                          REGISTRATION RIGHTS AGREEMENT

     REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of May 25, 2004,
among Avitar, Inc., a Delaware  corporation (the "Company"),  and Global Capital
Funding Group, L.P. (the "Fund").

     1. Introduction.

          i. Exchange  Agreement.  The Company and the Fund have today  executed
     that certain  Exchange  Agreement (the "Exchange  Agreement"),  pursuant to
     which the Company has agreed,  among other things, to exchange 1,316 shares
     of its Series A Preferred  Stock,  4% Cumulative  Dividend (the  "Preferred
     Stock") for the $1,250,000.00 (U.S.) principal amount of Secured Promissory
     Preferred  Stock of the Company (the "Note")  currently held by the Fund or
     its successors,  assigns or transferees (collectively,  the "Holders"). The
     Company has previously  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 Common Stock issued upon conversion
     of the  Preferred  Stock and 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 30 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) 90 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
     Preferred  Stock,  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 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   Statement.  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   Distribution.   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 at 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 Exchange 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 Exchange 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
public exceeds,  in any such case, the amount of any damages that such holder or
underwriter  has  otherwise  been  required  to pay by reason of such  untrue or
allege   untrue   statement  or  omission.   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.
