W I T N E S S E T H:

WHEREAS, the respective Boards of Directors of Parent, Sub and the Company have approved and declared advisable the merger of Sub and the Company (the “Merger”), upon the terms and subject to the conditions set forth herein, whereby each issued and outstanding share of common stock, $0.001 par value, of the Company (“Company Common Shares”), and each issued and outstanding share of preferred stock, $0.001 par value, of the Company (“Company Preferred Shares”, and together with the Company Common Shares, the “Company Shares”), of which 2,428,571 shares have been designated as Series A Preferred Stock (“Company Series A Preferred Shares”), 12,428,572 shares have been designated as Series B Preferred Stock (“Company Series B Preferred Shares”), 11,766,087 shares have been designated as Series B-1 Preferred Stock (“Company Series B-1 Preferred Shares”) and 10,778,443 shares have been designated as Series C Preferred Stock (“Company Series C Preferred Shares”), not owned directly or indirectly by Parent or the Company, will be converted into the right to receive a portion of the Aggregate Merger Consideration (as defined herein);

WHEREAS, the respective Boards of Directors of Parent and the Company have determined that the Merger is advisable to and in the best interest of their respective stockholders;

WHEREAS, in order to induce Parent and Sub to enter into this Agreement, concurrently herewith, the directors and certain stockholders of the Company are entering into agreements with Parent dated as of the date hereof (the “Support and Release Agreements”), in the form of the attached Exhibit A, pursuant to which, among other things, each such stockholder has agreed to vote in favor of this Agreement and the Merger and, in the case of certain stockholders, to certain prohibitions on competition and solicitation; and

Section 1.1 The Merger. Upon the terms and subject to the conditions set forth in this Agreement, and in accordance with the Delaware General Corporation Law (the “DGCL”), Sub shall be merged with and into the Company at the Effective Time (as hereinafter defined). Following the Merger, the separate corporate existence of Sub shall cease and the Company shall continue as the surviving corporation (the “Surviving Corporation”) and shall succeed to and assume all the rights and obligations of Sub in accordance with the DGCL. Notwithstanding anything to the contrary herein, at the election of Parent, any direct wholly owned Subsidiary (as hereinafter defined) of Parent may be substituted for Sub as a Constituent Corporation in the Merger; provided that such substituted corporation is a Delaware corporation which is formed solely for the purpose of engaging in the transactions contemplated by this Agreement and has engaged in no other business activities. In such event, the parties agree to execute an appropriate amendment to this Agreement, in form and substance reasonably satisfactory to Parent and the Company, in order to reflect such substitution.

Section 1.2 Effective Time. The Merger shall become effective when the Certificate of Merger (the “Certificate of Merger”), executed in accordance with the relevant provisions of the DGCL, is filed with the Secretary of State of the State of Delaware; provided, however, that, upon mutual consent of the Constituent Corporations, the Certificate of Merger may provide for a later date of effectiveness of the Merger not more than thirty (30) days after the date the Certificate of Merger is filed.

Section 1.4 Charter and Bylaws; Directors and Officers.

(a) At the Effective Time, the Certificate of Incorporation, as amended, of the Company (the “Company Charter”), as in effect immediately prior to the Effective Time, shall be amended so that it reads in its entirety as set forth in the attached Exhibit C.As so amended, the Company Charter shall be the Certificate of Incorporation of the Surviving Corporation until thereafter changed or amended as provided therein or by applicable law.

(b) The directors and officers of Sub at the Effective Time shall be the directors and officers of the Surviving Corporation, until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be.

Section 1.5 Conversion of Securities. As of the Effective Time, by virtue of the Merger and without any action on the part of Sub, the Company or the holders of any

securities of the Constituent Corporations:

(a) Each issued and outstanding common share, $0.001 par value, of Sub shall be converted into one validly issued, fully paid and nonassessable share of common stock of the Surviving Corporation.

(b) All Company Shares that are held in the treasury of the Company or by any wholly owned Subsidiary of the Company and any Company Shares owned by Parent shall be canceled, and no capital stock of Parent or other consideration shall be delivered in exchange therefor.

(c) Subject to the provisions of this Article I, the Company Shares issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares (as hereinafter defined) and shares to be canceled in accordance with Section 1.5(b)) shall be converted into the right to receive the Aggregate Merger Consideration. Subject to the provisions of Section 1.5(e), each Company Share issued and outstanding immediately prior to the Effective Time (other than Dissenting Shares and shares to be canceled in accordance with Section 1.5(b)) shall be converted as follows:

(i) each Company Series A Preferred Share shall be converted into the right to receive, in cash and without interest or dividends, the greater of $0.35 (the “Series A Per Share Consideration”) and the Common Per Share Consideration (as hereinafter defined);

(ii) each Company Series B Preferred Share shall be converted into the right to receive, in cash and without interest or dividends, the greater of $0.683908 (the “Series B Per Share Consideration”) and the Common Per Share Consideration;

(iii) each Company Series B-1 Preferred Share shall be converted into the right to receive, in cash and without interest or dividends, the greater of $1.27485 (the “Series B-1 Per Share Consideration”) and the Common Per Share Consideration;

(iv) each Company Series C Preferred Share shall be converted into the right to receive, in cash and without interest or dividends, the greater of $1.67 (the “Series C Per Share Consideration”) and the Common Per Share Consideration; and

(v) each Company Common Share shall be converted into the right to receive, in cash and without interest or dividends, the Common Share Consideration (as hereinafter defined) divided by the aggregate number of Company Common Shares and Company Preferred Shares issued and outstanding immediately prior to the Effective Time on a fully diluted basis (assuming the exercise of all Company Stock Options (as hereinafter defined), excluding only the Company Unvested Stock Options (as hereinafter defined)) (the “Common Per Share Consideration”).

Such shares, when so converted, shall no longer be outstanding and shall automatically be canceled and retired, and each holder of a certificate representing any such shares shall cease to have any rights with respect thereto, except the right to receive such amount.

(d) Subject to the provisions of this Article I, each Company Vested Stock Option (as hereinafter defined) issued and outstanding immediately prior to the Effective Time shall be canceled, terminated and relinquished and shall be converted into the right to receive, with respect to each Company Common Share subject thereto, the Common Per Share Consideration minus the exercise price thereof under such Company Vested Stock Option, subject to applicable withholding requirements.

(e) Notwithstanding anything in this Agreement to the contrary, Company Shares issued and outstanding immediately prior to the Effective Time which are held of record by any stockholder who shall not have voted such shares (or granted his or its consent with respect to such shares) in favor of the Merger and who shall have demanded properly in writing appraisal of such shares in accordance with Section 262 of the DGCL or, to the extent applicable, Chapter 13 of the California Corporations Code (“Dissenting Shares”) shall not be converted into the right to receive a portion of the Aggregate Merger Consideration set forth in Section 1.5(c), but the holders thereof instead shall be entitled to, and the Dissenting Shares shall only represent the right to receive, payment of the fair value of such shares in accordance with the provisions of Section 262 of the DGCL or, to the extent applicable, Chapter 13 of the California Corporations Code (the “CCC”); provided, however, that (i) if such a holder fails to demand properly in writing from the Surviving Corporation the appraisal of his or its shares in accordance with Section 262(d) of the DGCL or, to the extent applicable, Chapter 13 of the CCC or, after making such demand, subsequently delivers an effective written withdrawal of such demand, or fails to establish his or its entitlement to appraisal rights as provided in Section 262 of the DGCL or, to the extent applicable, Chapter 13 of the CCC, if so required, or (ii) if a court shall determine that such holder is not entitled to receive payment for his or its shares or such holder shall otherwise lose his or its appraisal rights, then, in any such case, each Company Share held of record by such holder or holders shall automatically be converted into and represent only the right to receive a portion of the Aggregate Merger Consideration as set forth in Section 1.5(c), upon surrender of the certificate or certificates representing such Dissenting Shares, delivery of the Transmittal Letter (as hereinafter defined) and complying with the other provisions of this Article I. Any cash paid in respect of Dissenting Shares shall be paid by the Company solely with its own funds, and the Company shall not be reimbursed therefor by Parent or any of its Subsidiaries, either directly or indirectly.

(f) Any amount paid by Parent, the Company or the Surviving Corporation to any Person (as hereinafter defined) with respect to Dissenting Shares pursuant to Section 262 of the DGCL or, to the extent applicable, Chapter 13 of the CCC, as applicable, in excess of the amount that would otherwise be payable pursuant to Section 1.5(c) for each such Dissenting Share (such amount, unless determined in a final, non-appealable judgment of a court, being subject to the written approval of the Stockholders Representative, which approval shall not be unreasonably withheld, conditioned or delayed) and all Losses (as hereinafter defined) and Expenses (as hereinafter defined) incurred by the Company, Parent, or the Surviving Corporation in connection with or arising from the exercise of all rights under Section 262 of the DGCL or, to the extent applicable, Chapter 13 of the CCC shall constitute a Loss for purposes of this Agreement, and Parent and the Surviving Corporation shall, without limiting any other rights, be entitled to indemnification for such Loss under Article VIII hereof.

(g) In calculating the consideration payable under this Section 1.5, Parent shall be entitled to rely on the representations and warranties contained in Section 3.2 and the certificate delivered pursuant to Section 6.3(f). If such representations, warranties and certificate are not correct, in addition to its rights under Article VIII, (i) Parent shall have the right to adjust the amount payable in respect of each Company Share and Company Stock Option accordingly and be indemnified in respect thereof pursuant to Article VIII and (ii) notwithstanding anything else to the contrary contained in this Agreement, in no event shall the aggregate merger consideration payable by Parent, Sub or the Surviving Corporation to the holders of equity interests in the Company (other than as expressly provided in Section 5.4 with respect to holders of the Company Unvested Stock Options) in connection with the Merger or the transactions contemplated hereby exceed the Aggregate Merger Consideration.

The Company will, through its Board of Directors, recommend to the Company’s stockholders approval of this Agreement and shall use all reasonable efforts to solicit such written consent. The Company agrees to submit this Agreement to the Company’s stockholders for approval whether or not the Board of Directors of the Company determines at any time subsequent to the date hereof that this Agreement is no longer advisable and recommends that the Company’s stockholders reject it.

Section 5.2 Access to Information. The Company shall, and shall cause each of its Subsidiaries to, afford to the accountants, counsel, financial advisors and other representatives of Parent reasonable access to, and permit them to make such inspections as they may reasonably require of all of its employees, customers, properties, books, contracts, commitments and records (including the work papers of independent accountants, if available and subject to the consent of such independent accountants) during normal business hours during the period from the date of this Agreement through the Effective Time and, during such period, the Company shall, and shall cause each of its Subsidiaries to, furnish promptly to Parent all information concerning its business, properties and personnel as the other may reasonably request.

Section 5.4 Stock Options.

(a) Not later than immediately prior to the Effective Time, the Company shall cause each Company Stock Option that is outstanding and exercisable immediately prior to the Effective Time (a “Company Vested Stock Option”) held by any Company director, officer or employee to be exercised in its entirety in accordance with the terms of such Company Stock Option and the Company Common Shares purchased pursuant to such Company Vested Stock Option to be issued to the holder thereof. The Company shall use its commercially reasonable best efforts so that no later than immediately prior to the Effective Time, each Company Vested Stock Option held by Persons who are not directors, officers or employees of the Company shall be so exercised and the Company Common Shares purchased pursuant thereto shall be issued to the holder thereof.

(b) Not later than the Effective Time, each Company Stock Option that is outstanding and not exercisable immediately prior to the Effective Time (a “Company Unvested Stock Option”) shall become and represent an unexercisable option (the “Substitute Option”) to purchase the number of shares of common stock of Parent (“Parent Common Shares”) (decreased to the nearest full share) determined by multiplying (i) the number of Company Common Shares subject to the Company Unvested Stock Option immediately prior to the Effective Time by (ii) the Conversion Ratio (as hereinafter defined), at an exercise price per Parent Common Share (rounded up to the nearest tenth of a cent) equal to the exercise price per Company Common Share immediately prior to the Effective Time divided by the Conversion Ratio. Parent shall pay cash to holders of Company Unvested Stock Options in lieu of issuing fractional shares of Parent Common Shares upon the exercise of Substitute Options for shares of Parent Common Shares. After the Effective Time, except as provided above in this Section 5.4, each Substitute Option shall be exercisable upon the same terms and conditions as were applicable under the related Company Unvested Stock Option immediately prior to or at the Effective Time. It is intended that (x) each Substitute Option shall qualify following the Effective Time as an incentive stock option (as defined in Section 422 of the Code) to the extent the related Company Unvested Stock Option qualified as an incentive stock option immediately prior to the Effective Time, and (y) the conversion of the Company Unvested Stock Options into Substitute Options shall not be treated as a modification, grant of a new option, or a change in the form of payment for purposes of Section 409A of the Code, and, in each case, the provisions of this Section 5.4(b) shall be applied consistently with such intention; provided, that none of Parent, Sub, the Company or any of their respective agents, Affiliates or employees shall be deemed to have made any representation or warranty or shall have any responsibility or liability with respect to the Tax consequences of the conversion of the Company Stock Options hereunder. The Company shall take all necessary action to implement

the provisions of this Section 5.4. As soon as reasonably practicable, Parent shall file a registration statement on Form S-8 (or any successor or other appropriate form) with respect to Parent Common Shares subject to such Substitute Options, or shall cause such Substitute Options to be deemed to be issued pursuant to a Parent stock plan for which shares of Parent Common Shares have been previously registered pursuant to an appropriate registration form.

(c) For purposes of this Section 5.4, the “Conversion Ratio” shall be a ratio, the numerator of which is the Common Per Share Consideration, and the denominator of which is the closing price of a Parent Common Share on The Nasdaq Stock Market LLC for the five (5) consecutive trading days immediately prior to the Effective Time.

Section 5.5 Commercially Reasonable Efforts.

(a) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other transactions contemplated by this Agreement, including: (i) obtaining all necessary actions or non-actions, waivers, consents and approvals from all Governmental Entities and making of all necessary registrations and filings (including filings with Governmental Entities) and taking of all reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entity (including those in connection with State Takeover Approvals), (ii) obtaining all necessary consents, approvals or waivers from third parties, and (iii) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by this Agreement. No party to this Agreement shall consent to any voluntary delay of the consummation of the Merger at the behest of any Governmental Entity without the consent of the other parties to this Agreement, which consent shall not be unreasonably withheld. The parties shall file an initial filing pursuant to the HSR Act as soon as practicable following the date hereof.

The Company and Parent agree to cooperate with the other in the filing of any returns with respect to the Gains Taxes, including supplying in a timely manner a complete list of all real property interests held by the Company and any of its Subsidiaries and any information with respect to such property that is reasonably necessary to complete such returns. The portion of the consideration allocable to the real property of the Company and any of its Subsidiaries shall be determined by Parent in its reasonable discretion.

(d) by either Parent or the Company if: (i) the Merger has not been effected on or prior to the close of business on February 17, 2010; provided, however, that the right to terminate this Agreement pursuant to this Section 7.1(d)(i) shall not be available to any party whose failure to fulfill any of its obligations contained in this Agreement has been the cause of, or resulted in, the failure of the Merger to have occurred on or prior to the aforesaid date or (ii) any court or other Governmental Entity having jurisdiction over a party hereto shall have issued an order, decree or ruling or taken any other action permanently enjoining, restraining or otherwise prohibiting the transactions contemplated by this Agreement and such order, decree, ruling or other action shall have become final and nonappealable; or

(e) by Parent (x) if the holders of a majority of the outstanding Company Common Shares and Company Preferred Shares, voting together as a single class, do not approve this Agreement or if the holders of a majority of the outstanding Company Preferred Shares, voting together as a single class, do not approve this Agreement or (y) if the Company fails to provide Parent with evidence to such effect, in each case no later than ten (10) days following the date hereof.

(a) The Indemnity Fund shall be available to indemnify, hold harmless and reimburse any Parent Group Member (as hereinafter defined) from any Loss or Expense indemnifiable under Section 8.2(a) and as provided in the Indemnity Agreement.

(b) Nothing in this Agreement shall limit the liability of the Company for any breach of any representation, warranty or covenant contained in this Agreement if it shall be terminated; provided, that, notwithstanding anything to the contrary herein, resort to the Indemnity Fund shall be the exclusive remedy of the Parent Group Members for any Loss or Expense following the Effective Time other than for fraud, intentional misrepresentation or as set forth in Section 8.2(b).

Section 8.2 Indemnification from Indemnity Fund.

(a) From and after the Effective Time, each Parent Group Member shall be indemnified, held harmless and reimbursed from the Indemnity Fund from and against any and all Loss and Expense incurred by such Parent Group Member in connection with or arising from:

(i) any breach or failure to perform by the Company of any of its agreements, covenants or obligations in this Agreement; or

(ii) any breach of any warranty or the inaccuracy of any representation of the Company contained in this Agreement or any certificate delivered by or on behalf of the Company pursuant to this Agreement.

Further, each Parent Group Member shall be indemnified, held harmless and reimbursed from the Indemnity Fund from and against any and all Loss and Expense incurred by the Company, Parent or the Surviving Corporation in connection with or arising from Dissenting Shares as contemplated by Section 1.5(f);

provided, however, that the Parent Group Members shall only be entitled to indemnification, and the Indemnity Fund shall be used to indemnify and hold harmless hereunder, with respect to the matters set forth in clause (ii) of this Section 8.2(a) (other than Sections 3.1, 3.2, 3.3, 3.8, 3.14, the certificate delivered pursuant to Section 6.3(a) to the extent it relates to such Sections and the other certificates delivered pursuant to Section 6.3, as to which this proviso shall not apply) only in the event that the aggregate amount (without duplication) of Loss and Expense borne by the Parent Group Members with respect thereto exceeds $500,000; provided, further, that the indemnification of the Parent Group Members from the Indemnity Fund under clause (ii) of this Section 8.2(a) with respect to Section 3.14(i) and Section 3.14(m) shall be limited to $14,400,000 in the aggregate. Any payment pursuant to this Section 8.2(a) shall be made in the form of a transfer from the Indemnity Fund to the applicable Parent Group Member(s) pursuant

to the Indemnity Agreement. The Company Stockholders shall not have any right of contribution from the Surviving Corporation with respect to any Loss or Expense claimed by any Parent Group Member after the Effective Time.

(b) From and after the Effective Time, each Parent Group Member shall be indemnified, held harmless and reimbursed by the Company Stockholders and the Company Vested Stock Optionholders from and against all Loss and Expense incurred by such Parent Group Member in connection with or arising from any breach of any warranty and the inaccuracy of any representation of the Company contained in Sections 3.2, 3.3 or 3.8 of this Agreement or any certificates delivered by or on behalf of the Company pursuant to this Agreement to the extent relating to such sections (collectively, the “Specified Representations”). The Parent Group Members shall be indemnified from the Indemnity Fund until funds are no longer available thereunder for such indemnification before they shall be indemnified by the Company Stockholders and the Company Vested Stock Optionholders pursuant to this Section 8.2(b). The liability of each Company Stockholder and Company Vested Stock Optionholder under this Section 8.2(b) shall be limited to fifty percent (50%) of the portion of the Aggregate Merger Consideration received by such Company Stockholder or Company Vested Stock Optionholder; provided, that the liability of each Company Stockholder and Company Vested Stock Optionholder under this Section 8.2(b) with respect to the Specified Representations relating to Section 3.2 (Capitalization) of this Agreement shall be limited to one hundred percent (100%) of the portion of the Aggregate Merger Consideration received by such Company Stockholder or Company Vested Stock Optionholder. The liability of the Company Stockholders and the Company Vested Stock Optionholders under this Section 8.2(b) shall be several and not joint. No claim shall be made for any Loss related to or arising from (A) the value or condition of any Tax asset (e.g., net operating loss carryforward or tax credit carryforward) of the Company or any of its Subsidiaries or (B) the ability of Parent, the Surviving Corporation or their Affiliates to utilize such Tax asset for any taxable period commencing after the Effective Time.

(c) As used in this Agreement, (i) “Expense” means any and all expenses incurred in connection with investigating, defending or asserting any claim, action, suit or proceeding incident to any matter indemnified against hereunder (including court filing fees, court costs, arbitration fees or costs, witness fees and reasonable fees and disbursements of legal counsel, investigators, expert witnesses, consultants, accountants and other professionals), (ii) “Loss” means any and all losses, costs, liabilities, settlement payments, awards, judgments, fines, penalties, damages, expenses, deficiencies or other charges; provided, that such amounts shall be reduced by any amount for which the Parent Group Members actually receive reimbursement from any insurance carrier (excluding any self insurance maintained by the Parent or any of its Affiliates) and shall take into account Taxes imposed on, and any Tax benefit actually received by, a Parent Group Member, in each case as a result of such Loss (including as a result of the receipt of any indemnification payment), and (iii) “Parent Group Members” means Parent and its Affiliates and their respective successors and assigns, including, after the Effective Time, the Surviving Corporation.

(d) The indemnification provided for in Section 8.2(a) shall terminate on the first (1^st) anniversary of the Effective Time (and no claims shall be made by any Parent Group Member under Section 8.2(a) thereafter), except that such indemnification shall continue as to

any Loss or Expense in connection with which a Claim Notice (as hereinafter defined) is given in accordance with the requirements of Section 8.4 on or prior to the date such indemnification obligation would otherwise terminate in accordance with this Section 8.2, as to which the indemnification obligation hereunder shall continue until the liability to be satisfied from the Indemnity Fund shall have been determined pursuant to this Article VIII and all Parent Group Members shall have been reimbursed out of the Indemnity Fund for such Loss or Expense in accordance with the terms hereof.

Section 8.3 Termination of Indemnity Fund. Upon termination of the indemnification obligations under this Article VIII and reimbursement of the Parent Group Members of Losses and Expenses payable in respect thereof hereunder, the Indemnity Fund shall terminate and shall be distributed in accordance with the Indemnity Agreement after payment of any amounts therefrom due to the Indemnity Agent.

Section 8.4 Notice and Determination of Indemnity Fund Claims.

(a) If any Parent Group Member wishes to make a claim for indemnification to be satisfied from the Indemnity Fund, such Parent Group Member (individually or collectively, the “Claiming Party”) shall so notify the Parent and the Stockholders Representative in writing (the “Indemnity Fund Claim Notice”) of the facts giving rise to such claim for indemnification hereunder. Such Indemnity Fund Claim Notice shall describe in reasonable detail (to the extent then known) the Loss or Expense and the method of computation of such Loss or Expense and contain a reference to the provisions of this Agreement in respect of which such Loss or Expense shall have occurred. The Indemnity Fund Claim Notice shall be attached to a written notice delivered by Parent to the Indemnity Agent (the “Parent Claim Notice”).

(b) Unless the Stockholders Representative shall have delivered an Indemnity Fund Objection (as hereinafter defined) to Parent and the Indemnity Agent in accordance with Section 8.4(c), the Indemnity Agent shall, on the thirtieth (30^th) day (or such earlier day as Parent and the Stockholders Representative shall authorize in writing to the Indemnity Agent) after receipt of a Parent Claim Notice with respect to indemnification for a specified amount, deliver to Parent, for its account or for the account of each Parent Group Member as set forth in the Indemnity Fund Claim Notice attached to the Parent Claim Notice, such portion of the Indemnity Fund, valued in accordance with the Indemnity Agreement, with a value equal to the specified amount.

(c) Until the thirtieth (30^th) day following delivery of the Parent Claim Notice to the Indemnity Agent, the Stockholders Representative may deliver to the Indemnity Agent and Parent a written objection (an “Indemnity Fund Objection”) to the claim made in such Indemnity Fund Claim Notice and attached to the Parent Claim Notice. At the time of delivery of any Indemnity Fund Objection to Parent and the Indemnity Agent, a duplicate copy of such Indemnity Fund Objection shall be delivered to the Claiming Party.

(d) Upon receipt of an Indemnity Fund Objection properly made, the Indemnity Agent shall (i) deliver to Parent, for its account or for the account of each Parent Group Member as set forth in the Indemnity Fund Claim Notice attached to the Parent Claim Notice, such portion of the Indemnity Fund, valued in accordance with the Indemnity

Agreement, with a value equal to that portion of the amount subject to the Indemnity Fund Claim Notice, if any, which is not disputed by the Stockholders Representative and (ii) designate in the Indemnity Fund a portion thereof, valued in accordance with the Indemnity Agreement, with a value equal to the amount subject to the Indemnity Fund Claim Notice which is disputed by the Stockholders Representative. Thereafter, the Indemnity Agent shall not dispose of such designated portion of the Indemnity Fund until the Indemnity Agent shall have received a certified copy of the final decision of the arbitrators as contemplated by Section 8.6, or the Indemnity Agent shall have received a copy of the written agreement between Parent and the Stockholders Representative resolving such dispute and setting forth the amount, if any, which the Claiming Party is entitled to receive. The Indemnity Agent will deliver to Parent, for its account or for the account of each Parent Group Member entitled to payment, such portion of the Indemnity Fund, valued in accordance with the Indemnity Agreement, with a value equal to the amount that the Claiming Party is entitled to receive as set forth in the arbitration decision after the expiration of ten (10) business days from the receipt of such decision or, in the event that the amount to which the Claiming Party is entitled is established pursuant to an agreement between the Parent and the Stockholders Representative (and the Claiming Party, if applicable), promptly after the Indemnity Agent’s receipt of such agreement.

Section 8.5 Notice and Determination of Stockholder Claims.

(a) If the Claiming Party wishes to make a claim for indemnification to be satisfied from Company Stockholders and Company Vested Stock Optionholders pursuant to Section 8.2(b), such Claiming Party shall so notify each Company Stockholder and Company Vested Stock Optionholder from whom it is seeking indemnification (the “Affected Stockholder”) in writing (the “Stockholder Claim Notice”, and together the Indemnity Fund Notice, the “Claim Notices”, and each a “Claim Notice”) of the facts giving rise to such claim for indemnification hereunder. Such Stockholder Claim Notice shall describe in reasonable detail (to the extent then known) the Loss or Expense and the method of computation of such Loss or Expense and contain a reference to the Specified Representation in respect of which such Loss or Expense shall have occurred. If the Claiming Party is not Parent, the Stockholder Claim Notice must be accompanied by a certificate from Parent confirming that the Claiming Party is a Parent Group Member.

(b) Unless the Affected Stockholder shall have delivered a Stockholder Objection in accordance with Section 8.5(c), the Affected Stockholder shall, on the thirtieth (30^th) day (or such earlier day as the Affected Stockholder may determine) after receipt of a Stockholder Claim Notice with respect to indemnification for a specified amount, deliver to Parent, for its account or for the account of each Parent Group Member named in the Stockholder Claim Notice, payment of the specified amount in cash via check made payable to Parent or wire transfer to an account to be designated by Parent.

(c) Until the thirtieth (30^th) day following delivery of an Stockholder Claim Notice, the Affected Stockholder may deliver to the Claiming Party a written objection (a “Stockholder Objection”, together with the Indemnity Fund Objection, the “Objections”, and each an “Objection”) to the claim made in such Stockholder Claim Notice.

(d) Upon receipt of a Stockholder Objection properly made, the Affected

Stockholder shall deliver to Parent, for its account or for the account of each Parent Group Member named in the Stockholder Claim Notice, such portion of the specified indemnification amount, if any, which is not disputed by the Affected Stockholder. Thereafter, after the expiration of ten (10) business days from the receipt of a certified copy of the final decision of the arbitrators as contemplated by Section 8.6 setting forth the amount, if any, which such Claiming Party is entitled to receive, or promptly upon the completion of the memorandum setting forth the agreement of the Claiming Party and the Affected Stockholder as contemplated by Section 8.6 and the specified amount, if any, that the Claiming Party shall be entitled to receive, the Affected Stockholder shall deliver to Parent, for its account or for the account of each Parent Group Member entitled to payment, the specified amount in cash via check made payable to Parent or wire transfer to an account to be designated by Parent.

Section 8.6 Resolution of Conflicts; Arbitration.

(a) For claims made pursuant to Section 8.4, the Claiming Party shall deliver a written response to the Stockholders Representative in respect of any Indemnity Fund Objection properly delivered by the Stockholders Representative. If after twenty (20) days following delivery of such response there remains a dispute as to any claims, the Stockholders Representative and the Claiming Party shall attempt in good faith for sixty (60) days to agree upon the rights of the respective parties with respect to each of such claims. If the Stockholders Representative and the Claiming Party should so agree, a memorandum setting forth such agreement shall be prepared and signed by both, and shall be furnished to the Indemnity Agent. The Indemnity Agent shall be entitled to rely on any such memorandum and shall distribute the applicable portion of Indemnity Fund in accordance with the terms thereof.

(b) If no such agreement can be reached after good faith negotiation, either the Claiming Party or the Stockholders Representative may, by written notice to the other, demand arbitration of the matter unless the amount of the Loss or Expense is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators. Within fifteen (15) days after such written notice is sent, Parent and the Stockholders Representative shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator. The decision of the arbitrators as to the validity and amount of any claim submitted thereto shall be binding, and conclusive on Parent, the Stockholders Representative, the Company Stockholders and the Company Vested Stock Optionholders, including with respect to claims for indemnification under Section 8.2(b). Notwithstanding anything in this Section 8.6, the Indemnity Agent shall be entitled to act in accordance with such decision and make or withhold payments out of the Indemnity Fund in accordance therewith.

(c) For claims made pursuant to Section 8.5, the Claiming Party shall deliver a written response to the Affected Stockholder in respect of any Stockholder Objection properly delivered by the Affected Stockholder. If after twenty (20) days following delivery of such response there remains a dispute as to any claims, the Affected Stockholder and the Claiming Party shall attempt in good faith for sixty (60) days to agree upon the rights of the respective parties with respect to each of such claims. If the Affected Stockholder and the Claiming Party should so agree, a memorandum setting forth such agreement shall be prepared and signed by

both and the Affected Stockholder shall pay the agreed upon amount to the Claiming Party.

(d) If no such agreement can be reached after good faith negotiation, the Claiming Party may, by written notice to the Affected Stockholder, demand arbitration of the matter unless the amount of the Loss or Expense is at issue in pending litigation with a third party, in which event arbitration shall not be commenced until such amount is ascertained or both parties agree to arbitration; and in either such event the matter shall be settled by arbitration conducted by three arbitrators. The Claiming Party may include in such arbitration some or all of the other Affected Stockholders to which any Claiming Party shall have submitted Claim Notices. The arbitrators shall be the same persons who shall have served or are serving as arbitrators pursuant to Section 8.6(b), provided, that if arbitrators shall have not been appointed pursuant to Section 8.6(b) or any of them is unwilling or unable to so serve, then within fifteen (15) days after such written notice is sent, Parent and a majority of the Affected Stockholders shall each select one arbitrator, and the two arbitrators so selected shall select a third arbitrator. The decision of the arbitrators as to the validity and amount of any claim submitted thereto shall be binding, and conclusive on Parent, the Company Stockholders and the Company Vested Stock Optionholders.

(e) Judgment upon any award rendered by the arbitrators may be entered in any court having jurisdiction. Any such arbitration shall be held in Los Angeles, California under the commercial rules then in effect of the American Arbitration Association. The non-prevailing party to an arbitration shall pay its own expenses, the fees of each arbitrator, the administrative fee of the American Arbitration Association, and the expenses, including attorneys’ fees and costs, reasonably incurred by the other party to the arbitration.

Section 8.7 Stockholders Representative.

(a) The “Stockholders Representative” shall be ▇▇▇▇▇▇ ▇▇▇▇, who may be replaced by the Company prior to the Effective Time. The Stockholders Representative shall be constituted and appointed as agent and attorney-in-fact for and on behalf of each of the Company Stockholders and the Company Vested Stock Optionholders receiving consideration pursuant to Article I. The Stockholders Representative shall have full power and authority to represent all such Company Stockholders and Company Vested Stock Optionholders and their respective successors with respect to all matters arising under this Agreement and the Indemnity Agreement and all actions taken by the Stockholders Representative hereunder and thereunder shall be binding upon all such Company Stockholders and Company Vested Stock Optionholders and their respective successors as if expressly confirmed and ratified in writing by each of them. The Stockholders Representative shall take any and all actions which it believes is necessary or appropriate under this Agreement and the Indemnity Agreement for and on behalf of such Company Stockholders and Company Vested Stock Optionholders, as fully as if the Company Stockholders and the Company Vested Stock Optionholders were acting on their own behalf, including, without limitation, defending all indemnity claims pursuant to Section 8.2, consenting to, compromising or settling all such indemnity claims, conducting negotiations with Parent and the Indemnity Agent under this Agreement and the Indemnity Agreement, taking any and all other actions specified in or contemplated by this Agreement and the Indemnity Agreement, and engaging counsel, accountants or other Stockholders Representatives in connection with the foregoing matters. Without limiting the generality of the foregoing, the Stockholders

Representative shall have full power and authority to interpret all the terms and provisions of this Agreement and the Indemnity Agreement and to consent to any amendment hereof or thereof on behalf of all such Company Stockholders and Company Vested Stock Optionholders and such successors. The Person designated to serve as the Stockholders Representative may be changed by the holders of a majority in interest of the Indemnity Fund from time to time upon not less than ten (10) days prior written notice to Parent. No bond shall be required of the Stockholders Representative, and the Stockholders Representative shall receive no compensation for services. Any expenses incurred by the Stockholders Representative in connection with its services hereunder shall be reimbursed from the Indemnity Fund upon presentation of appropriate expense documentation as and to the extent expressly provided in the Indemnity Agreement.

(b) The Stockholders Representative shall not be liable to the Company Stockholders or the Company Vested Stock Optionholders for any act done or omitted hereunder or under the Indemnity Agreement as Stockholders Representative while acting in good faith and in the exercise of reasonable judgment, and any act done or omitted pursuant to the written advice of counsel shall be conclusive evidence of such good faith. The Company Stockholders and the Company Vested Stock Optionholders shall severally indemnify the Stockholders Representative and hold it harmless from and against any loss, liability or expense incurred without gross negligence or bad faith on the part of the Stockholders Representative and arising out of or in connection with the acceptance and administration of its duties hereunder.

(c) The Stockholders Representative shall treat confidentially and not disclose any nonpublic information from or about the Company to anyone (except on a need to know basis to individuals who agree to treat such information confidentially).

Section 8.8 Actions of the Stockholders Representative. A decision, act, consent or instruction of the Stockholders Representative shall constitute a decision of all Company Stockholders and Company Vested Stock Optionholders to whom funds otherwise payable are deposited in the Indemnity Fund and shall be final, binding and conclusive upon each such Company Stockholder and Company Vested Stock Optionholder, and the Indemnity Agent and Parent may rely upon any decision, act, consent or instruction of the Stockholders Representative as being the decision, act, consent or instruction of each and every such Company Stockholder and Company Vested Stock Optionholder. The Indemnity Agent and each Parent Group Member are hereby relieved from any liability to any Person for any acts done by them in accordance with such decision, act, consent or instruction of the Stockholders Representative.

Section 8.9 Third-Party Claims. In the event Parent determines to make a demand against the Indemnity Fund with respect to a third party claim, Parent shall notify the Stockholders Representative of such claim, and the Stockholders Representative shall be entitled, at its expense, to participate in any defense of such claim. Parent shall have the right in its sole discretion to settle any such claim; provided, however, that Parent may not effect the settlement of any such claims without the consent of the Stockholders Representative, which consent shall not be unreasonably withheld. In the event that the Stockholders Representative has consented to any such settlement, the Stockholders Representative shall have no power or authority to object under Sections 8.4 or 8.5 or any other provision of this Article VIII to the amount paid in such settlement.

Section 8.10 Indemnification.

(a) Parent will, or will cause the Surviving Corporation to, fulfill and honor in all respects the obligations of the Company pursuant to (i) each indemnification agreement listed in Section 8.10 of the Company Letter in effect between the Company and each person who is a director or officer of the Company immediately prior to the Effective Time in each case the extent such agreement was delivered to Parent prior to the date hereof and (ii) any indemnification provision under the Company Charter or the Company Bylaws as in effect on the date of this Agreement (the persons to be indemnified pursuant to the agreements and provisions referred to in clauses (i) and (ii) of this Section 8.10(a) shall be referred to as, collectively, the “Company Indemnified Parties”).

(b) The provisions of this Section 8.10 are intended to be for the benefit of, and shall be enforceable by, each of the Company Indemnified Parties and their heirs and estates and such provisions may not be terminated or amended in any manner adverse to the interests of such Person without his or her prior consent. Notwithstanding anything herein to the contrary, if any claim, action, suit, proceeding or investigation is made against a Company Indemnified Party, for which such Company Indemnified Party is entitled to indemnification hereunder, on or prior to the sixth anniversary of the Effective Time, the provisions of this Section 8.10 shall continue in effect, solely with respect to such matters, until the final disposition of such claim, action, suit, proceeding or investigation.

(ii) that during the Noncompetition Period, Stockholder will not induce or attempt to persuade any employee, agent, licensor, content provider, supplier, distributor or customer of the Packet Core Business to terminate such employment, agency or business relationship in order to enter into any such relationship on behalf of any other business organization; provided, however, that general advertisements and job listings disseminated to the public at large will not be deemed to constitute a “solicitation” of employees pursuant to the foregoing provision.

In the event Stockholder’s employment is involuntarily terminated by the Company without Cause or Stockholder voluntarily terminates his employment from the Company with Good Reason and Stockholder does not at any time prior to the expiration of the Noncompetition Period breach this Agreement or any proprietary information, inventions or similar agreement between Stockholder and the Company or Parent, the Company will continue to pay Stockholder’s base salary, as in effect immediately prior to such termination, for the remainder of the Noncompetition Period; provided that the Company’s obligation to make such payments shall cease if Parent, in its sole discretion, provides Stockholder with written notice that it has elected to waive the restrictions hereunder. If Stockholder is a “specified employee,” as defined in Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), as of the date of Stockholder’s separation from service, then to the extent any amount payable to Stockholder hereunder (i) constitutes the payment of nonqualified deferred compensation, within the meaning of Section 409A of the Code, and (ii) under the terms of this Agreement would be payable prior to the six-month anniversary of Stockholder’s separation from service, such payment shall be delayed until the earlier to occur of (a) the six-month anniversary of Stockholder’s separation from service and (b) the date of Stockholder’s death.

A-3

a felony under federal or state law, (B) breach of or willful failure to perform any material covenants under a proprietary information and inventions agreement with the Company or its affiliates, (C) repeated refusal to perform the duties assigned by the Company or any of its affiliates, provided such duties are reasonably consistent with Stockholder’s employment position, (D) gross negligence or willful misconduct resulting in a material loss to the Company or any of its affiliates, or damage to the reputation of the Company or any of its affiliates, (E) material violation of the employment policies of the Company or any of its affiliates or (F) violation of any statutory or common law duty of loyalty to the Company or any of its affiliates.

For purposes of this Section 1(f), “Good Reason” shall exist upon the occurrence, without Stockholder’s express written consent, of any of the following events: (A) a material diminution in Stockholder’s position, authority or duties (including the assignment to Stockholder of any duties materially and adversely inconsistent with Stockholder’s position, authority or duties hereunder) as in effect immediately following the Effective Time; (B) a reduction of more than 5% (other than pursuant to a uniform reduction applicable to other similarly situated employees of the Company) in the base salary of Stockholder; or (C) relocation of the Company’s business office to any location more than 30 miles from its location as of the Effective Time; provided, however, that the occurrence of any such event shall not constitute Good Reason unless Stockholder provides written notice to Stockholder’s direct supervisor or the senior human resources representative of Parent of the existence of such event not later than 90 days after the initial existence of such event, and the Company shall have failed to remedy such event within 30 days after receipt of such notice.

Nothing contained in this paragraph shall limit or otherwise affect any obligation of Stockholder under any employment agreement, including any proprietary information, inventions or similar agreement, entered into with the Company or Parent. In addition, nothing contained herein shall limit or otherwise affect the ability of Stockholder to own not more than 1% of the outstanding capital stock of any entity that is engaged in the Packet Core Business provided that either such investment is a passive investment in a publicly traded company or Stockholder receives such stock pursuant to one or more equity-based compensation awards granted solely in connection with his services for a non-Competitive Division and Stockholder is not directly or indirectly involved in the management or operation of such business or otherwise providing consulting services to such business, except to the extent Stockholder is permitted to perform services for a non-Competitive Division, as set forth above.]¹

(g) Prior to the Effective Time, the Stockholder will duly exercise any Company Vested Stock Options held by such Stockholder in accordance with its terms.

(h) The Stockholder will not exercise any dissenters’ rights or rights of appraisal under applicable law with respect to the Merger, the Merger Agreement and the transactions contemplated thereby.

2. Release. Effective at the Effective Time, the Stockholder does hereby fully, finally and irrevocably release, acquit and forever discharge the Company, and its current, former and future members, managers, trustees, representatives, employees, principals, agents, affiliates, successors, assigns, beneficiaries, heirs, executors, personal or legal representatives, accountants, administrators, insurers and attorneys of any of them (collectively, the “Released Parties”) from any and all commitments, agreements, contracts, undertakings, actions, debts, claims, counterclaims, suits, causes of action, damages, demands, liabilities, obligations, costs, expenses and compensation of every kind and nature whatsoever, past, present or future, at law or in equity, whether known or unknown, contingent or otherwise, which the Stockholder had, have, or may have had at any time in the past until and including the Effective Time against the Released Parties, or any of them, which relate to or arise out of the Stockholder’s prior relationship with the Company or its rights or status as a stockholder of the Company, in each case except (i) as expressly provided in this Agreement, (ii) as expressly provided in the Merger Agreement (including the rights of indemnification contained in Section 8.10 thereof), and (iii) the undersigned’s right to receive unpaid wages or accrued benefits as of the date hereof in connection with his employment, if any, by the Company.

3. Representations and Warranties. The Stockholder represents and warrants to Parent as follows:

(a) The Stockholder is the record and beneficial owner of, and has good title to, the Subject Shares. The Stockholder does not own, of record or beneficially, any shares of capital stock of the Company other than the Subject Shares. The Stockholder has the sole right to vote, and the sole power of disposition with respect to, the Subject Shares, and except for that certain Third Amended and Restated Voting Agreement, dated as of October 9, 2008, none of the Subject Shares is subject to any voting trust, proxy or other agreement, arrangement or restriction with respect to the voting or disposition of such Subject Shares, except as contemplated by this Agreement. The Stockholder holds the Company Stock Options appearing on the signature page hereof.

(b) This Agreement has been duly executed and delivered by the Stockholder. Assuming the due authorization, execution and delivery of this Agreement by Parent, this Agreement constitutes the valid and binding agreement of the Stockholder enforceable against the Stockholder in accordance with its terms, except as may be limited by applicable bankruptcy, insolvency, reorganization, moratorium and other similar laws of general application which may affect the enforcement of creditors’ rights generally and by general equitable principles. The execution and delivery of this Agreement by the Stockholder does not and will not conflict with any agreement, order or other instrument binding upon the Stockholder, nor require the Stockholder to make or obtain any regulatory filing or approval.

(c) The Stockholder understands and acknowledges that it may hereafter discover facts and legal theories concerning this Agreement (including without limitation Section 2) and the subject matter hereof in addition to or different from those which it now believes to be true. The Stockholder understands and hereby agrees that this Agreement (including without limitation, Section 2) shall remain effective in all respects notwithstanding those additional or different facts and legal theories or the discovery of those additional or different facts or legal theories. The Stockholder assumes the risk of

A-5

any mistake of fact or law with regard to any potential claim or with regard to any of the facts which are now unknown to it relating thereto. Further, in entering into this Agreement, the Stockholder acknowledges and agrees that it is not relying upon any information provided by Parent or Sub in connection with the provisions of this Agreement.

4. Termination. The obligations of the Stockholder hereunder shall terminate in the event the Merger Agreement is terminated pursuant to Section 7.1 thereof. This Agreement shall continue in effect and survive after the Effective Time. No termination of this Agreement shall relieve the Stockholder from any liability in connection with this Agreement incurred prior to such termination.

5. Further Assurances. The Stockholder will, from time to time, execute and deliver, or cause to be executed and delivered, such additional or further consents, documents and other instruments as Parent may reasonably request for the purpose of effectively carrying out the transactions contemplated by this Agreement.

6. Successors, Assigns and Transferees Bound. Any successor, assignee or transferee (including a successor, assignee or transferee as a result of the death of the Stockholder, such as an executor or heir) shall be bound by the terms hereof, and the Stockholder shall take any and all actions necessary to obtain the written confirmation from such successor, assignee or transferee that it is bound by the terms hereof.

7. Remedies. The Stockholder acknowledges that money damages would be both incalculable and an insufficient remedy for any breach of this Agreement by it and that any such breach would cause Parent irreparable harm. Accordingly, the Stockholder agrees that in the event of any breach or threatened breach of this Agreement, Parent, in addition to any other remedies at law or in equity it may have, shall be entitled, without the requirement of posting a bond or other security, to equitable relief, including injunctive relief and specific performance.

8. Severability. Notwithstanding anything else to the contrary in this Agreement, it is the intent and understanding of each party hereto that if, in any action before any court or tribunal legally empowered to enforce this Agreement, any term, restriction, covenant or promise in this Agreement is found to be unreasonable and for that reason unenforceable, then such term, restriction, covenant or promise shall be deemed modified to the extent necessary to make it enforceable by such court or agency.

9. Amendment. This Agreement may be amended only by means of a written instrument executed and delivered by both the Stockholder and Parent.

10. Governing Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof.

11. Capitalized Terms. Capitalized terms used in this Agreement that are not defined herein shall have such meanings as set forth in the Merger Agreement.

12. Interpretation. When a reference is made in this Agreement to a Section or an Article, such reference shall be to a Section or an Article of this Agreement unless

A-6

otherwise indicated. The section headings contained in Indemnity Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of Indemnity Agreement. For purposes of this Agreement, the words “herein,” “hereof,” “hereby,” “hereto” and “hereunder” refer to this Agreement as a whole. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neutral genders of such term.

13. Counterparts. This Agreement may be executed in counterparts, all of which shall be considered one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties.

14. No Limitation on Actions of the Stockholder as Director. In the event the Stockholder is a director of the Company, notwithstanding anything to the contrary in this Agreement, nothing in this Agreement is intended or shall be construed to require the Stockholder to take or in any way limit any action that the Stockholder may take to discharge the Stockholder’s fiduciary duties as a director of the Company.

WHEREAS, under the Merger Agreement all Parent Group Members (as defined in the Merger Agreement) shall be indemnified, held harmless and reimbursed as provided in Article VIII of the Merger Agreement;

WHEREAS, to ensure that funds will be available to indemnify, hold harmless and reimburse the Parent Group Members as required by Article VIII of the Merger Agreement, the Merger Agreement provides that in connection with the Merger, promptly after the Effective Time (as hereinafter defined) $18 million (the “Indemnity Amount”) shall be deposited with the Indemnity Agent in an escrow account established pursuant to this Indemnity Agreement and held and subsequently disbursed in accordance with the terms of this Indemnity Agreement (such Indemnity Amount, together with any earnings thereon being herein collectively referred to as the “Indemnity Fund”).

WHEREAS, the Merger Agreement provides for the Stockholders Representative to act in accordance herewith in connection with this Indemnity Agreement and the indemnification obligations contained in the Merger Agreement; and

WHEREAS, the Indemnity Agent has agreed to hold the Indemnity Fund pursuant to the terms of this Indemnity Agreement;

NOW, THEREFORE, in consideration of the mutual promises and covenants herein contained, the parties hereto agree as follows:

Section 2. Deposit and Use of Indemnity Amount.

Promptly after the Certificate of Merger (as defined in the Merger Agreement) is accepted for recording or such later time as established by the Certificate of Merger (the “Effective Time”), the Indemnity Amount shall be deposited by Parent in an escrow account with the Indemnity Agent (the “Account”).

Immediately after receipt from Parent of the Indemnity Amount, the Indemnity Agent shall confirm to the Parent and the Stockholders Representative such receipt in writing in accordance with Section 13 of this Indemnity Agreement.

The Indemnity Agent agrees to hold, pay and disburse the Indemnity Fund and to act as Indemnity Agent in accordance with the terms, conditions and provisions of this Indemnity Agreement.

Section 3. Disposition of Indemnity Amount.

The Parties may instruct the Indemnity Agent to disburse to Parent or each Parent Group Member as it shall be entitled to receive payment from the Indemnity Fund in the amount which, at any time and from time to time, such Parent Group Member is entitled to be indemnified, reimbursed and held harmless from the Indemnity Fund as provided in Article VIII of the Merger Agreement (including, without limitation, Sections 8.4 and 8.6 thereof).

The Indemnity Agent shall not dispose of all or any portion of the Indemnity Fund other than as provided in this Indemnity Agreement.

Section 4. Payment.

If any Parent Group Member wishes to make a claim for indemnification to be satisfied from the Indemnity Fund, such Parent Group Member (individually or collectively, the “Claiming Party”) shall so notify the Parent and the Stockholders Representative in writing (the “Indemnity Fund Claim Notice”) of the facts giving rise to such claim for indemnification hereunder. Such Indemnity Fund Claim Notice shall describe in reasonable detail (to the extent then known) the Loss or Expense and the method of computation of such Loss or Expense and contain a reference to the provisions of this Indemnity Agreement in respect of which such Loss or Expense shall have occurred. The Indemnity Claim Notice shall be attached to a written notice delivered by Parent to the Indemnity Agent (the “Parent Claim Notice”).

Unless the Stockholders Representative shall have delivered an Indemnity Fund Objection to Parent and the Indemnity Agent in accordance with Section 4(c) of this Indemnity Agreement, the Indemnity Agent shall, on the thirtieth (30^th) day (or such earlier day as Parent and Stockholders Representative shall authorize in writing to the Indemnity Agent) after receipt of a Parent Claim Notice with respect to indemnification for a specified amount, deliver to Parent, for its account or for the account of each Parent Group Member as set forth in the Indemnity

B-2

Fund Claim Notice attached to the Parent Claim Notice, such portion of the Indemnity Fund, as valued by Parent, with a value equal to the specified amount.

Until the thirtieth (30^th) day following delivery of the Parent Claim Notice to the Indemnity Agent, the Stockholders Representative may deliver to the Indemnity Agent and Parent a written objection (an “Indemnity Fund Objection”) to the claim made in such Indemnity Fund Claim Notice and attached to the Parent Claim Notice. At the time of delivery of any Indemnity Fund Objection to Parent and the Indemnity Agent, a duplicate copy of such Indemnity Fund Objection shall be delivered to the Claiming Party.

Upon receipt of an Indemnity Fund Objection properly made, the Indemnity Agent shall (i) deliver to Parent, for its account or for the account of each Parent Group Member as set forth in the Indemnity Fund Claim Notice attached to the Parent Claim Notice, such portion of the Indemnity Fund, as valued by Parent, with a value equal to that portion of the amount subject to the Indemnity Fund Claim Notice, if any, which is not disputed by the Stockholders Representative and (ii) designate in the Indemnity Fund a portion thereof, valued in accordance with the Indemnity Agreement, with a value equal to the amount subject to the Indemnity Fund Claim Notice which is disputed by the Stockholders Representative. Thereafter, the Indemnity Agent shall not dispose of such designated portion of the Indemnity Fund until the Indemnity Agent shall have received a certified copy of the final decision of the arbitrators as contemplated by Section 8.6 of the Merger Agreement, or the Indemnity Agent shall have received a copy of the written agreement between the Parent and the Stockholders Representative resolving such dispute and setting forth the amount, if any, which the Claiming Party is entitled to receive. The Indemnity Agent will deliver to Parent, for its account or for the account of each Parent Group Member entitled to payment, such portion of the Indemnity Fund, as valued by Parent, with a value equal to the amount that the Claiming Party is entitled to receive as set forth in the arbitration decision after the expiration of ten (10) business days from the receipt of such decision or, in the event that the amount to which the Claiming Party is entitled is established pursuant to an agreement between the Parent Group Member, the Stockholders Representative (and the Claiming Party, if applicable), promptly after the Indemnity Agent’s receipt of such agreement.

Payments and deliveries pursuant to an Indemnity Fund Claim Notice shall be charged to and withdrawn from the Account unless the Indemnity Agent is restrained, enjoined or stayed by law or court order from withdrawing assets from the Account.

Section 5. Delivery of Indemnity Amount Upon Termination.

On the first (1^st ) anniversary of the Effective Time (the “Distribution Date”), the Indemnity Agent shall deliver to the Exchange Agent (or, if the agreement appointing the Exchange Agent shall then have terminated, to Parent) an amount (the “Distribution Amount”) equal to (A) the amount remaining in the Indemnity Fund, less (B) any amount designated as subject to a claim pursuant to such

B-3

Indemnity Fund Claim Notice to the extent such claim has not been resolved and paid prior to such date, and less (C) any amount previously designated in writing by the Stockholders Representative to the Indemnity Agent (with a copy delivered to Parent) as amounts that should be withheld to cover its expenses incurred in connection with its activities hereunder (to the extent the Indemnity Agent shall then have received written notice from the Stockholders Representative to such effect in accordance with Section 8(c). Upon its receipt of such Distribution Amount, the Exchange Agent or Parent, as the case may be, shall disburse the Distribution Amount to the applicable Company Stockholders and Company Vested Stock Optionholders on a pro rata basis based upon the “Indemnity Amount” reflected on Annex A; provided, that the Exchange Agent or Parent, as the case may be, shall not be required to deliver the applicable portion of the Distribution Amount to any Company Stockholder unless and until such Company Stockholder shall have delivered the applicable Certificates (or complied with Section 1.13 of the Merger Agreement in case such Certificates have been lost, stolen or destroyed), and Transmittal Letter as required by Section 1.6 of the Merger Agreement; provided, further, that the Exchange Agent or Parent, as the case may be, shall not be required to deliver the applicable portion of the Distribution Amount to any Company Vested Stock Optionholder unless and until such Company Vested Stock Optionholder shall have delivered the Transmittal Letter as required by Section 1.6 of the Merger Agreement.

Any amounts retained in the Account after the Distribution Date shall be held by the Indemnity Agent and shall first be used to indemnify the Parent Group Members, subject to the terms and conditions of this Indemnity Agreement, and upon resolution and payment out of the Indemnity Fund of all pending claims, any remaining amounts in the Account shall be transferred to the Stockholders Representative with respect to reasonable out-of-pocket expenses incurred by it in connection with its activities hereunder (to the extent the Indemnity Agent shall then have received written notice from the Stockholders Representative to such effect in accordance with Section 8(c) of this Indemnity Agreement), and any remaining amount shall be distributed to the Exchange Agent (or, if the agreement appointing the Exchange Agent shall then have terminated, to Parent), who shall disburse such portion in the manner set forth in Section 5(a) of this Indemnity Agreement.

Upon distribution of the entire amount of the Indemnity Fund, the Indemnity Agent shall give the Parent notice to such effect. Upon such distribution, this Indemnity Agreement shall be terminated.

At any time prior to final termination of this Indemnity Agreement, the Indemnity Agent shall, if so instructed in a writing signed by Parent and the Stockholders Representative, release from the Indemnity Fund to Parent or the Exchange Agent, as directed, the portion of the Indemnity Fund specified in such writing.

Section 6. Permitted Investments; Interest.

The Indemnity Agent is hereby authorized and directed to hold the Indemnity Fund in the Account and to disburse such Indemnity Fund only in accordance with the terms of this Indemnity Agreement. From the date hereof until the date of disbursement of the Indemnity Fund pursuant to Section 5(c) of this Indemnity Agreement, the Indemnity Agent is authorized and directed to invest and reinvest the Indemnity Fund in a JPMorgan Chase Bank N.A. money market deposit account (“MMDA”) or a successor or similar investment offered by the Indemnity Agent, unless otherwise instructed in writing by the Parties and as shall be acceptable to the Indemnity Agent (the “Permitted Investments”). The rate of return on an MMDA varies from time to time. Permitted Investments and interest accruing on, and any profit resulting from, such investments shall be added to, and become a part of, the Indemnity Fund pursuant to this Indemnity Agreement. Notwithstanding anything else to the contrary in this Indemnity Agreement, forty percent (40%) of such interest and profit earned prior to the Distribution Date shall be disbursed by the Indemnity Agent to the Company Stockholders and Company Vested Stock Optionholders on the Distribution Date in accordance with the information set forth in Annex A hereto (as further referenced in Section 9 of this Indemnity Agreement). For purposes of this Indemnity Agreement, “interest” on the Indemnity Fund shall include all proceeds thereof and investment earnings with respect thereto. The Indemnity Agent, Parent, the Surviving Corporation and the Stockholders Representative shall not be responsible for any unrealized profit or realized loss realized on such investments. The Parties recognize and agree that the Indemnity Agent will not provide supervision, recommendations or advice relating to either the investment of the Indemnity Fund or the purchase, sale, retention or other disposition of any investment described herein. The Indemnity Agent shall have the right to liquidate any investments held in order to provide funds necessary to make required payments under this Indemnity Agreement.

Section 7. Liability and Compensation of Indemnity Agent.

The duties and obligations of the Indemnity Agent hereunder shall be determined solely by the express provisions of this Indemnity Agreement, and no implied duties or obligations shall be read into this Indemnity Agreement against the Indemnity Agent. The Indemnity Agent shall, in determining its duties hereunder, be under no obligation to refer to any other documents between or among the Parties related in any way to this Indemnity Agreement (including but not limited to the Merger Agreement), it being specifically understood that the following provisions are accepted by the Parties and the Indemnity Agent. In the event of any conflict between the terms and provisions of this Indemnity Agreement, those of the Merger Agreement, any schedule or exhibit attached to this Indemnity Agreement, or any other agreement among the Parties, the terms and conditions of this Indemnity Agreement shall control. Parent shall indemnify and hold the Indemnity Agent harmless from and against any and all liability and expense which may arise out of any action taken or omitted by the Indemnity Agent in accordance with this Indemnity Agreement, except such liability and expense as may result from the gross negligence or willful misconduct of the Indemnity Agent. The reasonable costs and expenses of the Indemnity Agent to enforce its indemnification rights under this Section 7(a) shall also be paid by Parent. Parent shall be entitled to be reimbursed out of the Indemnity Fund for fifty percent

B-5

(50%) of any amount that Parent is required to pay to the Indemnity Agent pursuant to this Section 7(a), payable in the manner set forth in Section 4 hereof. The Indemnity Agent’s right to indemnification shall survive the termination of this Indemnity Agreement and removal or resignation of the Indemnity Agent. The Indemnity Agent agrees that it shall not settle or compromise any such claim to which it shall be entitled to indemnification without the consent of Parent, which consent shall not be unreasonably withheld or delayed.

The Indemnity Agent shall not be liable to any person by reason of any error of judgment or for any act done or step taken or omitted by it, or for any mistake of fact or law or anything which it may do or refrain from doing in connection herewith unless caused by or arising out of its own gross negligence or willful misconduct.

The Indemnity Agent shall be entitled to rely on, and shall be protected in acting in reliance upon, any instructions or directions furnished to it in writing signed by both Parent and the then Stockholders Representative pursuant to any provision of this Indemnity Agreement and shall be entitled to treat as genuine, and as the document it purports to be, any letter, paper or other document furnished to it or attached thereto and believed by the Indemnity Agent to be genuine and to have been signed and presented by the proper Party or Parties. In performing its obligations hereunder, the Indemnity Agent may consult with counsel to the Indemnity Agent and shall be entitled to rely on, and shall be protected in acting in reliance upon, the advice or opinion of such counsel.

The Indemnity Agent shall be entitled to its customary fee for the performance of services by the Indemnity Agent hereunder for each year or portion thereof that any portion of the Indemnity Fund remains in escrow and shall be reimbursed for reasonable costs and expenses incurred by it in connection with the performance of such services (such fees, costs and expenses are hereinafter referred to as the “Indemnity Agent’s Compensation”). The Indemnity Agent shall render statements to Parent setting forth in detail the Indemnity Agent’s Compensation and the basis upon which the Indemnity Agent’s Compensation was computed. The Indemnity Agent’s Compensation shall be paid by Parent. To the extent Indemnity Agent’s Compensation is not paid by Parent, the foregoing shall be paid from the Indemnity Fund after written notice from the Indemnity Agent to Parent. Parent shall be entitled to be reimbursed out of the Indemnity Fund for fifty percent (50%) of any amount that Parent is required to pay to the Indemnity Agent pursuant to such reimbursement obligation, payable in the manner set forth in Section 4 hereof.

The Indemnity Agent may resign at any time by giving thirty (30) days written notice to Parent and the Stockholders Representative; provided that such resignation shall not be effective unless and until a successor Indemnity Agent has been appointed and accepts such position pursuant to the terms of this Section 7. In such event, Parent and the Stockholders Representative shall appoint a successor Indemnity Agent or, if Parent and the Stockholders Representative are unable to agree upon a successor Indemnity Agent within thirty (30) days after

B-6

such notice, the Indemnity Agent shall be entitled to petition any court of competent jurisdiction for the appointment of a successor Indemnity Agent. Such appointment, whether by Parent and the Stockholders Representative, on the one hand, or such court, on the other hand, shall be effective on the effective date of the aforesaid resignation (the “Indemnity Transfer Date”). The Indemnity Agent’s sole responsibility after such thirty (30) day notice period expires shall be to hold the Indemnity Fund (without any obligation to reinvest the same) and to deliver the same to a designated successor indemnity agent, if any, or in accordance with the directions of a final order or judgment of a court of competent jurisdiction, at which time of delivery Indemnity Agent’s obligations hereunder shall cease and terminate. On the Indemnity Transfer Date, all right title and interest to the Indemnity Fund, including interest thereon, shall be transferred to the successor Indemnity Agent and this Indemnity Agreement shall be assigned by the Indemnity Agent to such successor Indemnity Agent, and thereafter, the resigning Indemnity Agent shall be released from any further obligations hereunder.

The Indemnity Agent shall not have any right, claim or interest in any portion of the Indemnity Fund except in its capacity as Indemnity Agent hereunder.

It is understood and agreed that in the event any disagreement among Parent and the Stockholders Representative results in adverse claims or demands being made in connection with the Indemnity Fund, or in the event the Indemnity Agent in good faith is in doubt as to what action it should take hereunder, the Indemnity Agent shall retain the Indemnity Fund until the Indemnity Agent shall have received (i) an enforceable final order of a court of competent jurisdiction which is not subject to further appeal directing delivery of the Indemnity Fund or (ii) a written agreement executed by Parent and the Stockholders Representative directing delivery of the Indemnity Fund, in which event Indemnity Agent shall disburse the Indemnity Fund in accordance with such order or agreement. Any court order referred to in clause (i) immediately above shall be accompanied by a legal opinion of counsel for the presenting party satisfactory to the Indemnity Agent to the effect that said court order or judgment is final and enforceable and is not subject to further appeal. The Parties agree to pursue any redress or recourse in connection with any dispute without making the Indemnity Agent a party to the same. The Indemnity Agent shall act on such court order and legal opinion without further question.

In no event shall the Indemnity Agent be liable in connection with this Indemnity Agreement for any special, indirect or consequential loss or damage of any kind whatsoever, even if the Indemnity Agent has been previously advised of such loss or damage.

In the event that any escrow property shall be attached, garnished or levied upon by any court order, or the delivery thereof shall be stayed or enjoined by an order of a court, or any order, judgment or decree shall be made or entered by any court order affecting the property deposited under this Indemnity Agreement, the Indemnity Agent is hereby expressly authorized, in its sole discretion, to obey and

B-7

comply with all writs, orders or decrees so entered or issued, which it is advised by legal counsel of its own choosing is binding upon it, whether with or without jurisdiction, and in the event that the Indemnity Agent obeys or complies with any such writ, order or decree it shall not be liable to any of the Parties hereto or to any other person, entity, firm or corporation, by reason of such compliance notwithstanding such writ, order or decree be subsequently reversed, modified, annulled, set aside or vacated.

Section 8. Stockholders Representative.

Pursuant to the Merger Agreement, the Stockholders Representative shall act as agent and attorney-in-fact for and on behalf of each of the Company Stockholders and the Company Vested Stock Optionholders receiving consideration pursuant to Article I of the Merger Agreement. The Stockholders Representative shall have full power and authority to represent all of such Company Stockholders and Company Vested Stock Optionholders and their respective successors with respect to all matters arising under this Indemnity Agreement and the Merger Agreement and all actions taken by the Stockholders Representative hereunder and thereunder shall be binding upon all such Company Stockholders and Company Vested Stock Optionholders and such successors as if expressly confirmed and ratified in writing by each of them. The Stockholders Representative shall take any and all actions which it believes are necessary or appropriate under this Indemnity Agreement and the Merger Agreement for and on behalf of such Company Stockholders and Company Vested Stock Optionholders, as fully as if such Company Stockholders and Company Vested Stock Optionholders were acting on their own behalf, including, without limitation, defending all indemnity claims pursuant to Section 8.2 of the Merger Agreement, consenting to, compromising or settling all such indemnity claims, conducting negotiations with Parent and the Indemnity Agent under this Indemnity Agreement and the Merger Agreement, taking any and all other actions specified in or contemplated by this Indemnity Agreement and the Merger Agreement, and engaging counsel, accountants or other Stockholders Representatives in connection with the foregoing matters. Without limiting the generality of the foregoing, the Stockholders Representative shall have full power and authority to interpret all the terms and provisions of this Indemnity Agreement and the Merger Agreement and to consent to any amendment hereof or thereof on behalf of all such Company Stockholders and Company Vested Stock Optionholders and such successors. The person designated to be Stockholders Representative may be changed in accordance with the provisions set forth in the Merger Agreement.

From time to time between the date hereof and six (6) days prior to the Distribution Date, the Stockholders Representative may deliver notice to the Indemnity Agent and Parent setting forth in reasonable detail the amount of the reasonable out-of-pocket expenses incurred by the Stockholders Representative in connection with its duties under the Merger Agreement and hereunder, in each case to the extent such expenses shall not have been reimbursed out of the

B-8

Indemnity Fund. Promptly following the Indemnity Agent’s receipt of such notice, it shall transfer to the Stockholders Representative from amounts available in the Indemnity Fund the amount set forth in such notice; provided, that the Indemnity Agent may not transfer more than $250,000 in the aggregate pursuant to this Section 8(b).

At least five (5) days prior to the Distribution Date, the Stockholders Representative shall deliver notice to the Indemnity Agent and Parent setting forth the amount of the reasonable out-of-pocket expenses incurred by the Stockholders Representative in connection with its duties under the Merger Agreement and hereunder, but only to the extent such expenses shall not have been reimbursed out of the Indemnity Fund. Such expenses shall be reimbursed from the Indemnity Fund in accordance with the provision of Section 5(b) hereof.

Neither Parent, any Parent Group Member nor the Indemnity Agent shall be responsible or liable for any acts or omissions of the Stockholders Representative in such Stockholders Representative’s capacity as such.

A decision, act, consent or instruction of the Stockholders Representative shall constitute a decision of all Company Stockholders and Company Vested Stock Optionholders and shall be final, binding and conclusive upon each such Company Stockholder and Company Vested Stock Optionholder, and the Indemnity Agent and Parent may rely upon any decision, act, consent or instruction of the Stockholders Representative as being the decision, act, consent or instruction of each and every such Company Stockholder and Company Vested Stock Optionholder. The Indemnity Agent and each Parent Group Member are hereby relieved from any liability to any person for any acts done by them in accordance with such decision, act, consent or instruction of the Stockholders Representative.

Section 9. Taxes.

All dividends, distributions, interest and gains earned or realized on the Indemnity Fund (“Earnings”) shall be treated as having been received by the Company Stockholders and the Company Vested Stock Optionholders and reported, as and to the extent required by law, by the Indemnity Agent to the Internal Revenue Service (“IRS”), or any other taxing authority, on IRS Form 1099 or 1042S (or other appropriate form) as income earned from the Indemnity Fund by the Company Stockholders and Company Vested Stock Optionholders whether or not said income has been distributed during such year. Annex A hereto sets forth a list of each Company Stockholder’s and Company Vested Stock Optionholder’s address, Taxpayer Identification Number, and pro rata share of the Indemnity Fund and the Indemnity Agent is authorized to rely upon this information for the purposes of performing its tax reporting as set forth herein. The Stockholders Representative shall cause the Company Stockholders and Company Vested Stock Optionholders to provide to the Indemnity Agent all forms and information necessary to complete such information returns and payee statements. In the event the Indemnity Agent becomes liable for the payment of taxes, including withholding taxes, relating to Earnings or any payment made hereunder, the Indemnity Agent may deduct such taxes from the Indemnity Fund. The Indemnity Agent shall withhold any taxes it deems appropriate, including but not limited to

B-9

required withholding in the absence of proper tax documentation, and shall remit such taxes to the appropriate authorities.

Section 10. Representations and Warranties.

Each of Parent and the Indemnity Agent represents and warrants to the other and to the Stockholders Representative that it is duly organized, validly existing and in good standing under the laws of its jurisdiction of formation; that it has the power and authority to execute and deliver this Indemnity Agreement and to perform its obligations hereunder; that the execution, delivery and performance of this Indemnity Agreement by it has been duly authorized and approved by all necessary action; that this Indemnity Agreement constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms; and that the execution, delivery and performance of this Indemnity Agreement by it will not result in a breach of or loss of rights under or constitute a default under or a violation of any trust (constructive or other), agreement, judgment, decree, order or other instrument to which it is a party or it or its properties or assets may be bound.

The Stockholders Representative represents to the Indemnity Agent and Parent that it has the power and authority to execute and deliver this Indemnity Agreement and to perform its obligations hereunder; that this Indemnity Agreement constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms; and that the execution, delivery and performance of this Indemnity Agreement by it will not result in a breach of or loss of rights under or constitute a default under or a violation of any trust (constructive or other), agreement, judgment, decree, order or other instrument to which it is a party or its properties or assets may be bound.

The Parties have provided the Indemnity Agent with their respective fully executed IRS Form W-8, or W-9 and/or other required documentation. The Parties each represent that its correct TIN assigned by the IRS, or any other taxing authority, is set forth in the delivered forms.

Section 11. Benefit; Successor and Assigns.

This Indemnity Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective successors and permitted assigns but shall not be assignable by any Party hereto without the written consent of the other Party and the Indemnity Agent; provided, however, that Parent may assign its rights and delegate its obligations hereunder to any successor corporation in the event of a merger, consolidation or transfer or sale of all or substantially all of Parent’s stock or assets and that the Indemnity Agent may assign its rights hereunder to a successor Indemnity Agent appointed hereunder. Except for the persons specified in the preceding sentence, this Indemnity Agreement is not intended to confer on any person not a party hereto any rights or remedies hereunder, including but not limited to the Company Stockholders, the Company Vested Stock Optionholders or any Parent Group Member.

B-10

Following the Effective Time, this Indemnity Agreement may only be terminated following the delivery of all amounts held in the Indemnity Fund and the delivery of notice by the Indemnity Agent as contemplated by Section 5(c) hereof.

Notwithstanding the above, in the case of communications delivered to the Indemnity Agent, such communications shall be deemed to have been received on the date received by an officer of the Indemnity Agent or any employee of the Indemnity Agent who reports directly to any such officer at the above-referenced office.

Section 14. Governing Law.

This Indemnity Agreement shall be governed by and construed in accordance with the laws (as opposed to conflicts of law provisions) of the State of Illinois.

Section 15. Counterparts.

This Indemnity Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

Section 16. Interpretation.

When a reference is made in this Indemnity Agreement to a Section or Annex, such reference shall be to a Section of, or Annex attached to, this Indemnity Agreement unless otherwise indicated. The Annexes referred to herein shall be construed with and as an integral part of this Indemnity Agreement to the same extent as if they were set forth verbatim herein. The section headings contained in this Indemnity Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Indemnity Agreement. For

B-12

purposes of this Indemnity Agreement, (i) the words “include,” “includes” or “including” shall be deemed to be followed by the words “without limitation”, and (ii) the words “herein,” “hereof,” “hereby,”, “hereto” and “hereunder” refer to this Indemnity Agreement as a whole. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neutral genders of such term.

Section 17. Partial Invalidity.

Notwithstanding anything else to the contrary in this Indemnity Agreement, it is the intent and understanding of each party hereto that if, in any action before any court or tribunal legally empowered to enforce this Indemnity Agreement, any term, restriction, covenant or promise in this Indemnity Agreement is found to be unreasonable and for that reason unenforceable, then such term, restriction, covenant or promise shall be deemed modified to the extent necessary to make it enforceable by such court or agency.

Section 18. Entire Agreement; Modification and Waiver.

This Indemnity Agreement and the Merger Agreement embody the entire agreement and understanding among the Indemnity Agent and the Parties with respect to the subject matter hereof and supersede any and all prior agreements and understandings relating to the subject matter hereof. Notwithstanding the preceding sentence, the parties hereto acknowledge that the Indemnity Agent is not a party to nor is it bound by the Merger Agreement. No amendment, modification or waiver of this Indemnity Agreement shall be binding or effective for any purpose unless it is made in a writing signed by the Party against whom enforcement of such amendment, modification or waiver is sought and acknowledged and accepted by the Indemnity Agent. No course of dealing between the parties to this Indemnity Agreement shall be deemed to affect or to modify, amend or discharge any provision or term of this Indemnity Agreement. No delay by any party to or any beneficiary of this Indemnity Agreement in the exercise of any of its rights or remedies shall operate as a waiver thereof, and no single or partial exercise by any party to or any beneficiary of this Indemnity Agreement of any such right or remedy shall preclude any other or further exercise thereof. No party to this Indemnity Agreement is liable to any other party for losses due to, or if it is unable to perform its obligations under the terms of this Indemnity Agreement because of, acts of God, fire, war, terrorism, floods, strikes, electrical outages, equipment or transmission failure, or other causes reasonably beyond its control. A waiver of any right or remedy on any one occasion shall not be construed as a bar to or waiver of any such right or remedy on any other occasion.

Section 19. Security Procedures.

a. In the event funds transfer instructions are given, whether in writing, by facsimile or otherwise, the Indemnity Agent is authorized to seek confirmation of such instructions by telephone call-back to the person or persons designated on Annex B, and the Indemnity Agent may rely upon the confirmation of anyone purporting to be the person or persons so designated. The persons and telephone numbers for call-backs may be changed only in a writing actually received and acknowledged by the Indemnity Agent. If the Indemnity Agent is unable to contact

B-13

any of the authorized representatives identified in Annex B, no funds shall be wired until such confirmation can be accomplished as set forth in this Section 19(a). The Indemnity Agent and the beneficiary’s bank in any funds transfer may rely solely upon any account numbers or similar identifying numbers provided by Parent or Stockholders Representative to identify (a) the beneficiary, (b) the beneficiary’s bank, or (c) an intermediary bank. The Indemnity Agent may apply any of the Indemnity Funds for any payment order it executes using any such identifying number, even when its use may result in a person other than the beneficiary being paid, or the transfer of funds to a bank other than the beneficiary’s bank or an intermediary bank designated. The Parties acknowledge that these security procedures are commercially reasonable.

b. Parent acknowledges that repetitive funds transfer instructions may be given to the Indemnity Agent for one or more beneficiaries where only the date of the requested transfer, the amount of funds to be transferred, and/or the description of the payment shall change within the repetitive instructions (“Standing Settlement Instructions”). Accordingly, Parent shall deliver to the Indemnity Agent such specific Standing Settlement Instructions only for each respective beneficiary as set forth in Annex B to this Indemnity Agreement, by facsimile or other written instruction. The Indemnity Agent may rely solely upon such Standing Settlement Instructions and all identifying information set forth therein for each beneficiary. The Indemnity Agent and Parent agree that such Standing Settlement Instructions shall be effective as the funds transfer instructions of Parent, without requiring a verifying callback, whether or not authorized, if such Standing Settlement Instructions are consistent with previously authenticated Standing Settlement Instructions for that beneficiary. Parent acknowledges that such Standing Settlement Instructions are a security procedure and are commercially reasonable.

Section 20. Patriot Act Disclosure.

Section 326 of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA PATRIOT Act”) requires the Indemnity Agent to implement reasonable procedures to verify the identity of any person that opens a new account with it. Accordingly, the Parties acknowledge that Section 326 of the USA PATRIOT Act and the Indemnity Agent’s identity verification procedures require the Indemnity Agent to obtain information which may be used to confirm the Parties identity including without limitation name, address and organizational documents (“identifying information”). The Parties agree to provide the Indemnity Agent with and consent to the Indemnity Agent obtaining from third parties any such identifying information required as a condition of opening an account with or using any service provided by the Indemnity Agent.

Tellabs, Inc.

▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇

▇▇▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇

Re: WiChorus, Inc.

Ladies and Gentlemen:

Reference is made to the Agreement and Plan of Merger, dated as of October 20, 2009 (the “Agreement”), by and among Tellabs, Inc., a Delaware corporation (“Parent”), Tellabs Willow Corp., a Delaware corporation and a direct wholly owned subsidiary of Parent (“Sub”) and WiChorus, Inc., a Delaware corporation (the “Company”), providing for, among other things, the merger of Sub with and into the Company, with the Company surviving the merger and becoming a direct wholly owned subsidiary of the Company (the “Merger”). This opinion letter is delivered to Parent pursuant to Section 1.15(d)(v) of the Agreement, and all capitalized terms used herein have the meanings defined for them in the Agreement unless otherwise defined herein. Reference in this opinion letter to the Agreement excludes any schedule (other than the Disclosure Schedule) or substantive agreement attached as an exhibit to the Agreement, unless otherwise indicated herein. As used herein, “Transaction Documents” means the Agreement and the Certificate of Merger.

We have acted as counsel for the Company in connection with the negotiation, preparation and execution of the Agreement. As such counsel, we have made such legal and factual examinations and inquiries as we have deemed advisable or necessary for the purpose of rendering the opinions set forth herein. In addition, we have received and reviewed originals or copies of such agreements, instruments, corporate records of the Company, certificates of public officials, one or more certificates of the Company as to factual matters and such other documents that we consider necessary or advisable for the purpose of rendering the opinions set forth herein. We have not independently established the facts stated in any of the foregoing. In such examination, we have assumed the genuineness of all signatures, the authenticity and completeness of all documents submitted to us as originals and the conformity to original documents of all copies submitted to us. In making our examination of documents, we have assumed that each party to any such document (other than the Company) has satisfied those requirements that are applicable to it to the extent necessary to make such document a valid and binding obligation of such party, enforceable against such party in accordance with its terms.

As used in the opinions or statements set forth below, the expressions “to our knowledge,” “known to us” or similar language with reference to matters of fact refer to the

D-1

current actual knowledge of the attorneys of this firm who have rendered legal services in connection with the representation described in the second paragraph of this opinion letter. Except to the extent expressly set forth herein, we have not undertaken any independent investigation to determine the existence or absence of any fact, and no inference as to our knowledge of the existence or absence of any fact should be drawn from our representation of the Company or the rendering of the opinions set forth herein.

We have assumed that (i) the representations and warranties as to factual matters made by the parties to the Agreement and pursuant thereto are correct, (ii) corporate records of the Company are complete and accurate, (iii) certificates of public officials or the Company that we have received and reviewed in connection with rendering the opinions set forth herein are accurate; and (iv) the parties to the Agreement have complied and will comply with their obligations under the Agreement.

We are members of the Bar of the State of California and we express no opinion as to any matter relating to the laws of any jurisdiction other than the federal laws of the United States of America, the General Corporation Law of the State of Delaware and the laws of the State of California. We note that the parties to the Agreement have designated the laws of the Delaware as the laws governing the Agreement. The opinion in paragraph 3 below as to the validity, binding effect and enforceability of the Agreement is based solely upon the result that would be obtained if a California court were to apply the internal laws of the State of California (excluding conflicts of law principles) to the interpretation and enforcement of the Agreement.

In rendering the opinions set forth in paragraph 1 below, we have relied solely upon a copy of the certificate of incorporation of the Company certified by the Secretary of State of the State of Delaware and certificates from the Secretary of State and Franchise Tax Board of the State of California.

In rendering the opinions set forth in paragraph 5 below, we have relied solely upon a review of the certificate of incorporation and bylaws of the Company, minute books relating to meetings and written actions of the board of directors and stockholders of the Company, stock records of the Company, the relevant financing transaction documents and statements in a certificate executed by an officer of the Company relating to the capitalization of the Company, including a statement to the effect that the Company has received consideration in the amount and in the form specified by the board of directors for all of the issued and outstanding shares of capital stock of the Company.

The opinions hereinafter expressed are subject to the following additional qualifications and assumptions:

(a) We express no opinion as to the effect of applicable bankruptcy, insolvency, reorganization, moratorium or other similar federal or state laws affecting the rights of creditors;

(b) We express no opinion as to the effect of general principles of equity, including without limitation concepts of materiality, reasonableness, good faith and fair dealing, and the possible unavailability of specific performance or injunctive relief, regardless of

D-2

whether considered in a proceeding in equity or at law;

(c) We express no opinion as to the enforceability of any provision of the Agreement (i) purporting to waive broadly or vaguely stated rights, unknown future defenses, rights to damages, rights to jury trials, any statute of limitations for a period in excess of four years beyond the statutory period or the benefits of other statutory, regulatory or constitutional rights that cannot be waived or, if they can be waived, cannot be waived prospectively; (ii) providing for a choice of venue; (iii) imposing penalties, forfeitures or liquidated damages; or (iv) prescribing or varying rules of evidence, method or quantum of proof or other legal standards in a manner contrary to applicable statutes and rules of law;

(d) We express no opinion as to the enforceability of the choice of law provisions of the Transaction Documents;

(e) We express no opinion as to the enforceability of the Support and Release Agreement or any other provisions in the Transaction Documents concerning the voting of the Company’s capital stock;

(f) We express no opinion as to the effect of California Business & Professions Code 16600 et seq. as to the enforceability of any non-competition provision in the Transaction Documents; and

(g) We express no opinion as to the enforceability of indemnification and contribution provisions to the extent they may be subject to limitations of public policy and the effect of applicable statutes and rules of law.

Based upon and subject to the foregoing, and except as set forth in the Disclosure Schedule, we are of the opinion that:

1. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware. The Company is duly qualified to do business as a foreign corporation and is in good standing in the State of California.

2. The Company has the requisite corporate power to carry on its business as currently being conducted, and to execute and deliver each of the Transaction Documents, to perform its obligations thereunder and to consummate the transactions contemplated by the Agreement (including the Merger).

3. The execution and delivery of each of the Transaction Documents, the performance by the Company of its obligations under the Transaction Documents, and the consummation by the Company of the transactions contemplated by the Transaction Documents (including the Merger), have been duly authorized by all necessary corporate action on the part of the Company and its stockholders and no further action is required on the part of the Company or its stockholders to authorize any Transaction Document or the transactions contemplated by the Transaction Documents (including the Merger). The Agreement has been duly executed and delivered by the Company, and assuming due authorization, execution and delivery by each other party thereto, constitutes a valid and binding obligation of the Company, enforceable against the Company in accordance with its terms.

D-3

4. The execution and delivery by the Company of the Transaction Documents, the performance by the Company of its obligations thereunder and the consummation by the Company of the transactions contemplated by the Transaction Documents (including the Merger), do not and will not conflict with or result in any violation of or default under any provision of the Company’s Amended and Restated Certificate of Incorporation or Bylaws, and, do not and will not violate, conflict with, result in any breach of or constitute a default under any judgment, decree or order that is known by us to be applicable to the Company.

5. Immediately prior to the Effective Time, the authorized capital stock of the Company consisted of (i) [ ] shares of Company Common Stock, of which on the date hereof [ ] shares are issued and outstanding and (ii) [ ] shares of Company Preferred Stock, of which on the date hereof (A) [ ] shares have been designated Series A Preferred Stock, of which on the date hereof [ ] shares are issued and outstanding, (B) [ ] shares have been designated Series B Preferred Stock, of which on the date hereof [ ] shares are issued and outstanding, (C) [ ] shares have been designated Series B-1 Preferred Stock, of which on the date hereof [ ] shares are issued and outstanding, (D) [ ] shares have been designated Series C Preferred Stock, of which on the date hereof [ ] shares are issued and outstanding. [ ] shares have been reserved for issuance pursuant to the Company’s 2005 Stock Plan. All of the issued and outstanding shares of capital stock of the Company have been duly authorized and validly issued and are fully paid and non-assessable.
