STATEMENT OF AGREEMENT

NOW, THEREFORE, for good and valuable consideration, the sufficiency and receipt of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows:

ARTICLE 1

THE MERGER

In connection with the Merger, the respective boards of directors of Radyne, Merger Sub and AeroAstro have, by resolutions duly adopted, approved the following provisions of this Article 1 as the agreement and plan of merger required by the applicable provisions of the Delaware General Corporation Law (“Delaware Law”):

1.1 The Merger. At the Effective Time (as defined in Section 1.3), in accordance with this Agreement and Delaware Law, Merger Sub shall be merged with and into AeroAstro, the separate existence of Merger Sub (except as such existence may be continued by operation of law) shall cease, and AeroAstro shall continue as the surviving corporation under the corporate name it possesses immediately prior to the Effective Time. AeroAstro, in its capacity as the corporation surviving the Merger, sometimes is referred to herein as the “Surviving Corporation.”

1.2 Effect of the Merger. The Surviving Corporation shall possess all the rights, privileges, immunities and franchises, of a public as well as of a private nature, of each of Merger Sub and AeroAstro (together, the “Constituent Corporations”); all property, real, personal and mixed, and all accounts payable arising in the ordinary course of business and accrued expenses due on whatever account, and all debts, liabilities and duties due to each of the Constituent Corporations shall be transferred to and vested in the Surviving Corporation without further act or deed; and the Surviving Corporation shall be responsible and liable for all liabilities and obligations of each of the Constituent Corporations, in each case in accordance with Delaware Law, but subject, as between the parties, to the provisions below.

1.3 Consummation of the Merger. As soon as is practicable after the satisfaction or waiver of the conditions set forth in Article 7, and in no event later than five business days after such satisfaction or waiver, the parties hereto will file, or cause to be filed, a certificate of merger (the “Certificate of Merger”) in such form as is required by and executed in accordance with the relevant provisions of Delaware Law and make, or cause to be made, all other filings or recordings required under the Delaware Law. The Merger shall be effective at such time as the Certificate of Merger is duly filed with the Delaware Secretary of State or at such subsequent time as the parties shall agree and be specified in the Certificate of Merger. The date and time when the Merger shall become effective is referred to as the “Effective Time.”

1.4 Articles of Incorporation and Bylaws; Directors and Officers. The Articles of Incorporation of the Surviving Corporation, as in effect immediately prior to the Effective Time, shall be amended and restated to read the same as the Certificate of Incorporation of Merger Sub as in effect immediately prior to the Effective Time, except that Section 1 of the amended and restated Articles of Incorporation of the Surviving Corporation, instead of reading the same as Section 1 of the Certificate of Incorporation of Merger Sub, shall read as follows: “The name of this corporation is AeroAstro, Inc.” The Bylaws of AeroAstro as the Surviving Corporation shall be amended and restated to read the same as the Bylaws of Merger Sub as in effect immediately prior to the Effective Time, except that all references to Merger Sub in the Bylaws of the Surviving Corporation shall be changed to refer to AeroAstro, Inc. The directors of Merger Sub

holding office immediately prior to the Effective Time shall be the directors of the Surviving Corporation immediately after the Effective Time, together with Xx. Xxxx Xxxxxxx. The officers of AeroAstro holding office immediately prior to the Effective Time shall be the officers (holding the same offices as they held with AeroAstro) of the Surviving Corporation immediately after the Effective Time, except that Xxxxx Xxxxxx shall become the Chairman of the Board of the Surviving Corporation and Xxxxxxx X. Xxxxxx shall become the Chief Financial Officer and Secretary of the Surviving Corporation.

1.5 Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of Merger Sub, AeroAstro or the holders of any of the following securities:

(a) Each share of common stock, par value $0.001 per share, of AeroAstro (the “AeroAstro Common Stock”) issued and outstanding immediately prior to the Effective Time shall automatically be cancelled and extinguished and converted into and become a right to receive an amount equal to the Per Share Merger Consideration. The “Per Share Merger Consideration” means the amount determined by dividing (A) the sum of the Adjusted Cash Consideration, the aggregate exercise price payable upon exercise of all Cash-Out Options (as defined below) and $750,000 by (B) the number of Fully Diluted Shares. The “Adjusted Cash Consideration” means the Cash Consideration less the reduction set forth in Section 1.6. The “Cash Consideration” means $17,250,000 in cash. The “Fully Diluted Shares” means the sum of (A) the aggregate number of shares of AeroAstro Common Stock issued and outstanding immediately prior to the Effective Time and (B) the number of shares of AeroAstro Common Stock issuable upon the exercise of Cash-Out Options. The “Merger Consideration,” in the aggregate, means (i) the Adjusted Cash Consideration, plus (ii) the number of shares of Radyne Common Stock equal to (A) $750,000 divided by (B) the Share Closing Price (the “Merger Shares”). The “Share Closing Price” shall be equal to $9.18¹. Notwithstanding anything to the contrary in this Section 1.5(a), Xx. Xxxx Xxxxxxx shall be allocated all of the Merger Shares with the remainder of the Merger Consideration due to him in the form of Cash Consideration, and all other AeroAstro Shareholders will be allocated the remaining Cash Consideration on a pro rata basis based upon the Fully Diluted Shares excluding any shares beneficially held by Xx. Xxxx Xxxxxxx, net of any stockholder loans owed to AeroAstro.

(b) The Merger Shares shall be adjusted to reflect fully the effect of any stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Radyne Common Stock), reorganization, recapitalization or other like change with respect to Radyne Common Stock occurring after the date hereof and prior to the Effective Time.

(c) No fraction of a share of Radyne Common Stock will be issued, but in lieu thereof each holder of shares of AeroAstro Common Stock who would otherwise be entitled to a fraction of a share of Radyne Common Stock (after aggregating all fractional shares of Radyne Common Stock to be received by such holder) shall receive from Radyne an amount of cash (rounded to the nearest whole cent) equal to the product of (i) such fraction, multiplied by (ii) the Share Closing Price.

¹	The average reported closing price for Radyne Common Stock on the NASDAQ Stock Market as reflected in the Western Edition of the Wall Street Journal starting 20 trading days prior to and ending on June 14, 2007.

(d) Each share of AeroAstro Common Stock issued and outstanding immediately prior to the Effective Time and held in the treasury of AeroAstro shall automatically be canceled and extinguished, and no payment shall be made with respect thereto.

(e) Each share of common stock, par value $.001 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall automatically be converted into and become one validly issued, fully paid and nonassessable share of common stock, par value $.001 per share, of the Surviving Corporation.

1.6 Adjustment to the Merger Consideration. At the Closing, Radyne shall pay on behalf of AeroAstro and the AeroAstro Shareholders the then unpaid fees, if any, as designated in writing by AeroAstro to Radyne of (a) Xxxx, Xxxxxx & XxXxxxxxx, L.L.P., and (b) Squire, Xxxxxxx & Xxxxxxx L.L.P. (collectively, the “Transaction Fees”). Any amounts that are paid by Radyne pursuant to this Section 1.6 shall reduce the Cash Consideration.

1.7 Company Stock Options.

(a) Schedule 3.3 sets forth each outstanding, but unexercised option to acquire shares of AeroAstro Common Stock (collectively, the “AeroAstro Options”). Each holder of an AeroAstro Option shall be referred to as an “Optionholder.” Prior to the Effective Time, AeroAstro shall use its reasonable best efforts to enter into an agreement, in a form reasonably acceptable to Radyne (each, an “Optionholder Agreement”), with each Optionholder of an outstanding AeroAstro Option containing the terms described below.

(b) Each AeroAstro Option outstanding as of the Effective Time will be either (i) cancelled in exchange for the payment of the Option Consideration (as defined below) or for a cash payment pursuant to Section 1.7(h) below or (ii) replaced by an option to purchase shares of Radyne Common Stock pursuant to Section 1.7(d) (“Replacement Option”), as provided herein. Each vested AeroAstro Option that is to be cancelled shall be referred to as a “Cash-Out Option,” and each AeroAstro Option that is to be replaced by an option to purchase shares of Radyne Common Stock shall be referred to as a “Rollover Option”. Each holder of a vested AeroAstro Option outstanding as of the Effective Time may, by executing an Optionholder Agreement, elect to have such vested AeroAstro Option treated either as a Cash-Out Option or a Rollover Option. To the extent that such holder does not execute an Optionholder Agreement making such election, his or her vested AeroAstro Option will be treated as a Cash-Out Option. Except as otherwise provided in Section 1.7(h) below, each unvested AeroAstro Option outstanding as of the Effective Time shall be treated as a Rollover Option (whether or not the holder of such option delivers an Optionholder Agreement).

(c) At the Effective Time, each outstanding Cash-Out Option shall be cancelled, and in consideration for such cancellation, Radyne shall pay the Option Consideration to the Optionholder in full satisfaction of such Cash-Out Option. “Option Consideration” means, with respect to each Cash-Out Option, an amount in cash equal to the product of (i) the excess of the Per Share Merger Consideration over the exercise price per share of such Cash-Out Option

and (ii) the number of shares for which such Cash-Out Option is then exercisable. Each Optionholder Agreement relating to a Cash-Out Option will incorporate appropriate terms of this Agreement, including but not limited to (i) the withholding of the Per Share Escrow Amount under Section 1.8; (ii) the withholding of the Expense Fund and (iii) the appointment of the Shareholders’ Representative in Section 1.12.

(d) At the Effective Time, each Rollover Option will be replaced by a Replacement Option to acquire, on the same terms and conditions as were applicable under the applicable stock option agreement and AeroAstro stock option plan pursuant to which such Rollover Option was granted, that number of shares of Radyne Common Stock determined by multiplying the number of shares of AeroAstro Common Stock subject to such Rollover Option by 0.16², rounded, if necessary, to the nearest whole share of Radyne Common Stock, at a price per share (rounded to the nearest one-hundredth of a cent) equal to the per share exercise price specified in such Rollover Option divided by 0.16; provided, however, that in the case of any Rollover Option that does not qualify as an incentive stock option under Section 422 of the Code, the option price, the number of shares subject to such option, and the terms and conditions of exercise of the related Replacement Option shall be determined in a manner consistent with the requirements of Section 409A of the Code.

(e) As soon as practicable after the Effective Time, with respect to holders of AeroAstro Options that do not execute and deliver an Optionholder Agreement, Radyne shall deliver appropriate notices setting forth such holders’ rights under this Section 1.7 and, as to Replacement Options, agreements that such holders must execute as a condition of the grant of the Replacement Options.

(f) Radyne shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Radyne Common Stock for delivery upon exercise of the Replacement Options in accordance with this Section 1.7.

(g) Each of Radyne, the Surviving Corporation, the Shareholders’ Representative and the Transfer Agent shall be entitled to deduct and withhold from any Option Consideration otherwise payable to any Optionholder pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of applicable Tax law. To the extent that such amounts are so withheld or paid over to or deposited with the relevant governmental authority by Radyne, the Surviving Corporation or the Transfer Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the applicable person in respect to which such deduction and withholding was made.

(h) Notwithstanding anything to the contrary in this Section 1.7, to the extent Radyne determines in good faith that the grant of any Replacement Option to replace a Rollover Option could violate any federal or state securities laws, upon written notice to AeroAstro

The ratio of (i) the Merger Consideration divided by the number of shares of AeroAstro common stock on a fully diluted basis to (ii) Radyne’s current stock price—computed as the average reported closing price for Radyne Common Stock on the NASDAQ Stock Market as reflected in the Western Edition of the Wall Street Journal starting 20 trading days prior to and ending on June 14, 2007.

thereof, at the Effective Time, such Rollover Option shall be cancelled, and Radyne shall pay to the holder of such Rollover Option in full satisfaction of such Rollover Option cash equal to the product of the (i) the excess of the Per Share Merger Consideration over the exercise price per share of such option and (ii) the number of shares for which such option is then exercisable. Any such cash payment by Radyne shall be in addition to the Merger Consideration otherwise payable by Radyne pursuant to this Agreement.

1.8 Escrow.

(a) At Closing, Radyne, the Principal Shareholders, the Shareholders’ Representative and Alliance Bank of Arizona (the “Escrow Agent”) shall enter into an escrow agreement in substantially the form attached hereto as Exhibit A (the “Escrow Agreement”). The escrow agent will hold $2,000,000 (the “Escrow Amount”) in escrow (the “Escrow Fund”) as security to cover potential losses or other claims for which Radyne is entitled to indemnification or recovery pursuant to Article 8. Subject to any claims made by Radyne, the Escrow Amount will be released to the AeroAstro Shareholders within ten (10) days after the second anniversary of the Closing.

(b) The parties hereto hereby acknowledge and agree that the Escrow Amount is intended to be treated as an installment obligation for purposes of Section 453 of the Code and, unless required by applicable law, no party shall take any action or filing position inconsistent with such characterization. The parties hereto further agree that, subject to any future Treasury Regulations or other changes in the law, pursuant to Proposed Treasury Regulation Section 1.468B-8, for tax reporting purposes, all items of income, deduction and credit relating to the Escrow Amount or any portion thereof in any tax year shall be reported as allocated to Radyne with respect to all periods on or prior to the date that the distribution of the Escrow Amount (or portion thereof) is determined, and with respect to all periods thereafter to Radyne and the AeroAstro Shareholders in accordance with their respective interests in the distribution in accordance with Proposed Treasury Regulation Section 1.468B-8. The Escrow Agreement shall provide for quarterly distributions from the Escrow Fund to Radyne of amounts sufficient to pay any taxes due on any income earned on the Escrow Fund. Any income earned on the Escrow Fund, to the extent that such income exceeds the quarterly tax distributions, shall be added to and become part of the Escrow Fund. Any portion of the Escrow Amount paid to the AeroAstro Shareholders shall be included as a payment of the purchase consideration for tax purposes (to the extent not treated as imputed interest).

(c) In this Agreement, the term “Per Share Escrow Amount” shall be the Escrow Amount divided by the Fully Diluted Shares.

(d) For purposes of this Section 1.8 and the Escrow Agreement, the term AeroAstro Shareholder shall include each holder of a Cash-Out Option.

1.9 Closing. The closing (the “Closing”) of the transactions contemplated by this Agreement shall occur as soon as each of the conditions to Closing contained in Article 7 are fulfilled or waived at the offices of Xxxxx & Xxxxxx L.L.P., Xxx Xxxxxxx Xxxxxx, Xxxxxxx, Xxxxxxx 00000, or at such other place or at such other time as the parties may mutually agree upon.

Xxxx Xxxxxxx;

(b) deliver to its transfer agent (the “Transfer Agent”) an amount equal to the aggregate Per Share Merger Consideration that all AeroAstro Shareholders are entitled to pursuant to Section 1.5(a) (less (i) the aggregate Per Share Escrow Amount and the Per Share Expense Fund Amount applicable to all shares of AeroAstro Common Stock issued and outstanding immediately prior to the Effective Time and (ii) $750,000), with instructions approved in writing by the Shareholders’ Representative to pay to each AeroAstro Shareholder an amount equal to the Per Share Merger Consideration that such AeroAstro Shareholder is entitled to pursuant to Section 1.5(a) less the sum of the Per Share Escrow Amount and the Per Share Expense Fund Amount, subject to and upon receipt by the Transfer Agent of (i) the certificate or certificates representing shares of AeroAstro Common Stock held by such AeroAstro Shareholder or an affidavit reasonably acceptable to Radyne from such AeroAstro Shareholder and (ii) a letter of transmittal in form satisfactory to the Shareholders’ Representative (a “Letter of Transmittal”) executed and delivered by such AeroAstro Shareholder;

(c) deliver to AeroAstro an amount equal to the aggregate Option Consideration that the holders of Cash-Out Options are entitled to pursuant to Section 1.7(a) less the sum of the aggregate Per Share Escrow Amount and the Per Share Expense Fund Amount applicable to all Cash-Out Options, which AeroAstro shall pay (net of all amounts required to be withheld from such payment under the Code or any provision of applicable Tax Law) within three (3) business days after the Closing to the holders of Cash-Out Options (which withholdings shall be paid to the appropriate government authorities;

If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full possession of all the rights, privileges, immunities and franchises of the Constituent Corporations, or fully subject the Surviving Corporation to all debts and obligations of the Constituent Corporations, the officers and directors of the Surviving Corporation are fully authorized in the name of the Constituent Corporations or otherwise to take, and shall take, all such actions.

Once the Shareholders’ Representative determines, in his sole discretion, that the Shareholders’ Representative will not incur any additional expenses in his capacity as the Shareholders’ Representative, the Shareholders’ Representative shall distribute the remaining unused Expense Fund, if any, pro rata to the

AeroAstro Shareholders (less any amounts required to be withheld under foreign, federal, state or local laws).

No Principal Shareholder is subject to, or obligated under, any agreement, arrangement or understanding, or any law, regulation, order, judgment or decree, that would be breached or violated, or in respect of which a right of termination or acceleration would arise or any encumbrance on any of his or her assets would be created, by his or her execution, delivery and performance of this Agreement and the consummation by him or her of the transactions contemplated hereby.

He is not a party to any contract, undertaking, agreement or arrangement with any person or entity to sell, transfer or grant participations in the Merger Shares.

(d) Restricted Securities. He understands that the Merger Shares he is acquiring are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from Radyne in a transaction not involving a public offering, and that under such laws and applicable regulations such securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, he represents that he is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

prior to the date of execution of this Agreement, Radyne must make, or cause to be made, all reasonable claims for insurance under such insurance policy that may be applicable to the matter giving rise to such claim, to the same extent that it would if such Loss were not subject to indemnification hereunder, before proceeding to collection of any such claim for indemnification against the Escrow Fund or any AeroAstro Shareholder. The amount of the Loss subject to indemnification under Section 8.2(a) shall be calculated net of any amounts recovered by Radyne or its affiliates under any insurance policy as provided in this Section 8.2(d) (net of all direct unreimbursed collection expenses).

(e) For purposes of assessing indemnification for any breach of any representation or warranty made by AeroAstro or the Principal Shareholders in this Agreement, any materiality (including any “Material Adverse Change”) or knowledge qualifiers shall be eliminated, except knowledge qualifiers with respect to “investigations” or “threatened” matters.

(f) Subject to Section 8.2(g), the AeroAstro Shareholders will not be obligated to indemnify the Radyne Indemnitees for any Loss arising from Section 8.2(a)(i) except to the extent that the aggregated amount of all Losses arising from Section 8.2(a)(i) exceeds $100,000 (the “Indemnity Basket”).

(g) The Indemnity Basket will not apply under this Section 8.2 in the event any Loss is based on (i) any breach by AeroAstro or a Principal Shareholder of any of their respective representations and warranties under Section 3.2, Section 3.3, or Section 4.1; or (ii) any fraud or intentional misrepresentation or omission by AeroAstro or any of the AeroAstro Shareholders in connection with the transaction contemplated by this Agreement.

(h) Notwithstanding anything to the contrary contained herein, the maximum aggregate liability of each AeroAstro Shareholder who is not a Principal Shareholder to the Radyne Indemnitees will not exceed such AeroAstro Shareholder’s portion of the Escrow Amount.

(i) After the Escrow Amount has been fully exhausted, the maximum aggregate liability of the Principal Shareholders (other than with respect to any Loss based on (i) any breach by a Principal Shareholder of his or her representations and warranties under Section 4.1 or (ii) any intentional misrepresentation or omission by AeroAstro or the Principal Shareholders under Article 3) to the Radyne Indemnitees, in excess of the Principal Shareholders’ portion of the Escrow Amount, will not exceed $1,000,000.

(j) Notwithstanding anything to the contrary contained herein, as of a given date that an indemnity claim is paid to any of the Radyne Indemnitees, no AeroAstro Shareholder will be liable in the aggregate for any indemnity claim or claims made under this Merger Agreement in excess of (i) the aggregate cash proceeds received by such AeroAstro Shareholder pursuant to the Merger plus (ii), for Xxxx Xxxxxxx, the aggregate cash proceeds received by him from the sale of any Merger Shares, net of reasonable and customary brokerage commissions actually incurred by Xxxx Xxxxxxx in connection with such sale or sales, and (iii) the number of Merger Shares, if any, held by him as of such date, multiplied by the Share Closing Price.

(k) Following the Effective Time, no AeroAstro Shareholder shall make any claim for indemnification against AeroAstro by reason of the fact that he, she, or it was a director or officer of AeroAstro (whether such claim is pursuant to any statute, charter document, bylaw, agreement, or otherwise) with respect to any indemnity claim brought by Radyne against such AeroAstro Shareholder pursuant to this Section 8.2.

8.3 Radyne’s Agreement to Indemnify. Subject to the limitations in this Article 8, Radyne hereby agrees to indemnify and hold harmless the AeroAstro Shareholders and their agents from and against all Losses asserted against or incurred by the AeroAstro Shareholders or their agents resulting from a breach of any covenant, agreement, representation or warranty of Radyne or Merger Sub contained in this Agreement or the exhibits hereto. Radyne will not be obligated to indemnify the AeroAstro Shareholders or any of their agents for any Loss except to the extent that such Loss, alone or when aggregated with other Losses, exceeds the Indemnity Basket. The Indemnity Basket will not apply under this Section 8.3 in the event any Loss is based on any intentional or deliberate misrepresentation or omission of Radyne or Merger Sub. AeroAstro and the AeroAstro Shareholders agree that any claim for indemnification against Radyne under this Article 8 shall be made solely through the Shareholder’s Representative, and that any and all actions with respect to the rights of the AeroAstro Shareholders under this Article 8 and the Escrow Agreement shall be exercised solely through the Shareholder’s Representative.

8.4 Notice of Claim. Any party who has a claim which would give rise to liability pursuant to this Article 8 shall give to all other parties and the escrow agent under the Escrow Agreement prompt notice of such claim, together with a reasonable description thereof; provided, that Radyne and AeroAstro shall provide such notice only to the Shareholders’ Representative and the Escrow Agent under the Escrow Agreement. With respect to any claim by a third party which is covered by the indemnifications contained hereunder, the party obligated to indemnify shall have the right to assume the entire control of the defense, compromise or settlement thereof (including the selection of counsel), subject to the right of the indemnified party to participate (with counsel of its choice, but the fees and expenses of such additional counsel shall be at the expense of the indemnified party); provided, however, that such indemnifying party shall secure the consent of the indemnified party to any settlement, which consent shall not be unreasonably withheld, unless the amount of the settlement (together with other settlements) is below the Indemnity Basket. If an indemnified party defends any claim hereunder, such party shall use reasonable efforts in such defense to mitigate Losses arising thereunder, and shall not settle any claim without the consent of the indemnifying party, which shall not be unreasonably withheld; provided, that any consent by the Shareholders’ Representative shall constitute adequate consent on behalf of the AeroAstro Shareholders under this Section 8.4. Notwithstanding the foregoing, (a) if a claim seeks relief other than the payment of monetary damages; (b) if the subject matter of a claim relates to the ongoing business of the indemnified party (including without limitation, any relationship with continuing suppliers, customers or other persons or entities with whom the indemnified party does business), which claim, if decided against the indemnified party, could materially adversely affect the ongoing business or reputation of the indemnified party or its relationship to such other party; or (c) the indemnified party may not be fully indemnified with respect to such claim, then, in each such case, the indemnified party alone shall be entitled to contest and defend such claim in the first instance, but not settle such claim without the consent of the indemnifying party,

which consent will not be unreasonably withheld and, if the indemnified party does not contest, defend or settle such claim, the indemnifying party shall then have the right to contest and defend such claim, but not settle such claim without the consent of the indemnified party, which consent will not be unreasonably withheld.

8.5 Satisfaction of Obligations. If an indemnifying party becomes obligated to indemnify another party with respect to any claim for indemnification hereunder and the amount of liability with respect thereto shall have been finally determined, the indemnified party, and in the event the indemnified party is a AeroAstro Shareholder, the Shareholders’ Representative shall deliver a notice to the indemnifying party and the Escrow Agent demanding payment pursuant to the Escrow Agreement. Additional provisions regarding the procedures for indemnification are as set forth in the Escrow Agreement.

8.6 Duty to Mitigate. Each party hereto agrees to use commercially reasonable efforts to mitigate any Losses that form the basis of any claim for indemnification under this Article 8, provided however, that nothing in this Section 8.6 shall require Radyne or AeroAstro to pursue insurance claims, except to the extent provided by Section 8.2(d)(ii), establish reserves, seek contribution from AeroAstro or any of its subsidiaries, or take any other similar action.

8.7 Reliance. The parties agree that reliance shall not be an element of any claim for misrepresentation or indemnification under this Agreement.

8.8 Exclusive Remedy. From and after the Closing, the sole recourse and exclusive remedy of Radyne and the AeroAstro Shareholders against each other arising out of this Agreement or any certificate delivered in connection with this Agreement, or otherwise arising from the transactions contemplated hereby, shall be to assert a claim for indemnification under the indemnification provisions of this Article 8, and each such party waives all other remedies it may have from and after the Closing, provided however, that nothing in this Section 8.8 shall preclude Radyne and the AeroAstro Shareholders from pursuing any equitable claim to which it or they may be entitled.

ARTICLE 9

TERMINATION, AMENDMENT AND WAIVER

9.1 Termination. This Agreement may be terminated at any time prior to the Effective Time:

(a) by mutual consent of a duly authorized officer of Radyne and AeroAstro and the Shareholders’ Representative;

(b) by Radyne or Merger Sub, on the one hand, or AeroAstro, on the other hand, if the other party breaches any of its material representations, warranties or covenants contained herein and, if such breach is curable, is not cured within 15 business days after notice thereof;

(c) by Radyne or Merger Sub, on the one hand, or AeroAstro, on the other hand, if obligations to close the transactions contemplated by this Agreement shall become incapable of satisfaction;

(d) by Radyne or Merger Sub, on the one hand, or AeroAstro, on the other hand, if the Merger shall not have been consummated by July 31, 2007 or such later date as may be agreed upon by Radyne, Merger Sub and the Shareholders’ Representative; provided, however, that the right to terminate this Agreement under this Section 9(d) shall not be available to any party whose failure to fulfill any obligation under this Agreement has been the cause of, or resulted in, the failure of the Effective Time to occur on or before July 31, 2007.

9.2 Effect of Termination. In the event of termination of this Agreement as provided in Section 9.1, this Agreement shall become void, and there shall be no liability or further obligation hereunder on the part of the parties or their respective security holders, officers or directors, except as set forth in Sections 6.1 and 6.3, and except for liability arising from a willful breach of this Agreement.

9.3 Amendment. This Agreement may not be amended except by an instrument in writing approved by Radyne, Merger Sub, AeroAstro and the Shareholders’ Representative.

9.4 Waiver. At any time prior to the Effective Time, Radyne or Merger Sub may extend the time for the performance of any of the obligations or other acts of any other party hereto, and AeroAstro may extend the time for performance of any of the obligations of Radyne or Merger Sub. In addition, Radyne and Merger Sub, on the one hand, and AeroAstro, on the other hand, may waive compliance with any of the agreements of any other party or with any conditions to its own obligations, in each case only to the extent such obligations, agreements and conditions are intended for its benefit.

ARTICLE 10

TAX MATTERS

The following provisions shall govern the allocation of responsibility as between Radyne and the Principal Shareholders for certain tax matters following the Effective Time:

10.1 Responsibility for Filing Tax Returns. Radyne shall properly and accurately prepare, or cause to be prepared, and file, or cause to be filed, on a timely basis (in each case, at its sole cost and expense and with respect to any period that includes a pre-closing period on a basis reasonably consistent with past practice of AeroAstro, unless otherwise required by applicable Tax laws) all Tax Returns of AeroAstro that are required to be filed after the Effective Time. With respect to any income Tax Return relating to a taxable period that began prior to the Effective Time, Radyne shall provide a draft copy of each such Tax Return to the Shareholders’ Representative for his review and approval at least 10 days prior to the due date for filing such return (or, if required to be filed within 10 days after the Effective Time, as soon as possible following the Effective Time). The Shareholders’ Representative shall provide its comments to Radyne at least five days prior to the due date of each such return and Radyne shall make any reasonable changes requested by the Shareholders’ Representative in good faith. Radyne shall timely pay, or cause to be timely paid, all Taxes with respect to AeroAstro shown to be due on such Returns.

10.2 Cooperation on Tax Matters. Radyne, AeroAstro and the Principal Shareholders (through the Shareholders’ Representative) shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns pursuant to this Article 10 and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.

10.3 Control of Tax Proceedings. If any claim, suit or proceeding shall be made by any taxing authority that could give rise to an additional payment of Taxes, the party responsible for the payment of such Taxes shall control all proceedings arising in connection with such claim, suit or proceeding; provided, however, that if the subject matter of a claim, suit or proceeding relates to the ongoing business of AeroAstro (including without limitation, its employees, suppliers, customers or other persons or entities with whom AeroAstro does business), which claim, suit or proceeding, if decided against AeroAstro, could materially adversely affect the ongoing business or reputation of AeroAstro or its relationship with such party after the Effective Time, then Radyne or AeroAstro, at their election, shall be entitled to contest, defend and settle such claim, suit or proceeding; provided further that neither Radyne nor AeroAstro shall be permitted to settle any such proceeding without the written consent of the Shareholders’ Representative if such settlement would require the payment of an indemnity by the Principal Shareholders, which shall not be unreasonably withheld, unless the amount of the settlement, together with other settlement(s), is below the Indemnity Basket. For purposes of the foregoing, the Shareholders’ Representative shall be deemed the party responsible for any Taxes the payment of which would result in a claim against the Escrow Fund.

ARTICLE 11

GENERAL PROVISIONS

11.1 Public Statements. Except as required by applicable law, rule or regulation, including of the NASDAQ Stock Market, prior to the Effective Time, no party shall make any public announcement or statement with respect to the Merger, this Agreement or any related transaction without the approval of the other parties, which approval will not be unreasonably withheld. Each party agrees to consult with the other parties prior to issuing any such public announcement or statement. The Parties acknowledge that, after the execution and delivery of this Agreement, Radyne will issue a press release and file a report on Form 8-K with the Securities & Exchange Commission announcing the signing of this Agreement and the transactions contemplated thereunder in accordance with rules and regulations promulgated under the Securities Exchange Act of 1934, as amended.

11.3 Dispute Resolution. All claims, disputes and other matters in controversy (herein called a “Dispute”) arising directly or indirectly out of or related to this Agreement, or the breach thereof, whether contractual or noncontractual, and whether during the term or after the termination of this Agreement, will be resolved exclusively according to the procedures set forth in this Section 11.3.

(a) Negotiation. The parties will attempt to settle Disputes arising out of or relating to this Agreement, or the breach thereof, by a meeting of two designated representatives of each party within five days after a request by either of the parties to the other party asking for the same.

(b) Mediation. If such Dispute cannot be settled at such meeting, either party within five days of such meeting may give a written notice (a “Dispute Notice”) to the other

party setting forth the nature of the Dispute. The parties will attempt in good faith to resolve the Dispute by mediation in Fairfax County, Virginia under the Commercial Mediation Rules of AAA in effect on the date of the Dispute Notice. The parties will select a person who will act as the mediator under this subsection (b) within 60 days of the date of this Agreement. If the Dispute has not been resolved by mediation as provided above within 30 days after delivery of the Dispute Notice, then the Dispute will be determined by arbitration in accordance with the provisions of subsection (c) below.

(c) Arbitration. Any Dispute that is not settled through mediation as provided in subsection (b) above will be resolved by arbitration in Fairfax County, Virginia, governed by the Federal Arbitration Act, 9 U.S.C. § 1 et seq., and administered by the AAA under its Commercial Arbitration Rules in effect on the date of the Dispute Notice, as modified by the provisions of this subsection (c), by a single arbitrator. The arbitrator selected, in order to be eligible to serve, will be a lawyer with at least 15 years experience specializing in business matters. In the event the parties cannot agree on a mutually acceptable single arbitrator from the list submitted by the AAA, AAA will appoint the arbitrator who will meet the foregoing criteria. The arbitrator will base the award on applicable law and judicial precedent and, unless both parties agree otherwise, will include in such award the findings of fact and conclusions of law upon which the award is based. Judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof.

(d) Judicial Review; Injunctive Relief. Notwithstanding the foregoing or anything in this Agreement to the contrary:

(i) Upon the application by either party to a court for an order confirming, modifying or vacating the award, the court will have the power to review whether, as a matter of law based on the findings of fact determined by the arbitrator, the award should be confirmed, modified or vacated in order to correct any errors of law made by the arbitrator. In order to effectuate such judicial review limited to issues of law, the parties agree (and will stipulate to the court) that the findings of fact made by the arbitrator will be final and binding on the parties and will serve as the facts to be submitted to and relied on by the court in determining the extent to which the award should be confirmed, modified or vacated; and

(ii) Either party will have the right to apply to any court for equitable relief to specifically enforce their rights under this Agreement and the other agreements contemplated by this Agreement, including but not limited to a party’s obligation to close the transaction and to honor the confidentiality provisions contained in this Agreement.

(e) Costs and Attorneys’ Fees. If either party fails to proceed with mediation or arbitration as provided herein or unsuccessfully seeks to stay such mediation or arbitration, or fails to comply with any arbitration award, or is unsuccessful in vacating or modifying the award pursuant to a petition or application for judicial review, the other party will be entitled to be awarded costs, including reasonable attorneys’ fees, paid or incurred by such other party in successfully compelling such arbitration or defending against the attempt to stay, vacate or modify such arbitration award and/or successfully defending or enforcing the award.

(f) Tolling of Statute of Limitations. All applicable statutes of limitations and defenses based upon the passage of time will be tolled while the procedures specified in this Section 11.3 are pending. The parties will take such action, if any, required to effectuate such tolling.

11.4 Interpretation. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. References to Sections and Articles refer to sections and articles of this Agreement unless otherwise stated. Words such as “herein,” “hereinafter,” “hereof,” “hereto,” “hereby” and “hereunder,” and words of like import, unless the context requires otherwise, refer to this Agreement (including the exhibits and attachments hereto). As used in this Agreement, the masculine, feminine and neuter genders shall be deemed to include the others if the context requires. The term “Agreement” means collectively this Agreement and the agreements, certificates and other documents delivered hereunder. For purposes of this Agreement, AeroAstro means AeroAstro and its subsidiaries, where appropriate (including, without limitation.

11.5 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated and the parties shall negotiate in good faith to modify this Agreement to preserve each party’s anticipated benefits under this Agreement.

11.6 Miscellaneous. This Agreement (together with all other documents and instruments referred to herein): (a) constitutes the entire agreement, and supersedes all other prior agreements, representations, warranties and undertakings, both written and oral, among the parties, with respect to the subject matter hereof; (b) is not intended to confer upon any other person any rights or remedies hereunder; (c) shall not be assigned by operation of law or otherwise except that this Agreement may be assigned by operation of law to any corporation with or into which Radyne may be merged or otherwise sold, including through sale of assets or stock; and (d) shall be governed in all respects, including validity, interpretation and effect, by the internal laws of the State of Delaware, without giving effect to the principles of conflict of laws thereof.
