EARNOUT

8.1           Earnout.  Following the Closing Date, the Shareholders and the Non-Party Shareholders shall be eligible to receive Deferred Cash Consideration and Deferred Stock Consideration (collectively, the “Deferred Consideration”), payable in up to four payments (each an “Earnout Payment” and collectively the “Earnout Payments”) based on the Aggregate First Twelve Calendar Quarters Pre-Tax Earnings.  Such Deferred Consideration, if any, shall be calculated as indicated below based upon the earnings target reached as set forth below:

(a)           If the Aggregate First Twelve Calendar Quarters Pre-Tax Earnings is less than $10,000,000, then no Deferred Consideration shall be payable to the shareholders and no Earnout Payment shall be paid to Shareholders and the Non-Party Shareholders;

(b)           At such time as the Aggregate First Twelve Calendar Quarters Pre-Tax Earnings is equal to at least $10,000,000, then Deferred Consideration in the amount of $2,850,000 shall be payable to the Shareholders and the Non-Party Shareholders and the first Earnout Payment (the “First Earnout Payment”) shall be paid to the Shareholders and the Non-Party Shareholders.  The First Earnout Payment shall be paid as follows:  (i)  $1,350,000 of Deferred Cash Consideration, and (ii) Deferred Stock Consideration of THK Common Stock having an aggregate value of $1,500,000, such stock to be valued at the average closing price per share of THK Common Stock on the last thirty (30) trading days prior to the end of the last calendar quarter prior to such Earnout Payment;

(c)           At such time as the Aggregate First Twelve Calendar Quarters Pre-Tax Earnings is equal to at least $15,000,000, then Deferred Consideration in the amount of $5,700,000 shall be payable to the Shareholders and the Non-Party Shareholders and the second Earnout Payment (the “Second Earnout Payment”) shall be paid to the Shareholders and the Non-Party Shareholders.  The Second Earnout Payment shall be paid as follows:  (i)  $2,700,000 of Deferred Cash Consideration, and (ii) Deferred Stock Consideration of THK Common Stock having an aggregate value of $3,000,000, such stock to be valued at the average closing price per share of THK Common Stock on the last thirty (30) trading days prior to the end of the last calendar quarter prior to such Earnout Payment;

(d)           At such time as the Aggregate First Twelve Calendar Quarters Pre-Tax Earnings is equal to at least $20,000,000, then Deferred Consideration in the amount of $5,700,000 shall be payable to the Shareholders and the Non-Party Shareholders and the third Earnout Payment (the “Third Earnout Payment”) shall be paid to the Shareholders and the Non-Party Shareholders.  The Third Earnout Payment shall be paid as follows:  (i)  $2,700,000 of Deferred Cash Consideration, and (ii) Deferred Stock Consideration of THK Common Stock having an aggregate value of $3,000,000, such stock to be valued at the average closing price per share of THK Common Stock on the last thirty (30) trading days prior to the end of the last calendar quarter prior to such Earnout Payment;

38

(e)           At such time as the Aggregate First Twelve Calendar Quarters Pre-Tax Earnings is equal to at least $25,000,000, then Deferred Consideration in the amount of $5,700,000 shall be payable to the Shareholders and the Non-Party Shareholders and the fourth Earnout Payment (the “Fourth Earnout Payment”) shall be paid to the Shareholders and the Non-Party Shareholders.  The Fourth Earnout Payment shall be paid as follows:  (i)  $2,700,000 of Deferred Cash Consideration, and (ii) Deferred Stock Consideration of THK Common Stock having an aggregate value of $3,000,000, such stock to be valued at the average closing price per share of THK Common Stock on the last thirty (30) trading days prior to the end of the last calendar quarter prior to such Earnout Payment.

(f)            In no event shall the aggregate amount of the Deferred Consideration exceed Nineteen Million Nine Hundred Fifty Thousand Dollars ($19,950,000).  If more than one of clauses (b), (c), (d) and (e) above are satisfied as of the end of the same calendar quarter, the Earnout Payments for each such threshold shall be due and payable at the same time.  If it is determined that the Shareholders and the Non-Party Shareholders are entitled to Deferred Consideration for any completed calendar quarter, THK shall be irrevocably obligated to make the related Earnout Payment, even if the Aggregate First Twelve Calendar Quarters Pre-Tax Earnings for calendar quarters ending after such calendar quarter falls below the applicable threshold triggering such Deferred Consideration for the prior calendar quarter.  In no event shall any shareholder or Non-Party Shareholder be obligated to return, repay, waive or rescind any Deferred Consideration which THK is obligated to pay under any circumstances, including a subsequent decline in the Aggregate First Twelve Calendar Quarter Pre-Tax Earnings below the applicable threshold triggering such Deferred Consideration at the end of any Subsequent Calendar Quarter.

(g)           Notwithstanding any provision to the contrary in this Agreement, THK, in its sole discretion, shall be permitted to pay to the Shareholders and the Non-Party Shareholders any portion of the Deferred Stock Consideration that is required to be paid hereunder in cash in lieu of shares of THK Common Stock to the extent that such portion of the Deferred Stock Consideration would cause the total Stock Consideration to be paid by THK pursuant to this Agreement to exceed 20% of the shares of THK Common Stock issued and outstanding immediately prior to the Effective Time.  THK covenants and agrees that it will seek approval from its shareholders for the issuance of the Deferred Stock Consideration to the extent it does or will exceed 20% of the outstanding shares of THK Common Stock at the next annual or special meeting of its shareholders held after the annual meeting scheduled for March 14, 2006 or any postponements or adjournments thereof.  The rights set forth in the first sentence of this paragraph (g) shall terminate if such shareholder approval is obtained.

8.2           Timing of Earnout Payments.  The Earnout Payments, if required to be delivered by THK to the Shareholders and the Non-Party Shareholders as described above, shall be delivered by THK to the Shareholders and the Non-Party Shareholders within thirty (30) days following the receipt by THK from the THK Accountants of the calculations of the Aggregate First Twelve Calendar Quarters Pre-Tax Earnings for the applicable calendar quarter.  THK will use good faith efforts to cause the THK Accountants to deliver such calculations to THK and each Shareholder as promptly as practicable following the end of each calendar quarter, but in no event later than the date on which THK files its applicable SEC report for such calendar quarter.

39

Subject to Section 2.6, each Earnout Payment shall be delivered to each Shareholder and Non-Party Shareholder who received the Initial Cash Consideration and Initial Stock Consideration in the same proportion as such initial distributions.

8.3           Calculation of Aggregate First Twelve Calendar Quarters Pre-Tax Earnings.  Following the end of each calendar quarter included in the First Twelve Quarters, the THK Accountant shall calculate the Aggregate First Twelve Calendar Quarters Pre-Tax Earning using GAAP consistently applied for each period.  When calculating the Aggregate First Twelve Calendar Quarter Pre-Tax Earnings for any period, any expenses for taxes and amortization of goodwill and other assets arising from the consummation of the transactions contemplated by this Agreement shall not be included.  Any payments made from the Bonus Pool created pursuant to Section 6.5 shall not be included when calculating the First Twelve Quarters Pre-Tax Earnings for any period.  Further, unless THK and the Shareholders mutually agree, no charge against the earnings of Litmus Surviving Company shall be allowed for any expenses of THK in the nature of overhead, management fee or otherwise, when calculating the Aggregate First Twelve Quarter Pre-Tax Earnings for any period, other than (i) expenses incurred by THK but allocated and charged to Litmus Surviving Company and directly related to preparing the financial statements of Litmus Surviving Company and its Subsidiaries or to determining or certifying the Aggregate First Twelve Quarters Pre-Tax Earnings for any period and (ii) expenses or other charges incurred by THK and arising from or related to any claim asserted by or against Litmus Surviving Company.

10.2         Indemnification.

(a)           The Shareholders jointly and severally agree to indemnify and hold harmless THK and Litmus Acquisition Sub, and each of their respective successors and assigns, together with all of their officers and directors (collectively, the “THK Indemnitees”), from and against any and all losses, damages, liabilities, obligations, costs or expenses (any one such item being herein called a “Loss” and all such items being herein collectively called “Losses”), which are caused by or arise out of (1) any material breach or default in the performance by the Shareholders or Litmus of any covenant or agreement of the Shareholders or Litmus contained in this Agreement; (2) any material breach of warranty or materially inaccurate or erroneous representation made by the Shareholders or Litmus herein or in any Schedule delivered to THK or Litmus Acquisition Sub pursuant hereto or in any certificate or other instrument delivered by

45

or on behalf of the Shareholders or Litmus pursuant hereto; and (3) any and all actions, suits, proceedings, claims, demands, judgments, costs and expenses (including reasonable legal fees) arising out of the foregoing.  Without limiting the generality of the immediately preceding sentence, the Shareholders, jointly and severally, shall indemnify and hold harmless the THK Indemnitees from and against Claims of Any Nature regarding Litmus and its Subsidiaries created or incurred prior to the Closing other than Approved Liabilities (“Unapproved Liabilities”) arising and for which notice is given within eighteen (18) months after the Closing Date.  The foregoing notwithstanding, a Shareholder’s obligation with respect to any Loss arising from the material breach in the performance of any agreement or covenant incorporated herein by reference (e.g., pursuant to the Registration Rights Agreement or the applicable Shareholder Employment Agreement) shall be limited to that Shareholder’s breach and shall not extend to a breach by the other Shareholder.  For purposes of this Agreement, any “Losses” or liability for Unapproved Liabilities, shall be limited to those amounts for which the THK Indemnitees do not receive coverage under any applicable insurance policy and shall be net of any tax benefit received by the THK Indemnitees as a result of such Loss.

(b)           THK and Litmus Acquisition Sub jointly and severally agree to indemnify and hold harmless the Shareholders, and their respective successors and assigns, from and against any and all Losses which are caused by or arise out of (1) any material breach or default in the performance by THK or Litmus Acquisition Sub of any covenant or agreement of THK or Litmus Acquisition Sub contained in this Agreement; (2) any material breach of warranty or materially inaccurate or erroneous representation made by THK or Litmus Acquisition Sub herein or in any Schedule delivered to the Shareholders or Litmus pursuant hereto or in any certificate or other instrument delivered by or on behalf of THK or Litmus Acquisition Sub pursuant hereto; and (3) any and all actions, suits, proceedings, claims, demands, judgments, costs and expenses (including reasonable legal fees) arising out of the foregoing.

Notwithstanding the foregoing, if within ten (10) Business Days after delivery of the indemnified party’s notice described above, the indemnifying party indicates in writing to the

indemnified party that, as between such parties, such claims shall be fully indemnified for by the indemnifying party as provided herein, then the indemnifying party shall have the right to control the defense of such claim, provided that the indemnified party shall have the right (1) to participate in the defense thereof and be represented, at his or its own expenses, by advisory counsel selected by it, and (2) to approve any settlement if the indemnified party’s interests are, or would be, affected thereby, which approval shall not be unreasonably withheld, conditioned or delayed.

10.4         Set-Off.  Subject to the limits set forth below, THK shall have the right to set-off the amount of any of THK’s Losses which are indemnifiable by the Shareholders pursuant to this Article X against any Earnout Payment that is or may be due and owing to the Shareholders pursuant to Article VIII of this Agreement (the “Set-Off”).  Any Set-Off shall be in equal parts against the Deferred Cash Consideration and Deferred Stock Consideration.  If THK intends to apply or offset any Earnout Payments prior to the time when the amount of any indemnification which an indemnified party is claiming it is entitled to is determined either by written agreement between the indemnifying party and the indemnified party or by final judgment or decree of a Court of competent jurisdiction, then THK shall deposit the Set-Off amount with the escrow agent under the escrow agreement (the “Set-Off Escrow Agreement”) attached as Exhibit E, to be held and disbursed in accordance with the Set-Off Escrow Agreement.  Any such Set-Off shall be pro rata among the Shareholders based on their existing share ownership of Litmus (not taking into account shares owned by the Non-Party Shareholders).  The Shareholders shall remain liable for the amount of all THK Losses in excess of the Set-Off, if any, as limited below.

47

(d)           Violations or Breaches of Adknowledge Release Agreement.  The Shareholders shall be liable for any Losses suffered or incurred by any THK Indemnitees which are caused by or arise out of any breach or violation of the Adknowledge Release Agreement by Litmus Surviving Company or the Shareholders, including but not limited to any breach of the representations and warranties set forth in Section 4.22 hereof, without regard to the basket or cap set forth in Sections 10.5(a) and 10.5(c); provided, that each Shareholder shall not be liable for violations of the Adknowledge Release Agreement by the other Shareholder.  The Shareholders shall keep THK appraised of any claims or notices received or given by Litmus Surviving Company, the Shareholders, the Non-Party Shareholders or Melissa Linden under or relating to the Adknowledge Release Agreement.  THK shall not be liable or responsible for any losses or damages arising under or resulting from the Adknowledge Release Agreement, including any damages payable under Sections 16-18 of the Adknowledge Release Agreement, other than any losses or damages caused by THK’s own actions.  In addition, THK shall not be liable or responsible for any losses or damages if Linden is not permitted to work for Litmus Surviving Company as a result of the Adknowledge Release Agreement, including loss of any severance payments under the Linden Employment Agreement or termination of the unvested warrants under the applicable Warrant Agreement with Linden in connection with termination of his employment.

ARTICLE XI

TERMINATION

11.1         Termination.

(a)           Litmus and the Shareholders, on the one hand, and THK and Litmus Acquisition Sub, on the other hand, shall have the right to terminate this Agreement in the event that one of the conditions precedent to Closing set forth in Section 9.1 cannot be met (other than as a result of a breach of or failure to perform under this Agreement by the Party seeking to terminate this Agreement).

(b)           This Agreement shall terminate if the Closing does not occur by March 20, 2006, unless such date is extended by mutual agreement of the Parties.

11.2         Effect of Termination.

(a)           In the event of termination of this Agreement as provided in Section 11.1, this Agreement shall forthwith become void and have no effect, without any liability or obligation on the part of any party, except to the extent that such termination results from the willful and material breach by a party of any of its representations, warranties, covenants or other agreements set forth in this Agreement, or as set forth in Section 11.2(b), below.

(b)           If THK, on the one hand, or Litmus and the Shareholders, on the other hand, fail or refuse to close the Merger on the terms contemplated by the Letter of Intent dated December 7, 2005 among Litmus, the Shareholders and THK, and such failure or refusal cannot be justified by (i) in the case of THK, the results of THK’s due diligence investigation of Litmus,

48

(ii) the failure of THK, on the one hand, or Litmus and the Shareholders, on the other hand, to agree upon the Definitive Documents (as defined in the Letter of Intent), or (iii) failure of any of the conditions of closing in Article IX to be satisfied notwithstanding the parties’ commercially reasonable efforts, then and in such event the breaching party shall pay the other party a breakup fee of $100,000 as liquidated damages for such failure or refusal.

ARTICLE XII

TAX MATTERS

12.1         Tax Returns.

(a)           The Shareholders shall prepare and file or cause to be filed when due (taking into account all extensions properly obtained) all Tax Returns that are required to be filed by or with respect to Litmus for taxable years or periods ending on or before the Closing Date, and the Shareholders shall remit or cause to be remitted any Taxes due in respect of such Tax Returns except that, to the extent such Taxes were reflected on the Audited Closing Date Balance Sheet as Liabilities and Litmus satisfied the conditions of closing set forth in Section 9.1(j), such amounts shall be paid by Litmus Surviving Company.  THK shall prepare and file or cause to be filed when due (taking into account all extensions properly obtained) all Tax Returns that are required to be filed by or with respect to Litmus Surviving Company for taxable years or periods ending after the Closing Date and THK shall remit or cause to be remitted any Taxes due in respect of such Tax Returns.

(b)           From and after the Closing, and subject to Section 12.1(a), the Shareholders shall indemnify THK, pursuant to Article X, for all (1) Taxes imposed on Litmus for any taxable year or period, or portion thereof, that ends on or before the Closing Date and (2) Taxes of any Person (other than Litmus) imposed on Litmus as a transferee or successor, by contract or pursuant to any requirement of laws, which Taxes relate to an event or transaction occurring before the Closing Date.  In the case of a Straddle Period, the Taxes of Litmus (or Taxes for which Litmus is liable) for the portion of the period ending on the Closing Date (for which the Shareholders is liable) shall be determined based on an interim closing of the books as of the close of business on the Closing Date (and for such purpose, the taxable period of any partnership or other pass-through entity in which Litmus holds a beneficial interest shall be deemed to terminate at such time), except that the amount of any such Taxes that are imposed on a periodic basis and are not based on or measured by income or receipts shall be determined by reference to the percentage that the number of days in the portion of such period ending on the Closing Date bears to the total number of days in such period beginning after the Closing Date.

(c)           THK shall promptly cause Litmus Surviving Company to prepare and provide to the Shareholders a package of Tax information materials, including, without limitation, schedules and work papers (the “Tax Package”) required by the Shareholders to enable the Shareholders to prepare and file all Tax Returns required to be prepared and filed by the Shareholders pursuant to Section 12.1(a).  The Tax Package shall be completed in accordance with past practice, including past practice as to providing such information and as to the method of computation of separate taxable income or other relevant measure of income of Litmus.  THK

49

and Litmus Surviving Company shall cause the Tax Package to be delivered to the Shareholders within 60 days after the Closing Date.

12.2         Contest Provisions.

(a)           THK shall promptly notify the Shareholders in writing upon receipt by THK, Litmus Surviving Company or any of their respective Affiliates of notice of any pending or threatened federal, state, local or foreign Tax audits, examinations or assessments which might affect the Tax liabilities for which the Shareholders may be liable pursuant to Section 12.1 and Article X.

(b)           The Shareholders shall have the right to represent Litmus’ interests in any Tax audit or administrative or Court proceeding relating to taxable periods ending on or before the Closing Date, and to employ counsel of its choice at its expense; provided, however, that the Shareholders shall have no right to represent Litmus’ interests in any Tax audit or administrative or Court proceeding unless the Shareholders shall have first notified THK in writing of the Shareholders’ intention to do so and shall have agreed with THK in writing that, as between THK and the Shareholders, the Shareholders shall be liable for any Taxes that result from any audit or proceeding.  Litmus Surviving Company and its representatives shall have the right to fully participate at their expense in any audit or proceeding and to consent to any settlement which affects a Tax period or Straddle Period ending after the Closing Date.  THK shall have the sole right to defend Litmus with respect to any issue arising with respect to any Tax audit or administrative or court proceeding relating to taxable periods ending on or before the Closing Date to the extent THK shall have agreed in writing to forego any indemnification under this Agreement with respect to the issue.  Notwithstanding the foregoing, the Shareholders shall not be entitled to settle, either administratively or after the commencement of Litigation, any claim for Taxes which could adversely affect the liability for Taxes of THK, Litmus or any Affiliate thereof for any period after the Closing Date to any extent (including, but not limited to, the imposition of income Tax deficiencies, the reduction of asset basis or cost adjustments, the lengthening of any amortization or depreciation periods, the denial of amortization or depreciation deductions, or the reduction of loss or credit carryforwards) without the prior written consent of THK, which consent may be withheld in the sole discretion of THK unless the Shareholders has indemnified THK in a manner acceptable to THK against the effects of any such settlement.
