	$	1,500,000.00	  	September 22, 2008

 FOR VALUE RECEIVED, the undersigned, PLATINUM RESEARCH ORGANIZATION, INC., a Delaware
corporation (“PRO”), PRO OPERATIONS, L.P., a Texas limited partnership (“PRO LP”), and PLATINUM INTELLECTUAL PROPERTY, L.P., a Texas limited partnership (“PIP LP”) (collectively on a
joint and several basis, the “Borrower”), hereby makes this promissory note (this “Note”) and promises to pay to the order of ALPINA LENDING, L.P., a Nevada limited partnership (“Alpina” or
the “Agent”), on its own behalf and as agent for those persons listed on Schedule 1 attached hereto (collectively, the “Lenders”), the principal sum of One Million Five Hundred Thousand and No/100 Dollars
($1,500,000.00) or, if greater or less, the aggregate principal amount of all advances made to Borrower by the Agent on behalf of the Lenders, as shown on Schedule 2 attached hereto (as the same is modified from time to time by Agent),
together with interest on the unpaid balance thereof at the rate hereinafter provided, both principal and interest payable as hereinafter provided in lawful money of the United States of America, at the address of Agent as set forth in this Note, or
at such other place as from time to time may be designated by the holder of this Note. 
 It is hereby acknowledged that (a) the Agent,
The Fairmount Company, R.T. Vanderbilt, Steven Kidwell and Melinda J. Bickers are each Lenders under this Note, (b) the Lenders have appointed the Agent as their administrative agent, pursuant to that certain Agency Agreement and Assignment of
Participation Interest in Platinum Research Organization, Inc. and Platinum Intellectual Property, L.P. Note (the “Agency Agreement”) dated the date of this Note, (c) the Lenders have given the Agent their authority and
permission to enter into this Note and the other Loan Documents on their behalf, and (d) the Lenders have authorized and instructed the Agent to lend such funds as may be borrowed by Borrower pursuant to this Note, subject to the terms and
conditions of this Note and the Agency Agreement. 
 Lenders have previously advanced $192,775 (the “Bridge Loan”) to
Borrower prior to the date of this Note. The Bridge Loan, and all accrued but unpaid interest thereon, shall be deemed principal outstanding under this Note. The Initial Advance shall be offset by an amount equal to the Bridge Loan. 
 Unless otherwise defined herein, capitalized terms used in this Note shall have the meanings given to such terms in the Schedule of Definitions attached
hereto as Schedule 3. 

 1. Commitment Fee; Advances. 
 (a) Advances. Concurrently with the execution of this Note and assuming all conditions precedent have been met as set forth in
Section 11, the Agent shall advance on behalf of the Lenders the principal sum of Seven Hundred Fifty Thousand and No/100 Dollars ($750,000.00) (the “Initial Advance”), less the amount of the Bridge Loan. In addition to the
Initial Advance, upon the terms and conditions set forth herein, Borrower may borrow an additional Seven Hundred Fifty Thousand and No/100 Dollars ($750,000.00) (the “Second Traunche” and together with the Initial Advance, the
“Commitment”) under this Note. This Note is not a revolver and thus, Borrower may not borrow, repay, and reborrow the principal of this Note. 
 (b) Agent and Lenders Commitment. Provided that the terms and conditions of this Note have been met on and as of the date of this
Note and on and as of the date of each future advance, if any, Agent on behalf of the Lenders has committed to advance, in the aggregate, up to One Million Five Hundred Thousand and No/100 Dollars ($1,500,000.00) in principal to Borrower hereunder.
No advance(s) shall be made which cause the aggregate outstanding principal balance of this Note to exceed One Million Five Hundred Thousand Dollars ($1,500,000.00). 
 (c) Procedure for Second Traunche. Borrower shall request an advance for the Second Traunche under this Note by providing the Agent
with a written request for such advance, by no later than 10:00 a.m. Dallas, Texas time, three (3) business days prior to the date the advance is requested, executed by the Chief Executive Officer of Borrower. Borrower’s notice shall
(i) state that Borrower has successfully run and passed an industry IVA sequence engine test, and (ii) be accompanied by a certificate executed by the Chief Executive Officer of Borrower in which the Chief Executive Officer certifies that
all representations and warranties contained in this Note and the other Loan Documents are, and will be as of the date of the requested advance of the Second Traunche, true and correct in all respects, and further certifying that Borrower is, and
will be as of the date of the requested advance, in compliance with all covenants, conditions and agreements in this Note and the other Loan Documents. The Agent shall approve Borrower’s request and advance the Second Traunche within three
(3) business days of the Agent’s receipt of Borrower’s notice so long as (i) following the advance of the Second Traunche, no more than $1,500,000 in principal has been advanced under this Note, (ii) no Event of Default has
occurred under this Note, and (iii) no “default” or “event of default” has occurred under any Loan Document which defines either such term with respect to the Borrower, and the same is not remedied within the applicable
period of grace (if any) provided in such Loan Document. 
 (d) Escrow. Borrower acknowledges that Agent may make any
and all advances through an escrow agent to its choosing and a related escrow account.

 2. Payment of Principal and Interest. 
 (a) Maturity Date. Subject to any rights of acceleration provided in this Note and any other Loan Document, the principal amount of
this Note, together with all accrued and unpaid interest thereon, shall be due and payable on February 11, 2011 (as may be extended pursuant to the terms of this Note, the “Maturity Date”). 
 (b) Payment of Interest. Interest on the unpaid principal balance of this Note shall accrue on a monthly basis, compound on an
annual basis and shall be due and payable in a single installment on the Maturity Date, on which date all unpaid principal and accrued interest on this Note shall be due and payable. 
 (c) Optional Prepayment. Provided any payments then due under this Note have been paid (principal, interest, or otherwise), the
unpaid principal amount of, and any accrued but unpaid interest on, this Note may be prepaid in whole or in part, from time to time prior to the Maturity Date, upon no less than 14 days’ prior written notice to Agent which states the amount of
the intended prepayment, which amount shall be $25,000 or a higher multiple thereof; provided, however, that Agent shall be entitled to convert all or part of the amount of such noticed prepayment to Common Stock in Borrower, by giving
notice to Borrower of its intent to convert in accordance with Section 4 hereof during the 14 day notice period. 
 (d)
Payments. All payments due on this Note shall be payable in lawful money of the United States of America, at the principal office of the Agent at 7161 S. Eastern Ave., Suite 3A, Las Vegas, Nevada 89119-4675, by no later than 2:00 p.m., Las
Vegas, Nevada time, on the date such payment is due. If any payment due under this Note is scheduled or otherwise would be due on a Saturday or Sunday, or on a holiday recognized and observed by banks in Las Vegas, Nevada, then Borrower shall have
until the next business day to make such payment. All payments shall be made by cashier’s or certified check or wire transfer of immediately available funds. 
 (e) Application of Payments. Unless otherwise agreed to in writing or otherwise required by applicable law, payments will be
applied first to unpaid accrued interest, then to principal, and any remaining amount to any unpaid collection costs and other charges; provided, however, that upon delinquency of payment or other Event of Default under this Note,
Agent reserves the right to apply payments among principal, interest, collection costs and other charges, at its discretion. 
 3.
Interest Rate and Computation. 
 (a) Interest Rate. This Note will bear interest at the rate equal to the
variable “prime rate” from time to time published in the Money Rates column of The Wall Street Journal plus three percent (3%) per annum, accrued monthly and compounded annually. Under no circumstances shall this Note at
any point in time accrue interest at a rate in excess of the Maximum Rate (as defined below). 
  

 3 

 (b) Default Rate. Following the occurrence and during the continuation of
(i) the failure of the Borrower to pay in full on the date due, in such manner as is provided in this Note, any payment obligations hereunder, or (ii) the occurrence of an Event of Default under this Note, or (iii) a
“default” or “event of default” occurs under any other Loan Document which defines either such term, the principal balance of this Note which is thus delinquent (which may be the entire principal balance of this Note in
circumstances where this Note is mature or has been accelerated due to an Event of Default under this Note or a “default” or “event of default” under any other Loan Document or for another reason) shall bear interest at the
Maximum Rate, automatically and without the necessity of notice, until such delinquent amount is paid or such breach or default is otherwise cured to the satisfaction of Agent. As used in this Note, the term “Maximum Rate” shall
mean the lesser of (i) eighteen percent (18%), or (ii) the maximum lawful rate of interest which may be contracted for, charged, taken, received or reserved by the Agent in accordance with the applicable laws of the State of Nevada (or
applicable United States federal law to the extent that it permits the Agent to contract for, charge, take, receive or reserve a greater amount of interest than under Nevada law), taking into account all fees and charges, if any, contracted for,
charged, received, taken or reserved by the Agent in connection with the transaction relating to this Note and the Indebtedness evidenced by this Note and other Loan Documents which are treated as interest under applicable law made in connection
with the loan evidenced by this Note and the other Loan Documents. 
 4. Conversion. 
 (a) Conversion Right. At any time starting six months after the date of this Note and ending on the date that the full and final
payment of all amounts due under this Note is paid, in the sole discretion of the Agent, the Agent may convert all or part of the outstanding principal balance of this Note, and all or part of any accrued but unpaid interest thereon, into Common
Stock, par value $.001 per share (the “Common Stock”), of PRO. Agent may convert outstanding Note principal only, accrued and unpaid interest only, or both outstanding principal and accrued but unpaid interest in any combination
desired by Agent, in its discretion. The conversion price with respect to this Note is $0.18 for one (1) share of Common Stock, subject to adjustment in accordance with the terms of Section 5 hereof (the “Conversion
Price”). Accordingly, if the Agent decided to convert $500,000 in Note principal (without interest) to Common Stock and none of the events named in Section 5 requiring an adjustment had occurred, then upon conversion of $500,000 in
Note principal, Lenders would receive an aggregate of Two Million Seven Hundred Seventy Seven Thousand Seven Hundred Seventy Eight (2,777,778) shares of Common Stock in PRO, and the outstanding principal balance would automatically be reduced
by $500,000. 
  

 4 

 (b) Exercise of Conversion
Right. To exercise its conversion rights from time to time, the Agent shall give PRO written notice of its intent to convert this Note in whole, or the portion specified in the notice. The notice shall also state the name or names of the Lenders
(or their respective designees) to which shares of Common Stock should be issued and the number of shares of Common Stock which should be issued to each such Lender (or such Lender’s designee). Closing of the conversion shall occur no later
than the seventh (7th) day following the date of the Agent’s written notice at the Agent’s office, or at such other place as agreed
to by the Agent. At the closing of the conversion, Lenders shall be deemed automatically admitted as shareholders of PRO with respect to the Common Stock being received on conversion without any further action on Agent’s or Lenders’ or
PRO’s part and PRO shall deliver to Agent certificate(s) representing the number of shares Common Stock acquired by Lenders, and the dollar amount of the Note which was converted shall be deemed a payment on the Note in such amount. Each
conversion shall be deemed to have been effected on the date of the notice of the conversion, and the Common Stock into which the portion of the Note was converted shall be deemed issued as of such date. 
 (c) Qualified Public Offering. Immediately prior to PRO’s sale of its Common Stock in a firm commitment underwritten public
offering pursuant to a registration statement under the Securities Act of 1933, as amended, covering the offer and sale of Common Stock for the account of Borrower in which the net proceeds of Borrower are equal to or greater than Ten Million and
No/100 Dollars ($10,000,000.00) (before deduction of underwriters’ commissions and expenses) (“Qualified Public Offering”), the Agent, in its sole discretion, may convert all or part of the outstanding principal balance of this
Note, and all or part of any accrued but unpaid interest thereon, into Common Stock of PRO in connection with such Qualified Public Offering. 
 (d) Registration Rights. Should Agent exercise its conversion rights pursuant to this Section 4, the Company agrees to enter into a registration rights agreement with Agent and/or the applicable Lender(s)
on commercially reasonable terms, which shall include, without limitation, piggyback registration rights and other provisions that are reasonable and customary for registration rights agreements generally. 
 5. Anti-Dilution Provisions. The Conversion Price shall be subject to adjustment from time to time upon the happening of any of the following
events: 
 (a) Adjustment for Stock Splits and Combinations. If PRO shall at any time or from time to time after the
date of this Note effect a subdivision of its outstanding Common Stock, the Conversion Price in effect immediately before that subdivision shall be proportionately decreased so that the number of shares of Common Stock issuable on conversion of all
or any portion of the Note shall be increased in proportion to such increase in the aggregate number of shares of Common Stock outstanding. If PRO shall at any time or from time to time after the date of this Note combine the outstanding shares of
Common Stock, the Conversion Price in effect immediately before the combination shall be proportionately increased so that the number of shares of Common Stock issuable on conversion of all or any portion of the Note shall be decreased in proportion
to such decrease in the aggregate number of shares of Common Stock outstanding. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective. 
  

 5 

 (b) Adjustment for Certain Dividends and Distributions. In the event PRO at any
time or from time to time after the date of this Note shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable on the Common Stock in additional shares
of Common Stock, then and in each such event the Conversion Price in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on
such record date, by multiplying the Conversion Price then in effect by a fraction: (i) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the
close of business on such record date, and (ii) the denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus
the number of shares of Common Stock issuable in payment of such dividend or distribution. Notwithstanding the foregoing, if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the
date fixed therefor, the Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter the Conversion Price shall be adjusted pursuant to this subsection as of the time of actual payment of such
dividends or distributions. 
 (c) Adjustments for Other Dividends and Distributions. In the event PRO at any time or
from time to time after the date of this Note shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of PRO (other than a distribution of
shares of Common Stock in respect of outstanding shares of Common Stock) or in other property, then and in each such event provision shall be made so that Agent shall receive upon conversion of all or any portion of the Note, in addition to the
number of shares of Common Stock receivable thereupon, the kind and amount of securities of PRO, cash or other property which they would have been entitled to receive had the Note been converted into Common Stock on the date of such event and had
Agent thereafter, during the period from the date of such event to and including the conversion date, retained such securities receivable by it as aforesaid during such period, giving application to all adjustments called for during such period
under this paragraph. 
 (d) Issuances. If after the date of this Note and until the Note is paid or has been converted
in its entirety, PRO issues to any investor or other Person other than Lenders, Common Stock or other equity securities of PRO, or any rights convertible into or options to purchase Common Stock or other equity securities of PRO (the “New
Issuance”), for a price per share which is less than the Conversion Price then in effect (the initial Conversion Price being $0.18) (the “Dilutive Price”), then the Conversion Price shall be multiplied by a fraction, of
which the denominator shall be the number of shares of Common Stock outstanding on the date of the New Issuance plus the number of additional shares of Common Stock issued or offered for subscription or purchase in the 

  

 6 

 
New Issuance, and of which the numerator shall be the number of shares of Common Stock outstanding on the date of such New Issuance plus the number of shares
which the aggregate offering price of the total number of shares so offered (assuming receipt by PRO in full of all consideration payable in connection with such New Issuance) would purchase at the Dilutive Price. Notwithstanding the foregoing or
any other provision herein to the contrary, no adjustment to the Conversion Price will be required as a result of any issuance by PRO of any Common Stock, any other class of capital stock, or any other securities, options, rights, or warrants with
respect thereto (A) pursuant to any stock option plan, restricted stock plan or other compensatory plan or arrangement with any officer, director, employee or consultant of PRO or any affiliated entity, (B) pursuant to or in connection
with any agreement or understanding in effect on or before the date hereof, (C) pursuant to or in connection with any merger, consolidation, statutory share exchange, self tender offer for all or substantially all Common Stock, sale of all or
substantially all of PRO’s assets or recapitalization of the Common Stock of PRO, or (D) to any vendor, customer or other person or entity with which PRO has or is attempting to develop a business relationship. 
 (e) Merger or Consolidation. In case of any merger or consolidation of PRO with any corporation or other entity, other than a
consolidation or merger in which PRO is the surviving entity and which does not result in any reclassification or change of the outstanding Common Stock or Distributed Securities, this Note shall be automatically adjusted to represent the right to
purchase at the Conversion Price the number of shares of Common Stock or other securities or assets that the Agent, on behalf of the Lenders, would have been entitled to receive if the Agent had converted this Note on behalf of the Lenders on or
prior to the effective date of such merger or consolidation. 
 (f) Calculations. No adjustment in the Conversion Price
shall be required unless such adjustment would require a cumulative increase or decrease of at least $0.05 in such price; provided, however, that any adjustments that by reason of this subparagraph (d) are not required to be made shall be
carried forward and taken into account in any subsequent adjustment until made. Notwithstanding any other provisions of this Section 5, PRO shall not be required to make any adjustment of the Conversion Price for the issuance of any Common
Stock pursuant to any plan providing for the reinvestment of dividends or interest payable on securities of PRO and the investment of additional optional amounts in Common Stock under such plan. All calculations under this Section 5 shall be
made to the nearest cent (with $.005 being rounded upward) or to the nearest one-tenth of a share (with .05 of a share being rounded upward), as the case may be. 
 (g) Certificates as to Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price pursuant to this
Section 5, PRO at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and furnish to Agent a certificate
setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property into which the Note is convertible) and 

  

 7 

 
showing in detail the facts upon which such adjustment or readjustment is based. PRO shall, as promptly as reasonably practicable after the written request
at any time of Agent (but in any event not later than 10 days thereafter), furnish or cause to be furnished to such holder a certificate setting forth (i) the Conversion Price then in effect, and (ii) the number of shares of Common Stock
and the amount, if any, of other securities, cash or property which then would be received upon the conversion of the Note. 
 6.
Default. Each of the following events shall constitute an Event of Default under this Note (for purposes of clarity, the term “Borrower” shall mean any of PIP LP, PRO LP or PRO): 
 (a) The failure of the Borrower to pay, on or prior to the date due, any payments due under this Note (principal, interest, or otherwise),
without the requirement of or benefit of any further notice or grace periods of any kind; or 
 (b) Any “default” or
“event of default” occurs under any other Loan Document which defines either such term with respect to the Borrower, and the same is not remedied within the applicable period of grace (if any) provided in such Loan Document; or

shall be no remedy period for the covenants contained in Section 10(a)(vii) or Section 10(b); or 
 (d) Any
representation or warranty made by Borrower in any Loan Document shall prove to have been false or incorrect in any material respect on any date on or as of when made, or any Loan Document at any time ceases to be valid, binding and enforceable for
any reason other than its release or subordination by Lender; or 
 (e) the entry of a decree or order for relief by a court
having jurisdiction in respect of Borrower in an involuntary case under the federal bankruptcy laws, as now or hereafter constituted, or any other applicable federal or state bankruptcy, insolvency or other similar law, or appointing a receiver,
liquidator, assignee, custodian, trustee, sequestrator (or similar official) of Borrower or for any substantial part of its property, or ordering the winding up or liquidation of its affairs; or 
 (f) the commencement by Borrower of a voluntary case under the federal bankruptcy laws, as now constituted or hereafter amended, or any
other applicable federal or state bankruptcy, insolvency or other similar law, or the consent by it to the appointment to or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of

 (m) any “default” or “event of
default” shall occur under any credit agreement, loan agreement, promissory note, or other document evidencing indebtedness for borrowed money incurred by the Borrower, or any subordination agreement, security agreement, pledge agreement, deed
of trust, or other security documents executed by Borrower in connection therewith (“default” and “event of default” having the meaning given to such terms in any of the agreements described above), including, without limitation,
the indebtedness with the City of Seattle Retirement System (the “SCERS Debt”); or 
 (n) the failure of PRO
LP to deliver on or before October 31, 2008 a certificate (or certificates) of the good standing (including tax good standing) of PRO LP in the State of Texas issued by the appropriate authorities of such jurisdiction. 
 7. Remedies upon Default. 
 (a) Upon the occurrence of an Event of Default, the Agent may (i) cause all of the principal and accrued but unpaid interest under this Note to become immediately due and payable without notice or demand or declaration of any kind,
(ii) pursue such other rights or remedies (legal or equitable) against Borrower as the Agent on behalf of the Lenders may have under this Note, any other Loan Document or otherwise, or (iii) request Borrower to cause all payments due under
the Note (principal, interest, and otherwise) to be converted into shares of Common Stock of Borrower in accordance with Section 4 hereof (Borrower shall comply with such conversion request within three (3) days after receiving notice of
the request from the Agent). 
  

 9 

 (b) Borrower and all other parties now or hereafter liable for payment hereof, whether as
endorser, guarantor, surety or otherwise, severally waive presentment, demand, grace, diligence in collecting, protest and notice of every kind as to this Note and as to each, every and all payments due hereunder. 
 (c) If any Default shall occur and be continuing, Agent may protect and enforce its rights and the rights of Lenders under the Loan
Documents by any appropriate proceedings, including proceedings for specific performance of any covenant or agreement contained in any Loan Document, and Agent may enforce the payment of any Obligations due it or enforce any other legal or equitable
right which it may have. All rights, remedies and powers conferred upon Agent on behalf of Lenders under the Loan Documents shall be deemed cumulative and not exclusive of any other rights, remedies or powers available under the Loan Documents or at
law or in equity. 
 (d) If any Default shall occur and be continuing under Section 6(m), Agent shall have the right, but
not the obligation, to cure any such “default” or “event of default”, and any costs incurred in connection with such actions shall be added as principal under this Note. 
 8. Representations and Warranties of Borrower. Borrower hereby represents and warrants to Agent and Lenders, on a joint and several basis
to the extent there is more than one Borrower, which representations and warranties shall survive until the date on which the outstanding principal balance of this Note and all interest thereon shall be repaid or converted in full and all
Obligations of Borrower under this Note and any other Loan Document have been discharged, that the following are true and correct as of the Closing Date: 
 (a) Organization. PRO is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware. PIP LP is a partnership duly organized, validly existing and in good

PIP LP and their respective general partners are the only subsidiaries of PRO. PIP LP is the only subsidiary of PRO LP. PIP LP has no subsidiaries. 
 (b) Authorization. Borrower has all requisite power to execute and deliver this Note, to perform its Obligations hereunder, and to consummate the transactions contemplated hereby. The execution, delivery and

Document will be, when executed and delivered, legal, valid and binding agreements of Borrower, enforceable against it in accordance with their respective terms. No other proceedings on the part of Borrower are necessary to authorize the execution
and delivery by Borrower of this Note and the other Loan Documents, the performance by Borrower of its Obligations under this Note and the other Loan Documents, and the consummation by Borrower of the transactions contemplated hereby and thereby.

  

 10 

 (c) No Violations. Borrower is not in violation or default of any provision of its
organizational documents, as amended. Each Borrower’s organizational documents, as certified by the appropriate governmental authority or respective officer of such Borrower, have been provided to Agent on or prior to the Closing Date. Borrower
is in compliance with all applicable federal, state and local statutes, laws and regulations, except those that would not have a Material Adverse Effect. Other than as disclosed in Section 8(c) of the Disclosure Schedule, Borrower has not
breached or defaulted under, nor does Borrower have any knowledge of any claim or threat that Borrower has breached or defaulted under, any term or condition of any agreement, contract, lease, license, instrument or commitment to which Borrower is a

Senior Debt) shall be subordinated to the Indebtedness created by this Note and the other Loan Documents, as evidenced by a written subordination or intercreditor agreement among Borrower and the holder of such additional Indebtedness, and, if

 15 

 (v) create, incur, assume or suffer to exist, any Liens other than Permitted Liens; or

 (vi) engage in any transaction obligating Borrower with any of its Affiliates where any material term of the transaction is

appropriate officials in any states in which the character of the properties owned or held by PIP LP, PRO LP or PRO (as the case may be) or the nature of the business transacted by them makes such qualification necessary, except to the extent such

 Any change in the address of any party hereunder shall not be effective as to the other party unless notice of
such change of address is sent to the other party in accordance with the foregoing. 
 17. Amendments and Waivers. Any provision of
this Note may be amended, supplemented, waived, discharged or terminated only by a written instrument signed by Borrower and the Agent. 
 18. Delays and Omissions. No delay or omission of Agent or any other holder hereof to exercise any power, right or remedy accruing to Agent or any other holder hereof shall impair any such power, right or remedy or shall be construed
to be a waiver of the right to exercise any such power, right or remedy. 
 19. Binding Effect. This Note and all the covenants and
agreements contained herein shall be binding upon, and shall inure to the benefit of, the respective legal representatives, heirs, successors and permitted assigns of Borrower and Agent; provided that Borrower may not assign or transfer this Note
without the prior written consent of Agent. 
  

 19 

 20. Headings; Pronouns. All pronouns and any variations thereof shall be deemed to refer to the
masculine, feminine, neuter, singular or plural, as the identity of the entities or persons referred may require. The headings of the sections of this Note are inserted for convenience only and shall not constitute a part hereof nor affect in any
way the meaning or interpretation of this Note. “Herein,” “hereof” and “hereunder” and other words of similar import refer to this Note as a whole and not to any particular section or other subdivision. All references
herein to any action(s) which are to be taken (or which are prohibited from being taken) by any Person or the Borrower shall apply to such Person or the Borrower, as the case may be, whether such action is taken directly or indirectly. All
references herein to actions by the Borrower (including, without limitation, actions denoted by terms such as “create,” “sell,” “transfer” or “dispose of”) mean such action whether voluntary or involuntary, by
operation of law or otherwise. 
 21. Severability. If any provision of this Note is held to be illegal, invalid or unenforceable
under present or future laws, the legality, validity and enforceability of the remaining provisions of this Note shall not be affected thereby, and this Note shall be liberally construed so as to carry out the intent of the parties to it.

 22. Usury. All agreements between Borrower and the Agent or other holder of this Note, whether now existing or hereafter arising
and whether written or oral, are expressly limited so that in no contingency or event whatsoever, whether by acceleration of the maturity of this Note or otherwise, shall the amount paid, or agreed to be paid, to the holder hereof for the use,
forbearance or detention of the money to be loaned hereunder or otherwise, exceed the maximum amount permissible under applicable Law. If from any circumstances whatsoever fulfillment of any provision of this Note or of any other document
evidencing, securing or pertaining to the Indebtedness evidenced hereby, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by applicable Law, then, ipso facto, the obligation to be
fulfilled shall be reduced to the limit of such validity, and if from any such circumstances the holder of this Note shall ever receive as interest under this Note or any other document evidencing, securing or pertaining to the Indebtedness
evidenced hereby or otherwise an amount that would exceed the highest lawful rate, such amount that would be excessive interest shall be applied to the reduction of the principal amount owing under this Note or on account of any other Indebtedness
of Borrower to the holder hereof relating to this Note, and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal of this Note and such other Indebtedness, such excess shall be refunded to Borrower. In
determining whether or not the interest paid or payable with respect to any Indebtedness of Borrower to the holder hereof, under any specific contingency, exceeds the highest lawful rate, Borrower and the holder hereof shall, to the maximum extent
permitted by applicable Law, (a) characterize any non-principal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, (c) amortize, prorate, allocate and spread the
total amount of interest throughout the full term of such Indebtedness so that the actual rate of interest on account of such Indebtedness is uniform throughout the term thereof, and/or (d) allocate interest between portions of such
Indebtedness, to the end that no such portion shall bear interest at a rate greater than that permitted by applicable Law. The terms and provisions of this paragraph shall control and supersede every other conflicting provision of all agreements
between Borrower and Agent or other holder hereof. As used in this Section 22, the term 

  

 20 

 
“applicable Law” means the laws of the State of Nevada or the laws of the United States of America, whichever laws allow the greater
interest, as such laws now exist or may be changed or amended or come into effect in the future. 
 23. Acknowledgments and
Admissions. Agent on behalf of Lenders and Borrower intend to contract in strict compliance with applicable usury Law from time to time in effect. Borrower shall not, nor shall any present or future guarantors, endorsers, or other persons
hereafter becoming liable for payment of any Obligation hereunder, ever be liable for unearned interest thereon, nor shall Borrower or such other persons ever be required to pay interest thereon in excess of the maximum amount that may lawfully be
charged under applicable Law from time to time in effect, and the provisions of this Section 23 shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. Agent on behalf of Lenders
expressly disavows any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of this Note is accelerated. Borrower hereby represents, warrants, acknowledges and admits that (a) it has been
advised by counsel in the negotiation, execution and delivery of the Loan Documents to which it is a party, (b) it has made an independent decision to enter into this Note and the other Loan Documents to which it is a party, without reliance on
any representation, warranty, covenant or undertaking by Agent, whether written, oral or implicit, other than as expressly set out in this Note or in another Loan Document delivered on or after the date hereof, (c) there are no representations,
warranties, covenants, undertakings or agreements by Agent as to the Loan Documents except as expressly set out in this Note or in another Loan Document delivered on or after the date hereof, (d) Agent has no fiduciary obligation toward
Borrower with respect to any Loan Document or the transactions contemplated thereby, (e) the relationship pursuant to the Loan Documents between Borrower, on one hand, and Agent on behalf of Lenders, on the other hand, is and shall be solely
that of debtor and creditor, respectively, (f) no partnership or joint venture exists with respect to the Loan Documents between Borrower and Agent or Lenders, (g) should an Event of Default or Default occur or exist, Agent will determine
in its sole discretion and for its own reasons what remedies and actions it will or will not exercise or take at that time, (h) without limiting any of the foregoing, Borrower is not relying upon any representation or covenant by Agent, or any
representative thereof, and no such representation or covenant has been made, that Agent will, at the time of an Event of Default or Default, or at any other time, waive, negotiate, discuss, or take or refrain from taking any action permitted under
the Loan Documents with respect to any such Event of Default or Default or any other provision of the Loan Documents, and (i) Agent has relied upon the truthfulness of the acknowledgments in this Section 23 in deciding to execute and enter
into this Note and to become obligated hereunder. 
 24. Counterparts. This Note may be executed in any number of counterparts, each
of which shall be deemed to be an original, but all of which together shall constitute one Note. 
 25. Choice of Law;
Jurisdiction; Waiver. THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS, OTHER THAN CHOICE OF LAW RULES, OF THE STATE OF TEXAS. THE FEDERAL AND STATE COURTS OF COMPETENT JURISDICTION LOCATED IN DALLAS COUNTY, TEXAS,
SHALL HAVE PERSONAL JURISDICTION OVER THE PARTIES TO THIS 

  

 21 

 
NOTE, AND NO ACTION TO INTERPRET OR ENFORCE THIS NOTE SHALL BE INSTITUTED IN ANY OTHER JURISDICTION. EACH PARTY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS NOTE BEING BROUGHT IN THE FEDERAL OR STATE COURTS OF COMPETENT JURISDICTION LOCATED IN DALLAS COUNTY,
TEXAS, AND HEREBY FURTHER IRREVOCABLY WAIVES ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN ANY SUCH COURT HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. NOTWITHSTANDING THE FOREGOING, TO THE EXTENT OTHERWISE PERMITTED BY LAW, ANY CLAIMS
UNDER THIS NOTE THAT PERTAIN TO USURY SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEVADA. 
 THIS NOTE AND ALL OTHER DOCUMENTS
EXECUTED BY ANY OF THE PARTIES SUBSTANTIALLY CONCURRENTLY HEREWITH TOGETHER CONSTITUTE A WRITTEN LOAN AGREEMENT WHICH REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT
ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

and restated to read in its entirety as follows: 
 “Section 8.01 Participation Payment. As additional
consideration and inducement for the Purchaser to purchase the Note from the Company hereunder, the Company agrees that it shall pay to the Purchaser quarterly participation payments (the “Quarterly Participation Payments”) in an
amount equal to (A) if paid in cash, the greater of (i) five percent (5%) of Gross Revenues for such respective quarter or (ii) twenty percent (20%) of Consolidated Net Income for such respective quarter or (B) if paid
in Common Stock, the greater of (i) fifty percent (50%) of Gross Revenues for such respective quarter or (ii) one hundred percent (100%) of Consolidated Net Income for such respective quarter. Pursuant to the Section 8.01A
below, the Purchaser shall elect at the end of each calendar quarter whether to receive the Quarterly Participation Payment in cash, Common Stock or a combination. For purposes of determining the number of shares of that shall be issued upon the
payment of all or part of a Quarterly Participation Payment in Common Stock, the dollar amount of the Quarterly Participation Payment that Purchaser elects to be paid in Common Stock shall be divided by the Conversion Price. The aggregate amount of
Quarterly Participation Payments to which Purchaser is entitled is $4,590,000. Nothing in this Section 8.01 shall alter the obligation of the Company or the Parent to receive the prior written agreement of Purchaser before entering into any
transaction identified in Sections 6.03 or 6.08 of this Agreement.” 
 1.4 Addition of New Sections 8.01A through 8.01.

certified and signed by its Chief Financial Officer, stating the amount of Gross Revenues and Consolidated Net Income during the calendar quarter. Within fifteen 15 days of delivery of the certificate, Purchaser shall deliver PRO written notice (the
“Participation Payment Election Notice”) stating what amount of its Quarterly Participation Payment it demands to be paid in cash and what amount it demands to be converted into Common Stock. Payment of the cash portion of a
Quarterly Participation Payment shall occur no later than the fifteenth (15th) day following the date of the Quarterly Participation Payment Election Notice, at the Purchaser’s office or at such other place agreed to by Purchaser. The
issuance of the Common Stock portion of a Quarterly Participation Payment shall be deemed effective as of the date of the Participation Payment Election Notice, without any further action on Purchaser’s or PRO’s part. PRO shall deliver to
Purchaser certificate(s) representing the number of shares Common Stock acquired by Purchaser, and the dollar amount of the Quarterly Participation Payment which was converted shall be deemed a reduction in the total amount of Quarterly
Participation Payments owed to Purchaser. 
  

 3 

 “Section 8.01B. Qualified Public Offering. Immediately prior to PRO’s
sale of its Common Stock in a firm commitment underwritten public offering pursuant to a registration statement under the Securities Act of 1933, as amended, covering the offer and sale of Common Stock for the account of PRO in which the net
proceeds of PRO are equal to or greater than Ten Million and No/100 Dollars ($10,000,000.00) (before deduction of underwriters’ commissions and expenses) (“Qualified Public Offering”), the Purchaser, in its sole discretion, may
convert all or part of any accrued Quarterly Participation Payments into Common Stock of PRO in connection with such Qualified Public Offering. 
 “Section 8.01C Conversion Price Adjustment. The Conversion Price shall be subject to adjustment from time to time upon the happening of any of the following events: 
 (a) Adjustment for Stock Splits and Combinations. If PRO shall at any time or from time to time after the date of this Amendment effect a
subdivision of its outstanding Common Stock, the Conversion Price in effect immediately before that subdivision shall be proportionately decreased so that the number of shares of Common Stock issuable on conversion of a Quarterly Participation
Payment shall be increased in proportion to such increase in the aggregate number of shares of Common Stock outstanding. If PRO shall at any time or from time to time after the date of this Amendment combine the outstanding shares of Common Stock,
the Conversion Price in effect immediately before the combination shall be proportionately increased so that the number of shares of Common Stock issuable on conversion of a Quarterly Participation Payment shall be decreased in proportion to such
decrease in the aggregate number of shares of Common Stock outstanding. Any adjustment under this subsection shall become effective at the close of business on the date the subdivision or combination becomes effective. 
 (b) Adjustment for Certain Dividends and Distributions. In the event PRO at any time or from time to time after the date of this Amendment shall
make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable on the Common Stock in additional shares of Common Stock, then and in each such event the Conversion
Price in effect immediately before such event shall be decreased as of the time of such issuance or, in the event such a record date shall have been fixed, as of the close of business on such record date, by multiplying the Conversion Price then in
effect by a fraction: (i) the numerator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close of business on such record date, and (ii) the 

  

 4 

 
denominator of which shall be the total number of shares of Common Stock issued and outstanding immediately prior to the time of such issuance or the close
of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution. Notwithstanding the foregoing, if such record date shall have been fixed and such dividend is not fully paid or if such
distribution is not fully made on the date fixed therefor, the Conversion Price shall be recomputed accordingly as of the close of business on such record date and thereafter the Conversion Price shall be adjusted pursuant to this subsection as of
the time of actual payment of such dividends or distributions. 
 (c) Adjustments for Other Dividends and Distributions. In the event
PRO at any time or from time to time after the date of this Amendment shall make or issue, or fix a record date for the determination of holders of Common Stock entitled to receive, a dividend or other distribution payable in securities of PRO
(other than a distribution of shares of Common Stock in respect of outstanding shares of Common Stock) or in other property, then and in each such event provision shall be made so that Purchaser shall receive upon conversion of a Quarterly
Participation Payment, in addition to the number of shares of Common Stock receivable thereupon, the kind and amount of securities of PRO, cash or other property which they would have been entitled to receive had the Quarterly Participation Payment
been converted into Common Stock on the date of such event and had Purchaser thereafter, during the period from the date of such event to and including the conversion date, retained such securities receivable by it as aforesaid during such period,
giving application to all adjustments called for during such period under this paragraph. 
 (d) Merger or Consolidation. In case of
any merger or consolidation of PRO with any corporation or other entity, other than a consolidation or merger in which PRO is the surviving entity and which does not result in any reclassification or change of the outstanding Common Stock, the right
to convert the Quarterly Participation Payments into PRO Common Stock shall be automatically adjusted to represent the right to purchase at the Conversion Price the number of shares of Common Stock or other securities or assets that Purchaser would
have been entitled to receive if Purchaser had converted all unpaid and unearned Quarterly Participation Payments on or prior to the effective date of such merger or consolidation; provided however that the accrual of Quarterly Participation
Payments, and Purchaser’s option to receive some or all of such Quarterly Participation Payments in cash, shall remain subject to Section 8.01A 
  

 5 

 (e) Issuances. If after the date of this Amendment and until the maximum possible amount of
Quarterly Participation Payments have been paid in cash or have been converted into Common Stock of PRO (or other securities pursuant to Section 8.01C(d) above), PRO issues to any investor or other Person other than Purchaser, Common Stock or
other equity securities of PRO, or any rights convertible into or options to purchase Common Stock or other equity securities of PRO (the “New Issuance”), for a price per share which is less than the Conversion Price then in effect
(the “Dilutive Price”), then the Conversion Price shall be multiplied by a fraction, of which the denominator shall be the number of shares of Common Stock outstanding on the date of the New Issuance plus the number of additional
shares of Common Stock issued or offered for subscription or purchase in the New Issuance, and of which the numerator shall be the number of shares of Common Stock outstanding on the date of such New Issuance plus the number of shares which the
aggregate offering price of the total number of shares so offered (assuming receipt by PRO in full of all consideration payable in connection with such New Issuance) would purchase at the Dilutive Price. Notwithstanding the foregoing or any other
provision herein to the contrary, no adjustment to the Conversion Price will be required as a result of any issuance by PRO of any Common Stock, any other class of capital stock, or any other securities, options, rights, or warrants with respect
thereto (A) pursuant to any stock option plan, restricted stock plan or other compensatory plan or arrangement with any officer, director, employee or consultant of PRO or any affiliated entity, (B) pursuant to or in connection with any
agreement or understanding in effect on or before the date hereof, (C) pursuant to or in connection with any merger, consolidation, statutory share exchange, self tender offer for all or substantially all Common Stock, sale of all or
substantially all of PRO’s assets or recapitalization of the Common Stock of PRO, or (D) to any vendor, customer or other person or entity with which PRO has or is attempting to develop a business relationship. 
 (f) Calculations. No adjustment in the Conversion Price shall be required unless such adjustment would require a cumulative increase or decrease of
at least $0.05 in such price; provided, however, that any adjustments that by reason of this subparagraph (f) are not required to be made shall be carried forward and taken into account in any subsequent adjustment until made. Notwithstanding
any other provisions of this Section 8.01C, PRO shall not be required to make any adjustment of the Conversion Price for the issuance of any Common Stock pursuant to any plan providing for the reinvestment of dividends or interest payable on
securities of PRO and the investment of additional optional amounts in Common Stock under such plan. All calculations under this Section 8.01C shall be made to the nearest cent (with $.005 being rounded upward) or to the nearest
one-tenth of a share (with .05 of a share being rounded upward), as the case may be. 
  

 6 

 (g) Certificates as to Adjustments. Upon the occurrence of each adjustment or readjustment of the
Price pursuant to this Section 8.01C, PRO at its expense shall, as promptly as reasonably practicable but in any event not later than 10 days thereafter, compute such adjustment or readjustment in accordance with the terms hereof and
furnish to Purchaser a certificate setting forth such adjustment or readjustment (including the kind and amount of securities, cash or other property into which the maximum Quarterly Participation Payments are convertible) and showing in detail the
facts upon which such adjustment or readjustment is based. PRO shall, as promptly as reasonably practicable after the written request at any time of Purchaser (but in any event not later than 10 days thereafter), furnish or cause to be furnished to
such holder a certificate setting forth (i) the Conversion Price then in effect, and (ii) the number of shares of Common Stock and the amount, if any, of other securities, cash or property which then would be received upon the conversion
of the maximum Quarterly Participation Payments.
