AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER, executed this 1st day of November, 2011 (this “Agreement”), is by and among Presidio, Inc., a Georgia corporation (“Parent”), Indigo Merger Sub, Inc., a Delaware corporation and wholly owned Subsidiary of Parent (“Sub,” and together with Parent, the “Parent Parties”), and INX Inc., a Delaware corporation (“INX”).

RECITALS:

A. The respective boards of directors of Parent, Sub and INX have approved this Agreement and the INX Board of Directors deems it advisable and in the best interests of its stockholders to merge Sub with and into INX (the “Merger”) upon the terms and subject to the conditions set forth herein.

B. As a result of the Merger, and in accordance with the Delaware General Corporation Law, as amended (the “Delaware Law”), each issued and outstanding share (the “Common Shares”) of common stock, par value $0.01 per share, of INX shall be converted into the right to receive the Merger Consideration at the Effective Time.

C. Concurrently herewith, each of ▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇ and ▇▇▇▇ ▇▇▇▇ have entered into voting agreements with Parent (the “Voting Agreements”), pursuant to which such persons have agreed to vote all of their Common Shares in favor of the Merger, as set forth in greater detail therein.

AGREEMENT:

For and in consideration of the mutual promises contained herein, the benefits to be derived by each party hereunder and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Parent, Sub and INX agree as follows:

ARTICLE I

THE MERGER

Section 1.1 The Merger. Upon the terms and subject to the conditions set forth in Article VI, and in accordance with Delaware Law, at the Effective Time, Sub shall be merged with and into INX. As a result of the Merger, the separate corporate existence of Sub shall cease and INX shall continue as the surviving corporation of the Merger (the “Surviving Corporation”).

Section 1.2 Effective Time; Closing. As promptly as practicable (but no later than five Business Days) after the satisfaction or, if permissible, waiver in accordance with Section 7.5 of all of the conditions set forth in Article VI (other than conditions that by their nature can be satisfied only at the Closing but subject to the satisfaction or waiver of these conditions), the parties hereto shall cause the Merger to be consummated by duly filing a certificate of merger with the Secretary of State of the State of Delaware in substantially the form attached hereto as Exhibit 1.2, and in such form as is required by, and executed in accordance with, the relevant provisions of Delaware Law (the date and time of such filing being the “Effective Time”) and as mutually agreed to by INX and Parent. Prior to but on the same day as such filing, a closing (the “Closing”) shall be held at the offices of Weil, Gotshal & ▇▇▇▇▇▇ LLP, ▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇▇▇, or such other place as the parties shall agree, for the purpose of confirming the satisfaction or waiver, as the case may be, of the conditions set forth in Article VI. The date of the Closing is herein called the “Closing Date.”

Section 1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of the Delaware Law. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, powers and franchises of INX and Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of INX and Sub shall become the debts, liabilities and duties of the Surviving Corporation.

Section 1.4 Certificate of Incorporation; Bylaws. At the Effective Time, (i) the existing amended and restated certificate of incorporation of INX as in effect immediately prior to the Effective Time shall be amended and restated so as to read in its entirety as set forth in the form thereof attached hereto as Exhibit 1.4(a) and, as so amended, shall be the certificate of incorporation of the Surviving Corporation until duly amended in accordance with Applicable Law, and (ii) the existing amended and restated bylaws of INX shall be amended and restated so as to read in their entirety as set forth in the form thereof attached hereto as Exhibit 1.4(b) and, as so amended and restated, shall be the bylaws of the Surviving Corporation until duly amended in accordance with Applicable Law. As used in this Agreement, “Applicable Law” shall mean, in addition to the Delaware Law, any applicable domestic or foreign laws, common law, statutes, ordinances, rules, regulations, codes, orders or legally enforceable requirements enacted, issued, adopted, promulgated, enforced, ordered or applied by any Governmental Authority.

Section 1.5 Directors and Officers of Surviving Corporation. The parties hereto shall take, and cause to be taken, all actions necessary so that the directors and officers of Sub immediately prior to the Effective Time shall be the initial directors and officers, respectively, of the Surviving Corporation from the Effective Time until their respective successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal, in accordance with the certificate of incorporation and bylaws of the Surviving Corporation and Applicable Law.

Section 1.6 Conversion of Securities; Appraisal Rights. At the Effective Time, by virtue of the Merger and without any action on the part of Sub, INX or the holders of any of the Common Shares:

(a) Each share of Sub capital stock shall be converted into and become one fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation.

(b) Each Common Share issued and outstanding immediately prior to the Effective Time (other than any shares to be cancelled pursuant to Section 1.6(c) and other than Appraisal Shares) shall be converted automatically into the right to receive $8.75 in cash, without interest thereon (the “Merger Consideration”). As of the Effective Time, all Common Shares (whether represented by Certificates or held as Uncertificated Shares) shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of such Common Shares shall cease to have any rights with respect thereto, except, upon satisfaction of the conditions set forth in Section 1.8 of this Agreement, the right to receive the Merger Consideration, without interest.

(c) Each Common Share held in the treasury of INX and each Common Share, if any, owned by Sub, Parent or any direct or indirect wholly owned Subsidiary of Parent immediately prior to the Effective Time shall be cancelled without any conversion thereof, and no payment or distribution shall be made with respect thereto.

(d) Notwithstanding anything in this Agreement to the contrary, Common Shares that are outstanding immediately prior to the Effective Time and that are held by any Person who is entitled to demand, and properly demands, appraisal of such Common Shares (“Appraisal Shares”) pursuant to, and who complies in all respects with, Section 262 of the Delaware Law (“Section 262”) shall not be converted into the right to receive Merger Consideration as provided in Section 1.6(b), but rather the holders of Appraisal Shares shall be entitled to only such rights as are granted by Section 262; provided, however, that if any such holder shall fail to perfect or otherwise shall waive, withdraw or lose the right to appraisal under Section 262, then such Appraisal Shares shall be deemed to have been converted as of the Effective Time into, and to have become exchangeable solely for the right to receive, the Merger Consideration upon surrender of such Common Shares as provided in this Article I. INX shall provide prompt notice to Parent of any demands received by INX for appraisal of any Common Shares, any withdrawal of any such demand and any other demand, notice or instrument delivered to the INX prior to the Effective Time pursuant to the Delaware Law that relates to such demand, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. Prior to the Effective Time, INX shall not, without the prior written consent of Parent, make any payment with respect to, or settle or offer to settle, any such demands or agree to do any of the foregoing.

Section 1.7 Options and Restricted Shares.

(a) Section 1.7(a) of the INX Schedule sets forth a list indicating all outstanding Options under the Stock Plans. As soon as practicable following the date of this Agreement, the INX Board of Directors or, if appropriate, any committee thereof administering the Stock Plans, shall adopt such resolutions and/or take such other actions as may be required to provide that, at the Effective Time, (i) each Option listed on Section 1.7(a) of the INX Schedule shall be fully vested and exercisable and (ii) subject to the terms and conditions set forth below in this Section 1.7(a), each Option shall terminate and be cancelled at the Effective Time and each holder of an Option will be entitled to receive from Parent or the Surviving Corporation and shall receive as soon as practicable following the Effective Time (but in no event more than 30 days after the Effective Time) in full settlement and satisfaction of each such vested Option the applicable Option Cash Amount. The “Option Cash Amount” shall be equal to the net amount of the product of (i) the excess, if any, of the Merger Consideration over the exercise price per share of such Option, multiplied by (ii) the number of shares subject to such Option. If the exercise price per share of any Option equals or exceeds the Merger Consideration, the Option Cash Amount therefor shall be zero. Prior to the Effective Time, INX will provide notice, in a form reasonably acceptable to Parent, to all holders of Options informing them of such cancellation and Option Cash Amount. As used in this Agreement, “Options” means any option granted, and, immediately before the Effective Time not exercised, expired or terminated, to a current or former employee, director or independent contractor of INX or any former Subsidiary of INX or predecessor thereof to purchase Common Shares pursuant to the Stock Plans. As used in this Agreement, “Stock Plans” means the INX Inc. Incentive Plan (as amended and restated effective July 28, 2003, as amended) (the “2003 Incentive Plan”), the INX Inc. 2011 Incentive Plan (and together with the 2003 Incentive Plan, the “Incentive Plan”) and any other stock option, stock bonus, stock award, or stock purchase plan, program, agreement or arrangement of INX or any predecessor thereof or any other similar agreement entered into by INX.

(b) Section 1.7(b) of the INX Schedule sets forth a list indicating the Restricted Shares that will be fully vested at the Effective Time. As soon as practicable following the date of this Agreement, the INX Board of Directors or, if appropriate, any committee thereof administering the Stock Plans, shall adopt such resolutions or take such other actions as may be required to provide that, immediately prior to the Effective Time, each Restricted Share that is issued and outstanding immediately prior to the Effective Time shall vest in full. Any such Restricted Shares which become vested pursuant to this Section 1.7(b) shall be treated in the same manner as other Common Shares in connection with the Merger. As used in this Agreement, “Restricted Share” means any equity issued pursuant to a restricted stock award or a restricted stock unit award, entitling the recipient to receive, upon vesting, Common Shares no longer subject to a risk of forfeiture under any Stock Plan.

(c) As soon as practicable following the date of this Agreement, the INX Board of Directors or, if appropriate, any committee thereof administering the INX Inc. 2008 Employee Stock Purchase Plan (the “ESPP”) shall adopt such resolutions or take such other actions as may be required to provide that no new Offering Period or Purchase Period (as such terms are defined under the ESPP) shall commence following the date of this Agreement (including with respect to any suspended Offering Period or Purchase Period). Immediately prior to the Effective Time, all outstanding options under the ESPP shall automatically be exercised by applying all sums credited to participants accounts under the ESPP to the purchase of whole shares of Common Shares, in accordance with and subject to the provisions of the ESPP. Any such Common Shares received by participants in the ESPP shall be treated in the same manner as other Common Shares in connection with the Merger.

(d) Prior to the Effective Time, the INX Board of Directors shall adopt resolutions, in form and substance reasonably satisfactory to Sub, to terminate the Stock Plans and the ESPP as of the Effective Time.

Section 1.8 Surrender of Shares; Stock Transfer Books.

(a) Prior to the Effective Time, Parent shall designate a bank or trust company reasonably satisfactory to INX to act as agent (the “Exchange Agent”) for the holders of Common Shares in connection with the Merger to receive the Merger Consideration to which holders of Common Shares shall become entitled pursuant to Section 1.6. Prior to the Effective Time, Parent shall deposit with the Exchange Agent, in trust for the benefit of the holders of Common Shares, for payment by the Exchange Agent in accordance with this Article I, the cash necessary to pay to the holders of the Common Shares converted into the right to receive Merger Consideration (the “Exchange Fund”). The Exchange Agent, pursuant to irrevocable instructions consistent with the terms of this Agreement, shall deliver such cash to be paid pursuant to Section 1.6 out of the Exchange Fund, and the Exchange Fund shall not be used for any other purpose whatsoever. The Exchange Fund shall be invested by the Exchange Agent as directed by the Surviving Corporation; provided, however, that such investments shall be in obligations of or guaranteed by the United States of America or of any agency thereof and backed by the full faith and credit of the United States of America, in commercial paper obligations rated A-1 or P-1 or better by ▇▇▇▇▇’▇ Investors Services, Inc. or Standard & Poor’s Corporation, respectively, or in deposit accounts, certificates of deposit or banker’s acceptances of, repurchase or reverse repurchase agreements with commercial banks with capital, surplus and undivided profits aggregating in excess of $500 million (based on the most recent financial statements of such bank which are then publicly available at the Securities and Exchange Commission (“SEC”) or otherwise); provided, further, that no loss on any investment made pursuant to this Section 1.8 shall affect the Merger Consideration payable to the holders of Common Shares and, following any losses, Parent shall promptly provide additional funds to the Exchange Agent for the benefit of the stockholders of INX in the amount of any such losses.

(b) Promptly after the Effective Time and in any event not later than the fifth Business Day following the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate or certificates that immediately prior to the Effective Time represented outstanding Common Shares (the “Certificates”), and to each holder of record of uncertificated Common Shares (the “Uncertificated Shares”), in each case whose shares were converted into the right to receive the Merger Consideration pursuant to Section 1.6, (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates or the Uncertificated Shares shall pass, only upon delivery of the Certificates or the transfer of the Uncertificated Shares to the Exchange Agent and shall be in such form and have such other provisions as Parent may reasonably specify) in a form reasonably acceptable to Parent and (ii) instructions for use in surrendering the Certificates or transfer of the Uncertificated Shares in exchange for the Merger Consideration. Each holder of Common Shares that have been converted into the right to receive the Merger Consideration shall be entitled to receive the Merger Consideration in respect of the Common Shares represented by a Certificate or Uncertificated Share upon (i) surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent or (ii) receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent may reasonably request) in the case of a book-entry transfer of Uncertificated Shares. Upon payment of the Merger Consideration pursuant to the provisions of this Article I, each Certificate or Uncertificated Share so surrendered or transferred shall forthwith be canceled. In the event of a transfer of ownership of Common Shares that is not registered in the transfer records of INX, payment may be made to a Person other than the Person in whose name the Certificate so surrendered or the Uncertificated Shares so transferred is registered if such Certificate shall be properly endorsed or otherwise be in proper form for transfer or such Uncertificated Shares shall be properly transferred and the Person requesting such issuance shall pay any transfer or other Taxes required by reason of the payment to a Person other than the registered holder of such Certificate or Uncertificated Shares or establish to the satisfaction of Parent that such Tax has been paid or is not applicable. Each Certificate and each Uncertificated Share (other than Certificates or Uncertificated Shares representing Appraisal Shares) shall be deemed at any time after the Effective Time to represent only the right to receive upon surrender in accordance with this Section 1.8 the Merger Consideration into which the Common Shares shall have been converted pursuant to Section 1.6. No interest shall be paid or shall accrue on any cash payable to holders of Certificates or Uncertificated Shares pursuant to the provisions of this Article I.

(c) The Merger Consideration paid upon the surrender for exchange of Certificates or transfer of Uncertificated Shares in accordance with the terms of this Article I shall be deemed to have been paid in full satisfaction of all rights pertaining to the Common Shares theretofore represented by such Certificates or Uncertificated Shares and there shall be no further registration of transfers on the stock transfer books of INX of the Common Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Uncertificated Shares are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article I, except as otherwise provided by Applicable Law.

(d) Any portion of the Exchange Fund that remains undistributed to the holders of Certificates or Uncertificated Shares for one year after the Effective Time shall be delivered to Parent, upon demand, and any holders of Certificates or Uncertificated Shares who have not theretofore complied with this Article I shall thereafter look only to Parent for payment of their claim for Merger Consideration.

(e) None of Parent, Sub, the Surviving Corporation, INX or the Exchange Agent shall be liable to any Person in respect of any cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate or Uncertificated Share shall not have been surrendered immediately prior to such date on which any amounts payable pursuant to this Article I would otherwise escheat to or become the property of any Governmental Authority, any such amounts shall, to the extent permitted by Applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

(f) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent, the posting by such Person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect thereto pursuant to this Agreement.

Section 1.9 Withholding Taxes. Notwithstanding anything in this Agreement to the contrary, Parent, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable to any former holder of Common Shares (and, for the avoidance of doubt, including Restricted Shares and/or Options) pursuant to this Agreement any amount as may be required to be deducted and withheld with respect to the making of such payment under applicable Tax laws. To the extent that amounts are so properly withheld by Parent, the Surviving Corporation or the Exchange Agent, as the case may be, and are paid over to the appropriate Governmental Authority in accordance with Applicable Law, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Common Shares in respect of which such deduction and withholding was made by Parent, the Surviving Corporation or the Exchange Agent, as the case may be.

Section 1.10 Taking of Necessary Action; Further Action. Each of Parent, Sub and INX shall use reasonable best efforts to take all such actions as may be necessary or appropriate in order to effectuate the Merger under Delaware Law as promptly as commercially practicable. If at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of INX, the officers and directors of the Surviving Corporation are fully authorized in the name of INX to take, and shall take, all such lawful and necessary action.

ARTICLE II

REPRESENTATIONS AND WARRANTIES OF INX

INX hereby represents and warrants to Parent and Sub that, except as otherwise set forth in reasonable detail (i) in INX’s Schedules to this Agreement delivered on the date hereof (the “INX Schedule”) (it being agreed by the parties that disclosure of any item in any section of the INX Schedule shall also be deemed to be disclosed with respect to any other section of this Agreement to which the relevance of such item is reasonably apparent) or (ii) in the INX SEC Reports filed between December 31, 2009 and the date of this Agreement (excluding any disclosure set forth therein under the heading “Risk Factors,” any disclosures in any section related to forward-looking statements to the extent that they are primarily predictive or cautionary in nature (other than factual information contained therein), or any statements in “Management’s Discussion and Analysis” or any exhibits to such filings):

Section 2.1 Organization and Qualification; Subsidiaries.

(a) INX is a corporation duly organized and validly existing in good standing under the laws of the State of Delaware.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF PARENT AND SUB

Parent and Sub hereby, jointly and severally, represent and warrant to INX that, except as otherwise set forth in the Parent Parties’ Schedule to this Agreement (the “Parent Schedule”) (it being agreed by the parties that disclosure of any item in any section of the Parent Schedule shall also be deemed to be disclosed with respect to any other section of this Agreement to which the relevance of such item is reasonably apparent):

(b) Sub is a direct, wholly owned Subsidiary of Parent that was formed solely for the purpose of engaging in the Transactions. Since the date of its incorporation and prior to the Effective Time, Sub has not carried, and will not carry, on any business or conduct any operations other than the execution of this Agreement, the performance of its obligations hereunder and matters ancillary thereto.

(a) Each of Parent and Sub has all requisite corporate power and authority to enter into this Agreement and to perform its obligations under this Agreement.

(b) The execution, delivery and performance of this Agreement by Parent and Sub and the consummation by Parent and Sub of the Transactions have been duly and validly authorized by all requisite corporate or other business entity action on the part of each of Parent and Sub (other than, with respect to the Merger, the filing of appropriate merger documents as required by Delaware Law).

(c) This Agreement has been duly executed and delivered by each of Parent and Sub and, assuming the due authorization, execution and delivery hereof by INX, constitutes a valid and binding obligation of each of Parent and Sub, enforceable against each of them in accordance with its terms, except as limited by bankruptcy, insolvency, moratorium, fraudulent transfer, reorganization and other laws of general applicability relating to or affecting the rights or remedies of creditors and by general equitable principles (whether considered in a proceeding in equity or at law).

(a) The execution and delivery of this Agreement by Parent or Sub does not, and the consummation by Parent or Sub of the Transactions will not, (i) violate the charter or bylaws or other comparable governing documents of Parent and Sub, (ii) constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under, any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which Parent or Sub or any of their Subsidiaries is a party or by which any of them or any of their respective properties are bound or (iii) result in the creation or imposition of any Lien upon any property of Parent, Sub or any of their Subsidiaries pursuant to the agreements and instruments referred to in clause (ii), except, in the case of clause (ii) or (iii), for such conflicts, breaches, violations, defaults or Liens, that have not had and are not reasonably likely to have, individually or in the aggregate, a Parent Material Adverse Effect. The term “Parent Material Adverse Effect” means a material adverse effect on the ability of either Parent or Sub to perform its obligations under this Agreement or to consummate the Merger or the Transactions.

(b) Except for (i) compliance with applicable requirements of the HSR Act and any other Applicable Law analogous to the HSR Act or otherwise regulating antitrust, competition or merger control matters in foreign jurisdictions, (ii) filing or recordation of merger or other appropriate documents as required by Delaware Law or Applicable Law of other states in which Parent or Sub is qualified to transact business, (iii) the filing of the Proxy Statement with the SEC in accordance with the Exchange Act and such reports under the Exchange Act as may be required in connection with this Agreement, the Merger and the Transactions and (iv) such other authorizations, consents, approvals or filings the failure of which to obtain or make have not had and are not reasonably likely to have, individually or in the aggregate, a Parent Material Adverse Effect, no authorization, consent or approval of or filing with any Governmental Authority is required to be obtained or made by Parent or Sub or any ultimate parent entity or controlling Person of Parent for the execution and delivery by either of them of this Agreement or the consummation by either of them of the Transactions.

Section 3.4 Proxy Statement. None of the information with respect to Parent or Sub that Parent or any of its Representatives furnishes in writing to INX expressly for use in the Proxy Statement, will, at the date such Proxy Statement is first delivered to the holders of the Common Shares or at the time of the INX Shareholders’ Meeting or at the time of any amendment or supplement thereof, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, no representation or warranty is made by Parent or Sub with respect to statements made or incorporated by reference therein supplied by INX or its Representatives expressly for inclusion or incorporation by reference in the Proxy Statement.

Section 3.5 Brokers; Transaction Fees. No broker, finder or investment banker is entitled to any advisory, brokerage, finder’s or other fee or commission in connection with the Transactions based upon arrangements made by or on behalf of Parent or Sub.

Section 3.6 Availability of Funds.

Section 3.7 Litigation. As of the date of this Agreement, there is no suit, action or proceeding by or before any Governmental Authority pending or, to the knowledge of Parent, threatened, against Parent or Sub challenging or seeking to prohibit the execution, delivery or performance of this Agreement or any of the Transactions.

Section 3.8 No Vote of Parent Stockholders. No vote of the stockholders of Parent or the holders of any other securities of Parent (equity or otherwise) is required by any Applicable Law, the certificate of incorporation or bylaws or other equivalent organizational documents of Parent, in order for Parent and Sub to consummate the Transactions.

Section 3.9 Solvency. Assuming (i) the accuracy as of the Effective Time in all material respects of the representations and warranties of INX set forth in Article II (ignoring all INX Material Adverse Effect and knowledge qualifiers) and (ii) any projections made available to Parent by INX have been prepared in good faith based upon reasonable assumptions, (A) the Surviving Corporation will not have incurred debts beyond its ability to pay such debts as they mature or become due and the then present fair salable value of the assets of the Surviving Corporation will exceed the amount that will be required to pay its respective probable liabilities (including the probable amount of all contingent liabilities) and its debts as they become absolute and matured, (B) the assets of the Surviving Corporation, in each case at a fair valuation, will exceed its debts (including the probable amount of all contingent liabilities) and (C) the Surviving Corporation will not have unreasonably small capital to carry on its business as presently conducted or as proposed to be conducted. No transfer of property is being made by Parent and Sub and no obligation is being incurred in connection with the Transactions by Parent and Sub with the intent to hinder, delay or defraud either present or future creditors of Parent, Sub or INX. For purposes of this Section 3.9, “debts beyond its ability to pay such debts as they mature or become due” and “unreasonably small capital to carry on its business as conducted or proposed to be conducted” means that the Surviving Corporation will not be able to generate enough cash from operations, asset dispositions or refinancing, or a combination thereof, to meet its obligations as they become due.

Section 3.10 Access. Parent acknowledges that it and its Representatives have received access to such books and records, facilities, equipment, contracts and other assets of INX which it and its Representatives have desired or requested to review, and that it and its Representatives have had full opportunity to meet with the senior management of INX and to discuss the business and assets of INX.

Section 3.11 Other Agreements or Understandings. Parent has disclosed to INX all agreements, arrangements or understandings (and, with respect to those that are written, Parent has furnished to INX correct and complete copies thereof) between or among Parent, Sub, or any affiliate of Parent, on the one hand, and any member of the INX Board of Directors or management of INX or any Person that, to Parent’s knowledge, owns 5% or more of the outstanding Common Shares, on the other hand.

Section 3.12 Ownership of Shares. Neither Parent nor Sub is, nor have either of them during the past three years been, the beneficial owner (as defined herein) of any Common Shares.

Section 3.13 Not Interested Shareholder. From the date that is three years prior to the date of this Agreement, neither Parent nor Sub, nor any of their respective “Affiliates” or “Associates” is or has been an “interested stockholder” (as such terms are defined in Section 203 of the Delaware Law) of INX for purposes of such Section 203.

The Parent Parties agree to indemnify and hold INX harmless from any and all claims and liabilities, including costs and expenses for loss, injury to or death of any Representative of the Parent Parties, and any loss, damage to or destruction of any property owned by INX or others (including claims or liabilities for loss of use of any property) resulting directly or indirectly from the action or inaction of any of the Parent Parties’ Representatives during any visit to the business or property sites of INX prior to the completion of the Merger, whether pursuant to this Section 5.2 or otherwise. Notwithstanding the foregoing, INX shall not be required to provide access to or otherwise disclose information if such information is subject to, or such access or disclosure would jeopardize, the attorney-client privilege, work product doctrine or other applicable privilege concerning legal proceedings or governmental investigations (provided that INX shall have used reasonable best efforts to disclose such information in a way that would not jeopardize such privilege) or which it is required to keep confidential by reason of contract or agreement with third parties (provided that INX shall have used reasonable best efforts to obtain the consent of such third party) or by reason of Applicable Law. None of the Parent Parties or any of their Representatives shall conduct any environmental testing or sampling on any of the business or property sites of INX prior to the completion of the Merger without the prior written consent of INX.

(b) Any information obtained by the Parent Parties or their Representatives under this Section 5.2 shall be subject to the confidentiality and use restrictions contained in that certain letter agreement between INX and Parent dated August 29, 2011 (the “Confidentiality Agreement”).

Section 5.3 No Solicitation.

(a) Notwithstanding any other provision of this Agreement to the contrary, during the period beginning on the date of this Agreement and continuing until 12:01 a.m. (New York City time) on November 22, 2011 (the “No-Shop Period Start Date”), INX and its Representatives shall have the right to, directly or indirectly, (i) initiate or solicit any inquiry, proposal or offer, in each case made after the date hereof, with respect to, or a transaction to effect, a merger, share exchange, consolidation, business combination, recapitalization or similar transaction involving INX, or any purchase or sale of 20% or more of the assets of INX, or any purchase or sale of, or tender or exchange offer for, its capital stock that, if consummated, would reasonably be expected to result in any Person (or the stockholders of such Person) beneficially owning securities representing 20% or more of INX’s total voting power (or of the surviving parent entity in such transaction) (any such inquiry, proposal, offer or transaction, an “Acquisition Proposal”), including by way of providing access to non-public information pursuant to one or more Acceptable Confidentiality Agreements; provided that INX agrees to provide Parent with all information provided to such Person that Parent has not previously been provided promptly following the date on which INX provides such confidential information to such Person, (ii) engage in, enter into, continue or otherwise participate in any discussion or negotiations with any Person concerning an Acquisition Proposal or grant any waiver, amendment or release under any confidentiality restriction in any agreement or under Applicable Law. Notwithstanding the occurrence of the No-Shop Period Start Date, INX and its Representatives may continue to provide access to non-public information and engage in the activities described in clause (ii) above with respect to each Excluded Party until 11:59 p.m. (New York City time) on December 1, 2011 (the “Cut-off Date”). “Acceptable Confidentiality Agreement” means any customary confidentiality agreement that contains provisions that are no less favorable in the aggregate to INX than those contained in the Confidentiality Agreement, except that an Acceptable Confidentiality Agreement need not prohibit the submission of Acquisition Proposals or amendments thereto. “Excluded Party” means any Person from whom INX has received, after the date hereof and prior to the No-Shop Period Start Date, a written Acquisition Proposal that the INX Board of Directors concludes in good faith after consultation with its outside legal counsel and financial advisors constitutes or is reasonably likely to lead the a Superior Proposal. No later than two Business Days after the No-Shop Period Start Date, INX shall provide to Parent in writing a complete list of all Excluded Parties (including the identity of each Excluded Party) and shall provide to Parent (i) an unredacted copy of any Acquisition Proposal made in writing provided to INX (including any financing commitments relating thereto, which shall include any fee letters (it being understood that any such fee letter may be redacted to omit the numerical amounts provided therein)) and (ii) a written summary of the material terms of any Acquisition Proposal not made in writing (including any financing commitments and any fee letters relating thereto (it being understood that any such fee letter may be redacted to omit the numerical amounts provided therein)).

(b) Except as may relate to any Excluded Party until the Cut-off Date or as permitted by this Section 5.3, INX shall not, and shall cause its Representatives not to, (i) initiate or solicit any inquiry, proposal or offer, in each case made after the date hereof, with respect to, or a transaction to effect, an Acquisition Proposal, (ii) have any discussion with or provide any confidential information to any Person relating to an Acquisition Proposal, or engage in any negotiations concerning an Acquisition Proposal or grant any waiver, amendment or release under any confidentiality restriction in any agreement or under Applicable Law, (iii) approve or recommend any Acquisition Proposal or (iv) approve or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, acquisition agreement or other similar agreement or agree to do any of the foregoing related to any Acquisition Proposal.

(c) Notwithstanding anything in this Agreement to the contrary, during the period beginning on the No-Shop Period Start Date and ending on the date the INX Shareholder Approval is obtained, INX or the INX Board of Directors may engage or participate in negotiations or discussions with, or provide any information to, any Person in response to an Acquisition Proposal that did not result from or arise in connection with a breach of Section 5.3(b) if (A) the INX Board of Directors concludes in good faith after consultation with its financial advisors and outside legal counsel that such Acquisition Proposal constitutes or is reasonably likely to lead to a Superior Proposal and (B) prior to providing any confidential information to any Person in connection with an Acquisition Proposal by any such Person, INX receives from such Person an Acceptable Confidentiality Agreement, provided that INX agrees to provide reasonably prompt notice to Parent of the identity of the Person that it is furnishing information to, or entering into discussions or negotiations with, and to provide Parent with all information provided to such Person that Parent has not previously been provided promptly following the date on which INX provides such confidential information to such Person. Notwithstanding anything in this Agreement to the contrary, during the period beginning on the date hereof and ending at the time that the INX Shareholder Approval is obtained, INX or the INX Board of Directors may withdraw, modify, qualify or fail to make (or publicly propose to withdraw, modify or qualify) the INX Recommendation and/or approve or recommend (or publicly propose to approve or recommend) any Acquisition Proposal or letter of intent, agreement in principle, acquisition agreement or similar agreement providing for any Acquisition Proposal (a “Change in the INX Recommendation”) if the INX Board of Directors concludes in good faith after consultation with its outside legal counsel and financial advisors that its failure to make such a Change in the INX Recommendation would be inconsistent with its fiduciary obligations; provided, however, that if any such action is (x) not in response to an Acquisition Proposal, then a Change in the INX Recommendation may be made only if directly related to an event, fact, circumstance, development or occurrence that affects the assets or operations of INX that is unknown to the INX Board of Directors as of the date of this Agreement but becomes known to the INX Board of Directors prior to obtaining approval of the Merger from the holders of Common Shares or (y) in response to an Acquisition Proposal (that was not solicited in breach of this Section 5.3) and which is determined by the INX Board of Directors in good faith after consultation with outside legal counsel and its financial advisors to be a Superior Proposal, prior to making any Change in the INX Recommendation or terminating this Agreement in accordance with Section 7.1(d)(ii), INX shall, in all such cases, (A) provide Parent with at least four Business Days advance written notice (such period, the “Notice Period”), advising Parent of its intention to make a Change in the INX Recommendation or to terminate this Agreement to enter into a definitive agreement with respect to a Superior Proposal, (B) if applicable, provide Parent in writing the material terms and conditions of such Superior Proposal (including the identity of the Person making such Superior Proposal) and a copy of the relevant proposed transaction documents with the party making such Superior Proposal and other material documents, (C) negotiate, and cause its advisors to negotiate, in good faith with Parent during the Notice Period, to the extent Parent wishes to negotiate, to enable Parent to make such proposed changes to the terms of this Agreement as to permit the INX Board of Directors to proceed with its recommendation of this Agreement and the Merger and (D) following the Notice Period, and taking into account any revised proposal made by Parent since the commencement of the Notice Period, the INX Board of Directors concludes in good faith after consultation with its outside legal counsel and financial advisors that its failure to make such a Change in the INX Recommendation would be inconsistent with its fiduciary obligations. Any material amendment to the financial terms or any other material amendment of such Superior Proposal shall require a new Notice Period and INX shall be required to comply again with the requirements of this Section 5.3(c); provided, however, that references to the four Business Day period above shall be deemed to be references to a three Business Day period. Notwithstanding anything in this Agreement to the contrary, disclosure by INX of any Acquisition Proposal and the operation of this Agreement with respect thereto shall not be deemed to be a Change in the INX Recommendation. “Superior Proposal” means an Acquisition Proposal (except that each instance of 20% shall be changed to 50% for purposes of this sentence) that the INX Board of Directors determines, in good faith after consultation with its financial advisor and outside legal counsel and consideration of all terms and conditions of such Acquisition Proposal, including the form of consideration, conditionality and the timing and likelihood of consummation of such Acquisition Proposal, to be more favorable to the holders of Common Shares, including from a financial point of view, than those set forth in this Agreement or the terms of any other proposal or revised proposal made by Parent. Upon receipt of any Acquisition Proposal, INX will provide reasonably prompt written notice to Parent advising Parent of such Acquisition Proposal (including the identity of the party making such Acquisition Proposal) and provide Parent with a summary of the material terms of such Acquisition Proposal.

(d) Except as may relate to any Excluded Party until the Cut-off Date or as expressly permitted by this Section 5.3, from and after the No-Shop Period Start Date until the Effective Time or, if earlier, the termination of this Agreement in accordance with Article VII, INX agrees that it will, and will cause its Representatives to, (i) immediately cease and cause to be terminated any activities, discussions or negotiations existing as of the date of this Agreement with any Person (other than Parent) conducted heretofore with respect to any actual or potential Acquisition Proposal and (ii) with respect to parties with whom discussions have been terminated, INX shall use its reasonable best efforts to obtain the return or the destruction of, in accordance with the terms of the applicable confidentiality agreement, confidential information previously furnished by INX or its Representatives.

(e) Nothing contained in this Agreement shall prohibit INX or the INX Board of Directors from (i) disclosing to its stockholders a position contemplated by Rule 14d-9 or 14e-2(a) promulgated under the Exchange Act or (ii) making any required disclosure to the stockholders of INX if, in the good faith judgment of the INX Board of Directors, after consultation with outside legal counsel, failure to do so would constitute a violation of Applicable Law.

(f) Any action pursuant to, and not in violation of, Section 5.3(a), (b), (c), (d) or (e) shall not constitute a breach of INX’s representations, warranties or covenants in this Agreement.

Section 5.4 Directors’ and Officers’ Indemnification and Insurance.

(a) The certificate of incorporation and bylaws of the Surviving Corporation shall contain provisions no less favorable to the Persons covered thereby with respect to exculpation, indemnification and advancement of expenses than are set forth in the certificate of incorporation and bylaws of INX as of the date of this Agreement, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would affect adversely the rights thereunder of individuals who at any time from and after the date of this Agreement and to and including the Effective Time were directors, officers, employees, fiduciaries or agents of INX in respect of actions or omissions occurring at or prior to the Effective Time (including, without limitation, the matters contemplated by this Agreement).

(b) From and after the Effective Time, the Surviving Corporation shall, to the fullest extent permitted under Applicable Law, indemnify, hold harmless and advance expenses to each present and former director or officer of INX (collectively, the “Indemnified Parties”) against all costs and expenses (including attorneys’ fees), judgments, fines, losses, claims, damages, inquiries, liabilities and settlement amounts paid in connection with any threatened or actual claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), whether civil, criminal, administrative or investigative, arising out of or pertaining to any action or omission in their capacity as a director or officer (including, without limitation, any claim, action, suit, proceeding or investigation arising out of this Agreement or any of the Transactions), whether occurring before or after the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, for a period of six years after the Effective Time, in each case to the fullest extent permitted under Applicable Law (and shall pay any expenses in advance of the final disposition of any such claim, action, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted under Applicable Law, upon receipt from the Indemnified Party to whom expenses are advanced of an undertaking to repay such advances as required under Applicable Law). In the event of any such claim, action, suit, proceeding or investigation, provided, further, that the Surviving Corporation shall not be obligated pursuant to this Section 5.4(b) to pay the fees and expenses of more than one counsel (plus appropriate local counsel) for all Indemnified Parties in any single action unless there is, as determined by counsel to the Indemnified Parties, under applicable standards of professional conduct, a conflict or a reasonable likelihood of a conflict on any significant issue between the positions of any two or more Indemnified Parties, in which case such additional counsel (including local counsel) as may be required to avoid any such conflict or likely conflict may be retained by the Indemnified Parties at the expense of the Surviving Corporation; and provided, further, that, in the event that any claim for indemnification is asserted or made prior to the Effective Time or within such six-year period, all rights to indemnification in respect of such claim shall continue until the final disposition of such claim. The Surviving Corporation shall pay all reasonable expenses, including attorneys’ fees, that may be incurred by any Indemnified Party in enforcing the indemnity and other obligations provided in this Section 5.4.

(c) From and for a period of six years after the Effective Time, the Surviving Corporation shall maintain in effect the current directors’ and officers’ liability insurance policies maintained by INX (provided, that the Surviving Corporation may substitute therefor policies of at least the same coverage and amounts containing terms and conditions that are no less advantageous to such officers and directors, so long as such substitution does not result in gaps or lapses in coverage) with respect to matters occurring prior to the Effective Time; provided, however, that in no event shall the Surviving Corporation be required to expend pursuant to this Section 5.4(c) more than an amount per year equal to 200% of current annual premiums paid by INX for such insurance and, in the event the cost of such coverage shall exceed that amount, the Surviving Corporation shall purchase as much coverage as possible for such amount.

(d) In the event the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving company or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation shall assume the obligations set forth in this Section 5.4.

(e) The obligations of the Surviving Corporation under this Section 5.4 shall not be terminated or modified in such a manner as to adversely affect any director or officer to whom this Section 5.4 applies without the consent of each affected director or officer (it being expressly agreed that the directors and officers to whom this Section 5.4 applies shall be third-party beneficiaries of, and entitled to the rights of third-party beneficiaries under, this Section 5.4). The rights of each Indemnified Party hereunder shall be in addition to any other rights such Indemnified Party may have under the certificate of incorporation or bylaws of INX, under Delaware Law or otherwise.

(b) INX shall use its reasonable best efforts to obtain prior to the Closing, and deliver to Parent at or prior to the Closing, and Parent shall use its reasonable best efforts to assist INX in obtaining, all consents, waivers and approvals under each contract, agreement or instrument listed or described on Section 2.5(a) or 2.5(b) of the INX Schedule (and any contract, agreement or instrument entered into after the date of this Agreement that would have been required to be listed or described on Section 2.5(a) or 2.5(b) of the INX Schedule, if entered into prior to the date of this Agreement).

(d) Each of INX and Parent (and, as applicable, Sub) shall furnish the other party with copies of all correspondence, filings and communications (and memoranda setting forth the substance thereof) between it and its affiliates and Representatives on the one hand, and any Governmental Authority or members of any such Governmental Authority’s staff on the other hand, with respect to this Agreement and the Transactions.

(e) In furtherance and not in limitation of the covenants of the parties contained in this Section 5.6, if any administrative or judicial action or proceeding, including any proceeding by a private party, is instituted (or threatened to be instituted) challenging the Merger or any other Transaction, INX and Parent (and, as applicable, Sub) shall each cooperate in all respects with each other and shall use their respective reasonable best efforts to contest and resist any such action or proceeding and to have vacated, lifted, reversed or overturned any decree, judgment, injunction or other order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the Merger or any other Transaction. Notwithstanding the foregoing or any other provision of this Agreement, nothing in this Section 5.6 shall limit a party’s right to terminate this Agreement pursuant to Section 7.1(b)(i) or (ii) so long as such party has, prior to such termination, complied with its obligations under this Section 5.6.

Section 5.7 Public Announcements. On the date of this Agreement, Parent and INX shall issue a joint press release with respect to the execution of this Agreement and the Merger, which press release shall be reasonably satisfactory to Parent and INX.

Parent and INX agree that, for the period beginning as of the Effective Time and ending on the one-year anniversary of the Effective Time, the base salary provided to each Continuing Employee shall be no less than the base salary provided to each such Continuing Employee immediately prior to the Effective Time, and Continuing Employees shall receive substantially comparable employee benefits in the aggregate as the employee benefits provided to such Continuing Employees immediately prior to the Effective Time but not taking into account any termination of a defined contribution plan as contemplated under Section 5.13. Parent shall deem, and shall cause the Surviving Corporation to deem, the period of employment with INX (and with predecessor employers with respect to which INX shall have granted service credit) to have been employment and service with Parent and the Surviving Corporation for purposes of eligibility, vesting and calculating vacation and severance benefits to the extent applicable and previously recognized by INX for similar purposes (other than benefit accrual under a defined benefit pension plan) for all of Parent’s and the Surviving Corporation’s employee benefit plans, programs, policies or arrangements similar to such INX Employee Benefit Plans and for similar purposes to the extent employment or service with Parent or the Surviving Corporation is recognized under any such plan, program, policy or arrangement.

(b) Under any plan of Parent or the Surviving Corporation that is substantially equivalent to an INX Employee Benefit Plan that it replaces (“Replacement Plan”) and which is also a medical or dental plan, there shall be waived, and Parent or the Surviving Corporation shall cause the relevant insurance carriers and other third parties to waive, all pre-existing conditions, restrictions and limitations for any medical condition existing as of the Effective Time of any of such employees and their eligible dependents for the purpose of any such plans, but only to the extent that such condition would be covered by the relevant INX Employee Benefit Plan and only to the extent of comparable coverage in effect immediately prior to the Effective Time. Further, if Parent offers employees of INX coverage under a Replacement Plan which is a group health plan, such employees shall be credited with amounts under such Replacement Plan towards the deductibles, copayments and out-of-pocket maximums imposed under such Replacement Plan, for the year during which the Effective Time occurs, with any deductibles, copayments and out-of-pocket maximums already incurred during such year under the relevant INX Employee Benefit Plan.

Section 5.10 Rule 16b-3. Prior to the Effective Time, INX and the INX Board of Directors or committees thereof shall use their reasonable best efforts to take all actions to cause any dispositions of the Common Shares (including derivative securities with respect thereto) resulting from the Transactions by each individual who is subject to the reporting requirements of Section 16(a) of Exchange Act to be exempt from Section 16(b) of the Exchange Act under Rule 16b-3 under the Exchange Act.

Section 5.11 Nasdaq De-listing. Parent and INX shall each use its reasonable best efforts to take, or cause to be taken, all actions, and do or cause to be done all things, reasonably necessary, proper or advisable on its part under Applicable Law and the rules and policies of Nasdaq to enable the de-listing by the Surviving Corporation of the Common Shares from the Nasdaq Global Market and the deregistration of the Common Shares under the Exchange Act, as promptly as practicable after the Effective Time.

Section 5.12 Cooperation with Financing. Prior to the Effective Time, INX shall provide and shall use reasonable best efforts to cause its Representatives to provide all necessary or customary cooperation as may be requested by Parent in connection with adding INX from and after the Closing as a guarantor and credit party under the Credit Agreement dated as of March 31, 2011 by and among Presidio IS Corp., Presidio Merger Sub LLC, PNC Bank, National Association, and other parties named thereto (the “Parent Financing”), including (a) delivering to Parent information with respect to INX as is reasonably requested in connection with the Parent Financing; (b) facilitating the pledge and perfection of liens from and after the Closing securing the Parent Financing; and (c) taking all other actions as are reasonably requested by Parent to facilitate the satisfaction on a timely basis of all conditions to obtaining the Parent Financing

Section 5.13 Defined Contribution Pension Plan. At the request of Parent no later than five (5) days prior to the Effective Time, INX will take all actions necessary to terminate its defined contribution pension plan immediately prior to and contingent on the Closing. With respect to a Replacement Plan that is a defined contribution plan (as defined in section 3(34) of ERISA) in which the Continuing Employees are eligible to participate, Parent shall take all actions necessary to allow the Continuing Employees to make eligible rollover contributions to such Replacement Plan of their account balances (in cash and in loan notes, if any, evidencing loans to such Continuing Employees as of the date of distribution) from any defined contribution plan terminated pursuant to this Section 5.13 as soon as practicable after the Closing.

(c) INX shall have received a certificate signed on behalf of Parent by an executive officer of Parent to the effect that the conditions in Sections 6.3(a) and (b) above have been so satisfied.

Section 6.4 Frustration of Closing Conditions. Neither Parent, Sub nor INX may rely upon the failure of any condition set forth in Section 6.1, Section 6.2 or Section 6.3, as the case may be, to be satisfied if such failure was caused by such party’s failure to use its reasonable best efforts to consummate the Transactions, as required by and subject to Section 5.6.

ARTICLE VII

TERMINATION, AMENDMENT AND WAIVER

Section 7.1 Termination. This Agreement may be terminated and the Merger may be abandoned at any time prior to the Effective Time, notwithstanding the adoption of this Agreement by the holders of Common Shares:

(a) by mutual written agreement of Parent, Sub and INX; or

(b) by Parent or INX, if:

(i) the Merger shall not have been consummated on or before March 30, 2012 (the “Outside Date”); provided, however, that neither Parent, on the one hand, nor INX, on the other hand, shall be entitled to terminate this Agreement under this Section 7.1(b)(i) if such party (or, in the case of Parent, Parent or Sub) is in material breach of any of its representations, warranties or covenants in this Agreement;

(ii) a court of competent jurisdiction or other Governmental Authority shall have issued a final, non-appealable order, decree or ruling permanently restraining, enjoining or otherwise prohibiting the Merger; provided that the party seeking to terminate this Agreement pursuant to this Section 7.1(b)(ii) shall have complied in all material respects with its obligations in Section 5.6; or

(iii) this Agreement shall not have been adopted by the holders of Common Shares by reason of the failure to obtain the requisite vote at an INX Shareholders’ Meeting; or

(i) INX shall have materially breached or materially failed to perform any of its representations, warranties or covenants in this Agreement such that the conditions set forth in Sections 6.2(a) or (b) are not capable of being satisfied, and such breach or failure to perform shall not have been cured prior to the earlier of (A) 30 days following notice of such breach or failure given by Parent to INX and (B) the Outside Date; provided that Parent shall have no right to terminate this Agreement pursuant to this Section 7.1(c)(i) if Parent or Sub is then in material breach or has materially failed to perform any of its representations, warranties or covenants in this Agreement; or

(ii) prior to obtaining the INX Shareholder Approval, the INX Board of Directors shall have effected a Change in the INX Recommendation; or

(d) by INX, if:

(i) Parent or Sub shall have materially breached or materially failed to perform any of their representations, warranties or covenants in this Agreement such that the conditions set forth in Sections 6.3(a) or (b) are not capable of being satisfied, and such breach or failure to perform shall not have been cured prior to the earlier of (A) 30 days following notice of such breach or failure given by INX to Parent and (B) the Outside Date; provided that INX shall not have the right to terminate this Agreement pursuant to this Section 7.1(d)(i) if INX is then in material breach or has materially failed to perform any of its representations, warranties or covenants in this Agreement; or

(ii) prior to obtaining the INX Shareholder Approval, the INX Board of Directors shall have effected or authorized a Change in the INX Recommendation as a result of a Superior Proposal pursuant to Section 5.3(c)(ii) and authorized INX to enter into a binding definitive agreement in respect of a Superior Proposal; provided, however, that such termination under this Section 7.1(d)(ii) shall not be effective unless (A) INX shall have complied in all material respects with the procedures set forth in Section 5.1 and 5.3 and (B) INX has made payment to Parent of the INX Termination Fee pursuant to Section 7.3(a).

Section 7.2 Effect of Termination. In the event that the Effective Time does not occur as a result of any party hereto exercising its rights to terminate pursuant to this Article VII, then this Agreement shall be null and void and, except for the provisions in this Section 7.2 and Sections 5.2(b), 7.3, 8.1, 8.3, 8.5, 8.6, 8.7, 8.8, 8.9, 8.10 or 8.11 or as otherwise expressly provided herein, no party shall have any rights or obligations under this Agreement, except that no such termination shall relieve any party from liability for damages for any willful and material breach of any agreement or covenant contained herein. In the event the termination of this Agreement results from the knowing and material breach of any agreement or covenant herein, then the Parent Parties or INX, as the case may be, shall be entitled to all remedies available at law or in equity and shall be entitled to recover court costs and reasonable attorneys’ fees in addition to any other relief to which it may be entitled.

Section 7.3 Fees and Expenses.

(a) If this Agreement is terminated pursuant to (i) Sections 7.1(b)(i), 7.1(b)(iii) or 7.1(c)(i) or (ii) Sections 7.1(c)(ii) or 7.1(d)(ii), then, in any such event, INX shall pay Parent $2,798,832 if such termination occurs under clause (ii) above and is either (A) made prior to the No-Shop Period Start Date or (B) with an Excluded Party on or after the No-Shop Period Start Date and prior to the Cut-off Date or $3,731,777 otherwise (the “Termination Fee”). Notwithstanding the foregoing, in the case of any termination pursuant to clause (i) of the preceding sentence, the Termination Fee shall be payable only if (x) after the date hereof and prior to such termination, an Acquisition Proposal (except that each instance of 20% shall be changed to 50%) is made known to INX or publicly announced by any Person (other than Parent or Sub) and (y) an Acquisition Proposal (except that each instance of 20% shall be changed to 50%) is consummated or INX enters into an acquisition agreement for an Acquisition Proposal (except that each instance of 20% shall be changed to 50%) with any Person, in any case, within 12 months following such termination, in which case such payment shall be made prior to or contemporaneous with the consummation of, or entering into an acquisition agreement for, an Acquisition Proposal (except that each instance of 20% shall be changed to 50%). Such amount shall be paid in cash by wire transfer in immediately available funds not later than two Business Days after the occurrence of such termination. In no event shall Parent be entitled to receive more than one payment of the Termination Fee. INX acknowledges that (i) the agreements contained in this Section 7.3(a) are an integral part of the Transactions, (ii) the amount of, and the basis for payment of, the fees described herein is reasonable and appropriate in all respects and (iii) without this agreement, Parent would not enter into this Agreement. Accordingly, if INX fails to pay in a timely manner the fees due pursuant to this Section 7.3(a), and, in order to obtain such payment, Parent makes a claim that results in a judgment for the amounts set forth in this Section 7.3(a), INX shall pay to Parent its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit.

(b) All costs and expenses incurred in connection with this Agreement and the Merger shall be paid by the party incurring such expenses, whether or not the Merger is consummated; provided that INX shall pay all of Parent’s reasonably documented out-of-pocket expenses not to exceed $1,980,000 if this Agreement is terminated pursuant to Sections 7.1(b)(iii) or 7.1(c)(i); provided further that any amounts paid by INX to Parent pursuant to this Section 7.3(b) shall reduce on a dollar-for-dollar basis any Termination Fee that becomes due and payable pursuant to Section 7.3(a).

Section 7.4 Amendment. This Agreement may be amended by the parties hereto by action taken by or on behalf of their respective boards of directors at any time prior to the Effective Time; provided, however, that after the INX Shareholder Approval has been obtained, no amendment shall be made unless the further approval by the holders of Common Shares is obtained, if such approval is required pursuant to Applicable Law. This Agreement may not be amended except by an instrument in writing signed by the parties hereto.

Section 7.5 Waiver. At any time prior to the Effective Time, the Parent Parties, on one hand, or INX, on the other hand, may (i) extend the time for the performance of any obligation or other act of INX or the Parent Parties, respectively, hereto, (ii) waive any inaccuracy in the representations and warranties of INX or the Parent Parties, respectively, contained herein or in any document delivered pursuant hereto and (iii) waive compliance with any agreement or condition contained herein applicable, respectively, to INX or the Parent Parties. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party or parties to be bound thereby.

ARTICLE VIII

GENERAL PROVISIONS

Section 8.1 Survival. The agreements in Articles I and VIII and Sections 5.4, 5.8 and 5.9 of this Agreement shall survive the Merger. This Article VIII and the agreements made by the parties hereto in Sections 5.2(b), 5.7, 5.8, 7.2 and 7.3 of this Agreement shall survive the termination of this Agreement. The remainder of the representations, warranties and agreements in this Agreement or in any schedule, exhibit, instrument or other document delivered pursuant to this Agreement shall terminate at the earlier of the Effective Time or the time of termination of this Agreement pursuant to Section 7.1.

Section 8.2 Scope of Representations and Warranties.

(a) Except as and to the extent expressly set forth in this Agreement, INX makes no, and disclaims any, representations or warranties whatsoever, whether express or implied, and Parent and Sub confirm they are not relying upon any such representation or warranty not expressly set forth in this Agreement. Except in the case of intentional fraud, INX disclaims all liability or responsibility for any other statement or information made or communicated (orally or in writing) to Sub, Parent, their affiliates or any shareholder, officer, director, employee, representative, consultant, attorney, agent, lender or other advisor of Sub, Parent or their affiliates (including, but not limited to, any opinion, information or advice which may have been provided to any such Person by any representative of INX or any other Person or contained in the files or records of INX), wherever and however made, including any documents, projections, forecasts or other material made available to Parent and its Subsidiaries in certain “data rooms” or management presentations in expectation of the Transactions.

(b) In connection with investigation by Parent of INX, Parent has received or may receive from INX certain projections, forward-looking statements and other forecasts and business plan information. Parent acknowledges that there are uncertainties inherent in attempting to make such estimates, projections and other forecasts and plans, that Parent is familiar with such uncertainties, that Parent is taking full responsibility for making its own evaluation of the adequacy and accuracy of all estimates, projections and other forecasts and plans so furnished to it (including the reasonableness of the assumptions underlying such estimates, projections, forecasts or plans), and that, absent fraud or willful misrepresentation, Parent shall have no claim against anyone with respect thereto. Accordingly, Parent acknowledges that INX makes no representation or warranty with respect to such estimates, projections, forecasts or plans (including the reasonableness of the assumptions underlying such estimates, projections, forecasts or plans).

(c) Except as and to the extent expressly set forth in this Agreement, neither Sub nor Parent makes, and each disclaims, any representations or warranties whatsoever, whether express or implied. Except in the case of intentional fraud, each of Sub and Parent disclaims all liability and responsibility for any other statement or information made or communicated (orally or in writing) to INX, its affiliates or any shareholder, officer, director, employee, representative, consultant, attorney, agent, lender or other advisor of INX or its affiliates (including, but not limited to, any opinion, information or advice which may have been provided to any such Person by any representative of Sub or Parent or any other Person), wherever and however made, including any documents, projections, forecasts or other material made available to Parent and its Subsidiaries in certain “data rooms” or management presentations in expectation of the Transactions.

(d) Any representation “to the knowledge” of a party or phrases of similar wording shall be limited to matters within the actual conscious awareness of the Persons listed on Exhibit 8.2 attached hereto.

Section 8.3 Notices. All notices, requests, claims, demands and other communications hereunder shall be in writing and shall be given (and shall be deemed to have been duly given upon receipt) by delivery in Person, by email, cable, telecopy, facsimile, telegram or telex or by registered or certified mail (postage prepaid, return receipt requested) to the respective parties at the following addresses (or at such other address for a party as shall be specified in a notice given in accordance with this Section 8.3):

(c) “Business Day” means any day, other than Saturday, Sunday or a federal holiday, and shall consist of the time period from 12:01 a.m. through 12:00 midnight Central time. In computing any time period under this Agreement, the date of the event which begins the running of such time period shall be included except that if such event occurs on other than a Business Day such period shall begin to run on and shall include the first Business Day thereafter

(d) “control” (including the terms “controlled by” and “under common control with”) means the possession, directly or indirectly, or as trustee or executor, of the power to direct or cause the direction of the management and policies of a Person, whether through the ownership of voting securities, as trustee or executor, by contract or credit arrangement or otherwise;

(i) “Subsidiary” or “Subsidiaries” means an affiliate controlled by a Person, directly or indirectly, through one or more intermediaries.

Section 8.5 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Transactions is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the Transactions are consummated as originally contemplated to the fullest extent possible. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

Section 8.6 Entire Agreement; Assignment. This Agreement, the INX Schedule, the Parent Schedule and the Exhibits hereto, constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof, except that the Confidentiality Agreement shall remain in full force and effect. Neither this Agreement nor any of the rights, interests or obligations set forth herein shall be assigned by any party hereto without the prior written consent of the other parties hereto and any purported assignment without such consent shall be void; provided, however, that at any time prior to or in connection with the Closing, Parent may assign any of its rights, interests and obligations under this Agreement to one of its Subsidiaries without the consent of any other party hereto; provided, further, that in any event, no assignment of any obligations hereunder shall relieve Parent of any of its obligations hereunder to consummate the Transactions or pay the Merger Consideration. Upon any such permitted assignment, the references in this Agreement to Parent shall apply to any such assignee unless the context otherwise requires.

Section 8.7 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than Sections 5.4 and 5.9 and, from and after the Effective Time, Sections 1.6 and 1.7 (all of which are intended to be for the benefit of the Persons covered thereby and may be enforced by such Persons).

Section 8.8 Specific Performance.

(a) The parties hereto agree that irreparable damage would occur in the event that any provision of this Agreement was not performed in accordance with its specific terms or was otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof without the securing or posting of any bond, this being in addition to any other remedy to which they are entitled at law or in equity. No party shall object to the other parties’ right to specific performance as a remedy for breach of this Agreement.

(b) INX hereby agrees that specific performance as provided for in Section 8.8(a) shall be its sole and exclusive remedy with respect to breaches by Parent, Sub, or any other Person or otherwise in connection with this Agreement or the Transactions (whether in contract, tort or otherwise) and except as provided in Section 8.8(c), that it may not seek or accept any other form of relief that may be available for breach under this Agreement or otherwise in connection with this Agreement or the Transactions (including monetary damages).

(c) If a court of competent jurisdiction has declined to specifically enforce the obligations of Parent, Sub, or any other Person or otherwise in connection with this Agreement or the Transactions pursuant to a claim for specific performance brought against Parent pursuant to this Section 8.8 and has instead granted an award of damages for such alleged breach against Parent, Sub, or any other Person or otherwise in connection with this Agreement or the Transactions, INX may enforce such award and accept damages for such alleged breach only if, within two weeks following such determination INX (i) confirms to Parent in writing that it is prepared and willing to consummate the Merger in accordance with this Agreement, and (ii) Parent is not willing to consummate the Merger within such two week period in accordance with the terms and conditions of this Agreement. In addition, INX agrees to cause any legal proceeding still proceeding to be dismissed with prejudice at such time as Parent consummates the Merger in accordance with Article I of this Agreement.

Section 8.9 Governing Law; Jurisdiction and Venue. This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of Delaware, without giving effect to any choice or conflict of law provisions or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of laws of any jurisdiction other than those of the State of Delaware. All actions and proceedings arising out of or relating to this Agreement may be heard and determined in any federal court sitting in the State of Delaware, or any state court sitting in the State of Delaware, and each of INX, Parent and Sub hereby irrevocably and unconditionally consents to submit to the jurisdiction of such courts for any litigation arising out of or relating to this Agreement and the Transactions (and agrees not to commence any litigation relating thereto except in such court), waives any objection to the laying of venue of any such litigation in such courts and agrees not to plead or claim that such litigation brought therein has been brought in any inconvenient forum.

Section 8.10 WAIVER OF JURY TRIAL. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 8.10.

Section 8.11 Headings. The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 8.12 Interpretation.

(a) When a reference is made in this Agreement to Articles, Sections, Exhibits or Schedules, such reference shall be to an Article or Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereby,” “herein,” “hereof” or “hereunder,” and similar terms are to be deemed to refer to this Agreement as a whole and not to any specific section. The inclusion of any information in the INX Schedule shall not be deemed an admission or acknowledgment by INX, solely by virtue of the inclusion of such information therein, that such information is required to be included therein or material to INX. The disclosure of information in the INX Schedule as an exception to, or for purposes of, a representation, warranty or covenant in this Agreement shall be deemed adequately disclosed as an exception to, or for purposes of, all other representations, warranties and covenants herein to which the relevance of such information is reasonably apparent on its face. The specification of any dollar amount in the representations and warranties or otherwise in this Agreement or in the INX Schedule is not intended and shall not be deemed to be an admission or acknowledgment of the materiality of such amounts or items, nor shall the same be used in any dispute or controversy between the parties to determine whether any obligation, item or matter (whether or not described herein or included in any schedule) is or is not material for purposes of this Agreement.

(b) The phrase “the date of this Agreement,” “date hereof” and terms of similar import, unless the context otherwise requires, shall be deemed to refer to November 1, 2011.

(c) Any statute, rule or regulation defined or referred to herein means such statute, rule or regulation as from time to time amended, modified or supplemented, including by succession of comparable successor statutes, rules and regulations and references to all attachments thereto and instruments incorporated therein.

(d) The parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

Section 8.13 Incorporation of Exhibits. The exhibits attached hereto and referred to herein are hereby incorporated herein and made a part hereof for all purposes as if fully set forth herein.

Section 8.14 Counterparts. This Agreement may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.
