in this  Agreement.  The Option  shall be  considered  a  Non-Qualified  Option.
Optionee acknowledges and agrees that this Option is not an Incentive Option and
that the Company is not  obligated to take any action or refrain from taking any
action in order to cause this Option to qualify as an Incentive Option.

         2. OPTION PRICE.  At any time when shares are to be purchased  pursuant
to the Option,  the purchase  price (the  "Option  Price") for each Option Share
shall be $0.50, subject to adjustment as provided in Section 8 below.

         3. EXERCISE PERIOD.

            (a)  20% of the Option is exercisable on the Date of Grant, and  20%
of the Option becomes  exercisable on each of August 10, 2006,  2007,  2008, and
2009.

            (b)  The period for exercise of the Option  shall  terminate at 5:00
p.m., New York, New York time on August 10, 2010 unless  terminated  earlier  as
provided in this Agreement.


                                       1



         4. EXERCISE OF OPTION.

            (a)  The  Option  may be exercised in whole or in part by delivering
to the  Secretary  of the  Company  (i) a Notice And  Agreement  Of  Exercise Of
Option,  substantially  in the form attached hereto as Exhibit A, specifying the
number of Option Shares with respect to which the Option is exercised,  and (ii)
full payment of the Option Price for such shares.  Payment in cash shall be made
by certified check or cleared funds.

            (b)  Promptly  upon  receipt of the Notice And Agreement Of Exercise
Of Option (a form of which is attached to this  Agreement as Exhibit A) together
with the full  payment of the Option  Price,  the Company  shall  deliver to the
Optionee a properly executed certificate or certificates representing the Option
Shares being purchased.

            (c)  During  the  lifetime  of  the  Optionee,  the  Option shall be
exercisable  only by the  Optionee;  provided,  that in the  event of the  legal
disability  of an  Optionee,  the  guardian  or personal  representative  of the
Optionee  may exercise  the Option if such  guardian or personal  representative
obtains a ruling from the Internal  Revenue  Service or an opinion of counsel to
the effect that neither the grant nor the exercise of such power is violative of
Section  422(b)(5),  or its  successor  provision,  of the Code.  Any opinion of
counsel  must be  acceptable  to the Option  Committee  both with respect to the
counsel rendering the opinion and with respect to the form of opinion. Following
the  death  of the  Optionee,  the  Option  may  be  exercised  by the  personal
representative of the Optionee during any remaining term of the Option.

            (d)  (1) If for any reason (other than the termination of Optionee's
employment  because  of  Optionee's  death  or  the  termination  of  Optionee's
employment by the Company for cause (as defined  below)) the Optionee  ceases to
be  employed  by the  Company,  then (i) any  Incentive  Option then held may be
exercised   within  three  (3)  months  after   termination  of  the  Optionee's
employment,  and (ii) any Non-Qualified  Option then held by the Optionee may be
exercised   within  three  (3)  months  after   termination  of  the  Optionee's
employment,  but,  in either  case,  only to the extent  that (A) the Option was
exercisable  according to its terms on the date of termination of the Optionee's
employment, and (B) the period for exercise of the Option, as defined in Section
3 of this  Agreement,  has not  terminated  as of the  date  of  exercise.  Upon
termination of the respective  periods set forth in the previous  sentence,  any
unexercised portion of an Option shall expire.

                 (2) If the Optionee's employment with the Company is terminated
because of the Optionee's  death,  any Option then held may be exercised  within
one (1) year after  termination,  but only to the extent that (A) the Option was
exercisable  according to its terms on the date of termination of the Optionee's
employment, and (B) the period for exercise of the Option, as defined in Section
3 of this Agreement, has not terminated as of the date of exercise.

                 (3) If the Optionee's employment by the  Company is  terminated
for cause, any Option held by the Optionee at the time Optionee's  employment is
terminated  shall expire upon delivery to the Optionee of notice of termination,
which may be oral or in writing,  and all rights to purchase  shares pursuant to
the  Option  shall  terminate  immediately.   As  used  in  this  Section  4(d),
termination  "for cause" means a discharge on account of dishonesty,  disloyalty
or  insubordination  on the  part of the  Optionee  as  determined  in the  sole
discretion  of the Board Of Directors of the  Corporation  or a Committee of the
Board Of Directors.

         5. WITHHOLDING  TAXES.  The  Company  may  take such  steps as it deems
necessary or appropriate  for the  withholding of any taxes which the Company is
required  by  any  law or  regulation  or any  governmental  authority,  whether
federal, state or local, domestic or foreign, to withhold in connection with the
Option  including,  but not limited to, the withholding of all or any portion of
any payment owed by the


                                       2



Company to the Optionee or the  withholding  of issuance of Option  Shares to be
issued upon the exercise of the Option.

         6. SECURITIES  LAWS  REQUIREMENTS.  No  Option  Shares  shall be issued
unless and until, in the opinion of the Company,  there has been full compliance
with any applicable registration  requirements of the Securities Act of 1933, as
amended (the "1933 Act"), any applicable listing  requirements of any securities
exchange  on which  stock of the same  class  has  been  listed,  and any  other
requirements  of law or any  regulatory  bodies  having  jurisdiction  over such
issuance  and  delivery.  Pursuant to the terms of the Notice And  Agreement  Of
Exercise Of Option that shall be delivered to the Company upon each  exercise of
the Option,  the Optionee  shall  acknowledge,  represent,  warrant and agree as
follows:

            (a)  All Option Shares shall be acquired solely  for the  account of
the Optionee for  investment  purposes  only and with no view to their resale or
other  distribution of any kind (Note: This provision will be applicable only if
the issuance of the Option  Shares is not  registered at the time of exercise of
the Option);

            (b)  Optionee's  overall  commitment  to  investments  that  are not
readily  marketable  is  not   disproportionate  to  Optionee's  net  worth  and
Optionee's  investment  in the Option and the Option  Shares will not cause such
overall commitments to become excessive;

            (c)  Optionee's  financial  condition is such that Optionee is under
no present or  contemplated  future need to dispose of any portion of the Option
or the Option Shares to satisfy any existing or contemplated  undertaking,  need
or indebtedness;

            (d)  Optionee  has  sufficient knowledge  and experience in business
and financial  matters to evaluate, and Optionee has  evaluated,  the merits and
risks of an investment in the Option and the Option Shares;

            (e)  The address set forth in this Agreement is Optionee's  true and
correct residence, and Optionee has no present intention  of becoming a resident
of any other state or jurisdiction;

            (f)  Optionee  confirms  that  all  documents,  records  and   books
pertaining  to an  investment in the Option and the Option Shares have been made
available or delivered to Optionee.  Optionee further confirms that Optionee has
had the  opportunity  to discuss  the  acquisition  of the Option and the Option
Shares with the  Company,  and Optionee has obtained or been given access to all
information concerning the Company that Optionee has requested;

            (g)  Optionee  has  had  the  opportunity  to  ask questions of, and
receive the answers from, the Company  concerning the terms of the investment in
the Option and the Option Shares and to receive additional information necessary
to verify the accuracy of the information  delivered to Optionee,  to the extent
that  the  Company   possesses  such  information  or  can  acquire  it  without
unreasonable effort or expense;

            (h)  Optionee  understands  that  the  Option  Shares  issuable upon
exercise of the Options  may not be  registered  under the 1933 Act or any state
securities  laws in  reliance on an  exemption  for  private  offerings,  and no
federal or state agency has made any finding or determination as to the fairness
of this investment or any  recommendation  or endorsement of the issuance of the
Option Shares;

            (i)  Optionee acknowledges and is aware of the following:



                                       3



                 (i)  The  Option and the Option Shares constitute a speculative
         investment  and  involve a high  degree of risk of loss by Optionee  of
         Optionee's total investment in the Option and the Option Shares.

                 (ii)  There are substantial restrictions on the transferability
         of the  Option and the Option  Shares.  The Option is not  transferable
         except as  provided  in Section 7 below.  The Option  Shares  cannot be
         transferred,  pledged,  hypothecated,  sold or  otherwise  disposed  of
         unless they are registered under the 1933 Act or an exemption from such
         registration  is available and  established to the  satisfaction of the
         Company;  investors  in the Company  have no rights to require that the
         Option Shares be  registered;  there is no right of  presentment of the
         Option  Shares and there is no  obligation by the Company to repurchase
         any of the Option Shares; and,  accordingly,  Optionee may have to hold
         the Option Shares  indefinitely and it may not be possible for Optionee
         to liquidate Optionee's investment in the Company;

                 (iii) Each  certificate  issued  representing the Option Shares
         shall be imprinted  with a legend that sets forth a description  of the
         restrictions on transferability of those securities,  which legend will
         read substantially as follows:

                 "THE SECURITIES  REPRESENTED BY THIS CERTIFICATE HAVE
                 NOT BEEN  REGISTERED  OR QUALIFIED  UNDER  FEDERAL OR
                 STATE  SECURITIES  LAWS.  THESE SECURITIES MAY NOT BE
                 OFFERED  FOR  SALE,  SOLD,   PLEDGED,   OR  OTHERWISE
                 DISPOSED  OF UNLESS SO  REGISTERED  OR  QUALIFIED  OR
                 UNLESS AN EXEMPTION EXISTS, THE AVAILABILITY OF WHICH
                 IS TO BE  ESTABLISHED BY AN OPINION OF COUNSEL TO THE
                 REGISTERED  HOLDER  (WHICH  OPINION AND COUNSEL SHALL
                 BOTH BE SATISFACTORY TO THE COMPANY)."

            (j)  No  Option  Shares  shall  be  sold or otherwise distributed in
violation of the 1933 Act or any other  applicable  federal or state  securities
laws;

            (k)  The Company  may, without liability for its good faith actions,
place legend  restrictions upon the certificates  representing the Option Shares
and issue "stop  transfer"  instructions  requiring  compliance  with applicable
securities laws and the terms of the Option.

            (l)  The  Optionee  shall report  all  sales of Option Shares to the
Company in writing on a form  prescribed by the Company; and

            (m)  If  and  so  long  as  the  Optionee  is subject  to  reporting
requirements  under  Section  16(a) of the 1934 Act, the  Optionee  shall (i) be
aware that any sale by the Optionee or the Optionee's immediate family of shares
of the  Company's  common  stock or any of the Option  Shares  within six months
before or after any transaction  deemed to be a "purchase" of an equity security
of the Company may create  liability for the Optionee under Section 16(b) of the
1934 Act, (ii) consult with the Optionee's  counsel regarding the application of
Section 16(b) of the 1934 Act prior to any exercise of the Option,  and prior to
any sale of shares of the  Company's  common stock or the Option  Shares,  (iii)
furnish the Company with a copy of each Form 4 filed by the Optionee's, and (iv)
timely file all reports required under the federal securities laws.

            The  restrictions described in Paragraphs  6(a)-(m) above, or notice
thereof,  may be placed  on the  certificates  representing  the  Option  Shares
purchased  pursuant  to the  Option,  and the  Company  may


                                       4



refuse to issue the  certificates  or to transfer the Option Shares on its books
unless it is satisfied that no violation of such restrictions will occur.

         7.  TRANSFERABILITY  OF OPTION.  No Option shall be transferable by the
Optionee  otherwise than by will or by the laws of descent and  distribution or,
in the case of a Non-Qualified  Option,  pursuant to a domestic  relations order
(within the meaning of Rule 12a-12  promulgated under the 1934 Act), and Options
shall be exercisable  during the lifetime of an Optionee only by the Optionee or
the Optionee's guardian or legal representative.  Notwithstanding the foregoing,
Non-Qualified  Options may be transferred to Permitted  Transferees  (as defined
below)  of the  Optionee.  The terms of an Option  shall be final,  binding  and
conclusive  upon  the  beneficiaries,   executors,   administrators,  heirs  and
successors of the Optionee. A "Permitted  Transferee" means Optionee's immediate
family, trusts solely for the benefit of such family members and partnerships in
which such family members and/or trusts are the only partners. For this purpose,
immediate  family of a person  means the  person's  spouse,  parents,  children,
stepchildren  and  grandchildren  and the  spouses  of such  parents,  children,
stepchildren and grandchildren.

         8. ADJUSTMENT BY STOCK SPLIT,  STOCK DIVIDEND,  ETC. If at any time the
Company  increases or decreases the number of its  outstanding  shares of common
stock, or changes in any way the rights and privileges of such shares,  by means
of the payment of a stock  dividend or the making of any other  distribution  on
such shares payable in its common stock, or through a stock split or subdivision
of  shares,   or  a  consolidation  or  combination  of  shares,  or  through  a
reclassification  or  recapitalization  involving its common stock, the numbers,
rights and privileges of the shares of common stock included in the Option shall
be  increased,  decreased  or changed in like  manner as if such shares had been
issued  and  outstanding,  fully  paid  and  nonassessable  at the  time of such
occurrence.

         9. MERGER OR CONSOLIDATION.

            (a)  Upon the occurrence of any of the following events, and subject
to the  30-day  period  provided  for  in  Subsection  9(b),  the  Option  shall
automatically  terminate  and be of no further  force or effect  whatever if and
only if the notice described in Subsection 9(b) has been given to Optionee:  (i)
the merger or consolidation of the Company with one or more other  corporations,
regardless of which entity  survives the  transaction;  (ii) the  dissolution or
liquidation  of the  Company;  (iii) the  appointment  of a receiver for all, or
substantially all, of the Company's assets or business;  (iv) the appointment of
a trustee  for the  Company  after a petition  has been filed for the  Company's
reorganization under applicable statutes;  or (v) the sale, lease or exchange of
all, or substantially all, of the Company's assets and business.

            (b)  If any of the  events  described  in  clauses (i), (ii), (iii),
(iv),  or (v) of  Subsection  9(a) occurs,  then the Company,  at the  Company's
option,  may cause the Option to terminate  and be of no further force or effect
whatever if the Company  gives  written  notice to the Optionee at least 30 days
prior to the  occurrence of any such event.  After  receipt of such notice,  the
Optionee may at any time before the occurrence of the event requiring the giving
of notice  exercise the  unexercised  portion of the Option as to all the shares
covered   thereby  and  without  regard  to  the   restrictions   set  forth  in
Subparagraphs  3(a) and 3(b),  except  that the  portion of the  Option  thereby
becoming exercisable that shall be considered an incentive stock option shall be
subject  to the  limitations  of  Section  16 of the Plan.  Notwithstanding  the
foregoing, if the notice given under this Subsection 9(b) is given fewer than 30
days prior to  occurrence  of the event,  then the  Option  shall not  terminate
pursuant to Subsection 9(a), and may be exercised,  until 30 days after the date
on which the  notice was given.  If no notice  shall be given with  respect to a
transaction  described in clauses (i),  (ii),  or (v) of  Subsection  9(a),  the
provisions of Subsection 9(a) shall not apply and the Option shall not terminate
until the  termination  is pursuant to Subsection  9(a) or any other  applicable
provision of this  Agreement.  Notice  pursuant to this Subsection 9(b) shall be
given pursuant to the provisions of Section 13 of this Agreement.



                                       5



         10. COMMON STOCK TO BE RECEIVED  UPON  EXERCISE.  Optionee  understands
that the Company is under no  obligation  to register the issuance of the Option
Shares or the resale of the Option  Shares  under the 1933 Act,  and that in the
absence of any such  registration,  the Option Shares cannot be sold unless they
are sold  pursuant to an  exemption  from  registration  under the 1933 Act. The
Company  is  under no  obligation  to  comply,  or to  assist  the  Optionee  in
complying,  with any exemption  from such  registration  requirement,  including
supplying the Optionee with any information necessary to permit routine sales of
the Option  Shares under Rule 144 of the  Securities  and  Exchange  Commission.
Optionee  also  understands  that with  respect  to Rule 144,  routine  sales of
securities  made in reliance upon such Rule can be made only in limited  amounts
in accordance  with the terms and  conditions of the Rule,  and that in cases in
which the Rule is inapplicable,  compliance with either  Regulation A or another
disclosure  exemption  under the 1933 Act will be  required.  Thus,  the  Option
Shares will have to be held  indefinitely in the absence of  registration  under
the 1933 Act or an exemption from registration.

             Furthermore,  the Optionee fully  understands that issuance of  the
Option  Shares  may not be  registered  under  the  1933  Act and  that if their
issuance is not  registered,  they will be issued in reliance  upon an exemption
which is available only if Optionee  acquires such shares for investment and not
with a view to distribution.  Optionee is familiar with the phrase "acquired for
investment  and not with a view to  distribution"  as it relates to the 1933 Act
and the special meaning given to such term in various releases of the Securities
and Exchange Commission.

         11.  PRIVILEGE OF OWNERSHIP.  Optionee shall not have any of the rights
of a stockholder  with respect to the shares covered by the Option except to the
extent that one or more  certificates  for such shares shall be delivered to him
upon exercise of the Option.

         12.  RELATIONSHIP TO EMPLOYMENT OR POSITION.  Nothing contained in this
Agreement  (i)  shall  confer  upon the  Optionee  any  right  with  respect  to
continuance of Optionee's  employment  by, or position or  affiliation  with, or
relationship to, the Company,  or (ii) shall interfere in any way with the right
of the Company at any time to terminate the Optionee's  employment by,  position
or affiliation with, or relationship to, the Company.

         13. NOTICES.  All  notices,  requests,  demands,  directions  and other
communications  ("Notices")  concerning  this Agreement  shall be in writing and
shall be mailed or delivered  personally  or sent by  telecopier or facsimile to
the  applicable  party at the  address  of such  party set  forth  below in this
Section  13.  When  mailed,  each  such  Notice  shall be sent by  first  class,

hereunder  be waived  except by an  instrument  in  writing  signed by the party
sought to be charged with such  amendment  or waiver,  (c) shall be construed in

representatives  and assigns,  except as above set forth. All pronouns contained
herein and any  variations  thereof  shall be deemed to refer to the  masculine,

                   NOTICE AND AGREEMENT OF EXERCISE OF OPTION

         I hereby  exercise my GSL Energy  Corporation  Stock Option dated as of
August 10, 2005 as to ________  shares of the $.001 par value  common stock (the
"Option  Shares") of GSL Energy  Corporation (the "Company") at a purchase price
of $____  per  share.  The total  exercise  price  for  these  Option  Shares is
$________. Enclosed is payment in the form of ___________________.

         Enclosed  is  the  payment  specified  in  Paragraph  4  of  my  Option
Agreement.

         I understand  that no Option Shares will be issued unless and until, in
the opinion of the Company,  there has been full  compliance with any applicable
registration  requirements  of the  Securities  Act of  1933,  as  amended,  any
applicable listing requirements of any securities exchange on which stock of the
same class is then listed,  and any other  requirements of law or any regulatory
bodies  having   jurisdiction   over  such  issuance  and  delivery.   I  hereby
acknowledge, represent, warrant and agree, to and with the Company as follows:

         a.       The Option  Shares I am purchasing  are being  acquired for my
                  own account for  investment  purposes only and with no view to
                  their resale or other  distribution  of any kind, and no other
                  person  (except,  if I am  married,  my  spouse)  will own any
                  interest therein.

         b.       I will  not sell  or dispose of my Option  Shares in violation
                  of  the  Securities  Act  of  1933,  as amended,  or any other
                  applicable federal or state securities laws.

         c.       I agree that the Company may,  without  liability for its good
                  faith actions, place legend restrictions upon my Option Shares
                  and issue "stop transfer"  instructions  requiring  compliance
                  with applicable securities laws and the terms of my Option.

         d.       I will  report  all sales of Option  Shares to the  Company in
                  writing on a form prescribed by the Company.

         e.       If and so long as I am subject to reporting requirements under
                  Section  16(a) of the 1934 Act), I recognize  that any sale by
                  me or my  immediate  family of the  Company's  $.001 par value
                  common stock may create  liability  for me under Section 16(b)
                  of the 1934 Act ("Section 16(b)"). Therefore, I have consulted
                  with my counsel  regarding the application of Section 16(b) to
                  this exercise of my Option.

         f.       I will consult with my counsel  regarding the  application  of
                  Section  16(b) before I make any sale of the  Company's  $.001
                  par value common  stock,  including the Option  Shares,  and I
                  will  furnish the Company with a copy of each Form 4 or Form 5
                  filed by me and will  timely  file all  reports  that I may be
                  required to file under the federal securities laws.
