CONVERTIBLE
PROMISSORY NOTE

 

FOR
VALUE RECEIVED, ADAMAS ONE CORP., a Nevada corporation (hereinafter called the “Borrower”), hereby promises to
pay to the order of Glenn Preslier, an individual, or registered assigns (the “Holder”) the sum of $250,000.00 USD
together with any interest as set forth herein, on July 31, 2022 (the “Maturity Date”), and to pay interest on the unpaid
principal balance hereof at the rate of eight percent (8%) (the “Interest Rate”) per annum from the date hereof (the “Issue
Date”) until the same becomes due and payable, whether at maturity or upon acceleration or by prepayment or otherwise. This Note
may not be prepaid in whole or in part except as otherwise explicitly set forth herein with the written consent of the Holder which may
be withheld for any reason or for no reason. All payments due hereunder (to the extent not converted into common stock, $0.001 par value
per share (the “Common Stock”) in accordance with the terms hereof) shall be made in lawful money of the United States of
America. All payments shall be made at such address as the Holder shall hereafter give to the Borrower by written notice made in accordance
with the provisions of this Note. Whenever any amount expressed to be due by the terms of this Note is due on any day which is not a
business day, the same shall instead be due on the next succeeding day which is a business day and, in the case of any interest payment
date which is not the date on which this Note is paid in full, the extension of the due date thereof shall not be taken into account
for purposes of determining the amount of interest due on such date. As used in this Note, the term “business day” shall
mean any day other than a Saturday, Sunday or a day on which commercial banks in the city of New York, New York are authorized or required
by law or executive order to remain closed. Each capitalized term used herein, and not otherwise defined, shall have the meaning ascribed
thereto in that certain Securities Purchase Agreement dated the date hereof, pursuant to which this Note was originally issued (the “Purchase
Agreement”).

     

     

    

This
Note is free from all taxes, liens, claims and encumbrances with respect to the issue thereof and shall not be subject to preemptive
rights or other similar rights of shareholders of the Borrower and will not impose personal liability upon the holder thereof.

 

The
following terms shall apply to this Note:

 

Article
I. CONVERSION RIGHTS

 

1.1 Conversion
Right. The Holder shall have the right at any time after the date of this Note and ending on the later of (i) the Maturity Date
and (ii) the date of payment of the Default Amount (as defined in Article III) pursuant to Section 1.6(a) or Article III, each in
respect of the remaining outstanding principal amount of this Note to convert all or any part of the outstanding and unpaid
principal amount of this Note into fully paid and non-assessable shares of Common Stock, as such Common Stock exists on the Issue
Date, or any shares of capital stock or other securities of the Borrower into which such Common Stock shall hereafter be changed or
reclassified at the Conversion Price (as defined below) determined as provided herein (a “Conversion”); provided, however,
that in no event shall the Holder be entitled to convert any portion of this Note in excess of that portion of this Note upon
conversion of which the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other
than shares of Common Stock which may be deemed beneficially owned through the ownership of the unconverted portion of the Notes or
the unexercised or unconverted portion of any other security of the Borrower subject to a limitation on conversion or exercise
analogous to the limitations contained herein) and (2) the number of shares of Common Stock issuable upon the conversion of the
portion of this Note with respect to which the determination of this proviso is being made, would result in beneficial ownership by
the Holder and its affiliates of more than 9.99% of the outstanding shares of Common Stock. For purposes of the proviso to the
immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange
Act of 1934, as amended (the “Exchange Act”), and Regulations 13D-G thereunder, except as otherwise provided in clause
(1) of such proviso, provided, further, however, that the limitations on conversion may be waived by the Holder
upon, at the election of the Holder, not less than 61 days’ prior notice to the Borrower, and the provisions of the conversion
limitation shall continue to apply until such 61st day (or such later date, as determined by the Holder, as may be specified in such
notice of waiver). The number of shares of Common Stock to be issued upon each conversion of this Note shall be determined by
dividing the Conversion Amount (as defined below) by the applicable Conversion Price then in effect on the date specified in the
notice of conversion, in the form attached hereto as Exhibit A (the “Notice of Conversion”), delivered to the Borrower
by the Holder in accordance with Section 1.4 below; provided that the Notice of Conversion is submitted by facsimile or e-mail (or
by other means resulting in, or reasonably expected to result in, notice) to the Borrower before 6:00 p.m., New York, New York time
on such conversion date (the “Conversion Date”). The term “Conversion Amount” means, with respect to any
conversion of this Note, the sum of (1) the principal amount of this Note to be converted in such conversion plus (2) at the
Holder’s option, accrued and unpaid interest, if any, on such principal amount at the interest rates provided in this Note to
the Conversion Date, provided however, that the Borrower shall have the right to pay any or all interest in cash plus (3) at
the Holder’s option, Default Interest, if any, on the amounts referred to in the immediately preceding clauses (1) and/or (2) plus
(4) at the Holder’s option, any amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof.

    2

     

    

1.2 Conversion
Price.

 

(a) Calculation
of Conversion Price. The conversion price (the “Conversion Price”) shall be equal to $4.00 per share.

 

1.3 Authorized
Shares. The Borrower covenants that during the period the conversion right exists, the Borrower will reserve from its authorized
and unissued Common Stock a sufficient number of shares, free from preemptive rights, to provide for the issuance of Common Stock upon
the full conversion of this Note issued pursuant to the Purchase Agreement. The Borrower is required at all times to have authorized
and reserved seven times the number of shares that is actually issuable upon full conversion of the Note (based on the Conversion Price
of the Notes in effect from time to time) (the “Reserved Amount”). The Reserved Amount shall be increased from time to time
in accordance with the Borrower’s obligations pursuant to Section 3(d) of the Purchase Agreement. The Borrower represents that
upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. In addition, if the Borrower shall issue any
securities or make any change to its capital structure which would change the number of shares of Common Stock into which the Notes shall
be convertible at the then current Conversion Price, the Borrower shall at the same time make proper provision so that thereafter there
shall be a sufficient number of shares of Common Stock authorized and reserved, free from preemptive rights, for conversion of the outstanding
Notes.

 

1.4 Method
of Conversion.

 

(a) Mechanics
of Conversion. Subject to Section 1.1, this Note may be converted by the Holder in whole or in part at any time from time to time
after the Issue Date, by (A) submitting to the Borrower a Notice of Conversion (by facsimile, e-mail or other reasonable means of
communication dispatched on the Conversion Date prior to 5:00 p.m., New York, New York time) and (B) subject to Section 1.4(b),
surrendering this Note at the principal office of the Borrower.

 

(b) Surrender
of Note Upon Conversion. Notwithstanding anything to the contrary set forth herein, upon conversion of this Note in accordance with
the terms hereof, the Holder shall not be required to physically surrender this Note to the Borrower unless the entire unpaid principal
amount of this Note is so converted. The Holder and the Borrower shall maintain records showing the principal amount so converted and
the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Borrower, so as not to require
physical surrender of this Note upon each such conversion. In the event of any dispute or discrepancy, such records of the Borrower shall,
prima facie, be controlling and determinative in the absence of manifest error. Notwithstanding the foregoing, if any portion
of this Note is converted as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders this Note
to the Borrower, whereupon the Borrower will forthwith issue and deliver upon the order of the Holder a new Note of like tenor, registered
as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, representing in the aggregate the remaining
unpaid principal amount of this Note. 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 represented by this Note may be less than the amount stated on the face hereof.

    3

     

    

(c) Payment
of Taxes. The Borrower shall not be required to pay any tax which may be payable in respect of any transfer involved in the issue
and delivery of shares of Common Stock or other securities or property on conversion of this Note in a name other than that of the Holder
(or in street name), and the Borrower shall not be required to issue or deliver any such shares or other securities or property unless
and until the person or persons (other than the Holder or the custodian in whose street name such shares are to be held for the Holder’s
account) requesting the issuance thereof shall have paid to the Borrower the amount of any such tax or shall have established to the
satisfaction of the Borrower that such tax has been paid.

 

(d) Delivery
of Common Stock Upon Conversion. Upon receipt by the Borrower from the Holder of a facsimile transmission or e-mail (or other reasonable
means of communication) of a Notice of Conversion meeting the requirements for conversion as provided in this Section 1.4, the Borrower
shall issue and deliver or cause to be issued and delivered to or upon the order of the Holder certificates for the Common Stock issuable
upon such conversion within three (3) business days after such receipt (the “Deadline”) (and, solely in the case of conversion
of the entire unpaid principal amount hereof, surrender of this Note) in accordance with the terms hereof and the Purchase Agreement.

 

(e) Obligation
of Borrower to Deliver Common Stock. Upon receipt by the Borrower of a Notice of Conversion, the Holder shall be deemed to be the
holder of record of the Common Stock issuable upon such conversion, the outstanding principal amount and the amount of accrued and unpaid
interest on this Note shall be reduced to reflect such conversion, and, unless the Borrower defaults on its obligations under this Article
I, all rights with respect to the portion of this Note being so converted shall forthwith terminate except the right to receive the Common
Stock or other securities, cash or other assets, as herein provided, on such conversion. If the Holder shall have given a Notice of Conversion
as provided herein, the Borrower’s obligation to issue and deliver the certificates for Common Stock shall be absolute and unconditional,
irrespective of the absence of any action by the Holder to enforce the same, any waiver or consent with respect to any provision thereof,
the recovery of any judgment against any person or any action to enforce the same, any failure or delay in the enforcement of any other
obligation of the Borrower to the holder of record, or any setoff, counterclaim, recoupment, limitation or termination, or any breach
or alleged breach by the Holder of any obligation to the Borrower, and irrespective of any other circumstance which might otherwise limit
such obligation of the Borrower to the Holder in connection with such conversion. The Conversion Date specified in the Notice of Conversion
shall be the Conversion Date so long as the Notice of Conversion is received by the Borrower before 5:00 p.m., New York, New York time,
on such date.

 

(f) Delivery
of Common Stock by Electronic Transfer. In lieu of delivering physical certificates representing the Common Stock issuable upon conversion,
provided the Borrower is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”)
program, upon request of the Holder and its compliance with the provisions contained in Section 1.1 and in this Section 1.4, the Borrower
shall use its commercially reasonable best efforts to cause its transfer agent to electronically transmit the Common Stock issuable upon
conversion to the Holder by crediting the account of Holder’s Prime Broker with DTC through its Deposit Withdrawal At Custodian
(“DWAC”) system.

    4

     

    

1.5 Concerning
the Shares. The shares of Common Stock issuable upon conversion of this Note may not be sold or transferred unless (i) such shares
are sold pursuant to an effective registration statement under the Act or (ii) the Borrower or its transfer agent shall have been furnished
with an opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions)
to the effect that the shares to be sold or transferred may be sold or transferred pursuant to an exemption from such registration or
(iii) such shares are sold or transferred pursuant to Rule 144 under the Act (or a successor rule) (“Rule 144”) or (iv)
such shares are transferred to an “affiliate” (as defined in Rule 144) of the Borrower who agrees to sell or otherwise transfer
the shares only in accordance with this Section 1.5 and who is an Accredited Investor (as defined in the Purchase Agreement). Except
as otherwise provided in the Purchase Agreement (and subject to the removal provisions set forth below), until such time as the shares
of Common Stock issuable upon conversion of this Note have been registered under the Act or otherwise may be sold pursuant to Rule 144
without any restriction as to the number of securities as of a particular date that can then be immediately sold, each certificate for
shares of Common Stock issuable upon conversion of this Note that has not been so included in an effective registration statement or
that has not been sold pursuant to an effective registration statement or an exemption that permits removal of the legend, shall bear
a legend substantially in the following form, as appropriate:

 

“NEITHER
THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE EXERCISABLE
HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED
FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL (WHICH COUNSEL SHALL BE SELECTED BY THE HOLDER), IN A GENERALLY ACCEPTABLE FORM,
THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT. NOTWITHSTANDING
THE FOREGOING, THE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT OR OTHER LOAN OR FINANCING ARRANGEMENT SECURED
BY THE SECURITIES.”

 

The
legend set forth above shall be removed and the Borrower shall issue to the Holder a new certificate therefore free of any transfer legend
if (i) the Borrower or its transfer agent shall have received an opinion of counsel, in form, substance and scope customary for opinions
of counsel in comparable transactions, to the effect that a public sale or transfer of such Common Stock may be made without registration
under the Act, which opinion shall be reasonably accepted by the Borrower so that the sale or transfer is effected or (ii) in the case
of the Common Stock issuable upon conversion of this Note, such security is registered for sale by the Holder under an effective registration
statement filed under the Act or otherwise may be sold pursuant to Rule 144 without any restriction as to the number of securities as
of a particular date that can then be immediately sold. In the event that the Borrower does not accept the opinion of counsel provided
by the Buyer with respect to the transfer of Securities pursuant to an exemption from registration, such as Rule 144 or Regulation S,
at the Deadline, it will be considered an Event of Default pursuant to Section 3.2 of the Note.

    5

     

    

Article
II. CERTAIN COVENANTS

 

2.1 Sale
of Assets. So long as the Borrower shall have any obligation under this Note, the Borrower shall not, without the Holder’s
written consent, sell, lease or otherwise dispose of any significant portion of its assets outside the ordinary course of business. Any
consent to the disposition of any assets may be conditioned on a specified use of the proceeds of disposition.

 

2.2 Preservation
of Existence, etc. The Borrower shall maintain and preserve, and cause each of its Subsidiaries to maintain and preserve, its existence,
rights and privileges, and become or remain, and cause each of its Subsidiaries (other than dormant Subsidiaries that have no or minimum
assets) to become or remain, duly qualified and in good standing in each jurisdiction in which the character of the properties owned
or leased by it or in which the transaction of its business makes such qualification necessary.

 

2.3 Non-circumvention.
The Borrower hereby covenants and agrees that the Borrower will not, by amendment of its Certificate or Articles of Incorporation or
Bylaws, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of
securities, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Note, and
will at all times in good faith carry out all the provisions of this Note and take all action as may be required to protect the rights
of the Holder.

 

Article
III. EVENTS OF DEFAULT

 

If
any of the following events of default (each, an “Event of Default”) shall occur:

 

3.1 Conversion
and the Shares. The Borrower fails to issue shares of Common Stock to the Holder (or announces or threatens in writing that it will
not honor its obligation to do so) upon exercise by the Holder of the conversion rights of the Holder in accordance with the terms of
this Note, fails to transfer or cause its transfer agent to transfer (issue) (electronically or in certificated form) any certificate
for shares of Common Stock issued to the Holder upon conversion of or otherwise pursuant to this Note as and when required by this Note,
the Borrower directs its transfer agent not to transfer or delays, impairs, and/or hinders its transfer agent in transferring (or issuing)
(electronically or in certificated form) any certificate for shares of Common Stock to be issued to the Holder upon conversion of or
otherwise pursuant to this Note as and when required by this Note, or fails to remove (or directs its transfer agent not to remove or
impairs, delays, and/or hinders its transfer agent from removing) any restrictive legend (or to withdraw any stop transfer instructions
in respect thereof) on any certificate for any shares of Common Stock issued to the Holder upon conversion of or otherwise pursuant to
this Note as and when required by this Note (or makes any written announcement, statement or threat that it does not intend to honor
the obligations described in this paragraph) and any such failure shall continue uncured (or any written announcement, statement or threat
not to honor its obligations shall not be rescinded in writing) for three (3) business days after the Holder shall have delivered a Notice
of Conversion. It is an obligation of the Borrower to remain current in its obligations to its transfer agent. It shall be an event of
default of this Note, if a conversion of this Note is delayed, hindered or frustrated due to a balance owed by the Borrower to its transfer
agent. If at the option of the Holder, the Holder advances any funds to the Borrower’s transfer agent in order to process a conversion,
such advanced funds shall be paid by the Borrower to the Holder within forty-eight (48) hours of a demand from the Holder.

    6

     

    

3.2 Breach
of Covenants. The Borrower breaches any material covenant or other material term or condition contained in this Note and any collateral
documents including but not limited to the Purchase Agreement and such breach continues for a period of ten (10) days after written notice
thereof to the Borrower from the Holder.

 

3.3 Breach
of Representations and Warranties. Any representation or warranty of the Borrower made herein or in any agreement, statement or certificate
given in writing pursuant hereto or in connection herewith (including, without limitation, the Purchase Agreement), shall be false or
misleading in any material respect when made and the breach of which has (or with the passage of time will have) a material adverse effect
on the rights of the Holder with respect to this Note or the Purchase Agreement.

 

Article
IV. MISCELLANEOUS

 

4.1 Failure
or Indulgence Not Waiver. No failure or delay on the part of the Holder in the exercise of any power, right or privilege hereunder
shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further
exercise thereof or of any other right, power or privileges. All rights and remedies existing hereunder are cumulative to, and not exclusive
of, any rights or remedies otherwise available.

    7

     

    

4.2 Notices.
All notices, demands, requests, consents, approvals, and other communications required or permitted hereunder shall be in writing and,
unless otherwise specified herein, shall be (i) personally served, (ii) deposited in the mail, registered or certified, return receipt
requested, postage prepaid, (iii) delivered by reputable air courier service with charges prepaid, or (iv) transmitted by hand delivery,
telegram, or facsimile, addressed as set forth below or to such other address as such party shall have specified most recently by written

such delivery (if delivered other than on a business day during normal business hours where such notice is to be received) or (b) on

4.3 Amendments.
This Note and any provision hereof may only be amended by an instrument in writing signed by the Borrower and the Holder. The term “Note”
and all reference thereto, as used throughout this instrument, shall mean this instrument (and the other Notes issued pursuant to the
Purchase Agreement) as originally executed, or if later amended or supplemented, then as so amended or supplemented.

 

4.4 Assignability.
This Note shall be binding upon the Borrower and its successors and assigns, and shall inure to be the benefit of the Holder and its
successors and assigns. Each transferee of this Note must be an “accredited investor” (as defined in Rule 501(a) of the 1933
Act). Notwithstanding anything in this Note to the contrary, this Note may be pledged as collateral in connection with a bona fide
margin account or other lending arrangement. The Holder and any assignee, by acceptance of this Note, acknowledge and agree that
following conversion of a portion of this Note, the unpaid and unconverted principal amount of this Note represented by this Note may
be less than the amount stated on the face hereof.

    8

     

    

4.5 Governing
Law. This Note shall be governed by and construed in accordance with the laws of the State of Arizona without regard to principles
of conflicts of laws. Any action brought by either party against the other concerning the transactions contemplated by this Note shall
be brought only in the state courts of Arizona or in the federal courts located in the District of Arizona. The parties to this Note
hereby irrevocably waive any objection to jurisdiction and venue of any action instituted hereunder and shall not assert any defense
based on lack of jurisdiction or venue or based upon forum non conveniens. THE BORROWER HEREBY IRREVOCABLY WAIVES ANY RIGHT
IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING
OUT OF THIS NOTE OR ANY TRANSACTION CONTEMPLATED HEREBY. The prevailing party shall be entitled to recover from the other party its
reasonable attorney’s fees and costs. In the event that any provision of this Note or any other agreement delivered in connection herewith
is invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed inoperative to the extent
that it may conflict therewith and shall be deemed modified to conform with such statute or rule of law. Any such provision which may
prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provision of any agreement.
Each party hereby irrevocably waives personal service of process and consents to process being served in any suit, action or proceeding
in connection with this Agreement or any other Transaction Document by mailing a copy thereof via registered or certified mail or overnight
delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit
in any way any right to serve process in any other manner permitted by law.

 

4.6 Certain
Amounts. Whenever pursuant to this Note the Borrower is required to pay an amount in excess of the outstanding principal amount (or
the portion thereof required to be paid at that time) plus accrued and unpaid interest plus Default Interest on such interest, the Borrower
and the Holder agree that the actual damages to the Holder from the receipt of cash payment on this Note may be difficult to determine
and the amount to be so paid by the Borrower represents stipulated damages and not a penalty and is intended to compensate the Holder
in part for loss of the opportunity to convert this Note and to earn a return from the sale of shares of Common Stock acquired upon conversion
of this Note at a price in excess of the price paid for such shares pursuant to this Note. The Borrower and the Holder hereby agree that
such amount of stipulated damages is not plainly disproportionate to the possible loss to the Holder from the receipt of a cash payment
without the opportunity to convert this Note into shares of Common Stock.

 

4.7 Purchase
Agreement. By its acceptance of this Note, each party agrees to be bound by the applicable terms of the Purchase Agreement.

 

4.8 Remedies.
The Borrower acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder, by vitiating the
intent and purpose of the transaction contemplated hereby. Accordingly, the Borrower acknowledges that the remedy at law for a breach
of its obligations under this Note will be inadequate and agrees, in the event of a breach or threatened breach by the Borrower of the
provisions of this Note, that the Holder shall be entitled, in addition to all other available remedies at law or in equity, and in addition
to the penalties assessable herein, to an injunction or injunctions restraining, preventing or curing any breach of this Note and to
enforce specifically the terms and provisions thereof, without the necessity of showing economic loss and without any bond or other security
being required. No provision of this Note shall alter or impair the obligation of the Borrower, which is absolute and unconditional,
to pay the principal of, and interest on, this Note at the time, place, and rate, and in the form, herein prescribed.

 

4.9 Severability.
In the event that any provision of this Note is invalid or unenforceable under any applicable statute or rule of law, then such provision
shall be deemed inoperative to the extent that it may conflict therewith and shall be deemed modified to conform with such statute or
rule of law. Any provision hereof which may prove invalid or unenforceable under any law shall not affect the validity or enforceability
of any other provision hereof.

EXTENSION
AGREEMENT

 

This
EXTENSION AGREEMENT (this “Agreement”) dated as of July 31, 2022 by and between ADAMAS ONE CORP., a Nevada corporation
(“Company”) and Glenn Preslier, an individual (“Investor”). Each of the Company and the Investor
are a “Party” to this Agreement, and one or more of them, as the context shall require, are the “Parties”
hereto.

 

RECITALS:

 

WHEREAS,
the Company has executed and delivered to Investor a certain Convertible Promissory Note Agreement in the principal amount of $250,000.00,
dated March 01, 2022, which as of July 31, 2022, has an aggregate outstanding principal balance of $255,000.00 (the “Note”);

 

WHEREAS,
the Note is due and payable three (3) months after the date of issue;

 

WHEREAS,
the Company has requested that Investor extend the term of the Note to September 30, 2022, and Investor is willing to do so on the terms
and conditions set forth below;

 

NOW,
THEREFORE, for and in consideration of the mutual covenants contained herein and for other valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto agree as follows:

 

1.       Defined
Terms. Capitalized terms used but not defined in this Agreement shall have the meaning given to such capitalized terms in the
Note Purchase Agreements.

 

2.       Extension
of Maturity Date. The maturity date of the Note is hereby extended to 5:00 p.m. New York City, New York Time on October 31, 2022
(the “Maturity Date”).

 

3.       Representations
and Warranties. The Company hereby represents and warrants that (a) ADAMAS ONE CORP. is duly organized and legally existing
under the laws of the State of Nevada; (b)       the execution and delivery of, and performance
under this Agreement are within the Company’s power and authority without the joinder or consent of any other party and have
been duly authorized by all requisite action and are not in contravention of law or the powers of the Company’s respective
organization documents; (c) this Agreement constitutes the legal, valid and binding obligations of the Company enforceable in
accordance with its terms; (d) the execution and delivery of this Agreement by the Company do not contravene, result in a breach of
or constitute a default under any deed of trust, loan agreement, indenture or other contract, agreement or undertaking to which the
Company is a party or by which the Company or any of its properties may be bound (nor would such execution and delivery constitute
such a default with the passage of time or the giving of notice or both) and do not violate or contravene any law, order, decree,
rule or regulation to which the Company is subject; and (e) to the best of the Company’s knowledge there exists no uncured
default under any of the Note Purchase Agreements or Note. The Company agrees to indemnify and hold Investor harmless against any
loss, claim, damage, liability or expense (including without limitation reasonable attorneys’ fees) incurred as a result of any
representation or warranty made by it herein proving to be untrue in any respect.

 

4.       Further
Assurances. The Company, upon request from Investor, agrees to execute such other and further documents as may be reasonably
necessary or appropriate to consummate the transactions contemplated herein.

5.       Default;
Remedies. If the Company shall fail to keep or perform any of the covenants or agreements contained herein (subject to the
applicable notice and cure periods provided in the Note Purchase Agreements) or if any statement, representation or warranty
contained herein is false, misleading or erroneous in any material respect, the Company shall be deemed to be in default under the
Note Purchase Agreements and the Note and Investor shall be entitled at its option to exercise any and all of the rights and
remedies granted pursuant to the Note Purchase Agreements or to which Investor may otherwise be entitled, whether at law or in
equity.

 

6.       Entire
Agreement. This Agreement supersedes and merges all prior and contemporaneous promises, representations and agreements. No modification
of this Agreement or of the Note Purchase Agreements or the Note or any other document related thereto, or any waiver of rights under
any of the foregoing, shall be effective unless made by supplemental agreement, in writing, executed by Investor and the Company. Investor
and the Company further agree that this Agreement may not in any way be explained or supplemented by a prior, existing or future course
of dealings between the parties or by any prior, existing, or future performance between the parties pursuant to this Agreement or otherwise.

 

7.       Notices.
Any notice or communication required or permitted hereunder or under the Note Purchase Agreements shall be given in writing and sent
in the manner required under the Note Purchase Agreements.

 

8.       Costs
and Expenses. Contemporaneously with the execution and delivery hereof, the Company shall pay, or cause to be paid, all costs
and expenses incident to the preparation hereof and the consummation of the transactions specified herein, including without limitation
recording fees and fees and expenses of legal counsel to Investor.

 

9.       Release
of Investor. The Company hereby releases, remises, acquits and forever discharges Investor, together with its manager, members,
participants, employees, agents, representatives, consultants, attorneys, fiduciaries, servants, officers, directors, partners, predecessors,
successors and assigns, (all of the foregoing hereinafter called the “Released Parties”), from any and all actions
and causes of action, judgments, executions, suits, debts, claims, demands, liabilities, obligations, damages and expenses of any and
every character, known or unknown, direct and/or indirect, at law or in equity, of whatsoever kind or nature, whether heretofore or hereafter
accruing, for or because of any matter or things done, omitted or suffered to be done by any of the Released Parties prior to and including
the date hereof, and in any way directly or indirectly arising out of or in any way connected to this Agreement or of the Note Purchase
Agreements including the Note, or any of the transactions associated therewith, including specifically but not limited to claims of usury.

 

10.       Counterparts.
This Agreement may be executed in any number of counterparts with the same effect as if all Parties hereto had signed the same document.
All such counterparts shall be construed together and shall constitute one instrument, but in making proof hereof it shall only be necessary
to produce one such counterpart. Fax or electronic copies of a document shall be deemed an original for all purposes.

 

11.       Severability.
If any covenant, condition, or provision herein contained is held to be invalid by final judgment of any court of competent jurisdiction,
the invalidity of such covenant, condition, or provision shall not in any way affect any other covenant, condition or provision herein
contained.

 

12.       Time
of the Essence. It is expressly agreed by the Parties hereto that time is of the essence with respect to this Agreement.

 

13.       Representation
by Counsel. The Parties acknowledge and confirm that each of their respective attorneys have participated jointly in the
review and revision of this Agreement and that it has not been written solely by counsel for one Party. The Parties hereto therefore
stipulate and agree that the rule of construction to the effect that any ambiguities are to or may be resolved against the drafting
Party shall not be employed in the interpretation of this Agreement to favor either Party against the other.

of law.

 

15.       Successors
and Assigns. The terms and provisions hereof shall be binding upon and inure to the benefit of the Parties hereto and their respective
successors. This Agreement is not assignable by the Company.

Any breach of this Agreement shall be an Event of Default under the Note Purchase Agreements and the Note and the Investor shall have
all rights under the Note Purchase Agreements and the Note in such event.
