CHANGE IN CONTROL AGREEMENT

September 25, 2009

Aaron Erkan Akyuz

3121 West 69th Street

Apt. 218

Edina, MN  55345

Dear Erkan:

In connection with your hiring as the Executive Vice President of Research and Development of Vital Images, Inc., a Minnesota corporation (the “Company”), we hereby offer you valuable and unique benefits.  The Company considers the establishment and maintenance of a sound and vital management to be essential to protecting and enhancing the best interests of the Company and its shareholders.  In this connection, the Company recognizes that, as is the case with many publicly held corporations, the possibility of a Change in Control may arise and that such possibility and the uncertainty and questions which it may raise among management may result in the departure or distraction of management personnel to the detriment of the Company and its shareholders.

Accordingly, the Board has determined that appropriate steps should be taken to minimize the risk that Company management will depart prior to a Change in Control, thereby leaving the Company without adequate management personnel during such a critical period, and that appropriate steps also be taken to reinforce and encourage the continued attention and dedication of members of the Company’s management to their assigned duties without distraction in circumstances arising from the possibility of a Change in Control.  In particular, the Board believes it important, should the Company or its shareholders receive a proposal for transfer of control, that you be able to continue your management responsibilities without being influenced by the uncertainties of your own personal situation.

The Board recognizes that continuance of your position with the Company involves a substantial commitment to the Company in terms of your personal life and professional career and the possibility of foregoing present and future career opportunities, for which the Company receives substantial benefits.  Therefore, to induce you to remain in the employ of the Company, this Agreement, which has been approved by the Board, sets forth the benefits which the Company agrees will be provided to you in the event your employment with the Company is terminated in connection with a Change in Control under the circumstances described below.

The following terms will have the meaning set forth below unless the context clearly requires otherwise.  Terms defined elsewhere in this Agreement will have the same meaning throughout this Agreement.

ARTICLE I.

DEFINITIONS

1.                                       “Affiliate” means (i) any corporation more than 50% of whose outstanding securities ordinarily having the right to vote at elections of directors is owned directly or indirectly by the Company or (ii) any other form of business entity in which the Company, by virtue of a direct or indirect ownership interest, has the right to elect a majority of the members of such entity’s governing body.

2.                                       “Agreement” means this letter agreement as amended, extended or renewed from time to time in accordance with its terms.

3.                                       “Board” means the board of directors of the Company duly qualified and acting at the time in question.  On and after the date of a Change in Control, any duty of the Board in connection with this Agreement is nondelegable and any attempt by the Board to delegate any such duty is ineffective.

4.                                       “Cause” means:

a.                                       your gross misconduct;

b.                                      your willful and continued failure to perform substantially your duties with the Company (other than any such failure (1) resulting from your Disability or incapacity due to bodily injury or physical or mental illness or (2) relating to changes in your duties after a Change in Control which constitute Good Reason) after a demand for substantial performance is delivered to you by the chair of the Board which specifically identifies the manner in which you have not substantially performed your duties and provides for a reasonable period of time within which you may take corrective actions; or

c.                                       your conviction (including a plea of nolo contendere) of willfully engaging in illegal conduct constituting a felony or gross misdemeanor under federal or state law which is materially and demonstrably injurious to the Company or which impairs your ability to perform substantially your duties for the Company.

An act or failure to act will be considered “gross” or “willful” for this purpose only if done, or omitted to be done, by you in bad faith and without reasonable belief that it was in, or not opposed to, the best interests of the Company.  Any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the Company’s board of directors (or a committee thereof) or based upon the advice of counsel for the Company will be conclusively presumed to be done, or omitted to be done, by you in good faith and in the best interests of the Company.  It is also expressly understood that your attention to matters not directly related to the business of the Company will not provide a basis for termination

2

for Cause so long as the Board did not expressly disapprove in writing of your engagement in such activities either before or within a reasonable period of time after the Board knew or could reasonably have known that you engaged in those activities.  Notwithstanding the foregoing, you may not be terminated for Cause unless and until there has been delivered to you a copy of a resolution duly adopted by the affirmative vote of not less than a majority of the entire membership of the Board at a meeting of the Board called and held for the purpose (after reasonable notice to you and an opportunity for you, together with your counsel, to be heard before the Board), finding that in the good faith opinion of the Board you were guilty of the conduct set forth above in clauses a., b. or c. of this definition and specifying the particulars thereof in detail.

5.                                       “Change in Control” means any of the following:

a.                                       the sale, exchange or other transfer, directly or indirectly, of all or substantially all of the assets of the Company to any Person in one transaction or in a series of related transactions which occur during the twelve-month period ending on the date of the most recent purchase or other acquisition by such Person;

b.                                      any Person is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of (1) 30 percent or more, but not more than 50 percent, of the combined voting power of the outstanding securities of the Company ordinarily having the right to vote at elections of directors, unless the transaction resulting in such ownership has been approved in advance by the “continuing directors” or (2) more than 50 percent of the combined voting power of the outstanding securities of the Company ordinarily having the right to vote at elections of directors (regardless of any approval by the continuing directors);

d.                                      a merger or consolidation to which the Company is a party if the shareholders of the Company immediately prior to the effective date of such merger or consolidation have, solely on account of ownership of securities of the Company at such time, “beneficial ownership” (as defined in Rule 13d-3 under the Exchange Act) immediately following the effective date of such merger or consolidation of securities of the surviving company representing less than 50 percent of the combined voting power of the surviving corporation’s then outstanding securities ordinarily having the right to vote at elections of directors (regardless of any approval by the continuing directors); or

e.                                       the continuing directors cease for any reason to constitute at least a majority of the Board.

For purposes of this Section 1(e), a “continuing director” means any individual who is a member of the Board on October 1, 2009, while he or she is a member of the Board, and any individual who subsequently becomes a member of the Board whose election or nomination for election by the Company’s shareholders was approved by a vote of at least a majority of

3

the directors who are continuing directors (either by a specific vote or by approval of the proxy statement of the Company in which such individual is named as a nominee for director without objection to such nomination).

In all cases, the determination of whether a Change in Control has occurred shall be made in accordance with Code Section 409A and the regulations, notices and other guidance of general applicability issued thereunder.

6.                                       “Code” means the Internal Revenue Code of 1986, as amended.  Any reference to a specific provision of the Code includes a reference to such provision as it may be amended from time to time and to any successor provision.

7.                                       “Company” means Vital Images, Inc. and/or any Affiliate.

8.                                       “Confidential Information” means information which is proprietary to the Company or proprietary to others and entrusted to the Company, whether or not trade secrets. It includes information relating to business plans and to business as conducted or anticipated to be conducted, and to past or current or anticipated products or services.  It also includes, without limitation, information concerning research, development, purchasing, accounting, marketing and selling.  All information which you have a reasonable basis to consider confidential is Confidential Information, whether or not originated by you and without regard to the manner in which you obtain access to that and any other proprietary information.

9.                                       “Date of Termination” following a Change in Control (or prior to a Change in Control if your termination was either a condition of the Change in Control or was at the request or insistence of any Person related to the Change in Control) means:

a.                                       if your employment is to be terminated for Disability, 30 days after Notice of Termination is given (provided that you have not returned to the performance of your duties on a full-time basis during such 30-day period);

b.                                      if your employment is to be terminated by the Company for Cause or by you for Good Reason, the date specified in the Notice of Termination, which date may not be less than 30 days or more than 60 days after the date on which the Notice of Termination is given unless you and the Company otherwise expressly agree;

c.                                       if your employment is to be terminated by the Company for any reason other than Cause, Disability, death or Retirement, the date specified in the Notice of Termination, which in no event may be a date earlier than 90 days after the date on which a Notice of Termination is given, unless an earlier date has been expressly agreed to by you in writing either in advance of, or after; receiving such Notice of Termination; or

4

d.                                      if your employment is terminated by reason of death or Retirement, the date of death or Retirement, respectively.

In the case of termination by the Company of your employment for Cause, if you have not previously expressly agreed in writing to the termination, then within 30 days after receipt by you of the Notice of Termination with respect thereto, you may notify the Company that a dispute exists concerning the termination, in which event the Date of Termination will be the date set either by mutual written agreement of the parties or by the judge or arbitrators in a proceeding as provided in Article VII Section 6 of this Agreement.  During the pendency of any such dispute, you will continue to make yourself available to provide services to the Company and the Company will continue to pay you your full compensation and benefits in effect immediately prior to the date on which the Notice of Termination is given (without regard to any changes to such compensation or benefits which constitute Good Reason) and until the dispute is resolved in accordance with Article VII Section 6 of this Agreement.  You will be entitled to retain the full amount of any such compensation and benefits without regard to the resolution of the dispute unless the judge or arbitrators decide(s) that your claim of a dispute was frivolous or advanced by you in bad faith.

10.                                 “Disability” means a disability as defined in the Company’s long-term disability plan as in effect immediately prior to the Change in Control or; in the absence of such a plan, means permanent and total disability as defined in section 22(e)(3) of the Code.

12.                                 “Good Reason” means:

a.                                       change in your status, position(s), duties or responsibilities as an executive of the Company as in effect immediately prior to the Change in Control which, in your reasonable judgment, is an adverse change (other than, if applicable, any such change directly attributable to the fact that the Company is no longer publicly owned) except in connection with the termination of your employment for Cause, Disability or Retirement or as a result of your death or by you other than for Good Reason;

b.                                      a reduction by the Company in your base salary (or an adverse change in the form or timing of the payment thereof) as in effect immediately prior to the Change in Control or as thereafter increased;

c.                                       the failure by the Company to continue in effect any Plan in which you (and/or your family) are eligible to participate at any time during the 90-day period immediately preceding the Change in Control (or Plans providing you (and/or your family) with at least substantially similar benefits) other than as a result of the normal expiration

5

of any such Plan in accordance with its terms as in effect immediately prior to the 90-day period immediately preceding the time of the Change in Control, or the taking of any action, or the failure to act, by the Company which would adversely affect your (and/or your family’s) continued eligibility to participate in any of such Plans on at least as favorable a basis to you (and/or your family) as is the case on the date of the Change in Control or which would materially reduce your (and/or your family’s) benefits in the future under any of such Plans or deprive you (and/or your family) of any material benefit enjoyed by you (and/or your family) at the time of the Change in Control;

d.                                      the Company’s requiring you to be based more than 30 miles from where your office is located immediately prior to the Change in Control, except for required travel on the Company’s business, and then only to the extent substantially consistent with the business travel obligations which you undertook on behalf of the Company during the 90-day period immediately preceding the Change in Control (without regard to travel related to or in anticipation of the Change in Control);

e.                                       the failure by the Company to obtain from any Successor the assent to this Agreement contemplated by Article VI of this Agreement;

f.                                         any purported termination by the Company of your employment which is not properly effected pursuant to a Notice of Termination and pursuant to any other requirements of this Agreement, and for purposes of this Agreement, no such purported termination will be effective;

g.                                      any refusal by the Company to continue to allow you to attend to matters or engage in activities not directly related to the business of the Company which, at any time prior to the Change in Control, you were not expressly prohibited in writing by the Board from attending to or engaging in; or

h.                                      the termination of your employment by the Company for any reason other than death,  Cause, Disability or Retirement during the twelve (12) months following the month in which a Change in Control occurs.

6

ARTICLE II.

TERM OF AGREEMENT

This Agreement is effective immediately and will continue in effect until October 1, 2010; provided, however; that commencing on October 1, 2010 and each October 1st thereafter, the term of this Agreement will automatically be extended for 12 additional months beyond the expiration date otherwise then in effect, unless at least 90 calendar days prior to any such October 1st, the Company or you has given notice that this Agreement will not be extended; and, provided, further; that if a Change in Control has occurred during the term of this Agreement, this Agreement will continue in effect beyond the termination date then in effect for a period of 12 months following the month during which the Change in Control occurs or, if later, until the date on which the Company’s obligations to you arising under or in connection with this Agreement have been satisfied in full.

ARTICLE III.

CHANGE IN CONTROL BENEFITS

1.                                       Benefits upon a Change in Control Termination.  You will become entitled to the payments and benefits described in clauses (a) and (b) of this Section 1 of Article III, subject to the

7

limitations described in clause (c) of this Section 1 of Article III, and to the benefit of the provisions described in clause (c), if and only if (i) your employment with the Company is terminated by the Company for any reason other than death, Cause, Disability or Retirement, or if you terminate your employment with the Company for Good Reason; and (ii) the termination occurs either within the period beginning on the date of a Change in Control and ending on the last day of the twelfth month that begins after the month during which the Change in Control occurs or prior to a Change in Control if your termination was either a condition of the Change in Control or was at the request or insistence of a Person related to the Change in Control.

a.                                       Cash Payment.  Within ten (10) business days following the Date of Termination or, if later, within ten (10) business days following the date of the Change in Control, the Company will make a lump-sum cash payment to you in an amount equal to your annual base salary in effect on the date of the Change in Control.

b.                                      Welfare Plans. The Company will maintain in full force and effect, for the continued benefit of you and your dependents for a period terminating 24 months after the Date of Termination, all insured and self-insured employee welfare benefit Plans (including, without limitation, medical, life, dental, vision and disability plans) in which you were eligible to participate at any time during the 90-day period immediately preceding the Change in Control, provided that your continued participation is possible under the general terms and provisions of such Plans and any applicable funding media and without regard to any discretionary amendments to such Plans by the Company following the Change in Control (or prior to the Change in Control if amended as a condition or at the request or insistence of a Person (other than the Company) related to the Change in Control) and provided that you continue to pay an amount equal to your regular contribution under such Plans for such participation (based upon your level of benefits and employment status most favorable to you at any time during the 90-day period immediately preceding the Change in Control).  The continuation period under federal and state continuation laws, to the extent applicable, will begin to run from the date on which coverage pursuant to this clause (b) ends.  If, at the end of the 24-month period, you have not previously received or are not then receiving equivalent benefits from a new employer (including coverage for any pre-existing conditions), the Company, pursuant to federal and state law, will provide, for a period of eighteen (18) months (the “COBRA Period”), a continuation of your and your dependents’ coverage under such Plans (the “COBRA Coverage”), provided that you will be required to pay for such benefits during the COBRA Period, should you elect to receive COBRA Coverage.

c.                                       Limitation on Payments and Benefits.  Notwithstanding anything in this Agreement to the contrary, if any of the payments or benefits to be made or provided in connection with this Agreement, together with any other payments, benefits or awards which you have the right to receive from the Company, or any corporation

8

which is a member of an “affiliated group” (as defined in section 1504(a) of the Code without regard to section 1504(b) of the Code) of which the Company is a member (“Affiliate”), constitute an “excess parachute payment” (as defined in section 280G(b) of the Code), two calculations will be performed.  In the first calculation, the payments, benefits or awards will be reduced by the amount the Company deems necessary so that none of the payments or benefits under the Agreement (including from the existing Stock Option and Incentive Plan) are excess parachute payments.  In the second calculation, the payments will not be reduced so as to eliminate an excess parachute payment, but will be reduced by the amount of the applicable excise tax as imposed by section 4999 of the Code.  The two calculations will be compared and the calculation providing the largest net payment to the employee will be utilized.  The calculations must be made in good faith by legal counsel or a certified public accountant selected by the Company, and such determination will be conclusive and binding upon you and the Company.  If a reduction in payments or benefits is required by the comparison above, the payments or benefits under the Agreement shall be reduced in the order that minimizes the amount of total reduction in payments and benefits under the Agreement as a result of this provision.

d.                                      409A Restrictions.  Notwithstanding the foregoing, if any of the payments or other benefits described in this Article III are subject to the requirements of Code Section 409A and the Company determines that you are a “specified employee” as defined in Code Section 409A as of the Date of Termination, such payments shall not be paid or commence earlier than the first day of the seventh month following the Date of Termination.

2.                                       Disposition.  If, on or after the date of a Change in Control, an Affiliate is sold, merged, transferred or in any other manner or for any other reason ceases to be an Affiliate or all or any portion of the business or assets of an Affiliate are sold, transferred or otherwise disposed of and the acquiror is not the Company or an Affiliate (a “Disposition”), and you remain or become employed by the acquiror or an affiliate of the acquiror (as defined in this Agreement but substituting “acquiror” for “Company”) in connection with the Disposition, you will be deemed to have terminated employment on the effective date of the Disposition for purposes of this section unless (a) the acquiror and its affiliates jointly and severally expressly assume and agree, in a manner that is enforceable by you, to perform the obligations of this Agreement to the same extent that the Company would be required to perform if the Disposition had not occurred and (b) the Successor guarantees, in a manner that is enforceable by you, payment and performance by the acquiror.  This Section 2 of Article III shall be applied in accordance with Code Section 409A and the regulations, notices and other guidance of general applicability issued thereunder.

ARTICLE IV.

INDEMNIFICATION

Following a Change in Control, the Company will indemnify and reimburse you to the full extent permitted by law and the Company’s articles of incorporation and bylaws for damages, costs and expenses (including, without limitation, judgments, fines, penalties, settlements and reasonable fees and expenses of your counsel) incurred in connection with all matters, events and transactions relating to your service to or status with the Company or any other corporation, employee benefit plan or other entity with whom you served at the request of the Company.

ARTICLE V.

CONFIDENTIALITY

You will not use, other than in connection with your employment with the Company, or disclose any Confidential Information to any person not employed by the Company or not authorized by the Company to receive such Confidential Information, without the prior written consent of the Company; and you will use reasonable and prudent care to safeguard and protect and prevent the unauthorized disclosure of Confidential Information. Nothing in this Agreement will prevent you from using, disclosing or authorizing the disclosure of any Confidential Information: (a) which is or hereafter becomes part of the public domain or otherwise becomes generally available to the public through no fault of yours; (b) to the extent and upon the terms and conditions that the Company may have previously made the Confidential Information available to certain persons; or (c) to the extent that you are required to disclose such Confidential Information by law or judicial or administrative process.

ARTICLE VI.

SUCCESSORS

The Company will seek to have any Successor, by agreement in form and substance satisfactory to you, assent to the fulfillment by the Company of the Company’s obligations under this Agreement. Failure of the Company to obtain such assent at least three business days prior to the time a Person becomes a Successor (or where the Company does not have at least three business days’ advance notice that a Person may become a Successor, within one business day after having notice that such Person may become or has become a Successor) will constitute Good Reason for termination by you of your employment.  The date on which any such succession becomes effective will be deemed the Date of Termination and Notice of Termination will be deemed to have been given on that date.  A Successor has no rights, authority or power with respect to this Agreement prior to a Change in Control.

ARTICLE VII.

OTHER PROVISIONS

1.                                       Binding Agreement.  This Agreement inures to the benefit of, and is enforceable by, you, your personal and legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees. If you die while any amount would still be payable to you under this Agreement if you had continued to live, all such amounts, unless otherwise

10

provided in this Agreement, will be paid in accordance with the terms of this Agreement to your devisee, legatee or other designee or; if there be no such designee, to your estate.

2.                                       No Mitigation.  You will not be required to mitigate the amount of any payments or benefits the Company becomes obligated to make or provide to you in connection with this Agreement by seeking other employment or otherwise. The payments or benefits to be made or provided to you in connection with this Agreement may not be reduced, offset or subject to recovery by the Company by any payments or benefits you may receive from other employment or otherwise.

3.                                       No Setoff.  The Company has no right to delay or setoff payments or benefits owed to you under this Agreement against amounts owed or claimed to be owed by you to the Company under this Agreement or otherwise.

4.                                       Taxes.  All payments and benefits to be made or provided to you in connection with this Agreement will be subject to required withholding of federal, state and local income, excise and employment-related taxes.

5.                                       Notices.  For the purposes of this Agreement, notices and all other communications provided for in, or required under, this Agreement must be in writing and will be deemed to have been duly given when personally delivered or when mailed by United States registered or certified mail, return receipt requested, postage prepaid and addressed to each party’s respective address set forth on the first page of this Agreement (provided that all notices to the Company must be directed to the attention of the chair of the Board), or to such other address as either party may have furnished to the other in writing in accordance with these provisions, except that notice of change of address will be effective only upon receipt.

6.                                       Disputes.  If you so elect, any dispute, controversy or claim arising under or in connection with this Agreement will be settled exclusively by binding arbitration administered by the American Arbitration Association in Minneapolis, Minnesota in accordance with the Commercial Arbitration Rules of the American Arbitration Association then in effect.  Judgment may be entered on the arbitrator’s award in any court having jurisdiction; provided, that you may seek specific performance of your right to receive payment or benefits until the Date of Termination during the pendency of any dispute or controversy arising under or in connection with this Agreement.  The Company will be entitled to seek an injunction or restraining order in a court of competent jurisdiction (within or without the State of Minnesota) to enforce the provisions of Article V of this Agreement.

7.                                       Jurisdiction.  Except as specifically provided otherwise in this Agreement, the parties agree that any action or proceeding arising under or in connection with this Agreement must be brought in a court of competent jurisdiction in the State of Minnesota, and hereby consent to the exclusive jurisdiction of said courts for this purpose and agree not to assert that such courts are an inconvenient forum

11

8.                                       Related Agreements.  To the extent that any provision of any other Plan or agreement between the Company and you limits, qualifies or is inconsistent with any provision of this Agreement, then for purposes of this Agreement, while such other Plan or agreement remains in force, the provision of this Agreement will control and such provision of such other Plan or agreement will be deemed to have been superseded, and to be of no force or effect, as if such other agreement had been formally amended to the extent necessary to accomplish such purpose.  Nothing in this Agreement prevents or limits your continuing or future participation in any Plan provided by the Company and for which you may qualify, and nothing in this Agreement limits or otherwise affects the rights you may have under any Plans or other agreements with the Company.  Amounts which are vested benefits or which you are otherwise entitled to receive under any Plan or other agreement with the Company at or subsequent to the Date of Termination will be payable in accordance with such Plan or other agreement.

9.                                       No Employment or Service Contract.  Nothing in this Agreement is intended to provide you with any right to continue in the employ of the Company for any period of specific duration or interfere with or otherwise restrict in any way your rights or the rights of the Company, which rights are hereby expressly reserved by each, to terminate your employment at any time for any reason or no reason whatsoever, with or without cause.

10.                                 Funding and Payment.  Benefits payable under this Agreement will be paid only from the general assets of the Company.  No person has any right to or interest in any specific assets of the Company by reason of this Agreement.  To the extent benefits under this Agreement are not paid when due to any individual, he or she is a general unsecured creditor of the Company with respect to any amounts due.  The Company with whom you were employed immediately before your Date of Termination has primary responsibility for benefits to which you or any other person are entitled pursuant to this Agreement but to the extent such Company is unable or unwilling to provide such benefits, the Company and each other Affiliate are jointly and severally responsible therefor to the extent permitted by applicable law.  If you were simultaneously employed by more than one Company immediately before your Date of Termination, each such Company has primary responsibility for a portion of the benefits to which you or any other person are entitled pursuant to this Agreement that bears the same ratio to the total benefits to which you or such other person are entitled pursuant to this Agreement as your base pay from the Company immediately before your Date of Termination bears to your aggregate base pay from all such Companies.

11.                                 Survival.  The respective obligations of, and benefits afforded to, the Company and you which by their express terms or clear intent survive termination of your employment with the Company or termination of this Agreement, as the case may be, including without limitation the provisions of Articles III, IV, V and VI and Sections 3, 4, 5 and 6 of Article VII of this Agreement, will survive termination of your employment with the Company or termination of this Agreement, as the case may be, and will remain in full force and effect according to their terms.

12

ARTICLE VIII.

MISCELLANEOUS

1.                                       Modification and Waiver.  No provision of this Agreement may be modified, waived or discharged unless such modification, waiver or discharge is agreed to in a writing signed by you and the chair of the Board. No waiver by any party to this Agreement at any time of any breach by another party to this Agreement of, or of compliance with, any condition or provision of this Agreement to be performed by such party will be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time.  Notwithstanding anything in this Agreement to the contrary, the Company expressly reserves the right to amend this Agreement to the extent necessary to comply with Code Section 409A, as it may be amended from time to time, and the regulations, notices and other guidance of general applicability issued thereunder.

2.                                       Entire Agreement.  No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter to this Agreement have been made by any party which are not expressly set forth in this Agreement.

3.                                       Governing Law.  This Agreement and the legal relations among the parties as to all matters, including, without limitation, matters of validity, interpretation, construction, performance and remedies, will be governed by and construed exclusively in accordance with the internal laws of the State of Minnesota (without regard to the conflict of laws principles of any jurisdiction).
