Agent agree as follows:

                                   SECTION 1.
                           AMOUNTS AND TERMS OF LOANS
                           --------------------------

         1.1      LOANS.
                  ------

         Subject to the terms and conditions of this Agreement and in reliance
upon the representations and warranties of Borrower and the other Credit Parties
contained herein:

         (a) TERM LOAN B. Each Term Lender agrees, severally and not jointly, to
lend to Borrower in one draw, on the Closing Date, its Pro Rata Share of the
aggregate amount of $225,000,000 (the "TERM LOAN B"). Borrower shall repay Term
Loan B through periodic payments on the dates and in the amounts indicated below
("SCHEDULED INSTALLMENTS").

          DATE                                             SCHEDULED INSTALLMENT
          ----                                             ---------------------

          Beginning with March 31, 2007, each              $562,500
          March 31, June 30, September 30
          and December 31 occurring prior to
          September 30, 2012

          November 15, 2012                                $212,625,000


         The final installment shall in all events equal the entire remaining
principal balance of the Term Loan B. Notwithstanding the foregoing, the
outstanding principal balance of the Term Loan B shall be due and payable in
full on the Commitment Termination Date. Amounts borrowed under this SECTION
1.1(a) and repaid may not be reborrowed.

         At the request of the applicable Lender, such Lender's Term Loan B
shall be evidenced by promissory notes substantially in the form of EXHIBIT
1.1(a) (as amended, modified, extended, substituted or replaced from time to
time, each a "TERM NOTE B" and, collectively, the "TERM NOTES B"), and, except
as provided in SECTION 1.7, Borrower shall execute and deliver each Term Note B
to the applicable Lender. Each Term Note B shall represent the obligation of
Borrower to pay the amount of the applicable Lender's Term Loan B Commitment,
together with interest thereon.

                                       2

         (b)      REVOLVING LOANS.
                  ----------------

                  (i) Each Revolving Lender agrees, severally and not jointly,
to make available to Borrower from time to time until the Commitment Termination
Date its Pro Rata Share of advances (each a "REVOLVING CREDIT ADVANCE")
requested by Borrower hereunder. The Pro Rata Share of the Revolving Loan of any
Revolving Lender (including, without duplication, Swing Line Loans) shall not at
any time exceed its separate Revolving Loan Commitment. Revolving Credit
Advances may be repaid and reborrowed; provided, that the amount of any
Revolving Credit Advance to be made at any time shall not exceed Borrowing
Availability. The Revolving Loans shall be repaid in full on the Commitment
Termination Date. If requested by a Revolving Lender, Borrower shall execute and
deliver to such Revolving Lender a note to evidence the Revolving Loan
Commitment of that Revolving Lender. Each such note shall be in the maximum
principal amount of the Revolving Loan Commitment of the applicable Revolving
Lender, dated the Closing Date and substantially in the form of EXHIBIT
1.1(b)(i) (as amended, modified, extended, substituted or replaced from time to
time, each a "REVOLVING NOTE" and, collectively, the "REVOLVING NOTES"). If at
any time the aggregate outstanding Revolving Loan exceeds the Borrowing Base
(any such excess Revolving Loan is herein referred to as an "OVERADVANCE"),
Lenders shall not be obligated to make Revolving Credit Advances, no additional
Letters of Credit shall be issued and the Revolving Loan must be repaid
immediately and Letters of Credit cash collateralized in an amount sufficient to
eliminate any Overadvance. All Overadvances shall constitute Index Rate Loans
and at the written request of Agent or the Requisite Lenders shall bear interest
at the Index Rate plus the Revolving Loan Applicable Index Rate Margin and shall
bear interest at the Default Rate only if not repaid within three (3) Business
Days. For funding requests for Revolving Credit Advances to be funded as Index
Rate Loans of $5,000,000 or less, written notice must be provided by 1:00 p.m.
(New York time) on the Business Day on which the Revolving Credit Advance is to
be made; for funding requests for Revolving Credit Advances to be funded as
Index Rate Loans of more than $5,000,000, written notice must be provided by
1:00 p.m. (New York time) on the Business Day before which the Revolving Credit
Advance is to be made. All Revolving Credit Advances to be funded as LIBOR Loans
require three (3) Business Days prior written notice. Written notices for all
funding requests shall be in the form attached as EXHIBIT 1.1(b)(ii) ("NOTICE OF
REVOLVING CREDIT ADVANCE").

         (c)      SWING LINE FACILITY.
                  --------------------

                  (i) Agent shall notify the Swing Line Lender upon Agent's
receipt of any Notice of Revolving Credit Advance. Subject to the terms and
conditions hereof, the Swing Line Lender may, in its discretion, make available
from time to time until the Commitment Termination Date advances (each, a "SWING
LINE ADVANCE") in accordance with any such notice. The provisions of this
SECTION 1.1(c) shall not relieve Revolving Lenders of their obligations to make
Revolving Credit Advances under SECTION 1.1(b); provided that if the Swing Line
Lender makes a Swing Line Advance pursuant to any such notice, such Swing Line
Advance shall be in lieu of any Revolving Credit Advance that otherwise may be
made by Revolving Lenders pursuant to such notice. Except as provided in SECTION
1.1(b)(ii) above, the aggregate amount of Swing Line Advances outstanding shall
not exceed at any time the lesser of (A) the Swing Line Commitment and (B)
Borrowing Availability ("SWING LINE AVAILABILITY"). Until the Commitment


                                       3

 Termination Date, Borrower may from time to time borrow, repay and reborrow
under this SECTION 1.1(c). Each Swing Line Advance shall be made pursuant to a
Notice of Revolving Credit Advance delivered by Borrower to Agent in accordance
with SECTION 1.1(b). Unless the Swing Line Lender has received at least one (1)
Business Day's prior written notice from Requisite Revolving Lenders instructing
it not to make a Swing Line Advance, the Swing Line Lender shall,
notwithstanding the failure of any condition precedent set forth in SECTION 2.2,
be entitled to fund that Swing Line Advance, and to have each Revolving Lender
make Revolving Credit Advances in accordance with SECTION 1.1(c)(iii) or
purchase participating interests in accordance with SECTION 1.1(c)(iv).
Notwithstanding any other provision of this Agreement or the other Loan
Documents, the Swing Line Loan shall constitute an Index Rate Loan. Unless
refunded as a Revolving Loan as provided in Section 1.1(c)(iii) below, Borrower
shall repay the aggregate outstanding principal amount of the Swing Line Loan
upon demand therefor by Agent. The entire unpaid balance of the Swing Line Loan
and all other noncontingent Obligations shall be immediately due and payable in
full in immediately available funds on the Commitment Termination Date if not
sooner paid in full.

                  (ii) Borrower shall execute and deliver to the Swing Line
Lender a promissory note to evidence the Swing Line Commitment. Such note shall
be in the principal amount of the Swing Line Commitment of the Swing Line
Lender, dated the Closing Date and substantially in the form of EXHIBIT 1.1(c)
(as amended, modified, extended, substituted or replaced from time to time, the
"SWING LINE NOTE"). The Swing Line Note shall represent the obligation of
Borrower to pay the amount of the Swing Line Commitment or, if less, the
aggregate unpaid principal amount of all Swing Line Advances made to Borrower
together with interest thereon as prescribed in SECTION 1.2.

                  (iii) The Swing Line Lender, at any time and from time to time
in its sole and absolute discretion but no less frequently than once each week,
shall on behalf of Borrower (and Borrower hereby irrevocably authorizes the
Swing Line Lender to so act on its behalf) request each Revolving Lender
(including the Swing Line Lender) to make a Revolving Credit Advance to Borrower
(which shall be an Index Rate Loan) in an amount equal to that Revolving
Lender's Pro Rata Share of the principal amount of the Swing Line Loan (the
"REFUNDED SWING LINE LOAN") outstanding on the date such notice is given. Unless
any of the events described in SECTIONS 7.1(f) and 7.1(g) has occurred and is
continuing (in which event the procedures of SECTION 1.1(c)(iv) shall apply) and
regardless of whether the conditions precedent set forth in this Agreement to
the making of a Revolving Credit Advance are then satisfied, each Revolving
Lender shall disburse directly to Agent, its Pro Rata Share of a Revolving
Credit Advance on behalf of the Swing Line Lender, prior to 3:00 p.m. (New York
time), in immediately available funds on the Business Day next succeeding the
date that notice is given. The proceeds of those Revolving Credit Advances shall
be immediately paid to the Swing Line Lender and applied to repay the Refunded
Swing Line Loan.

                  (iv) If, prior to refunding a Swing Line Loan with a Revolving
Credit Advance pursuant to SECTION 1.1(c)(iii), one of the events described in
SECTIONS 7.1(f) or 7.1(g) has occurred and is continuing, then, subject to the
provisions of SECTION 1.1(c)(v) below, each Revolving Lender shall, on the date
such Revolving Credit Advance was to have been made for the benefit of Borrower,
purchase from the Swing Line Lender an undivided participation interest in the
Swing Line Loan in an amount equal to its Pro Rata Share (determined with
respect to Revolving Loans) of such Swing Line Loan. Upon request, each
Revolving Lender shall promptly transfer to the Swing Line Lender, in
immediately available funds, the amount of its participation interest.

                                       4

                  (v) Each Revolving Lender's obligation to make Revolving
Credit Advances in accordance with SECTION 1.1(c)(iii) and to purchase
participation interests in accordance with SECTION 1.1(c)(iv) shall be absolute
and unconditional and shall not be affected by any circumstance, including (A)
any setoff, counterclaim, recoupment, defense or other right that such Revolving
Lender may have against the Swing Line Lender, Borrower or any other Person for
any reason whatsoever; (B) the occurrence or continuance of any Default or Event
of Default; (C) any inability of Borrower to satisfy the conditions precedent to
borrowing set forth in this Agreement at any time or (D) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing.
Swing Line Lender shall be entitled to recover, on demand, from each Revolving
Lender the amounts required pursuant to SECTIONS 1.1.(c)(iii) or 1.1(c)(iv), as
the case may be. If any Revolving Lender does not make available such amounts to
Agent or the Swing Line Lender, as applicable, the Swing Line Lender shall be
entitled to recover, on demand, such amount from such Revolving Lender, together
with interest thereon for each day from the date of non-payment until such
amount is paid in full at the Federal Funds Rate for the first two Business Days
and at the Index Rate thereafter.

         (d) LETTERS OF CREDIT. The Revolving Loan Commitment may, in addition
to advances under the Revolving Loan, be utilized (subject to the limitations
imposed by SECTION 1.1(A)), upon the request of Borrower, for the issuance of
Letters of Credit. The parties hereto agree that the following letters of credit
previously issued Wachovia Bank, National Association shall constitute Letters
of Credit hereunder: (1) letter of credit no. SM211659W issued to Liberty Mutual
in the face amount of $657,027 with an expiration date of December 6, 2006 and
(2) letter of credit no. SM419633P issued to Safety National Casualty Corp. in
the face amount of $750,000 with an expiration date of December 30, 2006.
Immediately upon the issuance by an L/C Issuer of a Letter of Credit, and
without further action on the part of Agent or any of the Lenders, each
Revolving Lender shall be deemed to have purchased from such L/C Issuer a
participation in such Letter of Credit (or in its obligation under a risk
participation agreement with respect thereto) equal to such Revolving Lender's
Pro Rata Share of the aggregate amount available to be drawn under such Letter
of Credit.

                  (i) MAXIMUM AMOUNT. The aggregate amount of Letter of Credit
Obligations with respect to all Letters of Credit outstanding or unreimbursed at
any time shall not exceed $7,500,000 ("L/C SUBLIMIT").

                  (ii) REIMBURSEMENT. Borrower shall be irrevocably and
unconditionally obligated forthwith without presentment, demand, protest or
other formalities of any kind, to reimburse any L/C Issuer on demand in
immediately available funds for any amounts paid by such L/C Issuer with respect
to a Letter of Credit, including all reimbursement payments, Fees, Charges,
costs and expenses paid by such L/C Issuer, without duplication of fees
otherwise paid by Borrower. Borrower hereby authorizes and directs Agent, at
Agent's option, to debit Borrower's account (by increasing the outstanding
principal balance of the Revolving Credit Advances or Swing Line Advances made
to Borrower) in the amount of any payment made by an L/C Issuer with respect to


                                       5

 any Letter of Credit, and a Notice of Revolving Credit Advance requesting an
Index Rate Loan in such amount shall be deemed to have been timely given on such
date. All amounts paid by an L/C Issuer with respect to any Letter of Credit
that are not immediately repaid by Borrower with the proceeds of a Revolving
Credit Advance, Swing Line Advance or otherwise shall bear interest payable on
demand at the interest rate applicable to Revolving Credit Advances which are
Index Rate Loans plus, at the election of Agent or Requisite Revolving Lenders,
an additional two percent (2.00%) per annum. Each Revolving Lender agrees to
fund its Pro Rata Share of any Revolving Loan made pursuant to this SECTION
1.1(d)(ii). In the event Agent elects not to debit Borrower's account and
Borrower fails to reimburse the L/C Issuer in full on the date of any payment in
respect of a Letter of Credit, Agent shall promptly notify each Revolving Lender
of the amount of such unreimbursed payment and the accrued interest thereon and
each Revolving Lender, on the next Business Day prior to 3:00 p.m. (New York
time), shall deliver to Agent an amount equal to its Pro Rata Share thereof in
same day funds. Each Revolving Lender hereby absolutely and unconditionally
agrees to pay to the L/C Issuer upon demand by the L/C Issuer such Revolving
Lender's Pro Rata Share of each payment made by the L/C Issuer in respect of a
Letter of Credit and reimbursed within one (1) Business Day by Borrower or
satisfied through a debit of Borrower's account. Each Revolving Lender
acknowledges and agrees that its obligations pursuant to this subsection in
respect of Letters of Credit are absolute and unconditional and shall not be
affected by any circumstance whatsoever, including setoff, counterclaim, the
occurrence and continuance of a Default or an Event of Default or any failure by
Borrower to satisfy any of the conditions set forth in SECTION 2.2. If any
Revolving Lender fails to make available to the L/C Issuer the amount of such
Revolving Lender's Pro Rata Share of any payments made by the L/C Issuer in
respect of a Letter of Credit as provided in this SECTION 1.1(d)(ii), the L/C
Issuer shall be entitled to recover such amount on demand from such Revolving
Lender together with interest at the Index Rate.

                  (iii) REQUEST FOR LETTERS OF CREDIT. Borrower shall give Agent
at least three (3) Business Days prior written notice specifying the date a
Letter of Credit is requested to be issued, the amount and the name and address
of the beneficiary and a description of the transactions proposed to be
supported thereby, and the expiry date (or extended expiry date) of the Letter
of Credit. Each request by Borrower for the issuance of a Letter of Credit shall
be in the form of EXHIBIT 1.1(d). If Agent informs Borrower that the L/C Issuer
cannot issue the requested Letter of Credit directly, Borrower may request that
L/C Issuer arrange for the issuance of the requested Letter of Credit under a
risk participation agreement with another financial institution reasonably
acceptable to Agent, L/C Issuer and Borrower. The issuance of any Letter of
Credit under this Agreement shall be subject to satisfaction of the conditions
set forth in SECTION 2.2 and the conditions that the Letter of Credit (i)
supports a transaction benefiting Borrower or its wholly-owned Subsidiaries and
(ii) is in a form, is for an amount and contains such terms and conditions as
are reasonably satisfactory to the L/C Issuer and, in the case of standby
letters of credit, Agent. The initial notice requesting the issuance of a Letter
of Credit shall be accompanied by the form of the Letter of Credit and the
Master Standby Agreement or Master Documentary Agreement, as applicable, and an
application for a Letter of Credit, if any, then required by the L/C Issuer
completed in a manner reasonably satisfactory to such L/C Issuer. If any
provision of any application or reimbursement agreement is inconsistent with the
terms of this Agreement, then the provisions of this Agreement, to the extent of
such inconsistency, shall control.

                                       6

                  (iv) EXPIRATION DATES OF LETTERS OF CREDIT. The expiration
date of each Letter of Credit shall be on a date which is not later than the
earlier of (a) one year from its date of issuance or (b) the tenth (10th) day
prior to the date set forth in clause (a) of the definition of the term
Commitment Termination Date. Notwithstanding the foregoing, a Letter of Credit
may provide for automatic extensions of its expiration date for one (1) or more
successive one (1) year periods provided that upon not less than 30 days written
notice to Borrower, the L/C Issuer has the right to terminate such Letter of
Credit on each such annual expiration date and no renewal term may extend the
term of the Letter of Credit to a date that is later than the tenth (10th) day
prior to the date set forth in clause (a) of the definition of the term
Commitment Termination Date. The L/C Issuer may elect not to renew any such
Letter of Credit and, upon direction by Agent or Requisite Revolving Lenders,
shall not renew any such Letter of Credit at any time during the continuance of
an Event of Default, provided that, in the case of a direction by Agent or
Requisite Revolving Lenders, the L/C Issuer receives such directions prior to
the date notice of non-renewal is required to be given by the L/C Issuer and the
L/C Issuer has had a reasonable period of time to act on such notice.

                  (v) OBLIGATIONS ABSOLUTE. The obligation of Borrower to
reimburse the L/C Issuer, Agent and Lenders for payments made in respect of
Letters of Credit issued by the L/C Issuer shall be unconditional and
irrevocable and shall be paid under all circumstances strictly in accordance
with the terms of this Agreement, including the following circumstances: (a) any
lack of validity or enforceability of any Letter of Credit; (b) any amendment or
waiver of or any consent or departure from all or any of the provisions of any
Letter of Credit or any Loan Document; (c) the existence of any claim, set-off,
defense or other right which Borrower, any of its Subsidiaries or Affiliates or
any other Person may at any time have against any beneficiary of any Letter of
Credit, Agent, any L/C Issuer, any Lender or any other Person, whether in
connection with this Agreement, any other Loan Document or any other related or
unrelated agreements or transactions; (d) any draft or other document presented
under any Letter of Credit proving to be forged, fraudulent, invalid or
insufficient in any respect or any statement therein being untrue or inaccurate
in any respect; (e) payment under any Letter of Credit against presentation of a
draft or other document that does not substantially comply with the terms of
such Letter of Credit; or (f) any other act or omission to act or delay of any
kind of any L/C Issuer, Agent, any Lender or any other Person or any other event
or circumstance whatsoever that might, but for the provisions of this SECTION
1.1(d)(v), constitute a legal or equitable discharge of Borrower's obligations
hereunder. Without limiting the generality of the foregoing, it is expressly
understood and agreed by Borrower that the absolute and unconditional obligation
of Borrower to Agent and Lenders hereunder to reimburse payments made under a
Letter of Credit will not be excused by the gross negligence or willful
misconduct of the L/C Issuer. However, the foregoing shall not be construed to
excuse an L/C Issuer from claims which Borrower may assert against the L/C
Issuer subject to the terms of the Master Standby Agreement or the Master
Documentary Agreement.

                  (vi) OBLIGATIONS OF L/C ISSUERS. Each L/C Issuer (other than
GE Capital) hereby agrees that it will not issue a Letter of Credit hereunder
until it has provided Agent with written notice specifying the amount and
intended issuance date of such Letter of Credit and Agent has returned a written
acknowledgment of such notice to L/C Issuer (such notices and acknowledgements
to be given promptly). Each L/C Issuer (other than GE Capital) further agrees to
provide to Agent: (a) a copy of each Letter of Credit issued by such L/C Issuer


                                       7

 promptly after its issuance; (b) a weekly report summarizing available amounts
under Letters of Credit issued by such L/C Issuer, the dates and amounts of any
draws under such Letters of Credit, the effective date of any increase or
decrease in the face amount of any Letters of Credit during such week and the
amount of any unreimbursed draws under such Letters of Credit; and (c) such
additional information reasonably requested by Agent from time to time with
respect to the Letters of Credit issued by such L/C Issuer.

         (e)      SWAP RELATED REIMBURSEMENT OBLIGATIONS.
                  ---------------------------------------

                  (i) Borrower agrees to reimburse GE Capital in immediately
available funds in the amount of any payment made by GE Capital under a Swap
Related L/C (such reimbursement obligation, whether contingent upon payment by
GE Capital under the Swap Related L/C or otherwise, being herein called a "SWAP
RELATED REIMBURSEMENT OBLIGATION"). No Swap Related Reimbursement Obligation for
any Swap Related L/C may exceed the amount of the payment obligations owed by
Borrower under the interest rate protection or hedging agreement or transaction
supported by the Swap Related L/C.

                  (ii) A Swap Related Reimbursement Obligation shall be due and
payable by Borrower within one (1) Business Day after the date on which the
related payment is made by GE Capital under the Swap Related L/C.

                  (iii) Any Swap Related Reimbursement Obligation shall, during
the period in which it is unpaid, bear interest at the rate per annum equal to
the LIBOR Rate plus one percent (1%), as if the unpaid amount of the Swap
Related Reimbursement Obligation were a LIBOR Loan, and not at any otherwise
applicable Default Rate. Such interest shall be payable upon demand. The
following additional provisions apply to the calculation and charging of
interest by reference to the LIBOR Rate:

                           (A) The LIBOR Rate shall be determined for each
         successive one-month LIBOR Period during which the Swap Related
         Reimbursement Obligation is unpaid, notwithstanding the occurrence of
         any Event of Default and even if the LIBOR Period were to extend beyond
         the Commitment Termination Date.

                           (B) If a Swap Related Reimbursement Obligation is
         paid during a monthly period for which the LIBOR Rate is determined,
         interest shall be pro-rated and charged for the portion of the monthly
         period during which the Swap Related Reimbursement Obligation was
         unpaid. SECTION 1.2(d) shall not apply to any payment of a Swap Related
         Reimbursement Obligation during the monthly period.

                           (C) Notwithstanding the last sentence of the
         definition of "LIBOR Rate", with respect to Swap Related Reimbursement
         Obligations if the LIBOR Rate is no longer available from Telerate News
         Service, the LIBOR Rate shall be determined by GE Capital from such
         financial reporting service or other information available to GE
         Capital as in GE Capital's reasonable discretion indicates GE Capital's
         cost of funds.

                  (iv) Except as provided in the foregoing provisions of this
SECTION 1.1(e) and in SECTION 1.3(e), Borrower shall not be obligated to pay to
GE Capital or any of its Affiliates any Letter of Credit Fee, or any other fees,


                                       8

 charges or expenses, in respect of a Swap Related L/C or arranging for any
interest rate protection or hedging agreement or transaction supported by the
Swap Related L/C. GE Capital and its Affiliates shall look to the beneficiary of
a Swap Related L/C for payment of any such letter of credit fees or other fees,
charges or expenses and such beneficiary may factor such fees, charges, or
expenses into the pricing of any interest rate protection or hedging arrangement
or transaction supported by the Swap Related L/C.

                  (v) If any Swap Related L/C is revocable prior to its
scheduled expiry date, GE Capital agrees not to cause or permit the Swap Related
L/C to be revoked unless the Commitment Termination Date or an Event of Default
has occurred.

                  (vi) GE Capital or any of its Affiliates shall be permitted to
(i) provide confidential or other information furnished to it by any of the
Credit Parties (including, without limitation, copies of any documents and
information in or referred to in the Closing Checklist, Financial Statements and
Compliance Certificates) to a beneficiary or potential beneficiary of a Swap
Related L/C and (ii) receive confidential or other information from the
beneficiary or potential beneficiary relating to any agreement or transaction
supported or to be supported by the Swap Related L/C. However, no confidential
information shall be provided to any Person under this paragraph unless the
Person has agreed to comply with the covenant substantially as contained in
SECTION 9.13 of this Agreement.

                  (f) FUNDING AUTHORIZATION. The proceeds of all Loans made
pursuant to this Agreement subsequent to the Closing Date are to be funded by
Agent by wire transfer to the account designated by Borrower below (the
"DISBURSEMENT ACCOUNT"):

                  Bank:             City National Bank
                  ABA No.:          122016066
                  Bank Address:     400 N. Roxbury Dr., Beverly Hills, CA
                                        90210-5002
                  Account No.:      001-477-951
                  Reference:        Radnet Management, Inc.

Borrower shall provide Agent with written notice of any change in the foregoing
instructions at least three (3) Business Days before the desired effective date
of such change.

         1.2      INTEREST AND APPLICABLE MARGINS.
                  --------------------------------

                  (a) Borrower shall pay interest to Agent, for the ratable
benefit of Lenders with respect to the various Loans made by each Lender (or in
the case of the Swing Line Loan, for the benefit of the Swing Line Lender), in
arrears on each applicable Interest Payment Date, at the following rates: (i)
with respect to the Revolving Credit Advances which are designated as Index Rate
Loans (and for all other Obligations not otherwise set forth below), the Index
Rate plus the Applicable Revolver Index Margin per annum or, with respect to
Revolving Credit Advances which are designated as LIBOR Loans, at the election
of Borrower, the applicable LIBOR Rate plus the Applicable Revolver LIBOR Margin
per annum; (ii) with respect to such portion of the Term Loan B designated as an
Index Rate Loan, the Index Rate plus the Applicable Term Loan B Index Margin per


                                       9

 annum or, with respect to such portion of the Term Loan B designated as a LIBOR
Loan, the applicable LIBOR Rate plus the Applicable Term Loan B LIBOR Margin per
annum; and (iii) with respect to the Swing Line Loan, the Index Rate plus the
Applicable Revolver Index Margin per annum.

   The Applicable Margins are as follows:

             Applicable Revolver Index Margin                      2.00%

             Applicable Revolver LIBOR Margin                      3.50%

             Applicable Term Loan B Index Margin                   2.00%

             Applicable Term Loan B LIBOR Margin                   3.50%

             Applicable L/C Margin                                 3.50%

             Applicable Unused Line Fee Margin                     0.50%

                  (b) If any payment on any Loan becomes due and payable on a
day other than a Business Day, the maturity thereof will be extended to the next
succeeding Business Day (except as set forth in the definition of LIBOR Period)
and, with respect to payments of principal, interest thereon shall be payable at
the then applicable rate during such extension.

                  (c) All computations of Fees calculated on a per annum basis
and interest shall be made by Agent on the basis of a 360-day year, in each case
for the actual number of days occurring in the period for which such Fees and
interest are payable. The Index Rate is a floating rate determined for each day.
Each determination by Agent of an interest rate and Fees hereunder shall be
presumptive evidence of the correctness of such rates and Fees.

                  (d) So long as an Event of Default has occurred and is
continuing under SECTION 7.1(a), (f) or (g) and without notice of any kind, or
so long as any other Event of Default has occurred and is continuing and at the
election of Agent (or upon the written request of Requisite Lenders) confirmed
by written notice from Agent to Borrower, the interest rates applicable to the
Loans and the Letter of Credit Fee shall be increased by two percentage points
(2%) per annum above the rates of interest or the rate of such Fee otherwise
applicable hereunder ("DEFAULT RATE"), and the outstanding principal balance of
the Loans shall bear interest at the Default Rate applicable to such
Obligations. Interest and Letter of Credit Fees at the Default Rate shall accrue
from the initial date of such Event of Default until that Event of Default is
cured or waived and shall be payable upon demand, but in any event, shall be
payable on the next regularly scheduled payment date set forth herein for such
Obligation.

                  (e) Borrower shall have the option to (i) request that any
Revolving Credit Advance be made as a LIBOR Loan, (ii) convert at any time all
or any part of outstanding Loans (other than the Swing Line Loan) from Index
Rate Loans to LIBOR Loans, (iii) convert any LIBOR Loan to an Index Rate Loan,
subject to payment of the LIBOR Breakage Costs in accordance with SECTION 1.3(d)
if such conversion is made prior to the expiration of the LIBOR Period
applicable thereto, or (iv) continue all or any portion of any Loan (other than


                                       10

 the Swing Line Loan) as a LIBOR Loan upon the expiration of the applicable LIBOR
Period and the succeeding LIBOR Period of that continued Loan shall commence on
the first day after the last day of the LIBOR Period of the Loan to be
continued. Any Loan or group of Loans having the same proposed LIBOR Period to
be made or continued as, or converted into, a LIBOR Loan must be in a minimum
amount of $5,000,000 and integral multiples of $500,000 in excess of such
amount. Any such election must be made by 1:00 p.m. (New York time) on the 3rd
Business Day prior to (1) the date of any proposed Revolving Credit Advance
which is to bear interest at the LIBOR Rate, (2) the end of each LIBOR Period
with respect to any LIBOR Loans to be continued as such, or (3) the date on
which Borrower wishes to convert any Index Rate Loan to a LIBOR Loan for a LIBOR
Period designated by Borrower in such election. If no election is received with
respect to a LIBOR Loan by 1:00 p.m. (New York time) on the 3rd Business Day
prior to the end of the LIBOR Period with respect thereto, that LIBOR Loan shall
be converted to an Index Rate Loan at the end of its LIBOR Period. Borrower must
make such election by notice to Agent in writing, by fax or overnight courier
(or by telephone, to be confirmed in writing on such day). In the case of any
conversion or continuation, such election must be made pursuant to a written
notice (a "NOTICE OF CONVERSION/CONTINUATION") in the form of EXHIBIT 1.2(e). No
Loan shall be made, converted into or continued as a LIBOR Loan, if an Event of
Default has occurred and is continuing and Agent or Requisite Lenders have
determined not to make or continue any Loan as a LIBOR Loan as a result thereof.
No Loan may be made as or converted into a LIBOR Loan until the earlier of (i)
45 days after the Closing Date or (ii) completion of the primary syndication as
determined by Agent.

                  (f) Notwithstanding anything to the contrary set forth in this
SECTION 1.2, if a court of competent jurisdiction determines in a final order
that the rate of interest payable hereunder exceeds the highest rate of interest
permissible under law (the "MAXIMUM LAWFUL RATE"), then so long as the Maximum
Lawful Rate would be so exceeded, the rate of interest payable hereunder shall
be equal to the Maximum Lawful Rate; provided, however, that if at any time
thereafter the rate of interest payable hereunder is less than the Maximum
Lawful Rate, Borrower shall continue to pay interest hereunder at the Maximum
Lawful Rate until such time as the total interest received by Agent, on behalf
of Lenders, is equal to the total interest that would have been received had the
interest rate payable hereunder been (but for the operation of this paragraph)
the interest rate payable since the Closing Date as otherwise provided in this
Agreement. Thereafter, interest hereunder shall be paid at the rate(s) of
interest and in the manner provided in SECTIONS 1.2(a) through (e), unless and
until the rate of interest again exceeds the Maximum Lawful Rate, and at that
time this paragraph shall again apply. In no event shall the total interest
received by any Lender pursuant to the terms hereof exceed the amount that such
Lender could lawfully have received had the interest due hereunder been
calculated for the full term hereof at the Maximum Lawful Rate. If the Maximum
Lawful Rate is calculated pursuant to this paragraph, such interest shall be
calculated at a daily rate equal to the Maximum Lawful Rate divided by the
number of days in the year in which such calculation is made. If,
notwithstanding the provisions of this SECTION 1.2(f), a court of competent
jurisdiction shall determine by a final, non-appealable order that a Lender has
received interest hereunder in excess of the Maximum Lawful Rate, Agent shall,
to the extent permitted by applicable law, promptly apply such excess as
specified in SECTION 1.5(e) and thereafter shall refund any excess to Borrower
or as such court of competent jurisdiction may otherwise order.

                                       11

         1.3      FEES.
                  -----

                  (a) FEE LETTER. Borrower shall pay to GE Capital,
individually, the Fees specified in that certain fee letter dated as of June 27,
2006 among Borrower and GE Capital (the "GE CAPITAL FEE LETTER"), at the times
specified for payment therein.

                  (b) UNUSED LINE FEE. As additional compensation for the
Revolving Lenders, Borrower shall pay to Agent, for the ratable benefit of such
Lenders, in arrears, on the first Business Day of each month prior to the
Commitment Termination Date and on the Commitment Termination Date, a fee for
Borrower's non-use of available funds in an amount equal to the Applicable
Unused Line Fee Margin per annum multiplied by the difference between (x) the
Maximum Amount (as it may be reduced from time to time) and (y) the average for
the period of the daily closing balances of the Revolving Loan (including,
without duplication, Swing Line Loans) outstanding during the period for which
such Fee is due.

                  (c) LETTER OF CREDIT FEE. Borrower agrees to pay to Agent for
the benefit of Revolving Lenders, as compensation to such Revolving Lenders for
Letter of Credit Obligations incurred hereunder, (i) without duplication of
costs and expenses otherwise payable to Agent or Lenders hereunder, all
reasonable costs and expenses, without duplication of fees otherwise paid by
Borrower, incurred by Agent or any Lender on account of such Letter of Credit
Obligations, and (ii) for each month during which any Letter of Credit
Obligation shall remain outstanding, a fee (the "LETTER OF CREDIT FEE") in an
amount equal to the product of the average daily undrawn face amount of all
Letters of Credit issued, guaranteed or supported by risk participation
agreements multiplied by a per annum rate equal to the Applicable L/C Margin
from time to time in effect. Such fee shall be paid to Agent for the benefit of
the Revolving Lenders in arrears, on the first Business Day of each month and on
the Commitment Termination Date. In addition, Borrower shall pay to any L/C
Issuer, on demand, such reasonable fees, without duplication of fees otherwise
payable hereunder (including all per annum fees), charges and expenses of such
L/C Issuer in respect of the issuance, negotiation, acceptance, amendment,
transfer and payment of such Letter of Credit or otherwise payable pursuant to
the application and related documentation under which such Letter of Credit is
issued.

                  (d) LIBOR BREAKAGE COSTS. Upon (i) any default by Borrower in
making any borrowing of, conversion into or continuation of any LIBOR Loan
following Borrower's delivery to Agent of any LIBOR Loan request in respect
thereof or (ii) any payment of a LIBOR Loan on any day that is not the last day
of the LIBOR Period applicable thereto (regardless of the source of such
prepayment and whether voluntary, by acceleration or otherwise), Borrower shall
pay Agent, for the benefit of all Lenders that funded or were prepared to fund
any such LIBOR Loan, LIBOR Breakage Costs, if applicable.

                  (e) EXPENSES AND ATTORNEYS' FEES. Borrower agrees to pay all
reasonable, out-of-pocket fees, charges, costs and expenses (including
reasonable attorneys' fees and expenses) incurred by Agent in connection with
any matters contemplated by or arising out of the Loan Documents, in connection
with the examination, review, due diligence investigation, documentation,
negotiation, closing and syndication of the transactions contemplated herein and
in connection with the continued administration of the Loan Documents including
any amendments, modifications, consents and waivers. Borrower agrees to promptly
pay all reasonable, out-of-pocket fees, charges, costs and expenses (including


                                       12

 fees, charges, costs and expenses of attorneys, auditors, appraisers,
consultants and advisors) incurred by Agent in connection with any amendment,
waiver, consent with respect to the Loan Documents, Event of Default, work-out
or action to enforce any Loan Document or to collect any payments due from
Borrower or any other Credit Party. In addition, in connection with any work-out
or action to enforce any Loan Document or to collect any payments due from
Borrower or any other Credit Party, Borrower agrees to promptly pay all
reasonable fees, charges, costs and expenses, including, without limitation,
reasonable attorneys' fees, incurred by Lenders. All fees, charges, costs and
expenses for which Borrower is responsible under this SECTION 1.3(E) shall be
deemed part of the Obligations when incurred, payable in accordance with the
penultimate sentence of SECTION 1.4 and secured by the Collateral.

         1.4      PAYMENTS
                  --------

         All payments by Borrower of the Obligations shall be without deduction,
defense, setoff or counterclaim and shall be made in same day funds and
delivered to Agent, for the benefit of Agent and Lenders, as applicable, by wire
transfer to the account identified on ANNEX E such other place as Agent may from
time to time designate in writing.

         Borrower shall receive credit on the day of receipt for funds received
by Agent by 2:00 p.m. (New York time). In the absence of timely receipt, such
funds shall be deemed to have been paid on the next Business Day. Whenever any
payment to be made hereunder shall be stated to be due on a day that is not a
Business Day, the payment may be made on the next succeeding Business Day and
such extension of time shall be included in the computation of the amount of
interest and Fees due hereunder.

         Borrower hereby authorizes Lenders to make Revolving Credit Advances or
Swing Line Advances for the payment of Scheduled Installments, interest, Fees
and expenses, Letter of Credit reimbursement obligations and any amounts
required to be deposited with respect to outstanding Letter of Credit
Obligations pursuant to SECTIONS 1.5(f) OR 7.3; provided, that so long as no
Event of Default has occurred and is continuing, expense reimbursements pursuant
to SECTION 1.3(e) shall be payable 10 days after notice thereof to Borrower (and
otherwise such expense reimbursements shall be payable upon demand).

         1.5      PREPAYMENTS.
                  ------------

                  (a) VOLUNTARY PREPAYMENTS OF LOANS. At any time, Borrower may
prepay the Loans, in whole or in part, without premium or penalty subject to the
payment of LIBOR Breakage Costs, if applicable. Prepayments of Term Loan B shall
be applied in accordance with SECTION 1.5(e).

                  (b) PREPAYMENTS FROM EXCESS CASH FLOW. Within one hundred
(100) days after the end of each Fiscal Year commencing with the Fiscal Year
ended December 31, 2007, Borrower shall prepay the Loans in an amount equal to
seventy-five percent (75%) of the Excess Cash Flow for such Fiscal Year. The
calculation shall be based on the audited Financial Statements for Holdings and
its Subsidiaries. Any prepayments from Excess Cash Flow paid pursuant to this
SECTION 1.5(b) shall be applied in accordance with SECTION 1.5(e).

                                       13

                  (c) PREPAYMENTS FROM ASSET DISPOSITIONS. Immediately upon
receipt of any Net Proceeds in excess of $1,000,000 in the aggregate during any
Fiscal Year, Borrower shall prepay the Loans in an amount equal to such Net
Proceeds, except that Borrower or its Subsidiaries may reinvest all Net Proceeds
of any such Asset Disposition, within one hundred eighty (180) days, in fixed
assets. If Borrower does not intend to so reinvest such Net Proceeds or if the
period set forth in the immediately preceding sentence expires without Borrower
having reinvested the Net Proceeds of any such Asset Disposition, Borrower shall
prepay the Loans in an amount equal to such remaining Net Proceeds in accordance
with SECTION 1.5(e).

                  (d) PREPAYMENTS FROM ISSUANCE OF SECURITIES. Immediately upon
the receipt by Holdings, Borrower or any of its Subsidiaries of the proceeds of
the issuance of Stock, Borrower shall prepay the Loans in an amount equal to
such proceeds, net of underwriting discounts and commissions and other
reasonable out-of-pocket costs associated therewith. The payments shall be
applied in accordance with SECTION 1.5(e). Notwithstanding the foregoing, the
following proceeds of stock issuance shall be excluded from any mandatory
prepayment: (i) proceeds of issuances of Stock by Holdings or Borrower on or
prior to the Closing Date, (ii) proceeds of issuances of Stock of Holdings (and
options and warrants for the issuance of Stock of Holdings) to employees and
directors of Holdings, Borrower or Beverly and proceeds from the exercise of
options and warrants by employees and directors and (iii) proceeds of issuances
of Stock by any Subsidiary of Borrower to Borrower which constitutes an
Investment permitted hereunder.

                  (e) APPLICATION OF PROCEEDS. With respect to any prepayments
made by Borrower pursuant to SECTIONS 1.5(b), 1.5(c) and SECTION 1.5(d) and any
payments of Term Loan B pursuant to SECTION 1.5(a), such prepayments shall be
applied as follows: first, in payment of the Term Loan B in the inverse order of
maturity of the Scheduled Installments until the Term Loan B shall have been
prepaid in full; second, to any unpaid Swap Related Reimbursement Obligations
and Obligations then due and owing with respect to Interest Rate Agreements,
ratably to the aggregate combined balance of the unpaid Swap Related
Reimbursement Obligations and Obligations then due and owing with respect to
Interest Rate Agreements; third to reduce the outstanding principal balance of
the Swing Line Loan outstanding to Borrower until the same has been repaid in
full; and fourth, to the Revolving Credit Advances outstanding to Borrower until
the same has been repaid in full with a corresponding permanent reduction of the
Revolving Loan Commitment. Considering each type of Loan being prepaid
separately, any such prepayment shall be applied first to Index Rate Loans of
the type required to be prepaid before application to LIBOR Loans of the type
required to be prepaid, in each case in a manner which minimizes any resulting
LIBOR Breakage Costs.

                  (f) LETTER OF CREDIT OBLIGATIONS. In the event any Letters of
Credit are outstanding at the time that the Revolving Loan Commitment is
terminated, Borrower shall deposit with Agent for the benefit of all Revolving
Lenders cash in an amount equal to 105% of the aggregate outstanding Letter of
Credit Obligations to be available to Agent to reimburse payments of drafts
drawn under such Letters of Credit and pay any Fees and expenses related
thereto.

                                       14

                  (g) PRIMEDEX SUBORDINATED NOTES. In the event that the amount
required to redeem the Primedex Subordinated Notes (the "Required Amount") is
less than $15,626,464 (the "Target Amount"), Borrower shall, promptly upon the
redemption of the Primedex Subordinated Notes, prepay the outstanding Revolving
Credit Advances in an amount equal to the positive difference between the
Required Amount and the Target Amount (but such prepayment shall not require a
permanent reduction of the Revolving Loan Commitment).

         1.6      MATURITY.
                  ---------

         All of the Obligations shall become due and payable as otherwise set
forth herein, but in any event all of the remaining Obligations shall become due
and payable upon the Commitment Termination Date. Until the Termination Date,
Agent shall be entitled to retain the Liens on the Collateral granted under the
Collateral Documents and the ability to exercise all rights and remedies
available to them under the Loan Documents and applicable laws. Notwithstanding
anything contained in this Agreement to the contrary, upon any termination of
the Revolving Loan Commitment, all of the Obligations (other than contingent
indemnification obligations as to which no claim has been asserted) shall be due
and payable.

         1.7      LOAN ACCOUNTS.
                  --------------

         Agent shall maintain a loan account (the "LOAN ACCOUNT") on its books
to record: the name and federal employer identification number of each Lender,
all Advances and the Term Loan B, all payments made by Borrower, and all other
debits and credits as provided in this Agreement with respect to the Loans or
any other Obligations. All entries in the Loan Account shall be made in
accordance with Agent's customary accounting practices as in effect from time to
time. The balance in the Loan Account, as recorded on Agent's most recent
printout or other written statement, shall, absent manifest error, be
presumptive evidence of the amounts due and owing to Agent and Lenders by
Borrower; PROVIDED that any failure to so record or any error in so recording
shall not limit or otherwise affect (other than to the extent of such error)
Borrower's duty to pay the Obligations. Agent shall render to Borrower a monthly
accounting of transactions with respect to the Loans setting forth the balance
of the Loan Account for the immediately preceding month. Unless Borrower
notifies Agent in writing of any objection to any such accounting (specifically
describing the basis for such objection), within forty-five (45) days after the
date thereof, each and every such accounting shall, absent manifest error, be
presumptive evidence of all matters reflected therein. Only those items
expressly objected to in such notice shall be deemed to be disputed by Borrower.
Notwithstanding any provision herein contained to the contrary, any Lender may
elect (which election may be revoked) to dispense with the issuance of Notes to
that Lender and may rely on the Loan Account as evidence of the amount of
Obligations from time to time owing to it.

         1.8      YIELD PROTECTION.
                  -----------------

                  (a) CAPITAL ADEQUACY AND OTHER ADJUSTMENTS. In the event that
any Lender shall have determined that the adoption after the date hereof of any
law, treaty, governmental (or quasi-governmental) rule, regulation, guideline or
order regarding capital adequacy, reserve requirements or similar requirements
or compliance by any Lender or any corporation controlling such Lender with any
request or directive regarding capital adequacy, reserve requirements or similar
requirements (whether or not having the force of law and whether or not failure
to comply therewith would be unlawful) from any central bank or governmental
agency or body having jurisdiction does or shall have the effect of increasing


                                       15

 the amount of capital, reserves or other funds required to be maintained by such
Lender or any corporation controlling such Lender and thereby reducing the rate
of return on such Lender's or such corporation's capital as a consequence of its
obligations hereunder, then Borrower shall from time to time within fifteen (15)
days after notice and demand from such Lender (together with the certificate
referred to in the next sentence and with a copy to Agent) pay to Agent, for the
account of such Lender, additional amounts sufficient to compensate such Lender
for such reduction; provided that if the respective Lender has unreasonably
delayed or withheld such notice and demand, the respective Lender shall not be
entitled to receive additional payments pursuant to this Section 1.8(a) for
periods occurring prior to the 180th day before the receipt of such notice and
demand. A certificate as to the amount of such cost and showing the basis of the
computation of such cost submitted by such Lender to Borrower and Agent shall be
presumptive evidence of the matters set forth therein.

                  (b) INCREASED LIBOR FUNDING COSTS; ILLEGALITY. Notwithstanding
anything to the contrary contained herein, if the introduction of or any change
in any law, rule, regulation, treaty or directive (or any change in the
interpretation thereof) after the date hereof shall make it unlawful, or any
central bank or other Governmental Authority shall assert that it is unlawful,
for any Lender to agree to make or to make or to continue to fund or maintain
any LIBOR Loan, then, unless that Lender is able to make or to continue to fund
or to maintain such LIBOR Loan at another branch or office of that Lender
without, in that Lender's opinion, adversely affecting it or its Loans or the
income obtained therefrom, on notice thereof and demand therefor by such Lender
to Borrower through Agent, (i) the obligation of such Lender to agree to make or
to make or to continue to fund or maintain LIBOR Loans shall terminate and (ii)
Borrower shall forthwith prepay in full each such outstanding LIBOR Loans owing
to such Lender, together with interest accrued thereon, unless Borrower, within
five (5) Business Days after the delivery of such notice and demand, converts
all LIBOR Loans into Index Rate Loans. If, after the date hereof, the
introduction of, change in or interpretation of any law, rule, regulation,
treaty or directive would impose or increase reserve requirements (other than as
taken into account in the definition of LIBOR) and the result of any of the
foregoing is to increase the cost to Agent or any such Lender of issuing any
Letter of Credit or making or continuing any Loan hereunder, as the case may be,
or to reduce any amount receivable hereunder, then Borrower shall from time to
time within fifteen (15) days after notice and demand from Agent (together with
the certificate referred to in the next sentence) pay to Agent for the account
of all such affected Lenders additional amounts sufficient to compensate such
Lenders for such increased cost; provided that Borrower shall not be liable to
pay for any such amounts incurred or accrued more than one hundred eighty (180)
days prior to the date on which notice of the event giving rise to the
obligation to make such payment is given to Borrower, and provided further, that
such Lender shall not be entitled to any such additional amounts unless such
Lender is imposing similar types of assessments on other similarly situated
borrowers. A certificate as to the amount of such cost and showing the basis of
the computation of such cost submitted by Agent on behalf of all such affected
Lenders to Borrower shall be presumptive evidence of the matters set forth
therein.

         1.9      TAXES.
                  ------

                  (a) NO DEDUCTIONS; OTHER TAXES. Any and all payments or
reimbursements made hereunder or under any other Loan Documents shall be made
free and clear of and without deduction for any and all Charges, present or


                                       16

 future, taxes, levies, imposts, deductions or withholdings, and all liabilities
with respect thereto (including any interest, additions to tax or penalties
applicable thereto) of any nature whatsoever imposed by any Governmental
Authority ("TAXES"), excluding (a) such Taxes to the extent imposed on or
measured by Agent's or a Lender's net income (and franchise taxes, branch
profits taxes, taxes on doing business or other taxes imposed in lieu thereof)
as a result of a connection between such Agent or Lender and the jurisdiction of
the Governmental Authority imposing such Tax or any political subdivision or
taxing authority thereof or therein (other than any such connection that would
not have arisen but for such Agent or Lender having executed, delivered,
performed its obligations or received a payment under, or enforced, this
Agreement or any other Loan Document) and (b) any United States federal
withholding tax that is imposed on amounts payable to a Foreign Lender at the
time such Foreign Lender becomes a party to this Agreement or is attributable to
such Foreign Lender's failure (other than as a result of a change in law, rule,
regulation or treaty or in the administration, interpretation or application
thereof by any Governmental Authority) to comply with SECTION 1.9(c), except to
the extent that such Foreign Lender's assignor (if any) was entitled, at the
time of assignment, to receive additional amounts from the Borrower with respect
to such withholding tax pursuant to this SECTION 1.9(a) (collectively, "EXCLUDED
Taxes," and all such non-Excluded Taxes being referred to herein as
"NON-EXCLUDED TAXES"). If Borrower shall be required by law to deduct any
Non-Excluded Taxes or Other Taxes from or in respect of any sum payable
hereunder or under any other Loan Document to any Lender or Agent, then the sum
payable hereunder shall be increased as may be necessary so that, after making
all required deductions (including deductions applicable to additional sums
payable pursuant to this SECTION 1.9), such Lender or Agent receives an amount
equal to the sum it would have received had no such deductions been made. If any
amounts are payable in respect of Non-Excluded Taxes or Other Taxes pursuant to
the preceding sentence, Borrower agrees to reimburse each Lender or Agent, upon
the written request of such Lender or Agent and reasonable documentation of such
amounts, for any net additional taxes imposed on or measured by the net income
of such Lender or Agent as such Lender or Agent shall determine are payable in
respect of such amounts so paid to or on behalf of such Lender or Agent pursuant
to the preceding sentence and in respect of any amounts paid to or on behalf of
such Lender or Agent pursuant to this sentence. All required deductions shall be
withheld and timely paid over to the relevant Governmental Authority in
accordance with applicable law. In addition, Borrower agrees to timely pay to
the relevant Governmental Authority in accordance with applicable law any
present or future stamp or documentary taxes or any other excise or property
taxes, charges or similar levies which arise from any payment made hereunder or
under any other Loan Document or from the execution, delivery, enforcement or
registration of, or otherwise with respect to, this Agreement or any other Loan
Document ("OTHER TAXES").

                  (b) CHANGES IN TAX LAWS. In the event that, after the date
hereof (or in the case of an assignee or participant, the date of the relevant
assignment or sale of a participation), (1) any changes in any existing law,
regulation, treaty or directive or in the administration, interpretation or
application thereof, (2) any new law, regulation, treaty or directive enacted or
any administration, interpretation or application thereof, or (3) compliance
with any request, guideline or directive (whether or not having the force of
law) from any Governmental Authority:

                                       17

                           (i) does or shall subject Agent or any Lender to any
tax of any kind whatsoever with respect to this Agreement, or any other Loan
Documents or any Loans made or Letters of Credit issued hereunder, or change the
basis of taxation of payments to Agent or such Lender in respect thereof (except
for the imposition of, or any change in the rate of, any Excluded Tax); or

                           (ii) does or shall impose on Agent or any Lender any
other condition, cost or expense in connection with the transactions
contemplated hereby or participations herein; and the result of any of the
foregoing is to increase the cost to Agent or any such Lender of issuing or
maintaining any Letter of Credit or making or continuing any Loan hereunder, as
the case may be, or to reduce any amount receivable hereunder or under any other
Loan Document, then, in any such case, Borrower shall promptly pay to Agent or
such Lender, upon its demand with reasonable documentation thereof, any
additional amounts necessary to compensate Agent or such Lender, on an after-tax
basis, for such additional cost or reduced amount receivable, as reasonably
determined by Agent or such Lender; provided that Agent or such Lender shall not
be entitled to any such amounts to the extent that the event giving rise to such
additional cost or reduced amount receivable occurred more than 180 days prior
to the date such notice and demand is given to the Borrower; provided, however,
that if the event giving rise to such additional cost or reduced amount
receivable has a retroactive effect, then such 180-day period shall be extended
to include the period of such retroactive effect. If Agent or such Lender
becomes aware that it is entitled to claim any additional amounts pursuant to
this SECTION 1.9(b), it shall promptly notify Borrower of the event by reason of
which Agent or such Lender has become so entitled. A certificate as to any
additional amounts payable pursuant to the foregoing sentence submitted by Agent
or such Lender to Borrower (with a copy to Agent if applicable) shall be
presumptive evidence of the amount due. Borrower shall be presumptive evidence
of the amount due. Borrower shall pay Agent or such Lender, as the case may be,
the amount shown as due on any such certificate within ten (10) days after the
receipt thereof.

                  (c) FOREIGN LENDERS. Prior to becoming a Lender under this
Agreement and within fifteen (15) days after a reasonable written request of
Borrower or Agent from time to time thereafter, each such Person or Lender that
is not in each case a "United States person" (as such term is defined in IRC
Section 7701(a)(30)) for U.S. federal income tax purposes (a "FOREIGN LENDER")
shall provide to Borrower and Agent, if it is legally entitled to, a properly
completed and executed IRS Form W-8BEN or Form W-8ECI or other applicable form,
certificate or document prescribed by the IRS, certifying as to such Foreign
Lender's entitlement to an exemption from, or reduction in, United States
withholding tax with respect to payments to be made to such Foreign Lender under
this Agreement and under the Notes (a "CERTIFICATE OF EXEMPTION").

                  (d) INDEMNIFICATION. Borrower will indemnify each Lender and
Agent for the full amount of Non-Excluded Taxes and Other Taxes (including any
Non-Excluded Taxes and Other Taxes imposed by any jurisdiction on amounts
payable under this SECTION 1.9) paid by such Lender or Agent, as the case may
be, and any liability (including penalties, interest and expenses including
reasonable attorney's fees and expenses) arising therefrom or with respect
thereto, whether or not such Non-Excluded Taxes or Other Taxes were correctly or
legally asserted by the relevant Governmental Authority. A certificate as to the


                                       18

 amount of such payments or liabilities submitted by Lender or Agent to Borrower
(with a copy to Agent if applicable) shall be presumptive evidence of the amount
due. Borrower shall pay Agent or such Lender, as the case may be, the amount
shown as due on any such certificate within ten (10) day s after the receipt
thereof.

                  (e) EVIDENCE OF PAYMENTS. As soon as practicable after any
payment of Non-Excluded Taxes or Other Taxes by the Borrower to a Governmental
Authority, the Borrower shall deliver to the Agent the original or a certified
copy of a receipt issued by such Governmental Authority evidencing such payment,
a copy of the return reporting such payment or other evidence of such payment
reasonably satisfactory to the Agent.

                                   SECTION 2.
                               CONDITIONS TO LOANS
                               -------------------

         The obligations of Lenders and L/C Issuers to make Loans and to issue
or cause to be issued Letters of Credit are subject to satisfaction of all of
the applicable conditions set forth below.

         2.1      CONDITIONS TO INITIAL LOANS.
                  ----------------------------

         The obligations of Lenders and L/C Issuers to make the initial Loans
and to issue or cause to be issued Letters of Credit on the Closing Date are, in
addition to the conditions precedent specified in SECTION 2.2, subject to

                  (a) the Second Lien Loans shall have been, or shall reasonably
concurrently be, fully funded in an aggregate principal amount not to exceed
$135,000,000. The terms and conditions of the Second Lien Loans shall be
reasonably satisfactory in form and substance to the Agent and each Lender;

copy of the three most recent form IRS/DOL 5500-series for each such Plan, to
the extent applicable, have been delivered to Agent. Except with respect to
Multiemployer Plans, each Qualified Plan has been determined by the IRS to
qualify under Section 401(a) of the IRC, and to the knowledge of the applicable
Credit Party, nothing has occurred that would cause the loss of such
qualification. Except as would not reasonably be expected to have a Material


                                       26

 Adverse Effect, each Plan is in material compliance with the applicable
provisions of ERISA and the IRC. Neither any Credit Party nor ERISA Affiliate
has failed to make any contribution or pay any amount due as required by either
Section 412 of the IRC or Section 302 of ERISA or the terms of any Title IV
Plan. No Credit Party has engaged in a "prohibited transaction," as defined in

that would subject any Credit Party to a material tax on prohibited transactions
imposed by Section 502(i) of ERISA or Section 4975 of the IRC.

for benefits in the normal course), sanctions, actions or lawsuits, asserted or
instituted against any Plan or any Person as fiduciary or sponsor of any Plan
that could result in liability to a Credit Party; (iv) within the last five
years no Title IV Plan of any Credit Party or ERISA Affiliate has been
terminated, whether or not in a "standard termination" as that term is used in
Section 404(b)(1) of ERISA, that remains unsatisfied or could reasonably be
expected to result in liability to any Credit Party in excess of $500,000, nor
has any Title IV Plan of any Credit Party or ERISA Affiliate (determined at any
time within the past five years) with Unfunded Pension Liabilities been
transferred outside of the "controlled group" (within the meaning of Section
4001(a)(14) of ERISA) of any Credit Party or ERISA Affiliate that has or could
reasonably be expected to result in a Material Adverse Effect.

Party, other than guaranties issued by Holdings or Borrower of leases for leased
premises of any Credit Party, and any Lien granted by such Credit Party with
respect thereto which are to remain in effect after the Closing Date; and
instruments and agreements evidencing the issuance of any equity securities,
warrants, rights or options to purchase equity securities of such Credit Party.

                                       27

         3.19     INSURANCE.
                  ----------

         Each Credit Party represents and warrants that it and each of its
Subsidiaries currently maintains in good repair, working order and condition
(normal wear and tear excepted) all material properties as set forth in SECTION
4.2 and maintains all insurance described in such SECTION. SCHEDULE 3.19 lists
all insurance policies of any nature maintained, as of the Closing Date, for
current occurrences by each Credit Party, as well as a summary of the key
business terms of each such policy such as deductibles, coverage limits and term
of policy.

         3.20     TAXES AND TAX RETURNS.
                  ----------------------

                  (a) As of the Closing Date, (i) all Tax Returns required to be
filed by the Credit Parties have been timely and properly filed and (ii) all
taxes that are due (other than taxes being contested in good faith by
appropriate proceedings and for which adequate reserves have been provided for
in accordance with GAAP) have been paid, in each case except where the failure
to file Tax Returns or pay Taxes would not reasonably be expected to have a
Material Adverse Effect. No Governmental Authority has asserted any claim for
taxes, or to any Credit Party's knowledge, has threatened to assert any claim
for taxes that would, if not paid by a Credit Party, have a Material Adverse
Effect. All taxes required by law to be withheld or collected and remitted
(including, without limitation, income tax, unemployment insurance and workmen's
compensation premiums) with respect to the Credit Parties have been withheld or
collected and paid to the appropriate Governmental Authorities (or are properly
being held for such payment), except for amounts the nonpayment of which would
not be reasonably likely to have a Material Adverse Effect.

                  (b) None of the Credit Parties has been notified that either
the IRS, or any other Governmental Authority, has raised or intends to raise,
any adjustments with respect to Taxes of the Credit Parties, which adjustments
would be reasonably likely to have a Material Adverse Effect.

         3.21     INACTIVE SUBSIDIARIES.
                  ----------------------

         No Inactive Subsidiary (i) engages in any trade or business or owns any
assets (other than Stock of their respective Subsidiaries) with a fair market
value in the aggregate in excess of $10,000 or (ii) has outstanding or incurred
any Indebtedness or Guaranteed Indebtedness.

         3.22     HEALTH CARE MATTERS.
                  --------------------

                  (a) COMPLIANCE WITH HEALTH CARE LAWS; PERMITS. Each Credit
Party and each of their Subsidiaries, and any Person acting on their behalf, is
in compliance in all material respects with all Health Care Laws applicable to
it, its products and its properties or other assets or its business or
operation, including its provision of professional services. Each Credit Party
and each of their Subsidiaries, and any Person acting on their behalf, has in
effect all Permits, including, without limitation, all Permits necessary for it
to own, lease or operate its properties and other assets and to carry on its
business and operations, including its provision of professional services, as
presently conducted. All such Permits are in full force and effect and there has
occurred no default under, or violation of, any such Permit. Except as set forth
on SCHEDULE 3.22, no action, demand, requirement or investigation by any


                                       28

 Governmental Authority and no suit, action or proceeding by any other person, in
each case with respect to each Credit Party, each of their Subsidiaries, any
Person acting on their behalf, or any of their respective properties, other
assets or provision of professional services under any Requirements of Law, is
pending or, to the knowledge of each Credit Party and their Subsidiaries,
threatened.

                  (b) FILINGS. Except as set forth on SCHEDULE 3.22, all
reports, documents, claims, notices or approvals required to be filed, obtained,
maintained or furnished to any Governmental Authority have been so filed,
obtained, maintained or furnished, and all such reports, documents, claims and
notices were complete and correct in all material respects on the date filed (or
were corrected in or supplemented by a subsequent filing).

                  (c) MATERIAL STATEMENTS. No Credit Party nor any of their
Subsidiaries, nor any officer, affiliate, employee or agent of any Credit Party
or any of their Subsidiaries, has made an untrue statement of a material fact or
fraudulent statement to any Governmental Authority, failed to disclose a
material fact required to any Governmental Authority, or committed an act, made
a statement, or failed to make a statement that, at the time such disclosure was
made, would reasonably be expected to constitute a violation of any Health Care
Law. No Credit Party nor any of their Subsidiaries, nor any officer, affiliate,
employee or agent of any Credit Party or any of their Subsidiaries, has made any
untrue statement of fact regarding claims incurred but not reported.

                  (d) BILLING. Each Credit Party, each of their Subsidiaries and
each contracting physician of each Credit Party or any of their Subsidiaries (to
the extent required) has the requisite provider number or other Permit to bill
the Medicare program (to the extent such entity participates in the Medicare
program), the respective Medicaid program in the state or states in which such
entity operates, and all other Third Party Payor Programs (as defined below),
including but not limited to Capitated Contracts with managed care
organizations, that each Credit Party and each of their Subsidiaries currently
bill. There is no investigation, audit, claim review, or other action pending,
or to the knowledge of any Credit Party or their Subsidiaries, threatened which
could result in a revocation, suspension, termination, probation, restriction,
limitation, or non-renewal of any Third Party Payor (as defined below) provider
number or result in any Credit Party's or any of their Subsidiaries' exclusion
from any Third Party Payor Program. No Credit Party nor any of their
Subsidiaries has billed or received any payment or reimbursement in excess of
amounts allowed by any Health Care Law or other law. For purposes of this
Agreement, a "THIRD PARTY PAYOR" means Medicare, Medicaid, TRICARE, Blue Cross
and/or Blue Shield, state government insurers, private insurers and any other
person or entity which presently or in the future maintains Third Party Payor
Programs. In addition, for purposes of this Agreement, "THIRD PARTY PAYOR
PROGRAMS" means all third party payor programs in which Borrower, each of the
Credit Parties and each of its Subsidiaries participates (including, without
limitation, Medicare, Medicaid, TRICARE or any other federal or state health
care programs, as well as Blue Cross and/or Blue Shield, managed care plans, or
any other private insurance programs).

                  (e) PROCEEDINGS. There are no facts, circumstances or
conditions that would reasonably be expected to form the basis for any material
investigation, suit, claim, audit, action (legal or regulatory) or proceeding
(legal or regulatory) by a Governmental Authority against or affecting any
Credit Party or any of their Subsidiaries relating to any of the Health Care
Laws.

                                       29

                  (f) PROHIBITED TRANSACTIONS. No Credit Party, any of their
Subsidiaries or any Person acting on behalf of any Credit Party or any of their
Subsidiaries is a party to any contract, lease agreement or other arrangement
(including any joint venture, service or consulting agreement) with any
physician, physician group, health care facility, hospital, nursing facility,
home health agency or other person who is in a position to make or influence
referrals to or otherwise generate business to provide services, lease space,
lease equipment or engage in any other venture or activity, other than
agreements which are in compliance with all applicable Health Care Laws. No
Credit Party, any of their Subsidiaries, or any person acting on behalf of any
Credit Parties or any their Subsidiaries, directly or indirectly: (1) offered or
paid any remuneration, in cash or in kind, to, or made any financial
arrangements with, any past, present or potential patient, supplier, medical
staff member, contractor or Third Party Payor of any Credit Parties and/or any
of their Subsidiaries in order to illegally obtain business or payments from
such person; (2) given or agreed to give, or is aware that there has been made
or that there is any illegal agreement to make, any illegal gift or gratuitous
payment of any kind, nature or description (whether in money, property or
services) to any past, present or potential patient, supplier, contractor, Third
Party Payor or any other person; (3) made or agreed to make, or is aware that
there has been made or that there is any agreement to make, any contribution,
payment or gift of funds or property to, or for the private use of, any
governmental official, employee or agent where either the contribution, payment
or gift or the purpose of such contribution, payment or gift is or was illegal
under the laws of any government entity having jurisdiction over such payment,
contribution or gift; (4) established or maintained any unrecorded fund or asset
for any purpose or made any misleading, false or artificial entries on any of
its books or records for any reason; or (5) made, or agreed to make, or is aware
that there has been made or that there is any agreement to make, any payment to
any person with the intention or understanding that any part of such payment
would be used or was given for any purpose other than that described in the
documents supporting such payment.

                  (g) FAIR MARKET VALUE. The compensation paid or to be paid by
each Credit Party and each of their Subsidiaries to any physician or physician
group who is employed by or contracted with each Credit Party or any of their
Subsidiaries is fair market value for the services and items actually provided
by such physician, not taking into account the value or volume of referrals or
other business generated by such physicians or physician groups for each Credit
Party or each of their Subsidiaries. Each Credit Party and each of their
Subsidiaries has at all times maintained a written agreement with each physician
or physician group receiving compensation from each Credit Party or any of their
Subsidiaries.

                  (h) MEDICARE/MEDICAID. There are no Medicare or Medicaid
termination proceedings underway with respect to any of the Credit Parties, each
entity meets the Medicare conditions of participation and, to our knowledge
after such reasonable investigation under the circumstances, no employee or
independent contractor of any Credit Parties has been excluded in participating
in Medicare or Medicaid or any similar federal programs.

                  (i) COMPLIANCE. Each Credit Parties possess and implement all
necessary policies and procedures to ensure that all aspects of each Credit
Parties' operations, their employees, and all healthcare providers under
contract with any Credit Party, comply with all applicable Health Care Laws.

                                       30

                  (j) CORPORATE INTEGRITY AGREEMENTS, ETC. No Credit Party, nor
any of their Subsidiaries, is a party to any corporate integrity agreements,
monitoring agreements, consent decrees, settlement orders, or similar agreement
with or imposed by any Governmental Authority.

         3.23     MERGER AGREEMENT.
                  -----------------

         As of the Closing Date, Borrower has delivered to Agent a complete and
correct copy of the Merger Agreement (including all schedules, exhibits,
amendments, supplements, modifications, assignments and all other documents
delivered pursuant thereto or in connection therewith). No Credit Party, and to
the knowledge of any Credit Party, no other Person party thereto is in material
default in the performance or compliance with any provisions thereof. The Merger
Agreement complies with, in all material respects, and the Acquisition has been
consummated in accordance with all applicable laws. All covenants and conditions

other documents delivered pursuant thereto or in connection therewith) have been

force and effect as of the Closing Date and has not been terminated, rescinded
or withdrawn. All material approvals by Governmental Authorities having
jurisdiction over any Credit Party and other Persons referenced therein, with
respect to the transactions contemplated by the Merger Agreement, have been
obtained, and no such approvals impose any conditions to the consummation of the
transactions contemplated by the Merger Agreement or to the conduct by any
Credit Party of its business thereafter. To Borrower's actual knowledge, the
Radiologix's representations and warranties in the Merger Agreement are not
untrue or misleading in any material respect.

         3.24     NO EARN-OUTS.
                  -------------

         No "earn-outs" or any similar payment obligations are payable by any
Credit Party or any of their respective Subsidiaries in connection with the
Acquisition or any transaction occurring in connection therewith.

                                   SECTION 4.
                              AFFIRMATIVE COVENANTS
                              ---------------------

         Each Credit Party executing this Agreement jointly and severally agrees
as to all Credit Parties that from and after the date hereof and until the
Termination Date:

         4.1      COMPLIANCE WITH LAWS AND CONTRACTUAL OBLIGATIONS.
                  -------------------------------------------------

         Each Credit Party will (a) comply with and shall cause each of its
Subsidiaries to comply with (i) the requirements of all applicable material
laws, rules, regulations and orders of any Governmental Authority (including,
without limitation, laws, rules, regulations and orders relating to taxes,
employer and employee contributions, securities, employee retirement and welfare
benefits, environmental protection matters and employee health and safety) as
now in effect and which may be imposed in the future in all jurisdictions in
which any Credit Party or any of its Subsidiaries is now doing business or may
hereafter be doing business and (ii) the obligations, covenants and conditions


                                       31

 contained in all Contractual Obligations of such Credit Party or any of its
Subsidiaries other than the noncompliance with which would not be reasonably
expected to have, either individually or in the aggregate, a Material Adverse
Effect, and (b) maintain or obtain and shall cause each of its Subsidiaries to
maintain or obtain all licenses, qualifications and permits now held or
hereafter required to be held by such Credit Party or any of its Subsidiaries,
for which the loss, suspension, revocation or failure to obtain or renew, would
reasonably be expected to have, either individually or in the aggregate, a
Material Adverse Effect. This SECTION 4.1 shall not preclude any Credit Party or
its Subsidiaries from contesting any taxes or other payments, if they are being
diligently contested in good faith in a manner which stays enforcement thereof
and if appropriate expense provisions have been recorded in conformity with
GAAP, subject to SECTION 5.2 and no Lien (other than a Permitted Encumbrance) in
respect thereof has been created.

         4.2      INSURANCE.
                  ----------

         Each Credit Party will maintain or cause to be maintained, with
insurers reasonably acceptable to Agent, public liability and property damage
insurance with respect to its business and properties and the business and
properties of its Subsidiaries against loss or damage of the kinds customarily
carried or maintained by corporations of established reputation engaged in
substantially similar businesses and in amounts reasonably acceptable to Agent
and will deliver evidence thereof to Agent. Agent confirms that the insurance in
effect on the Closing Date is reasonably acceptable to it. The Credit Parties
shall maintain business interruption insurance providing coverage for a period
of at least six (6) months and in an amount not less than $30,000,000. Each
Credit Party shall, pursuant to endorsements and/or assignments in form and
substance reasonably satisfactory to Agent, (i) cause Agent to be named as
lender's loss payee in the case of casualty insurance, and assignee in the case
of all business interruption insurance, in each case for the benefit of Agent
and Lenders and (ii) cause Agent and each Lender to be named as additional
insureds in the case of all liability insurance other than professional
liability insurance. So long as no Event of Default has occurred and is
continuing, proceeds of business interruption insurance will be released to the
Credit Parties. In the event any Credit Party fails to provide Agent with
evidence of the insurance coverage required by this Agreement, Agent may
purchase insurance at such Credit Party's expense to protect Agent's interests
in the Collateral. This insurance may, but need not, protect such Credit Party's
interests. The coverage purchased by Agent may not pay any claim made by such
Credit Party or any claim that is made against such Credit Party in connection
with the Collateral. Such Credit Party may later cancel any insurance purchased
by Agent, but only after providing Agent with evidence that such Credit Party
has obtained insurance as required by this Agreement. If Agent purchases
insurance for the Collateral, such Credit Party will be responsible for the
costs of that insurance, including interest and other Charges imposed by Agent
in connection with the placement of the insurance, until the effective date of
the cancellation or expiration of the insurance. The costs of the insurance may
be added to the Obligations. The costs of the insurance may be more than the
cost of insurance such Credit Party is able to obtain on its own.

         4.3      INSPECTION; LENDER MEETING.
                  ---------------------------

         Upon three (3) days' prior written notice to the Credit Parties and the
Lenders, each Credit Party shall permit any authorized representatives of Agent
to visit, audit and inspect any of the properties of such Credit Party and its


                                       32

 Subsidiaries, including its and their financial and accounting records (which
audits and inspections of financial and accounting records shall in the absence
of an Event of Default take place in Borrower's corporate office), and to make
copies and take extracts therefrom, and to discuss its and their affairs,
finances and business with its and their officers and certified public
accountants, at such reasonable times during normal business hours and as often
as may be reasonably requested (collectively a "FIELD REVIEW"); provided, that,
upon the occurrence and continuance of an Event of Default, Agent shall not be
required to provide any notice to the Credit Parties prior to the performance of
a Field Review; provided further, that, so long as no Event of Default has
occurred and is continuing, Agent shall be limited to two (2) Field Reviews
during any calendar year. Representatives of each Lender will be permitted to
accompany representatives of Agent during each Field Review at such Lender's
expense. In addition to the foregoing, each Credit Party will participate and
will cause key management personnel of each Credit Party and its Subsidiaries to
participate in a meeting with Agent and Lenders at least once during each year,
which meeting shall be held at such time and such place as may be reasonably
requested by Agent.

         4.4      ORGANIZATIONAL EXISTENCE.
                  -------------------------

         Except as otherwise permitted by SECTION 5.6, each Credit Party will
and will cause its material Subsidiaries to at all times preserve and keep in
full force and effect its organizational existence and all rights and franchises
material to its business.

         4.5      ENVIRONMENTAL MATTERS.
                  ----------------------

         Each Credit Party shall and shall cause each Person within its control
to: (a) conduct its operations and keep and maintain its Real Estate in
compliance with all Environmental Laws and Environmental Permits other than
noncompliance that would not reasonably be expected to have a Material Adverse
Effect; (b) implement any and all investigation, remediation, removal and
response actions that are appropriate or necessary to maintain the value and
marketability of the Real Estate or to otherwise comply with Environmental Laws
and Environmental Permits pertaining to the presence, generation, treatment,
storage, use, disposal, transportation or Release of any Hazardous Material on,
at, in, under, above, to, from or about any of its Real Estate, except where the
failure to do so would not reasonably be expected to have, either individually
or in the aggregate, a Material Adverse Effect; (c) notify Agent promptly after
such Credit Party or any Person within its control becomes aware of any
violation of Environmental Laws or Environmental Permits or any Release on, at,
in, under, above, to, from or about any Real Estate that is reasonably likely to
result in Environmental Liabilities to a Credit Party or its Subsidiaries in
excess of $100,000; and (d) promptly forward to Agent a copy of any order,
notice of actual or alleged violation or liability, request for information or
any communication or report received by such Credit Party or any Person within
its control in connection with any such violation or Release or any other matter
relating to any Environmental Laws or Environmental Permits that could
reasonably be expected to result in Environmental Liabilities in excess of
$100,000, in each case whether or not the Environmental Protection Agency or any
Governmental Authority has taken or threatened any action in connection with any
such violation, Release or other matter. If Agent at any time has a reasonable
basis to believe that there may be a violation of any Environmental Laws or
Environmental Permits by any Credit Party or any Person under its control or any
Environmental Liability arising thereunder, or a Release of Hazardous Materials
on, at, in, under, above, to, from or about any of its Real Estate, that, in


                                       33

 each case, could reasonably be expected to have a Material Adverse Effect, then
each Credit Party and its Subsidiaries shall, upon Agent's written request (i)
cause the performance of such environmental audits including subsurface sampling
of soil and groundwater, and preparation of such environmental reports, at
Borrower's expense, as Agent may from time to time reasonably request, which
shall be conducted by reputable environmental consulting firms reasonably
acceptable to Agent and shall be in form and substance reasonably acceptable to
Agent, and (ii) if the Credit Parties fail to perform (or cause performance of)
any environmental audit under SECTION 4.5(d)(i) above within a reasonable time
after receiving a written request from Agent, Credit Parties shall permit Agent
or its representatives to have reasonable access to all Real Estate for the
purpose of conducting such environmental audits and testing as Agent deems
appropriate, including subsurface sampling of soil and groundwater. Borrower
shall reimburse Agent for the costs of such audits and tests and the same will
constitute a part of the Obligations. Agent confirms that the environmental
reports provided on or before the Closing Date are satisfactory to it.

         4.6      LANDLORDS' AGREEMENTS, MORTGAGEE AGREEMENTS, BAILEE LETTERS
                  -----------------------------------------------------------
                  AND REAL ESTATE PURCHASES.
                  --------------------------

         Each Credit Party shall use reasonable efforts to obtain a landlord's
agreement, mortgagee agreement or bailee letter, as applicable, from the lessor
of Borrower's corporate office, which agreement or letter shall contain a waiver
or subordination of all Liens or claims that the landlord, mortgagee or bailee
may assert against the Collateral at that location, and shall otherwise be
reasonably satisfactory in form and substance to Agent. Each Credit Party shall
and shall cause its Subsidiaries to timely and fully pay and perform their
obligations under all leases and other agreements with respect to each leased
location or public warehouse where any Collateral is or may be located (other
than Collateral in an aggregate amount for all such locations not to exceed
$100,000 in the aggregate).

         4.7      FURTHER ASSURANCES.
                  -------------------

                  (a) Each Credit Party shall, from time to time, execute such
guaranties, financing statements, documents, security agreements and reports as
Agent or Requisite Lenders at any time may reasonably request to evidence,
perfect or otherwise implement the guaranties and security for repayment of the
Obligations contemplated by the Loan Documents.

                  (b) In the event any Credit Party acquires a fee ownership
interest in real property after the Closing Date, such Credit Party shall
deliver to Agent a fully executed mortgage or deed of trust over such real
property in form and substance reasonably satisfactory to Agent, together with
such title insurance policies, surveys, appraisals, evidence of insurance, legal
opinions, environmental assessments and other documents and certificates as
shall be reasonably required by Agent.

                  (c) Each Credit Party shall (i) cause each Person (other than
Inactive Subsidiaries), upon its becoming a Domestic Subsidiary of such Credit
Party (provided that this shall not be construed to constitute consent by any of
the Lenders to any transaction not expressly permitted by the terms of this
Agreement), promptly to guaranty the Obligations and to grant to Agent, for the
benefit of Agent and Lenders, a security interest in the real, personal and
mixed property of such Domestic Subsidiary to secure the Obligations and (ii)


                                       34

 pledge, or cause to be pledged, to Agent, for the benefit of Agent and Lenders,
all of the Stock of such Domestic Subsidiary to secure the Obligations. Each
Credit Party shall pledge, or cause to be pledged, to Agent, for the benefit of
Agent and Lenders, 66% of the outstanding voting Stock and 100% of the
outstanding nonvoting Stock of any person upon its becoming a first tier Foreign
Subsidiary of any Credit Party. The documentation for such guaranty, security
and pledge shall be substantially similar to the Loan Documents executed
concurrently herewith with such modifications as are reasonably requested by
Agent.

         4.8      PAYMENT OF TAXES.
                  -----------------

         Each Credit Party shall timely pay and discharge (or cause to be paid
and discharged) all material taxes, assessments and governmental and other
charges or levies imposed upon it or upon its income or profits, or upon
property belonging to it; provided that such Credit Party shall not be required
to pay any such tax, assessment, charge or levy that is being contested in good
faith by appropriate proceedings and for which the affected Credit Party shall
have set aside on its books adequate reserves with respect thereto in
conformance with GAAP.

         4.9      CASH MANAGEMENT SYSTEMS.
                  ------------------------

         Borrower shall, and shall cause each other Credit Party to, enter into
Control Agreements with respect to each deposit account maintained by Borrower
or any Subsidiary of Borrower (other than any payroll account or other
disbursement account which is a zero balance account) as of or after the Closing
Date. Each such deposit account control agreement shall be in form and substance
reasonably satisfactory to Agent. The Credit Parties shall, on or prior to
December 31, 2006, close each bank account marked by an asterisk on SCHEDULE

rights and remedies with respect to Borrower prior to such Permitted
Acquisition;

         (iii) such Permitted Acquisition shall be consensual and shall have

Holdings and its Subsidiaries for the four quarter period ending on the last day
of the month immediately preceding the month in which such proposed Permitted
Acquisition is to be consummated (after giving effect to such Permitted
Acquisition and all Loans funded in connection therewith as if made on the first
day such period); in each case to the extent no Default or Event of Default has
occurred and is continuing or would result after giving effect to such Permitted
Acquisition;

         (v) the sum of all amounts payable in connection with any Permitted
Acquisition (including the purchase price, all transaction costs and all

$16,000,000;

year and its most recent interim financial period completed within sixty (60)
days prior to the date of consummation of such Permitted Acquisition;

         (vii) the business and assets acquired in such Permitted Acquisition
shall be free and clear of all Liens (other than Permitted Encumbrances);

therewith, and such Acquisition Pro Forma shall reflect that (x) on a pro forma
basis, Holdings and its Subsidiaries would have had a Leverage Ratio and Senior
Leverage Ratio with a numerator (or equivalent thereof) one quarter (0.25) less
than otherwise permitted (for example, if the permitted Leverage Ratio is less
than or equal 3.00 to 1.00, Holdings and its Subsidiaries must have a Leverage
Ratio of less than or equal to 2.75 to 1.00) for the four quarter period ending
on the last day of the month immediately preceding the month in which such
proposed Permitted Acquisition is to be consummated (after giving effect to such
Permitted Acquisition and all Loans funded in connection therewith as if made on
the first day of such period), (y) average daily Borrowing Availability for the
90-day period preceding the consummation of such Permitted Acquisition would
have exceeded $10,000,000 on a pro forma basis (after giving effect to such
Permitted Acquisition and all Loans funded in connection therewith as if made on
the first day of such period) and the Acquisition Projections (as hereinafter
defined) shall reflect that such Borrowing Availability of $10,000,000 shall
continue for at least 90 days after the consummation of such Permitted
Acquisition, and (z) on a pro forma basis, no Event of Default has occurred and
is continuing or would result after giving effect to such Permitted Acquisition

Excess Cash Flow Certificate most recently delivered to Agent pursuant to
SECTION 6.2(o) prior to the consummation of such Permitted Acquisition (after
giving effect to such Permitted Acquisition and all Loans funded in connection
therewith as if made on the first day of such period);

                           (B) updated versions of the most recently delivered
Projections covering the 3 year period commencing on the date of such Permitted


                                       43

 Acquisition and otherwise prepared in accordance with the Projections (the
"ACQUISITION PROJECTIONS") and based upon historical financial data of a recent
date reasonably satisfactory to Agent, taking into account such Permitted
Acquisition; and

                           (C) a certificate of the chief financial officer of
Borrower to the effect that: (w) Borrower (after taking into consideration all
rights of contribution and indemnity Borrower has against Holdings and each
other Subsidiary of Holdings) will be Solvent upon the consummation of the
Permitted Acquisition; (x) the Acquisition Pro Forma fairly presents the
financial condition of Holdings and its Subsidiaries (on a consolidated basis)
as of the date thereof after giving effect to the Permitted Acquisition; (y) the
Acquisition Projections are reasonable estimates of the future financial
performance of Holdings and its Subsidiaries subsequent to the date thereof
based upon the historical performance of Holdings and its Subsidiaries and the
Target and show that Holdings and its Subsidiaries shall continue to be in
compliance with the financial covenants set forth in SECTION 6 for the 3-year
period thereafter; and (z) Holdings and its Subsidiaries have completed their
due diligence investigation with respect to the Target and such Permitted
Acquisition, which investigation was conducted in a manner similar to that which
would have been conducted by a prudent purchaser of a comparable business and
the results of which investigation were delivered to Agent and Lenders;

         (x) on or prior to the date of such Permitted Acquisition, Agent shall
have received, in form and substance reasonably satisfactory to Agent, copies of
the acquisition agreement and related agreements and instruments, and all
opinions, certificates, lien search results and other documents reasonably
requested by Agent, including those specified in the last sentence of SECTION
4.6; and

         (xi) at the time of such Permitted Acquisition and after giving effect
thereto, no Default or Event of Default has occurred and is continuing.

         5.7      DISPOSAL OF ASSETS OR SUBSIDIARY STOCK.
                  ---------------------------------------

transaction or a series of related transactions, any of its property, business
or assets, whether now owned or hereafter acquired, except for (a) sales of

aggregate fair market value of assets sold or otherwise disposed of in any
Fiscal Year does not exceed $3,000,000; (ii) the consideration received is at
least equal to the fair market value of such assets (as determined by the board

continuing or would result from such Asset Disposition.

Loan Document to be untrue or misleading in any material respect. The foregoing
notice requirement shall not be construed to constitute consent by any of the

         6.3      ACCOUNTING TERMS; UTILIZATION OF GAAP FOR PURPOSES OF
         ---      -----------------------------------------------------
                  CALCULATIONS UNDER AGREEMENT.
                  -----------------------------

         For purposes of this Agreement, all accounting terms not otherwise
defined herein shall have the meanings assigned to such terms in conformity with
GAAP. Financial statements and other information furnished to Agent pursuant to
SECTION 6.2 or any other section (unless specifically indicated otherwise) shall
be prepared in accordance with GAAP as in effect at the time of such
preparation; PROVIDED that no Accounting Change shall affect financial
covenants, standards or terms in this Agreement; PROVIDED further that Borrower
shall prepare footnotes to the Financial Statements required to be delivered
hereunder that show the differences between the Financial Statements delivered
(which reflect such Accounting Changes) and the basis for calculating financial
covenant compliance (without reflecting such Accounting Changes). All such
adjustments described in clause (c) of the definition of the term Accounting
Changes resulting from expenditures made subsequent to the Closing Date
(including capitalization of costs and expenses or payment of pre-Closing Date
liabilities) shall be treated as expenses in the period the expenditures are
made. Notwithstanding the foregoing, in the event that any Accounting Change
shall occur and such change results in a change in the method of calculation of
the financial covenants, standards or terms in this Agreement, then Borrower and
Agent agree to negotiate in good faith in order to amend such provisions of this
Agreement so as to equitably reflect such Accounting Changes with the desired
result that the criteria for evaluating the financial condition of the Credit
Parties shall be the same after such Accounting Changes as if such Accounting
Changes had not been made. Until such time as such an amendment shall have been
executed and delivered by Borrower, Agent and the Requisite Lenders, all
financial covenants, standards and terms in this Agreement shall continue to be
calculated or construed as if such Accounting Changes had not occurred.

Commitment shall be reinstated.

         7.3      ACCELERATION AND OTHER REMEDIES.
                  --------------------------------

         Upon the occurrence of any Event of Default described in SECTIONS
7.1(f) or 7.1(g), the Commitments shall be immediately terminated and all of the
Obligations, including the Revolving Loans, shall automatically become
immediately due and payable, without presentment, demand, protest, notice of
intent to accelerate, notice of acceleration or other requirements of any kind,
all of which are hereby expressly waived by Borrower, and the Commitments shall
thereupon terminate. Upon the occurrence and during the continuance of any other
Event of Default, Agent may, and at the request of the Requisite Lenders, Agent
shall, by written notice to Borrower (a) reduce the aggregate amount of the
Commitments from time to time, (b) declare all or any portion of the Loans and

law. Borrower hereby grants to Agent, for the benefit of L/C Issuers and each
Lender with a participation in any Letters of Credit then outstanding, a
security interest in such cash collateral or Acceptable Standby Letter of Credit
to secure all of the Letter of Credit Obligations. Any such cash collateral or
Acceptable Standby Letter of Credit shall be made available by Agent to L/C


                                       56

 Issuers to reimburse L/C Issuers for payments of drafts drawn under such Letters
of Credit and any Fees, Charges and expenses of L/C Issuers with respect to such
Letters of Credit and the unused portion thereof, after all such Letters of
Credit shall have expired or been fully drawn upon, shall be applied to pay any
other Obligations. After all such Letters of Credit shall have expired or been
fully drawn upon and the Termination Date shall have occurred, the balance, if
any, of such cash collateral or Acceptable Standby Letter of Credit shall be

         If any Credit Party shall fail to perform any covenant, duty or
agreement contained in any of the Loan Documents which failure constitutes an
Event of Default, Agent may perform or attempt to perform such covenant, duty or
agreement on behalf of such Credit Party after the expiration of any cure or
grace periods set forth herein. In such event, such Credit Party shall, at the
request of Agent, promptly pay any amount reasonably expended by Agent in such
performance or attempted performance to Agent, together with interest thereon at
the highest rate of interest in effect upon the occurrence of an Event of
Default as specified in SECTION 1.2(d) from the date of such expenditure until
paid. Notwithstanding the foregoing, it is expressly agreed that Agent shall not
have any liability or responsibility for the performance of any obligation of
any Credit Party under this Agreement or any other Loan Document.

         7.5      APPLICATION OF PROCEEDS.
                  ------------------------

         Notwithstanding anything to the contrary contained in this Agreement,
upon the occurrence and during the continuance of an Event of Default, Borrower
irrevocably waives the right to direct the application of any and all payments
at any time or times thereafter received by Agent from or on behalf of Borrower,
and subject to the Intercreditor Agreement, Agent shall have the continuing and
exclusive right to apply and to reapply any and all payments received at any
time or times after the occurrence and during the continuance of an Event of
Default. Notwithstanding anything to the contrary contained in this Agreement
(including, without limitation, SECTION 1.1 and SECTION 1.5 hereof) and subject
to the Intercreditor Agreement, all payments (including the proceeds of any
Asset Disposition or other sale of, or other realization upon, all or any part
of the Collateral) received after acceleration of the Obligations shall be
applied as follows: FIRST, to all costs and expenses incurred by or owing to
Agent and any Lender with respect to this Agreement, the other Loan Documents or
the Collateral; SECOND, to accrued and unpaid interest and Fees with respect to
the Obligations (including any interest which but for the provisions of the
Bankruptcy Code, would have accrued on such amounts); THIRD, to the principal
amount of the Obligations outstanding (including Swap Reimbursement Obligations
but excluding Obligations owed to any Lender under an Interest Rate Agreement)
and to cash collateralize outstanding Letters of Credit (pro rata among all such
Obligations (based upon the principal amount thereof or the outstanding face
amount of such Letters of Credit, as applicable) (and with respect to amounts
applied to Term Loan B, pro rata among all remaining Scheduled Installments
thereof); and FOURTH to any other obligations of Borrower owing to Agent or any
Lender under the Loan Documents or any Interest Rate Agreement. Any balance
remaining shall be delivered to Borrower or to whomever may be lawfully entitled
to receive such balance or as a court of competent jurisdiction may direct.

                          ----------------------------

         8.1      ASSIGNMENTS AND PARTICIPATIONS; BINDING EFFECT.
                  -----------------------------------------------

                  (a) BINDING EFFECT. This Agreement shall become effective when
it shall have been executed by Credit Parties and the Agent and when the Agent
shall have been notified by each Lender and L/C Issuer that such Lender or L/C
Issuer has executed it. Thereafter, it shall be binding upon and inure to the
benefit of, but only to the benefit of, each Credit Party (in each case except
for SECTION 8.2), the Agent, each Lender and L/C Issuer and, to the extent
provided in SECTION 8.2, each other Indemnitee and Secured Party and, in each
case, their respective successors and permitted assigns. Except as expressly
provided in any Loan Document (including in SECTION 8.2), no Credit Party, any
L/C Issuer or the Agent shall have the right to assign any rights or obligations
hereunder or any interest herein.

                  (b) RIGHT TO ASSIGN. Each Lender may sell or assign all or a
portion of its rights and obligations hereunder (including all or a portion of
its Commitments and its rights and obligations with respect to Loans and Letters
of Credit) to (i) any existing Lender, (ii) any Affiliate or Approved Fund of
any existing Lender or (iii) any other Person acceptable (which acceptance shall
not be unreasonably withheld or delayed) to the Agent and, as long as no Event
of Default is continuing, the Borrower; PROVIDED, HOWEVER, that (x) such sales
and assignments do not have to be ratable between the Facilities but must be
ratable among the obligations owing to and owed by such Lender with respect to a
Facility and (y) for each Facility, the aggregate outstanding principal amount
(determined as of the effective date of the applicable Assignment Agreement) of
the Loans, Commitments and Letter of Credit subject to any such sale or
assignment shall be an integral multiple of $1,000,000, unless such sale or
assignment is made to an existing Lender or an Affiliate or Approved Fund of any
existing Lender, is of the assignor's (together with its Affiliates and Approved
Funds) entire interest in such Facility or is made with the prior consent of the
Borrower and the Agent; PROVIDED, FURTHER, HOWEVER that no Lender may sell or
assign all or a portion of its rights hereunder to any Person who is a Credit
Party or who to the actual knowledge of such Lender at the time of the
contemplated assignment is an Affiliate of any Credit Party.

                  (c) PROCEDURE. The parties to each sale or assignment made in
reliance on CLAUSE (B) above (other than those described in CLAUSE (E) or (F)
below) shall execute and deliver to the Agent (which shall keep a copy thereof)
an Assignment Agreement, together with any existing Note subject to such sale or
assignment (or any affidavit of loss therefor acceptable to the Agent and the
Borrower), any tax forms required to be delivered pursuant to SECTION 1.9 and
payment by the assignee of an assignment fee in the amount of $3,500; PROVIDED,
however, that no assignment fee shall be due in connection with an assignment by
a Lender to an existing Lender, an Affiliate of such Lender or an Approved Fund.
Each assigning Lender shall provide notice of each such assignment to Borrower
and Borrower shall update its records to properly reflect such assignment. Upon


                                       58

 receipt of all the foregoing, and conditioned upon such receipt and upon the
Agent consenting to such Assignment Agreement, from and after the effective date
specified in such Assignment Agreement, the Agent shall record or cause to be
recorded in the Loan Account the information contained in such Assignment
Agreement; PROVIDED, however, that that consent of the Agent shall not be
required in connection with an assignment by a Lender to an existing Lender, an
Affiliate of such Lender or an Approved Fund.

                  (d) EFFECTIVENESS. Effective upon the entry of such record in
the Loan Account, (i) such assignee shall become a party hereto and, to the
extent that rights and obligations under the Loan Documents have been assigned
to such assignee pursuant to such Assignment Agreement, shall have the rights
and obligations of a Lender, (ii) any applicable Note shall be transferred to
such assignee through such entry and (iii) the assignor thereunder shall, to the
extent that rights and obligations under this Agreement have been assigned by it
pursuant to such Assignment Agreement, relinquish its rights (except for those
surviving the termination of the Commitments and the payment in full of the
Obligations) and be released from its obligations under the Loan Documents,
other than those relating to events or circumstances occurring prior to such
assignment (and, in the case of an Assignment Agreement covering all or the
remaining portion of an assigning Lender's rights and obligations under the Loan
Documents, such Lender shall cease to be a party hereto except that each Lender
agrees to remain bound by SECTION 8.2, SECTION 8.3 to the extent provided in
SECTION 8.2(n) and SECTION 9.13).

                  (e) GRANT OF SECURITY INTERESTS. In addition to the other
rights provided in this SECTION 8.1, each Lender may grant a security interest
in, or otherwise assign as collateral, any of its rights under this Agreement,
whether now owned or hereafter acquired (including rights to payments of
principal or interest on the Loans), to (A) any federal reserve bank (pursuant
to Regulation A of the Federal Reserve Board) or other funding source in support
of borrowings made by such Lender from such Person, without notice to the Agent
or (B) any holder of, or trustee for the benefit of the holders of, such
Lender's Securities by notice to the Agent; PROVIDED, HOWEVER, that no such
holder or trustee, whether because of such grant or assignment or any
foreclosure thereon (unless such foreclosure is made through an assignment in
accordance with CLAUSE (B) above), shall be entitled to any rights of such
Lender hereunder and no such Lender shall be relieved of any of its obligations
hereunder.

                  (f) PARTICIPANTS AND SPVS. In addition to the other rights
provided in this SECTION 8.1, each Lender may, (x) with notice to the Agent,
grant to an SPV, organized, administered or managed by such Lender, the option
to make all or any part of any Loan that such Lender would otherwise be required
to make hereunder (and the exercise of such option by such SPV and the making of
Loans pursuant thereto shall satisfy the obligation of such Lender to make such
Loans hereunder) and such SPV may assign to such Lender the right to receive
payment with respect to any Obligation and (y) without notice to or consent from
the Agent or the Borrower, sell participations to one or more Persons in or to
all or a portion of its rights and obligations under the Loan Documents
(including all its rights and obligations with respect to the Term Loan,
Revolving Loans and Letters of Credit); PROVIDED, HOWEVER, that, whether as a
result of any term of any Loan Document or of such grant or participation, (i)
no such SPV or participant shall have a commitment, or be deemed to have made an
offer to commit, to make Loans hereunder, and, except as provided in the
applicable option agreement, none shall be liable for any obligation of such
Lender hereunder, (ii) if any such SPV or participant elects not to exercise its


                                       59

 option to fund or otherwise fails to provide all or any part of a Loan, the
Lender granting such option or participation shall be obligated to make such
Loan pursuant to the terms hereof, (iii) such Lender's rights and obligations,
and the rights and obligations of the Credit Parties and the Secured Parties
towards such Lender, under any Loan Document shall remain unchanged and each
other party hereto shall continue to deal solely with such Lender, which shall
remain the holder of the Obligations in the Loan Account, except that (A) each
such participant and SPV shall be entitled to the benefit of SECTIONS 1.8 and
SECTION 1.9, but only to the extent such participant or SPV delivers the tax
forms such Lender is required to collect pursuant to SECTION 1.9 and then only
to the extent of any amount to which such Lender would be entitled in the
absence of any such grant or participation and (B) each such SPV may receive
other payments that would otherwise be made to such Lender pursuant to the terms
hereof with respect to Loans funded by such SPV to the extent provided in the
applicable option agreement and set forth in a notice provided to the Agent by
such SPV and such Lender, PROVIDED, HOWEVER, that in no case (including pursuant
to CLAUSE (A) or (B) above) shall an SPV or participant have the right to
enforce any of the terms of any Loan Document and (iv) the consent of such SPV
or participant shall not be required (either directly, as a restraint on such
Lender's ability to consent hereunder or otherwise) for any amendments, waivers
or consents with respect to any Loan Document or to exercise or refrain from
exercising any powers or rights such Lender may have under or in respect of the
Loan Documents (including the right to enforce or direct enforcement of the
Obligations), except for those described in SECTIONS 9.2(c)(ii) and (c)(iii)
with respect to amounts, or dates fixed for payment of amounts, to which such
participant or SPV would otherwise be entitled and, in the case of participants,
except for releases of all or substantially all of the Collateral (other than in
accordance with this Agreement and the other Loan Documents). No party hereto
shall institute against any SPV grantee of an option pursuant to this clause (f)
any bankruptcy, reorganization, insolvency, liquidation or similar proceeding,
prior to the date that is one year and one day after the payment in full of all
outstanding commercial paper of such SPV; provided, however, that each Lender
having designated an SPV as such agrees to indemnify each Indemnitee against any
Liability that may be incurred by, or asserted against, such Indemnitee as a
result of failing to institute such proceeding (including a failure to get
reimbursed by such SPV for any such Liability). The agreement in the preceding
sentence shall survive the termination of the Commitments and the payment in
full of the Obligations.

                  (g) Nothing contained in this SECTION 8 shall require the
consent of any party for GE Capital to assign any of its rights in respect of
any Swap Related Reimbursement Obligation.

         8.2      AGENT.
                  ------

                  (a) APPOINTMENT. Each Lender hereby designates and appoints GE
Capital as its Agent under this Agreement and the other Loan Documents, and each
Lender hereby irrevocably authorizes Agent to execute and deliver the Collateral
Documents and to take such action or to refrain from taking such action on its
behalf under the provisions of this Agreement and the other Loan Documents and
to exercise such powers as are set forth herein or therein, together with such
other powers as are reasonably incidental thereto. Agent is authorized and
empowered to amend, modify, or waive any provisions of this Agreement or the
other Loan Documents on behalf of Lenders subject to the requirement that
certain of Lenders' consent be obtained in certain instances as provided in this
SECTION 8.2 and SECTION 9.2. The provisions of this SECTION 8.2 are solely for


                                       60

 the benefit of Agent and Lenders and neither Borrower nor any other Credit Party
shall have any rights as a third party beneficiary of any of the provisions
hereof. In performing its functions and duties under this Agreement, Agent shall
act solely as agent of Lenders and does not assume and shall not be deemed to
have assumed any obligation toward or relationship of agency or trust with or
for Borrower or any other Credit Party. Agent may perform any of its duties
hereunder, or under the Loan Documents, by or through its agents or employees.

                  (b) NATURE OF DUTIES. The duties of Agent shall be mechanical
and administrative in nature. Agent shall not have by reason of this Agreement a
fiduciary relationship in respect of any Lender. Nothing in this Agreement or
any of the Loan Documents, express or implied, is intended to or shall be
construed to impose upon Agent any obligations in respect of this Agreement or
any of the Loan Documents except as expressly set forth herein or therein. Each
Lender shall make its own independent investigation of the financial condition
and affairs of each Credit Party in connection with the extension of credit
hereunder and shall make its own appraisal of the creditworthiness of each
Credit Party, and Agent shall have no duty or responsibility, either initially
or on a continuing basis, to provide any Lender with any credit or other
information with respect thereto (other than as expressly required herein). If
Agent seeks the consent or approval of any Lenders to the taking or refraining
from taking any action hereunder, then Agent shall send notice thereof to each
Lender. Agent shall promptly notify each Lender any time that the Requisite
Lenders, Requisite Revolving Lenders or Supermajority Revolving Lenders have
instructed Agent to act or refrain from acting pursuant hereto.

                  (c) RIGHTS, EXCULPATION, ETC. Neither Agent nor any of its
officers, directors, employees or agents shall be liable to any Lender for any
action taken or omitted by them hereunder or under any of the Loan Documents, or
in connection herewith or therewith, except that Agent shall be liable to the
extent of its own gross negligence or willful misconduct as determined by a
final non-appealable order by a court of competent jurisdiction. Agent shall not
be liable for any apportionment or distribution of payments made by it in good
faith and if any such apportionment or distribution is subsequently determined
to have been made in error the sole recourse of any Lender to whom payment was
due but not made, shall be to recover from other Lenders any payment in excess
of the amount to which they are determined to be entitled (and such other
Lenders hereby agree to return to such Lender any such erroneous payments
received by them). In no event shall Agent be liable for punitive, special,
consequential, incidental, exemplary or other similar damages. In performing its
functions and duties hereunder, Agent shall exercise the same care which it
would in dealing with loans for its own account, but neither Agent nor any of
its agents or representatives shall be responsible to any Lender for any
recitals, statements, representations or warranties herein or for the execution,
effectiveness, genuineness, validity, enforceability, collectibility, or
sufficiency of this Agreement or any of the Loan Documents or the transactions
contemplated thereby, or for the financial condition of any Credit Party. Agent
shall not be required to make any inquiry concerning either the performance or
observance of any of the terms, provisions or conditions of this Agreement or
any of the Loan Documents or the financial condition of any Credit Party, or the
existence or possible existence of any Default or Event of Default. Agent may at
any time request instructions from Requisite Lenders, Requisite Revolving


                                       61

 Lenders, Supermajority Revolving Lenders or all affected Lenders with respect to
any actions or approvals which by the terms of this Agreement or of any of the
Loan Documents Agent is permitted or required to take or to grant. If such
instructions are promptly requested, Agent shall be absolutely entitled to
refrain from taking any action or to withhold any approval and shall not be
under any liability whatsoever to any Person for refraining from any action or
withholding any approval under any of the Loan Documents until it shall have
received such instructions from the Requisite Lenders, Requisite Revolving
Lenders, Supermajority Revolving Lenders or such other portion of the Lenders as
shall be prescribed by this Agreement. Without limiting the foregoing, no Lender
shall have any right of action whatsoever against Agent as a result of Agent
acting or refraining from acting under this Agreement or any of the other Loan
Documents in accordance with the instructions of Requisite Lenders, Requisite
Revolving Lenders, Supermajority Revolving Lenders or all affected Lenders, as
applicable; and, notwithstanding the instructions of Requisite Lenders,
Requisite Revolving Lenders, Supermajority Revolving Lenders or all affected
Lenders, as applicable, Agent shall have no obligation to take any action if it
believes, in good faith, that such action is deemed to be illegal by Agent or
exposes Agent to any liability for which it has not received satisfactory
indemnification in accordance with SECTION 8.2(e).

                  (d) RELIANCE. Agent shall be entitled to rely, and shall be
fully protected in relying, upon any written or oral notices, statements,
certificates, orders or other documents or any telephone message or other
communication (including any writing, telex, fax or telegram) believed by it in
good faith to be genuine and correct and to have been signed, sent or made by
the proper Person, and with respect to all matters pertaining to this Agreement
or any of the Loan Documents and its duties hereunder or thereunder. Agent shall
be entitled to rely upon the advice of legal counsel, independent accountants,
and other experts selected by Agent in its sole discretion.

                  (e) INDEMNIFICATION. Lenders will reimburse and indemnify
Agent for and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses (including, without
limitation, attorneys' fees and expenses), advances or disbursements of any kind
or nature whatsoever which may be imposed on, incurred by, or asserted against
Agent in its capacity as such in any way relating to or arising out of this
Agreement or any of the Loan Documents or any action taken or omitted by Agent
in its capacity as such in under this Agreement or any of the Loan Documents, in
proportion to each Lender's Pro Rata Share, but only to the extent that any of
the foregoing is not reimbursed by Borrower; provided, however, that no Lender
shall be liable for any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses, advances or
disbursements to the extent resulting from Agent's gross negligence or willful
misconduct as determined by a final non-appealable order by a court of competent
jurisdiction. If any indemnity furnished to Agent for any purpose shall, in the
opinion of Agent, be insufficient or become impaired, Agent may call for
additional indemnity and cease, or not commence, to do the acts indemnified
against even if so directed by the Requisite Lenders, Requisite Revolving
Lenders, Supermajority Revolving Lenders or such other portion of the Lenders as
shall be prescribed by this Agreement until such additional indemnity is
furnished. The obligations of Lenders under this SECTION 8.2(E) shall survive
the payment in full of the Obligations and the termination of this Agreement.

                  (f) GE CAPITAL (OR ANY SUCCESSOR AGENT) INDIVIDUALLY. With
respect to its Commitments hereunder, GE Capital (or any successor Agent) shall
have and may exercise the same rights and powers hereunder and is subject to the
same obligations and liabilities as and to the extent set forth herein for any
other Lender. The terms "Lenders," "Requisite Lenders," "Requisite Revolving
Lenders," "Supermajority Revolving Lenders" or any similar terms shall, unless
the context clearly otherwise indicates, include GE Capital (or any successor


                                       62

 Agent) in its individual capacity as a Lender or one of the Requisite Lenders,
Requisite Revolving Lenders or Supermajority Revolving Lenders. GE Capital (or
any successor Agent), either directly or through strategic affiliations, may
lend money to, acquire equity or other ownership interests in, provide advisory
services to and generally engage in any kind of banking, trust or other business
with any Credit Party as if it were not acting as Agent pursuant hereto and
without any duty to account therefor to Lenders. GE Capital (or any successor
Agent), either directly or through strategic affiliations, may accept fees and
other consideration from any Credit Party for services in connection with this
Agreement or otherwise without having to account for the same to Lenders.

                  (g) SUCCESSOR AGENT.

                           (i) RESIGNATION. Upon notice to the Borrower, Agent
may, and upon written request of Requisite Lenders shall, resign from the
performance of all its agency functions and duties hereunder at any time. Such
resignation shall take effect immediately unless otherwise indicated by the
Requisite Lenders or Agent, as the case may be, provided it is understood and
agreed that the removed or resigning Agent ("PRIOR AGENT") may be required to
remain in its role as collateral agent for a reasonable period of time with
respect to holding and perfecting Liens on Collateral to allow documentation of
the transfer of the agency responsibility and authority. It is understood that
the Prior Agent shall retain all of the benefits of the indemnity provisions
contained in this Agreement during such period.

                           (ii) APPOINTMENT OF SUCCESSOR. Upon any such notice
of resignation pursuant to clause (i) above, Requisite Lenders shall appoint a
successor Agent which, unless an Event of Default has occurred and is
continuing, shall be subject to Borrower's approval (which shall not be
unreasonably withheld or delayed). If a successor Agent shall not have been so
appointed within the thirty (30) Business Day period referred to in clause (i)
above, the retiring Agent, upon notice to Borrower, shall then appoint a
successor Agent who shall serve as Agent until such time, if any, as Requisite
Lenders appoint a successor Agent as provided above.

                           (iii) SUCCESSOR AGENT. Upon the acceptance of any
appointment as Agent under the Loan Documents by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations under the Loan
Documents. After any retiring Agent's resignation as Agent, the provisions of
this SECTION 8.2 shall continue to inure to its benefit as to any actions taken
or omitted to be taken by it in its capacity as Agent.

                  (h)      COLLATERAL MATTERS.
                           -------------------

                           (i) RELEASE OF COLLATERAL. Lenders hereby irrevocably
authorize Agent, at its option and in its discretion, to release or subordinate
any Lien granted to or held by Agent upon any Collateral (w) with respect to any
assets that are subject to a Permitted Encumbrance described in clause (j) or
(l) of the definition of Permitted Encumbrances so long as such release or
subordination is made in connection with the acquisition of such asset, (x) on


                                       63

 the Termination Date, (y) constituting property being sold or disposed of if
Borrower certifies to Agent that the sale or disposition is made in compliance
with the provisions of this Agreement (and Agent may rely in good faith
conclusively on any such certificate, without further inquiry) or (z) in
accordance with the provisions of the next sentence.

                           (ii) CONFIRMATION OF AUTHORITY; EXECUTION OF
RELEASES. Without in any manner limiting Agent's authority to act without any
specific or further authorization or consent by Lenders (as set forth in SECTION
8.2(h)(i)), each Lender agrees to confirm in writing, upon request by Agent or
Borrower, the authority to release any Collateral conferred upon Agent under
clauses (x) and (y) of SECTION 8.2(h)(i). Upon receipt by Agent of any required
confirmation from the Requisite Lenders of its authority to release any
particular item or types of Collateral, and upon at least ten (10) Business
Days' prior written request by Borrower, Agent shall (and is hereby irrevocably
authorized by Lenders to) execute such documents as may be necessary to evidence
the release of the Liens granted to Agent upon such Collateral; PROVIDED,
HOWEVER, that (x) Agent shall not be required to execute any such document on
terms which, in Agent's opinion, would expose Agent to liability or create any
obligation or entail any consequence other than the release of such Liens
without recourse or warranty, and (y) such release shall not in any manner
discharge, affect or impair the Obligations or any Liens upon (or obligations of
any Credit Party, in respect of), all interests retained by any Credit Party,
including the proceeds of any sale, all of which shall continue to constitute
part of the Collateral.

                           (iii) ABSENCE OF DUTY. Agent shall have no obligation
whatsoever to any Lender or any other Person to assure that the property covered
by the Collateral Documents exists or is owned by Borrower or any other Credit
Party or is cared for, protected or insured or has been encumbered or that the
Liens granted to Agent have been properly or sufficiently or lawfully created,
perfected, protected or enforced or are entitled to any particular priority, or
to exercise at all or in any particular manner or under any duty of care,
disclosure or fidelity, or to continue exercising, any of the rights,
authorities and powers granted or available to Agent in this SECTION 8.2(h) or
in any of the Loan Documents, it being understood and agreed that in respect of
the property covered by the Collateral Documents or any act, omission or event
related thereto, Agent may act in any manner it may deem appropriate, in its
discretion, given Agent's own interest in property covered by the Collateral
Documents as one of the Lenders and that Agent shall have no duty or liability
whatsoever to any of the other Lenders, PROVIDED that Agent shall exercise the
same care which it would in dealing with loans for its own account.

                  (i) AGENCY FOR PERFECTION. Agent and each Lender hereby
appoint each other Lender as agent for the purpose of perfecting Agent's
security interest in assets which, in accordance with the Code in any applicable
jurisdiction, can be perfected by possession or control. Should any Lender
(other than Agent) obtain possession or control of any such assets, such Lender
shall notify Agent thereof, and, promptly upon Agent's request therefor, shall
deliver such assets to Agent or in accordance with Agent's instructions or
transfer control to Agent in accordance with Agent's instructions. Each Lender
agrees that it will not have any right individually to enforce or seek to
enforce any Collateral Document or to realize upon any collateral security for
the Loans unless instructed to do so by Agent in writing, it being understood
and agreed that such rights and remedies may be exercised only by Agent.

                                       64

                  (j) NOTICE OF DEFAULT. Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default except
with respect to defaults in the payment of principal, interest and Fees required
to be paid to Agent for the account of Lenders, unless Agent shall have received
written notice from a Lender or Borrower referring to this Agreement, describing
such Default or Event of Default and stating that such notice is a "notice of
default". Agent will use reasonable efforts to promptly notify each Lender of
its receipt of any such notice, unless such notice is with respect to defaults
in the payment of principal, interest and fees, in which case Agent will notify
each Lender of its receipt of such notice. Agent shall take such action with
respect to such Default or Event of Default as may be requested by Requisite
Lenders in accordance with SECTION 7. Unless and until Agent has received any
such request, Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable or in the best interests of Lenders.

                  (k) LENDER ACTIONS AGAINST COLLATERAL. Each Lender agrees that
it will not take any enforcement action, nor institute any actions or
proceedings, with respect to the Loans, against Borrower or any Credit Party
hereunder or under the other Loan Documents or against any Collateral (including
the exercise of any right of set-off) without the consent of the Agent or
Requisite Lenders. All such enforcement actions and proceedings shall be (i)
taken in concert and (ii) at the direction of or with the consent of Agent or
Requisite Lenders. Agent is authorized to issue all notices to be issued by or
on behalf of Lenders with respect to any Subordinated Debt and the Second Lien
Loan. With respect to any action by Agent to enforce the rights and remedies of
Agent and the Lenders under this Agreement and the other Loan Documents, each
Lender hereby consents to the jurisdiction of the court in which such action is
maintained, and agrees to deliver its Notes to Agent to the extent necessary to
enforce the rights and remedies of Agent for the benefit of the Lenders under
any mortgages in accordance with the provisions hereof.

                  (l) AGENT REPORTS. Each Lender may from time to time receive
one or more reports or other information (each, a "REPORT") prepared by or on
behalf of Agent (or one or more of Agent's Affiliates). With respect to each
Report, each Lender hereby agrees that:

                           (i) Agent (and Agent's Affiliates) shall have no
duties or obligations in connection with or as a result of a Lender receiving a
copy of a Report, which will be provided solely as a courtesy, without
consideration. Each Lender will perform its own diligence and will make its own
independent investigation of the operations, financial conditions and affairs of
the Credit Parties and will not rely on any Report or make any claim that it has
done so. In addition, each Lender releases, and agrees that it will not assert,
any claim against Agent (or one or more of Agent's Affiliates) that in any way
relates to any Report or arises out of a Lender having access to any Report or
any discussion of its contents, and each Lender agrees to indemnify and hold
harmless Agent (and Agent's Affiliates) and their respective officers,
directors, employees, agents and attorneys from all claims, liabilities and
expenses relating to a breach by a Lender or any of its personnel of this
Section or otherwise arising out of a Lender's access to any Report or any
discussion of its contents;

                                       65

                           (ii) Each Report may not be complete and certain
information and findings obtained by Agent (or one or more of Agent's
Affiliates) regarding the operations and condition of the Credit Parties may not
be reflected in each Report. Agent (and Agent's Affiliates) makes no
representations or warranties of any kind with respect to (i) any existing or
proposed financing; (ii) the accuracy or completeness of the information
contained in any Report or in any other related documentation; (iii) the scope
or adequacy of Agent's (and Agent's Affiliates') due diligence, or the presence
or absence of any errors or omissions contained in any Report or in any other
related documentation; and (iv) any work performed by Agent (or one or more of
Agent's Affiliates) in connection with or using any Report or any related
documentation; and

                           (iii) Each Lender agrees to safeguard each Report and
any related documentation with the same care which it uses with respect to
information of its own which it does not desire to disseminate or publish, and
agrees not to reproduce or distribute or provide copies of or disclose any
Report or any other related documentation or any related discussions to anyone.

                  (m) INTERCREDITOR AGREEMENT AND POST-CLOSING AGREEMENT. EACH
LENDER AND EACH OTHER PERSON PARTY HERETO FROM TIME TO TIME (OTHER THAN THE
CREDIT PARTIES) HEREBY (A) ACKNOWLEDGES THAT IT HAS RECEIVED A COPY OF THE
INTERCREDITOR AGREEMENT, (B) CONSENTS TO THE PROVISIONS OF THE INTERCREDITOR
AGREEMENT, (C) AGREES THAT IT WILL BE BOUND BY AND WILL TAKE NO ACTIONS CONTRARY
TO THE PROVISIONS OF THE INTERCREDITOR AGREEMENT AND (D) AUTHORIZES AND
INSTRUCTS THE AGENT ON ITS BEHALF TO ENTER INTO THE INTERCREDITOR AGREEMENT AS
FIRST LIEN AGENT (AS DEFINED THEREIN) AND ON BEHALF OF SUCH LENDER. AGENT IS
AUTHORIZED TO EXECUTE AND DELIVER THE POST-CLOSING AGREEMENT, AND EACH LENDER BY
MAKING OR PURCHASING AN INTEREST IN ANY LOAN AT ANY TIME SHALL BE DEEMED TO HAVE
AGREED TO BE BOUND BY SUCH AGREEMENT.

                  (n) ADDITIONAL SECURED PARTIES. The benefit of the provisions
of the Loan Documents directly relating to the Collateral or any Lien granted
thereunder shall extend to and be available to any Secured Party that is not a
Lender as long as, by accepting such benefits, such Secured Party agrees, as
among the Agent and all other Secured Parties, that such Secured Party is bound
by (and, if requested by the Agent, shall confirm such agreement in a writing in
form and substance acceptable to the Agent) this SECTION 8.2, SECTION 8.3 and
SECTION 9.13 and the decisions and actions of the Agent and the Required Lenders
(or, where expressly required by the terms of this Agreement, a greater
proportion of the Lenders) to the same extent a Lender is bound; PROVIDED,
HOWEVER, that, notwithstanding the foregoing, (a) such Secured Party shall be
bound by SECTION 8.2(e) only to the extent of Liabilities, costs and expenses
with respect to or otherwise relating to the Collateral held for the benefit of
such Secured Party, in which case the obligations of such Secured Party
thereunder shall not be limited by any concept of Pro Rata Share or similar
concept, (b) each of the Agent and the Lenders shall be entitled to act at its
sole discretion, without regard to the interest of such Secured Party,
regardless of whether any Obligation to such Secured Party thereafter remains
outstanding, is deprived of the benefit of the Collateral, becomes unsecured or


                                       66

 is otherwise affected or put in jeopardy thereby, and without any duty or
liability to such Secured Party or any such Obligation and (c) such Secured
Party shall not have any right to be notified of, consent to, direct, require or
be heard with respect to, any action taken or omitted in respect of the
Collateral or under any Loan Document.

         8.3      SET OFF AND SHARING OF PAYMENTS.
                  --------------------------------

         Subject to SECTION 8.2(k), in addition to any rights now or hereafter
granted under applicable law and not by way of limitation of any such rights,
during the continuance of any Event of Default, each Lender is hereby authorized
by Borrower at any time or from time to time, with reasonably prompt subsequent
notice to Borrower (any prior or contemporaneous notice being hereby expressly
waived) to set off and to appropriate and to apply any and all (A) balances held
by such Lender at any of its offices for the account of Borrower or any of its
Subsidiaries (regardless of whether such balances are then due to Borrower or
its Subsidiaries), and (B) other property at any time held or owing by such
Lender to or for the credit or for the account of Borrower or any of its
Subsidiaries, against and on account of any of the Obligations; except that no
Lender shall exercise any such right without the prior written consent of Agent.
Notwithstanding anything herein to the contrary, the failure to give notice of
any set off and application made by such Lender to Borrower shall not affect the
validity of such set off and application. Any Lender exercising a right to set
off shall purchase for cash (and the other Lenders shall sell) interests in each
of such other Lender's Pro Rata Share of the Obligations as would be necessary
to cause all Lenders to share the amount so set off with each other Lender
entitled to share in the amount so set off in accordance with their respective
Pro Rata Shares. Borrower agrees, to the fullest extent permitted by law, that
any Lender may exercise its right to set off with respect to amounts in excess
of its Pro Rata Share of the Obligations and upon doing so shall deliver such
amount so set off to the Agent for the benefit of all Lenders entitled to share
in the amount so set off in accordance with their Pro Rata Shares.

         8.4      DISBURSEMENT OF FUNDS.
                  ----------------------

         Agent may, on behalf of Lenders, disburse funds to Borrower for Loans
requested. Each Lender shall reimburse Agent on demand for all funds disbursed
on its behalf by Agent, or if Agent so requests, each Lender will remit to Agent
its Pro Rata Share of any Loan before Agent disburses same to Borrower. If Agent
elects to require that each Lender make funds available to Agent prior to a
disbursement by Agent to Borrower, Agent shall advise each Lender by telephone
or fax of the amount of such Lender's Pro Rata Share of the Loan requested by
Borrower no later than 1:00 p.m. (New York time) on the Funding Date applicable
thereto, and each such Lender shall pay Agent such Lender's Pro Rata Share of
such requested Loan, in same day funds, by wire transfer to Agent's account on
such Funding Date. If any Lender fails to pay the amount of its Pro Rata Share
within one (1) Business Day after Agent's demand, Agent shall promptly notify
Borrower, and Borrower shall immediately repay such amount to Agent. Any
repayment required pursuant to this SECTION 8.4 shall be without premium or
penalty. Nothing in this SECTION 8.4 or elsewhere in this Agreement or the other
Loan Documents, including the provisions of SECTION 8.5, shall be deemed to
require Agent to advance funds on behalf of any Lender or to relieve any Lender
from its obligation to fulfill its commitments hereunder or to prejudice any
rights that Agent or Borrower may have against any Lender as a result of any
default by such Lender hereunder.

                                       67

         8.5      DISBURSEMENTS OF ADVANCES; PAYMENT.
                  -----------------------------------

                  (a) ADVANCES; PAYMENTS.

                           (i) Revolving Lenders shall refund or participate in
the Swing Line Loan in accordance with clauses (iii) and (iv) of SECTION 1.1(C).
If the Swing Line Lender declines to make a Swing Line Advance or if Swing Line
Availability is zero, Agent shall notify Revolving Lenders, promptly after
receipt of a Notice of Revolving Credit Advance and in any event prior to 1:00
p.m. (New York time) on the date such Notice of a Revolving Credit Advance is
received, by fax, telephone or other similar form of transmission. Each
Revolving Lender shall make the amount of such Lender's Pro Rata Share of such
Revolving Credit Advance available to Agent in same day funds by wire transfer
to Agent's account as set forth in SECTION 1.1(e) not later than 3:00 p.m. (New
York time) on the requested Funding Date in the case of an Index Rate Loans and
not later than 11:00 a.m. (New York time) on the requested Funding Date in the
case of a LIBOR Loan. After receipt of such wire transfers (or, in the Agent's
sole discretion, before receipt of such wire transfers), subject to the terms
hereof, Agent shall make the requested Revolving Credit Advance to Borrower as
designated by Borrower in the Notice of Revolving Credit Advance. All payments
by each Revolving Lender shall be made without setoff, counterclaim or deduction
of any kind.

                           (ii) At least once each calendar week or more
frequently at Agent's election (each, a "SETTLEMENT DATE"), Agent shall advise
each Lender by telephone or fax of the amount of such Lender's Pro Rata Share of
principal, interest and Fees paid for the benefit of Lenders with respect to
each applicable Loan. Provided that each Lender has funded all payments and
Advances required to be made by it and funded all purchases of participations
required to be funded by it under this Agreement and the other Loan Documents as
of such Settlement Date, Agent shall pay to each Lender such Lender's Pro Rata
Share of principal, interest and Fees paid by Borrower since the previous
Settlement Date for the benefit of such Lender on the Loans held by it. Such
payments shall be made by wire transfer to such Lender's account (as specified
by such Lender in ANNEX E or the applicable Assignment Agreement) not later than
2:00 p.m. (New York time) on the next Business Day following each Settlement
Date. To the extent that any Lender (a "NON-FUNDING LENDER") has failed to fund
all such payments and Advances or failed to fund the purchase of all such
participations required to be funded by such Lender pursuant to this Agreement,
Agent shall be entitled to set off the funding shortfall against that
Non-Funding Lender's Pro Rata Share of all payments received from Borrower.

                  (b) AVAILABILITY OF LENDER'S PRO RATA SHARE. Agent may assume
that each Revolving Lender will make its Pro Rata Share of each Revolving Credit
Advance available to Agent on each Funding Date. If such Pro Rata Share is not,
in fact, paid to Agent by such Revolving Lender when due, Agent will be entitled
to recover such amount on demand from such Revolving Lender without setoff,
counterclaim or deduction of any kind. If any Revolving Lender fails to pay the
amount of its Pro Rata Share forthwith upon Agent's demand, Agent shall promptly
notify Borrower and Borrower shall immediately repay such amount to Agent.
Nothing in this SECTION 8.5(b) or elsewhere in this Agreement or the other Loan
Documents shall be deemed to require Agent to advance funds on behalf of any


                                       68

 Revolving Lender or to relieve any Revolving Lender from its obligation to
fulfill its Commitments hereunder or to prejudice any rights that Borrower may
have against any Revolving Lender as a result of any default by such Revolving
Lender hereunder. To the extent that Agent advances funds to Borrower on behalf
of any Revolving Lender and is not reimbursed therefor on the same Business Day
as such Advance is made, Agent shall be entitled to retain for its account all
interest accrued on such Advance until reimbursed by the applicable Revolving
Lender.

                  (c) RETURN OF PAYMENTS.

                           (i) If Agent pays an amount to a Lender under this
Agreement in the belief or expectation that a related payment has been or will
be received by Agent from Borrower and such related payment is not received by
Agent, then Agent will be entitled to recover such amount from such Lender on
demand without setoff, counterclaim or deduction of any kind.

                           (ii) If Agent determines at any time that any amount
received by Agent under this Agreement must be returned to Credit Party or paid
to any other Person pursuant to any insolvency law or otherwise, then,
notwithstanding any other term or condition of this Agreement or any other Loan
Document, Agent will not be required to distribute any portion thereof to any
Lender. In addition, each Lender will repay to Agent on demand any portion of
such amount that Agent has distributed to such Lender, together with interest at
such rate, if any, as Agent is required to pay to Borrower or such other Person,
without setoff, counterclaim or deduction of any kind.

                  (d) NON-FUNDING LENDERS. The failure of any Non-Funding Lender
to make any Revolving Credit Advance or any payment required by it hereunder, or
to fund any purchase of any participation in any Swing Line Loan to be made or
funded by it on the date specified therefor shall not relieve any other Lender
(each such other Revolving Lender, an "OTHER LENDER") of its obligations to make
such Advance or fund the purchase of any such participation on such date, but
neither any Other Lender nor Agent shall be responsible for the failure of any
Non-Funding Lender to make an Advance, fund the purchase of a participation or
make any other payment required hereunder. Notwithstanding anything set forth
herein to the contrary, a Non-Funding Lender shall not have any voting or
consent rights under or with respect to any Loan Document or constitute a
"Lender" or a "Revolving Lender" (or be included in the calculation of
"Requisite Lenders", "Requisite Revolving Lenders" or "Supermajority Revolving
Lenders" hereunder) for any voting or consent rights under or with respect to
any Loan Document.

                                   SECTION 9.
                                  MISCELLANEOUS
                                  -------------

         9.1      INDEMNITIES.
                  ------------

         Borrower agrees to indemnify, pay, and hold Agent, each Lender, each
L/C Issuer and their respective Affiliates, officers, directors, employees,
agents, and attorneys (the "INDEMNITEES") harmless from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims, costs and expenses (including all reasonable fees and expenses of
counsel to such Indemnitees) of any kind or nature whatsoever that may be
imposed on, incurred by, or asserted against the Indemnitee as a result of such


                                       69

 Indemnitees being a party to this Agreement or the transactions consummated
pursuant to this Agreement or otherwise relating to any of the Loan Documents or
Related Transactions; provided, that Borrower shall have no obligation to an
Indemnitee hereunder with respect to liabilities to the extent resulting from
the gross negligence or willful misconduct of that Indemnitee as determined by a
court of competent jurisdiction. If and to the extent that the foregoing
undertaking may be unenforceable for any reason, Borrower agrees to make the
maximum contribution to the payment and satisfaction thereof which is
permissible under applicable law.

signed by Agent, Requisite Revolving Lenders and Borrower. Notwithstanding
anything contained in this Agreement to the contrary, no waiver or consent with
respect to any Default or any Event of Default shall be effective for purposes

Related Reimbursement Obligations, under this Agreement or any other Loan
Document, including any release of any Guaranty or Collateral requiring a
writing signed by all Lenders, shall be effective unless in writing and signed
by Agent or L/C Issuer or GE Capital, as the case may be, in addition to Lenders
required hereinabove to take such action. Each amendment, modification,
termination or waiver shall be effective only in the specific instance and for
the specific purpose for which it was given. No amendment, modification,
termination or waiver shall be required for Agent to take additional Collateral
pursuant to any Loan Document. No amendment, modification, termination or waiver
of any provision of any Note shall be effective without the written concurrence
of the holder of that Note. No notice to or demand on any Credit Party in any
case shall entitle such Credit Party or any other Credit Party to any other or
further notice or demand in similar or other circumstances. Any amendment,
modification, termination, waiver or consent effected in accordance with this
SECTION 9.2 shall be binding upon each holder of the Notes at the time
outstanding and each future holder of the Notes.

SUBSECTION (A), each of the Agent, the Borrower, the Lenders, the L/C Issuers
and each of their authorized representatives is authorized (but not required) to
transmit, post or otherwise make or communicate, in its sole discretion,
Electronic Transmissions in connection with any Loan Document and the
transactions contemplated therein. Each of Holdings, the Borrower and each
Credit Party hereby acknowledges and agrees, and each of Holdings and the
Borrower shall cause each other Credit Party to acknowledge and agree, that the
use of Electronic Transmissions is not necessarily secure and that there are
risks associated with such use, including risks of interception, disclosure and
abuse and each indicates it assumes and accepts such risks by hereby authorizing
the transmission of Electronic Transmissions.

E-Signature, upon which each Credit Party may rely and assume the authenticity
thereof, (iii) each such posting containing a signature, a reproduction of a
signature or an E-Signature shall, for all intents and purposes, have the same
effect and weight as a signed paper original and (iv) each party hereto or
beneficiary hereto agrees not to contest the validity or enforceability of any
posting on any E-System or E-Signature on any such posting under the provisions

shall be governed by and subject to, in addition to SUBSECTIONS (a) and (b) and
this SUBSECTION (c), separate terms and conditions posted or referenced in such
E-System and related Contractual Obligations executed by Credit Parties in
connection with the use of such E-System.

                           (iv) LIMITATION OF LIABILITY. ALL E-SYSTEMS AND

AGENT OR ANY OF ITS RELATED PERSONS WARRANTS THE ACCURACY, ADEQUACY OR
COMPLETENESS OF ANY E-SYSTEMS OR ELECTRONIC TRANSMISSION, AND EACH DISCLAIMS ALL

THE AGENT OR ANY OF ITS RELATED PERSONS IN CONNECTION WITH ANY E SYSTEMS OR
ELECTRONIC COMMUNICATION, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR
A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD-PARTY RIGHTS OR FREEDOM FROM
VIRUSES OR OTHER CODE DEFECTS. Each of Holdings, the Borrower and each Credit


                                       73

 Party agrees (and each of Holdings and the Borrower shall cause each other
Credit Party to agree) that the Agent has no responsibility for maintaining or
providing any equipment, software, services or any testing required in
connection with any Electronic Transmission or otherwise required for any
E-System.

         9.4      FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.
                  ------------------------------------------------------

         No failure or delay on the part of Agent or any Lender to exercise, nor
any partial exercise of, any power, right or privilege hereunder or under any
other Loan Documents shall impair such power, right, or privilege or be
construed to be a waiver of any Default or Event of Default. All rights and
remedies existing hereunder or under any other Loan Document are cumulative to
and not exclusive of any rights or remedies otherwise available.

         9.5      MARSHALING; PAYMENTS SET ASIDE.
                  -------------------------------

         Neither Agent nor any Lender shall be under any obligation to marshal
any assets in payment of any or all of the Obligations. To the extent that
Borrower makes payment(s) or Agent enforces its Liens or Agent or any Lender
exercises its right of set-off, and such payment(s) or the proceeds of such
enforcement or set-off is subsequently invalidated, declared to be fraudulent or
preferential, set aside, or required to be repaid by anyone (whether as a result
of any demand, litigation, settlement or otherwise), then to the extent of such
recovery, the Obligations or part thereof originally intended to be satisfied,
and all Liens, rights and remedies therefor, shall be revived and continued in
full force and effect as if such payment had not been made or such enforcement
or set-off had not occurred.

         9.6      SEVERABILITY.
                  -------------

         The invalidity, illegality, or unenforceability in any jurisdiction of
any provision under the Loan Documents shall not affect or impair the remaining
provisions in the Loan Documents.

         9.7      LENDERS' OBLIGATIONS SEVERAL; INDEPENDENT NATURE OF LENDERS'
                  ------------------------------------------------------------
                  RIGHTS.
                  -------

         The obligation of each Lender hereunder is several and not joint and no
Lender shall be responsible for the obligation or commitment of any other Lender
hereunder. In the event that any Lender at any time should fail to make a Loan
as herein provided, the Lenders, or any of them, at their sole option, may make
the Loan that was to have been made by the Lender so failing to make such Loan.
Nothing contained in any Loan Document and no action taken by Agent or any
Lender pursuant hereto or thereto shall be deemed to constitute Lenders to be a
partnership, an association, a joint venture or any other kind of entity. The
amounts payable at any time hereunder to each Lender shall be a separate and
independent debt.

         9.8      HEADINGS.
                  ---------

         Section and subsection headings are included herein for convenience of
reference only and shall not constitute a part of this Agreement for any other
purposes or be given substantive effect.

                                       74

         9.9      APPLICABLE LAW.
                  ---------------

         THIS AGREEMENT AND EACH OF THE OTHER LOAN DOCUMENTS WHICH DOES NOT
EXPRESSLY SET FORTH APPLICABLE LAW SHALL BE GOVERNED BY AND SHALL BE CONSTRUED
AND ENFORCED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK.

         9.10     SUCCESSORS AND ASSIGNS.
                  -----------------------

         This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns except that
Borrower may not assign its rights or obligations hereunder without the written
consent of all Lenders and any such purported assignment without such written
consent shall be void.

         9.11     NO FIDUCIARY RELATIONSHIP; LIMITED LIABILITY.
                  ---------------------------------------------

         No provision in the Loan Documents and no course of dealing between the
parties shall be deemed to create any fiduciary duty owing to any Credit Party
by Agent or any Lender. Borrower and each other Credit Party agree that neither
Agent nor any Lender shall have liability to Borrower or any other Credit Party
(whether sounding in tort, contract or otherwise) for losses suffered by
Borrower or any other Credit Party in connection with, arising out of, or in any
way related to the transactions contemplated and the relationship established by
the Loan Documents, or any act, omission or event occurring in connection
therewith, unless and to the extent that it is determined that such losses
resulted from the gross negligence or willful misconduct of the party from which
recovery is sought as determined by a final non-appealable order by a court of
competent jurisdiction. Neither Agent nor any Lender shall have any liability
with respect to, and Borrower and each other Credit Party hereby waive, release
and agree not to sue for, any special, indirect or consequential damages
suffered by Borrower and any other Credit Party in connection with, arising out
of, or in any way related to the Loan Documents or the transactions contemplated
thereby.

         9.12     CONSTRUCTION.
                  -------------

         Agent, each Lender, Borrower and each other Credit Party acknowledge
that each of them has had the benefit of legal counsel of its own choice and has
been afforded an opportunity to review the Loan Documents with its legal counsel
and that the Loan Documents shall be construed as if jointly drafted by Agent,
each Lender, Borrower and each other Credit Party.

         9.13     CONFIDENTIALITY.
                  ----------------

         Until the Termination Date, Agent and each Lender agree to exercise
their best efforts to keep confidential any non-public information delivered
pursuant to the Loan Documents and identified as such by Borrower and not to
disclose such information to Persons other than to potential assignees or
participants or to any Affiliate of, or Persons employed by or engaged, by
Agent, a Lender or any of their respective Affiliates or a Lender's assignees or
participants including attorneys, auditors, professional consultants, rating
agencies, insurance industry associations and portfolio management services, or
to a Person that is an investor or prospective investor in a Securitization,


                                       75

 that agrees that its access to information regarding the Borrower and the Loans
is solely for purposes of evaluating an investment in such Securitization, or to
a Person that is a trustee, collateral manager, servicer, noteholder or secured
party in a Securitization in connection with the administration, servicing and
reporting on the assets serving as collateral for such Securitization. The
confidentiality provisions contained in this SECTION 9.13 shall not apply to
disclosures (a) required to be made by Agent or any Lender to any regulatory or
governmental agency or pursuant to (i) any subpoena or similar legal process or

         9.17     ENTIRE AGREEMENT.
                  -----------------

         This Agreement, the Notes and the other Loan Documents embody the
entire agreement among the parties hereto and supersede all prior commitments,
agreements, representations, and understandings, whether oral or written,
relating to the subject matter hereof (other than the GE Capital Fee Letter),
and may not be contradicted or varied by evidence of prior, contemporaneous, or

         9.18     COUNTERPARTS; EFFECTIVENESS.

         This Agreement and any amendments, waivers, consents or supplements may

deemed an original, but all of which counterparts together shall constitute but

execution of a counterpart hereof by each of the parties hereto.

         9.19     REPLACEMENT OF LENDERS.
         ----     -----------------------

                  (a) Within fifteen (15) days after receipt by Borrower of
written notice and demand from any Lender for payment pursuant to SECTION 1.8 or
1.9 or, as provided in SECTION 9.19(c), in the case of certain refusals by any
Lender to consent to certain proposed amendments, modifications, terminations or
waivers with respect to this Agreement that have been approved by Requisite
Lenders, Requisite Revolving Lenders, Supermajority Revolving Lenders or all
affected Lenders, as applicable (any such Lender demanding such payment or
refusing to so consent being referred to herein as an "AFFECTED LENDER"),
Borrower may, at its option, notify Agent and such Affected Lender of its
intention to do one of the following:

                                       77

                           (i) Borrower may obtain, at Borrower's expense, a
replacement Lender ("REPLACEMENT LENDER") for such Affected Lender, which
Replacement Lender shall be reasonably satisfactory to Agent. In the event
Borrower obtains a Replacement Lender that will purchase all outstanding
Obligations owed to such Affected Lender and assume its Commitments hereunder
within ninety (90) days following notice of Borrower's intention to do so, the
Affected Lender shall sell and assign all of its rights and delegate all of its
obligations under this Agreement to such Replacement Lender in accordance with
the provisions of SECTION 8.1, PROVIDED that Borrower has reimbursed such
Affected Lender for any administrative fee payable pursuant to SECTION 8.1 and,
in any case where such replacement occurs as the result of a demand for payment
pursuant to SECTION 1.8 or 1.9, paid all amounts required to be paid to such
Affected Lender pursuant to SECTION 1.8 or 1.9 through the date of such sale and
assignment; or

                           (ii) Borrower may, with Agent's consent, prepay in
full all outstanding Obligations owed to such Affected Lender and terminate such
Affected Lender's Pro Rata Share of the Revolving Loan Commitment and Pro Rata
Share of the Term Loan B Commitment, in which case the Revolving Loan Commitment
and Term Loan B Commitment will be reduced by the amount of such Pro Rata Share.
Borrower shall, within ninety (90) days following notice of its intention to do
so, prepay in full all outstanding Obligations owed to such Affected Lender
(including, in any case where such prepayment occurs as the result of a demand
for payment for increased costs, such Affected Lender's increased costs for
which it is entitled to reimbursement under this Agreement through the date of
such prepayment), and terminate such Affected Lender's obligations under the
Revolving Loan Commitment and Term Loan B Commitment.

                  (b) In the case of a Non-Funding Lender pursuant to SECTION
8.5(A), at Borrower's request, Agent or a Person acceptable to Agent shall have
the right with Agent's consent and in Agent's sole discretion (but shall have no
obligation) to purchase from any Non-Funding Lender, and each Non-Funding Lender
agrees that it shall, at Agent's request, sell and assign to Agent or such
Person, all of the Loans and Commitments of that Non-Funding Lender for an
amount equal to the principal balance of all Loans held by such Non-Funding
Lender and all accrued interest and Fees with respect thereto through the date
of sale, such purchase and sale to be consummated pursuant to an executed
Assignment Agreement.

                  (c) If, in connection with any proposed amendment,
modification, waiver or termination pursuant to SECTION 9.2 (a "PROPOSED
CHANGE"):

                           (i) requiring the consent of all affected Lenders,
the consent of Requisite Lenders is obtained, but the consent of other Lenders
whose consent is required is not obtained (any such Lender whose consent is not
obtained as described in this clause (i) and in clause (ii) below being referred
to as a "NON-CONSENTING LENDER"), or

(ii) requiring the consent of Supermajority Revolving Lenders, the consent of
Requisite Revolving Lenders is obtained, but the consent of Supermajority
Revolving Lenders is not obtained,

                                       78

 then, so long as Agent is not a Non-Consenting Lender, at Borrower's request
Agent, or a Person reasonably acceptable to Agent, shall have the right with
Agent's consent and in Agent's sole discretion (but shall have no obligation) to
purchase from such Non-Consenting Lenders, and such Non-Consenting Lenders agree
that they shall, upon Agent's request, sell and assign to Agent or such Person,
all of the Loans and Commitments of such Non-Consenting Lenders for an amount
equal to the principal balance of all Loans held by the Non-Consenting Lenders
and all accrued interest and Fees and other Obligations owing with respect
thereto through the date of sale, such purchase and sale to be consummated
pursuant to an executed Assignment Agreement.

         9.20     DELIVERY OF TERMINATION STATEMENTS AND MORTGAGE RELEASES.
                  ---------------------------------------------------------

         On the Termination Date, and so long as no suits, actions proceedings,
or claims are pending or threatened against any Indemnitee asserting any
damages, losses or liabilities that are indemnified liabilities hereunder, Agent
shall deliver to Borrower termination statements, mortgage releases and other
documents necessary or appropriate to evidence the termination of the Liens
securing payment of the Obligations.

         9.21     SUBORDINATION OF INTERCOMPANY DEBT.
                  -----------------------------------

                  (a) Each Credit Party hereby agrees that any intercompany
Indebtedness or other intercompany payables or receivables, or intercompany
advances directly or indirectly made by or owed to such Credit Party by any
other Credit Party (collectively, "INTERCOMPANY DEBT"), of whatever nature at
any time outstanding shall be subordinate and subject in right of payment to the
prior payment in full in cash of the Obligations. Each Credit Party hereby
agrees that it will not, while any Event of Default is continuing, accept any
payment, including by offset, on any Intercompany Debt until the Termination
Date, in each case, except with the prior written consent of Agent.

                  (b) In the event that any payment on any Intercompany Debt
shall be received by a Credit Party other than as permitted by this SECTION 9.21
before the Termination Date, such Credit Party shall receive such payments and
hold the same in trust for, segregate the same from its own assets and shall
immediately pay over to, the Agent for the benefit of the Agent and Lenders all
such sums to the extent necessary so that Agent and the Lenders shall have been
paid in full, in cash, all Obligations owed or which may become owing.

                  (c) Upon any payment or distribution of any assets of any
Credit Party of any kind or character, whether in cash, property or securities
by set-off, recoupment or otherwise, to creditors in any liquidation or other
winding-up of such Credit Party or in the event of any Proceeding, Agent and
Lenders shall first be entitled to receive payment in full in cash, in
accordance with the terms of the Obligations and of this Agreement, of all
amounts payable under or in respect of such Obligations, before any payment or
distribution is made on, or in respect of, any Intercompany Debt, in any such
Proceeding, any distribution or payment, to which Agent or any Lender would be
entitled except for the provisions hereof shall be paid by such Credit Party, or
by any receiver, trustee in bankruptcy, liquidating trustee, agent or other
person making such payment or distribution directly to Agent (for the benefit of
Agent and the Lenders) to the extent necessary to pay all such Obligations in
full in cash, after giving effect to any concurrent payment or distribution to
Agent and Lenders (or to Agent for the benefit of Agent and Lenders).

                                       79

         Witness the due execution hereof by the respective duly authorized
officers of the undersigned as of the date first written above.

                         PRIMEDEX HEALTH SYSTEMS, INC.
          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

     The unaudited pro forma condensed combined financial statements are based
on the historical consolidated statements of Primedex after giving effect to the
merger with Radiologix, borrowings used to finance the merger and the
assumptions and adjustments described in the attached to the unaudited pro forma
condensed combined financial statements.

     The unaudited pro forma condensed combined statement of operations is
prepared using the historical consolidated statements of operations of Primedex
for the year ended October 31, 2005 and the nine months ended July 31, 2006 and
the historical consolidated statements of operations of Radiologix for the year
ended December 31, 2005 and the nine months ended June 30, 2006 as if the merger
and borrowings to finance the merger occurred on November 1, 2004. The unaudited
pro forma condensed combined balance sheet is presented as if the merger and
borrowings used to finance the merger occurred on July 31, 2006 and combines the
unaudited condensed balance sheets of Primedex as of July 31, 2006 and
Radiologix as of June 30, 2006.

     The preliminary allocation of purchase price used in the unaudited pro
forma condensed combined financial statements is based upon preliminary
estimates. The estimates and assumptions are subject to change upon the
effective date of the merger and finalization of the valuation of Radiologix's
assets and liabilities. The unaudited pro forma condensed combined financial
statements do not include the effects of any anticipated operating efficiencies
or cost savings upon the merger. The unaudited pro forma condensed combined
financial statements are for illustrative purposes only, and are not necessarily
indicative of the consolidated results of operations or financial position of
Primedex that would have been reported had the merger and borrowings been
completed as of the dates presented, and should not be taken as representative
of the future consolidated results of operations or financial position of
Primedex. The pro forma adjustments are based on preliminary information
available at the time of the preparation of this document. Estimated valuation
of stock-based compensation included in the unaudited pro forma condensed
combined financial statement for the year ended October 31, 2005 for Primedex
and the year ended December 31, 2005 for Radiologix do not include the impact of
SFAS No. 123 (revised 2004) Share-Based Payment ("SFAS No. 123R").

     GE Healthcare Financial Services has provided a commitment for a $405.0
million of senior debt financing, which includes a $45.0 million revolving
credit facility for working capital and general corporate purposes that will be
substantially undrawn and available to Primedex at the close of the transaction.
The remaining $360.0 million will fund the cash purchase price of Radiologix and
refinance substantially all of the existing debt of Primedex and Radiologix.

     The unaudited pro forma condensed combined financial statements and the
accompanying notes are based upon the respective historical consolidated
financial statements of Primedex and Radiologix and should be read in
conjunction with the historical consolidated financial statements and
accompanying notes of Primedex and Radiologix included in this filing.

                    CONDENSED COMBINED FINANCIAL STATEMENTS

1.  BASIS OF PRO FORMA PRESENTATION

     On July 6, 2006, Primedex Health Systems, Inc. and Radiologix, Inc. entered
into a definitive agreement under which Primedex would merge with and into
Radiologix in a business combination to be accounted for using the purchase
method. The combined unaudited pro forma historical financial statements assume
the issuance of 22,621,922 shares of Primedex common stock and $42,950,000 in
cash. The average market price per share of Primedex common stock of
approximately $1.74 is based on the average closing price for June 28, 2006
through July 13, 2006.

     The estimated purchase price and the allocation of the estimated purchase
price discussed below are preliminary based on management's best estimate
because the proposed merger has not yet been completed and the final valuation
has not been completed. The final allocation of the purchase price will be based
on Radiologix's assets and liabilities on the closing date.

     The following notes to the unaudited pro forma condensed consolidated
financial statements give effect to the Radiologix merger as if it had occurred,
for balance sheet purposes, on July 31, 2006 and, for statement of operations
purposes, on November 1, 2004. The preliminary estimated total purchase price of
the merger is as follows:

                                   Annex D-6

     We have estimated the fair value of tangible assets acquired and
liabilities assumed. Some of these estimates are subject to change, particularly
those estimates relating to the valuation of property and equipment and
identifiable intangible assets. The allocation of the purchase price is
preliminary and based upon management's best estimate because the proposed
merger has not yet been completed and the final valuation has not been
completed. The final allocation of the purchase price will be based upon
Radiologix's assets and liabilities on the closing date and the allocation of
the purchase price will be reviewed by an external valuation expert.

     CASH, MARKETABLE SECURITIES, INVESTMENTS AND OTHER ASSETS: Primedex values
cash, marketable securities, investments and other assets at their respective
carrying amounts as Primedex believes that these amounts approximate their
current fair values or the fair values.

     IDENTIFIABLE INTANGIBLE ASSETS. Primedex expects identifiable intangible
assets acquired to include management service agreements. Management service
agreements represent the underlying relationships and agreements with certain
professional radiology groups.

     Identifiable intangible assets consist of:

                                                                    ESTIMATED
                                      ESTIMATED     AMORTIZATION     ANNUAL
                                     FAIR VALUE       PERIOD       AMORTIZATION
                                   -------------   -------------   -------------
                                                   (IN THOUSANDS)
Management service agreements      $      59,034        25 years   $       2,361

     Primedex has determined the preliminary fair value of intangible assets
with limited discussions with Radiologix management and a review of certain
transaction-related documents prepared by Radiologix management.

     Estimated useful lives for the intangible assets were based on the average
contract terms, which are greater than the amortization period that will be used
for management contracts. Intangible assets are being amortized using the
straight-line method, considering the pattern in which the economic benefits of
the intangible assets are consumed.

     GOODWILL. Approximately $41,396,000 has been allocated to goodwill.
Goodwill represents the excess of the purchase price over the fair value of the
underlying net tangible and intangible assets. In accordance with SFAS No. 142,
Goodwill and Other Intangible Assets, goodwill will not be amortized but instead
will be tested for impairment at least annually. In the event that the
management of the combined company determines that the value of goodwill has
become impaired, the combined company will incur an accounting charge for the
amount of impairment during the fiscal quarter in which the determination is
made.

2.  PRO FORMA ADJUSTMENTS

     The following is a brief description of the preliminary adjustments which
may change as additional information is obtained. These adjustments are based on
management's best estimate. In addition, these adjustments include
reclassifications to conform the financial statement presentation of Radiologix
with Primedex.
