SECURED CONVERTIBLE PROMISSORY NOTE

            FOR VALUE RECEIVED, SILVER DRAGON RESOURCES INC., a Delaware corporation (“Borrower”), promises to pay to TONAQUINT, INC., a Utah corporation, or its successors or assigns (“Lender”), $[__________] and any interest, fees, charges, and late fees on ___________ (the “Maturity Date”) in accordance with the terms set forth herein and to pay interest on the Outstanding Balance at the rate of twelve percent (12%) per annum from the Purchase Price Date until the same is paid in full. This Secured Convertible Promissory Note (this “Note”) is issued and made effective as of April 7, 2016 (the “Effective Date”). This Note is issued pursuant to that certain Settlement and Securities Purchase Agreement dated April 7, 2016, as the same may be amended from time to time, by and between Borrower and Lender (the “Purchase Agreement”). All interest calculations hereunder shall be computed on the basis of a 360-day year comprised of twelve (12) thirty (30) day months, shall compound daily and shall be payable in accordance with the terms of this Note. Certain capitalized terms used herein are defined in Attachment 1 attached hereto and incorporated herein by this reference.

            This Note carries an OID of [__________]. In addition, Borrower agrees to pay $[__________] to Lender to cover Lender’s legal fees, accounting costs, due diligence, monitoring and other transaction costs incurred in connection with the purchase and sale of this Note (the “Transaction Expense Amount”), all of which amount is included in the initial principal balance of this Note. The purchase price for this Note shall be $[__________] (the “Purchase Price”), computed as follows: $[__________] original principal balance, less the OID, less the Transaction Expense Amount. The Purchase Price (as defined in the Purchase Agreement) shall be payable by a wire transfer of immediately available funds in the amount of the Purchase Price.

            1.        Payment; Prepayment. Provided there is an Outstanding Balance, on each Installment Date (as defined below), Borrower shall pay to Lender an amount equal to the Installment Amount (as defined below) due on such Installment Date in accordance with Section 8. The entire remaining Outstanding Balance of this Note shall be due and payable on the Maturity Date. All payments owing hereunder shall be in lawful money of the United States of America or Conversion Shares (as defined below), as provided for herein, and delivered to Lender at the address furnished to Borrower for that purpose. All payments shall be applied first to (a) costs of collection, if any, then to (b) fees and charges, if any, then to (c) accrued and unpaid interest, and thereafter, to (d) principal. Notwithstanding the foregoing, Borrower may, but only with Lender’s prior written consent, pay, without penalty, all or any portion of the Outstanding Balance along with any accrued but unpaid interest on this Note at any time prior to the Maturity Date.

            2.        Security. This Note is secured by: (a) that certain Security Agreement of even date herewith by and between Borrower and Lender, as the same may be amended from time to time (the “Security Agreement”), whereby Borrower granted a security interest in all of its assets in favor of Lender to secure the performance of its obligations under this Note, as more specifically set forth in the Security Agreement, all the terms and conditions of which are hereby incorporated into and made a part of this Note; and (b) that certain Pledge Agreement of even date herewith by and between Borrower and Lender, as the same may be amended from time to time (the “Pledge Agreement”), whereby Borrower pledged all of its right, title and interest in and to the Sino-Top Interest to secure the performance of its obligations under this Note, as more specifically set forth in the Pledge Agreement, all the terms and conditions of which are hereby incorporated into and made a part of this Note.

            3.        Lender Optional Conversion.

                       3.1.        Lender Conversion Price. Subject to adjustment as set forth in this Note, the conversion price for each Lender Conversion (as defined below) shall be $[____] (the “Lender Conversion Price”). However, in the event the Market Capitalization falls below $[______] at any time, then in such event (a) the Lender Conversion Price for all Lender Conversions occurring after the first date of such occurrence shall equal the lower of the Lender Conversion Price and the Market Price as of any applicable date of Conversion, and (b) the true-up provisions of Section 11 below shall apply to all Lender Conversions that occur after the first date the Market Capitalization falls below $[______] provided that all references to the “Installment Notice” in Section 11 shall be replaced with references to a “Lender Conversion Notice” for purposes of this Section 3.1, all references to “Installment Conversion Shares” in Section 11 shall be replaced with references to “Lender Conversion Shares” for purposes of this Section 3.1, and all references to the “Installment Conversion Price” in Section 11 shall be replaced with references to the “Lender Conversion Price” for purposes of this Section 3.1.

                       3.2.        Lender Conversions. Lender has the right at any time after the six (6) month anniversary of the Purchase Price Date until the Outstanding Balance has been paid in full, including without limitation during or after any Fundamental Default Measuring Period, at its election, to convert (each instance of conversion is referred to herein as a “Lender Conversion”) all or any part of the Outstanding Balance into shares (“Lender Conversion Shares”) of fully paid and non-assessable common stock, $0.0001 par value per share (“Common Stock”), of Borrower as per the following conversion formula: the number of Lender Conversion Shares equals the amount being converted (the “Conversion Amount”) divided by the Lender Conversion Price. Conversion notices in the form attached hereto as Exhibit A (each, a “Lender Conversion Notice”) may be effectively delivered to Borrower by any method of Lender’s choice (including but not limited to facsimile, email, mail, overnight courier, or personal delivery), and all Lender Conversions shall be cashless and not require further payment from Lender. Borrower shall deliver the Lender Conversion Shares from any Lender Conversion to Lender in accordance with Section 9 below.

                     3.3.        Application to Installments. Notwithstanding anything to the contrary herein, including without limitation Section 8 hereof, Lender may, in its sole discretion, apply all or any portion of any Lender Conversion toward any Installment Conversion (as defined below), even if such Installment Conversion is pending, as determined in Lender’s sole discretion, by delivering written notice of such election (which notice may be included as part of the applicable Lender Conversion Notice) to Borrower at any date on or prior to the applicable Installment Date. In such event, Borrower may not elect to allocate such portion of the Installment Amount being paid pursuant to this Section 3.3 in the manner prescribed in Section 8.3; rather, Borrower must reduce the applicable Installment Amount by the Conversion Amount described in this Section 3.3.

            4.        Defaults; Remedies.

                       4.1.        Defaults. The following are events of default under this Note (each, an “Event of Default”): (a) Borrower shall fail to pay any principal, interest, fees, charges, or any other amount when due and payable hereunder; (b) Borrower shall fail to deliver any Lender Conversion Shares in accordance with the terms hereof; (c) Borrower shall fail to deliver any Installment Conversion Shares (as defined below) or True-Up Shares (as defined below) in accordance with the terms hereof; (d) a receiver, trustee or other similar official shall be appointed over Borrower or a material part of its assets and such appointment shall remain uncontested for twenty (20) days or shall not be dismissed or discharged within sixty (60) days; (e) Borrower shall become insolvent or generally fails to pay, or admits in writing its inability to pay, its debts as they become due, subject to applicable grace periods, if any; (f) Borrower shall make a general assignment for the benefit of creditors; (g) Borrower shall file a petition for relief under any bankruptcy, insolvency or similar law (domestic or foreign); (h) an involuntary proceeding shall be commenced or filed against Borrower; (i) Borrower shall default or otherwise fail to observe or perform any covenant, obligation, condition or agreement of Borrower contained herein or in any other Transaction Document (as defined in the Purchase Agreement), other than those specifically set forth in this Section 4.1 and Section 6 of the Purchase Agreement; (j) any representation, warranty or other statement made or furnished by or on behalf of Borrower to Lender herein, in any Transaction Document, or otherwise in connection with the issuance of this Note shall be false, incorrect, incomplete or misleading in any material respect when made or furnished; (k) the occurrence of a Fundamental Transaction without Lender’s prior written consent; (l) Borrower shall fail to put in place and maintain the Share Reserve as required under the Purchase Agreement; (m) Borrower effectuates a reverse split of its Common Stock without twenty (20) Trading Days prior written notice to Lender; (n) any money judgment, writ or similar process shall be entered or filed against Borrower or any subsidiary of Borrower or any of its property or other assets for more than $100,000.00, and shall remain unvacated, unbonded or unstayed for a period of twenty (20) calendar days unless otherwise consented to by Lender; (o) Borrower shall fail to be DWAC Eligible; or (p) Borrower shall fail to observe or perform any covenant set forth in Section 6 of the Purchase Agreement.

2

                       4.2.        Remedies. At any time and from time to time after Lender becoming aware of the occurrence of any Event of Default, Lender may accelerate this Note by written notice to Borrower, with the Outstanding Balance becoming immediately due and payable in cash at the Mandatory Default Amount. Notwithstanding the foregoing, at any time following the occurrence of any Event of Default, Lender may, at its option, elect to increase the Outstanding Balance by applying the Default Effect (subject to the limitation set forth below) via written notice to Borrower without accelerating the Outstanding Balance, in which event the Outstanding Balance shall be increased as of the date of the occurrence of the applicable Event of Default pursuant to the Default Effect, but the Outstanding Balance shall not be immediately due and payable unless so declared by Lender (for the avoidance of doubt, if Lender elects to apply the Default Effect pursuant to this sentence, it shall reserve the right to declare the Outstanding Balance immediately due and payable at any time and no such election by Lender shall be deemed to be a waiver of its right to declare the Outstanding Balance immediately due and payable as set forth herein unless otherwise agreed to by Lender in writing). Notwithstanding the foregoing, upon the occurrence of any Event of Default described in clauses (d), (e), (f), (g) or (h) of Section 4.1, the Outstanding Balance as of the date of acceleration shall become immediately and automatically due and payable in cash at the Mandatory Default Amount, without any written notice required by Lender. At any time following the occurrence of any Event of Default, upon written notice given by Lender to Borrower, interest shall accrue on the Outstanding Balance beginning on the date the applicable Event of Default occurred at an interest rate equal to the lesser of 22% per annum or the maximum rate permitted under applicable law (“Default Interest”); provided, however, that no Default Interest shall accrue during the Fundamental Default Measuring Period. For the avoidance of doubt, Lender may continue making Lender Conversions at any time following an Event of Default until such time as the Outstanding Balance is paid in full. Additionally, following the occurrence of any Event of Default, Borrower may, at its option, pay any Lender Conversion in cash instead of Lender Conversion Shares by paying to Lender on or before the applicable Delivery Date (as defined below) a cash amount equal to the number of Lender Conversion Shares set forth in the applicable Lender Conversion Notice multiplied by the highest intra-day trading price of the Common Stock that occurs during the period beginning on the date the applicable Event of Default occurred and ending on the date of the applicable Lender Conversion Notice. In connection with acceleration described herein, Lender need not provide, and Borrower hereby waives, any presentment, demand, protest or other notice of any kind, and Lender may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such acceleration may be rescinded and annulled by Lender at any time prior to payment hereunder and Lender shall have all rights as a holder of the Note until such time, if any, as Lender receives full payment pursuant to this Section 4.2. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon. Nothing herein shall limit Lender’s right to pursue any other remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to Borrower’s failure to timely deliver Conversion Shares upon Conversion of the Notes as required pursuant to the terms hereof.

3

                       4.3.        Fundamental Default Remedies. Notwithstanding anything to the contrary herein, in addition to all other remedies set forth herein, the Fundamental Liquidated Damages Amount shall be added to the Outstanding Balance upon Lender’s delivery to Borrower of a notice (which notice Lender may deliver to Borrower at any time following the occurrence of a Fundamental Default) setting forth its election to declare a Fundamental Default and the Fundamental Liquidated Damages Amount that will be added to the Outstanding Balance.

                       4.4.        Certain Additional Rights. Notwithstanding anything to the contrary herein, in the event Borrower fails to make any payment or otherwise to deliver any Conversion Shares as and when required under this Note, then (a) the Lender Conversion Price for all Lender Conversions occurring after the date of such failure to pay shall equal the lower of the Lender Conversion Price and the Market Price as of any applicable date of Conversion, and (b) the true-up provisions of Section 11 below shall apply to all Lender Conversions that occur after the date of such failure to pay, provided that all references to the “Installment Notice” in Section 11 shall be replaced with references to a “Lender Conversion Notice” for purposes of this Section 4.4, all references to “Installment Conversion Shares” in Section 11 shall be replaced with references to “Lender Conversion Shares” for purposes of this Section 4.4, and all references to the “Installment Conversion Price” in Section 11 shall be replaced with references to the “Lender Conversion Price” for purposes of this Section 4.4. For the avoidance of doubt, Lender’s exercise of the rights granted to it pursuant to this Section 4.4 shall not relieve Borrower of its obligation to continue paying the Installment Amount on all future Installment Dates.

                       4.5.        Cross Default. A breach or default by Borrower of any covenant or other term or condition contained in any Other Agreements shall, at the option of Lender, be considered an Event of Default under this Note, in which event Lender shall be entitled (but in no event required) to apply all rights and remedies of Lender under the terms of this Note.

            5.        Unconditional Obligation; No Offset. Borrower acknowledges that this Note is an unconditional, valid, binding and enforceable obligation of Borrower not subject to offset, deduction or counterclaim of any kind. Borrower hereby waives any rights of offset it now has or may have hereafter against Lender, its successors and assigns, and agrees to make the payments or Conversions called for herein in accordance with the terms of this Note.

            6.        Waiver. No waiver of any provision of this Note shall be effective unless it is in the form of a writing signed by the party granting the waiver. No waiver of any provision or consent to any prohibited action shall constitute a waiver of any other provision or consent to any other prohibited action, whether or not similar. No waiver or consent shall constitute a continuing waiver or consent or commit a party to provide a waiver or consent in the future except to the extent specifically set forth in writing.

            7.        Rights Upon Issuance of Securities.

                       7.1.        Subsequent Equity Sales. Except with respect to Excluded Securities, if Borrower or any subsidiary thereof, as applicable, at any time this Note is outstanding, shall sell, issue or grant any Common Stock, option to purchase Common Stock, right to reprice, preferred shares convertible into Common Stock, or debt, warrants, options or other instruments or securities to Lender or any third party which are convertible into or exercisable for shares of Common Stock (collectively, the “Equity Securities”), including without limitation any Deemed Issuance, at an effective price per share less than the then effective Lender Conversion Price (such issuance is referred to herein as a “Dilutive Issuance”), then, the Lender Conversion Price shall be automatically reduced and only reduced to equal such lower effective price per share. If the holder of any Equity Securities so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options, or rights per share which are issued in connection with such Dilutive Issuance, be entitled to receive shares of Common Stock at an effective price per share that is less than the Lender Conversion Price, such issuance shall be deemed to have occurred for less than the Lender Conversion Price on the date of such Dilutive Issuance, and the then effective Lender Conversion Price shall be reduced and only reduced to equal such lower effective price per share. Such adjustments described above to the Lender Conversion Price shall be permanent (subject to additional adjustments under this section), and shall be made whenever such Equity Securities are issued. Borrower shall notify Lender, in writing, no later than the Trading Day following the issuance of any Equity Securities subject to this Section 7.1, indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price, or other pricing terms (such notice, the “Dilutive Issuance Notice”). For purposes of clarification, whether or not Borrower provides a Dilutive Issuance Notice pursuant to this Section 7.1, upon the occurrence of any Dilutive Issuance, on the date of such Dilutive Issuance the Lender Conversion Price shall be lowered to equal the applicable effective price per share regardless of whether Borrower or Lender accurately refers to such lower effective price per share in any Installment Notice or Lender Conversion Notice.

4

                       7.2.        Adjustment of Lender Conversion Price upon Subdivision or Combination of Common Stock. Without limiting any provision hereof, if Borrower at any time on or after the Effective Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Lender Conversion Price in effect immediately prior to such subdivision will be proportionately reduced. Without limiting any provision hereof, if Borrower at any time on or after the Effective Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of Common Stock into a smaller number of shares, the Lender Conversion Price in effect immediately prior to such combination will be proportionately increased. Any adjustment pursuant to this Section 7.2 shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this Section 7.2 occurs during the period that a Lender Conversion Price is calculated hereunder, then the calculation of such Lender Conversion Price shall be adjusted appropriately to reflect such event.

                       7.3.        Other Events. In the event that Borrower (or any subsidiary) shall take any action to which the provisions hereof are not strictly applicable, or, if applicable, would not operate to protect Lender from dilution or if any event occurs of the type contemplated by the provisions of this Section 7 but not expressly provided for by such provisions (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features), then Borrower’s board of directors shall in good faith determine and implement an appropriate adjustment in the Lender Conversion Price so as to protect the rights of Lender, provided that no such adjustment pursuant to this Section 7.3 will increase the Lender Conversion Price as otherwise determined pursuant to this Section 7, provided further that if Lender does not accept such adjustments as appropriately protecting its interests hereunder against such dilution, then Borrower’s board of directors and Lender shall agree, in good faith, upon an independent investment bank of nationally recognized standing to make such appropriate adjustments, whose determination shall be final and binding and whose fees and expenses shall be borne by Borrower.

            8.        Borrower Installments.

                       8.1.        Installment Conversion Price. Subject to the adjustments set forth herein, the conversion price for each Installment Conversion (the “Installment Conversion Price”) shall be the lesser of (a) the Lender Conversion Price, and (b) the Market Price.

                       8.2.        Installment Conversions. Beginning on [__________] and on the same day of each month thereafter until the Maturity Date (each, an “Installment Date”), if paying in cash, Borrower shall pay to Lender the applicable Installment Amount due on such date subject to the provisions of this Section 8, and if paying in Installment Conversion Shares (as defined below), Borrower shall deliver such Installment Conversion Shares on or before the Delivery Date. Payments of each Installment Amount may be made (a) in cash, or (b) by converting such Installment Amount into shares of Common Stock (“Installment Conversion Shares”, and together with the Lender Conversion Shares, the “Conversion Shares”) in accordance with this Section 8 (each an “Installment Conversion”) per the following formula: the number of Installment Conversion Shares equals the portion of the applicable Installment Amount being converted divided by the Installment Conversion Price, or (c) by any combination of the foregoing, so long as the cash is delivered to Lender on the applicable Installment Date and the Installment Conversion Shares are delivered to Lender on or before the applicable Delivery Date. Notwithstanding the foregoing, Borrower will not be entitled to elect an Installment Conversion with respect to any portion of any applicable Installment Amount and shall be required to pay the entire amount of such Installment Amount in cash if on the applicable Installment Date there is an Equity Conditions Failure, and such failure is not waived in writing by Lender. Moreover, in the event Borrower desires to pay all or any portion of any Installment Amount in cash, it must notify Lender in writing of such election and the portion of the applicable Installment Amount it elects to pay in cash not more than twenty-five (25) or less than fifteen (15) Trading Days prior to the applicable Installment Date. If Borrower fails to so notify Lender, it shall not be permitted to elect to pay any portion of such Installment Amount in cash unless otherwise agreed to by Lender in writing or proposed by Lender in an Installment Notice delivered by Lender to Borrower. Notwithstanding that failure to repay this Note in full by the Maturity Date is an Event of Default, the Installment Dates shall continue after the Maturity Date pursuant to this Section 8 until the Outstanding Balance is repaid in full, provided that Lender shall, in Lender’s sole discretion, determine the Installment Amount for each Installment Date after the Maturity Date.

                       8.3.        Allocation of Installment Amounts. Subject to Section 8.2 regarding an Equity Conditions Failure, for each Installment Date, Borrower may elect to allocate the amount of the applicable Installment Amount between cash and via an Installment Conversion, by email or fax delivery of a notice to Lender substantially in the form attached hereto as Exhibit B (each, an “Installment Notice”), provided, that to be effective, each applicable Installment Notice must be received by Lender not more than twenty-five (25) or less than fifteen (15) Trading Days prior to the applicable Installment Date. If Lender has not received an Installment Notice within such time period, then Lender may prepare the Installment Notice and deliver the same to Borrower by fax or email. Following its receipt of such Installment Notice, Borrower may either ratify Lender’s proposed allocation in the applicable Installment Notice or elect to change the allocation by written notice to Lender by email or fax on or before 12:00 p.m. New York time on the applicable Installment Date, so long as the sum of the cash payments and the amount of Installment Conversions equal the applicable Installment Amount, provided that Lender must approve any increase to the portion of the Installment Amount payable in cash. If Borrower fails to notify Lender of its election to change the allocation prior to the deadline set forth in the previous sentence (and seek approval to increase the amount payable in cash), it shall be deemed to have ratified and accepted the allocation set forth in the applicable Installment Notice prepared by Lender. If neither Borrower nor Lender prepare and deliver to the other party an Installment Notice as outlined above, then Borrower shall be deemed to have elected that the entire Installment Amount be converted via an Installment Conversion.

6

Borrower acknowledges and agrees that regardless of which party prepares the applicable Installment Notice, the amounts and calculations set forth thereon are subject to correction or adjustment because of error, mistake, or any adjustment resulting from an Event of Default or other adjustment permitted under the Transaction Documents (an “Adjustment”). Furthermore, no error or mistake in the preparation of such notices, or failure to apply any Adjustment that could have been applied prior to the preparation of an Installment Notice may be deemed a waiver of Lender’s right to enforce the terms of any Note, even if such error, mistake, or failure to include an Adjustment arises from Lender’s own calculation. Borrower shall deliver the Installment Conversion Shares from any Installment Conversion to Lender in accordance with Section 9 below on or before each applicable Delivery Date.

            9.        Method of Conversion Share Delivery. On or before the close of business on the third (3^rd) Trading Day following the Installment Date or the third (3^rd) Trading Day following the date of delivery of a Lender Conversion Notice, as applicable (the “Delivery Date”), Borrower shall, provided it is DWAC Eligible at such time, deliver or cause its transfer agent to deliver the applicable Conversion Shares electronically via DWAC to the account designated by Lender in the applicable Lender Conversion Notice or Installment Notice. If Borrower is not DWAC Eligible, it shall deliver to Lender or its broker (as designated in the Lender Conversion Notice or Installment Notice, as applicable), via reputable overnight courier, a certificate representing the number of shares of Common Stock equal to the number of Conversion Shares to which Lender shall be entitled, registered in the name of Lender or its designee. For the avoidance of doubt, Borrower has not met its obligation to deliver Conversion Shares by the Delivery Date unless Lender or its broker, as applicable, has actually received the certificate representing the applicable Conversion Shares no later than the close of business on the relevant Delivery Date pursuant to the terms set forth above. Moreover, and notwithstanding anything to the contrary herein or in any other Transaction Document, in the event Borrower or its transfer agent refuses to deliver any Conversion Shares to Lender on grounds that such issuance is in violation of Rule 144 under the Securities Act of 1933, as amended (“Rule 144”), Borrower shall deliver or cause its transfer agent to deliver the applicable Conversion Shares to Lender with a restricted securities legend, but otherwise in accordance with the provisions of this Section 9. In conjunction therewith, Borrower will also deliver to Lender a written opinion from its counsel or its transfer agent’s counsel opining as to why the issuance of the applicable Conversion Shares violates Rule 144.

            10.      Conversion Delays. If Borrower fails to deliver Conversion Shares or True-Up Shares in accordance with the timeframes stated in Sections 9 or 11, as applicable, Lender, at any time prior to selling all of those Conversion Shares or True-Up Shares, as applicable, may rescind in whole or in part that particular Conversion attributable to the unsold Conversion Shares or True-Up Shares, with a corresponding increase to the Outstanding Balance (any returned amount will tack back to the Purchase Price Date for purposes of determining the holding period under Rule 144). In addition, for each Lender Conversion, in the event that Lender Conversion Shares are not delivered by the fourth Trading Day (inclusive of the day of the Lender Conversion), a late fee equal to the greater of (a) $500.00 and (b) 2% of the applicable Lender Conversion Share Value rounded to the nearest multiple of $100.00 (but in any event the cumulative amount of such late fees for each Lender Conversion shall not exceed 200% of the applicable Lender Conversion Share Value) will be assessed for each day after the third Trading Day (inclusive of the day of the Lender Conversion) until Lender Conversion Share delivery is made; and such late fee will be added to the Outstanding Balance (such fees, the “Conversion Delay Late Fees”). For illustration purposes only, if Lender delivers a Lender Conversion Notice to Borrower pursuant to which Borrower is required to deliver 100,000 Lender Conversion Shares to Lender and on the Delivery Date such Lender Conversion Shares have a Lender Conversion Share Value of $20,000.00 (assuming a Closing Trade Price on the Delivery Date of $0.20 per share of Common Stock), then in such event a Conversion Delay Late Fee in the amount of $500.00 per day (the greater of $500.00 per day and $20,000.00 multiplied by 2%, which is $400.00) would be added to the Outstanding Balance of the Note until such Lender Conversion Shares are delivered to Lender. For purposes of this example, if the Lender Conversion Shares are delivered to Lender twenty (20) days after the applicable Delivery Date, the total Conversion Delay Late Fees that would be added to the Outstanding Balance would be $10,000.00 (20 days multiplied by $500.00 per day). If the Lender Conversion Shares are delivered to Lender one hundred (100) days after the applicable Delivery Date, the total Conversion Delay Late Fees that would be added to the Outstanding Balance would be $40,000.00 (100 days multiplied by $500.00 per day, but capped at 200% of the Lender Conversion Share Value).

7

            11.      True-Up. On the date that is twenty (20) Trading Days (a “True-Up Date”) from each date that the Installment Conversion Shares delivered by Borrower to Lender become Free Trading, there shall be a true-up where Borrower shall deliver to Lender additional Installment Conversion Shares (“True-Up Shares”) if the Installment Conversion Price as of the True-Up Date is less than the Installment Conversion Price used in the applicable Installment Notice. In such event, Borrower shall deliver to Lender within three (3) Trading Days of the True-Up Date (the “True-Up Share Delivery Date”) a number of True-Up Shares equal to the difference between the number of Installment Conversion Shares that would have been delivered to Lender on the True-Up Date based on the Installment Conversion Price as of the True-Up Date and the number of Installment Conversion Shares originally delivered to Lender pursuant to the applicable Installment Notice. For the avoidance of doubt, if the Installment Conversion Price as of the True-Up Date is higher than the Installment Conversion Price set forth in the applicable Installment Notice, then Borrower shall have no obligation to deliver True-Up Shares to Lender, nor shall Lender have any obligation to return any excess Installment Conversion Shares to Borrower under any circumstance. For the convenience of Borrower only, Lender may, in its sole discretion, deliver to Borrower a notice (pursuant to a form of notice substantially in the form attached hereto as Exhibit C) informing Borrower of the number of True-Up Shares it is obligated to deliver to Lender as of any given True-Up Date, provided that if Lender does not deliver any such notice, Borrower shall not be relieved of its obligation to deliver True-Up Shares pursuant to this Section 11. Notwithstanding the foregoing, if Borrower fails to deliver any required True-Up Shares on or before any applicable True-Up Share Delivery Date, then in such event the Outstanding Balance of this Note will automatically increase by a sum equal to the number of True-Up Shares deliverable as of the applicable True-Up Date multiplied by the Market Price for the Common Stock as of the applicable True-Up Date (under Lender’s and Borrower’s expectations that any such increase will tack back to the Purchase Price Date for purposes of determining the holding period under Rule 144).

            12.      Sale of Sino-Top Interest.

                       12.1.        Upon the sale of the Sino-Top Interest or all or substantially all of Borrower’s assets, Lender may, at its election, cause Borrower to either (a) repay the Outstanding Balance, or (b) redeem this Note in the amount of the Redemption Value (either (a) or (b) above, as elected by Lender, the “Payoff Amount”).

                       12.2.        In furtherance of the foregoing, at any time while this Note is outstanding, if Borrower desires to engage in any transaction whereby the Sino-Top Interest would be sold, transferred or assigned (the “Interest Sale”), then the following shall apply: (a) Borrower will notify Lender in writing of the final terms and conditions of the Interest Sale and (i) if the purchase price (in U.S. Dollars) of the Interest Sale is greater than the Redemption Value, request a Payoff Letter from Lender, or (i) if the purchase price (in U.S. Dollars) of the Interest Sale is less than the Redemption Value, request Lender’s consent to the Interest Sale and a Payoff Letter from Lender; (b) if applicable, Lender will provide the Payoff Amount by delivering a Payoff Letter to Borrower; (c) upon the closing of the Interest Sale, Borrower shall cause the buyer to deliver the Payoff Amount directly to the account designated by Lender in the Payoff Letter; and (d) upon receipt of the Payoff Amount, Lender shall promptly confirm such receipt and take any actions reasonably necessary to release Lender’s lien on and security interest in the Sino-Top Interest.

8

            13.      Ownership Limitation. Notwithstanding anything to the contrary contained in this Note or the other Transaction Documents, if at any time Lender shall or would be issued shares of Common Stock under any of the Transaction Documents, but such issuance would cause Lender (together with its affiliates) to beneficially own a number of shares exceeding 9.99% of the number of shares of Common Stock outstanding on such date (including for such purpose the shares of Common Stock issuable upon such issuance) (the “Maximum Percentage”), then Borrower must not issue to Lender shares of Common Stock which would exceed the Maximum Percentage. For purposes of this section, beneficial ownership of Common Stock will be determined pursuant to Section 13(d) of the 1934 Act. The shares of Common Stock issuable to Lender that would cause the Maximum Percentage to be exceeded are referred to herein as the “Ownership Limitation Shares”. Borrower will reserve the Ownership Limitation Shares for the exclusive benefit of Lender. From time to time, Lender may notify Borrower in writing of the number of the Ownership Limitation Shares that may be issued to Lender without causing Lender to exceed the Maximum Percentage. Upon receipt of such notice, Borrower shall be unconditionally obligated to immediately issue such designated shares to Lender, with a corresponding reduction in the number of the Ownership Limitation Shares. By written notice to Borrower, Lender may increase, decrease or waive the Maximum Percentage as to itself but any such waiver will not be effective until the 61st day after delivery thereof. The foregoing 61-day notice requirement is enforceable, unconditional and non-waivable and shall apply to all affiliates and assigns of Lender.

            14.      Payment of Collection Costs.

Borrower also agrees to pay for any costs, fees or charges of its transfer agent that are charged to Lender pursuant to any Conversion or issuance of shares pursuant to this Note.

            15.      Opinion of Counsel. In the event that an opinion of counsel is needed for any matter related to this Note, Lender has the right to have any such opinion provided by its counsel. Lender also has the right to have any such opinion provided by Borrower’s counsel.

            16.      Governing Law; Venue. This Note shall be construed and enforced in accordance with, and all questions concerning the construction, validity, interpretation and performance of this Note shall be governed by, the internal laws of the State of Utah, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Utah or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Utah. The provisions set forth in the Purchase Agreement to determine the proper venue for any disputes are incorporated herein by this reference.

            17.      Resolution of Disputes.

                       17.1.        Arbitration of Disputes. By its acceptance of this Note, each party agrees to be bound by the Arbitration Provisions (as defined in the Purchase Agreement) set forth as an exhibit to the Purchase Agreement.

            23.      Liquidated Damages. Lender and Borrower agree that in the event Borrower fails to comply with any of the terms or provisions of this Note, Lender’s damages would be uncertain and difficult (if not impossible) to accurately estimate because of the parties’ inability to predict future interest rates, future share prices, future trading volumes and other relevant factors. Accordingly, Lender and Borrower agree that any fees, balance adjustments, Default Interest or other charges assessed under this Note are not penalties but instead are intended by the parties to be, and shall be deemed, liquidated damages (under Lender’s and Borrower’s expectations that any such liquidated damages will tack back to the Purchase Price Date for purposes of determining the holding period under Rule 144).

            24.      Waiver of Jury Trial. EACH OF LENDER AND BORROWER IRREVOCABLY WAIVES ANY AND ALL RIGHTS SUCH PARTY MAY HAVE TO DEMAND THAT ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR IN ANY WAY RELATED TO THIS NOTE OR THE RELATIONSHIPS OF THE PARTIES HERETO BE TRIED BY JURY. THIS WAIVER EXTENDS TO ANY AND ALL RIGHTS TO DEMAND A TRIAL BY JURY ARISING UNDER COMMON LAW OR ANY APPLICABLE STATUTE, LAW, RULE OR REGULATION. FURTHER, EACH PARTY HERETO ACKNOWLEDGES THAT SUCH PARTY IS KNOWINGLY AND VOLUNTARILY WAIVING SUCH PARTY’S RIGHT TO DEMAND TRIAL BY JURY.

            25.      Voluntary Agreement. Borrower has carefully read this Note and has asked any questions needed for Borrower to understand the terms, consequences and binding effect of this Note and fully understand them. Borrower has had the opportunity to seek the advice of an attorney of Borrower’s choosing, or has waived the right to do so, and is executing this Note voluntarily and without any duress or undue influence by Lender or anyone else.

            26.      Severability. If any part of this Note is construed to be in violation of any law, such part shall be modified to achieve the objective of Borrower and Lender to the fullest extent permitted by law and the balance of this Note shall remain in full force and effect.

            27.      Par Value Adjustments. If at any time Lender delivers a Lender Conversion Notice to Borrower and as of such date the Lender Conversion Price would be less than the Par Value, then, as liquidated damages, Borrower must pay to Lender the Par Value Adjustment Amount in cash within one (1) Trading Day of delivery of the applicable Conversion Notice (a “Par Value Adjustment”). If Borrower does not deliver the Par Value Adjustment Amount as required, then such amount shall

10

automatically be added to the Outstanding Balance. The number of Conversion Shares deliverable pursuant to any relevant Lender Conversion Notice following a Par Value Adjustment shall be equal to (a) the Conversion Amount, divided by (b) the Par Value. In the event of a Par Value Adjustment, Lender will use a Lender Conversion Notice in substantially the form attached hereto as Exhibit D.

ATTACHMENT 1
DEFINITIONS

            For purposes of this Note, the following terms shall have the following meanings:

            A1.        “Adjusted Outstanding Balance” means the Outstanding Balance of this Note as of the date the applicable Fundamental Default occurred less any Conversion Delay Late Fees included in such Outstanding Balance.

            A2.        “Approved Stock Plan” means any stock option plan which has been approved by the board of directors of Borrower and is in effect as of the Purchase Price Date, pursuant to which Borrower’s securities may be issued to any employee, officer or director for services provided to Borrower.

            A3.        “Balance Reduction Amount” means the portion of the Outstanding Balance that Lender elects to use to calculate the Deemed Redemption Shares; provided, however, that Lender may not elect to use a Balance Reduction Amount that would result in the deemed issuance of Deemed Redemption Shares that would exceed the Share Cap.

            A4.        “Bloomberg” means Bloomberg L.P. (or if that service is not then reporting the relevant information regarding the Common Stock, a comparable reporting service of national reputation selected by Lender and reasonably satisfactory to Borrower).

            A5.        “Closing Bid Price” and “Closing Trade Price” means the last closing bid price and last closing trade price, respectively, for the Common Stock on its principal market, as reported by Bloomberg, or, if its principal market begins to operate on an extended hours basis and does not designate the closing bid price or the closing trade price (as the case may be) then the last bid price or last trade price, respectively, of the Common Stock prior to 4:00:00 p.m., New York time, as reported by Bloomberg, or, if its principal market is not the principal securities exchange or trading market for the Common Stock, the last closing bid price or last trade price, respectively, of the Common Stock on the principal securities exchange or trading market where the Common Stock is listed or traded as reported by Bloomberg, or if the foregoing do not apply, the last closing bid price or last trade price, respectively, of the Common Stock in the over-the-counter market on the electronic bulletin board for the Common Stock as reported by Bloomberg, or, if no closing bid price or last trade price, respectively, is reported for the Common Stock by Bloomberg, the average of the bid prices, or the ask prices, respectively, of any market makers for the Common Stock as reported by OTC Markets Group, Inc., and any successor thereto. If the Closing Bid Price or the Closing Trade Price cannot be calculated for the Common Stock on a particular date on any of the foregoing bases, the Closing Bid Price or the Closing Trade Price (as the case may be) of the Common Stock on such date shall be the fair market value as mutually determined by Lender and Borrower. If Lender and Borrower are unable to agree upon the fair market value of the Common Stock, then such dispute shall be resolved in accordance with the procedures in Section 17.2. All such determinations shall be appropriately adjusted for any stock dividend, stock split, stock combination or other similar transaction during such period.

            A6.        “Conversion” means a Lender Conversion under Section 3 or an Installment Conversion under Section 8.

            A7.        “Conversion Factor” means [__]%, subject to the following adjustments. If at any time after the Effective Date, Borrower is not DWAC Eligible, then the then-current Conversion Factor will automatically be reduced by 5% for all future Conversions. If at any time after the Effective Date, the Conversion Shares are not DTC Eligible, then the then-current Conversion Factor will automatically be reduced by an additional 5% for all future Conversions. Finally, in addition to the Default Effect, if any Major Default occurs after the Effective Date, the Conversion Factor shall automatically be reduced for all future Conversions by an additional 5% for each of the first three (3) Major Defaults that occur after the Effective Date (for the avoidance of doubt, each occurrence of any Major Default shall be deemed to be a separate occurrence for purposes of the foregoing reductions in Conversion Factor, even if the same Major Default occurs three (3) separate times). For example, the first time Borrower is not DWAC Eligible, the Conversion Factor for future Conversions thereafter will be reduced from [__]% to [__]% for purposes of this example. Following such event, the first time the Conversion Shares are no longer DTC Eligible, the Conversion Factor for future Conversions thereafter will be reduced from [__]% to [__]%for purposes of this example. If, thereafter, there are three (3) separate occurrences of a Major Default pursuant to Section 4.1(c), then

Attachment 1 to Secured Convertible Promissory Note, Page 1

for purposes of this example the Conversion Factor would be reduced by 5% for the first such occurrence, and so on for each of the second and third occurrences of such Major Default.

            A8.        “Deemed Issuance” means an issuance of Common Stock that shall be deemed to have occurred on the latest possible permitted date pursuant to the terms hereof in the event Borrower fails to deliver Conversion Shares as and when required pursuant to Section 9 of the Note. For the avoidance of doubt, if Borrower has elected or is deemed under Section 8.3 to have elected to pay an Installment Amount in Installment Conversion Shares and fails to deliver such Installment Conversion Shares, such failure shall be considered a Deemed Issuance hereunder even if an Equity Conditions Failure exists at that time or other relevant date of determination.

            A9.        “Deemed Redemption Shares” means the number of shares of Common Stock Lender would be deemed to receive upon exercise of its redemption right set forth in Section 12 above calculated as follows: the Balance Reduction Amount divided by the Redemption Conversion Price.

            A10.        “Default Effect” means multiplying the Outstanding Balance as of the date the applicable Event of Default occurred by (a) 15% for each occurrence of any Major Default, or (b) 5% for each occurrence of any Minor Default, and then adding the resulting product to the Outstanding Balance as of the date the applicable Event of Default occurred, with the sum of the foregoing then becoming the Outstanding Balance under this Note as of the date the applicable Event of Default occurred; provided that the Default Effect may only be applied three (3) times hereunder with respect to Major Defaults and three (3) times hereunder with respect to Minor Defaults; and provided further that the Default Effect shall not apply to any Event of Default pursuant to Section 4.1(b) hereof.

            A11.        “DTC” means the Depository Trust Company or any successor thereto.

            A12.        “DTC Eligible” means, with respect to the Common Stock, that such Common Stock is eligible to be deposited in certificate form at the DTC, cleared and converted into electronic shares by the DTC and held in the name of the clearing firm servicing Lender’s brokerage firm for the benefit of Lender.

            A14.        “DWAC” means the DTC’s Deposit/Withdrawal at Custodian system.

            A15.        “DWAC Eligible” means that (a) Borrower’s Common Stock is eligible at DTC for full services pursuant to DTC’s operational arrangements, including without limitation transfer through DTC’s DWAC system, (b) Borrower has been approved (without revocation) by DTC’s underwriting department, (c) Borrower’s transfer agent is approved as an agent in the DTC/FAST Program, (d) the Conversion Shares are otherwise eligible for delivery via DWAC; (e) Borrower has previously delivered all Conversion Shares to Lender via DWAC; and (f) Borrower’s transfer agent does not have a policy prohibiting or limiting delivery of the Conversion Shares via DWAC.

Attachment 1 to Secured Convertible Promissory Note, Page 2

(g) Borrower shall have no knowledge of any fact that would reasonably be expected to cause any of the Conversion Shares to not be freely tradable without the need for registration under any applicable state securities laws (in each case, disregarding any limitation on conversion of this Note); (h) on each day during the Equity Conditions Measuring Period, Borrower otherwise shall have been in material compliance with each, and shall not have breached any, term, provision, covenant, representation or warranty of any Transaction Document; (i) without limiting clause (j) above, on each day during the Equity Conditions Measuring Period, there shall not have occurred an Event of Default or an event that with the passage of time or giving of notice would constitute an Event of Default; (k) on each Installment Date, the average and median daily dollar volume of the Common Stock on its principal market for the previous twenty (20) Trading Days shall be greater than $[______] (l) the ten (10) day average VWAP of the Common Stock is greater than $[______], and (m) the Common Stock shall be DWAC Eligible as of each applicable Installment Date or other date of determination.

            A17.        “Excluded Securities” means any shares of Common Stock, options, or convertible securities issued or issuable in connection with any Approved Stock Plan; provided that the option term, exercise price or similar provisions of any issuances pursuant to such Approved Stock Plan are not amended, modified or changed on or after the Purchase Price Date.

            A18.        “Free Trading” means that (a) the shares or certificate(s) representing the applicable shares of Common Stock have been cleared and approved for public resale by the compliance departments of Lender’s brokerage firm and the clearing firm servicing such brokerage, and (b) such shares are held in the name of the clearing firm servicing Lender’s brokerage firm and have been deposited into such clearing firm’s account for the benefit of Lender.

            A19.        “Fundamental Default” means that Borrower either fails to pay the entire Outstanding Balance to Lender on or before the Maturity Date or fails to pay the Mandatory Default Amount within three (3) Trading Days of the date Lender delivers any notice of acceleration to Borrower pursuant to Section 4.2 of this Note.

            A20.        “Fundamental Default Conversion Value” means the Adjusted Outstanding Balance multiplied by the highest Fundamental Default Ratio that occurs during the Fundamental Default Measuring Period.

            A21.        “Fundamental Default Measuring Period” means a number of months equal to the Outstanding Balance as of the date the Fundamental Default occurred divided by the Installment Amount, with such number being rounded up to the next whole month; provided, however, that if Borrower repays the entire Outstanding Balance prior to the conclusion of the Fundamental Default Measuring Period, the Fundamental Default Measuring Period shall end on the date of repayment. For illustration purposes only, if the Outstanding Balance were equal to $125,000.00 as of the date a Fundamental Default occurred and if the Installment Amount were $28,500.00, then the Fundamental Default Measuring Period would equal five (5) months calculated as follows: $125,000.00/ $28,500.00 equals 4.386, rounded up to five (5).

            A22.        “Fundamental Default Ratio” means a ratio that will be calculated on each Trading Day during the Fundamental Default Measuring Period by dividing the Closing Trade Price for the Common Stock on a given Trading Day by the Lender Conversion Price (as adjusted pursuant to the terms hereof) in effect for such Trading Day.

            A23.        “Fundamental Liquidated Damages Amount” means the greater of (a) (i) the quotient of the Outstanding Balance on the date the Fundamental Default occurred divided by the then-current Conversion Factor, minus (ii) the Outstanding Balance on the date the Fundamental Default occurred, or (b) the Fundamental Default Conversion Value.

            A24.        “Fundamental Transaction” means that (a) (i) Borrower or any of its subsidiaries shall, directly or indirectly, in one or more related transactions, consolidate or merge with or into (whether or not Borrower or any of its subsidiaries is the surviving corporation) any other person or entity, or (ii) Borrower or any of its subsidiaries shall, directly or indirectly, in one or more related transactions, sell, lease, license, assign, transfer, convey or otherwise dispose of all or substantially all of its respective properties or assets to any other person or entity, or (iii) Borrower or any of its subsidiaries shall, directly or indirectly, in one or more related transactions, allow any other person or entity to make a purchase, tender or exchange offer that is accepted by the holders of more than 50% of the outstanding shares of voting stock of Borrower (not including any shares of voting stock of Borrower held by the person or persons making or party to, or associated or affiliated with the persons or entities making or party to, such purchase, tender or exchange offer), or (iv) Borrower or any of its subsidiaries shall, directly or indirectly, in one or more related transactions, consummate a stock or share purchase agreement or other business combination

            A25.        “Incumbent Directors” means members of Borrower’s board of directors who either (i) are directors as of the Effective Date, or (ii) are elected, or nominated for election, to Borrower’s board of directors with the affirmative votes of at least a majority of the Incumbent Directors at the time of such election or nomination (but shall not include an individual whose election or nomination is in connection with an actual or threatened proxy contest relating to the election of directors to Borrower).

            A29.        “Mandatory Default Amount” means the greater of (a) the Outstanding Balance divided by the Installment Conversion Price on the date the Mandatory Default Amount is demanded, multiplied by the VWAP on the date the Mandatory Default Amount is demanded, or (b) the Outstanding Balance following the application of the Default Effect.

            A30.        “Market Capitalization” means the product equal to (a) the average VWAP of the Common Stock for the immediately preceding fifteen (15) Trading Days, multiplied by (b) the aggregate number of outstanding shares of Common Stock as reported on Borrower’s most recently filed Form 10-Q or Form 10-K.

            A31.        “Market Price” means the Conversion Factor multiplied by the average of the [____] lowest Closing Bid Prices in the twenty (20) Trading Days immediately preceding the applicable Conversion.

Attachment 1 to Secured Convertible Promissory Note, Page 4

would equal $16,666.67 computed as follows: (a) $66,666.67 (calculated as (i) (1) $50,000.00 divided by (2) $0.75 multiplied by (ii) $1.00) minus (b) $50,000.00.

For illustration purposes only, if for a given Conversion, the Conversion Amount was $20,000.00, the Conversion Price was $0.0008 and the Par Value was $0.001 then the Par Value Adjustment Amount would be $5,500.00 (25,000,000 Conversion Shares ($20,000.00/ $0.0008) multiplied by the Par Value of $0.001 ($25,000.00) minus the Conversion Amount of $20,000.00 plus $500.00 equals $5,500.00) .
