LEGAL_US_E # 147564565.6

--------------------------------------------------------------------------------

(c)Section 1.1 of the Credit Agreement is hereby amended by amending and
restating the following definitions in their entirety:

"Daily Three Month LIBOR" means for any day, the rate of interest equal to LIBOR
then in effect for delivery for a three (3) month period. When interest is
determined in relation to Daily Three Month LIBOR, each change in the interest
rate shall become effective each business day that Lender determines that Daily
Three Month LIBOR has changed. If such rate of interest is below 0.75%, then the
rate determined pursuant to this definition shall be deemed to be 0.75%.
"Floating Rate” means, with respect to all Advances an interest rate equal to
the sum of (i) Daily Three Month LIBOR, which interest rate shall change
whenever Daily Three Month LIBOR changes, plus (ii) the Margin Amount.

"Term Loan Maximum Amount" means the "Maximum Term Principal Obligations" as
defined in the Intercreditor Agreement (as in effect on the date hereof or as
amended pursuant to an amendment agreed to in writing by the Lender and the Term
Loan Agent (including that certain Second Amendment to Intercreditor Agreement
dated as of the Second Amendment Effective Date)).
(d)Section 1.1 of the Credit Agreement is hereby further amended by adding each
of the following defined terms in appropriate alphabetical order:
“DDTL” means the delayed draw term loan of up to $10,000,000 provided under the
Term Loan Credit Agreement on the Second Amendment Effective Date.
“Margin Amount” means, (a) if the financial statements of the Borrower and its
Subsidiaries in accordance with Section 6.1(a) or Section 6.1(b) for the four
fiscal quarter period of the Borrower and its Subsidiaries most recently ended
demonstrate that the Senior Leverage Ratio of the Borrower and its Subsidiaries
as of the end of such four fiscal quarter period or as of such funding date, is
less than 2:50:1.00, 1.75% per annum, and (b) if the financial statements of the
Borrower and its Subsidiaries in accordance with Section 6.1(a) or Section
6.1(b) for the four fiscal quarter period of the Borrower and its Subsidiaries
most recently ended demonstrate that the Senior Leverage Ratio of the Borrower
and its Subsidiaries as of the end of such four fiscal quarter period or as of
such funding date, is equal to or greater than 2:50:1.00, 2.00% per annum. Any
changes to the Margin Amount pursuant to clause (a) or (b) above shall take
effect two (2) Business Days after the applicable financial statements are
delivered or the funding of such DDTL occurs, as the case may be; provided that,
if the Borrowers fail to deliver on a timely basis such financial statements as
required under Section 6.1(a) or Section 6.1(b), the Margin Amount shall be as
set forth in clause (b) hereof; provided further, that any change in the Margin
Amount from the rates set forth in clause (a) above to the rates set forth in
clause (b) above shall not take effect until two (2) Business Days after the
later of (i) the date on which the applicable financial statements in accordance
with Section 6.1(a) or Section 6.1(b) are due, and (ii) the date on which such
financial statements are actually delivered. Notwithstanding the foregoing, in
the event that any financial statement or calculation described in the foregoing
proviso is inaccurate (regardless of whether the Agreement is in effect when
such inaccuracy is discovered), and such inaccuracy, if corrected, would have
led to the Margin Amount being calculated in accordance with clause (b) above,
then the Margin Amount for such period shall be adjusted retroactively (to the
effective date of the increase of the Margin Amount that was based upon the
delivery of such inaccurate financial statement or calculation) to reflect the
correct Margin Amount, and the Borrower shall promptly make payments to the
Lender to reflect such adjustment.

shareholders of DBM Global challenging the tender offer for the shares of DBM
Global that closed on October 6, 2014.

consecutive months during any fiscal year; provided that expenses related to the

Credit Agreement, a portion of the proceeds of the DDTL may be used by the
Borrower to declare and make a dividend or distribution to its shareholders to
pay liabilities and expenses associated with the Schuff Stockholder Litigation
so long as such dividend or distribution and the use of the proceeds of the DDTL
are expressly permitted under the Term Loan Credit Agreement as in effect as of
the Second Amendment Effective Date.
3.Waiver of Appraisals. The Lender waives any requirement that appraisals of
Inventory and Equipment shall have occurred for the fiscal year ended December
31, 2019. The Borrower agrees that Lender will conduct appraisals on Inventory
and Equipment, at the expense of the Borrower, in the fourth quarter of 2020.
4.Waiver of Event of Default. The Lender hereby waives the Event of Default that
arose as a result of the Borrower’s failure to deliver the December Monthly
Financial Statement on or before the deadline required under Section 6.1(b) of
the Credit Agreement (“Specified Event of Default”); provided, that nothing
herein, nor any communications among any Loan Party or Lender, shall be deemed a
waiver with respect to any Events of Default (other than the Specified Event of
Default), or any future failure of any Loan Party to comply fully with any
provision of the Credit Agreement or any provision of any other Loan Document,
and in no event shall this waiver be deemed to be a waiver of enforcement of any
the Lender’s rights or remedies under the Credit Agreement and the other Loan
Documents, at law (including under the UCC), in equity, or otherwise including,
without limitation, the right to declare all Obligations immediately due and
payable pursuant to Section 7.1 of the Loan Agreement, in each case with respect
to any other Defaults or Events of Default now existing or hereafter arising.
Except as expressly provided herein, the Lender hereby reserves and preserves
all of its rights and remedies against any Loan Party under the Credit Agreement
and the other Loan Documents, at law (including under the UCC), in equity, or
otherwise including, without limitation, the right to declare all Obligations
immediately due and payable pursuant to Section 7.1 of the Loan Agreement.

“Releasees”), from any and all past, present and future claims, suits, liens,
lawsuits, adverse consequences, amounts paid in settlement, debts, deficiencies,
diminution in value, disbursements, demands, obligations, liabilities, causes of
action, damages, losses, costs and expenses of any kind or character, whether

direct, indirect, or derivative, asserted or unasserted, matured or unmatured,
foreseen or unforeseen, past or present, liquidated or unliquidated, suspected
or unsuspected, occurring prior to the date hereof which relates, directly or

Documents, except for the duties and obligations set forth in this Amendment. As
to each and every Claim released hereunder, each Person comprising the Borrower
hereby represents that it has received the advice of legal counsel with regard
to the releases contained herein, and having been so advised, specifically
waives the benefit of the provisions of Section 1542 of the Civil Code of
California which provides as follows:
“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR
SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH
IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH
THE DEBTOR.”
As to each and every Claim released hereunder, each Person comprising the
Borrower also waives the benefit of each other similar provision of applicable
federal or state law (including without limitation the laws of the state of
Arizona), if any, pertaining to general releases after having been advised by
its legal counsel with respect thereto.
Each Person comprising the Borrower acknowledges that it may hereafter discover
facts different from or in addition to those now known or believed to be true
with respect to such Claims and agrees that this instrument shall be and remain
effective in all respects notwithstanding any such differences or additional
facts. Each Person comprising the Borrower understands, acknowledges and agrees

proceeding which may be instituted, prosecuted or attempted in breach of the
provisions of such release.
(b)Each Person comprising the Borrower, for itself and on behalf of its
successors, assigns, and officers, directors, employees, agents and attorneys,
and any Person acting for or on behalf of, or claiming through it, hereby

regulatory proceeding or otherwise) any Releasee on the basis of any Claim
released, remised and discharged by such Person pursuant to the above release.
Each Person comprising the Borrower further agrees that it shall not dispute the
validity or enforceability of the Credit Agreement or any of the other Loan
Documents or any of its obligations thereunder, or the validity, priority,
enforceability or the extent of the Lender’s Lien on
        6

--------------------------------------------------------------------------------

any item of Collateral under the Credit Agreement or the other Loan Documents.
If any Person comprising the Borrower or any of their respective successors,
assigns, or officers, directors, employees, agents or attorneys, or any Person
acting for or on behalf of, or claiming through it violate the foregoing
covenant, such Person, for itself and its successors, assigns and legal
representatives, agrees to pay, in addition to such other damages as any
Releasee may sustain as a result of such violation, all attorneys’ fees and
costs incurred by such Releasee as a result of such violation.
10.CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER; JUDICIAL REFERENCE PROVISION.
THIS AMENDMENT SHALL BE SUBJECT TO THE PROVISIONS REGARDING CHOICE OF LAW AND
VENUE, JURY TRIAL WAIVER AND JUDICIAL REFERENCE PROVISION SET FORTH IN SECTION

counterparts and by different parties on separate counterparts, each of which,
when executed and delivered, shall be deemed to be an original, and all of
which, when taken together, shall constitute but one and the same Amendment.
Delivery of an executed counterpart of this Amendment by telefacsimile or other
electronic method of transmission shall be equally as effective as delivery of
an original executed counterpart of this Amendment. Any party delivering an
executed counterpart of this Amendment by telefacsimile or other electronic
method of transmission also shall deliver an original executed counterpart of
this Amendment, but the failure to deliver an original executed counterpart
shall not affect the validity, enforceability, and binding effect of this
Amendment.
13.Effect on Loan Documents.
(a)The Credit Agreement, as amended hereby, and each of the other Loan Documents
shall be and remain in full force and effect in accordance with their respective
terms and hereby are ratified and confirmed in all respects. The execution,
delivery, and performance of this Amendment shall not operate, except as
expressly set forth herein, as a modification or waiver of any right, power, or
remedy of the Lender under the Credit Agreement or any other Loan Document.
Except for the amendments to the Credit Agreement expressly set forth herein,
the Credit Agreement and the other Loan Documents shall remain unchanged and in
full force and effect. The waivers, consents and modifications set forth herein
are limited to the specifics hereof (including facts or occurrences on which the
same are based), shall not apply with respect to any facts or occurrences other
than those on which the same are based, shall neither excuse any future
non-compliance with the Loan Documents nor operate as a waiver of any Default or
Event of Default, shall not operate as a consent to any further waiver, consent
or amendment or other matter under the Loan Documents, and shall not be
construed as an indication that any future waiver or amendment of covenants or
any other provision of the Credit Agreement will be agreed to, it being
understood that the granting or denying of any waiver or amendment which may
hereafter be requested by the Borrower remains in the sole and absolute
discretion of the Lender. To the extent that any terms or provisions of this
Amendment conflict with those of the Credit Agreement or the other Loan
Documents, the terms and provisions of this Amendment shall control.
(b)Upon and after the effectiveness of this Amendment, each reference in the
Credit Agreement to “this Agreement”, “hereunder”, “herein”, “hereof” or words
of like import referring to the Credit Agreement, and each reference in the
other Loan Documents to “the Credit Agreement”,
        7

--------------------------------------------------------------------------------

“thereunder”, “therein”, “thereof” or words of like import referring to the
Credit Agreement, shall mean and be a reference to the Credit Agreement as
modified and amended hereby.
(c)To the extent that any of the terms and conditions in any of the Loan
Documents shall contradict or be in conflict with any of the terms or conditions
of the Credit Agreement, after giving effect to this Amendment, such terms and
conditions are hereby deemed modified or amended accordingly to reflect the
terms and conditions of the Credit Agreement as modified or amended hereby.
(d)This Amendment is a Loan Document.
(e)THIS AMENDMENT SHALL BE SUBJECT TO THE RULES OF CONSTRUCTION SET FORTH IN
SECTION 1.2 OF THE CREDIT AGREEMENT, AND SUCH PROVISIONS ARE INCORPORATED HEREIN
BY THIS REFERENCE, MUTATIS MUTANDIS.

Credit Agreement and the other Loan Documents constitute the entire
understanding and agreement between the parties hereto with respect to the
subject matter hereof and supersede any and all prior or contemporaneous
amendments or understandings with respect to the subject matter hereof, whether
express or implied, oral or written.
15.Integration. This Amendment, together with the other Loan Documents,
incorporates all negotiations of the parties hereto with respect to the subject
matter hereof and is the final expression and agreement of the parties hereto
with respect to the subject matter hereof.
16.Reaffirmation of Obligations. Each Person comprising the Borrower hereby
(a) acknowledges and reaffirms its obligations owing to the Lender under each
Loan Document to which it is a party, and (b) agrees that each of the Loan
Documents to which it is a party is and shall remain in full force and effect.
Each Person comprising the Borrower hereby (i) further ratifies and reaffirms
the validity and enforceability of all of the Liens and security interests
heretofore granted, pursuant to and in connection with the Security Documents or
any other Loan Document to the Lender as collateral security for the obligations
under the Loan Documents in accordance with their respective terms, and
(ii) acknowledges that all of such Liens and security interests, and all
Collateral heretofore pledged as security for such obligations, continue to be
and remain collateral for such obligations from and after the date hereof
(including, without limitation, from after giving effect to this Amendment).
17.Ratification. Each Person comprising the Borrower hereby restates, ratifies
and reaffirms each and every term and condition set forth in the Credit
Agreement and the Loan Documents effective as of the date hereof and as modified
hereby.
18.Severability. In case any provision in this Amendment shall be invalid,
illegal or unenforceable, such provision shall be severable from the remainder
