order of priority:

 

		(a)	Chargeback to the Extent of Losses. First, Profits shall be allocated to each Member to
the extent of, and in the reverse order of, the aggregate amount of Losses previously allocated to such Member from and after the
Effective Date pursuant to Section 4.2, with respect to which Profits have not been previously allocated pursuant to this
Section 4.1(a).

 

		(b)	Profits. Second, Profits shall be allocated in accordance with the Members' Percentage Interests.

to such Member pursuant to Section 4.1, with respect to which Losses have not been previously allocated pursuant to this
Section 4.2(a).

 

		(b)	Other Losses. Second, except as provided in Section 4.2(d), any remaining Losses
for such Fiscal Year shall be allocated in accordance with Members' Capital Account balances until such Capital Accounts have been
reduced to zero and thereafter in accordance with Section 4.2(c).

 

     

     

    

		(c)	Any Additional Losses. Third, except as provided in Section 4.2(d), any remaining
Losses for such Fiscal Year shall be allocated in accordance with the Members' Percentage Interests.

 

		(d)	Adjusted Capital Account Deficit. An allocation of Losses under Section 4.2(a), Section 4.2(b),
or Section 4.2(c), shall not be made to the extent it would create or increase an Adjusted Capital Account Deficit for any
Member at the end of any Fiscal Year. Any Losses not allocated because of the preceding sentence shall be allocated to the other
Members in proportion to such Members' respective Percentage Interests; provided, however, that to the extent such allocation
would create or increase an Adjusted Capital Account Deficit for another Member at the end of any Fiscal Year, such allocation
shall be made to the remaining Members in proportion to the respective Percentage Interests of such Members.

 

		4.3	Special Allocations. The following special allocations shall be made in the following order:

 

		(a)	Minimum Gain Chargeback. Except as otherwise provided in Regulations Section 1.704-2(f),
notwithstanding any other provision of this Article IV, if there is a net decrease in Company Minimum Gain during any Fiscal
Year, each Member shall be specially allocated items of Company income and gain for such Fiscal Year (and, if necessary, subsequent
Fiscal Years) in an amount equal to the portion of such Member's share of the net decrease in Company Minimum Gain which share
of such net decrease shall be determined in accordance with Regulations Section 1.704-2(g)(2). Allocations pursuant to the previous
sentence shall be made in proportion to the respective amounts required to be allocated to each Member pursuant thereto. The items
to be so allocated shall be determined in accordance with Regulations Section 1.704-2(f)(6) and 1.704-2(j)(2). This Section
4.3(a) is intended to comply with the minimum gain chargeback requirement contained in Regulations Section 1.704-2(f) and shall
be interpreted consistently therewith.

 

		(b)	Member Minimum Gain Chargeback. Except as otherwise provided in Regulation Section 1.704-2(i)(4),
notwithstanding any other provision of this Article IV, if there is a net decrease in Member Nonrecourse Debt Minimum Gain
attributable to a Member Nonrecourse Debt during any Fiscal Year, each Member who has a share of the Member Nonrecourse Debt Minimum
Gain attributable to such Member Nonrecourse Debt (which share shall be determined in accordance with Regulations Section 1.704-2(i)(5))
shall be specially allocated items of Company income and gain for such Fiscal Year (and, if necessary, subsequent Fiscal Years)
in an amount equal to that portion of such Member's share of the net decrease in Member Nonrecourse Debt Minimum Gain attributable
to such Member Nonrecourse Debt, determined in accordance with Regulations Section 1.704-2(i)(4). Allocations pursuant to the previous
sentence shall be made in proportion to the amounts required to be allocated to each Member pursuant thereto. The items to be so
allocated shall be determined in accordance with Regulations Section 1.704-2(i)(4) and 1.704-2(j)(2). This Section 4.3(b)
is intended to comply with the minimum gain chargeback requirement contained in Regulations Section 1.704-2(i)(4) and shall
be interpreted consistently therewith.

 

		(c)	Qualified Income Offset. In the event any Member unexpectedly receives any adjustments,
allocations, or distributions described in Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5), or (6) or any other event creates
an Adjusted Capital Account Deficit, items of Company income and gain shall be specially allocated to each such Member in an amount
and manner sufficient to eliminate the Adjusted Capital Account Deficit of such Member as quickly as possible, provided however,
that an allocation pursuant to this Section 4.3(c) shall be made only if and to the extent that such Member would have an
Adjusted Capital Account Deficit after all other allocations provided for in this Article IV have been tentatively made
as if this Section 4.3(c) were not in the Agreement.

 

     

     

    

		(d)	Nonrecourse Deductions Referable to Liabilities Owed to Non-Members. Any Nonrecourse Deductions
for any Fiscal Year and any other deductions or losses for any Fiscal Year referable to a liability owed by the Company to a Person
other than a Member to the extent that no Member bears the economic risk of loss shall be specially allocated to the Members in
accordance with their Percentage Interests.

 

		(e)	Member Nonrecourse Deductions. Any Member Nonrecourse Deductions for any Fiscal Year shall
be specially allocated to the Member who bears the economic risk of loss with respect to the Member Nonrecourse Debt or other liability
to which such Member Nonrecourse Deductions are attributable in accordance with Regulations Section 1.704-2(i) and Regulations
Section 1.704-1(b).

 

		(f)	Section 754 Adjustments. To the extent an adjustment to the adjusted federal income tax
basis of any Company asset pursuant to Code Section 734(b) or Code Section 743(b) is required, pursuant to Regulations Section
1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to Capital Accounts
shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such
basis) and such gain or loss shall be specially allocated to the Members in accordance with Regulations Section 1.704-1(b)(2)(iv)(m).

 

		4.4	Curative Allocations. The allocations set forth in Section 4.2(d) and Section
4.3 (the "Regulatory Allocations"), are intended to comply with certain requirements of the Regulations. It
is the intent of the Members that, to the extent possible, all Regulatory Allocations shall be offset either with other Regulatory
Allocations or with special allocations of other items of Company income, gain, loss, or deduction pursuant to this Section
4.4. Therefore, notwithstanding any other provision of this Article IV (other than the Regulatory Allocations) the Managers
shall make such offsetting special allocations of Company income, gain, loss, or deduction in whatever manner it determines appropriate
so that, after such offsetting allocations are made, a Member's Capital Account balance is, to the extent possible, equal to the
Capital Account balance such Member would have had if the Regulatory Allocations were not part of this Agreement and all Company
items were allocated pursuant to Section 4.1(a), Section 4.1(b), Section 4.2(a), Section 4.2(b) and
Section 4.2(c). In exercising its discretion under this Section 4.4, the Managers shall take into account any
future Regulatory Allocations under Section 4.3(a) and Section 4.3(b), that although not yet made, are likely
to offset other Regulatory Allocations previously made under Section 4.3(d) and Section 4.3(e).

 

		4.5	Premium Payments and Tax-Exempt Income. Notwithstanding anything in this Agreement to the
contrary: (a) any and all premium payments made by the Company with respect to the Life Insurance Policy shall be allocated solely
to SCC; and (b) upon the death of Mr. Buenting, all tax-exempt income of the Company generated as a result of the Company receiving
the Life Insurance Proceeds shall be allocated to SCC, and to the extent consistent with this Section 4.5, in accordance
with the procedures described in Section 8.6.

 

     

     

    

		4.6	Fees to Members or Affiliates. Notwithstanding the provisions of Section 4.1, in
the event that any fees, interest or other amounts paid to any Member or any Affiliate thereof pursuant to this Agreement or otherwise,
and deducted by the Company in reliance on Code Sections 707(a) and/or 707(c), are disallowed as deductions to the Company on its
federal income tax return and are treated as distributions, then —

 

		(a)	The Profits or Losses, as the case may be, for the Fiscal Year in which such fees, interest, or
other amounts were paid shall be increased or decreased, as the case may be, by the amount of such fees, interest, or other amounts
that are treated as distributions; and

 

		(b)	There shall be allocated to the Member to which or to whom (or to whose Affiliate) such fees, interest,
or other amounts were paid, prior to the allocations pursuant to Section 4.1, an amount of gross income for the Fiscal Year
equal to the amount of such fees, interest, or other amounts that are treated as distributions.

 

	 	4.7	Other Allocation Rules.

 

		(a)	Allocation of Items Included in Profits and Losses. Whenever a proportionate part of the
Profits or Losses is allocated to a Member, every item of income, gain, loss, or deduction entering into the computation of such
Profits or Losses shall be credited or charged, as the case may be, to such Member in the same proportion.

 

		(b)	Allocations in Respect of a Transferred Member's Interest. If any Member's Interest is transferred,
or is increased or decreased by reason of the admission of a new Member or otherwise, during any Fiscal Year of the Company, each
item of income, gain, loss, deduction, or credit of the Company for such Fiscal Year shall be allocated among the Members, as determined
by the Managers, in accordance with any method permitted by Code Section 706(d) and the Regulations promulgated thereunder in order
to take into account the Members' varying interests in the Company during such Fiscal Year.

 

	 	4.8	Tax Allocations.

 

		(a)	Code Section 704(c). The allocations specified in this Agreement shall govern the allocation
of items to the Members for Code Section 704(b) book purposes, and the allocation of items to the Members for tax purposes shall
be in accordance with such book allocations, except that solely for tax purposes and notwithstanding any other provision of this
Article IV:

 

		(i)	In accordance with Code Section 704(c) and the Regulations thereunder, income, gain, loss, and
deduction with respect to any property contributed to the capital of the Company shall be allocated among the Members (including
Members who succeed to the Member's Interest of any other Members or former members of the Company) so as to take account of any
variation between the adjusted federal income tax basis of such property to the Company and its initial Gross Asset Value.

 

		(ii)	In the event the Gross Asset Value of any Company asset is adjusted pursuant to Subparagraph
(b) of the definition of Gross Asset Value in Exhibit A, subsequent allocations of income, gain, loss, and deduction
with respect to such asset shall take account of any variation between the adjusted federal income tax basis of such asset and
its Gross Asset Value in the same manner as under Code Section 704(c) and the Regulations thereunder.

 

     

     

    

		(iii)	The allocations described in Section 4.8(a)(ii) and this Section 4.8(a)(iii) shall
be made using the "traditional method" described in Regulations Section 1.704-3(b).

 

		(b)	Tax Credits. Tax credits, if any, shall be allocated among the Members in proportion to
their Percentage Interests.

 

		(c)	Excess Nonrecourse Liabilities. Solely for purposes of determining a Member's share of the
"excess nonrecourse liabilities" of the Company within the meaning of Regulations Section 1.752-3(a)(3), the Members'
interests in Company profits are in proportion to their Percentage Interests.

 

		4.9	Obligations of Members to Report Consistently. The Members are aware of the income tax consequences
of the allocations specifically set forth in this Article IV and hereby agree to be bound by such allocations in reporting
their shares of Company income and loss for income tax purposes.

 

		4.10	Federal Income Tax. It is the intent of the Company and its Members that the Company will
be governed by the applicable provisions of Subchapter K of Chapter 1 of the Code.

Independent Financial Expert delivers its valuation of the Interests (or such other time or place as the Members may agree). At
such closing, the selling Member shall surrender all original Member Certificates to the buying Member duly executed for Transfer
of the Interests being sold in favor of buying Member or as buying Member may direct. All transfer taxes imposed on the Transfer
shall be payable by the buying Members, and all other closing costs shall be allocated in the manner customarily allocated between

It is understood that SCC has encumbered
certain assets of the Company in order to collateralize a loan agreement (“The Loan”) In the event of a dissolution,
foreclosure or bankruptcy filing of SCC occurring during the period that this loan agreement is in place, Mr. Buenting, or his
assignee, shall have the exclusive right to purchase SCC’s fifty-percent ownership interest in the Company for an amount
equal to the sum of the current loan balance collateralized by the Company’s assets, plus a one-time payment of ten-thousand
dollars ($10,000). However, in no case will Mr. Buenting be required to pay an amount greater than 65% of the then-current Net
Orderly Liquidation Value (“NOLV”) of the specific assets of the Company identified and used as collateral as part
of the Security Agreement between SCC and the lender. It is the intent that all such payments (as mentioned above) made to the
lender by Mr. Buenting will be sufficient to release, in total, all UCC filings on those specific assets, giving Mr. Buenting clear
title to all such Company assets. In the event of an SCC dissolution, foreclosure or bankruptcy after The Loan has been fully paid
with respect to amounts collateralized by the Company’s assets, Mr. Buenting, or his assignee, shall have the exclusive right
to purchase SCC’s fifty-percent ownership interest in the Company for a one-time payment equal to $10,000.

deemed recognized upon such deemed sale shall be allocated in accordance with Article IV; and (iii) the amount of the distribution
shall be considered to be such fair market value of the asset as of the date of dissolution as shall be determined by the Managers.

 

		(e)	The proceeds of sale and all other Company Property of the Company shall be applied and distributed
as follows and in the following order of priority:

 

		(i)	To the expenses of liquidation.

 

		(ii)	To the payment of the debts and liabilities of the Company (including any loans to the Company
from the Members.)

 

     

     

    

		(iii)	To the establishment of any reserves that the liquidator shall determine to be reasonably necessary
for contingent, unliquidated or unforeseen liabilities or obligations of the Company or the Members arising out of, or in connection
with, the Company. Any reserves shall be held by the liquidator or paid over to a bank or title company selected by it to be held
by such bank or title company as escrow holder or liquidator for the purpose of disbursing the reserves to satisfy the liabilities
and obligations described above.

 

		(iv)	The balance (including amounts released from any unnecessary reserves set up pursuant to Section
10.2(e)(iii)), if any, after giving effect to all contributions, distributions and allocations of Profits and Losses for all
periods, to the Members, pro rata in proportion to their positive Capital Account balances.

 

		(f)	Notwithstanding anything to the contrary in this Agreement, upon a liquidation within the meaning
of Section 1.704-1(b)(2)(ii)(g) of the Regulations, if any Member has an Adjusted Capital Account Deficit (after giving effect
to all contributions, distributions, allocations and other Capital Account adjustments for all Fiscal Years, including the year
during which such liquidation occurs) such Member shall have no obligation to make any Capital Contribution, and the negative balance
of such Member's Capital Account shall not be considered a debt owed by such Member to the Company or to any other Person for any
purpose whatsoever.

 

		(g)	Upon completion of the winding up, liquidation and distribution of the assets, the Company shall
be deemed terminated.

 

		(h)	The Managers shall comply with any applicable requirements of applicable law pertaining to the
winding up of the affairs of the Company and the final distribution of its assets.

 

		10.3	Subordination to Creditors. Each Member understands and agrees that by accepting the provisions
of Section 10.2, setting forth the priority of the distribution of assets of the Company to be made upon a liquidation,
such Member expressly waives any right which he, she or it, as a creditor of the Company, might otherwise have to receive distributions
of assets pari passu with the other creditors of the Company in connection with a distribution of assets of the Company
in satisfaction of any liability of the Company, and hereby subordinates to said creditors any such right.

 

		10.4	Return of Contribution; Nonrecourse to Other Members. Except as provided by law or as expressly
provided in this Agreement, upon dissolution, each Member shall look solely to the assets of the Company for the return of his,
her or its Capital Contribution. If the Company Property remaining after the payment or discharge of the debts and liabilities
of the Company is insufficient to return the cash contribution or Capital Account balance of one or more Members, such Members
shall have no recourse against any other Member.

 

		10.5	Offset for Damages. The Company may offset damages for breach of this Agreement by any Member
whose interest is liquidated (either upon the withdrawal of the Member or the liquidation of the Company) against the amount otherwise
distributable to such Member.

		11.1	Exculpation.

 

		(a)	No Covered Person shall be liable to the Company or any other Covered Person for any loss, damage
or claim incurred by reason of any act or omission performed or omitted by such Covered Person in good faith on behalf of the Company
and in a manner reasonably believed to be within the scope of authority conferred on such Covered Person by this Agreement, the
Members, the Managers or an authorized officer or employee of the Company, except that a Covered Person shall be liable for any
such loss, damage or claim incurred by reason of such Covered Person's intentional misconduct, fraud or a knowing violation of
the law, which was material to the cause of action.

 

		(b)	A Covered Person shall be fully protected in relying in good faith upon the records of the Company
and upon such information, opinions, reports or statements presented to the Company by any Person as to matters the Covered Person
reasonably believes are within such other Person's professional or expert competence, including information, opinions, reports
or statements as to the value and amount of the assets, liabilities, profits or losses or any other facts pertinent to the existence
and amount of assets from which distributions to the Members might properly be paid.

 

		11.2	Fiduciary Duty. To the extent that at law or in equity a Covered Person has duties (including
fiduciary duties) and liabilities relating thereto to the Company or to the Members, then, to the fullest extent permitted by applicable
law, a Covered Person acting under this Agreement shall not be liable to the Company or to the Members for its good faith acts
or omissions in reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict
the duties and liabilities of a Covered Person otherwise existing at law or in equity shall replace such other duties and liabilities
of such Covered Person.

 

		11.3	Indemnity. The Company does hereby indemnify and hold harmless any Covered Person to the
fullest extent permitted by the Act.

 

		11.4	Determination of Right to Indemnification. Any indemnification under Section 11.3,
unless ordered by a court or advanced pursuant to Section 11.5, shall be made by the Company only as authorized in the specific
case upon a determination by the Members that indemnification of the Covered Person is proper in the circumstances.

 

		11.5	Advance Payment of Expenses. The expenses of any Member or Managers incurred in defending
a civil or criminal action, suit or proceeding shall be paid by the Company as they are incurred and in advance of the final disposition
of the action, suit or proceeding upon receipt of an undertaking by or on behalf of the Member or the Managers to repay the amount
if it is ultimately determined by a court of competent jurisdiction that the Member or a Manager is not entitled to be indemnified
by the Company. The provisions of this Section 11.5 do not affect any rights to advancement of expenses to which personnel
of the Company other than the Members or the Managers may be entitled under any contract or otherwise by law.

 

		11.6	Assets of the Company. Any indemnification under this Article XI shall be satisfied
solely out of the assets of the Company. No debt shall be incurred by the Company or the Members in order to provide a source of
funds for any indemnity, and the Members shall not have any liability or any liability to make any additional Capital Contribution
on account thereof.

in owners’ prequalification procedures for the Company and guarantee prequalification amounts commensurate with the foregoing
bonding limits.

of SCC or any of its subsidiaries.

Miscellaneous Provisions

 

		12.1	Ownership Certificates. The Company may issue a certificate to each Member to represent
such Member's Interest. Any Manager or officer of the Company may sign such certificate on behalf of the Company. The Company shall
issue a new ownership certificate in place of any previously issued if the record holder of the certificate (a) presents proof
by affidavit, in form and substance satisfactory to the Managers, that a previously issued ownership certificate has been lost,
mutilated, destroyed or stolen and agrees to indemnify the Company for any lost, cost damage or expense arising from the issuance
of a replacement certificate; and (b) if requested by the Managers, delivers to the Company a bond, in form and substance reasonably
satisfactory to the Managers, with such surety or sureties and with fixed or open penalty as the Managers may direct in its reasonable
discretion, to indemnify the Company against any claim that may be made on account of the alleged loss, destruction or theft of
the ownership certificate. If a Member fails to notify the Company within a reasonable time after it has knowledge of the loss,
destruction or theft of such Member's ownership certificate, and a transfer of the Member's Interest represented by that ownership
certificate is registered before receiving such notification, the Company shall have no liability with respect to any claim against
the Company for such transfer or for the issuance of a new ownership certificate consistent with such registration.

 

		12.2	Securities under the UCC. If the Company issues a certificate representing any Member's
Interest, such Member's Interest shall be a "security" as defined in Section 104.8102(1)(n) of the UCC, and this
statement shall constitute an express provision that each such Member's interest is a security governed by Article 8 of the UCC,
within the meaning of Section 104.8103(3) of the UCC, solely for the purposes of establishing the applicability thereto of the
provisions of Article 8 governing securities. Such Member's interest shall not be considered a "security" for any other
purpose, nor shall this statement be construed to suggest that the Member's interest should otherwise be considered a "security."
The Company shall affix on any certificates evidencing a Member's interest a legend in substantially the following form (in addition
to any other legend required by applicable law):

 

     

     

    

The
ownership interest represented by this certificate shall be considered a "security" as defined in Section 104.8102(1)(n)
of the UCC (as defined below) and this statement shall constitute an express provision that the ownership interest evidenced by
this certificate is a security governed by Article 8 of the UCC, within the meaning of Section 104.8103(3) of the UCC, solely
for the purposes of establishing the applicability thereto of the provisions of Article 8 governing securities. The ownership interest
represented by this certificate shall not be considered a "security" for any other purpose. For purposes hereof, "UCC"
shall mean the Uniform Commercial Code as enacted and in effect in the State of Nevada and any other applicable state or jurisdiction.

 

		12.3	Notices. Except as otherwise provided herein, all notices to be given hereunder shall be
in writing and shall be addressed to the Person to receive the notice at his, her or its last known address, facsimile number or
e-mail address appearing on the books of the Company. If no such address, facsimile number or e-mail address has been provided,
it will be sufficient to send any notice to the Person at the Records Office of the Company. For all purposes, notice shall be
deemed given and received, (a) if hand-delivered, when the notice is received; (b) if sent by a nationally or internationally recognized
overnight delivery service, when the notice is received, or (c) if sent during normal business hours by facsimile or e-mail, when
the facsimile or e-mail is transmitted and confirmation of receipt is received by the transmitting party. If any notice is sent
by facsimile or e-mail, the transmitting party shall send by U.S. mail a duplicate copy of the notice to the Person to whom it
was faxed or e-mailed. If notice is tendered and is refused by the intended recipient, the notice shall nonetheless be considered
to have been given and shall be effective as of the date of such refusal. Any notice given in a manner other than that provided
in this Section 12.3 that is received by the intended recipient shall be deemed an effective delivery of the notice. Any
party may, at any time, by giving ten (10) days' prior written notice to any Managers, designate a new address for the giving of
notice to such Person.
	 	 	 
	 	12.4	Insurance. In addition to the Life Insurance Policy and the
Disability Insurance Policy purchased by SCC, the Company may purchase and maintain insurance, to the extent and in such amounts
as the Managers deem reasonable, on behalf of such Persons as the Managers determine, against any liability that may be asserted
against or expenses that may be incurred by any such Person in connection with the activities of the Company.

 

		12.5	Amendments. Any amendment of this Agreement or the Articles of Organization shall be adopted
and effective as an amendment hereto only upon the approval of a Member Majority.

 

		12.6	Applicable Law and Jurisdiction

 

		(a)	The rights and obligations of the parties hereto shall be governed by, and construed in accordance
with, the internal laws of the State of Nevada without giving effect to any choice or conflict of law provision or rule (whether
of the State of Nevada or any other jurisdiction) that would cause the application hereto of the laws of any jurisdiction other
than the State of Nevada. Each Member consents to the jurisdiction of the courts of Washoe County, in the State of Nevada, in the
event any action is brought for declaratory relief or enforcement of any of the terms and provisions of this Agreement.

 

     

     

    

		12.7	Interpretation. The headings in this Agreement are inserted for convenience only and are
not intended to describe, interpret, define, or limit the scope, extent or intent of this Agreement or any provisions contained
herein. With respect to the definitions in Exhibit A, and in the interpretation of this Agreement generally, the singular
may be read as the plural, and vice versa; the neuter gender may be read as the masculine or feminine, and vice versa;
and the future tense may be read as the past or present, and vice versa, all interchangeably as the context may require
in order to fully effectuate the intent of the Members and the transactions contemplated herein. Syntax shall yield to the substance
of the terms and provisions hereof.

 

		12.8	Counterparts. This Agreement may be executed in multiple counterparts, each of which shall
be deemed an original but all of which together shall be deemed to constitute one and the same instrument, and it shall be sufficient
for each party to have executed at least one, but not necessarily the same, counterpart.

 

		12.9	Facsimile and E-mail Copies. Facsimile and e-mailed copies of this Agreement or of any counterpart
and the signatures thereon or on any counterpart, shall have the same force and effect as originals.

 

		12.10	Severability. If any provision of this Agreement, or any application thereof, is held by
a court of competent jurisdiction to be invalid, void, illegal or unenforceable to any extent, that provision or application thereof
shall be deemed severable and the remainder of this Agreement, and all other applications thereof shall not be affected, impaired
or invalidated thereby, and shall continue in full force and effect to the fullest extent permitted by law.

 

		12.11	Waivers. No waiver of any of the provisions of this Agreement shall be deemed, or shall
constitute, a waiver of any other provision, whether or not similar, nor shall any waiver constitute a continuing waiver, and no
waiver shall be binding unless evidenced by an instrument in writing and executed by the party making the waiver.

 

		12.12	No Third Party Beneficiaries. Except as set forth in Article X, this Agreement is
made solely among and for the benefit of the Members and their respective successors and permitted assigns, and no other Person
shall have any rights, interest or claims hereunder or be entitled to any benefits under or on account of this Agreement as a third
party beneficiary or otherwise.

 

12.13     
Representations. Each Member hereby acknowledges and represents as follows:

 

		(a)	The Member has acquired the Member's Interest for investment purposes for such Member's own account
only and not with a view to or for sale in connection with distribution of all or any part of the Member's Interest.

 

		(b)	The Member is aware that this Agreement was drafted by counsel for SCC and that said counsel has
in no way undertaken to represent any other Member. Mr. Buenting acknowledges that said counsel has encouraged him to seek competent
counsel in connection with the negotiation of this Agreement, and that he has had adequate opportunity to do so.

 

     

     

    

		12.14	Securities Law Qualification. To the extent Members' Interests herein constitute securities
under the Securities Act, the sale of such securities has not been registered with the U.S. Securities and Exchange Commission
or registered with or qualified under the securities laws of any state in reliance on one or more exemptions from the registration
requirements. No Transfer of such securities or any interest therein to, or receipt of any consideration therefor, may be made
if the proposed Transfer affects the availability to the Company of such exemptions from registration and qualification, and any
such Transfer must be in compliance with applicable federal and state securities laws. Therefore, Members may not be able to liquidate
their investments and these securities may not be readily accepted as collateral for a loan.

 

		12.15	Terms and Usage Generally. 

 

		(a)	All references herein to articles, sections, exhibits and schedules shall be deemed to be references

		(d)	References to a Person are also to his, her or its successors and permitted assigns.

 

		(e)	Unless otherwise expressly provided herein, any agreement, instrument, statute or regulation defined
or referred to herein or in any agreement or instrument defined or referred to herein means such agreement, instrument, statute
or regulation as from time to time amended, modified or supplemented, including (in the case of agreements or instruments) by waiver
or consent and (in the case of statutes or regulations) by succession of comparable successor statutes or regulations, and references
to all attachments thereto and instruments incorporated therein.

 

		12.16	Complete
Agreement. This Agreement, together with all exhibits and schedules attached hereto and the Articles of Organization constitutes
the complete and exclusive agreement and understanding of the Members with respect to the subject matter contained herein. This
Agreement and the Articles or Organization replace and supersede all prior operating agreements, negotiations, statements, memoranda
and understandings, whether written or oral, by and among the Members or any of them. Effective as of the Effective Date, the
Management Agreement and the Employment Agreement are hereby terminated and are no longer in force or effect.
	 	 	 
	 	12.17 	Dispute Resolution. In the event that SCC and Mr. Buenting
cannot agree on a matter that under this Agreement requires their unanimous consent, the conflict shall be resolved as follows:

 

		(a)	Executive Leadership Team Meeting. Prior to submitting their dispute to non-binding mediation,
SCC and Mr. Buenting, will first present their respective positions to the subsidiary presidents in a meeting of the Executive
Leadership Team (“ELT”) and all in attendance shall render their opinion in an anonymous vote.

 

     

     

    

		(b)	Mediation. Failing to agree on the outcome of the vote by the ELT, SCC and Mr. Buenting
shall attempt to settle the dispute through non-binding mediation. Either party may initiate the mediation process by giving written
notice to the other, and the parties shall, within 30 days thereafter, agree on a mediator and set a mutually acceptable date for
the mediation. The parties shall use a mediator with ADR Services, Inc., or such other mediator upon which the parties may mutually
agree. The parties shall bear equally the cost of the mediator’s fees and expenses, but each party shall pay its own legal
fees and costs associated with the mediation.

 

		(c)	Arbitration. Failing to agree on the outcome of the non-binding mediation, either Party
may submit the matter to binding arbitration by a single arbitrator, in accordance with the then current Rules of Commercial Arbitration
of the American Arbitration Association by serving a written demand for arbitration on the other Party and filing the same with
the American Arbitration Association ("AAA.") The following terms shall apply to any arbitration proceeding commenced
hereunder:

 

		(i)	The arbitration will be held in Carson City, Nevada.

 

		(ii)	The arbitrator in any such proceeding shall have no authority or power (1) to modify or alter any
express condition or provision of this Operating Agreement; (2) to render an award that by its terms has the effect of altering

any Party to the proceeding.

apportioned between the Parties.

 

		(iv)	The Parties agree to be bound by the decision of the arbitrator; the award rendered may be entered
in any court having jurisdiction thereof; and there shall be no appeal therefrom other than for fraud or willful misconduct.

in Section 4 or from seeking provisional equitable remedies, including temporary restraining orders and preliminary injunctions,
from any court of competent jurisdiction in order to protect its rights pending arbitration or in other circumstances where such
relief is deemed necessary, so long as such preliminary relief shall not be sought as a means of avoiding arbitration. Either party
shall pay on demand all reasonable, actual costs and expenses, if any (including, without limitation, counsel fees and expenses)
of the prevailing party in connection with a party’s pursuit of such equitable remedies.

AMENDMENT 1 TO THE FOURTH AMENDED
AND RESTATED OPERATING AGREEMENT

 

 

 

THIS AMENDMENT 1 TO THE FOURTH AMENDED AND RESTATED OPERATING
AGREEMENT (the "Agreement") of Road and Highway Builders, LLC, a Nevada limited liability company (the "Company"
or “RHB”) is made, adopted and entered into as of November 28, 2015 (the "Effective Date") by and
between each of the Members listed on Schedule I of the Agreement and signatory hereto.

 

By this AMENDMENT 1, the Members wish to replace Article 8.8 of
the Agreement in its entirety and replace it with a new Article 8.8 as of the Effective Date of this AMENDMENT 1.

 

THEREFORE, in consideration of the mutual covenants, agreements
and promises made herein, the Members hereby agree to and adopt the following:

 

Article 8.8 shall be eliminated in its entirety and substituted
with the following new Article 8.8:

 

“8.8 SCC Purchase Obligation

 

(a)               
Transfer Upon Sale. In addition to those other Transfers contemplated in Article VIII, upon the acquisition of all
or substantially all of the assets of SCC by a third party, or the sale, merger, consolidation or other business combination of
SCC with or to a third party in which the holders of a majority of the equity interests of SCC before such event no longer hold
a majority of the equity interests of the resulting entity after such event, then SCC shall purchase
from RHB (and RHB shall be required to sell to SCC) the Percentage Interests of RHB (with
such purchase to be made in accordance with the terms of this Article 8.8) 

 

(b)              
Valuation Methodology.

 

(i)                
The purchase price of the Percentage Interests of RHB shall be determined by mutual agreement between SCC and RHB or, if
such Parties cannot agree, by an independent valuation performed by a mutually-selected, nationally recognized investment banking
firm or certified public accounting firm (“Independent Financial Expert A”). Upon completion of its assignment,
Independent Financial Expert A shall notify the Parties in writing of Independent Financial Expert A’s determination of the
value of RHB’s Percentage Interest. Within five business days after receiving written notice by Independent Financial Expert
A, either Party may object to the valuation. Such objecting Party shall evidence their objection by written notice (“Notice
of Objection”) sent to the other Party within the five business day period. If a Party sends such Notice of Objection
to the other Party then, within ten business days of the other Party’s receiving such notice, SCC and RHB shall each designate
a separate, nationally recognized, investment banking firm or certified public accounting firm (“Independent Financial
Experts B and C”). Within 15 business days after being selected, Independent Financial Experts B and C shall mutually-select
a third nationally recognized, investment banking firm or certified public accounting firm (“Independent Financial Expert
D”) that shall prepare a final and binding determination of the value of RHB’s Percentage Interest. The costs of
Independent Financial Experts A, C and D shall be paid for by SCC, and the cost of Independent Financial Expert B shall be paid
for by RHB.

 

     

     

    

(ii)              
Regardless of the determination of value of RHB’s Percentage Interest by any of the methods described in Article 8.8
(b) (i) above, the minimum aggregate value of RHB’s Percentage Interest shall not be less than the greater of one of the
following, pro rata to RHB’s Percentage Interest: (A) five times the average of the Company’s EBITDA for the previous
three fiscal years or (B) five times the Company’s total EBITDA for the trailing twelve months prior to the transaction close
date.

 

(iii)            
Once the value has been determined by one of the methods described in Article 8.8 (b) (i) and (ii) above, any undistributed
net taxable income attributable to RHB’s Percentage Interests must be added to that value to determine the purchase price.
In addition to the purchase price, Richard H. Buenting will be entitled to an Earn-out bonus equal to 50% of the net profits of
all projects listed in the Company’s backlog, plus projects where the company was the apparent low bidder but the project
was not yet listed in backlog, as of the transaction close date. Net profit will be determined based on audited gross margin on
each project minus an allocated overhead charge commensurate with the Company’s annual average overhead percentage of Revenue.
Such net profits will be due and payable only for as long as Richard H. Buenting remains continuously employed by the Company and
only after each listed project is closed out and audited.

 

(c)               
All closings of a Transfer under this Article 8.8 will be held at the RHB’s principal office and shall
take place on the date agreed by RHB and SCC, unless the price and valuation per Percentage Interest is contested, in which case
the closing shall take place at the principal office of RHB at 10:00 am on the tenth business day after the applicable Independent
Financial Expert delivers its valuation of RHB’s Percentage Interests (or such other time or place as the Parties may agree).
All transfer taxes imposed on the Transfer shall be payable by RHB, and all other closing costs shall be allocated in the manner
customarily allocated between buyers and sellers of ownership interests in similar ventures in the State of Nevada.”

 

IN WITNESS WHEREOF, this Amendment 1 has
been executed by the Parties hereto as of the Effective Date.
