At any time and from time to time, upon the written request of Bank, and at the sole expense of Grantor, Grantor shall promptly and duly execute and deliver any and all such further instruments and documents and take such further action as Bank may reasonably deem desirable to obtain the full benefits of this Agreement and of the rights and powers herein granted, including, without limitation, (i) to secure all consents and approvals necessary or appropriate for the grant of a security interest to Bank in any Collateral held by Grantor or in which Grantor has any rights not heretofore assigned, (ii) filing any financing or continuation statements under the Code with respect to the security interests granted hereby, (iii) transferring Collateral to Bank’s possession (if a security interest in such Collateral can be perfected by possession), (iv) placing the interest of Bank as lienholder on the certificate of title (or other evidence of ownership) of any vehicle owned by Grantor or in or with respect to which Grantor holds a beneficial interest and (v) obtaining, for each Collateral Location with Collateral with an aggregate book value in excess of Two Hundred Fifty Thousand Dollars ($250,000) that is not owned by Grantor, a landlord subordination agreement, collateral access agreement or bailment waiver, executed by the landlord, warehouseman or bailee of such location, as applicable, together with a copy of the lease, warehouse or bailment agreement for each such location; provided, however, the aggregate book value of Collateral at Collateral Locations not subject to the foregoing requirements shall not exceed Five Hundred Thousand Dollars ($500,000). Grantor also hereby authorizes Bank to file any such financing or continuation statement. If any amount payable under or in connection with any of the Collateral is or shall become evidenced by any Instrument, such Instrument, other than checks and notes received in the ordinary course of business, shall be duly endorsed in a manner reasonably satisfactory to Bank and delivered to Bank promptly upon Grantor’s receipt thereof.

(r) Minimum Cash. On February 22, 2012, and at all times thereafter, Grantor shall maintain a balance of Grantor’s unrestricted cash and cash equivalents at Bank of not less Five Hundred Thousand Dollars ($500,000).

(s) Evidence of Mergers. Within fourteen (14) days after the Closing Date, Grantor shall provide, or cause to be provided, to Bank, evidence in form and detail acceptable to Bank in Bank’s reasonable discretion that Grantor acquired 100% of the equity interests of (i) TENROX Inc., a Delaware corporation, and (ii) TENROX Ltd., a private company limited by shares formed under the laws of England and Wales.

5. Events of Default. The occurrence of any Event of Default under the Loan Agreement or Grantor’s breach of any term provision, covenant warranty or representation under this Agreement, or under any other document, instrument or agreement entered into between Grantor and Bank, as the same may be amended modified or supplemented from time to time, shall constitute an “Event of Default” under this Agreement.

6. Remedies. Upon the occurrence and during the continuance of an Event of Default, Bank shall have all rights, privileges, powers and remedies provided by law, including, but not limited to, exercise of any or all of the following remedies only during the continuance of an Event of Default.

(a) Bank may declare all Secured Obligations to be immediately due and payable, and thereupon all such amounts shall be and become immediately due and payable to the Bank.

(b) Bank may dispose of the Collateral in accordance with applicable law.

(c) Bank may use, operate, consume and sell the Collateral in its possession as appropriate for the purpose of performing Grantor’s obligations with respect thereto to the extent necessary to satisfy the obligations of Grantor.

(d) Bank may transfer to or to register on the books of any Issuer (or of any other Person maintaining records with respect to the Pledged Interests) in the name of Bank or any of its nominees any or all of the Pledged Interests.

(e) All payments received and amounts realized by Bank shall be promptly applied and distributed by the Bank in the following order of priority:

(i) first, to the payment of all costs and expenses, including legal expenses and reasonable attorneys fees, incurred or made hereunder by Bank, including any such costs and expenses of foreclosure or suit, if any, and of any sale or the exercise of any other remedy under this Section 6, and of all taxes, assessments or liens superior to the lien granted under this Agreement; and

(ii) second, to the payment to Bank of the amount then owing under the Secured Obligations; and

(iii) third, to Grantor, to the extent permitted under applicable law.

7. Sale of Pledged Interests.

(a) Grantor acknowledges that the sale by Bank of any Pledged Interests pledged by it pursuant to the terms hereof in compliance with the Securities Laws may require strict limitations as to the manner in which Bank or any subsequent transferee of the Pledged Interests may dispose thereof. Grantor acknowledges and agrees that in order to protect Bank’s interest it may be necessary to sell the Pledged Interests at a price less than the maximum price attainable if a sale were delayed or were made in another manner, such as a public offering under the Securities Laws. Grantor has no objection to any sale in such a manner and agrees that Bank shall have no obligation to obtain the maximum possible price for the Pledged Interests. Without limiting the generality of the foregoing, Grantor agrees that, upon the occurrence and during the continuation of an Event of Default, Bank may, subject to applicable law, from time to time attempt to sell all or any part of the Pledged Interests by a private placement, restricting the bidders and prospective purchasers to those who will represent and agree that they are purchasing for investment only and not for distribution. In so doing, Bank may solicit offers to buy the Pledged Interests or any part thereof for cash, from a limited number of investors deemed by Bank, in its reasonable judgment, to be institutional investors or other responsible parties who might be interested in purchasing the Pledged Interests. If Bank shall solicit such offers in accordance with the terms hereof and applicable Securities Laws, then the acceptance by Bank of one of the offers shall be deemed to be a commercially reasonable method of disposition of the Pledged Interests.

(b) If Bank shall determine to exercise its right to sell all or any portion of the Pledged Interests pursuant to this Section, Grantor agrees that, upon request of Bank, Grantor will, at its own expense, as applicable, execute and deliver to Bank or other Person, as directed by Bank, or cause the officers and directors of Issuer to execute and deliver, any and all documents and instruments which, in Bank’s reasonable judgment, may be necessary or appropriate in order to transfer or to more effectively transfer the Pledged Interests or otherwise enforce Bank’s rights hereunder.

8. Power of Attorney. Effective only upon the occurrence and during the continuance of an Event of Default, Grantor hereby irrevocably appoints Bank (and any of Bank’s designated officers, or employees) as Grantor’s true and lawful attorney to: (a) send requests for verification of Accounts or notify account debtors of Bank’s security interest in the Accounts; (b) endorse Grantor’s name on any checks or other forms of payment or security that may come into Bank’s possession; (c) sign Grantor’s name on any invoice or ▇▇▇▇ of lading relating to any Account, drafts against account debtors, schedules and assignments of Accounts, verifications of Accounts, and notices to account debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all claims under and decisions with respect to Grantor’s policies of insurance; (f) settle and adjust disputes and claims respecting the accounts directly with account debtors, for amounts and upon terms which Bank determines to be reasonable; (g) file Grantor’s tax returns and related documents with the appropriate governmental authority; (h) enter into a short-form intellectual property security agreement consistent with the terms of this Agreement for recording purposes only or modify, in its sole discretion, any intellectual property security agreement entered into between Grantor and Bank without first obtaining Grantor’s approval of or signature to such modification by amending the exhibits or schedules thereof, as appropriate, to include reference to any right, title or interest in any Copyrights, Patents, Trademarks or other intellectual property collateral acquired by Grantor after the execution hereof or to delete any reference to any right, title or interest in any Copyrights, Patents, Trademarks or other Intellectual Property Collateral in which Grantor no longer has or claims to have any right, title or interest; and (i) file, in its sole discretion, one or more financing statements, financing change statements or continuation statements and amendments thereto, relative to any of the Collateral without the signature of Grantor where permitted by law; provided Bank may exercise such power of attorney to sign the name of Grantor on any of the documents described in clauses (h) and (i) above, regardless of whether an Event of Default has occurred. The appointment of Bank as Grantor’s attorney in fact, and each and every one of Bank’s rights and powers, being coupled with an interest, is irrevocable until all of the Secured Obligations have been fully repaid and performed and Bank’s obligation to provide advances hereunder is terminated.

9. Remedies Cumulative. Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative. Bank shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Bank of one right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on Borrower’s part shall be deemed a continuing waiver. No delay by Bank shall constitute a waiver, election, or acquiescence by it. No waiver by Bank shall be effective unless made in a written document signed on behalf of Bank and then shall be effective only in the specific instance and for the specific purpose for which it was given.

10. Amendment of Loan Documents. Grantor authorizes Bank, without notice or demand and without affecting its liability hereunder, from time to time to (a) renew, extend, or (with the approval of Borrower) otherwise change the terms of any Loan Document, or any part thereof; (b) take and hold security for the payment of any Loan Document, and exchange, enforce, waive and release any such security; and (c) apply such security and direct the order or manner of sale thereof as Bank in its sole discretion may determine.

11. Grantor Waivers. Grantor waives any right to require Bank to (a) proceed against Borrower, any guarantor or any other person; (b) proceed against or exhaust any security held from Borrower; (c) marshal any assets of Borrower; or (d) pursue any other remedy in Bank’s power whatsoever. Bank may, at its election, release, exchange, modify, enforce and otherwise exercise or decline or fail to exercise any right or remedy it may have against Borrower, any guarantor or any security held by Bank, including without limitation the right to foreclose upon any such security by judicial or nonjudicial sale, without affecting or impairing in any way the liability of Grantor hereunder. Grantor is not relying upon any guaranty which Bank has or may have or assets in which Bank has or may have a lien or security interest for payment of the Secured Obligations. Grantor agrees that no security or guaranty now or later held by Bank for the payment of any Secured Obligations, whether from Borrower, any guarantor, or otherwise, and whether in the nature of a security interest, pledge, lien, assignment, setoff, suretyship, guaranty, indemnity, insurance or otherwise, shall affect in any manner the unconditional pledge of Grantor under this Agreement. Grantor waives any defense arising by reason of any disability or other defense of Borrower or by reason of the cessation from any cause whatsoever of the liability of Borrower. Grantor waives any setoff, defense or counterclaim that Borrower may have against Bank. Grantor waives any defense arising out of the absence, impairment or loss of any right of reimbursement or subrogation or any other rights against Borrower. Until all Secured Obligations have been satisfied, Grantor shall have no right of subrogation or reimbursement, contribution or other rights against Borrower, and Grantor waives any right to enforce any remedy that Bank now has or may hereafter have against Borrower. Grantor waives all rights to participate in any security now or hereafter held by Bank. Grantor waives all presentments, demands for performance, notices of nonperformance, protests, notices of protest, notices of dishonor, and notices of acceptance of this Agreement and of the existence, creation, or incurring of new or additional indebtedness. Grantor assumes the responsibility for being and keeping itself informed of the financial condition of Borrower and of all other circumstances bearing upon the risk of nonpayment of any indebtedness or nonperformance of any obligation of Borrower, warrants to Bank that it will keep so informed, and agrees that absent a request for particular information by Grantor, Bank shall have no duty to advise Grantor of information known to Bank regarding such condition or any such circumstances. Until all Obligations have been satisfied, Grantor waives the benefits of California Civil Code sections 2799, 2809, 2810, 2815, 2819, 2820, 2821, 2822, 2838, 2839, 2845, 2847, 2848, 2849, 2850, 2899 and 3433.

12. Borrower Insolvency. If Borrower becomes insolvent or is adjudicated bankrupt or files a petition for reorganization, arrangement, composition or similar relief under any present or future provision of the United States Bankruptcy Code, or if such a petition is filed against Borrower, and in any such proceeding some or all of any indebtedness or obligations under the Loan Documents are terminated or rejected or any obligation of Borrower is modified or abrogated, or if Borrower’s obligations are otherwise avoided for insolvency, bankruptcy or any similar reason, Grantor agrees that Grantor’s liability hereunder shall not thereby be affected or modified and such liability shall continue in full force and effect as if no such action or proceeding had occurred. This Agreement shall continue to be effective or be reinstated, as the case may be, if any payment must be returned by Bank upon the insolvency, bankruptcy or reorganization of Borrower, Grantor, any other person, or otherwise, as though such payment had not been made.

13. Notices. Unless otherwise provided in this Agreement, all notices or demands by any party relating to this Agreement or any other agreement entered into in connection herewith shall be in writing and (except for financial statements and other informational documents which may be sent by first-class mail, postage prepaid) shall be personally delivered or sent by a recognized overnight delivery service, certified mail, postage prepaid, return receipt requested, or by telefacsimile to Grantor or to Bank, as the case may be, at its addresses set forth below:

The parties hereto may change the address at which they are to receive notices hereunder, by notice in writing in the foregoing manner given to the other. Failure to deliver a copy of any notice or demand to a Person who is not a party to this Agreement shall not render ineffective any notice or demand otherwise delivered to a party to this Agreement in accordance with this Section.

14. Choice of Law and Venue; Jury Trial Waiver.

This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of California, without regard to principles of conflicts of law. Each of the parties hereto hereby submits to the exclusive jurisdiction of the state and Federal courts located in the County of Santa ▇▇▇▇▇, State of California. THE UNDERSIGNED ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED UNDER CERTAIN CIRCUMSTANCES. TO THE EXTENT PERMITTED BY LAW, EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY OTHER DOCUMENT, INSTRUMENT OR AGREEMENT BETWEEN THE UNDERSIGNED PARTIES.

15. Reference Provision.

(a) In the event the Jury Trial Waiver set forth above is not enforceable, the parties elect to proceed under this Judicial Reference Provision.

(b) With the exception of the items specified in clause (c), below, any controversy, dispute or claim (each, a “Claim”) between the parties arising out of or relating to this Agreement or any other document, instrument or agreement between the undersigned parties (collectively in this Section, the “Comerica Documents”), will be resolved by a reference proceeding in California in accordance with the provisions of Sections 638 et seq. of the California Code of Civil Procedure (“CCP”), or their successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to the reference proceeding. Except as otherwise provided in the Comerica Documents, venue for the reference proceeding will be in the state or federal court in the county or district where the real property involved in the action, if any, is located or in the state or federal court in the county or district where venue is otherwise appropriate under applicable law (the “Court”).

(c) The matters that shall not be subject to a reference are the following: (i) nonjudicial foreclosure of any security interests in real or personal property, (ii) exercise of self-help remedies (including, without limitation, set-off), (iii) appointment of a receiver and (iv) temporary, provisional or ancillary remedies (including, without limitation, writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). This reference provision does not limit the right of any party to exercise or oppose any of the rights and remedies described in clauses (i) and (ii) or to seek or oppose from a court of competent jurisdiction any of the items described in clauses (iii) and (iv). The exercise of, or opposition to, any of those items does not waive the right of any party to a reference pursuant to this reference provision as provided herein.

(d) The referee shall be a retired judge or justice selected by mutual written agreement of the parties. If the parties do not agree within ten (10) days of a written request to do so by any party, then, upon request of any party, the referee shall be selected by the Presiding Judge of the Court (or his or her representative). A request for appointment of a referee may be heard on an ex parte or expedited basis, and the parties agree that irreparable harm would result if ex parte relief is not granted. Pursuant to CCP § 170.6, each party shall have one peremptory challenge to the referee selected by the Presiding Judge of the Court (or his or her representative).

(e) The parties agree that time is of the essence in conducting the reference proceedings. Accordingly, the referee shall be requested, subject to change in the time periods specified herein for good cause shown, to (i) set the matter for a status and trial-setting conference within fifteen (15) days after the date of selection of the referee, (ii) if practicable, try all issues of law or fact within one hundred twenty (120) days after the date of the conference and (iii) report a statement of decision within twenty (20) days after the matter has been submitted for decision.

(f) The referee will have power to expand or limit the amount and duration of discovery. The referee may set or extend discovery deadlines or cutoffs for good cause, including a party’s failure to provide requested discovery for any reason whatsoever. Unless otherwise ordered based upon good cause shown, no party shall be entitled to “priority” in conducting discovery, depositions may be taken by either party upon seven (7) days written notice, and all other discovery shall be responded to within fifteen (15) days after service. All disputes relating to discovery which cannot be resolved by the parties shall be submitted to the referee whose decision shall be final and binding.

(g) Except as expressly set forth herein, the referee shall determine the manner in which the reference proceeding is conducted including the time and place of hearings, the order of presentation of evidence, and all other questions that arise with respect to the course of the reference proceeding. All proceedings and hearings conducted before the referee, except for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing conducted before the referee, and the referee will be provided a courtesy copy of the transcript. The party making such a request shall have the obligation to arrange for and pay the court reporter. Subject to the referee’s power to award costs to the prevailing party, the parties will equally share the cost of the referee and the court reporter at trial.

(h) The referee shall be required to determine all issues in accordance with existing case law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of California will be applicable to the reference proceeding. The referee shall be empowered to enter equitable as well as legal relief, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a court proceeding, including without limitation motions for summary judgment or summary adjudication. The referee shall issue a decision at the close of the reference proceeding which disposes of all claims of the parties that are the subject of the reference. Pursuant to CCP § 644, such decision shall be entered by the Court as a judgment or an order in the same manner as if the action had been tried by the Court and any such decision will be final, binding and conclusive. The parties reserve the right to appeal from the final judgment or order or from any appealable decision or order entered by the referee. The parties reserve the right to findings of fact, conclusions of laws, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial, if granted, is also to be a reference proceeding under this provision.

(i) If the enabling legislation which provides for appointment of a referee is repealed (and no successor statute is enacted), any dispute between the parties that would otherwise be determined by reference procedure will be resolved and determined by arbitration. The arbitration will be conducted by a retired judge or justice, in accordance with the California Arbitration Act § 1280 through § 1294.2 of the CCP as amended from time to time. The limitations with respect to discovery set forth above shall apply to any such arbitration proceeding.

(j) THE PARTIES RECOGNIZE AND AGREE THAT ALL CONTROVERSIES, DISPUTES AND CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A REFEREE AND NOT BY A JURY. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, AGREES THAT THIS REFERENCE PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN OR AMONG THEM ARISING OUT OF OR IN ANY WAY RELATED TO, THIS AGREEMENT OR THE OTHER COMERICA DOCUMENTS.

16. Amalgamation of Borrower. Within one Business Day of the date hereof, Silverback Two Canada Merger Corporation will amalgamate with its wholly owned subsidiary, TENROX Inc., a Canadian corporation, with TENROX Inc. as the resulting amalgamated entity (the “Amalgamation”). Upon the completion of the Amalgamation, TENROX Inc. will be the Borrower under the Loan Agreement and all other Loan Documents and all references in this Agreement and the other Loan Documents to “Silverback Two Canada Merger Corporation” shall refer to “TENROX Inc.”, the amalgamated entity.

17. General Provisions.

(a) Successors and Assigns. This Agreement shall bind and inure to the benefit of the respective successors and permitted assigns of each of the parties; provided, however, that neither this Agreement nor any rights hereunder may be assigned by Grantor without Bank’s prior written consent, which consent may be granted or withheld in Bank’s sole discretion. Bank shall have the right without the consent of or notice to Grantor to sell, transfer, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights and benefits hereunder.

(b) Indemnification. Grantor shall defend, indemnify and hold harmless Bank and its officers, employees, and agents against: (a) all obligations, demands, claims, and liabilities claimed or asserted by any other party in connection with Grantor’s failure to comply with the terms of this Agreement; and (b) all losses or Bank Expenses (as defined in the Loan Agreement) in any way suffered, incurred, or paid by Bank as a result of or in any way arising out of, following, or consequential to Grantor’s failure to comply with the terms of this Agreement (including without limitation reasonable attorneys fees and expenses), except for losses caused by Bank’s gross negligence or willful misconduct.

(d) Severability of Provisions. Each provision of this Agreement shall be severable from every other provision of this Agreement for the purpose of determining the legal enforceability of any specific provision.

(e) Amendments in Writing, Integration. This Agreement cannot be amended or terminated orally. All prior agreements, understandings, representations, warranties, and negotiations between the parties hereto with respect to the subject matter of this Agreement, if any, are merged into this Agreement and the Loan Documents.

(f) Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Agreement.

(g) Survival. All covenants, representations and warranties made in this Agreement shall continue in full force and effect so long as any Secured Obligations remain outstanding or Bank has any obligation to make Credit Extensions to Borrower. The obligations of Grantor to indemnify Bank with respect to the expenses, damages, losses, costs and liabilities described in this Agreement shall survive until all applicable statute of limitations periods with respect to actions that may be brought against Bank have run.

AMENDMENT TO PLEDGE AND SECURITY AGREEMENT

This Amendment to Pledge and Security Agreement (“Amendment”), is made, delivered, and effective as of March 5, 2012 (“Effective Date”) between SILVERBACK ENTERPRISE GROUP, INC., a Delaware corporation (“Grantor”) and COMERICA BANK (“Bank”).

RECITALS

A. Grantor and Bank are parties to that certain Pledge and Security Agreement dated as of February 10, 2012 (the “Security Agreement”).

B. Grantor and Bank desire to amend the Security Agreement as set forth herein.

NOW, THEREFORE, in consideration of the premises and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, Grantor and Bank agree as follows:

Section 2(b) of the Security Agreement is amended and restated to read in its entirety as follows:

“(b) Notwithstanding the foregoing, the security interest granted by Grantor over the Pledged Interests where the Issuer is a Foreign Subsidiary, shall:

(i) Be a pledge of 100% of the aggregate issued and outstanding equity interests of such Issuer to secure (x) the Obligations, and (y) any Grantor Obligations arising under that certain Unconditional Guaranty dated as of even date herewith by Grantor in favor of Bank;

(ii) Be limited to a pledge of 65% (or such lesser percentage owned by Grantor) of the aggregate issued and outstanding voting equity interests of such Issuer (determined based on the total voting rights represented by such equity interests) to secure any Grantor Obligations other than any Grantor Obligations arising under that certain Unconditional Guaranty dated as of even date herewith by Grantor in favor of Bank.”

Grantor acknowledges and agrees that except as expressly amended in this Amendment, the Security Agreement, as amended, remains in full force and effect, subject to no setoff, defense or counterclaim.

Grantor affirms its obligations to Bank under the Security Agreement.

All the terms used in this Amendment which are defined in the Security Agreement shall have the same meaning as used in the Security Agreement, unless otherwise defined in this Amendment.
