Calculation Statement shall become final and binding on the parties on the 30th calendar day following receipt thereof by the Seller Representative unless the Seller Representative delivers written notice of its disagreement (a “Notice of
Disagreement”) to Acquiror prior to such date. Any Notice of Disagreement shall specify the items set forth on the Final Purchase Price Calculation Statement with which the Seller Representative disagrees and the Seller

differences they have with respect to any matter specified in the Notice of Disagreement and (ii) the date any disputed amounts are finally determined in accordance with the balance of this paragraph. During the 30-day period following the

 9 








 
Notice of Disagreement, the Seller Representative and Acquiror shall seek in good faith to resolve in writing any differences which they may have with respect to any amount specified in the
Notice of Disagreement or identified by the Seller Representative during said 30-day period. If, at the end of such 30-day period, the Seller Representative and Acquiror have not reached agreement on such amounts, the amounts which remain in dispute
shall be recalculated by an independent accounting firm (the “Independent Accountant”). The Independent Accountant shall be Ernst & Young or, if such firm is unable or unwilling to act, such other independent public
accounting firm as shall be agreed in writing by the Seller Representative and Acquiror. The Independent Accountant shall make a ratable allocation of its charges between the parties for such work as a part of its determination based on the inverse
proportion by which the amount in dispute was determined in favor of one party over the other. Any amounts so recalculated shall be final and binding on the parties. 
 (c) If the Closing Date Companies Purchase Price, as calculated pursuant to this Section 2.12, exceeds (such excess amount, the “Excess”) the Estimated Purchase Price,
then Acquiror shall cause to be paid to the Equity Interest Sellers their respective Closing Share of an amount equal to the Excess to their respective Designated Accounts. The respective Closing Shares of the Colorado Sellers and the Alleyton
Sellers shall reflect the relative proportion of (i) the change in Colorado Cash as set forth in the Estimated Purchase Price Calculation Statement as compared to that set forth in the Final Purchase Price Calculation Statement and
(ii) the change in Closing Cash other than Colorado Cash as set forth in the Estimated Purchase Price Calculation Statement as compared to that set forth in the Final Purchase Price Calculation Statement. 

(d) If the Closing Date Companies Purchase Price, as calculated pursuant to this Section 2.12, is equal to the Estimated
Purchase Price, then no further payment shall be due to either Acquiror or the Equity Interest Sellers under this Section 2.12. 
 (e) If the Closing Date Companies Purchase Price, as calculated pursuant to this Section 2.12, is less than the Estimated Purchase Price (the amount of such difference, the
“Deficiency”), then an amount equal to such Deficiency shall be paid by the Equity Interest Sellers to Acquiror.

designated in writing by the Acquiror or the Designated Accounts, as the case may be. 
 SECTION 2.13 Allocation of
Purchase Price. The Sellers and Acquiror understand and agree that the transactions contemplated hereunder shall be treated by the Sellers as fully-taxable sales of membership interests in Alleyton, membership interests in Colorado and
assets of BSI and as asset purchases by Acquiror and Alleyton for U.S. federal income tax purposes. For all tax purposes, the Sellers shall allocate the consideration payable pursuant to this Agreement (including any amounts payable after the
Closing Date and any adjustments thereto) plus the amount of liabilities treated as assumed for U.S. federal income tax purposes among the assets of the Companies and the BSI Properties in accordance with Schedule 2.13. The Sellers and
Acquiror shall report, act, and file tax returns (including, but not limited to, IRS Form 8594) in all respects and for all purposes consistent with the allocation set forth on Schedule 2.13 and shall not take any position (whether in audits,
tax returns, or otherwise) that is inconsistent with the foregoing, except as otherwise required by Law. All indemnification payments made pursuant to this Agreement by one party to another party (other than interest payments) shall be treated by
such parties as an adjustment to the consideration payable pursuant to this Agreement, to the extent permitted by Law. 

SECTION 2.14 Different Consideration. Each Equity Interest Seller understands, acknowledges and agrees that the form(s),
amount(s) and timing of payment(s) of consideration to be paid 

  
 10 









 
to such Equity Interest Seller pursuant to this Agreement in reliance on the representations, warranties, covenants and agreements of the Equity Interest Seller contained herein and in
consideration of the sale, conveyance, assignment, transfer and delivery of the Equity Interests and compliance with the terms hereof, including non-compete covenants, may differ from the form(s), amount(s) and timing of payment(s) of consideration
to be paid to any other Equity Interest Seller pursuant to this Agreement and that all of such differences are known and agreed and each Equity Interest Seller shall have no claims against any party with respect thereto or defenses for enforcement

the Buy-Sell Agreements that will be validly terminated prior to Closing. The Equity Interest Sellers are not party to any contract, other than this Agreement, that could require them to sell, transfer or otherwise dispose of any of the Equity

or Acquiror with respect to the Transactions.

Schedule 3.12(a) is correctly categorized as either a Pension Plan or a Welfare Plan.

to Acquiror true and correct copies of the following: 
 (i) each ERISA Plan listed on Schedule 3.12(a) and all amendments
thereto;

of ERISA. 
 (d) There is no action, suit or claim pending (other than routine claims for benefits) or that reasonably could be
expected to be asserted against any ERISA Plan or the assets of any ERISA Plan. No civil or criminal action brought pursuant to the provisions of Title I, Subtitle B, Part 5 of ERISA is pending or threatened against any fiduciary of any ERISA Plan.
None of the ERISA Plans or any fiduciary thereof has been the direct or indirect subject of an audit investigation or examination by any governmental or quasi-governmental agency. 

(e) All of the ERISA Plans currently comply, and have complied in the past, both as to form and operation, with the terms of such ERISA
Plans and with the applicable provisions of ERISA, the Code and other applicable federal Laws. All necessary approvals from any Governmental Authority for the ERISA Plans have been obtained and a favorable determination or opinion letter as to the
qualification under Section 401(a) of the Code of each of the Pension Plans and of each amendment thereto has been made by the IRS and a recognition of exemption from federal income taxation under Section 501(a) of the Code of each of the
funded Welfare Plans, if any, has been made by the IRS. Nothing has occurred since the date of each such determination or opinion letter that would adversely affect such qualification or exemption. 

(f) No agreement, commitment, or obligation exists to increase any benefits under any ERISA Plan or to adopt any new ERISA Plan. The
transactions contemplated this Agreement will not restrict the right of the Companies to amend or terminate any ERISA Plan. 

(g) No ERISA Plan or Non-ERISA Plan provides for post-employment health, life insurance or other welfare benefit coverage, other than as
may be required under “COBRA” pursuant to Part VI of Title I of ERISA. 
 (h) Except as set forth on Schedule
3.12(h), no contract, agreement, plan or other arrangement, whether or not a Non-ERISA Plan or an ERISA Plan (other than this Agreement), exists pursuant to which the execution of this Agreement would trigger an obligation by the Companies to
pay any amount or provide any property to any employee, officer or director of the Companies or to accelerate the vesting of any benefit.

 (ii) except as set forth in Schedule 5.5, directly or indirectly, either for himself, herself, itself or any other Person or entity, hire any of the officers or directors or other persons employed
by the Companies, or Acquiror or its affiliates (with respect to the Business) and their respective successors or assigns, or solicit or induce such persons to leave the employ of the Companies or Acquiror or its affiliates (with respect to the
Business); 
 (iii) directly or indirectly, approach or seek business from any Customer (as defined below), refer business from
any Customer to any enterprise or business or be paid commissions based on business sales received from any Customer by any enterprise or business. For purposes of this Section 5.5, the term “Customer” means any
Person, firm, corporation, partnership, association or other entity to which the Companies, Acquiror or their affiliates or any of their successors or assigns, provided goods or services during the 36-month period prior to the time at which any
determination shall be made that any 

  
 31 









 
such Person, firm, corporation, partnership, association or other entity is a Customer. For the purposes of this Agreement, the term “affiliate” shall mean any entity
controlling, controlled by or under common control with the named party; 
 (iv) disparage the Companies, Acquiror or any of
their affiliates in any way which could adversely affect the goodwill, reputation or business relationships of the foregoing with the public generally, or with any of their customers, suppliers or employees; or 

(v) directly or indirectly, either for himself, herself, itself or any other Person or entity, acquire, or negotiate and/or enter into a
lease, royalty arrangement or similar agreement related to the development or exploitation of aggregate reserves or otherwise, relating to, the Trust Property, or render services or advice to or consult with any other Person in connection therewith.

 (b) Each of the Seller Parties acknowledges that the restrictions imposed by this Agreement are fully understood by such
Person, are fair and reasonable, and will not preclude such Person from becoming gainfully employed following the execution of this Agreement. Each Seller Party further acknowledges and agrees that the payments to be made to it pursuant to this
Agreement are sufficient consideration for its obligations under Section 5.5(a). 
 (c) If any of the provisions of
this Section 5.5 shall otherwise contravene or be invalid under the Laws of any state or other jurisdiction where it is applicable but for such contravention or invalidity, such contravention or invalidity shall not invalidate all of the
provisions of this Section 5.5, but rather this Section 5.5 shall be reformed and construed, insofar as the Laws of that state or jurisdiction are concerned, as not containing the provision or provisions, but only to the
extent that they are contravening or are invalid under the Laws of that state or jurisdiction, and the rights and obligations created hereby shall be reformed and construed and enforced accordingly. In the event of a breach or violation by any
Seller Party of this Section 5.5, Acquiror shall have the right to pursue all legal remedies provided for herein and, notwithstanding recovery of any such remedy, the Non-Compete Period as to such Seller Party shall be tolled until such
breach or violation has been cured. 
 (d) Each Seller Party acknowledges that Acquiror will have no adequate remedy at law and
may suffer irreparable damage if any of the Seller Parties breach or fail to perform any of their obligations in this Agreement, including, without limitation, Section 5.5, Section 5.6, Section 5.8 and
Section 5.13(b). Accordingly, each of the Seller Parties agrees that Acquiror shall have the right, in addition to any other rights which it may have, to specific performance and equitable injunctive relief if any of the Seller Parties
shall fail or threaten to fail to perform any of their obligations hereunder. In connection therewith, each of the Seller Parties waive the claim or defense that adequate remedy at law exists. 

(e) For the avoidance of doubt, the parties hereto agree that, other than as set forth in Section 5.5(a)(v), this
Section 5.5 does not restrict or prohibit the Seller Parties from owning, leasing or using real property for purposes other than in connection with a Business or related activities engaged in by the Companies prior to the Closing Date.
The parties hereto also agree that this Section 5.5 does not restrict Perry Glen Shepard’s ability to engage or invest in, own, manage, operate, finance or control the factoring business that he owns as of the date of this Agreement.

 SECTION 5.6 Confidentiality. 
 (a) Until the Closing Date, each of the parties shall, and shall cause its affiliates and officers, directors, principals, employees, advisors, auditors, agents and other representatives (collectively,
“Representatives”) to, keep confidential, disclose only to its 

  
 32 









 
affiliates or Representatives and use only in connection with the Transactions all information and data obtained by them from the other party or its affiliates or Representatives relating to such
other party, the Companies, the BSI Properties or the Transactions (other than information or data that is or becomes available to the public other than as a result of a breach of this Section 5.6 or that was known to such party at the
time of receipt), unless disclosure of such information or data is required by applicable Law. In the event that the Transactions are not consummated, each party shall, and shall use its commercially reasonable efforts to cause its affiliates and
Representatives to, promptly return to the other party or destroy all documents (including all copies thereof) containing any such information or data. 
 (b) For a period of seven years following the Closing Date, the Sellers shall not, and each Seller shall cause its affiliates and Representatives and its respective affiliates not to, use for its or their
own benefit or divulge or convey to any third party, any Confidential Information; provided, however, that each Seller and their respective affiliates may furnish such portion (and only such portion) of the Confidential Information as
such party reasonably determines it is legally obligated to disclose if: (i) it receives a request to disclose all or any part of the Confidential Information under the terms of a subpoena, civil investigative demand or Order issued by a
Governmental Authority; (ii) to the extent not inconsistent with such request, it notifies Acquiror of the existence, terms and circumstances surrounding such request and consults with Acquiror on the advisability of taking steps available
under applicable Law to resist or narrow such request; (iii) it exercises its commercially reasonable efforts to obtain an Order or other reliable assurance that confidential treatment will be accorded to the disclosed Confidential Information;
and (iv) disclosure of such Confidential Information is required to prevent the Seller Parties or such affiliate from being held in contempt or becoming subject to any other penalty under applicable Law. For purposes of this Agreement,
“Confidential Information” consists of this Agreement, all information and data relating to the Companies, the assets and business of the Companies and the BSI Properties (including intellectual property, customer and
supplier lists, pricing information, marketing plans, market studies, client development plans, business acquisition plans and all other information or data), and the Transactions, except for data or information that is or becomes available to the
public other than as a result of a breach of this Section 5.6. 
 (c) Effective as of the Closing, the Sellers hereby
assign to Acquiror all their respective right, title and interest in and to any confidentiality agreements entered into by them and each Person (other than Acquiror and its affiliates and Representatives) who entered into any such agreement or to
whom Confidential Information was provided in connection with any transaction involving the acquisition or purchase of all or any portion of the Companies or any of the Companies’ assets or the BSI Properties Interests. From and after the
Closing, the Sellers will take all actions reasonably requested by Acquiror in order to assist in enforcing the rights so assigned. The Sellers shall use their commercially reasonable efforts to cause any such Person to return to the Sellers any
documents, files, data or other materials constituting Confidential Information that was provided to such Person in connection with the consideration of any such transaction. 
 SECTION 5.7 Public Announcements. On and after the date hereof and through the Closing Date, the parties shall consult with each other before issuing any press release or otherwise making
any public statements with respect to this Agreement, the Ancillary Agreements or the Transactions, and none of the Seller Parties or TBGSI on the one hand or Acquiror on the other hand shall issue any press release or make any public statement
prior to obtaining the other party’s written approval, which approval shall not be unreasonably withheld, except that no such approval shall be necessary to the extent disclosure may be required by applicable Law or any listing agreement of any
party hereto or its affiliates. 

  
 33 









 SECTION 5.8 Exclusivity. 

(a) The Companies, TBGSI and the Sellers agree that between the date of this Agreement and the earlier of the Closing and the termination
of this Agreement, the Companies, TBGSI and the Sellers shall not and shall not permit any of their respective affiliates or Representatives to: 
 (i) solicit, initiate, consider, encourage or accept any other proposals or offers from any Person relating to any direct or indirect acquisition or purchase of all or any portion of the Equity Interests,
assets of the Companies, the BSI Properties or any other equity interests in the Companies, whether effected by sale of assets, sale or issuance of equity, merger, consolidation, equity exchange or otherwise, other than inventory to be sold in the
ordinary course of business consistent with past practice; or 
 (ii) participate in any discussions, conversations, negotiations
or other communications regarding, or furnish to any other Person any information with respect to, or otherwise cooperate in any way, assist or participate in, facilitate or encourage any effort or attempt by any other Person to seek to do any of
the foregoing. 
 (b) The Companies, TBGSI and the Sellers shall cease and cause to be terminated all existing discussions,
conversations, negotiations and other communications with any Persons conducted heretofore with respect to any of the foregoing. 

(c) The Companies, TBGSI and the Sellers shall notify Acquiror promptly, but in any event within 24 hours, orally and in writing if any
such proposal or offer, or any inquiry or other contact with any Person with respect thereto, is made. Any such notice to Acquiror shall indicate in reasonable detail the identity of the Person making such proposal, offer, inquiry or other contact
and the terms and conditions of such proposal, offer, inquiry or other contact. The Companies, TBGSI and the Sellers shall not release any Person from, or waive any provision of, any confidentiality or standstill agreement to which the Companies,
TBGSI or a Seller is a party or beneficiary, without the prior written consent of Acquiror. 
 SECTION 5.9 Financing.

 (a) The Companies, TBGSI and the Seller Parties shall provide Acquiror and its affiliates and Representatives with
such cooperation and assistance in connection with the arrangement of financing for the Transactions as may be requested by Acquiror, including (i) participating in meetings, presentations, due diligence sessions, drafting sessions and sessions with
prospective lenders, investors and rating agencies in connection with the financing, (ii) assisting with the timely preparation of materials for bank information memoranda, prospectuses, private placement memoranda, financial statements (including

no later than 30 days prior to the Closing Date) or, in the case of quarterly or annual financial statements that have not been delivered prior to the date hereof, by a date that is not later than 45 days after the end of the relevant fiscal quarter
in respect of unaudited financial statements or 90 days after the end of the relevant fiscal year in respect of audited financial statements) with financial statements, financial books and records, reports, projections and other information
regarding the Companies and their businesses and operations and the BSI Properties, (iv) facilitating the pledging of collateral in connection with the financing (including obtaining and delivering any pay-off letters or other cooperation in
connection with the repayment or other retirement of existing indebtedness and the release and termination of any and all related liens) on or prior to the Closing Date, (v) causing the taking of corporate actions (subject to the occurrence of the
Closing) by the Companies that are 

  
 34 









 
reasonably necessary to permit the completion of the financing, (vi) using reasonable efforts to obtain accountants’ comfort letters, surveys, environmental reports and third party consents
necessary to permit the completion of the financing, (vii) facilitating the execution and delivery (at the Closing) of guarantees, mortgages or other definitive documents relating to the financing and (viii) cooperating reasonably with
Acquiror’s and affiliates financing sources’ due diligence and with their efforts to obtain guarantees and to obtain and perfect security interests in assets intended to constitute collateral securing such financing, with such cooperation
occurring prior to or simultaneously with the Closing Date, but the execution of any guarantee or security arrangement not taking effect until the Closing Date. 
 (b) The Companies, TBGSI and the Seller Parties shall cause their legal counsel to render and provide reasonable assistance to Acquiror and Acquiror’s counsel in connection with the rendering of any
legal opinions as may be reasonably necessary in connection with the financing, in each case in customary form and of customary scope for the applicable jurisdiction and a transaction such as the financing. 

SECTION 5.10 Notice of Default of Acquiror. 
 (a) Acquiror will promptly give notice to the Seller Representative of the occurrence of any event known to Acquiror, or the failure of any event known to Acquiror to occur, that results in a breach of
any representation or warranty by Acquiror or a failure by Acquiror to comply with any covenant, condition or agreement contained herein. 
 (b) Acquiror will (i) take all actions necessary to render accurate as of the Closing Date its representations and warranties contained herein, (ii) refrain from taking any action that would
render any such representation or warranty inaccurate as of such time and (iii) perform or cause to be satisfied each covenant to be performed or satisfied by it as contemplated by this Agreement. 

SECTION 5.11 Title Documents. 
 (a) Prior to the Closing, the Companies, TBGSI and the Seller Parties will at their cost and expense (other than the cost of premiums for additional title and leasehold insurance that Acquiror requests
that they obtain at Acquiror’s cost) (i) use their good faith efforts to obtain estoppels, warranty deeds, good and marketable title, title reports, title and leasehold insurance (in form and substance satisfactory to Acquiror), correct
defects and imperfections of title and remove Encumbrances, other than Permitted Encumbrances (which term does not include any amendments or supplements to the Schedules for the purposes of this Section 5.11), for each of the parcels of
Real Property (including parcels that the Companies purport to own but may not be titled in their name as of the date hereof ), and (ii) use their good faith efforts to take such steps as otherwise may be necessary to ensure that the
Representations and Warranties of the Sellers and TBGSI set forth in Section 3.7 hereof are true and correct as of the Closing Date. If the Companies and Seller Parties fail to perform their obligations under this
Section 5.11, Acquiror shall have the right, but not the obligation, in its discretion, prior to the Closing, to satisfy these obligations and charge Seller Parties for the cost relating thereto. Notwithstanding the foregoing, the
parties agree that matters relating to title to each of the parcels of Real Property set forth on Schedule 3.7(c) as owned by Alcomat (collectively, the “Alcomat Properties”) are addressed in
Section 5.11(b), and not this Section 5.11(a). 
 (b) Prior to Closing, Alleyton will, at its cost and
expense, obtain, or cause Alcomat to obtain, a title insurance policy for each Alcomat Property with a value to be agreed on by Acquiror and the Alleyton Sellers (collectively, the “Alcomat Title Insurance Policies”). The
Alleyton Sellers will provide the title commitment for each Alcomat Title Insurance Policy to Acquiror for review, and Acquiror will notify the Alleyton Sellers of any Encumbrances set forth thereon to which Acquiror objects (collectively, the
“Alcomat Title Objections”). The Alleyton Sellers will use their good faith efforts to remove the Alcomat Title Objections from the Alcomat Title Insurance Policies prior to Closing. 

  
 35 









 (c) Prior to Closing, Alleyton will, at its cost and expense, obtain a title insurance
policy for the Owens Property with a value equal to the purchase price of the Owens Property set forth in the Owens Purchase Agreement (the “Owens Title Insurance Policy”). Prior to Closing, Acquiror will notify the Alleyton
Sellers of any Encumbrances set forth on the title insurance commitment for the Owens Property to which Acquiror objects (collectively, the “Owens Objections”). The Alleyton Sellers will use their reasonable best efforts to
remove the Owens Title Objections from the title insurance policy for the Owens Property prior to Closing. Prior to Closing, Alleyton will deliver to Acquiror a true and complete copy of the survey of the Owens Property. Acquiror will notify the
Alleyton Sellers of any discrepancies in the survey of the Owens Property to which Acquiror objects. The Alleyton Sellers will use their good faith efforts to correct such discrepancies prior to Closing. 

(d) Provided that they have used their good faith efforts, the Companies, TBGSI and the Seller Parties shall not have any liability to
Acquiror for the termination of this Agreement related to the failure to satisfy the goals of those efforts as set forth in this Section 5.11. 
 SECTION 5.12 Financial Reporting. Prior to and after the Closing, the Seller Parties shall and shall cause their affiliates and Representatives to cooperate with Acquiror in connection with,
and use reasonable best efforts to provide to Acquiror any information (including annual, quarterly, monthly and other financial statements and information related to the Companies and their businesses and operations and the BSI Properties)
reasonably requested by Acquiror in connection with, in compliance with any reasonable deadline imposed by Acquiror, Acquiror’s or any of its affiliate’s compliance with any Law or GAAP requirement applicable to it. 

SECTION 5.13 Trust Property. From the date hereof through the Closing Date, the Major Sellers will each use their
respective good faith efforts to negotiate and assist Alleyton in its efforts to enter into an agreement with RES/VLS Real Estate Limited Partnership (or its assignee) for the lease, on commercially reasonable terms, of that certain piece of real
property known as the Trust Property as more fully described on Schedule 5.13(a) hereto (the “Trust Property”); provided, however, that neither Alleyton nor any Seller Party shall enter into any lease or
acquisition agreement relating to the Trust Property without the prior written consent of Acquiror. Provided that the Seller Parties have used good faith efforts to comply with their obligations under this Section 5.13(a): none of the
Seller Parties shall have any liability to Acquiror if Alleyton does not enter into a lease for the Trust Property as contemplated by this Section 5.13(a), and the consideration to be paid under this Agreement at or after Closing shall
not be adjusted because Alleyton has not entered into such lease. 
 SECTION 5.14 Waiver of Buy-Sell Agreements.
Each Company and Equity Seller that is a party to the Buy-Sell Agreement, dated as of January 1, 2013, among Todd Barten, Perry Glen Shepard, Frank Bantle, Sr., Steve Rhodes, Johnny Cook and Alleyton or to the Buy-Sell Agreement, dated as of
January 1, 2013, among Todd Barten, Perry Glen Shepard, Steve Rhodes, Johnny Cook, Colorado and CGC (together, the “Buy-Sell Agreements”) hereby waives any rights exercisable by such Company or Equity Seller pursuant to
the Buy-Sell Agreements in connection with the Transactions. 
 SECTION 5.15 Colorado County Aggregates Reserves.
During the Non-Compete Period, upon Acquiror’s request from time to time, the Major Sellers will use their respective good faith efforts to assist Acquiror with any opportunities that may arise to acquire or “lease” aggregates in
Colorado County, Texas (any agreements for such acquisitions or leases, the “Colorado County Aggregates Reserves Agreements”). In addition, if either of the Major Sellers, directly or indirectly, either for himself or
any 

  
 36 









 
other Person, has the opportunity to negotiate and/or enter into a Colorado County Aggregates Reserves Agreement, whether or not such opportunity arose out of a request by Acquiror, the Major
Sellers will notify Acquiror of such opportunity and provide it with the details thereof. The Acquiror’s rights and Major Sellers’ obligations hereunder are in addition to the rights and obligations set forth in the Noncompete
provisions of Section 5.5 hereof and the provisions of Section 5.13 hereof regarding the Trust Lease. 

SECTION 5.16 Schedule Amendments. The Sellers and TBGSI shall (and are hereby permitted to) supplement or amend the
Disclosure Schedules so that such schedules and related representations and warranties are true and correct as soon as possible after the date hereof and in no case later than such date (the “Cut-Off Date”) as is necessary to
allow sufficient time prior to the Termination Date for financing of the Transactions contemplated by Acquiror to be secured on the basis of the final Disclosure Schedules. No such supplements or amendments to any Disclosure Schedules shall be made,
nor shall be effective even if purported to be made, on or after the Cut-Off Date. The exact date to be established for the Cut-Off Date shall be agreed by the parties hereto as soon as possible after the date hereof, subject to the mutual
reasonable consent of the parties hereto based on the time reasonably required for the Sellers and TBGSI to complete the Disclosure Schedules while allowing sufficient time prior to the Termination Date to allow the Acquiror to secure the financing
contemplated by Acquiror to fund the Transactions which the parties recognize requires finalized Disclosure Schedule. The Sellers and TBGSI shall have no liability under this Agreement whether or not the Closing occurs for any misrepresentations
made as of the date hereof that are corrected by such supplements or amendments to such Disclosure Schedules prior to the Cut-Off Date. The parties agree that the Closing Share percentages set forth on Schedule 2.9(c)(i) may be amended prior
to Closing by the Seller Representative, once the Estimated Purchase Price has been determined. 
 SECTION 5.17 Vox
Property Development. The Companies and BSI shall continue to develop the Vox Property in the ordinary course of business consistent with past practice. 
 SECTION 5.18 Brune Lease and Adjacent Property.  
 (a) Prior
to the Closing, Alleyton may transfer and assign to BSI the Brune Lease, which relates to that certain piece of real property known as the Brune Property as more fully described on Schedule 5.18(a) hereto (the “Brune
Property”). The parties hereto agree that the use of the Brune Property and the Adjacent Property following the Closing is subject to Section 5.5. Prior to the Closing, the Sellers will (i) permit Acquiror and its
Representatives to access the Brune Property and the Adjacent Property in order to test such property, including by performing intrusive studies, for the presence of aggregates and (ii) otherwise facilitate such testing. 

(b) For the purposes of this Section 5.18: 
 (i) The “Adjacent Property” means that certain piece of real property adjacent to the Brune Property as more fully described on Schedule 5.18(b) hereto. 

(ii) The “Brune Lease” means the Sand and Gravel Lease, dated August 14, 2008, between Marjorie S. Brune,
individually and as trustee of the Marjorie S. Brune Revocable Living Trust, Herman Willie Brune and Elena Brune Hollub and Alleyton. 
 SECTION 5.19 Appraisals. Upon Acquiror’s request, the Seller Parties and BSI will obtain, prior to Closing, at Acquiror’s expense, appraisals of the parcels of Real Property
designated by Acquiror from a third-party appraiser selected by Acquiror.

SECTION 6.2 Indemnification by Acquiror. Subject to the limitations set forth in this Article VI, Acquiror (the
“Acquiror Indemnifying Party” ) shall indemnify and hold harmless the Sellers and their affiliates (collectively, the “Seller Indemnified Parties”) in respect of any and all Losses, whether or not due
and payable incurred or sustained by the Seller Indemnified Parties in connection with each and all of the following, together with interest equal to the LIBOR Rate (as herein defined) on cash disbursements from the date of disbursement:

 38 









 SECTION 6.3 Limitations on Indemnification. 

(a) Threshold. Except as provided in Section 6.3(c), no Indemnified Party shall be permitted to enforce any claim for
indemnification pursuant to this Agreement based on Sections 6.1(a) or 6.2(a), respectively against any Indemnifying Party until in each case the aggregate amount of such respective claims exceeds $1,000,000 (the “Threshold
Amount”). Once claims pursuant to such respective Sections 6.1(a) or 6.2(a), as the case may be, in excess of the Threshold Amount have been asserted by such Indemnified Party against such Indemnifying Parties in the
aggregate, all such claims may be pursued, but only to the extent that such claims are above the Threshold Amount. 
 (b)
Maximum Indemnification. Except as provided in Section 6.3(c), in no event shall any Indemnifying Party be required to make indemnification payments with respect to claims based on Sections 6.1(a) or 6.2(a),
respectively, in excess of $15,000,000. 
 (c) Limitation. The limitations in Sections 6.3(a) and 6.3(b)
shall not apply to any Fundamental Claim, Fraud Claim or Tax Claim, as defined herein. In no event shall any Indemnifying Party be required to make indemnification payments under this Agreement in excess of the Total Purchase Price. 

(d) Survival. Any claim for indemnification shall survive the Closing until expiration of the applicable statute of limitations, if
any, subject to the survival periods, if any, set forth in this Section 6.3 with respect to certain of such claims; provided, however, that any claim for indemnification based upon any misrepresentation with respect to Sections
3.1, 3.2, 3.3, 3.4, 3.5, 3.7(c), and 3.24 (“Fundamental Claim”) shall survive indefinitely. In addition, any claim for indemnification shall survive the applicable termination
date, if any, set forth herein if a party, prior to such termination date, shall have advised the other party in writing of facts that constitute or may give rise to an alleged claim for indemnification, specifying in reasonable detail the basis
under this Agreement for such claim. 
 (i) Representations and Warranties. Any claim for indemnification based on
Section 6.1(a) or Section 6.2(a) other than a claim referred to in Sections 6.3(d)(ii) or 6.3(d)(iii) shall be made during the period from the Closing Date until the date that is eighteen months after the
Closing Date, after which such date, the Indemnified Parties are foreclosed from making such claims against the Indemnifying Parties. 
 (ii) Environmental Claims. Any claim based upon Section 6.1(d), or the breach by the Seller Parties of the representations and warranties set forth in Section 3.10
(“Environmental Claims”) may be made at any time prior to the third anniversary of the Closing Date, after which such date, the Indemnified Parties are foreclosed from making such claims against the Indemnifying Parties

 (iii) Claims Barred Only by the Applicable Statute of Limitations. Any claim based upon (A) any willful, grossly
negligent, fraudulent or intentional misrepresentation of any Seller contained in this Agreement, any Ancillary Agreement or any other document, list, exhibit or instrument furnished in connection herewith or therewith, including any assessment by a
taxing authority alleged to arise from a willful, false or fraudulent intent to evade taxes, or from any failure to file a return (“Fraud Claim”); or (B) taxes for which the Seller Indemnifying Parties are required to
indemnify Acquiror or from a misrepresentation of the Seller Parties with respect to Section 3.17 (“Tax Claim”), may be made until the date that such claim is barred by the applicable statute of limitations, if
any. 
 (e) Offset. The Acquiror Indemnified Parties shall have the right to set off and apply against any future payments
owed to the Seller Indemnifying Parties or any of their affiliates under Section 2.7 (Installment Payments), the amount of any indemnity claims made in good faith by the Acquiror 

  
 39 









 
Indemnified Parties against the Seller Indemnifying Parties pursuant to the provisions of this Agreement or any Ancillary Agreement. Any such set-off and application may be made by an Acquiror
Indemnified Party of the amount of any such indemnity claims and such amounts shall, without further action on the part of any party, be deemed set off and applied against any future installment payments described in Section 2.7 as
determined by the Acquiror Indemnified Party. Subject to the following sentence, the Acquiror Indemnified Parties may pursue recovery against the Seller Indemnifying Parties from other than the installment payments described in
Section 2.7 to the extent that there are or may be insufficient installment payments (as measured in the following sentence) to satisfy such claims. The parties agree that any judgment or settlement of any indemnity claim made by the
Acquiror Indemnified Parties under this Article VI shall be satisfied first by offsetting the amount of such settlement or judgment against any future payments owed to the Seller Indemnifying Parties or any of their affiliates under
Section 2.7 (Installment Payments) in accordance with Section 6.3(e); provided, that the amount to be so offset with respect to any settlement or judgment not due at the time such indemnity claim was made shall be
valued on a present value basis using a discount rate of ten percent. 
 SECTION 6.4 Defense by the Indemnifying
Parties. In connection with any claim giving rise to indemnity hereunder resulting from or arising out of any claim or legal proceeding by a Person (other than the Indemnified Parties) solely for monetary damages in a civil proceeding, the
Indemnifying Parties at their sole cost and expense, may, upon written notice to the Indemnified Parties received by the Indemnified Parties within 10 Business Days after the Indemnifying Parties’ receipt of notice of such claim, assume the
defense of any such claim or legal proceeding, provided that the Indemnifying Parties acknowledge in writing their obligation to indemnify the Indemnified Parties in respect of the entire amount of all of the claims asserted therein, subject
to the indemnity limitations hereunder . If the Indemnifying Parties assume the defense of any such claim or legal proceeding, the Indemnifying Parties shall select counsel reasonably acceptable to the Indemnified Parties to conduct the defense of
such claims or legal proceedings and, at their sole cost and expense (which costs and expenses shall not be applied against any indemnity limitation hereunder), shall take all steps necessary in the defense or settlement thereof. The Indemnifying
Parties shall not consent to a settlement of, or the entry of any judgment arising from, any such claim or legal proceeding, without the prior written consent of the Indemnified Parties, unless such settlement is solely for monetary damages and does
not involve the admission of wrongdoing by any of the Indemnified Parties, the Indemnifying Parties admit in writing their liability to hold the Indemnified Parties harmless from and against any and all Losses arising out of such settlement and
concurrently with such settlement the Indemnifying Parties pay into court the full amount of all Losses to be paid by the Indemnifying Parties in connection with such settlement, subject to the indemnity limitations hereunder. The Indemnified
Parties shall be entitled to participate in (but not control) the defense of any such action, with their own counsel and at their own expense and shall be entitled to any and all information or documentation relating thereto; provided, that,
if upon the advice of counsel, there shall exist a potential conflict of interest between the Indemnified Parties and the Indemnifying Parties or one or more defenses may be available to the Indemnified Parties that are not available to the
Indemnifying Parties, then, in each such case, the Indemnified Parties shall be entitled to participate in such defense with their own counsel at the expense of the Indemnifying Parties. If the Indemnifying Parties do not assume (or continue to
diligently and competently prosecute) the defense of any such claim or litigation resulting therefrom in accordance with the terms hereof the Indemnified Parties may defend against such claim or litigation in such manner as they may deem
appropriate, including, but not limited to, settling such claim or litigation, subject to the consent of the Indemnifying Parties (not to be unreasonably withheld, delayed or conditioned). The Indemnifying Parties shall be entitled to participate in
the defense of any action by the Indemnified Parties, which participation shall be limited to contributing information to the defense and being advised of its status. 
 SECTION 6.5 Manner of Indemnification. Within 30 calendar days after receipt of notice by the Indemnifying Parties of a claim by the Indemnified Parties, subject to the last sentence of

 SECTION 6.6 Intentionally Omitted.  

SECTION 6.7 Exclusive Remedy. The Indemnified Parties agree that indemnification under this Article VI shall be the
exclusive remedy against any Indemnifying Party for any breaches of any representations, warranties, covenants and agreements of the parties under this Agreement, the Ancillary Agreements and in any certificate delivered hereunder or thereunder,
except with respect to Fraud Claims or claims seeking equitable remedies. 
 SECTION 6.8 Accounts Receivable.

 (a) The Seller Indemnifying Parties shall reimburse the Acquiror Indemnified Parties the amount by which the sum of all
accounts receivable of the Companies reflected in the calculation of Closing Date Net Working Capital (the “Closing Date Receivables”) exceeds the sum of the amounts collected by the Companies in satisfaction of such Closing
Date Receivables by the later of the due date or 180 days after the Closing Date. Amounts paid “on account” and not designated by the payor to be paid in satisfaction of specific invoices or clearly identifiable to specific invoices shall
be presumed to have been paid in satisfaction of the payor’s oldest obligation to the Companies and shall be so applied on the books of the Companies. 
 (b) Upon payment to the Acquiror Indemnified Parties by the Seller Indemnifying Parties for any uncollected Closing Date Receivables pursuant to the terms hereof, Acquiror or its affiliates, as the case
may be, shall assign to the Seller Indemnifying Parties all of Acquiror’s right, title and interest in and to such Closing Date Receivables. 
 SECTION 6.9 Tax Matters. 
 (a) Tax Returns. The Seller Parties
shall prepare, or cause to be prepared, and shall timely file, or cause to be timely filed, all tax returns of the Companies, Alcomat, Allied Concrete and any of their Subsidiaries for all periods ending on or before the Closing Date. Acquiror shall
prepare, or cause to be prepared, and shall timely file, or cause to be timely filed, all tax returns of the Companies, Alcomat, Allied Concrete and any of their Subsidiaries for all periods ending after the Closing Date. 

(b) Sellers’ Obligations. The Seller Indemnifying Parties shall be responsible for and pay and shall indemnify and hold
harmless the Acquiror Indemnified Parties with respect to (i) any and all taxes imposed on the Companies, Alcomat, Allied Concrete and any of their Subsidiaries or for which the Companies, Alcomat, Allied Concrete and any of their Subsidiaries
are liable with respect to any periods ending on or before the Closing Date, including to the extent apportioned to such period pursuant to Section 6.9(d), and (ii) any costs or expenses with respect to taxes indemnified hereunder.
Any indemnity required to be made by the Seller Indemnifying Parties pursuant to this Section 6.9(b) shall be made within 30 days after the Sellers’ receipt of written notice from Acquiror. 

(c) Acquiror’s Obligations. Except as otherwise provided in Section 6.9(b), from and after the Closing Date,
Acquiror and the Companies shall be solely responsible for the payment or discharge of all taxes imposed on the Companies, Alcomat, Allied Concrete and any of their Subsidiaries for (i) all periods ending after the Closing Date and
(ii) any costs or expenses with respect to taxes indemnified hereunder. Acquiror shall indemnify, defend and hold the Seller Indemnified Parties harmless from any and all taxes that are Acquiror’s responsibility pursuant to the immediately
preceding sentence. Any indemnity payment required to be made by Acquiror pursuant to this Section 6.9(c) shall be made within 30 days after Acquiror’s receipt of written notice from the Sellers. 

  
 41 









 (d) Apportionment. For the sole purpose of appropriately apportioning any taxes
relating to a period that includes (but that would not end on) the Closing Date, Acquiror will, to the extent permitted by applicable Law, elect with the relevant taxing authority to treat for all purposes the Closing Date as the last day of a
taxable period of the Companies, Alcomat, Allied Concrete and any of their Subsidiaries. In the case where applicable Law does not permit the Companies, Alcomat, Allied Concrete and any of their Subsidiaries to treat the Closing Date as the last day
of a taxable period, then for purposes of this Agreement, the portion of such tax that is attributable to the Companies, Alcomat, Allied Concrete and any of their Subsidiaries for the part of such taxable period that ends on the Closing Date shall
be (i) in the case of a tax that is not transaction-based, the total amount of such tax for the full taxable period that includes the Closing Date multiplied by a fraction, the numerator of which is the number of days from the beginning of such
taxable period to and including the Closing Date and the denominator of which is the total number of days in such full taxable period, and (ii) in the case of transaction-based taxes, including any based on net income, the tax that would be due
with respect to such partial period, if such partial period were a full taxable period, apportioning income, gain, expenses, loss, depreciation, deductions and credits equitably based on an interim closing of the books. 

(e) Contests. For purposes of this Agreement, a “Contest” is any audit, court proceeding or other dispute
with respect to any tax matter that affects the Companies, Alcomat, Allied Concrete and any of their Subsidiaries. Unless Acquiror has previously received written notice from the Sellers of the existence of such Contest, Acquiror shall give written
notice to the Sellers of the existence of any Contest relating to a tax matter that is the responsibility of the Seller Indemnifying Parties under Section 6.9(b) within ten days from the receipt by Acquiror of any written notice of such
Contest, but no failure to give such notice shall relieve the Seller Indemnifying Parties of any liability hereunder, except to the extent that the Seller Indemnifying Parties are prejudiced by such failure to give timely notice. Unless the Sellers
have previously received written notice from Acquiror of the existence of such Contest, the Sellers shall give written notice to Acquiror of the existence of any Contest for which Acquiror has responsibility within ten days from the receipt by the
Sellers of any written notice of such Contest. Acquiror, on the one hand, and the Sellers, on the other hand, agree, in each case at no cost to the other party, to cooperate with the other and the other’s representatives in a prompt and timely
manner in connection with any Contest. Such cooperation shall include, but not be limited to, making available to the other party, during normal business hours, all books, records, returns, documents, files, other information (including, without
limitation working papers and schedules), officers or employees (without substantial interruption of employment) or other relevant information necessary or useful in connection with any Contest requiring any such books, records and files. The
Sellers shall, at their election, have the right to represent each of the Company’s interests in any Contest relating to a tax matter arising in a period ending on or before the Closing Date, to employ counsel of their choice at their expense
and to control the conduct of such Contest, including settlement or other disposition thereof; provided, however, that Acquiror shall have the right to consult with the Sellers regarding any such Contest that may affect either of the
Companies , Alcomat, Allied Concrete and any of their Subsidiaries or taxes relating to the BSI Properties for any periods ending after the Closing Date at Acquiror’s own expense and provided, further, that any settlement or other
disposition of any such Contest may only be with the consent of Acquiror, which consent will not be unreasonably withheld, delayed or conditioned. Acquiror shall have the right to control the conduct of any Contest with respect to any tax matter
arising in a period ending after the Closing Date. 
 (f) Controlling Provisions. In the event of any conflict between the
provisions of this Section 6.9 and any other provisions of this Article VI, this Section 6.9 shall be controlling with respect to any claim for indemnification for taxes. 

  
 42 









 (g) Transfer Taxes. All city and county documentary, stamp or other transfer taxes
relating to real property resulting from the transactions contemplated by this Agreement shall be borne and paid equally by the Seller Parties on the one hand and Acquiror on the other hand. 

(h) BSI Properties Tax Apportionment. Any real property taxes imposed with respect to the BSI Properties for the taxable period
that includes the Closing Date shall be borne by BSI and Acquiror (or its affiliates, including Alleyton), respectively, based on the proportionate number of days during such period that the BSI Properties were owned by BSI (which shall include the
Closing Date), on the one hand, and Acquiror (or its affiliates, including Alleyton), on the other hand. 
 (i) BSI Properties
Roll Back Tax Obligations. To the extent that real property taxes are owed with respect to the BSI Properties for any taxable period or portion thereof ending on or prior to the Closing Date solely as a result of Acquiror or its Affiliates
changing the use of the BSI Properties after the Closing Date such that the BSI Properties fail to qualify for the “open space” or “agricultural use” real property tax exemptions, such real property taxes shall be borne and paid
by Acquiror or its Affiliates.
