sale price for the Common Stock on such day on the principal securities exchange
on which the Common Stock is listed or admitted to trading or if no such sale
takes place on such date, the average of the closing bid and asked prices

prices in the over-the-counter market as furnished by any NASD member firm

                                   ARTICLE II

                              Exercise of Warrants

II.1 Method of Exercise. The Warrants represented hereby may be exercised by the
holder hereof, in whole or in part, at any time and from time to time on or
after the date hereof until 5:00 p.m., Houston, Texas time, on the Expiration
Date. To exercise the Warrants, the holder hereof shall deliver to the Company,
at the Warrant Office designated herein, (i) a written notice in the form of the
Subscription Notice attached as an exhibit hereto, stating therein the election
of such holder to exercise the Warrants in the manner provided in the
Subscription Notice; (ii) payment in full of the Exercise Price (A) in cash or
by bank check for all Warrant Shares purchased hereunder, or (B) through a
"cashless" or "net-issue" exercise of each such Warrant ("Cashless Exercise");
the holder shall exchange each Warrant subject to a Cashless Exercise for that
number of Warrant Shares determined by multiplying the number of Warrant Shares
issuable hereunder by a fraction, the numerator of which shall be the difference
between (x) the Market Price and (y) the Exercise Price for each such Warrant,
and the denominator of which shall be the Market Price; the Subscription Notice
shall set forth the calculation upon which the Cashless Exercise is based, or
(C) a combination of (A) and (B) above; and (iii) these Warrants. The Warrants
shall be deemed to be exercised on the date of receipt by the Company of the
Subscription Notice, accompanied by payment for the Warrant Shares and surrender
of these Warrants, as aforesaid, and such date is referred to herein as the
"Exercise Date". Upon such exercise, the Company shall, as promptly as
practicable and in any event within five business days, issue and deliver to
such holder a certificate


                                       2

<PAGE>

or certificates for the full number of the Warrant Shares purchased by such
holder hereunder, and shall, unless the Warrants have expired, deliver to the
holder hereof a new Warrant representing the number of Warrants, if any, that
shall not have been exercised, in all other respects identical to these
Warrants. As permitted by applicable law, the person in whose name the
certificates for Common Stock are to be issued shall be deemed to have become a
holder of record of such Common Stock on the Exercise Date and shall be entitled
to all of the benefits of such holder on the Exercise Date, including without
limitation the right to receive dividends and other distributions for which the
record date falls on or after the Exercise Date and to exercise voting rights.

II.2 Expenses and Taxes. The Company shall pay all expenses and taxes
(including, without limitation, all documentary, stamp, transfer or other
transactional taxes) other than income taxes attributable to the preparation,
issuance or delivery of the Warrants and of the shares of Common Stock issuable
upon exercise of the Warrants.

II.3 Reservation of Shares. The Company shall reserve at all times so long as
the Warrants remain outstanding, free from preemptive rights, out of its
authorized but unissued shares of Common Stock, solely for the purpose of
effecting the exercise of the Warrants, a sufficient number of shares of Common
Stock to provide for the exercise of the Warrants.

II.4 Valid Issuance. All shares of Common Stock that may be issued upon exercise
of the Warrants will, upon issuance by the Company, be duly and validly issued,
fully paid and nonassessable and free from all taxes, liens and charges with
respect to the issuance thereof and, without limiting the generality of the
foregoing, the Company shall take no action or fail to take any action which
will cause a contrary result (including, without limitation, any action that
would cause the Exercise Price to be less than the par value, if any, of the
Common Stock).

II.5 Loan Agreement. The Warrants represented hereby were issued on conjunction
with a Loan Agreement dated around April 5, 2002 as amended from time to time
(the "Loan Agreement") between the Company and the Holder. The Holder shall be
entitled to the rights to registration under the Securities Act and any
applicable state securities or blue sky laws to the extent set forth in the
registration rights provision found in the Loan Agreement. The terms of the
registration rights provisions are hereby incorporated herein for all purposes
and shall be considered a part of this Warrant as if they had been fully set
forth herein.

II.6 Acknowledgment of Rights. At the time of the exercise of the Warrants in
accordance with the terms hereof and upon the written request of the holder
hereof, the Company will acknowledge in writing its continuing obligation to
afford to such holder any rights (including, without limitation, any right to
registration of the Warrant Shares) to which such holder shall continue to be
entitled after such exercise in accordance with the provisions of these
Warrants; provided, however, that if the Holder hereof shall fail to make any
such request, such failure shall not affect the continuing obligation of the
Company to afford to such Holder any such rights.

II.7 No Fractional Shares. The Company shall not be required to issue fractional
shares of Common Stock on the exercise of these Warrants. If more than one
Warrant shall be presented for exercise at the same time by the same holder, the
number of full shares of Common Stock which shall be issuable upon such exercise
shall be computed on the basis of the aggregate number of


                                       3

<PAGE>

whole shares of Common Stock purchasable on exercise of the Warrants so
presented. If any fraction of a share of Common Stock would, except for the
provisions of this Section, be issuable on the exercise of this Warrant, the
Company shall pay an amount in cash calculated by it to be equal to the Market
Price of one share of Common Stock at the time of such exercise multiplied by
such fraction computed to the nearest whole cent.

                                  ARTICLE III

                                    Transfer

III.1 Warrant Office. The Company shall maintain an office for certain purposes
specified herein (the "Warrant Office"), which office shall initially be the
Company's offices at 111 Presidential Boulevard, Suite 158-A, Bala Cynwyd, PA
19004 and may subsequently be such other office of the Company or of any
transfer agent of the Common Stock in the continental United States as to which
written notice has previously been given to the Holder. The Company shall
maintain, at the Warrant Office, a register for the Warrants in which the
Company shall record the name and address of the Person in whose name these
Warrants has been issued, as well as the name and address of each permitted
assignee of the rights of the registered owner hereof.

III.2 Ownership of Warrants. The Company may deem and treat the Person in whose
name the Warrants are registered as the holder and owner hereof until provided
with notice to the contrary. The Warrants may be exercised by an assignee for
the purchase of Warrant Shares without having new Warrants issued.

III.3 Restrictions on Transfer of Warrants. These Warrants may be transferred,
in whole or in part, by the Holder. The Company agrees to maintain at the
Warrant Office books for the registration and transfer of the Warrants. The
Company, from time to time, shall register the transfer of the Warrants in such
books upon surrender of this Warrant at the Warrant Office properly endorsed or
accompanied by appropriate instruments of transfer and written instructions for
transfer. Upon any such transfer and upon payment by the holder or its
transferee of any applicable transfer taxes, new Warrants shall be issued to the
transferee and the transferor (as their respective interests may appear) and the
surrendered Warrants shall be cancelled by the Company. The Company shall pay
all taxes (other than securities transfer taxes or income taxes) and all other
expenses and charges payable in connection with the transfer of the Warrants
pursuant to this Section.

III.4 Compliance with Securities Laws. Subject to the terms of the Registration
Rights Agreement and notwithstanding any other provisions contained in these
Warrants, the Holder understands and agrees that the following restrictions and
limitations shall be applicable to all Warrant Shares and to all resales or
other transfers thereof pursuant to the Securities Act:

         III.4.1 The holder hereof agrees that the Warrant Shares may not be
sold or otherwise transferred unless the Warrant Shares are registered under the
Securities Act and applicable state securities or blue sky laws or are exempt
therefrom.

         III.4.2 A legend in substantially the following form will be placed on
the certificate(s) evidencing the Warrant Shares:


                                       4

<PAGE>

                  "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
         "SECURITIES ACT"), OR ANY OTHER APPLICABLE SECURITIES LAW AND,
         ACCORDINGLY, THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY NOT BE
         RESOLD, PLEDGED, OR OTHERWISE TRANSFERRED, EXCEPT PURSUANT TO AN
         EFFECTIVE REGISTRATION STATEMENT UNDER, OR IN A TRANSACTION EXEMPT FROM
         REGISTRATION UNDER, THE SECURITIES ACT AND IN ACCORDANCE WITH ANY OTHER
         APPLICABLE SECURITIES LAWS."

                                   ARTICLE IV

                                  Anti-Dilution

         IV.1 If and whenever any Additional Common Stock (as herein defined)
shares shall be issued by the Company (the "Stock Issue Date") for a
consideration per share less than the Exercise Price, then in each such case the
initial Exercise Price shall be reduced to a new Exercise Price in an amount
equal to the consideration per share received by the Company for the additional
shares of Common Stock then issued and the number of shares issuable to Holder
upon conversion shall be proportionately increased; and, in the case of shares
issued without consideration, the initial Exercise Price shall be reduced in
amount and the number of shares issued upon conversion shall be increased in an
amount so as to maintain for the Holder the right to exercise into shares equal
in amount to the same percentage interest in the Common Stock of the Company as
existed for the Holder immediately preceding the Stock Issue Date.

         IV.2 Sale of Shares: In case of the issuance of Additional Common Stock
for a consideration part or all of which shall be cash, the amount of the cash
consideration therefore shall be deemed to be the amount of the cash received by
Company for such shares, after any compensation or discount in the sale,
underwriting or purchase thereof by underwriters or dealers or others performing
similar services or for any expenses incurred in connection therewith. In case
of the issuance of any shares of Additional Common Stock for a consideration
part or all of which shall be other than cash, the amount of the consideration
therefore, other than cash, shall be deemed to be the then fair market value of
the property received as determined by an investment banking firm selected by
Lender.

         IV.3 Reclassification of Shares: In case of the reclassification of
securities into shares of Common Stock, the shares of Common Stock issued in
such reclassification shall be deemed to have been issued for a consideration
other than cash. Shares of Additional Common Stock issued by way of dividend or
other distribution on any class of stock of the Company shall be deemed to have
been issued without consideration.

         IV.4 Split up or Combination of Shares: In case issued and outstanding
shares of Common Stock shall be subdivided or split up into a greater number of
shares of the Common Stock, the Exercise Price shall be proportionately
decreased, and in case issued and outstanding shares of Common Stock shall be
combined into a smaller number of shares of Common Stock, the Exercise


                                       5

<PAGE>

Price shall be proportionately increased, such increase or decrease, as the case
may be, becoming effective at the time of record of the split-up or combination,
as the case may be.

         IV.5 Exceptions: The term "Additional Common Stock" herein shall mean
in the most broadest sense all shares of Common Stock hereafter issued by the
Company (including, but not limited to Common Stock held in the treasury of the
Company and common stock purchasable via derivative security or option on the
date of such grant), except Common Stock issued upon the exercise of this
warrant or the Convertible Notes.

         IV.6 In the event of distribution to all Common Stock holders of any
stock, indebtedness of the Company or assets or other rights to purchase
securities or assets, then, after such event, the Exercise Price reduced to so
as to entitle the Holder to the economic interest he had immediately prior to
the occurrence of such event.

         IV.7 In case of any capital reorganization, reclassification of the
stock of the Company (other than a change in par value or as a result of a stock
dividend, subdivision, split up or combination of shares), the Exercise Price
reduced to so as to entitle the Holder to the economic interest he had
immediately prior to the occurrence of such event. The provisions of these
foregoing sentence shall similarly apply to successive reorganizations,
reclassifications, consolidations, exchanges, leases, transfers or other
dispositions or other share exchanges.

         IV.8 Notice of Adjustment. (A) In the event the Company shall propose
to take any action which shall result in an adjustment in the Exercise Price,
the Company shall give notice to the Holder, which notice shall specify the
record date, if any, with respect to such action and the date on which such
action is to take place. Such notice shall be given on or before the earlier of
10 days before the record date or the date which such action shall be taken.
Such notice shall also set forth all facts (to the extent known) material to the
effect of such action on the Exercise Price and the number, kind or class of
shares or other securities or property which shall be deliverable or purchasable
upon the occurrence of such action or deliverable upon exercise of this warrant
(B) Following completion of an event wherein the Exercise Price shall be
adjusted, the Company shall furnish to the Holder a statement, signed by an
authorized officer of the Company of the facts creating such adjustment and
specifying the resultant adjusted Exercise Price then in effect.

                                   ARTICLE V

                                  Miscellaneous

         V.1 Entire Agreement. These Warrants, together with the Loan Agreement,
contain the entire agreement between the holder hereof and the Company with
respect to the Warrant Shares purchasable upon exercise hereof and the related
transactions and supersedes all prior arrangements or understandings with
respect thereto.

         V.2 Governing Law. This warrant shall be governed by and construed in
accordance with the laws of the State of Texas in the courts located in Dallas,

         V.3 Waiver and Amendment. Any term or provision of these Warrants may
be waived at any time by the party which is entitled to the benefits thereof and
any term or provision of these Warrants may be amended or supplemented at any
time by agreement of the holder hereof and the Company, except that any waiver
of any term or condition, or any amendment or supplementation, of these Warrants
shall be in writing. A waiver of any breach or failure to enforce any of the
terms or conditions of these Warrants shall not in any way effect, limit or
waive a party's rights hereunder at any time to enforce strict compliance
thereafter with every term or condition of these Warrants.

         V.4 Illegality. In the event that any one or more of the provisions
contained in this Warrant shall be determined to be invalid, illegal or
unenforceable in any respect for any reason, the validity, legality and
enforceability of any such provision in any other respect and the remaining
provisions of these Warrants shall not, at the election of the party for whom
the benefit of the provision exists, be in any way impaired.

         V.5 Copy of Warrant. A copy of these Warrants shall be filed among the
records of the Company.

         V.6 Notice. Any notice or other document required or permitted to be
given or delivered to the holder hereof shall be in writing and delivered at, or
sent by certified or registered mail to such holder at, the last address shown
on the books of the Company maintained at the Warrant Office for the
registration of these Warrants or at any more recent address of which the holder
hereof shall have notified the Company in writing.

         V.7 Limitation of Liability; Not Stockholders. No provision of these
Warrants shall be construed as conferring upon the holder hereof the right to
vote, consent, receive dividends or receive notices (other than as herein
expressly provided) in respect of meetings of stockholders for the election of
directors of the Company or any other matter whatsoever as a stockholder of the
Company. No provision hereof, in the absence of affirmative action by the holder
hereof to purchase shares of Common Stock, and no mere enumeration herein of the
rights or privileges of the holder hereof, shall give rise to any liability of
such holder for the purchase price of any shares of Common Stock or as a
stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.

         V.8 Exchange, Loss, Destruction, etc. of Warrant. Upon receipt of
evidence reasonably satisfactory to the Company of the loss, theft, mutilation
or destruction of these Warrants, and in the case of any such loss, theft or
destruction upon delivery of an appropriate affidavit in such form as shall be
reasonably satisfactory to the Company and include reasonable indemnification of
the Company, or in the event of such mutilation upon surrender and cancellation
of these Warrants, the Company will make and deliver new Warrants of like tenor,
in lieu of such lost, stolen, destroyed or mutilated Warrants. Any Warrants
issued under the provisions of this Section in lieu of any Warrants alleged to
be lost, destroyed or stolen, or in lieu of any mutilated Warrants, shall
constitute an original contractual obligation on the part of the Company. These
Warrants shall be promptly canceled by the Company upon the surrender hereof in
connection with any exchange or replacement. The Company shall pay all taxes
(other than securities transfer taxes or income taxes) and all other expenses
and charges payable in connection with the preparation, execution and delivery
of Warrants pursuant to this Section.
