The Closing Balance Sheet shall be prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) consistently applied except that it shall exclude estimated taxes payable or refundable for the pre-Closing Tax periods, and deferred tax liabilities or assets. If Buyer objects to the Shareholders Representative’s calculations of the Final Current Assets, the Final A/P and/or the Final Backlog, Buyer shall within fifteen (15) days after receipt thereof notify the Shareholders Representative of the same in writing, which such notice shall include the basis of such objection in reasonable detail and Buyer’s proposed modification of such calculations to the Shareholders Representative. If Buyer does not object to such calculation within such fifteen (15) day period, the Shareholders Representative’s calculation shall be final, conclusive and binding on the parties.

(b) If the Shareholders Representative disagrees with all or any portion of Buyer’s proposed modifications of the Final Current Assets, Final A/P and/or Final Backlog delivered by Buyer pursuant to Section 1.4(a), the parties shall negotiate in good faith to reach an agreement during the fifteen (15) day period following delivery of such proposed modification by Buyer.

The indemnified party shall endeavor to notify the indemnifying party in writing within thirty (30) business days of the indemnified party’s first receipt of notice of, or the indemnified party’s obtaining actual knowledge of, such claim, and in any event within such shorter period as may be necessary for the indemnifying party or parties to take appropriate action to resist such claim; provided, however, that the failure to notify or delay in notifying the Shareholder Representative or Buyer, as the case may be, will not relieve the indemnifying party of its obligations pursuant to Section 9.1(a) or (b), except to the extent that such claim is materially prejudiced as a result thereof. Such notice shall specify all facts known to the indemnified party giving rise to such indemnity rights and shall estimate (to the extent reasonably possible) the amount of potential liability arising therefrom. If the indemnifying party shall be duly notified of such dispute, the parties shall attempt to settle and compromise the same or may submit the same to arbitration in accordance with Section 15.3 below or, if unable or unwilling to do any of the foregoing, such dispute shall be settled by appropriate litigation, and any rights of indemnification established by reason of such settlement, compromise, arbitration or litigation shall promptly thereafter be paid and satisfied by those indemnifying parties obligated to make indemnification hereunder.

[***] Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission.

9.3 Right to Defend. If the facts giving rise to any claim for indemnification shall involve any actual or threatened action or demand by any third party against the indemnified party or any of its Affiliates, except as otherwise provided in this Section 9.3, the indemnifying party or parties shall be entitled (without prejudice to the indemnified party’s right to participate at its own expense through counsel of its own choosing), at their expense and through counsel of their own choosing, upon written notice to the indemnified party, and using counsel reasonably satisfactory to the indemnified party, to defend such claim in the name of the indemnifying party or parties, or any of them, or if necessary, in the name of the indemnified party, provided that the indemnifying party has unconditionally acknowledged to the indemnified party in writing its obligation to indemnify the Persons to be indemnified hereunder with respect to such third person claim and to discharge any cost or expense arising out of such investigation, contest or settlement. The indemnifying party must obtain the prior written consent of the indemnified party (which will not be unreasonably withheld) prior to entering into any settlement of any claim or proceeding or ceasing to defend any claim or Proceeding unless the proposed settlement involves only the payment of money damages and does not impose an injunction or other equitable relief on the indemnified party. Notwithstanding anything to the contrary in this Agreement, in connection with any third party claim, the indemnifying party shall not be entitled to assume control of such defense and shall pay the reasonable fees and expenses of counsel retained by the indemnified party if the indemnified party shall reasonably conclude that (i) the claim for indemnification relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation; (ii) the claim seeks an injunction or equitable relief against the indemnified party; (iii) the indemnified party reasonably believes an adverse determination with respect to the action, lawsuit, investigation, proceeding or other claim giving rise to such claim for indemnification would be detrimental to or injure the indemnified party’s reputation or future business prospects; (iv) upon petition by the indemnified party, the appropriate court rules that the indemnifying party failed or is failing to vigorously prosecute or defend such claim; (v) there is a threat of any relief other than solely monetary damages being granted, (vi) in the opinion of the indemnified party’s legal counsel, there is a conflict of interest between the indemnifying party and the indemnified party in the conduct of the defense of such third party claim or (vii) there are specific defenses available to the indemnified party which are different from or additional to those available to the indemnifying party and which could be materially adverse to the indemnifying party

9.4 Set-Off. Buyer shall be entitled to set-off (i) any amount that Buyer claims a Seller owes it under this Agreement against (ii) any amounts owed by Buyer to such Seller under this Agreement, including without limitation, any amounts owed and payable by Buyer pursuant to Section 1.2.

9.5 No Waiver. The representations and warranties of Sellers and the Company shall not be affected or deemed waived by reason of any investigation made by or on behalf of the Buyer (including but not limited to any of its representatives) or by reason of the fact that Buyer or any of its representatives knew or should have known that any such representation or warranty is or might be inaccurate.

10. SHAREHOLDERS REPRESENTATIVE.

10.1 Shareholders Representative Appointment and Duties. Kathy J. Osborne (or any successor thereto appointed in accordance with Section 10.2) (the “Shareholders Representative”), is hereby appointed the exclusive agent, proxy and attorney-in-fact for each Seller. The Shareholders Representative shall have the authority to act for and on behalf of Sellers, including, without limitation, (i) to consummate the transactions contemplated herein (with such modifications or changes therein as

to which the Shareholders Representative, in its sole discretion, shall have consented), (ii) to receive and deliver to Buyer surrendered certificates representing the Shares, (iii) to communicate to, and receive all communications and notices from, Buyer, (iv) to do each and every act, implement any decision and exercise any and all rights which Sellers are permitted or required to do or exercise under this Agreement or any documents delivered pursuant to this Agreement, (v) to execute and deliver on behalf of such Sellers any amendment or waiver hereto, (vi) to negotiate, settle, compromise and otherwise handle any post-closing adjustments and all claims for indemnification made by Buyer, (vii) to agree to, negotiate, enter into settlements and compromises of, and commence, prosecute, participate in, settle, dismiss or otherwise terminate, as applicable, any litigation, action, proceeding or investigation relating to the Company, the Shares, Sellers, this Agreement, the Transaction Documents or any of the transactions contemplated by this Agreement or the Transaction Documents, and to comply with orders of courts and awards of courts, mediators and arbitrators with respect to such litigation, action, proceeding or investigation, and (viii) to make, execute, acknowledge and deliver all such other agreements, guarantees, orders, receipts, endorsements, notices, requests, instructions, certificates, stock powers, letters and other writings, and, in general, to do any and all things and to take any and all actions that the Shareholders Representative, in its sole discretion, may consider necessary or proper or convenient in connection with or to carry out the transactions contemplated by this Agreement and the Transaction Documents. The Shareholders Representative shall, in this regard, have all of the rights and powers which Sellers would otherwise have, and Sellers agree that Buyer shall be entitled to rely exclusively upon all actions taken or omitted to be taken by the Shareholders Representative pursuant to this Agreement and any of the foregoing matters. The Shareholders Representative shall for all purposes be deemed the sole authorized agent of Sellers until such time as the agency is terminated. Each Seller agrees that such agency and proxy are coupled with an interest, are therefore irrevocable without the consent of the Shareholders Representative and shall survive the death, incapacity, bankruptcy, dissolution or liquidation of any Seller. All decisions and actions by the Shareholders Representative shall be binding upon all Sellers, and no such Seller shall have the right to object, dissent, protest or otherwise contest the same.

10.2 Resignation or Removal of the Shareholders Representative. The Shareholders Representative may be removed at any time upon a vote of Sellers holding a majority of the Shares (and, if after the Closing, as of immediately prior to the Closing). Subject to the appointment and acceptance of a successor Shareholders Representative as provided below, the Shareholders Representative may resign at any time thirty (30) days after giving notice thereof to Sellers. Upon any such removal or resignation, the retiring Shareholders Representative may, on behalf of Sellers, appoint a successor Shareholders Representative; provided, however, that if the retiring Shareholders Representative is unwilling or unable to appoint a successor Shareholders Representative, Sellers may appoint a successor Shareholders Representative by a vote of Sellers holding a majority of the Shares (and, if after the Closing, as of immediately prior to the Closing). Upon the acceptance of any appointment as the Shareholders Representative hereunder, such successor Shareholders Representative shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Shareholders Representative, and the retiring Shareholders Representative shall be discharged from its duties and obligations hereunder. After any retiring Shareholders Representative’s resignation or removal hereunder as the Shareholders Representative, the provisions of Section 10.3 shall continue in effect for such retiring Shareholders Representative’s benefit in respect of any actions taken or omitted to be taken by it while it was acting as the Shareholders Representative.

10.3 Liability of Shareholders Representative. The Shareholders Representative shall not incur any liability to Sellers with respect to any action taken in reliance upon any note, direction, instruction, consent, statement or other document believed by the Shareholders Representative to be genuinely and duly authorized, or for any other action or inaction in its capacity as the Shareholders Representative, excepting only the fraud or willful misconduct of the Shareholders Representative. The Shareholders Representative may, in all questions arising hereunder, rely on the advice of legal counsel and for anything done, omitted or suffered in good faith by the Shareholders Representative based on such advice, the Shareholders Representative shall not be liable to any Seller while acting in its capacity as Shareholders Representative. Each Individual Seller shall be liable, pro rata in accordance with such Individual Seller’s Indemnification Percentage, for any expenses (including, without limitation, reasonable attorneys’ fees and expenses) paid or incurred by the Shareholders Representative in connection with the performance of its obligations as Shareholders Representative, including in the defense of any indemnification claim brought against Sellers under Section 9.

(c) by either the Company or Buyer, either of whom may act, if there shall be any law or regulation that makes consummation of the transactions contemplated hereby illegal or otherwise prohibited or if consummation of the transactions contemplated hereby would violate any nonappealable final order, decree or judgment of any court or governmental body having competent jurisdiction;

(d) by the Company, provided the Company is not then in breach of any of its obligations hereunder, if either (i) Buyer fails to perform any covenant contained in this Agreement when performance thereof is due and does not cure the failure within twenty (20) days after the Company delivers written notice thereof, or (ii) any condition in Section 7.1 has not been satisfied and is not capable of being satisfied prior to the Termination Date; or

Schedule 1.2

Adjustments to Base Purchase Price

(a) Adjustments to Closing Cash Payment.

(i) Cash & Accounts Receivable = $1,600,000.

This Agreement contemplates that at the Closing the amount of cash will be $900,000 and the amount of accounts receivable (including unbilled receivables) will be $700,000. The Closing Cash Payment will be reduced by the exact amount (if any) that the sum of cash and accounts receivable is less than $1,600,000 and will be increased by the exact amount (if any) that the sum of cash and accounts receivable is more than $1,600,000.

(ii) Accounts Payable = $100,000

This Agreement contemplates (A) that prior to the Closing the final installments totaling [***] for the Loquendo license (LDE-072909MBMeridian) shall have been paid; and (B) at the Closing the amount of accounts payable will be $100,000. The Closing Cash Payment will be reduced by the exact amount (if any) that the total accounts payable exceeds $100,000 and will be increased by the exact amount (if any) that the total accounts payable is less than $100,000.

(iii) Backlog Adjustment

This Agreement contemplates that at the Closing total Backlog will be [***]. The Closing Cash Payment will be reduced by an amount equal to 15% of the amount that Backlog is less than [***].

(iv) Unpaid Sick Leave and Vacation

This Agreement contemplates that the liability for earned but unpaid Sick Leave and Vacation shall not exceed [***] at the Closing. The Closing Cash Payment will be reduced by an amount equal to the amount that such liability exceeds [***].

(v) Employee 2010 Bonuses Holdback

This Agreement contemplates that, prior to the Closing, the employees of the Company shall have been paid bonuses awarded at the Company’s discretion to reflect each employee’s contribution to the Company’s success for the 2010 calendar year. In the event that such bonuses have not been paid prior to the Closing, an amount of [***] (the “Employee 2010 Bonuses Holdback”) shall be withheld from the Closing Cash Payment to enable Buyer to make payments in lieu of the Company. In the event that the Employee 2010 Bonuses Holdback exceeds the amount actually paid by Buyer to employees after the Closing, such excess amount shall be paid to the Shareholders Representative (for further distribution to the Sellers) within a commercially reasonable time after payment of employees has been made.

(vi) Georgia Department of Transportation 511 Contract (“GDOT 511 Contract”) Holdback

This Agreement contemplates that, at the Closing, obligations may remain for payment of up to [***] for operating and maintenance costs for the GDOT 511 Contract that ended October 31, 2010 that exceeded income generated from a combination of sponsorships and advertising through October 31, 2010. Therefore, in order to reserve funds for payment after Closing of these obligations incurred prior to the Closing, an amount of [***] (the “GDOT 511 Holdback”) shall be withheld from the Closing Cash Payment to cover the obligations. In the event that the GDOT 511 Holdback exceeds the amount actually paid by Seller to discharge these obligations prior to March 31, 2011, such excess amount shall be paid to the Shareholders Representative (for further distribution to the Sellers, Pro Rata) within a commercially reasonable time after issuance of Buyer SEC Form 10-K for the period ended March 31, 2011.

[***] Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission.

1.2-1

(b) Adjustments to First Deferred Payment.

(i) GDOT Contract

This Agreement contemplates that the operating and maintenance costs for the GDOT 511 Contract will be [***] during the first 12-month period after the Closing and that the Company will conduct this business in the ordinary course consistent with past practices prior to the Closing. It is expected that income generated from a combination of sponsorships and advertising during this same time frame will cover the operating and maintenance costs and provide revenue for GDOT 511 Contract participants. Should the GDOT 511 Contract income sources fail to generate adequate income to cover the lesser of 1) the expected operating and maintenance expenses, or 2) the actual operating and maintenance expenses for the GDOT 511 Contract during this period, the First Deferred Payment shall be reduced by fifty percent (50%) of the amount such operating and maintenance costs exceed the income received and the remaining 50% shortfall in income (the “GDOT 511 Shortfall Amount”) will be carried over to the Second Deferred Payment. Since such amounts will not be known on the 12-month anniversary date of the Closing, an amount of [***] (the “GDOT 511 12-Month Holdback”) shall be withheld from the First Deferred Payment to cover such excess operation and maintenance costs. In the event that 50% of the GDOT 511 Contract excess operating and maintenance costs through the 12-month anniversary date of the Closing are less than the GDOT 511 12-Month Holdback, such amount shall be paid to the Shareholders Representative (for further distribution to the Sellers, Pro Rata) within a commercially reasonable time after issuance of Buyer SEC Form 10-K for the period ended March 31, 2012.

(ii) MDSS First Year License Adjustment

As set forth in that certain Settlement and License Agreement effective as of October 29, 2010 between the Company and Concaten, Inc. and IWAPI, Inc. (“Concaten”), the Company is obligated to pay a license fee (the “Concaten License Fee”) for each road maintenance vehicle equipped with an AVL system used for providing Company’s MDSS services. This Agreement contemplates that the total Concaten License Fee payable to Concaten from the Closing through the end of the 2010 - 2011 season for which MDSS services are provided, will be less than or equal to [***]. The First Year Deferred Payment shall be reduced by the “MDSS First Year License Adjustment”, which shall be the lesser of (A) [***] or (B) the total Concaten License Fee paid to Concaten from Closing through the end of the 2010 – 2011 season less the amount of such fees paid by pass-through of the Concaten License Fee to the Company’s MDSS clients or customers.

2) If, within 12 months after the Closing, a Key Employee terminates his/her employment other than pursuant to a Termination for Good Reason or Buyer terminates a Key Employee’s employment pursuant to a Discharge for Cause, then the amount of the First Deferred Payment will be reduced by the percentage specified for such Key Employee listed below adjusted proportionally to the number of months the Key Employee remained a full time employee during the year. The total percentage reduction cannot exceed 100%.

[***]

(i) GDOT Contract

[***] Confidential treatment has been requested for the bracketed portions. The confidential redacted portion has been omitted and filed separately with the Securities and Exchange Commission.

Same as Section (b)(iii)(1) above.

2) If, within the period from 12 to 24 months after Closing, a Key Employee terminates his/her employment other than pursuant to a Termination for Good Reason or Buyer terminates a Key Employee’s employment pursuant to a Discharge for Cause, then the amount of the Second Deferred Payment will be reduced by the percentage specified for such Key Employee listed below adjusted proportionally to the number of months the Key Employee remained a full time employee during the year. The total percentage reduction cannot exceed 100%.

[***]

(i) Subject to the provisions below, Company shall be eligible to receive the Additional Consideration in accordance with this Schedule 1.2(d).

(ii) As used in this Schedule 1.2(d), the terms set forth below shall have the following meanings:

1.2-4

(iii) Revenue Goals and Operating Income Goals for Year 1 and Year 2 are as set forth in the following table:

	Year 1	Year 2
Revenue Goals	[***]	[***]
Operating Income Goals	[***]	[***]

(iv) The Additional Consideration that may be earned in each of Year 1 and Year 2 is One Million Dollars ($1,000,000) of which [***] in each year is subject to the achievement of that year’s Revenue Goal and [***] in each year is subject to the achievement of that year’s Operating Income Goal. Additional Consideration in each of Year 1 and Year 2 is based upon the actual Revenue and Operating Income during the year determined from audited or reviewed corporate financial records. Additional Consideration Factors for both Revenue (“REV ACF”) and Operating Income (“OI ACF”) are determined from the table below based upon the Goal Achievement percentage. Additional Consideration is then calculated as follows:

Additional Consideration = REV ACF x [***] + OI ACF x [***]

Example: with 96% Revenue Goal Achievement and 105% Operating Income Goal Achievement in Year 1:

Additional Consideration = 68.3%* x [***] + 83%** x [***]= [***].

	Additional Consideration Factor
Goal Achievement	Year 1	Year 2
*Revenue*

100% to 110% of Goal**	75 - 100%	75% - 100%
85% to 100% of Goal*	50% - 75%	50% - 75%
Less than 85% of Goal	0%	0%
Operating Income

(vi) Revenue and Operating Income used in the calculations of Section (d) shall be based upon the actual Revenue and Operating Income during Year 1 or Year 2, as the case may be, resulting from the operation of the Business and determined from audited or reviewed corporate financial records. No later than concurrent with the respective payment for Year 1 or Year 2, as applicable, Buyer will provide to the Shareholder Representative a report in writing certifying as to the amount of Revenue and Operating Income attained in such year from the operation of the Business as defined in this Agreement and as to the calculations of Additional Consideration.

(e) Unless the Shareholder Representative notifies Buyer within 15 days after receipt of the report that it objects to the computations reflected therein, the report shall be binding and conclusive for all purposes of this Schedule 1.2(d). The Shareholder Representative shall have reasonable access to the books and records of Buyer necessary to verify the amount of computations.

(f) If the Shareholder Representative notifies Buyer in writing within 15 days after receipt of Buyer’s report that it objects to the computations set forth therein, the grounds for such objection shall be negotiated in good faith between the Shareholder Representative and Buyer and the corresponding payment shall be adjusted as necessary. If, upon completion of such fifteen (15) day period, Buyer and the Shareholders Representative are unable to reach an agreement, they shall promptly thereafter cause the Independent Accountant to review this Agreement and the disputed items or amounts for the purpose of calculating the Additional Consideration. In making such calculation, the Independent Accountant shall consider only those items or amounts in the Buyer’s financial statements for the applicable period as to which Buyer and the Shareholders Representative have disagreed. The Independent Accountant shall deliver to the Shareholders Representative and Buyer, as promptly as practicable, a report setting forth its calculations. Such report shall be final and binding upon Buyer and Sellers. The cost of such review and report shall be paid (i) one-half by Sellers, Pro Rata, and (ii) one-half by Buyer.
