NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth in this Agreement, and intending to be legally bound hereby, the Parties agree as follows:

ARTICLE I

THE ACQUISITION

SECTION 1.1 The Acquisition. On the terms and subject to the conditions contained in this Agreement, at the Closing, Mesa shall sell, assign, transfer and convey to Armada, and Armada shall purchase, acquire and accept from Mesa, all of the issued and outstanding stock of Mesa Sub owned by Mesa (collectively, the “Purchased Assets”) for the Acquisition Consideration, as defined below.

SECTION 1.2 The Acquisition Consideration.

(a) The consideration for the Purchased Assets will consist of the following (collectively, the “Acquisition Consideration”):

(i) 0.40 shares (subject to rounding as provided in Section 1.2(b)) of validly issued, fully paid and non-assessable shares of Armada Common Stock (the “Stock Consideration”) for each share of the common stock, par value $0.0001 per share, of Mesa (the “Mesa Common Stock”) issued and outstanding as of the Closing Date (the “Consideration Ratio”), which Mesa shall distribute pro rata to each holder of shares of Mesa Common Stock as of the close of business on the Business Day immediately prior to the Closing Date, in accordance with Section 2.1;

(ii) Armada shall issue, in satisfaction of Mesa’s obligations under the Mesa Stock Options, Mesa Restricted Stock Grants and Mesa Warrants, all as defined and described below, substantially comparable options, restricted shares and warrants (the “Derivative Consideration), with such share and price adjustments as more fully described below in Section 2.2 hereof; and

(iii) Armada shall assume and agree to pay, perform and discharge all of Mesa’s liabilities arising on or before the Closing Date, as defined below, or as specifically permitted under the terms of this Agreement.

(b) Notwithstanding any other provision in this Agreement, no fractional shares of Armada Common Stock and no certificates or other evidence of ownership thereof will be issued in connection with the Acquisition or the Reorganization, and no holder of Mesa Common Stock shall be entitled to any voting rights, rights to receive any dividends or distributions or other rights as a stockholder of Armada with respect to any fractional share of Armada Common Stock that would have otherwise been deliverable to such holder of Mesa Common Stock in connection with the Reorganization. To the extent that any shareholder of Mesa would otherwise be entitled to receive a fractional share of Armada Common Stock in connection with the Reorganization, in lieu of any fractional shares of Armada Common Stock that would have otherwise been issued, the Stock Consideration will be increased by a number of shares of Armada Common Stock equal to the number of Mesa shareholders entitled to receive an additional share of Armada Common Stock based upon the rounding up or down to the nearest whole number (with a fractional interest equal to 0.5 rounded upward to the nearest whole number); provided, that each such holder of Mesa Common Stock shall receive at least one share of Armada Common Stock.

Page 2 of 73

(c) Notwithstanding any other provision in this Agreement, any liability of Mesa not constituting the Assumed Liabilities will be a retained liability of Mesa, and shall remain the sole responsibility of Mesa and shall be retained, paid, performed and discharged by Mesa.

SECTION 1.3 The Dissolution. On the terms and subject to the conditions set forth in this Agreement, and in accordance with the DGCL and the Mesa Stockholder Consent, as defined herein, within two (2) Business Days after the Closing Date, Mesa shall file a certificate of dissolution (the “Mesa Certificate of Dissolution”) with the Secretary of State of Delaware to dissolve Mesa (the “Dissolution”) and to effect the distribution of the Stock Consideration and the Derivative Consideration in accordance with Sections 2.1 and 2.2 in furtherance of the Reorganization.

SECTION 1.4 Closing. On the terms and subject to the conditions set forth in this Agreement, the closing of the Acquisition and the transactions contemplated by this Agreement (the “Closing”) will take place as soon as possible, but in any event no later than the fifth (5^th) Business Day after the satisfaction or waiver (subject to Applicable Law) of the conditions set forth in Article VII (other than those conditions which by their nature are intended to be satisfied at the Closing, but subject to the satisfaction or waiver (subject to Applicable Law) of those conditions at the Closing) unless another time or date is agreed to in writing by the Parties (the actual time and date of the Closing being referred to herein as the “Closing Date”). The Closing shall be held at the offices of Xxxxxxxx & Company, LLP, 000 Xxxx Xxxxxx, Xxxxx 000, Xxx Xxxx, Xxx Xxxx 00000, unless another place is agreed to in writing by the Parties.

SECTION 1.5 Further Assurances. At and after the Closing Date, the officers of Mesa shall be authorized to execute and deliver, in the name and on behalf of Mesa, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of Mesa or Mesa Sub, any other actions and things to vest, perfect or confirm of record or otherwise in Armada any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by Armada as a result of, or in connection with, the Acquisition.

SECTION 1.6 Certain Adjustments. If, between the date of this Agreement and the Closing Date, the outstanding Mesa Common Stock shall have been changed into a different number of shares or different class by reason of any reclassification, recapitalization, stock split, split-up, combination, readjustment or exchange of shares or a stock dividend or dividend payable in any other securities shall be declared with a record date within such period, or any similar event shall have occurred, the Stock Consideration shall be appropriately adjusted to provide to the holders of Mesa Common Stock, Mesa Warrants, Mesa Stock Options and Mesa Restricted Stock Grants the same economic effect as contemplated by this Agreement prior to such event; provided, that nothing in this Section 1.6 shall be construed to permit Mesa to take any action with respect to its securities that is prohibited by this Agreement.

SECTION 1.7 Right to Revise Structure. At Armada’s election, the Acquisition may alternatively be structured so that Mesa or Mesa Sub is merged with and into Armada or a Subsidiary of Armada; provided, that no such change shall (a) alter or change the amount or kind of the Stock Consideration or alter or change adversely the treatment of the holders of Mesa Stock Options, Mesa Restricted Stock Grants or Mesa Warrants, or (b) conflict with Section 6.10. In the event Armada makes such an election, Mesa and Mesa Sub shall cooperate with Armada and shall execute an appropriate amendment to this Agreement to effect such election.

ARTICLE II

DISTRIBUTION OF CERTIFICATES

SECTION 2.1 Distribution Procedures. Each holder of record of shares of Mesa Common Stock as of the close of business on the Business Day immediately prior to the Closing Date shall be entitled to receive as a distribution from Mesa 0.40 shares (subject to rounding as provided in Section 1.2(b)) of the Stock Consideration for each share of Mesa Common Stock held by such person as of such time. As promptly as practicable, but in any event within ten (10) Business Days after the Closing Date, Mesa shall, or shall cause such bank or trust company Mesa appoints (which shall be reasonably acceptable to Armada) for the purpose of distributing certificates of Armada Common Stock representing the Stock Consideration (the “Liquidation Agent”) to, send to each holder of record of shares of Mesa Common Stock as of the close of business on the Business Day immediately prior to the Closing Date certificates of Armada Common Stock representing the Stock Consideration to which each holder is entitled. Notwithstanding the foregoing, the shares of Armada Common Stock constituting Stock Consideration to be distributed, at Armada’s option, may be in uncertificated book-entry form, unless a physical certificate is requested by a holder of shares of Mesa Common Stock or is otherwise required under Applicable Law. If shares of Armada Common Stock are distributed in uncertificated book-entry form, Mesa or Liquidation Agent shall, or shall cause the transfer agent for Armada’s Common Stock to, transmit to each holder of Mesa Common Stock who is entitled to receive the Stock Consideration a confirmation that the Armada Common Stock to be issued to such holder has been registered in such person’s name on Armada’s stock ledger. No interest will be paid or will accrue on the Stock Consideration. In the event of a transfer of ownership of shares of Mesa Common Stock which is not registered in the transfer records of Mesa (such shares, the “Unregistered Transferred Shares”), the aggregate Stock Consideration that the holder of record of such Unregistered Transferred Shares has the right to receive with respect thereto pursuant to this Section 2.1 may be issued and paid to the transferee of such Unregistered Transferred Shares if (A) a certificate representing such Unregistered Transferred Shares is presented to Mesa or Liquidation Agent accompanied by all documents required to evidence and effect such transfer and (B) the Person requesting such payment of Stock Consideration shall (1) pay to Mesa or Liquidation Agent any applicable stock transfer taxes required as a result of such payment to a Person other than the registered holder of such Unregistered Transferred Shares or (2) establish to the reasonable satisfaction of Mesa or Liquidation Agent that such stock transfer taxes have been paid or are not applicable.

SECTION 2.2 Mesa Stock Options; Restricted Stock Grants; Warrants.

(a) Mesa Stock Options. Subject to the terms hereof and, to the extent required by the terms of the Mesa Stock Options, the consent thereto of the holders of the Mesa Stock Options, Armada shall assume all outstanding Mesa Stock Options, vested and unvested, disclosed in Schedule 2.2(a) of the Mesa Disclosure Letter in connection with the transactions contemplated hereby. Not later than ten (10) days prior to the scheduled or anticipated Closing Date, Mesa shall send a notice to all holders of Mesa Stock Options, which notice shall notify such holders that Armada will be assuming all Mesa Stock Options following the Closing Date, or substituting new options therefor, pursuant to Armada’s Option Plan (a “Converted Option”). All holders of Mesa Stock Options shall be, subject to Section 2.6, entitled to receive a number of stock options pursuant to Armada’s Option Plan allowing the holder to purchase a number of shares of Armada Common Stock equal to the product of (i) 0.40 multiplied by (ii) the number of Mesa Stock Options currently held by such holder immediately prior to the Closing Date (with any fraction resulting from such multiplication to be rounded to the nearest whole number, and with 0.5 shares rounded upward to the nearest whole number) with the exercise price per share of the new option equal to the quotient of (y) the exercise price of the Mesa Stock Option divided by (z) 0.40 (rounded to the nearest whole cent, and with $0.005 rounded upward to the nearest whole cent). Such new stock option, to the extent permitted by applicable law and Armada’s Option Plan, shall have the same vesting schedule and other terms and conditions as such holder’s Mesa Stock Option.

Page 4 of 73

(b) Mesa Restricted Stock Grants. Subject to the terms hereof and, to the extent required by the terms of the Mesa Restricted Stock Grants, the consent thereto of the holders of Mesa Restricted Stock Grants, Armada shall assume all outstanding Mesa Restricted Stock Grants disclosed in Schedule 2.2(b) of the Mesa Disclosure Letter in connection with the transactions contemplated hereby. Not later than ten (10) days prior to the scheduled or anticipated Closing Date, Mesa shall send a notice to all holders of Mesa Restricted Stock Grants, which notice shall notify such holders that Armada will be assuming all Mesa Restricted Stock Grants following the Closing Date, or substituting new restricted share agreements therefor, pursuant to Armada’s Option Plan (a “Converted Restricted Stock Grant”). All holders of Mesa Restricted Stock Grants shall be, subject to Section 2.6, entitled to receive a number of restricted stock awards to purchase a number of shares of Armada Common Stock equal to the product of (i) 0.40 multiplied by (ii) the number of Mesa Restricted Stock Grants held by such holder immediately prior to the Closing Date (with any fraction resulting from such multiplication to be rounded to the nearest whole number, and with 0.5 shares rounded upward to the nearest whole number). Such new restricted grant, to the extent permitted by applicable law and Armada’s Option Plan, shall have the same vesting schedule and other terms and conditions as such holder’s Mesa Restricted Stock Grants.

(c) Mesa Warrants. Subject to the terms hereof and, to the extent required by the terms of the Mesa Warrants, the consent thereto of the holders of Mesa Warrants, Armada shall assume all outstanding Mesa Warrants. At Closing, each Mesa Warrant which is outstanding immediately prior to the Closing Date shall, in accordance with its terms, cease to represent a right to acquire shares of Mesa Common Stock and shall be converted, at the Closing Date, into a right to acquire shares of Armada Common Stock (a “Converted Warrant”), on the same contractual terms and conditions as were in effect immediately prior to the Closing Date under the terms of the Mesa Warrant or other related agreement or award pursuant to which such Mesa Warrant was granted; provided, that (i) the number of shares of Armada Common Stock subject to each such Converted Warrant shall be equal to the product of (A) 0.40 multiplied by (B) the number of shares of Mesa Common Stock subject to each such Mesa Warrant immediately prior to the Closing Date (with any fraction resulting from such multiplication to be rounded to the nearest whole number, and with 0.5 shares rounded upward to the nearest whole number, unless such Mesa Warrant provides for different treatment of fractions of a share in such circumstances), with any fractional shares rounded down to the next lower whole number of shares, and (ii) such Converted Warrant shall have an exercise price per share of Armada Common Stock equal to the quotient of (A) the exercise price per share of Mesa Common Stock subject to such Converted Warrant immediately prior to the Closing Date divided by (B) 0.40 (rounded to the nearest whole cent, and with $0.005 rounded upward to the nearest whole cent, unless such Mesa Warrant provides for different treatment of fractions of a cent in such circumstances), with any fractional cents rounded up to the next higher number of whole cents. Not later than ten (10) days prior to the scheduled or anticipated Closing Date (or within any other timeframe required by the terms of a Mesa Warrant), Mesa shall send a notice to all holders of Mesa Warrants of the foregoing.

(d) Prior to Closing, Mesa shall take any actions necessary to effect the transactions anticipated by Section 2.2(a) and (b) under the Mesa Stock Plans and any option agreement thereunder and any other plan or arrangement of Mesa (whether written or oral, formal or informal). Prior to the Closing Date, Armada shall take any actions necessary to effect the transactions anticipated by Section 2.2(a) and (b) under the Armada Stock Plans. As soon as practicable following the date hereof, Mesa shall deliver or cause to be delivered to each holder of a Mesa Stock Option and/or Mesa Restricted Stock Grant and/or Mesa Warrants any certifications, notices or other communications required by the terms of such Mesa Stock Option and/or Mesa Restricted Stock Grant and/or Mesa Warrant or any agreement entered into with respect thereto to be delivered to such holder prior to the consummation of the Acquisition and the other transactions contemplated by this Agreement.

Page 5 of 73

(e) Armada shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Armada Common Stock for delivery upon exercise of all Converted Options, Converted Restricted Stock Grants and Converted Warrants.

(f) Mesa shall take all steps to ensure that, at the Closing Date, neither it nor any of its Subsidiaries is or will be bound by any Mesa Stock Options, other options, warrants, rights, agreements or awards which would entitle any Person, other than Armada or its Subsidiaries, to own any capital stock of Mesa or any of its Subsidiaries or to Armada any payment, right or interest in respect thereof. As soon as practicable after the Closing Date, Armada shall take appropriate actions to collect Mesa Options and Mesa Restricted Stock Grants and the agreements evidencing the same, which shall be deemed to be canceled and shall entitle the holder to exchange the Mesa Options and Mesa Restricted Stock Grants for Converted Options and Converted Restricted Stock Grants as provided above.

SECTION 2.3 No Further Ownership Rights in Mesa Common Stock. All Stock Consideration paid upon distribution of shares of Armada Common Stock in accordance with the terms of Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Mesa Common Stock. Upon completion of the Dissolution, all shares of Mesa Common Stock shall be void and no holder of shares of Mesa Common Stock shall have any further rights or obligations with regard to Mesa.

SECTION 2.4 No Liability. None of Armada, Mesa, Mesa Sub or the Liquidation Agent shall be liable to any Person in respect of any Stock Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law, or delivered pursuant to the judgment, order or decree of any court or tribunal.

SECTION 2.5 Withholding Rights. Each of the Liquidation Agent, Armada and Mesa Sub shall be entitled to withhold from any consideration payable or otherwise deliverable pursuant to this Agreement any portion thereof as is reasonably necessary to ensure all withholding obligations under Applicable Law are met. To the extent that such consideration is so withheld, it shall be treated for all purposes under this Agreement as having been paid or delivered to the Person to whom such consideration would otherwise have been paid or delivered.

SECTION 2.6 Stock Transfer Books. The stock transfer books of Mesa shall be closed immediately upon the Closing and there shall be no further registration of transfers of shares of Mesa Common Stock thereafter on the records of Mesa.

ARTICLE III

SECTION 3.1 Organization, Standing and Power; Subsidiaries.

(a) Except as disclosed in Schedule 3.1(a) of the Mesa Disclosure Letter, Mesa and each of its Subsidiaries is a corporation or other Person duly organized, validly existing and in good standing under the laws of its respective jurisdiction of incorporation or organization, has the requisite power and authority to own, lease and operate its assets and properties and to carry on its business as now being conducted. Mesa and each of its Subsidiaries is duly qualified and in good standing to do business in each jurisdiction in which the nature of its business or the ownership or leasing of its properties makes such qualification necessary, other than in such jurisdictions where the failure so to qualify or to be in good standing has not had and would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect on Mesa. The copies of the certificate of incorporation and bylaws of Mesa and of its Subsidiaries that were previously furnished or made available to Armada are true, complete and correct copies of such documents as in effect on the date of this Agreement and have not been amended since the date hereof, and neither Mesa nor any of its Subsidiaries is in violation of any of their respective organizational documents.

Schedule 3.1(b) of the Mesa Disclosure Letter lists all of the Subsidiaries of Mesa and, for each such Subsidiary, the jurisdiction of its incorporation or organization and its directors and officers as of the date of this Agreement. Neither Mesa nor any of its Subsidiaries directly or indirectly owns any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for, any corporation, partnership, joint venture or other business association or entity.

(c) Each Mesa Plan is in compliance with ERISA, the Code, all other Applicable Laws and its governing documents, except as would not reasonably be expected to result, individually or in the aggregate, in a material liability of Mesa and its Subsidiaries. Each Mesa Plan that is intended to be a qualified plan under Section 401(a) of the Code has received a favorable determination letter or an opinion letter from the IRS covering all Tax law changes, and Mesa is not aware of any circumstances that could reasonably be expected to result in the loss of the qualification of such Mesa Plan under Section 401(a) of the Code.

No liability, claim, action, litigation, audit, examination, investigation or administrative proceeding has been made, commenced or, to the Knowledge of Mesa, threatened with respect to any Mesa Plan (other than routine claims for benefits payable in the ordinary course). No disallowance of a deduction under Section 162(m) of the Code for any amount paid or payable by Mesa or any Subsidiary thereof has occurred or is reasonably expected to occur. All Mesa Plans that are subject to Section 409A of the Code are in compliance with the requirements of Code Section 409A and the regulations thereunder. Neither the execution of this Agreement, stockholder approval of this Agreement nor the consummation of the transactions contemplated hereby (either alone or upon the occurrence of any additional or subsequent event) will: (i) entitle any employees of Mesa or any of its Subsidiaries to severance pay or any increase in severance pay upon any termination of employment after the date hereof, (ii) accelerate the time of payment or vesting, result in any payment or funding (through a grantor trust or otherwise) of compensation or benefits under, increase the amount payable or result in any other material obligation pursuant to, or result in “parachute payment” (as such term is defined in Section 280G of the Code) under any of Mesa Plans, or (iii) limit or restrict the right of Mesa to merge, amend or terminate any of Mesa Plans. No current or former officer, director or employee of Mesa or any Subsidiary of Mesa has or will obtain a right to receive a gross-up payment from Mesa or any such Subsidiary with respect to any excise taxes that may be imposed upon such individual pursuant to Section 409A of the Code, Section 4999 of the Code or otherwise. Except as required to maintain the tax-qualified status of any Mesa Plan intended to qualify under Section 401(a) of the Code, no condition or circumstance exists that would prevent the amendment or termination of any Mesa Plan.
