSCs policies and prior discussions with you, but may change at MSCs discretion.



| | 3.1 | Base Salary.
| | --- | ------------

Effective March 1, 2008 your
base salary will be $220,000.00 [U.S.] per annum. Once you are relocated to Shanghai, you will be paid by Material Sciences Corporation and by Material Sciences (Shanghai) Trading Co., Ltd. on a split payroll basis; 60% through the
Material Sciences (Shanghai) Trading Co., Ltd. FESCO and 40% Material Sciences Corporation U.S. payroll. Your base salary shall be payable in accordance with MSCs customary payroll practices but in no event less often than monthly. Your
performance evaluation and salary review will follow MSCs normal review cycle.



| | 3.2 | Applicable Bonuses.
| | --- | -------------------

Bonus: your
participation will be at the 40% level of base level under the MSC Management Incentive Plan (MIP). Bonuses will be paid on the split payroll basis.

Long Term Incentives (LTI): your participation will be at the discretion of the MSC Board of Directors.

Assignment Bonus: you will receive an annual assignment bonus of $20,000.00 (less applicable taxes and withholdings) paid after each 12 months on assignment. Partial years will be prorated. This bonus will be paid out of the U.S.
payroll.



| | 3.3 | Pre-transfer Trip Expenses.
| | --- | ---------------------------

Material Sciences
Corporation has paid expenses related to a pre-assignment visit to Shanghai for you and your spouse not to exceed five consecutive business days (or seven consecutive calendar days), as long as the expenses comply with Material Sciences Corporation
travel guidelines. The pre-assignment visit should be scheduled to coincide with business purposes. The purpose of this trip was to investigate and secure primary residence housing and determine which of your furnishings and household items will be
suitable for shipment to your new location.



2



---

| | 3.4 | Goods & Services Differential (G&SD).
| | --- | ---------------------------------------

A G&SD will be paid to you at a quarterly rate $8000.00 [U.S.] and will be paid in accordance with MSCs customary payroll practices, beginning with the payroll cycle once you have relocated to Shanghai, net
of applicable taxes and other required withholding. Your G&SD will be reviewed at the beginning of each quarter and will be adjusted (up or down) to reflect the then-current G&SD provided by the consulting firm of KPMG. This provision will
be paid out of the U.S. payroll.



| | 3.5 | Expenses.
| | --- | ---------

You shall be reimbursed for all
reasonable business expenses incurred in the performance of your duties pursuant to this Agreement to the extent such expenses are substantiated in writing and are consistent with the policies of MSC relating to the reimbursement of expenses.



| | 3.6 | Other Benefits.
| | --- | ---------------

You shall be entitled to
participate in all available Material Sciences Corporation employee benefit plans while on assignment in Shanghai. Plan provisions will dictate your inclusion or exclusion in such plans.

In addition, you will have coverage in the General Motors benefit plans for medical, dental and prescription drug provided in conjunction with your
spouses assignment with General Motors in Shanghai. In the event the General Motors coverage becomes unavailable to you and/or your spouse, MSC will make provisions to provide similar coverage to the extent that coverage is available and
such coverage has a similar cost to MSC plans provided employees in the United States.



| | 3.7 | Shanghai Housing.
| | --- | -----------------

You will be provided with
suitable housing consistent with the local market, including furniture rental as needed and basic utilities (electricity, gas and/or heating oil, water, trash disposal, and telephone installation charges but not ongoing telephone charges) to a
maximum cost of $6600.00 [U.S.] per month. Standard house upkeep such as house cleaning will be at your personal expense. Your Shanghai housing allowance will commence upon the beginning date of the lease in Shanghai. The lease will be entered into
between MSC and the leasing company/agent.



| | 3.8 | Taxes.
| | --- | ------

While on assignment, you will be
responsible for an amount that will be approximately the equivalent of the income tax and social security that you would have paid had you remained in your United States location. This amount is called home theoretical tax. Where
withholding is required, home theoretical tax will be calculated and deducted from your MSC compensation (including, but not limited to, base salary, annual incentive, stock option proceeds or other awards under MSCs equity programs). In all
instances you will ultimately be held responsible for a U.S. theoretical tax.



3



---

After your tax returns are prepared, your tax obligation will be recomputed to reflect the actual facts
for the year (Final Tax Obligation) and the difference between the taxes you have paid for the tax year and the Final Tax Obligation (your Tax Equalization Settlement) will be settled promptly thereafter. Because withholdings
may not have been at the level you are actually responsible for paying under the China location and U.S. tax laws or withholdings were not required to be made by Material Sciences Corporation at time of payment or exercise, you may be responsible
for paying additional taxes based upon your Tax Equalization Settlement. Conversely, if it is determined in your Tax Equalization Settlement that taxes in excess of your actual obligation under the China location and US tax laws were withheld, the
excess amount will be returned to you.

You will be required to comply with all laws regarding the filing of any required income tax
returns. You will be responsible and liable for the submission of host and home country tax returns. To assist you in this regard, Material Sciences Corporation will designate a tax preparer (Tax Preparer) and pay for the preparation of
required tax returns and Tax Equalization Settlement calculations for you for all tax years affected by the International Assignment. You are responsible for providing the Tax Preparer with complete and timely submission of tax data. You will be
responsible for penalties, interest or increased Tax Preparer fees that arise if you do not provide the Tax Preparer with this information in a timely manner.

If your spouse is required to file a non-MSC employment related tax return, MSC will not be responsible for those tax preparation expenses.

For purposes of the Material Sciences Corporation tax equalization policy, all calculations will be prepared and approved by the designated Tax Preparer.
Further, you will allow the Tax Preparer to provide sufficient information relating to your tax returns to Material Sciences Corporation for the sole purpose of completing the tax equalization process.



| | 3.9 | Travel Expenses.
| | --- | ----------------

Material Sciences Corporation
will reimburse air travel and incidental travel expenses for you and your accompanying spouse to travel to Shanghai upon the start of your assignment and from Shanghai to United States at the end of your assignment. Reimbursement will follow the MSC
travel policy in effect at the time of travel.



| | 3.10 | Disturbance Allowance.
| | ---- | ----------------------

To cover any incremental
miscellaneous expenses you may incur in connection with your international assignment MSC will pay you a one-time disturbance allowance of $20,000.00 [U.S.], net after taxes and other required withholdings. Such expenses might include, but are not
limited to: banking fees, China drivers license, luggage, the conversion or purchase of electrical appliances, the connection or disconnection of utility services and purchase of draperies. This payment will be delivered to Murphy, at his
discretion, in either two (2) lump sum payments or incorporated in his monthly payroll payments. This provision will be paid out of the U.S. payroll.



4



---

| | 3.11 | Moving and Storage.
| | ---- | -------------------

MSC will reimburse moving expenses, surface
shipment of up to one 40-foot container load and an air shipment of up to 2000 pounds net weight, associated with your relocation from the United States. These expenses include packing, crating, unpacking, wardrobe service, insurance, surface
shipping, storage in transit, delivery and all expenses involving customs clearance of normal household goods and personal effects.



| | 3.12 | Shanghai Transportation.
| | ---- | ------------------------

MSC will enter into a contract with an auto
leasing company and pay the fees directly associated with the lease, including the assignment of a driver to you. Under this paragraph, the total expense MSC will assume will not exceed $45,000.00 [U.S.] per year.

MSC will not pay or reimburse for shipping any auto (or other vehicle) to or from an international assignment.



| | 3.13 | Visas and Passports.
| | ---- | --------------------

All costs involving the securing of required
visas, passports, work permits and other related documents for you and your accompanying spouse will be paid or reimbursed by the MSC, excluding any payments made by General Motors on behalf of your spouse for the items listed within this provision.



| | 3.14 | Home Leave.
| | ---- | -----------

Following the establishment of your residence in Shanghai,
your spouse is eligible for two (2) complete round trips per 12-month period to the United States. Under this provision, MSC will not allow the carryover of any unused home leave trips. You are expected to coordinate your travel with business
trips when joining your spouse for her home leave travel. Reimbursement will follow the MSC travel policy in effect at the time of travel.



| | 3.17 | Emergency Travel.
| | ---- | -----------------

In the event of a serious illness or death of a
member of your or your spouses immediate family (mother, father, brother, sister, or child), MSC will reimburse round-trip airfare for you and your spouse to an appropriate location. Reimbursement will follow the MSC travel policy in effect at
the time of travel. Serious illness is defined as one of an immediate life threatening nature, wherein the immediate family members condition likely will result in death, without chance of recovery.

---

|4. | Work Schedule.
|-- | --------------

You agree that you will observe the work schedule and
holidays in effect in Shanghai. You will not normally be entitled to overtime pay should the responsibilities of your position require that you work beyond this schedule. While on assignment, you will continue to receive vacation benefits in
accordance with the MSC policy.



|5. | Business Conduct.
|-- | -----------------

You are expected to comply with the United States
Foreign Corrupt Practices Act, and with local law applicable to government payments. Except as permitted under the express written policies of Material Sciences Corporation, you shall not, directly or indirectly, pay, give or offer anything of value
to any foreign government officer, employee or representative, or to any foreign political party or candidate for or incumbent in any foreign political office, for any personal or business reasons, including in order to assist in obtaining,
retaining or directing business. In addition, you agree to obey all countries laws and regulations and respect lawful customs. Further, it is understood that in accepting this assignment, you agree that you will not engage in any employment or
business enterprises that would in any way conflict with your service with, and interest of, Material Sciences Corporation or Material Sciences (Shanghai) Trading Co., Ltd.

You agree to avail yourself of training related to the United States Foreign Corrupt Practices Act with the law firm MSC engages as general council as soon as
practical following signature of this Agreement.

|7. | Repatriation.
|-- | -------------

Once your international
assignment has been successfully completed, you are entitled to repatriation benefits for yourself and accompanying dependents under the same guidelines set forth under paragraph 3.11 and storage of those goods in the U.S. for up to 60 days. In
addition, you will receive a disturbance allowance equal to one months base salary, net of taxes and other required withholding.



|8. | Severance Pay.
|-- | --------------

Provisions for severance pay
are provided under a Change in Control (CIC) agreement entered into between yourself and MSC and dated April 24, 2008.

In addition to the provisions found under the CIC agreement, if MSC terminates your employment not for Cause, while on international assignment, and you return to the United States within 30 days, MSC will assume the cost of
one-way direct air travel expenses for you and your accompanying family members under the same guidelines set forth under paragraph 3.9, transportation of household goods to an appropriate U.S. location under the same guidelines set forth in
paragraph 3.11 and storage of those goods for up to 60 days. In addition, you will receive a disturbance allowance of one months base salary, net of taxes and other required withholding. In no instance, however, will this disturbance allowance
exceed the equivalent of $20,000.00 [U.S.] net of taxes and other required withholding.

There is no assistance on relocation, including a
disturbance allowance, in the event you i) voluntarily terminate your employment due to acceptance of a position with another employer or ii) are terminated for Cause in which event all benefits under this Agreement immediately cease.

The definition of Cause under this provision is that definition as found within your CIC.



|9. | Termination/Severance Payments.
|-- | -------------------------------

Should
termination or severance payments become payable upon your transfer to another location or upon termination of your employment with MSC, you agree to forfeit your rights in writing to all such payments under this Agreement or, if you receive such
payments, you will immediately return them to MSC. In the event the waiver of such payments is unenforceable under local law, you agree to fully offset the value of such payments due to you from other plans or benefits under which you may be
eligible.

You hereby consent to the offset by MSC of amounts you may owe MSC hereunder (i.e., home theoretical tax and/or Tax Equalization
Settlement) against sums owed to you by MSC (i.e., salary, bonus, termination payments and other benefits).



|10. | Severability.
|--- | -------------

The provisions of this
Agreement are severable. If any provision is found by any court of competent jurisdiction to be unreasonable and invalid, that determination shall not affect the enforceability of the other provisions.

construed in accordance with and governed by the laws of the State of Illinois, without regard to the choice of law principles thereof. Any suit, action or other legal proceeding arising out of or relating to this Agreement shall be brought
exclusively in the federal or state courts located in the State of Illinois. You agree to submit to personal jurisdiction in the foregoing courts and to venue in those courts. You further agree to waive all legal challenges and defenses to the
propriety of a forum in China, and to the application of China law therein.



|12. | Third Party Beneficiary.

Each affiliate of
the MSC is a third party beneficiary of this Agreement and each of them has the full right and power to enforce rights, interests and obligations under this Agreement without limitation or other restriction.



|13. | No Waiver.

No failure or delay by any party
in exercising any right, power or remedy under this Agreement shall operate as a waiver thereof, nor shall any single or particular exercise of the same preclude any further exercise thereof or the exercise of any other right, power or remedy.

Without limiting the foregoing, no waiver by any party of any breach of any provision of this Agreement shall be deemed to be a waiver of
any subsequent breach of that or any other provision of this Agreement.
