confidentiality, disclosure or proprietary information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant which would have a Material Adverse Effect, and the continued employment of each such
executive officer does not subject the Company or any Subsidiary to any liability with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance with all U.S. federal, state, local and foreign laws and regulations
relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in compliance would not, individually or in the aggregate, have a Material Adverse Effect.

any court, arbitrator or governmental body having jurisdiction over the Company or its properties or assets, or (iii) is or has been in violation of, or in receipt of written notice that it is in violation of, any statute, rule or regulation of

 (p) Regulatory Permits. The Company and each of its Subsidiaries possess all certificates, authorizations and permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary
to conduct its respective business as described in the SEC Reports, except where the failure to possess such permits, individually or in the aggregate, has not and would not have, individually or in the aggregate, a Material Adverse Effect
(“Material Permits”), and (i) neither the Company nor any of its Subsidiaries has received any notice of proceedings relating to the revocation or modification of any such Material Permits and (ii) the Company is unaware
of any facts or circumstances that the Company would reasonably expect to give rise to the revocation or modification of any Material Permits.

each case free and clear of all Liens except such as do not materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company and any of its Subsidiaries. Any real property
and facilities held under lease by the Company and any of its Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of

technology, Internet domain names, know-how and other intellectual property (collectively, the “Intellectual Property”) necessary for the conduct of their respective businesses as now conducted or as proposed to be conducted. Except
as set forth in the SEC Reports and except where such violations or infringements would not have, either individually or in the aggregate, a Material Adverse Effect, (a) there are no rights of third parties to any such Intellectual Property;
(b) to the Company’s Knowledge, there is no infringement by third parties of any such Intellectual Property; (c) there is no pending or, to the Company’s Knowledge, threatened in writing action, suit, proceeding or claim by

of the transactions contemplated by this Agreement, any valid right, interest or claim against or upon the Company or a Purchaser for any commission, fee or other compensation pursuant to any agreement, arrangement or understanding entered into by
or on behalf of the Company, other than the Placement Agent with respect to the offer and sale of the Shares (which placement agent fees are being paid by the Company). The Company shall indemnify, pay, and hold each Purchaser harmless against, any
liability, loss or expense (including, without limitation, attorneys’ fees and out-of-pocket expenses) arising in connection with any such right, interest or claim.

 (z) No Directed Selling Efforts or General Solicitation. Neither the Company, nor any of its Affiliates, nor any
Person acting on its or their behalf has conducted any “general solicitation” or “general advertising” (as those terms are used in Regulation D) in connection with the offer or sale of any of the Shares. 
 (aa) No Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in
Section 3.2, none of the Company, its Subsidiaries nor any of their Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, at any time within the past six months, made any offers or sales of any Company security
or solicited any offers to buy any security under circumstances that would (i) eliminate the availability of the exemption from registration under Regulation D under the Securities Act in connection with the offer and sale by the Company of the
Shares as contemplated hereby or (ii) cause the offering of the Shares pursuant to the Transaction Documents to be integrated with prior offerings by the Company for purposes of any applicable law, regulation or shareholder approval provisions,

 (c) Investment Intent. Such Purchaser understands that the Shares are “restricted securities” and have not been
registered under the Securities Act or any applicable state securities law and is acquiring the Shares as principal for its own account and not with a view to, or for distributing or reselling such Shares or any part thereof in violation of the

prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed

 ARTICLE IV. 
 OTHER AGREEMENTS OF THE PARTIES 
 4.1 Transfer Restrictions. 
 (a) Compliance with Laws. Notwithstanding any other provision of this Article IV, each Purchaser covenants that the Shares may be
disposed of only pursuant to an effective registration statement under, and in compliance with the requirements of, the Securities Act, or pursuant to an available exemption from, or in a transaction not subject to, the registration requirements of
the Securities Act, and in compliance with any applicable state and federal securities laws. In connection with any transfer of the Shares other than (i) pursuant to an effective registration statement, (ii) to the Company,
(iii) pursuant to Rule 144 (provided that the Purchaser provides the Company with reasonable assurances (in the form of seller and broker representation letters) that the securities may be sold pursuant to such rule) or
(iv) pursuant to Rule 144(k) following the applicable holding period (provided that the Purchaser provides the Company with reasonable assurances in a representation letter that the securities may be sold pursuant to such rule), the
Company may require the transferor thereof to provide to the Company and the Transfer Agent an opinion of counsel selected by the transferor and reasonably acceptable to the Company and the Transfer Agent, the form and substance of which opinion
shall be reasonably satisfactory to the Company and the Transfer Agent, to the effect that such transfer does not require registration of such transferred Shares under the Securities Act. As a condition of transfer, any such transferee shall agree
in writing to be bound by the terms of this Agreement and shall have the rights of a Purchaser under this Agreement and the Registration Rights Agreement. 
 (b) Legends. Certificates evidencing the Shares shall bear any legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form, until such time as
they are not required under Section 4.1(c): 
 THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE “SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE
SECURITIES ACT OR (B) AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS AS EVIDENCED BY A LEGAL OPINION
OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY AND ITS TRANSFER AGENT OR (II) UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT. 
 The Company acknowledges and agrees that a Purchaser may from time to time pledge, and/or grant a security interest in, some or all of the legended Shares in connection with applicable securities laws, pursuant to a bona fide margin
agreement in compliance with a bona fide margin loan. Such a pledge would not be subject to approval or consent of the Company and no legal opinion of legal counsel to the pledgee, secured party or pledgor shall be required in connection with the
pledge, but such legal opinion shall be required in connection with a subsequent transfer or foreclosure following default by the Purchaser transferee of the pledge. No notice shall be required of such pledge, but Purchaser’s transferee shall
promptly notify the Company of any such subsequent transfer or foreclosure. Each Purchaser acknowledges that the Company shall not be responsible for any pledges relating to, or the grant of any security interest in, any of the Shares or for any
agreement, understanding or arrangement 

  

 19 







 
between any Purchaser and its pledgee or secured party. At the appropriate Purchaser’s expense, the Company will execute and deliver such reasonable
documentation as a pledgee or secured party of Shares may reasonably request in connection with a pledge or transfer of the Shares, including the preparation and filing of any required prospectus supplement under Rule 423(b)(3) of the Securities Act
or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders thereunder. Each Purchaser acknowledges and agrees that, except as otherwise provided in Section 4.1(c), any Shares subject to a pledge
or security interest as contemplated by this Section 4.1(b) shall continue to bear the legend set forth in this Section 4.1(b) and be subject to the restrictions on transfer set forth in Section 4.1(a). 
 (c) Removal of Legends. The legend set forth in Section 4.1(b) above shall be removed and the Company shall issue a
certificate without such legend or any other legend to the holder of the applicable Shares upon which it is stamped or issue to such holder by electronic delivery at the applicable balance account at the Depository Trust Company
(“DTC”), if (i) such Shares are registered for resale under the Securities Act, (ii) such Shares are sold or transferred pursuant to Rule 144 (assuming the transferor is not an Affiliate of the Company), or (iii) such
Shares are eligible for sale under Rule 144(k). The Company shall cause Company Counsel to issue the legal opinion referred to in the Irrevocable Transfer Agent Instructions to the Company’s transfer agent on the Effective Date. Any fees (with
respect to the Transfer Agent, Company Counsel or otherwise) associated with the issuance of such opinion or the removal of such legend shall be borne by the Company. Following the Effective Date, or at such earlier time as a legend is no longer
required for certain Shares, the Company will use its best efforts to cause the Transfer Agent, no later than three (3) Trading Days following the delivery by a Purchaser to the Transfer Agent (with notice to the Company) of a legended
certificate representing such Shares (endorsed or with stock powers attached, signatures guaranteed, and otherwise in form necessary to affect the reissuance and/or transfer) (such third Trading Day, the “Legend Removal Date”), to
deliver or cause to be delivered to such Purchaser a certificate representing such Shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to the Transfer Agent that
enlarge the restrictions on transfer set forth in this Section. Certificates for Shares subject to legend removal hereunder may be transmitted by the Transfer Agent to the Purchasers by crediting the account of the Purchaser’s prime broker with
DTC. 
 (d) Irrevocable Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer
agent, and any subsequent transfer agent, to issue certificates registered in the name of each Purchaser or its respective nominee(s), for the Shares in such amounts as specified from time to time by each Purchaser to the Company in the form of
Exhibit D attached hereto (the “Irrevocable Transfer Agent Instructions”). The Company represents and warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 4.1(d)
will be given by the Company to its transfer agent in connection with this Agreement, and that the Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the other
Transaction Documents. The Company acknowledges that a breach by it of its obligations under this Section 4.1(d) will cause irreparable harm to a Purchaser. Accordingly, the Company acknowledges that the remedy at law for a breach of its
obligations under this Section 4.1(d) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 4.1(d), that a Purchaser shall be entitled, in addition to all other
available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required. 
 (e) Acknowledgement. Each Purchaser hereunder acknowledges its primary responsibilities under the Securities Act and accordingly
will not sell the Shares or any interest therein without complying with the requirements of the Securities Act. While the above-referenced registration statement remains effective, each Purchaser hereunder may sell the shares in accordance with the
plan of 

  

 20 







 
distribution contained in the registration statement and if it does so it will comply therewith and with the related prospectus delivery requirements unless
an exemption therefrom is available. Each Purchaser, severally and not jointly with the other Purchasers, agrees that if it is notified by the Company in writing at any time after the date any legend is removed pursuant to Section 4.1(c) hereof
that the registration statement registering the resale of the Shares is not effective or that the prospectus included in such registration statement no longer complies with the requirements of Section 10 of the Securities Act, the Purchaser
will refrain from selling such Shares until such time as the Purchaser is notified by the Company that such registration statement is effective or such prospectus is compliant with Section 10 of the Exchange Act, unless such Purchaser is able
to, and does, sell such Shares pursuant to an available exemption from the registration requirements of Section 5 of the Securities Act. Both the Company and its Transfer Agent, and their respective directors, officers, employees and agents,
may rely on this subsection (e) and each Purchaser hereunder will indemnify and hold harmless each of such persons from any breaches or violations of this paragraph. 
 4.2 Acknowledgment of Dilution. The Company acknowledges that the issuance of the Shares may result in dilution of the outstanding shares of Common Stock, which dilution may be substantial under certain
market conditions. The Company further acknowledges that its obligations under the Transaction Documents, including without limitation its obligation to issue the Shares pursuant to the Transaction Documents, are unconditional and absolute and
not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim the Company may have against any Purchaser and regardless of the dilutive effect that such issuance may have on the
ownership of the other shareholders of the Company. 
 4.3 [Reserved.] 
 4.4 Form D and Blue Sky. The Company agrees to timely file a Form D with respect to the Shares as required under Regulation D. The Company, on or
before the Closing Date, shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Shares for sale to the Purchasers at the Closing pursuant to this Agreement under applicable
securities or “Blue Sky” laws of the states of the United States (or to obtain an exemption from such qualification). The Company shall make all filings and reports relating to the offer and sale of the Shares required under applicable
securities or “Blue Sky” laws of the states of the United States following the Closing Date. 
 4.5 No Integration. The
Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that will be integrated with the offer or sale of the Shares in a manner that
would require the registration under the Securities Act of the sale of the Shares to the Purchasers, or that will be integrated with the offer or sale of the Shares for purposes of the rules and regulations of any Trading Market such that it would
require shareholder approval prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction. 
 4.6 Securities Laws Disclosure; Publicity. By 9:00 a.m., New York City time, on the Trading Day immediately following the execution of this Agreement, the Company shall issue a press release (the “Press
Release”) reasonably acceptable to the Placement Agent disclosing all material terms of the transactions contemplated hereby. On or before 9:00 a.m., New York City time, on the second Trading Day following the execution of this Agreement
(or such earlier time as required by law), the Company will file a Current Report on Form 8-K with the Commission describing the terms of the Transaction Documents (and including as exhibits to such Current Report on Form 8-K the material
Transaction Documents (including, without limitation, this Agreement and the Registration Rights Agreement)). Notwithstanding the foregoing, the Company shall not publicly disclose the name of any 

  

 21 







 
Purchaser or an Affiliate of any Purchaser, or include the name of any Purchaser or an Affiliate of any Purchaser in any press release or filing with the
Commission (other than the Registration Statement) or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except (i) as required by federal securities law in connection with (A) any registration
statement contemplated by the Registration Rights Agreement and (B) the filing of final Transaction Documents (including signature pages thereto) with the Commission and (ii) to the extent such disclosure is required by law, request of the
Staff of the Commission or Trading Market regulations, in which case the Company shall provide the Purchasers with prior written notice of such disclosure permitted under this subclause (ii). Each Purchaser, severally and not jointly with the other
Purchasers, covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company as described in this Section 4.6, such Purchaser will maintain the confidentiality of all disclosures made to it
in connection with this transaction (including the existence and terms of this transaction). 
 4.7 Non-Public Information. Except
with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company shall not, and shall cause each Subsidiary and each of their respective officers, directors, employees and agents, not to,
provide any Purchaser with any material, non-public information regarding the Company or any of its Subsidiaries from and after the filing of the Press Release without the express written consent of such Purchaser, unless prior thereto such
Purchaser shall have executed a written agreement regarding the confidentiality and use of such information. 
 4.8 Indemnification.

 (a) Indemnification of Purchasers. In addition to the indemnity provided in the Registration Rights Agreement, the
Company will indemnify and hold each Purchaser and its directors, officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of
such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners or
employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling person (each, a “Purchaser Party”) harmless from any
and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser
Party may suffer or incur as a result of or relating to third party claims against such Purchaser relating to any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other
Transaction Documents. The Company will not be liable to any Purchaser Party under this Agreement to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the
representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents or any agreements or understandings such Purchaser may have with any shareholder or any violations by the
Purchaser of state or federal securities laws or any conduct by such Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance. 
 (b) Conduct of Indemnification Proceedings. Promptly after receipt by any Person (the “Indemnified Person”)
of notice of any demand, claim or circumstances which would or might give rise to a claim or the commencement of any action, proceeding or investigation in respect of which indemnity may be sought pursuant to Section 4.8(a), such Indemnified
Person shall promptly notify the Company in writing and the Company shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such Indemnified Person, and shall assume the payment of all fees and expenses;
provided, however, that the failure of any Indemnified Person so to notify the Company shall not relieve the Company of its obligations hereunder except to the extent that the Company is actually and 

  

 22 







 
materially prejudiced by such failure to notify. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Person unless: (i) the Company and the Indemnified Person shall have mutually agreed to the retention of such counsel; (ii) the Company shall have failed promptly to
assume the defense of such proceeding and to employ counsel reasonably satisfactory to such Indemnified Person in such proceeding; or (iii) in the reasonable judgment of counsel to such Indemnified Person, representation of both parties by the
same counsel would be inappropriate due to actual or potential differing interests between them. The Company shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably
withheld, delayed or conditioned. Without the prior written consent of the Indemnified Person, which consent shall not be unreasonably withheld, delayed or conditioned, the Company shall not effect any settlement of any pending or threatened
proceeding in respect of which any Indemnified Person is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Person from
all liability arising out of such proceeding. 
 4.9 Listing of Securities. Prior to the execution of this Agreement or promptly
following the date hereof, the Company shall have taken or shall take all necessary action to cause the Shares to be listed upon the Principal Trading Market, if any, upon which shares of Common Stock are then listed (subject to official notice of
issuance) and shall maintain, so long as any other shares of Common Stock shall be so listed, such listing. Further, if the Company applies to have its Common Stock or other securities listed on any other Trading Market, it shall include in such
application the Shares and will take such other action as is necessary to cause the Shares to be listed on such other Trading Market as promptly as practicable. 
 4.10 Use of Proceeds. The Company intends to use the net proceeds from the sale of the Shares hereunder for working capital and general corporate purposes and not to redeem any Common Stock or Common Stock
Equivalents or to settle any outstanding Action. 
 4.11 Short Sales After The Date Hereof. Such Purchaser shall not, and shall cause
its Trading Affiliates not to, engage, directly or indirectly, in any Short Sales involving the Company’s securities during the period from the date hereof until the earlier of such time as (i) the transactions contemplated by this
Agreement are first publicly announced as described in Section 4.6 or (ii) this Agreement is terminated in full pursuant to Section 6.18. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment
vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such
Purchaser’s assets, the representation set forth above shall apply only with respect to the portion of assets managed by the portfolio manager that have knowledge about the financing transaction contemplated by this Agreement. Each Purchaser
understands and acknowledges, severally and not jointly with any other Purchaser, that the Commission currently takes the position that covering a short position established prior to effectiveness of a resale registration statement with shares
included in such registration statement would be a violation of Section 5 of the Securities Act, as set forth in Item 65, Section 5 under Section A, of the Manual of Publicly Available Telephone Interpretations, dated July 1997,
compiled by the Office of Chief Counsel, Division of Corporation Finance.

 26 







 6.5 Construction. The headings herein are for convenience only, do not constitute a part of this
Agreement and shall not be deemed to limit or affect any of the provisions hereof. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will
be applied against any party. This Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement
or any of the Transaction Documents. 
 6.6 Successors and Assigns. The provisions of this Agreement shall inure to the benefit of and
be binding upon the parties and their successors and permitted assigns. This Agreement, or any rights or obligations hereunder, may not be assigned by the Company without the prior written consent of the Purchasers. Any Purchaser may assign its
rights hereunder in whole or in part to any Person to whom such Purchaser assigns or transfers any Shares in compliance with the Transaction Documents and applicable law, provided such transferee shall agree in writing to be bound, with respect to
the transferred Shares, by the terms and conditions of this Agreement that apply to the “Purchasers”. 
 6.7 No Third-Party
Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except
(i) each Purchaser Party is an intended third party beneficiary of Section 4.8, and (ii) the Placement Agent is an intended third party beneficiary of Article III hereof, and each Purchaser Party or the Placement Agent, as the case
may be, may enforce the provisions of such Sections directly against the parties with obligations thereunder . 
 6.8 Governing Law.
All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of
conflicts of law thereof. Each party agrees that all Proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto
or its respective Affiliates, employees or agents) shall be commenced exclusively in the New York Courts. Each party hereto hereby irrevocably submits to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder
or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Proceeding, any
claim that it is not personally subject to the jurisdiction of any such New York Court, or that such Proceeding has been commenced in an improper or inconvenient forum. Each party hereto hereby irrevocably waives personal service of process and
consents to process being served in any such Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and
agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HERETO HEREBY
IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
 6.9 Survival. Subject to applicable statute of limitations, the representations, warranties, agreements and covenants contained herein shall
survive the Closing and the delivery of the Shares. 
 6.10 Execution. This Agreement may be executed in two or more counterparts, all
of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both 

  

 27 







 
parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission, or by e-mail delivery of a
“.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile signature page were an original
thereof. 
 6.11 Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity
and enforceability of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor,
and upon so agreeing, shall incorporate such substitute provision in this Agreement. 
 6.12 Rescission and Withdrawal Right.
Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does
not timely perform its related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in
whole or in part without prejudice to its future actions and rights 
 6.13 Replacement of Shares. If any certificate or instrument
evidencing any Shares is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument,
but only upon receipt of evidence reasonably satisfactory to the Company and the Transfer Agent of such loss, theft or destruction and the execution by the holder thereof of a customary lost certificate affidavit of that fact and an agreement to
indemnify and hold harmless the Company and the Transfer Agent for any losses in connection therewith or, if required by the Transfer Agent, a bond in such form and amount as is reasonably required by the Transfer Agent. The applicants for a new
certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Shares. If a replacement certificate or instrument evidencing any Shares is requested due to a
mutilation thereof, the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement. 
 6.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific
performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agree to waive in any
action for specific performance of any such obligation (other than in connection with any action for a temporary restraining order) the defense that a remedy at law would be adequate. 
 6.15 Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction Document or a
Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered
from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable
cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or
setoff had not occurred. 
  

 28 







 6.16 Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision,
dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or
event occurring after the date hereof, each reference in any Transaction Document to a number of shares or a price per share shall be deemed to be amended to appropriately account for such event. 
 6.17 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several
and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under any Transaction Document. The decision of each Purchaser to purchase
Shares pursuant to the Transaction Documents has been made by such Purchaser independently of any other Purchaser and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties,
liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or any Subsidiary which may have been made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser and
any of its agents or employees shall have any liability to any other Purchaser (or any other Person) relating to or arising from any such information, materials, statement or opinions. Nothing contained herein or in any Transaction Document, and no
action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert
or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment
hereunder and that no Purchaser will be acting as agent of such Purchaser in connection with monitoring its investment in the Shares or enforcing its rights under the Transaction Documents. Each Purchaser shall be entitled to independently protect
and enforce its rights, including without limitation the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for
such purpose. The Company acknowledges that each of the Purchasers has been provided with the same Transaction Documents for the purpose of closing a transaction with multiple Purchasers and not because it was required or requested to do so by any
Purchaser. The Company’s obligations to each Purchaser under this Agreement are identical to its obligations to each other Purchaser other than such differences resulting solely from the number of Shares purchased by such Purchaser, but
regardless of whether such obligations are memorialized herein or in another agreement between the Company and a Purchaser. 
 6.18
Termination. This Agreement may be terminated and the sale and purchase of the Shares abandoned at any time prior to the Closing by either the Company or any Purchaser (with respect to itself only) upon written notice to the other, if the
Closing has not been consummated on or prior to 5:00 p.m., New York City time, on the Outside Date; provided, however, that the right to terminate this Agreement under this Section 6.18 shall not be available to any Person whose failure
to comply with its obligations under this Agreement has been the cause of or resulted in the failure of the Closing to occur on or before such time. Nothing in this Section 6.18 shall be deemed to release any party from any liability for any
breach by such party of the terms and provisions of this Agreement or the other Transaction Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other
Transaction Documents. In the event of a termination pursuant to this Section, the Company shall promptly notify all non-terminating Purchasers. Upon a termination in accordance with this Section, the Company and the terminating Purchaser(s) shall
not have any further obligation or liability (including arising from such termination) to the other, and no Purchaser will have any liability to any other Purchaser under the Transaction Documents as a result therefrom.

 This Investor Questionnaire
(“Questionnaire”) must be completed by each potential investor in connection with the offer and sale of the shares of the common stock, par value $0.001 per share (collectively, the “Shares”), of AtriCure, Inc., a
Delaware corporation (the “Corporation”). The Shares are being offered and sold by the Corporation without registration under the Securities Act of 1933, as amended (the “Act”), and the securities laws of certain
states, in reliance on the exemptions contained in Section 4(2) of the Act and on Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws. The Corporation must determine that a potential investor
meets certain suitability requirements before offering or selling Shares to such investor. The purpose of this Questionnaire is to assure the Corporation that each investor will meet the applicable suitability requirements. The information supplied
by you will be used in determining whether you meet such criteria, and reliance upon the private offering exemptions from registration is based in part on the information herein supplied. 
 This Questionnaire does not constitute an offer to sell or a solicitation of an offer to buy any security. Your answers will be kept strictly confidential. However, by
signing this Questionnaire, you will be authorizing the Corporation to provide a completed copy of this Questionnaire to such parties as the Corporation deems appropriate in order to ensure that the offer and sale of the Shares will not result in a
violation of the Act or the securities laws of any state and that you otherwise satisfy the suitability standards applicable to purchasers of the Shares. All potential investors must answer all applicable questions and complete, date and sign this
Questionnaire. Please print or type your responses and attach additional sheets of paper if necessary to complete your answers to any item.

	 	Re:	Offering of 1,707,682 shares of Common Stock of AtriCure, Inc. 

 Ladies and Gentlemen: 
 We have acted as securities counsel to AtriCure, Inc., a Delaware corporation (the “Company”), in
connection with the issuance and sale of 1,707,682 shares of Common Stock, $0.001 par value (the “Shares”), of the Company pursuant to the Securities Purchase Agreement (the “Purchase Agreement”) dated as of May 24, 2007 by
and between the Company and the entities listed on Schedule A attached hereto (the “Investors”). We are delivering this opinion letter to you pursuant to Section 2.2(a)(iii) of the Purchase Agreement. Capitalized terms used in this
opinion letter, unless specifically defined in this opinion letter, have the meanings given them in the Purchase Agreement. 
 In connection
with rendering the opinions set forth below, we have examined and relied on originals or copies, certified or otherwise identified to our satisfaction, of the following documents: 
 (a) the Purchase Agreement (the “Purchase Agreement”); 
 (b) the Registration Rights Agreement (collectively with the Purchase Agreement, the “Agreements”); 
 (c) the certificate of incorporation (the “Certificate of Incorporation”) of the Company; 
 (d) the bylaws (the
“Bylaws”) of the Company; 
 (e) a certificate of good standing from the Secretary of State of the State of Delaware; and

 (f) such other documents, records, certificates of public officials and officers of the Company and instruments as we have deemed
necessary or appropriate for purposes of rendering the opinions set forth below. 
 With your permission we have assumed the following:
(a) the authenticity of original documents and genuineness of all signatures; (b) the conformity to the originals of all documents submitted to us as copies; (c) the truth, accuracy and completeness of the information, representations
and warranties contained in the records, documents, instruments and certificates we 







 
have reviewed; (d) except as specifically covered in the opinions set forth below, (i) the parties to the Agreements have all requisite power and
authority, and in the case of individuals, the capacity, to execute and deliver the Agreements, (ii) the due authorization, execution and delivery of the Agreements on behalf of such parties, and (iii) the valid and binding effect thereof
on such parties; and (e) the absence of any evidence extrinsic to the provisions of the written agreements between the parties that the parties intended a meaning contrary to that expressed by those provisions. 
 For purposes of our opinions in paragraphs 6 and 7 below, we have additionally relied upon and assumed, without independent investigation, the truth and
accuracy of the Company’s representations to us that (i) the Company has made no offer to sell the Shares or the shares of Common Stock issuable upon conversion of the Shares by means of any general solicitation or general advertising
within the meaning of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”) including, but not limited to, by means of (A) any advertisement, article, notice or other communication published in any
newspaper, magazine, or similar media or broadcast over television or radio and (B) any seminar or meeting whose attendees have been invited by any general solicitation or general advertising and (ii) the Company has made no offer to sell
or sale of the Shares, any shares of Common Stock or any other class of security exercisable for, exchangeable into or convertible into Common Stock since the date that is six months prior to the date hereof. 
 Based upon such examination and in reliance thereon and having regard for legal considerations which we deem relevant, subject to the assumptions set
forth above and the limitations and qualifications set forth below, we are of the following opinions: 
 1. The Company is a corporation
validly existing and in good standing under the law of the State of Delaware. 
 2. The Company has the corporate power to execute, deliver
and perform its obligations under the Agreements. 
 3. The Company has taken all corporate action necessary to authorize the execution,
delivery and performance by the Company of the Agreements, and has duly executed and delivered the Agreements. Each Agreement constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its terms.

 4. The Shares are duly authorized and, when issued and sold to the Investors in accordance with the terms of the Purchase Agreement and
delivered against payment therefor, will be validly issued, fully paid and non-assessable. The issuance of the Shares will not be subject to statutory preemptive rights of any shareholder of the Company. 
 5. The execution and delivery by the Company of the Agreements do not, and the Company’s performance of its obligations thereunder will not, except
as set forth in the Disclosure Schedules, (a) result in a violation of the Certificate of Incorporation or By-laws of the Company, in each case as in effect on the date hereof, (b) result in a violation of any law of the United States of
America or the State of New York, or any rule or regulation thereunder, applicable to the Company or its properties or assets, (c) except as set forth in the Agreements and except as may be required under state or other blue sky law or by the
National Association of Securities Dealers, Inc. (on which we express no opinion), require any authorization or order of, consent, waiver, approval of or other action, notice to or filing or registration or qualification with any Federal or New York
governmental authority, (d) except as set forth in the Agreements, breach or result in a default under any Material Contracts, or (e) result in the creation or imposition of any lien, security interest, charge or encumbrance on any asset
of the Company pursuant to any of the Agreements. 






 6. Under the circumstances contemplated by the Purchase Agreement, the offer, issuance and sale of the
Shares to the Investors are exempt from the registration requirements of Section 5 of the Securities Act. 
 7. The Company is not an
“investment company” as such term is defined in the Investment Company Act of 1940, as amended. 
 We express no opinion as to
(i) the past, present or future fair market value of any securities, (ii) compliance with the anti-fraud or other disclosure provisions of applicable securities law, if any, (iii) the enforceability under certain circumstances of any
provisions prohibiting waivers of any terms of the Agreements other than in writing, or prohibiting oral modifications thereof or modification by course of dealing or (iv) compliance by the Purchasers, as individuals or as a group, with any
Federal or state law relating to the legal or regulatory status of the Purchasers, as individuals or as a group, or the nature of each Purchaser’s business. 
 We express no opinion herein as to laws other than the law of the State of New York, the General Corporation Law of the State of Delaware and the federal securities law of the United States of America. As you know, we
are not licensed to practice law in the State of Delaware and our opinions herein as to such law are based solely on our review of a standard compilation of the General Corporation Law of the State of Delaware. We express no opinion as to whether
the laws of any particular jurisdiction apply and no opinion to the extent that the laws of any jurisdiction other than those identified above are applicable to the Agreements or the transactions contemplated thereby. With respect to our opinion in
paragraph 5 as to laws applicable to the Company, we have not conducted any special investigation as to laws and our opinion with respect thereto is limited to the laws of the State of New York and United States Federal securities laws as in our
experience are normally applicable to transactions of the type contemplated by the Agreements. 
 All opinions herein are rendered as of the
time immediately preceding Closing unless otherwise indicated. 
 Our opinion that any Agreement is valid, binding or enforceable in
accordance with its terms is qualified as to: 
  

	(a)	limitations imposed by bankruptcy, insolvency, reorganization, arrangement, fraudulent conveyance, moratorium, or other laws relating to or affecting the rights of creditors
generally; 

  

	(b)	general principles of equity, including without limitation concepts of materiality, reasonableness, good faith and fair dealing, and the possible unavailability of specific
performance or injunctive relief, regardless of whether such enforceability is considered in a proceeding in equity or at law; 

  

	(c)	rights to indemnification or contribution, the enforceability of which may be limited by applicable law or equitable principles; and 

  

	(d)	provisions relating to choice of law, submission to jurisdiction, waiver of foreum nonconveniens or service of process. 

 This opinion letter is solely for your benefit in connection with the transaction described in the first paragraph of this opinion letter and may not be
relied upon, used or quoted for any other 







 
purpose, nor may it be referred to by, nor may copies hereof be delivered to, any other person, firm or entity without our prior written consent. We disclaim
obligation to update this opinion letter for events occurring or coming to our attention after the date hereof.

 Re: AtriCure, Inc. 
 Ladies and Gentlemen:

 AtriCure, Inc., a Delaware corporation (the “Company”), is writing with respect to a Securities Purchase Agreement, dated
as of May 24, 2007, entered into by and among the Company and the buyers named therein (collectively, the “Purchasers”) pursuant to which the Company issued to the Purchasers shares of the Company’s common stock, $0.001
par value per share (the “Common Stock”). Pursuant to that certain Registration Rights Agreement of even date, the Company agreed to register the resale of the Common Stock (collectively, the “Registrable
Securities”), under the Securities Act of 1933, as amended (the “Securities Act”). In connection with the Company’s obligations under the Registration Rights Agreement, on ,
                    ,          the Company filed a Registration Statement on Form S-3 (File
No. 333-                      ) (the “Registration Statement”) with the Securities and Exchange Commission (the
“Commission”) relating to the Registrable Securities which names each of the Purchasers as a selling shareholder thereunder. 
 In connection with the foregoing, we advise you that a member of the Commission’s staff has advised us by telephone that the Commission has entered an order declaring the Registration Statement effective under the Securities Act at
         [a.m.][p.m.] on                     ,
        , and we have no knowledge, after telephonic inquiry of a member of the staff, that any stop order suspending its effectiveness has been issued or that any proceedings for that purpose are
pending before, or threatened by, the Commission and the Registrable Securities are available for resale under the Securities Act pursuant to the Registration Statement. 
 This letter shall serve as our standing notice to you that the Common Stock may be freely transferred by the Purchasers pursuant to the Registration Statement. You need not require further letters from us to effect
any future legend-free issuance or reissuance of shares of Common Stock to the Purchasers or the transferees of the Purchasers, as the case may be, as contemplated by the Company’s Irrevocable Transfer Agent Instructions dated
                    , 2007, provided at the time of such reissuance, the Company has not otherwise notified you that the Registration
Statement is unavailable for the resale of the Registrable Securities. This letter shall serve as our standing instructions with regard to this matter.
