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)

| | (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.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (e) | Member Nonrecourse Deductions. Any Member Nonrecourse Deductions for any Fiscal Year shall

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).

4.3 (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).
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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

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,

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.

| | 8.9 | Buenting Purchase Option
| | --- | ------------------------



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.

the Company shall not be commingled with the funds of any other Person, and the Managers shall not employ, or permit any other
Person to employ, such funds in any manner except for the benefit of the Company. If the Managers unanimously agree, SCC will
be allowed to sweep the cash generated by the Company. In exchange, SCC shall pay interest to the Company on the amount of cash
swept. The interest rate shall be the Prime Rate, as published in the Wall Street Journal, plus 2%. Interest payments on swept
cash shall be payable monthly to the Company until the net cash swept equals zero. All cash swept shall be secured by First Deeds
of Trust on property owned by SCC, or other wholly owned subsidiaries. If the amount of cash swept exceeds the value of the property
owned by SCC, the Company may require additional collateral above the Deeds of Trust to be provided by SCC, with SCC allowing
a second collateralized position on SCC’s owned and leveraged equipment.

is defined in Section 6231 of the Code) to represent the Company in connection with all tax examinations and proceedings and to
oversee the Company's tax affairs in the best interests of the Company. The Members agree to cooperate with the Tax Matters Partner
and to do or refrain from doing any or all things reasonably required by the Tax Matters Partner in connection with any such examinations
or proceedings. The Managers may from time to time designate any other Member or officer thereof to serve as Tax Matters Partner.
As of the Effective Date, the Tax Matters Partner shall be SCC.

kind based upon the fair market value as of the date of such distribution.
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Any Profits or Losses realized by the Company upon the sale of the Company Property shall be recognized
and allocated to the Members in the manner set forth in Article IV. To the extent an asset is to be distributed in kind,
(i) the asset shall be deemed to have been sold at its fair market value on the date of distribution; (ii) the Profits or Losses

| | (iii) | To the establishment of any reserves that the liquidator shall determine to be reasonably necessary

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

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

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

| | --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 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.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

distributable to such Member.

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

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.

to any other legend required by applicable law):

| | 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.

| | (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.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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.

12.13Representations. 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.

| | 12.17 | 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
or modifying any express condition or provision of this Agreement; or (3) to award punitive or exemplary damages for or against
any Party to the proceeding.
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | The arbitrator shall determine the manner in which the costs of the arbitration proceeding are
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.
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (d) | Equitable Remedies.
Nothing in this Agreement shall be construed to preclude either Party from seeking the remedy of specific performance provided
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.
