ARTICLE V

CONFIDENTIALITY AND NONSOLICITATION

5.1 Confidentiality; Proprietary Information. In the course of the relationship created pursuant to this Agreement, Group will have access to certain methods, trade secrets, processes, ideas, systems, procedures, inventions, discoveries, concepts, software in various stages of development, designs, drawings, specifications, models, data, documents, diagrams, flow charts, research, economic and financial analysis, developments, procedures, know-how, policy manuals, form contracts, marketing and other techniques, plans, materials, forms, copyrightable materials and trade information (all of which is referred to in this Agreement as “Proprietary Information”) regarding the operations of Service Company and/or of its Affiliates (collectively, the “Protected Parties”). Group shall maintain all such Proprietary Information in strict secrecy and shall neither use for itself or any third parties nor divulge such information to any third parties, except as may be necessary for the discharge of their obligations under this Agreement or otherwise consented to in writing by Service Company. Group shall take all necessary and proper precautions against disclosure of any Proprietary Information to unauthorized Persons by any of its employees or agents. Group and all employees and agents of Group who will have access to all or any part of the Proprietary Information may be required to execute an agreement, at the request of Service Company, valid under the law of the jurisdiction in which such agreement is executed, and in a form acceptable to Service Company and its counsel, committing themselves to maintain the Proprietary Information in strict confidence and not to disclose it to any unauthorized Person. Upon termination of this Agreement for any reason, Group and each of its Providers shall cease all use of any of the Proprietary Information and, at the request of Service Company, shall execute such documents as may be necessary to evidence Group’s abandonment of any claim thereto. The parties recognize that a breach of this Section cannot be adequately compensated in money damages and therefore agree that injunctive relief shall be available to the Protected Parties as their respective interests may appear.

The obligations of Group under this Section shall apply as long as Group or any of Providers are in possession of Proprietary Information; provided, however, that the obligations of Group under this Section shall not apply to information: (i) that is a matter of public knowledge on or becomes a matter of public knowledge after the Effective Date of this Agreement, other than by breach of this Agreement or as a breach of the confidentiality terms of any other agreement between a third party and Group, Service Company and/or its Affiliates; or (ii) that was lawfully obtained by Group on a nonconfidential basis other than in the course of performance under this Agreement and from some Person other than Service Company or its Affiliates or from some Person other than one employed or engaged by Service Company or its Affiliates, which Person has no obligation of confidentiality to Service Company or its Affiliates.

5.2 Covenant Not to Solicit. For three years following termination of this Agreement, Group shall not:

(a) directly or indirectly solicit, recruit or induce any party to solicit or recruit any Person who is an employee of, or who has entered into an independent contractor arrangement with, Service Company or any Affiliate of Service Company;

(b) directly or indirectly, whether for itself or for any other Person or entity, call upon, solicit, divert or take away, or attempt to solicit, call upon, divert or take away any of Service Company’s customers, business or clients; or

(c) directly or indirectly solicit, or induce any party to solicit, any of Service Company’s contractors or the contractors of any Affiliate of Service Company, to enter into the same or a similar type of contract with any other party.

5.3 Enforcement. Service Company and Group acknowledge and agree that since a remedy at law for any breach or attempted breach of the provisions of this Article V would be inadequate, either party shall be entitled to specific performance and injunctive or other equitable relief in case of any such breach or attempted breach, in addition to whatever other remedies may exist by law. All parties hereto also waive any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other equitable relief.

ARTICLE VI

FINANCIAL ARRANGEMENTS

6.1 Reimbursement of Clinic Costs. Group shall reimburse Service Company for all Clinic Costs incurred by Service Company.

6.2 Payment of Services Fee. Group agrees to pay Service Company the Services Fee in consideration of Service Company’s provision of the Business Support Services.

6.3 Payments. Amounts to be paid or reimbursed to Service Company pursuant to this Article VI shall be calculated by Service Company pursuant to the accrual basis of accounting and shall accrue and become payable daily, with actual payments during the term of this Agreement to be made from time to time out of Group’s available cash.

6.4 Adjustments to Services Fee.

(a) Annual Increase. Service Company shall have the right to increase the Services Fee at any time, and any such increases shall be immediately effective; provided, however, that, in any fiscal year, Service Company’s aggregate total increases in the Services Fee for such fiscal year may not exceed five percent of the Services Fee then in effect on the first day of such fiscal year. However, failure by the Service Company to increase the Services Fee by the full five percent in any fiscal year shall not operate as a waiver of Service Company’s right to adjust and correct retroactively the full amount of the five percent increase due in all subsequent fiscal years.

(b) Adjustments. If, in any period, Group does not have sufficient funds to pay the Service Fee, Service Company, in its sole discretion, may defer the amount of any unpaid Service Fee to future periods. Any such deferred amounts shall accumulate and Service Company, in its sole

discretion, may charge such deferred amounts to the Group in any future period selected by Service Company. In addition, Service Company shall monitor and reconcile the Service Fees paid (and deferred, if any) on an annual basis and any overpayment of the Service Fee shall, at the election of Service Company, be refunded by Service Company to Group or applied as payment against any future Service Fee obligations of Group.

(c) Periodic Review. The Services Fee shall be reviewed from time to time to ensure the Service Company is fairly and reasonably compensated for its provision of the Business Support Services, and to ensure that Service Company does not receive compensation other than that which is fair and reasonable for its provision of the Business Support Services. Any changes to the Services Fee, other than those described above in Section 6.4 (a) and (b), shall be subject to the sole and nonreviewable discretion of the Chief Financial Officer of Service Company.

6.5 Reasonable Value. Reimbursement by Group of the Clinic Costs and payment by Group of the Services Fee is acknowledged as the parties’ negotiated agreement as to the reasonable fair market value of the Business Support Services furnished by Service Company pursuant to this Agreement, considering the nature and volume of the services required and the risks assumed by Service Company.

6.6 Patient Referrals and Payments. Service Company and Group agree that the benefits to Group hereunder do not require, are not payment for and are in no way contingent upon referral, admission or any other arrangement for the provision of any item or service offered by Service Company. Further, Service Company and Group agree that the payment of monies hereunder in no way represents the division, sharing, splitting or other allocation of fees for Dental Services between Group and Service Company.

6.7 Grant of Security Interest. As security for Group’s reimbursement of the Clinic Costs and for Group’s payment of the Services Fee, Group hereby grants to Service Company a security interest in all of Group’s right, title and interest in Group’s accounts, accounts receivable, contract rights, deposits, deposit accounts, inventory, equipment and general intangibles relating to the Practice, wherever located and whether now existing or owned or hereafter acquired (collectively, the “Collateral”); provided, however, that the Collateral shall not include any patient records (whether confidential or otherwise) or other property of Group the disclosure, transfer, assignment, pledge or encumbrance of which is prohibited by, or is otherwise contrary to, applicable law. In addition, Group authorizes Service Company to prepare and file any and all documents Service Company deems appropriate to perfect its security interest hereunder, and Group agrees to cooperate with Service Company and execute all documents requested by Service Company to enable Service Company to perfect its security interest hereunder.

ARTICLE VII
