1.5 Purchase Price. In consideration of the rights, interests, assets, and properties transferred to Buyer as set forth in Section 1.1, Buyer shall pay to the Seller the aggregate consideration of Two Million Dollars ($2,000,000) (the “Purchase Price”). Upon execution of the Escrow Agreement, the Buyer shall deposit the Purchase Price with the Escrow Agent in cash or immediately available funds by wire transfer or other means of payment acceptable to the Seller, and the Seller shall deposit with the Escrow Agent the Sale Shares and all documents pertaining to the Sale Shares, including but not limited to original share certificates and other instruments representing the Sale Shares, along with the relevant transfer instruments duly executed by the Seller, to be held and distributed pursuant to the terms of the Escrow Agreement. Pursuant to the Escrow Agreement, at the Closing the Purchase Price shall be payable as follows:

(a) Seller agrees to forgive certain other current liabilities of Sento EU as mutually agreed upon at Closing by the Parties in the minimum amount necessary to cause Sento EU to have Eight Hundred Thousand Dollars ($800,000) in Net Asset Value at Closing. At Closing, the Net Purchase Price shall be released by the Escrow Agent to the account designated by the Seller.

(b) At least three (3) days prior to the Closing Date, Seller shall deliver to Buyer a statement (the “Estimated Closing Statement”) setting forth its good faith written estimate of the Net Purchase Price on the Closing Date determined in accordance with GAAP applied on a basis consistent with the application of such principles in the preparation of the Balance Sheet. The Estimated Closing Statement shall be subject to Buyer’s acceptance as to form and absence of manifest error. An Estimated Closing Statement based on the Sento EU financial statements at November 30, 2007 is included in the Disclosure Schedules as part of Exhibit C and the parties agree that the approach and amounts contained therein are an accurate reflection of the Net Purchase Price and other amounts that would be distributed to Seller if such were to be done

based on the November 30, 2007 numbers. The Estimated Closing Statement referenced in the first sentence of this paragraph shall utilize the same format and shall update the numbers based on the Closing Date estimates as set forth above.

(c) On the Closing Date, the Seller and the Buyer shall be obliged to issue the First Release Notice (as that term is defined in the Escrow Agreement) to the Escrow Agent. Immediately, upon receipt of the First Release Notice, the Escrow Agent shall transfer the Net Purchase Price to the account designated by Seller and release the Sale Shares to the Buyer.

(f) Buyer shall notify Seller in writing within fifteen (15) days of Buyer’s receipt of the Final Closing Statement that it accepts the Final Closing Statement or that there is a dispute as to an item(s) reflected thereon. Such notice will set forth Buyer’s objections, if any, to the Final Closing Statement in reasonable detail. The failure by Buyer to give Seller such notice within such period shall be deemed to constitute Buyer’s acceptance of the Final Closing Statement. The Parties will use all reasonable efforts to resolve any such dispute, but if such dispute cannot be resolved by the Parties within thirty (30) days after Buyer gives notice of such dispute, it shall be referred to the Salt Lake City, Utah office of Deloitte LLP (the “Selected Accountants”). The determination of the Selected Accountants shall be conclusive and binding on each party. The fees of the Selected Accountants shall be borne by the non-prevailing party.

(g) Once both Parties agree to the accuracy of the Final Closing Statement or the determination of the Selected Accountant is received if a dispute exists, the Seller and the Buyer shall be obliged to issue the Second Release Notice (as that term is defined under the Escrow Agreement) to the Escrow Agent and immediately on receipt of such Second Release Notice, the excess or shortage of Net Purchase Price detailed in the Final Closing Statement shall be paid to either the Seller or Buyer as designated in the Final Closing Statement within three (3) Business Days by the Escrow Agent.

(h) Upon receipt by the Buyer of the release/discharge letter referred to in Section 5.13(j) from the Seller, the Seller and the Buyer shall be obliged to issue the Third Release Notice (as that term is defined under the Escrow Agreement) to the Escrow Agent and immediately on receipt of such Third Release Notice, the Escrow Agent shall release Two Hundred Thousand Dollars ($200,000) to the account designated by the Seller. However, if the release/discharge letter referred to in Section 5.13(j) is not received by the Buyer within one hundred eighty (180) days from the Closing Date, the aforesaid Two Hundred Thousand Dollars ($200,000) shall be released by the Escrow Agent to the Buyer.

(i) The Buyer’s sole and exclusive remedy for any adjustment otherwise payable to it under this Section 1.5 shall be offsets to the Purchase Price as calculated in the Final Closing Statement.

place as the Seller and the Buyer may mutually agree (the “Closing Date”). The Closing shall be effective at 11:59 p.m., Mountain Time, on the Closing Date.

1.7 In consideration of the Purchase Price and other good and valuable consideration, the sufficiency of which is hereby acknowledged, effective upon the Closing, the Seller, for itself and its heirs, executors, administrators, successors and assigns, hereby fully, unconditionally and knowingly releases and forever discharges and holds harmless Sento EU and its employees, officers, directors, successors and assigns from any and all claims, demands, losses, costs, expenses (including reasonable attorneys’ fees and expenses), obligations, liabilities and/or damages of every kind and nature whatsoever, whether now existing or known, arising out of the operation or conduct of the Sento EU’s business or a transaction or circumstance occurring or existing or related to the period of time prior to the Closing, relating in any way, directly or indirectly, to Sento EU, this Agreement or the transactions contemplated hereby, that the Seller may now have or may hereafter claim to have against Sento EU or any of such employees, officers, directors, successors or assigns.

Indemnification

8.1	Indemnification.

(a) The Seller, on the one hand, and the Buyer, on the other, shall indemnify and hold harmless the other, and their respective officers, directors, shareholders, parent company, representatives and agents, from all losses, claims, damages, liabilities, obligations, fines,

penalties, judgments, settlements, costs, Expenses, and disbursements (collectively, “Indemnitee Losses”) arising or resulting from (i) any inaccuracy in or breach of any representation or warranty of such party set forth in this Agreement (including the Disclosure Schedules) or any other agreement, instrument or document delivered in connection herewith, or (ii) any breach by such party of a covenant or obligation of such party in this Agreement (including the Disclosure Schedules) or any other agreement, instrument or document delivered in connection herewith. Without limiting the foregoing, (x) the Seller agrees to and does hereby indemnify and hold the Buyer harmless from all Indemnitee Losses resulting or arising from any liabilities or obligations of the Seller not expressly assumed by Buyer hereunder (whether accrued, absolute, fixed, contingent, liquidated or unliquidated, and whether due or to become due), and also arising from any government authority or courts trying to set aside any part of this Agreement; and (y) the Buyer agrees to and does hereby indemnify and hold the Seller harmless from all Indemnitee Losses resulting or arising from any liabilities or obligations of the Seller expressly assumed by Buyer hereunder. Notwithstanding the foregoing, in no event shall the Purchase Price be specifically set aside for purposes of the payment of any Indemnitee Losses of the Buyer except that, the Buyer reserves the right, exercisable at its reasonably applied sole discretion to deduct the amount necessary to make good the Indemnitee Losses suffered by the Buyer from the Retention Amount. “Expenses” shall include all reasonable out-of-pocket attorneys’ fees, retainers, court costs, transcript costs, fees of experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees, and all other out-of-pocket disbursements or expenses of the types customarily incurred in connection with prosecuting, defending, preparing to prosecute or defend, investigating, participating, or being or preparing to be a witness in a Proceeding. The cumulative aggregate indemnification obligation of Seller, on the one hand, and the Buyer, on the other hand, hereunder shall not exceed the Purchase Price. Further, no claim for indemnity shall be made unless and until the aggregate amount of all claims hereunder shall have reached $50,000 and when so reached the claim shall commence from the first dollar, provided that every individual claim of $1,000 or less shall be ignored altogether and shall not be liable to any indemnifications.

(b)

The Seller agrees that in the event of the Buyer making a claim against the Seller, the Seller shall not pursue any claim, seek damages, reimbursements or contribution from Sento EU in respect of such claim. The Seller shall indemnify Buyer from all claims related to the future earnings of Sento EU by the owners/ shareholders of XtraTime, Inc. (the former owners of Sento EU).

(c) Whenever any claim shall arise for indemnification hereunder, the party seeking indemnification (the “Indemnified Party”) shall promptly notify the party from whom indemnification is sought (the “Indemnifying Party”) of the claim and, when known, the facts constituting the basis for such claim. In the event of any such claim for indemnification hereunder resulting from or in connection with any claim or Proceedings by a third party, the notice to the Indemnifying Party shall specify, if known, the amount or an estimate of the amount of the liability arising therefrom. The failure to promptly provide such notice (so long as such notice is provided prior to the expiration of any applicable period specified in Section 10.3) shall not release the Indemnifying Party from any of its obligations under this Section 8 except to the extent the Indemnifying Party is prejudiced by such failure. The Indemnified Party shall not settle or compromise any claim or Proceeding by a third party for which it may be entitled to indemnification hereunder (“Third-Party Claim”) without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld.

(d) In connection with any Third-Party Claim, the Indemnifying Party, at its sole cost and expense, upon written notice to the Indemnified Party, may assume the defense of any such

claim or Proceeding. The Indemnified Party shall be entitled to participate in (but not control) the defense of any such Proceeding, with its counsel and at its own expense. If the Indemnifying Party does not assume the defense of any such claim or Proceeding resulting therefrom within 30 days after the date of such claim or Proceeding, (a) the Indemnified Party may defend against such claim or Proceeding, in such manner as it may deem appropriate, including settling such claim or Proceeding, after giving notice of the same to the Indemnifying Party, on such terms as the Indemnified Party may deem appropriate, and (b) the Indemnifying Party shall be entitled to participate (but not control) the defense of such action, with its counsel and at its own expense. If the Indemnifying Party thereafter seeks to question the manner in which the Indemnified Party defended such third-party claim or Proceeding or the amount or nature of any such settlement, the Indemnifying Party shall have the burden to prove by a preponderance of the evidence that the Indemnified Party did not defend or settle such third-party claim or Proceeding in a reasonably prudent manner.

8.2 Reduction for Insurance Proceeds; Mitigation. If the Buyer actually receives any insurance proceeds following an indemnification payment by the Seller and the proceeds relate to the same events for which such indemnification payment was made, the Buyer shall return the indemnification payments to the Seller, up to the actual amount of insurance proceeds received in respect of such same events, net of any federal and state income tax effects to the Buyer. Each of the parties agrees to take all reasonable steps to mitigate their respective Indemnified Losses upon and after becoming aware of any event or condition which would reasonably be expected to give rise to any Indemnified Losses that are subject to indemnification hereunder.

Section 9

Choice of Law; Jurisdiction; Dispute Resolution

Consent to Jurisdiction.

(a) Subject to the arbitration provisions of Section 9.5 below, each of the Parties hereto hereby consents to the nonexclusive jurisdiction of all state and federal courts located in Sacramento, California, as well as to the jurisdiction of all courts to which an appeal may be taken from such courts, for the purpose of any Proceeding arising out of, or in connection with, this Agreement or any of the related agreements or any of the transactions contemplated hereby or thereby, including any Proceeding relating to ancillary measures in aid of arbitration, provisional remedies and interim relief, or any Proceeding to enforce any arbitral decision or award.

(b) Each Party covenants that it shall not challenge or set aside any decision, award, or judgment obtained in accordance with the provisions hereof.

(c) Each of the Parties hereto hereby expressly waives any and all objections it may have to venue, including the inconvenience of such forum, in any of such courts.

9.3 Waiver of Jury Trial. WITHOUT LIMITING THE PROVISIONS OF SECTION 9.5 RELATING TO ARBITRATION, EACH OF THE PARTIES HERETO HEREBY VOLUNTARILY AND IRREVOCABLY WAIVES TRIAL BY JURY IN ANY PROCEEDING BROUGHT IN CONNECTION WITH THIS AGREEMENT, ANY OF THE RELATED AGREEMENTS AND DOCUMENTS, OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

9.4 Equitable Remedies. The Parties hereto agree that irreparable harm would occur in the event that any of the agreements and provisions of this Agreement were not performed fully by the Parties hereto in accordance with their specific terms or conditions or were otherwise breached, and that money damages are an inadequate remedy for breach of this Agreement because of the difficulty of ascertaining and quantifying the amount of damage that will be suffered by the Parties hereto in the event that this Agreement is not performed in accordance with its terms or conditions or is otherwise breached. It is accordingly hereby agreed that the Parties hereto shall be entitled to an injunction or injunctions to restrain, enjoin, and prevent breaches of this Agreement by the other Parties and to enforce specifically such terms and provisions of this Agreement, such remedy being in addition to and not in lieu of, any other rights and remedies to which the other Parties are entitled to at law or in equity.

Immediately following notice by one party to the other of the existence of a Covered Dispute, the Parties shall attempt in good faith to settle the Covered Dispute. In the event the Covered Dispute is not settled within 15 calendar days after the notice of the existence of the Covered Dispute, the Parties shall submit the Covered Dispute to binding arbitration.

(a) All Proceedings pursuant to this Section 9.5 shall be conducted in accordance with the laws of California, as modified by the terms of this section.

(b) All arbitrators selected shall either (i) be retired senior judges that have served for more than 10 years in the court of record of general jurisdiction in the state whose laws are applicable to the interpretation and enforcement of this Agreement as provided in Section 9.1, or (ii) otherwise be independent licensed attorneys. In the event of the failure, refusal, or inability of any arbitrator to act, a new arbitrator shall be appointed in his or her stead. Such appointment shall be made in the same manner as provided for the appointment of such arbitrator so failing, refusing, or being unable to act.

(c) All matters to be decided in connection with a Covered Dispute shall be resolved by a single arbitrator as provided in this subsection. The party(ies) demanding arbitration shall serve on all other parties, in the manner provided in this Agreement for giving notices, a written demand for arbitration, stating the specific facts upon which arbitration is demanded. Within 15 days after service of the demand for arbitration, the party(ies) upon whom the demand is made shall serve the demanding party(ies) a list of five potential arbitrators. Within 10 days after service of the list of potential arbitrators, the party(ies) demanding arbitration shall select an arbitrator and two alternate arbitrators. Within 10 days after the party(ies) demanding arbitration has selected an arbitrator and two alternates, the parties to the arbitration, by joint communication, shall contact the selected arbitrator to determine if he or she is willing, able, and available to act as arbitrator. If the selected arbitrator, for any reason, is unwilling, unable, or unavailable to act, then the parties, again by joint communication, shall contact the first and, if necessary, the second alternate to determine of he or she is willing, able, and available to act as

arbitrator. If none of the three chosen individuals is willing, able, or available to act as arbitrator, then either party may seek court appointment of an arbitrator pursuant to the laws of California.

(d) The arbitration hearing shall be held no later than 120 days after the appointment of the arbitrator, unless extended by the mutual agreement of all parties to the arbitration. The rules of evidence shall be observed at the arbitration Proceeding. At the discretion of the arbitrator, the arbitrator may require pre-hearing briefs from the parties. Resolution of the Covered Dispute shall be based solely upon the laws governing the claims and defenses pleaded, and the arbitrator may not invoke any basis, including notions of “just cause,” other than such controlling law. As reasonably required to allow full use and benefits of this Agreement, the arbitrator may extend the time set for the giving of notices and setting of hearings.

(e) The fees, costs, and expenses of the arbitration shall be paid one-half by the party(ies) demanding arbitration and one-half by the other party(ies) to the arbitration, subject to an award of reimbursement of fees, costs, and expenses by the arbitrator(s) to the prevailing party(ies).

(f) Arbitration shall be the sole and exclusive remedy between the Parties respecting any Covered Dispute, provided, however, the arbitrator shall not have the power or authority to revoke, reform, or revise any portion of this Agreement or to award consequential, incidental, or punitive damages. Awards shall include the arbitrator’s written, reasoned opinion and, at either party’s written request within 10 days after issuance of the award, shall be subject to reversal and remand, modification, or reduction following a review by the arbitrator of the records and arguments of the parties.

(g) Unless all the parties to an arbitration otherwise consent in writing, the location of the arbitration hearings and the place of entry of the award shall be in Sacramento, California. The arbitration award shall be final and binding and shall not be reviewable in any court on any grounds except corruption, fraud, or undue means of a party or for demonstrable partiality or corruption of the arbitrator. The parties intend to eliminate all other court review of the award and the arbitration Proceedings. Except for Proceedings to enforce or confirm an award, Proceedings for interim, provisional, or injunctive relief as provided herein, or a Proceeding brought by all parties to the Covered Dispute to vacate or modify an award, the initiation of any Proceeding relating to a Covered Dispute that is arbitrable under this Agreement shall constitute a material breach of this Agreement.

(h) The rights, duties, and obligations of the parties under this Section 9.5 shall survive the termination of this Agreement. Termination of this Agreement shall be without prejudice to any rights that have accrued to any party under this Section 9.5.

(i) Except as necessary in a judicial Proceeding allowable under this Section 9.5, all matters relating to any arbitration shall be confidential, including the existence and subject of the arbitration.
