	1.	CREATION OF SECURITY INTEREST 

 Debtor grants to
Secured Party, its successors and assigns, a security interest in and against all property listed on any collateral schedule now or in the future annexed to or made a part of this Agreement (“Collateral Schedule”), and in and against all
additions, attachments, accessories and accessions to such property, all substitutions, replacements or exchanges therefore, and all insurance and/or other proceeds thereof (all such property is individually and collectively called the
“Collateral”). This security interest is given to secure the payment and performance of certain Promissory Notes made by Debtor in favor of Secured Party from time to time identified on any Collateral Schedule (collectively
“Notes” and each a “Note”), and all obligations under this Agreement and any obligations under any renewals, extensions and modifications of such Notes or this Agreement (such Notes and obligations are called the
“Indebtedness”). 
  

	2.	REPRESENTATIONS, WARRANTIES AND COVENANTS OF DEBTOR 

 Debtor represents, warrants and covenants as of the date of this Agreement and as of the date of each Collateral Schedule that: 
  

	 	(a)	Due Organization. Debtor’s exact legal name is as set forth in the preamble of this Agreement and Debtor is, and will remain, duly organized, existing and
in good standing under the laws of the State set forth in the preamble of this Agreement, has its chief executive offices at the location specified in the preamble and is, and will remain duly qualified and licensed in every jurisdiction wherever
necessary to carry on its business and operations; 

  

	 	(b)	Power and Capacity to Enter Into and Perform Obligations. Debtor has adequate power and capacity to enter into, and to perform its obligations under this
Agreement, each Collateral Schedule, each Note and any other documents evidencing, or given in connection with, any of the Indebtedness (all of the foregoing are called the “Debt Documents”); 

  

	 	(c)	Due Authorization. This Agreement and the other Debt Documents have been duly authorized, executed and delivered by Debtor and constitute legal, valid and
binding agreements enforceable in accordance with their terms, except to the extent that the enforcement of remedies may be limited under applicable bankruptcy and insolvency laws; 

  

 1 

	 	(d)	Approvals and Consents. No approval, consent or withholding of objections is required from any governmental authority or instrumentality with respect to the
entry into, or performance by Debtor of any of the Debt Documents, except any already obtained; 

  

	 	(e)	No Violations or Defaults. The entry into, and performance by, Debtor of the Debt Documents will not (i) violate any of the organizational documents of
Debtor or any judgment, order, law or regulation applicable to Debtor, or (ii) result in any breach of or constitute a default under any contract to which Debtor is a party, or result in the creation of any lien, claim or encumbrance on any of
Debtor’s property (except for liens in favor of Secured Party) pursuant to any indenture, mortgage, deed of trust, bank loan, credit agreement, or other agreement or instrument to which Debtor is a party; 

  

	 	(f)	Litigation. There are no suits or proceedings pending in court or before any commission, board or other administrative agency against or affecting Debtor which
could, in the aggregate have a material adverse effect on Debtor, its business or operations, or its ability to perform its obligations under the Debt Documents, nor does Debtor have reason to believe that any such suits or proceedings are
threatened; 

  

	 	(g)	Solvency. The fair salable value of Debtor’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; the Debtor is

	 	(h)	Financial Statements Prepared In Accordance with GAAP. Debtor’s audited financial statements for fiscal years 2003 and 2004 delivered to Secured Party in
connection with the Indebtedness have been prepared in accordance with generally accepted accounting principles. Debtor’s cash flow financial statements prepared by Debtor and delivered to Secured Party in connection with the Indebtedness have

Debtor’s business, to the extent that failure to do so would have a material adverse effect on Debtor’s business, and (ii) not allow any Intellectual Property material to Debtor’s business to be abandoned, forfeited or dedicated
to the public other than in the ordinary course of business. Debtor’s obligations under this section shall be subject to Debtor’s good faith determination as to whether and in what manner Debtor should exercise its obligations, including
as to whether and in what manner legal proceedings should be pursued. 

  

	 	(o)	Taxes. All federal, state and local tax returns required to be filed by Debtor have been filed with the appropriate governmental agencies and all taxes due and
payable by Debtor have been timely paid. Debtor will pay when due all taxes, assessments and other liabilities except as contested in good faith and by appropriate proceedings and for which adequate reserves have been established;

  

	 	(p)	No Defaults. To Debtor’s knowledge, no event or condition exists under any material agreement, instrument or document to which Debtor is a party or may be
subject, or by which Debtor or any of its properties are bound, which constitutes a default or an event of default thereunder, or will, with the giving of notice, passage of time, or both, would constitute a default or event of default thereunder;

	 	(s)	 Transactions with Affiliates. Except for any agreements or arrangements that exist as of the date hereof with any Affiliate of Debtor, Debtor
shall not, without the prior written consent of Secured Party, directly or indirectly enter into or permit to exist any material transaction with any Affiliate of Debtor except for transactions

  

 3 

	 	 
that are in the ordinary course of Debtor’s business, upon fair and reasonable terms that are no less favorable to Debtor than would be obtained in an arm’s length transaction with a
nonaffiliated Person. 

  

	 	(t)	Audits. Debtor shall allow Secured Party to audit Debtor’s Collateral at Debtor’s expense upon reasonable prior written notice to Debtor. Such audits

possession of the Collateral; except that Secured Party shall have the right to possess (i) any chattel paper or instrument that constitutes a part of the Collateral, and (ii) any other Collateral in which Secured Party’s security

without the prior written consent of the Secured Party, and the Collateral is now and shall at all times remain personal property except with the Secured Party’s prior written consent. If any of the Collateral is or will be attached to real
estate in such a manner as to become a fixture under applicable state law and if such real estate is encumbered, the Debtor will obtain from the holder of each Lien or encumbrance a written consent and subordination to the security interest hereby
granted, or a written disclaimer of any interest in the Collateral, in a form reasonably acceptable to the Secured Party. 

  

	 	(i)	Distributions. Debtor shall not (i) pay any dividends or make any distributions on its equity securities; (ii) purchase, redeem, retire, defease or

money or lease obligations so as to accelerate the scheduled repayment thereof or (iii) repay any notes to officers, directors or shareholders except as expressly provided for in a duly executed subordination agreement in favor of, and approved
by Secured Party, or except by conversion of such notes to capital stock. 

  

	 	(k)	 Bridge Loans. Debtor shall not incur any indebtedness for borrowed money or lease obligations (collectively, “Bridge Loans”) from any
of its officers, directors or shareholders (collectively, “Bridge Loan Lenders”) unless each of the Bridge

Loan Lenders have executed and delivered subordination agreements in favor of Secured Party, in form satisfactory to Secured Party, which subordinate all of the Bridge Loans to the Indebtedness.

  

	 	(l)	Negative Pledge Regarding Intellectual Property. Debtor shall not sell, transfer, assign, mortgage, pledge, lease, grant a security interest in, or encumber any
of its Intellectual Property, or enter into any agreement, document, instrument or other arrangement (except with or in favor of Secured Party or Horizon) with any entity which directly or indirectly prohibits or has the effect of prohibiting Debtor
from selling, transferring, assigning, mortgaging, pledging, leasing, granting a security interest in or upon, or encumbering any of Debtor’s Intellectual Property; provided, however, that Debtor may grant licenses or leases with respect to
components of Debtor’s Intellectual Property (a) pursuant to or in connection with license agreements, joint ventures and corporate collaborations in the ordinary course of business or (b) as may be customary in the pharmaceutical,
biotechnical or tissue engineering industries.

	 	(a)	Risk of Loss. Debtor shall at all times bear the entire risk of any loss, theft, damage to, or destruction of, any of the Collateral from any cause whatsoever.

  

	 	(b)	Insurance Requirements. Debtor agrees to keep the Collateral insured against loss or damage by fire and extended coverage perils, theft, burglary, and for any or
all Collateral, which are vehicles, for risk of loss by collision, and if requested by Secured Party, against such other risks as Secured Party may reasonably require. The insurance coverage shall be in an amount no less than the full replacement
value of the Collateral, and deductible amounts, insurers and policies shall be reasonably acceptable to Secured Party. Debtor shall deliver to Secured Party policies or certificates of insurance evidencing such coverage. Each policy shall name
Secured Party as a loss payee, shall provide for coverage to Secured Party regardless of the breach by Debtor of any warranty or representation made therein, shall not be subject to co-insurance, and shall provide that coverage may not be canceled
or altered by the insurer except upon at least thirty (30) days’ prior written notice to Secured Party. Debtor appoints Secured Party as its attorney-in-fact to make proof of loss, claim for insurance and adjustments with insurers, and to
receive payment of and execute or endorse all documents, checks or drafts in connection with insurance payments. Secured Party shall not act as Debtor’s attorney-in-fact unless an Event of Default has occurred and is continuing. Proceeds of

	 	(b)	 Acceleration. Upon the occurrence and during the continuance of an Event of Default, the Secured Party, at its option, may declare any or all of
the Indebtedness to be immediately due and payable, without demand or notice to Debtor or any Guarantor (provided that if there is an Event of Default as a result of a bankruptcy or insolvency all Indebtedness shall

  

 11 

	 	 
become immediately due and payable without any action by Secured Party). The accelerated obligations and liabilities shall bear interest (both before and after any judgment) until paid in full at
the Default Rate. 

  

	 	(c)	Rights and Remedies. Secured Party shall have all of the rights and remedies of a Secured Party under the Uniform Commercial Code, and under any other applicable

any instrument which constitutes part of the Collateral to make payment to the Secured Party, (ii) with or without legal process, enter any premises where the Collateral may be and take possession of and remove the Collateral from the premises
or store it on the premises, (iii) sell the Collateral at public or private sale, in whole or in part, and have the right to bid and purchase at said sale, or (iv) lease or otherwise dispose of all or part of the Collateral, applying
proceeds from such disposition to the obligations then in default. If requested by Secured Party, Debtor shall promptly assemble the Collateral and make it available to Secured Party at a place to be designated by Secured Party, which is reasonably
convenient to both parties. Secured Party may also render any or all of the Collateral unusable at the Debtor’s premises and may dispose of such Collateral on such premises without liability for rent or costs. Any notice that Secured Party is
required to give to Debtor under the Uniform Commercial Code of the time and place of any public sale or the time after which any private sale or other intended disposition of the Collateral is to be made shall be deemed to constitute reasonable
notice if such notice is given to the last known address of Debtor at least ten (10) days prior to such action. Upon the occurrence and during the continuation of an Event of Default, Debtor hereby appoints Secured Party as Debtor’s

Stock or Series A-2 Preferred Stock, as the case may be, then held by them. 
  

	 	(4)	Liquidation. 

 (a)
Liquidation Priorities. In the event of an involuntary or voluntary liquidation or dissolution of the corporation legally available for distribution at any time, the holders of shares of Series A-1 Preferred Stock and Series A-2 Preferred
Stock shall be entitled to receive, pari passu, out of the assets of the corporation an amount equal to $1.61683 per share (as appropriately adjusted to reflect stock splits, stock dividends, reorganizations, consolidations and similar
changes hereafter effected) plus an amount in cash equal to all accrued but unpaid dividends thereon (the aggregate of such amount being hereafter referred to as the “Series A Liquidation Preference”) before any payment shall be
made or any assets distributed to the holders of the Common Stock or any other class or series of shares ranking junior to the Series A Preferred Stock upon liquidation or dissolution of the corporation. 
 (b) Deficiencies Upon Liquidation. If upon any involuntary or voluntary liquidation or dissolution of the corporation, the assets
legally available for distribution shall be insufficient to pay the full amount of the Series A Liquidation Preference to all holders of shares of Series A-1 Preferred Stock and Series A-2 Preferred Stock, the holders of such shares of Series A-1
Preferred Stock and Series A-2 Preferred Stock shall share pro rata in any such distribution. 
 (c) Remaining
Assets. After the payment or setting apart for payment to the holders of the Series A Preferred stock of the full preferential amounts so payable to them, the remaining assets of the corporation legally available for distribution to stockholders
shall be distributed among the holders of the Common Stock, the holders of the Series A-1 Preferred stock and the holders of the Series A-2 Preferred Stock pro rata based on the number of shares of Common Stock held by each (assuming
conversion of all such shares of Series A Preferred stock into Common Stock). 
 (d) Deemed Liquidation Event. Unless
voted to be treated otherwise by the Required Series A Holders, each of the following will be treated as a “dissolution.” 
 (i) the acquisition of the corporation by another entity by means of any transaction or series of related transactions, including, without limitation, any stock acquisition, reorganization, merger or
consolidation (but excluding any sale of stock for capital raising purposes) other than transactions in which the holders of the outstanding voting securities of the corporation immediately prior to such transaction continue to retain (either by
such voting securities remaining outstanding or by such voting securities being converted into voting securities of the surviving entity), as a result of shares in the corporation held by such holders prior to such transactions, greater than fifty
percent (50%) of the total voting power represented by voting securities of the corporation or such surviving entity outstanding immediately after such transaction or series of transactions, 
  

 5 

 (ii) the acquisition in any transaction or series of related transactions by
a single person or entity of such number of shares of capital stock of the corporation which results in such person or entity (in each case, together with its affiliates) owning at least a majority of the outstanding voting securities of the
corporation immediately after such acquisition (each event in clauses(i) and (ii), a “Change of Control Transaction”), and 
 (iii) a sale or other conveyance of all or substantially all of the assets of the corporation, by means of a transaction or series of related transactions (each event in clauses (i) through
(iii) above of this subsection are referred to herein as a “Deemed Liquidation Event”). 
 Unless voted by
the Required Series A Holders not to be treated as a dissolution, all consideration payable to the stockholders of the corporation in connection with any Change of Control Transaction, or all consideration payable to the corporation and
distributable to its stockholders, together with all other available assets of the corporation, in connection with any such asset sale, shall be, as applicable, paid by the purchaser to the holders of, or distributed by the corporation in redemption
(out of funds legally available therefor) of, the Series A-1 Preferred Stock, Series A-2 Preferred Stock and Common stock in accordance with the preferences and priorities set forth in Sections B(4)(a)(c) above, with such preferences and
priorities specifically intended to be applicable in any such Change of Control Transaction or asset sale as if such transaction were a dissolution. In furtherance of the foregoing, the corporation shall take such actions as are necessary to give
effect of the provisions of this Section B(4)(d), including without limitation, (A) in the case of a merger or consolidation, causing the definitive agreement relating to such merger or consolidation or provide for a rate at which the
shares of Series A Preferred Stock are converted into or exchanged for cash, new securities or other property so as to give effect to the liquidation preferences and priorities provided for in this Section B(4), or otherwise causing such
shares to be redeemed in a manner that gives effect to the liquidation preferences and priorities provided for in this Section B(4), or (B) in the case of such a stock sale or an asset sale, redeeming the Series A Preferred Stock in a
manner that gives effect to the liquidation preferences and priorities provided for in this Section B(4), except to the extent it is not a Deemed Liquidation Event pursuant to this Section B(4)(d). The corporation shall promptly
provide to the holders of shares of Series A Preferred Stock and Common Stock such information concerning the terms of such merger, consolidation, stock sale or asset sale and the value of the assets of the corporation as may reasonably be requested
by the holders of Series A Preferred Stock. The amount deemed distributed to the holders of Series A Preferred Stock upon any such transaction shall be the cash or the value of the property, rights or securities distributed to such holders by the
corporation or the acquiring person, firm or other entity, as applicable. Any election by the Required Series A Holders pursuant to this Section B(4)(d) shall be made by written notice to the corporation, the other holders of Series A
Preferred Stock and the holders of Common Stock at least ten (10) days prior to the closing of the relevant transaction. Upon the election of such Required Series A Holders hereunder, all holders of Series A Preferred Stock shall be deemed to
have made such election and such election shall bind all holders of the Series A Preferred Stock. In the event that the requirements of this Section B(4)(d) are not complied with, the corporation shall cause such closing to be postponed until
such time as the requirements of this Section B(4)(d) have been complied with, or cancel such transaction, in which event the rights, preferences and privileges of the holders of

  

 6 

 
the Series A Preferred Stock shall revert to and be the same as such rights, preferences and privileges existing immediately prior to the date of the first notice referred to in this Section
B(4)(d). 
 (e) Non-Cash Assets. If any of the assets of the corporation are to be distributed under this Section
B(4), or for any purpose, in a form other than cash, then the board of directors of the corporation shall promptly and reasonably determine in good faith the fair market value of the assets to be distributed to the holders of Series A Preferred
Stock or Common Stock. The corporation shall, upon receipt of such determination, give prompt written notice of the determination to each holder of shares of Series A Preferred Stock or Common Stock. Notwithstanding the foregoing, the fair market
value of any securities shall be valued as follows: 
 (i) Securities not subject to investment letter or other
similar restrictions on free marketability: 
 (A) If traded on a securities exchange or Nasdaq National Market,
the value shall be deemed to be the average of the closing sale prices of the securities on the Nasdaq National Market or such exchange, as applicable, over the thirty (30) calendar day period ending three (3) calendar days prior to the
consummation of a liquidation, dissolution or winding up of the corporation; 
 (B) If actively traded
over-the-counter, the value shall be deemed to be the average of the closing bid or sale prices (whichever is applicable) over the thirty (30) calendar day period ending three (3) calendar days prior to the consummation of a liquidation,
dissolution or winding up of the corporation; or 
 (C) If thee is no active public market, the value shall be
the fair market value thereof, as determined by a majority of the board of directors of the corporation in good faith. 
 (ii) The method of valuation of securities subject to investment letter or other restrictions on free marketability (other than restrictions arising solely by virtue of a stockholder’s status as an affiliate or former affiliate) shall
be to make an appropriate discount from the market value determined as above in (i)(A), (B) or (C) to reflect the approximate fair market value thereof, as determined by the board of directors of the corporation in good faith. 

 

	 	(5)	Redemption of Series A-1 Preferred Stock and Series A-2 Preferred Stock. 

 (a) Subject to the rights of series of preferred stock which may from time to time come into existence, (i) after the receipt by the
corporation of a written request from the holders of not less than the Required Series A Holders that all or some of such holders’ shares be redeemed, at any time after the sixth year anniversary of the date hereof, but within ninety
(90) days of such request (the date ninety (90) days after such request is hereinafter referred to as the “First Redemption Date”), the corporation shall, to the extent it may lawfully do so, redeem one-third of the shares
of Series A Preferred Stock then outstanding, (ii) after the receipt by the

  

 7 

 
corporation of a written request form the Required Series A Holders that all or some of such holders’ shares be redeemed, at any time after the seventh year anniversary of the date hereof,
but within ninety (90) days of such request (the date ninety (90) days after such request is hereinafter referred to as the “Second Redemption Date”), the corporation shall, to the extent it may lawfully do so, redeem
one-half of the shares of Series A Preferred Stock then outstanding, and (iii) after the receipt by the corporation of a written request form the Required Series A Holders that all or some of such holders’ shares be redeemed, at any time
after the eighth year anniversary of the date hereof, but within ninety (90) days of such request (the date ninety (90) days after such request is hereinafter referred to as the “Third Redemption Date”), the corporation
shall, to the extent it may lawfully do so, redeem all of the shares of Series A Preferred Stock then outstanding in each case, by paying in cash therefor a sum equal to the then applicable Series A Liquidation Preference of such share of each of
the Series A-1 Preferred Stock and Series A-2 Preferred Stock (the “Applicable Redemption Price”). Any redemption effected pursuant to this Section B(5)(a) shall be made on a pro rata basis among the holders of the
Series A Preferred Stock in proportion to the number of shares of Series A Preferred Stock then held by such holders. 
 (b)
Subject to the rights of series of preferred stock which may from time to time come into existence, at least fifteen (15) days prior to each of First Redemption Date, Second Redemption Date or Third Redemption Date, as applicable (each of First
Redemption Date, Second Redemption Date and Third Redemption Date shall be referred to as a “Redemption Date”), written notice shall be mailed, first class postage prepaid, to each holder of record (at the close of business on the
business day next preceding the day on which notice is given) of the Series A Preferred Stock to be redeemed, at the address last shown on the records of the corporation for such holder, notifying such holder of the redemption to be effected,
specifying the number of shares to be redeemed from such holder, the Redemption Date, the Applicable Redemption Price, the place at which payment may be obtained and calling upon such holder to surrender to the corporation, in the manner and at the
place designated, his, her or its certificate or certificates representing the shares to be redeemed (the “Redemption Notice”). Except as provided in Section B(5)(c) on or after the Redemption Date, each holder of Series A
Preferred Stock to be redeemed shall surrender to the corporation the certificate or certificates representing such shares, in the manner and at the place designated in the Redemption Notice, and thereupon the Applicable Redemption Price of such
shares shall be payable to the order of the person whose name appears on such certificate or certificates as the owner thereof and each surrendered certificate shall be cancelled. In the event less than all the shares represented by any such
certificate are redeemed, a new certificate shall be issued representing the unredeemed shares. 
 (c) From and after the
Redemption Date, unless there shall have been a default in payment of the Applicable Redemption Price, all rights of the holders of shares of Series A Preferred Stock designated for redemption in the Redemption Notice as holders of Series A
Preferred Stock (except the right to receive the Redemption Price without interest upon surrender of their certificate or certificates) shall cease with respect to such shares, and such shares shall not thereafter be transferred on the books of the
corporation or be deemed to be outstanding for any purpose whatsoever. Subject to the rights of series of preferred stock which may from time to time come into existence, if the funds of the corporation legally available for redemption of shares of
Series A Preferred Stock on any Redemption Date are insufficient to

  

 8 

 
redeem the total number of shares of Series A Preferred Stock to be redeemed on such date, those funds which are legally available will be used to redeem the maximum possible number of such
shares of Series A-1 Preferred Stock and Series A-2 Preferred Stock ratably among the holders of such shares to be redeemed based upon their holdings of Series A-1 Preferred Stock and Series A-2 Preferred Stock, taken together as a single class. The
shares of Series A Preferred Stock not redeemed shall remain outstanding and entitled to all the rights and preferences provided herein. Subject to the rights of series of preferred stock which may from time to time come into existence, at any time
thereafter when additional funds of the corporation are legally available for all redemption of shares of Series A Preferred Stock, such funds will immediately be used to redeem the balance of the shares which the corporation has become obliged to
redeem on any Redemption Date but which it has not redeemed and no other payment to any other class or series of capital stock shall be made until the balance of the shares which the corporation has become obliged to redeem has been so redeemed.

  

	 	(6)	Conversion of Series A-1 Preferred Stock and Series A-2 Preferred Stock. 

 (a) Mandatory Conversion of Series A Preferred Stock. The Series A Preferred Stock shall automatically be converted into shares of
Common Stock of the corporation, without any act by the corporation or the holders of the Series A Preferred Stock, upon the earlier of: 
 (i) concurrently with the closing of the first public offering by the corporation of shares of Common Stock of the corporation registered under the Securities Act of 1933, as amended, in which
(x) the aggregate public offering price of the securities sold for cash by the corporation is not less than $40,000,000 and (y) the per share price paid for such shares shall be at least $4.85 (appropriately adjusted for any combinations,
consolidations, stock splits, or stock distributions or stock dividends with respect to such shares) (“Qualified Public Offering”); or 
 (ii) the date upon which the affirmative vote or written consent in favor of such conversion is given by the Required Series A Holders. 
 Each holder of a share of Series A Preferred Stock so converted shall be entitled to receive the full number of shares of Common Stock into
which such share of Series A Preferred Stock held by such holder could be converted if such holder had exercised its optional conversion right at the time of the closing of such public offering or the giving of such vote or consent, as applicable.
Upon such conversion, each holder of a share of Series A Preferred Stock shall immediately surrender such share in exchange for appropriate stock certificates representing a share or shares of Common Stock of the corporation. 
 (b) Optional Conversion of Series A Preferred Stock. At any time from time to time, at the option of any holder thereof, the Series
A-1 Preferred Stock and Series A-2 Preferred Stock shall be convertible, at the office of the corporation (or at such other office or offices, if any, as the board of directors may designate), into fully paid and nonassessable shares of Common Stock
of the corporation, at the Applicable Series A-1 Conversion Price or the Applicable Series A-2 Conversion Price, as applicable (as determined in accordance with the provisions of Section B(6)(c) below), in effect at the time of conversion. To
convert shares of

  

 9 

 
Series A-1 Preferred Stock or Series A-2 Preferred Stock into shares of Common Stock of the corporation, the holder thereof shall surrender at the principal office of the corporation the
certificate or certificates therefor, duly endorsed to the corporation or in blank, and give written notice to the corporation at such office that such holder elects to convert such shares. Shares of Series A-1 Preferred Stock or Series A-2
Preferred Stock, as the case may be, shall be deemed to have been converted immediately prior to the close of business on the day of the surrender of such shares for conversion as herein provided, and the person entitled to receive the shares of
Common Stock of the corporation issuable upon such conversion shall be treated for all purposes as the record holder of such share of Common Stock at such time. As promptly as practicable on or after the conversion date, the corporation shall issue
and deliver or cause to be issued and delivered at such office a certificate or certificates for the number of shares of Common Stock of the corporation issuable upon such conversion. 
 (c) Conversion Price and Adjustments. The number of shares of Common Stock issuable upon conversion of each share of the Series A-1
Preferred Stock, whether optional or mandatory conversion, shall be equal to $1.61683 plus an amount equal to all accrued but unpaid dividends thereon (as appropriately adjusted to reflect stock splits, stock dividends, reorganizations,
consolidations and similar changes hereafter effected with respect to the Series A-1 Preferred Stock) divided by the Applicable Series A-1 Conversion Price (as defined below) then in effect for shares of Series A-1 Preferred Stock. The number of
shares of Common Stock issuable upon conversion of each share of Series A-2 Preferred Stock, whether optional or mandatory conversion, shall be equal to $1.61683 plus an amount equal to all accrued but unpaid dividends thereon (subject to adjustment
in the event of any stock dividend, stock split, combination, reorganization, recapitalization, reclassification, or other similar event, in each case involving only the Series A-2 Preferred Stock) divided by the Applicable Series A-2 Conversion
Price then in effect for shares of Series A-2 Preferred Stock. The Applicable Series A-1 Conversion Price for shares of Series A-1 Preferred Stock shall initially be $1.61683 and the Applicable Series A-2 Conversion Price (collectively with the
Applicable Series A-1 Conversion Price, the “Applicable Conversion Price”) for shares of Series A-2 Preferred Stock shall initially be $1.61683, in each case subject to adjustment from time to time as hereinafter provided (it being
understood that the Series A-2 Conversion Price shall not be subject to adjustment as provided in clause (i) below of this Section B(6)(c)): 
 (i) Except for (1) the issuance of options to purchase and/or the sale of up to, in the aggregate, 4,536,077 shares of Common Stock (subject to adjustment in the event of any stock dividend, stock
split, combination, reorganization, recapitalization, reclassification, or other similar event, in each case involving only the Common Stock) granted or sold to employees, consultants or directors of the corporation pursuant to any equity
compensation plans approved by the board of directors of the corporation, including the issuance of Common Stock upon exercise of such options, (2) the issuance of shares of Common Stock upon conversion of the Preferred Stock, (3) shares
of Common Stock issued or issuable in connection with stock splits, divisions or dividend distributions, (4) shares of Common Stock issued or issuable to lending or leasing institutions in connection with the corporation’s debt, equipment
leasing or other non-equity financing approved by the board of directors (including at least a majority of the Preferred Directors), (5) shares of Common Stock issued or issuable upon exercise or conversion of any securities outstanding on the
Purchase Date (as defined below),

  

 10 

 
(6) shares of Common Stock issued or issuable in connection with a strategic partnering, joint venture, or licensing arrangement, or consulting, executive recruitment, real estate or vendor
transaction first approved by the board of directors of the corporation (including at least a majority of the Preferred Directors), provided that the primary purpose of such transaction is not the raising of equity capital, (7) shares of
Common Stock issued or issuable in connection with a bona fide business acquisition by the corporation, whether by merger, consolidation, sale of assets, sale or exchange of stock, whereby the corporation owns not less than a majority of the voting
power of the surviving corporation, in each case, approved by the board of directors (including at least a majority of the Preferred Directors), (8) the issuance of shares of Common Stock pursuant to a Qualified Public Offering, (9) any
right, option or warrant to subscribe for, purchase or otherwise acquire any security described in the foregoing clauses (4) – (7) of this Section B(6)(c)(i), (10) any right, option or warrant exercisable for or
convertible into any security that is exercisable for or convertible into any security described in clauses (4) – (7) of this Section B(6)(c)(i), and (11) such other issuances of shares of Common Stock of the corporation
as to which the provisions of this Section B(6)(c) may be waived by the Required Series A Holders, if the corporation shall issue, after the date upon which any shares of Series A-1 Preferred Stock were first issued (the “Purchase
Date”), any shares of Common Stock without consideration or for a consideration per share less than the Applicable Series A-1 Conversion Price in effect for the Series A-1 Preferred Stock immediately prior to the issuance of such shares of
Common Stock, the Applicable Series A-1 Conversion Price in effect for the Series A-1 Preferred Stock immediately prior to each such issuance shall forthwith be adjusted to a price determined by multiplying such Applicable Series A-1
Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (including, without limitation, the number of shares of Common Stock issuable upon the conversion of
all of the outstanding Preferred Stock and other Convertible Securities and assuming the exercise of all outstanding options, warrants or other rights to purchase Common Stock or other securities convertible into Common Stock) plus the number of
shares of Common Stock that the aggregate consideration received by the corporation for such issuance would purchase at such Applicable Series A-1 Conversion Price; and the denominator of which shall be the number of shares of Common Stock
outstanding immediately prior to such issuance (including, without limitation, the number of shares of Common Stock issuable upon the conversion of all of the outstanding Preferred Stock and other Convertible Securities and assuming the exercise of
all outstanding options, warrants or other rights to purchase Common Stock or other securities convertible into Common Stock) plus the number of shares of Common Stock thus issued or sold. 
 For the purposes of this Section B(6)(c)(i) the following clauses (1) to (4), inclusive, shall also be applicable: 

(1) In case at any time the corporation shall grant (1) any rights subscribe for or to purchase, or any options for
the purchase of, Common Stock or (2) any obligations or any shares of stock of the corporation which are convertible into, or exchangeable for, Common Stock (any of such obligations or shares of stock being hereinafter referred

  

 11 

 
to as “Convertible Securities”) whether or not such rights or options or the right to convert or exchange any such Convertible Securities are immediately exercisable, and the
price per share for which Common Stock is issuable upon the exercise of such rights or options or upon conversion or exchange of such Convertible Securities (determined by dividing (x) the total amount, if any, received or receivable by the
corporation as consideration for the granting of such rights or options, plus the minimum aggregate amount of additional consideration payable to the corporation upon the exercise of such rights or options, plus, in the case of such rights or
options which relate to Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable upon the issue of such Convertible Securities and upon the conversion or exchange thereof by (y) the total maximum number
of shares of Common Stock issuable upon the exercise of such rights or options or upon the conversion or exchange of all such Convertible Securities issuable upon the exercise of such rights or options) shall be less than the Applicable A-1
Conversion Price with respect to the Series A-1 Preferred Stock in effect immediately prior to the time of the granting of such rights options, then the total maximum number of shares of Common Stock issuable upon the exercise of such rights or
options or upon conversion or exchange of the total minimum amount of such Convertible Securities issuable upon the exercise of such rights options shall (as of the date of granting of such rights or options) be deemed to have been issued for such
price per share. Except as provided in Section B(6)(c)(ii) below, no further adjustments of the Applicable Conversion Price with respect to the Series A-1 Preferred Stock shall be made upon the actual issue of such Common Stock or of such
Convertible Securities upon exercise of such rights or options or upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities. 
 (2) In case the corporation shall issue or sell (whether directly or by assumption in a merger or otherwise) any Convertible
Securities, whether or not the rights to exchange or convert thereunder are immediately exercisable, and the price per share for which Common Stock is issuable upon such conversion or exchange (determined by dividing (x) the total amount of
consideration received or receivable by the corporation for the issuance or sale of such Convertible Securities, plus the minimum aggregate amount of additional consideration, if any, payable to the corporation upon the conversion or exchange
thereof, by (y) the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities) shall be less than the Applicable Series A-1 Conversion Price with respect to the Series A-1
Preferred Stock in effect immediately prior to the time of such issue or sale, then the total maximum number of shares of Common Stock issuable upon conversion or exchange of all such Convertible Securities shall (as of the date of the issue or sale
of such Convertible Securities) be deemed to be outstanding and to have been issued for such price per share,

  

 12 

 
provided that (x) except as provided in Section B(6)(c)(ii) below, no further adjustments of the Applicable Conversion Price with respect to the Series A-1 Preferred Stock
shall be made upon the actual issue of such Common Stock upon conversion or exchange of such Convertible Securities, and (y) if any such issue or sale of such Convertible Securities is made upon exercise of any rights to subscribe for or to
purchase or any option to purchase any such Convertible Securities for which adjustments of the Applicable Series A-1 Conversion Price with respect to the Series A-1 preferred Stock have been or are to be made pursuant to other provisions of this
clause (2), no further adjustment of such applicable Conversion Price shall be made by reason of such issue or sale. 
 (3) In case any shares of Common Stock or Convertible Securities or any rights or options to purchase any such Common Stock or Convertible Securities shall be issued or sold for cash, the consideration received therefor shall be deemed to
be the amount received by the corporation therefor, without deducting therefrom any expenses incurred or any underwriting commissions, discounts or concessions paid or allowed by the corporation in connection therewith. In case any shares of Common
Stock or Convertible Securities or any rights or options to purchase any such Common Stock or Convertible Securities shall be issued or sold for a consideration other than cash, the amount of the consideration other than cash received by the
corporation shall be deemed to be the fair value of such consideration as determined by the board of directors of the corporation, without deducting therefrom any expenses incurred or any underwriting commissions, discounts or concessions paid or
allowed by the corporation in connection therewith. In case any shares of Common Stock or Convertible Securities or any rights or options to purchase such Common Stock at Convertible Securities shall be issued in connection with any merger or
consolidation in which the corporation is the surviving corporation, the amount of consideration therefor shall be deemed to be the fair value as determined by the board of directors of the corporation of such portion of the assets and business of
the nonsurviving corporation or corporations as such board shall determine to be attributable to such Common Stock, Convertible Securities, rights or options, as the case may be. 
 (4) If (x) the purchase price provided for in any right or option referred to in clause (1) of this Section
B(6)(c)(i), or (y) the additional consideration, if any, payable upon the conversion or exchange of Convertible Securities referred to in clause (1) or clause (2) of this Section B(6)(c)(i), or (z) the rate at which
any Convertible Securities referred to in clause (1) or clause (2) of this Section B(6)(c)(i) are convertible into or exchangeable for Common Stock, shall change at any time (other than under or by reasons of provisions designed to
protect against dilution), the Applicable Series A-1 Conversion Price then in effect hereunder with respect to the Series A-1 Preferred Stock shall

  

 13 

 
forthwith be increased or decreased to such conversion price as would have obtained had the adjustments made upon the issuance of such rights, options or Convertible Securities been made upon the
basis of (a) the issuance of the number of shares of Common Stock theretofore actually delivered upon the exercise of such options or rights or upon the conversion or exchange of such Convertible Securities, and the total consideration received
therefor, and (b) the issuance at the time of such change of any such options, rights, or Convertible Securities then still outstanding for the consideration, if any, received by the corporation therefor and to be received on the basis of such
changed price; and on the expiration of any such option or right or the termination of any such right to convert or exchange such Convertible Securities, the Applicable Series A-1 Conversion Price then in effect hereunder with respect to the Series
A-1 Preferred Stock shall forthwith be increased to such conversion price as would have obtained had the adjustments made upon the issuance of such rights or options or Convertible Securities been made upon the basis of the issuance of the shares of
Common Stock theretofore actually delivered (and the total consideration received therefore) upon the exercise of such rights or option or upon the conversion or exchange of such Convertible Securities. If the purchase price provided for in any
right or option referred to in clause (1) of this Section B(6)(c)(i), or the rate at which any Convertible Securities referred to in clause (1) of this Section B(6)(c)(i) are convertible into or exchangeable for Common Stock,
shall decrease at any time under or by reason of provisions with respect thereto designed to protect against dilution, then in case of the delivery of Common Stock upon the exercise of any such right or option or upon conversion or exchange of any
such Convertible Security, the Applicable Series A-1 Conversion Price then in effect hereunder with respect to the Series A-1 Preferred Stock shall forthwith be decreased to such conversion price as would have obtained had the adjustments made upon
the issuance of such right, option or Convertible Security been made upon the basis of the issuance of (and the total consideration received for) the shares of Common Stock delivered as aforesaid. 
 (ii) In case the corporation shall at any time subdivide its outstanding shares of Common Stock into a greater number of
shares, the Applicable Conversion Price for the Series A-1 Preferred Stock and the Series A-2 Preferred Stock in effect immediately prior to such subdivision shall be proportionately reduced, and conversely, in case the outstanding shares of Common
Stock of the corporation shall be combined into a smaller number of shares, the Applicable Conversion Price for the Series A-1 Preferred Stock and the Series A-2 Preferred Stock in effect immediately prior to such combination shall be
proportionately increased. 
 (d) Reorganization or Reclassification. If any capital reorganization or reclassification
of the capital stock of the corporation shall be effected in such a way that holders of Common Stock shall be entitled to received stock, securities or assets with respect to or in

  

 14 

 
exchange for Common Stock, then, as a condition of such reorganization or reclassification, lawful and adequate provisions shall be made whereby each holder of Series A-1 Preferred Stock and
Series A-2 Preferred Stock shall thereupon have the right to receive, upon the basis and upon the terms and conditions specified herein and in lieu of Common Stock immediately therefore receivable upon the conversion of shares of the shares of
Series A-1 Preferred Stock and Series A-2 Preferred Stock, as applicable, such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the
number of shares of such Common Stock immediately theretofore receivable upon such conversion had such reorganization or reclassification not taken place, and in any such case appropriate provisions shall be made with respect to the rights and
interests of such holder to the end that the provisions hereof (including without limitation provisions for adjustments of the Applicable Conversion Price) shall thereafter be applicable, as nearly as may be, in relation to any shares of stock,
securities or assets thereafter deliverable upon the exercise of such conversion rights. 
 (e) Corrective Actions. If
any event occurs as to which in the opinion of the board of directors of the corporation the other provisions of Section B(6) are not strictly applicable or if strictly applicable would not fairly protect the rights of the holders of the
Series A Preferred Stock in accordance with the essential intent and principles of such provisions, then the board of directors shall make an adjustment in the application of such provisions, in accordance with such essential intent and principles,
so as to protect such rights as aforesaid. 
 (f) Notice of Conversion Price Adjustment. In each case of an adjustment of
the Applicable Conversion Price with respect to the Series A Preferred Stock, the corporation shall give written notice thereof, by first-class, mail, postage prepaid, addressed to the registered holders of the Series A-1 Preferred Stock and the
Series A-2 Preferred Stock, as the case may be, at the addresses of such holders as shown on the books of the corporation, which notice shall state the Applicable Series A-1 Conversion Price and the Series A-2 Conversion Price resulting from such
adjustment and the increase or decrease, if any, in the number of shares receivable at such price upon the conversion of the Series A-1 Preferred Stock and the Series A-2 Preferred Stock, as the case may be, setting forth in reasonable detail the
method of calculation and the facts upon which such calculation is based. 
 (g) Fractional Shares. No fractional shares
of Common Stock shall be issued upon conversion, but, instead of any fraction of a share which would otherwise be issuable, the corporation shall pay a cash adjustment in respect of such fraction in an amount equal to the same fraction of the market
price per share of Common Stock as of the close of business on the day of conversion. “Market price” shall mean if the Common Stock is traded on a securities exchange or on the Nasdaq National Market, the closing price of the Common
Stock on such exchange or the Nasdaq National Market, or, if the Common Stock is otherwise traded in the over-the-counter market, the closing bid price, in each case averaged over a period of 20 consecutive business days prior to the date as of
which “market price” is being determined. If at any time the Common Stock is not traded on an exchange or the Nasdaq National Market, or otherwise traded in tire over-the-counter market, the “market price” shall be deemed to be
the higher of (x) the book value thereof as determined by any firm of independent public accounts of recognized standing selected by the board of directors of the corporation as of the last day of any month ending within 60 days preceding the
date as of which the determination is to be made, or

  

 15 

 
(y) the fair value thereof determined in good faith by the board of directors of the corporation as of the date which is within 15 days of the date as of the which the determination is to be
made. 
 (h) No Impairment. The corporation will not, by amendment of its certificate of incorporation or through any
reorganization, recapitalization, 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 to be observed or performed
hereunder by the corporation, but will at all times in good faith assist in the carrying out of all the provisions of this Section B(6) and in the taking of all such action as may be necessary or appropriate in order to protect the holders of
Series A Preferred Stock against impairment. 
 (i) Reservation of Stock Issuable Upon Conversion. The corporation shall
at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of effecting the conversion of any outstanding shares of Series A-1 Preferred Stock and Series A-2 Preferred Stock; and if at
any time the number of authorized but unissued shires of Common Stock shall not be sufficient to effect the exercise of all such Series A Preferred Stock, the corporation will take such corporate action as may, in the opinion of its counsel, be
necessary to increase its authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such purposes, including, without limitation, using its best efforts to obtain the requisite stockholder approval of away
necessary amendment to the corporation’s certificate of incorporation. 
 (j) Pay to Play Provision. 
 (i) If from time to time any holder of Series A-1 Preferred Stock is entitled to exercise a right of first offer granted pursuant to
Section 2 of the Investors Rights Agreement (the “Right of First Offer”) with respect to any subsequent round of equity financing of the corporation (the “Equity Financing”) effected after the Purchase Date and
the corporation has fully complied in all respects with its contractual obligations pursuant to such Right of First Offer, if such holder (referred to herein as a “Non-Participating Holder”) does not exercise such holder’s
right of First Offer to acquire its pro rata share (equal to the ratio of the number of shares of Common Stock and Series A-1 Preferred Stock at the time held by such holder, on an as converted to Common Stock basis, to the number of shares
of the corporation’s capital stock ten outstanding, on an as converted to Common Stock basis), of the Allocated Offered Securities (as hereinafter defined) offered to the holders of the Series A-1 Preferred Stock in such Equity Financing (a
“Mandatory Offering”), a portion of the shares of Series A-1 Preferred Stock held by such Non-Participating Holder as is equal to the total number of shares of Series A-1 Preferred Stock held by such Non-participating Holder
multiplied by fraction (a) the numerator of which shall be (i) the full pro rata share of the Allocated Offered Securities which such Non-Participating Holder multiplied by a fraction (a) the numerator of which shall be
(i) the full pro rata share of the Allocated Offered Securities which such Non-participating Holder was entitled to purchase minus (ii) the number of shares of Allocated Offered

  

 16 

 
Securities actually purchased by such Non-Participating Holder and (b) the denominator of which shall be the full pro rata share of the Allocated Offered Securities which such
Non-Participating Holder was entitled to purchase, shall automatically be converted into an equal number of shares of Series A-2 Preferred Stock. If any shares of Series A-1 Preferred Stock are converted at a time when there are any accrued by
unpaid dividends and other amounts due on or in respect of such shares, (A) the corporation shall not be required or obligated to pay any such unpaid dividends and other amounts in connection with such conversion but (B) each share of
Series A-2 Preferred Stock issued in connection with the Special Mandatory Conversion (as defined below) of each such share of Series A-1 Preferred Stock, as of the date of issuance thereof, shall be entitled to accrued and unpaid dividends in the
amount equal to the dividends accrued and unpaid, as of the date of the Special Mandatory Conversion, in respect of each such underlying share of Series A-1 Preferred Stock so converted (which dividends will be payable as provided in Sections
B(3), (4), (5) and/or (6)(c)). No share of Series A-2 Preferred Stock shall be issued, except as set forth in this Section B(6)(j) upon conversion of shares of Series A-1 Preferred Stock. 
 (ii) An Equity Financing shall not be deemed to be a Mandatory Offering in the event that (A) the board of directors of the corporation
including the affirmative vote of at least a majority of the Preferred Directors and (B) the Required Series A Holders have both specifically approved that such Equity Financing shall not be subject to the terms of this Section B(6)(j).

 Each such conversion under this Section B(6)(j) shall be referred to herein as a “Special Mandatory
Conversion.” 
 For purposes of determining whether any holder of Series A-1 Preferred Stock is a Non-Participating
Holder, the acquisition of Allocated Offered Securities by such holder and each of its affiliates shall be aggregated so that if such holder and each of its affiliates collectively acquire an amount of Allocated Offered Securities equal to or
greater than their collectively pro rata share of the Allocated Offered Securities, neither such holder nor any of its affiliates shall be deemed a Non-Participating Holder. 
 For purposes of this Section B(6)(i), “Allocated Offered Securities” shall mean that portion of the equity securities being issued
in such Equity Financing that are allocated by the board of directors of the corporation, including the affirmative vote of a majority of the Preferred Directors, for purchase by the holders of the Series A-1 Preferred Stock as a group. 

(iii) All Non-Participating Holders shall be given written notice of the Special Mandatory Conversion and the place designated for
mandatory conversion of all or such portion, as the case may be, of their shares of Series A-1 Preferred Stock pursuant to this Section B(6)(j). Such notice shall be sent by first class or registered mail postage prepaid, to each
Non-Participating

  

 17 

 
Holder, at such holder’s address last shown on the records of the transfer agent for the Series A-1 Preferred Stock (or the records of the corporation, if it serves as its own transfer
agent). Upon receipt of such notice, each Non-Participating Holder shall surrender his, her or its certificate or certificates for such shares of Series A-1 Preferred Stock so converted to the corporation at the place designated in such notice, and
shall thereafter receive certificates for the number of shares of Series A-2 Preferred Stock to which such holder is entitled pursuant to this Section B(6)(j) and certificates for the balance of any Series A-1 Preferred Stock not so
converted. On the effective date of the Special Mandatory Conversion, all rights with respect to the Series A-1 Preferred Stock so converted will terminate, except only the rights of the holders thereof, upon surrender of their certificate or
certificates therefor, to receive certificates for the number of shares of Series A-2 Preferred Stock into which such Series A-1 Preferred Stock has been converted. If so required by the corporation, certificates surrendered for conversion shall be
endorsed or accompanied by written instrument tor instruments of transfer, in form satisfactory to the corporation, duly executed by the registered holder or by his, her or its attorney duly authorized in writing. As soon as practicable after the
effective date of the Special Mandatory Conversion and the surrender of the certificate or certificates for Series A-1 Preferred Stock, the corporation shall cause to be issued and delivered to such holder, or on his, her or its written order, a
certificate or certificates for the number of full shares of Series A-2 Preferred Stock issuable on such conversion in accordance with the provisions hereof and a certificate or certificates for the number of full shares of Series A-1 Preferred
Stock not so converted. All certificates evidencing shares of Series A-1 Preferred Stock which are required to be surrendered for conversion in accordance with the provisions hereof shall, from and after the effective date of the Special Mandatory
Conversion, be deemed to have been retired and cancelled and the shares of Series A-1 Preferred Stock represented thereby converted into Series A-2 Preferred Stock for all purposes, notwithstanding the failure of the holder or holders thereof to
surrender such certificates on or prior to such date. Such converted Series A-1 Preferred Stock may not be reissued, and the corporation may thereafter take such appropriate action (without the need for stockholder action) as may be necessary to
reduce the authorized number of shares of Series A-1 Preferred Stock accordingly.

to indemnify and hold harmless, to the extent permitted by applicable law as it presently exists or may hereafter be amended, any employee or agent of the corporation who was or is made or is threatened to be made a party or is otherwise involved in

a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or non-profit entity shall be reduced by any amount such person may collect as indemnification from such other corporation, partnership,
joint venture, trust, enterprise or non-profit enterprise. 
 8. Amendment or Repeal. Any repeal or modification of the
foregoing provisions of this Article XI shall not adversely affect any right or protection hereunder of any person in respect of any act or omission occurring prior to the time of such repeal or modification.
