ARTICLE VII

RESTRICTIVE COVENANTS

7.1 Non-Competition. Seller, David and Peter hereby agree that as a material inducement to Buyer to enter into this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Seller, David and Peter covenant and agree that it and they, and each of Seller’s Affiliates, and David’s and Peter’s Affiliates and immediate family members, shall not, for the period from the date hereof until five (5) years following the Closing Date (the “Restricted Period”), directly or indirectly, on its own behalf or in the service of or on the behalf of others, as a director, trustee, owner (except as the owner of less than two percent (2%) of the outstanding stock of a publicly held corporation), employee, consultant, advisor, independent contractor or in any other capacity, engage in the business of operating a pharmacy that in any way services or treats, or markets or sells AIDS/HIV products to, AIDS/HIV patients, within seventy five (75) miles of Seller’s present pharmacy in San Diego, California (the “Restricted Territory”).

Seller, David and Peter further agree that, during the Restricted Period and within the Restricted Territory, Seller, David and Peter will not, directly or indirectly; (i) induce any former customer of or referrer of customers to Seller or customer of or referrer of customers to Buyer to patronize any Person who competes with Buyer; (ii) request or advise any former customer of or referrer of customers to Seller or customer of or referrer of customers to Buyer to withdraw, curtail or cancel such Person’s business with Buyer; (iii) enter into any contract, the purpose or result of which would benefit such Seller if any former customer of or referrer of customers to Seller or customer of or referrer of customers to Buyer were to withdraw, curtail, or cancel such customer’s or referrer’s business with Buyer; or (iv) disclose to any other Person the names or addresses of any former customer of or referrers of customers to Seller or customer of or referrers of customers to Buyer, either individually or collectively.

7.3 Acknowledgements. If the provisions of this Article VII are violated, in whole or in part, Buyer shall be entitled, upon application to any court of proper jurisdiction, to a temporary restraining order or preliminary injunction to restrain and enjoin Seller, David and Peter, and their respective Affiliates, from such violation without prejudice as to any other remedies Buyer may have at law or in equity. In the event of a violation, Seller, David and Peter agree that it would be virtually impossible for Buyer to calculate its monetary damages and that Buyer would be irreparably harmed. If Buyer seeks such temporary restraining order or preliminary injunction, Buyer shall not be required to post any bond with respect thereto, or, if a bond is required, it may be posted without surety thereon. If any restriction contained in this Article VII is held by any court to be unenforceable, or unreasonable, as to time, geographic area or business limitation, Buyer, Seller, David and Peter agree that such provisions shall be and are hereby reformed to the maximum time, geographic area or business limitation permitted by applicable laws. The parties further agree that the remaining restrictions contained in this Article VII shall be severable and shall remain in effect and shall be enforceable independently of each other. Seller, David and Peter specifically acknowledge, represent and warrant that the covenants set forth in this Article VII are reasonable and necessary to protect the legitimate interests of Buyer, and that Buyer would not have entered into this Agreement or paid the Purchase Price in the absence of such covenants.

8.4 Indemnification Procedures.

(a) The rights and obligations of each party claiming a right to indemnification hereunder (“Indemnitee”) from the other party (“Indemnitor”) shall be governed by the following rules:

(i) The Indemnitee shall give prompt written notice to the Indemnitor of any state of facts which Indemnitee determines will give rise to a claim by the Indemnitee against the Indemnitor based on the indemnity agreements contained herein, stating the nature and basis of said claims and the amount thereof, to the extent known. No failure to give such notice shall affect the indemnification obligations of Indemnitor hereunder, except to the extent such failure materially prejudices such Indemnitor’s ability successfully to defend the matter giving rise to the indemnification claim.

(ii) In the event any action, suit or proceeding is brought against the Indemnitee, with respect to which the Indemnitor may have liability under the indemnity agreements contained herein, then upon the written acknowledgment by the Indemnitor within thirty days of the bringing of such action, suit or proceeding that it is undertaking and will prosecute the defense of the claim under such indemnity agreements and confirming that the claim is one with respect to which the Indemnitor is obligated to indemnify and that it will be able to pay the full amount of potential liability in connection with any such claim, the action, suit or proceeding (including all proceedings on appeal or for review which counsel for the Indemnitee shall deem appropriate) may be defended by the Indemnitor. However, in the event the Indemnitor shall not offer reasonable assurances as to its financial capacity to satisfy any final judgment or settlement, the Indemnitee may assume the defense and dispose of the claim, after 30 days prior written notice to the Indemnitor. The Indemnitee shall have the right to employ its own counsel in any such case, but the fees and expenses of such counsel shall be at the Indemnitee’s own expense unless (A) the employment of such counsel and the payment of such fees and expenses both shall have been specifically authorized by the Indemnitor in connection with the defense of such action, suit or proceeding or (B) the Indemnitee shall have reasonably concluded and specifically notified the Indemnitor that there may be specific defenses available to it which are different from or additional to those available to the Indemnitor.

16

(iii) In addition, in any event specified in clause (B) of the second sentence of subparagraph (ii) above, the Indemnitor, to the extent made necessary by such different or additional defenses, shall not have the right to direct the defense of such action, suit or proceeding on behalf of the Indemnitee. If Indemnitor and Indemnitee cannot agree on a mechanism to separate the defense of matters extending beyond the scope of indemnification, such matters shall be defended on the basis of joint consultation.

(iv) The Indemnitee shall be kept fully informed by the Indemnitor of such action, suit or proceeding at all stages thereof, whether or not it is represented by counsel. The Indemnitor shall, at the Indemnitor’s expense, make available to the Indemnitee and its attorneys and accountants all books and records of the Indemnitor relating to such proceedings or litigation, and the parties hereto agree to render to each other such assistance as they may reasonably require of each other in order to ensure the proper and adequate defense of any such action, suit or proceeding.

(v) The Indemnitor shall make no settlement of any claims which Indemnitor has undertaken to defend, without Indemnitee’s consent, unless the Indemnitor fully indemnifies the Indemnitee for all losses, there is no finding or admission of violation of law by, or effect on any other claims that may be made against, the Indemnitee and the relief granted in connection therewith requires no action on the part of and has no effect on the Indemnitee.
