| 5.     | VACATION. In   accordance with the attached U.S. Executive and Sales Vacation Policy,   Employee will not accrue vacation time, but will be eligible to take as much   or as little time off as is consistent with the performance of the duties of   his/her position. It is assumed that Employee will prioritize client and   company business needs when planning vacation time.

| 11.    | TERM/TERMINATION.   Employee’s employment under this Agreement shall be at-will and may be   terminated with or without cause by either party upon 14 days’ (two-week)   written notice. This at-will employment relationship is the full and final   agreement regarding the nature of employment with the company, it supersedes   all existing policies and practices, and it may not be amended or waived   except in a written document signed by the Vice President of Human Resources   of Inforte. No other employee, including any officer, manager or supervisor,   has authority to enter into any agreement with Employee for employment for a   specified period of time or to make any agreement for employment other than   at-will.                                                                                                                                                                                                                                           |

|   | If Employee   is in violation of this Agreement, Employer may terminate employment without   notice and with compensation to Employee only to the date of such   termination. Inforte and Employee further agree that in the event that   Employee breaches the two-week notice provision contained in this Agreement,   it would be impracticable or extremely difficult to fix the actual damages   resulting from said breach. Therefore, should Employee breach the notice   provision, Employee agrees to pay, as liquidated damages and not as a   penalty, the sum of Five Thousand Dollars ($5,000.00) to Inforte, which sum represents   a reasonable endeavor by Inforte and Employee to estimate fair compensation   for the foreseeable losses that might result from such breach. Inforte and   Employee further agree that in any action Inforte brings to recover such   liquidated damages, it [or the prevailing party] will be entitled to recover   its attorneys’ fees, ifany. |

This Agreement contains the entire agreement of the parties and   there are no other promises or conditions in any other agreement whether   written or oral. This Agreement supersedes any prior written or oral   agreements between the parties. |
|                                                                                                                           |   |

If any provisions of this Agreement shall be held to be invalid or   unenforceable for any reason, the remaining provisions shall continue to be   valid and enforceable. If a court finds that any provision of this Agreement   is invalid or unenforceable, but that by limiting such provision it would   become valid or enforceable, then such provision shall be deemed to be   written, construed and enforced as so limited. |

The failure of either party to enforce any provision of   this Agreement shall not be construed as a waiver or limitation of that   party’s right to subsequently enforce and compel strict compliance with every   provision of this Agreement. |
|                                                                                                                           |   |
