CONVERTIBLE PROMISSORY NOTE

$500,000

 

FOR VALUE RECEIVED, BioSolar, Inc.,
a Nevada corporation, (the “Borrower”) with approximately 31,877,834 shares of common stock issued and
outstanding, promises to pay to [__], a [__], or its assignees (the “Lender”) the Principal Sum along
with the Interest and any other fees according to the terms herein (this “Note”). This Note shall become effective
on February 26, 2018 (the “Effective Date”).

 

The Principal Sum is Five Hundred
Thousand Dollars ($500,000) plus accrued and unpaid interest. The total Consideration is Five
Hundred Thousand Dollars ($500,000) payable by wire. The Lender shall pay Fifteen Thousand Dollars ($15,000) of
the Consideration upon execution of this Note (the “Initial Consideration”). The Lender may pay additional Consideration
to the Borrower in such amounts as the Lender may choose in its sole discretion (the “Additional Consideration”). The
Principal Sum due to the Lender, and as referenced hereinafter, shall be the Initial Consideration plus any Additional Consideration
actually paid by the Lender such that the Borrower is only required to repay the amount funded and the Borrower is not required
to repay any unfunded portion of this Note, nor shall any interest or other rights or remedies granted herein extend to any unfunded
portion of this Note. 

 

1.          Maturity
Date. The Maturity Date is twelve (12) months from the Effective Date (the “Maturity Date”)
and is the date upon which the Principal Sum of this Note and unpaid interest and fees (the “Note Amount”) shall be
due and payable. Within thirty (30) days prior to the Maturity Date, the Lender may provide the Borrower with a written notice
to extend the Maturity Date and the Note Amount shall then be payable upon demand, but in no event later than sixty (60) months
from the Effective Date (the ”Extended Maturity Date”). The Lender shall provide the Borrower with ten (10) days written
notice to make a demand for payment (the “Demand Payment Date”), and the Demand Payment Date shall be considered to
be the Extended Maturity Date.

 

2.          Interest. This
Note shall bear interest at the rate of Ten Percent (10%) per year.

 

3.         Conversion.
The Lender has the right, at any time after the Effective Date, at its election, to convert all or part of the Note Amount into
shares of fully paid and non-assessable shares of common stock of the Borrower (the “Common Stock”). The conversion
price (the “Conversion Price”) shall be the lesser of (a) $0.03 per share of Common Stock or (b) Fifty Percent
(50%) of the lowest trade price of Common Stock recorded on any trade day after the Effective Date, or (c) the lowest effective
price per share granted to any person or entity, including the Lender but excluding officers and directors of the Borrower, after
the Effective Date to acquire Common Stock, or adjust, whether by operation of purchase price adjustment, settlement agreements,
exchange agreements, reset provision, floating conversion or otherwise, any outstanding warrant, option or other right to acquire
Common Stock or outstanding Common Stock equivalents (the “Conversion Price”). The conversion formula shall be as follows:
Number of shares receivable upon conversion equals the dollar conversion amount divided by the Conversion Price. A conversion notice
(the “Conversion Notice”) may be delivered to Borrower by method of Lender’s choice (including but not limited
to email, facsimile, mail, overnight courier, or personal delivery), and all conversions shall be cashless and not require further
payment from the Lender. If no objection is delivered from the Borrower to the Lender, with respect to any variable or calculation
reflected in the Conversion Notice within 24 hours of delivery of the Conversion Notice, the Borrower shall have been thereafter
deemed to have irrevocably confirmed and irrevocably ratified such notice of conversion and waived any objection thereto. The Borrower
shall deliver the shares of Common Stock from any conversion to the Lender (in any name directed by the Lender) within three (3)
business days of Conversion Notice delivery. If the Borrower is participating in the Depository Trust Company (“DTC”)
Fast Automated Securities Transfer (“FAST”) program, then upon request of the Lender and provided that the shares to
be issued are eligible for transfer under Rule 144 of the Securities Act of 1933, as amended (the “Securities Act”),
or are effectively registered under the Securities Act, the Borrower shall cause its transfer agent to electronically issue the
Common Stock issuable upon conversion to the Lender through the DTC Direct Registration System (“DRS”). If the Borrower
is not participating in the DTC FAST program, then after receiving the Initial Consideration, the Borrower agrees to begin a good
faith effort to apply and cause the approval for participation in the DTC FAST program. The Conversion Price shall be subject to
equitable adjustments for stock splits, stock dividends or rights offerings by the Borrower relating to the Borrower’s securities
or the securities of any subsidiary of the Borrower, combinations, recapitalization, reclassifications, extraordinary distributions
and similar events.

 

    	 	1	 

     

    

 

4.          Conversion
Delays. If Borrower fails to deliver shares in accordance with the timeframe stated in Section 3, the Lender, at any
time prior to selling all of those shares, may rescind any portion, in whole or in part, of that particular conversion attributable
to the unsold shares and have the rescinded conversion amount returned to the Principal Sum with the rescinded conversion shares
returned to the Borrower (under the Lender’s and the Borrower’s expectations that any returned conversion amounts
shall tack back to the original date of this Note). In addition, for each conversion, in the event that shares are not delivered
by the fourth business day (inclusive of the day of conversion), a penalty of $1,500 per day shall be assessed for each day after
the third business day (inclusive of the day of the conversion) until share delivery is made; and such penalty shall be added
to the Principal Sum of this Note (under the Lender’s and the Borrower’s expectations that any penalty amounts shall
tack back to the original date of this Note consistent with applicable securities laws).

 

5.          Limitation
of Conversions. In no event shall the Lender 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 Lender and its affiliates
(other than shares of Common Stock which may be deemed beneficially owned through the ownership of the unconverted portion of this
Note 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 Lender and its affiliates of more than 4.99% of the outstanding shares of Common Stock. For purposes of the proviso of 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 Lender upon, at the election
of the Lender, 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 Lender, as may be specified in such notice of waiver).

 

    	 	2	 

     

    

 

6.          Payment.
The Borrower may not prepay this Note prior to the Maturity Date or the Extended Maturity Date, if extended by the Lender. Within
six (6) days prior to the Maturity Date or Extended Maturity Date, the Borrower shall provide the Lender with a written notice
to pay the Note Amount on the Maturity Date or Extended Maturity Date. Within three (3) days of receiving written notice, the Lender
shall elect to either (a) accept payment of the Note Amount or (b) convert any part of the Note Amount into shares of Common Stock.
If the Lender elects to convert part of the Note Amount into shares of Common Stock, then the Borrower shall pay the remaining
balance of the Note Amount by the Maturity Date or Extended Maturity Date.

 

7.          Piggyback
Registration Rights. The Borrower shall include on the next registration statement the Borrower files with the SEC (or on the
subsequent registration statement if such registration statement is withdrawn) all shares of Common Stock issuable upon conversion
of this Note unless such shares of Common Stock are eligible for resale under Rule 144, excluding S-8 registration statements for
employee stock grant and option plans. Failure to do so shall result in liquidated damages of Twenty Five Percent (25%)
of the outstanding principal balance of this Note being immediately due and payable to the Lender at its election in the form of
cash payment or addition to the balance of this Note.

 

8.          Lender’s
Representations. The Lender hereby represents and warrants to the Borrower that (i) it is an “accredited investor”
as such term is defined in Rule 501(a) of Regulation D promulgated under the Securities Act, (ii) it understands that this Note
and the shares of Common Stock underlying this Note (collectively, the “Securities”) have not been registered under
the Securities Act by reason of a claimed exemption under the provisions of the Securities Act that depends, in part, upon the
Lender’s investment intention; in this connection, the Lender hereby represents that it is purchasing the Securities for
the Lender’s own account for investment and not with a view toward the distribution to others; provided, that Lender may
syndicate participations in the Securities among a limited number of participants who all meet the suitability standards of an
“accredited investor” as defined in Rule 501(a) of Regulation D of the Securities Act and will share among themselves
and the Lender an economic interest in the Securities on a pari passu, pass through basis with investment intent, such that the
availability of the private placement exemption for the issuance of the Note under Rule 506 of Regulation D of the Securities Act
is preserved, (iii) the Lender, if an entity, further represents that it was not formed for the purpose of purchasing the Securities,
(iv) the Lender acknowledges that the issuance of this Note has not been reviewed by the United States Securities and Exchange
Commission (the “SEC”) nor any state regulatory authority since the issuance of this Note is intended to be exempt
from the registration requirements of Section 4(2) of the Securities Act and Rule 506 of Regulation D, and (v) the Lender acknowledges
receipt and careful review of this Note, the Borrower’s filings with the SEC (including without limitation, any risk factors
included in the Borrower’s most recent Annual Report on Form 10-K), and any documents which may have been made available
upon request as reflected therein, and hereby represents that it has been furnished by the Borrower with all information regarding
the Borrower, the terms and conditions of the purchase and any additional information that the Lender has requested or desired
to know, and has been afforded the opportunity to ask questions of and receive answers from duly authorized officers or other representatives
of the Borrower concerning the Borrower and the terms and conditions of the purchase.

 

    	 	3	 

     

    

 

9.          Borrower’s
Representations. The Borrower hereby represents and warrants to the Lender that (i) the Borrower is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its organization with full power and authority to own, lease,
license and use its properties and assets and to carry out the business in which it proposes to engage, and (ii) the Borrower has
the requisite corporate power and authority to execute, deliver and perform its obligations under this Note and to issue and sell
this Note, and (iii) all necessary proceedings of the Borrower have been duly taken to authorize the execution, delivery, and performance
of this Note, and when this Note is executed and delivered by the Borrower, it will constitute the legal, valid and binding obligation
of the Borrower enforceable against the Borrower in accordance with their terms, except as such enforceability may be limited by
general principles of equity or to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar
laws relating to, or affecting generally, the enforcement of applicable creditors' rights and remedies.

 

10.        Default.
The following are events of default under this Note: (i) the Borrower shall fail to pay any principal under this Note when due
and payable (or payable by conversion) thereunder; or (ii) the Borrower shall fail to pay any interest or any other amount under
this Note when due and payable (or payable by conversion) thereunder; or (iii) a receiver, trustee or other similar official shall
be appointed over the 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; or (iv) the 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; or
(v) the Borrower shall make a general assignment for the benefit of creditors; or (vi) the Borrower shall file a petition for relief
under any bankruptcy, insolvency or similar law (domestic or foreign); or (vii) an involuntary proceeding shall be commenced or
filed against the Borrower; or (viii) the Borrower shall lose its status as “DTC Eligible” or the Borrower’s
shareholders shall lose the ability to deposit (either electronically or by physical certificates, or otherwise) shares into the
DTC System; or (ix) the Borrower shall become delinquent in its filing requirements as a fully-reporting issuer registered with
the SEC; or (x) the Borrower shall commit a material breach of any of its covenants, representations or warranties in this Note.

 

11.       Remedies.
In the event of any default, the funded portion of the Note Amount shall become immediately due and payable at the Mandatory Default
Amount. The Mandatory Default Amount shall be 150% of the funded portion of the Note Amount. Commencing five (5) days after
the occurrence of any event of default that results in the eventual acceleration of this Note, the interest rate on the Mandatory
Default Amount shall accrue at a default interest rate equal to the lesser of ten percent (10%) per annum or the maximum rate permitted
under applicable law. In connection with such acceleration described herein, the Lender need not provide, and the Borrower hereby
waives, any presentment, demand, protest or other notice of any kind, and the 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. While the Mandatory Default Amount is outstanding and default interest is accruing, the Lender shall have all rights as a
holder of this Note until such time as the Lender receives full payment pursuant to this paragraph, or has converted all the remaining
Mandatory Default Amount and any other outstanding fees and interest into Common Stock under the terms of this Note. In the event
of any default and at the request of the Lender, the Borrower shall file a registration statement with the SEC to register all
shares of Common Stock issuable upon conversion of this Note that are otherwise not eligible to have their restrictive transfer
legend removed under Rule 144 of the Securities Act. 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 the Borrower’s failure to timely deliver certificates representing shares of Common Stock upon conversion of this
Note as required pursuant to the terms hereof. The Borrower may only pay the full balance of the Mandatory Default Amount, and
may not make partial payments unless agreed upon by the Lender. If the Borrower desires to pay the Mandatory Default Amount, then
the Borrower shall provide the Lender with six (6) days prior written notice of payment. Within three (3) days of receiving written
notice, the Lender shall elect to either (a) accept payment, or (b) convert any part of the payment into shares of Common Stock.
If the Lender elects to convert part of the payment into shares of Common Stock, then the Borrower shall pay the remaining balance
of the Mandatory Default Amount.

12.        No
Shorting. Lender agrees that so long as this Note from Borrower to Lender remains outstanding, the Lender shall not enter into
or effect “short sales” of the Common Stock or hedging transaction which establishes a short position with respect
to the Common Stock of the Borrower. The Borrower acknowledges and agrees that upon delivery of a Conversion Notice by the Lender,
the Lender immediately owns the shares of Common Stock described in the Conversion Notice and any sale of those shares issuable
under such Conversion Notice would not be considered short sales.

 

13.       Assignability.
The Borrower may not assign this Note. This Note shall be binding upon the Borrower and its successors and shall inure to the benefit
of the Lender and its successors and assigns and may be assigned by the Lender, in whole or in part, to anyone of its choosing
without Borrower’s approval subject to applicable securities laws. Lender covenants not to engage in any unregistered public
distribution of the Note when making any assignments.

 

14.        Governing
Law. This Note shall be governed by, and construed and enforced in accordance with, the laws of the State of Nevada,
without regard to the conflict of laws principles thereof. Any action brought by either party against the other concerning the
transactions contemplated by this Agreement shall be brought only in the state courts of Nevada or in the federal courts
located in Clark County, in the State of Nevada. Both parties and the individuals signing this Agreement agree to
submit to the jurisdiction of such courts.

 

15.        Delivery
of Process by the Lender to the Borrower. In the event of any action or proceeding by the Lender against the Borrower, and
only by the Lender against the Borrower, service of copies of summons and/or complaint and/or any other process which may be served
in any such action or proceeding may be made by the Lender via U.S. Mail, overnight delivery service such as FedEx or UPS, email,
fax, or process server, or by mailing or otherwise delivering a copy of such process to the Borrower at its last known attorney
as set forth in its most recent SEC filing.

 

16.        Attorney
Fees. In the event any attorney is employed by either party to this Note with regard to any legal or equitable action, arbitration
or other proceeding brought by such party for the enforcement of this Note or because of an alleged dispute, breach, default or
misrepresentation in connection with any of the provisions of this Note, the prevailing party in such proceeding shall be entitled
to recover from the other party reasonable attorneys' fees and other costs and expenses incurred, including but not limited to
post judgment costs, in addition to any other relief to which the prevailing party may be entitled.

17.        Transfer
Agent Instructions. In the event that an opinion of counsel, such as but not limited to a Rule 144 opinion, is needed for any
matter related to this Note or the Common Stock the Lender has the right to have any such opinion provided by its counsel. If the
Lender chooses to have its counsel provide such opinion, then the Lender shall provide the Borrower with written notice. Within
three (3) business days of receiving written notice, the Borrower shall instruct its transfer agent to rely upon opinions from
the Lender’s counsel. A penalty of $1,500 per day shall be assessed for each day after the third business day (inclusive
of the day of request) until the reliance instruction is delivered to the transfer agent. If the Lender requests that the Borrower’s
counsel issue an opinion, then the Borrower shall cause the issuance of the requested opinion within three (3) business days. A
penalty of $1,500 per day shall be assessed for each day after the third business day (inclusive of the day of request) until the
requested opinion is delivered. The Lender and the Borrower agree that all penalty amounts shall be added to the Principal Sum
of this Note and shall tack back to the Effective Date of this Note, with respect to the holding period under Rule 144, so long
as such treatment is not inconsistent with Rule 144’s applicable tacking provisions. The Borrower warrants that it will not
direct its transfer agent not to transfer or delay, impair, and/or hinder its transfer agent in transferring (or issuing)(electronically
or in certificated form) any certificate for the Securities to be issued to the Lender and it will not fail to remove (or direct
its transfer agent not to remove or impair, delay, and/or hinder its transfer agent from removing) any restrictive legend (or to
withdraw any stop transfer instructions in respect thereof) on any certificate for the Securities when required by this Note. The
Borrower acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Lender by vitiating the
intent and purpose of the transactions contemplated hereby. Accordingly, the Borrower acknowledges that the remedy at law for a
breach of its obligations under this Note may be inadequate and agrees, in the event of a breach or threatened breach by the Borrower
of these provisions, that the Lender shall be entitled, in addition to all other available remedies, to an injunction restraining
any breach and requiring immediate transfer, without the necessity of showing economic loss and without any bond or other security
being required.

 

18.        Reservation
of Shares.  At all times during which this Note is convertible, the Borrower shall 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.

 

19.        Disclosure
of Material Non-Public Information. The Borrower agrees not to disclose any material non-public information to the Lender after
the Effective Date. If the Borrower inadvertently discloses any material non-public information to the Lender, then the
Borrower shall promptly publicly disclose that information by filing a Form 8-K with the SEC and by any other means necessary
to make that information known to the public.

 

20.        Public
Disclosure. The Lender and the Borrower agree not to issue any public statement with respect to the Lender’s investment
or proposed investment in the Borrower or the terms of any agreement or covenant without the other party’s prior written
consent, except such disclosures as may be required under applicable law or under any applicable order, rule or regulation. The
Borrower agrees to reference Lender only as “an accredited investor” and attach only a form copy of this Note in any
of the Borrower’s filings with the Securities and Exchange Commission or any other public filings, except such full disclosures
as may be required under applicable law or under any applicable order, rule or regulation.

22.        Lender’s
Right to Elect a Fixed Conversion Price. The Borrower agrees that the Lender shall have the right, at its sole discretion,
to elect a fixed conversion price for this Note (the “Fixed Conversion Price”) instead of the formula described in
Section 3 above. However, the Fixed Conversion Price shall not be lower than the Conversion Price as determined by Section 3 above.

 

22.        Lender’s
Right to Convert to Convertible Preferred Stock. The Borrower agrees that the Lender shall have the right, at its sole discretion,
