CHANGE IN CONTROL SEVERANCE AGREEMENT

This CHANGE IN CONTROL SEVERANCE AGREEMENT (this “Agreement”) is made as of the          day of                 , 200    , between Under Armour, Inc., a corporation organized under the laws of the State of Maryland (together with its affiliates, the “Company”), and                                          (“Executive”).

WITNESSETH THAT:

WHEREAS, should Under Armour, Inc. or shareholders of Under Armour, Inc. receive any proposal from a third person regarding a possible Change in Control, the Board of Directors of Under Armour, Inc. (the “Board”) believes it is important that the Company be able to rely upon the Executive to continue in his position until after such Change in Control and that Under Armour, Inc. be able to receive and rely upon the Executive’s advice, if requested, as to the best interest of Under Armour, Inc. and its shareholders in connection with any such Change in Control, without concern that the Executive might be distracted or his advice affected by the personal uncertainties and risks created by such a Change in Control.

NOW THEREFORE, in order to provide an incentive to the Executive for the continued dedication of Executive and the availability of his advice and counsel notwithstanding the possibility of a Change in Control, and to encourage Executive to remain in the employ of the Company, and for other good and valuable consideration, the Company and Executive hereby agree as follows:

3. Termination of Employment of Executive. The Executive’s employment may be terminated by following the procedures specified in this Section 3.

(i) Cause. The Executive may not be terminated for Cause unless and until a notice of intent to terminate the Executive’s employment for Cause, specifying the particulars of the conduct of the Executive forming the basis for such termination, is given to the Executive by the Company and, subsequently, a majority of the Board finds, after reasonable notice to the Executive (but in no event less than fifteen (15) days prior notice) and an opportunity for the Executive and his counsel to be heard by the Board, that termination of the Executive’s employment for Cause is justified. Termination of the Executive’s employment for Cause shall become effective after such finding has been made by the Board and five (5) business days after the Board gives to the Executive notice thereof, specifying in detail the particulars of the conduct of the Executive found by the Board to justify termination for Cause. It shall not constitute Good Reason to the Executive to the extent the Executive is relieved of any duties and responsibilities during the period the Board is considering whether such termination for Cause is justified.

(iii) Termination Without Cause. At all times, the Company shall have the right by notice to the Executive of the Company’s intention to terminate Executive’s employment Without Cause. Termination of Executive’s employment by the Company Without Cause shall become effective immediately upon the receipt by the Executive of such notice.

(iv) Voluntary Termination by the Executive. The Executive may terminate his employment with the Company by giving a notice of voluntary termination to the Company, and if such termination is for Good Reason, such notice shall set forth in reasonable detail the acts and circumstances claimed by the Executive to constitute Good Reason. Termination of the Executive’s employment by the Executive without Good Reason shall be effective five (5) business days after the Executive gives notice thereof to the Company. The Company shall have twenty (20) days after receipt of such notice from the Executive of claimed Good Reason to cure any Good Reason. If the Company is unable to cure the Good Reason during such cure period, termination of the Executive’s employment by the Executive for Good Reason shall be effective five (5) business days after the expiration of such cure period.

(v) Death. Termination of the Executive’s employment for death shall be effective on the date of the Executive’s death.

4. Benefits Upon Termination of Employment.

(i) Termination Without Cause or by the Executive for Good Reason. Upon the termination of the employment of Executive Without Cause by the Company or by the Executive for Good Reason, the Company shall pay or provide to the Executive:

(a) a lump sum payment equal to the sum of the following:

The payment described in this Section 4(i)(a) shall be made by the Company not later than the earlier of the date required by applicable law or five (5) days following the Termination Date. Executive shall not be required to mitigate the amount of the payment provided for in this Section 4(i)(a) by seeking other employment or otherwise. The amount of the payment provided for in this Section 4(i)(a) shall not be reduced by any compensation or other amounts paid to or earned by Executive as the result of employment with another employer after the date on which his employment with the Company terminates or otherwise.

(b) the continuance of the Executive’s life, medical, dental, prescription drug and long and short-term disability plans, programs or arrangements, whether group or individual, of the Company in which the Executive was entitled to participate at any time during the twelve (12) month period prior to the Termination Date until the earliest to occur of (1) one (1) year after the Termination Date; (2) the Executive’s death (provided that compensation and benefits payable to his beneficiaries shall not terminate upon his death); or (3) with respect to any particular plan, program or arrangement, the date the Executive is afforded a comparable benefit at a comparable cost to the Executive by a subsequent employer. In the event that the Executive’s participation in any such plan, program or arrangement of the Company is prohibited, the Company shall arrange to provide the Executive with compensation and benefits substantially similar to those which the Executive is entitled to receive under such plan, program or arrangement for such period.

Notwithstanding the foregoing, in the event the payments or benefits under this Section 4 would result in the imposition of a tax under Section 409A of the Code, then such payments or benefits will be paid or provided at such time when such payments or benefits would not be subject to such tax.

(ii) Cobra Continuation Coverage. Upon the expiration of the provision of benefits in Section 4(i)(b), the Executive and his dependents shall be entitled to exercise such rights as they may have under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”).

(vi) Conditions to Receiving Benefits. The benefits described in Sections 4(i)(a)(2) and 4(i)(b) shall be subject to the Executive’s execution of the Employee Confidentiality, Non-Competition, and Non-Solicitation Agreement attached hereto as Attachment A and the benefits described in Sections 4(i)(a)(2) and 4(i)(b) will not be paid to the Executive unless and until the Executive executes the release attached hereto as Attachment B, and such release becomes effective and irrevocable.

(vii) No Further Payments due to Executive. Except as provided in this Section 4, the Company shall have no obligation to make any other payment, in the nature of severance or termination pay.

(viii) Exception to Benefit Entitlements.

(viii) Retirement Payments. No amounts paid pursuant to this Agreement will constitute compensation for any purpose under any retirement plan or other employee benefit plan, program, arrangement or agreement of the Company or any of its affiliates, unless such plan, program, arrangement or agreement specifically so provides.

5. Successors; Binding Agreement.

(a) This Agreement shall be binding upon any successor (whether direct or indirect, by purchase, merger, consolidation, liquidation or otherwise) to all or substantially all of the business and/or assets of Under Armour, Inc. Additionally, Under Armour, Inc. shall require any such successor expressly to agree to assume and to assume of the obligations of the Company under this Agreement upon or prior to such succession taking place.

ATTACHMENT A

EMPLOYEE CONFIDENTIALITY, NON-COMPETITION, AND

NON-SOLICITATION AGREEMENT

This Confidentiality, Non-Competition, and Non-Solicitation Agreement (“Agreement”) is entered into this         day of                 , 2008, by and between Under Armour, Inc. (together with its affiliates, the “Company”) and                                          (“Employee”).

EXPLANATORY NOTE

The Employee recognizes that the Employee has had or will have access to confidential proprietary information during the course of his or her employment and that the Employee’s subsequent employment with a Competitor Business, as defined in Section 3, would inevitably result in the disclosure of that information and, thereby, create unfair competition and would likely cause substantial loss and harm to the Company. The Employee further acknowledges that employment with the Company is based on the Employee’s agreement to abide by the covenants contained herein.

NOW THEREFORE, in consideration of Employee’s employment with the Company and for other good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties agree as follows:

1. Confidentiality. Employee acknowledges Employee’s fiduciary duty and duty of loyalty to the Company. Further, Employee acknowledges that the Company, in reliance on this Agreement, will provide Employee access to trade secrets, customers, proprietary data and other confidential information. Employee agrees to retain said information as confidential and not to use said information for the Employee’s personal benefit or to disclose same to any third party, except when required to do so to properly perform duties to the Company. Further, as a condition of employment, during the time Employee is employed by the Company and continuing after any termination of the Employee’s employment with the Company, Employee agrees to protect and hold in a fiduciary capacity for the benefit of the Company all Confidential Information, as defined below, unless the Employee is required to disclose Confidential Information pursuant to the terms of a valid and effective order issued by a court of competent jurisdiction or a governmental authority. The Employee shall use Confidential Information solely for the purpose of carrying out those duties assigned Employee as an employee of the Company and not for any other purpose. The disclosure of Confidential Information to the Employee shall not be construed as granting to the Employee any license under any copyright, trade secret, or any right of ownership or right to use the Confidential Information whatsoever. In the event that Employee is compelled, pursuant to a subpoena or order of a court or other body having jurisdiction over such matter, to produce any Confidential Information or other information relevant to the Company, Employee agrees to promptly provide the Company with written notice of such subpoena or order so that the Company may timely move to quash if appropriate.

(a) For the purposes of this Agreement, “Confidential Information” shall mean all information related to the Company’s business that is not generally known to the public. Confidential Information shall include, but shall not be limited to: any financial (whether historical, projections or forecasts), pricing, cost, business, planning, operations, services, potential services, products, potential products, technical information, intellectual property, trade secrets and/or know-how, formulas, production, purchasing, marketing, sales, personnel, customer, supplier, or other information of the Company; any papers, data, records, processes, methods, techniques, systems, models, samples, devices, equipment, compilations, invoices, customer lists, or documents of the Company; any confidential information or trade secrets of any third party provided to the Company in confidence or subject to other use or disclosure restrictions or limitations; this Agreement and its terms; and any other information, written, oral or electronic, whether existing now or at some time in the future, whether pertaining to current or future developments or prospects, and whether accessed prior to the Employee’s tenure with the Company or to be accessed during Employee’s future employment or association with the Company, which pertains to the Company’s affairs or interests or with whom or how the Company does business. The Company acknowledges and agrees that Confidential Information shall not include information which is or becomes publicly available other than as a result of a disclosure by the Employee.

(b) The Employee shall promptly notify the Company if he or she has reason to believe that the unauthorized use, possession, or disclosure of any Confidential Information has occurred or may occur.

(c) All physical items containing Confidential Information, including, but not limited to, the business plan, know-how, collection methods and procedures, advertising techniques, marketing plans and methods, sales techniques, documentation, contracts, reports, letters, notes, any computer media, customer lists and all other information and materials of the Company’s business and operations, shall remain the exclusive and confidential property of the Company and shall be returned, along with any copies or notes that the Employee made thereof or therefrom, to the Company when the Employee ceases employment with the Company. The Employee further agrees to return copies of any Confidential Information contained on Employee’s home computer, portable computer or other similar device. Employee also agrees to allow the Company, upon reasonable notice and for just cause, access to any home computer, portable computer or other similar device maintained by Employee, including but not limited to, for the purpose of determining whether said Confidential Information has been misappropriated. The Employee further agrees to promptly return all other property belonging to the Company upon the termination of Employee’s employment.

2. Ownership of Works for Hire.

(a) The Employee agrees that any inventions, ideas, developments, methods, improvements, discoveries, innovations, software, works of authorship and any other intangible property (hereinafter collectively referred to as “Intellectual Property”), whether patentable or not, which are developed, partially developed, considered, contemplated or reduced to practice by the Employee or under his or her direction or jointly with others during his or her employment with the Company, whether or not

during normal working hours or on the premises of the Company, shall be considered “Works for Hire” for the exclusive use and benefit of the Company. The Employee will make full and prompt disclosure to the Company of all such Works for Hire. The Company shall own all rights to any Works for Hire, including all copyrights and the right to market (or not to market) any such property, and the Employee agrees to assign and does hereby assign to the Company (or any person or entity designated by the Company) all his or her right, title and interest in and to all Works for Hire and all related patents, patent applications, copyrights and copyright applications.

(b) The Employee agrees to cooperate fully with the Company, both during and after his or her employment with the Company, with respect to the procurement, maintenance and enforcement of copyrights and patents (both in the United States and foreign countries) relating to Works for Hire. The Employee shall sign all papers, including, without limitation, copyright applications, patent applications, declarations, oaths, formal assignments, assignment of priority rights, and powers of attorney, which the Company may deem necessary or desirable in order to protect its rights and interests in any Works for Hire.

(c) The Employee specifically acknowledges that his or her compensation and benefits constitute full payment for any Works for Hire and waives any claim of right to the Company.

(d) The Company may, at its election and discretion, waive and/or relinquish any of its rights of ownership and royalties with respect to any Works for Hire, by agreeing to do so in a written instrument executed by the Company.

3. Non-Competition. Except as otherwise provided in this Agreement, without the prior written consent of the Company, the Employee hereby covenants and agrees that at no time during the Employee’s employment with Company and for a period of one (1) year immediately following termination of Employee’s employment with the Company, whether voluntary or involuntary, shall the Employee:

(a) directly or indirectly work for or engage in any capacity in any activities or provide strategic advice to Competitor Businesses. Competitor Businesses shall be defined as (i) any business that is involved in the manufacture, sale, development of fabrications or manufacturing methods, or marketing of: athletic apparel or footwear (e.g., Reebok, Nike, Adidas); sporting goods; tactical (military and/or law enforcement) apparel; hunting and fishing apparel; mountain sports apparel; accessories of such industries; or any business substantially similar to the present business of the Company or such other business activity in which the Company may substantially engage; and (ii) retail enterprises which sell products that compete with the Company’s products;

(b) act in any way, directly or indirectly, with the purpose or effect of soliciting, diverting or taking away any business, customer, client or any supplier of the Company; or

(c) otherwise compete with Company in the sale or licensing, directly or indirectly, as principal, agent or otherwise, of any products competitive with the products, or services competitive with the services, developed or marketed by Company.

Written request for consent to be released from the Non-Competition provisions of this Agreement may be submitted by the Employee to the Company following the termination of Employee’s employment and must include all available information described in Section 5 below. The Company will respond to the request for such consent within two (2) weeks of the request, except as provided in Section 5. In the Company’s sole discretion, it may release Employee from the Non-Competition provisions of this Agreement, or reduce the non-competition period from a period of one (1) year immediately following Employee’s termination to a shorter duration (“Non-Competition Period”). In the event the Company does not release the Employee from the Non-Competition provision, for the duration of the Non-Competition Period, the Company will pay Employee an amount equal to sixty percent (60%) of Employee’s base salary as of the date of the termination of Employee’s employment (“Non-Competition Payment”), in accordance with the Company’s customary pay practices in effect at the time each payment is made. The Non-Competition Payment shall be reduced by (a) the amount of any severance Employee receives from the Company; and (b) the amount of any salary received during the Non-Competition Period from employment in any capacity with an entity that is not a Competitor Business to the extent that any such salary exceeds forty percent (40%) of Employee’s base salary as of the date of Employee’s termination from employment with the Company (annualized or pro-rated to correspond to the Non-Competition Period). By way of example, assuming that the Non-Competition Period is six (6) months and that Employee’s base salary as of the termination date is $100,000, the Non-Competition Payment would not be reduced pursuant to subsection (b) herein so long as any salary received during the Non-Competition Period by Employee from an entity that is not a Competitor Business remained under $20,000.

4. Non-Solicitation and Non-Interference. The Employee hereby covenants and agrees that at no time during the Employee’s employment with Company and for a period of one (1) year immediately following termination of Employee’s employment with the Company, whether voluntary or involuntary, shall the Employee:

(a) solicit (other than on behalf of the Company) business or contracts for any products or services of the type provided, developed or under development by the Company during the Employee’s employment by the Company, from or with any person or entity which was a customer of the Company for such products or services, or any prospective customer which the Company had solicited as of, or within one (1) year prior to, the Employee’s termination of employment with the Company; or directly or indirectly contract with any such customer or prospective customer for any product or service of the type provided, developed or which was under development by the Company during the Employee’s employment with the Company; or

(b) knowingly interfere or attempt to interfere with any transaction, agreement or business relationship in which the Company was involved during the Employee’s employment with the Company, nor will the Employee act in any way with the purpose or effect of hiring anyone who has been an employee of the Company, its divisions or subsidiaries; or soliciting, recruiting or encouraging, directly or indirectly, any of the Company’s employees to leave the employ of the Company, its divisions or its subsidiaries.

5. Notification of New Employment. Employee acknowledges and agrees that for a period of one (1) year following the date of termination of Employee’s employment with the Company, Employee will inform the Company, prior to the acceptance of any job or any work as an independent contractor, of the identity of any new employer or other entity to which Employee is providing consulting or other services, along with Employee’s starting date, title, job description, salary, and any other information which the Company may reasonably request to confirm Employee’s compliance with the terms of this Agreement. If Employee does not provide all information reasonably requested by the Company as provided in this Section, the Company’s time to respond to a request for release from the Non-Competition provision under Section 3 will be extended to six (6) weeks, or until such time as the information is provided for the Company to make an informed decision.

6. Reasonableness of Restrictions. Employee acknowledges and agrees that the restrictions imposed by this Agreement are fair and reasonably required for the protection of the Company, and will not preclude Employee from becoming gainfully employed following the termination, for any reason, of employment with the Company. The Employee acknowledges that Employee will provide unique services to the Company and that this covenant has unique, substantial, and immeasurable value to the Company. In the event that the provisions of this Agreement should ever be deemed to exceed the limitations permitted by applicable laws, Employee and the Company agree that such provisions shall be reformed to the maximum limitations permitted by the applicable laws. The Employee further acknowledges that the decision whether to consent to release Employee from the provisions of this Agreement is within the sole discretion of the Company.

7. Injunctive Relief. Employee acknowledges and agrees that in the event of a violation or threatened violation of any provision of this Agreement, the Company will sustain irreparable harm and will have the full right to seek injunctive relief, in addition to any other legal remedies available, without the requirement of posting bond.

8. Survivability. This Agreement shall remain binding in the event of the termination, for any reason, of employment with the Company.

9. Governing Law. The formation, construction and interpretation of this Agreement shall at all times and in all respects be governed by the laws of the State of Maryland.

10. Severable Provisions.
