In case at any time after the Closing any further action is necessary or desirable to carry out the purposes of this Agreement, each of the parties will take such further action (including the execution and delivery of such further instruments and documents) as any other party reasonably may request, all at the sole cost and expense of the requesting party (unless the requesting party is entitled to indemnification therefor under Article VII below). The Seller acknowledges and agrees that from and after the Closing the Buyer will be entitled to possession of all documents, books, records (including Tax records), agreements, and financial data of any sort relating to the Company.

     6.2 Litigation Support. In the event and for so long as the Company is actively contesting or defending against any action, suit, proceeding, hearing, investigation, charge, complaint, claim or demand in connection with any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act or transaction on or prior to the Closing Date involving the Company, Molfetta will (i) cooperate with the Company, the Buyer and their respective counsel in the contest or defense, and (ii) provide such testimony and access to her books and records as shall be necessary in connection with the contest or defense, all at the sole cost and expense of the Company (unless the Buyer is entitled to indemnification therefor under Article VII below).

     6.4 Confidentiality. The Seller will treat and hold as such all of the Confidential Information, refrain from using any of the Confidential Information except in connection with this Agreement or its employment by the Company. In the event that the Seller is requested or required (by oral question or request for information or documents in any legal proceeding, interrogatory, subpoena, civil investigative demand or similar process) to disclose any Confidential Information, the Seller will notify the Buyer promptly of the request or requirement so that the Buyer may seek an appropriate protective order or waive compliance with the provisions of this Section 6.4. If, in the absence of a protective order or the receipt of a waiver hereunder, the Seller is, on the advice of counsel, compelled to disclose any Confidential Information to any tribunal or else stand liable for contempt, the Seller may disclose the Confidential Information to the tribunal; provided, however, that the Seller shall use reasonable efforts to obtain, at the reasonable request of the Buyer, an order or other assurance that confidential treatment will be accorded to such portion of the Confidential Information required to be disclosed as the Buyer shall designate. The foregoing provisions shall not apply to any Confidential Information which is generally available to the public immediately prior to the time of disclosure. The obligations of the Seller under the provisions of this Section 6.4 shall survive for a period of three (3) years after the Closing Date.

     6.5 Covenant Not to Compete.

     (a)(i) During the Noncompete Term, neither Molfetta nor the Trust shall carry on or engage or participate in any business substantially the same as or in competition with the Business.

     (ii) The prohibition appearing in subsection (a)(i) above shall extend throughout the State of Nevada.

     (iii) The phrase “carry on or engage or participate in any business substantially the same as or in competition with the Business” shall include, without limitation, doing any of the following — listed acts with the intent of profit, production of income or any type of remuneration in whatever form whether direct or indirect to Molfetta or the Trust or a member of Molfetta’s immediate family: (A) carrying on or engaging in any such business as the principal, or on her or its own account, or solely or jointly with others as a director, officer, agent, employee, independent contractor, manager, consultant or partner (general or limited), shareholder or holder of an equity security (except that Molfetta and/or the Trust may own up to 3% of the equity securities or securities convertible into equity securities of any corporation or other entity the securities of which are traded on a national stock exchange or listed on the National Association of Securities Dealers Automated Quotation System and may make personal real estate related investments) or otherwise; (B) lending credit or money for the purpose of establishing or operating any such business; (C) giving advice to any other Person engaging in any such business; (D) lending or consenting to the use of her or its name or reputation to be used in any such business; or (E) allowing her or its skill, knowledge or experience to be used in any such business.

     (iv) “Noncompete Term” shall mean that period commencing with the Closing Date and ending three (3) years later; provided, however, that the duration of the Noncompete Term shall be extended by and for the duration of any period during which either Molfetta or the Trust is in violation of this Section 6.5(a).

     (b) During the two (2) year period immediately following the Closing Date, neither Molfetta nor the Trust shall, either on its own account or directly or indirectly in conjunction with or on behalf of any Person, call upon or solicit any employee of the Company or the Buyer for the purpose or with the intent of enticing that employee from or out of the employ of the Company or the Buyer, as the case may be, for any reason whatsoever.

     (c) It is the desired intent of the parties that the provisions of this Section 6.5 be enforced to the fullest extent permissible under the laws and public policies of Nevada and any other applicable jurisdiction. Accordingly, to the extent that any covenant hereunder or a portion thereof shall be adjudicated to be invalid or unenforceable, this Section 6.5 shall be reformed such that the restrictions imposed upon Molfetta and the Trust are no greater than would otherwise be permissible under applicable law.

Moreover, each provision of this Section 6.5 is intended to be severable; and in the event that any one or more of the provisions contained in this Section 6.5 shall for any reason be adjudicated to be invalid or enforceable and incapable of reformation in accordance with the terms of the preceding sentence, the same shall not affect the validity or enforceability of any other provision of this Section 6.5, but this Section 6.5 shall be construed as if such invalid or unenforceable (and nonreformable) provision had not been contained herein.

     (d) Molfetta and the Trust hereby acknowledge and agree that, in the event of a prospective or actual breach of any of the provisions of this Section 6.5 by it, damages would not be an adequate remedy to compensate the Company and the Buyer for the loss of goodwill and other harm to the business of the Company. In the event of a threatened or actual breach of any of the provisions of this Section 6.5 by either Molfetta or the Trust, the parties agree that the Buyer or the Company shall be entitled, if it so elects, to a temporary restraining order and to temporary and permanent injunctive relief to prevent or terminate such anticipated or actual breach, in each case without the necessity of a bond. In addition, the Buyer and the Company shall each be entitled to such damages as it can show it sustained by reason of such threatened or actual breach. Nothing in this Section 6.5 shall be construed to limit in any way the remedies of the Buyer or the Company for a breach of the covenants contained in this Section 6.5. The Buyer and the Company shall have the right to inform any person that they reasonably believe to be, or to be contemplating, participating with either Molfetta or the Trust or receiving from Molfetta or the Trust assistance in violation of the terms of this Section 6.5 and the rights of the Buyer and the Company hereunder, that participation by any such Person with Molfetta and/or the Trust in activities in violation of this Section 6.5 may give rise to claims by the Buyer and/or the Company against such Person.

     6.6 Employer Identification Number. The Company’s employer identification number is ###-###-#### (the “Existing EIN”). After the Closing Date, the Buyer will not report any payroll, for federal or state employment tax purposes, using the Existing EIN. Buyer acknowledges and agrees that the employees of the Company shall be treated as employees of the Buyer beginning on the day following the Closing Date and thereafter for all purposes, including payroll and employment tax purposes. In addition, the Company shall use commercially reasonable efforts to begin using Buyer’s employer identification number with respect to each of the Managed Care Contracts to which the Company is a party on the Closing Date within nine (9) months after the Closing. Notwithstanding anything to the contrary in the preceding sentence, the Company shall not be obligated to use or attempt to use Buyer’s employer identification number with respect to any such Managed Care Contract if Buyer has reasonable grounds to believe that such use, or notice of Buyer’s employer identification number would have a material adverse effect upon the Company’s ability to maintain the existing terms of such Managed Care Contract. To the extent that any income earned after the Closing Date under a Managed Care Contract is included on a Form 1099 issued using the Existing EIN, Buyer shall prepare and file with the Internal Revenue Service a nominee Form 1099 which reattributes all such post-Closing income to Buyer’s employer identification number. Upon receipt of a request from Molfetta on or after March 1 of any calendar year, Buyer shall provide Molfetta with copies of all 1099’s it received for the previous calendar year which referenced the Existing EIN, and all nominee Forms 1099 filed by Buyer pursuant to the preceding sentence. In

addition, notwithstanding anything to the contrary herein, if either Buyer or one of its Affiliates ceases to own at least 51% of the outstanding equity interests of the Company, the Company shall promptly cease using the Existing EIN for any purpose.

     6.7 Continued Service of Molfetta. Commencing on the Closing Date and continuing for sixty (60) days thereafter, Molfetta shall personally provide up to forty (40) hours per week of consulting services to the Company as requested by the Company; thereafter and until the first anniversary of the Closing Date, Molfetta shall personally provide up to five (5) hours per week of consulting services to the Company, as requested by the Company.

     7.3 Indemnification by Buyer. Subject to the terms and conditions set forth herein, the Buyer shall indemnify and hold harmless Molfetta and the Trust and their respective agents and Affiliates (collectively, the “Seller Indemnitees”) in respect of any Damages asserted against or incurred by any Seller Indemnitee as a result of, in connection with or arising out of:

     7.4 Third Party Indemnification. The obligations of Molfetta and the Trust to indemnify the Buyer Indemnitee under Section 7.2 and the obligations of the Buyer to indemnify the Seller Indemnitees under Section 7.3 hereof, in each case resulting from the assertion of liability by a third party (each, as the case may be, a “Claim”), shall be further subject to the following terms and conditions:

Failure to give prompt notice of a Claim hereunder shall not affect the indemnifying party’s obligations under this Section 7.4, except to the extent the indemnifying party is materially prejudiced by such failure to give prompt notice. If the indemnifying party, within thirty (30) days after notice of any such Claim, or such shorter period as is reasonably required, fails to assume the defense of such Claim, the Buyer Indemnitee or the Seller Indemnitee, as the case may be (each, an “Indemnitee”), against whom such Claim has been made shall have the right, but shall not be obligated, to undertake the defense, compromise or settlement of such Claim on behalf and for the account and risk, and at the expense, of the indemnifying party.

     (b) Anything in this Section 7.4 to the contrary notwithstanding, the indemnifying party shall not enter into any settlement or compromise of any action, suit or proceeding or consent to the entry of any judgment (A) which does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnitee of a written release from all liability in respect of such action, suit or proceeding, or (B) for other than monetary damages without the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld.

     7.5 Buyer’s Right of Setoff. The parties hereby agree that any Damages suffered by the Buyer (or any other Buyer Indemnitee) for which the Buyer Indemnitees are entitled to be indemnified by Molfetta and the Trust pursuant to Section 7.2 shall be subject to setoff against the Post-Closing Payment, provided that Buyer shall be deemed to have waived its right of setoff with respect to any particular Damages suffered by the Buyer (or any other Buyer Indemnitee) unless Buyer delivers written notice (the “Notice”) of such Damages to Seller within thirty (30) days after Buyer’s discovery of such Damages. Such notice shall include a description in reasonable detail of the basis for the indemnification claim, a good-faith estimate of the total amount of Damages incurred or to be incurred by the Buyer Indemnitee, the name of the claimant, a copy of the demand or other evidence of the claim and any other relevant

information relating to the claim. Within fifteen (15) days of Seller’s receipt of the Notice, Seller shall in a writing delivered to Buyer either accept or dispute the claim disclosed in the Notice.

Claims accepted by Seller shall be subject to Buyer’s right of setoff against the Post-Closing Payment. Claims disputed by Seller shall not be subject to Buyer’s right of setoff against the Post-Closing Payment unless and until Seller’s liability for the disputed claim is determined either by the mutual agreement of Buyer and Seller or by a neutral, third-party arbitrator; provided, however, that, in the event Seller disputes any such claim, the amount of Damages alleged in good faith by Buyer to be subject to Buyer’s right of setoff shall be held in escrow by a third party selected by the parties until Seller’s liability for the disputed claim is determined as described above. In the event the Buyer asserts its right of setoff hereunder, no more than the amount of Damages alleged in good faith to be subject to such right of setoff shall be retained by the Buyer and the remainder of the Post-Closing Payment (the “Post-Setoff Amount”) shall be disbursed in accordance with Section 2.2(iii) on the first anniversary of the Closing Date. In the event the Buyer fails to disburse the Post-Setoff Amount to the Trust on the first anniversary of the Closing Date, the Seller may pursue any and all remedies available to Seller at law, in equity or otherwise.
