Provided that Inforte exercises the Inforte   Third Call, effective as of the date of this Agreement, Inforte shall have   the option (the “Inforte Fourth Call” and, with the Inforte First Call,   Inforte Second Call and Inforte Third Call, collectively, the “Inforte Calls”)   to purchase a whole number of Units (the “Inforte Fourth Call Units”)   from PKI that is sufficient to increase Inforte’s percentage interest of   outstanding Units to fifty-one percent (51%) of all outstanding Units on a   fully diluted basis. The exercise price for the Inforte Fourth Call shall be   One Million Dollars ($1,000,000.00) (the “Inforte Fourth Call Price”).   Inforte may exercise the Inforte Fourth Call by giving notice (the “Inforte   Fourth Call Notice”) in writing to PKI within thetime periods set forth   in Section 12.5 below (as may be extended), stating its intention to exercise   such call. The day on which the Inforte Fourth Call Notice is given is the “Inforte   Fourth Call Notice Date.” Within thirty (30) business days from the   Inforte Fourth Call Notice Date, unless a later date is agreed to by the   parties, PKI shall sell, and Inforte shall purchase, the Inforte  Fourth Call Units, free and clear of all   security interests, liens and encumbrances. Simultaneous with the conveyance   of the Inforte Fourth Call Units, Inforte shall pay to PKI the Inforte Fourth   Call Price. Such payment shall be made by wire transfer, or such other form   as Inforte and PKI mutually agree. Inforte shall not exercise the Inforte   Fourth Call prior to exercise of the Inforte Third Call (and all prior calls)   but may exercise both (or all prior) calls simultaneously. Upon the   completion of the transfer of the Inforte Fourth Call Units permitted by this   Section12.4, PKI shall be deemed to have transferred to Inforte an amount of   its Unreturned Capital and Capital Account equal to the purchase price paid   by Inforte.                                                                                                                                                                     |

|   |           Section   12.5 Termination of the Inforte Calls. The Inforte First Call may be   exercised until November 21, 2005 (the “Inforte First Call Termination Date”).   Provided that Inforte exercises the Inforte First Call, the Inforte Second   Call may be exercised until February 20, 2006 (the “Inforte Second Call   Termination Date”). Provided that Inforte exercises the Inforte Second   Call, the Inforte Third Call may be exercised until April 20, 2006 (the “Inforte   Third Call Termination Date”). Provided that Inforte exercises the   Inforte Third Call, the Inforte Fourth Call may be exercised until August 21,   2006 (the “ Inforte Fourth Call Termination Date” and, with the   Inforte First Call Termination Date, the Inforte Second Call Termination   Date, the Inforte Third Call Termination Date, collectively, the “InforteCall Termination Dates”). Anything in this Agreement to the contrary   notwithstanding, to the extent that any Inforte Call Termination Date   otherwise would expire on or before twenty (20) business days prior to the   final resolution of the Matter, such Inforte Call Termination Date shall be   deemed extended for all purposes under this Agreement without prejudice to   any rights of Inforte under this Agreement to the date that is twenty (20)   business days following written notice by PKI to Inforte of such final   resolution; provided, however, no Inforte Call Termination Date shall be   extended beyond December 31, 2006. For purposes of this Section 12.5, “Matter”   shall mean the dispute described in the arbitration proceeding commenced in   2005 between PKI and another party to the PRTLA. Within five (5) business   days following final resolution of the Matter, PKI shall provide Inforte with   written notice thereof, including in such notice all information sufficient  for the Board of Directors of Inforte, in its reasonable judgment, to assess   the impact of such  final resolution   on the business of the Company; provided, however, the obligation of PKI to   disclose information in the notice is qualified by any contractual   confidentiality obligation of PKI to any third party. |

The PKI Call shall   expire on the date (the “PKI Call Termination Date”) that is twenty   (20) business days after the Inforte Fourth Call Termination Date as such   Inforte Fourth Call Termination Date may be extended pursuant to Section   12.5. The exercise price of the PKI Call (the “PKI Call Price”) shall   be the sum of (i) to the extent paid by Inforte, the Inforte First Call   Price, the Inforte Second Call Price, the Inforte Third Call Price and the   Inforte Fourth Call Price plus (ii) the greater of Two Million Dollars($2,000,000.00) or the amount of Inforte’s Capital Account balance at the   time the full PKI Call Price is tendered. |
