 NOW, THEREFORE, in consideration of the understandings and agreements hereinafter set forth, the
parties hereto mutually agree as follows: 
 ARTICLE 1 

Formation of Joint Venture 
 1.1. Establishment of Joint Venture. AVI and WVI hereby establish an unincorporated Joint Venture to carry on, as owners, a business for profit for the purposes set forth below. The Joint
Venture shall be established and conducted as a general partnership pursuant to the Uniform Partnership Act as adopted in the state of Delaware (hereinafter referred to as the “General Partnership Law”) with AVI and WVI as sole and
equal partners; provided, however, in the case of any conflict between the provisions of the Agreement and the General Partnership Law, the provisions of this Agreement shall control. 

1.2. Name. The Joint Venture shall operate under the name of “Armstrong/Worthington Venture”, or such other name
as to which the Members may mutually agree. 
 1.3. Office. The principal office of the Joint Venture shall be
located at such location as the Board of Directors may designate. 
 1.4. Purpose of the Joint Venture. The
purpose of the Joint Venture shall be to construct, equip and operate one or more facilities for the production and sale of Grid worldwide. 
 1.5. Ownership. Except as otherwise agreed to in writing by the Members, AWI and WVI shall each have a 50% interest in the Joint Venture. 







 1.6. Term. The Joint Venture shall continue in existence for an initial term
expiring as of December 31, 2001 (the “Initial Term”), unless either: earlier terminated pursuant to Article 11 hereof; or extended by mutual written agreement of the Members. If neither Member elects to terminate the
Joint Venture at the end of the Initial Term, the term of the Joint Venture shall be extended from three year period to three year period (i.e. the first extension will end December 31, 2004 and if not then terminated, the second extension will
end December 31, 2007, etc.) unless terminated pursuant to Article 11 hereof, or otherwise extended by mutual written agreement of the Members. Except as provided in Article 10 or Article 11 hereof, neither Member shall withdraw
from the Joint Venture for any reason during the Initial Term of the Joint Venture and any extension thereof, without obtaining the prior written consent of the other Member. 
 1.7. Transferability of Interest. Except as provided in Article 10 hereof, neither Member shall transfer, sell, assign, pledge, hypothecate, give, or otherwise dispose of all or any
portion of its interest in the Joint Venture without the prior written approval of the other Member, 
 1.8.
Organizational Costs. Except as otherwise agreed by the Members, all costs incurred by a Member in connection with the establishment of the Joint Venture shall be borne by the Member incurring such costs. 

1.9. Effective Date. The contributions of the Members’ Current Grid Businesses shall be made to be effective as of
June 1, 1992 (the “Effective Date”), which shall be the date the Joint Venture commences its Grid Business. 
 ARTICLE 2 
 Combining Existing Businesses 

2.1. Items to be Contributed. The Members shall contribute their Current Grid Businesses to the Venture as described below
as of the Effective Date. 

  
 2 








 2.1.1. Machinery and Equipment. WVI and AVI shall contribute to the Venture
all the Machinery and Equipment, used in their Current Grid Businesses as shown on Exhibits 2.1.1A and 2.1.1B respectively. The Grid Machinery and Equipment to be contributed by AVI shall include the Machinery and Equipment Armstrong has on
order and the Machinery and Equipment not on order but for which funding has been approved by Armstrong, both as shown on Exhibit 2.1.1C, and Armstrong (and not the Joint Venture) shall be responsible for making full payment for such Machinery
and Equipment. Furniture related solely to the Current Grid Businesses of each Member will also be contributed. 
 2.1.2.
Inventory. AVI and WVI shall contribute to the Venture all of the useable inventory related to the Current Grid Businesses, including supplies, raw materials, work-in-process and finished goods. The Members shall agree upon a method of
determining what inventory will be useable by the Venture. The parties agree that the fair market value of any item of finished goods inventory being contributed by either Member shall be equal to 80% of the average current selling price to existing
customers for such item and any raw material will be valued at cost. The Members shall also agree upon a fair valuation for each other item of inventory being contributed to the Venture. The Members shall determine the aggregate value of the
inventory being contributed by AVI and of the inventory being contributed by WVI as of the Effective Date, and shall take physical inventory if needed. The Members shall prepare a Schedule showing the amount of useable inventory, by category and
product, contributed by each Member to the Joint Venture as of the Effective Date. 
 In order to equalize the value of the
inventory being contributed, the Member contributing inventory with a lesser aggregate value (the “Lesser Inventory Member”) shall make a capital contribution, in cash, to the Joint Venture in the amount by which the aggregate
agreed upon value of the inventory being contributed by the Lesser Inventory Member is less than the aggregate agreed upon value of the inventory being contributed by the other Member (the “Inventory Difference”). As used herein,
such cash payment shall be referred to as the “Inventory Equalization Contribution,” and shall be paid to the Joint Venture within 15 days after the amount is determined. 

As an alternative to the foregoing paragraph, if the Members mutually agreed, the Lesser Inventory Member will pay to the other Member
50% of the amount of the Inventory Difference, which payment shall be made within 15 days after the amount is determined. If this alternative is agreed to, the amount of the inventory so purchased from the other Member shall be considered as a
contribution to the Venture by the Lesser Inventory Member so that the total amount of inventory contributed by each Member shall be equal. 

  
 3 








 2.1.3. Trademarks, Patents and Proprietary Information. AVI and WVI shall
contribute to the Venture all of the Trademarks and Patents and all inventions, formula, trade secrets, manufacturing processes, know-how and other similar intellectual property rights and proprietary information relating to their Current Grid
Businesses; provided, however, that both National and Armstrong shall be entitled to retain their corporate names. The above provisos notwithstanding, however, the Joint Venture shall be entitled to use the Armstrong name and trademark and any
derivations thereof (royalty free) in connection with the manufacture and sale of its Grid. AWI and the Venture shall enter into a License Agreement, substantially in the form of Exhibit 2.1.3 (the “License Agreement”), with
respect to the use of the “Armstrong” name and trademark. 
 2.1.4. Purchase Orders, Records, Etc. AVI
and WVI shall contribute to the Venture, all books, records, purchase orders, sales orders, memos, correspondence, customer files and lists, computer software, designs, drawings, engineering data and similar intangible assets and proprietary
information relating to their Current Grid Businesses; provided, however, that excluded from such items shall be any items which also relate to a business of the Member Group other than the Current Grid Business, but the Member shall contribute the
portion of those items which are easily divisible from the information or items beneficial to the other business of the Member Group. The above notwithstanding, the Venture may elect not to assume any contractual obligations which it does not wish
to assume. 
 2.2. Items to be Retained by Members or their Affiliates. 

2.2.1. Cash. National and Armstrong shall retain all cash relating to their Current Grid Businesses. 

2.2.2. Accounts Receivable. National and Armstrong shall retain all of the accounts receivable relating to their Current
Grid Businesses existing as of the Effective Date, and shall be responsible for collecting such accounts. The above notwithstanding, the Venture will provide reasonable assistance to Armstrong and National, at no charge, in collecting such accounts
receivable. 

  
 4 








 2.2.3. Land and Buildings. Each Member Group will retain all of its existing
land and buildings and Fixtures relating thereto (excluding trade fixtures used in the manufacturing process of the Current Grid Business) even if used for their Current Grid Businesses. Furniture will be retained by the Member Groups unless it is
used solely in the Member’s Current Grid Business. If the Venture elects to continue manufacturing at current locations, the Venture shall lease any land and buildings currently used by Armstrong or National in their Current Grid Businesses at
a fair market value per square foot. Separate leases for each location shall be executed. If the NRM Malvern facility is used by the Venture, common items such as utilities, etc. will be allocated between NRM’s steel processing operation and
the Venture on a fair basis to be agreed upon by the parties. 
 2.2.4. Liabilities. The Venture will not assume
any liabilities of either the National or the Armstrong Current Grid Business except those relating to compliance with purchase orders, sales orders, etc. being contributed to and accepted by the Venture as set forth above. Each contract assumed by
the Venture shall be listed on, a schedule to be attached hereto. 
 2.3. Warranty Work. National and Armstrong
shall be responsible for any warranty claims which may be made with respect to products sold by their respective Current Grid Business prior to the effective date of the Venture. However, the Venture agrees that it shall respond to and handle such
warranty claims, provided that the party responsible for such claims shall pay the Venture its out of pocket costs, but not employee salaries or similar items, incurred in responding to such warranties. 

2.4. Environmental Liabilities. With respect to facilities previously operated by a Member or its Affiliate, the Joint
Venture shall be liable for any conditions, whether on or off site, resulting from the emission or discharge of regulated substances into the air or water or the use, storage, generation, disposal or release or threatened release of any hazardous
substance, contaminant, chemical, or material defined as hazardous pursuant to the federal Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. ¶ 9601 et sec., as amended, or the federal Resource
Conservation and Recovery Act, 42 U.S.C. ¶ 9202 et sec., as amended, 

  
 5 








 
including petroleum and petroleum products, caused by operations of the Joint Venture on or after the Effective Date and shall indemnify, defend and hold harmless the Member Group from all costs
related to investigation and remediation of any environmental conditions resulting therefrom. However, each Member Group shall retain liability, if any, for any environmental impairment which may exist with respect to any Member Group’s
respective land and buildings prior to the Effective Date and any environmental conditions resulting from a Member Group’s operations whether on or off site, other than those caused by operations of the Joint Venture, on or after the Effective
Date, and shall indemnify, defend and hold harmless the Joint Venture from all costs related to investigation and remediation of same. 
 ARTICLE 3 
 Financing The Venture 

3.1. Capital Contributions of the Members. 
 3.1.1. Initial Capital Contributions. Upon the formation of the Joint Venture, each Member shall make an initial cash capital contribution to the Joint Venture as follows: 

 

					
	Partner	  	Initial Capital Contribution	 
	 AVI
	  	$	10,000	  
	 WVI
	  	$	10,000	  
	 Total
	  	$	20,000	  

 3.1.2. Capital Contribution of Grid Business. In addition to the cash capital contributions
set forth in Section 3.1.1, each Member shall contribute to the capital of the Joint Venture those assets of its Current Grid Business as set forth in Section 2.1. The parties shall reasonably agree upon the fair market value of the
tangible assets of each Member’s Current Grid Business being contributed by such Member and such fair market value shall be credited to the respective Member’s Capital Account. The Inventory Equalization Contribution shall also be credited
to the Capital Account of the Member making such payment. 

  
 6 








 3.1.3. Additional Capital Contributions. If the Members should at any time
determine that the Joint Venture needs additional funds in order to continue to transact business, as provided in Section 3.3, the Members agree, to the extent practicable and economically feasible, that the funds shall be obtained through
loans obtained by the Joint Venture. If the Joint Venture is unable to, or the Members mutually elect not to, borrow such additional funds, then each Member agrees to make additional cash capital contributions to the Joint Venture, in proportion to
its Interest in the Venture, in order to provide the Venture with the necessary funds. If either Member should fail to make such additional capital contribution, then the other Member may, at its option, make on behalf of the non-contributing
Member, another additional cash contribution in the non-contributing Member’s place and in an amount equal to that which the non-contributing Member was obligated but failed to make. In such event, the additional cash capital contribution shall
be treated as a loan from the contributing Member to the non-contributing Member, and shall bear interest at the announced Prime Rate of Citibank plus 3% per annum (but not in excess of the maximum rate permitted by law) and shall be payable
not later than 30 days following the date the additional cash contribution is made. Capital calls shall be made only upon mutual consent of the Members. 
 3.1.4. Capital Contributions to Pay Liabilities. The Members shall not be obligated by this Agreement to make any additional or other capital contributions to the Venture, other than as
provided in Sections 3.1.1, 3.1.2 and 3.1.3 or except to the extent that either Member may be obligated to do so by a creditor of the Venture under applicable state partnership laws. Any sum paid by either Member to or on behalf of the Venture
to the extent such Member was obligated to do so by a creditor of the Venture under applicable state partnership law shall be regarded and treated as a capital contribution to the Venture by the Member who made it and shall be credited to its
Capital Account. No provision of this Section 3.1.4 shall be deemed to limit a Member’s right of contribution from the other Member to the extent that the Member is obligated to make an additional capital contribution to the Venture by a
creditor of the Venture under applicable state partnership law. 
 3.1.5. Capital Account. A separate account
entitled “Capital Account” shall be established and maintained for each Member on the books of account of the Joint Venture. Such Capital Account shall reflect all contributions and withdrawals of capital of such Member. No withdrawals
shall be made from the Capital Account of a Member, except as may be authorized by the Board of Directors. 

  
 7 








 3.1.6. No Guaranteed Return on Capital. A Member shall not be entitled to be
paid any interest or specified rate of return on its capital contributions or its Capital Account. The Venture shall not be obligated to repurchase or to redeem the interest of either Member, and the Member shall not have the right to withdraw or to
demand a return of its capital contributions, whether in cash or in assets other than cash, except as specifically provided in the applicable provisions of this Agreement. 
 3.2. Members, Interest in the Venture. The Interest of each Member in the Venture for all purposes of this Agreement shall be its share of the Venture’s assets, liabilities and
equities, its allocations of profit and loss and its distributions of cash or other assets which share shall be equal to the percentages specified as follows: 
  

					
	Member	  	Initial Interest
in the Venture	 
	 AVI
	  	 	50	% 
	 WVI
	  	 	50	% 

 3.3. Financing. The Members agree that, to the extent practicable and economically
feasible, all funds required for the Joint Venture in excess of the initial capital contributions of the Members, shall be obtained by loans arranged for and obtained in the name of the Joint Venture. Both Members agree to use their best efforts to
assist in obtaining such necessary financing. To the extent required by the financing institutions, the Members agree to guarantee, or cause their respective parents to guarantee, their proportionate share of any such financing on a
“several” basis (i.e., so that neither Member (or their Affiliates) will be liable for the portion guaranteed by the other Member). Any necessary guarantees shall be furnished on terms reasonably satisfactory to the respective lenders and
Members. In lieu of guarantees of loans from financial institutions, the Members shall have the option of making (or having their Affiliates make) direct loans to the Joint Venture. If one Member elects to make such a loan and the other secures
financing for the Joint Venture from a financial institution, the interest rate payable to the lending Member shall equal the rate payable to the financial institution. If one Member’s guarantee cannot support an interest rate as low as the
other, arrangements will be made so that the Member obtaining the higher rate will make up the difference in the two rates.

 ARTICLE 4 
 Facilities 
 4.1. Selection of Sites. The Board of
Directors will determine the location of the initial manufacturing facilities for the Joint Venture and any future Joint Venture facilities. Unless the Board otherwise determines, National’s plant in Malvern, Pennsylvania shall be one of the
initial sites. The Members anticipate establishing shortly after the creation of the Joint Venture, a west coast manufacturing facility and a manufacturing facility to serve the European market. The timing for the start-up of such facilities shall
be determined by the Board of Directors. 
 4.2. Existing Facilities. 

4.2.1. Lease of Facilities. If any existing manufacturing facility of a Member Corporation is to be operated by the Joint
Venture, the Joint Venture will lease (or sublease) such facility from the Member Corporation currently operating the facility at a fair market value to be negotiated between the parties. Any common items will be reasonably allocated. The lease or
sublease of such facilities shall be documented through a lease or sublease reasonably negotiated between the parties. 

4.2.2. Employees at Existing Facilities. Employment of the employees who work for either the Armstrong or the National
Current Grid Business at existing facilities will be handled in accordance with Section 5.2. 
 4.2.3. Termination
Costs. Armstrong shall be responsible for any costs relating to or arising from the closing of the Sparrow’s Point or Franklin Park facility, if such closing occurs within five years after the Effective Date (even if they are operated
by the Joint Venture for some period of time), including without limitation, any termination costs related to employees at such facility; provided that if any such employees are transferred to other Joint Venture locations, the Joint Venture and not
Armstrong shall be responsible for any expenses the employer may incur in relocating such employees. 

  
 9 








 4.3. New Facilities. The Board of Directors will determine the sites for any
of the new Joint Venture facilities. The Board of Directors shall also determine the design, construction and equipping of such facilities, including any lease or contractual terms related thereto. The Board of Directors shall determine a budget for
completing the construction, improvement and equipping of any new facilities including the purchase and installation of any new Machinery and Equipment (or the movement of any Machinery or Equipment contributed by either Member). 

4.4. Contracts. All equipment and materials needed for the construction and equipping of the facilities for the Joint
Venture may be contracted for in the name of the Joint Venture, Armstrong or National; provided, however, that any such equipment and material contracts entered into in the name of a Member Corporation shall be assigned to the Joint Venture or title
to the equipment and materials transferred to the Joint Venture not later than delivery to the facility or promptly thereafter, and the Joint Venture shall, except as provided in Section 2.1.1 hereof, reimburse the Member Corporation for the
actual amount paid by the Member Corporation for such materials and equipment under the terms of the contract governing such acquisition. 
 4.5. Existing Warehouses. The Venture will assume the leases and other costs for any existing NRM Grid warehouses and distribution facilities. The Board of Directors shall determine how and
when to integrate or otherwise change the distribution operation for its business. The Joint Venture shall be responsible for the cost of closing any warehouse or distribution facility including, without limitation, costs relating to terminated
employees. 
 4.6. Trucking. The Joint Venture shall enter into an agreement or arrangement with NRM Trucking
Company pursuant to which NRM Trucking Company shall provide trucking services to the Joint Venture, in substantially the manner currently provided to National’s Current Grid Business, provided costs are reasonable in light of the service being
provided and rates otherwise available, and provided any necessary regulatory authority is in place. 
 ARTICLE 5

 Operation of the Joint Venture 
 5.1. Operating Management. The Board of Directors of the Joint Venture shall appoint a Chief Executive Officer. Until December 31, 1996, the Chief Executive Officer shall be nominated
by WVI, subject to approval of the Board of Directors. Thereafter, the Board of Directors shall nominate and select the Chief Executive Officer. The Chief Executive Officer shall be responsible for the day to day operation of the Joint Venture. The
Board of Directors shall also appoint such other officers as it deems appropriate. 

  
 10 









 The Management of the Joint Venture will be broken down into the following areas of
responsibility unless otherwise determined by the Board of Directors: 
 (a) Manufacturing; 

(b) Marketing, including product development, pricing, position and placement; 

(c) Logistics; and 
 (d) Financial. 
 The Board of Directors may appoint separate individuals to be
responsible for one or more of those areas, or the Chief Executive Officer can be directly responsible for any such areas. Any officers appointed for the Joint Venture shall report to the Chief Executive Officer, unless otherwise directed by the
Board of Directors. 
 5.2. Employees 
 5.2.1. National Employees. If the Joint Venture elects to operate National’s grid facility in Malvern, Pennsylvania, the employees of National’s Current Grid Business at that
facility will become employees of the Joint Venture, at a time selected by the Board of Directors. If the parties agree, there may be a phase-in period during which the employees of National’s Current Grid Business will remain National
employees, but would be leased to the Joint Venture by National as provided in the National Support Agreement. 
 5.2.2.
Armstrong Employees. The employees of the current Armstrong grid facilities will remain Armstrong employees for some period of time. If the Armstrong facilities are operated during such period of time, the Joint Venture will lease those
employees from Armstrong as provided in the Armstrong Support Agreement. If the Joint Venture elects to operate the Armstrong facilities indefinitely as Joint Venture facilities, the employees of Armstrong who are furnished on a lease basis to the
Joint Venture will eventually become employees of the Joint Venture, at a time selected by the Board of Directors. Notwithstanding 

  
 11 









 
anything to the contrary herein, Armstrong shall remain responsible for any termination costs related to any Franklin Park and/or Sparrow’s Point employees whose employment terminates within
five years after the Effective Date (even if such facilities are operated by the Joint Venture for some period of time); provided that if any such employees are transferred to other Joint Venture facilities, the Joint Venture and not Armstrong shall
be responsible for any expenses the employer may incur in relocating such employees. 
 5.2.3. Key employees. The
Members agree that any Key Employees of National or Armstrong (or their Affiliates) which are transferred to and work for the Joint Venture shall be available to the Member Group (or their Affiliates) for whom they previously worked to be
transferred back to the other operations of that Member Group (or their Affiliates); provided, however, that the timing of any such transfer will not be disruptive to the Joint Venture’s operations, appropriate replacements are available and
the Venture has no other compelling reasons to object to such transfer. 
 5.3. Sales. The current intent of the
Members is that the Grid produced by the Joint Venture will be sold for the Joint Venture by the Armstrong sales force which also sells Armstrong ceiling board. Such selling efforts shall be performed in accordance with a Sales Representation
Agreement to be entered into between the Joint Venture and Armstrong, substantially in the form of Exhibit 5.3 hereto, pursuant to which Armstrong will have its sales force use all reasonable efforts to sell Grid. The above notwithstanding, the
Joint Venture may employ such additional sales representatives or sales agents as the Board of Directors determines. Further, should the Board of Directors determine that its Grid can be sold in a more effective manner, it shall be entitled to amend
or terminate its sales agreement with Armstrong in a manner which is fair and reasonable to both parties. 
 5.4. Steel
Purchases. The Joint Venture agrees to provide NRM or its affiliated Worthington Steel Companies (collectively, “Worthington Steel”) the first right to supply the steel used at each Joint Venture facility for the production
of its Grid, and the Joint Venture shall purchase from Worthington Steel such steel as to which Worthington elects. However, Worthington Steel may exercise its election under this provision only with respect to those items of steel as to which:
(a) Worthington Steel is competitive in price, quality and other terms for 

  
 12 









 
prime steel with respect to such item or items; and (b) Worthington Steel (i) has a facility within a reasonable distance from the Grid facility, or (ii) can still provide similar
service, delivery and pricing as steel suppliers which are close to the Grid facility. If Worthington Steel does not elect to supply any item of steel, or any portion thereof, or if Worthington Steel does not meet the provisions of the prior
sentence as to any item of steel, then the Joint Venture shall be free to purchase from other parties, any such item, or the portion of such item, not being supplied by Worthington Steel. In setting the prices for any steel to be supplied by
Worthington Steel, the parties shall consider the price that could be obtained from others to supply steel of the same quality and the same level of service, the absence of commissions, and the limited credit risk in selling to the Venture. Pricing
for said steel will be set in good faith based upon fair market value for the type of steel product and services required. Purchasing arrangements will be reviewed by the Board of Directors every six months, or sooner if needed. 

5.5. Costs. All costs of the Joint Venture, including amounts paid to the Members or their Affiliates pursuant to the
contracts described herein, shall be paid by the Joint Venture. 
 5.6. Allocation and Distribution of Profits.
Except as otherwise agreed by the Members, all profits and losses of the Joint Venture shall be allocated to each Member according to their respective Interests in the Venture. 

5.7. Cash Distributions. Cash shall be distributed to the Members from the Venture in such amounts and at such times as the
Board of Directors may determine. Each distribution of cash shall be made to the Members in proportion to their Interests in the Venture at the time of such distribution. 
 5.8. Investment of Funds. All cash of the Joint Venture shall, to the extent possible, be maintained in such interest bearing bank accounts (“sweep” account) in the name of, or for
the benefit of, the Joint Venture or in such short term investments as the Joint Venture’s Board of Directors may determine from time to time. No Member shall be entitled to take an advance against anticipated future distributions or borrow
funds from the Joint Venture without the approval of the Board of Directors. If at any time a Member so requests, all cash funds of the Joint Venture shall be kept solely in segregated accounts of the Joint Venture. 

  
 13 









 5.9. National Support Agreement. The Joint Venture shall enter into with
National, the National Support Agreement, substantially in the form of Exhibit 5.9 hereto, pursuant to which National shall provide the Joint Venture certain administrative, support and operational services for a fee which shall be agreed upon
between National and the Joint Venture. 
 5.10. Armstrong Support Agreement. The Joint Venture shall enter into
with Armstrong, the Armstrong Support Agreement, substantially in the form of Exhibit 5.10 hereto, pursuant to which Armstrong shall provide the Joint Venture certain administrative, advertising, product development, technical, support and
operational services for a fee which shall be agreed upon between Armstrong and the Joint Venture. 
 5.11. Other
Contracts. The Joint Venture may enter into other contracts and agreements with either Member or its Affiliates which will include a reasonable profit or fee, but only with the prior consent of the Board of Directors. Any such agreement,
including the Sales Representation Agreement, the National Support Agreement and the Armstrong Support Agreement, shall not be modified or amended or the terms thereof extended without the prior consent of the Board of Directors. 

5.12. Assistance to the Joint Venture. Each Member agrees to use reasonable efforts to assist the Joint Venture in the
conduct of its business and to communicate to the Board of Directors of the Joint Venture promptly all information, requests, and other matters relating to the affairs of the Joint Venture received by such Members. 

5.13. Taxes. The Board of Directors shall appoint an appropriate person or entity to prepare and file any tax returns or
other filings which may be appropriate for the Joint Venture. 
 5.14. Compliance with Lavs and Standards of
Conduct. Each Member, for itself, its Affiliates and their directors, officers, agents, employees and other persons authorized to act in its or their behalf agrees that the business of the Joint Venture shall be conducted in conformity with
all applicable laws, statutes, regulations, rules, policies, and orders as in effect from time to time.

persons appointed by WVI. Each director shall serve at the pleasure of the Member appointing such director. All appointments and withdrawals of appointment shall be made by written notice to the other Member. Each Member may, but need not, designate

6.3. Meetings. 
 6.3.1. Time and Place. The Board of Directors shall meet at least quarterly (unless the Members or the Board of Directors otherwise determine) on such dates as the Board of Directors may
agree in writing. Additional meetings shall be held at the written request of any director on five business days notice issued to all directors by the director requesting the meeting. Unless otherwise agreed by the Board, the meetings shall
alternate between a location reasonably designated by the AVI directors and a location reasonably designated by the WVI directors.

 6.3.2. Quorum. A quorum for all meetings of the Board of Directors shall be
four directors represented in person or by proxy. 
 6.3.3. Telephone, Meetings and Consent Actions. Any director

Directors shall be kept by such person as is designated by the Board, and copies of all Board of Directors minutes and other resolutions approved by the Board of Directors shall be given to each director. 

6.5. Officers. 
 6.5.1. Chairman. The Members agree that one of the members of the Board of Directors shall be appointed Chairman of the Board of Directors to preside at the meetings of the Board of
Directors. In the event that the Chief Executive Officer of the Joint Venture was an employee of either Member or one of its Affiliates at the time he was so appointed, then the Chairman shall be selected from the members of the Board of Directors
appointed by the other Member. If the Chief Executive Officer of the Joint Venture was not an employee of either Member or their Affiliates when so appointed, then the Chairmanship shall alternate each year between a member of the Board of Directors
designated by WVI and a member of the Board of Directors designated by AVI. The Chairman of the Board shall not be considered an officer of the Joint Venture. 
 6.5.2. Operating Officers. Until December 31, 1996, WVI shall nominate, subject to the approval of the Board of Directors, the Chief Executive Officer of the Joint Venture. Thereafter
the Chief Executive Officer shall be nominated and appointed by the Board of Directors. The Chief Executive Officer shall be responsible for the day-to-day operation of the Joint Venture’s business. The Board of Directors shall also appoint
such other officers or assistant officers as the Board of Directors deem appropriate in order to provide for the operating management of the Joint Venture.

have, without limitation, the specific power to:

Section 11.5 below, by either Member to continue conducting the business of the Joint Venture, then the Members shall attempt to sell the business of the Joint Venture to a third party. If an acceptable buyer cannot be found within a reasonable

 (a) To payment of the expenses of the sale or liquidation; 
 (b) To payment (or
creation of reserves for payment) of the debts and liabilities of the Joint Venture, first to non-members and then to Members for services, advances or otherwise; 
 (c) To payment to each Member of its share of profits which have been accumulated and not previously paid out; 
 (d) To payment to each Member of the amounts outstanding to its credit with respect to its Capital Account; and 
 (e) T0 divide the surplus, if any, in proportion to the interest of each Member in the Joint Venture.

immediately shall pay to the Joint Venture all amounts owing to the Joint Venture, together with its proportionate share of all contributions required by law to be paid by the Members for the payment of liabilities of the Joint Venture. 

  
 26 









 11.4.2. Accounting on Liquidation. If the Joint Venture is liquidated, each
Member shall be furnished with a statement (which shall, at the option of either Member, be certified by the independent auditor who, if not already appointed, shall be appointed by mutual agreement of the Members of the Joint Venture), which shall
set forth the assets and liabilities of the Joint Venture and the status of the Capital Accounts of the Members as of the date of the completed liquidation, taking into account distributions and payments as provided in Section 11.4.1
hereinabove, the allocation of all gain or loss realized by the Joint Venture on the liquidation of property and assets of the Joint Venture, and the allocation of any tax benefits. Notwithstanding the foregoing provisions, upon the dissolution,
liquidation and termination of the Joint Venture, if either Member has a negative Capital Account, then it shall make a capital contribution to the Joint Venture, either to pay creditors of the Joint Venture or to distribute to the other Member, of
an amount of money equal to the amount of the negative balance in such Member’s Capital Account in order to restore such Capital Account balance to zero. Such capital contribution shall be made within 90 days after the liquidation of the Joint
Venture. 
 11.4.3. Payment of Costs. The Joint Venture will pay all costs incurred in the sale or other
disposition of its assets upon liquidation and any other expenses incurred in the liquidation and dissolution. 
 11.4.4.
Purchase by a Member Group. If either Member or an Affiliate thereof buys the business of the Joint Venture as part of a sale or other disposition of assets upon liquidation, the price to be paid for the business shall in all events be
calculated as if the purchase were being made as a buy-out under Section 11.5.1, 11.5.2 or 11.5.3, whichever may be applicable, and such Member (or its Affiliate) must pay fair market value (or 85% in cases of default) for the business.

 11.5. Buy-Out-Procedures. 
 11.5.1. Buy-Out on Default. If an election is made by a Member to terminate the Joint Venture pursuant to Section 11.1.3 above, that Member may also elect, by written notice given
within ninety (90) days of the date of the election to terminate, to continue the business of the Joint Venture. In such event the electing Member shall purchase the other Member’s interest in the Joint Venture for an amount equal to
eighty-five percent (85%) of the fair market value of the other Member’s interest. 
 11.5.2. Buy-Out on
Elective Dissolution, If an election is made by a Member (the “Terminating Member”) to terminate the Joint Venture pursuant to Section 11.1.2, the other Member may elect, by written notice given within 90 days of
the date of the election to terminate, to continue the business of the Joint Venture. In such event, the acquiring Member shall purchase the Terminating Member’s interest in the Joint Venture for an amount equal to one hundred percent
(100%) of the fair market value of the Terminating Member’s interest. 

  
 27 









 11.5.3. Buy-Out on Mutual Agreement. If the Joint Venture is terminated
pursuant to Paragraph 11.1.1 above, either Member may elect, by written notice given within ninety (90) days of the date of termination, to continue conducting the business of the Joint Venture. Unless the Members otherwise agree, the
acquiring Member shall purchase the Terminating Member’s interest in the Joint Venture for an amount, equal to one hundred percent (100%) of the fair market value of the Terminating Member’s interest. 

11.5.4. Fair Market Value – Mutual Agreement. In case of elections under Section 11.5.1, 11.5.2 or 11.5.3,
hereinabove, the Members shall use their best efforts to agree as to the fair market value of the Joint Venture. If the Members fail to agree on such fair market value within sixty (60) days following the election by a Member to continue the
Joint Venture, fair market value shall be determined pursuant to Section 11.5.5. 
 11.5.5. Fair Market Value –
Third Party Determination. (a) If the Members cannot agree upon the fair market value for the business of the Joint Venture, then an investment banker shall be retained by the Members to make such determination. All fees payable to the
investment banker shall be split according to the Members’ interest in the Venture, 
 (b) The Members shall maintain a list
of investment bankers which both Members reasonably agree are acceptable to provide an accurate and fair calculation of the fair market value of the business. If it is necessary to select an investment hanker to determine fair market value, the
Members shall meet and attempt to agree upon the investment banker to be used. If the Members cannot agree upon the investment banker, then the investment banker shall be chosen by lot from the list of investment bankers maintained by the Members.
The above notwithstanding, unless both Members agree after full disclosure, in no event shall the investment banker to be selected either (i) be currently performing services for one of the Members or its Affiliates other than of a nominal
nature; or (ii) have, during the five years prior to the calculation of Fair Market Value, received fees in the aggregate amount of $100,000 or more from the Member or its Affiliates. 

  
 28 









 (c) Once the investment banker has been selected, it will determine what it believes to be
the fair market value of the business of the Joint Venture using whatever method or methods it deems appropriate. The value determined by the investment banker shall be referred to as the “IB Value”. 

(d) The fair market value of the business of the Joint Venture shall then be calculated according to the following: 

(i) If the IB Value and the Formula Value (as defined below) are within a range of plus or minus 10%, the greater of the IB Value or the
Formula Value shall be deemed to be the fair market value of the Business, 
 (ii) If the range between the IB Value and the
Formula Value is greater than plus or minus 10%, then a second investment banker shall be chosen by the Members pursuant to the procedures set forth in paragraphs (a) and (b) above to review the work of the first investment banker and to
make its own determination of the Fair Market Value of the Business. If the second IB Value is within plus or minus 10% of the first IB Value, the average of the two IB Values shall be deemed the Fair Market Value of the Business. If the second IB
Value is greater than plus or minus 10% of the first IB Value, then a third investment banker shall be selected according to the procedures set forth in paragraph (b) above, and the middle of the three IB Values shall be deemed to be the Fair
Market Value of the Business. 
 (e) The “Formula Value” of the Business shall mean the value of the business
calculated in accordance with the valuation model set forth as Exhibit 11.5.5 hereto. 
 11.5.6. All Relevant
Factors. In determining fair market value of the business Joint Venture, the investment banker shall take into account all relevant factors. Each Member may supply the investment banker a list of or information on those factors which the
Member believes might add to or detract from the fair market value of the business of the Joint Venture as it will be continued by the Member who has made such election to continue. 

11.6. Operations Pending Liquidation/Buy-Out. Each Member shall continue to use best efforts to operate the Joint Venture
as a going business until liquidation or buy-out. 

  
 29 









 11.7. Continuing Sales Representation. If a party other than an Armstrong
Member Corporation is to continue to operate the business of the Joint Venture, Armstrong agrees to continue to sell Grid for such entity pursuant to the Sales Representation Agreement, at the fee arrangement last in place, for a minimum period of
time after termination of the Joint Venture, if such entity requests. Such minimum period shall be (i) three years if WVI continues the business and (ii) one year if a third party continues the business. In addition, Armstrong agrees to
transfer or otherwise make available to the Joint Venture, whenever the sales representation by Armstrong is to end (whether at the end of the minimum period or before such time) a sufficient number of sales employees who had been selling Grid so as
to provide reasonable coverage of the accounts being sold and the territories where the Joint Venture’s Grid is being sold. The parties acknowledge that customer lists, contracts, advertising and marketing information, and similar items are
property of the Joint Venture. 
 11.8. Transition Period. In the event there is a termination of the Joint
Venture and either of the Members will continue the business of the Joint Venture, the party who will not be continuing the business of the Joint Venture agrees to continue providing services it had otherwise provided to the Joint Venture for a
period not to exceed six months (or such longer period of time as may be provided elsewhere in this Agreement or in Related Agreements) as may be necessary in order to permit a smooth transition. 

11.9. Necessary Approvals. The provisions as to liquidation of the Joint Venture and the purchase of the business of the
Joint Venture shall be subject to any necessary governmental approvals, and the Members shall agree upon such reasonable extensions of time with respect to such provisions as may be reasonably necessary in order to obtain any such approvals.

 11.10. Termination or Dissolution Prior to Effective Date. In the event the Joint Venture Agreement is
terminated prior to the Effective Date, then neither Member shall contribute their Current Grid Business to the Joint Venture and each Member shall have refunded to it any cash contribution made to the Joint Venture. In such a case, the liquidation
and buy-out provisions contained in Sections 11.4 and 11.5 hereof shall not be applicable, it being intended that each party will retain its own Current Grid Business.

 ARTICLE 12 
 Relationship between the Members and the Venture 
 12.1.
Competition. 
 12.1.1. Acknowledgement of Business Situation. Each Member acknowledges that it and its
Affiliates now are and/or hereinafter may be engaged in other businesses. The Members agree that neither Member shall be required to bring any business opportunities to the attention of the other Member or the Joint Venture, provided, however, that
the Members must bring any business opportunities relating to the production and sale of Grid to the attention of the Joint Venture. 
 12.1.2. Non-Competition in Grid. Each Member, on behalf of itself and its Affiliates, expressly agrees that it, and they, will not compete with the Joint Venture in the production or sale of
Grid anywhere in the World, inasmuch as it is the specific intent of the Members and their Affiliates that this Joint Venture shall be the sole vehicle for their production and sale of Grid throughout the World. The non-competition restrictions set
forth in this Section shall apply to the Members and their Affiliates until such time as the Joint Venture is dissolved, and, if the business of the Joint Venture is continued by either Member Group or a third party, for a period of five years after
the dissolution of the Joint Venture (or, if shorter, until such business is discontinued). 
 12.1.3. European
Business. It is the current intention of the Members to construct, equip, acquire and/or otherwise obtain or have available a facility which will manufacture Grid for the European market and to make a commitment to proceed therewith within
24 months from the Effective Date. Based upon this intention, it has been agreed that AVI will contribute Armstrong’s European Grid business to the Joint Venture at the Effective Date. If WVI fails to commit its share of the necessary
capital, within 24 months from the Effective Date, in order to permit the Joint Venture to construct, equip, acquire, or otherwise obtain or have available a manufacturing facility to supply grid to the European market, then it is agreed that
the Grid business being conducted by the Joint Venture in Europe will cease to be part of the Joint Venture and will be returned to Armstrong. In such event, after the European business is returned to Armstrong, Armstrong shall be free to
manufacture and sell grid in Europe (but such Grid shall only be sold in Europe), for its own account and not as part of the Joint Venture. If the European Grid business is returned to Armstrong in accordance with the foregoing, then the parties
agree that any profits or losses which have been incurred by the Joint Venture from the European business from the Effective Date until the time such business is returned to Armstrong, shall be for the account of Armstrong. In order to accomplish
this, the Joint Venture shall pay to AVI the aggregate net profit on the European Grid business during such time, or if there is a net loss, AVI shall pay to the Joint Venture the amount of the aggregate net loss on the European Grid business during
such time. In the event Armstrong has not acquired or otherwise obtained a manufacturing facility to serve the European market after the European Grid business is returned to it, the European business of Armstrong shall be returned to the Joint
Venture at such time as the Joint Venture constructs, equips, acquires or otherwise obtains or has available a manufacturing facility to produce Grid for Europe. 

  
 31 









 12.1.4. Dealing with Joint Venture. Nothing in this Agreement shall be
construed to prevent a Member, or its Affiliates, or any entity in which a Member or its Affiliates shall have an interest, from dealing with the Joint Venture in good faith as vendor, customer or, otherwise in a manner not specifically covered by
this Agreement, provided the Member or entity shall have given notice of such interest to the Board of Directors and the Board of Directors has approved or ratified such dealing. 

12.2. Relation to General Partnership Law. To the extent the provisions of this Agreement are inconsistent with the General
Partnership Law as it relates to the Joint Venture, the provisions of this Agreement shall apply. In particular, but not in limitation of the foregoing, the Members agree that neither Member shall be required to bring any business opportunities to
the attention of the other Member, except as provided in Section 12.1.1. 
 12.3. Members’ Actions. No
Member shall do anything whereby the capital or the property of the Joint Venture may be attached, taken in execution, or otherwise impaired, and each Member punctually shall pay its separate debts and indemnify the other Member against any losses
or damages incurred as a result of separate debts of the Member. Any expenses incurred by the Joint Venture in defending or meeting obligations of an individual Member shall be chargeable to that individual Member. 

  
 32 









 12.4. Limitation on Member’s and Director’s Authority. 

12.4.1. Except as specifically authorized herein or in an agreement executed concurrently herewith, neither Member nor any Director
shall have any authority to act, and neither Member nor any Director shall act or hold itself out as having authority: (a) to act as agent of the Joint Venture in any matter; or (b) to convey any interest in any property of any kind,
without regard to who holds title thereto, which is used in the conduct of the Joint Venture, in either case unless the Board of Directors delegates specific authority to the Member or Director to act as agent for the Joint Venture in the particular
matter. 
 12.4.2. Unless otherwise provided herein or in an agreement executed concurrently herewith, no Member or
Director, without the prior written consent of the Board of Directors, shall draw, accept or endorse any bill of exchange or promissory note on account of the Joint Venture, compromise any claim of the Joint Venture, for any reason, or confess
judgment against the Joint Venture, 
 12.5. Use of Name. Neither Member shall have the right to use the name of
the Joint Venture or any similar variation of such name in connection with any product, service or business without the written consent of the other Member. 
 12.6. Enforcement. A Member shall be entitled to enforce any rights of the Joint Venture against the other Member (or an Affiliate thereof) without the consent of such other Member.

 ARTICLE 13 
 Dispute Resolution 
 13.1. Initial Procedure. Any,
claim, dispute, difference or controversy arising out of or relative to this Agreement or the operation of the Joint Venture which cannot be settled by mutual understanding between the parties, shall be initially submitted to a member of the
Executive Committee of AWI, or his delegate, on behalf of AVI and a member of the Executive Committee of Worthington Industries, Inc. or his delegate, on behalf of WVI. The said persons shall promptly meet and use their best efforts to resolve the
claim, dispute, difference or controversy. Such persons shall also determine whether or not they wish to retain the services of an independent mediator to assist in resolving such dispute.
