                          REGISTRATION RIGHTS AGREEMENT

     REGISTRATION  RIGHTS AGREEMENT (this  "Agreement"),  dated as of August 26,
2002, among Avitar,  Inc., a Delaware  corporation  (the "Company"),  and Global
Capital Funding Group, L.P. (the "Fund").

     1. Introduction

          i. Securities Purchase Agreement.  The Company and the Fund have today
     executed  that  certain  Securities  Purchase  Agreement  (the  "Securities
     Purchase Agreement"), pursuant to which the Company has agreed, among other
     things,  to  issue a  $1,250,000.00  (U.S.)  principal  amount  of  Secured
     Promissory  Note of the Company (the "Note") to the Fund or its successors,
     assigns or transferees (collectively, the "Holders"). In addition, pursuant
     to the terms of the  Securities  Purchase  Agreement  and the  transactions
     contemplated  thereby,  the  Company  has issued to the Fund  Common  Stock
     Purchase  Warrants  exercisable for up to an aggregate of 600,000 shares of
     the Company's common stock,  $0.01 par value per share (the "Common Stock")
     (the  "Warrant  Shares").  The  number  of  Warrant  Shares is  subject  to
     adjustment  upon the  occurrence  of  stock  splits,  recapitalization  and
     similar events occurring after the date hereof.

          ii.  Definition of  Securities.  The Warrant  Shares are  collectively
     herein referred to as the "Securities."

          iii.  National  Market  Representation.  The  Company  represents  and
     warrants that the Company's Common Stock is currently  eligible for trading
     on the American  Stock  Exchange  ("Amex")  under the symbol "AVR." Certain
     capitalized  terms used in this  Agreement are defined in Section 3 hereof;
     references to sections shall be to sections of this Agreement.

     2. Registration under Securities Act, etc.

          2.1 Mandatory Registration.

               i. Registration of Registrable Securities.  The Company will file
          with the  Commission,  within 90 days  following  the date  hereof,  a
          Registration  Statement on Form S-3 (the "Registration  Statement") to
          register the resale of the Common Shares issuable upon the exercise of
          the  Warrants.  The  Company  will use its best  efforts  to cause the
          Registration  Statement to become effective within (i) 120 days of the
          Date hereof, (ii) ten (10) days following the receipt of a "No Review"
          or similar letter from the Commission or (iii) the first day following
          the day the Commission determines the Registration  Statement eligible
          to be declared effective (the "Required  Effectiveness Date"). Nothing
          contained  herein  shall be deemed to limit the number of  Registrable
          Securities  to be registered  by the Company  hereunder.  As a result,
          should the Registration  Statement not relate to the maximum number of
          Registrable  Securities acquired by (or potentially acquirable by) the
          holders thereof upon conversion of the Note, or exercise of the Common
          Stock  Purchase  Warrants  described  in Section 1 above,  the Company
          shall be required to promptly file a separate  registration  statement
          (utilizing  Rule  462  promulgated   under  the  Exchange  Act,  where
          applicable) relating to such Registrable  Securities which then remain
          unregistered.  The  provisions of this  Agreement  shall relate to any
          such separate registration statement as if it were an amendment to the
          Registration Statement.

               ii. Registration  Statement Formii.  Registration Statement Form.
          Registrations  under  this  Section  2.1  shall be on Form S-3 or such
          other appropriate  registration form of the Commission as shall permit
          the disposition of such Registrable  Securities in accordance with the
          intended  method or  methods  of  disposition  specified  by the Fund;
          provided,  however,  such  intended  method  of  deposition  shall not
          include an underwritten offering of the Registrable Securities.

               iii. Expenses.  The Company will pay all Registration Expenses in
          connection with any registration required by this Section 2.1.

               iv. Effective Registration Statementiv.  A registration requested
          pursuant to this Section 2.1 shall not be deemed to have been effected
          (i) unless a registration  statement  with respect  thereto has become
          effective,   provided  that  a  registration  which  does  not  become
          effective  after  the  Company  filed a  registration  statement  with
          respect  thereto  solely by reason of the  refusal  to  proceed of any
          holder of  Registrable  Securities  (other  than a refusal  to proceed
          based upon the  advice of  counsel  in the form of a letter  signed by
          such  counsel and  provided to the  Company  relating to a  disclosure
          matter unrelated to such holder) shall be deemed to have been effected
          by the Company unless the holders of the Registrable  Securities shall
          have elected to pay all Registration  Expenses in connection with such
          registration,   (ii)  if,   after  it  has  become   effective,   such
          registration  becomes  subject to any stop order,  injunction or other
          order  or  extraordinary   requirement  of  the  Commission  or  other
          governmental  agency or court for any reason or (iii) if, after it has
          become effective,  such  registration  ceases to be effective for more
          than an aggregate of ninety (90) days.

               v. Plan of  Distributionv.  The  Company  hereby  agrees that the
          Registration  Statement shall include a plan of  distribution  section
          reasonably  acceptable to the Fund;  provided,  however,  such plan of
          distribution  section  shall be  modified  by the Company so as to not
          provide for the disposition of the Registrable Securities on the basis
          of an underwritten offering.

          2.2 Incidental Registration.


               i. Right to Include Registrable Securities. If any time after the
          date hereof but before the third  anniversary of the date hereof,  the
          Company   proposes  to  register  any  of  its  securities  under  the
          Securities  Act (other than by a  registration  in connection  with an
          acquisition  in a  manner  which  would  not  permit  registration  of
          Registrable  Securities  for sale to the  public,  on Form S-8, or any
          successor form thereto, on Form S-4, or any successor form thereto and
          other than pursuant to Section 2.1), on an underwritten  basis (either
          best-efforts  or  firm-commitment),  then,  the Company will each such
          time give prompt  written notice to all Holders of its intention to do
          so and of such  Holders'  rights  under  this  Section  2.2.  Upon the
          written  request of any such Holder made within twenty (20) days after
          the  receipt of any such  notice  (which  request  shall  specify  the
          Registrable  Securities  intended  to be disposed of by such Holder an
          and the intended  method of  disposition  thereof),  the Company will,
          subject to the terms of this Agreement,  effect the registration under
          the  Securities  Act  of the  Registrable  Securities,  to the  extent
          requisite to permit the  disposition  (in accordance with the intended
          methods thereof as aforesaid) of such Registrable  Securities so to be
          registered,  by  inclusion  of  such  Registrable  Securities  in  the
          registration  statement which covers the securities  which the Company
          proposes  to  register,  provided  that if, at any time after  written
          notice of its  intention to register any  securities  and prior to the
          effective date of the registration  statement filed in connection with
          such  registration,  the Company shall determine for any reason either
          not to  register  or to delay  registration  of such  securities,  the
          Company  may,  at  its   election,   give   written   notice  of  such
          determination  to each  Holder  and,  thereupon,  (i) in the case of a
          determination not to register, shall be relieved of this obligation to
          register  any   Registrable   Securities  in   connection   with  such
          registration  (but  not from its  obligation  to pay the  Registration
          Expenses in connection therewith),  without prejudice, however, to the
          rights of any holder or holders of Registrable  Securities entitled to
          do so to request that such  registration be effected as a registration
          under  Section 2.1, and (ii) in the case of a  determination  to delay
          registering,  shall be permitted to delay  registering any Registrable
          Securities, for the same period as the delay in registering such other
          securities.  No  registration  effected  under this  Section 2.2 shall
          relieve the Company of its obligation to effect any registration  upon
          request under Section 2.1, nor shall any such  registration  hereunder
          be deemed to have been  effected  pursuant to Section 2.1. The Company
          will  pay  all   Registration   Expenses  in   connection   with  each
          registration  of  Registrable  Securities  requested  pursuant to this
          Section  2.2.  The  right  provided  the  Holders  of the  Registrable
          Securities pursuant to this Section shall be exercisable at their sole
          discretion  and will in no way limit any of the Company's  obligations
          to pay the Securities according to their terms.

               ii.  Priority  in  Incidental  Registrations.   If  the  managing
          underwriter of the underwritten  offering contemplated by this Section
          2.2 shall inform the Company and holders of the Registrable Securities
          requesting  such  registration by letter of its belief that the number
          of securities  requested to be included in such  registration  exceeds
          the number which can be sold in such  offering,  then the Company will
          include in such  registration,  to the extent of the number  which the
          Company  is so  advised  can be  sold  in  such  offering,  (i)  first
          securities proposed by the Company to be sold for its own account, and
          (iii) second  Registrable  Securities  and securities of other selling
          security  holders  requested to be included in such  registration  pro
          rata on the  basis of the  number  of  shares  of such  securities  so
          proposed  to be  sold  and  so  requested  to be  included;  provided,
          however, the holders of Registrable  Securities shall have priority to
          all shares  sought to be  included by officers  and  directors  of the
          Company  as  well  as  holders  of ten  percent  (10%)  or more of the
          Company's Common Stock.

          2.3 Registration  Procedures.  If and whenever the Company is required
     to  effect  the  registration  of  any  Registrable  Securities  under  the
     Securities  Act as provided in Section 2.1 and,  as  applicable,  2.2,  the
     Company shall, as expeditiously as possible:

               i.  prepare  and  file  with  the  Commission  the   Registration
          Statement  to  effect  such   registration   (including  such  audited
          financial  statements as may be required by the  Securities Act or the
          rules and regulations  promulgated  thereunder) and thereafter use its
          best  efforts  to cause such  registration  statement  to be  declared
          effective by the Commission, as soon as practicable,  but in any event
          no later  than the  Required  Effectiveness  Date  (with  respect to a
          registration pursuant to Section 2.1); provided,  however, that before
          filing such  registration  statement or any  amendments  thereto,  the
          Company  will  furnish  to the  counsel  selected  by the  holders  of
          Registrable  Securities which are to be included in such registration,
          copies of all such documents proposed to be filed;

               ii.  with  respect  to any  Registration  Statement  pursuant  to
          Section 2.1,  prepare and file with the Commission such amendments and
          supplements to such registration  statement and the prospectus used in
          connection  therewith as may be  necessary  to keep such  registration
          statement   effective  and  to  comply  with  the  provisions  of  the
          Securities  Act with  respect to the  disposition  of all  Registrable
          Securities covered by such registration  statement,  until the earlier
          to occur of six (6) years after the date of this  Agreement(subject to
          the right of the Company to suspend the effectiveness  thereof for not
          more than 10  consecutive  days or an aggregate of 30 days in such six
          (6) years period) or such time as all of the securities  which are the
          subject  of  such  registration  statement  cease  to  be  Registrable
          Securities (such period, in each case, the  "Registration  Maintenance
          Period");

               iii. furnish to each seller of Registrable  Securities covered by
          such  registration  statement such number of conformed  copies of such
          registration  statement  and of each  such  amendment  and  supplement
          thereto (in each case including all  exhibits),  such number of copies
          of the prospectus contained in such registration  statement (including
          each preliminary  prospectus and any summary prospectus) and any other
          prospectus   filed  under  Rule  424  under  the  Securities  Act,  in
          conformity with the requirements of the Securities Act, and such other
          documents,  as such seller and  underwriter,  if any,  may  reasonably
          request in order to facilitate the public sale or other disposition of
          the Registrable Securities owned by such seller;

               iv.  use its  reasonable  efforts  to  register  or  qualify  all
          Registrable   Securities   and  other   securities   covered  by  such
          registration  statement  under such other  securities laws or blue sky
          laws as any seller  thereof  shall  reasonably  request,  to keep such
          registrations  or  qualifications  in  effect  for  so  long  as  such
          registration  statement  remains in effect,  and take any other action
          which may be reasonably  necessary to enable such seller to consummate
          the disposition in such  jurisdictions of the securities owned by such
          seller,  except  that the  Company  shall not for any such  purpose be
          required to qualify generally to do business as a foreign  corporation
          in any  jurisdiction  wherein it would not but for the requirements of
          this subdivision (iv) be obligated to be so qualified or to consent to
          general service of process in any such jurisdiction;


               v.  use its best  efforts  to cause  all  Registrable  Securities
          covered  by  such  registration  statement  to be  registered  with or
          approved by such other governmental  agencies or authorities as may be
          necessary to enable the seller or sellers  thereof to  consummate  the
          disposition of such Registrable Securities;

               vi.  furnish to each seller of  Registrable  Securities  a signed
          counterpart,  addressed to such seller, and the underwriters,  if any,
          of:

                    (A) an  opinion  of  counsel  for  the  Company,  dated  the
               effective  date  of  such  registration  statement  (or,  if such
               registration includes an underwritten public offering, an opinion
               dated   the  date  of  the   closing   under   the   underwriting
               agreement),reasonably  satisfactory in form and substance to such
               seller)   including   that  the  prospectus  and  any  prospectus
               supplement forming a part of the Registration  Statement does not
               contain  an  untrue  statement  of a  material  fact  or  omits 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, and

                    (B) a "comfort"  letter (or, in the case of any Person which
               does not satisfy the conditions for receipt of a "comfort" letter
               specified in Statement on Auditing  Standards  No. 72, an "agreed
               upon  procedures"  letter),  dated  the  effective  date  of such
               registration  statement  (and, if such  registration  includes an
               underwritten  public  offering,  a letter of like kind  dated the
               date of the closing under the underwriting agreement),  signed by
               the  independent   public  accountants  who  have  certified  the
               Company's  financial  statement  included  in  such  registration
               statement,  covering  substantially the same matters with respect
               to such  registration  statement  (and  the  prospectus  included
               therein)  and,  in the  case  of the  accountants'  letter,  with
               respect  to  events  subsequent  to the  date of  such  financial
               statements,  as are  customarily  covered in opinions of issuer's
               counsel and in accountants' letters delivered to the underwriters
               in underwritten public offerings of securities (with, in the case
               of an "agreed upon  procedures"  letter,  such  modifications  or
               deletions  as  may  be  required  under   Statement  on  Auditing
               Standards  No. 35) and, in the case of the  accountants'  letter,
               such  other  financial  matters,  and,  in the case of the  legal
               opinion,  such  other  legal  matters,  as  such  seller  (or the
               underwriters, if any) may reasonably request;

               vii. notify the Sellers'  Representative and its counsel promptly
          and  confirm  such  advice in writing  promptly  after the Company has
          knowledge thereof:

                    (A) when the Registration  Statement,  the prospectus or any
               prospectus supplement related thereto or post-effective amendment
               to the Registration  Statement has been filed,  and, with respect
               to the  Registration  Statement or any  post-effective  amendment
               thereto, when the same has become effective;

                    (B) of any  request  by the  Commission  for  amendments  or
               supplements  to the  Registration  Statement or the prospectus or
               for additional information;

                    (C) of the  issuance  by the  Commission  of any stop  order
               suspending the effectiveness of the Registration Statement or the
               initiation of any proceedings by any Person for that purpose; and

                    (D) of the receipt by the Company of any  notification  with
               respect to the suspension of the qualification of any Registrable
               Securities  for sale under the securities or blue sky laws of any
               jurisdiction  or the  initiation or threat of any  proceeding for
               such purpose;

               viii.  notify each seller of  Registrable  Securities  covered by
          such registration  statement,  at any time when a prospectus  relating
          thereto is required to be delivered  under the  Securities  Act,  upon
          discovery  that,  or upon the  happening  of any  event as a result of
          which, the prospectus included in such registration statement, as then
          in effect, includes an untrue statement of a material fact or omits to
          state any material facts required to be stated therein or necessary to
          make  the  statements  therein  not  misleading  in the  light  of the
          circumstances  then  existing,  and at the  request of any such seller
          promptly  prepare and furnish to such  seller a  reasonable  number of
          copies of a supplement to or an amendment of such prospectus as may be
          necessary so that, as thereafter  delivered to the  purchasers of such
          securities, such prospectus shall not include 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 not misleading in
          the light of the circumstances then existing;

               ix. use its best  efforts to obtain the  withdrawal  of any order
          suspending  the  effectiveness  of the  Registration  Statement at the
          earliest possible moment;

               x.  otherwise use its best efforts to comply with all  applicable
          rules and  regulations  of the  Commission,  and make available to its
          security  holders,  as soon as  reasonably  practicable,  an  earnings
          statement  covering the period of at least twelve months, but not more
          than eighteen  months,  beginning  with the first full calendar  month
          after  the  effective  date  of  such  registration  statement,  which
          earnings  statement  shall satisfy the  provisions of Section 11(a) of
          the Securities Act and Rule 158 thereunder;

               xi. enter into such agreements and take such other actions as the
          Sellers'  Representative  shall reasonably  request in writing (at the
          expense of the requesting or benefiting  sellers) in order to expedite
          or facilitate the disposition of such Registrable Securities; and

               xii.  use its best  efforts  to list all  Registrable  Securities
          covered by such registration  statement on any securities  exchange on
          which any of the Registrable Securities are then listed.

     The Company may require each seller of  Registrable  Securities as to which
any  registration  is being  effected to furnish the  Company  such  information
regarding such seller and the distribution of such securities as the Company may
from time to time reasonably request in writing.

     The Company will not file any  registration  statement  pursuant to Section
2.1, or amendment thereto or any prospectus or any supplement thereto (including
such  documents  incorporated  by  reference  and proposed to be filed after the
initial   filing  of  the   Registration   Statement)   to  which  the  Sellers'
Representative shall reasonably object,  provided that the Company may file such
documents in a form required by law or upon the advice of its counsel.


     The  Company   represents  and  warrants  to  each  holder  of  Registrable
Securities   that  it  has  obtained  all   necessary   waivers,   consents  and
authorizations   necessary  to  execute  this   Agreement  and   consummate  the
transactions  contemplated  hereby  other  than such  waivers,  consents  and/or
authorizations specifically contemplated by the Securities Purchase Agreement.

     The Fund agrees  that,  upon  receipt of any notice from the Company of the
occurrence  of any event of the kind  described  in  subdivision  (viii) of this
Section 2.3,  the Fund will  forthwith  discontinue  the Fund's  disposition  of
Registrable  Securities pursuant to the Registration  Statement relating to such
Registrable   Securities   until  the  Fund's  receipt  of  the  copies  of  the
supplemented or amended  prospectus  contemplated by subdivision  (viii) of this
Section 2.3 and, if so directed by the Company,  will deliver to the Company (at
the Company's expense) all copies, other than permanent file copies, then in the
Fund's  possession of the  prospectus  relating to such  Registrable  Securities
current at the time of receipt of such notice.

          2.4 Underwritten Offerings.

               i. Incidental  Underwritten Offerings. If the Company at any time
          proposes to register any of its securities under the Securities Act as
          contemplated  by Section 2.2 and such securities are to be distributed
          by or through one or more underwriters, the Company will, if requested
          by any holder of Registrable Securities as provided in Section 2.2 and
          subject  to the  provisions  of  Section  2.2(i),  use its  reasonable
          efforts  to  arrange  for  such   underwriters   to  include  all  the
          Registrable Securities to be offered and sold by such holder among the
          securities to be distributed by such underwriters.

               ii.  Holdback  Agreements.   Subject  to  such  other  reasonable
          requirements  as may be imposed by the  underwriter  as a condition of
          inclusion  of a  Fund's  Registrable  Securities  in the  registration
          statement,  each Fund agrees by acquisition of Registrable Securities,
          if so  required by the  managing  underwriter,  not to sell,  make any
          short sale of, loan,  grant any option for the purchase of, effect any
          public sale or distribution of or otherwise dispose of, except as part
          of  such  underwritten  registration,  any  equity  securities  of the
          Company,  during  such  reasonable  period  of time  requested  by the
          underwriter;  provided  however,  such period shall not exceed the 120
          day  period  commencing  30 days  prior  to the  commencement  of such
          underwritten  offering and ending 90 days  following the completion of
          such underwritten offering.


               iii.  Participation  in  Underwritten  Offerings.  No  holder  of
          Registrable  Securities may participate in any  underwritten  offering
          under  Section 2.2 unless such holder of  Registrable  Securities  (i)
          agrees to sell such Person's  securities on the basis  provided in any
          underwriting   arrangements   approved,   subject  to  the  terms  and
          conditions  hereof,  by  the  holders  of a  majority  of  Registrable
          Securities  to be  included  in such  underwritten  offering  and (ii)
          completes and executes all questionnaires,  indemnities,  underwriting
          agreements  and  other  documents  (other  than  powers  of  attorney)
          required   under   the  terms  of  such   underwriting   arrangements.
          Notwithstanding  the foregoing,  no  underwriting  agreement (or other
          agreement in connection  with such offering)  shall require any holder
          of Registrable  Securities to make an representations or warranties to
          or  agreements  with  the  Company  or  the  underwriters  other  than
          representations  and  warranties  contained in a writing  furnished by
          such holder expressly for use in the related registration statement or
          representations,  warranties or agreements regarding such holder, such
          holder's  Registrable  Securities and such holder's intended method of
          distribution and any other representation required by law.

          2.5  Preparation;  Reasonable  Investigation.  In connection  with the
     preparation and filing of each registration  statement under the Securities
     Act  pursuant  to this  Agreement,  the  Company  will give the  holders of
     Registrable  Securities registered under such registration  statement,  and
     their respective counsel and accountants, the opportunity to participate in
     the preparation of such registration  statement,  each prospectus  included
     therein  or  filed  with the  Commission,  and each  amendment  thereof  or
     supplement thereto, and will give each of them such access to its books and
     records and such  opportunities to discuss the business of the Company with
     its officers and the independent  public accountants who have certified its
     financial  statements as shall be necessary,  in the reasonable  opinion of
     such  holders'  and such  underwriters'  respective  counsel,  to conduct a
     reasonable investigation within the meaning of the Securities Act.

          2.6   Registration   Default  Fee.  If  the   Registration   Statement
     contemplated  in Section 2.1 is (x) not declared  effective by the Required
     Effectiveness  Date or (y) such  effectiveness  is not  maintained  for the
     Registration Maintenance Period, then the Company shall pay to the Fund the
     applicable Default Fee specified in Section 10.4 of the Securities Purchase
     Agreement.

          2.7 Indemnification

               i.   Indemnification  by  the  Company.   In  the  event  of  any
          registration  of any  securities of the Company  under the  Securities
          Act, the Company  will,  and hereby does agree to  indemnify  and hold
          harmless  the  holder of any  Registrable  Securities  covered by such
          registration statement,  its directors and officers, each other Person
          who  participates  as an  underwriter  in the offering or sale of such
          securities and each other Person,  if any, who controls such holder or
          any such underwriter  within the meaning of the Securities Act against
          any losses, claims, damages or liabilities, joint or several, to which
          such  holder  or any  such  director  or  officer  or  underwriter  or
          controlling  person may become  subject  under the  Securities  Act or
          otherwise,  insofar as such losses, claims, damages or liabilities (or
          actions or proceedings,  whether  commenced or threatened,  in respect
          thereof)  arise  out of or are  based  upon any  untrue  statement  or
          alleged  untrue  statement  of  any  material  fact  contained  in any
          registration  statement  under which such  securities  were registered
          under the Securities Act, any preliminary prospectus, final prospectus
          or  summary  prospectus   contained  therein,   or  any  amendment  or
          supplement  thereto,  or any  omission  or alleged  omission  to state
          therein a material fact required to be stated  therein or necessary to
          make the  statements  therein not  misleading,  and the  Company  will
          reimburse such holder and each such director, officer, underwriter and
          controlling  person  for any  legal or any other  expenses  reasonably
          incurred by them in  connection  with  investigating  or defending any
          such loss, claim, liability,  action or proceeding,  provided that the
          Company  shall not be liable in any such case to the  extent  that any
          such loss,  claim,  damage,  liability,  (or action or  proceeding  in
          respect  thereof) or expense  arises out of or is based upon an untrue
          statement or alleged untrue  statement or omission or alleged omission
          made in such registration statement,  any such preliminary prospectus,
          final  prospectus,  summary  prospectus,  amendment or  supplement  in
          reliance upon and in conformity with written information  furnished to
          the Company by such holder or  underwriter  stating that it is for use
          in the  preparation  thereof  and,  provided  further that the Company
          shall not be liable to any Person who  participates  as an underwriter
          in the  offering  or sale of  Registrable  Securities  or to any other
          Person,  if any, who controls such  underwriter  within the meaning of
          the Securities Act, in any such case to the extent that any such loss,
          claim, damage,  liability (or action or proceeding in respect thereof)
          or expense arises out of such Person's  failure to send or give a copy
          of the  final  prospectus,  as the  same may be then  supplemented  or
          amended,  within the time required by the Securities Act to the Person
          asserting  the  existence  of an untrue  statement  or alleged  untrue
          statement  or omission or alleged  omission at or prior to the written
          confirmation  of the sale of Registrable  Securities to such Person if
          such  statement or omission was corrected in such final  prospectus or
          an amendment or supplement  thereto.  Such  indemnity  shall remain in
          full force and effect  regardless of any  investigation  made by or on
          behalf of such holder or any such  director,  officer,  underwriter or
          controlling  person and shall survive the transfer of such  securities
          by such holder.

               ii. Indemnification by the Sellers. The Company may require, as a
          condition to including any Registrable  Securities in any registration
          statement  filed  pursuant to this  Agreement,  the Company shall have
          received an undertaking satisfactory to it from the prospective seller
          of such Registrable Securities, to indemnify and hold harmless (in the
          same manner and to the same extent as set forth in subdivision  (i) of
          this  Section  2.7) the Company,  each  director of the Company,  each
          officer of the Company and each other Person, if any, who controls the
          Company within the meaning of the Securities  Act, with respect to any
          statement or alleged statement in or omission or alleged omission from
          such  registration  statement,   any  preliminary  prospectus,   final
          prospectus or summary prospectus  contained therein,  or any amendment
          or  supplement  thereto,  if such  statement  or alleged  statement or
          omission  or  alleged  omission  was  made  in  reliance  upon  and in
          conformity with written  information  furnished to the Company through
          an instrument duly executed by such seller  specifically  stating that
          it is for  use in the  preparation  of  such  registration  statement,
          preliminary   prospectus,   final  prospectus,   summary   prospectus,
          amendment or supplement. Any such indemnity shall remain in full force
          and effect,  regardless of any  investigation  made by or on behalf of
          the Company or any such director,  officer or  controlling  person and
          shall survive the transfer of such securities by such seller.


               iii.  Notices  of  Claims,  etc.  Promptly  after  receipt  by an
          indemnified  party of  notice  of the  commencement  of any  action or
          proceeding involving a claim referred to in the preceding subdivisions
          of this  Section  2.7,  such  indemnified  party  will,  if a claim in
          respect  thereof is to be made  against an  indemnifying  party,  give
          written  notice to the  latter  of the  commencement  of such  action,
          provided that the failure of any  indemnified  party to give notice as
          provided  herein  shall  not  relieve  the  indemnifying  party of its
          obligations  under the  preceding  subdivisions  of this  Section 2.7,
          except  to  the  extent  that  the  indemnifying   party  is  actually
          prejudiced by such failure to give notice.  In case any such action is
          brought  against  an  indemnified  party,  unless in such  indemnified
          party's  reasonable  judgment  a conflict  of  interest  between  such
          indemnified  and  indemnifying  parties  may exist in  respect of such
          claim, the indemnifying  party shall be entitled to participate in and
          to assume the defense  thereof,  jointly  with any other  indemnifying
          party similarly  notified,  to the extent that the indemnifying  party
          may wish, with counsel  reasonably  satisfactory  to such  indemnified
          party,  and  after  notice  from  the   indemnifying   party  to  such
          indemnified  party of its  election so to assume the defense  thereof,
          the indemnifying  party shall not be liable to such indemnified  party
          for any legal or other expenses subsequently incurred by the latter in
          connection  with the defense  thereof other than  reasonable  costs of
          investigation. No indemnifying party shall, without the consent of the
          indemnified party,  consent to entry of any judgment or enter into any
          settlement   of  any  such  action   which  does  not  include  as  an
          unconditional  term thereof the giving by the claimant or plaintiff to
          such indemnified party of a release from all liability,  or a covenant
          not to sue,  in respect to such claim or  litigation.  No  indemnified
          party  shall  consent  to entry  of any  judgment  or  enter  into any
          settlement of any such action the defense of which has been assumed by
          an indemnifying party without the consent of such indemnifying party.

               iv.  Other  Indemnification.   Indemnification  similar  to  that
          specified  in the  preceding  subdivisions  of this  Section 2.7 (with
          appropriate  modifications)  shall be given  by the  Company  and each
          seller  of  Registrable  Securities  (but  only  if and to the  extent
          required  pursuant  to the  terms  of  2.7(ii))  with  respect  to any
          required  registration or other  qualification of securities under any
          Federal  or state law or  regulation  of any  governmental  authority,
          other than the Securities Act.

               v. Indemnification Payments. The indemnification required by this
          Section 2.7 shall be made by periodic  payments of the amount  thereof
          during the course of the  investigation or defense,  as and when bills
          are received or expense, loss, damage or liability is incurred.


               vi.  Contribution.  If the  indemnification  provided  for in the
          preceding  subdivision  of  this  Section  2.7  is  unavailable  to an
          indemnified party in respect of any expense,  loss,  claim,  damage or
          liability referred to therein,  then each indemnifying  party, in lieu
          of indemnifying such indemnified party, shall contribute to the amount
          paid or payable by such indemnified party as a result of such expense,
          loss,  claim,  damage  or  liability  (i)  in  such  proportion  as is
          appropriate to reflect the relative  benefits  received by the Company
          on the one hand and the holder or underwriter,  as the case may be, on
          the other from the distribution of the Registrable  Securities or (ii)
          if the  allocation  provided by clause (i) above is not  permitted  by
          applicable  law, in such  proportion as is  appropriate to reflect not
          only the  relative  benefits  referred to in clause (i) above but also
          the relative fault of the Company on the one hand and of the holder or
          underwriter,  as the case may be, on the other in connection  with the
          statements or omissions which resulted in such expense,  loss,  damage
          or liability, as well as any other relevant equitable  considerations.
          The relative  benefits received by the Company on the one hand and the
          holder or underwriter,  as the case may be, on the other in connection
          with the distribution of the Registrable Securities shall be deemed to
          be in the same  proportion  as the total net proceeds  received by the
          Company from the initial  sale of the  Registrable  Securities  by the
          Company to the  purchasers  bear to the gain, if any,  realized by all
          selling  holders  participating  in such offering or the  underwriting
          discounts and commissions received by the underwriter, as the case may
          be.  The  relative  fault  of the  Company  on the one hand and of the
          holder  or  underwriter,  as the case may be,  on the  other  shall be
          determined by reference to, among other things,  whether the untrue or
          alleged  untrue  statement  of a material  fact or omission to state a
          material fact relates to information  supplied by the Company,  by the
          holder  or by  the  underwriter  and  the  parties'  relative  intent,
          knowledge,  access to  information  supplied  by the  Company,  by the
          holder  or by  the  underwriter  and  the  parties'  relative  intent,
          knowledge, access to information and opportunity to correct or prevent
          such statement or omission,  provided that the foregoing  contribution
          agreement shall not inure to the benefit of any  indemnified  party if
          indemnification  would be  unavailable  to such  indemnified  party by
          reason  of  the   provisions   contained  in  the  first  sentence  of
          subdivision  (i) of  this  Section  2.7,  and in no  event  shall  the
          obligation  of  any  indemnifying   party  to  contribute  under  this
          subdivision (vi) exceed the amount that such indemnifying  party would
          have  been  obligated  to  pay  by  way  of   indemnification  if  the
          indemnification  provided for under  subdivisions (ii) of this Section
          2.7 had been available under the circumstances.

     The Company and the holders of Registrable  Securities  agree that it would
not be just and equitable if contribution pursuant to this subdivision (vi) were
determined by pro rata allocation (even if the holders and any underwriters were
treated as one entity for such  purpose)  or by any other  method of  allocation
that does not take account of the  equitable  considerations  referred to in the
immediately  preceding  paragraph.  The amount paid or payable by an indemnified
party as a result of the losses,  claims, damages and liabilities referred to in
the immediately  preceding paragraph shall be deemed to include,  subject to the
limitations set forth in the preceding  sentence and  subdivision  (iii) of this
Section 2.7, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.

     Notwithstanding  the  provisions  of this  subdivision  (vi),  no holder of
Registrable Securities or underwriter shall be required to contribute any amount
in excess of the  amount  by which (i) in the case of any such  holder,  the net
proceeds received by such holder from the sale of Registrable Securities or (ii)
in the  case of an  underwriter,  the  total  price  at  which  the  Registrable
Securities  purchased  by it and  distributed  to the public were offered to the
