(d) Borrower will promptly (and in any event within five (5) calendar days) notify Lender upon the filing, either by Borrower or through any agent, employee, licensee or designee, of any Copyright registration with the United States Copyright Officer with respect to any proprietary software of Borrower or any other property that is subject to registration with the United States Copyright Office;

(e) Borrower will take all necessary steps in any proceeding before the United States Patent and Trademark Office, the Untied Sates Copyright Office or any similar office or agency in any other country or any political subdivision thereof, to diligently prosecute or maintain, as applicable, each application and registration of the Patents, Trademarks and Copyrights, including filing of renewals, affidavits of use, affidavits of incontestability and opposition, interference and cancellation proceedings (except to the extent that dedication, abandonment or invalidation is permitted hereunder);

(f) Borrower shall (i) use proper statutory notice in connection with its use of the Patents, Trademarks and Copyrights, (ii) maintain consistent standards of quality in its manufacture of products sold under the Trademarks or provision of services in connection with the Trademarks, and (iii) take all steps necessary to protect the secrecy and the validity under applicable law of all material trade secrets;

(g) Borrower agrees that if it learns of any use by any Person of any term or design likely to cause confusion with any Trademark, Borrower shall promptly notify Lender of such use and of all steps taken and to be taken to remedy any infringement of any Trademark; and

(h) Borrower shall maintain with each employee who may have access to the trade secrets of Borrower an agreement by which such employee agrees not to disclose such trade secrets and with each employee who may be the inventor of patentable inventions (invented within the scope of such employee’s employment) an invention assignment agreement requiring such employee to assign all rights to such inventions, including Patents and Patent applications, to Borrower and further requiring such employee to cooperate fully with Borrower, its successors in interest, including Lender, and their counsel, in the prosecution of any Patent application or in any litigation involving the invention, whether such cooperation is required during such employee’s employment with Borrower or after the termination of such employment.

(i) For the purpose of enabling Lender to exercise rights and remedies under Section 9 at such time as Lender shall be lawfully entitled to exercise such rights and remedies, and for no other purpose, Borrower hereby grants to Lender, to the extent assignable, an irrevocable, non-exclusive license (exercisable without payment of royalty or other compensation to Borrower) to use, assign, license or sublicense any of the Intellectual Property now owned or hereafter acquired by Borrower, wherever the same may be located, including in

such license reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer programs used for the compilation or printout thereof; provided, however, such license shall only be effective during the existence of an Event of Default.

Borrower covenants and agrees that, so long as any credit hereunder shall be available and until payment in full of all outstanding Obligations, and for so long as Lender may have any commitment to make Advances hereunder, Borrower will not do any of the following without the prior written consent of Lender; provided, however, Borrower may enter into other transactions to permit the repayment of Obligations after a Lender Event of Default:

(a) Dispositions. Convey, sell, lease, transfer or otherwise dispose of (collectively, “Transfer”), or permit any of its Subsidiaries to Transfer, all or any part of its business or property, other than: (i) Transfers of Inventory or other property that do not in the aggregate have a fair market value in excess of $5,000 and which is consistent with Borrower’s past business practices and occurs in the ordinary course of business; (ii) Transfers of non-exclusive licenses and similar arrangements for the use of the property of Borrower or its Subsidiaries; and (iii) Transfers of worn-out or obsolete Equipment or new Equipment financed by other vendors.

(b) Change in Business. Engage in any business, or permit any of its Subsidiaries to engage in any business, other than the business currently engaged in by Borrower and any business substantially similar or related thereto (or incidental thereto) or suffer a change in control other than the distribution of Borrower’s stock from NexQL Holdings to its members. Borrower will not, without 30-days prior written notification to Lender, relocate its principal office.

(c) Mergers or Acquisitions. Merge or consolidate, or permit any of its subsidiaries to merge or consolidate, with or into any other business organization, or acquire, or permit any of its Subsidiaries to acquire, all or substantially all of the capital stock or property of another Person in a transaction, or enter into any or become bound to effect any Liquidation Event.

(d) Indebtedness. Create, incur, assume or be or remain liable with respect to any indebtedness, or permit any Subsidiary so to do, other than Permitted Indebtedness.

(e) Encumbrances. Create, incur, assume or suffer to exist any Lien with respect to any of its property, or assign or otherwise convey any right to receive income, including the sale of any Accounts, or permit any of its Subsidiaries so to do, except for Permitted Liens.

(f) Investments. Directly or indirectly acquire or own, or make any Investment in any Person, or permit any of its Subsidiaries so to do, other than Permitted Investments.

(g) Transactions with Affiliates. Directly or indirectly enter into or permit to exist any material transaction with any Affiliate of Borrower (other than Lender) or transfer, pay, loan or otherwise obligate Borrower to give cash, services, assets or other items of value to NexQL Holdings or to its members or commit to do any of the preceding after the date hereof.

(h) Intellectual Property Agreements. Borrower shall not permit the inclusion in any material contract to which it becomes a party of any provisions that could or might in any way prevent the creation of a security interest in Borrower’s rights and interests in any property included within the definition of the Intellectual Property acquired under such contracts, except to the extent that such provisions are necessary in Borrower’s exercise of its reasonable business judgment.

(i) Subordinated Debt. Make any payment in respect of any Subordinated Debt, or permit any of its Subsidiaries to make any such payment, except in compliance with the terms of such Subordinated Debt, or amend any provision contained in any documentation relating to the Subordinated Debt without Lender’s prior written consent.

Any one or more of the following events shall constitute a “Borrower Event of Default” under this Agreement:

(a) Payment Default. If Borrower fails to pay the principal of, or any interest on, the Advance, when due and payable on the Maturity Date; or fails to pay any portion of any other Obligations not constituting such principal or interest, including without limitation Lender Expenses, within 30 days of receipt by Borrower of a written demand for payment from Lender;

(b) Covenant Default. If Borrower violates any of the covenants contained in Article 7 of this Agreement, or fails or neglects to perform, keep, or observe any other material term, provision, condition, covenant, or agreement contained in this Agreement, in any of the Loan Documents and has failed to cure such default within 30 days after Borrower receives notice thereof or any officer of Borrower becomes aware thereof; provided, however, that if the default cannot by its nature be cured within such 30-day period or cannot after diligent attempts by Borrower be cured within such 30-day period, and such default is likely to be cured within a reasonable time, then Borrower shall have an additional reasonable period (which shall not in any case exceed 30 days) to attempt to cure such default, and within such reasonable time period the failure to have cured such default shall not be deemed a Borrower Event of Default (provided that no Advance will be required to be made during such cure period);

(c) Attachment. If any material portion of Borrower’s assets is attached, seized, subjected to a writ or distress warrant, or is levied upon, or comes into the possession of any trustee, receiver or person acting in a similar capacity and such attachment, seizure, writ or distress warrant or levy has not been removed, discharged or rescinded within 30 days, or if Borrower is enjoined, restrained, or in any way prevented by court order from continuing to conduct all or any material part of its business affairs, or if a judgment or other claim becomes a lien or encumbrance upon any material portion of Borrower’s assets, or if a notice of lien, levy, or assessment is filed of record with respect to any of Borrower’s assets by the United States government, or any department, agency, or instrumentality thereof, or by any state, county, municipal, or governmental agency, and the same is not paid within 30 days after Borrower

receives notice thereof; provided that none of the foregoing shall constitute a Borrower Event of Default where such action or event is stayed or an adequate bond has been posted pending a good faith contest by Borrower (provided that no Advance will be required to be made during such cure period);

(d) Insolvency. If an Insolvency Proceeding is commenced by Borrower, or if an Insolvency Proceeding is commenced against Borrower and is not dismissed or stayed within 30 days (provided that no Advance will be made prior to the dismissal of such Insolvency Proceeding);

(e) Judgments. If a judgment or judgments for the payment of money in an amount, individually or in the aggregate, of at least $50,000 shall be rendered against Borrower and shall remain unsatisfied and unstayed for a period of 30 days (provided that no Advance will be made prior to the satisfaction or stay of such judgment); or

(f) Misrepresentations. If any material misrepresentation, misstatement or omission exists now or hereafter in any warranty or representation set forth herein or in any certificate delivered to Lender by any Responsible Officer pursuant to this Agreement or to induce Lender to enter into this Agreement or any other Loan Document.

(a) Rights and Remedies. Upon the occurrence and during the continuance of a Borrower Event of Default, Lender may, at its election, without notice of its election and without demand, do any one or more of the following, all of which are authorized by Borrower:

(i) Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and payable (provided that upon the occurrence of a Borrower Event of Default described in Section 8.4 all Obligations shall become immediately due and payable without any action by Lender);

(ii) Cease advancing money or extending credit to or for the benefit of Borrower under this Agreement or under any other agreement between Borrower or Lender;

(iii) Without notice to or demand upon Borrower, make such payments and do such acts as Lender considers necessary or reasonable to protect its security interest in the Collateral. Borrower agrees to assemble the Collateral if Lender so requires, and to make the Collateral available to Lender as Lender may designate. Borrower authorizes Lender to enter the premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any encumbrance, charge, or lien that in Lender’s determination appears to be prior or superior to its security interest and to pay expenses incurred in connection therewith. With respect to any of Borrower’s owned premises, Borrower hereby grants Lender a license to enter into possession of such premises and to occupy the same, without charge in order to exercise any of Lender’s rights or remedies provided herein, at law, in equity, or otherwise;

(iv) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Collateral. Lender is hereby granted a license or other right, solely pursuant to the provisions of this Section 9.1, to use, without charge, Borrower’s labels, Patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any property of a similar nature, as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Lender’s exercise of its rights under this Section 9.1, Borrower’s rights under all licenses and all franchise agreements shall inure to Lender’s benefit;

(v) Sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Borrower’s premises) as Lender determines is commercially reasonable, and apply any proceeds to the Obligations in whatever manner or order Lender deems appropriate;

(vii) Any deficiency that exists after disposition of the Collateral as provided will be paid immediately by Borrower.

(b) Power of Attorney. Effective only upon the occurrence and during the continuance of an Borrower Event of Default, Borrower hereby irrevocably appoints Lender (and any of Lender’s designated officers or employees) as Borrower’s true and lawful attorney to: (i) send requests for verification of Accounts or notify account debtors of Lender’s security interest in the Accounts; (ii) endorse Borrower’s name on any checks or other forms of payment or security that may come into Lender’s possession; (iii) sign Borrower’s name on any invoice or bill of lading relating to any Account, drafts against account debtors, schedules and assignments of Accounts, verifications of Accounts, and notices to account debtors; (iv) make, settle, and adjust all claims under and decisions with respect to Borrower’s policies of insurance; (v) file, in its sole discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral without the signature of Borrower where permitted by law; (vi) transfer any Collateral into the name of Lender or a third party to the extent permitted under the UCC; provided that Lender may exercise such power of attorney to sign the name of Borrower on any of the documents described in Section 4.2 regardless of whether a Borrower Event of Default has occurred; and (vii) settle and adjust disputes and claims respecting the accounts directly with account debtors, for amounts and upon terms that Lender determines to be reasonable; provided that Lender may exercise such power of attorney to sign the name of Borrower on any of the documents described in Section 4.2 regardless of whether a Borrower Event of Default has occurred. The appointment of Lender as Borrower’s attorney in fact, and each and every one of Lender’s rights and powers, being coupled with an interest, is irrevocable until all of the Obligations have been fully repaid and performed and Lender’s obligation to provide Advances hereunder is terminated.

(c) Accounts Collection. At any time from the date of this Agreement, Lender may notify any Person owing funds to Borrower of Lender’s security interest in such funds and verify the amount of such Account. After the occurrence and during the continuance of

a Borrower Event of Default, Borrower shall collect all amounts owing to Borrower for Lender, receive in trust all payments as Lender’s trustee, and immediately deliver such payments to Lender in their original form as received from the account debtor, with proper endorsements for deposit.

(d) License. Lender shall have a nonexclusive, royalty-free license to use the Intellectual Property to the extent reasonably necessary to permit Lender to exercise its rights and remedies upon the occurrence of a Borrower Event of Default.

(e) Lender’s Liability for Collateral. So long as Lender complies with Section 9.207 of the UCC, Lender shall not in any way or manner be liable or responsible for: (i) the safekeeping of the Collateral; (ii) any loss or damage thereto occurring or arising in any manner or fashion from any cause; (iii) any diminution in the value thereof; or (iv) any act or default of any carrier, warehouseman, bailee, forwarding agency, or other Person whomsoever. All risk of loss, damage or destruction of the Collateral shall be borne by Borrower.

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

(g) Demand; Protest. Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees at any time held by Lender on which Borrower may in any way be liable.

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 that 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 Borrower or to Lender, as the case may be, at its address set forth below:

The parties may change the address at which they are to receive notices hereunder, by notice in writing in the foregoing manner given to the other.

This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of Texas, without regard to principles of conflicts of laws. Each of Borrower and Lender hereby submits to the exclusive jurisdiction of the state and federal courts located in Travis County, Texas. BORROWER AND LENDER EACH HEREBY WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS. EACH PARTY RECOGNIZES AND AGREES THAT THE FOREGOING WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR IT TO ENTER INTO THIS AGREEMENT. EACH PARTY REPRESENTS AND WARRANTS THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL.

(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 Borrower without Lender’s prior written consent, which consent may be granted or withheld in Lender’s sole discretion. Except in connection with a sale of Lender (through a merger, consolidation, sale of all of its assets or stock, or similar transaction), Lender shall not have the right without the consent of Borrower to sell, transfer, negotiate, or grant participation in all or any part of, or any interest in, Lender’s obligations, rights and benefits hereunder.

(b) Indemnification. Borrower shall defend, indemnify and hold harmless Lender and its officers, employees, and agents against: (i) all obligations, demands, claims, and liabilities claimed or asserted by any other party in connection with the transactions contemplated by this Agreement; and (ii) all losses or Lender Expenses in any way suffered, incurred, or paid by Lender as a result of or in any way arising out of, following, or consequential to transactions between Lender and Borrower whether under this Agreement, or otherwise (including without limitation reasonable attorney’s fees and expenses), except for losses caused by Lender’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 other 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. Signatures transmitted via facsimile shall be deemed originals for purposes of this Agreement.

(g) Survival. All covenants, representations and warranties made in this Agreement shall continue in full force and effect so long as any Obligations remain outstanding. The obligations of Borrower to indemnify Lender with respect to the expenses, damages, losses, costs and liabilities described in Section 12.2 shall survive until all applicable statute of limitations periods with respect to actions that may be brought against Lender have run.

(h) Usury. All agreements between Borrower and Lender, whether now existing or hereafter arising and whether written or oral, are expressly limited so that in no contingency or event whatsoever, whether by acceleration of the maturity of the Note or otherwise, shall the amount paid, or agreed to be paid, to Lender for the use, forbearance or detention of the money to be loaned hereunder or otherwise, exceed the maximum amount permissible under applicable law. If from any circumstances whatsoever fulfillment of any provision of this Agreement or the other Loan Documents or of any other document evidencing, securing or pertaining to the indebtedness evidenced hereby, at the time performance of such provision shall be due, shall involve transcending the limit of validity prescribed by law, then ipso facto, the obligation to be fulfilled shall be reduced to the limit of such validity, and if from any such circumstances Lender shall ever receive anything of value as interest or deemed interest by applicable law under this Agreement, any other Loan Document or any other document evidencing, securing or pertaining to the indebtedness evidenced hereby or otherwise an amount that would exceed the highest lawful rate, such amount that would be excessive interest shall be applied to the reduction of the principal amount owing under the Note or on account of any other indebtedness of Borrower to Lender relating to this Agreement, and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal of the Note and such other indebtedness, such excess shall be refunded to Borrower. In determining whether or not the interest paid or payable with respect to any indebtedness of Borrower to Lender, under any specific contingency, exceeds the highest lawful rate, Borrower and Lender shall, to the maximum extent permitted by applicable law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) amortize, prorate, allocate and spread the total amount of interest throughout the full term of such indebtedness so that the actual rate of interest

on account of such indebtedness is uniform throughout the term thereof and/or (iii) allocate interest between portions of such indebtedness, to the end that no such portion shall bear interest at a rate greater than that permitted by law. The terms and provisions of this section shall control and supersede every other conflicting provision of all agreements between Borrower and Lender.

(i) Termination of Prior Agreement. Borrower and Lender agree that the Prior Agreement is hereby amended and restated and shall be of no further force or effect.

(j) Joint Product. This Agreement and the other Loan Documents are the joint product of Borrower and Lender and each provision hereof and thereof has been subject to the mutual consultation, negotiation and agreement of Borrower and Lender and shall not be construed against either party.

Capitalized terms not defined herein shall have the meanings ascribed to such terms in that certain Acquisition Option Agreement dated as of December 16, 2003 (the “Option Agreement”).

WHEREAS, the Company, the Investor, the Stockholder and the holders of membership interests in the Stockholder are parties to the Option Agreement that provides for, among other things, the acquisition of the Company by the Investor;

WHEREAS, the Company and the Investor are entering into an Amended and Restated Loan and Security Agreement concurrently with the execution and delivery of this Agreement, whereby Investor would agree to provide additional financing to the Company, and, in connection with such transaction, desire to terminate the Option Agreement, amend certain other agreements to which the Company and the Investor are parties and provide for certain other rights as set forth herein;

WHEREAS, pursuant to Section 9.3 thereof, the Option Agreement may be terminated by the execution and delivery of a written agreement executed by the Company, the Investor and the Stockholder (unless the Stockholder has distributed the Common Stock of the Company held by the Stockholder to the holders of its membership interests);

WHEREAS, the Stockholder has not distributed the Common Stock of the Company held by the Stockholder; and

WHEREAS, the parties hereto desire to enter into this Agreement to provide for the termination of the Option Agreement and each Proxy entered into pursuant to the Option Agreement, and the amendment of certain other agreements.

NOW, THEREFORE, in consideration of the foregoing recitals and certain other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Termination of Option Agreement. Subject to the execution and delivery of the Amendments pursuant to Section 2 below, the Option Agreement and each Proxy delivered in favor of Investor pursuant thereto is hereby terminated pursuant to Section 9.3 of the Option Agreement and shall be of no further force and effect whatsoever; and each of the parties thereto is hereby deemed to have released any rights or claims of any kind (matured, contingent or otherwise) against each other party thereto arising out of the existence or operation of the

Option Agreement or the actions of the Company or the Investor under or in relation to such Option Agreement (but not any other agreement) during the period that the Option Agreement was in effect.

2. Amendments to Other Agreements. Concurrently with the effectiveness of the termination of the Option Agreement pursuant to Section 1 above, and as a material inducement for the other agreements contained herein, the applicable parties hereto are entering into amendments (the “Amendments”) to the Voting Agreement, Investor’s Rights Agreement and Right of First Refusal and Co-Sale Agreement, each dated as of December 16, 2003, the forms of which amendments are attached as Exhibits A, B and C, respectively.

(a) Notice. In the event that (A) the Company contemplates any liquidation, dissolution or winding up, either voluntary or involuntary or (B) has received a bona fide third party offer with respect to (i) the acquisition of the Company by another entity by means of any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation) unless the Company’s stockholders of record as constituted immediately prior to such acquisition will, immediately after such acquisition (by virtue of securities issued as consideration for the Company’s acquisition or otherwise) hold at least 50% of the voting power of the surviving or acquiring entity (except that the sale by the Company of shares of its capital stock to investors in bona fide common stock or preferred stock financing transactions shall not be deemed an acquisition for this purpose); (ii) the sale of a material portion of the assets of the Company, including the sale of a material portion of the assets of the Company’s subsidiaries, if such assets constitute a material portion of the assets of the Company and such subsidiaries taken as a whole; or (iii) the grant of an exclusive license of a material portion or all or substantially all of the Company’s intellectual property (each, a “Liquidation Transaction”), the Company shall give to the Investor a notice (a “Notice”) within one business day. Such Notice shall include a copy of any third party offer with respect to a Liquidation Transaction or if such offer is not is writing, then a summary of the material terms and conditions of the proposed Liquidation Transaction and the identity of the party making such proposal.

(b) Negotiation Period. The Investor shall have a period of 30 days following its receipt of the Notice (the “Negotiation Period”) in which to present to the Company a counter-offer or alternative proposal (an “Investor Offer”). During such 30 day period, the Investor, at its sole option, shall have the opportunity in such Investor Offer either to match such Liquidation Transaction proposal or to provide for consideration by the Company’s Board of Directors its own acquisition offer. In any event, during such 30 day period the Investor shall have the exclusive right to engage in negotiations with the Company with respect to such Investor Offer. During the Negotiation Period (the last date of which being the “Expiration Date”), the Company will not enter into an agreement, or otherwise accept an offer, with respect to, or effect, a Liquidation Transaction. If the Investor determines during the Negotiation Period it then has no interest in acquiring the Company or its technology, it will so notify the Company (a “Decline Notice”). If the Investor does not deliver an Investor Offer within the Negotiation Period, or if the Investor has issued a Decline Notice, then the Company shall be free, subject in any event to the other provisions of this Section 3, for a period of 90 days

following the expiration of the Negotiation Period, to agree to accept or effect the Liquidation Transaction proposal on the terms and conditions set forth in the Notice or on such other terms and conditions, in the aggregate, no more favorable to the potential acquiror than those specified in the Notice (such consummation or entry into a binding agreement, a “Binding Liquidation Transaction”). In the event of a Binding Liquidation Transaction during this 90-day period, the Investor will have no other rights under this section unless such Binding Liquidation Transaction is ultimately abandoned without being consummated. In the event that no Binding Liquidation Transaction is consummated during such 90-day period, then the provisions of this section shall again apply. Any proposed acquisition of the Company or sale or liquidation of its assets pursuant to an Liquidation Transaction proposal after the end of such 90-day period or any change in the terms of such Liquidation Transaction proposal which are more favorable to the potential acquiror shall require a new Notice, and shall give rise anew to the rights of the Investor provided in this Section 3.

(a) Amendment and Waiver. Any term or provision of this Agreement may be amended only by the written consent of the Company and the Investor. The observance of any term of this Agreement may be waived (either generally or in a particular instance and

either retroactively or prospectively) only by a writing signed by the party to be bound by such waiver.

(b) Governing Law. The construction, validity and interpretation of this Agreement will be governed by the internal laws of the State of Delaware without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

THIS PROMISSORY NOTE IS SECURED BY CERTAIN ASSETS OF BORROWER. THE TERMS OF SUCH SECURITY INTEREST AND ADDITIONAL TERMS REGARDING THIS PROMISSORY NOTE ARE SET FORTH IN, AND CERTAIN TERMS OF THIS NOTE ARE SUBJECT TO, A LOAN AND SECURITY AGREEMENT BETWEEN BORROWER AND THE HOLDER.

NexQL Corporation, a Delaware corporation (“Borrower”), for value received, promises to pay to the order of Crossroads Systems, Inc. (together with its successors and permitted assigns, “Holder”), the principal amount(s) advanced as a loan or loans to Borrower in an aggregate principal amount payable to Holder of up to Two Million Dollars ($2,000,000) or such lesser amount outstanding, together with (i) interest in arrears from and including the date hereof on the unpaid principal balance of such amount(s) or any portion thereof advanced to Borrower pursuant to that certain Amended and Restated Loan and Security Agreement dated as of March 22, 2005 (the “Loan Agreement”) and Section 3 of this Secured Convertible Promissory Note (this “Note”) from the date such advances are made at a rate of 6.0% per annum (except as otherwise provided in Section 5 below), and (ii) any and all other amounts due under this Note. Capitalized terms used but not defined herein shall have the meanings ascribed to such terms in the Loan Agreement.

1. Maturity Date. This Note shall be due and payable on the earliest to occur of (if not earlier converted pursuant to Section 4 below):

Proceedings against Borrower) until March 15, 2007; provided, however, that such forbearance shall only be effective for so long as: (A) Borrower is actively seeking alternate purchasers of shares of its capital stock to consummate a Qualified Financing; (B) no other Insolvency Proceeding has been initiated by or against Borrower; (C) no Liquidation Event (as defined below in clause (ii) of this definition) has occurred nor has Borrower agreed to or become bound with respect to a Liquidation Event, whether by definitive agreement or letter of intent, orally or in writing; and (D) no Borrower Event of Default has occurred (other than a “Payment Default” under Section 9(a) of the Loan Agreement).

For purposes of this Note, a “Qualified Financing” means the next equity financing of Borrower after the date hereof in which Borrower sells shares of its capital stock resulting in gross proceeds to Borrower (including any amounts converted pursuant to the terms of this Note) of at least $5,000,000, excluding proceeds received upon the exercise of stock options issued to employees or service providers of Borrower.

2. Security. The obligations due under this Note are secured by all of the assets of Borrower pursuant to the Loan Agreement. Additional rights of Holder are set forth in the Loan Agreement.

3. Borrowing Procedure. Amounts under this Note will be made available by Holder as soon as reasonably practicable following Holder’s receipt of a properly completed Request for Advance in substantially the form attached hereto as Exhibit A (the “Request for Advance”). Such Request for Advance shall be irrevocable and binding on Borrower. Upon fulfillment of these conditions set forth in the Request for Advance and the Loan Agreement, Holder shall make the Advances available to Borrower in same-day funds, or such other funds as shall separately be agreed upon by Borrower and Holder, in accordance with the payment instructions provided to Holder in the Request for Advance.

Holder shall record the date and amount of each advance, the amount of principal and interest due and payable from time to time hereunder, each payment thereof and the resulting unpaid principal balance hereof, on the schedule annexed to this Note, to which Holder may add additional pages. Each such record of any advance under this Note shall be conclusive evidence that the advance was made to Borrower; provided that the failure to make any such record shall not in any way affect Borrower’s obligations under this Note.

(a) Automatic Conversion. In the event Borrower consummates a Qualified Financing on or before the Maturity Date, all principal and accrued unpaid interest of this Note shall automatically be converted, in whole but not in part, upon the closing of such Qualified Financing into the shares of capital stock of Borrower sold in the Qualified Financing (the “Qualified Financing Securities”), at the weighted average price per share paid in the Qualified Financing..

(b) Optional Conversion. At any time on or prior to the Maturity Date, in the event Borrower consummates an equity financing that is not a Qualified Financing (a “Next Equity Financing”), Holder may, at its option, convert the then-outstanding principal amount of this Note, together with any accrued but unpaid interest thereon into that number of shares of securities of Borrower sold in such Next Equity Financing (the “Next Equity Financing Securities”) equal to the aggregate amount of principal and accrued but unpaid interest then outstanding under this Note, divided by the weighted average price per share at which Next Equity Financing Securities were sold in the Next Equity Financing.

(i) Automatic Conversion. Upon the automatic conversion of this Note, Borrower shall give written notice to Holder, notifying Holder of such conversion and specifying the lowest price per share at which the Qualified Financing Securities were sold in the Qualified Financing, the principal amount of the Note converted and the date on which such conversion occurred and calling upon Holder to surrender the Note to Borrower. Upon such conversion, Holder shall surrender this Note at Borrower’s principal executive office, or, if this Note has been lost, stolen, destroyed or mutilated, then, in the case of loss, theft or destruction, Holder shall deliver an indemnity agreement reasonably satisfactory in form and substance to Borrower or, in the case of mutilation, Holder shall surrender and cancel this Note. Borrower shall, as soon as practicable thereafter, issue and deliver to Holder at such principal executive office a certificate or certificates for the number of shares to which Holder shall be entitled upon such conversion (bearing such legends as are required by applicable state and federal securities laws in the opinion of counsel to Borrower and any other agreements to which Holder is a party). Such conversion shall be deemed to have been made simultaneously with the initial closing of the Qualified Financing, and thereafter Holder shall be treated for all purposes as the record holder of such shares.

(ii) Voluntary Conversion. If Holder elects to convert this Note into Common Stock, Holder shall notify Borrower in writing of such election. Upon the

delivery of such notice to Borrower, this Note shall convert into Common Stock as provided in subsection (b) above. In connection with such conversion, Holder shall surrender this Note at Borrower’s principal executive office, or, if this Note has been lost, stolen, destroyed or mutilated, then, in the case of loss, theft or destruction, Borrower shall deliver an indemnity agreement reasonably satisfactory in form and substance to Borrower or, in the case of mutilation, Holder shall surrender and cancel this Note. Borrower shall, as soon as practicable thereafter, issue and deliver to Holder at such principal executive office a certificate or certificates for the number of shares to which Holder shall be entitled upon such conversion (bearing such legends as are required by applicable state and federal securities laws in the opinion of counsel to Borrower and any other agreements to which Holder is a party). Thereafter, Holder shall be treated for all purposes as the record holder of such shares of Common Stock.

(d) Fractional Shares; Nonassessable; Effect of Conversion. Any fractional shares to be issued upon conversion of this Note shall be rounded down to the nearest whole share. Borrower covenants that the shares of Qualified Financing Securities or Common Stock, as the case my be, issuable upon the conversion of this Note will, upon conversion of this Note, be validly issued, fully paid and nonassessable and free from all taxes, liens and charges in respect of the issue thereof. Upon proper conversion of this Note in full, Borrower shall be forever released from all its obligations and liabilities under this Note.

(a) Payments. Borrower will make all payments due under this Note in immediately available funds by 11:00 a.m. (Austin, Texas time) on the date such payment is due in a manner that Holder or other registered holder of this Note may from time to time direct. All payments hereunder shall be payable in lawful money of the United States of America that is legal tender for public and private debts at the time of payments.

(b) Interest Rate Adjustment. Until the earlier to occur of the Maturity Date or an Event of Default, Borrower shall not be required to make payments of principal or interest. Thereafter, Borrower shall repay in full all principal and unpaid interest then outstanding under this Note (interest being computed on the basis of a 360-day year and actual days elapsed) at a rate of 6% per annum; provided, however, in the event of any Liquidation Event (not involving Holder), the rate of interest on this Note shall be the lesser of 12% per annum or the highest lawful rate of interest and shall be deemed to have accrued on all outstanding indebtedness under this Note as of the date of such Liquidation Event.

(c) Prepayment. This Note may not be prepaid by Borrower in whole or in part without the prior written consent of Holder. Any permitted prepayment will be made in lawful tender of the United States and will be applied (a) first, to the payment of accrued interest and (b) second, (to the extent that the amount of such payment exceeds the amount of all such accrued interest), to the payment of principal.

6. Default. Borrower will be deemed to be in default under this Note at any time there exists, and for such time as there continues, a Borrower Event of Default pursuant to the Loan Agreement.

7. Governing Law. THIS AGREEMENT SHALL BE GOVERNED IN ALL RESPECTS BY THE LAWS OF THE STATE OF TEXAS AS SUCH LAWS ARE APPLIED TO AGREEMENTS BETWEEN TEXAS RESIDENTS ENTERED INTO AND TO BE PERFORMED ENTIRELY WITHIN TEXAS WITHOUT REGARD TO THE CONFLICTS OF LAWS PRINCIPLES THEREOF.

The Board shall promptly respond in writing to an inquiry by the Holder as to the fair market value of any securities the Holder may wish to deliver to the Company pursuant to clause (iii) above.

4. Net Issue Election. In lieu of exercise pursuant to Section 3, the Holder may elect to receive, without the payment by the Holder of any additional consideration, shares equal to the value of this Warrant or any portion hereof by the surrender of this Warrant or such portion to the Company, with the net issue election notice annexed hereto duly executed, at the office of the Company. Thereupon, the Company shall issue to the Holder such number of fully paid and nonassessable Warrant Shares as is computed using the following formula:

Y = the number of shares covered by this Warrant in respect of which the net issue election is made pursuant to this Section 4.

A = the fair market value of one Warrant Share, as determined in good faith by the Board, as at the time the net issue election is made pursuant to this Section 4.

B = the Exercise Price in effect under this Warrant at the time the net issue election is made pursuant to this Section 4.

The Company shall promptly respond in writing to an inquiry by the Holder as to the fair market value of one Warrant Share.

5. Partial Exercise. This Warrant may be exercised in part, and the Holder shall be entitled to receive a new warrant, which shall be dated as of the date of this Warrant, covering the number of shares in respect of which this Warrant shall not have been exercised.

6. Issuance Date. The person or persons in whose name or names any certificate representing any Warrant Shares issued hereunder shall be deemed to have become the holder of record of the shares represented thereby as at the close of business on the date this Warrant is exercised with respect to such shares, whether or not the transfer books of the Company shall be closed.

7. Expiration Date. This Warrant shall expire on the earlier to occur of: (i) the close of business on March 22, 2015; and (ii) the occurrence of a “Change of Control” in which the Holder acquires the Company by means of (A) any transaction or series of related transactions (including, without limitation, any reorganization, merger or consolidation) unless the Company’s stockholders of record as constituted immediately prior to such acquisition will, immediately after such acquisition (by virtue of securities issued as consideration for the Company’s acquisition or otherwise) hold at least 50% of the voting power of the surviving or acquiring entity (except that the sale by the Company of shares of its capital stock to the Holder and/or other investors in common stock or preferred stock financing transactions shall not be deemed an acquisition for this purpose); or (B) the sale (i.e., the purchase by the Holder) of all or substantially all of the assets of the Company, including the sale (i.e., the purchase by the Holder) of all or substantially all of the assets of the Company’s subsidiaries, if such assets constitute substantially all of the assets of the Company and such subsidiaries taken as a whole.

8. Reserved Shares; Valid Issuance. The Company covenants and agrees that all Warrant Shares that may be issued upon exercise hereof (and upon any conversion of Warrant Shares) will, upon issuance, be duly and validly issued, fully paid and non-assessable and no personal liability will attach to the holder thereof. The Company further covenants and agrees that, during the period within which this Warrant may be exercised, the Company will at all times have authorized and reserved a sufficient number of shares of capital stock as appropriate for issuance upon exercise of this Warrant (and the conversion of the Warrant Shares, if appropriate).

9. Stock Dividends. If after the Original Issue Date the Company shall subdivide its capital stock underlying this Warrant Stock, by split-up or otherwise, or combine such capital stock, or issue additional shares of such capital stock in payment of a stock dividend on such capital stock, the number of shares issuable on the exercise of this Warrant shall forthwith be proportionately increased in the case of a subdivision or stock dividend, or proportionately decreased in the case of a combination, and the Exercise Price shall forthwith be proportionately decreased in the case of a subdivision or stock dividend, or proportionately increased in the case of a combination.

10. Mergers and Reclassifications. If after the original issue date of this Warrant there shall be any reclassification, capital reorganization or change of the Warrant Shares (other than as a result of a subdivision, combination or stock dividend provided for in Section 9 hereof), or any consolidation of the Company with, or merger of the Company into, another corporation or other business organization (other than a consolidation or merger in which the Company is the

continuing corporation and which does not result in any reclassification or change of the outstanding capital stock underlying this Warrant), or any sale or conveyance to another corporation or other business organization of all or substantially all of the assets of the Company, then, as a condition of such reclassification, reorganization, change, consolidation, merger, sale or conveyance, lawful provisions shall be made, and duly executed documents evidencing the same from the Company or its successor shall be delivered to the Holder, so that the Holder shall thereafter have the right to purchase, at a total price not to exceed that payable upon the exercise of this Warrant in full, the kind and amount of shares of stock and other securities and property receivable upon such reclassification, reorganization, change, consolidation, merger, sale or conveyance by a holder of the number of Warrant Shares that might have been purchased by the Holder immediately prior to such reclassification, reorganization, change, consolidation, merger, sale or conveyance, and in any such case appropriate provisions shall be made with respect to the rights and interest of the Holder to the end that the provisions hereof (including without limitation, provisions for the adjustment of the Exercise Price and the number of shares issuable hereunder) shall thereafter be applicable in relation to any shares of stock or other securities and property thereafter deliverable upon exercise hereof.

11. Fractional Shares. In no event shall any fractional shares of capital stock of the Company be issued upon any exercise of this Warrant. If, upon exercise of this Warrant as an entirety, the Holder would, except as provided in this Section 11, be entitled to receive a fractional share of capital stock of the Company, then the Company shall issue the next higher number of full shares of capital stock, issuing a full share with respect to such fractional share.

12. Certificate of Adjustment. Whenever the Exercise Price (including the adjustments to the Conversion Price pursuant to Section 2(b) hereof) is adjusted, as herein provided, the Company shall promptly deliver to the Holder a certificate setting forth the Exercise Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

(a) any taking by the Company of a record of the holders of any class of securities for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, or any right to subscribe for, purchase or otherwise acquire any shares of stock of any class or any other securities or property, or to receive any other right,

(b) any reclassification of the capital stock of the Company, capital reorganization of the Company, consolidation or merger involving the Company, or sale or conveyance of all or substantially all of its assets, or

then and in each such event the Company will mail or cause to be mailed to the Holder a notice specifying (i) the date on which any such record is to be taken for the purpose of such dividend, distribution or right, and stating the amount and character of such dividend, distribution or right, or (ii) the date on which any such reclassification, reorganization, consolidation, merger, sale or conveyance, dissolution, liquidation or winding-up is to take place, and the time, if any is to be

fixed, as of which the holders of record in respect of such event are to be determined. Such notice shall be mailed at least 20 days prior to the date specified in such notice on which any such action is to be taken.

15. Amendment. The terms of this Warrant may be amended, modified or waived only with the written consent of the Company and the Holder.

(a) The Company will maintain a register containing the name and address of the Holders. The Holder may change its address as shown on the warrant register by written notice to the Company requesting such change. Any notice or written communication required or permitted to be given to the Holder may be given by certified mail or delivered to the Holder at its address as shown on the warrant register.

(b) Subject to compliance with applicable federal and state securities laws, this Warrant may be transferred by the Holder with respect to any or all of the shares purchasable hereunder. Upon surrender of this Warrant to the Company, together with the assignment hereof properly endorsed, for transfer of this Warrant as an entirety by the Holder, the Company shall issue a new warrant of the same denomination to the assignee. Upon surrender of this Warrant to the Company, together with the assignment hereof properly endorsed, by the Holder for transfer with respect to a portion of the shares of capital stock of the Company purchasable hereunder, the Company shall issue a new warrant to the assignee, in such denomination as shall be requested by the Holder hereof, and shall issue to such Holder a new warrant covering the number of shares in respect of which this Warrant shall not have been transferred.

(c) In case this Warrant shall be mutilated, lost, stolen or destroyed, the Company shall issue a new warrant of like tenor and denomination and deliver the same (i) in exchange and substitution for and upon surrender and cancellation of any mutilated Warrant, or (ii) in lieu of any Warrant lost, stolen or destroyed, upon receipt of evidence reasonably satisfactory to the Company of the loss, theft or destruction of such Warrant (including a reasonably detailed affidavit with respect to the circumstances of any loss, theft or destruction) and of indemnity reasonably satisfactory to the Company.

17. No Impairment. The Company will not, by amendment of its Certificate of Incorporation or through any reclassification, capital reorganization, consolidation, merger, sale or conveyance of assets, dissolution, liquidation, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of the Holder.

19. No Rights or Liability as a Stockholder. This Warrant does not entitle the Holder hereof to any voting rights or other rights as a stockholder of the Company. No provisions hereof, in the absence of affirmative action by the Holder hereof to purchase securities hereunder, and no enumeration herein of the rights or privileges of the Holder hereof shall give rise to any liability of such Holder as a stockholder of the Company.

20. Governing Law. The provisions and terms of this Warrant shall be governed by and construed in accordance with the internal laws of the State of Texas.

21. Successors and Assigns. This Warrant shall be binding upon the Company’s successors and assigns and shall inure to the benefit of the Holder’s successors, legal representatives and permitted assigns.
