(a) Each Seller on behalf of himself or herself and his or her agents, successors and assigns, hereby irrevocably and unconditionally releases, acquits and forever discharges each of the Company, the Subsidiary, the Purchaser and their respective Affiliates and their respective partners, shareholders, directors, officers and agents, and respective successors and assigns (collectively, the “Released Parties”), to the extent not prohibited by applicable law, from any and all charges, complaints, claims, obligations, promises, agreements, controversies, damages, actions, causes of action, suits, rights, demands, remedies, costs, losses, debts, expenses and fees, of every type, kind, nature, description or character, whether known or unknown, suspected or unsuspected, liquidated or unliquidated, including those arising out of or in connection with the Seller’s employment with the Company or the Subsidiary and any equity or other interests the Seller may have or claim to have in the Company or the Subsidiary (the “Claims”). Each Seller represents that he or she has not heretofore assigned or transferred or purported to have assigned or transferred to any Person any Claims released, acquitted and forever discharged herein. This general release shall not affect any rights that such Seller may have which arise solely under this Agreement, including payment of the Purchase Price, or that arise after the Closing Date.

25

(b) Each Seller acknowledges and agrees that the releases made herein constitute final and complete releases of the Released Parties with respect to all Claims. Such Seller expressly acknowledges and agrees that this general release is intended to include in its effect, without limitation, all Claims which such Seller does not know or suspect to exist in his or her favor at the time hereof, and this general release contemplates the extinguishment of any and all such Claims. In this regard, such Seller expressly waives the provisions of Section 1542 of the California Civil Code, which state:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

(c) Each Seller represents that he or she has not filed with any Governmental Entity any complaint, charge or lawsuit against any of the Released Parties involving any Claims released herein, and that, except as otherwise permitted by law, he or she will not do so at any time hereafter.

(e) Without limiting the foregoing, each Seller agrees that he or she will not, directly or indirectly, (i) bring or cause to be brought, or encourage or participate in the prosecution of, any action, proceeding or suit seeking recovery by or on behalf of any Person from any Released Party of any amount in respect of, or damages with respect to, any of the Claims, or (ii) defend any action, proceeding or suit in whole or in part on the grounds that any or all of the terms or provisions of this Section 4.14 are illegal, invalid, not binding, unenforceable or against public policy.

ARTICLE V

SURVIVAL; INDEMNIFICATION

5.1 Survival of Representations and Warranties. The representations and warranties made in this Agreement shall survive for two (2) years following the Closing Date. Notwithstanding the foregoing, the representations and warranties set forth in Sections 2.1, 2.5, 2.6, 2.12, 2.13, 2.15, 2.16, 2.25 and 3.4 shall survive for the applicable statute of limitations period.

5.2 Indemnification; Limitations Thereon.

(a) Each of the Founders shall, jointly and severally, indemnify the Purchaser, its Affiliates (including the Company and the Subsidiary following the Closing) and each of their respective officers, directors, employees and stockholders against and hold them harmless from any loss, Liability, diminution in value, claim, damage or expense (including reasonable legal fees and expenses), but excluding any of such loss, Liability, diminution in value, claim, damage

26

or expense as is covered by proceeds from insurance coverage, to the extent of such coverage (collectively “Damages”), suffered or incurred by any such indemnified party to the extent arising from:

(i) (A) any uncurable breach of any representation or warranty of the Sellers contained in this Agreement or any of the other Transaction Documents (subject to the disclosures made as a part of the contemplated transaction and any supplements to the Disclosure Schedule made prior to the Closing) and (B) any curable breach of any representation or warranty of the Sellers contained in this Agreement or any of the other Transaction Documents (subject to the disclosures made as a part of the contemplated transaction and any supplements to the Disclosure Schedule made prior to the Closing), to the extent such curable breach remains uncured by the Founders for at least thirty (30) days following receipt by the Founders of written notice by the Purchaser;

(ii) (A) any uncurable breach of any covenant of the Sellers contained in this Agreement and (B) any curable breach of any covenant of the Sellers contained in this Agreement, to the extent such curable breach remains uncured by the Founders for at least thirty (30) days following receipt by the Founders of written notice by the Purchaser;

(iii) any violation of any Environmental Law or any release or disposal of hazardous materials that occurred on or prior to the Closing Date in connection with the Business (whether or not such violation, release or disposal is disclosed in the Disclosure Schedule);

(iv) the payment of any severance pay benefits under any plans or programs sponsored by, or any termination fees under any employment agreement with, the Company or the Subsidiary that may become payable for any reason, including, without limitation, as a result of the transactions contemplated by this Agreement and the Transaction Documents;

(v) the payment of any Taxes (including interest and penalties) of any kind or nature imposed, whether before or after the Closing Date (except such Taxes, if any, that are adequately reserved against in the Financial Statements excluding, however, any reserve for deferred Taxes established to reflect timing differences between book and Tax income), by any Governmental Entity upon the business, assets or employees or independent contractors of the Company or the Subsidiary or otherwise resulting from or relating to the respective businesses or operations of the Company and the Subsidiary on or prior to the Closing Date or any of their respective properties or assets as they existed as of or at any time on or prior to the Closing Date and the transactions contemplated by this Agreement or the Transaction Documents, excepting therefrom any and all Taxes not yet due and payable relating to the current year income of the Company and the Subsidiary and any current payroll and property Taxes of the Company and the Subsidiary not yet due and payable as of the Closing Date;

27

(vi) any claim, suit, action, arbitration, proceeding, investigation or other similar matter relating to the repurchase and cancellation of the Plan Options and the conversion of the Non-Plan Options into Shares;

(vii) any other claim, suit, action, arbitration, proceeding, investigation or other similar matter relating to the ownership and operation of the Business and resulting from events occurring on or prior to the Closing Date (whether or not such claim, suit, action, arbitration, proceeding, investigation or other similar matter is disclosed in the Disclosure Schedule); and

(viii) the death of or injury to any person or damage to property that occurred prior to the Closing and arose out of or in connection with the business or operations of the Company and the Subsidiary (whether asserted, discovered or established before or after the Closing, and whether or not such claim or action is disclosed in the Disclosure Schedule).

No indemnity shall be sought or paid unless the aggregate amount of Damages exceeds $35,000.00, in which case the indemnity shall apply to the first dollar of Damage and all subsequent Damages. The express written waiver by the Purchaser of any condition set forth in Section 6.2 based on the inaccuracy of any representation or warranty, or on the nonperformance of or noncompliance with any covenant or obligation, will not preclude any right of the Purchaser or any other indemnified Person to indemnification, payment of Damages, or other remedy based on such representation, warranty, covenant, and obligation.

(b) The Purchaser shall indemnify the Founders, their Affiliates and each of their respective officers, directors, employees and stockholders against and hold them harmless from any Damages suffered or incurred by any such indemnified party to the extent arising from (i) any breach of any representation or warranty of the Purchaser contained in this Agreement or any of the other Transaction Documents; and (ii) any breach of any covenant of the Purchaser contained in this Agreement. The express written waiver by the Sellers of any condition set forth in Section 6.3 based on the inaccuracy of any representation or warranty, or on the nonperformance of or noncompliance with any covenant or obligation, will not preclude any right of the Founders to indemnification, payment of Damages, or other remedy based on such representation, warranty, covenant, and obligation.

(c) In no event will the Founders’ liability with respect to the matters set forth in Section 5.2(a) and Section 4.10 exceed, in the aggregate, the amount of $3,235,641.00, provided however, the Founders’ liability for claims or causes of action arising from fraud shall not be subject to such limitation. The amount stated above shall be adjusted as of the first anniversary date of the Closing Date if (i) the then current market value of the Pro Rata Shares delivered to the Founders at the Closing (calculated using the closing price per share of Purchaser Common Stock as of such anniversary date as quoted on the Nasdaq Small Cap Market or other national exchange) is less than such amount and (ii) such diminution in the value of such Pro Rata Shares was not caused, directly or indirectly, by any action of any of the Founders in any capacity. If such amount is to be adjusted pursuant to the immediately preceding sentence, such adjustment shall be equal to the differential in value (the difference

28

between the value of the Pro Rata Shares of Purchaser held by Founders on the first anniversary of the Closing Date as calculated above and $3,235,641.00).

5.3 Set-Off. In addition to the Purchaser’s rights with respect to the Escrowed Shares and any rights of set-off, off-set or other rights that the Purchaser may have at common law, by statute or otherwise, the Purchaser shall have the right to set-off against any amount that the Purchaser would otherwise be required to pay to any of the Founders or their Affiliates any amounts owing by the Founders to the Purchaser pursuant to this Article V; provided, however, that notwithstanding the Purchaser’s exercise of the right to set-off described in this Section 5.3, the Purchaser and the Founders shall remain obligated to comply with their respective obligations described in Section 5.4. The Purchaser shall provide written notice to the Founders of the nature and reason for any set-off that occurs pursuant to this Section 5.3.

5.4 Procedures Relating to Indemnification Involving Third Party Claims.

(a) In order for an indemnified party to be entitled to any indemnification provided for under this Agreement in respect of, arising out of or involving a claim or demand made by any Person not a party to this Agreement against the indemnified party (a “Third Party Claim”), such indemnified party must promptly notify the indemnifying party in writing, and in reasonable detail, of the Third Party Claim after receipt by such indemnified party of written notice of the Third Party Claim; provided, however, that failure to give such notification shall not affect the indemnification provided hereunder except to the extent the indemnifying party shall have been actually prejudiced as a result of such failure. Thereafter, the indemnified party shall promptly deliver to the indemnifying party after the indemnified party’s receipt thereof, copies of all notices and documents (including court papers) received by the indemnified party relating to the Third Party Claim.

(b) If a Third Party Claim is made against an indemnified party, the indemnifying party shall be entitled to participate in the defense thereof and, if it promptly so chooses and acknowledges its obligation to indemnify the indemnified party therefor, to assume the defense thereof with counsel selected by the indemnifying party; provided that such counsel is not reasonably objected to by the indemnified party and provided further, that the indemnified party shall have the right, but not the obligation, to assume such defense. Should the indemnifying party assume the defense of a Third Party Claim, the indemnifying party shall not be liable to the indemnified party for legal expenses subsequently incurred by the indemnified party in connection with the defense thereof. If the indemnifying party assumes such defense, the indemnified party shall have the right to participate in the defense thereof and to employ counsel (not reasonably objected to by the indemnifying party), at its own expense, separate from the counsel employed by the indemnifying party, it being understood that the indemnifying party shall control such defense.

(c) The indemnifying party shall be liable for the fees and expenses of counsel employed by the indemnified party in connection with a Third Party Claim for any period during which the indemnifying party has failed to assume the defense thereof. In connection with any Third Party Claim, the indemnified party and the indemnifying party shall cooperate in the defense or prosecution thereof.

29

(d) If the indemnifying party shall have assumed the defense of a Third Party Claim, the indemnified party shall agree to any settlement, compromise or discharge of a Third Party Claim which the indemnifying party may reasonably recommend and which by its terms obligates the indemnifying party to pay the full amount of the liability in connection with such Third Party Claim, which releases the indemnified party completely in connection with such Third Party Claim and which would not otherwise adversely affect the indemnified party. If the indemnifying party shall not have assumed the defense of a Third Party Claim, the indemnified party may settle, compromise or discharge, such Third Party Claim in good faith without the indemnifying party’s prior consent, so long as the settlement or compromise is made in good faith and is reasonable in amount given the nature of the Third Party Claim and the risk of an adverse ruling or judgment.

(e) Notwithstanding the foregoing, the indemnifying party shall not be entitled to assume the defense of any Third Party Claim (and shall be liable for the reasonable fees and expenses of counsel incurred by the indemnified party in defending such Third Party Claim) if:

(i) the Third Party Claim seeks an order, injunction or other equitable relief or relief for other than money damages against the indemnified party which the indemnified party reasonably determines, after conferring with its outside counsel, cannot be separated from any related claim for money damages, or

(ii) the indemnified party reasonably determines, after conferring with its outside counsel, that joint representation would be expected to give rise to a conflict of interest.

If such equitable relief or other relief portion of the Third Party Claim can be so separated from that for money damages, the indemnifying party shall be entitled to assume the defense of the portion relating to money damages. All claims under Section 5.2 other than Third Party Claims shall be governed by Section 5.5. Whenever insurance coverage is available and counsel is provided and/or paid for by the insurance carrier, the provisions stated above shall be modified such that the insurance coverage and/or payment shall satisfy the obligations of the indemnifying party as to same.

5.5 Other Claims. In the event any indemnified party should have a claim against any indemnifying party under this Article V which does not involve a Third Party Claim, the indemnified party shall transmit to the indemnifying party a written notice (the “Indemnity Notice”) describing in reasonable detail the nature of the claim, an estimate of the amount of Damages attributable to such claim and the basis of the indemnified party’s request for indemnification under this Agreement. If the indemnifying party does not notify the indemnified party within thirty (30) days from the indemnifying party’s receipt of the Indemnity Notice that the indemnifying party disputes such claim, the claim specified by the indemnified party in the Indemnity Notice shall be deemed a liability of the indemnifying party hereunder; provided, however, that the Purchaser shall have the option of offsetting or recouping all or any part of its Damages as provided in Section 5.3.

30

5.6 Notice to Founders. When notice is required to be given to one or more of the Founders as to an event or matter subject to indemnity as described in this Article V, the notice shall be concurrently given to each and all of the Founders pursuant to the provisions of Section 9.3. If more than one of the Founders is subject to the indemnity obligations, the time for cure or action for the Founders shall commence when notice has been delivered to all of the Founders against whom indemnity obligations are being asserted.

In the event of the bringing of any action or suit by a party hereto against another party hereunder arising out of or relating to this Agreement, which claim or suit is for equitable relief, then in that event, (i) the sole forum for resolving such disputes shall be the state and federal courts located in San Diego County, California, and each of the parties hereby irrevocably submits to such exclusive jurisdiction, and (ii) the prevailing party in such action or dispute, whether by final judgment, or out of court settlement shall be entitled to have and recover of and from the non-prevailing parties all costs and expenses of suit, including reasonable attorneys’ fees actually incurred. Any judgment or order entered in any final judgment shall contain a specific provision providing for the recovery of all costs and expenses of suit, including reasonable attorneys’ fees (collectively “Costs”) incurred in enforcing, perfecting and executing such judgment. For the purposes of this paragraph, Costs shall include, without limitation, attorneys’ fees, costs and expenses incurred in (a) appeals, (b) post-judgment motions, (c) contempt proceeding, (d) garnishment, levy, and debtor and third party examination, (e) discovery, and (f) bankruptcy litigation.

9.5 Construction. The headings herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Agreement. Unless the context clearly requires otherwise “or” is not exclusive, and “includes” means “includes, but is not limited to.”

9.8 Waiver. No waiver of any breach of the provisions of this Agreement will be deemed to have been made by any party, unless such waiver is expressed in writing and signed by the party against which it is to be enforced. The waiver by any party of any right under this Agreement or to a remedy for the breach of any of the provisions herein shall not operate nor be construed by the breaching party as a waiver of the non-breaching party’s remedies with respect to any other or continuing or subsequent breach.

39
