The Parties may, and may direct the Company to, disclose the existence of the transactions contemplated by this Agreement to key employees of the Company that have been advised of the confidential nature of this Agreement and have agreed to be bound by the terms of the Confidentiality Agreement. Following a public announcement of this Agreement by the Parties in accordance with this Section 4.1, the Parties may, and may direct the Company to, disclose the existence of the transactions contemplated by this Agreement to all employees of the Company and solely in response to inquiry, disclose the existence of the transactions contemplated by this Agreement to the Company’s customers and vendors. Section 4.2 Cooperation. Seller and Purchaser shall each cooperate with and use commercially reasonable efforts to obtain the approval of DOJ and any other Governmental Authority of Purchaser as an acceptable purchaser of the Interests, and each Party shall produce all documents requested by, and provide responses to any questions from, such Governmental Authorities. Purchaser shall, as promptly as practicable after the date hereof (to the extent Purchaser has not already completed the following activities), (i) prepare and furnish all necessary information and documents reasonably requested by the DOJ and any other Governmental Entity;

6 120761002 (ii) use commercially reasonable efforts to demonstrate to the DOJ and any other Governmental Entity that Purchaser is an acceptable purchaser of the Interests; and (iii) subject to the Purchase Price adjustment set out in Section 1.3, accept modifications to the term of the Restricted Period requested by the DOJ and any other Governmental Entity in connection therewith (a “Restricted Period Modification”), provided that the Restricted Period shall in no event be less than two (2) years without consent of Purchaser, which may be withheld in Purchaser’s sole discretion. Nothing in this Agreement shall prevent Seller from complying with the DOJ Consent and Seller shall not be considered in breach of this Agreement for taking any actions to comply with the DOJ Consent; provided, however, that in the event that DOJ or any other Governmental Authority requests or requires changes to the terms of this agreement that impose materially adverse obligations, conditions or terms on Buyer or its Affiliates prior to approval, then Purchaser shall have the sole right to determine whether to and the manner in which to implement the requirement of such Governmental Authority. Purchaser and Seller shall consult and agree on strategy and communications with the DOJ and any other Governmental Entity, and, to the extent not prohibited by Law, the DOJ, or any other Governmental Entity, Purchaser shall not independently communicate with or make submissions to the DOJ or any other Governmental Entity related to the approval of Purchaser as a suitable buyer of the assets without giving Seller (i) prior notice of such communications and (ii) the opportunity to attend or participate in the communication (provided that Seller shall not be entitled to receive confidential information, including financial, about Purchaser, its Affiliates, or the Company in connection with such participation). Purchaser shall promptly notify Seller of any communications Purchaser or its Affiliates receive from any Governmental Entity relating to the transactions contemplated by this Agreement and permit Seller to review in advance any proposed communications by or on behalf of Purchaser or any of its Affiliates to any Governmental Entity, unless the staff of such Governmental Entity requires otherwise; provided, however, that Seller shall not be entitled to review or have access to Purchaser’s business plan or Purchaser’s other competitively sensitive information. Section 4.3 Further Assurances. After Closing, Seller and Purchaser each agree to take such further actions and to execute, acknowledge and deliver all such further documents as are reasonably requested by the other for carrying out the purposes of this Agreement or of any document delivered pursuant to this Agreement. Section 4.4 Member Distributions. From the date of this Agreement until the Closing Date, Purchaser shall cause the Company to continue to make distributions to its members in the ordinary course of business and consistent with past practice, subject to compliance with the LLC Agreement; provided that any distributions relating to any period on or prior to the Closing Date may be paid after the last day of such period (i.e., the Closing Date). For the avoidance of doubt, the proceeds of the conveyance of real property under Section 4.8 shall be retained by the Company, and no portion of such proceeds shall be distributed to Seller. Section 4.5 Director and Officer Liability; Indemnification. (a) Survival of Indemnification. If the Closing occurs, Purchaser shall cause all rights to indemnification and all limitations on liability existing in favor of any existing or prior employee, agent, officer, director or manager of Seller or any of its Affiliates (collectively, the “Seller Indemnitees”), as provided in the organizational documents of the Company or otherwise in effect on the date of this Agreement, and to the extent arising out of or related to the period prior

7 120761002 to Closing, to survive the consummation of the transactions contemplated hereby and continue in full force and effect and be honored by the Company after the Closing until the sixth (6th) anniversary of the Closing Date. (b) Tail Insurance. In connection with, and without limiting the foregoing, Purchaser shall, or shall cause the Company to maintain, without lapse, directors’ and officers’ liability insurance covering the Seller Indemnitees for claims or liabilities arising from facts or events occurring prior to and including the Closing Date and providing coverage not less favorable than that provided by such insurance maintained by or on behalf of the Company as of the date of this Agreement. Section 4.6 Tax ▇▇▇▇▇▇▇.▇▇▇ Returns. Purchaser shall prepare, or cause to be prepared, and timely file, or cause to be timely filed (in a manner consistent with practices followed in prior taxable periods except as required by applicable Law), all Tax Returns related to the Company, and its assets and business operations. Purchaser shall deliver to Seller, for its review and approval (which shall not be unreasonably withheld, conditioned or delayed), a draft of any such Tax Return (together with all supporting documentation and workpapers) at least twenty (20) days before the date on which such Tax Return is required to be filed, or as soon as reasonably possible if such Tax Return is required to be filed within ninety (90) days following the Closing Date. (b) No Amendments of Tax Returns; No Election Changes. Purchaser shall not amend, refile or otherwise modify, or cause or permit to be amended, refiled or otherwise modified, any Tax Return filed by the Company for any period prior to the Closing Date without the prior written consent of Seller, which shall not be unreasonably withheld, conditioned, or delayed. Except as required by applicable Law, Purchaser shall not, and shall cause the Company not to (i) make, change or revoke any Tax election that has retroactive effect to any period prior to the Closing Date or that would otherwise adversely affect Seller, or (ii) enter into a voluntary disclosure or similar agreement, or otherwise voluntarily disclose information to, a Taxing Authority with respect to any period prior to the Closing Date, in each case without Seller’s prior written consent. (c) Gains and Losses on Real Property Sale. Gains and losses for book and Tax purposes allocable to the sale of real property under Section 4.8 shall be allocated between Purchaser and Seller, as members of the Company, in accordance with the operating agreement of the Company and consistent with past practice; provided, however, that Purchaser agrees to indemnify Seller for any additional Taxes payable by Seller or other adverse tax consequences to Seller resulting from the sale of such real property, in each case as compared to the tax consequences to Seller from the sale of the Interests without the sale of such real property. Section 4.7 Post-Closing Access. Purchaser, for a period of seven (7) years following the Closing, shall, or shall cause the Company to provide Seller, its Affiliates, and their respective officers, employees and representatives with access, during normal business hours, to all books and records to the extent relating to Taxes of Seller for review and copying at Seller’s expense and to the Company’s, and their Affiliates’ personnel for the purpose of discussing any such matter or claim. Section 4.8. Real Property Sale. As soon as reasonably practicable after the date of

8 120761002 this Agreement, Purchaser shall cause to be drafted special warranty deeds (or the equivalent under local law) (“Deeds”), pursuant to which the Company will convey to Purchaser or its permitted assigns all of the Company’s right, title, and interest in and to each parcel of real property owned by the Company described on Schedule 4.8. Seller and Purchaser shall cause the Company to execute and deliver the Deeds to Purchaser’s counsel, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, at the address set out in Section 9.4, to be held in escrow, prior to Closing. At Closing, Purchaser shall remit to the Company the sum of Thirty Million Dollars ($30,000,000), which will be allocated among the properties in Purchaser’s sole discretion, as consideration for the conveyance under the Deeds. The payment of such sum shall be separate from and shall not reduce the Purchase Price. Upon confirmation from the Company that such sum has been received, and from each of Seller and Purchaser that all conditions to Closing for the benefit of such party under this Agreement have been satisfied or waived (other than conditions that are to be satisfied at Closing) and that such Party is prepared to proceed to Closing hereunder, ▇▇▇▇▇▇▇▇▇’s counsel shall release the Deeds from Escrow to Purchaser immediately prior to Closing hereunder. In the event that the Deeds have been delivered in escrow, but Closing does not occur within five (5) Business Days of the then scheduled Closing, Purchaser’s counsel shall return the Deeds to Company, unless otherwise jointly instructed by the Parties. If a new Closing date is scheduled, Purchaser and Seller shall cause the Company to re-deliver the Deeds to Purchaser’s counsel, to be held in escrow pursuant to this Section 4.8. Purchaser’s counsel has acknowledged this Agreement solely to consent to the provisions of this Section 4.8. ARTICLE V CLOSING Section 5.1 Time and Place of Closing.

Each Party agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that (x) the other Party has an adequate remedy at law or (y) an award of specific performance is not an appropriate remedy for any reason at law or equity. For the avoidance of doubt, each Party further agrees that (i) by seeking the equitable remedies provided for in this Section 9.2, such Party shall not in any respect be deemed to waive its right to seek at any time any other form of relief that may be available to such Party in accordance with this Agreement in the event that this Agreement has been terminated or in the event that the equitable remedies provided for in this Section 9.2 are not available or otherwise are not granted, and (ii) nothing set forth in this Section 9.2 shall require a Party to institute any proceeding for (or limit such Party’s right to institute any proceeding for) specific performance under this Section 9.2 prior to or as a condition to exercising any termination right under Article VIII, nor shall the commencement of any legal proceeding pursuant to this Section 9.2 or anything set forth in this Section 9.2 restrict or limit a Party’s right to terminate this Agreement in accordance with the terms of Article VIII or pursue any other remedies otherwise available under this Agreement.

4 120768324 2.4 The Restricted Parties and the Company have examined in detail this Agreement and agree that the restraints imposed upon the Restricted Parties are reasonable in light of the legitimate interests of the Company, and are not unduly harsh upon either Restricted Party’s function as a company with respect to its remaining areas of business., 3. INJUNCTIVE RELIEF. The Restricted Parties acknowledge that the remedies at law for any breach or threatened breach of any restrictive covenant contained in this Agreement will be inadequate and that the Company is entitled to seek injunctive relief to prevent breaches of this Agreement and to enforce specifically the terms and conditions of § 2 in addition to any other remedy to which the Company may be entitled at law or equity. 4. REVIEW BY COUNSEL. The Restricted Parties understand the nature of the burdens imposed by the restrictive covenants contained in this Agreement. The Restricted Parties acknowledge that they are entering into the Agreement on their own volition as a condition to the consummation of the transactions contemplated by the Purchase Agreement, and that they have been given the opportunity to have this Agreement reviewed by legal counsel. 5. RESTRICTIVE COVENANTS OF THE ESSENCE/VIOLATIONS. The restrictive covenants set forth herein are of the essence of this Agreement and the Purchase Agreement; they shall be construed as independent of any other provision in this Agreement or the Purchase Agreement; and the existence of any claim or cause of action of a Restricted Party against the Company or the Purchaser, whether predicated on this Agreement or not, shall not constitute a defense to the enforcement by the Company of the restrictive covenants contained herein. 6. ASSIGNABILITY. This Agreement shall not be terminated by the merger or consolidation of a Restricted Party or any of its Affiliates with any corporate or other entity or by the transfer of all or substantially all of the assets of the Restricted Party or any of its Affiliates to any other person, corporation, firm or entity. The provisions of this Agreement shall be binding on and shall inure to the benefit of any successor in interest to or assign of each Restricted Party and/or any of its Affiliates. 7. SEVERABILITY. The provisions of this Agreement are severable and the invalidity of any one or more provisions shall not affect the validity of any other provision. In the event that a court of competent jurisdiction shall determine that any provision of this Agreement or the application thereof is unenforceable in whole or in part because of the duration or scope thereof, the Parties agree that said court in making such determination shall have the power to reduce the duration and scope of such provision to the extent necessary to make it enforceable, and that the Agreement in its reduced form shall be valid and enforceable to the full extent permitted by law.

5 120768324 8. AMENDMENT; WAIVER. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by all of the Parties. No waiver by any Party of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be effective unless explicitly set forth in writing and signed by the party so waiving, nor shall it be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence. 9. ATTORNEYS’ FEES. In any action to enforce the restrictive covenant in § 2.1, above, the non-prevailing Party shall pay, indemnify, and save the prevailing Party harmless against all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by the prevailing Party with respect to enforcement of its rights under this Agreement. 10. GOVERNING LAW AND JURISDICTION. 10.1 This Agreement shall be governed by and construed in accordance with the domestic laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. 10.2 Each of the Parties submits to the jurisdiction of any state or federal court sitting in Wilmington, Delaware, in any action or proceeding arising out of or relating to this Agreement and agrees that all claims in respect of the action or proceeding may be heard and determined in any such court. Each of the Parties waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety, or other security that might be required of any other Party with respect thereto. Each Party agrees that a final judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by law or in equity. 11.

WHEREAS, CP&P is the owner of certain reinforced concrete elliptical pipe forms and the necessary ancillary parts (including, without limitation, headers, pallets and vibrators) for the proper production of reinforced concrete elliptical pipe (the “Forms”) that are used in operations at CP&P’s Chesapeake, Virginia and Jessup, Maryland plants (collectively, “CP&P Plant”); and WHEREAS, FP&P is the owner of certain Forms that are used in operations at FP&P’s Columbus, Ohio plant (the “FP&P Plant”, and collectively with the CP&P Plant, each, a “Plant”); WHEREAS, in connection with that certain Membership Interest Purchase Agreement, by and between FP&P and Eagle Corporation, a Virginia corporation, dated November 24, 2021 with respect to the sale of membership interests in CP&P (the “Purchase Agreement”), each Party desires to lease to the other Party, and each Party desires to lease from the other Party, the Forms from time to time, pursuant to the terms set forth herein. NOW, THEREFORE, in consideration of the terms and provisions set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 1. Defined Terms. As used herein, the “Lessor” shall mean the Party leasing a Form to the other Party, and the “Lessee” shall mean the Party leasing a Form from the Lessor. Capitalized terms used but not defined herein will have the respective meanings given them in the Purchase Agreement. 2. Rental of Forms. Subject to the terms, conditions and provisions herein, each Party hereby agrees to make available to and lease to the other Party the Forms used in such Party’s Plant for use by the other Party in the other Party’s Plant during the Term (as defined below), each in accordance with an individual written request (each, a “Rental Request”). Each Party hereby agrees to take and rent from the other Party, the Forms, upon such Party’s demand from time to time and in accordance with the terms and conditions set forth herein (each a “Rental”). 2. Rental Requests; Duration of Rental. Each Rental Request shall set forth (a) the requested rental term for the particular Forms (the “Rental Period”), which shall (i) commence on the date the Form or Forms are received by Lessee and (ii) shall be no shorter than the time necessary to complete the project or projects indicated in the Rental Request (as determined in the Lessee’s sole discretion); and (b) the type and quantity of Forms to be leased and a general description of the projects for which the Forms will be used. The Lessor shall, within five (5) Business Days of receipt of any Rental Request, either confirm availability of the Forms for the Rental Period or identify the first date as soon as practicable thereafter on which the Forms

120764201v6 requested in the Rental Request will be available for the Rental Period; provided, however, that the Lessor shall deliver the Form or Forms indicated in the Rental Request within twenty (20) Business Days of the date of the Rental Request for Forms; provided, however, the Lessor shall not be responsible for delays caused by the delivery service. 3. Forms Available to Lessee. Notwithstanding anything to the contrary set forth herein, Lessee shall not be entitled to: (i) lease any forms or ancillary parts of the Lessor other than the Forms in existence and in working and transportable condition on the date of the applicable Rental Request, and not being used or reasonably anticipated to be used by the Lessor during the applicable Rental Period; (ii) rent any Forms to the extent such Lessee has Forms in its possession or control that are functionally equivalent to those set out in any Rental Request; or (iii) use any Form rented hereunder at a location other than the Lessee’s Plant. For the avoidance of doubt, nothing in this Agreement shall obligate the Lessor to purchase or otherwise acquire any forms or ancillary parts from any third party or from any plant of Lessor or any of its affiliates, other than the Lessor’s Plant. 4. Rental Fee; Freight Costs. The Lessee shall pay to the Lessor a rental fee equal to $1.00 per Rental (“Rent”). In addition, the Lessee shall be responsible for fifty percent (50%) of any (a) applicable sales, use or other taxes, custom charges or duties on the lease and use of such Forms, and (b) all transportation costs, loading or unloading charges or related fees associated with the shipment and transfer (delivery and return) of Forms between the Parties (collectively, the “Additional Charges”). A Form will be considered in possession of the Lessee from the date such Form is received by the Lessee until the date that the Form is delivered to the shipping or transportation company for delivery back to the Lessor (freight collect). Rent will be due and payable on the last day of each month for all Forms in the possession of the Lessee during such month. In addition, Additional Charges will be invoiced monthly and shall be due and payable no later than thirty (30) days after the date of invoice. 5. Condition of Leased Forms. The Lessee shall accept the Forms in their “as-is” condition, without warranty or representation of any kind and Lessor shall have no obligation to replace or repair any Forms. THERE ARE NO IMPLIED WARRANTIES OF ANY KIND IN CONNECTION WITH THE LEASE OF THE FORMS, INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. 6. Use and Maintenance of Leased Forms. During the Term, the Lessee may use the Forms for the projects described in the applicable Rental Request and covenants and agrees to maintain the Forms in good working order and condition, ordinary wear and tear and casualty excepted. 7. Default. If either Party defaults in any material respect in the performance of, or compliance with, any term or condition hereof, the non-defaulting Party may terminate the Agreement, and Lessor may reclaim the Forms. Notwithstanding the foregoing, the defaulting Party shall be given twenty (20) Business Days prior written notice of any default or breach, and the non-defaulting Party may not terminate the Agreement if, within twenty (20) Business Days of receipt of such notice, the defaulting Party has corrected the default or breach or taken action reasonably likely to effect such correction within a reasonable time.

120764201v6 8. Indemnification. The Lessee shall indemnify, defend and hold harmless the Lessor and its affiliates against any and all losses, costs, expenses and other damages incurred by the Lessor or its affiliates relating to or arising from the Lessee’s use, maintenance or repair of the Forms or breach or non-fulfilment of this Agreement. Lessee’s obligations to indemnify the Lessor and its affiliates does not extend to any losses, costs, expenses or other damages that arise out of the gross negligence or misconduct of the Lessor. The Lessor shall indemnify, defend and hold harmless the Lessee and its affiliates against any and all losses, costs, expenses and other damages incurred by the Lessee or its affiliates relating to or arising from the Lessor’s breach or non- fulfilment of this Agreement.

Term. The term of the Agreement shall commence on the Effective Date and continue for a period of eighteen (18) months. 10. Assignment. Neither Party may assign its rights under this Agreement without the prior written consent of the other Party. Any purported assignment of this Agreement to which consent has not been obtained shall be voidable at the option of the non-consenting Party. 11. Subordination. Each Party agrees to subordinate this Agreement to any security interest that the other Party has placed or may hereafter place upon the Forms owned by such Party. 12. Notices.
