DOLLARS (US $3,400,000.00) together with accrued and unpaid interest
thereon, each due and payable on the dates and in the manner set forth
below.  This Subordinated Unsecured Promissory Note (this “Note”) is
made in connection with that certain Contribution Agreement, dated as of the
date hereof (the “Contribution Agreement”), by and among Company,
Seller, the members of Seller, The Analysis Group, LLC, a Virginia limited
liability company, and certain other parties thereto.  All capitalized
terms used but not defined herein shall have the respective meanings assigned
thereto in the Contribution Agreement.

     

    1.           Principal
Repayment.  Subject to Sections 5 and 7 hereof, the outstanding
principal amount of this Note shall be due and payable on the earlier of (i)
February 28, 2011; (ii) seven (7) days following an IPO Event (as defined
below); or (iii) simultaneous with a Change of Control (as defined below) (the
“Maturity
Date”).  Notwithstanding
the foregoing, all principal payments in respect of this Note shall be subject
to Section 8 of the Contribution Agreement, the Subordination Agreement (as
defined below), and subject to the provisions hereunder.

     

    2.           Interest Rate and
Payments.  Company further promises to pay interest on the
outstanding principal amount of this Note from the date hereof until payment in
full at an interest rate equal to three percent (3%) per annum, compounded
quarterly, and such interest shall be payable in full on the date that the
principal amount hereof is required to be paid hereunder.  All
computations of interest shall be made by Seller on the basis of a year of 360
days based upon the actual number of days elapsed.  Notwithstanding
the foregoing, all interest payments and late charges in respect of this Note
shall be subject to Section 8 of the Contribution Agreement, the Subordination
Agreement, and subject to the provisions hereunder.

     

    3.           Place of
Payment.  All amounts payable hereunder shall be payable in
immediately available funds to Seller at the address or to the wire transfer
account designated by Seller by prior written notice, which notice shall contain
wire transfer instructions, if applicable.

     

    4.           Application of
Payments.  Payment on this Note received by Seller shall be
applied first to late payment charges or other sums owned to Seller hereunder,
next to accrued interest, and thereafter to the outstanding balance of the
principal amount hereof.

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    5.           Deposit into
Escrow.  In the event of the consummation of an initial public
offering pursuant to an effective registration statement under the Securities
Act of 1933 of any securities of Company or any direct or indirect subsidiary of
Company (collectively, “HoldCo
Group”) (such
event is defined as an “IPO
Event”) or the
consummation of a Change of Control (as defined below) prior to February 28,
2011, the outstanding principal amount of this Note, together with accrued and
unpaid interest on such principal amount and any CGRC Payment (as defined below)
accrued up to the Maturity Date, shall be deposited, on the Maturity Date, into
an escrow account with TD Bank, N.A. or such other financial institution as may
be mutually agreed to by Company and Seller  (“Escrow
Agent”), pursuant to an escrow agreement to be mutually agreed in good
faith by and among Seller, Company and Escrow Agent, which escrow agreement
shall (i) provide that the amount held in escrow will be released on the one
year anniversary of the date hereof, less the amount of any unresolved claims
for indemnification made as of such date by Company in accordance with the
Contribution Agreement, and (ii) contain such other customary terms and
conditions as are mutually agreed upon by Seller, Company and Escrow
Agent.  Notwithstanding anything to the contrary herein, the
obligation of Company to deposit amounts outstanding under this Note in escrow
pursuant to this Section 5 and cancel this Note shall not be subordinated to
Senior Debt (as defined below) or subject to Section 12 below. Upon deposit of
the amount of the outstanding principal and accrued interest under this Note
into escrow in accordance with this Section 5, this Note shall be deemed paid in
full and cancelled.   For purposes of this Note, a “Change of
Control” shall mean (i) any change, in a single or series of related
transactions, of fifty percent (50%) or more of the combined voting power
of all classes of the voting equity or other economic interests (including
assets) of any member or members of the HoldCo Group whose revenue,
individually or combined, is equal to or greater than fifty percent (50%)
of the aggregate revenue of all members of the HoldCo Group immediately prior to
such transaction or series of related transactions; provided, that the
issuance of the equity of a member of the HoldCo Group as
consideration in connection with such member's acquisition of assets,
equity or other property of another Person or Persons shall not in any event
constitute a Change of Control, or (ii) (x) a sale, or other
disposition of a majority of the assets of Company, (y) a transfer or sale of
more than fifty percent (50%) of the combined voting power of all classes of the
voting equity of Company, or (z) a merger or consolidation involving
Company in which Company's voting equity interests outstanding immediately prior
to such merger or consolidation are converted by virtue of the merger into other
property, whether in the form of securities, cash or otherwise, and a third
party controls Company as a result.

     

    6.           Capital Gains Rate Change
Payment.   In the event that any principal, and/or other
payment (other than interest) under this Note is paid after December 31, 2010,
the amount of any such payment shall be increased by an amount equal to (i) the
amount of such payment multiplied by (ii) the
difference, if any, between (a) the U.S. federal long-term capital gains tax
rate applicable to Seller on the date that such payment is made and (b) the U.S.
federal long-term capital gains tax rate applicable to payments made in calendar
year 2010 (the "CGRC Payment").  Any CGRC Payment payable hereunder
shall be due and payable by Company to Seller on the date that any principal
payment is required to be paid pursuant to this Note.  In the event
that the U.S. federal long-term capital gains tax rate applicable to Seller on
the date that such payment is made is less than the U.S. federal long-term
capital gains tax rate applicable to payments made in calendar year 2010, the
amount of any payment under this Note shall be decreased by an amount equal to
(i) the amount of such payment multiplied by (ii) the
difference, if any, between (a) the U.S. federal long-term capital gains tax
rate applicable to Seller on the date that such payment is made and (b) the U.S.
federal long-term capital gains tax rate applicable to payments made in calendar
year 2010.

    7.           Prepayment. Company may, at its option at
any time and from time to time hereafter, prepay, in whole or part, without
premium or penalty, the outstanding principal amount of this Note, together with
accrued but unpaid interest on such principal amount to the date of
prepayment.

     

    8.           Default.  Each of
the following events shall be an “Event of
Default” hereunder:

     

    (a)             if
Company shall fail to pay timely any of the principal or interest due under this
Note on the date the same becomes due and payable and such default is not cured
within five (5) days following written notice thereof by Seller to
Company;

     

    (b)             if
Company shall fail to perform, in the time and manner required, any of its
obligations or covenants under, or shall fail to comply with any of the
provisions of, this Note, which does not involve the failure to make a payment
when due (be it principal or interest), and such default is not cured within
thirty (30) days following written notice thereof by Seller to
Company;

     

    (c)             if
a default or event of default with respect to any Senior Debt (as defined in
Section 12 below) has occurred and is continuing and the holders of such Senior
Debt have accelerated the maturity of such Senor Debt;

     

    (d)             if
any member of HoldCo Group files any petition or commences any case or other
proceeding with respect thereto for relief under any bankruptcy, reorganization,
arrangement, insolvency, readjustment of debt, liquidation, or moratorium law or
any other law for the relief of, or relating to, debtors, now or hereafter in
effect, or makes any assignment for the benefit of creditors, or admits in
writing its inability to pay or generally fails to pay its debts as they mature
or become due, or takes any corporate action in furtherance of any of the
foregoing; or

     

    (e)             if
an involuntary petition is filed or any case or other proceeding is commenced
against any member of HoldCo Group (unless such petition is dismissed or
discharged within ninety (90) days) under any bankruptcy, reorganization,
arrangement, insolvency, adjustment of debt, liquidation or moratorium statute
now or hereafter in effect, or a custodian, receiver, trustee, liquidator,
assignee for the benefit of creditors (or other similar official) is applied for
or appointed for any member of HoldCo Group or is applied for or appointed to
take possession, custody or control of any property of such member of HoldCo
Group.

     

    9.           Default Interest
Rate.  Upon and from the occurrence of any Event of Default
throughout the time that such Event of Default continues and remains uncured and
that any portion of the outstanding principal amount of this Note or any CGRC
Payment remains unpaid and outstanding, such outstanding principal amount and
outstanding CGRC Payment will bear interest at the rate equal to fourteen
percent (14%) per annum.

the occurrence of
an Event of Default the then-outstanding principal balance of this Note,
together with any accrued but unpaid interest on such principal amount and all
other sums payable, shall at the option of Seller become immediately due and
payable.  Notwithstanding the foregoing, if there shall occur an Event
of Default under Section 8(d) or 8(e) above, the then-outstanding principal
balance of this Note, together with any accrued but unpaid interest on such
principal amount and all other sums payable, shall become immediately due and
payable without any action on the part of Seller.

     

    11.           Setoff Under the Contribution
Agreement.

     

    (a)  By
the making and acceptance of this Note, Seller and Company agree that Company
shall have the right, pursuant to the terms hereof, to setoff against unpaid
payment of amounts due hereunder any amounts due to Company by Seller in
accordance with Section 8.2 (Indemnification by the Members and Contributor) of
the Contribution Agreement. With respect to any proposed setoff, Company shall
deliver to Seller a written notice describing the amount of the proposed setoff
and the reasons therefor.  Any such claim for set-off by Company is
required to be made within the applicable time period for such claim under the
Contribution Agreement.

     

    (b)  In
the event that Company makes any claim against Seller in accordance with the
Contribution Agreement, subject to the
limitations, restrictions and other terms and conditions set forth in the
Contribution Agreement (such claim, a “Claim”),
Company’s obligations to pay the amount of principal due hereunder equal to the
amount of all such Claims shall be suspended until the Claim that is the basis
for the proposed set off is either (i) resolved by the parties in writing or
(ii) finally resolved by a court pursuant to the Contribution Agreement (the
resolution of a Claim under subsection (i) or (ii) above is referred to as
“Final
Resolution”).  If pursuant to a Final Resolution, Company is
entitled to a set off, such set off shall be effective as of the date of the
Final Resolution.  If pursuant to the Final Resolution, Company is not
entitled to a set off, any payments of principal suspended due to the Claim
shall be paid by Company to Seller, together with interest at a rate equal to
fourteen percent (14%) per annum accruing from the date such amounts would have
been paid to Seller pursuant to this Note had the Claim not been made until such
amount is paid in full and three percent (3%) per annum for periods prior to the
date that such amounts would have been paid to Seller pursuant to this
Note.  Any payment required under this Section 11 shall be paid within
ten (10) days of the date of Final Resolution that applies to such
payment.  Upon the determination of any set off hereunder, Company
shall promptly deliver to Seller a notice which shall set forth the remaining
principal balance of the Note.

     

    12.           Subordination.  The
rights of Seller under this Note are expressly subordinate to the indebtedness
and other obligations to Bank of America, N.A. (the “Bank”)
pursuant to the terms of the that certain subordination agreement, dated
February 22, 2010 executed by Seller and accepted by the Bank and Company,
subordinating this Note to the Bank’s indebtedness (the “Subordination
Agreement”), and to Company’s future non-affiliated lenders of Senior
Debt to the extent provided in any future subordination agreement Seller enters
into pursuant to the terms of this Section 12; provided that any future
subordinations shall exclude Company’s obligations under Sections 1(ii), 1(iii)
and 5 hereof and shall incorporate the limitations of this Section 12. Without
limiting the terms of the Subordination Agreement, by accepting this Note,
Seller hereby agrees, upon the written request of Company, to enter into
additional subordination agreements containing such commercially reasonable
terms and conditions as Seller and such lender(s) mutually agree upon (which
terms and conditions may be less restrictive than those in the Subordination
Agreement) for the purposes of subordinating payment of the indebtedness
evidenced by this Note to any other future senior or mezzanine secured
indebtedness of Company held by the Bank or another financial institution
(collectively “Senior
Debt”); provided, that no such future subordination agreements shall
contain terms and conditions more adverse to Seller or more restrictive with
respect to Seller’s right to payments hereunder, than those contained in the
Subordination Agreement.

of such payment, Company agrees to comply with the following
covenants:

     

    (a)  Company
shall cause this Note to be senior in right of payment to any other subordinated

their affiliates);

     

    (b)  Company
shall not redeem or purchase securities in Company from any equity holder of
Company (other than Seller) without the prior written consent of Seller until

Seller; and

     

    (d)  Company

Company.

delayed), provided that any such transferee, assignee or pledgee shall be
subject to all of the terms and conditions of this Note, including, without
limitation, Sections 11 and 12 and any subordination agreement executed by
Seller with respect to this Note.

     

    16.           Third Party
Beneficiaries.  The provisions contained in Section 12 of this
Note are and will be for the benefit of any third party that is a holder of
Senior Debt; and, accordingly, any such third party shall have the right to
enforce such provisions of this Note.

     

    17.           Enforcement
Costs.  Should the indebtedness represented by this Note or any
part hereof be collected in any proceeding, Seller shall be entitled to collect

attorneys’ fees.  In addition, and without duplication, following an
Event of Default, Company shall be required to pay all reasonable attorney’s

circumstances where suit is not brought, so long as the actions taken by Seller
are in compliance with and permitted under this Note or any other written
agreements signed by Seller regarding the indebtedness contemplated
hereby.

when due (be it principal or interest) and such default is not cured within
thirty (30) days following written notice thereof by Holder to
Company;

     

    (c)             if
a default or event of default with respect to any Senior Debt (as defined below)

against any member of HoldCo Group (unless such petition is dismissed or
discharged within ninety (90) days) under any bankruptcy, reorganization,
arrangement, insolvency, adjustment of debt, liquidation or moratorium statute
now or hereafter in effect, or a custodian, receiver, trustee, liquidator,

Rate.  Upon and from the occurrence of any Event of Default
throughout the time that such Event of Default continues and remains uncured and

and outstanding, such outstanding principal amount will bear interest at the
rate equal to fourteen percent (14%) per annum, compounding
quarterly.

     

    8.           Remedies.  Upon
the occurrence of
an Event of Default which continues beyond
any applicable grace or cure period, the then-outstanding principal balance of
this Note, together with any accrued but unpaid interest on such principal
amount and all other sums payable, shall at the option of Holder become
immediately due and payable.  Notwithstanding the foregoing, if there
shall occur an Event of Default under Section 6(d) or 6(e) above, the
then-outstanding principal balance of this Note, together with any accrued but
unpaid interest on such principal amount and all other sums payable, shall
become immediately due and payable without any action on the part of
Holder.
