         2.1 Purchase and Sale; Purchase Price.

                  (a) Subject to the terms and conditions set forth herein,  the
Target  Company shall issue and sell and Seaside shall  purchase  eleven million

Stock").

immediately preceding September 30, 2004, whichever is less.

                  (c) The Total  Purchase Price shall be paid by delivery to the

         3.1  Representations,  Warranties and Agreements of the Target Company.
The Target Company hereby makes the following  representations and warranties to
Seaside, all of which shall survive the Closing:

                  (a)  Organization and  Qualification.  The Target Company is a
corporation, duly incorporated,  validly existing and in good standing under the
laws of the  jurisdiction of its formation,  with the requisite  corporate power
and  authority  to own and use its  properties  and  assets  and to carry on its
business as currently  conducted.  The Target Company has no subsidiaries  other
than  as set  forth  on  SCHEDULE  3.1(A)  attached  hereto  (collectively,  the
"Subsidiaries").  Each of the Subsidiaries is a corporation,  duly incorporated,
validly  existing and in good standing under the laws of the jurisdiction of its
incorporation,  with the full  corporate  power and authority to own and use its
properties and assets and to carry on its business as currently conducted.  Each
of the Target Company and the  Subsidiaries is duly qualified to do business and
is in good standing as a foreign  corporation in each  jurisdiction in which the
nature  of  the  business   conducted  or  property   owned  by  it  makes  such
qualification necessary,  except where the failure to be so qualified or in good
standing, as the case may be, would not, individually or in the aggregate,  have
a material adverse effect on the results of operations,  assets,  prospects,  or
financial condition of the Target Company and the Subsidiaries, taken as a whole
(a "Material Adverse Effect").

                  (b)  Authorization,  Enforcement.  The Target  Company has the
requisite  corporate  power and  authority to enter into and to  consummate  the
transactions  contemplated hereby and by each other Transaction  Document and to
otherwise to carry out its obligations  hereunder and thereunder.  The execution
and delivery of this  Agreement and each of the other  Transaction  Documents by
the Target Company and the consummation by it of the  transactions  contemplated
hereby and thereby has been duly authorized by all necessary  action on the part
of the Target Company.  Each of this Agreement and each of the other Transaction
Documents  has been or will be duly  executed  by the  Target  Company  and when
delivered in  accordance  with the terms hereof or thereof will  constitute  the
valid and  binding  obligation  of the Target  Company  enforceable  against the
Target Company in accordance with its terms,  except as such  enforceability may
be limited by applicable  bankruptcy,  insolvency,  reorganization,  moratorium,
liquidation or similar laws relating to, or affecting  generally the enforcement
of, creditors'  rights and remedies or by other equitable  principles of general
application.

                  (c)  Capitalization.  The  authorized,  issued and outstanding
capital  stock of the  Company  is set forth on  SCHEDULE  3.1(C).  No shares of
Common Stock are entitled to preemptive or similar rights,  nor is any holder of
the Common Stock  entitled to  preemptive or similar  rights  arising out of any
agreement or understanding  with the Target Company by virtue of this Agreement.
Except as  disclosed  in  SCHEDULE  3.1(C),  there are no  outstanding  options,
warrants,  script,  rights  to  subscribe  to,  registration  rights,  calls  or
commitments  of any  character  whatsoever  relating  to  securities,  rights or
obligations convertible into or exchangeable for, or giving any person any right
to  subscribe  for or  acquire,  any  shares  of  Common  Stock,  or  contracts,


                                       6
<PAGE>

commitments,  understandings, or arrangements by which the Target Company or any
Subsidiary is or may become bound to issue additional shares of Common Stock, or
securities or rights  convertible or  exchangeable  into shares of Common Stock.
Neither the Target  Company nor any  Subsidiary  is in  violation  of any of the
provisions  of  its  Certificate  of  Incorporation,  bylaws  or  other  charter
documents.

                  (d) Issuance of Securities.  The shares of Consideration Stock
have been duly and validly  authorized for issuance,  offer and sale pursuant to
this  Agreement  and,  when issued and delivered as provided  hereunder  against
payment  in  accordance  with the  terms  hereof,  shall be  valid  and  binding
obligations  of  the  Target  Company   enforceable  in  accordance  with  their
respective terms.

                  (e) No Conflicts.  The execution,  delivery and performance of
this Agreement and the other Transaction Documents by the Target Company and the
consummation by the Target Company of the transactions  contemplated  hereby and
thereby do not and will not (i)  conflict  with or violate any  provision of its
Certificate of Incorporation or bylaws (each as amended through the date hereof)
or (ii) be subject to obtaining any consents except those referred to in Section
3.1(f), conflict with, or constitute a default (or an event which with notice or

rights  of  termination,   amendment,   acceleration  or  cancellation  of,  any
agreement,  indenture or instrument to which the Target  Company is a party,  or
(iii)  result in a violation  of any law,  rule,  regulation,  order,  judgment,
injunction,  decree or other restriction of any court or governmental  authority

and regulations), or by which any property or asset of the Target Company or its
Subsidiaries  is bound or  affected,  except  in the case of clause  (ii),  such
conflicts, defaults, terminations, amendments, accelerations,  cancellations and
violations  as would  not,  individually  or in the  aggregate,  have a Material
Adverse Effect.  The business of the Target Company and its  Subsidiaries is not
being  conducted  in  violation  of any  law,  ordinance  or  regulation  of any
governmental authority.

                  (f) Consents and Approvals.  Except as specifically  set forth

challenges the legality,  validity or  enforceability  of any of the Transaction


                                       7
<PAGE>

Documents or the shares of Consideration  Stock, (ii) could,  individually or in
the aggregate, have a Material Adverse Effect or (iii) could, individually or in

                  (h) No Default or  Violation.  Except as set forth in SCHEDULE
3.1(H)  hereto,  neither the Target Company nor any Subsidiary (i) is in default
under or in violation of any  indenture,  loan or credit  agreement or any other
agreement  or  instrument  to  which  it is a party or by which it or any of its
properties is bound, except such conflicts or defaults as do not have a Material
Adverse  Effect,  (ii) is in violation of any order of any court,  arbitrator or
governmental  body, except for such violations as do not have a Material Adverse
Effect,  or (iii) is in  violation  of any statute,  rule or  regulation  of any
governmental  authority  which  could  (individually  or in the  aggregate)  (a)
adversely affect the legality, validity or enforceability of this Agreement, (b)
have a Material  Adverse  Effect or (c)  adversely  impair the Target  Company's
ability or obligation to perform fully on a timely basis its  obligations  under
this Agreement.

                  (i)  Disclosure   Documents.   The  Disclosure  Documents  are
accurate in all  material  respects  and do not contain any untrue  statement of
material fact or omit to state any material fact  necessary in order to make the
statements  made therein,  in light of the  circumstances  under which they were
made, not misleading.

                  (j)  Non-Registered  Offering.  Neither the Target Company nor
any Person  acting on its  behalf has taken or will take any action  (including,
without  limitation,  any offering of any securities of the Target Company under
circumstances  which would  require the  integration  of such  offering with the
offering  of the  Consideration  Stock  under the  Securities  Act) which  might
subject  the  offering,  issuance  or sale  of the  Consideration  Stock  to the
registration requirements of Section 5 of the Securities Act.

                  (k) Placing Agent.  The Target Company accepts and agrees that
Dungarvon  Associates,  Inc.  ("Dungarvon")  is acting for  Seaside and does not
regard  any person  other  than  Seaside as its  customer  in  relation  to this
Agreement, and that it has not made any recommendation to the Target Company, in
relation to this Agreement and is not advising the Target  Company,  with regard
to the  suitability or merits of the Seaside Shares and in particular  Dungarvon
has no duties or  responsibilities  to the Target Company for the best execution
of the transaction contemplated by this Agreement.

                  (l) Private Placement Representations.  The Target Company (i)
has received and carefully reviewed such information and documentation  relating
to Seaside that the Target Company has requested, including, without limitation,
Seaside's  Confidential  Private Offering  Memorandum,  dated June 14, 2004 (the
"Private Placement  Memorandum");  (ii) has had a reasonable  opportunity to ask
questions of and receive answers from Seaside concerning the Seaside Shares, and
all such questions,  if any, have been answered to the full  satisfaction of the
Target Company; (iii) has such knowledge and expertise in financial and business
matters  that it is capable of  evaluating  the merits and risks  involved in an
investment in the Seaside Shares;  (iii) understands that Seaside has determined
that the  exemption  from the  registration  provisions of the  Securities  Act,
provided by Section 4(2) of the  Securities  Act is  applicable to the offer and
sale of the Seaside Shares, based, in part, upon the representations, warranties


                                       8
<PAGE>

and agreements  made by the Target Company  herein;  and (iv) except as provided
herein and in the Private Placement Memorandum, no representations or warranties
have been made to the  Target  Company by  Seaside  or any  agent,  employee  or
affiliate of Seaside and in entering into this transaction the Target Company is
not  relying  upon any  information,  other  than  the  results  of  independent
investigation by the Target Company.

Seaside  acknowledges and agrees that the Target Company makes no representation
or warranty  with  respect to the  transactions  contemplated  hereby other than
those specifically set forth in Section 3.1 hereof.

         3.2 Representations and Warranties of Seaside. Seaside hereby makes the
following  representations  and warranties to the Target  Company,  all of which
shall survive the Closing:

                  (a) Organization;  Authority.  Seaside is a corporation,  duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction  of its formation  with the requisite  power and authority to enter
into and to consummate  the  transactions  contemplated  hereby and by the other
Transaction  Documents and otherwise to carry out its obligations  hereunder and
thereunder. The acquisition of the shares of Consideration Stock to be purchased
by Seaside  hereunder has been duly  authorized  by all necessary  action on the
part of Seaside.  This Agreement has been duly executed and delivered by Seaside
and constitutes the valid and legally binding obligation of Seaside, enforceable
against it in accordance with its terms,  except as such  enforceability  may be
limited by  applicable  bankruptcy,  insolvency,  reorganization,  moratorium or
similar laws relating to, or affecting  generally the enforcement of,  creditors
rights and remedies or by other general principles of equity.

                  (b)  Investment  Intent.  Seaside is  acquiring  the shares of
Consideration  Stock to be  purchased by it  hereunder,  for its own account for
investment purposes only and not with a view to or for distributing or reselling
such shares of  Consideration  Stock,  or any part thereof or interest  therein,
without  prejudice,  however,  to Seaside's right,  subject to the provisions of
this Agreement,  at all times to sell or otherwise dispose of all or any part of
such shares of  Consideration  Stock in compliance with  applicable  federal and
state securities laws.

                  (c) Experience of Seaside.  Seaside,  either alone or together
with its representatives,  has such knowledge,  sophistication and experience in
business and financial  matters so as to be capable of evaluating the merits and
risks of an investment in the shares of Consideration Stock to be acquired by it
hereunder, and has so evaluated the merits and risks of such investment.

                  (d) Ability of Seaside to Bear Risk of Investment.  Seaside is
able to bear the economic risk of an investment in the Consideration Stock to be
acquired by it hereunder  and, at the present time, is able to afford a complete
loss of such investment.

                  (e) Access to Information.  Seaside  acknowledges  that it has
been  afforded  (i) the  opportunity  to ask  such  questions  as it has  deemed
necessary of, and to receive answers from, representatives of the Target Company
concerning the terms and conditions of the Consideration Stock offered hereunder


                                       9
<PAGE>

and the  merits  and  risks of  investing  in such  securities;  (ii)  access to
information  about  the  Target  Company  and  the  Target  Company's  financial
condition, results of operations, business, properties, management and prospects
sufficient to enable it to evaluate its investment in the  Consideration  Stock;
and (iii) the opportunity to obtain such additional information which the Target
Company possesses or can acquire without  unreasonable effort or expense that is
necessary to make an informed investment decision with respect to the investment
and to verify the  accuracy  and  completeness  of the  information  that it has
received about the Target Company.

                  (f) Reliance.  Seaside  understands and acknowledges  that (i)
the shares of  Consideration  Stock being  offered and sold to it hereunder  are
being  offered  and sold  without  registration  under the  Securities  Act in a
private  placement  that is  exempt  from  the  registration  provisions  of the
Securities   Act  under  Section  4(2)  of  the  Securities  Act  and  (ii)  the
availability  of such exemption  depends in part on, and that the Target Company
will rely upon the accuracy and truthfulness  of, the foregoing  representations
and Seaside hereby consents to such reliance.

                  (g) Regulation S. Seaside  understands and  acknowledges  that
(A) the  shares  of  Consideration  Stock  have not been  registered  under  the
Securities  Act, are being sold in reliance upon an exemption from  registration
afforded by Regulation S; and that such shares of  Consideration  Stock have not
been registered with any state securities commission or authority;  (B) pursuant
to the requirements of Regulation S, the shares of  Consideration  Stock may not
be  transferred,  sold or  otherwise  exchanged  unless in  compliance  with the
provisions of Regulation S and/or pursuant to registration  under the Securities
Act, or pursuant to an available exemption hereunder; and (C) the Target Company
is under no obligation to register the shares of  Consideration  Stock under the
Securities  Act or any state  securities  law, or to take any action to make any
exemption from any such registration provisions available.

         Seaside  is  not a U.S.  Person  and is not  acquiring  the  shares  of
Consideration  Stock for the  account of any U.S.  Person;  (B) no  director  or
executive officer of Seaside is a national or citizen of the United States;  and
(C) it is not  otherwise  deemed to be a "U.S.  Person"  within  the  meaning of
Regulation S.

         Seaside was not formed  specifically  for the purpose of acquiring  the
shares of Consideration Stock purchased pursuant to this Agreement.

         Seaside is  purchasing  the shares of  Consideration  Stock for its own
account and risk and not for the account or benefit of a U.S.  Person as defined
in Regulation S and no other person has any interest in or  participation in the
shares of Consideration Stock or any right, option, security interest, pledge or
other interest in or to the shares of Consideration  Stock. Seaside understands,
acknowledges and agrees that it must bear the economic risk of its investment in
the  shares of  Consideration  Stock for an  indefinite  period of time and that
prior to any such offer or sale, the Target Company may require,  as a condition
to  effecting a transfer  of the shares of  Consideration  Stock,  an opinion of
counsel,  acceptable to the Target Company,  as to the registration or exemption
therefrom under the Securities Act and any state securities acts, if applicable.


                                       10
<PAGE>

         Seaside will,  after the  expiration of the Restricted  Period,  as set
forth  under  Regulation  S  Rule  903(b)(3)(iii)(A),  offer,  sell,  pledge  or
otherwise  transfer the shares of  Consideration  Stock only in accordance  with
Regulation S, or pursuant to an available  exemption  under the  Securities  Act
and, in any case, in accordance  with  applicable  state  securities  laws.  The
transactions  contemplated by this Agreement have neither been pre-arranged with
a purchaser who is in the U.S. or who is a U.S.  Person,  nor are they part of a
plan or scheme to evade the registration provisions of the United States federal
securities laws.

         The offer leading to the sale evidenced hereby was made in an "offshore
transaction."  For  purposes  of  Regulation  S,  Seaside  understands  that  an
"offshore  transaction"  as defined under  Regulation S is any offer or sale not
made to a person in the  United  States and either (A) at the time the buy order
is originated,  the purchaser is outside the United States, or the seller or any
person  acting on his behalf  reasonably  believes that the purchaser is outside
the United  States;  or (B) for  purposes of (1) Rule 903 of  Regulation  S, the
transaction  is  executed  in, or on or through a physical  trading  floor of an
established  foreign  exchange that is located  outside the United States or (2)
Rule 904 of  Regulation  S, the  transaction  is executed  in, on or through the
facilities of a designated  offshore  securities  market, and neither the seller
nor any  person  acting  on its  behalf  knows  that  the  transaction  has been
prearranged with a buyer in the U.S.

         Neither  Seaside nor any  Affiliate  or any Person  acting on Seaside's
behalf,  has made or is aware of any  "directed  selling  efforts" in the United
States,  which is defined in Regulation S to be any activity  undertaken for the
purpose  of,  or that  could  reasonably  be  expected  to have the  effect  of,
conditioning  the  market  in  the  United  States  for  any of  the  shares  of
Consideration Stock being purchased hereby.

         Seaside understands that the Target Company is the seller of the shares
of  Consideration  Stock which are the subject of this Agreement,  and that, for
purpose of Regulation S, a  "distributor"  is any  underwriter,  dealer or other
person  who  participates,   pursuant  to  a  contractual  arrangement,  in  the
distribution of securities  offered or sold in reliance on Regulation S and that
an  "affiliate"  is any  partner,  officer,  director or any person  directly or
indirectly controlling, controlled by or under common control with any person in
question. Seaside agrees that Seaside will not, during the Restricted Period set
forth under Rule 903(b)(iii)(A), act as a distributor, either directly or though
any affiliate, nor shall it sell, transfer,  hypothecate or otherwise convey the
shares of Consideration Stock other than to a non-U.S. Person.

         Seaside acknowledges that the shares of Consideration Stock will bear a
legend in substantially the following form:


THE SHARES  REPRESENTED  BY THIS  CERTIFICATE  HAVE BEEN  OFFERED AND SOLD IN AN
"OFFSHORE  TRANSACTION"  IN RELIANCE  UPON  REGULATION S AS  PROMULGATED  BY THE
SECURITIES AND EXCHANGE COMMISSION.  ACCORDINGLY,  THE SECURITIES REPRESENTED BY
THIS  CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE
"SECURITIES  ACT") AND MAY NOT BE  TRANSFERRED  OTHER  THAN IN  ACCORDANCE  WITH
REGULATION S, PURSUANT TO REGISTRATION  UNDER THE SECURITIES ACT, OR PURSUANT TO


                                       11
<PAGE>

AN  AVAILABLE   EXEMPTION  FROM  REGISTRATION  UNDER  THE  SECURITIES  ACT,  THE
AVAILABILITY  OF WHICH IS TO BE ESTABLISHED TO THE  SATISFACTION OF THE COMPANY.
THE SECURITIES  REPRESENTED BY THIS CERTIFICATE CANNOT BE THE SUBJECT OF HEDGING
TRANSACTIONS  UNLESS SUCH  TRANSACTIONS  ARE  CONDUCTED IN  COMPLIANCE  WITH THE
SECURITIES ACT.

THE SALE OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS RESTRICTED PURSUANT TO
THE TERMS OF A STOCK  PURCHASE  AGREEMENT,  DATED  OCTOBER 5, 2004,  BETWEEN THE

The Target Company acknowledges and agrees that Seaside makes no representations
or warranties with respect to the  transactions  contemplated  hereby other than
those specifically set forth in this Section 3.2.

                                   ARTICLE IV

exemption from qualification of the shares of Consideration  Stock, for offering
or sale in any  jurisdiction,  or the  initiation  of any  proceeding  for  such

any event that makes any statement of a material fact made by the Target Company

order to make the statements  therein,  in the light of the circumstances  under
which they are made,  not  misleading,  (ii) use its best efforts to prevent the

Sky  laws,  and (iii) if at any time any state  securities  commission  or other
regulatory  authority  shall  issue an order  suspending  the  qualification  or
exemption from qualification of the Consideration Stock under any such laws, and
use its best  efforts to obtain the  withdrawal  or lifting of such order at the
earliest possible time.

         4.3 Blue Sky Laws.  The Target  Company agrees that it will execute all

<PAGE>

         4.4  Integration.  The Target  Company shall not and shall use its best
efforts to ensure that no Affiliate shall sell, offer for sale or solicit offers
to buy or otherwise  negotiate in respect of any security (as defined in Section
2 of the Securities  Act) that would be integrated with the offer or sale of the
shares of  Consideration  Stock in a manner that would require the  registration
under the  Securities  Act of the sale of the shares of  Consideration  Stock to
Seaside.

         4.5 Furnishing of Rule 144(c) Materials.  The Target Company shall, for
so long as any of the  Consideration  Stock  remain  outstanding  and during any
period in which the Target  Company is not subject to Section 13 or 15(d) of the
Exchange Act, make available to any registered holder of the Consideration Stock
in  connection  with any sale  thereof  and any  prospective  purchaser  of such
Consideration  Stock from such Person,  such information in accordance with Rule
144(c)  promulgated  under  the  Securities  Act  as is  required  to  sell  the
Consideration Stock under Rule 144 promulgated under the Securities Act.

         4.6 Solicitation Materials. The Target Company shall not (i) distribute
any offering materials in connection with the offering and sale of the shares of
Consideration  Stock other than the Disclosure  Documents and any amendments and
supplements thereto prepared in compliance herewith or (ii) solicit any offer to
buy or sell the  shares of  Consideration  Stock by means of any form of general
solicitation or advertising.

         Listing of Common Stock.  If the Common Stock is or shall become listed
on the OTCBB or on another  exchange,  the Target Company shall (a) use its best
efforts to maintain  the listing of its Common  Stock on the OTCBB or such other
exchange on which the Common  Stock is then listed until four (4) years from the
date  hereof,  and (b)  shall  provide  to  Seaside  evidence  of such  listing.
Notwithstanding  the foregoing,  the Target Company may voluntarily  cease to be
listed on the OTCBB at such time as the Target Company becomes listed on another
exchange.

         4.7

         4.8 Indemnification.

                  (a) Indemnification

                           (i)  The  Target   Company   shall,   notwithstanding
termination of this  Agreement and for a period of six (6) years,  indemnify and
hold  harmless  Seaside  and its  officers,  directors,  agents,  employees  and
Affiliates,  each Person who controls or Seaside  (within the meaning of Section
15 of the Securities Act or Section 20 of the Exchange Act) (each such Person, a
"Control Person") and the officers,  directors, agents, employees and Affiliates
of each such Control Person,  to the fullest extent permitted by applicable law,
from  and  against  any and all  losses,  claims,  damages,  liabilities,  costs
(including,  without  limitation,  costs of preparation and attorneys' fees) and
expenses (collectively,  "Losses"), as incurred, arising out of, or relating to,
a breach or breaches of any representation,  warranty,  covenant or agreement by
the Target Company under this Agreement or any other Transaction Document.

                           (ii) Seaside  shall,  notwithstanding  termination of
this  Agreement  and for a period of six (6) years,  indemnify and hold harmless
the Target Company, its officers,  directors, agents and employees, each Control
Person and the officers, directors, agents and employees of each Control Person,


                                       13
<PAGE>

to the fullest extent  permitted by applicable law, from and against any and all
Losses, as incurred, arising out of, or relating to, a breach or breaches of any
representation,  warranty, covenant or agreement by Seaside under this Agreement
or the other  Transaction  Documents,  except for Losses  solely  arising out of
negligence, bad faith or breach of this Agreement by the Target Company.

                           (iii) The Target Company and Seaside acknowledge that
in the SEC's  opinion,  directors,  officers and persons  controlling  a company
subject to the  Securities Act can not be indemnified  for  liabilities  arising
under the Securities Act by such company.


                  (b) Conduct of Indemnification  Proceedings. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity  hereunder
(an  "Indemnified  Party"),  such  Indemnified  Party  promptly shall notify the
Person from whom indemnity is sought (the "Indemnifying  Party") in writing, and
the  Indemnifying  Party  shall  assume  the  defense  thereof,   including  the
employment of counsel  reasonably  satisfactory to the Indemnified Party and the
payment of all fees and expenses  incurred in connection  with defense  thereof;
provided,  that the failure of any  Indemnified  Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this  Agreement,  except  (and  only) to the  extent  that it  shall be  finally
determined  by a court of competent  jurisdiction  (which  determination  is not
subject to appeal or further  review) that such failure  shall have  proximately
and materially adversely prejudiced the Indemnifying Party.

                  An Indemnified  Party shall have the right to employ  separate
counsel in any such  Proceeding and to participate in the defense  thereof,  but
the  fees  and  expenses  of  such  counsel  shall  be at the  expense  of  such
Indemnified  Party or Parties unless:  (1) the Indemnifying  Party has agreed to
pay such fees and  expenses;  or (2) the  Indemnifying  Party  shall have failed
promptly  to  assume  the  defense  of such  Proceeding  and to  employ  counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3)
the named  parties to any such  Proceeding  (including  any  impleaded  parties)
include  both  such  Indemnified  Party  and the  Indemnifying  Party,  and such
Indemnified Party shall have been advised by counsel that a conflict of interest
is likely to exist if the same counsel were to represent such Indemnified  Party
and the Indemnifying  Party (in which case, if such  Indemnified  Party notifies
the  Indemnifying  Party in writing that it elects to employ separate counsel at
the expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense of the claim against the Indemnified  Party but will
retain the right to control the overall Proceedings out of which the claim arose
and such counsel  employed by the  Indemnified  Party shall be at the expense of
the  Indemnifying  Party).  The  Indemnifying  Party shall not be liable for any
settlement of any such Proceeding  effected without its written  consent,  which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party,  unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.


                                       14
<PAGE>

                  All fees and  expenses of the  Indemnified  Party to which the
Indemnified Party is entitled hereunder (including  reasonable fees and expenses
to the extent incurred in connection with  investigating  or preparing to defend
such Proceeding in a manner not inconsistent with this Section) shall be paid to
the  Indemnified  Party,  as incurred,  within ten (10) Business Days of written
notice thereof to the Indemnifying Party.

                  No  right  of  indemnification  under  this  Section  shall be
available as to a particular Indemnified Party if the Indemnifying Party obtains
a non-appealable final judicial  determination that such Losses arise solely out
of the negligence, breach of agreement or bad faith of such Indemnified Party in
performing the obligations of such  Indemnified  Party under this Agreement or a
breach by such Indemnified Party of its obligations under this Agreement.

                  (c) Contribution.  If a claim for  indemnification  under this
Section is unavailable to an Indemnified  Party or is  insufficient to hold such
Indemnified Party harmless for any Losses in respect of which this Section would
apply  by its  terms  (other  than by  reason  of  exceptions  provided  in this
Section), 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 Losses in such  proportion as is  appropriate to reflect the
relative  benefits  received by the  Indemnifying  Party on the one hand and the
Indemnified Party on the other and the relative fault of the Indemnifying  Party
and Indemnified  Party in connection with the actions or omissions that resulted
in such  Losses  as well as any other  relevant  equitable  considerations.  The
relative  fault  of such  Indemnifying  Party  and  Indemnified  Party  shall be
determined  by reference  to, among other  things,  whether there was a judicial
determination  that such Losses arise in part out of the negligence or bad faith
of the Indemnified Party in performing the obligations of such Indemnified Party
under this Agreement or the Indemnified  Party's breach of its obligations under
this Agreement.  The amount paid or payable by a party as a result of any Losses
shall be deemed to include any attorneys' or other fees or expenses  incurred by
such party in connection with any Proceeding to the extent such party would have
been indemnified for such fees or expenses if the  indemnification  provided for
in this Section was available to such party.

                  (d) Non-Exclusivity. The indemnity and contribution agreements
contained in this Section are in addition to any  obligation  or liability  that
the Indemnifying Parties may have to the Indemnified Parties.

         4.9 Sale of Seaside  Consideration  Shares.  Seaside  shall  assist the
Target Company in setting up and  maintaining a trading  account at a registered
broker in the United Kingdom to facilitate the sale of the Seaside Consideration
Shares.  Broker's  commissions in the trading  account shall not exceed one half
percent (0.5%).

         4.10 Lock Up by Seaside. Seaside shall not sell, transfer or assign all
or any of the  shares  of  Consideration  Stock  for a  period  of one (1)  year
following the Closing,  without the written consent of the Target Company, which
consent may be withheld in the Target Company's sole discretion.


                                       15
<PAGE>

         4.11 Short Sales. Seaside agrees it will not enter into any Short Sales
(as  hereinafter  defined) until the date that Seaside no longer owns the shares
of Consideration  Stock. For purpose hereof, a "Short Sale" shall mean a sale of
Common  Stock by  Seaside  that is marked as a short  sale and that is made at a
time when there is no equivalent offsetting long position in the Common Stock by
Seaside.

         4.12  Liquidation  of  Consideration  Stock.  Commencing  on  the  date
occurring  one (1) year  after  the  Closing,  Seaside  may sell its  shares  of
Consideration Stock at a monthly rate no greater than an amount equal to fifteen
percent (15%) of the Target  Company's prior month's  trading volume,  provided,
however,  that  Seaside  may  execute  block  trades of 50,000 or more shares of
Consideration  Stock and such sales shall not count  toward the fifteen  percent
(15%) limitation on the rate of liquidation. Seaside shall use the proceeds from
these liquidations to re-purchase Seaside Shares in the marketplace.

         4.13 Definitive  Certificates.  The definitive  certificates evidencing
the shares of  Consideration  Stock shall be held at the office of the Secretary
of Seaside if and when the Consideration Stock is received from the Escrow Agent
pursuant to the Escrow  Agreement and shall remain with the Secretary  until one
(1) year from the date hereof.

         4.14  London  Stock  Exchange.   Seaside  shall  register  the  Seaside

         5.4 Amendments;  Waivers.  No provision of this Agreement may be waived
or amended except in a written  instrument  signed, in the case of an amendment,
by both the Target  Company  and  Seaside,  or, in the case of a waiver,  by the
party against whom  enforcement  of any such waiver is sought.  No waiver of any

Agreement shall be deemed to be a continuing waiver in the future or a waiver of
any other  provision,  condition or requirement  hereof,  nor shall any delay or
omission of either  party to exercise any right  hereunder in any manner  impair
the exercise of any such right accruing to it thereafter.

         5.5  Headings.  The headings  herein are for  convenience  only, do not
constitute a part of this  Agreement  and shall not be deemed to limit or affect
any of the provisions hereof.

         5.6  Successors and Assigns.  This Agreement  shall be binding upon and
inure  to the  benefit  of the  parties  and  their  respective  successors  and
permitted  assigns.  The  assignment by a party of this  Agreement or any rights
hereunder shall not affect the obligations of such party under this Agreement.

         5.7 No Third Party  Beneficiaries.  This  Agreement is intended for the
benefit of the parties  hereto and their  respective  permitted  successors  and
assigns and is not for the benefit of, nor may any provision  hereof be enforced
by, any other person.

         5.8  Governing  Law;  Venue;  Service of Process.  The  parties  hereto
acknowledge  that  the  transactions  contemplated  by  this  Agreement  and the
exhibits hereto bear a reasonable relation to the State of New York. The parties
hereto agree that the  internal  laws of the State of New York shall govern this
Agreement  and the exhibits  hereto,  including,  but not limited to, all issues
related to usury.  Any action to enforce the terms of this  Agreement  or any of
its exhibits,  or any other Transaction Document shall be brought exclusively in
the state and/or federal courts situated in the County and State of New York. If
and only if New York declines  jurisdiction  within the State of New York,  such
action  shall be  brought in the State and  County  where the  Target  Company's
principal  place of  business is  situated.  Service of process in any action by
Seaside or the Target Company to enforce the terms of this Agreement may be made
by  serving  a copy of the  summons  and  complaint,  in  addition  to any other
relevant  documents,  by commercial  overnight courier to the other party at its

         5.9 Survival.  The representations and warranties of the Target Company
and Seaside  contained in Article III and the  agreements  and  covenants of the
parties contained in Article IV and this Article V shall survive the Closing.

5.10  Counterpart  Signatures.  This  Agreement  may be  executed in two or more
counterparts,  all of which when taken  together shall be considered one and the
same agreement and shall become effective when  counterparts have been signed by
each party and  delivered  to the other  party,  it being  understood  that both
parties need not sign the same  counterpart.  In the event that any signature is
delivered by facsimile  transmission,  such  signature  shall create a valid and
binding  obligation of the party executing (or on whose behalf such signature is
executed) the same with the same force and effect as if such facsimile signature
page were an original thereof.

         5.11 Publicity.  The Target Company and Seaside shall consult with each
other in issuing any press releases or otherwise  making public  statements with
respect to the  transactions  contemplated  hereby and neither party shall issue
any such press release or otherwise make any such public  statement  without the
prior written  consent of the other,  which  consent  shall not be  unreasonably
withheld or delayed,  unless counsel for the disclosing  party deems such public
statement to be required by applicable  federal  and/or state  securities  laws.
Except as otherwise required by applicable law or regulation, the Target Company
will not disclose to any third party  (excluding its legal counsel,  accountants
and representatives) the name of Seaside.

         5.12  Severability.  In case any one or more of the  provisions of this
Agreement  shall be invalid or  unenforceable  in any respect,  the validity and
enforceability of the remaining terms and provisions of this Agreement shall not
in any way be affected or impaired thereby and the parties will attempt to agree
upon a valid and enforceable  provision  which shall be a reasonable  substitute
therefore,  and upon so agreeing, shall incorporate such substitute provision in
this Agreement.

         5.13  Limitation  of  Remedies.  With  respect  to claims by the Target
Company or any person acting by or through the Target Company,  or by Seaside or
any person acting through Seaside,  for remedies at law or at equity relating to
or arising out of a breach of this  Agreement,  liability,  if any, shall, in no
event,  include loss of profits or incidental,  indirect,  exemplary,  punitive,
special or consequential damages of any kind.
