SECTION 7. REGISTRATION OF THE NOTE SHARES AND WARRANT SHARES IN COMPLIANCE WITH
THE SECURITIES ACT.

         7.1 REGISTRATION PROCEDURES AND EXPENSES. The Company shall:

                  (a) the Company shall file with the SEC on Form SB-2, or such
other form as appropriate ("REGISTRATION STATEMENT"), the resale pursuant to
Rule 415 under the Securities Act of the Note Shares and Warrant Shares (the
"REGISTRABLE SECURITIES") by the Purchaser from time to time on the facilities
of any securities market on which shares of the Common Stock are then traded or
in privately-negotiated transactions, and specifically excluding underwritten
offerings;

                  (b) if: (i) a Registration Statement is not filed on or prior
to the 45th day following the Closing Date, or (ii) a Registration Statement is
not declared effective by the SEC on or prior to the 90th day following the
Closing Date, or (iii) after the SEC first declares a Registration Statement
effective, without regard for the reason thereunder or efforts therefore, such
Registration Statement ceases for any reason to be effective and available to
the holders of the Registrable Securities as to all Registrable Securities
registered under such Registration Statement at any time prior to the earlier
date when the Registrable Securities have been sold or may be sold without
volume restrictions pursuant to Rule 144(k) as determined by counsel to the
Company, for more than an aggregate of 20 Trading Days in any twelve month
period (which need not be consecutive) (any such failure or breach being
referred to as an "EVENT," and for purposes of clauses (i) or (ii) the date on
which such Event occurs, or for purposes of clause (iii) the date which such 20
Trading Day period is exceeded, being referred to as "EVENT DATE"), then on each
such Event Date, and on the same day as such Event Date in each subsequent month
until the applicable Event is cured (the Event Date and each such subsequent
date, a "PAYMENT DATE") the Company shall pay to each holder an amount, as
partial liquidated damages and not as a penalty, equal to 2.0% of the Purchase
Price paid by such holder for Securities at closing pursuant to this Securities
Purchase Agreement, such payment being 1% in cash and 1% in Common Stock,
PROVIDED, that in the event the Company fails to deliver such Common Stock by
the 10th Trading Day following such Payment Date, such payment shall be, at the
discretion of the Holder, in all cash. If the Company fails to pay any partial
liquidated damages pursuant to this Section in full within seven days after the
date payable, the Company will pay interest thereon at a rate of 10% per annum
(or such lesser maximum amount that is permitted to be paid by applicable law)
to the holder, accruing daily from the date such partial liquidated damages are
due until such amounts, plus all such interest thereon, are paid in full. The
partial liquidated damages pursuant to the terms hereof shall apply on a daily
pro-rata basis for any portion of a month prior to the cure of an Event, except
in the case of the first Event Date. Liquidated damages payable in Common Stock
pursuant to this section shall be determined by calculating the quotient of the
dollar amount of such liquidated damages divided by either (1) the average of
the closing bid prices of the Common Stock for the five (5) Trading Days prior


                                       7


to the Payment Date and (2) the closing bid price of the Common Stock on the day
preceding the date such Common Stock is delivered pursuant to this SECTION 7(B),
whichever of (1) and (2) yields a greater number of shares;

                  (c) The Company shall, notwithstanding any termination of this
Agreement, indemnify and hold harmless each Purchaser and the officers,
directors, agents and employees of each such Purchaser, to the fullest extent
permitted by applicable law, from and against any and all losses, claims,
damages, liabilities, costs (including, without limitation, reasonable costs of
preparation and reasonable attorneys' fees) and expenses (collectively,
"LOSSES"), as incurred, arising out of or relating to any untrue or alleged
untrue statement of a material fact contained in any Registration Statement, any
Prospectus or any form of prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or relating to any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in light of the circumstances under which
they were made) not misleading, except to the extent, but only to the extent,
that (1) such untrue statements or omissions are based solely upon information
regarding such Purchaser furnished in writing to the Company by such Purchaser
expressly for use therein, or to the extent that such information relates to
such Purchaser or such Purchaser's proposed method of distribution of
Registrable Securities and was reviewed and expressly approved in writing by
such Purchaser expressly for use in the Registration Statement, such Prospectus
or such form of prospectus or in any amendment or supplement thereto or (2) the
use by such Purchaser of an outdated or defective prospectus after the Company
has notified such Purchaser in writing that the Prospectus is outdated or
defective and prior to the receipt by such Purchaser of an advice or an amended
or supplemented prospectus.

                  (d) Each Purchaser shall, severally and not jointly, indemnify
and hold harmless the Company, its directors, officers, agents and employees,
and each person who controls the Company, to the fullest extent permitted by
applicable law, from and against all Losses, as incurred, arising solely out of
or based solely upon: (x) such Purchaser's failure to comply with the prospectus
delivery requirements of the Securities Act or (y) any untrue statement of a
material fact contained in any Registration Statement, any prospectus, or any
form of prospectus, or in any amendment or supplement thereto, or arising solely
out of or based solely upon any omission of a material fact required to be
stated therein or necessary to make the statements therein not misleading to the
extent, but only to the extent that, (1) such untrue statements or omissions are
based solely upon information regarding such Purchaser furnished in writing to
the Company by such Purchaser expressly for use therein, or to the extent that
such information relates to such Purchaser or such Purchaser's proposed method
of distribution of Registrable Securities and was reviewed and expressly
approved in writing by such Purchaser expressly for use in the Registration
Statement, such prospectus or such form of prospectus or in any amendment or
supplement thereto or (2) the use by such Purchaser of an outdated or defective
prospectus after the Company has notified such Purchaser in writing that the
Prospectus is outdated or defective and prior to the receipt by such Purchaser
of an advice or an amended or supplemented prospectus.

                  (e) If any proceeding shall be brought or asserted against any
person entitled to indemnity hereunder (an "INDEMNIFIED PARTY"), such
Indemnified Party shall promptly notify the person from whom indemnity is sought
(the "INDEMNIFYING PARTY") in writing, and the Indemnifying Party shall assume
the defense thereof, including the employment of counsel reasonably satisfactory


                                       8


to the Indemnified Party and the payment of all fees and expenses incurred in
connection with defense thereof; provided, that the failure of any Indemnified
Party to give such notice shall not relieve the Indemnifying Party of its
obligations or liabilities pursuant to this Agreement, except (and only) to the
extent that it shall be finally determined by a court of competent jurisdiction
(which determination is not subject to appeal or further review) that such
failure shall have proximately and materially adversely prejudiced the
Indemnifying Party.

         An Indemnified Party shall have the right to employ separate counsel in
any such proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or
Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; (2) the Indemnifying Party shall have failed promptly to
assume the defense of such proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such proceeding; or (3) the named
parties to any such proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such proceeding.

         All reasonable fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within fifteen (15) Trading Days of written notice thereof to the
Indemnifying Party (regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided, that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder).

   The indemnity agreements contained in this SECTION 7 are in addition to any
liability that the Indemnifying Parties may have to the Indemnified Parties.

                  (f) prepare and file with the Commission such amendments and
supplements to the Registration Statement and the prospectus used in connection
therewith as may be necessary to keep the Registration Statement effective until
the earlier of (i) the second anniversary of the Closing Date, (ii) the date on
which the Purchaser may sell all the Note Shares or Warrant Shares then held by
the Purchaser within a three-month period in accordance with Rule 144 under the
Securities Act ("RULE 144"), or (iii) such time as all the Note Shares and
Warrant Shares which the Purchaser has a right to acquire have been sold
pursuant to a registration statement;


                                       9

                                       10


the extent not otherwise included in clauses (i) through (xv) of this Section,
all Proceeds, products, substitutions, accessions, rents and profits of or in
respect of any of the foregoing (the "COLLATERAL") of the Company on the same
terms and conditions as the Security Agreement (the "SECURITY INTEREST") and
that the Company and the Purchaser shall have the same rights, duties, and
obligations as if Purchaser was a party to the Security Agreement; PROVIDED
THAT: (a) the Purchaser shall not be considered a "Secured Party" for purposes

Agreement, have been converted or paid in full, (b) the Purchasers shall not
have a right to prevent the Company from granting further security interests,

                  (b) The Security Interest, this Agreement and the transactions
contemplated hereby are intended to comply with the requirements for
subordination under, and to the fullest extent necessary to so comply are
expressly subordinated to, the security interest granted to the holders of the
Promissory Notes (the "EOIR NOTES"), dated June 29, 2004, made by EOIR pursuant
to a Security Agreement, dated June 29, 2004, between EOIR and the holders of
the EOIR Notes, (the "EOIR SECURITY AGREEMENT"), without limiting the generality
of the foregoing, the Security Interest created by this Agreement is junior to
and subordinated to the Liens (as defined in the EOIR Security Agreement) to the
