FOR VALUE RECEIVED, DrTattoff, LLC, a California limited liability company,

“Borrower”), hereby promises to pay to Ian Kirby, located at 560 N. Kings Road
#3, West Hollywood, CA 90048 (the “Holder”), without demand, the sum of Seventy
Five Thousand Dollars ($75,000), plus all accrued and unpaid interest, on the
earlier of (i) the date which is 180 days following Issue Date, or (ii) the date
which is two (2) days after the effective date of the Merger (as defined below)
(the “Maturity Date”), unless the Holder elects to convert this Note as set
forth in Article II.

ARTICLE I

GENERAL PROVISIONS

1.1 Interest Rate. Interest on the outstanding principal balance of this Note
shall accrue, beginning from the date hereof, at a rate of 10% per annum,
compounded quarterly. Interest on the outstanding principal balance of the Note
shall be computed on the basis of the actual number of days elapsed and a year
of three hundred and sixty (360) days and shall be payable on the Maturity Date,
upon earlier prepayment of this Note or in the form of shares of New Securities
or Conversion Shares (each as defined below), upon conversion of this Note as
set forth in Section 1.2 below.

1.2 Conversion Privileges. The Note shall be payable in full on the Maturity
Date, unless previously converted into New Securities or Conversion Shares, in
accordance with Article II hereof.

1.3 Prepayment. This Note shall not be subject to any prepayment penalty in the
event the Company determines in its sole discretion to prepay all or any portion
of this Note.

1.4 In no event shall the Borrower be obligated to pay interest and fees in
excess of the amount permitted by law. Regardless of any provision herein or in
any agreement made in connection herewith, Holder shall never be entitled to
receive, charge or apply, as interest on any indebtedness relating hereto, any
amount in excess of the maximum amount of interest permissible under applicable
law. If Holder ever receives, collects or applies any such excess, it shall be
deemed a partial repayment of principal and treated as such; and if principal is
paid in full, any remaining excess shall be refunded to the Borrower. This
paragraph shall control every other provision hereof and of any other agreement
made in connection herewith.

 
 

--------------------------------------------------------------------------------

 

ARTICLE II

CONVERSION RIGHTS

The Holder shall have the right to convert the principal and any interest due
under this Note into New Securities or Conversion Shares as set forth below.

2.1. Borrower's Proposed Merger. The Borrower intends to merge itself with and
into Lifesciences Opportunities, Inc., a Delaware corporation (the "Merger").
The rights provided in this Article II shall not be exercisable unless and until
completion of the Merger. For purposes of this Article II, the term Borrower
shall refer to the surviving entity after completion of the Merger. 

2.2 Conversion into the Borrower’s New Securities.

(a) Conversion Right. Provided that the Merger is consummated, upon written
notice to the Borrower, the Holder may, at its sole option, at the effective
date of the Merger (as defined below), or at any time thereafter until the
principal balance of this Note, together with all accrued and unpaid interest,
is paid in full, convert the entire outstanding principal hereunder and all
accrued and unpaid interest thereon into such number of shares of fully paid and
non-assessable equity securities issued by the Borrower to its members in
connection with the conversion of their Membership Interests in the Company
pursuant to the Merger (the “New Securities”), that is equal to the quotient of
(A) the outstanding principal hereunder plus all accrued and unpaid interest
thereon divided by (B) the Conversion Price (as defined below). In addition, in
connection with such conversion, the Holder shall receive rights as a purchaser
and holder of New Securities (including, without limitation, customary
registration rights) no less favorable in the aggregate and in any single
instance than those granted to any other purchaser of New Securities. The
Borrower agrees that it has no right to prevent the Holder from effecting such
conversion without the Holder’s consent, whether by attempting to prepay this
Note (whether or not there shall have been a default hereunder) or otherwise.
The “Conversion Price” shall (i) if the New Securities are common stock, par
value $0.001 per share (the “Common Stock”), be equal to the Common Stock
Equivalent Price (as defined below) or (ii) if the New Securities are
convertible capital stock, the Conversion Price shall be an amount equal to the
Common Stock Equivalent Price multiplied by the number of shares of Common Stock
into which one share of such convertible capital stock is convertible. The
“Common Stock Equivalent Price” shall initially be the closing offering price in
the Next Financing and shall be adjusted as set forth in Section 2.2(d) below.

(b) Fractional Shares. Upon the conversion of this Note, fractional shares
representing New Securities shall be issued only if fractional shares are
issuable in connection with the Next Financing to investors generally. If no
fractional shares are so issuable, then with respect to any fraction of a share
called for upon the conversion of this Note or any portion hereof, a cash amount
equal to such fraction shall be paid to the Holder.

(c) Conversion Mechanics.
 
(i) Notice of Merger. The Borrower shall notify the Holder in writing not less
than 5 business days prior to the expected effective date of the Merger (the
“Effective Date”). Such notice shall include all of the material terms of the
Merger and shall include, as promptly as such documents are available,
then-current drafts of the transaction documents for the Merger. Following such
notice, the Borrower shall provide the Holder with any transaction documents or
revised drafts thereof at the same time that such transaction documents or
drafts are made generally available to Members of the Company in connection with
the Merger.

 
2

--------------------------------------------------------------------------------

 

(ii) Conversion Notice. The right of conversion shall be exercised by the Holder
by delivering to the Borrower, no later than the business day prior to the date
of which this Note, including all accrued and unpaid interest thereon, is paid
in full, a conversion notice substantially in the form attached hereto as
Exhibit A (the “Conversion Notice”), appropriately completed and duly signed,
and by surrender not later than five (5) business days thereafter of this Note
(or if the original Note has been lost or destroyed, an affidavit of Holder in
customary form certifying as to such loss or destruction). Promptly after the
receipt of the Conversion Notice and the original Note (or if the original Note
has been lost or destroyed, an affidavit of Holder in customary form certifying
as to such loss or destruction), the Borrower shall issue and deliver, or cause
to be delivered, to the Holder, a certificate or certificates for the number of
shares of New Securities issuable to such Holder in accordance with Section
2.2(a). Such conversion shall be deemed to have been effected as of the date of
consummation of surrender of the Original Note, or affidavit, as the case may be
(the “Conversion Date”), and the person or persons entitled to receive the
shares of New Securities issuable upon conversion shall be treated for all
purposes as the holder or holders of record of such shares as of the close of
business on the Conversion Date.
 
(d)  The number and kind of shares or other securities to be issued upon
conversion determined pursuant to Section 2.2(a), shall be subject to adjustment
from time to time upon the happening of certain events while this conversion
right remains outstanding, as follows:
 
(i) Merger, Sale of Assets, etc. If the Borrower at any time shall consolidate
with or merge into or sell or convey all or substantially all its assets to any
other corporation, this Note, as to the unpaid principal portion thereof and
accrued interest thereon, shall thereafter be deemed to evidence the right to
purchase such number and kind of shares or other securities and property as
would have been issuable or distributable on account of such consolidation,
merger, sale or conveyance, upon or with respect to the securities subject to
the conversion or purchase right immediately prior to such consolidation,
merger, sale or conveyance. The foregoing provision shall similarly apply to
successive transactions of a similar nature by any such successor or purchaser.
Without limiting the generality of the foregoing, the anti-dilution provisions
of this Section shall apply to such securities of such successor or purchaser
after any such consolidation, merger, sale or conveyance.

(ii) Reclassification, etc. If the Borrower at any time shall, by
reclassification or otherwise, change the Common Stock into the same or a
different number of securities of any class or classes that may be issued or
outstanding, this Note, as to the unpaid principal portion thereof and accrued
interest thereon, shall thereafter be deemed to evidence the right to purchase
an adjusted number of such securities and kind of securities as would have been
issuable as the result of such change with respect to the Common Stock
immediately prior to such reclassification or other change.

(iii) Stock Splits, Combinations and Dividends. If the shares of Common Stock
are subdivided or combined into a greater or smaller number of shares of Common
Stock, or if a dividend is paid on the Common Stock in shares of Common Stock,
the Common Stock Equivalent Price shall be proportionately reduced in case of
subdivision of shares or stock dividend or proportionately increased in the case
of combination of shares, in each such case by the ratio which the total number
of shares of Common Stock outstanding immediately after such event bears to the
total number of shares of Common Stock outstanding immediately prior to such
event.
 
(e) Whenever any action is taken pursuant to Section 2.2(d) above, the Borrower
shall promptly mail to the Holder a notice setting forth the Conversion Price
after such adjustment and setting forth a statement of the facts requiring such
adjustment.

--------------------------------------------------------------------------------

 

2.3 Most Favored Nations Conversion Right.

(a) At any time after the Effective Date until this Note, including all accrued
and unpaid interest hereon, is paid in full, if the Borrower completes an
offering of equity securities, then, on the date of the consummation by the
Borrower of such offering of the Borrower’s equity securities (which for
purposes of this Section 2.3 includes any securities convertible into or
exercisable for any of the Borrower’s capital stock, but does not include any
Exempt Securities, as defined below), this Note and all accrued and unpaid
interest thereon shall be convertible, in whole or in part and at the option of
the Holder, into a number of shares of such equity securities equal to the
quotient obtained by dividing (i) the principal amount of this Note being
converted by the Holder (together with all accrued and unpaid interest thereon),
by (ii) the price per security at which such equity securities are sold to other
investors in such offering. The Borrower shall notify the Holder of the proposed
closing date of any such offering no less than 3 business days, but no more than
5 business days, prior to such date.

(b) In the event that the Holder elects to convert all or a portion of the Note
pursuant to Section 2.3(a), the Holder shall surrender the Note to the Company,
along with a written notice to the Company, in the manner specified in Section
2.1(c)(ii) hereof, at least 1 day prior to the date on which conversion is
sought to become effective (the “MFN Conversion Date”) that such Holder elects
to convert the Note or a specified portion thereof on the MFNConversion Date,
and such notice shall specify the names (and addresses) in which certificates
for Conversion Shares (as defined below) are to be issued.

(c) If the Note is surrendered for conversion pursuant to Section 2.3(b), then
promptly after the MFN Conversion Date, the Borrower shall deliver or cause to
be delivered to the Holder certificates representing the number of fully paid
and non-assessable shares of the applicable equity securities (the “Conversion
Shares”), into which the Note may be converted. Such conversion shall be deemed
to have been made immediately prior to the close of business on the MFN
Conversion Date, so that the rights of the Holder as a holder of the Note shall
cease with respect to the Note at such time (including, without limitation, the
right to receive the principal amounts of the Note other than in the form of
Conversion Shares), interest shall cease to accrue hereon and the person or
persons entitled to receive the Conversion Shares deliverable upon conversion of
the Note shall be treated for all purposes as having become the record holders
of such Conversion Shares at such time. If this Note shall have been converted
in part, the Borrower shall, at the time of delivery of the certificate or
certificates representing Conversion Shares, deliver to the Holder a new Note
evidencing the rights of the Holder with respect to the remaining principal
amount (and all accrued and unpaid interest thereon), which new Note shall in
all other respects be identical with this Note, or at the request of the Holder,
appropriate notation may be made on this Note and the same returned to the
Holder.

(d) “Exempt Securities” means any shares of Common Stock issued by the Borrower
after the date of issuance of this Note that are: (i) shares issued or issuable
upon the exercise of any warrants or options outstanding as of the original date
of the issuance of this Note (including any warrants issued in connection with
the issuance of the Promissory Notes); (ii) shares of Common Stock or common
stock equivalents issued in connection with a bona-fide strategic transaction,
partnership, joint venture or acquisition or (iii) shares of Common Stock issued
in connection with any stock-based compensation plans of the Borrower, or any
issuance of Common Stock, stock awards or options under, or the exercise of
options granted pursuant to, any Board approved employee stock option or similar
plan for the issuance of options or capital stock of the Borrower.

accelerated and so due and payable; provided, however, that upon the occurrence
of an Event of Default described in Section 3.1(f), without presentment, demand,
protest, or notice, all of which are hereby expressly unconditionally and
irrevocably waived by the Borrower, the outstanding principal balance and
accrued interest hereunder shall be automatically due and payable. In addition,
if an Event of Default shall have occurred and be continuing, the Holder may
exercise or otherwise enforce any one or more of the Holder’s rights, powers,
privileges, remedies and interests under this Note or applicable law and
institute such actions or proceedings in law or equity as it shall deem
expedient for the protection of its rights and may prosecute and enforce its
claims against all assets and property of the Borrower, and in connection with
any such action or proceeding shall be entitled to receive from the Borrower,
payment of the principal amount of this Note plus accrued interest to the date
of payment plus reasonable expenses of collection, including, without
limitation, attorneys' and experts' fees and expenses. No course of delay on the
part of the Holder shall operate as a waiver thereof or otherwise prejudice the
right of the Holder. No remedy conferred hereby shall be exclusive of any other
remedy referred to herein or now or hereafter available at law, in equity, by
statute or otherwise.

ARTICLE IV

MISCELLANEOUS

4.1 Failure or Indulgence Not Waiver. No failure or delay on the part of Holder
hereof in the exercise of any power, right or privilege hereunder shall operate

available rights and remedies, at law or in equity, to such equitable relief,
including but not limited to an injunction restraining any such breach or
threatened breach, without the necessity of showing economic loss and without
