PURCHASE AND SALE OF NOTE AND TERMS OF NOTE

SECTION 1.01.           Purchase and Sale of Note.  The Company agrees to issue and sell to the Purchaser, and, subject to and in reliance upon the representations, warranties, terms and conditions of this Agreement, the Purchaser agrees to purchase, the Company’s Junior Secured Convertible Promissory Note (the “Note”, which term will also include any notes delivered in exchange or replacement therefor), due April 13, 2012 (the “Note Maturity Date”), in the original aggregate principal amount of $5,000,000.00.  The Note will be substantially in the form set forth in Exhibit A hereto.  The closing of such purchase and sale (the “Closing”) will be held at the office of Stradling Yocca Carlson & Rauth, P.C., 660 Newport Center Drive, Newport Beach, Suite 1600, CA 92660, on April 13, 2007 (the “Closing Date”) at 10:00 A.M., Pacific Time, or at such other time and place as the Company and the Purchaser mutually agree upon.  At the Closing, the Company will issue and deliver to the Purchaser one Note payable to the order of the Purchaser, in the principal amount of $5,000,000.00, against delivery to the Company of cash in the aggregate amount of $5,000,000, less the Purchaser’s reasonable estimated expenses to be paid by the Company pursuant to Section 7.01, which shall be payable to the Company by check, wire transfer, or delivery or transference of such sum to the Company by any combination of such methods of payment.

SECTION 1.02.           Payments and Endorsements.  Payments of principal and interest on the Note will be made directly by (i) check duly mailed or delivered to the Purchaser or, in the event of a subsequent transfer or exchange of the Note pursuant to Section 1.08 hereof, to the then registered holder of the Note (in either case, the “Holder”) at the address referred to in Schedule I or in any notice delivered by the Holder to the Company, or (ii) wire transfer to the account of the Holder referred to in Schedule I or in any notice delivered by the Holder to the Company, without any presentment or notation of payment, except that prior to any transfer of the Note, the then Holder of record will endorse on the Note a record of the date to which interest has been paid and all payments made on account of principal of the Note.

SECTION 1.03.           Interest Rate; Payment of Principal and Interest.  The Note will accrue interest at the rate of nine percent (9.00%) per annum.  The said interest shall become due quarterly in arrears and shall be payable on the last day of each fiscal quarter (each, an “Interest Payment Date”) in respect of the immediately preceding completed fiscal quarter.  The first Interest Payment Date will be June 30, 2007.  At the Company’s sole option, all interest payments due and payable through June 30, 2010 may be paid in kind at the rate of thirteen percent (13.00%) per annum, compounding quarterly, in which case the accrued interest will be added to the principal amount of the Note on the applicable

3

Interest Payment Date, and interest will accrue on the aggregate principal amount.  All interest payments due and payable after June 30, 2010 must be paid in cash.  The Note shall be due and payable in full at the Note Maturity Date unless earlier converted in accordance with Section 3 of the Note.

SECTION 1.04.           Redemption of Note.  At any time until the Note has been repaid in full, the Company may, at its sole option, redeem a portion of the outstanding principal amount of the Note, from time to time, or the entire outstanding principal amount of the Note, plus any and all accrued but unpaid interest on such principal amount, through the date of repayment (such entire outstanding principal amount, plus all such accrued but unpaid interest, hereinafter referred to for purposes of this Agreement as the “Redemption Amount”) by paying to the holder of the Note: (i) 113% of the Redemption Amount if the date of repayment occurs any time prior to or on the first anniversary of this Agreement; (ii) 109.75% of the Redemption Amount if the date of repayment occurs any time after the first anniversary of this Agreement but prior to or on the second anniversary of this Agreement; (iii) 106.50% of the Redemption Amount if the date of repayment occurs any time after the second anniversary of this Agreement but prior to or on the third anniversary of this Agreement; (iv) 103.25% of the Redemption Amount if the date of repayment occurs any time after the third anniversary of this Agreement but prior to or on the fourth anniversary of this Agreement; and (v)  100.00% of the Redemption Amount if the date of repayment occurs any time after the fourth anniversary of this Agreement but prior to or on the Note Maturity Date.

SECTION 1.05.           Conversion of Note.  All or any part of the principal plus accrued but unpaid interest on the Note may be converted at any time into a number of fully paid and nonassessable shares of Common Stock of the Company, at the sole option of the Holder, pursuant to the terms and conditions of conversion set forth in the Note.  The conversion price shall initially be $0.175, subject to adjustment pursuant to the terms of the Note.  The Company acknowledges and agrees that the conversion price of each of those certain Junior Secured Convertible Promissory Notes, issued on March 8, June 15 and September 26, 2006, respectively, shall be reduced from $0.20 to $0.175 in accordance with their terms.

SECTION 1.06.           Payment on Non-Business Days.  Whenever any payment to be made will be due on a Saturday, Sunday or a public holiday under the laws of the State of California, such payment may be made on the next succeeding business day, and such extension of time will in such case be included in the computation of payment of interest due.

SECTION 1.07.           Registration of Note.  The Company will maintain at its principal office a register of the Note and will record therein the name and address of the registered Holder of the Note, the address to which notices are to be sent and the address to which payments are to be made as designated by the Holder if other than the address of the Holder, and the particulars of all transfers, exchanges and replacements of Note.  No transfer of the Note will be valid unless made on such register for the Holder or its executors or administrators or its or their duly appointed attorney, upon surrender therefor for exchange as hereinafter provided, accompanied by an instrument in writing, in form and execution reasonably satisfactory to the Company.  The Note issued hereunder, whether originally or upon transfer, exchange or replacement of the Note, will be registered on the date of execution thereof by the Company and will be dated the date to which interest has been paid on the Note.  The Holder of the Note will be that person in whose name the Note has been so registered by the Company.  The Holder will be deemed the owner of the Note for all purposes of this Agreement and, subject to the provisions hereof, will be entitled to the principal and interest evidenced by the Note free from all equities or rights of setoff or counterclaim between the Company and the transferor of such registered holder or any previous registered holder of the Note.

SECTION 1.08.           Transfer and Exchange of Note.  The Holder of the Note may, prior to maturity or prepayment thereof, surrender the Note at the principal office of the Company for transfer or

4

exchange; provided, however, the Holder will not transfer the Note (a) to any person or entity which is not an “accredited investor” within the meaning of Rule 501 under the Securities Act of 1933, as amended (the “Securities Act”), (b) to any person or entity that could result in the loss of the exemption from registration under the Securities Act applicable to the original sale of the Note, as determined in the reasonable discretion of the Company pursuant to a written opinion of the Company’s counsel, (c) so long as no Event of Default has occurred, without the consent of the Company, which consent will not be unreasonably withheld, and (d) to any person or entity unless such person or entity shall have agreed in writing to be bound by the terms of this Agreement.  Within a reasonable time after notice to the Company from the Holder of its intention to make such exchange and without expense (other than transfer taxes, if any) to the Holder, subject to the Company’s consent, if such consent is required by this Section 1.08, the Company will issue in exchange therefor another Note, in such denomination as requested by the Holder, for the same aggregate principal amount as the unpaid principal amount of the Note so surrendered and having the same maturity and rate of interest, containing the same provisions and subject to the same terms and conditions as the Note so surrendered.  The new Note will be made payable to such person or persons, or registered assigns, as the Holder of such surrendered Note may designate, and such transfer or exchange will be made in such a manner that no gain or loss of principal or interest will result therefrom.

SECTION 1.09.           Replacement of Note.  Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of any Note and, if requested in the case of any such loss, theft or destruction, upon delivery of an indemnity bond or other agreement or security reasonably satisfactory to the Company, or, in the case of any such mutilation, upon surrender and cancellation of such Note, the Company will issue a new Note, of like tenor and amount and dated the date to which interest has been paid, in lieu of such lost, stolen, destroyed or mutilated Note; provided, however, if any Note of which the Purchaser is the registered holder is lost, stolen or destroyed, the affidavit of the President, Treasurer or any Assistant Treasurer or any other authorized representative of the Purchaser setting forth the circumstances with respect to such loss, theft or destruction will be accepted as satisfactory evidence thereof, and no indemnification bond or other security will be required as a condition to the execution and delivery by the Company of a new Note in replacement of such lost, stolen or destroyed Note other than the Purchaser’s written agreement to indemnify the Company.

SECTION 1.10.           Events of Default.  If any of the following events (“Events of Default”) shall occur and be continuing:

(a)                                  The Company will fail to pay any installment of principal of, or interest due on, the Note within five (5) calendar days of the date such installment is due;

(b)                                  Any material representation or warranty made by the Company or DynTek Services, Inc. a Delaware corporation and a wholly-owned subsidiary of the Company (“DSI”), in this Agreement or the Security and Pledge Agreement (as hereinafter defined), or by the Company or DSI (or any officers of the Company or DSI) in any certificate, instrument or written statement contemplated by or made or delivered pursuant to or in connection with this Agreement or the Security and Pledge Agreement will prove to have been incorrect when made in any material respect;

5

(d)                                  The Company or any of its subsidiaries, will fail to pay any indebtedness in excess of an aggregate of $100,000 for borrowed money (other than as evidenced by the Note) owing by the Company or any of its subsidiaries, or any interest or premium thereon, when due (or, if permitted by the terms of the relevant document, within any applicable grace period), whether such indebtedness will become due by scheduled maturity, by required prepayment, by acceleration, by demand or otherwise, or will fail to perform any term, covenant or agreement on its part to be performed under any agreement or instrument evidencing or securing or relating to any indebtedness in excess of an aggregate of $100,000 owing by the Company or any of its subsidiaries when required to be performed (or, if permitted by the terms of the relevant document, within any applicable grace period), if the effect of such failure to pay or perform is to accelerate, or to permit the holder or holders of such indebtedness, or the trustee or trustees under any such agreement or instrument to accelerate, the maturity of such indebtedness, unless such failure to pay or perform will be waived by the holder or holders of such indebtedness or such trustee or trustees;

(e)                                  The Company or any of its subsidiaries will be involved in financial difficulties as evidenced (i) by its admitting in writing its inability to pay its debts generally as they become due; (ii) by its commencement of a voluntary case under Title 11 of the United States Code as from time to time in effect; (iii) by its filing an answer or other pleading admitting or failing to deny the material allegations of a petition filed against it commencing an involuntary case under said Title 11, or seeking, consenting to or acquiescing in the relief therein provided, or by its failing to controvert timely the material allegations of any such petition; (iv) by the entry of an order for relief in any involuntary case commenced under said Title 11; (v) by its seeking relief as a debtor under any applicable law, other than said Title 11, of any jurisdiction relating to the liquidation or reorganization of debtors or to the modification or alteration of the rights of creditors, or by its consenting to or acquiescing in such relief; (vi) by the entry of an order by a court of competent jurisdiction (a) finding it to be bankrupt or insolvent, (b) ordering or approving its liquidation, reorganization or any modification or alteration of the rights of its creditors, or (c) assuming custody of, or appointing a receiver or other custodian for, all or a substantial part of its property; or (vii) by its making an assignment for the benefit of, or entering into a composition with, its creditors, or appointing or consenting to the appointment of a receiver or other custodian for all or a substantial part of its property; or

(f)                                    Any judgment, writ, warrant of attachment or execution or similar process will be issued or levied against a substantial part of the property of the Company or any of its subsidiaries and such judgment, writ, or similar process will not be released, vacated or fully bonded within sixty (60) days after its issue or levy;

then, and in any such event, any holder of the Note may, by notice to the Company, declare the entire unpaid principal amount of the Note, all interest accrued and unpaid thereon and all other amounts payable under this Agreement to be forthwith due and payable, whereupon the Note, all such accrued interest and all such amounts will become and be forthwith due and payable (unless there will have occurred an Event of Default under subsection 1.15(e) in which case all such amounts will automatically become due and payable), without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Company.

ARTICLE VI

REGISTRATION

SECTION 6.01.           Piggyback Registration.  If, at anytime prior to the fifth anniversary of this Agreement, the Company proposes to register (including for this purpose a registration effected by the Company for stockholders other than the Holder) the sale of any of its securities under the Securities Act, then the Company will promptly give the Holder written notice thereof and will use its reasonable best efforts to include in such registration (A) all or any part of the shares of Common Stock issuable by the Company upon the exercise of the Note (the “Registrable Securities”).  This requirement does not apply to Company registrations on Form S-4 or S-8 or their equivalents relating to equity securities to be issued solely in connection with an acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans.  The Holder must give its request for registration under this paragraph to the Company in writing within 10 days after receipt from the Company of notice of such pending registration.  If the registration for which the Company gives notice is a public offering involving an underwriting, the Company will so advise the Holder as part of the above-described written notice.  In that event, if the managing underwriter(s) of the public offering impose a limitation on the number of shares of Common Stock that may be included in the Registration Statement because, in such underwriter(s)’ judgment, such limitation would be necessary to effect an orderly public distribution, then the Company will be obligated to include only such limited portion, if any, of the Registrable Securities with respect to which the Holder has requested inclusion hereunder.  Any exclusion of Registrable Shares will be made pro rata among all holders of the Company’s securities seeking to include shares of Common Stock in proportion to the number of shares of Common Stock sought to be included by those holders.  However, the Company will not exclude any Registrable Securities unless the Company has first excluded all outstanding securities the holders of which are not entitled by right to inclusion of such securities in such Registration Statement or are not entitled pro rata inclusion with the Registrable Securities.

SECTION 6.02.           Mandatory Registration.  If, at anytime on or after the one year anniversary of this Agreement, the resale of any Registrable Securities have not been registered by the Company pursuant to Section 6.01 hereof, the Purchaser may deliver notice to the Company to require that the Company register all Registrable Securities on a registration statement on Form S-1, or other form then available to the Company under applicable SEC rules and regulations (the “Registration Statement”), covering the resale of all of the Registrable Securities.  The date on which the Company receives such notice is referred to herein as the “Demand Date.”  The Company shall use commercially reasonable best efforts (i) to cause such Registration Statement to be filed under the Securities Act as promptly as practicable after receipt of notice of such demand, but in any event not more than 30 days following the Demand Date and (ii) to cause such Registration Statement to be declared effective under

16

the Securities Act as promptly as practicable, but in any event no later than 90 days following the Demand Date (the “Demand Effective Date”).  However, so long as the Company has filed the Registration Statement within 30 days after the Demand Date, (a) if the SEC takes the position that registration of the resale of the Registrable Securities by the Holder is not available under applicable laws, rules and regulations and that the Company must register the offering of the Registrable Securities as a primary offering by the Company, or (b) if the Registration Statement receives SEC review, then the Demand Effective Date will be the 120th day after the Demand Date.  In the case the SEC takes the position that resale registration is not available, the Company will, within 40 business days after the date the Company receives such SEC response, file a Registration Statement as a primary offering.  The Company’s best efforts will include, without limitation, promptly responding to all comments received from the staff of the SEC.  If the Company receives notification from the SEC that the Registration Statement will receive no action or review from the SEC, then the Company will cause the Registration Statement to become effective within five business days after such SEC notification, if permitted by the SEC and applicable rules and regulations.  Once the Registration Statement is declared effective by the SEC, the Company will cause the Registration Statement to remain effective throughout the Registration Period, except as permitted under this Section.  “Registration Period” means the period between the Demand Date and the earlier of the date on (i) which (x) all of the Registrable Securities have been sold by the Holder pursuant to a Registration Statement and (y) are freely tradable under the Securities Act, or (ii) all the Registrable Securities may be immediately sold by the Holder without registration and without restriction as to the number of Registrable Securities to be sold, pursuant to Rule 144 or otherwise.  On the date of each monthly anniversary of the date on which any breach of this Section 6.02 first occurs (including failure to file a Registration Statement or to cause a Registration Statement to be declared effective within the time periods set forth herein) until the applicable default is cured (each, a “Payment Date”), the Company shall issue to the Holder as damages additional shares of the Company’s Common Stock equal to 2.0% of the aggregate amount of the Registrable Securities, and all such shares shall become Registrable Securities; provided, however, that the total number of shares of the Company’s Common Stock payable pursuant to this Section 6.02 to the Holder shall not exceed the number of shares, less one share, which, if issued, would have, at the time of the Closing Date or Payment Date, required stockholder approval of such issuance pursuant to Section 4350(i)(1)(D) of the Nasdaq Marketplace Rules, or other applicable rules and regulations of another exchange if the Company’s securities are listed for trading on such other exchange, if the Company is then subject to any such rule.  In the event the number of shares of the Company’s Common Stock issuable under this Section 6.02 is restricted by the limitations of the previous sentence, the Company may waive such limitation or, at the Company’s election, the balance of the damages payable by the Company pursuant to this Section 6.02 may be paid in cash (valuing the shares not so issued at the average of the closing prices of the Company’s Common Stock over the twenty (20) trading days immediately preceding the one-month anniversary of the default which requires the issuance of shares) on the applicable Payment Date in accordance with payment instructions provided by the Purchaser.

SECTION 6.03.           Continued Effectiveness of Registration Statement.  Subject to the limitations set forth in Section 6.08, the Company will keep the Registration Statement covering the Registrable Securities effective under Rule 415 at all times during the Registration Period.  In the event that the number of shares available under a Registration Statement filed pursuant to this Agreement is insufficient to cover all of the Registrable Securities issued, the Company will, if permitted by the SEC, either amend the Registration Statement or file a new Registration Statement (on the short form available therefor, if applicable), or both, so as to cover all of the Registrable Securities.  The Company will use its reasonable best efforts to file such amendment or new Registration Statement as soon as practicable, but in no event later than 30 business days after the necessity therefor arises (based upon the market price of the Common Stock and other relevant factors on which the Company reasonably elects to rely).  The Company will use its best efforts to cause such amendment or new Registration Statement to become

17

effective as soon as is practicable after the filing thereof, but in no event later than 90 days after the date on which the Company reasonably first determines the need therefor, if permitted by the SEC.

SECTION 6.04.           Accuracy of Registration Statement.  Any Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) filed by the Company covering Registrable Securities will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading.  The Company will prepare and file with the SEC such amendments (including post-effective amendments) and supplements to any Registration Statement and the prospectus used in connection with such Registration Statement as may be necessary to permit sales pursuant to such Registration Statement at all times during the Registration Period, and, during such period, will comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities of the Company covered by such Registration Statement until the termination of the Registration Period, or if earlier, until such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such Registration Statement.

SECTION 6.05.           Furnishing Documentation.  The Company will furnish to the Holder, or to its legal counsel, (a) promptly after such document is filed with the SEC, one copy of any Registration Statement filed pursuant to this Agreement and any amendments thereto, each preliminary prospectus and final prospectus and each amendment or supplement thereto; and (b) a number of copies of a prospectus, including a preliminary prospectus, and all amendments and supplements thereto, and such other documents as the Holder may reasonably request in order to facilitate the disposition of the Registrable Securities owned by the Holder.  The Company will promptly notify by facsimile or email the Holder of the effectiveness of any Registration Statement and any post-effective amendment.

SECTION 6.06.           Additional Obligations.  The Company will use its best efforts to (a) register and qualify the Registrable Securities covered by a Registration Statement under such other securities or blue sky laws of such jurisdictions as the Holder reasonably requests, (b) prepare and file in those jurisdictions any amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain their effectiveness during the Registration Period, (c) take any other actions necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (d) take any other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions.  Notwithstanding the foregoing, the Company is not required, in connection with such obligations, to (i) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 6.06, (ii) subject itself to general taxation in any such jurisdiction, (iii) file a general consent to service of process in any such jurisdiction, (iv) provide any undertakings that cause material expense or material burden to the Company, or (v) make any change in its charter or bylaws, which in each case the Board of Directors of the Company determines to be contrary to the best interests of the Company and its stockholders.

SECTION 6.07.           Underwritten Offerings.  If the Holder selects an underwriter or underwriters reasonably acceptable to the Company for an underwritten offering, the Company will enter into and perform its obligations under an underwriting agreement in usual and customary form including, without limitation, customary indemnification and contribution obligations, with the managing underwriter of such offering.

SECTION 6.08.           Suspension of Registration.

(a)                                  The Company will notify (by telephone and also by facsimile and reputable overnight courier) the Holder of the happening of any event of which the Company has knowledge as a

18

result of which the prospectus included in a Registration Statement as then in effect includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.  The Company will make such notification as promptly as practicable (but in no event more than two business days) after the Company becomes aware of the event, will promptly (but in no event more than ten business days) prepare and file a supplement or amendment to such Registration Statement to correct such untrue statement or omission, and will deliver a number of copies of such supplement or amendment to the Holder as it may reasonably request.

(b)                                  Notwithstanding the obligations under Section 6.08(a), if in the good faith judgment of the Company, following consultation with legal counsel, it would be detrimental to the Company and its stockholders for resales of Registrable Securities to be made pursuant to a Registration Statement due to the existence of a material development or potential material development involving the Company which the Company would be obligated to disclose in such Registration Statement, but which disclosure would be premature or otherwise inadvisable at such time or would reasonably be expected to have a material adverse effect upon the Company and its stockholders, the Company will have the right to suspend the use of such Registration Statement for a period of not more than forty-five (45) days; provided, however, that the Company may so defer or suspend the use of a Registration Statement no more than one time in any twelve-month period.

(c)                                  Subject to the Company’s rights under this Article VI, the Company will use its reasonable best efforts to prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement and, if such an order is issued, will use its best efforts to obtain the withdrawal of such order at the earliest possible time and to notify the Holder of the issuance of such order and the resolution thereof.

(d)                                  Notwithstanding anything to the contrary contained in this Agreement, if the use of a Registration Statement is suspended by the Company, the Company will promptly (but in no event more than two business days) give notice of the suspension to the Holder, and will promptly (but in no event more than two business days) notify the Holder as soon as the use of such Registration Statement may be resumed.

SECTION 6.09.           Transfer Agent; Registrar.  The Company will provide a transfer agent and registrar, which may be a single entity, for the Registrable Securities not later than the effective date of a Registration Statement.

SECTION 6.10.           Share Certificates.  The Company will cooperate with the Holder and with the managing underwriter(s), if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing Registrable Securities to be offered pursuant to a Registration Statement and will enable such certificates to be in such denominations or amounts as the case may be, and registered in such names as the Holder or the managing underwriter(s), if any, may reasonably request.

SECTION 6.11.           Plan of Distribution.  At the reasonable request of the Holder, the Company will promptly prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration Statement, and the prospectus used in connection with such Registration Statement, as may be necessary in order to change the plan of distribution set forth in such Registration Statement.

SECTION 6.12.           Securities Laws Compliance.  The Company will comply with all applicable laws related to any Registration Statement relating to the offer and sale of Registrable

19

Securities and with all applicable rules and regulations of governmental authorities in connection therewith (including, without limitation, the Securities Act, the Exchange Act and the rules and regulations promulgated by the SEC).

SECTION 6.13.           Further Assurances.  The Company will take all other reasonable actions as the Holder or the underwriters, if any, may reasonably request to expedite and facilitate disposition by the Holder of the Registrable Securities pursuant to any Registration Statement.

SECTION 6.14.           Expenses.  The Company will bear all reasonable expenses, other than underwriting discounts and commissions, and transfer taxes, if any, incurred in connection with registrations, filings or qualifications pursuant to Article VI of this Agreement, including, without limitation, all registration, listing and qualifications fees, printers and accounting fees, the fees and disbursements of counsel for the Company, and the reasonable fees and disbursements of the Holder’s legal counsel.

SECTION 6.15.           Indemnification.  In the event that any Registrable Securities are included in a Registration Statement under this Agreement:

(a)                                  To the extent permitted by law, the Company will indemnify, defend and hold harmless the Holder, and agents, employees, attorneys, accountants, underwriters (as defined in the Securities Act) for the Holder and any directors or officers of such Holder or such underwriter and any person who controls the Holder or such underwriter within the meaning of the Securities Act or the Exchange Act (each, a “Holder Indemnified Person”) against any losses, claims, damages, expenses or liabilities (collectively, and together with actions, proceedings or inquiries by any regulatory or self-regulatory organization, whether commenced or threatened in respect thereof, “Claims”) to which any of them become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Claims arise out of or are based upon any of the following statements, omissions or violations in a Registration Statement filed pursuant to this Agreement, any post-effective amendment thereof or any prospectus included therein:  (a) any untrue statement or alleged untrue statement of a material fact contained in a Registration Statement or any post-effective amendment thereof or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (b) any untrue statement or alleged untrue statement of a material fact contained in the prospectus or any preliminary prospectus (as it may be amended or supplemented) or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading, or (c) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or any other law, including without limitation any state securities law or any rule or regulation thereunder (the matters in the foregoing clauses (a) through (c) being, collectively, “Violations”).  Subject to the restrictions set forth herein with respect to the number of legal counsel, the Company will reimburse the Holder and each such attorney, accountant, underwriter or controlling person and each such other Holder Indemnified Person, promptly as such expenses are incurred and are due and payable, for any legal fees or other reasonable expenses incurred by them in connection with investigating or defending any Claim.  Notwithstanding anything to the contrary contained herein, the indemnification contained in this Section 6.15 (i) does not apply to a Claim by a Holder Indemnified Person arising out of or based upon a Violation that occurs in reliance upon and in conformity with information furnished in writing to the Company by such Holder Indemnified Person expressly for use in each Registration Statement or any such amendment thereof or supplement thereto, if such prospectus or supplement thereto was timely made available by the Company; and (ii) does not apply to amounts paid in settlement of any Claim if such settlement is made without the prior written consent of the Company, which consent will not be unreasonably withheld. This indemnity obligation will remain in full force and effect regardless of any investigation made by or on behalf of the Holder Indemnified Persons and will survive the transfer of the Registrable Securities by the Holder.

(b)                                  In connection with any Registration Statement in which the Holder is participating, such Holder will indemnify and hold harmless, the Company, each of its directors, each of its officers who signs any Registration Statement, each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, and any other stockholder selling securities pursuant to a Registration Statement or any of its directors or officers or any person who controls such stockholder within the meaning of the Securities Act or the Exchange Act (each a “Company Indemnified Person”) against any Claim to which any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Claim arises out of or is based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Purchaser expressly for use in such Registration Statement.  Such Holder will promptly reimburse each Company Indemnified Person for any legal or other expenses (promptly as such expenses are incurred and due and payable) reasonably incurred by them in connection with investigating or defending any such Claim.  However, the indemnity agreement contained in this section does not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Holder, which consent will not be unreasonably withheld, and the Holder will not be liable under this Agreement for the amount of any Claim that exceeds the net proceeds actually received by the Holder as a result of the sale of Registrable Securities pursuant to such Registration Statement.  This indemnity will remain in full force and effect regardless of any investigation made by or on behalf of a Company Indemnified Party and will survive the transfer of the Registrable Securities by the Holder.

(c)                                  If any proceeding shall be brought or any claim asserted against any person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party promptly shall notify the person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the Indemnifying Party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all reasonable fees and expenses incurred in connection with defense thereof; provided, however, that the failure of any Indemnified Party to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that such failure shall have proximately and materially adversely prejudiced the Indemnifying Party.

(d)                                  An Indemnified Party shall have the right to employ separate counsel in any such proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Indemnified Parties unless: (i) the Indemnifying Party has agreed in writing to pay such fees and expenses; (ii) the Indemnifying Party shall have failed promptly to assume the defense of such proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such proceeding; or (iii) the named parties to any such proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have been advised by counsel that a conflict of interest is likely to exist if the same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense thereof and such counsel shall be at the reasonable expense of the Indemnifying Party; provided, however, that in no event shall the Indemnifying Party be responsible for the fees and expenses of more than one separate counsel).  The Indemnifying Party shall not be liable for any settlement of any such proceeding effected without its written consent, which consent shall not be unreasonably withheld.  No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending proceeding in respect of which any Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on Claims that are the subject matter of such proceeding.

21

(e)                                  Subject to the foregoing, all reasonable fees and expenses of the Indemnified Party (including fees and expenses to the extent incurred in connection with investigating or preparing to defend such proceeding in a manner not inconsistent with this Section) shall be paid to the Indemnified Party, as incurred, within ten (10) business days of written notice thereof to the Indemnifying Party, which notice shall be delivered no more frequently than on a monthly basis (regardless of whether it is ultimately determined that an Indemnified Party is not entitled to indemnification hereunder; provided, that the Indemnifying Party may require such Indemnified Party to undertake to reimburse all such fees and expenses to the extent it is finally judicially determined that such Indemnified Party is not entitled to indemnification hereunder).

SECTION 6.16.                                    Transfer.  The rights of the Holder hereunder, including the right to have the Company register Registrable Securities pursuant to this Agreement, may be assigned by the Holder to transferees or assignees of all or any portion of the Registrable Securities, but only if (a) the Holder agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (b) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being transferred or assigned, (c) after such transfer or assignment, the further disposition of such securities by the transferee or assignee is restricted under the Securities Act and applicable state securities laws, (d) at or before the time the Company received the written notice contemplated by clause (b) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein, (e) such transfer is made in accordance with the applicable requirements of this Agreement, and (f) the transferee is an “accredited investor” as that term is defined in Rule 501 of Regulation D.

23

SECTION 7.10.           Severability.  If any provision of this Agreement will be declared void or unenforceable by any judicial or administrative authority, the validity of any other provision and of the entire Agreement will not be affected thereby.

SECTION 7.11.           Titles and Subtitles.  The titles and subtitles used in this Agreement are for convenience only and are not to be considered in construing or interpreting any term or provision of this Agreement.

SECTION 7.12.           No Publicity.  Except as expressly provided below, no party will make, issue or release any public announcement, press release, statement or acknowledgment (collectively, “Public Announcement”) of the existence of, or reveal publicly the terms, conditions and status of, the transactions contemplated hereby, without the prior written consent of the other party as to the content and time of release of and the media in which such Public Announcement is to be made; provided, however, that in the case of a Public Announcement which a party is required by law to make, issue or release, the making, issuing or releasing of any such Public Announcement, by a party so required to do so will not constitute a breach if such party has given, to the extent reasonably possible, not less than two (2) business days prior notice to the other party, and has attempted, to the extent reasonably possible, to allow the other party to review and approve such Public Announcement; provided further, however, that upon the Company’s making of a Public Announcement regarding the existence of, or the terms, conditions and status of, the transactions contemplated hereby, whether pursuant to the filing of a Form 8-K or otherwise, subject to the consent of the Company, which consent may not be unreasonably withheld, the Purchaser may advertise the closing of the transactions contemplated by this Agreement, and make appropriate announcements of the financial arrangements entered into among the parties hereto, including, without limitation, announcements commonly known as tombstones, in such trade publications, business journals, newspapers of general circulation and to such selected parties as the Purchaser will deem reasonably appropriate.

SECTION 7.13.           Usury Savings Clause.  The parties intend to comply at all times with applicable usury laws.  If at any time such laws would render usurious any amounts due under the Note under applicable law, then it is the parties’ express intention that the Company not be required to pay interest on the Note at a rate in excess of the maximum lawful rate, that the provisions of this Section 7.13 will control over all other provisions of the Note which may be in apparent conflict hereunder, that such excess amount will be immediately credited to the principal balance of the Note (or, if the Note has been fully paid, refunded by the Holder to the Company), and the provisions thereof will immediately reformed and the amounts thereafter decreased, so as to comply with the then applicable usury law, but also so as to permit the recovery of the fullest amount otherwise due under the Note.  The Company hereby represents and warrants that its assets are sufficient to meet the requirements for exemption from the usury laws of the State of California as provided by Section 25118 of the California Corporations Code or any successor statute.
