         "a. Death. In the event that,  during the term of this  Agreement,  the
Executive dies,  this Agreement and the Executive's  employment with the Company
shall automatically  terminate and the Company shall have no further obligations
or liability to the  Executive or his heirs,  administrators  or executors  with
respect  to  compensation  and  benefits  accruing  thereafter,  except  for the
obligation to pay the Executive's heirs,  administrators or executors any earned
but unpaid base salary,  unpaid pro rata annual bonus and unused  vacation  days
accrued through the date of death.  The Company shall deduct,  from all payments
made hereunder,  all applicable taxes,  including income tax, FICA and FUTA, and
other appropriate deductions.

         b.  Disability.  In the event that,  during the term of this Agreement,
the Executive shall be prevented from performing his duties and responsibilities
hereunder to the full extent required by the Company by reason of  "Disability,"
as defined hereinbelow,  this Agreement and the Executive's  employment with the
Company  shall  automatically  terminate  and the Company  shall have no further
obligations  or  liability  to the  Executive  or his heirs,  administrators  or
executors with respect to compensation and benefits accruing thereafter,  except
for the obligation to pay the Executive's heirs, administrators or executors any
earned but unpaid base salary,  unpaid pro rata annual bonus and unused vacation
days accrued through the date of Disability.  The Company shall deduct, from all
payments made hereunder,  all applicable  taxes,  including income tax, FICA and
FUTA, and other appropriate  deductions through the last date of the Executive's
employment with the Company. For purposes of this Agreement,  "Disability" shall
mean a physical  or mental  disability  that  prevents  the  performance  by the
Executive,  with  or  without  reasonable  accommodation,   of  his  duties  and
responsibilities  hereunder  for a  continuous  period  of not  less  than  four
consecutive  months,  or not less than an  aggregate  of four months  during any
one-year period.

         c. "Cause."

                  (i) At any time during the term of this Agreement, the Company
may  terminate  this  Agreement  and the  Executive's  employment  hereunder for
"Cause." For purposes of this Agreement, "Cause" shall mean: (a) the willful and
continued  failure  of the  Executive  to perform  substantially  his duties and
responsibilities  for the Company (other than any such failure  resulting from a
Disability)  after a written demand for substantial  performance is delivered to
the Executive by the Company, which specifically  identifies the manner in which
the Company  believes  that the Executive  has not  substantially  performed his
duties and responsibilities, which willful and continued failure is not cured by
the Executive within thirty (30) days of his receipt of said written demand; (b)
the conviction  of, or plea of guilty or nolo contendre to, a felony,  after the
exhaustion  of  all  available  appeals;  or (c)  the  willful  engaging  by the
Executive in gross misconduct which is materially and demonstratively  injurious
to the Company, after a written demand to cease or cure such gross misconduct is
delivered to the Executive by the Company,  which  specifically  identifies  the
manner in which the Company  believes that the  Executive  has  committed  gross
misconduct  that is  materially  and  demonstratively  injurious to the Company,
which gross  misconduct  does not cease or is not cured by the Executive  within
thirty (30) days of his receipt of said written demand.

                  (ii)  Termination  of the  Executive  for "Cause"  pursuant to
paragraphs  11(c)(i)(a)  and (c) shall be made by delivery to the Executive of a
copy of the written  demand  referred to in paragraphs  11(c)(i)(a)  and (c), or


                                       2
<PAGE>

pursuant to paragraphs  11(c)(i)(b) by a written  notice,  either of which shall
specify the basis of such  termination and the  particulars  thereof and finding
that in the  reasonable  judgment  of the  Company,  the  conduct  set  forth in
paragraph 11(c)(i)(a),  11(c)(i)(b) or 11(c)(i)(c),  as applicable, has occurred
and that such occurrence warrants the Executive's termination.

                  (iii) Upon  termination  of this  Agreement  for  "Cause," the
Company shall have no further  obligations  or liability to the Executive or his
heirs,  administrators  or executors with respect to  compensation  and benefits
thereafter, except for the obligation to pay the Executive any earned but unpaid
base  salary,  unpaid pro rata annual  bonus and unused  vacation  days  accrued
through the  Executive's  last day of employment  with the Company.  The Company
shall deduct, from all payments made hereunder,  all applicable taxes, including
income tax, FICA and FUTA, and other appropriate deductions.

         d.       "Good Reason."

                  (i) At any time during the term of this Agreement,  subject to
the conditions set forth in paragraph 11(d)(iii) hereinbelow,  the Executive may
terminate this  Agreement and the  Executive's  employment  with the Company for
"Good  Reason." For purposes of this  Agreement,  "Good  Reason"  shall mean the
occurrence, without the Executive's consent, of any of the following events: (a)
the assignment to the Executive of duties that are significantly different from,
and that result in a  substantial  diminution  of, the duties that he assumed on
the  Inception  Date;  (b) the  assignment  to the  Executive of a title that is
different  from  and   subordinate  to  the  title   specified  in  paragraph  2
hereinabove,  or (c) a Change of  Control  (as  defined in  paragraph  11(d)(ii)
hereinbelow).

                  (ii) For purposes of this Agreement, "Change of Control" means
the Company's  Board votes to approve:  (a) any  consolidation  or merger of the
Company pursuant to which fifty percent (50%) or less of the outstanding  voting
securities of the surviving or resulting  company are not owned  collectively by
the common share and warrant holders of Sino-Sult  Canada  (S.S.C.)  Limited and
Red Coral Group  Limited,  Inc. as of  September 1, 2004 (the  "Current  Control
Group"); (b) any sale, lease,  exchange or other transfer (in one transaction or
a series of related transactions) of all, or substantially all, of the assets of
the  Company  other than any sale,  lease,  exchange  or other  transfer  to any
company  where the  Company  owns,  directly or  indirectly,  100 percent of the
outstanding  voting securities of such company after any such transfer;  (c) any
person or persons (as such term is used in Section  13(d) of the Exchange Act of
1934, as amended), other than the Current Control Group, shall acquire or become
the  beneficial  owner (within the meaning of Rule 13d-3 under the Exchange Act)
whether directly,  indirectly,  beneficially or of record, of 50 percent or more
of outstanding  voting  securities of the Company;  or (d)  commencement  by any
entity,  person,  or group  (including  any  affiliate  thereof,  other than the
Company) of a tender  offer or exchange  offer where the offeree  acquires  more
than 50 percent of the then outstanding voting securities of the Company.

                  (iii) The  Executive  shall not be entitled to  terminate  his
employment  with the Company and this  Agreement  for "Good  Reason"  unless and
until  (a) he  shall  have  received  written  notice  from the  Company  of the
occurrence  of an event  constituting  "Good  Reason" as that term is defined in


                                       3
<PAGE>

paragraph 11(d)(i) and (ii) hereinabove,  which written notice the Company shall
deliver to the Executive  within five (5) business days of the occurrence of any
such event;  (b) he shall have  delivered  written  notice to the Company of his
intention to terminate  this  Agreement or his  employment  with the Company for
"Good Reason,"  which notice  specifies in reasonable  detail the  circumstances
claimed to provide the basis for such  termination  for "Good Reason," within 30
days of his  receipt  from  the  Company  of the  written  notice  described  in
paragraph  11(d)(iii)(a)  hereinabove,  the  Executive's  having obtained actual
knowledge of a "Good Reason;" and (c) the Company shall not have  eliminated the
circumstances  constituting "Good Reason" within 30 days of its receipt from the
Executive  of  the  written   notice   described   in  paragraph   11(d)(iii)(b)
hereinabove."

                  (iv) In the event that the Executive terminates this Agreement
and his employment  with the Company for "Good Reason," the Company shall pay or
provide to the Executive (or,  following his death,  to the  Executive's  heirs,
administrators or executors):  (a) any earned but unpaid base salary, unpaid pro
rata annual bonus and unused vacation days accrued through the Executive's  last
day of  employment  with the  Company;  (b) the  Executive's  full  base  salary
(including  guaranteed annual ten percent (10%) increases) through the Scheduled
Termination Date; (c) the Executive's guaranteed annual bonuses in the amount of
US$50,000.00  that he would have been awarded through the Scheduled  Termination
Date;  (d) the value of  vacation  days that the  Executive  would have  accrued
through the Scheduled Termination Date; (e) continued coverage, at the Company's
expense,  under all  Benefits  Plans in which the  Executive  was a  participant
immediately  prior to his last date of employment  with the Company,  or, in the
event  that any such  Benefit  Plans do not  permit  coverage  of the  Executive
following his last date of employment with the Company, under benefit plans that
provide  no less  coverage  than  such  Benefit  Plans,  through  the  Scheduled
Termination Date ("Continued Benefits"); and (f) severance in an amount equal to
the sum of the Executive's annual base salary in effect immediately prior to his
last date of employment  with the Company.  The Company  shall deduct,  from all
payments made hereunder,  all applicable  taxes,  including income tax, FICA and
FUTA, and other appropriate deductions.

                  (v) The Executive, at his option, shall be entitled to receive
the amounts  described in paragraphs  11(d)(iv)(b) and (c) hereinabove in a lump
sum within forty-five (45) days of his last date of employment with the Company.
To exercise  such option,  the Executive  shall  deliver to the Company  written
notice therefore within ten (10) business days after his last date of employment
with the Company.  If the Executive  fails to deliver such written notice within
ten (10) business days after his last date of employment  with the Company,  the
amounts  described in paragraphs  11(d)(iv)(b) and (c) hereinabove shall be paid
to the  Executive in the same manner as they would have been paid, in accordance
with the  provisions  of  paragraphs  6(a) and (b), had the  Executive  remained
employed by the Company. The amount described in paragraph 11(d)(iv)(f) shall be
paid to the Executive  within  forty-five (45) days of the Executive's last date

except that Continued Benefits shall be canceled or reduced to the extent of any
comparable  benefit coverage offered to the Executive during the period prior to
the  Scheduled  Termination  Date by a  subsequent  employer or other  person or
entity for which the Executive performs  services,  including but not limited to
consulting services.
