3.    CONSENT TO ACQUISITION. The consummation of the Datahug Acquisition would violate certain of the terms and provisions of the Loan Documents, including, without limitation, Sections 6.3(a) and 6.9 of the Credit Agreement. Borrower has requested that the Lender Group consent to the Datahug Acquisition, and the Lender Group as of the effective date of this Amendment consents to such Datahug Acquisition so long as at the time of the consummation of the Datahug Acquisition, and giving effect thereto: (i) no Default or Event of Default exists and (ii) Borrower has Availability plus Qualified Cash in an amount equal to or greater than $15,000,000. The foregoing consent shall be effective only in this specific instance and for the specific purpose for which it is given, and this consent shall not entitle Borrower to any other consent or waiver in any similar or other circumstances. The foregoing consent shall be limited precisely as written and shall not be deemed to (a) be a waiver or modification of any other term or condition of the Credit Agreement or any documents related thereto, or (b) prejudice any right or remedy which the Lender Group may now have or may have in the future under or in connection with the Credit Agreement or any documents related thereto.

4.    REPRESENTATIONS AND WARRANTIES. Borrower hereby affirms to Agent, for the benefit of the Lender Group, that, giving effect to this Amendment, all of its representations and warranties set forth in the Agreement are true, complete and accurate in all material respects as of the date hereof (except those which specifically relate to an earlier date).

5.    NO DEFAULTS. Borrower hereby affirms to the Lender Group that, giving effect to this Amendment, no Event of Default has occurred and is continuing as of the date hereof.

7.    [Reserved].

8.    COSTS AND EXPENSES. Borrower shall pay to Agent all of Agent’s documented out-of-pocket costs and expenses (including, without limitation, the reasonable fees and expenses of their counsel, which counsel may include any local counsel deemed necessary, search fees, filing and recording fees, documentation fees, appraisal fees, travel expenses, and other reasonable fees) arising in connection with the preparation, execution, and delivery of this Amendment and all related documents.

9.    COUNTERPARTS; EFFECTIVENESS. This Amendment may be executed in any number of counterparts and by different parties on separate counterparts, each of which when so executed and delivered shall be deemed to be an original. All such counterparts, taken together, shall constitute but one and the same Amendment. This Amendment shall become effective upon the execution of a counterpart of this Amendment by each of the parties hereto and satisfaction of the conditions set forth in Section 6 hereof. Delivery of an executed counterpart of this Amendment by telefacsimile or electronic mail shall be equally as effective as delivery of an original executed counterpart of this Amendment. Any party delivering an executed counterpart of this Amendment by telefacsimile or electronic mail also shall deliver an original executed counterpart of this Amendment, but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Amendment.

10.    FURTHER ASSURANCES. Borrower shall execute and deliver all agreements, documents and instruments, in form and substance reasonably satisfactory to Agent, and take all actions as Agent may reasonably request from time to time to perfect and maintain the perfection and priority of the security interests of Agent in the Collateral and to consummate fully the transactions contemplated under this Amendment and the other Loan Documents.

Except for the amendments to the Credit Agreement expressly set forth herein, the Credit Agreement and the other Loan Documents shall remain unchanged and in full force and effect. The consents, waivers and modifications set forth herein are limited to the specifics hereof, shall not apply with respect to any facts or occurrences other than those on which the same are based, shall neither excuse future non-compliance with the Loan Documents nor operate as a waiver of any Default or Event of Default, shall not operate as a consent to any further or other matter under the Loan Documents and shall not be construed as an indication that any future waiver of covenants or any other provision of the Credit Agreement will be agreed to, it being understood that the granting or denying of any waiver which may hereafter be requested by any Loan Party remains in the sole and absolute discretion of the Agent and the Lenders.

11.3    To the extent that any of the terms and conditions in any of the Loan Documents shall contradict or be in conflict with any of the terms or conditions of the Credit Agreement, after giving effect to this Amendment, such terms and conditions are hereby deemed modified or amended accordingly to reflect the terms and conditions of the Credit Agreement as modified or amended hereby.

11.4    This Amendment is a Loan Document.

11.5    Headings and numbers have been set forth herein for convenience only. Unless the contrary is compelled by the context, everything contained in each Section applies equally to this entire Amendment.

The words “asset” and “property” shall be construed to have the same meaning and effect and to refer to any and all tangible and intangible assets and properties, including cash, securities, accounts, and contract rights. Any reference herein or in any other Loan Document to the satisfaction or repayment in full of the Obligations shall mean the repayment in full in cash or immediately available funds (or, in the case of Letters of Credit or Bank Products, providing Letter of Credit Collateralization or Bank Product Collateralization, as applicable) of all Obligations other than unasserted contingent indemnification Obligations and other than any Bank Product Obligations that, at such time, are allowed by the applicable Bank Product Provider to remain outstanding and that are not required by the provisions of the Credit Agreement to be repaid or cash collateralized.

12.    RELEASE.

12.1    In consideration of the agreements of Agent and each Lender contained herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Borrower, on behalf of itself and its successors, assigns and other legal representatives (Borrower and all such other persons being hereinafter referred to collectively as “Releasors” and individually as a “Releasor”), hereby absolutely, unconditionally and irrevocably releases, remises and forever discharges Agent and each Lender, and their successors and assigns, and their present and former shareholders, affiliates, subsidiaries, divisions, predecessors, directors, officers, attorneys, employees, agents and other representatives (Agent and each Lender and all such other persons being hereinafter referred to collectively as “Releasees” and individually as a “Releasee”), of and from all demands, actions, causes of action, suits, covenants, contracts, controversies, agreements, promises, sums of money, accounts, bills, reckonings, damages and any and all other claims, counterclaims, defenses, rights of set‑off, demands and liabilities whatsoever (individually, a “Claim” and collectively, “Claims”) of every name and nature, known or unknown, suspected or unsuspected,

both at law and in equity, which Releasors may now or hereafter own, hold, have or claim to have against Releasees or any of them for, upon, or by reason of any circumstance, action, cause or thing whatsoever which arises at any time on or prior to the day and date of this Amendment, for or on account of, or in relation to, or in any way in connection with any of the Credit Agreement or any of the other Loan Documents or transactions thereunder or related thereto.

12.3    Borrower, understands, acknowledges and agrees that the release set forth above may be pleaded as a full and complete defense and may be used as a basis for an injunction against any action, suit or other proceeding which may be instituted, prosecuted or attempted in breach of the provisions of such release.

12.4    Borrower, agrees that no fact, event, circumstance, evidence or transaction which could now be asserted or which may hereafter be discovered shall affect in any manner the final, absolute and unconditional nature of the release set forth above.

13.    COVENANT NOT TO SUE. Borrower, on behalf of itself, each Releasor and its successors, assigns and other legal representatives, hereby absolutely, unconditionally and irrevocably, covenants and agrees with and in favor of each Releasee that it will not sue (at law, in equity, in any regulatory proceeding or otherwise) any Releasee on the basis of any Claim released, remised and discharged by Borrower, pursuant to Section 12.1 above. If Borrower, or any of its successors, assigns or other legal representations violates the foregoing covenant, Borrower, for itself and each other Releasor, agrees to pay, in addition to such other damages as any Releasee may sustain as a result of such violation, all attorneys’ fees and costs incurred by any Releasee as a result of such violation.

14.    ENTIRE AGREEMENT. This Amendment, and the terms and provisions hereof, the Credit Agreement and the other Loan Documents constitute the entire understanding and agreement between the parties hereto with respect to the subject matter hereof and supersede any and all prior or contemporaneous

amendments or understandings with respect to the subject matter hereof, whether express or implied, oral or written.

Borrower hereby (a) acknowledges and reaffirms its obligations owing to Agent, the Bank Product Providers, and each other member of the Lender Group under each Loan Document to which it is a party, and (b) agrees that each of the Loan Documents to which it is a party is and shall remain in full force and effect. Borrower hereby (i) further ratifies and reaffirms the validity and enforceability of all of the Liens and security interests heretofore granted, pursuant to and in connection with the Guaranty and Security Agreement or any other Loan Document, to Agent, on behalf and for the benefit of the Lender Group and the Bank Product Providers, as collateral security for the obligations under the Loan Documents in accordance with their respective terms, and (ii) acknowledges that all of such Liens and security interests, and all Collateral heretofore pledged as security for such obligations, continue to be and remain collateral for such obligations from and after the date hereof (including, without limitation, from after giving effect to this Amendment).

17.    CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER; JUDICIAL REFERENCE. THIS AMENDMENT SHALL BE SUBJECT TO THE PROVISIONS REGARDING CHOICE OF LAW AND VENUE, JURY TRIAL WAIVER, AND JUDICIAL REFERENCE SET FORTH IN SECTION 12 OF THE CREDIT AGREEMENT, AND SUCH PROVISIONS ARE INCORPORATED HEREIN BY THIS REFERENCE, MUTATIS MUTANDIS.

18.    SEVERABILITY. In case any provision in this Amendment shall be invalid, illegal or unenforceable, such provision shall be severable from the remainder of this Amendment and the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.
