3.                         POSITION,
DUTIES AND RESPONSIBILITIES.  During the period of the employment

employment, the Option would vest with respect to 25% of the shares subject
thereto on the first anniversary of the Effective Date, and with respect to an
additional 1/48th of the shares subject thereto on each monthly anniversary
thereafter, such that the entire Option would be vested on the fourth

stock option agreement in a form prescribed by Accuray, which you will be
required to sign as a condition to receiving the Option (the “Option Agreement”).

STOCK UNITS.  We will recommend to the Compensation
Committee of the Board of Directors that you be granted 8,000 restricted stock

approval of the grant and its terms by the Compensation Committee.  Subject to the your continued service as an
Employee through the applicable vesting date, twenty-five percent (25%) of the
RSUs shall vest on the first anniversary of the Effective Date and an

Payment in respect of any
RSUs that vest in accordance with the grant agreement will be made to you in
whole shares of our common stock as soon as practicable after the applicable
vesting date, but in no event later than 60 days after such vesting date.  The RSUs will be subject to the terms and
conditions of the Incentive Plan and a restricted stock unit grant agreement in
a form prescribed by Accuray, which you will be required to sign as a condition
to receiving the RSUs (the “RSU Agreement”).

employment (from Effective Date through July 2, 2010) and your employment with
the Company is terminated by the Company without Cause or by you for Good
Reason, in each case within the twelve (12) month period immediately following

common stock and RSUs shall become fully vested and exercisable immediately
prior to the effective time of the termination of your employment.

(c)              Notwithstanding the foregoing, your right to
receive the payments and benefits set forth in this Section 9 is conditioned on
and subject to your execution and non-revocation of a general release of claims
against the Company and its affiliates, in a form prescribed by the

10.                   CODE
SECTION 280G.

(a)              In the event it shall be determined that any
payment or distribution to you or for your benefit which is in the nature of
compensation and is contingent on a change in the ownership or effective
control of the Company or the ownership of a substantial portion of the assets
of the Company (within the meaning of Section 280G(b)(2) of the Code), whether
paid or payable pursuant to this letter or otherwise (a “Payment”), would constitute a “parachute
payment” under Section 280G(b)(2) of the Code and would be subject to the
excise tax imposed by Section 4999 of the Code (together with any interest or
penalties imposed with respect to such excise tax, the “Excise Tax”), then the Payments shall be
reduced to the extent necessary so that no portion thereof shall be subject to
the excise tax imposed by Section 4999 of the Code but only if, by reason of

after-tax benefit received by you if no such reduction was made.  For purposes of this Section 10(a), “net
after-tax benefit” shall mean (i) the Payments which you receive or are
then entitled to receive from the Company that would constitute “parachute

Payments calculated at the maximum marginal income tax rate for each year in
which the Payments shall be paid to you (based on the rate in effect for such
year as set forth in the Code as in effect at the time of the first payment of
the foregoing), less (iii) the amount of Excise Taxes imposed with respect
to the Payments.

(b)             All determinations required to be made under

 4

that the Accounting Firm’s determination shall be made based upon “substantial
authority” within the meaning of Section 6662 of the Code.  The Accounting Firm shall provide its
determination, together with detailed supporting calculations and
documentation, to you and the Company within 15 business days following the
date of termination of your employment, if applicable, or such other time as
requested by you (provided that you reasonably believe that any of the Payments
may be subject to the Excise Tax) or the Company.  All fees and expenses of the Accounting Firm
shall be borne solely by the Company.

11.                   RESTRICTIVE

cooperate with the taking of any such actions by any other individual or

for such breach would not be readily calculable, and that the Company would not

fees and expenses associated with such arbitration to the extent permitted by
applicable law.

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 2007 Tranche B 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 2007 Tranche B 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 2007
Tranche B 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 2007 Tranche B 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 2007 Tranche B 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 2007 Tranche B
Note-B for aggregate consideration equal to initial

 2
 

principal
amount of the 2007 Tranche B 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 2007 Tranche B
Note-B is referred to as the “2008 Closing”).

2.             Conditions to the
issuance of the 2007 Tranche B 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 2007 Tranche B 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 2007 Tranche B 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

 3
 

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 2007 Tranche
B 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”).  

 4
 

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 Sarbanes-Oxley
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

 5
 

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:

“(ii)         Maximum Leverage Ratio.  The Company shall not permit the Leverage
Ratio for the last day of any Fiscal Quarter to exceed the maximum Leverage
Ratio specified below for such Fiscal Quarter:

6.             Amendment to

Section 4D of the Note Purchase Agreement is hereby amended and restated
in its entirety as follows:

“4D Financial Statements and Other Information.  So long as any Notes remain outstanding, the
Company shall deliver, whether or not the Parent is then required to file
reports with the SEC pursuant to the terms of the Exchange Act, to each holder
of Notes:

 6

(iii)          within

(iv)          promptly
upon receipt thereof, any additional reports, management letters or other

(v)           at

and shall fairly present in all material respects the financial position of the
companies being reported upon as of the dates and for the periods stated
therein, subject in the case of the unaudited financial statements to changes
resulting from normal year-end adjustments.”

7.             Waiver of Existing
Events of Default.  Certain Events of
Default have arisen under the Note Purchase Agreement as a result of the
Company’s failure to timely deliver (i) copies of the monthly financial
statements and officer certifications required pursuant to and in accordance
with Section 4D(i) of the Note Purchase Agreement for each month from and after
June 6, 2007 to the date hereof, and (ii) copies of the quarterly financial
statements, compliance certificates and officer certifications required
pursuant to and in accordance with Section 4D(ii) of the Note Purchase
Agreement for each Fiscal Quarter from and after June 6, 2007 to the date

Existing Events of Default.  The waiver
of the Existing Events of Default shall relate only to the specific instances
involved for the specific time periods stated in connection with the Existing
Events of Default and shall not apply to any other Events of Default which may
now exist or may hereafter arise under the Note Purchase Agreement.  Nothing contained herein shall constitute a
consent to any other action of the same or similar nature that the Company has heretofore
or may hereafter take or omit to take under the Note Purchase Agreement.

8.             Payment of Closing
Fees.  The Company shall pay, (i) in
immediately available funds on the date hereof, a fee to AMP of $115,000 (the “Second
Amendment Closing Fee”), and (ii) in immediately available funds upon the
issuance of the 2007 Tranche B Note-B, a

 8
 

fee in the amount equal
50 basis points of the principal amount of the 2007 Tranche B Note-B.  In addition, the Company will reimburse the
Purchasers for the reasonable and documented fees and expenses of their legal
counsel in connection with the transactions contemplated by the First Amendment
and the New Documents.

9.             Conditions to
Effectiveness of Second Amendment. 
This Second Amendment shall be effective upon the first date upon which
the following conditions shall have been satisfied to the Purchasers’
reasonable satisfaction:

(i)            Receipt by the
Purchasers of this Second Amendment duly executed by the Company and Parent,
and receipt by the Purchasers of an Acknowledgement of Continuing Guaranty and
Consent by the members of the Company Group other than the Company,

Registration Rights Agreement, in form and substance reasonably acceptable to
the Purchasers,

(iv)          Receipt by the
Purchasers of a certificate of the Secretary or an Assistant Secretary of the

Second Amendment and the consummation of the transactions contemplated hereby,
and (ii) as to the incumbency and genuineness of the signature of each

paid in full the Second Amendment Closing Fee; and

(vi)          Receipt by the
Purchasers of such other documents, instruments and agreements as the

10.           Miscellaneous.  The Company and the Purchasers agree that (i)
this Second Amendment and the 2007 Tranche B Notes and the 2007 Warrants to be
issued as provided in Section 1 of this Second Amendment constitute
Transaction Agreements, including for purposes of Section 10 of the Note
Purchase Agreement, and (ii) the 2007 Tranche B Notes constitute Notes for the
purposes of the Note Purchase Agreement and the other Transaction Agreements.  The Purchasers and the Company agree that the
Transaction Agreements are hereby deemed amended in all respects as may be
necessary in order to give effect to the

 9
 

foregoing sentence.  ALL ISSUES AND QUESTIONS
CONCERNING THE CONSTRUCTION, VALIDITY, ENFORCEMENT AND INTERPRETATION OF THIS SECOND
AMENDMENT AND THE ANNEXES, EXHIBITS AND SCHEDULES HERETO SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF
MASSACHUSETTS, WITHOUT GIVING EFFECT TO ANY CHOICE OF LAW OR CONFLICT OF LAW
RULES OR PROVISIONS (WHETHER OF THE COMMONWEALTH OF MASSACHUSETTS OR ANY OTHER
JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION
OTHER THAN THE COMMONWEALTH OF MASSACHUSETTS. 
IN FURTHERANCE OF THE FOREGOING, THE INTERNAL LAW OF THE COMMONWEALTH OF
MASSACHUSETTS SHALL CONTROL THE INTERPRETATION AND CONSTRUCTION OF THIS SECOND AMENDMENT
(AND ALL ANNEXES, SCHEDULES AND EXHIBITS HERETO), EVEN THOUGH UNDER THAT
JURISDICTION’S CHOICE OF LAW OR
CONFLICT OF LAW ANALYSIS, THE SUBSTANTIVE LAW OF SOME OTHER JURISDICTION WOULD
ORDINARILY APPLY.  ALL JUDICIAL
PROCEEDINGS BROUGHT AGAINST ANY PARTY HERETO WITH RESPECT TO THIS SECOND AMENDMENT
SHALL BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN
BOSTON, MASSACHUSETTS.  BY EXECUTING AND
DELIVERING THIS SECOND AMENDMENT, THE COMPANY AND EACH HOLDER OF NOTES,
WARRANTS AND UNDERLYING COMMON STOCK, ACCEPTS THE NONEXCLUSIVE JURISDICTION OF
THE AFORESAID COURTS, AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT
RENDERED THEREBY IN CONNECTION WITH THIS SECOND AMENDMENT.  THE COMPANY AND EACH HOLDER OF NOTES,
