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

                                    ARTICLE I

Lender a promissory note in favor of the Lender in the principal amount of

         2.1. Organization and Qualification.

                  (a) The Company is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware and has
the requisite corporate power to carry on its business as it is now being
conducted. The Company is duly qualified as a foreign corporation to do
business, and is in good standing, in each jurisdiction where the character of
the properties owned or leased by it or the nature of its activities makes such
qualification necessary.

                  (b) The Company does not own, directly or indirectly,
beneficially or of record, any capital stock (or securities convertible into, or
options, warrants or rights to purchase, capital stock or such securities) or
other ownership, economic or voting interest in any corporation, partnership,
limited liability company, trust, joint venture or other entity of any kind.

                  (c) The Company's Certificate of Incorporation and Bylaws
have not been amended since July 27, 2000.

         2.2. Authorization.

                  (a) The Company has all requisite corporate power and
authority to execute and deliver (i) this Agreement, (ii) the Note, (iii) the
Warrant, (iv) the Security Agreement, dated as of the date hereof, among the
Company and the Lender, and (v) the Intercreditor Agreement, dated the date
hereof, among the Company, the Lender and the other parties named therein
(collectively, the "Transaction Documents"), and to consummate the transactions
contemplated hereby and thereby. The execution and delivery of this Agreement
and the other Transaction Documents by the Company and the consummation by the
Company of the transactions contemplated hereby and thereby (including the
issuance of the shares of Common Stock, par value $.01 per share ("Common
Stock"), of the Company issuable pursuant to the Notes and Warrants
(collectively, the "Conversion Shares")), have been duly and validly authorized
by the Board of Directors of the Company, and no other corporate proceedings on
the part of the Company are necessary to authorize this Agreement or the other
Transaction Documents or to consummate the transactions contemplated by this
Agreement or the other Transaction Documents, including any stockholder
approval. Each of this Agreement and the other Transaction Documents has been
duly and validly executed and delivered by the Company, and, assuming such
Transaction Document constitutes a valid and binding obligation of the Lender,
such Transaction Document constitutes a valid and binding agreement of the
Company, enforceable against the Company in accordance with its terms, subject
to applicable bankruptcy and other laws affecting creditors' rights generally
and to general principles of equity.

                  (b) The Conversion Shares are duly authorized and reserved for
issuance and, upon issuance in accordance with the Transaction Documents, will
be validly issued, fully paid and non-assessable, and free from all Liens.
Except as provided in Article IV hereof or as set forth in Schedule 2.2, neither
the issuance, sale or delivery of the Note and Warrant nor the issuance or
delivery of Conversion Shares is subject to any preemptive right of stockholders
of the Company or to any right of first refusal or similar right in favor of any
person. As used

limited liability company, joint venture or other organization or entity of any
kind.

         2.3. Consents and Approvals. Except as set forth in Schedule 2.3,
neither the execution and delivery of this Agreement and the other Transaction
Documents by the Company nor the consummation of the transactions contemplated
hereby and thereby (including the issuance of the Note and Warrant and the
issuance of the Conversion Shares) will conflict with, or result in any
violation of or default (with or without notice or lapse of time, or both)
under, or give rise to a right of termination, cancellation or acceleration of
any obligation or to loss of a material benefit under, or result in the creation
of, or give rise to, any claim, option, lien, charge, pledge, right of first
refusal, "tag" or "drag" along right, security interest or encumbrance of any
kind or nature whatsoever (collectively "Liens") upon any of the properties or
assets or the Company under:

                  (a) the Certificate of Incorporation or Bylaws of the Company,

                  (b) any loan or credit agreement, note, bond, mortgage,
indenture, lease, contract, agreement, instrument, permit, governmental
authorization, concession, franchise or license applicable to the Company or its
properties or assets, or

                  (c) any judgment, order, decree, statute, law, ordinance, rule
or regulation applicable to the Company or its properties or assets.

         No consent, approval, order or authorization of, or registration,
declaration or filing with, any Authority (as defined in Section 2.8) is
required by the Company in connection with the execution and delivery of this
Agreement or the other Transaction Documents by the Company or the consummation
by the Company of the transactions contemplated hereby or thereby (including the
issuance of the Note and Warrant and the Conversion Shares).

         2.4. Capitalization.

                  (a) As of the date hereof, the authorized capital stock of the
Company consists of 200,000,000 shares of Common Stock and 20,000,000 shares of
preferred stock, par value $.01 per share. As of the date hereof, 30,000,000
shares of Common Stock are issued and outstanding, and no shares of Common Stock

outstanding shares of Common Stock have been duly authorized and validly issued,

<PAGE>   7



respect of each outstanding stock option, each outstanding warrant and the
outstanding convertible notes.

                  (b) Except as set forth in paragraph (a) above (or as
expressly contemplated by this Agreement), there are no outstanding securities,
options, warrants, calls, rights, commitments, agreements, arrangements or
undertakings of any kind to which the Company is a party or by which it is bound
obligating the Company to issue, deliver or sell, or cause to be issued,
delivered or sold, directly or indirectly, additional shares of capital stock or
other voting securities (or securities convertible into or exchangeable for such
securities) of the Company, or obligating the Company to issue, grant, extend or
enter into any such security, option, warrant, call, right, commitment,
agreement, arrangement or undertaking. There are no bonds, debentures, notes or
other indebtedness of the Company having the right to vote (or convertible into,
or exchangeable for, securities having the right to vote) on any matters on
which stockholders of the Company may vote. Except as set forth in Schedule
2.4(b) (or as expressly contemplated by this Agreement), there are not any
outstanding contractual obligations of the Company to repurchase, redeem or
otherwise acquire, or providing preemptive or registration rights with respect
to, any shares of capital stock of the Company. Except as set forth on Schedule
2.4(b), there are no anti-dilution or price adjustment provisions contained in
any security issued by the Company (or in any agreement providing rights to
security holders) that will be triggered by the issuance of the Note or Warrant
or any Conversion Shares. Except as set forth on Schedule 2.4(b), the Company
does not have outstanding any loans to any person in respect of the purchase of
securities issued by the Company.

                  (c) Except for on Schedule 2.4(c), there are no voting trusts
or agreements, stockholders agreements, pledge agreements, buy-sell agreements,
rights of first refusal, preemptive rights or proxies relating to any securities
of the Company to which the Company is a party, or, to the Company's knowledge,
any of such instruments to which it is not a party. All of the outstanding
securities of the Company were issued in compliance with all applicable Federal
and state securities laws, including the Securities Act of 1933, as amended (the
"Securities Act").

         2.5. Financial Statements. The Company has made available to the Lender
copies of the audited financial statements of the Company for the annual period
ended, and as of, December 31, 1999, together with the audit reports thereon of
Arthur Andersen LLP (the "Audited Financial Statements"). The Audited Financial
Statements are in accordance with the books and records of the Company, and
fairly present in accordance with generally accepted accounting principles
("GAAP") consistently applied the assets, liabilities and financial position of
the Company, as at the respective dates thereof, and the results of its
operations for the periods covered thereby. The Company also has made available
to the Lender a copy of the unaudited financial statements of the Company (the
"Interim Financial Statements" and, together with the Audited Financial
Statements, the "Financial Statements") for the six (6) month period ended, and
as of, June 30, 2000. The Interim Financial Statements are consistent with the
books and records of the Company and fairly present in accordance with GAAP
consistently applied (except that the Interim Financial Statements do not
include all required note disclosures) the assets, liabilities and financial
position of the Company as at the respective dates thereof, and the results of
its operations for the periods covered thereby, and include all material
adjustments, which are of a normal and recurring nature, necessary for a fair
presentation. The contingency,



                                     - 4 -
<PAGE>   8



tax, bad debt and other reserves reflected on the Financial Statements are, in
all material respects, adequate, appropriate and reasonable in accordance with
GAAP.

         2.6. Absence of Changes. Since December 31, 1999, there has not been
any adverse effect that, individually or together with other adverse effects, is
material to (i) the assets, liabilities, operations, business, results of
operations or financial condition of the Company or (ii) the ability of the
Company to consummate the transactions contemplated hereby or (iii) the ability
of the Company to continue to operate its business immediately after the Closing
in substantially the same manner as such business is conducted prior to the
Closing (a "Material Adverse Effect") or any change or occurrence which could
reasonably be expected to have a Material Adverse Effect. Without limiting the
foregoing, except as set forth in Schedule 2.6, from December 31, 1999 to the
date of this Agreement, the Company has not:

                  (a) Increased, or experienced any change in any assumptions

material in the aggregate;

                  (f) Disposed of or permitted to lapse any rights to the
use of any Intellectual Property (as defined in Section 2.12) having a value,
individually or in the aggregate, in excess of $25,000, or disposed of or
disclosed (except as necessary in the conduct of its business) to any person,
other than representatives of the Lenders, any material trade secret, formula,
process or know-how not theretofore a matter of public knowledge;

                  (g) Except for any matters approved by the Compensation
Committee of the Company, granted any increase in the compensation of directors,
officers or employees (including any such increase pursuant to any bonus,
pension, profit sharing or other plan or commitment) or any increases in the
compensation payable or to become payable to any director, officer or employee,

tangible or intangible) to, or entered into any agreement or arrangement with
any stockholder, director or employee of the Company, or any other "affiliate"
of the Company, or any "associate" (as such terms are defined in Rule 405 under

pursuant to such Tax Returns and (iii) paid all other Taxes for which a notice
of assessment or demand for payment has been received. All Tax Returns are true
and correct and have been prepared in accordance with all applicable laws and

Company included as part of the Interim Financial Statements are adequate to
cover all material liabilities for Taxes of the Company for all periods ending
on or before the date of such balance sheet, and include adequate provision for
all deferred Taxes, and nothing has occurred subsequent to that date to make any
of such accruals inadequate. All Taxes of the Company for periods after the date
of such balance sheet have been paid or are adequately reserved against on the
books of the Company. The Company has timely filed all information returns or
reports, including forms 1099, that are required to be filed and has accurately
reported all information required to be included on such returns or reports in
all material respects. True copies of federal and state income tax returns of

Company, no proposed adjustments to any Tax Return pending against the Company
and no proposed adjustments to the manner in which any Tax of the Company is
determined. Except as disclosed on Schedule 2.7, each Tax Return of the Company

deficiencies resulting from such audits have been paid or are adequately
provided for in the Financial Statements), or the statute of limitations with
respect to each Tax Return has expired, and no Tax Return is under examination
by any taxing Authority. No claim has been made by a taxing Authority in a
jurisdiction where the Company does not file Tax Returns that the Company is or
may be subject to taxation by that jurisdiction.

this Agreement is made with the Lender in reliance upon the Lender's
representation to the Company that the securities will be acquired for
investment for the Lender's own account, not as a nominee or agent, and not with

violate the Securities Act. The Lender represents that its has full power and
authority to enter into this Agreement.

an opportunity to ask questions and receive answers from the Company regarding
the terms and conditions of the offering of the Notes and Warrants.

with SEC Rule 144, as presently in effect, and understands the resale

Securities Act covering such proposed disposition and such disposition is made
in accordance with such Registration Statement; or

                  (b) (i) The Lender shall have notified the Company of the
proposed disposition and (ii) if reasonably requested by the Company, the Lender
shall have furnished the Company with an opinion of counsel, reasonably

comparative percentage ownership interest in the Company in relation to the
other Principal Stockholders (the "Percentage Interest"). Weirton shall provide
each Principal Stockholder written notice of the conversion of the Lender's Note
(the "Conversion Note") not more than five business days following such
conversion. Notice of any exercise of such Call Right must be provided in
writing by such Principal Stockholder to the Lender not more than fifteen
business days from its receipt of the Conversion Notice. The closing with
respect to any exercise of a Call Right pursuant to the terms of this Article IV
(a "Call Right Closing"), shall take place at a date, time and location mutually
agreeable to the Lender and the Principal Stockholder(s) exercising the Call
Right(s). At the Call Right Closing, the Lender shall deliver the certificates
representing the shares subject to the exercised Call Right and the exercising
Principal Stockholder shall deliver the Call Right Exercise Price together with
the written representations and warranties required pursuant to Section 4.4
hereof. For purposes of this Agreement, the term "Principal Stockholders" shall
mean Bethlehem Steel Corporation, ICG, The LTV Corporation, Ryerson Toll, Inc.,
Steel Dynamics, Inc. and Weirton.

         4.2. Exercise Price of Note Shares. The exercise price for a Principal
Stockholder's Call Right ("Call Right Exercise Price") with respect to shares
received by the Lender pursuant to the conversion of the Lender's Note shall
equal the product of (i) the Principal Stockholder's Percentage Interest (or the
such lesser percentage as the Principal Stockholder elects to purchase)
multiplied by (ii) the sum of the principal amount owed by the Company on the
Note plus accrued but unpaid interest thereon.

         4.3. Calculation of Percentage Interest. A Principal Stockholder's
Percentage Interest shall be calculated by dividing the total number of shares
of the Company's capital stock owned by such Principal Stockholder by the total
number of shares (calculated on a Fully Diluted basis) of the Company's capital
stock owned by all Principal Stockholders immediately prior to the transaction
giving rise to the Call Right. For the purposes of this paragraph "Fully
Diluted" shall mean that all warrants and other securities convertible into
Common Stock issued by the Company to the Principal Stockholders and outstanding
immediately prior to the transaction giving rise to the Call Right are treated
as exercised or converted.

         4.4. Principal Stockholder's Representations and Warranties. The
Principal Stockholder must represent and warrant in writing to the Lender as to
each of the matters set forth in Article III hereof as a condition precedent to
the Lender's obligations under this Article IV.

                                  Miscellaneous

         5.1. Tax Treatment. The Company agrees to take the position that there

Internal Revenue Service; provided, however, the parties acknowledge that such
determination is subject to review by the Internal Revenue Service.

         5.2. Successors and Assigns. The terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective successors and
assigns of the parties.

<PAGE>   26





THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS (COLLECTIVELY, THE
"ACTS"), AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR

                           CONVERTIBLE PROMISSORY NOTE

U.S. $10,000,000                                              October 10, 2000

         FOR VALUE RECEIVED, MetalSite, Inc., a Delaware corporation (the
"Borrower"), promises to pay to Weirton Steel Corporation, a Delaware
corporation (the "Lender"), at a location to be designated by the Lender, the
principal amount of TEN MILLION U.S. DOLLARS ($10,000,000) (the "Principal
Amount"), upon the terms and conditions specified below.

         1. Repayment or Conversion. This convertible promissory note (this
"Note") shall be converted into common stock of the Borrower (the "Common
Stock") (with the per share conversion rate being referred to as the "Conversion
Rate"), or the Principal Amount and accrued interest thereon shall be due and
payable in accordance with the respective provisions:

         (a) Immediately prior to the closing of the Borrower's first firm
commitment underwritten public offering of its Common Stock under the Securities
Act of 1933, as amended (the "IPO"), the Lender shall have the option to convert
the Principal Amount and accrued interest thereon into that number of shares of
Common Stock determined by dividing (i) the sum of the Principal Amount and
accrued interest thereon by (ii) a price per share equal to 80% of the price per
share at which the Common Stock is sold to the public at such IPO.

         (b) At the Lender's option, upon the closing of the Borrower's next
financing with gross proceeds to the Borrower of TEN MILLION U.S. DOLLARS
($10,000,000) or more (the "Next Financing") (exclusive of any funds received by
the Borrower hereunder (including by reason of a conversion under this clause
(b))), the Lender may convert the Principal Amount and accrued interest thereon
into that number of shares of Common Stock determined by dividing (i) the sum of
the Principal Amount and accrued interest thereon by (ii) $6.00.

         (c) If prior to the event of the closing of (i) the acquisition of
Borrower by means of any transaction or series of related transactions
(including, without limitation, any reorganization, merger or consolidation)
that results in the transfer of fifty percent (50%) or more of the outstanding
voting power of the Borrower; (ii) a sale of all or substantially all of the
assets of the Borrower to another entity, or (iii) the liquidation or
dissolution of the Borrower, the Lender shall have the option to convert the
Principal Amount and accrued interest thereon into


<PAGE>   27



that number of shares of Common Stock determined by dividing (i) the sum of the
Principal Amount and accrued interest thereon by (ii) $6.00.

         (d) At any time after the date that is 90 days after the date hereof,
the Lender shall have the option to convert the Principal Amount and the accrued
interest thereon into that number of shares of Common Stock determined by
dividing (i) the outstanding Principal Amount and the accrued interest thereon
by (ii) (A) $6.00 if such conversion takes place prior to the date that is 180
days after the date hereof, or (B) an amount equal to fair market value of a
share of Common Stock, as determined by using the average price to revenues
multiple of a group of ten (10) public internet commerce companies selected by
the Board of Directors of the Borrower, if such conversion takes place on a date
that is at least 180 days after the date hereof.

         (e) On the date that is 18 months after the date hereof (the "Repayment
Date") (and without the occurrence of above Section 1(a), (b), (c) or (d)), the
Principal Amount and accrued interest, if any, shall be due and payable in full.

         2. Rate of Interest. Interest shall accrue under this Note at the rate
of five percent (5%) per annum, compounded annually, except upon the occurrence
of an Event of Acceleration set forth in Section 4 below, whereupon interest
shall begin to accrue thereafter on any unpaid principal balance at the rate of
eighteen percent (18%) per annum, compounded annually.

         3. Prepayment. Prepayment of the Principal Amount may be made at any
time without the prior written consent of the Lender; provided that prior to any
prepayment, Borrower shall give Lender 5 business days written notice of such
intention to prepay.

         4. Events of Acceleration. The entire unpaid Principal Amount and
accrued interest thereon shall become immediately due and payable upon one or
more of the following events (each an "Event of Acceleration"):

         (a) the failure of the Borrower to pay when due the Principal Amount or

         (b) the insolvency of the Borrower, the commission of an act of

assignment for the benefit of creditors, the filing by or against the Borrower
of a petition in bankruptcy or a petition for relief under the provisions of the

and the continuation of such petition without dismissal for a period of ninety

         (c) the occurrence of any default or event of default under any other

         (d) if any of the Borrower's representations and warranties under
Section 2 of the Note and Warrant Purchase Agreement of even date herewith by
and between the Borrower, Lender and the other parties named therein shall be
inaccurate.

         5. Stock Fully Paid; Reservation of Shares. All of the shares issuable
upon conversion of this Note will, upon issuance, be fully paid and
nonassessable, and, except as provided in Article IV of the Note and Warrant
Purchase Agreement, dated the date hereof, by and among the Borrower, Weirton
Steel Corporation (as Lender) and the stockholders named therein (the "Purchase
Agreement"), free from all preemptive rights, rights of first refusal or first
offer, taxes, liens and charges with respect to the issuance thereof. Commencing
with the first sale pursuant to the Next Financing and for the period thereafter
during which this Note remains outstanding, the Borrower shall at all times have
authorized and reserved for issuance sufficient shares of its Common Stock to
provide for the conversion of this Note. The Borrower agrees that its issuance
of this Note shall constitute full authority to its officers who are charged
with the duty of executing stock certificates to execute and issue the necessary
certificates for shares upon the conversion of this Note.

         6. Adjustment of Conversion Rate and Number of Shares. The number and
kind of shares into which this Note is convertible shall be subject to
adjustment from time to time upon the occurrence of certain events, as follows:

         (a) Reclassification, Consolidation or Merger. If while this Note, or
any portion hereof, remains outstanding there shall be (i) a reorganization
(other than a combination, reclassification, exchange or subdivision of shares
otherwise provided for herein), (ii) a merger or consolidation of the Borrower
with or into another corporation in which the Borrower is not the surviving
entity, or a reverse triangular merger in which the Borrower is the surviving
entity but the shares of the Borrower's capital stock outstanding immediately
prior to the merger are converted by virtue of the merger into other property,
whether in the form of securities, cash, or otherwise, or (iii) a sale or
transfer of the Borrower's properties and assets as, or substantially as, an
entirety to any other person, then, as a part of such reorganization, merger,
consolidation, sale or transfer, lawful provision shall be made so that the
holder of this Note shall thereafter be entitled to receive upon conversion of
this Note, at the Conversion Rate then in effect, the greatest number of shares
of stock or other securities or property of the successor corporation resulting
from such reorganization, merger, consolidation, sale or transfer that a holder
of the shares deliverable upon conversion of this Note would have been entitled
to receive in such reorganization, consolidation, merger, sale or transfer if
this Note had been converted immediately before such reorganization, merger,
consolidation, sale or transfer, all subject to further adjustment as provided
in this Section 6. The foregoing provisions of this paragraph shall similarly
apply to successive reorganizations, consolidations, mergers, sales and
transfers and to the stock or securities of any other corporation that are at
the time receivable upon the conversion of this Note. If the per share
consideration payable to the holder hereof for shares in connection with any
such transaction is in a form other than cash or marketable securities, then the
value of such consideration shall be determined in good faith by the Lender. In
all events, appropriate adjustment shall be made in the application of the
provisions of this Note (including




                                     - 3 -
<PAGE>   29



adjustment of the Conversion Rate and number of shares receivable pursuant to
the terms and conditions of this Note) with respect to the rights and interests
of the Lender after the transaction, to the end that the provisions of this Note
shall be applicable after that event, as near as reasonably may be, in relation
to any shares or other property deliverable after that event upon conversion of
this Note.

         (b) Split, Subdivision or Combination of Shares. If the Borrower at any
time while this Note, or any portion hereof, remains outstanding shall split or
subdivide any class of securities as to which conversion rights under this Note
exist, into a different number of securities of the same class, the number of
shares of such class issuable upon conversion of this Note immediately prior to
such split or subdivision shall be proportionately increased and the Conversion
Rate for such class of securities shall be proportionately decreased. If the
Borrower at any time while this Note, or any portion hereof, remains outstanding
shall combine any class of securities as to which conversion rights under this
Note exist, into a different number of securities of the same class, the number
of shares of such class issuable upon conversion of this Note immediately prior
to such combination shall be proportionately decreased and the Conversion Rate
for such class of securities shall be proportionately increased.

         (c) Adjustments for Dividends in Stock or Other Securities or Property.
If while this Note, or any portion hereof, remains outstanding, the holders of
any class of securities as to which conversion rights under this Note exist at
the time shall have received, or, on or after the record date fixed for the
determination of eligible stockholders, shall have become entitled to receive,
without payment therefor, other or additional stock or other securities or
property (other than cash) of the Borrower by way of dividend, then and in each
case, this Note shall represent the right to acquire, in addition to the number
of shares of such class of security receivable upon conversion of this Note, and
without payment of any additional consideration therefor, the amount of such
other or additional stock or other securities or property (other than cash) of
the Borrower that such holder would hold on the date of such conversion had it
been the holder of record of the class of security receivable upon conversion of
this Note on the date hereof and had thereafter, during the period from the date
hereof to and including the date of such conversion, retained such shares and/or
all other additional stock available by it as aforesaid during said period,
giving effect to all adjustments called for during such period by the provisions
of this Section 6.

         (d) Notice of Adjustments. Upon any adjustment of the Conversion Rate
and any increase or decrease in the number of shares into which this Note is
convertible, then, and in each such case, the Borrower, within thirty (30) days
thereafter, shall give written notice thereof to the Lender at the address of
such Lender as shown on the books of the Borrower which notice shall state the
Conversion Rate as adjusted and, if applicable, the increased or decreased
number of shares into which this Note is convertible, setting forth in
reasonable detail the method of calculation of each.

         7. Registration Rights. The Borrower hereby grants the Lender
registration rights with respect to any and all shares of Common Stock
receivable upon conversion of this Note




                                     - 4 -

pursuant to Section 1, which registration rights shall be identical to those
provided in that certain Stockholders' Agreement, dated as of July 27, 2000,
among the Borrower, the Lender and the other parties thereto (the "Stockholders
Agreement").

         8. Conversion Notice. The Lender may effect the conversion of this
Note, in whole or in part, at any time, or from time to time by the surrender of
this Note (with the notice of conversion form (the "Notice of Conversion")
attached hereto as Exhibit A duly executed) at the principal office of the
Borrower. The person or persons in whose name(s) any certificate(s) representing
shares shall be issuable upon conversion of this Note shall be deemed to have
become the holder(s) of record of, and shall be treated for all purposes as the
record holder(s) of, the shares represented thereby (and such shares shall be
deemed to have been issued) immediately prior to the close of business on the
date or dates upon which this Note is converted.

         9. Collection. If any action is instituted to collect this Note, the
Borrower promises to pay to Lender all reasonable costs and expenses (including
reasonable attorneys' fees) incurred in connection with such action.

         10. Security Agreement. Borrower hereby acknowledges that in connection
with executing this Note, the Borrower will enter into a Security Agreement with
the Lender substantially in the form attached hereto as Exhibit B whereby
Borrower shall grant to the Lender a security interest in its assets as set
forth therein.

         11. Amendments and Waivers. Any term of this Note may be amended and
the observance of any term of this Note may be waived (either generally or in a
particular instance and either retroactively or prospectively) in accordance
with Section 5.9 of the Purchase Agreement.

         12. Conflicting Agreements. In the event of any inconsistencies between
the terms of this Note and the terms of any other document related to the loan
evidenced by this Note, the terms of this Note shall prevail.

         13. Severability. The unenforceability or invalidity of any provision
or provisions of this Note as to any persons or circumstances shall not render
that provision or those provisions unenforceable or invalid as to any other
provisions or circumstances, and all provisions hereof, in all other respects,
shall remain valid and enforceable.

         14. Governing Law. This Note shall be governed by and construed under
the laws of the Commonwealth of Pennsylvania as applied to agreements among
Pennsylvania residents entered into and to be performed entirely within the
Commonwealth of Pennsylvania.

         15. Presentment, Etc. The Borrower hereby expressly waives presentment,
demand for payment, dishonor, notice of dishonor, protest, notice of protest,
and any other formality.

         16. Stockholders' Agreement. Notwithstanding any provision in this Note
to the contrary, the Borrower hereby issues this Note subject to Section 5.12 of
the Purchase Agreement, which provides in part that any Common Stock issued upon
any conversion of this Note will be subject to Articles 3 and 6 of the
Stockholders' Agreement; provided, however, the Lender may make such transfers
of Common Stock to the other stockholders of the Borrower as is contemplated by
Article IV of the Purchase Agreement, provided further, that any such
stockholders agree that the Common Stock so transferred shall after such
transfer be subject to Articles 3 and 6 of the Stockholders' Agreement.

         17. Assignment. This Note may not be transferred or assigned by Lender
without the prior written consent of the Borrower, unless such assignment is to
an Affiliate (as defined in the Purchase Agreement) of Lender.

<PAGE>   34





                               SECURITY AGREEMENT

         THIS AGREEMENT is made as of October 10, 2000, by and among MetalSite,
Inc., a Delaware corporation ("Debtor"), and Weirton Steel Corporation, a
Delaware corporation ("Secured Party").

                               STATEMENT OF FACTS

         A. Debtor and Secured Party are parties to a Convertible Promissory
Note of even date herewith (the "Note") and the Purchase Agreement as defined
therein, pursuant to which Secured Party has agreed to make certain loans to
Debtor (the "Loans").

         B. Debtor has agreed to provide Secured Party with a security interest
in the assets of Debtor as collateral security for the payment of the principal
and interest due under the Note and other obligations due thereunder and under
the Purchase Agreement.

1. NOW, THEREFORE, in consideration of the Statement of Facts and the mutual
covenants and agreements contained herein, the parties, intending to be legally
bound, covenant and agree as follows: For valuable consideration, receipt of
which is hereby acknowledged, Debtor hereby grants to Secured Party a security
interest in all Accounts, Chattel Paper, Documents, Equipment, General
Intangibles, Inventory, Instruments, and Letters of Credit (as those terms are
used in the UCC as herein defined) (collectively referred to as the
"Collateral") as security for the payment of the indebtedness and the
performance of any obligation of Debtor created under the Note and Purchase
Agreement (the obligations of Debtor under the Note and Purchase Agreement and
under this Security Agreement are collectively referred to as the
"Obligations").

2. Debtor agrees to join with Secured Party in executing one or more financing
statements pursuant to the Uniform Commercial Code of the Commonwealth of
Pennsylvania (the "UCC") in form reasonably satisfactory to Secured Party, and
Debtor will pay the cost of filing such financing statements in all public
offices wherever filing is reasonably required by the UCC in order to perfect
the security interest granted to Secured Party.

3. The security interest granted to Secured Party hereunder will be expressly
junior and subordinate to the security interest granted by Debtor to any
financing now or hereafter provided by any bank or other institutional lender of
Debtor (the "Institutional Indebtedness"), all interest accrued thereon, and all
costs of collection and enforcement incurred by lender(s) of the Institutional
Indebtedness in collecting such principal amount. Secured Party agrees to
execute and deliver any documents or instruments reasonably required by such
institutional lenders or other third parties in order to evidence the
subordination of the security interest granted to



<PAGE>   35



Secured Party hereunder, including one or more Subordination Agreements in form
and substance reasonably satisfactory to Secured Party.

4. Upon the occurrence of an Event of Acceleration (as defined in the Note), and
at any time thereafter until such Event of Acceleration is cured, Secured Party
will have the rights and remedies of a secured party under the UCC, subject to
the subordination by Secured Party in favor of the lender(s) of the
Institutional Indebtedness. Secured Party will give to Debtor 10 days' prior
written notice of the time and place of any public sale or the time after which
any private sale or any other intended disposition of the Collateral is to be
made.

5. Secured Party may exercise its rights and remedies with respect to the
Collateral without regard to any other security or sources for payment. Secured
Party will not be deemed to have waived any of its rights or remedies hereunder
unless such waiver is in writing and signed by Secured Party. No delay or
omission on the part of Secured Party in exercising any rights or remedies will
operate as a waiver of such right or remedy or any other rights or remedies. A
waiver on any one occasion will not be construed as a bar or waiver of any right
or remedy on future occasions. All rights and remedies of Secured Party
hereunder will be cumulative and may be exercised singularly or concurrently.

6. All notices or other communications required or permitted hereunder will be
in writing and will be deemed given when delivered: (i) personally, (ii) by
registered or certified mail (postage prepaid), (iii) by legible facsimile
transmission or (iv) by overnight courier (fare prepaid), in all cases addressed
as follows:

NEITHER THIS WARRANT NOR THE UNDERLYING SHARES HAVE BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS (COLLECTIVELY,
THE "ACTS"), AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR

                                 METALSITE, INC.

                       WARRANT TO PURCHASE SHARES OF STOCK


         THIS CERTIFIES THAT, for value received, Weirton Steel Corporation, or
its registered assign(s) as permitted hereunder (the "Holder"), is entitled to
subscribe for and purchase from MetalSite, Inc., a Delaware corporation (the
"Company"), at any time until and including October 9, 2010 (the "Expiration
Date"), the Shares (as defined below) at the per share exercise price set forth
below (the "Exercise Price") (each as adjusted pursuant to Section 4 hereof),
subject to the provisions and upon the terms and conditions hereinafter set
forth;

         This Warrant is subject to the following terms and conditions:

         1. Shares Issuable Upon Exercise; Exercise Price; Exercisability.

                  (a) The Shares shall mean 250,000 shares of the Company's
Common Stock, par value $.01 (the "Common Stock").

                  (b) The Exercise Price of the Shares shall be $.01 per share.

         2. Method of Exercise; Payment.

                  (a) Cash Exercise. The purchase rights represented by this
Warrant may be exercised by the Holder, in whole or in part, at any time, or
from time to time, by the surrender of this Warrant (with the notice of exercise
form (the "Notice of Exercise") attached hereto as Exhibit A duly executed) at
the principal office of the Company, and by payment to the Company of an amount
equal to the Exercise Price multiplied by the number of the Shares being
purchased, which amount may be paid, at the election of the Holder, by (i) wire
transfer or check payable to the order of the Company, (ii) cancellation by the
Holder of indebtedness or other obligations of the Company to the Holder or
(iii) a combination of (i) and (ii). The person or


<PAGE>   40



persons in whose name(s) any certificate(s) representing Shares shall be
issuable upon exercise of this Warrant shall be deemed to have become the
holder(s) of record of, and shall be treated for all purposes as the record
holder(s) of, the Shares represented thereby (and such Shares shall be deemed to
have been issued) immediately prior to the close of business on the date or
dates upon which this Warrant is exercised.

                  (b) Net Issue Exercise. In lieu of exercising this Warrant
pursuant to Section 2(a) hereof, the Holder may elect to receive a number of
Shares equal to the value (as determined below) of this Warrant (or the portion
thereof being canceled) by surrender of this Warrant at the principal office of
the Company together with Notice of Exercise in which alternative No. 1 is
initiated by the Holder. In such event, the Company shall issue to the Holder a
number of Shares computed using the following formula:

                           X=Y(A-B)
                             ------
                                A

Where             X         = the number of Shares to be issued to the Holder.

                  Y         = the number of Shares subject to this Warrant or,
                              if only a portion of this Warrant is being
                              exercised, the portion of the Warrant being
                              canceled (at the time of such calculation).

                  A         = the fair market value of one (1) Share (at the
                              date of such calculation).

                  B         = the Exercise Price (as adjusted to the date of
                              such calculation).

                  (c) Fair Market Value. For purposes of this Section 2, the
fair market value of one (1) Share shall equal:

                           (i) the average of the closing per share bid and
asked prices of the Common Stock quoted on the Nasdaq Stock Market or in the
Over-The-Counter Market Summary or the closing price quoted on any exchange on
which the Common Stock is listed, whichever is applicable, as published in the
Western Edition of The Wall Street Journal for the ten (10) trading days prior
to the date of determination of fair market value; or

                           (ii) if the Common Stock is not traded on the
Nasdaq Stock Market or Over-The-Counter or on an exchange, the fair market value
of a Share shall be agreed upon by the parties hereto. If parties cannot agree
on the fair market value within five (5) business days of delivery of the Notice
of Exercise, the Board of Directors in good faith shall determine the fair
market value of a Share in the same manner used to determine the fair market
value of incentive stock options granted by the Company.

                           (iii) Stock Certificates. In the event of any
exercise of the rights represented by this Warrant, as promptly as practicable
on or after the date of exercise and in any event within ten (10) days
thereafter, the Company at its expense shall issue and deliver to the person or
persons entitled to receive the same a certificate or certificates for the
number of Shares issuable upon such exercise. In the event this Warrant is
exercised in part, the Company at its expense will execute and deliver a new
Warrant of like tenor exercisable for the number of Shares for which this
Warrant may then be exercised.

                  (d) Taxes. The issuance of the Shares upon the exercise of
this Warrant, and the delivery of certificates or other instruments representing
such Shares, shall be made without charge to the Holder for any tax or other
charge in respect of such issuance.

         3. Stock Fully Paid; Reservation of Shares. All of the Shares issuable
upon the exercise of the rights represented by this Warrant will, upon issuance
and receipt of the Exercise Price therefor, be fully paid and nonassessable,
and free from all preemptive rights, rights of first refusal or first offer,
taxes, liens and charges with respect to the issuance thereof. During the period
within which the rights represented by this Warrant may be exercised, the
Company shall at all times have authorized and reserved for issuance sufficient
shares of its Common Stock to provide for the exercise of the rights represented
by this Warrant. The Company shall take all steps necessary to amend its charter
documents to provide sufficient reserves of shares of Common Stock issuable upon
exercise of this Warrant. The Company agrees that its issuance of this Warrant
shall constitute full authority to its officers who are charged with the duty of
executing stock certificates to execute and issue the necessary certificates for
Shares upon the exercise of this Warrant.

         4. Adjustment of Exercise Price and Number of Shares. Subject to the
provisions of Section 14 hereof, the number and kind of Shares purchasable upon
the exercise of this Warrant and the Exercise Price therefor shall be subject to
adjustment from time to time upon the occurrence of certain events, as follows:

                  (a) Adjustment for Reclassification, Consolidation or Merger.
If while this Warrant, or any portion hereof, remains outstanding and unexpired
there shall be (i) a reorganization (other than a combination, reclassification,
exchange or subdivision of shares otherwise provided for herein), (ii) a merger
or consolidation of the Company with or into another corporation in which the
Company is not the surviving entity, or a reverse triangular merger in which the
Company is the surviving entity but the shares of the Company's capital stock
outstanding immediately prior to the merger are converted by virtue of the
merger into other property, whether in the form of securities, cash, or
otherwise, or (iii) a sale or transfer of the Company's properties and assets
as, or substantially as, an entirety to any other person, then, as a part of
such reorganization, merger, consolidation, sale or transfer, lawful provision
shall be made so that the holder of this Warrant shall thereafter be entitled to
receive upon exercise of this Warrant, during the period specified herein and
upon payment of the Exercise Price then in effect, the greatest number of shares
of stock or other securities or property of the successor corporation resulting
from such reorganization, merger, consolidation, sale or transfer that a




                                     - 3 -
<PAGE>   42



holder of the shares deliverable upon exercise of this Warrant would have been
entitled to receive in such reorganization, consolidation, merger, sale or
transfer if this Warrant had been exercised immediately before such
reorganization, merger, consolidation, sale or transfer, all subject to further
adjustment as provided in this Section 4. The foregoing provisions of this
paragraph shall similarly apply to successive reorganizations, consolidations,
mergers, sales and transfers and to the stock or securities of any other
corporation that are at the time receivable upon the exercise of this Warrant.
If the per share consideration payable to the holder hereof for shares in
connection with any such transaction is in a form other than cash or marketable
securities, then the value of such consideration shall be determined in good
faith by the Holder. In all events, appropriate adjustment shall be made in the
application of the provisions of this Warrant (including adjustment of the
Exercise Price and number of Shares purchasable pursuant to the terms and
conditions of this Warrant) with respect to the rights and interests of the
Holder after the transaction, to the end that the provisions of this Warrant
shall be applicable after that event, as near as reasonably may be, in relation
to any shares or other property deliverable after that event upon exercise of
this Warrant.

                  (b) Adjustments for Split, Subdivision or Combination of
Shares. If the Company at any time while this Warrant, or any portion hereof,
remains outstanding and unexpired shall split or subdivide any class of
securities as to which purchase rights under this Warrant exist, into a
different number of securities of the same class, the number of Shares of such
class issuable upon exercise of this Warrant immediately prior to such split or
subdivision shall be proportionately increased and the Exercise Price for such
class of securities shall be proportionately decreased. If the Company at any
time while this Warrant, or any portion hereof, remains outstanding and
unexpired shall combine any class of securities as to which purchase rights
under this Warrant exist, into a different number of securities of the same
class, the number of Shares of such class issuable upon exercise of this Warrant
immediately prior to such combination shall be proportionately decreased and the
Exercise Price for such class of securities shall be proportionately increased.

                  (c) Adjustments for Dividends in Stock or Other Securities or
Property. If while this Warrant, or any portion hereof, remains outstanding and
unexpired, the holders of any class of securities as to which purchase rights
under this Warrant exist at the time shall have received, or, on or after the
record date fixed for the determination of eligible stockholders, shall have
become entitled to receive, without payment therefor, other or additional stock
or other securities or property (other than cash) of the Company by way of
dividend, then and in each case, this Warrant shall represent the right to
acquire, in addition to the number of shares of such class of security
receivable upon exercise of this Warrant, and without payment of any additional
consideration therefor, the amount of such other or additional stock or other
securities or property (other than cash) of the Company that such holder would
hold on the date of such exercise had it been the holder of record of the class
of security receivable upon exercise of this Warrant on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock available
by it as aforesaid during said period, giving effect to all adjustments called
for during such period by the provisions of this Section 4.

                  (d) Notice of Adjustments. Upon any adjustment of the Exercise
Price and any increase or decrease in the number of Shares purchasable upon the
exercise of this Warrant, then, and in each such case, the Company, within
thirty (30) days thereafter, shall give written notice thereof to the Holder at
the address of such Holder as shown on the books of the Company which notice
shall state the Exercise Price as adjusted and, if applicable, the increased or
decreased number of Shares purchasable upon the exercise of this Warrant,
setting forth in reasonable detail the method of calculation of each.

         5.       Notices.

                  (a) In the event that the Company shall propose at any time:

                           (i) to declare any dividend or distribution upon its
Common Stock (or other stock or securities at the time receivable upon the
exercise of this Warrant) whether in cash, property, stock or other securities,
whether or not a regular cash dividend and whether or not out of earnings or
earned surplus;

                           (ii) to offer for subscription pro rata to the
holders of any class or series of its stock any additional shares of stock of
any class or series or other rights;

                           (iii) to merge or consolidate with or into any other
corporation, or sell, lease or convey all or substantially all its property or
business, or to voluntarily liquidate, dissolve or wind up; or

                           (iv) to effect an initial public offering of the
Common Stock (the "Public Offering") pursuant to an effective registration
statement filed with the Securities and Exchange Commission pursuant to the
Securities Act of 1933, as amended (the "Act");

then, in connection with each such event, the Company shall send to the Holder
(1) at least ten (10) days' prior written notice of the date on which a record
shall be taken for such dividend, distribution or subscription rights (and
specifying the date on which the holders of Common Stock shall be entitled
thereto) or for determining rights to vote, if any; and (2) at least ten (10)
days' prior written notice of the date when the same shall take place, and the
date, if any is to be fixed, on which the holders of record of Common Stock
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event). Notwithstanding the
above, the ten (10) days' notice requirement may be shortened or waived upon the
written consent of the Holder.

                  (b) Any written notice by the Company required or permitted
hereunder shall be given by hand delivery or first class mail, postage prepaid,
addressed to the Holder at the address shown on the books of the Company for the
Holder.

         6. Registration Rights. The Company hereby grants the Holder
registration rights with respect to the shares receivable upon the exercise
hereof identical to those provided in that




                                     - 5 -
<PAGE>   44



certain Stockholders' Agreement, dated as of July 27, 2000, among the Company,
Weirton Steel Corporation and the other parties thereto (the "Stockholders
Agreement").

         7. Legend. Each certificate evidencing the Shares issued upon exercise
of this Warrant, or transfer of such shares (other than a transfer registered
under the Act or any subsequent transfer of shares so registered) shall be
stamped or imprinted with a legend substantially in the following form:

NEITHER THIS WARRANT NOR THE UNDERLYING SHARES HAVE BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS (COLLECTIVELY,
THE "ACTS"), AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR
HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACTS OR UNLESS AN OPINION OF
COUNSEL IS DELIVERED TO THE CORPORATION IN FORM AND SUBSTANCE SATISFACTORY TO
THE CORPORATION TO THE EFFECT THAT AN EXEMPTION FROM REGISTRATION IS AVAILABLE.

         8. Removal of Legend. Upon request of a holder of a certificate with
the legends referred to in Section 7 hereof, the Company shall issue to such
holder a new certificate therefor free of any transfer legend, if, with such
request, the Company shall have received an opinion of counsel to the effect
that any transfer by such holder of the shares evidenced by such certificate
will not violate the Act and applicable state securities laws and that such
shares will no longer be subject to rights of first offer and voting agreements.

         9. Fractional Shares. No fractional shares will be issued in connection
with any exercise hereunder. Any fraction of a share resulting from any
calculation will be rounded up to the next whole share.

         10. Transferability. Subject to compliance with applicable federal and
state securities laws and Section 15 hereof, this Warrant and all rights
hereunder are transferable, in whole or in part, without charge to the Holder
hereof (except for transfer taxes), upon surrender of this Warrant properly
endorsed.

         11. Representations and Warranties of the Company. The Company
represents and warrants to the Holder as follows:

                  (a) This Warrant has been duly authorized and executed
by the Company and is a valid and binding obligation of the Company enforceable
in accordance with its terms;

                  (b) Prior to the date that this Warrant becomes exercisable,
the Shares will have been duly authorized and reserved for issuance by the
Company and, when issued in accordance with the terms hereof, will be validly
issued, fully paid and nonassessable;





                                     - 6 -
<PAGE>   45



                  (c) The execution and delivery of this Warrant are not, and
the issuance of the Shares upon exercise of this Warrant in accordance with the
terms hereof will not be, inconsistent with the Company's charter documents.

         12. Representations and Warranties by the Holder. The Holder represents
and warrants to the Company as follows:

                  (a) This Warrant is being acquired for its own account, for
investment and not with a view to, or for resale in connection with, any
distribution thereof within the meaning of the Act. Upon exercise of this
Warrant, the Holder shall, if so requested by the Company, confirm in writing,
in a form reasonably satisfactory to the Company, that the Shares issuable upon
exercise of this Warrant are being acquired for investment and not with a view
toward distribution or resale that would violate the Act.

                  (b) The Holder understands that the Warrant and the Shares
have not been registered under the Act by reason of their issuance in a
transaction exempt from the registration and prospectus delivery requirements of
the Act pursuant to Section 4(2) thereof, and that they must be held by the
Holder indefinitely, and that the Holder must therefore bear the economic risk
of such investment indefinitely, unless a subsequent disposition thereof is
registered under the Act or is exempted from such registration.

                  (c) The Holder has such knowledge and experience in financial
and business matters that it is capable of evaluating the merits and risks of
the purchase of this Warrant and the Shares purchasable pursuant to the terms of
this Warrant and of protecting its interests in connection therewith.

                  (d) The Holder is able to bear the economic risk of the
purchase of the Shares pursuant to the terms of this Warrant.

         13. Rights of Stockholders. Subject to Sections 4 and 5 hereof, no
holder of this Warrant shall be entitled, as a Warrant holder, to vote or
receive dividends or be deemed the holder of Common Stock or any other
securities of the Company that may at any time be issuable on the exercise
hereof for any purpose, nor shall anything contained herein be construed to
confer upon the holder of this Warrant, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action (whether upon any recapitalization,
issuance of stock, reclassification of stock, change of par value,
consolidation, merger, conveyance, or otherwise) or to receive notice of
meetings, or to receive dividends or subscription rights or otherwise until the
Warrant shall have been exercised and the Shares purchasable upon the exercise
hereof shall have become deliverable, as provided herein.

         14. Expiration of Warrant. This Warrant shall expire and shall no
longer be exercisable as of 5:00 p.m., Eastern Standard Time, on October 9,
2010.

in this Warrant to the contrary, this Warrant may not be transferred or assigned
by Holder without the prior written consent of the Company, unless such
assignment is to an Affiliate (as defined in the Stockholders' Agreement of
Holder and any Common Stock issued upon the exercise of this Warrant is subject
to Articles 3 and 6 of the Stockholders' Agreement.

         16. Miscellaneous.

under and in accordance with the laws of the Commonwealth of Pennsylvania

respective parties contained herein or made pursuant to this Warrant shall
survive the execution and delivery of this Warrant.

         (d) The terms of this Warrant shall be binding upon and shall inure to

holders hereof and of the Shares issued or issuable upon the exercise hereof.

constitute the full and entire understanding and agreement between the parties

         (f) The Company shall not, by amendment of its charter documents, or
through any other means, directly or indirectly, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant and shall at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such action as may be necessary or appropriate in order to protect
the rights of the holder of this Warrant against impairment.

         (g) Upon receipt of evidence reasonably satisfactory to the Company of
the loss, theft, destruction or mutilation of this Warrant and, in the case of
any such loss, theft or destruction, upon delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, upon surrender and cancellation of such Warrant, the Company,
at its expense, will execute and deliver to the holder of record, in lieu
thereof, a new Warrant of like date and tenor.
