EXHIBIT 10.1



                            STOCK PURCHASE AGREEMENT


         This Agreement  ("Agreement") is entered into this 14th day of January,
1998, by and between Biomar International, Inc., a Delaware corporation with its
principal   offices  in  Chapel  Hill,  North  Carolina  (the  "Purchaser")  and
Paracelsian, Inc., a Delaware corporation with its principal offices in New York
(the "Corporation").

WHEREAS, the Purchaser desires to purchase from the Corporation  3,571,429 newly
issued shares of the common stock of the Corporation (the "Shares") on the terms
and subject to the conditions set forth herein; and

WHEREAS,  the  Board  of  Directors  of the  Corporation,  due to the  financial
condition of the Corporation, desires to sell to the Purchaser the Shares on the
terms and subject to the conditions set forth herein.

NOW THEREFORE, IT IS AGREED AS FOLLOWS:

SECTION 1.   PURCHASE OF SHARES.

1.1      PURCHASE  OF  SHARES.  Subject  to the terms and  conditions  set forth
herein, on or before January 15, 1998 (the "Purchase Date"),  the Purchaser will
purchase 3,571,429 Shares and the Corporation will issue the Shares purchased by
the Purchaser,  said Shares constituting  approximately  thirty percent (30%) of
all of the then issued and  outstanding  capital stock of the  Corporation as of
the Purchase  Date. On the Closing Date (as  hereinafter  defined) the Purchaser
will also receive  warrants to purchase up to an  additional  $520,000 in common
stock, in increments of at least $100,000,  at a per share price equal to $0.175
(the "Warrants"). The Warrants are in the form attached as Exhibit 1.1A and will
be  exercisable at any time prior to their  expiration  which will occur 90 days
from the date the Shares and Warrants are  registered  with the  Securities  and
Exchange  Commission ("SEC") as provided under the Registration Rights Agreement
in the form  attached as Exhibit  1.1B.  To the extent that the  exercise of the
Warrants  will  require an  increase  in the number of  authorized  shares,  the
Corporation  will use its best  efforts  to obtain  shareholder  approval  of an
increase in the  authorized  shares  sufficient to  accommodate  issuance of the
shares under the Warrant.

1.2      PURCHASE  PRICE.  The Purchaser will pay to the  Corporation the sum of
five hundred thousand  dollars  ($500,000) for the Shares (referred herein to as
the "Purchase Price").

1.3      PAYMENT OF PURCHASE PRICE.  The Purchase Price will be paid as follows:
(i) the Purchaser will pay to the Corporation the sum of fifty thousand  dollars
($50,000) on the Closing Date;  and (ii) the  Purchaser  will deliver the sum of
four hundred and fifty thousand dollars ($450,000) on the Purchase Date.

SECTION 2.   REPRESENTATIONS  AND  WARRANTIES  OF  CORPORATION.  As  a  material
inducement  to the  Purchaser  to enter into this  Agreement  and  purchase  the
Shares,  the  Corporation  represents  and  warrants  that  to the  best  of the
knowledge of the Corporation:

2.1      ORGANIZATION AND CORPORATE POWER. The Corporation is a corporation duly
incorporated  and validly  existing  under the laws of the State of Delaware and
the  Corporation is qualified to do business in every  jurisdiction in which its
ownership  of  property or conduct of  business  requires it to qualify,  except
where any failure does not have a material  adverse  effect on the  Corporation.
The Corporation has all requisite corporate power and authority and all material
licenses,   permits,  and  authorizations  necessary  to  own  and  operate  its
properties  and to carry on its  business  as now  conducted,  except  where any
failure does not have a material adverse effect on the  Corporation.  The copies

                                       7
<PAGE>


of the Corporation's articles of incorporation and bylaws have been furnished to
the Purchaser and such copies  reflect all  amendments  made thereto at any time
prior to the date of this Agreement and such copies are correct and complete.

2.2      CAPITAL STOCK AND RELATED MATTERS.  (a) The authorized capital stock of
the Corporation consists of twenty million (20,000,000) Shares,  twelve million,
four thousand,  eight hundred and sixty seven  (12,004,867)  of which are issued
and  outstanding  and are  owned,  of  record,  as  shown  on the  books  of the
Corporation  on December 31, 1997 and no other shares,  common or otherwise,  of
the  Corporation are issued and  outstanding.  Except as listed on Schedule 2.2,
the  Corporation  does not have  outstanding  and has not  agreed,  orally or in
writing,  to issue any shares or securities  convertible or exchangeable for any
shares, nor does it have outstanding nor has it agreed, orally or in writing, to
issue any  options or rights to purchase or  otherwise  acquire its shares.  The
Corporation  is not  subject to any  obligation  (contingent  or  otherwise)  to
repurchase or otherwise acquire or retire any of its shares. Except as listed on
Schedule 2.2, the Corporation has not violated any applicable securities laws or
regulations in connection  with the offer or sale of its  securities  other than
violations  that have been,  or will before the Closing have been,  corrected by
post-issuance  filings.  All  of the  outstanding  shares  of the  Corporation's
capital stock are validly issued,  fully paid, and nonassessable.  Upon purchase
thereof  pursuant to the terms of this Agreement,  the Purchaser will have, good
and marketable  title to the Shares,  free and clear of all security  interests,
liens,   encumbrances,   or  other  restrictions  or  claims,  subject  only  to
restrictions as to marketability  imposed by securities laws.  Assuming that the
representations  in Section 3.6 are true and correct,  the  Corporation  has not
violated or will not violate any applicable  securities  laws in connection with
the offer or sale of the Shares to the Purchaser hereunder.

         (b) Except as noted on Schedule  2.2 or where the failure to file would
not have had or could not have a material and adverse effect on the Corporation,
the Corporation has filed all reports,  registrations  and statements,  together
with any amendments required to be made with respect thereto, that were required
to be filed with the SEC or any other  governmental  or  regulatory  authorities
having  jurisdiction over the Corporation.  All such reports,  registrations and
statements  filed  by the  Corporation  with the SEC or  other  such  regulatory
authority  are  collectively  referred to herein as the  "Reports."  As of their
respective  dates,  each Report  complied in all material  respects with all the
statutes,  rules and  regulations  enforced  or  promulgated  by the  regulatory
authority with which it was filed and did not contain any 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. The Corporation has not been notified that
any such Report was deficient in any material respect as to form or content.

2.3      SUBSIDIARIES.   The  Corporation  has  no  operating   subsidiaries  or
affiliated  companies  and  does  not  otherwise  own or  control,  directly  or
indirectly, any equity interest in any operating corporation or entity.

2.4      CONDUCT OF BUSINESS;  LIABILITIES. Except as set forth in Schedule 2.4,
the  Corporation  is not in default  under,  and no  condition  exists that with
notice or lapse of time would constitute a default of the Corporation  under (i)
any mortgage,  loan agreement,  evidence of  indebtedness,  or other  instrument
evidencing  borrowed  money to which the  Corporation is a party or by which the
Corporation or the properties of the Corporation are bound or (ii) any judgment,
order, or injunction of any court, arbitrator, or governmental agency that would
reasonably  be  expected  to  affect  materially  and  adversely  the  business,
financial  condition,  or results of  operations of the  Corporation  taken as a
whole.

2.5      FINANCIAL  STATEMENTS.   (a)  The  audited  balance  sheet  and  income
statement of the Corporation as of the 30th day of September,  1997, in the form
attached to this  Agreement as Exhibit  2.5(A) and the income  statement for the

Corporation.  Except where any failure would not have a material  adverse effect
on the  Corporation,  such Licenses are in full force and effect,  no violations
have been or are expected to have been recorded in respect of any such licenses,
and no proceeding is pending or, to the knowledge of the Corporation, threatened

and  validly  existing  under  the  laws of the  State of  Delaware  and has all
requisite corporate power and authority to enter into this Agreement and perform

<PAGE>

3.2      AUTHORIZATION.   The  execution,   delivery,  and  performance  by  the
Purchaser of this  Agreement  and all other  agreements  contemplated  hereby to
which the  Purchaser  is a party have been duly and  validly  authorized  by all
necessary  corporate  action of the Purchaser,  and this Agreement and each such
other  agreement,  when  executed  and  delivered by the parties  thereto,  will
constitute the legal, valid, and binding obligation of the Purchaser enforceable
against it in accordance with its terms, except as enforceability may be limited
by applicable bankruptcy,  insolvency, and similar statutes affecting creditors'
rights generally and judicial limits on equitable remedies.

3.3      NO  CONFLICT  WITH OTHER  INSTRUMENTS  OR  AGREEMENTS.  The  execution,
delivery,  and  performance  by the  Purchaser of this  Agreement  and all other
agreements contemplated hereby to which the Purchaser is a party will not result
in a breach or  violation  of, or  constitute a default  under,  its Articles of
Incorporation  or Bylaws or any material  agreement to which the  Purchaser is a
party or by which the Purchaser is bound.

3.4      GOVERNMENTAL AUTHORITIES.  Except as set forth in Schedule 3.4, (i) the
Purchaser is not required to submit any notice, report, or other filing with any
governmental  or  regulatory  authority in  connection  with the  execution  and
delivery by the Purchaser of this Agreement and the consummation of the purchase
and  (ii)  no  consent,  approval,  or  authorization  of  any  governmental  or
regulatory  authority  is  required  to be  obtained  by  the  Purchaser  or any
affiliate  in  connection  with  the  Purchaser's   execution,   delivery,   and
performance of this Agreement and the consummation of this purchase.

3.5      LITIGATION.  There are no actions, suits, proceedings,  or governmental
investigations  or  inquiries  pending or, to the  knowledge  of the  Purchaser,
threatened  against the  Purchaser or its  properties,  assets,  operations,  or
businesses  that  might  delay,  prevent,  or hinder  the  consummation  of this
purchase.

3.6      INVESTMENT REPRESENTATIONS

         3.6.1  The  Purchaser  is  a   corporation   in  good  standing  and  a
sophisticated  investor  that  has  substantial  experience  in  evaluating  and
investing in private  placement  transactions of securities in companies similar
to the Corporation so that the Purchaser is capable of evaluating the merits and
risks of the  Purchaser's  investment in the Corporation and has the capacity to
protect the Purchaser's own interests.

         3.6.2 The  Purchaser is  acquiring  the Shares for  investment  for the
Purchaser's own account, not as a nominee or agent, and not with the view to, or
for  resale  in  connection  with,  any  distribution   thereof.  The  Purchaser
understands  that the Shares to be purchased have not been registered  under the
Securities Act of 1933 ("Securities Act") or the securities laws of any state by
reason  of  a  specific  exemption  from  the  registration  provisions  of  the
Securities Act and the applicable  state  securities  laws, the  availability of
which depends upon,  among other things,  the bona fide nature of the investment
intent and the accuracy of the Purchaser's  representations as expressed herein.
The Purchaser is acquiring the Shares without  expectation,  desire, or need for
resale  and not with the  view  toward  distribution,  resale,  subdivision,  or
fractionalization of the Shares except as provided under the Registration Rights
Agreement.

         3.6.3 The Purchaser  understands  that the Shares to be purchased  have
not been registered  under Securities Act, or under any state securities law and
will contain a legend to that effect.

         3.6.4 The Purchaser  understands  that the Shares cannot be resold in a
transaction to which the Securities Act and state  securities  laws apply unless
(i)  subsequently  registered  under the  Securities  Act and  applicable  state
securities laws or (ii) exemptions from such  registrations  are available.  The
Purchaser  is  aware  of the  provisions  of  Rule  144  promulgated  under  the
Securities  Act which  permit  limited  resale of shares  purchased in a private
transaction subject to the satisfaction of certain conditions.

3.7      TAX  LIABILITY.  To the  extent  the  Purchaser  deems  necessary,  the
Purchaser has reviewed with the Purchaser's own tax advisors the federal, state,
local and foreign  tax  consequences  of this  investment  and the  transactions

                                       13
<PAGE>

contemplated by this Agreement. The Purchaser relies solely on such advisors and
not on any  statements  or  representations  of  the  Corporation  or any of its
agents.  The Purchaser  understands that the Purchaser (and not the Corporation)
shall be responsible  for the  Purchaser's own tax liability that may arise as a
result of this investment or the transactions contemplated by this Agreement.

3.8      DISCLOSURE.  To the Purchaser's  knowledge,  this  Agreement,  with the
Exhibits hereto, when taken as a whole, does not contain any untrue statement of
a material  fact  concerning  the  Purchaser  or omit to state a  material  fact
necessary in order to make the  statements  concerning  the Purchaser  contained
herein not misleading in light of the circumstances under which they were made.

3.9      LITIGATION.  There are no actions, suits, proceedings or investigations
pending against the Purchaser or the Purchaser's  properties before any court or
governmental  agency (nor,  to the  Purchaser's  knowledge,  is there any threat
thereof) which would impair in any way the Purchaser's ability to enter into and
fully perform the Purchaser's  commitments and obligations  under this Agreement
or the transactions contemplated hereby.

3.10     COMPLIANCE  WITH  OTHER  INSTRUMENTS.   The  execution,   delivery  and
performance of and compliance  with this  Agreement,  and the issuance of shares
will not result in any material  violation of, or conflict with, or constitute a
material default under,  any Purchaser's  articles of incorporation or bylaws or
any of the  Purchaser's  material  agreements  nor result in the creation of any
mortgage,  pledge,  lien,  encumbrance  or charge  against  any of the assets or
properties of the Corporation or the Shares.

Section 4. COVENANTS OF CORPORATION. The Corporation  covenants and agrees with
the Purchaser that upon the reasonable request of the Purchaser hereto after the
Closing, the Corporation will take all action and will execute all documents and
instruments  necessary  or  desirable  to  consummate  and give  effect  to this

into this Agreement and purchase the Shares, the Corporation agrees to:

         5.1.1 provide for the resignation of the current Board of Directors and
the  appointment  of the  Purchaser's  nominees to the Board of Directors of the
Corporation;

         5.1.2 take such actions as are necessary to qualify and  facilitate the
issuance of the Shares  without a shareholder  vote under any applicable law and
the rules and regulations of the applicable Nasdaq market system; and

         5.1.3 provide prompt  reimbursement by the Corporation to the Purchaser
for all reasonable legal and other out-of-pocket expenses incurred in connection
with the completion of this transaction.

         5.1.4  indemnify  the  Purchaser  from and against all losses,  claims,
expenses  and  liabilities  arising  out of any  breach of any  representations,
warranties,  covenants and agreements made by the Corporation in this Agreement.
Purchaser  understands  and agrees  that the  foregoing  indemnification  is the
Purchaser's  sole  and  exclusive  remedy  with  respect  to any  breach  of any

                                       14
<PAGE>

representations, warranties, covenants and agreements made by the Corporation in
this  Agreement,  except to the extent such  breach  could be expected to have a
material adverse effect on the future  operations or financial  condition of the
Corporation.

                  5.2 As a material  inducement to the Corporation to enter into
this  Agreement  and  issue the  Shares,  the  Purchaser  agrees to use its best
efforts to cause the  Corporation  to maintain  director  and officer  liability
coverage  in  substantially  the same  amounts and with  substantially  the same
coverages as that maintained by the Corporation on the Closing Date for at least
three years.

SECTION 6.        RELEASE.  Dr. T. Colin Campbell, a principal in the Purchaser,
agrees not to pursue his claims in C.A. No. 15072 BB in the Court of Chancery in
New Castle County,  State of Delaware (the "Lawsuit").  Dr. Campbell understands
that this  Agreement  is a full and final  release of all  claims  stated in the
Lawsuit, including any claims which he may have or may contend that he may have,
and Dr. Campbell further understands that he is releasing all claims arising out
of or related to the Lawsuit that are known, unknown, suspected and unsuspected.

SECTION 7.        CONDITIONS PRECEDENT TO THE OBLIGATIONS OF PURCHASER. Each and
every  obligation  of the  Purchaser  under  this  Agreement  is  subject to the
condition, at or before the Closing, that the Corporation will have furnished to
the Purchaser a certificate  of an officer of the  Corporation  that its present
legal counsel has been instructed to deliver all files of the Corporation in its
possession  to the  Purchaser  and, to the best of the knowledge of the officer,
all documents of the Corporation have been provided to the Purchaser.

its conditions to consummate  this purchase have been  satisfied or waived,  the
Corporation  shall deliver to the Purchaser the  certificate(s)  evidencing  the
Shares,  and the Purchaser  shall deliver to the Corporation the monies referred
to in  Section  1.3,  in a manner to be agreed  upon by the  parties.  After the
Closing, the Corporation will execute, deliver, and acknowledge all such further
instruments  of transfer and  conveyance and will perform all such other acts as
the Purchaser may reasonably request to effectively transfer the Shares.

8.2      CONSUMMATION  OF  CLOSING.  All  acts,  deliveries,  and  confirmations
comprising the Closing  regardless of chronological  sequence shall be deemed to
occur  contemporaneously and simultaneously upon the occurrence of the last act,
delivery, or confirmation of the Closing and none of such acts,  deliveries,  or
confirmations  shall be  effective  unless  and until the last of the same shall
have occurred. The time of the Closing has been scheduled to correspond with the
close of business at the principal office of the Corporation and,  regardless of
when the last act,  delivery,  or  confirmation of the Closing shall take place,
the  transfer of the Shares shall be deemed to occur as of the close of business
at the principal office of the Corporation on the date of the Closing.

                  THIS  CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE SECURITIES
                  ACT  OF  1933.   THE   CORPORATION   WILL  NOT  TRANSFER  THIS
                  CERTIFICATE  UNLESS  (i)  THERE IS AN  EFFECTIVE  REGISTRATION
                  COVERING THE SHARES  REPRESENTED BY THIS CERTIFICATE UNDER THE

                  LAWS,  (ii) IT  FIRST  RECEIVES  A  LETTER  FROM AN  ATTORNEY,

                  EXEMPT FROM REGISTRATION  UNDER THE SECURITIES ACT OF 1933 AND
                  UNDER  ALL  APPLICABLE  STATE  SECURITIES  LAWS,  OR (iii) THE
                  TRANSFER IS MADE PURSUANT TO RULE 144 UNDER THE SECURITIES ACT
                  OF 1933.

         3.       NOTICE OF PROPOSED TRANSFER. Prior to any proposed transfer of
any Restricted Stock or other shares of capital stock of the Company (other than
under the circumstances  described in Sections 4 or 5), the Holder thereof shall
give written  notice to the Company of its  intention  to effect such  transfer.
Each such notice  shall  describe the manner of the  proposed  transfer  and, if
requested  by the  Company,  shall  be  accompanied  by an  opinion  of  counsel
reasonably  satisfactory to the Company to the effect that the proposed transfer
may be effected  without  registration  under the Securities Act,  whereupon the
Holder of such stock shall be entitled to transfer such stock in accordance with
the terms of its  notice;  PROVIDED,  HOWEVER,  that no such  opinion of counsel
shall be required for a transfer to one or more partners of the  transferor  (in
the case of a  transferor  that is a  partnership)  or to a parent  corporation,
subsidiary  corporation or to a corporation which is under common control with a
transferor (in the case of a transferor  that is a  corporation,  to a member of
the transferor's  immediate family or other descendant of the transferor or to a
trust or other  entity  for the  benefit  of the  transfer  and/or  such  person
provided that in such case the transferee(s) remain bound hereby).

         4.       REQUIRED  REGISTRATION.  (a) At any  time  within  six  months
following the date of this  Agreement,  one or more Holders of Restricted  Stock
constituting  at least sixty  percent  (60%) of the total  shares of  Restricted
Stock then  outstanding may request the Company to register under the Securities
Act all or any portion of the shares of Restricted Stock held by such requesting
Holder or Holders ("Initiating Holders").

                  (b) Notwithstanding anything to the contrary contained in this
Section 4, no request may be made under this Section 4 within one hundred eighty
(180) days after the effective  date of a  registration  statement  filed by the
Company other than on Form S-4 or S-8 or their successor forms.

                  (c) If at the time of any request to register Restricted Stock
pursuant  to this  Section 4 (i) the  Company is  engaged or has fixed  plans to
engage within sixty (60) days of the time of the request in a registered  public
offering  of its  securities,  (ii) the  Company is in  possession  of  material
non-public  information  the  public  disclosure  of  which,  in the good  faith
determination  of  the  Company's  Board  of  Directors,  would  materially  and
adversely  affect the  Company,  (iii) the Company  shall have  delivered to the
Holders of Restricted  Stock that have requested a registration a certificate of

                                       2
<PAGE>

an officer of the  Company to the effect  that,  on the advice of  counsel,  the
Company  believes such delay is necessary to comply with  Regulation M under the
Exchange Act, or (iv) the Company is engaged in any other activity which, in the
good faith determination of the Company's Board of Directors, would be adversely
affected by the requested registration to the material detriment of the Company,
then the  Company may at its option  direct  that such  request be delayed for a
reasonable  period not in excess of one hundred  twenty (120) days from the time
of such  request  to  register  Restricted  Stock  pursuant  to this  Section 4;
PROVIDED,  HOWEVER,  that such right to delay a request may be  exercised by the
Company not more than once in any  twelve-month  period.  Such  delay,  however,
shall not in any way restrict the Holders from exercising piggyback registration
rights under Section 5 during such period.

                  (d) Following  receipt of any notice under this Section 4, the
Company  shall  immediately  notify all  Holders of  Restricted  Stock from whom
notice has not been received,  and such Holders shall be entitled  within thirty
(30) days  thereafter  to  request  the  Company  to  include  in the  requested
registration all or any portion of their shares of Restricted Stock. The Company
shall use its best efforts to register under the Securities Act, for public sale
in  accordance  with the method of  disposition  specified  in the  notice  from
requesting  Holders,  the number of shares of Restricted Stock specified in such
notice (and in all notices  received by the Company  from other  Holders  within
thirty (30) days after the giving of such notice by the Company). If such method
of  disposition  shall be an  underwritten  public  offering,  the  Holders of a
majority  of the  shares of  Restricted  Stock to be sold in such  offering  may
designate the managing underwriter of such offering,  subject to the approval of
the  Company,  which  approval  shall not be  unreasonably  withheld or delayed.
Notwithstanding  any  other  provision  of this  Section  4, if the  underwriter
advises the  Initiating  Holders in writing  that  marketing  factors  require a
limitation  of the  number  of shares to be  underwritten,  then the  Initiating
Holders shall so advise all Holders of Restricted Stock which would otherwise be
underwritten  pursuant hereto, and the number of shares of Restricted Stock that
may be  included  in the  underwriting  shall be  allocated  among  all  Holders
thereof,   including  the  Initiating  Holders,  in  proportion  (as  nearly  as
practicable)  to the amount of  Restricted  Stock of the  Company  owned by each
Holder;  PROVIDED,  HOWEVER, that the number of shares of Restricted Stock to be
included in such  underwriting  shall not be reduced unless all other securities
are first entirely excluded from the underwriting.

                  (e) The Company  shall be  obligated  to  register  Restricted
Stock pursuant to this Section 4, on only one (1) occasion;  PROVIDED,  HOWEVER,
that  such  obligation  shall  be  deemed  satisfied  only  when a  registration
statement  covering all shares of Restricted Stock specified in notices received
as aforesaid, for sale in accordance with the method of disposition specified by
the  requesting  Holders  shall have  become  effective  and,  if such method of
disposition is a firm commitment  underwritten public offering,  all such shares
shall have been sold pursuant thereto, unless a failure was caused by a Holder.

                  (f) Except for registration statements on Form S-4, S-8 or any
successor  forms thereto,  and unless the Company (i) has  previously  given the
notice  referred  to in  Section 5 or (ii) has  exercised  its rights to delay a
requested  registration  under  Section  4(c)(i)  and  within  the  time  period
prescribed  in Section  4(c) files a  registration  statement  with respect to a
registered public offering of it securities,  the Company will not file with the
Commission any other registration  statement with respect to a registered public
offering of its  securities,  the Company will not file with the  Commission any
other  registration  statement  under the  Securities Act with respect to Common
Stock, whether for its own account or that of other stockholders,  from the date
of receipt of a notice from requesting  Holders pursuant to this Section 4 until
the completion of the period of  distribution of the  registration  contemplated
thereby.

         5.       PIGGYBACK REGISTRATION.  (a) If the Company at any time (other
than  pursuant  to Section 4 or Section  13)  proposes  to  register  any of its
securities under the Securities Act for sale to the public,  whether for its own
account  or for the  account of other  security  holders  or both  (except  with
respect to  registration  statements  on Forms S-4, S-8 or any  successor  forms
thereto),  each  such  time  it will  give  written  notice  to all  Holders  of
outstanding Restricted Stock of its intention so to do; PROVIDED HOWEVER that no
such notice  shall be required  after such time that the Company  ceases to have
registration  obligations  under this Section 5. Upon the written request of any
such  Holder,  received by the Company  within ten (10) days after the giving of

                                       3
<PAGE>

any such notice by the Company,  to register any of its Restricted  Stock (which
request shall state the intended  method of  disposition  thereof),  the Company
will use its best efforts to cause the Restricted Stock as to which registration
shall have been so requested to be included in the  securities  to be covered by
the  registration  statement  proposed  to be filed by the  Company,  all to the
extent  required  to permit  the sale or other  disposition  by the  Holder  (in
accordance with its written request) of such Restricted Stock so registered.

                  (b) If any  registration  pursuant to this Section 5 shall be,
in whole or in part, an underwritten public offering of Common Stock, the number
of shares of  Restricted  Stock to be  included in such an  underwriting  may be
reduced pro rata among the requesting Holders based upon the number of shares of
Restricted  Stock owned by such  Holders if and to the extent that the  managing
underwriter  shall be of the opinion that such inclusion would adversely  affect
the  marketing of the  securities to be sold by the Company  therein;  PROVIDED,
HOWEVER,  that:  (1) if the Company  registers any of its securities for its own
account in such  underwriting,  such number of shares of Restricted  Stock shall
not be reduced if any shares are to be  included  in such  underwriting  for the
account of any person other than the Company or requesting Holders of Restricted
Stock or (2) if the Company does not register any of its  securities for its own
account in such  underwriting,  the number of shares of  Restricted  Stock to be
included in such  underwriting  shall not be reduced unless all other securities
are first  entirely  excluded from the  underwriting  unless the Holders of more
than 60% of the  Restricted  Securities  consent to the  inclusion of such other
securities.

                  (c) Notwithstanding  the foregoing  provisions of this Section
5, the Company  may  withdraw  any  registration  statement  referred to in this
Section 5 without  thereby  incurring any liability to the Holders of Restricted
Stock.

         6.       OBLIGATIONS  OF THE  COMPANY.  If and  whenever the Company is
required by the  provisions  of Section 4 or 5 to use its best efforts to effect
the registration of any shares of Restricted Stock under the Securities Act, the
Company will, as expeditiously as possible:

                  (a)  prepare  and file  with  the  Commission  a  registration
statement  (which,  in the case of an underwritten  public offering  pursuant to
Section  4,  shall  be on  Form  S-1 or  other  form  of  general  applicability
satisfactory  to the managing  underwriter  selected as therein  provided)  with
respect to such  securities and use its best efforts to cause such  registration
statement  to become and  remain  effective  for the period of the  distribution
contemplated thereby (determined as hereinafter provided);

                  (b) 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
until completion of the period of distribution and comply with the provisions of
the  Securities  Act with respect to the  disposition  of all  Restricted  Stock
covered by such registration  statement in accordance with the sellers' intended
method of disposition set forth in such registration statement for such period;

                  (c)  furnish to each  seller of  Restricted  Stock and to each
underwriter  such  number  of  copies  of the  registration  statement  and  the
prospectus  included  therein  (including each  preliminary  prospectus) as such
person  reasonably  may request in order to facilitate  the public sale or other
disposition of the Restricted Stock covered by such registration statement;

                  (d) use its best efforts to register or qualify the Restricted
Stock covered by such registration  statement under the securities or "blue sky"
laws of such jurisdictions as the sellers of Restricted Stock or, in the case of
an underwritten  public  offering,  the managing  underwriter  reasonably  shall
request;  PROVIDED,  HOWEVER, that the Company shall not for any such purpose be
required to qualify generally to transact  business as a foreign  corporation in
any  jurisdiction  where it is not so qualified or to consent to general service
of process in any such jurisdiction;

                  (e) use its best efforts to list the Restricted  Stock covered
by such registration  statement with any securities exchange on which the Common
Stock of the Company is then listed;

                                       4
<PAGE>

                  (f)  immediately  notify each seller of  Restricted  Stock and
each  underwriter  under  such  registration  statement,  at  any  time  when  a
prospectus  relating  thereto is required to be delivered  under the  Securities
Act,  of the  happening  of any event of which the Company  has  knowledge  as a
result of which the prospectus contained in such registration statement, as then
in effect,  includes an untrue  statement of a material fact or omits to state a
material fact required to be stated  therein or necessary to make the statements
therein not misleading in light of the circumstances then existing;

                  (g) if the offering is underwritten  and at the request of any
seller of  Restricted  Stock,  use its best  efforts to furnish on the date that
Restricted  Stock is delivered  to the  underwriters  for sale  pursuant to such
registration: (i) an opinion dated such date of counsel representing the Company
for the purposes of such registration, addressed to the underwriters and to such
seller,  stating that such registration statement has become effective under the
Securities Act and that (A) to the best knowledge of such counsel, no stop order
suspending the effectiveness thereof has been issued and no proceedings for that
purpose have been instituted or are pending or contemplated under the Securities
Act, (B) the registration  statement,  the related prospectus and each amendment
or  supplement  thereof  comply  as to form in all  material  respects  with the
requirements  of the  Securities  Act (except that such counsel need not express
any opinion as to financial  statements contained therein) and (C) to such other
effects as  reasonably  may be requested by counsel for the  underwriters  or by
such  seller  or its  counsel,  and  (ii) a  letter  dated  such  date  from the
independent  public  accountants  retained  by  the  Company,  addressed  to the
underwriters  and to such  seller,  stating  that  they are  independent  public
accountants within the meaning of the Securities Act and that, in the opinion of
such  accountants,  the  financial  statements  of the  Company  included in the
registration  statement  or the  prospectus,  or  any  amendment  or  supplement
thereof,  comply  as to  form  in all  material  respects  with  the  applicable
accounting   requirements   of  the  Securities   Act,  and  such  letter  shall
additionally cover such other financial matters (including information as to the
period  ending  no more than five (5)  business  days  prior to the date of such
letter) with respect to such  registration as such  underwriters  reasonably may
request; and

                  (h) make available for inspection by each seller of Restricted
Stock,  any  underwriter  participating  in any  distribution  pursuant  to such
registration statement, and any attorney,  accountant or other agent retained by
such seller or underwriter, all financial and other records, pertinent corporate
documents  and  properties  of the Company,  and cause the  Company's  officers,
directors and employees to supply all  information  reasonably  requested by any
such seller, underwriter,  attorney, accountant or agent in connection with such
registration  statement,  subject to each party's obligations not to disclose or
misuse any confidential information disclosed to it.

                           For  purposes of Sections  4(f),  6(a) and 6(b),  the
period of  distribution of Restricted  Stock in a firm  commitment  underwritten
public  offering shall be deemed to extend until each  underwriter has completed
the  distribution  of  all  securities  purchased  by  it,  and  the  period  of

claims,  damages  or  liabilities,  joint  or  several,  to which  such  seller,
underwriter or controlling person may become subject under the Securities Act or

under  which such  Restricted  Stock was  registered  under the  Securities  Act
pursuant  hereto,  any  preliminary  prospectus  or final  prospectus  contained

and will  reimburse  each  such  seller,  each  such  underwriter  and each such
controlling person for any legal or other expenses  reasonably  incurred by them
in connection  with  investigating  or defending any such loss,  claim,  damage,

any such  case if and to the  extent  that  any  such  loss,  claim,  damage  or
liability  arises out of or is based upon an untrue  statement or alleged untrue
statement or omission or alleged omission so made in conformity with information
furnished  by any such  seller,  any such  underwriter  or any such  controlling
person  in  writing  specifically  for use in  such  registration  statement  or
prospectus.

                  (b) In the event of a  registration  of any of the  Restricted
Stock under the Securities Act pursuant  hereto,  each seller of such Restricted
Stock thereunder severally and not jointly, will indemnify and hold harmless the
Company, each person, if any, who controls the Company within the meaning of the
Securities  Act,  each  officer  of  the  Company  who  signs  the  registration
statement,  each director of the Company, each other seller of Restricted Stock,
each underwriter and each person who controls any underwriter within the meaning
of the Securities Act, against all losses, claims, damages or liabilities, joint
or  several,  to which the  Company or such  officer,  director,  other  seller,
underwriter or controlling person may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect  thereof) arise out of or are based upon any untrue statement or alleged
untrue  statement of any material fact contained in the  registration  statement

incurred by them in connection  with  investigating  or defending any such loss,
claim, damage, liability or action, PROVIDED,  HOWEVER, that such seller will be
liable  hereunder in any such case if and only to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue  statement or omission or alleged  omission made in reliance upon
and in conformity with information pertaining to such seller, as such, furnished
in  writing  to the  Company  by  such  seller  specifically  for  use  in  such
registration statement or prospectus, and PROVIDED FURTHER that the liability of
each seller hereunder shall not apply to amounts paid in settlement without such
seller's prior written consent.

                  (c) Promptly after receipt by an indemnified  party  hereunder
of notice of the commencement of any action,  such indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party hereunder,
notify the indemnifying party in writing thereof,  but the omission so to notify
the indemnifying party shall not relieve it from any liability which it may have
to such indemnified party other than under this Section 10 and shall only relive
it from any  liability  which it may have to such  indemnified  party under this
Section 10 if and to the extent the  indemnifying  party is  prejudiced  by such
omission. In case any such action shall be brought against any indemnified party
and it shall notify the  indemnifying  party of the  commencement  thereof,  the
indemnifying  party shall be entitled  to  participate  in and, to the extent it
shall  wish,  to  assume  and   undertake  the  defense   thereof  with  counsel
satisfactory to such indemnified  party, and, after notice from the indemnifying
party to such  indemnified  party of its election so to assume and undertake the
defense thereof,  the indemnifying party shall not be liable to such indemnified
party under this Section 10 for any legal expenses subsequently incurred by such
indemnified  party in connection  with the defense thereof other than reasonable
costs of  investigation  and of  liaison  with  counsel so  selected,  PROVIDED,

                                       6
<PAGE>


HOWEVER, that, if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded  that  there  may be  reasonable  defenses  available  to it which are
different from or additional to those available to the indemnifying  party or if
the interests of the indemnified party reasonably may be deemed to conflict with
the interests of the indemnifying  party,  the indemnified  party shall have the
right to  select a  separate  counsel  and to assume  such  legal  defenses  and
otherwise to  participate  in the defense of such action,  with the expenses and
fees of such separate counsel and other expenses  related to such  participation
to be reimbursed by the indemnifying party as incurred.

                  (d) In order to provide for just and equitable contribution to
joint  liability  under the  Securities  Act in any case in which either (i) any
Holder of  Restricted  Stock  exercising  rights  under this  Agreement,  or any
controlling  person  of any  such  Holder,  makes  a claim  for  indemnification
pursuant to this Section 10 but it is judicially  determined  (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to  appeal  or the  denial  of the  last  right  of  appeal)  that  such
indemnification  may not be enforced in such case  notwithstanding the fact that
this Section 10 provides for  indemnification in such case, or (ii) contribution
under the  Securities Act may be required on the part of any such selling Holder
or any such controlling  person in circumstances  for which  indemnification  is
provided  under this  Section 10; then,  and in each such case,  the Company and
such  Holder  will  contribute  to the  aggregate  losses,  claims,  damages  or
liabilities  to which they may be subject  (after  contribution  from others) in
such proportion so that such Holder is responsible  for the portion  represented
by the percentage that the public offering price of its Restricted Stock offered
by  the  registration  statement  bears  to the  public  offering  price  of all
securities  offered  by  such  registration   statement,   and  the  Company  is
responsible for the remaining portion; PROVIDED, HOWEVER, that, in Section 11(f)
of the  Securities  Act) will be  entitled  to  contribution  from any person or
entity who was not guilty of such fraudulent misrepresentation.

                  (e)  Notwithstanding  the  foregoing,  to the extent  that the
provisions on  indemnification  and  contribution  contained in the underwriting
agreement  entered into in connection with the underwritten  public offering are
in conflict with the foregoing  provisions,  the provisions in the  underwriting
agreement shall control.

                  (f) The  obligations  of the Company  and  Holders  under this
Section 10 shall survive the completion of any offering of Restricted Stock in a
registration  statement  under  Section  4,  5 or  13  of  this  Agreement,  and
otherwise.

         11.      CHANGES IN COMMON STOCK OR PREFERRED  STOCK.  If, and as often
as,  there is any change in the Common  Stock of Common  Stock by way of a stock
split,  stock dividend,  combination or  reclassification,  or through a merger,
consolidation,  reorganization  or  recapitalization,  or by  any  other  means,
appropriate adjustment shall be made in the provisions hereof so that the rights
and privileges granted hereby shall continue with respect to the Common Stock as
so changed.

         12.      RULE  144  REPORTING.  With a view  to  making  available  the
benefits of certain rules and  regulations  of the  commission  which may at any
time permit the sale of the Restricted Stock to the public without registration,
at all times after ninety (90) days after any registration  statement covering a
public offering of securities of the Company under the Securities Act shall have
become effective, the Company agrees to:

                  (a) make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act;

                  (b) file with the  Commission  in a timely  manner all reports
and other  documents  required of the Company under the  Securities  Act and the
Exchange Act; and;

                  (c) furnish to each Holder of Restricted  Stock forthwith upon
request  a  written  statement  by the  Company  as to its  compliance  with the
reporting  requirements  of  such  Rule  144 and of the  Securities  Act and the
Exchange  Act,  a copy of the most  recent  annual  or  quarterly  report of the
Company,  and such other  reports and  documents so filed by the Company as such
Holder may  reasonably  request in availing  itself of any rule or regulation of
the  Commission  allowing  such  Holder  to sell any  Restricted  Stock  without
registration.

         13.      TRANSFERABILITY  OF REGISTRATION  RIGHTS. The rights conferred
herein on the Holders of  Restricted  Stock shall only inure to the benefit of a
transferee of Restricted Stock, (i) if the transfer was approved by the Board of
Directors of the Company (which approval shall not be unreasonably withheld) and
there is transferred to such transferee all of the Restricted Stock then held by
the  transferor  or (ii) if the  transferee  is a  transferee  permitted  in the
