July, 2000, by and between Open-i Media, Inc., a New York corporation ("Seller"
or the "Company"), and SIGA Technologies, Inc., a Delaware corporation
("Purchaser").

                              W I T N E S S E T H:

      WHEREAS, Seller desires to sell to Purchaser, and Purchaser desires to
purchase from Seller, one million one hundred forty-three thousand (1,143,000)
shares of Series A Preferred stock, par value $0.001 per share, of Seller, all
on the terms and conditions hereinafter set forth.

      NOW, THEREFORE, in consideration of the premises and mutual
representations, warranties and covenants contained herein, and intending to be
legally bound hereby, the parties agree as follows:

      1. Purchase of Shares. (a) Seller hereby agrees to sell to Purchaser, and
Purchaser hereby agrees to purchase from Seller, one million one hundred
forty-three thousand (1,143,000) shares of Series A Preferred stock of Seller,
par value $0.001 per share, (the "Purchased Shares"), for and in consideration
of the sum of One Hundred Seventy Thousand Dollars ($170,000) in cash paid
concurrently herewith in immediately available funds, plus the number of shares
of Purchaser common stock as shall equal One Hundred Eighty Thousand Dollars
($180,000) (the "SIGA Shares") as calculated based on the average closing sale
price of Purchaser's common stock on the Nasdaq Small Cap Market on the five (5)
trading dates preceding the Closing Date (as hereinafter defined), plus all
right, title, and interest in and to that certain computer program identified as
"Peerfinder" as set forth in the Assignment of Intellectual Property Agreement
attached hereto as Exhibit A, including appropriate assignments (the "Assets").
The rights, privileges, preferences and other terms of the Purchased Shares are
set forth in the Restated Certificate of Incorporation of the Company (the
"Restated Certificate of Incorporation"), a copy of which is attached hereto as
Exhibit B.

            (b) No later than September 30, 2000, subject to any comments of the
Securities and Exchange Commission (the "SEC"), Purchaser shall cause a
registration statement under the Securities Act of 1933, as amended (the
"Securities Act") on Form S-3 (or on any successor form to Form S-3 regardless
of its designation) covering the SIGA Shares to become effective under the
Securities Act, and Purchaser shall use its reasonable best efforts to keep such
registration effective in accordance with applicable regulations for a period of
five (5) months from the date on which the SEC declares such registration
statement effective until the SIGA Shares have been sold pursuant to such
registration statement.

            (c) Title to the Assets shall be conveyed to Seller, on the Closing
Date (as hereinafter defined), free and clear of all liens and encumbrances.
Purchaser shall assume no obligations or liabilities of Seller whatsoever,
whether known or unknown, matured or unmatured, absolute or contingent, whether
relating to the Assets or otherwise.

<PAGE>

            (d) The closing of the purchase and sale of the Purchased Shares
hereunder (the "Closing") shall take place at the offices of Camhy Karlinsky &
Stein LLP, 1740 Broadway, New York, New York at 10:00 am on July 7, 2000 or at
such other time and place as the Company and Purchaser may agree in writing (the
"Closing Date").

      2. Board Positions. (a) Until (i) such time as Purchaser owns less than
five percent (5%) of Seller's stock on a fully diluted basis, or (ii) the date
of the consummation of an initial public offering of Seller's stock, Seller
shall have the obligation to cause Purchaser's representative ("Purchaser's
Director") to be appointed to Seller's board of directors. Seller and Purchaser
agree that Purchaser's Director shall be either Judson Cooper, Josh Schein, Dave
Kaufman or such other person as shall be mutually acceptable to Seller and
Purchaser. The number of directors on the Company's Board of Directors shall be
initially set at five (5). To determine when Purchaser owns less than five
percent (5%) of Seller's stock for purposes of this Section 2(a) the total
number of shares of common stock issued or issuable to Purchaser shall be
divided by (b) the total number of issued and outstanding shares of common and
preferred stock of Seller, which number shall not include any capital stock
issuable upon exercise of outstanding options or warrants of Seller.

            (b) Any board action approving a Below Market Transaction shall
require the affirmative vote of Purchaser's Director. A "Below Market
Transaction" as defined herein, shall mean either (i) a sale of all or
substantially all the assets of the Corporation; or (ii) a merger or
consolidation involving the Company in which the Company is not the surviving
entity and in which the shareholders of the Company immediately preceding such
transaction do not own at least fifty percent (50%) of the total equity interest
in the resulting entity after such transaction is closed, and in either (b)(i)
or (b)(ii) above, the valuation of Seller is less than ten million dollars
($10,000,000).

      3. Seller Representations and Warranties. Seller hereby represents and

            3.1 Organization and Standing. The Company is a corporation duly
organized, validly existing and is in good standing under the laws of the State
of New York, and has the requisite corporate power and authority to own its

the Company has no subsidiaries or direct or indirect ownership interest in any
firm, corporation, partnership, joint venture, association or other business
organization. The Company is qualified to do business and is in good standing as
a foreign corporation in every jurisdiction in which its ownership of property
or conduct of business requires it so to be qualified and in which the failure
to so qualify would result in any change or effect that is materially adverse (a
"Material Adverse Effect") to the business, properties, results of operations or
financial condition taken as a whole (collectively, "Condition") of the Company.
The Company has the requisite corporate power and authority to execute and
deliver this Agreement and to issue the Purchased Shares and the common stock
into which the Purchased Shares are convertible (the "Conversion Shares") and to
otherwise perform its obligations under this Agreement. The copies of the

Purchaser prior to the execution of this Agreement are true and complete copies
of

Company.

            3.3 Events Subsequent to the Balance Sheet Date. Since the Balance

            3.4 Tax Returns. All required federal, state or local tax returns or
appropriate extension requests of the Company have been filed, and all federal,
state and local taxes required to be paid in accordance with such returns have
been paid or due provision for the payment thereof has been made. The Company

            3.5 Title to Properties and Encumbrances. Except as set forth on

not own any real property. The Company has not received any notice of any action
or proceeding under any building, zoning or other ordinance, law or regulation.
With respect to the property and assets it leases, the Company is in compliance
with such leases, except where the failure to be so in compliance would not have
a Material Adverse Effect on the Condition of the Company, and to its knowledge,
holds a valid leasehold interest free from any liens, claims or encumbrances.

            3.6 Litigation. There are no legal actions, suits, arbitrations or
other legal, administrative or governmental proceedings or investigations
pending or, to the knowledge of the Company, threatened against the Company or
its properties, assets or business, and neither the Company nor any of its
officers has knowledge of any facts which would be reasonably expected to result
in or form the basis for any such action, suit or other proceeding that would
have a Material Adverse Effect on the Condition of the Company. The Company is
not in default with respect to any judgment, order or decree of any court or any
governmental agency or instrumentality known to the Company.

            3.7 Compliance with Other Instruments. The Company is not in
violation or default of any term in its Restated Certificate of Incorporation or
Bylaws, or of any term contained in any mortgage, indenture, agreement,
instrument or contract to which it is a party, except for such violations as
would not have a Material Adverse Effect on the Condition of the Company. To its
knowledge, the Company is not in violation of any order, statute, rule or
regulation applicable to the Company, except for such violations as would not
have a Material Adverse Effect on the Condition of the Company. Neither the
execution, delivery and performance of this Agreement nor any other agreement
contemplated hereby, nor, assuming the representations and warranties made by
Purchaser in Article 4 are true and correct, the issuance of the Purchased
Shares, will result in any such violation or be in conflict with or constitute a
default under any such term, or result in the creation of any mortgage, pledge,
lien, encumbrance or charge upon any of the properties or assets of the Company.

            3.8 Purchased Shares and Conversion Shares. The Purchased Shares,
when issued in accordance with the terms of this Agreement, will be validly
issued, fully paid, and non-assessable and will be free and clear of all
pledges, liens, encumbrances and restrictions, other than as set forth herein or

state securities laws. The Conversion Shares issuable upon conversion of the
Purchased Shares have been reserved for issuance and, when so issued, will be

and delivery of the Purchased Shares and the Conversion Shares will not, under
current laws and regulations, require compliance with the prospectus delivery or

representations and warranties of Purchaser contained in Article 4 hereof.

            3.10 Patents, Trademarks, and Trade Secrets. There are no pending
or, to the Company's knowledge, threatened claims against the Company alleging
that the Company's business, as conducted or as proposed to be conducted,
infringes or conflicts with the rights of others under patents, service marks,
trade names, trademarks, copyrights, trade secrets or other proprietary rights
("Intellectual Property Rights"). To the knowledge of the Company, the Company's
business as now conducted does not, and as proposed to be conducted will not,
infringe or conflict with the rights of others, including Intellectual Property
Rights. The Company owns, or possesses sufficient legal rights to use, all
Intellectual Property Rights and other rights necessary for the operation of its
business as now conducted and as proposed to be conducted without conflict or
infringement against the rights of others. Except as set forth in Schedule 3.10,
there are no outstanding options, licenses, or agreements of any kind relating
to the foregoing, nor is the Company bound by or a party to any options,
licenses or agreements of any kind with respect to the Intellectual Property
Rights of any other person or entity, except for those arising from
"off-the-shelf" commercial software. To the knowledge of the Company the Company
has not violated or, by conducting its business as proposed, would not violate
any of the Intellectual Property Rights of any other person or entity. To the
knowledge of the Company, no employee or consultant of the Company owns any
Intellectual Property Rights which are directly or indirectly competitive with
those owned or to be used by the Company or derived from or in connection with
the conduct of the Company's business. The Company is not aware of any violation
or infringement by a third party of any of the Company's Intellectual Property
Rights. The Company has taken and will take reasonable security measures to
protect the secrecy, confidentiality and value of all trade secrets useful in
the conduct of its business.

million (6,000,000) shares of Common Stock were issued and outstanding, and two
million (2,000,000) shares of Series A Preferred Stock were issued and
outstanding. The Purchased Shares will, at the time of issuance represent twelve
and one half percent (12.5%) of the issued and outstanding capital stock of the
Company on a fully diluted basis. All of the outstanding shares of the Company's
capital stock were duly authorized and

                                       5

compliance with all applicable federal and state securities laws. Except as set
forth on Schedule 3.11 attached hereto, prior to the Closing, there are no
agreements among the Company's stockholders with respect to the voting or
transfer of the Company's capital stock or with respect to other material
aspects of the Company's affairs. As of the date of this Agreement there are no
convertible securities, warrants, options or other agreements or arrangements
(collectively, "Purchase Rights") under which the Company is or may be obligated
to issue shares of its capital stock or any Purchase Rights. No holder of any
security of the Company is entitled to any preemptive or similar rights to
purchase any securities proposed to be sold by the Company, except as provided
in this Agreement.

authorized by the requisite corporate action and has been duly executed and
delivered by an authorized officer of the Company, and is a valid and binding
obligation of the Company enforceable in accordance with its terms, except as
such enforceability may be limited by bankruptcy, insolvency, moratorium,

rights generally and by limitations on the enforcement of the remedy of specific
performance and other equitable remedies. The requisite corporate action
necessary to the authorization, creation, issuance and delivery of the Purchased
Shares and the Conversion Shares will be taken by the Company prior to the
Closing.

            3.14 Insurance Coverage. There are in full force policies of
insurance issued by insurers of recognized responsibility insuring the Company
and its properties and business against loss, damage, fire or other risks,

any automobiles, trucks, or other vehicles or other facilities. The Company
maintains all worker's compensation or similar insurance as may be required
under the laws of any state or jurisdiction in which it may be engaged in
business.

            3.15 No Brokers or Finders. No person has or will have, as a result
of any act or omission of the Company, any right, interest or valid claim
against the Company or Purchaser for any commission, fee or other compensation
as a finder or broker in connection with the transactions contemplated by this
Agreement. The Company will indemnify and hold Purchaser harmless against any
and all liability solely with respect to any such commission, fee or other
compensation.

            3.16 Disclosure. The Company has fully provided Purchaser with the
information which Purchaser has requested for deciding whether to purchase the
Purchased Shares. No representation or warranty by the Company in this Agreement
or the exhibits or schedules attached hereto applicable to it contains or will
contain any untrue statement of a material fact or omits or will omit to state a
material fact necessary to make the statements contained therein or herein not
misleading in light of the circumstances under which they were made. Any
disclosure made under any section of this Article 3 shall be deemed to have been
made under all other sections of this Article 3 to which such disclosure
reasonably relates.

            3.17 Registration Rights. Except as set forth on Schedule 3.17,
other than under this Agreement, the Company has not agreed to register under
the Securities Act any of its authorized or outstanding securities.

are or will be required in order to comply with any such existing statute, law
or regulation.

            3.20 Licenses and Permits. The Company possesses from the
appropriate agency, commission, board or government body or authority, whether
state, local or federal, all licenses, permits, authorizations, approvals,

has any direct or indirect interest (a) in any person which does business with
the Company, (b) in any material property, asset or right which is used by the
Company in the conduct of its business, or (c) in any contractual relationship
with the Company, other than as an employee. For the purpose of this Section

agreement or any agreement or restriction of any kind that would impede in any
way the ability of such employee to carry out fully all activities of such

            3.2 Nondistributive Intent. The Seller is acquiring the SIGA Shares
to be issued pursuant to Section 1 hereof for its own account, for investment
and not with a view to the distribution thereof. Seller will not sell or
otherwise dispose of such shares without registration under the Securities Act,
or an exemption therefrom.

            3.25 Other Representations Ineffective. Seller shall not be liable
or bound in any manner by representations, warranties, covenants, agreements or

specifically set forth in this Agreement or the Schedules hereto or in any
certificate or other agreement, document or instrument delivered pursuant to the
provisions of this Agreement.

regard to any notices of sales required to be filed with the SEC pursuant to
Regulation D under the Securities Act, or such post-Closing filings as may be
required under the applicable state securities laws, which will be timely filed
within the applicable periods therefor. Under the circumstances contemplated
hereby, the offer, issuance, sale and delivery of the SIGA Shares will not,

<PAGE>

registration requirements of the Securities Act, assuming the accuracy of the
representations and warranties of Seller contained in Article 3 hereof.

            4.5 Assets. Purchaser has and the Company will receive at Closing,
good and marketable title to the Assets free and clear of all mortgages,
pledges, liens, charges, restrictions, easements and other encumbrances. There
are no pending or, to the Company's knowledge, threatened claims against
Purchaser alleging that the Assets infringe or conflict with the rights of
others under patents, service marks, trade names, trademarks, copyrights, trade
secrets or other proprietary rights. To the knowledge of Purchaser, the
Company's use of the Assets as proposed to be conducted will not, infringe or
conflict with the rights of others. To the knowledge of Purchaser, no employee
or consultant of Purchaser owns any intellectual property rights which are
directly or indirectly competitive with the Assets. Purchaser is not aware of
any violation or infringement by a third party of any of the Assets. Purchaser
has taken and will take reasonable security measures to protect the secrecy,
confidentiality and value of the Assets.

            4.6 No Brokers or Finders. Purchaser has not authorized any person
to act as broker, finder or in any other similar capacity in connection with the
transactions described in this Agreement and the negotiations leading to it in
such manner as to give rise to any valid claim against Seller for any broker's
or finder's fee or similar compensation.

            4.7 Nondistributive Intent. Purchaser is acquiring the Purchased
Shares solely for Purchaser's own account for investment and not with a view to
resale or distribution thereof, in whole or in part, and Purchaser has no
present or contemplated intention, agreement, understanding or arrangement to
sell, assign, transfer, hypothecate or otherwise dispose of all or any part of
the Purchased Shares.

            4.8 Limitations on Transfer. Purchaser understands that the
Purchased Shares have not been registered under the Securities Act and state
securities laws (the "Securities Laws") and are offered and sold in reliance
upon an exemption from the registration requirements of the Securities Act and
exemptions available under applicable state securities laws and that, in that
regard, Seller is relying on the representations and warranties made by
Purchaser herein.

            4.9 Restricted Securities. Purchaser understands that the Purchased
Shares may not be sold, transferred, hypothecated or otherwise disposed of

defined below, holders of Series A Preferred shall be entitled to receive from

Corporation's stockholders, prior and in preference to any distribution to the
holders of Common Stock or any other series of Preferred Stock, an amount per
share equal to the original Series A Preferred issue price (the "Series A
Liquidation Preference"). After the payment in full of the Series A Liquidation
Preference, any remaining assets of the Corporation legally available for
distribution to the Corporation's stockholders shall be distributed to the
holders of Common Stock, pro rata in accordance with the number of shares of
Common Stock held.

            (b) In the event the assets and funds legally available for
distribution to the holders of Series A Preferred are not sufficient to permit
the payment of the full Series A Liquidation Preference to each holder of Series
A Preferred, then the amount legally available for distribution to the holders
of Series A Preferred shall be allocated among the holders of Series A Preferred
pro rata in accordance with the maximum amounts which such holders would have
received if the assets and funds had been sufficient to permit the payment of
the full amount of the Series A Liquidation Preference.

            (c) As used herein, the term "Liquidation Event" shall mean any of
the following events: (i) any sale of all or substantially all of the assets of
the Corporation, or (ii) any liquidation, dissolution or winding up of the
Corporation.

convertible, at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the Corporation or any transfer agent
for such stock, into such number of fully paid and nonassessable shares of
Common Stock as is determined by dividing (i) $1.00 by the Series A Conversion
Price, determined as hereafter provided, in effect on the date the certificate
is surrendered for conversion. The initial Series A Conversion Price shall be
$1.00. The Series A Conversion Price shall be subject to adjustment as set forth
in subsection 2(d) below.

            (b) Automatic Conversion. Each share of Series A Preferred shall
automatically be converted into shares of Common Stock at the Series A
Conversion Price then in effect immediately prior to the occurrence of any of
the following events (each an "Automatic Conversion Event"): (i) any merger or
consolidation of the Corporation with or into another business entity,
regardless of whether or not the Corporation is the surviving entity, provided
that (A) if the Corporation is not the surviving entity, and (B) the
shareholders of the Corporation immediately preceding such transaction do not
own at least fifty percent (50%) of the total equity interest in the resulting
entity after such transaction is closed, and (C) the valuation of the
Corporation in the transaction is less than ten million dollars ($10,000,000),
the affirmative vote of each of the directors designated by the holders of
Series A Preferred (each a "Series A Designated Director") pursuant to those
certain Stock Purchase Agreements between the holders of Series A Preferred

Corporation's securities.

            (c) Mechanics of Conversion. Except in the case of an automatic
conversion, before any holder of Series A Preferred shall be entitled to convert
the same into shares of

                                      -3-

Common Stock, such holder shall surrender the certificate or certificates
therefor, duly endorsed, at the office of the Corporation or of any transfer
agent for the Series A Preferred and shall give written notice to the
Corporation at its principal corporate office of the election to convert the
same and shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued. The Corporation shall,
as soon as practicable thereafter, issue and deliver at such office to such
holder, or to the nominee or nominees of such holder, a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled. Such conversion shall be deemed to have been made immediately prior
to the close of business on the date of such surrender of the shares to be
converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock as of such date. The
automatic conversion of shares of Series A Preferred pursuant to subsection 2(b)
shall be deemed to be effective upon the happening of the event upon which such
automatic conversion is contingent, whether or not the holder thereof has
surrendered the certificate therefor and, upon such automatic conversion, the
shares of Series A Preferred shall cease to be outstanding and the holders
thereof shall be entitled only to receive certificates evidencing the Common
Stock issued upon such conversion against delivery of the certificates
evidencing such shares of Series A Preferred. The Corporation shall give written
notice of any automatic conversion resulting from the happening of an Automatic
Conversion Event to all holders of Series A Preferred within five (5) business
days of the occurrence of either: (i) the consummation of the Automatic
Conversion Event or (ii) the receipt of knowledge by any officer of the
Corporation of the consummation of an Automatic Conversion Event. Each holder of
shares of Series A Preferred which have been automatically converted as provided
herein shall surrender the certificate or certificates evidencing such shares of
Series A Preferred, duly endorsed, at the office of the Corporation or of any
transfer agent for the Series A Preferred and the person or persons entitled to
receive shares of Common Stock issuable upon such automatic conversion shall be
treated for all purposes as the record holder or holders of such shares of
Common Stock as of the date such certificate or certificates are so surrendered.
The Corporation shall, as soon as practicable thereafter, issue and deliver at
such office to such holder, or to the nominee or nominees of such holder, a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled.

            (d) Adjustments to Series A Conversion Price for Diluting Issues.

                  (i) Special Definitions. For purposes of this Section 2(d),
the following definitions shall apply:

                              (A) "Option" shall mean rights, options or
warrants to subscribe for, purchase or otherwise acquire Common Stock or
Convertible Securities (as defined herein) (such excluded options and shares,
the "Reserved Option Shares").

                              (B) "Convertible Securities" shall mean any
evidences of indebtedness, shares or other securities (other than the Reserved
Option Shares) directly or indirectly convertible into or exchangeable for
Common Stock or Preferred Stock.

                              (C) "Additional Shares of Common Stock" shall mean
all shares of Common Stock issued (or, pursuant to Subsection 2(d)(iii) of this
Certificate, deemed to be issued) by the Corporation after the date of issuance
of the Series A Preferred ("Original Issue Date"), other than:

                                     - 4 -
<PAGE>

                                (I) shares of Common Stock that on the Original
Issue Date of the first issued share of Series A Preferred Stock (the "First
Original Issue Date") are issued or issuable upon conversion of shares of Series
A Preferred then outstanding or then subject to issuance against receipt of
payment therefor in accordance with the Stock Purchase Agreement;

                                (II) shares of Common Stock issued or issuable
as a dividend or distribution on Series A Preferred;

                                (III) the Reserved Option Shares; or

                                (IV) shares of Common Stock issued or issuable
by reason of a dividend, stock split, split-up or other distribution on shares
of Common Stock excluded from the definition of Additional Shares of Common
Stock by the foregoing clauses (I), (II) and (III) or this clause (IV).

                  (ii) No Adiustment of Series A Conversion Price. No adjustment
in the number of shares of Common Stock into which the shares of Series A
Preferred are convertible shall be made, by adjustment in the applicable Series
A Conversion Price thereof, unless the consideration per share (determined
pursuant to Section 2(d)(v)) hereof for an Additional Share of Common Stock
issued or deemed to be issued by the Corporation is less than the applicable
Series A Conversion Price in effect on the date of, and immediately prior to,
the issue of such Additional Shares. Notwithstanding the other provisions of
this Section 2(d) to the contrary, no adjustment to the applicable Series A
Conversion Price shall be made as a result of (I) the issuance or deemed
issuance of any shares of Common Stock as a dividend with respect to which
holders of Series A Preferred Stock receive a ratable portion, (II) the issuance
of Common Stock as a result of conversion of the Series A Preferred Stock or the
issuance of any stock options or the issuance of any Common Stock as a result of
the exercise of options that are issued pursuant to option plans applicable to
employees, consultants, and/or directors approved by the Board of Directors,
(III) the issuance or deemed issuance of any shares of Common Stock or
securities convertible into Common Stock to financial institutions or lessors in
connection with commercial credit arrangements, equipment financings or similar
transactions or (IV) securities issued solely in consideration for the
acquisition (whether by merger or otherwise) by the Corporation of all or
substantially all of the capital stock or assets of any other entity or business
organization, or securities issued solely in consideration for the grant by or
to the Corporation of marketing rights, distribution rights, license rights or
similar rights granted by or to the Corporation in consideration of the exchange
of the proprietary technology, whether of the Corporation or any other entity,
provided that with respect to any issuance pursuant to the foregoing clauses
(I), (II) and (III) or (IV), the issuance of such securities is approved by all
of the members of the Board of Directors and as long as such securities are
issued for a price, or options are granted with an exercise price, of no less
than fair market value.

                  (iii) Issue of Options and Convertible Securities Deemed Issue
of Additional Shares of Common Stock. If the Corporation at any time or from
time to time after the First Original Issue Date shall issue any Options or
Convertible Securities or shall fix a record date for the determination of
holders of any class of securities entitled to receive any such Options or
Convertible Securities, then the maximum number of shares of Common Stock (as
set forth in the instrument relating thereto without regard to any provision
contained therein for a

                                     - 5 -
<PAGE>

subsequent adjustment of such number) issuable upon the exercise of such Options
or, in the case of Convertible Securities and Options therefor, issuable upon
the conversion or exchange of such Convertible Securities, shall be deemed to be
Additional Shares of Common Stock issued as of the time of such issue or, in
case such a record date shall have been fixed, as of the close of business on
such record date, provided that in any such case in which Additional Shares of
Common Stock are deemed to be issued:

                        (A) no further adjustment in the Series A Conversion
Price shall be made upon the subsequent issue of Convertible Securities or
shares of Common Stock upon the exercise of such Options or conversion or
exchange of such Convertible Securities and, upon the expiration of any such
Option or the termination of any such right to convert or exchange such
Convertible Securities, the Series A Conversion Price then in effect hereunder
shall forthwith be increased to the Series A Conversion Price that would have
been in effect at the time of such expiration or termination had such Option or
Convertible Securities, to the extent outstanding immediately prior to such
expiration or termination, never been issued, and the Common Stock issuable
thereunder shall no longer be deemed to be outstanding; and

                        (B) if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Corporation, or decrease in the number of shares of
Common Stock issuable, upon the exercise, conversion or exchange thereof, the
Series A Conversion Price computed upon the original issue thereof (or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities, provided that no readjustment pursuant to this clause
(B) shall have the effect of increasing the Series A Conversion Price to an
amount that exceeds the lower of (i) the Series A Conversion Price on the
original adjustment date, or (ii) the Series A Conversion Price that would have
resulted from any issuance of Additional Shares of Common Stock other than such
Stock Options or Convertible Securities between the original adjustment date and
such readjustment date.

                  (iv) Adjustment of Series A Conversion Price. If the
Corporation issues Additional Shares of Common Stock (including, without
limitation, Additional Shares of Common Stock deemed to be issued pursuant to
Section 2(d)(iii) hereof), without consideration or for a consideration per
share less than the Series A Conversion Price in effect on the date of and
immediately prior to such issue, then and in such event, the Series A Conversion
Price shall be reduced, concurrently with such issue, to a price (calculated to
the nearest tenth of a cent) determined by multiplying the Series A Conversion
Price by a fraction the numerator of which shall be the number of shares of
Common Stock outstanding immediately prior to such issue (including all shares
issuable upon the conversion of shares of Series A Preferred Stock and all
Reserved Option Shares) plus the number of shares of Common Stock that the
aggregate consideration received by the Corporation for the total number of
Additional Shares of Common Stock so issued would purchase at the Series A
Conversion Price in effect prior to such issue; and the denominator of which
shall be the number of shares of Common Stock outstanding immediately prior to
such issue (including all shares issuable upon the conversion of shares of
Series A Preferred Stock and all Reserved Option Shares) plus the number of such
Additional Shares of Common Stock so issued; provided that, for the purpose of
this Section 2(d)(iv), (i) all shares of Common Stock issuable upon conversion
of shares of Series A Preferred Stock outstanding immediately prior to such
issue shall be deemed to be outstanding, and (ii)

                                     - 6 -
<PAGE>

immediately after any Additional Shares of Common Stock are deemed issued
pursuant to Section 2(d)(iii) hereof, such Additional Shares of Common Stock
shall be deemed to be outstanding.

                  (v) Determination of Consideration. For purposes of this
Section 2(d), the "Net Consideration Per Share" shall mean the per share
consideration received by the Corporation for the issue of any Additional Shares
of Common Stock and shall be computed as follows:

                        (A) Cash and Property: such consideration shall:

                                (I) insofar as it consists of cash, be computed
at the aggregate of cash received by the Corporation, excluding amounts paid or
payable for accrued interest or accrued dividends;

                                (II) insofar as it consists of property other
than cash, be computed at the Fair Market Value thereof at the time of such
issue; and

                                (III) if the Corporation issues Additional
Shares of Common Stock together with other shares or securities or other assets
of the Corporation for consideration that covers both, be the proportion of such
consideration so received, computed in good faith by the Board of Directors as
provided in clauses (I) and (II) above.

                        (B) Options and Convertible Securities. The
consideration per share received by the Corporation for Additional Shares of
Common Stock deemed to have been issued pursuant to Section 2(d)(iii) hereof,
relating to Options and Convertible Securities, shall be determined by dividing

                                (x) the total amount, if any, received or
receivable by the Corporation as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such
consideration) payable to the Corporation upon the exercise of such Options or
the conversion or exchange of such Convertible Securities, or in the case of
Options for Convertible Securities, the exercise of such Options for Convertible
Securities and the conversion or exchange of such Convertible Securities, by

                                (y) the maximum number of shares of Common Stock
(as set forth in the instruments relating thereto, without regard to any
provision contained therein for a subsequent adjustment of such number) issuable
upon the exercise of such Options or the conversion or exchange of such
Convertible Securities.

                  (vi) Adjustment for Combinations or Consolidation of Common
Stock. If, at any time after the First Original Issue Date the number of shares
of Common Stock outstanding are decreased by a combination of the outstanding
shares of Common Stock, then following the record date fixed for such
combination (or the date of such combination, if no record date is fixed), the
applicable Series A Conversion Price shall be increased so that the number of
shares of Common Stock issuable on conversion of each share of Series A
Preferred shall be decreased in proportion to such decrease in outstanding
shares of Common Stock.

                                     - 7 -
<PAGE>

                  (vii) Adjustment for Stock Dividends, Splits, and the Like. If
the Corporation shall at any time after the applicable First Original Issue Date
fix a record date for the subdivision, split-up or stock dividend of shares of
Common Stock, then, following the record date fixed for the determination of
holders of shares of Common Stock entitled to receive such subdivision, split-up
or dividend (or the date of such subdivision, split-up or dividend, if no record
date is fixed), the Series A Conversion Price shall be appropriately decreased
so that the number of shares of Common Stock issuable on conversion of each
share of Series A Preferred shall be increased in proportion to such increase in
outstanding shares; provided, however, that the Series A Conversion Price shall
not be decreased at such time if the amount of such reduction would be an amount
less than $0.01, but any such amount shall be carried forward and reduction with
respect thereto made at the time of and together with any subsequent reduction
that, together with such amount and any other amount or amounts so carried
forward, shall aggregate $0.01 or more.

                  (viii) Adjustment for Merger or Reorganization, and the Like.
In case of any consolidation, recapitalization or merger of the Corporation with
or into another corporation or the sale of all or substantially all of the
assets of the Corporation to another corporation (other than a subdivision or
combination provided for elsewhere in this Section 2 and other than a
consolidation, merger or sale that is treated as a Liquidation Event pursuant to
Section 1 hereof), each share of Series A Preferred shall thereafter be
convertible into the kind and amount of shares of stock or other securities or
property to which a holder of the number of shares of Common Stock of the
Corporation deliverable upon conversion of such shares of Series A Preferred
would have been entitled upon such consolidation, merger or sale; and, in such
case, appropriate adjustment (as determined in good faith by the Board of
Directors) shall be made in the application of the provisions in this Section 2
set forth with respect to the rights and interest thereafter of the holders of
the shares of Series A Preferred, to the end that the provisions set forth in
this Section 2 (including provisions with respect to changes in and other
adjustments of the Series A Conversion Price) shall thereafter be applicable, as
nearly as reasonably may be, in relation to any shares of stock or other
property thereafter deliverable upon the conversion of the shares of Series A
Preferred.

            (e) No Fractional Shares. No fractional shares shall be issued upon
the conversion of any share or shares of Series A Preferred, and the number of
shares of Common Stock to be issued shall be rounded to the nearest whole share.

            (f) Reservation of Stock Issuable Upon Conversion. The Corporation
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of Series A Preferred, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of Series A Preferred.

            (g) No Impairment. The Corporation will not, by amendment of its
Certificate of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all the provisions of this
Section 2 and in the taking of all such action as may be necessary or

                                     - 8 -
<PAGE>

appropriate in order to protect the Conversion Rights of the holders of the
shares of Series A Preferred against impairment.

            (h) Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Series A Conversion Price pursuant to this
Section 2, the Corporation at its expense shall promptly compute such adjustment
or readjustment in accordance with the terms hereof and furnish to each holder
of shares of Series A Preferred a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any holder of Series A Preferred, furnish or cause to be furnished to
such holder a similar certificate setting forth (i) such adjustments and
readjustments, (ii) the Series A Conversion Price then in effect, and (iii) the
number of shares of Common Stock and the amount, if any, of other property that
then would be received upon the conversion of the shares of Series A Preferred.

            3. Voting Rights. (a) Each share of Series A Preferred stock shall
have the same voting rights as that number of shares of common stock into which
it may be convertible from time to time at the then Series A Conversion Price.

            (b) The following actions shall require the affirmative vote of all
Series A Designated Directors:

                  (i) any action by the Board to authorize, create, designate or
establish any class or series of capital stock ranking on a parity with, or
senior to Series A Preferred or reclassify any shares of common stock into
shares having any preference or priority as to dividends or assets superior to
or, on a parity with any such preference or priority of the Series A Preferred;
or to in any other manner alter or change the powers, preferences or rights, or
qualification, limitations or restrictions of the shares of Series A Preferred;

                  (ii) approval or authorization of any liquidation or winding
up or recapitalization or reorganization of the Seller; and

                  (iii) approval of any proposal to amend the certificate of
incorporation or bylaws of the Corporation in a manner that adversely affects
the rights of the holders of the Series A Preferred.

      FIFTH: The Secretary of State is designated as agent of the Corporation
upon whom process against it may be served. The post office address to whom the
Secretary of State shall mail a copy of any process against the Corporation
served upon him is:

                              Open-i Media, Inc.
                              73 Franklin Street
                              New York, New York 10013

      SIXTH: No director of the Corporation shall have personal liability to the
Corporation or to its shareholders for damages for any breach of duty in such
capacity, provided, however, that the provision shall not eliminate or limit:

            (a) the liability of any director of the Corporation if a judgment
or other final adjudication adverse to him establishes that his acts or
omissions were in bad faith or involved

                                     - 9 -
<PAGE>

intentional misconduct or a knowing violation of law or that he personally
gained in fact a financial profit or other advantage to which he was not legally
entitled or, with respect to any director of the Corporation, that his acts
violated Section 719 of the BCL, or

            (b) the liability of a director for any act or omission prior to the
final adoption of this article.

      SEVENTH: The holders of the Corporation's equity shares shall not be
entitled to preemptive rights in accordance with the provisions of section 622
of the BCL."

               AMENDED AND RESTATED REGISTRATION RIGHTS AGREEMENT

      THIS AGREEMENT made as of the 7th day of July, 2000, by and among Open-i

      WHEREAS, the Company desires to grant to the Investors registration rights
and certain other rights on the terms and conditions hereinafter set forth.

merger or consolidation or reorganization; provided, however, that shares of
Common Stock shall only be treated as Registrable Stock if and so long as they
are not eligible for sale without restriction under Rule 144(k) under the
Securities Act or have not been (i) sold to or through a broker or dealer or
underwriter in a public distribution or a public securities transaction, or (ii)
sold in a transaction under Rule 144 of the Securities Act so that all transfer
restrictions and restrictive legends with respect to such Common Stock are
removed upon the consummation of such sale.

      "Registration Statement" means a registration statement filed by the
Company with the Commission for a public offering and sale of securities of the
Company (other than a registration statement on Form S-8, Form S-4, or successor

issued in exchange for securities or assets of another corporation or which is
not available for registering the shares of Registrable Stock for sale to the
public).

      "Securities Act" means the Securities Act of 1933, or any successor

      2. Restrictive Legend. Each certificate representing Registrable Stock

imprinted with a legend substantially in the following form:

      "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933 OR ANY STATE SECURITIES LAWS AND MAY NOT BE TRANSFERRED OR OTHERWISE
DISPOSED OF UNLESS IT HAS BEEN REGISTERED UNDER SUCH ACT AND ALL SUCH APPLICABLE
LAWS OR IN THE OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AN EXEMPTION FROM
REGISTRATION IS AVAILABLE."

                                       2
<PAGE>

A certificate shall not bear such legend, or such legend shall be promptly
removed, if in the opinion of counsel satisfactory to the Company the securities
represented thereby may be publicly sold without registration under the
Securities Act and any applicable state securities laws or the Investor provides
the Company with a certificate that such Investor satisfies all the requirements
of Rule 144 (k).

      Each certificate for Registrable Stock shall bear the legend set forth in
this Section 2, except that such certificate shall not bear such legend if (i)
such transfer is in accordance with the provisions of Rule 144 (or any other
rule permitting public sale without registration under the Securities Act) or
pursuant to an effective registration statement, or (ii) an opinion of counsel
satisfactory to the Company to the effect that any proposed transfer of
Registerable Stock may be effected without registration under the Securities Act
and any applicable state securities laws and that the transferee and any
subsequent transferee (other than an affiliate of the Company) would be entitled
to transfer such securities in a public sale without registration under the
Securities Act.

      3. Registration Rights.

      3.1 Incidental Registration. Each time the Company shall determine to file
a Registration Statement in connection with the proposed offer and sale for
money of any of its securities by it or any of its security holders, the Company
will give written notice thereof to the Investors. Upon the written request of
one or more Investors given within twenty (20) days after the giving of any such
notice by the Company, the Company will use its reasonable best efforts to cause
all such shares of Registrable Stock, the Holders of which have so requested
registration thereof, to be included in such Registration Statement, all to the
extent requisite to permit the sale or other disposition by the prospective
seller or sellers of the Registrable Stock to be so registered. If the
Registration Statement is to cover an underwritten distribution, the Company
shall use its reasonable best efforts to cause the Registrable Stock requested
for inclusion pursuant to this Section 3.1 to be included in the underwriting on
the same terms and conditions as the securities otherwise being sold through the
underwriters. If, in the good faith judgment of the managing underwriter of such
public offering, the inclusion of all of the Registrable Stock requested for
inclusion pursuant to this Section 3.1 would interfere with the successful
marketing of a smaller number of shares to be offered, then the number of shares
of Registrable Stock and other securities to be included in the offering (except
for shares to be issued by the Company in an offering initiated by the Company)
shall be reduced to the required level by reducing (down to zero in the
Company's Initial Public Offering, or to not less than thirty (30%) percent
thereafter, if so required) the participation of the Holders of Registrable
Stock in such offering (such reduction to be made to the amounts of shares
requested for inclusion in such offering by such Holders on a pro rata basis
among the Holders of Registrable Stock requesting such registration, based upon
the number of shares of Registrable Stock owned by such Holders).
Notwithstanding the foregoing provisions, the Company may, in its sole
discretion, terminate, delay, abandon or withdraw any Registration Statement
referred to in this Section 3.1 without thereby incurring any liability to the
Holders of Registrable Stock.

                                       3
<PAGE>

      3.2 Requested Registration.

            (a) At any time beginning six (6) months after an Initial Public
Offering, an Investor (the "Initiating Holder") may by notice in writing to the
Company (which notice shall specify the number of shares of Registrable Stock
proposed to be sold and the intended method of disposition thereof) request the
Company to register under the Securities Act all or any portion of shares of
Registrable Stock held by such Initiating Holder or Investors for sale in the
manner specified in such notice. Notwithstanding anything to the contrary
contained herein, the Company shall not be required to seek to cause a
Registration Statement to become effective pursuant to this Section 3.2: (A)
within a period of 90 days after the effective date of any Registration
Statement (other than a Registration Statement on Forms S-4, S-8 or any
successors thereto), provided that the Company shall use its reasonable best
efforts to cause a registration requested hereunder to be declared effective
promptly following such period if such request is made during such period; or
(B) if the Company shall furnish to the Holders a certificate signed by the
President of the Company stating that in the good faith judgment of the Board it
would be materially detrimental to the Company or its stockholders for a
Registration Statement to be filed at such time, or that it would require
disclosure of material non-public information relating to the Company which, in
the reasonable opinion of the Board, should not be disclosed, then the Company's
obligation to use all reasonable efforts to register, qualify or comply under
this Section 3.2 shall be deferred for a period not to exceed ninety (90) days
from the date of receipt of written request from such Holders; provided,
however, that the Company may not utilize this deferral right more than once in
any twelve-month period.

            (b) Following receipt of any notice given under this Section 3 by
the Initiating Holders, the Company shall promptly notify in writing all
Investors that such registration is to be effected and, subject to the
provisions of the last sentence of Section 3.2(a), shall use its best reasonable
efforts to register under the Securities Act, for public sale in accordance with
the method of disposition specified in such notice from such requesting
Investors, the number of shares of Registrable Stock specified in such notice
(and in all notices received by the Company pursuant hereto). Investors, other
than the Initiating Holders, shall notify the Company of their desire to
participate in the Registration within twenty (20) days of the Company's notice
to them. The Company shall be obligated to register Registrable Stock pursuant
to Section 3.2(a) on two (2) occasions only, provided, however, that such
obligation shall be deemed satisfied only when a Registration Statement covering
all shares of Registrable Stock specified in notices received as aforesaid and
which have not been withdrawn by the Holder thereof, for sale in accordance with
the method of disposition specified by the Initiating Holders, shall have become
effective, except as set forth in the next sentence. A registration which does
not become effective after the Company has filed a Registration Statement with
respect thereto solely by reason of the refusal of the Initiating Holders to
proceed shall be deemed to have been effected by the Company at the request of
such Initiating Holders and the Company shall be deemed to have satisfied one of
its two obligations under this Section 3.2(a), unless the registration was
withdrawn at the request of the Holders of a majority of the Registrable Stock
to be sold in such offering upon learning of a material adverse change in the
condition, business or prospects of the Company (other than a change in market
demand for its securities or in the market price thereof) from that known to
such Holders at the time of their request (or of which the Company advised them
in writing

                                       4
<PAGE>

within 20 days thereafter) that makes the proposed offering unreasonable in the
good faith judgment of a majority in interest of such Holders.

            (c) If the Registration Statement is to cover an underwritten
distribution and in the good faith judgment of the managing underwriter of such
public offering the inclusion of all of the Registrable Stock requested for
inclusion pursuant to this Section 3 would interfere with the successful
marketing of a smaller number of shares to be offered, then the number of shares
of Registrable Stock to be included in the Offering shall be reduced to the
required level with the participation in such offering to be reduced to the
required level, as follows, unless otherwise determined by a majority in
interest of the Holders: first, by reducing (down to zero, if necessary) on a
pro rata basis the participation of any Persons who are not Holders and second,
by reducing on a pro-rata basis the participation of other Holders requesting
such registration; such pro rata basis to be calculated based upon the number of
shares of Registrable Stock owned by any such Holders or on the number of shares
of Stock owned by such Persons, as the case may be. The Company shall be
entitled to include in any Registration Statement referred to in this Section
3.2(a), for sale in accordance with the method of disposition specified by the
Initiating Holders, (i) shares of Stock for the Company's own account and (ii)
securities to be sold by stockholders of the Company other than the holders of
Registrable Stock to the extent all Registrable Stock set forth in such notice
are covered by such registration, except as and to the extent that, in the
opinion of the managing underwriter, if any, such inclusion would adversely
affect the marketing of the Registrable Stock to be sold.

      3.3 Registration Procedures. If and whenever the Company is required by
the provisions hereof to effect the registration of shares of Registrable Stock
under the Securities Act, the Company will, at its expense, as expeditiously as
practicable:

            (a) In accordance with the Securities Act and the rules and
regulations of the Commission, prepare and file with the Commission a
Registration Statement with respect to the Registrable Stock and use its
reasonable best efforts to cause such Registration Statement to become and
remain effective until the Registrable Stock covered by such Registration
Statement has been sold, but for no longer than twelve (12) months subsequent to
the effective date of such registration, and prepare and file with the
Commission such amendments to such Registration Statement and supplements to the
prospectus contained therein as may be necessary to keep such Registration
Statement effective and such Registration Statement and prospectus accurate and
complete until the Registrable Stock covered by such Registration Statement has
been sold, but for no longer than twelve (12) months subsequent to the effective
date of such registration;

            (b) If the offering is to be underwritten in whole or in part, enter
into a written underwriting agreement in form and substance reasonably
satisfactory to the managing underwriter, if any, of the public offering and the
Investors participating in such offering;

            (c) Furnish to the participating Investors and to the underwriters
such number of copies of the Registration Statement, preliminary prospectus,
final prospectus and such other documents as such underwriters and participating
Investors may reasonably request in order to facilitate the public offering of
such securities;

                                       5
<PAGE>

            (d) Use its reasonable best efforts to register or qualify the
Registrable Stock covered by such Registration Statement under such state
securities or blue sky laws of such jurisdictions (i) as shall be reasonably
appropriate for the distribution of the Registrable Stock covered by such
Registration Statement or (ii) as participating Investors and underwriters may
reasonably request within ten (10) days following the original filing of such
Registration Statement, except that the Company shall not for any purpose be
required to execute a general consent to service of process, to subject itself
to taxation, or to qualify to do business as a foreign corporation in any
jurisdiction where it is not so qualified;

            (e) Notify the participating Investors in writing promptly after it
shall receive notice thereof, of the date and time when such Registration
Statement and each post-effective amendment thereto has become effective or a
supplement to any prospectus forming a part of such Registration Statement has
been filed;

            (f) Notify the participating Investors promptly in writing of any
request by the Commission or any state securities commission or agency for the
amending or supplementing of such Registration Statement or prospectus or for
additional information;

            (g) Prepare and file with the Commission, promptly upon the request
of the participating Investors, any amendments or supplements to such
Registration Statement or prospectus which, in the opinion of counsel
representing the Company in such Registration, is required under the Securities
Act or the rules and regulations thereunder in connection with the distribution
of the Registrable Stock by the participating Investors, but for no longer than
twelve (12) months subsequent to the effective date of such registration;

            (h) Prepare and promptly file with the Commission, and promptly
notify the participating Investors of the filing of, such amendments or
supplements to such Registration Statement or prospectus as may be necessary to
correct any statements or omissions if, at the time when a prospectus relating
to such Registrable Stock is required to be delivered under the Securities Act,
any event has occurred as the result of which any such prospectus or any other
prospectus as then in effect would include an untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading; the sellers of
Registrable Stock agree upon receipt of such notice forthwith to cease making
offers and sales of Registrable Stock pursuant to such registration statement or
deliveries of the prospectus contained therein for any purpose until the Company
has prepared and furnished such amendment or supplement to the prospectus as may
be necessary so that, as thereafter delivered to purchasers of such Registrable
Stock, such prospectus shall not include an untrue statement of material fact or
omit to state a material fact required to be stated therein or necessary to make
the statements therein not misleading in light of the circumstances then
existing;

            (i) In case the participating Investors or any underwriter is
required to deliver a prospectus at a time when the prospectus then in
circulation is not in compliance with the Securities Act or the rules and
regulations of the Commission, prepare promptly upon request such amendments or
supplements to such Registration Statement and such prospectus as may be

                                       6
<PAGE>

necessary in order for such prospectus to comply with the requirements of the
Securities Act and such rules and regulations;

            (j) Advise the participating Investors, promptly after it shall
receive notice or obtain knowledge of the issuance of any stop order by the
Commission or any state securities commission or agency suspending the
effectiveness of such Registration Statement or the initiation or threatening of
any proceeding for that purpose and promptly use its reasonable best efforts to
prevent the issuance of any stop order or to obtain its withdrawal if such stop
order should be issued;

            (k) At the request of the participating Investors (i) furnish to the
underwriters, if such registration includes an underwritten public offering, at
the closing provided for in the underwriting agreement, copies of any opinion,
dated such date, of the counsel representing the Company for the purposes of
such registration, addressed to the underwriters, if any, covering such matters
with respect to the registration statement, the prospectus and each amendment or
supplement thereto, proceedings under state and Federal securities laws, other
matters relating to the Company, the securities being registered and the offer
and sale of such securities as are customarily the subject of opinions of
issuer's counsel provided to underwriters in underwritten public offerings and
(ii) use its reasonable best efforts to furnish to the participating Investors
letters dated each such effective date and such closing date, from the
independent certified public accountants of the Company, addressed to the
underwriters, if any, and to the participating Investors, stating that they are
independent certified public accountants within the meaning of the Securities
Act and dealing with such matters as the underwriters may request, or, if the
offering is not underwritten, that in the opinion of such accountants the
financial statements and other financial data of the Company included in the
Registration Statement or the prospectus or any amendment or supplement thereto
comply in all material respects with the applicable accounting requirements of
the Securities Act, and additionally covering such other financial matters,
including information as to the period ending not more than five (5) business
days prior to the date of such letter with respect to the Registration Statement
and prospectus, as the participating Investors may reasonably request;

            (l) Apply for listing and use its reasonable best efforts to list
the Registrable Stock being registered on any national securities exchange on
which a class of the Company's equity securities is listed or, if the Company
does not have a class of equity securities listed on a national securities
exchange, apply for qualification and use its reasonable best efforts to qualify
the Registrable Stock being registered for inclusion on the automated quotation
system of the National Association of Securities Dealers, Inc.;

            (m) Furnish, at least five (5) business days before filing a
Registration Statement, a prospectus relating thereto or any amendments or
supplements relating to such a Registration Statement or prospectus, to counsel
for the participating Investors (the "Investors' Counsel"), copies of all such
documents proposed to be filed (it being understood that such five (5) business
day period need not apply to successive drafts of the same document proposed to
be filed so long as such successive drafts are supplied to such counsel in
advance of the proposed filing by a period of time that is customary and
reasonable under the circumstances); and

                                       7
<PAGE>

            (n) Notify in writing the Investors' Counsel promptly (I) of the
receipt by the Company of any notification with respect to any comments by the
Commission with respect to such registration statement or prospectus or any
amendment or supplement thereto or any request by the Commission for the
amending or supplementing thereof or for additional information with respect
thereto, (ii) of the receipt by the Company of any notification with respect to
the issuance by the Commission of any stop order suspending the effectiveness of
such Registration Statement or prospectus or any amendment or supplement thereto
or the initiation or threatening of any proceeding for that purpose and (iii) of
the receipt by the Company of any notification with respect to the suspension of
the qualification of the Registrable Stock for sale in any jurisdiction or the
initiation or threatening of any proceeding for such purposes.

      3.4 Expenses.

            (a) With respect to each registration effected pursuant to this
Agreement, all fees, costs and expenses of and incidental to such registration
and the public offering in connection therewith shall be borne by the Company;
provided, however, (i) that the Investors and other holders of the Company's
stock participating in any such registration shall bear their pro rata share of
the underwriting discounts and selling commissions, and (ii) any such fee, cost
or expense which does not constitute a fee, cost or expense customary in such a
registration and which is attributable solely to one Investor or other holder of
the Company's stock participating in any such registration shall be borne by
that holder or Investor.

            (b) The fees, costs and expenses of registration to be borne as
provided in paragraph (a) above, shall include, without limitation, all
registration, filing and NASD fees, printing expenses, fees and disbursements of
counsel and accountants for the Company, fees and disbursements of counsel for
the underwriter or underwriters of such securities (if the Company and/or
selling security holders are otherwise required to bear such fees and
disbursements), all legal fees and disbursements and other expenses of complying
with state securities or blue sky laws of any jurisdictions in which the
securities to be offered are to be registered or qualified, and the premiums and
other costs of policies of insurance insuring the Company against liability
arising out of such public offering.

      3.5 Indemnification and Contribution.

            (a) The Company will indemnify and hold harmless each Investor whose
shares of Registrable Stock are included in a Registration Statement pursuant to
the provisions of this Agreement, from and against, and will reimburse each such
Investor with respect to, any and all claims, actions, demands, losses, damages,
liabilities, costs and expenses to which such Investor may become subject under
the Securities Act or otherwise, insofar as such claims, actions, demands,
losses, damages, liabilities, costs or expenses arise out of or are based upon
any untrue statement or allegedly untrue statement of any material fact
contained in such Registration Statement, any prospectus contained therein or
any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading or
arise out of any violation by the Company of any rule or regulation under the
Securities Act applicable to the Company and relating to action or inaction
required of the

                                       8
<PAGE>

Company in connection with such registration; provided, however, that the
Company will not be liable in any such case to the extent that any such claim,
action, demand, loss, damage, liability, cost or expense arises out of or is
based upon an untrue statement or alleged untrue statement or omission or
alleged omission so made in reliance upon and in conformity with information
furnished by or on behalf of any such Investor in writing specifically for use
in the preparation thereof.

            (b) Each Holder of shares of Registrable Stock which are included in
a Registration Statement pursuant to the provisions of this Agreement will
severally, but not jointly, indemnify and hold harmless the Company, each of its
directors, officers, agents and employees, each person who controls the Company
within the meaning of the Securities Act, from and against, and will reimburse
such parties with respect to, any and all losses, damages, liabilities, costs or
expenses to which such parties may become subject under the Securities Act or
otherwise, to the extent that any such loss, damage, liability, cost or expense
arises out of or is based upon any untrue or alleged untrue statement of any
material fact contained therein or any amendment or supplement thereto, or
arises out of or is based upon any omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading, in each case to the extent, but only to the
extent that such untrue statement or alleged untrue statement or omission or
alleged omission was so made in reliance upon and in conformity with written
information furnished by or on behalf of such Holder specifically for use in the
preparation thereof. Notwithstanding the foregoing, in no event shall any such
Investor be required to indemnify and hold harmless the Company, each of its
directors, officers, agents, employees, or each person who controls the Company
within the meaning of the Securities Act for any amount exceeding in the
aggregate the net proceeds received by such Investor from the sale of
Registrable Stock covered by the Registration Statement.

            (c) Promptly after receipt by a party to be indemnified pursuant to
the provisions of paragraph (a) or (b) of this Section 3.5 (an "indemnified
party") of actual knowledge or notice of the commencement of any action
involving the subject matter of the foregoing indemnity provisions, such
indemnified party will, if a claim thereof is to be made against the
indemnifying party pursuant to the provisions of paragraph (a) or (b), notify
the indemnifying party of the commencement thereof; but the omission so to
notify the indemnifying party will not relieve it from any liability which it
may have to an indemnified party otherwise than under this Section 3.5 and shall
not relieve the indemnifying party from liability under this Section 3.5 unless
such indemnifying party is prejudiced by such omission. In case such action is
brought against any indemnified party and it notifies the indemnifying party of
the commencement thereof, the indemnifying party shall have the right to
participate in, and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party will not be liable to such
indemnified party pursuant to the provisions of such paragraph (a) and (b) for
any legal or other expense subsequently incurred by such indemnified party in
connection with the defense thereof other than reasonable costs of
investigation. Notwithstanding the foregoing, an indemnified party shall have
the right to retain its own counsel, with the reasonable fees and expenses to be
paid by the indemnifying party, if

                                       9
<PAGE>

representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests, as reasonably determined by either party, between such indemnified
party and any other party represented by such counsel in such proceeding. No
indemnifying party shall be liable to an indemnified party for any settlement of
any action or claim without the consent of the indemnifying party; no
indemnifying party may unreasonably withhold its consent to any such settlement.
No indemnifying party will consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving by
the claimant or plaintiff to such indemnified party of a release from all
liability in respect to such claim or litigation.

      3.6 Reporting Requirements Under Securities Exchange Act of 1934. When it
is first legally required to do so, the Company shall register its Common Stock
under Section 12 of the Exchange Act and shall keep effective such registration
and shall timely file such information, documents and reports as the Commission
may require or prescribe under Section 13 of the Exchange Act. From and after
the effective date of the first Registration Statement filed by the Company, the
Company shall use its reasonable best efforts to (whether or not it shall then
be required to do so) timely file such information, documents and reports as the
Commission may require or prescribe under Section 13 or 15(d) (whichever is
applicable) of the Exchange Act. Immediately upon becoming subject to the
reporting requirements of either Section 13 or 15(d) of the Exchange Act, the
Company shall forthwith upon request furnish any Investor (i) a written
statement by the Company that it has complied with such reporting requirements,
(ii) a copy of the most recent annual or quarterly report of the Company, and
(iii) such other reports and documents filed by the Company with the Commission
as such Investor may reasonably request in availing itself of an exemption for
the sale of Registrable Stock without registration under the Securities Act. The
Company acknowledges and agrees that the purposes of the requirements contained
in this Section 3.6 are (a) to enable any such Investor to comply with the
current public information requirement contained in Paragraph (c) of Rule 144
under the Securities Act should such Investor ever wish to dispose of any of the
securities of the Company acquired by it without registration under the
Securities Act in reliance upon Rule 144 (or any other similar or successor
exemptive provision), and (b) to qualify the Company for the use of Registration
Statements on Form S-3. In addition, the Company shall take such other measures
and file such other information, documents and reports, as shall hereafter be
required by the Commission as a condition to the availability of Rule 144 under
the Securities Act (or any similar or successor exemptive provision hereafter in
effect) and the use of Form S-3. The Company also covenants to use its
reasonable best efforts, to the extent that it is reasonably within its power to
do so, to qualify for the use of Form S-3. From and after the effective date of
the first Registration Statement filed by the Company, the Company agrees to use
its reasonable best efforts to facilitate and expedite transfers of Registrable
Stock pursuant to Rule 144 under the Securities Act (or any similar or successor
exemptive provision hereafter in effect), which efforts shall include timely
notice to its transfer agent to expedite such transfers of Registrable Stock.

      3.7 Stockholder Information. The Company may require each of the Investors
to furnish the Company in a timely manner such information with respect to such
Investor and the distribution of such Registrable Stock as the Company may from
time to time reasonably request in writing and as shall be required by law or by
the Commission in connection therewith.

      3.8 Lock-Up Agreements.

            (a) Restrictions on Public Sale by the Company. The Company agrees
not to effect any public sale or other distribution of its equity securities, or
any securities convertible into or exchangeable or exercisable for such equity
securities, during the period (not to exceed one hundred eighty (180) days) as
requested by the managing underwriter, following the effective date of the
Initial Public Offering, except in connection with any such offering and except
for equity securities issued pursuant to employee stock option or employee stock
purchase plans or in conjunction with any merger or consolidation with, or
acquisition of the stock or assets of, any other entity.

            (b) Restrictions on Public Sale by the Investors. Each Investor
agrees that in conjunction with the Initial Public Offering it will not, to the
extent requested by the Company and the managing underwriter of such offering,
sell or otherwise dispose of any equity securities of the Company, including any
sale pursuant to Rule 144, during a period specified by the Company and such
underwriter (not to exceed one hundred eighty (180) days after the effective
date of the Initial Public Offering), provided that all other shareholders of
the Company are subject to similar restrictions except (i) in conjunction with
such offering or (ii) to any Affiliates of such Holder who agree to be bound by
the restrictions on dispositions set forth herein; and provided that each
officer and director of the Company shall enter into similar agreements.

            (c) In the event any of the Registrable Stock of an Investor is
included in an Initial Public Offering, the Company shall cause the Registration
Statement covering such stock to remain effective until such stock has been
sold, but for no longer than fifteen (15) months subsequent to the effective
date of such registration.

            WHEREAS, the Shareholders are the record owners of all of the shares
of the capital stock of the Company; and

            WHEREAS, on May 4, 2000, the Company and all of its then
shareholders entered into a Shareholders Agreement (the "Original Shareholders
Agreement"); and

            WHEREAS, the parties believe that it is in the best interests of the
Company and the Shareholders to amend and restate the Original Shareholders
Agreement in its entirety as set forth herein.

            NOW, THEREFORE, in consideration of the premises, the mutual
covenants herein contained, and other good and valuable consideration, it is
hereby agreed as follows:

      1. DEFINITIONS. For the purposes of this Agreement the following terms
shall have the meanings set forth in this Article 1:

                  1.1 "Lock Up Period" shall have the meaning set forth in

                  1.4 "Selling Shareholder" shall mean the Shareholder or the

                  1.5 "Shares" shall mean all shares of the capital stock of the
Company now or hereafter owned by the Shareholders and their Permitted
Transferees regardless of when or how acquired.

                  1.6 "Transfer" shall mean any disposition (including, without

other intervivos or testamentary dispositions) whether voluntary or involuntary,
or pursuant to court order or by operation of law.

            2. ENTIRE AGREEMENT. This Agreement represents the entire
understanding of the parties regarding the disposition of the Shares, now or
hereafter owned by them, during the Shareholders' lives or upon their deaths,
and supersedes any and all other oral or written agreements among them, which

            3. LIMITATION ON TRANSFERS OF SHARES.

                  3.1 Limitation. No Shareholder may Transfer all or any of such
Shareholder's Shares except as provided in this Agreement, including the
provisions of Article 4.

                  3.2 Reasonableness of Restraints. The Shareholders recognize
and acknowledge that the restraints imposed in this Agreement on the disposition
of their Shares are fair and reasonable in consideration of their absolute
necessity for the proper conduct of the business of the Company, and in

Shares, at a fair price, upon their death.

            4. PERMITTED TRANSFERS OF SHARES.

                  4.1 Transfers with Prior Consent of all other Shareholders.
Except as otherwise provided in Section 4.2 or 4.4, a Shareholder may only
Transfer the Shares owned by such Shareholder if such Shareholder has obtained
the prior written consent of all of the other Shareholders of the Company. Any
Shares so Transferred pursuant to this Section 4.1 shall continue to be subject
to and shall be transferable only in accordance with the terms of this Agreement
and the transferee of such Shares must agree in writing to be bound by the terms
and conditions of this Agreement prior to such Transfer being effective.

                  4.2 Lifetime Transfers Subject to Right of First Refusal.

                        (a) Except as otherwise provided in Section 4.1 or 4.4
hereof; no Shareholder shall Transfer any of the Shares owned by such
Shareholder unless the Selling Shareholder shall have first made the offer to
sell set forth in Section 4.2(b) (the "Offer Notice") and such offer shall not
have been accepted; and the Shares shall be transferable only in compliance with
the terms hereof. Any attempted Transfer of Shares in violation of this

                                      -2-
<PAGE>

Agreement shall be deemed an irrevocable offer by such Shareholder to sell such
Shares to the Company pursuant to Section 4.2 hereof.

                        (b) The Offer Notice shall be given in writing to the
Company and the Remaining Shareholders concurrently and shall state that the
Selling Shareholder offers to sell those Shares of the Selling Shareholder which
the Selling Shareholder proposes to Transfer in a bona fide transaction to the
Company or the Remaining Shareholders at the price and on the terms therein set
forth, and to such Offer Notice shall be attached a statement of intention to
Transfer such Shares, in a bona fide transaction, which shall set forth the name
and address of the prospective purchaser, transferee, lienor, or recipient of
any other disposition, the number of Shares involved in the proposed Transfer
and the terms of such proposed Transfer.

                        (c) Within fifteen (15) days after the receipt of such
Offer Notice, the Company may, by written notice to the Selling Shareholder,
elect to purchase all, but not less than all, of the Shares owned by such
Shareholder so offered at the price and on the terms set forth in the Offer
Notice. If the Offer Notice is not accepted by the Company, the Remaining
Shareholders may, by written notice to the Selling Shareholder given within
thirty (30) days after the receipt of the Offer Notice (the "Expiration Date"),
elect to purchase all, but not less than all, of the offered Shares at the price
and on the terms set forth in the Offer Notice in such proportions as may be
mutually agreed among the Remaining Shareholders or, in the absence of such
agreement, pro rata based on the percentage that each Remaining Shareholder's
Shares constitute of the total outstanding Shares of all shareholders who
exercise the right. A Remaining Shareholder may, if it so elects, purchase
additional portions of the offered Shares if any other Remaining Shareholder
does not exercise its right to purchase up to the full amount of its pro rata
amount of the offered Shares. Such additional portions of the offered Shares, if
any, shall be allocated to such Remaining Shareholders pro rata if more than one
Remaining Shareholder so elects, or less than pro rata with respect to any such
Remaining Shareholder requesting a lower amount of the additional portion of the
offered Shares. The notice of acceptance of the Offer Notice shall specify a
date for the closing of the purchase, which date shall be not more than thirty
(30) days after the date of the giving of such notice by the Company or the
Remaining Shareholders. The closing shall take place at the principal business
office of the Company.

                        (d) If the Offer Notice is not accepted by the Company
or the Remaining Shareholders for one hundred percent (100%) of the offered
Shares, the Selling Shareholder may make a bona fide Transfer to the prospective
purchaser, transferee, lienor, or recipient of any other disposition named in
the statement of intention attached to the Offer Notice, but only in strict
accordance with the terms therein stated; provided, however, that such
purchaser, transferee, lienor or recipient must agree in writing to be bound by
the terms of this Agreement prior to such Transfer becoming effective; and
provided further that each Shareholder shall have the right to join in such sale
set forth in Section 4.2(e) below. If the Selling Shareholder shall fail to make
such Transfer within thirty (30) days following the expiration of the time
provided in Section 4.2(c) for the election by the Potential Participants to
join in such sale as

                                      -3-
<PAGE>

set forth in Section 4.2(e) below, such Shareholder's Shares shall again become
subject to all the restrictions of this Agreement.

                        (e) In the event the right of first refusal of the
Company set forth in this Section 4.2 is not exercised by the Company or the
Remaining Shareholders, and such Shareholder is James Chong or his Permitted
Transferees ("Chong"), Chong shall not sell any of his Shares unless he has
first given each of the other Shareholders (the "Potential Participants") the
opportunity to join in such sale on a pro-rata basis on the same terms as Chong.
Each Potential Participant shall have the right to sell a number of Shares owned
by him equal to the product of (i) the total number of Shares proposed to be
sold to the purchaser and (ii) a fraction, the numerator of which shall be the
number of Shares owned by such Potential Participant and the denominator of
which shall the number of Shares owned by all Shareholders who have elected to
participate in such sale (including Chong). The right specified in this Section
4.2 may be exercised by a Potential Participant by delivery, not later than 10
days after the Expiration Date, of a written notice stating the number of Shares
that such Potential Participant wishes to include in such sale. Chong, together
with any electing Potential Participants, shall have the right for 90 days after
the date of the Sale Notice to sell or otherwise transfer Shares held by them to
the purchaser specified in the Offer Notice on the terms set forth therein. The
provisions of this Section 4.2 shall apply anew to any proposed sale after such
90 day period, or to any modification to the type or amount of consideration to
be paid or received in connection with such sale. The provisions of this Section
4.2 shall not apply to any Transfers otherwise permitted under the other
subsections of Section 4.

                        (f) If Chong or his Permitted Transferees give the
Shareholders notice that they desire to sell the Company (whether by merger,
consolidation, sale of all or substantially all of its assets, sale of all of
the outstanding common stock of the Company, share exchange or otherwise), all
Shareholders will consent to and raise no objections against such sale, and if
such sale is structured as a sale of stock, all Shareholders agree to sell all
of their Shares and rights to acquire Shares (if any) on the terms and
conditions approved by the Company's Board of Directors or the holders of a
majority of the common stock of the Company then outstanding. The Shareholders
will take all necessary and desirable actions reasonably requested by the
Company in connection with the consummation of such sale, at the sole cost of
the Company. The obligations of the Shareholders to participate in such sale are
subject to the satisfaction of the conditions that ( i) all Shareholders will
have the right to participate in such sale, (ii) the Shareholders will each
receive the same value of consideration per share, and (iii) the value of the
consideration per share in such sale will be not less than the following for the
year in which the sale for such closing takes place: $1.56 prior to or on June
30, 2001; $1.87 after June 30, 2001 but prior to or on June 30, 2002; $2.25
after June 30, 2002 but prior to or on June 30, 2003; $2.70 after June 30, 2003
but prior to or on June 30, 2004; and $3.24 thereafter.

and deliver to the Selling Shareholder a non-negotiable promissory note which
provides (i) for not less than twelve (12) but no more than fifteen (15) (as
determined by the Company, in its sole discretion) equal principal installments,
with the first installment being payable three (3) months after the closing, and
the remaining installments payable quarterly thereafter; (ii) for interest on
the unpaid balance of the note accruing at the minimum rate necessary under the
Code, to avoid the imputation of interest; and (iii) that the Company may prepay
all or any part thereof at any time with interest to the date of prepayment, but
any partial prepayment shall be applied against the unpaid principal balance
then outstanding in the inverse order of maturity.

                  6.3 Offset. The Company shall have the right to offset against

Shareholder, the amount of all sums due from the Selling Shareholder to the
Company, and to the extent so credited against the purchase price, such loan or
other indebtedness shall be deemed to be and shall be cancelled and discharged.
Such credit against the purchase price shall be made regardless of the due date
of any such loan or other indebtedness.

required to be given, it shall be in writing and shall be deemed given when
mailed, postage prepaid, by registered or certified mail, return receipt
requested, addressed to the Shareholders at their addresses as set forth on
Schedule A attached hereto, or to such other address as may appear on the record
books of the Company, and addressed to the Company at its principal business

            7th day of July, 2000 made among the Company and the shareholders
            named therein.

and not exclusive and shall be in addition to any other remedies which any party
or the Company may have under this Agreement or otherwise.

to amend or supplement Schedule A to this Agreement from time to time to reflect
additions and deletions to the Shareholders who are parties hereto.

                  10.2 Impairment Of Rights. No amendment, supplement or
termination of this Agreement (including a termination of this Agreement
pursuant to Sections 10.6(a) or 10.6(b) of this Agreement) shall affect or
impair any rights or obligations which have theretofore matured hereunder.

                  10.3 Further Assurances. All parties will take such further
action and execute such other documents as are reasonably necessary to
effectuate the purposes, terms and conditions of this Agreement.

                  10.4 Partial Invalidity. The invalidity of any portion of this
Agreement shall not affect the validity of the remainder of this Agreement.

                  10.5 Binding On Successors. This Agreement shall be binding
upon and shall inure to the benefit of all of the parties hereto, and to their
respective heirs, executors, administrators, successors and assigns, transferees
and Permitted Transferees and shall be binding upon any person to whom any

New York, NY 10022

Gentlemen:

      We have acted as counsel to Open-i Media, Inc., a New York corporation
(the "Company"), in connection with the issuance and sale by the Company to you,
as Purchaser, of 1,143,000, shares of its Series A Preferred Stock, $0.001 par
value per share ("Series A Preferred Stock") pursuant to the Stock Purchase
Agreement of even date herewith by and between the Company and you (the "Stock
Purchase Agreement").

      In so acting, we have examined originals or copies, certified or otherwise
identified to our satisfaction, of the Stock Purchase Agreement, the
Shareholders Agreement of even date herewith among the Company, you and the
other parties thereto (the "Shareholders Agreement") and the Registration Rights
Agreement of even date herewith among the Company, you and the other parties
thereto (the "Registration Rights Agreement" and, together with the Stock
Purchase Agreement and the Shareholders Agreement, the "Transaction Documents"),
and we have examined originals or copies, certified or otherwise identified to
our satisfaction, of such corporate records and other documents and instruments
of the Company and certificates or comparable documents of public officials and
of officers and representatives of the Company and have made such inquiries of
such officers and representatives, and considered such questions of law, as we
have deemed relevant and necessary as the basis for the opinions hereinafter set
forth. Capitalized terms used but not otherwise defined herein shall have the
meanings set forth in the Stock Purchase Agreement.

      In such examinations, we have assumed the genuineness of all signatures
(except the signatures of the officers of the Company on the Transaction
Documents) and the authenticity of all documents submitted to us as originals
and the conformity to authentic original documents of documents submitted to us
as certified, photostatic or telecopied copies. As to all questions of fact
material to this opinion that have not been independently established, we have
relied upon representations made to us by officers or representatives of the
Company, either orally or in certificates or other comparable documents, and
have relied upon the relevant facts stated therein. For purposes of this
opinion, the phrase "to our knowledge" or

<PAGE>
July 7, 2000
Page 2

with respect to matters "known to us" or "to our knowledge" is based on our
review of the stock records and minute books of the Company, and is based solely
on information actually known to those attorneys currently practicing with this
firm and engaged in the representation of the Company in connection with the
transactions contemplated by the Stock Purchase Agreement.

      This opinion is based exclusively upon and is limited to the laws of the
State of New York and the federal law of the United States. Statements in this
opinion as to the legality, validity, binding effect and enforceability of any
of the Transaction Documents and any other agreements referred to herein and
therein are limited by and subject to equitable principles and to applicable
bankruptcy, reorganization, insolvency, moratorium and other similar laws
affecting the enforceability of creditors' rights generally and to applicable
restrictions on the enforceability of indemnification and contribution; and are
further limited as we express no opinion as to the validity or enforceability of
the indemnification and contribution provisions of the Registration Rights
Agreement.

      Based upon the foregoing, and subject to the qualifications stated herein,
we are of the opinion that:

      1. The Company is a corporation validly existing and in good standing
under the laws of the State of New York. The Company has the corporate power and
authority to own and hold its properties and to carry on its business in all
material respects as, to our knowledge, it is currently conducted. The Company
has the corporate power to (a) execute, deliver and perform each of the
Transaction Documents, (b) issue, sell and deliver the Purchased Shares and (c)
issue and deliver the shares of common stock ("Common Stock") into which the
Purchased Shares are convertible upon conversion of the Purchased Shares (the
"Conversion Shares").

      2. Each of the Transaction Documents has been duly authorized, executed
and delivered by the Company and constitutes the legal, valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms.

      3. The execution and delivery by the Company of each of the Transaction
Documents, the performance by the Company of its obligations thereunder, the
issuance, sale and delivery of the Purchased Shares and the issuance and
delivery of the Conversion Shares upon conversion of the Purchased Shares will
not violate any provision of law, the Restated Certificate of Incorporation, as
amended, or By-laws, as amended, of the Company, in each case as in effect on
the date hereof, any order known to us of any court or other agency of
government or any indenture, agreement or other instrument known to us to which
the Company is bound, or conflict with, result in a breach of, or constitute
(with due notice or lapse of time or both) a default under any such indenture,
agreement or other instrument, except for such violations as would not have a
Material Adverse Effect on the Condition of the

<PAGE>

Page 3

Company, or, except as provided in the Stock Purchase Agreement, result in the
creation or imposition of any lien, charge, restriction, claim or encumbrance of
any nature whatsoever upon any of the properties or assets of the Company. In
rendering the opinion expressed in this paragraph, we have assumed full
disclosure to you of all material facts concerning the Company, its operations,
its financial condition and, with respect to performance by the Company of its
obligations under the Registration Rights Agreement, we have assumed compliance
by the Company at such time with the Securities Act of 1933, as amended (the
"Securities Act"), and the applicable rules and regulations thereunder and with
applicable state securities laws and the applicable regulations thereunder.

      4. The authorized capital stock of the Company consists of 40,000,000
shares of common stock and 10,000,000 shares of preferred stock, $0.001 par
value per share. The Company shall have outstanding immediately after the
Closing 6,000,000 shares of Common Stock and 3,143,000 shares of Series A
Preferred Stock, all of which have been validly issued and are fully paid and
nonassessable by the Company. The designations, powers, preferences, rights,
limitations and restrictions in respect of each class or series of authorized
capital stock of the Company are as set forth in its Restated Certificate of
Incorporation, and all such designations, powers, preferences, rights,
qualifications, limitations and restrictions are valid, binding and enforceable
and in accordance with all applicable laws.

      5. The Purchased Shares and the Conversion Shares have been duly
authorized. The issuance, sale and delivery of the Purchased Shares and the
issuance and delivery of the Conversion Shares upon conversion of the Purchased
Shares have been duly authorized by all required corporate action; the Purchased
Shares, when issued and paid for in accordance with the terms of the Stock
Purchase Agreement, will be validly issued, fully paid and non-assessable by the
Company. The Conversion Shares issuable upon conversion of the Purchased Shares
have been reserved for issuance by the Company and when issued upon conversion
of the Purchased Shares, the Conversion Shares will be validly issued, fully
paid and non-assessable by the Company.

      6. No registration or filing with, and no consent or approval of; or other
action by, any Federal, state or other governmental agency or instrumentality is
or will be necessary for the valid execution, delivery and performance by the
Company of the Transaction Documents, the issuance, sale and delivery of the
Purchased Shares, or the issuance and delivery of the Conversion Shares upon
conversion of the Purchased Shares, other than (i) the filing of the Restated
Certificate with the Department of State of the State of New York, and (ii) a
filing with the United States Securities and Exchange Commission of a Notice of
Sale of Securities on Form D, which the Company has represented to us that it
will file in a timely fashion. In rendering the opinion expressed in this
paragraph, we have assumed the accuracy of the representations and warranties of
the Purchasers set forth in Article 4 of the Stock Purchase Agreement. In
rendering the opinion expressed in this paragraph with respect to the
performance by the Company of its obligations under the Registration Rights
Agreement, we

<PAGE>

have also assumed compliance by the Company at such time with the Securities Act
and the applicable rules and regulations thereunder and with applicable state
securities laws and the applicable regulations thereunder.

      We advise you that Michael E. Helmer, Esq., a partner of our firm, is the
Assistant Secretary of the Company.

      This letter is furnished by us, as counsel to the Company, in connection
with the consummation of the transactions contemplated by the Stock Purchase
Agreement and is solely for your benefit. This opinion may not be relied upon by
you for any other purposes, or relied upon by any other person, firm,
corporation or other entity for any purpose, without our prior written consent.

                                                    Very truly yours,
