Stock”) at the option of the Holder, at any time and from time to time (subject to the conversion limitations set forth
in Section 4(c) hereof). The Holder shall effect conversions by delivering to the Company and Mount Tam a Notice of Conversion,
the form of which is attached hereto as Annex A (each, a “Notice of Conversion”), specifying therein
the principal amount of this Note to be converted and the date on which such conversion shall be effected (such date, the “Conversion
Date”). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such
Notice of Conversion is deemed delivered hereunder. To effect conversions hereunder, the Holder shall not be required to physically
surrender this Note to the Company unless the entire principal amount of this Note, plus all accrued and unpaid interest thereon,
has been so converted. Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Note in
an amount equal to the applicable conversion. The Holder and the Company shall maintain records showing the principal amount(s)
converted and the date of such conversion(s). The Company may deliver an objection to any Notice of Conversion within 1 Business
Day of delivery of such Notice of Conversion. In the event of any dispute or discrepancy, the records of the Holder shall be controlling
and determinative in the absence of manifest error. The Holder, and any assignee by acceptance of this Note, acknowledge and
agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and unconverted
principal amount of this Note may be less than the amount stated on the face hereof. For purposes of Section 4, references to
the Company shall include Mount Tam.


 


b)
Conversion Price. The conversion price in effect on any Conversion Date shall (subject to adjustment as required herein)
be equal to the lesser of (1) $1.50/share (subsequent to the Reverse Merger and the associated 100/1 reverse stock split); and
(2) the lowest of (i) a 30% discount to the 3 lowest closing prices of the Mount Tam Common Stock for the 10 days ending on the
day prior to the conversion notice, and (iii) a 30% discount to the three lowest closing prices of the Mount Tam Common Stock
for the 10 days ending on the thirtieth day subsequent to the reverse merger with Mount (collectively, the “Conversion
Price”).


 






    	 	-7-	 



    	 



    

 


c)
Conversion Limitations. The Company shall not effect any conversion of this Note, and a Holder shall not have the right
to convert any portion of this Note, to the extent that after giving effect to the conversion set forth on the applicable Notice
of Conversion, the Holder (together with the Holder’s Affiliates, and any other person or entity acting as a group together
with the Holder or any of the Holder’s Affiliates) would beneficially own in excess of the Beneficial Ownership Limitation
(as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder
and its Affiliates shall include the number of shares of Common Stock issuable upon conversion of this Note with respect to which
such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (A) conversion
of the remaining, unconverted principal amount of this Note beneficially owned by the Holder or any of its Affiliates and (B)
exercise or conversion of the unexercised or unconverted portion of any other securities of the Company subject to a limitation
on conversion or exercise analogous to the limitation contained herein (including, without limitation, any other Notes) beneficially
owned by the Holder or any of its Affiliates. Except as set forth in the preceding sentence, for purposes of this Section 4(c),
beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated
thereunder. To the extent that the limitation contained in this Section 4(c) applies, the determination of whether this Note is
convertible (in relation to other securities owned by the Holder together with any Affiliates) and of which principal amount of
this Note is convertible shall be in the sole discretion of the Holder, and the submission of a Notice of Conversion shall be
deemed to be the Holder’s determination of whether this Note may be converted (in relation to other securities owned by
the Holder together with any Affiliates) and which principal amount of this Note is convertible, in each case subject to the Beneficial
Ownership Limitation. To ensure compliance with this restriction, the Holder will be deemed to represent to the Company each time
it delivers a Notice of Conversion that such Notice of Conversion has not violated the restrictions set forth in this paragraph
and the Company shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination
as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the
rules and regulations promulgated thereunder. For purposes of this Section 4(c), in determining the number of outstanding shares
of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as stated in the most recent of the following:
(A) the Company’s most recent periodic or annual report, as the case may be; (B) a more recent public announcement by the
Company; or (C) a more recent notice by the Company or the Company’s or Mount Tam’s transfer agent setting forth the
number of shares of Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading
Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number
of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the
Company or Mount Tam, including this Note, by the Holder or its Affiliates since the date as of which such number of outstanding
shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of
shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon
conversion of this Note held by the Holder. The Holder, upon not less than 61 days’ prior notice to the Company and Mount
Tam, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 4(c), provided that the Beneficial
Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving
effect to the issuance of shares of Common Stock upon conversion of this Note held by the Holder and the Beneficial Ownership
Limitation provisions of this Section 4(c) shall continue to apply. Any such increase or decrease will not be effective until
the 61st day after such notice is delivered to the Company and Mount Tam. The Beneficial Ownership Limitation provisions
of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section
4(c) to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership
Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation.
The limitations contained in this paragraph shall apply to a successor holder of this Note.

to or as directed by the applicable Holder by the second Trading Day after the Conversion Date, the Holder shall be entitled to
elect by written notice to the Company at any time on or before its receipt of such certificate or certificates, to rescind such
Conversion, in which event the Company shall promptly return to the Holder any original Note delivered to the Company and the
Holder shall promptly return to Mount Tam the Common Stock certificates representing the principal amount of this Note unsuccessfully
tendered for conversion to the Company.


 


iv.
Obligation Absolute; Partial Liquidated Damages. The Company’s and Mount Tam’s obligations to issue and deliver
the Conversion Shares upon conversion of this Note in accordance with the terms hereof are absolute and unconditional, irrespective
of any action or inaction by the Holder to enforce the same, any waiver or consent with respect to any provision hereof, the recovery
of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment, limitation or termination,
or any breach or alleged breach by the Holder or any other Person of any obligation to the Company or any violation or alleged
violation of law by the Holder or any other Person, and irrespective of any other circumstance which might otherwise limit such
obligation of the Company or Mount Tam to the Holder in connection with the issuance of such Conversion Shares; provided,
however, that such delivery shall not operate as a waiver by the Company or Mount Tam of any such action the Company or
Mount Tam may have against the Holder. In the event the Holder of this Note shall elect to convert any or all of the outstanding
principal amount hereof, neither the Company nor Mount Tam may refuse conversion based on any claim that the Holder or anyone
associated or affiliated with the Holder has been engaged in any violation of law, agreement or for any other reason, unless an
injunction from a court, on notice to Holder, restraining and or enjoining conversion of all or part of this Note shall have been
sought and obtained, and the Company or Mount Tam posts a surety bond for the benefit of the Holder in the amount of 130% of the
outstanding principal amount of this Note, which is subject to the injunction, which bond shall remain in effect until the completion
of arbitration/litigation of the underlying dispute and the proceeds of which shall be payable to the Holder to the extent it
obtains judgment. In the absence of such injunction, the Company or Mount Tam shall issue Conversion Shares or, if applicable,
cash, upon a properly noticed conversion. If the Company or Mount Tam fails for any reason to deliver to the Holder such certificate
or certificates pursuant to Section 4(d)(ii) by the second Trading Day after the Conversion Date, the Company and Mount Tam shall
pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of principal amount being converted, $10
per Trading Day (increasing to $20 per Trading Day on the fifth (5th) Trading Day after such liquidated damages begin
to accrue) for each Trading Day after such second (2nd) Trading Day until such certificates are delivered. Nothing herein shall
limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section 8 hereof for the Company’s
or Mount Tam’s failure to deliver Conversion Shares within the period specified herein and the Holder shall have the right
to pursue all remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance
and/or injunctive relief. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant
to any other Section hereof or under applicable law.

v.
Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Conversion. In addition to any other rights available
to the Holder, if the Company fails for any reason to deliver to the Holder such certificate or certificates by the Share Delivery
Date pursuant to Section 4(d)(ii), and if after such Share Delivery Date the Holder is required by its brokerage firm to purchase
(in an open market transaction or otherwise), or the Holder’s brokerage firm otherwise purchases, shares of Common Stock
to deliver in satisfaction of a sale by the Holder of the Conversion Shares which the Holder was entitled to receive upon the
conversion relating to such Share Delivery Date (a “Buy-In”), then the Company and Mount Tam shall (A) pay
in cash to the Holder (in addition to any other remedies available to or elected by the Holder) the amount by which (x) the Holder’s
total purchase price (including any brokerage commissions) for the Common Stock so purchased exceeds (y) the product of (1) the
aggregate number of shares of Common Stock that the Holder was entitled to receive from the conversion at issue multiplied by
(2) the actual sale price at which the sell order giving rise to such purchase obligation was executed (including any brokerage
commissions) and (B) at the option of the Holder, either reissue (if surrendered) this Note in a principal amount equal to the
principal amount of the attempted conversion or deliver to the Holder the number of shares of Common Stock that would have been
issued if the Company and Mount Tam had timely complied with its delivery requirements under Section 4(d)(ii). For example, if
the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion
of this Note with respect to which the actual sale price of the Conversion Shares (including any brokerage commissions) giving
rise to such purchase obligation was a total of $10,000 under clause (A) of the immediately preceding sentence, the Company and
Mount Tam shall be required to pay the Holder $1,000. The Holder shall provide the Company and Mount Tam written notice indicating
the amounts payable to the Holder in respect of the Buy-In and, upon request of the Company and Mount Tam, evidence of the amount
of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law
or in equity including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s
and Mount Tam’s failure to timely deliver certificates representing shares of Common Stock upon conversion of this Note
as required pursuant to the terms hereof.


 


vi.
Reservation of Shares Issuable Upon Conversion. The Company and Mount Tam each covenants that it will at all times reserve
and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion
of this Note, as herein provided, free from preemptive rights or any other actual contingent purchase rights of Persons other
than the Holder (and the other holders of the Notes), not less than five times such aggregate number of shares of the Common Stock
as shall (subject to the terms and conditions set forth in the Purchase Agreement) be issuable (taking into account the adjustments
and restrictions of Section 5) upon the conversion of the outstanding principal amount of this Note and payment of interest hereunder.
The Company and Mount Tam each covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly
authorized, validly issued, fully paid and nonassessable and, if the Registration Statement is then effective under the Securities
Act, shall be registered for public sale in accordance with such Registration Statement.


 


vii.
Fractional Shares. No fractional shares or scrip representing fractional shares shall be issued upon the conversion of
this Note. As to any fraction of a share which Holder would otherwise be entitled to purchase upon such conversion, the Company
and Mount Tam shall at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such
fraction multiplied by the Conversion Price or round up to the next whole share.


 






    	 	-10-	 



    	 



    

 


viii.
Transfer Taxes. The issuance of certificates for shares of the Common Stock on conversion of this Note shall be made without
charge to the Holder hereof for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery
of such certificates, provided that, the Company and Mount Tam shall not be required to pay any tax that may be payable in respect
of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the
Holder of this Note so converted and the Company and Mount Tam shall not be required to issue or deliver such certificates unless
or until the person or persons requesting the issuance thereof shall have paid to the Company and Mount Tam the amount of such
tax or shall have established to the satisfaction of the Company and Mount Tam that such tax has been paid.


 


Section
5. Certain Adjustments.


 


a)
Stock Dividends and Stock Splits. If the Company or Mount Tam, at any time while this Note is outstanding: (i) pays a stock
dividend or otherwise makes a distribution or distributions payable in shares of Common Stock on shares of Common Stock or any
Common Stock Equivalents (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon
conversion of, or payment of interest on, the Notes), (ii) subdivides outstanding shares of Common Stock into a larger number
of shares, (iii) combines (including by way of a reverse stock split) outstanding shares of Common Stock into a smaller number
of shares or (iv) issues, in the event of a reclassification of shares of the Common Stock, any shares of capital stock of the
Company, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common
Stock (excluding any treasury shares of the Company or Mount Tam) outstanding immediately before such event and of which the denominator
shall be the number of shares of Common Stock outstanding immediately after such event. Any adjustment made pursuant to this Section
shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend
or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.
For purposes of Section 5, references to the Company shall include Mount Tam.


 


b)
Subsequent Equity Sales. If, at any time while this Note is outstanding, the Company or any Subsidiary or Mount Tam, as
applicable, sells or grants any option to purchase or sells or grants any right to reprice, or otherwise disposes of or issues
(or announces any sale, grant or any option to purchase or other disposition), any common stock or common stock equivalents entitling
any Person to acquire shares of common stock at an effective price per share that is lower than the then Conversion Price (such
lower price, the “Base Conversion Price” and such issuances, collectively, a “Dilutive Issuance”)
(if the holder of the common stock or common stock equivalents 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 issuance, be entitled to receive shares of common stock at an effective price
per share that is lower than the Conversion Price, such issuance shall be deemed to have occurred for less than the Conversion
Price on such date of the Dilutive Issuance), then the Conversion Price shall be reduced to equal the Base Conversion Price. Such
adjustment shall be made whenever such common stock or common stock equivalents are issued. Notwithstanding the foregoing, no
adjustment will be made under this Section 5(b) in respect of an Exempt Issuance. If the Company or Mount Tam enters into a Variable
Rate Transaction, despite the prohibition set forth in the Purchase Agreement, the Company shall be deemed to have issued common
stock or common stock equivalents at the lowest possible conversion price at which such securities may be converted or exercised.
The Company and Moount Tam shall notify the Holder in writing, no later than 1 Business Day following the issuance of any Common
Stock or Common Stock Equivalents subject to this Section 5(b), indicating therein the applicable issuance price, or applicable
reset price, exchange price, conversion price and other pricing terms (such notice, the “Dilutive Issuance Notice”).
For purposes of clarification, whether or not the Company or Mount Tam provides a Dilutive Issuance Notice pursuant to this Section
5(b), upon the occurrence of any Dilutive Issuance, the Holder is entitled to receive a number of Conversion Shares based upon
the Base Conversion Price on or after the date of such Dilutive Issuance, regardless of whether the Holder accurately refers to
the Base Conversion Price in the Notice of Conversion.


 






    	 	-11-	 



    	 



    

 


c)
Subsequent Rights Offerings. If the Company or Mount Tam, at any time while the Note is outstanding, shall issue rights,
options or warrants to all holders of Common Stock (and not to Holders) entitling them to subscribe for or purchase shares of
Common Stock at a price per share that is lower than the VWAP on the record date referenced below, then the Conversion Price shall
be multiplied by a fraction of which the denominator shall be the number of shares of the Common Stock outstanding on the date
of issuance of such rights or warrants plus the number of additional shares of Common Stock offered for subscription or purchase,
and of which the numerator shall be the number of shares of the Common Stock outstanding on the date of issuance of such rights
or warrants plus the number of shares which the aggregate offering price of the total number of shares so offered (assuming delivery
to the Company or Mount Tam in full of all consideration payable upon exercise of such rights, options or warrants) would purchase
at such VWAP. Such adjustment shall be made whenever such rights or warrants are issued, and shall become effective immediately
after the record date for the determination of stockholders entitled to receive such rights, options or warrants.


 


d)
Pro Rata Distributions. If the Company or Mount Tam, at any time while this Note is outstanding, distributes to all holders
of Common Stock (and not to the Holders) evidences of its indebtedness or assets (including cash and cash dividends) or rights
or warrants to subscribe for or purchase any security (other than the Common Stock, which shall be subject to Section 5(b)), then
in each such case the Conversion Price shall be adjusted by multiplying such Conversion Price in effect immediately prior to the
record date fixed for determination of stockholders entitled to receive such distribution by a fraction of which the denominator
shall be the VWAP determined as of the record date mentioned above, and of which the numerator shall be such VWAP on such record
date less the then fair market value at such record date of the portion of such assets or evidence of indebtedness so distributed
applicable to 1 outstanding share of the Common Stock as determined by the Board of Directors of the Company or Mount Tam in good
faith. In either case the adjustments shall be described in a statement delivered to the Holder describing the portion of assets
or evidences of indebtedness so distributed or such subscription rights applicable to 1 share of Common Stock. Such adjustment
shall be made whenever any such distribution is made and shall become effective immediately after the record date mentioned above.


 


e)
Fundamental Transaction. If, at any time while this Note is outstanding, (i) the Company or Mount Tam effects any merger
or consolidation of the Company or Mount Tam with or into another Person, (ii) the Company or Mount Tam effects any sale of all
or substantially all of its assets in one transaction or a series of related transactions, (iii) any tender offer or exchange
offer (whether by the Company or Mount Tam or another Person) is completed pursuant to which holders of Common Stock are permitted
to tender or exchange their shares for other securities, cash or property, or (iv) the Company or Mount Tam effects any reclassification
of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged
for other securities, cash or property (in any such case, a “Fundamental Transaction”), then, upon any subsequent
conversion of this Note, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon
such conversion immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount of securities, cash
or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately
prior to such Fundamental Transaction, the holder of 1 share of Common Stock (the “Alternate Consideration”).
For purposes of any such conversion, the determination of the Conversion Price shall be appropriately adjusted to apply to such
Alternate Consideration based on the amount of Alternate Consideration issuable in respect of 1 share of Common Stock in such
Fundamental Transaction, and the Company shall apportion the Conversion Price among the Alternate Consideration in a reasonable
manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are
given any choice as to the securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be
given the same choice as to the Alternate Consideration it receives upon any conversion of this Note following such Fundamental
Transaction. To the extent necessary to effectuate the foregoing provisions, any successor to the Company or surviving entity
in such Fundamental Transaction shall issue to the Holder a new Note consistent with the foregoing provisions and evidencing the
Holder’s right to convert such Note into Alternate Consideration. The terms of any agreement pursuant to which a Fundamental
Transaction is effected shall include terms requiring any such successor or surviving entity to comply with the provisions of
this Section 5(e) and insuring that this Note (or any such replacement security) will be similarly adjusted upon any subsequent
transaction analogous to a Fundamental Transaction.

f)
Calculations. All calculations under this Section 5 shall be made to the nearest cent or the nearest 1/100th of a share,
as the case may be. For purposes of this Section 5, the number of shares of Common Stock deemed to be issued and outstanding as
of a given date shall be the sum of the number of shares of Common Stock (excluding any treasury shares of the Company or Mount
Tam) issued and outstanding.


 


g)
Notice to the Holder.


 


i.
Adjustment to Conversion Price. Whenever the Conversion Price is adjusted pursuant to any provision of this Section 5,
the Company and Mount Tam shall promptly deliver to each Holder a notice setting forth the Conversion Price after such adjustment
and setting forth a brief statement of the facts requiring such adjustment.


 


ii.
Notice to Allow Conversion by Holder. If (A) the Company or Mount Tam shall declare a dividend (or any other distribution
in whatever form) on the Common Stock, (B) the Company or Mount Tam shall declare a special nonrecurring cash dividend on or a
redemption of the Common Stock, (C) the Company or Mount Tam shall authorize the granting to all holders of the Common Stock of
rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of
any stockholders of the Company or Mount Tam shall be required in connection with any reclassification of the Common Stock, any
consolidation or merger to which the Company or Mount Tam is a party, any sale or transfer of all or substantially all of the
assets of the Company or Mount Tam, of any compulsory share exchange whereby the Common Stock is converted into other securities,
cash or property or (E) the Company or Mount Tam shall authorize the voluntary or involuntary dissolution, liquidation or winding
up of the affairs of the Company or Mount Tam, then, in each case, the Company or Mount Tam shall cause to be filed at each office
or agency maintained for the purpose of conversion of this Note, and shall cause to be delivered to the Holder at its last address
as it shall appear upon the Note Register, at least twenty (20) calendar days prior to the applicable record or effective date
hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution,
redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record
to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such
reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date
as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common
Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or
share exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect
the validity of the corporate action required to be specified in such notice. The Holder is entitled to convert this Note during
the 20-day period commencing on the date of such notice through the effective date of the event triggering such notice.

Section
6. Redemption; Automatic Conversion.


 


a)
Optional Redemption at Election of Company. Subject to the provisions of this Section 6(a), at any time after Original
Issue Date, the Company may, deliver a written notice to the Holder (an “Optional Redemption Notice” and the
date such notice is deemed delivered hereunder, the “Optional Redemption Notice Date”) of its irrevocable election
to redeem all of the then outstanding principal amount of this Note for cash in an amount equal to the Optional Redemption Amount
on the 20th Trading Day following the Optional Redemption Notice Date (such date, the “Optional Redemption
Date”, such 20 Trading Day period, the “Optional Redemption Period” and such redemption, the “Optional
Redemption”). The Optional Redemption Amount is payable in full on the Optional Redemption Date. The Company and Mount
Tam covenant and agrees that it will honor all Notices of Conversion tendered from the time of delivery of the Optional Redemption
Notice through the date all amounts owing thereon are due and paid in full. The Company’s determination to pay an Optional
Redemption in cash shall be applied ratably to all of the holders of the then outstanding Notes based on their (or their predecessor’s)
initial purchases of Notes pursuant to the Purchase Agreement. In the event of any such attempt to repay the Notes, the Holder
shall have the right to convert the Notes prior to the date of any such prepayment in accordance with the conversion mechanics
set forth herein.


 


b)
Monthly Redemption. On each Monthly Redemption Date, the Company shall redeem the Monthly Redemption Amount (the “Monthly
Redemption”). The Monthly Redemption Amount payable on each Monthly Redemption Date shall be paid in cash or, subject
to the Equity Conditions (as described below) in freely tradable shares of Common Stock (pursuant to Rule 144 or otherwise) at
a 25% discount to the 3 lowest closing prices in the 20 trading days prior to the Monthly Redemption Date. Upon the agreement
of the Company and the Holder, the amortizations may be accelerated. The Company shall require Investors’ consent to issue
more than 15% of the Company’s or Mount Tam’s trading volume in common stock a given month. Holder may convert, pursuant
to Section 4(a), any principal amount of this Note subject to a Monthly Redemption at any time prior to the date that the Monthly
Redemption Amount, plus accrued but unpaid interest, liquidated damages and any other amounts then owing to the Holder are due
and paid in full. Any principal amount of this Note converted during the applicable Monthly Conversion Period in excess of the
Monthly Redemption Amount shall be applied against the last principal amount of this Note scheduled to be redeemed hereunder,
in reverse time order from the Maturity Date. The Company and Mount Tam covenants and agrees that it will honor all Notices of
Conversion tendered up until such amounts are paid in full. The Company’s determination to pay a Monthly Redemption shall
be applied ratably to all of the holders of the then outstanding Notes based on their (or their predecessor’s) initial purchases
of Notes pursuant to the Purchase Agreement.


 


c)
Redemption Procedure. The payment of cash or Common Stock pursuant to an Optional Redemption or a Monthly Redemption shall
be payable on the Optional Redemption Date and Monthly Redemption Date, as applicable. If any portion of the payment pursuant
to an Optional Redemption or Monthly Redemption shall not be paid by the Company by the applicable due date, interest shall accrue
thereon at an interest rate equal to the lesser of 18% per annum or the maximum rate permitted by applicable law until such amount
is paid in full. Notwithstanding anything herein contained to the contrary, if any portion of the Optional Redemption Amount or
Monthly Redemption Amount remains unpaid after such date, the Holder may elect, by written notice to the Company given at any
time thereafter, to invalidate such Optional Redemption or Monthly Redemption, ab initio, and, with respect to the Company’s
failure to honor the Optional Redemption, the Company shall have no further right to exercise such Optional Redemption. Notwithstanding
anything to the contrary in this Section 6, the Company’s determination to redeem in cash or its elections under Section
6(b) shall be applied ratably among the Holders of Notes. The Holder may elect to convert the outstanding principal amount of
the Note pursuant to Section 4 prior to actual payment in cash for any redemption under this Section 6 by the delivery of a Notice
of Conversion to the Company.


 


d)
Fractional Shares. No fractional shares are to be issued upon the conversion of this Note, but rather the number of shares
of Common Stock to be issued shall be rounded to the nearest whole number. To the extent that rounding up to the nearest whole
number would result in a violation of Section 4(d)(vi), the Company shall pay the applicable converting Holder an amount in cash
equal to the fractional share amount multiplied by the Closing Bid Price for the Common Stock on the such date of conversion.


 






    	 	-14-	 



    	 



    

 


e)
Most Favored Nation. During the term of the Note, if the Company or Mount Tam engages in any future financing transactions
with a third party investor, the Company and Mount Tam will provide the Holder with written notice (the “MFN Notice”)
thereof promptly but in no event less than 10 days prior to closing any financing transactions. Included with the MFN Notice shall
be a copy of all documentation relating to such financing transaction and shall include, upon written request of the Holder, any
additional information related to such subsequent investment as may be reasonably requested by the Holder. In the event the Holder
determines that the terms of the subsequent investment are preferable to the terms of the Securities of the Company issued to
the Holder pursuant to the terms of the Purchase Agreement, the Holder will notify the Company in writing. Promptly after receipt
of such written notice from the Holder, the Company and Mount Tam agrees to amend and restate the Securities, and, as necessary,
adjust the number of bonus shares, to be identical to the instruments evidencing the subsequent investment and any bonus shares
issued in connection therewith.


 


f)
Mandatory Prepayment. The Company shall be required to offer to prepay in cash the aggregate principal amount of the Notes
at 120% of the principal amount thereof plus any unpaid accrued interest to the prepayment date, (i) on the sale of assets of
the Company or its Subsidiaries or Mount Tam, or (ii) upon a Change of Control Transaction, or (iii) on a Qualified Offering of
the Company or Mount Tam. In such an event, the Investor(s) shall have the right to convert the Notes prior to the date of any
such prepayment in accordance with any of the conversion mechanics as set forth herein.


 


Section
7. Negative Covenants. As long as any portion of this Note remains outstanding, unless the holders of at least 67%
in principal amount of the then outstanding Notes shall have otherwise given prior written consent, the Company shall not, and
shall not permit any of its subsidiaries (whether or not a Subsidiary on the Original Issue Date) to, directly or indirectly:


 


a)
other than Permitted Indebtedness, enter into, create, incur, assume, guarantee or suffer to exist any indebtedness for borrowed
money of any kind, including, but not limited to, a guarantee, on or with respect to any of its property or assets now owned or
hereafter acquired or any interest therein or any income or profits therefrom;

Tam or the Company departing officers and directors of the Company, provided that such repurchases shall not exceed an aggregate
of $50,000 for all officers and directors during the term of this Note;


 


e)
repay, repurchase or offer to repay, repurchase or otherwise acquire, or pay any interest on any Indebtedness, other than the
Notes if on a pro-rata basis, other than regularly scheduled interest payments of the equipment loans and specified merchant cash
advances as such instruments are in effect as of the Original Issue Date, provided that such payments shall not be permitted if,
at such time, or after giving effect to such payment, any Event of Default exist or occur;

f)

h)
enter into any agreement with respect to any of the foregoing.


 


Section
8. Events of Default.


 


a)
“Event of Default” means, wherever used herein, any of the following events (whatever the reason for such event

viii.
the Company or Mount Tam shall be a party to any Change of Control Transaction or Fundamental Transaction or shall agree to sell

and Mount Tam shall be permitted an additional 10 consecutive Trading Days during any 12 month period pursuant to this Section

xiii.
any monetary judgment, writ or similar final process shall be entered or filed against the Company, any subsidiary, Mount Tam
or any of their respective property or other assets for more than $50,000, and such judgment, writ or similar final process shall
remain unvacated, unbonded or unstayed for a period of 45 calendar days.


 


b)
Remedies Upon Event of Default. If any Event of Default occurs, the outstanding principal amount of this Note, plus accrued
but unpaid interest, liquidated damages and other amounts owing in respect thereof through the date of acceleration, shall become,
at the Holder’s election, immediately due and payable in cash at the Mandatory Default Amount. Commencing 5 days after the
occurrence of any Event of Default that results in the eventual acceleration of this Note, the interest rate on this Note shall
accrue at an interest rate equal to the lesser of 18% per annum or the maximum rate permitted under applicable law. At Holder’s
option, it shall be entitled to be paid in cash or from time to time in common stock with the conversion price of the common stock
equal to a 30% discount to the average of the three lowest closing prices of the common stock for the 20 prior trading days. Upon
the payment in full of the Mandatory Default Amount, the Holder shall promptly surrender this Note to or as directed by the Company.
In connection with such acceleration described herein, the Holder need not provide, and the Company hereby waives, any presentment,
demand, protest or other notice of any kind, and the Holder 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 Holder at any time prior to payment hereunder and the Holder shall have all rights as a holder
of the Note until such time, if any, as the Holder receives full payment pursuant to this Section 8(b). No such rescission or
annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

withheld or delayed) and (ii) issue to the Holder a new Note of such successor entity evidenced by a written instrument substantially
similar in form and substance to this Note, including, without limitation, having a principal amount and interest rate equal to
the principal amount and the interest rate of this Note and having similar ranking to this Note, which shall be satisfactory to
the Holder (any such approval not to be unreasonably withheld or delayed). The provisions of this Section 9(i) shall apply similarly
and equally to successive Fundamental Transactions and shall be applied without regard to any limitations of this Note.
