(as defined below). 
 WHEREAS, concurrently with the execution hereof, Parent, Merger Sub and TriVascular Technologies, Inc., a Delaware
corporation (the “Company”), are entering into an Agreement and Plan of Merger, dated as of the date hereof (as it may be amended from time to time, the “Merger Agreement”), which provides, among other things, for

practicable after the Company Stockholder Approval has been obtained; 
 WHEREAS, as of the date hereof, the Stockholder is the record and
beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of the number of shares of common stock, par value $0.01 per share of the Company (“Company Common Stock”) set forth on the signature page hereto (such shares,
in addition to any shares of Company Common Stock acquired in any manner after the date of this Agreement, being referred to herein as the “Subject Shares”); and 

WHEREAS, as a condition to their willingness to enter into the Merger Agreement, and as an inducement and in consideration for Parent and
Merger Sub to enter into the Merger Agreement, the Stockholder, on his, her or its own account with respect to the Subject Shares, has agreed to enter into this Agreement. 

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below and
for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, do hereby agree as follows: 

ARTICLE I 
 AGREEMENT TO
VOTE 
 1.1 Agreement to Vote. Subject to the terms of this Agreement, the Stockholder hereby irrevocably and unconditionally
agrees that, until this Agreement is terminated in accordance with Section 5.2, at the Company Stockholder Meeting or any other annual or special meeting of the stockholders of the Company, however called, including any adjournment or
postponement thereof, and in connection with any action proposed to be taken by written consent of the stockholders of the Company, the Stockholder shall, in each case to the fullest extent that the Subject Shares are entitled to vote thereon:
(a) appear at each such meeting or otherwise cause all of the Subject Shares to be counted as present thereat for purposes of determining a quorum; and (b) be present (in person or by proxy) and vote (or cause to be voted), or deliver (or
cause to be delivered) a written consent with respect to, all of the Subject Shares: (i) for adoption of the Merger Agreement and for the approval of the Transactions; (ii) for any proposal to adjourn or postpone the Company Stockholder
Meeting or such other meeting of the Company’s stockholders to a later date if there are not sufficient votes to adopt the Merger Agreement; (iii) against any action or agreement that would result in a breach of any covenant,
representation or warranty or any other obligation or agreement of the Company contained in the Merger Agreement, or of the Stockholder contained in this Agreement; (iv) against any Company Takeover Proposal and or any other action, agreement
or transaction involving the Company that is intended, or would reasonably be 






 expected, to impede, interfere with, delay, postpone, adversely affect or prevent the consummation of the
Transactions; and (v) in favor of any other matter necessary to consummate the Transactions. Subject to the proxy granted under Section 1.2 below, the Stockholder shall retain at all times the right to vote the Subject Shares in the
Stockholder’s sole discretion, and without any other limitation, on any matters other than those set forth in this Section 1.1 that are at any time or from time to time presented for consideration to the Company’s stockholders
generally. 
 1.2 Irrevocable Proxy. Solely with respect to the matters described in Section 1.1, until this Agreement is
terminated in accordance with Section 5.2, the Stockholder hereby irrevocably appoints Parent as his, her or its attorney and proxy with full power of substitution and resubstitution, to the full extent of the Stockholder’s voting
rights with respect to all of the Subject Shares (which proxy is irrevocable and which appointment is coupled with an interest, including for purposes of Section 212 of the DGCL) to vote, and to execute written consents with respect to, all of
the Subject Shares solely on the matters described in Section 1.1, and in accordance therewith. The Stockholder agrees to execute any further agreement or form reasonably necessary or appropriate to confirm and effectuate the grant of
the proxy contained herein. Such proxy shall automatically terminate upon the valid termination of this Agreement in accordance with its terms. Parent may terminate this proxy with respect to the Stockholder at any time at its sole election by
written notice provided to the Stockholder. 
 ARTICLE II 

REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDER 

The Stockholder represents and warrants, on his, her or its own account with respect to the Subject Shares, to Parent and Merger Sub that:

 2.1 Authorization; Binding Agreement. The Stockholder has full legal capacity, right and authority to execute and deliver this
Agreement and to perform the Stockholder’s obligations hereunder. This Agreement has been duly and validly executed and delivered by the Stockholder and constitutes a valid and binding obligation of the Stockholder enforceable against the
Stockholder in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other similar Laws relating to or affecting creditors’ rights generally and general equitable
principles (whether considered in a proceeding in equity or at law) (the “Enforceability Exceptions”). If the Stockholder is married, and any of the Subject Shares of the Stockholder constitute community property or otherwise need
spousal or other approval for this Agreement to be legal, valid and binding, this Agreement has been duly executed and delivered by the Stockholder’s spouse and, assuming the due authorization, execution and delivery hereof by Parent and Merger
Sub, is enforceable against the Stockholder’s spouse in accordance with its terms, subject to the Enforceability Exceptions. 
 2.2
Non-Contravention. Neither the execution and delivery of this Agreement by the Stockholder nor the consummation of the transactions contemplated hereby nor compliance by the Stockholder with any provisions herein will (a) violate, conflict
with, or result in a breach of any provisions of, or require any consent, waiver or approval or result in a default or loss of a benefit (or give rise to any right of termination, cancellation, modification or acceleration or any event that, with
the giving of notice, the passage of time or otherwise, would constitute a default or give rise to any such right) under any of the terms, conditions or provisions of any note, license, agreement, contract, indenture or other instrument or
obligation to which the Stockholder is a party or by which the Stockholder or any of his, her or its assets may be bound, (b) result (or, with the giving of notice, the passage of time or otherwise, would result) in the creation or imposition
of any mortgage, lien, pledge, charge, security interest or encumbrance of any kind on any asset of the Stockholder (other than one created by Parent or Merger Sub), or (c) violate any order, writ, injunction or decree applicable to the
Stockholder or by which any of his, her or its assets are bound, except, with respect to the foregoing clauses (a), (b) and (c), as 

  
 2 







 
would not impair or adversely affect Stockholder’s ability to perform Stockholder’s obligations under this Agreement. 

2.3 Ownership of Subject Shares; Total Shares. Such Stockholder is the record and beneficial owner (as defined in Rule 13d-3 under
the Exchange Act) of all of the Subject Shares and has good and marketable title to all of the Subject Shares free and clear of any liens, claims, proxies, voting trusts or agreements, options, rights, understandings or arrangements or any other
encumbrances or restrictions whatsoever on title, transfer or exercise of any rights of a stockholder in respect of such Subject Shares (collectively, “Encumbrances”), except for any such Encumbrance that may be imposed pursuant to
(a) this Agreement and (b) any applicable restrictions on transfer under the Securities Act or any state securities law (collectively, “Permitted Encumbrances”). For the avoidance of doubt, the fact that the Subject Shares
are held in a margin account shall not be deemed to be an Encumbrance hereunder. The Subject Shares constitute all of the shares of “voting stock” of the Company of which the Stockholder is the “owner” (as such terms are defined
in Section 203 of the DGCL) as of the date hereof. 
 2.4 Voting Power. The Stockholder has full voting power with respect to
all of the Subject Shares, and full power of disposition, full power to issue instructions with respect to the matters set forth herein and full power to agree to all of the matters set forth in this Agreement, in each case with respect to all of
the Subject Shares, subject to applicable federal securities laws and the terms of this Agreement. 
 2.5 Reliance. The Stockholder
understands and acknowledges that Parent and Merger Sub are entering into the Merger Agreement in reliance upon the Stockholder’s execution, delivery and performance of this Agreement. 

2.6 Brokers. Except as otherwise disclosed in the Merger Agreement, no broker, finder, financial advisor, investment banker or other
person is entitled to any brokerage, finder’s, financial advisor’s or other similar fee or commission from the Company in connection with the transactions contemplated hereby based upon arrangements made by or on behalf of the Stockholder.

 ARTICLE III 

REPRESENTATIONS AND WARRANTIES OF PARENT AND MERGER SUB 

Parent and Merger Sub represent and warrant to the Stockholder that: 

3.1 Organization and Qualification. Each of Parent and Merger Sub is a duly organized and validly existing corporation in good standing
under the Laws of the state of Delaware. All of the issued and outstanding capital stock of Merger Sub is owned directly by Parent. 

3.2 Authority for this Agreement. Each of Parent and Merger Sub has all requisite entity power and authority to execute, deliver and
perform its obligations under this Agreement and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement by Parent and Merger Sub have been duly and validly authorized by all necessary corporate action on the
part of each of Parent and Merger Sub, and no other corporate proceedings on the part of Parent and Merger Sub are necessary to authorize this Agreement. This Agreement has been duly and validly executed and delivered by Parent and Merger Sub and,
assuming the due authorization, execution and delivery by the Stockholder, constitutes the legal, valid and binding obligation of each of Parent and Merger Sub, enforceable against each of Parent and Merger Sub in accordance with its terms, except
as enforceability may be limited by the Enforceability Exceptions.

 ARTICLE IV 

ADDITIONAL COVENANTS 
 The
Stockholder hereby covenants and agrees that until the termination of this Agreement: 
 4.1 No Transfer; No Inconsistent
Arrangements. Except as provided hereunder or under the Merger Agreement, from and after the date hereof and until the earlier of the date this Agreement is terminated and the receipt of the Company Stockholder Approval, the Stockholder shall
not, directly or indirectly, (a) create or permit to exist any Encumbrance, other than Permitted Encumbrances, on any of the Subject Shares, (b) transfer, sell, assign, gift, hedge, pledge or otherwise dispose of, or enter into any
derivative arrangement with respect to (collectively, “Transfer”), any of the Subject Shares, or any right or interest therein (or consent to any of the foregoing), (c) enter into any Contract with respect to any Transfer of
the Subject Shares or any interest therein, (d) grant or permit the grant of any proxy, power-of-attorney or other authorization or consent in or with respect to any of the Subject Shares, (e) deposit or permit the deposit of any of the
Subject Shares into a voting trust or enter into a voting agreement or arrangement with respect to any of the Subject Shares, or (f) take or permit any other action that would in any way restrict, limit or interfere with the performance of the
Stockholder’s obligations hereunder or otherwise make any representation or warranty of the Stockholder herein untrue or incorrect. Any action taken in violation of the foregoing sentence shall be null and void ab initio. Notwithstanding
the foregoing, the Stockholder may Transfer the Subject Shares (1) if such Stockholder is a partnership, limited liability company or trust, to one or more partners or members of such Stockholder or to an affiliated corporation under common
control with such Stockholder or to any trustee or beneficiary of the trust, (2) if such Stockholder is an individual, (w) to any member of the Stockholder’s immediate family, (x) to a trust for the sole benefit of the
Stockholder or any member of the Stockholder’s immediate family, the sole trustees of which are the Stockholder or any member of the Stockholder’s immediate family, (y) by will, or (z) under the laws of intestacy upon the death
of the Stockholder, (3) to a charitable organization, including but not limited to, a private charitable foundation under Section 501(c)(3) of the Code or (4) pursuant to a Rule 10b5-1 in place prior to the date of this Agreement;
provided, that a Transfer referred to in clause (1), (2)(w), (2)(x), (2)(y) or (3) of this sentence shall be permitted only if the transferee agrees in writing to accept the Subject Shares subject to the terms of this Agreement
and to be bound by the terms of this Agreement and to agree and acknowledge that such person shall constitute a Stockholder for all purposes of this Agreement. If any involuntary Transfer of any of the Subject Shares shall occur (including, but not
limited to, a sale by the Stockholder’s trustee in any bankruptcy, or a sale to a purchaser at any creditor’s or court sale), the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of
the initial transferee) shall take and hold the Subject Shares subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until valid termination of this Agreement. Notwithstanding
the foregoing, the Stockholder may make such Transfers of the Subject Shares as Parent may agree in writing in its sole discretion. 

4.2 No Exercise of Appraisal Rights. The Stockholder forever waives and agrees not to exercise any appraisal rights or dissenters’
rights pursuant to Section 262 of the DGCL or otherwise in respect of the Subject Shares that may arise in connection with the Merger. 

4.3 Documentation and Information. The Stockholder shall not make any public announcement regarding this Agreement and the transactions
contemplated hereby without the prior written consent of Parent, except as may be required by applicable Law or in compliance with the rules or regulations of the SEC, any other Governmental Entity or the Nasdaq or any other national securities
exchange as determined in the reasonable discretion of the Stockholder in consultation with his, her or its counsel (provided that notice of any such disclosure will be provided to Parent). The Stockholder consents to and hereby authorizes Parent
and Merger Sub to publish and disclose in all documents and 

  
 4 







 
schedules filed with the SEC, and any press release or other disclosure document that Parent or Merger Sub reasonably determines to be necessary in connection with the Merger and any other
transactions contemplated by the Merger Agreement, the Stockholder’s identity and ownership of the Subject Shares, the existence of this Agreement and the nature of the Stockholder’s commitments and obligations under this Agreement, and
the Stockholder acknowledges that Parent and Merger Sub will file this Agreement or a form hereof with the SEC or any other Governmental Entity. The Stockholder agrees to promptly give Parent any information it may reasonably require for the
preparation of any such disclosure documents, and the Stockholder agrees to promptly notify Parent of any required corrections with respect to any written information supplied by the Stockholder specifically for use in any such disclosure document,
if and to the extent that any such information shall have become false or misleading in any material respect. 
 4.4 Adjustments. In
the event of any stock split, stock dividend, merger, reclassification, combination, exchange of shares or the like of the capital stock of the Company affecting the Subject Shares, the terms of this Agreement shall apply to the resulting
securities. 
 4.5 Waiver of Certain Actions. The Stockholder hereby agrees not to commence or participate in, and to take all
actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Parent, Merger Sub, the Company or any of their respective successors (a) challenging the validity of, or seeking to
enjoin or delay the operation of, any provision of this Agreement or the Merger Agreement (including any claim seeking to enjoin or delay the consummation of the Merger) or (b) alleging a breach of any duty of the Company Board of Directors in
connection with the Merger Agreement, this Agreement or the transactions contemplated thereby or hereby. 
 4.6 No Solicitation. The
Stockholder shall, and shall cause his, her or its Affiliates (which term, solely for purposes of this Section 4.6, shall be deemed to exclude the Company and its Subsidiaries) and his, her or its and their respective Representatives,
not to, directly or indirectly, (a) solicit, initiate, knowingly encourage or knowingly facilitate any inquiries regarding, or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, a Company Takeover
Proposal, (b) engage in, continue or otherwise participate in any discussions or negotiations regarding, or furnish to any other Person any information in connection with or for the purpose of knowingly encouraging or facilitating, a Company
Takeover Proposal (other than, solely in response to an unsolicited inquiry, to refer the inquiring person to this Section 4.6 and to Section 5.3 of the Merger Agreement and to limit his, her or its conversation or other
communication exclusively to such referral), or (c) support, recommend, endorse or approve, or propose to support, recommend, endorse or approve, any Company Takeover Proposal or enter into any letter of intent or similar document, agreement,
commitment or agreement in principle relating to or facilitating a Company Takeover Proposal. The foregoing notwithstanding, no announcement or disclosure made by, nor any action taken by, the Company Board of Directors (including, without
limitation, a Company Adverse Recommendation Change) shall be deemed to be a breach of this Section 4.6 by the Stockholder or Affiliate thereof that serves as a director of the Company so long as such announcement, disclosure or action
does not constitute a breach of the Merger Agreement by the Company.

to or in connection with this Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware, without giving effect to any choice or conflict of Law provision or rule (whether of the State of Delaware or any other
jurisdiction) that would cause the application of the Laws of any jurisdiction other than the State of Delaware. 
 5.9 Descriptive
Headings. The descriptive headings herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Agreement. 

5.10 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in
this Agreement, express or implied, is intended to confer upon any other person any rights or remedies of any nature whatsoever under or by reason of this Agreement. 

5.11 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of
Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term 

  
 7

as closely as possible in a mutually acceptable manner. 
 5.12 Counterparts. This Agreement may be executed in counterparts, each of
which shall be deemed to be an original, but all of which, taken together, shall constitute one and the same agreement. This Agreement or any counterpart may be executed and delivered by facsimile copies or delivered by electronic communications by

 5.13 Interpretation. The words “hereof,”
“herein,” “hereby,” “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole and not to any particular provision of this Agreement, and article, section,

the parties and no presumption or burden of proof shall arise favoring or disfavoring any person by virtue of the authorship of any provision of this Agreement. 

5.14 Further Assurances. The Stockholder will execute and deliver, or cause to be executed and delivered, all further documents and
instruments and use his, her or its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws and regulations, to perform his, her or its

5.16 Stockholder Capacity. The Stockholder shall not be deemed to make any agreement or understanding in this Agreement in the capacity
as a director or officer of the Company. The Stockholder is entering into this Agreement solely in the Stockholder’s capacity as the record holder or beneficial owner of, or as a trust whose beneficiaries are the beneficial owners of, the
Subject Shares. Nothing herein shall be construed as preventing or limiting a Stockholder, or a director, officer or employee of a Stockholder or affiliate of a Stockholder, who is an officer or director of the Company from taking (or omitting to
take) any action in his or her capacity as a director or officer of the Company or otherwise fulfilling the obligations of such office (including the performance of obligations required by the fiduciary obligations of such Stockholder, or director,
officer or employee of a Stockholder or affiliate of a Stockholder, acting solely in his or her capacity as an officer or director of the Company). The taking of any actions (or any failures to act) by the Stockholder in the Stockholder’s
capacity as a director or officer of the Company shall not be deemed to constitute a breach of this Agreement, regardless of the circumstances related thereto so long as no such action is or would be a breach or violation of any provision of the
Merger Agreement if taken by an officer or director of the Company acting in such capacity.
