                             SUBSCRIPTION AGREEMENT

      Dr. David Brown, hereby agrees to purchase an aggregate of 1,416,667
shares of Class A Common Stock, par value $0.001 per share (the "Shares"), of
Laser Energetics, Inc., an Oklahoma corporation (the "Company"), for an
aggregate purchase price of $ 400,000 (the "Offer"). After adjusting for the
Company's planned 3.4018426555 for one stock split (for which the Company's
Board of Directors has fixed prior to the opening of business on July 7, 2005 as
the record date), the purchase price of the Shares in the Offer will be $0.083
per share, however, prior to the record date, the purchase price will be
$0.282352940 per share. The Offer is part of a private placement offering (the
"Private Placement") by the Company to raise up to an aggregate of $5,000,000
(the "Maximum Private Placement") on the same terms and conditions as the Offer.

1.    I hereby represent the following:

      (a) I have been given the opportunity to ask questions of and receive
answers from Company management concerning the Company, the Shares and the Offer
and to examine such books, records and other documents of the Company as I have
desired.

      (b) I have sought such legal, accounting, business and tax advice as I
have considered necessary to make an informed investment decision regarding the
Offer.

      (c) I am familiar with the past and proposed activities of the Company,
recognize that the Company has only 6 years of operating history in the business
activities in which it proposes to engage, and realize that an investment in the
Shares involves a high degree of risk.

      (d) I have sufficient knowledge and experience in financial and business
matters to be capable of evaluating the merits and risks of the prospective
investment in the Shares and of making an informed investment decision with
respect thereto.

2.    I hereby acknowledge that, except as set forth in Section 3 below:

      (a) there will be no public market for the Shares;

      (b) it may not be possible to readily liquidate my investment;

      (c) the Shares have not been registered under the Securities Act of 1933

                                      -1-
<PAGE>

(the "'33 Act") or the applicable State law based on the exemptions from
registration contained in Section 4(2) of the '33 Act or Rule 506 promulgated
thereunder, and the Company is relying in part on the truthfulness of my
respresentations contained herein (including without limitation ss. 4 hereof) in
determining the availability of such exemptions from registration;

      (d) The Company does not intend to register the Shares under the '33 Act
or to supply the information required to enable me to make a sale of the Shares
under Rule 144 promulgated under the Act;

      (e) the Shares are subject to restrictions on transferability and resale
and may not be transferred or resold except as permitted under the '33 Act and
applicable State law, pursuant to registration or exemption therefrom; and

      (f) neither the Securities and Exchange Commission nor the securities
commissioner of the applicable State has recommended or endorsed the purchase of
the Shares.

3. Subject to my execution of all Lock-up Agreements (as defined below), the
Company agrees to file a registration statement on Form SB-2 covering the
re-sale of the Shares with the Securities and Exchange Commission, if and when
the Company files a registration statement on Form SB-2 covering the re-sale of
the shares of Class A Common Stock of the Company held by iVoice, Inc.
Contemporaneously with the execution of this Subscription Agreement, I agree to
execute the Lock-Up Agreement in the form of Exhibit "A" attached hereto, and
agree to execute such other agreement restricting the transfer of the Shares as
required by Cornell Capital Partners, LP, or any of its successors or assigns or
substituted lenders or investors of the Company (collectively, the "Lock-up
Agreements").

4. I represent and warrant that I am an "Accredited Investor" as defined in Rule
501(a) of Regulation D because (check applicable item):

            |X| My net worth, or the joint net worth of myself and my spouse,

of the Investment Advisors Act of 1940; an entity described in Section 501(c)(3)
of the Internal Revenue Code, not formed for the purpose of acquiring the

total assets in excess of $5,000,000, not formed for the specific purpose of
acquiring the securities offered, whose purchase is directed by a sophisticated
person.

5. I am a legal resident of the state listed as my "Mailing Address" on the
signature page of this Subscription Agreement.

6. I am acquiring the Shares purely for investment purposes for my own account
and not for resale or distribution, and I have not entered into any other
agreement, understanding, commitment or other arrangement with any person
regarding transfer of the Shares.

7. I will promptly execute such other instruments or documents as the Company's
management may reasonably require in connection with a purchase of the Shares,
and I will promptly provide all personal and financial information which the
Company's management deems necessary or appropriate in connection with a
purchase of the Shares.

8. I understand that this Offer has not been reviewed by the Securities and
Exchange Commission or the securities regulatory authorities of the applicable
State. All documents, records and books pertaining to this investment have been
made available for inspection by me and my attorneys, accountants, business

shares of Class A Common Stock issued and outstanding immediately prior to the
Private Placement, and there could be issued up to an additional 60,240,964
shares of Class A Common Stock in the Maximum Private Placement. I acknowledge
that as a shareholder of the Company I will not have any preemptive rights with
regard to additional securities to be issued by the Company and that accordingly
my proportional share of the outstanding shares of the Common Stock will
decrease following each new issuance of Common Stock by the Company.
