 Section 2.3 

Section 2.3.1 [INTENTIONALLY DELETED] 

Section 2.3.2 Increased Costs; Capital Adequacy; Funding Exceptions. If a Related Lender (as defined below) determines at any time
that its Return (as defined below) has been reduced as a result of any Rule Change, such Lender may so notify the Borrower and require the Borrower, beginning fifteen (15) days after such notice, to pay it the amount necessary to restore its
Return to what it would have been had there been no Rule Change. For purposes of this Section 2.3: 
 (a) “Capital
Adequacy Rule” means any law, rule, regulation, guideline, directive, requirement or request regarding capital adequacy, or the interpretation or administration thereof by any governmental or regulatory authority, central bank or comparable
agency, whether or not having the force of law, that applies to any Related Lender (as defined below), including rules requiring financial institutions to maintain total capital in amounts based upon percentages of outstanding loans, binding loan
commitments and letters of credit. Notwithstanding anything herein to the contrary (x) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, guidelines or directives thereunder or issued in connection therewith,
and (y) all requests, rules, guidelines or directives promulgated by the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the United States or foreign regulatory
authorities, in each case pursuant to Basel III, shall in each case be deemed to be a “Capital Adequacy Rule”, regardless of the date enacted, adopted or issued. 

(b) “L/C Rule” means any law, rule, regulation, guideline, directive, requirement or request regarding letters of
credit, or the interpretation or administration thereof by any governmental or regulatory authority, central bank

deposits or similar requirements against assets of, deposits with or for the account of, or credit extended by any Related Lender, on letters of credit. 

(c) “Related Lender” includes (but is not limited to) the Lender, any parent of the Lender, any assignee of any
interest of the Lender hereunder and any participant in the Credit Facility. 
 (d) “Return,” for any period, means
the percentage determined by dividing (i) the sum of interest and ongoing fees earned by the Related Lender under this Agreement during such period, by (ii) the average capital such Lender is required to maintain during such period as a
result of its being a party to this Agreement, as determined by such Lender based upon its total capital requirements and a reasonable attribution formula that takes account of the Capital Adequacy Rules and L/C Rules then in effect, costs of
issuing or maintaining any Advance or Letter of Credit and amounts received or receivable under this Agreement or the Notes with respect to any Advance or Letter of Credit. Return may be calculated for each calendar quarter and for the shorter
period between the end of a calendar quarter and the date of termination in whole of this Agreement. 
 (e) “Rule
Change” means any change in any Capital Adequacy Rule or L/C Rule occurring after the date of this Agreement, or any change in the interpretation or administration thereof by any governmental or regulatory authority, but the term does not
include any changes that at the Funding Date are scheduled to take place under the existing Capital Adequacy Rules or L/C Rules or any increases in the capital that the Lender is required to maintain to the extent that the increases are required due
to a regulatory authority’s assessment of such Related Lender’s financial condition. 
 The initial notice sent by the Related Lender shall be
sent as promptly as practicable after such Lender learns that its Return has been reduced, shall include a demand for payment of the amount necessary to restore such Lender’s Return for the quarter in which the notice is sent, and shall state
in reasonable detail the cause for the reduction in its Return and its calculation of the amount of such reduction. Thereafter, such Related Lender may send a new notice during each calendar quarter setting forth the calculation of the reduced
Return for that quarter and including a demand for payment of the amount necessary to restore its Return for that quarter. The Related Lender’s calculation in any such notice shall be conclusive and binding absent demonstrable error. 

Section 2.4 Letters of Credit. 

(a) The Lender agrees, on the terms and subject to the conditions herein set forth, to cause an Issuer to issue, from the
Funding Date to the Termination Date, one or more irrevocable standby or documentary letters of credit (each, a “Letter of Credit”) for the Borrower’s account by guaranteeing payment of the Borrower’s obligations or being a
co-applicant. The Lender shall have no obligation to cause an Issuer to issue any Letter of Credit if the face amount of the Letter of Credit to be issued would exceed the lesser of (i) $5,000,000.00 less the Letter of Credit Amount, or
(ii) Availability. 

  
 17 

 Each Letter of Credit, if any, shall be issued pursuant to a separate L/C Application entered
into between the Borrower and the Lender for the benefit of the Issuer, completed in a manner satisfactory to the Lender and the Issuer. The terms and conditions set forth in each such L/C Application shall supplement the terms and conditions
hereof, but if the terms of any such L/C Application and the terms of this Agreement are inconsistent, the terms hereof shall control. 

(b) No Letter of Credit shall be issued with an expiry date later than the Termination Date in effect as of the date of
issuance. 
 (c) Any request to cause an Issuer to issue a Letter of Credit shall be deemed to be a representation by the
Borrower that the conditions set forth in Section 4.2 have been satisfied as of the date of the request. 
 Section 2.5 Special
Account. If the Credit Facility is terminated for any reason while any Letter of Credit is outstanding, the Borrower shall thereupon pay the Lender in immediately available funds for deposit in the Special Account an amount equal to the L/C
Amount. The Special Account shall be an interest bearing account maintained for the Lender by any financial institution acceptable to the Lender. Any interest earned on amounts deposited in the Special Account shall be credited to the Special
Account. The Lender may apply amounts on deposit in the Special Account at any time or from time to time to the Obligations in the Lender’s sole discretion. The Borrower may not withdraw any amounts on deposit in the Special Account as long as
the Lender maintains a security interest therein. The Lender agrees to transfer any balance in the Special Account to the Borrower when the Lender is required to release its security interest in the Special Account under applicable law. 

Section 2.6 Payment of Amounts Drawn Under Letters of Credit; Obligation of Reimbursement. The Borrower acknowledges that the
Lender, as co-applicant, will be liable to the Issuer for reimbursement of any and all draws under Letters of Credit and for all other amounts required to be paid under the applicable L/C Application. Accordingly, the Borrower shall pay to the
Lender any and all amounts required to be paid under the applicable L/C Application, when and as required to be paid thereby, and the amounts designated below, when and as designated: 

(a) The Borrower shall pay to the Lender on the day a draft is honored under any Letter of Credit a sum equal to all amounts
drawn under such Letter of Credit plus any and all reasonable charges and expenses that the Issuer or the Lender may pay or incur relative to such draw and the applicable L/C Application, plus interest on all such amounts, charges and expenses as
set forth below (the Borrower’s obligation to pay all such amounts is herein referred to as the “Obligation of Reimbursement”). 

(b) Whenever a draft is submitted under a Letter of Credit, the Borrower authorizes the Lender to make a Revolving Advance in
the amount of the Obligation of Reimbursement and to apply the proceeds of such Revolving Advance thereto. Such Revolving Advance shall be repayable in accordance with and be treated in all other respects as a Revolving Advance hereunder. 

  
 18 

 (c) If a draft is submitted under a Letter of Credit when the Borrower is unable,
because a Default Period exists or for any other reason, to obtain a Revolving Advance to pay the Obligation of Reimbursement, the Borrower shall pay to the Lender on demand and in immediately available funds, the amount of the Obligation of
Reimbursement together with interest, accrued from the date of the draft until payment in full at the Default Rate. Notwithstanding the Borrower’s inability to obtain a Revolving Advance for any reason, the Lender is irrevocably authorized, in
its sole discretion, to make a Revolving Advance in an amount sufficient to discharge the Obligation of Reimbursement and all accrued but unpaid interest thereon. 

(d) The Borrower’s obligation to pay any Revolving Advance made under this Section 2.6 shall be evidenced by the
Revolving Note and shall bear interest as provided in Section 2.8. 
 Section 2.7 Obligations Absolute. The Borrower’s
obligations arising under Section 2.6 shall be absolute, unconditional and irrevocable, and shall be paid strictly in accordance with the terms of Section 2.7, under all circumstances whatsoever, including (without limitation) the
following circumstances: 
 (a) any lack of validity or enforceability of any Letter of Credit or any other agreement or
instrument relating to any Letter of Credit (collectively the “Related Documents”); 
 (b) any amendment or waiver
of or any consent to departure from all or any of the Related Documents; 
 (c) the existence of any claim, setoff, defense
or other right which the Borrower may have at any time, against any beneficiary or any transferee of any Letter of Credit (or any persons or entities for whom any such beneficiary or any such transferee may be acting), or other person or entity,
whether in connection with this Agreement, the transactions contemplated herein or in the Related Documents or any unrelated transactions; 

(d) any statement or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; 
 (e) payment by
or on behalf of the Issuer under any Letter of Credit against presentation of a draft or certificate which does not strictly comply with the terms of such Letter of Credit; or 

(f) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing. 

Section 2.8 Interest; Default Interest; Participations; Usury. 

(a) Note. Except as set forth in subsections (b) and (d), (i) the outstanding principal balance
of the Revolving Note and each Revolving Advance shall bear interest at the Floating Rate, and (ii) the outstanding principal balance of the Real Estate Term Note and the Real Estate Term Advance shall bear interest at the Term Floating Rate.

  
 19 

 (b) Default Interest Rate. Upon notice to the Borrower from
the Lender from time to time, the principal of the Advances outstanding from time to time shall bear interest at the Default Rate, effective as of the first day of the fiscal month during which any Default Period begins through the last day of such
Default Period. The Lender’s election to charge the Default Rate shall be in its sole discretion and shall not be a waiver of any of its other rights and remedies. The Lender’s election to charge interest at the Default Rate for less than
the entire period during which the Default Rate may be charged shall not be a waiver of its right to later charge the Default Rate for the entire such period. 

(c) Participations. If any Person shall acquire a participation in the Advances or the Obligation of
Reimbursement, the Borrower shall be obligated to the Lender to pay the full amount of all interest calculated under this Section 2.8(c), along with all other fees, charges and other amounts due under this Agreement, regardless if such Person
elects to accept interest with respect to its participation at a lower rate than that calculated under this Section 2.8, or otherwise elects to accept less than its pro rata share of such fees, charges and other amounts due under this
Agreement. 
 (d) Usury. In any event no rate change shall be put into effect which would result in a
rate greater than the highest rate permitted by law. Notwithstanding anything to the contrary contained in any Loan Document, all agreements which either now are or which shall become agreements between the Borrower and the Lender are hereby limited
so that in no contingency or event whatsoever shall the total liability for payments in the nature of interest, additional interest, Default Interest, fees payable hereunder, and other charges exceed the applicable limits imposed by any applicable
usury laws. If any payments in the nature of interest, additional interest, Default Interest, fees payable hereunder, and other charges made under any Loan Document are held to be in excess of the limits imposed by any applicable usury laws, it will
be deemed a mutual mistake and any such amount held to be in excess shall be considered payment of principal hereunder, and the indebtedness evidenced hereby shall be reduced by such amount (or if there is no existing indebtedness, refunded to the
Borrower) so that the total liability for payments in the nature of interest, additional interest and other charges shall not exceed the applicable limits imposed by any applicable usury laws, in compliance with the desires of the Borrower and the
Lender. All amounts constituting interest will be spread throughout the full term of the indebtedness evidenced hereby in determining whether interest exceeds lawful amounts. The Borrower agrees that the interest rate contracted for herein includes
the interest rate set forth in this Section 2.8 plus any other charges or fees set forth herein and costs and expenses incident to this transaction paid by the Borrower to the extent that they are deemed interest under applicable law. This
provision shall never be superseded or waived and shall control every other provision of the Loan Documents and all agreements between the Borrower and the Lender, or their successors and assigns. 

  
 20 

 Section 2.9 Fees. 

(a) Amended and Restated Fee. The Borrower shall pay to the Lender, on the date hereof, a fully earned,
non-refundable, amended, restated and origination fee in the amount of $37,500.00.

shall pay the Lender, on demand, reasonable audit fees in connection with any audits or inspections conducted by or on behalf of the Lender of any Collateral or the Borrower’s operations or business at the rates established from time to time by
the Lender as its audit fees (which fees are currently $125.00 per hour per auditor), together with all actual out-of-pocket costs and expenses reasonably incurred in conducting any such audit or inspection. 

(c) Letter of Credit Fees. The Borrower shall pay to the Lender a fee with respect to each Letter of
Credit, if any, accruing on a daily basis and computed at the annual rate of three percent (3.00%), of the aggregate amount that may then be drawn under it assuming compliance with all conditions for drawing (the “Aggregate Face Amount”),
from and including the date of issuance of such Letter of Credit until such date as such Letter of Credit shall terminate by its terms or be returned to the Lender, due and payable monthly in arrears on the first day of each month and on the
Termination Date; provided, however, that during Default Periods, in the Lender’s sole discretion and without waiving any of its other rights and remedies, such fee shall increase to six percent (6.0%) of the Aggregate Face
Amount. The foregoing fee shall be in addition to any and all fees, commissions and charges of the Issuer with respect to or in connection with such Letter of Credit. 

(d) Letter of Credit Administrative Fees. The Borrower shall pay to the Lender, on written demand, the
administrative fees charged by the Issuer in connection with the honoring of drafts under any Letter of Credit, amendments thereto, transfers thereof and all other activity with respect to the Letters of Credit at the then-current rates published by
the Issuer for such services rendered on behalf of customers of the Issuer generally. 
 (e) Termination and Line
Reduction Fees. If (i) the Lender terminates the Credit Facility as a result of the occurrence of an Event of Default, or if (ii) the Borrower terminates the Credit Facility or reduces the Maximum Line on a date prior to the
Maturity Date, then the Borrower shall pay the Lender as liquidated damages and not as a penalty a termination fee in an amount equal to a percentage of the Maximum Line (or the reduction of the Maximum Line, as the case may be) calculated as
follows: (A) three percent (3.0%) if the termination or reduction occurs on or before June 30, 2015; (B) two percent (2.0%) if the termination or reduction occurs after June 30, 2015 but on or before June 30, 2017;
and (C) one percent (1.0%) if the termination or reduction occurs after June 30, 2017. 
 (f) Waiver of
Termination Fees. The Borrower will not be required to pay the termination fees otherwise due under subsection (e) if such termination is made because of refinancing by an affiliate of the Lender. 

  
 21 

 (g) Unused Line Fee. For the purposes of this Section 2.9(g),
“Unused Amount” means the Maximum Line reduced by outstanding Revolving Advances. The Borrower agrees to pay to the Lender an unused line fee at the rate of one-half of one percent (0.50 %) per annum on the average daily Unused Amount from
the date of this Agreement to and including the Termination Date, due and payable monthly in arrears on the first Banking Day of the month and on the Termination Date. 

(h) Other Fees. The Lender may from time to time charge additional fees: (i) for Revolving Advances made and
Letters of Credit issued in excess of Availability (which over-advance fees are currently $500 per day when there is no Default Period and $1,000 per day when a Default Period exists, and may be charged for each day that the over-advance exists);
(ii) in lieu of imposing interest at the Default Rate during a Default Period; (iii) for wire transfer fees; and (iv) for other fees which are customarily charged by the Lender and are reasonable in amount. Fees charged pursuant to clause
(ii) above will not exceed the Default Rate which could be charged because of the Default or Event of Default permitting the fees. Neither the charging nor the payment of overadvance fees shall be deemed to excuse or waive the Borrower’s
obligation to comply with provisions of Section 2.13 or to waive any Default of the Borrower arising from the Borrower’s failure to comply with the provisions of Section 2.13. The Borrower’s request for a Revolving Advance in
excess of Availability, the issuance of a Letter of Credit in excess of Availability or the Borrower’s failure to comply with the provisions of Section 2.13 shall constitute the Borrower’s agreement to pay the over-advance fees
described in such notice. 
 (i) Real Estate Term Advance Closing Fee. The Borrower shall pay to the Lender, on
the date hereof, a fully earned, non-refundable Real Estate Term Advance origination fee in the amount of $100,000.00 
 (j)
Real Estate Term Advance Prepayment Fee. If the Real Estate Term Advance is prepaid in whole or in part prior to the Real Estate Facility Maturity Date for any reason, then on the date of any such prepayment, the Borrower shall pay to
the Lender as liquidated damages and not as a penalty a prepayment fee in an amount equal to (i) three percent (3.0%) of the amount prepaid, if prepayment occurs on or before [insert date that is first anniversary of closing]; and
(ii) two percent (2.0%) of the amount prepaid, if prepayment occurs after [insert date that is first anniversary of closing] but on or before [insert date that is second anniversary of closing].

 22 

 (p) Facility Fee. The Borrower agrees to pay an annual facility fee
in the amount of $100,000.00 on each February 1st. All such amounts shall be paid in full when due regardless of whether they become due in any partial year. 

(q) [Intentionally Deleted] 

Section 2.10 Time for Interest Payments; Payment on Non-Banking Days; Computation of Interest and Fees. 

(a) Time For Interest Payments. Accrued and unpaid interest accruing on Advances shall be due and payable on the
first day of each month and on the Termination Date (each an “Interest Payment Date”), or if any such day is not a Banking Day, on the next succeeding Banking Day. Interest will accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from the date of advance to the Interest Payment Date. If an Interest Payment Date is not a Banking Day, payment shall be made on the next succeeding Banking Day. 

(b) Payment on Non-Banking Days. Whenever any payment to be made hereunder shall be stated to be due on a day
which is not a Banking Day, such payment may be made on the next succeeding Banking Day, and such extension of time shall in such case be included in the computation of interest on the Advances or the fees hereunder, as the case may be. 

(c) Computation of Interest and Fees. Interest accruing on the outstanding principal balance of the Advances and
fees hereunder outstanding from time to time shall be computed on the basis of actual number of days elapsed in a year of 360 days. 

Section 2.11 Lockbox; Collateral Account; Application of Payments. 

(a) Lockbox and Collateral Account. 

(i) If an Event of Default occurs and the Lender requests that they do so, or regardless of whether or not an Event of Default
or Default Period exists, if the sum of Availability plus Cash and Cash Equivalents on deposit with Lender at any time is less than $7,500,000.00 for five consecutive business days, then in either event (A) the Borrower shall instruct all
account debtors to pay all its Accounts directly to a lockbox (the “Lockbox”) established with Wells Fargo Bank or another bank selected by the Lender and reasonably satisfactory to the Borrower and (B) the Borrower shall execute and
deliver to the Lender a lockbox agreement in form and substance satisfactory to the Lender in its sole and absolute judgment. If, notwithstanding such instructions, the Borrower receives any payments on their Accounts, the Borrower shall deposit
such payments into a collateral account maintained with Lender (the “Collateral Account”). The Borrower shall also deposit all other cash proceeds of Collateral directly to the Collateral Account if received at a time that the Borrower is
required to deposit payments on their Accounts into the Collateral 

  
 23 

 
Account. In addition, and regardless of whether or not an Event of Default or Default Period exists, if the sum of Availability plus Cash and Cash Equivalents on deposit with Lender at any time
is less than $7,500,000.00 for five consecutive business days, then in such event, all proceeds of Collateral received by Borrower shall be immediately deposited in the Collateral Account. In all such events, until so deposited, the Borrower shall
hold all such payments and cash proceeds received by it in trust for and as the property of the Lender and shall not commingle such property with any of its other funds or property. All deposits in the Collateral Account shall constitute proceeds of
Collateral and shall not constitute payment of the Obligations. 
 (ii) All items deposited in the Collateral Account shall
be subject to final payment. If any such item is returned uncollected, the Borrower will immediately pay the Lender, or, for items deposited in the Collateral Account, the bank maintaining such account, the amount of that item, or such bank at its
discretion may charge any uncollected item to the commercial or other accounts. Borrower shall be liable as an endorser on all items deposited by it in the Collateral Account, whether or not in fact endorsed by it. 

(b) Application of Payments. 

(i) If a Collateral Account has been established and there are funds in the Collateral Account, the Borrower may, from time to
time, cause funds in the Collateral Account to be transferred to the Lender’s general account for payment of the Obligations. Except as provided in the preceding sentence, amounts deposited in the Collateral Account shall not be subject to
withdrawal by the Borrower, except after full payment and discharge of all Obligations and termination of the Credit Facility. 

(ii) All payments to the Lender shall be made in immediately available funds and shall be applied to the Obligations upon
receipt by the Lender. Funds received from the Collateral Account shall be deemed to be immediately available. The Lender may hold all payments not constituting immediately available funds for three (3) additional days before applying them to
the Obligations. 
 Section 2.12 Voluntary Prepayment; Reduction of the Maximum Line; Termination of the Credit Facility by the
Borrower. Except as otherwise provided herein, the Borrower may prepay the Advances in whole at any time or from time to time in part; provided that voluntary prepayments of the Real Estate Term Advance shall be in a minimum amount of
$250,000.00. The Borrower may terminate the Credit Facility or reduce the Maximum Line at any time if it (i) gives the Lender at least 30 days’ prior written notice and (ii) pays the Lender termination or Maximum Line reduction fees in
accordance with Section 2.9(e). Any reduction in the Maximum Line must be in an amount of not less than $500,000.00 or an integral multiple thereof. If the Borrower reduces the Maximum Line to zero, all Obligations shall be immediately due and

  
 24 

 
payable. Subject to termination of the Credit Facility and payment and performance of all Obligations, the Lender shall, at the Borrower’s expense, release or terminate the Security Interest
and the Security Documents to which the Borrower is entitled by law. 
 Section 2.13 Mandatory Prepayment. Without notice or
demand, if the sum of the outstanding principal balance of the Revolving Advances plus the L/C Amount shall at any time exceed the Borrowing Base, the Borrower shall (i) first, immediately prepay the Revolving Advances to the extent necessary
to eliminate such excess; and (ii) if prepayment in full of the Revolving Advances is insufficient to eliminate such excess, pay to the Lender in immediately available funds for deposit in the Special Account an amount equal to the remaining
excess. Any payment received by the Lender under this Section 2.13, or under Section 2.12, may be applied to the Obligations, in such order and in such amounts as the Lender, in its discretion, may from time to time determine. 

Section 2.14 Revolving Advances to Pay Obligations. Notwithstanding anything in Section 2.1, the Lender may, in its
discretion at any time or from time to time, without the Borrower’s request and even if the conditions set forth in Section 4.2 would not be satisfied, make a Revolving Advance in an amount equal to the portion of the Obligations from time
to time due and payable. 
 Section 2.15 Use of Proceeds. The Borrower shall use the proceeds of Advances and each Letter of
Credit for ordinary working capital purposes and for any other business purposes determined by Borrower. 
 Section 2.16 Liability
Records. The Lender may maintain from time to time, at its discretion, records as to the Obligations. All entries made on any such record shall be presumed correct until the Borrower establishes the contrary. Upon the Lender’s demand, the
Borrower will admit and certify in writing the exact principal balance of the Obligations that the Borrower then asserts to be outstanding. Any billing statement or accounting rendered by the Lender shall be conclusive and fully binding on the
Borrower unless the Borrower gives the Lender specific written notice of exception within 30 days after receipt. 
 Section 2.17
Appraisals. Appraisals; Environmental Site Assessments. Borrower shall reimburse the Lender for Lender’s fees, costs and expenses incurred in connection with (i) one appraisal which is performed on the Real Property after
June 30, 2013, (ii) one appraisal per year which is performed on Equipment, (iii) one appraisal per year which is performed on Inventory, and (iv) any appraisals performed during the existence of an Event of Default or Default

(collectively referred to as the “Security Interest”) in the Collateral, as security for the payment and performance of the Obligations. Upon request by the Lender, the Borrower will grant the Lender a security interest in all commercial
tort claims it may have against any Person. Notwithstanding anything herein or in any other Loan Document to the contrary, in no event shall the Security Interest attach to, or the term “Collateral” be deemed to include (a) any of the

of a Borrower; (c) any lease, license, contract, property rights or agreement to which a Borrower is a party or any of such Borrower’s rights or interests thereunder, if, and for so long as and to the extent that, the grant of the security
interest would constitute or result in (i) the abandonment, invalidation or unenforceability of any material right, title or interest of such Borrower therein, or (ii) a breach or termination pursuant to the terms of, or a default under,
any such lease, license, contract, property rights or agreement (other than to the extent that any such breach, termination or default would be rendered ineffective pursuant to Section 9-406, 9-407, 9-408 or 9-409 of the Uniform Commercial Code

an equity interest in an entity other than a Subsidiary of any Borrower, solely to the extent such acquisition is permitted under this Agreement, if the terms of the organizational documents of the issuer of such equity interests do not permit the
grant of the security interest in such equity interests by the owner thereof or the applicable Borrower, after employing commercially reasonable efforts, has been unable to obtain any approval or consent to the creation of the security interest
therein that is required under such organizational documents, and (e) any application to register any trademark or service mark prior to the filing under applicable law of a verified statement of use (or the equivalent) for such trademark or
service mark to the extent the creation of a security interest therein or the grant of a mortgage thereon would void or invalidate such trademark or service mark. 

Section 3.2 Notification of Account Debtors and Other Obligors. The Lender may at any time during a Default Period notify any
account debtor or other person obligated to pay the amount due that such right to payment has been assigned or transferred to the Lender for security and shall be paid directly to the Lender. The Borrower will join in giving such notice if the

hereafter covering the Collateral or any evidence thereof or any business records or valuable papers pertaining thereto, and the Borrower hereby directs the issuer of any such policy to pay all such monies directly to the Lender. At any time,
whether or not a Default Period then exists, the Lender may (but need not), in the Lender’s name or in the Borrower’s name, execute and deliver proof of claim, receive all such monies, endorse checks and other instruments representing

Section 6.27 Transactions with Affiliates. Neither the Borrower nor any of its Subsidiaries will engage in any transaction with
any of such Person’s Affiliates, except (a) for reasonable allocations of overhead to such Affiliate; (b) in the ordinary course of business, 

  
 47 

 
pursuant to the reasonable requirements of such Person’s business, upon fair and reasonable terms no less favorable to such Person than such Person would obtain in a comparable arms’
length transaction, and with the obligations owing to the Affiliate fully subordinated to the Obligations pursuant to a subordination agreement executed by the Affiliate and the Lender in form and substance satisfactory to the Lender; and the
transactions described in Schedule 6.27. 
 Section 6.28 Proceeds of Sale, Loss, Destruction or Condemnation of
Collateral. Except as provided in Section 6.17, if the Borrower or any of its Subsidiaries sells any of the Collateral or if any of the Collateral is lost or destroyed or taken by condemnation, the Borrower shall, unless otherwise agreed by
Lender, pay to Lender as and when received by the Borrower or such Subsidiary and as a mandatory reduction of the outstanding principal balance of the Revolving Advances (and if such Collateral consists of Real Property, (x) with a
corresponding permanent reduction in the Real Estate Sublimit component of the Borrowing Base and (y) as a mandatory prepayment of the Real Estate Term Advance of all excess proceeds (if any) after application to the Revolving Advances in an
amount not to exceed the amount of Revolving Advances attributable to the Real Estate Sublimit), a sum equal to the proceeds (including insurance payments but net of reasonable costs and taxes incurred in connection with such sale or event) received
by the Borrower or such Subsidiary from such sale, loss, destruction or condemnation. Notwithstanding the foregoing, if the proceeds of insurance (net of reasonable costs and taxes incurred) with respect to any loss or destruction of Equipment or
Inventory (i) are less than $1,000,000.00, unless an Event of Default or Default Period is then in existence, the Lender shall remit such proceeds to the Borrower for use in replacing or repairing the damaged Collateral, or (ii) are equal
to or greater than $1,000,000.00 and the Borrower has requested that the Lender agree to permit the Borrower or the applicable Subsidiary to repair or replace the damaged Collateral, such amounts may, with the consent of the Lender, be remitted to
the Borrower to permit such repair or replacement under this clause (ii); provided that such amounts shall remain deposited at all times in the Collateral Account and, to the extent the Borrower or its respective Subsidiary has not used such amounts
to repair or replace such damaged Collateral within one-hundred eighty (180) days after the Borrower’s receipt thereof, such amounts shall be paid to the Lender for application to the outstanding principal balance of the Revolving
Advances.

it is governed, or under any material lease or other contract, and the expiration of the applicable period of grace, if any, specified in such evidence of indebtedness, indenture, other instrument, lease or contract, provided that only in the case
of a default which does not involve the failure to pay a monetary obligation or a default which can be cured by the payment of money alone, the default must also permit acceleration of the obligations under such agreement or the termination of such
agreement; 
 (j) Any Reportable Event, which the Lender determines in good faith might constitute grounds for the
termination of any Pension Plan of the Borrower or any of its Subsidiaries or for the appointment by the appropriate United States District Court of a trustee to administer any Pension Plan, shall have occurred and be continuing 30 days after

otherwise fail to operate its business in the ordinary course, or sell or attempt to sell all or substantially all of its assets, without the Lender’s prior written consent; 

(m) Default in the payment of any amount owed by the Borrower or any of its Subsidiaries to the Lender other than any

Section 7.2 Rights and Remedies. During any Default Period, the Lender may exercise any or all of the following rights and
remedies: 
 (a) the Lender may, by notice to the Borrower, declare the Commitment to be terminated, whereupon the same shall
forthwith terminate; 
 (b) the Lender may, by notice to the Borrower (the “Actual Acceleration Notice”), declare
the Obligations to be forthwith due and payable, whereupon all Obligations shall become and be forthwith due and payable, without demand, presentment, protest, or other notice of any kind (including, without limitation, notice of dishonor, notice of
default, and notice of intent to accelerate the maturity of the Obligation), all of which the Borrower waives except for the Actual Acceleration Notice; 

(c) the Lender may, without notice to the Borrower and without further action, apply any and all money owing by the Lender to
the Borrower to the payment of the Obligations; 
 (d) the Lender may exercise and enforce any and all rights and remedies
available upon default to a secured party under the UCC, including the right to take possession of Collateral, or any evidence thereof, proceeding without judicial process or by judicial process (without a prior hearing or notice thereof, which the
Borrower hereby expressly waives) and the right to sell, lease or otherwise dispose of any or all of the Collateral (with or without giving any warranties as to the Collateral, title to the Collateral or similar warranties), and, in connection
therewith, the Borrower will on demand assemble the Collateral given by and make it available to the Lender at a place to be designated by the Lender which is reasonably convenient to both parties; 

(e) the Lender may make demand upon the Borrower and, forthwith upon such demand, the Borrower will pay to the Lender in
immediately available funds for deposit in the Special Account pursuant to Section 2.5, an amount equal to the aggregate maximum amount available to be drawn under all Letters of Credit then outstanding, assuming compliance with all conditions
for drawing thereunder; 
 (f) the Lender may exercise and enforce its rights and remedies under the Loan Documents; and 

(g) the Lender may exercise any other rights and remedies available to it by law or agreement. 

  
 51 

 Notwithstanding the foregoing or anything to the contrary in any of the other Loan Documents, upon the occurrence
of an Event of Default described in subsections (e) or (f) of Section 7.1, the Obligations shall be immediately due and payable automatically without presentment, demand, protest or notice of any kind; provided, however, that in the
case of an involuntary petition resulting in an Event of Default under subsection (f) of Section 7.1, the Obligations shall be immediately due and payable automatically on the Full Remedies Date without demand, presentment, protest, or
notice of any kind (including, without limitation, notice of dishonor, notice of default, notice of intent to accelerate the maturity of the Obligation and actual notice of acceleration), all of which the Borrower waives without presentment, demand,
protest or notice of any kind. If the Lender sells any of the Collateral on credit, the Obligations will be reduced only to the extent of payments actually received. If the purchaser fails to pay for the Collateral, the Lender may resell the
Collateral and shall apply any proceeds actually received to the Obligations. 
 Section 7.3 Certain Notices. If notice to the
Borrower of any intended disposition of Collateral or any other intended action is required by law in a particular instance, such notice shall be deemed commercially reasonable if given (in the manner specified in Section 8.3) at least ten
calendar days before the date of intended disposition or other action. 
 ARTICLE VIII 

MISCELLANEOUS 

Section 8.1 No Waiver; Cumulative Remedies; Compliance with Laws. No failure or delay by the Lender in exercising any right, power
or remedy under the Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy
under the Loan Documents. The remedies provided in the Loan Documents are cumulative and not exclusive of any remedies provided by law. The Lender may comply with any applicable state or federal law requirements in connection with a disposition of
the Collateral and such compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral. 

Section 8.2 Amendments, Etc. No amendment, modification, termination or waiver of any provision of any Loan Document or consent to
any departure by the Borrower therefrom or any release of a Security Interest shall be effective unless the same shall be in writing and signed by the Lender, and then such waiver or consent shall be effective only in the specific instance and for
the specific purpose for which given. No notice to or demand on the Borrower in any case shall entitle such Person or any other Person to any other or further notice or demand in similar or other circumstances. 

Section 8.3 Addresses for Notices; Requests for Accounting. Except as otherwise expressly provided herein, all notices, requests,
demands and other communications provided for under the Loan Documents shall be in writing and shall be (a) personally delivered, (b) sent by first class United States mail, (c) sent by overnight courier of national reputation, or (d)
transmitted by telecopy, in each case addressed or telecopied to the party to whom notice is being given at its address or telecopier number as set forth below next to its signature or, as to each party, at such other address or telecopier number as
may hereafter be designated by such party in a written notice to the other party complying as to delivery with the terms of this Section. All such notices, requests, demands and other communications shall be deemed to have been given on (a) the
date received if personally delivered, (b) when deposited in the mail if delivered 

  
 52 

 
by mail, (c) the date sent if sent by overnight courier, or (d) the date of transmission if delivered by telecopy, except that notices or requests to the Lender pursuant to any of the
provisions of Article II shall not be effective until received by the Lender. All requests under Section 9-210 of the UCC (i) shall be made in a writing signed by a person authorized under Section 2.2(b), (ii) shall be personally
delivered, sent by registered or certified mail, return receipt requested, or by overnight courier of national reputation (iii) shall be deemed to be sent when received by the Lender and (iv) shall otherwise comply with the requirements of
Section 9-210. The Borrower requests that the Lender respond to all such requests which on their face appear to come from an authorized individual and releases the Lender from any liability for so responding. The Borrower shall pay Lender the
maximum amount allowed by law for responding to such requests. 
 Section 8.4 Further Documents. The Borrower will from time to
time execute and deliver or endorse any and all instruments, documents, conveyances, assignments, security agreements, mortgages, deeds of trust, financing statements, control agreements and other agreements and writings that the Lender may
reasonably request in order to secure, protect, perfect or enforce the Security Interest or the Lender’s rights under the Loan Documents (but any failure to request or assure that the Borrower executes, delivers or endorses any such item shall
not affect or impair the validity, sufficiency or enforceability of the Loan Documents and the Security Interest, regardless of whether any such item was or was not executed, delivered or endorsed in a similar context or on a prior occasion). 

Section 8.5 Costs and Expenses. The Borrower shall pay on demand all costs and expenses, including reasonable attorneys’
fees, incurred by the Lender or its Affiliates in connection with the Obligations, this Agreement, the Loan Documents, any Letter of Credit and any other document or agreement related hereto or thereto, and the transactions contemplated hereby,
including all such costs, expenses and fees incurred in connection with the negotiation, preparation, execution, amendment, administration, performance, collection and enforcement of the Obligations and all such documents and agreements and the
creation, perfection, protection, satisfaction, foreclosure or enforcement of the Security Interest. 
 Section 8.6 Indemnity.
In addition to the payment of expenses pursuant to Section 8.5, the Borrower shall indemnify, defend and hold harmless the Lender, and any of its participants, parent corporations, subsidiary corporations, affiliated corporations, successor
corporations, and all present and future officers, directors, employees, attorneys and agents of the foregoing (the “Indemnitees”) from and against any of the following (collectively, “Indemnified Liabilities”): 

(i) any and all transfer taxes, documentary taxes, assessments or charges made by any governmental authority by reason of the
execution and delivery of the Loan Documents or the making of the Advances; 
 (ii) any claims, loss or damage to which any
Indemnitee may be subjected if any representation or warranty contained in Section 5.14 proves to be incorrect in any respect or as a result of any violation of the covenant contained in Section 6.11(b); and 

(iii) except to the extent arising from judgments in favor of the Borrower against the Lender on account of the Lender’s

  
 53 

 
breach of its obligations under this Agreement, any and all other liabilities, losses, damages, penalties, judgments, suits, claims, costs and expenses of any kind or nature whatsoever (including
the reasonable fees and disbursements of counsel) in connection with the foregoing and any other investigative, administrative or judicial proceedings, whether or not such Indemnitee shall be designated a party thereto, which may be imposed on,
incurred by or asserted against any such Indemnitee, in any manner related to or arising out of or in connection with the making of the Advances and the Loan Documents or the use or intended use of the proceeds of the Advances. 

If any investigative, judicial or administrative proceeding arising from any of the foregoing is brought against any Indemnitee, upon such Indemnitee’s
request, the Borrower, or counsel designated by the Borrower and satisfactory to the Indemnitee, will resist and defend such action, suit or proceeding to the extent and in the manner directed by the Indemnitee, at the Borrower’s sole costs and
expense. Each Indemnitee will use its best efforts to cooperate in the defense of any such action, suit or proceeding. If the foregoing undertaking to indemnify, defend and hold harmless may be held to be unenforceable because it violates any law or
public policy, the Borrower shall nevertheless make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. The Borrower’s obligation under this Section 8.6
shall survive the termination of this Agreement and the discharge of the Borrower’s other obligations hereunder. 
 Section 8.7
Participants. The Lender and its participants, if any, are not partners or joint venturers, and the Lender shall not have any liability or responsibility for any obligation, act or omission of any of its participants. All rights and powers
specifically conferred upon the Lender may be transferred or delegated to any of the Lender’s participants, successors or assigns. 

Section 8.8 Execution in Counterparts: Electronic Transmission. This Agreement and other Loan Documents may be executed in any
number of counterparts, each of which when so executed and delivered shall be deemed to be an original and all of which counterparts, taken together, shall constitute but one and the same instrument. Delivery of an executed counterpart of this
Agreement by telefacsimile or electronic transmission shall be equally as effective as delivery of an original executed counterpart of this Agreement. Any party delivering an executed counterpart of this Agreement by telefacsimile or electronic
transmission also shall deliver an original executed counterpart of this Agreement but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Agreement. 

Section 8.9 Retention of Borrower’s Records. The Lender shall have no obligation to maintain any electronic records or any
documents, schedules, invoices, agings, or other papers delivered to the Lender by the Borrower or in connection with the Loan Documents for more than four months after receipt by the Lender. 

Section 8.10 Binding Effect; Assignment; Complete Agreement; Exchanging Information. The Loan Documents shall be binding upon and
inure to the benefit of the Borrower and the Lender and their respective successors and assigns, except that the Borrower shall not have the right to assign its rights thereunder or any interest therein without the Lender’s prior written
consent. To the extent permitted by law, the Borrower waives and will not 

  
 54 

 
assert against any assignee any claims, defenses or set-offs which the Borrower could assert against the Lender. This Agreement shall also bind all Persons who become a party to this Agreement as
a borrower. THIS AGREEMENT, TOGETHER WITH THE LOAN DOCUMENTS, COMPRISES THE COMPLETE AND INTEGRATED AGREEMENT OF THE PARTIES ON THE SUBJECT MATTER THEREOF AND SUPERSEDES ALL PRIOR AGREEMENTS, WRITTEN OR ORAL, ON THE SUBJECT MATTER THEREOF; AND MAY
NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS BETWEEN THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES. Without limiting the Lender’s right to share information regarding the
Borrower and its Affiliates with the Lender’s participants, accountants, participant’s accountants, lawyers, participant’s lawyers and Lender’s and participant’s other advisors, the Lender, Wells Fargo & Company,
and all direct and indirect subsidiaries of Wells Fargo & Company, may exchange any and all information they may have in their possession regarding the Borrower and its Affiliates, and the Borrower waives any right of confidentiality it may
have with respect to such exchange of such information. 
 Section 8.11 Severability of Provisions. Any provision of this
Agreement which is prohibited or unenforceable shall be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof. 

Section 8.12 Headings. Article, Section and subsection headings in this Agreement are included herein for convenience of reference
only and shall not constitute a part of this Agreement for any other purpose. 
 Section 8.13 Governing Law; Jurisdiction, Venue;
Waiver of Jury Trial. Except as expressly provided in another Loan Document, the Loan Documents shall be governed by and construed in accordance with the substantive laws (other than conflict laws) of the State of Arizona. The parties hereto
hereby (i) consent to the personal jurisdiction of the state and federal courts located in the State of Arizona in connection with any controversy related to this Agreement; (ii) waive any argument that venue in any such forum is not
convenient, (iii) agree that any litigation initiated by the Lender or the Borrower in connection with this Agreement or the other Loan Documents may be venued in either the State or Federal courts located in Maricopa County, Arizona; and
(iv) agree that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. 

Section 8.14 Co-Borrowers. 

(a) All Advances may be made solely to, and all Letters of Credit may be issued for solely the account of, Schuff
International, at the Lender’s election, any other Person comprising the Borrower; and in such case they shall be deemed received by all Persons comprising the Borrower. Any payments on the Advances received by the Lender shall be credited to
the Advances for the benefit of all Persons comprising the Borrower. It is expressly agreed and understood by each Person comprising the Borrower that Lender shall have no responsibility to inquire into the apportionment, allocation or disposition
of any Advances made to another Borrower. Each Person comprising the Borrower hereby irrevocably appoints Schuff International and each other Borrower as its agent and attorney-in-fact for all purposes of the Loan Documents, including, without
limitation, the giving and receiving of notices and other communications, the making of requests for Advances and Letters of Credit, the execution and delivery of certificates and the receiving and allocating of Advances from the Lender. 

  
 55 

 (b) Each Person comprising the Borrower represents and warrants to Lender that
the joint handling of the Loan is jointly desired by all Persons comprising the Borrower. Each Person comprising the Borrower expects to derive benefit, directly or indirectly, from the joint borrowing. 

(c) Neither demand on, nor the pursuit of any remedies against, any Borrower shall be required as a condition precedent to, and
neither the pendency nor the prior termination of any action, suit or proceeding against any other Borrower (whether for the same or a different remedy) shall bear on or prejudice the making of a demand on any Borrower by the Lender and commencement
against any other Borrower after such demand, of any action, suit or proceeding, at law or in equity, for the specific performance of any covenant or agreement contained herein or for the enforcement of any other appropriate legal or equitable
remedy. 
 (d) Each Person comprising the Borrower agrees to perform the Obligations of the other Persons comprising the
Borrower, whether or not it is a party to the Loan Document creating the Obligations. Each Borrower’s liability under the Loan Documents is primary, direct, immediate, joint and several with that of the other Persons comprising the Borrower.
Neither (i) the exercise or the failure to exercise by the Lender of any rights or remedies conferred on it under the Loan Documents, hereunder or existing at law or otherwise, or against any security for performance of the Obligations,
(ii) the commencement of an action at law or the recovery of a judgment at law against any other Borrower or any surety and the enforcement thereof through levy or execution or otherwise, (iii) the taking or institution or any other action
or proceeding against any other Borrower or any surety nor (iv) any delay in taking, pursuing or exercising any of the foregoing actions, rights, powers or remedies (even though requested by any of the Persons comprising Borrower) by Lender or
anyone acting for the Lender, shall extinguish or affect the obligations of any of the Persons comprising the Borrower under the Loan Documents. 

(e) Each Borrower hereby expressly waives: (i) all diligence in collection or protection of or realization on the
Obligations or any part thereof, any obligation hereunder, or any security for or guarantee of any of the foregoing; (ii) any defense based upon a marshaling of assets; (iii) any defense arising because of the Lender’s election under
Section 1111 (b)(2) of the United States Bankruptcy Code (“Bankruptcy Code”) in any proceeding instituted under the Bankruptcy Code; (iv) any defense based on post-petition borrowing or the grant of a security interest by any
other Borrower under Section 364 of the Bankruptcy Code; (v) any duty on the part of the Lender to disclose to any other Person comprising Borrower any facts Lender may now or hereafter know about any other Person comprising the Borrower,
regardless of whether Lender has reason to believe that any such facts materially increase the risk beyond that which such Person intends to assume or has reason to believe that such facts are known such Person or has a reasonable opportunity to
communicate such facts to such Person, because each Person comprising the Borrower represents and warrants that it is fully responsible for being and keeping informed of the financial condition 

  
 56 

 
of the other Persons comprising the Borrower and of all circumstances bearing on the risk of non-payment of any Obligations; (vi) any and all suretyship defenses and defenses in the nature
thereof under Arizona and/or any other applicable law, including, without limitation, the benefits of the provisions of Sections 12-1641 through 12-1646, of the Arizona Revised Statutes, Sections 17 and 21, A.R.C.P., and all other laws of
similar import; and (vii) all rights and defenses arising out of an election of remedies by the Lender, even though that election of remedies, such as a nonjudicial foreclosure with respect to security for a guaranteed obligation, has destroyed
the Person’s rights of subrogation and reimbursement against the principal by the operation of law or otherwise. 
 (f)
Each Person comprising the Borrower agrees that it will not assert against the Lender any defense of waiver, release, discharge in bankruptcy, statute of limitations, res judicata, statute of frauds, anti-deficiency statute, fraud, usury,
illegality or unenforceability which may be available to the other Persons comprising the Borrower with respect to the Loan Documents (or the Loan), or any set off available to the other Persons comprising the Borrower against the Lender, whether or
not on account of a related transaction. 
 (g) The benefits, remedies and rights provided or intended to be provided hereby
for the Lender are in addition to and without prejudice to any rights, benefits, remedies or security to which the Lender might otherwise be entitled. 

(h) Anything else contained herein to the contrary notwithstanding, the Lender, from time to time, without notice to any
Borrower, may take all or any of the following actions without in any manner affecting or impairing the obligations of any other Borrower under the Loan Documents: (i) obtain a lien on or a security interest in any property to secure any of the
Obligations, either consensually or by operation of law; (ii) retain or obtain the primary or secondary liability of any Person(s), in addition to the Persons comprising the Borrower, with respect to any of the Obligations; (iii) renew,
extend or otherwise change the time for payment or performance of any of the Obligations for any period; (iv) release or compromise any liability of the other Persons comprising the Borrower under the Loan Documents or any liability of any
nature of any other person(s) with respect to the Obligations; (v) exchange, enforce, waive, release and apply any security for the performance of the Obligations and direct the order or manner of the proceeds of such security for any of the
Obligations, whether or not the Lender shall proceed against any other Person primarily or secondarily liable on any of the Obligations; (vi) agree to any amendment (including, without limitation, any amendment which changes the amount of
interest to be paid under the Loan Documents or extends the period of time during which the other Persons comprising the Borrower may obtain Advances or Letters of Credit) to the Loan Documents or any waiver of any provisions of the Loan Documents
and/or exercise the Lender’s rights to consent to any action or non-action of the Lender which may violate the covenants and agreements contained in the Loan Documents with or without consideration, on such terms and conditions as may be
acceptable to the Lender in Lender’s discretion; or (vii) exercise any of the Lender’s rights conferred by the Loan Documents or by law. 

  
 57 

 (i) If at any time all or any part of any payment theretofore applied by the
Lender to any of the Obligations is or must be rescinded or returned by the Lender for any reason whatsoever (including, without limitation the insolvency, bankruptcy or reorganization of any of the Persons comprising the Borrower), such
Obligations, for purposes of this Agreement, to the extent that such payment is or must be rescinded or returned, shall be deemed to have never been performed. 

(j) To the extent not prohibited by law, until the Obligations have been paid and performed in full and Lender has no further
obligation to extend credit to any Borrower under the Loan Documents, each Person comprising the Borrower shall have no right of subrogation with respect to the Obligations or any rights of indemnification, reimbursement or contribution from any
other Person comprising the Borrower or from any surety with respect to the Obligations regardless of any payment made by such Person with respect to the Obligations of the other Persons comprising the Borrower; and such Person hereby
unconditionally waives any such right of subrogation, indemnification, reimbursement or contribution for such period. 
 (k)
Each Borrower agrees that they shall not have or assert any such rights against one another or their respective successors and assigns or any other party (including any surety), either directly or as an attempted set off to any action commenced
against the other Persons comprising the Borrower or any other Person. Each of the Persons comprising the Borrower hereby acknowledges and agrees that this waiver is intended to benefit the other Persons comprising the Borrower and shall not limit
or otherwise affect any of such Persons liabilities under any Loan Document, or the enforceability hereof or thereof. 
 (l)
The obligations of the Persons comprising the Borrower in this Agreement are joint and several. 
 Section 8.15 Effect of
Agreement. This Agreement shall become effective only upon the satisfaction of all of the conditions contained within Section 4.3 hereof. At such time as this Agreement becomes effective, it shall in all respects supersede the Original
Amended and Restated Credit Agreement, and all Advances (past, present and future) made by the Lender to the Borrower shall in all respects be governed by this Agreement. Until such time as all of the conditions contained in Section 4.3 have

construction industry, the Company’s employees from time to time become subject to injury, or even death, while employed by the Company. Except as noted below, the Company does not believe there are any such contingencies at August 13,
2013 for which the eventual outcome would have a material adverse impact on the financial position, results of operations or liquidity of the Company. 

In December 2012, two lawsuits were filed against our subsidiaries that involve fabrication work pertaining to a refinery in Whiting, Indiana
(“BP Refinery”), owned by a subsidiary of British Petroleum (“BP”). In December 2012, BP brought suit in the United States District Court for the Northern District of Indiana (the “Indiana suit”) against Carboline
Company (“Carboline”), Trinity Steel Fabricators, Inc. (“Trinity”), our subsidiary, Schuff Steel Company (“Schuff”), Tecon Services, Inc. (“Tecon”) and Alfred Miller Contracting Company (“AMC”),
asserting contract and warranty claims as to Schuff, arising out of allegations that fireproofing applied to steel that Schuff and Trinity supplied to a modernization project at the BP Refinery was defectively fireproofed. The steel fabricators,
Trinity and a Schuff subsidiary, subcontracted the application of the Pyrocrete® 241 to AMC and/or Tecon. These applicators purchased the Pyrocrete® 241 from the manufacturer, Carboline. BP alleges that the Pyrocrete® 241 is defective
and causing damage to BP’s property and that the defects are caused by the preparation or application of the Pyrocrete® 241, or by defects in the product itself. BP alleges that it has and will continue to incur substantial damages. BP has
not quantified its damages; however, they are believed to be at least in the tens of millions of dollars. Remediation of the fireproofing has commenced but is not expected to be completed for some time, and total alleged damages will remain
uncertain until that work is completed. 
 Also in December 2012, AMC and Tecon filed a Petition for Damages and Declaratory Judgment in the
State Court of Louisiana (14th Judicial District Court, Parish of Calcasieu) (the “Louisiana suit”), against Carboline, BP Corporation North America Inc., BP Products North America, Inc.
(collectively referred to as “BP entities”), Foster Wheeler USA Corporation, Fluor Enterprises, Inc, Trinity, our subsidiaries, Schuff and Schuff Steel – Gulf Coast, Inc. (“Gulf Coast”), Dynamic Industries, Inc.
(“DII”) and Land Coast Insulation, Inc. (“Landcoast”). AMC and Tecon allege, among other claims, that the Carboline Pyrocrete® 241 on the BP Refinery project was defective and that Carboline breached warranties relating to it
and made negligent and fraudulent misstatements concerning that product. AMC and Tecon also seek a court determination of the rights and responsibilities of the parties involved in the procurement, application, inspection, assembly and/or
fabrication of the structural steel that had Pyrocrete® 241 applied to it. 
 The Schuff entities have filed answers and cross-claims in
both lawsuits denying liability to BP and seeking indemnification and recovery on warranty from AMC and Tecon to the extent of any improper application and from Carboline to the extent any defect in the Pyrocrete® 241 when it was applied.
Numerous complex procedural and substantive legal and factual issues have yet to be resolved. Formal discovery has just commenced. Schuff and Gulf Coast intend to aggressively defend themselves in this matter. 

On February 9, 2009, the Roosevelt Irrigation District (“RID”) brought suit in the United States District Court for the
District Court of Arizona against Salt River Project Agricultural 

 
Improvement and Power District and approximately one-hundred other defendants, including our subsidiary, Schuff Steel Company (“Schuff”). RID operates one-hundred groundwater wells in
western Maricopa County and contends that approximately twenty of its wells are contaminated. RID asserts recovery against the defendants under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended
(“CERCLA” or “Superfund”) for the recovery of costs incurred by RID in responding to the defendants’ alleged releases or threatened releases of hazardous substances into groundwater that allegedly impact or threaten to
impact the groundwater in the West Van Buren area of Phoenix, Arizona. RID has submitted an Early Response Action (“ERA”) to the Arizona Department of Environmental Quality (“ADEQ”) and has asserted future potential remediation
costs in excess of $40,000,000. ADEQ received substantial public comment against the ERA. In July 2010, the ADEQ granted conditional approval to RID’s remediation plan with a substantial number of conditions and milestones. Accordingly, RID
amended its complaint and Schuff was served with the first amended complaint in late July 2010. Initially, most defendants filed either various motions to dismiss RID’s complaint or motions for summary judgment based on certain legal theories
but the Court dismissed these motions without prejudice to focus on substantial motions to disqualify counsel for RID based upon various conflicts of interest with RID’s chosen counsel. The Court granted certain motions by five defendants to
disqualify RID’s counsel by order dated August 26, 2011. In RID’s counsel recently withdrew from representation and RID has retained new counsel. Schuff consistently had denied any liability to RID and was aggressively defending
itself against any allegation that its operations contaminated the groundwater. On July 29, 2013, RID’s new counsel submitted a Second Amended Complaint which dropped Schuff Steel as a defendant. It is possible that a current defendant
could file a third-party claim against Schuff Steel Company at some future date. 
 On February 5, 2010, Silver Steel, Inc.
(“Silver”) brought suit in Clark County, Nevada District Court (the “Court”) against our subsidiary Schuff Steel Company (“Schuff) and our bonding company. Silver acted as second tier subcontractor to Schuff on the Sobella
Retail project (“project”), which was part of the City Center Project in Las Vegas, Nevada. Silver agreed in October, 2007, to a fixed price of approximately $1,483,000 to perform metal deck installation and to perform extra work at agreed
upon hourly rates. During the project, Silver submitted over 500 extra work orders (“EWO”), which were then bundled into proposed change orders (“PCO”). Twenty-four executed change orders were issued totaling approximately
$3,305,000, for a total adjusted contract of approximately $4,788,000. Schuff has paid the adjusted contract value. Silver completed construction of the base scope of its work in August 2008. It performed extra work on the project into January 2009.
Silver never complained during the project about any unpaid extra work or alleged impacts. Thereafter, on February 26, 2009, Silver first gave Schuff notice of a claim in PCO 43, in the amount of $666,000. Schuff arranged for Silver to present
its claim to Perini Construction Company (“Perini”), the general contractor, which denied the claim, in part because there was no backup presented by Silver. Schuff claims that it was prejudiced by the late claim, because if it had been
put on notice of an impact during the course of the project, it could have taken action to minimize the impact or to pass the claim upstream to Perini or the owner. Silver’s initial claims in the litigation were for breach of contract, among
other legal theories, against Schuff for allegedly unpaid work and its alleged damages, which had increased to $2,433,000. Schuff has denied any liability. In November 2011, Silver increased its total cost claim for damages to approximately
$4,300,000. Trial in this matter occurred between February 7 and 21, 2012. By Order dated July 16, 2013, The Court issued a decision finding in favor of Schuff Steel Company on the extra work claim, but found that Schuff Steel still owed
Silver Steel the amount of $112,155 on its contract balance. On August 5, 2013, Schuff filed a motion to amend the judgment on the grounds that the Court made an error in adding the amounts paid to Silver and that Silver had, in fact, been

  
 2 

 
paid in full for the contract balance. A hearing on this matter is scheduled for September 5, 2013. Schuff also intends to file a motion to recover a portion of its attorneys’ fees and
costs on the grounds that Silver did not exceed the amount Schuff had submitted an offer of judgment to Silver prior to trial in this matter. The matter is not yet ripe for appeal. 

The Company is self-insured for its employees’ workers’ compensation claims. Under provisions of the policies, the Company has purchased stop/loss
insurance to mitigate its risks against catastrophic injury-related events. The stop/loss amount for workers’ compensation is $350,000 per employee per accident. At December 31, 2012 and 2011, the Company had an accrual of approximately
$2,426,000 and $2,581,000, respectively, for workers’ compensation claims incurred but not paid or reported and for future claims from injuries existing at year-end. 

The Company had approximately $28,181,000 of performance bonds issued on its behalf as of December 31, 2012. The performance bonds were
required by various general contractors to guarantee the Company’s performance on projects.

 Schedule 6.27 (Transactions with Affiliates) 

Since its inception, the Company has maintained business relationships and engaged in certain transactions with the affiliated companies and
parties described below. Since the closing of its initial public offering in July 1997, all transactions between the Company and its affiliated entities, executive officers, directors, or significant stockholders have been approved by a majority of
the non-employee directors of the Company. The Company also believes these transactions were on terms that were no less favorable to the Company than the Company could have obtained from non-affiliated parties. 

The Company leases its fabrication and office facilities located at 420 S. 19th Avenue,
Phoenix, AZ 85009 from 19th Avenue/Buchanan Limited Partnership, an Arizona limited partnership (the “Schuff Partnership”). The general and limited partners of the Schuff Partnership are
David A. Schuff, Scott A. Schuff, and certain of their family members. David A. Schuff is a co-founder and the Chairman of the Board of Directors of the Company, and Scott A. Schuff is a Director and the President and Chief Executive Officer of the
Company. David A. Schuff and Scott A. Schuff presently are the beneficial owners of approximately 25.2% of the issued and outstanding common stock of the company including Treasury shares. 

The Company has one lease with the Schuff Partnership with a 20 year term and is subject to increases every five years based on increases in
the Consumer Price Index. All other terms and conditions remain unchanged. Rent expense with the related party leases during 2012 total $694,000.
