JOINDER AND FOURTH LOAN MODIFICATION AGREEMENT

     This Joinder and Fourth Loan Modification Agreement (this “Loan Modification Agreement”) is entered into as of April 7, 2010, by and among SILICON VALLEY BANK, a California corporation, with its principal place of business at 3003 Tasman Drive, Santa Clara, California 95054 and with a loan production office located at 380 Interlocken Crescent, Suite 600, Broomfield, Colorado 80021 (“Bank”), TRUSTWAVE HOLDINGS, INC., a Delaware corporation (“Holdings”), TRUSTWAVE INTERMEDIATE, INC., a Delaware corporation (“Intermediate”), and TW VERICEPT CORPORATION, a Delaware corporation (formerly known as “TrustWave Acquisition, Inc.,” “Vericept” and individually and collectively, jointly and severally, with Holdings, and Intermediate, “Existing Borrower”).

1. DESCRIPTION OF EXISTING INDEBTEDNESS AND OBLIGATIONS. Among other indebtedness and obligations which may be owing by Borrower to Bank, Borrower is indebted to Bank pursuant to a loan arrangement dated as of August 19, 2009, evidenced by, among other documents, a certain Amended and Restated Loan and Security Agreement dated as of August 19, 2009 between Borrower and Bank, as amended by a First Loan Modification Agreement dated October 19, 2009 between Borrower and Bank, as amended by a Consent and Second Loan Modification Agreement dated January 6, 2010 between Borrower and Bank, and as further amended by a Consent and Third Loan Modification Agreement dated March 1, 2010 between Borrower and Bank (as amended, the “Loan Agreement”). Capitalized terms used but not otherwise defined herein shall have the same meaning as in the Loan Agreement.

2. DESCRIPTION OF COLLATERAL. Repayment of the Obligations is secured by the Collateral as described in the Loan Agreement and the Intellectual Property Collateral as described in a certain Intellectual Property Security Agreement dated August 19, 2009, by Vericept in favor of Bank (the “IP Security Agreement and together with any other collateral security granted to Bank, the “Security Documents”). Hereinafter, the Security Documents, together with all other documents evidencing or securing the Obligations shall be referred to as the “Existing Loan Documents”.

3. JOINDER TO LOAN AGREEMENT. The undersigned, TrustWave Government Solutions, Inc., a Delaware corporation and a wholly-owned subsidiary of Holdings, (hereinafter, the “New Borrower”, and, together with the Existing Borrower, jointly, severally, individually and collectively, the “Borrower”), hereby joins the Loan Agreement and each of the Loan Documents, and agrees to comply with and be bound by all of the terms, conditions and covenants of the Loan Agreement and Loan Documents, as if it were originally named a “Borrower” therein. Without limiting the generality of the preceding sentence, New Borrower agrees that it will be jointly and severally liable, together with Existing Borrower, for the payment and performance of all obligations and liabilities of Borrower under the Loan Agreement, including, without limitation, the Obligations. Either Borrower may, acting singly, request Credit Extensions pursuant to the Loan Agreement. Each Borrower hereby appoints the other as agent for the other for all purposes hereunder, including with respect to requesting Credit Extensions pursuant to the Loan Agreement. Each Borrower hereunder shall be obligated to repay all Credit Extensions made pursuant to the Loan Agreement, regardless of which Borrower actually receives said Credit Extension, as if each Borrower hereunder directly received all Credit Extensions.

4. SUBROGATION AND SIMILAR RIGHTS. Each Borrower waives any suretyship defenses available to it under the Code or any other applicable law. Each Borrower waives any right to require Bank to: (i) proceed against either Borrower or any other person; (ii) proceed against or exhaust any security; or (iii) pursue any other remedy. Bank may exercise or not exercise any right or remedy it has against either Borrower or any security it holds (including the right to foreclose by judicial or non-judicial sale) without affecting either Borrower’s liability. Notwithstanding any other provision of this Loan Modification Agreement, the Loan Agreement, or other Loan Documents, each Borrower irrevocably waives all rights that it may have at law or in equity (including, without limitation, any law subrogating Borrower to the rights of Bank under the Loan Agreement) to seek contribution, indemnification or any other form of reimbursement from the other Borrower, or any other Person now or hereafter

primarily or secondarily liable for any of the Obligations, for any payment made by Borrower with respect to the Obligations in connection with the Loan Agreement or otherwise and all rights that it might have to benefit from, or to participate in, any security for the Obligations as a result of any payment made by Borrower with respect to the Obligations in connection with the Loan Agreement or otherwise. Any agreement providing for indemnification, reimbursement or any other arrangement prohibited under this section shall be null and void. If any payment is made to a Borrower in contravention of this section, such Borrower shall hold such payment in trust for Bank and such payment shall be promptly delivered to Bank for application to the Obligations, whether matured or unmatured.

5. GRANT OF SECURITY INTEREST. To secure the prompt payment and performance of all of the Obligations, New Borrower hereby grants to Bank a continuing lien upon and security interest in all of New Borrower’s now existing or hereafter arising rights and interest in the Collateral, whether now owned or existing or hereafter created, acquired, or arising, and wherever located, including, without limitation, all of New Borrower’s assets, and all New Borrower’s books relating to the foregoing and any and all claims, rights and interests in any of the above and all substitutions for, additions, attachments, accessories, accessions and improvements to and replacements, products, proceeds and insurance proceeds of any or all of the foregoing. New Borrower further covenants and agrees that by its execution hereof it shall provide all such information, complete all such forms, and take all such actions, and enter into all such agreements, in form and substance reasonably satisfactory to Bank that are reasonably deemed necessary by Bank in order to grant a valid, perfected security interest to Bank in the Collateral. New Borrower hereby authorizes Bank to file financing statements, without notice to Borrower, with all appropriate jurisdictions in order to perfect or protect Bank’s interest or rights hereunder, including a notice that any disposition of the Collateral, by either Borrower or any other Person, shall be deemed to violate the rights of Bank under the Code.

6. REPRESENTATIONS AND WARRANTIES. New Borrower hereby represents and warrants to Bank that all representations and warranties in the Loan Documents made on the part of Existing Borrower are true and correct on the date hereof with respect to New Borrower, with the same force and effect as if New Borrower were named as “Borrower” in the Loan Documents in addition to Existing Borrower.

7. DELIVERY OF DOCUMENTS. New Borrower hereby agrees that the following documents shall be delivered to Bank prior to or concurrently with this Loan Modification Agreement, each in form and substance satisfactory to Bank:

	A.		a certificate of the Secretary of New Borrower with respect to certificate of incorporation, by-laws, incumbency and resolutions authorizing the execution and delivery of this Loan Modification Agreement;
	B.		a long form certificate of the Secretary of State of Delaware (certified within the prior 30 days) as to New Borrower’s existence and good standing and listing all applicable organizational documents filed by New Borrower with the Secretary of State of Delaware;

	G.		evidence satisfactory to Bank that the insurance policies required by Section 6.5 to the Loan Agreement are in full force and effect, together with appropriate evidence showing lender loss payable and/or additional insured clauses or endorsements in favor of Bank; and

NOTWITHSTANDING THE FOREGOING, BANK SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH BANK DEEMS NECESSARY OR APPROPRIATE IN ORDER TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE BANK’S RIGHTS AGAINST BORROWER OR ITS PROPERTY.
