(iii)           
In addition to the restriction set forth in clause (ii) above, at any time on or prior to the later of (x) the date no Notes
remain outstanding and (y) the six month anniversary of the Closing Date, other than with respect to Excluded Securities, neither
the Company nor any of its Subsidiaries shall, directly or indirectly, effect any Subsequent Placement unless the Company shall
have first complied with this Section 6.2(iii). The Company acknowledges and agrees that the right set forth in this
Section 6.2(iii) is a right granted by the Company, separately, to the Investor and each Other Investor.

 

    10

     

    

 

(1)   The
Company shall deliver to the Investor an irrevocable written notice (the "Offer Notice") of any
proposed or intended issuance or sale (the "Offer") of the securities being offered (the
 "Offered Securities") in a Subsequent Placement, which Offer Notice shall
(v) include any offering documents and definitive documentation in connection with such Offer, (w) identify and describe the
Offered Securities, (x) describe the price and other terms upon which they are to be issued and sold, and the number or
amount of the Offered Securities to be issued and sold, and (y)  offer to issue and sell to or exchange with the
Investors at least twenty percent (20%) of the Offered Securities, allocated among the Investors based on the
Investor’s and each Other Investor's pro rata portion of the aggregate principal amount of Notes issued pursuant to
this Agreement and the Other Exchange Agreements (each, a "Basic Amount") and (z) if the Investor
elects to purchase its Basic Amount, any additional portion of the Offered Securities attributable to the Basic Amounts of
other Investors as the Investor shall indicate it will purchase or acquire should the other Investors subscribe for less than
their Basic Amounts (the “Undersubscription Amount”), which process shall be repeated until all
Investors shall have an opportunity to subscribe for any remaining Undersubscription Amount.

 

(2)  
To accept an Offer, in whole or in part, the Investor must deliver a written notice to the Company prior
to 6:00 P.M., New York City time, on the first (1st) Trading Day immediately following the day in which the Investor received
such Offer Notice (the "Offer Period"), setting forth the portion of the Investor's Basic Amount that the
Investor, or an affiliate of the Investor that it designates, elects to purchase and, if the Investor or its designee shall elect
to purchase all of its Basic Amount, the portion of any Undersubscription Amount, if any, that the Investor or its designee elects
to purchase (in either case, the "Notice of Acceptance"). Notwithstanding anything to the contrary contained
herein, if the Company desires to modify or amend the terms and conditions of the Offer prior to the expiration of the Offer Period,
the Company may deliver to the Investor a new Offer Notice and the Offer Period shall expire at 6:00
P.M., New York City time, on the first (1st) Trading Day immediately following the day in which the Investor received such
new Offer Notice. If the Basic Amounts subscribed for by the Investors are less than the total of all of the Basic Amounts and
the Investor has subscribed for its entire Basic Amount and an Undersubscription Amount in its Notice of Acceptance, then the Investor
shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed
for; provided, however, if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic
Amounts and the Basic Amounts subscribed for (the “Available Undersubscription Amount”), the Investor
shall only be entitled to purchase only that portion of the Available Undersubscription Amount as the Basic Amount of the Investor
bears to the total Basic Amounts of all Investors that have subscribed for Undersubscription Amounts, subject to rounding by the
Company to the extent it deems reasonably necessary.

 

(3)   The
Company shall have ten (10) Trading Days from the expiration of the Offer Period above (the “Offer Expiration
Date”) to offer, issue or sell all or any part of such Offered Securities as to which a Notice of Acceptance has
not been given by the Investors (the "Refused Securities") pursuant to a definitive agreement (the
 "Subsequent Placement Agreement"), but only upon terms and conditions (including, without limitation, unit
prices and interest rates) that are not more favorable to the acquiring Person or Persons or less favorable to the Company
than those set forth in the Offer Notice. Upon the closing of the issuance or sale of all or less than all of the Refused
Securities, the Investor or its designees shall acquire from the Company, and the Company shall issue to the Investor, the
number or amount of Offered Securities specified in the Notices of Acceptance if the Investor has so elected, upon the terms
and conditions specified in the Offer.

 

    11

     

    

 

(4)   Any Offered Securities not acquired by the Investor, the Other Investors or other Persons in accordance with Section
6.2(iii)(3) above may not be issued or sold until they are again offered to the Investor under the procedures specified in
this Section 6.2(iii).

 

(5)   The Company and the Investor agree that if the Investor elects to participate in the Offer, (x) neither the Subsequent Placement
Agreement with respect to such Offer nor any other transaction documents related thereto shall include any term or provisions whereby
the Investor shall be required to agree to any restrictions in trading as to any securities of the Company owned by the Investor
prior to such Subsequent Placement or be required to consent to any amendment to or termination of, or grant any waiver, release
or the like under or in connection with, any agreement previously entered into with the Company or any instrument received from
the Company and (y) the Investor or its designees shall be entitled to the same registration rights provided to other investors
in the Subsequent Placement.

 

(6)   Notwithstanding anything to the contrary in this Section 6.2(iii) and unless otherwise agreed to by the Investor,
the Company shall either confirm in writing to the Investor that the transaction with respect to the Subsequent Placement has been
abandoned or shall publicly disclose its intention to issue the Offered Securities, in either case in such a manner such that the
Investor will not be in possession of any material, non-public information, by the Offer Expiration Date. If by the Offer Expiration
Date no public disclosure regarding a transaction with respect to the Offered Securities has been made, and no notice regarding
the abandonment of such transaction has been received by the Investor, such transaction shall be deemed to have been abandoned
and the Investor shall not be deemed to be in possession of any material, nonpublic information with respect to the Company. Should
the Company decide to pursue such transaction with respect to the Offered Securities, the Company shall provide the Investor and
each Other Investor with another Offer Notice and the Investor and each Other Investor will again have the right of participation
set forth in this Section 6.2(iii).

 

    12

     

    

 

(7)   The
restrictions contained in this Section 6.2(iii) shall not apply in connection with the following “Excluded
Securities”: (A) issuances under any employee benefit plan or made pursuant to Nasdaq Listing Rule 5635(c)(4), and
the exercise or conversion, as applicable, of any Common Stock Equivalents issued under any employee benefit plan or made

shares issuable thereunder and none of the terms or conditions of any such Common Stock Equivalents are otherwise materially
changed in any manner that adversely affects any of the Investors; (B) shares of Common Stock and/or Common Stock
Equivalents, as applicable, issuable upon conversion or exercise, as applicable, of any Common Stock Equivalents which are

date hereof (provided that such Common Stock Equivalents are not amended, modified or changed on or after the date hereof);
(C) any issuances of Common Stock pursuant to an offering by the Company of newly issued shares of Common Stock, which is
incrementally sold into the Principal Market through a broker-dealer at the market price on the Principal Market in effect at
the time of each such sale; (D) any issuances of Common Stock Equivalents upon conversion or exercise, as applicable, of any
other Excluded Security hereunder pursuant to the terms of such other Excluded Security in effect on the date hereof
(provided, that such other Excluded Security is not amended, modified or changed on or after the date hereof); (E) any
issuances of Common Stock and/or Common Stock Equivalents in exchange for any Common Stock Equivalents outstanding on the
date hereof (provided, that any such exchange shall not include any payment, directly or indirectly, to the Company (or any
of its subsidiaries or affiliates) of any consideration (cash or otherwise) by the holder of such Common Stock Equivalents
(or any of its affiliates)); (F) the Stock Issuance; (G) the Exchange and any Exchange (as defined in any Other Exchange
Agreement); (H) any shares of Common Stock issued or issuable in connection with any bona fide strategic or commercial

solely consists of either (I) the actual participants in such strategic or commercial alliance, strategic or commercial
licensing arrangement or strategic or commercial partnership, (II) the actual owners of such assets or securities acquired in
such acquisition or merger or (III) the stockholders, partners, employees, consultants, officers, directors or members of the
foregoing Persons, in each case, which is, itself or through its subsidiaries, an operating company or an owner of an asset,
in a business synergistic with the business of the Company and shall provide to the Company additional benefits in addition
to the investment of funds; (I) shares of Common Stock issued to satisfy accounts payables owed by the Company and/or any of
its Subsidiaries to a Person (the “Payee”); provided, that such shares of Common Stock are to be issued
solely to such Payee (or its broker-dealer) in satisfaction of such applicable accounts payable without such Payee’s
intent to transfer such Common Stock to any other Person in exchange for cash or other similar compensation (other than
ordinary sales through a broker-dealer on the Principal Market); and (J) an issuance to a research or non-profit foundation
or organization, in each case qualified under Section 501(c) of the Internal Revenue Code of 1986, as amended, in connection
with an equity financing of the Company with gross proceeds to the Company not to exceed Five Million Dollars
($5,000,000).

 

6.3              Disclosure.
The Company shall file a current report on Form 8-K on or before 8:30 a.m., New York City time, on April 22, 2020, describing
the terms of the transactions contemplated by this Agreement, all in the form required by the Exchange Act and attaching the
form of this Agreement and the Form of Note (and all schedules and exhibits thereto not otherwise attached), as exhibits to
such filing (including all attachments, the “8 K Filing”). As of immediately following the filing of the
8-K Filing with the SEC, the Investor shall not be in possession of any material, nonpublic information received from the
Company, any of its direct or indirect subsidiaries (“Subsidiaries”) or any of their respective officers,
directors, employees, affiliates or agents, that is not disclosed in the 8-K Filing or in prior filings with the SEC. In
addition, effective upon the filing of the 8-K Filing, the Company acknowledges and agrees that any and all confidentiality
or similar obligations under any agreement, whether written or oral, between the Company, any of its Subsidiaries or any of
their respective officers, directors, employees, affiliates or agents, on the one hand, and the Investor or any of its
affiliates, on the other hand, shall terminate and be of no further force or effect. The Company shall not, and shall cause
its Subsidiaries and its and each of their respective officers, directors, employees, affiliates and agents, not to, provide
the Investor with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the
date hereof without the express prior written consent of the Investor. To the extent that the Company, its Subsidiaries or
any of its or their respective officers, directors, employees, affiliates or agents delivers any material, non-public
information regarding the Company or any of its Subsidiaries to the Investor without the Investor’s express prior
written consent, the Company hereby covenants and agrees that the Investor shall not have any duty of confidentiality to the
Company, any of its Subsidiaries or any of their respective officers, directors, employees, affiliates or agents with respect
to, or a duty to the Company, any of its Subsidiaries or any of their respective officers, directors, employees, affiliates
or agents not to trade on the basis of, such material, non-public information. The Company understands and confirms that the
Investor will rely on the foregoing in effecting transactions in securities of the Company.

 

    13

     

    

 

6.4             
Most Favored Nations. The Company hereby represents and warrants as of the date hereof and covenants and agrees from
and after the date hereof that none of the terms agreed to with any Person relating to the amendment and/or exchange of the Warrants
(or any amendment thereof) (other than the reimbursement of legal fees), is or will be more favorable to such Person than those
of the Investor and this Agreement.

 

6.5             
Fees and Expenses. Each party shall pay the fees and expenses of its advisers, counsel, accountants and other experts,
if any, and all other expenses incurred by such party incident to the negotiation, preparation, execution, delivery and performance
of this Agreement.

 

6.6             
Section 3(a)(9) Exchange. The Company acknowledges and agrees that the
offer and sale of the Exchange Securities, in conformity with the terms of this Agreement, are exempt from the registration requirements
of Section 5 of the Securities Act by virtue of Section 3(a)(9) thereof and that the
holding period of the Exchange Securities being exchanged therefor may be tacked on to the holding period of such Existing Warrants.  The
Company agrees not to take any position contrary to this Section 6.6. In consideration for the Company agreeing to issue the Shares
being exchanged for Existing Warrants to the Investor via the DWAC system without any restrictive legend, the Investor acknowledges
and agrees that it will not sell any of the Shares issued in exchange for Existing Warrants at any time that the Investor is notified
by the Company in writing that the Company is not in compliance with its filing obligations under the Exchange Act at a time when
such compliance is required for the Investor to sell the Shares pursuant to Rule 144. In addition, upon any such event, if requested
by the Company, the Investor covenants and agrees to promptly return any Shares held by the Investor at such time pursuant to written
directions given by the Company so that the Company (or its transfer agent) may add restrictive legends to such Shares consistent
with the legend set forth in Section 2(g) of the Securities Purchase Agreement.

 

    14

     

    

 

6.7             
Public Information Failure. At any time from and after the Effective Time and ending at such time that all of the
Exchange Securities may be sold without the requirement for the Company to be in compliance with Rule 144(c)(1) and otherwise without
restriction or limitation pursuant to Rule 144, if the Company (i) shall fail for any reason to satisfy the current public information
requirement under Rule 144(c) or (ii) has ever been an issuer described in Rule 144(i)(1)(i) or becomes an issuer in the future,
and the Company shall fail to satisfy any condition set forth in Rule 144(i)(2) (a “Public Information Failure”)
then, in addition to the Investor’s other available remedies, the Company shall pay to the Investor, in cash, as partial
liquidated damages and not as a penalty, by reason of any such delay in or reduction of its ability to sell the Shares, an amount
in cash equal to two percent (2.0%) of the product of (x) the largest number of Shares held by the Investor during any Public Information
Failure and (y) the greatest Closing Sale Price (as defined in the Warrants) of the Common stock during any Public Information
Failure, and on every thirtieth (30th) day (pro-rated for periods totaling less than thirty days) thereafter until the earlier
of (a) the date such Public Information Failure is cured and (b) such time that such public information is no longer required for
the Investor to transfer the Shares pursuant to Rule 144. The payments to which the Investor shall be entitled pursuant to
this Section 6.7 are referred to herein as “Public Information Failure Payments.” Public Information
Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure
Payments are incurred and (ii) the third (3rd) business day after the event or failure giving rise to the Public Information Failure
Payments is cured. In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public Information
Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full. Nothing herein
shall limit the Investor’s right to pursue actual damages for the Public Information Failure, and the Investor shall have
the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance
and/or injunctive relief.

application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the
exclusive jurisdiction of the state or federal courts sitting in The City of New York, Borough of Manhattan, for the

No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective
permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

Ocugen,
Inc.

 

SENIOR
NOTE

 

	Issuance Date:  April 22, 2020	Original Principal Amount: U.S. $[•]

 

FOR VALUE RECEIVED,
Ocugen, Inc., a Delaware corporation (the "Company"), hereby promises to pay to [HOLDER] or registered assigns
(the "Holder") in cash the amount set out above as the Original Principal Amount (as reduced pursuant to the terms
hereof pursuant to redemption or otherwise, the "Principal") when due, whether upon the Maturity Date (as defined
below), prepayment, acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and, if an Event of
Default has occurred and is continuing, to pay interest ("Interest") on any outstanding Principal at the applicable
Default Rate (as defined below) when the same becomes due and payable, whether upon the Maturity Date, prepayment, acceleration,
redemption or otherwise (in each case in accordance with the terms hereof). This Senior Note (including all Senior Notes issued
in exchange, transfer or replacement hereof, this "Note") is one of an issue of Senior Notes issued pursuant to
the Exchange Agreement (as defined below) on the Issuance Date (collectively, the "Notes" and such other Senior
Notes issued on the same date pursuant to the Other Exchange Agreements (as defined below), the "Other Notes").
Certain capitalized terms used herein are defined in Section 27.

 

(1)  
PAYMENTS OF PRINCIPAL. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing 100%
of the Outstanding Amount. Other than as specifically permitted by this Note, the Company may not prepay any portion of the outstanding
Principal, accrued and unpaid Interest on Principal, if any.

 

(2)  
PREPAYMENTS. 

 

(a)   Optional
Prepayment. The Company may prepay (each, an "Optional Prepayment") the Note in whole or in part at any
time or from time to time without penalty or premium by paying the Outstanding Amount being prepaid at a price equal to 100%
of the Outstanding Amount being prepaid (the "Optional Prepayment Price"). The Company may exercise its
right to require prepayment under this Section 2(a) by delivering a written notice thereof by electronic mail and overnight
courier to the Holder and all, but not less than all, of the holders of the Other Notes (an "Optional Prepayment
Notice" and the date all of the holders of the Notes received such notice is referred to as the "Optional
Prepayment Notice Date"). Each Optional Prepayment Notice shall be irrevocable. Each Optional Prepayment Notice
shall (i) state the date on which the applicable Optional Prepayment shall occur (the "Optional Prepayment
Date"), which date shall not be less than two (2) Business Days nor more than fifteen (15) Business Days following
such Optional Prepayment Notice Date and (ii) state the aggregate Outstanding Amount of the Notes which the Company has
elected to be subject to Optional Prepayment from the Holder and all of the other holders of the Other Notes pursuant to this
Section 2(a) (and analogous provisions under the Other Notes) on the Optional Prepayment Date.

 

    

     

    

 

(b)  
Mandatory Prepayments. At any time and from time to time after the Issuance Date, to the extent the Company or any
of its Subsidiaries consummates a Financing Transaction (the date of the consummation of such Financing Transaction, a "Mandatory
Prepayment Event Date"), the Company shall be required to use the applicable Mandatory Prepayment Percentage of the applicable
Financing Net Proceeds to redeem the Outstanding Amount then remaining under this Note and the Other Notes on the applicable Mandatory
Prepayment Date (as defined below) (a "Mandatory Prepayment" and together with an "Optional Prepayment",
a "Prepayment"). For the avoidance of doubt, if the Mandatory Prepayment Percentage of any applicable Financing
Net Proceeds exceed the Outstanding Amount of this Note, the Company shall not be required to pay to the Holder more than the Outstanding
Amount of this Note. The Company shall effect multiple Mandatory Prepayments, as necessary, to redeem in full all Outstanding Amounts
under this Note and the Other Notes. The portion of this Note subject to prepayment pursuant to this Section 2(b) shall be prepaid
by the Company in cash at a price equal to 100% of the Outstanding Amount being prepaid (a "Mandatory Prepayment Price"
and together with an Optional Prepayment Price, a "Prepayment Price"). The Company shall effect a Mandatory Prepayment
under this Section 2(b) by delivering a written notice thereof within no later than one (1) Business Day prior to the applicable
Mandatory Prepayment Event Date by electronic mail and overnight courier to the Holder and all, but not less than all, of the holders
of the Other Notes (a "Mandatory Prepayment Notice"). Each Mandatory Prepayment Notice shall be irrevocable. Each
Mandatory Prepayment Notice shall (x) state the date on which the applicable Mandatory Prepayment shall occur (a "Mandatory
Prepayment Date" and together with an Optional Prepayment Date, a "Prepayment Date") which date shall
not be more than five (5) Business Days following the applicable Mandatory Prepayment Event Date (except with respect to any “at
the market” equity offering or committed equity arrangement, with respect to which the “Mandatory Prepayment Date”
shall be the third Business Day after each full calendar month during the term of any such financing), (y) state the amount of
the applicable Financing Net Proceeds raised by the Company or its Subsidiary, as applicable, in the applicable Financing Transaction
and (z) state the aggregate Outstanding Amount of the Notes which is being prepaid in such Mandatory Prepayment from the Holder
pursuant to this Section 2(b) and all of the holders of the Other Notes pursuant to analogous provisions under the Other Notes
on the applicable Mandatory Prepayment Date.

 

(c)  
Pro Rata Prepayment Requirement. If the Company elects to cause an Optional Prepayment of this Note pursuant to Section
2(a) or is required to cause a Mandatory Prepayment pursuant to Section 2(b), then it must simultaneously take the same action
with respect to all of the Other Notes, and if any Prepayment of this Note pursuant to this Section 2 is for a portion of this
Note, then, it must simultaneously take the same action in the same proportion with respect to all of the Other Notes on a pro
rata basis based on the Principal amount of Notes then outstanding. Prepayments made pursuant to this Section 2 shall be made in
accordance with Section 8.

(3)   REGISTRATION;
BOOK-ENTRY. The Company shall maintain a register (the "Register") for the recordation of the names and
addresses of the holders of each Note and the Principal amount of the Notes held by such holders (the "Registered
Notes"). The entries in the Register shall be conclusive and binding for all purposes absent manifest error. The
Company and the holders of the Notes shall treat each Person whose name is recorded in the Register as the owner of a Note
for all purposes, including, without limitation, the right to receive payments of Principal and Interest, if any, hereunder,
notwithstanding notice to the contrary. A Registered Note may be assigned or sold in whole or in part only by registration of
such assignment or sale on the Register. Upon its receipt of a request to assign or sell all or part of any Registered Note
by the Holder, the Company shall record the information contained therein in the Register and issue one or more new
Registered Notes in the same aggregate Principal amount as the Principal amount of the surrendered Registered Note to the
designated assignee or transferee pursuant to Section 13. Notwithstanding anything to the contrary in this Section 3, the
Holder may assign any Note or any portion thereof to an Affiliate of such Holder or a Related Fund of such Holder without
delivering a request to assign or sell such Note to the Company and the recordation of such assignment or sale in the
Register (a "Related Party Assignment"); provided, that (x) the Company may continue to deal solely
with such assigning or selling Holder unless and until such Holder has delivered a request to assign or sell such Note or
portion thereof to the Company for recordation in the Register; (y) the failure of such assigning or selling Holder to
deliver a request to assign or sell such Note or portion thereof to the Company shall not affect the legality, validity, or
binding effect of such assignment or sale and (z) such assigning or selling Holder shall, acting solely for this purpose as a
non-fiduciary agent of the Company, maintain a register (the "Related Party Register") comparable to the
Register on behalf of the Company, and any such assignment or sale shall be effective upon recordation of such assignment or
sale in the Related Party Register.

 

(4)  
INTEREST; DEFAULT RATE. No Interest shall accrue hereunder unless and until an Event of Default (as defined in Section
5(a)) has occurred. From and after the occurrence and during the continuance of any Event of Default, Interest shall accrue hereunder
at eighteen percent (18.0%) per annum (the "Default Rate") and shall be computed on the basis of a 360-day year
and twelve 30-day months and shall be payable in arrears on the Maturity Date. Accrued and unpaid Interest, if any, shall also
be payable as part of the Outstanding Amount upon any redemption hereunder occurring prior to the Maturity Date. In the event that
such Event of Default is subsequently cured (and no other Event of Default then exists (including, without limitation, for the
Company's failure to pay such Interest at the Default Rate on the Maturity Date)), Interest shall cease to accrue hereunder as
of the calendar day immediately following the date of such cure; provided that the Interest as calculated and unpaid during
the continuance of such Event of Default shall continue to apply to the extent relating to the days after the occurrence of such
Event of Default through and including the date of such cure of such Event of Default.

 

(5)   RIGHTS
UPON EVENT OF DEFAULT.

 

(a)              
Event of Default. Each of the following events shall constitute an "Event of Default" and each of
the events described in clauses (ii) and (iii) shall also constitute a "Bankruptcy Event of Default":

 

(i)                
the Company's failure to pay to the Holder any amount of Principal, Interest or other amounts within five Business Days
of when and as due under this Note or any other Transaction Document (other than on the Maturity Date or due to failure to pay
any Redemption Price hereunder);

 

    - 3 -

     

    

 

(ii)             
the Company's failure to pay to the Holder when and as due any amount due under the Note on the Maturity Date or due upon
failure to pay any Redemption Price hereunder;

 

(iii)           
the Company or any of its Subsidiaries, pursuant to or within the meaning of Title 11, U.S. Code, or any similar Federal,
foreign or state law for the relief of debtors (collectively, "Bankruptcy Law"), (A) commences a voluntary bankruptcy
case, (B) consents to the entry of an order for relief against it in an involuntary bankruptcy case, (C) consents to the appointment
of a receiver, trustee, assignee, liquidator or similar official (a "Custodian"), (D) makes a general assignment
for the benefit of its creditors or (E) admits in writing that it is generally unable to pay its debts as they become due;

 

(iv)           
a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that (A) is for relief against the
Company or any of its Subsidiaries in an involuntary case, (B) appoints a Custodian of the Company or any of its Subsidiaries or
(C) orders the liquidation of the Company or any of its Subsidiaries;

 

(v)            
a final judgment or judgments for the payment of money aggregating in excess of $250,000 are rendered against the Company
or any of its Subsidiaries and which judgments are not, within sixty (60) days after the entry thereof, bonded, discharged or stayed
pending appeal, or are not discharged within sixty (60) days after the expiration of such stay; provided, however,
that any judgment which is covered by insurance or an indemnity from a credit worthy party shall not be included in calculating
the $250,000 amount set forth above so long as the Company provides the Holder a written statement from such insurer or indemnity
provider (which written statement shall be reasonably satisfactory to the Holder) to the effect that such judgment is covered by
insurance or an indemnity and the Company will receive the proceeds of such insurance or indemnity within thirty (30) days of the
issuance of such judgment;

 

(vi)           
other than as specifically set forth in another clause of this Section 5(a), the Company or any of its Subsidiaries breaches
(I) in any material respect any representation, warranty, covenant or other term or condition of any Transaction Document or (II)
in any respect any representation, warranty, covenant or other term or condition of any Transaction Document that is qualified
by materiality or Material Adverse Effect, except, in the case of such a breach of a covenant or other term or condition of any
Transaction Document which is curable, an Event of Default shall be deemed to have occurred only if such breach continues for a
period of an aggregate of five (5) Business Days;

 

(vii)          
any breach or failure in any respect to comply with Section 10 or Section 11 of this Note and such breach or failure
shall have continued for a period of five (5) Business Days or more;

 

(viii)          any
default (following the lapse of any applicable cure period) under, redemption of or acceleration prior to maturity of any Indebtedness
of the Company or any of its Subsidiaries other than with respect to this Note or any Other Notes;

 

    - 4 -

     

    

 

(ix)            
a knowingly false or intentionally inaccurate certification by the Company as to whether any Event of Default has occurred;

 

(x)              
any Material Adverse Effect occurs;

 

(xi)            
(A) the suspension of the Common Stock from trading on an Eligible Market for a period of two (2) consecutive Trading Days
or for more than an aggregate of ten (10) Trading Days in any 365-day period or (B) the failure of the Common Stock to be listed
on an Eligible Market; or

 

(xii)             
any Event of Default (as defined in the Other Notes) occurs with respect to any Other Notes.

 

(b)  
Redemption Right. Upon the occurrence of an Event of Default with respect to this Note or any Other Note, the Company
shall within one (1) Business Day deliver written notice thereof via electronic mail and overnight courier (an "Event of
Default Notice") to the Holder. At any time after the earlier of the Holder's receipt of an Event of Default Notice and
the Holder becoming aware of an Event of Default, the Holder may require the Company to redeem (an "Event of Default Redemption")
all or any portion of this Note by delivering written notice thereof (the "Event of Default Redemption Notice")
to the Company, which Event of Default Redemption Notice shall indicate the portion of this Note the Holder is electing to require
the Company to redeem. Each portion of this Note subject to redemption by the Company pursuant to this Section 5(b) shall be redeemed
by the Company in cash by wire transfer of immediately available funds at a price equal to 100% of the Outstanding Amount being
redeemed in addition to any costs and expenses due hereunder (the "Event of Default Redemption Price"). Redemptions
required by this Section 5(b) shall be made in accordance with the provisions of Section 8. To the extent redemptions required
by this Section 5(b) are deemed or determined by a court of competent jurisdiction to be prepayments of the Note by the Company,
such redemptions shall be deemed to be voluntary prepayments. The parties hereto agree that in the event of the Company's redemption
of any portion of the Note under this Section 5(b), the Holder's damages would be uncertain and difficult to estimate because of
the parties' inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment
opportunity for the Holder. Accordingly, any Event of Default redemption premium due under this Section 5(b) is intended by
the parties to be, and shall be deemed, a reasonable estimate of the Holder's actual loss of its investment opportunity and not
as a penalty.

 

(c)  
Mandatory Redemption upon Bankruptcy Event of Default. Notwithstanding anything to the contrary herein, upon any
Bankruptcy Event of Default, whether occurring prior to or following the Maturity Date, the Company shall immediately pay to the
Holder an amount in cash equal to the Event of Default Redemption Price, in addition to any and all other amounts due hereunder,
without the requirement for any notice or demand or other action by the Holder or any other Person, provided that the Holder may,
in its sole discretion, waive such right to receive payment upon a Bankruptcy Event of Default, in whole or in part, and any such
waiver shall not affect any other rights of the Holder hereunder, including any other rights in respect of such Bankruptcy Event
of Default, and any right to payment of the Event of Default Redemption Price or any other Redemption Price, as applicable.

(6)              
RIGHTS UPON FUNDAMENTAL TRANSACTION AND CHANGE OF CONTROL.

 

(a)              
Assumption. If, at any time while this Note is outstanding, a Fundamental Transaction occurs or is consummated, the
Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the "Successor
Entity") to assume in writing all of the obligations of the Company under this Note in accordance with the provisions
of this Section 6(a) pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by
the Holder (without unreasonable delay) prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to
the Holder in exchange for this Note a security of the Successor Entity evidenced by a written instrument substantially similar
in form and substance to this Note, and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence
of any such Fundamental Transaction, the Successor Entity shall be added to the term "Company" under this Note (so
that from and after the occurrence or consummation of such Fundamental Transaction, each and every provision of this Note referring
to the "Company" shall refer instead to each of the Company and the Successor Entity or Successor Entities, jointly and
severally), and the Successor Entity or Successor Entities, jointly and severally with the Company may exercise every right and
power of the Company prior thereto and the Successor Entity or Successor Entities shall assume all of the obligations of the Company
prior thereto under this Note with the same effect as if the Company and such Successor Entity or Successor Entities, jointly and
severally, had been named as the Company in this Note.

 

(b)              
Redemption Right. The Company shall deliver at least fourteen (14) days prior written notice, but not prior to the
public announcement, of the consummation of a Change of Control via facsimile or electronic mail, followed by overnight courier,
to the Holder (a "Change of Control Notice") setting forth a description
of such transaction in reasonable detail and the anticipated Change of Control Redemption Date if then known. At any time
during the period beginning on the earlier to occur of (x) any written agreement by the Company or any of its Subsidiaries, upon
consummation of which the transaction contemplated thereby would reasonably be expected to result in a Change of Control, (y) the
Holder becoming aware of a Change of Control and (z) the Holder's receipt of a Change of Control Notice and ending twenty-five
(25) Trading Days after the date of the consummation of such Change of Control, the Holder may require the Company to redeem (a
 "Change of Control Redemption") all or any portion of this Note by delivering written notice thereof ("Change
of Control Redemption Notice") to the Company, which Change of Control Redemption Notice shall indicate the Outstanding
Amount the Holder is electing to require the Company to redeem. The portion of this Note subject to redemption pursuant to this
Section 6(b) shall be redeemed by the Company in cash by wire transfer of immediately available funds at a price equal to 100%
of the Outstanding Amount being redeemed (the "Change of Control Redemption Price"). Redemptions required by this
Section 6 shall be made in accordance with the provisions of Section 8 and shall have priority to payments to stockholders
in connection with a Change of Control. To the extent redemptions required by this Section 6(b) are deemed or determined by a court
of competent jurisdiction to be prepayments of the Note by the Company, such redemptions shall be deemed to be voluntary prepayments.

 

(7)               NONCIRCUMVENTION.
The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of Incorporation, 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 of the provisions of this Note and take all action as may be
required to protect the rights of the Holder of this Note.

(8)              
REDEMPTIONS.

 

(a)  
The Company shall deliver the applicable Event of Default Redemption Price to the Holder within three (3) Business Days
after the Company's receipt of the Holder's Event of Default Redemption Notice (the "Event of Default Redemption Date").
If the Holder has submitted a Change of Control Redemption Notice in accordance with Section 6(b), the Company shall deliver the
applicable Change of Control Redemption Price to the Holder within three (3) Business Days after the Company's receipt of such
notice (such date, the "Change of Control Redemption Date"). The Company shall deliver or shall cause to be delivered
to the Holder the applicable Prepayment Price on the applicable Prepayment Date. The Company shall pay the applicable Redemption
Price to the Holder in cash by wire transfer of immediately available funds pursuant to wire instructions provided by the Holder
in writing to the Company on the applicable due date. In the event of a redemption of less than all of the Outstanding Amount of
this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with Section 14(d))
representing the outstanding Principal which has not been redeemed and any accrued Interest
on such Principal which shall be calculated as if no Redemption Notice has been delivered. In the event that the Company
does not pay the applicable Redemption Price to the Holder within the time period required, at any time thereafter and until the
Company pays such unpaid Redemption Price in full, the Holder shall have the option, in lieu of redemption, to require the Company
to promptly return to the Holder all or any portion of this Note representing the Outstanding Amount that was submitted for redemption
and for which the applicable Redemption Price has not been paid. Upon the Company's receipt of such notice, (x) the applicable
Redemption Notice shall be null and void with respect to such Outstanding Amount and (y) the Company shall immediately return this
Note, or issue a new Note (in accordance with Section 14(d)) to the Holder representing such Outstanding Amount to be redeemed.

 

(b)   Redemption by Other Holders. Upon the Company's receipt of notice from any of the holders of the Other Notes for
redemption or repayment as a result of an event or occurrence substantially similar to the events or occurrences described in Section
5(b) or Section 6(b) or pursuant to equivalent provisions set forth in the Other Notes (each, an "Other Redemption Notice"),
the Company shall immediately, but no later than one (1) Business Day of its receipt thereof, forward to the Holder by electronic
mail a copy of such notice. If the Company receives a Redemption Notice and one or more Other Redemption Notices, during the five
(5) Business Day period beginning on and including the date which is two (2) Business Days prior to the Company's receipt of the
Holder's Redemption Notice and ending on and including the date which is two (2) Business Days after the Company's receipt of the
Holder's Redemption Notice and the Company is unable to redeem all Principal, Interest and other amounts designated in such Redemption
Notice and such Other Redemption Notices received during such five (5) Business Day period, then the Company shall redeem a pro
rata amount from the Holder and each holder of the Other Notes (including the Holder) based on the Principal amount of the Notes
submitted for redemption pursuant to such Redemption Notice and such Other Redemption Notices received by the Company during such
five (5) Business Day period.

 

    - 7 -

     

    

 

(c)    Insufficient Assets. If upon a Redemption Date, the assets of the Company are insufficient to pay the applicable
Redemption Price, the Company shall (i) take all appropriate action reasonably within its means to maximize the assets available
for paying the applicable Redemption Price, (ii) redeem out of all such assets available therefor on the applicable Redemption
Date the maximum possible Outstanding Amount that it can redeem on such date, pro rata among the Holder and the holders of the
Other Notes to be redeemed in proportion to the aggregate Principal amount of this Note and the Other Notes outstanding on the
applicable Redemption Date and (iii) following the applicable Redemption Date, at any time and from time to time when additional
assets of the Company become available to redeem the remaining Outstanding Amounts of this Note and the Other Notes, the Company
shall use such assets, at the end of the then current fiscal quarter, to redeem the balance of such Outstanding Amount of this
Note and the Other Notes, or such portion thereof for which assets are then available, on the basis set forth above at the applicable
Redemption Price, and such assets will not be used prior to the end of such fiscal quarter for any other purpose. Interest
on the Principal amount of this Note and the Other Notes that have not been redeemed shall continue to accrue until such time as
the Company redeems this Note and the Other Notes. The Company shall pay to the Holder the applicable Redemption Price without
regard to the legal availability of funds unless expressly prohibited by applicable law or unless the payment of the applicable
Redemption Price could reasonably be expected to result in personal liability to the directors of the Company.

 

(9)              
RANK. All payments due under this Note (i) shall rank pari passu with all Other Notes and (ii) shall be senior
to all other Indebtedness of the Company and its Subsidiaries.

 

(10)              
NEGATIVE COVENANTS. Until all of the Notes have been redeemed or otherwise satisfied in accordance with their terms,
the Company shall not, and the Company shall not permit any of its Subsidiaries without the prior written consent of the Required
Holders to, directly or indirectly:

incur or guarantee, assume or suffer to exist any Indebtedness, other than Permitted Indebtedness;

(c)              
redeem, defease, repurchase, repay or make any payments in respect of, by the payment of cash or cash equivalents (in whole
or in part, whether by way of open market purchases, tender offers, private transactions or otherwise), all or any portion of any
Indebtedness (other than this Note and the Other Notes) of the Company or any other Person, whether by way of payment in respect
of Principal of (or premium, if any) or interest on, such Indebtedness if at the time such payment is due or is otherwise made
or, after giving effect to such payment, an event constituting, or that with the passage of time and without being cured would
constitute, an Event of Default has occurred and is continuing;

 

(d)               redeem,
defease, repurchase, repay or make any payments in respect of, by the payment of cash or cash equivalents (in whole or in
part, whether by way of open market purchases, tender offers, private transactions or otherwise), all or any portion of any
Indebtedness (including, without limitation, Permitted Indebtedness, but not this Note, any Other Notes or the Financing
Lease), by way of payment in respect of principal of (or premium, if any) such Indebtedness. For clarity, such restriction
shall not preclude payment of regularly scheduled interest payments which may accrue under such Permitted Indebtedness;

or unpublished, any patents, patent applications and like protections, including improvements, divisions, continuations, renewals,

law, any applications therefor, whether registered or not, and the goodwill of the business of the Company and its Subsidiaries
connected with and symbolized thereby, know-how, operating manuals, trade secret rights, rights to unpatented inventions, and any
claims for damage by way of any past, present, or future infringement of any of the foregoing;

 

(h)              
enter into, renew, extend or be a party to, any transaction or series of related transactions (including, without limitation,
the purchase, sale, lease, transfer or exchange of property or assets of any kind or the rendering of services of any kind) with
any Affiliate, except for fair consideration and on terms no less favorable to it or its Subsidiaries than would be obtainable
in a comparable arm's length transaction with a Person that is not an Affiliate thereof;

 

(i)                 abandon any Intellectual Property Rights of the Company and/or any of its Subsidiaries that are necessary or material to
the conduct of its business; and

 

(j)

the character of the properties owned or leased by it or in which the transaction of its business makes such qualification
necessary except for those jurisdictions in which the failure to be so qualified or licensed or to be in good standing or in
full force and effect has not resulted in, and would not reasonably be likely to result in, a Material Adverse Effect;

 

    - 9 -

     

    

 

(b)

(12)          
CHANGING THE TERMS OF THIS NOTE. The (a) consent of the Company and (b) affirmative vote at a meeting duly called
for such purpose or the written consent without a meeting of the Required Holders shall be required for any change or amendment
of any provision of this Note or any of the Other Notes. The affirmative vote at a meeting duly called for such purpose or the
written consent without a meeting of the Required Holders shall be required for any waiver of any provision of this Note or any
of the Other Notes. Any change, amendment or waiver by the Company and the Required Holders shall be binding on the Holder of this
Note and all holders of the Other Notes; provided, however, that no such change, waiver or, as applied to any of the Notes held
by any particular holder of Notes, shall, without the written consent of that particular holder, (i) reduce the amount of Principal,
reduce the amount of accrued and unpaid Interest, or extend the Maturity Date, of the Notes, (ii) disproportionally and adversely
affect any rights under the Notes of any holder of Notes; or (iii) modify any of the provisions of, or impair the right of any
holder of Notes under, this Section 12. No consideration (other than reimbursement of legal fees) shall be offered or paid to any
Person to amend or consent to a waiver or modification of any provision of the Notes unless the same consideration also is offered
to all holders of Notes.

 

(13)

than the entire outstanding Principal is being transferred, a new Note (in accordance with Section 14(d)) to the Holder
representing the outstanding Principal not being transferred. The Holder and any assignee, by acceptance of this Note,
acknowledge and agree that, by reason of the provision of Section 3, following redemption of any portion of this Note, the
outstanding Principal represented by this Note may be less than the Principal stated on the face of this Note.

Lost, Stolen or Mutilated Note. Upon receipt by the Company of evidence reasonably satisfactory to the Company of
the loss, theft, destruction or mutilation of this Note, and, in the case of loss, theft or destruction, of any indemnification
undertaking by the Holder to the Company in customary form (but without any obligation to post a surety or other bond) and, in

Note Exchangeable for Different Denominations. This Note is exchangeable, upon the surrender hereof by the Holder
at the principal office of the Company, for a new Note or Notes (in accordance with Section 14(d)) representing in the aggregate
the outstanding Principal of this Note, and each such new Note will represent such portion of such outstanding Principal as is
designated by the Holder at the time of such surrender.

remaining outstanding (or in the case of a new Note being issued pursuant to Section 14(a) or Section 14(c), the Principal designated

prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable,
and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Note
so long as this Note as so modified continues to express, without material change, the original intentions of the parties as to
the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially
impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would
otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid
or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited,
