THIS ESCROW AGREEMENT (as the same may be amended or modified from time to time and including any and all written instructions given to “Escrow Agent” (hereinafter defined) pursuant hereto, this “Escrow Agreement”) is made and entered into as of September 20, 2007, by and  among Perficient, Inc., a Delaware corporation (“Party A”), Kent Kasica as Representative of the holders (each a “Stockholder” and collectively, the “Stockholders”) of shares of common stock, par value $0.001 per share, of Perficient, Inc. (“Parent Common Stock”) set forth on Annex I hereto (“Party B,” and together with Party A, sometimes referred to collectively as the “Parties”), and JPMorgan Chase Bank, N.A. (the “Escrow Agent”).

WHEREAS, Party A and Party B are parties to that certain Agreement and Plan of Merger dated as of September 20, 2007 (the “Merger Agreement”).  Escrow Agent is not a party to, has not received and will not be responsible for the Merger Agreement.

WHEREAS, in connection with the closing of the transactions contemplated by the Merger Agreement (the “Closing”), the Stockholders have agreed to deposit into escrow with the Escrow Agent one or more certificates in the name of the Stockholders evidencing in the aggregate 53,961 shares of Parent Common Stock (such shares referred to herein as the “Escrowed Shares”) and the sum of $1,873,800 (the “Escrowed Cash” and together with the Escrowed Shares, the “Escrowed Deposit”) , to be held by the Escrow Agent pursuant to the terms and conditions set forth in this Agreement and the Merger Agreement pending the occurrence of certain events set forth herein and therein; and

WHEREAS, the purpose of the Escrowed Deposit is to secure claims under Article IX of the Merger Agreement (“Indemnification Claims”); and

WHEREAS, Escrow Agent is willing to serve in such capacity on the terms and conditions hereinafter set forth.

NOW THEREFORE, in consideration of the foregoing and of the mutual covenants hereinafter set forth, the parties hereto agree as follows:

1.           Appointment.  The Parties hereby appoint the Escrow Agent as their escrow agent for the purposes set forth herein, and the Escrow Agent hereby accepts such appointment under the terms and conditions set forth herein.

2.           Definitions.  Unless otherwise defined herein, each capitalized term used in this Agreement shall have the meaning ascribed to such term in the Merger Agreement.

3.           Authority of Party A.  Each of the Parties hereto agrees that Party A shall have authority to settle all Indemnification Claims in accordance with Article IX of the Merger Agreement on behalf of any of the affiliates of Party A.  Unless the context otherwise requires, any references to Party A contained herein shall be deemed to be references to Parent and its affiliates.

4.           Authority of Party B.  Prior to the distribution of the Escrowed Deposit, if any, each of the Parties hereto agree that Party B shall have authority to settle all claims under this Agreement or the Merger Agreement on behalf of any Stockholder who is entitled to receive a part of the Escrowed Deposit, if any, upon the release and distribution from this escrow.

5.           Deposit of Escrowed Shares and Investment of Escrowed Cash.

(a)           Promptly following the date of this Escrow Agreement, Party A shall instruct Continental Stock Transfer & Trust Company (“Continental”) to deliver the Escrowed Shares and any stock powers received by Continental in connection with the Escrowed Shares to the Escrow Agent and Party A shall deliver the Escrowed

Cash to the Escrow Agent.  The Escrowed Deposit shall constitute an escrow account (the “Escrow Account”) for the satisfaction of Indemnification Claims of the Parent Indemnified Persons under the Merger Agreement.  The Escrow Account shall not be subject to any lien, attachment, trustee process or any other judicial process of any creditor of any person, including any Party hereto.  The Escrow Agent agrees to accept delivery of the Escrowed Shares, the stock powers and the Escrowed Cash, and to hold the Escrowed Shares, the stock powers and the Escrowed Cash in an escrow account, subject to the terms and conditions of this Escrow Agreement.

(b)           Each record owner of the Escrowed Shares shall be entitled to exercise all voting rights with respect to such owner’s Escrowed Shares.

(c)           Party A and Party B agree between themselves, for the benefit of Party A and the Escrow Agent, that any securities or other property distributable (whether by way of dividend, stock split or otherwise) in respect of or in exchange for any Escrowed Shares shall not be distributed to the record owners of such Escrowed Shares, but rather shall be distributed to and held by the Escrow Agent in the Escrow Account.  Ordinary cash dividends will be paid by Party A directly to the Stockholders or other record owners of such Escrowed Shares and not to the Escrow Agent.  Unless and until the Escrow Agent shall actually receive such additional securities or other property, it may assume without inquiry that the Escrowed Shares and Escrowed Cash currently being held by it in the Escrow Account are all that the Escrow Agent is required to hold.  At the time any Escrowed Shares or Escrowed Cash are required to be released from the Escrow Account to any Person pursuant to this Agreement, any securities or other property previously received by the Escrow Agent in respect of or in exchange for such Escrowed Shares or Escrowed Cash shall be released from the Escrow Account to such Person.

(d)           During the term of this Escrow Agreement, the Escrowed Cash may be invested by the Escrow Agent in (a) a JPMorgan Chase Bank, N.A. money market account, (b) a trust account with JPMorgan Chase Bank, N.A. or (c) a money market mutual fund (separately specified in writing), including without limitation a JPMorgan fund or any other mutual fund for which the Escrow Agent or any affiliate of the Escrow Agent serves as investment manager, administrator, shareholder servicing agent and/or custodian or subcustodian, notwithstanding that (i) the Escrow Agent or an affiliate of the Escrow Agent receives fees from such funds for services rendered, (ii) the Escrow Agent charges and collects fees for services rendered pursuant to this Escrow Agreement, which fees are separate from the fees received from such funds, and (iii) services performed for such funds and pursuant to this Escrow Agreement may at times duplicate those provided to such funds by the Escrow Agent or its affiliates; or such other investments as shall be directed in writing by the Parties and as shall be acceptable to the Escrow Agent.  Such written instructions, if any, referred to in the foregoing sentence shall specify the type and identity of the investments to be purchased and/or sold and will be executed through JPMorgan Asset Management (“JPMAM”), in the investment management division of JPMorgan Chase.  Unless otherwise instructed in writing by the Parties, Escrow Agent shall invest the Escrow Fund in selection (b) above.

Subject to principles of best execution, transactions shall be effected on behalf of the Escrowed Deposit through broker-dealers selected by JPMAM.  In this regard, JPMAM seeks to attain the best overall result for the Escrow Fund, taking into consideration quality of service and reliability.  An agency fee will be assessed in connection with each transaction. The Escrow Agent shall have the right to liquidate any investments held in order to provide funds necessary to make required payments under this Escrow Agreement.  The Escrow Agent shall have no liability for any loss sustained as a result of any investment in an investment made pursuant to the terms of this contract or as a result of any liquidation of any investment prior to its maturity or for the failure of the parties to give the Escrow Agent instructions to invest or reinvest the Escrowed Deposit.  The Escrow Agent or any of its affiliates may receive compensation with respect to any investment directed hereunder.  Receipt, investment and reinvestment of the Escrowed Deposit shall be confirmed by Escrow Agent as soon as practicable by account statement, and any discrepancies in any such account statement shall be noted by parties to Escrow Agent within 30 calendar days after receipt thereof.  Failure to inform Escrow Agent in writing of any discrepancies in any such account statement within said 30-day period shall conclusively be deemed confirmation of such account statement in its entirety.

6.           Release Date.  For purposes of this Agreement, the “Release Date” shall be September 20, 2008.

7.           Administration of Escrow Account.  Except as otherwise provided herein, the Escrow Agent shall administer the Escrow Account as follows:

2

(a)           If, as of the Release Date, the Escrow Agent has not received written notice of any Indemnification Claims, then the Escrow Account, less the amount of all Claimed Amounts that have not been paid or otherwise resolved as of the Release Date (the “Retained Amount”) shall promptly (and in any event no later than 10 Business Days thereafter) be released to the Stockholders in whose names they have been issued as detailed in a written notice from Party B detailing the delivery instructions.  Upon resolution of all Claim Notices made prior to the Release Date, that portion of the Retained Amount that is not paid to Party A in satisfaction of such Claim Notices shall immediately be disbursed to the Stockholders as set forth in Party B’s delivery instructions delivered as of the Release Date.

(b)           Subject to the terms and conditions set forth in Section 9.04 of the Merger Agreement, if, at any time prior to 5:00 p.m. Central Time on September 20, 2008, Party A desires to make a claim against the Escrow Account with respect to any Indemnification Claim, then Party A shall, on or prior 5:00 p.m. Central Time on September 20, 2008, deliver a written claim notice (a “Claim Notice”) to Party B and to the Escrow Agent.  Such Claim Notice shall contain (i) a description and a good faith estimate of the amount of any Damages incurred or reasonably expected to be incurred by Party A (the “Claimed Amount”); (ii) a statement that Party A is entitled to indemnification under Article IX of the Merger Agreement for such Damages; and (iii) a demand for payment.  The number of Escrowed Shares, if any, to be released shall be determined in accordance with Section7(d) below.

(c)           Prior to 5:00 p.m. Central Time on the 30th day after receipt by Escrow Agent of a Claim Notice, Party B may deliver to Party A and to the Escrow Agent a written response (the “Response Notice”) in which Party B may:  (i) agree that the full Claimed Amount may be released from the Escrow Account to Party A; (ii) agree that part, but not all, of the Claimed Amount (the “Agreed Amount”) may be released from the Escrow Account to Party A; or (iii) indicate that no part of the Claimed Amount may be released from the Escrow Account to Party A.  Any part of the Claimed Amount that is not to be released to Party A shall be the “Contested Amount.”

(A)           If Party B does not deliver a Response Notice within such 30-day period, then Party B shall be deemed to have indicated that the entire Claimed Amount may be released from Escrow Account to Party A.

(B)           If Party B delivers a Response Notice agreeing that the full Claimed Amount may be released from the Escrow Account to Party A, the Escrow Agent shall promptly following the receipt of the Response Notice, deliver to Party A such Claimed Amount.

(C)           If Party B delivers a Response Notice agreeing that part, but not all, of the Claimed Amount may be released from the Escrow Account to Party A, the Escrow Agent shall promptly following the receipt of the Response Notice deliver to Party A such Agreed Amount.

(D)           If Party B delivers a Response Notice indicating that there is a Contested Amount, Party B and Party A shall attempt in good faith to resolve the dispute related to the Contested Amount.  If Party A and Party B shall resolve such dispute, such resolution shall be binding on Party B and Party A and any other Parent Indemnified Person and Securityholder Indemnitee, as applicable, and a settlement agreement shall be signed by Party A and Party B and sent to the Escrow Agent, who shall, upon receipt thereof, if applicable, release Escrowed Shares and Escrowed Cash from the Escrow Account in accordance with the specific instructions provided in such agreement, subject to Section 7(e).

(E)           If Party B and Party A are unable to resolve the dispute relating to any Contested Amount within 45 days after the delivery of the Claim Notice, the settlement of such Contested Amount shall take place by a binding arbitration proceeding which shall take place in Austin, Texas, unless an alternative location is otherwise mutually agreed to by Party A and Party B, and be conducted by an arbitrator who has not been affiliated with or engaged by either party for a period of five years preceding the commencement of the arbitration proceeding, and the Escrow Agent shall continue to hold the Contested Amount until Escrow Agent receives either:  (i) a written notice signed by Party A and Party B, providing specific written instructions regarding the delivery of the Contested Amount, if any, to be released from the Escrow Account; or (ii) a final arbitration decision, in accordance with the following procedures, providing specific written instructions regarding the delivery of any or all

3

of such Contested Amount.  The Contested Amount shall be settled in accordance with the Expedited Procedures of the Commercial Arbitration Rules of the American Arbitration Association.  The arbitrator's decision shall relate solely to whether Party A is entitled to receive the Contested Amount (or a portion thereof) from the Escrow Account pursuant to the applicable terms of the Merger Agreement and this Escrow Agreement.  The final decision of the arbitrator shall be furnished to Party A, Party B and the Escrow Agent in writing and shall constitute the conclusive determination of the issue in question, be binding upon Party A, the Stockholders and the Escrow Agent.  The prevailing party in any arbitration (which determination shall be made by the arbitrator) shall be entitled to an award of attorneys’ fees and costs to be paid by the losing party (which determination shall be made by the arbitrator), and the losing party shall also be liable for all costs of arbitration, including, but not limited to, the compensation to be paid to the arbitrator in any proceeding and the transcript and other expenses of such proceeding.

(d)           Any amounts distributed to Party A from the Escrow Account shall be satisfied pro rata from each Stockholder’s Escrowed Deposit in accordance with each Stockholder’s Percentage Interest set forth on Annex I to this Escrow Agreement.  Any such Claimed Amount, Agreed Amount, portion of the Contested Amount which may be awarded to Party A or other award, as applicable, to be released to Party A by the Escrow Agent shall be done on the basis of 60% of any such amount from Escrowed Cash and 40% of any such amount from Escrowed Shares (such number of Escrowed Shares to be determined in accordance with Section 7(e)).

(e)           The number of Escrowed Shares, if any, to be released in payment and settlement of any Claimed Amount, Agreed Amount or all or any portion of the Contested Amount which may be awarded to Party A pursuant to Section 7(d) above shall be determined by dividing 40% of such Claimed Amount, Agreed Amount or award, as applicable, by the average closing sale price per share of Buyer Common Stock as reported on the Nasdaq Global Select Market for the 30 consecutive trading days ending on the date that is one trading day immediately preceding the closing date of the Merger Agreement (as adjusted as appropriate to reflect any stock splits, stock dividends, combinations, reorganizations, reclassifications or similar events).  The Escrow Agent will not be responsible for determining the share price.

8.           Escrow Agent.  The Escrow Agent undertakes to perform only such duties as are expressly set forth herein and no duties shall be implied. The Escrow Agent shall have no liability under and no duty to inquire as to the provisions of any agreement other than this Escrow Agreement.  The Escrow Agent may rely upon any written notice, document, instruction or request furnished to it hereunder and believed by it to be genuine and to have been signed or presented by the proper party or parties.  The Escrow Agent shall be under no duty to inquire into or investigate the validity, accuracy or content of any such document, notice, instruction or request.  The Escrow Agent shall have no duty to solicit any payments which may be due it or the Escrow Account.  The Escrow Agent shall not be liable for any action taken or omitted by it in good faith except to the extent that a final adjudication of a court of competent jurisdiction determines that the Escrow Agent's gross negligence or willful misconduct was the primary cause of any loss to either of the Parties.  The Escrow Agent may execute any of its powers and perform any of its duties hereunder directly or through agents or attorneys (and shall be liable only for the careful selection of any such agent or attorney) and may consult with counsel, accountants and other skilled persons to be selected and retained by it.  The Escrow Agent shall not be liable for anything done, suffered or omitted in good faith by it in accordance with the advice or opinion of any such counsel, accountants or other skilled persons except to the extent that a final adjudication of a court of competent jurisdiction determines that the Escrow Agent's gross negligence or willful misconduct was the primary cause of any loss to either of the Parties.  In the event that the Escrow Agent shall be uncertain as to its duties or rights hereunder or shall receive instructions, claims or demands from any party hereto which, in its opinion, conflict with any of the provisions of this Escrow Agreement, it shall be entitled to refrain from taking any action and its sole obligation shall be to keep safely all property held in escrow until it shall be directed otherwise in writing by all of the other parties hereto or by a final order or judgment of a court of competent jurisdiction.  The Escrow Agent may interplead all of the assets held hereunder into a court of competent jurisdiction or may seek a declaratory judgment with respect to certain circumstances, and thereafter be fully relieved from any and all liability or obligation with respect to such interpleaded assets or any action or nonaction based on such declaratory judgment.  The parties hereto other than the Escrow Agent agree to pursue any redress or recourse in connection with any dispute without making the Escrow Agent a party to the same.  Anything in this Escrow Agreement to the contrary notwithstanding, in no event shall the Escrow Agent be liable for special, indirect or consequential loss or damage of any kind whatsoever (including but not limited to lost profits), even if the Escrow Agent has been advised of the likelihood of such loss or damage and

4

 regardless of the form of action.Escrow Agent may rely on the validity, accuracy and content of the statements contained any written notice, document, instruction, or request furnished to it hereunder by Party A and Party B without further investigation, inquiry or examination.  For the avoidance of doubt, the Escrow Agent shall have no liability with respect to any provisions of this Escrow Agreement which set forth obligations or limitations of liability that the other parties to this Escrow Agreement have to each other.  The Escrow Agent shall have no obligation to investigate, inquire, examine or assist in any manner whatsoever, the parties' compliance with the terms of this Escrow Agreement that incorporate by reference provisions of the Merger Agreement that apply to the other parties' obligations or limitations of liability to each other that do not relate to obligations of the Escrow Agent under this Escrow Agreement.

9.           Succession.  The Escrow Agent may resign and be discharged from its duties or obligations hereunder by giving its written resignation to the Parties.  Such resignation shall take effect on the earlier of (a) a successor escrow agent being in place and (b) 30 days after such resignation is given to the Parties.  In such event, Party A may appoint a successor escrow agent.  If Party A fails to appoint a successor escrow agent within 15 days after receiving the Escrow Agent’s written resignation, the Escrow Agent shall have the right to apply to a court of competent jurisdiction for the appointment of a successor escrow agent.  The successor escrow agent shall execute and deliver to the Escrow Agent an instrument accepting such appointment and the successor escrow agent shall, without further acts, be vested with all the estates, property rights, powers and duties of the predecessor Escrow Agent as if originally names as Escrow Agent herein.  The Escrow Agent shall act in accordance with written instructions from Party A and Party B as to the transfer of the Escrow Account to a successor escrow agent.  If Party A fails to appoint a successor escrow agent prior to the expiration of 30 days following receipt of the notice of resignation, the Escrow Agent may petition any court of competent jurisdiction for the appointment of a successor escrow agent or for other appropriate relief, and any such resulting appointment shall be binding upon all of the parties hereto.

10.         Removal of Escrow Agent.  The Escrow Agent may be removed at any time by mutual agreement of Party A and Party B by giving not less than 30 days’ prior written notice to the Escrow Agent.  Prior to the expiration of such 30-day period, Party A and Party B shall designate, by mutual consent, a successor escrow agent.  If no successor escrow agent is appointed within such 30-day period, the Escrow Agent may deposit the amounts remaining in the Escrow Account with a court of competent jurisdiction located in Austin, Texas, whereupon the Escrow Agent shall be discharged of all duties and obligations hereunder.

11.         Compensation andReimbursement.  Party A agrees to (a) pay the Escrow Agent upon execution of this Escrow Agreement and from time to time thereafter reasonable compensation for the services to be rendered hereunder, which unless otherwise agreed in writing shall be as described in Annex III attached hereto, and (b) pay or reimburse the Escrow Agent upon request for all expenses, disbursements and advances, including reasonable attorney's fees and expenses, incurred or made by it in connection with the preparation, execution, performance, delivery, modification and termination of this Escrow Agreement.
