      3.3 The Lender is hereby specifically authorized, after the Maturity Date
(defined in the Notes) accelerated or otherwise, or after an Event of Default
(as defined herein) and the expiration of any applicable cure period, to
transfer any Collateral into the name of the Lender and to take any and all
action deemed advisable to the Lender to remove any transfer restrictions
affecting the Collateral.

4. Perfection of Security Interest.

      4.1 Debtor shall prepare, execute and deliver to the Lender UCC-1
Financing Statements. The Lender is instructed to prepare and file at Debtor's
cost and expense, financing statements in such jurisdictions deemed advisable to
the Lender, including but not limited to Delaware. The Financing Statements are
deemed to have been filed for the benefit of the Lender.

      4.2 All other certificates and instruments constituting Collateral from
time to time required to be pledged to Lender pursuant to the terms hereof (the
"Additional Collateral") shall be delivered to Lender promptly upon receipt
thereof by or on behalf of any of Debtor. All such certificates and instruments
shall be held by or on behalf of Lender pursuant hereto and shall be delivered
in suitable form for transfer by delivery, or shall be accompanied by duly
executed instruments of transfer or assignment or undated stock powers executed
in blank, all in form and substance satisfactory to Lender. If any Collateral
consists of uncertificated securities, unless the immediately following sentence
is applicable thereto, Debtor shall cause Lender (or its custodian, nominee or
other designee) to become the registered holder thereof, or cause each issuer of
such securities to agree that it will comply with instructions originated by
Lender with respect to such securities without further consent by Debtor. If any
Collateral consists of security entitlements, Debtor shall transfer such
security entitlements to Lender (or its custodian, nominee or other designee) or
cause the applicable securities intermediary to agree that it will comply with
entitlement orders by Lender without further consent by Debtor.

      4.3 Within five (5) days after the receipt by Debtor of any Additional
Collateral, a Pledge Amendment, duly executed by Debtor, in substantially the
form of Annex I hereto (a "Pledge Amendment"), shall be delivered to Lender in
respect of the Additional Collateral to be pledged pursuant to this Agreement.
Debtor hereby authorizes Lender to attach each Pledge Amendment to this
Agreement and agrees that all certificates or instruments listed on any Pledge
Amendment delivered to Lender shall for all purposes hereunder constitute
Collateral.

                                       3
<PAGE>

      4.4 If Debtor shall receive, by virtue of Debtor's being or having been an
owner of any Collateral, any (i) stock certificate (including, without
limitation, any certificate representing a stock dividend or distribution in
connection with any increase or reduction of capital, reclassification, merger,
consolidation, sale of assets, combination of shares, stock split, spin-off or
split-off), promissory note or other instrument, (ii) option or right, whether
as an addition to, substitution for, or in exchange for, any Collateral, or
otherwise, (iii) dividends payable in cash (except such dividends permitted to
be retained by Debtor pursuant to Section 5.2 hereof) or in securities or other
property or (iv) dividends or other distributions in connection with a partial
or total liquidation or dissolution or in connection with a reduction of
capital, capital surplus or paid-in surplus, Debtor shall receive such stock
certificate, promissory note, instrument, option, right, payment or distribution
in trust for the benefit of Lender, shall segregate it from Debtor's other
property and shall deliver it forthwith to Lender, in the exact form received,
with any necessary endorsement and/or appropriate stock powers duly executed in
blank, to be held by Lender as Collateral and as further collateral security for
the Obligations.

      4.5 Upon satisfaction in full of the Secured Notes, the Lender will
authorize the Company to file UCC termination statements in each jurisdiction in
which it filed UCC Financing Statements.

5. Distribution on Liquidation.

      5.1 If any sum is paid as a liquidating distribution on or with respect to
the Collateral, Debtor shall deliver same to the Lender to be applied to the
Obligations, then due, in accordance with the terms of the Convertible Notes.

      5.2 So long as no Event of Default exists, Debtor shall be entitled (i) to
exercise all voting power pertaining to any of the Collateral, provided such
exercise is not contrary to the interests of the Lender and does not impair the
Collateral and (ii) may receive and retain any and all dividends, interest
payments or other distributions paid in respect of the Collateral.

            5.3. Upon the occurrence and during the continuation of an Event of
Default, all rights of Debtor, upon notice given by Lender, to exercise the
voting power and receive payments, which it would otherwise be entitled to
pursuant to Section 5.2, shall cease and all such rights shall thereupon become
vested in Lender, which shall thereupon have the sole right to exercise such
voting power and receive such payments.

      5.4 All dividends, distributions, interest and other payments which are
received by Debtor contrary to the provisions of Section 5.3 shall be received
in trust for the benefit of Lender, shall be segregated from other funds of
Debtor, and shall be forthwith paid over to Lender as Collateral in the exact
form received with any necessary endorsement and/or appropriate stock powers
duly executed in blank, to be held by Lender as Collateral and as further
collateral security for the Obligations.

6. Further Action By Debtor; Covenants and Warranties.

      6.1 Debtor has and will continue to have full title to the Collateral free
from any liens, leases, encumbrances, judgments or other claims. Lender's
security interest in the Collateral constitutes and will continue to constitute
a first, prior and indefeasible security interest in favor of Lender. Debtor
will do all acts and things, and will execute and file all instruments
(including, but not limited to, security agreements, financing statements,
continuation statements, etc.) reasonably requested by Lender to establish,
maintain and continue the perfected security interest of Lender in the
Collateral, and will promptly on demand, pay all costs and expenses of filing
and recording, including the costs of any searches reasonably deemed necessary
by Lender from time to time to establish and determine the validity and the
continuing priority of the security interest of Lender, and also pay all other
claims and charges that, in the opinion of Lender, exercised in good faith, are
reasonably likely to materially prejudice, imperil or otherwise affect the
Collateral or Lender's security interests therein.

      6.2 Other than in the ordinary course of business, and except for
Collateral which is substituted by assets of identical or greater value or which
has become obsolete or is of inconsequential value, Debtor will not sell,
transfer, assign or pledge those items of Collateral (or allow any such items to
be sold, transferred, assigned or pledged), without the prior written consent of
Lender other than a transfer of the Collateral to a wholly-owned subsidiary on
prior notice to Lender, and provided the Collateral remains subject to the
security interest herein described. Although Proceeds of Collateral are covered
by this Agreement, this shall not be construed to mean that Lender consents to
any sale of the Collateral, except as provided herein. Sales of Collateral in
the ordinary course of business shall be free of the security interest of Lender
and Lender shall promptly execute such documents (including without limitation
releases and termination statements) as may be required by Debtor to evidence or
effectuate the same.

      6.3 Debtor will, at all reasonable times and upon reasonable notice, allow
Lender or its representatives free and complete access to the Collateral and all
of Debtor's records which in any way relate to the Collateral, for such
inspection and examination as Lender reasonably deems necessary.

      6.4 Debtor, at its sole cost and expense, will protect and defend this
Security Agreement, all of the rights of Lender hereunder, and the Collateral
against the claims and demands of all other persons.

      6.5 Debtor will promptly notify Lender of any levy, distraint or other
seizure by legal process or otherwise of any part of the Collateral, and of any
threatened or filed claims or proceedings that are reasonably likely to affect
or impair any of the rights of Lender under this Security Agreement in any
material respect.

      6.6 Debtor, at its own expense, will obtain and maintain in force
insurance policies covering losses or damage to those items of Collateral which
constitute physical personal property. The insurance policies to be obtained by
Debtor shall be in form and amounts reasonably acceptable to Lender. Debtor
shall make the Lender first a loss payee thereon to the extent of its interest
in the Collateral. Lender is hereby irrevocably (until the Obligations are paid
in full) appointed Debtor's attorney-in-fact to endorse any check or draft that
may be payable to Debtor so that Lender may collect the proceeds payable for any
loss under such insurance. The proceeds of such insurance (subject to the rights
of senior secured parties), less any costs and expenses incurred or paid by
Lender in the collection thereof, shall be applied either toward the cost of the
repair or replacement of the items damaged or destroyed, or on account of any
sums secured hereby, whether or not then due or payable.

      6.7 Lender may, at its option, and without any obligation to do so, pay,
perform and discharge any and all amounts, costs, expenses and liabilities
herein agreed to be paid or performed by Debtor. Upon Debtor's failure to do so,
all amounts expended by Lender in so doing shall become part of the Obligations
secured hereby, and shall be immediately due and payable by Debtor to Lender
upon demand and shall bear interest at the lesser of 15% per annum or the
highest legal amount from the dates of such expenditures until paid.

      6.8 Upon the request of Lender, Debtor will furnish to Lender within five
(5) business days thereafter, or to any proposed assignee of this Security
Agreement, a written statement in form reasonably satisfactory to Lender, duly
acknowledged, certifying the amount of the principal and interest and any other
sum then owing under the Obligations, whether to its knowledge any claims,
offsets or defenses exist against the Obligations or against this Security
Agreement, or any of the terms and provisions of any other agreement of Debtor
securing the Obligations. In connection with any assignment by Lender of this
Security Agreement, Debtor hereby agrees to cause the insurance policies
required hereby to be carried by Debtor, if any, to be endorsed in form
satisfactory to Lender or to such assignee, with loss payable clauses in favor
of such assignee, and to cause such endorsements to be delivered to Lender
within ten (10) calendar days after request therefor by Lender.

                                       5
<PAGE>

      6.9 Debtor will, at its own expense, make, execute, endorse, acknowledge,
file and/or deliver to the Lender from time to time such vouchers, invoices,
schedules, confirmatory assignments, conveyances, financing statements, transfer
endorsements, powers of attorney, certificates, reports and other reasonable
assurances or instruments and take further steps relating to the Collateral and
other property or rights covered by the security interest hereby granted, as the
Lender may reasonably require to perfect its security interest hereunder.

      6.10 Debtor represents and warrants that it is the true and lawful
exclusive owner of the Collateral, free and clear of any liens and encumbrances.

      6.11 Debtor hereby agrees not to divest itself of any right under the
Collateral except as permitted herein absent prior written approval of the
Lender, except to a subsidiary organized and located in the United States on
prior notice to Lender provided the Collateral remains subject to the security
interest herein described.

7. Power of Attorney.

      After the occurrence and during the uncured continuation of an Event of
Default as defined in Section 9 below, Debtor hereby irrevocably constitutes and
appoints the Lender as the true and lawful attorney of Debtor, with full power
of substitution, in the place and stead of Debtor and in the name of Debtor or
otherwise, at any time or times, in the discretion of the Lender, to take any
action and to execute any instrument or document which the Lender may deem
necessary or advisable to accomplish the purposes of this Agreement. This power
of attorney is coupled with an interest and is irrevocable until the Obligations
are satisfied.

8. Performance By The Lender.

      If Debtor fails to perform any material covenant, agreement, duty or
obligation of Debtor under this Agreement, the Lender may, after any applicable
cure period, at any time or times in its discretion, take action to effect
performance of such obligation. All reasonable expenses of the Lender incurred
in connection with the foregoing authorization shall be payable by Debtor as
provided in Paragraph 12.1 hereof. No discretionary right, remedy or power
granted to the Lender under any part of this Agreement shall be deemed to impose
any obligation whatsoever on the Lender with respect thereto, such rights,
remedies and powers being solely for the protection of the Lender.

9. Event of Default.

      An event of default ("Event of Default") shall be deemed to have occurred
hereunder upon the occurrence of any event of default as defined and described
in this Agreement, in the Notes, Subscription Agreement, and any other agreement
to which Debtor and Lender are parties. Upon and after any Event of Default,
after the applicable cure period, if any, any or all of the Obligations shall
become immediately due and payable at the option of the Lender, and the Lender
may dispose of Collateral as provided below. A default by Debtor of any of its
material obligations pursuant to this Agreement shall be an Event of Default
hereunder and an event of default as defined in the Notes, and Subscription
Agreement.

                                       6
<PAGE>

10. Disposition of Collateral.

      Upon and after any Event of Default which is then continuing,

      10.1 The Lender may exercise its rights with respect to each and every
component of the Collateral, without regard to the existence of any other
security or source of payment for the Obligations. In addition to other rights
and remedies provided for herein or otherwise available to it, the Lender shall
have all of the rights and remedies of a lender on default under the Uniform
Commercial Code then in effect in the State of New York.

      10.2 If any notice to Debtor of the sale or other disposition of
Collateral is required by then applicable law, five business (5) days prior
written notice (which Debtor agrees is reasonable notice within the meaning of
Section 9-612(a) of the Uniform Commercial Code) shall be given to Debtor of the
time and place of any sale of Collateral which Debtor hereby agrees may be by
private sale. The rights granted in this Section are in addition to any and all
rights available to Lender under the Uniform Commercial Code.

      10.3 The Lender is authorized, at any such sale, if the Lender deems it
advisable to do so, in order to comply with any applicable securities laws, to
restrict the prospective bidders or purchasers to persons who will represent and
agree, among other things, that they are purchasing the Collateral for their own
account for investment, and not with a view to the distribution or resale
thereof, or otherwise to restrict such sale in such other manner as the Lender
deems advisable to ensure such compliance. Sales made subject to such
restrictions shall be deemed to have been made in a commercially reasonable
manner.

      10.4 All proceeds received by the Lender in respect of any sale,
collection or other enforcement or disposition of Collateral, shall be applied
(after deduction of any amounts payable to the Lender pursuant to Paragraph 12.1
hereof) against the Obligations. Upon payment in full of all Obligations, Debtor
shall be entitled to the return of all Collateral, including cash, which has not
been used or applied toward the payment of Obligations or used or applied to any
and all costs or expenses of the Lender incurred in connection with the
liquidation of the Collateral (unless another person is legally entitled
thereto). Any assignment of Collateral by the Lender to Debtor shall be without
representation or warranty of any nature whatsoever and wholly without recourse.
To the extent allowed by law, Lender may purchase the Collateral and pay for
such purchase by offsetting up to the proceeds with sums owed to Lender by
Debtor arising under the Obligations or any other source.

      11. Waiver of Automatic Stay. Debtor acknowledges and agrees that should a
proceeding under any bankruptcy or insolvency law be commenced by or against
Debtor, or if any of the Collateral should become the subject of any bankruptcy
or insolvency proceeding, then the Lender should be entitled to, among other
relief to which the Lender may be entitled under the Note, Subscription
Agreement and any other agreement to which the Debtor, or Lender are parties,
(collectively "Loan Documents") and/or applicable law, an order from the court
granting immediate relief from the automatic stay pursuant to 11 U.S.C. Section
362 to permit the Lender to exercise all of its rights and remedies pursuant to
the Loan Documents and/or applicable law. Debtor EXPRESSLY WAIVES THE BENEFIT OF
THE AUTOMATIC STAY IMPOSED BY 11 U.S.C. SECTION 362. FURTHERMORE, Debtor
EXPRESSLY ACKNOWLEDGES AND AGREES THAT NEITHER 11 U.S.C. SECTION 362 NOR ANY
OTHER SECTION OF THE BANKRUPTCY CODE OR OTHER STATUTE OR RULE (INCLUDING,
WITHOUT LIMITATION, 11 U.S.C. SECTION 105) SHALL STAY, INTERDICT, CONDITION,
REDUCE OR INHIBIT IN ANY WAY THE ABILITY OF THE LENDER TO ENFORCE ANY OF ITS
RIGHTS AND REMEDIES UNDER THE LOAN DOCUMENTS AND/OR APPLICABLE LAW. Debtor
hereby consents to any motion for relief from stay which may be filed by the
Lender in any bankruptcy or insolvency proceeding initiated by or against
Debtor, and further agrees not to file any opposition to any motion for relief
from stay filed by the Lender. Debtor represents, acknowledges and agrees that
this provision is a specific and material aspect of this Agreement, and that the
Lender would not agree to the terms of this Agreement if this waiver were not a
part of this Agreement. Debtor further represents, acknowledges and agrees that
this waiver is knowingly, intelligently and voluntarily made, that neither the
Lender nor any person acting on behalf of the Lender has made any
representations to induce this waiver, that Debtor has been represented (or has
had the opportunity to be represented) in the signing of this Agreement and in
the making of this waiver by independent legal counsel selected by Debtor and
that Debtor has had the opportunity to discuss this waiver with counsel. Debtor
further agrees that any bankruptcy or insolvency proceeding initiated by Debtor
will only be brought in the Federal Court within the Southern District of New
York.

12. Miscellaneous.

      12.1 Expenses. Debtor shall pay to the Lender, on demand, the amount of
any and all reasonable expenses, including, without limitation, attorneys' fees,
legal expenses and brokers' fees, which the Lender may incur in connection with
(a) sale, collection or other enforcement or disposition of Collateral; (b)
exercise or enforcement of any the rights, remedies or powers of the Lender
hereunder or with respect to any or all of the Obligations upon breach or
threatened breach; or (c) failure by Debtor to perform and observe any
agreements of Debtor contained herein which are performed by the Lender.

      12.2 Waivers, Amendment and Remedies. No course of dealing by the Lender
and no failure by the Lender to exercise, or delay by the Lender in exercising,
any right, remedy or power hereunder shall operate as a waiver thereof, and no
single or partial exercise thereof shall preclude any other or further exercise
thereof or the exercise of any other right, remedy or power of the Lender. No
amendment, modification or waiver of any provision of this Agreement and no
consent to any departure by Debtor therefrom, shall, in any event, be effective
unless contained in a writing signed by the Lender, and then such waiver or
consent shall be effective only in the specific instance and for the specific
purpose for which given. The rights, remedies and powers of the Lender, not only
hereunder, but also under any instruments and agreements evidencing or securing
the Obligations and under applicable law are cumulative, and may be exercised by
the Lender from time to time in such order as the Lender may elect.

      12.3 Notices. All notices or other communications given or made hereunder
shall be in writing and shall be personally delivered or deemed delivered the
first business day after being faxed (provided that a copy is delivered by first

    Dear
      Paul:

    

    Reference
      is hereby made to your Offer Letter, dated July 17, 2006 (the “Offer Letter”),
      accepted by you on July 20, 2006, related to your employment as the Chief
      Financial Officer of Perficient, Inc. (the “Company”). 

    

    The
      Offer
      Letter provides for a restricted stock grant of 50,000 shares (the “Employee
      Grant”), subject to approval of the Compensation Committee of the Board of
      Directors of the Company, with a five year vesting schedule as set forth in
      the
      Offer Letter. The Restricted Stock Grant was approved by the Compensation
      Committee on August 29, 2006. As discussed, subject to further approval of
      the
      Compensation Committee, the Company has agreed to insert into Paragraph 6(a)
      of
      the Restricted Stock Award Agreement a special accelerated vesting provision
      that provides for 50% acceleration of vesting upon a Corporate Transaction,
      with
      further acceleration of all unvested stock in the event of your Involuntary
      Termination in connection with or within one year after a Corporate Transaction
      (as such terms are defined in the Restricted Stock Award
      Agreement).

    

    The
      Offer
      Letter also provides that “you will be eligible for severance compensation if
      you are terminated without cause up to one year following a change of control
      (as defined in the 1999 Perficient Stock Options/Stock Issuance Plan).” As
      discussed, the Company agrees to modify this provision of the Offer Letter
      such
      that you will be eligible for severance compensation (as provided therein)
      if
      you are subject to an Involuntary Termination in connection with or within
      one
      year following a Corporate Transaction (as such terms are defined in the
      Restricted Stock Award Agreement).

    

    The
      Offer
      Letter, as modified by this letter, together with the Restricted Stock Award
      Agreement (and related Notice of Grant) and other agreements referred to in
      the
      Offer Letter, contain all of the terms of your employment with the Company
      and
      supersede any prior understandings or agreements, whether oral or written,
      between you and the Company. Except as modified herein, the Offer Letter remains
      in full force and effect.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    If
      the
      foregoing terms are acceptable, please indicate your agreement by signing and
      dating this letter in the space provided below and returning to me.

    
 

    Sincerely,

    

    /s/
      Jeffrey Davis

      TO AND ACCEPTED BY:
