 EXHIBIT 4.1.1 
  
 ATRICURE, INC. 
  
 AMENDMENT NO. 1 TO 
  
 AMENDED AND RESTATED INVESTORS’ RIGHTS AGREEMENT 
  
 THIS AMENDMENT NO. 1 is
made as of March 8, 2005, between ATRICURE, Inc., a Delaware corporation (the “Company”), and the Investors set forth on the signature pages hereto. 
  
 The [Company and the Investors] are parties to that certain [Amended and
Restated Investors’ Rights Agreement], dated as of June 6, 2002 (the “Investors’ Agreement”). In connection with a working capital credit facility with Lighthouse Capital Partners V, L.P. (“Lighthouse”),
the Company will issue a warrant to Lighthouse (the “ Warrant”) to acquire shares of the Company’s Common Stock (the “Common Stock”). 
  
 As a condition to the financing, the Company has agreed to grant Lighthouse registration rights with respect to the shares
of the Company’s Common Stock, and the Investors desire to amend the Investors’ Agreement to include Lighthouse thereunder. 
  
 NOW, THEREFORE, in consideration of the mutual covenants contained herein and other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
  
 1. The Company and the Investors hereby amend the Investors’ Agreement to include Lighthouse as a “Holder” and an
“Investor” thereunder and to include the Common Stock issuable upon exercise of the Warrant as “Registrable Securities” thereunder. 
  
 2. The definitions of “Holder”, “Investor” and “Registrable Securities” set forth in Section 2.1 of the
Investors’ Agreement shall be amended in their entirety as set forth below: 
  
 (d) “Holder” shall mean any Investor holding Registrable Securities or securities convertible into Registrable Securities
and any person holding such securities to whom the rights under this Section 2 have been transferred in accordance with Section 2.11 hereof, and shall include, without limitation, Lighthouse Capital Partners V, L.P. (“Lighthouse”).

  
 (f) “Investor” means either
an Investor who has signed this Agreement or a Holder and shall include, without limitation, Lighthouse Capital Partners V, L.P. (“Lighthouse”). 
  
 (i) “Registrable Securities” means (i) the Series A Preferred Stock, (ii) the Series B Preferred Stock, (iii) any Common
Stock issuable upon conversion of the Series A Preferred Stock or the Series B Preferred Stock (“Conversion Stock”), (iv) any Common Stock of the Company issued or issuable with respect to, or in exchange for or in replacement of, the
Conversion Stock or other securities convertible into or exercisable for Series A Preferred Stock or Series B Preferred Sock upon any stock split, stock dividend, recapitalization, or similar event, and (v) all shares of Common Stock of the Company
now or hereafter held by Lighthouse Capital Partners V, L.P. (“Lighthouse”), including, without limitation, the shares of Common Stock issued or issuable upon exercise of the warrants to purchase Common Stock held by Lighthouse; provided,
however, that shares of Common Stock or other securities shall only be treated as Registrable Securities for the purposes of Sections 2.2, 2.3 and 2.4 hereof (A) if and so long as they have not been sold to or through a broker or dealer or
underwriter in a public distribution or a public securities transaction or (B) prior to the date such securities have been sold in a transaction exempt from the prospectus delivery requirements of the Securities Act so that all transfer restrictions
and legends with respect thereto are removed upon consummation of such sale. 
  
 3. The following new definition is added to Section 2.1 of the Investors Agreement: 
  
 (q) “Lighthouse” means Lighthouse Capital Partners V, L. P. 
  
 4. Each Major Investor,, by executing this Amendment No. 1, hereby
agrees to waive its right of first refusal (and any related or corresponding notice requirement) contained in Section 3 of the Investors’ Agreement to purchase any of the Common Stock, or any warrants to purchase Common Stock,
issued or to be issued to Lighthouse pursuant to the Warrant, or any Common Stock in connection with the issuance of Common Stock to Lighthouse pursuant to the Warrant. 

 5. For purposes of the Investors’ Agreement, Lighthouse and any other holder of the Warrant
and the Common Stock issuable upon exercise thereof shall be deemed to be the record holder or holders of the Registrable Securities issuable directly or indirectly upon exercise and conversion thereof. 
  
 6. All notices and other communications under the Investors’
Agreement shall be made to Lighthouse at the address specified below and thereafter at such other address, notice of which is given in accordance with Section 5.3 of the Investors’ Agreement:

ATRICURE, INC. 
  
 AMENDED AND RESTATED RIGHT OF FIRST REFUSAL 
 AND CO-SALE AGREEMENT 
  
 JUNE 6, 2002

  

  
 EXECUTION COPY

  
 ATRICURE, INC. 
  
 AMENDED AND RESTATED RIGHT OF FIRST REFUSAL 
 AND CO-SALE AGREEMENT 
  
 THIS AMENDED AND RESTATED RIGHT OF FIRST
REFUSAL AND CO-SALE AGREEMENT (this “Agreement”) is made as of this 6th day of June, 2002, by and among ATRICURE, INC., a Delaware corporation (the “Company”), the holders of the Company’s Series A Convertible
Preferred Stock (the “Series A Stock”) and Series B Convertible Preferred Stock (the “Series B Stock”) listed on Exhibit A hereto (collectively, the “Investors”), the founding common stockholders of the Company
listed on Exhibit B attached hereto (each a “Founder,” and collectively, the “Founders”), and the other holders of Common Stock listed on the signature pages to this Agreement (such stockholders, along with the Investors
and the Founders, collectively, the “Stockholders”). 
  
 RECITALS 
  
 WHEREAS, the Company proposes to sell and issue shares of its Series B Stock pursuant to the Series B Convertible Preferred Stock Purchase Agreement of the same date herewith (the “Purchase
Agreement”); and 
  
 WHEREAS, as an inducement for the purchase of the Series B Stock by certain of the Investors, the Company and the Stockholders have agreed to enter into this Agreement (which agreement amends and
restates the Right of First Refusal and Co-Sale Agreement, dated as of May 25, 2001, among the Company, the holders of the Company’s Series A Stock and the Founders (the “Original Agreement”)) and to grant those Investors purchasing
Series B Stock certain right of first refusal and co-sale rights. 
  
 NOW, THEREFORE, in consideration of the mutual promises, representations, warranties, covenants and conditions set forth in this Agreement and in the Purchase Agreement, the parties
mutually agree as follows: 
  

	1.	DEFINITIONS. 

  
 (a) “Capital Stock” shall mean shares of Preferred Stock and Common Stock. 
  
 (b) “Common Stock” shall mean the Company’s
Common Stock (including shares of Common Stock issued upon conversion of the Preferred Stock) and shares of Common Stock issuable upon the exercise of any option, warrant or other security or right of any kind convertible into or exchangeable for
Common Stock (other than the Preferred Stock). 
  
 (c)
“Co-Sale Stock” shall mean shares of the Company’s Common Stock now owned or subsequently acquired by a Founder, whether or not such securities are registered in such Founder’s name or beneficially or otherwise legally
owned by such Founder, including any interest of such Founder’s spouse or immediate family members (or any trust created for the 

  

 
benefit of any of them) in shares of the Company’s Common Stock, whether that interest is asserted pursuant to marital property laws or otherwise. The
number of shares of Co-Sale Stock owned by a Founder (including shares owned by such Founder’s spouse or immediate family members (or any trust created for the benefit of any of them)) as of the date hereof are set forth on Exhibit B,
which Exhibit may be amended from time to time by the Company to reflect changes in the number of shares of Co-Sale Stock owned by a Founder (or his spouse, immediate family member or trust), but the failure to so amend shall have no effect on such
Co-Sale Stock being subject to this Agreement. 
  
 (d)
“Investor Stock” shall mean shares of Preferred Stock and shares of Common Stock issued upon conversion of the Preferred Stock. 
  
 (e) “Preferred Stock” shall mean shares of Series A Stock of the Company and/or Series B Stock held by the Investors and listed opposite
such Investor’s name on Exhibit A hereto. Exhibit A may be amended from time to time by the Company to reflect changes in the number of shares of Preferred Stock held by any Investor (or by any new Investor), but the failure to so
amend shall have no effect on any rights of any Investor under this Agreement. 
  
 (f) For the purpose of this Agreement, the term “Transfer” shall include any sale, assignment, encumbrance, hypothecation, pledge, conveyance in trust, gift, transfer by request, devise or
descent, or other transfer or disposition of any kind, including, but not limited to, transfers to receivers, levying creditors, trustees or receivers in bankruptcy proceedings or general assignees for the benefit of creditors, whether voluntary or
by operation of law, directly or indirectly, of any of the Co-Sale Stock. 
  

	2.	TRANSFERS BY A FOUNDER. 

  

(a) Notice of Transfer. If a Founder proposes to Transfer any shares of Co-Sale Stock, then the Founder shall promptly give written notice (the
“Transfer Notice”) simultaneously to the Company and to each of the Investors at least thirty (30) days prior to the closing of such Transfer. The Transfer Notice shall describe in reasonable detail the proposed Transfer including, without
limitation, the number of shares of Co-Sale Stock to be transferred, the nature of such Transfer, the consideration to be paid, and the name and address of each prospective purchaser or transferee. In the event that the Transfer is being made
pursuant to the provisions of Section 3(a) hereof, the Transfer Notice shall state under which subsection thereof the Transfer is being made. 
  
 (b) Right of First Refusal. The Company shall have a right of first refusal to purchase any and all Co-Sale Stock that a Founder proposes to
Transfer. Subject to the exercise of this right of first refusal by the Company, the Investors shall have the right to purchase all of the Co-Sale Stock not repurchased by the Company (the “Right of First Refusal”). The Company shall
within five (5) days after receipt of the Transfer Notice give written notice to the Founder and the Investors of the number of shares of Co-Sale Stock the Company intends to repurchase. 
  
 (i) Each Investor’s Right of First Refusal shall be to purchase its pro rata share of the
balance of Co-Sale Stock to be Transferred by the Founder as specified in the 

  

 2 

 
Transfer Notice remaining after the Company exercises its right of first refusal. An Investor may exercise its right by giving written notice (the “Buy
Notice”) to the Founder, with a copy to the Company, within fifteen (15) days after its receipt of the Transfer Notice, specifying the maximum number of shares of Co-Sale Stock such Investor wishes to buy under its Right of First Refusal. Each
Investor who so elects to buy part of the Co-Sale Stock to be Transferred shall hereinafter be referred to as a “Buyer.” 
  
 (ii) If the total number of shares specified in all such Buy Notices exceeds the number of shares of Co-Sale Stock referred to in
said Transfer Notice, each Buyer shall be entitled to purchase such portion of the Co-Sale Stock to be Transferred as the number of shares of Investor Stock owned by it bears to the total number of shares of Investor Stock owned by all Buyers. If
all of the Co-Sale Stock to be Transferred is not allocated under such apportionment, each Buyer whose Buy Notice specified a number of shares in excess of its proportionate share, as provided above, shall be entitled to purchase such proportion of
those shares which remain thus unallocated as the total number of shares of Investor Stock which it owns bears to the total number of shares of Investor Stock owned by all Buyers desiring to purchase excess shares. Such apportionment shall be made
successively until all of the shares of Co-Sale Stock to be Transferred have been allocated to Buyers up to the aggregate number of shares specified in all Buy Notices. Notwithstanding the foregoing, all apportionments required by this subsection
(ii) must be made within five (5) days after the Founder’s receipt of the Buy Notice. 
  
 (iii) To the extent there are shares of Co-Sale Stock to be Transferred remaining after the allocations of subsection (ii) above,
the Founder may, subject to the right of co-sale specified in Subsection (d) below, Transfer them to the prospective purchaser or transferee specified in the Transfer Notice. 
  
 (c) First Refusal Closing. The Founder shall notify the Company and the Buyers as soon as practicable of the closing
of the Transfer of the Co-Sale Stock to the Company and/or the Buyers (the “First Refusal Closing”). At the First Refusal Closing, such certificates or other instruments will be delivered, duly endorsed for transfer, free and clear of all
liens and encumbrances, to the Company and/or the Buyers, and the Company and/or the Buyers will remit to the Founder the consideration per share of Co-Sale Stock as contained in the Transfer Notice. 
  
 (d) Right of Co-Sale. Subject to exercise of any right of first
refusal in favor of the Company or the Investors, each Investor shall have the right, exercisable upon written notice (“Co-Sale Notice”) to such Founder within fifteen (15) days after the Transfer Notice, to participate in such Transfer of
Co-Sale Stock on the same terms and conditions. Each Investor who so elects to participate in the Transfer pursuant to this Subsection (d) shall hereinafter be referred to as a “Participant.” Such Co-Sale Notice shall indicate the number
of shares of Common Stock that such Participant wishes to sell under his or her right to participate. To the extent one or more of the Investors exercise such right of participation in accordance with the terms and conditions set forth below, the
number of shares of Co-Sale Stock that such Founder may sell in the transaction shall be correspondingly reduced. 
  
 (i) Each Participant may sell all or any part of that number of shares equal to the product obtained by multiplying (i) the
aggregate balance of shares of Co-Sale Stock covered 

  

 3 

 
by the Transfer Notice remaining after exercise of the Company’s and the Investors’ Rights of First Refusal by (ii) a fraction, the numerator of
which is the number of shares of Investor Stock owned by such Participant at the time of the Transfer, and the denominator of which is the total number of shares of Investor Stock owned by such Founder and all the Investors at the time of the
Transfer. 
  
 (ii) Each Participant shall
effect its participation in the Transfer by promptly delivering to such Founder for transfer to the prospective purchaser one or more certificates, properly endorsed for transfer, which represent: 
  

	 	(1)	the type and number of shares of Common Stock which such Participant elects to sell; or 

  

	 	(2)	that number of shares of Preferred Stock which is at such time convertible into the number of shares of Common Stock which such Participant elects to sell; provided,
however, that if the prospective purchaser objects to the delivery of Preferred Stock in lieu of Common Stock, such Participant shall convert such Preferred Stock into Common Stock and deliver Common Stock as provided in Section 2(d)(ii)(1)
above. The Company agrees to make any such conversion concurrent with the actual transfer of such shares to the prospective purchaser. 

  
 (iii) The stock certificate or certificates that the Participant delivers to such Founder pursuant to Section 2(d)(ii) above shall
be transferred to the prospective purchaser in consummation of the sale of the Common Stock pursuant to the terms and conditions specified in the Transfer Notice, and the Founder shall concurrently therewith remit to such Participant that portion of
the sale proceeds to which such Participant is entitled by reason of its participation in such sale. To the extent that any prospective purchaser or purchasers prohibits such assignment or otherwise refuses to purchase shares or other securities
from a Participant exercising its rights of co-sale hereunder, such Founder shall not sell to such prospective purchaser or purchasers any Co-Sale Stock unless and until, simultaneously with such sale, such Founder shall purchase such shares or
other securities from such Participant on the same terms and conditions specified in the Transfer Notice. 
  
 (e) The exercise or non-exercise of the rights of the Investors hereunder to participate in one or more Transfers of Co-Sale Stock made by such
Founder shall not adversely affect their rights to participate in subsequent Transfers of Co-Sale Stock. 
  
 (f) The Founder shall have sixty (60) days after the giving of the Transfer Notice to Transfer the shares of Co-Sale Stock specified in the
Transfer Notice as to which neither the rights of first refusal nor the co-sale rights set forth in this Agreement have been exercised, at the price and upon terms and conditions not materially more beneficial to the Founder than specified in the
Transfer Notice. If the Founder has not Transferred said shares of Co-Sale Stock within said 60 days, the Founder shall not thereafter Transfer any shares of Co-Sale Stock without first giving a new Transfer Notice and otherwise fully complying with
the terms and conditions of this Agreement. 
  

 4 

	3.	EXEMPT TRANSFERS. 

  
 (a) Notwithstanding the foregoing, the rights of first refusal and co-sale rights of the Company and the Investors shall not apply to (i) any
transfer or transfers by a Founder which in the aggregate, over the term of this Agreement, amount to no more than five percent (5%) of the shares of Co-Sale Stock held by the Founder as of June 6, 2002 (as adjusted for stock splits, dividends and
the like), (ii) any transfer to the ancestors, descendants or spouse or to trusts for the benefit of such persons or the Founder, (iii) any transfer or transfers by a Founder to another Founder (the “Transferee-Founder”) so long as the
Transferee-Founder is, at the time of the transfer, employed by or acting as a consultant, officer or director of the Company, (iv) any pledge of Co-Sale Stock made pursuant to a bona fide loan transaction with a financial institution that creates a
mere security interest, or (v) any bona fide gift; provided that in the event of any transfer made pursuant to one of the exemptions provided by clauses (ii), (iii), (iv) and (v), (A) the Founder shall inform the Company and the
Investors of such pledge, transfer or gift prior to effecting it and (B) the pledgee, transferee or donee shall furnish the Company and the Investors with a written agreement to be bound by and comply with all provisions of this Agreement. Except
with respect to Co-Sale Stock transferred under clause (i) above (which Co-Sale Stock shall no longer be subject to the rights of first refusal and co-sale rights of the Company and the Investors), such transferred Co-Sale Stock shall remain
“Co-Sale Stock” hereunder, and such pledgee, transferee or donee shall be treated as a “Founder” for purposes of this Agreement. 
  
 (b) The provisions of Section 2 hereof shall not apply to the sale of any Co-Sale Stock to the Company or to the public pursuant to a registration
statement filed with, and declared effective by, the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). 
  
 (c) This Agreement is subject to, and shall in no manner limit the right which the Company may have to repurchase
securities from the Founder pursuant to (i) a stock restriction agreement or other agreement between the Company and the Founder and (ii) any right of first refusal set forth in the Bylaws of the Company. 
  

	4.	PROHIBITED TRANSFERS. 

  
 (a) In the event that a Founder should Transfer any Co-Sale Stock in contravention of the rights of first refusal or co-sale rights under this
Agreement (a “Prohibited Transfer”), each Investor, in addition to such other remedies as may be available at law, in equity or hereunder, shall have the put option provided below, and such Founder shall be bound by the applicable
provisions of such option. 
  
 (b) In the event of a
Prohibited Transfer, each Investor shall have the right to sell to such Founder the type and number of shares of Common Stock equal to the number of shares each Investor would have been entitled to transfer to the purchaser under Section 2(d) hereof
had the Prohibited Transfer been effected pursuant to and in compliance with the terms hereof. Such sale shall be made on the following terms and conditions: 
  

	 	(i)	 The price per share at which the shares are to be sold to the Founder shall be equal to the price per share paid by the purchaser to such Founder in 

  

 5 

	 	 
such Prohibited Transfer. The Founder shall also reimburse each Investor for any and all fees and expenses, including legal fees and expenses, incurred
pursuant to the exercise or the attempted exercise of the Investor’s rights under Section 2 hereof: 

  

	 	(ii)	Within ninety (90) days after the date on which an Investor received notice of the Prohibited Transfer or otherwise became aware of the Prohibited Transfer, such Investor
shall, if exercising the option created hereby, deliver to the Company’s general legal counsel the certificate or certificates representing shares to be sold, each certificate to be properly endorsed for transfer. The Company’s general
legal counsel shall promptly notify the Founder of the exercise of the put option. 

  

	 	(iii)	Such Founder shall, within thirty (30) days after receipt of notice from the Company’s general legal counsel that an Investor has exercised its put option, deliver to
the Company’s general legal counsel the aggregate purchase price therefor and the amount of reimbursable fees and expenses, as specified in Section 4(b)(i) above, in cash or by other means acceptable to the Investor. 

 

	 	(iv)	Upon receipt of the aggregate purchase price and reimbursable fees and expenses specified in subsection (iii) above, the Company’s general legal counsel shall deliver
the same to the Investor who had exercised its put option. The Company’s general legal counsel shall then cause the certificate(s) to be transferred into the name of the Founder and shall deliver the same to the Founder with the legends
specified in Section 6(a) below. 

  

	 	(v)	Notwithstanding the foregoing, any attempt by a Founder to transfer Co-Sale Stock in violation of Section 2 hereof shall be voidable at the option of a majority in interest
of the Investors if such Investors do not elect to exercise the put option set forth in this Section 4, and the Company agrees it will not effect such a transfer nor will it treat any alleged transferee as the holder of such shares without the
written consent of a majority in interest of the Investors. 

  

	5.	TAKE-ALONG RIGHTS. 

  
 (a) If any person or entity offers to acquire all or substantially all of the assets or business of the Company, by merger, sale of assets, stock
purchase or otherwise, and the holders of (i) 66 2/3% in interest of the then outstanding shares of Series A Stock, (ii) 66 2/3% in interest of the then outstanding shares of Series B Stock and (iii) a majority in interest of the then outstanding
shares of Common Stock, voting separately, have voted in favor of such transaction (whether at an annual or special meeting of stockholders or by written consent in lieu of a meeting of stockholders) (an “Approved Sale”), then all
remaining holders of Series A Stock, Series B Stock and Common Stock shall be obligated to (a) vote all of their shares of Capital Stock (the “Shares”) in favor of the transaction, (b) sell, transfer or exchange all of their Shares 

  

 6 

 
in connection with such transaction on the same terms as those consented to by such consenting holders of the Company’s voting Capital Stock (with
appropriate adjustment to reflect the conversion of convertible securities and the preference and priorities of the Company’s Preferred Stock), and (c) execute and deliver such instruments of conveyance and transfer and take such other actions,
including executing any purchase agreement, merger agreement, indemnity agreement, escrow agreement or related documents, as may be reasonably required by the Company in order to carry out the terms and provision of this Section 5. 
  
 (b) If the Approved Sale is structured as a merger or consolidation,
all holders of Series A Stock, Series B Stock and Common Stock (each an “Obligee”) shall waive any dissenters’ rights, appraisal rights or similar rights in connection with the Approved Sale. If an Obligee fails or refuses to vote or
sell his, her or its Shares as required by, or votes its Shares in contravention of, this Section 5, then each such Obligee hereby grants to the Company’s then Chief Executive Officer an irrevocable proxy, coupled with an interest, to vote such
Shares in accordance with this Section 5, and hereby appoints such officer its attorney in fact, to sell such Shares in accordance with the terms of this Section 5. At the closing of such transaction, each Obligee shall deliver, against receipt of
the consideration payable in such transaction, certificates representing the Shares which such Obligee holds of record or beneficially, with all endorsements necessary for transfer. In the event that an Obligee fails or refuses to comply with the
provisions of this Section 5, the Company, the Stockholders and the purchaser in such transaction, at their option, may elect to proceed with such transaction notwithstanding such failure or refusal and, in such event and upon tender of the
specified consideration to any Obligee, the rights of any such Obligee with respect to the Shares of such Obligee shall cease. 
  

	6.	LEGEND. 

  
 (a) Each certificate representing shares of Co-Sale Stock now or hereafter owned by a Founder or issued to any person in connection with a transfer
pursuant to Section 3(a) hereof shall be endorsed with the following legend: 
  
 THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT BY AND BETWEEN THE
INVESTOR, THE COMPANY AND CERTAIN HOLDERS OF STOCK OF THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY. 
  
 Each Founder agrees to submit promptly to the Company all certificates evidencing any shares of Co-Sale Stock owned by him/her/it of record
or beneficially, directly or indirectly, in order that the Company may endorse the foregoing legend on such certificates. The Company agrees to endorse the foregoing legend on all certificates evidencing any shares of Co-Sale Stock whether now
outstanding or issued hereafter. 
  
 (b) Each Founder
agrees that the Company may instruct its transfer agent to impose transfer restrictions on the shares represented by certificates bearing the legend referred to in 

  

 7 

 
Section 6(a) above to enforce the provisions of this Agreement and the Company agrees to promptly do so. The legend shall be removed upon termination of this
Agreement. 
  

	7.	MISCELLANEOUS. 

  
 (a) Conditions to Exercise of Rights. Exercise of the Investors’ rights under this Agreement shall be subject to and conditioned upon, and the
Founders and the Company shall use their best efforts to assist each Investor in, compliance with applicable laws. 
  
 (b) Governing Law. This Agreement shall be governed by and construed under the laws of the State of New York without regard to its conflicts
of laws principles. 
  
 (c) Amendment and Waiver.
Any provision of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively) only by the written consent of (i) the Company, (ii) the holders of
a majority of the Common Stock then held by Founders, (iii) the holders of at least sixty-six and two-thirds percent (66-2/3%) of the Series A Stock then held by Investors and their permitted assignees pursuant to Section 7(d) below, and (iv) the
holders of at least a majority of the Series B Stock then held by Investors and their permitted assignees pursuant to Section 7(d) below. Any amendment or waiver effected in accordance with this Section 7(c) shall be binding upon the Company and all
of the Stockholders; provided that no amendment or waiver of this Agreement shall materially and adversely affect the rights of a party in a manner that discriminates against such party vis-à-vis other parties in the same class without such
party’s written consent. Notwithstanding the foregoing, this Agreement may be amended with only the written consent of the Company to include additional purchasers of Series B Stock as “Investors” and parties hereto. 
  
 (d) Successors and Assigns. This Agreement and the rights and
obligations of the parties hereunder shall inure to the benefit of, and be binding upon, their respective successors, assigns and legal representatives. 
  
 (e) Term. This Agreement shall terminate upon the earlier of (i) the consummation of a Qualified Public Offering (as defined in Article IV, Section
2(b)(i) of the Company’s Certificate of Incorporation), or (ii) the acquisition of all, or substantially all, of the Company’s assets or business, by asset sale, merger, consolidation or otherwise. 
  
 (f) Ownership. Each Founder represents and warrants that he/she
is the sole legal and beneficial owner of those shares of Co-Sale Stock he/she currently holds subject to this Agreement and that no other person or entity has any interest (other than a community property interest) in such shares. 
  
 (g) Notices. All notices required or permitted hereunder shall be in
writing and shall be deemed effectively given: (i) upon personal delivery to the party to be notified, (ii) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient; if not, then on the next business day, (iii)
five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (iv) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery. All communications shall
be sent to 

  

 8 

 
the party to be notified at the address set forth on the Company’s records or at such other address as such party may designate by ten (10) days advance
written notice to the other parties hereto. 
  
 (h)
Severability. If any provision of this Agreement is held to be unenforceable under applicable law, it shall be interpreted, to the extent possible, to enhance its enforceability in order to achieve the intent of the parties to this Agreement.
But if no feasible construction would save the provision, the parties agree to renegotiate such provision in good faith. In the event the parties cannot reach a mutually agreeable and enforceable replacement for such provision, its invalidity,
illegality or unenforceability shall not affect any other provision of this Agreement; rather this Agreement shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein; provided, however, no such
severability shall be effective if it materially changes the economic benefit of this Agreement to any party. The invalidity of any provision of this Agreement as applied to certain circumstances shall not affect the validity or enforceability of
such provision as applied to other circumstances or any other provisions of this Agreement. 
  
 (i) Attorneys’ Fees. In the event that any dispute among the parties to this Agreement should result in litigation or arbitration, the prevailing party in such dispute shall be entitled to recover from the
losing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect to this Agreement, including without limitation, such reasonable fees and expenses of attorneys and accountants, which shall include,
without limitation, all fees, costs and expenses of appeals. 
  
 (j) Entire Agreement. This Agreement and the Exhibits hereto, along with the Purchase Agreement and each of the Exhibits thereto and all agreements, certificates and documents delivered thereunder, constitute the full and entire
understanding and agreement between the parties with regard to the subjects hereof and thereof and no party shall be liable or bound to any other in any manner by any representations, warranties, covenants and agreements except as specifically set
forth herein and therein. This Agreement supercedes all prior agreements and undertakings, written (including, without limitation, the Original Agreement) and oral, with respect to the subject matter hereof. 
  
 (k) Counterparts. This Agreement may be executed by facsimile
signatures and in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 
  

(l) Further Assurances. Each of the parties hereto shall execute and deliver such instruments and take such other actions as the other parties
may reasonably request in order to carry out the intent of this Agreement. 
  
 (m) Rights of Investors. Each Investor shall have the absolute right to exercise or refrain from exercising any right or rights that such Investor may have by reason of this Agreement including, without
limitation, the right to consent to any wavier or amendment of this Agreement. Each such Investor shall not incur any liability to any other Investor with respect to exercising or refraining from exercising any such right or rights. 
  

 9 

 (n) Assignment of Rights. The rights of first refusal and the co-sale rights granted by this
Agreement may be assigned by an Investor only to a transferee or assignee of shares of Investor Stock which (a) is a general partner, limited partner, retired partner, member or retired member of the Investor, or (b) is an affiliate of the Investor,
or (c) is the Investor’s family member or a trust for the benefit of an individual Investor or family member, or (d) acquires at least 250,000 shares of the stock (as appropriately adjusted for stock splits and the like); provided, however, (i)
the assigning Investor shall have furnished to the Company and all other parties to this Agreement written notice of the name and address of such transferee or assignee and the securities with respect to which such rights are being assigned, and
(ii) such transferee shall agree to be subject to all restrictions on Investors set forth in this Agreement. An “affiliate” of an Investor is a person directly or indirectly (through one or more intermediaries) controlling, controlled by,
or under common control with, that Investor. 
  
 (o) Delays or
Omissions. No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power or remedy of such
non-breaching or non-defaulting party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor shall any waiver of any single breach or
default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on
the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded
to any party, shall be cumulative and not alternative. 
  
 (p)
Construction and Titles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement. A reference herein to any Section shall be deemed to include a
reference to every subsection thereof. All pronouns contained herein, and any variations thereof, shall be deemed to refer to the masculine, feminine or neuter, singular or plural, as to the identity of the parties hereto may require.
