 This AGREEMENT AND PLAN OF MERGER, dated as of January 8, 2006 (this “Agreement”), is by and among Mercury Interactive
Corporation, a Delaware corporation (“Mercury”), Systinet Corporation, a Delaware corporation (“Systinet”), Shark Corporation, a Delaware corporation and a wholly owned subsidiary of Mercury
(“Merger Sub”), and Warburg Pincus Private Equity VIII, L.P., as a representative of Systinet’s stockholders (the “Stockholders Representative”). 
 BACKGROUND 
 A. Mercury, Merger Sub
and Systinet wish to effect a business combination through a Merger (as defined in Section 1.1) of Merger Sub with and into Systinet on the terms and conditions, set forth in this Agreement; 
 B. The Board of Directors of Systinet (the “Systinet Board”) has approved this Agreement, the Merger and the other transactions
contemplated by this Agreement and determined that this Agreement, the Merger and the other transactions contemplated by this Agreement are advisable and in the best interest of its stockholders; 
 C. The Boards of Directors of Mercury and Merger Sub have approved this Agreement, the Merger and the other transactions contemplated by this Agreement
and determined that this Agreement, the Merger and the other transactions contemplated by this Agreement are in the best interest of their respective stockholders; 
 D. Immediately after the execution and delivery of this Agreement, stockholders of Systinet holding at least 85% of the combined voting power of the then outstanding shares of Systinet Capital Stock (as defined in
Section 1.4) will execute and deliver a written consent in the form of Exhibit A (the “Systinet Stockholders Written Consent”) approving and adopting this Agreement; and 
 E. Mercury, Merger Sub and Systinet desire to make certain representations, warranties, covenants and agreements in connection with the Merger, and also
to prescribe various conditions to the Merger. 
 AGREEMENT 
 The parties to this Agreement, intending to be legally bound, agree as follows: 
 ARTICLE 1 
 THE MERGER 
 1.1 The Merger. Upon the terms and subject to the conditions in this Agreement, and in accordance with the General Corporation Law of the State of
Delaware (the “DGCL”), Merger Sub shall be merged with and into Systinet (the “Merger”) at the effective time of the Merger (the “Effective Time”) which shall be the time of the
filing of the certificate of merger, substantially in the form of Exhibit B (the “Certificate of Merger”) or at such later time as is agreed by Mercury and Systinet as set forth in the Certificate of Merger. The
Certificate of 

 Merger shall be filed if, as and when the Closing occurs with the Secretary of State of the State of Delaware (the
“Delaware Secretary”). Systinet shall be the surviving corporation (sometimes referred to as the “Surviving Corporation”) in the Merger and shall succeed to and assume all the rights and obligations of
Merger Sub in accordance with the DGCL. 
 1.2 Closing. The closing of the transactions contemplated by this Agreement (the
“Closing”) shall take place no more than three business days after the satisfaction or waiver of each of the conditions set forth in Article 5 or at such other time as the parties agree in writing. The Closing shall take
place at the offices of Jones Day, 2882 Sand Hill Road, Suite 240, Menlo Park, California or at such other location as the parties agree. The date on which the Closing actually occurs is herein referred to as the “Closing
Date.” 
 1.3 Effects of the Merger. 
 (a) At the Effective Time, the effect of the Merger shall be as provided in this Agreement, the Certificate of Merger and the applicable provisions of the DGCL. 
 (b) At the Effective Time, the certificate of incorporation of Merger Sub, as in effect immediately prior to the Effective Time, shall be the certificate
of incorporation of the Surviving Corporation until thereafter amended as provided by the DGCL and such certificate of incorporation; provided, however, that at the Effective Time the certificate of incorporation of the Surviving
Corporation shall be amended so that the name of the Surviving Corporation shall be “Systinet Corporation.” 
 (c) At the Effective
Time, the bylaws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Corporation until thereafter amended as provided by the DGCL, the certificate of incorporation of the Surviving Corporation
and such bylaws. 
 (d) At the Effective Time, the directors and officers of Merger Sub, as constituted immediately prior to the Effective
Time, shall be the directors and officers of the Surviving Corporation, for so long as provided under the DGCL, the certificate of incorporation of the Surviving Corporation and the bylaws of the Surviving Corporation. 
 1.4 Effects on Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of Merger Sub, Mercury or
Systinet, or any holder of shares of capital stock of Systinet (the “Systinet Capital Stock”) or any shares of capital stock of Merger Sub, the following shall occur: 
 (a) Each share of Systinet Capital Stock that is owned by Systinet, Mercury, Merger Sub or any of their respective Subsidiaries shall automatically be
canceled and shall cease to exist, and no consideration shall be delivered or deliverable in exchange therefor. 
 (b) Each share of Common
Stock of Merger Sub (the “Merger Sub Common Stock”) issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock of the
Surviving Corporation. Each certificate evidencing ownership of Merger Sub Common Stock shall evidence ownership of shares of common stock of the Surviving Corporation. 
  

 2 

 (c) Each issued and outstanding share of Systinet Capital Stock (other than shares to be canceled in
accordance with Section 1.4(a) and Dissenting Shares (as defined in Section 1.7(a))) shall be converted into the right to receive the Merger Consideration (as defined in Section 1.4(d)) as specified and allocated in this
Section 1.4. As of the Effective Time, all such shares of Systinet Capital Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate formerly representing any such shares
of Systinet Capital Stock (the “Certificates”) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration as allocated in this Section 1.4 upon surrender of such Certificate
in accordance with Section 1.5 or, with respect to Dissenting Shares, the rights set forth in Section 1.7 and the DGCL. 
 (d)
“Merger Consideration” means an aggregate amount of cash in immediately available funds equal to (i) $105,000,000 plus (ii) the amount of the aggregate exercise price of all vested and unexercised Systinet Options
(as defined in Section 1.6(a)) and all Systinet Warrants (as defined in Section 1.6(c)) as of 12:01 a.m. on the Closing Date (the “Aggregate Exercise Price”) minus (iii) the amount of the Actual Net Liabilities
(as defined in Section 1.8(e)). At or before the Closing, Mercury shall deliver in cash in immediately available funds: 
 (x) A portion
of the Merger Consideration equal to $10,750,000 (the “Escrow Fund”) to U.S. Bank National Association, as escrow agent (the “Escrow Agent”), in accordance with an Escrow Agreement, dated as of the
Closing Date, substantially in the form of Exhibit C (the “Escrow Agreement”), by and among Mercury, the Escrow Agent and the Stockholders Representative, which Escrow Fund will be held and distributed in
accordance with the terms of the Escrow Agreement and Section 1.8(f) and Article 7 of this Agreement; and 
 (y) An amount equal to the
Merger Consideration less the amount of the Escrow Fund to the Exchange Agent (as defined in Section 1.5(a)) for distribution in accordance with this Section 1.4 and Sections 1.5 and 1.6. 
 (e) For purposes of the Closing, Systinet shall make a good-faith estimate of (i) the consolidated balance sheet of Systinet as of 12:01 a.m. on the
Closing Date (the “Closing Date Balance Sheet”), which shall be prepared in accordance with GAAP (as defined in Section 2.4) applied in a manner consistent with the accounting principles used in the preparation of the
Audited Financial Statements (as defined in Section 2.4), (ii) the consolidated balance sheet of Systinet as of December 31, 2005 (the “December 31 Balance Sheet”), which shall be prepared in accordance with
GAAP applied in a manner consistent with the accounting principles used in the preparation of the Audited Financial Statements (as defined in Section 2.4), (iii) the Net Liabilities (as defined in Section 8.4(j)) (or, for accounts
receivable, as of December 5, 2005) (the “Estimated Net Liabilities”), and (iv) the Aggregate Exercise Price as of December 31, 2005 (the “Estimated Aggregate Exercise Price”), each of
which shall be based upon the most recent ascertainable financial information of Systinet and its Subsidiaries, and each of which shall be delivered to Mercury at least three business days prior to the Closing. For purposes of payments of the Merger
Consideration before a final determination of the Actual Net Liabilities and the Aggregate Exercise Price in accordance with Section 1.8, the Merger Consideration shall be calculated using the Estimated Net Liabilities and the Estimated
Aggregate Exercise Price, with any adjustment to be made in accordance with Section 1.8(f). 
  

 3 

 (f) The Merger Consideration shall be allocated as follows: (i) each share of Systinet Common Stock
(as defined in Section 8.4(o)) issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive, and become exchangeable for, an amount of cash equal to the Common Price Per Share, and (ii) each
share of Systinet Preferred Stock (as defined in Section 8.4(p)) issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive, and become exchangeable for, an amount in cash equal to the product of
(x) the Common Price Per Share multiplied by (y) the number of shares (including fractions of a share) of Systinet Common Stock issuable upon conversion of such share of Systinet Preferred Stock in accordance with Systinet’s
certificate of incorporation, as amended and as in effect immediately prior to the Effective Time (the “Systinet Charter”). The “Common Price Per Share” shall equal the Merger Consideration divided by
the Systinet Participating Capitalization, rounded to six decimal places. “Systinet Participating Capitalization” means, as of immediately prior to the Effective Time, the aggregate number of outstanding shares of Systinet
Common Stock (including all (i) shares of Systinet Common Stock issuable upon conversion of all shares of Systinet Preferred Stock and (ii) shares of Systinet Common Stock issuable upon exercise of (A) all vested and unexercised
Systinet Options and (B) all Systinet Warrants). 
 (g) If there is a stock split, reverse stock split, stock dividend (including any
dividend or distribution of securities convertible into capital stock), reorganization, reclassification, combination, recapitalization or other like change with respect to shares of Systinet Capital Stock occurring after the date of this Agreement
and before the Effective Time, all references in this Agreement to specified numbers of shares of any class or series affected thereby, and all calculations provided for that are based upon numbers of shares of any class or series (or trading prices
therefor) affected thereby, shall be equitably adjusted to the extent necessary to provide the parties the same economic effect as contemplated by this Agreement prior to such stock split, reverse stock split, stock dividend, reorganization,
reclassification, combination, recapitalization or other like change. 
 1.5 Exchange of Certificates. 
 (a) At or prior to the Closing, Mercury shall enter into an agreement with Mellon Investor Services LLC (or such other bank or trust company in the United
States as may be designated by Mercury and reasonably acceptable to Systinet, the “Exchange Agent”), which shall provide that Mercury shall make available to the Exchange Agent cash in the amount necessary for the payment of
the Merger Consideration as specified and allocated in Section 1.4 upon surrender of Certificates and thereafter. 
 (b) At the Closing
or as soon as reasonably practicable after the Closing, Mercury shall cause the Exchange Agent to deliver or mail to each holder of record of a Certificate (i) a letter of transmittal (which shall specify that delivery shall be effected, and
risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be substantially in the form of Exhibit D, together with changes reasonably requested by the Exchange Agent)
and (ii) instructions for use in surrendering Certificates in exchange for consideration specified and allocated in Section 1.4. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of
transmittal, duly completed and executed, and such other documents as may reasonably be required by the 
  

 4 

 Exchange Agent, the holder of such Certificate shall receive in exchange therefor the Merger Consideration into which the
shares formerly represented by such Certificate shall have been converted in accordance with Section 1.4 (less any cash deposited into the Escrow Fund), and the Certificate so surrendered shall be canceled. If a transfer of ownership of shares
of Systinet Capital Stock has not been registered in Systinet’s transfer records, payment may be made to a Person (as defined in Section 8.4(k)) other than the Person in whose name the Certificate so surrendered is registered if such
Certificate is properly endorsed or otherwise is in proper form for transfer and the Person requesting such issuance shall pay any transfer or other Tax (as defined in Section 2.9(a)) required by reason of the payment to a Person other than the
registered holder of such Certificate or establish to the satisfaction of Mercury that such Tax has been paid or is not applicable. Other than interest earned that becomes part of the Escrow Fund, no interest shall be paid or will accrue on the cash
payable to holders of Certificates in accordance with the provisions of this Article 1. 
 (c) All cash paid upon the surrender of
Certificates in accordance with the terms of this Article 1 (including cash deposited into the Escrow Fund) shall be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Systinet Capital Stock represented by such
Certificates, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Systinet Capital Stock which were outstanding immediately prior to the Effective Time. 
 (d) None of Mercury, the Surviving Corporation or the Exchange Agent shall be liable to any Person with respect to any cash delivered to a public
official in accordance with any applicable abandoned property, escheat or similar law. If any Certificate shall not have been surrendered immediately prior to the date on which any amounts payable in accordance with this Article 1 would otherwise
escheat to or become the property of any Governmental Entity (as defined in Section 2.3), 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. 
 (e) 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 Mercury, the posting by such Person of a bond in such reasonable amount as Mercury 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. 
 (f) To the extent required by law, the Surviving Corporation or the Exchange Agent shall be entitled to deduct and withhold from amounts otherwise
payable in accordance with this Agreement to any former holder of shares of Systinet Capital Stock, Systinet Options or Systinet Warrants such amounts as the Surviving Corporation or the Exchange Agent reasonably believes is required to be deducted
and withheld with respect to the making of such payment under the Internal Revenue Code of 1986 (the “Code”) or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld and paid over to the
appropriate taxing authority by the Surviving Corporation or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Systinet Capital Stock, Systinet Options or
Systinet Warrants in respect of which such deduction and withholding was made by the Surviving Corporation or the Exchange Agent. 
  

 5 

 1.6 Stock Options and Warrants. 
 (a) Systinet shall use its commercially reasonable efforts to obtain from each holder of a then outstanding option to purchase shares of Systinet Common
Stock (the “Systinet Options”) granted under the Systinet Option Plan (as defined in Section 2.2) that is then exercisable and vested (including those that become exercisable and vested as a result of the consummation of
the Merger) an agreement, to be effective upon consummation of the Merger, to cancel such Systinet Option to the extent it is then exercisable and vested (including those that become exercisable and vested as a result of the consummation of the
Merger) in consideration of payment to such holder of an amount in cash in respect thereof equal to the product of (i) the excess, if any, of the Common Price Per Share over the per share exercise price thereof and (ii) the number of then
exercisable and vested (including those that become exercisable and vested as a result of the consummation of the Merger) shares of Systinet Common Stock subject thereto (such payment to be net of applicable withholding taxes). The Systinet Options
subject to the agreements described in the preceding sentence shall be referred to as the “Cash Out Options.” 
 (b) Upon
consummation of the Merger, each then outstanding Systinet Option granted under the Systinet Stock Plan that is not a Cash Out Option shall be assumed by Mercury in accordance with Section 4.9 hereof. 
 (c) Systinet shall use its reasonable efforts to obtain from each holder of a then outstanding warrant issued by Systinet (the “Systinet
Warrants”) an agreement, to be effective upon consummation of the Merger, to cancel such Systinet Warrant in consideration of payment to such holder of an amount in cash in respect thereof equal to the product of (i) the excess, if
any, of the Common Price Per Share over the per share exercise price thereof and (ii) the number of shares of Systinet Common Stock subject thereto (such payment to be net of applicable withholding taxes). The Systinet Warrants subject to the
agreement described in the preceding sentence shall be referred to as the “Cash Out Warrants.” 
 (d) Payment of the consideration
for each Cash Out Option and Cash Out Warrant shall be made as follows: 
 (i) At the Closing, a portion of such consideration (before any
required tax withholding) equal to the product obtained by multiplying (x) such consideration by (y) a fraction, the numerator of which shall be the amount of the Escrow Fund and the denominator of which shall be the Merger Consideration
shall be included in the Escrow Fund delivered by Mercury to the Escrow Agent as contemplated by Section 1.4(d)(x); and 
 (ii) Within
10 business days after Closing, Mercury shall deliver to the holder of such Cash Out Option and Cash Out Warrant the remainder of such consideration. 
  

 6 

 1.7 Dissenting Shares. 
 (a) Notwithstanding anything in this Agreement to the contrary and unless otherwise provided by applicable law, shares of Systinet Capital Stock that are
issued and outstanding immediately prior to the Effective Time and that are owned by stockholders who have properly perfected their rights of appraisal in accordance with the provisions of applicable law (“Dissenting Shares”)
shall not be converted into the right to receive the Merger Consideration, unless and until such stockholders shall have failed to perfect or shall have effectively withdrawn or lost their right of payment under applicable law, but, instead, the
holders thereof shall be entitled to payment of the fair value of such Dissenting Shares in accordance with the applicable provisions of law. If any such holder shall have failed to perfect or shall have effectively withdrawn or lost such right of
appraisal, each share of Systinet Capital Stock held by such stockholder shall thereupon be deemed to have been converted into the right to receive and become exchangeable for, at the Effective Time, the Merger Consideration specified and allocated
in Section 1.4. 
 (b) Systinet shall give Mercury (i) prompt notice of any objections filed in accordance with applicable law
received by Systinet, withdrawals of such objections and any other instruments served in connection with such objections in accordance with applicable law and received by Systinet or its representatives and (ii) the opportunity to direct all
negotiations and proceedings with respect to objections under applicable law consistent with Systinet’s obligations thereunder. Systinet shall not, except with the prior written consent of Mercury, (i) voluntarily make any payment,
admission or statement against interest with respect to any such objection, (ii) offer to settle or settle any such objection or (iii) waive any failure by a former Systinet stockholder to timely deliver a written objection or other act
perfecting appraisal rights in accordance with applicable law. 
 1.8 Determination of Actual Net Liabilities and Aggregate Exercise
Price. 
 (a) Mercury may, at its option, prepare a calculation of (i) the actual Net Liabilities (or, for accounts receivable, as of
December 5, 2005) (the “Final Net Liabilities”), and (ii) the actual Aggregate Exercise Price as of December 31, 2005 (the “Final Aggregate Exercise Price”), which shall be delivered to
the Stockholders Representative, if at all, within 45 days after the Closing. In addition, if it is determined in accordance with such calculation that the Estimated Amount (as defined in Section 1.8(f)) is greater than the Actual Amount (as
defined in Section 1.8(f)), Mercury may, at its option, prepare a statement setting forth the amount equal to the difference between the Actual Amount and the Estimated Amount (an “Adjustment Certificate”), which shall
be delivered to the Stockholders Representative and the Escrow Agent, if at all, within 45 days after the Closing. The Stockholders Representative shall have 45 days after the date of the delivery of the Final Net Liabilities, the Final Aggregate
Exercise Price and the Adjustment Certificate (the “Dispute Period”) to dispute any of the elements of Mercury’s calculation of the Final Net Liabilities, the Final Aggregate Exercise Price or the amount set forth in the
Adjustment Certificate (a “Dispute”). The Stockholders Representative shall have reasonable access during normal business hours to all documents, records, work papers, facilities and personnel necessary for it to review the
Final Net Liabilities, the Final Aggregate Exercise Price and the amount set forth in the Adjustment Certificate. 
  

 7 

 (b) If the Stockholders Representative does not give written notice of a Dispute (a “Dispute
Notice”) within the Dispute Period to Mercury and the Escrow Agent, the determination of the Final Net Liabilities, the Final Aggregate Exercise Price and the amount set forth in the Adjustment Certificate shall be treated as if it had
been accepted and agreed to by the Stockholders Representative in the form in which it was delivered, and shall be final and binding upon the parties hereto. 
 (c) If the Stockholders Representative has a Dispute, the Stockholders Representative shall give Mercury and the Escrow Agent a Dispute Notice within the Dispute Period, setting forth the elements and amounts with
which it disagrees. Within 30 days after delivery of the Dispute Notice, Mercury and the Stockholders Representative shall attempt to resolve the Dispute and agree in writing upon the final content of the disputed Final Net Liabilities, the Final
Aggregate Exercise Price and any adjustment to be made in accordance with Section 1.8(f). 
 (d) If Mercury and the Stockholders
Representative are unable to resolve any Dispute within the 30-day period after the Stockholder Representative’s delivery of a Dispute Notice, the Stockholder Representative and Mercury shall jointly engage BDO Seidman, or if such firm declines
to act in such capacity, by such other firm of independent nationally recognized accountants having no material relationship with Mercury or Systinet and reasonably acceptable to both the Stockholder Representative and Mercury (the
“Arbitrating Accountant”) as arbitrator. In connection with the resolution of any Dispute, the Arbitrating Accountant shall have access to all documents, records, work papers, facilities and personnel necessary to perform its
function as arbitrator. The Arbitrating Accountant’s function shall be to conform the Final Net Liabilities, the Final Aggregate Exercise Price and the amount set forth in the Adjustment Certificate to the principles of preparation set forth in
this Section 1.8. The Arbitrating Accountant shall allow Mercury and the Stockholders Representative to present their respective positions regarding the Dispute. The Arbitrating Accountant may, at its discretion, conduct a conference concerning
the Dispute, at which conference each party shall have the right to present additional documents, materials and other information and to have present its advisors, counsel and accountants. In connection with such process, there shall be no hearings
or any oral examinations, testimony, depositions, discovery or other similar proceedings other than the conference referred to in the preceding sentence. The Arbitrating Accountant shall thereafter promptly render its decision on the question in
writing and finalize the Final Net Liabilities, the Final Aggregate Exercise Price and the amount set forth in the Adjustment Certificate to reflect the resolution of all Disputes. Such written determination shall be final and binding upon the
parties hereto with respect to the Dispute, and judgment may be entered on the award. The fees and expenses of the Arbitrating Accountant shall be allocated between the former holders of Systinet Capital Stock, the Cash Out Options and the Cash Out
Warrants, on the one hand, and Mercury, on the other hand, so that share of the former holders of Systinet Capital Stock, the Cash Out Options and the Cash Out Warrants of such fees and expenses shall be equal to the product of (i) and (ii),
where (i) is the aggregate amount of such fees and expenses, and where (ii) is a fraction, the numerator of which is the amount in dispute that is ultimately unsuccessfully disputed by the Stockholders Representative (as determined by the
Arbitrating Accountant), and the denominator of which is the total amount in dispute. 
  

 8 

 (e) For purposes of this Agreement, (i) the “Actual Net Liabilities” shall
be either the Estimated Net Liabilities if Mercury does not deliver the calculation contemplated by Section 1.8(a) or, if Mercury delivers such calculation, the Final Net Liabilities, and (ii) the “Aggregate Exercise
Price” shall be either the Estimated Exercise Price if Mercury does not deliver the calculation contemplated by Section 1.8(a) or, if Mercury does deliver such calculation, the Final Aggregate Exercise Price, in each case as
determined and adjusted after resolution of all Disputes in accordance with Sections 1.8(b), 1.8(c) or 1.8(d), as applicable. 
 (f) If the
Aggregate Exercise Price minus the Actual Net Liabilities (the “Actual Amount”) is greater than the Estimated Aggregate Exercise Price minus the Estimated Net Liabilities (the “Estimated Amount”), an
amount equal to difference between the Actual Amount and the Estimated Amount shall be distributed to the holders of shares of Systinet Capital Stock, vested and unexercised Systinet Options and Systinet Warrants outstanding immediately prior to the
Effective Time as contemplated by Sections 1.4 and 1.5. If the Estimated Amount is greater than the Actual Amount, an amount equal to difference between the Actual Amount and the Estimated Amount shall be distributed from the Escrow Fund to Mercury
in accordance with the Escrow Agreement. 
 ARTICLE 2 
 REPRESENTATIONS AND WARRANTIES OF SYSTINET 
 Subject to the exceptions set forth in the Disclosure
Letter of Systinet delivered concurrently with the execution of this Agreement (the “Systinet Disclosure Letter”) (which disclosures shall delineate the section or subsection to which they apply but shall also qualify such
other sections or subsections in this Article 2 to the extent it is reasonably apparent on its face from a reading of the disclosure item that such disclosure is applicable to such other section or subsection, Systinet represents and warrants to
Mercury and Merger Sub as follows: 
 2.1 Organization, Standing and Power. Each of Systinet and each of its Subsidiaries (as defined
in Section 8.4(n)) is a company duly organized, validly existing and in good standing under the laws of its jurisdiction of organization. Each of Systinet and each of its Subsidiaries has the corporate power to own its properties and to conduct
its business as now being conducted and as currently proposed by it to be conducted and is duly qualified to do business and is in good standing in each jurisdiction where the failure to be so qualified and in good standing, individually or in the
aggregate with any such other failures, could reasonably be expected to have a Material Adverse Effect (as defined in Section 8.4(i)) on Systinet. Neither Systinet nor any of its Subsidiaries is in violation of any of the provisions of its
organizational documents. Other than the Persons (as defined in Section 8.4(k)) listed on Section 2.1 of the Systinet Disclosure Letter, Systinet does not (and has not) directly or indirectly own any equity or similar interest in, or any
interest convertible or exchangeable or exercisable for, any equity or similar interest in, any Person. Section 2.1 of the Systinet Disclosure Letter sets forth a true, correct and complete list of each of its Subsidiaries indicating
(i) its officers and directors and (ii) the record and beneficial owner of all of its issued and outstanding shares of capital stock. All the outstanding capital stock of each of Systinet’s Subsidiaries is duly authorized, validly
issued, fully paid and nonassessable. There are no options, warrants, calls, rights, commitments or agreements of any character, written or oral, to which any of Systinet’s Subsidiaries is a party or by which it is bound obligating any of
Systinet’s Subsidiaries to issue, deliver, sell, repurchase or 
  

 9 

 redeem, or cause to be issued, sold, repurchased or redeemed, any shares of the capital stock of such Subsidiary or
obligating such Subsidiary to grant, extend, accelerate the vesting of, change the price of, otherwise amend or enter into any such option, warrant, call right, commitment or agreement. There are no outstanding or authorized stock appreciation,
phantom stock, profit participation, or other similar rights with respect to any of Systinet’s Subsidiaries. 
  

	2.2	Capital Structure. 

 (a) The authorized
capital stock of Systinet consists of 145,000,000 shares of Systinet Common Stock, and 82,940,000 shares of Systinet Preferred Stock. As of the date hereof there are issued and outstanding 5,056,635 shares of Common Stock, 3,640,000 shares of
Convertible Preferred Stock par value $0.01 per share (the “Convertible Preferred Stock”), 17,666,667 shares of Series A Convertible Preferred Stock par value $0.01 per share (the “Series A Preferred
Stock”), 16,562,496 shares of Series B Convertible Preferred Stock par value $0.01 per share ( the “Series B Preferred Stock”) and 43,948,741 shares of Series C Convertible Preferred Stock par
value $0.01 per share (the “Series C Preferred Stock”). Assuming (x) the Closing takes place on January 31, 2006 and (y) no additional Systinet Capital Stock is issued after the date hereof except upon
conversion of outstanding Systinet Preferred Stock and the exercise of the Systinet Options and Systinet Warrants, on a fully diluted as converted into Systinet Common Stock basis (assuming, with respect to Systinet Options, only exercise of vested
Systinet Options on such date), there would be 133,108,272 shares of Systinet Common Stock outstanding on January 31, 2006. There are not outstanding any adjustments made or required to be made to the conversion rates applicable to Systinet
Preferred Stock set forth in the Systinet Charter. Other than the accruing dividends set forth in the terms of the Systinet Preferred Stock contained in the Systinet Charter, there are no declared or accrued but unpaid dividends with respect to any
shares of Systinet Common Stock or Systinet Preferred Stock. As of the date hereof, the outstanding shares of Systinet Preferred Stock convert into the aggregate number of shares of Systinet Common Stock set forth in Section 2.2(a) of the
Systinet Disclosure Letter. Other than the shares of Systinet Capital Stock listed above, as of the date hereof, there are no other issued and outstanding shares of Systinet Capital Stock. Section 2.2(a) of the Systinet Disclosure Letter sets
forth a true, correct and complete list (with names and record addresses) of all of Systinet’s security holders, the number of shares, options, warrants or other rights to acquire shares of Systinet Capital Stock owned and any Persons with
rights to acquire Systinet securities (including all holders of outstanding Systinet Options, whether or not granted under the Systinet Option Plan, the exercise or vesting schedule, exercise price, and tax status of such options under
Section 422 of the Code). All issued and outstanding shares of Systinet Capital Stock are duly authorized, validly issued, fully paid and non-assessable and are free of preemptive rights, rights of first refusal and “put” or
“call” rights created by statute, Systinet’s organizational documents or any agreement to which Systinet is a party or by which it is bound or of which it has knowledge. Except as set forth in the Systinet Charter or in
Section 2.2(a) of the Systinet Disclosure Letter, as of the date hereof, there are no options, warrants, calls, rights, commitments or (written or oral) Contracts (as defined in Section 8.4(c)), to which Systinet is a party, or by which it
is bound, obligating Systinet to issue, deliver, sell, repurchase (other than Contracts set forth in Section 2.2(a) of the Systinet Disclosure Letter granting Systinet the right to purchase unvested shares upon termination of employment or
service) or redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any shares of any Systinet Capital Stock and/or Systinet Options or obligating Systinet to grant, extend, 
  

 10 

 accelerate the vesting and/or repurchase rights of, change the price of, or otherwise amend or enter into any such
option, warrant, call, right, commitment or agreement. Section 2.2(a) of the Systinet Disclosure Letter sets forth the number of shares of Systinet Common Stock underlying Systinet Options that will become exercisable upon consummation of the
Merger and the number of additional shares underlying Systinet Options that may become exercisable upon a change in the holder’s employment circumstances after consummation of the Merger. Except as set forth in Section 2.2(a) of the
Systinet Disclosure Letter, there are no Contracts relating to voting, purchase or sale of any Systinet Capital Stock (1) between or among Systinet and any of its security holders, other than the Systinet Options, the Systinet Warrants and
written contracts granting Systinet the right to purchase unvested shares upon termination of employment or service, and (2) to Systinet’s knowledge, between or among any of Systinet’s security holders. All outstanding Systinet
securities were issued in compliance with all applicable foreign, federal and state securities laws. 
 (b) Except for the Systinet
Corporation 2001 Stock Option and Incentive Plan (the “Systinet Option Plan”), Systinet has never adopted or maintained any stock option plan or other plan providing for equity compensation of any person. As of the date
hereof, Systinet has reserved 30,699,885 shares of Systinet Common Stock for issuance to employees and directors of, and consultants to Systinet, upon the exercise of options granted under the Systinet Option Plan, of which 26,812,847 shares are
issuable, as of the date hereof, upon the exercise of outstanding, unexercised options. As of the Effective Time, all issued and outstanding options to purchase Systinet Capital Stock shall be duly authorized by all necessary corporate action.

 (c) As of the Effective Time, none of the outstanding Systinet Common Stock will be subject to vesting, and no holder of Systinet Options
will be entitled to exercise such options before they become vested. 
 2.3 Authority; Noncontravention. (a) Systinet has all
requisite corporate power and authority to enter into this Agreement and, subject to Systinet’s receipt of the Required Vote (as defined in Section 2.18) from Systinet’s stockholders, to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and, subject to Systinet’s receipt of the Required Vote from Systinet’s stockholders, the consummation of the transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Systinet. This Agreement has been duly executed and delivered by Systinet and, assuming the due authorization, execution and delivery by Mercury and Merger Sub, constitutes the valid and binding obligation of Systinet
enforceable against Systinet in accordance with its terms, subject to the effect of (a) applicable bankruptcy, insolvency, reorganization, moratorium or similar laws now or hereafter in effect relating to rights of creditors generally and
(b) rules of law and equity governing specific performance, injunctive relief and other equitable remedies. The execution and delivery of this Agreement by Systinet does not, and the consummation of the transactions contemplated hereby will
not, (i) result in the creation of a material lien on any properties or assets of Systinet or any of its Subsidiaries or (ii) conflict with, or result in any violation of, or default under (with or without notice or lapse of time, or
both), or give rise to a right of termination, cancellation, renegotiation or acceleration of any obligation or loss of any benefit under, or require any consent, approval or waiver from any Person in accordance with, (A) any provision of the
organizational documents of Systinet or any of its Subsidiaries or (B) any material Contract, instrument, permit, judgment, order, decree, statute, law, rule or regulation 
  

 11 

 applicable to Systinet or any of its Subsidiaries or any of their respective properties or assets. Except as set forth in
Section 2.3 of the Systinet Disclosure Letter, no consent, approval, order or authorization of, or registration, declaration or filing with, any government, any court, tribunal, arbitrator, administrative agency, commission or other
governmental official, authority or instrumentality, in each case whether domestic or foreign, any stock exchange or similar self-regulatory organization or any quasi-governmental or private body exercising any regulatory, taxing or other
governmental or quasi-governmental authority (each a “Governmental Entity”) or third party is required by or with respect to Systinet or any of its Subsidiaries in connection with the execution and delivery of this Agreement
or the consummation of the transactions contemplated hereby, except for (1) the filing of the Certificate of Merger, (2) such filings as may be required under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR
Act”) or any other Antitrust Laws (as defined in Section 4.6(b)), (3) the Required Vote, or (4) such other consents, approvals, orders, authorizations, registrations, declarations or filings which if not obtained or made,
would not reasonably be expected to cause, individually or in the aggregate, a material liability for Systinet and its Subsidiaries taken as a whole. 
 (b) On the date hereof, this Agreement and the transactions contemplated hereby shall be approved by the Required Vote of the Systinet stockholders, the Systinet Stockholders Written Consent shall be delivered to the
Secretary of Systinet, and a copy of the Systinet Stockholders Written Consent shall be delivered to Mercury. 
 2.4 Financial
Statements. Except as set forth in Section 2.4 of the Systinet Disclosure Letter, Systinet has delivered to Mercury its audited consolidated financial statements as at and for the years ended December 31, 2003 and 2004 (including
balance sheets, statements of operations and statements of cash flows) (the “Audited Financial Statements”) and its unaudited consolidated financial statements as at and for the eleven-month period ended November 30,
2005 (including balance sheets, statements of operations and statements of cash flows, the “November 30 Financial Statements,” and, together with the Audited Financial Statements, the “Financial
Statements”). The Financial Statements (a) have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) (except that the unaudited financial statements do not have
notes thereto) applied on a consistent basis throughout the periods indicated, and (b) present fairly the consolidated financial condition and results of operations and cash flows of Systinet as of the dates, and for the periods, indicated
therein (subject, in the case of interim period financial statements, to normal recurring year-end audit adjustments, none of which individually or in the aggregate are material). There has been no change in Systinet accounting policies since
December 31, 2004 (the “Systinet Balance Sheet Date”), except as described in the Financial Statements. 
 2.5 Absence of Certain Changes; Undisclosed Liabilities. 
 (a) Since the Systinet Balance Sheet Date, Systinet and each of
its Subsidiaries has conducted its business only in the ordinary course of business and there has not occurred any change, event or condition (whether or not covered by insurance) that, individually or in the aggregate with any other changes, events
and conditions, has resulted in, or would reasonably be expected to result in, a Material Adverse Effect on Systinet. 
  

 12 

 (b) Neither Systinet nor any of its Subsidiaries has any indebtedness, obligations or liabilities of any
nature whether matured or unmatured, fixed or contingent (whether or not required to be reflected in the Financial Statements in accordance with GAAP) other than (i) those set forth or adequately provided for in the balance sheet as of
November 30, 2005, included in the Financial Statements (the “November 30 Balance Sheet”), (ii) those incurred in the conduct of Systinet’s business since the date of the November 30 Balance Sheet (the
“November 30 Balance Sheet Date”) in the ordinary course of business (except as disclosed in Section 2.5(b) of the Systinet Disclosure Letter), (iii) those imposed pursuant to the terms of Contracts disclosed in the
Systinet Disclosure Letter or imposed pursuant to the terms of Contracts that are not required to be disclosed in the Systinet Disclosure Letter, (iv) the Systinet Expenses (as defined in Section 4.12) and (v) those which,
individually or in the aggregate, are not material in nature or amount and would not reasonably be expected to have a Material Adverse Effect on Systinet. 
 2.6 Litigation. There is no private or governmental action, suit, proceeding, claim, arbitration or, to the knowledge of Systinet, investigation pending before any Governmental Entity or arbitrator, or, to the
knowledge of Systinet, threatened against Systinet or any of its Subsidiaries or any of their respective assets or properties, including any Systinet Intellectual Property (as defined in Section 8.4(q)), or any of their respective officers or
directors (in their capacities as such). There is no judgment, decree or order against Systinet or any of its Subsidiaries, any of their respective assets or properties, or, to the knowledge of Systinet, any of their respective directors or officers
(in their capacities as such), that could prevent, enjoin or materially alter or delay any of the transactions contemplated by this Agreement, or that, individually or in the aggregate with any such other judgments, decrees and orders, would
reasonably be expected to have a Material Adverse Effect on Systinet. 
 2.7 Restrictions on Business Activities. There is no Contract
(including covenants not to compete), judgment, injunction, order or decree binding upon Systinet or any of its Subsidiaries which has or would reasonably be expected to have, whether before or after consummation of the Merger, the effect of
prohibiting or impairing any current or future business practice of Systinet or any of its Subsidiaries, any acquisition of property (tangible or intangible) by Systinet or any of its Subsidiaries or the conduct of business by Systinet or any of its
Subsidiaries, in each case, as currently conducted or as currently proposed to be conducted by Systinet or any of its Subsidiaries. Without limiting the generality of the foregoing, neither Systinet nor any of its Subsidiaries has entered into any
agreement under which Systinet or any of its Subsidiaries is restricted from selling, licensing or otherwise distributing any of their respective technology or products to, or from providing services to, customers or potential customers or any class
of customers, in any geographic area, during any period of time or in any segment of the market.

Property or otherwise) on Systinet’s exercise of the full scope of rights afforded a joint owner or co-owner of that type of Intellectual Property right under the laws of the jurisdiction in which the Intellectual Property right exists.

and the Systinet Intellectual Property do not contain any Software code that (A) contains, or is derived in any manner (in whole or in part) from, any Software that is distributed under any of the following licenses or distribution models, or
licenses or distribution models similar to any of the following: GNU’s not Unix General Public License (GPL) or Lesser/Library GPL (LGPL); or (B) is licensed under any terms or conditions that impose any requirement that any Software

 (g) Except for the Intellectual Property licensed pursuant to the licenses set forth in
Section 2.8(d) of the Systinet Disclosure Letter and except as set forth in Section 2.8(g) of the Systinet Disclosure Letter, all Systinet Products were created solely by either (i) employees of Systinet or one of its Subsidiaries

assigned all of their rights, including Intellectual Property rights therein, to Systinet or such Subsidiary, and except as set forth in Section 2.8(b) and 2.8(d) of the Systinet Disclosure Letter, no other Person owns or has any rights to any
portion of such Systinet Products, including Intellectual Property rights therein.

any Systinet Intellectual Property to any other Person. 
 (i) The operation of the business of Systinet and each of its Subsidiaries as it
currently is conducted or is currently contemplated to be conducted by Systinet and such Subsidiary, including the design, development, use, import, manufacture and sale of Systinet Products (excluding those Systinet Products identified in
Section 2.8(i) of the Systinet Disclosure Letter), does not and will not infringe or misappropriate the Intellectual Property rights of any 
  

 15 

 Person. Neither Systinet nor any of its Subsidiaries has received any written notice from any Person claiming that such
operation or any Systinet Product (including products, technology or services currently under development) infringes or misappropriates the Intellectual Property rights of any Person or constitutes unfair competition or trade practices under the
laws of any jurisdiction (nor does Systinet have knowledge of any basis therefor). Neither Systinet nor any of its Subsidiaries has received any written offer for a license of Intellectual Property, including but not limited to Patent rights, from
any Person in connection with an allegation by such Person that Systinet or any of its Subsidiaries has infringed or misappropriated any of the Intellectual Property of such Person. Neither Systinet nor any of its Subsidiaries has received any
written opinion of counsel that any third party Patent has been, would be or is being directly or indirectly infringed by the operation of the business of Systinet and each of its Subsidiaries as previously conducted, currently conducted or

Subsidiaries is infringing or otherwise violating, and has not infringed or otherwise violated, any Intellectual Property right of any Person or any law relating to Intellectual Property. There is no pending, decided or settled opposition,
interference, reexamination, cancellation, injunction, lawsuit, proceeding, hearing investigation, complaint, arbitration, mediation, demand, decree, or any other dispute or claim related to the Systinet Intellectual Property (“IP
Dispute”), nor, to the knowledge of Systinet, has any IP Dispute been threatened, challenging the legality, validity, enforceability or ownership of any Systinet Intellectual Property. Except as set forth in Section 2.8(k) of the
Systinet Disclosure Letter, to the knowledge of Systinet, no circumstances or grounds exist that would give rise to an IP Dispute, other than immaterial disagreements with customers arising in the ordinary course of business. Neither Systinet nor
any of its Subsidiaries has sent any notice of any IP Dispute. No Systinet Intellectual Property is subject to any outstanding injunction, judgment, order, decree, ruling charge, settlement or other disposition of any IP Dispute. To the knowledge of
Systinet, no Person has infringed, misappropriated or otherwise violated any Systinet Intellectual Property. 
 (l) Except as set forth in
Section 2.8(l) of the Systinet Disclosure Letter, none of the Systinet Registered Intellectual Property has been adjudged invalid or unenforceable, in whole or in part, and Systinet has no knowledge of any facts or circumstances that would
render any Systinet Registered Intellectual Property invalid or unenforceable. Without limiting the 
  

 16 

 foregoing, Systinet has no knowledge of any information, materials, facts, or circumstances, including any information or
fact that would constitute prior art, that would render any of the Systinet Registered Intellectual Property invalid or unenforceable and neither Systinet nor any of its Subsidiaries has misrepresented, or failed to disclose, and Systinet has no
knowledge of any misrepresentation or failure to disclose, any fact or circumstance in any application for any Systinet Registered Intellectual Property that would constitute fraud or an intentional misrepresentation with respect to such application
or that would otherwise affect the validity or enforceability of any such Registered Intellectual Property. 
 (m) There are no Contracts
between Systinet or any of its Subsidiaries and any other Person with respect to Systinet Intellectual Property under which there is currently any dispute regarding the scope of such Contract, or performance under such Contract including with
respect to any payments to be made or received by Systinet or any of its Subsidiaries thereunder. 
 (n) Systinet and each of its
Subsidiaries has taken commercially reasonable steps that are required to protect Systinet’s or such Subsidiaries’ rights in Trade Secrets of Systinet or such Subsidiary, or provided by any other Person to Systinet or such Subsidiary.
Without limiting the foregoing, Systinet and each of its Subsidiaries has, and enforces, a policy requiring each employee, consultant and contractor to execute proprietary information, confidentiality and assignment agreements substantially in
Systinet’s standard forms, which forms are set forth in Section 2.8(o) of the Systinet Disclosure Letter, and all current and former employees, consultants and contractors of Systinet and each of its Subsidiaries have executed such an
agreement in substantially such corresponding standard form. 
 (o) None of the Systinet Intellectual Property owned by Systinet and, to the
knowledge of Systinet, none of the Systinet Intellectual Property licensed to Systinet was developed by or on behalf of, or using grants or any other subsidies of, any governmental entity or any university, and no government funding, facilities,
faculty or students of a university, college, other educational institution or research center or third party fee-for-service funding. No current or former employee, consultant or independent contractor of Systinet or any of its Subsidiaries, who
was involved in, or who contributed to, the creation or development of any Systinet Intellectual Property, has performed services for a government, university, college, or other educational institution or research center during a period of time
during which such employee, consultant or independent contractor was also performing services for Systinet or such Subsidiary with a result that such government, university, college or other educational institution or research center has rights in
or has placed limits on the practice or transfer of such Systinet Intellectual Property.

cause any harmful, malicious procedures, routines or mechanisms which would cause the Software to cease 
  

 17 

 functioning or to damage or corrupt data, storage media, programs, equipment or communications. Except as set forth in
Section 2.8(p) of the Systinet Disclosure Letter, none of the existing Systinet Products contains any bug, problem, flaw or similar issue that may materially adversely affect the value, functionality or fitness for the intended purposes of such
Systinet Products.
 (q) Except as set forth in Section 2.8(q) of the Systinet Disclosure Letter, none of Systinet, any of its
Subsidiaries or any other party acting on behalf of Systinet or any of its Subsidiaries has disclosed or delivered to any third party, or permitted the disclosure or delivery to any escrow agent or other party of, any Systinet Source Code (as
defined below). No event has occurred, and no circumstance or condition exists, that (with or without notice or lapse of time, or both) shall, or would reasonably be expected to, require the disclosure or delivery by Systinet, any of its
Subsidiaries or any other party acting on behalf of Systinet or any of its Subsidiaries to any third party of any Systinet Source Code. Section 2.8(q) of the Systinet Disclosure Letter identifies each Contract under which Systinet or any of its
Subsidiaries has deposited, or is or may be required to deposit, with an escrow agent or other third party, any Systinet Source Code, and describes whether the execution of this Agreement or the consummation of any of the transactions contemplated
by this Agreement, in and of itself, would reasonably be expected to result in the release of any Systinet Source Code from escrow. “Systinet Source Code” means, collectively, any human readable Software source code, or any
material portion or aspect of the Software source code, or any material proprietary information or algorithm contained in or embedded in or combined with, in any manner, any Software source code, in each case for any Systinet Product, but excluding
Open Source Material. 
 (r) Except as set forth in Section 2.8(r) of the Systinet Disclosure Letter, there are no, and the consummation
of the transactions contemplated by this Agreement will not trigger any, royalties, fees, honoraria or other payments payable by Systinet or any of its Subsidiaries to any Person by reason of the ownership, development, use, license, sale or
disposition of the Systinet Intellectual Property, including any Systinet Product, other than salaries, sales commissions and other forms of compensation paid to employees and sales agents in the ordinary course of business. 
 (s) Systinet and each of its Subsidiaries has been and is in compliance with the Export Administration Act of 1979, as amended, and all regulations
promulgated thereunder 
 (t) Systinet and each of its Subsidiaries has the right to use all Software development tools, library functions,

administrative or judicial action or proceeding or any Order beyond the earlier of (i) 90 days after the date of this Agreement and (ii) the date of a ruling preliminarily enjoining the Merger issued by a court of competent jurisdiction.
Each of Mercury and Systinet shall use commercially reasonable efforts to take such action as may be required to cause the expiration of the notice periods under the Antitrust Laws with respect to such transactions as promptly as possible after the

 4.8 Employees; Benefits. 
 (a) Employees of Systinet who remain employed by Systinet after the Merger shall receive compensation and benefits (other than stock and options) that are
in the aggregate comparable to those afforded to similarly-situated employees of Mercury, subject to the terms and conditions of the relevant benefits plans. 
 (b) To the extent that service is relevant for purposes of eligibility, vesting, calculation of any benefit, or benefit accrual under any employee benefit plan, program or arrangement established or maintained by
Mercury or the Surviving Corporation (other than any defined benefit pension plan or stock incentive plan) following the Closing Date for the benefit of Systinet Employees (or Mercury’s other employees), such plan, program or arrangement shall
credit such Systinet Employees for service on or prior to the Closing Date that was recognized by Systinet or its Subsidiaries, as the case may be, for purposes of employee benefit plans, programs or arrangements maintained by Systinet, provided
that in no event shall such crediting of service result in any duplication of benefits. In addition, with respect to any welfare benefit plan (as defined in Section 3(1) of ERISA) established or maintained by Mercury and the Surviving
Corporation following the Closing Date for the benefit of Systinet Employees (or Mercury’s other employees), such plan shall waive any pre-existing condition exclusions (to the extent that no pre-existing condition exclusion applied under a
comparable plan of Systinet prior to the Closing) and provide that any covered expenses incurred on or before the Closing Date by any Systinet Employee or by a covered dependent shall be taken into account for purposes of satisfying applicable
deductible coinsurance and maximum out-of-pocket provisions after the Closing Date. 
 (c) The individuals previously identified by Mercury
and approved by Systinet shall be terminated from their employment with Systinet on or prior to the Closing. Systinet shall use its commercially reasonable efforts to assist Mercury in obtaining a contractor agreement with each of those terminated
employees of Systinet designated by Mercury, the terms of which agreement shall be mutually acceptable to Mercury and such individual. 
 4.9 Stock Options. 
 (a) At the Effective Time, each portion of a then outstanding Systinet Option that is unvested will be
assumed by Mercury. Each portion of a Systinet Option so assumed by Mercury under this Agreement will continue to have, and be subject to, the same terms and conditions set forth in the Systinet Option Plan and the related option agreement
immediately prior to the Effective Time (including, without limitation, any repurchase rights or vesting provisions), except that (i) each such portion of a Systinet Option will be exercisable (or will become exercisable in accordance with its
terms) for that number of whole shares of the common stock of Mercury, par value $0.002 per share (“Mercury Common Stock”), equal to the product 
  

 33 

 of the number of shares of Systinet Common Stock that were issuable upon exercise of such portion of a Systinet Option
immediately prior to the Effective Time multiplied by the Exchange Ratio, rounded down to the nearest whole number of shares of Mercury Common Stock and (ii) the per share exercise price for the shares of Mercury Common Stock issuable upon
exercise of such portion of an assumed Systinet Option will be equal to the quotient determined by dividing the exercise price per share of Systinet Common Stock at which such portion of a Systinet Option was exercisable immediately prior to the
Effective Time by the Exchange Ratio, rounded up to the nearest whole cent. For purposes of this Section 4.9, “Exchange Ratio” shall mean the Systinet Price divided by the Mercury Price, rounded to six decimal places,
where the “Systinet Price” equals the Common Price Per Share, and the “Mercury Price” equals the average for the 15 trading days ended two trading days prior to the Closing Date (the
“Trailing Average Period”) of (A) for any trading day during the Trailing Average Period on which the Mercury Common Stock is listed on the National Association of Securities Dealers Automated Quotation
(“NASDAQ”) National Market System, the closing price per share of the Mercury Common Stock, or (B) for any trading day during the Trailing Average Period on which the Mercury Common Stock is not listed on the NASDAQ
National Market System, but there is a public market for the Mercury Common Stock, the mean of the closing bid and asked prices of the Mercury Common Stock, in each case as reported in the Wall Street Journal (or, if not so reported, as otherwise
reported by NASDAQ). 
 (b) It is intended that Systinet Options assumed by Mercury pursuant to Section 4.9(a) shall qualify following
the Effective Time as incentive stock options as defined in Section 422 of the Code to the extent such Systinet Options qualified as incentive stock options immediately prior to the Effective Time, and the provisions of Section 4.9(a)
shall be applied consistent with such intent. 
 (c) At the Effective Time, each portion of a then outstanding Systinet Option that is vested
(other than the Cash Out Options) will be assumed by Mercury. Each such portion of a Systinet Option so assumed by Mercury under this Agreement will continue to have, and be subject to, the same terms and conditions set forth in the Systinet Option
Plan and the related option agreement immediately prior to the Effective Time (including, without limitation, any repurchase rights or vesting provisions), except that such portion of a Systinet Option will be exercisable (or will become exercisable
in accordance with its terms) for an amount of cash equal to the product of (i) number of shares of Systinet Common Stock underlying such Systinet Option and (ii) the Common Price Per Share. 
 4.10 Form S-8. Mercury shall file a registration statement on Form S-8 for the shares of Mercury Common Stock issuable with respect to assumed
Systinet Options as soon as is reasonably practicable after the Closing and after Mercury is eligible to file a Form S-8, which Form S-8 shall include a “reoffer prospectus” (as defined in General Instruction C.1. of Form S-8) if any
person has exercised a Systinet Option before the filing of the Form S-8 contemplated by this Section 4.10 and shares have been issued upon such exercise in accordance with the terms of the Systinet Option Plan. 
 4.11 Spreadsheet. Systinet shall prepare and deliver to Mercury, at or prior to the Closing, a spreadsheet in form acceptable to Mercury and the
Exchange Agent, which spreadsheet shall be dated as of the Closing Date and shall set forth, as of the Closing Date, the 
  

 34 

 following information relating to holders of Systinet Capital Stock, Systinet Options and Systinet Warrants: (a) the
names of all Systinet stockholders, optionholders and warrant holders and their respective addresses of record, (b) the number and kind of shares of Systinet Capital Stock held by, or subject to the Systinet Options or Systinet Warrants held by
such Persons and, in the case of shares, the respective certificate numbers, (c) cash Merger Consideration (less the Escrow Fund) issuable to each holder of Systinet Capital Stock, Systinet Options and Systinet Warrants, (d) the interest
of each former holder of Systinet Capital Stock, Systinet Options or Systinet Warrants in the Escrow Fund and any amount payable pursuant to Section 1.8(f) and (e) the exercise price per share in effect for each Systinet Option and
Systinet Warrant immediately prior to the Closing Date (the “Spreadsheet”). 
 4.12 Expenses. If the Merger is
not consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby (including legal, accounting, investment banking, finders and advisory fees and expenses) shall be paid by the party
incurring such expense. If the Merger is consummated, all fees and expenses of Systinet (including legal, accounting, investment banking, finders and advisory fees and expenses) incurred in connection with this Agreement and transactions
contemplated hereby (the “Systinet Expenses”) shall be paid by the Surviving Corporation and included in the calculation of Net Liabilities. 
 4.13 Further Assurances. On the terms and subject to the conditions set forth in this Agreement, each of the parties hereto shall use commercially reasonable efforts, and shall cooperate with each other party
hereto, to take, or cause to be taken, such actions, and to do, or cause to be done, such things reasonably necessary, appropriate or desirable to consummate and make effective the Merger and the other transactions contemplated hereby, including the
satisfaction of the respective conditions set forth in Article 5. Without limiting the generality or effect of the foregoing and subject to the terms of this Agreement, in the event an injunction or other order preventing the consummation of the
Merger shall have been issued by a court of competent jurisdiction, each party hereto shall use its commercially reasonable efforts to have such injunction or other order lifted. Each party hereto, at the reasonable request of the other party
hereto, shall execute and deliver such other instruments and do and perform such other acts and things as may be reasonably necessary or reasonably desirable for effecting completely the consummation of the Merger and the other transactions
contemplated hereby. 
 4.14 Information Statement. As promptly as practicable after the date of this Agreement, Systinet shall
prepare an information statement in form and substance reasonably satisfactory to Mercury which shall include a description of the approval of the Merger Agreement, the Merger, and the transactions contemplated by the Merger Agreement and the

to review and comment on any draft of the Information Statement, and include in the Information Statement all changes reasonably proposed by 
  

 35 

 Mercury; and (iii) cause the Information Statement to be mailed to Systinet’s stockholders as promptly as
practicable following the date of this Agreement. Mercury will cooperate with Systinet in the preparation of the Information Statement and will provide all information reasonably required to be provided by it for inclusion in the Information

proposal, offer or request)) that is received by Systinet or any Affiliate or representative of Systinet. Systinet shall keep Mercury informed on a reasonably current basis (and, in any event, within 24 hours) of the status and details of any
material modifications to any such proposal, offer or request. “Acquisition Transaction” means any transaction involving: (x) the sale, license, disposition or acquisition of all or a substantial portion of the business
or assets of Systinet; (y) the issuance, disposition or acquisition of (A) any capital stock or other equity security of Systinet (other than issuances of Systinet Capital Stock upon conversion of Systinet Preferred Stock, exercise of
Systinet Options or Systinet Warrants or in routine transactions in accordance with Systinet’s past practices), (B) except as expressly contemplated by Section 4.19 of this Agreement, any option, call, warrant or right (whether or not

Systinet; in each of clauses (A) through (C), representing in the aggregate 10% or more of the voting power of Systinet; or (z) any merger, consolidation, share exchange, business combination, reorganization, recapitalization or similar

individual” (within the meaning of Section 280G of the Code), as determined immediately prior to the initiation of the procedure described in Section 4.17(b), and who would otherwise have, receive or have the right or entitlement to
receive a parachute payment from Systinet, Mercury or any ERISA Affiliate of Systinet or Mercury under Section 280G of the Code as a result of the Closing or the consummation of the Merger (including in connection with certain changes in any
such Person’s employment circumstances following the consummation of the Merger). 
 (b) Systinet shall use commercially reasonable
efforts to obtain the written consent of such a number of stockholders of Systinet as is required by the terms of Section 280G(b)(5)(B) so as to comply with the stockholder approval requirements of Section 280G of the Code with respect to
any and all payments and/or benefits provided in accordance with agreements, contracts or arrangements that, in the absence of the executed waivers described in Section 4.17(a), would be subject to such parachute payment requirements (in a
manner which satisfies all applicable requirements of such Section 280G(b)(5)(B) of the Code and the Treasury Regulations thereunder, including Q-7 of Section 1.280G-1 of such Treasury Regulations).

 (b) Governmental Approvals. Mercury and Systinet and their respective Subsidiaries shall have timely obtained from each
Governmental Entity all approvals, waivers and consents, if any, necessary for consummation of, or in connection with, the transactions contemplated hereby. Without limiting the generality of the foregoing all applicable waiting periods under any

true and correct, in each case as of the date of this Agreement and at and as of the Closing Date as if made on that date, except (i) in any case that representations and warranties that expressly speak as of a specified date or time need only
be true and correct as of such specified date or time or (ii) where the failure to be true and correct would not, in the aggregate, have a Material Adverse Effect on Mercury. Each of Mercury and Merger Sub shall have performed and complied in
all material respects with all covenants, obligations and conditions of this Agreement required to be performed and complied with by it at or prior to the Closing. 
 (b) Receipt of Closing Deliveries. Systinet shall have received each of the agreements, instruments and other documents required to have been delivered to Systinet at or prior to the Closing as set forth in

 (a) Representations, Warranties and Covenants. Each of the representations and warranties made by Systinet in this Agreement,
disregarding all materiality or Material Adverse Effect qualifications and exceptions (other than such qualifications and exceptions when used in the definition of, or to modify, the terms Systinet Products and Systinet Intellectual Property and
“Material Contract” and “Material Customers”), shall be true and correct, in each case as of the date of this Agreement and at and as of the Closing Date as if made on that date, except (i) in any case that representations
and warranties that expressly speak as of a specified date or time need only be true and correct as of such specified date or time, or (ii) where the failure to be true and correct would not, in the aggregate, have a Material Adverse Effect on
Systinet; provided, however, that such Material Adverse Effect qualifier shall be inapplicable with respect to representations and warranties contained in Section 2.2(a) and (b), each of which individually shall have been true and
correct in all respects as of the date of this Agreement and shall be true and correct in all respects on and as of the Closing Date (except in any case that representations and warranties that expressly speaks as of a specified date or time need
only be true and correct of such specified date or time). Systinet shall have performed and complied in all material respects with all covenants, obligations and conditions of this Agreement required to be performed and complied with by it at or
prior to the Closing. 
 (b) Receipt of Closing Deliveries. Mercury shall have received each of the agreements, instruments and other
documents required to have been delivered to Mercury and Merger Sub at or prior to the Closing as set forth in Exhibit F.

Injunctions or Restraints on Conduct of Business. No temporary restraining order, preliminary or permanent injunction or other order issued by any court of competent jurisdiction or other legal or regulatory restraint provision limiting or
restricting Mercury’s ownership, conduct or operation of the business of Systinet and/or any of its Subsidiaries, following the Effective Time shall be in effect, nor shall any suit, investigation, request for additional information, action or
proceeding before any Governmental Entity seeking any of the foregoing, seeking to obtain from Mercury or Systinet or any of their respective Affiliates in connection with the Merger any damages, or seeking any other relief that following the
Merger, in the sole judgment of Mercury, could reasonably be expected to materially limit or restrict the ability of the Surviving Corporation and/or its Subsidiaries to own and conduct both (i) the assets and businesses owned and conducted by
Mercury and/or its Subsidiaries prior to the Merger and (ii) the assets and businesses owned and conducted by Systinet and/or each of its Subsidiaries prior to the Merger, be pending or threatened (and in the case of any of the foregoing
initiated or sought by a non-governmental entity, threatened in writing). 
 (d) No Material Adverse Effect. There shall not have
occurred any event or condition of any character that has had or is reasonably likely to have a Material Adverse Effect on Systinet since the date of this Agreement. 
  

 39 

 (e) Section 280G Stockholder Approval. Any agreements, contracts or arrangements that, before
giving effect to any waiver described below, would result, separately or in the aggregate, in the payment of any amount or the provision of any benefit that would not be deductible by reason of Section 280G of the Code shall have been approved
by such number of stockholders of Systinet as is required by the terms of Sections 280G in order for such payments and benefits not to be deemed parachute payments under Section 280G of the Code, with such approval to be obtained in a manner
which satisfies all applicable requirements of Sections 280G(b)(5)(B) of the Code and the Treasury Regulations thereunder, including Q-7 of such Treasury Regulations, or in the absence of such stockholder approval, none of those payments or benefits
shall be paid or provided, in accordance with the waiver of those payments and benefits to be executed by the affected individuals in accordance with Section 4.17. 
 (f) Systinet Options. The holders of at least 95% of the vested and unexercised Systinet Options outstanding as of the Closing shall have agreed in writing to cancel such Systinet Options held by such Person in
exchange for the payment of cash in accordance with the provisions of Section 1.6(a).

such Systinet Options to the amendment of such holder’s Systinet Options. 
 ARTICLE 6 
 TERMINATION, AMENDMENT AND WAIVER 
 6.1 Termination. At any time prior to the Effective Time, whether before or after adoption of this Agreement by Systinet’s and Merger Sub’s stockholders, this Agreement may be terminated and the Merger and the other

 (a) by mutual written consent duly authorized by the respective boards of
directors of Mercury (or a committee thereof) (on behalf of Mercury and Merger Sub) and Systinet; 
 (b) by either Mercury or Systinet, if
the Closing shall not have occurred on or before March 31, 2006 (the “Termination Date”) provided, however, that the right to terminate this Agreement under this Section 6.1(b) shall not be available
to any party who is in material breach of this Agreement and such breach of this Agreement has resulted in the failure of the Closing to occur on or before the Termination Date; 
 (c) by either Systinet or Mercury, if any permanent injunction or other order of a court or other competent Government Entity preventing the consummation
of the transactions contemplated by this Agreement shall have become final and nonappealable; 
 (d) by Mercury, if Systinet shall have
materially breached any representation, warranty or covenant contained herein and (i) such breach shall not have been cured within thirty days after receipt by Systinet of written notice of such breach (provided, however, that no such

  

 40 

 cure period shall be available or applicable to any such breach which by its nature cannot be cured) and (ii) if not
cured at or prior to the Closing, such breach would result in the failure of any of the conditions set forth in Section 5.1 or 5.3(a) or (d) to be satisfied (provided, however, that the termination right under Section 6.1(d)
shall not be available to Mercury if Mercury is at that time in material breach of this Agreement); or 
 (e) by Systinet, if Mercury or
Merger Sub shall have materially breached any representation, warranty or covenant contained herein and (i) such breach shall not have been cured within thirty days after receipt by Mercury of written notice of such breach (provided,
however, that no such cure period shall be available or applicable to any such breach which by its nature cannot be cured) and (ii) if not cured at or prior to the Closing, such breach would result in the failure of any of the conditions
set forth in Section 5.1 or 5.2(a) to be satisfied; provided, however, that the right to terminate this Agreement under this Section 6.1(e) shall not be available to Systinet if Systinet is at that time in material breach of this
Agreement). 
 6.2 Effect of Termination. If this Agreement is terminated in accordance with Section 6.1, this Agreement shall
forthwith become void and there shall be no liability or obligation on the part of Mercury, Merger Sub or Systinet or their respective officers, directors, stockholders or Affiliates; provided, however, that each party hereto shall
remain liable for willful breaches of this Agreement prior to its termination, provided, further, that notwithstanding the foregoing proviso, Systinet shall remain liable for any breaches or inaccuracies of Sections 2.3(b), 2.17,
2.18 and 4.15 prior to the termination of this Agreement; and provided, further, that the Confidentiality Agreement and the provisions of Sections 4.12 and 6.2 and Article 8 shall remain in full force and effect and survive any
termination of this Agreement. 
 6.3 Amendment. Subject to the provisions of applicable law, the parties hereto may amend this
Agreement at any time in accordance with an instrument in writing signed on behalf of each of the parties hereto; provided, however, that an amendment made subsequent to adoption of this Agreement by the stockholders of Systinet shall not
(a) alter or change the amount or kind of consideration to be received on conversion of the Systinet Capital Stock or (b) alter or change any of the terms or conditions of this Agreement if such alteration or change would materially and
adversely affect the holders of Systinet Capital Stock. Subject to the provisions of applicable law, Mercury and the Stockholders Representative (on behalf of all of the holders of Systinet Capital Stock, vested and unexercised Systinet Options and
Systinet Warrants immediately prior to the Effective Time) may cause this Agreement to be amended at any time after the Effective Time by execution of an instrument in writing signed on behalf of Mercury and the Stockholders Representative (on
behalf of all of the holders of Systinet Capital Stock, vested and unexercised Systinet Options and Systinet Warrants immediately prior to the Effective Time); provided, however, that any amendment made in accordance with this sentence shall
not (i) alter or change the amount or kind of consideration to be received on conversion of the Systinet Capital Stock or for the vested and unexercised Systinet Options or Systinet Warrants or (ii) alter or change any of the terms or
conditions of this Agreement if such alteration or change would materially and adversely affect the stockholders of Systinet immediately prior to the Effective Time.

compliance with any of the agreements or conditions for the benefit of such party contained herein. At any time after the Effective Time, the Stockholders Representative or Mercury may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of Systinet (in the case of a waiver by Mercury) or Mercury, Merger Sub or Surviving Corporation (in the case of a waiver by the Stockholders Representative), (ii) waive any inaccuracies in
the representations and warranties made to Mercury (in the case of a waiver by Mercury) or made to Systinet (in the case of a waiver by the Stockholders Representative) herein or in any document delivered pursuant hereto and (iii) waive

of a party hereto or the Stockholders Representative to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. Without limiting the generality or effect of the preceding sentence, no
delay in exercising any right under this Agreement shall constitute a waiver of such right, and no waiver of any breach or default shall be deemed a waiver of any other breach or default of the same or any other provision in this Agreement.

 ARTICLE 7 
 ESCROW
FUND AND INDEMNIFICATION 
 7.1 Escrow Fund. The Escrow Fund shall be available to compensate Mercury and the Surviving
Corporation (on behalf of itself or any other Indemnified Person (as defined in Section 7.2)) for Losses (as defined in Section 7.2) in accordance with this Article 7. 
 7.2 Indemnification. The Escrow Fund shall be available from and after the Effective Time to indemnify and hold harmless Mercury and the Surviving
Corporation and their respective officers, directors, agents and employees, subsidiaries, directors and employees of subsidiaries, and each person, if any, who controls or may control Mercury and the Surviving Corporation within the meaning of the
Securities Act of 1933, as amended (each of the foregoing, an “Indemnified Person”) from and against any and all losses, liabilities, damages, claims, suits, settlements, royalties, costs and expenses, including costs of
investigation, settlement, and defense and reasonable legal fees, court costs, and any interest costs or penalties (collectively, “Losses”), arising out of, related to or otherwise by virtue of (a) any breach of or
inaccuracy in any representation or warranty made by Systinet in this Agreement or any other document required to be delivered to Mercury or Merger Sub in accordance with any provision of this Agreement, (b) any breach of or default in
connection with any of the covenants or agreements made by Systinet in this Agreement, (c) any appraisal or similar action with respect to shares of Systinet Capital Stock (provided, that Losses arising under this Section 7.2(c)
shall equal (i) the excess of any consideration awarded in any appraisal action over (ii) the value of the Merger Consideration allocable to the former Systinet stockholders whose shares of Systinet Capital Stock were the subject of such
appraisal action), and (d) those matters listed on Schedule 7.2(d). In determining (A) whether any representation and warranty was inaccurate or breached (except for the second sentence of Section 2.8(p)), or (B) the amount of
any Losses in respect of 
  

 42 

 any inaccuracy in or any breach of any representation and warranty, any materiality or Material Adverse Effect
qualification contained in such representation or warranty will in all respects be ignored. 
 7.3 Limitations on Indemnification;
Exclusive Remedy. 
 (a) The Indemnified Persons may not recover from the Escrow Fund in respect of any claim for indemnification in
accordance with Section 7.2(a) unless and until Losses in accordance with Section 7.2(a) have been incurred, paid or properly accrued in an aggregate amount greater than $1,000,000 (the “Indemnification Threshold”).
Notwithstanding the foregoing, the Indemnified Persons shall be entitled to recover for, and the Indemnification Threshold shall not apply as a threshold to, any Losses with respect to any breach of or inaccuracy in any representation or warranty
made by Systinet in Section 2.2 (a) or (b), Section 2.9 or Section 2.10(j) (the “Excepted Representations”). Once the Indemnification Threshold has been exceeded, the Indemnified Persons shall be entitled
to recover only Losses in excess of the Indemnification Threshold. 
 (b) No indemnification liability under this Article 7 shall attach to
any party under this Agreement in respect of any claim: 
 (i) to the extent that any provision or reserve in respect of the matter giving
rise to such claim has been provided for on the face of the November 30 Balance Sheet; 
 (ii) to the extent that the matter giving
rise to such claim resulted in an adjustment to the Merger Consideration based on the Actual Net Liabilities; 
 (iii) to the extent that
such claim relates to any Loss for which any Indemnified Person is insured and actually recovers thereunder, but only to the extent of net insurance proceeds actually recovered; and 
 (iv) to the extent that such claim relates to any Loss for which any of any Indemnified Person collects a recovery from any third party, but only to the
extent of collections actually received. 
 (c) Except for claims based on fraud, recovery from the Escrow Fund in accordance with this
Article 7 and the Escrow Agreement shall be the sole and exclusive remedy after the Effective Time for any Losses arising out of, related to or otherwise by virtue of any breach or claim in connection with this Agreement or any certificate or
writing delivered in connection with this Agreement or any transaction contemplated hereby, regardless of the cause of action; provided, however, that this Section 7.3(c) shall not limit the liability of any party for Losses arising out
of, related to or otherwise by virtue of any breach or claim in connection with the agreements described on Schedule 7.3(c). No Indemnified Person shall be entitled to make any claim directly against any former holder of Systinet Capital
Stock, vested but unexercised Systinet Options or Systinet Warrants after the Effective Time for any Losses arising out of, related to or otherwise by virtue of any breach or claim in connection with this Agreement or any certificate or writing
delivered in connection with this Agreement or any transaction contemplated hereby, regardless of the cause of action, except for (A) claims based on fraud or (B) claims directly against a former holder of Systinet Capital Stock, vested
but unexercised 
  

 43 

 Systinet Options or Systinet Warrants after the Effective Time for any Losses arising out of, related to or otherwise by
virtue of any breach or claim in connection with the agreements described on Schedule 7.3(c). In the event of fraud, no former holder of Systinet Capital Stock, vested but unexercised Systinet Options or Systinet Warrants shall be liable for any
Losses that, together with such Person’s share, based on such Person’s contribution to the Escrow Fund, of all other Losses, in the aggregate exceed the actual proceeds received by such Person with respect to its Systinet Capital Stock,
vested but unexercised Systinet Options or Systinet Warrants pursuant to Article 1, other than the Person who committed such fraud, whose liability shall not be limited. 
 (d) No holder of Systinet Capital Stock, Systinet Options or Systinet Warrants shall have any right of contribution, right of indemnity or other right or remedy against Mercury or the Surviving Corporation in
connection with any indemnification obligation or any other liability to which such holder of Systinet Capital Stock, Systinet Options or Systinet Warrants may become subject under or in connection with this Agreement. 
 7.4 Claim Period. The period during which claims for indemnification from the Escrow Fund may be initiated shall commence at the Effective Time
and terminate at the date that is eighteen months after the Effective Time (the “Claim Period”). The indemnification obligations under this Article 7 shall terminate on the date that is eighteen months after the Effective
Time, except for matters as to which an Indemnified Person has made a claim for indemnity on or before such date, which claim shall survive the expiration of such period until such claim is finally resolved in accordance with the terms of this
Article 7 and the Escrow Agreement and any obligations with respect thereto are fully satisfied. Notwithstanding anything contained in this Agreement to the contrary, at the conclusion of the Claims Period such portion of the Escrow Fund as may be
necessary in the reasonable judgment of Mercury to satisfy any unresolved or unsatisfied claims for Losses specified in any Officer’s Certificate (as defined in Section 7.5(a)) delivered to the Escrow Agent and the Stockholder
Representative prior to expiration of the Claims Period shall remain in the Escrow Fund until such claims for Losses have been resolved or satisfied provided, however, that such amount shall not exceed the aggregate amount specified in
all unresolved or unsatisfied claims for Losses specified in all such Officer’s Certificates or any Adjustment Certificate. 
 7.5
Claims upon Escrow Fund. 
 (a) Upon receipt by the Escrow Agent on or before the last day of the Claims Period of a certificate signed by
any officer of Mercury (an “Officer’s Certificate”): 
 (i) stating that an Indemnified Person has incurred,
paid or properly accrued, or reasonably anticipates that it may incur, pay or properly accrue, Losses; 
 (ii) stating the amount of such
Losses (which, in the case of Losses not yet incurred, paid or properly accrued, may be the maximum amount in good faith anticipated to be incurred, paid or properly accrued); and 
  

 44 

 (iii) specifying in reasonable detail (based upon the information then possessed by Mercury) the
individual items of such Losses included in the amount so stated and the nature of the claim to which such Losses are related; 
 subject to and in
accordance with the provisions of Sections 7.3, 7.6 and 7.7, Mercury (on behalf of itself or any other Indemnified Person) shall be entitled to receive, and the Escrow Agent shall deliver to Mercury, out of the Escrow Fund funds comprising the
Escrow Fund having a value equal to such Losses; provided, however, that, to the extent that such Losses have not then been incurred or paid by such Indemnified Person, Mercury (on behalf of itself or any other Indemnified Person) shall not
be so entitled to receive, and the Escrow Agent shall not deliver, funds in respect thereof unless and until such Losses are actually incurred or paid by such Indemnified Person. 
 7.6 Objections to Claims. At the time of delivery of any Officer’s Certificate to the Escrow Agent, a duplicate copy of such Officer’s
Certificate shall be delivered to the Stockholders Representative by or on behalf of Mercury (on behalf of itself or any other Indemnified Person) and for a period of thirty days after such delivery to the Escrow Agent of such Officer’s
Certificate, the Escrow Agent shall not release any portion of the Escrow Fund in accordance with Section 7.5 unless the Escrow Agent shall have received written authorization from the Stockholders Representative to make such delivery. After
the expiration of such thirty-day period, the Escrow Agent shall release all or a portion of the Escrow Fund in accordance with Section 7.5; provided, however, that no such payment or delivery may be made if and to the extent the
Stockholders Representative shall object in a written statement to any claim or claims made in the Officer’s Certificate, and such statement shall have been delivered to the Escrow Agent and to Mercury prior to the expiration of such thirty-day
period. 
 7.7 Resolution of Objections to Claims. 
 (a) If the Stockholders Representative shall so object in writing to any claim or claims by Mercury made in any Officer’s Certificate, Mercury shall have thirty days after its receipt of such writing to respond
in a written statement to the objection of the Stockholders Representative. If after such thirty-day period there remains a dispute as to any claims, the Stockholders Representative and Mercury shall attempt in good faith for twenty days thereafter
to agree upon the rights of the respective parties with respect to each of such claims. If an agreement is reached with respect to such claims, the Stockholders Representative and Mercury shall each execute a memorandum setting forth their
agreement, which shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and shall distribute the cash from the Escrow Fund in accordance with the terms thereof. 
 (b) If no such agreement can be reached after good faith negotiation, the Stockholders Representative and a senior representative of Mercury shall meet
within ten days of the expiration of such twenty-day period and negotiate in good faith for one day with an impartial mediator in San Francisco, California. If an agreement is reached through mediation, the Stockholders Representative and Mercury
shall each execute a memorandum setting forth their agreement, which shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and shall distribute the cash from the Escrow Fund in accordance with the
terms thereof. The mediator shall be an individual mutually agreed to by Mercury and the Stockholders Representative. 
  

 45 

 (c) If no agreement can be reached after good faith mediation, the arbitration provisions of
Section 8.11 shall be followed and the decision of the arbitrator regarding such claim shall be binding and conclusive upon the parties to this Agreement; provided, however, that any dispute or claim regarding Section 2.8 or in
connection with any Systinet Intellectual Property, shall not be subject to the arbitration provisions of Section 8.11 and in lieu thereof such disputes shall be resolved as provided in Section 8.12. The Escrow Agent shall be entitled to
act in accordance with the decision of such Arbitrator, or in the case that Section 8.12 applies, in accordance with the final non-appealable decision of the court, and make or withhold payments out of the Escrow Fund in accordance therewith.

 7.8 Third-Party Claims. If Mercury becomes aware of a third-party claim which Mercury believes may result in a claim by or on
behalf of an Indemnified Person, Mercury shall promptly notify the Stockholders Representative of such third-party claim, and provide the Stockholders Representative the opportunity to participate at its own cost in any defense of such claim.
Mercury shall have the right in its sole discretion to settle any such claim; provided, however, that without the written consent of the Stockholders Representative, no settlement of any such claim with third-party claimants shall be
determinative of the amount of Losses relating to such matter; and further provided, however, that, except for amounts satisfied in full from the Escrow Fund, no Indemnified Party shall have the right or authority to settle any such claim
with third-party claimants if such settlement would subject any former holder of Systinet Capital Stock, vested but unexercised Systinet Options or Systinet Warrants (excluding any individual who is a then-current or former employee of Mercury or
any of its Subsidiaries, but only in his or her capacity as an employee) to any monetary or non-monetary relief or any criminal or quasi-criminal sanctions, penalties or fines or admit that any former holder of Systinet Capital Stock, vested but
unexercised Systinet Options or Systinet Warrants has any liability or responsibility for such claim without the written consent of such holder. If the Stockholders Representative consents to any such settlement referred to in the first proviso of
the preceding sentence, neither the Stockholders Representative nor current or former holder of Systinet Capital Stock, vested but unexercised Systinet Options or Systinet Warrants immediately prior to the Effective Time shall have any power or
authority to object to the amount or validity of any claim by or on behalf of any Indemnified Person for indemnity with respect to such settlement. Notwithstanding any other provision of this Agreement, any Losses incurred or suffered by the
Indemnified Persons, directly or indirectly, as a result of such claim, shall constitute Losses subject to indemnities under Section 7.2. 
 7.9 Stockholders Representative. 
 (a) At the Effective Time, Warburg Pincus Private Equity VIII, L.P. shall be constituted
and appointed as the Stockholders Representative. The Stockholders Representative shall be the exclusive agent for and on behalf of the current or former holder of Systinet Capital Stock, vested but unexercised Systinet Options or Systinet Warrants
immediately prior to the Effective Time to: (i) give and receive notices and communications to or from Mercury (on behalf of itself or any other Indemnified Person) and/or the Escrow Agent relating to this Agreement, the Escrow Agreement or any
of the transactions and other matters contemplated 
  

 46 

 hereby or thereby; (ii) authorize deliveries to Mercury of cash from the Escrow Fund in satisfaction of claims
asserted by Mercury (on behalf of itself or any other Indemnified Person, including by not objecting to such claims); (iii) object to such claims in accordance with Section 7.6; (iv) consent or agree to, negotiate, enter into
settlements and compromises of, and demand mediation and arbitration and comply with orders of courts and awards of arbitrators with respect to, such claims; and (v) take all actions necessary or appropriate in the judgment of the Stockholders
Representative for the accomplishment of the foregoing, in each case without having to seek or obtain the consent of any Person under any circumstance. The Stockholders Representative shall be the sole and exclusive means of asserting or addressing
any of the above and no current or former holder of Systinet Capital Stock, vested but unexercised Systinet Options or Systinet Warrants immediately prior to the Effective Time shall have any right to act on its own behalf with respect to any such
matters, other than any claim or dispute against the Stockholders Representative. The Person serving as the Stockholders Representative may be replaced from time to time by the holders of a majority in interest of the shares or other property then
on deposit in the Escrow Fund upon not less than ten days’ prior written notice to Mercury. No bond shall be required of the Stockholders Representative, and the Stockholders Representative shall receive no compensation for his services.
Notices or communications to or from the Stockholders Representative shall constitute notice to or from each of the holders of Systinet Capital Stock, Systinet Options and Systinet Warrants immediately prior to the Effective Time. 
 (b) The Stockholders Representative shall not be liable to any holder of Systinet Capital Stock, Systinet Options or Systinet Warrants immediately prior
to the Effective Time for any act done or omitted hereunder as the Stockholders Representative while acting in good faith and any act done or omitted in accordance with the advice of counsel or other expert shall be conclusive evidence of such good
faith. The holders of Systinet Capital Stock, Systinet Options or Systinet Warrants immediately prior to the Effective Time shall severally indemnify the Stockholders Representative and hold it harmless against any loss, liability or expense
incurred without gross negligence or bad faith on the part of the Stockholders Representative and arising out of or in connection with the acceptance or administration of its duties hereunder. 
 (c) The Stockholders Representative shall have reasonable access to information about Systinet and the reasonable assistance of Systinet’s former
officers and employees for purposes of performing his duties and exercising its rights hereunder, provided that the Stockholders Representative shall treat confidentially and not disclose any nonpublic information from or about Systinet to
anyone (except on a need to know basis to individuals who agree to treat such information confidentially). 
 7.10 Actions of the
Stockholders Representative. Any notice or communication given or received by, and any decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, the Stockholders
Representative that is within the scope of the Stockholders Representative’s authority under Section 7.7(a) shall constitute a notice or communication to or by, or a decision, action, failure to act within a designated period of time,
agreement, consent, settlement, resolution or instruction of all holders of Systinet Capital Stock, Systinet Options and Systinet Warrants immediately prior to the Effective Time and shall be final, binding and conclusive upon each such holder; and
each Indemnified Person and the Escrow Agent shall be entitled to rely upon any such notice, 
  

 47 

 communication, decision, action, failure to act within a designated period of time, agreement, consent, settlement,
resolution or instruction as being a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, each and every such holder. Except for
their gross negligence and willful misconduct, each Indemnified Person and the Escrow Agent are unconditionally and irrevocably relieved from any liability to any person for any acts done by them in accordance with any such notice, communication,
decision, action, failure to act within a designated period of time, agreement, consent or instruction of the Stockholders Representative. 
 7.11 Purchase Price Adjustment. All indemnification payments made under this Agreement shall be treated as adjustments to the Merger Consideration to the extent permitted under applicable law. 
 ARTICLE 8 
 GENERAL PROVISIONS

other document required to be delivered in accordance with any provision of this Agreement shall survive the Effective Time and remain in full force and effect until the date that is eighteen months after the Effective Time; provided,
however, that the representations and warranties concerning outstanding Systinet Capital Stock, options, warrants and other securities set forth in Section 2.2(a) and (b) shall survive the Effective Time and remain in full force and
effect indefinitely; provided, further, that no right to indemnification in accordance with Article 7 in respect of any claim based upon any breach of or inaccuracy in a representation or warranty that is set forth in an Officer’s
Certificate delivered to the Escrow Agent prior to the expiration of the Claims Period shall be affected by the expiration of such representations and warranties as applied to such claim. The representations and warranties made by Mercury in this
Agreement or in any other documents required to be delivered to Systinet in accordance with any provision of this Agreement shall terminate at the Effective Time. Nothing in this Section 8.1 or any other provision of this Agreement shall be
construed to limit the survival of any covenant or agreement of the Mercury, Merger Sub, Systinet or the Surviving Corporation contained in this Agreement or any of the ancillary agreements, which shall survive the Merger and continue for the time
periods set forth therein (or, if no time period is set forth therein, for the applicable statute of limitations), other than covenants and agreements of Mercury, Merger Sub or Systinet which by their terms are to be wholly performed prior to the
Effective Time.

	Name:	 	Cary DavisSystinet Corporation 2001 Stock Option and Incentive Plan

 Exhibit 10.35 
 Systinet Corporation 
 2001 Stock Option and Incentive Plan 
 1. Purpose and Eligibility 
 The purpose of this 2001 Stock
Option and Incentive Plan (the “Plan”) of Systinet Corporation (the “Company”) is to provide stock options and other equity interests in the Company (each an “Award”) to employees, officers, directors, consultants and
advisors of the Company and its Subsidiaries, all of whom are eligible to receive Awards under the Plan. Any person to whom an Award has been granted under the Plan is called a “Participant”. Additional definitions are contained in
Section 8. 
 2. Administration 
 a.
Administration by Board of Directors. The Plan will be administered by the Board of Directors of the Company (the “Board”). The Board, in its sole discretion, shall have the authority to grant and amend Awards, to adopt, amend and repeal
rules relating to the Plan and to interpret and correct the provisions of the Plan and any Award. All decisions by the Board shall be final and binding on all interested persons. Neither the Company nor any member of the Board shall be liable for
any action or determination relating to the Plan. 
 b. Appointment of Committees. To the extent permitted by applicable law, the Board may
delegate any or all of its powers under the Plan to one or more committees or subcommittees of the Board (a “Committee”). All references in the Plan to the “Board” shall mean such Committee or the Board. 
 c. Delegation to Executive Officers. To the extent permitted by applicable law, the Board may delegate to one or more executive officers of the Company
the power to grant Awards and exercise such other powers under the Plan as the Board may determine, provided that the Board shall fix the maximum number of Awards to be granted and the maximum number of shares issuable to any one Participant
pursuant to Awards granted by such executive officers. 
 3. Stock Available for Awards 
 a. Number of Shares. Subject to adjustment under Section 3(c), the aggregate number of shares of Common Stock of the Company (the “Common
Stock”) that may be issued pursuant to the Plan is 42,800,000 shares. If any Award expires, or is terminated, surrendered or forfeited, in whole or in part, the unissued Common Stock covered by such Award shall again be available for the grant
of Awards under the Plan. If shares of Common Stock issued pursuant to the Plan are repurchased by, or are surrendered or forfeited to, the Company at no more than cost, such shares of Common Stock shall again be available for the grant of Awards
under the Plan; provided, however, that the cumulative number of 

 such shares that may be so reissued under the Plan will not exceed 42,800,000 shares. Shares issued under the Plan may
consist in whole or in part of authorized but unissued shares or treasury shares. 
 b. Per-Participant Limit. Subject to adjustment under
Section 3(c), no Participant may be granted Awards during any one fiscal year to purchase more than 2,000,000 shares of Common Stock. 
 c.
Adjustment to Common Stock. In the event of any stock split, stock dividend, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off, split-up, or other similar
change in capitalization or event, (i) the number and class of securities available for Awards under the Plan and the per-Participant share limit, (ii) the number and class of securities, vesting schedule and exercise price per share
subject to each outstanding Option, (iii) the repurchase price per security subject to repurchase, and (iv) the terms of each other outstanding stock-based Award shall be adjusted by the Company (or substituted Awards may be made) to the
extent the Board shall determine, in good faith, that such an adjustment (or substitution) is appropriate. If Section 7(e)(i) applies for any event, this Section 3(c) shall not be applicable. 
 4. Stock Options 
 a. General. The Board may grant options to
purchase Common Stock (each, an “Option”) and determine the number of shares of Common Stock to be covered by each Option, the exercise price of each Option and the conditions and limitations applicable to the exercise of each Option and
the Common Stock issued upon the exercise of each Option, including vesting provisions, repurchase provisions and restrictions relating to applicable federal or state securities laws, as it considers advisable. 
 b. Incentive Stock Options. An Option that the Board intends to be an “incentive stock option” as defined in Section 422 of the Code (an
“Incentive Stock Option”) shall be granted only to employees of the Company and shall be subject to and shall be construed consistently with the requirements of Section 422 of the Code. The Board and the Company shall have no
liability if an Option or any part thereof that is intended to be an Incentive Stock Option does not qualify as such. An Option or any part thereof that does not qualify as an Incentive Stock Option is referred to herein as a “Nonstatutory
Stock Option.” 
 c. Exercise Price. The Board shall establish the exercise price (or determine the method by which the exercise price
shall be determined) at the time each Option is granted and specify it in the applicable option agreement. 
 d. Duration of Options. Each
Option shall be exercisable at such times and subject to such terms and conditions as the Board may specify in the applicable option agreement. 

 e. Exercise of Option. Options may be exercised only by delivery to the Company of a written notice of
exercise signed by the proper person together with payment in full as specified in Section 4(f) for the number of shares for which the Option is exercised. 
 f. Payment Upon Exercise. Common Stock purchased upon the exercise of an Option shall be paid for by one or any combination of the following forms of payment: 
 (i) by check payable to the order of the Company; 
 (ii) except as otherwise explicitly provided in the applicable option agreement, and only if the Common Stock is then publicly traded, delivery of an irrevocable and unconditional undertaking by a creditworthy broker to deliver promptly to
the Company sufficient funds to pay the exercise price, or delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a creditworthy broker to deliver promptly to the Company cash or a check sufficient to
pay the exercise price; or 
 (iii) to the extent explicitly provided in the applicable option agreement, by (x) delivery of shares of
Common Stock owned by the Participant valued at fair market value (as determined by the Board or as determined pursuant to the applicable option agreement), (y) delivery of a promissory note of the Participant to the Company (and delivery to
the Company by the Participant of a check in an amount equal to the par value of the shares purchased), or (z) payment of such other lawful consideration as the Board may determine. 
 5. Restricted Stock 
 a. Grants. The Board may grant Awards entitling recipients to acquire shares of Common
Stock, subject to (i) delivery to the Company by the Participant of a check in an amount at least equal to the par value of the shares purchased, and (ii) the right of the Company to repurchase all or part of such shares at their issue
price or other stated or formula price from the Participant in the event that conditions specified by the Board in the applicable Award are not satisfied prior to the end of the applicable restriction period or periods established by the Board for
such Award (each, a “Restricted Stock Award”). 
 b. Terms and Conditions. The Board shall determine the terms and conditions of
any such Restricted Stock Award. Any stock certificates issued in respect of a Restricted Stock Award shall be registered in the name of the Participant and, unless otherwise determined by the Board, deposited by the Participant, together with a
stock power endorsed in blank, with the Company (or its designee). After the expiration of the applicable restriction periods, the Company (or such designee) shall deliver the certificates no longer subject to 

 such restrictions to the Participant or, if the Participant has died, to the beneficiary designated by a Participant, in
a manner determined by the Board, to receive amounts due or exercise rights of the Participant in the event of the Participant’s death (the “Designated Beneficiary”). In the absence of an effective designation by a Participant,
Designated Beneficiary shall mean the Participant’s estate. 
 6. Other Stock-Based Awards 
 The Board shall have the right to grant other Awards based upon the Common Stock having such terms and conditions as the Board may determine, including,
without limitation, the grant of shares based upon certain conditions, the grant of securities convertible into Common Stock and the grant of stock appreciation rights, phantom stock awards or stock units. 
 7. General Provisions Applicable to Awards 
 a.
Transferability of Awards. Except as the Board may otherwise determine or provide in an Award, Awards shall not be sold, assigned, transferred, pledged or otherwise encumbered by the person to whom they are granted, either voluntarily or by
operation of law, except by will or the laws of descent and distribution, and, during the life of the Participant, shall be exercisable only by the Participant. References to a Participant, to the extent relevant in the context, shall include
references to authorized transferees. 
 b. Documentation. Each Award under the Plan shall be evidenced by a written instrument in such form
as the Board shall determine or as executed by an officer of the Company pursuant to authority delegated by the Board. Each Award may contain terms and conditions in addition to those set forth in the Plan provided that such terms and conditions do
not contravene the provisions of the Plan. 
 c. Board Discretion. The terms of each type of Award need not be identical, and the Board need
not treat Participants uniformly. d. Termination of Status. The Board shall determine the effect on an Award of the disability, death, retirement, authorized leave of absence or other change in the employment or other status of a Participant and the
extent to which, and the period during which, the Participant, or the Participant’s legal representative, conservator, guardian or Designated Beneficiary, may exercise rights under the Award. 
 e. Acquisition of the Company 
 (i)
Consequences of an Acquisition. 
 (A) Disposition of Awards. Unless otherwise expressly provided in the applicable Option or Award, upon the
occurrence of an 

 Acquisition the Board or the board of directors of the surviving or acquiring entity (as used in this
Section 7(e)(i)(A), also the “Board”), shall, as to outstanding Awards (on the same basis or on different bases, as the Board shall specify): 
 (1) make appropriate provision for the continuation of such Awards by the Company or the assumption of such Awards by the surviving or acquiring entity and by substituting on an equitable basis for the shares then
subject to such Awards either (a) the consideration payable with respect to the outstanding shares of Common Stock in connection with the Acquisition, (b) shares of stock of the surviving or acquiring corporation or (c) such other
securities as the Board deems appropriate, the fair market value of which (as determined by the Board in its sole discretion) shall not materially differ from the fair market value of the shares of Common Stock subject to such Awards immediately
preceding the Acquisition; 
 (2) upon written notice to the affected optionees, provide that all Options then outstanding shall become fully exercisable and
must be exercised within a specified number of days of the date of such notice, at the end of which period such Options shall terminate; or 
 (3) upon
written notice to the affected optionees, provide that all Options then outstanding shall be terminated in exchange for a cash payment equal to the excess of the fair market value (as determined by the Board in its sole discretion) of the shares
subject to such Options over the exercise price thereof. 
 (B) Acquisition Defined. “Acquisition” means: (x) a merger,
consolidation or other reorganization of the outstanding voting securities of the Company in which the holders of the outstanding voting securities of the Company immediately prior to the consummation of such event, shall, immediately following such
event, hold, as a group, less than a majority of the outstanding voting securities of the surviving or successor entity; (y) an acquisition (other than by merger or consolidation) of more than 50% of the outstanding voting securities of the
Company in one or a series of related transactions by any person or group that beneficially owned less than 20% of the voting securities of the Company prior to such acquisition; or (z) a sale, lease, transfer or other disposition (other than
by merger or consolidation) of all or substantially all of the assets of the Company (other than in a spin-off or similar transaction to the Company’s existing voting securityholders). 
 (ii) Assumption of Options Upon Certain Events. In connection with a merger or consolidation of an entity with the Company or the acquisition by the
Company of property or stock of an entity, the Board may grant Awards under the Plan in substitution for stock and stock-based awards issued by such entity or an affiliate thereof. The substitute Awards shall be granted on such terms and conditions
as the Board considers appropriate in the circumstances. 

 (iii) Pooling-of Interests-Accounting. If the Company proposes to engage in an Acquisition intended to be
accounted for as a pooling-of-interests, and in the event that the provisions of this Plan or of any Award hereunder, or any actions of the Board taken in connection with such Acquisition, are determined by the Company’s or the acquiring
company’s independent public accountants to cause such Acquisition to fail to be accounted for as a pooling-of-interests, then such provisions or actions shall be amended or rescinded by the Board, without the consent of any Participant, to be
consistent with pooling-of-interests accounting treatment for such Acquisition. 
 (iv) Parachute Awards. If, in connection with an
Acquisition, a tax under Section 4999 of the Code would be imposed on the Participant (after taking into account the exceptions set forth in Sections 280G(b)(4) and 280G(b)(5) of the Code), then the number of Awards which shall become
exercisable, realizable or vested as provided in such section shall be reduced (or delayed), to the minimum extent necessary, so that no such tax would be imposed on the Participant (the Awards not becoming so accelerated, realizable or vested, the
“Parachute Awards”). 
 f. Withholding. Each Participant shall pay to the Company, or make provisions satisfactory to the Company
for payment of, any taxes required by law to be withheld in connection with Awards to such Participant no later than the date of the event creating the tax liability. The Board may allow Participants to satisfy such tax obligations in whole or in
part by transferring shares of Common Stock, including shares retained from the Award creating the tax obligation, valued at their fair market value (as determined by the Board or as determined pursuant to the applicable option agreement). The
Company may, to the extent permitted by law, deduct any such tax obligations from any payment of any kind otherwise due to a Participant. 
 g. Amendment of Awards. The Board may amend, modify or terminate any outstanding Award including, but not limited to, substituting therefor another Award of the same or a different type, changing the date of exercise or realization, and
converting an Incentive Stock Option to a Nonstatutory Stock Option, provided that, except as otherwise provided in Section 7(e)(iii), the Participant’s consent to such action shall be required unless the Board determines that the action,
taking into account any related action, would not materially and adversely affect the Participant. 
 h. Conditions on Delivery of Stock. The
Company will not be obligated to deliver any shares of Common Stock pursuant to the Plan or to remove restrictions from shares previously delivered under the Plan until (i) all conditions of the Award have been met or removed to the
satisfaction of the Company, (ii) in the opinion of the Company’s counsel, all other legal matters in connection with the issuance and delivery of such shares have been satisfied, including any applicable securities laws and any applicable
stock exchange or stock market rules and regulations, and (iii) the Participant has executed and 

 delivered to the Company such representations or agreements as the Company may consider appropriate to satisfy the
requirements of any applicable laws, rules or regulations. 
 i. Acceleration. The Board may at any time provide that any Options shall
become immediately exercisable in full or in part, that any Restricted Stock Awards shall be free of some or all restrictions, or that any other stock-based Awards may become exercisable in full or in part or free of some or all restrictions or
conditions, or otherwise realizable in full or in part, as the case may be, despite the fact that the foregoing actions may (i) cause the application of Sections 280G and 4999 of the Code if a change in control of the Company occurs, or
(ii) disqualify all or part of the Option as an Incentive Stock Option. In the event of the acceleration of the exercisability of one or more outstanding Options, the Board may provide, as a condition of full exercisability or any or all such
Options, that the Common Stock as to which exercisability has been accelerated shall be restricted stock subject to forfeiture and repurchase at the option of the Company at the cost thereof upon termination of employment or other relationship, with
the timing and other terms of the vesting of such restricted stock being equivalent to the timing and other terms of the superseded exercise schedule of the related Option. 
 8. Miscellaneous 
 a. Definitions. 
 (i) “Company,” for purposes of eligibility under the Plan, shall include any present or future subsidiary corporations of Systinet Corporation,
as defined in Section 424(f) of the Code (a “Subsidiary”), and any present or future parent corporation of Systinet Corporation, as defined in Section 424(e) of the Code. For purposes of Awards other than Incentive Stock Options,
the term “Company” shall include any other business venture in which the Company has a direct or indirect significant interest, as determined by the Board in its sole discretion. 
 (ii) “Code” means the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder. 
 (iii) “employee” for purposes of eligibility under the Plan (but not for purposes of Section 4(b)) shall include a person to whom an offer
of employment has been extended by the Company. 
 b. No Right To Employment or Other Status. No person shall have any claim or right to be
granted an Award, and the grant of an Award shall not be construed as giving a Participant the right to continued employment or any other relationship with the Company. The Company expressly reserves the right at any time to dismiss or otherwise
terminate its relationship with a Participant free from any liability or claim under the Plan. 

 c. No Rights As Stockholder. Subject to the provisions of the applicable Award, no Participant or
Designated Beneficiary shall have any rights as a stockholder with respect to any shares of Common Stock to be distributed with respect to an Award until becoming the record holder thereof. 
 d. Effective Date and Term of Plan. The Plan shall become effective on the date on which it is adopted by the Board. No Awards shall be granted under the
Plan after the completion of ten years from the date on which the Plan was adopted by the Board, but Awards previously granted may extend beyond that date. 
 e. Amendment of Plan. The Board may amend, suspend or terminate the Plan or any portion thereof at any time. 
 f. Governing Law. The provisions of the Plan and all Awards made hereunder shall be governed by and interpreted in accordance with the laws of the Commonwealth of Massachusetts, without regard to any applicable conflicts of law.
