Parties harmless for, from, and against any and all Liabilities directly or indirectly arising from or relating to (i) any errors or omissions of any nature whatsoever contained in any legal proceedings or other official representation or
inducement made to the Issuer by or on behalf of the Company pertaining to the Bonds, and (ii) any Company fraud or misrepresentations or omissions contained in the proceedings of the Issuer relating to the issuance of the Bonds or pertaining
to the financial condition of the Company that, if known to the original purchaser of the Bonds could reasonably be considered a factor in such Person’s decision to purchase the Bonds; provided, however, nothing in this subsection shall be

“LITIGATION-The Issuer” as it relates to the Issuer.

applicable, provided that the Issuer Indemnified Party and Trustee Indemnified Party shall at all times also have the right to fully participate in the defense. If the Issuer Indemnified Party or Trustee Indemnified Party is advised by counsel that
there may be legal defenses available to either of them that are different from or in 

  
 15 

 
addition to those available to the Company or if the Company shall, after receiving notice of the indemnification obligation of the Company and within a period of time necessary to preserve any
and all defenses to any claim asserted, fails to assume the defense or to employ counsel for that purpose satisfactory to the Issuer Indemnified Party and Trustee Indemnified Party, as applicable, the Issuer Indemnified Party and Trustee Indemnified
Party, as applicable, shall have the right, but not the obligation, to undertake the defense of, and to compromise or settle the claim or other matter on behalf of, for the account of, and at the expense and risk of, the Company. 

(e) The Company shall be responsible for the reasonable counsel fees, costs, and expenses of the Issuer Indemnified Parties or the Trustee
Indemnified Parties in conducting its defense. 
 (f) Notwithstanding the foregoing, the Company shall not be considered an “Indemnified
Party” for purposes of this Section. 
 (g) The obligations of the Company under this Section shall survive the termination of this Loan
Agreement and the resignation or removal of the Trustee.

The Company shall not consolidate with or merge into any other Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person, and the Company shall not permit any Person to consolidate with or merge into
the Company or convey, transfer or lease its properties and assets substantially as an entirety to the Company, unless: 

(i) in case the Company shall consolidate with or merge into another Person or convey, transfer or lease its properties and
assets substantially as an entirety to any Person, the Person formed by such consolidation or into which the Company is merged or the Person which acquires by conveyance or transfer, or which leases, the properties and assets of the Company
substantially as an entirety shall (1) be qualified to do business in the State, (2) be organized and validly existing under the laws of the United States of America, any State thereof or the District of Columbia and (3) expressly
assume, by amendment hereto, executed and delivered to the Issuer, the due and punctual payment of the principal of and interest on the Note and the performance or observance of every covenant of this Loan Agreement on the part of the Company to be
performed or observed; and 
 (ii) immediately after giving effect to such transaction, no Event of Default, and no event
which, after notice or lapse of time or both, would become an Event of Default, shall have happened and be continuing. 
 Upon any
consolidation of the Company with, or merger of the Company into, any other Person or any conveyance, transfer or lease of the properties and assets of the Company substantially as an entirety in accordance with this Section 7.3, the successor
Person formed by such consolidation or into which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Loan Agreement
with the same effect as if such successor Person had been named as the Company herein, and thereafter, except in the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under this Loan Agreement and under the
Note.

 Section 7.5. Tax Covenants. 

(a) The Company represents and covenants that it will comply with the Tax Regulatory Agreement and will not take any action or omit to take any
action, or permit to be taken or omitted, which action or omission will adversely affect the exclusion from gross income of the interest on the Tax-Exempt Bonds for federal income tax purposes, and in the
event of such action or omission, it will, promptly upon having such brought to its attention, take such reasonable actions based upon an Opinion of Bond Counsel, and in all cases at the sole expense of the Company, as may rescind or otherwise
negate such action or omission. The Company further covenants and agrees that it will not, directly or indirectly, use or permit the use of any funds provided by the Issuer hereunder or any other funds of the Company, in a manner which would, or
enter into, or allow any “related person” (as defined in Code Section 147(a)(2)), to enter into any arrangement, formal or informal, for the purchase of the Bonds that would, or take or omit to take any action that would, to the
knowledge of the Company, cause the that would cause the Tax-Exempt Bonds to be or become “arbitrage bonds” within the meaning of Section 148(a) of the Code (or their statutory predecessor) or
“federally guaranteed” within the meaning of Code Section 149(b) and the applicable regulations promulgated from time to time thereunder. The Company further covenants to comply with the covenants and procedures set forth in
Section 6.11 of the Indenture and the Tax Regulatory Agreement and to deliver the Rebate Amount Certificate to the Trustee when required and to deposit in the Rebate Fund such amount as may be required and the Issuer, at the request and
direction of the Company, hereby selects October 15 as the end of the “bond year” with respect to the Tax-Exempt Bonds. The Company further covenants and agrees it will not fail to meet any
other applicable requirement of Sections 103 and 141through 150 of the Code (or their statutory predecessor) or cause the interest on the Tax-Exempt Bonds to lose their exclusion from Arizona taxable income
under present Arizona law. To that end, the Company will comply with all requirements of Sections 103 and 141 through 150 of the Code (or their statutory predecessor) to the extent applicable to the Tax-Exempt
Bonds. In the event that at any time the Company is of the opinion that, for purposes of this Section 7.5, it is necessary to restrict or limit the yield on the investment of any moneys held by the Trustee or otherwise, the Company shall so
instruct the Trustee in writing. 
 (b) The Issuer and the Company hereby covenant and agree that they shall not enter into any arrangement,
formal or informal, pursuant to which the Company (or any “related party,” as defined in Section 1.150-1(b) of the Treasury Regulations) shall purchase the
Tax-Exempt Bonds. This covenant shall not prevent the Company from purchasing Bonds in the open market for the purpose of tendering them to the Trustee for purchase and retirement. 

(c) The Company covenants, represents and warrants that it comply with the procedures set forth in the Tax Regulatory Agreement implementing
the covenants in this Section 7.5 to the extent necessary under the Code to maintain the exclusion from gross income of interest on the Tax-Exempt Bonds for federal income tax purposes or to avoid the
application of any penalties under the Code, subject to any applicable statute of limitations. 
 Section 7.6.
Reference to Bonds Ineffective After Bonds Paid. Upon Payment of the Bonds and upon payment of all obligations under this Loan Agreement, all references in this Loan Agreement to the Bonds and the Trustee shall be ineffective, and
neither the Trustee nor the holders of any of the Bonds shall thereafter have any rights hereunder except as provided in Section 7.2 hereof and except with regard to payments of any documented, out of pocket reasonable fees and expenses of the
Issuer by the Company in accordance with this Loan Agreement.

Bankruptcy. 
 (a) The Company shall promptly notify the Trustee and the Issuer in writing upon the occurrence of any Event of Default of
which the Company has knowledge. 
 (b) The Company shall notify the Trustee and the Issuer in writing as soon as it has knowledge of any
material actions, suits or proceedings at law, in equity or before or by any governmental authority, pending or, to its knowledge, threatened in writing, materially and adversely affecting the ability of the Company to perform its obligations
hereunder, or materially and adversely impacting the validity or enforceability of the Note or this Loan Agreement. 
 (c) The Company shall
notify the Trustee and the Issuer (i) in writing within two days if a petition in bankruptcy is filed by the Company or (ii) within 30 days if a petition in bankruptcy is filed against the Company, in either case as debtor under the
federal bankruptcy laws or other proceedings are commenced with respect to the Company under other applicable bankruptcy, reorganization or insolvency laws, as now or hereafter constituted. 

Section 7.8. Compliance with Indenture. The Issuer will perform all of its agreements in the
Indenture, and, except for the assignment of this Loan Agreement (excluding the Issuer’s Unassigned Rights) pursuant to the Indenture, will not convey its interest in this Loan Agreement. The Company covenants and agrees to do all things within
its power in order to comply with and to enable the Issuer to comply with all requirements and to fulfill all covenants of the Indenture insofar as the same relate to or are applicable to the Company (including but not limited to payment of the
documented, out of pocket, reasonable fees and expenses, including reasonable legal fees and expenses, of the Trustee). The Issuer agrees that it will not amend or supplement the Indenture so as to increase the burdens or liabilities of the Company
or affect the rights of the Company without the prior written consent of the Company. The Company hereby agrees that it has received an executed copy of the Indenture and that it is familiar with its provisions, and the Company hereby approves the
terms and provisions of the Indenture and the Series 2022 Bonds. 
 Section 7.9. Further Assurances. 

(a) The Company agrees to provide the notices and certificates to the Issuer and the Trustee, as appropriate, in accordance with the provisions
relating to redemption of the Bonds under certain circumstances as set forth in Article III of the Indenture. 
 (b) The Company agrees to
provide all notices and certificates to the Issuer and the Trustee as appropriate, that are required under the Indenture in accordance with the terms thereof.

(b) Failure of the Company to observe and perform any of its payments (other than the payments specified in clause (a) above), covenants,
conditions or agreements under this Loan Agreement for a period of 30 days after receipt of notice from the Issuer or the Trustee to the Company, specifying such failure and requesting that it be remedied, provided that, if such failure is not
susceptible of cure within 30 days and the Company has commenced and is diligently pursuing a cure, such 30 day period shall be extended for so long as is reasonably necessary to cure such failure; or 

  
 18 

 (c) (i) Commencement by the Company of a voluntary case under the federal bankruptcy
laws, as now or hereafter constituted, or any other applicable federal or state bankruptcy, insolvency or other similar law, (ii) consent by the Company to the appointment of a receiver, liquidator, assignee, trustee, custodian, sequestrator or
other similar official for the Company or any substantial part of its property, or to the taking possession by any such official of any substantial part of the property of the Company, (iii) making by the Company of any assignment for the
benefit of creditors, or (iv) taking of any other action by the Company, in furtherance of any of the foregoing; or 
 (d) The

applicable federal or state bankruptcy, insolvency or other similar law, (ii) appointment of a receiver, liquidator, assignee, trustee, custodian, sequestrator or similar official for the Company, or any substantial part of its property, or

connection with the issuance or sale of the Series 2022 Bonds was false or misleading in any material respect at the time it was made or delivered, and the adverse effect of any such warranty or representation is not cured within 30 days of notice
thereof from the Issuer or the Trustee to the Company; or 
 (g) An Event of Default has occurred and is continuing under Sections 1001(a) or
(b) of the Indenture, which has not been cured or waived by the holders of the Series 2022 Bonds thereunder in accordance with the terms of the Indenture. 

The provisions of subsection (b) and (g) above are subject to the limitation that if by reason of force majeure the Company is unable in
whole or in part to observe and perform any of its covenants, conditions or agreements contained hereunder, other than its payment obligations and other obligations contained in Sections 4.1, 5.3, 7.2, 7.3, 7.5 or 9.1 hereof, the Company shall not
be deemed in default during the continuance of such inability. The term “force majeure” as used herein shall include without limitation acts of God; strikes, lockouts or other industrial disturbances; acts of public enemies; orders of any
kind of the government of the United States of America or the State or any political subdivision thereof or any of their departments, agencies or officials, or any civil or military authority; insurrections; riots; epidemics and pandemics, including

shall not be required to make settlement of strikes, lockouts and other industrial disturbances by agreeing to the demands of any opposing party when such course is in the judgment of the Company unfavorable to the Company. 

Notwithstanding anything herein to the contrary, a Determination of Taxability shall not result in or constitute an Event of Default if
Section 9.1 is complied with. 

  
 19 

 Section 8.2. Remedies. Upon the occurrence of an
Event of Default, and at any time thereafter during the continuation of such Event of Default, the Issuer (in the case of the Issuer’s Unassigned Rights in the event of a failure of the Trustee to act under this subsection) and the Trustee, as
assignee of the Issuer, may (but shall not be obligated to) exercise any right or remedy available to it in law or equity to enforce all other rights under this Loan Agreement and the Trustee may (but shall not be obligated to) take one or more of
the following remedial steps; and in the event that as a result of such Event of Default, the Trustee declares the principal amount of all Series 2022 Bonds then outstanding, together with any accrued and unpaid interest thereon, to be immediately
due and payable under Article X of the Indenture, the Trustee shall take the remedial step set forth in Section 8.2(a) hereof: 
 (a)
declare the principal of, and all interest then accrued on, the loan to be forthwith due and payable, whereupon the same shall forthwith become due and payable without presentment, demand, protest, notice of default, notice of acceleration, or of
intention to accelerate or other notice of any kind (other than notice of such declaration) all of which the Company hereby expressly waive, anything contained in the Loan Agreement to the contrary notwithstanding; provided that if any Event of
Default specified in Sections 8.1(c), 8.1(d) or 8.1(e) shall occur, the principal of, and all interest on, the loan shall automatically and immediately thereupon become due and payable concurrently therewith, without any further action by the Issuer
or Trustee, or any of them, and without presentment, demand, protest, notice of default, notice of acceleration, or of intention to accelerate or other notice of any kind, all of which the Company expressly waives; or 

(b) take any action at law or in equity to collect the payments then due and thereafter to become due hereunder or under the Note or to enforce
performance and observance of any obligation, agreement or covenant of the Company under this Loan Agreement; or 
 (c) exercise all rights
and remedies provided for in the Indenture; or 
 (d) after prior written notice to the Company, unless the giving of such notice would
prejudice the Trustee (as determined in its sole discretion), perform for the account of the Company any covenant in the performance of which the Company is in default or make any payment for which the Company is in default; provided that the
Company shall pay to the Trustee upon demand any amount paid by the Trustee in the performance of such covenant; and provided that any amounts which shall have been paid by reason of failure of the Company to comply with any covenant or provision of
this Loan Agreement, including reasonable legal counsel fees, incurred in connection with prosecution or defense of any proceedings instituted by reason of default of the Company, shall bear interest at U.S. Bank National Association’s
announced prime rate plus two (2%) percent or the highest rate permitted by law, whichever is less, from the date of payment by the Trustee until paid by the Company; or 

(e) to pay or perform any obligation on behalf of the Company in connection with the Project. 

If any party shall have proceeded to enforce this Loan Agreement by suit or action in equity or in law and such proceedings shall have been
discontinued or abandoned for any reason or shall have been determined adversely to such party, then the Company, the Issuer and the Trustee shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and
powers of the Company, the Issuer and the Trustee shall continue as though no such proceedings had taken place. 

  
 20 

 Section 8.3. Additional Remedies. In addition to the
above rights and remedies, if an Event of Default occurs, the Issuer and the Trustee shall have the right (but not the obligation) and remedy, without posting bond or other security, to have the provisions of this Loan Agreement specifically
enforced by any court having equity jurisdiction, it being acknowledged and agreed that any such Event of Default will cause irreparable injury to the Issuer or the Trustee and that money damages will not provide an adequate remedy therefor. 

Section 8.4. Right of Trustee to Exercise Remedies. The Company acknowledges that the Trustee, as the
assignee of the Issuer’s rights hereunder, has the right (but not the obligation) to exercise all rights and remedies set forth herein or otherwise available to the Issuer at law or in equity. 

Section 8.5. Waiver of Errors and Exemptions. The Company hereby waives and releases all errors,
defects and imperfections whatsoever of a procedural nature in the entering of any judgment or any process or proceedings arising out of this Loan Agreement or the Note and the benefit of any law which now or hereafter might authorize the stay of
any execution to be issued on any judgment recovered hereunder or the exemption of any property from levy or sale thereunder. 

Section 8.6. No Remedy Exclusive. No right or remedy herein conferred or reserved is intended to be
exclusive of any other available rights and remedy or remedies, but each and every such right and remedy shall be cumulative and shall be in addition to every other right and remedy given under this Loan Agreement or now or hereafter existing at law
or in equity or by statute. No delay or omission to exercise any right, remedy, privilege or power accruing upon any default shall impair any such right, remedy, privilege or power or shall be construed to be a waiver thereof, but any such right,
remedy, privilege or power may be exercised from time to time and as often as may be deemed expedient. No notice, other than such notice as may be required precedent to the exercise of any right or remedy hereunder or at law, in equity or pursuant
to statute, shall be required in connection with the exercise of any right or remedy hereunder. 
 Section 8.7.
Agreement to Pay Attorney’s Fees and Expenses. If the Company should default under any of the provisions of this Loan Agreement and either the Issuer or the Trustee shall require and employ attorneys or incur
other expenses for the collection of payments due or to become due or for the enforcement or performance or observance of any obligation or agreement on the part of the Company herein contained, the Company agrees that it will on demand therefor pay
to the Issuer or the Trustee the actual and documented fees of such attorneys reasonably incurred and such other expenses so incurred, including any sums due the Trustee in its capacity as agent for the Issuer. 

Section 8.8. No Waiver Implied. Any failure by the Issuer or the Trustee to insist upon the strict
performance by the Company of any of the terms, covenants, agreements, conditions and provisions hereof shall not be deemed to be a waiver of any of the terms, covenants, agreements, conditions or provisions hereof, and notwithstanding any such
failure, the Issuer and the Trustee shall have the right thereafter to insist upon the strict performance by the Company of any and all of the terms, covenants, agreements, conditions and provisions of this Loan Agreement. Neither the Company nor
any other person now or hereafter obligated for the payment of the whole or any part of the sums now or hereafter secured hereunder shall be relieved of such obligation by reason of the failure of the Issuer or the Trustee to comply with any request
of the Company or of any other person so obligated to take action to enforce any of the provisions of this Loan Agreement or the extension of the time of payment hereunder or modifying the terms hereof and in the latter event, the Company and all
such other persons shall continue to be liable to make such payments according to the terms of any such agreement of extension or modification unless expressly released and discharged in writing by the Issuer and the Trustee. No waiver of any breach
of the Company of any of its obligations, agreements or covenants hereunder shall be a waiver of any subsequent breach or of any other obligation, agreement or covenant, nor shall any forbearance to seek a remedy for any breach by the Company be a
waiver of any rights and remedies with respect to any subsequent breach. 

  
 21 

 Section 8.9. Waiver of Trial by Jury. Each party
hereto waives trial by jury in any litigation in any court with respect to, in connection with, or arising out of, this Loan Agreement, the Indenture, the Bonds, the Note, or any instrument delivered pursuant to any of them or the validity,
protection, interpretation, collection or enforcement thereof.

the Company shall reimburse the Issuer for its reasonable expenses, including attorneys’ fees, incurred in complying with such request. Following the occurrence of any repurchase or redemption of Bonds under the Indenture (regardless of whether
such repurchase or redemption is due to a Change of Control Offer, optional redemption or repurchase, mandatory redemption or repurchase, or otherwise), the Loan Agreement and the Note will be automatically reduced hereunder in an amount equal

FACILITY DESCRIPTION 
 The
Facility consists of a steel micro mill for the manufacturing of rebar and merchant bar exclusively from recycled ferrous materials and will be situated on an approximately 83.6 acre site located at 11444 East Germann Road, Mesa, Maricopa County,
Arizona 85212. The Facility will be the Company’s third micro mill and will be the first in the world to produce merchant bar quality (“MBQ”) products through a continuous production process. The Facility will employ the latest
technology in EAF power supply systems which will allow the Company to directly connect the EAF and the ladle furnace to renewable energy sources such as solar and wind. The Facility will replace the rebar capacity at the Rancho Cucamonga,
California facility, which ceased production in December 2020 and the large parcel of land underlying the aforementioned facility and adjacent rebar fabrication facility was sold on December 28, 2021, The Company expects the production for the new
mill to be approximately 500,000 tons, including up to approximately 150,000 tons MBQ. The Company began initial construction of the Facility in September 2021 and operations are expected to begin in 2023. The Company expects the net project
investment to be between $250.0 million and $300.0 million. 
 The Company believes the Facility will help optimize the
Company’s asset portfolio by replacing an outdated high-cost capacity mill with a low-cost, more efficient micro mill. The Facility will also allow the Company to more efficiently meet U.S. west coast
demand for steel products while using local, low-cost scrap supply. The Company views the Facility as environmentally friendly because it is replacing an old melt shop with newer, cleaner technology that is
expected to have a more favorable emissions and energy usage profile while providing the ability to direct-connect to renewable energy sources. 

CMC Steel Fabricators, Inc., a wholly-owned subsidiary of Commercial Metals Company, will construct, own and operate the facility on land
owned by Commercial Metals Company.
