Exhibit 10.2

EXPORT-IMPORT BANK JOINDER AND THIRD LOAN MODIFICATION AGREEMENT

This Export-Import Bank Joinder and Third Loan Modification Agreement (this “Loan Modification Agreement”) is entered into and effective as of January 30, 2013 (the “Third Loan Modification Effective Date”), by and between (i) SILICON VALLEY BANK, a California corporation, with its principal place of business at 3003 Tasman Drive, Santa Clara, California 95054 and with a loan production office located at 380 Interlocken Crescent, Suite 600, Broomfield, Colorado 80021 (“Bank”), (ii) ATRICURE, INC., a Delaware corporation with its chief executive office located at 6217 Centre Park Drive, West Chester, Ohio 45069 (“Borrower”), and ATRICURE, LLC, a Delaware limited liability company (“New Borrower”).

1. DESCRIPTION OF EXISTING INDEBTEDNESS AND OBLIGATIONS. Among other indebtedness and obligations which may be owing by Borrower to Bank, Borrower is indebted to Bank pursuant to a loan arrangement dated as of September 13, 2010, evidenced by, among other documents, a certain Export-Import Bank Loan and Security Agreement, dated as of September 13, 2010, between Borrower and Bank, as amended by a certain Export-Import Bank First Loan Modification Agreement, dated as of March 15, 2011, and as amended by a certain Export-Import Bank Second Loan Modification Agreement, dated as of February 2, 2012 (as amended, the “Existing Loan Agreement”). Capitalized terms used but not otherwise defined herein shall have the same meaning as in the Loan Agreement.

2. DESCRIPTION OF COLLATERAL. Repayment of the Obligations is secured by the Collateral as described (i) in the Loan Agreement; (ii) in a certain Amended and Restated Loan and Security Agreement, dated as of September 13, 2010 (as amended and in effect as of the date hereof, the “Domestic Loan Agreement”); and (iii) in a certain Intellectual Property Security Agreement dated as of May 1, 2009 (the “IP Agreement”, and together with any other collateral security granted to Bank, the “Security Documents”).

Hereinafter, the Security Documents, together with the Existing Loan Agreement and all other documents evidencing or securing the Obligations shall be referred to as the “Existing Loan Documents”.

3. JOINDER AND ASSUMPTION. New Borrower is a wholly owned Subsidiary of Borrower. New Borrower hereby joins the Existing Loan Agreement and each of the other appropriate Existing Loan Documents, and agrees to comply with and be bound by all of the terms, conditions and covenants of the Existing Loan Agreement and each of the other appropriate Existing Loan Documents, as if New Borrower were originally named a “Borrower” and/or a “Debtor” therein. Without limiting the generality of the preceding sentence, New Borrower hereby assumes and agrees to pay and perform when due all present and future indebtedness, liabilities and obligations of Borrower under the Existing Loan Agreement, including, without limitation, the Obligations. From and after the date hereof, all references in the Existing Loan Documents to “Borrower” and/or “Debtor” shall be deemed to refer to and include New Borrower. Further, all present and future Obligations of Borrower shall be deemed to refer to all present and future Obligations of New Borrower. New Borrower acknowledges that the Obligations are due and owing to Bank from Borrower including, without limitation, New Borrower, without any defense, offset or counterclaim of any kind or nature whatsoever as of the date hereof.

4. GRANT OF SECURITY INTEREST. To secure the payment and performance of all of the Obligations, New Borrower hereby grants to Bank a continuing lien upon and security interest in all of New Borrower’s now existing or hereafter arising rights and interest in the Collateral, whether now owned or existing or hereafter created, acquired, or arising, and wherever located, including, without limitation, all of New Borrower’s assets listed on Exhibit A attached hereto and all of New Borrower’s books and records relating to the foregoing and any and all claims, rights and interests in any of the above and all substitutions for, additions, attachments, accessories, accessions and improvements to and replacements, products, proceeds and insurance proceeds of any or all of the foregoing. New Borrower represents, warrants, and covenants that the security interest granted herein is and shall at all times continue to be a first priority perfected security interest in the Collateral (subject only to Permitted Liens that may have superior priority to Bank’s Lien under the Existing Loan Agreement). If New Borrower shall acquire a commercial tort claim, such New Borrower shall promptly notify Bank in a writing signed by such New Borrower of the general details thereof and grant to Bank in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to Bank.

New Borrower further covenants and agrees that by its execution hereof it shall provide all such information, complete all such forms, and take all such actions, and enter into all such agreements, in form and substance reasonably satisfactory to Bank that are reasonably deemed necessary by Bank in order to grant and continue a valid, first perfected security interest to Bank in the Collateral. New Borrower hereby authorizes Bank to file financing statements, without notice to any Borrower, with all appropriate jurisdictions in order to perfect or protect Bank’s interest or rights hereunder, including a notice that any disposition of the Collateral, by either any Borrower or any other Person, may be deemed to violate the rights of Bank under the Code. Such financing statements may indicate the Collateral as “all assets of the Debtor” or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in Bank’s discretion.

5. SUBROGATION AND SIMILAR RIGHTS. Borrower (in each case including, without limitation, New Borrower) waives any suretyship defenses available to it under the Code or any other applicable law. Borrower waives any right to require Bank to: (i) proceed against any other Borrower or any other Person; (ii) proceed against or exhaust any security; or (iii) pursue any other remedy. Bank may exercise or not exercise any right or remedy it has against any Borrower or any security it holds (including the right to foreclose by judicial or non-judicial sale) without affecting any Borrower’s liability. Notwithstanding any other provision of this Loan Modification Agreement, the Existing Loan Agreement, or any other Existing Loan Documents, Borrower irrevocably subordinates to the prior payment in full of the Obligations and the termination of the Bank’s commitment to make Credit Extensions to Borrower and agrees not to assert or enforce prior to the payment in full of the Obligations and the termination of the Bank’s commitment to make Credit Extensions to Borrower all rights that it may have at law or in equity (including, without limitation, any law subrogating such Borrower to the rights of Bank under the Existing Loan Agreement), to seek contribution, indemnification or any other form of reimbursement from any other Borrower or any other Person now or hereafter primarily or secondarily liable for any of the Obligations, for any payment made by a Borrower with respect to the Obligations in connection with the Existing Loan Agreement or otherwise and all rights that it might have to benefit from, or to participate in, any security for the Obligations as a result of any payment made by any Borrower with respect to the Obligations in connection with the Existing Loan Agreement or otherwise. If any payment is made to any Borrower in contravention of this section, such Borrower shall hold such payment in trust for Bank and such payment shall be promptly delivered to Bank for application to the Obligations, whether matured or unmatured. Either Borrower may, acting singly, request Credit Extensions under the Existing Loan Agreement. Each Borrower hereby appoints the other as agent for the other for all purposes under the Existing Loan Agreement, including with respect to requesting Credit Extensions thereunder. Each Borrower shall be jointly and severally obligated to repay all Credit Extensions made under the Existing Loan Agreement or any other Existing Loan Documents, regardless of which Borrower actually received said Credit Extension, as if each Borrower directly received all Credit Extensions.

6. REPRESENTATIONS AND WARRANTIES. Except as described in the revised Perfection Certificate delivered in connection herewith, Borrower hereby represents and warrants to Bank that all representations and warranties in the Existing Loan Documents made on the part of any Borrower are true and correct on the date hereof with respect to New Borrower, with the same force and effect as if New Borrower were originally named as “Borrower” in the Existing Loan Documents. In addition, Borrower and New Borrower hereby represent and warrant to Bank that this Loan Modification Agreement has been duly executed and delivered by Borrower and New Borrower, and constitutes their legal, valid and binding obligation, enforceable against each in accordance with its terms, except as may be limited by applicable bankruptcy or insolvency laws or laws affecting the rights of creditors generally or by principals of equity. Hereafter, each reference to “Borrower” and/or “Debtor”) in any Existing Loan Document shall be deemed to reference both Borrower and New Borrower.

7. DESCRIPTION OF CHANGE IN TERMS.

“Third Loan Modification Effective Date” is January 30, 2013.

8. CONDITIONS PRECEDENT. As a condition precedent to the effectiveness of this Loan Modification Agreement and the Bank’s obligation to make further EXIM Advances under the Revolving Line, the Bank shall have received the following documents prior to or concurrently with this Loan Modification Agreement, each in form and substance satisfactory to the Bank:

9. FEES. Borrower shall reimburse Bank for all legal fees and expenses incurred in connection with this Loan Modification Agreement.

10. AUTHORIZATION TO FILE. Borrower hereby authorizes Bank to file UCC financing statements without notice to Borrower, with all appropriate jurisdictions, as Bank deems appropriate, in order to further perfect or protect Bank’s interest in the Collateral, including a notice that any disposition of the Collateral, by either the Borrower or any other Person, shall be deemed to violate the rights of the Bank under the Code.

11. CONSISTENT CHANGES. The Existing Loan Documents are hereby amended wherever necessary to reflect the changes described above.

12. RATIFICATION OF LOAN DOCUMENTS. Borrower hereby ratifies, confirms, and reaffirms all terms and conditions of all security or other collateral granted to the Bank, and confirms that the indebtedness secured thereby includes, without limitation, the Obligations.

13. NO DEFENSES OF BORROWER. Borrower hereby acknowledges and agrees that Borrower has no offsets, defenses, claims, or counterclaims against Bank with respect to the Obligations, or otherwise, and that if Borrower now has, or ever did have, any offsets, defenses, claims, or counterclaims against Bank, whether known or unknown, at law or in equity, all of them are hereby expressly WAIVED and Borrower hereby RELEASES Bank from any liability thereunder.

14. CONTINUING VALIDITY. Borrower understands and agrees that in modifying the existing Obligations, Bank is relying upon Borrower’s representations, warranties, and agreements, as set forth in the Existing Loan Documents. Except as expressly modified pursuant to this Loan Modification Agreement, the terms of the Existing Loan Documents remain unchanged and in full force and effect. Bank’s agreement to modifications to the existing Obligations pursuant to this Loan Modification Agreement in no way shall obligate Bank to make any future modifications to the Obligations. Nothing in this Loan Modification Agreement shall constitute a satisfaction of the Obligations. It is the intention of Bank and Borrower to retain as liable parties all makers of Existing Loan Documents, unless the party is expressly released by Bank in writing. No maker will be released by virtue of this Loan Modification Agreement.

15. RIGHT OF SET-OFF. In consideration of Bank’s agreement to enter into this Loan Modification Agreement, Borrower hereby reaffirms and hereby grants to Bank, a lien, security interest and right of set off as security for all Obligations to Bank, whether now existing or hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Bank or any entity under the control of Silicon Valley Bank (including a Bank subsidiary) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Bank may set off the same or any part thereof and apply the same to any liability or obligation of Borrower even though unmatured and regardless of the adequacy of any other collateral securing the loan. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

16. CONFIDENTIALITY. Without limiting Section 12.10 of the Loan Agreement (which is and shall remain in full force and effect), Bank may use confidential information for the development of databases, reporting purposes, and market analysis, so long as such confidential information is aggregated and anonymized prior to distribution unless otherwise expressly permitted by Borrower. The provisions of the immediately preceding sentence shall survive the termination of the Loan Agreement.

JURISDICTION/VENUE. California law governs the Loan Documents, including, without limitation, this Loan Modification Agreement without regard to principles of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction of the State and Federal courts in Santa Clara County, California; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Bank from bringing suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Bank. Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Borrower hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in, or subsequently provided by Borrower in accordance with, Section 10 of the Loan Agreement and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid.

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS LOAN MODIFICATION AGREEMENT, THE LOAN AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

WITHOUT INTENDING IN ANY WAY TO LIMIT THE PARTIES’ AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies of any nature between them arising at any time shall be decided by a reference to a private judge, mutually selected by the parties (or, if they cannot agree, by the

4

Presiding Judge of the Santa Clara County, California Superior Court) appointed in accordance with California Code of Civil Procedure Section 638 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts), sitting without a jury, in Santa Clara County, California; and the parties hereby submit to the jurisdiction of such court. The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1, inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers. All such proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that point pursuant to the judicial reference procedures, then such party may apply to the Santa Clara County, California Superior Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial proceedings. The private judge shall oversee discovery and may enforce all discovery rules and orders applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this paragraph.

17. COUNTERSIGNATURE. This Loan Modification Agreement shall become effective only when it shall have been executed by Borrower and Bank.
