Dear Sirs:

         1.       INTRODUCTION.  ENZO BIOCHEM, INC., a New York corporation (the
"COMPANY"),  proposes to issue and sell to the purchasers, pursuant to the terms
of this  Placement  Agent  Agreement  (this  "AGREEMENT")  and the  Subscription
Agreements  in  the  form  of  EXHIBIT  A  attached  hereto  (the  "SUBSCRIPTION
AGREEMENTS")  entered  into  with  the  purchasers  identified  therein  (each a
"PURCHASER" and collectively, the "PURCHASERS"), up to an aggregate of 3,285,715
shares of common  stock,  $0.01 par value per share (the "COMMON  STOCK") of the
Company. The aggregate of 3,285,715 shares so proposed to be sold is hereinafter
referred to as the  "STOCK." The Company  hereby  confirms  its  agreement  with
Lazard Capital  Markets LLC to act as Placement  Agent ("LCM," or the "PLACEMENT
AGENT") in accordance with the terms and conditions hereof.

         2.       AGREEMENT TO ACT AS PLACEMENT AGENT;  PLACEMENT OF SECURITIES.
On the basis of the  representations,  warranties  and agreements of the Company
herein contained, and subject to all the terms and conditions of this Agreement:

                  2.1      The Company hereby  authorizes the Placement Agent to
         act as its exclusive agent to solicit offers for the purchase of all or
         part of the Stock from the  Company  in  connection  with the  proposed
         offering  of the Stock (the  "OFFERING").  Until the  Closing  Date (as
         defined in SECTION 4 hereof),  the Company shall not, without the prior
         written  consent of the  Placement  Agent,  solicit or accept offers to
         purchase  Stock  otherwise  than through the Placement  Agent.  LCM may
         utilize the  expertise of Lazard  Freres & Co. LLC in  connection  with
         LCM's placement agent activities.

                  2.2      The Placement Agent agrees,  as agent of the Company,
         to use  its  commercially  reasonable  efforts  to  solicit  offers  to
         purchase  the Stock from the  Company  on the terms and  subject to the
         conditions  set  forth  in  the  Prospectus  (as  defined  below).  The
         Placement Agent shall use commercially reasonable efforts to assist the
         Company in  obtaining  performance  by each  Purchaser  whose  offer to
         purchase Stock has been  solicited by the Placement  Agent and accepted
         by the Company,  but the Placement Agent shall not, except as otherwise
         provided in this  Agreement,  be  obligated to disclose the identity of
         any  potential  purchaser  or have any  liability to the Company in the
         event any such  purchase is not  consummated  for any reason.  Under no
         circumstances  will the  Placement  Agent be obligated to underwrite or
         purchase any Stock for its own account and, in soliciting  purchases of
         Stock,  the Placement Agent shall act solely as the Company's agent and
         not as principal. Notwithstanding the foregoing and except as otherwise
         provided in SECTION 2.3, it is understood and agreed that the Placement
         Agent (or its affiliates) may, solely at its discretion and



         without any  obligation  to do so,  purchase  Stock as principal on the
         same terms as the other Purchasers.

                  2.3      Subject to the  provisions  of this SECTION 2, offers
         for the purchase of Stock may be solicited  by the  Placement  Agent as
         agent  for  the  Company  at such  times  and in  such  amounts  as the
         Placement Agent deems advisable.  The Placement Agent shall communicate
         to the Company, orally or in writing, each reasonable offer to purchase
         Stock  received by it as agent of the Company.  The Company  shall have
         the sole right to accept  offers to  purchase  the Stock and may reject
         any such offer, in whole or in part. The Placement Agent shall have the
         right, in its discretion  reasonably  exercised,  without notice to the
         Company, to reject any offer to purchase Stock received by it, in whole
         or in part, and any such rejection  shall not be deemed a breach of its
         agreement contained herein.

                  2.4      The Stock is being sold to the  Purchasers at a price
         of $14.00 per share. The purchases of the Stock by the Purchasers shall
         be evidenced by the execution of Subscription Agreements by each of the
         Purchasers and the Company.

                  2.5      As compensation for services rendered, on the Closing
         Date (as  defined in SECTION 4 hereof),  the  Company  shall pay to the
         Placement  Agent by wire transfer of immediately  available funds to an
         account or accounts  designated  by the Placement  Agent,  an aggregate
         amount equal to five and one half percent  (5.5%) of the gross proceeds
         received  by the  Company  from the sale of the  Stock on such  Closing
         Date.

                  2.6      No  Stock  which  the  Company  has  agreed  to  sell
         pursuant to this  Agreement  shall be deemed to have been purchased and
         paid for,  or sold by the  Company,  until such  Stock  shall have been
         delivered to the Purchaser  thereof  against payment by such Purchaser.
         If the Company shall default in its  obligations  to deliver Stock to a
         Purchaser whose offer it has accepted,  the Company shall indemnify and
         hold the Placement Agent harmless  against any loss,  claim,  damage or
         expense  arising  from or as a result of such default by the Company in
         accordance with the procedures set forth in Section 8(c) herein.

         3.       REPRESENTATIONS  AND  WARRANTIES  OF THE COMPANY.  The Company
represents  and  warrants  to,  and agrees  with,  the  Placement  Agent and the
Purchasers that:

                  (a)      The Company has prepared and filed in conformity with
         the  requirements  of the  Securities  Act of  1933,  as  amended  (the
         "SECURITIES ACT"), and published rules and regulations  thereunder (the
         "RULES  AND  REGULATIONS")  adopted  by  the  Securities  and  Exchange
         Commission  (the  "COMMISSION")  a "shelf"  Registration  Statement (as
         hereinafter  defined) on Form S-3 (File No.  333-138417),  which became
         effective as of December 8, 2006 (the  "EFFECTIVE  DATE"),  including a
         base prospectus relating to the Stock (the "BASE PROSPECTUS"), and such
         amendments  and  supplements  thereto as may have been  required to the
         date of this Agreement.  The term  "REGISTRATION  STATEMENT" as used in
         this  Agreement  means  the  registration   statement   (including  all
         exhibits,  financial schedules and all documents and information deemed
         to be a part of the Registration  Statement pursuant to Rule 430A under
         the Securities Act), as amended and/or supplemented to the date of this
         Agreement, including the Base Prospectus. The Registration Statement is
         effective  under the  Securities  Act and no stop order  preventing  or
         suspending  the   effectiveness  of  the   Registration   Statement  or
         suspending or preventing  the use of the  Prospectus has been issued by
         the Commission and no proceedings for that purpose have been instituted
         or, to the knowledge of the Company,  are threatened by the Commission.
         The  Company,   if  required  by  the  Rules  and  Regulations  of  the
         Commission,  will file the  Prospectus  (as  defined  below),  with the
         Commission  pursuant to Rule 424(b) of the Rules and  Regulations.  The
         term  "PROSPECTUS" as used in this Agreement  means the Prospectus,  in
         the form in which it is to be filed  with the  Commission  pursuant  to
         Rule 424(b) of the Rules and Regulations,  or, if the Prospectus is not
         to be filed with the Commission pursuant to Rule 424(b), the Prospectus
         in the form  included as part of the  Registration  Statement as of the
         Effective Date, except that if any revised prospectus or



         prospectus  supplement  shall be provided to the Placement Agent by the
         Company for use in  connection  with the offering and sale of the Stock
         which  differs  from  the  Prospectus  (whether  or  not  such  revised
         prospectus  or  prospectus  supplement  is  required to be filed by the
         Company pursuant to Rule 424(b) of the Rules and Regulations), the term
         "PROSPECTUS"  shall  refer to such  revised  prospectus  or  prospectus
         supplement,  as the case may be,  from and  after  the time it is first
         provided  to  the  Placement   Agent  for  such  use.  Any  preliminary
         prospectus  or  prospectus  subject  to  completion   included  in  the
         Registration  Statement or filed with the  Commission  pursuant to Rule
         424  under  the  Securities  Act is  hereafter  called  a  "PRELIMINARY
         PROSPECTUS." Any reference herein to the  Registration  Statement,  any
         Preliminary  Prospectus or the  Prospectus  shall be deemed to refer to
         and include the documents incorporated by reference therein pursuant to
         Item 12 of Form S-3 which were filed under the Securities  Exchange Act
         of 1934,  as amended  (the  "EXCHANGE  ACT"),  on or before the last to
         occur of the Effective Date, the date of the Preliminary Prospectus, or
         the date of the  Prospectus,  and any  reference  herein  to the  terms
         "amend,"  "amendment," or "supplement" with respect to the Registration
         Statement, any Preliminary Prospectus or the Prospectus shall be deemed
         to refer to and  include  (i) the  filing  of any  document  under  the
         Exchange Act after the  Effective  Date,  the date of such  Preliminary
         Prospectus or the date of the Prospectus,  as the case may be, which is
         incorporated  by reference and (ii) any such document so filed.  If the
         Company has filed an  abbreviated  registration  statement  to register
         additional  Stock  pursuant to Rule 462(b) under the Rules (the "462(b)
         REGISTRATION STATEMENT"), then any reference herein to the Registration
         Statement  shall also be deemed to  include  such  462(b)  Registration
         Statement.

         and its  Subsidiaries,  or (ii)  impair  in any  material  respect  the

         of the Company or any of its  Subsidiaries  other than those  described
         above or accurately  described in the General Disclosure  Package.  The
         description of the Company's stock option,  stock bonus and other stock
         plans  or  arrangements,  and  the  options  or  other  rights  granted
         thereunder,  as  described  in the General  Disclosure  Package and the
         Prospectus,  accurately and fairly present the information  required to
         be shown with respect to such plans, arrangements, options and rights.

                  (l)      All the  outstanding  shares of capital stock of each
         Subsidiary have been duly authorized and validly issued, are fully paid
         and  nonassessable  and,  except to the extent set forth in the General
         Disclosure Package or the Prospectus, are owned by the Company directly
         or indirectly through one or more wholly-owned  subsidiaries,  free and
         clear of any claim, lien, encumbrance,  security interest,  restriction
         upon voting or transfer or any other claim of any third party.

         Agreement,  the Subscription Agreements and the Escrow Agreement by the
         Company,  the  issue  and  sale of the  Stock  by the  Company  and the
         consummation of the transactions  contemplated  hereby and thereby will

         imposition of any lien, encumbrance, security interest, claim or charge

         to, any  indenture,  mortgage,  deed of trust,  loan agreement or other
         agreement or instrument to which the Company or any of its Subsidiaries
         is a party or by which the Company or any of its  Subsidiaries is bound
         or to which any of the  property or assets of the Company or any of its
         Subsidiaries is subject,  nor will such actions result in any violation
         of the  provisions  of the charter or by-laws (or  analogous  governing
         instruments,  as applicable) of the Company or any of its  Subsidiaries
         or any law, statute, rule, regulation, judgment, order or decree of any
         court or  governmental  agency or body,  domestic  or  foreign,  having

         prohibited activities" (as defined in Section 10A of the Exchange Act).

                  (p)      The financial  statements,  together with the related
         notes and  schedules,  included or  incorporated  by  reference  in the
         General  Disclosure  Package,  the Prospectus  and in the  Registration

         position  and the  results  of  operations  and  changes  in  financial
         position  of the Company and its  consolidated  subsidiaries  and other
         consolidated  entities at the  respective  dates or for the  respective
         periods  therein  specified.  Such  statements  and  related  notes and
         schedules have been prepared in accordance with the generally  accepted
         accounting  principles  in the  United  States  ("GAAP")  applied  on a

         General Disclosure Package. The financial statements, together with the
         related notes and schedules,  included or  incorporated by reference in
         the  General  Disclosure  Package  and  the  Prospectus  comply  in all
         material  respects with the  Securities  Act, the Exchange Act, and the

         are required by the Securities  Act or the Rules and  Regulations to be
         described, or included or incorporated by reference in the Registration
         Statement,  the General Disclosure Package or the Prospectus.  There is
         no pro forma or as adjusted financial  information which is required to
         be  included in the  Registration  Statement,  the  General  Disclosure
         Package, or and the Prospectus or a document  incorporated by reference
         therein  in  accordance  with  the  Securities  Act and the  Rules  and
         Regulations which has not been included or incorporated as so required.

         requirements  of the Securities Act and the Rules and  Regulations  and
         present fairly the information shown therein,  and the assumptions used
         in the  preparation  thereof are  reasonable and the  adjustments  used
         therein  are  appropriate  to  give  effect  to  the  transactions  and
         circumstances referred to therein.

                  (q)      Neither the Company nor any of its  Subsidiaries  has
         sustained,  since the date of the latest audited  financial  statements
         included  or  incorporated  by  reference  in  the  General  Disclosure
         Package, any material loss or interference with its business from fire,
         explosion,   flood  or  other  calamity,  whether  or  not  covered  by
         insurance,  or from any labor dispute or court or governmental  action,
         order or decree,  otherwise  than as set forth or  contemplated  in the
         General  Disclosure  Package;  and, since such date, there has not been
         any change in the capital stock or long-term debt of the Company or any
         of  its  Subsidiaries,   or  any  material  adverse  changes,   or  any
         development  involving a prospective  material  adverse  change,  in or
         affecting the business, assets, general affairs, management,  financial
         position,  prospects,  stockholders' equity or results of operations of
         the  Company  and its  Subsidiaries,  otherwise  than as set  forth  or
         contemplated in the General Disclosure Package.

                  (r)      Except  as  set  forth  in  the  General   Disclosure
         Package,  there is no  legal or  governmental  action,  suit,  claim or
         proceeding pending to which the Company or any of its Subsidiaries is a
         party or of which any  property  or assets of the Company or any of its
         Subsidiaries  is the subject  which is required to be  described in the
         Registration   Statement,   the  General   Disclosure  Package  or  the
         Prospectus or a document  incorporated by reference  therein and is not
         described  therein,  or  which,  singularly  or in  the  aggregate,  if
         determined  adversely to the Company or any of its Subsidiaries,  could
         have a Material  Adverse  Effect or  prevent  the  consummation  of the
         transactions  contemplated  hereby;  and to the  best of the  Company's
         knowledge,  no such  proceedings  are  threatened  or  contemplated  by
         governmental authorities or threatened by others.



                  (s)      Neither the Company nor any of its Subsidiaries is in
         (i)  violation  of its  charter  or  by-laws  (or  analogous  governing
         instrument,  as applicable),  (ii) default in any respect, and no event
         has  occurred  which,  with  notice  or lapse  of time or  both,  would
         constitute such a default,  in the due performance or observance of any
         term, covenant or condition contained in any indenture,  mortgage, deed
         of trust,  loan  agreement,  lease or other  agreement or instrument to
         which it is a party  or by  which  it is  bound or to which  any of its
         property or assets is subject or (iii)  violation in any respect of any
         law, ordinance, governmental rule, regulation or court order, decree or
         judgment to which it or its  property or assets may be subject  except,
         in the case of clauses  (ii) and (iii) of this  paragraph  (s), for any
         violations or defaults which, singularly or in the aggregate, would not
         have a Material Adverse Effect.

                  (t)      The Company and each of its Subsidiaries  possess all
         licenses, certificates,  authorizations and permits issued by, and have
         made all declarations and filings with, the appropriate  local,  state,
         federal or foreign regulatory agencies or bodies which are necessary or
         desirable for the ownership of its respective properties or the conduct
         of its  respective  businesses  as described in the General  Disclosure
         Package and the Prospectus  (collectively,  the "GOVERNMENTAL PERMITS")
         except where any failures to possess or make the same, singularly or in
         the aggregate,  would not have a Material  Adverse Effect.  The Company
         and its  Subsidiaries  is in  compliance  with  all  such  Governmental
         Permits;  all such Governmental Permits are valid and in full force and
         effect,  except  where the  validity or failure to be in full force and
         effect  would  not,  singularly  or in the  aggregate,  have a Material
         Adverse Effect. All such Governmental Permits are free and clear of any
         restriction  or  condition  that  are in  addition  to,  or  materially
         different   from  those  normally   applicable  to  similar   licenses,
         certificates,  authorizations and permits.  Neither the Company nor any
         subsidiary has received  notification of any revocation or modification
         (or proceedings  related thereto) of any such  Governmental  Permit and
         the Company has no reason to believe that any such Governmental  Permit
         will not be renewed.

                  (u)      Neither the Company  nor any of its  Subsidiaries  is
         or,  after  giving  effect  to  the  offering  of  the  Stock  and  the
         application  of the  proceeds  thereof  as  described  in  the  General
         Disclosure  Package  and the  Prospectus,  will  become an  "investment
         company"  within the meaning of the Investment  Company Act of 1940, as
         amended, and the rules and regulations of the Commission thereunder.

                  (v)      Neither the  Company,  its  Subsidiaries  nor, to the
         Company's  knowledge,   any  of  the  Company's  or  its  Subsidiaries'
         officers,  directors or affiliates has taken or will take,  directly or
         indirectly,  any action designed or intended to stabilize or manipulate
         the price of any security of the  Company,  or which caused or resulted
         in, or which  might in the future  reasonably  be  expected to cause or
         result in,  stabilization  or manipulation of the price of any security
         of the Company.

                  (w)      The Company and its  Subsidiaries  own or possess the
         right to use all patents, trademarks, trademark registrations,  service
         marks, service mark registrations,  trade names, copyrights,  licenses,
         inventions, software, databases, know-how, Internet domain names, trade
         secrets  and  other  unpatented  and/or  unpatentable   proprietary  or
         confidential information, systems or procedures, and other intellectual
         property (collectively,  "INTELLECTUAL PROPERTY") necessary to carry on
         their respective businesses as currently conducted,  and as proposed to
         be conducted  and described in the General  Disclosure  Package and the
         Prospectus,  and the Company is not aware of any claim to the  contrary
         or any  challenge  by any other person to the rights of the Company and
         its  Subsidiaries  with respect to the foregoing  except for those that
         could not have a Material  Adverse Effect.  The  Intellectual  Property
         licenses described in the General Disclosure Package and the Prospectus
         are valid,  binding  upon,  and  enforceable  by or against the parties
         thereto in  accordance  to their  terms.  The  Company  and each of its
         Subsidiaries  have complied in all material respects with, and are not,
         to the Company's knowledge, in breach nor have received any asserted or
         threatened claim of breach of, any Intellectual  Property license,  and
         the Company has



         no knowledge of any breach or anticipated breach by any other person to
         any  Intellectual  Property  license.  The  Company's  and  each of its
         Subsidiaries'  businesses  as  now  conducted  and  as  proposed  to be
         conducted do not and will not, to the Company's knowledge,  infringe or
         conflict  with any patents,  trademarks,  service  marks,  trade names,
         copyrights,  trade secrets,  licenses or other Intellectual Property or
         franchise  right of any  person.  No claim  has  been  received  by the
         Company that makes  against the Company or any of its  Subsidiaries  an
         allegation of infringement by the Company or any of its Subsidiaries of
         any patent,  trademark,  service  mark,  trade name,  copyright,  trade
         secret,  license in or other  intellectual  property right or franchise
         right of any  person.  The Company  and each of its  Subsidiaries  have
         taken all  reasonable  steps to protect,  maintain  and  safeguard  its
         rights  in  all  Intellectual  Property,  including  the  execution  of
         appropriate   nondisclosure   and   confidentiality   agreements.   The
         consummation  of the  transactions  contemplated by this Agreement will
         not, to the Company's knowledge, result in the loss or impairment of or
         payment of any  additional  amounts  with  respect  to, nor require the
         consent of any other person in respect of, the  Company's or any of its
         Subsidiaries'   right  to  own,  use,  or  hold  for  use  any  of  the
         Intellectual  Property as owned, used or held for use in the conduct of
         the  businesses  as  currently  conducted.  The Company and each of its
         Subsidiaries has at all times taken reasonable steps to comply with all
         applicable  laws  relating  to  privacy,   data  protection,   and  the
         collection and use of personal information collected, used, or held for
         use by the  Company and any of its  Subsidiaries  in the conduct of the
         Company's and its Subsidiaries businesses. No claims have been received
         by the Company or any of its  Subsidiaries  alleging a violation of any
         person's  privacy  or  personal  information  or  data  rights  and the
         consummation of the transactions  contemplated  hereby will not, to the
         Company's knowledge, breach or otherwise cause any violation of any law
         related to  privacy,  data  protection,  or the  collection  and use of
         personal information collected, used, or held for use by the Company or
         any of its  Subsidiaries  in the conduct of the Company's or any of its
         Subsidiaries'  businesses.  The  Company  and each of its  Subsidiaries
         takes reasonable  measures to ensure that such information is protected
         against unauthorized access, use, modification, or other misuse.

                  (x)      Except  as  set  forth  in  the  General   Disclosure
         Package,  there is no  legal or  governmental  action,  suit,  claim or
         proceeding pending to which the Company or any of its Subsidiaries is a
         party or of which any  property  or assets of the Company or any of its
         Subsidiaries is the subject, including any proceeding before the United
         States Food and Drug  Administration  of the U.S.  Department of Health
         and Human  Services  ("FDA") or  comparable  federal,  state,  local or
         foreign  governmental  bodies (it being understood that the interaction
         between the Company and the FDA and such comparable governmental bodies
         relating to the clinical development and product approval process shall
         not be deemed proceedings for purposes of this  representation),  which
         is required to be described in the Registration Statement,  the General
         Disclosure  Package or the  Prospectus  or a document  incorporated  by
         reference therein and is not described therein, or which, singularly or
         in the aggregate,  if determined adversely to the Company or any of its
         Subsidiaries,  could  reasonably be expected to have a Material Adverse
         Effect or prevent the  consummation  of the  transactions  contemplated
         hereby;  and  to the  Company's  Knowledge,  no  such  proceedings  are
         threatened or contemplated by governmental authorities or threatened by
         others.  The Company and its  Subsidiaries  is in  compliance  with all
         applicable federal, state, local and foreign laws, regulations,  orders
         and decrees  governing  its business as  prescribed  by the FDA, or any
         other federal,  state or foreign  agencies or bodies with  jurisdiction
         over the activities of the Company or its  Subsidiaries  engaged in the
         regulation of pharmaceuticals or biohazardous  substances or materials,
         except where noncompliance would not, singly or in the aggregate,  have
         a  Material  Adverse  Effect.  All  preclinical  and  clinical  studies
         conducted by or on behalf of the Company or its Subsidiaries to support
         approval for  commercialization  of the Company's or its  Subsidiaries'
         products have been conducted by the Company or its Subsidiaries,  or to
         the  Company's  knowledge  by third  parties,  in  compliance  with all
         applicable  federal,  state,  provincial or foreign laws, rules, orders
         and regulations, except for



         such failure or failures to be in compliance as could not reasonably be
         expected  to have,  singly  or in the  aggregate,  a  Material  Adverse
         Effect.

                  (y)      The Company and each of its Subsidiaries has good and
         marketable  title in fee simple  to, or have  valid  rights to lease or
         otherwise  use,  all  items  of real or  personal  property  which  are
         material to the business of the Company and its Subsidiaries,  free and
         clear  of all  liens,  encumbrances,  security  interests,  claims  and
         defects that do not, singularly or in the aggregate,  materially affect
         the value of such property and do not  interfere  with the use made and
         proposed  to be made  of such  property  by the  Company  or any of its
         Subsidiaries;  and all of the  leases  and  subleases  material  to the
         business  of the  Company  and its  Subsidiaries,  and under  which the
         Company or any of its Subsidiaries  holds  properties  described in the
         General  Disclosure  Package and the Prospectus,  are in full force and
         effect,  and neither the Company nor any  Subsidiary  has  received any
         notice  of any  material  claim of any sort that has been  asserted  by
         anyone adverse to the rights of the Company or any Subsidiary under any
         of the leases or subleases mentioned above, or affecting or questioning
         the  rights  of  the  Company  or  such  Subsidiary  to  the  continued
         possession of the leased or subleased  premises under any such lease or
         sublease.

                  (z)      No labor  disturbance by the employees of the Company
         or any of its  Subsidiaries  exists  or,  to the best of the  Company's
         knowledge, is imminent, and the Company is not aware of any existing or
         imminent  labor  disturbance  by  the  employees  of  any of its or its
         Subsidiaries'   principal   suppliers,   manufacturers,   customers  or
         contractors,  that could  reasonably be expected,  singularly or in the
         aggregate,  to have a Material Adverse Effect. The Company is not aware
         that any key employee or significant  group of employees of the Company
         or any Subsidiary plans to terminate employment with the Company or any
         such Subsidiary.

                  (aa)     No  "prohibited  transaction"  (as defined in Section
         406 of the Employee Retirement Income Security Act of 1974, as amended,
         including  the  regulations  and published  interpretations  thereunder
         ("ERISA"),  or Section  4975 of the Internal  Revenue Code of 1986,  as
         amended  from  time to  time  (the  "CODE"))  or  "accumulated  funding
         deficiency"  (as  defined in Section 302 of ERISA) or any of the events
         set forth in Section  4043(b) of ERISA  (other than events with respect
         to which the thirty (30)-day notice  requirement  under Section 4043 of
         ERISA has been waived) has occurred or could  reasonably be expected to
         occur with respect to any  employee  benefit plan of the Company or any
         of its Subsidiaries which could, singularly or in the aggregate, have a
         Material  Adverse Effect.  Each employee benefit plan of the Company or
         any of its Subsidiaries is in compliance in all material  respects with
         applicable  law,  including  ERISA and the Code.  The  Company  and its
         Subsidiaries  have not incurred and could not reasonably be expected to
         incur liability under Title IV of ERISA with respect to the termination
         of, or withdrawal  from,  any pension plan (as defined in ERISA).  Each
         pension  plan for which the  Company or any of its  Subsidiaries  would
         have any  liability  that is intended  to be  qualified  under  Section
         401(a) of the Code is so qualified,  and nothing has occurred,  whether
         by action or by  failure  to act,  which  could,  singularly  or in the
         aggregate, cause the loss of such qualification.

                  (bb)     The Company and its  Subsidiaries  are in  compliance
         with all foreign,  federal, state and local rules, laws and regulations
         relating to the use,  treatment,  storage and  disposal of hazardous or
         toxic  substances  or waste and  protection of health and safety or the
         environment  which are applicable to their  businesses  ("ENVIRONMENTAL
         LAWS"),  except where the failure to comply would not, singularly or in
         the  aggregate,  have a  Material  Adverse  Effect.  There  has been no
         storage, generation,  transportation,  handling,  treatment,  disposal,
         discharge,  emission,  or other  release  of any kind of toxic or other
         wastes  or other  hazardous  substances  by,  due to,  or caused by the
         Company or any of its Subsidiaries (or, to the Company's knowledge, any
         other  entity for whose  acts or  omissions  the  Company or any of its
         Subsidiaries  is or may  otherwise  be liable) upon any of the property
         now  or  previously  owned  or  leased  by  the  Company  or any of its
         Subsidiaries,  or upon any other  property,  in  violation  of any law,
         statute, ordinance, rule, regulation, order, judgment, decree or permit
         or which would, under any law, statute, ordinance,



         rule  (including  rule of common  law),  regulation,  order,  judgment,
         decree or permit, give rise to any liability,  except for any violation
         or liability which would not have,  singularly or in the aggregate with
         all such violations and  liabilities,  a Material  Adverse Effect;  and
         there has been no disposal, discharge, emission or other release of any
         kind  onto  such  property  or into the  environment  surrounding  such
         property  of any toxic or other  wastes or other  hazardous  substances
         with  respect to which the Company has  knowledge,  except for any such
         disposal, discharge, emission, or other release of any kind which would
         not have,  singularly or in the aggregate with all such  discharges and
         other releases,  a Material  Adverse Effect.  In the ordinary course of
         business,  the Company and its Subsidiaries conduct periodic reviews of
         the effect of Environmental  Laws on their business and assets,  in the
         course  of which  they  identify  and  evaluate  associated  costs  and
         liabilities  (including,  without limitation,  any capital or operating
         expenditures required for clean-up, closure of properties or compliance
         with Environmental Laws or Governmental Permits issued thereunder,  any
         related   constraints   on  operating   activities  and  any  potential
         liabilities  to  third  parties).  On the  basis of such  reviews,  the
         Company  and its  Subsidiaries  have  reasonably  concluded  that  such
         associated costs and liabilities  would not have,  singularly or in the
         aggregate, a Material Adverse Effect.

                  (cc)     The Company and its Subsidiaries, each (i) has timely
         filed all necessary federal,  state, local and foreign tax returns, and
         all such  returns were true,  complete  and correct,  (ii) has paid all
         federal, state, local and foreign taxes,  assessments,  governmental or
         other  charges  due and  payable  for  which it is  liable,  including,
         without  limitation,  all sales  and use taxes and all taxes  which the
         Company  or any of its  subsidiaries  is  obligated  to  withhold  from
         amounts owing to employees, creditors and third parties, and (iii) does
         not have any tax  deficiency or claims  outstanding  or assessed or, to
         the best of its knowledge,  proposed against any of them, except those,
         in each of the cases  described in clauses (i),  (ii) and (iii) of this
         PARAGRAPH (cc), that would not, singularly or in the aggregate,  have a
         Material Adverse Effect. The Company and its Subsidiaries, each has not
         engaged in any transaction  that could reasonably be characterized as a
         corporate  tax  shelter by the  Internal  Revenue  Service or any other
         taxing authority. The accruals and reserves on the books and records of
         the Company and its  Subsidiaries in respect of tax liabilities for any
         taxable  period not yet  finally  determined  are  adequate to meet any
         assessments and related liabilities for any such period, and since July
         31, 2006,  the Company and its  Subsidiaries  each has not incurred any
         liability for taxes other than in the ordinary course.

                  (dd)     The Company and each of its Subsidiaries  carries, or
         is covered by, insurance provided by recognized,  financially sound and
         reputable  institutions with policies in such amounts and covering such
         risks as is adequate for the conduct of their respective businesses and
         the  value of  their  respective  properties  and as is  customary  for
         companies  engaged in similar  businesses  in similar  industries.  The
         Company has no reason to believe that it or any Subsidiary  will not be
         able (i) to renew  its  existing  insurance  coverage  as and when such
         policies  expire or (ii) to obtain  comparable  coverage  from  similar
         institutions as may be necessary or appropriate to conduct its business
         as now  conducted  and at a cost that  would not  result in a  Material
         Adverse Effect.  Neither the Company nor any of its  Subsidiaries  have
         been denied any  insurance  coverage that they have sought or for which
         they have applied.

                  (ee)     The Company  and its  Subsidiaries  each  maintains a
         system of internal  accounting and other controls sufficient to provide
         reasonable  assurances that (i) transactions are executed in accordance
         with management's general or specific authorizations; (ii) transactions
         are recorded as necessary to permit preparation of financial statements
         in  conformity  with GAAP and to  maintain  accountability  for assets;
         (iii)  access  to  assets  is  permitted   only  in   accordance   with
         management's general or specific  authorization;  and (iv) the recorded
         accountability   for  assets  is  compared  with  existing   assets  at
         reasonable  intervals and  appropriate  action is taken with respect to
         any differences. Except as described in the General Disclosure Package,
         since the end of the Company's most recent  audited fiscal year,  there
         as been (A) no material weakness in the



         Company's  internal  control over financial  reporting  (whether or not
         remediated)  and (B) no change in the Company's  internal  control over
         financial  reporting  that has  materially  affected,  or is reasonably
         likely to  materially  affect,  the  Company's  internal  control  over
         financial reporting.

                  (ff)     The  minute  books  of the  Company  and  each of its
         Subsidiaries  have  been  made  available  to the  Placement  Agent and
         counsel for the Placement  Agent, and such books (i) contain a complete
         summary,  in all material respects,  of all meetings and actions of the
         board of directors (including each board committee) and shareholders of
         the Company (or analogous  governing  bodies and interest  holders,  as
         applicable),  and  each  of its  Subsidiaries  since  the  time  of its
         respective incorporation or organization through the date of the latest
         meeting  and  action,  and (ii)  accurately  in all  material  respects
         reflect all transactions referred to in such minutes.

                  (gg)     There is no franchise, lease, contract,  agreement or
         document required by the Securities Act or by the Rules and Regulations
         to be described in the General Disclosure Package and in the Prospectus
         or a document  incorporated  by reference  therein or to be filed as an
         exhibit to the  Registration  Statement or a document  incorporated  by
         reference  therein which is not described or filed therein as required;
         and  all  descriptions  of  any  such  franchises,  leases,  contracts,
         agreements or documents contained in the Registration Statement or in a
         document  incorporated  by reference  therein are accurate and complete
         descriptions of such documents in all material respects.  Other than as
         described in the General Disclosure Package, no such franchise,  lease,
         contract or agreement has been suspended or terminated for  convenience
         or default  by the  Company  or any of its  Subsidiaries  or any of the
         other  parties  thereto,  and  neither  the  Company  nor  any  of  its
         Subsidiaries  has  received  notice nor does the Company have any other
         knowledge of any such pending or threatened  suspension or termination,
         except for such pending or threatened  suspensions or terminations that
         would not  reasonably be expected to,  singularly or in the  aggregate,
         have a Material Adverse Effect.

                  (hh)     No relationship,  direct or indirect,  exists between
         or among the Company and any of its  Subsidiaries  on the one hand, and
         the directors, officers,  stockholders (or analogous interest holders),
         customers or suppliers of the Company or any of its Subsidiaries or any
         of  their  affiliates  on the  other  hand,  which  is  required  to be
         described in the General  Disclosure  Package and the  Prospectus  or a
         document  incorporated  by  reference  therein  and  which  is  not  so
         described.

                  (ii)     No  person  or  entity   has  the  right  to  require
         registration  of  shares  of Common  Stock or other  securities  of the
         Company  or  any  of  its   Subsidiaries   because  of  the  filing  or
         effectiveness  of the Registration  Statement or otherwise,  except for
         persons and entities who have expressly waived such right in writing or
         who have been given timely and proper written notice and have failed to
         exercise such right within the time or times  required  under the terms
         and  conditions  of such  right,  if any.  Except as  described  in the
         General  Disclosure  Package,  there are no persons  with  registration
         rights or  similar  rights  to have any  securities  registered  by the
         Company or any of its Subsidiaries under the Securities Act.

                  (jj)     Neither the Company nor any of its  Subsidiaries  own
         any "margin  securities" as that term is defined in Regulation U of the
         Board of Governors of the Federal Reserve System (the "FEDERAL  RESERVE
         BOARD"),  and none of the  proceeds  of the sale of the  Stock  will be
         used, directly or indirectly, for the purpose of purchasing or carrying
         any margin  security,  for the  purpose of  reducing  or  retiring  any
         indebtedness  which was  originally  incurred  to purchase or carry any
         margin  security or for any other  purpose which might cause any of the
         Stock to be  considered  a  "purpose  credit"  within the  meanings  of
         Regulation T, U or X of the Federal Reserve Board.

                  (kk)     Neither the Company nor any of its  Subsidiaries is a
         party to any contract,  agreement or understanding with any person that
         would give rise to a valid claim  against the Company or the  Placement
         Agent for a  brokerage  commission,  finder's  fee or like  payment  in



         connection  with the offering and sale of the Stock or any  transaction
         contemplated by this Agreement, the Registration Statement, the General
         Disclosure Package or the Prospectus.

                  (ll)     No  forward-looking  statement (within the meaning of
         Section 27A of the  Securities Act and Section 21E of the Exchange Act)
         contained in either the General  Disclosure  Package or the  Prospectus
         has been  made or  reaffirmed  without a  reasonable  basis or has been
         disclosed other than in good faith.

                  (mm)     The  Company is subject to and in  compliance  in all
         material  respects  with the  reporting  requirements  of Section 13 or
         Section  15(d) of the  Exchange  Act.  The Common  Stock is  registered
         pursuant  to  Section  12(b) of the  Exchange  Act and is listed on the
         NYSE,  and the Company has taken no action  designed to, or  reasonably
         likely to have the  effect  of,  terminating  the  registration  of the
         Common Stock under the Exchange Act or delisting  the Common Stock from
         the  NYSE,  nor has the  Company  received  any  notification  that the
         Commission  or the National  Association  of Securities  Dealers,  Inc.
         ("NASD") is contemplating  terminating such registration or listing. No
         consent, approval,  authorization or order of, filing,  notification or
         registration  with, the NYSE is required for the listing and trading of
         the Stock on the NYSE except as otherwise given or obtained.

                  (nn)     The  Company  is in  compliance  with all  applicable
         provisions  of the  Sarbanes-Oxley  Act  of  2002  and  all  rules  and
         regulations  promulgated  thereunder  or  implementing  the  provisions
         thereof (the "SARBANES-OXLEY ACT").

                  (oo)     The  Company  is  in  compliance  with  all  material
         applicable  corporate  governance  requirements  set  forth in the NYSE
         Rules.

                  (pp)     Neither the Company nor any of its Subsidiaries  nor,
         to the best of the  Company's  knowledge,  any employee or agent of the
         Company or any Subsidiary,  has made any  contribution or other payment
         to any  official of, or candidate  for,  any federal,  state,  local or
         foreign office in violation of any law  (including the Foreign  Corrupt
         Practices Act of 1977,  as amended) or of the character  required to be
         disclosed in the Registration Statement, the General Disclosure Package
         or the Prospectus or a document incorporated by reference therein.

                  (qq)     There  are no  transactions,  arrangements  or  other
         relationships  between and/or among the Company,  any of its affiliates
         (as such term is  defined  in Rule 405 of the  Securities  Act) and any
         unconsolidated  entity,  including,  but not limited to, any structured
         finance,   special   purpose  or  limited  purpose  entity  that  could
         reasonably be expected to materially affect the Company's or any of its
         Subsidiaries'  liquidity or the  availability  of or  requirements  for
         their  capital  resources  required  to be  described  in  the  General
         Disclosure  Package and the  Prospectus or a document  incorporated  by
         reference therein which have not been described as required.

                  (rr)     There  are no  outstanding  loans,  advances  (except
         normal  advances  for  business  expenses  in the  ordinary  course  of
         business) or  guarantees or  indebtedness  by the Company or any of its
         Subsidiaries  to or for the benefit of any of the officers or directors
         of the  Company,  any of its  Subsidiaries  or any of their  respective
         family members, except as disclosed in the Registration Statement,  the
         General Disclosure Package or the Prospectus.

                  (ss)     The  statistical  and market related data included in
         the  Registration  Statement,  the General  Disclosure  Package and the
         Prospectus  are  based on or  derived  from  sources  that the  Company
         believes  to be  reliable  and  accurate,  and such data agree with the
         sources from which they are derived.

                  (tt)     The  operations  of the Company and its  Subsidiaries
         are and have been conducted at all times in compliance  with applicable
         financial  recordkeeping and reporting requirements of the Currency and
         Foreign  Transactions  Reporting  Act of 1970,  as amended,  applicable
         money   laundering   statutes  and  applicable  rules  and  regulations
         thereunder (collectively,  the "MONEY LAUNDERING LAWS"), and no action,
         suit or proceeding by or before any court or governmental



         agency,  authority or body or any  arbitrator  involving the Company or
         any of its  Subsidiaries  with respect to the Money  Laundering Laws is
         pending, or to the best knowledge of the Company, threatened.

                  (uu)     Neither the Company nor any of its Subsidiaries  nor,
         to the knowledge of the Company, any director, officer, agent, employee
         or  affiliate  of the Company or any of its  Subsidiaries  is currently
         subject  to any U.S.  sanctions  administered  by the Office of Foreign
         Assets  Control  of the  U.S.  Treasury  Department  ("OFAC");  and the
         Company  will  not  directly  or  indirectly  use the  proceeds  of the
         offering, or lend, contribute or otherwise make available such proceeds
         to any Subsidiary, joint venture partner or other person or entity, for
         the purpose of financing the activities of any person currently subject
         to any U.S. sanctions administered by OFAC.

                  (vv)     Neither  the Company  nor any  Subsidiary  nor any of
         their   affiliates   (within   the   meaning  of  NASD   Conduct   Rule
         2720(b)(1)(a))  directly or indirectly controls,  are controlled by, or
         is under common  control with, or is an associated  person  (within the
         meaning of Article I, Section 1(ee) of the By-laws of the NASD) of, any
         member firm of the NASD.

                  (ww)     The  Company   satisfies  the  pre-1992   eligibility
         requirements  for the use of a  registration  statement  on Form S-3 in
         connection  with  the  Offering   contemplated   hereby  (the  pre-1992
         eligibility  requirements for the use of the registration  statement on
         Form S-3 include (i) having a non-affiliate, public common equity float
         of at least $150 million or a non-affiliate, public common equity float
         of at least $100  million and annual  trading  volume of at least three
         million  shares  and (ii)  having  been  subject  to the  Exchange  Act
         reporting requirements for a period of 36 months).

                  (xx)     No approval of the  shareholders of the Company under
         the rules and  regulations of NYSE is required for the Company to issue
         and deliver to the Purchasers the Stock.

Any  certificate  signed by or on behalf of the  Company  and  delivered  to the
Placement Agent or to counsel for the Placement Agent  specifically  pursuant to
this  Agreement  shall be  deemed to be a  representation  and  warranty  by the
Company to the  Placement  Agent and the  Purchasers  as to the matters  covered
thereby.

         4.       THE CLOSING.  The time and date of closing and delivery of the
documents required to be delivered to the Placement Agent pursuant to SECTIONS 5
and 7 hereof  shall be at 10:00 A.M.,  New York time,  on December 20, 2006 (the
"CLOSING DATE") at the office of Greenberg Traurig,  LLP, MetLife Building,  200
Park Avenue, New York, NY 10166.

         5.       FURTHER AGREEMENTS OF THE COMPANY. The Company agrees with the
Placement Agent and the Purchasers:

                  (a)      To prepare the  Prospectus  in a form approved by the
         Placement Agent containing  information  previously omitted at the time
         of  effectiveness  of the  Registration  Statement in reliance on rules
         430A, 430B and 430C and to file such Prospectus pursuant to Rule 424(b)
         under the Securities  Act not later than the second  business (2nd) day
         following  the  execution  and  delivery  of  this   Agreement  or,  if
         applicable,  such  earlier  time as may be required by Rule 430A of the
         Rules and Regulations; to notify the Placement Agent immediately of the
         Company's  intention to file or prepare any  supplement or amendment to
         any  Registration  Statement  or to  the  Prospectus  and  to  make  no
         amendment or  supplement  to the  Registration  Statement,  the General
         Disclosure  Package or to the  Prospectus to which the Placement  Agent
         shall  reasonably  object by notice to the Company  after a  reasonable
         period to review;  to advise the  Placement  Agent,  promptly  after it
         receives  notice  thereof,  of  the  time  when  any  amendment  to any
         Registration  Statement  has been  filed or  becomes  effective  or any
         supplement to the General  Disclosure  Package or the Prospectus or any
         amended  Prospectus  has been filed and to furnish the Placement  Agent
         copies thereof;  to file promptly all material  required to be filed by
         the Company with the



         Commission  pursuant to Rule 433(d);  to file  promptly all reports and
         any definitive proxy or information  statements required to be filed by
         the Company with the Commission pursuant to Section 13(a), 13(c), 14 or
         15(d) of the Exchange Act  subsequent to the date of the Prospectus and
         for so long as the delivery of a prospectus  (or in lieu  thereof,  the
         notice referred to in Rule 173(a) under the Securities Act) is required
         in  connection  with the  offering or sale of the Stock;  to advise the
         Placement  Agent,  promptly after it receives  notice  thereof,  of the
         issuance by the Commission of any stop order or of any order preventing
         or suspending the use of any  Preliminary  Prospectus,  any Issuer Free
         Writing  Prospectus  or  the  Prospectus,  of  the  suspension  of  the
         qualification of the Stock for offering or sale in any jurisdiction, of
         the  initiation or  threatening of any proceeding for any such purpose,
         or of any request by the Commission  for the amending or  supplementing
         of the Registration  Statement,  the General  Disclosure Package or the
         Prospectus  or for  additional  information;  and,  in the event of the
         issuance of any stop order or of any order preventing or suspending the
         use of any Preliminary  Prospectus,  any Issuer Free Writing Prospectus
         or the Prospectus or suspending any such qualification, and promptly to
         use its best efforts to obtain the withdrawal of such order.

                  (b)      The Company  represents  and agrees  that,  unless it
         obtains the prior consent of the Placement  Agent,  it has not made and
         will not, make any offer relating to the Stock that would  constitute a
         "free writing  prospectus"  as defined in Rule 405 under the Securities
         Act unless the prior written  consent of the  Placement  Agent has been
         received (each, a "PERMITTED FREE WRITING  PROSPECTUS");  PROVIDED that
         the prior written consent of the Placement Agent hereto shall be deemed
         to have been given in respect of the Issuer Free Writing Prospectus[es]
         included  in  SCHEDULE A hereto.  The  Company  represents  that it has
         treated  and  agrees  that it will treat each  Permitted  Free  Writing
         Prospectus  as an  Issuer  Free  Writing  Prospectus,  comply  with the
         requirements  of Rules 164 and 433 under the  Securities Act applicable
         to any Issuer  Free  Writing  Prospectus,  including  the  requirements
         relating to timely  filing with the  Commission,  legending  and record
         keeping and will not take any action that would result in the Placement
         Agent  or the  Company  being  required  to file  with  the  Commission
         pursuant  to  Rule  433(d)  under  the  Securities  Act a free  writing
         prospectus  prepared by or on behalf of such Placement  Agent that such
         Placement  Agent  otherwise  would  not  have  been  required  to  file
         thereunder.

                  (c)      If at any  time  when a  Prospectus  relating  to the
         Stock is required to be delivered  under the Securities  Act, any event
         occurs or condition exists as a result of which the Prospectus, as then
         amended  or  supplemented,  would  include  any untrue  statement  of a
         material  fact or omit to state a material  fact  necessary in order to
         make the statements  therein, in light of the circumstances under which
         they were made, not misleading,  or the Registration Statement, as then
         amended  or  supplemented,  would  include  any untrue  statement  of a
         material  fact or omit to state a material  fact  necessary to make the
         statements  therein not  misleading,  or if for any other  reason it is
         necessary at any time to amend or supplement any Registration Statement
         or the  Prospectus  to comply with the  Securities  Act or the Exchange
         Act, the Company will promptly notify the Placement Agent, and upon the
         Placement  Agent's request,  the Company will promptly prepare and file
         with the  Commission,  at the  Company's  expense,  an amendment to the
         Registration  Statement or an amendment or supplement to the Prospectus
         that corrects such statement or omission or effects such compliance and
         will deliver to the Placement  Agent,  without  charge,  such number of
         copies  thereof as the  Placement  Agent may  reasonably  request.  The
         Company  consents  to the use of the  Prospectus  or any  amendment  or
         supplement thereto by the Placement Agent.

                  (d)      If the  General  Disclosure  Package is being used to
         solicit  offers to buy the Stock at a time when the  Prospectus  is not
         yet available to prospective  purchasers and any event shall occur as a
         result of which,  in the  judgment of the Company or in the  reasonable
         opinion  of the  Placement  Agent,  it  becomes  necessary  to amend or
         supplement  the  General  Disclosure  Package  in  order  to  make  the
         statements  therein, in the light of the circumstances then prevailing,
         not



         misleading,  or to make the  statements  therein not conflict  with the
         information  contained or incorporated by reference in the Registration
         Statement  then on file and not  superseded  or  modified,  or if it is
         necessary  at any time to amend or  supplement  the General  Disclosure
         Package to comply with any law,  the Company  promptly  will either (i)
         prepare,  file with the  Commission  (if  required)  and furnish to the
         Placement Agent and any dealers an appropriate  amendment or supplement
         to the  General  Disclosure  Package or (ii)  prepare and file with the
         Commission an appropriate  filing under the Exchange Act which shall be
         incorporated by reference in the General Disclosure Package so that the
         General  Disclosure  Package as so amended or supplemented will not, in
         the  light of the  circumstances  then  prevailing,  be  misleading  or
         conflict with the  Registration  Statement then on file, or so that the
         General Disclosure Package will comply with law.

                  (e)      If at any time  following  issuance of an Issuer Free
         Writing  Prospectus there occurred or occurs an event or development as
         a result of which such Issuer Free  Writing  Prospectus  conflicted  or
         will  conflict  with  the  information  contained  in the  Registration
         Statement,  Pricing  Prospectus or  Prospectus,  including any document
         incorporated by reference therein and any prospectus  supplement deemed
         to be a part  thereof  and not  superseded  or  modified or included or
         would  include an untrue  statement  of a  material  fact or omitted or
         would omit to state a material  fact  required to be stated  therein or
         necessary in order to make the statements  therein, in the light of the
         circumstances  prevailing at the subsequent  time, not misleading,  the
         Company has promptly  notified or will  promptly  notify the  Placement
         Agent so that any use of the Issuer Free Writing  Prospectus  may cease
         until it is amended or  supplemented  and has promptly  amended or will
         promptly  amend or  supplement,  at its own  expense,  such Issuer Free
         Writing  Prospectus  to  eliminate  or correct  such  conflict,  untrue
         statement  or  omission.  The  foregoing  sentence  does  not  apply to
         statements in or omissions  from any Issuer Free Writing  Prospectus in
         reliance upon, and in conformity with, written information furnished to
         the Company by the Placement Agent  specifically for inclusion therein,
         which  information the parties hereto agree is limited to the Placement
         Agent's Information (as defined in SECTION -------- 17).

                  (f)      To the  extent  not  available  to the  public on the
         Commission's  EDGAR system,  to furnish promptly to the Placement Agent
         and  to  counsel  for  the  Placement   Agent  a  signed  copy  of  the
         Registration Statement as originally filed with the Commission,  and of
         each  amendment  thereto  filed  with  the  Commission,  including  all
         consents and exhibits filed therewith.

         shall  reasonably  request:  (i) conformed  copies of the  Registration

         excluding exhibits), (ii) each Preliminary Prospectus, (iii) any Issuer
         Free  Writing  Prospectus,  (iv) the  Prospectus  (the  delivery of the

         the  business  day   following  the  execution  and  delivery  of  this
         Agreement),  (v) conformed  copies of any amendment to the Registration

                  (h)      To make generally  available to its  shareholders  as
         soon as  practicable,  but in any event not later  than  eighteen  (18)

         Agent may designate and to continue such  qualifications in effect, and
         to comply  with such laws,  for so long as required to permit the offer
         and sale of Stock in such jurisdictions;  PROVIDED that the Company and
         its  Subsidiaries   shall  not  be  obligated  to  qualify  as  foreign
         corporations in any  jurisdiction in which they are not so qualified or
         to file a general consent to service of process in any jurisdiction.

                  (j)      Upon request, but only to the extent not available to
         the public on the Commission's EDGAR system,  during the period of five

         (90)  days  from the date of the  Prospectus,  (the  "LOCK-UP  PERIOD")

         of, any shares of Common Stock or any  securities  convertible  into or

         of Common Stock or any  securities  convertible  into or exercisable or
         exchangeable  for  Common  Stock,  not to  engage  in any swap or other
         agreement or arrangement that transfers,  in whole or in part, directly

         conference  with respect to the Company,  its  condition,  financial or

         for routine oral  marketing  communications  in the ordinary  course of

         consent of the Placement  Agent,  unless in the judgment of the Company
         and its counsel,  and after  notification to the Placement Agent,  such
         press release or communication is required by law.

                  (n)      Until the  Placement  Agent shall have  notified  the
         Company  of the  completion  of the  offering  of the  Stock,  that the
         Company will not, and will cause its affiliated  purchasers (as defined
         in  Regulation M under the Exchange  Act) not to,  either alone or with

         any Stock,  or attempt to induce any person to purchase any Stock;  and
         not to, and to cause its  affiliated  purchasers  not to,  make bids or
         purchase  for the  purpose of  creating  actual,  or  apparent,  active

         disclosed  to the  Company  on or prior to the  Closing  Date  that the
         Registration  Statement or any amendment or supplement thereto contains
         an untrue  statement of a fact which, in the opinion of counsel for the
         Placement  Agent,  is material or omits to state any fact which, in the
         opinion of such  counsel,  is  material  and is  required  to be stated
         therein or is necessary to make the statements  therein not misleading,
         or that  the  General  Disclosure  Package,  any  Issuer  Free  Writing
         Prospectus or the  Prospectus  or any  amendment or supplement  thereto
         contains  an untrue  statement  of fact  which,  in the opinion of such
         counsel,  is material or omits to state any fact which,  in the opinion
         of such  counsel,  is material  and is  necessary  in order to make the
         statements,  in the light of the circumstances in which they were made,
         not misleading.

                  (c)      All  corporate  proceedings  and other legal  matters

         Company, addressed to the Placement Agent and the

         satisfactory to the Placement Agent.

                  Such counsel shall also have furnished to the Placement  Agent
         a written  statement,  addressed to the  Placement  Agent and dated the
         Closing  Date,  in form and  substance  satisfactory  to the  Placement

         Company  in  connection  with  the  preparation  of  the   Registration
         Statement, the General Disclosure Package and the Prospectus,  and each
         amendment  or  supplement  thereto  made by the  Company  prior  to the
         Closing  Date,  (y)  based  on  such   counsel's   examination  of  the
         Registration   Statement,   the  General  Disclosure  Package  and  the
         Prospectus,  and  each  amendment  or  supplement  thereto  made by the
         Company  prior to the Closing Date and the  documents  incorporated  by
         reference in the General  Disclosure  Package or the Prospectus and any
         further amendment or supplement to any such incorporated  document made
         by  the  Company  prior  to  the  Closing  Date,   and  such  counsel's
         investigations   made  in  connection   with  the  preparation  of  the
         Registration   Statement,   the  General  Disclosure  Package  and  the
         Prospectus,  and  each  amendment  or  supplement  thereto  made by the
         Company  prior to the  Closing  Date,  and  "conferences  with  certain
         officers  and  employees  of and with  auditors  for and counsel to the
         Company,"   such  counsel  has  no  reason  to  believe  that  (I)  the
         Registration Statement or any amendment thereto, at the Applicable Time
         as of the date of this Agreement,  contained any untrue  statement of a
         material  fact or omitted to state any  material  fact  required  to be
         stated therein or necessary in order to make the statements therein not
         misleading,  or that the  Prospectus  or any  amendment  or  supplement
         thereto,  at  the  respective  date  thereof  or at the  Closing  Date,
         contained or contains any untrue  statement of a material fact or omits
         to state any material  fact  necessary in order to make the  statements
         therein,  in the light of the circumstances under which they were made,
         not  misleading,  the  documents  included  in the  General  Disclosure
         Package, all considered together,  as of the Applicable Time, contained
         or contains any untrue  statement of a material  fact or omits to state
         any material fact necessary in order to make the statements therein, in
         the  light  of the  circumstances  under  which  they  were  made,  not
         misleading,  or (II) any  document  incorporated  by  reference  in the
         Prospectus  or  any  further   amendment  or  supplement  to  any  such
         incorporated  document  made by the Company  prior to the Closing Date,
         when they became  effective or were filed with the  Commission,  as the
         case may be, contained,  in the case of a registration  statement which
         became  effective under the Securities  Act, any untrue  statement of a
         material  fact or omitted to state any  material  fact  required  to be
         stated therein or necessary in order to make the statements therein not
         misleading,  or, in the case of other  documents which were filed under
         the  Exchange  Act with  the  Commission,  any  untrue  statement  of a
         material fact or omitted to state any material fact  necessary in order
         to make the statements  therein,  in light of the  circumstances  under
         which they were made, not  misleading;  it being  understood  that such
         counsel need express no opinion as to the financial statements or other
         financial data  contained in the  Registration  Statement,  the General
         Disclosure Package, or the Prospectus, or an incorporated document. The
         foregoing  statement may be qualified by a statement to the effect that
         such counsel has not independently verified the accuracy,  completeness
         or fairness of the statements contained in the Registration  Statement,
         the  General   Disclosure  Package  or  the  Prospectus  and  takes  no
         responsibility  therefor  except to the extent set forth in the opinion
         described above.

         matters as the Placement Agent may reasonably require,  and the Company
         shall have furnished to such counsel such documents as they request for
         enabling them to pass upon such matters.

                  (h)      At the time of the execution of this  Agreement,  the
         Placement  Agent shall have  received  from Ernst & Young LLP a letter,
         addressed to the Placement Agent, executed and dated such date, in form
         and substance  satisfactory  to the Placement Agent (i) confirming that

         incorporated by reference in the  Registration  Statement,  the General
         Disclosure Package and the Prospectus.

                  (i)      On the effective date of any post-effective amendment
         to any  Registration  Statement and on the Closing Date,  the Placement
         Agent shall have received a letter (the "BRING-DOWN LETTER") from Ernst
         & Young LLP addressed to the Placement Agent and dated the Closing Date

         examined the Registration  Statement,  the General Disclosure  Package,
         any Permitted Free Writing  Prospectus and the Prospectus and, in their
         opinion, the Registration  Statement and each amendment thereto, at the
         Applicable  Time  and as of the  date of this  Agreement  and as of the
         Closing Date did not include any untrue  statement  of a material  fact
         and did not omit to state a material fact required to be stated therein

         Statement,  no event has occurred which should have been set forth in a
         supplement  or amendment  to the  Registration  Statement,  the General
         Disclosure  Package  or the  Prospectus,  (iii)  to the  best of  their

         subsequent to the date of the most recent audited financial  statements
         included  or  incorporated  by  reference  in  the  General  Disclosure
         Package,  any  material  adverse  change in the  financial  position or
         results of  operations  of the  Company  and its  Subsidiaries,  or any
         change or  development  that,  singularly  or in the  aggregate,  would
         involve a material  adverse  change or a prospective  material  adverse
         change, in or affecting



         the  condition   (financial  or  otherwise),   results  of  operations,
         business,  assets or  prospects  of the Company  and its  Subsidiaries,
         except as set forth in the Prospectus.

                  (k)      Since  the  date  of  the  latest  audited  financial

         Disclosure Package,  the effect of which, in any such case described in
         clause (i) or (ii) of this  PARAGRAPH  (k),  is, in the judgment of the
         Placement Agent, so material and adverse as to make it impracticable or
         inadvisable  to proceed  with the sale or  delivery of the Stock on the
         terms and in the manner contemplated in the General Disclosure Package.

                  (l)      No action shall have been taken and no law,  statute,

         change in general economic,  political or financial  conditions (or the
         effect of  international  conditions  on the  financial  markets in the
         United  States  shall be such) as to make it,  in the  judgment  of the
         Placement Agent,  impracticable or inadvisable to proceed with the sale
         or delivery of the Stock on the terms and in the manner contemplated in
         the General Disclosure Package and the Prospectus.

                  (n)      The NYSE shall have  approved the Stock for inclusion
         therein, subject only to official notice of issuance.

                  (o)      The  Placement  Agent shall have received the written

         have and shall not limit any rights or remedies  which may otherwise be
         available  at law or in  equity  to each  Placement  Agent  Indemnified
         Party.

                  (b)      The Placement Agent shall indemnify and hold harmless
         the Company and its directors, its officers who signed the Registration
         Statement and each person,  if any, who controls the Company within the
         meaning  of  Section  15 of the  Securities  Act or  Section  20 of the
         Exchange Act (collectively the "COMPANY INDEMNIFIED PARTIES" and each a
         "COMPANY INDEMNIFIED Party") against any loss, claim,  damage,  expense
         or liability whatsoever (or any action,  investigation or proceeding in
         respect thereof),  joint or several,  to which such Company Indemnified
         Party may  become  subject,  under  the  Securities  Act or  otherwise,
         insofar  as such  loss,  claim,  damage,  expense,  liability,  action,
         investigation  or  proceeding  arises  out of or is based  upon (i) any
         untrue  statement  or  alleged  untrue  statement  of a  material  fact
         contained  in any  Preliminary  Prospectus,  any  Issuer  Free  Writing
         Prospectus,  any  "issuer  information"  filed or  required to be filed
         pursuant to Rule 433(d) of the Rules and Regulations,  any Registration
         Statement or the Prospectus, or in any amendment or supplement thereto,
         or (ii) the  omission or alleged  omission to state in any  Preliminary
         Prospectus,   any  Issuer   Free   Writing   Prospectus,   any  "issuer
         information"  filed or required to be filed  pursuant to Rule 433(d) of
         the  Rules  and  Regulations,   any   Registration   Statement  or  the
         Prospectus,  or in any amendment or supplement thereto, a material fact
         required  to be stated  therein  or  necessary  to make the  statements
         therein  not  misleading,  but in each case only to the extent that the
         untrue  statement  or alleged  untrue  statement or omission or alleged
         omission  was made in  reliance  upon and in  conformity  with  written
         information   furnished   to  the  Company  by  the   Placement   Agent
         specifically  for use therein,  which  information  the parties  hereto
         agree is limited to the  Placement  Agent's  Information  as defined in
         SECTION  17, and shall  reimburse  the  Company  for any legal or other
         expenses   reasonably   incurred  by  such  party  in  connection  with
         investigating or preparing to defend or defending  against or appearing
         as third party witness in connection with any such loss, claim, damage,
         liability,  action,  investigation  or  proceeding,  as such  fees  and
         expenses are incurred.  Notwithstanding  the provisions of this Section
         8(b), in no event shall any indemnity by the Placement Agent under this
         Section 8(b) exceed the total  compensation  received by such Placement
         Agent in accordance with Section 2.5.

                  (c)      Promptly after receipt by an indemnified  party under
         this  SECTION  8 of  notice  of the  commencement  of any  action,  the
         indemnified  party shall,  if a claim in respect  thereof is to be made
         against an  indemnifying  party  under  this  SECTION  8,  notify  such
         indemnifying  party in  writing  of the  commencement  of that  action;
         PROVIDED,  HOWEVER,  that the failure to notify the indemnifying  party
         shall not  relieve it from any  liability  which it may have under this
         SECTION 8 except to the  extent it has been  materially  prejudiced  by
         such failure;  and,  PROVIDED,  FURTHER,  that the failure to notify an
         indemnifying party shall not relieve it from any liability which it may
         have to an  indemnified  party  otherwise than under this SECTION 8. If
         any such action shall be brought against an indemnified  party,  and it
         shall notify the indemnifying  party thereof,  the  indemnifying  party
         shall be entitled  to  participate  therein  and, to the extent that it
         wishes,  jointly with any other similarly notified  indemnifying party,
         to  assume  the  defense  of  such  action  with   counsel   reasonably
         satisfactory to the indemnified  party (which counsel shall not, except
         with the written  consent of the  indemnified  party, be counsel to the
         indemnifying  party).  After notice from the indemnifying  party to the
         indemnified party of its election to assume the defense of such action,
         except as provided herein,  the indemnifying  party shall not be liable
         to the indemnified party



         under SECTION 8 for any legal or other expenses  subsequently  incurred
         by the indemnified  party in connection with the defense of such action
         other than reasonable costs of investigation;  PROVIDED,  HOWEVER, that
         any indemnified  party shall have the right to employ separate  counsel
         in any such action and to participate in the defense of such action but
         the fees and expenses of such counsel (other than  reasonable  costs of
         investigation) shall be at the expense of such indemnified party unless
         (i) the employment thereof has been specifically  authorized in writing
         by the Company in the case of a claim for indemnification under SECTION
         8(a) or SECTION  2.6 or LCM in the case of a claim for  indemnification
         under SECTION 8(b), (ii) such indemnified party shall have been advised
         by its counsel that there may be one or more legal  defenses  available
         to it which are different from or additional to those  available to the
         indemnifying  party,  or (iii) the  indemnifying  party  has  failed to
         assume  the  defense  of such  action  and  employ  counsel  reasonably
         satisfactory  to the  indemnified  party within a reasonable  period of
         time after notice of the commencement of the action or the indemnifying
         party does not  diligently  defend the action after  assumption  of the
         defense,  in  which  case,  if  such  indemnified  party  notifies  the
         indemnifying party in writing that it elects to employ separate counsel
         at the expense of the indemnifying  party, the indemnifying party shall
         not have the  right to  assume  the  defense  of (or,  in the case of a
         failure  to  diligently  defend  the  action  after  assumption  of the
         defense,  to  continue  to  defend)  such  action  on  behalf  of  such
         indemnified  party and the indemnifying  party shall be responsible for
         legal or other expenses subsequently incurred by such indemnified party
         in connection with the defense of such action; PROVIDED,  HOWEVER, that
         the  indemnifying  party  shall not,  in  connection  with any one such
         action or separate but substantially  similar or related actions in the
         same  jurisdiction  arising  out of the  same  general  allegations  or
         circumstances,  be liable for the reasonable  fees and expenses of more
         than  one  separate  firm  of  attorneys  at  any  time  for  all  such
         indemnified  parties  (in  addition to any local  counsel),  which firm
         shall be designated in writing by LCM if the indemnified  parties under
         this SECTION 8 consist of any Placement Agent  Indemnified  Party or by
         the Company if the indemnified  parties under this SECTION 8 consist of
         any Company  Indemnified  Parties.  Subject to this SECTION  8(c),  the
         amount payable by an indemnifying  party under SECTION 8 shall include,
         but not be  limited  to, (x)  reasonable  legal  fees and  expenses  of
         counsel  to  the   indemnified   party  and  any  other   expenses   in
         investigating,   or  preparing  to  defend  or  defending  against,  or
         appearing as a third party witness in respect of, or otherwise incurred
         in connection with, any action, investigation, proceeding or claim, and
         (y)  all  amounts  paid  in  settlement  of any of  the  foregoing.  No
         indemnifying  party  shall,  without the prior  written  consent of the
         indemnified  parties,  settle or  compromise or consent to the entry of
         judgment with respect to any pending or threatened  action or any claim
         whatsoever,  in respect of which  indemnification or contribution could
         be sought under this SECTION 8 (whether or not the indemnified  parties
         are actual or  potential  parties  thereto),  unless  such  settlement,
         compromise  or consent (i)  includes an  unconditional  release of each
         indemnified party in form and substance reasonably satisfactory to such
         indemnified  party from all  liability  arising  out of such  action or
         claim and (ii) does not include a statement  as to or an  admission  of
         fault,  culpability  or a  failure  to  act  by or  on  behalf  of  any
         indemnified party. Subject to the provisions of the following sentence,
         no indemnifying  party shall be liable for settlement of any pending or
         threatened  action or any claim whatsoever that is effected without its
         written  consent (which consent shall not be  unreasonably  withheld or
         delayed),  but if settled with its written consent,  if its consent has
         been unreasonably withheld or delayed or if there be a judgment for the
         plaintiff  in  any  such  matter,  the  indemnifying  party  agrees  to
         indemnify and hold harmless any indemnified  party from and against any
         loss  or  liability  by  reason  of such  settlement  or  judgment.  In
         addition, if at any time an indemnified party shall have requested that
         an  indemnifying  party  reimburse the  indemnified  party for fees and
         expenses of counsel,  such  indemnifying  party agrees that it shall be
         liable for any settlement of the nature  contemplated  herein  effected
         without its written consent if (i) such settlement is entered into more
         than forty-five (45) days after receipt by such  indemnifying  party of
         the request for reimbursement,  (ii) such indemnifying party shall have
         received  notice of the terms of such  settlement  at least thirty (30)
         days  prior  to such  settlement  being  entered  into and  (iii)  such
         indemnifying  party shall not have



         reimbursed such indemnified party in accordance with such request prior
         to the date of such settlement.

                  (d)      If the indemnification provided for in this SECTION 8
         is unavailable or  insufficient  to hold harmless an indemnified  party
         under SECTION 8(a) or SECTION 8(b), then each indemnifying party shall,
         in lieu of  indemnifying  such  indemnified  party,  contribute  to the
         amount paid, payable or otherwise incurred by such indemnified party as
         a result of such loss,  claim,  damage,  expense or  liability  (or any
         action,  investigation or proceeding in respect thereof),  as incurred,
         (i) in such  proportion as shall be appropriate to reflect the relative
         benefits  received  by the  Company  on the one hand and the  Placement
         Agent on the other hand from the offering of the Stock,  or (ii) if the
         allocation provided by clause (i) of this SECTION 8(d) is not permitted
         by applicable  law, in such proportion as is appropriate to reflect not
         only the  relative  benefits  referred to in clause (i) of this SECTION
         8(d) but also the relative fault of the Company on the one hand and the
         Placement Agent on the other with respect to the statements, omissions,
         acts or failures to act which  resulted  in such loss,  claim,  damage,
         expense or liability  (or any action,  investigation  or  proceeding in
         respect   thereof)   as   well   as  any   other   relevant   equitable
         considerations.  The relative  benefits  received by the Company on the
         one hand and the  Placement  Agent on the other  with  respect  to such
         offering shall be deemed to be in the same  proportion as the total net
         proceeds from the offering of the Stock  purchased under this Agreement
         (before deducting  expenses)  received by the Company bear to the total
         discounts and commissions received by the Placement Agent in connection
         with the Offering,  in each case as set forth in the table on the cover
         page of the  Prospectus.  The relative  fault of the Company on the one
         hand and the  Placement  Agent on the  other  shall  be  determined  by
         reference to, among other things,  whether the untrue or alleged untrue
         statement  of a material  fact or the  omission or alleged  omission to
         state a material fact relates to information supplied by the Company on
         the one hand or the  Placement  Agent on the  other,  the intent of the
         parties  and  their  relative  knowledge,  access  to  information  and
         opportunity to correct or prevent such untrue statement,  omission, act
         or failure to act;  PROVIDED  that the  parties  hereto  agree that the
         written information furnished to the Company by the Placement Agent for
         use in the Preliminary  Prospectus,  any Registration  Statement or the
         Prospectus,  or in any amendment or supplement thereto, consists solely
         of the  Placement  Agent's  Information  as defined in SECTION  17. The
         Company  and the  Placement  Agent  agree that it would not be just and
         equitable  if  contributions  pursuant to this  SECTION 8(d) were to be
         determined by pro rata  allocation or by any other method of allocation
         that does not take into account the equitable  considerations  referred
         to herein.  The amount  paid or  payable by an  indemnified  party as a
         result  of  the  loss,  claim,  damage,  expense,  liability,   action,
         investigation  or  proceeding  referred to above in this  SECTION  8(d)
         shall be deemed to include,  for  purposes of this  SECTION  8(d),  any
         legal or other expenses  reasonably  incurred by such indemnified party
         in  connection  with  investigating,  preparing  to defend or defending
         against  or  appearing  as a third  party  witness  in  respect  of, or
         otherwise  incurred in connection with, any such loss,  claim,  damage,
         expense,    liability,    action,    investigation    or    proceeding.
         Notwithstanding  the  provisions  of this SECTION  8(d),  the Placement
         Agent shall not be required to  contribute  any amount in excess of the
         total  compensation  received by the Placement Agent in accordance with
         SECTION 2.5 less the amount of any damages  which the  Placement  Agent
         has  otherwise  paid or become liable to pay by reason of any untrue or
         alleged untrue statement,  omission or alleged omission, act or alleged
         act or failure to act or alleged  failure to act.  No person  guilty of
         fraudulent  misrepresentation  (within the meaning of Section  11(f) of
         the Securities Act) shall be entitled to  contribution  from any person
         who was not guilty of such fraudulent misrepresentation.

         9.       TERMINATION.  The  obligations of the Placement  Agent and the
Purchasers hereunder and under the Subscription  Agreements may be terminated by
the Placement  Agent, in its absolute  discretion by notice given to the Company
prior to delivery of and  payment for the Stock if,  prior to that time,  any of
the events  described in SECTIONS  7(k),  7(l),  or 7(m) have occurred or if the
Purchasers  shall decline to purchase the Stock for any reason  permitted  under
this Agreement or the Subscription Agreements.



         10.      REIMBURSEMENT OF PLACEMENT AGENT'S  EXPENSES.  Notwithstanding
anything to the contrary in this  Agreement,  if (a) this  Agreement  shall have
been terminated  pursuant to SECTION 9, (b) the Company shall fail to tender the
Stock for delivery to the  Purchasers  for any reason not  permitted  under this
Agreement, (c) the Purchasers shall decline to purchase the Stock for any reason
permitted  under this Agreement or (d) the sale of the Stock is not  consummated
because any  condition to the  obligations  of the  Purchasers  or the Placement
Agent set forth herein is not satisfied or because of the refusal,  inability or
failure on the part of the Company to perform any agreement herein or to satisfy
any condition or to comply with the provisions  hereof,  then in addition to the
payment of amounts in accordance with SECTION 6, the Company shall reimburse the
Placement  Agent for the fees and expenses of the Placement  Agent's counsel and
for such other out-of-pocket  expenses as shall have been reasonably incurred by
them in connection  with this Agreement and the proposed  purchase of the Stock,
and upon demand the Company  shall pay the full amount  thereof to the Placement
Agent.

         11.      ABSENCE OF FIDUCIARY  RELATIONSHIP.  The Company  acknowledges
and agrees that:

                  (a)      the Placement  Agent's  responsibility to the Company
         is solely  contractual in nature, the Placement Agent has been retained
         solely to act as Placement Agent in connection with the Offering and no
         fiduciary,  advisory or agency relationship between the Company and the
         Placement Agent has been created in respect of any of the  transactions
         contemplated by this  Agreement,  irrespective of whether the Placement
         Agent or Lazard Freres & Co. LLC has advised or is advising the Company
         on other matters;

                  (b)      the price of the  Stock  set forth in this  Agreement
         was  established by the Company  following  discussions and arms-length
         negotiations  with the Placement  Agent,  and the Company is capable of
         evaluating and understanding,  and understands and accepts,  the terms,
         risks  and  conditions  of  the   transactions   contemplated  by  this
         Agreement;

                  (c)      it has been  advised  that the  Placement  Agent  and
         Lazard  Freres & Co. LLC and their  affiliates  are  engaged in a broad
         range of  transactions  which may  involve  interests  that differ from
         those of the Company and that the Placement  Agent has no obligation to
         disclose such  interests and  transactions  to the Company by virtue of
         any fiduciary, advisory or agency relationship; and

                  (d)      it waives,  to the fullest  extent  permitted by law,
         any  claims it may have  against  the  Placement  Agent  for  breach of
         fiduciary  duty or alleged breach of fiduciary duty and agrees that the
         Placement Agent shall have no liability (whether direct or indirect) to
         the Company in respect of such a fiduciary  duty claim or to any person
         asserting  a  fiduciary  duty  claim  on  behalf  of or in right of the
         Company, including stockholders, employees or creditors of the Company.

         12.      SUCCESSORS;  PERSONS  ENTITLED TO BENEFIT OF  AGREEMENT.  This
Agreement shall inure to the benefit of and be binding upon the Placement Agent,
the Company, and their respective  successors and assigns.  This Agreement shall
also inure to the benefit of Lazard Freres & Co. LLC, the  Purchasers,  and each
of  their  respective  successors  and  assigns,  which  shall  be  third  party
beneficiaries  hereof.  Nothing  expressed  or  mentioned  in this  Agreement is
intended  or shall be  construed  to give any  person,  other  than the  persons
mentioned in the preceding  sentences,  any legal or equitable right,  remedy or

to the Company is solely  contractual in nature and the Placement Agent does not

Agreement.
