(v) The “Cap” for the first Earnout Period shall be $550,000 and for the second, third and fourth Earnout Periods shall be $500,000, except that, to the extent that the Cap for any Earnout Period, other than the fourth, exceeds the Earnout Payments for such Earnout Period, the excess shall be added to the Cap for the next Earnout Period.

(vi) “Acquired Corporation Products” shall mean (A) Acquired Corporation products in existence at Closing or variations developed by Acquired Corporation, (B) Acquired Corporation products generated from the Shell Agreement, (C) partial and full customization of simulators and tutorials that Acquired Corporation may develop during the Earnout Periods for TOTAL-NL, TOTAL-Antwerp, and Hexion Chemicals NL/USA, and (D) products generated from other R&D projects currently in existence. The products included in the current R&D projects are:

▇. ▇▇▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇

▇▇

▇. Gasoline Blending

(III) 3D animation hook up with Acquired Corporation simulation products.

(vii) “Acquired Corporation Services” shall mean any services utilizing Acquired Corporation Products and services to be provided under the terms of any maintenance agreements for Acquired Corporation Products.

The first Earnout Payment with respect to each Earnout Period shall be made one month after the end of the Earnout Period and will be equal to 50% of the amount, if any, by which the amount of cash collected during the Earnout Period with respect to the Revenues for such Earnout Period exceeds the Threshold for such Earnout Period, the second Earnout Payment with respect to each Earnout Period shall be made seven months after the end of the Earnout Period and will be equal to (A) 50% of the amount, if any, by which the amount of cash collected during the Earnout Period and the succeeding six months with respect to the Revenues for such Earnout Period exceeds the Threshold for such Earnout Period less (B) the first Earnout Payment for such Earnout Period, and the third Earnout Payment with respect to each Earnout Period shall be made thirteen months after the end of the Earnout Period and will be equal to (A) 50% of the amount, if any, by which the amount of cash collected during the Earnout Period and the succeeding 12 months with respect to the Revenues for such Earnout Period exceeds the Threshold for such Earnout Period less (B) the first Earnout Payment for such Earnout Period and the second Earnout Payment for such Earnout Period; provided that in no event shall the sum of the Earnout Payments for any Earnout Period exceed the Cap for such Earnout Period. For example, if the Revenues for the first Earnout Period equal $2.5 million and $2 million of cash is collected during such Earnout Period with respect to such Revenues, $2.3 million is collected during such Earnout Period and the succeeding six months with respect to such Revenues, and $2.4 million is collected during such Earnout Period and the succeeding 12 months with respect to such Revenues, the Representative would be entitled to receive a first Earnout Payment with respect to the first Earnout Period of $300,000, a second Earnout Payment with respect to the first Earnout Period of $150,000, and a third Earnout Payment with respect to the first Earnout Period of $50,000. Since the total of the Earnout Payments received with respect to the first Earnout Period is $500,000, $50,000 less than the Cap for that period, the Cap for the second Earnout Period would be increased from $500,000 to $550,000.

(d) Within 90 days of the Closing, the Purchaser will prepare a consolidated balance sheet (the “Closing Date Balance Sheet”) of the Acquired Corporation and the Indian Subsidiary as of the Closing Date. The Closing Date Balance Sheet will be prepared in accordance with generally accepted accounting principles.

With respect to the assets and liabilities on the Closing Date Balance Sheet, the Stockholders and the Purchaser agree as follows:

(i) The Representative will be entitled to receive all the cash in the Acquired Corporation and the Indian Subsidiary except for (a) $400,000, which will be retained by the Acquired Corporation as working capital, and (b) an amount of cash equal to the maintenance payments which have been received by Acquired Corporation prior to Closing but which relate to revenues to be earned after the Closing, which will be retained by the Acquired Corporation. Such cash will be paid to the Representative promptly after the Closing Date Balance Sheet is prepared. The Stockholders will be credited on the Closing Date Balance Sheet as cash for any pre-paid expenses paid in the ordinary course of its business relating to periods after the Closing Date. Any liabilities contained on the Closing Date Balance Sheet will be the responsibility of the Stockholders.

(ii) Except as set forth below, the Representative will be entitled to receive an amount equal to 70% of the cash collected prior to March 31, 2013 from the receivables and earned but unbilled amounts which appear on the Closing Date Balance Sheet and the remaining 30% will be retained by the Acquired Corporation. If the actual costs (the “Shell Actual Costs”) to complete any of the Shell Projects represented on the Closing Date Balance Sheet are more than 110% of the estimated costs (the “Shell Estimated Costs”) to complete such Shell Project, the payment for the earned but unbilled revenue (the “Shell Project Revenue”) on the Closing Date Balance Sheet with respect to such Shell Project shall be reduced by an amount equal to the difference between (a) an amount equal to what the Shell Project Revenue would have been if the Shell Estimated Costs with respect to such Shell Project were increased by 10% and (b) an amount equal to what the Shell Project Revenue would have been based upon the Shell Actual Costs with respect to such Shell Project. Provided further, however, that to the extent that the Shell Actual Costs are less the Shell Estimated Costs with respect to any Shell Project, the Representative will be provided with a credit which can be used against any reduction described above on another Shell Project to lessen such reduction. The Acquired Corporation will be entitled to retain 100% of the cash collected with respect to receivables which appear on the Closing Date Balance Sheet to the extent such receivables relate to revenue to be earned after the Closing under maintenance agreements. The Representative will receive three payments for receivables and earned but unbilled amounts: the first will be made within 10 days of March 31, 2011 based on cash collections during the period from the Closing Date through March 31, 2011, the second will be made within 10 days of March 31, 2012 based on cash collections during the period from April 1, 2011 through March 31, 2012 and the third will be made within 10 days of March 31, 2013 based on cash collections during the period from April 1, 2012 through March 31, 2013.

(a) any breach of any representation or warranty of Acquired Corporation or any Stockholder contained in this Agreement, provided, however, that no indemnification shall be payable by Stockholders with respect to any claim for Losses arising out of, based upon, or in connection with the breach of any representation or warranty made by Stockholders: (i) asserted by Purchaser after the expiration or termination date, if any, prescribed for such representation or warranty in Section 5.04; (ii) except with respect to breaches of the representations and warranties in (a) Section 1.04 related to liabilities on the Closing Date Balance Sheet, asserted within 120 days of the Closing, (b) Section 1.04, relating to taxes, and (c) Section 1.12, until the total of such otherwise recoverable claims for indemnification shall exceed $40,000, at which time Purchaser shall be entitled to recover the amount of all such claims in excess of such amount; and (iii) in an aggregate amount (x) in excess of the sum of the amounts delivered by Purchaser to the Representative pursuant to Sections 3.01(b)(i), (ii), (iii), and with respect to the receivables and earned but unbilled amounts which appear on the Closing Date Balance Sheet; (y) minus $600,000.

In the event that the Earnout Payments payable to the Representative under Section 3.01(b)(iii),the amounts payable to the Representative with respect to the Shell Payments under Section 3.01(b)(ii), and the amounts payable to the Representative with respect to the receivables and earned but unbilled amounts which appear on the Closing Date Balance Sheet are not sufficient to satisfy the indemnification obligations of Section 3.03 indemnification may be sought against up to $600,000 of the $1.2 million payment made under Section 3.01(b)(i). The obligations of the Stockholders to indemnify the Purchaser for claims related to the Closing Date Balance Sheet and asserted within 120 days of the Closing Date or Section 1.04 related to taxes in an amount equal to the aggregate losses, liabilities, claims, damages, and expenses whatsoever incurred or demonstrably in prospect of being incurred by any Indemnitee with respect to which such Indemnitee is entitled to be indemnified pursuant to Section 3.03, may be satisfied by (i) from the Earnout Payments payable to the Representative under Section 3.01(b)(iii), (ii) from any amounts payable to the Representative with respect to the Shell Payments under Section 3.01(b)(ii), (iii) from any amounts payable to the Representative with respect to the receivables and earned but unbilled amounts which appear on the Closing Date Balance Sheet, and (iv) from up to $600,000 of the $1.2 million payment made under Section 3.01(b)(i).

§4.02 Officers’ and Directors’ Confidentiality Agreement

The Purchaser shall receive at the Closing from each person who is, or who at any time between that date which is one year prior to the date of this Agreement and the date of this Agreement was, an officer or a director of Acquired Corporation or the Indian Subsidiary an agreement to keep confidential certain data, substantially in the form of Exhibit G.

§4.04 Release by Stockholders

Each Stockholder fully and unconditionally releases and discharges all claims and causes of action which he or his heirs, personal representatives, or assigns ever had, now have, or hereafter may have against the Purchaser, Acquired Corporation, or the Indian Subsidiary, or, when acting as such, their respective officers, directors, employees, counsel, agents, and stockholders, in each case past, present, or as they may exist at any time after the date of this Agreement, except claims and causes of action arising out of, based upon, or in connection with this Agreement or any other agreement executed on the date hereof.

§4.05 Noncompetition

Each Stockholder agrees, in consideration of the obligations of the Purchaser hereunder: (a) for a period of five years after the Closing Date, he will not compete with or be engaged in the same business as, or Participate In (as hereinafter defined in this Section 4.05) any other business or organization which at any time during the five-year period after the Closing Date competes with or is engaged in the same business as, Acquired Corporation or the Indian Subsidiary, with respect to any product or service sold or activity engaged in up to the time of the Closing in any geographical area in which at the time of the Closing such product or service is sold or activity engaged in; (b) he will not directly or indirectly reveal the name of, solicit or interfere with, or endeavor to entice away from Acquired Corporation, the Indian Subsidiary, or the Purchaser, any of their respective suppliers, customers, or employees; and (c) he will not directly or indirectly employ any person who, at any time up to the Closing Date, was an employee of Acquired Corporation, the Indian Subsidiary, or the Purchaser, within a period of two years after such person leaves the employ of such corporation.

V. Miscellaneous

§5.01 Brokerage Fees

If, however, it is ultimately determined in any such suit, action, or proceeding (in which the Purchaser and all Indemnitees made a defendant therein or a party thereto were afforded the opportunity to have their counsel participate in the defense) that the Purchaser or any Indemnitee (other than Acquired Corporation or the Indian Subsidiary) made a defendant therein or a party thereto was the sole employer of such broker or finder or services were performed solely for the Purchaser or any Indemnitee (other than Acquired Corporation or the Indian Subsidiary) made a defendant therein or a party thereto, then Stockholders shall not be responsible under this Section 5.01 and amounts theretofore paid by them by reason of this Section 5.01 shall be reimbursed by the Purchaser or the Indemnitee, as the case may be, who was the sole employer.

§5.02 Further Actions

At any time and from time to time, each party agrees, at its or his expense, to take such actions and to execute and deliver such documents as may be reasonably necessary to effectuate the purposes of this Agreement.

§5.03 Availability of Equitable Remedies

Since a breach of the provisions of this Agreement could not adequately be compensated by money damages, any party shall be entitled, either before or after the Closing, in addition to any other right or remedy available to it, to an injunction restraining such breach or a threatened breach and to specific performance of any such provision of this Agreement, and in either case no bond or other security shall be required in connection therewith, and the parties hereby consent to the issuance of such an injunction and to the ordering of specific performance.

§5.04 Survival

The covenants, agreements, representations, and warranties contained in or made pursuant to this Agreement shall survive the Closing and any delivery of the purchase price by the Purchaser, irrespective of any investigation made by or on behalf of any party; provided, however, that (a) the representations and warranties of Stockholders in Article I shall expire and terminate on June 30, 2012, except that those made in Sections 1.01, 1.02, 1.11 and 1.12 shall survive indefinitely, and those made in that portion of Section 1.04 relating to Taxes and to Section 1.08 shall survive until the expiration of the statute of limitations applicable thereto, notwithstanding any investigation by any party, and (b) the representations and warranties of the Purchaser in Article II shall survive indefinitely. The statements contained in any certificate executed by Acquired Corporation, the Indian Subsidiary, any officer of director of the Acquired Corporation or the Indian Subsidiary, or any Stockholder delivered to the Purchaser in connection with the transactions contemplated hereby shall be deemed representations and warranties, covenants and agreements, as the case may be, of Stockholders hereunder for all purposes of this Agreement.

§5.05 Appointment of Agent

▇▇▇▇▇▇▇ ▇▇▇▇▇ will be the representative (the “Representative”) of the interests of Stockholders for all purposes of this Agreement.

Purchaser agrees to make any payment required under this Agreement according to the directions of the Representative in such amounts as may be determined by the Representative and to make any required reporting to US tax authorities and make all required US tax withholdings in connection with such payments.

Any notice given by other means permitted by this Section 5.07 shall be deemed given at the time of receipt thereof.

§5.08 Waiver

Any waiver by any party of a breach of any term of this Agreement shall not operate as or be construed to be a waiver of any other breach of that term or of any breach of any other term of this Agreement. The failure of a party to insist upon strict adherence to any term of this Agreement on one or more occasions will not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement. Any waiver must be in writing and, in the case of a corporate party, be authorized by a resolution of the Board of Directors or by an officer of the waiving party.

§5.09 Joint and Several Obligations

The representations, warranties, covenants, and agreements of Stockholders in this Agreement are joint and several, but no Stockholder shall have any rights against Acquired Corporation or the Indian Subsidiary if a remedy is sought or obtained against any Stockholder because both Acquired Corporation or the Indian Subsidiary and one or more Stockholders breach a representation, warranty, covenant, or agreement.

§5.10 Binding Effect

The provisions of this Agreement shall be binding upon and inure to the benefit of Acquired Corporation and the Purchaser and their respective successors and assigns and each Stockholder and his assigns, heirs, and personal representatives, and shall inure to the benefit of each Indemnitee and its successors and assigns (if not a natural person) and his assigns, heirs, and personal representatives (if a natural person).

§5.13 Headings

The headings in this Agreement are solely for convenience of reference and shall be given no effect in the construction or interpretation of this Agreement.

§5.14 Counterparts; Governing Law

This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. It shall be governed by and construed in accordance with the laws of Delaware, without giving effect to conflict of laws. Any action, suit, or proceeding arising out of, based on, or in connection with this Agreement or the transactions contemplated hereby may be brought only in the United States District Court for the District of Delaware and each party covenants and agrees not to assert, by way of motion, as a defense, or otherwise, in any such action, suit, or proceeding, any claim that it or he is not subject personally to the jurisdiction of such court, that its or his property is exempt or immune from attachment or execution, that the action, suit, or proceeding is brought in an inconvenient forum, that the venue of the action, suit, or proceeding is improper, or that this Agreement or the subject matter hereof may not be enforced in or by such court. Both parties agree to waive any right to a jury for any proceeding resolving a dispute under this Agreement.

IN WITNESS WHEREOF, the parties have duly executed this Agreement as of the date first written above.
