It is mutually recognized and agreed that the Business being acquired by Buyer hereunder is conducted throughout the World and that the geographical scope, the periods of restrictions and restraints imposed by this Section 7.02 are fair and reasonable and required for the protection of Buyer and its Affiliates and a significant inducement for Buyer to enter into this Agreement and the transactions contemplated hereby. It is further recognized and agreed that irreparable injury may result to Buyer and its Affiliates, their respective business and properties in the event of a breach or threatened breach of this covenant by Seller or any of its Affiliates, that the amount or extent of a breach or threatened breach of this covenant by Seller or any of its Affiliates, that the amount or extent of damages would be difficult if not impossible to ascertain and therefore, that any remedy at law for any breach by any of them of this covenant will be inadequate.

           (e) Covenants Independent. The covenants contained in this Section 7.02 shall be construed and enforced independently of each other and independently of any other provision of this Agreement or any other understanding or agreement between the parties, and the existence of any claim or cause of action of Seller against Buyer, of whatever nature, shall not constitute a defense to the enforcement of the covenants contained herein against Seller.

     Section 7.03. Transition and Further Assurances.

           (a) Seller will refer all customer, supplier and other inquiries relating to the Business to Buyer from and after the Closing and otherwise reasonably cooperate with Buyer in transitioning the Business to Buyer. In this regard, Seller agrees to cooperate with and assist the Buyer with transition matters regarding IT, accounting and

human resources during the sixty (60) day timeframe following Closing at no fee or expense to Buyer (provided that any direct out-of-pocket third party expenses, if any, shall be paid by Buyer). If Buyer requests cooperation and assistance beyond sixty (60) days following Closing, Buyer shall pay Seller a mutually agreeable, reasonable fee. Under no circumstances shall Seller be obligated to provide any assistance to Buyer beyond 180 days after Closing. As used in this section, cooperation and assistance with transition matters does not, under any circumstances, include or require the Seller to provide administrative services or provide on-going human resource services to employees of the Business employed by Buyer.

           (b) Seller shall, at any time and from time to time after the Closing Time, upon the reasonable request of Buyer and at Seller’s sole cost and expense, execute, acknowledge and deliver or cause to be executed, acknowledged and delivered all such further deeds, assignments, transfers, conveyances, powers of attorney and assurances and take such other action as may be necessary to assign, transfer, grant, convey the Purchased Assets or Assumed Obligations to Buyer or otherwise to carry out the purpose and intent of this Agreement.

     Section 7.04. Cooperation. After the Closing, each of Buyer and Seller will cooperate with the other, and cause its directors, officers and employees to cooperate with the other, in furnishing information, evidence, testimony, and other assistance as may be reasonably requested by the other party in connection with: (i) any pending or Threatened Proceeding resulting or arising from the transactions contemplated by this Agreement or any fact, situation, circumstance, status, condition, activity, practice, failure to act or transaction relating to Seller or the Business, the Assumed Obligations, the Excluded Liabilities or the Purchased Assets or (ii) compliance by the other Party with any Legal Requirements pertaining to or the Assumed Obligations, the Purchased Assets, or the Business. Subject to Article IX hereof, the party requesting such assistance will pay or reimburse the other party for all reasonable out of pocket expenses incurred by the party providing such assistance in connection therewith, including, without limitation, all travel, lodging, and meal expenses.

     Section 7.05. Administration of Accounts.

           (a) All payments and reimbursements by any third party in the name of or to Seller in connection with or arising out of the Purchased Assets, the Business or the Assumed Obligations, to the extent received after the Closing Time shall be held by Seller in trust for the benefit of the Buyer and, immediately upon receipt by Seller of any such payment or reimbursement, Seller shall pay over or cause to be paid over to Buyer the amount of such payment or reimbursement without right of set-off.

           (b) All payments and reimbursements by any third party in the name of or to Buyer in connection with or arising out of the Excluded Assets or the Excluded Liabilities, to the extent received after the Closing Time shall be held by Buyer in trust for the benefit of Seller and, immediately upon receipt by Buyer of any such payment or reimbursement, Buyer shall pay over to Seller the amount of such payment or reimbursement without right of set-off.

     Section 7.06. Access to Former Business Records. After the Closing, Seller shall deliver immediately to Buyer any and all books and records which remain in their possession which are included in the Purchased Assets. After the Closing Time, Buyer will afford duly authorized representatives of Seller reasonable access to financial, tax and other books and records retained by it which constitute part of the Purchased Assets for any reasonable purpose, including, without limitation, litigation, financial and tax

reporting purposes, and will permit such representatives, at Seller’s expense, to make abstracts from, or to take copies of any of such books and records, or to obtain temporary possession thereof as may be reasonably required by Seller. After the Closing Time, Seller will afford duly authorized representatives of Buyer reasonable access to financial, tax and other books and records retained by it which pertain to the Purchased Assets and the Assumed Obligations, if any, which are not included within the Purchased Assets for any reasonable purpose including, without limitation, litigation and financial and tax reporting, and will permit such representatives, at Buyer’s expense, to make abstracts from, or to take copies of any of such books and records, or to obtain temporary possession thereof as may be reasonably required by Buyer. Each party shall preserve and keep such books and records for a period of seven (7) years following the Closing Date, or for any longer period that may be required by any Governmental Authority or ongoing Proceeding; provided that any Party may dispose of any such books and records retained by it at any time provided that prior to any such disposition within the seven (7) years after the Closing Time a Party desiring to dispose of any such books and records shall give advance notice to the other Party and afford the other Party the opportunity to take possession or copy such books and records as the other Party may select.

     Section 7.07. Product Warranty Claims and Services. If a customer of the Business makes a claim against Buyer for the repair, return or replacement of, or the refund of all or any portion of the purchase price of, any product sold by Seller, in its conduct of the Business prior to the Closing Time, then Buyer shall, following notice to Seller, at its option, either: (a) replace such product and pay packing, shipping and other similar costs incident to such product replacement or (b) pay to such customer or credit such customer’s account an amount up to the purchase price of such product together with packing, shipping and other similar costs incident to such purchase. If the sum of the losses incurred or amounts paid by Buyer exceeds Twenty-Five Thousand Dollars ($25,000) in the aggregate, then Seller shall, promptly upon demand, reimburse Buyer for such amounts incurred in excess of the $25,000 threshold. Buyer shall maintain in the ordinary course, records which describe the nature of each such customer claim and Buyer’s response to such claim and shall make such records available to Seller upon Seller’s request. Any customer claim to the extent seeking any remedy other than product repair, return or replacement or product purchase price refund, which for purposes of this Agreement shall include any liabilities or obligations for consequential, incidental and liquidated damages as well as lost profits and other monetary amounts due to customers of Seller whether imposed by contract, law or otherwise, for goods and equipment shipped prior to the Closing Time, shall be Excluded Liabilities and from and after the Closing Time, Buyer shall not have any liability whatsoever therefor. For the avoidance of doubt, Section 9.05(b) and (c) shall not apply to this Section 7.07.

     Section 7.08. Name Change. CTI shall change its corporate name to not include the word “Cross.”

     Section 7.09. Website and Emails. After Closing, the Seller shall replace the link to the Business’ current website contained on HEI’s website with a reference to a new Business website when created by Buyer, and shall maintain such reference for a period of one hundred eighty (180) days following Closing. After Closing, the Seller shall use commercially reasonable efforts to cause emails sent to the email addresses of former employees of the Business to be forwarded to the new email addresses of such employees of the Buyer as and when provided by Buyer, or to be replied to with a notice of such new email addresses, for a period of one hundred eighty (180) days following Closing.

After Closing and for a period of one hundred eighty (180) days following Closing, the Seller shall set up and maintain a telephone message on the Business telephone numbers which will refer callers to the new telephone numbers of the Business after Closing as provided by Buyer, and shall instruct the Seller’s receptionists to provide callers who want to contact the Business after Closing with the new telephone numbers of the Business after Closing as provided by Buyer.

provided, however, that the representations and warranties contained in Article VI hereof shall expire at 11:59 p.m. (Central Standard Time) one (1) year after the Closing Time unless Buyer has asserted a claim with respect to any such matters prior to such one (1) year expiration, except for the representations and warranties set forth in Sections 6.01, 6.02 and 6.03, which shall expire upon the expiration of the applicable statue of limitations, and the representations and warranties set forth in Sections 6.14 and 6.20, which shall not expire. Notwithstanding the foregoing, the expiration of any such representation or warranty shall not in any manner limit Buyer’s or any Buyer Entities’ rights under this Article IX with respect to Excluded Liabilities.

     Section 9.02. Indemnification by Seller. HEI and CTI shall, jointly and severally, defend Buyer and any Affiliate of Buyer (the “Buyer Entities”) against any and all Proceedings arising from, and shall indemnify and hold harmless the Buyer Entities for, and will pay to the Buyer Entities the amount of any Damages, incurred or suffered, directly or indirectly, by the Buyer Entities as a result of, relating to or arising out of:

           (a) any inaccuracy or misrepresentation in or breach of any representation or warranty made by Seller in this Agreement or the Schedules;

           (b) any failure to perform or breach of any covenant or agreement made by Seller in this Agreement; and

           (c) any Excluded Liabilities.

     Section 9.03. Indemnification by Buyer. Except for Seller’s obligations under Section 9.02 hereof, Buyer shall defend Seller and any Affiliate of Seller (the “Seller Entities”) against any and all Proceedings arising from, and shall indemnify and hold harmless the Seller Entities for, and will pay to the Seller Entities the amount of any Damages, incurred or suffered, directly or indirectly, by a Seller Entity, as a result of, relating to or arising out of:

           (a) any inaccuracy or misrepresentation in or breach of any representation or warranty made by Buyer in this Agreement or the Schedules;

           (b) any failure to perform or breach of any covenant or agreement made by Buyer in this Agreement; and

           (c) any Assumed Obligations.

     Buyer’s obligation shall be guaranteed by Smartrac, in the form set forth on Exhibit G hereto.

     Section 9.04. Third Party Claim Procedures. If a Buyer Entity or Seller Entity receives notice of the assertion of any Third Party Claim in respect of which such party may have a claim under Section 9.02 or 9.03 hereof, then the following shall apply:

           (a) The party against whom any such Third Party Claim is made (the “Indemnified Party”), shall promptly provide written notice (an “Indemnity Notice”) of such Third Party Claim to the other party (the “Indemnifying Party”). Such Indemnity Notice shall describe in reasonable detail the nature of the Third Party Claim and the basis for its claim under Section 9.02 or 9.03 hereof; provided that the failure to provide such notice shall not affect a party’s rights under Section 9.02 or 9.03 hereof except to the extent the other party is materially prejudiced by the failure to give such notice. An Indemnity Notice by a party shall not preclude such party from giving subsequent

Indemnity Notices with respect to other claims, whether arising before or after the claims for which prior notice is given.

           (b) Upon receipt of an Indemnity Notice, the Indemnifying Party shall have the right to promptly assume, at its sole cost and expense, the defense or settlement of such Third Party Claim with counsel reasonably acceptable to the Indemnified Party, provided that the Indemnifying Party has irrevocably agreed in writing to indemnify and hold harmless the Indemnified Party in respect of all Damages arising or resulting from such Third Party Claim. The Indemnifying Party shall give prompt written notice to the Indemnified Party of its intent to enter into such agreement and assume the defense of any such Third Party Claim and shall conduct the defense and/or settlement of such Third Party Claim diligently and in good faith.

           (c) Notwithstanding Section 9.04(b) hereof, if (i) an Indemnified Party is obligated to permit an insurer or other Third Party having liability therefore to assume the defense of a Third Party Claim; or (ii) an Indemnified Party determines in good faith that there is a reasonable possibility that a Third Party Claim may materially and adversely affect it or its assets or business other than as a result of the payment of monetary damages; or (iii) the Indemnifying Party and Indemnified Party are both named parties in a Third Party Claim and there are legal defenses available to the Indemnified Party which are different from or in addition to those available to the Indemnifying Party; or (iv) if the Indemnifying Party fails, after reasonable notice from the Indemnified Party, to diligently and in good faith defend such Third Party Claim; or (v) after being requested to do so by the Indemnified Party, the Indemnifying Party fails to provide the Indemnified Party with reasonable assurance of its financial ability to satisfy its defense and indemnification obligations hereunder, then, at the option of the Indemnified Party, the Indemnifying Party shall not have the right to assume the defense of such Third Party Claim and the Indemnified Party may, by notice to the Indemnifying Party, reassume the defense of any such Third Party Claim previously assumed by the Indemnifying Party. No retention or re-assumption of any such defense by the Indemnified Party shall prejudice any rights of the Indemnified Party under Section 9.02 or 9.03 hereof.

           (d) If the Indemnifying Party does not give notice and assumes the defense of such Third Party Claim in accordance with Section 9.04(b) hereof or is not entitled to assume or retain the defense thereof, the Indemnified Party shall have full and exclusive authority to defend and/or settle any such Third Party Claim for the account of and at the sole risk, cost and expense of the Indemnifying Party. If the Indemnified Party undertakes the defense and/or settlement of any such Third Party Claim it shall do so diligently and in good faith and the Indemnifying Party shall from time to time upon the request of the Indemnified Party reimburse the Indemnified Party for the costs incurred by the Indemnified Party in defending and/or settling such Third Party Claim. The Indemnifying Party shall be bound by settlement entered into by the Indemnified Party to the extent that such settlement is commercially reasonable measured in the context of the matter settled and by any judgment resulting from such Third Party Claim. If the Indemnifying Party had the right to assume the defense and settlement of such Third Party Claim and did not do so then, in any dispute between the Indemnifying Party and Indemnified Party regarding the defense or settlement of such Third Party Claim, the Indemnifying Party shall have the burden to prove that the Indemnified Party did not defend such Third Party Claim diligently and in good faith and/or settle such claim in a commercially reasonable manner.

           (e) The Parties agree that the Indemnified Party may join the Indemnifying Party in any legal proceeding brought by the third party asserting such

Third Party Claim as to which any right under Section 9.02 or 9.03 hereof would or might apply, for the purpose of enforcing any such right.

           (f) The Indemnifying Party shall not admit any liability, settle, compromise, pay or discharge, without the consent of the Indemnified Party, any Third Party Claim being defended by it unless with respect to any settlement (i) the Indemnified Party is not obligated to perform or to refrain from performing any act under such settlement and there is no encumbrance on any assets of the Indemnified Party; (ii) there is no finding or admission of any violation of any Legal Requirement, violation of the rights of any Person by the Indemnified Party or any other liability of the Indemnified Party to any Person; and (iii) the Indemnified Party receives, as a part of such settlement, a complete release, in form and substance reasonably satisfactory to Indemnified Party.

           (g) The party controlling the defense of a Third Party Claim shall keep the other party reasonably informed at all stages of the defense and/or settlement of such Third Party Claim. The party not controlling the defense of any such Third Party Claim shall have the right, at its sole cost and expense, to participate in, but not control, the defense of any such Third Party Claim. Each party shall reasonably cooperate with the other in the defense and/or settlement of any such Third Party Claim, including, without limitation, by furnishing such records, information and testimony and attending such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith, but the Indemnifying Party will reimburse the Indemnified Party for any fees or expenses incurred by it in so cooperating or acting at the request of the Indemnifying Party.

     Section 9.05. Limitations. The rights to recover Damages under Sections 9.02 and 9.03 shall be subject to the following:

           (a) Each party acknowledges and agrees that the obligation of the other to indemnify pursuant to Sections 9.02(a) and 9.02(b) or 9.03(a) and 9.03(b), as the case may be, shall be limited to One Million Five Hundred Thousand Dollars ($1,500,000).

           (b) No party will be entitled to indemnification from the other pursuant to Section 9.02 or 9.03, as the case may be, until such time as the total amount of all Damages (including the Damages arising from such breach and all other Damage arising from any other breaches of any representations or warranties), exceeds One Hundred and Twenty-Five Thousand Dollars ($125,000) in the aggregate (the “Basket”) and then only for the amount by which such Damages exceed the Basket.

           (c) Notwithstanding anything in this Agreement to the contrary, no liability, obligation, contract or other fact or circumstance will constitute a breach of any representation or warranty of Seller or entitle Buyer to indemnification hereunder:

                 (i) if the liability, obligation, contract or other fact or circumstance is disclosed in the disclosure Schedules; or

                 (ii) to the extent that the liability, obligation, contract or other fact or circumstance was provided for, or specifically referred to, in the Financial Statements.

           (d) In the absence of fraud and remedies under Section 7.02, the indemnification provisions set forth in this Article IX will provide the exclusive remedy for Buyer for breach of any covenant, agreement, representation or warranty of Seller set

forth in this Agreement or any other agreement ancillary hereto executed pursuant to this Agreement.

           (e) Any remedy of any Buyer Entities or Seller Entities hereunder shall be determined without regard to whether or not the transactions provided for in this Agreement prove generally to be favorable to a Party and without regard to whether or not the facts and circumstances covered by any representation, warranty or covenant prove to be more favorable to a Party than so represented, warranted or covenanted.

           (f) No Buyer Entity or Seller Entity shall be entitled to recover Damages under Sections 9.02(a) or 9.03(a), as the case may be, unless it shall make its claim therefor on or prior to the date on which the relevant representation or warranty shall expire pursuant to Section 9.01 and if, prior to the expiration of the representation or warranty, a claim is made then the Buyer Entity or Seller Entity making such claim shall not be precluded from pursuing such claim or otherwise in any way prejudiced in respect of such claim by reason of the expiration of such representation or warranty.

     Section 9.06. Covenant to Maintain Insurance. Seller shall maintain in effect, for a period of at least one (1) year following the Closing, one or more policies of insurance to insure against damages to person or property which are included in the Excluded Liabilities pursuant to this Agreement, but only to the extent such risks are currently insured against, provided, however, such insurance shall (i) be primary insurance and exclusive of any insurance of Buyer or its Affiliates; (ii) not require contribution by Buyer or its Affiliates to the payment of any premiums; (iii) name Buyer and its Affiliates as additional insured and waive subrogation against Buyer or its Affiliates and their insurers.

     Section 9.07. Specific Performance. The Parties acknowledge and agree that the other Parties would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached. Accordingly, each of the Parties agree that the other Parties shall be entitled to an injunction or injunctions to prevent breaches of the provisions of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof in any action instituted in any court of the United States or any state thereof having jurisdiction over the Parties and the matter, in addition to any other remedy to which they may be entitled, at law or in equity.

     Section 9.08. Attorney Fees.

           (a) If any Party to this Agreement shall bring any action for any relief against any other Party, declaratory or otherwise, arising out of this Agreement, the losing Party or Parties shall pay to the prevailing Party or Parties a reasonable sum for attorneys’ fees (at a reasonable hourly rate) incurred in bringing or defending such action and/or enforcing any judgment granted therein, all of which shall be deemed to have accrued upon the commencement of such action and shall be paid whether or not such action is prosecuted to judgment. To so recover, it shall not be necessary that the prevailing Party or Parties prevail in each and every one of its or their claims. Rather, the award of attorneys’ fees shall, in the court’s discretion, reflect the degree to which the prevailing Party or Parties has or have prevailed in some of its or their claims. Any judgment or order entered in such action shall contain a specific provision providing for the recovery of attorneys’ fees and costs incurred (at a reasonable hourly rate) in enforcing such judgment. For the purposes of this Section 9.09(a), attorneys’ fees shall include, without limitation, fees incurred in the following: (i) post judgment motions;

(ii) contempt proceedings; (iii) garnishment, levy, and debtor and third party examination; (iv) discovery; and (v) bankruptcy litigation.

           (b) Attorneys’ fees (at a reasonable hourly rate) incurred by any Party in enforcing any judgment on any action brought to resolve any controversy arising under this Agreement, to enforce any of its terms or for the breach of this Agreement, shall be recoverable by the prevailing Party or Parties. Such right to post judgment attorneys’ fees shall be separate and distinct from the right to recover attorneys’ fees pursuant to Section 9.09(a) hereof. The provisions of this Section 9.09(b) shall be severable from all other provisions of this Agreement, shall survive any judgment and shall not be deemed merged into any judgment.
