                          SECURITIES PURCHASE AGREEMENT

         This SECURITIES PURCHASE AGREEMENT ("Agreement") is made and entered
into as of the 12th day of December, 2003, by and between Contango Oil & Gas
Company, a Delaware corporation (the "Issuer"), and each of the persons listed
on Schedule 1 attached to this Agreement (each a "Purchaser" and collectively
the "Purchasers").

         WHEREAS, the Issuer desires to issue and to sell to the Purchasers, and
the Purchasers desire to purchase from the Issuer, the Series C Preferred Stock
(as hereinafter defined), all in accordance with the terms and provisions of
this Agreement; and

         NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties and covenants herein contained, the parties hereto
hereby agree as follows:

     1.  Agreement to Purchase  Securities.  Subject to the terms and conditions
hereinafter set forth in this Agreement,  each Purchaser hereby agrees severally
and not jointly to purchase at the  Closing,  and the issuer  agrees to sell and
issue to each  Purchaser  at the  Closing at a price of $5,000  per  share,  the
number of shares  of the  Issuer's  Series C  Cumulative  Convertible  Preferred
Stock,  par value  $0.04 per share  (the  "Series  C  Preferred  Stock"),  shown
opposite such  Purchaser's  name on Schedule 1, for an aggregate  purchase price
(the "Purchase Price") to be paid by such Purchaser in the amount shown opposite
such  Purchaser's  name on Schedule 1. The shares of the Issuer's  common stock,
par  value  $0.04 per  share  (the  "Common  Stock"),  that may be  issued  upon
conversion of the Series C Preferred Stock as  contemplated by the  Designations
Certificate (as defined below) are referred to herein as the "Converted Shares",
and the Series C  Preferred  Stock and the  Converted  Shares  are  collectively
referred to herein as the "Securities".

     2. Closing. Subject to the satisfaction or waiver of the conditions in this
Agreement,  the  purchase  and sale of the Series C  Preferred  Stock shall take
place at the offices of the Issuer at 3700 Buffalo Speedway, Suite 960, Houston,
Texas 77098,  at 10:00 a.m. (local time), on December 12, 2003, or at such other
time and place as the Issuer and the Purchasers acquiring,  in the aggregate,  a
majority of the shares of Series C Preferred  Stock to be sold  pursuant to this
Agreement agree upon orally or in writing (which time and date are designated as
the  "Closing").  At the Closing,  the Issuer shall deliver to each  Purchaser a
certificate  representing  the  shares of  Series C  Preferred  Stock  that such
Purchaser  is  purchasing  in the  name  and to the  address  specified  by each
Purchaser on Schedule 1 against  payment of the Purchase  Price therefor by wire
transfer of immediately available funds.

     3.  Purchasers'  Representations  and  Warranties.  Each  Purchaser  hereby
represents and warrants to the Issuer that:

          3.1  Investment  Intent.  Such  Purchaser is acquiring the  Securities
     solely for the  Purchaser's  own account for investment  purposes,  and not
     with a view to, or for offer or sale in connection  with, any  distribution
     of the  Securities in violation of the  Securities  Act of 1933, as amended
     (the "Securities Act"). By such  representation,  such Purchaser means that
     no other person has a beneficial  interest in the  Securities,  and that no
     other person has furnished or will furnish directly or indirectly, any part
     of or guarantee the payment of any part of the  consideration to be paid by
     such Purchaser to the Issuer in connection  therewith.  Such Purchaser does
     not  intend  to  dispose  of all or any part of the  Securities  except  in
     compliance  with the provisions of the Securities Act and applicable  state
     securities  laws,  and  understands  that the  Securities are being offered
     pursuant to a specific  exemption  under the  provisions of the  Securities
     Act, which exemption(s)  depends,  among other things, upon compliance with
     the provisions of the Securities Act.

                                       1


          3.2 Access to  Information.  Such Purchaser has received a copy of the
     Issuer's annual report on Form 10-KSB for the year ended June 30, 2003 (the
     "Annual  Report") and  quarterly  report on Form 10-Q for the quarter ended
     September  30,  2003  (the  "Quarterly   Report")  and  has  reviewed  them
     carefully,  including the risk factors set forth therein. In addition,  the
     Purchaser has received and reviewed a copy of the Issuer's proxy  statement
     for its annual meeting of stockholders held on November 7, 2003 (the "Proxy
     Statement").  If desired,  the  Purchaser has also sought and obtained from
     management  of  the  Issuer  such  additional  information  concerning  the
     business,  management and financial  affairs of the Issuer as the Purchaser
     has deemed  necessary or  appropriate  in  evaluating  an investment in the
     Issuer and determining whether or not to purchase the Securities.

          3.3  Accredited  Investor.   By  completing  the  Accredited  Investor
     Certification attached as Exhibit A, such Purchaser represents and warrants
     that it is an accredited investor,  as defined by Rule 501(a) of Regulation
     D under the Securities Act.

          3.4  Knowledge  and  Experience.  Such  Purchaser  is  experienced  in
     evaluating and investing in the securities of businesses in the development
     stage,  and has such  knowledge  and  experience  in financial and business
     matters  that it is  capable  of  evaluating  the  merits  and  risks of an
     investment in the  Securities and of protecting its interests in connection
     with an acquisition of the Securities.

          3.5 Suitability.  Such Purchaser has carefully considered, and has, to
     the extent the Purchaser deems it necessary, discussed with the Purchaser's
     own professional  legal,  tax and financial  advisers the suitability of an
     investment  in the  Securities  for  the  Purchaser's  particular  tax  and
     financial  situation,  and the Purchaser has determined that the Securities
     are a suitable investment for the Purchaser.

          3.6 Ability to Bear Risk of Loss.  Such Purchaser is financially  able
     to  hold  the  Securities  subject  to  restrictions  on  transfer  for  an
     indefinite  period of time,  and is capable of bearing the economic risk of
     losing up to the entire amount of its investment in the Securities.

          3.7 Non-Registered  Securities.  Such Purchaser  acknowledges that the
     offer  and  sale of the  Securities  have  not been  registered  under  the
     Securities  Act or any  state  securities  laws and the  Securities  may be
     resold only if registered  pursuant to the  provisions  thereunder or if an
     exemption from registration is available.  Such Purchaser  understands that
     the  offer  and  sale of the  Securities  is  intended  to be  exempt  from
     registration   under  the  Securities   Act,   based,  in  part,  upon  the
     representations,  warranties and agreements of such Purchaser  contained in
     this Agreement.

          3.8 Truth and Accuracy.  All  representations  and warranties  made by
     such  Purchaser  in this  Agreement  are true and  accurate  as of the date
     hereof and shall be true and accurate as of the date the Issuer  issues the
     Securities.  If at any time prior to the  issuance  of the  Securities  any
     representation  or warranty  shall not be true and accurate in any respect,
     such Purchaser shall so notify the Issuer.

          3.9  Authority.   The  individual(s)  executing  and  delivering  this
     Agreement on behalf of such Purchaser have been duly  authorized to execute
     and deliver this  Agreement on behalf of such  Purchaser,  the signature of
     such  individual(s) is binding upon such Purchaser,  such Purchaser is duly
     organized and subsisting under the laws of the jurisdiction in which it was
     organized,  and such  Purchaser was not formed for the specific  purpose of
     acquiring the Securities.

          3.10 No Violation.  The  execution and delivery of this  Agreement and
     the  consummation  of the  transactions  or performance of the  obligations
     contemplated by this Agreement do not and will not violate any term of such
     Purchaser's organizational documents.

                                       2


          3.11  Enforceability.  Such  Purchaser has duly executed and delivered
     this  Agreement and (subject to its execution by the Issuer) it constitutes
     a valid and binding  agreement of such Purchaser  enforceable in accordance
     with its terms against such Purchaser, except as such enforceability may be
     limited by  principles  of public  policy,  and  subject to laws of general
     application  relating to  bankruptcy,  insolvency and the relief of debtors
     and rules of law governing specific performance, injunctive relief or other
     equitable remedies.

          3.12 Reliance on Own Advisers.  In  connection  with such  Purchaser's
     investment in the Securities, such Purchaser has not relied upon the Issuer
     or its advisers for legal or tax advice, and has, if desired,  in all cases
     sought the advice of such Purchaser's own legal counsel and tax advisers.

          3.13  Scope  of  Business.   Such   Purchaser  has  been  advised  and
     understands  that  the  Issuer  will  be  exposed  to  numerous  investment
     opportunities  in all areas of the oil and gas industry  and may  therefore
     pursue various types of transactions and opportunities, even if they do not
     fit within the primary focus of the Issuer's  current  business  plan.  For
     example,  such transactions could include sales of all or substantially all
     of the Issuer's assets and such opportunities  could include  international
     investments  and downstream  investments in oil and gas service  companies,
     pipelines, and gas processing and gas storage facilities.

          3.14 Brokers or Finders.  Such Purchaser has not dealt with any broker
     or finder other than Energy  Capital  Solutions LLC in connection  with the
     transactions contemplated by the Agreement, and has not incurred, and shall
     not incur,  directly or  indirectly,  any  liability  for any  brokerage or
     finders' fees or agents  commissions  or any similar  charges in connection
     with the transactions contemplated by the Agreement.

          3.15 Short Sales. As of the date of this Agreement, such Purchaser and
     its  affiliates do not have, and during the 30 day period prior to the date
     of this Agreement such Purchaser and its affiliates  have not entered into,
     any "put  equivalent  position" as such term is defined in Rule 16a-1 under
     the  Securities  Exchange Act of 1934, as amended (the  "Exchange  Act") or
     short sale positions with respect to the Common Stock of the Issuer.  Until
     the  registration   statement  referred  to  in  Section  8.1  is  declared
     effective,  the  Purchaser  hereby  agrees  not  to,  and  will  cause  its
     affiliates not to, enter into any such "put  equivalent  position" or short
     sale position.

     4. Issuer's  Representations  and Warranties.  The Issuer hereby represents
and warrants to the Purchasers that:

          4.1 Corporate Existence;  Authority.  The Issuer is a corporation duly
     organized,  validly  existing  and in  good  standing  under  the  laws  of
     Delaware,  and it has all  requisite  power and  authority  to carry on its
     business as it is being conducted.  The individual executing and delivering
     this Agreement on behalf of the Issuer has been duly  authorized to execute
     and deliver this  Agreement on behalf of the Issuer,  and the  signature of
     such individual is binding upon the Issuer.

          4.2  Enforceability.  The Issuer has duly executed and delivered  this
     Agreement and (subject to its execution by the Purchasers) it constitutes a
     valid and binding  agreement of the Issuer  enforceable in accordance  with
     its terms against the Issuer,  except as such enforceability may be limited
     by principles of public policy, and subject to laws of general  application
     relating to  bankruptcy,  insolvency and the relief of debtors and rules of
     law governing  specific  performance,  injunctive relief or other equitable
     remedies.

          4.3 Capitalization.  The authorized capital of the Issuer consists, or
     will consist immediately prior to the Closing, of:

          outstanding,   (ii)  10,000  shares  have  been  designated  Series  B

               (b)  Common  Stock.  50,000,000  shares of Common  Stock of which

          have been duly and validly  issued and are fully paid,  non-assessable
          and not  subject to any  preemptive  or similar  rights.  The Series C
          Preferred Stock has been duly authorized and when issued and delivered
          to the  Purchasers  against  payment  therefor  as  provided  by  this
          Agreement,  will be validly  issued,  fully  paid and  non-assessable,

          Preferred  Stock  will not be  subject  to any  preemptive  or similar
          rights.  If and when issued,  the Converted Shares will have been duly
          authorized,  reserved for issuance  and,  when issued and delivered to

          validly  issued,  fully paid and  non-assessable,  and the issuance of
          such Converted Shares will not be subject to any preemptive or similar
          rights.

               (d) Prior to giving effect to the  transactions set forth herein,
          there are no outstanding subscriptions, options, warrants, convertible
          securities,  calls,  commitments,  agreements or rights to purchase or

          securities of the Issuer or to participate in any such registration.

          4.4 No  Conflicts.  The  issuance  and sale of the  Securities  to the
     Purchasers as  contemplated  hereby and the  performance  of this Agreement
     will not violate or conflict with the Issuer's Certificate of Incorporation
     or Bylaws or any  agreements  to which the Issuer is a party or by which it
     is otherwise  bound or, to the  Issuer's  knowledge,  any statute,  rule or
     regulation (federal, state, local or foreign) to which it is subject.

          4.5 SEC  Documents.  The Issuer has  provided the Annual  Report,  the
     Quarterly Report and the Proxy Statement to the Purchasers.  As of the date
     hereof,  the Annual Report, the Quarterly Report and the Proxy Statement do
     not  contain  any untrue  statement  of a material  fact or omit to state a
     material fact  required to be stated  therein or necessary in order to make
     the statements therein, in light of the circumstances under which they were
     made, not  misleading.  The financial  statements of the Issuer included in
     the Annual Report and the Quarterly Report financial statements dated as of
     September  30,  2003  heretofore  delivered  to the  Purchasers,  have been
     prepared  in  accordance  with  generally  accepted  accounting  principles
     applied on a consistent basis during the periods involved (except as may be
     indicated in the notes thereto) and fairly  present the financial  position
     of the Issuer as of the dates thereof and the results of its operations and
     cash flows for the  periods  then  ended.  The Issuer has  included  in the
     Annual  Report  a list of all  material  agreements,  contracts  and  other
     documents that it reasonably  believes are required to be filed as exhibits
     to the Annual Report.

          4.6 Litigation.  There is no litigation or other legal, administrative
     or  governmental  proceeding  pending or, to the  knowledge  of the Issuer,
     threatened against or relating to the Issuer or its properties or business,
     that if  determined  adversely to the Issuer may  reasonably be expected to
     have a  material  adverse  effect on the  present or future  operations  or
     financial condition of the Issuer.

          4.7 No  Material  Adverse  Change.  Since  the  date of the  Quarterly
     Report,  there has not been any material  adverse  change in the  business,
     operations,  properties, prospects, assets, or condition of the Issuer, and
     no event has  occurred  or  circumstance  exists  that may result in such a
     material adverse change.

          4.8 Environmental Matters.

               (a) Except as would not be  reasonably  likely to have a material

          liability  under  any  Environmental  Law  or  relating  to  Hazardous
          Substances;  and  (vii)  there  are  no  circumstances  or  conditions
          involving  Issuer that could  reasonably  be expected to result in any
          claims,  liability,  investigations,  costs  or  restrictions  on  the
          ownership,  use or transfer of any property of Issuer  pursuant to any
          Environmental Law.

     7. Restrictions on Transfer.

          7.1 Resale Restrictions.  The Purchasers understand that the offer and
     sale of the Securities to the Purchasers have not been registered under the
     Securities Act or under any state laws. Each Purchaser agrees not to offer,
     sell  or  otherwise  transfer  the  Securities,  or  any  interest  in  the
     Securities,  unless  (i)  the  offer  and  sale  is  registered  under  the
     Securities  Act,  the  Securities  may  be  sold  in  accordance  with  the
     applicable  requirements  and  limitations of Rule 144 under the Securities
     Act and any applicable state laws and, if the Issuer  reasonably  requests,
     such Purchaser delivers to the Issuer an opinion of counsel to such effect,
     or such Purchaser  delivers to the Issuer an opinion of counsel  reasonably
     satisfactory to the Issuer that the offer and sale is otherwise exempt from
     Securities Act registration. Notwithstanding the foregoing subsections (ii)
     and (iii), no opinion shall be required for transfers by a Purchaser to its
     affiliates.

          7.2 Restrictive Legend.  Each Purchaser  understands and agrees that a
     legend  in  substantially   the  following  form  will  be  placed  on  the
     certificates or other documents representing the Securities:

         "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
         UNDER ANY STATE SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD OR
         OTHERWISE TRANSFERRED UNLESS (i) THE OFFER AND SALE IS REGISTERED UNDER
         THE SECURITIES ACT, OR (ii) THE OFFER AND SALE IS EXEMPT FROM
         SECURITIES ACT REGISTRATION AND THE TERMS OF SECTION 7.1 OF THE
         SECURITIES PURCHASE AGREEMENT PURSUANT TO WHICH THE SECURITIES WERE
         ORIGINALLY PURCHASED HAVE BEEN COMPLIED WITH. (A COPY OF THE SECURITIES
         PURCHASE AGREEMENT IS ON FILE AT THE CORPORATE OFFICE OF THE
         CORPORATION.)"

                                       7


          7.3 Illiquid Investment. Each Purchaser acknowledges that it must bear
     the economic  risk of its  investment in the  Securities  for an indefinite
     period of time,  until such time as the  Securities  are  registered  or an
     exemption from registration is available.  Each Purchaser acknowledges that
     the soonest  that the Rule 144  exemption  from  registration  could become
     available  would  be  after  such  Purchaser  has  paid  for and  held  the
     Securities for one year.

     8.  Registration  of the Converted  Shares;  Compliance with the Securities
Act.

          8.1  Registration  Procedures  and Other  Matters.  The Issuer  shall:

               (a)  subject  to  receipt  of  necessary   information  from  the
          Purchasers  after prompt  request from the Issuer to the Purchasers to
          provide such information,  promptly following the Closing but no later
          than 60 days after the Closing (the "Filing  Date"),  prepare and file
          with the Securities and Exchange Commission (the "SEC") a registration
          statement on Form S-3 or such other successor form (except that if the
          Issuer is not then  eligible  to  register  for resale  the  Converted
          Shares on Form S-3, in which case such  registration  shall be on Form
          S-1 or any successor form) (a "Registration  Statement") to enable the
          resale of the Converted Shares, by the Purchasers or their transferees
          from  time  to  time  over  the   American   Stock   Exchange   or  in
          privately-negotiated   transactions.  No  Purchaser  may  include  any
          Converted  Share  in  the  Registration  Statement  pursuant  to  this
          Agreement  unless such  Purchaser  furnishes  to the Issuer in writing
          within five  business  days after  receipt of request  therefor,  such
          requested information;

               (b) use commercially  reasonable  efforts,  subject to receipt of
          necessary  information  from the Purchasers  after prompt request from
          the Issuer to the Purchasers to provide such information, to cause the
          Registration Statement to become effective as soon as practicable;

               (c)  use  its  commercially  reasonable  efforts  to  cause  such
          Registration  Statement to remain  continuously  effective and prepare
          and  file  with  the  SEC  such  amendments  and  supplements  to  the
          Registration Statement and the prospectus used in connection therewith
          (the   "Prospectus")   (and  the   applicable   Exchange  Act  reports
          incorporated therein by reference,  so filed on a timely basis) as may
          be necessary to keep the Registration Statement current, effective and
          free from any  material  misstatement  or omission to state a material
          fact for a period  ending on the date that is,  with  respect  to each
          Purchaser's  Converted Shares purchased hereunder,  the earlier of (i)
          the date on which the  Purchaser  may sell all  Converted  Shares then
          held by the Purchaser  without  restriction under Rule 144(k), or (ii)
          such time as all Converted  Shares purchased by such Purchaser in this
          Offering have been sold pursuant to a registration statement;

               (d) so long as a Purchaser holds Converted Shares, provide copies
          to and permit  single legal counsel  designated  by the  Purchasers to
          review the  Registration  Statement and all amendments and supplements
          thereto,  no fewer than three business days prior to their filing with
          the  SEC,  and not  file  any  Registration  Statement,  amendment  or
          supplement   thereto  to  which  a  holder  of  the  Converted  Shares
          reasonably objects in writing within such three business day period;

               (e)  furnish to the  Purchasers  with  respect  to the  Converted
          Shares  registered  under the  Registration  Statement  such number of
          copies of the  Registration  Statement,  Prospectuses  and preliminary
          Prospectuses    ("Preliminary    Prospectuses"    and    individually,
          "Preliminary  Prospectus") in conformity with the  requirements of the
          Securities  Act  and  such  other  documents  as  the  Purchasers  may
          reasonably  request,  in order to facilitate  the public sale or other
          disposition of all or any of the Converted  Shares by the  Purchasers;
          provided, however, that the obligation of the Issuer to deliver copies
          of Prospectuses or Preliminary Prospectuses to the Purchasers shall be
          subject to the receipt by the Issuer of reasonable assurances from the
          Purchasers  that  the  Purchasers  will  comply  with  the  applicable
          prospectus

                                       8


          delivery  requirements  under  the  Securities  Act and of such  other
          securities or blue sky laws as may be  applicable  in connection  with
          any use of such Prospectuses or Preliminary Prospectuses;

               (f) file  documents  required  of the Issuer for normal  blue sky
          clearance in states specified in writing by the Purchasers and use its
          commercially   reasonable   efforts   to   maintain   such   blue  sky
          qualifications  during the period the Issuer is  required  to maintain
          the  effectiveness of the Registration  Statement  pursuant to Section
          8.1(b);  provided,  however,  that the Issuer shall not be required to
          qualify  to do  business  or  consent  to  service  of  process in any
          jurisdiction  in  which  it is not  now  so  qualified  or has  not so
          consented;

               (g) promptly  notify the Purchasers  after it receives  notice of
          the time when the Registration  Statement has been declared  effective
          by the SEC, or when a  supplement  or  amendment  to any  Registration
          Statement has been filed with the SEC; and

               (h) advise the Purchasers,  promptly:  (a) after it shall receive
          notice or obtain  knowledge  of the  issuance of any stop order by the
          SEC  delaying or  suspending  the  effectiveness  of the  Registration
          Statement or of the  initiation or threat of any  proceeding  for that
          purpose; and it will promptly use its commercially  reasonable efforts
          to prevent the issuance of any stop order or to obtain its  withdrawal
          at the earliest  possible  moment if such stop order should be issued;
          and (b) at any time when a Prospectus  relating to Converted Shares is
          required to be delivered  under the  Securities  Act,  upon  discovery
          that,  or upon the  happening  of an event as a result of  which,  the
          Prospectus included in the Registration  Statement, as then in effect,
          includes an untrue  statement of a material fact or omits to state any
          material fact  required to be stated  therein or necessary to make the
          statements  therein not misleading in light of the circumstances  then
          existing.

     8.2 Transfer of Shares After Registration; Suspension.

               (a) Each Purchaser agrees that it will not effect any disposition
          of the  Converted  Shares  that  would  constitute  a sale  within the
          meaning  of  the  Securities  Act  except  as   contemplated   in  the
          Registration  Statement  referred to in Section  8.1 and as  described
          below or as  otherwise  permitted  by law,  and that it will  promptly
          notify the Issuer in writing  of any  changes in the  information  set
          forth in the  Registration  Statement  regarding  the Purchaser or its
          plan of distribution.

               (b) Except in the event that  paragraph  (c) below  applies,  the
          Issuer shall if deemed necessary by the Issuer,  prepare and file from
          time  to  time  with  the  SEC  a  post-effective   amendment  to  the
          Registration  Statement or a supplement to the related Prospectus or a
          supplement  or  amendment  to any  document  incorporated  therein  by
          reference   or  file  any  other   required   document  so  that  such
          Registration  Statement  will not  contain  an untrue  statement  of a
          material  fact or omit to state a material  fact required to be stated
          therein or necessary to make the statements  therein,  in light of the
          circumstances under which they were made, not misleading, and so that,
          as thereafter  delivered to  purchasers of the Converted  Shares being
          sold thereunder,  such Prospectus will not contain an untrue statement
          of a material  fact or omit to state a material  fact  required  to be
          stated therein or necessary to make the statements  therein,  in light
          of the circumstances under which they were made, not misleading,  (ii)
          provide  the  Purchasers  copies of any  documents  filed  pursuant to
          Section 8.2(b)(i), and (iii) inform each Purchaser that the Issuer has
          complied with its  obligations  in Section  8.2(b)(i) (or that, if the
          Issuer  has  filed  a  post-effective  amendment  to the  Registration
          Statement which has not yet been declared  effective,  the Issuer will
          notify  the  Purchasers  to that  effect,  will  use its  commercially
          reasonable efforts to secure the effectiveness of such  post-effective
          amendment  as  promptly  as  possible  and will  promptly  notify  the
          Purchaser  pursuant to Section 8.2(b)(i) hereof when the amendment has
          become effective).

                                       9


               (c) In the  event  (i) of any  request  by the  SEC or any  other
          federal  or  state   governmental   authority  during  the  period  of
          effectiveness  of  the   Registration   Statement  for  amendments  or
          supplements to a Registration  Statement or related  Prospectus or for
          additional  information;  (ii) of the issuance by the SEC or any other
          federal or state  governmental  authority of any stop order suspending
          the effectiveness of a Registration Statement or the initiation of any
          proceedings  for that  purpose;  (iii) of the receipt by the Issuer of
          any notification  with respect to the suspension of the  qualification
          or exemption  from  qualification  of any of the Converted  Shares for
          sale in any  jurisdiction  or the  initiation  or  threatening  of any
          proceeding  for such  purpose;  or (iv) of any  event or  circumstance
          which, upon the advice of its counsel,  necessitates the making of any
          changes in the Registration  Statement or Prospectus,  or any document
          incorporated  or deemed to be  incorporated  therein by reference,  so
          that, in the case of the Registration  Statement,  it will not contain
          any untrue  statement  of a material  fact or any  omission to state a
          material fact  required to be stated  therein or necessary to make the
          statements  therein  not  misleading,  and  that  in the  case  of the
          Prospectus,  it will not  contain any untrue  statement  of a material
          fact or any  omission to state a material  fact  required to be stated
          therein or necessary to make the statements  therein,  in the light of
          the circumstances under which they were made, not misleading, then the
          Issuer  shall  promptly  deliver  a  certificate  in  writing  to  the
          Purchasers  (the  "Suspension  Notice") to the effect of the foregoing
          and,  upon receipt of such  Suspension  Notice,  the  Purchasers  will
          refrain from selling any Converted Shares pursuant to the Registration
          Statement (a "Suspension")  until the Purchasers' receipt of copies of
          a supplemented or amended Prospectus prepared and filed by the Issuer,
          or until the  Purchasers are advised in writing by the Issuer that the
          current  Prospectus  may be used,  and  have  received  copies  of any
          additional or  supplemental  filings that are  incorporated  or deemed
          incorporated by reference in any such Prospectus.  In the event of any
          Suspension, the Issuer will use its commercially reasonable efforts to
          cause the use of the Prospectus so suspended to be resumed as promptly
          as  possible  after  the  delivery  of  a  Suspension  Notice  to  the
          Purchasers.

               (d)  Provided  that a  Suspension  is not  then  in  effect,  the
          Purchasers may sell Converted Shares under the Registration  Statement
          in the manner set forth under the caption  "Plan of  Distribution"  in
          the Prospectus,  provided that each arranges for delivery of a current
          Prospectus to the transferee of such Converted Shares. Upon receipt of
          a request  therefor,  the Issuer  has  agreed to  provide an  adequate
          number of current  Prospectuses to the Purchasers and to supply copies
          to any other parties requiring such Prospectuses.

     8.3 Indemnification. For the purpose of this Section 8.3:

               (i) the term "Selling  Stockholder"  shall include the Purchasers
          and their respective affiliates;

               (ii)  the  term   "Registration   Statement"  shall  include  the
          Prospectus  in the form  first  filed  with the SEC  pursuant  to Rule
          424(b)  of the  Securities  Act or filed  as part of the  Registration
          Statement  at the time of  effectiveness  if no Rule 424(b)  filing is
          required, any exhibit, supplement or amendment included in or relating
          to the Registration Statement referred to in Section 8.1; and

               (iii)  the term  "untrue  statement"  shall  include  any  untrue
          statement  or  alleged  untrue  statement  of a  material  fact in the
          Registration  Statement,  or any omission or alleged omission to state
          in the  Registration  Statement a material  fact required to be stated
          therein or necessary to make the statements therein not misleading.

          (a) The Issuer  agrees to  indemnify  and hold  harmless  each Selling
     Stockholder  and its  officers,  directors,  members  and their  respective
     successors and assigns (collectively,  the "Selling Stockholder Indemnified
     Parties")  from and  against  any third party  losses,  claims,  damages or

                                       10


     liabilities  to which such  Selling  Stockholder  Indemnified  Parties  may
     become  subject  (under the  Securities  Act or otherwise)  insofar as such
     losses,  claims,  damages or  liabilities  (or  actions or  proceedings  in
     respect  thereof)  arise out of, or are  based  upon (i) any  breach of the
     representations or warranties of the Issuer contained herein, or failure to
     comply with the covenants and  agreements of the Issuer  contained  herein,
     (ii) any untrue  statement of a material fact contained in the Registration
     Statement  as amended at the time of  effectiveness  or any  omission  of a
     material  fact  required  to be stated  therein  or  necessary  to make the
     statements  therein, in light of the circumstances in which they were made,
     not  misleading,  or  (iii)  any  failure  by the  Issuer  to  fulfill  any
     undertaking  included in the Registration  Statement as amended at the time
     of  effectiveness,  and the Issuer will reimburse such Selling  Stockholder
     Indemnified  Parties for any reasonable legal or other expenses  reasonably
     incurred  in  investigating,  defending  or  preparing  to defend  any such
     action,  proceeding or claim, provided,  however, that the Issuer shall not
     be liable in any such case to the extent that such loss,  claim,  damage or
     liability arises out of, or is based upon, an untrue statement made in such
     Registration  Statement or any omission of a material  fact  required to be
     stated therein or necessary to make the  statements  therein not misleading
     in reliance upon and in conformity  with written  information  furnished to
     the Issuer by or on behalf of such Selling Stockholder  Indemnified Parties
     specifically for use in preparation of the Registration Statement, a breach
     of any  representations  or  warranties  made by such  Selling  Stockholder
     herein, or the failure of such Selling  Stockholder  Indemnified Parties to
     comply with its covenants and agreements contained in this Agreement hereof
     or any  statement  or omission in any  Prospectus  that is corrected in any
     subsequent  Prospectus  that  was  delivered  to  the  Selling  Stockholder
     Indemnified  Party  prior to the  pertinent  sale or  sales by the  Selling
     Stockholder  Indemnified  Party.  The Issuer shall  reimburse  each Selling
     Stockholder Indemnified Party for the amounts provided for herein on demand
     as such expenses are incurred.

          (b) Each  Purchaser  agrees to indemnify  and hold harmless the Issuer
     (and each person,  if any,  who  controls the Issuer  within the meaning of
     Section 15 of the Securities  Act, each officer of the Issuer who signs the
     Registration  Statement  and each  director of the Issuer) from and against
     any third party losses,  claims, damages or liabilities to which the Issuer
     (or any such officer,  director or  controlling  person) may become subject
     (under the Securities Act or  otherwise),  insofar as such losses,  claims,
     damages or liabilities (or actions or proceedings in respect thereof) arise
     out of, or are  based  upon,  (i) any  breach  of the  representations  and
     warranties of such Purchaser  contained herein,  (ii) any failure to comply
     with the covenants and agreements of such Purchaser  contained  herein,  or
     (iii) any untrue statement of a material fact contained in the Registration
     Statement or any omission of a material fact required to be stated  therein
     or necessary to make the  statements  therein not misleading if such untrue
     statement  or omission  was made in reliance  upon and in  conformity  with
     written   information   furnished  by  or  on  behalf  of  such   Purchaser
     specifically for use in preparation of the Registration Statement, and such
     Purchaser  will  reimburse  the  Issuer  (or  such  officer,   director  or
     controlling  person),  as the case maybe, for any reasonable legal or other
     expenses  reasonably  incurred in investigating,  defending or preparing to
     defend any such action,  proceeding or claim; provided,  however, that such
     Purchaser's  obligation  to  indemnify  the  Issuer  or any  other  persons
     hereunder  shall be limited to the amount by which the net amount  received
     by such Purchaser from the sale of the Converted  Shares to which such loss
     relates  exceeds  the  amount  of any  damages  which  such  Purchaser  has
     otherwise  been  required  to pay by reason  of such  untrue  statement  or
     omission,  provided  further  that,  with  respect  to any  indemnification
     obligation   arising  under  clause  (iii)  of  this  paragraph  (b),  such
     obligation  shall be limited to the net amount  received by such  Purchaser
     from  the  sale  of the  Converted  Shares  included  in  the  Registration
     Statement in question.

          (c) Promptly after receipt by any indemnified  person of a notice of a
     claim or the beginning of any action in respect of which indemnity is to be
     sought against an  indemnifying  person  pursuant to this Section 8.3, such
     indemnified person shall notify the indemnifying  person in writing of such
     claim or of the commencement of such action,  but the omission to so notify

                                       11


     the indemnifying person will not relieve it from any liability which it may
     have to any indemnified person under this Section 8.3 (except to the extent
     that such  omission  materially  and  adversely  affects  the  indemnifying
     person's  ability to defend such  action) or from any  liability  otherwise
     than under this Section 8.3. Subject to the provisions  hereinafter stated,
     in case any such action shall be brought against an indemnified person, the
     indemnifying person shall be entitled to participate  therein,  and, to the
     extent that it shall elect by written notice  delivered to the  indemnified
     person promptly after receiving the aforesaid  notice from such indemnified
     person,  shall be  entitled  to assume the defense  thereof,  with  counsel
     reasonably  satisfactory to such indemnified person.  After notice from the
     indemnifying  person to such  indemnified  person of its election to assume
     the defense thereof,  such indemnifying  person shall not be liable to such
     indemnified  person for any legal  expenses  subsequently  incurred by such
     indemnified  person  in  connection  with the  defense  thereof,  provided,
     however,  that if there  exists or shall exist a conflict of interest  that
     would make it  inappropriate,  in the opinion of counsel to the indemnified
     person,  for the same counsel to represent both the indemnified  person and
     such  indemnifying  person  or any  affiliate  or  associate  thereof,  the
     indemnified  person  shall be  entitled  to retain  its own  counsel at the
     expense  of  such  indemnifying   person;   provided,   however,   that  no
     indemnifying  person shall be responsible for the fees and expenses of more
     than one separate counsel (together with appropriate local counsel) for all
     indemnified parties. In no event shall any indemnifying person be liable in
     respect  of any  amounts  paid  in  settlement  of any  action  unless  the
     indemnifying  person  shall  have  approved  the terms of such  settlement;
     provided  that  such  consent  shall  not  be  unreasonably   withheld.  No
     indemnifying  person  shall,  without  the  prior  written  consent  of the
     indemnified  person,  effect any  settlement  of any pending or  threatened
     proceeding in respect of which any indemnified person is or could have been
     a party and  indemnification  could  have  been  sought  hereunder  by such
     indemnified  person,  unless  such  settlement  includes  an  unconditional
     release of such  indemnified  person from all  liability on claims that are
     the subject matter of such proceeding.

          (d)  If  the  indemnification  provided  for in  this  Section  8.3 is
     unavailable to or insufficient to hold harmless an indemnified person under
     subsection  (a) or (b) above in respect of any losses,  claims,  damages or
     liabilities  (or actions or  proceedings  in respect  thereof)  referred to
     therein,  then each indemnifying person shall contribute to the amount paid
     or payable by such indemnified  person as a result of such losses,  claims,
     damages or liabilities  (or actions in respect  thereof) in such proportion
     as is  appropriate  to reflect the relative  fault of the Issuer on the one
     hand and the Purchaser(s) on the other in connection with the statements or
     omissions or other matters which resulted in such losses,  claims,  damages
     or  liabilities  (or  actions  in  respect  thereof),  as well as any other
     relevant equitable  considerations.  The relative fault shall be determined
     by reference  to, among other things,  in the case of an untrue  statement,
     whether the untrue statement relates to information  supplied by the Issuer
     on the one hand or the Purchaser(s) on the other and the parties'  relative
     intent,  knowledge,  access to  information  and  opportunity to correct or
     prevent such untrue statement.  The Issuer and the Purchasers agree that it
     would not be just and equitable if contribution pursuant to this subsection
     (d) were  determined by pro rata  allocation  (even if the Purchasers  were
     treated  as one  entity  for  such  purpose)  or by  any  other  method  of
     allocation  which does not take into account the  equitable  considerations
     referred to above in this  subsection (d). The amount paid or payable by an
     indemnified  person  as  a  result  of  the  losses,   claims,  damages  or
     liabilities  (or  actions in  respect  thereof)  referred  to above in this
     subsection  (d)  shall be  deemed to  include  any legal or other  expenses
     reasonably   incurred  by  such  indemnified   person  in  connection  with
     investigating  or defending any such action or claim.  Notwithstanding  the
     provisions  of this  subsection  (d), a Purchaser  shall not be required to
     contribute  any  amount  in excess  of the  amount by which the net  amount
     received by such Purchaser  from the sale of the Converted  Shares to which
     such loss relates  exceeds the amount of any damages  which such  Purchaser
     has otherwise been required to pay by reason of such untrue  statement.  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.  Each
     Purchaser's  obligations  in this  subsection  to  contribute  shall  be in

                                       12


     proportion  to its sale of Converted  Shares to which such loss relates and
     shall not be joint with any other Selling Stockholders.

          (e) The parties to this  Agreement  hereby  acknowledge  that they are
     sophisticated  business  persons who were represented by counsel during the
     negotiations regarding the provisions hereof including, without limitation,
     the provisions of this Section 8.3, and are fully  informed  regarding said
     provisions.  They further  acknowledge  that the provisions of this Section
     8.3 fairly  allocate  the risks in light of the  ability of the  parties to
     investigate  the Issuer and its  business in order to assure that  adequate
     disclosure  is  made  in the  Registration  Statement  as  required  by the
     Securities Act. The parties are advised that federal or state public policy
     as  interpreted by the courts in certain  jurisdictions  may be contrary to
     certain of the  provisions  of this  Section  8.3,  and the parties  hereto
     hereby  expressly  waive and relinquish any right or ability to assert such
     public  policy as a defense to a claim  under this  Section 8.3 and further
     agree not to attempt to assert any such defense.

          8.4  Termination  of  Conditions  and   Obligations.   The  conditions
     precedent  imposed  by  this  Agreement  upon  the  transferability  of the
     Converted Shares,  shall cease and terminate as to any particular Converted
     Shares when such Converted  Shares shall have been  effectively  registered
     under the  Securities  Act and sold or otherwise  disposed of in accordance
     with the  intended  method of  disposition  set  forth in the  Registration
     Statement  covering the  Converted  Shares or at such time as an opinion of
     counsel  reasonably  satisfactory to the Issuer shall have been rendered to
     the effect that such  conditions  are not necessary in order to comply with
     the Securities Act.

     9.  Notices.  All  notices,  requests,  consents  and other  communications
hereunder  shall be in writing,  shall be mailed (A) if within the United States

other party and its respective  officers,  directors,  employees and agents may,
and will, rely on the accuracy of the other party's  respective  representations
and  warranties  in this  Agreement  to  establish  compliance  with  applicable

          11.5  Severability.   The  invalidity  or   unenforceability   of  any
