	$                    	  	May 3, 2012

 1. Principal. Regado Biosciences, Inc., a Delaware corporation (the “Company”),
for value received, hereby promises to pay to the order of [            ] (“Holder”), or its assigns, in lawful money of the United States of America at the address for
notices to Holder set forth below, the principal amount of [            ] together with interest as set forth below (this “Note”). 

This Note is one of a series of Notes (the “Notes”) of like tenor which shall not exceed an aggregate principal amount
of Thirteen Million Five Hundred Sixty-One Thousand and Eighty Dollars and 00/100 ($13,561,080) issued by the Company to certain holders pursuant to the terms of the Purchase Agreement (as defined below). 

2. Interest and Maturity. The Company promises to pay interest on the unpaid principal amount from the date hereof until such
principal amount is paid in full at the rate of eight percent (8%) per annum; provided, however, that upon the occurrence of and during the continuance of an Event of Default, interest will accrue at the rate of fifteen percent (15%) per
annum. Interest from the date hereof 

 
shall be computed on the basis of a 360-day year of twelve 30-day months, and shall accrue monthly and at the end of each 12-month anniversary of the date hereof, be added to principal. Unless
converted or prepaid earlier as set forth below, all unpaid principal and unpaid accrued interest on this Note shall be due and payable on the earlier of (i) subject to the provisions of the Subordination Agreement (as defined herein) and the
occurrence of the “Subordination Termination Date” (under and as defined in the Subordination Agreement), a Change of Control (as defined herein) and (ii) November 30, 2014 (the “Maturity Date”). This Note is
entered into pursuant to the terms of that certain Convertible Note Purchase Agreement among the Company, the Holder and the Purchasers listed on Exhibit A thereto, dated as of May 3, 2012 (the “Purchase Agreement”) and
is subject to its terms. In the event of any conflict between this Note and the Purchase Agreement, the terms of the Purchase Agreement will control. 
 3. Prepayment. All unpaid principal and unpaid accrued interest of this Note may be prepaid without penalty, in whole or in part, only with the written consent of the holders of Bridge Notes (as
defined below) representing a majority of the aggregate principal amount represented by the Bridge Notes. Any prepayment of this Note will be credited first against accrued interest, then principal. Upon payment in full of the amount of all
principal and interest payable hereunder, this Note shall be surrendered to the Company for cancellation. 
 4. Conversion;
Liquidation Premium. 
 4.1 All unpaid principal on this Note and all unpaid accrued interest shall be
converted automatically into the type, kind and character of securities (the “Securities”) issued in the Company’s next Qualified Equity Financing (as defined below) consummated on or before the Maturity Date, with the same
rights, preferences and privileges as are received by other investors, and such Securities shall be issued pursuant to and governed by the same agreements relating to the issuance of the Securities in the Qualified Equity Financing, which agreements
Holder will evidence its consent to by execution of appropriate documentation. Upon such conversion, the Holder shall receive the number of Securities calculated by dividing the amount of principal and accrued interest due under this Note by the
price per share at which the Company sells and issues such Securities pursuant to the Qualified Equity Financing. The Company shall not issue fractional shares upon any conversion of this Note. For purposes of this Note, an “Qualified Equity
Financing” shall mean the Company’s sale of equity securities in one transaction or a series of related transactions to venture capital, institutional or private investors in which at least Twenty Million and No/100 Dollars
($20,000,000.00) in gross cash proceeds is received by the Company (excluding conversion of Notes issued pursuant to the Purchase Agreement). 
 4.2 If a Qualified Equity Financing does not occur on or prior to the Maturity Date then, at the election of the Holder, the Note shall be convertible on and after the Maturity Date into that number of
shares of the Company’s Series D Preferred Stock, par value $0.001 per share (“Series D Preferred Stock”), as is equal to the amount of outstanding principal and accrued interest on this Note on the date of such conversion
divided by the Series D Conversion Price (as defined in the Company’s Certificate of Incorporation) then in effect for the Series D Preferred Stock (the “Series D Conversion Price”). 

4.3 Upon conversion of this Note, the applicable amount of outstanding principal and accrued interest of the Note shall be
converted without any further action by the Holder and whether or not the Note is surrendered to the Company or its transfer agent. The Company shall not be obligated to issue certificates evidencing the shares of the securities issuable upon such
conversion unless such Note is either delivered to the Company or its transfer agent, or the holder notifies the Company or its transfer agent that such Note has been lost, stolen or destroyed and

  
 -2-

 
executes an agreement satisfactory to the Company to indemnify it from any loss incurred by it in connection with such Note. The Company shall, as soon as practicable after such delivery, or such
agreement and indemnification, issue and deliver at such office to such holder of such Note, a certificate or certificates for the securities to which the holder shall be entitled. For a conversion pursuant to Section 4.1, such conversion shall
be deemed to have been made concurrently with the close of the Qualified Equity Financing. For a conversion pursuant to Section 4.4, such conversion shall be deemed to have been made immediately prior to the Change in Control (as defined
below). The person or persons entitled to receive securities issuable upon such conversion shall be treated for all purposes as the record holder or holders of such securities on such date. 

4.4 The Holder may elect, in its sole discretion, upon a Change in Control (as defined below) occurring prior to payment
in full of the original principal amount of this Note and any accrued but unpaid interest thereon or the conversion of the Note pursuant to an Qualified Equity Financing, to (i) convert all unpaid principal on this Note and all accrued but
unpaid interest into shares of the Series D Preferred Stock equal to the amount of the outstanding principal and accrued interest divided by a number equal to half the value of the Series D Conversion Price then in effect for the Series D Preferred
Stock or (ii) subject to the provisions of the Subordination Agreement (as defined herein) and the occurrence of the “Subordination Termination Date” (under and as defined in the Subordination Agreement), demand payment in full of the
Note, in which event the Company shall pay to the Holder an amount equal to twice the sum of (x) unpaid principal on the Note and (y) all accrued but unpaid interest, as of the date immediately following the “Subordination Termination
Date” (as defined in the Subordination Agreement). 
 For the purposes of this Note, the term
“Change in Control” shall mean (i) the reorganization, consolidation or merger of the Company in which the holders of the Company’s outstanding voting securities pre-closing of that event do not retain voting securities
representing a majority of the voting power of the surviving entity (ii) the sale, transfer or exclusive license of all or substantially all of the assets of the Company, or (iii) the sale of equity by the existing holders of capital stock
of the Company the result of which is that more than fifty percent (50%) of the Company’s outstanding voting securities immediately following such transaction are owned by persons or entities who were not equity holders of the Company
immediately prior to any such transaction. 
 5. Attorney’s Fees. If the indebtedness represented by this Note or
any part thereof is collected in bankruptcy, receivership or other judicial proceedings or if this Note is placed in the hands of attorneys for collection after default, the Company agrees to pay, in addition to the principal and interest payable
hereunder, reasonable attorneys’ fees and costs incurred by Holder. 
 6. Notices. Any notice, other communication
or payment required or permitted hereunder shall be given in writing and shall be deemed effectively given as provided in the Purchase Agreement. 
 7. Defaults and Remedies. 
 7.1 Events of Default.
An “Event of Default” shall occur hereunder if: 
 (i) the Company shall default in the payment
of the principal of this Note, when and as the same shall become due and payable; or 

  
 -3-

 (ii) the Company shall default in the payment of any interest on this Note,
when and as the same shall become due and payable; or 
 (iii) the Company shall default in the due observance or
performance of any covenant, representation, warranty, condition or agreement on the part of the Company to be observed or performed pursuant to the terms hereof or pursuant to the terms of the Purchase Agreement or this Note, and such default is
not remedied or waived within the time periods permitted therein, or if no cure period is provided therein, within thirty (30) days after the Company receives written notice of such default; or 

(iv) any representation, warranty, certification or statement made by or on behalf of the Company in the Purchase
Agreement shall have been incorrect in any material respect when made; or 
 (v) if the Company shall commence
any proceeding in bankruptcy or for dissolution, liquidation, winding-up, composition or other relief under state or federal bankruptcy laws; or 
 (vi) if such proceedings are commenced against the Company, or a receiver or trustee is appointed for the Company or a substantial part of its property, and such proceeding or appointment is not dismissed
or discharged within sixty (60) days after its commencement. 
 7.2 Acceleration. If an Event of
Default occurs under Section 7.1(vi) or (vii), then the outstanding principal of and interest on this Note shall automatically become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which are
expressly waived. If any other Event of Default occurs and is continuing, the Holder, by written notice to the Company, may declare the principal of and accrued interest on this Note to be due and payable immediately. Upon any such declaration of
acceleration, such principal and interest shall become immediately due and payable and the Holder shall be entitled to exercise all of its rights and remedies hereunder and under the Purchase Agreement whether at law or in equity. The failure of the
Holder to declare the Note due and payable shall not be a waiver of its right to do so, and the Holder shall retain the right to declare the Note due and payable unless it shall execute a written waiver. 

8. No Rights as a Stockholder. This Note does not by itself entitle the Holder to any voting rights or other rights as a
stockholder of the Company. In the absence of conversion of this Note, no provisions of this Note, and no enumeration herein of the rights or privileges of the Holder, shall cause the Holder to be a stockholder of the Company for any purpose.

 9. No Dilution or Impairment. The Company will not, by amendment of its Certificate of Incorporation or Bylaws 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, but will at all
times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the holder of this Note against dilution or other impairment. 

10. Waiver of Notice of Presentment. The Company hereby waives presentment, demand for performance, notice of non-performance,
protest, notice of protest and notice of dishonor. No delay on the part of Holder in exercising any right hereunder shall operate as a waiver of such right or any other right. 

  
 -4-

 11. Non-Waiver. The failure of the Holder to enforce or exercise any right or remedy
provided in this Note or at law or in equity upon any default or breach shall not be construed as waiving the rights to enforce or exercise such or any other right or remedy at any later date. No exercise of the rights and powers granted in or held
pursuant to this Note by the Holder, and no delays or omissions in the exercise of such rights and powers shall be held to exhaust the same or be construed as a waiver thereof, and every such right and power may be exercised at any time and from
time to time. 
 12. Subordination. The Holder hereby agrees that this Note and any balance hereunder shall be
subordinated in right of payment to any amounts due and owning by the Company pursuant to that certain Loan and Security Agreement, dated as of May 25, 2011, by and among Midcap Financial SBIC, LP ((“MidCap”) as a
“Lender” and as “Agent” for the “Lenders” from time to time party thereto, the “Lenders” party thereto from time to time (in the case of the Agent and Lenders, together with their successors and assigns) and
the Company, as “Borrower”, as the same may be amended, restated, supplemented or otherwise modified from time to time, the “Senior LSA”) or any other Loan Documents (as defined in the Senior LSA) entered into in
connection therewith, all in accordance with and subject to the terms and conditions of that certain Subordination Agreement, dated May 3, 2012, by and among MidCap, each Purchaser and the Company (the “Subordination
Agreement”). Each person that becomes a Purchaser under the Purchase Agreement agrees to, either on or prior to the date such person becomes a Purchaser, execute a joinder to the Subordination Agreement in accordance with its terms.

 13. Governing Law. This Note is being delivered in and shall be construed in accordance with the laws of the State of
Delaware, without regard to the conflicts of laws provisions thereof. 
 14. Loss of Note. Upon receipt by the Company of
evidence satisfactory to it of the loss, theft, destruction or mutilation of this Note or any Note exchanged for it, and indemnity satisfactory to the Company (in case of loss, theft or destruction) or surrender and cancellation of such Note (in the
case of mutilation), the Company, at no cost to the Holder, will make and deliver in lieu of such Note a new Note of like tenor. 
 15. Equal Ranking. This Note shall rank equally without preference or priority of any kind over one another, and all payments on account of principal and interest with respect to any of the Notes
shall be applied ratably and proportionally on all outstanding Notes on the basis of the original principal amount of outstanding Notes. 
 16. Amendment. Any term of this Note may be amended only with the written consent of the Company and the holders of Notes of like tenor representing at least a majority of the outstanding aggregate
principal loan amount issued pursuant to the Purchase Agreement (all Notes issued pursuant to the Purchase Agreement are collectively referred to as the “Bridge Notes”); provided, however, that any such amendment or
waiver that disproportionately affects any of the holders of the Bridge Notes shall require the written consent of all such holders. Any amendment or waiver effected in accordance with this Section 16 shall be binding upon each holder of any
Bridge Note, each future holder of all such Bridge Notes and the Company, and the Company shall promptly give notice to all holders of outstanding Bridge Notes of any amendment or waiver effected in accordance with this Section 16. 

17. Transfer. The terms and conditions of this Note shall inure to the benefit of and be binding upon the respective successors
and assigns of the parties. This Note may be transferred only upon surrender of the original Note for registration of transfer, duly endorsed, or accompanied by a duly executed written instrument of transfer in form satisfactory to the Company.

RECITALS: 

WHEREAS, the Company desires to raise capital to expand its operations and capitalize on business opportunities;

 WHEREAS, in connection therewith, the existing bridge notes issued by the Company in the amounts set forth beside each holder’s (referred to herein as the “Noteholders” or

 NOW, THEREFORE, in consideration of the mutual promises and covenants set forth in this Agreement, and intending to be legally bound, the parties agree as follows: 

 

	SECTION 1.	PURCHASE AND SALE OF STOCK. 

 1.1 Sale
of Series E Preferred Stock. 
 (a) The Company shall adopt and file with the Secretary of State of the State of Delaware
before the Initial Closing (as defined below) the Fifth Amended and Restated Certificate of Incorporation in the form attached hereto as Exhibit A (the “Restated Certificate”). 

(b) Subject to the terms and conditions of this Agreement, each Investor agrees, individually and severally (but not jointly), to
purchase at each Closing, and the Company agrees to sell and issue to each such Investor at such Closing, that number of shares of the Company’s Series E Preferred Stock (the “Shares”) set forth opposite the Investor’s
name on Schedule A hereto at the purchase price set forth opposite the Investor’s name on Schedule A hereto. The Shares will have the rights, preferences, privileges and restrictions set forth in the Restated Certificate.

 (c) The Company hereby acknowledges that the proceeds from the sale of the Shares shall be used for research and development
activities associated with advancing the Company’s 

 
pipeline of product candidates (with over fifty percent (50%) of the proceeds to be used for further development of REG1 in its PCI indication) and working capital and capital expenditures
and other corporate purposes. 
 1.2 Initial Closing. 
 (a) The initial purchase and sale of up to 70,528,086 shares of Series E Preferred Stock (as specified on Schedule A attached hereto) shall take place in up to three (3) tranches either
remotely via the exchange of documents and signatures, or at the offices of Lowenstein Sandler PC, 1251 Avenue of the Americas, New York, New York 10020, as set forth on Schedule A (collectively, the “Initial Closing”).

 (i) First Tranche. The closing of the first tranche of the Initial Closing shall take place on December 18, 2012.

 (ii) Second Tranche. The closing of the second tranche of the Initial Closing shall take place on or before
March 14, 2013. The Board of Directors of the Company shall give written notice thereof to all Investors specifying therein the date of the closing of such second tranche (the “Second Tranche Notice”), which second
tranche closing shall be held no less than fifteen (15) days after the Second Tranche Notice has been deemed to have been given pursuant hereto (but in no event later than March 14, 2013). The total amount sold in the second tranche
of the Initial Closing shall be equal the amounts set forth on Schedule A except, if decided by a unanimous vote of the Board of Directors that a lesser amount should be called in the second tranche of the Initial Closing in which case the
difference between the said amounts and the total amounts on Schedule A will be applied to the closing of the third tranche of the Initial Closing. 
 (iii) Third Tranche. The closing of the third tranche of the Initial Closing shall take place, on or before January 17, 2014, subject to the prior unanimous written approval of the Major
Holders (as defined in this Section 1.2(a)(iii)) on or before December 31, 2013. If the Major Holders unanimously elect and agree to hold a closing of the third tranche of the Initial Closing, the Major Holders shall give written
notice thereof to the Company and all other Investors specifying therein the date of the closing of such third tranche (the “Third Tranche Notice”), which third tranche closing shall be held no less than fifteen (15) days after
the Third Tranche Notice has been deemed to have been given pursuant hereto (but in any event on or before January 17, 2014). In such event, each Investor listed on Schedule A hereto under the heading “Third Tranche of Initial
Closing (on or before January 17, 2014)” shall purchase (and is hereby committing to purchase) the number of Shares set forth opposite its name under such heading. For purposes of this Section 1.2(a)(iii) and Section 9.16
hereof only, the term “Major Holders” shall mean and include each holder of at least five percent (5%) of the then outstanding shares of the Preferred Stock of the Company regardless of series (it being understood that
(A) for purposes of determining if a holder is a Major Holder (1) such threshold shall be calculated based solely on outstanding shares of Preferred Stock on an as-converted to Common Stock basis, and (2) shares of Common Stock
actually issued upon conversion of any series of Preferred Stock shall not be taken into account and (B) any vote of the Major Holders pursuant to this Section 1.2 shall be by individual holder and not based on the voting power of the
Preferred Stock held by such holder). 

  
 2 

 (b) At the closing of each tranche of the Initial Closing, the Company shall deliver to each
Investor a certificate representing the shares of Series E Preferred Stock that such Investor is purchasing at the closing of the applicable tranche of the Initial Closing as set forth on Schedule A against payment of the purchase price
therefor by wire transfer to a non-interest bearing client trust bank account maintained by Lowenstein Sander PC (“Lowenstein”), by check or by cancellation of indebtedness (including accrued interest) or by any combination
thereof. Upon receipt of the full amount of the purchase price from all Investors (other than those who pay by check and/or by cancellation of indebtedness) at the closing of each tranche of the Initial Closing as set forth on Schedule
A, and satisfaction of the closing conditions set forth in Section 4, as confirmed by the certificate delivered by the Company to the Investors as set forth in Section 4(A)4.3, Section 4(B)4.3 or Section 4(C)4.3, as
applicable, Lowenstein, acting as the escrow agent, shall release the aggregate purchase price received from the Investors to the Company no later than two (2) business days after the receipt of all of the funds for such applicable tranche and
all checks delivered in payment therefor shall be deemed released to the Company contemporaneously therewith. In the event that payment by an Investor is made at the closing of the first tranche of the Initial Closing, in whole or in part, by
cancellation of indebtedness, then such Investor shall surrender to the Company for cancellation at the closing of the first tranche of the Initial Closing any evidence of such indebtedness or shall execute an instrument of cancellation in form and
substance reasonably acceptable to the Company. In the event that the full amount of the purchase price (including payment consideration paid by check or by cancellation of indebtedness) is not received within five (5) business days of the
proposed closing of the applicable tranche, as set forth on Schedule A, then (1) Lowenstein, as the escrow agent, shall promptly return all funds so delivered by Investors to its escrow account to such Investors in the amounts provided
by each such Investor in connection with the closing of such applicable tranche, without interest, and (2) the Company will return to each Investor who paid by check its or his check and to all Investor who hold notes that otherwise would have
been converted into Shares at the first tranche of the Initial Closing their convertible promissory notes (which notes shall not be deemed to have been cancelled and shall continue in full force and effect in accordance with their terms).

 1.3 Second Closing. 
 (a) Subject to the terms and conditions of this Agreement, the second purchase and sale of Series E Preferred Stock (as specified on Schedule A attached hereto) shall take place on or before
June 30, 2013 (the “Second Closing”, together with the Initial Closing, each a “Closing”), upon such date determined by the Board of Directors of the Company, who shall determine the Second Closing Date no
later than June 15, 2013. The Company shall provide the Investors with written notice of the date of the scheduled Second Closing at least fifteen (15) days prior to the scheduled Second Closing. The date of the Second Closing is herein
referred to as the “Second Closing Date.” The parties hereto agree that the Investors participating in the Initial Closing may, but are not required to, participate in the Second Closing up to the full amount of their pro rata share
of the funds to be invested therein. At the Second Closing, RMI (as defined below) shall match any and all investment proceeds by an aggregate amount of up to $6,000,000 subject to satisfaction of RMI’s condition as set forth in Sections
4(B)4.7, 4(C)4.6 and 6.6 of this Agreement (“RMI’s condition”). In the event that the aggregate amount of non-RMI investment proceeds received by the Company exceeds $6,000,000 RMI agrees to use its commercially reasonable
efforts to obtain additional financing to match such extension. 

  
 3 

 (b) At the Second Closing, the Company shall deliver to each purchaser participating therein
a certificate representing the shares of Series E Preferred Stock that such Investor is purchasing at the Second Closing (the “Second Closing Shares”) against payment of the purchase price therefor by wire transfer or check to a
non-interest bearing client trust bank account maintained by Lowenstein, by check or by a combination of the foregoing. Upon receipt of the full amount of the purchase price at the Second Closing from all Investors (other than those who pay by
check) and satisfaction of the closing conditions set forth in Section 6, as confirmed by the certificate delivered by the Company to the Investors as set forth in Section 6.4, Lowenstein, acting as the escrow agent, shall release an
amount equal to the aggregate purchase price received from the Investors to the Company no later than two (2) business days after the receipt of the funds in connection with the Second Closing and all checks delivered in payment therefor shall
be deemed to be released to the Company contemporaneously therewith. In the event that the full amount of the purchase price is not received within five (5) business days of the scheduled Second Closing, then Lowenstein, as the escrow
agent, shall return all funds to the Investors in the amounts provided by each Investor in connection with the Second Closing, without interest and the Company will return to each Investor who paid by check its or his check.

1.4 RMI Investment. 

Subject to the terms and conditions to this Agreement, RMI Investments, S.a.r.l. (“RMI”) shall match the investment
amount of non-RMI Investors at any Closing and pursuant to Section 1.5 by an amount equal to 100% of the funds invested by all non-RMI Investors as set forth in Schedule A of this Agreement received in cash by the Company (up to $31,200,000 in
the aggregate under this Agreement) and subject to satisfaction of the RMI’s condition. For clarity, RMI shall not be obliged to match an amount of investment provided by any non-RMI Investor at any Closing, in the event that the Company did
not receive an amount equal to the full amount of the purchase price specified in Schedule A of this Agreement at or, as permitted under Section 1.5 below, prior to the applicable closing of each tranche of the Initial Closing and the
full amount of the purchase price specified in Section 1.3 of this Agreement at the Second Closing. As set forth in Sections 1.2(a), and 1.3(a) hereof, the Company shall promptly notify RMI in writing about the amount of investments received by
the Company from any such non-RMI Investor. 
 1.5. Right to Purchase Shares. 

Notwithstanding anything herein to the contrary, any Investor may, in its sole discretion, purchase any part or all of the Shares that
otherwise would be purchasable at the third tranche of the Initial Closing Shares and, subject to the Board of Directors prior written consent, purchase any Second Closing Shares at any time prior to the closing of the third tranche of the Initial
Closing or prior to the Second Closing Date (as applicable) upon thirty (30) calendar days’ prior written notice to the Company and RMI. As set forth in Section 1.4 hereof, RMI shall match the investment amount of all non-RMI
Investors pursuant to this Section 1.5 and Section 1.4. It is understood and agreed that, unless such additional purchase occurs simultaneously with the closing of any of the tranches of the Initial Closing or the Second Closing, the date
of any such purchase shall not be deemed a “Closing” for any purpose hereunder and, without limiting the foregoing, none of the conditions to closing set forth in Section 4 hereof shall apply to any such

  
 4 

 
purchase and sale except that upon receipt of funds representing the purchase price for the such Shares, the Company shall deliver to the Investor a certificate representing such Shares. If the
Shares otherwise purchasable at the third tranche of the Initial Closing are purchased prior to the closing of the second tranche of the Initial Closing, RMI shall not be obligated to match the investment thereof unless and until (but simultaneously
with) the closing of the second tranche of the Initial Closing. In the event that RMI matches investments of any non-RMI Investor, the amount of the respective investment of RMI set forth in Schedule A shall be decreased on the amount of funds
transferred by RMI to the Company pursuant to the Section 1.4 and 1.5 of this Agreement. 
 1.6 Further Assurances. At and after
each Closing, the Company and each Investor agree to take and do such further actions and things reasonably required consummate the purchase, sale, surrender and/or exchange of securities contemplated hereby. 

 

	SECTION 2.	REPRESENTATIONS AND WARRANTIES OF THE COMPANY. 

 The Company hereby represents and warrants to the Investors that, as of each Closing, except as set forth on a schedule of exceptions attached hereto as Schedule B (the “Schedule of
Exceptions”) specifically identifying the relevant subparagraphs of this Section 2 (provided, however, that disclosure by reference to one or more sections shall constitute disclosure for all purposes under this Section 2 if such
disclosure, reasonably construed, provides the Investors with effective disclosure; provided further, however, that any disclosure relating to Intellectual Property Assets shall be specifically mentioned in Section 2.19 of Schedule B or shall
be specifically cross-referenced in Section 2.19 if disclosed in another Section of Schedule B), which exceptions shall be deemed to be representations and warranties as if made hereunder: 

For purposes of this Section 2, the term “Shares” shall mean all shares of Series E Preferred Stock to be sold and
issued at the Initial Closing. For the avoidance of doubt, for purposes of this Section 2, the term “Shares” shall not include the shares of Series E Preferred Stock to be issued at the Second Closing. 

2.1 Organization; Power; Good Standing; Qualification. The Company is a corporation duly organized, validly existing, and in good standing under
the laws of the State of Delaware, has all requisite corporate power and authority to own and operate its properties and assets and to carry on its business as now conducted and as presently proposed to be conducted, to execute and deliver this

waste. The Company has not received any official or formal notification of any current, pending or outstanding violation of environmental laws by any previous occupants of the premises currently leased by the Company.

to all transactions referred to in such minutes in all material respects.

coverage and the material terms and provisions of such policy, (iii) the annual premium and cash value (if any), and (iv) a description of any past claims or claims pending. The insurance carried by the Company with respect to its

and (iii) has not waived any statute of limitations with respect to taxes or agreed to any extension of time with respect to a tax assessment or deficiency. The assessment of any additional taxes for periods for which returns have been filed is

reviewed or audited by any federal, state, local or county taxing authority. There is no pending dispute with any taxing authority relating to any of said returns which, if determined adversely to the Company, would result in the assertion by any
taxing authority of any valid deficiency in any material amount for taxes. No written claim has ever been made by any authority in a jurisdiction where the Company does not file tax returns that the Company is or may be subject to taxation by that
jurisdiction. Since the most recent Financial Statements, the Company has not incurred any material taxes other than in the ordinary course of business. The Company does not have any liability for the taxes of any other person (other than its
wholly-owned subsidiaries) pursuant to the requirements of law, contract, intercompany arrangement or otherwise. The Company is not a “United States real property holding corporation” (within the meaning of section 897(c)(2) of the Code).

appointive office of any governmental authority. The Company has not committed a violation of the Foreign Corrupt Practices Act of 1977.

Investor is an “accredited investor” within the meaning of Rule 501 of Regulation D adopted pursuant to the Securities Act. 
 3.7
Restricted Securities. Such Investor understands that the Securities may not be sold, transferred, or otherwise disposed of without registration under the Securities Act or an exemption therefrom, and that in the absence of an effective
registration statement covering the Securities or an available exemption from registration under the Securities Act, the Securities must be held indefinitely. In particular, the Investor is aware that the Securities may not be sold pursuant to Rule
144 promulgated under the Securities Act unless all of the conditions of that Rule are met. Among the conditions for use of Rule 144 may be the availability of current information to the public about the Company. Such information is not now

issued upon conversion thereof shall be endorsed with the legends substantially in the form set forth below:

COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.” 
 (b) Any legend imposed or required by the Company’s Bylaws (as

 9.2 Indemnification. The Company shall indemnify, defend and hold each Investor harmless from and against all claims, liabilities, losses, and damages paid, incurred, accrued or sustained by an
Investor, directly or indirectly, together with all reasonable costs and expenses related thereto (including, without limitation, reasonable legal and accounting fees and expenses) as a result of (a) any breach or inaccuracy of a representation

or agreement of the Company in the Ancillary Agreements; provided however, that the aggregate liability of the Company to each Investor under this Section 9.2 shall not exceed the aggregate purchase price of the Series E Preferred Stock
