(c) The Closing Statement shall become final and binding upon the parties hereto at 5:00 p.m. Central Time on the sixtieth (60th) day following the date on which the Closing Statement was delivered to the Sellers' Representative (the "Disagreement Deadline") unless the Sellers' Representative delivers written notice of its disagreement with the Closing Statement (a "Notice of Disagreement") to the Buyer prior to such Disagreement Deadline. Any Notice of Disagreement shall specify in reasonable detail (i) the nature of any disagreement so asserted, (ii) each item subject to such disagreement (each, a "Disputed Item"), (iii) the Sellers' Representative's alternative calculations for each such Disputed Item, and (iv) supporting documentation therefor. If a Notice of Disagreement is not received by the Buyer by the Disagreement Deadline, then the Closing Statement (as prepared by the Buyer) shall be final and binding upon the Sellers and the Buyer. If a Notice of Disagreement is received by the Buyer by the Disagreement Deadline, then (A) the portions of the Closing Statement not subject to a Notice of Disagreement and not constituting Disputed Items shall be final and binding on the Buyer and the Sellers, and (B) the portions of the Closing Statement that are the subject of a Notice of Disagreement and constitute Disputed Items (as revised in accordance with this sentence) shall become final and binding upon the Sellers and the Buyer on the earlier of (x) the date the Sellers' Representative and the Buyer resolve in writing any differences they have with respect to the Disputed Items and (y) the date any Disputed Items are finally resolved in writing by the Accounting Firm. During the thirty (30) day period following the delivery of a Notice of Disagreement, the Sellers' Representative and the Buyer shall seek in good faith to resolve in writing any differences that they may have with respect to the Disputed Items specified in the Notice of Disagreement. If at the end of such thirty (30) day period the Sellers' Representative and the Buyer have not resolved in writing the Disputed Items specified in the Notice of Disagreement, the Sellers' Representative and the Buyer shall submit to the Accounting Firm only Disputed Items that remain in dispute from the Notice of Disagreement ("Remaining Disputed Items"). The Sellers' Representative and the Buyer shall use reasonable efforts to cause the Accounting Firm to render a written decision resolving the Remaining Disputed Items submitted to the Accounting Firm within thirty (30) days of the receipt of such submission, including by executing such engagement letters and conflict waivers as may be reasonably required by the Accounting Firm. The scope of the disputes to be resolved by the Accounting Firm shall be limited to fixing mathematical errors and determining whether the Remaining Disputed Items were determined in accordance with the Balance Sheet Rules, to the extent applicable, and the terms of this Agreement, and no other matters. The Accounting Firm's decision shall include the basis for its resolution of the Remaining Disputed Items and be (1) based solely on written submissions by the Sellers' Representative and the Buyer and their respective Representatives (and it shall not permit or authorize discovery or other ex parte

The Accounting Firm may not assign a value greater than the greatest value for any such Remaining Disputed Item claimed by either party or smaller than the smallest value for any such Remaining Disputed Item claimed by either party in the Closing Statement and Notice of Disagreement, respectively. In acting under this Agreement, the Accounting Firm shall function solely as an expert and not as an arbitrator; provided, however, that the Accounting Firm shall have the power to conclusively resolve differences in disputed items as specified in this Agreement. (d) The fees and expenses of the Accounting Firm incurred pursuant to this Section 2.3 shall be borne pro rata as between the Sellers, on the one hand, and the Buyer, on the other hand, in proportion to the final allocation made by such Accounting Firm of the Disputed Items weighted in relation to the claims made by the Sellers' Representative and the Buyer, such that the prevailing party pays the lesser proportion of such fees, costs and expenses. By way of illustration, if the Buyer's calculation would have resulted in a $1,000,000 net payment to the Buyer, the Sellers' Representative's calculation would have resulted in a $1,000,000 net payment to the Sellers and the Accounting Firm's final determination results in an aggregate net payment with respect to the Disputed Items of $500,000 to the Buyer, then the fees and expenses of the Accounting Firm shall be split as follows: the Sellers' Representative (on behalf of the Sellers) shall be responsible for 75% and the Buyer shall be responsible for 25%. By way of further illustration, if the accounting Firm's final determination results in an aggregate net payment with respect to the Disputed Items of $1,000,000 to the Buyer, then the Sellers' Representative (on behalf of the Sellers) shall be responsible for one hundred percent 100% of the fees and expenses of the Accounting Firm. The fees and disbursements of the Representatives of each of the Sellers' Representative and the Buyer incurred pursuant to this Section 2.3 shall be borne by such Party. (e) Within five (5) Business Days after the final determination of the Final Closing Cash, the Final Closing Indebtedness, the Final Transaction Expenses, the Final Working Capital, and the resulting Final Closing Consideration Amount: (i) if the Final Closing Consideration Amount is greater than the Estimated Closing Consideration Amount (such difference, the "Adjustment Surplus Amount"), (A) the Buyer shall make payment by wire transfer of immediately available funds to each of the Sellers in an amount equal to such Seller's Pro Rata Portion of the Adjustment Surplus Amount, provided, that such payment shall not exceed the sum of $150,000 in cash plus the value of the Adjustment Escrowed Shares (on the date hereof), in the aggregate, (B) the Buyer and the Sellers' Representative shall jointly instruct the Escrow Agent in accordance with the Escrow Agreement to release the Escrowed Adjustment Amount to the Paying Agent for further distribution ratably to the Sellers in accordance with their respective Pro Rata Portion, and (C) the Buyer and the Sellers' Representative shall jointly instruct the Escrow Agent in accordance with the Escrow Agreement to release the Adjustment Escrowed Shares to the Sellers in accordance with the Payment Allocation Schedule; (ii) if the Final Closing Consideration Amount is less than the Estimated Closing Consideration Amount (such deficit, which shall be expressed as a positive number, the "Adjustment Deficit Amount"): (A) to the extent the Escrowed Adjustment Amount is sufficient to pay the Buyer the full amount of the Adjustment Deficit Amount: (x) the Buyer and the Sellers' Representative shall jointly instruct the Escrow Agent in accordance with the Escrow Agreement to (1) release to the Buyer the Adjustment Deficit Amount (or such lesser amount equal to the Escrowed Adjustment Amount), by wire transfer of immediately available funds to an account designated in writing by the Buyer, and (2) deliver the remaining balance of the Escrowed Adjustment Amount, if any, after giving effect to the

The Adjustment Deficit Amount shall have a cap in the amount of the Escrowed Adjustment Amount plus the value of the Adjustment Escrowed Shares (on the date hereof). (iii) if the Final Closing Consideration Amount equals the Estimated Closing Consideration Amount, (A) the Buyer and the Sellers' Representative shall jointly instruct the Escrow Agent in accordance with the Escrow Agreement to release the Escrowed Adjustment Amount to the Paying Agent for further distribution ratably to the Sellers in accordance with their respective Pro Rata Portion and (B) the Buyer and the Sellers' Representative shall jointly instruct the Escrow Agent in accordance with the Escrow Agreement to release the Adjustment Escrowed Shares to the Sellers in accordance with the Payment Allocation Schedule. (f) Except in instances of Fraud, each of the parties hereto acknowledges and agrees that the adjustment provisions set forth in this Section 2.3 shall be the sole and exclusive remedy of Buyer and the Sellers with respect to (i) determining whether or not any adjustment would be made to the Estimated Closing Consideration Amount pursuant to this Section 2.3 (whether or not any such adjustment was, in fact, made), and (ii) determining the amount of any such adjustment. (g) Any payment made pursuant to this Section 2.32.3(d) shall be treated by the parties, to the extent permitted by Law, for U.S. federal income tax and other applicable Tax purposes, as an adjustment to the cash proceeds received by the Sellers in the Transaction. 2.4 Withholding. Each of the Buyer, its Affiliates, the Company, the Company Subsidiaries, the Paying Agent and the Escrow Agent shall be entitled to deduct and withhold from any amounts otherwise payable to a Person pursuant to this Agreement any amounts that are required to be deducted and withheld under applicable Tax Law.

For purposes of this Agreement, the portion of Taxes attributable to a Straddle Period that are allocated to the Pre-Closing Tax Period of such Straddle Period will be determined as follows: (i) in the case of any real property, personal property, or similar ad valorem Taxes ("Property Tax"), the amount of such Property Tax attributable to the Pre-Closing Tax Period of such Straddle Period will be deemed to be the amount of such Property Tax for the entire Straddle Period, multiplied by a fraction, the numerator of which is the number of days in such Straddle Period ending on and including the Closing Date, and the denominator of which is the number of total days in the entire Straddle Period; and (ii) in the case of any Tax that is based on income, sales, revenue, production, or similar items, or other Taxes that are not Property Taxes, the amount of any such Tax that is attributable to the Pre-Closing Tax Period of such Straddle Period will be determined based on an interim closing of the books as of and including the Closing Date. To the extent that Taxes are payable in advance (e.g., for a privilege period) and the gross receipts, income, operations, assets, margin, or capital comprising the base of such Tax is measured during a different Tax period, such Taxes shall be apportioned to the relevant Tax period during which the base of such Tax is measured, and if the Tax period to which such Tax is so allocated is a Straddle Period, then such Tax shall be determined in the manner set forth in Section 7.4(a)(i) or (ii), as applicable.

(d) Transfer Taxes. Any and all sales, use, transfer, value added, documentary, filing, recordation, registration, or other similar Taxes arising from the transactions contemplated by this Agreement ("Transfer Taxes") shall be borne and paid by the Sellers.

(ii) The Buyer shall have the right to control and defend any Tax Contest with counsel (including, for the avoidance of doubt, accountants) of its choice; provided, that with respect to any Tax items in any such Tax Contest for which the resulting Tax Liability the Sellers would be required to indemnify pursuant to this Agreement, (A) the Buyer shall keep the Sellers' Representative reasonably informed regarding the progress and substantive aspects of such Tax items in such Tax Contest, (B) the Sellers' Representative may participate (and retain separate counsel at the sole cost and expense of the Sellers to participate) in, but not control, the defense of such Tax items in such Tax Contest, including, to the extent the circumstances allow, having an opportunity to review any written materials prepared in connection with such Tax items in such Tax Contest and the right to attend any conferences relating thereto, and (C) the Buyer shall not settle or consent to the entry of any order, ruling, decision, or other similar determination or finding with respect to such Tax items in such Tax Contest without the prior written

(iii) Upon the written request of the Buyer to the Company at least thirty (30) days prior to the due date (including extensions) for filing the U.S. federal income tax return of the Company for the taxable year of the Company in which the Pre-Closing Spin-Out occurs, the New Arizona Holdco and the Company shall make an election pursuant to Treasury Regulation Section 1.245A-5(e)(3)(i) to close the taxable year of any Applicable Canadian Entity at the end of the day on the day on which the Pre-Closing Spin-Out occurs (any such timely requested election by the Buyer, a "Section 245A Election"), and each of the Buyer, the Company, and the Sellers shall cooperate to effect and preserve a valid and timely Section 245A Election, including that the Company and the New Arizona Holdco shall (and the Sellers shall cause the New Arizona Holdco to) enter into a binding written agreement to make any such Section 245A Election in compliance with the requirements set forth in Treasury Regulation Section 1.245A-5(e)(3)(i)(C)(2) (in form and substance reasonably acceptable to the Buyer) prior to the due date (including extensions) for filing the U.S. federal income tax return of the Company for the taxable year of the Company in which the Pre-Closing Spin-Out occurs.

In no event will the Sellers' Representative be required to advance its own funds on behalf of the Sellers or otherwise. Notwithstanding anything in this Agreement to the contrary, any restrictions or limitations on liability or indemnification obligations of, or provisions limiting the recourse against non-parties otherwise applicable to, the Sellers set forth elsewhere in this Agreement are not intended to be applicable to the indemnities provided to the Sellers' Representative hereunder The Sellers acknowledge that the Sellers' Representative shall not be required to expend or risk its own funds or otherwise incur any financial liability in the exercise or performance of any of its powers, rights, duties or privileges or pursuant to the administration of its duties as the Sellers' Representative hereunder. The foregoing indemnities will survive the Closing, the resignation or removal of the Sellers' Representative or the termination of this Agreement. (e) The Representative Reserve will be used for any expenses incurred by the Sellers' Representative. The Sellers will not receive any interest or earnings on the Representative Reserve and irrevocably transfer and assign to the Sellers' Representative any ownership right that they may otherwise have had in any such interest or earnings. The Sellers' Representative will hold these funds separate from its corporate funds and will not voluntarily make these funds available to its creditors in the event of bankruptcy. As soon as practicable following the completion of the Sellers' Representative's responsibilities, the Sellers' Representative will deliver any remaining balance of the Representative Reserve to the Paying Agent for further distribution to the Sellers. For tax purposes, the Representative Reserve will be treated as having been received and voluntarily set aside by the Sellers at the time of Closing. (f) Each Seller hereby acknowledges and agrees that the Buyer shall not have any Liability to any Seller with respect to, and the Sellers agree to hold the Buyer harmless from, any and all Losses incurred

The representations and warranties contained herein shall survive the Closing and shall remain in full force and effect until the date that is twelve (12) months from the Closing Date; provided, however, that (a) the Fundamental Representations (other than Section 5.13 (Taxes)) shall survive indefinitely, and (b) and the representations and warranties contained in Section 5.13 (Taxes) shall survive until ninety (90) days after the expiration of the applicable statute of limitations. The covenants and agreements contained in this Agreement that contemplate performance at or after Closing shall survive Closing for such period as shall be required for the party required to perform under such covenant or agreement to complete the performance required thereby (provided, however, that to the extent no such period for performance is specified, such covenants shall survive for the applicable statute of limitations), plus a period of three (3) months thereafter. If any party asserts a valid claim for indemnification, in good faith, prior to the expiration of the applicable survival period for any breach thereof, such claims shall survive until finally resolved. It is the express intent of the parties that, if the applicable survival period for a representation or warranty or covenant as contemplated by this Section 9.1 is shorter or longer than the statute of limitations period that would otherwise have been applicable to such representation or warranty or covenant, then by virtue of this Agreement, the applicable statute of limitations period with respect to such representation or warranty or covenant shall be reduced or extended to the shortened or longer survival period contemplated by this Section 9.1. The parties acknowledge and agree that the time period set forth in this Section 9.1 for the assertion of claims under this Agreement is the result of arm's-length negotiations among the parties and that they intend for such time period to be enforced as agreed among the parties. Any claims based on or arising out of Fraud shall survive Closing until the expiration of the applicable statute of limitations. 9.2 Indemnification. (a) Indemnification by the Sellers. Subject to the limitations set forth in this Article 9, from and after the Closing, each Seller shall indemnify and hold harmless the Buyer and each of its Affiliates, and the Representatives, successors and assigns of each of the foregoing Persons (each, a "Buyer Indemnified Person"), on a joint and several basis, from and against and in respect of any and all Losses incurred or suffered by the Buyer Indemnified Persons or any of them as a result of, arising out of or relating to, directly or indirectly: (i) any breach of, or inaccuracy in, the Fundamental Representations contained in Article 4 and Article 5 of this Agreement (for the purposes of determining the amount of Losses arising therefrom, as such representation or warranty would read if all qualifications as to materiality, including each reference to the defined term "Material Adverse Effect," were deleted therefrom); (ii) any breach of, or inaccuracy in, the representations and warranties (other than the Fundamental Representations) contained in Article 4 and Article 5 of this Agreement (for the purposes of determining the amount of Losses arising therefrom, as such representation or warranty would read if all qualifications as to materiality, including each reference to the defined term "Material Adverse Effect," were deleted therefrom); (iii) any breach or violation of any covenant or agreement of the Company or the Sellers to the extent required to be performed or complied with by the Company or such Seller at or prior to the Closing in or pursuant to this Agreement; (iv) any Pre-Closing Taxes (including all Pre-Closing Spin-Out Taxes);

&nbsp;&nbsp;&nbsp;&nbsp;- 70 – (v) any Liabilities related to the Pre-Closing Spin-Out; and (vi) any and all omissions or inaccuracies in the Payment Allocation Schedule. (b) Indemnification by the Buyer. Subject to the limitations set forth in this Article 9 from and after the Closing, the Buyer shall indemnify and hold harmless each Seller and each of its respective Affiliates and the Representatives, Affiliates, successors and assigns of each of the foregoing Persons (each, a "Seller Indemnified Person" and together with the Buyer Indemnified Persons, the "Indemnified Persons") from and against and in respect of any and all Losses incurred by the Seller Indemnified Persons as a result of, arising out of or relating to, directly or indirectly: (i) any breach or inaccuracy of any representation or warranty made by the Buyer contained in Article 6; or (ii) any breach or nonfulfillment of any covenant or agreement of the Buyer that is required to be performed pursuant to this Agreement. 9.3 Indemnification Procedure. (a) Each claim for which an Indemnified Person may seek indemnity under this Article 9 (each such claim, an "Indemnification Claim") shall be brought and resolved exclusively in accordance with this Section 9.3. The Indemnified Person shall promptly give written notice of an Indemnification Claim (each such notice, a "Claim Notice") to the party indemnifying such Indemnified Person pursuant to Section 9.2(a) or Section 9.2(b), as applicable (the "Indemnifying Person"). Each Claim Notice shall describe the Indemnification Claim in reasonable detail and shall indicate the amount (estimated, if necessary and to the extent possible) of the Loss that has been or may be suffered by the Indemnified Person. No delay in or failure to give a Claim Notice or the giving of an incomplete or inaccurate Claim Notice pursuant to this Section 9.3(a) shall adversely affect any of the other rights or remedies which the Indemnified Person has under this Agreement, or alter or relieve any Indemnifying Person of its obligation to indemnify the Indemnified Person, except and only to the extent that such delay or failure results in actual prejudice to the Indemnifying Person. The Indemnifying Person shall have thirty (30) days after its receipt of such Claim Notice to respond in writing to such Indemnification Claim. If the Indemnifying Person does not so respond within such 30-day period, the Indemnifying Person shall be deemed to have agreed to such claim and the Indemnifying Person's obligation to indemnify the Indemnified Person for the full amount of all Losses related to or resulting therefrom. If the Indemnifying Person timely delivers a written objection to the Indemnification Claim within such 30-day period, the Indemnifying Person and the Indemnified Person (or, if applicable, the Sellers' Representative) shall work in good faith to resolve the dispute for a period of thirty (30) days following delivery of such objection. If the parties are unable to resolve such dispute within such period (or such longer period as they may mutually agree), the dispute shall be resolved in accordance with the dispute resolution procedures set forth in this Agreement. For purposes of this Section 9.3, (i) if the Sellers comprise the Indemnifying Person, any references to the Indemnifying Person (except provisions relating to an obligation to make or a right to receive any payments) will be deemed to refer to the Sellers' Representative and (ii) if the Sellers comprise the Indemnified Person, any references to the Indemnified Person (except provisions relating to an obligation to make or a right to receive any payments) will be deemed to refer to the Sellers' Representative. (b) An Indemnifying Person shall have the right, exercisable by written notice to the Indemnified Person within fifteen (15) Business Days of receipt of a Claim Notice which relates to Losses arising or relating to a claim brought by a third party (each, a "Third Party Claim"), to assume and conduct the defense of any such Third Party Claim, in accordance with the limits set forth in this Agreement, with counsel selected by the Indemnifying Person and reasonably acceptable to the Indemnified Person;

------

![](ex21stockpurchaseagreeme076.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;- 71 – provided, however, that the Indemnifying Person shall have the right to assume and conduct the defense of any such Third Party Claim only if (i) the defense of such Third Party Claim by the Indemnifying Person does not, and will not, in the reasonable judgment of the Indemnified Person, be materially detrimental to or materially injure the Indemnified Person's relationships with any material business relation of the Indemnified Person, (ii) the Indemnified Person reasonably believes the Losses relating to such Third Party Claim would exceed the maximum amount the Indemnifying Person may be liable for hereunder or that the Indemnifying Person does not have sufficient financial resources to satisfy the amount of any adverse monetary judgement that is reasonably likely to result, (iii) the Third Party Claim solely seeks monetary damages, and (iv) the Third Party Claim does not relate to or otherwise arise in connection with Taxes or any criminal or regulatory enforcement Action (the conditions set forth in clauses (i) through (iv) are collectively referred to as the "Litigation Conditions"). If the Indemnifying Person does not assume the defense of a Third Party Claim in accordance with this Section 9.3(b), the Indemnified Person may continue to defend the Third Party Claim and the costs and expenses of such defense shall be additional Losses. If the Indemnifying Person has assumed the defense of a Third Party Claim as provided in this Section 9.3(b), the Indemnifying Person shall not be liable for any legal expenses subsequently incurred by the Indemnified Person in connection with the defense of the Third Party Claim; provided, however, that if (A) any of the Litigation Conditions cease to be met, (B) the Indemnifying Person fails to take reasonable steps necessary to defend diligently such Third-Party Claim or (C) the Indemnifying Person has been advised by its counsel that a reasonable likelihood exists of a conflict of interest between the Indemnifying Person and the Indemnified Person, the Indemnified Person may assume its own defense, and the Indemnifying Person shall be liable for all reasonable costs or expenses paid or incurred by the Indemnified Person in connection with such defense. The Indemnifying Person or the Indemnified Person, as the case may be, shall have the right to participate in (but not control), at its own expense, the defense of any Third Party Claim which the other is defending as provided in this Agreement. The Indemnifying Person, if it shall have assumed the defense of any Third Party Claim as provided in this Agreement, shall not, without the prior written consent of the Indemnified Person, consent to a settlement of, or the entry of any judgment arising from, any such Third Party Claim which (x) does not include as a term thereof the giving by the claimant or the plaintiff to the Indemnified Person a complete, unconditional release from all Liability in respect of such Third Party Claim, (y) grants any injunctive or equitable relief or includes an amount to be paid by any Person other than the Indemnifying Person, or (z) may reasonably be expected to have a material adverse effect on the business of the Indemnified Person. The Indemnified Person shall have the right to settle any Third Party Claim in its sole discretion, but only to the extent the defense of such Third Party Claim has not been assumed by the Indemnifying Person; provided, however, that any such settlement entered into without the prior written consent of the Indemnifying Person shall not be binding on such Indemnifying Person. For the avoidance of doubt, the procedures set forth in this Section 9.3(b) shall not apply to any Tax Contest, which shall be governed by Section 7.4(e) (c) Any payment that the Sellers are obligated to make to any Buyer Indemnified Person pursuant to this Article 9 will be made (i) first, from the funds then remaining in the Escrow Account, by release of funds to such Buyer Indemnified Person from the Escrow Account by the Escrow Agent pursuant to the terms and conditions of the Escrow Agreement, (ii) second, by offset against any Indemnity Escrowed Shares (valued on the date hereof), and (iii) thereafter, by the direct payment of the amount of the applicable Losses from the Sellers, on a joint and several basis. Notwithstanding the foregoing, any payment that the Sellers are obligated to make to any Buyer Indemnified Person pursuant to this Article 9 in respect of Pre- Closing Spin-Out Taxes will be made (A) first, from the remaining Escrowed Spin-Out Amount, by release of funds to such Buyer Indemnified Person from the Escrow Account by the Escrow Agent pursuant to the terms and conditions of the Escrow Agreement, (B) second, by offset against any Spin-Out Escrowed Shares (valued on the date hereof), (C) third, from the remaining Escrowed Amount, by release of funds to such Buyer Indemnified Person from the Escrow Account by the Escrow Agent pursuant to the terms and conditions of the Escrow Agreement, (D) by offset against any Indemnity Escrowed Shares (valued on the

(a) Except in the case of Fraud, in no event shall the aggregate indemnification obligations of the Seller Indemnifying Persons under Section 9.2(a)(i) exceed, in the aggregate, the sum of (i) Final Closing Consideration Amount and (ii) the aggregate value of the shares of Buyer Stock on the Closing Date. (b) Except in the case of Fraud, the Seller Indemnifying Persons shall not be liable to the Buyer Indemnified Persons for indemnification under Section 9.2(a)(ii) if the aggregate amount of all Losses in respect of indemnification under Section 9.2(a)(ii), exceeds $4,500,000. (c) If any Indemnified Person recovers any amounts in respect of Losses from any third party at any time after any Indemnifying Person has paid all or a portion of such Losses to the Indemnified Person pursuant to the provisions of this Article 9, and such Indemnified Person has therefore recovered from the Indemnifying Person and any relevant third party an amount which is greater than the Losses suffered or incurred by the Indemnifying Person (such amount being an "Excess Recovery"), then the Indemnified Person shall repay to the Indemnifying Person an amount (in aggregate) equal to the lesser of (i) the Excess Recovery; and (ii) the amount the Indemnifying Person has paid to the Indemnitee in respect of the relevant Losses. (d) The amount of any Losses that any Indemnified Person will be entitled to recover hereunder will be determined without duplication of recovery by reason of the state of facts giving rise to such Losses constituting a breach of more than one representation, warranty or covenant. 9.5 Knowledge and Investigation. The right of any Indemnified Person to indemnification pursuant to this Article 9 will not be affected by any investigation conducted or knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing, with respect to the accuracy of any representation or warranty, or performance of or compliance with any covenant or agreement. The waiver of any condition contained in this Agreement or in any Transaction Document based on the breach of any such representation or warranty, or on the performance of or compliance with any such covenant or agreement, will not affect the right of any Indemnified Person to indemnification pursuant to this Article 9 based on such representation, warranty, covenant or agreement. 9.6 Escrow Release. (a) Indemnity Escrow Release. (i) Any Escrowed Indemnity Amount and Indemnity Escrowed Shares (valued on the date hereof) in excess of $200,000 remaining as of the date that is twelve (12) months following the Closing Date (minus the aggregate amount claimed by the Buyer Indemnified Persons pursuant to a Claim Notice delivered prior to such date that are not fully resolved prior to such date) shall be released to the Paying Agent for distribution to the Sellers in accordance with their respective Pro Rata Portion as set forth on the Payment Allocation Schedule. At any time following such release, to the extent that the remaining Escrowed Indemnity Amount and Indemnity Escrowed Shares (valued on the date hereof) exceeds the aggregate amount claimed by the Buyer Indemnified Persons pursuant to a Claim Notice delivered prior to the date that is twelve (12) months following the Closing Date, the excess funds shall be promptly released

Each of the parties acknowledges that such consent and waiver is voluntary, that it has been carefully considered, and that the parties have consulted with counsel or have been advised they should do so in connection herewith. The covenants, consent and waiver contained in this Section 11.16 shall not be deemed exclusive of any other rights to which Spencer Fane LLP is entitled whether pursuant to law, contract, or otherwise. 11.17 Attorney-Client Privilege. All communications prior to Closing between the Company, on the one hand, and Spencer Fane LLP, on the other hand, relating to the negotiation, preparation, execution and delivery of this Agreement and the consummation of the transactions contemplated hereby (the "Privileged Communications") shall be deemed to be attorney-client privileged and the expectation of client confidence relating thereto shall survive Closing, and from and after Closing shall belong solely to Christopher Bryan, Bobby Williams, Craig Cigich, and Kjell Stakkestad (the "Privilege Holders") and shall not pass to or be claimed by Buyer or the Company. Accordingly, from and after Closing, Buyer and the Company shall neither request nor have access to any Privileged Communications or to the files of Spencer Fane LLP relating to such engagement. Without limiting the generality of the foregoing, from and after the Closing, (i) the Privilege Holders (and not Buyer or the Company) shall be the sole holders of the attorney- client privilege with respect to such engagement, and none of Buyer or the Company shall be a holder thereof, (ii) to the extent that files of Spencer Fane LLP in respect of such engagement constitute property of the client, only the Privilege Holders (and not Buyer nor the Company) shall hold such property rights and (iii) Spencer Fane LLP shall have no duty whatsoever to reveal or disclose any such attorney-client communications or files to Buyer or the Company by reason of any attorney-client relationship between Spencer Fane LLP and the Company. The above-stated restrictions pertain not only to documents but to their existence, substance, and contents, all of which shall be and remain in the complete and unfettered custody and control of the Privilege Holders. In the event that after Closing a dispute arises between Buyer or its Affiliates (including the Company), on the one hand, and a third party other than any of the Privilege Holders, on the other hand, neither Buyer nor any of its Affiliates (including the Company) may waive the attorney-client privilege held by the Privilege Holders without the prior written consent of a majority of the Privilege Holders. In the event that Buyer or any of its Affiliates (including the Company) is legally required by Governmental Order or otherwise legally required to access or obtain a copy of all or a portion of the Privileged Communications, to the extent (x) permitted by applicable Law, and (y) advisable in the opinion of Buyer's counsel, then Buyer shall immediately (and, in any event, within five (5) Business Days) notify Privilege Holders in writing so that Privilege Holders can seek a protective order. In furtherance of the foregoing, each of the parties agrees that (A) no waiver is intended by failing to remove all Privileged Communications from the Company's files and computer systems, (B) after Closing the parties will use commercially reasonable efforts to take the steps necessary to ensure the Privileged Communications are held and controlled by the Privilege Holders, and (C) at the Privilege Holders' written request, Buyer shall, at the Privilege Holders' discretion, promptly return to the Privilege Holders all copies, whether in written, electronic, or other form or media, of the Privileged Communications, or destroy all such copies and certify in writing to the Privilege Holders that such Privileged Communications have been destroyed. Buyer agrees that after Closing none of Buyer, the Company, or their Affiliates will (1) access or review the Privileged Communications in connection with any action, litigation, claim, or dispute against or involving the Sellers or (2) use or assert the Privileged Communications against the Sellers in any action, litigation, claim, or dispute against or involving the Sellers.

Capitalized terms used but not defined herein shall have the meanings assigned to them in the Purchase Agreement (as defined below). WHEREAS, Buyer, KinetX, Inc., a California corporation (the "Company"), the shareholders of the Company signatory thereto (each a "Seller" and collectively, the "Sellers"), and the Sellers' Representative have entered into that certain Stock Purchase Agreement, dated August [●], 2025 (the "Purchase Agreement"), pursuant to which Buyer will purchase all of the issued and outstanding capital stock of the Company (the "Stock Purchase"); WHEREAS, pursuant to the Purchase Agreement, Buyer has agreed to deposit certain funds into two escrow accounts (the "Escrow Accounts") at the Closing by wire transfer of immediately available cash funds, with such funds to be held, invested and disbursed by the Escrow Agent, which funds shall be available to satisfy any amounts owed to Buyer pursuant to Section 2.3 and Article 9 of the Purchase Agreement in accordance with the terms and conditions of this Escrow Agreement; WHEREAS, Buyer, the Sellers' Representative and PNC Bank, National Association (the "Paying Agent") have entered into that certain Paying Agent Agreement of even date herewith (the "Paying Agent Agreement") pursuant to which the Paying Agent has established an account (the "Paying Account") for the purpose of receiving certain funds payable under the Purchase Agreement, including amounts to be disbursed pursuant to this Escrow Agreement; WHEREAS, pursuant to the Purchase Agreement, Buyer shall cause its transfer agent (the "Transfer Agent") to deposit certain Escrow Shares (defined below) into the Escrow Accounts at the Closing, with such Escrow Shares to be held and disbursed at the direction of the Escrow Agent in accordance with the terms and conditions of this Escrow Agreement; and WHEREAS, the Parties desire to set forth their understandings with regard to the Escrow Accounts established by this Escrow Agreement. NOW, THEREFORE, in consideration of the premises herein, the parties hereto agree as follows: I. Terms and Conditions 1.1. Appointment of and Acceptance by Escrow Agent. Buyer and the Sellers' Representative hereby appoint PNC Bank, National Association to act as the escrow agent for the purposes set forth herein, and PNC Bank, National Association hereby accepts such appointment and agrees to perform its duties as provided herein. 1.2.

------

![](ex21stockpurchaseagreeme096.jpg)

2 Buyer in respect of any shares then held in the Escrow Account while such account remains outstanding (the "Adjustment Escrow Shares" which will be specified by the Buyer if in book entry or certificated form, and together with the Adjustment Escrow Cash, the "Adjustment Escrow Funds") and (b) in the second account, (i) pursuant to the wire instructions set forth on Schedule A hereto, in immediately available funds, US$[______], representing the Escrowed Indemnity Amount referred to in the Purchase Agreement (together with all interest and earnings thereon, and less any disbursements hereunder, the "Indemnity Escrow Cash" and together with the Adjustment Escrow Cash, the "Escrow Cash") and (ii) the share portion of [______] shares of Buyer stock and including any additional shares of Buyer stock subsequently issued or distributed by the Buyer in respect of any shares then held in the Escrow Account while such account remains outstanding (the "Indemnity Escrow Shares" which will be specified by the Buyer if in book entry or certificated form, and together with the Indemnity Escrow Cash, the "Indemnity Escrow Funds") (the Adjustment Escrow Shares together with the Indemnity Escrow Shares, the "Escrow Shares") (the Indemnity Escrow Funds together with the Adjustment Escrow Funds, the "Escrow Funds"). 1.3. Escrow Shares. (a) The Escrow Agent shall hold the Escrow Shares as a book position registered by the Buyer in the name PNC Bank, National Association, as Escrow Agent for the benefit of the Sellers. The Transfer Agent shall maintain the Escrow Shares as a book-entry position registered in the name of "PNC Bank, National Association, as Escrow Agent for the benefit of the Sellers". Transfer Agent will provide evidence to the Escrow Agent by electronic mail confirming the total Escrow Shares. The Escrow Shares shall not be liquidated or otherwise reinvested, provided that any cash, stock, property or rights therefor, distributed or paid or payable in respect of the Escrow Shares shall constitute part of the Escrow Funds. Subject to Section 1.4 below, any amounts received by the Escrow Agent on account of holding the Escrow Shares as nominee for the Sellers shall be held in the form received. Until such time as the Escrow Shares are delivered to the Sellers in accordance with Section 1.4 below (or returned or otherwise transferred to, cancelled or redeemed by Buyer), the applicable Seller shall be the beneficial owner of the applicable portion of the Escrow Shares that are held pursuant to this Escrow Agreement, and shall possess during the period of time in which such Escrow Shares are held or retained by the Escrow Agent as nominee for the Sellers all rights with respect to such Escrow Shares, except the right of possession or transfer thereof. The Escrow Agent shall not be required to vote any of the shares comprising the Escrow Shares. (b) Buyer will cause the Transfer Agent to not require a Medallion Signature Guarantee to transfer the book-entry Escrow Shares from PNC Bank, National Association to the respective Seller accounts. In lieu of a Medallion Signature Guarantee, a spreadsheet is to be provided by Escrow Agent to the Transfer Agent to include the total number of Escrow Shares to be issued to each Seller. Buyer will give Transfer Agent precise and clear direction via email correspondence excluding the need for a Medallion Signature Guarantee and accepting the detailed spreadsheet as direction in which to transfer the Escrow Shares. (c) Any dividends made with respect to the Escrow Shares that are held pursuant to this Escrow Agreement shall be held by the Escrow Agent on behalf of the Sellers as part of the Escrow Funds for further distribution to the Sellers holding the applicable Escrow Shares to which such dividends relate pursuant to a Joint Written Instruction (as defined below), except that any cash dividends made with respect to such Escrow Shares shall be promptly paid to the Paying Agent upon receipt of a Joint Written Instruction to the Escrow Agent for further distribution to the applicable Sellers. 1.4.

4 damages that are directly attributable to the Escrow Agent's fraud, gross negligence, bad faith or willful misconduct in performing duties as outlined in this Escrow Agreement. (b) The Escrow Agent shall be fully protected (i) in acting in reliance upon any certificate, statement, request, notice, advice, instruction, direction, other agreement or instrument or signature reasonably and in good faith provided by the Sellers' Representative or Buyer with respect to such Party's information and reasonably believed by the Escrow Agent to be genuine, (ii) in assuming in good faith that any person purporting to give the Escrow Agent any of the foregoing in connection with either this Escrow Agreement or the Escrow Agent's duties has been duly authorized to do so and (iii) in acting or failing act in good faith in accordance with the terms of this Escrow Agreement on the advice of outside counsel retained by the Escrow Agent, provided that the Escrow Agent shall remain liable where the actions taken or omitted by the Escrow Agent in reliance upon clauses (i), (ii), and (iii) herein are determined to constitute the Escrow Agent's fraud, bad faith, willful misconduct, or gross negligence. (c) The Escrow Agent shall have no liability with respect to the transfer or distribution of any funds effected by the Escrow Agent pursuant to wiring or transfer instructions provided in a Joint Written Instruction to the Escrow Agent in accordance with the provisions of this Escrow Agreement. The Escrow Agent shall be entitled to rely upon all bank and account information provided to the Escrow Agent by the applicable Authorized Representative of each of Buyer and the Sellers' Representative set forth on Exhibit A-1 and Exhibit A-2 in a Joint Written Instruction. The Escrow Agent shall have no duty to verify or otherwise confirm any written wire transfer instructions except as set forth in Section 2.3 below, but it may do so in its discretion on any occasion without incurring any liability to any party for failing to do so on any other occasion. The Escrow Agent shall process all wire transfers based on bank identification and account numbers rather than the names of the intended recipient of the funds, even if such numbers pertain to a recipient other than the recipient identified in the payment instructions; provided, however, that the Escrow Agent shall use commercially reasonable efforts to review such wire transfer instructions for inconsistencies that would reasonably be expected to result in erroneous wire transfers. The Escrow Agent shall use commercially reasonable efforts to resolve any such inconsistencies by using verifying or confirming such wire transfer instructions with the applicable Authorized Representative of Buyer or Sellers' Representative. In connection with any payments that the Escrow Agent is instructed to make by wire transfer, the Escrow Agent shall not be liable for the acts or omissions of (i) the Sellers' Representative, Buyer or other person providing such instructions, including without limitation errors as to the amount, bank information or bank account number; or (ii) any other person or entity, including without limitation any Federal Reserve Bank, any transmission or communications facility, any funds transfer system, any receiver or receiving depository financial institution, and no such person or entity shall be deemed to be an agent of the Escrow Agent. Any wire transfers of funds made by the Escrow Agent pursuant to this Escrow Agreement will be made subject to and in accordance with the Escrow Agent's usual and ordinary wire transfer procedures in effect from time to time. (d) No provision of this Escrow Agreement shall require the Escrow Agent to risk or advance its own funds or otherwise incur any financial liability or potential financial liability in the performance of its duties or the exercise of its rights under this Escrow Agreement. The Escrow Agent shall not be obligated to take any legal action or to commence any proceedings in connection with this Escrow Agreement or any property held hereunder or to appear in, prosecute or defend in any such legal action or proceedings. (e) Buyer understands and acknowledges that The PNC Financial Services Group, Inc., a Pennsylvania corporation ("PNC") offers a diversified set of financial products and services, and may currently, or in the future, have relationships with parties whose interest may conflict with those of the Buyer.

5 2.3. Security Procedure For Funds Transfers. The Escrow Agent shall confirm each funds transfer instruction received in the name of a Party by telephone call-back to an Authorized Representative specified on Exhibit A-1 or Exhibit A-2 at the telephone number specified for such Authorized Representative on Exhibit A-1 or Exhibit A-2, as applicable. The Parties acknowledge that the security procedures set forth herein are commercially reasonable. Once delivered to the Escrow Agent, Exhibit A- 1 or Exhibit A-2 may be revised or rescinded only by a writing signed by an Authorized Representative of the applicable Party. Such revisions or rescissions shall be effective only after actual receipt and following such period of time as may be necessary to afford the Escrow Agent a reasonable opportunity to act on it. If a revised Exhibit A-1 or Exhibit A-2 or a rescission of an existing Exhibit A-1or Exhibit A-2 is delivered to the Escrow Agent by an entity that is a successor-in-interest to such Party, such document shall be accompanied by additional documentation satisfactory to the Escrow Agent showing that such entity has succeeded to the rights and responsibilities of the applicable Authorized Representative of each of Buyer and the Sellers' Representative under this Escrow Agreement. Buyer and the Sellers' Representative understand that the Escrow Agent's inability to receive or confirm funds transfer instructions pursuant to the above security procedure may result in a delay in accomplishing such funds transfer, and agree that the Escrow Agent shall not be liable for any loss caused by any such delay. 2.4. Depository Role. The Escrow Agent acts hereunder as a depository only, and is not responsible or liable in any manner whatsoever for the sufficiency, correctness, genuineness or validity of the subject matter of this Escrow Agreement or any part thereof, or of any person executing or depositing such subject matter. 2.5. No Duty to Notify.

NOW, THEREFORE, in consideration of the premises set forth above, which are incorporated in this Agreement as if fully set forth below, and intending to be legally bound hereby, the parties hereby agree as follows: 1. Lock-Up Provisions. (a) Holder hereby agrees not to, without the prior written consent of Buyer, during the period (the "Lock-Up Period") commencing from the Closing Date and ending on the earlier of (A) the date that is six (6) months following the Closing Date and (B) the date on which Buyer consummates a subsequent liquidation, merger, capital stock exchange, reorganization, or other similar transaction which results in all of the stockholders of Buyer having the right to exchange their shares of Buyer Stock for cash, securities or other property: (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidation with respect to or decrease a call equivalent position within the meaning of Section 16 of the Securities and Exchange Act of 1934, as amended, and the rules and regulations of the Securities and Exchange Commission promulgated thereunder with respect to, any Restricted Securities, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Restricted Securities, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce the intention to effect any transaction specified in clause (i) or (ii) (any of the foregoing described in clauses (i), (ii) or (iii), a "Prohibited Transfer"). The foregoing sentence shall not apply to the transfer of any or all of the Restricted Securities owned by Holder (each, a "Permitted Transferee"): (I) in the case of an

entity, transfers (A) to another entity that is an Affiliate of the Holder, (B) as part of a distribution to members, partners or stockholders of Holder and (C) to officers or directors of Holder, any Affiliate or family member of any of Holder's officers or directors, or to any members, officers, directors or employees of Holder or any of its Affiliates; (II) in the case of an individual, transfers by gift to members of the individual's immediate family or to a trust, the beneficiary of which is a member of one of the individual's immediate family, an Affiliate of such person; (III) to a charitable organization; (IV) in the case of an individual, transfers by virtue of laws of descent and distribution upon death of the individual; (V) in the case of an individual, transfers pursuant to a qualified domestic relations order; (VI) in the case of an entity, transfers by virtue of the laws of the state of the entity's organization and the entity's organizational documents upon dissolution of the entity; (VII) transfers to satisfy any U.S. federal, state or local income tax obligations of Holder (or its direct or indirect owners) to the extent necessary to cover any tax liability as a direct result of the transactions contemplated by the Purchase Agreement; (VIII) by private sales or transfers made in connection with the consummation of the transactions contemplated by the Purchase Agreement at prices no greater than the price at which the Restricted Securities were originally purchased; or (IX) in the form of a pledge of Restricted Securities in a bona fide transaction as collateral to secure obligations pursuant to lending or other financing arrangements between a Holder (or its Affiliates), on the one hand, and a third party, on the other hand, for the benefit of such Holder and/or its Affiliates; provided, however, that during the Lock-Up Period such third party shall not be permitted to foreclose upon such Restricted Securities or otherwise be entitled to enforce its rights or remedies with respect to the Restricted Securities, including, without limitation, the right to vote, transfer or take title to or ownership of such Restricted Securities; provided, however, that it shall be a condition to any transfer pursuant to clauses (I) through (IX) above that the Permitted Transferee executes and delivers to Buyer an agreement stating that the transferee is receiving and holding the Restricted Securities subject to the provisions of this Agreement applicable to Holder, and there shall be no further transfer of such Restricted Securities except in accordance with this Agreement. Holder further agrees to execute such agreements as may be reasonably requested by Buyer that are consistent with the foregoing or that are necessary to give further effect thereto. The restrictions set forth herein shall not restrict Holder from making a request for inclusion of its Restricted Securities in any registration statement pursuant to any registration rights agreement between Buyer and the Holder, provided that no public filing or public disclosure relating to such sale of securities is made during the Lock-Up Period.

(a) In no event shall either Seller or IM be liable to the other for any special, indirect, incidental or consequential damages (including, but not limited to, lost profits, lost business opportunities, loss of use or equipment down time, and loss of or corruption to data) arising out of or relating to this Agreement, regardless of the legal theory under which such damages are sought, and even if the parties have been advised of the possibility of such damages or loss. (b) Seller agrees, to the extent permitted by law, to indemnify and hold harmless but shall have no obligation to defend IM and its officers, directors and employees (collectively "IM") from and against liability for damages to the extent actually caused by the negligent acts, errors or omissions of Seller and its subcontractors, or anyone for whom the Seller is legally liable, in the performance of professional services under this Agreement. Seller's obligation to indemnify IM shall continue for a period of one year following the termination of the Agreement.

IM-QMS-FRM-BUS-002 Professional Services Agreement Revision: Issue 4 Final Effective Date: 9/01/2023 liability for damages to the extent actually caused by the negligent acts, errors or omissions of IM and its Sellers, subcontractors, Consultants, or anyone for whom IM is legally liable, in connection with this Agreement. IM's obligation to indemnify Seller shall continue for a period of one year following the termination of the Agreement. (d) Neither IM nor Seller shall be obligated to indemnify the other party in any manner whatsoever for the other party's own negligence or for the negligence of others. (e) Any claim by IM against Seller relating to this Agreement, other than in warranty, must be made in writing and presented to Seller within one year after the earlier of: (1) the date on which the IM accepts the deliverable(s) at issue; or (2) the date on which Seller completes performance of the Services specified in this Agreement. 17. Non-Waiver of Rights. The failure of either party to insist upon performance of any provision of this Agreement, or to exercise any right, remedy or option provided herein, shall neither be construed as a waiver of the right to assert any of the same or to rely on any such terms or conditions at any time thereafter, nor in any way affect the validity of this Agreement. 18. Severability. If any covenant, condition, term, or provision contained in this Agreement is held or finally determined to be invalid, illegal, or unenforceable in any respect, in whole or in part, such covenant, condition, term, or provision shall be severed from this Agreement, and the remaining covenants, conditions, terms and provisions contained herein shall continue in force and effect, and shall in no way be affected, prejudiced or disturbed thereby. 19. Conflicting Provisions. This Agreement and all of the exhibits, schedules, and documents attached hereto are intended to be read and construed in harmony with each other, but in the event any provision in any attachment conflicts with any provision of this Agreement, then this Agreement shall be deemed to control, and such conflicting provision shall be deemed removed and replaced with the governing provision herein. 20. Assignment. Neither party may sell, assign, transfer, or otherwise convey any of its rights or delegate any of its duties under this Agreement without the prior written consent of the other party, which consent may not be unreasonably withheld.

Change in Control of Seller. Prior to a potential change in control of Seller and at least ninety (90) days prior to the proposed effectiveness of such change in control, Seller will promptly notify IM in writing thereof, and provide the identity of the potential new controlling party and information on such party and the transaction as IM may request, consistent with applicable law and confidentiality restrictions. 22.

The captions and headings used in this Agreement are solely for the convenience of the parties, and the text of the Agreement shall govern in the event of any conflict or ambiguity.

Additionally, notices sent by any other means (i.e., facsimile, overnight delivery, courier, etc.) may be acceptable subject to written confirmation of both the transmission and receipt of the notice. 28. Relationship of Parties. Seller is an independent Seller in all respects with regard to this Agreement. Nothing contained in this Agreement shall: (1) authorize or empower either party to act as partner or agent of the other party in any manner; (2) authorize, or empower or deem one party to assume or create any obligation or responsibility whatsoever, express or implied, on behalf of or in the name of any other party; or (3) authorize, empower or deem a party to bind any other party in any manner or make any representation, warranty, covenant, agreement, or commitment on behalf of any other party. 29.

&nbsp;&nbsp;&nbsp;&nbsp;2 notwithstanding any rights of publicity, privacy or otherwise (whether or not statutory) anywhere in the world and without any further compensation, the Company may and is hereby authorized to use my name, likeness and voice in connection with promotion of its business, products and services, and to allow others to do the same. 3. Proprietary Information. a. Definition; Restrictions on Use. I agree that all Assigned Inventions (and all other financial, business, legal and technical information regarding or relevant to any Company Interest that is not generally publicly known), including the identity of and any other information relating to the Company's employees, Affiliates and Business Partners (as such terms are defined below), that I develop, learn or obtain during my employment or engagement, or that are received by or for the Company in confidence, constitute "Proprietary Information." I will hold in strict confidence and not directly or indirectly disclose or use any Proprietary Information, except as required within the scope of my employment or engagement. My obligation of nondisclosure and nonuse of Proprietary Information under this Section shall continue until I can document that it is or becomes readily generally available to the public without restriction through no fault of mine (understanding that breach of this Agreement would be such a fault) or, if a court requires a shorter duration, then the maximum time allowable by law will control. Furthermore, I understand that this Agreement does not affect my immunity under 18 USC Sections 1833(b) (1) or (2), which read as follows: (1) An individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (A) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. (2) An individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual (A) files any document containing the trade secret under seal; and (B) does not disclose the trade secret, except pursuant to court order. b. Upon Termination. Upon termination of my employment or engagement (for any or no reason, whether voluntary or involuntary), I will promptly identify and, as directed by the Company, destroy, delete or return to the Company all items containing or embodying Proprietary Information, except that I may keep my personal copies of (i) my compensation records; (ii) materials distributed to shareholders generally and (iii) this Agreement. c. Company Systems. I also recognize and agree that I have no expectation of privacy with respect to the Company's networks, telecommunications systems or information processing systems (including, without limitation, stored computer files, email messages and voicemail messages or other devices (including personal devices)) in which Company Proprietary Information resides, is stored or is passed through (collectively, "Company Systems"), and in order to ensure compliance with work rules and safety concerns, the Company or its agents may monitor, at any time and without further notice to me, any Company Systems and any of my activity, files or messages on or using any Company Systems, regardless of whether such activity occurs on equipment owned by me or the Company. I further agree that any property situated on the Company's premises and owned, leased or otherwise possessed by the Company, including computers, computer files, email, voicemail, storage media, filing cabinets or other work areas, is subject to inspection by Company personnel at any time with or without notice. I understand and acknowledge that (A) any such searches or monitoring efforts are not formal accusations of wrongdoing but rather part of the procedure of an investigation and (B) refusal to consent to such a search may be grounds for discipline. 4. Employment at Will. I agree that this Agreement is not a contract for any particular term. I have the right to resign and the Company has the right to terminate my employment or other engagement at will, at any time, for any or no reason, with or without cause. This Agreement does not purport to set forth all of the terms and conditions of my employment or other engagement, and as an employee or consultant of the Company, I have obligations to the Company which are not described in this Agreement. However, the terms of this Agreement govern over any such terms that are inconsistent with this Agreement and supersede the terms of any similar form that I may have previously signed. This Agreement can only be changed by a subsequent written agreement signed by the Chief Executive Officer or President of the Company, or an officer designee authorized in writing by the foregoing or the Company's Board of Directors. 5. Protected Activity Not Prohibited. I understand that nothing in this Agreement limits or prohibits me from filing a charge or complaint with, or otherwise communicating or cooperating with or participating in any investigation or proceeding that may be conducted by, any federal, state or local government agency or commission, including the Securities and Exchange Commission, the Equal Employment Opportunity Commission, the Occupational Safety and Health Administration, the National Labor Relations Board, the state division of human rights, a local commission on human rights, or law enforcement ("Government Agencies"), or from communicating with my attorney, including disclosing documents or other information as permitted by law, without giving notice to, or receiving authorization from, the Company. Notwithstanding the foregoing, in making any such disclosures or communications, I agree to take all reasonable precautions to prevent any unauthorized use or disclosure of any information that may constitute Proprietary Information to any parties other than the Government Agencies or my attorney. 6. Survival. I agree that any change or changes in my title, duties, compensation, or equity interest, in each case, associated with my employment or other engagement, after the signing of this Agreement shall not affect the validity or scope of this Agreement. I agree that the terms of this Agreement, and any obligations I have hereunder, shall continue in effect after termination of my employment or other engagement, regardless of the reason, and whether such termination is voluntary or involuntary, and that the Company is entitled to communicate my obligations under this Agreement to any of my potential or future employers. I will provide a copy of this Agreement to any potential or future employers of mine, so that they are aware of my obligations hereunder. This Agreement, and any obligations I have hereunder, also shall be binding upon my heirs, executors, assigns and administrators, and shall inure to the benefit of the Company, its Affiliates, successors and assigns. This Agreement and any rights and obligations of the Company hereunder may be freely assigned and transferred by the Company, in whole or part, to any third party. 7. Miscellaneous. Any dispute in the meaning, effect or validity of this Agreement shall be resolved in accordance with the laws of the State of Delaware (provided that if I am a resident of California, any disputes shall be resolved in accordance with the laws of the State of California), without regard to the conflict of laws provisions thereof. Any legal action or proceeding relating to this Agreement shall be brought exclusively in the state or federal courts located in or with jurisdiction over Texas (provided that if I am a resident of California, any legal action or proceeding shall be brought exclusively in the state or federal courts located in or with jurisdiction over San Francisco County, California), and each party consents to the jurisdiction thereof; however, the Company may seek injunctive relief and specific performance in any court of competent jurisdiction. The failure of either party to enforce its rights under this Agreement at any time for any period shall not be construed as a waiver of such rights. Unless expressly provided otherwise, each right and remedy in this Agreement is in addition to any other right or remedy, at law or in equity, and the exercise of one right or remedy will not be deemed a waiver of any other right or remedy. If one or more provisions of this Agreement is held to be illegal or unenforceable under applicable law, such illegal or unenforceable portion shall be limited or excluded from this Agreement to the minimum extent required so that this Agreement shall otherwise remain in full force and effect and enforceable. I acknowledge and agree that any breach or threatened breach of this Agreement will cause irreparable harm to the Company for which damages would not be an adequate remedy, and, therefore, the Company is entitled to injunctive relief with respect thereto (without the necessity of posting any bond) in addition to any other remedies.

&nbsp;&nbsp;&nbsp;&nbsp;A - 1 of 3 Appendix A If I am employed by the Company in the State of California, the following provision applies: CALIFORNIA LABOR CODE § 2870 Inventions Made by an Employee (a) Any provision in an employment agreement which provides that an employee shall assign, or offer to assign, any of his or her rights in an invention to his or her employer shall not apply to an invention that the employee developed entirely on his or her own time without using the employer's equipment, supplies, facilities, or trade secret information except for those inventions that either: (1) Relate at the time of conception or reduction to practice of the invention to the employer's business, or actual or demonstrably anticipated research or development of the employer; or (2) Result from any work performed by the employee for his employer. (b) To the extent a provision in an employment agreement purports to require an employee to assign an invention otherwise excluded from being required to be assigned under subdivision (a), the provision is against the public policy of this state and is unenforceable. If I am employed by the Company in the State of Delaware, the following provision applies: DELAWARE CODE, TITLE 19 § 805 Employee's right to certain inventions. Any provision in an employment agreement which provides that the employee shall assign or offer to assign any of the employee's rights in an invention to the employee's employer shall not apply to an invention that the employee developed entirely on the employee's own time without using the employer's equipment, supplies, facility or trade secret information, except for those inventions that: (1) relate to the employer's business or actual or demonstrably anticipated research or development, or (2) result from any work performed by the employee for the employer. To the extent a provision in an employment agreement purports to apply to the type of invention described, it is against the public policy of this State and is unenforceable. An employer may not require a provision of an employment agreement made unenforceable under this section as a condition of employment or continued employment. If I am employed by the Company in the State of Illinois, the following provision applies: ILLINOIS COMPILED STATUTES 765 § 1060/2 Employee rights to inventions - conditions. (1) A provision in an employment agreement which provides that an employee shall assign or offer to assign any of the employee's rights in an invention to the employer does not apply to an invention for which no equipment, supplies, facilities, or trade secret information of the employer was used and which was developed entirely on the employee's own time, unless (a) the invention relates (i) to the business of the employer, or (ii) to the employer's actual or demonstrably anticipated research or development, or (b) the invention results from any work performed by the employee for the employer. Any provision which purports to apply to such an invention is to that extent against the public policy of this State and is to that extent void and unenforceable. The employee shall bear the burden of proof in establishing that his invention qualifies under this subsection. (2) An employer shall not require a provision made void and unenforceable by subsection (1) of this Section as a condition of employment or continuing employment. This Act shall not preempt existing common law applicable to any shop rights of employers with respect to employees who have not signed an employment agreement. (3) If an employment agreement entered into after January 1, 1984, contains a provision requiring the employee to assign any of the employee's rights in any invention to the employer, the employer must also, at the time the agreement is made, provide a written notification to the employee that the agreement does not apply to an invention for which no equipment, supplies, facility, or trade secret information of the employer was used and which was developed entirely on the employee's own time, unless (a) the invention relates (i) to the business of the employer, or (ii) to the employer's actual or demonstrably anticipated research or development, or (b) the invention results from any work performed by the employee for the employer. If I am employed by the Company in the State of Kansas, the following provision applies: KANSAS CODE § 44-130 Employment agreements assigning employee rights in inventions to employer; restrictions; certain provisions void; notice and disclosure. (a) Any provision in an employment agreement which provides that an employee shall assign or offer to assign any of the employee's rights in an invention to the employer shall not apply to an invention for which no equipment, supplies, facilities or trade secret information of the employer was used and which was developed entirely on the employee's own time, unless: (1) The invention relates to the business of the employer or to the employer's actual or demonstrably anticipated research or development; or (2) the invention results from any work performed by the employee for the employer. (b) Any provision in an employment agreement which purports to apply to an invention which it is prohibited from applying to under subsection (a), is to that extent against the public policy of this state and is to that extent void and unenforceable. No employer shall require a provision made void and unenforceable by this section as a condition of employment or continuing employment. (c) If an employment agreement contains a provision requiring the employee to assign any of the employee's rights in any invention to the employer, the employer shall provide, at the time the agreement is made, a written notification to the employee that the agreement does not apply to an invention for which no equipment, supplies, facility or trade secret information of the employer was used and which was developed entirely on the employee's own time, unless: (1) The invention relates directly to the business of the employer or to the employer's actual or demonstrably anticipated research or development; or (2) the invention results from any work performed by the employee for the employer.
