“Without limiting the foregoing, all previously forfeited Units held by the Managing Member shall be re-issued to other Members then within the employ (or serving as directors) of Aircell, without regard to the limitation on the issuance of additional Units under Section 4.05 and without regard to the qualification of such Units as “profits interests” under Section 7.01(b).

(b) The first sentence of Section 4.05(a) of the LLC Agreement is hereby deleted and replaced in its entirety as follows:

“The Managing Member may cause the Company to issue an unlimited number of additional Units from time to time in respect of the corresponding amount of Aircell Common Stock held by the Company, except as provided in Section 4.01(c) with respect to the re-issuance of previously forfeited Units as other than profits interests upon a Change of Control.”

Section 3. Distributions.

(a) Section 7.01(a) of the LLC Agreement is hereby deleted and replaced in its entirety as follows:

“(a) Generally. Distributions shall be made when Common Stock Proceeds are received by the Company and in such amounts as determined by the Managing Member and shall be made among the Members in cash or other property in amounts determined by the procedures set forth in Sections 7.01(b) and 7.01(c).

3

Notwithstanding the foregoing, the Managing Member shall have the sole discretion with respect to when to make any such distributions in the event that the Common Stock Proceeds are as a result of, or related to, the initial public offering of Common Stock, including making such distributions after any underwriter lock-up period as described in Section 8.01(e) of this Agreement. Notwithstanding any provision to the contrary contained in this Agreement, (i) the Company shall not make a distribution to any Member on account of its Units if such distribution would violate the Act or other applicable law and (ii) the Company shall not be required to distribute any amount to the extent that the Company could be subject to any liability to refund or repay such amount or any liability arising out of the event giving rise to such amount except to Members who have agreed to assume such liability to the extent of the amount to be distributed in connection with such event.”

(b) Section 7.01(b) of the LLC Agreement is hereby deleted and replaced in its entirety as follows:

“(b) Distribution Amounts in Respect of Units. (i) Generally. Except as otherwise provided in this paragraph, any amounts of Common Stock Proceeds to be distributed to Members pursuant to Section 7.01(a) shall be allocated to the Members pro rata in accordance with their respective Unit Ownership. The amount allocated to a Member attributable to his Vested Units will be distributed to such Member. The amount allocated to a Member with respect to his Unvested Units will be held in escrow by the Managing Member and paid out to such Member as his Unvested Units vest; provided that if a Member’s Unvested Units are forfeited to the Managing Member pursuant to Section 8.02, any such amounts then held in escrow by the Managing Member shall automatically be released and paid to the Managing Member. Notwithstanding the foregoing, except as provided in Section 4.01(c) with respect to the re-issuance of previously forfeited Units as other than profits interests upon a Change of Control, all Units are intended to constitute “profits interests” within the meaning of IRS Revenue Procedures 93-27 and 2001-43, and the Managing Member shall adjust the distributions allocable to any Unit to the minimum extent necessary to ensure such treatment of each Unit. For the avoidance of doubt, no such adjustments shall be necessary or apply to the “Initial Units” described in Section 4.02, and any increase in amounts distributable to the Managing Member as a result of such adjustments being made in respect of Units shall be available, at the discretion of the Managing Member, for re-allocation to other Members then within the employ (or serving as directors) of Aircell. Each Member receiving a re-allocation pursuant to the preceding sentence acknowledges and agrees that such receipt shall be regarded as compensation for which such Member shall be responsible for the payment of all applicable payroll withholding and other taxes.”

(c) Section 7.01(c) of the LLC Agreement is hereby deleted in its entirety.

Section 4. No Other Amendment. Except as expressly set forth herein, this Amendment shall not by implication or otherwise alter, modify, amend or in any way affect any of the terms, conditions, obligations, covenants or agreements contained in the LLC Agreement, all of which are ratified and affirmed in all respects and shall continue in full force and effect.
