         As a material inducement to each Holder to enter into and perform its
obligations under this Agreement, the Company represents and warrants to each
Holder as follows:

5.1      ORGANIZATION AND EXISTENCE

         The Company is a corporation duly organized, validly existing and in
good standing under the laws of New York and is qualified to do business in such
other jurisdictions as the nature or conduct of its operations or the ownership
of its properties require such qualification. The Company does not own or lease
any property or engage in any activity in any jurisdiction that might require
qualification to do business as a foreign corporation in such jurisdiction and
where the failure to so qualify could reasonably be expected to have a Material
Adverse Effect or subject the Company to a material liability.

5.2      AUTHORIZATION

         (a) The Company has all requisite corporate power and authority (i) to
execute and deliver, and to perform and observe its obligations under, this
Agreement and the other documents contemplated hereby (collectively the
"Transaction Documents") to which it is a party, and (ii) to consummate the
transactions contemplated hereby and thereby.

                                       11

<PAGE>

         (b)      All corporate action on the part of the Company and the
directors and (except as to the approval of the Restated Certificate) the
stockholders of the Company necessary for the authorization, execution, delivery
and performance by the Company of the Transaction Documents and the transactions
contemplated therein, and for the authorization, issuance and delivery of the
Preferred Stock, has been taken.

5.3      BINDING OBLIGATIONS; NO MATERIAL ADVERSE CONTRACTS

         The Transaction Documents constitute valid and binding obligations of
the Company enforceable in accordance with their respective terms. The
execution, delivery and performance by the Company of the Transaction Documents
and compliance therewith will not result in any violation of and will not
conflict with, or result in a breach of any of the terms of, or constitute a
default, or accelerate or permit the acceleration of any rights or obligations,
under, any provision of state, local, federal or foreign law to which the
Company is subject, the Existing Certificate or the by-laws of the Company, or
any mortgage, indenture, agreement, instrument, judgment, decree, order, rule or
regulation or other restriction to which the Company is a party or by which it
is bound, and will not result in the creation of any mortgage, pledge, lien,
encumbrance or charge upon any of the properties or assets of the Company. No
stockholder of the Company has or will have any preemptive rights or rights of
first refusal by reason of the issuance of the Preferred Stock or the Common
Stock issuable upon conversion of the Preferred Stock.

5.4      FINANCIAL INFORMATION; SEC DOCUMENTS

         (a)      The Company has furnished to the Holders complete and correct

subsidiaries, including consolidated balance sheets as of December 31, 2002 and
2001 and consolidated statements of operations, changes in cash flows and
stockholders' equity, covering the three years ended December 31, 2002, all of
which statements have been certified by Grant Thornton LLP, independent
accountants within the meaning of the Securities Act and the rules and
regulations thereunder, and all of which statements are included or incorporated
by reference in the Company's Annual Report on Form 10-K for the fiscal year

the Exchange Act. Such financial statements have been prepared in conformity
with generally accepted accounting principles in the United States applied on a
consistent basis throughout the periods involved, except as otherwise stated
therein and fairly present the consolidated financial position of the Company
and its Subsidiaries as of the dates thereof and their consolidated results of
operations for such periods. The Company's auditors have raised no material
issues nor delivered any material correspondence with respect to any of the
Company's financial statements or financial affairs.

         (b)      The Company has also furnished to the Holders the unaudited
consolidated balance sheet of the Company and its subsidiaries as of September
30, 2003, and the related unaudited consolidated statements of operations,
consolidated statements of cash flow and consolidated statements of
stockholders' equity for the nine months ended September 30, 2003. Such
financial statements were prepared in conformity with generally accepted
accounting principles in the United States applied on a basis consistent with
the financial statements referred to in Section 5.4(a) and fairly present the
consolidated financial position of the Company and its

                                       12

such periods (subject to normal year-end adjustments).

         (c)      None of the documents filed by the Company with the Securities
and Exchange Commission since December 31, 1997 contain any untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary in order to make the statements contained therein not false or
misleading in light of the circumstances in which they were made. There are no
facts which the Company has not disclosed to the Holders which, individually or
in the aggregate, could reasonably be expected to have a Material Adverse
Effect.

         (d)      Except as set forth in the Company's Quarterly Report on Form
10-Q for the quarter ended September 30, 2003, since December 31, 2002, there
has been no Material Adverse Effect with respect to the Company and its
Subsidiaries.

5.5      OFFERING EXEMPTION

         (a)      None of the Company, its Affiliates or any Person acting on
its or their behalf has engaged or will engage, in connection with the offering
and issuance of the Preferred Stock, in any form in general solicitation or
general advertising within the meaning of Rule 502(c) under the Securities Act,
and none of the Company, or any of its Affiliates has, directly or indirectly,
solicited any offer to buy, sell or offer to sell or otherwise negotiate in
respect of, in the United States or to any United States citizen or resident,
any security which is or would be integrated with the sale of the Preferred
Stock in a manner that would require the Preferred Stock to be registered under
the Securities Act. Assuming the accuracy of the representations and warranties
given by the Holders in Article VI below, the offering and issuance of the
Preferred Stock have been, are, and will be exempt from registration under the
Securities Act, and such offering, sale and issuance is also exempt from
registration under applicable state securities and "blue sky" laws.

         (b)      The Company is not, nor upon consummation of the transactions
contemplated under the Transaction Documents, will it be, subject to
registration as an "investment company" under the 1940 Act.

5.6      DISCLOSURE

         The information heretofore provided and to be provided in connection
with this Agreement, including, without limitation, the Exhibits hereto, the
Transaction Documents and each of the agreements, documents, certificates and
writings previously furnished to the Holders or their representatives, do not
and will not contain any untrue statement of a material fact and do not and will
not omit to state a material fact necessary in order to make the statements and
writings contained herein and therein not false or misleading in the light of
the circumstances under which they were made. There are no facts that
(individually or in the aggregate) could reasonably be expected to have a
Material Adverse Effect, which has not been set forth herein or in the Company's
Annual Reports on Form 10-K for the fiscal year ended December 31, 2002, and/or
the Company's Quarterly Report on Form 10-Q for the nine months ended September

                                   ARTICLE VI

                  REPRESENTATIONS AND WARRANTIES OF THE HOLDERS

         As a material inducement to the Company to enter into and perform its
obligations under this Agreement, each Holder severally (as to itself and not
with respect to any other Holder) represents and warrants to the Company and
each other Holder as follows:

6.1      ORGANIZATION AND GOOD STANDING

         The Holder, if a corporation, partnership, trust or other form of
business entity, is duly organized, validly existing and in good standing under
the laws of the state of its incorporation, formation or organization, as the
case may be, and has, in all material respects, full power, authority and legal
right to own its properties and conduct its business as such properties are
presently owned and such business is presently conducted, and to execute,
deliver and perform its obligations under this Agreement.

6.2      DUE QUALIFICATION

         The Holder, if a corporation, partnership, trust or other form of
business entity, is duly qualified to do business and, where necessary, is in
good standing as a foreign corporation or company, as the case may be, (or is
exempt from such requirement) and has obtained all necessary licenses and
approvals in each jurisdiction in which the conduct of its business requires
such qualification except where the failure to so qualify or obtain licenses or
approvals would not have a material adverse effect on its ability to perform its
obligations hereunder.

6.3      DUE AUTHORIZATION

         The execution and delivery of this Agreement and the consummation of
the transactions provided for or contemplated by this Agreement have been duly
authorized by Holder if a corporation, partnership, trust or other form of
business entity, by all necessary corporate or company (as the case may be)
action on the part of Holder. Upon the effectiveness of this Agreement, the
Holder will be party to and bound by (i) this Agreement, (ii) the New Agency
Agreement, (iii) the New Registration Rights Agreement, (iv) the New
Subordination Agreement and (v) the New Voting Agreement, and each such
agreement shall be enforceable against the Holder in accordance with its terms.
Upon the Effective Time, the Holder will be party to and bound by the Investor
Rights Agreement and such agreement shall be enforceable against the Holder in
accordance with its terms.

6.4      INVESTMENT EXPERIENCE; ACCREDITED INVESTOR

         (a)      The Holder must bear the economic risk of investment in the
Preferred Stock for an indefinite period of time, since the Preferred Stock has
not been registered under the Securities Act or applicable state securities
laws, and, therefore, cannot be resold or otherwise disposed of unless either
they are subsequently registered under the Securities Act and applicable state
securities laws or an exemption from registration is available.

                                       14

<PAGE>

         (b)      The Holder will only have those limited rights to register the
shares issuable upon conversion of the Preferred Stock under the Securities Act
and applicable state securities laws as are provided in the New Registration
Agreement.

         (c)      The Holder and his, her or its purchaser representative(s), if
any, have carefully reviewed and understand the risks of and other
considerations relating to entering into this Agreement.

         (d)      The Holder and his, her or its purchaser representative(s), if
any, have been afforded the opportunity to obtain any information necessary to
verify the accuracy of any representations or information set forth in this
Agreement and have had all of their inquiries to the Company answered in full,
and have been furnished all requested materials relating to the Company and this
Agreement.

         (e)      Neither the Holder nor his, her or its purchaser
representative(s), if any, have been furnished any offering literature by the
Company or any of its Affiliates, other than this Agreement (including the
exhibits and attachments hereto), and the Holder has not received or heard any
print or electronic media advertising with respect to the Exchanges.

         (f)      The Holder is acquiring the Preferred Stock as principal for
its own investment account, and not (i) with a view to the resale or
distribution of all or any part thereof, or (ii) on behalf of another Person who
has not made the foregoing representations. The Holder agrees not to resell or
otherwise dispose of the Preferred Stock except as permitted by applicable law,
including, without limitation, any and all provisions of this Agreement and any
applicable regulation under the Securities Act or any state securities laws.

         (g)      The Holder is an "accredited investor," as defined in Rule
501(a) of Regulation D promulgated pursuant to the Securities Act.

         (h)      The Holder has evaluated the risks of investing in the Company
and has substantial experience in making investment decisions of this type or is
relying on his, her or its professional advisors or purchaser representative(s),
if applicable, in making this investment decision.

         (i)      The Holder understands the fundamental aspects of and risks
involved in an investment in the Company, including (i) the speculative nature
of the investment, (ii) the financial hazards involved, including the risk of
losing the entire investment, (iii) the lack of liquidity and the restrictions
on transferability of the Preferred Stock, (iv) the limited registration rights
regarding the shares issuable upon conversion of the Preferred Stock, and (v)
the fact that the Company has a history of losses and limited capital resources.

         (j)      The address set forth in Schedule I of this Agreement is the
Holder's true and correct principal address, and the Holder has no present
intention of becoming a resident of any other state or jurisdiction.

         (k)      The Holder, if a corporation, partnership, trust or other form
of business entity, has not been formed for the specific purpose of acquiring
the Preferred Stock.

                                       15

<PAGE>

         (l)      All of the information that the Holder has herein furnished to
the Company with respect to itself, its financial position, and its business and
investment experience, is correct and complete as of the date hereof.

         (m)      The Holder agrees to be bound by all of the terms and
conditions of the offering made by this Agreement and the exhibits and
attachments hereto.

         (n)      The Holder consents to the placement of a legend on any
certificate or other document evidencing the Preferred Stock stating that it has
not been registered under the Securities Act and setting forth or referring to
the restrictions on transferability and sale thereof. The Holder is aware that
the Company will make a notation in its appropriate records with respect to the
restrictions on the transferability of such securities.

The Holder acknowledges that the Company will rely upon the representations made
by such Holder in this Agreement in connection with the issuance of the
Preferred Stock to be issued hereunder.

understandings, written or oral, regarding the subject matter hereof and
thereof.

         No party may assign its rights or obligations under this Agreement
without the written consent of the Company and the holders of a majority of the

Agreement and the rights and obligations set forth herein shall inure to the
benefit of, and be binding upon the parties hereto, and each of their respective
successors, heirs and permitted assigns.

7.3      COUNTERPARTS

         This Agreement may be executed in any number of counterparts, including

         This Agreement and the rights of the parties hereunder shall be
governed in all respects by the laws of the State of New York wherein the terms
of this Agreement were negotiated,

                                       16

<PAGE>

excluding to the greatest extent permitted by law any rule of law that would
cause the application of the laws of any jurisdiction other than the State of
New York.

7.5      WAIVER OF JURY TRIAL

         EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL
BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT,
TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO ANY TRANSACTION DOCUMENT OR THE
ACTIONS OF ANY PARTY IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE OR
ENFORCEMENT THEREOF.

7.6      JURISDICTION

         (a)      Each of the parties hereto hereby irrevocably and
unconditionally submits, for itself and its property, to the nonexclusive
jurisdiction of any New York State court or United States Federal court sitting
in New York City, and any appellate court from any thereof, in any action or
proceeding arising out of or relating to this Agreement or any of the other
Transaction Documents to which it is a party or to whose benefit it is entitled,
or for recognition or enforcement of any judgment, and each of the parties
hereto irrevocably and unconditionally agrees that all claims in respect of any
such action or proceeding may be heard and determined in any such New York State
court or, to the fullest extent permitted by law, in such United States Federal
court. Each of the parties hereto agrees that a final judgment in any such
action or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on the right that any party may otherwise have to bring
any action or proceeding relating to this Agreement or any of the other
Transaction Documents in the courts of any other jurisdiction.

         (b)      Each of the parties hereto irrevocably and unconditionally
waives, to the fullest extent it may legally and effectively do so, any
objection that it may now or hereafter have to the laying of venue of any suit,
action or proceeding arising out of or in relation to this Agreement or any
other Transaction Document to which it is a party in any such New York State or
United States Federal court sitting in New York City. Each of the parties hereto
hereby irrevocably waives, to the fullest extent permitted by law, the defense
of an inconvenient forum to the maintenance of such action or proceeding in any
such court.

7.7      RIGHTS AND OBLIGATIONS; SEVERABILITY

         Unless otherwise expressly provided herein, each Holder's rights and
obligations hereunder are several rights and obligations, not rights and
obligations jointly held with any other Person. In case any provision of this
Agreement shall be invalid, illegal or unenforceable, the validity, legality and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.

7.8      SPECIFIC PERFORMANCE

         The rights and remedies of the parties hereto shall be cumulative. The
transactions contemplated by this Agreement are unique transactions and any
failure on the part of any party to complete the transactions contemplated by

in damages and the breach or threatened breach of the provisions of this
Agreement would cause the other parties hereto irreparable harm. Accordingly, in
addition to and not in limitation of any other remedies available to the parties
hereto for a breach or threatened breach of this Agreement, the parties shall be
entitled to seek specific performance of this Agreement and seek an injunction
restraining any such party from such breach or threatened breach.
