Dear Dawn:

Boingo Wireless, Inc. (the “Company”) is pleased to offer you continuing employment on the following terms, effective as of January 1, 2013 (the “Effective Date”).

1.                                      Position.  Your title and position with the Company will be Senior Vice President of Marketing and Sales, and you will report directly to the Chief Executive Officer.  This is a full-time position and your place of employment will be our headquarters in Los Angeles.  While you render services to the Company, you will not engage in any other employment, consulting or other business activity (whether full-time or part-time) that would create a conflict of interest with the Company.  By signing this Agreement, you confirm to the Company that you have no contractual commitments or other legal obligations that would prohibit you from performing your duties for the Company.

2.                                      Cash Compensation.  Beginning on the Effective Date, your annual base salary will be $240,000 per year, payable in accordance with the Company’s standard payroll schedule.  This salary will be subject to adjustment pursuant to the Company’s employee compensation policies in effect from time to time. In addition, you will continue to be eligible to be considered for a cash-incentive bonus for each fiscal year of the Company.  The bonus (if any) will be awarded based on objective or subjective criteria established and approved by the Compensation Committee of the Board.  Your target bonus will be equal to 55% of your annual base salary, measured as of the last day of each fiscal year.  Any bonus for a fiscal year will be paid within 2½ months after the close of that fiscal year, but only if you are still employed by the Company at the time of payment.  The determinations of the Compensation Committee with respect to your bonus will be final and binding.

3.                                      Employee Benefits.  As a regular employee of the Company, you will be eligible to participate in the Company’s standard employee benefits programs, as such are in effect from time to time.  In addition, you will be entitled to paid vacation in accordance with the Company’s vacation policy, as in effect from time to time.

4.                                      Payments Upon Termination.  If your employment with the Company terminates other than as set forth in Section 5 below, then (a) all vesting will cease immediately with respect to your then-outstanding Equity Awards and (b) the only amounts payable to you by the Company will be (i) any unpaid base salary due for periods prior to the date of termination of your employment and (ii) any accrued but unused vacation through such termination date.  Such payments, if any, will be made promptly upon termination and within the period of time mandated by law.

5.                                      Severance Benefits.

(a)                                 General.  If you are subject to an Involuntary Termination, then you will be entitled to the benefits described in this Section 5.  However, you will not be entitled to any of the benefits described in this Section 5 unless you have (i) returned all Company property in your possession, (ii) resigned as a member of the Board and of the boards of directors of all of the Company’s subsidiaries, to the extent applicable, and (iii) executed a general release of all claims that you may have against the Company or persons affiliated with the Company, substantially in the form attached hereto as Exhibit A (the “Release”).  You must execute and return the release on or before the date specified by the Company in the Release (the “Release Deadline”).  The Release Deadline will in no event be later than fifty (50) days after your Separation.  If you fail to return the Release on or before the Release Deadline, or if you revoke the Release, then you will not be entitled to the benefits described in this Section 5.

Notwithstanding the foregoing, the Company may immediately discontinue all benefits or revoke any vesting acceleration described in this Section 5 (in addition to pursuing all other legal and equitable remedies) if you breach the Employee Inventions and Confidentiality Agreement or the Mutual Agreement to Arbitrate Claims between you and the Company that you previously signed (collectively, the “Confidentiality Agreement”), a copy of which is attached hereto as Exhibit B, the terms of Section 7 below or any other material agreement with the Company that by its terms continues in force following your Separation.

(b)                                 Termination Not in Connection With Change in Control.  Subject to the requirements set forth in Section 5(a) above, if you experience an Involuntary Termination either prior to a Change in Control or more than twelve (12) months after a Change in Control, then you will be entitled to the following:

(i)                                     Salary Continuation.  The Company will continue to pay your base salary for a period beginning on the day after your Separation and ending on the date nine (9) months after your Separation. Your base salary will be paid at the rate in effect at the time of your Separation and in accordance with the Company’s standard payroll procedures.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, the salary continuation payments will commence within sixty (60) days after your Separation and, once they commence, will include any unpaid amounts accrued from the date of your Separation.  However, if the sixty (60)-day period described in the preceding sentence spans two calendar years, then the payments will in any event begin in the second calendar year.

2

(ii)                                  Additional Payment in Lieu of Health Benefit.  The Company will pay you a lump sum amount equal to the product of (A) nine (9) and (B) the monthly amount the Company was paying on behalf of you and your eligible dependents pursuant to the Company’s health insurance plans in which you or your dependents were participants as of the day of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

(iii)                               Equity Acceleration.  You will receive nine (9) months of vesting credit under your then-outstanding Equity Awards; provided, however, that in the event acceleration of the settlement or distribution date of an award would result in additional taxes and penalties under Section 409A of the Code, then the vesting of such award shall accelerate but settlement or distribution of award shares (or cash, if applicable) shall occur on the date(s) specified in the agreement governing the award.

(c)                                  Termination in Connection With Change in Control.  Subject to the requirements set forth in Section 5(a) above, if you experience an Involuntary Termination within twelve (12) months following a Change in Control, then you will be entitled to the following:

(i)                                     Salary Continuation.  The Company will continue to pay your base salary for a period beginning on the day after your Separation and ending on the date twelve (12) months after your Separation. Your base salary will be paid at the rate in effect at the time of your Separation and in accordance with the Company’s standard payroll procedures.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, the salary continuation payments will commence within sixty (60) days after your Separation and, once they commence, will include any unpaid amounts accrued from the date of your Separation.  However, if the sixty (60)-day period described in the preceding sentence spans two calendar years, then the payments will in any event begin in the second calendar year.

(ii)                                  Target Bonus.  The Company will pay you a lump sum equal to your annual target bonus in the year of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

(iii)                               Additional Payment in Lieu of Health Benefit.  The Company will pay you a lump sum amount equal to the product of (A) twelve (12) and (B) the monthly amount the Company was paying on behalf of you and your eligible dependents pursuant to the Company’s health insurance plans in which you or your dependents were participants as of the day of your Separation.  Subject to the Company’s having first received an effective Release pursuant to Section 5(a) above, such payment will be made

3

within sixty (60) days after your Separation; however, if such sixty (60)-day period spans two calendar years, then the payment will be made in the second calendar year.

(iv)                              Equity Acceleration.  You will receive full vesting credit under your then-outstanding Equity Awards; provided, however, that in the event acceleration of the settlement or distribution date of an award would result in additional taxes and penalties under Section 409A of the Code, then the vesting of such award shall accelerate but settlement or distribution of award shares (or cash, if applicable) shall occur on the date(s) specified in the agreement governing the award.

6.                                      Limitation on Payments.

(a)                                 Scope of Limitation.  This Section 6 will apply only if the accounting firm serving as the Company’s independent public accountants immediately prior to a Change in Control (the “Accounting Firm”) determines that the after-tax value of all Payments (as defined below) to you under Section 5 of this Agreement, taking into account the effect of all federal, state and local income taxes, employment taxes and excise taxes applicable to you (including the excise tax under Section 4999 of the Code), will be greater after the application of this Section 6 than it was before the application of this Section 6.  If this Section 6 applies, it will supersede any contrary provision of this Agreement.  For purposes of this Section 6, the term “Company” will also include affiliated corporations to the extent determined by the Accounting Firm in accordance with Section 280G(d)(5) of the Code.

(b)                                 Basic Rule.  In the event that the Accounting Firm determines that any payment or transfer by the Company to or for your benefit (a “Payment”) would be nondeductible by the Company for federal income tax purposes because of the provisions concerning “excess parachute payments” in Section 280G of the Code and pursuant to the regulations thereunder, then provided that Subsection (a) results in applicable of this Section 6, the aggregate present value of all Payments will be reduced (but not below zero) to the Reduced Amount.  For purposes of this Section 6, the “Reduced Amount” will be the amount, expressed as a present value, which maximizes the aggregate present value of the Payments without causing any Payment to be nondeductible by the Company because of Section 280G of the Code.

(c)                                  Reduction of Payments.  If the Accounting Firm determines that any Payment would be nondeductible by the Company because of Section 280G of the Code, and if none of the Payments is subject to Section 409A of the Code, then the reduction will occur in the manner you elect in writing prior to the date of payment; provided, however, that if the manner elected by you pursuant to this sentence could in the opinion of the Company result in any of the Payments becoming subject to Section 409A of the Code, then the following sentence will instead apply.  If any Payment is subject to Section 409A of the Code, or if you fail to elect an order under the preceding sentence, then the reduction will occur in the following order: (i) cancellation of acceleration of vesting of any Equity Awards for which the exercise price (if any) exceeds the then-fair market value of the underlying Stock; (ii) reduction of cash payments (with such reduction being applied to the payments in the reverse order in which they would otherwise be made (that is, later payments will be reduced before earlier payments)); and (iii) cancellation of acceleration of vesting of Equity Awards not covered under (i) above; provided, however, that

4

in the event that acceleration of vesting of Equity Awards is to be cancelled, such acceleration of vesting will be cancelled in the reverse order of the date of grant of such Equity Awards (that is, later Equity Awards will be canceled before earlier Equity Awards).

(d)                                 Fees of Accounting Firm and Required Data.  The Company will pay all fees, expenses and other costs associated with retaining the Accounting Firm for the purposes described in this Section 6.  You and the Company will provide to the Accounting Firm all data in the Company’s possession or under its control that the Accounting Firm reasonably requires for the purposes described in this Section 6.

7.                                      Further Obligations to the Company.

(a)                                 General.  You acknowledge your obligations under, and agree to comply with, all applicable laws and all Company policies in effect at all times and from time to time during your employment with the Company.  You further acknowledge and agree that such applicable laws or policies may relate to the general terms of your employment with the Company or to a specific component of your compensation. By way of example, such applicable laws or policies may include any Company recoupment or clawback policy, insider trading policy or code(s) of conduct or other policies adopted under, pursuant to or in light of, or requirements imposed by, the Sarbanes-Oxley Act of 2002 or the Dodd-Frank Wall Street Reform and Consumer Protection Act.

(b)                                 Confidential Information.  You agree to execute such additional documents as may be necessary to protect the Company’s confidential and proprietary information, which such documents will supplement the Confidentiality Agreement (which such agreement will continue in full force and effect).

8.                                      Employment Relationship.  Employment with the Company is for no specific period of time.  Your employment with the Company remains “at will,” meaning that either you or the Company may terminate your employment at any time and for any reason, with or without cause.  Any contrary representations that may have been made to you are superseded by this Agreement.  This is the full and complete agreement between you and the Company on this term.  Although your job duties, title, compensation and benefits, as well as the Company’s personnel policies and procedures, may change from time to time, the “at will” nature of your employment may only be changed in an express written agreement signed by you and a duly authorized officer of the Company (other than you).

9.                                      Tax Matters.

(a)                                 General.  All forms of compensation referred to in this Agreement are subject to reduction to reflect applicable withholding and payroll taxes and other deductions required by law. You are encouraged to obtain your own tax advice regarding your compensation from the Company.  You agree that the Company does not have a duty to design its compensation policies in a manner that minimizes your tax liabilities, and you will not make any claim against the Company or its Board related to tax liabilities arising from your compensation.

5

(b)                                 Section 409A.  For purposes of Section 409A of the Code, each payment under Section 5 is hereby designated as a separate payment for purposes of Treasury Regulation 1.409A-2(b)(2).  If the Company determines that you are a “specified employee” under Section 409A(a)(2)(B)(i) of the Code at the time of your Separation, then (i) any payments under this Agreement, to the extent that they are not exempt from Section 409A of the Code (including by operation of the next following sentence) and otherwise subject to the taxes imposed under Section 409A(a)(1) of the Code (a “Deferred Payment”), will commence on the first business day following (A) the expiration of the six-month period measured from your Separation or (B) the date of your death and (ii) the installments that otherwise would have been paid prior to such date will be paid in a lump sum when such payments commence.  Notwithstanding the foregoing, any amount paid under this Agreement that either (1) satisfies the requirements of the “short-term deferral” rule set forth in Treasury Regulation 1.409A-1(b)(4); or (2) (A) qualifies as a payment made as a result of an involuntary separation from service pursuant to Treasury Regulation 1.409A-1(b)(9)(iii), and (B) does not exceed the Section 409A Limit will not constitute a Deferred Payment.  The provisions of this Agreement are intended to comply with, or be exempt from, the requirements of Section 409A of the Code so that none of the payments and benefits to be provided under this Agreement will be subject to the additional tax imposed under Section 409A of the Code, and any ambiguities herein will be interpreted to so comply or be exempt. You and the Company agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions as are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to you under Section 409A of the Code. In no event will the Company reimburse you for any taxes that may be imposed on you as result of Section 409A of the Code.

10.                               Interpretation, Amendment and Enforcement.  Upon the Effective Date, this Agreement will constitute the complete agreement between you and the Company, contain all of the terms of your employment with the Company and supersede and replace any prior agreements, policies, representations or understandings (whether written, oral, implied or otherwise) between you and the Company, including your participation in the Company’s Severance Benefits Policy.  This Agreement may not be amended or modified, except by an express written agreement signed by both you and a duly authorized officer of the Company.  The terms of this Agreement and the resolution of any disputes as to the meaning, effect, performance or validity of this Agreement or arising out of, related to, or in any way connected with, this Agreement, your employment with the Company or any other relationship between you and the Company (the “Disputes”) will be governed by California law, excluding laws relating to conflicts or choice of law.  You and the Company submit to the exclusive personal jurisdiction of the federal and state courts located in California in connection with any Dispute or any claim related to any Dispute.  By signing this Agreement, you acknowledge and agree that you will no longer be eligible for any benefits or payments provided for in any such prior agreement, except as otherwise expressly provided in this Agreement.

11.                               Successors and Assignment.

(a)                                 Company’s Successors.  Any successor to the Company (whether direct or indirect and whether by purchase, lease, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets will assume the obligations under

6

this Agreement and agree expressly to perform the obligations under this Agreement in the same manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession.  For all purposes under this Agreement, the term “Company” shall include any such successor to the Company, or to the Company’s business and/or assets, that executes and delivers the assumption agreement described in this Section 11(a) or which becomes bound by the terms of this Agreement by operation of law.

(b)                                 Employee’s Successors.  The terms of this Agreement and all of your rights hereunder will inure to the benefit of, and be enforceable by, your personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.  All of your obligations under this Agreement are personal to you and may not be transferred or assigned by you at any time.

“Board” means the Company’s Board of Directors.

A transaction will not constitute a Change in Control if its sole purpose is to change the state of the Company’s incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held the Company’s securities immediately before such transaction.  In addition, if a Change in Control constitutes a payment event with respect to any Equity Award which provides for a deferral of compensation and is subject to Section 409A of the Code, then notwithstanding anything to the contrary in this Agreement, the transaction with respect to such Equity Award must also constitute a “change in control event” as defined in Treasury Regulation 1.409A-3(i)(5) to the extent required by Section 409A of the Code.

ii.                                       A reduction in your base salary in effect immediately prior to such reduction;

v.                                      The Company’s breach of this Agreement, including its failure to obtain the assumption of this Agreement by any successor (whether direct or indirect and whether by purchase, merger, consolidation, liquidation or otherwise) to all or substantially all of the Company’s business and/or assets.

A Resignation for Good Reason will not be deemed to have occurred unless you give the Company written notice of the condition within ninety (90) days after the condition initially comes into existence and the Company fails to remedy the condition within thirty (30) days after receiving your written notice.
