Exhibit 10.17

CONSENT AND AMENDMENT NO. 3 TO LOAN AND SECURITY AGREEMENT

     This CONSENT AND AMENDMENT NO. 3 TO LOAN AND SECURITY AGREEMENT (“Amendment”) is dated as of October 15, 2009, and is entered into by and among BroadSoft, Inc., a Delaware corporation (“Parent”), BroadSoft International, Inc” a Delaware corporation (“International”), BroadSoft M6, LLC, a Delaware limited liability company (“M6”), BroadSoft Sylantro, Inc., a Delaware corporation (“Sylantro”; and together with Parent, International and M6, the “Existing Borrowers”, and each an “Existing Borrower”), BroadSoft PacketSmart, Inc., a Delaware corporation (“PacketSmart”; and together with Parent, International, M6, and Sylantro, the “Borrowers”, and each a “Borrower”), and ORIX Venture Finance, LLC, a Delaware limited liability company (“Lender”). As described below, it is anticipated that PacketSmart will merge with PacketIsland, Inc., a Delaware corporation (“Packet Island”), with Packet Island surviving the merger and, effective upon the consummation of such merger, changing its name to BroadSoft PacketSmart, Inc, (which will continue to be a Delaware corporation), and which entity is being added as a new Borrower pursuant to the terms hereof, all on the date hereof as described below.

WITNESSETH:

          WHEREAS, Existing Borrowers and Lender are parties to that certain Loan and Security Agreement dated as of September 26, 2008 (as amended from time to time being referred to herein as the “Loan Agreement”; capitalized terms not otherwise defined herein have the definitions provided therefore in the Loan Agreement);

          WHEREAS, Existing Borrowers have informed Lender that, for purposes of effectuating the “Merger” (as defined below), Parent formed a new wholly-owned Subsidiary, PacketSmart, and that PacketSmart has had no operations to date;

          WHEREAS, Existing Borrowers have informed Lender that Parent desires to effect a merger of PacketSmart with and into Packet Island, pursuant to the terms of that certain Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) among Parent, PacketSmart, Packet Island and certain other parties as identified therein, a copy of which is attached hereto as Exhibit A (the “Merger”), with Packet Island being the surviving entity of such merger and, immediately after giving effect thereto, changing its name to BroadSoft PacketSmart, Inc. (the “New Borrower”);

          WHEREAS, in the absence of the prior written consent of Lender, the Merger would constitute a Default under Sections 4.5(i) and 4.5(ii) of the Loan Agreement and a corresponding Event of Default under Section 6.1 (d) of the Loan Agreement; and

          WHEREAS, Existing Borrowers have requested that Lender (a) consent to the Merger, (b) amend the Loan Agreement to add PacketSmart as a “Borrower” under the Loan Agreement and (c) amend the Loan Agreement in certain other respects as set forth herein.

          NOW THEREFORE, in consideration of the mutual conditions and agreements set forth in the Loan Agreement and this Amendment, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

          1. Joinder. Subject to the satisfaction of the conditions set forth in Section 6 below, and in reliance on the representations set forth in Section 7 below, the parties hereto agree that PacketSmart is hereby joined to the Loan Agreement and the other Loan Documents as a “Borrower” and PacketSmart hereby agrees to be bound by all of the terms and conditions (including without limitation all of the representations and warranties and covenants) of the Loan Agreement and the other Loan Documents, as a “Borrower”, in each case as if PacketSmart were a direct signatory thereto. In furtherance of the preceding sentence, without limiting any provision of the Loan Agreement or any other Loan Document to which PacketSmart is now becoming a party as a “Borrower”, and in accordance with the terms of the Loan Agreement and the other Loan Documents, PacketSmart (i) agrees to be jointly and severally liable with each other Borrower for the Loans and other Obligations; (ii) grants a lien in all Collateral to secure all of the Loans and other Obligations; and (iii) acknowledges and agrees that it has become a guarantor under and pursuant to the provisions of Section 9 of the Loan Agreement and has agreed to the terms and conditions regarding the “Suretyship Waivers” set forth in Exhibit C to the Loan Agreement.

          While the Loan described in Section 1 of the Schedule to the Loan Agreement was made on or around September 26, 2008 to certain of the Existing Borrowers (and not to PacketSmart), to limit the number of changes to the Loan Agreement and other Loan Documents necessary to subject PacketSmart to all of the terms and conditions thereof (including those described in the first paragraph of this Section 1) the term “Borrower” is used to include PacketSmart even though such Loan was not made to PacketSmart. PacketSmart unconditionally guaranties, and is jointly and severally liable for, such Loan and all of the other Obligations.

          2. Consent. Subject to the satisfaction of the conditions set forth in Section 6 below, and in reliance on the representations set forth in Section 7 below, Lender hereby consents to the consummation of the Merger pursuant to the terms of the Merger Agreement. The foregoing is a limited consent and shall not constitute a consent to or waiver of any other Defaults or Events of Default that are now in existence or that may hereafter occur.

          3. Amendments. Subject to the satisfaction of the conditions set forth in Section 6 below, and in reliance on the representations set forth in Section 7 below. the Loan Agreement is amended as follows:

          (a) The defined term “Representations” set forth in Section 7 to the Loan Agreement is hereby amended and restated ill its entirety as follows:

     “Representations” means the (i) written Representations and Warranties previously delivered by Parent to ORIX dated September 23, 2008; (ii) the written Representations and Warranties delivered by Sylantro to ORIX dated December 15, 2008; and (iii) the written Representations and Warranties regarding Packet Island, Inc, delivered by Packet Island to ORIX dated October 8, 2009.

          4. Collateral Assignment of Undertakings under Merger Agreement. To induce Lender to enter into this Amendment, Borrowers hereby agree that:

          (a) each of Parent and PacketSmart hereby collaterally assigns and grants to Lender, as additional security for the payment and performance in full of the Obligations, a security interest in all of its rights and remedies with respect to any and all of the representations, warranties, covenants, indemnification agreements and other agreements made, and certain rights granted, in its favor pursuant to the Merger Agreement (collectively, the “Undertakings”);

          (b) each of Parent and PacketSmart agrees to (i) promptly notify Lender of each and every material dispute with, and material claim against, any person or entity for which it has a claim under the Merger Agreement; (ii) diligently enforce each such claim (unless Parent and PacketSmart determine reasonably and in good faith that it would not be commercially reasonable to enforce any such claim); and (iii) promptly provide Lender with copies of all material notices, demands, requests and other material communications sent or received by it pursuant to the Merger Agreement as well as prior written notice of its intention to exercise any power, right or remedy pursuant to the Merger Agreement;

          (c) in no event shall either Parent or PacketSmart, without the prior written consent of Lender (such consent not to be unreasonably withheld, delayed or conditioned), waive, release or discharge any person or entity with respect to any Undertaking or compromise or settle any claim or dispute with respect to any such Undertaking, and no such waiver, release, discharge, compromise or settlement shall be effective without the prior written consent of Lender;

          (d) each of Parent and PacketSmart hereby irrevocably authorizes and empowers Lender as its agent at any time after the occurrence and during the continuance of an Event of Default to (i) either directly or its behalf, assert any claims and demands and enforce any rights and remedies as it may have, from time to time, with respect to the Undertakings, as Lender may deem proper, and (ii) receive and collect any and all proceeds, awards or amounts due under the Merger Agreement and apply all such amounts on account of the Obligations in the manner described in Loan Agreement;

          (e) each of Parent and PacketSmart hereby irrevocably makes, constitutes and appoints Lender (and all officers, employees or agents designated by Lender) as its true and lawful attorney (and agent-in-fact) for the purpose of enabling Lender or its agent to assert, at any time after the occurrence and during the continuance of an Event of Default, any claims and demands or enforce any rights and remedies and receive and collect such proceeds, awards and amounts and to apply such monies to the Obligations in the manner described in Loan Agreement; and

          (f) Lender shall not be deemed to have assumed any of the obligations or liabilities of either Parent or PacketSmart under the Merger Agreement by reason of this Section 4 or otherwise, and Borrowers further agree to indemnify, protect, defend and hold Lender harmless from and with respect to any claims or demands thereunder other than to the extent arising from the gross negligence or willful misconduct by Lender as determined by a court of competent jurisdiction.

The payment of the Carve-Out Payment to the Carve-Out Recipients represents payment in full of all obligations of the Company and Parent under the Carve-Out Plan at and after the Effective Time.

     1.7 Treatment of Stock Options and Warrants.

          (a) Parent is not assuming or continuing the Company Equity Plan or any equity plans applicable to the employees or other service providers of the Company or its affiliates. Parent is not continuing, assuming or substituting for any Company Options or other convertible securities granted under the Company Equity Plan. At or immediately prior to the Effective Time, and in accordance with the terms of the Company Equity Plan and resolutions adopted by the Company’s board of directors prior to the date hereof, the vesting and exercisability of all outstanding Company Options granted under the Company Equity Plan shall be accelerated in full, and any such Company Options that are not exercised in accordance with procedures established by the Company prior to the Effective Time shall be terminated and cancelled without the payment of any additional consideration to the holders of such Company Options.

          (b) At or prior to the Effective Time, the board of directors of the Company shall adopt any resolutions, in form and substance reasonably satisfactory to Parent, and take any actions which are necessary, to effectuate the provisions of this Section 1.7, including the adoption of resolutions terminating the Company Equity Plan and terminating and cancelling any outstanding Company Options granted thereunder without additional consideration as of the Effective Time.

          (c) Parent is not continuing, assuming or substituting for any Company Warrants.

The board of directors of the Company shall adopt any resolutions, in form and substance reasonably satisfactory to Parent, and take any actions which are necessary, including the providing of any requisite notice to each holder of a Company Warrant prior to the Effective Time, to effectuate the provisions of this Section 1.7(c).

     1.8 Closing of the Company’s Transfer Books. At the Effective Time, holders of certificates representing shares of the Company’s capital stock that were outstanding immediately prior to the Effective Time (“Company Capital Stock”) shall cease to have any rights as stockholders of the Company, and the stock transfer books of the Company shall be closed with respect to all shares of such capital stock outstanding immediately prior to the Effective Time. No further transfer of any such shares of Company Capital Stock shall be made on such stock transfer books after the Effective Time. If, after the Effective Time, a valid certificate previously representing any of such shares of Company Capital Stock (a “Company Stock Certificate”) is presented to the Surviving Corporation or Parent, such Company Stock Certificate shall be canceled.

     1.9 Exchange of Notes; Full Satisfaction of Obligations.

          (a) At or as soon as practicable after the Effective Time, Parent will send to the holders of Company Notes instructions for use in effecting the surrender of Company Notes in exchange for certificates representing Parent Series E-1 Preferred. Upon surrender of a Company Note to Parent for exchange, with such other documents as may be reasonably required by Parent, the holder of such Company Note shall be entitled to receive in exchange therefor a certificate representing the number of whole shares of Parent Series E-1 Preferred that such holder has the right to receive pursuant to the provisions of this Section 1. Until surrendered as contemplated by this Section 1.9, each Company Note shall be deemed, from and after the Effective Time, to represent only the right to receive upon such surrender a certificate representing shares of Parent Series E-1 Preferred (and cash in lieu of any fractional share of Parent Series E-1 Preferred) as contemplated by this Section 1. If any Company Note shall have been lost, stolen or destroyed, Parent may, in its discretion and as a condition precedent to the issuance of any certificate representing shares of Parent Series E-1 Preferred, require the owner of such lost, stolen or destroyed Company Note to provide an appropriate affidavit and to deliver a bond (in such sum as Parent may reasonably direct) as indemnity against any claim that may be made against Parent or the Surviving Corporation with respect to such Company Note.

          (b) No dividends or other distributions declared or made with respect to Parent Series E-1 Preferred with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Note with respect to the shares of Parent Series E-1 Preferred represented thereby, and no cash payment in lieu of any fractional share shall be paid to any such holder, until such holder surrenders such Company Note in accordance with this Section 1.9 (at which time such holder shall be entitled to receive all such dividends and distributions and such cash payment).

          (c) No fractional shares of Parent Series E-1 Preferred shall be issued in connection with the Merger, and no certificates for any such fractional shares shall be issued. In lieu of such fractional shares, any holder of a Company Note who would otherwise be entitled to receive a fraction of a share of Parent Series E-1 Preferred (after aggregating all fractional shares of Parent Series E-1 Preferred issuable to such holder) shall, upon surrender of such holder’s Company Note(s), be paid in cash the dollar amount (rounded to the nearest whole cent), without interest, determined by multiplying such fraction by $1.00.

          (d) Parent and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable to any holder or former holder of Company Notes pursuant to this Agreement such amounts as Parent or the Surviving Corporation may be required to deduct or withhold therefrom under the Code or under any provision of state, local or foreign tax law. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the Person to whom such amounts would otherwise have been paid.

          (e) Neither Parent nor the Surviving Corporation shall be liable to any holder or former holder of Company Notes for any shares of Parent Series E-1 Preferred (or dividends or distributions with respect thereto), or for any cash amounts, delivered to any public official pursuant to any applicable abandoned property, escheat or similar law.

          (f) The issuance of the shares of Parent Series E-1 Preferred upon cancellation and conversion of the Company Notes at the Effective Time shall constitute full satisfaction of the Company’s and Parent’s obligations under the Company Notes, and, at the Effective Time: (i) this Agreement shall be deemed to amend and terminate each of the Company Notes, each of which shall be cancelled and of no further force or effect as of the Effective Time; (ii) any and all obligations, liabilities, claims, expenses, liens, actions, rights and interests the holders of the Company Notes have or may have in the future arising under or related to the Company Notes or any agreement associated therewith, including, without the limitation, the Note Purchase Agreements, are waived to the fullest extent of the law and the Company and Parent (including any of their respective officers, directors, employees, affiliates and successors and assigns) are hereby released from the same to the fullest extent of the law; (iii) this Agreement shall be deemed to terminate all agreements relating to the Company Notes, including, without limitation, the Note Purchase Agreements, which agreements shall be of no further force or effect as of the Effective Time; and (iv) each of the holders of the Company Notes hereby agrees to promptly take any further action and to execute any and all additional documents or instruments requested by the Company or Parent to release the Company and Parent (including any of their respective officers, directors, employees, affiliates and successors and assigns) from their obligations under the Company Notes and any agreement associated

therewith, including, without limitation, the Note Purchase Agreements, and terminate any liens or security interests that may have arisen in connection with the Company Notes. Effective upon the Effective Time, each of the holders of Company Notes hereby authorizes the Company or Parent or their respective agents to file any and all appropriate UCC termination statements and any and all appropriate termination statements with the United States Patent and Trademark Office.

     1.10 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, any share of Company Capital Stock that is issued and outstanding immediately prior to the Effective Time and which is held by a stockholder who did not consent to or vote in favor of the approval of this Agreement, which stockholder complies with all of the provisions of Section 262 of the DGCL and, if applicable by virtue of Section 2115 of the CGCL, Chapter 13 of the CGCL, relevant to the exercise of dissenters’ rights (such share being a “Dissenting Share,” and such stockholder being a “Dissenting Stockholder”), shall not be entitled to receive any consideration pursuant to the terms set forth in Section 1.5, but shall be converted into the right to receive such consideration as may be determined to be due with respect to such Dissenting Share pursuant to Section 262 of the DGCL and, if applicable by virtue of Section 2115 of the CGCL, Chapter 13 of the CGCL. If any Dissenting Stockholder fails to perfect such stockholder’s dissenters’ rights under Section 262 of the DGCL and, if applicable by virtue of Section 2115 of the CGCL, Chapter 13 of the CGCL, or effectively withdraws or otherwise loses such rights with respect to any Dissenting Shares, such Dissenting Shares shall not be entitled to receive any consideration pursuant to the terms set forth in Section 1.5.

     1.11 Aggregate Merger Consideration Adjustment.

          (a) On the Closing Date, and subject to the terms and conditions contained herein (including, without limitation, Section 7.14), the Aggregate Merger Consideration shall be subject to adjustment in accordance with this Section 1.11. On the Closing Date, the Company will have (i) at least $800,000 in Cash and (ii) at least $788,000 in Net Assets, each as of immediately prior to the Effective Time, before giving effect to the Merger, but after payment of all fees, costs and expenses of the type contemplated by Sections 2.23 (and Part 2.23 of the Company Disclosure Schedule), 7.8(d), 7.8(e) and 11.3(b).

          (b) Not later than three calendar days prior to the Closing Date, the Company will prepare and deliver to Parent a balance sheet setting forth the Company’s good faith estimate of Cash and Net Assets, as of immediately prior to the Effective Time, before giving effect to the Merger, but after payment of all fees, costs and expenses of the type contemplated

by Sections 2.23 (and Part 2.23 of the Company Disclosure Schedule), 7.8(d), 7.8(e) and 11.3(b) (the “Estimated Balance Sheet”) and a statement setting forth a detailed calculation of the Estimated Balance Sheet Adjustment (as defined below) (collectively, the “Estimated Balance Sheet Adjustment Statement”). The Estimated Balance Sheet Adjustment Statement will be prepared in accordance with GAAP. As promptly as practicable, but not later than one calendar day prior to the Closing Date, Parent shall notify the Company of any adjustments that it reasonably believes are required to the Estimated Balance Sheet or the Estimated Balance Sheet Adjustment. Parent and the Company shall use their reasonable best efforts to promptly resolve any dispute regarding such adjustments prior to Closing, after which the Company will deliver a revised Estimated Balance Sheet Adjustment Statement reflecting any agreed upon adjustments to the Estimated Balance Sheet or Estimated Balance Sheet Adjustment. In the event that the Estimated Balance Sheet reflects Net Assets in excess of $788,000, then, subject to Section 1.11(d) and Section 1.11(e) below, the Aggregate Merger Consideration shall be increased, by the amount of such excess, by one share of Parent Series E-1 Preferred for every one dollar of the excess (including fractions thereof, but subject to Section 1.9(c)). “Estimated Balance Sheet Adjustment” means the amount of the total excess as contemplated in the immediately preceding sentence which results in an increase to the Aggregate Merger Consideration in accordance with this Section 1.11(b). Any additional shares of Parent Series E-1 Preferred to be issued with respect to the Estimated Balance Sheet Adjustment pursuant to this Section 1.11(b) shall be held in escrow by Parent pending the determination of the Final Balance Sheet Adjustment pursuant to Sections 1.11 (c) and (d) below.

          (c) Within sixty (60) days after the Closing Date, Parent shall prepare and deliver to the Agent a statement setting forth the actual Cash and Net Assets, as of immediately prior to the Effective Time, before giving effect to the Merger (the “Final Balance Sheet”) and a statement setting forth a detailed calculation of the Final Balance Sheet Adjustment (as defined below) (collectively, the “Closing Balance Sheet Adjustment Statement”). The Closing Balance Sheet Adjustment Statement will be prepared in accordance with GAAP. The Agent may, upon reasonable request, review the work papers used in Parent’s preparation of the Closing Balance Sheet Adjustment Statement, and Parent shall make available to the Agent all such work papers or other documents and information related thereto as may be reasonably requested by the Agent, subject to the Agent’s execution of any access or similar letters reasonably requested by service providers engaged by Parent in connection with Parent’s preparation of the Closing Balance Sheet Adjustment Statement. If within ten (10) days following delivery of the Closing Balance Sheet Adjustment Statement, the Agent has not given Parent notice of its objection to the Closing Balance Sheet Adjustment Statement (such notice must contain a statement of the basis of the Agent’s objection), then the Closing Balance Sheet Adjustment Statement will be used in computing the Final Balance Sheet Adjustment. If the Agent gives such notice of objection, with a statement of the basis of such objection, within such 10-day period, then Parent and the Agent shall meet promptly in an attempt to resolve such objection. If Parent and the Agent are unable to resolve the Agent’s objection in the 10-day period following Parent’s receipt of notice of the Agent’s objection, then the issues in dispute will be submitted to a nationally recognized independent public accounting firm that has not represented Parent or the Company (or any of their respective affiliates) in the past five years as shall be agreed upon by Parent and the Agent or if Parent and the Agent cannot agree, then Parent’s accountants and the Agent’s accountants shall select such independent public accounting firm (the “Firm”) for resolution. If issues in dispute are submitted to the Firm for

resolution, (i) each party will furnish to the Firm such work papers and other documents and information relating to the disputed issues as the Firm may reasonably request and are available to that party or its subsidiaries (or its independent public accountants), and will be afforded the opportunity to present to the Firm any material relating to the determination and to discuss the determination with the Firm; (ii) the determination by the Firm, as set forth in a notice delivered to Parent and the Agent by the Firm, will be binding and conclusive on the parties; and (iii) Parent and the Agent will each bear one-half of the fees of the Firm for such determination. In deciding any issues in dispute, the Firm shall be bound by the provisions of this Section 1.11 and may not assign a value to any item greater than the highest value for such item claimed by either Parent or the Agent or less than the lowest value for such item claimed by Parent or the Agent. The term “Final Balance Sheet Adjustment Statement” will mean the definitive Closing Balance Sheet Adjustment Statement agreed to by Parent and the Agent in accordance with this Section 1.11(c) or resulting from the determination made by the Firm in accordance with this Section 1.11(c).

          (d) In the event that the Final Balance Sheet reflects Net Assets less than the Net Assets reflected on the Estimated Balance Sheet, then, subject to Section 1.11(e) below, the Aggregate Merger Consideration (including any increase thereto as previously determined pursuant to Section 1.11(b) above) shall be decreased by the amount of such shortfall, by one share of Parent Series E-1 Preferred for every one dollar of the shortfall (including fractions thereof, but subject to Section 1.9(c)). In the event that the Final Balance Sheet reflects Net Assets in excess of the Net Assets reflected on the Estimated Balance Sheet, then, subject to Section 1.11(e) below, the Aggregate Merger Consideration (including any increase thereto as previously determined pursuant to Section 1.11(b) above) shall be increased by the amount of such excess, by one share of Parent Series E-1 Preferred for every one dollar of the excess (including fractions thereof, but subject to Section 1.9(c)). Any additional shares of Parent Series E-1 Preferred to be issued by Parent in accordance with this Section 1.11, shall be issued to the holders of Class B Notes and the Carve-Out Recipients on a pro rata basis in accordance with each such party’s pro rata portion of the Aggregate Merger Consideration as set forth on Exhibits A-1 and A-2 attached hereto (and with 15% of such additional shares to be deposited into escrow pursuant to Section 10.2 below). “Final Balance Sheet Adjustment” means the total amount of the excess or shortfall as contemplated above which results in an increase or decrease, as the case may be, to the Aggregate Merger Consideration (including any increase thereto as previously determined pursuant to Section 1.11(b) above) in accordance with this Section 1.11(d) and subject to Section 1.11 (e) below.

          (e) Notwithstanding the foregoing provisions of this Section 1.11, the aggregate amount of additional shares of Parent Series E-1 Preferred issued pursuant to this Section 1.11 with respect to the Estimated Balance Sheet Adjustment and the Final Balance Sheet Adjustment shall in no event exceed a total of 100,000 shares of Parent Series E-1 Preferred, and in no event shall any decrease in shares of Parent Series E-1 Preferred determined in accordance with Section 1.11(d) above, result in an Aggregate Merger Consideration less than 1,500,000 shares of Parent Series E-1 Preferred.

     1.12 Further Action. If, at any time after the Effective Time, any further action is determined by Parent to be necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation or Parent with full right, title and possession of and to all rights

and property of Merger Sub and the Company, the officers and directors of the Surviving Corporation and Parent shall be fully authorized (in the name of Merger Sub, in the name of the Company and otherwise) to take such action.

          (c) by the Company, if Parent or Merger Sub breaches or fails to perform in any material respect of any of its representations, warranties or covenants contained in this Agreement, which breach or failure to perform (i) would give rise to the failure of a condition set forth in Section 8.1 or 8.2, and (ii) (A) cannot be cured or (B) if curable through the exercise of commercially reasonable efforts, has not been cured within thirty (30) days after the giving of written notice to the Parent of such breach (provided that the Company, the Signing Noteholders and the Carve-Out Recipients are not then in willful breach of any representation, warranty or covenant in this Agreement);

          (d) by Parent if Parent reasonably determines that the timely satisfaction of any condition set forth in Section 7 has become impossible (other than as a result of any failure on the part of Parent or Merger Sub to comply with or perform any covenant or obligation of Parent or Merger Sub set forth in this Agreement);

          (e) by the Company if the Company reasonably determines that the timely satisfaction of any condition set forth in Section 8 has become impossible (other than as a result of any failure on the part of the Company or any of the Signing Noteholders or Carve-Out Recipients to comply with or perform any covenant or obligation set forth in this Agreement);

          (f) by Parent if the Closing has not taken place on or before October 15, 2009 (the “Outside Date”) (other than as a result of any failure on the part of Parent or Merger Sub to comply with or perform any covenant or obligation of Parent or Merger Sub set forth in this Agreement);

          (g) by the Company if the Closing has not taken place on or before the Outside Date (other than as a result of the failure on the part of the Company or any of the Signing Noteholders or Carve-Out Recipients to comply with or perform any covenant or obligation set forth in this Agreement); or

SECTION 10. Indemnification, Etc.

     10.1 Survival of Representations, Etc.

          (a) The representations and warranties of each party to this Agreement shall survive for twelve (12) months following the Closing and then terminate and expire, except that (i) the Specified Representations shall survive the Closing indefinitely; (ii) the Tax Representations shall survive the Closing and then terminate and expire upon the expiration of the applicable statute of limitations; and (iii) the IP Representations shall survive the Closing and then terminate and expire upon the three (3)-year anniversary of the Closing Date; provided, however, that if a Claim Notice (as defined below) with respect to a particular representation, warranty or covenant of any party is given to such party on or prior to the applicable expiration date of such representation, warranty or covenant, then, notwithstanding anything to the contrary contained in this Section 10.1(a), the claim asserted in such Claim Notice shall survive until such time as such claim is fully and finally resolved. The covenants of each party to this Agreement shall survive the Closing indefinitely unless a shorter period is specified herein. No claim for a breach of a representation, warranty, covenant or indemnification obligation may be made or brought by any party hereto after the expiration of the applicable survival period, except in the case of fraud, which shall survive for the period of any applicable statute of limitations for any Person or Governmental Body to make claims against any party for matters covered thereby.

          (b) For purposes of this Agreement, a “Claim Notice” relating to a particular representation, warranty, covenant or other matter to which a party is entitled to indemnification hereunder shall be deemed to have been given if any party, acting in good faith, delivers to the other party(s) a written notice stating that such party believes that there is or has been a possible breach of such representation, warranty or covenant, or that such party is otherwise entitled to indemnification hereunder, and containing (i) a brief description of the circumstances supporting such party’s belief that there is or has been such a possible breach or that such party is entitled to indemnification, and (ii) to the extent possible, a non-binding, preliminary estimate of the aggregate dollar amount of the actual and potential Damages that have arisen and may arise as a direct or indirect result of such possible breach or other matter giving rise to a right of indemnification.

     10.2 Funding of Escrow.

          (a) At the Closing, Parent shall deposit the Escrow Amount with the Escrow Agent in accordance with the Escrow Agreement. The Escrow Amount shall be withheld from amounts otherwise payable to the holders of the Class A-2 Notes, Class B Notes and Carve-Out Recipients, on a pro rata basis, as reflected on Exhibit I attached hereto. The Escrow Amount will be governed by the terms set forth in the Escrow Agreement and shall be held for the purpose of indemnifying the Parent Indemnitees pursuant to the indemnification provisions set forth in this Section 10.

          (b) The Indemnifying Parties who are entitled to receive shares of Parent Series E-1 Preferred pursuant to Sections 1.5 or 1.6 will be entitled to all rights in respect of the Escrow Amount (such as voting and dividend rights) until their disbursement back to the Parent in satisfaction of indemnification claims. In the event that the Parent completes an initial public offering of shares of its Common Stock pursuant to a registration statement under the Securities Act declared effective by the SEC, such Indemnifying Parties will have the ability to direct the sale of the Escrow Amount (subject to lock-up obligations and other restrictions on transfer) as long as all proceeds from the sales are placed into the escrow for any remaining escrow period and become available for indemnification claims under Section 10.3.

     10.3 Indemnification of Parent Indemnitees.

          (a) Subject to the provisions of this Section 10, from and after the Effective Time, the Parent Indemnitees shall be held harmless and indemnified from and against all Damages that the Parent Indemnitees or any of them may incur based upon, arising out of or otherwise in any way related to:

               (i) any inaccuracy in or breach of any representation or warranty set forth in Sections 2 or 3 as of the date of this Agreement (without giving effect to any update to the Company Disclosure Schedule);

               (ii) any inaccuracy in or breach of any representation or warranty set forth in Sections 2 or 3 as if such representation and warranty had been made on and as of the Closing Date (without giving effect to any update to the Company Disclosure Schedule);

               (iii) any breach of any covenant or obligation of the Company or any of the Signing Noteholders or Carve-Out Recipients contained in this Agreement;

               (iv) any matter identified or referred to in Part 2.21 of the Company Disclosure Schedule;

               (v) (A) all Taxes (or the non-payment thereof) of the Company and each Company Subsidiary attributable to all Pre-Closing Tax Periods, (B) all Taxes of any member of an affiliated, consolidated, combined or unitary group for which the Company or any Company Subsidiary (or any predecessor thereof) is liable, including pursuant to Treasury Regulation Section 1.1502-6 or any analogous or similar state, local, or foreign law or regulation, and (C) any and all Taxes of any person imposed on the Company or any Company Subsidiary

as a transferee or successor, by contract or pursuant to any law, rule, or regulation, which Taxes relate to an event or transaction occurring before the Closing Date;

               (vi) any Dissenting Share Liability;

               (vii) any inaccuracy in or breach of the representations set forth in Section 2.7(c) or, any failure by the Company to satisfy Sections 7.14 or 7.16, any Company Indebtedness not paid by the Company at the Closing or any Company Note Liability; or

               (viii) any Legal Proceeding directly or indirectly relating to any breach, alleged breach, liability or matter of the type referred to in clause “(i),” “(ii),” “(iii),” “(iv),” “(v)”, “(vi)”, or “(vii)” above (including any Legal Proceeding commenced by any Parent Indemnitee for the purpose of enforcing any of his, her or its rights under this Section 10).

          (b) The Company and the Indemnifying Parties acknowledge and agree that, if the Surviving Corporation suffers, incurs or otherwise becomes subject to any Damages as a result of or in connection with any inaccuracy in or breach of any representation, warranty, covenant or obligation or other matter referred to in Section 10.3(a), then (without limiting any of the rights of the Surviving Corporation as a Parent Indemnitee) Parent shall also be deemed, by virtue of its ownership of the stock of the Surviving Corporation, to have incurred Damages as a result of and in connection with such matters.

          (c) The Parent Indemnitees shall not be entitled to any indemnification payment pursuant to Sections 10.3(a)(i) or 10.3(a)(ii) for any inaccuracy in or breach as set forth in such Sections (other than any inaccuracy in or breach of the representations contained in Sections 2.7(c) and 2.23) or pursuant to Section 10.3(a)(viii) to the extent that it relates to the matters referenced in Sections 10.3(a)(i) or 10.3(a)(ii) (other than any inaccuracy in or breach of the representations contained in Sections 2.7(c) and 2.23), until such time as the total amount of all Damages (including the Damages arising from such inaccuracy in or breach and all other Damages arising from any other inaccuracies in or breaches of any representations or warranties set forth in Sections 2 or 3) that have been directly or indirectly suffered or incurred by any one or more of the Parent Indemnitees, or to which any one or more of the Parent Indemnitees has or have otherwise become subject, exceeds $25,000 in the aggregate (the “Threshold Amount”). At such time as the cumulative amount of such Damages exceeds the Threshold Amount in the aggregate, the Parent Indemnitees shall be entitled to recover only the amount of such Damages in excess of the Threshold Amount.

          (d) Except with respect to inaccuracies in or breaches of the Specified Representations, Tax Representations, Benefits Representations and IP Representations or in the case of fraud, willful misrepresentation or intentional misconduct, the Parent Indemnitees shall not be entitled to any indemnification payment pursuant to Sections 10.3(a)(i) or 10.3(a)(ii) for any inaccuracy in or breach as set forth in such Sections (other than any inaccuracy in or breach of the representations contained in Sections 2.7(c) and 2.23) or pursuant to Section 10.3(a)(viii) to the extent that it relates to the matters referenced in Sections 10.3(a)(i) or 10.3(a)(ii) (other than any inaccuracy in or breach of the representations contained in Sections 2.7(c) and 2.23), in excess of an aggregate amount equal to the Escrow Amount (the “Cap Amount”), and in no event shall the liability of any Indemnifying Party exceed such Person’s Pro Rata Share of the

Cap Amount. In all cases (including with respect to inaccuracies in or breaches of the Specified Representations, Tax Representations, Benefits Representations and IP Representations and in the case of fraud, willful misrepresentation or intentional misconduct), the maximum liability shall not exceed $700,000 (the “Maximum Amount”), and in no event shall the liability of any Indemnifying Party exceed such Person’s Pro Rata Share of the Maximum Amount.

     10.4 Indemnification of Company Indemnitees.

          (a) Subject to the provisions of this Section 10, from and after the Effective Time, the Parent shall hold harmless and indemnify the Company Indemnitees from and against all Damages that the Company Indemnitees or any of them may incur based upon, arising out of or otherwise in any way related to:

               (i) any inaccuracy in or breach of any representation or warranty set forth in Section 4 as of the date of this Agreement (without giving effect to any update to the Parent Disclosure Schedule);

               (ii) any inaccuracy in or breach of any representation or warranty set forth in Section 4 as if such representation and warranty had been made on and as of the Closing Date (without giving effect to any update to the Parent Disclosure Schedule);

               (iii) any breach of any covenant or obligation of the Parent contained in this Agreement; or

               (iv) any Legal Proceeding directly or indirectly to any breach, alleged breach, liability or matter of the type referred to in clause “(i),” “(ii),” or “(iii)” above (including any Legal Proceeding commenced by any Company Indemnitee for the purpose of enforcing any of his, her or its rights under this Section 10).

          (b) Subject to Section 10.4(d), the Company Indemnitees shall not be entitled to any indemnification payment pursuant to Sections 10.4(a)(i) or 10.4(a)(ii) for any inaccuracy in or breach as set forth in such Sections or pursuant to Section 10.4(a)(iv) to the extent that it relates to the matters referenced in Sections 10.4(a)(i) or 10.4(a)(ii), until such time as the total amount of all Damages (including the Damages arising from such inaccuracy in or breach and all other Damages arising from any other inaccuracies in or breaches of any representations or warranties set forth in Section 4) that have been directly or indirectly suffered or incurred by any one or more of the Company Indemnitees, or to which any one or more of the Company Indemnitees has or have otherwise become subject, exceeds the Threshold Amount. At such time as the cumulative amount of such Damages exceeds the Threshold Amount in the aggregate, the Company Indemnitees shall be entitled to recover only the amount of such Damages in excess of the Threshold Amount.

          (c) Subject to Section 10.4(d), the Company Indemnitees shall not be entitled to any indemnification payment pursuant to Sections 10.4(a)(i) or 10.4(a)(ii) for any inaccuracy in or breach as set forth in such Sections or pursuant to Section 10.4(a)(iv) to the extent that it relates to the matters referenced in Sections 10.4(a)(i) or 10.4(a)(ii), in excess of an aggregate amount equal to the Cap Amount.

          (d) The limitations set forth in Sections 10.4(b) and 10.4(c) shall not apply in the case of fraud, willful misrepresentation or intentional misconduct, in which case the maximum indemnification payments to which the Company Indemnitees shall be entitled to receive shall be limited to the Maximum Amount.

     10.5 Satisfaction of Parent Indemnitee Indemnification Claims.

          (a) For the purpose of recovering indemnification payments for which the Parent Indemnitees may be entitled under this Section 10, the Parent shall first seek satisfaction of any such indemnification obligations from the property held under the Escrow Agreement. Subject to the limitations contained in this Section 10, if the Parent Indemnitees are not, following such delivery and set-off, completely indemnified (the amount of such Damages which are not so indemnified are referred to as “Unsatisfied Damages”), the Indemnifying Parties, severally and not jointly, shall hold harmless and indemnify the Parent Indemnitees from and against all Unsatisfied Damages, with such recovery to be effected first via delivery of shares of Parent Series E-1 Preferred and only after exhausting all shares of Parent Series E-1 Preferred held by the Indemnifying Parties, if still not completely indemnified, subject to the limitations in this Section 10, in cash.

          (b) To the extent that any indemnification obligations are to be satisfied by delivery of shares of Parent Series E-1 Preferred (or other property) held under the Escrow Agreement, such obligations shall be satisfied by disbursing (a) a number of shares of Parent Series E-1 Preferred to the Parent determined by dividing (i) the aggregate dollar amount of such obligations by (ii) $1.00 (as adjusted as appropriate to reflect any stock split, reverse stock split, stock dividend, recapitalization, merger, reorganization, reclassification or other similar transaction effected by Parent between the Effective Time and the date such obligation is satisfied), or (b) if the shares of Parent Series E-1 Preferred have been sold, the aggregate dollar amount of such obligations. If the shares of Parent Series E-1 Preferred have been converted into shares of Parent Common Stock, then equitable adjustments in the foregoing formula shall be made to take into account the relative conversion ratio.

     10.6 Indemnification Procedures.

          (a) The indemnified party (or parties) shall promptly notify the indemnifying party (or parties) of any third-party claim, demand, action or Legal Proceeding for which indemnification will or may be sought under Sections 10.3 or 10.4 (a “Third Party Claim”), but in no event later than ten (10) business days after receiving notice of such Third Party Claim; provided, however, that the failure to so notify the indemnifying party will not relieve the indemnifying party from liability hereunder in respect of such claim except to the extent the indemnifying party is prejudiced as a result of such failure, including where failure results in losses to the indemnifying party or the forfeiture of substantive rights or defenses that would otherwise be available in the defense of such claim. Such notice shall specify facts reasonably known to the indemnified party (or parties) giving rise to such indemnity rights. The indemnifying party will have the right, at its expense, to assume the defense thereof using counsel reasonably acceptable to the indemnified party. If the indemnifying party elects not to assume the defense or fails to notify the indemnified party within ten (10) business days after delivery of the indemnified party’s notice of such Third Party Claim, that it will assume the

defense, then the indemnified party may employ counsel reasonably satisfactory to the indemnifying party to represent or defend it against any such Third Party Claim and the indemnifying party will pay the reasonable fees and disbursements of such counsel; provided, however, that the indemnifying party shall not, in connection with any Legal Proceeding or any separate but substantially similar Legal Proceedings arising out of the same general allegations, be liable for the fees and expenses of more than one separate firm of attorneys at any time for all indemnified persons, except to the extent that local counsel, in addition to its regular counsel, is required to effectively defend against such Legal Proceeding. If the indemnifying party does assume the defense of such Third Party Claim, the indemnifying party shall have no obligation in respect of the indemnified party’s expenses; provided, that the indemnified party shall have the right to participate in, at its own expense, but not control, the defense of any such Third Party Claim. In connection with any Third Party Claim, the Parties shall cooperate with each other in good faith in such manner to preserve in full (to the extent possible) the confidentiality of all business records and the attorney-client work-product and any other potentially applicable privileges and to render each other assistance as they may reasonably require. No Third Party Claim shall be settled (i) without the prior written consent of the indemnifying party and (ii) without the prior written consent of the indemnified party unless such settlement provides for no relief other than the payment of monetary damages for which the relevant indemnified parties will be indemnified in full.

          (b) As soon as reasonably practicable after becoming aware of a direct claim for indemnification under Sections 10.3 or 10.4 other than a Third Party Claim (a “Direct Claim”), the indemnified party (or parties) shall give a Claim Notice to the indemnifying party (or parties) providing indemnification under this Section 10, as applicable, of such Direct Claim; provided, however, that the failure to so notify the indemnifying party will not relieve the indemnifying party from liability hereunder in respect of such claim except to the extent the indemnifying party is prejudiced as a result of such failure. If the indemnified party is a Parent Indemnitee and is seeking to enforce such claim pursuant to the Escrow Agreement, the indemnifying party shall deliver a copy of the Claim Notice to the Escrow Agent.

          (c) Within twenty (20) days after receipt by the indemnifying party of a Claim Notice, the indemnifying party may deliver to the indemnified party a written response (the “Response Notice”) in which the indemnifying party: (i) agrees that the full Claimed Amount (the “Full Amount”) is owed to the indemnified party (in which case the Response Notice shall be accompanied by a payment by the indemnifying party to the indemnified party of the Claimed Amount, by check or by wire transfer; provided, that if the indemnified party is a Parent Indemnitee and is seeking to enforce such claim pursuant to the Escrow Agreement, the indemnifying party shall also deliver a copy of the Response Notice to the Escrow Agent and instruct the Escrow Agent to disburse the Full Amount to the indemnified party); (ii) agrees that part, but not all, of the Claimed Amount (the “Agreed Amount”) is owed to the indemnified party (in which case the Response Notice shall be accompanied by a payment by the indemnifying party to the indemnified party of the Agreed Amount, by check or by wire transfer; provided, that if the indemnified party is a Parent Indemnitee and is seeking to enforce such claim pursuant to the Escrow Agreement, the indemnifying party shall also deliver a copy of the Response Notice to the Escrow Agent and instruct the Escrow Agent to disburse the Agreed Amount to the indemnified party); or (iii) indicates that no part of the Claimed Amount is owed to the indemnified party. Any part of the Claimed Amount that is not agreed to be released to the

indemnified party pursuant to the Response Notice shall be the “Contested Amount.” If the Response Notice is not received by the indemnified party within such 20-day period, then the indemnifying party shall be conclusively deemed to have agreed that the Full Amount is owed to the indemnified party.

          (d) If the indemnifying party delivers a Response Notice indicating that there is a Contested Amount, the indemnifying party and the indemnified party shall attempt in good faith to resolve the dispute related to the Contested Amount. If the indemnified party and the indemnifying party resolve such dispute, such resolution shall be binding on the indemnifying party and the indemnified party, and if the indemnified party is Parent Indemnitee, a settlement agreement shall be signed by the indemnified party and the indemnifying party and sent to the Escrow Agent.

          (e) In all cases under Section 10, if the indemnified party is a Parent Indemnitee, the indemnifying party shall deliver a copy of the Claim Notice and all other related notices hereunder to the Agent.

     10.7 No Contribution. Each Indemnifying Party waives, acknowledges and agrees that he, she or it shall not have and shall not exercise or assert (or attempt to exercise or assert), any right of contribution, right of indemnity or other right or remedy against the Surviving Corporation in connection with any indemnification obligation or any other liability to which he, she or it may become subject under or in connection with this Agreement.

     10.8 Exercise of Remedies by Parent Indemnitees Other Than Parent. No Parent Indemnitee (other than Parent or any successor thereto or assign thereof) shall be permitted to assert any indemnification claim or exercise any other remedy under this Agreement unless Parent (or any successor thereto or assign thereof) shall have consented to the assertion of such indemnification claim or the exercise of such other remedy.

SECTION 11. Miscellaneous Provisions

     11.1 Agent. The Signing Noteholders and the Carve-Out Recipients and the other parties hereto have agreed that it is desirable to designate a representative to act on behalf of the Signing Noteholders and Carve-Out Recipients for certain limited purposes, as specified herein.

If the Agent shall die, become disabled or otherwise be unable to fulfill his, her or its responsibilities as agent of the Signing Noteholders and Carve-Out Recipients, then the Signing Noteholders and Carve-Out Recipients shall, within ten days after such death or disability, appoint a successor agent and, promptly thereafter, shall notify Parent of the identity of such successor.

               (ii) agrees that each state and federal court located in Wilmington, Delaware shall be deemed to be a convenient forum;

               (iii) agrees not to assert (by way of motion, as a defense or otherwise), in any such Legal Proceeding commenced in any state or federal court located in Wilmington, Delaware, any claim that such party is not subject personally to the jurisdiction of such court, that such Legal Proceeding has been brought in an inconvenient forum, that the venue of such Legal Proceeding is improper or that this Agreement or the subject matter of this Agreement may not be enforced in or by such court; and

               (iv) agrees that a final judgment in any Legal Proceeding in any such court shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

deemed to be a waiver of the right to arbitrate. Furthermore, each party to this Agreement irrevocably and unconditionally agrees to submit any such request exclusively to a state or federal court located in Wilmington, Delaware. Each party to this Agreement hereby irrevocably and unconditionally consents to the personal jurisdiction of such courts and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court any defense that such court does not have personal jurisdiction over him, her or it; each party to this Agreement hereby irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of such request in such courts and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an improper venue or in an inconvenient forum.

          (f) Nothing in this Agreement will limit any party’s right to seek immediate injunctive or other equitable relief whenever the facts or circumstances would permit a party to seek such relief in any court specified in Section 11.10(b).

          (a) No failure on the part of any Person to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of any Person in exercising any power, right, privilege or remedy under this Agreement, shall operate as a waiver of such power, right,

privilege or remedy; and no single or partial exercise of any such power, right, privilege or remedy shall preclude any other or further exercise thereof or of any other power, right, privilege or remedy.

If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

     11.16 Parties in Interest. Except for the provisions of Sections 1.5, 1.6 and 10, none of the provisions of this Agreement is intended to provide any rights or remedies to any Person other than the parties hereto and their respective successors and assigns (if any).
