            severally, indemnify the Agent (and any sub-agent thereof), and each
            Lender, and each affiliate of any of the foregoing persons (each

            disbursements of any outside counsel for any Indemnitee, incurred by

            with, or as a result of (i) the execution or delivery of this
            Agreement, any other Loan Document or any agreement or instrument
            contemplated hereby or thereby, the performance by the parties
            hereto of their respective obligations hereunder or the consummation
            of the transactions contemplated hereby or thereby, (ii) any actual
            or alleged presence of Releases on or from any property owned or
            operated by any Borrower or any Non-Borrower Subsidiary, or any
            environmental liability related in any way to any Borrower or any
            Non-Borrower Subsidiary, or (iii) any actual or prospective claim,
            litigation, investigation or proceeding relating to any of the
            foregoing, whether based on contract, tort or any other theory,
            whether brought by a third party or by any Borrower or any
            Non-Borrower Subsidiary, and regardless of whether any Indemnitee is
            a party thereto, provided that such indemnity shall not, as to any
            Indemnitee, be available to the extent that such losses, claims,
            damages, liabilities or related expenses are determined by a court
            of competent jurisdiction by final and nonappealable judgment to
            have resulted from the gross negligence or willful misconduct of
            such Indemnitee, or breach of this Agreement by Indemnitee.

            (b) Waiver of Consequential Damages, Etc. To the fullest extent
            permitted by applicable law, each Borrower agrees that it shall not
            assert, and hereby waives, any claim against any Indemnitee, on any
            theory of liability, for special, indirect, consequential or
            punitive damages (as opposed to direct or actual damages) arising
            out of, in connection with, or as a result of, this Agreement, any

            distributed by it through telecommunications, electronic or other
            information transmission systems in connection with this Agreement

            or thereby.

      16. To the extent that any Loan Document, as of the date hereof, would
prohibit the payment of a "Subordinated Debt Payment" expressly permitted
pursuant to the Subordination Agreement, such Loan Document shall be deemed
amended accordingly to permit the payment thereof if made in accordance with the
terms of the Subordination Agreement. For purposes hereof, a "Subordinated Debt
Payment" means (i) reimbursement of out-of-pocket costs and expenses incurred by
RBS in the ordinary course of its administration of the Subordinated Loan (but
not enforcement of the rights or remedies thereunder), as provided in the RBS
Documents, (ii) any regularly scheduled payments of accrued and unpaid interest
pursuant to the Subordinated Loan (without giving effect to any acceleration or
other modification of any due date of the Subordinated Loan) and (iii) annual
Monitoring Fees (as defined in the RBS Documents.

      17. The Lenders recognize that as a result of the failed issuance of
additional equity interests, the Borrowers incurred certain expenses, and
additionally, in connection the Repurchase/Redemption, the Borrowers will incur
losses, (collectively, the "Repurchase Expenses and Losses"), in the maximum
amount of Eleven Million One Hundred Thousand and No/100 Dollars
($11,100,000.00), which will cause the Borrowers to incur negative Consolidated
Net Income for the fiscal quarter ending September 30, 2005, resulting in a
violation of Section 6.15(e) of the Loan Agreement. The Lenders hereby consent
to the Borrowers adding-back the Repurchase Expenses and Losses to the
Borrowers' operating income, solely for the purpose of calculating Consolidated
Net Income for the fiscal quarter ending September 30, 2005. As a result, the
Repurchase Expenses and Losses would also constitute (without duplication) an
add back to the Borrowers' EBITDA for the fiscal quarter ended September 30,
2005 and their Consolidated Net Income and EBITDA for any period which includes
such fiscal quarter. The consent by the Lenders to the above-referenced add-back
to the Borrowers Consolidated Net Income constitutes a one-time waiver of the
requirements of the Loan Agreement specific to the Repurchase/Redemption.
Nothing contained herein shall constitute a waiver of any other provision of the
Loan Agreement or any other Loan Document.

      18. EXHIBIT 5 attached to the Loan Agreement is hereby deleted in its
entirety, and EXHIBIT 5 attached to this Modification substituted in lieu
thereof.

      19. Simultaneously with the Borrowers' execution and delivery of this
Modification (and as a condition precedent to the effectiveness of this
Modification), the Borrowers shall (a) pay to the Agent (for the ratable benefit
of the Lenders), in immediately available funds, an administrative fee in the
amount of Twenty Five Thousand and No/100 Dollars ($25,000.00), which fee the
Borrowers acknowledge has been fully earned by the Lenders; (b) pay to the
Agent, in immediately available funds, all of the Agent's and Lenders' costs and
expenses associated with this Modification and the transactions referenced
herein or contemplated hereby, including, without limitation, the Agent's and
Lenders' reasonable legal fees and expenses; and (c) deliver to the Agent the
other documents, instruments and agreements referenced herein.

      20. The Borrowers hereby represent, warrant, acknowledge and agree that as
of the date hereof (a) the Revolving Facility has a current outstanding
principal balance of approximately Twenty-six Million Four Hundred Ninety-two
Thousand One Hundred Eighty-six and 81/100 Dollars ($26,492,186.81); (b) the
Swing Line Outstandings Amount is approximately Nine Hundred Ninety-eight
Thousand Seven Hundred Forty-five and 72/100 Dollars ($998,745.72); (c) the face

the Term Facility has a current outstanding principal balance of approximately
Fourteen Million Two Hundred Fifty Thousand and 00/100 Dollars ($14,250,000.00);
(e) after giving effect to the transactions contemplated hereby, there are no
set-offs or defenses against and no defaults under the Loan Agreement, any of
the Notes or any other

time, or both, would constitute a default under the Loan Agreement, any of the
Notes or any other Loan Document; (g) all of the representations and warranties
of the Borrowers contained in the Loan Agreement expressly qualified by a
"materiality" standard are true and correct in all respects as of the date
hereof, and all of the representations and warranties of the Borrowers contained

true and correct in all material respects as of the date hereof (except with
respect to those changes in facts and circumstances which are expressly
permitted by the terms of the Loan Agreement or to the extent that such
representations and warranties expressly relate solely to an earlier date),
unless the Borrowers are unable to remake and redate any such representation or
warranty, in which case the Borrowers have previously disclosed the same to the
Agent and the Lenders in writing, and such inability does not constitute or give
rise to an Event of Default; and (h) all schedules attached to the Loan
Agreement with respect to any particular representation and warranty of the
Borrowers set forth in the Loan Agreement (as modified) remain true, accurate
and complete, as updated in writing to the Agent as of the date of this

      21. The Borrowers, and their respective representatives, successors and
assigns, hereby jointly and severally, knowingly and voluntarily RELEASE,
DISCHARGE, and FOREVER WAIVE and RELINQUISH any and all claims, demands,
obligations, liabilities, defenses, affirmative defenses, setoffs,
counterclaims, actions, and causes of action of whatsoever kind or nature,
whether known or unknown, which they have, may have, or might have or may assert
now or in the future against the Agent and/or the Lenders directly or
indirectly, arising out of, based upon, or in any manner connected with any
transaction, event, circumstance, action, failure to act, or occurrence of any
sort or type, in each case related to, arising from or in connection with the
Loan, whether known or unknown, and which occurred, existed, was taken,
permitted, or begun prior to the date hereof (including, without limitation, any
claim, demand, obligation, liability, defense, counterclaim, action or cause of
action relating to or arising from the grant by the Borrowers to the Lenders of
a security interest in or encumbrance on collateral that is, was or may be
subject to, or an agreement by which the Borrowers are bound and which contains,
a prohibition on further mortgaging or encumbering the same). The Borrowers
hereby acknowledge and agree that the execution of this Modification by the
Agent and the Lenders shall not constitute an acknowledgment of or an admission
by the Agent and/or the Lenders of the existence of any such claims or of
liability for any matter or precedent upon which any liability may be asserted.

      22. Except as expressly set forth herein, nothing contained in this
Modification is intended to or shall otherwise act to nullify, discharge, or
release any obligation incurred in connection with the Notes, the Loan Agreement
and/or the other Loan Documents or to waive or release any collateral given by
the Borrowers to secure the Notes, nor shall this Modification be deemed or
considered to operate as a novation of the Notes, the Loan Agreement or the
other Loan Documents. Except to the extent of any express conflict with this
Modification or except as otherwise expressly contemplated by this Modification,
all of the terms and conditions of the Notes, the Loan Agreement and the other
Loan Documents shall remain in full force and effect, and the same are hereby
expressly approved, ratified and confirmed. In the event of any express conflict
between the terms and conditions of the Notes, the Loan Agreement or the other
Loan Documents and this Modification, this Modification shall be controlling and
the terms and conditions of such other documents shall be deemed to be amended
to conform with this Modification.

      23. If any term, condition, or any part thereof, of this Modification, the
Loan Agreement or of the other Loan Documents shall for any reason be found or
held to be invalid or unenforceable by any court or governmental agency of
competent jurisdiction, such invalidity or unenforceability shall not

                                       8
<PAGE>

affect the remainder of such term, provision or condition nor any other term,
provision, or condition of this Modification, the Loan Agreement and the other
Loan Documents, and this Modification, the Loan Agreement and the other Loan
Documents shall survive and be construed as if such invalid or unenforceable
term, provision or condition had not been contained therein.

      24. The Borrowers acknowledge that, at all times prior to and through the
date hereof, the Agent and the Lenders have acted in good faith and have
conducted themselves in a commercially reasonable manner in its relationship
with the Borrowers in connection with this Modification and in connection with
the obligations of the Borrowers to the Agent and the Lenders under the Loan;
the Borrowers hereby waiving and releasing any claims to the contrary.

      25. The Borrowers hereby acknowledge and agree that, from and after the
date hereof, all references to the "Loan Agreement" set forth in any Loan
Document shall mean the Loan Agreement, as modified pursuant to the First
Modification and this Modification, and that except as expressly modified
hereby, the Loan Agreement shall be and remain unchanged and in full force and
effect, and the same is hereby expressly approved, ratified and confirmed.

      26. The Borrowers acknowledge (a) that they have participated in the
negotiation of this Modification, and no provision of this Modification shall be
construed against or interpreted to the disadvantage of any party hereto by any
court or other governmental or judicial authority by reason of such party having
or being deemed to have structured, dictated or drafted such provision; (b) that
each has had access to an attorney of its choosing in the negotiation of the
terms of and in the preparation and execution of this Modification, and each has
had the opportunity to review, analyze, and discuss with its counsel this
Modification, and the underlying factual matters relevant to this Modification,
for a sufficient period of time prior to the execution and delivery hereof; (c)
that all of the terms of this Modification were negotiated at arm's length; (d)
that this Modification was prepared and executed without fraud, duress, undue
influence, or coercion of any kind exerted by any of the parties upon the
others; and (e) that the execution and delivery of this Modification by each of
the Borrowers is its free and voluntary act and deed for the purposes contained
herein.

      27. This Modification shall be governed by the laws of the State of
Maryland, and shall be binding upon and inure to the benefit of the parties
hereto and their respective successors and assigns.

      28. This Modification may be executed in any number of counterparts, each
of which shall be deemed an original and all of which together shall be deemed
one and the same instrument. Signature pages may be exchanged by facsimile and
each party hereto agrees to be bound by its facsimile signature.

      29. With the understanding that RBS and Citizens Bank have adverse
interests in connection with the Loan, and each has hired its own counsel to
represent its respective interests, the Borrowers, by executing this
Modification (i) acknowledge that RBS is the parent company of Citizens Bank,
(ii) waive any conflict that may arise from such relationship, and (iii)
acknowledge that Citizens Bank has treated, and shall continue to treat RBS as
if it were an unaffiliated third party subordinated creditor and has not, and
will not provide RBS with any preferential treatment.
