This SERIES A CONVERTIBLE PREFERRED PARTICIPATING STOCK AND WARRANT PURCHASE AGREEMENT (the “Agreement”) is made as of the 22nd day of November, 2005 by and among Navtech, Inc., a Delaware corporation (the “Company”) and, the investors listed on Exhibit A hereto (each of whom individually is referred to herein as an “Investor” and collectively as the “Investors”).

In consideration of the mutual promises and covenants contained in this Agreement, the parties hereto agree as follows:

1.             Authorization of Preferred Stock; Purchase and Sale of Preferred Stock; Authorization of Warrants; Closing.

1.1.          Authorization of Preferred Stock.  The Company has authorized the issuance and sale of up to 1,600,000 shares of its Series A Convertible Participating Preferred Stock, $0.01 par value per share (the “Series A Preferred Stock”) to be issued under this Agreement.  The rights, privileges, and preferences of the Series A Preferred Stock are as set forth in the Company’s Certificate of Designation (the “Certificate of Designation”) in the form attached to this Agreement as Exhibit B, which the Company shall adopt and file with the Secretary of State of the State of Delaware on or before the date of the Closing (as defined below).

1.2.          Authorization of Warrants.  The Company has authorized the issue and sale of its warrants (herein, together with any warrants issued in exchange therefor or replacement thereof called the “Warrants”) evidencing the rights to acquire an aggregate of 100,000 shares (subject to adjustment) of Common Stock (as defined below).  The Warrants shall be exercisable at a price of $3.00 per share and shall be substantially in the form attached to this Agreement as Exhibit C.

1.3.          Purchase and Sale of the Preferred Stock and Warrants; Reservation of Common Stock.  Subject to the terms and conditions of this Agreement and on the basis of the representations and warranties set forth herein, the Company agrees to sell to the Investors, and each such Investor, severally and not jointly, agrees to purchase from the Company at the Closing (as defined below) (a) the number of shares of Series A Preferred Stock set forth opposite such Investor’s name on Exhibit A hereto, and (b) for no additional consideration, a Warrant initially exercisable for the number of shares of Common Stock set forth opposite such

Investor’s name on Exhibit A hereto.  The sale of the Series A Preferred Stock and the Warrants to each Investor hereunder shall constitute a separate sale.  The Company has authorized and reserved and covenants to continue to reserve, free of preemptive rights and other preferential rights, a sufficient number of its previously authorized but unissued shares of Common Stock, $0.001 par value per share (the “Common Stock”) to satisfy the rights of conversion of the holders of the Series A Preferred Stock and the rights of exercise of the holders of the Warrants.  Any shares of Common Stock issuable upon conversion of the Series A Preferred Stock shall be referred to in this Agreement as “Converted Shares”.  The shares of Series A Preferred Stock issued to the Investors pursuant to this Agreement and the Converted Shares shall be referred to in this Agreement as the “Shares.”  The Warrants issued pursuant to this Agreement and the Shares shall be referred to in this Agreement as the “Securities”.

1.4.          Purchase Price and the Closing.  The purchase and sale of the Securities shall take place at a Closing to be held at the offices of Choate, Hall & Stewart LLP, Two International Place, Boston, Massachusetts  02110, on such date and at such time as may be mutually agreed upon by the parties (the “Closing”).  The aggregate purchase price of the Series A Preferred Stock being purchased by each Investor at the Closing is set forth opposite such Investor’s name on Exhibit A under the heading “Aggregate Purchase Price”.  The Closing shall take place concurrently with the execution and delivery of this Agreement or at such other time as the parties shall mutually agree.  At the Closing, the Company will deliver to each of the Investors purchasing Securities a certificate or certificates, registered in such Investor’s name or such name as otherwise directed by such Investor, representing the number of Shares and Warrants to be acquired by such Investor pursuant to this Agreement against payment of the purchase price thereof by wire transfer, by check payable to the Company or such other form of payment acceptable to such Investor and the Company.

2.12.        Intellectual Property.

(a)           Except as listed in Section 2.12(a) of the Disclosure Schedule, the Company and each of its Subsidiaries owns, free and clear of any mortgage, pledge, security interest, encumbrance or other lien, or has the valid right to use all Intellectual Property (as defined below) used by it in its business as currently conducted or as proposed to be conducted.  To the best of the Company’s knowledge, no other person or entity (other than licensors of software that is generally commercially available and non-exclusive licensees of the Company’s or any of its Subsidiaries’ Intellectual Property in the ordinary course of the Company’s or any of its Subsidiaries’ business) has any rights to nor is claiming any rights to any of the Intellectual Property owned or used by the Company or any of its Subsidiaries, and, to the Company’s knowledge, no other person or entity is infringing, violating or misappropriating any of the Intellectual Property used by the Company or any of its Subsidiaries.  For purposes of this Agreement, “Intellectual Property” means all (i) patents and patent applications, (ii) copyrights and registrations thereof, (iii) mask works and registrations and applications for registration thereof, (iv) computer software, data and documentation, (v) trade secrets and confidential business information, whether patentable or unpatentable and whether or not reduced to practice, know-how, manufacturing and production processes and techniques, research and development information and data, copyrightable works, financial, marketing and business data, pricing and cost information, business and marketing plans and customer and supplier lists and information, (vi) trademarks, service marks, trade names, domain names and applications and registrations therefor and (vii) any exclusive licenses or other proprietary rights relating to any of the foregoing.

(d)           The Company and each of its Subsidiaries has taken reasonable precautions (i) to protect its rights in its Intellectual Property and (ii) to maintain the confidentiality of its trade secrets, know-how and other confidential Intellectual Property, and, to the best of the Company’s knowledge, there have been no acts or omissions (other than those made based on reasonable, good faith business decisions) by the officers, directors, shareholders and employees of the Company or any of its Subsidiaries the result of which would be to materially compromise the rights of the Company or any of its Subsidiaries to apply for or enforce appropriate legal protection of the Company’s or any of its Subsidiaries’ Intellectual Property.

(e)           All of the Intellectual Property owned by the Company or any of its Subsidiaries has been created by employees of the Company or its Subsidiaries within the scope of their employment by the Company or any of its Subsidiaries or by independent contractors of the Company or any of its Subsidiaries who have executed agreements expressly assigning all right, title and interest in such Intellectual Property to the Company or its Subsidiaries, as the case may be.  No portion of the Intellectual Property owned by the Company or any of its Subsidiaries was jointly developed with any third party.

8

2.14.        No Governmental Consent or Approval Required.  Based in part on the representations made by the Investors in Section 3 of this Agreement, other than federal or state securities law filings which have been made or which will be made in a timely manner and other than the filing of the Company’s Certificate of Designation (which is attached hereto as Exhibit B and will be filed on or before the date of the Closing), no authorization, consent, approval or other order of, declaration to, or filing with, any governmental agency or body is required for or in connection with the valid and lawful authorization, execution and delivery by the Company of any of the Transaction Documents for, or in connection with, the valid and lawful authorization, issuance, sale and delivery of the Shares.

(b)           Purchase Entirely for Own Account.  The Securities will be acquired for investment for such Investor’s own account and not with a view to the distribution of any part thereof.  Other than the transfer permitted by the Stockholders’ Agreement, such Investor does not have any contract, undertaking, agreement or arrangement with any Person to sell, transfer, or grant participations to such Person or to any third person, with respect to any of the Securities.

(c)           Restricted Securities.  Such Investor understands that the Securities may not be sold, transferred, or otherwise disposed of without registration under the 1933 Act, or an exemption therefrom, and that in the absence of an effective registration statement covering the Securities or an available exemption from registration under the 1933 Act, the Securities must be held indefinitely.  In the absence of an effective registration statement covering the Securities such Investor will sell, transfer, or otherwise dispose of the Securities only in a manner consistent with its representations and agreements set forth herein and the terms and conditions set forth in the Registration Rights Agreement.

(d)           Financial Condition.  Such Investor’s financial condition is such that it is able to bear the risk of holding the Securities for an indefinite period of time and can bear the loss of its entire investment in its Securities.

(e)           Experience.  Such Investor has such knowledge and experience in financial and business matters and in making high-risk investments of this type that it is capable of evaluating the merits and risks of the purchase of the Securities.

(f)            Receipt of Information.  Such Investor has been furnished access to the business records of the Company and such additional information and documents as such Investor has requested and has been afforded an opportunity to ask questions of and receive answers from representatives of the Company concerning the terms and conditions of this Agreement, the purchase of the Securities, the Company’s business, operations, market potential, capitalization, financial condition and prospects, and all other matters deemed relevant by such Investor.

12

(g)           Brokerage.  There are no claims for brokerage commissions or finder’s fees or similar compensation in connection with the transactions contemplated by this Agreement based on any arrangement or agreement made by or on behalf of such Investor, and such Investor agrees to indemnify and hold the Company and the other Investors harmless against any damages incurred as a result of any such claims.

(h)           Address.  Such Investor has provided the Company with its true and correct address.

3.2.          Legends.  It is understood that the certificates evidencing the Securities may bear substantially the following legends:

(a)           “These securities have not been registered under the Securities Act of 1933.  They may not be sold, offered for sale, pledged or hypothecated in the absence of a registration statement in effect with respect to the securities under such Act or an exemption from such registration (including pursuant to Rule 144 or Rule 144A of such Act).”

(b)           Any legend required by the laws of any applicable jurisdiction.

3.3.          Confidentiality.  Each of the Investors covenants and agrees that he, she or it will keep confidential and will not disclose, divulge or use for any purpose other than to monitor his, her or its investment in the Company any confidential, proprietary or secret information which such Investor may obtain from the Company pursuant to financial statements, reports or other materials submitted by the Company to such Investor pursuant to this Agreement or any other Transaction Document, or pursuant to visitation or inspection rights granted hereunder or thereunder (“Confidential Information”).  Notwithstanding the preceding sentence, each Investor may (a) disclose Confidential Information to the extent required by law or governmental order or regulation, or when required by a subpoena or other process, provided that such Investor first gives the Company advance notice of such disclosure as soon as practicable, (b) disclose Confidential Information to the extent necessary to enforce this Agreement, (c) disclose Confidential Information to its attorneys, accountants, consultants and other professionals to the extent necessary to obtain their services in connection with its investment in the Company, and (d) disclose Confidential Information as may be required by any prospective purchaser of any Securities from such Investor, provided that such prospective purchaser shall first execute a confidentiality and non-disclosure agreement in form acceptable to counsel for the Company.  An Investor may also disclose Confidential Information to any affiliate of such Investor provided that the requirements of this subsection shall in turn be binding on any such affiliate, or to a partner, member, shareholder or subsidiary of such Investor, and further provided that such partner, member, shareholder or subsidiary agrees to be bound by the provisions of this subsection.

6.             Preemptive Right of Purchase.

6.1.          Grant.  For so long as an Investor shall hold Series A Preferred Stock, the Company hereby grants to each such Investor, the right to purchase all or part of such Investor’s pro rata share of New Securities (as defined below) which the Company, from time to time, proposes to sell and issue.  An Investor’s pro rata share, for purposes of this purchase right, is the ratio of the number of Investors’ Common Shares (as defined below) which such Investor owns or has the right to acquire from the Company to the total number of shares of Common Stock then outstanding, on a fully diluted and as converted basis.

6.2.          Preemptive Right Definitions.  For the purpose of this Section 6, the term “Investors’ Common Shares” shall mean the Common Stock issued or issuable to the Investors upon the Conversion of the Series A Preferred Stock and the term “New Securities” shall mean any capital stock of the Company whether now authorized or not, and rights, options or warrants

16

to purchase capital stock, and securities that in any way rank senior to the Common Stock; provided that the term “New Securities” does not include Series A Preferred Stock.

6.3.          Notice.  In the event the Company proposes to undertake an issuance of New Securities, it shall give each Investor written notice of its intention, describing the type of New Securities and the price and the terms upon which the Company proposes to issue the same.  Each Investor shall have 20 business days from the date of receipt of any such notice to agree to purchase up to the Investor’s pro rata share of such New Securities for the price and upon the terms specified in the notice by giving written notice to the Company and stating therein the quantity of New Securities to be purchased.

6.4.          Sale.  In the event any Investor fails to exercise in full such Investor’s purchase right, the Company shall have 90 days thereafter to sell the New Securities with respect to which such Investor’s option was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice.  To the extent the Company does not sell all the New Securities offered within said (90) day period, the Company shall not thereafter issue or sell such New Securities without first again offering such securities to each Investor in the manner provided above.

6.5.          Limitation.  The Company shall not have any obligation under this Section 6 to any Person that is not an “accredited investor”, as such term is used in Regulation D under the Securities Act of 1933, as amended.

6.6.          Transfer.  Each Investor shall have the right to assign its rights to purchase all or any New Securities hereunder to an Affiliate, provided that such investor has transferred its Series A Preferred Stock to such Affiliate pursuant to and in accordance with the terms of Section 7.11 of this Agreement.

6.7.          Retrospective Effect of Preemptive Right of Purchase.  The Company may proceed with the issuance of New Securities without first following procedures in Section 6.1 through Section 6.5 above, provided, that (i) the purchaser of such New Securities agrees in writing to take such New Securities subject to the provisions of this Section 6.7, and (ii) within ten (10) days following the issuance of such New Securities, the Company undertakes steps substantially similar to those in Section 6.1 through Section 6.5 above to offer to all Investors the right to purchase from the Company a pro rata portion of such New Securities or equivalent at the same price and terms applicable to the purchaser’s purchase thereof so as to achieve substantially the same effect from a dilution protection standpoint as if the procedures set forth in Section 6.1 through Section 6.5 have been followed prior to the issuance of such New Securities.

7.             Miscellaneous.

7.1.          Certain Defined Terms.  As used in this Agreement, the term “Person” shall mean an individual, corporation, trust, partnership, limited liability company, joint venture,

17

unincorporated organization, government agency or any agency or political subdivision thereof, or other entity, and the terms “knowledge,” “known,” “awareness,” “aware,” and similar expressions, when used with reference to the Company, refer to the actual knowledge or awareness of David Strucke and Gordon Heard.  As used in this Agreement, each of the following terms is defined in the Section of this Agreement indicated below:
