to which  Abrika or the General  Partner is a party or by which it is  otherwise
bound  that  provide  for the  repurchase,  sale or  issuance  by  Abrika of any

(ii)  below)  by  virtue  of such  Person's  interest  in  Abrika  to  share  or
participate in any of the management,  profits,  losses or capital of Abrika. As

validly issued to Par, free and clear of all liens, mortgages, pledges, charges,

otherwise in effect in connection with the sale of the  Partnership  Interest or
the Note  (including any  conversion  thereof) to Par or otherwise in respect of

                    (iii) No Person has any demand, "piggy-back" or other rights
to cause Abrika to file any  registration  statement under the Securities Act of
1933, as amended (the "SECURITIES ACT"),  relating to any partnership  interests
or other  securities  of  Abrika  or to  participate  in any  such  registration
statement.

               (b)  ORGANIZATION; GOOD STANDING; POWER.

                    (i)   Abrika is a limited liability limited partnership duly
organized,  validly existing and in good standing under the laws of the State of
Florida,  and has the partnership  power and authority to own, lease and operate
its assets and properties  and to carry on its business as presently  conducted.
Abrika  is duly  qualified  to  transact  business  in the  states  set forth on
SCHEDULE  3.1(b)  of the  Disclosure  Letter.  There  are  no  other  states  or
jurisdictions  in which the  character and location of the  properties  owned or
leased by Abrika and/or the conduct of its business make any such  qualification
to transact business necessary,  except any where the failure to be so qualified
would not have a material adverse effect on the business, operations,  condition
(financial  or other) or prospects of Abrika or the value of its  properties  or
assets, taken as a whole (a "MATERIAL ADVERSE EFFECT"). Abrika's records contain
true and complete  recordings  of all actions by vote or written  consent of the
holders of limited  partnership  interests in Abrika and the General Partner, as
to which formal action was required to have been, or was in fact,  taken by such
holders or the General Partner.

                    (ii)  The  General Partner  is a limited  liability  limited
partnership duly organized, validly existing and in good standing under the Laws
of the State of Florida, and has the partnership power and authority to carry on
its  business  as  presently  conducted.  The  execution  and  delivery  of this
Agreement, the Collaboration Agreement and the Investors Rights Agreement by the
General  Partner  on  behalf  of  Abrika,  and  the  execution  of  the  Amended
Partnership  Agreement have been duly authorized by all necessary  action on the
part  of the  General  Partner,  and  the  General  Partner  has  all  necessary
partnership  power with respect  thereto.  Mr. Cohen controls the management and
affairs of ABRIKA  GPNER,  LLC,  which,  in turn,  controls the  management  and
affairs of the General Partner.

                                      -4-


               (c)  AUTHORITY;   VALIDITY;  NO  CONFLICTS.   The  execution  and
delivery by Abrika of this Agreement, the Collaboration Agreement, the Investors
Rights  Agreement and the Amended  Partnership  Agreement,  the  performance  by
Abrika of its obligations hereunder and thereunder,  and the consummation of the
transactions  contemplated hereby and thereby,  have been duly authorized by all
necessary partnership action on the part of Abrika, and Abrika has all necessary
partnership power with respect thereto. This Agreement and such other agreements
have been (or will be) duly executed and delivered by Abrika and, subject to the
due  authorization,  execution  and  delivery of this  Agreement  and such other
agreements by Par, constitute (or will constitute) valid and binding obligations
of Abrika, enforceable against Abrika in accordance with their respective terms,
except to the  extent  that  enforceability  thereof  may be  limited by general
equitable principles or the operation of bankruptcy, insolvency, reorganization,
fraudulent  transfer,  moratorium  or similar  Laws.  Neither the  execution and
delivery  by  Abrika  of  this  Agreement  or  such  other  agreements,  nor the
consummation  of the  transactions  contemplated  hereby  or  thereby,  nor  the
performance by Abrika of its obligations hereunder or thereunder, will (or, with
the  giving  of  notice or the lapse of time or both,  would):  (i)  subject  to
Abrika's  obtaining  the Rights  Waiver/Consent,  conflict  with or violate  any
provision of the Partnership Agreement;  (ii) give rise to a conflict, breach or
default,  or any right of termination,  cancellation or acceleration of remedies
or rights,  or  otherwise  result in a loss of  benefits  to  Abrika,  under any
material note, bond, mortgage, indenture, license, agreement or other instrument
or obligation to which Abrika is a party or by which it or any of its properties
or assets is otherwise bound; or (iii) violate any Law.

          For purposes of this  Agreement,  the phrase "THE KNOWLEDGE OF ABRIKA"
or words of similar  import  relating to the  knowledge  or  awareness of Abrika
means facts or other  information  actually  known by the General  Partner,  Mr.
Cohen or any senior officer of Abrika.

               (d)  INTERESTS IN OTHER ENTITIES. Except as set forth on SCHEDULE
3.1(d) of the Disclosure  Letter,  Abrika does not, directly or indirectly,  (i)
own, of record or beneficially,  any shares of voting stock or equity securities
of any Person; (ii) have any other ownership, equity or debt interest, of record
or beneficially,  in any Person;  or (iii) have any obligation or plan, fixed or
contingent, to purchase or subscribe for any interest in, advance or loan monies
to, or in any way make an  investment  in,  any  Person or to share any  profits
generally or capital of any other Person.

               (e)  GOVERNMENTAL  AUTHORIZATIONS;  THIRD-PARTY CONSENTS.  Except

          3.2  REPRESENTATIONS  AND WARRANTIES OF PAR. Par hereby represents and
warrants to Abrika as follows:

               (a)  ORGANIZATION AND POWER. Par is a corporation duly organized,
validly  existing and in good standing  under the Laws of the State of Delaware,
and has the corporate  power and authority to own,  lease and operate its assets
and properties and to carry on its business as presently conducted.

               (b)  AUTHORITY;   VALIDITY;  NO  CONFLICTS.   The  execution  and
delivery by Par of this Agreement,  the Collaboration  Agreement,  the Investors
Rights Agreement and the Amended Partnership  Agreement,  the performance by Par
of its  obligations  hereunder  and  thereunder,  and  the  consummation  of the

                                      -12-


transactions  contemplated hereby and thereby,  have been duly authorized by all
necessary  corporate  action  on the  part  of Par,  and  Par has all  necessary
corporate power with respect  thereto.  This Agreement and such other agreements
to which  it  shall  become a party  have  been (or will be) duly  executed  and
delivered by Par and, subject to the due  authorization,  execution and delivery
of this  Agreement  and such other  agreements  by Abrika,  constitute  (or will
constitute) the valid and binding obligations of Par, enforceable against Par in
accordance with their respective terms, except to the extent that enforceability
thereof  may be limited by general  equitable  principles  or the  operation  of
bankruptcy,  insolvency,  reorganization,  fraudulent  transfer,  moratorium  or
similar Laws.  Neither the  execution  and delivery by Par of this  Agreement or
such other  agreements,  nor the consummation of the  transactions  contemplated
hereby or thereby,  nor the performance by Par of its  obligations  hereunder or
thereunder,  will (or,  with the  giving of notice or the lapse of time or both,
would) (i)  conflict  with or violate  any  provision  of Par's  certificate  of
incorporation or bylaws; or (ii) violate any Law.

               (c)  LITIGATION.  There are no actions  pending to which Par is a
party that seek to prevent, enjoin, alter or delay the transactions contemplated
by this Agreement.

               (d)  PURCHASE FOR OWN ACCOUNT.  The Partnership  Interest and the
Note  (collectively,  the  "SECURITIES")  are being  acquired for investment for
Par's own account,  not as a nominee or agent, and not with a view to the public
resale or distribution thereof within the meaning of the Securities Act.

               (e)  INVESTMENT EXPERIENCE.  Par understands that the purchase of
the Securities  involves  substantial risk. Par has experience as an investor in
securities of companies and  acknowledges  that it can bear the economic risk of
its  investment  in the  Securities  and has such  knowledge  and  experience in
financial or business  matters that it is capable of  evaluating  the merits and
risks of this  investment in the  Securities and protecting its own interests in
connection with such investment.

               (f)  RELIANCE UPON  PURCHASER'S REPRESENTATIONS.  Par understands
that the issuance and sale of the Securities to it will not be registered  under
the Securities Act on the ground that such issuance and sale will be exempt from
registration under the Securities Act pursuant to Section 4(2) thereof, and that
Abrika's reliance on such exemption is based, in part, on Par's  representations
set forth herein.

               (g)  RECEIPT OF  INFORMATION. Par has had an  opportunity  to ask
questions and receive answers from Abrika  regarding the terms and conditions of
the  issuance  and  sale of the  Securities  and the  business,  properties  and
financial condition of Abrika and to obtain any additional information requested
and has received and considered all  information  that it deems relevant to make
an informed decision to purchase the Securities.

               (h)  RESTRICTED  SECURITIES. Par understands  that the Securities
have not been registered under the Securities Act and,  notwithstanding anything
to the contrary  contained in the Amended  Partnership  Agreement,  Par will not
sell, offer to sell,  assign,  pledge,  hypothecate or otherwise transfer any of
the Securities unless (i) pursuant to an effective  registration statement under
the Securities Act, (ii) such holder provides Abrika with an opinion of counsel,

                                      -13-


in a  generally  acceptable  form,  to the  effect  that a sale,  assignment  or
transfer of the Securities may be made without registration under the Securities
Act and the  transferee  agrees to be bound by the terms and  conditions of this
Agreement,  (iii) such holder  provides  Abrika with evidence of compliance with
Rule 144 promulgated under the Securities Act ("RULE 144"), including reasonable
assurances  (in the form of seller and broker  representation  letters) that the
Securities  may be sold  pursuant to Rule 144,  or (iv)  pursuant to Rule 144(k)
promulgated under the Securities Act following the applicable holding period.

               (i)  LEGENDS. Par agrees that the certificates for the Securities
shall bear the following legend:

          "THE  SECURITIES   REPRESENTED  BY  THIS  CERTIFICATE  HAVE  NOT  BEEN
REGISTERED  UNDER  THE  SECURITIES  ACT OF  1933 OR WITH  ANY  STATE  SECURITIES
COMMISSION,  AND MAY NOT BE  TRANSFERRED  OR  DISPOSED  OF BY THE  HOLDER IN THE
ABSENCE OF A REGISTRATION  STATEMENT THAT IS EFFECTIVE  UNDER THE SECURITIES ACT
OF 1933 AND APPLICABLE STATE LAWS AND RULES, OR UNLESS  IMMEDIATELY PRIOR TO THE
TIME SET FOR TRANSFER,  SUCH TRANSFER MAY BE EFFECTED  WITHOUT  VIOLATION OF THE
SECURITIES ACT OF 1933 AND OTHER APPLICABLE STATE LAWS AND RULES."

          In  addition,  Par  agrees  that  Abrika  may place  appropriate  stop
transfer orders with its transfer agent in respect of such certificates in order
to implement the restrictions on transfer set forth in this Agreement.

               (j)  BROKERS.  No agent,  broker, firm or other Person  acting on
behalf of Par,  or under the  authority  of Par,  is or shall be  entitled  to a
brokerage commission,  finder's fee or similar payment in connection with any of
the transactions contemplated hereby from Abrika or Par.

          6.4  PROCEDURES FOR  INDEMNIFICATION;  DEFENSE. If any person entitled
to indemnification  hereunder (the "INDEMNITEE") receives notice of any claim or
the  commencement  of any suit,  action or proceeding  with respect to which the
other party is obligated to provide  indemnification (the "INDEMNIFYING  PARTY")
pursuant  to  Section  6.2  or  6.3  hereof,   the  Indemnitee  shall  give  the
Indemnifying  Party written notice  thereof  within a reasonable  period of time
following the  Indemnitee's  receipt of such notice.  Such notice shall describe
the  claim  in  reasonable   detail  and  indicate  the  amount   (estimated  if
appropriate) of the Losses that have been or may be sustained by the Indemnitee.
The failure to so provide such notice shall not affect the Indemnifying  Party's
obligations  hereunder,  unless such Party is materially  prejudiced as a result
thereof.  The  Indemnifying  Party may,  subject to the other provisions of this
Section 6.4, compromise or defend, at such Indemnifying  Party's own expense and

                                      -18-


by such Indemnifying Party's own counsel, any such matter involving the asserted
liability  of  the  Indemnitee  in  respect  of  a  third-party  claim.  If  the
Indemnifying Party shall elect to compromise or defend such asserted  liability,
it shall,  within  thirty  (30) days (or sooner,  if the nature of the  asserted
liability reasonably so requires),  notify the Indemnitee of its intention to do
so and the Indemnitee shall reasonably cooperate,  at the request and reasonable
expense of the  Indemnifying  Party,  in the compromise of, or defense  against,
such asserted  liability.  The Indemnifying Party shall not be released from any
obligation to indemnify the Indemnitee hereunder with respect to a claim without
the prior written consent of the Indemnitee, unless the Indemnifying Party shall
deliver to the  Indemnitee a duly executed  agreement  settling or  compromising
such claim with no monetary  liability to, or  injunctive  relief  against,  the
Indemnitee and a complete release of the Indemnitee with respect thereto,  which
agreement  shall not limit or impair the  Indemnitee's  ability  to conduct  its
business.  The Indemnifying Party shall have the right, except as provided below
in this Section 6.4, to conduct and control the defense of any third-party claim
made  for  which it has been  provided  notice  hereunder.  All  costs  and fees
incurred  with  respect  to any such  claim  shall be borne by the  Indemnifying
Party.  The Indemnitee may participate in, but not control,  at its own expense,
the defense or settlement of any such claim;  PROVIDED,  that if the  Indemnitee
and the  Indemnifying  Party  shall have  conflicting  claims or  defenses,  the
Indemnifying  Party shall not be entitled to control any such conflicting claims
or defenses and the Indemnitee  shall be entitled to appoint a separate  counsel
for such claims and defenses, at the cost and expense of the Indemnifying Party;
PROVIDED, FURTHER, that if the Indemnifying Party shall not assume and pursue in
a  timely  and  diligent  manner  the  defense  of any  third-party  claim,  the
Indemnifying  Party shall be deemed to have ceded  control of such claim and the
Indemnitee  shall be  entitled  to  appoint a  counsel  of its  choice  for such
defense,  at the cost and expense of the Indemnifying Party. If the Indemnifying
Party shall choose to defend any claim, the Indemnitee shall, subject to Section
7.2 hereof, make available to the Indemnifying Party any books, records or other
documents  within its control that are  reasonably  required  for, and otherwise
cooperate with the Indemnifying Party with respect to, such defense.

pertaining  to  any  lawsuits  or   governmental   investigation,   except  such
information  that is in the public domain (such  information not being deemed to
be  in  the  public  domain  merely  because  it is  embraced  by  more  general
information that is in the public domain), other than as a result of a breach of
any of the provisions hereof.

          7.3  REMEDIES  UPON BREACH.  Each of Abrika and Par  acknowledges  and
agrees  that:  (i) Par and  Abrika,  as the  case may be,  would be  irreparably
injured  in the event of a breach by the other  party of any of the  obligations
under Section 7.2 hereof;  (ii) monetary damages would not be an adequate remedy
for such  breach;  (iii) Par and Abrika,  as the case may be,  shall be entitled
(without  the need to post any bond) to  injunctive  relief,  in addition to any
other remedy that they may have,  in the event of any such breach;  and (iv) the
existence of any claim that one party may have against the other,  whether under
this Agreement, any other agreement contemplated hereby or otherwise,  shall not
be a defense to (or reason for the delay of) the  enforcement  by Par or Abrika,
as applicable, of any of its rights or remedies under this Agreement.

          7.4  USE OF PROCEEDS.  Abrika shall use the net proceeds from the sale
of  Partnership  Interest  and the Note for working  capital  and other  general
business  purposes  (but  specifically  not  for  (i) any  distribution  to,  or
redemption  of, the holders of any  partnership  or other  equity  interests  of
Abrika  or  (ii)  any  payments   (including  loan  repayments,   but  excluding
compensation) to any Affiliates, Associates or partners of Abrika.

          7.5  CONSENTS. From the date hereof until the consummation of the IPO,
Abrika shall not, without the prior written consent of Par:

                                      -20-


                    (i)   authorize, create or issue any partnership interest or
equity  securities  senior  to the  Partnership  Interest  (or  any  partnership
interests issued upon conversion of the Note) or any bonds, debentures, notes or
other obligations or securities  convertible into or exchangeable for, or having
rights to purchase,  any partnership interest or equity securities senior to the
Partnership  Interest or any partnership  interests  issuable upon conversion of
the Note (each,  a "SENIOR EQUITY  ISSUANCE");  PROVIDED,  HOWEVER,  that Abrika
shall be permitted to effect a Senior  Equity  Issuance  without such consent if
(x) Par is given an opportunity to fully exercise  preemptive  rights in respect
thereof and (y) such  transaction  is with (1) a Person that is not an Affiliate
or partner (or  Affiliate  thereof) of Abrika or (2) an Affiliate or partner (or
Affiliate  thereof)  of Abrika,  and the terms of such  transaction  are no less
favorable  to  Abrika  than  terms  that  could  be  obtained  by  Abrika  in an
arms'-length  transaction,  PROVIDED,  that any  determination of an independent
appraiser or investment  banking firm shall be deemed conclusive with respect to
the terms of any transaction;

                    (ii)  convert its partnership  form into a corporation  form
(unless (A) such conversion is effected in connection with the completion of the
IPO or (B) (1)  such  conversion  shall  occur  in  connection  with  an  equity
financing with an  unaffiliated  third party and (2) Abrika shall have taken all
actions  necessary to preserve the contract  rights and  privileges  held at the
time of such  conversion  by Par  (E.G.,  liquidation  preference,  consent  and
preemptive rights)); or

                    (iii) enter into any arrangement,  agreement or transaction,
(other  than a Senior  Equity  Issuance  in which Par is  entitled  to  exercise
preemptive  rights),  with any  Affiliate or partner (or  Affiliate  thereof) of
Abrika,  including  any  loan to or from  any  such  Affiliate  or  partner  (or
Affiliate  thereof) of Abrika,  any sale or transfer  to any such  Affiliate  or
partner (or Affiliate  thereof) of Abrika,  of all or  substantially  all of the
assets of Abrika or any other  acquisition  of Abrika by any such person whether
effected by a merger,  consolidation securities exchange or similar transaction,
on terms that are less  favorable to Abrika than terms that could be obtained by
Abrika in an arms'-length  transaction;  PROVIDED, Abrika shall give Par written
notice of any material  transaction  with any Affiliate or partner (or Affiliate
thereof));  and PROVIDED,  FURTHER,  that any  determination  of an  independent
appraiser or investment  banking firm shall be deemed conclusive with respect to
the terms of any transaction.

                    Notwithstanding the foregoing, Par's consent shall no longer
be  required to take the  actions  listed in this  Section 7.5 if Par holds less
than the Equity Position Threshold.

                    In the  event  of any  conflict  between  the  terms of this
Section 7.5 and any provision of the Amended Partnership Agreement, this Section
7.5 shall govern.

PROVIDED,  that,  at the time such  notice is given,  a material  breach of this
Agreement by such  terminating  party shall not be the principal  reason for the
failure of the Closing to occur;

               (c)  By Par,  by written  notice to  Abrika,  if there has been a
