 ALPHA INNOTECH CORP. 
 SENIOR CONVERTIBLE NOTE 
  

			
	Issuance Date: July     , 2006	  	Principal: U.S. $            

 FOR VALUE RECEIVED, ALPHA INNOTECH CORP., a Delaware corporation (the
“Company”), hereby promises to pay to the order of
                                        
         or registered assigns (“Holder”) the amount set out above as the Principal (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise, the
“Principal”) when due, whether upon the Maturity Date (as defined below), acceleration, redemption or otherwise (in each case in accordance with the terms hereof) and to pay interest (“Interest”) on any outstanding
Principal at the rate of 3% per annum, compounded annually (the “Interest Rate”) unless otherwise provided herein, from the date set out above as the Issuance Date (the “Issuance Date”) until the same becomes
due and payable, whether upon, the Maturity Date, acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof). This Senior Convertible Note (including all Senior Convertible Notes issued in exchange, transfer
or replacement of, the “Note”) is one of an issue of Senior Convertible Notes (collectively, the “Notes” and such other Senior Convertible Notes, the “Other Notes”) issued on the Issuance Date
pursuant to the Securities Purchase Agreement (as defined below). Certain capitalized terms are defined in Section 23. 
 1.
MATURITY. On the Maturity Date, the Holder shall surrender this Note to the Company and the Company shall pay to the Holder an amount in cash representing all outstanding Principal and accrued and unpaid Interest, if any. The “Original
Maturity Date” shall be July     , 2011, as may be extended at the sole option of the Holder in the event that, and for so long as, an Event of Default (as defined in Section 4(a)) shall have occurred and be
continuing or any event shall have occurred and be continuing which with the passage of time and the failure to cure would result in a Conversion Failure. 
 2. INTEREST; INTEREST DATE. Interest on this Note shall commence accruing on the Issuance Date and shall be computed on the basis of a 365-day year and actual days elapsed and shall be payable on the Maturity
Date (the “Interest Date”). 
 3. CONVERSION OF NOTES. This Note shall be convertible into shares of the
Company’s common stock, par value $0.01 per share (the “Common Stock”), on the terms and conditions set forth in this Section 3. 
 (a) Conversion Right. Subject to the provisions of Section 3(d), at any time or times on or after the Issuance Date, the Holder shall be entitled to convert any portion of the outstanding and unpaid
Conversion Amount (as defined below) into fully paid and nonassessable shares of Common Stock in accordance with Section 3(c), at the Conversion Rate (as defined below). The Company shall not issue any fraction of a share of Common Stock upon
any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall pay to the Holder an amount in cash equal to the value of such fractional share based on the closing price of the Common Stock
on the last trading day prior to 








 
the conversion. The Company shall pay any and all documentary, stamp and similar taxes that may be payable with respect to the issuance and delivery of
Common Stock upon conversion of any Conversion Amount. The Company shall not, however, be required to pay any such tax which may be payable in respect of any transfer of Securities involved in the issue and delivery of the Common Stock in any name
other than that of the Holder. 
 (b) Conversion Rate. The number of shares of Common Stock issuable upon conversion of any Conversion
Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”). 
 (i) “Conversion Amount” means the Principal to be converted, redeemed or otherwise with respect to which this determination is being
made, plus all accrued and unpaid Interest on the Principal being converted. 
 (ii) “Conversion Price” means, subject to
adjustment as provided herein, $1.60. 
 (c) Mechanics of Conversion. 
 (i) Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion Date”), the
Holder shall (A) transmit by facsimile (or otherwise deliver), for receipt on or prior to 4:59 p.m., New York Time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the
“Conversion Notice”) to the Company and (B) if required by Section 3(c)(iii), deliver this Note to a common carrier for delivery to the Company as soon as practicable on or following such date (or a customary
indemnification undertaking with respect to this Note in the case of its loss, theft or destruction). On or before the close of the business on the first Business Day following the date of receipt of a Conversion Notice, the Company shall transmit
by facsimile a confirmation of receipt of such Conversion Notice to the Holder and the Company’s transfer agent (the “Transfer Agent”). On or before the second Business Day following the date of receipt of a Conversion Notice
(the “Share Delivery Date”), the Company’s transfer agent shall issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of
shares of Common Stock to which the Holder shall be entitled. If this Note is physically surrendered for conversion as required by Section 3(c)(iii) and the outstanding Principal of this Note is greater than the Principal being converted, then
the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Note and at its own expense, issue and deliver to the Holder a new Note representing the outstanding Principal not converted and
otherwise in substantially the same form as this Note. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of
Common Stock on the Conversion Date. 
 (ii) Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion
of any portion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted or (B) the
Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) 

  

 2 








 
requesting physical surrender and reissue of this Note. The Holder and the Company shall maintain records showing the Principal converted and the dates of
such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon conversion. 
 (d) Principal Market Regulation. The Company shall not be obligated to issue any shares of Common Stock upon conversion of this Note if the
issuance of such shares of Common Stock would exceed that number of shares of Common Stock which the Company may issue upon conversion of the Notes without breaching the Company’s obligations under the rules or regulations of the Principal
Market (the “Exchange Cap”), except that such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as required by the applicable rules of the Principal Market for issuances of
Common Stock in excess of such amount (Company shall be required to obtain such approval if the issuance would exceed that number of shares of Common Stock which the Company may issue upon conversion of the Notes if it breaches the Company’s
obligations under the Exchange Cap) or (B) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion shall be reasonably satisfactory to the holders of the Notes representing at least
a majority of the principal amounts of the Notes then outstanding. Until such approval or written opinion is obtained, no purchaser of the Notes pursuant to the Securities Purchase Agreement (the “Purchasers”) shall be issued, upon
conversion of Notes, shares of Common Stock in an amount greater than the product of the Exchange Cap multiplied by a fraction, the numerator of which is the principal amount of Notes issued to such Purchaser pursuant to the Securities Purchase
Agreement on the Issuance Date and the denominator of which is the aggregate principal amount of all Notes issued to the Purchasers pursuant to the Securities Purchase Agreement on the Issuance Date (with respect to each Purchaser, the
“Exchange Cap Allocation”). In the event that any Purchaser shall sell or otherwise transfer any of such Purchaser’s Notes, the transferee shall be allocated a pro rata portion of such Purchaser’s Exchange Cap Allocation,
and the restrictions of the prior sentence shall apply to such transferee with respect to the portion of the Exchange Cap Allocation allocated to such transferee. 
 (e) Mandatory Conversion. If the closing price of the Common Stock has been at or above $2.50 (as adjusted for stock splits, stock dividends, recapitalizations and like transactions), for at least 30
consecutive Business Days, then any remaining Principal and accrued and unpaid Interest under the Note shall automatically convert into Common Stock in accordance with this Section 3; provided that Holder shall not have to complete such
conversion until such time as: (i) the amount of Common Stock outstanding is equal to the Required Reserve Amount; and (ii) conversion would not be impaired pursuant to Section 3(d) hereof. 
 4. RIGHTS UPON EVENT OF DEFAULT. 
 (a)
Event of Default. Each of the following events shall constitute an “Event of Default”: 
 (i) default in the payment
of the Principal and unpaid accrued Interest of this Note within five (5) Business Days of becoming due and payable; 
  

 3 








 (ii) any other default by the Company of the performance of any of its obligations or any breach by the
Company of any representations or covenants (provided that a default of any such covenant is not otherwise defined as an Event of Default under this Section 4(a)) hereunder or under the Securities Purchase Agreement (provided that the
representations and warranties under the Securities Purchase Agreement shall only survive for one year from the date of execution of the Securities Purchase Agreement) upon 10 days notice from the Holder to the Company; 
 (iii) the Company shall make an assignment for the benefit of creditors, file a petition in bankruptcy, consent to entry of an order for relief against
it in an involuntary case, be adjudicated insolvent or bankrupt, petition or apply to any tribunal for the appointment of any receiver, trustee or similar official for it or a substantial part of its assets, or commence any proceeding under any
bankruptcy, reorganization, arrangement, readjustment of debt, dissolution or liquidation law or statute of any jurisdiction, whether now or hereafter in effect; there shall occur the appointment of a receiver, trustee, assignee, liquidator,
custodian or similar official of it or a substantial part of its assets; or there shall have been filed any such petition or application or any such proceeding shall have been commenced against it, which remains undismissed for a period of 60 days
or more; the Company by any act or omission shall indicate its consent to, approval of or acquiescence in any such petition, application or proceeding or the appointment of any trustee for it or any substantial part of any of its properties; or

 (iv) a court of competent jurisdiction shall enter an order or decree under any Bankruptcy Law that is for relief against the Company in
an involuntary case, appoints a receiver, trustee, assignee, liquidator or similar official of the Company or for any substantial part of its property, or orders the liquidation of the Company; and the order or decree remains unstayed and in effect
for 30 days. 
 (b) Redemption Right Upon Event of Default. Promptly after the occurrence of an Event of Default with respect to this
Note or any Other Note, the Company shall deliver written notice thereof via facsimile and overnight courier (an “Event of Default Notice”) to the Holder and the holders of the Other Notes. 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 all or any portion of the Notes 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 the Notes that the Holder is electing to cause to be redeemed. Notwithstanding the immediately preceding sentence to the
contrary, in the case of an Event of Default pursuant to Section 4(a)(iii) above, all amounts of Principal and Interest accrued under this Note shall be deemed automatically due, payable, and collectible, without need for any Notice.

 (c) Default Rate of Interest. Notwithstanding the immediately preceding terms of this section, upon the occurrence of an Event of
Default, all amounts due and owing under this Note shall bear interest at a rate of ten percent (10%) per annum from the date of such default until all such amounts are paid in full. 
 5. RIGHTS UPON CERTAIN CORPORATE EVENTS. Prior to the consummation of any recapitalization, reorganization, consolidation, merger, spin-off or
other business 

  

 4 








 
combination (including, without limitation, a Change of Control (defined below)) pursuant to which holders of Common Stock are entitled to receive securities
or other assets with respect to or in exchange for Common Stock (a “Corporate Event”), the Company shall make appropriate provision at the Holder’s option to insure that the Holder will thereafter have the right to receive upon
a conversion of this Note: (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares
of Common Stock been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note); or (ii) in lieu of the shares of Common Stock otherwise
receivable upon such conversion, such securities or other assets received by the holders of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note
initially been issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Rate. Provision made pursuant to the preceding
sentence shall be in a form and substance satisfactory to the Holders with Notes representing a majority in interest of the Principal outstanding (the “Required Holders”). The provisions of this Section shall apply similarly and
equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption of this Note. Each of the following events shall constitute a “Change of Control”: 
 (i) any sale of all or substantially all of the assets of the Company to a third party; 
 (ii) any merger of the Company with or into another corporation in which holders of Common Stock immediately prior to the consummation of the merger do
not control 50% of the voting power of the surviving corporation; or 
 (iii) the acquisition by any “person” or “group”
of persons (as such terms are used in Section 13(d) and 14(d) of the Securities and Exchange Act of 1934, as amended, and the related regulations) who have an expressed intent to control the affairs of the Company of more than 50% of the
outstanding Common Stock of the Company. 
 6. ADJUSTMENT OF CONVERSION PRICE UPON SUBDIVISION OR COMBINATION OF COMMON STOCK. If the
Company at any time on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization or otherwise) one or more classes of its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in
effect immediately prior to such subdivision will be proportionately reduced. If the Company at any time on or after the Issuance Date combines (by combination, reverse stock split or otherwise) one or more classes of its outstanding shares of
Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will be proportionately increased. 
 7. PREPAYMENT. With respect to each Holder, this Note may only be prepaid (notwithstanding acceleration or other remedy following an Event of Default) in whole or in part beginning on the second anniversary of
the Issuance Date; provided, however, that if the Note is prepaid prior to the third anniversary of the Issuance Date, the Company shall pay to the Holder 

  

 5 








 
a fee equal to 3% of the Principal then outstanding and prepaid (the “Prepayment Fee”) with such Prepayment Fee declining 1% per year
to par at Maturity Date. The Company will provide the Holder with prior written notice (“Prepayment Notice”) of its intent to pre-pay the Note at least 20 days before the Company’s intended date of prepayment (“Intended
Prepayment Date”). Upon receipt of a Prepayment Notice, the Holder may exercise any of the conversion rights available to the Holder pursuant to this Note by providing notice to the Company at least 5 days before the Intended Prepayment
Date. 
 8. NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate of
Incorporation or through any reorganization, transfer of assets, consolidation, merger, 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. 
 9. RESERVATION OF AUTHORIZED SHARES. The Company shall initially reserve out of its authorized and unissued Common Stock a number of shares of Common Stock for each of the Notes equal to 100% of the Conversion
Rate with respect to the Conversion Amount of each such Note as of the Issuance Date. Thereafter, the Company, so long as any of the Notes are outstanding, shall take all action necessary to reserve and keep available out of its authorized and
unissued Common Stock, solely for the purpose of effecting the conversion of the Notes, 100% of the number of shares of Common Stock as shall from time to time be necessary to effect the conversion of all of the Notes then outstanding (the
“Required Reserve Amount”). 
 10. HOLDER’S REDEMPTIONS. In the event that the Holder has sent an Event of
Default Redemption Notice to the Company pursuant to Section 4(b) (a “Redemption Notice”), or if the note is deemed automatically redeemed due to a default under Section 4(a)(iii) to the Holder shall promptly submit this Note to the
Company. The Company shall deliver the applicable Event of Default Redemption Price to the Holder within 10 Business Days after the Company’s receipt of the Holder’s Redemption Notice. In the event of a redemption of less than all of the
Conversion Amount of this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note representing the outstanding Principal which has not been redeemed. In the event that the Company does not pay the Event of Default
Redemption Price (the “Redemption Price”), to the Holder (or deliver any Common Stock to be issued pursuant to a Redemption Notice) within the time period required, at any time thereafter and until the Company pays such unpaid
Redemption Price (and issues any Common Stock required pursuant to a Redemption Notice) 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 Conversion Amount that was submitted for redemption and for which the applicable Redemption Price (or any Common Stock required to be issued pursuant to a Redemption Notice) has not been paid. Upon the Company’s receipt of such
notice: (x) the Redemption Notice shall be null and void with respect to such Conversion Amount; and (y) the Company shall immediately return this Note, or issue a new Note to the Holder representing such Conversion Amount.

 11. STATUS OF DEBT. 
 (a) Agreement to Eliminate Senior Debt to Third Parties. By issuing this Note, the Company for itself and its successors and assigns, and for its Subsidiaries and the successors and assigns of such
Subsidiaries, agrees, and the Holder, by its acceptance of this Note, shall be deemed to have agreed, that this Note shall be subject to the provisions of this Section 11 and, to the extent and in the manner hereinafter set forth in this
Section 11, the indebtedness represented by this Note and the payment of the Principal and Interest, any redemption amount, liquidated damages, fees, expenses or any other amounts in respect of this Note are subordinate in right of payment only
to the prior payment in full in cash of (i) all Senior Debt now outstanding and (ii) the Future Permitted Senior Debt (as defined in Section 13(b) below). The Holder shall be entitled to receive payment in full in cash before any of
the Subordinated Indebtedness or any other Indebtedness save Senior Debt or Future Permitted Senior Debt (including interest after the commencement of any proceeding under any Bankruptcy Law at the agreed upon rate before any other creditor or
Credit Party shall be entitled to receive any payment with respect to any indebtedness other than the Senior Debt or the Future Permitted Senior Debt (“Holder’s Rights”). 
 (b) Liquidation; Dissolution; Bankruptcy. 
 (i) The holders of Senior Debt and Future Permitted Senior Debt shall be entitled to receive payment in full in cash of all Senior Debt or Future Permitted Senior Debt (including interest after the commencement of any proceeding under any
Bankruptcy Law at the rate specified in the documentation for the applicable Senior Debt or Future Permitted Senior Debt) before the Holder shall be entitled to receive any payment with respect to any indebtedness other than the Senior Debt or the
Future Permitted Senior Debt (the “Subordinated Indebtedness”), however, the Holder shall be entitled to the Holder’s Rights in the event of any distribution to creditors of any of the Company or its Subsidiaries (each, a
“Credit Party”) in (A) any sale, liquidation, winding-up or dissolution of such Credit Party; (B) any bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to such Credit Party or its
property; (C) any assignment by such Credit Party for the benefit of its creditors; or (D) any marshaling of any Credit Party’s assets and liabilities (each a “Bankruptcy Event”). 
 (ii) In the event of any distribution, division or application, partial or complete, voluntary or involuntary, by operation of law or otherwise, of all
or any part of the assets of any Credit Party or the proceeds thereof to creditors of any Credit Party upon any Indebtedness of such Credit Party, by reason of any Bankruptcy Event, then and in any such event, any payment or distribution of any kind
or character, either in cash, securities or other property, which shall be payable or deliverable to the Holder upon or with respect to any or all Subordinated Indebtedness shall be paid or delivered directly to an agent for the Senior Debt or
Future Permitted Senior Debt (the “Agent”) for application against the Senior Debt or Future Permitted Senior Debt, whether due or not due, in a manner which the Agent, in its sole discretion, shall determine, until such Senior Debt
or Future Permitted Senior Debt shall have been fully paid in cash and all commitments thereunder have terminated. The Holder hereby irrevocably authorizes and empowers the Agent to ask for, demand, sue for, collect, and receive for every such
payment or distribution and give acquittance therefor, and to file claims (and proofs of claims) and take such other actions in the Agent’s own name or in the name of the Holder as the Agent may deem necessary or advisable for the enforcement
of the terms of this Section 11. 
  

 7 








 (iii) The Holder agrees to execute, verify, deliver and file any proofs of claim in respect of
Subordinated Indebtedness reasonably requested by the Agent in connection with any Bankruptcy Event and upon the Holder’s failure to provide such reasonable proofs of claim, hereby irrevocably authorizes, empowers and appoints Agent as its
agent and attorney-in-fact to (i) execute, verify, deliver and file such proofs of claim upon the failure of the Holder promptly to do so prior to five (5) Business Days before the expiration of the time to file any such proof of claim and
(ii) vote such claim in any such Bankruptcy Event upon the failure of the Holder to do so prior to five (5) Business Days before the expiration of the time to vote any such claim; provided the Agent shall have no obligation to execute,
verify, deliver, file and/or vote any such proof of claim. In the event that the Agent votes any claim in accordance with the authority granted hereby, the Holder shall not be entitled to change or withdraw such vote. The Agent shall be responsible
for providing the Holder with notice of any action taken on behalf of the Holder. 
 (c) Redemption upon Event of Default. The Holder
shall give the Agent at least three (3) Business Days prior notice of its intention to exercise its redemption rights upon the occurrence of an Event of Default. 
 (d) No Amendment of Subordinated Indebtedness. Neither the Holder nor any Credit Party will, without the prior written consent of the Agent, amend or modify (i) this Section 11 or the definition of
any capitalized term used in this Section 11 or (ii) any provision of the Securities Purchase Agreement or the other Securities Purchase Documents if such amendment or modification would (A) move forward the date of any redemption or
payment or increase the principal amount of or the rate of interest applicable to the Subordinated Indebtedness or (B) result in the covenants contained therein being materially more restrictive in the aggregate on the Holder or any Credit
Party prior to the effectiveness of such amendment or modification. 
 (e) No Impairment of Subordination. No right of the Agent,
Holder, any lender or any future holder of any Senior Debt or Future Permitted Senior Debt to enforce the subordination as provided in this Section 11 shall at any time in any way be prejudiced or impaired by any act or failure to act on the
part of the Holder or any Credit Party or any act or failure to act by the Agent, any lender or any such holder, or by any noncompliance by any Credit Party with the terms of this Section 11, regardless of any knowledge thereof which the Agent
or any lender may have or with which it may otherwise be charged. 
 (f) Subrogation. Subject to payment in full in cash of all Senior
Debt and Future Permitted Senior Debt and the termination of all commitments thereunder, the rights of the Holder shall be subrogated to the rights of the holders of Senior Debt and Future Permitted Senior Debt to receive payments or distributions
of the assets of any Credit Party made on such Senior Debt or Future Permitted Senior Debt until all principal and interest on this Note shall be paid in full in cash; and for purposes of such subrogation, no payments or distributions to the holders
of Senior Debt or Future Permitted Senior Debt of any cash, property or securities to which the Holder would be entitled except for the subordination provisions of this Section 11 shall, as between the Holder and the Company and/or its
creditors other than the holders of the Senior Debt or Future Permitted Senior Debt, be deemed to be a payment on account of the Senior Debt or Future Permitted Senior Debt. 
  

 8 








 (g) Conversion Rights. Nothing contained in this Section 11 or elsewhere in this Note is
intended to or shall impair, as among the Company, its creditors, including the holders of Senior Debt and Future Permitted Senior Debt, and the Holder, the right, which is absolute and unconditional, of the Holder to convert this Note into shares
of Common Stock or rights to acquire shares of Common Stock in accordance with the terms hereof. 
 (h) Rights of Holder Unimpaired.
The provisions of this Section 11 are and are intended solely for the purposes of defining the relative rights of the Holder and the holders of Senior Debt and Future Permitted Senior Debt and nothing in this Section 11 shall impair, as
between the Company and the Holder, the obligation of the Company, which is unconditional and absolute, to pay to the Holder the Principal (and premium, if any) and Interest, in accordance with the terms of this Note. 
 (i) Subordination May Not Be Impaired by any Credit Party. No right of any holder of Permitted Indebtedness to enforce the subordination of the
Subordinated Indebtedness shall be impaired by any act or failure to act by any Credit Party or the Holder or by the failure of any Credit Party or the Holder to comply with the terms of this Section 11. 
 (j) Reliance by Holder. Upon any payment or distribution of assets of any Credit Party referred to in this Section 11, the Holder shall be
entitled to rely upon any order or decree made by any court of competent jurisdiction or upon any certificate of the Agent or of the liquidating trustee or agent or other Person making any distribution to the Holder for the purpose of ascertaining
the Persons entitled to participate in such distribution, the holders of the Permitted Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Section 11. 
 (k) Reliance by Holders of Senior Debt and Future Permitted Senior Debt. The Holder
acknowledges and agrees that (i) each holder of Senior Debt and Future Permitted Senior Debt is an intended third-party beneficiary of the terms of the Section 11 and (ii) the foregoing provisions of this Section 11 are, and are
intended to be, an inducement and consideration to each holder of Senior Debt and Future Permitted Senior Debt , whether such Senior Debt or Future Permitted Senior Debt was created or acquired before or after the date hereof, to acquire or continue
to hold such Senior Debt or Future Permitted Senior Debt and such holder of Senior Debt or Future Permitted Senior Debt shall be deemed conclusively to have relied on such provisions in acquiring or continuing to hold such Senior Debt or Future
Permitted Senior Debt. 
 (l) Applicability. The terms of this Section 11 shall be applicable both before and after the filing of
any petition by or against any Credit Party under any Bankruptcy Law, and all allocations of payments between the holders of the Senior Debt and Future Permitted Senior Debt, on the one hand, and the Holder, on the other hand, shall continue to be
made after the filing thereof in accordance with this Section 11. 
 12. VOTING RIGHTS. The Holder shall have no voting rights as
the holder of this Note, except as required by law, including but not limited to the General Corporation Law of the State of Delaware, and as expressly provided in this Note.

 13. RANK; ADDITIONAL INDEBTEDNESS. 
 (a) Rank. All payments due under this Note: (i) shall be subordinate in right of payment to the prior payment of all existing Senior Debt and
the Future Permitted Senior Debt, without duplication; and (ii) shall be senior to all other Indebtedness of the Company and its Subsidiaries. The Holder agrees and covenants that this Note will be subordinate to the Future Permitted Senior
Debt, as contemplated in Section 13(b) below, and the Holder further agrees and covenants to enter into a subordination agreement in connection with any such working capital facility. The Company agrees that other than the Senior Debt, the
Future Permitted Senior Debt, any liens permitted under the Future Permitted Senior Debt (provided that in no event shall the amount of Future Permitted Senior Debt plus the amount of liens permitted under the Future Permitted Senior Debt be greater
than $5 million), or as required by law, no current or future note holder, purchaser or entity has or will have a security interest, lien or levy upon any assets, intellectual property, real property or any other property or receivables of the
Company which shall be senior to that of the Holder. Holder acknowledges that it does not currently have a security interest in any of the assets or property of the Company. 
 (b) Incurrence of Senior Debt. So long as this Note is outstanding, the Company shall not, and the Company shall not permit any of its
Subsidiaries to, directly or indirectly, incur or guarantee, assume or suffer to exist any Indebtedness which shall rank senior to the Notes other than the prior existing Senior Debt or, upon the prior written consent of the Required Holders, any
indebtedness in connection with one or more working capital facilities secured by the Company’s assets; provided, that in no event shall the aggregate of all such working capital facilities exceed $5 million (the “Future Permitted
Senior Debt”). 
 14. TRANSFER. This Note may be offered, sold, assigned or transferred by the Holder in minimum
denominations of $250,000 with the consent of the Company; provided, however, that such consent shall not be unreasonably withheld, subject to the Securities Act of 1933, as amended, and the Rules and Regulations promulgated thereunder and the
Securities Purchase Agreement; provided however that this Note may not be transferred to any person who (a) is a competitor of the Company or (b) is engaged in or has threatened material litigation against the Company, in each case as determined by
the Board of Directors of the Company in good faith. Notwithstanding the foregoing, in case of an Event of Default, this Note may be transferred without regard to any of the foregoing limitations. 
 15. VOTE TO ISSUE, OR CHANGE THE TERMS OF, 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 change, amendment or waiver related to this Note or the Other Notes; provided, however, that no such change, amendment or waiver, as applied to any particular holder of Notes, shall: (i)
without the consent of that particular holder, extend the maturity of the Note, reduce the interest rate, extend the time of payment of interest thereon, or reduce the principal amount thereof or premium, if any, thereon, or reduce any amount
payable on redemption or repurchase thereof or affect any amounts due to any holder; or (ii) without the consent of the holders of all Notes then outstanding, reduce the aforesaid percentage of Notes, the holders of which are required to consent to
any such change, amendment or waiver.

 16. REISSUANCE OF THIS NOTE. 
 (a) Transfer. If this Note is to be transferred, the Holder shall surrender this Note to the Company, whereupon the Company will forthwith issue
and deliver upon the order of the Holder a new Note, registered as the Holder may request, representing the outstanding Principal being transferred by the Holder and, if less then the entire outstanding Principal is being transferred, a new Note 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 provisions of Section 3(c)(iii) and this Section 16(a),
following conversion or 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. The Company shall not be obligated to pay any documentary, stamp or
similar taxes that may be payable with respect to any transfer under this Section 16(a). 
 (b) 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 an indemnification undertaking by the Holder to the Company
in customary form and, in the case of mutilation, upon surrender and cancellation of this Note, the Company shall execute and deliver to the Holder a new Note representing the outstanding Principal. 
 (c) 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 principal amounts of at least $100,000) 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. 
 (d) Issuance of New Notes. Whenever the Company is required to issue a new Note
pursuant to the terms of this Note, such new Note: (i) shall be of like tenor with this Note; (ii) shall represent, as indicated on the face of such new Note, the Principal remaining outstanding (or in the case of a new Note being issued
pursuant to Section 16(a) or Section 16(c), the Principal designated by the Holder which, when added to the principal represented by the other new Notes issued in connection with such issuance, does not exceed the Principal remaining
outstanding under this Note immediately prior to such issuance of new Notes); (iii) shall have an issuance date, as indicated on the face of such new Note, which is the same as the Issuance Date of this Note; (iv) shall have the same
rights and conditions as this Note; and (v) shall represent accrued Interest on the Principal and Interest of this Note, from the Issuance Date. 
 17. REMEDIES, CHARACTERIZATIONS, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note and the
Securities Purchase Agreement, at law or in equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the Holder’s right to pursue actual and consequential damages for any failure by the
Company to comply with the terms of this Note. Amounts set forth or provided for herein with respect to payments, conversion and the like (and the computation thereof) shall be the amounts to be received by the Holder and shall not, except as
expressly provided herein, be subject to any other obligation of the Company (or the performance thereof). The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law
for any such breach may be inadequate. The Company 

  

 11 








 
therefore agrees that, in the event of any such breach or threatened breach, the Holder shall be entitled, in addition to all other available remedies, to an
injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. The Company shall pay the Holder for any costs associated in obtaining such injunction or remedy if the Holder
successfully prevails in obtaining such injunction or other remedy, and the Holder shall pay the Company for any costs associated in defending such injunction or remedy if the Company successfully prevails in defending such injunction or other
remedy. 
 18. PAYMENT OF COLLECTION, ENFORCEMENT AND OTHER COSTS. If (a) this Note is placed in the hands of an attorney for
collection or enforcement or is collected or enforced through any legal proceeding or the Holder otherwise takes action to collect amounts due under this Note or to enforce the provisions of this Note or (b) there occurs any bankruptcy,
reorganization, receivership of the Company or other proceedings affecting Company creditors’ rights and involving a claim under this Note, then the Company shall pay the costs incurred by the Holder for such collection, enforcement or action
or in connection with such bankruptcy, reorganization, receivership or other proceeding, including, but not limited to, attorneys’ fees and disbursements. 
 19. CONSTRUCTION; HEADINGS. This Note shall be deemed to be jointly drafted by the Company and all the Purchasers (as defined in the Securities Purchase Agreement) and shall not be construed against any person
as the drafter hereof. The headings of this Note are for convenience of reference and shall not form part of, or affect the interpretation of, this Note. 
 20. 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 privilege. 
 21.
NOTICES; PAYMENTS. 
 (a) Notices. Whenever notice is required to be given under this Note, unless otherwise provided herein,
such notice shall be given in accordance with Section 8 of the Securities Purchase Agreement. The Company shall provide the Holder with prompt written notice of all actions taken pursuant to this Note, including in reasonable detail a
description of such action and the reason therefore. Without limiting the generality of the foregoing, the Company will give written notice to the Holder: (i) immediately upon any adjustment of the Conversion Price (the “Conversion
Price Notice”), setting forth in reasonable detail, and certifying, the calculation of such adjustment, which shall be conclusive absent manifest error, as commercially reasonably determined by the Holder in good faith, and provided that if
the Holder determines any manifest error, the Holder shall provide written notice of such error within two (2) Business Days of receiving the Conversion Price Notice; and (ii) at least 20 days prior to the date on which the Company closes
its books or takes a record: (A) with respect to any dividend or distribution upon the Common Stock; (B) with respect to any pro rata subscription offer to holders of Common Stock; or (C) for determining rights to vote with respect to
any Change of Control, dissolution or liquidation, provided in each case that such information shall be made known to the public prior to or in conjunction with such notice being provided to the Holder.

 (b) Payments. Whenever any payment of cash is to be made by the Company to any Person pursuant to
this Note, such payment shall be made in lawful money of the United States of America via wire transfer of immediately available funds pursuant to the Holder’s wire transfer instructions, which are being provided to the Company on the Issuance
Date. 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 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. 
 22. CANCELLATION. After all Principal, accrued Interest and other amounts at any time owed on this Note have been paid in full, this Note shall
automatically be deemed canceled, shall be surrendered to the Company for cancellation and shall not be reissued. 
 23. WAIVER OF
NOTICE. To the extent permitted by law, the Company hereby waives demand, notice, protest and all other demands and notices in connection with the delivery, acceptance, performance, default or enforcement of this Note and the Securities Purchase
Agreement. 
 24. GOVERNING LAW. This Note shall be construed and enforced in accordance with, and all questions concerning the
construction, validity, interpretation and performance of this Note shall be governed by, the internal laws of the State of California, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of
