PURCHASE AGREEMENT AND SECOND AMENDMENT
TO NOTE PURCHASE AGREEMENT

PURCHASE AGREEMENT AND SECOND AMENDMENT TO NOTE PURCHASE AGREEMENT, dated as of August 28, 2007 (this “Second Amendment”), by and among Navtech Systems Support Inc., an Ontario corporation (the “Company”), Navtech, Inc., a Delaware corporation (“Parent”), ABRY Mezzanine Partners, L.P., a Delaware limited partnership (“AMP”), and ABRY Investment Partnership, L.P., a Delaware limited partnership (“AIP” and, together with AMP, the “Purchasers”).

INTRODUCTION

The Company and the Purchasers are parties to a Note Purchase Agreement dated as of November 22, 2005, as amended by that certain First Amendment to Note Purchase Agreement dated February 26, 2007 (the “First Amendment”) and modified by that certain Waiver Agreement dated as of June 6, 2007 (as so amended and modified, the “Note Purchase Agreement”), pursuant to which, among other things, the Company issued certain Notes to the Purchasers. Each capitalized term that is used and not otherwise defined in this Second Amendment has the meaning that the Note Purchase Agreement assigns to that term. Each Purchaser is the holder of the Notes initially issued to it pursuant to the Note Purchase Agreement.

The Company has requested the holders of the Notes to (i) permit the Company to issue additional Tranche B Notes in the aggregate principal amount of up to $4.0 million, (ii) waive an Event of Default under Section 9A(v) of the Note Purchase Agreement resulting from the Company’s failure to timely deliver copies of certain financial information and officer compliance certificates to the holders of the Notes pursuant to and in accordance with section 4D of the Note Purchase Agreement, and (iii) amend certain terms of the Note Purchase Agreement, each as more fully set forth herein. In addition, the Company has requested that AMP purchase the additional Tranche B Notes described in clause (i) above. In consideration for AMP’s agreement to purchase such additional Tranche B Notes, Parent has agreed to issue to AMP a stock purchase warrant evidencing the right to purchase 0.60% of Parent’s common stock, par value $0.001 per share (the “Common Stock”), calculated on a fully-diluted basis assuming the conversion, exercise and exchange of all outstanding securities convertible into or exchangeable for shares of the Common Stock and as more fully described on the capitalization table of the Parent attached hereto as Schedule I.

The Company, Parent and the Purchasers have agreed to issue additional securities, amend certain terms of the Note Purchase Agreement and waive certain Events of Default under the Note Purchase Agreement upon the terms and conditions set forth in this Second Amendment.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company, Parent and the Purchasers hereby agree as follows:

1. Authorization, Purchase and Sale of Notes and Warrants.

(a) The Company has authorized the issuance and sale of an additional tranche of its 13.0% Senior Subordinated Notes due 2011 in an aggregate principal amount of up to $4.0 million, each in the form of the attached Exhibit A (the “2007 Tranche B Notes”), which shall consist of (i) a ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Note in the aggregate principal amount of $2.1 million to be issued as of the date hereof (the “2007 Tranche B Note-A”), and (ii) a ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Note in the aggregate principal amount of up to $1.9 million to be issued no later than August 22, 2008 (“2007 Tranche B Note-B”), which issuance of the ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Note-B shall be subject to the conditions set forth in Section 2 below; and

(b) Parent has authorized the issuance and sale of its stock purchase warrants evidencing the right to purchase up to 42,958 shares of Common Stock (herein, together with any stock purchase warrants issued in exchange therefor or replacement thereof, called the “2007 Warrants” and, together with the ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Notes, the “New Securities”). The 2007 Warrants are to be substantially in the form of Exhibit B attached hereto. The period during which the Warrants may be exercised and the amount to be paid upon exercise for the shares of Common Stock upon exercise are, among other things, set forth in the 2007 Warrants. The 2007 Warrants and the shares of Common Stock underlying the 2007 Warrants shall constitute (i) “Warrants” and “Warrant Shares” as such terms are defined in that certain Warrant Agreement dated as of November 22, 2005 by and among the Parent and the Purchasers (the “Warrant Agreement”), and (ii) “ABRY Warrants” as such term is defined in that certain Registration Rights Agreement dated November 25, 2007 by and among Parent, the Purchasers and the other investors set forth therein (the “Registration Rights Agreement”) and the holders of the 2007 Warrants shall be entitled to all of the rights and benefits, and shall be subject to any and all obligations, of a warrantholder under the Warrant Agreement and the Registration Rights Agreement. The Purchasers, the Company and Parent agree that the Transaction Agreements are hereby deemed amended in all respects as may be necessary in order to give effect to the foregoing sentence.

(c) The Company and Parent, respectively, agree to issue and sell to AMP, and AMP agrees to purchase, on the date hereof, the ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Note-A and the 2007 Warrants, for aggregate consideration equal to $2,100,000, payable by wire transfer of immediately available funds to an account specified by the Company. If the Company gives AMP a written notice requesting that AMP purchase the 2007 Tranche B Note-B (a “Purchase Notice”), then on the date specified in such Purchase Notice, the Company will sell to AMP, and AMP will purchase from the Company, the ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Note-B for aggregate consideration equal to initial

principal amount of the ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Note-B (which amount will be specified in the Purchase Notice and will not exceed $1,900,000), payable by wire transfer of immediately available funds to an account specified by the Company. The purchase and sale of the ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Note-B is referred to as the “2008 Closing”).

2. Conditions to the issuance of the ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Note-B. The obligation of the Purchasers to issue the 2007 Tranche B Note-B is subject to the following conditions:

(i) immediately before and after giving effect to the issuance of the 2007 Tranche B Note-B no Event of Default or Potential Event of Default shall exist and be continuing;

(ii) the Leverage Ratio, calculated as of the 2008 Closing Date and as if June 30, 2008 were the last day of the then most-recently-ended Fiscal Quarter (computed on a pro forma basis after giving effect to the issuance of the ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Note-B and any substantially concurrent application of the proceeds thereof to pay the contingent payment due and payable to SAS on August 31, 2008), shall not exceed 6.65 to 1.0;

(iii) receipt by the Purchasers of a certificate from the President or Chief Financial Officer of the Company certifying to the amount of the contingent payment due and payable to SAS on August 31, 2008;

(iv) not fewer than five (5) days shall have elapsed since the Company made the deliveries required by Section 4D(i) of the Note Purchase Agreement for the month ending on June 30, 2008;

(v) not fewer than twelve (12) business days (as that term is defined in Section 10H of the Note Purchase Agreement shall have elapsed since the Company delivered the Purchase Notice;

(vi) each of the representations and warranties set forth in Section 3 of this Second Amendment shall be true and correct as of the time of the 2008 Closing, as if made at such time; and

(vii) the Company shall have delivered to AMP a certificate to the effect that each of the conditions set forth in clauses (i), (ii) and (vi) above is satisfied.

3. Representations and Warranties. As a material inducement to enter into this Second Amendment (and, in the case of AMP, to agree to purchase the ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Notes), the Company and Parent hereby represent to the Purchasers as follows:

(a) Organization and Power. The Company is a corporation duly organized, validly existing and in good standing under the Laws of the Province of Ontario, Canada, Parent is a corporation duly organized, validly existing and in good standing under the Laws of the State of Delaware, and each is qualified to do business in

every jurisdiction in which the failure to so qualify might reasonably be expected to have a Material Adverse Effect.

(b) Capital Stock and Related Matters. All of the issued and outstanding Equity Securities of the Company are owned by the Parent, free and clear of any Lien (other than Permitted Liens), and not subject to any option or right to purchase any such shares. The attached Schedule I is a correct and complete description of the Equity Securities of Parent outstanding as of the date hereof, after giving effect to the issuance of the 2007 Warrants.

(c) Authorization; Non-contravention. The execution, delivery and performance of the New Documents (as defined below) to which the Company or Parent is a party and the issuance of the New Securities have been duly authorized by the Company and/or Parent, as applicable. Each of the New Documents to which the Company or Parent is a party constitutes a valid and binding obligation of the Company or Parent (as applicable), enforceable against it in accordance with its terms, except as may be limited by the equitable remedies of specific performance, other equitable remedies or principles or Laws governing creditors’ rights generally. Neither the execution and the delivery of any New Document nor the consummation of the transactions contemplated hereby or thereby (including the issuance of the New Securities), (i) violate any constitution, statute, regulation, rule, injunction, judgment, order, decree, ruling, charge, or other restriction of any Government Entity to which any member of the Company Group is subject, except to the extent that such violation could not reasonably be expected to have a Material Adverse Effect, or any provision of the constitutive documents or by-laws of the Company or any Subsidiary, or (ii) conflict with, result in a breach of, constitute a default under, result in the acceleration of, or create in any party the right to accelerate, terminate, or cancel, any material and written agreement, contract, lease, license or instrument to which any member of the Company Group is a party or by which it is bound or to which any of its assets is subject (or result in the imposition of any Lien upon any of its assets, other than Permitted Liens). No member of the Company Group is required to give any notice to, make any filing with, or obtain any authorization, consent, or approval of any Government Entity or any other Person for it to consummate the transactions contemplated by the New Documents, except for such as have been made or obtained and except as may be required by applicable Laws. The term “New Documents” means this Agreement, the Guaranty Acknowledgement, the ▇▇▇▇ ▇▇▇▇▇▇▇ ▇ Notes and the 2007 Warrants.

(d) No Material Adverse Change. Except as disclosed in the Public Reports, since the date of the Note Purchase Agreement, there has been no Material Adverse Effect.

(e) SEC Filings. Since November 22, 2005, Parent has made all filings with the SEC that it has been required to make under the Securities Act and the Exchange Act (such reports collectively, the “Public Reports”, and each a “Pubic Report”).

Each of the Public Reports as of its date complied with the Securities Act or the Exchange Act, as applicable, and the rules promulgated thereunder or pursuant thereto in all material respects. None of the Public Reports, as of their respective dates, contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading, except to the extent that a Public Report was corrected by a Public Report subsequently filed with the SEC. Each required form, report and document containing financial statements that Parent has filed with or submitted to the SEC since that date of the Note Purchase Agreement was accompanied by the certifications required to be filed or submitted by the Parent’s chief executive officer and chief financial officer pursuant to the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules and regulations promulgated under such act or the Exchange Act, and no such certificate has been modified or withdrawn. Neither any member of the Company Group nor any of its officers has received notice from any Governmental Entity questioning or challenging the accuracy, completeness, content, form or manner of filing or submission of such certifications.

4. Amendment to Definition of Accrued Amount. The definitions of “Accrued Amount” and “Consolidated EBITDA” in Section 1A of the Note Purchase Agreement are hereby amended by deleting them in their entirety and replacing them with the following new definitions in the appropriate alphabetical order:

““Accrued Amount” means, for any Note at any time, the principal amount of such Note, plus accrued and unpaid interest thereon, provided, however, that for the purpose of calculating the Leverage Ratio in Section 4F, the Accrued Amount shall not include (i) interest on the Notes that has accrued since the most-recent interest payment date (as defined below) that the Company is required to pay in cash on the next interest payment date, unless any interest on the Notes that is then due and payable has not been paid or (ii) interest on the Notes that was previously deferred, which the Company has paid in cash pursuant to and in accordance with the terms of Section 1 of the Notes. As used in the preceding sentence, “interest payment date” means any May 1 or November 1.

“Consolidated EBITDA” means, for any 12-month period, the Consolidated earnings of the Company Group for such period before any provision for (i) interest expense paid in cash for such period, (ii) amounts in respect of depreciation and amortization for such period and (iii) taxes in respect of income and profits, including without limitation, all taxes based on taxable income and all other corporate franchise, capital stock, net worth and value added taxes assessed by any state, local, provincial and foreign governments for such period, minus distributions and one time gains during such period, plus any non-recurring extraordinary expenses, the exclusion of which from the calculation of operating income has not been objected to by the Company Group’s independent auditors or the addition of which the Majority Noteholders have approved for purposes of computing Consolidated EBITDA, all of the foregoing determined on a Consolidated basis in accordance with GAAP; provided that for the purposes of calculating Consolidated EBITDA hereunder, any income or losses associated with foreign exchange rates

and any expenses associated with the issuance or exercise of any stock option, warrant or similar Equity Security issued by the Company Group shall be disregarded.”

5. Amendment of Maximum Leverage Ratio Provision. Section 4F(ii) of the Note Purchase Agreement is hereby amended and restated in its entirety as follows:
