            FOR VALUE RECEIVED, the undersigned, Laser Energetics, Inc., a
Florida corporation (the "Payor"), having its executive office and principal
place of business at 3535 Quaker Bridge Road, Suite 601, Mercerville, New Jersey

specify in writing, the principal sum of Eighty Five Thousand Dollars
($85,000.00), or so much thereof as shall be advanced by the Payee to the Payor,
pursuant to the terms hereof, in such coin or currency of the United States of
America as at the time shall be legal tender for the payment of public and
private debts.

      1. Payment; Maturity Date.

            1.1. The Payor is a party to a certain financing transaction with

            1.2. In no event shall the Payee be entitled to receive interest,
however characterized and including other consideration received in connection
with this Note, at an effective rate in excess of the maximum rate permitted by
law. In the event that a court of competent jurisdiction shall determine that
such amounts paid or agreed to be paid by the Payor in connection with this Note
causes the effective interest rate on this Note to exceed the maximum rate
permitted by law, such interest or other consideration shall automatically be
reduced to a rate which results in an effective interest rate under this Note
equal to the maximum rate permitted by law over the term hereof, and, in such

<PAGE>

event, the Payee shall, at the Payee's sole and absolute discretion, either
apply to the reduction of the unpaid principal balance of this Note any amounts
received by it deemed to constitute excessive interest or refund such excess to
Payor.

substitution for this Note, if destroyed, lost or stolen. In the case of
destruction, loss or theft, the Payee shall furnish to the Payor indemnity
reasonably satisfactory to the Payor, and in the case of mutilation, the Payee
shall also furnish to the Payor evidence to its reasonable satisfaction of the
mutilation, destruction, loss or theft of this Note and of the ownership
thereof. Any replacement Note so issued shall be in the same outstanding
principal amount as this Note and dated the date to which interest shall have
been paid on this Note, or if no interest shall have yet been paid, dated the
date of this Note.

            2.2. Every Note issued pursuant to the provisions of Section 2.1
hereof in substitution for this Note shall constitute an additional contractual

whole at any time, or in part from time to time, without penalty or premium.

then to outstanding principal.

payable; or

      5. Suits for Enforcement and Remedies. If Payor defaults in the
performance of any of the terms or provisions of this Note, or in any agreement
or document referred to herein, the principal sum or so much of the principal
remaining unpaid with all interest accrued thereon, shall, at the option of the
Payee, become due and payable immediately, and interest on the principal sum
shall be computed at the lesser of eighteen (18%) percent per annum or the
highest interest rate permitted to be charged by applicable law. If any one or
more defaults shall occur and be continuing, the Payee may proceed to protect
and enforce such Payee's rights either by suit in equity or by action at law, or

unpaid sum of this Note, all reasonable costs and expenses incurred by the Payee
in connection therewith, including, without limitation, reasonable attorneys'
fees and disbursements, except in the event the action by Payee is not
meritorious.

            6.3. No forbearance, indulgence, delay or failure to exercise any
right or remedy with respect to this Note shall operate as a waiver, nor as an
acquiescence in any default, nor shall any single or partial exercise of any
right or remedy preclude any other or further exercise thereof or the exercise
of any other right or remedy.

            6.4. This Note may not be modified except by a writing duly executed
by the Payor and the Payee.

called for hereunder.

               Lead Investor Warrant for the Purchase of Shares of
                                  Common Stock

No. LI-1                                                       November 28, 2005

            FOR VALUE RECEIVED, LASER ENERGETICS, INC., an Oklahoma corporation
(the "Company"), hereby certifies that Dr. David Brown or its registered assigns
(the "Holder") is entitled to purchase from the Company, subject to the
provisions of this Warrant (the "Warrant"), at any time on or after the date
hereof (the "Initial Exercise Date"), and prior to 12:01 A.M., New York City
time, on August 5, 2008 (the "Termination Date"), 1,000,000 fully paid and
non-assessable shares of the Class A Common Stock, $.001 par value per share
(the "Common Stock"), of the Company, at an exercise price of $0.10 per share of
Common Stock for an aggregate exercise price of One Hundred Thousand Dollars
($100,000.00) (the aggregate purchase price payable for the Warrant Shares
hereunder is hereinafter sometimes referred to as the "Aggregate Exercise
Price"). The number of shares of Common Stock to be received upon exercise of
this Warrant and the price to be paid for each share of Common Stock are subject
to possible adjustment from time to time as hereinafter set forth. The shares of
Common Stock or other securities or property deliverable upon such exercise as
adjusted from time to time is hereinafter sometimes referred to as the "Warrant
Shares." The exercise price of a share of Common Stock in effect at any time and
as adjusted from time to time is hereinafter sometimes referred to as the "Per
Share Exercise Price." The Per Share Exercise Price is subject to adjustment as
hereinafter provided; in the event of any such adjustment, the number of Warrant
Shares shall also be adjusted, by dividing the Aggregate Exercise Price by the
Per Share Exercise Price in effect immediately after such adjustment. The
Aggregate Exercise Price is not subject to adjustment except to the extent of
any partial exercise of this Warrant. This Warrant may constitute one in a
series of warrants (the "Lead Investor Warrants") which includes this Warrant
and any other Lead Investor Warrant for the Purchase of Shares of Common Stock
of the Company, of like tenor hereto.

<PAGE>

            1. Exercise of Warrant.

            (a) This Warrant may be exercised in whole or in part, at any time
by its holder commencing on the Initial Exercise Date and prior to the
Termination Date:

                  (i) by presentation and surrender of this Warrant, together
      with the duly executed subscription form attached at the end hereof, at
      the address set forth in Subsection 8(a) hereof, together with payment, by
      certified or official bank check or wire transfer payable to the order of
      the Company, of the Aggregate Exercise Price or the proportionate part
      thereof if exercised in part; or

                  (ii) by presentation and surrender of this Warrant, together
      with the duly executed cashless exercise form attached at the end hereof
      (a "Cashless Exercise") at the address set forth in Subsection 8(a)
      hereof. The exchange of Common Stock for the Warrant shall take place on
      the date specified in the Cashless Exercise Form or, if later, the date
      the Cashless Exercise Form is surrendered to the Company (the "Exchange
      Date"). Such presentation and surrender shall be deemed a waiver of the
      Holder's obligation to pay the Aggregate Exercise Price, or the
      proportionate part thereof if this Warrant is exercised in part. In the
      event of a Cashless Exercise, this Warrant shall represent the right to
      subscribe for and to acquire the number of shares of Common Stock equal to
      (x) the number of shares of Common Stock specified by the Holder in its
      Cashless Exercise Form (the "Total Number") (such number not to exceed the
      maximum number of shares of Common Stock subject to this Warrant, as may
      be adjusted from time to time) less (y) the number of shares of Common
      Stock equal to the quotient obtained by dividing (A) the product of the
      Total Number and the existing Per Share Exercise Price by (B) the fair
      market value per share of Common Stock at such time, as determined by the
      Board of Directors of the Company in good faith (the "Per Share FMV"). No
      Cashless Exercise shall be effected unless the Per Share FMV is greater
      than the Per Share Exercise Price as of the Exchange Date.

            (b) If this Warrant is exercised in part only, the Company shall,
upon presentation of this Warrant upon such exercise, execute and deliver (along
with the certificate for the Warrant Shares purchased) a new Warrant evidencing
the rights of the Holder hereof to purchase the balance of the Warrant Shares
purchasable hereunder upon the same terms and conditions as herein set forth.
Upon proper exercise of this Warrant, the Company promptly shall deliver
certificates for the Warrant Shares to the Holder duly legended as authorized by
the subscription form. No fractional shares or scrip representing fractional
shares shall be issued upon exercise of this Warrant; provided that the Company
shall pay to the Holder of the Warrant cash in lieu of such fractional shares.

            (c) The certificates representing the Warrant Shares shall bear the
following legends:

      THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE
      "SECURITIES ACT"), OR ANY APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE
      SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED OR OTHERWISE TRANSFERRED
      IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO SUCH
      SECURITIES UNDER THE SECURITIES ACT OR AN EXEMPTION FROM THE SECURITIES
      ACT. ANY SUCH TRANSFER MAY ALSO BE SUBJECT TO COMPLIANCE WITH

                                      -2-
<PAGE>

      APPLICABLE STATE SECURITIES LAWS AND THE LAWS OF OTHER APPLICABLE
      JURISDICTIONS.

      THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
      RESTRICTIONS ON TRANSFER SET FORTH IN SECTION 12 OF THE LEAD INVESTOR
      WARRANT THAT WAS EXCERCISED FOR THE PURCHASE OF SUCH SECURITIES, COPIES OF
      WHICH ARE AVAILABLE FROM LASER ENERGETICS, INC.

            2. Reservation of Warrant Shares; Fully Paid Shares; Taxes. The
Company hereby represents that it has, and until expiration of this Warrant
agrees that it shall, reserve for issuance or delivery upon exercise of this
Warrant, such number of shares of the Common Stock as shall be required for
issuance and/or delivery upon exercise of this Warrant in full, and agrees that
all Warrant Shares so issued and/or delivered will be validly issued, fully paid
and non-assessable, and further agrees to pay all taxes (other than income
taxes) and charges that may be imposed upon such issuance and/or delivery. The
Company shall not, however, be required to pay any tax which may be payable in
respect of any transfer involved in the issue or delivery of Common Stock (or
other securities or assets) in a name other than that in which the Warrants so
exercised were registered, and no such issue or delivery shall be made unless
and until the person requesting such issue has paid to the Company the amount of
such tax or has established, to the satisfaction of the Company, that such tax
has been paid.

            3. Protection Against Dilution.

            (a) In case the Company shall hereafter (i) pay a dividend or make a
distribution on its capital stock in shares of Common Stock, (ii) subdivide its
outstanding shares of Common Stock into a greater number of shares, (iii)
combine its outstanding shares of Common Stock into a smaller number of shares
or (iv) issue by reclassification of its Common Stock any shares of capital
stock of the Company (each of (i) through (iv) an "Action"), the Per Share
Exercise Price shall be adjusted to be equal to a fraction, the numerator of
which shall be the Aggregate Exercise Price and the denominator of which shall
be the number of shares of Common Stock or other capital stock of the Company
that the Holder would have held (solely as a result of the exercise of this
Warrant and the operation of such Action) immediately following such Action if
this Warrant had been exercised immediately prior to such Action. An adjustment
made pursuant to this Subsection 3(b) shall become effective immediately after
the record date in the case of a dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision,
combination or reclassification.

            (b) In the event of any capital reorganization or reclassification
not otherwise covered in this Section 3, or any consolidation or merger to which
the Company is a party other than a merger or consolidation in which the Company
is the continuing corporation, or in case of any sale or conveyance to another
entity of the property of the Company as an entirety or substantially as an
entirety, or in the case of any statutory exchange of securities with another
corporation (including any exchange effected in connection with a merger of a
third corporation into the Company), the Holder of this Warrant shall have the
right thereafter to receive on the exercise of this Warrant the kind and amount
of securities, cash or other property which the Holder would have owned or have
been entitled to receive immediately after such reorganization,
reclassification, consolidation, merger, statutory exchange, sale or conveyance

                                      -3-
<PAGE>

had this Warrant been exercised immediately prior to the effective date of such
reorganization, reclassification, consolidation, merger, statutory exchange,
sale or conveyance and in any such case, if necessary, appropriate adjustment
shall be made in the application of the provisions set forth in this Section 3
with respect to the rights and interests thereafter of the Holder of this
Warrant to the end that the provisions set forth in this Section 3 shall
thereafter correspondingly be made applicable, as nearly as may reasonably be,
in relation to any shares of stock or other securities or property thereafter
deliverable on the exercise of this Warrant. The above provisions of this
Subsection 3(b) shall similarly apply to successive reorganizations,
reclassifications, consolidations, mergers, statutory exchanges, sales or
conveyances.

            (c) Whenever the Per Share Exercise Price payable upon exercise of
this Warrant is adjusted pursuant to this Section 3, the number of shares of
Common Stock underlying this Warrant shall simultaneously be adjusted to equal
the number obtained by dividing the Aggregate Exercise Price (as the same shall
be reduced to the extent of any partial exercise of this Warrant) by the
adjusted Per Share Exercise Price.

            (d) If, as a result of an adjustment made pursuant to this Section
3, the Holder shall become entitled to receive, upon exercise of the Warrant,
shares of two or more classes of capital stock or shares of Common Stock and
other capital stock of the Company, the Board of Directors (whose determination
shall be conclusive) shall determine the allocation of the adjusted Per Share
Exercise Price between or among shares or such classes of capital stock or
shares of Common Stock and other capital stock.

            4. Limited Transferability. This Warrant may not be sold,
transferred, assigned or hypothecated by the Holder except in compliance with
the provisions of the Act and the applicable state securities "blue sky" laws,
and is so transferable only upon the books of the Company which it shall cause
to be maintained for such purpose. The Company may treat the registered Holder
of this Warrant as he or it appears on the Company's books at any time as the
Holder for all purposes.

            5. Loss, etc., of Warrant. Upon receipt of evidence satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant, and
of indemnity reasonably satisfactory to the Company (which may include a bond),
if lost, stolen or destroyed, and upon surrender and cancellation of this
Warrant, if mutilated, the Company shall execute and deliver to the Holder a new
Warrant of like date, tenor and denomination.

            6. Investment Intent.

            (a) The Holder represents, by accepting this Warrant, that it
understands that this Warrant and any securities obtainable upon exercise of
this Warrant have not been registered for sale under Federal or state securities
laws and are being offered and sold to the Holder pursuant to one or more
exemptions from the registration requirements of such securities laws. The
Holder is an "accredited investor" within the meaning of Regulation D under the
Securities Act of 1933, as amended (the "Act"). In the absence of an effective
registration of such securities or an exemption therefrom, any certificates for
such securities shall bear the legend set forth on the first page hereof. The
Holder understands that it must bear the economic risk of its investment in this
Warrant and any securities obtainable upon exercise of this Warrant for an

                                      -4-
<PAGE>

indefinite period of time, as this Warrant and such securities have not been
registered under Federal or state securities laws and therefore cannot be sold
unless subsequently registered under such laws, unless as exemption from such
registration is available.

            (b) The Holder, by its acceptance of its Warrant, represents to the
Company that it is acquiring this Warrant and will acquire any securities
obtainable upon exercise of this Warrant for its own account for investment and
not with a view to, or for sale in connection with, any distribution thereof in
violation of the Act. The Holder agrees that this Warrant and any such
securities will not be sold or otherwise transferred unless (i) a registration
statement with respect to such transfer is effective under the Act and any
applicable state securities laws or (ii) such sale or transfer is made pursuant
to one or more exemptions from the Act.

            7. Status of Holder. This Warrant does not confer upon the Holder
any right to vote or to consent to or receive notice as a stockholder of the
Company, as such, in respect of any matters whatsoever, or any other rights or
liabilities as a stockholder, prior to the exercise hereof.

            8. Notices. No notice or other communication under this Warrant
shall be effective unless, but any notice or other communication shall be
effective and shall be deemed to have been given if, the same is in writing and
is mailed by first-class mail, postage prepaid, addressed to:

            (a) the Company c/o 3535 Quakerbridge Road, Suite 700, Mercerville,
      New Jersey, 08619, Attention: President, or such other address as the
      Company has designated by notice to the Holder; or

            (b) the Holder at 2665 Oak Ridge Court, Fort Myers, Florida 33901,
      or such other address as the Holder has designated by notice to the
      Company.

            9. Headings. The headings of this Warrant have been inserted as a
matter of convenience and shall not affect the construction hereof.

            10. Applicable Law. This Warrant shall be governed by and construed
in accordance with the law of the State of New York without giving effect to
principles of conflicts of law thereof.

            11. Amendments. This Warrant may be amended only by mutual written
agreement of the Company and the holder or holders holding Lead Investor
Warrants exercisable for a majority of the shares of Common Stock issuable upon
exercise of all then-outstanding Lead Investor Warrants (the "Majority
Holders"), and the Company may take any action herein prohibited or omit to take
any action herein required to be performed by it, and any breach of any
