Section 6. Incentive Opportunity

The CEO will determine, and recommend for approval by the Committee, incentive opportunities for each Participant. The incentive opportunities will be defined as Incentive Opportunity Zones that represent a range of threshold, target and maximum performance outcomes for which incremental increases in performance will result in incremental increases in the Incentive Award.

Each Incentive Opportunity Zone will include threshold, target and maximum incentive opportunities. The Participant’s target incentive opportunity will be based on the Participant’s role and responsibilities, and will be expressed as a percentage of the Participant’s base salary. The Participant’s threshold and maximum incentive opportunities will be expressed as a Payout Multiple of the target incentive opportunity and will also be based on the Participant’s role and responsibilities. The tables set forth on Exhibit A outline the target Payout Multiples for certain Participant categories.

The target incentive opportunity as a multiple of base salary, and the resulting threshold and maximum opportunities will be determined and approved in writing and kept on file for each Participant in the Business Support department.

Section 7. Performance Goals

Each Participant shall have specific performance goals (the “Performance Goals”) determined for his or her position for the Plan Year. These Performance Goals will be based on certain financial and nonfinancial performance measures that support the approved business plan of the Company and/or business unit, and should identify how the Participant will support the achievement of such goals.

Two performance categories will generally be used for each Participant:

The Performance Goals for these financial measures will generally be based on the Company’s 2016 financial budget/forecasts as approved by the Board.

The target mix and weighting of the Performance Goals for each Participant will vary depending on the Participant’s role and responsibilities, as set forth on Exhibit B .

2016 EMT Annual Incentive Plan

For the financial performance measures, threshold, target, and maximum Performance Goals will be established and aligned within the Participant’s applicable Incentive Opportunity Zone as defined above in Section 6. The threshold, target, and maximum Performance Goals for these financial measures, based on the Company’s budget/forecast for 2016 are set forth on Exhibit C .

The threshold, target and maximum individual Performance Goals will be based on how well the Participant met the goals established using the Company’s annual performance management system. The Individual Performance Goals will be aligned within the Participant’s applicable Incentive Opportunity Zone. While the interpretation of how well the Individual Performance Goals are met will be more subjective than for financial measures, the following descriptions will be used to interpret individual performance:

The target Incentive Opportunity Curve for each of the Performance Goals are set forth on Exhibit D .

At Plan Year-end, the following steps will occur to calculate each Participant’s final Incentive Award:

RESTRICTED STOCK UNITS AGREEMENT

(2013 Long-Term Incentive Plan)

This Restricted Stock Units Agreement (“Agreement”) is made effective as of                      (“ Grant Date ”), between CROWN CASTLE INTERNATIONAL CORP . (“ Company ”), a Delaware corporation, and                          (“ Holder ”).

Holder has been serving as an employee of the Company or one of its Affiliates. In recognition of service and in order to encourage Holder to remain with the Company or its Affiliates (the “ Group ”) and devote Holder’s best efforts to the Group’s affairs, thereby advancing the interests of the Company and its stockholders, the Company and Holder agree as follows:

1. Issuance of Restricted Stock Units . Upon the execution and return of this Agreement and for consideration from Holder to the Company in the form of services to the Group, the fair market value of which is at least equal to $.01 per each restricted stock unit granted pursuant to the 2013 Plan (defined below) (“ Unit ”) which may be issued hereunder, the Company shall grant to Holder                      Units (“ Holder’s Units ”), with each such Unit representing the right to potentially receive one share of $.01 par value Common Stock of the Company (“ Stock ”), subject to all of the terms set forth in this Agreement and in the Crown Castle International Corp. 2013 Long-Term Incentive Plan, as may be amended from time to time (“ 2013 Plan ”), which is incorporated herein by reference as a part of this Agreement. The terms “ Affiliate ,” “ Committee ”, “ Code ”, and “ Dividend Equivalent ” shall have the meanings assigned to them in the 2013 Plan.

2. Limitations on Rights Associated with Units and Dividend Equivalents . The Units and Dividend Equivalents granted pursuant to this Agreement are bookkeeping entries only. The Holder as to the Units shall have no rights as a stockholder of the Company, including no dividend rights (other than those described in Section 7 hereof with regard to Dividend Equivalents) and no voting rights.

3. Transfer and Forfeiture Restrictions . The Holder’s Units shall not be sold, assigned, pledged, or otherwise transferred except as provided herein (including the 2013 Plan), and Holder shall be obligated to forfeit and surrender, without further consideration from the Company, such Units (to the extent then subject to the Forfeiture Restrictions) to the Company in accordance with this Agreement. The obligation to forfeit and surrender Units to the Company is referred to herein as the “ Forfeiture Restrictions .” The transfer restrictions and Forfeiture Restrictions shall be binding upon and enforceable against any permitted transferee of Units.

4. Time Measures . [The following or other relevant vesting terms to be included as applicable to the specific award] (a) Except as otherwise provided in Section 5 hereof, the lapsing of the Forfeiture Restrictions on Holder’s Units shall be contingent upon meeting the applicable time measure (“ Time Measure ”) described below while Holder is an employee or a member of the board of directors (or a similar position) of a member of the Group.

-1-

(b) The Time Measure date is the date indicated below with the percentage beside such date being the percentage of the Holder’s Units no longer subject to the Forfeiture Restrictions as indicated.

(c) As soon as administratively feasible after a Time Measure is satisfied, (1) the Committee shall certify in writing that the applicable Time Measure has been satisfied and the Forfeiture Restrictions shall lapse as to the number of Holder’s Units as calculated above (“ Vested Units ”), and (2) the Company shall distribute to the Holder one share of Stock (“ Distributed Stock ”) in exchange for each Vested Unit in accordance with the timing restrictions of Section 9 hereof, and upon such exchange the Vested Units shall be automatically cancelled. The period from the Grant Date to the date that the applicable Time Measure is satisfied is sometimes hereinafter called the “ Restricted Period .”

(d) Any Holder’s Units with respect to which Forfeiture Restrictions cannot lapse pursuant to this Section 4 (including any exceptions pursuant to Section 5 hereof) shall be forfeited and surrendered to the Company by Holder.

5. Termination of Employment of Service . If Holder’s employment with the Group terminates or is terminated prior to the end of the last Restricted Period, then the remaining Holder’s Units shall be forfeited and surrendered to the Company; provided, however, that, in such event, the Committee may (subject to the terms of the 2013 Plan), in its sole discretion, cause the Forfeiture Restrictions to lapse as to all or a part of the Holder’s Units and, subject to the timing restrictions of Section 9 hereof, cause Distributed Stock to be issued and distributed with respect to such Units as if they were Vested Units subject to such terms set by the Committee, which may include satisfaction of the Time Measures that would otherwise be applicable to such Units if Holder’s employment with the Group had continued. For purposes of this Section 5, Holder’s services as a member of the board of directors (or a similar position) of a member of the Group shall be considered employment with the Group. In the event Holder’s employment with the Group terminates or is terminated under circumstances constituting retirement under any then-existing Board-approved retirement policy, the lapse of the Forfeiture Restrictions with respect to or the forfeiture of Holder’s Units, as applicable, shall be determined in accordance with such retirement policy.

6. Disclosure of Units . If Holder discloses or discusses in any manner this Agreement prior to the end of the Restricted Period to or with any other person (including any other employee of the Group), then the Holder’s Units may be forfeited and the Holder’s Units may be surrendered to the Company; provided, the above restriction is not applicable to the extent of reasonable disclosure (i) to an advisor to the Holder (e.g., accountant, financial planner) that has a legitimate reason to have such

-2-

information and that is subject to an obligation to maintain the confidentiality of such information, (ii) required by applicable law including any applicable securities law, (iii) to an employee of the Group specifically involved with the administration of this Agreement, or (iv) to Holder’s spouse.

7. Dividend Equivalents . While the Holder’s Units are outstanding and still subject to a Forfeiture Restriction, the Company will accrue Dividend Equivalents on behalf of the Holder. The Dividend Equivalents with respect to each Holder’s Unit will be equal to the sum of the cash dividends declared and paid by the Company with respect to each share of Stock while the Holder’s Units are outstanding. No interest will accrue on the Dividend Equivalents. The Dividend Equivalents with respect to a Holder’s Unit shall be earned and distributed in cash generally at or shortly after the time such Holder’s Unit converts to Stock and in accordance with Section 9 hereof. Any and all Dividend Equivalents with respect to the Holder’s Units that are forfeited shall also be forfeited and not deemed earned by nor distributed to Holder. Following lapsing of the Forfeiture Restrictions with respect to Holder’s Units and pending distribution of Distributed Stock in respect thereto, Holder shall be entitled to receive Dividend Equivalents relating to such Holder’s Units to the extent, if any, that the Holder is not entitled to receive with respect to the Distributed Stock dividends which would otherwise be paid to Holder during such interim period if the Distributed Stock had been so distributed, but in no event shall Holder be entitled to receive both a Dividend Equivalent and a dividend for such interim period.

8. Community Interest of Spouse . The community interest, if any, of any spouse of Holder in any of the Holder’s Units, Dividend Equivalents, and Distributed Stock shall be subject to all the terms of this Agreement, and shall be forfeited and surrendered to the Company upon the occurrence of any of the events requiring Holder’s interest in such Holder’s Units or Dividend Equivalents to be so forfeited and surrendered pursuant to this Agreement.

9. Internal Revenue Code §409A Compliance . Any Distributed Stock or Dividend Equivalents that become deliverable or payable to the Holder hereunder shall be delivered to the Holder no later than the end of the calendar year in which the Termination Date occurs. Notwithstanding the foregoing, in the event of a deemed lapse of any Forfeiture Restriction under the provisions of Section 5, delivery of Distributed Stock and Dividend Equivalents shall be made no earlier than the Termination Date otherwise applicable hereunder, and not later than the last day of the calendar year containing the Termination Date. This Agreement is intended to satisfy the requirement of Section 409A of the Internal Revenue Code of 1986, as amended, and the rules and regulations thereunder, and shall be interpreted consistent with such intent.

10. Withholding of Tax . To the extent that the Holder’s Units, Distributed Stock, Dividend Equivalents, or any event pursuant to this Agreement results in the receipt of compensation or other taxable income by Holder (including Holder’s Spouse) for tax purposes, Holder shall deliver to the Company such amount of cash or shares of Distributed Stock as the Company may require to meet its obligation under applicable

-3-

tax laws or regulations. The Company has the right to withhold shares of Distributed Stock or cash until Holder has made arrangements approved by the Company to satisfy all applicable tax withholding requirements of the Company.

11. Binding Effect . This Agreement shall be binding upon and inure to the benefit of any successors to the Company and all persons lawfully claiming under Holder.

12. Contract Terms . Notwithstanding the terms of this Agreement, if the Holder has entered into a separate written agreement with the Company which specifically affects the Units issued hereunder, the terms of such separate agreement shall control over any inconsistent terms of this Agreement.

13. Modification . Any modification of this Agreement will be effective only if it is in writing and signed by each party whose rights hereunder are affected thereby, except to the extent that such modification occurs pursuant to Section XIII of the 2013 Plan or as a result of an amendment of the 2013 Plan made in accordance with Section XIV of the 2013 Plan.

14. Governing Law .  This Agreement shall be governed by, and construed in accordance with, the laws of the State of Texas, without regard to conflicts of laws principles thereof.

15. Interpretation . Unless otherwise specified or the context otherwise requires, as used herein, (1) the term “including”, and any variation thereof, means “including, without limitation,” (2) the word “or” shall not be exclusive, and (3) a reference to the “terms” of an agreement, instrument or document or “terms” established by the Committee shall be a reference to “terms, provisions, conditions and restrictions.”

7

following the six (6) month anniversary of the Date of Termination (“ 409A Deferred Date ”) (or, if earlier, the date of Executive’s death) if the Executive is a “specified employee” pursuant to Section 409A of the Code. Notwithstanding anything to the contrary in Sections 4.1(b) and 4.2(b), with respect to the taxable amounts payable by the Company for the time period after Executive would be entitled to continuation coverage under a Company group health plan under Section 4980B of the Code if the Executive elected such coverage and paid the applicable premiums, Executive shall pay the monthly cost of the benefits consistent with the Company’s then current practices and the Company shall reimburse the Executive within 30 days after the Executive’s payment. Any reimbursements provided during an Executive’s taxable year shall not affect the amount eligible for reimbursement in any other taxable year and the right to premium reimbursement shall not be subject to liquidation or exchange for another payment or benefit. Notwithstanding anything to the contrary in Section 6.2, a payment pursuant to Section 6.2 shall be made (i) on or after the 409A Deferred Date if such payment is conditioned upon separation from service, (ii) on a monthly basis as to legal reimbursement, payable on the first (1st) day of each month (subject to (i) above), (iii) no later than the end of the taxable year of the Executive (or his estate), as applicable, following the taxable year in which a reimbursable expense was incurred (subject to (i) above), and (iv) no later than the end of the third (3rd) anniversary of the Executive’s death.

(b) Any payment or benefit that otherwise would be paid or provided following the Date of Termination and that is subject to deferral pursuant to Section 4.6(a) shall be accumulated and paid in a lump sum at the earliest date which complies with the requirements of Section 409A. This Section 4.6 and the Agreement shall be interpreted and construed consistent with Section 409A and concomitant regulations in order to avoid the imposition of any additional taxes and interest pursuant to Section 409A (“ 409A Taxes ”).”

The Executive shall be subject to the following noncompetition obligations:

(a) As consideration for the Agreement as provided herein, the Company and the Executive agree to the noncompetition obligations hereunder. From the Commencement Date and continuing for a period of 12 months from the Date of Termination, the Executive shall not personally engage in any “Competitive Activities” (as defined below) within any geographic area in the United States or Australia in which the Company or any of its Affiliates is then engaged in Competitive Activities (“ Restricted Areas ”); including, without limitation, working for, owning, managing, operating, controlling or participating in the ownership, management, operation or control of, or providing consulting or advisory services to, any individual partnership, firm, corporation, institution, entity or other person (“ person ”) engaged in Competitive Activities within any Restricted Areas; provided, however, that the purchase or holding for investment

8

purposes only, of securities of a company shall not constitute “ownership” or “participation in ownership” for these purposes so long as the equity interest in any such company represents less than 5% of the outstanding capital stock of such company. Anything herein to the contrary notwithstanding, no person shall be deemed engaged in Competitive Activities if less than 5% of its revenues are derived from “Competitive Activities” as defined in the next paragraph.

For such purposes above, “ Competitive Activities ” mean any business activity involving or relating to owning or operating wireless communication or broadcast towers located in the Restricted Area; provided, however, that if the Company is advised of a business opportunity by the Executive as provided below, and it declines to pursue such business opportunity, the Executive shall be free to pursue such business opportunity and such activity shall not be a “Competitive Activity.” If after the Date of Termination the Executive becomes aware of a business opportunity which involves a Competitive Activity in the Restricted Area, the Executive shall fully advise (in writing and indicating that such information is pursuant to this provision) the Company as to such opportunity and will not pursue it except as provided herein. If, within 15 business days of the Executive’s advising the Company of such business opportunity, the Board fails to adopt a resolution (and provide a certified copy to the Executive) that it will pursue such business opportunity, the Company will be deemed to have declined to pursue such opportunity. If, after a vote by the Board in favor of pursuing a business opportunity, the Company “fails to pursue” such opportunity, then the Company, including for this purpose the Board, shall be deemed to have declined to pursue such business opportunity as of the date it “fails to pursue” such opportunity. “ Fails to pursue ” means that the Company has failed to pursue such opportunity in a reasonable commercial manner and “fails to pursue” is irrebutably presumed if (x) within 30 days of such vote, the Company has not signed a confidentiality agreement with the parties representing such business opportunity; (y) within 60 days of such vote, the Company has not begun the due diligence process regarding such business opportunity; or (z) within 120 days of such vote, the Company is not in active discussions, or has otherwise terminated its discussions with the parties representing such business opportunity.

Notwithstanding anything to the contrary in this Section V(a), activities shall not be deemed to be “Competitive Activities” solely as a result of the Executive’s being employed by or otherwise associated with a business of which a unit is in competition with the Company but as to which unit Executive does not have direct or indirect responsibility or direct involvement.

For purposes of this Agreement, “ Affiliate ” of a specified person means a person that directly or indirectly controls, is controlled by, or is under common control with the person specified.

(b) For a period of 12 months from the Date of Termination, the Executive shall not knowingly induce any employee of the Company or any of its Affiliates to terminate his or her employment with the Company or any of the Affiliates to work with or for the Executive or any of Executive’s future employers and provided further that the Executive’s response to unsolicited requests for employment references for employees of the Company shall not be a violation of this restriction.

9

(c) The Executive understands that the restrictions set forth in (a) and (b) above may limit the Executive’s ability to engage in certain businesses in the Restricted Areas during the 12-month period provided for in (a) and (b) above, but acknowledges that the Executive will receive sufficiently high remuneration and other benefits under this Agreement to justify such restrictions. The Executive acknowledges that money damages would not be sufficient remedy for any breach of the provisions of (a) and (b) above by the Executive, and the Company shall be entitled to enforce such provisions by specific performance and injunctive relief as remedies for such breach or any threatened breach. Such remedies shall not be deemed the exclusive remedies for such breach, but shall be in addition to all remedies available at law or in equity to the Company, including without limitation, the recovery of damages from the Executive and the Executive’s agents involved in such breach and remedies available to the Company pursuant to other agreements with the Executive. Notwithstanding the foregoing, in the event that the Executive and/or the Executive’s agents breach the restrictions set forth in clauses (a) and/or (b), the Company shall in no circumstances be entitled to recover damages or other compensation in respect of all such breaches in excess of fifty percent (50%) of the amount paid to Executive pursuant to Section 4.1(a)(ii) or 4.2(a)(ii), as applicable.

(d) It is expressly understood and agreed that the Company and the Executive consider the restrictions contained in (a) and (b) above to be reasonable and necessary to protect the business of the Company. Nevertheless, if any of the aforesaid restrictions are found by an arbitrator or a court having jurisdiction to be unreasonable, or overly broad as to geographic area or time, or otherwise unenforceable, the parties intend for the restrictions therein set forth to be modified by such arbitrator or court so as to be reasonable and enforceable and, as so modified by such arbitrator or court, to be fully enforced.

6.1 Non-exclusivity of Rights . Nothing in this Agreement shall prevent or limit the Executive’s continuing or future participation in any benefit, bonus, incentive or other Plan provided by the Company or any of its Affiliates and for which the Executive may qualify (including, without limitation, any insurance benefits relating to death or Disability of the Executive), nor shall anything herein limit or otherwise affect such rights as the Executive may have under any other agreements with the Company or any of its Affiliates; provided that, by executing this Agreement, the Executive acknowledges Executive’s ineligibility for, and waives any other right Executive may have to receive, any other severance or termination benefits provided by the Company or its subsidiaries. Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any Plan of the Company or any of its Affiliates (other than any severance plan or program of the Company and its subsidiaries) at or subsequent to the Date of Termination shall be payable in accordance with such Plan except as explicitly modified by this Agreement.

6.2 Other Payments and Obligations . The Company’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the Company may have against the Executive or others.

10

In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement. The Company agrees to pay, from time to time promptly upon invoice, to the full extent permitted by law, all legal fees and expenses which the Executive may reasonably incur as a result of any contest or controversy (regardless of the outcome thereof and whether or not litigation is involved) by the Company, the Executive or others of the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof; provided any contest or dispute is not in bad faith by the Executive.

6.3 Confidential Information .

(a) During the Term and thereafter, the Executive shall not, without the written consent of the Chief Executive Officer of the Company (“ CEO ”) or the Board (including an applicable committee of the Board) disclose to any person, other than (i) an employee of the Company, (ii) a person to whom disclosure is reasonably necessary or appropriate in connection with the performance by the Executive of Executive’s duties as an executive of the Company, (iii) to the extent required by applicable law (including any rule or regulation) or (iv) to the extent necessary to enforce Executive’s rights pursuant to this Agreement, any material confidential information obtained by Executive while in the employ of the Company or its subsidiaries with respect to any of the products, improvements, formulas, designs or styles, processes, customers, methods of distribution or methods of manufacture of the Company or its subsidiaries, the disclosure of which Executive knows will be materially damaging to the Company; provided, however, that confidential information shall not include any information known generally to the public (other than as a result of unauthorized disclosure by the Executive) or any information of a type not otherwise considered confidential by persons engaged in the same business or a business similar to that conducted by the Company. Information concerning a business opportunity described in Section V (a) which the Company declines or “fails to pursue” shall not constitute information for purposes of this section.

(b) Any and all inventions made, developed or created by the Executive (whether at the request or suggestion of the Company or otherwise, whether alone or in conjunction with others, and whether during regular hours of work or otherwise) during the period of Executive’s employment by the Company or its subsidiaries, which may be directly or indirectly useful in, or relate to, the business of or tests being carried out by the Company or any of its subsidiaries, will be promptly and fully disclosed by the Executive to an appropriate executive officer of the Company and shall be the Company’s exclusive property as against the Executive, and the Executive will promptly deliver to an appropriate executive officer of the Company all papers, drawings, models, data and other material relating to any invention made, developed or created by Executive as aforesaid.

(c) The Executive will, upon the Company’s request and without any payment therefor, execute any documents necessary or advisable in the opinion of the Company’s counsel to direct issuance of patents to the Company with respect to such inventions as are to be the Company’s exclusive property as against the

11

Executive under Section 6.3 (b) above or to vest in the Company title to such inventions as against the Executive; provided, however, that the expense of securing any such patent will be borne by the Company.

(d) The foregoing provisions of this Section 6.3 shall be binding upon the Executive’s heirs, successors and legal representatives.

(e) In no event shall an asserted violation of the provisions of this Section 6.3 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement.

6.4 Release and Agreement . As a condition to the receipt of any compensation and benefits under this Agreement, if the Executive’s employment with the Company is subject to a Qualifying Termination, the Executive must first execute a release and agreement (“ Release ”), in a reasonable commercial form, which shall release the Company and its subsidiaries and their officers, directors, employees and agents from any and all claims or causes of action arising out of the Executive’s employment with the Company or its subsidiaries on the termination of such employment and thereafter not revoke the Release. Notwithstanding any provision herein to the contrary, if Executive has not delivered to the Company the executed Release on or before the 170th day after the Date of Termination, Executive shall forfeit all payments and benefits payable under Section 4.1 or 4.2 (other than Accrued Obligations), as applicable; provided however, that Executive shall not forfeit such amounts and benefits if (i) the Company has not delivered to Executive the required Release on or before the 30th day following the Date of Termination or (ii) such requirement is not necessary to avoid 409A Taxes. If a payment or benefit could otherwise be paid or provided in different calendar years as a result of the Release requirements, such payment shall be paid or provided in the later calendar year. The performance of the Company’s obligation herein and the receipt of the payments and benefits provided herein to the Executive shall constitute full settlement of all such claims and causes of action and shall provide consideration for the Release.

6.5 Indemnification; D&O Coverage

(a) If the Executive is made a party, is threatened to be made a party, or reasonably anticipates being made a party, to any Proceeding by reason of the fact that Executive is or was a director, officer, member, employee, agent, manager, trustee, consultant or representative (“ Agent ”) of the Company or any of its Affiliates or is or was serving at the request of the Company or any of its Affiliates, as an Agent of another person or if any Claim is made, is threatened to be made, or is reasonably anticipated to be made, that arises out of or relates to the Executive’s service in any of the foregoing capacities, then the Executive shall promptly notify the Company in writing and be indemnified and held harmless to the fullest extent permitted or authorized by the Certificate of Incorporation or Bylaws of the Company as in effect on the Date of Termination (subject to any limitations imposed by applicable law), against any and all costs, expenses, liabilities and losses (including, without limitation, reasonable attorneys’ and other professional fees and charges, judgments, interest, expenses of investigation, penalties, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) incurred or suffered by the Executive in connection therewith or in

12

connection with seeking to enforce Executive’s rights under this Section 6.5(a), and such indemnification shall continue as to the Executive even if Executive has ceased to be an Agent of the Company or other person and shall inure to the benefit of the Executive’s heirs, executors and administrators. The failure to give prompt notice shall only reduce the indemnification obligation to the extent, if any, that the Company is damaged by such breach. The Executive shall be entitled to prompt advancement of any and all costs and expenses (including, without limitation, reasonable attorneys’ and other professional fees and charges) incurred by Executive in connection with any such Proceeding or Claim to the fullest extent permitted or authorized by the Certificate of Incorporation or Bylaws of the Company as in effect on the Date of Termination (subject to any limitations imposed by applicable law), any such advancement to be made promptly after Executive gives written notice, supported by reasonable documentation, requesting such advancement. Such notice shall include, to the extent required by applicable law, an undertaking by the Executive to repay the amounts advanced to the extent that Executive is ultimately determined not to be entitled to indemnification against such costs and expenses. Nothing in this Agreement shall operate to limit or extinguish any right to indemnification, advancement of expenses, or contribution that the Executive would otherwise have (including, without limitation, by agreement or under applicable law). For purposes of this Agreement, “ Claim ” shall include, without limitation, any claim, demand, request, investigation, dispute, controversy, threat, discovery request, or request for testimony or information and “ Proceeding ” shall include, without limitation, any actual, threatened, or reasonably anticipated, action, suit or proceeding, whether civil, criminal, administrative, investigative, appellate, formal, informal or other.

(b) Neither the failure of the Company (including its Board, independent legal counsel or stockholders) to have made a determination prior to the commencement of any Proceeding concerning payment of amounts claimed by the Executive under Section 6.5(a) that indemnification of the Executive is proper because Executive has met the applicable standard of conduct, nor a determination by the Company (including its Board, independent legal counsel or stockholders) that the Executive has not met such applicable standard of conduct, shall create a presumption that the Executive has not met the applicable standard of conduct.

(c) A directors’ and officers’ liability insurance policy (or policies) shall be kept in place until the sixth anniversary of the Date of Termination, providing coverage to the Executive that is no less favorable to Executive in any respect (including with respect to scope, exclusions, amounts, and deductibles) than the coverage then being provided to any other present or former senior executive or director of the Company.

6.6 Successors .

(a) This Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable by the Executive otherwise than by will or the laws of descent and distribution.

A violation or threatened violation of any of the above prohibitions may be enjoined by any court with jurisdiction. The rights afforded under this provision are in addition to any and all rights otherwise afforded by applicable law. Nothing shall prevent the Executive or the Company from truthfully and publicly correcting incorrect statements or from making truthful disclosures to the extent required (i) by law, by a government agency having supervisory authority over the business of the Company or any of its Affiliates or by any arbitrator, mediator or administrative or legislative body (including a committee thereof) with apparent jurisdiction or (ii) to enforce this Agreement.

6.8 Notices . All notices and other communications hereunder shall be in writing and shall be given by (i) personal delivery, (ii) registered or certified mail, return receipt requested, postage prepaid, addressed as indicated below or (iii) nationally recognized overnight courier, with written confirmation of receipt, addressed as indicated below:

6.12 Waiver . The Executive’s failure to insist upon strict compliance with any provision hereof shall not be deemed to be a waiver of such provision or any other provision thereof.

Notwithstanding anything to the contrary in Sections 4.1 (b) and 4.2(b) with respect to the taxable amounts payable by the Company for the time period after Executive would be entitled to continuation coverage under a Company group health plan under Section 4980B of the Code if the Executive elected such coverage and paid the applicable premiums, Executive shall pay the monthly cost of the benefits consistent with the Company’s then current practices and the Company shall reimburse the Executive within 30 days after the Executive’s payment.

This Section 4.6 and the Agreement shall be interpreted and construed consistent with Section 409A and concomitant regulations in order to avoid the imposition of any additional taxes and interest pursuant to Section 409A (“ 409A Taxes ”).”

The Executive shall be subject to the following noncompetition obligations:

(a) As consideration for the Agreement as provided herein, the Company and the Executive agree to the noncompetition obligations hereunder. From the Commencement Date and continuing for a period of 12 months from the Date of Termination, the Executive shall not personally engage in any “Competitive Activities” (as defined below) within any geographic area in the United States, the United Kingdom or Australia in which the Company or any of its Affiliates is then engaged in Competitive Activities (“ Restricted Areas ”); including, without limitation, working for, owning, managing, operating, controlling or participating in the ownership, management, operation or control of, or providing consulting or advisory services to, any individual partnership, firm, corporation, institution, entity or other person (“ person ”) engaged in Competitive

8

Activities within any Restricted Areas; provided, however, that the purchase or holding for investment purposes only, of securities of a company shall not constitute “ownership” or “participation in ownership” for these purposes so long as the equity interest in any such company represents less than 5% of the outstanding capital stock of such company. Anything herein to the contrary notwithstanding, no person shall be deemed engaged in Competitive Activities if less than 5% of its revenues are derived from “Competitive Activities” as defined in the next paragraph.

For such purposes above, “ Competitive Activities ” mean any business activity involving or relating to owning or operating wireless communication or broadcast towers located in the Restricted Area; provided, however, that if the Company is advised of a business opportunity by the Executive as provided below, and it declines to pursue such business opportunity, the Executive shall be free to pursue such business opportunity and such activity shall not be a “Competitive Activity.” If after the Date of Termination the Executive becomes aware of a business opportunity which involves a Competitive Activity in the Restricted Area, the Executive shall fully advise (in writing and indicating that such information is pursuant to this provision) the Company as to such opportunity and will not pursue it except as provided herein. If, within 15 business days of the Executive’s advising the Company of such business opportunity, the Board fails to adopt a resolution (and provide a certified copy to the Executive) that it will pursue such business opportunity, the Company will be deemed to have declined to pursue such opportunity. If, after a vote by the Board in favor of pursuing a business opportunity, the Company “fails to pursue” such opportunity, then the Company, including for this purpose the Board, shall be deemed to have declined to pursue such business opportunity as of the date it “fails to pursue” such opportunity. “ Fails to pursue ” means that the Company has failed to pursue such opportunity in a reasonable commercial manner and “fails to pursue” is irrebutably presumed if (x) within 30 days of such vote, the Company has not signed a confidentiality agreement with the parties representing such business opportunity; (y) within 60 days of such vote, the Company has not begun the due diligence process regarding such business opportunity; or (z) within 120 days of such vote, the Company is not in active discussions, or has otherwise terminated its discussions with the parties representing such business opportunity.

Notwithstanding anything to the contrary in this Section V(a), activities shall not be deemed to be “Competitive Activities” solely as a result of the Executive’s being employed by or otherwise associated with a business of which a unit is in competition with the Company but as to which unit Executive does not have direct or indirect responsibility or direct involvement.

For purposes of this Agreement, “ Affiliate ” of a specified person means a person that directly or indirectly controls, is controlled by, or is under common control with the person specified.

(b) For a period of 12 months from the Date of Termination, the Executive shall not knowingly induce any employee of the Company or any of its Affiliates to terminate his or her employment with the Company or any of the Affiliates to work with or for the Executive or any of Executive’s future employers and provided further that the Executive’s response to unsolicited requests for employment references for employees of the Company shall not be a violation of this restriction.

9

(c) The Executive understands that the restrictions set forth in (a) and (b) above may limit the Executive’s ability to engage in certain businesses in the Restricted Areas during the 12-month period provided for in (a) and (b) above, but acknowledges that the Executive will receive sufficiently high remuneration and other benefits under this Agreement to justify such restrictions. The Executive acknowledges that money damages would not be sufficient remedy for any breach of the provisions of (a) and (b) above by the Executive, and the Company shall be entitled to enforce such provisions by specific performance and injunctive relief as remedies for such breach or any threatened breach. Such remedies shall not be deemed the exclusive remedies for such breach, but shall be in addition to all remedies available at law or in equity to the Company, including without limitation, the recovery of damages from the Executive and the Executive’s agents involved in such breach and remedies available to the Company pursuant to other agreements with the Executive. Notwithstanding the foregoing, in the event that the Executive and/or the Executive’s agents breach the restrictions set forth in clauses (a) and/or (b), the Company shall in no circumstances be entitled to recover damages or other compensation in respect of all such breaches in excess of the amount paid to Executive pursuant to Section 4.1(a)(ii) or 4.2(a)(ii), as applicable, reduced by an amount equal to the Executive’s Base Salary and Annual Bonus.

(d) It is expressly understood and agreed that the Company and the Executive consider the restrictions contained in (a) and (b) above to be reasonable and necessary to protect the business of the Company. Nevertheless, if any of the aforesaid restrictions are found by an arbitrator or a court having jurisdiction to be unreasonable, or overly broad as to geographic area or time, or otherwise unenforceable, the parties intend for the restrictions therein set forth to be modified by such arbitrator or court so as to be reasonable and enforceable and, as so modified by such arbitrator or court, to be fully enforced.

6.1 Non-exclusivity of Rights . Nothing in this Agreement shall prevent or limit the Executive’s continuing or future participation in any benefit, bonus, incentive or other Plan provided by the Company or any of its Affiliates and for which the Executive may qualify (including, without limitation, any insurance benefits relating to death or Disability of the Executive), nor shall anything herein limit or otherwise affect such rights as the Executive may have under any other agreements with the Company or any of its Affiliates ; provided that, by executing this Agreement, the Executive acknowledges Executive’s ineligibility for, and waives any other right Executive may have to receive, any other severance or termination benefits provided by the Company or its subsidiaries. Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any Plan of the Company or any of its Affiliates (other than any severance plan or program of the Company and its subsidiaries) at or subsequent to the Date of Termination shall be payable in accordance with such Plan except as explicitly modified by this Agreement.

6.2 Other Payments and Obligations . The Company’s obligation to make the payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or

10

other claim, right or action which the Company may have against the Executive or others. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the Executive under any of the provisions of this Agreement. The Company agrees to pay, from time to time promptly upon invoice, to the full extent permitted by law, all legal fees and expenses which the Executive may reasonably incur as a result of any contest or controversy (regardless of the outcome thereof and whether or not litigation is involved) by the Company, the Executive or others of the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof.

Information concerning a business opportunity described in Section V (a) which the Company declines or “fails to pursue” shall not constitute information for purposes of this section.

(b) Any and all inventions made, developed or created by the Executive (whether at the request or suggestion of the Company or otherwise, whether alone or in conjunction with others, and whether during regular hours of work or otherwise) during the period of Executive’s employment by the Company or its subsidiaries, which may be directly or indirectly useful in, or relate to, the business of or tests being carried out by the Company or any of its subsidiaries, will be promptly and fully disclosed by the Executive to an appropriate executive officer of the Company and shall be the Company’s exclusive property as against the Executive, and the Executive will promptly deliver to an appropriate executive officer of the Company all papers, drawings, models, data and other material relating to any invention made, developed or created by Executive as aforesaid.

(d) The foregoing provisions of this Section 6.3 shall be binding upon the Executive’s heirs, successors and legal representatives.

(e) In no event shall an asserted violation of the provisions of this Section 6.3 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement.

6.4 Release and Agreement . As a condition to the receipt of any compensation and benefits under this Agreement, if the Executive’s employment with the Company is subject to a Qualifying Termination, the Executive must first execute a release and agreement (“ Release ”), in a reasonable commercial form, which shall release the Company and its subsidiaries and their officers, directors, employees and agents from any and all claims or causes of action arising out of the Executive’s employment with the Company or its subsidiaries on the termination of such employment and thereafter not revoke the Release.

If a payment or benefit could otherwise be paid or provided in different calendar years as a result of the Release requirements, such payment shall be paid or provided in the later calendar year. The performance of the Company’s obligation herein and the receipt ofthe payments and benefits provided herein to the Executive shall constitute full settlement of all such claims and causes of action and shall provide consideration for the Release.
